Move semantics allows for a straightforward way to release memory, by simply applying the assignment (=) operator from an empty rvalue:

std::vector<uint32_t> vec(100, 0);
std::cout << vec.capacity(); // 100

vec = vector<uint32_t>();    // Same as "vector<uint32_t>().swap(vec)";    
std::cout << vec.capacity(); // 0

It is as much efficient as the "swap()"-based method described in other answers (indeed, both are conceptually doing the same thing). When it comes to readability, however, the assignment version makes a better job at expressing the programmer's intention while being more concise.

EDIT: Use an OrderedDictionary.

It's better to use FirstOrDefault() to retrieve the first value.

Ex:

var firstElement = like.FirstOrDefault();
string firstElementKey = firstElement.Key;
Dictinary<string,string> firstElementValue = firstElement.Value;

1. File\Settings... (Ctrl+Alt+S)
2. Project Settings > Editor > Code Style > Java > Imports tab
3. Set Class count to use import with '*' to 999
4. Set Names count to use static import with '*' to 999

After this, your configuration should look like:

There's also concat, but it doesn't get used much

select concat('a','b') from dual;

The function scipy.signal.find_peaks, as its name suggests, is useful for this. But it's important to understand well its parameters width, threshold, distance and above all prominence to get a good peak extraction.

According to my tests and the documentation, the concept of prominence is "the useful concept" to keep the good peaks, and discard the noisy peaks.

What is (topographic) prominence? It is "the minimum height necessary to descend to get from the summit to any higher terrain", as it can be seen here:

The idea is:

The higher the prominence, the more "important" the peak is.

Test:

I used a (noisy) frequency-varying sinusoid on purpose because it shows many difficulties. We can see that the width parameter is not very useful here because if you set a minimum width too high, then it won't be able to track very close peaks in the high frequency part. If you set width too low, you would have many unwanted peaks in the left part of the signal. Same problem with distance. threshold only compares with the direct neighbours, which is not useful here. prominence is the one that gives the best solution. Note that you can combine many of these parameters!

Code:

import numpy as np
import matplotlib.pyplot as plt 
from scipy.signal import find_peaks

x = np.sin(2*np.pi*(2**np.linspace(2,10,1000))*np.arange(1000)/48000) + np.random.normal(0, 1, 1000) * 0.15
peaks, _ = find_peaks(x, distance=20)
peaks2, _ = find_peaks(x, prominence=1)      # BEST!
peaks3, _ = find_peaks(x, width=20)
peaks4, _ = find_peaks(x, threshold=0.4)     # Required vertical distance to its direct neighbouring samples, pretty useless
plt.subplot(2, 2, 1)
plt.plot(peaks, x[peaks], "xr"); plt.plot(x); plt.legend(['distance'])
plt.subplot(2, 2, 2)
plt.plot(peaks2, x[peaks2], "ob"); plt.plot(x); plt.legend(['prominence'])
plt.subplot(2, 2, 3)
plt.plot(peaks3, x[peaks3], "vg"); plt.plot(x); plt.legend(['width'])
plt.subplot(2, 2, 4)
plt.plot(peaks4, x[peaks4], "xk"); plt.plot(x); plt.legend(['threshold'])
plt.show()

Using the isDebugEnabled() is reserved for when you're building up log messages by concatenating Strings:

Var myVar = new MyVar();
log.debug("My var is " + myVar + ", value:" + myVar.someCall());

However, in your example there is no speed gain as you're just logging a String and not performing operations such as concatenation. Therefore you're just adding bloat to your code and making it harder to read.

I personally use the Java 1.5 format calls in the String class like this:

Var myVar = new MyVar();
log.debug(String.format("My var is '%s', value: '%s'", myVar, myVar.someCall()));

I doubt there's much optimisation but it's easier to read.

Do note though that most logging APIs offer formatting like this out of the box: slf4j for example provides the following:

logger.debug("My var is {}", myVar);

which is even easier to read.

You can learn more about AUROC in this blog post by Miron Kursa:

https://mbq.me/blog/augh-roc/

He provides a fast function for AUROC:

# By Miron Kursa https://mbq.me
auroc <- function(score, bool) {
  n1 <- sum(!bool)
  n2 <- sum(bool)
  U  <- sum(rank(score)[!bool]) - n1 * (n1 + 1) / 2
  return(1 - U / n1 / n2)
}

Let's test it:

set.seed(42)
score <- rnorm(1e3)
bool  <- sample(c(TRUE, FALSE), 1e3, replace = TRUE)

pROC::auc(bool, score)
mltools::auc_roc(score, bool)
ROCR::performance(ROCR::prediction(score, bool), "auc")@y.values[[1]]
auroc(score, bool)

0.51371668847094
0.51371668847094
0.51371668847094
0.51371668847094

auroc() is 100 times faster than pROC::auc() and computeAUC().

auroc() is 10 times faster than mltools::auc_roc() and ROCR::performance().

This is what I used in a project, parses a single line of data.

    private string[] csvParser(string csv, char separator = ',')
    {
        List <string> = new <string>();
        string[] temp = csv.Split(separator);
        int counter = 0;
        string data = string.Empty;
        while (counter < temp.Length)
        {
            data = temp[counter].Trim();
            if (data.Trim().StartsWith("\""))
            {
                bool isLast = false;
                while (!isLast && counter < temp.Length)
                {
                    data += separator.ToString() + temp[counter + 1];
                    counter++;
                    isLast = (temp[counter].Trim().EndsWith("\""));
                }
            }
            parsed.Add(data);
            counter++;
        }

        return parsed.ToArray();

Oddly enough, the issue for me was I was trying to open 2012 SQL Server Integration Services on SSMS 2008 R2. When I opened the same in SSMS 2012, it connected right away.

If you want to do it from the command line and not built into the script itself, use:

.\myscript.ps1 | Out-File c:\output.csv

set this jquery min js

script src="http://code.jquery.com/jquery-1.10.1.min.js"

in wp-admin/admin-header.php

For Windows:

1. Install the necessary plugins for the repository (ex: GitHub install GitHub and GitHub Authentication plugins) in Jenkins.
2. You can generate a key with Putty key generator, or by running the following command in git bash: $ ssh-keygen -t rsa -b 4096 -C [email protected]
3. Private key must be OpenSSH. You can convert your private key to OpenSSH in putty key generator
4. SSH keys come in pairs, public and private. Public keys are inserted in the repository to be cloned. Private keys are saved as credentials in Jenkins
5. You need to copy the SSH URL not the HTTPS to work with ssh keys.

Just for completeness, let's not forget the Simplest Thing That Could Possibly Work:

for i in list:
  if i.n == 5:
     # do something with it
     print "YAY! Found one!"

My current solution solves most of the issues you mentioned yet its completely abstracted from platform specific things and can be reused. Also i used no code-behind only binding with DelegateCommands that implement ICommand. Dialog is basically a View - a separate control that has its own ViewModel and it is shown from the ViewModel of the main screen but triggered from the UI via DelagateCommand binding.

See full Silverlight 4 solution here Modal dialogs with MVVM and Silverlight 4

Use:

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

The option you should use is iDisplayLength:

$('#adminProducts').dataTable({
  'iDisplayLength': 100
});

$('#table').DataTable({
   "lengthMenu": [ [5, 10, 25, 50, -1], [5, 10, 25, 50, "All"] ]
});

It will Load by default all entries.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
    iDisplayLength: -1
});

Or if using 1.10+

$('#example').dataTable({
    paging: false
});

If you want to load by default 25 not all do this.

$('#example').dataTable({
    aLengthMenu: [
        [25, 50, 100, 200, -1],
        [25, 50, 100, 200, "All"]
    ],
});

You can use a DOMParser, like so:

var xmlString = "<div id='foo'><a href='#'>Link</a><span></span></div>";_x000D_
var doc = new DOMParser().parseFromString(xmlString, "text/xml");_x000D_
console.log(doc.firstChild.innerHTML); // => <a href="#">Link..._x000D_
console.log(doc.firstChild.firstChild.innerHTML); // => Link

Also this happens when I was installing mysqlclient,

$ pip install mysqlclient

As user3429036 said,

$ brew install mysql

The following adds -1 years to the current date:

SELECT ... From ... WHERE date > DATEADD(year,-1,GETDATE())

You can also do this:

Add a maxlength attribute to your input.

<input type="text" id="phone" name="phone" maxlength="10">

See this working example on JSFiddle.

Use the format() function with a '02x' format.

>>> format(255, '02x')
'ff'
>>> format(2, '02x')
'02'

The 02 part tells format() to use at least 2 digits and to use zeros to pad it to length, x means lower-case hexadecimal.

The Format Specification Mini Language also gives you X for uppercase hex output, and you can prefix the field width with # to include a 0x or 0X prefix (depending on wether you used x or X as the formatter). Just take into account that you need to adjust the field width to allow for those extra 2 characters:

>>> format(255, '02X')
'FF'
>>> format(255, '#04x')
'0xff'
>>> format(255, '#04X')
'0XFF'

^\d{5}(?:[-\s]\d{4})?$

• ^ = Start of the string.
• \d{5} = Match 5 digits (for condition 1, 2, 3)
• (?:…) = Grouping
• [-\s] = Match a space (for condition 3) or a hyphen (for condition 2)
• \d{4} = Match 4 digits (for condition 2, 3)
• …? = The pattern before it is optional (for condition 1)
• $ = End of the string.

This would get all files in path/to/files with an .swf extension into an array and then sort that array by the file's mtime

$files = glob('path/to/files/*.swf');
usort($files, function($a, $b) {
    return filemtime($b) - filemtime($a);
});

The above uses an Lambda function and requires PHP 5.3. Prior to 5.3, you would do

usort($files, create_function('$a,$b', 'return filemtime($b)-filemtime($a);'));

If you don't want to use an anonymous function, you can just as well define the callback as a regular function and pass the function name to usort instead.

With the resulting array, you would then iterate over the files like this:

foreach($files as $file){
    printf('<tr><td><input type="checkbox" name="box[]"></td>
            <td><a href="%1$s" target="_blank">%1$s</a></td>
            <td>%2$s</td></tr>', 
            $file, // or basename($file) for just the filename w\out path
            date('F d Y, H:i:s', filemtime($file)));
}

Note that because you already called filemtime when sorting the files, there is no additional cost when calling it again in the foreach loop due to the stat cache.

I agree with the other two answers: install the Apple Developer Tools.

But it is also worth noting that OS X ships with ant and rake.

Detecting and embedding Flash within a web document is a surprisingly difficult task.

I was very disappointed with the quality and non-standards compliant markup generated from both SWFObject and Adobe's solutions. Additionally, my testing found Adobe's auto updater to be inconsistent and unreliable.

The JavaScript Flash Detection Library (Flash Detect) and JavaScript Flash HTML Generator Library (Flash TML) are a legible, maintainable and standards compliant markup solution.

You can find the list of duplicate names using the following aggregate pipeline:

• Group all the records having similar name.
• Match those groups having records greater than 1.
• Then group again to project all the duplicate names as an array.

The Code:

db.collection.aggregate([
{$group:{"_id":"$name","name":{$first:"$name"},"count":{$sum:1}}},
{$match:{"count":{$gt:1}}},
{$project:{"name":1,"_id":0}},
{$group:{"_id":null,"duplicateNames":{$push:"$name"}}},
{$project:{"_id":0,"duplicateNames":1}}
])

o/p:

{ "duplicateNames" : [ "ksqn291", "ksqn29123213Test" ] }

Actually, I solved the problem. I run it by eclipse jetty plugin.

1. I didn't have the JDK lib in my eclipse, that's why the message keep showing that I need the full JDK installed, that's the main reason.

2. I installed two versions of jetty plugin, wich is jetty7 and jetty8. I think they conflict with each other or something, so I removed the jetty7, and it works!

Another vote for if/else. I'm not a huge fan of case or switch statements because there are some people that don't use them. The code is less readable if you use case or switch. Maybe not less readable to you, but to those that have never needed to use the command.

The same goes for object factories.

If/else blocks are a simple construct that everyone gets. There's a few things you can do to make sure that you don't cause problems.

Firstly - Don't try and indent if statements more than a couple of times. If you're finding yourself indenting, then you're doing it wrong.

 if a = 1 then 
     do something else 
     if a = 2 then 
         do something else
     else 
         if a = 3 then 
             do the last thing
         endif
     endif 
  endif

Is really bad - do this instead.

if a = 1 then 
   do something
endif 
if a = 2 then 
   do something else
endif 
if a = 3 then 
   do something more
endif 

Optimisation be damned. It doesn't make that much of a difference to the speed of your code.

Secondly, I'm not averse to breaking out of an If Block as long as there are enough breaks statements scattered through the particular code block to make it obvious

procedure processA(a:int)
    if a = 1 then 
       do something
       procedure_return
    endif 
    if a = 2 then 
       do something else
       procedure_return
    endif 
    if a = 3 then 
       do something more
       procedure_return
    endif 
end_procedure

EDIT: On Switch and why I think it's hard to grok:

Here's an example of a switch statement...

private void doLog(LogLevel logLevel, String msg) {
   String prefix;
   switch (logLevel) {
     case INFO:
       prefix = "INFO";
       break;
     case WARN:
       prefix = "WARN";
       break;
     case ERROR:
       prefix = "ERROR";
       break;
     default:
       throw new RuntimeException("Oops, forgot to add stuff on new enum constant");
   }
   System.out.println(String.format("%s: %s", prefix, msg));
 }

For me the issue here is that the normal control structures which apply in C like languages have been completely broken. There's a general rule that if you want to place more than one line of code inside a control structure, you use braces or a begin/end statement.

e.g.

for i from 1 to 1000 {statement1; statement2}
if something=false then {statement1; statement2}
while isOKtoLoop {statement1; statement2}

For me (and you can correct me if I'm wrong), the Case statement throws this rule out of the window. A conditionally executed block of code is not placed inside a begin/end structure. Because of this, I believe that Case is conceptually different enough to not be used.

Hope that answers your questions.

Given

d = [[180.0], [173.8], [164.2], [156.5], [147.2], [138.2]]

and your specific question: How can I remove the brackets?

Using list comprehension :

new_d = [i[0] for i in d]

will give you this

[180.0, 173.8, 164.2, 156.5, 147.2, 138.2]

then you can access individual items with the appropriate index, e.g., new_d[0] will give you 180.0 etc which you can then use for math.

If you are going to have a collection of data, you will have some sort of bracket or parenthesis.

Note, this solution is aimed specifically at your question/problem, it doesn't provide a generalized solution. I.e., it will work for your case.

Look at the following code

$("#clickMe").click(function (e) {
    var $this = $(this);
    if ($this.hasClass('clicked')){
        alert("Double click");
        //here is your code for double click
        return;
    }else{
         $this.addClass('clicked');
        //your code for single click
         setTimeout(function() { 
                 $this.removeClass('clicked'); },500);
    }//end of else
});

You can specify GLOBIGNORE and use the pattern *

GLOBIGNORE='ignore1:ignore2' scp -r source/* remoteurl:remoteDir

You may wish to have general rules which you combine or override by using export GLOBIGNORE, but for ad-hoc usage simply the above will do. The : character is used as delimiter for multiple values.

You are confusing regular expression with shell globbing. If you want to use regular expression to match file names you could do:

$ ls | egrep '.+\..+'

I really enjoy a new literal string interpolation in Python 3.6+:

line_new = f'{word[0]:>12}  {word[1]:>12}  {word[2]:>12}'

Reference: PEP 498 -- Literal String Interpolation

I prefer .hpp for C++ to make it clear to both editors and to other programmers that it is a C++ header rather than a C header file.

You can also install simplejson.

If you have pip (see https://pypi.python.org/pypi/pip) as your Python package manager you can install simplejson with:

 pip install simplejson

This is similar to the comment of installing with easy_install, but I prefer pip to easy_install as you can easily uninstall in pip with "pip uninstall package".

For my case, the problem was due to losing of the internet connection in my WiFi.

Thanks to both of you. This worked perfectly for me.

$("input[type='text'][id*=" + strID + "]:visible").each(function() {
    this.value=strVal;
});

Try this

int sum = 0;
foreach (DataRow dr in dt.Rows)
{
     dynamic value = dr[index].ToString();
     if (!string.IsNullOrEmpty(value))
     { 
         sum += Convert.ToInt32(value);
     }
}

urlparse is fine to use if you want to (say, to get rid of any query string parameters).

import urllib.parse

urls = [
    'http://www.test.com/TEST1',
    'http://www.test.com/page/TEST2',
    'http://www.test.com/page/page/12345',
    'http://www.test.com/page/page/12345?abc=123'
]

for i in urls:
    url_parts = urllib.parse.urlparse(i)
    path_parts = url_parts[2].rpartition('/')
    print('URL: {}\nreturns: {}\n'.format(i, path_parts[2]))

Output:

URL: http://www.test.com/TEST1
returns: TEST1

URL: http://www.test.com/page/TEST2
returns: TEST2

URL: http://www.test.com/page/page/12345
returns: 12345

URL: http://www.test.com/page/page/12345?abc=123
returns: 12345

Another alternative that only affects the current connection:

SET SESSION query_cache_type=0;

Yo,

This is how you do it if you want just one type of holder stick when it starts getting out of the screen (we are not caring about any sections). There is only one way without breaking the internal RecyclerView logic of recycling items and that is to inflate additional view on top of the recyclerView's header item and pass data into it. I'll let the code speak.

import android.graphics.Canvas
import android.graphics.Rect
import android.view.LayoutInflater
import android.view.View
import android.view.ViewGroup
import androidx.annotation.LayoutRes
import androidx.recyclerview.widget.RecyclerView

class StickyHeaderItemDecoration(@LayoutRes private val headerId: Int, private val HEADER_TYPE: Int) : RecyclerView.ItemDecoration() {

private lateinit var stickyHeaderView: View
private lateinit var headerView: View

private var sticked = false

// executes on each bind and sets the stickyHeaderView
override fun getItemOffsets(outRect: Rect, view: View, parent: RecyclerView, state: RecyclerView.State) {
    super.getItemOffsets(outRect, view, parent, state)

    val position = parent.getChildAdapterPosition(view)

    val adapter = parent.adapter ?: return
    val viewType = adapter.getItemViewType(position)

    if (viewType == HEADER_TYPE) {
        headerView = view
    }
}

override fun onDrawOver(c: Canvas, parent: RecyclerView, state: RecyclerView.State) {
    super.onDrawOver(c, parent, state)
    if (::headerView.isInitialized) {

        if (headerView.y <= 0 && !sticked) {
            stickyHeaderView = createHeaderView(parent)
            fixLayoutSize(parent, stickyHeaderView)
            sticked = true
        }

        if (headerView.y > 0 && sticked) {
            sticked = false
        }

        if (sticked) {
            drawStickedHeader(c)
        }
    }
}

private fun createHeaderView(parent: RecyclerView) = LayoutInflater.from(parent.context).inflate(headerId, parent, false)

private fun drawStickedHeader(c: Canvas) {
    c.save()
    c.translate(0f, Math.max(0f, stickyHeaderView.top.toFloat() - stickyHeaderView.height.toFloat()))
    headerView.draw(c)
    c.restore()
}

private fun fixLayoutSize(parent: ViewGroup, view: View) {

    // Specs for parent (RecyclerView)
    val widthSpec = View.MeasureSpec.makeMeasureSpec(parent.width, View.MeasureSpec.EXACTLY)
    val heightSpec = View.MeasureSpec.makeMeasureSpec(parent.height, View.MeasureSpec.UNSPECIFIED)

    // Specs for children (headers)
    val childWidthSpec = ViewGroup.getChildMeasureSpec(widthSpec, parent.paddingLeft + parent.paddingRight, view.getLayoutParams().width)
    val childHeightSpec = ViewGroup.getChildMeasureSpec(heightSpec, parent.paddingTop + parent.paddingBottom, view.getLayoutParams().height)

    view.measure(childWidthSpec, childHeightSpec)

    view.layout(0, 0, view.measuredWidth, view.measuredHeight)
}

}

And then you just do this in your adapter:

override fun onAttachedToRecyclerView(recyclerView: RecyclerView) {
    super.onAttachedToRecyclerView(recyclerView)
    recyclerView.addItemDecoration(StickyHeaderItemDecoration(R.layout.item_time_filter, YOUR_STICKY_VIEW_HOLDER_TYPE))
}

Where YOUR_STICKY_VIEW_HOLDER_TYPE is viewType of your what is supposed to be sticky holder.

<h:button>

The <h:button> generates a HTML <input type="button">. The generated element uses JavaScript to navigate to the page given by the attribute outcome, using a HTTP GET request.

E.g.

<h:button value="GET button" outcome="otherpage" />

will generate

<input type="button" onclick="window.location.href='/contextpath/otherpage.xhtml'; return false;" value="GET button" />

Even though this ends up in a (bookmarkable) URL change in the browser address bar, this is not SEO-friendly. Searchbots won't follow the URL in the onclick. You'd better use a <h:outputLink> or <h:link> if SEO is important on the given URL. You could if necessary throw in some CSS on the generated HTML <a> element to make it to look like a button.

Do note that while you can put an EL expression referring a method in outcome attribute as below,

<h:button value="GET button" outcome="#{bean.getOutcome()}" />

it will not be invoked when you click the button. Instead, it is already invoked when the page containing the button is rendered for the sole purpose to obtain the navigation outcome to be embedded in the generated onclick code. If you ever attempted to use the action method syntax as in outcome="#{bean.action}", you would already be hinted by this mistake/misconception by facing a javax.el.ELException: Could not find property actionMethod in class com.example.Bean.

If you intend to invoke a method as result of a POST request, use <h:commandButton> instead, see below. Or if you intend to invoke a method as result of a GET request, head to Invoke JSF managed bean action on page load or if you also have GET request parameters via <f:param>, How do I process GET query string URL parameters in backing bean on page load?

<h:commandButton>

The <h:commandButton> generates a HTML <input type="submit"> button which submits by default the parent <h:form> using HTTP POST method and invokes the actions attached to action, actionListener and/or <f:ajax listener>, if any. The <h:form> is required.

E.g.

<h:form id="form">
    <h:commandButton id="button" value="POST button" action="otherpage" />
</h:form>

will generate

<form id="form" name="form" method="post" action="/contextpath/currentpage.xhtml" enctype="application/x-www-form-urlencoded">
    <input type="hidden" name="form" value="form" />
    <input type="submit" name="form:button" value="POST button" />
    <input type="hidden" name="javax.faces.ViewState" id="javax.faces.ViewState" value="...." autocomplete="off" />
</form>

Note that it thus submits to the current page (the form action URL will show up in the browser address bar). It will afterwards forward to the target page, without any change in the URL in the browser address bar. You could add ?faces-redirect=true parameter to the outcome value to trigger a redirect after POST (as per the Post-Redirect-Get pattern) so that the target URL becomes bookmarkable.

The <h:commandButton> is usually exclusively used to submit a POST form, not to perform page-to-page navigation. Normally, the action points to some business action, such as saving the form data in DB, which returns a String outcome.

<h:commandButton ... action="#{bean.save}" />

with

public String save() {
    // ...
    return "otherpage";
}

Returning null or void will bring you back to the same view. Returning an empty string also, but it would recreate any view scoped bean. These days, with modern JSF2 and <f:ajax>, more than often actions just return to the same view (thus, null or void) wherein the results are conditionally rendered by ajax.

public void save() {
    // ...
}

it works for me Swift 3:

    func gestureRecognizer(_ gestureRecognizer: UIGestureRecognizer, shouldBeRequiredToFailBy otherGestureRecognizer: UIGestureRecognizer) -> Bool {
        return true
    }

and in ViewDidLoad:

    self.navigationController?.interactivePopGestureRecognizer?.delegate = self
    self.navigationController?.interactivePopGestureRecognizer?.isEnabled = true

This specific issue may arise in localhost also. We cannot rule out this is because network issue or internet connectivity issue. This issue will come even though all the database connection properties are correct.

I have faced the same issue when i have used host name. Instead use ip address. It will get resolved.

devnull's answer provides a function:

mkfile() { mkdir -p -- "$1" && touch -- "$1"/"$2" }

This function did not work for me as is (I'm running bash 4.3.48 on WSL Ubuntu), but did work once I removed the double dashes. So, this worked for me:

echo 'mkfile() { mkdir -p "$1" && touch "$1"/"$2" }' >> ~/.bash_profile
source ~/.bash_profile
mkfile sample/dir test.file

According to the api docs, doing:

dataFrame1.except(dataFrame2)

will return a new DataFrame containing rows in dataFrame1 but not in dataframe2.

Ermh... Came along here with exactly the same problem: Test a simple, but pivotal private method. After reading this thread, it appears to be like "I want to drill this simple hole in this simple piece of metal, and I want to make sure the quality meets the specs", and then comes "Okay, this is not to easy. First of all, there is no proper tool to do so, but you could build a gravitational-wave observatory in your garden. Read my article at http://foobar.brigther-than-einstein.org/ First, of course, you have to attend some advanced quantum physics courses, then you need tons of ultra-cool nitrogenium, and then, of course, my book available at Amazon"...

In other words...

No, first things first.

Each and every method, may it private, internal, protected, public has to be testable. There has to be a way to implement such tests without such ado as was presented here.

Why? Exactly because of the architectural mentions done so far by some contributors. Perhaps a simple reiteration of software principles may clear up some missunderstandings.

In this case, the usual suspects are: OCP, SRP, and, as always, KIS.

But wait a minute. The idea of making everything publicly available is more of less political and a kind of an attitude. But. When it comes to code, even in then Open Source Community, this is no dogma. Instead, "hiding" something is good practice to make it easier to come familiar with a certain API. You would hide, for example, the very core calculations of your new-to-market digital thermometer building block--not to hide the maths behind the real measured curve to curious code readers, but to prevent your code from becoming dependent on some, perhaps suddenly important users who could not resist using your formerly private, internal, protected code to implement their own ideas.

What am I talking about?

private double TranslateMeasurementIntoLinear(double actualMeasurement);

It's easy to proclaim the Age of Aquarius or what is is been called nowadays, but if my piece of sensor gets from 1.0 to 2.0, the implementation of Translate... might change from a simple linear equation that is easily understandable and "re-usable" for everybody, to a pretty sophisticated calculation that uses analysis or whatever, and so I would break other's code. Why? Because they didn't understand the very priciples of software coding, not even KIS.

To make this fairy tale short: We need a simple way to test private methods--without ado.

First: Happy new year everyone!

Second: Rehearse your architect lessons.

Third: The "public" modifier is religion, not a solution.

try this=> numpy.array(yourvariable) followed by the command to compare, whatever you wish to.

From the official Spring documentation:

General interface that represents binding results. Extends the interface for error registration capabilities, allowing for a Validator to be applied, and adds binding-specific analysis and model building.

Serves as result holder for a DataBinder, obtained via the DataBinder.getBindingResult() method. BindingResult implementations can also be used directly, for example to invoke a Validator on it (e.g. as part of a unit test).

I usually put all my files like that into an "assets" folder in the application root, and then I make sure to use an Asset_Helper to point to those files for me. This is what CodeIgniter suggests.

That is a C++ standard library header file for input output streams. It includes functionality to read and write from streams. You only need to include it if you wish to use streams.

Try this:

window.open(url, '_blank');

This will open in new tab (if your code is synchronous and in this case it is. in other case it would open a window)

inelegant (but effective) way: use percentages

#horizontal-style {
    width: 100%;
}

li {
    width: 20%;
}

This only works with the 5 <li> example. For more or less, modify your percentage accordingly. If you have other <li>s on your page, you can always assign these particular ones a class of "menu-li" so that only they are affected.

the best way (for me) to make it it's the next infrastructure:

<form method="POST">
<input type="submit" formaction="default_url_when_press_enter" style="visibility: hidden; display: none;">
<!-- all your inputs -->
<input><input><input>
<!-- all your inputs -->
<button formaction="action1">Action1</button>
<button formaction="action2">Action2</button>
<input type="submit" value="Default Action">
</form>

with this structure you will send with enter a direction and the infinite possibilities for the rest of buttons.

If you have your dates in DateTime variables, they don't have a format.

You can use the Date property to return a DateTime value with the time portion set to midnight. So, if you have:

DateTime dt1 = DateTime.Parse("07/12/2011");
DateTime dt2 = DateTime.Now;

if(dt1.Date > dt2.Date)
{
     //It's a later date
}
else
{
     //It's an earlier or equal date
}

It's important to distinguish two different formats:

• The RFC 3339/ISO 8601 "wire format": YYYY-MM-DD. According to the HTML5 specification, this is the format that must be used for the input's value upon form submission or when requested via the DOM API. It is locale and region independent.
• The format displayed by the user interface control and accepted as user input. Browser vendors are encouraged to follow the user's preferences selection. For example, on Mac OS with the region "United States" selected in the Language & Text preferences pane, Chrome 20 uses the format "m/d/yy".

The HTML5 specification does not include any means of overriding or manually specifying either format.

to add the original reference:

You can get the number of arguments from the special parameter $#. Value of 0 means "no arguments". $# is read-only.

When used in conjunction with shift for argument processing, the special parameter $# is decremented each time Bash Builtin shift is executed.

see Bash Reference Manual in section 3.4.2 Special Parameters:

• "The shell treats several parameters specially. These parameters may only be referenced"

• and in this section for keyword $# "Expands to the number of positional parameters in decimal."

You can either

fig, ax = plt.subplots()  #create figure and axes
candlestick(ax, quotes, ...)

or

candlestick(plt.gca(), quotes) #get the axis when calling the function

The first gives you more flexibility. The second is much easier if candlestick is the only thing you want to plot

You need to use a regular expression, so that you can specify the global (g) flag:

var s = 'some+multi+word+string'.replace(/\+/g, ' ');

(I removed the $() around the string, as replace is not a jQuery method, so that won't work at all.)

Just came across this trying to find a solution for the same problem. Implementing Paul's solution I've made a few tweaks to make this function properly.

var data = { 'venue[]' : []};

$("input:checked").each(function() {
   data['venue[]'].push($(this).val());
});

In short the addition of input:checked as opposed to :checked limits the fields input into the array to just the checkboxes on the form. Paul is indeed correct with this needing to be enclosed as $(this)

You can be guided by this example. On your css file:

.deskContent {
    background-image: url(../img/big-pic.png);
    width: 100%;
    height: 400px;
    background-repeat: no-repeat;
    background-size: contain; 
}

.phoneContent {
    background-image: url(../img/small-pic.png);
    width: 100%;
    height: 100px;
    background-repeat: no-repeat;
    background-size: contain;
}

@media all and (max-width: 959px) {
    .deskContent {display:block;}
    .phoneContent {display:none;}
}

@media all and (max-width: 479px) {
    .deskContent {display:none;}
    .phoneContent {display:block;}
}

On your html file:

<div class="deskContent">Content for desktop</div>
<div class="phoneContent">Content for mobile</div>

To create elements with equal width using Flex, you should set to your's child (flex elements):

flex-basis: 25%;
flex-grow: 0;

It will give to all elements in row 25% width. They will not grow and go one by one.

spark.default.parallelism is the default number of partition set by spark which is by default 200. and if you want to increase the number of partition than you can apply the property spark.sql.shuffle.partitions to set number of partition in the spark configuration or while running spark SQL.

Normally this spark.sql.shuffle.partitions it is being used when we have a memory congestion and we see below error: spark error:java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE

so set your can allocate a partition as 256 MB per partition and that you can use to set for your processes.

also If number of partitions is near to 2000 then increase it to more than 2000. As spark applies different logic for partition < 2000 and > 2000 which will increase your code performance by decreasing the memory footprint as data default is highly compressed if >2000.

First of all: I know this is rather old but there still is not an accepted answer, so perhaps my approach will help someone else. :)

What I did to solve this is:

process.Start();

while (true)
{
    try
    {
        var time = process.StartTime;
        break;
    }
    catch (Exception) {}
}

The association var time = process.StartTime will throw an exception as long as process did not start. So once it passes, it is safe to assume process is running and to work with it further. I am using this to wait for java process to start up, since it takes some time. This way it should be independent on what machine the application is running rather than using Thread.Sleep().

I understand this is not very clean solution, but the only one that should be performance independent I could think of.

TLDR; In addition to the accepted answer; One is implicit and one is explicit.

When the HTML you've written or had generated by an application/library/framework is read by your browser it will do it's best to interpret what your HTML meant (which can vary from browser to browser). When you use the HTML entity codes, you are being more specific to the browser. You are explicitly telling it you wish to display a character to the user (and not that you are just spacing your HTML for easier readability for the developer for instance).

To be more concrete, if the output HTML were:

<html>
   <title>hello</title>
   <body>
       <p>
           Tell me and I will forget. Teach me and I
           may remember.  Involve me and I will learn.
       </p>
   </body>
</html>

The browser would only render one space between all of these words (even the ones that have been indented for better developer readability.

If, however, you put the same thing and only changed the <p> tag to:

<p>Hello&nbsp;&nbsp;&nbsp;There</p>

Then it would render the spaces, as you've instructed it more explicitly. There is some history of using these spaces for styling. This use has somewhat been diminished as CSS has matured. However, there are still valid uses for many of the HTML character entities: avoiding unexpectedly/unintentionally interpretation (e.g. if you wanted to display code). The w3 has a great page to show the other character codes.

To get a user Input :

set /p pathName=Enter The Value:%=%
@echo %pathName%

p.s. this is also valid :

set /p pathName=Enter The Value:

Short Answer:

I did it. I wrote a function for dynamic usage for all the little people out there...

Working example which displays on the page

Working example logging to the console

Long Answer:

...Still did it.

It took me awhile to do it, since a psuedo element is not really on the page. While some of the answers above work in SOME scenarios, they ALL fail to be both dynamic and work in a scenario in which an element is both unexpected in size and position(such as absolute positioned elements overlaying a portion of the parent element). Mine does not.

Usage:

//some element selector and a click event...plain js works here too
$("div").click(function() {
    //returns an object {before: true/false, after: true/false}
    psuedoClick(this);

    //returns true/false
    psuedoClick(this).before;

    //returns true/false
    psuedoClick(this).after;

});

How it works:

It grabs the height, width, top, and left positions(based on the position away from the edge of the window) of the parent element and grabs the height, width, top, and left positions(based on the edge of the parent container) and compares those values to determine where the psuedo element is on the screen.

It then compares where the mouse is. As long as the mouse is in the newly created variable range then it returns true.

Note:

It is wise to make the parent element RELATIVE positioned. If you have an absolute positioned psuedo element, this function will only work if it is positioned based on the parent's dimensions(so the parent has to be relative...maybe sticky or fixed would work too....I dont know).

Code:

function psuedoClick(parentElem) {

    var beforeClicked,
      afterClicked;

  var parentLeft = parseInt(parentElem.getBoundingClientRect().left, 10),
      parentTop = parseInt(parentElem.getBoundingClientRect().top, 10);

  var parentWidth = parseInt(window.getComputedStyle(parentElem).width, 10),
      parentHeight = parseInt(window.getComputedStyle(parentElem).height, 10);

  var before = window.getComputedStyle(parentElem, ':before');

  var beforeStart = parentLeft + (parseInt(before.getPropertyValue("left"), 10)),
      beforeEnd = beforeStart + parseInt(before.width, 10);

  var beforeYStart = parentTop + (parseInt(before.getPropertyValue("top"), 10)),
      beforeYEnd = beforeYStart + parseInt(before.height, 10);

  var after = window.getComputedStyle(parentElem, ':after');

  var afterStart = parentLeft + (parseInt(after.getPropertyValue("left"), 10)),
      afterEnd = afterStart + parseInt(after.width, 10);

  var afterYStart = parentTop + (parseInt(after.getPropertyValue("top"), 10)),
      afterYEnd = afterYStart + parseInt(after.height, 10);

  var mouseX = event.clientX,
      mouseY = event.clientY;

  beforeClicked = (mouseX >= beforeStart && mouseX <= beforeEnd && mouseY >= beforeYStart && mouseY <= beforeYEnd ? true : false);

  afterClicked = (mouseX >= afterStart && mouseX <= afterEnd && mouseY >= afterYStart && mouseY <= afterYEnd ? true : false);

  return {
    "before" : beforeClicked,
    "after"  : afterClicked

  };      

}

Support:

I dont know....it looks like ie is dumb and likes to return auto as a computed value sometimes. IT SEEMS TO WORK WELL IN ALL BROWSERS IF DIMENSIONS ARE SET IN CSS. So...set your height and width on your psuedo elements and only move them with top and left. I recommend using it on things that you are okay with it not working on. Like an animation or something. Chrome works...as usual.

Not sure if this is still an issue for people, however... Using SystemJS and MomentJS as library, this solved it for me

/*
 * Import Custom Components
 */
import * as moment from 'moment/moment'; // please use path to moment.js file, extension is set in system.config

// under systemjs, moment is actually exported as the default export, so we account for that
const momentConstructor: (value?: any) => moment.Moment = (<any>moment).default || moment;

Works fine from there for me.

If you don't care about animation, then you don't have to get the height of the element. At least in all the browsers I've tried, if you give scrollTop a number that's bigger than the maximum, it'll just scroll to the bottom. So give it the biggest number possible:

$(myScrollingElement).scrollTop(Number.MAX_SAFE_INTEGER);

If you want to scroll the page, rather than some element with a scrollbar, just make myScrollingElement equal to 'body, html'.

Since I need to do this in several places, I've written a quick and dirty jQuery function to make it more convenient, like this:

(function($) {
  $.fn.scrollToBottom = function() {
    return this.each(function (i, element) {
      $(element).scrollTop(Number.MAX_SAFE_INTEGER);
    });
  };
}(jQuery));

So I can do this when I append a buncho' stuff:

$(myScrollingElement).append(lotsOfHtml).scrollToBottom();

Just to elaborate on the etymology of the command name rev-parse, Git consistently uses the term rev in plumbing commands as short for "revision" and generally meaning the 40-character SHA1 hash for a commit. The command rev-list for example prints a list of 40-char commit hashes for a branch or whatever.

In this case the name might be expanded to parse-a-commitish-to-a-full-SHA1-hash. While the command has the several ancillary functions mentioned in Tuxdude's answer, its namesake appears to be the use case of transforming a user-friendly reference like a branch name or abbreviated hash into the unambiguous 40-character SHA1 hash most useful for many programming/plumbing purposes.

I know I was thinking it was "reverse-parse" something for quite a while before I figured it out and had the same trouble making sense of the terms "massaging" and "manipulation" :)

Anyway, I find this "parse-to-a-revision" notion a satisfying way to think of it, and a reliable concept for bringing this command to mind when I need that sort of thing. Frequently in scripting Git you take a user-friendly commit reference as user input and generally want to get it resolved to a validated and unambiguous working reference as soon after receiving it as possible. Otherwise input translation and validation tends to proliferate through the script.

No matter how I tried, the errorlevel always stays 0 even when msbuild failed. So I built my workaround:

Build Project and save log to Build.log

SET Build_Opt=/flp:summary;logfile=Build.log;append=true

msbuild "myproj.csproj" /t:rebuild /p:Configuration=release /fl %Build_Opt%

search for "0 Error" string in build log, set the result to var

FOR /F "tokens=* USEBACKQ" %%F IN (`find /c /i "0 Error" Build.log`) DO (
    SET var=%%F
)
echo %var%

get the last character, which indicates how many lines contains the search string

set result=%var:~-1%

echo "%result%"

if string not found, then error > 0, build failed

if "%result%"=="0" ( echo "build failed" )

That solution was inspired by Mechaflash's post at How to set commands output as a variable in a batch file

and https://ss64.com/nt/syntax-substring.html

You are trying to run bash, an interactive shell that requires a tty in order to operate. It doesn't really make sense to run this in "detached" mode with -d, but you can do this by adding -it to the command line, which ensures that the container has a valid tty associated with it and that stdin remains connected:

docker run -it -d -p 52022:22 basickarl/docker-git-test

You would more commonly run some sort of long-lived non-interactive process (like sshd, or a web server, or a database server, or a process manager like systemd or supervisor) when starting detached containers.

If you are trying to run a service like sshd, you cannot simply run service ssh start. This will -- depending on the distribution you're running inside your container -- do one of two things:

• It will try to contact a process manager like systemd or upstart to start the service. Because there is no service manager running, this will fail.

• It will actually start sshd, but it will be started in the background. This means that (a) the service sshd start command exits, which means that (b) Docker considers your container to have failed, so it cleans everything up.

If you want to run just ssh in a container, consider an example like this.

If you want to run sshd and other processes inside the container, you will need to investigate some sort of process supervisor.

format supports a percentage floating point precision type:

>>> print "{0:.0%}".format(1./3)
33%

If you don't want integer division, you can import Python3's division from __future__:

>>> from __future__ import division
>>> 1 / 3
0.3333333333333333

# The above 33% example would could now be written without the explicit
# float conversion:
>>> print "{0:.0f}%".format(1/3 * 100)
33%

# Or even shorter using the format mini language:
>>> print "{:.0%}".format(1/3)
33%

You are trying to copy the war file to a directory below webapps. The war file should be copied into the webapps directory.

Remove the mkdir command, and copy the war file like this:

COPY /1.0-SNAPSHOT/my-app-1.0-SNAPSHOT.war /usr/local/tomcat/webapps/myapp.war

Tomcat will extract the war if autodeploy is turned on.

To me, handling exception can be seen as business rule. Obviously, the first approach is unacceptable. The second one is better one and it might be 100% correct way IF the context says so. Now, for example, you are developing an Outlook Addin. If you addin throws unhandled exception, the outlook user might now know it since the outlook will not destroy itself because of one plugin failed. And you have hard time to figure out what went wrong. Therefore, the second approach in this case, to me, it is a correct one. Beside logging the exception, you might decide to display error message to user - i consider it as a business rule.

If you receive this error after removing some gradle dependency, check your manifest and make sure that you removed all entries corresponding that dependency.

in Swift 3.0

yourView.backgroundColor = UIColor.black.withAlphaComponent(0.5)

This works for me in xcode 8.2.

It may helps you.

There are different ways in which properties can be overridden. Assuming you have

.left { background: blue }

e.g. any of the following would override it:

a.background-none { background: none; }
body .background-none { background: none; }
.background-none { background: none !important; }

The first two “win” by selector specificity; the third one wins by !important, a blunt instrument.

You could also organize your style sheets so that e.g. the rule

.background-none { background: none; }

wins simply by order, i.e. by being after an otherwise equally “powerful” rule. But this imposes restrictions and requires you to be careful in any reorganization of style sheets.

These are all examples of the CSS Cascade, a crucial but widely misunderstood concept. It defines the exact rules for resolving conflicts between style sheet rules.

P.S. I used left and background-none as they were used in the question. They are examples of class names that should not be used, since they reflect specific rendering and not structural or semantic roles.

Check STR. You need something like SELECT STR([Column_Name],10,0) ** This is SQL Server solution, for other servers check their docs.

Java 8 solution

If you would like a solution which:

• Utilizes Java 8 lambdas
• Does not depend on any JUnit magic
• Allows you to check for multiple exceptions within a single test method
• Checks for an exception being thrown by a specific set of lines within your test method instead of any unknown line in the entire test method
• Yields the actual exception object that was thrown so that you can further examine it

Here is a utility function that I wrote:

public final <T extends Throwable> T expectException( Class<T> exceptionClass, Runnable runnable )
{
    try
    {
        runnable.run();
    }
    catch( Throwable throwable )
    {
        if( throwable instanceof AssertionError && throwable.getCause() != null )
            throwable = throwable.getCause(); //allows "assert x != null : new IllegalArgumentException();"
        assert exceptionClass.isInstance( throwable ) : throwable; //exception of the wrong kind was thrown.
        assert throwable.getClass() == exceptionClass : throwable; //exception thrown was a subclass, but not the exact class, expected.
        @SuppressWarnings( "unchecked" )
        T result = (T)throwable;
        return result;
    }
    assert false; //expected exception was not thrown.
    return null; //to keep the compiler happy.
}

(taken from my blog)

Use it as follows:

@Test
public void testThrows()
{
    RuntimeException e = expectException( RuntimeException.class, () -> 
        {
            throw new RuntimeException( "fail!" );
        } );
    assert e.getMessage().equals( "fail!" );
}

I found I had to use both MutttenXd's and Badabam's CSS solutions together, as the first did not work in Chrome and the second did not work in Firefox:

a.anchor { 
  padding-top: 90px;
}

a.anchor:before { 
  display: block;
  content: "";
  height: 90px;
  margin-top: -90px;
}

<a class="anchor" name="shipping"></a><h2>Shipping (United States)</h2>
...

You could use serialize

<input type="hidden" name="quotation[]" value="{{serialize($quotation)}}">

But best way in this case use the json_encode method in your blade and json_decode in controller.

Your question is: are these not modules capable of declaring variables at global scope?

Answer: YES, they are "capable"

The only point is that references to global variables in ThisWorkbook or a Sheet module have to be fully qualified (i.e., referred to as ThisWorkbook.Global1, e.g.) References to global variables in a standard module have to be fully qualified only in case of ambiguity (e.g., if there is more than one standard module defining a variable with name Global1, and you mean to use it in a third module).

For instance, place in Sheet1 code

Public glob_sh1 As String

Sub test_sh1()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

place in ThisWorkbook code

Public glob_this As String

Sub test_this()
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

and in a Standard Module code

Public glob_mod As String

Sub test_mod()
    glob_mod = "glob_mod"
    ThisWorkbook.glob_this = "glob_this"
    Sheet1.glob_sh1 = "glob_sh1"
    Debug.Print (glob_mod)
    Debug.Print (ThisWorkbook.glob_this)
    Debug.Print (Sheet1.glob_sh1)
End Sub

All three subs work fine.

PS1: This answer is based essentially on info from here. It is much worth reading (from the great Chip Pearson).

PS2: Your line Debug.Print ("Hello") will give you the compile error Invalid outside procedure.

PS3: You could (partly) check your code with Debug -> Compile VBAProject in the VB editor. All compile errors will pop.

PS4: Check also Put Excel-VBA code in module or sheet?.

PS5: You might be not able to declare a global variable in, say, Sheet1, and use it in code from other workbook (reading http://msdn.microsoft.com/en-us/library/office/gg264241%28v=office.15%29.aspx#sectionSection0; I did not test this point, so this issue is yet to be confirmed as such). But you do not mean to do that in your example, anyway.

PS6: There are several cases that lead to ambiguity in case of not fully qualifying global variables. You may tinker a little to find them. They are compile errors.

dog.ts

import b = require('./baseTypes');

export module Living.Things {
    // Error, can't find name 'Animal', ??
    // Solved: can find, if properly referenced; exporting modules is useless, anyhow
    export class Dog extends b.Living.Things.Animal {
        public woof(): void {
            return;
        }
    }
}

tree.ts

// Error, can't use the same name twice, ??
// Solved: cannot declare let or const variable twice in same scope either: just use a different name
import b = require('./baseTypes');
import d = require('./dog');

module Living.Things {
    // Why do I have to write b.Living.Things.Plant instead of b.Plant??
    class Tree extends b.Living.Things.Plant {
    }
}

You have to update your

scanBasePackages = { "com.exm.java" }

to add the path to your service (after annotating it with @service )

You can also try this:

<div ng-init="myVar = 'www.thesoftdesign'">
        <h1>Tutorials</h1>
        <p>Go to <a ng-href="{{myVar}}">{{myVar}}</a> to learn!</p>
</div>

list comprehension formula:

[<value_when_condition_true> if <condition> else <value_when_condition_false> for value in list_name]

thus you can do it like this:

[y for y in a if y not in b]

Only for demonstration purpose : [y if y not in b else False for y in a ]

Quite simply, a "callable" is something that can be called like a method. The built in function "callable()" will tell you whether something appears to be callable, as will checking for a call property. Functions are callable as are classes, class instances can be callable. See more about this here and here.

    public static List getUniqueValues(List input) {
      return new ArrayList<>(new LinkedHashSet<>(incoming));
    }

dont forget to implement your equals method first

I think it's just because you have forgot HTTP METHOD. The default HTTP method of request is GET.

You should add method: 'POST' and your code will work if your backend receive the post method.

var req = require('request');

req.post({
   url: 'someUrl',
   form: { username: 'user', password: '', opaque: 'someValue', logintype: '1'},
   headers: { 
      'User-Agent': 'Mozilla/5.0 (Windows NT 6.1; WOW64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/27.0.1453.110 Safari/537.36',
      'Content-Type' : 'application/x-www-form-urlencoded' 
   },
   method: 'POST'
  },

  function (e, r, body) {
      console.log(body);
  });

In addtion to align-self you can also consider auto margin which will do almost the same thing

.container {_x000D_
  background: red;_x000D_
  height: 200px;_x000D_
  flex-direction: column;_x000D_
  padding: 10px;_x000D_
  display: flex;_x000D_
}_x000D_
a {_x000D_
  margin-right:auto;_x000D_
  padding: 10px 40px;_x000D_
  background: pink;_x000D_
}

<div class="container">_x000D_
  <a href="#">Test</a>_x000D_
</div>

If the aim is really to prevent multiple enumerations than the answer by Marc Gravell is the one to read, but maintaining the same semantics you could simple remove the redundant Any and First calls and go with:

public List<object> Foo(IEnumerable<object> objects)
{
    if (objects == null)
        throw new ArgumentNullException("objects");

    var first = objects.FirstOrDefault();

    if (first == null)
        throw new ArgumentException(
            "Empty enumerable not supported.", 
            "objects");

    var list = DoSomeThing(first);  

    var secondList = DoSomeThingElse(objects);

    list.AddRange(secondList);

    return list;
}

Note, that this assumes that you IEnumerable is not generic or at least is constrained to be a reference type.

This one worked for me:

>> print(df)
                          TotalVolume  Symbol
2016-04-15 09:00:00       108400       2802.T
2016-04-15 09:05:00       50300        2802.T

>> print(df.set_index(pd.to_datetime(df.index.values) - datetime(2016, 4, 15)))

             TotalVolume  Symbol
09:00:00     108400       2802.T
09:05:00     50300        2802.T

It looks like two of your lines are out of order. You start the process before setting up an event handler to capture the output. It's possible the process is just finishing before the event handler is added.

Switch the lines like so.

p.OutputDataReceived += ...
p.Start();        

var months = [
    {
        "updated_at" : "2012-01-01T06:25:24Z",
        "foo" : "bar"
    },
    {
        "updated_at" : "2012-01-09T11:25:13Z",
        "foo" : "bar"
    },
    {
        "updated_at" : "2012-01-05T04:13:24Z",
        "foo" : "bar"
    }];
months.sort((a, b)=>{
    var keyA = new Date(a.updated_at),
        keyB = new Date(b.updated_at);
    // Compare the 2 dates
    if(keyA < keyB) return -1;
    if(keyA > keyB) return 1;
    return 0;
});
console.log(months);

I believe that although javascript is an option here, you have a smoother animation through forcing hardware accelerate with CSS3. You can achieve this by setting the following CSS3 properties on the moving div:

div.hardware-accelarate {
     -webkit-transform: translate3d(0,0,0);
        -moz-transform: translate3d(0,0,0);
         -ms-transform: translate3d(0,0,0);
          -o-transform: translate3d(0,0,0);
             transform: translate3d(0,0,0);
}

I've made a plunkr setup for ya'll to test and tweak...

A lot of the answers here go the "use a framework" route. There's zero wrong with that. However I don't think it really answers your question, because frameworks may or may not use JSPs, nor are they designed in any way with removing java use in JSPs as a primary goal.

The only good answer to your question "how do I avoid using Java in a JSP" is: you can't.

That's what JSPs are for - using Java to render HTML with dynamic data/logic. The follow up question might be, how much java should I use in my JSPs.
Before we answer that question, you should also ponder, "do I need to use JSPs to build web content using Java?" The answer to that last one is, no. There are many alternatives to JSPs for developing web facing applications using Java. Struts for example does not force you to use JSPs - don't get me wrong, you can use them and many implementations do, but you don't absolutely have to. Struts doesn't even force you to use any HTML. A JSP doesn't either, but let's be honest, a JSP producing no HTML is kinda weird. Servlets, famously, allow you to serve any kind of content you like over HTTP dynamically. They are the primary tech behind pretty much everything java web - JSPs are just HTML templates for servlets, really.
So the answer to how much java you should put in a JSP is, "as little as possible". I of course have java in my JSPs, but it consists exclusively of tag library definitions, session and client variables, and beans encapsulating server side objects. The <%%> tags in my HTML are almost exclusively property calls or variable expressions. Rare exceptions include ultra-specific calculations pertaining to a single page and unlikely to ever be reused; bugfixes stemming from page-specific issues only applying to one page; last minute concatenations and arithmetic stemming from unusual requirements limited in scope to a single page; and other similar cases. In a code set of 1.5 million lines, 3000 JSPs and 5000 classes, there are maybe 100 instances of such unique snippets. It would have been quite possible to make these changes in classes or tag library definitions, but it would have been inordinately complex due to the specificity of each case, taken longer to write and debug, and taken more time as a result to get to my users. It's a judgement call. But make no mistake, you cannot write JSPs of any meaning with "no java" nor would you want to. The capability is there for a reason.

As of the Windows 10 "Anniversary" update (Version 1607), you can now run an Ubuntu subsystem from directly inside of Windows by enabling a feature called Developer mode.

To enable developer mode, go to Start > Settings then typing "Use developer features" in the search box to find the setting. On the left hand navigation, you will then see a tab titled For developers. From within this tab, you will see a radio box to enable Developer mode.

After developer mode is enabled, you will then be able to enable the Linux subsystem feature. To do so, go to Control Panel > Programs > Turn Windows features on or off > and check the box that says Windows Subsystem for Linux (Beta)

Now, rather than using Cygwin or a console emulator, you can run tmux through bash on the Ubuntu subsystem directly from Windows through the traditional apt package (sudo apt-get install tmux).

For documentation purpose, it's better to list the string values that are legal:

size: PropTypes.oneOfType([
    PropTypes.number,
    PropTypes.oneOf([ 'SMALL', 'LARGE' ]),
]),

If the string you have contains one, then you should use the other. For example, "You're able to do this", or 'He said "Hi!"'. Other than that, you should simply be as consistent as you can (within a module, within a package, within a project, within an organisation).

If your code is going to be read by people who work with C/C++ (or if you switch between those languages and Python), then using '' for single-character strings, and "" for longer strings might help ease the transition. (Likewise for following other languages where they are not interchangeable).

The Python code I've seen in the wild tends to favour " over ', but only slightly. The one exception is that """these""" are much more common than '''these''', from what I have seen.

The DateFormat class has a parse method.

See DateFormat for more information.

Make sure there is

127.0.0.1    localhost

Don't forget to update your iptables firewall if you have one to allow the 20-21 and 1024-1048 ranges in.

Do this from /etc/sysconfig/iptables

Adding lines like this:

-A INPUT -m state --state NEW -m tcp -p tcp --dport 20:21 -j ACCEPT

-A INPUT -m state --state NEW -m tcp -p tcp --dport 1024:1048 -j ACCEPT

And restart iptables with the command:

sudo service iptables restart

It's impossible without CSS. In fact, the <u> tag is simply adding text-decoration:underline to the text with the browser's built-in CSS.

Here's what you can do:

<html>
<head>
<!-- Other head stuff here, like title or meta -->

<style type="text/css">
u {    
    border-bottom: 1px dotted #000;
    text-decoration: none;
}
</style>
</head>
<!-- Body, content here -->
</html>

int variables can't be null

If a null is to be converted to int, then it is the converter which decides whether to set 0, throw exception, or set another value (like Integer.MIN_VALUE). Try to plug your own converter.

slightly improved version from milosmns...

public static String getPrettyXml(String xml) {
    if (xml == null || xml.trim().length() == 0) return "";

This is how i solved my problem

• go to xampp/mysql/data directory
• delete all the unwanted files except database folders
• restart the xampp server and go to the dashboard
• click the clear session data icon below the phpmyadmin icon

You are right, that test "and"s the two operands. But the result is discarded, the only thing that stays, and thats the important part, are the flags. They are set and thats the reason why the test instruction is used (and exist).

JE jumps not when equal (it has the meaning when the instruction before was a comparison), what it really does, it jumps when the ZF flag is set. And as it is one of the flags that is set by test, this instruction sequence (test x,x; je...) has the meaning that it is jumped when x is 0.

For questions like this (and for more details) I can just recommend a book about x86 instruction, e.g. even when it is really big, the Intel documentation is very good and precise.

Use setValue method of Range class to set the value of particular cell.

function storeValue() {
  var ss = SpreadsheetApp.getActiveSpreadsheet();
  // ss is now the spreadsheet the script is associated with
  var sheet = ss.getSheets()[0]; // sheets are counted starting from 0
  // sheet is the first worksheet in the spreadsheet
  var cell = sheet.getRange("B2"); 
  cell.setValue(100);
}

You can also select a cell using row and column numbers.

var cell = sheet.getRange(2, 3); // here cell is C2

It's also possible to set value of multiple cells at once.

var values = [
  ["2.000", "1,000,000", "$2.99"]
];

var range = sheet.getRange("B2:D2");
range.setValues(values);

Using children

const Wrapper = ({children}) => (
  <div>
    <div>header</div>
    <div>{children}</div>
    <div>footer</div>
  </div>
);

const App = ({name}) => <div>Hello {name}</div>;

const WrappedApp = ({name}) => (
  <Wrapper>
    <App name={name}/>
  </Wrapper>
);

render(<WrappedApp name="toto"/>,node);

This is also known as transclusion in Angular.

children is a special prop in React and will contain what is inside your component's tags (here <App name={name}/> is inside Wrapper, so it is the children

Note that you don't necessarily need to use children, which is unique for a component, and you can use normal props too if you want, or mix props and children:

const AppLayout = ({header,footer,children}) => (
  <div className="app">
    <div className="header">{header}</div>
    <div className="body">{children}</div>
    <div className="footer">{footer}</div>
  </div>
);

const appElement = (
  <AppLayout 
    header={<div>header</div>}
    footer={<div>footer</div>}
  >
    <div>body</div>
  </AppLayout>
);

render(appElement,node);

This is simple and fine for many usecases, and I'd recommend this for most consumer apps.

render props

It is possible to pass render functions to a component, this pattern is generally called render prop, and the children prop is often used to provide that callback.

This pattern is not really meant for layout. The wrapper component is generally used to hold and manage some state and inject it in its render functions.

Counter example:

const Counter = () => (
  <State initial={0}>
    {(val, set) => (
      <div onClick={() => set(val + 1)}>  
        clicked {val} times
      </div>
    )}
  </State>
); 

You can get even more fancy and even provide an object

<Promise promise={somePromise}>
  {{
    loading: () => <div>...</div>,
    success: (data) => <div>{data.something}</div>,
    error: (e) => <div>{e.message}</div>,
  }}
</Promise>

Note you don't necessarily need to use children, it is a matter of taste/API.

<Promise 
  promise={somePromise}
  renderLoading={() => <div>...</div>}
  renderSuccess={(data) => <div>{data.something}</div>}
  renderError={(e) => <div>{e.message}</div>}
/>

As of today, many libraries are using render props (React context, React-motion, Apollo...) because people tend to find this API more easy than HOC's. react-powerplug is a collection of simple render-prop components. react-adopt helps you do composition.

Higher-Order Components (HOC).

const wrapHOC = (WrappedComponent) => {
  class Wrapper extends React.PureComponent {
    render() {
      return (
        <div>
          <div>header</div>
          <div><WrappedComponent {...this.props}/></div>
          <div>footer</div>
        </div>
      );
    }  
  }
  return Wrapper;
}

const App = ({name}) => <div>Hello {name}</div>;

const WrappedApp = wrapHOC(App);

render(<WrappedApp name="toto"/>,node);

An Higher-Order Component / HOC is generally a function that takes a component and returns a new component.

Using an Higher-Order Component can be more performant than using children or render props, because the wrapper can have the ability to short-circuit the rendering one step ahead with shouldComponentUpdate.

Here we are using PureComponent. When re-rendering the app, if the WrappedApp name prop does not change over time, the wrapper has the ability to say "I don't need to render because props (actually, the name) are the same as before". With the children based solution above, even if the wrapper is PureComponent, it is not the case because the children element is recreated everytime the parent renders, which means the wrapper will likely always re-render, even if the wrapped component is pure. There is a babel plugin that can help mitigate this and ensure a constant children element over time.

Conclusion

Higher-Order Components can give you better performance. It's not so complicated but it certainly looks unfriendly at first.

Don't migrate your whole codebase to HOC after reading this. Just remember that on critical paths of your app you might want to use HOCs instead of runtime wrappers for performance reasons, particularly if the same wrapper is used a lot of times it's worth considering making it an HOC.

Redux used at first a runtime wrapper <Connect> and switched later to an HOC connect(options)(Comp) for performance reasons (by default, the wrapper is pure and use shouldComponentUpdate). This is the perfect illustration of what I wanted to highlight in this answer.

Note if a component has a render-prop API, it is generally easy to create a HOC on top of it, so if you are a lib author, you should write a render prop API first, and eventually offer an HOC version. This is what Apollo does with <Query> render-prop component, and the graphql HOC using it.

Personally, I use both, but when in doubt I prefer HOCs because:

• It's more idiomatic to compose them (compose(hoc1,hoc2)(Comp)) compared to render props
• It can give me better performances
• I'm familiar with this style of programming

I don't hesitate to use/create HOC versions of my favorite tools:

• React's Context.Consumer comp
• Unstated's Subscribe
• using graphql HOC of Apollo instead of Query render prop

In my opinion, sometimes render props make the code more readable, sometimes less... I try to use the most pragmatic solution according to the constraints I have. Sometimes readability is more important than performances, sometimes not. Choose wisely and don't bindly follow the 2018 trend of converting everything to render-props.

With all the undeniable benefits provided by inheritance, here's some of its disadvantages.

Disadvantages of Inheritance:

1. You can't change the implementation inherited from super classes at runtime (obviously because inheritance is defined at compile time).
2. Inheritance exposes a subclass to details of its parent class implementation, that's why it's often said that inheritance breaks encapsulation (in a sense that you really need to focus on interfaces only not implementation, so reusing by sub classing is not always preferred).
3. The tight coupling provided by inheritance makes the implementation of a subclass very bound up with the implementation of a super class that any change in the parent implementation will force the sub class to change.
4. Excessive reusing by sub-classing can make the inheritance stack very deep and very confusing too.

On the other hand Object composition is defined at runtime through objects acquiring references to other objects. In such a case these objects will never be able to reach each-other's protected data (no encapsulation break) and will be forced to respect each other's interface. And in this case also, implementation dependencies will be a lot less than in case of inheritance.

SELECT CAST(GETDATE() AS DATE)

Returns the current date with the time part removed.

DATETIMEs are not "stored in the following format". They are stored in a binary format.

SELECT CAST(GETDATE() AS BINARY(8))

The display format in the question is independent of storage.

Formatting into a particular display format should be done by your application.

If you are using windows, just search for miniconda and you'll find the folder. Go into the folder and you'll find a miniconda uninstall exe file. Run it.

You can use CSS3 to create an effect like that, but then you're only going to see it in modern browsers that support box shadow, unless you use a polyfill like CSS3PIE. So, for example, you could do something like this: http://jsfiddle.net/cany2/

Use LayoutBuilder and Get the output you want

Wrap the SingleChildScrollView with LayoutBuilder and implement the Builder function.

we can use a LayoutBuilder to get the box contains or the amount of space available.

LayoutBuilder(
    builder: (BuildContext context, BoxConstraints constraints){
      return SingleChildScrollView(
        child: Stack(
          children: <Widget>[
            Container(
              height: constraints.maxHeight,
            ),
            topTitle(context),
            middleView(context),
            bottomView(context),
          ],
        ),
      );
    }
)

I had a similar problem, I tried to clear all the caches possible (tried almost all the solutions above) and the only thing that worked for me was to kill the expo app and to restart it.

As Danack said in comments, there are 2 php.ini files. I uncommented the line with curl extension in the one in Apache folder, which is php.ini used by the web server.

Composer, on the other hand, uses php for console which is a whole different story. Php.ini file for that program is not the one in Apache folder but it's in the PHP folder and I had to uncomment the line in it too. Then I ran the installation again and it was OK.

Use dot notation and/or bracket notation to access object properties and for loops to iterate arrays:

var d, i;

for (i = 0; i < dictionary.data.length; i++) {
  d = dictionary.data[i];
  alert(d.id + ' ' + d.name);
}

You can also iterate arrays using for..in loops; however, properties added to Array.prototype may show through, and you may not necessarily get array elements in their correct order, or even in any consistent order.

Browser issue but can be solved by these:

<style type="text/css" media="print">
      @media print
      {
         @page {
           margin-top: 0;
           margin-bottom: 0;
         }
         body  {
           padding-top: 72px;
           padding-bottom: 72px ;
         }
      } 
</style>

Try setting the timeout value in your web service proxy class:

WebReference.ProxyClass myProxy = new WebReference.ProxyClass();
myProxy.Timeout = 100000; //in milliseconds, e.g. 100 seconds

The data from the request (content, inputs, files, querystring values) is all on this object HttpContext.Current.Request
To read the posted content

StreamReader reader = new StreamReader(HttpContext.Current.Request.InputStream);
string requestFromPost = reader.ReadToEnd();

To navigate through the all inputs

foreach (string key in HttpContext.Current.Request.Form.AllKeys)
{
   string value = HttpContext.Current.Request.Form[key];
}

You should not call a controller from the view.

Add a property to your view model, set it in the controller, and use it in the view.

Here is an example:

MyViewModel.cs:

public class MyViewModel
{   ...
    public bool ShowAdmin { get; set; }
}

MyController.cs:

public ViewResult GetAdminMenu()
    {
        MyViewModelmodel = new MyViewModel();            

        model.ShowAdmin = userHasPermission("Admin"); 

        return View(model);
    }

MyView.cshtml:

@model MyProj.ViewModels.MyViewModel


@if (@Model.ShowAdmin)
{
   <!-- admin links here-->
}

..\Views\Shared\ _Layout.cshtml:

    @using MyProj.ViewModels.Common;
....
    <div>    
        @Html.Action("GetAdminMenu", "Layout")
    </div>

hope it will help in jQuery

define a function first, if there is an existing function skip to next step.

 function someFun() {
 //use your code
 }

browser resize use like these.

 $(window).on('resize', function () {
    someFun();  //call your function.
 });

Don't waste your time trying to resolve this issue, this was made clear by the makers themselves. Instead of cv2.imshow() use this:

img = cv2.imread('path_to_image')
plt.imshow(img, cmap = 'gray', interpolation = 'bicubic')
plt.xticks([]), plt.yticks([])  # to hide tick values on X and Y axis
plt.show()

Date has the time as well, just add HH:mm:ss to the date format:

import java.text.SimpleDateFormat
def date = new Date()
def sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss")
println sdf.format(date)

In case you are using JRE 8 you can use LoaclDateTime:

import java.time.*

LocalDateTime t = LocalDateTime.now();
return t as String

Perhaps I'm missing something but why doesn't this work with the SEQUENCE object? Is this not what you're looking for?

Example:

CREATE SCHEMA blah.
GO

CREATE SEQUENCE blah.blahsequence
START WITH 1
INCREMENT BY 1
NO CYCLE;

CREATE TABLE blah.de_blah_blah
(numbers bigint PRIMARY KEY NOT NULL
......etc

When referencing the squence in say an INSERT command just use:

NEXT VALUE FOR blah.blahsequence

To avoid exceptions killing your app you should catch those exceptions and treat them the way you wish, defining the behavior for you app on those situations where the id is not found.

begin
  current_user.comments.find(ids)
rescue
  #do something in case of exception found
end

Here's more info on exceptions in ruby.

Consider whether you really need all this data explicitly, or can the matrix be sparse? There is good support in R (see Matrix package for e.g.) for sparse matrices.

Keep all other processes and objects in R to a minimum when you need to make objects of this size. Use gc() to clear now unused memory, or, better only create the object you need in one session.

If the above cannot help, get a 64-bit machine with as much RAM as you can afford, and install 64-bit R.

If you cannot do that there are many online services for remote computing.

If you cannot do that the memory-mapping tools like package ff (or bigmemory as Sascha mentions) will help you build a new solution. In my limited experience ff is the more advanced package, but you should read the High Performance Computing topic on CRAN Task Views.

Sure, you can open the devtools with Ctrl+Shift+I, and then click the inspect element button (square with the arrow)

First of all, if you open catalina.bat with text editor, you see that: "Do not set the variables in this script....." So never change it in that script, instead you can do below steps:

1. It advices you to create a new bat file with name "setenv.bat".

2. Then set 2 variables in that bat file such as:

   set CATALINA_OPTS="-Xdebug -Xrunjdwp:transport=dt_socket,address=8000,server=y,suspend=n"

   set JPDA_OPTS="-agentlib:jdwp=transport=dt_socket,address=8000,server=y,suspend=n"

3. Lastly run that at cmd that: "catalina.bat jpda start"

4. In IDE, create remote debug configuration and set host to related server ip and port to 8000.

sendmail works for me on the mac (10.6.8)

echo "Hello" | sendmail -f [email protected] [email protected]

You use it like this to redirect on a particular URL and render component after redirecting from old-router to new-router.

<Route path="/old-router">
  <Redirect exact to="/new-router"/>
  <Route path="/new-router" component={NewRouterType}/>
</Route>

you can use ls -1

ls -l will also do the work

You can create a Blob from your base64 data, and then read it asDataURL:

var img_b64 = canvas.toDataURL('image/png');
var png = img_b64.split(',')[1];

var the_file = new Blob([window.atob(png)],  {type: 'image/png', encoding: 'utf-8'});

var fr = new FileReader();
fr.onload = function ( oFREvent ) {
    var v = oFREvent.target.result.split(',')[1]; // encoding is messed up here, so we fix it
    v = atob(v);
    var good_b64 = btoa(decodeURIComponent(escape(v)));
    document.getElementById("uploadPreview").src = "data:image/png;base64," + good_b64;
};
fr.readAsDataURL(the_file);

Full example (includes junk code and console log): http://jsfiddle.net/tTYb8/

Alternatively, you can use .readAsText, it works fine, and its more elegant.. but for some reason text does not sound right ;)

fr.onload = function ( oFREvent ) {
    document.getElementById("uploadPreview").src = "data:image/png;base64,"
    + btoa(oFREvent.target.result);
};
fr.readAsText(the_file, "utf-8"); // its important to specify encoding here

Full example: http://jsfiddle.net/tTYb8/3/

As I understood in normal cases we are creating a table with Primary key which is having Identity property
So Rename or Delete a column which is associated with Primary Key constraint will not be possible because constraint Rules are validating column structure.
Tto achieve this we have to process some steps in the following way:
Let us assume TableName = 'Employee' and ColumnName = 'EmployeeId'

1. Add new column 'EmployeeId_new' in the 'Employee' table
ALTER TABLE Employee ADD EmployeeId_new INT IDENTITY(1,1)

2. Now remove column 'EmployeeId' from 'Employee' table
   ALTER TABLE Employee DROP COLUMN EmployeeId

3. This will throw error because of Primary Key Constraint rules are applicable and validating column structure.
   *### 'Msg 5074, Level 16, State 1, Line 1 The object [PK_dbo.Employee] is dependent on colmn [EmployeeId].'###

4. So we have to remove the Primary Key constraint first from the table 'Employee' then we can remove the column
   ALTER TABLE Employee DROP constraint [PK_dbo.Employee]

5. Now we can remove the column 'EmployeeId' from 'Employee' table as did in the previous step where we got error
   ALTER TABLE Employee DROP COLUMN EmployeeId

6. Now Column 'EmployeeId' removed from table So we will Rename the newly added new column 'EmployeeId_new' with 'EmployeeId'
   sp_rename 'Employee.EmployeeId', 'EmployeeId_new', 'COLUMN'

7. To rearrange the table in the same form as It was, we have to add Primary Key Constraint for the column 'EmployeeId'
   ALTER TABLE Employee add constraint [PK_dbo.Employee] primary key (EmployeeId)

8. Now the table 'Employee' with 'EmployeeId' is modified for Identity rules along with existing primary key constraint

To keep the code fluent (if code optimisation is not crucial) and you would need to do some further operations on the list:

authorsList = authorsList.Where(x => x.FirstName != "Bob").<do_some_further_Linq>;

or

authorsList = authorsList.Where(x => !setToRemove.Contains(x)).<do_some_further_Linq>;

Try adding return false; in your click callback like this -

$(document).ready(function() {
  $('.popup').click(function(event) {
      window.open($(this).attr("href"), "popupWindow", "width=600,height=600,scrollbars=yes");
      return false;
  });
});

Just FYI, you could use the VB.NET Like-Operator:

string text = "x is not the same as X and yz not the same as YZ";
bool contains = LikeOperator.LikeString(text,"*X*YZ*", Microsoft.VisualBasic.CompareMethod.Binary);  

Use CompareMethod.Text if you want to ignore the case.

You need to add using Microsoft.VisualBasic.CompilerServices;.

If you are using System.Web.Script.Serialization in the .NET framework you can put a ScriptIgnore attribute on the members that shouldn't be serialized. See the example taken from here:

Consider the following (simplified) case:

public class User {
    public int Id { get; set; }
    public string Name { get; set; }
    [ScriptIgnore]
    public bool IsComplete
    {
        get { return Id > 0 && !string.IsNullOrEmpty(Name); }
    } 
} 

In this case, only the Id and the Name properties will be serialized, thus the resulting JSON object would look like this:

{ Id: 3, Name: 'Test User' }

PS. Don't forget to add a reference to "System.Web.Extensions" for this to work

Your SVN passwords in Ubuntu (12.04) are in:

~/.subversion/auth/svn.simple/

However in newer versions they are encrypted, as earlier someone mentioned. To find gnome-keyring passwords, I suggest You to use 'gkeyring' program.

To install it on Ubuntu – add repository :

sudo add-apt-repository ppa:kampka/ppa
sudo apt-get update

Install it:

sudo apt-get install gkeyring

And run as following:

gkeyring --id 15 --output=name,secret

Try different key ids to find pair matching what you are looking for. Thanks to kampka for the soft.

jsonb in Postgres 9.4+

You can use the same query as below, just with jsonb_array_elements().

But rather use the jsonb "contains" operator @> in combination with a matching GIN index on the expression data->'objects':

CREATE INDEX reports_data_gin_idx ON reports
USING gin ((data->'objects') jsonb_path_ops);

SELECT * FROM reports WHERE data->'objects' @> '[{"src":"foo.png"}]';

Since the key objects holds a JSON array, we need to match the structure in the search term and wrap the array element into square brackets, too. Drop the array brackets when searching a plain record.

More explanation and options:

• Index for finding an element in a JSON array

json in Postgres 9.3+

Unnest the JSON array with the function json_array_elements() in a lateral join in the FROM clause and test for its elements:

SELECT data::text, obj
FROM   reports r, json_array_elements(r.data#>'{objects}') obj
WHERE  obj->>'src' = 'foo.png';

db<>fiddle here
_{Old sqlfiddle}

The CTE (WITH query) just substitutes for a table reports.
Or, equivalent for just a single level of nesting:

SELECT *
FROM   reports r, json_array_elements(r.data->'objects') obj
WHERE  obj->>'src' = 'foo.png';

->>, -> and #> operators are explained in the manual.

Both queries use an implicit JOIN LATERAL.

Closely related:

• Query for element of array in JSON column

This works for me without throwing an exception:

package com.sandbox;

import java.text.ParseException;
import java.text.SimpleDateFormat;
import java.util.Date;

public class Sandbox {

    public static void main(String[] args) throws ParseException {
        SimpleDateFormat format = new SimpleDateFormat("yyyyMMdd");
        Date parsed = format.parse("20110210");
        java.sql.Date sql = new java.sql.Date(parsed.getTime());
    }


}

Deleting all instances of *.exd resolved it for me.

This:

https://github.com/jbtule/cdto#cd-to

It's a small app that you drag into the Finder toolbar, the icon fits in very nicely. It works with Terminal, xterm (under X11), iterm.

If you don't have an array but you are trying to use your observable like an array even though it's a stream of objects, this won't work natively. I show how to fix this below assuming you only care about adding objects to the observable, not deleting them.

If you are trying to use an observable whose source is of type BehaviorSubject, change it to ReplaySubject then in your component subscribe to it like this:

Component

this.messages$ = this.chatService.messages$.pipe(scan((acc, val) => [...acc, val], []));

Html

<div class="message-list" *ngFor="let item of messages$ | async">

std::string a = "Hello ";
a += "World";

It depends on what you are trying to do.

file, err := os.Open("file.txt")
fmt.print(file)

The reason it outputs &{0xc082016240}, is because you are printing the pointer value of a file-descriptor (*os.File), not file-content. To obtain file-content, you may READ from a file-descriptor.

To read all file content(in bytes) to memory, ioutil.ReadAll

package main

import (
    "fmt"
    "io/ioutil"
    "os"
    "log"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


  b, err := ioutil.ReadAll(file)
  fmt.Print(b)
}

But sometimes, if the file size is big, it might be more memory-efficient to just read in chunks: buffer-size, hence you could use the implementation of io.Reader.Read from *os.File

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()


    buf := make([]byte, 32*1024) // define your buffer size here.

    for {
        n, err := file.Read(buf)

        if n > 0 {
            fmt.Print(buf[:n]) // your read buffer.
        }

        if err == io.EOF {
            break
        }
        if err != nil {
            log.Printf("read %d bytes: %v", n, err)
            break
        }
    }

}

Otherwise, you could also use the standard util package: bufio, try Scanner. A Scanner reads your file in tokens: separator.

By default, scanner advances the token by newline (of course you can customise how scanner should tokenise your file, learn from here the bufio test).

package main

import (
    "fmt"
    "os"
    "log"
    "bufio"
)

func main() {
    file, err := os.Open("file.txt")
    if err != nil {
        log.Fatal(err)
    }
    defer func() {
        if err = f.Close(); err != nil {
            log.Fatal(err)
        }
    }()

    scanner := bufio.NewScanner(file)

    for scanner.Scan() {             // internally, it advances token based on sperator
        fmt.Println(scanner.Text())  // token in unicode-char
        fmt.Println(scanner.Bytes()) // token in bytes

    }
}

Lastly, I would also like to reference you to this awesome site: go-lang file cheatsheet. It encompassed pretty much everything related to working with files in go-lang, hope you'll find it useful.

You can use assign_attributes or attributes= (they're the same)

Update methods cheat sheet (for Rails 6):

• update = assign_attributes + save
• attributes= = alias of assign_attributes
• update_attributes = deprecated, alias of update

Source:
https://github.com/rails/rails/blob/master/activerecord/lib/active_record/persistence.rb
https://github.com/rails/rails/blob/master/activerecord/lib/active_record/attribute_assignment.rb

Another cheat sheet:
http://www.davidverhasselt.com/set-attributes-in-activerecord/#cheat-sheet

The solutions so far are all quite complicated. The idiomatic solution should doubtless be:

String.Join(",", x.Cast(Of String)().ToArray())

There's no need for fancy acrobatics in new framework versions. Supposing a not-so-modern version, the following would be easiest:

Console.WriteLine(String.Join(",", CType(x.ToArray(GetType(String)), String())))

mspmsp's second solution is a nice approach as well but it's not working because it misses the AddressOf keyword. Also, Convert.ToString is rather inefficient (lots of unnecessary internal evaluations) and the Convert class is generally not very cleanly designed. I tend to avoid it, especially since it's completely redundant.

df.to_html() has a columns parameter.

Just pass the columns into the to_html() method.

df.to_html(columns=['A','B','C','D','E','F','G'])

I prefer @Ista solution, cause needs no extra package and is simple.
A modification of the data.table solution also solve my problem, and is more general.
My data.frame is

> str(df)
'data.frame':   579 obs. of  11 variables:
 $ trees     : num  2000 5000 1000 2000 1000 1000 2000 5000 5000 1000 ...

 $ shrinkage : num  0.01 0.001 0.01 0.005 0.01 0.01 0.001 0.005 0.005 0.001     ...

The data.table solution needs order on i to do the job:

> require(data.table)
> dt1 <- data.table(df)
> dt2 = dt1[order(-efet, G1, G2), head(.SD, 3), by = .(G1, G2)]
> dt2
    G1    G2 trees interDepth minObs shrinkage        qx   efet  prec  sens   acu

By some reason, it does not order the way pointed (probably because ordering by the groups). So, another ordering is done.

There is no need for jQuery here, regular JavaScript will do:

var str = "Abc: Lorem ipsum sit amet";
str = str.substring(str.indexOf(":") + 1);

Or, the .split() and .pop() version:

var str = "Abc: Lorem ipsum sit amet";
str = str.split(":").pop();

Or, the regex version (several variants of this):

var str = "Abc: Lorem ipsum sit amet";
str = /:(.+)/.exec(str)[1];

Set elevation: 3 and you should see the shadow in bottom of component without a 3rd party lib. At least in RN 0.57.4

Not sure if this is what you're after, but it will loop through the range that you gave it and if it finds an "A" it will remove it from the cell. I'm not sure what oldStr is used for...

Private Sub foo()
Dim myString As String
RowCount = WorksheetFunction.CountA(Range("A:A"))

For i = 2 To RowCount
    myString = Trim(Cells(i, 1).Value)
    If InStr(myString, "A") > 0 Then
        Cells(i, 1).Value = Left(myString, InStr(myString, "A"))
    End If
Next
End Sub

I'm adding this second answer based on a proposed edit by user srborlongan to my other answer. I think the technique proposed was interesting, but it wasn't really suitable as an edit to my answer. Others agreed and the proposed edit was voted down. (I wasn't one of the voters.) The technique has merit, though. It would have been best if srborlongan had posted his/her own answer. This hasn't happened yet, and I didn't want the technique to be lost in the mists of the StackOverflow rejected edit history, so I decided to surface it as a separate answer myself.

Basically the technique is to use some of the Optional methods in a clever way to avoid having to use a ternary operator (? :) or an if/else statement.

My inline example would be rewritten this way:

Optional<Other> result =
    things.stream()
          .map(this::resolve)
          .flatMap(o -> o.map(Stream::of).orElseGet(Stream::empty))
          .findFirst();

An my example that uses a helper method would be rewritten this way:

/**
 * Turns an Optional<T> into a Stream<T> of length zero or one depending upon
 * whether a value is present.
 */
static <T> Stream<T> streamopt(Optional<T> opt) {
    return opt.map(Stream::of)
              .orElseGet(Stream::empty);
}

Optional<Other> result =
    things.stream()
          .flatMap(t -> streamopt(resolve(t)))
          .findFirst();

COMMENTARY

Let's compare the original vs modified versions directly:

// original
.flatMap(o -> o.isPresent() ? Stream.of(o.get()) : Stream.empty())

// modified
.flatMap(o -> o.map(Stream::of).orElseGet(Stream::empty))

The original is a straightforward if workmanlike approach: we get an Optional<Other>; if it has a value, we return a stream containing that value, and if it has no value, we return an empty stream. Pretty simple and easy to explain.

The modification is clever and has the advantage that it avoids conditionals. (I know that some people dislike the ternary operator. If misused it can indeed make code hard to understand.) However, sometimes things can be too clever. The modified code also starts off with an Optional<Other>. Then it calls Optional.map which is defined as follows:

If a value is present, apply the provided mapping function to it, and if the result is non-null, return an Optional describing the result. Otherwise return an empty Optional.

The map(Stream::of) call returns an Optional<Stream<Other>>. If a value was present in the input Optional, the returned Optional contains a Stream that contains the single Other result. But if the value was not present, the result is an empty Optional.

Next, the call to orElseGet(Stream::empty) returns a value of type Stream<Other>. If its input value is present, it gets the value, which is the single-element Stream<Other>. Otherwise (if the input value is absent) it returns an empty Stream<Other>. So the result is correct, the same as the original conditional code.

In the comments discussing on my answer, regarding the rejected edit, I had described this technique as "more concise but also more obscure". I stand by this. It took me a while to figure out what it was doing, and it also took me a while to write up the above description of what it was doing. The key subtlety is the transformation from Optional<Other> to Optional<Stream<Other>>. Once you grok this it makes sense, but it wasn't obvious to me.

I'll acknowledge, though, that things that are initially obscure can become idiomatic over time. It might be that this technique ends up being the best way in practice, at least until Optional.stream gets added (if it ever does).

UPDATE: Optional.stream has been added to JDK 9.

You can achieve the desired result by requesting a list of distinct ids instead of a list of distinct hydrated objects.

Simply add this to your criteria:

criteria.setProjection(Projections.distinct(Projections.property("id")));

Now you'll get the correct number of results according to your row-based limiting. The reason this works is because the projection will perform the distinctness check as part of the sql query, instead of what a ResultTransformer does which is to filter the results for distinctness after the sql query has been performed.

Worth noting is that instead of getting a list of objects, you will now get a list of ids, which you can use to hydrate objects from hibernate later.

You should amend creation of the gesture recogniser to accept parameter (add colon ':')

UITapGestureRecognizer *letterTapRecognizer = [[UITapGestureRecognizer alloc] initWithTarget:self action:@selector(highlightLetter:)];

And in your method highlightLetter: you can access the view attached to recogniser:

-(IBAction) highlightLetter:(UITapGestureRecognizer*)recognizer
{
    UIView *view = [recognizer view];
}

This solved my problem, from preventign that an event gets fired by a children:

doSmth(){_x000D_
  // what ever_x000D_
}

        <div (click)="doSmth()">_x000D_
            <div (click)="$event.stopPropagation()">_x000D_
                <my-component></my-component>_x000D_
            </div>_x000D_
        </div>

Since you're talking about financial figures, you DO NOT WANT to use floating-point arithmetic. You're better off using Decimal.

>>> from decimal import Decimal
>>> Decimal("33.505")
Decimal('33.505')

Text output formatting with new-style format() (defaults to half-even rounding):

>>> print("financial return of outcome 1 = {:.2f}".format(Decimal("33.505")))
financial return of outcome 1 = 33.50
>>> print("financial return of outcome 1 = {:.2f}".format(Decimal("33.515")))
financial return of outcome 1 = 33.52

See the differences in rounding due to floating-point imprecision:

>>> round(33.505, 2)
33.51
>>> round(Decimal("33.505"), 2)  # This converts back to float (wrong)
33.51
>>> Decimal(33.505)  # Don't init Decimal from floating-point
Decimal('33.50500000000000255795384873636066913604736328125')

Proper way to round financial values:

>>> Decimal("33.505").quantize(Decimal("0.01"))  # Half-even rounding by default
Decimal('33.50')

It is also common to have other types of rounding in different transactions:

>>> import decimal
>>> Decimal("33.505").quantize(Decimal("0.01"), decimal.ROUND_HALF_DOWN)
Decimal('33.50')
>>> Decimal("33.505").quantize(Decimal("0.01"), decimal.ROUND_HALF_UP)
Decimal('33.51')

Remember that if you're simulating return outcome, you possibly will have to round at each interest period, since you can't pay/receive cent fractions, nor receive interest over cent fractions. For simulations it's pretty common to just use floating-point due to inherent uncertainties, but if doing so, always remember that the error is there. As such, even fixed-interest investments might differ a bit in returns because of this.

You will find multiple different methods that people use and they each have there own place.

<?php if($first_condition): ?>
  /*$first_condition is true*/
<?php elseif ($second_condition): ?>
  /*$first_condition is false and $second_condition is true*/
<?php else: ?>
  /*$first_condition and $second_condition are false*/
<?php endif; ?>

If in your php.ini attribute short_open_tag = true (this is normally found on line 141 of the default php.ini file) you can replace your php open tag from <?php to <?. This is not advised as most live server environments have this turned off (including many CMS's like Drupal, WordPress and Joomla). I have already tested short hand open tags in Drupal and confirmed that it will break your site, so stick with <?php. short_open_tag is not on by default in all server configurations and must not be assumed as such when developing for unknown server configurations. Many hosting companies have short_open_tag turned off.

A quick search of short_open_tag in stackExchange shows 830 results. https://stackoverflow.com/search?q=short_open_tag That's a lot of people having problems with something they should just not play with.

with some server environments and applications, short hand php open tags will still crash your code even with short_open_tag set to true.

short_open_tag will be removed in PHP6 so don't use short hand tags.

all future PHP versions will be dropping short_open_tag

• https://softwareengineering.stackexchange.com/questions/151661/is-it-bad-practice-to-use-tag-in-php

"It's been recommended for several years that you not use the short tag "short cut" and instead to use the full tag combination. With the wide spread use of XML and use of these tags by other languages, the server can become easily confused and end up parsing the wrong code in the wrong context. But because this short cut has been a feature for such a long time, it's currently still supported for backwards compatibility, but we recommend you don't use them." – Jelmer Sep 25 '12 at 9:00 php: "short_open_tag = On" not working

and

Normally you write PHP like so: . However if allow_short_tags directive is enabled you're able to use: . Also sort tags provides extra syntax: which is equal to .

Short tags might seem cool but they're not. They causes only more problems. Oh... and IIRC they'll be removed from PHP6. Crozin answered Aug 24 '10 at 22:12 php short_open_tag problem

and

To answer the why part, I'd quote Zend PHP 5 certification guide: "Short tags were, for a time, the standard in the PHP world; however, they do have the major drawback of conflicting with XML headers and, therefore, have somewhat fallen by the wayside." – Fluffy Apr 13 '11 at 14:40 Are PHP short tags acceptable to use?

You may also see people use the following example:

<?php if($first_condition){ ?>
  /*$first_condition is true*/
<?php }else if ($second_condition){ ?>
  /*$first_condition is false and $second_condition is true*/
<?php }else{ ?>
  /*$first_condition and $second_condition are false*/
<?php } ?>

This will work but it is highly frowned upon as it's not considered as legible and is not what you would use this format for. If you had a PHP file where you had a block of PHP code that didn't have embedded tags inside, then you would use the bracket format.

The following example shows when to use the bracket method

<?php
if($first_condition){
   /*$first_condition is true*/
}else if ($second_condition){
   /*$first_condition is false and $second_condition is true*/
}else{
   /*$first_condition and $second_condition are false*/
}
?>

If you're doing this code for yourself you can do what you like, but if your working with a team at a job it is advised to use the correct format for the correct circumstance. If you use brackets in embedded html/php scripts that is a good way to get fired, as no one will want to clean up your code after you. IT bosses will care about code legibility and college professors grade on legibility.

UPDATE

based on comments from duskwuff its still unclear if shorthand is discouraged (by the php standards) or not. I'll update this answer as I get more information. But based on many documents found on the web about shorthand being bad for portability. I would still personally not use it as it gives no advantage and you must rely on a setting being on that is not on for every web host.

This is the answer if someone want to know

if (Date.now() >= exp * 1000) {
  return false;
}

Also I think if_exists was used like:

Hi ${userName?if_exists}, How are you?

which will not break if userName is null, the result if null would be:

Hi , How are you?

if_exists is now deprecated and has been replaced with the default operator ! as in

Hi ${userName!}, How are you?

the default operator also supports a default value, such as:

Hi ${userName!"John Doe"}, How are you?

You could use inline styles and define the width in the <th> tag. Make it so that the sum of the widths = 100%.

    <tr>
        <th style="width:10%">Size</th>
        <th style="width:30%">Bust</th>
        <th style="width:50%">Waist</th>
        <th style="width:10%">Hips</th>
    </tr>

Bootply demo

Typically using inline styles is not ideal, however this does provide flexibility because you can get very specific and granular with exact widths.

As far as i know that is impossible and that makes sense since what you are trying to do is against the idea of tabular data presentation. You could however put the data in multiple tables and remove any padding and margins in between them to achieve the same result, at least visibly. Something along the lines of:

I don't know your requirements but i'm sure there's a more elegant solution.

Change position

position:fixed;
overflow: hidden;

to

position:absolute;
overflow:scroll;

The only commands that worked for me were:

git fetch --all
git reset --hard origin/{{your branch name}}

In case you have Git installed,

you can open the Git Bash (shift pressed + right click in the folder -> Git Bash Here) and use openssl command right in the Bash

In general, you can use a backslash at the end of a line in order for the command to continue on to the next line. However, there are cases where commands are implicitly continued, namely when the line ends with a token than cannot legally terminate a command. In that case, the shell knows that more is coming, and the backslash can be omitted. Some examples:

# In general
$ echo "foo" \
> "bar"
foo bar

# Pipes
$ echo foo |
> cat
foo

# && and ||
$ echo foo &&
> echo bar
foo
bar
$ false ||
> echo bar
bar

Different, but related, is the implicit continuation inside quotes. In this case, without a backslash, you are simply adding a newline to the string.

$ x="foo
> bar"
$ echo "$x"
foo
bar

With a backslash, you are again splitting the logical line into multiple logical lines.

$ x="foo\
> bar"
$ echo "$x"
foobar

JavaScript objects cannot be implemented purely on top of hash maps.

Try this in your browser console:

var foo = {
    a: true,
    b: true,
    z: true,
    c: true
}

for (var i in foo) {
    console.log(i);
}

...and you'll recieve them back in insertion order, which is de facto standard behaviour.

Hash maps inherently do not maintain ordering, so JavaScript implementations may use hash maps somehow, but if they do, it'll require at least a separate index and some extra book-keeping for insertions.

Here's a video of Lars Bak explaining why v8 doesn't use hash maps to implement objects.

grep -l 

(That's a lowercase L)

Similar issue, using this "borrowed" and slightly modified code:

                Intent intent = new Intent(Intent.ACTION_VIEW);
                File newApk = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS) + "myapp.apk");
                intent.setDataAndType(Uri.fromFile(newApk), "application/vnd.android.package-archive");
                intent.setFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                startActivity(intent);
                result = true;

Needed to change the file creation to this (comma instead of plus in the File constructor, was missing '/' after the download directory):

                    File newApk = new File(Environment.getExternalStoragePublicDirectory(Environment.DIRECTORY_DOWNLOADS), "myapp.apk");

First run your IDE or CMD as Administrator and run the following:

pip install pipwin
pipwin install pyaudio

One way to handle this is to put the information as an attribute on the primary one. I must stress, I really think this is the appropriate thing to do only when the two pieces of information are related such that one has information about the other.

For example, I sometimes stash the name of "crucial variables" or variables that have been significantly modified by storing a list of variable names as an attribute on the data frame:

attr(my.DF, 'Modified.Variables') <- DVs.For.Analysis$Names.of.Modified.Vars
return(my.DF)

This allows me to store a list of variable names with the data frame itself.

You can try using USING:

The optional USING clause specifies how to compute the new column value from the old; if omitted, the default conversion is the same as an assignment cast from old data type to new. A USING clause must be provided if there is no implicit or assignment cast from old to new type.

So this might work (depending on your data):

alter table presales alter column code type numeric(10,0) using code::numeric;
-- Or if you prefer standard casting...
alter table presales alter column code type numeric(10,0) using cast(code as numeric);

This will fail if you have anything in code that cannot be cast to numeric; if the USING fails, you'll have to clean up the non-numeric data by hand before changing the column type.

I hope this will work

You could use imagemagick and write a script that fires everytime you load a webpage.

SQLTools is an almost fully functional and free Oracle GUI:

Here is the JSfiddle Demo

I changed your HTML and give your input textfield an id of value. I removed the passed param for your verifyorder function, and instead grab the content of your textfield by using document.getElementById(); then i convert the str into value with +order so you can check if it's greater than zero:

<input type="text" maxlength="3" name="value" id='value' />
<input type="button" value="submit" onclick="verifyorder()" />
</p>
<p id="error"></p>
<p id="detspace"></p> 

function verifyorder() {
        var order = document.getElementById('value').value;
        if (+order > 0) {
            alert(+order);
            return true;
        }
        else {
            alert("Sorry, you need to enter a positive integer value, try again");
            document.getElementById('error').innerHTML = "Sorry, you need to enter a positive integer value, try again";
        }
    }

Use \nolinebreak

\nolinebreak[number]

The \nolinebreak command prevents LaTeX from breaking the current line at the point of the command. With the optional argument, number, you can convert the \nolinebreak command from a demand to a request. The number must be a number from 0 to 4. The higher the number, the more insistent the request is.

Try:

awk -F',' '{print $3}' myfile.txt

Here in -F you are saying to awk that use "," as field separator.

I had this problem and found that removing the following folder helped, even with the non-Express edition.Express:

C:\Users\<user>\Documents\IISExpress

This is really just an expansion of BBB's answer which lead to to get my experiment working.

This script will simply create a file /tmp/testfile when you click on the button that says "Open Script".

This requires 3 files.

1. The actual HTML Website with a button.
2. A php script which executes the script
3. A Script

The File Tree:

root@test:/var/www/html# tree testscript/
testscript/
+-- index.html
+-- testexec.php
+-- test.sh

1. The main WebPage:

root@test:/var/www/html# cat testscript/index.html
<form action="/testscript/testexec.php">
    <input type="submit" value="Open Script">
</form>

2. The PHP Page that runs the script and redirects back to the main page:

root@test:/var/www/html# cat testscript/testexec.php
<?php
shell_exec("/var/www/html/testscript/test.sh");
header('Location: http://192.168.1.222/testscript/index.html?success=true');
?>

3. The Script :

root@test:/var/www/html# cat testscript/test.sh

#!/bin/bash

touch /tmp/testfile

I'm going to assume your host is using C-Panel - and that it's probably HostGator or GoDaddy. In both cases they use C-Panel (in fact, a lot of hosts do) to make the Server administration as easy as possible on you, the end user. Even if you are hosting through someone else - see if you can log in to some kind of admin panel and find an .htaccess file that you can edit. (Note: The period before just means that it's a "hidden" file/directory).

Once you find the htaccess file add the following line:

1. Header set Access-Control-Allow-Origin "*" Just to see if it works. Warning: Do not use this line on a production server

It should work. If not, call your host and ask them why the line isn't working - they'll probably be able to help you quickly from there.

2. Once you do have the above working change the * to the address of the requesting domain http://cyclistinsuranceaustralia.com.au/. You may find an issue with canonical addressing (including the www) and if so you may need to configure your host for a redirect. That's a different and smaller bridge to cross though. You'll at least be in the right place.

Reading the json rfc (http://www.ietf.org/rfc/rfc4627.txt) it is clear that the preferred encoding is utf-8.

FYI, RFC 4627 is no longer the official JSON spec. It was obsoleted in 2014 by RFC 7159, which was then obsoleted in 2017 by RFC 8259, which is the current spec.

RFC 8259 states:

8.1. Character Encoding

JSON text exchanged between systems that are not part of a closed ecosystem MUST be encoded using UTF-8 [RFC3629].

Previous specifications of JSON have not required the use of UTF-8 when transmitting JSON text. However, the vast majority of JSON-based software implementations have chosen to use the UTF-8 encoding, to the extent that it is the only encoding that achieves interoperability.

Implementations MUST NOT add a byte order mark (U+FEFF) to the beginning of a networked-transmitted JSON text. In the interests of interoperability, implementations that parse JSON texts MAY ignore the presence of a byte order mark rather than treating it as an error.

try this

  function sum() {
       var txtFirstNumberValue = document.getElementById('txt1').value;
       var txtSecondNumberValue = document.getElementById('txt2').value;
       if (txtFirstNumberValue == "")
           txtFirstNumberValue = 0;
       if (txtSecondNumberValue == "")
           txtSecondNumberValue = 0;

       var result = parseInt(txtFirstNumberValue) + parseInt(txtSecondNumberValue);
       if (!isNaN(result)) {
           document.getElementById('txt3').value = result;
       }
   }

I use SwitchToThisWindow to bring the application to the forefront as in this example:

static class Program
{
    [DllImport("User32.dll", SetLastError = true)]
    static extern void SwitchToThisWindow(IntPtr hWnd, bool fAltTab);



    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        bool createdNew;
        int iP;
        Process currentProcess = Process.GetCurrentProcess();
        Mutex m = new Mutex(true, "XYZ", out createdNew);
        if (!createdNew)
        {
            // app is already running...
            Process[] proc = Process.GetProcessesByName("XYZ");

            // switch to other process
            for (iP = 0; iP < proc.Length; iP++)
            {
                if (proc[iP].Id != currentProcess.Id)
                    SwitchToThisWindow(proc[0].MainWindowHandle, true);
            }

            return;
        }

        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new form());
        GC.KeepAlive(m);

    }

If the previous answers do not solve your problem, check the source of the data that won't print/convert properly.

In my case, I was using json.load on data incorrectly read from file by not using the encoding="utf-8". Trying to de-/encode the resulting string to latin-1 just does not help...

I usually write in such style :

<a class="btn" ng-click="remove($index)">Delete</a>


$scope.remove = function(index){
  $scope.[yourArray].splice(index, 1)
};

Hope this will help You have to use a dot(.) between $scope and [yourArray]

AkashG's solution don't work for me. When I set up check.xml to background it's just stratched in vertical direction. To solve this problem you should set up check.xml to "android:button" property:

<ToggleButton 
    android:id="@+id/toggle"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:button="@drawable/check"   //check.xml
    android:background="@null"/>

check.xml:

<?xml version="1.0" encoding="utf-8"?>
    <selector xmlns:android="http://schemas.android.com/apk/res/android">
    <!-- When selected, use grey -->
    <item android:drawable="@drawable/selected_image"
          android:state_checked="true" />
    <!-- When not selected, use white-->
    <item android:drawable="@drawable/unselected_image"
          android:state_checked="false"/>
    </selector>

ToAddress = "[email protected]"
ToAddress1 = "[email protected]"
ToAddress2 = "[email protected]"
MessageSubject = "It works!."
Set ol = CreateObject("Outlook.Application")
Set newMail = ol.CreateItem(olMailItem)
newMail.Subject = MessageSubject
newMail.RecipIents.Add(ToAddress)
newMail.RecipIents.Add(ToAddress1)
newMail.RecipIents.Add(ToAddress2)
newMail.Send

If your XSLT processor supports EXSLT, you can use str:tokenize, otherwise, the link contains an implementation using functions like substring-before.

I haven't found the solution that would handle names with 3 or more components and support older iOS versions.

struct NameComponentsSplitter {

    static func split(fullName: String) -> (String?, String?) {
        guard !fullName.isEmpty else {
            return (nil, nil)
        }
        let components = fullName.components(separatedBy: .whitespacesAndNewlines)
        let lastName = components.last
        let firstName = components.dropLast().joined(separator: " ")
        return (firstName.isEmpty ? nil : firstName, lastName)
    }
}

Passed test cases:

func testThatItHandlesTwoComponents() {
    let (firstName, lastName) = NameComponentsSplitter.split(fullName: "John Smith")
    XCTAssertEqual(firstName, "John")
    XCTAssertEqual(lastName, "Smith")
}

func testThatItHandlesMoreThanTwoComponents() {
    var (firstName, lastName) = NameComponentsSplitter.split(fullName: "John Clark Smith")
    XCTAssertEqual(firstName, "John Clark")
    XCTAssertEqual(lastName, "Smith")

    (firstName, lastName) = NameComponentsSplitter.split(fullName: "John Clark Jr. Smith")
    XCTAssertEqual(firstName, "John Clark Jr.")
    XCTAssertEqual(lastName, "Smith")
}

func testThatItHandlesEmptyInput() {
    let (firstName, lastName) = NameComponentsSplitter.split(fullName: "")
    XCTAssertEqual(firstName, nil)
    XCTAssertEqual(lastName, nil)
}

The short answer is that you can't do it using JavaScript alone. You'd need a server-side handler to connect with the SMTP server to actually send the mail. There are many simple mail scripts online, such as this one for PHP:

Simple PHP mail script

Using a script like that, you'd POST the contents of your web form to the script, using a function like this:

jQuery.post

And then the script would take those values, plus a username and password for the mail server, and connect to the server to send the mail.

You can use

my_array=( $(<command>) )

to store the output of command <command> into the array my_array.

You can access the length of that array using

my_array_length=${#my_array[@]}

Now the length is stored in my_array_length.

You could google on "tuple unpacking". This can be used in various places in Python. The simplest is in assignment

>>> x = (1,2)
>>> a, b = x
>>> a
1
>>> b
2

In a for loop it works similarly. If each element of the iterable is a tuple, then you can specify two variables and each element in the loop will be unpacked to the two.

>>> x = [(1,2), (3,4), (5,6)]
>>> for item in x:
...     print "A tuple", item
A tuple (1, 2)
A tuple (3, 4)
A tuple (5, 6)
>>> for a, b in x:
...     print "First", a, "then", b
First 1 then 2
First 3 then 4
First 5 then 6

The enumerate function creates an iterable of tuples, so it can be used this way.
