@ImportanceOfBeingErnest 's answer is good if you only want to change the linewidth inside the legend box. But I think it is a bit more complex since you have to copy the handles before changing legend linewidth. Besides, it can not change the legend label fontsize. The following two methods can not only change the linewidth but also the legend label text font size in a more concise way.

Method 1

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the individual lines inside legend and set line width
for line in leg.get_lines():
    line.set_linewidth(4)
# get label texts inside legend and set font size
for text in leg.get_texts():
    text.set_fontsize('x-large')

plt.savefig('leg_example')
plt.show()

Method 2

import numpy as np
import matplotlib.pyplot as plt

# make some data
x = np.linspace(0, 2*np.pi)

y1 = np.sin(x)
y2 = np.cos(x)

# plot sin(x) and cos(x)
fig = plt.figure()
ax  = fig.add_subplot(111)
ax.plot(x, y1, c='b', label='y1')
ax.plot(x, y2, c='r', label='y2')

leg = plt.legend()
# get the lines and texts inside legend box
leg_lines = leg.get_lines()
leg_texts = leg.get_texts()
# bulk-set the properties of all lines and texts
plt.setp(leg_lines, linewidth=4)
plt.setp(leg_texts, fontsize='x-large')
plt.savefig('leg_example')
plt.show()

The above two methods produce the same output image:

tk.mainloop() blocks. It means that execution of your Python commands halts there. You can see that by writing:

while 1:
    ball.draw()
    tk.mainloop()
    print("hello")   #NEW CODE
    time.sleep(0.01)

You will never see the output from the print statement. Because there is no loop, the ball doesn't move.

On the other hand, the methods update_idletasks() and update() here:

while True:
    ball.draw()
    tk.update_idletasks()
    tk.update()

...do not block; after those methods finish, execution will continue, so the while loop will execute over and over, which makes the ball move.

An infinite loop containing the method calls update_idletasks() and update() can act as a substitute for calling tk.mainloop(). Note that the whole while loop can be said to block just like tk.mainloop() because nothing after the while loop will execute.

However, tk.mainloop() is not a substitute for just the lines:

tk.update_idletasks()
tk.update()

Rather, tk.mainloop() is a substitute for the whole while loop:

while True:
    tk.update_idletasks()
    tk.update()

Response to comment:

Here is what the tcl docs say:

Update idletasks

This subcommand of update flushes all currently-scheduled idle events from Tcl's event queue. Idle events are used to postpone processing until “there is nothing else to do”, with the typical use case for them being Tk's redrawing and geometry recalculations. By postponing these until Tk is idle, expensive redraw operations are not done until everything from a cluster of events (e.g., button release, change of current window, etc.) are processed at the script level. This makes Tk seem much faster, but if you're in the middle of doing some long running processing, it can also mean that no idle events are processed for a long time. By calling update idletasks, redraws due to internal changes of state are processed immediately. (Redraws due to system events, e.g., being deiconified by the user, need a full update to be processed.)

APN As described in Update considered harmful, use of update to handle redraws not handled by update idletasks has many issues. Joe English in a comp.lang.tcl posting describes an alternative:

So update_idletasks() causes some subset of events to be processed that update() causes to be processed.

From the update docs:

update ?idletasks?

The update command is used to bring the application “up to date” by entering the Tcl event loop repeatedly until all pending events (including idle callbacks) have been processed.

If the idletasks keyword is specified as an argument to the command, then no new events or errors are processed; only idle callbacks are invoked. This causes operations that are normally deferred, such as display updates and window layout calculations, to be performed immediately.

KBK (12 February 2000) -- My personal opinion is that the [update] command is not one of the best practices, and a programmer is well advised to avoid it. I have seldom if ever seen a use of [update] that could not be more effectively programmed by another means, generally appropriate use of event callbacks. By the way, this caution applies to all the Tcl commands (vwait and tkwait are the other common culprits) that enter the event loop recursively, with the exception of using a single [vwait] at global level to launch the event loop inside a shell that doesn't launch it automatically.

The commonest purposes for which I've seen [update] recommended are:

1. Keeping the GUI alive while some long-running calculation is executing. See Countdown program for an alternative. 2) Waiting for a window to be configured before doing things like geometry management on it. The alternative is to bind on events such as that notify the process of a window's geometry. See Centering a window for an alternative.

What's wrong with update? There are several answers. First, it tends to complicate the code of the surrounding GUI. If you work the exercises in the Countdown program, you'll get a feel for how much easier it can be when each event is processed on its own callback. Second, it's a source of insidious bugs. The general problem is that executing [update] has nearly unconstrained side effects; on return from [update], a script can easily discover that the rug has been pulled out from under it. There's further discussion of this phenomenon over at Update considered harmful.

.....

Is there any chance I can make my program work without the while loop?

Yes, but things get a little tricky. You might think something like the following would work:

class Ball:
    def __init__(self, canvas, color):
        self.canvas = canvas
        self.id = canvas.create_oval(10, 10, 25, 25, fill=color)
        self.canvas.move(self.id, 245, 100)

    def draw(self):
        while True:
           self.canvas.move(self.id, 0, -1)

ball = Ball(canvas, "red")
ball.draw()
tk.mainloop()

The problem is that ball.draw() will cause execution to enter an infinite loop in the draw() method, so tk.mainloop() will never execute, and your widgets will never display. In gui programming, infinite loops have to be avoided at all costs in order to keep the widgets responsive to user input, e.g. mouse clicks.

So, the question is: how do you execute something over and over again without actually creating an infinite loop? Tkinter has an answer for that problem: a widget's after() method:

from Tkinter import *
import random
import time

tk = Tk()
tk.title = "Game"
tk.resizable(0,0)
tk.wm_attributes("-topmost", 1)

canvas = Canvas(tk, width=500, height=400, bd=0, highlightthickness=0)
canvas.pack()

class Ball:
    def __init__(self, canvas, color):
        self.canvas = canvas
        self.id = canvas.create_oval(10, 10, 25, 25, fill=color)
        self.canvas.move(self.id, 245, 100)

    def draw(self):
        self.canvas.move(self.id, 0, -1)
        self.canvas.after(1, self.draw)  #(time_delay, method_to_execute)


       

ball = Ball(canvas, "red")
ball.draw()  #Changed per Bryan Oakley's comment
tk.mainloop()

The after() method doesn't block (it actually creates another thread of execution), so execution continues on in your python program after after() is called, which means tk.mainloop() executes next, so your widgets get configured and displayed. The after() method also allows your widgets to remain responsive to other user input. Try running the following program, and then click your mouse on different spots on the canvas:

from Tkinter import *
import random
import time

root = Tk()
root.title = "Game"
root.resizable(0,0)
root.wm_attributes("-topmost", 1)

canvas = Canvas(root, width=500, height=400, bd=0, highlightthickness=0)
canvas.pack()

class Ball:
    def __init__(self, canvas, color):
        self.canvas = canvas
        self.id = canvas.create_oval(10, 10, 25, 25, fill=color)
        self.canvas.move(self.id, 245, 100)

        self.canvas.bind("<Button-1>", self.canvas_onclick)
        self.text_id = self.canvas.create_text(300, 200, anchor='se')
        self.canvas.itemconfig(self.text_id, text='hello')

    def canvas_onclick(self, event):
        self.canvas.itemconfig(
            self.text_id, 
            text="You clicked at ({}, {})".format(event.x, event.y)
        )

    def draw(self):
        self.canvas.move(self.id, 0, -1)
        self.canvas.after(50, self.draw)


       

ball = Ball(canvas, "red")
ball.draw()  #Changed per Bryan Oakley's comment.
root.mainloop()

I want to correct little bit the above code

    public class MainActivity extends ActionBarActivity {
        @Override
        protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        Toolbar mToolbar = (Toolbar) findViewById(R.id.toolbar);
        DrawerLayout mDrawerLayout = (DrawerLayout) findViewById(R.id.drawer_layout);
        ActionBarDrawerToggle mDrawerToggle = new ActionBarDrawerToggle(
            this,  mDrawerLayout, mToolbar,
            R.string.navigation_drawer_open, R.string.navigation_drawer_close
        );
        mDrawerLayout.setDrawerListener(mDrawerToggle);

        getSupportActionBar().setDisplayHomeAsUpEnabled(true);
        getSupportActionBar().setHomeButtonEnabled(true);
    }

and all the other things will remain same...

For those who are having problem Drawerlayout overlaying toolbar

add android:layout_marginTop="?attr/actionBarSize" to root layout of drawer content

I realized a Open Source library on GitHub CircularProgressBar that does exactly what you want the simplest way possible:

USAGE

To make a circular ProgressBar add CircularProgressBar in your layout XML and add CircularProgressBar library in your projector or you can also grab it via Gradle:

compile 'com.mikhaellopez:circularprogressbar:1.0.0'

XML

<com.mikhaellopez.circularprogressbar.CircularProgressBar
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    app:background_progressbar_color="#FFCDD2"
    app:background_progressbar_width="5dp"
    app:progressbar_color="#F44336"
    app:progressbar_width="10dp" />

You must use the following properties in your XML to change your CircularProgressBar.

Properties:

• app:progress (integer) >> default 0
• app:progressbar_color (color) >> default BLACK
• app:background_progressbar_color (color) >> default GRAY
• app:progressbar_width (dimension) >> default 7dp
• app:background_progressbar_width (dimension) >> default 3dp

JAVA

CircularProgressBar circularProgressBar = (CircularProgressBar)findViewById(R.id.yourCircularProgressbar);
circularProgressBar.setColor(ContextCompat.getColor(this, R.color.progressBarColor));
circularProgressBar.setBackgroundColor(ContextCompat.getColor(this, R.color.backgroundProgressBarColor));
circularProgressBar.setProgressBarWidth(getResources().getDimension(R.dimen.progressBarWidth));
circularProgressBar.setBackgroundProgressBarWidth(getResources().getDimension(R.dimen.backgroundProgressBarWidth));
int animationDuration = 2500; // 2500ms = 2,5s
circularProgressBar.setProgressWithAnimation(65, animationDuration); // Default duration = 1500ms

Fork or Download this library here >> https://github.com/lopspower/CircularProgressBar

Use:

<Button Height="100" Width="100">
  <StackPanel>
    <Image Source="img.jpg" />
    <TextBlock Text="Blabla" />
  </StackPanel>
</Button>

It should work. But remember that you must have an image added to the resource on your project!

I will do something simple like :

.thickness-underline {
    display: inline-block;
    text-decoration: none;
    border-bottom: 1px solid black;
    margin-bottom: -1px;
}

• You can use line-height or padding-bottom to set possition between them
• You can use display: inline in some case

Demo : http://jsfiddle.net/5580pqe8/

Take a look at calc() specification. Here is an example of usage:

border-right:1px solid;
border-left:1px solid;
width:calc(100% - 2px);

For Swift 3 and 4, if you're willing to use IBInspectables, there's this:

@IBDesignable extension UIView {
    @IBInspectable var borderColor:UIColor? {
        set {
            layer.borderColor = newValue!.cgColor
        }
        get {
            if let color = layer.borderColor {
                return UIColor(cgColor: color)
            }
            else {
                return nil
            }
        }
    }
    @IBInspectable var borderWidth:CGFloat {
        set {
            layer.borderWidth = newValue
        }
        get {
            return layer.borderWidth
        }
    }
    @IBInspectable var cornerRadius:CGFloat {
        set {
            layer.cornerRadius = newValue
            clipsToBounds = newValue > 0
        }
        get {
            return layer.cornerRadius
        }
    }
}

Check this example .. everything has been done easily http://jsfiddle.net/GHzfD/

Instead of using a UIView, as @ImreKelényi suggests, you can use a CALayer:

// Add a bottomBorder.
CALayer *bottomBorder = [CALayer layer];

bottomBorder.frame = CGRectMake(0.0f, 43.0f, toScrollView.frame.size.width, 1.0f);

bottomBorder.backgroundColor = [UIColor colorWithWhite:0.8f 
                                                 alpha:1.0f].CGColor;

[toScrollView.layer addSublayer:bottomBorder];

Here are some vendors you might me looking for

::-webkit-input-placeholder {color: tomato}
::-moz-placeholder          {color: tomato;} /* Firefox 19+ */
:-moz-placeholder           {color: tomato;} /* Firefox 18- */
:-ms-input-placeholder      {color: tomato;}

You can also style different states, such as focus

:focus::-webkit-input-placeholder {color: transparent}
:focus::-moz-placeholder          {color: transparent}
:focus:-moz-placeholder           {color: transparent}
:focus:-ms-input-placeholder      {color: transparent}

You can also do certain transitions on it, like

::-VENDOR-input-placeholder       {text-indent: 0px;   transition: text-indent 0.3s ease;}
:focus::-VENDOR-input-placeholder  {text-indent: 500px; transition: text-indent 0.3s ease;}

I was looking for shortest way to draw an 1px line, as whole load of separated CSS is not the fastest or shortest solution.

Up to HTML5, the WAS a shorter way for 1px hr: <hr noshade> but.. The noshade attribute of <hr> is not supported in HTML5. Use CSS instead. (nor other attibutes used before, as size, width, align)...

Now, this one is quite tricky, but works well if most simple 1px hr needed:

Variation 1, BLACK hr: (best solution for black)

<hr style="border-bottom: 0px">

Output: FF, Opera - black / Safari - dark gray

Variation 2, GRAY hr (shortest!):

<hr style="border-top: 0px">

Output: Opera - dark gray / FF - gray / Safari - light gray

<hr style="border: none; border-bottom: 1px solid red;">

Output: Opera / FF / Safari : 1px red.

Circle Time! :) Easy way of making a circle with a hollow center : use border-radius, give the element a border and no background so you can see through it :

div {_x000D_
    display: inline-block;_x000D_
    margin-left: 5px;_x000D_
    height: 100px;_x000D_
    border-radius: 100%;_x000D_
    width:100px;_x000D_
    border:solid black 2px;_x000D_
}_x000D_
_x000D_
body{_x000D_
    background:url('http://lorempixel.com/output/people-q-c-640-480-1.jpg');_x000D_
    background-size:cover;_x000D_
}

<div></div>

If you didn't want to edit the layer of a UIView, you could always embed the view within another view. The parent view would have its background color set to the border color. It would also be slightly larger, depending upon how wide you want the border to be.

Of course, this only works if your view isn't transparent and you only want a single border color. The OP wanted the border in the view itself, but this may be a viable alternative.

Your style should look like this:

<style parent="@android:style/Widget.ProgressBar" name="customProgressBar">
    <item name="android:indeterminateDrawable">@anim/mp3</item>
</style>

a demo:

You set DockPanel.Dock="Top" to the StackPanel, but the StackPanel is not a child of the DockPanel... the Border is. Your docking property is being ignored.

If you move DockPanel.Dock="Top" to the Border instead, both of your problems will be fixed :)

To get a scrollbar for an ItemsControl, you can host it in a ScrollViewer like this:

<ScrollViewer VerticalScrollBarVisibility="Auto">
  <ItemsControl>
    <uc:UcSpeler />
    <uc:UcSpeler />
    <uc:UcSpeler />
    <uc:UcSpeler />
    <uc:UcSpeler />
  </ItemsControl>
</ScrollViewer>

Try this style instead, it modifies the template itself. In there you can change everything you need to transparent:

<Style TargetType="{x:Type TabItem}">
  <Setter Property="Template">
    <Setter.Value>
      <ControlTemplate TargetType="{x:Type TabItem}">
        <Grid>
          <Border Name="Border" Margin="0,0,0,0" Background="Transparent"
                  BorderBrush="Black" BorderThickness="1,1,1,1" CornerRadius="5">
            <ContentPresenter x:Name="ContentSite" VerticalAlignment="Center"
                              HorizontalAlignment="Center"
                              ContentSource="Header" Margin="12,2,12,2"
                              RecognizesAccessKey="True">
              <ContentPresenter.LayoutTransform>
            <RotateTransform Angle="270" />
          </ContentPresenter.LayoutTransform>
        </ContentPresenter>
          </Border>
        </Grid>
        <ControlTemplate.Triggers>
          <Trigger Property="IsSelected" Value="True">
            <Setter Property="Panel.ZIndex" Value="100" />
            <Setter TargetName="Border" Property="Background" Value="Red" />
            <Setter TargetName="Border" Property="BorderThickness" Value="1,1,1,0" />
          </Trigger>
          <Trigger Property="IsEnabled" Value="False">
            <Setter TargetName="Border" Property="Background" Value="DarkRed" />
            <Setter TargetName="Border" Property="BorderBrush" Value="Black" />
            <Setter Property="Foreground" Value="DarkGray" />
          </Trigger>
        </ControlTemplate.Triggers>
      </ControlTemplate>
    </Setter.Value>
  </Setter>
</Style>

Why don't you set both Background & BorderBrush by same brush

 <Style TargetType="{x:Type Button}" >
        <Setter Property="Background" Value="{StaticResource marginBackGround}"></Setter>
        <Setter Property="BorderBrush" Value="{StaticResource marginBackGround}"></Setter>            
 </Style>

<LinearGradientBrush  x:Key="marginBackGround" EndPoint=".5,1" StartPoint="0.5,0">
    <GradientStop Color="#EE82EE" Offset="0"/>
    <GradientStop Color="#7B30B6" Offset="0.5"/>
    <GradientStop Color="#510088" Offset="0.5"/>
    <GradientStop Color="#76209B" Offset="0.9"/>
    <GradientStop Color="#C750B9" Offset="1"/>
</LinearGradientBrush>

pattern = '\[P\].+?\[\/P\]'

For moving a virtual machine you need not clone the VM, just copy the VM files (after powering the VM off) to external HDD and register the same on destination host.

Try this

    $(function() {

$('#clickMe').click(function(event) {
    var mytext = $('#myText').val();


    $('<div id="dialog">'+mytext+'</div>').appendTo('body');        
    event.preventDefault();

        $("#dialog").dialog({                   
            width: 600,
            modal: true,
            close: function(event, ui) {
                $("#dialog").remove();
                }
            });
    }); //close click
});

And in HTML

<h3 id="clickMe">Open dialog</h3>
<textarea cols="0" rows="0" id="myText" style="display:none">Some hidden text display none</textarea>

it depends what sort of t-test you want to do (one sided or two sided dependent or independent) but it should be as simple as:

from scipy.stats import ttest_ind

cat1 = my_data[my_data['Category']=='cat1']
cat2 = my_data[my_data['Category']=='cat2']

ttest_ind(cat1['values'], cat2['values'])
>>> (1.4927289925706944, 0.16970867501294376)

it returns a tuple with the t-statistic & the p-value

see here for other t-tests http://docs.scipy.org/doc/scipy/reference/stats.html

The default fonts are different across Windows, Mac, and Linux. As of VSCode 1.15.1, the default font settings can be found in the source code:

const DEFAULT_WINDOWS_FONT_FAMILY = 'Consolas, \'Courier New\', monospace';
const DEFAULT_MAC_FONT_FAMILY = 'Menlo, Monaco, \'Courier New\', monospace';
const DEFAULT_LINUX_FONT_FAMILY = '\'Droid Sans Mono\', \'Courier New\', monospace, \'Droid Sans Fallback\'';

Add your icon as a Resource (Project > yourprojectname Properties > Resources > Pick "Icons from dropdown > Add Resource (or choose Add Existing File from dropdown if you already have the .ico)

Then:

this.Icon = Properties.Resources.youriconname;

I found that this works really well in Chrome.

Right click on the element that you'd like to inspect, then click Force Element State > Hover. Screenshot attached.

TreeSize professional has what you want. but it focus on the sizes of folders and files.

It is bad practice to throw Exception, as that requires anyone who calls your constructor to catch Exception which is a bad practice.

It is a good idea to have a constructor (or any method) throw an exception, generally speaking IllegalArgumentException, which is unchecked, and thus the compiler doesn't force you to catch it.

You should throw checked exceptions (things that extend from Exception, but not RuntimeException) if you want the caller to catch it.

Use the CSS Flexbox flex-grow property to achieve this.

.main {
  display: flex;
}
.col-1, .col-3 {
  width: 100px;
}
.col-2 {
  flex-grow: 1;
}

<div class="main">
  <div class="col-1" style="background: #fc9;">Left column</div>
  <div class="col-2" style="background: #eee;">Middle column</div>
  <div class="col-3" style="background: #fc9;">Right column</div>
</div>

You can use inWaiting() to get the amount of bytes available at the input queue.

Then you can use read() to read the bytes, something like that:

While True:
    bytesToRead = ser.inWaiting()
    ser.read(bytesToRead)

Why not to use readline() at this case from Docs:

Read a line which is terminated with end-of-line (eol) character (\n by default) or until timeout.

You are waiting for the timeout at each reading since it waits for eol. the serial input Q remains the same it just a lot of time to get to the "end" of the buffer, To understand it better: you are writing to the input Q like a race car, and reading like an old car :)

Use round()

$float_val = 4.5;

echo round($float_val);

You can also set param for precision and rounding mode, for more info

Update (According to your updated question):

$float_val = 1.0000124668092E+14;
printf('%.0f', $float_val / 1E+14); //Output Rounds Of To 1000012466809201

Here's my super cool version BECAUSE IT HAS A PROGRESS BAR :-)

Which is a completely useless feature, I know, but it still looks cool \m/ \m/

$webclient = New-Object System.Net.WebClient
Register-ObjectEvent -InputObject $webclient -EventName "UploadProgressChanged" -Action { Write-Progress -Activity "Upload progress..." -Status "Uploading" -PercentComplete $EventArgs.ProgressPercentage } > $null

$File = "filename.zip"
$ftp = "ftp://user:password@server/filename.zip"
$uri = New-Object System.Uri($ftp)
try{
    $webclient.UploadFileAsync($uri, $File)
}
catch  [Net.WebException]
{
    Write-Host $_.Exception.ToString() -foregroundcolor red
}
while ($webclient.IsBusy) { continue }

PS. Helps a lot, when I'm wondering "did it stop working, or is it just my slow ASDL connection?"

Other answers here work fine, but AES is a more secure and up-to-date encryption algorithm. This is a class that I obtained a few years ago to perform AES encryption that I have modified over time to be more friendly for web applications (e,g. I've built Encrypt/Decrypt methods that work with URL-friendly string). It also has the methods that work with byte arrays.

NOTE: you should use different values in the Key (32 bytes) and Vector (16 bytes) arrays! You wouldn't want someone to figure out your keys by just assuming that you used this code as-is! All you have to do is change some of the numbers (must be <= 255) in the Key and Vector arrays (I left one invalid value in the Vector array to make sure you do this...). You can use https://www.random.org/bytes/ to generate a new set easily:

• generate Key
• generate Vector

Using it is easy: just instantiate the class and then call (usually) EncryptToString(string StringToEncrypt) and DecryptString(string StringToDecrypt) as methods. It couldn't be any easier (or more secure) once you have this class in place.

Javascript events deal with User Interaction, if your code is organised enough you should be able to call the initialising function in the same place where the visibility changes (i.e. you shouldn't change myElement.style.display on many places, instead, call a function/method that does this and anything else you might want).

While they are both rooted in C, they are two completely different languages.

A major difference is that Objective-C is focused on runtime-decisions for dispatching and heavily depends on its runtime library to handle inheritance and polymorphism, while in C++ the focus usually lies on static, compile time, decisions.

Regarding libraries, you can use plain C libraries in both languages - but their native libraries are completely different.

Of interest though is that you can mix both languages (with some limitations). The result is called Objective-C++.

You could also try jARVEST.

It is based on a JRuby DSL over a pure-Java engine to spider-scrape-transform web sites.

Example:

Find all links inside a web page (wget and xpath are constructs of the jARVEST's language):

wget | xpath('//a/@href')

Inside a Java program:

Jarvest jarvest = new Jarvest();
  String[] results = jarvest.exec(
    "wget | xpath('//a/@href')", //robot! 
    "http://www.google.com" //inputs
  );
  for (String s : results){
    System.out.println(s);
  }

Am a few years late in answering this question. With the state of the art pushed to its limits by CNNs in the last 5 years I wouldn't use OpenCV to do this task now! (I know you specifically wanted OpenCv features in the question) I feel object detection algorithms such as Faster-RCNNs, YOLO, SSD etc would ace this problem with a significant margin compared to OpenCV features. If I were to tackle this problem now (after 6 years !!) I would definitely use Faster-RCNN.

Spring Boot do a lot of automatically things to us but when we use the annotation @SpringBootTest we think that everything will be automatically solved by Spring boot.

There are a lot of documentation, but the minimal is to choose one engine (@RunWith(SpringRunner.class)) and indicate the class that will be used create the context to load the configuration (resources/applicationl.properties).

In a simple way you need the engine and the context:

@RunWith(SpringRunner.class)
@SpringBootTest(classes = MyClassTest .class)
public class MyClassTest {

    @Value("${my.property}")
    private String myProperty;

    @Test
    public void checkMyProperty(){
        Assert.assertNotNull(my.property);
    }
}

Of course, if you look the Spring Boot documentation you will find thousands os ways to do that.

You can achieve your result in two steps. First, create a list of unique entries using Advanced Filter... from the pull down Filter menu. To do so, you have to add a name of the column to be sorted out. It is necessary, otherwise Excel will treat first row as a name rather than an entry. Highlight column that you want to filter (A in the example below), click the filter icon and chose 'Advanced Filter...'. That will bring up a window where you can select an option to "Copy to another location". Choose that one, as you will need your original list to do counts (in my example I will choose C:C). Also, select "Unique record only". That will give you a list of unique entries. Then you can count their frequencies using =COUNTIF() command. See screedshots for details.

Hope this helps!

This has worked for me in both SQL Server 2005 and 2008:

SELECT * from TABLE
WHERE FIELDNAME > {ts '2013-02-01 15:00:00.001'}
  AND FIELDNAME < {ts '2013-08-05 00:00:00.000'}

I could not get mongoexport to do this for me. I found that,to get an exhaustive list of all the fields, you need to loop through the entire collection once. Use this to generate the headers. Then loop through the collection again to populate these headers for each document.

I've written a script to do just this. Converting MongoDB docs to csv irrespective of schema differences between individual documents.

to install uuid

npm install --save uuid

uuid is updated and the old import

const uuid= require('uuid/v4');

is not working and we should now use this import

const {v4:uuid} = require('uuid');

and for using it use as a funciton like this

const  createdPlace = {
    id: uuid(),
    title,
    description,
    location:coordinates,
    address,
    creator
  };

Server is trying to read data from the request, but its taking longer than the timeout value for the data to arrive from the client. Timeout here would typically be tomcat connector -> connectionTimeout attribute.

Correct.

Client has a read timeout set, and server is taking longer than that to respond.

No. That would cause a timeout at the client.

One of the threads i went through, said this can happen with high concurrency and if the keepalive is enabled.

That is obviously guesswork, and completely incorrect. It happens if and only if no data arrives within the timeout. Period. Load and keepalive and concurrency have nothing to do with it whatsoever.

It just means the client isn't sending. You don't need to worry about it. Browser clients come and go in all sorts of strange ways.

For fadeIn and fadeOut, only add this after super.onCreate(savedInstanceState) in your new Activity class. You don't need to create something else (No XML, no anim folder, no extra function).

I encountered the same problem when I built an application on a Windows 7 box that had previously been maintained on an XP machine.

The program ran fine when built for Debug, but failed with this error when built for Release. I found the answer on the project's Properties page. Go to the "Build" tab and try changing the Platform Target from "Any CPU" to "x86".

The good thing is, this one is really easily and deterministically to analyze: Either, the msi package is really not installed on the system or you're doing something wrong. Of course the correct call is:

msiexec /x {A4BFF20C-A21E-4720-88E5-79D5A5AEB2E8}

(Admin rights needed of course- With curly braces without any quotes here- quotes are only needed, if paths or values with blank are specified in the commandline.)
If the message is: "This action is only valid for products that are currently installed", then this is true. Either the package with this ProductCode is not installed or there is a typo.

To verify where the fault is:

1. First try to right click on the (probably) installed .msi file itself. You will see (besides "Install" and "Repair") an Uninstall entry. Click on that.
   a) If that uninstall works, your msi has another ProductCode than you expect (maybe you have the wrong WiX source or your build has dynamic logging where the ProductCode changes).
   b) If that uninstall gives the same "...only valid for products already installed" the package is not installed (which is obviously a precondition to be able to uninstall it).

2. If 1.a) was the case, you can look for the correct ProductCode of your package, if you open your msi file with Orca, Insted or another editor/tool. Just google for them. Look there in the table with the name "Property" and search for the string "ProductCode" in the first column. In the second column there is the correct value.

There are no other possibilities.

Just a suggestion for the used commandline: I would add at least the "/qb" for a simple progress bar or "/qn" parameter (the latter for complete silent uninstall, but makes only sense if you are sure it works).

Yet another option is to use the decimal module:

import numpy as np
from decimal import *

arr = np.array([  56.83,  385.3 ,    6.65,  126.63,   85.76,  192.72,  112.81, 10.55])
arr2 = [str(Decimal(i).quantize(Decimal('.01'))) for i in arr]

# ['56.83', '385.30', '6.65', '126.63', '85.76', '192.72', '112.81', '10.55']

For me, NewsBlur, Hacker News Reader and Astrid were the most helpful. Still, I don't know whether they are "suitable for basic learning".

Recommended solution is to install and trust a self-signed certificate (root). Assuming you created your own CA and the hierarchy of the certificated is correct you don't need to change the server trust evaluation. This is recommended because it doesn't require any changes in the code.

1. Generate CA and the certificates (you can use openssl: Generating CA and self-signed certificates.
2. Install root certificate (*.cer file) on the device - you can open it by Safari and it should redirect you to Settings
3. When the certificated is installed, go to Certificate Trust Settings (Settings > General > About > Certificate Trust Settings) as in MattP answer.

If it is not possible then you need to change server trust evaluation.

For me the issue appeared because my string file could not be parsed. I wanted to have a value like '%s - %s'. However this appeared to be triggering a problem, it seems string will try to parse this value in a special way. Because two string values were provided in a single value an error was written in the console, but I had so many errors triggered from that, that the initial error was hidden, because of small console buffer. Adding formatted="false" attribute to this string value of mine fixed the problem in the string file (which btw was not reported as compilation error in the file itself) and I was able to build once more.

A broader solution, adding the possibility to replace the suffix (you can remove by replacing with the empty string) and to set the maximum number of replacements:

def replacesuffix(s,old,new='',limit=1):
    """
    String suffix replace; if the string ends with the suffix given by parameter `old`, such suffix is replaced with the string given by parameter `new`. The number of replacements is limited by parameter `limit`, unless `limit` is negative (meaning no limit).

    :param s: the input string
    :param old: the suffix to be replaced
    :param new: the replacement string. Default value the empty string (suffix is removed without replacement).
    :param limit: the maximum number of replacements allowed. Default value 1.
    :returns: the input string with a certain number (depending on parameter `limit`) of the rightmost occurrences of string given by parameter `old` replaced by string given by parameter `new`
    """
    if s[len(s)-len(old):] == old and limit != 0:
        return replacesuffix(s[:len(s)-len(old)],old,new,limit-1) + new
    else:
        return s

In your case, given the default arguments, the desired result is obtained with:

replacesuffix('abcdc.com','.com')
>>> 'abcdc'

Some more general examples:

replacesuffix('whatever-qweqweqwe','qwe','N',2)
>>> 'whatever-qweNN'

replacesuffix('whatever-qweqweqwe','qwe','N',-1)
>>> 'whatever-NNN'

File directory = cw.getDir("media", Context.MODE_PRIVATE);

As always, refer to documentation, ContextWrapper has a lot to offer.

View.performClick();

http://developer.android.com/reference/android/view/View.html#performClick()

this should answer all your problems. every View inherits this function, including Button, Spinner, etc.

Just to clarify, View does not have a static performClick() method. You must call performClick() on an instance of View. For example, you can't just call

View.performClick();

Instead, do something like:

View myView = findViewById(R.id.myview);
myView.performClick();

simply run following on terminal if you don't have pip installed on your mac.

Eclipse Indigo + M2Eclipse 1.0 makes it very easy.

If you don't already have the Git connector for M2Eclipse install it. M2Eclipse will help you along by prompting you on the Import menu.

1. Select the "Import..." context menu from the Package Explorer view
2. Select "Check out Maven projects from SCM" option under the Maven category
3. On the window that is presented choose the link "Find more SCM connectors in the m2e Marketplace
4. Find connector for Git...install...restart

Note that in the search box you may have to enter "EGit" instead of "Git" to find the right connector.

With that done, simply go to the EGit repository, bring up the context menu for the Working directory and select "Import Maven projects...".

Done!

If you want to get stored procedures using specific column only, you can use try this query:

SELECT DISTINCT Name
FROM sys.Procedures
WHERE object_definition(OBJECT_ID) LIKE '%CreatedDate%';

If you want to get stored procedures using specific column of table, you can use below query :

SELECT DISTINCT Name 
FROM sys.procedures
WHERE OBJECT_DEFINITION(OBJECT_ID) LIKE '%tbl_name%'
AND OBJECT_DEFINITION(OBJECT_ID) LIKE '%CreatedDate%';

From the bash manpage:

When bash is invoked as an interactive login shell, or as a non-interactive shell with the --login option, it first reads and executes commands from the file /etc/profile, if that file exists. After reading that file, it looks for ~/.bash_profile, ~/.bash_login, and ~/.profile, in that order, and reads and executes commands from the first one that exists and is readable. The --noprofile option may be used when the shell is started to inhibit this behavior.

When a login shell exits, bash reads and executes commands from the file ~/.bash_logout, if it exists.

When an interactive shell that is not a login shell is started, bash reads and executes commands from ~/.bashrc, if that file exists. This may be inhibited by using the --norc option. The --rcfile file option will force bash to read and execute commands from file instead of ~/.bashrc.

Thus, if you want to get the same behavior for both login shells and interactive non-login shells, you should put all of your commands in either .bashrc or .bash_profile, and then have the other file source the first one.

'parent.relativePath' points at wrong local POM @ myGroup:myParentArtifactId:1.0, C:\myProjectDir\parent\pom.xml

This indicates that maven did search locally for the parent pom, but found that it was not the correct pom.

• Does pom.xml of parentpom correctly define the parent pom as the pom.xml of rootpom?
• Does rootpom folder contain pom.xml as well as the paretpom folder?

Though I agree with others that you could use count() to get the total number of rows, here is how you can use the row_count():

1. To get the total no of rows:

   with temp as (
       select row_number() over (order by id) as rownum
       from table_name 
   )
   select max(rownum) from temp

2. To get the row numbers where name is Matt:

   with temp as (
       select name, row_number() over (order by id) as rownum
       from table_name
   )
   select rownum from temp where name like 'Matt'

You can further use min(rownum) or max(rownum) to get the first or last row for Matt respectively.

These were very simple implementations of row_number(). You can use it for more complex grouping. Check out my response on Advanced grouping without using a sub query

The difference between an array evaluating its values to true or if its empty.

The method empty? comes from the Array class
http://ruby-doc.org/core-2.0.0/Array.html#method-i-empty-3F

It's used to check if the array contains something or not. This includes things that evaluate to false, such as nil and false.

>> a = []
=> []
>> a.empty?
=> true
>> a = [nil, false]
=> [nil, false]
>> a.empty?
=> false
>> a = [nil]
=> [nil]
>> a.empty?
=> false

The method any? comes from the Enumerable module.
http://ruby-doc.org/core-2.0.0/Enumerable.html#method-i-any-3F

It's used to evaluate if "any" value in the array evaluates to true. Similar methods to this are none?, all? and one?, where they all just check to see how many times true could be evaluated. which has nothing to do with the count of values found in a array.

case 1

>> a = []
=> []
>> a.any?
=> false
>> a.one?
=> false
>> a.all?
=> true
>> a.none?
=> true

case 2

>> a = [nil, true]
=> [nil, true]
>> a.any?
=> true

I was receiving this error CastError: Cast to ObjectId failed for value “[object Object]” at path “_id” after creating a schema, then modifying it and couldn't track it down. I deleted all the documents in the collection and I could add 1 object but not a second. I ended up deleting the collection in Mongo and that worked as Mongoose recreated the collection.

Register org.springframework.http.converter.json.MappingJacksonHttpMessageConverter as the message converter and return the object directly from the method.

<bean class="org.springframework.web.servlet.mvc.annotation.AnnotationMethodHandlerAdapter">
  <property name="webBindingInitializer">
    <bean class="org.springframework.web.bind.support.ConfigurableWebBindingInitializer"/>
  </property>
  <property name="messageConverters">
    <list>
      <bean class="org.springframework.http.converter.json.MappingJacksonHttpMessageConverter"/>
    </list>
  </property>
</bean>

and the controller:

@RequestMapping(method=RequestMethod.GET, value="foo/bar")
public @ResponseBody Object fooBar(){
    return myService.getActualObject();
}

This requires the dependency org.springframework:spring-webmvc.

MySQL 8.0.16 is the first version that supports CHECK constraints.

Read https://dev.mysql.com/doc/refman/8.0/en/create-table-check-constraints.html

If you use MySQL 8.0.15 or earlier, the MySQL Reference Manual says:

The CHECK clause is parsed but ignored by all storage engines.

Try a trigger...

mysql> delimiter //
mysql> CREATE TRIGGER trig_sd_check BEFORE INSERT ON Customer 
    -> FOR EACH ROW 
    -> BEGIN 
    -> IF NEW.SD<0 THEN 
    -> SET NEW.SD=0; 
    -> END IF; 
    -> END
    -> //
mysql> delimiter ;

Hope that helps.

The guide by Ani Menon (thx!) almost worked for me on windows 10, i just had to get a newer winutils.exe off that git (currently hadoop-2.8.1): https://github.com/steveloughran/winutils

here's another method to center everything within anything.

Working Fiddle

HTML: (simple as ever)

<div class="Container">
    <div class="Content"> /*this can be an img, span, or everything else*/
        I'm the Content
    </div>
</div>

CSS:

.Container
{
    text-align: center;
}

    .Container:before
    {
        content: '';
        height: 100%;
        display: inline-block;
        vertical-align: middle;
    }

.Content
{
    display: inline-block;
    vertical-align: middle;
}

Benefits

The Container and Content height are unknown.

Centering without specific negative margin, without setting the line-height (so it works well with multiple line of text) and without a script, also Works great with CSS transitions.

 ALTER TABLE YourTable ALTER COLUMN YourColumn columnType NULL

Note that the "if ($str)" and "IsNullOrEmpty" tests don't work comparably in all instances: an assignment of $str=0 produces false for both, and depending on intended program semantics, this could yield a surprise.

If you are a linux user Update node to a later version by running

sudo apt update

 sudo apt install build-essential checkinstall libssl-dev

curl -o- https://raw.githubusercontent.com/creationix/nvm/v0.35.1/install.sh | bash

nvm --version

nvm ls

nvm ls-remote

nvm install [version.number]

this should solve your problem

This will do it for you:

var yourSelect = document.getElementById( "your-select-id" );
alert( yourSelect.options[ yourSelect.selectedIndex ].value )

Declare the a element as display: inline-block and drop the width and height from the li element.

Alternatively, apply a float: left to the li element and use display: block on the a element. This is a bit more cross browser compatible, as display: inline-block is not supported in Firefox <= 2 for example.

The first method allows you to have a dynamically centered list if you give the ul element a width of 100% (so that it spans from left to right edge) and then apply text-align: center.

Use line-height to control the text's Y-position inside the element.

As mentioned in the other answers, here and here, the cache can be cleared by using:

$templateCache.removeAll();

However as suggested by gatoatigrado in the comment, this only appears to work if the html template was served without any cache headers.

So this works for me:

In angular:

app.run(['$templateCache', function ( $templateCache ) {
    $templateCache.removeAll(); }]);

You may be adding cache headers in a variety of ways but here are a couple of solutions that work for me.

If using IIS, add this to your web.config:

<location path="scripts/app/views">
  <system.webServer>
    <staticContent>
      <clientCache cacheControlMode="DisableCache" />
    </staticContent>
  </system.webServer>
</location>

If using Nginx, you can add this to your config:

location ^~ /scripts/app/views/ {
    expires -1;   
}

Edit

I just realised that the question mentioned dev machine but hopefully this may still help somebody...

Here is a solution for the single column search using PATINDEX.
It also displays the StartPosition, InvalidCharacter and ASCII code.

select line,
  patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line) as [Position],
  substring(line,patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line),1) as [InvalidCharacter],
  ascii(substring(line,patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line),1)) as [ASCIICode]
from  staging.APARMRE1
where patindex('%[^ !-~]%' COLLATE Latin1_General_BIN,Line) >0

You'll have to use svn directly:

svn checkout URL[@REV]... [PATH]

and

svn help co

gives you a little more help.

table align="center" ... this aligns the table center of page.

Using td align="center" centers the content inside that td, useful for centered aligned text but you will have issues with some email clients centering content in sub level tables so using using td align as a top level method of centering your "container" table on the page is not the way to do it. Use table align instead.

Still use your 100% wrapper table too, purely as a wrapper for the body, as some email clients don't display body background colors but it will show it with the 100% table, so add your body color to both body and the 100% table.

I could go on and on for ages about all the quirks of html email dev. All I can say is test test and test again. Litmus.com is a great tool for testing emails.

The more you do the more you will learn about what works in what email clients.

Hope this helps.

On OpenSUSE 15.3 systemd log reported this error (insmod suggestion was unhelpful).

Feb 18 08:36:38 vagrant-openSUSE-Leap dockerd[20635]: iptables v1.6.2: can't initialize iptables table `nat': Table does not exist (do you need to insmod?)

REBOOT fixed the problem

I went through this when trying to get a clientcert and private key out of a keystore.

The link above posted by welsh was great, but there was an extra step on my redhat distribution. If curl is built with NSS ( run curl --version to see if you see NSS listed) then you need to import the keys into an NSS keystore. I went through a bunch of convoluted steps, so this may not be the cleanest way, but it got things working

So export the keys into .p12

keytool -importkeystore -srckeystore $jksfile -destkeystore $p12file \
        -srcstoretype JKS -deststoretype PKCS12 \
        -srcstorepass $jkspassword -deststorepass $p12password  
        -srcalias $myalias -destalias $myalias \
        -srckeypass $keypass -destkeypass $keypass -noprompt

And generate the pem file that holds only the key

 echo making ${fileroot}.key.pem
 openssl pkcs12 -in $p12 -out ${fileroot}.key.pem  \
         -passin pass:$p12password  \
         -passout pass:$p12password  -nocerts

• Make an empty keystore:

mkdir ~/nss
chmod 700 ~/nss
certutil -N -d ~/nss

• Import the keys into the keystore

pks12util -i <mykeys>.p12 -d ~/nss -W <password for cert >

Now curl should work.

curl --insecure --cert <client cert alias>:<password for cert> \
     --key ${fileroot}.key.pem  <URL>

As I mentioned, there may be other ways to do this, but at least this was repeatable for me. If curl is compiled with NSS support, I was not able to get it to pull the client cert from a file.

In my project , I use the XMLHttpRequest to send multipart/form-data. I think it will fit you to.

and the uploader code

let xhr = new XMLHttpRequest();
xhr.open('POST', 'http://www.example.com/rest/api', true);
xhr.withCredentials = true;
xhr.send(formData);

Here is example : https://github.com/wangzilong/angular2-multipartForm

Use String.PadLeft like this:

var result = input.ToString().PadLeft(length, '0');

Have you try first remove duplicates in the subquery?

INSERT INTO destTable
SELECT source.* FROM(
    SELECT *
    FROM srcTable
    EXCEPT
    SELECT src.* FROM
    srcTable AS src
    INNER JOIN destTable AS dest 
    /* put in below line the conditions to match repeated registers */
        ON dest.SOME_FANCY_MATCH = src.SOME_FANCY_MATCH AND ... 
) as source

If the sets are very large, maybe this is not the best solution.

you can try below code

1- model or view model

public class UploadImage 
{
  public string ImageFile { get; set; }
  public string ImageName { get; set; }
  public string ImageDescription { get; set; }
}

2- View page

<form class="form-horizontal" asp-controller="Image" asp-action="UploadImage" method="POST" enctype="multipart/form-data">

<input type="file" asp-for="ImageFile">
<input type="text" asp-for="ImageName">
<input type="text" asp-for="ImageDescription">
</form>

3- Controller

 public class Image
    {

      private IHostingEnvironment _hostingEnv;
      public Image(IHostingEnvironment hostingEnv)
      {
         _hostingEnv = hostingEnv;
      }

      [HttpPost]
      public async Task<IActionResult> UploadImage(UploadImage model, IFormFile ImageFile)
      {
        if (ModelState.IsValid)
         {
        var filename = ContentDispositionHeaderValue.Parse(ImageFile.ContentDisposition).FileName.Trim('"');
        var path = Path.Combine(Directory.GetCurrentDirectory(), "wwwroot", "images", ImageFile.FileName);
        using (System.IO.Stream stream = new FileStream(path, FileMode.Create))
         {
            await ImageFile.CopyToAsync(stream);
         }
          model.ImageFile = filename;
         _context.Add(model);
         _context.SaveChanges();
         }        

      return RedirectToAction("Index","Home");   
    }

Regex.Replace(strInput, strToken.Replace("$", "[$]"), strReplaceWith, RegexOptions.IgnoreCase);

Posix governs interoperability, portability, and in other areas such as the usage and mechanism of fork, permissions and filesystem standards such as /etc, /var, /usr and so on . Hence, when developers write a program under a Posix compliant system such as for example Linux, it is generally, not always, guaranteed to run on another posix compliant system such as IBM's AIX system or other commercial variants of Unix. Posix is a good thing to have as such it eases the software development for maximum portability which it strives for. Hope this answer makes sense.

Thanks to Jed Smith & Tinkertim for pointing out my error - my bad!!! :(

code that works, but output is:

10
20
30
40
50

so:

    List<Integer> myCoords = new ArrayList<Integer>();
    myCoords.add(10);
    myCoords.add(20);
    myCoords.add(30);
    myCoords.add(40);
    myCoords.add(50);
    for (Integer number : myCoords) {
        System.out.println(number);
        try {
            Thread.sleep(2000);
        } catch (InterruptedException e) {
            e.printStackTrace();
        }
    }

You can use this

"abcdefg".index('c')   #=> 2

sys.argv represents the command line options you execute a script with.

sys.argv[0] is the name of the script you are running. All additional options are contained in sys.argv[1:].

You are attempting to open a file that uses sys.argv[1] (the first argument) as what looks to be the directory.

Try running something like this:

python ConcatenateFiles.py /tmp

Even though this is an old thread, I thought I would weigh in as I had to deal with this lately.

You should not use rowCount for SELECT statements as it is not portable. I use the isset function to test if a select statement worked:

$today = date('Y-m-d', strtotime('now'));

$sth = $db->prepare("SELECT id_email FROM db WHERE hardcopy = '1' AND hardcopy_date <= :today AND hardcopy_sent = '0' ORDER BY id_email ASC");

//I would usually put this all in a try/catch block, but kept it the same for continuity
if(!$sth->execute(array(':today'=>$today))) 
{
    $db = null ;
    exit();
}

$result = $sth->fetch(PDO::FETCH_OBJ)

if(!isset($result->id_email))
{
    echo "empty";
}
else
{
    echo "not empty, value is $result->id_email";
}

$db = null;

Of course this is only for a single result, as you might have when looping over a dataset.

The JavaScript Object() constructor makes an Object that you can assign members to.

myObj = new Object()
myObj.key = value;
myObj[key2] = value2;   // Alternative

I got that error message in code line containing SqlConnection.Open() running my .NET code as x64 application. Running as x86 causing no errors.

Solution was to deactivate the Force protocol encryption option for TCP/IP in %windir%\System32\cliconfg.exe

Force protocol encryption

From the docs:

If no encoding is specified, then the raw buffer is returned.

Which might explain the <Buffer ...>. Specify a valid encoding, for example utf-8, as your second parameter after the filename. Such as,

fs.readFile("test.txt", "utf8", function(err, data) {...});

I know this answer is a bit late.
My purpose for this answer is for everyone's reference should they encounter this type of challenge with SQLite now or in the future and they're having a hard time with it.

Now, looking back at your query, it should be something like this.

CREATE TABLE people (id integer primary key autoincrement, first_name varchar(20), last_name varchar(20));

It works on my end. Like so,

Just in case you are working with SQLite, I suggest for you to check out DB Browser for SQLite. Works on different platforms as well.

It's nothing complicated. We cannot use getFragmentManager() here. For using Fragments inside a Fragment, we use getChildFragmentManager(). Rest will be the same.

The best way to remember this is that the order of for loop inside the list comprehension is based on the order in which they appear in traditional loop approach. Outer most loop comes first, and then the inner loops subsequently.

So, the equivalent list comprehension would be:

[entry for tag in tags for entry in entries if tag in entry]

In general, if-else statement comes before the first for loop, and if you have just an if statement, it will come at the end. For e.g, if you would like to add an empty list, if tag is not in entry, you would do it like this:

[entry if tag in entry else [] for tag in tags for entry in entries]

@Gadde - your answer was very helpful. Thank you! I needed a "Maps"-like zoom for a div and was able to produce the feel I needed with your post. My criteria included the need to have the click repeat and continue to zoom out/in with each click. Below is my final result.

    var currentZoom = 1.0;

    $(document).ready(function () {
        $('#btn_ZoomIn').click(
            function () {
                $('#divName').animate({ 'zoom': currentZoom += .1 }, 'slow');
            })
        $('#btn_ZoomOut').click(
            function () {
                $('#divName').animate({ 'zoom': currentZoom -= .1 }, 'slow');
            })
        $('#btn_ZoomReset').click(
            function () {
                currentZoom = 1.0
                $('#divName').animate({ 'zoom': 1 }, 'slow');
            })
    });

The currently accepted answer is incorrect - document.documentElement.scrollTop always returns 0 on Chrome. This is because WebKit uses body for keeping track of scrolling, whereas Firefox and IE use html.

To get the current position, you want:

document.documentElement.scrollTop || document.body.scrollTop

You can set the current position to 1000px down the page like so:

document.documentElement.scrollTop = document.body.scrollTop = 1000;

Or, using jQuery (animate it while you're at it!):

$("html, body").animate({ scrollTop: "1000px" });

To add the privileges needed to the files add and grant right to the following local user: SQLServerMSSQLUser$COMPUTERNAME$INSTANCENAME, where COMPUTERNAME and INSTANCENAME has to be replaced with name of computer and MSSQL instance respectively.

step 1:- Download volley.jar file.

step 2:- Go to your project and set the display menu from Android to Project then go to

app -> libs-> paste your volley.jar file here

step 3:- Right click on the volley.jar file and click on "add as library". and its all done.

Check your X Window environment variables using the "env" command.

sudo sh -c "echo /usr/lib/oracle/12.2/client64/lib > /etc/ld.so.conf.d/oracle-instantclient.conf";sudo ldconfig

from https://help.ubuntu.com/community/Oracle%20Instant%20Client

It's empty by default. You'll find a bunch of settings in /etc/apache2/apache2.conf.

In there it does this:

# Include all the user configurations:
Include httpd.conf

The correct syntax is:

data: {status: status, name: name},

As specified here: http://api.jquery.com/jQuery.ajax/

So if that doesn't work, I would alert those variables to make sure they have values.

Modules Preconditions:

The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (precondition="managedHandler") only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:

<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />

If you remove the attribute precondition="managedHandler", Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.

You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "managedHandler" precondition.

To enable all managed modules to run for all requests without configuring each module entry to remove the "managedHandler" precondition, use the runAllManagedModulesForAllRequests property in the <modules> section:

<modules runAllManagedModulesForAllRequests="true" />    

When you use this property, the "managedHandler" precondition has no effect and all managed modules run for all requests.

Copied from IIS Modules Overview: Preconditions

Create your partial view something like:

@model YourModelType
<div>
  <!-- HTML to render your object -->
</div>

Then in your view use:

@Html.Partial("YourPartialViewName", Model)

If you do not want a strongly typed partial view remove the @model YourModelType from the top of the partial view and it will default to a dynamic type.

Update

The default view engine will search for partial views in the same folder as the view calling the partial and then in the ~/Views/Shared folder. If your partial is located in a different folder then you need to use the full path. Note the use of ~/ in the path below.

@Html.Partial("~/Views/Partials/SeachResult.cshtml", Model)

~/.gradle/gradle.properties:

mavenUser=admin
mavenPassword=admin123

build.gradle:

...
authentication(userName: mavenUser, password: mavenPassword)

$.getJSON() is a kind of abstraction of a regular AJAX call where you would have to tell that you want a JSON encoded response.

$.ajax({
  url: url,
  dataType: 'json',
  data: data,
  success: callback
});

You can handle errors in two ways: generically (by configuring your AJAX calls before actually calling them) or specifically (with method chain).

'generic' would be something like:

$.ajaxSetup({
      "error":function() { alert("error");  }
});

And the 'specific' way:

$.getJSON("example.json", function() {
  alert("success");
})
.done(function() { alert("second success"); })
.fail(function() { alert("error"); })
.always(function() { alert("complete"); });

Late answering, probably everybody knows about yield now, but some better documentation has come along.

Adapting an example from "Javascript's Future: Generators" by James Long for the official Harmony standard:

function * foo(x) {
    while (true) {
        x = x * 2;
        yield x;
    }
}

"When you call foo, you get back a Generator object which has a next method."

var g = foo(2);
g.next(); // -> 4
g.next(); // -> 8
g.next(); // -> 16

So yield is kind of like return: you get something back. return x returns the value of x, but yield x returns a function, which gives you a method to iterate toward the next value. Useful if you have a potentially memory intensive procedure that you might want to interrupt during the iteration.

The problem here is very simple. If you want to display value in JSP, you have to use <%= %> tag instead of <% %>, here is the solved code:

<tr> <td><%=rs.getInt("ID") %></td> <td><%=rs.getString("NAME") %></td> <td><%=rs.getString("SKILL") %></td> </tr>

In version 5.2.7 I use this to send plain text: $mail->set('Body', $Body);

You can hit the key q (for quit) and it should take you to the prompt.

Please see this link.

How about pcntl_fork?

check our the manual page for examples: PHP pcntl_fork

<?php

    $pid = pcntl_fork();
    if ($pid == -1) {
        die('could not fork');
    } else if ($pid) {
        // we are the parent
        pcntl_wait($status); //Protect against Zombie children
    } else {
        // we are the child
    }

?>

Old question, but hopefully this'll help someone else.

In my case I was using a toolchain on Ubuntu 12.04 that was built on Ubuntu 10.04 (requires GCC 4.1 to build). As most of the libraries have moved to multiarch dirs, it couldn't find ld.so. So, make a symlink for it.

Check required path:

$ readelf -a arm-linux-gnueabi-gcc | grep interpreter:
      [Requesting program interpreter: /lib/ld-linux-x86-64.so.2]

Create symlink:

$ sudo ln -s /lib/x86_64-linux-gnu/ld-linux-x86-64.so.2 /lib/ld-linux-x86-64.so.2

If you're on 32bit, it'll be i386-linux-gnu and not x86_64-linux-gnu.

You can combine the best method into one line or function, and have the new query auto-generated for you:

function getRowCount($q){ 
    global $db;
    return $db->query(preg_replace('/SELECT [A-Za-z,]+ FROM /i','SELECT count(*) FROM ',$q))->fetchColumn();
}

$numRows = getRowCount($query);

You have chosen not only a realistic path, but arguably one of the best ecosystems strongly backed(also X-platforms) by MS. Still you should consider following points:

• Update: Main doc about .Net platform standard is here: https://github.com/dotnet/corefx/blob/master/Documentation/architecture/net-platform-standard.md
• Update: Current Mono 4.4.1 cannot run latest Asp.Net core 1.0 RTM
• Although mono is more feature complete, its future is unclear, because MS owns it for some months now and its a duplicate work for them to support it. But MS is definitely committed to .Net Core and betting big on it.
• Although .Net core is released, the 3rd party ecosystem is not quite there. For example Nhibernate, Umbraco etc cannot run over .Net core yet. But they have a plan.
• There are some features missing in .Net Core like System.Drawing, you should look for 3rd party libraries
• You should use nginx as front server with kestrelserver for asp.net apps, because kestrelserver is not quite ready for production. For example HTTP/2 is not implemented.

I hope it helps

You can create a countdown timer using applet, below is the code,

    * Place the mouse over the applet to pause the count; move it off to resume.
    * This class demonstrates most applet methods and features.

There's a simple online tool that can do this called sqlizer.io.

You upload an XLSX file to it, enter a sheet name and cell range, and it will generate a CREATE TABLE statement and a bunch of INSERT statements to import all your data into a MySQL database.

(Disclaimer: I help run SQLizer)

This one drove me crazy... basically you need two things:

1) Make sure your DNS is setup to point to your subdomain. This means to make sure you have an A Record in the DNS for your subdomain and point to the same IP.

2) You must add an additional website in IIS 7 named subdomain.example.com

• Sites > Add Website
• Site Name: subdomain.example.com
• Physical Path: select the subdomain directory
• Binding: same ip as example.com
• Host name: subdomain.example.com

I ran $hadoop namenode to start namenode manually at foreground.

From the logs I figured out that 50070 is ocuupied, which was defaultly used by dfs.namenode.http-address. After configuring dfs.namenode.http-address in hdfs-site.xml, everything went well.

There is also another way to convert between SecureString and String.

1. String to SecureString

SecureString theSecureString = new NetworkCredential("", "myPass").SecurePassword;

2. SecureString to String

string theString = new NetworkCredential("", theSecureString).Password;

Here is the link

Filter() from the base package is the perfect function for that use-case: You simply have to code:

Filter(is.numeric, x)

It is also much faster than select_if():

library(microbenchmark)
microbenchmark(
    dplyr::select_if(mtcars, is.numeric),
    Filter(is.numeric, mtcars)
)

returns (on my computer) a median of 60 microseconds for Filter, and 21 000 microseconds for select_if (350x faster).

try this

select max(salary) as first, 
       (select salary from employee order by salary desc limit 1, 1) as second 
from employee limit 1

Probably a silly suggestion compared to others:

if(!preg_match("/^[a-zA-Z0-9]$/",$string)){
    $sortedString=preg_replace("/^[a-zA-Z0-9]+$/","",$string);
}

Comparing map, applymap and apply: Context Matters

First major difference: DEFINITION

• map is defined on Series ONLY
• applymap is defined on DataFrames ONLY
• apply is defined on BOTH

Second major difference: INPUT ARGUMENT

• map accepts dicts, Series, or callable
• applymap and apply accept callables only

Third major difference: BEHAVIOR

• map is elementwise for Series
• applymap is elementwise for DataFrames
• apply also works elementwise but is suited to more complex operations and aggregation. The behaviour and return value depends on the function.

Fourth major difference (the most important one): USE CASE

• map is meant for mapping values from one domain to another, so is optimised for performance (e.g., df['A'].map({1:'a', 2:'b', 3:'c'}))
• applymap is good for elementwise transformations across multiple rows/columns (e.g., df[['A', 'B', 'C']].applymap(str.strip))
• apply is for applying any function that cannot be vectorised (e.g., df['sentences'].apply(nltk.sent_tokenize))

Summarising

Footnotes

1. map when passed a dictionary/Series will map elements based on the keys in that dictionary/Series. Missing values will be recorded as NaN in the output.

2. applymap in more recent versions has been optimised for some operations. You will find applymap slightly faster than apply in some cases. My suggestion is to test them both and use whatever works better.

3. map is optimised for elementwise mappings and transformation. Operations that involve dictionaries or Series will enable pandas to use faster code paths for better performance.

4. Series.apply returns a scalar for aggregating operations, Series otherwise. Similarly for DataFrame.apply. Note that apply also has fastpaths when called with certain NumPy functions such as mean, sum, etc.

You can't link to file:/// from an HTML document that is not itself a file:/// for security reasons.

Be aware that if your string number contains more than 15 significant digits float(s) will round it.In those cases it is better to use Decimal

Here is an explanation and some code samples: https://docs.python.org/3/library/sys.html#sys.float_info

I am not 100% sure if this works all the time, but in my application this gives me the expected behavior.

Lets say you are on ABOUT page and you have the following route:

yourApp.config(['$routeProvider', 
    function($routeProvider) {
        $routeProvider.
            when('/about', {
                templateUrl: 'about.html',
                controller: 'AboutCtrl'
            }).
            otherwise({
                redirectTo: '/'
            });
        }
]);

Now, in you HTML

<ul>
    <li><a href="#/about#tab1">First Part</a></li>
    <li><a href="#/about#tab2">Second Part</a></li>
    <li><a href="#/about#tab3">Third Part</a></li>                      
</ul>

<div id="tab1">1</div>
<div id="tab2">2</div>
<div id="tab3">3</div>

In conclusion

Including the page name before the anchor did the trick for me. Let me know about your thoughts.

Downside

This will re-render the page and then scroll to the anchor.

UPDATE

A better way is to add the following:

<a href="#tab1" onclick="return false;">First Part</a>

One liner:

if (DateTime.TryParse(value, out _)) {//dostuff}

Simple and easy way to update the cursor

UPDATE Cursor
SET Cursor.CODE = Cursor.New_CODE
FROM (
  SELECT CODE, ROW_NUMBER() OVER (ORDER BY [CODE]) AS New_CODE
  FROM Table Where CODE BETWEEN 1000 AND 1999
  ) Cursor

NSString *str1 = @"Share Role Play Photo via Facebook, or Twitter for free coins per photo.";
NSString *str2 = @"Like Role Play on facebook for 50 free coins.";
NSString *str3 = @"Check out 'What's Hot' on other ways to receive free coins";


NSString *msg = [NSString stringWithFormat:@"%@\n%@\n%@", str1, str2, str3];

by using replaceChild():

<html>
<head>
</head>
<body>
  <div>
    <a id="myAnchor" href="http://www.stackoverflow.com">StackOverflow</a>
  </div>
<script type="text/JavaScript">
  var myAnchor = document.getElementById("myAnchor");
  var mySpan = document.createElement("span");
  mySpan.innerHTML = "replaced anchor!";
  myAnchor.parentNode.replaceChild(mySpan, myAnchor);
</script>
</body>
</html>

Easiest way to clear/reset the text field on click is to clear/reset the scope

<input type="text" class="form-control" ng-model="searchAll" ng-click="clearfunction(this)"/>

In Controller

$scope.clearfunction=function(event){
   event.searchAll=null;
}

Better:

Integer.valueOf(i).toString()

Did you mean "Complex" as in complex number with real and imaginary parts? This seems unlikely, so if not you'd have to give an example since "complex" means nothing specific in terms of the C language.

You will get a direct memory copy of the structure; whether that is what you want depends on the structure. For example if the structure contains a pointer, both copies will point to the same data. This may or may not be what you want; that is down to your program design.

To perform a 'smart' copy (or a 'deep' copy), you will need to implement a function to perform the copy. This can be very difficult to achieve if the structure itself contains pointers and structures that also contain pointers, and perhaps pointers to such structures (perhaps that's what you mean by "complex"), and it is hard to maintain. The simple solution is to use C++ and implement copy constructors and assignment operators for each structure or class, then each one becomes responsible for its own copy semantics, you can use assignment syntax, and it is more easily maintained.

Here is a generic JS which should work in most browsers (FF, Cr, IE6+):

var viewportHeight;
var viewportWidth;
if (document.compatMode === 'BackCompat') {
    viewportHeight = document.body.clientHeight;
    viewportWidth = document.body.clientWidth;
} else {
    viewportHeight = document.documentElement.clientHeight;
    viewportWidth = document.documentElement.clientWidth;
}

I know this is an old post, but I just found this piece of gold. This is old (2006), but still works with IE9. I personnally added a bookmark with this.

Just copy paste this in your browser's address bar:

javascript:void(window.open("javascript:document.open(\"text/plain\");document.write(opener.document.body.parentNode.outerHTML)"))

As for firefox, web developper tool bar does the job. I usually use this, but sometimes, some dirty 3rd party asp.net controls generates differents markups based on the user agent...

EDIT

As Bryan pointed in the comment, some browser remove the javascript: part when copy/pasting in url bar. I just tested and that's the case with IE10.

I got same problem if i understand your question correctly, I want to know the last inserted id after every insert performance in SQLite operation. i tried the following statement:

select * from table_name order by id desc limit 1

The id is the first column and primary key of the table_name, the mentioned statement show me the record with the largest id.

But the premise is u never deleted any row so the numbers of id equal to the numbers of rows.

Here is one way to do it. Involves doing a little PHP as well.

The PHP part:

$filenameArray = [];

$handle = opendir(dirname(realpath(__FILE__)).'/images/');
        while($file = readdir($handle)){
            if($file !== '.' && $file !== '..'){
                array_push($filenameArray, "images/$file");
            }
        }

echo json_encode($filenameArray);

The jQuery part:

$.ajax({
            url: "getImages.php",
            dataType: "json",
            success: function (data) {

                $.each(data, function(i,filename) {
                    $('#imageDiv').prepend('<img src="'+ filename +'"><br>');
                });
            }
        });

So basically you do a PHP file to return you the list of image filenames as JSON, grab that JSON using an ajax call, and prepend/append them to the html. You would probably want to filter the files u grab from the folder.

Had some help on the php part from 1

I am facing the same issue. If parent element is hidden then after showing the element chosen drop down are not showing. This is not a perfect solution but it solved my issue. After showing the element you can use following code.

function onshowelement() { $('.chosen').chosen('destroy'); $(".chosen").chosen({ width: '100%' }); }

I furiously read all of this page, hoping to find a solution for:

"configure: error: C compiler cannot create executables"

In the end nothing worked, because my problem was a "typing" one, and was related to CFLAGS. In my .bash_profile file I had:

export ARM_ARCH="arm64”
export CFLAGS="-arch ${ARM_ARCH}"

As you can observe --- export ARM_ARCH="arm64” --- the last quote sign is not the same with the first quote sign. The first one ( " ) is legal while the second one ( ” ) is not.
This happended because I made the mistake to use TextEdit (I'm working under MacOS), and this is apparently a feature called SmartQuotes: the quote sign CHANGES BY ITSELF TO THE ILLEGAL STYLE whenever you edit something just next to it.
Lesson learned: use a proper text editor...

If you're needing something simple, would this fit the bill?

Map<K, V> myCache = Collections.synchronizedMap(new WeakHashMap<K, V>());

It wont save to disk, but you said you wanted simple...

Links:

• Collections.synchronizedMap
• WeakHashMap

(As Adam commented, synchronising a map has a performance hit. Not saying the idea doesn't have hairs on it, but would suffice as a quick and dirty solution.)

   $(this).attr('action',$(this).attr('action')+$('#agent').val());
   $(this).submit();

Update on data.table methods for joining datasets. See below examples for each type of join. There are two methods, one from [.data.table when passing second data.table as the first argument to subset, another way is to use merge function which dispatches to fast data.table method.

df1 = data.frame(CustomerId = c(1:6), Product = c(rep("Toaster", 3), rep("Radio", 3)))
df2 = data.frame(CustomerId = c(2L, 4L, 7L), State = c(rep("Alabama", 2), rep("Ohio", 1))) # one value changed to show full outer join

library(data.table)

dt1 = as.data.table(df1)
dt2 = as.data.table(df2)
setkey(dt1, CustomerId)
setkey(dt2, CustomerId)
# right outer join keyed data.tables
dt1[dt2]

setkey(dt1, NULL)
setkey(dt2, NULL)
# right outer join unkeyed data.tables - use `on` argument
dt1[dt2, on = "CustomerId"]

# left outer join - swap dt1 with dt2
dt2[dt1, on = "CustomerId"]

# inner join - use `nomatch` argument
dt1[dt2, nomatch=NULL, on = "CustomerId"]

# anti join - use `!` operator
dt1[!dt2, on = "CustomerId"]

# inner join - using merge method
merge(dt1, dt2, by = "CustomerId")

# full outer join
merge(dt1, dt2, by = "CustomerId", all = TRUE)

# see ?merge.data.table arguments for other cases

Below benchmark tests base R, sqldf, dplyr and data.table.
Benchmark tests unkeyed/unindexed datasets. Benchmark is performed on 50M-1 rows datasets, there are 50M-2 common values on join column so each scenario (inner, left, right, full) can be tested and join is still not trivial to perform. It is type of join which well stress join algorithms. Timings are as of sqldf:0.4.11, dplyr:0.7.8, data.table:1.12.0.

Be aware there are other types of joins you can perform using data.table:
- update on join - if you want to lookup values from another table to your main table
- aggregate on join - if you want to aggregate on key you are joining you do not have to materialize all join results
- overlapping join - if you want to merge by ranges
- rolling join - if you want merge to be able to match to values from preceeding/following rows by rolling them forward or backward
- non-equi join - if your join condition is non-equal

Maybe a bit delayed, but technologies have evolved since so there is certainly new info around which draws fresh light on the matter...

As iOS has yet to open up an API for WiFi Direct and Multipeer Connectivity is iOS only, I believe the best way to approach this is to use BLE, which is supported by both platforms (some better than others).

On iOS a device can act both as a BLE Central and BLE Peripheral at the same time, on Android the situation is more complex as not all devices support the BLE Peripheral state. Also the Android BLE stack is very unstable (to date).

If your use case is feature driven, I would suggest to look at Frameworks and Libraries that can achieve cross platform communication for you, without you needing to build it up from scratch.

For example: http://p2pkit.io or google nearby

Disclaimer: I work for Uepaa, developing p2pkit.io for Android and iOS.

<form id="uploadForm" class="disp-inline" role="form" action="" method="post" enctype="multipart/form-data">
    <input type="file" name="file" id="file">
</form>
<button onclick="checkSize();"></button>
<script>
    function checkSize(){
        var size = $('#uploadForm')["0"].firstChild.files["0"].size;
        console.log(size);
    }
</script>

I found this to be the easiest if you don't plan on submitted the form through standard ajax / html5 methods, but of course it works with anything.

NOTES:

var size = $('#uploadForm')["0"]["0"].files["0"].size;

This used to work, but it doesn't in chrome anymore, i just tested the code above and it worked in both ff and chrome (lastest). The second ["0"] is now firstChild.

This error would occur if any of the following variables were actually strings or null instead of arrays, in which case accessing them with an array syntax $var[$i] would be like trying to access a specific character in a string:

$catagory
$task
$fullText
$dueDate
$empId

In short, everything in your insert query.

Perhaps the $catagory variable is misspelled?

Here's a fuller example using the amazing @AdamBardon technique.

@IBDesignable class ButtonOrSomethingWithBlur: UIButton {

    var ba: UIViewPropertyAnimator?
    private lazy var blurry: BlurryBall = { return BlurryBall() }()

    override func didMoveToSuperview() {
        super.didMoveToSuperview()
        
        // Setup the blurry ball.  BE SURE TO TEARDOWN.
        // Use superb trick to access the internal guassian level of Apple's
        // standard gpu blurrer per stackoverflow.com/a/55378168/294884
        
        superview?.insertSubview(blurry, belowSubview: self)
        ba = UIViewPropertyAnimator(duration:1, curve:.linear) {[weak self] in
            // note, those duration/curve values are simply unusued
            self?.blurry.effect = UIBlurEffect(style: .extraLight)
        }
        ba?.fractionComplete = live.largeplaybutton_blurfactor
    }
    
    override func willMove(toSuperview newSuperview: UIView?) {
        
        // Teardown for the blurry ball - critical
        
        if newSuperview == nil { print("safe teardown")
            ba?.stopAnimation(true)
            ba?.finishAnimation(at: .current)
        }
    }

    override func layoutSubviews() { super.layoutSubviews()
        blurry.frame = bounds, your drawing frame or whatever
    }

{Aside: as a general iOS engineering matter, didMoveToWindow may be more suitable to you than didMoveToSuperview. Secondly, you may use some other way to do the teardown, but the teardown is the two lines of code shown there.}

BlurryBall is just a UIVisualEffectView. Notice the inits for a visual effects view. If you happen to need rounded corners or whatever, do it in this class.

class BlurryBall: UIVisualEffectView {
    
    override init(effect: UIVisualEffect?) { super.init(effect: effect)
        commonInit() }
    
    required init?(coder aDecoder: NSCoder) { super.init(coder: aDecoder)
        commonInit() }
    
    private func commonInit() {
        clipsToBounds = true
        backgroundColor = .clear
    }
    
    override func layoutSubviews() {
        super.layoutSubviews()
        layer.cornerRadius = bounds.width / 2
    }
}

Click the arrow in the screenshot and find the bash with already running Django server. You were getting the message because your server was already running and you tried to start the server again.

Actually, you can use what Google provides via the support library RoundedBitmapDrawableFactory class (here and here), instead of using a third party library :

Gradle:

implementation 'androidx.appcompat:appcompat:1.0.0-beta01'

MainActivity.kt

class MainActivity : AppCompatActivity() {

    override fun onCreate(savedInstanceState: Bundle?) {
        super.onCreate(savedInstanceState)
        setContentView(R.layout.activity_main)
        val originalDrawable = ContextCompat.getDrawable(this, R.drawable.avatar_1)!!
        val bitmap = convertDrawableToBitmap(originalDrawable)
        val drawable = RoundedBitmapDrawableFactory.create(resources, bitmap)
        drawable.setAntiAlias(true)
        drawable.cornerRadius = Math.max(bitmap.width, bitmap.height) / 2.0f
        avatarImageView.setImageDrawable(drawable)
    }

    companion object {
        @JvmStatic
        fun convertDrawableToBitmap(drawable: Drawable): Bitmap {
            if (drawable is BitmapDrawable)
                return drawable.bitmap
            // We ask for the bounds if they have been set as they would be most
            // correct, then we check we are  > 0
            val bounds = drawable.bounds
            val width = if (!bounds.isEmpty) bounds.width() else drawable.intrinsicWidth
            val height = if (!bounds.isEmpty) bounds.height() else drawable.intrinsicHeight
            // Now we check we are > 0
            val bitmap = Bitmap.createBitmap(if (width <= 0) 1 else width, if (height <= 0) 1 else height,
                    Bitmap.Config.ARGB_8888)
            val canvas = Canvas(bitmap)
            drawable.setBounds(0, 0, canvas.width, canvas.height)
            drawable.draw(canvas)
            return bitmap
        }
    }
}

The result:

And, suppose you want to add a border on top of it, you can use this for example:

stroke_drawable.xml

<shape xmlns:android="http://schemas.android.com/apk/res/android" android:shape="oval">
    <stroke
        android:width="4dp" android:color="@android:color/black"/>
</shape>

And add android:foreground="@drawable/stroke_drawable" to the ImageView in the layout XML file, and you get this :

I'm not sure how to add shadow (that will work on older Android versions), though. Using FloatingActionButton (from the "com.google.android.material:material" dependency), I failed to make the bitmap fill the FAB itself. Using it instead could be even better if it worked.

EDIT: if you wish to add shadow of elevation (available from API 21), you can change a bit what I wrote:

Inside the layout XML file:

<androidx.appcompat.widget.AppCompatImageView android:padding="4dp"
    android:id="@+id/avatarImageView" android:layout_width="100dp" android:layout_height="100dp" android:elevation="8dp"
    android:layout_gravity="center" android:background="@drawable/stroke_drawable" tools:srcCompat="@drawable/avatar_1"/>

CircularShadowViewOutlineProvider.kt

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
class CircularShadowViewOutlineProvider : ViewOutlineProvider() {
    override fun getOutline(view: View, outline: Outline) {
        val size = Math.max(view.width, view.height)
        outline.setRoundRect(0, 0, size, size, size / 2f)
    }
}

In code:

    if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.LOLLIPOP)
        avatarImageView.outlineProvider = CircularShadowViewOutlineProvider()

Result:

If you have any access to the server at all, convert its processing to UTF-8. The art of submitting non-UTF-8 forms is a long and sorry story; this document about forms and i18n may be of interest. I understand you do not seem to care about international support; you can always convert the UTF-8 data to html entities to make sure it stays Latin-1.

If you want your application to open the link in a web browser you need to add a HyperLink with the RequestNavigate event set to a function that programmatically opens a web-browser with the address as a parameter.

<TextBlock>           
    <Hyperlink NavigateUri="http://www.google.com" RequestNavigate="Hyperlink_RequestNavigate">
        Click here
    </Hyperlink>
</TextBlock>

In the code-behind you would need to add something similar to this to handle the RequestNavigate event:

private void Hyperlink_RequestNavigate(object sender, RequestNavigateEventArgs e)
{
    // for .NET Core you need to add UseShellExecute = true
    // see https://docs.microsoft.com/dotnet/api/system.diagnostics.processstartinfo.useshellexecute#property-value
    Process.Start(new ProcessStartInfo(e.Uri.AbsoluteUri));
    e.Handled = true;
}

In addition you will also need the following imports:

using System.Diagnostics;
using System.Windows.Navigation;

It will look like this in your application:

Try this, if your input is string 
For example 

string input= "13:01";
string[] arry = input.Split(':');                  
string timeinput = arry[0] + arry[1];
private string Convert24To12HourInEnglish(string timeinput)

 {

DateTime startTime = new DateTime(2018, 1, 1, int.Parse(timeinput.Substring(0, 2)), 
int.Parse(timeinput.Substring(2, 2)), 0); 
return startTime.ToString("hh:mm tt");

}
out put: 01:01

We can use title() function with negative line value to bring down the title.

See this example:

plot(1, 1)
title("Title", line = -2)

Here's a cool one that I use in a ruby script on OS X (so that I can start a script and get an update even after toggling away from the window):

cmd = %Q|osascript -e 'display notification "Server was reset" with title "Posted Update"'|
system ( cmd )

There isn't really a formal manual, because there's no single style or standard.

So long as you understand the rules of identifier naming you can use whatever you like.

In practice, I find it easier to use lower_case_underscore_separated_identifiers because it isn't necessary to "Double Quote" them everywhere to preserve case, spaces, etc.

If you wanted to name your tables and functions "@MyA??! ""betty"" Shard$42" you'd be free to do that, though it'd be pain to type everywhere.

The main things to understand are:

• Unless double-quoted, identifiers are case-folded to lower-case, so MyTable, MYTABLE and mytable are all the same thing, but "MYTABLE" and "MyTable" are different;

• Unless double-quoted:

  SQL identifiers and key words must begin with a letter (a-z, but also letters with diacritical marks and non-Latin letters) or an underscore (_). Subsequent characters in an identifier or key word can be letters, underscores, digits (0-9), or dollar signs ($).

• You must double-quote keywords if you wish to use them as identifiers.

In practice I strongly recommend that you do not use keywords as identifiers. At least avoid reserved words. Just because you can name a table "with" doesn't mean you should.

I think I got there in the end.

The task is like this:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default({}) | combine( {item.item.name: item.stdout} ) }}"
  with_items: "{{ people.results }}"

It loops through each of the dicts (item) in the people.results array, each time creating a new dict like {Bob: "male"}, and combine()s that new dict in the genders array, which ends up like:

{
    "Bob": "male",
    "Thelma": "female"
}

It assumes the keys (the name in this case) will be unique.

I then realised I actually wanted a list of dictionaries, as it seems much easier to loop through using with_items:

- name: Populate genders
  set_fact:
    genders: "{{ genders|default([]) + [ {'name': item.item.name, 'gender': item.stdout} ] }}"
  with_items: "{{ people.results }}"

This keeps combining the existing list with a list containing a single dict. We end up with a genders array like this:

[
    {'name': 'Bob', 'gender': 'male'},
    {'name': 'Thelma', 'gender': 'female'}
]

In addition to erickson's suggestions, there's also jna, which allows you to call native libraries without using jni. It's shockingly easy to use, and I've used it on a couple of projects with great success.

The only caveat is that it's slower than jni, so if you're doing this to a very large number of files that might be an issue for you.

(Editing to add example)

Here's a complete jna chmod example:

import com.sun.jna.Library;
import com.sun.jna.Native;

public class Main {
    private static CLibrary libc = (CLibrary) Native.loadLibrary("c", CLibrary.class);

    public static void main(String[] args) {
        libc.chmod("/path/to/file", 0755);
    }
}

interface CLibrary extends Library {
    public int chmod(String path, int mode);
}

I think a better approach than setting the platform's default character set, especially as you seem to have restrictions on affecting the application deployment, let alone the platform, is to call the much safer String.getBytes("charsetName"). That way your application is not dependent on things beyond its control.

I personally feel that String.getBytes() should be deprecated, as it has caused serious problems in a number of cases I have seen, where the developer did not account for the default charset possibly changing.

I know this is an old post but i am sure that this might help someone down the road.

You can simply get the headerView element of the Navigation view by doing this:

 NavigationView mView = ( NavigationView ) findViewById( R.id.nav_view );

 if( mView != null ){
     LinearLayout mParent = ( LinearLayout ) mView.getHeaderView( 0 );

     if( mParent != null ){
        // Set your values to the image and text view by declaring and setting as you need to here. 
     }
 }

I hope that this helps someone.

I think what are attempting is semantically same as a radio button when 1 is when one of the options is selected and 0 is the other option.

I suggest using the radio button provided by Android by default.

Here is how to use it- http://www.mkyong.com/android/android-radio-buttons-example/

and the android documentation is here-

http://developer.android.com/guide/topics/ui/controls/radiobutton.html

        self.present(nextViewController, animated:true, completion:nil)

    }

Change our Controller Name RegisterNewUserViewController

You can do it in CSS, but there isn't much support in browsers other than modern versions of Chrome, Safari and Opera at the moment. Firefox currently only supports SVG masks. See the Caniuse results for more information.

CSS:

p {
    color: red;
    -webkit-mask-image: -webkit-gradient(linear, left top, left bottom, 
    from(rgba(0,0,0,1)), to(rgba(0,0,0,0)));
}

The trick is to specify a mask that is itself a gradient that ends as invisible (thru alpha value)

See a demo with a solid background, but you can change this to whatever you want.

DEMO

Notice also that all the usual image properties are available for mask-image

p  {_x000D_
  color: red;_x000D_
  font-size: 30px;_x000D_
  -webkit-mask-image: linear-gradient(to left, rgba(0,0,0,1), rgba(0,0,0,0)), linear-gradient(to right, rgba(0,0,0,1), rgba(0,0,0,0));_x000D_
  -webkit-mask-size: 100% 50%;_x000D_
  -webkit-mask-repeat: no-repeat;_x000D_
  -webkit-mask-position: left top, left bottom;_x000D_
  }_x000D_
_x000D_
div {_x000D_
    background-color: lightblue;_x000D_
}

<div><p>text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text text </p></div>

Now, another approach is available, that is supported by Chrome, Firefox, Safari and Opera.

The idea is to use

mix-blend-mode: hard-light;

that gives transparency if the color is gray. Then, a grey overlay on the element creates the transparency

div {_x000D_
  background-color: lightblue;_x000D_
}_x000D_
_x000D_
p {_x000D_
  color: red;_x000D_

  position: relative;_x000D_
  width: 200px;_x000D_
  mix-blend-mode: hard-light;_x000D_
}_x000D_
_x000D_
p::after {_x000D_
  position: absolute;_x000D_
  content: "";_x000D_

  background: linear-gradient(transparent, gray);_x000D_

}

        var q = from b in listOfBoxes
                group b by b.Owner into g
                select new
                           {
                               Owner = g.Key,
                               Boxes = g.Count(),
                               TotalWeight = g.Sum(item => item.Weight),
                               TotalVolume = g.Sum(item => item.Volume)
                           };

I prefer to employ:

from matplotlib import rc
#rc('font',**{'family':'sans-serif','sans-serif':['Helvetica']})
rc('font',**{'family':'serif','serif':['Times']})
rc('text', usetex=True)

Here's a list of the environment variables. I think you might want CURRENT_VARIANT. See also BUILD_VARIANTS.

A simple thing. Disable the vsphere options 3D for the virtual maschine . It works perfect. When you want, reinstall the vm-tools for the virtual maschine.

With : i << 2

const data = context.getImageData(x, y, width, height).data;
const pixels = [];

for (let i = 0, dx = 0; dx < data.length; i++, dx = i << 2) {
    if (data[dx+3] <= 8)
        console.log("transparent x= " + i);
}

There are a number of ways to comment in a batch file

1)Using rem

This is the official way. It apparently takes longer to execute than ::, although it apparently stops parsing early, before the carets are processed. Percent expansion happens before rem and :: are identified, so incorrect percent usage i.e. %~ will cause errors if percents are present. Safe to use anywhere in code blocks.

2)Using labels :, :: or :; etc.

For :: comment, ': comment' is an invalid label name because it begins with an invalid character. It is okay to use a colon in the middle of a label though. If a space begins at the start of label, it is removed : label becomes :label. If a space or a colon appears in the middle of the label, the rest of the name is not interpreted meaning that if there are two labels :f:oo and :f rr, both will be interpreted as :f and only the later defined label in the file will be jumped to. The rest of the label is effectively a comment. There are multiple alternatives to ::, listed here. You can never goto or call a ::foo label. goto :foo and goto ::foo will not work.

They work fine outside of code blocks but after a label in a code block, invalid or not, there has to be a valid command line. :: comment is indeed another valid command. It interprets it as a command and not a label; the command has precedence. Which is the command to cd to the :: volume, which will work if you have executed subst :: C:\, otherwise you get a cannot find the volume error. That's why :; is arguably better because it cannot be interpreted in this way, and therefore is interpreted as a label instead, which serves as the valid command. This is not recursive, i.e, the next label does not need a command after it. That's why they come in twos.

You need to provide a valid command after the label e.g. echo something. A label in a code block has to come with at least one valid command, so the lines come in pairs of two. You will get an unexpected ) error if there is a space or a closing parenthesis on the next line. If there is a space between the two :: lines you will get an invalid syntax error.

You can also use the caret operator in the :: comment like so:

@echo off

echo hello
(
   :;(^
   this^
   is^
   a^
   comment^
   )
   :;
)
   :;^
   this^
   is^
   a^
   comment
   :;
) 

But you need the trailing :; for the reason stated above.

@echo off

(
echo hello
:;
:; comment
:; comment
:;
)
echo hello

It is fine as long as there is an even number. This is undoubtedly the best way to comment -- with 4 lines and :;. With :; you don't get any errors that need to be suppressed using 2> nul or subst :: C:\. You could use subst :: C:\ to make the volume not found error go away but it means you will have to also put C: in the code to prevent your working directory from becoming ::\.

To comment at the end of a line you can do command &:: or command & rem comment, but there still has to be an even number, like so:

@echo off

(
echo hello & :;yes
echo hello & :;yes
:;
)

echo hello

The first echo hello & :;yes has a valid command on the next line but the second & :;yes does not, so it needs one i.e. the :;.

3)Using an invalid environment variable

%= comment =%. In a batch file, environment variables that are not defined are removed from the script. This makes it possible to use them at the end of a line without using &. It is custom to use an invalid environment variable i.e. one that contains an equals sign. The extra equals is not required but makes it look symmetrical. Also, variable names starting with "=" are reserved for undocumented dynamic variables. Those dynamic variables never end with "=", so by using an "=" at both the start and end of the comment, there is no possibility of a name clash. The comment cannot contain % or :.

@echo off 
echo This is an example of an %= Inline Comment =% in the middle of a line.

4)As a command, redirecting stderr to nul

@echo off
(
echo hello
;this is a comment 2> nul
;this is another comment  2> nul
)

5)At the end of a file, everything after an unclosed parenthesis is a comment

@echo off
(
echo hello
)

(this is a comment
this is a comment
this is a comment

Obviously, you'll need a rooted android device. Then set up an FTP server and transfer the files.

Use this:

// RGBA()
function getRandomRGBA() {
    function numbers() {
        var x = Math.floor(Math.random() * 256);
        return x;
    }

    alpha = 1.0;
    return (
        "rgba(" +
        numbers() +
        ", " +
        numbers() +
        ", " +
        numbers() +
        ", " +
        alpha.toFixed(1) +
        ")"
    );
}

Check again. Use debugger if must. My guess is that for some item in userResponseDetails this query finds no elements:

.Where(y => y.ResponseId.Equals(item.ResponseId))

so you can't call

.First()

on it. Maybe try

.FirstOrDefault()

if it solves the issue.

Do NOT return NULL value! This is purely so that you can see and diagnose where problem is. Handle these cases properly.

Try this "one-liner" from Delta's Blog, String To MemoryStream (C#).

MemoryStream stringInMemoryStream =
   new MemoryStream(ASCIIEncoding.Default.GetBytes("Your string here"));

The string will be loaded into the MemoryStream, and you can read from it. See Encoding.GetBytes(...), which has also been implemented for a few other encodings.

I came across your post as I was looking for a solution to the same problem for myself. I put together the following solution using a directive based on a number of posts. You can try it here (try resizing the browser window): http://jsfiddle.net/zbjLh/2/

View:

<div ng-app="miniapp" ng-controller="AppController" ng-style="style()" resize>
    window.height: {{windowHeight}} <br />
    window.width: {{windowWidth}} <br />
</div>

Controller:

var app = angular.module('miniapp', []);

function AppController($scope) {
    /* Logic goes here */
}

app.directive('resize', function ($window) {
    return function (scope, element) {
        var w = angular.element($window);
        scope.getWindowDimensions = function () {
            return { 'h': w.height(), 'w': w.width() };
        };
        scope.$watch(scope.getWindowDimensions, function (newValue, oldValue) {
            scope.windowHeight = newValue.h;
            scope.windowWidth = newValue.w;

            scope.style = function () {
                return { 
                    'height': (newValue.h - 100) + 'px',
                    'width': (newValue.w - 100) + 'px' 
                };
            };

        }, true);

        w.bind('resize', function () {
            scope.$apply();
        });
    }
})

FYI I originally had it working in a controller (http://jsfiddle.net/zbjLh/), but from subsequent reading found that this is uncool from Angular's perspective, so I have now converted it to use a directive.

Importantly, note the true flag at the end of the 'watch' function, for comparing the getWindowDimensions return object's equality (remove or change to false if not using an object).

Settings (Ctrl+Alt+s)--> Apprarance-->Override default fonts by(not recommended):

then change Size to 16+.

var textareas = document.getElementsByTagName('textarea');
var count = textareas.length;
for(var i=0;i<count;i++){
    textareas[i].onkeydown = function(e){
        if(e.keyCode==9 || e.which==9){
            e.preventDefault();
            var s = this.selectionStart;
            this.value = this.value.substring(0,this.selectionStart) + "\t" + this.value.substring(this.selectionEnd);
            this.selectionEnd = s+1; 
        }
    }
}

This solution does not require jQuery and will enable tab functionality on all textareas on a page.

While Ralphs Answer provides an elegant solution, with Spring Security 3.2 you no longer need to implement your own ArgumentResolver.

If you have a UserDetails implementation CustomUser, you can just do this:

@RequestMapping("/messages/inbox")
public ModelAndView findMessagesForUser(@AuthenticationPrincipal CustomUser customUser) {

    // .. find messages for this User and return them...
}

See Spring Security Documentation: @AuthenticationPrincipal

There are two primary ways that pandas makes selections from a DataFrame.

• By Label
• By Integer Location

The documentation uses the term position for referring to integer location. I do not like this terminology as I feel it is confusing. Integer location is more descriptive and is exactly what .iloc stands for. The key word here is INTEGER - you must use integers when selecting by integer location.

Before showing the summary let's all make sure that ...

.ix is deprecated and ambiguous and should never be used

There are three primary indexers for pandas. We have the indexing operator itself (the brackets []), .loc, and .iloc. Let's summarize them:

• [] - Primarily selects subsets of columns, but can select rows as well. Cannot simultaneously select rows and columns.
• .loc - selects subsets of rows and columns by label only
• .iloc - selects subsets of rows and columns by integer location only

I almost never use .at or .iat as they add no additional functionality and with just a small performance increase. I would discourage their use unless you have a very time-sensitive application. Regardless, we have their summary:

• .at selects a single scalar value in the DataFrame by label only
• .iat selects a single scalar value in the DataFrame by integer location only

In addition to selection by label and integer location, boolean selection also known as boolean indexing exists.

Examples explaining .loc, .iloc, boolean selection and .at and .iat are shown below

We will first focus on the differences between .loc and .iloc. Before we talk about the differences, it is important to understand that DataFrames have labels that help identify each column and each row. Let's take a look at a sample DataFrame:

df = pd.DataFrame({'age':[30, 2, 12, 4, 32, 33, 69],
                   'color':['blue', 'green', 'red', 'white', 'gray', 'black', 'red'],
                   'food':['Steak', 'Lamb', 'Mango', 'Apple', 'Cheese', 'Melon', 'Beans'],
                   'height':[165, 70, 120, 80, 180, 172, 150],
                   'score':[4.6, 8.3, 9.0, 3.3, 1.8, 9.5, 2.2],
                   'state':['NY', 'TX', 'FL', 'AL', 'AK', 'TX', 'TX']
                   },
                  index=['Jane', 'Nick', 'Aaron', 'Penelope', 'Dean', 'Christina', 'Cornelia'])

All the words in bold are the labels. The labels, age, color, food, height, score and state are used for the columns. The other labels, Jane, Nick, Aaron, Penelope, Dean, Christina, Cornelia are used as labels for the rows. Collectively, these row labels are known as the index.

The primary ways to select particular rows in a DataFrame are with the .loc and .iloc indexers. Each of these indexers can also be used to simultaneously select columns but it is easier to just focus on rows for now. Also, each of the indexers use a set of brackets that immediately follow their name to make their selections.

.loc selects data only by labels

We will first talk about the .loc indexer which only selects data by the index or column labels. In our sample DataFrame, we have provided meaningful names as values for the index. Many DataFrames will not have any meaningful names and will instead, default to just the integers from 0 to n-1, where n is the length(number of rows) of the DataFrame.

There are many different inputs you can use for .loc three out of them are

• A string
• A list of strings
• Slice notation using strings as the start and stop values

Selecting a single row with .loc with a string

To select a single row of data, place the index label inside of the brackets following .loc.

df.loc['Penelope']

This returns the row of data as a Series

age           4
color     white
food      Apple
height       80
score       3.3
state        AL
Name: Penelope, dtype: object

Selecting multiple rows with .loc with a list of strings

df.loc[['Cornelia', 'Jane', 'Dean']]

This returns a DataFrame with the rows in the order specified in the list:

Selecting multiple rows with .loc with slice notation

Slice notation is defined by a start, stop and step values. When slicing by label, pandas includes the stop value in the return. The following slices from Aaron to Dean, inclusive. Its step size is not explicitly defined but defaulted to 1.

df.loc['Aaron':'Dean']

Complex slices can be taken in the same manner as Python lists.

.iloc selects data only by integer location

Let's now turn to .iloc. Every row and column of data in a DataFrame has an integer location that defines it. This is in addition to the label that is visually displayed in the output. The integer location is simply the number of rows/columns from the top/left beginning at 0.

There are many different inputs you can use for .iloc three out of them are

• An integer
• A list of integers
• Slice notation using integers as the start and stop values

Selecting a single row with .iloc with an integer

df.iloc[4]

This returns the 5th row (integer location 4) as a Series

age           32
color       gray
food      Cheese
height       180
score        1.8
state         AK
Name: Dean, dtype: object

Selecting multiple rows with .iloc with a list of integers

df.iloc[[2, -2]]

This returns a DataFrame of the third and second to last rows:

Selecting multiple rows with .iloc with slice notation

df.iloc[:5:3]

Simultaneous selection of rows and columns with .loc and .iloc

One excellent ability of both .loc/.iloc is their ability to select both rows and columns simultaneously. In the examples above, all the columns were returned from each selection. We can choose columns with the same types of inputs as we do for rows. We simply need to separate the row and column selection with a comma.

For example, we can select rows Jane, and Dean with just the columns height, score and state like this:

df.loc[['Jane', 'Dean'], 'height':]

This uses a list of labels for the rows and slice notation for the columns

We can naturally do similar operations with .iloc using only integers.

df.iloc[[1,4], 2]
Nick      Lamb
Dean    Cheese
Name: food, dtype: object

Simultaneous selection with labels and integer location

.ix was used to make selections simultaneously with labels and integer location which was useful but confusing and ambiguous at times and thankfully it has been deprecated. In the event that you need to make a selection with a mix of labels and integer locations, you will have to make both your selections labels or integer locations.

For instance, if we want to select rows Nick and Cornelia along with columns 2 and 4, we could use .loc by converting the integers to labels with the following:

col_names = df.columns[[2, 4]]
df.loc[['Nick', 'Cornelia'], col_names] 

Or alternatively, convert the index labels to integers with the get_loc index method.

labels = ['Nick', 'Cornelia']
index_ints = [df.index.get_loc(label) for label in labels]
df.iloc[index_ints, [2, 4]]

Boolean Selection

The .loc indexer can also do boolean selection. For instance, if we are interested in finding all the rows where age is above 30 and return just the food and score columns we can do the following:

df.loc[df['age'] > 30, ['food', 'score']] 

You can replicate this with .iloc but you cannot pass it a boolean series. You must convert the boolean Series into a numpy array like this:

df.iloc[(df['age'] > 30).values, [2, 4]] 

Selecting all rows

It is possible to use .loc/.iloc for just column selection. You can select all the rows by using a colon like this:

df.loc[:, 'color':'score':2]

The indexing operator, [], can slice can select rows and columns too but not simultaneously.

Most people are familiar with the primary purpose of the DataFrame indexing operator, which is to select columns. A string selects a single column as a Series and a list of strings selects multiple columns as a DataFrame.

df['food']

Jane          Steak
Nick           Lamb
Aaron         Mango
Penelope      Apple
Dean         Cheese
Christina     Melon
Cornelia      Beans
Name: food, dtype: object

Using a list selects multiple columns

df[['food', 'score']]

What people are less familiar with, is that, when slice notation is used, then selection happens by row labels or by integer location. This is very confusing and something that I almost never use but it does work.

df['Penelope':'Christina'] # slice rows by label

df[2:6:2] # slice rows by integer location

The explicitness of .loc/.iloc for selecting rows is highly preferred. The indexing operator alone is unable to select rows and columns simultaneously.

df[3:5, 'color']
TypeError: unhashable type: 'slice'

Selection by .at and .iat

Selection with .at is nearly identical to .loc but it only selects a single 'cell' in your DataFrame. We usually refer to this cell as a scalar value. To use .at, pass it both a row and column label separated by a comma.

df.at['Christina', 'color']
'black'

Selection with .iat is nearly identical to .iloc but it only selects a single scalar value. You must pass it an integer for both the row and column locations

df.iat[2, 5]
'FL'

Update August 2019

Found the official uninstall docs worked as expected (on Mac OSX).

$ which go
/usr/local/go/bin/go

In summary, to uninstall:

$ sudo rm -rf /usr/local/go
$ sudo rm /etc/paths.d/go

Then, did a fresh install with homebrew using brew install go. Now, i have:

 $ which go

Checkout Xdebbug's var_dump settings, particularly the values of these settings:

xdebug.var_display_max_children
xdebug.var_display_max_data
xdebug.var_display_max_depth

Yes, you can use this query (Instead of 'Specialist' and 'Developer', type any strings you want separated by comma and change employees table with your table)

SELECT * FROM employees em
    WHERE EXISTS (select 1 from table(sys.dbms_debug_vc2coll('Specialist', 'Developer')) mt where em.job like ('%' || mt.column_value || '%'));

Why my query is better than the accepted answer: You don't need a CREATE TABLE permission to run it. This can be executed with just SELECT permissions.

I find this lecture very valuable https://vimeo.com/190275665, in point 3 it summarizes these generators and also gives some performance analysis and guideline one when you use each one.

Just to demonstrate the flexibility of javascript: you can use a oneliner for this

function padLeft(nr, n, str){
    return Array(n-String(nr).length+1).join(str||'0')+nr;
}
//or as a Number prototype method:
Number.prototype.padLeft = function (n,str){
    return Array(n-String(this).length+1).join(str||'0')+this;
}
//examples
console.log(padLeft(23,5));       //=> '00023'
console.log((23).padLeft(5));     //=> '00023'
console.log((23).padLeft(5,' ')); //=> '   23'
console.log(padLeft(23,5,'>>'));  //=> '>>>>>>23'

If you want to use this for negative numbers also:

Number.prototype.padLeft = function (n,str) {
    return (this < 0 ? '-' : '') + 
            Array(n-String(Math.abs(this)).length+1)
             .join(str||'0') + 
           (Math.abs(this));
}
console.log((-23).padLeft(5));     //=> '-00023'

Alternative if you don't want to use Array:

number.prototype.padLeft = function (len,chr) {
 var self = Math.abs(this)+'';
 return (this<0 && '-' || '')+
         (String(Math.pow( 10, (len || 2)-self.length))
           .slice(1).replace(/0/g,chr||'0') + self);
}

You should have a table with the list of emails to check. Then do this query:

SELECT E.Email, CASE WHEN U.Email IS NULL THEN 'Not Exists' ELSE 'Exists' END Status
FROM EmailsToCheck E
LEFT JOIN (SELECT DISTINCT Email FROM Users) U
ON E.Email = U.Email

I had this error message with boot2docker on windows with the docker-oracle-xe-11g image (https://registry.hub.docker.com/u/wnameless/oracle-xe-11g/).

The reason was that the virtual box disk was full (check with boot2docker.exe ssh df). Deleting old images and restarting the container solved the problem.

I might consider using a dict and re.sub for something like this:

import re
repldict = {'zero':'0', 'one':'1' ,'temp':'bob','garage':'nothing'}
def replfunc(match):
    return repldict[match.group(0)]

regex = re.compile('|'.join(re.escape(x) for x in repldict))
with open('file.txt') as fin, open('fout.txt','w') as fout:
    for line in fin:
        fout.write(regex.sub(replfunc,line))

This has a slight advantage to replace in that it is a bit more robust to overlapping matches.

Here's some mapping that could help:

:nnoremap <Leader>q" ciw""<Esc>P
:nnoremap <Leader>q' ciw''<Esc>P
:nnoremap <Leader>qd daW"=substitute(@@,"'\\\|\"","","g")<CR>P

If you haven't changed the mapleader variable, then activate the mapping with \q" \q' or \qd. They add double quote around the word under the cursor, single quote around the word under the cursor, delete any quotes around the word under the cursor respectively.

You no longer need to type in bash.exe path manually. This answer is deprecated. Now you can switch to bash directly, if you have git installed in the default path. If you installed git to a different path you need to use the below solution.

Install Git from https://git-scm.com/download/win.

Then open Visual Studio Code and open the command palette using Ctrl + Shift + P. Then type "open user setting", and then select "Open User Settings" from the drop down menu.

Then this tab will open up with default settings on left and your settings on the right:

Now copy this line of code to your own settings page (the pane on the right hand side) and save - "terminal.integrated.shell.windows": "C:\\Program Files\\Git\\bin\\bash.exe"

Note: "C:\\Program Files\Git\bin\bash.exe" is the path where the bash.exe file is located from the Git installation. If you are using the Windows Subsystem for Linux (WSL) Bash shell, the path would be "C:\Windows\System32\bash.exe"

Now press Ctrl + ` to open up the terminal from Visual Studio Code. And you will have Bash -

FYI, it looks like the syntax for retrieving the values has changed according to:

http://freemarker.sourceforge.net/docs/ref_builtins_hash.html

<#assign h = {"name":"mouse", "price":50}>
<#assign keys = h?keys>
<#list keys as key>${key} = ${h[key]}; </#list>

Shouldn't known_hosts be a flat file, not a directory?

If that's not the problem, then this page on Github might be of some help. Try using SSH with the -v or -vv flag to see verbose error messages. It might give you a better idea of what's failing.

$ rails server -b $IP -p $PORT - that solved the same problem for me

While you should ideally highlight the code which is causing an error and post that within your question, the error is because you are trying to get the inner HTML of the 'status' element:

var idPost=document.getElementById("status").innerHTML;

However the 'status' element does not exist within your HTML - either add the necessary element or change the ID you are trying to locate to point to a valid element.

const querystring=  {};

querystring.stringify = function (obj, sep = '&', eq = '=') {
  const escape = encodeURIComponent;
  const qs = [];
  let key = null;

  for (key in obj) if (obj.hasOwnProperty(key)) {
    qs.push(escape(key) + eq + escape(String(obj[key])));
  }
  return qs.join(sep);
};

Example:

const a  = querystring.stringify({a: 'all of them', b: true});
console.log(a);  // Output: a=all%20of%20them&b=true

With a different example:

Consider this is the string and pattern to be searched for is 'cat':

text = "catmania thiscat thiscatmaina";

Now definitions,

'\b' finds/matches the pattern at the beginning or end of each word.

'\B' does not find/match the pattern at the beginning or end of each word.

Different Cases:

Case 1: At the beginning of each word

result = text.replace(/\bcat/g, "ct");

Now, result is "ctmania thiscat thiscatmaina"

Case 2: At the end of each word

result = text.replace(/cat\b/g, "ct");

Now, result is "catmania thisct thiscatmaina"

Case 3: Not in the beginning

result = text.replace(/\Bcat/g, "ct");

Now, result is "catmania thisct thisctmaina"

Case 4: Not in the end

result = text.replace(/cat\B/g, "ct");

Now, result is "ctmania thiscat thisctmaina"

Case 5: Neither beginning nor end

result = text.replace(/\Bcat\B/g, "ct");

Now, result is "catmania thiscat thisctmaina"

Hope this helps :)

Get set are access modifiers to property. Get reads the property field. Set sets the property value. Get is like Read-only access. Set is like Write-only access. To use the property as read write both get and set must be used.

You may use requests library to find if website is up i.e. status code as 200

import requests
url = "https://www.google.com"
page = requests.get(url)
print (page.status_code) 

>> 200

public mySentences:Array<Object> = [
    {id: 1, text: 'Sentence 1'},
    {id: 2, text: 'Sentence 2'},
    {id: 3, text: 'Sentence 3'},
    {id: 4, text: 'Sentenc4 '},
];

Or rather,

export interface type{
    id:number;
    text:string;
}

public mySentences:type[] = [
    {id: 1, text: 'Sentence 1'},
    {id: 2, text: 'Sentence 2'},
    {id: 3, text: 'Sentence 3'},
    {id: 4, text: 'Sentenc4 '},
];

Only you want to set default value parameter. This calling third overloading method.

dt.Columns.Add("MyRow", type(System.Int32),0);

hit git init using terminal/cmd in your desired folder. It'll do the job.

First we need to find a Button:

Button mButton = (Button) findViewById(R.id.my_button);

After that, you must implement View.OnClickListener and there you should find the TextView and execute the method setText:

mButton.setOnClickListener(new View.OnClickListener {
    public void onClick(View v) {
        final TextView mTextView = (TextView) findViewById(R.id.my_text_view);
        mTextView.setText("Some Text");
    }
});

THIS IS FOR A MAC ONLY!

Here’s what you need to do to make your phone visible to adb:

1. Open terminal (Applications/Utilities/Terminal)
2. cd /System/Library/Extensions/IOUSBFamily.kext/Contents/PlugIns/IOUSBCompositeDriver.kext/Contents
3. sudo nano Info.plist (or vi, or emacs, or whatever console editor you prefer)
4. Copy the IOUSBComposite section (from <key> to </dict>)
5. Paste the section in at line 66 (right after where it appears) so you have 2 copies in the file
6. Change the bDeviceSubClass value from 0 to 2
7. Change the key name from IOUSBComposite to GW620

The end result should look something like this:

                    <key>GW620</key>
                    <dict>
                            <key>CFBundleIdentifier</key>
                            <string>com.apple.driver.AppleUSBComposite</string>
                            <key>IOClass</key>
                            <string>IOUSBCompositeDriver</string>
                            <key>IOProviderClass</key>
                            <string>IOUSBDevice</string>
                            <key>bDeviceClass</key>
                            <integer>0</integer>
                            <key>bDeviceSubClass</key>
                            <integer>2</integer>
                    </dict>

8. sudo diskutil repairpermissions / and let it finish
9. sudo touch /System/Library/Extensions and wait a few mins for the extension reindexing to finish
10. adb devices should now see your phone

Note, this is VERY kludgy, and will probably break every time OSX updates itself, but it works. I can finally stop rebooting every time I want to work on the phone! :D

if x is numeric, then add scale_x_continuous(); if x is character/factor, then add scale_x_discrete(). This might solve your problem.

This could be useful

class func createAttributedStringFrom (string1 : String ,strin2 : String, attributes1 : Dictionary<String, NSObject>, attributes2 : Dictionary<String, NSObject>) -> NSAttributedString{

let fullStringNormal = (string1 + strin2) as NSString
let attributedFullString = NSMutableAttributedString(string: fullStringNormal as String)

attributedFullString.addAttributes(attributes1, range: fullStringNormal.rangeOfString(string1))
attributedFullString.addAttributes(attributes2, range: fullStringNormal.rangeOfString(strin2))
return attributedFullString
}

This gets the timezone code (e.g., GMT) in older javascript (I'm using google app script with old engine):

function getTimezoneName() {
  return new Date().toString().get(/\((.+)\)/);
}

I'm just putting this here in case someone needs it.

Either use a real fully qualified domain name (like dev.yourdomain.com) that pointing to 127.0.0.1 or try editing the proper hosts file (usually /etc/hosts in *nix environments).

I found I could solve this by simply putting the two side by side tables inside of a third table that was centered. Here is the code

I added two lines of code at the top and bottom of the two existing tables
