gevang's answer is great. There's another way as well to do this directly by using pcolor. Code:

[X,Y] = meshgrid(-8:.5:8);
R = sqrt(X.^2 + Y.^2) + eps;
Z = sin(R)./R;
figure;
subplot(1,3,1);
pcolor(X,Y,Z); 
subplot(1,3,2);
pcolor(X,Y,Z); shading flat;
subplot(1,3,3);
pcolor(X,Y,Z); shading interp;

Output:

Also, pcolor is flat too, as show here (pcolor is the 2d base; the 3d figure above it is generated using mesh):

Java:

int offset = TimeZone.getDefault().getRawOffset() + TimeZone.getDefault().getDSTSavings();
long now = System.currentTimeMillis() - offset;

Kotlin:

Int offset = TimeZone.getDefault()rawOffset + TimeZone.getDefault().dstSavings
Long now = System.currentTimeMillis() - offset

On the Visual Studio Code Key Bindings page, the section Keyboard Shortcuts Reference has links to a PDF for each major OS. Once open, search for "replace in files" or any other shortcut you might need.

Another way is to use the Command Palette (ctrl/cmd+shift+P) where you can type "replace" to list all related commands, including the one you want:

Replace in Files ctrl/cmd+shift+H

decimal RoundTotal = Total - (int)Total;
if ((double)RoundTotal <= .50)
   Total = (int)Total;
else
   Total = (int)Total + 1;
lblTotal.Text = Total.ToString();

In case you're looking for a more modern way to check to see if a service is running (this will not work for just any old process), then systemctl might be what you're looking for.

Here's the basic command:

systemctl show --property=ActiveState your_service_here

Which will yield very simple output (one of the following two lines will appear depending on whether the service is running or not running):

ActiveState=active
ActiveState=inactive

And if you'd like to know all of the properties you can get:

systemctl show --all your_service_here

If you prefer that alphabetized:

systemctl show --all your_service_here | sort

And the full code to act on it:

service=$1
result=`systemctl show --property=ActiveState $service`
if [[ "$result" == 'ActiveState=active' ]]; then
    echo "$service is running" # Do something here
else
    echo "$service is not running" # Do something else here
fi 

We can call Controller method using Javascript / Jquery very easily as follows:

Suppose following is the Controller method to be called returning an array of some class objects. Let the class is 'A'

public JsonResult SubMenu_Click(string param1, string param2)

    {
       A[] arr = null;
        try
        {
            Processing...
           Get Result and fill arr.

        }
        catch { }


        return Json(arr , JsonRequestBehavior.AllowGet);

    }

Following is the complex type (class)

 public class A
 {

  public string property1 {get ; set ;}

  public string property2 {get ; set ;}

 }

Now it was turn to call above controller method by JQUERY. Following is the Jquery function to call the controller method.

function callControllerMethod(value1 , value2) {
    var strMethodUrl = '@Url.Action("SubMenu_Click", "Home")?param1=value1 &param2=value2'
    $.getJSON(strMethodUrl, receieveResponse);
}


function receieveResponse(response) {

    if (response != null) {
        for (var i = 0; i < response.length; i++) {
           alert(response[i].property1);
        }
    }
}

In the above Jquery function 'callControllerMethod' we develop controller method url and put that in a variable named 'strMehodUrl' and call getJSON method of Jquery API.

receieveResponse is the callback function receiving the response or return value of the controllers method.

Here we made use of JSON , since we can't make use of the C# class object

directly into the javascript function , so we converted the result (arr) in controller method into JSON object as follows:

Json(arr , JsonRequestBehavior.AllowGet);

and returned that Json object.

Now in callback function of the Javascript / JQuery we can make use of this resultant JSON object and work accordingly to show response data on UI.

The sentence "Loading class 'com.mysql.jdbc.Driver'. This is deprecated. The new driver class is 'com.mysql.cj.jdbc.Driver' " is clear. You should use the newer driver, like this:

Class.forName("com.mysql.cj.jdbc.Driver");

And in mysql-connector-java-8.0.17. You would find that Class com.mysql.jdbc.Driver doesn't provide service any more. (You also can found the warning came from here.)

public class Driver extends com.mysql.cj.jdbc.Driver {
    public Driver() throws SQLException {
    }

    static {
        System.err.println("Loading class `com.mysql.jdbc.Driver'. This is deprecated. The new driver class is `com.mysql.cj.jdbc.Driver'. The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.");
    }
}

The sentence 'The driver is automatically registered via the SPI and manual loading of the driver class is generally unnecessary.' It mean that write code like this is ok:

//Class.forName("com.mysql.cj.jdbc.Driver");
Connection conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/world?useSSL=false&serverTimezone=Asia/Shanghai","root","root");

Due to SPI, driver is automatically registered. How does it work? You can find this from java.sql.DriverManager:

private static void ensureDriversInitialized() {
                          ...
    ServiceLoader<Driver> loadedDrivers = ServiceLoader.load(Driver.class);
                          ...
}

And in your mysql-connector-java-XXX.jar, you also can find the file 'java.sql.Driver' in the META-INF\services. The file as follows:

com.mysql.cj.jdbc.Driver

When you run DriverManager.getConnection(), the static block also start running. So driver can be automatically registered with file 'java.sql.Driver'.

And more about SPI -> Difference between SPI and API?.

JSON syntax is not Python syntax. JSON requires double quotes for its strings.

I think you can use layout:weight = 5 instead android:lines = 5 because when you port your app to smaller device - it does it nicely.. well, both attributes will accomplish your job..

This is a simple solution with the function aggregate:

aggregate(order_no ~ name, myvec, function(x) length(unique(x)))

I'm adding this answer because none of the others worked for me.

I had to add a Header Handler to the Proxy:

import java.util.Set;
import java.util.TreeSet;

import javax.xml.namespace.QName;
import javax.xml.soap.SOAPElement;
import javax.xml.soap.SOAPEnvelope;
import javax.xml.soap.SOAPFactory;
import javax.xml.soap.SOAPHeader;
import javax.xml.ws.handler.MessageContext;
import javax.xml.ws.handler.soap.SOAPHandler;
import javax.xml.ws.handler.soap.SOAPMessageContext;

public class SOAPHeaderHandler implements SOAPHandler<SOAPMessageContext> {

    private final String authenticatedToken;

    public SOAPHeaderHandler(String authenticatedToken) {
        this.authenticatedToken = authenticatedToken;
    }

    public boolean handleMessage(SOAPMessageContext context) {
        Boolean outboundProperty =
                (Boolean) context.get(MessageContext.MESSAGE_OUTBOUND_PROPERTY);
        if (outboundProperty.booleanValue()) {
            try {
                SOAPEnvelope envelope = context.getMessage().getSOAPPart().getEnvelope();
                SOAPFactory factory = SOAPFactory.newInstance();
                String prefix = "urn";
                String uri = "urn:xxxx";
                SOAPElement securityElem =
                        factory.createElement("Element", prefix, uri);
                SOAPElement tokenElem =
                        factory.createElement("Element2", prefix, uri);
                tokenElem.addTextNode(authenticatedToken);
                securityElem.addChildElement(tokenElem);
                SOAPHeader header = envelope.addHeader();
                header.addChildElement(securityElem);
            } catch (Exception e) {
                e.printStackTrace();
            }
        } else {
            // inbound
        }
        return true;
    }

    public Set<QName> getHeaders() {
        return new TreeSet();
    }

    public boolean handleFault(SOAPMessageContext context) {
        return false;
    }

    public void close(MessageContext context) {
        //
    }
}

In the proxy, I just add the Handler:

BindingProvider bp =(BindingProvider)basicHttpBindingAuthentication;
bp.getBinding().getHandlerChain().add(new SOAPHeaderHandler(authenticatedToken));
bp.getBinding().getHandlerChain().add(new SOAPLoggingHandler());

I did a bench-mark of the top two answers with Python 3.4 and I found itertools.accumulate is faster than numpy.cumsum under many circumstances, often much faster. However, as you can see from the comments, this may not always be the case, and it's difficult to exhaustively explore all options. (Feel free to add a comment or edit this post if you have further benchmark results of interest.)

Some timings...

For short lists accumulate is about 4 times faster:

from timeit import timeit

def sum1(l):
    from itertools import accumulate
    return list(accumulate(l))

def sum2(l):
    from numpy import cumsum
    return list(cumsum(l))

l = [1, 2, 3, 4, 5]

timeit(lambda: sum1(l), number=100000)
# 0.4243644131347537
timeit(lambda: sum2(l), number=100000)
# 1.7077815784141421

For longer lists accumulate is about 3 times faster:

l = [1, 2, 3, 4, 5]*1000
timeit(lambda: sum1(l), number=100000)
# 19.174508565105498
timeit(lambda: sum2(l), number=100000)
# 61.871223849244416

If the numpy array is not cast to list, accumulate is still about 2 times faster:

from timeit import timeit

def sum1(l):
    from itertools import accumulate
    return list(accumulate(l))

def sum2(l):
    from numpy import cumsum
    return cumsum(l)

l = [1, 2, 3, 4, 5]*1000

print(timeit(lambda: sum1(l), number=100000))
# 19.18597290944308
print(timeit(lambda: sum2(l), number=100000))
# 37.759664884768426

If you put the imports outside of the two functions and still return a numpy array, accumulate is still nearly 2 times faster:

from timeit import timeit
from itertools import accumulate
from numpy import cumsum

def sum1(l):
    return list(accumulate(l))

def sum2(l):
    return cumsum(l)

l = [1, 2, 3, 4, 5]*1000

timeit(lambda: sum1(l), number=100000)
# 19.042188624851406
timeit(lambda: sum2(l), number=100000)
# 35.17324400227517

I was trying to display borders on an empty cell in an HTML table. My old trick of using non-breaking space in empty cells was not working from xslt. I used line break with the same effect. I mention this just in case the reason you were trying to use the non-breaking space was to give some content to an 'empty' table cell in order to turn on the cell borders.

Web API introduced an Attribute [Authorize] to provide security. This can be set globally (global.asx)

public static void Register(HttpConfiguration config)
{
    config.Filters.Add(new AuthorizeAttribute());
}

Or per controller:

[Authorize]
public class ValuesController : ApiController{
...

Of course your type of authentication may vary and you may want to perform your own authentication, when this occurs you may find useful inheriting from Authorizate Attribute and extending it to meet your requirements:

public class DemoAuthorizeAttribute : AuthorizeAttribute
{
    public override void OnAuthorization(System.Web.Http.Controllers.HttpActionContext actionContext)
    {
        if (Authorize(actionContext))
        {
            return;
        }
        HandleUnauthorizedRequest(actionContext);
    }

    protected override void HandleUnauthorizedRequest(System.Web.Http.Controllers.HttpActionContext actionContext)
    {
        var challengeMessage = new System.Net.Http.HttpResponseMessage(System.Net.HttpStatusCode.Unauthorized);
        challengeMessage.Headers.Add("WWW-Authenticate", "Basic");
        throw new HttpResponseException(challengeMessage);
    }

    private bool Authorize(System.Web.Http.Controllers.HttpActionContext actionContext)
    {
        try
        {
            var someCode = (from h in actionContext.Request.Headers where h.Key == "demo" select h.Value.First()).FirstOrDefault();
            return someCode == "myCode";
        }
        catch (Exception)
        {
            return false;
        }
    }
}

And in your controller:

[DemoAuthorize]
public class ValuesController : ApiController{

Here is a link on other custom implemenation for WebApi Authorizations:

java.sql.Timestamp is a subclass of java.util.Date. So, just upcast it.

Date dtStart = resultSet.getTimestamp("dtStart");
Date dtEnd = resultSet.getTimestamp("dtEnd");

Using SimpleDateFormat and creating Joda DateTime should be straightforward from this point on.

Using indexOf and Recursion:

First check if the nth position passed is greater than the total number of substring occurrences. If passed, recursively go through each index until the nth one is found.

var getNthPosition = function(str, sub, n) {
    if (n > str.split(sub).length - 1) return -1;
    var recursePosition = function(n) {
        if (n === 0) return str.indexOf(sub);
        return str.indexOf(sub, recursePosition(n - 1) + 1);
    };
    return recursePosition(n);
};

I use Eclipse Java EE edition

Create a "Dynamic Web Project"

Install a local server in the server view, for the version of Tomcat I'm using. Then debug, and run on that server for testing.

When I deploy I export the project to a war file.

//DIVISORS IN TIME COMPLEXITY sqrt(n)

#include<bits/stdc++.h>
using namespace std;

#define ll long long

int main()
{
    ll int n;
    cin >> n;

    for(ll i = 2;  i <= sqrt(n); i++)
    {
        if (n%i==0)
        {
            if (n/i!=i)
                cout << i << endl << n/i<< endl;
            else
                cout << i << endl;
        }
    }
}

That is the standard way to swap two variables, yes.

Have you considered using ICollection<T> or IList<T> interfaces instead, they exist for the very reason that you want to have an Add method on an IEnumerable<T>.

IEnumerable<T> is used to 'mark' a type as being...well, enumerable or just a sequence of items without necessarily making any guarantees of whether the real underlying object supports adding/removing of items. Also remember that these interfaces implement IEnumerable<T> so you get all the extensions methods that you get with IEnumerable<T> as well.

It is not clear why you want to do this. If you want to get the correct numerical value, you could use unary + ^[docs]:

value = +value;

If you just want to format the text, then regex could be better. It depends on the values you are dealing with I'd say. If you only have integers, then

input.value = +input.value;

is fine as well. Of course it also works for float values, but depending on how many digits you have after the point, converting it to a number and back to a string could (at least for displaying) remove some.

See the defaultValue property of a text input, it's also used when you reset the form by clicking an <input type="reset"/> button (http://www.w3schools.com/jsref/prop_text_defaultvalue.asp )

btw, defaultValue and placeholder text are different concepts, you need to see which one better fits your needs

you can also use good old sscanf.

CString s;
int i;
int j = _stscanf(s, _T("%d"), &i);
if (j != 1)
{
   // tranfer didn't work
}

A simple addClass and removeClass will do the trick on what you need..

$('#change').on('click', function() { 
  $('div').each(function() { 
    if($(this).hasClass('active')) { 
        $(this).removeClass('active');
    } else { 
        $(this).addClass('active');
    }
});

});

Seee fiddle

I recommend you to learn jquery first before using.

Besides the other answers. You should notice these args can give you the file path that was dragged and dropped on the .exe file. i.e if you drag and drop any file on your .exe file then the application will be launched and the arg[0] will contain the file path that was dropped onto it.

static void Main(string[] args)
{
    Console.WriteLine(args[0]);
}

this will print the path of the file dropped on the .exe file. e.g

C:\Users\ABCXYZ\source\repos\ConsoleTest\ConsoleTest\bin\Debug\ConsoleTest.pdb

Hence, looping through the args array will give you the path of all the files that were selected and dragged and dropped onto the .exe file of your console app. See:

static void Main(string[] args)
{
    foreach (var arg in args)
    {
        Console.WriteLine(arg);
    }
    Console.ReadLine();
}

The code sample above will print all the file names that were dragged and dropped onto it, See I am dragging 5 files onto my ConsoleTest.exe app.

And here is the output that I get after that:

No problem. Just use the following. This will behave exactly like serializing a form but using a div's content instead.

$('#divId :input').serialize();

Check https://jsbin.com/xabureladi/1 for a demonstration (https://jsbin.com/xabureladi/1/edit for the code)

It does this by default, you just need to look into the project's /dist folder.

I had similar issue with width property. I couldnt remove the !important from code, and since it needed this style on a new template I added an Id (modalstyling) to the element and afterwards i added following code to the template:

<script type="text/javascript">
    $('#modalstyling').css('width', '');    //Removal of width !important
    $('#modalstyling').width('75%');        //Set custom width
</script>

Use the INTERVAL type to it. E.g:

--yesterday
SELECT NOW() - INTERVAL '1 DAY';

--Unrelated to the question, but PostgreSQL also supports some shortcuts:
SELECT 'yesterday'::TIMESTAMP, 'tomorrow'::TIMESTAMP, 'allballs'::TIME;

Then you can do the following on your query:

SELECT 
    org_id,
    count(accounts) AS COUNT,
    ((date_at) - INTERVAL '1 DAY') AS dateat
FROM 
    sourcetable
WHERE 
    date_at <= now() - INTERVAL '130 DAYS'
GROUP BY 
    org_id,
    dateat;

TIPS

Tip 1

You can append multiple operands. E.g.: how to get last day of current month?

SELECT date_trunc('MONTH', CURRENT_DATE) + INTERVAL '1 MONTH - 1 DAY';

Tip 2

You can also create an interval using make_interval function, useful when you need to create it at runtime (not using literals):

SELECT make_interval(days => 10 + 2);
SELECT make_interval(days => 1, hours => 2);
SELECT make_interval(0, 1, 0, 5, 0, 0, 0.0);

Above answers have enough description for the asked question.

Adding to that, Tensorflow has optimised the operation of applying the activation function then calculating cost using its own activation followed by cost functions. Hence it is a good practice to use: tf.nn.softmax_cross_entropy() over tf.nn.softmax(); tf.nn.cross_entropy()

You can find prominent difference between them in a resource intensive model.

Here's what we ended up doing.

Add this to index.html. It should be the first thing in the <head> section

<base href="/">
<script>
  (function() {
    window['_app_base'] = '/' + window.location.pathname.split('/')[1];
  })();
</script>

Then in the app.module.ts file, add { provide: APP_BASE_HREF, useValue: window['_app_base'] || '/' } to the list of providers, like so:

import { NgModule, enableProdMode, provide } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { APP_BASE_HREF, Location } from '@angular/common';


import { AppComponent, routing, appRoutingProviders, environment } from './';

if (environment.production) {
  enableProdMode();
}

@NgModule({
  declarations: [AppComponent],
  imports: [
    BrowserModule,
    HttpModule,
    routing],
  bootstrap: [AppComponent],
  providers: [
    appRoutingProviders,
    { provide: APP_BASE_HREF, useValue: window['_app_base'] || '/' },
  ]
})
export class AppModule { }

For example, my router IP address is 192.168.1.1 and its USB drive has three share folders as \user1, \user2 and \user3 which separated for three users, then we can add the following three lines in hosts file,

192.168.1.1 server1

192.168.1.1 server2

192.168.1.1 server3

in this example we map the server1 to user #1, server2 to user #2 and server3 to user #3.

After reboot the PC, we can connect the folder \user1 for user #1, \user2 for user #2 and \user3 for user #3 simultaneously in Windows File Explorer, that is

if we type the router name as \\server1 in folder indication field of Explorer, it will show all shared folders of router's USB drive in Explorer right pane and sever1 under "Network" item in left pane of Explorer, then the user #1 may access the share folder \user1.

At this time if we type \\server2 or \\server3 in the directory indication field of Explorer, then we may connect the router's USB drive as server2 or server3 and access the share folder \user2 or \user3 for user #2 or user #3 and keep the "server1" connection simultaneously.

Using this method we may also use the "NET USE" command to do these actions.

This should work:

txtfarmersize = Convert.ToInt32(reader["farmsize"]);

you can test if have exactly some values, by example:

for(MyBoolean b : MyBoolean.values()) {
    switch(b) {
    case TRUE:
        break;
    case FALSE:
        break;
    default:
        throw new IllegalArgumentException(b.toString());
}

for(String s : new String[]{"TRUE", "FALSE" }) {
    MyBoolean.valueOf(s);
}

If someone removes or adds a value, some of test fails.

Add the following to your on button click event:

Intent intent = new Intent(First.this, Second.class);
startActivity(intent);
finish();

This code works to catch the user closing the console window:

using System;
using System.Runtime.InteropServices;

class Program {
    static void Main(string[] args) {
        handler = new ConsoleEventDelegate(ConsoleEventCallback);
        SetConsoleCtrlHandler(handler, true);
        Console.ReadLine();
    }

    static bool ConsoleEventCallback(int eventType) {
        if (eventType == 2) {
            Console.WriteLine("Console window closing, death imminent");
        }
        return false;
    }
    static ConsoleEventDelegate handler;   // Keeps it from getting garbage collected
    // Pinvoke
    private delegate bool ConsoleEventDelegate(int eventType);
    [DllImport("kernel32.dll", SetLastError = true)]
    private static extern bool SetConsoleCtrlHandler(ConsoleEventDelegate callback, bool add);

}

Beware of the restrictions. You have to respond quickly to this notification, you've got 5 seconds to complete the task. Take longer and Windows will kill your code unceremoniously. And your method is called asynchronously on a worker thread, the state of the program is entirely unpredictable so locking is likely to be required. Do make absolutely sure that an abort cannot cause trouble. For example, when saving state into a file, do make sure you save to a temporary file first and use File.Replace().

To get reference to UIViewController having UIView, you could make extension of UIResponder (which is super class for UIView and UIViewController), which allows to go up through the responder chain and thus reaching UIViewController (otherwise returning nil).

extension UIResponder {
    func getParentViewController() -> UIViewController? {
        if self.nextResponder() is UIViewController {
            return self.nextResponder() as? UIViewController
        } else {
            if self.nextResponder() != nil {
                return (self.nextResponder()!).getParentViewController()
            }
            else {return nil}
        }
    }
}

//Swift 3
extension UIResponder {
    func getParentViewController() -> UIViewController? {
        if self.next is UIViewController {
            return self.next as? UIViewController
        } else {
            if self.next != nil {
                return (self.next!).getParentViewController()
            }
            else {return nil}
        }
    }
}

let vc = UIViewController()
let view = UIView()
vc.view.addSubview(view)
view.getParentViewController() //provide reference to vc

Fast to write and convenient to use, with promise and error management:

function copyFile(source, target) {
  var rd = fs.createReadStream(source);
  var wr = fs.createWriteStream(target);
  return new Promise(function(resolve, reject) {
    rd.on('error', reject);
    wr.on('error', reject);
    wr.on('finish', resolve);
    rd.pipe(wr);
  }).catch(function(error) {
    rd.destroy();
    wr.end();
    throw error;
  });
}

The same with async/await syntax:

async function copyFile(source, target) {
  var rd = fs.createReadStream(source);
  var wr = fs.createWriteStream(target);
  try {
    return await new Promise(function(resolve, reject) {
      rd.on('error', reject);
      wr.on('error', reject);
      wr.on('finish', resolve);
      rd.pipe(wr);
    });
  } catch (error) {
    rd.destroy();
    wr.end();
    throw error;
  }
}

Currently, the eyedropper tool is not working in my version of Chrome (as described above), though it worked for me in the past. I hear it is being updated in the latest version of Chrome.

However, I'm able to grab colors easily in Firefox.

1. Open page in Firefox
2. Hamburger Menu -> Web Developer -> Eyedropper
3. Drag eyedropper tool over the image... Click.
   Color is copied to your clipboard, and eyedropper tool goes away.
4. Paste color code

In case you cannot get the eyedropper tool to work in Chrome, this is a good work around.
I also find it easier to access :-)

That's my final and easy to use solution :

public class ManualSelectedSpinner extends Spinner {
    //get a reference for the internal listener
    private OnItemSelectedListener mListener;

    public ManualSelectedSpinner(Context context) {
        super(context);
    }

    public ManualSelectedSpinner(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    public ManualSelectedSpinner(Context context, AttributeSet attrs, int defStyleAttr) {
        super(context, attrs, defStyleAttr);
    }

    @Override
    public void setOnItemSelectedListener(@Nullable OnItemSelectedListener listener) {
        mListener = listener;
        super.setOnItemSelectedListener(listener);
    }

    public void setSelectionWithoutInformListener(int position){
        super.setOnItemSelectedListener(null);
        super.setSelection(position);
        super.setOnItemSelectedListener(mListener);
    }

    public void setSelectionWithoutInformListener(int position, boolean animate){
        super.setOnItemSelectedListener(null);
        super.setSelection(position, animate);
        super.setOnItemSelectedListener(mListener);
    }
}

Use the default setSelection(...) for default behaviour or use setSelectionWithoutInformListener(...) for selecting an item in the spinner without triggering OnItemSelectedListener callback.

I ran into this when checking on a null or empty string

if (x == NULL || x == '') {

changed it to

if (is.null(x) || x == '') {

You need to use double apostrophe instead of single in the "You''re", eg:

String text = java.text.MessageFormat.format("You''re about to delete {0} rows.", 5);
System.out.println(text);

Often, you don't need any auto* tools and the simplest solution is to simply run touch aclocal.m4 configure in the relevant folder (and also run touch on Makefile.am and Makefile.in if they exist). This will update the timestamp of aclocal.m4 and remind the system that aclocal.m4 is up-to-date and doesn't need to be rebuilt. After this, it's probably best to empty your build directory and rerun configure from scratch after doing this. I run into this problem regularly. For me, the root cause is that I copy a library (e.g. mpfr code for gcc) from another folder and the timestamps change.

Of course, this trick isn't valid if you really do need to regenerate those files, perhaps because you have manually changed them. But hopefully the developers of the package distribute up-to-date files.

And of course, if you do want to install automake and friends, then use the appropriate package-manager for your distribution.

Install aclocal which comes with automake:

brew install automake          # for Mac
apt-get install automake       # for Ubuntu

Try again:

./configure && make 

In SQL SERVER 2016 or higher you can use STRING_SPLIT.

DECLARE @InParaSeprated VARCHAR(MAX) = 'ruby,rails,scruffy,rubyonrails'
DECLARE @Delimeter VARCHAR(10) = ','
SELECT 
    * 
FROM 
    Tags T
    INNER JOIN STRING_SPLIT(@InputParameters,@Delimeter) SS ON T.Name = SS.value
ORDER BY 
    Count DESC

I use this because some times join faster than Like Operator works in my queries.
In addition you can put unlimited number of inputs in any separated format that you like.
I like this ..

Compatible with all SDK versions (android.permission.ACCESS_FINE_LOCATION became dangerous permission in Android M and requires user to manually grant it).

In Android versions below Android M ContextCompat.checkSelfPermission(...) always returns true if you add these permission(s) in AndroidManifest.xml)

public void onSomeButtonClick() {
    ...
    if (!permissionsGranted()) {
        ActivityCompat.requestPermissions(this, new String[] {Manifest.permission.ACCESS_FINE_LOCATION}, 123);
    } else doLocationAccessRelatedJob();
    ...
}

private Boolean permissionsGranted() {
    return ContextCompat.checkSelfPermission(this, Manifest.permission.ACCESS_FINE_LOCATION) == PackageManager.PERMISSION_GRANTED);
}

@Override
public void onRequestPermissionsResult(final int requestCode, @NonNull final String[] permissions, @NonNull final int[] grantResults) {
    super.onRequestPermissionsResult(requestCode, permissions, grantResults);
    if (requestCode == 123) {
        if (grantResults.length > 0 && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
            // Permission granted.
            doLocationAccessRelatedJob();
        } else {
            // User refused to grant permission. You can add AlertDialog here
            Toast.makeText(this, "You didn't give permission to access device location", Toast.LENGTH_LONG).show();
            startInstalledAppDetailsActivity();
        }
    }
}

private void startInstalledAppDetailsActivity() {
    Intent i = new Intent();
    i.setAction(Settings.ACTION_APPLICATION_DETAILS_SETTINGS);
    i.addCategory(Intent.CATEGORY_DEFAULT);
    i.setData(Uri.parse("package:" + getPackageName()));
    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
    startActivity(i);
}

in AndroidManifest.xml:

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

The :nth-child(n) selector matches every element that is the nth child, regardless of type, of its parent. Odd and even are keywords that can be used to match child elements whose index is odd or even (the index of the first child is 1).

this is what you want:

<html>
    <head>
        <style>
            li { color: blue }<br>
            li:nth-child(even) { color:red }
            li:nth-child(odd) { color:green}
        </style>
    </head>
    <body>
        <ul>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
            <li>ho</li>
        </ul>
    </body>
</html>

It is actually possible only using CSS, however, the image you use to replace must be the same size as the original facebook log in button. Fortunately Facebook delivers the button in different sizes.

From facebook:

size - Different sized buttons: small, medium, large, xlarge - the default is medium. https://developers.facebook.com/docs/reference/plugins/login/

Set the login iframe opacity to 0 and show a background image in the parent div

.fb_iframe_widget iframe {
    opacity: 0;
}

.fb_iframe_widget {
  background-image: url(another-button.png);
  background-repeat: no-repeat; 
}

If you use an image that is bigger than the original facebook button, the part of the image that is outside the width and height of the original button will not be clickable.

Definitely possible with any number of libraries and/or HTML5 technologies. You could possible hack something together in pure CSS by using something like the border-bottom property, but it would probably be horribly hacky.

If you're serious about this, you should take a look at a JS library for canvas drawing or SVG. For example, something like http://www.graphjs.org/ or http://jsdraw2dx.jsfiction.com/

Pandas is based on NumPy arrays. The key to speed with NumPy arrays is to perform your operations on the whole array at once, never row-by-row or item-by-item.

For example, if close is a 1-d array, and you want the day-over-day percent change,

pct_change = close[1:]/close[:-1]

This computes the entire array of percent changes as one statement, instead of

pct_change = []
for row in close:
    pct_change.append(...)

So try to avoid the Python loop for i, row in enumerate(...) entirely, and think about how to perform your calculations with operations on the entire array (or dataframe) as a whole, rather than row-by-row.

Comparison expressions should each be in their own brackets:

{% if (a == 'foo') or (b == 'bar') %}
    ...
{% endif %}

Alternative if you are inspecting a single variable and a number of possible values:

{% if a in ['foo', 'bar', 'qux'] %}
    ...
{% endif %}

Very late to the game, but this is a version of Chris Pratt's answer that protects against race conditions while sacrificing performance, by using a transaction block and select_for_update()

@receiver(pre_save, sender=MyModel)
@transaction.atomic
def do_something_if_changed(sender, instance, **kwargs):
    try:
        obj = sender.objects.select_for_update().get(pk=instance.pk)
    except sender.DoesNotExist:
        pass # Object is new, so field hasn't technically changed, but you may want to do something else here.
    else:
        if not obj.some_field == instance.some_field: # Field has changed
            # do something

Use this

 from tensorflow.keras.datasets import imdb

instead of this

Amazon EC2 instances are just virtual machines so you would setup SSL the same way you would set it up on any server.

You don't mention what platform you are on, so it difficult to give any more information.

Try this:

System.Configuration.ConfigurationFileMap fileMap = new ConfigurationFileMap(strConfigPath); //Path to your config file
System.Configuration.Configuration configuration = System.Configuration.ConfigurationManager.OpenMappedMachineConfiguration(fileMap);

SELECT StoreId
FROM StoreClients
WHERE StoreId NOT IN (
  SELECT StoreId

SQL Fiddle

@Bruno Lavit has a great answer, but if you want you can just access the log and download it as txt file to your workspace from the job's URL:

${BUILD_URL}/consoleText

Then it's only a matter of downloading this page to your ${Workspace}

• You can use "Invoke ANT" and use the GET target
• On Linux you can use wget to download it to your workspace
• etc.

Good luck!

Edit: The actual log file on the file system is not on the slave, but kept in the Master machine. You can find it under: $JENKINS_HOME/jobs/$JOB_NAME/builds/lastSuccessfulBuild/log

If you're looking for another build just replace lastSuccessfulBuild with the build you're looking for.

You can also do this without using jQuery. Override XMLHttpRequest's send method and add the header there:

XMLHttpRequest.prototype.realSend = XMLHttpRequest.prototype.send;
var newSend = function(vData) {
    this.setRequestHeader('x-my-custom-header', 'some value');
    this.realSend(vData);
};
XMLHttpRequest.prototype.send = newSend;

This might be useful. It allows "real" numeric values, including proper decimal points and preceding plus or minus signs. Call it from within the related KeyPress event.

        // may indeed be placed at the current insertion position.
        return true;
    }

Loops can be broken using custom conditions in the loop, allowing as to have clean code.

    static void Main(string[] args)
    {
        bool isBreak = false;
        for (int i = 0; ConditionLoop(isBreak, i, 500); i++)
        {
            Console.WriteLine($"External loop iteration {i}");
            for (int j = 0; ConditionLoop(isBreak, j, 500); j++)
            {
                Console.WriteLine($"Inner loop iteration {j}");

                // This code is only to produce the break.
                if (j > 3)
                {
                    isBreak = true;
                }                  
            }

            Console.WriteLine("The code after the inner loop will be executed when breaks");
        }

        Console.ReadKey();
    }

    private static bool ConditionLoop(bool isBreak, int i, int maxIterations) => i < maxIterations && !isBreak;   

With this code we ontain the following output:

• External loop iteration 0
• Inner loop iteration 0
• Inner loop iteration 1
• Inner loop iteration 2
• Inner loop iteration 3
• Inner loop iteration 4
• The code after the inner loop will be executed when breaks

It depends at least on the version of PHP that is used. wp-includes/class-phpass.php contains all the answers.

I faced the same problem (ORA-01000) today. I had a for loop in the try{}, to execute a SELECT statement in an Oracle DB many times, (each time changing a parameter), and in the finally{} I had my code to close Resultset, PreparedStatement and Connection as usual. But as soon as I reached a specific amount of loops (1000) I got the Oracle error about too many open cursors.

Based on the post by Andrew Alcock above, I made changes so that inside the loop, I closed each resultset and each statement after getting the data and before looping again, and that solved the problem.

Additionaly, the exact same problem occured in another loop of Insert Statements, in another Oracle DB (ORA-01000), this time after 300 statements. Again it was solved in the same way, so either the PreparedStatement or the ResultSet or both, count as open cursors until they are closed.

You just need to enter this command:

sudo apt-get install gcc

Instead of "right click"....start your session (once you're in the command prompt window) by keying Alt/SpaceBar. That will open the Command Prompt window menu and you'll see your familiar, underlined keyboard command shortcuts, just like in Windows GUI.

Good luck!

There isn't much else to add other than what the docs say. If you want to dump the JSON into a file/socket or whatever, then you should go with dump(). If you only need it as a string (for printing, parsing or whatever) then use dumps() (dump string)

As mentioned by Antti Haapala in this answer, there are some minor differences on the ensure_ascii behaviour. This is mostly due to how the underlying write() function works, being that it operates on chunks rather than the whole string. Check his answer for more details on that.

json.dump()

Serialize obj as a JSON formatted stream to fp (a .write()-supporting file-like object

If ensure_ascii is False, some chunks written to fp may be unicode instances

json.dumps()

Serialize obj to a JSON formatted str

If ensure_ascii is False, the result may contain non-ASCII characters and the return value may be a unicode instance

Send the following headers before outputting the file:

header("Content-Disposition: attachment; filename=\"" . basename($File) . "\"");
header("Content-Type: application/octet-stream");
header("Content-Length: " . filesize($File));
header("Connection: close");

@grom: Interesting about the 'application/octet-stream' MIME type. I wasn't aware of that, have always just used 'application/force-download' :)

You can use javac *.java command to compile all you java sources. Also you should learn a little about classpath because it seems that you should set appropriate classpath for succesful compilation (because your IDE use some libraries for building WebService clients). Also I can recommend you to check wich command your IDE use to build your project.

It's possible that your WCF service is returning HTML. In this case, you'll want to set up a binding on the service side to return XML instead. However, this is unlikely: if it is the case, let me know and I'll make an edit with more details.

The more likely reason is that your service is throwing an error, which is returning an HTML error page. You can take a look at this blog post if you want details.

tl;dr: There are a few possible configurations for error pages. If you're hosting on IIS, you'll want to remove the <httpErrors> section from the WCF service's web.config file. If not, please provide details of your service hosting scenario and I can come up with an edit to match them.

EDIT:

Having seen your edit, you can see the full error being returned. Apache can't tell which service you want to call, and is throwing an error for that reason. The service will work fine once you have the correct endpoint - you're pointed at the wrong location. I unfortunately can't tell from the information available what the right location is, but either your action (currently null!) or the URL is incorrect.

had better be List

The only List implementation in java.util.concurrent is CopyOnWriteArrayList. There's also the option of a synchronized list as Travis Webb mentions.

That said, are you sure you need it to be a List? There are a lot more options for concurrent Queues and Maps (and you can make Sets from Maps), and those structures tend to make the most sense for many of the types of things you want to do with a shared data structure.

For queues, you have a huge number of options and which is most appropriate depends on how you need to use it:

• ConcurrentLinkedQueue
• ArrayBlockingQueue
• LinkedBlockingDeque
• LinkedBlockingQueue
• PriorityBlockingQueue
• SynchronousQueue
• DelayQueue

Why use SurfaceView and not the classic View class...

One main reason is that SurfaceView can rapidly render the screen.

In simple words a SV is more capable of managing the timing and render animations.

To have a better understanding what is a SurfaceView we must compare it with the View class.

What is the difference... check this simple explanation in the video

https://m.youtube.com/watch?feature=youtu.be&v=eltlqsHSG30

Well with the View we have one major problem....the timing of rendering animations.

Normally the onDraw() is called from the Android run-time system.

So, when Android run-time system calls onDraw() then the application cant control

the timing of display, and this is important for animation. We have a gap of timing

between the application (our game) and the Android run-time system.

The SV it can call the onDraw() by a dedicated Thread.

Thus: the application controls the timing. So we can display the next bitmap image of the animation.

collections.defaultdict can be sub-classed to make a nested dict. Then add any useful iteration methods to that class.

>>> from collections import defaultdict
>>> class nesteddict(defaultdict):
    def __init__(self):
        defaultdict.__init__(self, nesteddict)
    def walk(self):
        for key, value in self.iteritems():
            if isinstance(value, nesteddict):
                for tup in value.walk():
                    yield (key,) + tup
            else:
                yield key, value


>>> nd = nesteddict()
>>> nd['new jersey']['mercer county']['plumbers'] = 3
>>> nd['new jersey']['mercer county']['programmers'] = 81
>>> nd['new jersey']['middlesex county']['programmers'] = 81
>>> nd['new jersey']['middlesex county']['salesmen'] = 62
>>> nd['new york']['queens county']['plumbers'] = 9
>>> nd['new york']['queens county']['salesmen'] = 36
>>> for tup in nd.walk():
    print tup


('new jersey', 'mercer county', 'programmers', 81)

The URL structure you're referring to is called the REST endpoint, as opposed to the Web Site Endpoint.

Note: Since this answer was originally written, S3 has rolled out dualstack support on REST endpoints, using new hostnames, while leaving the existing hostnames in place. This is now integrated into the information provided, below.

If your bucket is really in the us-east-1 region of AWS -- which the S3 documentation formerly referred to as the "US Standard" region, but was subsequently officially renamed to the "U.S. East (N. Virginia) Region" -- then http://s3-us-east-1.amazonaws.com/bucket/ is not the correct form for that endpoint, even though it looks like it should be. The correct format for that region is either http://s3.amazonaws.com/bucket/ or http://s3-external-1.amazonaws.com/bucket/.¹

The format you're using is applicable to all the other S3 regions, but not US Standard US East (N. Virginia) [us-east-1].

S3 now also has dual-stack endpoint hostnames for the REST endpoints, and unlike the original endpoint hostnames, the names of these have a consistent format across regions, for example s3.dualstack.us-east-1.amazonaws.com. These endpoints support both IPv4 and IPv6 connectivity and DNS resolution, but are otherwise functionally equivalent to the existing REST endpoints.

If your permissions and configuration are set up such that the web site endpoint works, then the REST endpoint should work, too.

However... the two endpoints do not offer the same functionality.

Roughly speaking, the REST endpoint is better-suited for machine access and the web site endpoint is better suited for human access, since the web site endpoint offers friendly error messages, index documents, and redirects, while the REST endpoint doesn't. On the other hand, the REST endpoint offers HTTPS and support for signed URLs, while the web site endpoint doesn't.

Choose the correct type of endpoint (REST or web site) for your application:

http://docs.aws.amazon.com/AmazonS3/latest/dev/WebsiteEndpoints.html#WebsiteRestEndpointDiff

¹ s3-external-1.amazonaws.com has been referred to as the "Northern Virginia endpoint," in contrast to the "Global endpoint" s3.amazonaws.com. It was unofficially possible to get read-after-write consistency on new objects in this region if the "s3-external-1" hostname was used, because this would send you to a subset of possible physical endpoints that could provide that functionality. This behavior is now officially supported on this endpoint, so this is probably the better choice in many applications. Previously, s3-external-2 had been referred to as the "Pacific Northwest endpoint" for US-Standard, though it is now a CNAME in DNS for s3-external-1 so s3-external-2 appears to have no purpose except backwards-compatibility.

Also it's worth knowing that you may need to include .\ in front of the script name. For example:

.\scriptname.ps1

I'm using a simplyfied version (just using position relative) based on @SimonEast answer:

li:before {
    content: "\e080";
    font-family: 'Glyphicons Halflings';
    font-size: 9px;
    position: relative;
    margin-right: 10px;
    top: 3px;
    color: #ccc;
}

Never mind, I found it in the source: base.git/core/res/res and subdirectories.

As others said in the comments, if you have the Android SDK installed it’s also on your computer. The path is [SDK]/platforms/android-[VERSION]/data/res.

You could use String.Split method.

class ExampleClass
{
    public ExampleClass()
    {
        string exampleString = "there is a cat";
        // Split string on spaces. This will separate all the words in a string
        string[] words = exampleString.Split(' ');
        foreach (string word in words)
        {
            Console.WriteLine(word);
            // there
            // is
            // a
            // cat
        }
    }
}

For more information see Sam Allen's article about splitting strings in c# (Performance, Regex)

That's the non-null assertion operator. It is a way to tell the compiler "this expression cannot be null or undefined here, so don't complain about the possibility of it being null or undefined." Sometimes the type checker is unable to make that determination itself.

It is explained here:

A new ! post-fix expression operator may be used to assert that its operand is non-null and non-undefined in contexts where the type checker is unable to conclude that fact. Specifically, the operation x! produces a value of the type of x with null and undefined excluded. Similar to type assertions of the forms <T>x and x as T, the ! non-null assertion operator is simply removed in the emitted JavaScript code.

I find the use of the term "assert" a bit misleading in that explanation. It is "assert" in the sense that the developer is asserting it, not in the sense that a test is going to be performed. The last line indeed indicates that it results in no JavaScript code being emitted.

Use: Path.GetFileName Method

var onlyFileName = System.IO.Path.GetFileName(ofd.FileName);

Set is used for setting object references, as opposed to assigning a value.

The easiest way to freeze the UI would be to make the AJAX call synchronous.

Usually synchronous AJAX calls defeat the purpose of using AJAX because it freezes the UI, but if you want to prevent the user from interacting with the UI, then do it.

Array.forEach does not provide this nicety (oh if it would) but there are several ways to accomplish what you want:

Using a simple counter

function callback () { console.log('all done'); }

var itemsProcessed = 0;

[1, 2, 3].forEach((item, index, array) => {
  asyncFunction(item, () => {
    itemsProcessed++;
    if(itemsProcessed === array.length) {
      callback();
    }
  });
});

(thanks to @vanuan and others) This approach guarantees that all items are processed before invoking the "done" callback. You need to use a counter that gets updated in the callback. Depending on the value of the index parameter does not provide the same guarantee, because the order of return of the asynchronous operations is not guaranteed.

Using ES6 Promises

(a promise library can be used for older browsers):

1. Process all requests guaranteeing synchronous execution (e.g. 1 then 2 then 3)

   function asyncFunction (item, cb) {
     setTimeout(() => {
       console.log('done with', item);
       cb();
     }, 100);
   }
   
   let requests = [1, 2, 3].reduce((promiseChain, item) => {
       return promiseChain.then(() => new Promise((resolve) => {
         asyncFunction(item, resolve);
       }));
   }, Promise.resolve());
   
   requests.then(() => console.log('done'))
   

2. Process all async requests without "synchronous" execution (2 may finish faster than 1)

   let requests = [1,2,3].map((item) => {
       return new Promise((resolve) => {
         asyncFunction(item, resolve);
       });
   })
   
   Promise.all(requests).then(() => console.log('done'));
   

Using an async library

There are other asynchronous libraries, async being the most popular, that provide mechanisms to express what you want.

The body of the question has been edited to remove the previously synchronous example code, so i've updated my answer to clarify. The original example used synchronous like code to model asynchronous behaviour, so the following applied:

array.forEach is synchronous and so is res.write, so you can simply put your callback after your call to foreach:

  posts.foreach(function(v, i) {
    res.write(v + ". index " + i);
  });

  res.end();

I tested as follows:

import numpy as np, datetime
# array of zeros and ones interleaved
lrg = np.arange(2).reshape((2,-1)).repeat(1000000,-1).flatten()

t0 = datetime.datetime.now()
flt = lrg[lrg==0]
print datetime.datetime.now() - t0

t0 = datetime.datetime.now()
flt = np.array(filter(lambda x:x==0, lrg))
print datetime.datetime.now() - t0

I got

$ python test.py

}

If the variable ax.xaxis._autolabelpos = True, matplotlib sets the label position in function _update_label_position in axis.py according to (some excerpts):

    bboxes, bboxes2 = self._get_tick_bboxes(ticks_to_draw, renderer)
    bbox = mtransforms.Bbox.union(bboxes)
    bottom = bbox.y0
    x, y = self.label.get_position()
    self.label.set_position((x, bottom - self.labelpad * self.figure.dpi / 72.0))

You can set the label position independently of the ticks by using:

    ax.xaxis.set_label_coords(x0, y0)

that sets _autolabelpos to False or as mentioned above by changing the labelpad parameter.

After evaluating i++ or ++i, the new value of i will be the same in both cases. The difference between pre- and post-increment is in the result of evaluating the expression itself.

++i increments i and evaluates to the new value of i.

i++ evaluates to the old value of i, and increments i.

The reason this doesn't matter in a for loop is that the flow of control works roughly like this:

1. test the condition
2. if it is false, terminate
3. if it is true, execute the body
4. execute the incrementation step

Because (1) and (4) are decoupled, either pre- or post-increment can be used.

You could query an LDAP server from the command line with ldap-utils: ldapsearch, ldapadd, ldapmodify

Follow the following steps:

1. Output the object with console.log from your code, like so: console.log(myObject)
2. Right click on the object and click "Store as Global Object". Chrome would print the name of the variable at this point. Let's assume it's called "temp1".
3. In the console, type: JSON.stringify(temp1).
4. At this point you will see the entire JSON object as a string that you can copy/paste.
5. You can use online tools like http://www.jsoneditoronline.org/ to prettify your string at this point.

This can also get the filename

The method you are looking for is jQuery's .text() and you can used it in the following fashion:

$('#a_tbnotesverbergen').text('text here');

According to this JSPerf test, they differ in speed. But unless you're going to use them in huge amounts, any of them should perform fine.

For completeness: As asawyer already mentioned, you can also use the .toString() method.

In Docker release v1.0, binding a mount of a file or directory on the host machine can be done by the given command:

I see this is a fairly old question, but this looks like one of those times when something's been written without knowledge of a language feature. The collections library exists to fulfill these purposes.

from collections import Counter
letter_counter = Counter()
for letter in 'The quick brown fox jumps over the lazy dog':
    letter_counter[letter] += 1

>>> letter_counter
Counter({' ': 8, 'o': 4, 'e': 3, 'h': 2, 'r': 2, 'u': 2, 'T': 1, 'a': 1, 'c': 1, 'b': 1, 'd': 1, 'g': 1, 'f': 1, 'i': 1, 'k': 1, 'j': 1, 'm': 1, 'l': 1, 'n': 1, 'q': 1, 'p': 1, 's': 1, 't': 1, 'w': 1, 'v': 1, 'y': 1, 'x': 1, 'z': 1})

In this example the spaces are being counted, obviously, but whether or not you want those filtered is up to you.

As for the dict.get(a_key, default_value), there have been several answers to this particular question -- this method returns the value of the key, or the default_value you supply. The first argument is the key you're looking for, the second argument is the default for when that key is not present.

I generally use Date if possible. Although it is mutable, the mutators are actually deprecated. In the end it basically wraps a long that would represent the date/time. Conversely, I would use Calendars if I have to manipulate the values.

You can think of it this way: you only use StringBuffer only when you need to have Strings that you can easily manipulate and then convert them into Strings using toString() method. In the same way, I only use Calendar if I need to manipulate temporal data.

For best practice, I tend to use immutable objects as much as possible outside of the domain model. It significantly reduces the chances of any side effects and it is done for you by the compiler, rather than a JUnit test. You use this technique by creating private final fields in your class.

And coming back to the StringBuffer analogy. Here is some code that shows you how to convert between Calendar and Date

String s = "someString"; // immutable string
StringBuffer buf = new StringBuffer(s); // mutable "string" via StringBuffer
buf.append("x");
assertEquals("someStringx", buf.toString()); // convert to immutable String

// immutable date with hard coded format.  If you are hard
// coding the format, best practice is to hard code the locale
// of the format string, otherwise people in some parts of Europe
// are going to be mad at you.
Date date =     new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH).parse("2001-01-02");

// Convert Date to a Calendar
Calendar cal = Calendar.getInstance();
cal.setTime(date);

// mutate the value
cal.add(Calendar.YEAR, 1);

// convert back to Date
Date newDate = cal.getTime();

// 
assertEquals(new SimpleDateFormat("yyyy-MM-dd", Locale.ENGLISH).parse("2002-01-02"), newDate);

Another method that can be used to copy tables from the source database to the destination one is the SQL Server Export and Import wizard, which is available in SQL Server Management Studio.

You have the choice to export from the source database or import from the destination one in order to transfer the data.

This method is a quick way to copy tables from the source database to the destination one, if you arrange to copy tables having no concern with the tables’ relationships and orders.

When using this method, the tables’ indexes and keys will not be transferred. If you are interested in copying it, you need to generate scripts for these database objects.

If these are Foreign Keys, connecting these tables together, you need to export the data in the correct order, otherwise the export wizard will fail.

Feel free to read more about this method, as well as about some more methods (including generate scripts, SELECT INTO and third party tools) in this article: https://www.sqlshack.com/how-to-copy-tables-from-one-database-to-another-in-sql-server/

A simple method by using for loop :

import os

dir = ["e","x","e"]

p = os.listdir('E:')  #path

for n in range(len(p)):
   name = p[n]
   myfile = [name[-3],name[-2],name[-1]]  #for .txt
   if myfile == dir :
      print(name)
   else:
      print("nops")

Though this can be made more generalised .

If you're on Django 1.10 or newer AND Postgres as your database, you can use ArrayField. It's better to use than django-taggit or other alternatives, as it's native to the Django framework. https://docs.djangoproject.com/en/3.1/ref/contrib/postgres/fields/#arrayfield

from django.db import models
from django.contrib.postgres.fields import ArrayField

class ChessBoard(models.Model):
    board = ArrayField(
        ArrayField(
            models.CharField(max_length=10, blank=True),
            size=8,
        ),
        size=8,
    )

If you're on Django 3.1 or newer they've added support for JSONField with most database backends (MariaDB 10.2.7+, MySQL 5.7.8+, Oracle, PostgreSQL, and SQLite 3.9.0+). You can use this to store your Array!

https://docs.djangoproject.com/en/3.1/ref/models/fields/#jsonfield

from django.db import models

class ChessBoard(models.Model):
    list_of_pieces = models.JSONField()

If you simply want to squash all commits into a single, initial commit, just reset the repository and amend the first commit:

git reset hash-of-first-commit
git add -A
git commit --amend

Git reset will leave the working tree intact, so everything is still there. So just add the files using git add commands, and amend the first commit with these changes. Compared to rebase -i you'll lose the ability to merge the git comments though.

if (date.isBefore(endDate) 
 && date.isAfter(startDate) 
 || (date.isSame(startDate) || date.isSame(endDate))

is logically the same as

if (!(date.isBefore(startDate) || date.isAfter(endDate)))

which saves you a couple of lines of code and (in some cases) method calls.

Might be easier than pulling in a whole plugin if you only want to do this once or twice.

Building on some of the answers here and elsewhere, I've written this simple function which displays a progress bar and elapsed/estimated remaining time. Should work on most unix-based machines.

import time
import sys

percent = 50.0
start = time.time()
draw_progress_bar(percent, start)


def draw_progress_bar(percent, start, barLen=20):
sys.stdout.write("\r")
progress = ""
for i in range(barLen):
    if i < int(barLen * percent):
        progress += "="
    else:
        progress += " "

elapsedTime = time.time() - start;
estimatedRemaining = int(elapsedTime * (1.0/percent) - elapsedTime)

if (percent == 1.0):
    sys.stdout.write("[ %s ] %.1f%% Elapsed: %im %02is ETA: Done!\n" % 
        (progress, percent * 100, int(elapsedTime)/60, int(elapsedTime)%60))
    sys.stdout.flush()
    return
else:
    sys.stdout.write("[ %s ] %.1f%% Elapsed: %im %02is ETA: %im%02is " % 
        (progress, percent * 100, int(elapsedTime)/60, int(elapsedTime)%60,
         estimatedRemaining/60, estimatedRemaining%60))
    sys.stdout.flush()
    return

If you've added your own custom configuration sections to your App.Config, make sure you have defined the section in the <configSections> element. I added the my config XML but forgot to declare the configuration section up top - which caused the exception "Configuration system failed to initialize" for me.

In a follow-up answer, you asked about the relative performance of these two alternatives:

z1 = dict(x.items() + y.items())
z2 = dict(x, **y)

On my machine, at least (a fairly ordinary x86_64 running Python 2.5.2), alternative z2 is not only shorter and simpler but also significantly faster. You can verify this for yourself using the timeit module that comes with Python.

Example 1: identical dictionaries mapping 20 consecutive integers to themselves:

% python -m timeit -s 'x=y=dict((i,i) for i in range(20))' 'z1=dict(x.items() + y.items())'
100000 loops, best of 3: 5.67 usec per loop
% python -m timeit -s 'x=y=dict((i,i) for i in range(20))' 'z2=dict(x, **y)' 
100000 loops, best of 3: 1.53 usec per loop

z2 wins by a factor of 3.5 or so. Different dictionaries seem to yield quite different results, but z2 always seems to come out ahead. (If you get inconsistent results for the same test, try passing in -r with a number larger than the default 3.)

Example 2: non-overlapping dictionaries mapping 252 short strings to integers and vice versa:

% python -m timeit -s 'from htmlentitydefs import codepoint2name as x, name2codepoint as y' 'z1=dict(x.items() + y.items())'
1000 loops, best of 3: 260 usec per loop
% python -m timeit -s 'from htmlentitydefs import codepoint2name as x, name2codepoint as y' 'z2=dict(x, **y)'               
10000 loops, best of 3: 26.9 usec per loop

z2 wins by about a factor of 10. That's a pretty big win in my book!

After comparing those two, I wondered if z1's poor performance could be attributed to the overhead of constructing the two item lists, which in turn led me to wonder if this variation might work better:

from itertools import chain
z3 = dict(chain(x.iteritems(), y.iteritems()))

A few quick tests, e.g.

% python -m timeit -s 'from itertools import chain; from htmlentitydefs import codepoint2name as x, name2codepoint as y' 'z3=dict(chain(x.iteritems(), y.iteritems()))'
10000 loops, best of 3: 66 usec per loop

lead me to conclude that z3 is somewhat faster than z1, but not nearly as fast as z2. Definitely not worth all the extra typing.

This discussion is still missing something important, which is a performance comparison of these alternatives with the "obvious" way of merging two lists: using the update method. To try to keep things on an equal footing with the expressions, none of which modify x or y, I'm going to make a copy of x instead of modifying it in-place, as follows:

z0 = dict(x)
z0.update(y)

A typical result:

% python -m timeit -s 'from htmlentitydefs import codepoint2name as x, name2codepoint as y' 'z0=dict(x); z0.update(y)'
10000 loops, best of 3: 26.9 usec per loop

In other words, z0 and z2 seem to have essentially identical performance. Do you think this might be a coincidence? I don't....

In fact, I'd go so far as to claim that it's impossible for pure Python code to do any better than this. And if you can do significantly better in a C extension module, I imagine the Python folks might well be interested in incorporating your code (or a variation on your approach) into the Python core. Python uses dict in lots of places; optimizing its operations is a big deal.

You could also write this as

z0 = x.copy()
z0.update(y)

as Tony does, but (not surprisingly) the difference in notation turns out not to have any measurable effect on performance. Use whichever looks right to you. Of course, he's absolutely correct to point out that the two-statement version is much easier to understand.

I extended @Ben Lesh's answer with an ability to specify whether the validation is case sensitive or not (default)

use:

<input type="text" name="fruitName" ng-model="data.fruitName" blacklist="Coconuts,Bananas,Pears" caseSensitive="true" required/>

code:

angular.module('crm.directives', []).
directive('blacklist', [
    function () {
        return {
            restrict: 'A',
            require: 'ngModel',
            scope: {
                'blacklist': '=',
            },
            link: function ($scope, $elem, $attrs, modelCtrl) {

                var check = function (value) {
                    if (!$attrs.casesensitive) {
                        value = (value && value.toUpperCase) ? value.toUpperCase() : value;

                        $scope.blacklist = _.map($scope.blacklist, function (item) {
                            return (item.toUpperCase) ? item.toUpperCase() : item
                        })
                    }

                    return !_.isArray($scope.blacklist) || $scope.blacklist.indexOf(value) === -1;
                }

                //For DOM -> model validation
                modelCtrl.$parsers.unshift(function (value) {
                    var valid = check(value);
                    modelCtrl.$setValidity('blacklist', valid);

                    return value;
                });
                //For model -> DOM validation
                modelCtrl.$formatters.unshift(function (value) {
                    modelCtrl.$setValidity('blacklist', check(value));
                    return value;
                });
            }
        };
    }
]);

To extract the real part of a complex-valued expression z, use the notation as __real__ z. Similarly, use __imag__ attribute on the z to extract the imaginary part.

For example;

__complex__ float z;
float r;
float i;
r = __real__ z;
i = __imag__ z;

r is the real part of the complex number "z" i is the imaginary part of the complex number "z"

You're deleting the row from the gridview and then rebinding it to the datasource (which still contains the row). Either delete the row from the datasource, or don't rebind the gridview afterwards.

I had the same error message. In my case, Jackson consisted of multiple JAR files. Sadly, they had different versions of jackson-core and jackson-annotations which resulted in the above exception.

Maybe you don't have the jackson-annotation JAR in your classpath, at least not in the correct version. You can analyze the used library versions with the command mvn dependency:tree.

Looking at the JDK, innermost constructor for Calendar.getInstance() has this:

public GregorianCalendar(TimeZone zone, Locale aLocale) {
    super(zone, aLocale);
    gdate = (BaseCalendar.Date) gcal.newCalendarDate(zone);
    setTimeInMillis(System.currentTimeMillis());
}

so it already automatically does what you suggest. Date's default constructor holds this:

public Date() {
    this(System.currentTimeMillis());
}

So there really isn't need to get system time specifically unless you want to do some math with it before creating your Calendar/Date object with it. Also I do have to recommend joda-time to use as replacement for Java's own calendar/date classes if your purpose is to work with date calculations a lot.

You can use exit method to quit an ios app :

exit(0);

You should say same alert message and ask him to quit

Another way is by using [[NSThread mainThread] exit]

However you should not do this way

According to Apple, your app should not terminate on its own. Since the user did not hit the Home button, any return to the Home screen gives the user the impression that your app crashed. This is confusing, non-standard behavior and should be avoided.

I had no luck getting tar to exclude a 5 Gigabyte subdirectory a few levels deep. In the end, I just used the unix Zip command. It worked a lot easier for me.

So for this particular example from the original post
(tar --exclude='./folder' --exclude='./upload/folder2' -zcvf /backup/filename.tgz . )

The equivalent would be:

zip -r /backup/filename.zip . -x upload/folder/**\* upload/folder2/**\*

(NOTE: Here is the post I originally used that helped me https://superuser.com/questions/312301/unix-zip-directory-but-excluded-specific-subdirectories-and-everything-within-t)

I was having the same error, but had a proper connection string. My problem was that the driver was not being used, therefore was optimized out of the compiled war.

Be sure to import the driver:

import com.microsoft.sqlserver.jdbc.SQLServerDriver;

And then to force it to be included in the final war, you can do something like this:

Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");

That line is in the original question. This will also work:

SQLServerDriver driver = new SQLServerDriver();

I did the following:

void BrowserDocumentCompleted(object sender,
        WebBrowserDocumentCompletedEventArgs e)
{
  if (e.Url.AbsolutePath != (sender as WebBrowser).Url.AbsolutePath)
    return; 

  //The page is finished loading 
}

The last page loaded tends to be the one navigated to, so this should work.

From here.

tl;dr What to do in modern (2018) times? Assume tel: is supported, use it and forget about anything else.

The tel: URI scheme RFC5431 (as well as sms: but also feed:, maps:, youtube: and others) is handled by protocol handlers (as mailto: and http: are).

They're unrelated to HTML5 specification (it has been out there from 90s and documented first time back in 2k with RFC2806) then you can't check for their support using tools as modernizr. A protocol handler may be installed by an application (for example Skype installs a callto: protocol handler with same meaning and behaviour of tel: but it's not a standard), natively supported by browser or installed (with some limitations) by website itself.

What HTML5 added is support for installing custom web based protocol handlers (with registerProtocolHandler() and related functions) simplifying also the check for their support through isProtocolHandlerRegistered() function.

There is some easy ways to determine if there is an handler or not:" How to detect browser's protocol handlers?).

In general what I suggest is:

1. If you're running on a mobile device then you can safely assume tel: is supported (yes, it's not true for very old devices but IMO you can ignore them).
2. If JS isn't active then do nothing.
3. If you're running on desktop browsers then you can use one of the techniques in the linked post to determine if it's supported.
4. If tel: isn't supported then change links to use callto: and repeat check desctibed in 3.
5. If tel: and callto: aren't supported (or - in a desktop browser - you can't detect their support) then simply remove that link replacing URL in href with javascript:void(0) and (if number isn't repeated in text span) putting, telephone number in title. Here HTML5 microdata won't help users (just search engines). Note that newer versions of Skype handle both callto: and tel:.

Please note that (at least on latest Windows versions) there is always a - fake - registered protocol handler called App Picker (that annoying window that let you choose with which application you want to open an unknown file). This may vanish your tests so if you don't want to handle Windows environment as a special case you can simplify this process as:

1. If you're running on a mobile device then assume tel: is supported.
2. If you're running on desktop then replace tel: with callto:. then drop tel: or leave it as is (assuming there are good chances Skype is installed).

Here's what I do in these situations. It's a kludge but it works just fine for me.

1. Create another branch based off of your working branch.
2. git pull/git merge the revision (SHA1) which contains the file you want to copy. So this will merge all of your changes, but we are only using this branch to grab the one file.
3. Fix up any Conflicts etc. investigate your file.
4. checkout your working branch
5. Checkout the file commited from your merge.
6. Commit it.

I tried patching and my situation was too ugly for it. So in short it would look like this:

Working Branch: A Experimental Branch: B (contains file.txt which has changes I want to fold in.)

git checkout A

Create new branch based on A:

git checkout -b tempAB

Merge B into tempAB

git merge B

Copy the sha1 hash of the merge:

git log

commit 8dad944210dfb901695975886737dc35614fa94e
Merge: ea3aec1 0f76e61
Author: matthewe <[email protected]>
Date:   Wed Oct 3 15:13:24 2012 -0700

Merge branch 'B' into tempAB

Checkout your working branch:

git checkout A

Checkout your fixed-up file:

git checkout 7e65b5a52e5f8b1979d75dffbbe4f7ee7dad5017 file.txt

And there you should have it. Commit your result.

I have found one difference, for ES6/ES2015. You cannot return an object using the shorthand arrow function syntax, unless you surround the object with new Object().

> [1, 2, 3].map(v => {n: v});
[ undefined, undefined, undefined ]
> [1, 2, 3].map(v => new Object({n: v}));
[ { n: 1 }, { n: 2 }, { n: 3 } ]

This is because the compiler is confused by the {} brackets and thinks n: i is a label: statement construct; the semicolon is optional so it doesn't complain about it.

If you add another property to the object it will finally throw an error.

$ node -e "[1, 2, 3].map(v => {n: v, m: v+1});"
[1, 2, 3].map(v => {n: v, m: v+1});
                           ^

SyntaxError: Unexpected token :

You can use WEBRTC but unfortunately it is not supported by all web browsers. BELOW IS THE LINK TO SHOW WHICH BROWSERS supports it http://caniuse.com/stream

And this link gives you an idea of how you can access it(sample code). http://www.html5rocks.com/en/tutorials/getusermedia/intro/

the repr function will return a string which is the exact definition of your dict (except for the order of the element, dicts are unordered in python). unfortunately, i can't tell a way to automatically get a string which represent the variable name.

>>> dict = {'one': 1, 'two': 2}
>>> repr(dict)
"{'two': 2, 'one': 1}"

writing to a file is pretty standard stuff, like any other file write:

f = open( 'file.py', 'w' )
f.write( 'dict = ' + repr(dict) + '\n' )
f.close()

Use the walklevel function.

import os

def walklevel(some_dir, level=1):
    some_dir = some_dir.rstrip(os.path.sep)
    assert os.path.isdir(some_dir)
    num_sep = some_dir.count(os.path.sep)
    for root, dirs, files in os.walk(some_dir):
        yield root, dirs, files
        num_sep_this = root.count(os.path.sep)
        if num_sep + level <= num_sep_this:
            del dirs[:]

It works just like os.walk, but you can pass it a level parameter that indicates how deep the recursion will go.

Well it depends on what you have in your table.

its one of the following If you have only one table

var count = $('#gvPerformanceResult tr').length;

If you are concerned about sub tables but this wont work with tbody and thead (if you use them)

var count = $('#gvPerformanceResult>tr').length;

Where by this will work (but is quite frankly overkill.)

var count = $('#gvPerformanceResult>tbody>tr').length;

If you're trying to print a specific register in GDB, you have to omit the % sign. For example,

info registers eip

If your executable is 64 bit, the registers start with r. Starting them with e is not valid.

info registers rip

Those can be abbreviated to:

i r rip

Another way to resolve this problem is:

Let's assume:

path_to_driver_directory = C:\Work\drivers\

driver = IEDriverServer.exe

When getting messsage about path you can always add path_to_driver_directory containing driver to the PATH environment variable. Check: http://java.com/en/download/help/path.xml

Then simply check in cmd window if driver is available - just run cmd in any location and type name of driver.

If everything works fine then you get:

C:\Users\A>IEDriverServer.exe
Started InternetExplorerDriver server (32-bit)
2.28.0.0
Listening on port 5555

Thats it.

I think your problem is inside CheckCircular, in the while condition:

Assume you have 2 nodes, first N1 and N2 point to the same node, then N1 points to the second node (last) and N2 points to null (because it's N2.next.next). In the next loop, you try to call the 'next' method on N2, but N2 is null. There you have it, NullPointerException

If you don't wish to make many changes, then you could just put:

android:layout_weight="1"

for the TextView having ID as @+id/TextView i.e

<TextView android:text="@string/welcome" 
    android:id="@+id/TextView" 
    android:layout_width="fill_parent" 
    android:layout_height="wrap_content"
    android:layout_weight="1">
</TextView>

In your Main method, you're trying to access, for instance, club (which is protected), when you should be accessing myclub which is the public property that you created.

Yes you can use CASE

UPDATE table 
SET columnB = CASE fieldA 
        WHEN columnA=1 THEN 'x' 
        WHEN columnA=2 THEN 'y' 
        ELSE 'z' 
      END 
WHERE columnC = 1

When speaking with remote machines, Ansible by default assumes you are using SSH keys. SSH keys are encouraged but password authentication can also be used where needed by supplying the option --ask-pass. If using sudo features and when sudo requires a password, also supply --ask-become-pass (previously --ask-sudo-pass which has been deprecated).

Never used the feature but the docs say you can.

The reason for this is, that Google is sending an "X-Frame-Options: SAMEORIGIN" response header. This option prevents the browser from displaying iFrames that are not hosted on the same domain as the parent page.

See: Mozilla Developer Network - The X-Frame-Options response header

Two ways:

1. Implement ActionListener in your class, then use jBtnSelection.addActionListener(this); Later, you'll have to define a menthod, public void actionPerformed(ActionEvent e). However, doing this for multiple buttons can be confusing, because the actionPerformed method will have to check the source of each event (e.getSource()) to see which button it came from.

2. Use anonymous inner classes:

jBtnSelection.addActionListener(new ActionListener() { 
  public void actionPerformed(ActionEvent e) { 
    selectionButtonPressed();
  } 
} );

Later, you'll have to define selectionButtonPressed(). This works better when you have multiple buttons, because your calls to individual methods for handling the actions are right next to the definition of the button.

The second method also allows you to call the selection method directly. In this case, you could call selectionButtonPressed() if some other action happens, too - like, when a timer goes off or something (but in this case, your method would be named something different, maybe selectionChanged()).

Where ever you need to text in one line put this code

white-space:nowrap

Here is another tidyverse approach using the modify_at() function from the purrr package.

library(purrr)

# Data frame with only integer columns
data <- data.frame(matrix(sample(1:40), 4, 10, dimnames = list(1:4, LETTERS[1:10])))

# Modify specified columns to a factor class
data_with_factors <- data %>%
    purrr::modify_at(c("A", "C", "E"), factor)


# Check the results:
str(data_with_factors)
# 'data.frame':   4 obs. of  10 variables:
#  $ A: Factor w/ 4 levels "8","12","33",..: 1 3 4 2
#  $ B: int  25 32 2 19
#  $ C: Factor w/ 4 levels "5","15","35",..: 1 3 4 2
#  $ D: int  11 7 27 6
#  $ E: Factor w/ 4 levels "1","4","16","20": 2 3 1 4
#  $ F: int  21 23 39 18
#  $ G: int  31 14 38 26
#  $ H: int  17 24 34 10
#  $ I: int  13 28 30 29
#  $ J: int  3 22 37 9

More precisely, add the code below to the private void InitializeComponent() method of the Form class:

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;

ASCII has 128 code points, 0 through 127. It can fit in a single 8-bit byte, the values 128 through 255 tended to be used for other characters. With incompatible choices, causing the code page disaster. Text encoded in one code page cannot be read correctly by a program that assumes or guessed at another code page.

Unicode came about to solve this disaster. Version 1 started out with 65536 code points, commonly encoded in 16 bits. Later extended in version 2 to 1.1 million code points. The current version is 6.3, using 110,187 of the available 1.1 million code points. That doesn't fit in 16 bits anymore.

Encoding in 16-bits was common when v2 came around, used by Microsoft and Apple operating systems for example. And language runtimes like Java. The v2 spec came up with a way to map those 1.1 million code points into 16-bits. An encoding called UTF-16, a variable length encoding where one code point can take either 2 or 4 bytes. The original v1 code points take 2 bytes, added ones take 4.

Another variable length encoding that's very common, used in *nix operating systems and tools is UTF-8, a code point can take between 1 and 4 bytes, the original ASCII codes take 1 byte the rest take more. The only non-variable length encoding is UTF-32, takes 4 bytes for a code point. Not often used since it is pretty wasteful. There are other ones, like UTF-1 and UTF-7, widely ignored.

An issue with the UTF-16/32 encodings is that the order of the bytes will depend on the endian-ness of the machine that created the text stream. So add to the mix UTF-16BE, UTF-16LE, UTF-32BE and UTF-32LE.

Having these different encoding choices brings back the code page disaster to some degree, along with heated debates among programmers which UTF choice is "best". Their association with operating system defaults pretty much draws the lines. One counter-measure is the definition of a BOM, the Byte Order Mark, a special codepoint (U+FEFF, zero width space) at the beginning of a text stream that indicates how the rest of the stream is encoded. It indicates both the UTF encoding and the endianess and is neutral to a text rendering engine. Unfortunately it is optional and many programmers claim their right to omit it so accidents are still pretty common.

Usually, activating a virtualenv gives you a shell function named:

$ deactivate

which puts things back to normal.

I have just looked specifically again at the code for virtualenvwrapper, and, yes, it too supports deactivate as the way to escape from all virtualenvs.

If you are trying to leave an Anaconda environment, the command depends upon your version of conda. Recent versions (like 4.6) install a conda function directly in your shell, in which case you run:

conda deactivate

Older conda versions instead implement deactivation using a stand-alone script:

source deactivate

First you need an object

public class MyObject {
  public string Id {get;set;}
  public string Text {get;set;}
  ...
}

Then in here

    using (var twitpicResponse = (HttpWebResponse)request.GetResponse()) {

        using (var reader = new StreamReader(twitpicResponse.GetResponseStream())) {
            JavaScriptSerializer js = new JavaScriptSerializer();
            var objText = reader.ReadToEnd();
            MyObject myojb = (MyObject)js.Deserialize(objText,typeof(MyObject));
        }

    }

I haven't tested with the hierarchical object you have, but this should give you access to the properties you want.

JavaScriptSerializer System.Web.Script.Serialization

Because python checks in the directories in sequential order starting at the first directory in sys.path list, till it find the .py file it was looking for.

Ideally, the current directory or the directory of the script is the first always the first element in the list, unless you modify it, like you did. From documentation -

As initialized upon program startup, the first item of this list, path[0], is the directory containing the script that was used to invoke the Python interpreter. If the script directory is not available (e.g. if the interpreter is invoked interactively or if the script is read from standard input), path[0] is the empty string, which directs Python to search modules in the current directory first. Notice that the script directory is inserted before the entries inserted as a result of PYTHONPATH.

So, most probably, you had a .py file with the same name as the module you were trying to import from, in the current directory (where the script was being run from).

Also, a thing to note about ImportErrors , lets say the import error says - ImportError: No module named main - it doesn't mean the main.py is overwritten, no if that was overwritten we would not be having issues trying to read it. Its some module above this that got overwritten with a .py or some other file.

Example -

My directory structure looks like -

 - test
    - shared
         - __init__.py
         - phtest.py
  - testmain.py

Now From testmain.py , I call from shared import phtest , it works fine.

Now lets say I introduce a shared.py in test directory` , example -

 - test
    - shared
         - __init__.py
         - phtest.py
  - testmain.py 
  - shared.py

Now when I try to do from shared import phtest from testmain.py , I will get the error -

ImportError: cannot import name 'phtest'

As you can see above, the file that is causing the issue is shared.py , not phtest.py .

Here is the conversion from aioobe converted to Kotlin:

/**
 * https://stackoverflow.com/a/3758880/1006741
 */
fun Long.humanReadableByteCountBinary(): String {
    val b = when (this) {
        Long.MIN_VALUE -> Long.MAX_VALUE
        else -> abs(this)
    }
    return when {
        b < 1024L -> "$this B"
        b <= 0xfffccccccccccccL shr 40 -> "%.1f KiB".format(Locale.UK, this / 1024.0)
        b <= 0xfffccccccccccccL shr 30 -> "%.1f MiB".format(Locale.UK, this / 1048576.0)
        b <= 0xfffccccccccccccL shr 20 -> "%.1f GiB".format(Locale.UK, this / 1.073741824E9)
        b <= 0xfffccccccccccccL shr 10 -> "%.1f TiB".format(Locale.UK, this / 1.099511627776E12)
        b <= 0xfffccccccccccccL -> "%.1f PiB".format(Locale.UK, (this shr 10) / 1.099511627776E12)
        else -> "%.1f EiB".format(Locale.UK, (this shr 20) / 1.099511627776E12)
    }
}

This is a straight forward solution of 3 steps in Swift.

import MessageUI

Add to conform the Delegate

MFMailComposeViewControllerDelegate

And just create your method:

    func sendEmail() {
    if MFMailComposeViewController.canSendMail() {
        let mail = MFMailComposeViewController()
        mail.mailComposeDelegate = self
        mail.setToRecipients(["[email protected]"])
        mail.setSubject("Support App")
        mail.setMessageBody("<p>Send us your issue!</p>", isHTML: true)
        presentViewController(mail, animated: true, completion: nil)
    } else {
        // show failure alert
    }
}

func mailComposeController(controller: MFMailComposeViewController, didFinishWithResult result: MFMailComposeResult, error: NSError?) {

Your class's constructor method should be called __construct(), not __constructor():

public function __construct(EntityManager $entityManager)
{
    $this->em = $entityManager;
}

In case you are looking to include the font awesome library without having to do module imports and npm installs, put this in the head section of your React index.html page:

public/index.html (in head section)

<link rel="stylesheet" href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/4.7.0/css/font-awesome.min.css"/>

Then in your component (such as App.js) just use standard font awesome class convention. Just remember to use className instead of class:

<button className='btn'><i className='fa fa-home'></i></button>

If your application only works in portrait orientation, this is enough:

[[[UIApplication sharedApplication] keyWindow] addSubview:yourView]

And your view will not be shown over keyboard and status bar.

If you want to get a topmost view that over keyboard or status bar, or you want the topmost view can rotate correctly with devices, please try this framework:

https://github.com/HarrisonXi/TopmostView

It supports iOS7/8/9.

there is a case statement, but i think the below is more accurate/efficient/easier to read for what you want.

select 
  product
  ,coalesce(t4.price,t2.price, t3.price) as price
from table1 t1
left join table1 t2 on t1.product = t2.product and t2.customer =2
left join table1 t3 on t1.product = t3.product and t3.company =3
left join table1 t4 on t1.product = t4.product and t4.project =1

It may be easier to use XPath to locate the nodes that you wish to delete. This stackoverflow thread might give you some ideas.

In your case you will find the four nodes that you want using this expression:

XmlDocument doc = new XmlDocument();
doc.Load(fileName);
XmlNodeList nodes = doc.SelectNodes("//Setting[@name='File1']");

If i understood your question correctly you can add multiple columns in a table by using below mentioned query.

Query:

Alter table tablename add (column1 dataype, column2 datatype);

It is because by default at the time of this writing , Ionic CLI tool is defaulted to

<preference name="android-targetSdkVersion" value="LATEST_SDK_VERSION"/> 

That is the reason why it complains that you did not accept license agreement , but in reality you did not install the SDK packages for that API Level yet alone accept the license.

So what you need to do is either

1. Change Your target SDK version
2. Install latest SDK API level from SDK Manager

Changing your SDK version

You can do it manually and even verify it by running

ionic cordova platform add android 

the file can be found at your-awesome-app/config.xml open it and add this line , since its hidden as stated above

<preference name="android-targetSdkVersion" value="24"/>

If you are not sure which API LEVEL Number you are targeting open SDK Manager and look at the API levels (Numbers) available on your machine

Installing Latest SDK Package

You can add the current SDK Packages which the CLI is showing , Which in your case it is 24

Run SDK MANAGER as Admin

Install the SDK API Packages which you are targeting

How did I know this? I did it this morning and that's how I solved it and now am playing Sticky Bubble on Android to relax a bit.

Happy Deploying!

Nonetheless, you can use below code as,

$a = array('name1','name2','name3');
$b = array('email1','email2','email3');

function f($a,$b){
    return "The name is $a and email is $b, thank you";
}

$c = array_map('f', $a, $b);

//echoing the result

foreach ($c as $val) {
    echo $val.'<br>';
}

Remove the alpha channel using this command in the folder 'Images.xcassets', this command will remove all alpha channels from your .png files and it will put the background color to white

for i in `ls *.png`; do convert $i -background white -alpha remove -alpha off $i; done

To create a comma separated list from an IList<string> or IEnumerable<string>, besides using string.Join() you can use the StringBuilder.AppendJoin method:

new StringBuilder().AppendJoin(", ", itemList).ToString();

or

$"{new StringBuilder().AppendJoin(", ", itemList)}";

A combination of line styles, markers, and qualitative colors from matplotlib:

import itertools
import matplotlib as mpl
import matplotlib.pyplot as plt
N = 8*4+10
l_styles = ['-','--','-.',':']
m_styles = ['','.','o','^','*']
colormap = mpl.cm.Dark2.colors   # Qualitative colormap
for i,(marker,linestyle,color) in zip(range(N),itertools.product(m_styles,l_styles, colormap)):
    plt.plot([0,1,2],[0,2*i,2*i], color=color, linestyle=linestyle,marker=marker,label=i)
plt.legend(bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.,ncol=4);

UPDATE: Supporting not only ListedColormap, but also LinearSegmentedColormap

import itertools
import matplotlib.pyplot as plt
Ncolors = 8
#colormap = plt.cm.Dark2# ListedColormap
colormap = plt.cm.viridis# LinearSegmentedColormap
Ncolors = min(colormap.N,Ncolors)
mapcolors = [colormap(int(x*colormap.N/Ncolors)) for x in range(Ncolors)]
N = Ncolors*4+10
l_styles = ['-','--','-.',':']
m_styles = ['','.','o','^','*']
fig,ax = plt.subplots(gridspec_kw=dict(right=0.6))
for i,(marker,linestyle,color) in zip(range(N),itertools.product(m_styles,l_styles, mapcolors)):
    ax.plot([0,1,2],[0,2*i,2*i], color=color, linestyle=linestyle,marker=marker,label=i)
ax.legend(bbox_to_anchor=(1.05, 1), loc=2, borderaxespad=0.,ncol=3,prop={'size': 8})

To reference an element by id, you need to use the # qualifier.

Try:

alert($("#link1").text());

To replace it, you could use:

$("#link1").text('New text');

The .html() function would work in this case too.

This worked for me, no need to keep a lastSelected if you know the optionIndex to select.

var optionIndex = ...
$(this)[0].options[optionIndex].selected = true;

Yes, you can do that like this:

BEGIN
   DECLARE @Results TABLE (Tid INT PRIMARY KEY);

   INSERT @Results

   EXEC Procedure2 [parameters];
   SET @total 1;

END
SELECT @total

You can also go to Notepad++ and do the following steps:

Edit->LineOperations-> Remove Empty Lines or Remove Empty Lines(Containing blank characters)

host -a works well, similar to dig any.

if i understood you can do the following

Right Click on View Name in SQL Server Management Studio -> Script View As ->CREATE To ->New Query Window

In a SQL Server trigger you have available two psdeuotables called inserted and deleted. These contain the old and new values of the record.

So within the trigger (you can look up the create trigger parts easily) you would do something like this:

Insert table2 (user_id, user_name)
select user_id, user_name from inserted i
left join table2 t on i.user_id = t.userid
where t.user_id is null

When writing triggers remember they act once on the whole batch of information, they do not process row-by-row. So account for multiple row inserts in your code.

Swift 3.0

let request = NSMutableURLRequest(url: NSURL(string: "http://httpstat.us/200")! as URL)
let session = URLSession.shared
request.httpMethod = "GET"
request.addValue("application/json", forHTTPHeaderField: "Content-Type")
request.addValue("application/json", forHTTPHeaderField: "Accept")

let task = session.dataTask(with: request as URLRequest, completionHandler: {data, response, error -> Void in
      if error != nil {
          print("Error: \(String(describing: error))")
      } else {
          print("Response: \(String(describing: response))")
      }
 })

 task.resume()

Returning the new object fits with the REST principle of "Uniform Interface - Manipulation of resources through representations." The complete object is the representation of the new state of the object that was created.

There is a really excellent reference for API design, here: Best Practices for Designing a Pragmatic RESTful API

It includes an answer to your question here: Updates & creation should return a resource representation

It says:

To prevent an API consumer from having to hit the API again for an updated representation, have the API return the updated (or created) representation as part of the response.

Seems nicely pragmatic to me and it fits in with that REST principle I mentioned above.

public async Task<model> GetSomething(int id)
{
    return await context.model.FindAsync(id);
}

Maybe this will help

Take out bottom button from the nestedscrollview and take linearlayout as parent. Add bottom and nestedscrollview as thier children. It will work absolutely fine. In manifest for the activity use this - this will raise the button when the keyboard is opened

A bit of powershell magic will do the trick:

cmdkey /add:"SERVER:1433" /user:"DOMAIN\USERNAME" /pass:"PASSWORD"

Then just select windows authentication

Based on Jakub's answer you can configure the following git aliases for convenience:

accept-ours = "!f() { git checkout --ours -- \"${@:-.}\"; git add -u \"${@:-.}\"; }; f"
accept-theirs = "!f() { git checkout --theirs -- \"${@:-.}\"; git add -u \"${@:-.}\"; }; f"

They optionally take one or several paths of files to resolve and default to resolving everything under the current directory if none are given.

Add them to the [alias] section of your ~/.gitconfig or run

git config --global alias.accept-ours '!f() { git checkout --ours -- "${@:-.}"; git add -u "${@:-.}"; }; f'
git config --global alias.accept-theirs '!f() { git checkout --theirs -- "${@:-.}"; git add -u "${@:-.}"; }; f'

Suppose STUDENTID contains some characters or numbers that you already know i.e. 'searchstring' then below query will work for you.

You could try this:

select * from STUDENTS where CHARINDEX('searchstring',STUDENTID)>0

I think this one is the fastest and easiest one.

This warning comes because your dataframe x is a copy of a slice. This is not easy to know why, but it has something to do with how you have come to the current state of it.

You can either create a proper dataframe out of x by doing

x = x.copy()

This will remove the warning, but it is not the proper way

You should be using the DataFrame.loc method, as the warning suggests, like this:

x.loc[:,'Mass32s'] = pandas.rolling_mean(x.Mass32, 5).shift(-2)

In Swift:

For example, name of your custom class is InfoView

At first, you create files InfoView.xib and InfoView.swiftlike this:

import Foundation
import UIKit

class InfoView: UIView {
    class func instanceFromNib() -> UIView {
    return UINib(nibName: "InfoView", bundle: nil).instantiateWithOwner(nil, options: nil)[0] as! UIView
}

Then set File's Owner to UIViewController like this:

Rename your View to InfoView:

Right-click to File's Owner and connect your view field with your InfoView:

Make sure that class name is InfoView:

And after this you can add the action to button in your custom class without any problem:

And usage of this custom class in your MainViewController:

func someMethod() {
    var v = InfoView.instanceFromNib()
    v.frame = self.view.bounds
    self.view.addSubview(v)
}

Since TestRef is a class (which are reference objects), you can change the contents inside t without passing it as a ref. However, if you pass t as a ref, TestRef can change what the original t refers to. i.e. make it point to a different object.

It seems that everybody keeps referring to a single REPLACE function. Or even many calls of a REPLACE function. But when you have dynamic output with an unknown number of spaces, it wont work. Anybody that deals with this issue on a regular basis knows that REPLACE will only remove a single space, NOT ALL, as it should. And LTRIM and RTRIM seem to have the same issue. Leave it to Microsoft. Here's a sample output that uses a WHILE Loop to remove ALL CHAR(32) values (space).

DECLARE @INPUT_VAL  VARCHAR(8000)
DECLARE @OUTPUT_VAL VARCHAR(8000)

SET @INPUT_VAL = '      C               A                         '
SET @OUTPUT_VAL = @INPUT_VAL
WHILE CHARINDEX(CHAR(32), @OUTPUT_VAL) > 0 BEGIN
    SET @OUTPUT_VAL = REPLACE(@INPUT_VAL, CHAR(32), '')
END

PRINT 'START:' + @INPUT_VAL + ':END'
PRINT 'START:' + @OUTPUT_VAL + ':END'

Here's the output of the above code:

START:      C               A                         :END
START:CA:END

Now to take it a step further and utilize it in an UPDATE or SELECT statement, change it to a udf.

CREATE FUNCTION udf_RemoveSpaces (@INPUT_VAL    VARCHAR(8000))
RETURNS VARCHAR(8000)
AS 
BEGIN

DECLARE @OUTPUT_VAL VARCHAR(8000)
SET @OUTPUT_VAL = @INPUT_VAL
-- ITTERATE THROUGH STRING TO LOOK FOR THE ASCII VALUE OF SPACE (CHAR(32)) REPLACE IT WITH BLANK, NOT NULL
WHILE CHARINDEX(CHAR(32), @OUTPUT_VAL) > 0 BEGIN
    SET @OUTPUT_VAL = REPLACE(@INPUT_VAL, CHAR(32), '')
END

RETURN @OUTPUT_VAL
END

Then utilize the function in a SELECT or INSERT statement:

UPDATE A
SET STATUS_REASON_CODE = WHATEVER.dbo.udf_RemoveSpaces(STATUS_REASON_CODE)
FROM WHATEVER..ACCT_INFO A
WHERE A.SOMEVALUE = @SOMEVALUE

INSERT INTO SOMETABLE
(STATUS_REASON_CODE)
SELECT WHATEVER.dbo.udf_RemoveSpaces(STATUS_REASON_CODE)
FROM WHATEVER..ACCT_INFO A
WHERE A.SOMEVALUE = @SOMEVALUE

Oracle (database) can use many ports. when you install the software it scans for free ports and decides which port to use then.

The database listener defaults to 1520 but will use 1521 or 1522 if 1520 is not available. This can be adjusted in the listener.ora files.

The Enterprise Manager, web-based database administration tool defaults to port 80 but will use 8080 if 80 is not available.

See here for details on how to change the port number for enterprise manager: http://download-uk.oracle.com/docs/cd/B14099_19/integrate.1012/b19370/manage_oem.htm#i1012853

To elevate what jocull mentioned in a comment, I was doing everything mention in this thread and striking out... because mine was in a loop to be run over and over; after the first time through the loop, it would sometimes fail. Always worked the first time through the loop.

To be clear: the loop includes the creation of SmtpClient, and then doing .Send with the right data. The SmtpClient was created inside a try/catch block, to catch errors and to be sure the object got destroyed before the bottom of the loop.

In my case, the solution was to make sure that SmtpClient was disposed after each time in the loop (either via using() statement or by doing a manual dispose). Even if the SmtpClient object is being implicitly destroyed in the loop, .NET appears to be leaving stuff lying around to conflict with the next attempt.

public static void main(String arg[])
{
    HashMap<String, ArrayList<String>> hashmap = 
        new HashMap<String, ArrayList<String>>();
    ArrayList<String> arraylist = new ArrayList<String>();
    arraylist.add("Hello");
    arraylist.add("World.");
    hashmap.put("my key", arraylist);
    arraylist = hashmap.get("not inserted");
    System.out.println(arraylist);
    arraylist = hashmap.get("my key");
    System.out.println(arraylist);
}

null
[Hello, World.]

Works fine... maybe you find your mistake in my code.

Join on one-to-many relation in JPQL looks as follows:

select b.fname, b.lname from Users b JOIN b.groups c where c.groupName = :groupName 

When several properties are specified in select clause, result is returned as Object[]:

Object[] temp = (Object[]) em.createNamedQuery("...")
    .setParameter("groupName", groupName)
    .getSingleResult(); 
String fname = (String) temp[0];
String lname = (String) temp[1];

By the way, why your entities are named in plural form, it's confusing. If you want to have table names in plural, you may use @Table to specify the table name for the entity explicitly, so it doesn't interfere with reserved words:

@Entity @Table(name = "Users")     
public class User implements Serializable { ... } 

<b> and <i> should be avoided because they describe the style of the text. Instead, use <strong> and <em> because that describes the semantics (the meaning) of the text.

As with all things in HTML, you should be thinking not about how you want it to look, but what you actually mean. Sure, it might just be bold and italics to you, but not to a screen reader.

View if you need change background color , Space if not .

that dosent mean you have to change view background .

<View
    android:layout_width="match_parent"
    android:layout_height="20dp"
    android:background="@color/YOUR_BACKGROUND">
</View>

or Space

<Space
        android:layout_width="match_parent"
        android:layout_height="20dp"
         />

You can float the elements (the map wrapper, and the paragraph), or use inline-block on both of them.

I tried this in my Angular project and it worked fine without jQuery.

<input type='text' ng-paste='preventPaste($event)'>

And in script part:

$scope.preventPaste = function(e){
   e.preventDefault();
   return false;
};

In non angular project, use 'onPaste' instead of 'ng-paste' and 'event' instesd of '$event'.

Since Service is a Context, the variable context must be this:

DataBaseManager dbm = Utils.getDataManager(this);   

It always best to start any custom PHP project with a bootstrap file where you define the most commonly used paths as constants, based on values extracted from $_SERVER. It should make migrating your projects or parts of your project to another server or to another directory on the server a hell of a lot easier.

This is how I define my root paths :

define("LOCAL_PATH_ROOT", $_SERVER["DOCUMENT_ROOT"]);
define("HTTP_PATH_ROOT", isset($_SERVER["HTTP_HOST"]) ? $_SERVER["HTTP_HOST"] : (isset($_SERVER["SERVER_NAME"]) ? $_SERVER["SERVER_NAME"] : '_UNKNOWN_'));

The path LOCAL_PATH_ROOT is the document root. The path HTTP_PATH_ROOT is the equivalent when accessing the same path via HTTP.

At that point, converting any local path to an HTTP path can be done with the following code :

str_replace(LOCAL_PATH_ROOT, RELATIVE_PATH_ROOT, $my_path)

If you want to ensure compatibility with Windows based servers, you'll need to replace the directory seperator with a URL seperator as well :

str_replace(LOCAL_PATH_ROOT, RELATIVE_PATH_ROOT, str_replace(DIRECTORY_SEPARATOR, '/', $my_path))

Here's the full bootstrap code that I'm using for the PHP PowerTools boilerplate :

If you add the above code to your own project, outputting all user constants at this point (which you can do with get_defined_constants(true) should give a result that looks somewhat like this :

You are doing everything right by using a to_date function and specifying the time. The time is there in the database. The trouble is just that when you select a column of DATE datatype from the database, the default format mask doesn't show the time. If you issue a

alter session set nls_date_format = 'dd/MON/yyyy hh24:mi:ss'

or something similar including a time component, you will see that the time successfully made it into the database.

Include sites-available/default in sites-enabled/default. It requires only one line.

In sites-enabled/default (new config version?):

It seems that the include path is relative to the file that included it

include sites-available/default;

See the include documentation.

I believe that certain versions of nginx allows including/linking to other files purely by having a single line with the relative path to the included file. (At least that's what it looked like in some "inherited" config files I've been using, until a new nginx version broke them.)

In sites-enabled/default (old config version?):

It seems that the include path is relative to the current file

../sites-available/default

ctypes can be used to access dlls, here's a tutorial:

http://docs.python.org/library/ctypes.html#module-ctypes

Try something like:

SELECT       `column`
    FROM     `your_table`
    GROUP BY `column`
    ORDER BY COUNT(*) DESC
    LIMIT    1;

I created a extension method that is much simpiler than the answers that are posted. and the aspect ratio is applied without cropping the image.

public static Image Resize(this Image image, int width, int height) {
     var scale = Math.Min(height / (float)image.Height, width / (float)image.Width);
     return image.GetThumbnailImage((int)(image.Width * scale), (int)(image.Height * scale), () => false, IntPtr.Zero);
}

Example usage:

using (var img = Image.FromFile(pathToOriginalImage)) {
    using (var thumbnail = img.Resize(60, 60)){
        // Here you can do whatever you need to do with thumnail
    }
}

This one is wrong at least:

            for x in range(x, 1, 1):
        elif option == 0:

Send a SIGTERM or a SIGKILL to it:

http://en.wikipedia.org/wiki/SIGKILL

http://en.wikipedia.org/wiki/SIGTERM

SIGTERM is polite and lets the process clean up before it goes, whereas, SIGKILL is for when it won't listen >:)

Example from the shell (man page: http://unixhelp.ed.ac.uk/CGI/man-cgi?kill )

kill -9 pid

In C, you can do the same thing using the kill syscall:

kill(pid, SIGKILL);
