Issue solved by setting this env variable:

export HOMEBREW_FORCE_BREWED_CURL=1

What I usually do is:

if (cond1 == 'val1' and cond2 == 'val2' and
    cond3 == 'val3' and cond4 == 'val4'
   ):
    do_something

this way the closing brace and colon visually mark the end of our condition.

Attribute_Brands is a named range that should contain your list items. Use the drop down to the left of the formula bar to jump to the named range, then edit it. If you add or remove items you will need to adjust the range the named range covers.

You might also want to define the imeOptions within the EditText. This way, the keyboard will go away once you press on Done:

<EditText
    android:id="@+id/editText1"
    android:inputType="text"
    android:imeOptions="actionDone"/>

It is possible to get this working in VS Code and have the Cmder terminal be integrated (not pop up).

To do so:

1. Create an environment variable "CMDER_ROOT" pointing to your Cmder directory.
2. In (Preferences > User Settings) in VS Code add the following settings:

"terminal.integrated.shell.windows": "cmd.exe"

"terminal.integrated.shellArgs.windows": ["/k", "%CMDER_ROOT%\\vendor\\init.bat"]

Here's a one liner (yes, it is similar to user333700's, but a little more straightforward):

>>> import numpy as np
>>> arr = np.array([[ 0.96488889, 0.73641667, 0.67521429, 0.592875, 0.53172222], 
                [ 0.78008333, 0.5938125, 0.481, 0.39883333, 0.]])
>>> print arr[arr.all(1)]
array([[ 0.96488889,  0.73641667,  0.67521429,  0.592875  ,  0.53172222]])

By the way, this method is much, much faster than the masked array method for large matrices. For a 2048 x 5 matrix, this method is about 1000x faster.

By the way, user333700's method (from his comment) was slightly faster in my tests, though it boggles my mind why.

Hey guys this is a good way of link w/ image and has lot of props in case you want to css attribute for example replace "alt" or "title" etc.....also including a logical restriction (?)

<%= link_to image_tag("#{request.ssl? ? @image_domain_secure : @image_domain}/images/linkImage.png", {:alt=>"Alt title", :title=>"Link title"}) , "http://www.site.com"%>

Hope this helps!

I tried WebLoad it's a pretty neat tool. It comes with and test script IDE which allows you to record user action on a website. It also draws a graph as it perform stress test on your web server. Try it out, I highly recommend it.

for Axis2 client this may be helpful

...
serviceStub = new TestBeanServiceStub("<WEB SERVICE URL>"); // Set your value
HttpTransportProperties.Authenticator basicAuthenticator = new HttpTransportProperties.Authenticator();
List<String> authSchemes = new ArrayList<String>();
authSchemes.add(Authenticator.BASIC);
basicAuthenticator.setAuthSchemes(authSchemes); 
basicAuthenticator.setUsername("<UserName>"); // Set your value
basicAuthenticator.setPassword("<Password>"); // Set your value
basicAuthenticator.setPreemptiveAuthentication(true);
serviceStub._getServiceClient().getOptions().setProperty(org.apache.axis2.transport.http.HTTPConstants.AUTHENTICATE, basicAuthenticator);
serviceStub._getServiceClient().getOptions().setProperty(org.apache.axis2.transport.http.HTTPConstants.CHUNKED, "false");
...

selector is used for applying multiple alternate drawables for different status of the view, so in this case, there is no need for selector

instead use shape

<?xml version="1.0" encoding="utf-8"?>
    <shape xmlns:android="http://schemas.android.com/apk/res/android">
    <solid android:color="#ffffff" />
    <stroke android:width="1dip" android:color="#ff9900" />
</shape>

If you want to use environment params and other utils as well such as log, you can use gulp-util

/* 
  $npm install gulp-util --save-dev
  $gulp --varName 123
*/
var util = require('gulp-util');
util.log(util.env.varName);

Update

gulp-util is now deprecated. You can use minimist instead.

var argv = require('minimist')(process.argv.slice(2));
console.dir(argv);

Many string update functions in MySQL seems to be working like this: If one argument is null, then concatenation or other functions return null too. So, to update a field with null value, first set it to a non-null value, such as ''

For example:

update table set field='' where field is null;
update table set field=concat(field,' append');

This can happen in multiple cases:

1. When the complete string path is longer than 254 chars.
2. When the name of the file to be copied is wrong.
3. When the target path is wrong.
4. When the readonly attribute is set on the copied file or target folder.

One more scenario of this error:

Install typescript locally and run the command without npm run

First, it is important to notice this is a "general" terminal error (Even if you write hello bla.js -or- wowowowow index.js):

"hello world" example of this error:

1. You install typescript locally (without -g) ==> npm install typescript. https://docs.npmjs.com/downloading-and-installing-packages-locally
2. In this case tsc commands available if you run npm run inside your local project. For example: npm run tsc -v:

-or- install typescript globally (Like other answer mention).

I found a solution on the MSDN forums. The sample code below will remove all Click events from button1.

public partial class Form1 : Form
{
    public Form1()
    {
        InitializeComponent();

        button1.Click += button1_Click;
        button1.Click += button1_Click2;
        button2.Click += button2_Click;
    }

    private void button1_Click(object sender, EventArgs e)  => MessageBox.Show("Hello");
    private void button1_Click2(object sender, EventArgs e) => MessageBox.Show("World");
    private void button2_Click(object sender, EventArgs e)  => RemoveClickEvent(button1);

    private void RemoveClickEvent(Button b)
    {
        FieldInfo f1 = typeof(Control).GetField("EventClick", 
            BindingFlags.Static | BindingFlags.NonPublic);

        object obj = f1.GetValue(b);
        PropertyInfo pi = b.GetType().GetProperty("Events",  
            BindingFlags.NonPublic | BindingFlags.Instance);

        EventHandlerList list = (EventHandlerList)pi.GetValue(b, null);
        list.RemoveHandler(obj, list[obj]);
    }
}

Try

List<SubProduct> subProducts = new List<SubProduct>(Model.subproduct);

or

List<SubProduct> subProducts = Model.subproducts as List<SubProduct>;

I found that if the application within the httpd server has a rule like "if the X-Frame-Options header exists and has a value, leave it alone; otherwise add the header X-Frame-Options: SAMEORIGIN" then an httpd.conf mod_headers rule like "Header always unset X-Frame-Options" would not suffice. The SAMEORIGIN value would always reach the client.

To remedy this, I add two, not one, mod_headers rules (in the outermost httpd.conf file):

Header set X-Frame-Options ALLOW-FROM http://to.be.deleted.com early
Header unset X-Frame-Options

The first rule tells any internal request handler that some other agent has taken responsibility for clickjack prevention and it can skip its attempt to save the world. It runs with "early" processing. The second rule strips off the entirely unwanted X-Frame-Options header. It runs with "late" processing.

I also add the appropriate Content-Security-Policy headers so that the world remains protected yet multi-sourced Javascript from trusted sites still gets to run.

You can use the -l option in the she-bang header:

#!/usr/bin/perl -l

$text = "hello";

print $text;
print $text;

Output:

hello
hello

String s1 = "Welcome"; // Does not create a new instance  
String s2 = new String("Welcome"); // Creates two objects and one reference variable  

For me above solutions didn't work when setting a specific color or property.

This did work:

let attributes = [
    NSFontAttributeName : UIFont(name: "Helvetica Neue", size: 12.0)!,
    NSUnderlineStyleAttributeName : 1,
    NSForegroundColorAttributeName : UIColor.darkGrayColor(),
    NSTextEffectAttributeName : NSTextEffectLetterpressStyle,
    NSStrokeWidthAttributeName : 3.0]

var atriString = NSAttributedString(string: "My Attributed String", attributes: attributes)

To get the current time in the local timezone as a naive datetime object:

from datetime import datetime
naive_dt = datetime.now()

If it doesn't return the expected time then it means that your computer is misconfigured. You should fix it first (it is unrelated to Python).

To get the current time in UTC as a naive datetime object:

naive_utc_dt = datetime.utcnow()

To get the current time as an aware datetime object in Python 3.3+:

from datetime import datetime, timezone

utc_dt = datetime.now(timezone.utc) # UTC time
dt = utc_dt.astimezone() # local time

To get the current time in the given time zone from the tz database:

import pytz

tz = pytz.timezone('Europe/Berlin')
berlin_now = datetime.now(tz)

It works during DST transitions. It works if the timezone had different UTC offset in the past i.e., it works even if the timezone corresponds to multiple tzinfo objects at different times.

Here are the steps to use ASP.NET MVC 5 in Visual Studio 2012:

• Start your ASP.NET MVC 4 project.
• Install-Package Microsoft.AspNet.WebApi -pre
• Install-Package Microsoft.AspNet.Mvc -Pre
• Install-Package Microsoft.AspNet.SignalR -Pre

These two will update:

• Microsoft.AspNet.Mvc 5.0.0-rc1
• Microsoft.AspNet.Razor
• Microsoft.AspNet.WebApi 5.0.0-rc1
• Microsoft.AspNet.WebApi.Client 5.0.0-rc1
• Microsoft.AspNet.WebApi.Core 5.0.0-rc1
• Microsoft.AspNet.WebApi.WebHost 5.0.0-rc1
• Microsoft.AspNet.WebPages 3.0.0-rc1
• and some other goodies

If these upgrades did not update your web.config, then check out this useful page: upgrading from MVC4 to MVC5.

It exits the function and returns nothing.

Something like return 1; would be incorrect since it returns integer 1.

The purrr package has a lot of handy functions for working on lists. The flatten command can clean up unwanted nesting.

resultsa <- list(1,2,3,4,5)
resultsb <- list(6,7,8,9,10)
resultsc <- list(11,12,13,14,15)

nested_outlist <- list(resultsa, resultsb, resultsc)
outlist <- purrr::flatten(nested_outlist)

2. Do CTRL-C.
3. Check if there is only lefting <!DOCTYPE html> before the <html>.

I came up with an easy way to do it, but I didn't create a new sub for it. Instead, I just "ran a check" within the sub I was working on. Assuming the sheet name we're looking for is "Sheet_Exist" and we just want to activate it if found:

Dim SheetCounter As Integer

SheetCounter = 1

Do Until Sheets(SheetCounter).Name = "Sheet_Exist" Or SheetCounter = Sheets.Count + 1
 SheetCounter = SheetCounter +1
Loop
If SheetCounter < Sheets.Count + 1 Then
 Sheets("Sheet_Exist").Activate
Else
 MsgBox("Worksheet ""Sheet_Exist"" was NOT found")
End If

I also added a pop-up for when the sheet doesn't exist.

Here's the raw reference of PDF 1.7, and here's an article describing the structure of a PDF file. If you use Vim, the pdftk plugin is a good way to explore the document in an ever-so-slightly less raw form, and the pdftk utility itself (and its GPL source) is a great way to tease documents apart.

I've found changing the JavaScript "key" variable like this:

//Fools the website into believing a human is navigating it
((JavascriptExecutor)driver).executeScript("window.key = \"blahblah\";");

works for some websites when using Selenium WebDriver along with Google Chrome, since many sites check for this variable in order to avoid being scraped by Selenium.

Zonble has already provided an excellent answer. I thought it may be useful to include a short code snippet for adding a UIView to the tableview cell that will present as the selected background view.

cell = [[[UITableViewCell alloc] initWithFrame:CGRectZero reuseIdentifier:CellIdentifier] autorelease];

    UIView *selectionColor = [[UIView alloc] init];
    selectionColor.backgroundColor = [UIColor colorWithRed:(245/255.0) green:(245/255.0) blue:(245/255.0) alpha:1];
    cell.selectedBackgroundView = selectionColor;

• cell is my UITableViewCell
• I created a UIView and set its background color using RGB colours (light gray)
• I then set the cell selectedBackgroundView to be the UIView that I created with my chosen background colour

This worked well for me. Thanks for the tip Zonble.

I was facing same problem below is the solution that worked for me

First Go to Android SDK Manager then

select Tools then,

select Options

then check the box "Force https://... sources to be fetched using http://..."

hope it will help you also.

You just need to add some line in your app, please find it from below link:

Show and hide a View with a slide up/down animation

Just add an animation to your layout like this:

mLayoutTab.animate()
  .translationYBy(120)
  .translationY(0)
  .setDuration(getResources().getInteger(android.R.integer.config_mediumAnimTime));

Neither of these options is correct. You're trying to implement a synchronous interface asynchronously. Don't do that. The problem is that when DoOperation() returns, the operation won't be complete yet. Worse, if an exception happens during the operation (which is very common with IO operations), the user won't have a chance to deal with that exception.

What you need to do is to modify the interface, so that it is asynchronous:

interface IIO
{
    Task DoOperationAsync(); // note: no async here
}

class IOImplementation : IIO
{
    public async Task DoOperationAsync()
    {
        // perform the operation here
    }
}

This way, the user will see that the operation is async and they will be able to await it. This also pretty much forces the users of your code to switch to async, but that's unavoidable.

Also, I assume using StartNew() in your implementation is just an example, you shouldn't need that to implement asynchronous IO. (And new Task() is even worse, that won't even work, because you don't Start() the Task.)

Something like this:

Dim rng As Range
Dim row As Range
Dim cell As Range

Set rng = Range("A1:C2")

For Each row In rng.Rows
  For Each cell in row.Cells
    'Do Something
  Next cell
Next row

Sorry because this is an old post and currently there is more options than before.

Rails 5 comes with an or method. (link to documentation)

This method accepts an ActiveRecord::Relation object. eg:

User.where(first_name: 'James').or(User.where(last_name: 'Scott'))

I am only posting this because I had a specific issue with the command line arguments I was passing in. Being inexperienced with the command line I was using "<" and ">" in my arguments and it was redirecting the file on me. Hope this helps someone.

Just create a data.frame with 0 length variables

eg

nodata <- data.frame(x= numeric(0), y= integer(0), z = character(0))
str(nodata)

## 'data.frame':    0 obs. of  3 variables:
##  $ x: num 
##  $ y: int 
##  $ z: Factor w/ 0 levels: 

or to create a data.frame with 5 columns named a,b,c,d,e

nodata <- as.data.frame(setNames(replicate(5,numeric(0), simplify = F), letters[1:5]))

div is a block element, which always takes up its own line.

use the span tag instead

Several answers have discussed the problems with the concept of overridable static methods. However sometimes you come across a pattern where it seems like that's just what you want to use.

For example, I work with an object-relational layer that has value objects, but also has commands for manipulating the value objects. For various reasons, each value object class has to define some static methods that let the framework find the command instance. For example, to create a Person you'd do:

cmd = createCmd(Person.getCreateCmdId());
Person p = cmd.execute();

and to load a Person by ID you'd do

cmd = createCmd(Person.getGetCmdId());
cmd.set(ID, id);
Person p = cmd.execute();

This is fairly convenient, however it has its problems; notably the existence of the static methods can not be enforced in the interface. An overridable static method in the interface would be exactly what we'd need, if only it could work somehow.

EJBs solve this problem by having a Home interface; each object knows how to find its Home and the Home contains the "static" methods. This way the "static" methods can be overridden as needed, and you don't clutter up the normal (it's called "Remote") interface with methods that don't apply to an instance of your bean. Just make the normal interface specify a "getHome()" method. Return an instance of the Home object (which could be a singleton, I suppose) and the caller can perform operations that affect all Person objects.

This works for me saving a numpy array plotted with imshow to file

import matplotlib.pyplot as plt

fig = plt.figure(figsize=(10,10))
plt.imshow(img) # your image here
plt.axis("off")
plt.subplots_adjust(top = 1, bottom = 0, right = 1, left = 0, 
        hspace = 0, wspace = 0)
plt.savefig("example2.png", box_inches='tight', dpi=100)
plt.show()

You can use a $where. Just be aware it will be fairly slow (has to execute Javascript code on every record) so combine with indexed queries if you can.

db.T.find( { $where: function() { return this.Grade1 > this.Grade2 } } );

or more compact:

db.T.find( { $where : "this.Grade1 > this.Grade2" } );

UPD for mongodb v.3.6+

you can use $expr as described in recent answer

I don't believe there's a way to query the mouse position, but you can use a mousemove handler that just stores the information away, so you can query the stored information.

jQuery(function($) {
    var currentMousePos = { x: -1, y: -1 };
    $(document).mousemove(function(event) {
        currentMousePos.x = event.pageX;
        currentMousePos.y = event.pageY;
    });

    // ELSEWHERE, your code that needs to know the mouse position without an event
    if (currentMousePos.x < 10) {
        // ....
    }
});

But almost all code, other than setTimeout code and such, runs in response to an event, and most events provide the mouse position. So your code that needs to know where the mouse is probably already has access to that information...

I have a naive solution but useful. Here is the code:

<Grid Name="TVGrid" Background="#7F000000">  <ScrollBar Background="Black" Orientation="Vertical" Height="35" HorizontalAlignment="Left" Margin="215,254,0,0" Minimum="0" Maximum="10" LargeChange="10" Value="{Binding ElementName=channeltext2, Path=Text}" x:Name="scroll" VerticalAlignment="Top" Width="12" RenderTransformOrigin="0.5,0.5" ValueChanged="scroll_ValueChanged" >  
        <ScrollBar.RenderTransform>  
            <TransformGroup>  
                <ScaleTransform/>  
                <SkewTransform/>  
                <RotateTransform Angle="-180"/>  
                <TranslateTransform/>  
            </TransformGroup>  
        </ScrollBar.RenderTransform>  
    </ScrollBar>  
    <TextBox Name="channeltext" HorizontalContentAlignment="Center" FontSize="20"  Background="Black" Foreground="White" Height="35" HorizontalAlignment="Left" Margin="147,254,0,0" VerticalAlignment="Top" Width="53" Text="0" />

I had luck with something similar:

Convert(DATETIME, CONVERT(VARCHAR(2), @Month) + '/' + CONVERT(VARCHAR(2), @Day)
+ '/' + CONVERT(VARCHAR(4), @Year))

So you cant have the behavior that you want but you can do something that feels like it. You want to be able to do Choice.first.question

what I have done in the past is something like this

class Choice
  belongs_to :user
  belongs_to :answer
  validates_uniqueness_of :answer_id, :scope => [ :question_id, :user_id ]
  ...
  def question
    answer.question
  end
end

this way the you can now call question on Choice

Addition to @hasen's answer. You might want to use git ls-files instead of find to list files to checkout like:

git ls-files -z *.txt | git checkout-index --prefix=/path-to/dest/ -f -z --stdin

git ls-files ignores uncommitted files.

You can use RTRIM or cast your value to VARCHAR:

SELECT RIGHT(RTRIM(Field),3), LEFT(Field,LEN(Field)-3)

Or

SELECT RIGHT(CAST(Field AS VARCHAR(15)),3), LEFT(Field,LEN(Field)-3)

But for one simple example (Printing in red) in Java (as you tagged this as Java) do:

System.out.println("\u001B31;1mhello world!");

The 3 indicates change color, the first 1 indicates red (green would be 2) and the second 1 indicates do it in "bright" mode.

GUI

However, if you want to print to a GUI the easiest way is to use html:

JEditorPane pane = new new JEditorPane();
pane.setText("<html><font color=\"red\">hello world!</font></html>");

For more details on this sort of thing, see the Swing Tutorial. It is also possible by using styles in a JTextPane. Here is a helpful example of code to do this easily with a JTextPane (added from helpful comment).

JTextArea is a single coloured Text component, as described here. It can only display in one color. You can set the color for the whole JTextArea like this:

JTextArea area = new JTextArea("hello world");
area.setForeground(Color.red)

"How can I directly (without saving the file on 2nd server) download the file from 1st server to client's machine?"

Just use the Client API and get the InputStream from the response

Client client = ClientBuilder.newClient();
String url = "...";
final InputStream responseStream = client.target(url).request().get(InputStream.class);

There are two flavors to get the InputStream. You can also use

Response response = client.target(url).request().get();
InputStream is = (InputStream)response.getEntity();

Which one is the more efficient? I'm not sure, but the returned InputStreams are different classes, so you may want to look into that if you care to.

From 2nd server I can get a ByteArrayOutputStream to get the file from 1st server, can I pass this stream further to the client using the REST service?

So most of the answers you'll see in the link provided by @GradyGCooper seem to favor the use of StreamingOutput. An example implementation might be something like

final InputStream responseStream = client.target(url).request().get(InputStream.class);
System.out.println(responseStream.getClass());
StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) throws IOException, WebApplicationException {  
        int length;
        byte[] buffer = new byte[1024];
        while((length = responseStream.read(buffer)) != -1) {
            out.write(buffer, 0, length);
        }
        out.flush();
        responseStream.close();
    }   
};
return Response.ok(output).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

But if we look at the source code for StreamingOutputProvider, you'll see in the writeTo, that it simply writes the data from one stream to another. So with our implementation above, we have to write twice.

How can we get only one write? Simple return the InputStream as the Response

final InputStream responseStream = client.target(url).request().get(InputStream.class);
return Response.ok(responseStream).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

If we look at the source code for InputStreamProvider, it simply delegates to ReadWriter.writeTo(in, out), which simply does what we did above in the StreamingOutput implementation

 public static void writeTo(InputStream in, OutputStream out) throws IOException {
    int read;
    final byte[] data = new byte[BUFFER_SIZE];
    while ((read = in.read(data)) != -1) {
        out.write(data, 0, read);
    }
}

Asides:

• Client objects are expensive resources. You may want to reuse the same Client for request. You can extract a WebTarget from the client for each request.

  WebTarget target = client.target(url);
  InputStream is = target.request().get(InputStream.class);
  

  I think the WebTarget can even be shared. I can't find anything in the Jersey 2.x documentation (only because it is a larger document, and I'm too lazy to scan through it right now :-), but in the Jersey 1.x documentation, it says the Client and WebResource (which is equivalent to WebTarget in 2.x) can be shared between threads. So I'm guessing Jersey 2.x would be the same. but you may want to confirm for yourself.

• You don't have to make use of the Client API. A download can be easily achieved with the java.net package APIs. But since you're already using Jersey, it doesn't hurt to use its APIs

• The above is assuming Jersey 2.x. For Jersey 1.x, a simple Google search should get you a bunch of hits for working with the API (or the documentation I linked to above)

UPDATE

I'm such a dufus. While the OP and I are contemplating ways to turn a ByteArrayOutputStream to an InputStream, I missed the simplest solution, which is simply to write a MessageBodyWriter for the ByteArrayOutputStream

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.lang.annotation.Annotation;
import java.lang.reflect.Type;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.MultivaluedMap;
import javax.ws.rs.ext.MessageBodyWriter;
import javax.ws.rs.ext.Provider;

@Provider
public class OutputStreamWriter implements MessageBodyWriter<ByteArrayOutputStream> {

    @Override
    public boolean isWriteable(Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return ByteArrayOutputStream.class == type;
    }

    @Override
    public long getSize(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return -1;
    }

    @Override
    public void writeTo(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType,
            MultivaluedMap<String, Object> httpHeaders, OutputStream entityStream)
            throws IOException, WebApplicationException {
        t.writeTo(entityStream);
    }
}

Then we can simply return the ByteArrayOutputStream in the response

return Response.ok(baos).build();

D'OH!

UPDATE 2

Here are the tests I used (

Resource class

@Path("test")
public class TestResource {

    final String path = "some_150_mb_file";

    @GET
    @Produces(MediaType.APPLICATION_OCTET_STREAM)
    public Response doTest() throws Exception {
        InputStream is = new FileInputStream(path);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        int len;
        byte[] buffer = new byte[4096];
        while ((len = is.read(buffer, 0, buffer.length)) != -1) {
            baos.write(buffer, 0, len);
        }
        System.out.println("Server size: " + baos.size());
        return Response.ok(baos).build();
    }
}

Client test

public class Main {
    public static void main(String[] args) throws Exception {
        Client client = ClientBuilder.newClient();
        String url = "http://localhost:8080/api/test";
        Response response = client.target(url).request().get();
        String location = "some_location";
        FileOutputStream out = new FileOutputStream(location);
        InputStream is = (InputStream)response.getEntity();
        int len = 0;
        byte[] buffer = new byte[4096];
        while((len = is.read(buffer)) != -1) {
            out.write(buffer, 0, len);
        }
        out.flush();
        out.close();
        is.close();
    }
}

UPDATE 3

So the final solution for this particular use case was for the OP to simply pass the OutputStream from the StreamingOutput's write method. Seems the third-party API, required a OutputStream as an argument.

StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) {
        thirdPartyApi.downloadFile(.., .., .., out);
    }
}
return Response.ok(output).build();

Not quite sure, but seems the reading/writing within the resource method, using ByteArrayOutputStream`, realized something into memory.

The point of the downloadFile method accepting an OutputStream is so that it can write the result directly to the OutputStream provided. For instance a FileOutputStream, if you wrote it to file, while the download is coming in, it would get directly streamed to the file.

It's not meant for us to keep a reference to the OutputStream, as you were trying to do with the baos, which is where the memory realization comes in.

So with the way that works, we are writing directly to the response stream provided for us. The method write doesn't actually get called until the writeTo method (in the MessageBodyWriter), where the OutputStream is passed to it.

You can get a better picture looking at the MessageBodyWriter I wrote. Basically in the writeTo method, replace the ByteArrayOutputStream with StreamingOutput, then inside the method, call streamingOutput.write(entityStream). You can see the link I provided in the earlier part of the answer, where I link to the StreamingOutputProvider. This is exactly what happens

Abstraction is Showing necessary info to the user where as Encapsulation hide the unwanted data from the user(Product from the user).

Encapsulation Implements the Abstraction.

Abstraction is the process where as Encapsulation actually implements it. For Eg. Adding user logic -> we need to validate the user , creating DB connection and insert the User. So user do not know fist need to call validate function , creating DB connection and then insert the Value in DB. He only call the AddUser function which call the internally all logic with in , this is only Encapsulation (Grouping the feature and hiding the methods).

My answer, perhaps listed already but i did not notice, was simple: I deleted the app in question from the target itself, then fired up Xcode and the target was then available. And yes, i tried most of the other suggestions, and was resorting to activating the target from the Product menu, but that was getting tedious.

exit is a helper for the interactive shell - sys.exit is intended for use in programs.

The site module (which is imported automatically during startup, except if the -S command-line option is given) adds several constants to the built-in namespace (e.g. exit). They are useful for the interactive interpreter shell and should not be used in programs.

Technically, they do mostly the same: raising SystemExit. sys.exit does so in sysmodule.c:

static PyObject *
sys_exit(PyObject *self, PyObject *args)
{
    PyObject *exit_code = 0;
    if (!PyArg_UnpackTuple(args, "exit", 0, 1, &exit_code))
        return NULL;
    /* Raise SystemExit so callers may catch it or clean up. */
    PyErr_SetObject(PyExc_SystemExit, exit_code);
   return NULL;
}

While exit is defined in site.py and _sitebuiltins.py, respectively.

class Quitter(object):
    def __init__(self, name):
        self.name = name
    def __repr__(self):
        return 'Use %s() or %s to exit' % (self.name, eof)
    def __call__(self, code=None):
        # Shells like IDLE catch the SystemExit, but listen when their
        # stdin wrapper is closed.
        try:
            sys.stdin.close()
        except:
            pass
        raise SystemExit(code)
__builtin__.quit = Quitter('quit')
__builtin__.exit = Quitter('exit')

Note that there is a third exit option, namely os._exit, which exits without calling cleanup handlers, flushing stdio buffers, etc. (and which should normally only be used in the child process after a fork()).

According to the help of cmake:

-C <initial-cache>
     Pre-load a script to populate the cache.

     When cmake is first run in an empty build tree, it creates a CMakeCache.txt file and populates it with customizable settings for the project.  This option may be used to specify a  file  from
     which to load cache entries before the first pass through the project's cmake listfiles.  The loaded entries take priority over the project's default values.  The given file should be a CMake
     script containing SET commands that use the CACHE option, not a cache-format file.

You make be able to create files like gcc_compiler.txt and clang_compiler.txt to includes all relative configuration in CMake syntax.

Clang Example (clang_compiler.txt):

 set(CMAKE_C_COMPILER "/usr/bin/clang" CACHE string "clang compiler" FORCE)

Then run it as

GCC:

cmake -C gcc_compiler.txt XXXXXXXX

Clang:

cmake -C clang_compiler.txt XXXXXXXX

Following solution will drop specific default constraint of a column from the table

Declare @Const NVARCHAR(256)

SET @Const = (
              SELECT TOP 1 'ALTER TABLE' + YOUR TABLE NAME +' DROP CONSTRAINT '+name
              FROM Sys.default_constraints A
              JOIN sysconstraints B on A.parent_object_id = B.id
              WHERE id = OBJECT_ID('YOUR TABLE NAME')
              AND COL_NAME(id, colid)='COLUMN NAME'
              AND OBJECTPROPERTY(constid,'IsDefaultCnst')=1
            )
 EXEC (@Const)

setState(updater[, callback]) is an async function:

https://facebook.github.io/react/docs/react-component.html#setstate

You can execute a function after setState is finishing using the second param callback like:

this.setState({
    someState: obj
}, () => {
    this.afterSetStateFinished();
});

The same can be done with hooks in React functional component:

https://github.com/the-road-to-learn-react/use-state-with-callback#usage

Look at useStateWithCallbackLazy:

import { useStateWithCallbackLazy } from 'use-state-with-callback';

const [count, setCount] = useStateWithCallbackLazy(0);

setCount(count + 1, () => {
   afterSetCountFinished();
});

Took a lot of googling but here is what I do in Python for MySql when I want to delete multiple items from a single table using a list of values.

#create some empty list
values = []
#continue to append the values you want to delete to it
#BUT you must ensure instead of a string it's a single value tuple
values.append(([Your Variable],))
#Then once your array is loaded perform an execute many
cursor.executemany("DELETE FROM YourTable WHERE ID = %s", values)

The requests.Session() solution assisted with logging into a form with CSRF Protection (as used in Flask-WTF forms). Check if a csrf_token is required as a hidden field and add it to the payload with the username and password:

import requests
from bs4 import BeautifulSoup

payload = {
    'email': '[email protected]',
    'password': 'passw0rd'
}     

with requests.Session() as sess:
    res = sess.get(server_name + '/signin')
    signin = BeautifulSoup(res._content, 'html.parser')
    payload['csrf_token'] = signin.find('input', id='csrf_token')['value']
    res = sess.post(server_name + '/auth/login', data=payload)

This will get you close, the add button has been removed out of the table so you might want to consider this...

<script type="text/javascript">
    $(document).ready(function() {
        $("#add").click(function() {
          $('#mytable tbody>tr:last').clone(true).insertAfter('#mytable tbody>tr:last');
          return false;
        });
    });
</script>

HTML markup looks like this

  <a  id="add">+</a></td>
  <table id="mytable" width="300" border="1" cellspacing="0" cellpadding="2">
  <tbody>
    <tr>
      <td>Name</td>
    </tr>
    <tr class="person">
      <td><input type="text" name="name" id="name" /></td>
    </tr>
    </tbody>
  </table>

EDIT To empty a value of a textbox after insert..

    $('#mytable tbody>tr:last').clone(true).insertAfter('#mytable tbody>tr:last');
    $('#mytable tbody>tr:last #name').val('');
    return false;

EDIT2 Couldn't help myself, to reset all dropdown lists in the inserted TR you can do this

$("#mytable tbody>tr:last").each(function() {this.reset();});           

I will leave the rest to you!

Below is the example to remove the element from the list.

 List<int> items = new List<int>() { 2, 2, 3, 4, 2, 7, 3,3,3};

 var result = items.Remove(2);//Remove the first ocurence of matched elements and returns boolean value
 var result1 = items.RemoveAll(lst => lst == 3);// Remove all the matched elements and returns count of removed element
 items.RemoveAt(3);//Removes the elements at the specified index

After you get from Eclipse the ugly CheckoutConflictException, the Eclipse-Merge Tool button is disabled.

Git need alle your files added to the Index for enable Merging.

So, to merge your Changes and commit them you need to add your files first to the index "Add to Index" and "Commit" them without "Push". Then you should see one pending pull and one pending push request in Eclipse. You see that in one up arrow and one down arrow.

If all conflict Files are in the commit, you can "pull" again. Then you will see something like:

\< < < < < < < HEAD Server Version \======= Local Version > > > > > > > branch 'master' of ....git

Then you either change it by the Merge-Tool, which is now enable or just do the merge by hand direct in the file. In the last step, you have to add the modified files again to the index and "Commit and Push" them.

Checking done!

document.location is an object, while document.location.href is a string. But the former has a toString method, so you can read from it as if it was a string and get the same value as document.location.href.

In some browsers - most modern ones, I think - you can also assign to document.location as if it were a string. According to the Mozilla documentation however, it is better to use window.location for this purpose as document.location was originally read-only and so may not be as widely supported.

            echo "Invalid date/time data detected";
        }

I am also newish to Java and just figured this out. You should create your own class which stores the string and integer, and then make a list of these objects. For instance (I am sure this code is imperfect, but better than arrayList):

class Stuff {
    private String label;
    private Integer value;

    // Constructor or setter
    public void Stuff(String label, Integer value) {
        if (label == null || value == null) {
            return;
        }
        this.label = label;
        this.value = value;
    }

    // getters

    public String getLabel() {
        return this.label;
    }

    public Integer getValue() {
        return this.value;
    }
}

Then in your code:

private ArrayList<Stuff> items = new ArrayList<Stuff>();
items.add(new Stuff(label, value));

For some reason ionden's solution didn't work for me.

1) Are you sure mod_rewrite module is enabled? Check phpinfo()

2) Your above rule assumes the URL starts with "folder". Is this correct? Did you acutally want to have folder in the URL? This would match a URL like:

/folder/thing -> /folder/thing.php

If you actually want

/thing -> /folder/thing.php

You need to drop the folder from the match expression.

I usually use this to route request to page without php (but yours should work which leads me to think that mod_rewrite may not be enabled):

RewriteRule ^([^/\.]+)/?$ $1.php  [L,QSA]

3) Assuming you are declaring your rules in an .htaccess file, does your installation allow for setting Options (AllowOverride) overrides in .htaccess files? Some shared hosts do not.

When the server finds an .htaccess file (as specified by AccessFileName) it needs to know which directives declared in that file can override earlier access information.

str_replace will do the trick thusly

$new_str = str_replace(' ', '', $old_str);

I found a solution to fix this.

Edit your /etc/phpmyadmin/config.inc.php file.

Find:

if (!empty($dbport) || $dbserver != 'localhost') {
        $cfg['Servers'][$i]['connect_type'] = 'tcp';
        $cfg['Servers'][$i]['port'] = $dbport;
    }

Add after:

$cfg['Servers'][$i]['pmadb'] = null; // Apurba

Restart your apache service and try. Hope it helps. Thanks.

I tried absolutely everything here and nothing worked. My project was in VS 2013. I have since upgraded to VS 2015 and have been creating all of my new applications in 2015 but loading, compiling, building etc all of my old apps that were built in 2013 in that version.

I ended up just loading the solution in 2015 and it resolved it for me.

Clone target repository same way like you cloning any other project:

git clone [email protected]:myuser/foo.git

Then install it in develop mode:

cd foo
pip install -e .

You can change anything you wan't and every code using foo package will use modified code.

There 2 benefits ot this solution:

1. You can install package in your home projects directory.
2. Package includes .git dir, so it's regular Git repository. You can push to your fork right away.

Helvetica Neue is a paid font, so you shouldn't @font-face it, as you'd be freely distributing a copyrighted font. It's included in Mac systems but not in windows/linux ones, so yes, plenty of your users wont have it installed. Anyway, you can use 'Arial Narrow' as a windows substitute, which is it's windows equivalent.

For a terse, pure flexbox option, group the left-aligned items and the right-aligned items:

<div class="wrap">
  <div>
    <span>One</span>
    <span>Two</span>
  </div>
  <div>Three</div>
</div>

and use space-between:

.wrap {
  display: flex;
  background: #ccc;
  justify-content: space-between;
}

This way you can group multiple items to the right(or just one).

Case sensitive: document.getElementById (notice the capital B).

Use the length property of the [String] type:

if ($dbUserName.length -gt 8) {
    Write-Output "Please enter more than 8 characters."
    $dbUserName = Read-Host "Re-enter database username"
}

Please note that you have to use -gt instead of > in your if condition. PowerShell uses the following comparison operators to compare values and test conditions:

• -eq = equals
• -ne = not equals
• -lt = less than
• -gt = greater than
• -le = less than or equals
• -ge = greater than or equals

Do you mean tmux window? Ctrl + b + , if you have C-b as send prefix (it's by default)

I had a similar problem, with a lot of help from the web and this post I made a small application, my target is VCD and SVCD and I don't delete the source but I reckon it will be fairly easy to adapt to your own needs.

It can convert 1 video and cut it or can convert all videos in a folder, rename them and put them in a subfolder /VCD

I also add a small interface, hope someone else find it useful!

I put the code and file in here btw: http://tequilaphp.wordpress.com/2010/08/27/learning-python-making-a-svcd-gui/

to set a div at position fixed you can use

width:100%;
height:50px; /* change me */

I don't think that there are any neat tricks you can do storing this as you can do for example with an MD5 hash.

I think your best bet is to store it as a CHAR(60) as it is always 60 chars long

HttpContext.Current.Request.Url.Host is returning the correct values. If you run it on www.somedomainname.com it will give you www.somedomainname.com. If you want to get the 5858 as well you need to use

HttpContext.Current.Request.Url.Port 

Here's my general-purpose function for this. It returns a list of file paths rather than filenames since I found that to be more useful. It has a few optional arguments that make it versatile. For instance, I often use it with arguments like pattern='*.txt' or subfolders=True.

import os
import fnmatch

def list_paths(folder='.', pattern='*', case_sensitive=False, subfolders=False):
    """Return a list of the file paths matching the pattern in the specified 
    folder, optionally including files inside subfolders.
    """
    match = fnmatch.fnmatchcase if case_sensitive else fnmatch.fnmatch
    walked = os.walk(folder) if subfolders else [next(os.walk(folder))]
    return [os.path.join(root, f)
            for root, dirnames, filenames in walked
            for f in filenames if match(f, pattern)]

This also happens when you use development docker compose like the below, in production. You don't want to be building images in production as that breaks the ideology of containers. We should be deploying images:

  web:
    build: .
    command: python manage.py runserver 0.0.0.0:8000
    volumes:
      - .:/code
    ports:
      - "8000:8000"

Change that to use the built image:

  web:
    command: /bin/bash run.sh
    image: registry.voxcloud.co.za:9000/dyndns_api_web:0.1
    ports:
      - "8000:8000"

Try the packaged pecl version instead (the advantage of the packaged installs is that they're easier to upgrade):

apt-get install php5-dev
pecl install pdo
pecl install pdo_pgsql

or, if you just need a driver for PHP, but that it doesn't have to be the PDO one:

apt-get install php5-pgsql

Otherwise, that message most likely means you need to install a more recent libpq package. You can check which version you have by running:

dpkg -s libpq-dev

The guarantees the standard gives you go like this:

1 == sizeof(char) <= sizeof(short) <= sizeof (int) <= sizeof(long) <= sizeof(long long)

So it's perfectly valid for sizeof (int) and sizeof (long) to be equal, and many platforms choose to go with this approach. You will find some platforms where int is 32 bits, long is 64 bits, and long long is 128 bits, but it seems very common for sizeof (long) to be 4.

(Note that long long is recognized in C from C99 onwards, but was normally implemented as an extension in C++ prior to C++11.)

If you are using Python selenium bindings, nowadays, there is an extension to selenium - selenium-requests:

Extends Selenium WebDriver classes to include the request function from the Requests library, while doing all the needed cookie and request headers handling.

Example:

from seleniumrequests import Firefox

webdriver = Firefox()
response = webdriver.request('POST', 'url here', data={"param1": "value1"})
print(response)

You could do this with an INSTEAD OF INSERT trigger on the table, that checks for the existance of the row and then updates/inserts depending on whether it exists already. There is an example of how to do this for SQL Server 2000+ on MSDN here:

CREATE TRIGGER IO_Trig_INS_Employee ON Employee
INSTEAD OF INSERT
AS
BEGIN
SET NOCOUNT ON
-- Check for duplicate Person. If no duplicate, do an insert.
IF (NOT EXISTS (SELECT P.SSN
      FROM Person P, inserted I
      WHERE P.SSN = I.SSN))
   INSERT INTO Person
      SELECT SSN,Name,Address,Birthdate
      FROM inserted
ELSE
-- Log attempt to insert duplicate Person row in PersonDuplicates table.
   INSERT INTO PersonDuplicates
      SELECT SSN,Name,Address,Birthdate,SUSER_SNAME(),GETDATE()
      FROM inserted
-- Check for duplicate Employee. If no duplicate, do an insert.
IF (NOT EXISTS (SELECT E.SSN
      FROM EmployeeTable E, inserted
      WHERE E.SSN = inserted.SSN))
   INSERT INTO EmployeeTable
      SELECT EmployeeID,SSN, Department, Salary
      FROM inserted
ELSE
--If duplicate, change to UPDATE so that there will not
--be a duplicate key violation error.
   UPDATE EmployeeTable
      SET EmployeeID = I.EmployeeID,
          Department = I.Department,
          Salary = I.Salary
   FROM EmployeeTable E, inserted I
   WHERE E.SSN = I.SSN
END

If I understand you correctly, you want to compose a multipart request manually from an HTTP/REST console. The multipart format is simple; a brief introduction can be found in the HTML 4.01 spec. You need to come up with a boundary, which is a string not found in the content, let’s say HereGoes. You set request header Content-Type: multipart/form-data; boundary=HereGoes. Then this should be a valid request body:

--HereGoes
Content-Disposition: form-data; name="myJsonString"
Content-Type: application/json

{"foo": "bar"}
--HereGoes
Content-Disposition: form-data; name="photo"
Content-Type: image/jpeg
Content-Transfer-Encoding: base64

<...JPEG content in base64...>
--HereGoes--

Textpad also works well at opening files that size. I have done it many times when having to deal with extremely large log files in the 3-5gb range. Also, using grep to pull out the worthwhile lines and then look at those works great.

If between two remote mongod instances, use

{ cloneCollection: "<collection>", from: "<hostname>", query: { <query> }, copyIndexes: <true|false> } 

See http://docs.mongodb.org/manual/reference/command/cloneCollection/

I think that this should work:

.element {
   -webkit-transition: all .3s;
   -moz-transition: all .3s;
   -o-transition: all .3s;
   transition: all .3s;
}

Depends on what you need the implementation to do well. Insertion order usually is not interesting so there is no need to maintain it so you can rearrange to get better performance.

For Maps it is usually HashMap and TreeMap that is used. By using hash codes, the entries can be put in small groups easy to search in. The TreeMap maintains a sorted order of the inserted entries at the cost of slower search, but easier to sort than a HashMap.

Have you tried moving your [(ngModel)] to the div instead of the switch in your HTML? I had the same error appear in my code and it was because I bound the model to a <mat-option> instead of a <mat-select>. Though I am not using form control.

[function.fopen]: failed to open stream

If you have access to your php.ini file, try enabling Fopen. Find the respective line and set it to be "on": & if in wp e.g localhost/wordpress/function.fopen in the php.ini :

allow_url_fopen = off
should bee this 
allow_url_fopen = On

And add this line below it:
allow_url_include = off
should bee this 
allow_url_include = on

They change it again. At this moment documentation does not fit actual situation.

Commonly all works as expected with one small difference. Login from Devices config now moves to Products -> Facebook Login.

So you need to:

• get your App id from headline,
• get Client Token from app Settings -> Advanced. There is also Native or desktop app? question/config. I turn it on.
• Add product (just click on Add product and then Get started on Facebook login. Move back to your app config, click to newly added Facebook login and you'll see your Login from Devices config.

Updated for Swift 5

preferredLayoutAttributesFittingAttributes renamed to preferredLayoutAttributesFitting and use auto sizing

Updated for Swift 4

systemLayoutSizeFittingSize renamed to systemLayoutSizeFitting

Updated for iOS 9

After seeing my GitHub solution break under iOS 9 I finally got the time to investigate the issue fully. I have now updated the repo to include several examples of different configurations for self sizing cells. My conclusion is that self sizing cells are great in theory but messy in practice. A word of caution when proceeding with self sizing cells.

TL;DR

Check out my GitHub project

Self sizing cells are only supported with flow layout so make sure thats what you are using.

There are two things you need to setup for self sizing cells to work.

1. Set estimatedItemSize on UICollectionViewFlowLayout

Flow layout will become dynamic in nature once you set the estimatedItemSize property.

self.flowLayout.estimatedItemSize = UICollectionViewFlowLayout.automaticSize

2. Add support for sizing on your cell subclass

This comes in 2 flavours; Auto-Layout or custom override of preferredLayoutAttributesFittingAttributes.

Create and configure cells with Auto Layout

I won't go to in to detail about this as there's a brilliant SO post about configuring constraints for a cell. Just be wary that Xcode 6 broke a bunch of stuff with iOS 7 so, if you support iOS 7, you will need to do stuff like ensure the autoresizingMask is set on the cell's contentView and that the contentView's bounds is set as the cell's bounds when the cell is loaded (i.e. awakeFromNib).

Things you do need to be aware of is that your cell needs to be more seriously constrained than a Table View Cell. For instance, if you want your width to be dynamic then your cell needs a height constraint. Likewise, if you want the height to be dynamic then you will need a width constraint to your cell.

Implement preferredLayoutAttributesFittingAttributes in your custom cell

When this function is called your view has already been configured with content (i.e. cellForItem has been called). Assuming your constraints have been appropriately set you could have an implementation like this:

//forces the system to do one layout pass
var isHeightCalculated: Bool = false

override func preferredLayoutAttributesFitting(_ layoutAttributes: UICollectionViewLayoutAttributes) -> UICollectionViewLayoutAttributes {
    //Exhibit A - We need to cache our calculation to prevent a crash.
    if !isHeightCalculated {
        setNeedsLayout()
        layoutIfNeeded()
        let size = contentView.systemLayoutSizeFitting(layoutAttributes.size)
        var newFrame = layoutAttributes.frame
        newFrame.size.width = CGFloat(ceilf(Float(size.width)))
        layoutAttributes.frame = newFrame
        isHeightCalculated = true
    }
    return layoutAttributes
}

NOTE On iOS 9 the behaviour changed a bit that could cause crashes on your implementation if you are not careful (See more here). When you implement preferredLayoutAttributesFittingAttributes you need to ensure that you only change the frame of your layout attributes once. If you don't do this the layout will call your implementation indefinitely and eventually crash. One solution is to cache the calculated size in your cell and invalidate this anytime you reuse the cell or change its content as I have done with the isHeightCalculated property.

Experience your layout

At this point you should have 'functioning' dynamic cells in your collectionView. I haven't yet found the out-of-the box solution sufficient during my tests so feel free to comment if you have. It still feels like UITableView wins the battle for dynamic sizing IMHO.

Caveats

Be very mindful that if you are using prototype cells to calculate the estimatedItemSize - this will break if your XIB uses size classes. The reason for this is that when you load your cell from a XIB its size class will be configured with Undefined. This will only be broken on iOS 8 and up since on iOS 7 the size class will be loaded based on the device (iPad = Regular-Any, iPhone = Compact-Any). You can either set the estimatedItemSize without loading the XIB, or you can load the cell from the XIB, add it to the collectionView (this will set the traitCollection), perform the layout, and then remove it from the superview. Alternatively you could also make your cell override the traitCollection getter and return the appropriate traits. It's up to you.

Let me know if I missed anything, hope I helped and good luck coding

Another great thing that I think no one has mentioned about Node.js is the amazing community, the package management system (npm) and the amount of modules that exist that you can include by simply including them in your package.json file.

We can use the below Methods to get the version Number of Oracle.

DBMS_OUTPUT.PUT_LINE(DBMS_DB_VERSION.VERSION || '.' || DBMS_DB_VERSION.RELEASE); 
END;

Method No : 2

SQL> select *
  2  from v$version;

I think your code is a bit too complicated and it needs more structure, because otherwise you'll be lost in all equations and operations. In the end this regression boils down to four operations:

1. Calculate the hypothesis h = X * theta
2. Calculate the loss = h - y and maybe the squared cost (loss^2)/2m
3. Calculate the gradient = X' * loss / m
4. Update the parameters theta = theta - alpha * gradient

In your case, I guess you have confused m with n. Here m denotes the number of examples in your training set, not the number of features.

Let's have a look at my variation of your code:

import numpy as np
import random

# m denotes the number of examples here, not the number of features
def gradientDescent(x, y, theta, alpha, m, numIterations):
    xTrans = x.transpose()
    for i in range(0, numIterations):
        hypothesis = np.dot(x, theta)
        loss = hypothesis - y
        # avg cost per example (the 2 in 2*m doesn't really matter here.
        # But to be consistent with the gradient, I include it)
        cost = np.sum(loss ** 2) / (2 * m)
        print("Iteration %d | Cost: %f" % (i, cost))
        # avg gradient per example
        gradient = np.dot(xTrans, loss) / m
        # update
        theta = theta - alpha * gradient
    return theta


def genData(numPoints, bias, variance):
    x = np.zeros(shape=(numPoints, 2))
    y = np.zeros(shape=numPoints)
    # basically a straight line
    for i in range(0, numPoints):
        # bias feature
        x[i][0] = 1
        x[i][1] = i
        # our target variable
        y[i] = (i + bias) + random.uniform(0, 1) * variance
    return x, y

# gen 100 points with a bias of 25 and 10 variance as a bit of noise
x, y = genData(100, 25, 10)
m, n = np.shape(x)
numIterations= 100000
alpha = 0.0005
theta = np.ones(n)
theta = gradientDescent(x, y, theta, alpha, m, numIterations)
print(theta)

At first I create a small random dataset which should look like this:

As you can see I also added the generated regression line and formula that was calculated by excel.

You need to take care about the intuition of the regression using gradient descent. As you do a complete batch pass over your data X, you need to reduce the m-losses of every example to a single weight update. In this case, this is the average of the sum over the gradients, thus the division by m.

The next thing you need to take care about is to track the convergence and adjust the learning rate. For that matter you should always track your cost every iteration, maybe even plot it.

If you run my example, the theta returned will look like this:

Iteration 99997 | Cost: 47883.706462
Iteration 99998 | Cost: 47883.706462
Iteration 99999 | Cost: 47883.706462
[ 29.25567368   1.01108458]

Which is actually quite close to the equation that was calculated by excel (y = x + 30). Note that as we passed the bias into the first column, the first theta value denotes the bias weight.

Yes, it is. And it is supported in all major browser:

var ts = Date.parse("date string");

The only difference is that this function returns milliseconds instead of seconds, so you need to divide the result by 1000.

Try moving the lapsList function out of your class and into your render function:

render() {
  const lapsList = this.state.laps.map((data) => {
    return (
      <View><Text>{data.time}</Text></View>
    )
  })

  return (
    <View style={styles.container}>
      <View style={styles.footer}>
        <View><Text>coucou test</Text></View>
        {lapsList}
      </View>
    </View>
  )
}

Here is the simple trick. Just copy and paste it.

Required no extra work. Thanks John Noel Bruno

this will be more efficient:

public static class StringExtension
{
    public static string clean(this string s)
    {
        return new StringBuilder(s)
              .Replace("&", "and")
              .Replace(",", "")
              .Replace("  ", " ")
              .Replace(" ", "-")
              .Replace("'", "")
              .Replace(".", "")
              .Replace("eacute;", "é")
              .ToString()
              .ToLower();
    }
}

I'll do my best to explain it here on simple terms, but be warned that this topic takes my students a couple of months to finally grasp. You can find more information on the Chapter 2 of the Data Structures and Algorithms in Java book.

There is no mechanical procedure that can be used to get the BigOh.

As a "cookbook", to obtain the BigOh from a piece of code you first need to realize that you are creating a math formula to count how many steps of computations get executed given an input of some size.

The purpose is simple: to compare algorithms from a theoretical point of view, without the need to execute the code. The lesser the number of steps, the faster the algorithm.

For example, let's say you have this piece of code:

int sum(int* data, int N) {
    int result = 0;               // 1

    for (int i = 0; i < N; i++) { // 2
        result += data[i];        // 3
    }

    return result;                // 4
}

This function returns the sum of all the elements of the array, and we want to create a formula to count the computational complexity of that function:

Number_Of_Steps = f(N)

So we have f(N), a function to count the number of computational steps. The input of the function is the size of the structure to process. It means that this function is called such as:

Number_Of_Steps = f(data.length)

The parameter N takes the data.length value. Now we need the actual definition of the function f(). This is done from the source code, in which each interesting line is numbered from 1 to 4.

There are many ways to calculate the BigOh. From this point forward we are going to assume that every sentence that doesn't depend on the size of the input data takes a constant C number computational steps.

We are going to add the individual number of steps of the function, and neither the local variable declaration nor the return statement depends on the size of the data array.

That means that lines 1 and 4 takes C amount of steps each, and the function is somewhat like this:

f(N) = C + ??? + C

The next part is to define the value of the for statement. Remember that we are counting the number of computational steps, meaning that the body of the for statement gets executed N times. That's the same as adding C, N times:

f(N) = C + (C + C + ... + C) + C = C + N * C + C

There is no mechanical rule to count how many times the body of the for gets executed, you need to count it by looking at what does the code do. To simplify the calculations, we are ignoring the variable initialization, condition and increment parts of the for statement.

To get the actual BigOh we need the Asymptotic analysis of the function. This is roughly done like this:

1. Take away all the constants C.
2. From f() get the polynomium in its standard form.
3. Divide the terms of the polynomium and sort them by the rate of growth.
4. Keep the one that grows bigger when N approaches infinity.

Our f() has two terms:

f(N) = 2 * C * N ^ 0 + 1 * C * N ^ 1

Taking away all the C constants and redundant parts:

f(N) = 1 + N ^ 1

Since the last term is the one which grows bigger when f() approaches infinity (think on limits) this is the BigOh argument, and the sum() function has a BigOh of:

O(N)

There are a few tricks to solve some tricky ones: use summations whenever you can.

As an example, this code can be easily solved using summations:

for (i = 0; i < 2*n; i += 2) {  // 1
    for (j=n; j > i; j--) {     // 2
        foo();                  // 3
    }
}

The first thing you needed to be asked is the order of execution of foo(). While the usual is to be O(1), you need to ask your professors about it. O(1) means (almost, mostly) constant C, independent of the size N.

The for statement on the sentence number one is tricky. While the index ends at 2 * N, the increment is done by two. That means that the first for gets executed only N steps, and we need to divide the count by two.

f(N) = Summation(i from 1 to 2 * N / 2)( ... ) = 
     = Summation(i from 1 to N)( ... )

The sentence number two is even trickier since it depends on the value of i. Take a look: the index i takes the values: 0, 2, 4, 6, 8, ..., 2 * N, and the second for get executed: N times the first one, N - 2 the second, N - 4 the third... up to the N / 2 stage, on which the second for never gets executed.

On formula, that means:

f(N) = Summation(i from 1 to N)( Summation(j = ???)(  ) )

Again, we are counting the number of steps. And by definition, every summation should always start at one, and end at a number bigger-or-equal than one.

f(N) = Summation(i from 1 to N)( Summation(j = 1 to (N - (i - 1) * 2)( C ) )

(We are assuming that foo() is O(1) and takes C steps.)

We have a problem here: when i takes the value N / 2 + 1 upwards, the inner Summation ends at a negative number! That's impossible and wrong. We need to split the summation in two, being the pivotal point the moment i takes N / 2 + 1.

f(N) = Summation(i from 1 to N / 2)( Summation(j = 1 to (N - (i - 1) * 2)) * ( C ) ) + Summation(i from 1 to N / 2) * ( C )

Since the pivotal moment i > N / 2, the inner for won't get executed, and we are assuming a constant C execution complexity on its body.

Now the summations can be simplified using some identity rules:

1. Summation(w from 1 to N)( C ) = N * C
2. Summation(w from 1 to N)( A (+/-) B ) = Summation(w from 1 to N)( A ) (+/-) Summation(w from 1 to N)( B )
3. Summation(w from 1 to N)( w * C ) = C * Summation(w from 1 to N)( w ) (C is a constant, independent of w)
4. Summation(w from 1 to N)( w ) = (N * (N + 1)) / 2

Applying some algebra:

f(N) = Summation(i from 1 to N / 2)( (N - (i - 1) * 2) * ( C ) ) + (N / 2)( C )

f(N) = C * Summation(i from 1 to N / 2)( (N - (i - 1) * 2)) + (N / 2)( C )

f(N) = C * (Summation(i from 1 to N / 2)( N ) - Summation(i from 1 to N / 2)( (i - 1) * 2)) + (N / 2)( C )

f(N) = C * (( N ^ 2 / 2 ) - 2 * Summation(i from 1 to N / 2)( i - 1 )) + (N / 2)( C )

=> Summation(i from 1 to N / 2)( i - 1 ) = Summation(i from 1 to N / 2 - 1)( i )

f(N) = C * (( N ^ 2 / 2 ) - 2 * Summation(i from 1 to N / 2 - 1)( i )) + (N / 2)( C )

f(N) = C * (( N ^ 2 / 2 ) - 2 * ( (N / 2 - 1) * (N / 2 - 1 + 1) / 2) ) + (N / 2)( C )

=> (N / 2 - 1) * (N / 2 - 1 + 1) / 2 = 

   (N / 2 - 1) * (N / 2) / 2 = 

   ((N ^ 2 / 4) - (N / 2)) / 2 = 

   (N ^ 2 / 8) - (N / 4)

f(N) = C * (( N ^ 2 / 2 ) - 2 * ( (N ^ 2 / 8) - (N / 4) )) + (N / 2)( C )

f(N) = C * (( N ^ 2 / 2 ) - ( (N ^ 2 / 4) - (N / 2) )) + (N / 2)( C )

f(N) = C * (( N ^ 2 / 2 ) - (N ^ 2 / 4) + (N / 2)) + (N / 2)( C )

f(N) = C * ( N ^ 2 / 4 ) + C * (N / 2) + C * (N / 2)

f(N) = C * ( N ^ 2 / 4 ) + 2 * C * (N / 2)

f(N) = C * ( N ^ 2 / 4 ) + C * N

f(N) = C * 1/4 * N ^ 2 + C * N

And the BigOh is:

O(N²)

I think the best way is:
a) Copy data into HDFS (if it is not already there)
b) Create external table over your CSV like this

CREATE EXTERNAL TABLE TableName (id int, name string)
ROW FORMAT DELIMITED   
FIELDS TERMINATED BY ',' 
LINES TERMINATED BY '\n'
STORED AS TEXTFILE
LOCATION 'place in HDFS';

c) You can start using TableName already by issuing queries to it.
d) if you want to insert data into other Hive table:

insert overwrite table finalTable select * from table name;

I've used these for a long time - no idea where they came from at this point... Note that the inputs and outputs, except for the angle in degrees, are in the range of 0 to 1.0.

This should be the Unix load average. Wikipedia has a nice article about this.

You should try. When you clear your Graphics you must choose color. SystemColors.Control is native color of form

Graphics g = pB.CreateGraphics();
g.Clear(SystemColors.Control);

This is the ASCII format.

Please consider that:

Some data (like URLs) can be sent over the Internet using the ASCII character-set. Since data often contain characters outside the ASCII set, so it has to be converted into a valid ASCII format.

To find it yourself, you can visit https://en.wikipedia.org/wiki/ASCII, there you can find big tables of characters. The one you are looking is in Control Characters table.

Digging to table you can find

Oct Dec Hex Name 012 10 0A Line Feed

In the html file you can use Dec and Hex representation of charters

The Dec is represented with 


The Hex is represented with &#x0A (or you can omit the leading zero &#xA)

There is a good converter at https://r12a.github.io/apps/conversion/ .

No, the link assigned to the containing <a> will be assigned to every elements inside it.

And, this is not the proper way. You can make a <a> behave like a <div>.

An Example ^[Demo]

CSS

a.divlink { 
     display:block;
     width:500px;
     height:500px; 
     float:left;
}

HTML

<div>
    <a class="divlink" href="yourlink.html">
         The text or elements inside the elements
    </a>
    <a class="divlink" href="yourlink2.html">
         Another text or element
    </a>
</div>

Note the potential for an out-of-range index with "i+3". You could do something like:

with open("file.txt", "r") as f:
    searchlines = f.readlines()
j=len(searchlines)-1
for i, line in enumerate(searchlines):
    if "searchphrase" in line: 
        k=min(i+3,j)
        for l in searchlines[i:k]: print l,
        print

Edit: maybe not necessary. I just tested some examples. x[y] will give errors if y is out of range, but x[y:z] doesn't seem to give errors for out of range values of y and z.

You can define your versionName and versionCode in your module's build.gradle file like this :

android {
    compileSdkVersion 19
    buildToolsVersion "19.0.1"

    defaultConfig {
        minSdkVersion 8
        targetSdkVersion 19
        versionCode 1
        versionName "1.0"
    }
    .... //Other Configuration
}

Try using another temporary pair:

pair<string,double> temp;
vector<pair<string,double>> revenue;

// Inside the loop
temp.first = "string";
temp.second = map[i].second;
revenue.push_back(temp);

in intelliJ IDEA go-lang plugin (and i assume in jetbrains Gogland) you can just set the test kind to file under run > edit configurations

You can use Map.

• A new data structure introduced in JavaScript ES6.
• Alternative to JavaScript Object for storing key/value pairs.
• Has useful methods for iteration over the key/value pairs.

var map = new Map();
map.set('name', 'John');
map.set('id', 11);

// Get the full content of the Map
console.log(map); // Map { 'name' => 'John', 'id' => 11 }

Get value of the Map using key

console.log(map.get('name')); // John 
console.log(map.get('id')); // 11

Get size of the Map

console.log(map.size); // 2

Check key exists in Map

console.log(map.has('name')); // true
console.log(map.has('age')); // false

Get keys

console.log(map.keys()); // MapIterator { 'name', 'id' }

Get values

console.log(map.values()); // MapIterator { 'John', 11 }

Get elements of the Map

for (let element of map) {
  console.log(element);
}

// Output:
// [ 'name', 'John' ]
// [ 'id', 11 ]

Print key value pairs

for (let [key, value] of map) {
  console.log(key + " - " + value);
}

// Output: 
// name - John
// id - 11

Print only keys of the Map

for (let key of map.keys()) {
  console.log(key);
}

// Output:
// name
// id

Print only values of the Map

for (let value of map.values()) {
  console.log(value);
}

// Output:
// John
// 11

Copy the CSV file to /tmp

For me this solved the issue.

Here is a small example that shows the usefulness of the Action delegate

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        Action<String> print = new Action<String>(Program.Print);

        List<String> names = new List<String> { "andrew", "nicole" };

        names.ForEach(print);

        Console.Read();
    }

    static void Print(String s)
    {
        Console.WriteLine(s);
    }
}

Notice that the foreach method iterates the collection of names and executes the print method against each member of the collection. This a bit of a paradigm shift for us C# developers as we move towards a more functional style of programming. (For more info on the computer science behind it read this: http://en.wikipedia.org/wiki/Map_(higher-order_function).

Now if you are using C# 3 you can slick this up a bit with a lambda expression like so:

using System;
using System.Collections.Generic;

class Program
{
    static void Main()
    {
        List<String> names = new List<String> { "andrew", "nicole" };

        names.ForEach(s => Console.WriteLine(s));

        Console.Read();
    }
}

If you also have documents that don't have the key, you can use:

ME.find({ pictures: { $exists: true, $not: {$size: 0} } })

MongoDB don't use indexes if $size is involved, so here is a better solution:

ME.find({ pictures: { $exists: true, $ne: [] } })

Since MongoDB 2.6 release, you can compare with the operator $gt but could lead to unexpected results (you can find a detailled explanation in this answer):

ME.find({ pictures: { $gt: [] } })

Try this

boxValue = boxValue.replace(/[^0-9\.]/g,"");

This Regular Expression will allow only digits and dots in the value of text box.

You could also print out the unique value in "file" using the cat command by piping to sort and uniq

cat file | sort | uniq -u

The only option I have found to do this is find some exact wording and put that under the "Has the words" option. Its not the best option, but it works.

One thing I find that is often missing from these is an ability to look up row locks. At least on the larger databases I have worked on, row locks are not shown in pg_locks (if they were, pg_locks would be much, much larger and there isn't a real data type to show the locked row in that view properly).

I don't know that there is a simple solution to this but usually what I do is look at the table where the lock is waiting and search for rows where the xmax is less than the transaction id present there. That usually gives me a place to start, but it is a bit hands-on and not automation friendly.

Note that shows you uncommitted writes on rows on those tables. Once committed, the rows are not visible in the current snapshot. But for large tables, that is a pain.

For my case, I received the same error after creating an empty Web Api project.

I solved it by editing RouteConfig.cs in the App_Start folder :)

I replaced the line of code reading :-

defaults: new { action = "Index", id = UrlParameter.Optional }

with the following :-

defaults: new { controller = "Index", action = "Index", id = UrlParameter.Optional }

Notice I just had to specify the Controller whose index action I would like to invoke first.

Well all the above responses didn't solve my case (as I wanted) e.g.

• Enabling directory browsing from web.config just listed all files and folders in my project just like php would do when you don't have an index file
• Setting defaultDocument also didn't work for me somehow still got the HTTP Error 403.14 (Still have no idea why)

If there may be anyone in similar circumstances as mine then give this a try.

You can create an extension method

static class MyExtensions
{
    internal static string Repeat(this char c, int n)
    {
        return new string(c, n);
    }
}

Then you can use it like this

Console.WriteLine('\t'.Repeat(10));

Null is similar to zero pointer in C++. So it is a reference which not pointing to any value.

DBNull.Value is completely different and is a constant which is returned when a field value contains NULL.

I received this error when I copied a class object using JSON.parse and JSON.stringify() which removed the function like:

class Rectangle {
  constructor(height, width) {
    this.height = height;
    this.width = width;
  }
  // Method
  calcArea() {
    return this.height * this.width;
  }
}

const square = new Rectangle(10, 10);

console.log('area of square: ', square.calcArea());

const squareCopy = JSON.parse(JSON.stringify(square));

// Will throw an exception since calcArea() is no longer function 
console.log('area of square copy: ', squareCopy.calcArea());

Another way which could make sense for the given situation is

BigDecimal newBD = oldBD.setScale(2);

I just say this because in some cases when it comes to money going beyond 2 decimal places does not make sense. Taking this a step further, this could lead to

String displayString = oldBD.setScale(2).toPlainString();

but I merely wanted to highlight the setScale method (which can also take a second rounding mode argument to control how that last decimal place is handled. In some situations, Java forces you to specify this rounding method).

A URL that starts with the URL scheme and scheme specific part (http://, https://, ftp://, etc.) is an absolute URL.

Any other URL is a relative URL and needs a base URL the relative URL is resolved from (and thus depend on) that is the URL of the resource the reference is used in if not declared otherwise.

Take a look at RFC 2396 – Appendix C for examples of resolving relative URLs.

Please note: There is a difference between using String[] to StringBuilder[].

In String - if you change the String, the other arrays we have copied (by CopyTo or Clone) that points to the same string will not change, but the original String array will point to a new String, however, if we use a StringBuilder in an array, the String pointer will not change, therefore, it will affect all the copies we have made for this array. For instance:

public void test()
{
    StringBuilder[] sArrOr = new StringBuilder[1];
    sArrOr[0] = new StringBuilder();
    sArrOr[0].Append("hello");
    StringBuilder[] sArrClone = (StringBuilder[])sArrOr.Clone();
    StringBuilder[] sArrCopyTo = new StringBuilder[1];
    sArrOr.CopyTo(sArrCopyTo,0);
    sArrOr[0].Append(" world");

    Console.WriteLine(sArrOr[0] + " " + sArrClone[0] + " " + sArrCopyTo[0]);
    //Outputs: hello world hello world hello world

    //Same result in int[] as using String[]
    int[] iArrOr = new int[2];
    iArrOr[0] = 0;
    iArrOr[1] = 1;
    int[] iArrCopyTo = new int[2];
    iArrOr.CopyTo(iArrCopyTo,0);
    int[] iArrClone = (int[])iArrOr.Clone();
    iArrOr[0]++;
    Console.WriteLine(iArrOr[0] + " " + iArrClone[0] + " " + iArrCopyTo[0]);
   // Output: 1 0 0
}

when reimporting your keys from the old keyring, you need to specify the command:

gpg --allow-secret-key-import --import <keyring>

otherwise it will only import the public keys, not the private keys.

I suspect you're only reporting the last error in a stack like this:

ORA-04068: existing state of packages has been discarded
ORA-04061: existing state of package body "schema.package" has been invalidated
ORA-04065: not executed, altered or dropped package body "schema.package"
ORA-06508: PL/SQL: could not find program unit being called: "schema.package"

If so, that's because your package is stateful:

The values of the variables, constants, and cursors that a package declares (in either its specification or body) comprise its package state. If a PL/SQL package declares at least one variable, constant, or cursor, then the package is stateful; otherwise, it is stateless.

When you recompile the state is lost:

If the body of an instantiated, stateful package is recompiled (either explicitly, with the "ALTER PACKAGE Statement", or implicitly), the next invocation of a subprogram in the package causes Oracle Database to discard the existing package state and raise the exception ORA-04068.

After PL/SQL raises the exception, a reference to the package causes Oracle Database to re-instantiate the package, which re-initializes it...

You can't avoid this if your package has state. I think it's fairly rare to really need a package to be stateful though, so you should revisit anything you have declared in the package, but outside a function or procedure, to see if it's really needed at that level. Since you're on 10g though, that includes constants, not just variables and cursors.

But the last paragraph from the quoted documentation means that the next time you reference the package in the same session, you won't get the error and it will work as normal (until you recompile again).

I was having trouble installing tensorflow with python 3.7 and followed these instructions to have a virtual environment setup with python3.6 and got it working

Download the Python3.6 tgz file from the official website (eg. Python-3.6.6.tgz)
Unpack it with tar -xvzf Python-3.6.6.tgz
cd Python-3.6.6
run ./configure
run make altinstall to install it (install vs altinstall explanation here 

setting up python3.6 virtual environment for tensorflow

If you are using jupyter notebook or jupyter lab this can be helpful to choose the right virtual environment

python -m venv projectname
source projectname/bin/activate
pip install ipykernel
ipython kernel install --user --name=projectname

At this point, you can start jupyter, create a new notebook and select the kernel that lives inside your environment.

Hope this helps

BundleConfig is nothing more than bundle configuration moved to separate file. It used to be part of app startup code (filters, bundles, routes used to be configured in one class)

To add this file, first you need to add the Microsoft.AspNet.Web.Optimization nuget package to your web project:

Install-Package Microsoft.AspNet.Web.Optimization

Then under the App_Start folder create a new cs file called BundleConfig.cs. Here is what I have in my mine (ASP.NET MVC 5, but it should work with MVC 4):

using System.Web;
using System.Web.Optimization;

namespace CodeRepository.Web
{
    public class BundleConfig
    {
        // For more information on bundling, visit http://go.microsoft.com/fwlink/?LinkId=301862
        public static void RegisterBundles(BundleCollection bundles)
        {
            bundles.Add(new ScriptBundle("~/bundles/jquery").Include(
                        "~/Scripts/jquery-{version}.js"));

            bundles.Add(new ScriptBundle("~/bundles/jqueryval").Include(
                        "~/Scripts/jquery.validate*"));

            // Use the development version of Modernizr to develop with and learn from. Then, when you're
            // ready for production, use the build tool at http://modernizr.com to pick only the tests you need.
            bundles.Add(new ScriptBundle("~/bundles/modernizr").Include(
                        "~/Scripts/modernizr-*"));

            bundles.Add(new ScriptBundle("~/bundles/bootstrap").Include(
                      "~/Scripts/bootstrap.js",
                      "~/Scripts/respond.js"));

            bundles.Add(new StyleBundle("~/Content/css").Include(
                      "~/Content/bootstrap.css",
                      "~/Content/site.css"));
        }
    }
}

Then modify your Global.asax and add a call to RegisterBundles() in Application_Start():

using System.Web.Optimization;

protected void Application_Start()
{
    AreaRegistration.RegisterAllAreas();
    RouteConfig.RegisterRoutes(RouteTable.Routes);
    BundleConfig.RegisterBundles(BundleTable.Bundles);
}

You can just convert everything to lowercase for the purposes of sorting:

SELECT * FROM NOTES ORDER BY LOWER(title);

If you want to make sure that the uppercase ones still end up ahead of the lowercase ones, just add that as a secondary sort:

SELECT * FROM NOTES ORDER BY LOWER(title), title;

Response status comes as second parameter in callback, (from docs):

// Simple GET request example :
$http.get('/someUrl').
  success(function(data, status, headers, config) {
    // this callback will be called asynchronously
    // when the response is available
  }).
  error(function(data, status, headers, config) {
    // called asynchronously if an error occurs
    // or server returns response with an error status.
  });

@Html.Partial("nameOfPartial", Model)

Update

protected string RenderPartialViewToString(string viewName, object model)
{
    if (string.IsNullOrEmpty(viewName))
        viewName = ControllerContext.RouteData.GetRequiredString("action");

    ViewData.Model = model;

    using (StringWriter sw = new StringWriter()) {
        ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
        ViewContext viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
        viewResult.View.Render(viewContext, sw);

        return sw.GetStringBuilder().ToString();
    }
}

If you want to be able to control which files are selected from the command line, I managed to do this for Angular 7.

In summary, you need to install @angular-devkit/build-angular:browser and then create a custom webpack plugin to pass the test file regex through. For example:

angular.json - change the test builder from @angular-devkit/build-angular:browser and set a custom config file:

...

        "test": {
          "builder": "@angular-builders/custom-webpack:browser",
          "options": {
            "customWebpackConfig": {
              "path": "./extra-webpack.config.js"
            },
...

extra-webpack.config.js - create a webpack configuration that reads the regex from the command line:

const webpack = require('webpack');
const FILTER = process.env.KARMA_FILTER;
let KARMA_SPEC_FILTER = '/.spec.ts$/';
if (FILTER) {
  KARMA_SPEC_FILTER = `/${FILTER}.spec.ts$/`;
}
module.exports = {
  plugins: [new webpack.DefinePlugin({KARMA_SPEC_FILTER})]
}

test.ts - edit the spec

...
// Then we find all the tests.
declare const KARMA_CONTEXT_SPEC: any;
const context = require.context('./', true, KARMA_CONTEXT_SPEC);

Then use as follows to override the default:

KARMA_FILTER='somefile-.*\.spec\.ts$' npm run test

I documented the backstory here, apologies in advance for types and mis-links. Credit to the answer above by @Aish-Anu for pointing me in the right direction.

Add in in pom.xml give the following plugin:

<plugin>
  <artifactId>maven-surefire-plugin</artifactId>
  <version>2.10</version>
  <configuration>
    <useFile>false</useFile>
  </configuration>
</plugin>

Open up terminal first and then go to directory of web server

cd /Library/WebServer/Documents

and then type this and what you will do is you will give read and write permission

sudo chmod -R o+w /Library/WebServer/Documents

This will surely work!

I tried above all and end-up with few changes which I would like to share. Here's the code which works for me (find the attached screenshot):

<div class="input-group">
    <input type="text" class="form-control" placeholder="Search text">
    <span class="input-group-btn" style="width:0;">
        <button class="btn btn-default" type="button">Go!</button>
    </span>
</div>

If you want to see it working, just use below code in you editor:

<html>
    <head>
        <link type='text/css' rel='stylesheet' href='https://maxcdn.bootstrapcdn.com/bootstrap/3.0.0/css/bootstrap.min.css' />
    </head>
    <body>
        <div class="container body-content">
            <div class="form-horizontal">
              <div class="input-group">
                  <input type="text" class="form-control" placeholder="Search text">
                  <span class="input-group-btn" style="width:0;">
                      <button class="btn btn-default" type="button">Go!</button>
                  </span>
              </div>
            </div>
        </div>
    </body>
</html>

Hope this helps.

This is probably because an empty line at the end of your input file.

Try this:

for x in f:
    try:
        print int(x.strip(),16)
    except ValueError:
        print "Invalid input:", x

Similar situation for following configuration:

• Windows Server 2012 R2 Standard
• MS SQL server 2008 (tested also SQL 2012)
• Oracle 10g client (OracleDB v8.1.7)
• MSDAORA provider
• Error ID: 7302

My solution:

• Install 32bit MS SQL Server (64bit MSDAORA doesn't exist)
• Install 32bit Oracle 10g 10.2.0.5 patch (set W7 compatibility on setup.exe)
• Restart SQL services
• Check Allow in process in MSDAORA provider
• Test linked oracle server connection

Implementations

Although the reference implementation of reStructuredText is written in Python, there are reStructuredText parsers in other languages too.

Python - Docutils

The main distribution of reStructuredText is the Python Docutils package. It contains several conversion tools:

• rst2html - from reStructuredText to HTML
• rst2xml - from reStructuredText to XML
• rst2latex - from reStructuredText to LaTeX
• rst2odt - from reStructuredText to ODF Text (word processor) document.
• rst2s5 - from reStructuredText to S5, a Simple Standards-based Slide Show System
• rst2man - from reStructuredText to Man page

Haskell - Pandoc

Pandoc is a Haskell library for converting from one markup format to another, and a command-line tool that uses this library. It can read Markdown and (subsets of) reStructuredText, HTML, and LaTeX, and it can write Markdown, reStructuredText, HTML, LaTeX, ConTeXt, PDF, RTF, DocBook XML, OpenDocument XML, ODT, GNU Texinfo, MediaWiki markup, groff man pages, and S5 HTML slide shows.

There is an Pandoc online tool (POT) to try this library. Unfortunately, compared to the reStructuredText online renderer (ROR),

• POT truncates input rather more shortly. The POT user must render input in chunks that could be rendered whole by the ROR.
• POT output lacks the helpful error messages displayed by the ROR (and generated by docutils)

Java - JRst

JRst is a Java reStructuredText parser. It can currently output HTML, XHTML, DocBook xdoc and PDF, BUT seems to have serious problems: neither PDF or (X)HTML generation works using the current full download, result pages in (X)HTML are empty and PDF generation fails on IO problems with XSL files (not bundled??). Note that the original JRst has been removed from the website; a fork is found on GitHub.

Scala - Laika

Laika is a new library for transforming markup languages to other output formats. Currently it supports input from Markdown and reStructuredText and produce HTML output. The library is written in Scala but should be also usable from Java.

Perl

• Text::Restructured - Perl implementation of reStructuredText parser
• Dotiac::DTL::Addon::markup - Filters to work with common markup languages - support reStructuredText
• Pod::POM::View::Restructured - View for Pod::POM that outputs reStructuredText

PHP

• Gregwar/RST - A mature PHP5.3 parser with tests
• php-restructuredtext - A simple, incomplete (but functional) implementation

C#/.NET

• reStructuredText for ANTLR - A C# based parser with tests (in progress). It also provides the language server behind reStructuredText extension for Visual Studio Code.

Nim/C

The Nim compiler features the commands rst2htmland rst2tex which transform reStructuredText files to HTML and TeX files. The standard library provides the following modules (used by the compiler) to handle reStructuredText files programmatically:

• rst - implements a reStructuredText parser
• rstast - implements an AST for the reStructuredText parser
• rstgen - implements a generator of HTML/Latex from reStructuredText

Other 3rd party converters

Most (but not all) of these tools are based on Docutils (see above) and provide conversion to or from formats that might not be supported by the main distribution.

From reStructuredText

• restview - This pip-installable python package requires docutils, which does the actual rendering. restview's major ease-of-use feature is that, when you save changes to your document(s), it automagically re-renders and re-displays them. restview
  1. starts a small web server
  2. calls docutils to render your document(s) to HTML
  3. calls your device's browser to display the output HTML.
• rst2pdf - from reStructuredText to PDF
• rst2odp - from reStructuredText to ODF Presentation
• rst2beamer - from reStructuredText to LaTeX beamer Presentation class
• Wikir - from reStructuredText to a Google (and possibly other) Wiki formats
• rst2qhc - Convert a collection of reStructuredText files into a Qt (toolkit) Help file and (optional) a Qt Help Project file

To reStructuredText

• xml2rst is an XSLT script to convert Docutils internal XML representation (back) to reStructuredText
• Pandoc (see above) can also convert from Markdown, HTML and LaTeX to reStructuredText
• db2rst is a simple and limited DocBook to reStructuredText translator
• pod2rst - convert .pod files to reStructuredText files

Extensions

Some projects use reStructuredText as a baseline to build on, or provide extra functionality extending the utility of the reStructuredText tools.

Sphinx

The Sphinx documentation generator translates a set of reStructuredText source files into various output formats, automatically producing cross-references, indices etc.

rest2web

rest2web is a simple tool that lets you build your website from a single template (or as many as you want), and keep the contents in reStructuredText.

Pygments

Pygments is a generic syntax highlighter for general use in all kinds of software such as forum systems, Wikis or other applications that need to prettify source code. See Using Pygments in reStructuredText documents.

Free Editors

While any plain text editor is suitable to write reStructuredText documents, some editors have better support than others.

Emacs

The Emacs support via rst-mode comes as part of the Docutils package under /docutils/tools/editors/emacs/rst.el

Vim

The vim-common package for that comes with most GNU/Linux distributions has reStructuredText syntax highlight and indentation support of reStructuredText out of the box:

• reStructuredText syntax highlighting mode for vim
• VST (Vim reStructured Text) is a plugin for Vim7 with folding for reStructuredText
• Riv.vim - fresh vim plugin for authoring rst and Sphinx doc
• Previm: Vim plugin for live previewing of reStructuredText and other mark up documents

Jed

There is a rst mode for the Jed programmers editor.

gedit

gedit, the official text editor of the GNOME desktop environment. There is a gedit reStructuredText plugin.

Geany

Geany, a small and lightweight Integrated Development Environment include support for reStructuredText from version 0.12 (October 10, 2007).

Leo

Leo, an outlining editor for programmers, supports reStructuredText via rst-plugin or via "@auto-rst" nodes (it's not well-documented, but @auto-rst nodes allow editing rst files directly, parsing the structure into the Leo outline).

It also provides a way to preview the resulting HTML, in a "viewrendered" pane.

FTE

The FTE Folding Text Editor - a free (licensed under the GNU GPL) text editor for developers. FTE has a mode for reStructuredText support. It provides color highlighting of basic RSTX elements and special menu that provide easy way to insert most popular RSTX elements to a document.

PyK

PyK is a successor of PyEdit and reStInPeace, written in Python with the help of the Qt4 toolkit.

Eclipse

The Eclipse IDE with the ReST Editor plug-in provides support for editing reStructuredText files.

NoTex

NoTex is a browser based (general purpose) text editor, with integrated project management and syntax highlighting. Plus it enables to write books, reports, articles etc. using rST and convert them to LaTex, PDF or HTML. The PDF files are of high publication quality and are produced via Sphinx with the Texlive LaTex suite.

Notepad++

Notepad++ is a general purpose text editor for Windows. It has syntax highlighting for many languages built-in and support for reStructuredText via a user defined language for reStructuredText.

Visual Studio Code

Visual Studio Code is a general purpose text editor for Windows/macOS/Linux. It has syntax highlighting for many languages built-in and supports reStructuredText via an extension from LeXtudio.

Dedicated reStructuredText Editors

• ReSTedit by Dinu Gherman and Bill Bumgarner
• Rest in Peace
• Enthought Tool Suite editor
• ReText a cross platform program that works like Marked.
• RSTPad a standalone cross-platform editor with live preview

Proprietary editors

Sublime Text

Sublime Text is a completely customizable and extensible source code editor available for Windows, OS X, and Linux. Registration is required for long-term use, but all functions are available in the unregistered version, with occasional reminders to purchase a license. Versions 2 and 3 (currently in beta) support reStructuredText syntax highlighting by default, and several plugins are available through the package manager Package Control to provide snippets and code completion, additional syntax highlighting, conversion to/from RST and other formats, and HTML preview in the browser.

BBEdit / TextWrangler

BBEdit (and its free variant TextWrangler) for Mac can syntax-highlight reStructuredText using this codeless language module.

TextMate

TextMate, a proprietary general-purpose GUI text editor for Mac OS X, has a bundle for reStructuredText.

Intype

Intype is a proprietary text editor for Windows, that support reStructuredText out of the box.

E Text Editor

E is a proprietary Text Editor licensed under the "Open Company License". It supports TextMate's bundles, so it should support reStructuredText the same way TextMate does.

PyCharm

PyCharm (and other IntelliJ platform IDEs?) has ReST/Sphinx support (syntax highlighting, autocomplete and preview).)

Wiki

here are some Wiki programs that support the reStructuredText markup as the native markup syntax, or as an add-on:

MediaWiki

MediaWiki reStructuredText extension allows for reStructuredText markup in MediaWiki surrounded by <rst> and </rst>.

MoinMoin

MoinMoin is an advanced, easy to use and extensible WikiEngine with a large community of users. Said in a few words, it is about collaboration on easily editable web pages.

It does not support authorship indication, versioning, hierarchy, chrome/framing/templating or styling. It leverages docutils/reStructuredText as the wiki syntax. As such, it's under 200 lines of code, and in a single file. You put it in a directory and it runs.

ikiwiki

Ikiwiki is a wiki compiler. It converts wiki pages into HTML pages suitable for publishing on a website. Ikiwiki stores pages and history in a revision control system such as Subversion or Git.

It's very easy. Try the below code

$(document).ready(function(){
  var hashValue = location.hash.replace(/^#/, '');  
  //do something with the value here  
});

In XML values in text() nodes.

If we write this

<numbers>1,2,3</numbers>

in element "numbers" will be one text() node with value "1,2,3".

Native way to get many text() nodes in element is insert nodes of other types in text.

Other available types is element or comment() node.

Split with element node:

<numbers>3<_/>2<_/>1</numbers>

Split with comment() node:

<numbers>3<!---->2<!---->1</numbers>

We can select this values by this XPath

//numbers/text()

Select value by index

//numbers/text()[3]

Will return text() node with value "1"

Your "bad" output is UTF-8 displayed as CP1252.

On Windows, many editors assume the default ANSI encoding (CP1252 on US Windows) instead of UTF-8 if there is no byte order mark (BOM) character at the start of the file. While a BOM is meaningless to the UTF-8 encoding, its UTF-8-encoded presence serves as a signature for some programs. For example, Microsoft Office's Excel requires it even on non-Windows OSes. Try:

df.to_csv('file.csv',encoding='utf-8-sig')

That encoder will add the BOM.

SELECT *
FROM
(
SELECT [Period], [Account], [Value]
FROM TableName
) AS source
PIVOT
(
    MAX([Value])
    FOR [Period] IN ([2000], [2001], [2002])
) as pvt

Another way,

SELECT ACCOUNT,
      MAX(CASE WHEN Period = '2000' THEN Value ELSE NULL END) [2000],
      MAX(CASE WHEN Period = '2001' THEN Value ELSE NULL END) [2001],
      MAX(CASE WHEN Period = '2002' THEN Value ELSE NULL END) [2002]
FROM tableName

YES YOU CAN.

In your stored procedure, you fill the table @tbRetour.

At the very end of your stored procedure, you write:

SELECT * FROM @tbRetour 

To execute the stored procedure, you write:

USE [...]
GO

DECLARE @return_value int

EXEC @return_value = [dbo].[getEnregistrementWithDetails]
@id_enregistrement_entete = '(guid)'

GO

You can use Javascript to get the viewport width and height. Then pass the values back via a hidden form input or ajax.

At its simplest

var width = $(window).width();
var height = $(window).height();

Complete method using hidden form inputs

Assuming you have: JQuery framework.

First, add these hidden form inputs to store the width and height until postback.

<asp:HiddenField ID="width" runat="server" />
<asp:HiddenField ID="height" runat="server" />

Next we want to get the window (viewport) width and height. JQuery has two methods for this, aptly named width() and height().

Add the following code to your .aspx file within the head element.

<script type="text/javascript">
$(document).ready(function() {

    $("#width").val() = $(window).width();
    $("#height").val() = $(window).height();    

});
</script>

Result

This will result in the width and height of the browser window being available on postback. Just access the hidden form inputs like this:

var TheBrowserWidth = width.Value;
var TheBrowserHeight = height.Value;

This method provides the height and width upon postback, but not on the intial page load.

Note on UpdatePanels: If you are posting back via UpdatePanels, I believe the hidden inputs need to be within the UpdatePanel.

Alternatively you can post back the values via an ajax call. This is useful if you want to react to window resizing.

Update for jquery 3.1.1

I had to change the JavaScript to:

$("#width").val($(window).width());
$("#height").val($(window).height());

It depends on your requirements.

Page Load : Perform actions common to all requests, such as setting up a database query. At this point, server controls in the tree are created and initialized, the state is restored, and form controls reflect client-side data. See Handling Inherited Events.

i use $.each of jquery but you can make it with a for loop, an improvement is this:

        //.ArraySort(array)
        /* Sort an array
         */
        ArraySort = function(array, sortFunc){
              var tmp = [];
              var aSorted=[];
              var oSorted={};

              for (var k in array) {
                if (array.hasOwnProperty(k)) 
                    tmp.push({key: k, value:  array[k]});
              }

              tmp.sort(function(o1, o2) {
                    return sortFunc(o1.value, o2.value);
              });                     

              if(Object.prototype.toString.call(array) === '[object Array]'){
                  $.each(tmp, function(index, value){
                      aSorted.push(value.value);
                  });
                  return aSorted;                     
              }

              if(Object.prototype.toString.call(array) === '[object Object]'){
                  $.each(tmp, function(index, value){
                      oSorted[value.key]=value.value;
                  });                     
                  return oSorted;
              }               
     };

So now you can do

    console.log("ArraySort");
    var arr1 = [4,3,6,1,2,8,5,9,9];
    var arr2 = {'a':4, 'b':3, 'c':6, 'd':1, 'e':2, 'f':8, 'g':5, 'h':9};
    var arr3 = {a: 'green', b: 'brown', c: 'blue', d: 'red'};
    var result1 = ArraySort(arr1, function(a,b){return a-b});
    var result2 = ArraySort(arr2, function(a,b){return a-b});
    var result3 = ArraySort(arr3, function(a,b){return a>b});
    console.log(result1);
    console.log(result2);       
    console.log(result3);

There are multiple aspects to argument overloading in Javascript:

1. Variable arguments - You can pass different sets of arguments (in both type and quantity) and the function will behave in a way that matches the arguments passed to it.

2. Default arguments - You can define a default value for an argument if it is not passed.

3. Named arguments - Argument order becomes irrelevant and you just name which arguments you want to pass to the function.

Below is a section on each of these categories of argument handling.

Variable Arguments

Because javascript has no type checking on arguments or required qty of arguments, you can just have one implementation of myFunc() that can adapt to what arguments were passed to it by checking the type, presence or quantity of arguments.

jQuery does this all the time. You can make some of the arguments optional or you can branch in your function depending upon what arguments are passed to it.

In implementing these types of overloads, you have several different techniques you can use:

1. You can check for the presence of any given argument by checking to see if the declared argument name value is undefined.
2. You can check the total quantity or arguments with arguments.length.
3. You can check the type of any given argument.
4. For variable numbers of arguments, you can use the arguments pseudo-array to access any given argument with arguments[i].

Here are some examples:

Let's look at jQuery's obj.data() method. It supports four different forms of usage:

obj.data("key");
obj.data("key", value);
obj.data();
obj.data(object);

Each one triggers a different behavior and, without using this dynamic form of overloading, would require four separate functions.

Here's how one can discern between all these options in English and then I'll combine them all in code:

// get the data element associated with a particular key value
obj.data("key");

If the first argument passed to .data() is a string and the second argument is undefined, then the caller must be using this form.

// set the value associated with a particular key
obj.data("key", value);

If the second argument is not undefined, then set the value of a particular key.

// get all keys/values
obj.data();

If no arguments are passed, then return all keys/values in a returned object.

// set all keys/values from the passed in object
obj.data(object);

If the type of the first argument is a plain object, then set all keys/values from that object.

Here's how you could combine all of those in one set of javascript logic:

 // method declaration for .data()
 data: function(key, value) {
     if (arguments.length === 0) {
         // .data()
         // no args passed, return all keys/values in an object
     } else if (typeof key === "string") {
         // first arg is a string, look at type of second arg
         if (typeof value !== "undefined") {
             // .data("key", value)
             // set the value for a particular key
         } else {
             // .data("key")
             // retrieve a value for a key
         }
     } else if (typeof key === "object") {
         // .data(object)
         // set all key/value pairs from this object
     } else {
         // unsupported arguments passed
     }
 },

The key to this technique is to make sure that all forms of arguments you want to accept are uniquely identifiable and there is never any confusion about which form the caller is using. This generally requires ordering the arguments appropriately and making sure that there is enough uniqueness in the type and position of the arguments that you can always tell which form is being used.

For example, if you have a function that takes three string arguments:

obj.query("firstArg", "secondArg", "thirdArg");

You can easily make the third argument optional and you can easily detect that condition, but you cannot make only the second argument optional because you can't tell which of these the caller means to be passing because there is no way to identify if the second argument is meant to be the second argument or the second argument was omitted so what's in the second argument's spot is actually the third argument:

obj.query("firstArg", "secondArg");
obj.query("firstArg", "thirdArg");

Since all three arguments are the same type, you can't tell the difference between different arguments so you don't know what the caller intended. With this calling style, only the third argument can be optional. If you wanted to omit the second argument, it would have to be passed as null (or some other detectable value) instead and your code would detect that:

obj.query("firstArg", null, "thirdArg");

Here's a jQuery example of optional arguments. both arguments are optional and take on default values if not passed:

clone: function( dataAndEvents, deepDataAndEvents ) {
    dataAndEvents = dataAndEvents == null ? false : dataAndEvents;
    deepDataAndEvents = deepDataAndEvents == null ? dataAndEvents : deepDataAndEvents;

    return this.map( function () {
        return jQuery.clone( this, dataAndEvents, deepDataAndEvents );
    });
},

Here's a jQuery example where the argument can be missing or any one of three different types which gives you four different overloads:

html: function( value ) {
    if ( value === undefined ) {
        return this[0] && this[0].nodeType === 1 ?
            this[0].innerHTML.replace(rinlinejQuery, "") :
            null;

    // See if we can take a shortcut and just use innerHTML
    } else if ( typeof value === "string" && !rnoInnerhtml.test( value ) &&
        (jQuery.support.leadingWhitespace || !rleadingWhitespace.test( value )) &&
        !wrapMap[ (rtagName.exec( value ) || ["", ""])[1].toLowerCase() ] ) {

        value = value.replace(rxhtmlTag, "<$1></$2>");

        try {
            for ( var i = 0, l = this.length; i < l; i++ ) {
                // Remove element nodes and prevent memory leaks
                if ( this[i].nodeType === 1 ) {
                    jQuery.cleanData( this[i].getElementsByTagName("*") );
                    this[i].innerHTML = value;
                }
            }

        // If using innerHTML throws an exception, use the fallback method
        } catch(e) {
            this.empty().append( value );
        }

    } else if ( jQuery.isFunction( value ) ) {
        this.each(function(i){
            var self = jQuery( this );

            self.html( value.call(this, i, self.html()) );
        });

    } else {
        this.empty().append( value );
    }

    return this;
},

Named Arguments

Other languages (like Python) allow one to pass named arguments as a means of passing only some arguments and making the arguments independent of the order they are passed in. Javascript does not directly support the feature of named arguments. A design pattern that is commonly used in its place is to pass a map of properties/values. This can be done by passing an object with properties and values or in ES6 and above, you could actually pass a Map object itself.

Here's a simple ES5 example:

jQuery's $.ajax() accepts a form of usage where you just pass it a single parameter which is a regular Javascript object with properties and values. Which properties you pass it determine which arguments/options are being passed to the ajax call. Some may be required, many are optional. Since they are properties on an object, there is no specific order. In fact, there are more than 30 different properties that can be passed on that object, only one (the url) is required.

Here's an example:

$.ajax({url: "http://www.example.com/somepath", data: myArgs, dataType: "json"}).then(function(result) {
    // process result here
});

Inside of the $.ajax() implementation, it can then just interrogate which properties were passed on the incoming object and use those as named arguments. This can be done either with for (prop in obj) or by getting all the properties into an array with Object.keys(obj) and then iterating that array.

This technique is used very commonly in Javascript when there are large numbers of arguments and/or many arguments are optional. Note: this puts an onus on the implementating function to make sure that a minimal valid set of arguments is present and to give the caller some debug feedback what is missing if insufficient arguments are passed (probably by throwing an exception with a helpful error message).

In an ES6 environment, it is possible to use destructuring to create default properties/values for the above passed object. This is discussed in more detail in this reference article.

Here's one example from that article:

function selectEntries({ start=0, end=-1, step=1 } = {}) {
    ···
};

This creates default properties and values for the start, end and step properties on an object passed to the selectEntries() function.

Default values for function arguments

In ES6, Javascript adds built-in language support for default values for arguments.

For example:

function multiply(a, b = 1) {
  return a*b;
}

multiply(5); // 5

Further description of the ways this can be used here on MDN.

Here is a nice extension I wrote...

extension Dictionary where Value: Any {
    public func mergeOnto(target: [Key: Value]?) -> [Key: Value] {
        guard let target = target else { return self }
        return self.merging(target) { current, _ in current }
    }
}

to use:

var dict1 = ["cat": 5, "dog": 6]
var dict2 = ["dog": 9, "rodent": 10]

dict1 = dict1.mergeOnto(target: dict2)

Then, dict1 will be modified to

["cat": 5, "dog": 6, "rodent": 10]

You have to use code similar to this:

echo "<div id='divwithform'>";

if(isset($_POST['submit']))  // if form was submitted (if you came here with form data)
{
    echo "Success";
}
else                // if form was not submitted (if you came here without form data)
{
    echo "<form> ... </form>";
} 

echo "</div>";

Code with if like this is typical for many pages, however this is very simplified.

Normally, you have to validate some data in first "if" (check if form fields were not empty etc).

Please visit www.thenewboston.org or phpacademy.org. There are very good PHP video tutorials, including forms.

Simple, clean solution for those who only target modern browsers:

function downloadTextFile(text, name) {
  const a = document.createElement('a');
  const type = name.split(".").pop();
  a.href = URL.createObjectURL( new Blob([text], { type:`text/${type === "txt" ? "plain" : type}` }) );
  a.download = name;
  a.click();
}

downloadTextFile(JSON.stringify(myObj), 'myObj.json');

I was looking for a inline editing solution and I found a plunker that seemed promising, but it didn't work for me out of the box. After some tinkering with the code I got it working. Kudos to the person who made the initial effort to code this piece.

The example is available here http://plnkr.co/edit/EsW7mV?p=preview

Here goes the code:

app.controller('MainCtrl', function($scope) {

  $scope.updateTodo = function(indx) {
    console.log(indx);
  };

  $scope.cancelEdit = function(value) {
    console.log('Canceled editing', value);
  };

  $scope.todos = [
    {id:123, title: 'Lord of the things'},
    {id:321, title: 'Hoovering heights'},
    {id:231, title: 'Watership brown'}
  ];
});

// On esc event
app.directive('onEsc', function() {
  return function(scope, elm, attr) {
    elm.bind('keydown', function(e) {
      if (e.keyCode === 27) {
        scope.$apply(attr.onEsc);
      }
    });
  };
});

// On enter event
app.directive('onEnter', function() {
  return function(scope, elm, attr) {
    elm.bind('keypress', function(e) {
      if (e.keyCode === 13) {
        scope.$apply(attr.onEnter);
      }
    });
  };
});

// Inline edit directive
app.directive('inlineEdit', function($timeout) {
  return {
    scope: {
      model: '=inlineEdit',
      handleSave: '&onSave',
      handleCancel: '&onCancel'
    },
    link: function(scope, elm, attr) {
      var previousValue;

      scope.edit = function() {
        scope.editMode = true;
        previousValue = scope.model;

        $timeout(function() {
          elm.find('input')[0].focus();
        }, 0, false);
      };
      scope.save = function() {
        scope.editMode = false;
        scope.handleSave({value: scope.model});
      };
      scope.cancel = function() {
        scope.editMode = false;
        scope.model = previousValue;
        scope.handleCancel({value: scope.model});
      };
    },
    templateUrl: 'inline-edit.html'
  };
});

Directive template:

<div>
  <input type="text" on-enter="save()" on-esc="cancel()" ng-model="model" ng-show="editMode">
  <button ng-click="cancel()" ng-show="editMode">cancel</button>
  <button ng-click="save()" ng-show="editMode">save</button>
  <span ng-mouseenter="showEdit = true" ng-mouseleave="showEdit = false">
    <span ng-hide="editMode" ng-click="edit()">{{model}}</span>
    <a ng-show="showEdit" ng-click="edit()">edit</a>
  </span>
</div>

To use it just add water:

<div ng-repeat="todo in todos" 
     inline-edit="todo.title" 
     on-save="updateTodo($index)" 
     on-cancel="cancelEdit(todo.title)"></div>

UPDATE:

Another option is to use the readymade Xeditable for AngularJS:

Supplemental answer

Given an OnTouchListener

private View.OnTouchListener handleTouch = new View.OnTouchListener() {

    @Override
    public boolean onTouch(View v, MotionEvent event) {

        int x = (int) event.getX();
        int y = (int) event.getY();

        switch (event.getAction()) {
            case MotionEvent.ACTION_DOWN:
                Log.i("TAG", "touched down");
                break;
            case MotionEvent.ACTION_MOVE:
                Log.i("TAG", "moving: (" + x + ", " + y + ")");
                break;
            case MotionEvent.ACTION_UP:
                Log.i("TAG", "touched up");
                break;
        }

        return true;
    }
};

set on some view:

myView.setOnTouchListener(handleTouch);

This gives you the touch event coordinates relative to the view that has the touch listener assigned to it. The top left corner of the view is (0, 0). If you move your finger above the view, then y will be negative. If you move your finger left of the view, then x will be negative.

int x = (int)event.getX();
int y = (int)event.getY();

If you want the coordinates relative to the top left corner of the device screen, then use the raw values.

int x = (int)event.getRawX();
int y = (int)event.getRawY();

The object-fit CSS property sets how the content of a replaced element, such as an img or video, should be resized to fit its container.

Magically, object fit also works on a canvas element. No JavaScript needed, and the canvas doesn't stretch, automatically fills to proportion.

With this example (I just closed the open tags):

Here is a monkeyrunner script that sends touch and drags to an application. I have been using this to test that my application can handle rapid repetitive swipe gestures.

# This is a monkeyrunner jython script that opens a connection to an Android

#
# See http://developer.android.com/guide/developing/tools/monkeyrunner_concepts.html

# Imports the monkeyrunner modules used by this program
from com.android.monkeyrunner import MonkeyRunner, MonkeyDevice

# Connects to the current device
device = MonkeyRunner.waitForConnection()

# A swipe left from (x1, y) to (x2, y) in 2 steps
y = 400
x1 = 100
x2 = 300
start = (x1, y)
end = (x2, y)
duration = 0.2
steps = 2
pause = 0.2

for i in range(1, 250):
    # Every so often inject a touch to spice things up!
    if i % 9 == 0:
        device.touch(x2, y, 'DOWN_AND_UP')
        MonkeyRunner.sleep(pause)
    # Swipe right
    device.drag(start, end, duration, steps)

    # Swipe left

Technically, the Integrity attribute helps with just that - it enables the proper verification of the data source. That is, it merely allows the browser to verify the numbers in the right source file with the amounts requested by the source file located on the CDN server.

Going a bit deeper, in case of the established encrypted hash value of this source and its checked compliance with a predefined value in the browser - the code executes, and the user request is successfully processed.

Crossorigin attribute helps developers optimize the rates of CDN performance, at the same time, protecting the website code from malicious scripts.

In particular, Crossorigin downloads the program code of the site in anonymous mode, without downloading cookies or performing the authentication procedure. This way, it prevents the leak of user data when you first load the site on a specific CDN server, which network fraudsters can easily replace addresses.

There are two ways to do this:

1. in stead of using user._id use user.id and it will return a string for you
2. If you really want to go the long way around you can use user._id.toString()

• Click on the orange button ("choose files")
• Browse to the Swagger doc (swagger.yaml)
• After selecting the file, a new collection gets created in POSTMAN. It will contain folders based on your endpoints.

You can also get some sample swagger files online to verify this(if you have errors in your swagger doc).

If you need an algorithm, try this: Convert the color from RGB space to HSV space (Hue, Saturation, Value). If your UI framework can't do it, check this article: http://en.wikipedia.org/wiki/HSL_and_HSV#Conversion_from_RGB_to_HSL_or_HSV

Hue is in [0,360). To find the "opposite" color (think colorwheel), just add 180 degrees:

h = (h + 180) % 360;

For saturation and value, invert them:

l = 1.0 - l;
v = 1.0 - v;

Convert back to RGB. This should always give you a high contrast even though most combinations will look ugly.

If you want to avoid the "ugly" part, build a table with several "good" combinations, find the one with the least difference

def q(x):
    return x*x
def diff(col1, col2):
    return math.sqrt(q(col1.r-col2.r) + q(col1.g-col2.g) + q(col1.b-col2.b))

and use that.

First thing's first, if your dates are in varchar format change that, store dates as dates it will save you a lot of headaches and it is something that is best done sooner rather than later. The problem will only get worse.

Secondly, once you have a date DO NOT convert the date to a varchar! Keep it in date format and use formatting on the application side to get the required date format.

There are various methods to do this depending on your DBMS:

SQL-Server 2008 and later:

SELECT  CAST(CURRENT_TIMESTAMP AS DATE)

SQL-Server 2005 and Earlier

SELECT  DATEADD(DAY, DATEDIFF(DAY, 0, CURRENT_TIMESTAMP), 0)

SQLite

SELECT  DATE(NOW())

Oracle

SELECT  TRUNC(CURRENT_TIMESTAMP)

Postgresql

SELECT  CURRENT_TIMESTAMP::DATE

If you need to use culture specific formatting in your report you can either explicitly state the format of the receiving text box (e.g. dd/MM/yyyy), or you can set the language so that it shows the relevant date format for that language.

Either way this is much better handled outside of SQL as converting to varchar within SQL will impact any sorting you may do in your report.

If you cannot/will not change the datatype to DATETIME, then still convert it to a date within SQL (e.g. CONVERT(DATETIME, yourField)) before sending to report services and handle it as described above.

INSERT INTO `dbMyDataBase`.`tblMyTable` 
(
    `IdAutoincrement`, 
    `Column2`, 
    `Column3`, 
    `Column4` 
) 

SELECT 
    NULL,  
    `Column2`, 
    `Column3`, 
    'CustomValue' AS Column4 
FROM `dbMyDataBase`.`tblMyTable` 
WHERE `tblMyTable`.`Column2` = 'UniqueValueOfTheKey' 
; 
/* mySQL 5.6 */

Update: Yes, I understand that this answer does not explain the difference between arm64 and armhf. There is a great answer that does explain that on this page. This answer was intended to help set the asker on the right path, as they clearly had a misunderstanding about the capabilities of the Raspberry Pi at the time of asking.

Where are you seeing that the architecture is armhf? On my Raspberry Pi 3, I get:

$ uname -a
armv7l

Anyway, armv7 indicates that the system architecture is 32-bit. The first ARM architecture offering 64-bit support is armv8. See this table for reference.

You are correct that the CPU in the Raspberry Pi 3 is 64-bit, but the Raspbian OS has not yet been updated for a 64-bit device. 32-bit software can run on a 64-bit system (but not vice versa). This is why you're not seeing the architecture reported as 64-bit.

You can follow the GitHub issue for 64-bit support here, if you're interested.

For anyone looking for a full solution, I got this working with the following code based on maximdim's answer:

import javax.mail.*
import javax.mail.internet.*

private class SMTPAuthenticator extends Authenticator
{
    public PasswordAuthentication getPasswordAuthentication()
    {
        return new PasswordAuthentication('[email protected]', 'test1234');
    }
}

def  d_email = "[email protected]",
        d_uname = "email",
        d_password = "password",
        d_host = "smtp.gmail.com",
        d_port  = "465", //465,587
        m_to = "[email protected]",
        m_subject = "Testing",
        m_text = "Hey, this is the testing email."

def props = new Properties()
props.put("mail.smtp.user", d_email)
props.put("mail.smtp.host", d_host)
props.put("mail.smtp.port", d_port)
props.put("mail.smtp.starttls.enable","true")
props.put("mail.smtp.debug", "true");
props.put("mail.smtp.auth", "true")
props.put("mail.smtp.socketFactory.port", d_port)
props.put("mail.smtp.socketFactory.class", "javax.net.ssl.SSLSocketFactory")
props.put("mail.smtp.socketFactory.fallback", "false")

def auth = new SMTPAuthenticator()
def session = Session.getInstance(props, auth)
session.setDebug(true);

def msg = new MimeMessage(session)
msg.setText(m_text)
msg.setSubject(m_subject)
msg.setFrom(new InternetAddress(d_email))
msg.addRecipient(Message.RecipientType.TO, new InternetAddress(m_to))

Transport transport = session.getTransport("smtps");
transport.connect(d_host, 465, d_uname, d_password);
transport.sendMessage(msg, msg.getAllRecipients());
transport.close();

If you know the settings in advance you can define it in a single statement:

var defaultsettings = {
                        ajaxsettings : { "ak1" : "v1", "ak2" : "v2", etc. },
                        uisettings : { "ui1" : "v1", "ui22" : "v2", etc }
                      };

If you don't know the values in advance you can just define the top level object and then add properties:

var defaultsettings = { };
defaultsettings["ajaxsettings"] = {};
defaultsettings["ajaxsettings"]["somekey"] = "some value";

Or half-way between the two, define the top level with nested empty objects as properties and then add properties to those nested objects:

var defaultsettings = {
                        ajaxsettings : {  },
                        uisettings : {  }
                      };

defaultsettings["ajaxsettings"]["somekey"] = "some value";
defaultsettings["uisettings"]["somekey"] = "some value";

You can nest as deep as you like using the above techniques, and anywhere that you have a string literal in the square brackets you can use a variable:

var keyname = "ajaxsettings";
var defaultsettings = {};
defaultsettings[keyname] = {};
defaultsettings[keyname]["some key"] = "some value";

Note that you can not use variables for key names in the { } literal syntax.

I have traversed hundred of pages, googled a lot but i have not found any exact solution. Finally this worked for me. Irrespective where you are in either controller or model. This code worked for me every where. Just use this

//Before executing your query
$db = Zend_Db_Table_Abstract::getDefaultAdapter();
$db->getProfiler()->setEnabled(true);
$profiler = $db->getProfiler();

// Execute your any of database query here like select, update, insert
//The code below must be after query execution
$query  = $profiler->getLastQueryProfile();
$params = $query->getQueryParams();
$querystr  = $query->getQuery();

foreach ($params as $par) {
    $querystr = preg_replace('/\\?/', "'" . $par . "'", $querystr, 1);
}
echo $querystr;

Finally this thing worked for me.
