Programs & Examples On #Pdfpage

I have build such kind of application using approximatively the same approach except :

• I cache the generated image on the disk and always generate two to three images in advance in a separate thread.
• I don't overlay with a UIImage but instead draw the image in the layer when zooming is 1. Those tiles will be released automatically when memory warnings are issued.

Whenever the user start zooming, I acquire the CGPDFPage and render it using the appropriate CTM. The code in - (void)drawLayer: (CALayer*)layer inContext: (CGContextRef) context is like :

CGAffineTransform currentCTM = CGContextGetCTM(context);    
if (currentCTM.a == 1.0 && baseImage) {
    //Calculate ideal scale
    CGFloat scaleForWidth = baseImage.size.width/self.bounds.size.width;
    CGFloat scaleForHeight = baseImage.size.height/self.bounds.size.height; 
    CGFloat imageScaleFactor = MAX(scaleForWidth, scaleForHeight);

    CGSize imageSize = CGSizeMake(baseImage.size.width/imageScaleFactor, baseImage.size.height/imageScaleFactor);
    CGRect imageRect = CGRectMake((self.bounds.size.width-imageSize.width)/2, (self.bounds.size.height-imageSize.height)/2, imageSize.width, imageSize.height);
    CGContextDrawImage(context, imageRect, [baseImage CGImage]);
} else {
    @synchronized(issue) { 
        CGPDFPageRef pdfPage = CGPDFDocumentGetPage(issue.pdfDoc, pageIndex+1);
        pdfToPageTransform = CGPDFPageGetDrawingTransform(pdfPage, kCGPDFMediaBox, layer.bounds, 0, true);
        CGContextConcatCTM(context, pdfToPageTransform);    
        CGContextDrawPDFPage(context, pdfPage);
    }
}

issue is the object containg the CGPDFDocumentRef. I synchronize the part where I access the pdfDoc property because I release it and recreate it when receiving memoryWarnings. It seems that the CGPDFDocumentRef object do some internal caching that I did not find how to get rid of.

If you're a FP (functional programming) fan, Ramda has a neat helper function for this called defaultTo :

usage:

const result = defaultTo(30)(value)

It's more useful when dealing with undefined boolean values:

const result2 = defaultTo(false)(dashboard.someValue)

Try using MS Access instead. Create a new file and select 'Project using existing data' template. This will create .adp file.

Then simply open your table and press Ctrl+Enter for new line.

Pasting from clipboard also works correctly.

Please use below function if you don't want to round off.

function ConvertToDecimal(num) {
    num = num.toString(); //If it's not already a String
    num = num.slice(0, (num.indexOf(".")) + 3); //With 3 exposing the hundredths place
   alert('M : ' +  Number(num)); //If you need it back as a Number    
}

step 1:

Download dex2jar here. Create a java project and paste (dex2jar-0.0.7.11-SNAPSHOT/lib ) jar files .

Copy apk file into java project

Run it and after refresh the project ,you get jar file .Using java decompiler you can view all java class files

step 2: Download java decompiler here

explode() might be the function you are looking for

$array = explode(' ',$str);

You can simply use the jQuery Validate plugin as follows.

jQuery:

$(document).ready(function () {

    $('#myform').validate({ // initialize the plugin
        rules: {
            field1: {
                required: true,
                email: true
            },
            field2: {
                required: true,
                minlength: 5
            }
        }
    });

});

HTML:

<form id="myform">
    <input type="text" name="field1" />
    <input type="text" name="field2" />
    <input type="submit" />
</form>

According to my tests, in terms of performance and readability my recommendation is:

tail -n+N | head -1

N is the line number that you want. For example, tail -n+7 input.txt | head -1 will print the 7th line of the file.

tail -n+N will print everything starting from line N, and head -1 will make it stop after one line.

The alternative head -N | tail -1 is perhaps slightly more readable. For example, this will print the 7th line:

head -7 input.txt | tail -1

When it comes to performance, there is not much difference for smaller sizes, but it will be outperformed by the tail | head (from above) when the files become huge.

The top-voted sed 'NUMq;d' is interesting to know, but I would argue that it will be understood by fewer people out of the box than the head/tail solution and it is also slower than tail/head.

In my tests, both tails/heads versions outperformed sed 'NUMq;d' consistently. That is in line with the other benchmarks that were posted. It is hard to find a case where tails/heads was really bad. It is also not surprising, as these are operations that you would expect to be heavily optimized in a modern Unix system.

To get an idea about the performance differences, these are the number that I get for a huge file (9.3G):

• tail -n+N | head -1: 3.7 sec
• head -N | tail -1: 4.6 sec
• sed Nq;d: 18.8 sec

Results may differ, but the performance head | tail and tail | head is, in general, comparable for smaller inputs, and sed is always slower by a significant factor (around 5x or so).

To reproduce my benchmark, you can try the following, but be warned that it will create a 9.3G file in the current working directory:

#!/bin/bash
readonly file=tmp-input.txt
readonly size=1000000000
readonly pos=500000000
readonly retries=3

seq 1 $size > $file
echo "*** head -N | tail -1 ***"
for i in $(seq 1 $retries) ; do
    time head "-$pos" $file | tail -1
done
echo "-------------------------"
echo
echo "*** tail -n+N | head -1 ***"
echo

seq 1 $size > $file
ls -alhg $file
for i in $(seq 1 $retries) ; do
    time tail -n+$pos $file | head -1
done
echo "-------------------------"
echo
echo "*** sed Nq;d ***"
echo

seq 1 $size > $file
ls -alhg $file
for i in $(seq 1 $retries) ; do
    time sed $pos'q;d' $file
done
/bin/rm $file

Here is the output of a run on my machine (ThinkPad X1 Carbon with an SSD and 16G of memory). I assume in the final run everything will come from the cache, not from disk:

If the string is Unicode the easiest way is:

import base64                                                        

a = base64.b64encode(bytes(u'complex string: ñáéíóúÑ', "utf-8"))

# a: b'Y29tcGxleCBzdHJpbmc6IMOxw6HDqcOtw7PDusOR'

b = base64.b64decode(a).decode("utf-8", "ignore")                    

print(b)
# b :complex string: ñáéíóúÑ

You can get a subset of the np.set_printoptions functionality from the np.array_str command, which applies only to a single print statement.

http://docs.scipy.org/doc/numpy/reference/generated/numpy.array_str.html

For example:

In [27]: x = np.array([[1.1, 0.9, 1e-6]]*3)

In [28]: print x
[[  1.10000000e+00   9.00000000e-01   1.00000000e-06]
 [  1.10000000e+00   9.00000000e-01   1.00000000e-06]
 [  1.10000000e+00   9.00000000e-01   1.00000000e-06]]

In [29]: print np.array_str(x, precision=2)
[[  1.10e+00   9.00e-01   1.00e-06]
 [  1.10e+00   9.00e-01   1.00e-06]
 [  1.10e+00   9.00e-01   1.00e-06]]

In [30]: print np.array_str(x, precision=2, suppress_small=True)
[[ 1.1  0.9  0. ]
 [ 1.1  0.9  0. ]
 [ 1.1  0.9  0. ]]

Just put below code in AndroidManifest :

<uses-permission android:name="android.permission.INTERNET" /> 
<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>

According to Angular Doc:
Since ngBind is an element attribute, it makes the bindings invisible to the user while the page is loading... it's the main difference...

Basically until every dom elements not loaded, we can not see them and because ngBind is attribute on the element, it waits until the doms come into play... more info below

ngBind
- directive in module ng

The ngBind attribute tells AngularJS to replace the text content of the specified HTML element with the value of a given expression, and to update the text content when the value of that expression changes.

Typically, you don't use ngBind directly, but instead you use the double curly markup like {{ expression }} which is similar but less verbose.

It is preferable to use ngBind instead of {{ expression }} if a template is momentarily displayed by the browser in its raw state before AngularJS compiles it. Since ngBind is an element attribute, it makes the bindings invisible to the user while the page is loading.

An alternative solution to this problem would be using the ngCloak directive. visit here

for more info about the ngbind visit this page: https://docs.angularjs.org/api/ng/directive/ngBind

You could do something like this as attribute, ng-bind:

<div ng-bind="my.name"></div>

or do interpolation as below:

<div>{{my.name}}</div>

or this way with ng-cloak attributes in AngularJs:

<div id="my-name" ng-cloak>{{my.name}}</div>

ng-cloak avoid flashing on the dom and wait until all be ready! this is equal to ng-bind attribute...

If you need to display all the records after 2014-09-01, add this to your query:

SELECT * FROM Events
WHERE Format(Events.DATE_TIME,'yyyy-MM-dd hh:mm:ss')  >= Format("2014-09-01 00:00:00","yyyy-MM-dd hh:mm:ss")

UPDATE: THIS ANSWER IS SERIOUSLY OUTDATED. Please use the recommendations from the https://stackoverflow.com/a/10402129/251311 instead.

You can either use

var md5 = new MD5CryptoServiceProvider();
var md5data = md5.ComputeHash(data);

or

var sha1 = new SHA1CryptoServiceProvider();
var sha1data = sha1.ComputeHash(data);

To get data as byte array you could use

var data = Encoding.ASCII.GetBytes(password);

and to get back string from md5data or sha1data

var hashedPassword = ASCIIEncoding.GetString(md5data);

The answer is "Yes, But..."

But cPython cannot when you are using regular threads for concurrency.

You can either use something like multiprocessing, celery or mpi4py to split the parallel work into another process;

Or you can use something like Jython or IronPython to use an alternative interpreter that doesn't have a GIL.

A softer solution is to use libraries that don't run afoul of the GIL for heavy CPU tasks, for instance numpy can do the heavy lifting while not retaining the GIL, so other python threads can proceed. You can also use the ctypes library in this way.

If you are not doing CPU bound work, you can ignore the GIL issue entirely (kind of) since python won't aquire the GIL while it's waiting for IO.

Do you want your function to react to an array argument or variable arguments? If the latter, try:

var func = function(...rest) {
  alert(rest.length);

  // In JS, don't use for..in with arrays
  // use for..of that consumes array's pre-defined iterator
  // or a more functional approach
  rest.forEach((v) => console.log(v));
};

But if you wish to handle an array argument

var fn = function(arr) {
  alert(arr.length);

  for(var i of arr) {
    console.log(i);
  }
};

The solution angular.element(document.getElementById('ID')).scope().get() stopped working for me in angular 1.5.2. Sombody mention in a comment that this doesn't work in 1.4.9 also. I fixed it by storing the scope in a global variable:

var scopeHolder;
angular.module('fooApp').controller('appCtrl', function ($scope) {
    $scope = function bar(){
        console.log("foo");        
    };
    scopeHolder = $scope;
})

call from custom code:

scopeHolder.bar()

if you wants to restrict the scope to only this method. To minimize the exposure of whole scope. use following technique.

var scopeHolder;
angular.module('fooApp').controller('appCtrl', function ($scope) {
    $scope.bar = function(){
        console.log("foo");        
    };
    scopeHolder = $scope.bar;
})

call from custom code:

scopeHolder()

As the question is asked simply use @Min(1) instead of @size on integer fields and it will work.

This should work:

background: -moz-linear-gradient(center top , #fad59f, #fa9907) repeat scroll 0 0 transparent;
 /* For WebKit (Safari, Google Chrome etc) */
background: -webkit-gradient(linear, left top, left bottom, from(#fad59f), to(#fa9907));
/* For Mozilla/Gecko (Firefox etc) */
background: -moz-linear-gradient(top, #fad59f, #fa9907);
/* For Internet Explorer 5.5 - 7 */
filter: progid:DXImageTransform.Microsoft.gradient(startColorstr=#fad59f, endColorstr=#fa9907);
/* For Internet Explorer 8 */
-ms-filter: "progid:DXImageTransform.Microsoft.gradient(startColorstr=#fad59f, endColorstr=#fa9907)";

Otherwise generate using the following link and get the code.

http://www.colorzilla.com/gradient-editor/

It's probably easiest to create your query object directly as:

  Test.find({
      $and: [
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ]
  }, function (err, results) {
      ...
  }

But you can also use the Query#and helper that's available in recent 3.x Mongoose releases:

  Test.find()
      .and([
          { $or: [{a: 1}, {b: 1}] },
          { $or: [{c: 1}, {d: 1}] }
      ])
      .exec(function (err, results) {
          ...
      });

Use List<T>.Insert

While not relevant to your specific example, if performance is important also consider using LinkedList<T> because inserting an item to the start of a List<T> requires all items to be moved over. See When should I use a List vs a LinkedList.

I'm having same scenario, this worked for me but i'm not having the "hide/show" feature you have. So perhaps you could first check if you get the focus when you have the field always visible, and then try to solve why does not work when you change visibility (probably that's why you need to apply a sleep or a promise)

To set focus, this is the only change you need to do:

your Html mat input should be:

<input #yourControlName matInput>

in your TS class, reference like this in the variables section (

export class blabla...
    @ViewChild("yourControlName") yourControl : ElementRef;

Your button it's fine, calling:

  showSearch(){
       ///blabla... then finally:
       this.yourControl.nativeElement.focus();
}

and that's it. You can check this solution on this post that I found, so thanks to --> https://codeburst.io/focusing-on-form-elements-the-angular-way-e9a78725c04f

Try this:

setDefaultCloseOperation(DO_NOTHING_ON_CLOSE);

It will work.

MSDN

String mystr = "PER 343573";
String number = mystr.Substring(mystr.Length-6);

EDIT: too slow...

I think there's no foolproof way to do it. For example, consider the following:

$t = "A+B";

Is that an URL encoded "A B" or does it need to be encoded to "A%2BB"?

Try this,

monthly_mean.plot(y='A', use_index=True)

items=re.findall("token.*$",s,re.MULTILINE)
>>> for x in items:

you can also get the line if there are other characters before token

items=re.findall("^.*token.*$",s,re.MULTILINE)

The above works like grep token on unix and keyword 'in' or .contains in python and C#

s='''
qwertyuiop
asdfghjkl

zxcvbnm
token qwerty

asdfghjklñ
'''

http://pythex.org/ matches the following 2 lines

....
....
token qwerty

Eagerly evaluated (2.x range):

[x * .5 for x in range(10)]

Lazily evaluated (2.x xrange, 3.x range):

itertools.imap(lambda x: x * .5, xrange(10)) # or range(10) as appropriate

Alternately:

itertools.islice(itertools.imap(lambda x: x * .5, itertools.count()), 10)
# without applying the `islice`, we get an infinite stream of half-integers.

Quick and Dirty Way!

It's not a good way, but for me it seems the most simplest.

Add an anchor tag which contains the modal data-target and data-toggle, have an id associated with it. (Can be added mostly anywhere in the html view)

<a href="" data-toggle="modal" data-target="#myModal" id="myModalShower"></a>

Now,

Inside the angular controller, from where you want to trigger the modal just use

angular.element('#myModalShower').trigger('click');

This will mimic a click to the button based on the angular code and the modal will appear.

We were also facing this issue when using IE version 11 to access our React app (create-react-app with react version 16.0.0 with jQuery v3.1.1) on the enterprise intranet. To solve it, i simply followed the directions at this url which are also listed below:

1. Make sure to set the DOCTYPE to standards mode by making sure the first line of the master file is: <!DOCTYPE html>

2. Force IE 11 to use the latest internal version by including the following meta tag in the head tag: <meta http-equiv="X-UA-Compatible" content="IE=edge;" />

NOTE: I did not face the problem when using IE to access the app in development mode on my local machine (localhost:3000). The problem occurred only when accessing the app deployed to the DEV server on the company Intranet, probably because of some company wide Windows OS policy settings and/or IE Internet Options.

In my case the element that generated the Exception was a button belonging to a form. I replaced

WebElement btnLogin = driver.findElement(By.cssSelector("button"));
btnLogin.click();

with

btnLogin.submit();

My environment was chromedriver windows 10

No one has provided a solution that would work cross-form. I know it wasn't specifically asked but I am working in a linux environment where most of the solutions (as at the time I post this) would provide an error.

Hardcoding path separators (as well as other things) will give an error in anything but Windows systems.

In my original solution I used:

char filesep = Path.DirectorySeparatorChar;
string datapath = $"..{filesep}..{filesep}";

However after seeing some of the answers here I adjusted it to be:

string datapath = Directory.GetParent(Directory.GetParent(Directory.GetCurrentDirectory()).FullName).FullName; 

Convert an array to a string in PHP:

1. Use the PHP join function like this:

   $my_array = array(4, 1, 8);
   
   print_r($my_array);
   Array
   (
       [0] => 4
       [1] => 1
       [2] => 8
   )
   
   $result_string = join(',', $my_array);
   echo $result_string;
   

   Which delimits the items in the array by comma into a string:

   4,1,8
   

2. Or use the PHP implode function like this:

   $my_array = array(4, 1, 8);
   echo implode($my_array);
   

   Which prints:

   418
   

3. Here is what happens if you join or implode key value pairs in a PHP array

   php> $keyvalues = array();
   
   php> $keyvalues['foo'] = "bar";
   
   php> $keyvalues['pyramid'] = "power";
   
   php> print_r($keyvalues);
   Array
   (
       [foo] => bar
       [pyramid] => power
   )
   
   php> echo join(',', $keyvalues);
   bar,power
   php> echo implode($keyvalues);
   barpower
   php>

If the external library is in a folder that is under the project then

File -> Settings -> Project -> Project structure -> select the folder and Mark as Sources!

If not, add content root, and do similar things.

Google play finds you as developer via your keystore.

and maybe your country IP is banned on Google when you generate your new keystore.

change your IP Address and generate new keystore, the problem will be fixed.

if you didn't succeed, use another Gmail in Android Studio and generate new keystore.

You should escape it with another backslash \:

print('\\')

In dplyr 0.3 this can be easily achieved using the distinct() method.

Here is an example:

distinct_df = df %>% distinct(field1)

You can get a vector of the distinct values with:

distinct_vector = distinct_df$field1

You can also select a subset of columns at the same time as you perform the distinct() call, which can be cleaner to look at if you examine the data frame using head/tail/glimpse.:

distinct_df = df %>% distinct(field1) %>% select(field1) distinct_vector = distinct_df$field1

You don't need to muck about with extracting parts of the date. Just cast it to a date using to_date and the format in which its stored, then cast that date to a char in the format you want. Like this:

select to_char(to_date('1/10/2011','mm/dd/yyyy'),'mm-dd-yyyy') from dual

If sql server is installed on your machine, you should check

Programs -> Microsoft SQL Server 20XX -> Configuration Tools -> SQL Server Configuration Manager -> SQL Server Services You'll see "SQL Server (MSSQLSERVER)"

Programs -> Microsoft SQL Server 20XX -> Configuration Tools -> SQL Server Configuration Manager -> SQL Server Network Configuration -> Protocols for MSSQLSERVER -> TCP/IP Make sure it's using port number 1433

If you want to see if the port is open and listening try this from your command prompt... telnet 127.0.0.1 1433

And yes, SQL Express installs use localhost\SQLEXPRESS as the instance name by default.

I just had an issue where I needed to solve this properly.

Via Ajax, a script gets X (0-10) messages. What I wanted to do: Add one message to the DOM every 10 Seconds.

the code I ended up with:

$.each(messages, function(idx, el){
  window.setTimeout(function(){
    doSomething(el);
  },Math.floor(idx+1)*10000);
});

Basically, think of the timeouts as a "timeline" of your script.

This is what we WANT to code:

DoSomething();
WaitAndDoNothing(5000);
DoSomethingOther();
WaitAndDoNothing(5000);
DoEvenMore();

This is HOW WE NEED TO TELL IT TO THE JAVASCRIPT:

At Runtime 0    : DoSomething();
At Runtime 5000 : DoSomethingOther();
At Runtime 10000: DoEvenMore();

Hope this helps.

For those who are looking to sort whether or not there are optgroup :

/**
 * Sorting options 
 * and optgroups
 * 
 * @param selElem select element
 * @param optionBeforeGroup ?bool if null ignores, if true option appear before group else option appear after group
 */
function sortSelect(selElem, optionBeforeGroup = null) {
    let initialValue = selElem.tagName === "SELECT" ? selElem.value : null; 
    let allChildrens = Array.prototype.slice.call(selElem.childNodes);
    let childrens = [];

    for (let i = 0; i < allChildrens.length; i++) {
        if (allChildrens[i].parentNode === selElem && ["OPTGROUP", "OPTION"].includes(allChildrens[i].tagName||"")) {

After hours of searching and trying I found out that on a x64 server the MSOnline modules must be installed for x64, and some programs that need to run them are using the x86 PS version, so they will never find it.

[SOLUTION] What I did to solve the issue was:

Copy the folders called MSOnline and MSOnline Extended from the source

C:\Windows\System32\WindowsPowerShell\v1.0\Modules\

to the folder

C:\Windows\SysWOW64\WindowsPowerShell\v1.0\Modules\

And then in PS run the Import-Module MSOnline, and it will automatically get the module :D

In the absence of more detailed info:

using(var dbContext = new dbDataContext())
{
    var data = dbContext.SomeTable.SingleOrDefault(row => row.id == requiredId);
    if(data != null)
    {
        data.SomeField = newValue;
    }
    dbContext.SubmitChanges();
}

qImageView.setImageResource(R.drawable.img2);

I think this will help you

library(lubridate) if your date format is like this '04/24/2017 05:35:00'then change it like below prods.all$Date2<-gsub("/","-",prods.all$Date2) then change the date format parse_date_time(prods.all$Date2, orders="mdy hms")

You can use your own function for this.

try it: http://jsfiddle.net/xstLr7aj/

function string_to_slug(str) {
  str = str.replace(/^\s+|\s+$/g, ''); // trim
  str = str.toLowerCase();

  // remove accents, swap ñ for n, etc
  var from = "àáäâèéëêìíïîòóöôùúüûñç·/_,:;";
  var to   = "aaaaeeeeiiiioooouuuunc------";
  for (var i=0, l=from.length ; i<l ; i++) {
    str = str.replace(new RegExp(from.charAt(i), 'g'), to.charAt(i));
  }

  str = str.replace(/[^a-z0-9 -]/g, '') // remove invalid chars
    .replace(/\s+/g, '-') // collapse whitespace and replace by -
    .replace(/-+/g, '-'); // collapse dashes

  return str;
}
$(document).ready(function() {
    $('#test').submit(function(){
        var val = string_to_slug($('#t').val());
        alert(val);
        return false;
    });
});

On Windows 10, to create the virtual environment, I replace "pip mkvirtualenv myproject" by "mkvirtualenv myproject" and that works well.

By stacking each switch case, you achieve the OR condition.

switch(myvar)
{
    case 2:
    case 5:
    ...
    break;

    case 7:
    case 12:
    ...
    break;
    ...
}

Including COM Objects:

heat generates all most (if not all) the registry entries and other configuration needed for them. Rejoice!

Including Managed COM Objects (aka, .NET or C# COM objects)

Using heat on a managed COM object will give you an almost complete wix document.

If you don't need the library available in the GAC (ie, globally available: MOST of the time you do not need this with your .NET assemblies anyway - you've probably done something wrong at this point if it's not intended to be a shared library) you will want to make sure to update the CodeBase registry key to be set to [#ComponentName]. If you ARE planning on installing it to the GAC (eg, you've made some new awesome common library that everyone will want to use) you must remove this entry, and add two new attributes to the File element: Assembly and KeyPath. Assembly should be set to ".net" and KeyPath should be set to "yes".

However, some environments (especially anything with managed memory such as scripting languages) will need access to the Typelib as well. Make sure to run heat on your typelib and include it. heat will generate all the needed registry keys. How cool is that?

You have to use the Print to a New PDF option using the PDF printer. Once in the dialog box, set the page scaling to 100% and set your page size. Once you do that, your new PDF will be uniform in page sizes.

Can anyone tell me why json_encode adds slashes?

Forward slash characters can cause issues (when preceded by a < it triggers the SGML rules for "end of script element") when embedded in an HTML script element. They are escaped as a precaution.

Because when I try do use jQuery.parseJSON(response); in my js script, it returns null. So my guess it has something to do with the slashes.

It doesn't. In JSON "/" and "\/" are equivalent.

The JSON you list in the question is valid (you can test it with jsonlint). Your problem is likely to do with what happens to it between json_encode and parseJSON.

It's usually describes as for optional add-on software packagessource, or anything that isn't part of the base system. Only some distributions use it, others simply use /usr/local.

You can do it with regular JavaScript this way:

document.getElementById('h1_id').innerHTML = 'h1 content here';

Here is the doc for getElementById and the innerHTML property.

The innerHTML property description:

A DOMString containing the HTML serialization of the element's descendants. Setting the value of innerHTML removes all of the element's descendants and replaces them with nodes constructed by parsing the HTML given in the string htmlString.

search all not (word characters || space):

str.replace(/[^\w ]/, '')

Instead of listening to the scroll event, using Intersection Observer is the inexpensive one for checking if the last element was visible on the viewport (that's mean user was scrolled to the bottom). It also supported for IE7 with the polyfill.

var observer = new IntersectionObserver(function(entries){_x000D_
   if(entries[0].isIntersecting === true)_x000D_
      console.log("Scrolled to the bottom");_x000D_
   else_x000D_
      console.log("Not on the bottom");_x000D_
}, {_x000D_
   root:document.querySelector('#scrollContainer'),_x000D_
   threshold:1 // Trigger only when whole element was visible_x000D_
});_x000D_
_x000D_
observer.observe(document.querySelector('#scrollContainer').lastElementChild);

#scrollContainer{_x000D_
  height: 100px;_x000D_
  overflow: hidden scroll;_x000D_
}

<div id="scrollContainer">_x000D_
  <div>Item 1</div>_x000D_
  <div>Item 2</div>_x000D_
  <div>Item 3</div>_x000D_
  <div>Item 4</div>_x000D_
  <div>Item 5</div>_x000D_
  <div>Item 6</div>_x000D_
  <div>Item 7</div>_x000D_
  <div>Item 8</div>_x000D_
  <div>Item 9</div>_x000D_
  <div>Item 10</div>_x000D_
</div>

In my case, I needed to find the directory name of a full path (of a directory) so I simply did:

var dirName = path.Split('\\').Last();

Use controller.controller_name

In the Rails Guides, it says:

The params hash will always contain the :controller and :action keys, but you should use the methods controller_name and action_name instead to access these values

ActionController Parameters

So let's say you have a CSS class active , that should be inserted in any link whose page is currently open (maybe so that you can style differently) . If you have a static_pages controller with an about action, you can then highlight the link like so in your view:

<li>
  <a class='button <% if controller.controller_name == "static_pages" && controller.action_name == "about" %>active<%end%>' href="/about">
      About Us
  </a>
</li>

You can do it by listening to phone call events . You do it by having a BroadcastReceiver to PHONE_STATE and to NEW_OUTGOING_CALL. You find there what is the phone number.

Then when you decide to end the call, this is a bit tricky, because only from Android P it's guaranteed to work. Check here.

You can accomplish this (if I understand what you are trying to do) using dynamic SQL.

The trick is that you need to create a string containing the SQL statement. That's because the tablename has to specified in the actual SQL text, when you execute the statement. The table references and column references can't be supplied as parameters, those have to appear in the SQL text.

So you can use something like this approach:

SET @stmt = 'INSERT INTO @tmpTbl1 SELECT ' + @KeyValue 
    + ' AS fld1 FROM tbl' + @KeyValue

EXEC (@stmt)

First, we create a SQL statement as a string. Given a @KeyValue of 'Foo', that would create a string containing:

'INSERT INTO @tmpTbl1 SELECT Foo AS fld1 FROM tblFoo'

At this point, it's just a string. But we can execute the contents of the string, as a dynamic SQL statement, using EXECUTE (or EXEC for short).

The old-school sp_executesql procedure is an alternative to EXEC, another way to execute dymamic SQL, which also allows you to pass parameters, rather than specifying all values as literals in the text of the statement.

FOLLOWUP

EBarr points out (correctly and importantly) that this approach is susceptible to SQL Injection.

Consider what would happen if @KeyValue contained the string:

'1 AS foo; DROP TABLE students; -- '

The string we would produce as a SQL statement would be:

'INSERT INTO @tmpTbl1 SELECT 1 AS foo; DROP TABLE students; -- AS fld1 ...'

When we EXECUTE that string as a SQL statement:

INSERT INTO @tmpTbl1 SELECT 1 AS foo;
DROP TABLE students;
-- AS fld1 FROM tbl1 AS foo; DROP ...

And it's not just a DROP TABLE that could be injected. Any SQL could be injected, and it might be much more subtle and even more nefarious. (The first attacks can be attempts to retreive information about tables and columns, followed by attempts to retrieve data (email addresses, account numbers, etc.)

One way to address this vulnerability is to validate the contents of @KeyValue, say it should contain only alphabetic and numeric characters (e.g. check for any characters not in those ranges using LIKE '%[^A-Za-z0-9]%'. If an illegal character is found, then reject the value, and exit without executing any SQL.

I suggest using pubnub. I tried using ServiceWorkers and PushNotification from the browser however, however when I tried it webviews did not support this.

Short story: links. Make use of something like:

    color: red;
    pointer-events: none;
    cursor: default;
    text-decoration: none;
}

<a href="red">Look, ma! Red!</a>

(HTML above for demonstration purposes)

And in your md source:

[Look, ma! Red!](red)

It means the path you input caused an error. In your LD_PRELOAD command, modify the path like the error tips:

You can try returning the variable you wish to inspect. E.g. I have this function:

--Contencates seperate date and time strings and converts to a datetime. Date should be in format 25.03.2012. Time as 9:18:25.
ALTER FUNCTION [dbo].[ufn_GetDateTime] (@date nvarchar(11), @time nvarchar(11))
RETURNS datetime
AS
BEGIN

        --select dbo.ufn_GetDateTime('25.03.2012.', '9:18:25')

    declare @datetime datetime

    declare @day_part nvarchar(3)
    declare @month_part nvarchar(3)
    declare @year_part nvarchar(5)

    declare @point_ix int

    set @point_ix = charindex('.', @date)
    set @day_part = substring(@date, 0, @point_ix)

    set @date = substring(@date, @point_ix, len(@date) - @point_ix)
    set @point_ix = charindex('.', @date)

    set @month_part = substring(@date, 0, @point_ix)

    set @date = substring(@date, @point_ix, len(@date) - @point_ix)
    set @point_ix = charindex('.', @date)

    set @year_part = substring(@date, 0, @point_ix)

    set @datetime = @month_part + @day_part  + @year_part + ' ' + @time

    return @datetime
END

When I run it.. I get: Msg 241, Level 16, State 1, Line 1 Conversion failed when converting date and/or time from character string.

Arghh!!

So, what do I do?

ALTER FUNCTION [dbo].[ufn_GetDateTime] (@date nvarchar(11), @time nvarchar(11))
RETURNS nvarchar(22)
AS
BEGIN

        --select dbo.ufn_GetDateTime('25.03.2012.', '9:18:25')

    declare @day_part nvarchar(3)
    declare @point_ix int

    set @point_ix = charindex('.', @date)
    set @day_part = substring(@date, 0, @point_ix)

    return @day_part
END

And I get '25'. So, I am off by one and so I change to..

set @day_part = substring(@date, 0, @point_ix + 1)

Voila! Now it works :)

When I wanted to use the standard XMLGregorianCalendar for my XML to object marshalling of DateTime in Java, I heard a lot of comments on how heavy weight and cumbersome it was to use it. I was trying to comtrol the XML fields in the xs:datetime structs to manage timezone, milliseconds, etc.

So I designed a utility to build an XMLGregorian calendar from a GregorianCalendar or java.util.Date.

Because of where I work I'm not allowed to share it online without legal, but here's an example of how a client uses it. It abstracts the details and filters some of the implementation of XMLGregorianCalendar that are less used for xs:datetime.

XMLGregorianCalendarBuilder builder = XMLGregorianCalendarBuilder.newInstance(jdkDate);
XMLGregorianCalendar xmlCalendar = builder.excludeMillis().excludeOffset().build();

Granted this pattern is more of a filter as it sets fields in the xmlCalendar as undefined so they are excluded, it still "builds" it. I've easily added other options to the builder to create an xs:date, and xs:time struct and also to manipulate timezone offsets when needed.

If you've ever seen code that creates and uses XMLGregorianCalendar, you would see how this made it much easier to manipulate.

It works for me:

if (isset($_POST['MyTextAreaName'])){
    $array=explode( "\r\n", $_POST['MyTextAreaName'] );

now, my $array will have all the lines I need

    for ($i = 0; $i <= count($array); $i++) 
    {
        echo (trim($array[$i]) . "<br/>");
    }

(make sure to close the if block with another curly brace)

}

If you are reading unicode escaped chars from a file, then you will have a tough time doing that because the string will be read literally along with an escape for the back slash:

my_file.txt

Blah blah...
Column delimiter=;
Word delimiter=\u0020 #This is just unicode for whitespace

.. more stuff

Here, when you read line 3 from the file the string/line will have:

"Word delimiter=\u0020 #This is just unicode for whitespace"

and the char[] in the string will show:

{...., '=', '\\', 'u', '0', '0', '2', '0', ' ', '#', 't', 'h', ...}

Commons StringUnescape will not unescape this for you (I tried unescapeXml()). You'll have to do it manually as described here.

So, the sub-string "\u0020" should become 1 single char '\u0020'

But if you are using this "\u0020" to do String.split("... ..... ..", columnDelimiterReadFromFile) which is really using regex internally, it will work directly because the string read from file was escaped and is perfect to use in the regex pattern!! (Confused?)

You have a class of the same name declared more than once. Maybe via multiple includes. When including other files you need to use something like

include_once "something.php";

to prevent multiple inclusions. It's very easy for this to happen, though not always obvious, since you could have a long chain of files being included by one another.

You can reset the mfrow parameter

par(mfrow=c(1,1))

If you are working in a browser that doesn't support tabindex="-1", you may be able to get away with just giving the things that need to be skipped a really high tab index. For example tabindex="500" basically moves the object's tab order to the end of the page.

I did this for a long data entry form with a button thrown in the middle of it. It's not a button people click very often so I didn't want them to accidentally tab to it and press enter. disabled wouldn't work because it's a button.

As variant, you can use radare2:

For details about how work in visual mode you can read here

Use

git apply patchfile

if possible.

patch -p1 < patchfile 

has potential side-effect.

git apply also handles file adds, deletes, and renames if they're described in the git diff format, which patch won't do. Finally, git apply is an "apply all or abort all" model where either everything is applied or nothing is, whereas patch can partially apply patch files, leaving your working directory in a weird state.

what about just store the output to the static table ? Like

-- SubProcedure: subProcedureName
---------------------------------
-- Save the value
DELETE lastValue_subProcedureName
INSERT INTO lastValue_subProcedureName (Value)
SELECT @Value
-- Return the value
SELECT @Value

-- Procedure
--------------------------------------------
-- get last value of subProcedureName
SELECT Value FROM lastValue_subProcedureName

its not ideal, but its so simple and you don't need to rewrite everything.

UPDATE: the previous solution does not work well with parallel queries (async and multiuser accessing) therefore now Iam using temp tables

-- A local temporary table created in a stored procedure is dropped automatically when the stored procedure is finished. 
-- The table can be referenced by any nested stored procedures executed by the stored procedure that created the table. 
-- The table cannot be referenced by the process that called the stored procedure that created the table.
IF OBJECT_ID('tempdb..#lastValue_spGetData') IS NULL
CREATE TABLE #lastValue_spGetData (Value INT)

-- trigger stored procedure with special silent parameter
EXEC dbo.spGetData 1 --silent mode parameter

nested spGetData stored procedure content

-- Save the output if temporary table exists.
IF OBJECT_ID('tempdb..#lastValue_spGetData') IS NOT NULL
BEGIN
    DELETE #lastValue_spGetData
    INSERT INTO #lastValue_spGetData(Value)
    SELECT Col1 FROM dbo.Table1
END

 -- stored procedure return
 IF @silentMode = 0
 SELECT Col1 FROM dbo.Table1

Pattern p = Pattern.compile("tom"); //the regular-expression pattern
Matcher m = p.matcher("(bob)(tom)(harry)"); //The data to find matches with

while (m.find()) {
    //do something???
}   

Use regex to find a match maybe?

Or create an array

 String[] a = new String[]{
        "tom",
        "bob",
        "harry"
 };

 if(a.contains(stringtomatch)){
     //do something
 }

My solution:

File jarToAdd = new File("/path/to/file");

new URLClassLoader(((URLClassLoader) ClassLoader.getSystemClassLoader()).getURLs()) {
    @Override
    public void addURL(URL url) {
         super.addURL(url);
    }
}.addURL(jarToAdd.toURI().toURL());

For whoever still looking for a copy + paste solution in nano editor

To select text

• ctrl+6
• Use arrow to move the cursor to where you want the mark to end

Note: If you want to copy the whole line, no need to mark just move the cursor to the line

To copy:

• Press alt + 6

To paste:

• Press ctrl + U

Reference

try this:

.button input, .button a {
//css here
}

That will apply the style to all a tags nested inside of <p class="button"></p>

It can be done by simply iterating across the main array and check whether other array contains any of the target element or not.

Try this:

function Check(A) {
    var myarr = ["apple", "banana", "orange"];
    var i, j;
    var totalmatches = 0;
    for (i = 0; i < myarr.length; i++) {
        for (j = 0; j < A.length; ++j) {
            if (myarr[i] == A[j]) {

                totalmatches++;

            }

        }
    }
    if (totalmatches > 0) {
        return true;
    } else {
        return false;
    }
}
var fruits1 = new Array("apple", "grape");
alert(Check(fruits1));

var fruits2 = new Array("apple", "banana", "pineapple");
alert(Check(fruits2));

var fruits3 = new Array("grape", "pineapple");
alert(Check(fruits3));

DEMO at JSFIDDLE

<form onsubmit="alert(this.submitted); return false;">
    <input onclick="this.form.submitted=this.value;" type="submit" value="Yes" />
    <input onclick="this.form.submitted=this.value;" type="submit" value="No" />
</form>

jsfiddle for the same

Use textContent instead of value to set the button text.

Typically the value attribute is used to associate a value with the button when it's submitted as form data.

Note that while it's possible to set the button text with innerHTML, using textContext should be preferred because it's more performant and it can prevent cross-site scripting attacks as its value is not parsed as HTML.

JS:

var b = document.createElement('button');
b.setAttribute('content', 'test content');
b.setAttribute('class', 'btn');  
b.textContent = 'test value';

var wrapper = document.getElementById("divWrapper");
wrapper.appendChild(b);

Produces this in the DOM:

<div id="divWrapper">
    <button content="test content" class="btn">test value</button>
</div>

Storyboard doesn't work for me all the time even after trying all the solution here

So it is always perfect answer is using the code, Just create IBOutlet instance of the UIView and add the properties

Short answer :

layer.cornerRadius = 10
layer.borderWidth = 1
layer.borderColor = UIColor.blue.cgColor

Long answer :

Rounded Corners of UIView/UIButton etc

customUIView.layer.cornerRadius = 10

Border Thickness

pcustomUIView.layer.borderWidth = 2

Border Color

customUIView.layer.borderColor = UIColor.blue.cgColor

Thanks, I found your answers convincing but in my case, I must use the T properties:

log(n!) = T(n·log n) =>  log(n!) = O(n log n) and log(n!) = O(n log n)

to verify the problem I found this web, where you have all the process explained: http://www.mcs.sdsmt.edu/ecorwin/cs372/handouts/theta_n_factorial.htm

MySQL Workbench 8.0 Update

Based on Gunther's answer, it seems like in code_editor.xml they're planning to enable a dark mode at some point down the road. What was once fore-color has now been split into fore-color-light and fore-color-dark. Likewise with back-color.

Here's how to get a dark editor (not whole application theme) based on the Monokai colours provided graciously by elMestre:

<!--

    if(lower > upper) return 0;
    if(lower == upper) return lower;
    int difference = upper - lower;
    int start = getRandomInt();

    //nonneg int in the range 0..difference - 1
    start = Math.abs(start) % (difference+1);

    start += lower;
    return start;
}

    List<Integer> a= new ArrayList();

    int i;
    int c=0;
    for(;;) {
        c++;
        i= getRandomInt(100, 500000);
        if(!(a.contains(i))) {
            a.add(i);
            if (c == 10000) break;
            System.out.println(i);
        }


    }

    for(int rand : a) {
        System.out.println(rand);
    }



}

Get Random number Returns a random integer x satisfying lower <= x <= upper. If lower > upper, returns 0. @param lower @param upper @return

In the main method I created list then i check if the random number exist on the list if it doesn't exist i will add the random number to the list

$('.checkall').change(function() {
    var checkboxes = $(this).closest('table').find('td').find(':checkbox');
    if($(this).is(':checked')) {
        checkboxes.attr('checked', 'checked');
    } else {
        checkboxes.removeAttr('checked');
    }
});

Type "set" and you will get a list of all the current variables. If you want something to persist put it in ~/.bashrc or ~/.bash_profile (if you're using bash)

Besides the solution of m79lkm above, my 2 cents on this topic is not to directly pipe the result in gzip but first dump it as a .sql file, and then gzip it. (Use && instead of | )

The dump itself will be faster. (for what I tested it was double as fast)

Otherwise you tables will be locked longer and the downtime/slow-responding of your application can bother the users. The mysqldump command is taking a lot of resources from your server.

So I would go for "&& gzip" instead of "| gzip"

Important: check for free disk space first with df -h since you will need more then piping | gzip.

mysqldump -u user -p[user_password] [database_name] > dumpfilename.sql && gzip dumpfilename.sql

-> which will also result in 1 file called dumpfilename.sql.gz

Furthermore the option --single-transaction prevents the tables being locked but still result in a solid backup. So you might consider to use that option. See docs here

mysqldump --single-transaction -u user -p[user_password] [database_name] > dumpfilename.sql && gzip dumpfilename.sql

I'm not sure why previous answers haven't suggested that the original poster set up a shell profile (bashrc, .tcshrc, etc.) that executed their commands automatically every time they log in on the server side.

The quest that brought me to this page for help was a bit different -- I wanted multiple PuTTY shortcuts for the same host that would execute different startup commands.

I came up with two solutions, both of which worked:

(background) I have a folder with a variety of PuTTY shortcuts, each with the "target" property in the shortcut tab looking something like:

"C:\Program Files (x86)\PuTTY\putty.exe" -load host01

with each load corresponding to a PuTTY profile I'd saved (with different hosts in the "Session" tab). (Mostly they only differ in color schemes -- I like to have each group of related tasks share a color scheme in the terminal window, with critical tasks, like logging in as root on a production system, performed only in distinctly colored windows.)

The folder's Windows properties are set to very clean and stripped down -- it functions as a small console with shortcut icons for each of my frequent remote PuTTY and RDP connections.

(solution 1) As mentioned in other answers the -m switch is used to configure a script on the Windows side to run, the -t switch is used to stay connected, but I found that it was order-sensitive if I wanted to get it to run without exiting

What I finally got to work after a lot of trial and error was:

(shortcut target field):

"C:\Program Files (x86)\PuTTY\putty.exe" -t -load "SSH Proxy" -m "C:\Users\[me]\Documents\hello-world-bash.txt"

where the file being executed looked like

echo "Hello, World!"
echo ""
export PUTTYVAR=PROXY
/usr/local/bin/bash

(no semicolons needed)

This runs the scripted command (in my case just printing "Hello, world" on the terminal) and sets a variable that my remote session can interact with.

Note for debugging: when you run PuTTY it loads the -m script, if you edit the script you need to re-launch PuTTY instead of just restarting the session.

(solution 2) This method feels a lot cleaner, as the brains are on the remote Unix side instead of the local Windows side:

From Putty master session (not "edit settings" from existing session) load a saved config and in the SSH tab set remote command to:

export PUTTYVAR=GREEN; bash -l

Then, in my .bashrc, I have a section that performs different actions based on that variable:

case ${PUTTYVAR} in
  "")
    echo "" 
    ;;
  "PROXY")
    # this is the session config with all the SSH tunnels defined in it
    echo "";
    echo "Special window just for holding tunnels open." ;
    echo "";
    PROMPT_COMMAND='echo -ne "\033]0;Proxy Session @master01\$\007"'
    alias temppass="ssh keyholder.example.com makeonetimepassword"
    alias | grep temppass
    ;;
  "GREEN")
    echo "";
    echo "It's not easy being green"
    ;;
  "GRAY")
    echo ""
    echo "The gray ghost"
    ;;
  *)
    echo "";
    echo "Unknown PUTTYVAR setting ${PUTTYVAR}"
    ;;
esac

(solution 3, untried)

It should also be possible to have bash skip my .bashrc and execute a different startup script, by putting this in the PuTTY SSH command field:

bash --rcfile .bashrc_variant -l 

Quoting the iPhone OS Technology Overview:

iPhone OS provides support for full-screen video playback through the Media Player framework (MediaPlayer.framework). This framework supports the playback of movie files with the .mov, .mp4, .m4v, and .3gp filename extensions and using the following compression standards:

• H.264 video, up to 1.5 Mbps, 640 by 480 pixels, 30 frames per second, Low-Complexity version of the H.264 Baseline Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
• H.264 video, up to 768 Kbps, 320 by 240 pixels, 30 frames per second, Baseline Profile up to Level 1.3 with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
• MPEG-4 video, up to 2.5 Mbps, 640 by 480 pixels, 30 frames per second, Simple Profile with AAC-LC audio up to 160 Kbps, 48kHz, stereo audio in .m4v, .mp4, and .mov file formats
• Numerous audio formats, including the ones listed in “Audio Technologies”

For information about the classes of the Media Player framework, see Media Player Framework Reference.

Your code is in the <head> => runs before the elements are rendered, so document.getElementById('compute'); returns null, as MDN promise...

element = document.getElementById(id);
element is a reference to an Element object, or null if an element with the specified ID is not in the document.

MDN

Solutions:

1. Put the scripts in the bottom of the page.
2. Call the attach code in the load event.
3. Use jQuery library and it's DOM ready event.

What is the jQuery ready event and why is it needed?
(why no just JavaScript's load event):

While JavaScript provides the load event for executing code when a page is rendered, this event does not get triggered until all assets such as images have been completely received. In most cases, the script can be run as soon as the DOM hierarchy has been fully constructed. The handler passed to .ready() is guaranteed to be executed after the DOM is ready, so this is usually the best place to attach all other event handlers...

TLDR Summary

In modern MongoDB releases you can brute force this with $slice just off the basic aggregation result. For "large" results, run parallel queries instead for each grouping ( a demonstration listing is at the end of the answer ), or wait for SERVER-9377 to resolve, which would allow a "limit" to the number of items to $push to an array.

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 },
    { "$project": {
        "books": { "$slice": [ "$books", 2 ] },
        "count": 1
    }}
])

MongoDB 3.6 Preview

Still not resolving SERVER-9377, but in this release $lookup allows a new "non-correlated" option which takes an "pipeline" expression as an argument instead of the "localFields" and "foreignFields" options. This then allows a "self-join" with another pipeline expression, in which we can apply $limit in order to return the "top-n" results.

db.books.aggregate([
  { "$group": {
    "_id": "$addr",
    "count": { "$sum": 1 }
  }},
  { "$sort": { "count": -1 } },
  { "$limit": 2 },
  { "$lookup": {
    "from": "books",
    "let": {
      "addr": "$_id"
    },
    "pipeline": [
      { "$match": { 
        "$expr": { "$eq": [ "$addr", "$$addr"] }
      }},
      { "$group": {
        "_id": "$book",
        "count": { "$sum": 1 }
      }},
      { "$sort": { "count": -1  } },
      { "$limit": 2 }
    ],
    "as": "books"
  }}
])

The other addition here is of course the ability to interpolate the variable through $expr using $match to select the matching items in the "join", but the general premise is a "pipeline within a pipeline" where the inner content can be filtered by matches from the parent. Since they are both "pipelines" themselves we can $limit each result separately.

This would be the next best option to running parallel queries, and actually would be better if the $match were allowed and able to use an index in the "sub-pipeline" processing. So which is does not use the "limit to $push" as the referenced issue asks, it actually delivers something that should work better.

Original Content

You seem have stumbled upon the top "N" problem. In a way your problem is fairly easy to solve though not with the exact limiting that you ask for:

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 }
])

Now that will give you a result like this:

{
    "result" : [
            {
                    "_id" : "address1",
                    "books" : [
                            {
                                    "book" : "book4",
                                    "count" : 1
                            },
                            {
                                    "book" : "book5",
                                    "count" : 1
                            },
                            {
                                    "book" : "book1",
                                    "count" : 3
                            }
                    ],
                    "count" : 5
            },
            {
                    "_id" : "address2",
                    "books" : [
                            {
                                    "book" : "book5",
                                    "count" : 1
                            },
                            {
                                    "book" : "book1",
                                    "count" : 2
                            }
                    ],
                    "count" : 3
            }
    ],
    "ok" : 1
}

So this differs from what you are asking in that, while we do get the top results for the address values the underlying "books" selection is not limited to only a required amount of results.

This turns out to be very difficult to do, but it can be done though the complexity just increases with the number of items you need to match. To keep it simple we can keep this at 2 matches at most:

db.books.aggregate([
    { "$group": {
        "_id": {
            "addr": "$addr",
            "book": "$book"
        },
        "bookCount": { "$sum": 1 }
    }},
    { "$group": {
        "_id": "$_id.addr",
        "books": { 
            "$push": { 
                "book": "$_id.book",
                "count": "$bookCount"
            },
        },
        "count": { "$sum": "$bookCount" }
    }},
    { "$sort": { "count": -1 } },
    { "$limit": 2 },
    { "$unwind": "$books" },
    { "$sort": { "count": 1, "books.count": -1 } },
    { "$group": {
        "_id": "$_id",
        "books": { "$push": "$books" },
        "count": { "$first": "$count" }
    }},
    { "$project": {
        "_id": {
            "_id": "$_id",
            "books": "$books",
            "count": "$count"
        },
        "newBooks": "$books"
    }},
    { "$unwind": "$newBooks" },
    { "$group": {
      "_id": "$_id",
      "num1": { "$first": "$newBooks" }
    }},
    { "$project": {
        "_id": "$_id",
        "newBooks": "$_id.books",
        "num1": 1
    }},
    { "$unwind": "$newBooks" },
    { "$project": {
        "_id": "$_id",
        "num1": 1,
        "newBooks": 1,
        "seen": { "$eq": [
            "$num1",
            "$newBooks"
        ]}
    }},
    { "$match": { "seen": false } },
    { "$group":{
        "_id": "$_id._id",
        "num1": { "$first": "$num1" },
        "num2": { "$first": "$newBooks" },
        "count": { "$first": "$_id.count" }
    }},
    { "$project": {
        "num1": 1,
        "num2": 1,
        "count": 1,
        "type": { "$cond": [ 1, [true,false],0 ] }
    }},
    { "$unwind": "$type" },
    { "$project": {
        "books": { "$cond": [
            "$type",
            "$num1",
            "$num2"
        ]},
        "count": 1
    }},
    { "$group": {
        "_id": "$_id",
        "count": { "$first": "$count" },
        "books": { "$push": "$books" }
    }},
    { "$sort": { "count": -1 } }
])

So that will actually give you the top 2 "books" from the top two "address" entries.

But for my money, stay with the first form and then simply "slice" the elements of the array that are returned to take the first "N" elements.

Demonstration Code

The demonstration code is appropriate for usage with current LTS versions of NodeJS from v8.x and v10.x releases. That's mostly for the async/await syntax, but there is nothing really within the general flow that has any such restriction, and adapts with little alteration to plain promises or even back to plain callback implementation.

index.js

const { MongoClient } = require('mongodb');
const fs = require('mz/fs');

const uri = 'mongodb://localhost:27017';

In Python 3.4+, you can use the new pathlib package:

from pathlib import Path
for path in Path('.').iterdir():
    print(path)

Path.iterdir() returns an iterator, which can be easily turned into a list:

contents = list(Path('.').iterdir())

Reformat affects the whole source code and may rebreak your lines, while Correct Indentation only affects the whitespace at the beginning of the lines.

The cleanest approach is to copy the list and then insert the object into the copy. On Python 3 this can be done via list.copy:

new = old.copy()
new.insert(index, value)

On Python 2 copying the list can be achieved via new = old[:] (this also works on Python 3).

In terms of performance there is no difference to other proposed methods:

$ python --version
Python 3.8.1
$ python -m timeit -s "a = list(range(1000))" "b = a.copy(); b.insert(500, 3)"
100000 loops, best of 5: 2.84 µsec per loop
$ python -m timeit -s "a = list(range(1000))" "b = a.copy(); b[500:500] = (3,)"
100000 loops, best of 5: 2.76 µsec per loop

Same problem with me. I solved this by adding @ before connection string (C# has a thing called 'String Literals') like so:

SqlConnection sconnection = new SqlConnection(@"Data Source=(Localdb)\v11.0; Initial Catalog=Mydatabase;Integrated Security=True");

sconnection.Open();

Much simpler using only SimpleDateFormat, without passing all the parameters individual:

    String FORMATER = "yyyy-MM-dd'T'HH:mm:ss'Z'";

    DateFormat format = new SimpleDateFormat(FORMATER);

    Date date = new Date();
    XMLGregorianCalendar gDateFormatted =
        DatatypeFactory.newInstance().newXMLGregorianCalendar(format.format(date));

Full example here.

Note: This is working only to remove the last 2 fields: milliseconds and timezone or to remove the entire time component using formatter yyyy-MM-dd.

I'm not really too clear what you are asking, but using the -f command line option just specifies a file - it doesn't tell make to change directories. If you want to do the work in another directory, you need to cd to the directory:

clean:
    cd gtest-1.4.0 && $(MAKE) clean

Note that each line in Makefile runs in a separate shell, so there is no need to change the directory back.

You can use belw code for show and hide bootstrap model.

$('#my-model').on('shown.bs.modal', function (e) {
  // do something here...
})

and if you want to hide model then you can use below code.

$('#my-model').on('hidden.bs.modal', function() {
    // do something here...
});

I hope this answer is useful for your project.

for common use "forget normal loops" and use this combination of "setInterval" includes "setTimeOut"s: like this (from my real tasks).

        function iAsk(lvl){
            var i=0;
            var intr =setInterval(function(){ // start the loop 
                i++; // increment it
                if(i>lvl){ // check if the end round reached.
                    clearInterval(intr);
                    return;
                }
                setTimeout(function(){
                    $(".imag").prop("src",pPng); // do first bla bla bla after 50 millisecond
                },50);
                setTimeout(function(){
                     // do another bla bla bla after 100 millisecond.
                    seq[i-1]=(Math.ceil(Math.random()*4)).toString();
                    $("#hh").after('<br>'+i + ' : rand= '+(Math.ceil(Math.random()*4)).toString()+' > '+seq[i-1]);
                    $("#d"+seq[i-1]).prop("src",pGif);
                    var d =document.getElementById('aud');
                    d.play();                   
                },100);
                setTimeout(function(){
                    // keep adding bla bla bla till you done :)
                    $("#d"+seq[i-1]).prop("src",pPng);
                },900);
            },1000); // loop waiting time must be >= 900 (biggest timeOut for inside actions)
        }

PS: Understand that the real behavior of (setTimeOut): they all will start in same time "the three bla bla bla will start counting down in the same moment" so make a different timeout to arrange the execution.

PS 2: the example for timing loop, but for a reaction loops you can use events, promise async await ..

Use a labeled break as an alternative to goto.

Descending order using underscore can be done by multiplying the return value by -1.

//Ascending Order:
_.sortBy([2, 3, 1], function(num){
    return num;
}); // [1, 2, 3]


//Descending Order:
_.sortBy([2, 3, 1], function(num){
    return num * -1;
}); // [3, 2, 1]

If you're sorting by strings not numbers, you can use the charCodeAt() method to get the unicode value.

//Descending Order Strings:
_.sortBy(['a', 'b', 'c'], function(s){ 
    return s.charCodeAt() * -1;
});

CSS code:

.hide{
display:none;
}

.show{
display:block;
}

Html code:

<button onclick="block_none()">Check Availability</button>

Javascript Code:

function block_none(){
 document.getElementById('hidden-div').classList.add('show');
document.getElementById('button-id').classList.add('hide');
}

The classical answer that works in almost every environment is

SELECT ID, Name, blah, blah
FROM TableB TB
LEFT JOIN TableA TA
ON TB.ID=TA.ID
WHERE TA.ID IS NULL

sometimes NOT EXISTS may be not implemented (not working).

This validates date like dd-mm-yyyy

([0-2][0-9]|(3)[0-1])(\-)(((0)[0-9])|((1)[0-2]))(\-)([0-9][0-9][0-9][0-9])

This can use with javascript like angular reactive forms

You can do the same in python by simply importing the second file, code at the top level will run when imported. I'd suggest this is messy at best, and not a good programming practice. You would be better off organizing your code into modules

Example:

F1.py:

print "Hello, "
import f2

F2.py:

print "World!"

When run:

python ./f1.py
Hello, 
World!

Edit to clarify: The part I was suggesting was "messy" is using the import statement only for the side effect of generating output, not the creation of separate source files.

as for react-router-dom 4.x.x (https://www.npmjs.com/package/react-router-dom) you can pass params to the component to route to via:

<Route path="/ideas/:value" component ={CreateIdeaView} />

linking via (considering testValue prop is passed to the corresponding component (e.g. the above App component) rendering the link)

<Link to={`/ideas/${ this.props.testValue }`}>Create Idea</Link>

passing props to your component constructor the value param will be available via

props.match.params.value

Note : Use it if calculating / adding days from current date.

Be aware: this answer has issues (see comments)

var myDate = new Date();
myDate.setDate(myDate.getDate() + AddDaysHere);

It should be like

var newDate = new Date(date.setTime( date.getTime() + days * 86400000 ));

Why using selector as the root tag? selector is used for applying multiple alternate drawables for different states of the view, so in this case, there is no need for selector.

Try the following code.

<?xml version="1.0" encoding="utf-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android">

    <!-- Background Color -->
    <solid android:color="#ffffff" />

    <!-- Border Color -->
    <stroke android:width="1dp" android:color="#ff9900" />

    <!-- Round Corners -->
    <corners android:radius="5dp" />

</shape>

Also It's worth mentioning that all color entries support alpha channel as well, meaning that you can have transparent or semi-transparent colors. For example #RRGGBBAA.

I use the way shown below. It submits everything like files.

$(document).on("submit", "form", function(event)
{
    event.preventDefault();

    var url  = $(this).attr("action");
    $.ajax({
        url: url,
        type: 'POST',
        dataType: "JSON",
        data: new FormData(this),
        processData: false,
        contentType: false,
        success: function (data, status)
        {

        },
        error: function (xhr, desc, err)
        {
            console.log("error");
        }
    });
});

Find the latest version of chromedriver here. Once downloaded, unzip it at the root of your Python installation, e.g., C:/Program Files/Python-3.5, and that's it.

You don't even need to specify the path anywhere and/or add chromedriver to your path or the like. I just did it on a clean Python installation and that works.

I have tested successfully with simple code below

USE [master]
GO
ALTER DATABASE [YourDatabaseName] SET SINGLE_USER WITH ROLLBACK IMMEDIATE
GO

The first thing comes to my mind is: this is a good place to use Binary search (inspired by this great tutorials.)

To find the square root of vaule ,we are searching the number in (1..value) where the predictor is true for the first time. The predictor we are choosing is number * number - value > 0.00001.

double square_root_of(double value)
{
     assert(value >= 1);
     double lo = 1.0;
     double hi = value;

     while( hi - lo > 0.00001)
     {
          double mid = lo + (hi - lo) / 2 ;
          std::cout << lo << "," << hi << "," << mid << std::endl;
          if( mid * mid - value > 0.00001)    //this is the predictors we are using 
          {
              hi = mid;
          } else {
              lo = mid;
          }

     }

    return lo;
 }

As stated in comments below, you can use also the SET ROWCOUNT clause, but just for SQL Server 2014 and older.

SET ROWCOUNT 10

UPDATE messages
SET status = 10 
WHERE status = 0 

SET ROWCOUNT 0

More info: http://msdn.microsoft.com/en-us/library/ms188774.aspx

Or with a temp table

DECLARE @t TABLE (id INT)
INSERT @t (id)
SELECT TOP 10 id
FROM messages
WHERE status = 0
ORDER BY priority DESC

UPDATE messages
SET status = 10
WHERE id IN (SELECT id FROM @t)

If your using ASP.Net 5 (now known as ASP.Net Core v1) ensure in your project.json "commands" section for each site you are hosting that the Kestrel proxy listening port differs between sites, otherwise one site will work but the other will return a 504 gateway timeout.

 "commands": {
    "web": "Microsoft.AspNet.Server.Kestrel --server.urls http://localhost:5090"
  },

all Values is always taken with .val().

see the code bellow:

var message = $('#message').val();

@AnandaMahto has addressed why you're getting these results and provided the clearest way to get what you want. But another option would be to use identical instead of ==.

test$ID <- ifelse(is.na(test$time) | sapply(as.character(test$type), identical, "A"), NA, "1")

Or use isTRUE:

test$ID <- ifelse(is.na(test$time) | Vectorize(isTRUE)(test$type == "A"), NA, "1")

Install x32 version nodejs instead of x64 version (even on 64-bit windows machine).

Abstraction- Abstraction in simple words can be said as a way out in which the user is kept away from the complex details or detailed working of some system. You can also assume it as a simple way to solve any problem at the design and interface level.

You can say the only purpose of abstraction is to hide the details that can confuse a user. So for simplification purposes, we can use abstraction. Abstraction is also a concept of object-oriented programming. It hides the actual data and only shows the necessary information. For example, in an ATM machine, you are not aware that how it works internally. Only you are concerned to use the ATM interface. So that can be considered as a type of abstraction process.

Encapsulation- Encapsulation is also part of object-oriented programming. In this, all you have to do is to wrap up the data and code together so that they can work as a single unit. it works at the implementation level. it also improves the application Maintainance.

Encapsulation focuses on the process which will save information. Here you have to protect your data from external use.

if(strstr(sent, word) != NULL) {
    /* ... */
}

Note that strstr returns a pointer to the start of the word in sent if the word word is found.

If you use axios it can help you

$('#dialog').draggable({ handle: "#tblOverlay" , scroll: false });

    // Pop up Window 
          <div id="dialog">
                        <table  id="tblOverlay">
                            <tr><td></td></tr>
                         <table>
           </div>

Options:

1. handle : Avoids the sticky scroll bar issue. Sometimes your mouse pointer will stick to the popup window while dragging.
2. scroll : Prevent popup window to go beyond parent page or out of current screen.

Make sure to target x86 on your project in Visual Studio. This should fix your trouble.

use below statement if safe_mode is off

set_time_limit(0);

No other "addClass" methods worked for me when adding a class to an 'a' element on menu except this one:

$(function () {
        var url = window.location.pathname,
    urlRegExp = new RegExp(url.replace(/\/$/, '') + "$");  
        $('a').each(function () {
                            if (urlRegExp.test(this.href.replace(/\/$/, ''))) {
                $(this).addClass('active');
            }
        });
    });

This took me four hours to find it.

Instead of using width (which is a suggestion when using flexbox), you could use flex: 0 0 230px; which means:

• 0 = don't grow (shorthand for flex-grow)
• 0 = don't shrink (shorthand for flex-shrink)
• 230px = start at 230px (shorthand for flex-basis)

which means: always be 230px.

See fiddle, thanks @TylerH

Oh, and you don't need the justify-content and align-items here.

img {
    max-width: 100%;
}
#container {
    display: flex;
    x-justify-content: space-around;
    x-align-items: stretch;
    max-width: 1200px;
}
.column.left {
    width: 230px;
    flex: 0 0 230px;
}
.column.right {
    width: 230px;
    flex: 0 0 230px;
    border-left: 1px solid #eee;
}
.column.center {
    border-left: 1px solid #eee;
}

I don't know if it's good practice, but I used to use this:

($a=<F>);

Yes you can use .is(':visible') in jquery. But while the code is running under the safari browser .is(':visible') is won't work.

So please use the below code

if( $(".example").offset().top > 0 )

The above line will work both IE as well as safari also.

Use the Apache XMLSerializer

In Python 3 there is valid reason to use print over sys.stdout.write, but this reason can also be turned into a reason to use sys.stdout.write instead.

This reason is that, now print is a function in Python 3, you can override this. So you can use print everywhere in a simple script and decide those print statements need to write to stderr instead. You can now just redefine the print function, you could even change the print function global by changing it using the builtins module. Off course with file.write you can specify what file is, but with overwriting print you can also redefine the line separator, or argument separator.

The other way around is. Maybe you are absolutely certain you write to stdout, but also know you are going to change print to something else, you can decide to use sys.stdout.write, and use print for error log or something else.

So, what you use depends on how you intend to use it. print is more flexible, but that can be a reason to use and to not use it. I would still opt for flexibility instead, and choose print. Another reason to use print instead is familiarity. More people will now what you mean by print and less know sys.stdout.write.

Watch out for Bootstrap! Bootstrap will override .fa classes. If you're bringing in both packages separately thinking "I'll use Bootstrap for responsive block handling and Font-Awesome for icons", you need to address the .fa classes inside Bootstrap so they don't interfere with Font-Awesome's stand-alone implementation.

eg: font-family 'FontAwesome' in Bootstrap will interfere with font-family 'Font Awesome 5 Free' in Font-Awesome and you will get a white box instead of the icon you want.

There may be cleaner ways of handling this, but if you've gone down the checklist trying to fix the "white box" issue and still can't figure it out (like I did), this may be the answer you're looking for.

Very, VERY simple idea, but you can modify it accordingly. This isn't set up to look good, only to provide the idea. Hope it helps.

CSS:

ul {
    width: 50px;
    height: 20px;
    border: 1px solid black;
    display: block;

}

li {
    padding: 5px 0px;
    width: 50px;
    display: none;

}

HTML:

<ul id="customComboBox">
&nbsp
    <li>Test</li>
    <li>Test 2</li>
    <li>Test 3</li>
</ul>

Script:

$(document).ready(function(){
    $("#customComboBox").click(function(){
        $("li").toggle("slow");
    });
});

Here is another option.

os.scandir(path='.')

It returns an iterator of os.DirEntry objects corresponding to the entries (along with file attribute information) in the directory given by path.

Example:

with os.scandir(path) as it:
    for entry in it:
        if not entry.name.startswith('.'):
            print(entry.name)

Using scandir() instead of listdir() can significantly increase the performance of code that also needs file type or file attribute information, because os.DirEntry objects expose this information if the operating system provides it when scanning a directory. All os.DirEntry methods may perform a system call, but is_dir() and is_file() usually only require a system call for symbolic links; os.DirEntry.stat() always requires a system call on Unix but only requires one for symbolic links on Windows.

I think you should re-format your code a bit:

#!/bin/bash
if [ ! -d /home/mlzboy/b2c2/shared/db ]; then
    mkdir -p /home/mlzboy/b2c2/shared/db;
fi;

Researching this topic myself and having read the answers I recommend using the path.py library since it provides a context manager for changing the current working directory.

You then have something like

import path
if path.Path('../lib').isdir():
    with path.Path('..'):
        import lib

Although, you might just omit the isdir statement.

Here I'll add print statements to make it easy to follow what's happening

import path
import pandas

print(path.Path.getcwd())
print(path.Path('../lib').isdir())
if path.Path('../lib').isdir():
    with path.Path('..'):
        print(path.Path.getcwd())
        import lib
        print('Success!')
print(path.Path.getcwd())

which outputs in this example (where lib is at /home/jovyan/shared/notebooks/by-team/data-vis/demos/lib):

/home/jovyan/shared/notebooks/by-team/data-vis/demos/custom-chart
/home/jovyan/shared/notebooks/by-team/data-vis/demos
/home/jovyan/shared/notebooks/by-team/data-vis/demos/custom-chart

Since the solution uses a context manager, you are guaranteed to go back to your previous working directory, no matter what state your kernel was in before the cell and no matter what exceptions are thrown by importing your library code.

As answered in other posts, you have two different options for different platforms. What I do is:

document.addEventListener('deviceready', onDeviceReady, false);

function onDeviceReady() {

    // Mock device.platform property if not available
    if (!window.device) {
        window.device = { platform: 'Browser' };
    }

    handleExternalURLs();
}

function handleExternalURLs() {
    // Handle click events for all external URLs
    if (device.platform.toUpperCase() === 'ANDROID') {
        $(document).on('click', 'a[href^="http"]', function (e) {
            var url = $(this).attr('href');
            navigator.app.loadUrl(url, { openExternal: true });
            e.preventDefault();
        });
    }
    else if (device.platform.toUpperCase() === 'IOS') {
        $(document).on('click', 'a[href^="http"]', function (e) {
            var url = $(this).attr('href');
            window.open(url, '_system');
            e.preventDefault();
        });
    }
    else {
        // Leave standard behaviour
    }
}

So as you can see I am checking the device platform and depending on that I am using a different method. In case of a standard browser, I leave standard behaviour. From now on the solution will work fine on Android, iOS and in a browser, while HTML page won't be changed, so that it can have URLs represented as standard anchor

The solution requires InAppBrowser and Device plugins

I found this post which suggested to have two separate IP addresses so that both could listen on port 80.

There was a caveat that you had to make a change in IIS because of socket pooling. Here are the instructions based on the link above:

1. Extract the httpcfg.exe utility from the support tools area on the Win2003 CD.
2. Stop all IIS services: net stop http /y
3. Have IIS listen only on the IP address I'd designated for IIS: httpcfg set iplisten -i 192.168.1.253
4. Make sure: httpcfg query iplisten (The IPs listed are the only IP addresses that IIS will be listening on and no other.)
5. Restart IIS Services: net start w3svc
6. Start the Apache service

For testing only two values, I'd personally do this:

if x ~= 0 and x ~= 1 then
    print( "X must be equal to 1 or 0" )
    return
end

If you need to test against more than two values, I'd stuff your choices in a table acting like a set, like so:

choices = {[0]=true, [1]=true, [3]=true, [5]=true, [7]=true, [11]=true}

if not choices[x] then
    print("x must be in the first six prime numbers")
    return
end

This does not work in Python 3.

You can use functools cmp_to_key to have old-style comparison functions work though.

from functools import cmp_to_key

def cmp_items(a, b):
    if a.foo > b.foo:
        return 1
    elif a.foo == b.foo:
        return 0
    else:
        return -1

cmp_items_py3 = cmp_to_key(cmp_items)

alist.sort(cmp_items_py3)

boost::lexical_cast<std::string>(yourint) from boost/lexical_cast.hpp

Work's for everything with std::ostream support, but is not as fast as, for example, itoa

It even appears to be faster than stringstream or scanf:

• http://www.boost.org/doc/libs/1_53_0/doc/html/boost_lexical_cast/performance.html

For setting up virtual hosts on Apache http-servers that are not yet connected via DNS, I like to use:

curl -s --connect-to ::host-name: http://project1.loc/post.json

Where host-name ist the IP address or the DNS name of the machine on which the web-server is running. This also works well for https-Sites.

HTML rows and cols are not responsive!

So I define the size in CSS. As a tip: if you define a small size for mobiles think about using textarea:focus {};

Add some extra space here, which will only unfold the moment a user wants to actually write something

@font-face {
    font-family: Kaffeesatz;
    src: url(YanoneKaffeesatz-Thin.otf);
    font-weight: 200;
}
@font-face {
    font-family: Kaffeesatz;
    src: url(YanoneKaffeesatz-Light.otf);
    font-weight: 300;
}
@font-face {
    font-family: Kaffeesatz;
    src: url(YanoneKaffeesatz-Regular.otf);
    font-weight: normal;
}
@font-face {
    font-family: Kaffeesatz;
    src: url(YanoneKaffeesatz-Bold.otf);
    font-weight: bold;
}
h3, h4, h5, h6 {
    font-size:2em;
    margin:0;
    padding:0;
    font-family:Kaffeesatz;
    font-weight:normal;
}
h6 { font-weight:200; }
h5 { font-weight:300; }
h4 { font-weight:normal; }
h3 { font-weight:bold; }

Easiest way:

cin.seekg(0,ios::end);
cin.clear();

It just positions the cin pointer at the end of the stdin stream and cin.clear() clears all error flags such as the EOF flag.

Try using list.AddRange(VTSWeb.GetDailyWorktimeViolations(VehicleID2));

Using Node Version Manager (NVM):

Install it:

wget -qO- https://raw.githubusercontent.com/creationix/nvm/v0.33.11/install.sh | bash

Test your installation:

close your current terminal, open a new terminal, and run:

command -v nvm

Use it to install as many versions as u like:

nvm install 8              # Install nodejs 8
nvm install --lts          # Install latest LTS (Long Term Support) version

List installed versions:

nvm ls

Use a specific version:

nvm use 8                  # Use this version on this shell

Set defaults:

nvm alias default 8        # Default to nodejs 8 on this shell
nvm alias default node     # always use latest available as default nodejs for all shells

Another potential cause for this (Intellij was involved in my case, not sure that mattered though): trying to merge in changes from a main branch into a branch off of a feature branch.

In other words, merging "main" into "current" in the following arrangement:

main
  |
  --feature
      |
      --current

I resolved all conflicts and GiT reported unmerged files and I was stuck until I merged from main into feature, then feature into current.

If what is happening is that you have another server running on localhost and you want to give this new server a different local hostname like http://teamviewer/

I think that what you are actually looking for is Virtual Hosts functionality. I use Apache so I do not know how other web daemons support this. Maybe it is called Alias. Here is the Apache documentation:

Apache Virtual Hosts examples

Perhaps you want Hash#merge ?

1.9.3p194 :015 > h={}
 => {} 
1.9.3p194 :016 > h.merge(:key => 'bar')
 => {:key=>"bar"} 
1.9.3p194 :017 > 

If you want to change the array in place use merge!

1.9.3p194 :016 > h.merge!(:key => 'bar')
 => {:key=>"bar"} 

Yes. Only override it in that one Activity with

@Override
public void onBackPressed()
{
     // code here to show dialog
     super.onBackPressed();  // optional depending on your needs
}

don't put this code in any other Activity

you can use guava's Multimaps

@Canonical
class Persion {
     String name
     Integer age
}
List<Persion> list = [
   new Persion("qianzi", 100),
   new Persion("qianzi", 99),
   new Persion("zhijia", 99)
]
println Multimaps.index(list, { Persion p -> return p.name })

it print:

[qianzi:[com.ctcf.message.Persion(qianzi, 100),com.ctcf.message.Persion(qianzi, 88)],zhijia:[com.ctcf.message.Persion(zhijia, 99)]]

@jeminar has the best solution above.

I cleaned it up a bit though.

I recommend adding this to a FunctionsArray module

• isInitialised=false is not needed because Booleans are false when created
• On Error GoTo 0 wrap and indent code inside error blocks similar to with blocks for visibility. these methods should be avoided as much as possible but ... VBA ...

Function isInitialised(ByRef a() As Variant) As Boolean
    On Error Resume Next
    isInitialised = IsNumeric(UBound(a))
    On Error GoTo 0
End Function

For the first question I think answer would be:

<your DataFrame>.rename(columns={'count':'Total_Numbers'})

or

<your DataFrame>.columns = ['ID', 'Region', 'Total_Numbers']

As for second one I'd say the answer would be no. It's possible to use it like 'df.ID' because of python datamodel:

Attribute references are translated to lookups in this dictionary, e.g., m.x is equivalent to m.dict["x"]

There's no built-in command for that because it's illegal. You can't modify the size of an array once declared.

What you're looking for is either std::vector to simulate a dynamic array, or better yet a std::string.

std::string first ("The dog jumps ");
std::string second ("over the log");
std::cout << first + second << std::endl;

When you are in android studio 3 or above you need to add following lines AndroidManifest.xml file

<activity
            android:name=".MainActivity"
            android:configChanges="orientation"
            android:screenOrientation= "sensorLandscape"
            tools:ignore="LockedOrientationActivity">

One thing this is sensor Landscape, means it will work on both landscape sides

But if you only want to work the regular landscape side then, replace sensorLandscape to landscape

Most debugger consoles support displaying objects directly. Just use

console.log(obj);

Depending on your debugger this most likely will display the object in the console as a collapsed tree. You can open the tree and inspect the object.

Given the ease of use of Access, I don't see a compelling reason to use Excel at all other than to export data for number crunching. Access is designed to easily build data forms and, in my opinion, will be orders of magnitude easier and less time-consuming than using Excel. A few hours to learn the Access object model will pay for itself many times over in terms of time and effort.

No, it's not possible. Not without the export keyword, which for all intents and purposes doesn't really exist.

The best you can do is put your function implementations in a ".tcc" or ".tpp" file, and #include the .tcc file at the end of your .hpp file. However this is merely cosmetic; it's still the same as implementing everything in header files. This is simply the price you pay for using templates.

Very easy:

To set a menu item's image dynamically, only do the following:

MyMenuItem.ImageSource = 
    new BitmapImage(new Uri("Resource/icon.ico",UriKind.Relative));

...whereas "icon.ico" can be located everywhere (currently it's located in the 'Resources' directory) and must be linked as Resource...

You can also use regex for this:

std::vector<std::string> split(const std::string str, const std::string regex_str)
{
    std::regex regexz(regex_str);
    std::vector<std::string> list(std::sregex_token_iterator(str.begin(), str.end(), regexz, -1),
                                  std::sregex_token_iterator());
    return list;
}

which is equivalent to :

std::vector<std::string> split(const std::string str, const std::string regex_str)
{
    std::sregex_token_iterator token_iter(str.begin(), str.end(), regexz, -1);
    std::sregex_token_iterator end;
    std::vector<std::string> list;
    while (token_iter != end)
    {
        list.emplace_back(*token_iter++);
    }
    return list;
}

and use it like this :

#include <iostream>
#include <string>
#include <regex>

std::vector<std::string> split(const std::string str, const std::string regex_str)
{   // a yet more concise form!
    return { std::sregex_token_iterator(str.begin(), str.end(), std::regex(regex_str), -1), std::sregex_token_iterator() };
}

int main()
{
    std::string input_str = "lets split this";
    std::string regex_str = " "; 
    auto tokens = split(input_str, regex_str);
    for (auto& item: tokens)
    {
        std::cout<<item <<std::endl;
    }
}

play with it online! http://cpp.sh/9sumb

you can simply use substrings, characters, etc like normal, or use actual regular expressions to do the splitting.
its also concise and C++11!

How is main called?

When you are using the console application template the code will be compiled requiring a method called Main in the startup object as Main is market as entry point to the application.

By default no startup object is specified in the project propery settings and the Program class will be used by default. You can change this in the project property under the "Build" tab if you wish.

Keep in mind that which ever object you assign to be the startup object must have a method named Main in it.

How are args passed to main method

The accepted format is MyConsoleApp.exe value01 value02 etc...

The application assigns each value after each space into a separate element of the parameter array.

Thus, MyConsoleApp.exe value01 value02 will mean your args paramter has 2 elements:

[0] = "value01"

[1] = "value02"

How you parse the input values and use them is up to you.

Hope this helped.

Here's stored procedure, which will generate the table based on data from one table and column and data from other table and column.

The function 'sum(if(col = value, 1,0)) as value ' is used. You can choose from different functions like MAX(if()) etc.

    SET @sql = CONCAT('SELECT p.', 
        columnB, 
        ', ', 
        @sql, 
        ' FROM ', tableB, ' p GROUP BY p.',
        columnB,'');

    -- select @sql;

    /* */
    PREPARE stmt FROM @sql;
    EXECUTE stmt;
    /* */
    DEALLOCATE PREPARE stmt;
end//

delimiter ;

Use the %d format specifier with a comma: %,d

This is by far the easiest way.

Apparently you don't need to specify height at all! Which is great if it changes for some reason (you resize components or change font sizes).

I just followed this tutorial and everything worked: http://natashatherobot.com/ios-autolayout-scrollview/

(Side note: There is no need to implement viewDidLayoutSubviews unless you want to center the view, so the list of steps is even shorter).

Hope that helps!

top object makes more sense inside frames. Inside a frame, window refers to current frame's window while top refers to the outermost window that contains the frame(s). So:

window.location.href = 'somepage.html'; means loading somepage.html inside the frame.

top.location.href = 'somepage.html'; means loading somepage.html in the main browser window.

Two other interesting objects are self and parent.

Oh. I think you're writing the workbook out 944,000 times. Your wb.write(bos) call is in the inner loop. I'm not sure this is quite consistent with the semantics of the Workbook class? From what I can tell in the Javadocs of that class, that method writes out the entire workbook to the output stream specified. And it's gonna write out every row you've added so far once for every row as the thing grows.

This explains why you're seeing exactly 1 row, too. The first workbook (with one row) to be written out to the file is all that is being displayed - and then 7GB of junk thereafter.

Thanks a bundle, guys. You are great.

I used Chuff's answer and modified it a little to do what I wanted.

I have 2 worksheets in the same workbook.

On 1st worksheet I have a list of SMS in 3 columns: phone number, date & time, message

Then I inserted a new blank column next to the phone number

On worksheet 2 I have two columns: phone number, name of person

Used the formula to check the cell on the left, and match against the range in worksheet 2, pick the name corresponding to the number and input it into the blank cell in worksheet 1.

Then just copy the formula down the whole column until last sms It worked beautifully.

=VLOOKUP(A3,Sheet2!$A$1:$B$31,2,0)

I had similar problem. I needed to write down csv file on driver while I was connect to cluster in client mode.

I wanted to reuse the same CSV parsing code as Apache Spark to avoid potential errors.

I checked spark-csv code and found code responsible for converting dataframe into raw csv RDD[String] in com.databricks.spark.csv.CsvSchemaRDD.

Sadly it is hardcoded with sc.textFile and the end of relevant method.

I copy-pasted that code and removed last lines with sc.textFile and returned RDD directly instead.

My code:

/*
  This is copypasta from com.databricks.spark.csv.CsvSchemaRDD
  Spark's code has perfect method converting Dataframe -> raw csv RDD[String]
  But in last lines of that method it's hardcoded against writing as text file -
  for our case we need RDD.

I found another, rather quick and dirty, solution. If you use the low level approach to implement the WebSocket and you Implement the onOpen method yourself you receive an object implementing the WebSocket.Connection interface. This object has a setMaxIdleTime method which you can adjust.

You might have to move the mouse to any particular location after context click() like this -

Actions action = new Actions(driver);
actions.contextClick(link).moveByOffset(x,y).click().build().perform();

To understand how moveByOffset(x,y) works look here;

I hope this works. You will have to calculate the offset values for x and y;

best way would be to find the size of each option button after right clicking and then if you click on the 2nd option .

x = width of option button/2

y = 2*(size of each option button)

You can nest one array within another using the shorthand syntax:

   var twoDee = [[]];

Assuming your page is available under "http://example.com"

from selenium import webdriver
from selenium.webdriver.common.keys import Keys

driver = webdriver.Firefox()
driver.get("http://example.com")

Select element by id:

inputElement = driver.find_element_by_id("a1")
inputElement.send_keys('1')

Now you can simulate hitting ENTER:

inputElement.send_keys(Keys.ENTER)

or if it is a form you can submit:

inputElement.submit() 

pom is basically a container of submodules, each submodule is represented by a subdirectory in the same directory as pom.xml with pom packaging.

Somewhere, nested within the project structure you will find artifacts (modules) with war packaging. Maven generally builds everything into /target subdirectories of each module. So after mvn install look into target subdirectory in a module with war packaging.

Of course:

$ find . -iname "*.war"

works equally well ;-).

I'm rather shocked that this has not been answered since the solution is very simple.

As mentioned in previous posts, you would not want to convert it using C#, but just once. This is easy to do with PuTTYGen.

1. Download your .pem from AWS
2. Open PuTTYgen
3. Click "Load" on the right side about 3/4 down
4. Set the file type to *.*
5. Browse to, and Open your .pem file
6. PuTTY will auto-detect everything it needs, and you just need to click "Save private key" and you can save your ppk key for use with PuTTY

Enjoy!

Delete .gradle folder(root directory) and build folder(project directory) and then invalidate caches/restart android studio, run your project again hopefully it will work. It might take some time for the background tasks. In some countries, you may need to turn on the VPN to download.

I think that mobile devices dont work with fixed positions. You should try with some js plugin like skrollr.js (for example). With this kind of plugin you can select the position of your div (or whatever) in function of scrollbar position.

Just append a div with that class to body, then remove it when you're done:

// Show the backdrop
$('<div class="modal-backdrop"></div>').appendTo(document.body);

// Remove it (later)
$(".modal-backdrop").remove();

Live Example:

The most trivial way to upload a file over SFTP with JSch is:

JSch jsch = new JSch();
Session session = jsch.getSession(user, host);
session.setPassword(password);
session.connect();

ChannelSftp sftpChannel = (ChannelSftp) session.openChannel("sftp");
sftpChannel.connect();

sftpChannel.put("C:/source/local/path/file.zip", "/target/remote/path/file.zip");

Similarly for a download:

sftpChannel.get("/source/remote/path/file.zip", "C:/target/local/path/file.zip");

You may need to deal with UnknownHostKey exception.

Here's an approach that could resolve your problem, and if not would help with troubleshooting.

1. Create a second Apache virtual server identical to the current one

2. Send all "normal" user traffic to the original virtual server

3. Send special or long-running traffic to the new virtual server

Special or long-running traffic could be report-generation, maintenance ops or anything else you don't expect to complete in <<1 second. This can happen serving APIs, not just web pages.

If your resource utilization is low but you still exceed MaxClients, the most likely answer is you have new connections arriving faster than they can be serviced. Putting any slow operations on a second virtual server will help prove if this is the case. Use the Apache access logs to quantify the effect.

The reason for the exception is that and implicitly calls bool. First on the left operand and (if the left operand is True) then on the right operand. So x and y is equivalent to bool(x) and bool(y).

However the bool on a numpy.ndarray (if it contains more than one element) will throw the exception you have seen:

>>> import numpy as np
>>> arr = np.array([1, 2, 3])
>>> bool(arr)
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

The bool() call is implicit in and, but also in if, while, or, so any of the following examples will also fail:

>>> arr and arr
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

>>> if arr: pass
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

>>> while arr: pass
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

>>> arr or arr
ValueError: The truth value of an array with more than one element is ambiguous. Use a.any() or a.all()

There are more functions and statements in Python that hide bool calls, for example 2 < x < 10 is just another way of writing 2 < x and x < 10. And the and will call bool: bool(2 < x) and bool(x < 10).

The element-wise equivalent for and would be the np.logical_and function, similarly you could use np.logical_or as equivalent for or.

For boolean arrays - and comparisons like <, <=, ==, !=, >= and > on NumPy arrays return boolean NumPy arrays - you can also use the element-wise bitwise functions (and operators): np.bitwise_and (& operator)

>>> np.logical_and(arr > 1, arr < 3)
array([False,  True, False], dtype=bool)

>>> np.bitwise_and(arr > 1, arr < 3)
array([False,  True, False], dtype=bool)

>>> (arr > 1) & (arr < 3)
array([False,  True, False], dtype=bool)

and bitwise_or (| operator):

>>> np.logical_or(arr <= 1, arr >= 3)
array([ True, False,  True], dtype=bool)

>>> np.bitwise_or(arr <= 1, arr >= 3)
array([ True, False,  True], dtype=bool)

>>> (arr <= 1) | (arr >= 3)
array([ True, False,  True], dtype=bool)

A complete list of logical and binary functions can be found in the NumPy documentation:

• "Logic functions"
• "Binary operations"

Note that the if $myVar; then ... ;fi construct has a security problem you might want to avoid with

case $myvar in
  (true)    echo "is true";;
  (false)   echo "is false";;
  (rm -rf*) echo "I just dodged a bullet";;
esac

You might also want to rethink why if [ "$myvar" = "true" ] appears awkward to you. It's a shell string comparison that beats possibly forking a process just to obtain an exit status. A fork is a heavy and expensive operation, while a string comparison is dead cheap. Think a few CPU cycles versus several thousand. My case solution is also handled without forks.

You can use __CLASS__ within a class to get the name.

This is what I've been using. It's simple and it works well.

#pragma mark - Scrolling

-(void)scrollElement:(UIView *)view toPoint:(float)y
{
    CGRect theFrame = view.frame;
    float orig_y = theFrame.origin.y;
    float diff = y - orig_y;

    if (diff < 0) 
        [self scrollToY:diff];

    else 
        [self scrollToY:0];
}

-(void)scrollToY:(float)y
{
    [UIView animateWithDuration:0.3f animations:^{
        [UIView setAnimationCurve:UIViewAnimationCurveEaseInOut];
        self.view.transform = CGAffineTransformMakeTranslation(0, y);
    }];
}

Use the UITextField delegate call textFieldDidBeginEditing: to shift your view upwards, and also add a notification observer to return the view to normal when the keyboard hides:

-(void)textFieldDidBeginEditing:(UITextField *)textField
{
    [[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(keyboardWillHide:) name:UIKeyboardWillHideNotification object:nil];

    if (self.view.frame.origin.y == 0)
        [self scrollToY:-90.0];  // y can be changed to your liking

}

-(void)keyboardWillHide:(NSNotification*)note
{
    [self scrollToY:0];
    [[NSNotificationCenter defaultCenter] removeObserver:self name:UIKeyboardWillHideNotification object:nil];
}

Gradle is an advanced build toolkit for android that manages dependencies and allows you to define custom build logic. features are like

• Customize, configure, and extend the build process.

• Create multiple APKs for your app with different features using the same project.

• Reuse code and resources.

I typically do this sort of thing by defining a custom [Serializable] settings class and simply serializing it to disk. In your case you could just as easily store it as a string blob in your SQLite database.

You can go to File -> Preferences -> Keyboard Shortcut. Once you are there, you can search for navigate. Then, you will see all shortcuts set for your VS Code environment related to navigation. In my case, it was only Alt + '-' to get my cursor back.
