This pen I found the other day seemed to do it beautifully, just a bit of css and 21 lines of javascript. I hadn't heard of the cloneNode js command until I found this, but it totally worked for what I needed for sure.

http://codepen.io/rikschennink/pen/zvcgx

Detail: A. Basically it looks at your content div and invokes a cloneNode on it so it creates a duplicate which it then places inside the overflow:hidden header object sitting on top of the page. B. Then it simply listens for scrolling so that both images seem to match and blurs the header image... annnnd BAM. Effect achieved.

Not really fully do-able in CSS until they get the lil bit of scriptability built into the language.

you can do this with css3, this blurs the whole element

div (or whatever element) {
  -webkit-filter: blur(5px);
  -moz-filter: blur(5px);
  -o-filter: blur(5px);
  -ms-filter: blur(5px);
  filter: blur(5px);
}

Fiddle: http://jsfiddle.net/H4DU4/

jsfiddle

.blur-bgimage {
    overflow: hidden;
    margin: 0;
    text-align: left;
}
.blur-bgimage:before {
    content: "";
    position: absolute;
    width : 100%;
    height: 100%;
    background: inherit;
    z-index: -1;

    filter        : blur(10px);
    -moz-filter   : blur(10px);
    -webkit-filter: blur(10px);
    -o-filter     : blur(10px);

    transition        : all 2s linear;
    -moz-transition   : all 2s linear;
    -webkit-transition: all 2s linear;
    -o-transition     : all 2s linear;
}

You can blur the body background image by using the body's :before pseudo class to inherit the image and then blurring it. Wrap all that into a class and use javascript to add and remove the class to blur and unblur.

background: rgba(255,255,255,0.5);
backdrop-filter: blur(5px);

Instead of adding another blur background to your content, you can use backdrop-filter. FYI IE 11 and Firefox may not support it. Check caniuse.

Demo:

header {_x000D_
  position: fixed;_x000D_
  width: 100%;_x000D_
  padding: 10px;_x000D_
  background: rgba(255,255,255,0.5);_x000D_
  backdrop-filter: blur(5px);_x000D_
}_x000D_
body {_x000D_
  margin: 0;_x000D_
}

<header>_x000D_
  Header_x000D_
</header>_x000D_
<div>_x000D_
  <img src="https://dummyimage.com/600x400/000/fff" />_x000D_
  <img src="https://dummyimage.com/600x400/000/fff" />_x000D_
  <img src="https://dummyimage.com/600x400/000/fff" />_x000D_
</div>

That should do it for ya.

In this document Google JSON Style Guide (recommendations for building JSON APIs at Google),

It recommends that:

1. Property names must be camelCased, ASCII strings.

2. The first character must be a letter, an underscore (_) or a dollar sign ($).

Example:

{
  "thisPropertyIsAnIdentifier": "identifier value"
}

My team follows this convention.

Assigning Comparison to property value

JavaScript

You could assign the comparison of the property to "1"

obj["isChecked"] = (obj["isChecked"]==="1");

This only evaluates for a String value of "1" though. Other variables evaulate to false like an actual typeof number would be false. (i.e. obj["isChecked"]=1)

If you wanted to be indiscrimate about "1" or 1, you could use:

obj["isChecked"] = (obj["isChecked"]=="1");

Example Outputs

console.log(obj["isChecked"]==="1"); // true
console.log(obj["isChecked"]===1); // false
console.log(obj["isChecked"]==1); // true
console.log(obj["isChecked"]==="0"); // false
console.log(obj["isChecked"]==="Elephant"); // false

PHP

Same concept in PHP

$obj["isChecked"] = ($obj["isChecked"] == "1");

The same operator limitations as stated above for JavaScript apply.

Double Not

The 'double not' also works. It's confusing when people first read it but it works in both languages for integer/number type values. It however does not work in JavaScript for string type values as they always evaluate to true:

JavaScript

!!"1"; //true
!!"0"; //true
!!1; //true
!!0; //false
!!parseInt("0",10); // false

PHP

echo !!"1"; //true
echo !!"0"; //false
echo !!1; //true
echo !!0; //false

When calling a function, the word "this" is a reference to the object that called the function.

In your example, it is a reference to the anchor element. At the other end, the function call then access member variables of the element through the parameter that was passed.

If one is on a Windows machine and in PowerShell, one needs to quote the argument such as:

git stash apply "stash@{0}"

...or to apply the changes and remove from the stash:

git stash pop "stash@{0}"

Otherwise without the quotes you might get this error:

fatal: ambiguous argument 'stash@': unknown revision or path not in the working tree.

JSP implicit objects likes session, request etc. are not available inside JSP declaration <%! %> tags.

You could use it directly in your expression as

<td>Username: </td>
<td><input type="text" value="<%= session.getAttribute("username") %>" /></td>

On other note, using scriptlets in JSP has been long deprecated. Use of EL (expression language) and JSTL tags is highly recommended. For example, here you could use EL as

<td>Username: </td>
<td><input type="text" value="${username}" /></td>

The best part is that scope resolution is done automatically. So, here username could come from page, or request, or session, or application scopes in that order. If for a particular instance you need to override this because of a name collision you can explicitly specify the scope as

<td><input type="text" value="${requestScope.username}" /></td> or,
<td><input type="text" value="${sessionScope.username}" /></td> or,
<td><input type="text" value="${applicationScope.username}" /></td>

As far as I have understood your question, you have listed two issues.

PROBLEM 1:

You are not able to execute the Python scripts by double clicking the Python file in Windows.

REASON:

The script runs too fast to be seen by the human eye.

SOLUTION:

Add input() in the bottom of your script and then try executing it with double click. Now the cmd will be open until you close it.

EXAMPLE:

print("Hello World")
input()

PROBLEM 2:

./ issue

SOLUTION:

Use Tab to autocomplete the filenames rather than manually typing the filename with ./ autocomplete automatically fills all this for you.

USAGE:

CD into the directory in which .py files are present and then assume the filename is test.py then type python te and then press Tab, it will be automatically converted to python ./test.py.

@Jan Kuiken's answer is certainly well-thought and thorough, but there are some caveats:

• it does not work in all cases
• it requires a fair amount of extra code
• it may vary considerably from one plot to the next

A much simpler approach is to annotate the last point of each plot. The point can also be circled, for emphasis. This can be accomplished with one extra line:

from matplotlib import pyplot as plt

for i, (x, y) in enumerate(samples):
    plt.plot(x, y)
    plt.text(x[-1], y[-1], 'sample {i}'.format(i=i))

A variant would be to use ax.annotate.

You can insert an image that looks like a button. Then attach a script to the image.

• INSERT menu
• Image

You can insert any image. The image can be edited in the spreadsheet

Image of a Button

Assign a function name to an image:

Checkout intent properties like no history , clear back stack etc ... Intent.setFlags

Intent mStartActivity = new Intent(HomeActivity.this, SplashScreen.class);
int mPendingIntentId = 123456;
PendingIntent mPendingIntent = PendingIntent.getActivity(HomeActivity.this, mPendingIntentId, mStartActivity,
PendingIntent.FLAG_CANCEL_CURRENT);
AlarmManager mgr = (AlarmManager) HomeActivity.this.getSystemService(Context.ALARM_SERVICE);
mgr.set(AlarmManager.RTC, System.currentTimeMillis() + 100, mPendingIntent);
System.exit(0);

I would use:

self.childView.center = CGPointMake(CGRectGetMidX(self.parentView.bounds),
                                    CGRectGetMidY(self.parentView.bounds));

I like to use the CGRect options...

SWIFT 3:

self.childView.center = CGPoint(x: self.parentView.bounds.midX,
                                        y: self.parentView.bounds.midY);

This is not possible from HTML on. The closest what you can get is the accept-charset attribute of the <form>. Only MSIE browser adheres that, but even then it is doing it wrong (e.g. CP1252 is actually been used when it says that it has sent ISO-8859-1). Other browsers are fully ignoring it and they are using the charset as specified in the Content-Type header of the response. Setting the character encoding right is basically fully the responsiblity of the server side. The client side should just send it back in the same charset as the server has sent the response in.

To the point, you should really configure the character encoding stuff entirely from the server side on. To overcome the inability to edit URIEncoding attribute, someone here on SO wrote a (complex) filter: Detect the URI encoding automatically in Tomcat. You may find it useful as well (note: I haven't tested it).

Update: Noted should be that the meta tag as given in your question is ignored when the content is been transferred over HTTP. Instead, the HTTP response Content-Type header will be used to determine the content type and character encoding. You can determine the HTTP header with for example Firebug, in the Net panel.

I'd go for jpeg. Read this post regarding image size reduction and after deciding on the technique, use ImageMagick

Hope this helps

If you don't want to grant admin permission to dashboard service account, you can create cluster admin service account.

$ kubectl create serviceaccount cluster-admin-dashboard-sa
$ kubectl create clusterrolebinding cluster-admin-dashboard-sa \
  --clusterrole=cluster-admin \
  --serviceaccount=default:cluster-admin-dashboard-sa

And then, you can use the token of just created cluster admin service account.

$ kubectl get secret | grep cluster-admin-dashboard-sa
cluster-admin-dashboard-sa-token-6xm8l   kubernetes.io/service-account-token   3         18m
$ kubectl describe secret cluster-admin-dashboard-sa-token-6xm8l

Add a spinner to the XML layout, and then add this code to the Java file:

Spinner spinner;
spinner = (Spinner) findViewById(R.id.spinner1) ;
java.util.ArrayList<String> strings = new java.util.ArrayList<>();
strings.add("Mobile") ;
strings.add("Home");
strings.add("Work");
SpinnerAdapter spinnerAdapter = new SpinnerAdapter(AddMember.this, R.layout.support_simple_spinner_dropdown_item, strings);
spinner.setAdapter(spinnerAdapter);

Try to use getActivity(); This will solve your problem.

I believe the following should work with many well-behaved classed in Python:

def copy(obj):
    return type(obj)(obj)

(Of course, I am not talking here about "deep copies," which is a different story, and which may be not a very clear concept -- how deep is deep enough?)

According to my tests with Python 3, for immutable objects, like tuples or strings, it returns the same object (because there is no need to make a shallow copy of an immutable object), but for lists or dictionaries it creates an independent shallow copy.

Of course this method only works for classes whose constructors behave accordingly. Possible use cases: making a shallow copy of a standard Python container class.

This is a peculiar question because it's not supposed to be a matter of choice.

When you launch the JVM, you specify a class to run, and it is the main() of this class where your program starts.

By init(), I assume you mean the JApplet method. When an applet is launched in the browser, the init() method of the specified applet is executed as the first order of business.

By run(), I assume you mean the method of Runnable. This is the method invoked when a new thread is started.

• main: program start
• init: applet start
• run: thread start

If Eclipse is running your run() method even though you have no main(), then it is doing something peculiar and non-standard, but not infeasible. Perhaps you should post a sample class that you've been running this way.

The logic is incorrect. It would always return the result of last element in the array.

remIndex = -1;

for (i = 0; i < remSize.length; i++) {      
    if (remSize[i].size == remData.size) {
        remIndex = i
        break;
    }
}

The "no version information available" means that the library version number is lower on the shared object. For example, if your major.minor.patch number is 7.15.5 on the machine where you build the binary, and the major.minor.patch number is 7.12.1 on the installation machine, ld will print the warning.

You can fix this by compiling with a library (headers and shared objects) that matches the shared object version shipped with your target OS. E.g., if you are going to install to RedHat 3.4.6-9 you don't want to compile on Debian 4.1.1-21. This is one of the reasons that most distributions ship for specific linux distro numbers.

Otherwise, you can statically link. However, you don't want to do this with something like PAM, so you want to actually install a development environment that matches your client's production environment (or at least install and link against the correct library versions.)

Advice you get to rename the .so files (padding them with version numbers,) stems from a time when shared object libraries did not use versioned symbols. So don't expect that playing with the .so.n.n.n naming scheme is going to help (much - it might help if you system has been trashed.)

You last option will be compiling with a library with a different minor version number, using a custom linking script: http://www.redhat.com/docs/manuals/enterprise/RHEL-4-Manual/gnu-linker/scripts.html

To do this, you'll need to write a custom script, and you'll need a custom installer that runs ld against your client's shared objects, using the custom script. This requires that your client have gcc or ld on their production system.

I would avoid to do a query for each entry.

if(is_array($EMailArr)){

    $sql = "INSERT INTO email_list (R_ID, EMAIL, NAME) values ";

    $valuesArr = array();
    foreach($EMailArr as $row){

        $R_ID = (int) $row['R_ID'];
        $email = mysql_real_escape_string( $row['email'] );
        $name = mysql_real_escape_string( $row['name'] );

        $valuesArr[] = "('$R_ID', '$email', '$name')";
    }

    $sql .= implode(',', $valuesArr);

    mysql_query($sql) or exit(mysql_error()); 
}

If using PHP there is a much easier way to do this using pcntl_fork:

http://www.php.net/manual/en/function.pcntl-fork.php

Another possible solution which I think is more semantically correct is to change the floated inner elements to be 'display: inline'. This example and what I was working on when I came across this page both use floated divs in much exactly the same way that a span would be used. Instead of using divs, switch to span, or if you are using another element which is by default 'display: block' instead of 'display: inline' then change it to be 'display: inline'. I believe this is the 100% semantically correct solution.

Solution 1, floating the parent, is essentially to change the entire document to be floated.

Solution 2, setting an explicit height, is like drawing a box and saying I want to put a picture here, i.e. use this if you are doing an img tag.

Solution 3, adding a spacer to clear float, is like adding an extra line below your content and will mess with surrounding elements too. If you use this approach you probably want to set the div to be height: 0px.

Solution 4, overflow: auto, is acknowledging that you don't know how to lay out the document and you are admitting that you don't know what to do.

There are many ways to wait in Unity. It is really simple but I think it's worth covering most ways to do these:

1.With a coroutine and WaitForSeconds.

The is by far the simplest way. Put all the code that you need to wait for some time in a coroutine function then you can wait with WaitForSeconds. Note that in coroutine function, you call the function with StartCoroutine(yourFunction).

Example below will rotate 90 deg, wait for 4 seconds, rotate 40 deg and wait for 2 seconds, and then finally rotate rotate 20 deg.

void Start()
{
    StartCoroutine(waiter());
}

IEnumerator waiter()
{
    //Rotate 90 deg
    transform.Rotate(new Vector3(90, 0, 0), Space.World);

    //Wait for 4 seconds
    yield return new WaitForSeconds(4);

    //Rotate 40 deg
    transform.Rotate(new Vector3(40, 0, 0), Space.World);

    //Wait for 2 seconds
    yield return new WaitForSeconds(2);

    //Rotate 20 deg
    transform.Rotate(new Vector3(20, 0, 0), Space.World);
}

2.With a coroutine and WaitForSecondsRealtime.

The only difference between WaitForSeconds and WaitForSecondsRealtime is that WaitForSecondsRealtime is using unscaled time to wait which means that when pausing a game with Time.timeScale, the WaitForSecondsRealtime function would not be affected but WaitForSeconds would.

void Start()
{
    StartCoroutine(waiter());
}

IEnumerator waiter()
{
    //Rotate 90 deg
    transform.Rotate(new Vector3(90, 0, 0), Space.World);

    //Wait for 4 seconds
    yield return new WaitForSecondsRealtime(4);

    //Rotate 40 deg
    transform.Rotate(new Vector3(40, 0, 0), Space.World);

    //Wait for 2 seconds
    yield return new WaitForSecondsRealtime(2);

    //Rotate 20 deg
    transform.Rotate(new Vector3(20, 0, 0), Space.World);
}

Wait and still be able to see how long you have waited:

3.With a coroutine and incrementing a variable every frame with Time.deltaTime.

A good example of this is when you need the timer to display on the screen how much time it has waited. Basically like a timer.

It's also good when you want to interrupt the wait/sleep with a boolean variable when it is true. This is where yield break; can be used.

bool quit = false;

void Start()
{
    StartCoroutine(waiter());
}

IEnumerator waiter()
{
    float counter = 0;
    //Rotate 90 deg
    transform.Rotate(new Vector3(90, 0, 0), Space.World);

    //Wait for 4 seconds
    float waitTime = 4;
    while (counter < waitTime)
    {
        //Increment Timer until counter >= waitTime
        counter += Time.deltaTime;
        Debug.Log("We have waited for: " + counter + " seconds");
        //Wait for a frame so that Unity doesn't freeze
        //Check if we want to quit this function
        if (quit)
        {
            //Quit function
            yield break;
        }
        yield return null;
    }

    //Rotate 40 deg
    transform.Rotate(new Vector3(40, 0, 0), Space.World);

    //Wait for 2 seconds
    waitTime = 2;
    //Reset counter
    counter = 0;
    while (counter < waitTime)
    {
        //Increment Timer until counter >= waitTime
        counter += Time.deltaTime;
        Debug.Log("We have waited for: " + counter + " seconds");
        //Check if we want to quit this function
        if (quit)
        {
            //Quit function
            yield break;
        }
        //Wait for a frame so that Unity doesn't freeze
        yield return null;
    }

    //Rotate 20 deg
    transform.Rotate(new Vector3(20, 0, 0), Space.World);
}

You can still simplify this by moving the while loop into another coroutine function and yielding it and also still be able to see it counting and even interrupt the counter.

bool quit = false;

void Start()
{
    StartCoroutine(waiter());
}

IEnumerator waiter()
{
    //Rotate 90 deg
    transform.Rotate(new Vector3(90, 0, 0), Space.World);

    //Wait for 4 seconds
    float waitTime = 4;
    yield return wait(waitTime);

    //Rotate 40 deg
    transform.Rotate(new Vector3(40, 0, 0), Space.World);

    //Wait for 2 seconds
    waitTime = 2;
    yield return wait(waitTime);

    //Rotate 20 deg
    transform.Rotate(new Vector3(20, 0, 0), Space.World);
}

IEnumerator wait(float waitTime)
{
    float counter = 0;

    while (counter < waitTime)
    {
        //Increment Timer until counter >= waitTime
        counter += Time.deltaTime;
        Debug.Log("We have waited for: " + counter + " seconds");
        if (quit)
        {
            //Quit function
            yield break;
        }
        //Wait for a frame so that Unity doesn't freeze
        yield return null;
    }
}

Wait/Sleep until variable changes or equals to another value:

4.With a coroutine and the WaitUntil function:

Wait until a condition becomes true. An example is a function that waits for player's score to be 100 then loads the next level.

float playerScore = 0;
int nextScene = 0;

void Start()
{
    StartCoroutine(sceneLoader());
}

IEnumerator sceneLoader()
{
    Debug.Log("Waiting for Player score to be >=100 ");
    yield return new WaitUntil(() => playerScore >= 10);
    Debug.Log("Player score is >=100. Loading next Leve");

    //Increment and Load next scene
    nextScene++;
    SceneManager.LoadScene(nextScene);
}

5.With a coroutine and the WaitWhile function.

Wait while a condition is true. An example is when you want to exit app when the escape key is pressed.

void Start()
{
    StartCoroutine(inputWaiter());
}

IEnumerator inputWaiter()
{
    Debug.Log("Waiting for the Exit button to be pressed");
    yield return new WaitWhile(() => !Input.GetKeyDown(KeyCode.Escape));
    Debug.Log("Exit button has been pressed. Leaving Application");

    //Exit program
    Quit();
}

void Quit()
{
    #if UNITY_EDITOR
    UnityEditor.EditorApplication.isPlaying = false;
    #else
    Application.Quit();
    #endif
}

6.With the Invoke function:

You can call tell Unity to call function in the future. When you call the Invoke function, you can pass in the time to wait before calling that function to its second parameter. The example below will call the feedDog() function after 5 seconds the Invoke is called.

void Start()
{
    Invoke("feedDog", 5);
    Debug.Log("Will feed dog after 5 seconds");
}

void feedDog()
{
    Debug.Log("Now feeding Dog");
}

7.With the Update() function and Time.deltaTime.

It's just like #3 except that it does not use coroutine. It uses the Update function.

The problem with this is that it requires so many variables so that it won't run every time but just once when the timer is over after the wait.

float timer = 0;
bool timerReached = false;

void Update()
{
    if (!timerReached)
        timer += Time.deltaTime;

    if (!timerReached && timer > 5)
    {
        Debug.Log("Done waiting");
        feedDog();

        //Set to false so that We don't run this again
        timerReached = true;
    }
}

void feedDog()
{
    Debug.Log("Now feeding Dog");
}

There are still other ways to wait in Unity but you should definitely know the ones mentioned above as that makes it easier to make games in Unity. When to use each one depends on the circumstances.

For your particular issue, this is the solution:

IEnumerator showTextFuntion()
{
    TextUI.text = "Welcome to Number Wizard!";
    yield return new WaitForSeconds(3f);
    TextUI.text = ("The highest number you can pick is " + max);
    yield return new WaitForSeconds(3f);
    TextUI.text = ("The lowest number you can pick is " + min);
}

And to call/start the coroutine function from your start or Update function, you call it with

StartCoroutine (showTextFuntion());

Excuse me when I answer your questions out-of-order, it makes it easier to understand this way.

When static variable is declared in a header file is its scope limited to .h file or across all units.

There is no such thing as a "header file scope". The header file gets included into source files. The translation unit is the source file including the text from the header files. Whatever you write in a header file gets copied into each including source file.

As such, a static variable declared in a header file is like a static variable in each individual source file.

Since declaring a variable static this way means internal linkage, every translation unit #includeing your header file gets its own, individual variable (which is not visible outside your translation unit). This is usually not what you want.

I would like to know what is the difference between static variables in a header file vs declared in a class.

In a class declaration, static means that all instances of the class share this member variable; i.e., you might have hundreds of objects of this type, but whenever one of these objects refers to the static (or "class") variable, it's the same value for all objects. You could think of it as a "class global".

Also generally static variable is initialized in .cpp file when declared in a class right ?

Yes, one (and only one) translation unit must initialize the class variable.

So that does mean static variable scope is limited to 2 compilation units ?

As I said:

• A header is not a compilation unit,
• static means completely different things depending on context.

Global static limits scope to the translation unit. Class static means global to all instances.

I hope this helps.

PS: Check the last paragraph of Chubsdad's answer, about how you shouldn't use static in C++ for indicating internal linkage, but anonymous namespaces. (Because he's right. ;-) )

If you need the result in a date format you can use:

Select Convert(DateTime, Convert(VarChar, GetDate(), 101))

Interesting problem. I'm guessing you just want to trigger some process or action on the other server, but don't care what the results are and want your script to continue. There is probably something in cURL that can make this happen, but you may want to consider using exec() to run another script on the server that does the call if cURL can't do it. (Typically people want the results of the script call so I'm not sure if PHP has the ability to just trigger the process.) With exec() you could run a wget or even another PHP script that makes the request with file_get_conents().

With that row

var element = {};

you define element to be a plain object. The native JavaScript object has no push() method. To add new items to a plain object use this syntax:

element[ yourKey ] = yourValue;

On the other hand you could define element as an array using

var element = [];

Then you can add elements using push().

And why don't you try with this ??? :

var itemsMax = items.Where(x => x.Height == items.Max(y => y.Height));

OR more optimise :

var itemMaxHeight = items.Max(y => y.Height);
var itemsMax = items.Where(x => x.Height == itemMaxHeight);

mmm ?

ATTENTION! the chosen answer contains a bug (Jac's answer).

if you have more than one cookie (very likely..) and the cookie you are retrieving is the first on the list, it doesn't set the variable "end" and therefore it will return the entire string of characters following the "cookieName=" within the document.cookie string!

here is a revised version of that function:

function getCookie( name ) {
    var dc,
        prefix,
        begin,
        end;

    dc = document.cookie;
    prefix = name + "=";
    begin = dc.indexOf("; " + prefix);
    end = dc.length; // default to end of the string

    // found, and not in first position
    if (begin !== -1) {
        // exclude the "; "
        begin += 2;
    } else {
        //see if cookie is in first position
        begin = dc.indexOf(prefix);
        // not found at all or found as a portion of another cookie name
        if (begin === -1 || begin !== 0 ) return null;
    } 

    // if we find a ";" somewhere after the prefix position then "end" is that position,
    // otherwise it defaults to the end of the string
    if (dc.indexOf(";", begin) !== -1) {
        end = dc.indexOf(";", begin);
    }

    return decodeURI(dc.substring(begin + prefix.length, end) ).replace(/\"/g, ''); 
}

num = raw_input ("Type Number : ")
search = open("file.txt","r")
for line in search.readlines():
    for digit in num:
        # Check if any of the digits provided by the user are in the line.
        if digit in line:
            print line
            continue

convert your batch file into .exe with this tool: http://www.battoexeconverter.com/ then you can run it as administrator

For me this was the default installation directory on Windows 7. Found it via Rusy's answer

This might work for you (GNU sed):

sed -r 's/^([^ ]+ ){2}//' file

or for columns separated by one or more white spaces:

sed -r 's/^(\S+\s+){2}//' file

Disabled means that no data from that form element will be submitted when the form is submitted. Read-only means any data from within the element will be submitted, but it cannot be changed by the user.

For example:

<input type="text" name="yourname" value="Bob" readonly="readonly" />

This will submit the value "Bob" for the element "yourname".

<input type="text" name="yourname" value="Bob" disabled="disabled" />

This will submit nothing for the element "yourname".

Don't have access to VisualStudio (I'm on my Mac), but using the information from http://bhaidar.net/cs/archive/2007/08/01/left-outer-join-in-linq-to-sql.aspx it looks like you may be able to do something like this:

var query = from o in dc.Orders
            join v in dc.Vendors on o.VendorId equals v.Id into ov
            from x in ov.DefaultIfEmpty()
            join s in dc.Status on o.StatusId equals s.Id into os
            from y in os.DefaultIfEmpty()
            select new { o.OrderNumber, x.VendorName, y.StatusName }

InnoDB works slightly different that MyISAM and they both are viable options. You should use what you think it fits the project.

Some keypoints will be:

1. InnoDB does ACID-compliant transaction. http://en.wikipedia.org/wiki/ACID
2. InnoDB does Referential Integrity (foreign key relations) http://www.w3resource.com/sql/joins/joining-tables-through-referential-integrity.php
3. MyIsam does full text search, InnoDB doesn't
4. I have been told InnoDB is faster on executing writes but slower than MyISAM doing reads (I cannot back this up and could not find any article that analyses this, I do however have the guy that told me this in high regard), feel free to ignore this point or do your own research.
5. Default configuration does not work very well for InnoDB needs to be tweaked accordingly, run a tool like http://mysqltuner.pl/mysqltuner.pl to help you.

Notes:

• In my opinion the second point is probably the one were InnoDB has a huge advantage over MyISAM.
• Full text search not working with InnoDB is a bit of a pain, You can mix different storage engines but be careful when doing so.

Notes2: - I am reading this book "High performance MySQL", the author says "InnoDB loads data and creates indexes slower than MyISAM", this could also be a very important factor when deciding what to use.

Your test requires a ServletContext: add @WebIntegrationTest

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class, loader = AnnotationConfigContextLoader.class)
@WebIntegrationTest
public class UserServiceImplIT

...or look here for other options: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html

UPDATE In Spring Boot 1.4.x and above @WebIntegrationTest is no longer preferred. @SpringBootTest or @WebMvcTest

I dont have prettier extension installed, but after reading the possible duplicate answer I've added from scratch in my User Setting (UserSetting.json, Ctrl+, shortcut):

"prettier.singleQuote": true

A part a green warning (Unknown configuration setting) the single quotes are no more replaced.

I suspect that the prettier extension is not visible but is embedded inside the Vetur extension.

var val = (string === "true");

Add current user to docker group:

If you can use a helper column, you can use the MATCH function to test if a value in one column exists in another column (or in another column on another worksheet). It will return an Error if there is no match

To simply identify duplicates, use a helper column

Assume data in Sheet1, Column A, and another list in Sheet2, Column A. In your helper column, row 1, place the following formula:

=If(IsError(Match(A1, 'Sheet2'!A:A,False)),"","Duplicate")

Drag/copy this forumla down, and it should identify the duplicates.

To highlight cells, use conditional formatting:

With some tinkering, you can use this MATCH function in a Conditional Formatting rule which would highlight duplicate values. I would probably do this instead of using a helper column, although the helper column is a great way to "see" results before you make the conditional formatting rule.

Something like:

=NOT(ISERROR(MATCH(A1, 'Sheet2'!A:A,FALSE)))

For Excel 2007 and prior, you cannot use conditional formatting rules that reference other worksheets. In this case, use the helper column and set your formatting rule in column A like:

=B1="Duplicate"

This screenshot is from the 2010 UI, but the same rule should work in 2007/2003 Excel.

The error says it all...

Msg 1033, Level 15, State 1, Procedure TestView, Line 5 The ORDER BY clause is invalid in views, inline functions, derived tables, subqueries, and common table expressions, unless TOP, OFFSET or FOR XML is also specified.

Don't use TOP 100 PERCENT, use TOP n, where N is a number

The TOP 100 PERCENT (for reasons I don't know) is ignored by SQL Server VIEW (post 2012 versions), but I think MS kept it for syntax reasons. TOP n is better and will work inside a view and sort it the way you want when a view is used initially, but be careful.

In my opinion, it's important to keep your construct vocabulary to a minimum. If I can do away with breaks and continues easily, I do so.

function foo ()
{
    var found = false;
    for(var k = 0; (k < 4 && !found); k++){
        for(var m = 0; (m < 4 && !found); m++){
           if( m === 2){
               found = true;
           }
        }
    }
    return found;
}

Be warned, after the loop, m and k are one larger that you might think. This is because m++ and k++ are executed before their loop conditions. However, it's still better than 'dirty' breaks.

EDIT: long comment @Dennis...

I wasn't being 100% serious about being 'dirty', but I still think that 'break' contravenes my own conception of clean code. The thought of having multi-level breaks actually makes me feel like taking a shower.

I find justifying what I mean about a feeling about code because I have coded all life. The best why I can think of it is is a combination of manners and grammar. Breaks just aren't polite. Multi level breaks are just plain rude.

When looking at a for statement, a reader knows exactly where to look. Everything you need to know about the rules of engagement are in the contract, in between the parenthesis. As a reader, breaks insult me, it feels like I've been cheated upon.

Clarity is much more respectful than cheating.

Whenever I do a merge, I get into the branch I want to merge into (e.g. "git checkout branch-i-am-working-in") and then do the following:

git merge origin/branch-i-want-to-merge-from

Check for missing folders that are required by the server, in my case it was UPLOADS folder in programData which was deleted by empty folder cleaner utility that I used earlier.

How did I find out:

run the server config file my.ini(in my case it was in programData) as the defaults-file param for mysqld (don't forget to use --console option to view error log on screen) 'mysqld --defaults-file="C:\ProgramData\MySQL\MySQL Server 8.0\my.ini" --console'

Error:

mysqld: Can't read dir of 'C:\ProgramData\MySQL\MySQL Server 8.0\Uploads\' (OS errno 2 - No such file or directory)

Solution:

Once I manually created the Uploads folder the server started successfully.

.h files will nothing to do with compiling ... you only care about cpp files... so type g++ filename1.cpp filename2.cpp main.cpp -o myprogram

means you are compiling each cpp files and then linked them together into myprgram.

then run your program ./myprogram

That probably means that your id is an AUTO_INCREMENT integer and you're trying to send a string. You should specify a column list and omit it from your INSERT.

INSERT INTO workorders (column1, column2) VALUES ($column1, $column2)

Watch the Tutorial https://www.youtube.com/watch?v=u92_73vfA8M

or

follow steps :

1. Go to any browser

2. type gradle and press enter

you can specify any version you want after the

gradle keyword

i am downloading gradle 3.3

3. https://services.gradle.org/distributions click on this link which is in description directly if you want

4. click on gradle 3.3 all.zip

5. wait for the download to complete

6. once the download is complete extract the file to the location

c://user/your pc name /.gradle/wrapper/dists

7. wait till extraction it takes 5 mins to complete

8. Now open your project in android studio

9.go to file > settings >bulid ,exec,deployment > gradle

10. now change use default gradle to

use local gradle distributn

select the location where you had extracted gradle 3.3.zip

C:\Users\your pc name.gradle\wrapper\dists\gradle-3.3

11. click on OK

12. Now build starts again and

you can see now the build is successful and error is resolved

 # print section of file based on line numbers

The directive can access any attribute that is defined on the same element, even if the directive itself is not the element.

Template:

<div example-directive example-number="99" example-function="exampleCallback()"></div>

Directive:

app.directive('exampleDirective ', function () {
    return {
        restrict: 'A',   // 'A' is the default, so you could remove this line
        scope: {
            callback : '&exampleFunction',
        },
        link: function (scope, element, attrs) {
            var num = scope.$eval(attrs.exampleNumber);
            console.log('number=',num);
            scope.callback();  // calls exampleCallback()
        }
    };
});

fiddle

If the value of attribute example-number will be hard-coded, I suggest using $eval once, and storing the value. Variable num will have the correct type (a number).

This one works for me, I first try to get UTC time, and then add or subtract hours according to the timezone you'd like to set.

today = datetime.utcnow()

Very fast & clean Java-method that doesn't rely on external libraries:

(Simply replace MD5 with SHA-1, SHA-256, SHA-384 or SHA-512 if you want those)

public String calcMD5() throws Exception{
        byte[] buffer = new byte[8192];
        MessageDigest md = MessageDigest.getInstance("MD5");

        DigestInputStream dis = new DigestInputStream(new FileInputStream(new File("Path to file")), md);
        try {
            while (dis.read(buffer) != -1);
        }finally{
            dis.close();
        }

        byte[] bytes = md.digest();

        // bytesToHex-method
        char[] hexChars = new char[bytes.length * 2];
        for ( int j = 0; j < bytes.length; j++ ) {
            int v = bytes[j] & 0xFF;
            hexChars[j * 2] = hexArray[v >>> 4];
            hexChars[j * 2 + 1] = hexArray[v & 0x0F];
        }

        return new String(hexChars);
}

I think you have to use the AJAX method instead which allows you to turn caching off:

$.ajax({
  url: "test.html",
  data: 'foo',
  success: function(){
    alert('bar');
  },
  cache: false
});

You can specify a Python version for pip to use:

pip3.4 install requests

Python 3.4 has pip support built-in, so you can also use:

python3.4 -m pip install

If you're running Ubuntu (or probably Debian as well), you'll need to install the system pip3 separately:

sudo apt-get install python3-pip

This will install the pip3 executable, so you can use it, as well as the earlier mentioned python3.4 -m pip:

pip3 install requests

Below function would work. You can copy from here and paste there...

-(void)savePhotoToAlbum:(UIImage*)imageToSave {

    CGImageRef imageRef = imageToSave.CGImage;
    NSDictionary *metadata = [NSDictionary new]; // you can add
    ALAssetsLibrary *library = [[ALAssetsLibrary alloc] init];

    [library writeImageToSavedPhotosAlbum:imageRef metadata:metadata completionBlock:^(NSURL *assetURL,NSError *error){
        if(error) {
            NSLog(@"Image save eror");
        }
    }];
}

I had the same problem but mine was Due To an Android database memory leak. I skipped a cursor. So the device crashes so as to fix that memory leak. If you are working with the Android database check if you skipped a cursor while retrieving from the database

The issue's coming from Jackson. When it doesn't have enough information on what class to deserialize to, it uses LinkedHashMap.

Since you're not informing Jackson of the element type of your ArrayList, it doesn't know that you want to deserialize into an ArrayList of Accounts. So it falls back to the default.

Instead, you could probably use as(JsonNode.class), and then deal with the ObjectMapper in a richer manner than rest-assured allows. Something like this:

ObjectMapper mapper = new ObjectMapper();

JsonNode accounts = given().when().expect().statusCode(expectedResponseCode)
    .get("accounts/" + newClub.getOwner().getCustId() + "/clubs")
    .as(JsonNode.class);


//Jackson's use of generics here are completely unsafe, but that's another issue
List<Account> accountList = mapper.convertValue(
    accounts, 
    new TypeReference<List<Account>>(){}
);

assertThat(accountList.get(0).getId()).isEqualTo(expectedId);

uint32_t is standard, uint32 is not. That is, if you include <inttypes.h> or <stdint.h>, you will get a definition of uint32_t. uint32 is a typedef in some local code base, but you should not expect it to exist unless you define it yourself. And defining it yourself is a bad idea.

Let me explain backwards:

Consider this...

foo()

... as syntactic sugar for:

foo.__call__()

Where foo can be any object that responds to __call__. When I say any object, I mean it: built-in types, your own classes and their instances.

In the case of built-in types, when you write:

int('10')
unicode(10)

You're essentially doing:

int.__call__('10')
unicode.__call__(10)

That's also why you don't have foo = new int in Python: you just make the class object return an instance of it on __call__. The way Python solves this is very elegant in my opinion.

You can declare SqlConnection and SqlCommand instances at global level so that you can use it through out the class. Connection string is in Web.Config.

SqlConnection sqlConn = new SqlConnection(WebConfigurationManager.ConnectionStrings["SqlConnector"].ConnectionString);
SqlCommand sqlcomm = new SqlCommand();

Now you can use the below method to pass values to Stored Procedure and get the DataSet.

public DataSet GetDataSet(string paramValue)
{
    sqlcomm.Connection = sqlConn;
    using (sqlConn)
    {
        try
        {
            using (SqlDataAdapter da = new SqlDataAdapter())
            {  
                // This will be your input parameter and its value
                sqlcomm.Parameters.AddWithValue("@ParameterName", paramValue);

                // You can retrieve values of `output` variables
                var returnParam = new SqlParameter
                {
                    ParameterName = "@Error",
                    Direction = ParameterDirection.Output,
                    Size = 1000
                };
                sqlcomm.Parameters.Add(returnParam);
                // Name of stored procedure
                sqlcomm.CommandText = "StoredProcedureName";
                da.SelectCommand = sqlcomm;
                da.SelectCommand.CommandType = CommandType.StoredProcedure;

                DataSet ds = new DataSet();
                da.Fill(ds);                            
            }
        }
        catch (SQLException ex)
        {
            Console.WriteLine("SQL Error: " + ex.Message);
        }
        catch (Exception e)
        {
            Console.WriteLine("Error: " + e.Message);
        }
    }
    return new DataSet();
}

The following is the sample of connection string in config file

<connectionStrings>
    <add name="SqlConnector"
         connectionString="data source=.\SQLEXPRESS;Integrated Security=SSPI;Initial Catalog=YourDatabaseName;User id=YourUserName;Password=YourPassword"
         providerName="System.Data.SqlClient" />
</connectionStrings>

You've not shown how you're creating the string 2016-01-12T23:00:00.000Z, but I assume via .format().

Anyway, .set() is using your local time zone, but the Z in the time string indicates zero time, otherwise known as UTC.

https://en.wikipedia.org/wiki/ISO_8601#Time_zone_designators

So I assume your local timezone is 23 hours from UTC?

saikumar's answer showed how to load the time in as UTC, but the other option is to use a .format() call that outputs using your local timezone, rather than UTC.

EXPOSE is used to map local port container port ie : if you specify expose in docker file like

EXPOSE 8090

What will does it will map localhost port 8090 to container port 8090

MySQL has drivers for many other languages, converting data to string "standardizes" data and leaves it up to the user to type-cast values to int or others

Simple:

if(pll_current_language() == 'en'){
   //do your work here
}

sum = sum.add(BigInteger.valueOf(i))

The BigInteger class is immutable, hence you can't change its state. So calling "add" creates a new BigInteger, rather than modifying the current.

As Karthik mentioned, dct.keys() will work but it will return all the keys in dict_keys type not in list type. So if you want all the keys in a list, then list(dct.keys()) will work.

Listen to window:scroll event for window/document level scrolling and element's scroll event for element level scrolling.

window:scroll

@HostListener('window:scroll', ['$event'])
onWindowScroll($event) {

}

or

<div (window:scroll)="onWindowScroll($event)">

scroll

@HostListener('scroll', ['$event'])
onElementScroll($event) {

}

or

<div (scroll)="onElementScroll($event)">

@HostListener('scroll', ['$event']) won't work if the host element itself is not scroll-able.

Examples

• Using Event Binding
• Using HostListener

try:

.table-hover > tbody > tr.active:hover > th {
                background-color: #color;
            }

So it turns out that if I add the Handler Mappings on the Website and Application level, everything works beautifully. I was only adding them on the server level, thus IIS did not know to map the asp pages to the IsapiModule.

So to resolve this issue, go to the website you want to add your application to, then double click on Handler Mappings. Click "Add Script Map" and enter in the following information:

RequestPath: *.asp
Executable: C:\Windows\System32\inetsrv\asp.dll
Name: Classic ASP (this can be anything you want it to be

        if(arr[i]==value) return i;
    return -1;

Make it lowercase first:

.m_title {text-transform: lowercase}

Then make it the first letter uppercase:

.m_title:first-letter {text-transform: uppercase}

"text-transform: capitalize" works for a word; but if you want to use for sentences this solution is perfect.

If you're using a scanner, in your scanner try to have it return the least number of qualifiers as possible. In fact, the qualifier(s) that you do return should be the smallest (in byte-size) as you have available. This will speed up your scan tremendously.

Unfortuneately this will only scale so far (millions-billions?). To take it further, you can do this in real time but you will first need to run a mapreduce job to count all rows.

Store the Mapreduce output in a cell in HBase. Every time you add a row, increment the counter by 1. Every time you delete a row, decrement the counter.

When you need to access the number of rows in real time, you read that field in HBase.

There is no fast way to count the rows otherwise in a way that scales. You can only count so fast.

You may find this thread useful. And here's a google code project exemplifying this (it P/Invokes into setupapi.dll).

req is an object containing information about the HTTP request that raised the event. In response to req, you use res to send back the desired HTTP response.

Those parameters can be named anything. You could change that code to this if it's more clear:

app.get('/user/:id', function(request, response){
  response.send('user ' + request.params.id);
});

Edit:

Say you have this method:

app.get('/people.json', function(request, response) { });

The request will be an object with properties like these (just to name a few):

• request.url, which will be "/people.json" when this particular action is triggered
• request.method, which will be "GET" in this case, hence the app.get() call.
• An array of HTTP headers in request.headers, containing items like request.headers.accept, which you can use to determine what kind of browser made the request, what sort of responses it can handle, whether or not it's able to understand HTTP compression, etc.
• An array of query string parameters if there were any, in request.query (e.g. /people.json?foo=bar would result in request.query.foo containing the string "bar").

To respond to that request, you use the response object to build your response. To expand on the people.json example:

app.get('/people.json', function(request, response) {
  // We want to set the content-type header so that the browser understands
  //  the content of the response.
  response.contentType('application/json');

  // Normally, the data is fetched from a database, but we can cheat:
  var people = [
    { name: 'Dave', location: 'Atlanta' },
    { name: 'Santa Claus', location: 'North Pole' },
    { name: 'Man in the Moon', location: 'The Moon' }
  ];

  // Since the request is for a JSON representation of the people, we
  //  should JSON serialize them. The built-in JSON.stringify() function
  //  does that.
  var peopleJSON = JSON.stringify(people);

  // Now, we can use the response object's send method to push that string
  //  of people JSON back to the browser in response to this request:
  response.send(peopleJSON);
});

For those of us trying to figure out how to hash our own classes whilst still using the standard template, there is a simple solution:

1. In your class you need to define an equality operator overload ==. If you don't know how to do this, GeeksforGeeks has a great tutorial https://www.geeksforgeeks.org/operator-overloading-c/

2. Under the standard namespace, declare a template struct called hash with your classname as the type (see below). I found a great blogpost that also shows an example of calculating hashes using XOR and bitshifting, but that's outside the scope of this question, but it also includes detailed instructions on how to accomplish using hash functions as well https://prateekvjoshi.com/2014/06/05/using-hash-function-in-c-for-user-defined-classes/

namespace std {

  template<>
  struct hash<my_type> {
    size_t operator()(const my_type& k) {
      // Do your hash function here
      ...
    }
  };

}

3. So then to implement a hashtable using your new hash function, you just have to create a std::map or std::unordered_map just like you would normally do and use my_type as the key, the standard library will automatically use the hash function you defined before (in step 2) to hash your keys.

#include <unordered_map>

int main() {
  std::unordered_map<my_type, other_type> my_map;
}

As a suggestion, you also can use the QChar::digitValue() to obtain the numeric value of the digit. For example:

for (int var = 0; var < myString.length(); ++var) {
    bool ok;
    if (myString.at(var).isDigit()){
        int digit = myString.at(var).digitValue();
        //DO SOMETHING HERE WITH THE DIGIT
    }
}

for (int i = 0; i < 5; i++){
    int asciiVal = rand()%26 + 97;
    char asciiChar = asciiVal;
    cout << asciiChar << " and ";
}

Here is an example of a parent List react component and whos props contain a react element. In this case, just a single Link react component is passed in (as seen in the dom render).

class Link extends React.Component {
  constructor(props){
    super(props);
  }
  render(){
    return (
      <div>
        <p>{this.props.name}</p>
      </div>
     );
  }
}
class List extends React.Component {
  render(){
   return(
    <div>
       {this.props.element}
       {this.props.element}
    </div>
   );
  }
}

ReactDOM.render(
  <List element = {<Link name = "working"/>}/>,
  document.getElementById('root')
);

As I see answers they're somehow old. Recently Google introduce DataBinding which is much easier to handle onClick or assigning in your xml.

Here is good example which you can see how to handle this :

<?xml version="1.0" encoding="utf-8"?>
<layout xmlns:android="http://schemas.android.com/apk/res/android">
   <data>
       <variable name="handlers" type="com.example.Handlers"/>
       <variable name="user" type="com.example.User"/>
   </data>
   <LinearLayout
       android:orientation="vertical"
       android:layout_width="match_parent"
       android:layout_height="match_parent">
       <TextView android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:text="@{user.firstName}"
           android:onClick="@{user.isFriend ? handlers.onClickFriend : handlers.onClickEnemy}"/>
       <TextView android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:text="@{user.lastName}"
           android:onClick="@{user.isFriend ? handlers.onClickFriend : handlers.onClickEnemy}"/>
   </LinearLayout>
</layout>

There is also very nice tutorial about DataBinding you can find it Here.

If only certain files need access to the modules in lib, just add a require statement to the files that need it. For example, if one model needs to access one module, add:

require 'mymodule'

at the top of the model.rb file.

If you just get rid of everything (e.g. if you are in tests)

org.apache.log4j.BasicConfigurator.configure(new NullAppender());

Suppose I have the following table T:

a   b
--------
1   abc
1   def
1   ghi
2   jkl
2   mno
2   pqr

And I do the following query:

SELECT a, b
FROM T
GROUP BY a

The output should have two rows, one row where a=1 and a second row where a=2.

But what should the value of b show on each of these two rows? There are three possibilities in each case, and nothing in the query makes it clear which value to choose for b in each group. It's ambiguous.

This demonstrates the single-value rule, which prohibits the undefined results you get when you run a GROUP BY query, and you include any columns in the select-list that are neither part of the grouping criteria, nor appear in aggregate functions (SUM, MIN, MAX, etc.).

Fixing it might look like this:

SELECT a, MAX(b) AS x
FROM T
GROUP BY a

Now it's clear that you want the following result:

a   x
--------
1   ghi
2   pqr

I posted my answer even though another answer has already been accepted; the accepted answer relies on a deprecated function; additionally, this deprecated function is based on Singular Value Decomposition (SVD), which (although perfectly valid) is the much more memory- and processor-intensive of the two general techniques for calculating PCA. This is particularly relevant here because of the size of the data array in the OP. Using covariance-based PCA, the array used in the computation flow is just 144 x 144, rather than 26424 x 144 (the dimensions of the original data array).

Here's a simple working implementation of PCA using the linalg module from SciPy. Because this implementation first calculates the covariance matrix, and then performs all subsequent calculations on this array, it uses far less memory than SVD-based PCA.

(the linalg module in NumPy can also be used with no change in the code below aside from the import statement, which would be from numpy import linalg as LA.)

The two key steps in this PCA implementation are:

• calculating the covariance matrix; and

• taking the eivenvectors & eigenvalues of this cov matrix

In the function below, the parameter dims_rescaled_data refers to the desired number of dimensions in the rescaled data matrix; this parameter has a default value of just two dimensions, but the code below isn't limited to two but it could be any value less than the column number of the original data array.

def PCA(data, dims_rescaled_data=2):
    """
    returns: data transformed in 2 dims/columns + regenerated original data
    pass in: data as 2D NumPy array
    """
    import numpy as NP
    from scipy import linalg as LA
    m, n = data.shape
    # mean center the data
    data -= data.mean(axis=0)
    # calculate the covariance matrix
    R = NP.cov(data, rowvar=False)
    # calculate eigenvectors & eigenvalues of the covariance matrix
    # use 'eigh' rather than 'eig' since R is symmetric, 
    # the performance gain is substantial
    evals, evecs = LA.eigh(R)
    # sort eigenvalue in decreasing order
    idx = NP.argsort(evals)[::-1]
    evecs = evecs[:,idx]
    # sort eigenvectors according to same index
    evals = evals[idx]
    # select the first n eigenvectors (n is desired dimension
    # of rescaled data array, or dims_rescaled_data)
    evecs = evecs[:, :dims_rescaled_data]
    # carry out the transformation on the data using eigenvectors
    # and return the re-scaled data, eigenvalues, and eigenvectors
    return NP.dot(evecs.T, data.T).T, evals, evecs

def test_PCA(data, dims_rescaled_data=2):
    '''
    test by attempting to recover original data array from
    the eigenvectors of its covariance matrix & comparing that
    'recovered' array with the original data
    '''
    _ , _ , eigenvectors = PCA(data, dim_rescaled_data=2)
    data_recovered = NP.dot(eigenvectors, m).T
    data_recovered += data_recovered.mean(axis=0)
    assert NP.allclose(data, data_recovered)


def plot_pca(data):
    from matplotlib import pyplot as MPL
    clr1 =  '#2026B2'
    fig = MPL.figure()
    ax1 = fig.add_subplot(111)
    data_resc, data_orig = PCA(data)
    ax1.plot(data_resc[:, 0], data_resc[:, 1], '.', mfc=clr1, mec=clr1)
    MPL.show()

>>> # iris, probably the most widely used reference data set in ML
>>> df = "~/iris.csv"
>>> data = NP.loadtxt(df, delimiter=',')
>>> # remove class labels
>>> data = data[:,:-1]
>>> plot_pca(data)

The plot below is a visual representation of this PCA function on the iris data. As you can see, a 2D transformation cleanly separates class I from class II and class III (but not class II from class III, which in fact requires another dimension).

Looks like a bug in VS code's OmniSharp.

Solution for me was to execute command "Restart OmniSharp".

Just do: - ctr shift P - type "Restart OmniSharp" .. hit enter

This fixed it for me.

You could use built-in function trigger_error() to trigger user errors/warnings/notices and set_error_handler() to handle them. Inside your error handler you might want to use error_log() or file_put_contents() to store all records on files. To have a single file for every day just use something like sprintf('%s.log', date('Y-m-d')) as filename. And now you should know where to start... :)

Send it as raw data and set the type to application/json

I guess this is essentially putting it in a string, but this avoids the rounding error:

import decimal

def display(x):
    digits = 15
    temp = str(decimal.Decimal(str(x) + '0' * digits))
    return temp[:temp.find('.') + digits + 1]

Lines 1,2,3,4 will call the default constructor. They are different in the essence as 1,2 are dynamically created object and 3,4 are statically created objects.

In Line 7, you create an object inside the argument call. So its an error.

And Lines 5 and 6 are invitation for memory leak.

You can change the highlight color in several ways.

1. Change the selectionStyle property of your cell. If you change it to UITableViewCellSelectionStyleGray, it will be gray.

2. Change the selectedBackgroundView property. Actually what creates the blue gradient is a view. You can create a view and draw what ever you like, and use the view as the background of your table view cells.

I'm in a particular situation where I do not have permissions to turn logging on, and wouldn't have permissions to see the logs if they were turned on. I could not add a trigger, but I did have permissions to call show processlist. So, I gave it a best effort and came up with this:

Create a bash script called "showsqlprocesslist":

#!/bin/bash

while [ 1 -le 1 ]
do
         mysql --port=**** --protocol=tcp --password=**** --user=**** --host=**** -e "show processlist\G" | grep Info | grep -v processlist | grep -v "Info: NULL";
done

Execute the script:

./showsqlprocesslist > showsqlprocesslist.out &

Tail the output:

tail -f showsqlprocesslist.out

Bingo bango. Even though it's not throttled, it only took up 2-4% CPU on the boxes I ran it on. I hope maybe this helps someone.

You can use static variables fairly easily as long as they are thread-local.

The downside is that the object will not be visible to other threads your program might spawn. The upside is that unlike truly global state, it is entirely safe and is not a pain to use - true global state is a massive pain in any language. Here's an example:

extern mod sqlite;

use std::cell::RefCell;

thread_local!(static ODB: RefCell<sqlite::database::Database> = RefCell::new(sqlite::open("test.db"));

fn main() {
    ODB.with(|odb_cell| {
        let odb = odb_cell.borrow_mut();
        // code that uses odb goes here
    });
}

Here we create a thread-local static variable and then use it in a function. Note that it is static and immutable; this means that the address at which it resides is immutable, but thanks to RefCell the value itself will be mutable.

Unlike regular static, in thread-local!(static ...) you can create pretty much arbitrary objects, including those that require heap allocations for initialization such as Vec, HashMap and others.

If you cannot initialize the value right away, e.g. it depends on user input, you may also have to throw Option in there, in which case accessing it gets a bit unwieldy:

extern mod sqlite;

use std::cell::RefCell;

thread_local!(static ODB: RefCell<Option<sqlite::database::Database>> = RefCell::New(None));

fn main() {
    ODB.with(|odb_cell| {
        // assumes the value has already been initialized, panics otherwise
        let odb = odb_cell.borrow_mut().as_mut().unwrap();
        // code that uses odb goes here
    });
}

Not sure if that might really help you but that's how caching should work on any browser. When the browser request a file, it should always send a request to the server unless there is a "offline" mode. The server will read some parameters like date modified or etags.

The server will return a 304 error response for NOT MODIFIED and the browser will have to use its cache. If the etag doesn't validate on server side or the modified date is below the current modified date, the server should return the new content with the new modified date or etags or both.

If there is no caching data sent to the browser, I guess the behavior is undetermined, the browser may or may not cache file that don't tell how they are cached. If you set caching parameters in the response it will cache your files correctly and the server then may choose to return a 304 error, or the new content.

This is how it should be done. Using random params or version number in urls is more like a hack than anything.

http://www.checkupdown.com/status/E304.html http://en.wikipedia.org/wiki/HTTP_ETag http://www.xpertdeveloper.com/2011/03/last-modified-header-vs-expire-header-vs-etag/

After reading I saw that there is also a expire date. If you have problem, it might be that you have a expire date set up. In other words, when the browser will cache your file, since it has a expiry date, it shouldn't have to request it again before that date. In other words, it will never ask the file to the server and will never receive a 304 not modified. It will simply use the cache until the expiry date is reached or cache is cleared.

So that is my guess, you have some sort of expiry date and you should use last-modified etags or a mix of it all and make sure that there is no expire date.

If people tends to refresh a lot and the file doesn't get changed a lot, then it might be wise to set a big expiry date.

My 2 cents!

I'll Explain how to add an image using Android studio(2.3.3). First you need to add the image into res/drawable folder in the project. Like below

Now in go to activity_main.xml (or any activity you need to add image) and select the Design view. There you can see your Palette tool box on left side. You need to drag and drop ImageView.

It will prompt you Resources dialog box. In there select Drawable under the project section you can see your image. Like below

Select the image you want press Ok you can see the image on the Design view. If you want it configure using xml it would look like below.

<ImageView
        android:id="@+id/imageView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        app:srcCompat="@drawable/homepage"
        tools:layout_editor_absoluteX="55dp"
        tools:layout_editor_absoluteY="130dp" />

You need to give image location using

app:srcCompat="@drawable/imagename"

Add android:fitsSystemWindows="true" to the layout, and this layout will resize.

just enter the following command on command prompt after launching the app:

adb shell dumpsys window windows | find "mCurrentFocus"

if executing the command on linux terminal replace find by grep

This should do what you need.

var enumType = typeof(FunkyAttributesEnum);
var memberInfos = enumType.GetMember(FunkyAttributesEnum.NameWithoutSpaces1.ToString());

      enumValueMemberInfo.GetCustomAttributes(typeof(DescriptionAttribute), false);
var description = ((DescriptionAttribute)valueAttributes[0]).Description;

just right click on the project file in eclipse and in build path select "Use as source folder"...It worked for me

I applied CSS styling to an anchored HREF attribute fully emulating the push button behaviors I needed (hover, active, background-color, etc., etc.). HTML markup is much simpler a-n-d eliminates the get/post complexity associated with using a form-based approach.

No.

Equality is equality.

The function you wrote will not test two doubles for equality, as its name promises. It will only test if two doubles are "close enough" to each other.

If you really want to test two doubles for equality, use this one:

inline bool isEqual(double x, double y)
{
   return x == y;
}

Coding standards usually recommend against comparing two doubles for exact equality. But that is a different subject. If you actually want to compare two doubles for exact equality, x == y is the code you want.

10.000000000000001 is not equal to 10.0, no matter what they tell you.

An example of using exact equality is when a particular value of a double is used as a synonym of some special state, such as "pending calulation" or "no data available". This is possible only if the actual numeric values after that pending calculation are only a subset of the possible values of a double. The most typical particular case is when that value is nonnegative, and you use -1.0 as an (exact) representation of a "pending calculation" or "no data available". You could represent that with a constant:

const double NO_DATA = -1.0;

double myData = getSomeDataWhichIsAlwaysNonNegative(someParameters);

if (myData != NO_DATA)
{
    ...
}

Note as of react-native 0.60.x you can use the following to regenerate ios/android directories:

react-native upgrade --legacy true

Credit here: https://github.com/facebook/react-native/issues/25526

Note that you can build your own cross-platform library in python using conditional imports. e.g.

import platform
if platform.system() == 'Linux':
  import LinuxMac
  mac_address = LinuxMac.get_mac_address()
elif platform.system() == 'Windows':
  # etc

This will allow you to use os.system calls or platform-specific libraries.

You do not need to use docker run.

You can do it with docker create.

From the docs:

The docker create command creates a writeable container layer over the specified image and prepares it for running the specified command. The container ID is then printed to STDOUT. This is similar to docker run -d except the container is never started.

So, you can do:

docker create -ti --name dummy IMAGE_NAME bash
docker cp dummy:/path/to/file /dest/to/file
docker rm -f dummy

Here, you never start the container. That looked beneficial to me.

hmm, break ?

Try like this

Pass Camera Intent like below

Intent intent = new Intent(this);
startActivityForResult(intent, REQ_CAMERA_IMAGE);

And after capturing image Write an OnActivityResult as below

protected void onActivityResult(int requestCode, int resultCode, Intent data) {  
    if (requestCode == CAMERA_REQUEST && resultCode == RESULT_OK) {
        Bitmap photo = (Bitmap) data.getExtras().get("data"); 
        imageView.setImageBitmap(photo);
        knop.setVisibility(Button.VISIBLE);


        // CALL THIS METHOD TO GET THE URI FROM THE BITMAP
        Uri tempUri = getImageUri(getApplicationContext(), photo);

        // CALL THIS METHOD TO GET THE ACTUAL PATH
        File finalFile = new File(getRealPathFromURI(tempUri));

        System.out.println(mImageCaptureUri);
    }  
}

public Uri getImageUri(Context inContext, Bitmap inImage) {
    ByteArrayOutputStream bytes = new ByteArrayOutputStream();
    inImage.compress(Bitmap.CompressFormat.JPEG, 100, bytes);
    String path = Images.Media.insertImage(inContext.getContentResolver(), inImage, "Title", null);
    return Uri.parse(path);
}

public String getRealPathFromURI(Uri uri) {
    String path = "";
    if (getContentResolver() != null) {
        Cursor cursor = getContentResolver().query(uri, null, null, null, null);
        if (cursor != null) {
            cursor.moveToFirst();
            int idx = cursor.getColumnIndex(MediaStore.Images.ImageColumns.DATA);
            path = cursor.getString(idx);
            cursor.close();
        }
    }
    return path;
}

And check log

Edit:

Lots of people are asking how to not get a thumbnail. You need to add this code instead for the getImageUri method:

public Uri getImageUri(Context inContext, Bitmap inImage) {
    Bitmap OutImage = Bitmap.createScaledBitmap(inImage, 1000, 1000,true);
    String path = MediaStore.Images.Media.insertImage(inContext.getContentResolver(), OutImage, "Title", null);
    return Uri.parse(path);
}

The other method Compresses the file. You can adjust the size by changing the number 1000,1000

The best way to do this in Angular and keep the code simple is to use this project.

https://www.npmjs.com/package/ngx-clipboard

    <fa-icon icon="copy" ngbTooltip="Copy to Clipboard" aria-hidden="true" 
    ngxClipboard [cbContent]="target value here" 
    (cbOnSuccess)="copied($event)"></fa-icon>

From command prompt Run as Administrator. Example below is to print a list of Services running on your PC run the command below:

net start > c:\netstart.txt

You should see a copy of the text file you just exported with a listing all the PC services running at the root of your C:\ drive.

I'm wondering whether you meant "recursive". Here is a simple example of a recursive function to compute the factorial function:

def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n - 1)

The two key elements of a recursive algorithm are:

• The termination condition: n == 0
• The reduction step where the function calls itself with a smaller number each time: factorial(n - 1)

1. clang has advantages in error reporting & recovery.

   $ clang errors.c
   errors.c:36:21: warning: result of comparison against a string literal is unspecified (use strcmp instead)
           if (args[i] == "&") //WARNING HERE
                       ^~ ~~~
               strcmp( ,     ) == 0
   errors.c:38:26: warning: result of comparison against a string literal is unspecified (use strcmp instead)
           else if (args[i] == "<") //WARNING HERE

                    strcmp( ,     ) == 0
   errors.c:44:26: warning: result of comparison against a string literal is unspecified (use strcmp instead)
           else if (args[i] == ">") //WARNING HERE
                            ^~ ~~~
                    strcmp( ,     ) == 0
   

   It suggests to replace x == y by strcmp(x,y) == 0.

2. gengetopt writes command-line option parser for you.

To get the image URL, NOT binary content:

$url = "http://graph.facebook.com/$fbId/picture?type=$size";

$headers = get_headers($url, 1);

if( isset($headers['Location']) )
    echo $headers['Location']; // string
else
    echo "ERROR";

You must use your FACEBOOK ID, NOT USERNAME. You can get your facebook id there:

http://findmyfbid.com/

Write bytes and Create the file if not exists:

f = open('./put/your/path/here.png', 'wb')
f.write(data)
f.close()

wb means open the file in write binary mode.

For anyone still looking for a simpler method to transfer repos from Gitlab to Github while preserving all history.

Step 1. Login to Github, create a private repo with the exact same name as the repo you would like to transfer.

Step 2. Under "push an existing repository from the command" copy the link of the new repo, it will look something like this:

[email protected]:your-name/name-of-repo.git

Step 3. Open up your local project and look for the folder .git typically this will be a hidden folder. Inside the .git folder open up config.

The config file will contain something like:

[remote "origin"]
url = [email protected]:your-name/name-of-repo.git
fetch = +refs/heads/:refs/remotes/origin/

Under [remote "origin"], change the URL to the one that you copied on Github.

Step 4. Open your project folder in the terminal and run: git push --all. This will push your code to Github as well as all the commit history.

Step 5. To make sure everything is working as expected, make changes, commit, push and new commits should appear on the newly created Github repo.

Step 6. As a last step, you can now archive your Gitlab repo or set it to read only.

I still found that with the solutions above, it didn't work (for example) with the Rails plugin for TextMate. I got a similar error (when retrieving the database schema).

So what did is, open terminal:

cd /usr/local/lib
sudo ln -s ../mysql-5.5.8-osx10.6-x86_64/lib/libmysqlclient.16.dylib .

Replace mysql-5.5.8-osx10.6-x86_64 with your own path (or mysql).

This makes a symbol link to the lib, now rails runs from the command line, as-well as TextMate plugin(s) like ruby-on-rails-tmbundle.

To be clear: this also fixes the error you get when starting rails server.

I know it's way too late to answer this question, but I'll just post the solution that worked for me, in case someone runs into trouble again in the future.

I tried using genymotion's own adb tools and the original Android SDK ones, and even purging and reinstalling adb from my system, but nothing worked. I kept getting the error:

adb server is out of date. killing... cannot bind 'tcp:5037' ADB server didn't ACK *failed to start daemon* error:
So I tried adb connect [ip] as suggested here, but I didn't work either, the same error came up.

What finally worked for me was downloading ADT, and running adb directly from the downloaded folder, instead of the system-wide command. So adb devices will give me the error above, but /yourdownloadpath/adb devices works just fine for me.

Hope it helped.

run in root access ssh chould solve this problem

or chmod 0777 /dir/to/be/backedup/

or chown username:user /dir/to/be/backedup/

Have you tried this?

$(document).ajaxError(function(){ alert('error'); }

That should handle all AjaxErrors. I´ve found it here. There you find also a possibility to write these errors to your firebug console.

In general, I break lines before operators, and indent the subsequent lines:

Map<long parameterization> longMap
    = new HashMap<ditto>();

String longString = "some long text"
                  + " some more long text";

To me, the leading operator clearly conveys that "this line was continued from something else, it doesn't stand on its own." Other people, of course, have different preferences.

For multiple datetime columns with no header, and a lot of columns, say my datetime fields are in columns 36 and 38, and I want them read in as character fields:

data<-read.csv("test.csv", head=FALSE,   colClasses=c("V36"="character","V38"="character"))                        

For your case it was right/beautiful if you would use the "decorator" or "date model transformation" patterns. For example:

Your model

class Car {
    /** @var int */
    private $color;

    /** @var string */
    private $model;

    /** @var string */
    private $type;

    /**
     * @return int
     */
    public function getColor(): int
    {
        return $this->color;
    }

    /**
     * @param int $color
     * @return Car
     */
    public function setColor(int $color): Car
    {
        $this->color = $color;
        return $this;
    }

    /**
     * @return string
     */
    public function getModel(): string
    {
        return $this->model;
    }

    /**
     * @param string $model
     * @return Car
     */
    public function setModel(string $model): Car
    {
        $this->model = $model;

        return $this;
    }

    /**
     * @return string
     */
    public function getType(): string
    {
        return $this->type;
    }

    /**
     * @param string $type
     * @return Car
     */
    public function setType(string $type): Car
    {
        $this->type = $type;

        return $this;
    }
}

Decorator

class CarArrayDecorator
{
    /** @var Car */
    private $car;

    /**
     * CarArrayDecorator constructor.
     * @param Car $car
     */
    public function __construct(Car $car)
    {
        $this->car = $car;
    }

    /**
     * @return array
     */
    public function getArray(): array
    {
        return [
            'color' => $this->car->getColor(),
            'type' => $this->car->getType(),
            'model' => $this->car->getModel(),
        ];
    }
}

Usage

$car = new Car();
$car->setType('type#');
$car->setModel('model#1');
$car->setColor(255);

$carDecorator = new CarArrayDecorator($car);
$carResponseData = $carDecorator->getArray();

So it will be more beautiful and more correct code.

For me save_queries option was turned off so,

$this->db->save_queries = TRUE; //Turn ON save_queries for temporary use.
$str = $this->db->last_query();
echo $str;

Ref: Can't get result from $this->db->last_query(); codeigniter

You have no valid main method... The signature should be: public static void main(String[] args);

Hence, in your case the code should look like this:

public class Echo {
    public static void main (String[] arg) {

            System.out.println(arg[0]);
    }
}

Edit: Please note that Oscar is also right in that you are missing . in your classpath, you would run into the problem I solve after you have dealt with that error.

On Debian/Ubuntu:

aptitude install python-numpy

On Windows, download the installer:

http://sourceforge.net/projects/numpy/files/NumPy/

On other systems, download the tar.gz and run the following:

$ tar xfz numpy-n.m.tar.gz
$ cd numpy-n.m
$ python setup.py install

One possible solution is:

<h:panelGroup rendered="#{bean.row == 10}">
    <div class="text-success">
        <h:outputText value="#{bean.row}"/>
    </div>
</h:panelGroup>

Maybe I am missing something (lots of many-upvotes-members answers here that seem to be looking at this different to I, which would seem implausible that I am correct), but length is not the correct terminology for counting something. Length is usually used to obtain what you are getting, and not what you are wanting.

$cars.count should give you what you seem to be looking for.

SELECT  name, LENGTH(name) AS mlen
FROM    mytable
ORDER BY
        mlen DESC
LIMIT 1

I create a common init for the designated and required. For convenience inits I delegate to init(frame:) with frame of zero.

Having zero frame is not a problem because typically the view is inside a ViewController's view; your custom view will get a good, safe chance to layout its subviews when its superview calls layoutSubviews() or updateConstraints(). These two functions are called by the system recursively throughout the view hierarchy. You can use either updateContstraints() or layoutSubviews(). updateContstraints() is called first, then layoutSubviews(). In updateConstraints() make sure to call super last. In layoutSubviews(), call super first.

Here's what I do:

@IBDesignable
class MyView: UIView {

      convenience init(args: Whatever) {
          self.init(frame: CGRect.zero)
          //assign custom vars
      }

      override init(frame: CGRect) {
           super.init(frame: frame)
           commonInit()
      }

      required init?(coder aDecoder: NSCoder) {
           super.init(coder: aDecoder)
           commonInit()
      }

      override func prepareForInterfaceBuilder() {
           super.prepareForInterfaceBuilder()
           commonInit()
      }

      private func commonInit() {
           //custom initialization
      }

      override func updateConstraints() {
           //set subview constraints here
           super.updateConstraints()
      }

      override func layoutSubviews() {
           super.layoutSubviews()
           //manually set subview frames here
      }

}

You could simply get the character length of the current directory, and remove them from your absolute list

setlocal EnableDelayedExpansion
for /L %%n in (1 1 500) do if "!__cd__:~%%n,1!" neq "" set /a "len=%%n+1"
setlocal DisableDelayedExpansion
for /r . %%g in (*.log) do (
  set "absPath=%%g"
  setlocal EnableDelayedExpansion
  set "relPath=!absPath:~%len%!"
  echo(!relPath!
  endlocal
)

You could also use the store library which performs it for you with crossbrowser ability.

example :

// Store current user
store.set('user', { name:'Marcus' })

// Get current user
store.get('user')

// Remove current user
store.remove('user')

// Clear all keys
store.clearAll()

// Loop over all stored values
store.each(function(value, key) {
    console.log(key, '==', value)
})

If you want give some default value to a parameter assign value in (). like (x =10). But important is first should compulsory argument then default value.

eg.

(y, x =10)

but

(x=10, y) is wrong

There are a few options...

1. Override the push method

Object.defineProperty(myArray, "push", {
  enumerable: false, // hide from for...in
  configurable: false, // prevent further meddling...
  writable: false, // see above ^
  value: function () {
    for (var i = 0, n = this.length, l = arguments.length; i < l; i++, n++) {          
      RaiseMyEvent(this, n, this[n] = arguments[i]); // assign/raise your event
    }
    return n;
  }
});

_{¹ Alternatively, if you'd like to target all arrays, you could override Array.prototype.push(). Use caution, though; other code in your environment may not like or expect that kind of modification. Still, if a catch-all sounds appealing, just replace myArray with Array.prototype.}

Now, that's just one method and there are lots of ways to change array content. We probably need something more comprehensive...

2. Create a custom observable array

function ObservableArray(items) {
  var _self = this,
    _array = [],
    _handlers = {
      itemadded: [],

That gets us closer but it's still not bullet proof... which brings us to:

3. Proxies

A Proxy object offers another solution to the modern browser. It allows you to intercept method calls, accessors, etc. Most importantly, you can do this without even providing an explicit property name... which would allow you to test for an arbitrary, index-based access/assignment. You can even intercept property deletion. Proxies would effectively allow you to inspect a change before deciding to allow it... in addition to handling the change after the fact.

Here's a stripped down sample:

(function() {

  if (!("Proxy" in window)) {
    console.warn("Your browser doesn't support Proxies.");
    return;
  }

  // our backing array
  var array = ["a", "b", "c", "d"];

  // a proxy for our array
  var proxy = new Proxy(array, {
    apply: function(target, thisArg, argumentsList) {
      return thisArg[target].apply(this, argumentList);
    },
    deleteProperty: function(target, property) {
      console.log("Deleted %s", property);
      return true;
    },
    set: function(target, property, value, receiver) {      
      target[property] = value;
      console.log("Set %s to %o", property, value);
      return true;
    }
  });

  console.log("Set a specific index..");
  proxy[0] = "x";

  console.log("Add via push()...");
  proxy.push("z");

  console.log("Add/remove via splice()...");
  proxy.splice(1, 3, "y");

  console.log("Current state of array: %o", array);

})();

In the case you want to format it within a formula (for example, if you are concatenating strings and values), the aforementioned format option of Google is not available, but you can use the TEXT formula:

=TEXT(B1-C1,"HH:MM:SS")

Therefore, for the questioned example, with concatenation:

="The number of " & TEXT(B1,"HH") & " hour slots in " & TEXT(C1,"HH") _
& " is " & TEXT(C1/B1,"HH")

Cheers

First, you should note that mixins only exist in multiple-inheritance languages. You can't do a mixin in Java or C#.

Basically, a mixin is a stand-alone base type that provides limited functionality and polymorphic resonance for a child class. If you're thinking in C#, think of an interface that you don't have to actually implement because it's already implemented; you just inherit from it and benefit from its functionality.

Mixins are typically narrow in scope and not meant to be extended.

[edit -- as to why:]

I suppose I should address why, since you asked. The big benefit is that you don't have to do it yourself over and over again. In C#, the biggest place where a mixin could benefit might be from the Disposal pattern. Whenever you implement IDisposable, you almost always want to follow the same pattern, but you end up writing and re-writing the same basic code with minor variations. If there were an extendable Disposal mixin, you could save yourself a lot of extra typing.

[edit 2 -- to answer your other questions]

What separates a mixin from multiple inheritance? Is it just a matter of semantics?

Yes. The difference between a mixin and standard multiple inheritance is just a matter of semantics; a class that has multiple inheritance might utilize a mixin as part of that multiple inheritance.

The point of a mixin is to create a type that can be "mixed in" to any other type via inheritance without affecting the inheriting type while still offering some beneficial functionality for that type.

Again, think of an interface that is already implemented.

I personally don't use mixins since I develop primarily in a language that doesn't support them, so I'm having a really difficult time coming up with a decent example that will just supply that "ahah!" moment for you. But I'll try again. I'm going to use an example that's contrived -- most languages already provide the feature in some way or another -- but that will, hopefully, explain how mixins are supposed to be created and used. Here goes:

Suppose you have a type that you want to be able to serialize to and from XML. You want the type to provide a "ToXML" method that returns a string containing an XML fragment with the data values of the type, and a "FromXML" that allows the type to reconstruct its data values from an XML fragment in a string. Again, this is a contrived example, so perhaps you use a file stream, or an XML Writer class from your language's runtime library... whatever. The point is that you want to serialize your object to XML and get a new object back from XML.

The other important point in this example is that you want to do this in a generic way. You don't want to have to implement a "ToXML" and "FromXML" method for every type that you want to serialize, you want some generic means of ensuring that your type will do this and it just works. You want code reuse.

If your language supported it, you could create the XmlSerializable mixin to do your work for you. This type would implement the ToXML and the FromXML methods. It would, using some mechanism that's not important to the example, be capable of gathering all the necessary data from any type that it's mixed in with to build the XML fragment returned by ToXML and it would be equally capable of restoring that data when FromXML is called.

And.. that's it. To use it, you would have any type that needs to be serialized to XML inherit from XmlSerializable. Whenever you needed to serialize or deserialize that type, you would simply call ToXML or FromXML. In fact, since XmlSerializable is a fully-fledged type and polymorphic, you could conceivably build a document serializer that doesn't know anything about your original type, accepting only, say, an array of XmlSerializable types.

Now imagine using this scenario for other things, like creating a mixin that ensures that every class that mixes it in logs every method call, or a mixin that provides transactionality to the type that mixes it in. The list can go on and on.

If you just think of a mixin as a small base type designed to add a small amount of functionality to a type without otherwise affecting that type, then you're golden.

Hopefully. :)

1. Select a database with identifier mysql_select_db("form1",$connect);

2. Are you getting syntax error? If please put a ; next to $comment = $rows['Comment'].

3. Also the variables should be case sensitive here

you can use str_replace say your name is in variable $name

$result = str_replace(' ', '_', $name);

another way is to use regex, as it will help to eliminate 2-time space etc.

  $result=  preg_replace('/\s+/', '_', $name);

First, the right place to mess with rendering are directives. My advice would be to wrap DOM manipulating jQuery plugins by directives like this one.

I had the same problem and came up with this snippet. It uses $watch and $evalAsync to ensure your code runs after directives like ng-repeat have been resolved and templates like {{ value }} got rendered.

app.directive('name', function() {
    return {
        link: function($scope, element, attrs) {
            // Trigger when number of children changes,
            // including by directives like ng-repeat
            var watch = $scope.$watch(function() {
                return element.children().length;
            }, function() {
                // Wait for templates to render
                $scope.$evalAsync(function() {
                    // Finally, directives are evaluated
                    // and templates are renderer here
                    var children = element.children();
                    console.log(children);
                });
            });
        },
    };
});

Hope this can help you prevent some struggle.

You can also do this in addition

import re
string='24234ww'
val = re.search('[a-zA-Z]+',string) 
val[0].isalpha() # returns True if the variable is an alphabet
print(val[0]) # this will print the first instance of the matching value

Also note that if variable val returns None. That means the search did not find a match

You can do:

$("#country.save")...

OR

$("a#country.save")...

OR

$("a.save#country")...

as you prefer.

So yes you can specify a selector that has to match ID and class (and potentially tag name and anything else you want to throw in).

Note that this answer is outdated! The mysql extension is no longer available out of the box as of PHP7. If you want to use the old mysql functions in PHP7, you will have to compile ext/mysql from PECL. See the other answers for more current solutions.

This would work, see more documentation here : http://php.net/manual/en/function.mysql-fetch-array.php

$result = mysql_query("SELECT names FROM Customers");
$storeArray = Array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC)) {
    $storeArray[] =  $row['names'];  
}
// now $storeArray will have all the names.

If you cannot use TRUNCATE (e.g. because of foreign key constraints) you can use an alter table after deleting all rows to restart the auto_increment:

ALTER TABLE mytable AUTO_INCREMENT = 1

Some times there are problems with funtion/features that do not interact with the DOM

try to change the value sharply and then assign the $scope

document.getElementById ("textWidget") value = "<NewVal>";
$scope.widget.title = "<NewVal>";

why not use flexbox ? so wrap them into another div like that

.flexContainer { _x000D_
   _x000D_
  margin: 2px 10px;_x000D_
  display: flex;_x000D_
} _x000D_
_x000D_
.left {_x000D_
  flex-basis : 30%;_x000D_
}_x000D_
_x000D_
.right {_x000D_
  flex-basis : 30%;_x000D_
}

<form id="new_production" class="simple_form new_production" novalidate="novalidate" method="post" action="/projects/1/productions" accept-charset="UTF-8">_x000D_
    <div style="margin:0;padding:0;display:inline">_x000D_
        <input type="hidden" value="?" name="utf8">_x000D_
        <input type="hidden" value="2UQCUU+tKiKKtEiDtLLNeDrfBDoHTUmz5Sl9+JRVjALat3hFM=" name="authenticity_token">_x000D_
    </div>_x000D_
    <div class="flexContainer">_x000D_
      <div class="left">Proj Name:</div>_x000D_
      <div class="right">must have a name</div>_x000D_
    </div>_x000D_
    <div class="input string required"> </div>_x000D_
 </form>

feel free to play with flex-basis percentage to get more customized space.

std::chrono::time_point<std::chrono::system_clock> now = std::chrono::system_clock::now();

This is a great place for auto:

auto now = std::chrono::system_clock::now();

Since you want to traffic at millisecond precision, it would be good to go ahead and covert to it in the time_point:

auto now_ms = std::chrono::time_point_cast<std::chrono::milliseconds>(now);

now_ms is a time_point, based on system_clock, but with the precision of milliseconds instead of whatever precision your system_clock has.

auto epoch = now_ms.time_since_epoch();

epoch now has type std::chrono::milliseconds. And this next statement becomes essentially a no-op (simply makes a copy and does not make a conversion):

auto value = std::chrono::duration_cast<std::chrono::milliseconds>(epoch);

Here:

long duration = value.count();

In both your and my code, duration holds the number of milliseconds since the epoch of system_clock.

This:

std::chrono::duration<long> dur(duration);

Creates a duration represented with a long, and a precision of seconds. This effectively reinterpret_casts the milliseconds held in value to seconds. It is a logic error. The correct code would look like:

std::chrono::milliseconds dur(duration);

This line:

std::chrono::time_point<std::chrono::system_clock> dt(dur);

creates a time_point based on system_clock, with the capability of holding a precision to the system_clock's native precision (typically finer than milliseconds). However the run-time value will correctly reflect that an integral number of milliseconds are held (assuming my correction on the type of dur).

Even with the correction, this test will (nearly always) fail though:

if (dt != now)

Because dt holds an integral number of milliseconds, but now holds an integral number of ticks finer than a millisecond (e.g. microseconds or nanoseconds). Thus only on the rare chance that system_clock::now() returned an integral number of milliseconds would the test pass.

But you can instead:

if (dt != now_ms)

And you will now get your expected result reliably.

Putting it all together:

int main ()
{
    auto now = std::chrono::system_clock::now();
    auto now_ms = std::chrono::time_point_cast<std::chrono::milliseconds>(now);

    auto value = now_ms.time_since_epoch();
    long duration = value.count();

    std::chrono::milliseconds dur(duration);

    std::chrono::time_point<std::chrono::system_clock> dt(dur);

    if (dt != now_ms)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

Personally I find all the std::chrono overly verbose and so I would code it as:

int main ()
{
    using namespace std::chrono;
    auto now = system_clock::now();
    auto now_ms = time_point_cast<milliseconds>(now);

    auto value = now_ms.time_since_epoch();
    long duration = value.count();

    milliseconds dur(duration);

    time_point<system_clock> dt(dur);

    if (dt != now_ms)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

Which will reliably output:

Success.

Finally, I recommend eliminating temporaries to reduce the code converting between time_point and integral type to a minimum. These conversions are dangerous, and so the less code you write manipulating the bare integral type the better:

int main ()
{
    using namespace std::chrono;
    // Get current time with precision of milliseconds
    auto now = time_point_cast<milliseconds>(system_clock::now());
    // sys_milliseconds is type time_point<system_clock, milliseconds>
    using sys_milliseconds = decltype(now);
    // Convert time_point to signed integral type
    auto integral_duration = now.time_since_epoch().count();
    // Convert signed integral type to time_point
    sys_milliseconds dt{milliseconds{integral_duration}};
    // test
    if (dt != now)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

The main danger above is not interpreting integral_duration as milliseconds on the way back to a time_point. One possible way to mitigate that risk is to write:

    sys_milliseconds dt{sys_milliseconds::duration{integral_duration}};

This reduces risk down to just making sure you use sys_milliseconds on the way out, and in the two places on the way back in.

And one more example: Let's say you want to convert to and from an integral which represents whatever duration system_clock supports (microseconds, 10^th of microseconds or nanoseconds). Then you don't have to worry about specifying milliseconds as above. The code simplifies to:

int main ()
{
    using namespace std::chrono;
    // Get current time with native precision
    auto now = system_clock::now();
    // Convert time_point to signed integral type
    auto integral_duration = now.time_since_epoch().count();
    // Convert signed integral type to time_point
    system_clock::time_point dt{system_clock::duration{integral_duration}};
    // test
    if (dt != now)
        std::cout << "Failure." << std::endl;
    else
        std::cout << "Success." << std::endl;
}

This works, but if you run half the conversion (out to integral) on one platform and the other half (in from integral) on another platform, you run the risk that system_clock::duration will have different precisions for the two conversions.

I had the same problem but got round it by setting AutoPostBack to true and in an update panel set the trigger to the dropdownlist control id and event name to SelectedIndexChanged e.g.

    <asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Always" enableViewState="true">
        <Triggers>
            <asp:AsyncPostBackTrigger ControlID="ddl1" EventName="SelectedIndexChanged" />
        </Triggers>
        <ContentTemplate>
            <asp:DropDownList ID="ddl1" runat="server" ClientIDMode="Static" OnSelectedIndexChanged="ddl1_SelectedIndexChanged" AutoPostBack="true" ViewStateMode="Enabled">
                <asp:ListItem Text="--Please select a item--" Value="0" />
            </asp:DropDownList>
        </ContentTemplate>
    </asp:UpdatePanel>

In jQuery, the fn property is just an alias to the prototype property.

The jQuery identifier (or $) is just a constructor function, and all instances created with it, inherit from the constructor's prototype.

A simple constructor function:

function Test() {
  this.a = 'a';
}
Test.prototype.b = 'b';

var test = new Test(); 
test.a; // "a", own property
test.b; // "b", inherited property

A simple structure that resembles the architecture of jQuery:

(function() {
  var foo = function(arg) { // core constructor
    // ensure to use the `new` operator
    if (!(this instanceof foo))
      return new foo(arg);
    // store an argument for this example
    this.myArg = arg;
    //..
  };

  // create `fn` alias to `prototype` property
  foo.fn = foo.prototype = {
    init: function () {/*...*/}
    //...
  };

  // expose the library
  window.foo = foo;
})();

// Extension:

foo.fn.myPlugin = function () {
  alert(this.myArg);
  return this; // return `this` for chainability
};

foo("bar").myPlugin(); // alerts "bar"

I'm confused by one thing: You're planning to create a new naming convention for a new project. Generally you should have a naming convention that is company- or team-wide. If you already have projects that have any form of naming convention, you should not change the convention for a new project. If the convention above is just codification of your existing practices, then you are golden. The more it differs from existing de facto standards the harder it will be to gain mindshare in the new standard.

About the only suggestion I would add is I've taken a liking to _t at the end of types in the style of uint32_t and size_t. It's very C-ish to me although some might complain it's just "reverse" Hungarian.

Beginner

Introductory, no previous programming experience

• C++ Primer * (Stanley Lippman, Josée Lajoie, and Barbara E. Moo) (updated for C++11) Coming at 1k pages, this is a very thorough introduction into C++ that covers just about everything in the language in a very accessible format and in great detail. The fifth edition (released August 16, 2012) covers C++11. [Review]

  ^{* Not to be confused with C++ Primer Plus (Stephen Prata), with a significantly less favorable review.}

• Programming: Principles and Practice Using C++ (Bjarne Stroustrup, 2nd Edition - May 25, 2014) (updated for C++11/C++14) An introduction to programming using C++ by the creator of the language. A good read, that assumes no previous programming experience, but is not only for beginners.

Introductory, with previous programming experience

• A Tour of C++ (Bjarne Stroustrup) (2nd edition for C++17) The “tour” is a quick (about 180 pages and 14 chapters) tutorial overview of all of standard C++ (language and standard library, and using C++11) at a moderately high level for people who already know C++ or at least are experienced programmers. This book is an extended version of the material that constitutes Chapters 2-5 of The C++ Programming Language, 4th edition.

• Accelerated C++ (Andrew Koenig and Barbara Moo, 1st Edition - August 24, 2000) This basically covers the same ground as the C++ Primer, but does so on a fourth of its space. This is largely because it does not attempt to be an introduction to programming, but an introduction to C++ for people who've previously programmed in some other language. It has a steeper learning curve, but, for those who can cope with this, it is a very compact introduction to the language. (Historically, it broke new ground by being the first beginner's book to use a modern approach to teaching the language.) Despite this, the C++ it teaches is purely C++98. [Review]

Best practices

• Effective C++ (Scott Meyers, 3rd Edition - May 22, 2005) This was written with the aim of being the best second book C++ programmers should read, and it succeeded. Earlier editions were aimed at programmers coming from C, the third edition changes this and targets programmers coming from languages like Java. It presents ~50 easy-to-remember rules of thumb along with their rationale in a very accessible (and enjoyable) style. For C++11 and C++14 the examples and a few issues are outdated and Effective Modern C++ should be preferred. [Review]

• Effective Modern C++ (Scott Meyers) This is basically the new version of Effective C++, aimed at C++ programmers making the transition from C++03 to C++11 and C++14.

• Effective STL (Scott Meyers) This aims to do the same to the part of the standard library coming from the STL what Effective C++ did to the language as a whole: It presents rules of thumb along with their rationale. [Review]

Intermediate

• More Effective C++ (Scott Meyers) Even more rules of thumb than Effective C++. Not as important as the ones in the first book, but still good to know.

• Exceptional C++ (Herb Sutter) Presented as a set of puzzles, this has one of the best and thorough discussions of the proper resource management and exception safety in C++ through Resource Acquisition is Initialization (RAII) in addition to in-depth coverage of a variety of other topics including the pimpl idiom, name lookup, good class design, and the C++ memory model. [Review]

• More Exceptional C++ (Herb Sutter) Covers additional exception safety topics not covered in Exceptional C++, in addition to discussion of effective object-oriented programming in C++ and correct use of the STL. [Review]

• Exceptional C++ Style (Herb Sutter) Discusses generic programming, optimization, and resource management; this book also has an excellent exposition of how to write modular code in C++ by using non-member functions and the single responsibility principle. [Review]

• C++ Coding Standards (Herb Sutter and Andrei Alexandrescu) “Coding standards” here doesn't mean “how many spaces should I indent my code?” This book contains 101 best practices, idioms, and common pitfalls that can help you to write correct, understandable, and efficient C++ code. [Review]

• C++ Templates: The Complete Guide (David Vandevoorde and Nicolai M. Josuttis) This is the book about templates as they existed before C++11. It covers everything from the very basics to some of the most advanced template metaprogramming and explains every detail of how templates work (both conceptually and at how they are implemented) and discusses many common pitfalls. Has excellent summaries of the One Definition Rule (ODR) and overload resolution in the appendices. A second edition covering C++11, C++14 and C++17 has been already published. [Review]

• C++ 17 - The Complete Guide (Nicolai M. Josuttis) This book describes all the new features introduced in the C++17 Standard covering everything from the simple ones like 'Inline Variables', 'constexpr if' all the way up to 'Polymorphic Memory Resources' and 'New and Delete with overaligned Data'. [Review]

• C++ in Action (Bartosz Milewski). This book explains C++ and its features by building an application from ground up. [Review]

• Functional Programming in C++ (Ivan Cukic). This book introduces functional programming techniques to modern C++ (C++11 and later). A very nice read for those who want to apply functional programming paradigms to C++.

• Professional C++ (Marc Gregoire, 5th Edition - Feb 2021) Provides a comprehensive and detailed tour of the C++ language implementation replete with professional tips and concise but informative in-text examples, emphasizing C++20 features. Uses C++20 features, such as modules and std::format throughout all examples.

Advanced

• Modern C++ Design (Andrei Alexandrescu) A groundbreaking book on advanced generic programming techniques. Introduces policy-based design, type lists, and fundamental generic programming idioms then explains how many useful design patterns (including small object allocators, functors, factories, visitors, and multi-methods) can be implemented efficiently, modularly, and cleanly using generic programming. [Review]

• C++ Template Metaprogramming (David Abrahams and Aleksey Gurtovoy)

• C++ Concurrency In Action (Anthony Williams) A book covering C++11 concurrency support including the thread library, the atomics library, the C++ memory model, locks and mutexes, as well as issues of designing and debugging multithreaded applications. A second edition covering C++14 and C++17 has been already published. [Review]

• Advanced C++ Metaprogramming (Davide Di Gennaro) A pre-C++11 manual of TMP techniques, focused more on practice than theory. There are a ton of snippets in this book, some of which are made obsolete by type traits, but the techniques, are nonetheless useful to know. If you can put up with the quirky formatting/editing, it is easier to read than Alexandrescu, and arguably, more rewarding. For more experienced developers, there is a good chance that you may pick up something about a dark corner of C++ (a quirk) that usually only comes about through extensive experience.

Reference Style - All Levels

• The C++ Programming Language (Bjarne Stroustrup) (updated for C++11) The classic introduction to C++ by its creator. Written to parallel the classic K&R, this indeed reads very much like it and covers just about everything from the core language to the standard library, to programming paradigms to the language's philosophy. [Review] Note: All releases of the C++ standard are tracked in the question "Where do I find the current C or C++ standard documents?".

• C++ Standard Library Tutorial and Reference (Nicolai Josuttis) (updated for C++11) The introduction and reference for the C++ Standard Library. The second edition (released on April 9, 2012) covers C++11. [Review]

• The C++ IO Streams and Locales (Angelika Langer and Klaus Kreft) There's very little to say about this book except that, if you want to know anything about streams and locales, then this is the one place to find definitive answers. [Review]

C++11/14/17/… References:

• The C++11/14/17 Standard (INCITS/ISO/IEC 14882:2011/2014/2017) This, of course, is the final arbiter of all that is or isn't C++.

The C++17 standard is released in electronic form for 198 Swiss Francs.

• The C++17 standard is available, but seemingly not in an economical form – directly from the ISO it costs 198 Swiss Francs (about $200 US).

The project was announced at CppCon'15 by Bjarne Stroustrup and others and welcomes contributions from the community. Most guidelines are supplemented with a rationale and examples as well as discussions of possible tool support. Many rules are designed specifically to be automatically checkable by static analysis tools.

• The C++ Super-FAQ (Marshall Cline, Bjarne Stroustrup and others) is an effort by the Standard C++ Foundation to unify the C++ FAQs previously maintained individually by Marshall Cline and Bjarne Stroustrup and also incorporating new contributions. The items mostly address issues at an intermediate level and are often written with a humorous tone. Not all items might be fully up to date with the latest edition of the C++ standard yet.

• cppreference.com (C++03/11/14/17/…) (initiated by Nate Kohl) is a wiki that summarizes the basic core-language features and has extensive documentation of the C++ standard library. The documentation is very precise but is easier to read than the official standard document and provides better navigation due to its wiki nature. The project documents all versions of the C++ standard and the site allows filtering the display for a specific version. The project was presented by Nate Kohl at CppCon'14.

Classics / Older

Note: Some information contained within these books may not be up-to-date or no longer considered best practice.

• The Design and Evolution of C++ (Bjarne Stroustrup) If you want to know why the language is the way it is, this book is where you find answers. This covers everything before the standardization of C++.

• Ruminations on C++ - (Andrew Koenig and Barbara Moo) [Review]

• Advanced C++ Programming Styles and Idioms (James Coplien) A predecessor of the pattern movement, it describes many C++-specific “idioms”. It's certainly a very good book and might still be worth a read if you can spare the time, but quite old and not up-to-date with current C++.

• Large Scale C++ Software Design (John Lakos) Lakos explains techniques to manage very big C++ software projects. Certainly, a good read, if it only was up to date. It was written long before C++ 98 and misses on many features (e.g. namespaces) important for large-scale projects. If you need to work in a big C++ software project, you might want to read it, although you need to take more than a grain of salt with it. The first volume of a new edition is released in 2019.

• Inside the C++ Object Model (Stanley Lippman) If you want to know how virtual member functions are commonly implemented and how base objects are commonly laid out in memory in a multi-inheritance scenario, and how all this affects performance, this is where you will find thorough discussions of such topics.

• The Annotated C++ Reference Manual (Bjarne Stroustrup, Margaret A. Ellis) This book is quite outdated in the fact that it explores the 1989 C++ 2.0 version - Templates, exceptions, namespaces and new casts were not yet introduced. Saying that however, this book goes through the entire C++ standard of the time explaining the rationale, the possible implementations, and features of the language. This is not a book to learn programming principles and patterns on C++, but to understand every aspect of the C++ language.

• Thinking in C++ (Bruce Eckel, 2nd Edition, 2000). Two volumes; is a tutorial style free set of intro level books. Downloads: vol 1, vol 2. Unfortunately they're marred by a number of trivial errors (e.g. maintaining that temporaries are automatically const), with no official errata list. A partial 3^rd party errata list is available at http://www.computersciencelab.com/Eckel.htm, but it is apparently not maintained.

• Scientific and Engineering C++: An Introduction to Advanced Techniques and Examples (John Barton and Lee Nackman) It is a comprehensive and very detailed book that tried to explain and make use of all the features available in C++, in the context of numerical methods. It introduced at the time several new techniques, such as the Curiously Recurring Template Pattern (CRTP, also called Barton-Nackman trick). It pioneered several techniques such as dimensional analysis and automatic differentiation. It came with a lot of compilable and useful code, ranging from an expression parser to a Lapack wrapper. The code is still available online. Unfortunately, the books have become somewhat outdated in the style and C++ features, however, it was an incredible tour-de-force at the time (1994, pre-STL). The chapters on dynamics inheritance are a bit complicated to understand and not very useful. An updated version of this classic book that includes move semantics and the lessons learned from the STL would be very nice.

I had a need for this once. I created a custom UIView class - AlwaysOnTopView.

@interface AlwaysOnTopView : UIView
@end

@implementation AlwaysOnTopView

- (void)observeValueForKeyPath:(NSString *)keyPath ofObject:(id)object change:(NSDictionary *)change context:(void *)context {
    if (object == self.superview && [keyPath isEqual:@"subviews.@count"]) {
        [self.superview bringSubviewToFront:self];
    }

    [super observeValueForKeyPath:keyPath ofObject:object change:change context:context];
}

- (void)willMoveToSuperview:(UIView *)newSuperview {
    if (self.superview) {
        [self.superview removeObserver:self forKeyPath:@"subviews.@count"];
    }

    [super willMoveToSuperview:newSuperview];
}

- (void)didMoveToSuperview {
    [super didMoveToSuperview];

    if (self.superview) {
        [self.superview addObserver:self forKeyPath:@"subviews.@count" options:0 context:nil];
    }
}

@end

Have your view extend this class. Of course this only ensures a subview is above all of its sibling views.

As you can see no version higher than 2.9.0 has been published to the npm repository. Strangely they have versions higher than this on GitHub. I would suggest opening an issue with the maintainers on this.

For now you can manually install the package via the tarball URL of the required release:

npm install https://github.com/ionic-team/ionic-native/tarball/v3.5.0

Here is a simple solution:

import pandas as pd
# convert the timestamp column to datetime
df['timestamp'] = pd.to_datetime(df['timestamp'])

# extract hour from the timestamp column to create an time_hour column
df['time_hour'] = df['timestamp'].dt.hour

You're right, it's localhost\SQLEXPRESS (just no $) and yes, it's the same for both 2005 and 2008 express versions.

Though the standard process is to login and then push to docker registry, trick to get over this particular problem is to login by providing username and password in same line.

So :

docker login -u xxx -p yyy sampledockerregistry.com/myapp 
docker push sampledockerregistry.com/myapp

Works

whereas

docker login sampledockerregistry.com 
username : xxx
password : yyy
Login Succeeded

docker push sampledockerregistry.com/myapp

Fails

Try uninstalling either Node.js Tools for Visual Studio (NTVS) or the commercial add-on called ReSharper from JetBrains. Using both NTVS and Resharper causes memory leaks in Visual Studio 2015.

NTVS = Node Tools for Visual Studio

Cause: The error occurred since hibernate is not able to connect to the database.
Solution:
1. Please ensure that you have a database present at the server referred to in the configuration file eg. "hibernatedb" in this case.
2. Please see if the username and password for connecting to the db are correct.
3. Check if relevant jars required for the connection are mapped to the project.

I got the same issue and found that it was due to wrong parameters. In views.py, I used:

return render(request, 'demo.html',{'items', items})    

But I found the issue: {'items', items}. Changing to {'items': items} resolved the issue.

Use git rebase --interactive to edit that earlier commit, run git reset HEAD~, and then git add -p to add some, then make a commit, then add some more and make another commit, as many times as you like. When you're done, run git rebase --continue, and you'll have all the split commits earlier in your stack.

Important: Note that you can play around and make all the changes you want, and not have to worry about losing old changes, because you can always run git reflog to find the point in your project that contains the changes you want, (let's call it a8c4ab), and then git reset a8c4ab.

Here's a series of commands to show how it works:

mkdir git-test; cd git-test; git init

now add a file A

vi A

add this line:

one

git commit -am one

then add this line to A:

two

git commit -am two

then add this line to A:

three

git commit -am three

now the file A looks like this:

one
two
three

and our git log looks like the following (well, I use git log --pretty=oneline --pretty="%h %cn %cr ---- %s"

bfb8e46 Rose Perrone 4 seconds ago ---- three
2b613bc Rose Perrone 14 seconds ago ---- two
9aac58f Rose Perrone 24 seconds ago ---- one

Let's say we want to split the second commit, two.

git rebase --interactive HEAD~2

This brings up a message that looks like this:

pick 2b613bc two
pick bfb8e46 three

Change the first pick to an e to edit that commit.

git reset HEAD~

git diff shows us that we just unstaged the commit we made for the second commit:

diff --git a/A b/A
index 5626abf..814f4a4 100644
--- a/A
+++ b/A
@@ -1 +1,2 @@
 one
+two

Let's stage that change, and add "and a third" to that line in file A.

git add .

This is usually the point during an interactive rebase where we would run git rebase --continue, because we usually just want to go back in our stack of commits to edit an earlier commit. But this time, we want to create a new commit. So we'll run git commit -am 'two and a third'. Now we edit file A and add the line two and two thirds.

git add . git commit -am 'two and two thirds' git rebase --continue

We have a conflict with our commit, three, so let's resolve it:

We'll change

one
<<<<<<< HEAD
two and a third
two and two thirds
=======
two
three
>>>>>>> bfb8e46... three

to

one
two and a third
two and two thirds
three

git add .; git rebase --continue

Now our git log -p looks like this:

I was getting the issue 'Newtonsoft.Json' already has a dependency defined for 'Microsoft.CSharp' on the TeamCity build server. I changed the "Update Mode" of the Nuget Installer build step from solution file to packages.config and NuGet.exe to the latest version (I had 3.5.0) and it worked !!

# mysqladmin -u root -p status

Output:

Enter password:
Uptime: 4  Threads: 1  Questions: 62  Slow queries: 0  Opens: 51  Flush tables: 1  Open tables: 45  Queries per second avg: 15.500

It means MySQL serer is running

If server is not running then it will dump error as follows

# mysqladmin -u root -p status

Output :

mysqladmin: connect to server at 'localhost' failed
error: 'Can't connect to local MySQL server through socket '/var/run/mysqld/mysqld.sock' (2)'
Check that mysqld is running and that the socket: '/var/run/mysqld/mysqld.sock' exists!

So Under Debian Linux you can type following command

# /etc/init.d/mysql status

The below code worked for me :)

window.open('your current page URL', '_self', '');
window.close();

you would have to write down some method to create a temporary array and then copy it like

public String[] increaseArray(String[] theArray, int increaseBy)  
{  
    int i = theArray.length;  
    int n = ++i;  
    String[] newArray = new String[n];  
    for(int cnt=0;cnt<theArray.length;cnt++)
    {  
        newArray[cnt] = theArray[cnt];  
    }  
    return newArray;  
}  

or The ArrayList would be helpful to resolve your problem.

If we have to answer the question: String is a reference type and it behaves as a reference. We pass a parameter that holds a reference to, not the actual string. The problem is in the function:

public static void TestI(string test)
{
    test = "after passing";
}

The parameter test holds a reference to the string but it is a copy. We have two variables pointing to the string. And because any operations with strings actually create a new object, we make our local copy to point to the new string. But the original test variable is not changed.

The suggested solutions to put ref in the function declaration and in the invocation work because we will not pass the value of the test variable but will pass just a reference to it. Thus any changes inside the function will reflect the original variable.

I want to repeat at the end: String is a reference type but since its immutable the line test = "after passing"; actually creates a new object and our copy of the variable test is changed to point to the new string.

Weight sum works exactly as you want (like other answers you don't have to sum all the weights on parent layout). On child view specify the weight you want it to take. Don't forget to specify

android:layout_width="0dp" 

Following is an example

    <LinearLayout
                android:layout_width="500dp"
                android:layout_height="20dp" >

                <TextView
                    android:layout_width="0dp"
                    android:layout_height="match_parent"
                    android:layout_weight="3"
                    android:background="@android:color/holo_green_light"
                    android:gravity="center"
                    android:text="30%"
                    android:textColor="@android:color/white" >
                </TextView>

                <TextView
                    android:layout_width="0dp"
                    android:layout_height="match_parent"
                    android:layout_weight="2"
                    android:background="@android:color/holo_blue_bright"
                    android:gravity="center"
                    android:text="20%"
                    android:textColor="@android:color/white" >
                </TextView>

                <TextView
                    android:layout_width="0dp"
                    android:layout_height="match_parent"
                    android:layout_weight="5"
                    android:background="@android:color/holo_orange_dark"
                    android:gravity="center"
                    android:text="50%"
                    android:textColor="@android:color/white" >
                </TextView>
 </LinearLayout>

This will look like

Use btoa("yourstring")

TypeScript is a superset of Javascript, it can use existing Javascript libraries and web APIs

In many case you will need to add the bodyParser module in your express node app. Then in your app.use part below app.use(express.static('www')); add these 2 lines app.use(bodyParser.urlencoded({ extended: true })); app.use(bodyParser.json());

You should use this.state.check instead of check.value here:

this.setState({check: !this.state.check})

But anyway it is bad practice to do it this way. Much better to move it to separate method and don't write callbacks directly in markup.

If you may want to convert plaintext (not just numbers) to a BigInteger you will run into an exception, if you just try to: new BigInteger("not a Number")

In this case you could do it like this way:

public  BigInteger stringToBigInteger(String string){
    byte[] asciiCharacters = string.getBytes(StandardCharsets.US_ASCII);
    StringBuilder asciiString = new StringBuilder();
    for(byte asciiCharacter:asciiCharacters){
        asciiString.append(Byte.toString(asciiCharacter));
    }
    BigInteger bigInteger = new BigInteger(asciiString.toString());
    return bigInteger;
}

It might be cleaner to take out your inline click handler and do it like this:

$(document).ready(function() {
    $('#button-id').click(function() {
      foo($('#formValueId').val());
    });
});

So I liked a lot of the answers above, but I was looking for something that was a little more random in nature. I also wanted a way to explicitly call out excluded characters. Below is my solution using a view that calls the CRYPT_GEN_RANDOM to get a cryptographic random number. In my example, I only chose a random number that was 8 bytes. Please note, you can increase this size and also utilize the seed parameter of the function if you want. Here is the link to the documentation: https://docs.microsoft.com/en-us/sql/t-sql/functions/crypt-gen-random-transact-sql

CREATE VIEW [dbo].[VW_CRYPT_GEN_RANDOM_8]
AS
SELECT CRYPT_GEN_RANDOM(8) as [value];

The reason for creating the view is because CRYPT_GEN_RANDOM cannot be called directly from a function.

From there, I created a scalar function that accepts a length and a string parameter that can contain a comma delimited string of excluded characters.

CREATE FUNCTION [dbo].[fn_GenerateRandomString]
( 
    @length INT,
    @excludedCharacters VARCHAR(200) --Comma delimited string of excluded characters
)
RETURNS VARCHAR(Max)
BEGIN
    DECLARE @returnValue VARCHAR(Max) = ''
        , @asciiValue INT
        , @currentCharacter CHAR;

    --Optional concept, you can add default excluded characters
    SET @excludedCharacters = CONCAT(@excludedCharacters,',^,*,(,),-,_,=,+,[,{,],},\,|,;,:,'',",<,.,>,/,`,~');

    --Table of excluded characters
    DECLARE @excludedCharactersTable table([asciiValue] INT);

    --Insert comma
    INSERT INTO @excludedCharactersTable SELECT 44;

    --Stores the ascii value of the excluded characters in the table
    INSERT INTO @excludedCharactersTable
    SELECT ASCII(TRIM(value))
    FROM STRING_SPLIT(@excludedCharacters, ',')
    WHERE LEN(TRIM(value)) = 1;

    --Keep looping until the return string is filled
    WHILE(LEN(@returnValue) < @length)
    BEGIN
        --Get a truly random integer values from 33-126
        SET @asciiValue = (SELECT TOP 1 (ABS(CONVERT(INT, [value])) % 94) + 33 FROM [dbo].[VW_CRYPT_GEN_RANDOM_8]);

        --If the random integer value is not in the excluded characters table then append to the return string
        IF(NOT EXISTS(SELECT * 
                        FROM @excludedCharactersTable 
                        WHERE [asciiValue] = @asciiValue))
        BEGIN
            SET @returnValue = @returnValue + CHAR(@asciiValue);
        END
    END

    RETURN(@returnValue);
END

Below is an example of the how to call the function.

SELECT [dbo].[fn_GenerateRandomString](8,'!,@,#,$,%,&,?');

For me, the issue was an old table was using MyISAM and not InnoDB. This fixed it

    $tables = [
        'table_1',
        'table_2'
    ];

    foreach ($tables as $table) {
        \DB::statement('ALTER TABLE ' . $table . ' ENGINE = InnoDB');
    }

You can use dt2.Value.ToString("format"), but of course that requires that dt2 != null, and that negates th use of a nullable type in the first place.

There are several solutions here, but the big question is: How do you want to format a null date?

One point not yet mentioned is that there are a few different types of assembly code. In the most basic form, all numbers used in instructions must be specified as constants. For example:

$1902: BD 37 14 : LDA $1437,X
$1905: 85 03    : STA $03
$1907: 85 09    : STA $09
$1909: CA       : DEX
$190A: 10       : BPL $1902

The above bit of code, if stored at address $1900 in an Atari 2600 cartridge, will display a number of lines in different colors fetched from a table which starts at address $1437. On some tools, typing in an address, along with the rightmost part of the line above, would store to memory the values shown in the middle column, and start the next line with the following address. Typing code in that form was much more convenient than typing in hex, but one had to know the precise addresses of everything.

Most assemblers allow one to use symbolic addresses. The above code would be written more like:

rainbow_lp:
  lda ColorTbl,x
  sta WSYNC
  sta COLUBK
  dex
  bpl rainbow_lp

The assembler would automatically adjust the LDA instruction so it would refer to whatever address was mapped to the label ColorTbl. Using this style of assembler makes it much easier to write and edit code than would be possible if one had to hand-key and hand-maintain all addresses.

var matches = [];
$(".className:checked").each(function() {

I've a solution for bash purists.

The function 'define' helps us to assign a multiline value to a variable. This one takes one positional parameter: the variable name to assign the value.

In the heredoc, optionally there're parameter expansions too!

#!/bin/bash

define ()
{
  IFS=$'\n' read -r -d '' $1
}

Be lucky!

Use the -printcert command like this:

keytool -printcert -file certificate.pem

try this Here is working Demo:

$(function() {
    $('#btnSubmit').bind('click', function(){
        var txtVal =  $('#txtDate').val();
        if(isDate(txtVal))
            alert('Valid Date');
        else
            alert('Invalid Date');
    });

function isDate(txtDate)
{
    var currVal = txtDate;
    if(currVal == '')
        return false;

    var rxDatePattern = /^(\d{4})(\/|-)(\d{1,2})(\/|-)(\d{1,2})$/; //Declare Regex
    var dtArray = currVal.match(rxDatePattern); // is format OK?

    if (dtArray == null) 
        return false;

    //Checks for mm/dd/yyyy format.
    dtMonth = dtArray[3];
    dtDay= dtArray[5];
    dtYear = dtArray[1];        

    if (dtMonth < 1 || dtMonth > 12) 
        return false;
    else if (dtDay < 1 || dtDay> 31) 
        return false;
    else if ((dtMonth==4 || dtMonth==6 || dtMonth==9 || dtMonth==11) && dtDay ==31) 
        return false;
    else if (dtMonth == 2) 
    {
        var isleap = (dtYear % 4 == 0 && (dtYear % 100 != 0 || dtYear % 400 == 0));
        if (dtDay> 29 || (dtDay ==29 && !isleap)) 
                return false;
    }
    return true;
}

});

changed regex is:

var rxDatePattern = /^(\d{4})(\/|-)(\d{1,2})(\/|-)(\d{1,2})$/; //Declare Regex

No one mentioned that case classes are also instances of Product and thus inherit these methods:

def productElement(n: Int): Any
def productArity: Int
def productIterator: Iterator[Any]

where the productArity returns the number of class parameters, productElement(i) returns the i^th parameter, and productIterator allows iterating through them.

THE CORRECT WAY ************************ THE CORRECT WAY

while($rows[] = mysqli_fetch_assoc($result));
array_pop($rows);  // pop the last row off, which is an empty row

Despite this question being rather old, I had to deal with a similar warning and wanted to share what I found out.

First of all this is a warning and not an error. So there is no need to worry too much about it. Basically it means, that Tomcat does not know what to do with the source attribute from context.

This source attribute is set by Eclipse (or to be more specific the Eclipse Web Tools Platform) to the server.xml file of Tomcat to match the running application to a project in workspace.

Tomcat generates a warning for every unknown markup in the server.xml (i.e. the source attribute) and this is the source of the warning. You can safely ignore it.

Clearly HttpContext.Current is not null only if you access it in a thread that handles incoming requests. That's why it works "when i use this code in another class of a page".

It won't work in the scheduling related class because relevant code is not executed on a valid thread, but a background thread, which has no HTTP context associated with.

Overall, don't use Application["Setting"] to store global stuffs, as they are not global as you discovered.

If you need to pass certain information down to business logic layer, pass as arguments to the related methods. Don't let your business logic layer access things like HttpContext or Application["Settings"], as that violates the principles of isolation and decoupling.

Update: Due to the introduction of async/await it is more often that such issues happen, so you might consider the following tip,

In general, you should only call HttpContext.Current in only a few scenarios (within an HTTP module for example). In all other cases, you should use

• Page.Context https://docs.microsoft.com/en-us/dotnet/api/system.web.ui.page.context?view=netframework-4.7.2
• Controller.HttpContext https://docs.microsoft.com/en-us/dotnet/api/system.web.mvc.controller.httpcontext?view=aspnet-mvc-5.2

instead of HttpContext.Current.

You could use klepto, which provides persistent caching to memory, disk, or database.
