In addition, you can use sscanf for some very simple scenarios, for example when you know exactly how many parts the string has and what it consists of. You can also parse the arguments on the fly. Do not use it for user inputs because the function will not report conversion errors.

Example:

char text[] = "1:22:300:4444:-5";
int i1, i2, i3, i4, i5;
sscanf(text, "%d:%d:%d:%d:%d", &i1, &i2, &i3, &i4, &i5);
printf("%d, %d, %d, %d, %d", i1, i2, i3, i4, i5);

Output:

1, 22, 300, 4444, -5

For anything more advanced, strtok() and strtok_r() are your best options, as mentioned in other answers.

try this:

var result = from r in myDataTable.AsEnumerable()  
            where r.Field<string>("Name") != "n/a" &&  
                  r.Field<string>("Name") != "" select r;  
DataTable dtResult = result.CopyToDataTable();  

For those looking for a general strategy for reading and writing a string to file:

First, get a file object

You'll need the storage path. For the internal storage, use:

File path = context.getFilesDir();

For the external storage (SD card), use:

File path = context.getExternalFilesDir(null);

Then create your file object:

File file = new File(path, "my-file-name.txt");

Write a string to the file

FileOutputStream stream = new FileOutputStream(file);
try {
    stream.write("text-to-write".getBytes());
} finally {
    stream.close();
}

Or with Google Guava

String contents = Files.toString(file, StandardCharsets.UTF_8);

Read the file to a string

int length = (int) file.length();

byte[] bytes = new byte[length];

FileInputStream in = new FileInputStream(file);
try {
    in.read(bytes);
} finally {
    in.close();
}

String contents = new String(bytes);   

Or if you are using Google Guava

String contents = Files.toString(file,"UTF-8");

For completeness I'll mention

String contents = new Scanner(file).useDelimiter("\\A").next();

which requires no libraries, but benchmarks 50% - 400% slower than the other options (in various tests on my Nexus 5).

Notes

For each of these strategies, you'll be asked to catch an IOException.

The default character encoding on Android is UTF-8.

If you are using external storage, you'll need to add to your manifest either:

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

or

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

Write permission implies read permission, so you don't need both.

What about CassandraDB, Project Voldemort, TokyoCabinet?

Try add it on AppDelegate.swift (inside application method):

UITabBar.appearance().tintColor = UIColor(red: 0/255.0, green: 0/255.0, blue: 0/255.0, alpha: 1.0)

// For WHITE color: 
UITabBar.appearance().tintColor = UIColor(red: 255/255.0, green: 255/255.0, blue: 255/255.0, alpha: 1.0)

Example:

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
    // Tab bar icon selected color
    UITabBar.appearance().tintColor = UIColor(red: 0/255.0, green: 0/255.0, blue: 0/255.0, alpha: 1.0)
    // For WHITE color: UITabBar.appearance().tintColor = UIColor(red: 255/255.0, green: 255/255.0, blue: 255/255.0, alpha: 1.0)
    return true
}

You should disable Power Save Mode

If your test and webapp are in the same Maven project, you can use a property in the project POM. Then you can filter certain files which will allow Maven to set the property in those files. There are different ways to filter, but the most common is during the resources phase - http://books.sonatype.com/mvnref-book/reference/resource-filtering-sect-description.html

If the test and webapp are in different Maven projects, you can put the property in settings.xml, which is in your maven repository folder (C:\Documents and Settings\username.m2) on Windows. You will still need to use filtering or some other method to read the property into your test and webapp.

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

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

    DateFormat format = new SimpleDateFormat(FORMATER);

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

Full example here.

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

Solution in ES6/TypeScript:

let d = new Date;
console.log(d, [`${d.getFullYear()}`, `0${d.getMonth()}`.substr(-2), `0${d.getDate()}`.substr(-2)].join("-"));

var inputs = $('input, select, textarea').keypress(function (e) {
  if (e.which == 13) {
    e.preventDefault();
    var nextInput = inputs.get(inputs.index(this) + 1);
    if (nextInput) {
      nextInput.focus();
    }
  }
});

On Mac OS X (10.12.6), I resolved this issue by doing the following:

brew uninstall --force node
brew install node

I then got an error complaining that node postinstall failed, and to rerun brew postinstall node

I then got an error:

permission denied @ rb_sysopen /usr/local/lib/node_modules/npm/bin/npx

I resolved that error by:

sudo chown -R $(whoami):admin /usr/local/lib/node_modules

And now I don't get this error any more.

I've just noticed that the answer that I upvoted and commented on is ambiguous. So the following is exactly what worked for me. I'm currently on Moment 2.26.0 and TS 3.8.3:

In code:

import moment from 'moment';

In TS config:

{
  "compilerOptions": {
    "esModuleInterop": true,
    ...
  }
}

I am building for both CommonJS and EMS so this config is imported into other config files.

The insight comes from this answer which relates to using Express. I figured it was worth adding here though, to help anyone who searches in relation to Moment.js, rather than something more general.

Because other answers here claim that s denotes the area of the marker, I'm adding this answer to clearify that this is not necessarily the case.

Size in points^2

The argument s in plt.scatter denotes the markersize**2. As the documentation says

s : scalar or array_like, shape (n, ), optional
size in points^2. Default is rcParams['lines.markersize'] ** 2.

This can be taken literally. In order to obtain a marker which is x points large, you need to square that number and give it to the s argument.

So the relationship between the markersize of a line plot and the scatter size argument is the square. In order to produce a scatter marker of the same size as a plot marker of size 10 points you would hence call scatter( .., s=100).

import matplotlib.pyplot as plt

fig,ax = plt.subplots()

ax.plot([0],[0], marker="o",  markersize=10)
ax.plot([0.07,0.93],[0,0],    linewidth=10)
ax.scatter([1],[0],           s=100)

ax.plot([0],[1], marker="o",  markersize=22)
ax.plot([0.14,0.86],[1,1],    linewidth=22)
ax.scatter([1],[1],           s=22**2)

plt.show()

Connection to "area"

So why do other answers and even the documentation speak about "area" when it comes to the s parameter?

Of course the units of points**2 are area units.

• For the special case of a square marker, marker="s", the area of the marker is indeed directly the value of the s parameter.
• For a circle, the area of the circle is area = pi/4*s.
• For other markers there may not even be any obvious relation to the area of the marker.

In all cases however the area of the marker is proportional to the s parameter. This is the motivation to call it "area" even though in most cases it isn't really.

Specifying the size of the scatter markers in terms of some quantity which is proportional to the area of the marker makes in thus far sense as it is the area of the marker that is perceived when comparing different patches rather than its side length or diameter. I.e. doubling the underlying quantity should double the area of the marker.

What are points?

So far the answer to what the size of a scatter marker means is given in units of points. Points are often used in typography, where fonts are specified in points. Also linewidths is often specified in points. The standard size of points in matplotlib is 72 points per inch (ppi) - 1 point is hence 1/72 inches.

It might be useful to be able to specify sizes in pixels instead of points. If the figure dpi is 72 as well, one point is one pixel. If the figure dpi is different (matplotlib default is fig.dpi=100),

1 point == fig.dpi/72. pixels

While the scatter marker's size in points would hence look different for different figure dpi, one could produce a 10 by 10 pixels^2 marker, which would always have the same number of pixels covered:

import matplotlib.pyplot as plt

for dpi in [72,100,144]:

    fig,ax = plt.subplots(figsize=(1.5,2), dpi=dpi)
    ax.set_title("fig.dpi={}".format(dpi))

    ax.set_ylim(-3,3)
    ax.set_xlim(-2,2)

    ax.scatter([0],[1], s=10**2, 
               marker="s", linewidth=0, label="100 points^2")
    ax.scatter([1],[1], s=(10*72./fig.dpi)**2, 
               marker="s", linewidth=0, label="100 pixels^2")

    ax.legend(loc=8,framealpha=1, fontsize=8)

    fig.savefig("fig{}.png".format(dpi), bbox_inches="tight")

plt.show()

What I wound up doing was: Put time duration in by hand, e.g. 1 min, 03 sec. Simple but effective. It seems Excel overwrote everything else, even when I used the 'custom format' given in some answers.

Adding import 'core-js/es7/array'; to my polyfill.ts fixed the issue for me.

The question is tagged with ubuntu, but the solution of un-commenting the extension=mysqli.dll is specific to windows. I am confused here?!, anyways, first thing run <? php phpinfo ?> and search for mysql* under Configuration heading. If you don't see such a thing implies you have not installed or enabled php-mysql. So first install php-mysql

sudo apt get install php-mysql

This command will install php-mysql depending on the php you have already installed, so no worries about the version!!.

Then comes the unix specific solution, in the php.ini file un-comment the line

extension=msql.so

verify that msql.so is present in /usr/lib/php/<timestamp_folder>, ELSE

extension=path/to/msql.so

Then finally restart the apache and mysql services, and you should now see the mysql section under Configrations heading in phpinfo page

create a view for each subquery is the way to go. Got it working like a charm.

Try resetting your network settings

This one worked for me.

You're looking for the FromBase64Transform class, used with the CryptoStream class.

If you have a string, you can also call Convert.FromBase64String.

The natural question is why not just use grep?! But assuming you can't...

import re
import sys

file = open(sys.argv[2], "r")

for line in file:
     if re.search(sys.argv[1], line):
         print line,

Things to note:

• search instead of match to find anywhere in string
• comma (,) after print removes carriage return (line will have one)
• argv includes python file name, so variables need to start at 1

This doesn't handle multiple arguments (like grep does) or expand wildcards (like the Unix shell would). If you wanted this functionality you could get it using the following:

import re
import sys
import glob

for arg in sys.argv[2:]:
    for file in glob.iglob(arg):
        for line in open(file, 'r'):
            if re.search(sys.argv[1], line):
                print line,

Depends on the database server. MySQL doesn't care, its basically the same thing.

Oracle, DB2, and other enterprise level database solutions make a distinction. Usually a schema is a collection of tables and a Database is a collection of schemas.

A good information: you don't need to check whether the Bundle object is null into the onCreate() method. Use the onRestoreInstanceState() method, which the system calls after the onStart() method. The system calls onRestoreInstanceState() only if there is a saved state to restore, so you do not need to check whether the Bundle is null

Whomever gets nothing back, I think he just has to enclose the result in html tags,

Like this:

<html>
<head></head>
<body>
<?php
echo $_GET['link'];
?>

</html>

The date filter always formats the dates using the local timezone. You'll have to write your own filter, based on the getUTCXxx() methods of Date, or on a library like moment.js.

Dynamitey is an open source .net std library, that let's you call it like the dynamic keyword, but using the a string for the property name rather than the compiler doing it for you, and it ends up being equal to reflection speedwise (which is not nearly as fast as using the dynamic keyword, but this is due to the extra overhead of caching dynamically, where the compiler caches statically).

Dynamic.InvokeGet(d,"value2");

Try this!

git log | grep -b3 "Build 0051"

I think this should help.

class ViewController: UIViewController, UIPopoverPresentationControllerDelegate {

    override func viewDidLoad(){
        super.viewDidLoad()

        let when = DispatchTime.now() + 0.5

            // to test after 05.secs... :)
            self.showPopover(base: self.view)

        })

}


func showPopover(base: UIView) {
    if let viewController = self.storyboard?.instantiateViewController(withIdentifier: "popover") as? PopOverViewController {

        let navController = UINavigationController(rootViewController: viewController)
        navController.modalPresentationStyle = .popover

        if let pctrl = navController.popoverPresentationController {
            pctrl.delegate = self

            pctrl.sourceView = base
            pctrl.sourceRect = base.bounds

            self.present(navController, animated: true, completion: nil)
        }
    }
}


@IBAction func onShow(sender: UIButton){
    self.showPopover(base: sender)
}

func adaptivePresentationStyle(for controller: UIPresentationController, traitCollection: UITraitCollection) -> UIModalPresentationStyle{
    return .none
}

and experiment in:

func adaptivePresentationStyle...

    return .popover

or: return .pageSheet.... and so on..

1. I added $scope.selectedItem that gets you past your first problem (defaulting the image)
2. I added $scope.setSelectedItem and called it in ng-click. Your final requirements may be different, but using a directive to bind click and change src was overkill, since most of it can be handled with template
3. Notice use of ngSrc to avoid errant server calls on initial load
4. You'll need to adjust some styles to get the image positioned right in the div. If you really need to use background-image, then you'll need a directive like ngSrc that defers setting the background-image style until after real data has loaded.

Would sending the mail as plain-text sort this?

"How to Send a Plain Text Message in Outlook":

• Select Actions | New Mail Message Using | Plain Text from the menu in Outlook.
• Create your message as usual.
• Click Send to deliver it.

Being plain text it shouldn't screw up your code, with "smart" quotes, auto-capitalisation and such.

Another possible option, if this is a common problem within the company perhaps you could setup an internal code-paste site, there's plenty of open-source ones around, like Open Pastebin

Does it mean that I'm blocking reading any input from the Server/Client for this socket for 2000 millisecond and after this time the socket is ready to read data?

No, it means that if no data arrives within 2000ms a SocketTimeoutException will be thrown.

What does it mean timeout expire?

It means the 2000ms (in your case) elapses without any data arriving.

What is the option which must be enabled prior to blocking operation?

There isn't one that 'must be' enabled. If you mean 'may be enabled', this is one of them.

Infinite Timeout menas that the socket does't read anymore?

What a strange suggestion. It means that if no data ever arrives you will block in the read forever.

Don't use string concatenation to pass parameters, just use a data hash:

$.ajax({
    type: 'POST',
    url: 'popup.aspx/GetJewellerAssets',
    contentType: 'application/json; charset=utf-8',
    data: { jewellerId: filter, locale: 'en-US' },
    dataType: 'json',
    success: AjaxSucceeded,
    error: AjaxFailed
});

UPDATE:

As suggested by @Alex in the comments section, an ASP.NET PageMethod expects parameters to be JSON encoded in the request, so JSON.stringify should be applied on the data hash:

$.ajax({
    type: 'POST',
    url: 'popup.aspx/GetJewellerAssets',
    contentType: 'application/json; charset=utf-8',
    data: JSON.stringify({ jewellerId: filter, locale: 'en-US' }),
    dataType: 'json',
    success: AjaxSucceeded,
    error: AjaxFailed
});

You can use any commonly available hash algorithm (eg. SHA-1), which will give you a slightly longer result than what you need. Simply truncate the result to the desired length, which may be good enough.

For example, in Python:

>>> import hashlib
>>> hash = hashlib.sha1("my message".encode("UTF-8")).hexdigest()
>>> hash
'104ab42f1193c336aa2cf08a2c946d5c6fd0fcdb'
>>> hash[:10]
'104ab42f11'

I understand this isn't what OP asked for, but I still think it is worth to point out how to do it with printf. I almost always prefer using it over std::cout (even with no previous C background).

printf("%.2X", a);

'2' defines the precision, 'X' or 'x' defines case.

I've used a variety of python HTTP libs in the past, and I've settled on 'Requests' as my favourite. Existing libs had pretty useable interfaces, but code can end up being a few lines too long for simple operations. A basic PUT in requests looks like:

payload = {'username': 'bob', 'email': '[email protected]'}
>>> r = requests.put("http://somedomain.org/endpoint", data=payload)

You can then check the response status code with:

r.status_code

or the response with:

r.content

Requests has a lot synactic sugar and shortcuts that'll make your life easier.

You could just use VideoLAN. VideoLAN will work as a server (or you can wrap your own C# application around it for more control). There are also .NET wrappers for the viewer that you can use and thus embed in your C# client.

Escape dot. Sample command will be.

grep '0\.00'

This error message comes specifically from the XDebug extension. PHP itself does not have a function nesting limit. Change the setting in your php.ini:

xdebug.max_nesting_level = 200

or in your PHP code:

ini_set('xdebug.max_nesting_level', 200);

As for if you really need to change it (i.e.: if there's a alternative solution to a recursive function), I can't tell without the code.

For me the simple solution works to set cookies in HttpRequestMessage object.

protected async Task<HttpResponseMessage> SendRequest(HttpRequestMessage requestMessage, CancellationToken cancellationToken = default(CancellationToken))
{
    requestMessage.Headers.Add("Cookie", $"<Cookie Name 1>=<Cookie Value 1>;<Cookie Name 2>=<Cookie Value 2>");

    return await _httpClient.SendAsync(requestMessage, cancellationToken).ConfigureAwait(false);
}

Here is a code that works for me, which is a part from the website above combined with my early trials: http://www.codeproject.com/KB/system/DriveDetector.aspx

This basically makes your form listen to windows messages, filters for usb drives and (cd-dvds), grabs the lparam structure of the message and extracts the drive letter.

        {
            DEV_BROADCAST_VOLUME vol = (DEV_BROADCAST_VOLUME)Marshal.PtrToStructure(m.LParam, typeof(DEV_BROADCAST_VOLUME));
            if ((m.WParam.ToInt32() == DBT_DEVICEARRIVAL) &&  (vol.dbcv_devicetype == DBT_DEVTYPVOLUME) )
            {
                MessageBox.Show(DriveMaskToLetter(vol.dbcv_unitmask).ToString());

I hope this help for who meet this problem.

word-wrap has been renamed to overflow-wrap probably to avoid this confusion.

Now this is what we have:

overflow-wrap

The overflow-wrap property is used to specify whether or not the browser may break lines within words in order to prevent overflow when an otherwise unbreakable string is too long to fit in its containing box.

Possible values:

• normal: Indicates that lines may only break at normal word break points.

• break-word: Indicates that normally unbreakable words may be broken at arbitrary points if there are no otherwise acceptable break points in the line.

source.

word-break

The word-break CSS property is used to specify whether to break lines within words.

• normal: Use the default line break rule.
• break-all: Word breaks may be inserted between any character for non-CJK (Chinese/Japanese/Korean) text.
• keep-all: Don't allow word breaks for CJK text. Non-CJK text behavior is the same as for normal.

source.

Now back to your question, the main difference between overflow-wrap and word-break is that the first determines the behavior on an overflow situation, while the later determines the behavior on a normal situation (no overflow). An overflow situation happens when the container doesn't have enough space to hold the text. Breaking lines on this situation doesn't help because there's no space (imagine a box with fix width and height).

So:

• overflow-wrap: break-word: On an overflow situation, break the words.
• word-break: break-all: On a normal situation, just break the words at the end of the line. An overflow is not necessary.

If your constructor is similar to this one:

public Example(String example) {
    if (example == null) {
        throw new NullPointerException();
    }
    //do fun things with valid example here
}

Then, when you run this JUnit test you will get a green bar:

@Test(expected = NullPointerException.class)
public void constructorShouldThrowNullPointerException() {
    Example example = new Example(null);
}

You can just use the method uniq. Assuming your array is ary, call:

ary.uniq{|x| x.user_id}

and this will return a set with unique user_ids.

You could simply return a value from the function:

var response = 0;

function doSomething() {
    // some code
    return 10;
}
response = doSomething();

longcan only take string convertibles which can end in a base 10 numeral. So, the decimal is causing the harm. What you can do is, float the value before calling the long. If your program is on Python 2.x where int and long difference matters, and you are sure you are not using large integers, you could have just been fine with using int to provide the key as well.

So, the answer is long(float('234.89')) or it could just be int(float('234.89')) if you are not using large integers. Also note that this difference does not arise in Python 3, because int is upgraded to long by default. All integers are long in python3 and call to covert is just int

Run a test.

   string coerce:          7.42296099663
   string cast:            8.05654597282
   string fail coerce:     7.14159703255
   string fail cast:       7.87444186211

This was a test that ran each scenario 10,000,000 times. :-)

Co-ercion is 0 + "123"

Casting is (integer)"123"

I think Co-ercion is a tiny bit faster. Oh, and trying 0 + array('123') is a fatal error in PHP. You might want your code to check the type of the supplied value.

My test code is below.

function test_string_coerce($s) {
    return 0 + $s;
}

function test_string_cast($s) {
    return (integer)$s;
}

$iter = 10000000;

print "-- running each text $iter times.\n";

// string co-erce
$string_coerce = new Timer;
$string_coerce->Start();

print "String Coerce test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('123');
}

$string_coerce->Stop();

// string cast
$string_cast = new Timer;
$string_cast->Start();

print "String Cast test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('123');
}

$string_cast->Stop();

// string co-erce fail.
$string_coerce_fail = new Timer;
$string_coerce_fail->Start();

print "String Coerce fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_coerce('hello');
}

$string_coerce_fail->Stop();

// string cast fail
$string_cast_fail = new Timer;
$string_cast_fail->Start();

print "String Cast fail test\n";
for( $i = 0; $i < $iter ; $i++ ) {
    test_string_cast('hello');
}

class Timer {
    var $ticking = null;
    var $started_at = false;
    var $elapsed = 0;

    }
}

multiple criteria can also be implemented through lambda function

sorted_list = sorted(list_to_sort, key=lambda x: (x[1], x[0]))

You can encapsulate your block of code with a try ... catch statement, and when you run your code, if the column doesn't exist it will throw an exception. You can then figure out what specific exception it throws and have it handle that specific exception in a different way if you so desire, such as returning "Column Not Found".

@JaredPar: Yes you can use Shelvesets for reviews but keep in mind that shelvesets can be overwritten by yourself/others and therefore are not long term stable. Therefore for regulatory relevant reviews you should never use a Shelveset as base but rather a checkin (Changeset). For an informal review it is ok but not for a formal (E.g. FTA relevant) review!

cp -R t1/ t2

The trailing slash on the source directory changes the semantics slightly, so it copies the contents but not the directory itself. It also avoids the problems with globbing and invisible files that Bertrand's answer has (copying t1/* misses invisible files, copying `t1/* t1/.*' copies t1/. and t1/.., which you don't want).

As a follow up, if you just want to set a default, pretty sure you can use the ALTER .. SET syntax. Just don't put all the other stuff in there. If you're gonna put the rest of the column definition in, use the MODIFY or CHANGE syntax as per the accepted answer.

Anyway, the ALTER syntax for setting a column default, (since that's what I was looking for when I came here):

ALTER TABLE table_name ALTER COLUMN column_name SET DEFAULT 'literal';

For which 'literal' could also be a number (e.g. ...SET DEFAULT 0). I haven't tried it with ...SET DEFAULT CURRENT_TIMESTAMP but why not eh?

help('nonlocal') The nonlocal statement

---

    nonlocal_stmt ::= "nonlocal" identifier ("," identifier)*

The nonlocal statement causes the listed identifiers to refer to previously bound variables in the nearest enclosing scope. This is important because the default behavior for binding is to search the local namespace first. The statement allows encapsulated code to rebind variables outside of the local scope besides the global (module) scope.

Names listed in a nonlocal statement, unlike to those listed in a global statement, must refer to pre-existing bindings in an enclosing scope (the scope in which a new binding should be created cannot be determined unambiguously).

Names listed in a nonlocal statement must not collide with pre- existing bindings in the local scope.

See also:

PEP 3104 - Access to Names in Outer Scopes
The specification for the nonlocal statement.

Sometimes using   instead of spaces will work. Clearly it has drawbacks, though.

See the first answer to Accessing a matrix element in the "Mat" object (not the CvMat object) in OpenCV C++
Then just loop over all the elements in cout << M.at<double>(0,0); rather than just 0,0

Or better still with the C++ interface:

cv::Mat M;
cout << "M = " << endl << " "  << M << endl << endl;

If you've got a Mac the easiest way to split those would be to use DfontSplitter, available at https://peter.upfold.org.uk/projects/dfontsplitter

Implement both deprecated and non-deprecated methods like below. First one is to handle API level 21 and higher, second one is handle lower than API level 21

I needed to add USE_FRM to the repair statement to make it work.

You probably do not need to be making lists and appending them to make your array. You can likely just do it all at once, which is faster since you can use numpy to do your loops instead of doing them yourself in pure python.

To answer your question, as others have said, you cannot access a nested list with two indices like you did. You can if you convert mean_data to an array before not after you try to slice it:

R = np.array(mean_data)[:,0]

instead of

R = np.array(mean_data[:,0])

But, assuming mean_data has a shape nx3, instead of

R = np.array(mean_data)[:,0]
P = np.array(mean_data)[:,1]
Z = np.array(mean_data)[:,2]

You can simply do

A = np.array(mean_data).mean(axis=0)

which averages over the 0th axis and returns a length-n array

But to my original point, I will make up some data to try to illustrate how you can do this without building any lists one item at a time:

If you are using a Form Control, you can get the same property as ActiveX by using OLEFormat.Object property of the Shape Object. Better yet assign it in a variable declared as OptionButton to get the Intellisense kick in.

Dim opt As OptionButton

With Sheets("Sheet1") ' Try to be always explicit
    Set opt = .Shapes("Option Button 1").OLEFormat.Object ' Form Control
    Debug.Pring opt.Value ' returns 1 (true) or -4146 (false)
End With

But then again, you really don't need to know the value.
If you use Form Control, you associate a Macro or sub routine with it which is executed when it is selected. So you just need to set up a sub routine that identifies which button is clicked and then execute a corresponding action for it.

For example you have 2 Form Control Option Buttons.

Sub CheckOptions()
    Select Case Application.Caller
    Case "Option Button 1"
    ' Action for option button 1
    Case "Option Button 2"
    ' Action for option button 2
    End Select
End Sub

In above code, you have only one sub routine assigned to both option buttons.
Then you test which called the sub routine by checking Application.Caller.
This way, no need to check whether the option button value is true or false.

If all else fails (including not having the timeout command) the concept in this shell script will work:

 #!/bin/bash
 set -u
 ssh $1 "sleep 10 ; uptime" > /tmp/outputfile 2>&1 & PIDssh=$!
 Count=0
 while test $Count -lt 5 && ps -p $PIDssh > /dev/null
 do
    echo -n .
    sleep 1
    Count=$((Count+1))
 done
 echo ""

 if ps -p $PIDssh > /dev/null
 then
    echo "ssh still running, killing it"
    kill -HUP $PIDssh
 else
    echo "Exited"
 fi

I also like to build locators from up to bottom like:

//div[contains(@class,'btn-group')][./button[contains(.,'Arcade Reader')]]/button[@name='settings']

It's pretty simple, as we just search btn-group with button[contains(.,'Arcade Reader')] and get it's button[@name='settings']

That's just another option to build xPath locators

What is the profit of searching wrapper element: you can return it by method (example in java) and just build selenium constructions like:

getGroupByName("Arcade Reader").find("button[name='settings']");
getGroupByName("Arcade Reader").find("button[name='delete']");

or even simplify more

getGroupButton("Arcade Reader", "delete").click();

jQuery has two methods

// First. Get content as HTML
$("#my_div_id").html();

// Second. Get content as text
$("#my_div_id").text();

As of the date of this answer (March 2020) there is a plugin for chrome called CORS unblock that allows you to skip that browser policy. The 'same origin policy' is an important security feature of browsers. Please only install this plugin for development or testing purposes. Do not promote its installation in end client browsers because you compromise the security of users and the chrome community will be forced to remove this plugin from the store.

One way to do that is to set the cascade option on you "One" side of relationship:

class Employee {
   // 

   @OneToMany(cascade = {CascadeType.PERSIST})
   private Set<Vehicles> vehicles = new HashSet<Vehicles>();

   //
}

by this, when you call

Employee savedEmployee = employeeDao.persistOrMerge(newEmployee);

it will save the vehicles too.

In my humble experience with postgres 9.6, cascade delete doesn't work in practice for tables that grow above a trivial size.

• Even worse, while the delete cascade is going on, the tables involved are locked so those tables (and potentially your whole database) is unusable.
• Still worse, it's hard to get postgres to tell you what it's doing during the delete cascade. If it's taking a long time, which table or tables is making it slow? Perhaps it's somewhere in the pg_stats information? It's hard to tell.

In (ANSI) C99, you can use a designated initializer to initialize a structure:

MY_TYPE a = { .flag = true, .value = 123, .stuff = 0.456 };

Edit: Other members are initialized as zero: "Omitted field members are implicitly initialized the same as objects that have static storage duration." (https://gcc.gnu.org/onlinedocs/gcc/Designated-Inits.html)

Since Java 7, you can do it in one line even without using any external libraries:

Files.copy(inputStream, outputPath, StandardCopyOption.REPLACE_EXISTING);

See the API docs.

you might consider using the Relative and Absolute positining.

`.container {  
position: relative;  
}  
.tag {     
position: absolute;   
}`  

I have tested it there, also if you want it to change its position use this as its margin:

top: 20px;
left: 10px;

It will place it 20 pixels from top and 10 pixels from left; but leave this one if not necessary.

You could use \r\n, or System.Environment.NewLine.

Both .done() and .success() are callback functions and they essentially function the same way.

Here's the documentation. The difference is that .success() is deprecated as of jQuery 1.8. You should use .done() instead.

In case you don't want to click the link:

Deprecation Notice

The jqXHR.success(), jqXHR.error(), and jqXHR.complete() callback methods introduced in jQuery 1.5 are deprecated as of jQuery 1.8. To prepare your code for their eventual removal, use jqXHR.done(), jqXHR.fail(), and jqXHR.always() instead.

Calling len() directly on your dictionary works, and is faster than building an iterator, d.keys(), and calling len() on it, but the speed of either will negligible in comparison to whatever else your program is doing.

d = {x: x**2 for x in range(1000)}

len(d)
# 1000

len(d.keys())
# 1000

%timeit len(d)
# 41.9 ns ± 0.244 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

%timeit len(d.keys())
# 83.3 ns ± 0.41 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

//Secure & Encrypte Data
    public static string HashSHA1(string value)
    {
        var sha1 = SHA1.Create();
        var inputBytes = Encoding.ASCII.GetBytes(value);
        var hash = sha1.ComputeHash(inputBytes);
        var sb = new StringBuilder();
        for (var i = 0; i < hash.Length; i++)
        {
            sb.Append(hash[i].ToString("X2"));
        }
        return sb.ToString();
    }

I personally think that sizeof(a) / sizeof(*a) looks cleaner.

I also prefer to define it as a macro:

#define NUM(a) (sizeof(a) / sizeof(*a))

Then you can use it in for-loops, thusly:

for (i = 0; i < NUM(a); i++)

I am assuming what you are trying to achieve is to insert a line after the first few lines of of a textfile.

head -n10 file.txt >> newfile.txt
echo "your line >> newfile.txt
tail -n +10 file.txt >> newfile.txt

If you don't want to rest of the lines from the file, just skip the tail part.

If you need global access, you might need something ugly like this:

#include <stdio.h>

const char *GetString(int bMunged)
{
    static char s0[5] = "ABCD";
    static char s1[5];

    if (bMunged) {
        if (!s1[0])  {
            s1[0] = s0[3]; 
            s1[1] = s0[2];
            s1[2] = s0[1];
            s1[3] = s0[0];
            s1[4] = 0;
        }
        return s1;
    } else {
        return s0;
    }
}

#define S0 GetString(0)
#define S1 GetString(1)

int main()
{
    puts(S0);
    puts(S1);
    return 0;
}

You are adding all defined constraints to self.view which is wrong, as width and height constraint should be added to your newView.

Also, as I understand you want to set constant width and height 100:100. In this case you should change your code to:

var constW = NSLayoutConstraint(item: newView, 
    attribute: .Width, 
    relatedBy: .Equal, 
    toItem: nil, 
    attribute: .NotAnAttribute, 
    multiplier: 1, 
    constant: 100)
newView.addConstraint(constW)

var constH = NSLayoutConstraint(item: newView, 
    attribute: .Height, 
    relatedBy: .Equal, 
    toItem: nil, 
    attribute: .NotAnAttribute, 
    multiplier: 1, 
    constant: 100)
newView.addConstraint(constH)

Click the line number, and then copy and paste the link from the address bar. To select a range, click the number, and then shift click the later number.

Alternatively, the links are a relatively simple format, just append #L<number> to the end for that specific line number, using the link to the file. Here's a link to the third line of the git repository's README:

https://github.com/git/git/blob/master/README#L3

There are three parts:

1. Add a 'shebang' at the top of your script which tells how to execute your script
2. Give the script 'run' permissions.
3. Make the script in your PATH so you can run it from anywhere.

Adding a shebang

You need to add a shebang at the top of your script so the shell knows which interpreter to use when parsing your script. It is generally:

#!path/to/interpretter

To find the path to your python interpretter on your machine you can run the command:

which python

This will search your PATH to find the location of your python executable. It should come back with a absolute path which you can then use to form your shebang. Make sure your shebang is at the top of your python script:

#!/usr/bin/python

Run Permissions

You have to mark your script with run permissions so that your shell knows you want to actually execute it when you try to use it as a command. To do this you can run this command:

chmod +x myscript.py

Add the script to your path

The PATH environment variable is an ordered list of directories that your shell will search when looking for a command you are trying to run. So if you want your python script to be a command you can run from anywhere then it needs to be in your PATH. You can see the contents of your path running the command:

echo $PATH

This will print out a long line of text, where each directory is seperated by a semicolon. Whenever you are wondering where the actual location of an executable that you are running from your PATH, you can find it by running the command:

which <commandname>

Now you have two options: Add your script to a directory already in your PATH, or add a new directory to your PATH. I usually create a directory in my user home directory and then add it the PATH. To add things to your path you can run the command:

export PATH=/my/directory/with/pythonscript:$PATH

Now you should be able to run your python script as a command anywhere. BUT! if you close the shell window and open a new one, the new one won't remember the change you just made to your PATH. So if you want this change to be saved then you need to add that command at the bottom of your .bashrc or .bash_profile

For my problem, I removed the #include <glui.h> statement and it ran without a problem.

A little refresh as for the Visual Studio 2015.

DUMPBIN is being shipped within Common Tools for Visual C++, so be sure to select this feature in the process of installation of Visual Studio. The utility resides at:

C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\

It become available within Developer Command Prompt for VS 2015, which can be executed from Start Menu:

Visual Studio 2015 \ Visual Studio Tools \ Developer Command Prompt for VS2015

If you want to make it available in the regular command prompt, then add the utility's location to the PATH environment variable on your machine.

For everyone stumbling upon this post because pandas gets mentioned, you now have the very elegant and straighforward option of directly accessing the secondary_y axis in pandas with ax.right_ax

So paraphrasing the example initially posted, you would write:

table = sql.read_frame(query,connection)

ax = table[[0, 1]].plot(ylim=(0,100), secondary_y=table[1])
ax.set_ylabel('$')
ax.right_ax.set_ylabel('Your second Y-Axis Label goes here!')

(this is already mentioned in these posts as well: 1 2)

import json
row = [1L,[0.1,0.2],[[1234L,1],[134L,2]]]
row_json = json.dumps(row)

Check a bit at an arbitrary location in a variable of arbitrary type:

#define bit_test(x, y)  ( ( ((const char*)&(x))[(y)>>3] & 0x80 >> ((y)&0x07)) >> (7-((y)&0x07) ) )

Sample usage:

int main(void)
{
    unsigned char arr[8] = { 0x01, 0x23, 0x45, 0x67, 0x89, 0xAB, 0xCD, 0xEF };

    for (int ix = 0; ix < 64; ++ix)
        printf("bit %d is %d\n", ix, bit_test(arr, ix));

    return 0;
}

Notes: This is designed to be fast (given its flexibility) and non-branchy. It results in efficient SPARC machine code when compiled Sun Studio 8; I've also tested it using MSVC++ 2008 on amd64. It's possible to make similar macros for setting and clearing bits. The key difference of this solution compared with many others here is that it works for any location in pretty much any type of variable.

run the following script provided by conda in your terminal:

source /opt/conda/etc/profile.d/conda.sh - you may need to adjust the path to your conda installtion folder.

after that your zsh will recognize conda and you can run conda init this will modify your .zshrc file automatically for you. It will add something like that at the end of it:

# >>> conda initialize >>>
# !! Contents within this block are managed by 'conda init' !!
__conda_setup="$('/opt/conda/bin/conda' 'shell.zsh' 'hook' 2> /dev/null)"
if [ $? -eq 0 ]; then
    eval "$__conda_setup"
else
    if [ -f "/opt/conda/etc/profile.d/conda.sh" ]; then
        . "/opt/conda/etc/profile.d/conda.sh"
    else
        export PATH="/opt/conda/bin:$PATH"

you can use this:

 var list = new SelectList(countryList, "Id", "Name");
 ViewBag.countries=list;
 @Html.DropDownList("countries",ViewBag.countries as SelectList)

A solution for the stripped white space in SET /P:

the trick is that backspace char which you can summon in the text editor EDIT for DOS. To create it in EDIT press ctrlP+ctrlH. I would paste it here but this webpage can't display it. It's visible on Notepad though (it's werid, like a small black rectangle with a white circle in the center)

So you write this:

<nul set /p=.9    Hello everyone

The dot can be any char, it's only there to tell SET /P that the text starts there, before the spaces, and not at the "Hello". The "9" is a representation of the backspace char that I can't display here. You have to put it instead of the 9, and it will delete the "." , after which you'll get this:

    Hello Everyone

instead of:

Hello Everyone

I hope it helps

I copied and pasted the whole line git clone http://....

The character between git clone and http://... looks like a space, but it is a special Unicode character!

Short answer: After removing this character, and entering a real space, it worked!

For people who love details: I see two ways to reveal ascii vs special-unicode-characters

Way1: Python

Here is the real line:

vi t.txt # copy+paste the line
python
open('t.txt').read()
git clone \xe2\x80\x8b\xe2\x80\x8bhttp://...

Way2: less

vi t.txt # copy+paste the line
LESSCHARSET=ascii less vi.txt

If it looks like git clone <E2><80><8B><E2><80><8B>http://, then you copy+pasted special-unicode-characters.

Put this at the top of your .py file (for python 2.x)

#!/usr/bin/env python 

or for python 3.x

#!/usr/bin/env python3

This should look up the python environment, without it, it will execute the code as if it were not python code, but straight to the CLI. If you need to specify a manual location of python environment put

#!/#path/#to/#python

Try this:

if (items.elementAt(1) instanceof Double) {
   sum.add( i, items.elementAt(1));
}

myString.Contain("someString");  // equal with myString LIKE '%someString%'
myString.EndWith("someString");  // equal with myString LIKE '%someString'
myString.StartWith("someString");  // equal with myString LIKE 'someString%'

Write a function lensort to sort a list of strings based on length.

def lensort(a):
    n = len(a)
    for i in range(n):
        for j in range(i+1,n):
            if len(a[i]) > len(a[j]):
                temp = a[i]
                a[i] = a[j]
                a[j] = temp
    return a
print lensort(["hello","bye","good"])

Are you putting this line inside the class declaration? In that case you should remove the JSONDeserializer::.

One of the Related posts gave me the (simple) answer.

Apparently the auto value on the grid-template-rows property does exactly what I was looking for.

.grid {
    display:grid;
    grid-template-columns: 1fr 1.5fr 1fr;
    grid-template-rows: auto auto 1fr 1fr 1fr auto auto;
    grid-gap:10px;
    height: calc(100vh - 10px);
}

That's because the result of adding two Int16 is an Int32. Check the "conversions" paragraph here: http://msdn.microsoft.com/en-us/library/ybs77ex4%28v=vs.71%29.aspx

Am I getting it because the act of calling it via e.extractAll("th") also passes in self as an argument?

Yes, that's precisely it. If you like, the first parameter is the object name, e that you are calling it with.

And if so, by removing the self in the call, would I be making it some kind of class method that can be called like Extractor.extractAll("th")?

Not quite. A classmethod needs the @classmethod decorator, and that accepts the class as the first paramater (usually referenced as cls). The only sort of method that is given no automatic parameter at all is known as a staticmethod, and that again needs a decorator (unsurprisingly, it's @staticmethod). A classmethod is used when it's an operation that needs to refer to the class itself: perhaps instantiating objects of the class; a staticmethod is used when the code belongs in the class logically, but requires no access to class or instance.

But yes, both staticmethods and classmethods can be called by referencing the classname as you describe: Extractor.extractAll("th").

Postfix form of ++,-- operator follows the rule use-then-change ,

Prefix form (++x,--x) follows the rule change-then-use.

Example 1:

When multiple values are cascaded with << using cout then calculations(if any) take place from right-to-left but printing takes place from left-to-right e.g., (if val if initially 10)

 cout<< ++val<<" "<< val++<<" "<< val;

will result into

12    10    10 

Example 2:

In Turbo C++, if multiple occurrences of ++ or (in any form) are found in an expression, then firstly all prefix forms are computed then expression is evaluated and finally postfix forms are computed e.g.,

int a=10,b;
b=a++ + ++a + ++a + a;
cout<<b<<a<<endl;

It's output in Turbo C++ will be

48 13

Whereas it's output in modern day compiler will be (because they follow the rules strictly)

45 13

• Note: Multiple use of increment/decrement operators on same variable in one expression is not recommended. The handling/results of such
  expressions vary from compiler to compiler.

When you inherit from Super this is what in reality happens:

public class Son extends Super{

  // If you dont declare a constructor of any type, adefault one will appear.
  public Son(){
    // If you dont call any other constructor in the first line a call to super() will be placed instead.
    super();
  }

}

So, that is the reason, because you have to call your unique constructor, since"Super" doesn't have a default one.

Now, trying to guess why Java doesn't support constructor inheritance, probably because a constructor only makes sense if it's talking about concrete instances, and you shouldn't be able to create an instance of something when you don't know how it's defined (by polymorphism).

Earlier when I wasn't granted permission to access the repo, I had also added the SSH pubkey to gitlab. At the point I could access the repo and run go mod vendor, the same problem as your happens. (maybe because of cache)

go mod vendor

go: errors parsing go.mod:
/Users/macos/Documents/sample/go.mod:22: git ls-remote -q https://git.aaa.team/core/some_repo.git in /Users/macos/go/pkg/mod/cache/vcs/a94d20a18fd56245f5d0f9f1601688930cad7046e55dd453b82e959b12d78369: exit status 128:
    fatal: could not read Username for 'https://git.aaa.team': terminal prompts disabled

After a while trying, I decide to remove the SSH key and terminal prompts filling in username and password. Everything is fine then!

If you want to migrate a #git repository from one server to a new one you can do it like this:

git clone OLD_REPOSITORY_PATH
cd OLD_REPOSITORY_DIR
git remote add NEW_REPOSITORY_ALIAS  NEW_REPOSITORY_PATH
#check out all remote branches 
for remote in `git branch -r | grep -v master `; do git checkout --track $remote ; done
git push --mirror NEW_REPOSITORY_PATH
git push NEW_REPOSITORY_ALIAS --tags

All remote branches and tags from the old repository will be copied to the new repository.

Running this command alone:

git push NEW_REPOSITORY_ALIAS

would only copy a master branch (only tracking branches) to the new repository.

One way to do this that correctly uses group by:

select l.* 
from table l
inner join (
  select 
    m_id, max(timestamp) as latest 
  from table 
  group by m_id
) r
  on l.timestamp = r.latest and l.m_id = r.m_id
order by timestamp desc

How this works:

• selects the latest timestamp for each distinct m_id in the subquery
• only selects rows from table that match a row from the subquery (this operation -- where a join is performed, but no columns are selected from the second table, it's just used as a filter -- is known as a "semijoin" in case you were curious)
• orders the rows

string name= "abc";
IList<string> strList = new List<string>() { "abc",  "def", "ghi", "jkl", "mno" };
if (strList.Contains(name))
{
  Console.WriteLine("Got It");
}

/////////////////   OR ////////////////////////

IList<int> num = new List<int>();
num.Add(10);
num.Add(20);
num.Add(30);
num.Add(40);

Console.WriteLine(num.Count);   // to count the total numbers in the list

if(num.Contains(20)) {
    Console.WriteLine("Got It");    // if condition to find the number from list
}

I think you're confused because you're running from the REPL, which automatically prints out the value returned when you call a function. In that case, you do get identical output whether you have a function that creates a value, prints it, and throws it away, or you have a function that creates a value and returns it, letting the REPL print it.

However, these are very much not the same thing, as you will realize when you call autoparts with another function that wants to do something with the value that autoparts creates.

 > is it possible to pull in any way a database of an Android device without having to root it? 

yes if your android app creates a file copy of the database that is accessable by everyone.

android protects apps private data so it is not visible/accessable by other apps. a database is private data. your app can of course read the database-file so it can do a file-copy to some public visible file.

an example

$ echo "something" | mailx -s "subject" [email protected]

to send attachment

$ uuencode file file | mailx -s "subject" [email protected]

and to send attachment AND write the message body

$ (echo "something\n" ; uuencode file file) | mailx -s "subject" [email protected]

defaultMember already is an alias - it doesn't need to be the name of the exported function/thing. Just do

import alias from 'my-module';

Alternatively you can do

import {default as alias} from 'my-module';

but that's rather esoteric.

This should work for you:

var movies = _db.Movies.OrderBy(c => c.Category).ThenBy(n => n.Name)

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

html {
    display: table;
    margin: auto;
}

body {
    padding-top: 50px;
    display: table-cell;
}

div {
    margin: auto;
}

This will center align objects and then also center align the items within them to center align multiple objects with different widths.

For me none of the packages mentioned above did help.

I finally managed to install lxml after running:

sudo apt-get install python3.5-dev

Aangular 2 final has updated APIs. They have added many methods for this.

To update the form control from controller do this:

this.form.controls['dept'].setValue(selected.id);

this.form.controls['dept'].patchValue(selected.id);

No need to reset the errors

It doesn't - the C# compiler does :)

So this code:

string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;

actually gets compiled as:

string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);

(Gah - intervening edit removed other bits accidentally.)

The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y which then needs to be copied again as part of the concatenation of (x + y) and z. Instead, we get it all done in one go.

EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:

string x = "";
foreach (string y in strings)
{
    x += y;
}

just ends up as equivalent to:

string x = "";
foreach (string y in strings)
{
    x = string.Concat(x, y);
}

... so this does generate a lot of garbage, and it's why you should use a StringBuilder for such cases. I have an article going into more details about the two which will hopefully answer further questions.

If you must use the label for the formControl. Like the Ant Design Checkbox. It may throw this error while running tests. You can use ngDefaultControl

<label nz-checkbox formControlName="isEnabled" ngDefaultControl>
    Hello
</label>

<nz-switch nzSize="small" formControlName="mandatory" ngDefaultControl></nz-switch>

Use only one server side form tag.

Check your Master page for <form runat="server"> - there should be only one.

Why do you need more than one?

var jsonData = [{"person":"me","age":"30"},{"person":"you","age":"25"}];

for(var i in jsonData){
    var key = i;
    var val = jsonData[i];
    for(var j in val){
        var sub_key = j;
        var sub_val = val[j];
        console.log(sub_key);
    }
}

EDIT

var jsonObj = {"person":"me","age":"30"};
Object.keys(jsonObj);  // returns ["person", "age"]

Object has a property keys, returns an Array of keys from that Object

Chrome, FF & Safari supports Object.keys

I guess the easy way would be to calculate the minimum and maximum of the data you have, then calculate L = max - min. Then you divide L by the desired bin width (I'm assuming this is what you mean by bin size) and use the ceiling of this value as the number of bins.

Tips of using OS-dependent function to terminate C++ thread:

1. std::thread::native_handle() only can get the thread’s valid native handle type before calling join() or detach(). After that, native_handle() returns 0 - pthread_cancel() will coredump.

2. To effectively call native thread termination function(e.g. pthread_cancel()), you need to save the native handle before calling std::thread::join() or std::thread::detach(). So that your native terminator always has a valid native handle to use.

More explanations please refer to: http://bo-yang.github.io/2017/11/19/cpp-kill-detached-thread .

Right should do:

select RIGHT('abcdeffff',4)

Consider just downloading the file with permanent link and gdown preinstalled like here

Arrays in C# are immutable, e.g. string[], int[]. That means you can't resize them. You need to create a brand new array.

Here is the code for Array.Resize:

public static void Resize<T>(ref T[] array, int newSize)
{
    if (newSize < 0)
    {
        throw new ArgumentOutOfRangeException("newSize", Environment.GetResourceString("ArgumentOutOfRange_NeedNonNegNum"));
    }
    T[] sourceArray = array;
    if (sourceArray == null)
    {
        array = new T[newSize];
    }
    else if (sourceArray.Length != newSize)
    {
        T[] destinationArray = new T[newSize];
        Copy(sourceArray, 0, destinationArray, 0, (sourceArray.Length > newSize) ? newSize : sourceArray.Length);
        array = destinationArray;
    }
}

As you can see it creates a new array with the new size, copies the content of the source array and sets the reference to the new array. The hint for this is the ref keyword for the first parameter.

There are lists that can dynamically allocate new slots for new items. This is e.g. List<T>. These contain immutable arrays and resize them when needed (List<T> is not a linked list implementation!). ArrayList is the same thing without Generics (with Object array).

LinkedList<T> is a real linked list implementation. Unfortunately you can add just LinkListNode<T> elements to the list, so you must wrap your own list elements into this node type. I think its use is uncommon.

You can do this programmatically using a VBA macro. You can make the sheet hidden or very hidden:

Sub HideSheet()

    Dim sheet As Worksheet

    Set sheet = ActiveSheet

    ' this hides the sheet but users will be able 
    ' to unhide it using the Excel UI
    sheet.Visible = xlSheetHidden

    ' this hides the sheet so that it can only be made visible using VBA
    sheet.Visible = xlSheetVeryHidden

End Sub

1. Create a salt,
2. Create a hash password with salt
3. Save both hash and salt
4. decrypt with password and salt... so developers cant decrypt password

public class CryptographyProcessor
{
    public string CreateSalt(int size)
    {
        //Generate a cryptographic random number.
          RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider();
         byte[] buff = new byte[size];
         rng.GetBytes(buff);
         return Convert.ToBase64String(buff);
    }


      public string GenerateHash(string input, string salt)
      { 
         byte[] bytes = Encoding.UTF8.GetBytes(input + salt);
         SHA256Managed sHA256ManagedString = new SHA256Managed();
         byte[] hash = sHA256ManagedString.ComputeHash(bytes);
         return Convert.ToBase64String(hash);
      }

      public bool AreEqual(string plainTextInput, string hashedInput, string salt)
      {
           string newHashedPin = GenerateHash(plainTextInput, salt);
           return newHashedPin.Equals(hashedInput); 
      }
 }

It's Really Simple Just go to your styles.xml change the parent Theme to either Theme.AppCompat.Light.NoActionBar or Theme.AppCompat.NoActionbar and you are done.. :)

It is not necessary to encode a colon as %3B in the query, although doing so is not illegal.

URI         = scheme ":" hier-part [ "?" query ] [ "#" fragment ]
query       = *( pchar / "/" / "?" )
pchar         = unreserved / pct-encoded / sub-delims / ":" / "@"
unreserved    = ALPHA / DIGIT / "-" / "." / "_" / "~"
pct-encoded   = "%" HEXDIG HEXDIG
sub-delims    = "!" / "$" / "&" / "'" / "(" / ")" / "*" / "+" / "," / ";" / "="

It also seems that only percent-encoded spaces are valid, as I doubt that space is an ALPHA or a DIGIT

look to the URI specification for more details.

We have resolved the circular dependency(Parent-child Entities) by mapping the child entity instead of parent entity in Grails 4(GORM).

Example:

Class Person {
    String name
}

Class Employee extends Person{
    String empId
}

//Before my code 
Class Address {
    static belongsTo = [person: Person]
}

//We changed our Address class to:
Class Address {
    static belongsTo = [person: Employee]
}

You can use setBounds(x, y, width, height) to specify the position and size of a GUI component if you set the layout to null. Then (x, y) is the coordinate of the upper-left corner of that component.

You should never use the unidirectional @OneToMany annotation because:

1. It generates inefficient SQL statements
2. It creates an extra table which increases the memory footprint of your DB indexes

Now, in your first example, both sides are owning the association, and this is bad.

While the @JoinColumn would let the @OneToMany side in charge of the association, it's definitely not the best choice. Therefore, always use the mappedBy attribute on the @OneToMany side.

public class User{
    @OneToMany(fetch=FetchType.LAZY, cascade = CascadeType.ALL, mappedBy="user")
    public List<APost> aPosts;

    @OneToMany(fetch=FetchType.LAZY, cascade = CascadeType.ALL, mappedBy="user")
    public List<BPost> bPosts;
}

public class BPost extends Post {

    @ManyToOne(fetch=FetchType.LAZY)    
    public User user;
}

public class APost extends Post {

     @ManyToOne(fetch=FetchType.LAZY) 
     public User user;
}

I had this problem couple of weeks ago. I first tried the troubleshooting on the Android developer site, but without luck. After that I reinstalled the Android SDK, which solved my problem.

Just delete key:

HKEY_CURRENT_USER/Software/Microsoft/VCExpress/9.0/Registration

Or run in command line:

reg delete HKCU\Software\Microsoft\VCExpress\9.0\Registration /f

This is correct. You can also do :

A[] a = new A[] { new A("args"), new A("other args"), .. };

This syntax can also be used to create and initialize an array anywhere, such as in a method argument:

someMethod( new A[] { new A("args"), new A("other args"), . . } )

If you don't want to change your database schema (and I would not for this simple query) you can just combine them in the filter like this: WHERE (Address1 + Address2) LIKE '%searchstring%'

T-SQL is not asynchronous, so you really have no choice but to wait until SP2 ends. Luckily, that's what you want.

CREATE PROCEDURE SP1 AS
   EXEC SP2
   PRINT 'Done'

Judging from the answers here and my own experience. The only acceptable answer, if you're planning on being portable is don't use SQL keywords for table, column, or other names.

All these answers work in the various databases but apparently a lot don't support the ANSI solution.

You can use a single group for seconds/minutes. The following expression may suit your needs:

([0-9]+)\s*(seconds|minutes)

Online demo

Try this:

(Get-ChildItem -Path c:\pstbak\*.* -Filter *.pst | ? {
  $_.LastWriteTime -gt (Get-Date).AddDays(-3) 
}).Count

For me it was tls12:

ServicePointManager.SecurityProtocol = SecurityProtocolType.Tls12;

I think you want something along the line of:

Parent:

<Editor name={this.state.fileData} />

Editor:

var Editor = React.createClass({
  displayName: 'Editor',
  propTypes: {
    name: React.PropTypes.string.isRequired
  },
  getInitialState: function() { 
    return {
      value: this.props.name
    };
  },
  handleChange: function(event) {
    this.setState({value: event.target.value});
  },
  render: function() {
    return (
      <form id="noter-save-form" method="POST">
        <textarea id="noter-text-area" name="textarea" value={this.state.value} onChange={this.handleChange} />
        <input type="submit" value="Save" />
      </form>
    );
  }
});

This is basically a direct copy of the example provided on https://facebook.github.io/react/docs/forms.html

Update for React 16.8:

import React, { useState } from 'react';

const Editor = (props) => {
    const [value, setValue] = useState(props.name);

    const handleChange = (event) => {
        setValue(event.target.value);
    };

    return (
        <form id="noter-save-form" method="POST">
            <textarea id="noter-text-area" name="textarea" value={value} onChange={handleChange} />
            <input type="submit" value="Save" />
        </form>
    );
}

Editor.propTypes = {
    name: PropTypes.string.isRequired
};

Well try ini_set('memory_limit', '256M');

134217728 bytes = 128 MB

Or rewrite the code to consume less memory.

The TrimEnd method takes an input character array and not a string. The code below from Dot Net Perls, shows a more efficient example of how to perform the same functionality as TrimEnd.

static string TrimTrailingChars(string value)
{
    int removeLength = 0;
    for (int i = value.Length - 1; i >= 0; i--)
    {
        char let = value[i];
        if (let == '?' || let == '!' || let == '.')
        {
            removeLength++;
        }
        else
        {
            break;
        }
    }
    if (removeLength > 0)
    {
        return value.Substring(0, value.Length - removeLength);
    }
    return value;
}

Set default encoder at the top of your code

import sys
reload(sys)
sys.setdefaultencoding("ISO-8859-1")

Correct way (if you are not trying to reset the value of the hidden_field input) is:

f.hidden_field :method, :value => value_of_the_hidden_field_as_it_comes_through_in_your_form

Where :method is the method that when called on the object results in the value you want

So following the example above:

= simple_form_for @movie do |f|
  = f.hidden :title, "some value"
  = f.button :submit

The code used in the example will reset the value (:title) of @movie being passed by the form. If you need to access the value (:title) of a movie, instead of resetting it, do this:

= simple_form_for @movie do |f|
  = f.hidden :title, :value => params[:movie][:title]
  = f.button :submit

Again only use my answer is you do not want to reset the value submitted by the user.

I hope this makes sense.

I can give a small hack, you can use T-SQL function. Try this:

SELECT ID, PARSENAME(WebsiteName, 2)
FROM dbo.YourTable .....

or

git symbolic-ref HEAD | cut -d/ -f3-

and then again there is the .git/HEAD file which may also be of interest for you.

SELECT @LastChangeDate = GETDATE()

Another reply to your questions (assuming you are on master and already did "git fetch origin" to make you repo aware about remote changes):

1) Commits on remote branch since when local branch was created:

git diff HEAD...origin/master

2) I assume by "working copy" you mean your local branch with some local commits that are not yet on remote. To see the differences of what you have on your local branch but that does not exist on remote branch run:

git diff origin/master...HEAD

3) See the answer by dbyrne.

Swift 4.2

write this in viewDidLoad

// to detect if TextField changed
TextField.addTarget(self, action: #selector(textFieldDidChange(_:)),
                                   for: UIControl.Event.editingChanged)

write this outside viewDidLoad

@objc func textFieldDidChange(_ textField: UITextField) {
    // do something
}

You could change the event by UIControl.Event.editingDidBegin or what ever you want to detect.

It seems that calling sudo update-alternatives --config java effects keytool. Depending on which version of Java is chosen it changes whether or not keytool is on the path. I had to chose the open JDK instead of Oracle's JDK to not get bash: /usr/bin/keytool: No such file or directory.

Use Array.extend instead of Array.push for > 150,000 records.

if (!Array.prototype.extend) {
  Array.prototype.extend = function(arr) {
    if (!Array.isArray(arr)) {
      return this;
    }

    for (let record of arr) {
      this.push(record);
    }

    return this;
  };
}

Be aware of that only 32 bit version of PHP is available on the Windows platform.

Then if you for instance shift << or >> more than by 31 bits, results are unexpectable. Usually the original number instead of zeros will be returned, and it can be a really tricky bug.

Of course if you use 64 bit version of PHP (Unix), you should avoid shifting by more than 63 bits. However, for instance, MySQL uses the 64-bit BIGINT, so there should not be any compatibility problems.

UPDATE: From PHP 7 Windows, PHP builds are finally able to use full 64 bit integers: The size of an integer is platform-dependent, although a maximum value of about two billion is the usual value (that's 32 bits signed). 64-bit platforms usually have a maximum value of about 9E18, except on Windows prior to PHP 7, where it was always 32 bit.

Mini tip:

I had the following scenario:

<a href="/page/">My link text
:after
</a>

I hided the text with font-size: 0, so I could use a FontAwesome icon for it. This worked on Chrome 36, Firefox 31 and IE9+.

I wouldn't recommend color: transparent because the text stil exists and is selectable. Using line-height: 0px didn't allow me to use :after. Maybe because my element was a inline-block.

Visibility: hidden: Didn't allow me to use :after.

text-indent: -9999px;: Also moved the :after element

I suggest you use a wrapper div or paragraph:

<td><p style="width:50%;">Text only allowed to extend 50% of the cell.</p></td>

And you can make a class out of it:

<td class="linebreak"><p>Text only allowed to extend 50% of the cell.</p></td>

td.linebreak p {
    width: 50%;
}

All of this assuming that you meant 50% as in 50% of the cell.

Maybe a little late to reply. I happen to run into the same problem today. I find that on Windows you can change the console encoder to utf-8 or other encoder that can represent your data. Then you can print it to sys.stdout.

First, run following code in the console:

chcp 65001
set PYTHONIOENCODING=utf-8

Then, start python do anything you want.

If possible, open the file in a text editor and try to change the encoding to UTF-8. Otherwise do it programatically at the OS level.

Benoit's solution works, but you really don't need to incur the overhead to draw a shape. Since colors can be drawables, just define a color in a /res/values/colors.xml file:

<?xml version="1.0" encoding="utf-8"?>
<resources>
    <color name="semitransparent_white">#77ffffff</color>
</resources>

And then use as such in your selector:

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

Here's an interesting presentation:

An intro to Backbone.js

Hint (from the slides):

• Rails in the browser? No.
• An MVC framework for JavaScript? Sorta.
• A big fat state machine? YES!

The plugin's author says you should use "square brackets without the quotes", []

http://bassistance.de/2011/10/07/release-validation-plugin-1-9-0/

Release: Validation Plugin 1.9.0: "...Another change should make the setup of forms with hidden elements easier, these are now ignored by default (option “ignore” has “:hidden” now as default). In theory, this could break an existing setup. In the unlikely case that it actually does, you can fix it by setting the ignore-option to “[]” (square brackets without the quotes)."

To change this setting for all forms:

$.validator.setDefaults({ 
    ignore: [],
    // any other default options and/or rules
});

(It is not required that .setDefaults() be within the document.ready function)

OR for one specific form:

$(document).ready(function() {

    $('#myform').validate({
        ignore: [],
        // any other options and/or rules
    });

});

EDIT:

See this answer for how to enable validation on some hidden fields but still ignore others.

EDIT 2:

Before leaving comments that "this does not work", keep in mind that the OP is simply asking about the jQuery Validate plugin and his question has nothing to do with how ASP.NET, MVC, or any other Microsoft framework can alter this plugin's normal expected behavior. If you're using a Microsoft framework, the default functioning of the jQuery Validate plugin is over-written by Microsoft's unobtrusive-validation plugin.

If you're struggling with the unobtrusive-validation plugin, then please refer to this answer instead: https://stackoverflow.com/a/11053251/594235

You can use the below code on your string and you will get the complete string without html part.

string title = "<b> Hulk Hogan's Celebrity Championship Wrestling &nbsp;&nbsp;&nbsp;<font color=\"#228b22\">[Proj # 206010]</font></b>&nbsp;&nbsp;&nbsp; (Reality Series, &nbsp;)".Replace("&nbsp;",string.Empty);            
        string s = Regex.Replace(title, "<.*?>", String.Empty);

We have similar situation right now and as of this answer, I am using laravel 5.6 release.

I will not use your example in the question but mine, because it's related though.

I have route like this:

Route::name('your.name.here')->get('/your/uri', 'YourController@someMethod');

Then in your controller method, make sure you include

use Illuminate\Http\Request;

and this should be above your controller, most likely a default, if generated using php artisan, now to get variable from the url it should look like this:

  public function someMethod(Request $request)
  {
    $foo = $request->input("start");
    $bar = $request->input("limit");

    // some codes here
  }

Regardless of the HTTP verb, the input() method may be used to retrieve user input.

https://laravel.com/docs/5.6/requests#retrieving-input

Hope this help.

#!/bin/bash
IFS=$'\n' read  -d'' -r -a inlines  < testinput
IFS=$'\n' read  -d'' -r -a  outlines < testoutput
counter=0
cat testinput | while read line; 
do
    echo "$((${inlines[$counter]}-${outlines[$counter]}))"
    counter=$(($counter+1))
done
# OR Do like this
counter=0
readarray a < testinput
readarray b < testoutput
cat testinput | while read myline; 
do
    echo value is: $((${a[$counter]}-${b[$counter]}))
    counter=$(($counter+1))
done

You can use the class org.apache.commons.lang.StringEscapeUtils:

String s = StringEscapeUtils.unescapeHtml("Happy & Sad")

It is working.

Use org.apache.commons.lang3.StringUtils:

name = StringUtils.defaultString(city.getName(), "N/A");

To give a very high level overview of both, in short:

1) Pig is a relational algebra over hadoop

2) Hive is a SQL over hadoop (one level above Pig)

I had this problem, a an AJAX Post request that returned some JSON would fail, eventually returning abort, with the:

SCRIPT7002: XMLHttpRequest: Network Error 0x2ef3

error in the console. On other browsers (Chrome, Firefox, Safari) the exact same AJAX request was fine.

Tracked my issue down - investigation revealed that the response was missing the status code. In this case it should have been 500 internal error. This was being generated as part of a C# web application using service stack that requires an error code to be explicitly set.

IE seemed to leave the connection open to the server, eventually it timed out and it 'aborted' the request; despite receiving the content and other headers.

Perhaps there is an issue with how IE is handling the headers in posts.

Updating the web application to correctly return the status code fixed the issue.

Hope this helps someone!

To add slightly to the other answers, if you actually want to catch SIGTERM (the default signal sent by the kill command), you can use syscall.SIGTERM in place of os.Interrupt. Beware that the syscall interface is system-specific and might not work everywhere (e.g. on windows). But it works nicely to catch both:

c := make(chan os.Signal, 2)
signal.Notify(c, os.Interrupt, syscall.SIGTERM)
....

I'd rather not turn an integer into a string, so here's the function I use for this:

def digitize(n, base=10):
    if n == 0:
        yield 0
    while n:
        n, d = divmod(n, base)
        yield d

Examples:

tuple(digitize(123456789)) == (9, 8, 7, 6, 5, 4, 3, 2, 1)
tuple(digitize(0b1101110, 2)) == (0, 1, 1, 1, 0, 1, 1)
tuple(digitize(0x123456789ABCDEF, 16)) == (15, 14, 13, 12, 11, 10, 9, 8, 7, 6, 5, 4, 3, 2, 1)

As you can see, this will yield digits from right to left. If you'd like the digits from left to right, you'll need to create a sequence out of it, then reverse it:

reversed(tuple(digitize(x)))

You can also use this function for base conversion as you split the integer. The following example splits a hexadecimal number into binary nibbles as tuples:

import itertools as it
tuple(it.zip_longest(*[digitize(0x123456789ABCDEF, 2)]*4, fillvalue=0)) == ((1, 1, 1, 1), (0, 1, 1, 1), (1, 0, 1, 1), (0, 0, 1, 1), (1, 1, 0, 1), (0, 1, 0, 1), (1, 0, 0, 1), (0, 0, 0, 1), (1, 1, 1, 0), (0, 1, 1, 0), (1, 0, 1, 0), (0, 0, 1, 0), (1, 1, 0, 0), (0, 1, 0, 0), (1, 0, 0, 0))

Note that this method doesn't handle decimals, but could be adapted to.

Try doing a complete clean of the target/deployment directory for the app to get rid of any stale library jars. Make a fresh build and check that commons-logging.jar is actually being placed in the correct lib folder. It might not be included when you are building the library for the application.

Try this:

SET @num := 0, @type := '';
SELECT `year`, `id`, `rate`,
    @num := if(@type = `id`, @num + 1, 1) AS `row_number`,
    @type := `id` AS `dummy`
FROM (
    SELECT *
    FROM `h`
    WHERE (
        `year` BETWEEN '2000' AND '2009'
        AND `id` IN (SELECT `rid` FROM `table2`) AS `temp_rid`
    )
    ORDER BY `id`
) AS `temph`
GROUP BY `year`, `id`, `rate`
HAVING `row_number`<='5'
ORDER BY `id`, `rate DESC;

Here is my version, which provides writelines() and fileno(), too:

class FlushFile(object):
    def __init__(self, fd):
        self.fd = fd

    def write(self, x):
        ret = self.fd.write(x)
        self.fd.flush()
        return ret

    def writelines(self, lines):
        ret = self.writelines(lines)
        self.fd.flush()
        return ret

    def flush(self):
        return self.fd.flush

    def close(self):
        return self.fd.close()

    def fileno(self):
        return self.fd.fileno()

For MongoDB earlier than 2.6, the command to add a root user is addUser (e.g.)

db.addUser({user:'admin',pwd:'<password>',roles:["root"]})

Yes, you could use either the JavaScript setTimeout() method or setInterval() method to invoke the code that you would like to run. Here's how you might do it with setTimeout:

function executeQuery() {
  $.ajax({
    url: 'url/path/here',
    success: function(data) {
      // do something with the return value here if you like
    }
  });
  setTimeout(executeQuery, 5000); // you could choose not to continue on failure...
}

$(document).ready(function() {
  // run the first time; all subsequent calls will take care of themselves
  setTimeout(executeQuery, 5000);
});

For those of you who want more customization in their splitting function, I wrote a recursive algorithm that splits a given string with a list of characters to split on. I wrote this before I saw the above post. I hope it helps some frustrated programmers.

splitString = function(string, splitters) {
    var list = [string];
    for(var i=0, len=splitters.length; i<len; i++) {
        traverseList(list, splitters[i], 0);
    }
    return flatten(list);
}

traverseList = function(list, splitter, index) {
    if(list[index]) {
        if((list.constructor !== String) && (list[index].constructor === String))
            (list[index] != list[index].split(splitter)) ? list[index] = list[index].split(splitter) : null;
        (list[index].constructor === Array) ? traverseList(list[index], splitter, 0) : null;
        (list.constructor === Array) ? traverseList(list, splitter, index+1) : null;    
    }
}

flatten = function(arr) {
    return arr.reduce(function(acc, val) {
        return acc.concat(val.constructor === Array ? flatten(val) : val);
    },[]);
}

var stringToSplit = "people and_other/things";
var splitList = [" ", "_", "/"];
splitString(stringToSplit, splitList);

Example above returns: ["people", "and", "other", "things"]

Note: flatten function was taken from Rosetta Code

If the input happens to be in a bootstrap modal dialog, the answer is different. Copying from How to Set focus to first text input in a bootstrap modal after shown this is what is required:

$('#myModal').on('shown.bs.modal', function () {
  $('#textareaID').focus();
})  

echo

• Outputs one or more strings separated by commas

• No return value

  e.g. echo "String 1", "String 2"

print

• Outputs only a single string

• Returns 1, so it can be used in an expression

  e.g. print "Hello"

  or, if ($expr && print "foo")

print_r()

• Outputs a human-readable representation of any one value
• Accepts not just strings but other types including arrays and objects, formatting them to be readable
• Useful when debugging
• May return its output as a return value (instead of echoing) if the second optional argument is given

var_dump()

• Outputs a human-readable representation of one or more values separated by commas
• Accepts not just strings but other types including arrays and objects, formatting them to be readable
• Uses a different output format to print_r(), for example it also prints the type of values
• Useful when debugging
• No return value

var_export()

• Outputs a human-readable and PHP-executable representation of any one value
• Accepts not just strings but other types including arrays and objects, formatting them to be readable
• Uses a different output format to both print_r() and var_dump() - resulting output is valid PHP code!
• Useful when debugging
• May return its output as a return value (instead of echoing) if the second optional argument is given

Notes:

• Even though print can be used in an expression, I recommend people avoid doing so, because it is bad for code readability (and because it's unlikely to ever be useful). The precedence rules when it interacts with other operators can also be confusing. Because of this, I personally don't ever have a reason to use it over echo.
• Whereas echo and print are language constructs, print_r() and var_dump()/var_export() are regular functions. You don't need parentheses to enclose the arguments to echo or print (and if you do use them, they'll be treated as they would in an expression).
• While var_export() returns valid PHP code allowing values to be read back later, relying on this for production code may make it easier to introduce security vulnerabilities due to the need to use eval(). It would be better to use a format like JSON instead to store and read back values. The speed will be comparable.

Instead of

background-repeat-x: no-repeat;
background-repeat-y: no-repeat;

which is not correct, use

background-repeat: no-repeat;

try this:

var c=document.getElementById("alpha");
var d=c.toDataURL("image/png");
var w=window.open('about:blank','image from canvas');
w.document.write("<img src='"+d+"' alt='from canvas'/>");

This shows image from canvas on new page, but if you have open popup in new tab setting it shows about:blank in address bar.

EDIT:- though window.open("<img src='"+ c.toDataURL('image/png') +"'/>") does not work in FF or Chrome, following works though rendering is somewhat different from what is shown on canvas, I think transparency is the issue:

window.open(c.toDataURL('image/png'));

The only character that needs escaping is <. (> is meaningless outside of a tag).

Therefore, your "magic" code is:

safestring = unsafestring.replace(/</g,'&lt;');

Mac Installation:

1. Install brew

   ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"
   

2. Update and verify you are good with

   brew update
   brew doctor
   

3. Install mongodb with

   brew install mongodb
   

4. Create folder for mongo data files:

   mkdir -p /data/db
   

5. Set permissions

   sudo chown -R `id -un` /data/db
   

6. Open another terminal window & run and keep running a mongo server/daemon

   mongod
   

7. Return to previous terminal and run a mongodb shell to access data

   mongo
   

To quit each of these later:

1. The Shell:

   quit()
   

2. The Server

   ctrl-c
   

In MVC 4 you can link from one view to another controller passing the Id or Primary Key via

@Html.ActionLink("Select", "Create", "StudentApplication", new { id=item.PersonId }, null) 

Example:

Let's say table A has two children B and C. Then we can use the following syntax to drop all tables.

DROP TABLE IF EXISTS B,C,A;

This can be placed in the beginning of the script instead of individually dropping each table.

Use json_decode to convert the JSON string to a PHP array, then use normal PHP array functions on it.

$json = '[{"var1":"9","var2":"16","var3":"16"},{"var1":"8","var2":"15","var3":"15"}]';
$data = json_decode($json);

var_dump($data[0]['var1']); // outputs '9'

Others have already given good answers on how to generate code at runtime so I thought I would address your second paragraph. I have some experience with this and just want to share a lesson I learned from that experience.

At the very least, I could define an interface that they would be required to implement, then they would provide a code 'section' that implemented that interface.

You may have a problem if you use an interface as a base type. If you add a single new method to the interface in the future all existing client-supplied classes that implement the interface now become abstract, meaning you won't be able to compile or instantiate the client-supplied class at runtime.

I had this issue when it came time to add a new method after about 1 year of shipping the old interface and after distributing a large amount of "legacy" data that needed to be supported. I ended up making a new interface that inherited from the old one but this approach made it harder to load and instantiate the client-supplied classes because I had to check which interface was available.

One solution I thought of at the time was to instead use an actual class as a base type such as the one below. The class itself can be marked abstract but all methods should be empty virtual methods (not abstract methods). Clients can then override the methods they want and I can add new methods to the base class without invalidating existing client-supplied code.

public abstract class BaseClass
{
    public virtual void Foo1() { }
    public virtual bool Foo2() { return false; }
    ...
}

Regardless of whether this problem applies you should consider how to version the interface between your code base and the client-supplied code.

Notice how most of these can only be used WITHOUT a DOCTYPE. I'm looking for the same answer, but I have a DOCTYPE. There is one way to do it with a DOCTYPE however, although it doesn't apply to the style of my site, but it will work on the type of page you want to create:

div#full-size{
    position: absolute;
    top:0;
    bottom:0;
    right:0;
    left:0;
    overflow:hidden;

Now, this was mentioned earlier but I just wanted to clarify that this is normally used with a DOCTYPE, height:100%; only works without a DOCTYPE

Usage:

select replace_foreign_key('user_rates_posts', 'post_id', 'ON DELETE CASCADE');

Function:

CREATE OR REPLACE FUNCTION 
    replace_foreign_key(f_table VARCHAR, f_column VARCHAR, new_options VARCHAR) 
RETURNS VARCHAR
AS $$
DECLARE constraint_name varchar;
DECLARE reftable varchar;
DECLARE refcolumn varchar;
BEGIN

SELECT tc.constraint_name, ccu.table_name AS foreign_table_name, ccu.column_name AS foreign_column_name 
FROM 
    information_schema.table_constraints AS tc 
    JOIN information_schema.key_column_usage AS kcu
      ON tc.constraint_name = kcu.constraint_name
    JOIN information_schema.constraint_column_usage AS ccu
      ON ccu.constraint_name = tc.constraint_name
WHERE constraint_type = 'FOREIGN KEY' 
   AND tc.table_name= f_table AND kcu.column_name= f_column
INTO constraint_name, reftable, refcolumn;

EXECUTE 'alter table ' || f_table || ' drop constraint ' || constraint_name || 
', ADD CONSTRAINT ' || constraint_name || ' FOREIGN KEY (' || f_column || ') ' ||
' REFERENCES ' || reftable || '(' || refcolumn || ') ' || new_options || ';';

RETURN 'Constraint replaced: ' || constraint_name || ' (' || f_table || '.' || f_column ||
 ' -> ' || reftable || '.' || refcolumn || '); New options: ' || new_options;

END;
$$ LANGUAGE plpgsql;

Be aware: this function won't copy attributes of initial foreign key. It only takes foreign table name / column name, drops current key and replaces with new one.

You can use the get_group method:

In [21]: gb.get_group('foo')
Out[21]: 
     A         B   C
0  foo  1.624345   5
2  foo -0.528172  11
4  foo  0.865408  14

Note: This doesn't require creating an intermediary dictionary / copy of every subdataframe for every group, so will be much more memory-efficient than creating the naive dictionary with dict(iter(gb)). This is because it uses data-structures already available in the groupby object.

You can select different columns using the groupby slicing:

In [22]: gb[["A", "B"]].get_group("foo")
Out[22]:
     A         B
0  foo  1.624345
2  foo -0.528172
4  foo  0.865408

In [23]: gb["C"].get_group("foo")
Out[23]:
0     5
2    11
4    14
Name: C, dtype: int64

.phtml was the standard file extension for PHP 2 programs. .php3 took over for PHP 3. When PHP 4 came out they switched to a straight .php.

The older file extensions are still sometimes used, but aren't so common.

Png files can handle transparency. So you could use this question Save plot to image file instead of displaying it using Matplotlib so as to save you graph as a png file.

And if you want to turn all white pixel transparent, there's this other question : Using PIL to make all white pixels transparent?

If you want to turn an entire area to transparent, then there's this question: And then use the PIL library like in this question Python PIL: how to make area transparent in PNG? so as to make your graph transparent.

I had read yesterday that the issue was fixed for someone when that person cleared cookies. I had tried that but it did not work for me.

Checking the following section in DatabaseInterface.class.php,

        define(
            'PMA_MYSQL_INT_VERSION',
            PMA_Util::cacheGet('PMA_MYSQL_INT_VERSION', true)
        );

I figured that somehow cache is the problem. So, I remembered that I was restarting the service instead of doing a start and stop.

# restart the service
systemd restart php-fpm

# start and stop the service
systemd stop php-fpm
systemd start php-fpm

Doing a stop followed by a start fixed the issue for me.

When using text files to import data, I had problems with quotes and how Excel was formatting numbers. For example, my Excel configuration used the comma as decimal separator instead of the dot.

Now I use Microsoft Access 2010 to open my MySql table as linked table. There I can simply copy and paste cells from Excel to Access.

To do this, first install the MySql ODBC driver and create an ODBC connection. Then in access, in the "External Data" tab, open "ODBC Database" dialog and link to any table using the ODBC connection.

Using MySql Workbench, you can also copy and paste your Excel data into the result grid of MySql Workbench. I gave detailed instructions in this answer.

it's easy

every folder of those you downloaded has a different kind of roboto font, means they are different fonts

example: "roboto_regular_macroman"

to use any of them:

1- extract the folder of the font you want to use

2- upload it near the css file

3- now include it in the css file

example for including the font which called "roboto_regular_macroman":

@font-face {
font-family: 'Roboto';
src: url('roboto_regular_macroman/Roboto-Regular-webfont.eot');
src: url('roboto_regular_macroman/Roboto-Regular-webfont.eot?#iefix') format('embedded-opentype'),
     url('roboto_regular_macroman/Roboto-Regular-webfont.woff') format('woff'),
     url('roboto_regular_macroman/Roboto-Regular-webfont.ttf') format('truetype'),
     url('roboto_regular_macroman/Roboto-Regular-webfont.svg#RobotoRegular') format('svg');
font-weight: normal;
font-style: normal;
}

watch for the path of the files, here i uploaded the folder called "roboto_regular_macroman" in the same folder where the css is

then you can now simply use the font by typing font-family: 'Roboto';
