If you want square borders and still want the little expander arrow, I recommend this:

select.squarecorners{
     border: 0;
     outline: 1px solid #CCC;
     background-color: white;
}

The for loop iterates over the elements of the array, not its indexes. Suppose you have a list ar = [2, 4, 6]:

When you iterate over it with for i in ar: the values of i will be 2, 4 and 6. So, when you try to access ar[i] for the first value, it might work (as the last position of the list is 2, a[2] equals 6), but not for the latter values, as a[4] does not exist.

If you intend to use indexes anyhow, try using for index, value in enumerate(ar):, then theSum = theSum + ar[index] should work just fine.

I fixed the issue by changing the code to

@Basic(optional = false)
@Column(name = "LastTouched", insertable = false, updatable = false)
@Temporal(TemporalType.TIMESTAMP)
private Date lastTouched;

So the timestamp column is ignored when generating SQL inserts. Not sure if this is the best way to go about this. Feedback is welcome.

I also had the same problem, I searched for the answers many places. I got many similar answers to change the number of process/service handlers. But I thought, what if I forgot to reset it back?

Then I tried using Thread.sleep() method after each of my connection.close();.

I don't know how, but it's working at least for me.

If any one wants to try it out and figure out how it's working then please go ahead. I would also like to know it as I am a beginner in programming world.

First of all let's define where we have to use transaction?

I think correct answer is - when we need to make sure that sequence of actions will be finished together as one atomic operation or no changes will be made even if one of the actions fails.

It is well known practice to put business logic into services. So service methods may contain different actions which must be performed as a single logical unit of work. If so - then such method must be marked as Transactional. Of course, not every method requires such limitation, so you don't need to mark whole service as transactional.

And even more - don't forget to take into account that @Transactional obviously, may reduce method performance. In order to see whole picture you have to know transaction isolation levels. Knowing that might help you avoid using @Transactional where it's not necessarily needed.

For me, the problem was about Maven not able to find proper configurations, since these items were specified in parent pom.

Changing File -> Settings -> Build, Excecution, Deployment -> Maven -> User Settings file to point to my custom settings with proper repositories fixed the problem that was otherwise hiding.

Found out about the problem through Help -> Show log in explorer -> clicking the log file, when previously only got the error in the title and "java.lang.NullPointerException" in the console.

EDIT

As of today with flexbox, you could

body {
  display:flex; flex-direction:column; justify-content:center;
  min-height:100vh;
}

html, body {height:100%;}
html {display:table; width:100%;}

Make selector:

 <?xml version="1.0" encoding="utf-8"?>
<selector xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@color/Green_10" android:state_activated="true" />
    <item android:drawable="@color/Transparent" />
</selector>

Set it as background at your list item layout

   <?xml version="1.0" encoding="utf-8"?>
    <androidx.constraintlayout.widget.ConstraintLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:app="http://schemas.android.com/apk/res-auto"
        xmlns:tools="http://schemas.android.com/tools"
        android:background="@drawable/selector_attentions_list_item"
        android:layout_width="match_parent"
        android:layout_height="64dp">

In your adapter add OnClickListener to the view (onBind method)

 @Suppress("UNCHECKED_CAST")
    inner class ViewHolder(itemView: View) : RecyclerView.ViewHolder(itemView) {

        fun bindItems(item: T) {
            initItemView(itemView, item)
            itemView.tag = item
            if (isClickable) {
                itemView.setOnClickListener(onClickListener)
            }
        }
    }

In the onClick event activate the view:

 fun onItemClicked(view: View){
        view.isActivated = true
    }

Also look at log4net, which makes logging to 1 or more event stores — whether it's the console, the Windows event log, a text file, a network pipe, a SQL database, etc. — pretty trivial. You can even filter stuff in its configuration, for instance, so that only log records of a particular severity (say ERROR or FATAL) from a single component or assembly are directed to a particular event store.

You need to use bodyParser() if you want the form data to be available in req.body. body-parser parses your request and converts it into a format from which you can easily extract relevant information that you may need.

For example, let’s say you have a sign-up form at your frontend. You are filling it, and requesting server to save the details somewhere.

Extracting username and password from your request goes as simple as below if you use body-parser.

…………………………………………………….

var loginDetails = {

username : request.body.username,

password : request.body.password

};

I think the better answer for this questions is

array_diff() 

because it Compares array against one or more other arrays and returns the values in array that are not present in any of the other arrays.

Whereas

array_intersect() returns an array containing all the values of array that are present in all the arguments. Note that keys are preserved.

I faced similar issues with POST Request where GET Request was working fine on my backend which i am passing my variables etc. The problem lies in there that the backend does a lot of redirects, which didnt work with fopen or the php header methods.

So the only way i got it working was to put a hidden form and push over the values with a POST submit when the page is loaded.

echo
'<body onload="document.redirectform.submit()">   
    <form method="POST" action="http://someurl/todo.php" name="redirectform" style="display:none">
    <input name="var1" value=' . $var1. '>
    <input name="var2" value=' . $var2. '>
    <input name="var3" value=' . $var3. '>
    </form>
</body>';

I did it with these values within a LinearLayout:

Scale type: fitStart
Layout gravity: fill_horizontal
Layout height: wrap_content
Layout weight: 1
Layout width: fill_parent

I suspect that result1 has some characters at the end of it that you can't see in the debugger that follow the closing } character. What's the length of result1 versus result2? I'll note that result2 as you've quoted it has 169 characters.

GSON throws that particular error when there's extra characters after the end of the object that aren't whitespace, and it defines whitespace very narrowly (as the JSON spec does) - only \t, \n, \r, and space count as whitespace. In particular, note that trailing NUL (\0) characters do not count as whitespace and will cause this error.

If you can't easily figure out what's causing the extra characters at the end and eliminate them, another option is to tell GSON to parse in lenient mode:

Gson gson = new Gson();
JsonReader reader = new JsonReader(new StringReader(result1));
reader.setLenient(true);
Userinfo userinfo1 = gson.fromJson(reader, Userinfo.class);

I'm not familiar with the async keyword (is this specific to Silverlight or a new feature in the beta version of Visual Studio?), but I think I can give you an idea of why you can't do this.

If I do:

var o = new MyObject();
MessageBox(o.SomeProperty.ToString());

o may not be done initializing before the next line of code runs. An instantiation of your object cannot be assigned until your constructor is completed, and making the constructor asynchronous wouldn't change that so what would be the point? However, you could call an asynchronous method from your constructor and then your constructor could complete and you would get your instantiation while the async method is still doing whatever it needs to do to setup your object.

If you're using Maven 3, one option to work around this problem is to use the versions plugin http://www.mojohaus.org/versions-maven-plugin/

Specifically the commands,

mvn versions:set -DnewVersion=2.0-RELEASE
mvn versions:commit

This will update the parent and child poms to 2.0-RELEASE. You can run this as a build step before.

Unlike the release plugin, it doesn't try to talk to your source control

This worked for me.

sudo apt-get install php-curl

You can use assign (doc) to change the value of perf.a1:

> assign(paste("perf.a", "1", sep=""),5)
> perf.a1
[1] 5

Still the intermediate variable is needed, (see var val=) else the cursor behaves strange, we need it at the end.

<body onload="document.getElementById('userinput').focus();">
<form>
<input id="userinput" onfocus="var val=this.value; this.value=''; this.value= val;"
         class=large type="text" size="10" maxlength="50" value="beans" name="myinput">
</form>
</body>

When sending data to a web server, the data has to be a string (here). You can convert a JavaScript object into a string with JSON.stringify(). Here is a working example:

var fs = require('fs');

var originalNote = {
  title: 'Meeting',
  description: 'Meeting John Doe at 10:30 am'
};

var originalNoteString = JSON.stringify(originalNote);

fs.writeFileSync('notes.json', originalNoteString);

var noteString = fs.readFileSync('notes.json');

var note = JSON.parse(noteString);

console.log(`TITLE: ${note.title} DESCRIPTION: ${note.description}`);

Hope it could help.

Use a static AutoResetEvent in your spawned threads to call back to the main thread using the Set() method. This guy has a fairly good demo in SO on how to use it.

AutoResetEvent clarification

If you're attaching a database, take a look at the "Databases to attach" grid, and specifically in the Owner column after you've specified your .mdf file. Note the account and give Full Permissions to it for both mdf and ldf files.

It also important to make sure that the web server sends the file with Content-Disposition = inline. this might not be the case if you are reading the file yourself and send it's content to the browser:

in php it will look like this...

...headers...
header("Content-Disposition: inline; filename=doc.pdf");
...headers...

readfile('localfilepath.pdf')

Your response is almost certainly a string. You need to make sure it gets converted to a number:

document.getElementById("points").value= new Number(request.responseText);

You might take a closer look at your responseText. It sound like you are getting a string that contains quotes. If you are getting JSON data via AJAX, you might have more consistent results running it through JSON.parse().

document.getElementById("points").value= new Number(JSON.parse(request.responseText));

Here's a rather simple solution:

In the controller we return our errors like this:

if (!ModelState.IsValid)
        {
            return Json(new { success = false, errors = ModelState.Values.SelectMany(x => x.Errors).Select(x => x.ErrorMessage).ToList() }, JsonRequestBehavior.AllowGet);
        }

Here's some of the client script:

function displayValidationErrors(errors)
{
    var $ul = $('div.validation-summary-valid.text-danger > ul');

    $ul.empty();
    $.each(errors, function (idx, errorMessage) {
        $ul.append('<li>' + errorMessage + '</li>');
    });
}

That's how we handle it via ajax:

$.ajax({
    cache: false,
    async: true,
    type: "POST",
    url: form.attr('action'),
    data: form.serialize(),
    success: function (data) {
        var isSuccessful = (data['success']);

        if (isSuccessful) {
            $('#partial-container-steps').html(data['view']);
            initializePage();
        }
        else {
            var errors = data['errors'];

            displayValidationErrors(errors);
        }
    }
});

Also, I render partial views via ajax in the following way:

var view = this.RenderRazorViewToString(partialUrl, viewModel);
        return Json(new { success = true, view }, JsonRequestBehavior.AllowGet);

RenderRazorViewToString method:

public string RenderRazorViewToString(string viewName, object model)
    {
        ViewData.Model = model;
        using (var sw = new StringWriter())
        {
            var viewResult = ViewEngines.Engines.FindPartialView(ControllerContext,
                                                                     viewName);
            var viewContext = new ViewContext(ControllerContext, viewResult.View,
                                         ViewData, TempData, sw);
            viewResult.View.Render(viewContext, sw);
            viewResult.ViewEngine.ReleaseView(ControllerContext, viewResult.View);
            return sw.GetStringBuilder().ToString();
        }
    }

Make your audioSounds and minTime variables as static variables, as you are using them in a static method (playSound).

Marking a method as static prevents the usage of non-static (instance) members in that method.

You can not call network on the main thread or UI thread. On Android if you want to call network there are two options -

1. Call asynctask, which will run one background thread to handle the network operation.
2. You can create your own runnable thread to handle the network operation.

Personally I prefer asynctask. For further information you can refer this link.

I've tried lots of different answers in different forums. I guess it depends on the machine your developing. But I haved used the statement

ax.lines = []

and works perfectly. I don't use cla() cause it deletes all the definitions I've made to the plot

Ex.

pylab.setp(_self.ax.get_yticklabels(), fontsize=8)

but I've tried deleting the lines many times. Also using the weakref library to check the reference to that line while I was deleting but nothing worked for me.

Hope this works for someone else =D

This is precisely what the member function std::vector::insert is for

std::vector<int> AB = A;
AB.insert(AB.end(), B.begin(), B.end());

Only want to clone the structure of table:

CREATE TABLE foo SELECT * FROM bar WHERE 1 = 2;

Also wants to copy the data:

CREATE TABLE foo as SELECT * FROM bar;

this method also encounter a deprecate warning:

org.junit.Assert.assertEquals(float expected,float actual) //deprecated

It is because currently junit prefer a third parameter rather than just two float variables input.

The third parameter is delta:

public static void assertEquals(double expected,double actual,double delta) //replacement

this is mostly used to deal with inaccurate Floating point calculations

for more information, please refer this problem: Meaning of epsilon argument of assertEquals for double values

Issue can be solved by adding CRT of msvcrtd.lib in the linker library. Because cryptlib.lib used CRT version of debug.

You can use \n for new line and \t for tabs. Also, extra spaces/tabs are just copied the way you write them in Strings.xml so just give a couple of spaces where ever you want them.

A better way to reach this would probably be using padding/margin in your view xml and splitting up your long text in different strings in your string.xml

Instead of using a ugly log file, you can also activate Fusion log via ETW/xperf by turning on the DotnetRuntime Private provider (Microsoft-Windows-DotNETRuntimePrivate) with GUID 763FD754-7086-4DFE-95EB-C01A46FAF4CA and the FusionKeyword keyword (0x4) on.

When you now open the ETL file in PerfView and look under the Events table, you can find the Fusion data:

Before using multidimensional arrays in Swift, consider their impact on performance. In my tests, the flattened array performed almost 2x better than the 2D version:

var table = [Int](repeating: 0, count: size * size)
let array = [Int](1...size)
for row in 0..<size {
    for column in 0..<size {
        let val = array[row] * array[column]
        // assign
        table[row * size + column] = val
    }
}

Average execution time for filling up a 50x50 Array: 82.9ms

vs.

var table = [[Int]](repeating: [Int](repeating: 0, count: size), count: size)
let array = [Int](1...size)
for row in 0..<size {
    for column in 0..<size {
        // assign
        table[row][column] = val
    }
}

Average execution time for filling up a 50x50 2D Array: 135ms

Both algorithms are O(n^2), so the difference in execution times is caused by the way we initialize the table.

Finally, the worst you can do is using append() to add new elements. That proved to be the slowest in my tests:

var table = [Int]()    
let array = [Int](1...size)
for row in 0..<size {
    for column in 0..<size {
        table.append(val)
    }
}

Average execution time for filling up a 50x50 Array using append(): 2.59s

Conclusion

Avoid multidimensional arrays and use access by index if execution speed matters. 1D arrays are more performant, but your code might be a bit harder to understand.

You can run the performance tests yourself after downloading the demo project from my GitHub repo: https://github.com/nyisztor/swift-algorithms/tree/master/big-o-src/Big-O.playground

With Entity Framework 6 you can execute something like below

Create Modal Class as

Public class User
{
        public int Id { get; set; }
        public string fname { get; set; }
        public string lname { get; set; }
        public string username { get; set; }
}

Execute Raw DQL SQl command as below:

var userList = datacontext.Database.SqlQuery<User>(@"SELECT u.Id ,fname , lname ,username FROM dbo.Users").ToList<User>();

A more Kotlin & Material Design way using TextInputEditText (this approach is also compatible with EditTextView)...

1.Make the parent view(content view of your activity/fragment) clickable and focusable by adding the following attributes

android:focusable="true"
android:focusableInTouchMode="true"
android:clickable="true"

2.Create an extension for all View (inside a ViewExtension.kt file for example) :

fun View.hideKeyboard(){
    val inputMethodManager = context.getSystemService(Activity.INPUT_METHOD_SERVICE) as InputMethodManager
    inputMethodManager.hideSoftInputFromWindow(this.windowToken, 0)
}

3.Create a BaseTextInputEditText that inherit of TextInputEditText. Implement the method onFocusChanged to hide keyboard when the view is not focused :

class BaseTextInputEditText(context: Context?, attrs: AttributeSet?) : TextInputEditText(context, attrs){
    override fun onFocusChanged(focused: Boolean, direction: Int, previouslyFocusedRect: Rect?) {
        super.onFocusChanged(focused, direction, previouslyFocusedRect)
        if (!focused) this.hideKeyboard()
    }
}

4.Just call your brand new custom view in your XML :

<android.support.design.widget.TextInputLayout
        android:id="@+id/textInputLayout"
        ...>

        <com.your_package.BaseTextInputEditText
            android:layout_width="match_parent"
            android:layout_height="wrap_content"
            ... />

    </android.support.design.widget.TextInputLayout> 

That's all. No need to modify your controllers (fragment or activity) to handle this repetitive case.

You can use the jquery highlight effect.

But if you are interested in raw javascript code, take a look at what I got Simply copy paste into an HTML, open the file and click "highlight" - this should highlight the word "fox". Performance wise I think this would do for small text and a single repetition (like you specified)

function highlight(text) {_x000D_
  var inputText = document.getElementById("inputText");_x000D_
  var innerHTML = inputText.innerHTML;_x000D_
  var index = innerHTML.indexOf(text);_x000D_
  if (index >= 0) { _x000D_
   innerHTML = innerHTML.substring(0,index) + "<span class='highlight'>" + innerHTML.substring(index,index+text.length) + "</span>" + innerHTML.substring(index + text.length);_x000D_
   inputText.innerHTML = innerHTML;_x000D_
  }_x000D_
}

.highlight {_x000D_
  background-color: yellow;_x000D_
}

<button onclick="highlight('fox')">Highlight</button>_x000D_
_x000D_
<div id="inputText">_x000D_
  The fox went over the fence_x000D_
</div>

Edits:

Using replace

I see this answer gained some popularity, I thought I might add on it. You can also easily use replace

"the fox jumped over the fence".replace(/fox/,"<span>fox</span>");

Or for multiple occurrences (not relevant for the question, but was asked in comments) you simply add global on the replace regular expression.

"the fox jumped over the other fox".replace(/fox/g,"<span>fox</span>");

Hope this helps to the intrigued commenters.

Replacing the HTML to the entire web-page

to replace the HTML for an entire web-page, you should refer to innerHTML of the document's body.

document.body.innerHTML

Use this code:

var element = document.createElement("link");
element.setAttribute("rel", "stylesheet");
element.setAttribute("type", "text/css");
element.setAttribute("href", "external.css");
document.getElementsByTagName("head")[0].appendChild(element);

delete[] monsters;

Is incorrect because monsters isn't a pointer to a dynamically allocated array, it is an array of pointers. As a class member it will be destroyed automatically when the class instance is destroyed.

Your other implementation is the correct one as the pointers in the array do point to dynamically allocated Monster objects.

Note that with your current memory allocation strategy you probably want to declare your own copy constructor and copy-assignment operator so that unintentional copying doesn't cause double deletes. (If you you want to prevent copying you could declare them as private and not actually implement them.)

Not answering your question specifically, but isn't that something that should be handled by the presentation layer of your application. Doing it the way you describe creates extra processing on the database end as well as adding extra network traffic (assuming the database exists on a different machine than the application), for something that could be easily computed on the application side, with more rich date processing libraries, as well as being more language agnostic, especially in the case of your first example which contains the abbreviated month name. Anyway the answers others give you should point you in the right direction if you still decide to go this route.

Just add autofocus in first input or textarea.

<input type="text" name="name" id="xax" autofocus="autofocus" />

The above addMethod by Lod Lawson is not completely correct. It's $.validator and not $.validate and the validator method name cb_selectone requires quotes. Here is a corrected version that I tested:

$.validator.addMethod('cb_selectone', function(value,element){
    if(element.length>0){
        for(var i=0;i<element.length;i++){
            if($(element[i]).val('checked')) return true;
        }
        return false;
    }
    return false;
}, 'Please select at least one option');

    [data-value] {
  /* Attribute exists */
}

[data-value="foo"] {
  /* Attribute has this exact value */
}

[data-value*="foo"] {
  /* Attribute value contains this value somewhere in it */
}

[data-value~="foo"] {
  /* Attribute has this value in a space-separated list somewhere */
}

[data-value^="foo"] {
  /* Attribute value starts with this */
}

[data-value|="foo"] {
  /* Attribute value starts with this in a dash-separated list */
}

[data-value$="foo"] {
  /* Attribute value ends with this */
}

Ernesto is right. According to the link he posted [1]:

Updated Client JVM heap configuration

In the Client JVM...

• The default maximum heap size is half of the physical memory up to a physical memory size of 192 megabytes and otherwise one fourth of the physical memory up to a physical memory size of 1 gigabyte.

  For example, if your machine has 128 megabytes of physical memory, then the maximum heap size is 64 megabytes, and greater than or equal to 1 gigabyte of physical memory results in a maximum heap size of 256 megabytes.

• The maximum heap size is not actually used by the JVM unless your program creates enough objects to require it. A much smaller amount, termed the initial heap size, is allocated during JVM initialization. ...

• ...
• Server JVM heap configuration ergonomics are now the same as the Client, except that the default maximum heap size for 32-bit JVMs is 1 gigabyte, corresponding to a physical memory size of 4 gigabytes, and for 64-bit JVMs is 32 gigabytes, corresponding to a physical memory size of 128 gigabytes.

If you mean "how can I get a reference to all markers on a given map" - then I think the answer is "Sorry, you have to do it yourself". I don't think there is any handy "maps.getMarkers()" type function: you have to keep your own references as the points are created:

var allMarkers = [];
....
// Create some markers
for(var i = 0; i < 10; i++) {
    var marker = new google.maps.Marker({...});
    allMarkers.push(marker);
}
...

Then you can loop over the allMarkers array to and do whatever you need to do.

Project Properties -> Compile -> Target CPU -> Any CPU And uncheck Prefer 32 bit

Adding a FileUpload control from the code behind should work just fine, where the HasFile property should be available (for instance in your Click event).

If the properties don't appear to be available (either as a compiler error or via intellisense), you probably are referencing a different variable than you think you are.

Get the value for an array of associative arrays's property when the property name is an integer:

Starting with an Associative Array where the property names are integers:

var categories = [
    {"1":"Category 1"},
    {"2":"Category 2"},
    {"3":"Category 3"},
    {"4":"Category 4"}
];

Push items to the array:

categories.push({"2300": "Category 2300"});
categories.push({"2301": "Category 2301"});

Loop through array and do something with the property value.

for (var i = 0; i < categories.length; i++) {
    for (var categoryid in categories[i]) {
        var category = categories[i][categoryid];
        // log progress to the console
        console.log(categoryid + " : " + category);
        //  ... do something
    }
}

Console output should look like this:

1 : Category 1
2 : Category 2
3 : Category 3
4 : Category 4
2300 : Category 2300
2301 : Category 2301

As you can see, you can get around the associative array limitation and have a property name be an integer.

NOTE: The associative array in my example is the json you would have if you serialized a Dictionary[] object.

this was someone else's answer in the comments...but it should be a real answer:

$("#SomeValue").removeAttr("data-val-required")

tested on MVC 6 with a field having the [Required] attribute

answer stolen from https://stackoverflow.com/users/73382/rob above

If it's really important that you have the correct date and time; it's best to have a service on your server (which you of course have running in UTC) that returns the time. You can then create a new Date on the client and compare the values and if necessary adjust all dates with the offset from the server time.

Why do this? I've had bug reports that was hard to reproduce because I could not find the error messages in the server log, until I noticed that the bug report was mailed two days after I'd received it. You can probably trust the browser to correctly handle time-zone conversion when being sent a UTC timestamp, but you obviously cannot trust the users to have their system clock correctly set. (If the users have their timezone incorrectly set too, there is not really any solution; other than printing the current server time in "local" time)

You can't solve it. Simply answer1.sum()==0, and you can't perform a division by zero.

This happens because answer1 is the exponential of 2 very large, negative numbers, so that the result is rounded to zero.

nan is returned in this case because of the division by zero.

Now to solve your problem you could:

• go for a library for high-precision mathematics, like mpmath. But that's less fun.
• as an alternative to a bigger weapon, do some math manipulation, as detailed below.
• go for a tailored scipy/numpy function that does exactly what you want! Check out @Warren Weckesser answer.

Here I explain how to do some math manipulation that helps on this problem. We have that for the numerator:

exp(-x)+exp(-y) = exp(log(exp(-x)+exp(-y)))
                = exp(log(exp(-x)*[1+exp(-y+x)]))
                = exp(log(exp(-x) + log(1+exp(-y+x)))
                = exp(-x + log(1+exp(-y+x)))

where above x=3* 1089 and y=3* 1093. Now, the argument of this exponential is

-x + log(1+exp(-y+x)) = -x + 6.1441934777474324e-06

For the denominator you could proceed similarly but obtain that log(1+exp(-z+k)) is already rounded to 0, so that the argument of the exponential function at the denominator is simply rounded to -z=-3000. You then have that your result is

exp(-x + log(1+exp(-y+x)))/exp(-z) = exp(-x+z+log(1+exp(-y+x)) 
                                   = exp(-266.99999385580668)

which is already extremely close to the result that you would get if you were to keep only the 2 leading terms (i.e. the first number 1089 in the numerator and the first number 1000 at the denominator):

exp(3*(1089-1000))=exp(-267)

For the sake of it, let's see how close we are from the solution of Wolfram alpha (link):

Log[(exp[-3*1089]+exp[-3*1093])/([exp[-3*1000]+exp[-3*4443])] -> -266.999993855806522267194565420933791813296828742310997510523

The difference between this number and the exponent above is +1.7053025658242404e-13, so the approximation we made at the denominator was fine.

The final result is

'exp(-266.99999385580668) = 1.1050349147204485e-116

From wolfram alpha is (link)

1.105034914720621496.. × 10^-116 # Wolfram alpha.

and again, it is safe to use numpy here too.

If your list of words is of substantial length, and you need to do this test many times, it may be worth converting the list to a set and using set intersection to test (with the added benefit that you wil get the actual words that are in both lists):

>>> long_word_list = 'some one long two phrase three about above along after against'
>>> long_word_set = set(long_word_list.split())
>>> set('word along river'.split()) & long_word_set
set(['along'])

//book[title[@lang='it']]

is actually equivalent to

 //book[title/@lang = 'it']

I tried it using vtd-xml, both expressions spit out the same result... what xpath processing engine did you use? I guess it has conformance issue Below is the code

import com.ximpleware.*;
public class test1 {
  public static void main(String[] s) throws Exception{
      VTDGen vg = new VTDGen();
      if (vg.parseFile("c:/books.xml", true)){
          VTDNav vn = vg.getNav();
          AutoPilot ap = new AutoPilot(vn);
          ap.selectXPath("//book[title[@lang='it']]");
                  //ap.selectXPath("//book[title/@lang='it']");

          int i;
          while((i=ap.evalXPath())!=-1){
              System.out.println("index ==>"+i);
          }
          /*if (vn.endsWith(i, "< test")){
             System.out.println(" good ");  
          }else
              System.out.println(" bad ");*/

      }
  }
}

It can also be done using a single line with while loops and if like this:

if (blah)
    doThis();

It also works with while loops.

Error: java.lang.NoSuchMethodError: javax.persistence.JoinTable.indexes()[Ljavax/persistence/Index;

The only thing that solved my problem was removing the following dependency in pom.xml: <dependency> <groupId>org.hibernate.javax.persistence</groupId> <artifactId>hibernate-jpa-2.1-api</artifactId> <version>1.0.0.Final</version> </dependency>

And replace it for:

<dependency>
  <groupId>javax.persistence</groupId>
  <artifactId>persistence-api</artifactId>
  <version>1.0.2</version>
</dependency>

Hope it helps someone.

Use Query.setParameterList(), Javadoc here.

There are four variants to pick from.

SELECT * 
FROM information_schema.columns 
WHERE column_name = 'My_Column'

You must set your current database name with USE [db_name] before this query.

In C the type of character literals are int and char in C++. This is in C++ required to support function overloading. See this example:

void foo(char c)
{
    puts("char");
}
void foo(int i)
{
    puts("int");
}
int main()
{
    foo('i');
    return 0;
}

Output:

char

You could create triggers to solve this. Here is a tutorial to do so (archived link).

Setting constraints and rules in the database is better than writing special code to handle the same task since it will prevent another developer from writing a different query that bypasses all of the special code and could leave your database with poor data integrity.

For a long time I was copying info to another table using a script since MySQL didn’t support triggers at the time. I have now found this trigger to be more effective at keeping track of everything.

This trigger will copy an old value to a history table if it is changed when someone edits a row. Editor ID and last mod are stored in the original table every time someone edits that row; the time corresponds to when it was changed to its current form.

DROP TRIGGER IF EXISTS history_trigger $$

Another solution would be to keep an Revision field and update this field on save. You could decide that the max is the newest revision, or that 0 is the most recent row. That's up to you.

I had the same error and nothing of previous have helped, so I tried to follow original documentation of Open Graph Protocol and I added prefix attribute to my html tag and everything became awesome.

<html prefix="og: http://ogp.me/ns#">

I was having the same issue, after i remove the repeat 0 0 part, it solved my problem.

A unique constraint is also an index.

First use SHOW INDEX FROM tbl_name to find out the name of the index. The name of the index is stored in the column called key_name in the results of that query.

Then you can use DROP INDEX:

DROP INDEX index_name ON tbl_name

or the ALTER TABLE syntax:

ALTER TABLE tbl_name DROP INDEX index_name

Simplest Answer is "No Direct method of getting it because there is no pre-compiler" But you can do it by yourself. Use classes and then define variables as final so that it can be assumed as constant throughout the program
Don't forget to use final and variable as public or protected not private otherwise you won't be able to access it from outside that class

This question is quite old, but I have made it that way (in TYPO3).

Firstly, I have made a own accessible css-class which I can choose on every content element manually.

Then, I have made a outer three column element with 11 columns (1 - 9 - 1), finally, I have modified the column width of the first and third column with CSS to 12.499999995%.

If you have NVM you can just:

nvm install 0.10

If you don't, you can find NVM and instructions here: https://www.npmjs.com/package/nvm

If you want for some reason to convert your file to base-64 string. Like if you want to pass it via internet, etc... you can do this

Byte[] bytes = File.ReadAllBytes("path");
String file = Convert.ToBase64String(bytes);

And correspondingly, read back to file:

Byte[] bytes = Convert.FromBase64String(b64Str);
File.WriteAllBytes(path, bytes);

Use MM for months. mm is for minutes.

DateTime.Now.ToString("dd/MM/yyyy");

You probably run this code at the begining an hour like (00:00, 05.00, 18.00) and mm gives minutes (00) to your datetime.

From Custom Date and Time Format Strings

"mm" --> The minute, from 00 through 59.

"MM" --> The month, from 01 through 12.

Here is a DEMO. (Which the month part of first line depends on which time do you run this code ;) )

i do nothing, just add this tag in web.config, its working this issue come up one of the following points

1. Use Web Api in the same project using MVC or asp.net forms

2. Use RouteConfig and WebApiConfig in Global.asax as GlobalConfiguration.Configure(WebApiConfig.Register); RouteConfig.RegisterRoutes(RouteTable.Routes);

3. Use RouteConfig for 2 purposes, asp.net forms using with friendlyurl and mvc routing for MVC routing

we just use this tag in web.config, it will work.

<system.webServer>
<modules runAllManagedModulesForAllRequests="true">
   .........................

Sometimes you will need to go to less than a cent and there are international currencies that use very large demoniations. For example, you might charge your customers 0.088 cents per transaction. In my Oracle database the columns are defined as NUMBER(20,4)

I found that this happens because: http://support.microsoft.com/kb/913399

SQL Server only releases all the pages that a heap table uses when the following conditions are true: A deletion on this table occurs. A table-level lock is being held. Note A heap table is any table that is not associated with a clustered index.

If pages are not deallocated, other objects in the database cannot reuse the pages.

However, when you enable a row versioning-based isolation level in a SQL Server 2005 database, pages cannot be released even if a table-level lock is being held.

Microsoft's solution: http://support.microsoft.com/kb/913399

To work around this problem, use one of the following methods: Include a TABLOCK hint in the DELETE statement if a row versioning-based isolation level is not enabled. For example, use a statement that is similar to the following:

DELETE FROM TableName WITH (TABLOCK)

Note represents the name of the table. Use the TRUNCATE TABLE statement if you want to delete all the records in the table. For example, use a statement that is similar to the following:

TRUNCATE TABLE TableName

Create a clustered index on a column of the table. For more information about how to create a clustered index on a table, see the "Creating a Clustered Index" topic in SQL

You'll notice at the bottom of the link that it is NOT noted that it applies to SQL Server 2008 but I think it does

In addition to Trufa's comment, Unicode explicitly isn't UTF-16. When they were first looking into Unicode, it was speculated that a 16-bit integer might be enough to store any code, but in practice that turned out not to be the case. However, UTF-16 is another valid encoding of Unicode - alongside the 8-bit and 32-bit variants - and I believe is the encoding that Microsoft use in memory at runtime on the NT-derived operating systems.

May be below is better.

JSONObject jsonObject=null;
    try {
        jsonObject=new JSONObject();
        jsonObject.put("phonetype","N95");
        jsonObject.put("cat","wp");
        String jsonStr=jsonObject.toString();
    } catch (JSONException e) {
        e.printStackTrace();
    }

There's nothing you can do about it i'm afraid as you won't be able to view it in a readable format, it's pretty much intentional and it'll show the interpreted machine code, there would be no formatting or comments as you normally get in .cs/.c files.

It's pretty much a hit and miss scenario.

Someone has already asked about it on another website

pgBadger is another option - also listed here: https://github.com/dhamaniasad/awesome-postgres#utilities

Requires some additional setup in advance to capture the necessary data in the postgres logs though, see the official website.

You can also use wget to »untar it inline«. Simply specify stdout as the output file (-O -):

wget --no-check-certificate https://github.com/pinard/Pymacs/tarball/v0.24-beta2 -O - | tar xz

json_decode($json, true); 
// the second param being true will return associative array. This one is easy.

Here is my answer to a similar question:

I think (not yet entirely sure) that this is because InvokeRequired will always return false if the control has not yet been loaded/shown. I have done a workaround which seems to work for the moment, which is to simple reference the handle of the associated control in its creator, like so:

var x = this.Handle; 

(See http://ikriv.com/en/prog/info/dotnet/MysteriousHang.html)

Why did it take a lot of valgrind investigation to find this out! Just prove it to yourself with some simple code e.g.

std::vector<std::string> vec;

{
      std::string obj("hello world");
      vec.push_pack(obj);
}

std::cout << vec[0] << std::endl;  

If "hello world" is printed, the object must have been copied

For me, I had changes already in place and I wanted the latest from the base branch. I was unable to do rebase, and cherry-pick would have taken forever, so I did the following:

git fetch origin <base branch name>  
git merge FETCH_HEAD

so in this case:

git fetch origin master  
git merge FETCH_HEAD

FOR /r %%X IN (*) DO (ECHO %%X & DEL %%X)

I have encountered the same problem and found out the solution.

You may look within the first server response and see if the server sent you a cookie.

To check if the server sent you a cookie, you can use HttpURLConnection#getHeaderFields() and look for headers named "Set-Cookie".

If existing, here's the solution for your problem. 100% Working for this case!

+1 if it worked for you.

I know this is a late answer but you could manually change the 7 font declarations in the latest version of Bootstrap:

html {
  font-family: sans-serif;
}

body {
  font-family: sans-serif;
}

pre, code, kbd, samp {
  font-family: monospace;
}

input, button, select, optgroup, textarea {
  font-family: inherit;
}

.tooltip {
  font-family: sans-serif;
}

.popover {
  font-family: sans-serif;
}

.text-monospace {
  font-family: monospace;
}

Good luck.

You should make another XML-spring configuration file in your test resource folder or just copy the old one, it looks fine, but if you're trying to start a web context for testing a micro service, just put the following code as your master test class and inherits from that:

@WebAppConfiguration
@RunWith(SpringRunner.class)
@ContextConfiguration(locations = "classpath*:spring-test-config.xml")
public abstract class AbstractRestTest {
    @Autowired
    private WebApplicationContext wac;
}

char a[2] defines an array of char's. a is a pointer to the memory at the beginning of the array and using == won't actually compare the contents of a with 'ab' because they aren't actually the same types, 'ab' is integer type. Also 'ab' should be "ab" otherwise you'll have problems here too. To compare arrays of char you'd want to use strcmp.

Something that might be illustrative is looking at the typeid of 'ab':

#include <iostream>
#include <typeinfo>
using namespace std;
int main(){
    int some_int =5;
    std::cout << typeid('ab').name() << std::endl;
    std::cout << typeid(some_int).name() << std::endl;
    return 0;
}

on my system this returns:

i
i

showing that 'ab' is actually evaluated as an int.

If you were to do the same thing with a std::string then you would be dealing with a class and std::string has operator == overloaded and will do a comparison check when called this way.

If you wish to compare the input with the string "ab" in an idiomatic c++ way I suggest you do it like so:

#include <iostream>
#include <string>
using namespace std;
int main(){
    string a;
    cout<<"enter ab ";
    cin>>a;
    if(a=="ab"){
         cout<<"correct";
    }
    return 0;
}

This one is due to:

if(a=='ab') , here, a is const char* type (ie : array of char)

'ab' is a constant value,which isn't evaluated as string (because of single quote) but will be evaluated as integer.

Since char is a primitive type inherited from C, no operator == is defined.

the good code should be:

if(strcmp(a,"ab")==0) , then you'll compare a const char* to another const char* using strcmp.

Also, to use your new namespaced class you can also do

var jenine:com.newnamespace.subspace.Jenine = com.newnamespace.subspace.Jenine()

Not my fiddle, but http://jsfiddle.net/maxisam/QrCXh/ shows the difference. The key piece is:

           scope:{
            /* NOTE: Normally I would set my attributes and bindings
            to be the same name but I wanted to delineate between 
            parent and isolated scope. */                
            isolatedAttributeFoo:'@attributeFoo',
            isolatedBindingFoo:'=bindingFoo',
            isolatedExpressionFoo:'&'
        }        

Let me give an example for Including express module with require & import

-require

var express = require('express');

-import

import * as  express from 'express';

So after using any of the above statement we will have a variable called as 'express' with us. Now we can define 'app' variable as,

var app = express(); 

So we use 'require' with 'CommonJS' and 'import' with 'ES6'.

For more info on 'require' & 'import', read through below links.

import - An Update on ES6 Modules in Node.js

I hope help you.

date.setTime( date.getTime() + days * 86400000 );

You can also do it in a three line method:

public static int gcd(int x, int y){
  return (y == 0) ? x : gcd(y, x % y);
}

Here, if y = 0, x is returned. Otherwise, the gcd method is called again, with different parameter values.

EDIT: Updated for jQuery 1.8

jQuery 1.8 will add browser specific transformations. jsFiddle Demo

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: Added code to make it a jQuery function.

For those of you who don't want to read any further, here you go. For more details and examples, read on. jsFiddle Demo.

var rotation = 0;

jQuery.fn.rotate = function(degrees) {
    $(this).css({'-webkit-transform' : 'rotate('+ degrees +'deg)',
                 '-moz-transform' : 'rotate('+ degrees +'deg)',
                 '-ms-transform' : 'rotate('+ degrees +'deg)',
                 'transform' : 'rotate('+ degrees +'deg)'});
    return $(this);
};

$('.rotate').click(function() {
    rotation += 5;
    $(this).rotate(rotation);
});

EDIT: One of the comments on this post mentioned jQuery Multirotation. This plugin for jQuery essentially performs the above function with support for IE8. It may be worth using if you want maximum compatibility or more options. But for minimal overhead, I suggest the above function. It will work IE9+, Chrome, Firefox, Opera, and many others.

Bobby... This is for the people who actually want to do it in the javascript. This may be required for rotating on a javascript callback.

Here is a jsFiddle.

If you would like to rotate at custom intervals, you can use jQuery to manually set the css instead of adding a class. Like this! I have included both jQuery options at the bottom of the answer.

HTML

<div class="rotate">
    <h1>Rotatey text</h1>
</div>

CSS

/* Totally for style */
.rotate {
    background: #F02311;
    color: #FFF;
    width: 200px;
    height: 200px;
    text-align: center;
    font: normal 1em Arial;
    position: relative;
    top: 50px;
    left: 50px;
}

/* The real code */
.rotated {
    -webkit-transform: rotate(45deg);  /* Chrome, Safari 3.1+ */
    -moz-transform: rotate(45deg);  /* Firefox 3.5-15 */
    -ms-transform: rotate(45deg);  /* IE 9 */
    -o-transform: rotate(45deg);  /* Opera 10.50-12.00 */
    transform: rotate(45deg);  /* Firefox 16+, IE 10+, Opera 12.10+ */
}

jQuery

Make sure these are wrapped in $(document).ready

$('.rotate').click(function() {
    $(this).toggleClass('rotated');
});

Custom intervals

var rotation = 0;
$('.rotate').click(function() {
    rotation += 5;
    $(this).css({'-webkit-transform' : 'rotate('+ rotation +'deg)',
                 '-moz-transform' : 'rotate('+ rotation +'deg)',
                 '-ms-transform' : 'rotate('+ rotation +'deg)',
                 'transform' : 'rotate('+ rotation +'deg)'});
});

This is an easy way to present the message if any data is input into the form, and not to show the message if the form is submitted:

$(function () {
    $("input, textarea, select").on("input change", function() {
        window.onbeforeunload = window.onbeforeunload || function (e) {
            return "You have unsaved changes.  Do you want to leave this page and lose your changes?";
        };
    });
    $("form").on("submit", function() {
        window.onbeforeunload = null;
    });
})

Your class doesn't have a __init__(), so by the time it's instantiated, the attribute atoms is not present. You'd have to do C.setdata('something') so C.atoms becomes available.

>>> C = Residues()
>>> C.atoms.append('thing')

Traceback (most recent call last):
  File "<pyshell#84>", line 1, in <module>
    B.atoms.append('thing')
AttributeError: Residues instance has no attribute 'atoms'

>>> C.setdata('something')
>>> C.atoms.append('thing')   # now it works
>>> 

Unlike in languages like Java, where you know at compile time what attributes/member variables an object will have, in Python you can dynamically add attributes at runtime. This also implies instances of the same class can have different attributes.

To ensure you'll always have (unless you mess with it down the line, then it's your own fault) an atoms list you could add a constructor:

def __init__(self):
    self.atoms = []

If you haven't already created the project in Github, do so on that site. If memory serves, they display a page that tells you exactly how to get your existing code into your new repository. At the risk of oversimplification, though, you'd follow Veeti's instructions, then:

git remote add [name to use for remote] [private URI] # associate your local repository to the remote
git push [name of remote] master # push your repository to the remote

You can use following formulas.

For Excel 2007 or later:

=IFERROR(VLOOKUP(D3,List!A:C,3,FALSE),"No Match")

For Excel 2003:

=IF(ISERROR(MATCH(D3,List!A:A, 0)), "No Match", VLOOKUP(D3,List!A:C,3,FALSE))

Note, that

• I'm using List!A:C in VLOOKUP and returns value from column ? 3
• I'm using 4th argument for VLOOKUP equals to FALSE, in that case VLOOKUP will only find an exact match, and the values in the first column of List!A:C do not need to be sorted (opposite to case when you're using TRUE).

For Visual Studio 2017 and its new .csproj format

You can no longer just use Install-Package to point to a local file. (That's likely because the PackageReference element doesn't support file paths; it only allows you to specify the package's Id.)

You first have to tell Visual Studio about the location of your package, and then you can add it to a project. What most people do is go into the NuGet Package Manager and add the local folder as a source (menu Tools ? Options ? NuGet Package Manager ? Package Sources). But that means your dependency's location isn't committed (to version-control) with the rest of your codebase.

Local NuGet packages using a relative path

This will add a package source that only applies to a specific solution, and you can use relative paths.

You need to create a nuget.config file in the same directory as your .sln file. Configure the file with the package source(s) you want. When you next open the solution in Visual Studio 2017, any .nupkg files from those source folders will be available. (You'll see the source(s) listed in the Package Manager, and you'll find the packages on the "Browse" tab when you're managing packages for a project.)

Here's an example nuget.config to get you started:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <packageSources>
        <add key="MyLocalSharedSource" value="..\..\..\some\folder" />
    </packageSources>
</configuration>

Backstory

My use case for this functionality is that I have multiple instances of a single code repository on my machine. There's a shared library within the codebase that's published/deployed as a .nupkg file. This approach allows the various dependent solutions throughout our codebase to use the package within the same repository instance. Also, someone with a fresh install of Visual Studio 2017 can just checkout the code wherever they want, and the dependent solutions will successfully restore and build.

Based on ghostdog74's answer,

dicta = {"a":1,"d":2}
dictb = {"a":5,"d":2}

for value in dicta.values():
    if not value in dictb.values():
        print value

will print differ value of dicta

Given that you have installed Java and preferably a JDK in your system ( answering for Windows because you mentioned it in your question) you should have the keytool utility on your installation's bin folder.

If that's the case, what you can do next is add that bin folder to the PATH environment variable of your Windows installation.

The next time you will open a Windows shell and you'll type keytool you will be able to run the actual utility.

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

There are four main alternatives. Both have their quirks, but Method 4 has many advantages from my view.

./script is a shell script starting by #!/usr/bin/php

Method 1: $argv

./script hello wo8844rld
// $argv[0] = "script", $argv[1] = "hello", $argv[2] = "wo8844rld"

?? Using $argv, the parameter order is critical.

Method 2: getopt()

./script -p7 -e3
// getopt("p::")["p"] = "7", getopt("e::")["e"] = "3"

It's hard to use in conjunction of $argv, because:

?? The parsing of options will end at the first non-option found, anything that follows is discarded.

?? Only 26 parameters as the alphabet.

Method 3: Bash Global variable

P9="xptdr" ./script
// getenv("P9") = "xptdr"
// $_SERVER["P9"] = "xptdr"

Those variables can be used by other programs running in the same shell.

They are blown when the shell is closed, but not when the PHP program is terminated. We can set them permanent in file ~/.bashrc!

Method 4: STDIN pipe and stream_get_contents()

Some piping examples:

Feed a string:

./script <<< "hello wo8844rld"
// stream_get_contents(STDIN) = "hello wo8844rld"

Feed a string using bash echo:

echo "hello wo8844rld" | ./script
// explode(" ",stream_get_contents(STDIN)) ...

Feed a file content:

./script < ~/folder/Special_params.txt
// explode("\n",stream_get_contents(STDIN)) ...

Feed an array of values:

./script <<< '["array entry","lol"]'
// var_dump( json_decode(trim(stream_get_contents(STDIN))) );

Feed JSON content from a file:

echo params.json | ./script
// json_decode(stream_get_contents(STDIN)) ...

It might work similarly to fread() or fgets(), by reading the STDIN.

Bash-Scripting Guide

I have the exact same problem, and here is the solution I make use of now: (Note, this seems ideal to me because it keeps the files closely tied to the SinglePageApplication React app, that loads from Amazon S3. So, it's like storing on S3, and in an application, that knows where it is in S3, relatively speaking.

Steps

3 steps:

1. Make use of file saver in project: npmjs/package/file-saver (npm install file-saver or something)
2. Place the file in your project You say it's in the components folder. Well, chances are if you've got web-pack it's going to try and minify it.(someone please pinpoint what webpack would do with an asset file in components folder), and so I don't think it's what you'd want. So, I suggest to place the asset into the public folder, under a resource or an asset name. Webpack doesn't touch the public folder and index.html and your resources get copied over in production build as is, where you may refer them as shown in next step.
3. Refer to the file in your project Sample code:

   import FileSaver from 'file-saver';
   FileSaver.saveAs(
       process.env.PUBLIC_URL + "/resource/file.anyType",
       "fileNameYouWishCustomerToDownLoadAs.anyType");

On Windows 8.1, IIS 8.5 the solution for me was to register 4.5 from the control panel:

Programs and Features > Turn Windows features on or off > Information Information Services > World Wide Web Services > Application Development Features > Select ASP.NET 4.5

Click OK.

Do you mean like this?

var hello1 = document.getElementById('hello1');
hello1.id = btoa(hello1.id);

To further the example, say you wanted to get all elements with the class 'abc'. We can use querySelectorAll() to accomplish this:

HTML

<div class="abc"></div>
<div class="abc"></div>

JS

var abcElements = document.querySelectorAll('.abc');

// Set their ids
for (var i = 0; i < abcElements.length; i++)
    abcElements[i].id = 'abc-' + i;

This will assign the ID 'abc-<index number>' to each element. So it would come out like this:

<div class="abc" id="abc-0"></div>
<div class="abc" id="abc-1"></div>

To create an element and assign an id we can use document.createElement() and then appendChild().

var div = document.createElement('div');
div.id = 'hello1';

var body = document.querySelector('body');
body.appendChild(div);

Update

You can set the id on your element like this if your script is in your HTML file.

<input id="{{str(product["avt"]["fto"])}}" >
<span>New price :</span>
<span class="assign-me">

<script type="text/javascript">
    var s = document.getElementsByClassName('assign-me')[0];
    s.id = btoa({{str(produit["avt"]["fto"])}});
</script>

Your requirements still aren't 100% clear though.

This is one of the reasons why C++ introduced the new cast style, which includes static_cast and reinterpret_cast

There's two things you can mean by saying conversion from signed to unsigned, you might mean that you wish the unsigned variable to contain the value of the signed variable modulo the maximum value of your unsigned type + 1. That is if your signed char has a value of -128 then CHAR_MAX+1 is added for a value of 128 and if it has a value of -1, then CHAR_MAX+1 is added for a value of 255, this is what is done by static_cast. On the other hand you might mean to interpret the bit value of the memory referenced by some variable to be interpreted as an unsigned byte, regardless of the signed integer representation used on the system, i.e. if it has bit value 0b10000000 it should evaluate to value 128, and 255 for bit value 0b11111111, this is accomplished with reinterpret_cast.

Now, for the two's complement representation this happens to be exactly the same thing, since -128 is represented as 0b10000000 and -1 is represented as 0b11111111 and likewise for all in between. However other computers (usually older architectures) may use different signed representation such as sign-and-magnitude or ones' complement. In ones' complement the 0b10000000 bitvalue would not be -128, but -127, so a static cast to unsigned char would make this 129, while a reinterpret_cast would make this 128. Additionally in ones' complement the 0b11111111 bitvalue would not be -1, but -0, (yes this value exists in ones' complement,) and would be converted to a value of 0 with a static_cast, but a value of 255 with a reinterpret_cast. Note that in the case of ones' complement the unsigned value of 128 can actually not be represented in a signed char, since it ranges from -127 to 127, due to the -0 value.

I have to say that the vast majority of computers will be using two's complement making the whole issue moot for just about anywhere your code will ever run. You will likely only ever see systems with anything other than two's complement in very old architectures, think '60s timeframe.

The syntax boils down to the following:

signed char x = -100;
unsigned char y;

y = (unsigned char)x;                    // C static
y = *(unsigned char*)(&x);               // C reinterpret
y = static_cast<unsigned char>(x);       // C++ static
y = reinterpret_cast<unsigned char&>(x); // C++ reinterpret

To do this in a nice C++ way with arrays:

jbyte memory_buffer[nr_pixels];
unsigned char* pixels = reinterpret_cast<unsigned char*>(memory_buffer);

or the C way:

unsigned char* pixels = (unsigned char*)memory_buffer;

The first parameter to the iterator in forEach is the value and second is the key of the object.

angular.forEach(objectToIterate, function(value, key) {
    /* do something for all key: value pairs */
});

In your example, the outer forEach is actually:

angular.forEach($scope.filters, function(filterObj , filterKey)

Well, for one, I'd get rid of the setters and make Fractions immutable.

You'll probably also want methods to add, subtract, etc., and maybe some way to get the representation in various String formats.

EDIT: I'd probably mark the fields as 'final' to signal my intent but I guess it's not a big deal...

plot(t) is in this case the same as

plot(t[[1]], t[[2]])

As the error message says, x and y differ in length and that is because you plot a list with length 4 against 1:

> length(t)
[1] 4
> length(1)
[1] 1

In your second example you plot a list with elements named x and y, both vectors of length 2, so plot plots these two vectors.

Edit:

If you want to plot lines use

plot(t, type="l")

You can calculate the total (and from that the desired percentage) by using a subquery in the FROM clause:

SELECT Name,
       SUM(Value) AS "SUM(VALUE)",
       SUM(Value) / totals.total AS "% of Total"
FROM   table1,
       (
           SELECT Name,
                  SUM(Value) AS total
           FROM   table1
           GROUP BY Name
       ) AS totals
WHERE  table1.Name = totals.Name
AND    Year BETWEEN 2000 AND 2001
GROUP BY Name;

Note that the subquery does not have the WHERE clause filtering the years.

Your second bit of code starts the first bit of code as a subprocess with piped input and output. It then closes its input and tries to read its output.

The first bit of code tries to read from standard input, but the process that started it closed its standard input, so it immediately reaches an end-of-file, which Python turns into an exception.

If you have fresh installation / update of Xcode, it is possible that your git binary can't be executed (I had mine under /usr/bin/git). To fix this problem just run the Xcode and "Accept" license conditions and try again, it should work.

In my case, I needed to return the enum from a WCF service. I also needed a friendly name, not just the enum.ToString().

Here's my WCF Class.

[DataContract]
public class EnumMember
{
    [DataMember]
    public string Description { get; set; }

    [DataMember]
    public int Value { get; set; }

    public static List<EnumMember> ConvertToList<T>()
    {
        Type type = typeof(T);

        if (!type.IsEnum)
        {
            throw new ArgumentException("T must be of type enumeration.");
        }

        var members = new List<EnumMember>();

        foreach (string item in System.Enum.GetNames(type))
        {
            var enumType = System.Enum.Parse(type, item);

            members.Add(
                new EnumMember() { Description = enumType.GetDescriptionValue(), Value = ((IConvertible)enumType).ToInt32(null) });
        }

        return members;
    }
}

Here's the Extension method that gets the Description from the Enum.

    public static string GetDescriptionValue<T>(this T source)
    {
        FieldInfo fileInfo = source.GetType().GetField(source.ToString());
        DescriptionAttribute[] attributes = (DescriptionAttribute[])fileInfo.GetCustomAttributes(typeof(DescriptionAttribute), false);            

        if (attributes != null && attributes.Length > 0)
        {
            return attributes[0].Description;
        }
        else
        {
            return source.ToString();
        }
    }

Implementation:

return EnumMember.ConvertToList<YourType>();

You can overwrite a CSS class by making it "more specific".

You go up the HTML tree, and specify parent elements:

div.sidebar { ... } is more specific than .sidebar { ... }

You can go all the way up to BODY if you need to:

body .sidebar { ... } will override virtually anything.

See this handy guide: http://css-tricks.com/855-specifics-on-css-specificity/

You don't need the assignment, list.append(x) will always append x to a and therefore there's no need te redefine a.

a = []
for i in range(5):    
    a.append(i)
print(a)

is all you need. This works because lists are mutable.

Also see the docs on data structures.

In the controller:

$scope.entityId = $routeParams.entityId;

In the view:

<input type="hidden" name="entityId" ng-model="entity.entityId" ng-init="entity.entityId = entityId" />

If you don't see the "Browse With..." option stop debugging first. =)

Handlebars partials take a second parameter which becomes the context for the partial:

{{> person this}}

In versions v2.0.0 alpha and later, you can also pass a hash of named parameters:

{{> person headline='Headline'}}

You can see the tests for these scenarios: https://github.com/wycats/handlebars.js/blob/ce74c36118ffed1779889d97e6a2a1028ae61510/spec/qunit_spec.js#L456-L462 https://github.com/wycats/handlebars.js/blob/e290ec24f131f89ddf2c6aeb707a4884d41c3c6d/spec/partials.js#L26-L32

Simply try the following code.

var text= $('#yourslectbox').find(":selected").text();

it returns the text of the selected option.

I'm quite late to the party, but one approach is to use a static inner class to unwrap values:

import com.fasterxml.jackson.annotation.JsonCreator;
import com.fasterxml.jackson.annotation.JsonProperty;
import com.fasterxml.jackson.core.JsonProcessingException;
import com.fasterxml.jackson.databind.ObjectMapper;

class Scratch {
    private final String aString;
    private final String bString;
    private final String cString;
    private final static String jsonString;

    static {
        jsonString = "{\n" +
                "  \"wrap\" : {\n" +
                "    \"A\": \"foo\",\n" +
                "    \"B\": \"bar\",\n" +
                "    \"C\": \"baz\"\n" +
                "  }\n" +
                "}";
    }

    @JsonCreator
    Scratch(@JsonProperty("A") String aString,
            @JsonProperty("B") String bString,
            @JsonProperty("C") String cString) {
        this.aString = aString;
        this.bString = bString;
        this.cString = cString;
    }

    @Override
    public String toString() {
        return "Scratch{" +
                "aString='" + aString + '\'' +
                ", bString='" + bString + '\'' +
                ", cString='" + cString + '\'' +
                '}';
    }

    public static class JsonDeserializer {
        private final Scratch scratch;

        @JsonCreator
        public JsonDeserializer(@JsonProperty("wrap") Scratch scratch) {
            this.scratch = scratch;
        }

        public Scratch getScratch() {
            return scratch;
        }
    }

    public static void main(String[] args) throws JsonProcessingException {
        ObjectMapper objectMapper = new ObjectMapper();
        Scratch scratch = objectMapper.readValue(jsonString, Scratch.JsonDeserializer.class).getScratch();
        System.out.println(scratch.toString());
    }
}

However, it's probably easier to use objectMapper.configure(SerializationConfig.Feature.UNWRAP_ROOT_VALUE, true); in conjunction with @JsonRootName("aName"), as pointed out by pb2q

If an update query executes with values that match the current database record then $stmt->rowCount() will return 0 for no rows were affected. If you have an if( rowCount() == 1 ) to test for success you will think the updated failed when it did not fail but the values were already in the database so nothing change.

$stmt->execute();
if( $stmt ) return "success";

This did not work for me when I tried to update a record with a unique key field that was violated. The query returned success but another query returns the old field value.

The basic formula to reverse positive to negative or negative to positive:

i - (i * 2)

There appear to be two problems.

1. You're using the ^ outside a [] which matches the start of the line
2. You're not using a * or + which means you will only match a single character.

I think you want the following regex @"([^a-zA-Z0-9\s])+"

def prepare_table_row(row):
    lst = [i.text for i in row if i != u'\n']
    return dict(rank = int(lst[0]),
                grade = str(lst[1]),
                channel=str(lst[2])),
                videos = float(lst[3].replace(",", " ")),
                subscribers = float(lst[4].replace(",", "")),
                views = float(lst[5].replace(",", "")))

In the end I made a jQuery plugin that will format the <input type="number" /> appropriately for me. I also noticed on some mobile devices the min and max attributes don't actually prevent you from entering lower or higher numbers than specified, so the plugin will account for that too. Below is the code and an example:

(function($) {_x000D_
  $.fn.currencyInput = function() {_x000D_
    this.each(function() {_x000D_
      var wrapper = $("<div class='currency-input' />");_x000D_
      $(this).wrap(wrapper);_x000D_
      $(this).before("<span class='currency-symbol'>$</span>");_x000D_
      $(this).change(function() {_x000D_
        var min = parseFloat($(this).attr("min"));_x000D_
        var max = parseFloat($(this).attr("max"));_x000D_
        var value = this.valueAsNumber;_x000D_
        if(value < min)_x000D_
          value = min;_x000D_
        else if(value > max)_x000D_
          value = max;_x000D_
        $(this).val(value.toFixed(2)); _x000D_
      });_x000D_
    });_x000D_
  };_x000D_
})(jQuery);_x000D_
_x000D_
$(document).ready(function() {_x000D_
  $('input.currency').currencyInput();_x000D_
});

.currency {_x000D_
  padding-left:12px;_x000D_
}_x000D_
_x000D_
.currency-symbol {_x000D_
  position:absolute;_x000D_
  padding: 2px 5px;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>_x000D_
<input type="number" class="currency" min="0.01" max="2500.00" value="25.00" />

The minimum width that your screen can display is 1 pixel. So its impossible to display less then 1px. 1 pixels can only have 1 color and cannot be split up.

Modifications to sys.path only apply for the life of that Python interpreter. If you want to do it permanently you need to modify the PYTHONPATH environment variable:

PYTHONPATH="/Me/Documents/mydir:$PYTHONPATH"
export PYTHONPATH

Note that PATH is the system path for executables, which is completely separate.

This is a very late answer,but this might help.I went to this link and searched for ojdbc8(I was trying to add jdbc oracle driver) When clicked on the result , a note was displayed like this:

I clicked the link in the note and the correct dependency was mentioned like below

WakeLock doesn't usually cause Reboot problems. There may be some other issues in your coding. WakeLock hogs battery heavily, if not released after usage.

WakeLock is an Inefficient way of keeping the screen on. Instead use the WindowManager to do the magic. The following one line will suffice the WakeLock. The WakeLock Permission is also needed for this to work. Also this code is more efficient than the wakeLock.

getWindow().addFlags(WindowManager.LayoutParams.FLAG_KEEP_SCREEN_ON);

You need not relase the WakeLock Manually. This code will allow the Android System to handle the Lock Automatically. When your application is in the Foreground then WakeLock is held and else android System releases the Lock automatically.

Try this and post your comment...

Using PowerShell, you can use the following

Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Select name

This will show a list off all services which displayname starts with "NATION-".

You can also directly stop or start the services;

Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Stop-Service
Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Start-Service

or simply

Get-Service | Where-Object {$_.displayName.StartsWith("NATION-")} | Restart-Service

Maybe not as clean or efficient as the already posted solutions, but how about the .each() function? E.g:

var mvar = "";
$(".mbox").each(function() {
    console.log($(this).html());
    mvar += $(this).html();
});
console.log(mvar);

Alt + Right Arrow and Alt + Numpad 6 (if Num Lock is disabled) are also possibilities.

I tried this and it worked

<div class="container">_x000D_
 <div class="row justify-content-center">_x000D_
  <div class="form-group col-md-4 col-md-offset-5 align-center ">_x000D_
       <input type="text" name="username" placeholder="Username" >_x000D_
  </div>_x000D_
 </div> _x000D_
</div>

I open the project,.csproj, using a notepad and delete that missing file reference.

That depends on what headers you are sending along with your CSS files. Check your server configuration as you are probably not sending them manually. Do a google search for "http caching" to learn about different caching options you can set. You can force the browser to download a fresh copy of the file everytime it loads it for instance, or you can cache the file for one week...

Use the valueOf method which is automatically created for each Enum.

Verbosity.valueOf("BRIEF") == Verbosity.BRIEF

For arbitrary values start with:

public static Verbosity findByAbbr(String abbr){
    for(Verbosity v : values()){
        if( v.abbr().equals(abbr)){
            return v;
        }
    }
    return null;
}

Only move on later to Map implementation if your profiler tells you to.

I know it's iterating over all the values, but with only 3 enum values it's hardly worth any other effort, in fact unless you have a lot of values I wouldn't bother with a Map it'll be fast enough.

The Northwind example cited by Marc Gravell can be rewritten with the City column selected directly by the group statement:

from cust in ctx.Customers
where cust.CustomerID != ""
group cust.City /*here*/ by cust.Country
into grp
select new
{
        Country = grp.Key,
        Count = grp.Distinct().Count()
};

ES6 / ES2015 provides an API for asking whether a string ends with something, which enables writing a cleaner and more readable function.

const stripTrailingSlash = (str) => {
    return str.endsWith('/') ?
        str.slice(0, -1) :
        str;
};

Found the port esp32 was connected to by -

ls /dev/*

You would get a long list and you can find the port you need

The six types of object reachability states in Java:

1. Strongly reachable objects - GC will not collect (reclaim the memory occupied by) this kind of object. These are reachable via a root node or another strongly reachable object (i.e. via local variables, class variables, instance variables, etc.)
2. Softly reachable objects - GC may attempt to collect this kind of object depending on memory contention. These are reachable from the root via one or more soft reference objects
3. Weakly reachable objects - GC must collect this kind of object. These are reachable from the root via one or more weak reference objects
4. Resurrect-able objects - GC is already in the process of collecting these objects. But they may go back to one of the states - Strong/Soft/Weak by the execution of some finalizer
5. Phantomly reachable object - GC is already in the process of collecting these objects and has determined to not be resurrect-able by any finalizer (if it declares a finalize() method itself, then its finalizer will have been run). These are reachable from the root via one or more phantom reference objects
6. Unreachable object - An object is neither strongly, softly, weakly, nor phantom reachable, and is not resurrectable. These objects are ready for reclamation

Laravel has a built-in method to shuffle the order of the results.

Here is a quote from the documentation:

shuffle()

The shuffle method randomly shuffles the items in the collection:

$collection = collect([1, 2, 3, 4, 5]);

$shuffled = $collection->shuffle();

$shuffled->all();

// [3, 2, 5, 1, 4] - (generated randomly)

You can see the documentation here.

To do this without any headache:

1. Check out what's the current branch in the gitrepo1 with git status, let's say branch "development".
2. Change directory to the newrepo, then git clone the project from repository.
3. Switch branch in newrepo to the previous one: git checkout development.
4. Syncronize newrepo with the older one, gitrepo1 using rsync, excluding .git folder: rsync -azv --exclude '.git' gitrepo1 newrepo/gitrepo1. You don't have to do this with rsync of course, but it does it so smooth.

The benefit of this approach: you are good to continue exactly where you left off: your older branch, unstaged changes, etc.

Another way to do this is to define the functions in a groovy class and parse and add the file to the classpath at runtime:

File sourceFile = new File("path_to_file.groovy");
Class groovyClass = new GroovyClassLoader(getClass().getClassLoader()).parseClass(sourceFile);
GroovyObject myObject = (GroovyObject) groovyClass.newInstance();

<pre lang="xml" >{{xmlString}}</pre>

This worked for me. Thanks to http://www.codeproject.com/Answers/998872/Display-XML-in-HTML-Div#answer1

Use this to lock view controller orientation, tested on IOS 9:

// Lock orientation to landscape right

-(UIInterfaceOrientationMask)supportedInterfaceOrientations {
    return UIInterfaceOrientationMaskLandscapeRight;
}

-(NSUInteger)navigationControllerSupportedInterfaceOrientations:(UINavigationController *)navigationController {
    return UIInterfaceOrientationMaskLandscapeRight;
}

You cannot truncate a table if you don't drop the constraints. A disable also doesn't work. you need to Drop everything. i've made a script that drop all constrainsts and then recreate then.

Be sure to wrap it in a transaction ;)

I know this is quite an old post but I just spent some time trying to make this work in IE8.

It appears that there are some differences in IE8 versions because solutions posted here and in other threads didn't work for me.

Let's say that we have this code:

$('a').on('click', function(event) {
    event.preventDefault ? event.preventDefault() : event.returnValue = false;
});

In my IE8 preventDefault() method exists because of jQuery, but is not working (probably because of the point below), so this will fail.

Even if I set returnValue property directly to false:

$('a').on('click', function(event) {
    event.returnValue = false;
    event.preventDefault();
});

This also won't work, because I just set some property of jQuery custom event object.

Only solution that works for me is to set property returnValue of global variable event like this:

$('a').on('click', function(event) {
    if (window.event) {
        window.event.returnValue = false;
    }
    event.preventDefault();
});

Just to make it easier for someone who will try to convince IE8 to work. I hope that IE8 will die horribly in painful death soon.

UPDATE:

As sv_in points out, you could use event.originalEvent to get original event object and set returnValue property in the original one. But I haven't tested it in my IE8 yet.

I heard a good description (parable) which illustrates ports as different delivery points for a large building, e.g. Post office for letters and small parcels, Goods In for large deliveries / pallets, Doors for people.

Most UNIX-like operating systems have a basename executable for a very similar purpose (and dirname for the path):

pax> a=/tmp/file.txt
pax> b=$(basename $a)
pax> echo $b
file.txt

That unfortunately just gives you the file name, including the extension, so you'd need to find a way to strip that off as well.

So, given you have to do that anyway, you may as well find a method that can strip off the path and the extension.

One way to do that (and this is a bash-only solution, needing no other executables):

pax> a=/tmp/xx/file.tar.gz
pax> xpath=${a%/*} 
pax> xbase=${a##*/}
pax> xfext=${xbase##*.}
pax> xpref=${xbase%.*}
pax> echo;echo path=${xpath};echo pref=${xpref};echo ext=${xfext}

path=/tmp/xx
pref=file.tar
ext=gz

That little snippet sets xpath (the file path), xpref (the file prefix, what you were specifically asking for) and xfext (the file extension).

Looking for this on 2018. Click event on option tag, inside a select tag, is not fired on Chrome.

Use change event, and capture the selected option:

$(document).delegate("select", "change", function() {
    //capture the option
    var $target = $("option:selected",$(this));
});

Be aware that $target may be a collection of objects if the select tag is multiple.

The Problem is with your code formatting,

inorder to use strtotime() You should replace '06/Oct/2011:19:00:02' with 06/10/2011 19:00:02 and date('d/M/Y:H:i:s', $date); with date('d/M/Y H:i:s', $date);. Note the spaces in between.

So the final code looks like this

$s = '06/10/2011 19:00:02';
$date = strtotime($s);
echo date('d/M/Y H:i:s', $date);

My approach, i think coming more from an development than an operations point of view, is:

• Error means that the execution of some task could not be completed; an email couldn't be sent, a page couldn't be rendered, some data couldn't be stored to a database, something like that. Something has definitively gone wrong.
• Warning means that something unexpected happened, but that execution can continue, perhaps in a degraded mode; a configuration file was missing but defaults were used, a price was calculated as negative, so it was clamped to zero, etc. Something is not right, but it hasn't gone properly wrong yet - warnings are often a sign that there will be an error very soon.
• Info means that something normal but significant happened; the system started, the system stopped, the daily inventory update job ran, etc. There shouldn't be a continual torrent of these, otherwise there's just too much to read.
• Debug means that something normal and insignificant happened; a new user came to the site, a page was rendered, an order was taken, a price was updated. This is the stuff excluded from info because there would be too much of it.
• Trace is something i have never actually used.

First of all, to compare the two first you should distinguish queries with subqueries to:

1. a class of subqueries that always have corresponding equivalent query written with joins
2. a class of subqueries that can not be rewritten using joins

For the first class of queries a good RDBMS will see joins and subqueries as equivalent and will produce same query plans.

These days even mysql does that.

Still, sometimes it does not, but this does not mean that joins will always win - I had cases when using subqueries in mysql improved performance. (For example if there is something preventing mysql planner to correctly estimate the cost and if the planner doesn't see the join-variant and subquery-variant as same then subqueries can outperform the joins by forcing a certain path).

Conclusion is that you should test your queries for both join and subquery variants if you want to be sure which one will perform better.

For the second class the comparison makes no sense as those queries can not be rewritten using joins and in these cases subqueries are natural way to do the required tasks and you should not discriminate against them.

Or you could use File.AppendAllLines(string, IEnumerable<string>)

File.AppendAllLines(@"C:\Path\file.txt", new[] { "my text content" });

Put them into a list and use merge with Reduce

Reduce(function(x, y) merge(x, y, all=TRUE), list(df1, df2, df3))
#    id v1 v2 v3
# 1   1  1 NA NA
# 2  10  4 NA NA
# 3   2  3  4 NA
# 4  43  5 NA NA
# 5  73  2 NA NA
# 6  23 NA  2  1
# 7  57 NA  3 NA
# 8  62 NA  5  2
# 9   7 NA  1 NA
# 10 96 NA  6 NA

You can also use this more concise version:

Reduce(function(...) merge(..., all=TRUE), list(df1, df2, df3))

Let i have the following checkboxes

 <input type="checkbox" name="vehicle" value="select All" id="chk_selall">Select ALL<br>
        <input type="checkbox" name="vehicle" value="Bike" id="chk_byk">bike<br>
        <input type="checkbox" name="vehicle" value="Car" id="chk_car">car 
        <input type="checkbox" name="vehicle" value="Bike" id="chk_bus">Bus<br>
        <input type="checkbox" name="vehicle" value="scooty" id="chk_scooty">scooty 

Here is the simple code to select all and diselect all when the selectall check box will click

<script type="text/javascript">
        $(document).ready(function () {
            $("#chk_selall").on("click", function () {

                $("#chk_byk").prop("checked", true); 
                $("#chk_car").prop("checked", true); 
                $("#chk_bus").prop("checked", true); 
                $("#chk_scooty").prop("checked", true); 


            })

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

                if (!$(this).prop("checked"))
                {
                    $("#chk_byk").prop("checked", false);
                    $("#chk_car").prop("checked", false);

@vnr you can retrieve all the sort keys associated with a partition key by just using the query using partion key. No need of scan. The point here is partition key is compulsory in a query . Sort key are used only to get range of data

going off of jan's answer of shallow-copying the object, another clean implementation using map function,

High level of what this solution does: iterate through all the rows and copy the rows as valid js objects.

// function  will be used on every row returned by the query
const objectifyRawPacket = row => ({...row});

// iterate over all items and convert the raw packet row -> js object
const convertedResponse = results.map(objectifyRawPacket);

We leveraged the array map function: it will go over every item in the array, use the item as input to the function, and insert the output of the function into the array you're assigning.

more specifically on the objectifyRawPacket function: each time it's called its seeing the "{ RawDataPacket }" from the source array. These objects act a lot like normal objects - the "..." (spread) operator copies items from the array after the periods - essentially copying the items into the object it's being called in.

The parens around the spread operator on the function are necessary to implicitly return an object from an arrow function.

Password is a reserved word. Bracket that field name to avoid confusing the db engine.

INSERT into Login (Username, [Password])

You can write this in a more compact way:

var now = new Date();
now.setTime(now.getTime() + 1 * 3600 * 1000);
document.cookie = "name=value; expires=" + now.toUTCString() + "; path=/";

And for someone like me, who wasted an hour trying to figure out why the cookie with expiration is not set up (but without expiration can be set up) in Chrome, here is in answer:

For some strange reason Chrome team decided to ignore cookies from local pages. So if you do this on localhost, you will not be able to see your cookie in Chrome. So either upload it on the server or use another browser.

It's OK to run Docker-in-Docker (DinD) and in fact Docker (the company) has an official DinD image for this.

The caveat however is that it requires a privileged container, which depending on your security needs may not be a viable alternative.

The alternative solution of running Docker using sibling containers (aka Docker-out-of-Docker or DooD) does not require a privileged container, but has a few drawbacks that stem from the fact that you are launching the container from within a context that is different from that one in which it's running (i.e., you launch the container from within a container, yet it's running at the host's level, not inside the container).

I wrote a blog describing the pros/cons of DinD vs DooD here.

Having said this, Nestybox (a startup I just founded) is working on a solution that runs true Docker-in-Docker securely (without using privileged containers). You can check it out at www.nestybox.com.

The . operator is for direct member access.

object.Field

The arrow dereferences a pointer so you can access the object/memory it is pointing to

pClass->Field

You can sort a map by value as below, more example here

//Sort a Map by their Value.
Map<Integer, String> random = new HashMap<Integer, String>();

random.put(1,"z");
random.put(6,"k");
random.put(5,"a");
random.put(3,"f");
random.put(9,"c");

Map<Integer, String> sortedMap =
        random.entrySet().stream()
                .sorted(Map.Entry.comparingByValue())
                .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue,
                        (e1, e2) -> e2, LinkedHashMap::new));
System.out.println("Sorted Map: " + Arrays.toString(sortedMap.entrySet().toArray()));

input(char_val, date9.);

You can consider to convert it to word format using input(char_val, worddate.)

You can get a lot in this page http://v8doc.sas.com/sashtml/lrcon/zenid-63.htm

Personally I prefer this way.

Modify the .csproj to add

<ItemGroup>
    <ContentWithTargetPath Include="ConfigFiles\MyFirstConfigFile.txt">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <TargetPath>%(Filename)%(Extension)</TargetPath>
    </ContentWithTargetPath>
</ItemGroup>

or generalizing, if you want to copy all subfolders and files, you could do:

<ItemGroup>
    <ContentWithTargetPath Include="ConfigFiles\**">
      <CopyToOutputDirectory>PreserveNewest</CopyToOutputDirectory>
      <TargetPath>%(RecursiveDir)\%(Filename)%(Extension)</TargetPath>
    </ContentWithTargetPath>
</ItemGroup>

From documentation:

To comply with the SQL standard, IN returns NULL not only if the expression on the left hand side is NULL, but also if no match is found in the list and one of the expressions in the list is NULL.

This is exactly your case.

Both IN and NOT IN return NULL which is not an acceptable condition for WHERE clause.

Rewrite your query as follows:

SELECT  *
FROM    match m
WHERE   NOT EXISTS
        (
        SELECT  1
        FROM    email e
        WHERE   e.id = m.id
        )

A quick fix where nothing else works:

const a.b = 5 // error

const a['b'] = 5 // error if ts-lint rule no-string-literal is enabled

const B = 'b'
const a[B] = 5 // always works

Not good practice but provides a solution without needing to turn off no-string-literal

We need to add host security certificate to php.ini file. For local developement enviroment we can add cacert.pem in your local php.ini.

do phpinfo(); and file your php.ini path open and add uncomment ;curl.capath

curl.capath=path_of_your_cacert.pem

If the properties are for XML or HTML, it's safest to use XML entities. They're uglier to read, but it means that the properties file can be treated as straight ASCII, so nothing will get mangled.

Note that HTML has entities that XML doesn't, so I keep it safe by using straight XML: http://www.w3.org/TR/html4/sgml/entities.html

• Right click the Google Chrome icon and select Properties.
• Copy the value of Target, for example: "C:\Users\zero\AppData\Local\Google\Chrome\Application\chrome.exe".
• Create a shortcut on your Desktop.

• Paste the value into Location of the item, and append --kiosk <your url>:

• Press Apply, then OK.

• To start Chrome at Windows startup, copy this shortcut and paste it into the Startup folder (Start -> Program -> Startup).

output.path

Local disk directory to store all your output files (Absolute path).

Example: path.join(__dirname, "build/")

Webpack will output everything into localdisk/path-to-your-project/build/

output.publicPath

Where you uploaded your bundled files. (absolute path, or relative to main HTML file)

Example: /assets/

Assumed you deployed the app at server root http://server/.

By using /assets/, the app will find webpack assets at: http://server/assets/. Under the hood, every urls that webpack encounters will be re-written to begin with "/assets/".

It's really useful for ArgumentException and its derivatives:

public string DoSomething(string input) 
{
    if(input == null) 
    {
        throw new ArgumentNullException(nameof(input));
    }
    ...

Now if someone refactors the name of the input parameter the exception will be kept up to date too.

It is also useful in some places where previously reflection had to be used to get the names of properties or parameters.

In your example nameof(T) gets the name of the type parameter - this can be useful too:

throw new ArgumentException(nameof(T), $"Type {typeof(T)} does not support this method.");

Another use of nameof is for enums - usually if you want the string name of an enum you use .ToString():

enum MyEnum { ... FooBar = 7 ... }

Console.WriteLine(MyEnum.FooBar.ToString());

> "FooBar"

This is actually relatively slow as .Net holds the enum value (i.e. 7) and finds the name at run time.

Instead use nameof:

Console.WriteLine(nameof(MyEnum.FooBar))

> "FooBar"

Now .Net replaces the enum name with a string at compile time.

Yet another use is for things like INotifyPropertyChanged and logging - in both cases you want the name of the member that you're calling to be passed to another method:

// Property with notify of change
public int Foo
{
    get { return this.foo; }
    set
    {
        this.foo = value;
        PropertyChanged(this, new PropertyChangedEventArgs(nameof(this.Foo));
    }
}

Or...

// Write a log, audit or trace for the method called
void DoSomething(... params ...)
{
    Log(nameof(DoSomething), "Message....");
}

User can use this

Dim todaysdate As String = String.Format("{0:dd/MM/yyyy}", DateTime.Now)

this will format the date as required whereas user can change the string type dd/MM/yyyy or MM/dd/yyyy or yyyy/MM/dd or even can have this format to get the time from date

yyyy/MM/dd HH:mm:ss 

Give selected attribute to all options like this

$('#countries option').attr('selected', 'selected');

Usage:

$('#select_all').click( function() {
    $('#countries option').attr('selected', 'selected');
});

Update

In case you are using 1.6+, better option would be to use .prop() instead of .attr()

$('#select_all').click( function() {
    $('#countries option').prop('selected', true);
});

I don't know about the Android specifics for ssl certificates, but it would make sense that Android won't accept a self signed ssl certificate off the bat. I found this post from android forums which seems to be addressing the same issue: http://androidforums.com/android-applications/950-imap-self-signed-ssl-certificates.html

Since you're trying to "test some class code," I'd really recommend learning to use QTestLib. It provides a QTest namespace and a QtTest module that contain a number of useful functions and objects, including QSignalSpy that you can use to verify that certain signals are emitted.

Since you will eventually be integrating with a full GUI, using QTestLib and testing without sleeping or waiting will give you a more accurate test -- one that better represents the true usage patterns. But, should you choose not to go that route, you could use QTestLib::qSleep to do what you've requested.

Since you just need a pause between starting your pump and shutting it down, you could easily use a single shot timer:

class PumpTest: public QObject {
    Q_OBJECT
    Pump &pump;
public:
    PumpTest(Pump &pump):pump(pump) {};
public slots:
    void start() { pump.startpump(); }
    void stop() { pump.stoppump(); }
    void stopAndShutdown() {
        stop();
        QCoreApplication::exit(0);
    }
    void test() {
        start();
        QTimer::singleShot(1000, this, SLOT(stopAndShutdown));
    }
};

int main(int argc, char* argv[]) {
    QCoreApplication app(argc, argv);
    Pump p;
    PumpTest t(p);
    t.test();
    return app.exec();
}

But qSleep() would definitely be easier if all you're interested in is verifying a couple of things on the command line.

EDIT: Based on the comment, here's the required usage patterns.

First, you need to edit your .pro file to include qtestlib:

CONFIG += qtestlib

Second, you need to include the necessary files:

• For the QTest namespace (which includes qSleep): #include <QTest>
• For all the items in the QtTest module: #include <QtTest>. This is functionally equivalent to adding an include for each item that exists within the namespace.

For those who are searching for a light answer, you can get a simple working example from here:

html {
    position: relative;
    min-height: 100%;
}
body {
    margin-bottom: 60px /* Height of the footer */
}
footer {
    position: absolute;
    bottom: 0;
    width: 100%;
    height: 60px /* Example value */
}

Just play with the body's margin-bottom for adding space between the content and footer.

Yeah, why type extra lines each time; agreed. You can redirect the returned from a command to input by pipeline, but redirecting printed output to input (1>&0) is nope, at least not for multiple line outputs. Also you won't want to write a function again and again in each file for the same. So let's try something else.

A simple workaround would be to use printf function to store values in a variable.

printf -v myoutput "`cmd`"

such as

printf -v var "`echo ok;
  echo fine;
  echo thankyou`"
echo "$var" # don't forget the backquotes and quotes in either command.

Another customizable general solution (I myself use) for running the desired command only once and getting multi-line printed output of the command in an array variable line-by-line.

If you are not exporting the files anywhere and intend to use it locally only, you can have Terminal set-up the function declaration. You have to add the function in ~/.bashrc file or in ~/.profile file. In second case, you need to enable Run command as login shell from Edit>Preferences>yourProfile>Command.

Make a simple function, say:

get_prev() # preferably pass the commands in quotes. Single commands might still work without.
{
    # option 1: create an executable with the command(s) and run it
    #echo $* > /tmp/exe
    #bash /tmp/exe > /tmp/out
    
    # option 2: if your command is single command (no-pipe, no semi-colons), still it may not run correct in some exceptions.
    #echo `"$*"` > /tmp/out
    
    # option 3: (I actually used below)
    eval "$*" > /tmp/out # or simply "$*" > /tmp/out
    
    # return the command(s) outputs line by line
    IFS=$(echo -en "\n\b")
    arr=()
    exec 3</tmp/out
    while read -u 3 -r line
    do
        arr+=($line)
        echo $line
    done
    exec 3<&-
}

So what we did in option 1 was print the whole command to a temporary file /tmp/exe and run it and save the output to another file /tmp/out and then read the contents of the /tmp/out file line-by-line to an array. Similar in options 2 and 3, except that the commands were exectuted as such, without writing to an executable to be run.

In main script:

#run your command:

cmd="echo hey ya; echo hey hi; printf `expr 10 + 10`'\n' ; printf $((10 + 20))'\n'"
get_prev $cmd

#or simply
get_prev "echo hey ya; echo hey hi; printf `expr 10 + 10`'\n' ; printf $((10 + 20))'\n'"

Now, bash saves the variable even outside previous scope, so the arr variable created in get_prev function is accessible even outside the function in the main script:

#get previous command outputs in arr
for((i=0; i<${#arr[@]}; i++))
do
    echo ${arr[i]}
done

#if you're sure that your output won't have escape sequences you bother about, you may simply print the array
printf "${arr[*]}\n"

Edit:

get_prev()
{
    usage()
    {
        echo "Usage: alphabet [ -h | --help ]
        [ -s | --sep SEP ]

                echo " -h, --help : opens this help"
                echo " -s, --sep  : specify the separator, newline by default"
                echo " -v, --var  : variable name to put result into, arr by default"
                echo "  command   : command to execute. Enclose in quotes if multiple lines or pipelines are used."
                shift
                return 0
                ;;

                ;;
            -v|--var)
                shift
                var=$1
                shift
                ;;
            -|--)
                shift
                ;;
            *)
                cmd=$option
                ;;
        esac
    done
    if [ ${#} -eq 0 ]; then usage; return 1; fi
    
    ERROR=$( { eval "$*" > /tmp/out; } 2>&1 )
    if [ $ERROR ]; then echo $ERROR; return 1; fi
    
    local a=()
    exec 3</tmp/out
    while read -u 3 -r line
    do
        a+=($line)
    done
    exec 3<&-
    
    eval $var=\(\${a[@]}\)
    print_arr $var # comment this to suppress output
}

print()
{
    eval echo \${$1[@]}
}

print_arr()
{
    eval printf "%s\\\n" "\${$1[@]}"
}

Ive been using this to print space-separated outputs of multiple/pipelined/both commands as line separated:

get_prev -s " " -v myarr "cmd1 | cmd2; cmd3 | cmd4"

For example:

get_prev -s ' ' -v myarr whereis python # or "whereis python"
# can also be achieved (in this case) by
whereis python | tr ' ' '\n'

Now tr command is useful at other places as well, such as

echo $PATH | tr ':' '\n'

But for multiple/piped commands... you know now. :)

CoolAJ86's solution is correct and it does not compromise your security like disabling all checks using rejectUnauthorized or NODE_TLS_REJECT_UNAUTHORIZED. Still, you may need to inject an additional CA's certificate explicitly.

I tried first the root CAs included by the ssl-root-cas module:

require('ssl-root-cas/latest')
  .inject();

I still ended up with the UNABLE_TO_VERIFY_LEAF_SIGNATURE error. Then I found out who issued the certificate for the web site I was connecting to by the COMODO SSL Analyzer, downloaded the certificate of that authority and tried to add only that one:

require('ssl-root-cas/latest')
  .addFile(__dirname + '/comodohigh-assurancesecureserverca.crt');

I ended up with another error: CERT_UNTRUSTED. Finally, I injected the additional root CAs and included "my" (apparently intermediary) CA, which worked:

require('ssl-root-cas/latest')
  .inject()
  .addFile(__dirname + '/comodohigh-assurancesecureserverca.crt');

It seem to ignore the settings for the current active transaction, it only apply settings to a new transaction:

org.springframework.transaction.PlatformTransactionManager
TransactionStatus getTransaction(TransactionDefinition definition)
                         throws TransactionException
Return a currently active transaction or create a new one, according to the specified propagation behavior.
Note that parameters like isolation level or timeout will only be applied to new transactions, and thus be ignored when participating in active ones.
Furthermore, not all transaction definition settings will be supported by every transaction manager: A proper transaction manager implementation should throw an exception when unsupported settings are encountered.
An exception to the above rule is the read-only flag, which should be ignored if no explicit read-only mode is supported. Essentially, the read-only flag is just a hint for potential optimization.

Performance test for in_array vs array_intersect:

$a2 = array(3,20);

$intersect_times = array();
$in_array_times = array();
for($j = 0; $j < 10; $j++)
{
    /***** TEST ONE array_intersect *******/
    $t = microtime(true);
    for($i = 0; $i < 100000; $i++)
    {
        $x = array_intersect($a1,$a2);
        $x = empty($x);
    }
    $intersect_times[] = microtime(true) - $t;


    /***** TEST TWO in_array *******/
    $t2 = microtime(true);
    for($i = 0; $i < 100000; $i++)
    {
        $x = false;
        foreach($a2 as $v){
            if(in_array($v,$a1))
            {
                $x = true;
                break;
            }
        }
    }
    $in_array_times[] = microtime(true) - $t2;
}

echo '<hr><br>'.implode('<br>',$intersect_times).'<br>array_intersect avg: '.(array_sum($intersect_times) / count($intersect_times));

A little error checking goes a long way -- you can always test the value of errno or call perror() or strerror() to get more information about why the fopen() call failed.

Otherwise the suggestions about checking the path are probably correct... most likely you're not in the directory you think you are from the IDE and don't have the permissions you expect.

No, you cannot set them all in a single statement.
At the general case, you need at least three properties:

border-color: red green white blue;
border-style: solid dashed dotted solid;
border-width: 1px 2px 3px 4px;

However, that would be quite messy. It would be more readable and maintainable with four:

border-top:    1px solid  #ff0;
border-right:  2px dashed #f0F;
border-bottom: 3px dotted #f00;
border-left:   5px solid  #09f;

I accessed that certificate on apple's developer website and after downloaded it I opened it. Likewise, at open I got a little window asking if I wanted to add the certificate to keychain. Just tapped "add" and the "missing private key" error was gone.

As of 2019_10_10 I have NOT tested it, but there is the "GPU Ocelot" project

http://gpuocelot.gatech.edu/

that according to its advertisement tries to compile CUDA code for a variety of targets, including AMD GPUs.

An alternate I would suggest in this use case is to use the MAX(t_stamp) to get the latest row ... e.g.

select t.* from raceway_input_labo t
where t.t_stamp = (select max(t_stamp) from raceway_input_labo) 
limit 1

My coding pattern preference (perhaps) - reliable, generally performs at or better than trying to select the 1st row from a sorted list - also the intent is more explicitly readable.
Hope this helps ...

SQLer

You can use .indexOf() and .substr() like this:

var val = $("input").val();
var myString = val.substr(val.indexOf("?") + 1)

You can test it out here. If you're sure of the format and there's only one question mark, you can just do this:

var myString = $("input").val().split("?").pop();

You can use .css() to get the value of "visibility":

 if( ! ( $("#singlechatpanel-1").css('visibility') === "hidden")){
 }

http://api.jquery.com/css/

Yet another option would be:

SELECT * FROM mytable
 WHERE TRUNC(mydate, 'YEAR') = TRUNC(SYSDATE, 'YEAR');

You can convert the value to a date using a formula like this, next to the cell:

=DATE(LEFT(A1,4),MID(A1,5,2),RIGHT(A1,2))

Where A1 is the field you need to convert.

Alternatively, you could use this code in VBA:

Sub ConvertYYYYMMDDToDate()
   Dim c As Range
   For Each c In Selection.Cells
       c.Value = DateSerial(Left(c.Value, 4), Mid(c.Value, 5, 2), Right(c.Value, 2))
       'Following line added only to enforce the format.
       c.NumberFormat = "mm/dd/yyyy"
   Next
End Sub

Just highlight any cells you want fixed and run the code.

Note as RJohnson mentioned in the comments, this code will error if one of your selected cells is empty. You can add a condition on c.value to skip the update if it is blank.

Using Linq ...

List<string> listofIDs = collection.AllKeys.ToList();  
List<int> myStringList = listofIDs.Select(s => int.Parse(s)).ToList();

Take a look at fluent, it supports almost everything LINQ does and based on iterables - so it works with maps, generator functions, arrays, everything iterable.

The answer of JasonW is fine. But since apache httpd 2.4.6 there is a alternative: mod_remoteip

All what you must do is:

1. May be you must install the mod_remoteip package

2. Enable the module:

   LoadModule remoteip_module modules/mod_remoteip.so
   

3. Add the following to your apache httpd config. Note that you must add this line not into the configuration of the proxy server. You must add this to the configuration of the proxy target httpd server (the server behind the proxy):

   RemoteIPHeader X-Forwarded-For
   

See at http://httpd.apache.org/docs/trunk/mod/mod_remoteip.html for more informations and more options.

The MODERN approach is to consider cases where column of information come from a web service such as an OData source. If you need to generate a filter select fields off of massive data that has replicated values for the column, consider the code below:

var CatalogURL = getweb(currenturl)
                 +"/_api/web/lists/getbytitle('Site%20Inventory%20and%20Assets')/items?$select=Expense_x005F_x0020_Type&$orderby=Expense_x005F_x0020_Type";

/* the column that is replicated, is ordered by <column_name> */

    OData.read(CatalogURL,
        function(data,request){

            var myhtml ="";
            var myValue ="";

            for(var i = 0; i < data.results.length; i++)
            {
                myValue = data.results[i].Expense_x005F_x0020_Type;

                if(i == 0)
                {
                        myhtml += "<option value='"+myValue+"'>"+myValue+"</option>";
                }
                else
                if(myValue != data.results[i-1].Expense_x005F_x0020_Type)
                {
                        myhtml += "<option value='"+myValue+"'>"+myValue+"</option>";

                }
                else
                {

                }


            }

            $("#mySelect1").append(myhtml);

        });

You need other headers, not only access-control-allow-origin. If your request have the "Access-Control-Allow-Origin" header, you must copy it into the response headers, If doesn't, you must check the "Origin" header and copy it into the response. If your request doesn't have Access-Control-Allow-Origin not Origin headers, you must return "*".

You can read the complete explanation here: http://www.html5rocks.com/en/tutorials/cors/#toc-adding-cors-support-to-the-server

and this is the function I'm using to write cross domain headers:

func writeCrossDomainHeaders(w http.ResponseWriter, req *http.Request) {
    // Cross domain headers
    if acrh, ok := req.Header["Access-Control-Request-Headers"]; ok {
        w.Header().Set("Access-Control-Allow-Headers", acrh[0])
    }
    w.Header().Set("Access-Control-Allow-Credentials", "True")
    if acao, ok := req.Header["Access-Control-Allow-Origin"]; ok {
        w.Header().Set("Access-Control-Allow-Origin", acao[0])
    } else {
        if _, oko := req.Header["Origin"]; oko {
            w.Header().Set("Access-Control-Allow-Origin", req.Header["Origin"][0])
        } else {
            w.Header().Set("Access-Control-Allow-Origin", "*")
        }
    }
    w.Header().Set("Access-Control-Allow-Methods", "GET, POST, PUT, DELETE")
    w.Header().Set("Connection", "Close")

}

You are using a forward declaration for the type MainWindowClass. That's fine, but it also means that you can only declare a pointer or reference to that type. Otherwise the compiler has no idea how to allocate the parent object as it doesn't know the size of the forward declared type (or if it actually has a parameterless constructor, etc.)

So, you either want:

// forward declaration, details unknown
class A;

class B {
  A *a;  // pointer to A, ok
};

Or, if you can't use a pointer or reference....

// declaration of A
#include "A.h"

class B {
  A a;  // ok, declaration of A is known
};

At some point, the compiler needs to know the details of A.

If you are only storing a pointer to A then it doesn't need those details when you declare B. It needs them at some point (whenever you actually dereference the pointer to A), which will likely be in the implementation file, where you will need to include the header which contains the declaration of the class A.

// B.h
// header file

// forward declaration, details unknown
class A;

class B {
public: 
    void foo();
private:
  A *a;  // pointer to A, ok
};

// B.cpp
// implementation file

#include "B.h"
#include "A.h"  // declaration of A

B::foo() {
    // here we need to know the declaration of A
    a->whatever();
}
