On Ubuntu 16.04

Here's how I fixed this issue: Refer Docker Compose documentation

1. sudo curl -L https://github.com/docker/compose/releases/download/1.21.0/docker-compose-$(uname -s)-$(uname -m) -o /usr/local/bin/docker-compose

2. sudo chmod +x /usr/local/bin/docker-compose

After you do the curl command , it'll put docker-compose into the

/usr/local/bin

which is not on the PATH. To fix it, create a symbolic link:

3. sudo ln -s /usr/local/bin/docker-compose /usr/bin/docker-compose

And now if you do: docker-compose --version

You'll see that docker-compose is now on the PATH

When hosted in docker containers (linux version for me), you might get a 'Connection Refused' message. In that case you can use IP address 0.0.0.0 which means "all IP addresses on this machine" instead of the localhost loopback to fix the port forwarding.

public class Program
{
    public static void Main(string[] args)
    {
        var host = new WebHostBuilder()
            .UseKestrel()
            .UseContentRoot(Directory.GetCurrentDirectory())
            .UseIISIntegration()
            .UseStartup<Startup>()
            .UseUrls("http://0.0.0.0:5000/")
            .Build();

        host.Run();
    }
}

Open npm command prompt and -- cd solution folder and then just run npm link webpack in NPM cmd prommt and re build..

Override method authenticationManagerBean in WebSecurityConfigurerAdapter to expose the AuthenticationManager built using configure(AuthenticationManagerBuilder) as a Spring bean:

For example:

   @Bean(name = BeanIds.AUTHENTICATION_MANAGER)
   @Override
   public AuthenticationManager authenticationManagerBean() throws Exception {
       return super.authenticationManagerBean();
   }

The error indicates that the DLL is either not a COM DLL or it's corrupt. If it's not a COM DLL and not being used as a COM DLL by an application then there is no need to register it.
From what you say in your question (the service is not registered) it seems that we are talking about a service not correctly installed. I will try to reinstall the application.

It turns out to get this application working under VBScript, I had to do two things.

1. Run RegAsm.exe to register the DLLs.
2. Run the C:\Windows\SysWOW64\cscript.exe to run my VBScript.

If these don't work, check out the other answer here about enabling 32-bit applications in IIS.

The easiest way:

1. Install SQL Server 2016
2. Use STRING_SPLIT https://msdn.microsoft.com/en-us/library/mt684588.aspx

It works even in express edition :).

Here is a little something I cooked up today. Seems to work for me. Basically you override the Add method in your base namespace to do a check and then call the base's Add method in order to actually add it. Hope this works for you

using System;
using System.Collections.Generic;
using System.Collections;

namespace Main
{
    internal partial class Dictionary<TKey, TValue> : System.Collections.Generic.Dictionary<TKey, TValue>
    {
        internal new virtual void Add(TKey key, TValue value)
        {   
            if (!base.ContainsKey(key))
            {
                base.Add(key, value);
            }
        }
    }

    internal partial class List<T> : System.Collections.Generic.List<T>
    {
        internal new virtual void Add(T item)
        {
            if (!base.Contains(item))
            {
                base.Add(item);
            }
        }
    }

    public class Program
    {
        public static void Main()
        {
            Dictionary<int, string> dic = new Dictionary<int, string>();
            dic.Add(1,"b");
            dic.Add(1,"a");
            dic.Add(2,"c");
            dic.Add(1, "b");
            dic.Add(1, "a");
            dic.Add(2, "c");

            string val = "";
            dic.TryGetValue(1, out val);

            Console.WriteLine(val);
            Console.WriteLine(dic.Count.ToString());


            List<string> lst = new List<string>();
            lst.Add("b");
            lst.Add("a");
            lst.Add("c");
            lst.Add("b");
            lst.Add("a");
            lst.Add("c");

            Console.WriteLine(lst[2]);
            Console.WriteLine(lst.Count.ToString());
        }
    }
}

I know there are a lot of answers here already, but none of them helped me. In the end I opened the file /etc/elasticsearch/jvm.options and changed:

-Xms2G
-Xmx2G

to

-Xms256M
-Xmx256M

That solved it for me. Hopefully this helps someone else here.

This is probably the most concise way of achieving your goal.All you need to do is to call Letter.getRandom() and you will get a random enum letter.

public enum Letter {
    A,
    B,
    C,
    //...

    public static Letter getRandom() {
        return values()[(int) (Math.random() * values().length)];
    }
}

While trying to answer this question I found a better tutorial. With it you don't have to compromise the certificate check.

*I did not write this but thanks to Bob Lee for the work

Android does not have a specification to indicate the type of resource string (e.g. text/plain or text/html). There is a workaround, however, that will allow the developer to specify this within the XML file.

1. Define a custom attribute to specify that the android:text attribute is html.
2. Use a subclassed TextView.

Once you define these, you can express yourself with HTML in xml files without ever having to call setText(Html.fromHtml(...)) again. I'm rather surprised that this approach is not part of the API.

This solution works to the degree that the Android studio simulator will display the text as rendered HTML.

res/values/strings.xml (the string resource as HTML)

<resources>
<string name="app_name">TextViewEx</string>
<string name="string_with_html"><![CDATA[
       <em>Hello</em> <strong>World</strong>!
 ]]></string>
</resources>

layout.xml (only the relevant parts)

Declare the custom attribute namespace, and add the android_ex:isHtml attribute. Also use the subclass of TextView.

<RelativeLayout
...
xmlns:android_ex="http://schemas.android.com/apk/res-auto"
...>

<tv.twelvetone.samples.textviewex.TextViewEx
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="@string/string_with_html"
    android_ex:isHtml="true"
    />
 </RelativeLayout>

res/values/attrs.xml (define the custom attributes for the subclass)

 <resources>
<declare-styleable name="TextViewEx">
    <attr name="isHtml" format="boolean"/>
    <attr name="android:text" />
</declare-styleable>
</resources>

TextViewEx.java (the subclass of TextView)

 package tv.twelvetone.samples.textviewex;

 import android.content.Context;
 import android.content.res.TypedArray;
 import android.support.annotation.Nullable;
 import android.text.Html;
 import android.util.AttributeSet;
 import android.widget.TextView;

public TextViewEx(Context context, @Nullable AttributeSet attrs) {
    super(context, attrs);
    TypedArray a = context.obtainStyledAttributes(attrs, R.styleable.TextViewEx, 0, 0);
    try {
        boolean isHtml = a.getBoolean(R.styleable.TextViewEx_isHtml, false);
        if (isHtml) {
            String text = a.getString(R.styleable.TextViewEx_android_text);
            if (text != null) {
                setText(Html.fromHtml(text));
            }
        }
    } catch (Exception e) {
        e.printStackTrace();
    } finally {
        a.recycle();
    }
}
}

This question is very similar to:

Capture console exit C#

Here is how I solved this problem, and dealt with the user hitting the X as well as Ctrl-C. Notice the use of ManualResetEvents. These will cause the main thread to sleep which frees the CPU to process other threads while waiting for either exit, or cleanup. NOTE: It is necessary to set the TerminationCompletedEvent at the end of main. Failure to do so causes unnecessary latency in termination due to the OS timing out while killing the application.

I know, I am late but here is the correct way of doing it. using base64. This technique will convert the array to string.

import base64
import numpy as np
random_array = np.random.randn(32,32)
string_repr = base64.binascii.b2a_base64(random_array).decode("ascii")
array = np.frombuffer(base64.binascii.a2b_base64(string_repr.encode("ascii"))) 

For array to string

Convert binary data to a line of ASCII characters in base64 coding and decode to ASCII to get string repr.

For string to array

First, encode the string in ASCII format then Convert a block of base64 data back to binary and return the binary data.

AWS4-HMAC-SHA256, also known as Signature Version 4, ("V4") is one of two authentication schemes supported by S3.

All regions support V4, but US-Standard¹, and many -- but not all -- other regions, also support the other, older scheme, Signature Version 2 ("V2").

According to http://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-authenticating-requests.html ... new S3 regions deployed after January, 2014 will only support V4.

Since Frankfurt was introduced late in 2014, it does not support V2, which is what this error suggests you are using.

http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingAWSSDK.html explains how to enable V4 in the various SDKs, assuming you are using an SDK that has that capability.

I would speculate that some older versions of the SDKs might not support this option, so if the above doesn't help, you may need a newer release of the SDK you are using.

¹US Standard is the former name for the S3 regional deployment that is based in the us-east-1 region. Since the time this answer was originally written, "Amazon S3 renamed the US Standard Region to the US East (N. Virginia) Region to be consistent with AWS regional naming conventions." For all practical purposes, it's only a change in naming.

This happened to me too. I found that in Eclipse I didn't make a new Java Class file and so that's why it wasn't compiling. Try copying your code into a java class file if it's not already there and then compile.

int RandU(int nMin, int nMax)
{
    return nMin + (int)((double)rand() / (RAND_MAX+1) * (nMax-nMin+1));
}

This is a mapping of 32768 integers to (nMax-nMin+1) integers. The mapping will be quite good if (nMax-nMin+1) is small (as in your requirement). Note however that if (nMax-nMin+1) is large, the mapping won't work (For example - you can't map 32768 values to 30000 values with equal probability). If such ranges are needed - you should use a 32-bit or 64-bit random source, instead of the 15-bit rand(), or ignore rand() results which are out-of-range.

This is possible in case of variable a being accessed by, say 2 web workers through a SharedArrayBuffer as well as some main script. The possibility is low, but it is possible that when the code is compiled to machine code, the web workers update the variable a just in time so the conditions a==1, a==2 and a==3 are satisfied.

This can be an example of race condition in multi-threaded environment provided by web workers and SharedArrayBuffer in JavaScript.

Here is the basic implementation of above:

main.js

// Main Thread

const worker = new Worker('worker.js')
const modifiers = [new Worker('modifier.js'), new Worker('modifier.js')] // Let's use 2 workers
const sab = new SharedArrayBuffer(1)

modifiers.forEach(m => m.postMessage(sab))
worker.postMessage(sab)

worker.js

let array

Object.defineProperty(self, 'a', {
  get() {
    return array[0]
  }
});

addEventListener('message', ({data}) => {
    array = new Uint8Array(data)
    let count = 0
    do {
        var res = a == 1 && a == 2 && a == 3
        ++count
    } while(res == false) // just for clarity. !res is fine
    console.log(`It happened after ${count} iterations`)
    console.log('You should\'ve never seen this')
})

modifier.js

addEventListener('message' , ({data}) => {
    setInterval( () => {
        new Uint8Array(data)[0] = Math.floor(Math.random()*3) + 1
    })
})

On my MacBook Air, it happens after around 10 billion iterations on the first attempt:

Second attempt:

As I said, the chances will be low, but given enough time, it'll hit the condition.

Tip: If it takes too long on your system. Try only a == 1 && a == 2 and change Math.random()*3 to Math.random()*2. Adding more and more to list drops the chance of hitting.

MongoDB has a distinct command which returns an array of distinct values for a field; you can check the length of the array for a count.

There is a shell db.collection.distinct() helper as well:

> db.countries.distinct('country');
[ "Spain", "England", "France", "Australia" ]

> db.countries.distinct('country').length
4

For me the easiest way is to do:

import 'dart:math';
Random rnd = new Random();
r = min + rnd.nextInt(max - min);
//where min and max should be specified.

Thanks to @adam-singer explanation in here.

Here is a robust function that uses both os.remove and shutil.rmtree:

def remove(path):
    """ param <path> could either be relative or absolute. """
    if os.path.isfile(path) or os.path.islink(path):
        os.remove(path)  # remove the file
    elif os.path.isdir(path):
        shutil.rmtree(path)  # remove dir and all contains
    else:
        raise ValueError("file {} is not a file or dir.".format(path))

I used the solution below to export all datagrid values to a text file, rather than using the column names you can use the column index instead.

foreach (DataGridViewRow row in xxxCsvDG.Rows)
{
    File.AppendAllText(csvLocation, row.Cells[0].Value + "," + row.Cells[1].Value + "," + row.Cells[2].Value + "," + row.Cells[3].Value + Environment.NewLine);
}

You can use a much simpler formula. I just created a new workbook to test it.

Column A = Date1 | Column B = Date2 | Column C = Date3

Highlight Column A and enter the conditional formatting formula:

=AND(A1>B1,A1<C1)

You start tomcat from some directory - which is the $cwd for tomcat. You can specify any path relative to this $cwd.

suppose you have

home
- tomcat
 |_bin
- cssStore
 |_file.css

And suppose you start tomcat from ~/tomcat, using the command "bin/startup.sh".

~/tomcat becomes the home directory ($cwd) for tomcat

You can access "../cssStore/file.css" from class files in your servlet now

Hope that helps, - M.S.

Your command does not work because the redirection is performed by your shell which does not have the permission to write to /root/test.out. The redirection of the output is not performed by sudo.

There are multiple solutions:

• Run a shell with sudo and give the command to it by using the -c option:

  sudo sh -c 'ls -hal /root/ > /root/test.out'
  

• Create a script with your commands and run that script with sudo:

  #!/bin/sh
  ls -hal /root/ > /root/test.out
  

  Run sudo ls.sh. See Steve Bennett's answer if you don't want to create a temporary file.

• Launch a shell with sudo -s then run your commands:

  [nobody@so]$ sudo -s
  [root@so]# ls -hal /root/ > /root/test.out
  [root@so]# ^D
  [nobody@so]$
  

• Use sudo tee (if you have to escape a lot when using the -c option):

  sudo ls -hal /root/ | sudo tee /root/test.out > /dev/null
  

  The redirect to /dev/null is needed to stop tee from outputting to the screen. To append instead of overwriting the output file (>>), use tee -a or tee --append (the last one is specific to GNU coreutils).

Thanks go to Jd, Adam J. Forster and Johnathan for the second, third and fourth solutions.

As the others already mentioned: the division operator is / rather than **. If you wanna print the ** character within a string you have to escape it:

print("foo \\")
# will print: foo \

I think to print the string you wanted I think you gonna need this code:

print("Length between sides: " + str((length*length)*2.6) + " \\ 1.5 = " + str(((length*length)*2.6)/1.5) + " Units")

And this one is a more readable version of the above (using the format method):

message = "Length between sides: {0} \\ 1.5 = {1} Units"
val1 = (length * length) * 2.6
val2 = ((length * length) * 2.6) / 1.5
print(message.format(val1, val2))

For VS2015 and VS2017

Works with TFS (on-prem) or VSO (Visual Studio Online - the Azure-hosted offering)

The NuGet documentation provides instructions on how to accomplish this and I just followed them successfully for Visual Studio 2015 & Visual Studio 2017 against VSTS (Azure-hosted TFS). Everything is fully updated as of Nov 2016 Aug 2018.

I recommend you follow NuGet's instructions but just to recap what I did:

1. Make sure your packages folder is not committed to TFS. If it is, get it out of there.
2. Everything else we create below goes into the same folder that your .sln file exists in unless otherwise specified (NuGet's instructions aren't completely clear on this).
3. Create a .nuget folder. You can use Windows Explorer to name it .nuget. for it to successfully save as .nuget (it automatically removes the last period) but directly trying to name it .nuget may not work (you may get an error or it may change the name, depending on your version of Windows). Or name the directory nuget, and open the parent directory in command line prompt. type. ren nuget .nuget
4. Inside of that folder, create a NuGet.config file and add the following contents and save it:

NuGet.config:

<?xml version="1.0" encoding="utf-8"?>
<configuration>
    <solution>
        <add key="disableSourceControlIntegration" value="true" />
    </solution>
</configuration>

5. Go back in your .sln's folder and create a new text file and name it .tfignore (if using Windows Explorer, use the same trick as above and name it .tfignore.)
6. Put the following content into that file:

.tfignore:

# Ignore the NuGet packages folder in the root of the repository.
# If needed, prefix 'packages' with additional folder names if it's 
# not in the same folder as .tfignore.
packages

# include package target files which may be required for msbuild,
# again prefixing the folder name as needed.
!packages/*.targets

7. Save all of this, commit it to TFS, then close & re-open Visual Studio and the Team Explorer should no longer identify the packages folder as a pending check-in.
8. Copy/pasted via Windows Explorer the .tfignore file and .nuget folder to all of my various solutions and committed them and I no longer have the packages folder trying to sneak into my source control repo!

Further Customization

While not mine, I have found this .tfignore template by sirkirby to be handy. The example in my answer covers the Nuget packages folder but this template includes some other things as well as provides additional examples that can be useful if you wish to customize this further.

You can do it by making form and displaying it using ShowDialogBox....

Form.ShowDialog Method - Shows the form as a modal dialog box.

Example:

public void ShowMyDialogBox()
{
   Form2 testDialog = new Form2();

   // Show testDialog as a modal dialog and determine if DialogResult = OK.
   if (testDialog.ShowDialog(this) == DialogResult.OK)
   {
      // Read the contents of testDialog's TextBox.
      this.txtResult.Text = testDialog.TextBox1.Text;
   }
   else
   {
      this.txtResult.Text = "Cancelled";
   }
   testDialog.Dispose();
}

You can use the apache commons library which has a StringUtils class and a join method.

Check this link: https://commons.apache.org/proper/commons-lang/javadocs/api.2.0/org/apache/commons/lang/StringUtils.html

Note that the link above may become obsolete over time, in which case you can just search the web for "apache commons StringUtils", which should allow you to find the latest reference.

(referenced from this thread) Java equivalents of C# String.Format() and String.Join()

Interface can be implemented by any classes and what if that value got changed by one of there implementing class then there will be mislead for other implementing classes. Interface is basically a reference to combine two corelated but different entity.so for that reason the declaring variable inside the interface will implicitly be final and also static because interface can not be instantiate.

Did you try D3.js? Here is a good example.

Yor $.post has no data. You need to pass the form data. You can use serialize() to post the form data. Try this

$("#post-btn").click(function(){
    $.post("process.php", $('#reg-form').serialize() ,function(data){
        alert(data);
    });
});

"SPL-way":

$splArray = SplFixedArray::fromArray($array);
$last_item_with_preserved_index[$splArray->getSize()-1] = $splArray->offsetGet($splArray->getSize()-1);

Read more about SplFixedArray and why it's in some cases ( especially with big-index sizes array-data) more preferable than basic array here => The SplFixedArray class.

I think this should be a simple example:

$('#item1 span').text();

or

$('#item1 span').html();

If all you're really doing is removing the second character, regardless of what it is, you can do this:

s/.//2

but your command is building a mv command and piping it to the shell for execution.

This is no more readable than your version:

find -type f | sed -n 'h;s/.//4;x;s/^/mv /;G;s/\n/ /g;p' | sh

The fourth character is removed because find is prepending each filename with "./".

I'd like to add to the right and successful answers, that if you initialize a view with visibility as View.GONE, the view could have been not initialized and you will get some random errors.

For example if you initialize a layout as View.GONE and then you try to start an animation, from my experience I've got my animation working randomly times. Sometimes yes, sometimes no.

So before handling (resizing, move, whatever) a view, you have to init it as View.VISIBLE or View.INVISIBLE to render it (draw it) in the screen, and then handle it.

 object instanceof Type

is true if the object is a Type or a subclass of Type

 object.getClass().equals(Type.class) 

is true only if the object is a Type

R Studio (and Eclipse + StatET): Highlight the text and use CTRL+SHIFT+C to comment multiple lines in Windows. Or, command+SHIFT+C in OS-X.

What you want to do is to specify the sha1 of the commit you want to restore to. You can get the sha1 by examining the reflog (git reflog) and then doing

git reset --hard <sha1 of desired commit>

But don't wait too long... after a few weeks git will eventually see that commit as unreferenced and delete all the blobs.

You should check Genson. It just works and is much easier to use than most of the existing alternatives in Scala. It is fast, has many features and integrations with some other libs (jodatime, json4s DOM api...).

All that without any fancy unecessary code like implicits, custom readers/writers for basic cases, ilisible API due to operator overload...

Using it is as easy as:

import com.owlike.genson.defaultGenson_

val json = toJson(Person(Some("foo"), 99))
val person = fromJson[Person]("""{"name": "foo", "age": 99}""")

case class Person(name: Option[String], age: Int)

Disclaimer: I am Gensons author, but that doesn't meen I am not objective :)

In My Case, I have a close tab of Home Page. After Re-opening the Jupyter.The Error was automatically gone and We can save the file.

The empty space char would be ' '. If you're looking for null that would be '\0'.

Apache is not running

It could also be something as simple as Apache not being configured to start automatically on boot. Assuming you are on a Red Hat-like system such as CentOS or Fedora, the chkconfig –list command will show you which services are set to start for each runlevel. You should see a line like

    httpd           0:off   1:off   2:on    3:on    4:on    5:on    6:off

If instead it says "off" all the way across, you can activate it with chkconfig httpd on. OR you can start apache manually from your panel.

The following is slower than the approaches timed here, but we can compute the extra column based on the contents of more than one column, and more than two values can be computed for the extra column.

Simple example using just the "Set" column:

def set_color(row):
    if row["Set"] == "Z":
        return "red"
    else:
        return "green"

df = df.assign(color=df.apply(set_color, axis=1))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C  green

Example with more colours and more columns taken into account:

def set_color(row):
    if row["Set"] == "Z":
        return "red"
    elif row["Type"] == "C":
        return "blue"
    else:
        return "green"

df = df.assign(color=df.apply(set_color, axis=1))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C   blue

Edit (21/06/2019): Using plydata

It is also possible to use plydata to do this kind of things (this seems even slower than using assign and apply, though).

from plydata import define, if_else

Simple if_else:

df = define(df, color=if_else('Set=="Z"', '"red"', '"green"'))

print(df)

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B  green
3   Y    C  green

Nested if_else:

df = define(df, color=if_else(
    'Set=="Z"',
    '"red"',
    if_else('Type=="C"', '"green"', '"blue"')))

print(df)                            

  Set Type  color
0   Z    A    red
1   Z    B    red
2   X    B   blue
3   Y    C  green

You can't specify an exact sleep time in Windows. You need a real-time OS for that. The best you can do is specify a minimum sleep time. Then it's up to the scheduler to wake up your thread after that. And never call .Sleep() on the GUI thread.

You can create a directory. using

# create a directory if it doesn't exist
- file: path=/src/www state=directory mode=0755

You can also consult http://docs.ansible.com/ansible/file_module.html for further details regaridng directory and file system.

dataGridView1.SelectedRows[0].Index;

Or if you wanted to use LINQ and get the index of all selected rows, you could do:

dataGridView1.SelectedRows.Select(r => r.Index);

I definitely agree that this is perfect for an extension method, but I think it can be improved a bit.

public static string Remove(this string source, string remove,  int firstN)
    {
        if(firstN <= 0 || string.IsNullOrEmpty(source) || string.IsNullOrEmpty(remove))
        {
            return source;
        }
        int index = source.IndexOf(remove);
        return index < 0 ? source : source.Remove(index, remove.Length).Remove(remove, --firstN);
    }

This does a bit of recursion which is always fun.

Here is a simple unit test as well:

   [TestMethod()]
    public void RemoveTwiceTest()
    {
        string source = "look up look up look it up";
        string remove = "look";
        int firstN = 2;
        string expected = " up  up look it up";
        string actual;
        actual = source.Remove(remove, firstN);
        Assert.AreEqual(expected, actual);

    }

You could change /etc/mongod.conf.

Before

#security:

After

security:
    authorization: "enabled"

Then sudo service mongod restart

This works with my IP camera:

import cv2

#print("Before URL")
cap = cv2.VideoCapture('rtsp://admin:[email protected]/H264?ch=1&subtype=0')
#print("After URL")

while True:

    #print('About to start the Read command')
    ret, frame = cap.read()
    #print('About to show frame of Video.')
    cv2.imshow("Capturing",frame)
    #print('Running..')

    if cv2.waitKey(1) & 0xFF == ord('q'):
        break

cap.release()
cv2.destroyAllWindows()

I found the Stream URL in the Camera's Setup screen:

Note that I added the Username (admin) and Password (123456) of the camera and ended it with an @ symbol before the IP address in the URL (admin:123456@)

This is my first ever post & I'm very inexperienced so please go easy on me, but I feel I've got a valid contribution that may be helpful to someone...

Sometimes you need a very big time window between repeat clicks (eg a mailto link where it takes a couple of secs for the email app to open and you don't want it re-triggered), yet you don't want to slow the user down elsewhere. My solution is to use class names for the links depending on event type, while retaining double-click functionality elsewhere...

var controlspeed = 0;

$(document).on('click','a',function (event) {
    eventtype = this.className;
    controlspeed ++;
    if (eventtype == "eg-class01") {
        speedlimit = 3000;
    } else if (eventtype == "eg-class02") { 
        speedlimit = 500; 
    } else { 
        speedlimit = 0; 
    } 
    setTimeout(function() {
        controlspeed = 0;
    },speedlimit);
    if (controlspeed > 1) {
        event.preventDefault();
        return;
    } else {

        (usual onclick code goes here)

    }
});

Use:

conda create -n py37 -c anaconda anaconda=5.3.1
conda env export -n py37 --file env.yaml

Locate the env.yaml file in C:\Windows\System32 and run the cmd as administrator:

conda env update -n root -f env.yaml

Then it works!

As I didn't find a jQuery-free answer that I could copy/paste, here's the solution I used:

document.getElementById('clickme').onclick = function clickEvent(e) {
      // e = Mouse click event.
      var rect = e.target.getBoundingClientRect();
      var x = e.clientX - rect.left; //x position within the element.
      var y = e.clientY - rect.top;  //y position within the element.
      console.log("Left? : " + x + " ; Top? : " + y + ".");
    }

#clickme {
  margin-top: 20px;
  margin-left: 100px;
  border: 1px solid black;
  cursor: pointer;
}

<div id="clickme">Click Me -<br>
(this box has margin-left: 100px; margin-top: 20px;)</div>

JSFiddle of full example

Just an easy answer for the future which I found easy to use as a starter: Similar to using end='' to avoid a new line, you can use sep='' to avoid the white spaces...for this question here, it would look like this: print('Value is "', value, '"', sep = '')

May it help someone in the future.

I found the solution with this link : http://pixelsvsbytes.com/blog/2013/02/nice-web-fonts-for-every-browser/

Step by step method :

• send your font to a WebFontGenerator and get the zip
• find the TTF font on the Zip file
• then, on linux, do this command (or install by apt-get install ttfautohint):
  ttfautohint --strong-stem-width=g neosansstd-black.ttf neosansstd-black.changed.ttf
• then, one more, send the new TTF file (neosansstd-black.changed.ttf) on the WebFontGenerator
• you get a perfect Zip with all your webfonts !

I hope this will help.

Warning! There's a numbers of errors on the Sun JPA 2 example and the resulting pasted content in Pascal's answer. Please consult this post.

This post and the Sun Java EE 6 JPA 2 example really held back my comprehension of JPA 2. After plowing through the Hibernate and OpenJPA manuals and thinking that I had a good understanding of JPA 2, I still got confused afterwards when returning to this post.

ASCII is in range of 0 to 127, so:

str.replace(/[^\x00-\x7F]/g, "");

File file = new File("path");
OutputStream os = new BufferedOutputStream(new FileOutputStream(file));
bitmap.compress(Bitmap.CompressFormat.JPEG, 100, os);
os.close();

On top of your lastest jsfiddle, you just missed one thing:

#sidebar_wrap {
  width:40%;
  height:200px;
  background:green;
  float:right;
}
#sidebar {
  width:inherit;
  margin-top:10px;
  background-color:limegreen;
  position:fixed;
  max-width: 240px; /*This is you missed*/
}

But, how this will solve your problem? Simple, lets explain why is bigger than expect first.

Fixed element #sidebar will use window width size as base to get its own size, like every other fixed element, once in this element is defined width:inherit and #sidebar_wrap has 40% as value in width, then will calculate window.width * 40%, then when if your window width is bigger than your .container width, #sidebar will be bigger than #sidebar_wrap.

This is way, you must set a max-width in your #sidebar_wrap, to prevent to be bigger than #sidebar_wrap.

Check this jsfiddle that shows a working code and explain better how this works.

1. The query is correct

2A. As far as last seven days have much less rows than whole table an index can help

2B. If you are interested only in Created_Date you can try using some group by and count, it should help with the result set size

Based on @dude answer this should return relevant styles in a object, for instance:

  padding: 0.6em;                                                                                                                                                                            
  background-color: #f7f7f7;

}

This will return:

    var styleSheetsLength = styleSheets.length;
    for(var i = 0; i < styleSheetsLength; i++){
        var classes = styleSheets[i].rules || styleSheets[i].cssRules;
        if (!classes)
            continue;
        var classesLength = classes.length;
        for (var x = 0; x < classesLength; x++) {
            if (classes[x].selectorText == className_) {
                return _.pickBy(classes[x].style, (v, k) => isNaN(parseInt(k)) && typeof(v) == 'string' && v && v != 'initial' && k != 'cssText' )
            }
        }
    }

}

You can do it with a custom view, like this RoundAppBar and RoundBottomAppBar. Here a path is used to clipPath the canvas.

We need to remember that the {% endif %} comes after the {% else %}.

So this is an example:

{% if someTest %}
     <p> Something is True </p>
{% else %}
     <p> Something is False </p>
{% endif %}

What I want is a way to merge my stashed changes with the current changes

Here is another option to do it:

git stash show -p|git apply
git stash drop

git stash show -p will show the patch of last saved stash. git apply will apply it. After the merge is done, merged stash can be dropped with git stash drop.

Won't days * 24 * 60 * 60 * 1000 suffice?

There's a method called getBytes(). Use it wisely .

for this, I have noticed that it far better to show and hide the tags instead of adding and removing them for the DOM. It performs better that way.

I prefer creating a reverse plug-in eg

jQuery.fn.reverse = function(fn) {       
   var i = this.length;

   while(i--) {
       fn.call(this[i], i, this[i])
   }
};

Usage eg:

$('#product-panel > div').reverse(function(i, e) {
    alert(i);
    alert(e);
});

Try Adding this

$('input[name="daterangepicker"]').daterangepicker({

   "locale": {
    "firstDay" :1 // 0 Tuesday - 6 - Monday between
         }});

It must be completed within the locale object of the defined daterangepicker. detailed information can be found here.

I've tried using Flexelint (the unix version of PC-Lint) and had somewhat mixed results. This is likely because I'm working on a very large and knotty code base. I recommend carefully examining each file that is reported as unused.

The main worry is false positives. Multiple includes of the same header are reported as an unneeded header. This is bad since Flexelint does not tell you what line the header is included on or where it was included before.

One of the ways automated tools can get this wrong:

In A.hpp:

class A { 
  // ...
};

In B.hpp:

#include "A.hpp

class B {
    public:
        A foo;
};

In C.cpp:

#include "C.hpp"  

#include "B.hpp"  // <-- Unneeded, but lint reports it as needed
#include "A.hpp"  // <-- Needed, but lint reports it as unneeded

If you blindly follow the messages from Flexelint you'll muck up your #include dependencies. There are more pathological cases, but basically you're going to need to inspect the headers yourself for best results.

I highly recommend this article on Physical Structure and C++ from the blog Games from within. They recommend a comprehensive approach to cleaning up the #include mess:

Guidelines

Here’s a distilled set of guidelines from Lakos’ book that minimize the number of physical dependencies between files. I’ve been using them for years and I’ve always been really happy with the results.

1. Every cpp file includes its own header file first. [snip]
2. A header file must include all the header files necessary to parse it. [snip]
3. A header file should have the bare minimum number of header files necessary to parse it. [snip]

1) For me that's the most simple way passing parameters to async task is like this

// To call the async task do it like this
Boolean[] myTaskParams = { true, true, true };
myAsyncTask = new myAsyncTask ().execute(myTaskParams);

Declare and use the async task like here

private class myAsyncTask extends AsyncTask<Boolean, Void, Void> {

    @Override
    protected Void doInBackground(Boolean...pParams) 
    {
        Boolean param1, param2, param3;

        //

          param1=pParams[0];    
          param2=pParams[1];
          param3=pParams[2];    
      ....
}                           

2) Passing methods to async-task In order to avoid coding the async-Task infrastructure (thread, messagenhandler, ...) multiple times you might consider to pass the methods which should be executed in your async-task as a parameter. Following example outlines this approach. In addition you might have the need to subclass the async-task to pass initialization parameters in the constructor.

 /* Generic Async Task    */
interface MyGenericMethod {
    int execute(String param);
}

protected class testtask extends AsyncTask<MyGenericMethod, Void, Void>
{
    public String mParam;                           // member variable to parameterize the function
    @Override
    protected Void doInBackground(MyGenericMethod... params) {
        //  do something here
        params[0].execute("Myparameter");
        return null;
    }       
}

// to start the asynctask do something like that
public void startAsyncTask()
{
    // 
    AsyncTask<MyGenericMethod, Void, Void>  mytest = new testtask().execute(new MyGenericMethod() {
        public int execute(String param) {
            //body
            return 1;
        }
    });     
}

Using attr() pointing to an external domain may trigger an error like this in Chrome: "Refused to display document because display forbidden by X-Frame-Options". The workaround to this can be to move the whole iframe HTML code into the script (eg. using .html() in jQuery).

Example:

var divMapLoaded = false;
$("#container").scroll(function() {
    if ((!divMapLoaded) && ($("#map").position().left <= $("#map").width())) {
    $("#map-iframe").html("<iframe id=\"map-iframe\" " +
        "width=\"100%\" height=\"100%\" frameborder=\"0\" scrolling=\"no\" " +
        "marginheight=\"0\" marginwidth=\"0\" " +
        "src=\"http://www.google.it/maps?t=m&amp;cid=0x3e589d98063177ab&amp;ie=UTF8&amp;iwloc=A&amp;brcurrent=5,0,1&amp;ll=41.123115,16.853177&amp;spn=0.005617,0.009943&amp;output=embed\"" +
        "></iframe>");
    divMapLoaded = true;
}

For others in my situation, the solution was:

qmake -qt=qt5

This was on Ubuntu 14.04 after install qt5-qmake. qmake was a symlink to qtchooser which takes the -qt argument.

I was in your shoes for a while and finally ended up using node.js, because it can do hybrid solutions like having web and socket server in one. So php backend can submit requests thru http to node web server and then broadcast it with websocket. Very efficiant way to go.

Just small addition to explanation

This structure (function() {})(); is called IIFE (Immediately Invoked Function Expression), it will be executed immediately, when the interpreter will reach this line. So when you're writing these rows:

(function($) {
  // do something
})(jQuery);

this means, that the interpreter will invoke the function immediately, and will pass jQuery as a parameter, which will be used inside the function as $.

You may find useful this implementation: http://www.codeproject.com/Articles/126751/Priority-queue-in-Csharp-with-help-of-heap-data-st.aspx

it is generic and based on heap data structure

Since PercentRelativeLayout was deprecated in 26.0.0 and nested layouts like LinearLayout inside RelativeLayout have a negative impact on performance (Understanding the performance benefits of ConstraintLayout) the best option for you to achieve percentage width is to replace your RelativeLayout with ConstraintLayout.

This can be solved in two ways.

SOLUTION #1 Using guidelines with percentage offset

In both cases, you get something like this

I found several functions defined in http://tw1.php.net/unpack are very useful.
They can covert string to byte array and vice versa.

Take byteStr2byteArray() as an example:

<?php
function byteStr2byteArray($s) {
    return array_slice(unpack("C*", "\0".$s), 1);
}

$msg = "abcdefghijk";
$byte_array = byteStr2byteArray($msg);

for($i=0;$i<count($byte_array);$i++)
{
   printf("0x%02x ", $byte_array[$i]);
}
?>

Add this dependecy in pom.xml file. Hope this help.
In <systemPath> property you have to write your jdk lib path..

    <dependency>  
          <groupId>com.sun</groupId> 
           <artifactId>tools</artifactId>
        <version>1.4.2</version>
        <scope>system</scope>
        <systemPath>C:/Program Files/Java/jdk1.6.0_30/lib/tools.jar</systemPath>
        </dependency> 

They are two different metrics to evaluate your model's performance usually being used in different phases.

Loss is often used in the training process to find the "best" parameter values for your model (e.g. weights in neural network). It is what you try to optimize in the training by updating weights.

Accuracy is more from an applied perspective. Once you find the optimized parameters above, you use this metrics to evaluate how accurate your model's prediction is compared to the true data.

Let us use a toy classification example. You want to predict gender from one's weight and height. You have 3 data, they are as follows:(0 stands for male, 1 stands for female)

y1 = 0, x1_w = 50kg, x2_h = 160cm;

y2 = 0, x2_w = 60kg, x2_h = 170cm;

y3 = 1, x3_w = 55kg, x3_h = 175cm;

You use a simple logistic regression model that is y = 1/(1+exp-(b1*x_w+b2*x_h))

How do you find b1 and b2? you define a loss first and use optimization method to minimize the loss in an iterative way by updating b1 and b2.

In our example, a typical loss for this binary classification problem can be: (a minus sign should be added in front of the summation sign)

We don't know what b1 and b2 should be. Let us make a random guess say b1 = 0.1 and b2 = -0.03. Then what is our loss now?

so the loss is

Then you learning algorithm (e.g. gradient descent) will find a way to update b1 and b2 to decrease the loss.

What if b1=0.1 and b2=-0.03 is the final b1 and b2 (output from gradient descent), what is the accuracy now?

Let's assume if y_hat >= 0.5, we decide our prediction is female(1). otherwise it would be 0. Therefore, our algorithm predict y1 = 1, y2 = 1 and y3 = 1. What is our accuracy? We make wrong prediction on y1 and y2 and make correct one on y3. So now our accuracy is 1/3 = 33.33%

PS: In Amir's answer, back-propagation is said to be an optimization method in NN. I think it would be treated as a way to find gradient for weights in NN. Common optimization method in NN are GradientDescent and Adam.

    private Color FromHex(string hex)
    {
        if (hex.StartsWith("#"))
            hex = hex.Substring(1);

        if (hex.Length != 6) throw new Exception("Color not valid");

        return Color.FromArgb(
            int.Parse(hex.Substring(0, 2), System.Globalization.NumberStyles.HexNumber),
            int.Parse(hex.Substring(2, 2), System.Globalization.NumberStyles.HexNumber),
            int.Parse(hex.Substring(4, 2), System.Globalization.NumberStyles.HexNumber));
    }

There is no such thing as connection on server side and/or browser side. There is only one connection. If one of the sides closes it, then it is closed (and you cannot push data to a connection that is closed obviously).

Now a browser closes the connection when you leave the page (it does not depend on the library/language/OS you are using on the sever-side). This is at least true for WebSockets (it might not be true for long polling because of keep-alive but hopefuly socket.io handles this correctly).

If a problem like this happens, then I'm pretty sure that there's a bug in your own code (on the server side). Possibly you are stacking some event handlers where you should not.

Finds all files in folder and write that data to ArrayList row.

Initialize

ArrayList<ArrayList<String>> row=new ArrayList<ArrayList<String>>();
BufferedReader br=null;

For Accessing row

for(ArrayList<String> data:row){
data.get(col no); 
}
or row.get(0).get(0) // getting first row first col

Functions that reads all files from folders and concatenate them row.

static void readData(){
String path="C:\\Users\\Galaxy Computers\\Desktop\\Java project\\Nasdaq\\";
File files=new File(path);
String[] list=files.list();

try {
        String sCurrentLine;
       char check;
       for(String filename:list){ 
        br = new BufferedReader(new FileReader(path+filename));
        br.readLine();//If file contains uneccessary first line.
        while ((sCurrentLine = br.readLine()) != null) {

           row.add(splitLine(sCurrentLine));
        }
        }
        }

    } catch (IOException e) {
        e.printStackTrace();
    } 
        try {
            if (br != null)br.close();
        } catch (IOException ex) {
            ex.printStackTrace();
        }
    }


   static ArrayList<String> splitLine(String line){
   String[] ar=line.split(",");
   ArrayList<String> d=new ArrayList<String>();
   for(String data:ar){
    d.add(data);
   }

   return d; 
   } 

With re-encoding:

ffmpeg -y -i seeing_noaudio.mp4 -vf "setpts=1.25*PTS" -r 24 seeing.mp4

Without re-encoding:

First step - extract video to raw bitstream

ffmpeg -y -i seeing_noaudio.mp4 -c copy -f h264 seeing_noaudio.h264

Remux with new framerate

ffmpeg -y -r 24 -i seeing_noaudio.h264 -c copy seeing.mp4

This should do it:

Base package

Using the function strftime passing the argument %V to obtain the week of the year as decimal number (01–53) as defined in ISO 8601. (More details in the documentarion: ?strftime)

strftime(c("2014-03-16", "2014-03-17","2014-03-18", "2014-01-01"), format = "%V")

Output:

[1] "11" "12" "12" "01"

For anyone looking for a Xamarin implementation (since events are done differently in C#), I simply created this NavClickHandler class as follows:

public class NavClickHandler : Java.Lang.Object, View.IOnClickListener
{
    private Activity mActivity;
    public NavClickHandler(Activity activity)
    {
        this.mActivity = activity;
    }
    public void OnClick(View v)
    {
        DrawerLayout drawer = (DrawerLayout)mActivity.FindViewById(Resource.Id.drawer_layout);
        if (drawer.IsDrawerOpen(GravityCompat.Start))
        {
            drawer.CloseDrawer(GravityCompat.Start);
        }
        else
        {
            drawer.OpenDrawer(GravityCompat.Start);
        }
    }
}

Then, assigned a custom hamburger menu button like this:

        SupportActionBar.SetDisplayHomeAsUpEnabled(true);
        SupportActionBar.SetDefaultDisplayHomeAsUpEnabled(false);
        this.drawerToggle.DrawerIndicatorEnabled = false;
        this.drawerToggle.SetHomeAsUpIndicator(Resource.Drawable.MenuButton);

And finally, assigned the drawer menu toggler a ToolbarNavigationClickListener of the class type I created earlier:

        this.drawerToggle.ToolbarNavigationClickListener = new NavClickHandler(this);

And then you've got a custom menu button, with click events handled.

Just to let you know:

When you write list1 + list2, you are calling the __add__ method of list1, which returns a new list. in this way you can also deal with myobject + list1 by adding the __add__ method to your personal class.

Each row has an ID. All you have to do is to send this ID to the function setSelected(), store it (in $scope.idSelectedVote for instance), and then check for each row if the selected ID is the same as the current one. Here is a solution (see the documentation for ngClass, if needed):

$scope.idSelectedVote = null;
$scope.setSelected = function (idSelectedVote) {
   $scope.idSelectedVote = idSelectedVote;
};

<ul ng-repeat="vote in votes" ng-click="setSelected(vote.id)" ng-class="{selected: vote.id === idSelectedVote}">
    ...
</ul>

Plunker

It probably depends on the type of collection you are enumerating and the implementation of its indexer. In general though, using foreach is likely to be a better approach.

Also, it'll work with any IEnumerable - not just things with indexers.

If it was working before reinstalling python would solve the issue.

I just hit and resolved this issue using: How can I install a previous version of Python 3 in macOS using homebrew?

If you're using autolayout in iOS 6+, you can do this by adjusting the intrinsicContentSize in a subclass of UILabel.

- (id)initWithFrame:(CGRect)frame
{
    self = [super initWithFrame:frame];
    if (self) {
        self.textAlignment = NSTextAlignmentRight;
    }
    return self;
}

- (CGSize)intrinsicContentSize 
{
    CGSize size = [super intrinsicContentSize];
    return CGSizeMake(size.width + 10.0, size.height);
}

Note that RFC 6266 supersedes the RFCs referenced below. Section 7 outlines some of the related security concerns.

The authority on the content-disposition header is RFC 1806 and RFC 2183. People have also devised content-disposition hacking. It is important to note that the content-disposition header is not part of the HTTP 1.1 standard.

The HTTP 1.1 Standard (RFC 2616) also mentions the possible security side effects of content disposition:

15.5 Content-Disposition Issues

RFC 1806 [35], from which the often implemented Content-Disposition
(see section 19.5.1) header in HTTP is derived, has a number of very
serious security considerations. Content-Disposition is not part of
the HTTP standard, but since it is widely implemented, we are
documenting its use and risks for implementors. See RFC 2183 [49]
(which updates RFC 1806) for details.

If you want to have an affix on your header you can use this tricks, add position: relative on your th and change the position in eventListener('scroll')

I have created an example: https://codesandbox.io/s/rl1jjx0o

I use vue.js but you can use this, without vue.js

The ChildActionOnly attribute ensures that an action method can be called only as a child method from within a view. An action method doesn’t need to have this attribute to be used as a child action, but we tend to use this attribute to prevent the action methods from being invoked as a result of a user request. Having defined an action method, we need to create what will be rendered when the action is invoked. Child actions are typically associated with partial views, although this is not compulsory.

1. [ChildActionOnly] allowing restricted access via code in View

2. State Information implementation for specific page URL. Example: Payment Page URL (paying only once) razor syntax allows to call specific actions conditional

b = a(find(a~=0))

Port 465: IANA has reassigned a new service to this port, and it should no longer be used for SMTP communications.

However, because it was once recognized by IANA as valid, there may be legacy systems that are only capable of using this connection method. Typically, you will use this port only if your application demands it. A quick Google search, and you'll find many consumer ISP articles that suggest port 465 as the recommended setup. Hopefully this ends soon! It is not RFC compliant.

Port 587: This is the default mail submission port. When a mail client or server is submitting an email to be routed by a proper mail server, it should always use this port.

Everyone should consider using this port as default, unless you're explicitly blocked by your upstream network or hosting provider. This port, coupled with TLS encryption, will ensure that email is submitted securely and following the guidelines set out by the IETF.

Port 25: This port continues to be used primarily for SMTP relaying. SMTP relaying is the transmittal of email from email server to email server.

In most cases, modern SMTP clients (Outlook, Mail, Thunderbird, etc) shouldn't use this port. It is traditionally blocked, by residential ISPs and Cloud Hosting Providers, to curb the amount of spam that is relayed from compromised computers or servers. Unless you're specifically managing a mail server, you should have no traffic traversing this port on your computer or server.

I think this covers just about all of the browsers. I have used it successfully in the past.

#div {
    filter: alpha(opacity=50); /* internet explorer */
    -khtml-opacity: 0.5;      /* khtml, old safari */
    -moz-opacity: 0.5;       /* mozilla, netscape */
    opacity: 0.5;           /* fx, safari, opera */
}

To summarize the excellent detailed explanations above, and in the simplest way I can think of, this is due to the limitations of the JVM built-in monitor, which 1) is acquired on the entire synchronization unit (block or object) and 2) does not discriminate about the specific condition being waited/notified on/about.

This means that if multiple threads are waiting on different conditions and notify() is used, the selected thread may not be the one which would make progress on the newly fulfilled condition - causing that thread (and other currently still waiting threads which would be able to fulfill the condition, etc..) not to be able to make progress, and eventually starvation or program hangup.

In contrast, notifyAll() enables all waiting threads to eventually re-acquire the lock and check for their respective condition, thereby eventually allowing progress to be made.

So notify() can be used safely only if any waiting thread is guaranteed to allow progress to be made should it be selected, which in general is satisfied when all threads within the same monitor check for only one and the same condition - a fairly rare case in real world applications.

If the start is always less than the end, we can do:

function range(start, end) {
  var myArray = [];
  for (var i = start; i <= end; i += 1) {
    myArray.push(i);
  }
  return myArray;
};
console.log(range(4, 12));                 // ? [4, 5, 6, 7, 8, 9, 10, 11, 12]

If we want to be able to take a third argument to be able to modify the step used to build the array, and to make it work even though the start is greater than the end:

function otherRange(start, end, step) {
  otherArray = [];
  if (step == undefined) {
    step = 1;
  };
  if (step > 0) {
    for (var i = start; i <= end; i += step) {
      otherArray.push(i);
    }
  } else {
    for (var i = start; i >= end; i += step) {
      otherArray.push(i);
    }
  };
  return otherArray;
};
console.log(otherRange(10, 0, -2));        // ? [10, 8, 6, 4, 2, 0]
console.log(otherRange(10, 15));           // ? [10, 11, 12, 13, 14, 15]
console.log(otherRange(10, 20, 2));        // ? [10, 12, 14, 16, 18, 20]

This way the function accepts positive and negative steps and if no step is given, it defaults to 1.

Annotate type and gender properties with @XmlAttribute and the description property with @XmlValue:

@XmlRootElement
public class Sport {

    protected String type;

    @XmlAttribute
    protected String gender;

    @XmlValue;
    protected String description;

If you still want to take advantage of StyleSheet.create and also have dynamic styles, try this out:

const Circle = ({initial}) => {


const initial = user.pending ? user.email[0] : user.firstName[0];

    const colorStyles = {
        backgroundColor: randomColor()
    };

    return (
        <View style={[styles.circle, colorStyles]}>
            <Text style={styles.text}>{initial.toUpperCase()}</Text>
        </View>
    );
};

const styles = StyleSheet.create({
    circle: {
        height: 40,
        width: 40,
        borderRadius: 30,
        overflow: 'hidden'
    },
    text: {
        fontSize: 12,
        lineHeight: 40,
        color: '#fff',
        textAlign: 'center'
    }
});

Notice how the style property of the View is set as an array that combines your stylesheet with your dynamic styles.

I had this error and it was because there was an update on the server but SourceTree was not showing any updates available (possibly because I was offline when it last checked). So I did a refresh in source tree and now it shows 2 items to push instead of 1 item.

So be sure to press refresh or pull if you get this error and then try again.

• using: You are going to use it.
• namespace: To use what? A namespace.
• std: The std namespace (where features of the C++ Standard Library, such as string or vector, are declared).

After you write this instruction, if the compiler sees string it will know that you may be referring to std::string, and if it sees vector, it will know that you may be referring to std::vector. (Provided that you have included in your compilation unit the header files where they are defined, of course.)

If you don't write it, when the compiler sees string or vector it will not know what you are refering to. You will need to explicitly tell it std::string or std::vector, and if you don't, you will get a compile error.

I ran into a similar problem as well, but where the container I wanted to create needed to mount /var/run/docker.sock as a volume (Portainer Agent), while running it all under a different namespace. Normally a container does not care about which namespace it is started in -- that is sort of the point -- but since access was made from a different namespace, this had to be circumvented.

Adding --userns=host to the run command for the container enabled it to use the attain the correct permissions.

Quite a specific use case, but after more research hours than I want to admit I just thought I should share it with the world if someone else ends up in this situation :)

Simple workaround is to open the file and simply press save button in Excel (no need to change the format). once saved in excel it will start to work and you should be able to see its sheets in the DFT.

Cameron MacFarland nailed it.

I'd like to add that the .NET 4.0 client profile will be included in Windows Update and future Windows releases. Expect most computers to have the client profile, not the full profile. Do not underestimate that fact if you're doing business-to-consumer (B2C) sales.

place a .htaccess file in your root web directory

Whatsoever tweaking you do - if the above is not met - it will not work. Usually its in the System folder, it should be in the root. Cheers!

This can be achieved with ES6 template literals:

<input className={`base-input-class ${class1} ${class2}`}>

XML:

<foo>
   <bar>
      <type foobar="1"/>
      <type foobar="2"/>
   </bar>
</foo>

Python code:

import xml.etree.cElementTree as ET

tree = ET.parse("foo.xml")
root = tree.getroot() 
root_tag = root.tag
print(root_tag) 

for form in root.findall("./bar/type"):
    x=(form.attrib)
    z=list(x)
    for i in z:
        print(x[i])

Output:

foo

I had the same problem, though my project did not use the support library. Adding libs/android-support-v4.jar to the project worked around the problem without needing to revert the build tools back from v19.

If you don't need to pass any arguments an easy workaround is to use valueForKeyPath. This is even possible on a Class object.

NSString *colorName = @"brightPinkColor";
id uicolor = [UIColor class];
if ([uicolor respondsToSelector:NSSelectorFromString(colorName)]){
    UIColor *brightPink = [uicolor valueForKeyPath:colorName];
    ...
}

There is no explicit way to change the favicon globally using CSS that I know of. But you can use a simple trick to change it on the fly.

First just name, or rename, the favicon to "favicon.ico" or something similar that will be easy to remember, or is relevant for the site you're working on. Then add the link to the favicon in the head as you usually would. Then when you drop in a new favicon just make sure it's in the same directory as the old one, and that it has the same name, and there you go!

It's not a very elegant solution, and it requires some effort. But dropping in a new favicon in one place is far easier than doing a find and replace of all the links, or worse, changing them manually. At least this way doesn't involve messing with the code.

Of course dropping in a new favicon with the same name will delete the old one, so make sure to backup the old favicon in case of disaster, or if you ever want to go back to the old design.

Blocking: control returns to invoking precess after processing of primitive(sync or async) completes

Non blocking: control returns to process immediately after invocation

Sorry, but many examples as "improved design" still smell horribly or can be extremely misleading. Having try { } catch { log; throw } is just utterly pointless. Exception logging should be done in central place inside the application. exceptions bubble up the stacktrace anyway, why not log them somewhere up and close to the borders of the system?

Caution should be used when you serialize your context (i.e. DTO in one given example) just into the log message. It can easily contain sensitive information one might not want to reach the hands of all the people who can access the log files. And if you don't add any new information to the exception, I really don't see the point of exception wrapping. Good old Java has some point for that, it requires caller to know what kind of exceptions one should expect then calling the code. Since you don't have this in .NET, wrapping doesn't do any good on at least 80% of the cases I've seen.

First up let me start by saying why we need a database.

We need a database to help organise information in such a manner that we can retrieve that data stored in a efficient manner.

Examples of relational database management systems(SQL):

1)Oracle Database

2)SQLite

3)PostgreSQL

4)MySQL

5)Microsoft SQL Server

6)IBM DB2

Examples of non relational database management systems(NoSQL)

1)MongoDB

2)Cassandra

3)Redis

4)Couchbase

5)HBase

6)DocumentDB

7)Neo4j

Relational databases have normalized data, as in information is stored in tables in forms of rows and columns, and normally when data is in normalized form, it helps to reduce data redundancy, and the data in tables are normally related to each other, so when we want to retrieve the data, we can query the data by using join statements and retrieve data as per our need.This is suited when we want to have more writes, less reads, and not much data involved, also its really easy relatively to update data in tables than in non relational databases. Horizontal scaling not possible, vertical scaling possible to some extent.CAP(Consistency, Availability, Partition Tolerant), and ACID (Atomicity, Consistency, Isolation, Duration)compliance.

Let me show entering data to a relational database using PostgreSQL as an example.

First create a product table as follows:

CREATE TABLE products (
    product_no integer,
    name text,
    price numeric
);

then insert the data

INSERT INTO products (product_no, name, price) VALUES (1, 'Cheese', 9.99);

Let's look at another different example:

Here in a relational database, we can link the student table and subject table using relationships, via foreign key, subject ID, but in a non relational database no need to have two documents, as no relationships, so we store all the subject details and student details in one document say student document, then data is getting duplicated, which makes updating records troublesome.

In non relational databases, there is no fixed schema, data is not normalized. no relationships between data is created, all data mostly put in one document. Well suited when handling lots of data, and can transfer lots of data at once, best where high amounts of reads and less writes, and less updates, bit difficult to query data, as no fixed schema. Horizontal and vertical scaling is possible.CAP (Consistency, Availability, Partition Tolerant)and BASE (Basically Available, soft state, Eventually consistent)compliance.

Let me show an example to enter data to a non relational database using Mongodb

db.users.insertOne({name: ‘Mary’, age: 28 , occupation: ‘writer’ })
db.users.insertOne({name: ‘Ben’ , age: 21})

Hence you can understand that to the database called db, and there is a collections called users, and document called insertOne to which we add data, and there is no fixed schema as our first record has 3 attributes, and second attribute has 2 attributes only, this is no problem in non relational databases, but this cannot be done in relational databases, as relational databases have a fixed schema.

Let's look at another different example

({Studname: ‘Ash’, Subname: ‘Mathematics’, LecturerName: ‘Mr. Oak’})

Hence we can see in non relational database we can enter both student details and subject details into one document, as no relationships defined in non relational databases, but here this way can lead to data duplication, and hence errors in updating can occur therefore.

Hope this explains everything

Also just though I'd post the answer to another related question I had,

a = x ? : y;

Is equivalent to:

a = x ? x : y;

If x is false or null then the value of y is taken.

Well 'Abstract Interface' is a Lexical construct: http://en.wikipedia.org/wiki/Lexical_analysis.

It is required by the compiler, you could also write interface.

Well don't get too much into Lexical construct of the language as they might have put it there to resolve some compilation ambiguity which is termed as special cases during compiling process or for some backward compatibility, try to focus on core Lexical construct.

The essence of `interface is to capture some abstract concept (idea/thought/higher order thinking etc) whose implementation may vary ... that is, there may be multiple implementation.

An Interface is a pure abstract data type that represents the features of the Object it is capturing or representing.

Features can be represented by space or by time. When they are represented by space (memory storage) it means that your concrete class will implement a field and method/methods that will operate on that field or by time which means that the task of implementing the feature is purely computational (requires more cpu clocks for processing) so you have a trade off between space and time for feature implementation.

If your concrete class does not implement all features it again becomes abstract because you have a implementation of your thought or idea or abstractness but it is not complete , you specify it by abstract class.

A concrete class will be a class/set of classes which will fully capture the abstractness you are trying to capture class XYZ.

So the Pattern is

Interface--->Abstract class/Abstract classes(depends)-->Concrete class

If you make

Check the Bit Twiddling Hacks. You need to get the base 2 logarithm, then add 1 to that. Example for a 32-bit value:

Round up to the next highest power of 2

unsigned int v; // compute the next highest power of 2 of 32-bit v

v--;
v |= v >> 1;
v |= v >> 2;
v |= v >> 4;
v |= v >> 8;
v |= v >> 16;
v++;

The extension to other widths should be obvious.

Using the GNU datamash util:

seq 10 | datamash sum 1

Output:

55

If the input data is irregular, with spaces and tabs at odd places, this may confuse datamash, then either use the -W switch:

<commands...> | datamash -W sum 1

...or use tr to clean up the whitespace:

<commands...> | tr -d '[[:blank:]]' | datamash sum 1

If your intention or the context of this question is really garbage collection, then you can set the datasets and datatables to null explicitly or use the keyword using and let them go out of scope. Dispose does not do much as Tetraneutron said it earlier. GC will collect dataset objects that are no longer referenced and also those that are out of scope.

I really wish SO forced people down voting to actually write a comment before downvoting the answer.

you may use this query for selecting top records in oracle. Rakesh B

select * from User_info where id >= (select max(id)-10 from User_info);

Surprised that no one mentioned this yet, but you can simply template on anything 2D supporting [][] semantics.

template <typename TwoD>
void myFunction(TwoD& myArray){
     myArray[x][y] = 5;
     etc...
}

// call with
double anArray[10][10];
myFunction(anArray);

It works with any 2D "array-like" datastructure, such as std::vector<std::vector<T>>, or a user defined type to maximize code reuse.

By using exploits or on badly configured servers it could be possible to download your PHP source. You could however either obfuscate and/or encrypt your code (using Zend Guard, Ioncube or a similar app) if you want to make sure your source will not be readable (to be accurate, obfuscation by itself could be reversed given enough time/resources, but I haven't found an IonCube or Zend Guard decryptor yet...).

Use a Macro.

Macro>Start Recording

Use the keyboard to make your changes in a repeatable manner e.g.

home>type "able">end>down arrow>home

Then go back to the menu and click stop recording then run a macro multiple times.

That should do it and no regex based complications!

One of the alternative solution is to use a container orchestration solution like Kubernetes. Kubernetes has support for init containers which run to completion before other containers can start. You can find an example here with SQL Server 2017 Linux container where API container uses init container to initialise a database

    }
  }

Possible solution:

var tasks = dataList
    .Select(data => Task.Factory.StartNew(arg => DoThreadStuff(data), TaskContinuationOptions.LongRunning | TaskContinuationOptions.PreferFairness))
    .ToArray();

var timeout = TimeSpan.FromMinutes(1);
Task.WaitAll(tasks, timeout);

Assuming dataList is the list of items and each item needs to be processed in a separate thread.

1. Go to /opt/google/chrome.

2. Open google-chrome.

3. Append current home for data directory. Replace this:

exec -a "$0" "$HERE/chrome" "$@"

With this:

exec -a "$0" "$HERE/chrome" "$@" --user-data-dir $HOME

For reference visit site this site, “How to run chrome as root user in Ubuntu.”

Assuming the question is about cleaning the workspace of the current job, you can run:

test -n "$WORKSPACE" && rm -rf "$WORKSPACE"/*

The following approach works for me.

I had same kind of problem in Netbeans.

I updated the image location in the project and when I executed the jsp file, the image was not loaded in the page.

Then I clean and Built the project in Netbeans. Then it worked fine.

Though you need to check the image actually exists or not using the image URL in the browser.

    Use below code it is working to display your key and value here is key start with 1:
         <tr ng-repeat="(key,value) in alert_list" >
                   <td>{{key +1}}</td>
                   <td>{{value.title}}</td>
                 </tr>
Below is document link for it. 

https://docs.angularjs.org/api/ng/directive/ngRepeat

You can pick specific items using destructuring, e.g.:

>>> [first, *middle, last] = range(10)
>>> first
0
>>> middle
[1, 2, 3, 4, 5, 6, 7, 8]
>>> last
9

Note that this is going to consume your generator, so while highly readable, it is less efficient than something like next(), and ruinous on infinite generators:

>>> [first, *rest] = itertools.count()

Exactly what you need:) You can choose callback version or Promise version. Note that promises will work in IE only with Promise polyfill lib.You can put this code once on a page, and this function will appear in all your files.

The loadend event is fired when progress has stopped on the loading of a resource (e.g. after "error", "abort", or "load" have been dispatched)

Callback version

        File.prototype.convertToBase64 = function(callback){
                var reader = new FileReader();
                reader.onloadend = function (e) {
                    callback(e.target.result, e.target.error);
                };   
                reader.readAsDataURL(this);
        };

        $("#asd").on('change',function(){
          var selectedFile = this.files[0];
          selectedFile.convertToBase64(function(base64){
               alert(base64);
          }) 
        });

Promise version

    File.prototype.convertToBase64 = function(){
         return new Promise(function(resolve, reject) {
                var reader = new FileReader();
                reader.onloadend = function (e) {
                    resolve({
                      fileName: this.name,
                      result: e.target.result, 
                      error: e.target.error
                    });
                };   
                reader.readAsDataURL(this);
        }.bind(this));

    FileList.prototype.convertAllToBase64 = function(regexp){
      // empty regexp if not set
      regexp = regexp || /.*/;
      //making array from FileList
      var filesArray = Array.prototype.slice.call(this);
      var base64PromisesArray = filesArray.
           filter(function(file){
             return (regexp).test(file.name)
           }).map(function(file){
             return file.convertToBase64();
           });
      return Promise.all(base64PromisesArray);

With Scanner the default delimiters are the whitespace characters.

But Scanner can define where a token starts and ends based on a set of delimiter, wich could be specified in two ways:

1. Using the Scanner method: useDelimiter(String pattern)
2. Using the Scanner method : useDelimiter(Pattern pattern) where Pattern is a regular expression that specifies the delimiter set.

So useDelimiter() methods are used to tokenize the Scanner input, and behave like StringTokenizer class, take a look at these tutorials for further information:

• Setting Delimiters for Scanner
• Java.util.Scanner.useDelimiter() Method

And here is an Example:

public static void main(String[] args) {

    // Initialize Scanner object
    Scanner scan = new Scanner("Anna Mills/Female/18");
    // initialize the string delimiter
    scan.useDelimiter("/");
    // Printing the tokenized Strings
    while(scan.hasNext()){
        System.out.println(scan.next());
    }
    // closing the scanner stream
    scan.close();
}

Prints this output:

Anna Mills
Female
18

Either the user doesn't have privileges needed to see the table, the table doesn't exist or you are running the query in the wrong schema

Does the table exist?

    select owner, 
           object_name 
    from dba_objects 
    where object_name = any ('CUSTOMER','customer');

What privileges did you grant?

    grant select, insert on customer to user;

Are you running the query against the owner from the first query?

Check here DEMO http://jsfiddle.net/yeyene/Uhm2J/

function getData() {
    $.getJSON('Get/GetData?no=1', function (responseText) {
        //Load some data from the server
    })
};

$(window).scroll(function() {
   if($(window).scrollTop() + $(window).height() == $(document).height()) {
       alert("bottom!");
       // getData();
   }
});

<form name="frmChkForm" id="frmChkForm">
<input type="checkbox" name="chkcc9" id="chkAll">Check Me
<input type="checkbox" name="chk9[120]" class="chkGroup">
<input type="checkbox" name="chk9[140]" class="chkGroup">
<input type="checkbox" name="chk9[150]" class="chkGroup">
</form>

$("#chkAll").click(function() {
   $(".chkGroup").attr("checked", this.checked);
});

With added functionality to ensure the check all checkbox gets checked/dechecked if all individual checkboxes are checked:

$(".chkGroup").click(function() {
  $("#chkAll")[0].checked = $(".chkGroup:checked").length == $(".chkGroup").length;
});

Atomic means only one thread accesses the variable (static type). Atomic is thread-safe, but it is slow.

Nonatomic means multiple threads access the variable (dynamic type). Nonatomic is thread-unsafe, but it is fast.

Much easier way of doing it: you will need com.google.gson.Gson for converting the object to json string for streaming

to convert object to json string for streaming use below code

Gson gson = new Gson();
String jsonString = gson.toJson(MyObject);

To convert back the json string to object use below code:

Gson gson = new Gson();
MyObject = gson.fromJson(decodedString , MyObjectClass.class);

Much easier way to convert object for streaming and read on the other side. Hope this helps. - Vishesh

This is the correct and easiest way to accomplish this for 95% of use cases:

>>> df = pd.DataFrame(zip(*[range(10)]), columns=['num'])
>>> df
    num
0    0
1    1
2    2
3    3
4    4
5    5

>>> def example(x):
...     x['p1'] = x['num']**2
...     x['p2'] = x['num']**3
...     x['p3'] = x['num']**4
...     return x

>>> df = df.apply(example, axis=1)
>>> df
    num  p1  p2  p3
0    0   0   0    0
1    1   1   1    1
2    2   4   8   16
3    3   9  27   81
4    4  16  64  256

The documentation for Platform width() and height(), it's stated that these methods use window.innerWidth and window.innerHeight respectively. But using the methods are preferred since the dimensions are cached values, which reduces the chance of multiple and expensive DOM reads.

import { Platform } from 'ionic-angular';

...
private width:number;
private height:number;

constructor(private platform: Platform){
    platform.ready().then(() => {
        this.width = platform.width();
        this.height = platform.height();
    });
}

ViewParents in general can't remove views, but ViewGroups can. You need to cast your parent to a ViewGroup (if it is a ViewGroup) to accomplish what you want.

For example:

View namebar = View.findViewById(R.id.namebar);
((ViewGroup) namebar.getParent()).removeView(namebar);

Note that all Layouts are ViewGroups.

Try the following:

sudo apt-get install rubygems

The other way to move introduced work from one branch to another is to cherry-pick it. A cherry-pick in Git is like a rebase for a single commit. It takes the patch that was introduced in a commit and tries to reapply it on the branch you’re currently on. This is useful if you have a number of commits on a topic branch and you want to integrate only one of them, or if you only have one commit on a topic branch and you’d prefer to cherry-pick it rather than run rebase. For example, suppose you have a project that looks like this:

If you want to pull commit e43a6 into your master branch, you can run

$ git cherry-pick e43a6
Finished one cherry-pick.
[master]: created a0a41a9: "More friendly message when locking the index fails."
 3 files changed, 17 insertions(+), 3 deletions(-)

This pulls the same change introduced in e43a6, but you get a new commit SHA-1 value, because the date applied is different. Now your history looks like this:

Now you can remove your topic branch and drop the commits you didn’t want to pull in.

Lately, I've been using git reflog to help with this. This mostly only works if the merge JUST happened, and it was on your machine.

git reflog might return something like:

fbb0c0f HEAD@{0}: commit (merge): Merge branch 'master' into my-branch
43b6032 HEAD@{1}: checkout: moving from master to my-branch
e3753a7 HEAD@{2}: rebase finished: returning to refs/heads/master
e3753a7 HEAD@{3}: pull --rebase: checkout e3753a71d92b032034dcb299d2df2edc09b5830e
b41ea52 HEAD@{4}: reset: moving to HEAD^
8400a0f HEAD@{5}: rebase: aborting

The first line indicates that a merge occurred. The 2nd line is the time before my merge. I simply git reset --hard 43b6032 to force this branch to track from before the merge, and carry-on.

Added some more logic to solution provided by @Andrew Burgess. Here is the full solution:

Created a action filter to get errors for ajax request:

public class ValidateAjaxAttribute : ActionFilterAttribute
    {
        public override void OnActionExecuting(ActionExecutingContext filterContext)
        {
            if (!filterContext.HttpContext.Request.IsAjaxRequest())
                return;

            var modelState = filterContext.Controller.ViewData.ModelState;
            if (!modelState.IsValid)
            {
                var errorModel =
                        from x in modelState.Keys
                        where modelState[x].Errors.Count > 0
                        select new
                        {
                            key = x,
                            errors = modelState[x].Errors.
                                                          Select(y => y.ErrorMessage).
                                                          ToArray()
                        };
                filterContext.Result = new JsonResult()
                {
                    Data = errorModel
                };
                filterContext.HttpContext.Response.StatusCode =
                                                      (int)HttpStatusCode.BadRequest;
            }
        }
    }

Added the filter to my controller method as:

[HttpPost]
// this line is important
[ValidateAjax]
public ActionResult AddUpdateData(MyModel model)
{
    return Json(new { status = (result == 1 ? true : false), message = message }, JsonRequestBehavior.AllowGet);
}

Added a common script for jquery validation:

function onAjaxFormError(data) {
    var form = this;
    var errorResponse = data.responseJSON;
    $.each(errorResponse, function (index, value) {
        // Element highlight
        var element = $(form).find('#' + value.key);
        element = element[0];
        highLightError(element, 'input-validation-error');

        // Error message
        var validationMessageElement = $('span[data-valmsg-for="' + value.key + '"]');
        validationMessageElement.removeClass('field-validation-valid');
        validationMessageElement.addClass('field-validation-error');
        validationMessageElement.text(value.errors[0]);
    });
}

$.validator.setDefaults({
            ignore: [],
            highlight: highLightError,
            unhighlight: unhighlightError
        });

var highLightError = function(element, errorClass) {
    element = $(element);
    element.addClass(errorClass);
}

var unhighLightError = function(element, errorClass) {
    element = $(element);
    element.removeClass(errorClass);
}

Finally added the error javascript method to my Ajax Begin form:

@model My.Model.MyModel
@using (Ajax.BeginForm("AddUpdateData", "Home", new AjaxOptions { HttpMethod = "POST", OnFailure="onAjaxFormError" }))
{
}

You don't need to count stuff if you want to pick a random element. Just use random.choice() and pass your iterable:

import random
items = ['foo', 'bar', 'baz']
print random.choice(items)

If you really have to count them, use random.randint(1, count+1).

@TonyO'Hagan is comprehrensive shelljs answer, but, I would like to highlight the synchronous version of his answer:

var shell = require('shelljs');
var output = shell.exec('netstat -rn', {silent:true}).output;
console.log(output);

You say you want to delete any column with the title "Percent Margin of Error" so let's try to make this dynamic instead of naming columns directly.

Sub deleteCol()

On Error Resume Next

Dim wbCurrent As Workbook
Dim wsCurrent As Worksheet
Dim nLastCol, i As Integer

Set wbCurrent = ActiveWorkbook
Set wsCurrent = wbCurrent.ActiveSheet
'This next variable will get the column number of the very last column that has data in it, so we can use it in a loop later
nLastCol = wsCurrent.Cells.Find("*", LookIn:=xlValues, SearchOrder:=xlByColumns, SearchDirection:=xlPrevious).Column

'This loop will go through each column header and delete the column if the header contains "Percent Margin of Error"
For i = nLastCol To 1 Step -1
    If InStr(1, wsCurrent.Cells(1, i).Value, "Percent Margin of Error", vbTextCompare) > 0 Then
        wsCurrent.Columns(i).Delete Shift:=xlShiftToLeft
    End If
Next i

End Sub

With this you won't need to worry about where you data is pasted/imported to, as long as the column headers are in the first row.

EDIT: And if your headers aren't in the first row, it would be a really simple change. In this part of the code: If InStr(1, wsCurrent.Cells(1, i).Value, "Percent Margin of Error", vbTextCompare) change the "1" in Cells(1, i) to whatever row your headers are in.

EDIT 2: Changed the For section of the code to account for completely empty columns.

I like this to have enum in the dayNames. To reduce typing, we can do the following:

#define EP(x) [x] = #x  /* ENUM PRINT */

const char* dayNames[] = { EP(Sunday), EP(Monday)};

sed -e 's/Here\(.*\)String/\1/'

Having /A without additional parameters other than the filename didn't work for me, but the following code worked fine with /n

string sfile = @".\help\delta-pqca-400-100-300-fc4-user-manual.pdf";
Process myProcess = new Process();
myProcess.StartInfo.FileName = "AcroRd32.exe"; 
myProcess.StartInfo.Arguments = " /n " + "\"" + sfile + "\"";
myProcess.Start();

And when you use a case :

CASE
WHEN TB1.COD IS NULL THEN
    TB1.COD || ' - ' || TB1.NAME
ELSE
    TB1.COD || ' - ' || TB1.NAME || ' - ' || TB.NM_TABELAFRETE
END AS NR_FRETE,

I know this is a little old, but is important to notice that React recomends to clear the interval when the component unmounts: https://reactjs.org/docs/state-and-lifecycle.html

So I like to add this answer to this discussion:

  componentDidMount() {
    this.timerID = setInterval(
      () => this.tick(),
      1000
    );
  }
  componentWillUnmount() {
    clearInterval(this.timerID);
  }

One additional tweak worth mentioning: I'm not sure if this is a .NET 4.0 or Visual Studio 2010 feature, but if you're using both you don't need to declare the value parameter for the setter/mutator block of code:

Private _name As String

Public Property Name() As String
    Get
        Return _name
    End Get
    Private Set
        _name = value
    End Set
End Property

The code you posted starts three different processes each with it's own command. To open a command prompt and then run a command try the following (never tried it myself):

try {
    // Execute command
    String command = "cmd /c start cmd.exe";
    Process child = Runtime.getRuntime().exec(command);

    // Get output stream to write from it
    OutputStream out = child.getOutputStream();

    out.write("cd C:/ /r/n".getBytes());
    out.flush();
    out.write("dir /r/n".getBytes());
    out.close();
} catch (IOException e) {
}

For the record: The following snippet can help you to get details about input, textarea, select, button, a tags through a temp title when hover them.

$( 'body' ).on( 'mouseover', 'input, textarea, select, button, a', function() {
    var $tag = $( this );
    var $form = $tag.closest( 'form' );
    var title = this.title;
    var id = this.id;
    var name = this.name;
    var value = this.value;
    var type = this.type;
    var cls = this.className;
    var tagName = this.tagName;
    var options = [];
    var hidden = [];
    var formDetails = '';

    if ( $form.length ) {
        $form.find( ':input[type="hidden"]' ).each( function( index, el ) {
            hidden.push( "\t" + el.name + ' = ' + el.value );
        } );

        var formName = $form.prop( 'name' );
        var formTitle = $form.prop( 'title' );
        var formId = $form.prop( 'id' );
        var formClass = $form.prop( 'class' );

        formDetails +=
            "\n\nFORM NAME: " + formName +
            "\nFORM TITLE: " + formTitle +
            "\nFORM ID: " + formId +
            "\nFORM CLASS: " + formClass +
            "\nFORM HIDDEN INPUT:\n" + hidden.join( "\n" );
    }

    var tempTitle =
        "TAG: " + tagName +
        "\nTITLE: " + title +
        "\nID: " + id +
        "\nCLASS: " + cls;

    if ( 'SELECT' === tagName ) {
        $tag.find( 'option' ).each( function( index, el ) {
            options.push( el.value );
        } );

        tempTitle +=
            "\nNAME: " + name +
            "\nVALUE: " + value +
            "\nTYPE: " + type +
            "\nSELECT OPTIONS:\n\t" + options;

    } else if ( 'A' === tagName ) {
        tempTitle +=
            "\nHTML: " + $tag.html();

    } else {
        tempTitle +=
            "\nNAME: " + name +
            "\nVALUE: " + value +
            "\nTYPE: " + type;
    }

    tempTitle += formDetails;

    $tag.prop( 'title', tempTitle );
    $tag.on( 'mouseout', function() {
        $tag.prop( 'title', title );
    } )
} );

I also had this problem and was able to solve it by enabling CORS support on the server. In my case it was an Azure server and it was easy: Enable CORS on Azure

So check for your server how it works and enable CORS. I didn't even need a browser plugin or proxy :)

In my opinion, directories should not be considered targets of your makefile, either in technical or in design sense. You should create files and if a file creation needs a new directory then quietly create the directory within the rule for the relevant file.

If you're targeting a usual or "patterned" file, just use make's internal variable $(@D), that means "the directory the current target resides in" (cmp. with $@ for the target). For example,

$(OUT_O_DIR)/%.o: %.cpp
        @mkdir -p $(@D)
        @$(CC) -c $< -o $@

title: $(OBJS)

Then, you're effectively doing the same: create directories for all $(OBJS), but you'll do it in a less complicated way.

The same policy (files are targets, directories never are) is used in various applications. For example, git revision control system doesn't store directories.

Note: If you're going to use it, it might be useful to introduce a convenience variable and utilize make's expansion rules.

dir_guard=@mkdir -p $(@D)

$(OUT_O_DIR)/%.o: %.cpp
        $(dir_guard)
        @$(CC) -c $< -o $@

$(OUT_O_DIR_DEBUG)/%.o: %.cpp
        $(dir_guard)
        @$(CC) -g -c $< -o $@

title: $(OBJS)

You need to use a delegated event handler, as the #add elements dynamically appended won't have the click event bound to them. Try this:

$("#buildyourform").on('click', "#add", function() {
    // your code...
});

Also, you can make your HTML strings easier to read by mixing line quotes:

var fieldWrapper = $('<div class="fieldwrapper" name="field' + intId + '" id="field' + intId + '"/>');

Or even supplying the attributes as an object:

var fieldWrapper = $('<div></div>', { 
    'class': 'fieldwrapper',
    'name': 'field' + intId,
    'id': 'field' + intId
});

Don't forget about names like:

• Mathias d'Arras
• Martin Luther King, Jr.
• Hector Sausage-Hausen

This should do the trick for most things:

/^[a-z ,.'-]+$/i

OR Support international names with super sweet unicode:

/^[a-zA-ZàáâäãåacceèéêëeiìíîïlnòóôöõøùúûüuuÿýzzñçcšžÀÁÂÄÃÅACCEEÈÉÊËÌÍÎÏILNÒÓÔÖÕØÙÚÛÜUUŸÝZZÑßÇŒÆCŠŽ?ð ,.'-]+$/u

target_compile_options solution above is wrong, it won't link the library.

Use:

SET(CMAKE_C_FLAGS_RELEASE "${CMAKE_C_FLAGS_RELEASE} -pthread")

OR

target_link_libraries(XXX PUBLIC pthread)

OR

set_target_properties(XXX PROPERTIES LINK_LIBRARIES -pthread)

I'm pretty sure that the join doesn't even do what you want. If there are 100 records in table a with a null qid and 100 records in table b with a null qid, then the join as written should make a cross join and give 10,000 results for those records. If you look at the following code and run the examples, I think that the last one is probably more the result set you intended:

create table #test1 (id int identity, qid int)
create table #test2 (id int identity, qid int)

Insert #test1 (qid)
select null
union all
select null
union all
select 1
union all
select 2
union all
select null

Insert #test2 (qid)
select null
union all
select null
union all
select 1
union all
select 3
union all
select null


select * from #test2 t2
join #test1 t1 on t2.qid = t1.qid

select * from #test2 t2
join #test1 t1 on isnull(t2.qid, 0) = isnull(t1.qid, 0)


select * from #test2 t2
join #test1 t1 on 
 t1.qid = t2.qid OR ( t1.qid IS NULL AND t2.qid IS NULL )


select t2.id, t2.qid, t1.id, t1.qid from #test2 t2
join #test1 t1 on t2.qid = t1.qid
union all
select null, null,id, qid from #test1 where qid is null
union all
select id, qid, null, null from #test2  where qid is null

You need to install Package Control first (from the Python console in Sublime. Visit http://wbond.net/sublime_packages/package_control for more info), and then install emmet from their repository.

First, you should use any WebSocket or polling mechanics to notify the frontend part about changes that happened. I use Flask-SocketIO wrapper, and very happy with async messaging for my tiny apps.

Nest, you can do all logic which you need in a separate thread(s), and notify the frontend via SocketIO object (Flask holds continuous open connection with every frontend client).

As an example, I just implemented page reload on backend file modifications:

<!doctype html>
<script>
    sio = io()

    sio.on('reload',(info)=>{
        console.log(['sio','reload',info])
        document.location.reload()
    })
</script>

class App(Web, Module):

    def __init__(self, V):
        ## flask module instance
        self.flask = flask
        ## wrapped application instance
        self.app = flask.Flask(self.value)
        self.app.config['SECRET_KEY'] = config.SECRET_KEY
        ## `flask-socketio`
        self.sio = SocketIO(self.app)
        self.watchfiles()

    ## inotify reload files after change via `sio(reload)``
    def watchfiles(self):
        from watchdog.observers import Observer
        from watchdog.events import FileSystemEventHandler
        class Handler(FileSystemEventHandler):
            def __init__(self,sio):
                super().__init__()
                self.sio = sio
            def on_modified(self, event):
                print([self.on_modified,self,event])
                self.sio.emit('reload',[event.src_path,event.event_type,event.is_directory])
        self.observer = Observer()
        self.observer.schedule(Handler(self.sio),path='static',recursive=True)
        self.observer.schedule(Handler(self.sio),path='templates',recursive=True)
        self.observer.start()

let obj = { a: 4, b: 0.5 , c: 0.35, d: 5 };

let arr = Object.values(obj);
let min = Math.min(...arr);
let max = Math.max(...arr);

console.log( `Min value: ${min}, max value: ${max}` );

Original Answer:

Try this:

let obj = { a: 4, b: 0.5 , c: 0.35, d: 5 };
var arr = Object.keys( obj ).map(function ( key ) { return obj[key]; });

and then:

var min = Math.min.apply( null, arr );
var max = Math.max.apply( null, arr );

You can use fingerprintjs2

new Fingerprint2().get(function(result, components) {
  console.log(result) // a hash, representing your device fingerprint
  console.log(components) // an array of FP components
  //submit hash and JSON object to the server 
})

After that you can check all your users against existing and check JSON similarity, so even if their fingerprint mutates, you still can track them

You should always include all relevant code when asking a question. In this case, the print statement that is the center of your question. The print statement is probably the most crucial piece of information. The second most crucial piece of information is the error, which you also did not include. Next time, include both of those.

print $ids should be a fairly hard statement to mess up, but it is possible. Possible reasons:

1. $ids is undefined. Gives the warning undefined value in print
2. $ids is out of scope. With use strict, gives fatal warning Global variable $ids needs explicit package name, and otherwise the undefined warning from above.
3. You forgot a semi-colon at the end of the line.
4. You tried to do print $ids $nIds, in which case perl thinks that $ids is supposed to be a filehandle, and you get an error such as print to unopened filehandle.

Explanations

1: Should not happen. It might happen if you do something like this (assuming you are not using strict):

my $var;
while (<>) {
    $Var .= $_;
}
print $var;

Gives the warning for undefined value, because $Var and $var are two different variables.

2: Might happen, if you do something like this:

if ($something) {
    my $var = "something happened!";
}
print $var;

my declares the variable inside the current block. Outside the block, it is out of scope.

3: Simple enough, common mistake, easily fixed. Easier to spot with use warnings.

4: Also a common mistake. There are a number of ways to correctly print two variables in the same print statement:

print "$var1 $var2";  # concatenation inside a double quoted string
print $var1 . $var2;  # concatenation
print $var1, $var2;   # supplying print with a list of args

Lastly, some perl magic tips for you:

use strict;
use warnings;

# open with explicit direction '<', check the return value
# to make sure open succeeded. Using a lexical filehandle.
open my $fh, '<', 'file.txt' or die $!;

# read the whole file into an array and
# chomp all the lines at once
chomp(my @file = <$fh>);
close $fh;

my $ids  = join(' ', @file);
my $nIds = scalar @file;
print "Number of lines: $nIds\n";
print "Text:\n$ids\n";

Reading the whole file into an array is suitable for small files only, otherwise it uses a lot of memory. Usually, line-by-line is preferred.

Variations:

• print "@file" is equivalent to $ids = join(' ',@file); print $ids;
• $#file will return the last index in @file. Since arrays usually start at 0, $#file + 1 is equivalent to scalar @file.

You can also do:

my $ids;
do {
    local $/;
    $ids = <$fh>;
}

By temporarily "turning off" $/, the input record separator, i.e. newline, you will make <$fh> return the entire file. What <$fh> really does is read until it finds $/, then return that string. Note that this will preserve the newlines in $ids.

Line-by-line solution:

open my $fh, '<', 'file.txt' or die $!; # btw, $! contains the most recent error
my $ids;
while (<$fh>) {
    chomp;
    $ids .= "$_ "; # concatenate with string
}
my $nIds = $.; # $. is Current line number for the last filehandle accessed.

Though insertBefore() (see MDN) is great and referenced by most answers here. For added flexibility, and to be a little more explicit, you can use:

insertAdjacentElement() (see MDN) This lets you reference any element, and insert the to-be moved element exactly where you want:

<!-- refElem.insertAdjacentElement('beforebegin', moveMeElem); -->
<p id="refElem">
    <!-- refElem.insertAdjacentElement('afterbegin', moveMeElem); -->
    ... content ...
    <!-- refElem.insertAdjacentElement('beforeend', moveMeElem); -->
</p>
<!-- refElem.insertAdjacentElement('afterend', moveMeElem); -->

Others to consider for similar use cases: insertAdjacentHTML() and insertAdjacentText()

This is something I just recently had to do:

set ANSI_NULLS ON
set QUOTED_IDENTIFIER ON
GO
ALTER PROCEDURE [dbo].[cjso_UpdateCustomerLogin]
    (
      @CustomerID AS INT,
      @UserName AS VARCHAR(25),
      @Password AS BINARY(16)
    )
AS 
    BEGIN
        IF ISNULL((SELECT CustomerID FROM tblOnline_CustomerAccount WHERE CustomerID = @CustomerID), 0) = 0
        BEGIN
            INSERT INTO [tblOnline_CustomerAccount] (
                [CustomerID],
                [UserName],
                [Password],
                [LastLogin]
            ) VALUES ( 
                /* CustomerID - int */ @CustomerID,
                /* UserName - varchar(25) */ @UserName,
                /* Password - binary(16) */ @Password,
                /* LastLogin - datetime */ NULL ) 
        END
        ELSE
        BEGIN
            UPDATE  [tblOnline_CustomerAccount]
            SET     UserName = @UserName,
                    Password = @Password
            WHERE   CustomerID = @CustomerID    
        END

    END

If you want to apply the WHERE clause to the result of the UNION, then you have to embed the UNION in the FROM clause:

SELECT *
  FROM (SELECT * FROM TableA
        UNION
        SELECT * FROM TableB
       ) AS U
 WHERE U.Col1 = ...

I'm assuming TableA and TableB are union-compatible. You could also apply a WHERE clause to each of the individual SELECT statements in the UNION, of course.

The problem is that [...] in python has two distinct meanings

1. expr [ index ] means accessing an element of a list
2. [ expr1, expr2, expr3 ] means building a list of three elements from three expressions

In your code you forgot the comma between the expressions for the items in the outer list:

[ [a, b, c] [d, e, f] [g, h, i] ]

therefore Python interpreted the start of second element as an index to be applied to the first and this is what the error message is saying.

The correct syntax for what you're looking for is

[ [a, b, c], [d, e, f], [g, h, i] ]

One way to center any element of unknown height and width both horizontally and vertically:

table {
    position: absolute;
    top: 50%;
    left: 50%;
    transform: translate(-50%, -50%);
}

See Example

Alternatively, use a flex container:

.parent-element {
    display: flex;
    justify-content: center;
    align-items: center;
}

The funny symbols you're encountering are a UTF-8 BOM (Byte Order Mark). To get rid of them, open the file using the correct encoding (I'm assuming you're on Python 3):

file = open(r"D:\zzzz\names2.txt", "r", encoding="utf-8-sig")

Furthermore, for counting, you can use collections.Counter:

from collections import Counter
wordcount = Counter(file.read().split())

Display them with:

>>> for item in wordcount.items(): print("{}\t{}".format(*item))
...
snake   1
lion    2
goat    2
horse   3

Your example creates multiple key: value pairs if using fromkeys. If you don't want this, you can use one key and create an alias for the key. For example if you are using a register map, your key can be the register address and the alias can be register name. That way you can perform read/write operations on the correct register.

>>> mydict = {}
>>> mydict[(1,2)] = [30, 20]
>>> alias1 = (1,2)
>>> print mydict[alias1]
[30, 20]
>>> mydict[(1,3)] = [30, 30]
>>> print mydict
{(1, 2): [30, 20], (1, 3): [30, 30]}
>>> alias1 in mydict
True

Try this to avoid all the annoying dialog boxes appearing while you work when trying to simulate the click on the toolbar connect button every minute. you can just copy paste this to your console, call the method and you can work on your notebook.

function connectRefresher() {
       window.ConnectButtonIntervalId = setInterval(function ConnectButton(){
                console.log("connected"); 
                document.querySelector("#top-toolbar > colab-connect-button").shadowRoot.querySelector("#connect").click();
                document.querySelector("colab-sessions-dialog").shadowRoot.querySelector("#footer > div > paper-button").click();
                console.log("closed the dialog!!"); 
            },60000);
    }
    
function clearRefresher() { 
           console.log("clear Interval called !!");
           clearInterval(window.ConnectButtonIntervalId);
    }

 connectRefresher(); //to connect the refresher
 clearRefresher(); //to disconnect the refresher

In version 7.1.2 pip downloads the wheel of a package (if available) with the following:

pip install package -d /path/to/downloaded/file

The following downloads a source distribution:

pip install package -d /path/to/downloaded/file --no-binary :all:

These download the dependencies as well, if pip is aware of them (e.g., if pip show package lists them).

Update

As noted by Anton Khodak, pip download command is preferred since version 8. In the above examples this means that /path/to/downloaded/file needs to be given with option -d, so replacing install with download works.

The advantage of lists appears if you need to insert items in the middle and don't want to start resizing the array and shifting things around.

You're correct in that this is typically not the case. I've had a few very specific cases like that, but not too many.

This happens because the scipy module doesn't have any attribute named sparse. That attribute only gets defined when you import scipy.sparse.

Submodules don't automatically get imported when you just import scipy; you need to import them explicitly. The same holds for most packages, although a package can choose to import its own submodules if it wants to. (For example, if scipy/__init__.py included a statement import scipy.sparse, then the sparse submodule would be imported whenever you import scipy.)

JavaScript doesn't have a built-in init() function, that is, it's not a part of the language. But it's not uncommon (in a lot of languages) for individual programmers to create their own init() function for initialisation stuff.

A particular init() function may be used to initialise the whole webpage, in which case it would probably be called from document.ready or onload processing, or it may be to initialise a particular type of object, or...well, you name it.

What any given init() does specifically is really up to whatever the person who wrote it needed it to do. Some types of code don't need any initialisation.

function init() {
  // initialisation stuff here
}

// elsewhere in code
init();

callback from adapter to activity can be done using registering listener in form of interface: Make an interface:

      public MyInterface{
         public void  yourmethod(//incase needs parameters );
         }

In Adapter Let's Say MyAdapter:

    public MyAdapter extends BaseAdapter{
       private MyInterface listener;

    MyAdapter(Context context){
        try {
            this. listener = (( MyInterface ) context);
              } catch (ClassCastException e) {
               throw new ClassCastException("Activity must implement MyInterface");
          }

//do this where u need to fire listener l

          try {
                listener . yourmethod ();
            } catch (ClassCastException exception) {
               // do something
            }

      In Activity Implement your method:


         MyActivity extends AppCompatActivity implements MyInterface{

                yourmethod(){
                //do whatever you want
                     }
                     }

Simple input[name=Sex][value=M] would do pretty nice. And it's actually well-described in the standard doc:

Multiple attribute selectors can be used to refer to several attributes of an element, or even several times to the same attribute.

Here, the selector matches all SPAN elements whose "hello" attribute has exactly the value "Cleveland" and whose "goodbye" attribute has exactly the value "Columbus":

span[hello="Cleveland"][goodbye="Columbus"] { color: blue; }

As a side note, using quotation marks around an attribute value is required only if this value is not a valid identifier.

JSFiddle Demo

I use jQuery prop

$('#yourCheckbox').change(function(){
  if($(this).prop("checked")) {
    $('#showDiv').show();
  } else {
    $('#hideDiv').hide();
  }
});

It gets serialized so that the URI can read the name value pairs in the POST request by default. You could try setting processData:false to your list of params. Not sure if that would help.

I had to close and re-open my windows console (or open a new console), and then open the SDK manager (ran android), after which a bunch of updates and installs had to complete.

Do Following steps:

1. Start Android Studio.
2. Close any open project.Go to File > Close Project.(Welcome window will open)
3. Go to Configure > Settings.
4. On Settings dialog,select Compiler (Gradle-based Android Projects) from left and set VM Options to -Xmx512m(i.e. write -Xmx512m under VM Options:) and press OK.

Try this query.. It uses the Analytic function SUM:

SELECT * FROM
(  
 SELECT SUM(1) OVER(PARTITION BY ctn_no) cnt, A.*
 FROM table1 a 
 WHERE s_ind ='Y'   
)
WHERE cnt > 2

Am not sure why you are identifying a record as a duplicate if the ctn_no repeats more than 2 times. FOr me it repeats more than once it is a duplicate. In this case change the las part of the query to WHERE cnt > 1

What you want cannot be done, because plt.legend() places a legend in the current axes, in your case in the last one.

If, on the other hand, you can be content with placing a comprehensive legend in the last subplot, you can do like this

f, (ax1, ax2, ax3) = plt.subplots(3, sharex=True, sharey=True)
l1,=ax1.plot(x,y, color='r', label='Blue stars')
l2,=ax2.plot(x,y, color='g')
l3,=ax3.plot(x,y, color='b')
ax1.set_title('2012/09/15')
plt.legend([l1, l2, l3],["HHZ 1", "HHN", "HHE"])
plt.show()

Note that you pass to legend not the axes, as in your example code, but the lines as returned by the plot invocation.

PS

Of course you can invoke legend after each subplot, but in my understanding you already knew that and were searching for a method for doing it at once.
