newaxis object in the selection tuple serves to expand the dimensions of the resulting selection by one unit-length dimension.

It is not just conversion of row matrix to column matrix.

Consider the example below:

In [1]:x1 = np.arange(1,10).reshape(3,3)
       print(x1)
Out[1]: array([[1, 2, 3],
               [4, 5, 6],
               [7, 8, 9]])

Now lets add new dimension to our data,

In [2]:x1_new = x1[:,np.newaxis]
       print(x1_new)
Out[2]:array([[[1, 2, 3]],

              [[4, 5, 6]],

              [[7, 8, 9]]])

You can see that newaxis added the extra dimension here, x1 had dimension (3,3) and X1_new has dimension (3,1,3).

How our new dimension enables us to different operations:

In [3]:x2 = np.arange(11,20).reshape(3,3)
       print(x2)
Out[3]:array([[11, 12, 13],
              [14, 15, 16],
              [17, 18, 19]]) 

Adding x1_new and x2, we get:

In [4]:x1_new+x2
Out[4]:array([[[12, 14, 16],
               [15, 17, 19],
               [18, 20, 22]],

              [[15, 17, 19],
               [18, 20, 22],
               [21, 23, 25]],

              [[18, 20, 22],
               [21, 23, 25],
               [24, 26, 28]]])

Thus, newaxis is not just conversion of row to column matrix. It increases the dimension of matrix, thus enabling us to do more operations on it.

I ran into this a couple times a quarter. This time I had a minimal change summary in my git diff and tracked the problem to a reset classpath (missing my WEB-INF/lib dependency) in eclipse. This seems to occur any time I pull in or pull out parent/sibling maven projects.

There are mentions of adding your spring jars to the tomcat web container lib - this is ok and is the way most EE servers run. However be aware that by placing spring higher in the classloader tree on tomcat you will be running higher than the classloader level of your war context. I recommend you leave the libs in a per/war lower level classloader.

We see the following after a truncated .classpath after a structural project change in eclipse.

Dec 18, 2016 11:13:39 PM org.apache.catalina.core.StandardContext listenerStart
SEVERE: Error configuring application listener of class org.springframework.web.context.request.RequestContextListener
java.lang.ClassNotFoundException: org.springframework.web.context.request.RequestContextListener

My classpath was reset and the WEB-INF/lib dependency was removed.

<classpathentry kind="con" path="org.eclipse.m2e.MAVEN2_CLASSPATH_CONTAINER">
    <attributes>
        <attribute name="maven.pomderived" value="true"/>
        <attribute name="org.eclipse.jst.component.dependency" value="/WEB-INF/lib"/>

put back

and you will be OK.

In Angular 5.12 and latest Angular CLI, do

ng generate service my-service -m app.module

You can do:Math.round(<double precision value> * 100.0) / 100.0 But Math.round is fastest but it breaks down badly in corner cases with either a very high number of decimal places (e.g. round(1000.0d, 17)) or large integer part (e.g. round(90080070060.1d, 9)).

Use Bigdecimal it is bit inefficient as it converts the values to string but more relieval: BigDecimal(<value>).setScale(<places>, RoundingMode.HALF_UP).doubleValue() use your preference of Rounding mode.

If you are curious and want to know more detail why this happens you can read this:

Just a brief addition; if you want to install a specific version on MacOS using Homebrew 1.5.2, you can install it the following way:

1. brew update
2. brew search maven

This will give you maven versions available in homebrew

3. brew install [email protected]

[If you want to install maven 3.3.]

A good way is to create a procedure:

create proc pagination (@startfrom int ,@endto int) as
SELECT * FROM ( 
  SELECT *, ROW_NUMBER() OVER (ORDER BY name desc) as row FROM sys.databases 
 ) a WHERE a.row > @startfrom and a.row <= @endto

just like limit 0,2 /////////////// execute pagination 0,4

CSS code:

.hide{
display:none;
}

.show{
display:block;
}

Html code:

<button onclick="block_none()">Check Availability</button>

Javascript Code:

function block_none(){
 document.getElementById('hidden-div').classList.add('show');
document.getElementById('button-id').classList.add('hide');
}

Yes, you can store images in the database, but it's not advisable in my opinion, and it's not general practice.

A general practice is to store images in directories on the file system and store references to the images in the database. e.g. path to the image,the image name, etc.. Or alternatively, you may even store images on a content delivery network (CDN) or numerous hosts across some great expanse of physical territory, and store references to access those resources in the database.

Images can get quite large, greater than 1MB. And so storing images in a database can potentially put unnecessary load on your database and the network between your database and your web server if they're on different hosts.

I've worked at startups, mid-size companies and large technology companies with 400K+ employees. In my 13 years of professional experience, I've never seen anyone store images in a database. I say this to support the statement it is an uncommon practice.

It seems to me you are using the wrong version...

TAP-Win32 should not be installed on the 64bit version. Download the right one and try again!

Python can use all memory available to its environment. My simple "memory test" crashes on ActiveState Python 2.6 after using about

1959167 [MiB]

On jython 2.5 it crashes earlier:

 239000 [MiB]

probably I can configure Jython to use more memory (it uses limits from JVM)

Test app:

import sys

sl = []
i = 0
# some magic 1024 - overhead of string object
fill_size = 1024
if sys.version.startswith('2.7'):
    fill_size = 1003
if sys.version.startswith('3'):
    fill_size = 497
print(fill_size)
MiB = 0
while True:
    s = str(i).zfill(fill_size)
    sl.append(s)
    if i == 0:
        try:
            sys.stderr.write('size of one string %d\n' % (sys.getsizeof(s)))
        except AttributeError:
            pass
    i += 1
    if i % 1024 == 0:
        MiB += 1
        if MiB % 25 == 0:
            sys.stderr.write('%d [MiB]\n' % (MiB))

In your app you read whole file at once. For such big files you should read the line by line.

Often, you will want a fast install from local archives, without probing PyPI.

First, download the archives that fulfill your requirements:

$ pip install --download <DIR> -r requirements.txt

Then, install using –find-links and –no-index:

$ pip install --no-index --find-links=[file://]<DIR> -r requirements.txt

doctormad's solution is not correct. try this:

$var = '1a';
if ((int) $var == $var) {
    var_dump("$var is an integer, really?");
}

this prints

1a is an integer, really?"

use filter_var() with FILTER_VALIDATE_INT argument

$data = Array('0', '1', '1a', '1.1', '1e', '0x24', PHP_INT_MAX+1);
array_walk($data, function ($num){
$is_int = filter_var($num, FILTER_VALIDATE_INT);
if ($is_int === false)
var_dump("$num is not int");
});

this prints

1a is not int 
1.1 is not int
1e is not int
0x24 is not int
9.2233720368548E+18 is not int

Simple solution, make a custom control. (this is made in Xamarin android but should port easily to java)

public class EditTextDecimalNumber:EditText
{
    readonly string _numberFormatDecimalSeparator;

    public EditTextDecimalNumber(Context context, IAttributeSet attrs) : base(context, attrs)
    {
        InputType = InputTypes.NumberFlagDecimal;
        TextChanged += EditTextDecimalNumber_TextChanged;
        _numberFormatDecimalSeparator = System.Threading.Thread.CurrentThread.CurrentUICulture.NumberFormat.NumberDecimalSeparator;

        KeyListener = DigitsKeyListener.GetInstance($"0123456789{_numberFormatDecimalSeparator}");
    }

    private void EditTextDecimalNumber_TextChanged(object sender, TextChangedEventArgs e)
    {
        int noOfOccurence = this.Text.Count(x => x.ToString() == _numberFormatDecimalSeparator);
        if (noOfOccurence >=2)
        {
            int lastIndexOf = this.Text.LastIndexOf(_numberFormatDecimalSeparator,StringComparison.CurrentCulture);
            if (lastIndexOf!=-1)
            {
                this.Text = this.Text.Substring(0, lastIndexOf);
                this.SetSelection(this.Text.Length);
            }

        }
    }
}

As per the documentation on the return statement, return may only occur syntactically nested in a function definition. The same is true for yield.

If you created ImageView from Java Class

ImageView img = new ImageView(this);

//Here we are setting the image in image view
img.setImageResource(R.drawable.my_image);

The other answers are entirely correct, but this answer provides some extra detalis, I think.

Consider this example:

using System;

static class Program {
  static void Main() {
    try {
      ThrowTest();
    } catch (Exception e) {
      Console.WriteLine("Your stack trace:");
      Console.WriteLine(e.StackTrace);
      Console.WriteLine();
      if (e.InnerException == null) {
        Console.WriteLine("No inner exception.");
      } else {
        Console.WriteLine("Stack trace of your inner exception:");
        Console.WriteLine(e.InnerException.StackTrace);
      }
    }
  }

  static void ThrowTest() {
    decimal a = 1m;
    decimal b = 0m;
    try {
      Mult(a, b);  // line 34
      Div(a, b);   // line 35
      Mult(b, a);  // line 36
      Div(b, a);   // line 37
    } catch (ArithmeticException arithExc) {
      Console.WriteLine("Handling a {0}.", arithExc.GetType().Name);

      //   uncomment EITHER
      //throw arithExc;
      //   OR
      //throw;
      //   OR
      //throw new Exception("We handled and wrapped your exception", arithExc);
    }
  }

  static void Mult(decimal x, decimal y) {
    decimal.Multiply(x, y);
  }
  static void Div(decimal x, decimal y) {
    decimal.Divide(x, y);
  }
}

If you uncomment the throw arithExc; line, your output is:

Handling a DivideByZeroException.
Your stack trace:
   at Program.ThrowTest() in c:\somepath\Program.cs:line 44
   at Program.Main() in c:\somepath\Program.cs:line 9

No inner exception.

Certainly, you have lost information about where that exception happened. If instead you use the throw; line, this is what you get:

Handling a DivideByZeroException.
Your stack trace:
   at System.Decimal.FCallDivide(Decimal& d1, Decimal& d2)
   at System.Decimal.Divide(Decimal d1, Decimal d2)
   at Program.Div(Decimal x, Decimal y) in c:\somepath\Program.cs:line 58
   at Program.ThrowTest() in c:\somepath\Program.cs:line 46
   at Program.Main() in c:\somepath\Program.cs:line 9

No inner exception.

This is a lot better, because now you see that it was the Program.Div method that caused you problems. But it's still hard to see if this problem comes from line 35 or line 37 in the try block.

If you use the third alternative, wrapping in an outer exception, you lose no information:

Handling a DivideByZeroException.
Your stack trace:
   at Program.ThrowTest() in c:\somepath\Program.cs:line 48
   at Program.Main() in c:\somepath\Program.cs:line 9

Stack trace of your inner exception:
   at System.Decimal.FCallDivide(Decimal& d1, Decimal& d2)
   at System.Decimal.Divide(Decimal d1, Decimal d2)
   at Program.Div(Decimal x, Decimal y) in c:\somepath\Program.cs:line 58
   at Program.ThrowTest() in c:\somepath\Program.cs:line 35

In particular you can see that it's line 35 that leads to the problem. However, this requires people to search the InnerException, and it feels somewhat indirect to use inner exceptions in simple cases.

In this blog post they preserve the line number (line of the try block) by calling (through reflection) the internal intance method InternalPreserveStackTrace() on the Exception object. But it's not nice to use reflection like that (the .NET Framework might change their internal members some day without warning).

SELECT a AS current_a, COUNT(*) AS b,
   (SELECT COUNT(*) FROM t WHERE a = current_a AND c = 'const' ) as d
   from t group by a order by b desc

It means it's an array of wide characters (wchar_t) instead of narrow characters (char).

It's a just a string of a different kind of character, not necessarily a Unicode string.

You can do this in Interface Builder.

Select the UIButton you wish to set in IB then go to the attributes inspector.

In the screen shots,I am using a custom button type , but that does not matter.

I just use :-

.clear:after{
  clear: both;
  content: "";
  display: block;
}

Works best and compatible with IE8+ :)

You can't use String.isEmpty() if it is null. Best is to have your own method to check null or empty.

public static boolean isBlankOrNull(String str) {
    return (str == null || "".equals(str.trim()));
}

Use Shell "program file path file path you want to open".

Example:

Shell "c:\windows\system32\mspaint.exe c:users\admin\x.jpg"

It depends on what you need the value for. You (and everyone else so far) omitted the third alternative:

1. static const int var = 5;
2. #define var 5
3. enum { var = 5 };

Ignoring issues about the choice of name, then:

• If you need to pass a pointer around, you must use (1).
• Since (2) is apparently an option, you don't need to pass pointers around.
• Both (1) and (3) have a symbol in the debugger's symbol table - that makes debugging easier. It is more likely that (2) will not have a symbol, leaving you wondering what it is.
• (1) cannot be used as a dimension for arrays at global scope; both (2) and (3) can.
• (1) cannot be used as a dimension for static arrays at function scope; both (2) and (3) can.
• Under C99, all of these can be used for local arrays. Technically, using (1) would imply the use of a VLA (variable-length array), though the dimension referenced by 'var' would of course be fixed at size 5.
• (1) cannot be used in places like switch statements; both (2) and (3) can.
• (1) cannot be used to initialize static variables; both (2) and (3) can.
• (2) can change code that you didn't want changed because it is used by the preprocessor; both (1) and (3) will not have unexpected side-effects like that.
• You can detect whether (2) has been set in the preprocessor; neither (1) nor (3) allows that.

So, in most contexts, prefer the 'enum' over the alternatives. Otherwise, the first and last bullet points are likely to be the controlling factors — and you have to think harder if you need to satisfy both at once.

If you were asking about C++, then you'd use option (1) — the static const — every time.

using a regular expression with the replace function does the trick:

string.replace(/\s/g, "")

I know the topic is a bit old and seems stale, but anyway I was able to use these options:

    deploy:
      resources:
        limits:
          cpus: '0.001'
          memory: 50M

when using 3.7 version of docker-compose

What helped in my case, was using this command:

docker-compose --compatibility up

--compatibility flag stands for (taken from the documentation):

If set, Compose will attempt to convert deploy keys in v3 files to their non-Swarm equivalent

Think it's great, that I don't have to revert my docker-compose file back to v2.

I was getting the same error, for me, it was because API was just returning a string however in fetch call I was expecting json :

response => response.json()

Returning json from API resolved the issue for me, if your API is not supposed to return json then simply don't do response.json()

@Multipart
@POST(Config.UPLOAD_IMAGE)
Observable<Response<String>> uploadPhoto(@Header("Access-Token") String header, @Part MultipartBody.Part imageFile);

And you can call this api like this:

   public void uploadImage(File file) {
     // create multipart
     RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
    MultipartBody.Part body = MultipartBody.Part.createFormData("image", file.getName(), requestFile);

    // upload
    getViewInteractor().showProfileUploadingProgress();

    Observable<Response<String>> observable = api.uploadPhoto("",body);

    // on Response
    subscribeForNetwork(observable, new ApiObserver<Response<String>>() {
        @Override
        public void onError(Throwable e) {
            getViewInteractor().hideProfileUploadingProgress();
        }

        @Override
        public void onResponse(Response<String> response) {

            if (response.code() != 200) {
                Timber.d("error " + response.code());
                return;
            }
            getViewInteractor().hideProfileUploadingProgress();
            getViewInteractor().onProfileImageUploadSuccess(response.body());

        }
    });

}

With 4.0, you will need to manage this yourself by setting the culture for each thread as Alexei describes. But with 4.5, you can define a culture for the appdomain and that is the preferred way to handle this. The relevant apis are CultureInfo.DefaultThreadCurrentCulture and CultureInfo.DefaultThreadCurrentUICulture.

You're calling br.readLine() a second time inside the loop.
Therefore, you end up reading two lines each time you go around.

On Android 5.0 this has changed, you have to call setElevation(0) on your action bar. Note that if you're using the support library you must call it to that like so:

getSupportActionBar().setElevation(0);

It's unaffected by the windowContentOverlay style item, so no changes to styles are required

               display();
           } 
        ?>

You will have to use javascript, or the JQuery framework to do that. her is an example using Jquery

   $('#toggle').click(function () {
        //check if checkbox is checked
        if ($(this).is(':checked')) {

            $('#sendNewSms').removeAttr('disabled'); //enable input

        } else {
            $('#sendNewSms').attr('disabled', true); //disable input
        }
    });

Use window.location.pathname and compare it with your links. You can do something like this:

$('a[href="~/' + currentSiteVar + '/"').addClass('active');

But first you have to prepare currentSiteVar to put it into selecor.

        username = username.Substring(username.IndexOf(@"\") + 1);
        cred = new System.Net.NetworkCredential(username, password, domain);
    } else {
        cred = new System.Net.NetworkCredential(username, password);
    }
    CredentialCache cache = new CredentialCache();
    if (authtype.Contains(":")) {
        authtype = authtype.Substring(authtype.IndexOf(":") + 1); //remove the TMG: prefix
    }
    cache.Add(new Uri(siteurl), authtype, cred);
    return cache;

None of the suggestions here helped me with my situation, but I read something that did give me an answer. I have a ViewController with a fixed set of UI controls followed by a UIWebView. I wanted the entire page to scroll as though the UI controls were connected to the HTML content, so I disable scrolling on the UIWebView and must then set the content size of a parent scroll view correctly.

The important tip turned out to be that UIWebView does not report its size correctly until rendered to the screen. So when I load the content I set the content size to the available screen height. Then, in viewDidAppear I update the scrollview's content size to the correct value. This worked for me because I am calling loadHTMLString on local content. If you are using loadRequest you may need to update the contentSize in webViewDidFinishLoad also, depending on how quickly the html is retrieved.

There is no flickering, because only the invisible part of the scroll view is changed.

Just a note, if you ever see this:

a = x ? : y;

It's a GNU extension to the standard (see https://gcc.gnu.org/onlinedocs/gcc/Conditionals.html#Conditionals).

It is the same as

a = x ? x : y;

This particular error implies that one of the variables being used in the arithmetic on the line has a shape incompatible with another on the same line (i.e., both different and non-scalar). Since n and the output of np.add.reduce() are both scalars, this implies that the problem lies with xm and ym, the two of which are simply your x and y inputs minus their respective means.

Based on this, my guess is that your x and y inputs have different shapes from one another, making them incompatible for element-wise multiplication.

** Technically, it's not that variables on the same line have incompatible shapes. The only problem is when two variables being added, multiplied, etc., have incompatible shapes, whether the variables are temporary (e.g., function output) or not. Two variables with different shapes on the same line are fine as long as something else corrects the issue before the mathematical expression is evaluated.

If you want to put some page in the dialog then you can use these

function Popup()

 width: 600,
 modal:true,
 close: function(event,ui){
     $("pop").dialog('destroy');

        }
 }); 

}

HTML:

Today available Angular 2 rc.7, and I had a similar problem with [email protected] UNMET PEER DEPENDENCY.

If you, like me, simply replaced @angular/...rc.6 to @angular/...rc.7 - it's not enough. Because, for example, @angular/router has no rc.6 version.

In this case, better review package.json in Quick start

Just use the method .decode('base64') and go to be happy.

You need, too, to detect the mimetype/extension of the image, as you can save it correctly, in a brief example, you can use the code below for a django view:

def receive_image(req):
    image_filename = req.REQUEST["image_filename"] # A field from the Android device
    image_data = req.REQUEST["image_data"].decode("base64") # The data image
    handler = open(image_filename, "wb+")
    handler.write(image_data)
    handler.close()

And, after this, use the file saved as you want.

Simple. Very simple. ;)

String one = object.getdata();
Log.d(one,"");

This is the case for me. Simply removing resulted in another error. I followed the steps of this post except the last one. For your convenience, I copied the 4 steps from the post that I followed to solve the problem as following:

1. Right click on the edmx file, select Open with, XML editor
2. Locate the entity in the edmx:StorageModels element
3. Remove the DefiningQuery entirely
4. Rename the store:Schema="dbo" to Schema="dbo" (otherwise, the code will generate an error saying the name is invalid)

Firefox is said to set window.navigator.webdriver === true if working with a webdriver. That was according to one of the older specs (e.g.: archive.org) but I couldn't find it in the new one except for some very vague wording in the appendices.

A test for it is in the selenium code in the file fingerprint_test.js where the comment at the end says "Currently only implemented in firefox" but I wasn't able to identify any code in that direction with some simple greping, neither in the current (41.0.2) Firefox release-tree nor in the Chromium-tree.

I also found a comment for an older commit regarding fingerprinting in the firefox driver b82512999938 from January 2015. That code is still in the Selenium GIT-master downloaded yesterday at javascript/firefox-driver/extension/content/server.js with a comment linking to the slightly differently worded appendix in the current w3c webdriver spec.

You must understand the difference between a class and an instance of that class. If you see a car on the street, you know immediately that it's a car even if you can't see which model or type. This is because you compare what you see with the class "car". The class contains which is similar to all cars. Think of it as a template or an idea.

At the same time, the car you see is an instance of the class "car" since it has all the properties which you expect: There is someone driving it, it has an engine, wheels.

So the class says "all cars have a color" and the instance says "this specific car is red".

In the OO world, you define the class and inside the class, you define a field of type Color. When the class is instantiated (when you create a specific instance), memory is reserved for the color and you can give this specific instance a color. Since these attributes are specific, they are non-static.

Static fields and methods are shared with all instances. They are for values which are specific to the class and not a specific instance. For methods, this usually are global helper methods (like Integer.parseInt()). For fields, it's usually constants (like car types, i.e. something where you have a limited set which doesn't change often).

To solve your problem, you need to instantiate an instance (create an object) of your class so the runtime can reserve memory for the instance (otherwise, different instances would overwrite each other which you don't want).

In your case, try this code as a starting block:

public static void main (String[] args)
{
    try
    {
        MyProgram7 obj = new MyProgram7 ();
        obj.run (args);
    }
    catch (Exception e)
    {
        e.printStackTrace ();
    }
}

// instance variables here

public void run (String[] args) throws Exception
{
    // put your code here
}

The new main() method creates an instance of the class it contains (sounds strange but since main() is created with the class instead of with the instance, it can do this) and then calls an instance method (run()).

I had the same problem. Try this.

The isinstance built-in is the preferred way if you really must, but even better is to remember Python's motto: "it's easier to ask forgiveness than permission"!-) (It was actually Grace Murray Hopper's favorite motto;-). I.e.:

def my_print(text, begin, end):
    "Print 'text' in UPPER between 'begin' and 'end' in lower"
    try:
      print begin.lower() + text.upper() + end.lower()
    except (AttributeError, TypeError):
      raise AssertionError('Input variables should be strings')

This, BTW, lets the function work just fine on Unicode strings -- without any extra effort!-)

Use the ampersand just like you would from the shell.

#!/usr/bin/bash
function_to_fork() {
   ...
}

function_to_fork &
# ... execution continues in parent process ...

Since GNU parallel was not mentioned yet, let me give another way:

cat url.list | parallel -j 8 wget -O {#}.html {}

Generally the first 2 package "words" are your web address in reverse. (You'd have 3 here as convention, if you had a subdomain.)

So something stackoverflow produces would likely be in package com.stackoverflow.whatever.customname

something asp.net produces might be called net.asp.whatever.customname.omg.srsly

something from mysubdomain.toplevel.com would be com.toplevel.mysubdomain.whatever

Beyond that simple convention, the sky's the limit. This is an old linux convention for something that I cannot recall exactly...

What about iterating on the /proc virtual file system ? http://linux.die.net/man/5/proc ?

IMPORTANT: It is safe to remove the workspace for a given Jenkins job as long as the job is not currently running!

NOTE: I am assuming your $JENKINS_HOME is set to the default: /var/jenkins_home.

Clean up one workspace

rm -rf /var/jenkins_home/workspaces/<workspace>

Clean up all workspaces

rm -rf /var/jenkins_home/workspaces/*

Clean up all workspaces with a few exceptions

This one uses grep to create a whitelist:

ls /var/jenkins_home/workspace \ 
  | grep -v -E '(job-to-skip|another-job-to-skip)$' \
  | xargs -I {} rm -rf /var/jenkins_home/workspace/{}

Clean up 10 largest workspaces

This one uses du and sort to list workspaces in order of largest to smallest. Then, it uses head to grab the first 10:

du -d 1 /var/jenkins_home/workspace \
  | sort -n -r \
  | head -n 10 \
  | xargs -I {} rm -rf /var/jenkins_home/workspace/{}

As far as you're concerned once you've "pulled out" the contents with something like .html() it's just a string. You can test that with

<html> 
  <head>
    <title>runthis</title>
    <script type="text/javascript" language="javascript" src="jquery-1.3.2.js"></script>
    <script type="text/javascript">
        $(document).ready( function() {
            var x = $("#foo").html();
            alert( typeof(x) );
        });
    </script>
    </head>
    <body>
        <div id="foo"><table><tr><td>x</td></tr></table><span>xyz</span></div>
    </body>
</html>

The alert text is string. As long as you don't pass it to a parser there's no magic about it, it's a string like any other string.
There's nothing that hinders you from using .post() to send this string back to the server.

edit: Don't pass a string as the parameter data to .post() but an object, like

var data = {
  id: currid,
  html: div_html
};
$.post("http://...", data, ...);

jquery will handle the encoding of the parameters.
If you (for whatever reason) want to keep your string you have to encode the values with something like escape().

var data = 'id='+ escape(currid) +'&html='+ escape(div_html);

Use numpy.delete() - returns a new array with sub-arrays along an axis deleted

numpy.delete(a, index)

For your specific question:

import numpy as np

a = np.array([1, 2, 3, 4, 5, 6, 7, 8, 9])
index = [2, 3, 6]

new_a = np.delete(a, index)

print(new_a) #Prints `[1, 2, 5, 6, 8, 9]`

Note that numpy.delete() returns a new array since array scalars are immutable, similar to strings in Python, so each time a change is made to it, a new object is created. I.e., to quote the delete() docs:

"A copy of arr with the elements specified by obj removed. Note that delete does not occur in-place..."

If the code I post has output, it is the result of running the code.

I think you might see slightly better performance by doing it this way:

$("#Create, #Edit").find(".myClass").plugin(){
    // Options
});

I usually don't have any JAVA_HOME environment variable. Java can set it up itself. Inside java java.home system property should be available.

I had this exact error code and after checking my repository discovered that there were no go files but actually just more directories. So it was more of a red herring than an error for me.

I would recommend doing

go env

and making sure that everything is as it should be, check your environment variables in your OS and check to make sure your shell (bash or w/e ) isn't compromising it via something like a .bash_profile or .bashrc file. good luck.

Why not? You can use switch implementation with equivalent syntax and same semantics. The C language does not have objects and strings objects at all, but strings in C is null terminated strings referenced by pointer. The C++ language have possibility to make overload functions for objects comparision or checking objects equalities. As C as C++ is enough flexible to have such switch for strings for C language and for objects of any type that support comparaison or check equality for C++ language. And modern C++11 allow to have this switch implementation enough effective.

Your code will be like this:

std::string name = "Alice";

std::string gender = "boy";
std::string role;

SWITCH(name)
  CASE("Alice")   FALL
  CASE("Carol")   gender = "girl"; FALL
  CASE("Bob")     FALL
  CASE("Dave")    role   = "participant"; BREAK
  CASE("Mallory") FALL
  CASE("Trudy")   role   = "attacker";    BREAK
  CASE("Peggy")   gender = "girl"; FALL
  CASE("Victor")  role   = "verifier";    BREAK
  DEFAULT         role   = "other";
END

// the role will be: "participant"
// the gender will be: "girl"

It is possible to use more complicated types for example std::pairs or any structs or classes that support equality operations (or comarisions for quick mode).

Features

• any type of data which support comparisions or checking equality
• possibility to build cascading nested switch statemens.
• possibility to break or fall through case statements
• possibility to use non constatnt case expressions
• possible to enable quick static/dynamic mode with tree searching (for C++11)

Sintax differences with language switch is

• uppercase keywords
• need parentheses for CASE statement
• semicolon ';' at end of statements is not allowed
• colon ':' at CASE statement is not allowed
• need one of BREAK or FALL keyword at end of CASE statement

For C++97 language used linear search. For C++11 and more modern possible to use quick mode wuth tree search where return statement in CASE becoming not allowed. The C language implementation exists where char* type and zero-terminated string comparisions is used.

Read more about this switch implementation.

This would also happen when you are trying to restore a newer version backup in a older SQL database. For example when you try to restore a DB backup that is created in 2012 with 110 compatibility and you are trying to restore it in 2008 R2.

Take a look at this. a clean and simple solution using jQuery.

http://jsfiddle.net/ma2Yd/

    <h1 onmouseover="go('The dog is in its shed')" onmouseout="clear()">lalala</h1>
    <div id="goy"></div>


    <script type="text/javascript">

    $(function() {
       $("h1").on('mouseover', function() {
          $("#goy").text('The dog is in its shed');
       }).on('mouseout', function() {
          $("#goy").text("");
       });
   });

SQLAlchemy's ORM is meant to be used together with the SQL layer, not hide it. But you do have to keep one or two things in mind when using the ORM and plain SQL in the same transaction. Basically, from one side, ORM data modifications will only hit the database when you flush the changes from your session. From the other side, SQL data manipulation statements don't affect the objects that are in your session.

So if you say

for c in session.query(Stuff).all():
    c.foo = c.foo+1
session.commit()

it will do what it says, go fetch all the objects from the database, modify all the objects and then when it's time to flush the changes to the database, update the rows one by one.

Instead you should do this:

session.execute(update(stuff_table, values={stuff_table.c.foo: stuff_table.c.foo + 1}))
session.commit()

This will execute as one query as you would expect, and because at least the default session configuration expires all data in the session on commit you don't have any stale data issues.

In the almost-released 0.5 series you could also use this method for updating:

session.query(Stuff).update({Stuff.foo: Stuff.foo + 1})
session.commit()

That will basically run the same SQL statement as the previous snippet, but also select the changed rows and expire any stale data in the session. If you know you aren't using any session data after the update you could also add synchronize_session=False to the update statement and get rid of that select.

You can use border bottom with dotted option.

border-bottom: 1px dotted #807f80;

In my particular case the function was actually missing. The error message is the same. I am using the Postgresql plugin PostGIS and I had to reinstall that for whatever reason.

To me, just go to Project Properties >> Java Build Path >> Order and Export. Uncheck all external library, as the image bellow. It work for me. Hope this help.

If you run into this issue in a fairly complex app it can be cumbersome to refactor all your imports. PyCharm offers a quickfix for this that will automatically change all usage of the imported symbols as well.

This is rather an old question, but I will add my notes for future references.

I had a similar issue and fixed it by changing the order of the exports in the PATH variable.

For example I was using a method of concatenating strings to my PATH by doing (this is just an example):

$> export PATH='$PATH:'$JAVA_HOME

If my variable PATH already had a java in it, the last value would be meaningless, thus the order would matter. To solve this I started inverting it by adding my variable first, then adding the PATH.

Following this idea I inverted the order that ANT_HOME was being exported. Adding JAVA_HOME before ANT_HOME.

This could be just a coincidence, but it worked for me.

Add a file .jslintrc (or .jshintrc in the case of jshint) at the root of your project with the following content:

{
    "node": true
}

I don't think that you'll like it but I made a pair port for python :) using it is some how similar to c++

pair = Pair
pair.make_pair(value1, value2)

or

pair = Pair(value1, value2)

here's the source code pair_stl_for_python

Angular 2-4 route reload hack

For me, using this method inside a root component (component, which is present on any route) works:

onRefresh() {
  this.router.routeReuseStrategy.shouldReuseRoute = function(){return false;};

  let currentUrl = this.router.url + '?';

  this.router.navigateByUrl(currentUrl)
    .then(() => {
      this.router.navigated = false;
      this.router.navigate([this.router.url]);
    });
  }

There are multiple possible causes for this error:

1) When you put the property 'x' inside brackets you are trying to bind to it. Therefore first thing to check is if the property 'x' is defined in your component with an Input() decorator

Your html file:

<body [x]="...">

Your class file:

export class YourComponentClass {

  @Input()
  x: string;
  ...
}

(make sure you also have the parentheses)

2) Make sure you registered your component/directive/pipe classes in NgModule:

@NgModule({
  ...
  declarations: [
    ...,
    YourComponentClass
  ],
  ...
})

See https://angular.io/guide/ngmodule#declare-directives for more details about declare directives.

3) Also happens if you have a typo in your angular directive. For example:

<div *ngif="...">
     ^^^^^

Instead of:

<div *ngIf="...">

This happens because under the hood angular converts the asterisk syntax to:

<div [ngIf]="...">

In order to delete only messages from the queue use :

sudo rabbitmqctl --node <nodename> purge_queue <queue_name>

In order to delete a queue which is empty(--if-empty) or has no consumers(--if-unused) use :

sudo rabbitmqctl --node <nodename> delete_queue <queue_name> --if-empty

or

sudo rabbitmqctl --node <nodename> delete_queue <queue_name> --if-unused 

Here is SQL for setting up an example:

CREATE TABLE employee(name varchar, paymentType varchar, amount bigint);

INSERT INTO employee VALUES('Aaron', 'salary', 100);
INSERT INTO employee VALUES('Aaron', 'bonus', 50);
INSERT INTO employee VALUES('Bob', 'salary', 50);
INSERT INTO employee VALUES('Bob', 'bonus', 0);

The Inject class is vulnerable to SQL injection. The query is dynamically pasted together with user input. The intent of the query was to show information about Bob. Either salary or bonus, based on user input. But the malicious user manipulates the input corrupting the query by tacking on the equivalent of an 'or true' to the where clause so that everything is returned, including the information about Aaron which was supposed to be hidden.

import java.sql.*;

public class Inject {

    public static void main(String[] args) throws SQLException {

        String url = "jdbc:postgresql://localhost/postgres?user=user&password=pwd";
        Connection conn = DriverManager.getConnection(url);

        Statement stmt = conn.createStatement();
        String sql = "SELECT paymentType, amount FROM employee WHERE name = 'bob' AND paymentType='" + args[0] + "'";
        System.out.println(sql);
        ResultSet rs = stmt.executeQuery(sql);

        while (rs.next()) {
            System.out.println(rs.getString("paymentType") + " " + rs.getLong("amount"));
        }
    }
}

Running this, the first case is with normal usage, and the second with the malicious injection:

c:\temp>java Inject salary
SELECT paymentType, amount FROM employee WHERE name = 'bob' AND paymentType='salary'
salary 50

c:\temp>java Inject "salary' OR 'a'!='b"
SELECT paymentType, amount FROM employee WHERE name = 'bob' AND paymentType='salary' OR 'a'!='b'
salary 100
bonus 50
salary 50
bonus 0

You should not build your SQL statements with string concatenation of user input. Not only is it vulnerable to injection, but it has caching implications on the server as well (the statement changes, so less likely to get a SQL statement cache hit whereas the bind example is always running the same statement).

Here is an example of Binding to avoid this kind of injection:

import java.sql.*;

public class Bind {

    public static void main(String[] args) throws SQLException {

        String url = "jdbc:postgresql://localhost/postgres?user=postgres&password=postgres";
        Connection conn = DriverManager.getConnection(url);

        String sql = "SELECT paymentType, amount FROM employee WHERE name = 'bob' AND paymentType=?";
        System.out.println(sql);

        PreparedStatement stmt = conn.prepareStatement(sql);
        stmt.setString(1, args[0]);

        ResultSet rs = stmt.executeQuery();

        while (rs.next()) {
            System.out.println(rs.getString("paymentType") + " " + rs.getLong("amount"));
        }
    }
}

Running this with the same input as the previous example shows the malicious code does not work because there is no paymentType matching that string:

c:\temp>java Bind salary
SELECT paymentType, amount FROM employee WHERE name = 'bob' AND paymentType=?
salary 50

c:\temp>java Bind "salary' OR 'a'!='b"
SELECT paymentType, amount FROM employee WHERE name = 'bob' AND paymentType=?

You also can use regular expressions:

function endsWith($haystack, $needle, $case=true) {
  return preg_match("/.*{$needle}$/" . (($case) ? "" : "i"), $haystack);
}

The poster's second comment from September 21st is spot on. For those who may be coming to this thread later with the same problem as the poster, here is a brief explanation. The other answers are good to keep in mind, but do not address the common issue encountered by this code.

In Swift, declarations made with the let keyword are constants. Of course if you were going to add items to an array, the array can't be declared as a constant, but a segmented control should be fine, right?! Not if you reference the completed segmented control in its declaration.

Referencing the object (in this case a UISegmentedControl, but this also happens with UIButton) in its declaration when you say .addTarget and let the target be self, things crash. Why? Because self is in the midst of being defined. But we do want to define behaviour as part of the object... Declare it lazily as a variable with var. The lazy fools the compiler into thinking that self is well defined - it silences your compiler from caring at the time of declaration. Lazily declared variables don't get set until they are first called. So in this situation, lazy lets you use the notion of self without issue while you set up the object, and then when your object gets a .touchUpInside or .valueChanged or whatever your 3rd argument is in your .addTarget(), THEN it calls on the notion of self, which at that point is fully established and totally prepared to be a valid target. So it lets you be lazy in declaring your variable. In cases like these, I think they could give us a keyword like necessary, but it is generally seen as a lazy, sloppy practice and you don't want to use it all over your code, though it may have its place in this sort of situation. What it

There is no lazy let in Swift (no lazy for constants).

Here is the Apple documentation on lazy.

Here is the Apple on variables and constants. There is a little more in their Language Reference under Declarations.

In Java, a long is a signed 64 bits number, which means you can store numbers between -9,223,372,036,854,775,808 and 9,223,372,036,854,775,807 (inclusive).

A int, on the other hand, is signed 32 bits number, which means you can store number between -2,147,483,648 and 2,147,483,647 (inclusive).

So if your long is outside of the values permitted for an int, you will not get a valuable conversion.

Although this is an old question, I had the same question when using the Standard console version. The answer can be found in the Debian Live manual under the section 10.1 Customizing the live user. It says:

It is also possible to change the default username "user" and the default password "live".

I tried the username user and password live and it did work. If you want to run commands as root you can preface each command with sudo

You can kill a thread by installing trace into the thread that will exit the thread. See attached link for one possible implementation.

Kill a thread in Python

1. Why is this happening?

   The entire ext/mysql PHP extension, which provides all functions named with the prefix mysql_, was officially deprecated in PHP v5.5.0 and removed in PHP v7.

   It was originally introduced in PHP v2.0 (November 1997) for MySQL v3.20, and no new features have been added since 2006. Coupled with the lack of new features are difficulties in maintaining such old code amidst complex security vulnerabilities.

   The manual has contained warnings against its use in new code since June 2011.

2. How can I fix it?

   As the error message suggests, there are two other MySQL extensions that you can consider: MySQLi and PDO_MySQL, either of which can be used instead of ext/mysql. Both have been in PHP core since v5.0, so if you're using a version that is throwing these deprecation errors then you can almost certainly just start using them right away—i.e. without any installation effort.

   They differ slightly, but offer a number of advantages over the old extension including API support for transactions, stored procedures and prepared statements (thereby providing the best way to defeat SQL injection attacks). PHP developer Ulf Wendel has written a thorough comparison of the features.

   Hashphp.org has an excellent tutorial on migrating from ext/mysql to PDO.

3. I understand that it's possible to suppress deprecation errors by setting error_reporting in php.ini to exclude E_DEPRECATED:

   error_reporting = E_ALL ^ E_DEPRECATED
   

   What will happen if I do that?

   Yes, it is possible to suppress such error messages and continue using the old ext/mysql extension for the time being. But you really shouldn't do this—this is a final warning from the developers that the extension may not be bundled with future versions of PHP (indeed, as already mentioned, it has been removed from PHP v7). Instead, you should take this opportunity to migrate your application now, before it's too late.

   Note also that this technique will suppress all E_DEPRECATED messages, not just those to do with the ext/mysql extension: therefore you may be unaware of other upcoming changes to PHP that would affect your application code. It is, of course, possible to only suppress errors that arise on the expression at issue by using PHP's error control operator—i.e. prepending the relevant line with @—however this will suppress all errors raised by that expression, not just E_DEPRECATED ones.

What should you do?

• You are starting a new project.

  There is absolutely no reason to use ext/mysql—choose one of the other, more modern, extensions instead and reap the rewards of the benefits they offer.

• You have (your own) legacy codebase that currently depends upon ext/mysql.

  It would be wise to perform regression testing: you really shouldn't be changing anything (especially upgrading PHP) until you have identified all of the potential areas of impact, planned around each of them and then thoroughly tested your solution in a staging environment.

  • Following good coding practice, your application was developed in a loosely integrated/modular fashion and the database access methods are all self-contained in one place that can easily be swapped out for one of the new extensions.

    Spend half an hour rewriting this module to use one of the other, more modern, extensions; test thoroughly. You can later introduce further refinements to reap the rewards of the benefits they offer.

  • The database access methods are scattered all over the place and cannot easily be swapped out for one of the new extensions.

    Consider whether you really need to upgrade to PHP v5.5 at this time.

    You should begin planning to replace ext/mysql with one of the other, more modern, extensions in order that you can reap the rewards of the benefits they offer; you might also use it as an opportunity to refactor your database access methods into a more modular structure.

    However, if you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

• You are using a third party project that depends upon ext/mysql.

  Consider whether you really need to upgrade to PHP v5.5 at this time.

  Check whether the developer has released any fixes, workarounds or guidance in relation to this specific issue; or, if not, pressure them to do so by bringing this matter to their attention. If you have an urgent need to upgrade PHP right away, you might consider suppressing deprecation errors for the time being: but first be sure to identify any other deprecation errors that are also being thrown.

  It is absolutely essential to perform regression testing.

Always try to use the bufio.NewScanner for collecting input from the console. As others mentioned, there are multiple ways to do the job but Scanner is originally intended to do the job. Dave Cheney explains why you should use Scanner instead of bufio.Reader's ReadLine.

https://twitter.com/davecheney/status/604837853344989184?lang=en

Here is the code snippet answer for your question

package main

import (
    "bufio"
    "fmt"
    "os"
)

/*
 Three ways of taking input
   1. fmt.Scanln(&input)
   2. reader.ReadString()
   3. scanner.Scan()

   Here we recommend using bufio.NewScanner
*/

func main() {
    // To create dynamic array
    arr := make([]string, 0)
    scanner := bufio.NewScanner(os.Stdin)
    for {
        fmt.Print("Enter Text: ")
        // Scans a line from Stdin(Console)
        scanner.Scan()
        // Holds the string that scanned
        text := scanner.Text()
        if len(text) != 0 {
            fmt.Println(text)
            arr = append(arr, text)
        } else {
            break
        }

    }
    // Use collected inputs
    fmt.Println(arr)
}

If you don't want to programmatically collect the inputs, just add these lines

   scanner := bufio.NewScanner(os.Stdin)
   scanner.Scan()
   text := scanner.Text()
   fmt.Println(text)

The output of above program will be:

Enter Text: Bob
Bob
Enter Text: Alice
Alice
Enter Text:
[Bob Alice]

Above program collects the user input and saves them to an array. We can also break that flow with a special character. Scanner provides API for advanced usage like splitting using a custom function etc, scanning different types of I/O streams(Stdin, String) etc.

<div style="text-align:center">
    <span>Short text</span><br />
    <span>This is long text</span>
</div>

This is exactly the same as

while (x--)
{
   printf("%d ", x);
}

for non-negative numbers

We had this issue as well. I cannot remember exactly what fixed as we are now functioning as expected... try grouping the controls. I think that was our resolution.

As of 2017 the best way is to use angular-cli (v1.4.4) for your angular project.

ng build --prod --env=prod --aot --build-optimizer --output-hashing none

You needn't add --aot explicitly as its turned on by default with --prod.And the use of --output-hashing is as per your personal preference regarding cache bursting.

You could explicitly add CDN support by adding :

 --deploy-url "https://<your-cdn-key>.cloudfront.net/"

if you plan to use CDN for hosting which is considerably fast.

You need to run Application.run() because this method starts whole Spring Framework. Code below integrates your main() with Spring Boot.

Application.java

@SpringBootApplication
public class Application {

    public static void main(String[] args) {
        SpringApplication.run(Application.class, args);
    }
}

ReconTool.java

@Component
public class ReconTool implements CommandLineRunner {

    @Override
    public void run(String... args) throws Exception {
        main(args);
    }

    public static void main(String[] args) {
        // Recon Logic
    }
}

Why not SpringApplication.run(ReconTool.class, args)

Because this way spring is not fully configured (no component scan etc.). Only bean defined in run() is created (ReconTool).

Example project: https://github.com/mariuszs/spring-run-magic

A good explanation about how to configure port forwarding with NAT is found in the VirtualBox documents: http://www.virtualbox.org/manual/ch06.html#natforward

function sizeOf(parent_data, size)
{
    for (var prop in parent_data)
    {
        let value = parent_data[prop];

        if (typeof value === 'boolean')
        {
            size += 4;
        }
        else if (typeof value === 'string')
        {
            size += value.length * 2;
        }
        else if (typeof value === 'number')
        {
             size += 8;
        }
        else
        {      
            let oldSize = size;
            size += sizeOf(value, oldSize) - oldSize;
        }
    }

    return size;
}


function roughSizeOfObject(object)
{   
    let size = 0;
    for each (let prop in object)
    {    
        size += sizeOf(prop, 0);
    } // for..
    return size;
}

Here is an example that works on Chrome 5.0.375.125.

The page B (iframe content):

<html>
    <head></head>
    <body>
        <script>
            top.postMessage('hello', 'A');
        </script>
    </body>
</html>

Note the use of top.postMessage or parent.postMessage not window.postMessage here

The page A:

<html>
<head></head>
<body>
    <iframe src="B"></iframe>
    <script>
        window.addEventListener( "message",
          function (e) {
                if(e.origin !== 'B'){ return; } 
                alert(e.data);
          },
          false);
    </script>
</body>
</html>

A and B must be something like http://domain.com

EDIT:

From another question, it looks the domains(A and B here) must have a / for the postMessage to work properly.

I wrote the following JS for a recent project, which was a desktop/mobile/tablet site that has hover effects that shouldn't appear on-touch.

The mobileNoHoverState module below has a variable preventMouseover (initially declared as false), that is set to true when a user fires the touchstart event on an element, $target.

preventMouseover is then being set back to false whenever the mouseover event is fired, which allows the site to work as intended if a user is using both their touchscreen and mouse.

We know that mouseover is being triggered after touchstart because of the order that they are being declared within init.

var mobileNoHoverState = function() {

    var hoverClass = 'hover',
        $target = $(".foo"), 
        preventMouseover = false;

    function forTouchstart() {
        preventMouseover = true;
    }

    function forMouseover() {
        if (preventMouseover === false) {
            $(this).addClass(hoverClass);
        } else {
            preventMouseover = false;
        }
    }

    function forMouseout() {
        $(this).removeClass(hoverClass);
    }

    function init() {
        $target.on({
            touchstart  : forTouchstart,
            mouseover   : forMouseover,
            mouseout    : forMouseout
        });                
    }

    return {
        init: init
    };
}();

The module is then instantiated further down the line:

mobileNoHoverState.init();

-l (that's a lower-case L).

If you add -Wl,--start-group to the linker flags it does not care which order they're in or if there are circular dependencies.

On Qt this means adding:

QMAKE_LFLAGS += -Wl,--start-group

Saves loads of time messing about and it doesn't seem to slow down linking much (which takes far less time than compilation anyway).

Usually this is an OpenSSL version mismatch error, between Apache and PHP. In case Apache loads PHP as a DSO module, its own OpenSSL versions (dlls and libs) will be used. So, in case the PHP extension requires a newer version, it may not find the appropriate interface inside the Apache-loaded DLLS and it will fail to work.

Since you need the PHP extension to load, you need the relevant DLL files to be at least the version of what the PHP module asks for. Supposing that you 're using lastest builds for both Apache and PHP and both having been built with the same MVC version, you can copy the following files:

• libcrypto-1_1.dll
• libcrypto-1_1-x64.dll
• libcurl.dll
• libsasl.dll
• libssh2.dll
• libssl-1_1.dll
• libssl-1_1-x64.dll
• nghttp2.dll
• libeay32.dll (if existing in your PHP distribution)
• ssleay32.dll (if existing in your PHP distribution)

from the PHP root folder to the Apache2/bin folder, in case you 're confident that the PHP build is newer than the Apache build.

In the opposite case, you can copy the same files from the Apache BIN to the PHP root.

In any case, backup the contents of the APache and PHP folders beforehand.

Adding the PHP path as an enviromental variable will give priority to this path for loading the relevant DLLs and may solve the problem. However, you lose in server portability. Additionally, if you have also added the Apache PATH as a variable and the OpenSSL versions are way different (up to loading different linked DLL files), a lot of shit may happen.

I tried the steps that @KannarKK suggested on ES 2.0.2, however, I could not bring the cluster up and running. Evidently, I figured out something, as I had set tcp port number on Master, on the Slave configuration discovery.zen.ping.unicast.hosts needs Master's port number along with IP address ( tcp port number ) for discovery. So when I try following configuration it works for me.

Node 1

cluster.name: mycluster
node.name: "node1"
node.master: true
node.data: true
http.port : 9200
tcp.port : 9300
discovery.zen.ping.multicast.enabled: false
# I think unicast.host on master is redundant.
discovery.zen.ping.unicast.hosts: ["node1.example.com"]

Node 2

cluster.name: mycluster
node.name: "node2"
node.master: false
node.data: true
http.port : 9201
tcp.port : 9301
discovery.zen.ping.multicast.enabled: false
# The port number of Node 1
discovery.zen.ping.unicast.hosts: ["node1.example.com:9300"]

Yes, Daniel is correct, but to expand upon his answer, your primary app component would need to have a navbar component within it. That way, when you render the primary app (any page under the '/' path), it would also display the navbar. I am guessing that you wouldn't want your login page to display the navbar, so that shouldn't be a nested component, and should instead be by itself. So your routes would end up looking something like this:

<Router>
  <Route path="/" component={App}>
    <Route path="page1" component={Page1} />
    <Route path="page2" component={Page2} />
  </Route>
  <Route path="/login" component={Login} />
</Router>

And the other components would look something like this:

var NavBar = React.createClass({
  render() {
    return (
      <div>
        <ul>
          <a onClick={() => history.push('page1') }>Page 1</a>
          <a onClick={() => history.push('page2') }>Page 2</a>
        </ul>
      </div>
    )
  }
});

var App = React.createClass({
  render() {
    return (
      <div>
        <NavBar />
        <div>Other Content</div>
        {this.props.children}
      </div>
    )
  }
});

This is what i've implemented:

$(window).resize(function(){ setTimeout(someFunction, 500); });

we can clear the setTimeout if we expect resize to happen less than 500ms

Good Luck...

I have used

System.AppDomain.CurrentDomain.BaseDirectory

when I want to find a path relative to an applications folder. This works for both ASP.Net and winform applications. It also does not require any reference to System.Web assemblies.

EDIT :
http://codepen.io/gcyrillus/pen/daCyu So for a popup, you have to use position:fixed , display:table property and max-width with em or rem values :) with this CSS basis :

#popup {
  position:fixed;
  width:100%;
  height:100%;
  display:table;
  pointer-events:none;
}
#popup > div {
  display:table-cell;
  vertical-align:middle;
}
#popup p {
  width:80%;
  max-width:20em;
  margin:auto;
  pointer-events:auto;
}

Try use While/Wend and Do While / Loop statements...

i = 1
While i < N + 1
Do While true
    [Code]
    If Condition1 Then
       Exit Do
    End If

    [MoreCode]
    If Condition2 Then
       Exit Do
    End If

    [...]

    Exit Do
Loop
Wend

Just use it as you would a non-concurrent collection. The Concurrent[Collection] classes wrap the regular collections so that you don't have to think about synchronizing access.

Edit: ConcurrentLinkedList isn't actually just a wrapper, but rather a better concurrent implementation. Either way, you don't have to worry about synchronization.

You can also search the DOM using ClassName. For example:

document.getElementsByClassName("myDiv")

This will return an array. If there is one particular property you are interested in. For example:

var divWidth = document.getElementsByClassName("myDiv")[0].clientWidth;

divWidth will now be equal to the the width of the first element in your div array.

htaccess files affect the directory they are placed in and all sub-directories, that is an htaccess file located in your root directory (yoursite.com) would affect yoursite.com/content, yoursite.com/content/contents, etc.

Contrary to what cularis said there can be both in the parameter map.

The best way I see is to proxy the parameterMap and for each parameter retrieval check if queryString contains "&?<parameterName>=".

Note that parameterName needs to be URL encoded before this check can be made, as Qerub pointed out.

That saves you the parsing and still gives you only URL parameters.

JSONObject jsonObject =new JSONObject(jsonStr);
JSONArray jsonArray = jsonObject.getJSONArray("data");
for(int i=0;i<jsonArray.length;i++){
    JSONObject json = jsonArray.getJSONObject(i);
    String id = json.getString("id");
    String name=json.getString("name");
    JSONArray ingArray = json.getJSONArray("Ingredients") // here you are going   to get ingredients
    for(int j=0;j<ingArray.length;j++){
        JSONObject ingredObject= ingArray.getJSONObject(j);
        String ingName = ingredObject.getString("name");//so you are going to get   ingredient name
        Log.e("name",ingName); // you will get 
   }
}

I think the easiest way to accomplish it is to use querystring instead of HTTP headers.

ld is trying to find libcrypto.sowhich is not present as seen in your locate output. You can make a copy of the libcrypto.so.0.9.8 and name it as libcrypto.so. Put this is your ld path. ( If you do not have root access then you can put it in a local path and specify the path manually )

Using the luxon.js library, same can be achieved using startOf and endOf methods by passing the 'day' as parameter

var DateTime = luxon.DateTime;
DateTime.local().startOf('day').toUTC().toISO(); //2017-11-16T18:30:00.000Z
DateTime.local().endOf('day').toUTC().toISO(); //2017-11-17T18:29:59.999Z
DateTime.fromISO(new Date().toISOString()).startOf('day').toUTC().toISO(); //2017-11-16T18:30:00.000Z

remove .toUTC() if you need only the local time

and you may ask why not moment.js, answer is here for that.

There is maybe a bit of a gotcha in the phrasing of the original question:

I need to check that two conditions are both true before enabling a button

The first thing to remember that the ng-disabled directive is evaluating a condition under which the button should be, well, disabled, but the original question is referring to the conditions under which it should en enabled. It will be enabled under any circumstances where the ng-disabled expression is not "truthy".

So, the first consideration is how to rephrase the logic of the question to be closer to the logical requirements of ng-disabled. The logical inverse of checking that two conditions are true in order to enable a button is that if either condition is false then the button should be disabled.

Thus, in the case of the original question, the pseudo-expression for ng-disabled is "disable the button if condition1 is false or condition2 is false". Translating into the Javascript-like code snippet required by Angular (https://docs.angularjs.org/guide/expression), we get:

!condition1 || !condition2

Zoomlar has it right!

1) Go to Xcode Preferences

2) Locate the location tab

3) Set the Xcode verdion in Given Command Line Tools

Now, it ll successfully work.

The variable selectedHero is null in the template so you cannot bind selectedHero.name as is. You need to use the elvis operator ?. for this case:

<input [ngModel]="selectedHero?.name" (ngModelChange)="selectedHero.name = $event" />

The separation of the [(ngModel)] into [ngModel] and (ngModelChange) is also needed because you can't assign to an expression that uses the elvis operator.

I also think you mean to use:

<h2>{{selectedHero?.name}} details!</h2>

instead of:

<h2>{{hero.name}} details!</h2>

How? With annotations.

You simply annotate a POJO with a special annotation and library does the rest.

Warning!

I'm not sure that Hrisey, Lombok, and other code generation libraries are compatible with Android's new build system. They may or may not play nicely with hot swapping code (i.e. jRebel, Instant Run).

Pros:

• Code generation libraries save you from the boilerplate source code.
• Annotations make your class beautiful.

Cons:

• It works well for simple classes. Making a complex class parcelable may be tricky.
• Lombok and AspectJ don't play well together. ^[details]
• See my warnings.

Hrisey

Warning!

Hrisey has a known issue with Java 8 and therefore cannot be used for Android development nowadays. See #1 Cannot find symbol errors (JDK 8).

Hrisey is based on Lombok. Parcelable class using Hrisey:

@hrisey.Parcelable
public final class POJOClass implements android.os.Parcelable {
    /* Fields, accessors, default constructor */
}

Now you don't need to implement any methods of Parcelable interface. Hrisey will generate all required code during preprocessing phase.

Hrisey in Gradle dependencies:

provided "pl.mg6.hrisey:hrisey:${hrisey.version}"

See here for supported types. The ArrayList is among them.

Install a plugin - Hrisey xor Lombok* - for your IDE and start using its amazing features!

* Don't enable Hrisey and Lombok plugins together or you'll get an error during IDE launch.

Parceler

Parcelable class using Parceler:

@java.org.parceler.Parcel
public class POJOClass {
    /* Fields, accessors, default constructor */
}

To use the generated code, you may reference the generated class directly, or via the Parcels utility class using

public static <T> Parcelable wrap(T input);

To dereference the @Parcel, just call the following method of Parcels class

public static <T> T unwrap(Parcelable input);

Parceler in Gradle dependencies:

compile "org.parceler:parceler-api:${parceler.version}"
provided "org.parceler:parceler:${parceler.version}"

Look in README for supported attribute types.

AutoParcel

AutoParcel is an AutoValue extension that enables Parcelable values generation.

Just add implements Parcelable to your @AutoValue annotated models:

@AutoValue
abstract class POJOClass implements Parcelable {
    /* Note that the class is abstract */
    /* Abstract fields, abstract accessors */

    static POJOClass create(/*abstract fields*/) {
        return new AutoValue_POJOClass(/*abstract fields*/);
    }
}

AutoParcel in Gradle build file:

apply plugin: 'com.android.application'
apply plugin: 'com.neenbedankt.android-apt'

repositories {
    /*...*/
    maven {url "https://clojars.org/repo/"}
}

dependencies {
    apt "frankiesardo:auto-parcel:${autoparcel.version}"
}

PaperParcel

PaperParcel is an annotation processor that automatically generates type-safe Parcelable boilerplate code for Kotlin and Java. PaperParcel supports Kotlin Data Classes, Google's AutoValue via an AutoValue Extension, or just regular Java bean objects.

Usage example from docs.
Annotate your data class with @PaperParcel, implement PaperParcelable, and add a JVM static instance of PaperParcelable.Creator e.g.:

@PaperParcel
public final class Example extends PaperParcelable {
    public static final PaperParcelable.Creator<Example> CREATOR = new PaperParcelable.Creator<>(Example.class);

    private final int test;

    public Example(int test) {
        this.test = test;
    }

    public int getTest() {
        return test;
    }
}

For Kotlin users, see Kotlin Usage; For AutoValue users, see AutoValue Usage.

ParcelableGenerator

ParcelableGenerator (README is written in Chinese and I don't understand it. Contributions to this answer from english-chinese speaking developers are welcome)

Usage example from README.

import com.baoyz.pg.Parcelable;

@Parcelable
public class User {

    private String name;
    private int age;

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public int getAge() {
        return age;
    }

    public void setAge(int age) {
        this.age = age;
    }

}

The android-apt plugin assists in working with annotation processors in combination with Android Studio.

If you want to create anonymous array with some values so you can use this syntax.

var arr = new Array(50).fill().map((d,i)=>++i)
console.log(arr)

It seems you don't want to keep the whole DataTable as a copy, because you only need some rows, right? If you got a creteria you can specify with a select on the table, you could copy just those rows to an extra backup array of DataRow like

DataRow[] rows = sourceTable.Select("searchColumn = value");

The .Select() function got several options and this one e.g. can be read as a SQL

SELECT * FROM sourceTable WHERE searchColumn = value;

Then you can import the rows you want as described above.

targetTable.ImportRows(rows[n])

...for any valid n you like, but the columns need to be the same in each table.

Some things you should know about ImportRow is that there will be errors during runtime when using primary keys!

First I wanted to check whether a row already existed which also failed due to a missing primary key, but then the check always failed. In the end I decided to clear the existing rows completely and import the rows I wanted again.

The second issue did help to understand what happens. The way I'm using the import function is to duplicate rows with an exchanged entry in one column. I realized that it always changed and it still was a reference to the row in the array. I first had to import the original and then change the entry I wanted.

The reference also explains the primary key errors that appeared when I first tried to import the row as it really was doubled up.

You can select dropdown option value by name

// deom
jQuery("#option_id").find("option:contains('Monday')").each(function()
{
 if( jQuery(this).text() == 'Monday' )
 {
  jQuery(this).attr("selected","selected");
  }

});

I'm assuming as a developer, you have some degree of administrative control over your machine. If so, from the command line, run msconfig.exe. You can remove many processes from even starting, thereby eliminating the need to kill them with the above mentioned solutions.

You can add full text to an existing instance by changing the SQL Server program in Programs and Features. Follow the steps below. You might need the original disk or ISO for the installation to complete. (Per HotN's comment: If you have SQL Server Express, make sure it is SQL Server Express With Advanced Services.)

Directions:

1. Open the Programs and Features control panel.
2. Select Microsoft SQL Server 2012 and click Change.
3. When prompted to Add/Repair/Remove, select Add.
4. Advance through the wizard until the Feature Selection screen. Then select Full-Text Search.

5. On the Installation Type screen, select the appropriate SQL Server instance.

6. Advance through the rest of the wizard.

There is no difference between using OR ; i.e. it is a convention used by C++ programmers. I myself prefer as it more clearly describes it use; i.e. defining a template with a specific type :)

Note: There is one exception where you do have to use class (and not typename) when declaring a template template parameter:

template <template class T> class C { }; // valid!

template <template typename T> class C { }; // invalid!

In most cases, you will not be defining a nested template definition, so either definition will work -- just be consistent in your use...

Some explanation ignore a condition about the retain cycle [If a group of objects is connected by a circle of strong relationships, they keep each other alive even if there are no strong references from outside the group.] For more information, read the document

This is the only install that resolved the issue for me.

SQL 2008 r2 w/ office 2010 64bit: "2007 Office System Driver: Data Connectivity Components"

The easiest way I have see no achieve most of the same thing at least for one column which is similar to Anamika's answer just with the tuple syntax for the aggregate function.

df.groupby('a').agg(b=('b','unique'), c=('c','unique'))

Please take a look at the sample code below:

function readURL(input) {_x000D_
  if (input.files && input.files[0]) {_x000D_
    var reader = new FileReader();_x000D_

Also, you can try this sample here.

I always use the system types - e.g., Int32 instead of int. I adopted this practice after reading Applied .NET Framework Programming - author Jeffrey Richter makes a good case for using the full type names. Here are the two points that stuck with me:

1. Type names can vary between .NET languages. For example, in C#, long maps to System.Int64 while in C++ with managed extensions, long maps to Int32. Since languages can be mixed-and-matched while using .NET, you can be sure that using the explicit class name will always be clearer, no matter the reader's preferred language.

2. Many framework methods have type names as part of their method names:

   BinaryReader br = new BinaryReader( /* ... */ );
   float val = br.ReadSingle();     // OK, but it looks a little odd...
   Single val = br.ReadSingle();    // OK, and is easier to read
   

Here is another example similar to the previous one, but extended to further demonstrate inflate parameters and dynamic behavior it can provide.

Suppose your ListView row layout can have variable number of TextViews. So first you inflate the base item View (just like the previous example), and then loop dynamically adding TextViews at run-time. Using android:layout_weight additionally aligns everything perfectly.

Here are the Layouts resources:

list_layout.xml

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent" 
    android:layout_height="wrap_content" 
    android:orientation="horizontal" >
    <TextView 
        android:id="@+id/field1"
        android:layout_width="0dp"  
        android:layout_height="wrap_content" 
        android:layout_weight="2"/>
    <TextView 
        android:id="@+id/field2"
        android:layout_width="0dp"  
        android:layout_height="wrap_content" 
        android:layout_weight="1"
/>
</LinearLayout>

schedule_layout.xml

<?xml version="1.0" encoding="utf-8"?>
   <TextView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="0dp"  
    android:layout_height="wrap_content" 
    android:layout_weight="1"/>

Override getView method in extension of BaseAdapter class

@Override
public View getView(int position, View convertView, ViewGroup parent) {
    LayoutInflater inflater = activity.getLayoutInflater();
    View lst_item_view = inflater.inflate(R.layout.list_layout, null);
    TextView t1 = (TextView) lst_item_view.findViewById(R.id.field1);
    TextView t2 = (TextView) lst_item_view.findViewById(R.id.field2);
    t1.setText("some value");
    t2.setText("another value");

    // dinamically add TextViews for each item in ArrayList list_schedule
    for(int i = 0; i < list_schedule.size(); i++){
        View schedule_view = inflater.inflate(R.layout.schedule_layout, (ViewGroup) lst_item_view, false);
        ((TextView)schedule_view).setText(list_schedule.get(i));
        ((ViewGroup) lst_item_view).addView(schedule_view);
    }
    return lst_item_view;
}

Note different inflate method calls:

inflater.inflate(R.layout.list_layout, null); // no parent
inflater.inflate(R.layout.schedule_layout, (ViewGroup) lst_item_view, false); // with parent preserving LayoutParams

The better answers to this only work for specific lengths of lists that are provided.

Here's a version that works for any lengths of input. It also makes the algorithm clear in terms of the mathematical concepts of combination and permutation.

from itertools import combinations, permutations
list1 = ['1', '2']
list2 = ['A', 'B', 'C']

num_elements = min(len(list1), len(list2))
list1_combs = list(combinations(list1, num_elements))
list2_perms = list(permutations(list2, num_elements))
result = [
  tuple(zip(perm, comb))
  for comb in list1_combs
  for perm in list2_perms
]

for idx, ((l11, l12), (l21, l22)) in enumerate(result):
  print(f'{idx}: {l11}{l12} {l21}{l22}')

This outputs:

0: A1 B2
1: A1 C2
2: B1 A2
3: B1 C2
4: C1 A2
5: C1 B2

What do I need to do to make this function wait for the result of the promise?

Use async/await (NOT Part of ECMA6, but available for Chrome, Edge, Firefox and Safari since end of 2017, see canIuse)
MDN

    async function waitForPromise() {
        // let result = await any Promise, like:
        let result = await Promise.resolve('this is a sample promise');
    }

Added due to comment: An async function always returns a Promise, and in TypeScript it would look like:

    async function waitForPromise(): Promise<string> {
        // let result = await any Promise, like:
        let result = await Promise.resolve('this is a sample promise');
    }

This is rather a method than just a single script but gives you much more flexibility.

1. User defined TABLE type [ColumnActionList] -> holds data as parameter

SELECT * FROM ##ALL_Dimentions;
EXECUTE SP_EXECUTESQL @FinalCode;

From executing the first query (by passing source DB and table name) you will get a pre-created execution query for the second SP, all you have to do is define is the column from your source: + Stable + Value (will be used to concentrate values based on that) + Dim (column you want to use to pivot by)

Names and datatypes will be defined automatically!

I cant recommend it for any production environments but does the job for adhoc BI requests.

Although a bit late in posting an answer, here is an alternative approach without using margins.

<style>
    #divMain { width: 500px; }
    #div1 { width: 100px; float: left; background-color: #fcc; }
    #div2 { overflow:hidden; background-color: #cfc; }
    #div3 { width: 100px; float: right; background-color: #ccf; }
</style>

<div id="divMain">
    <div id="div1">
        div 1
    </div>
    <div id="div3">
        div 3
    </div>
    <div id="div2">
        div 2<br />bit taller
    </div>
</div>

This method works like magic, but here is an explanation :)\

Fiddle with a similar sample here.

For Mac users running:

1. Open Android Studio
2. Select Android Studio -> Preferences -> System Settings -> Android SDK
3. Your SDK location will be specified on the upper right side of the screen under [Android SDK Location]

I'm running Android Studio 2.2.3

Adding class using element's classList property:

element.classList.add('my-class-name');

Removing:

element.classList.remove('my-class-name');

You can find the path to php.ini in the output of phpinfo(). See under "Loaded Configuration File".

The values() method returns a QuerySet containing dictionaries:

<QuerySet [{'comment_id': 1}, {'comment_id': 2}]>

The values_list() method returns a QuerySet containing tuples:

<QuerySet [(1,), (2,)]>

If you are using values_list() with a single field, you can use flat=True to return a QuerySet of single values instead of 1-tuples:

<QuerySet [1, 2]>

I think op wants to know what the font that is used on a webpage is, and hoped that info might be findable in the 'inspect' pane.

Try adding the Whatfont Chrome extension.

Perhaps the question needs to be slightly more precise here about what is required because it can be read it two different ways. i.e.

1. How do I get the structure/definition for a table in mysql?
2. How do I get the name of the schema/database this table resides in?

Given the accepted answer, the OP clearly intended it to be interpreted the first way. For anybody reading the question the other way try

SELECT `table_schema` 
FROM `information_schema`.`tables` 
WHERE `table_name` = 'whatever';

Use css() just after show() or fadeIn() like this:

$('div.className').fadeIn().css('display', 'inline-block');

Use:

dateTimePicker.Value.ToString("yyyy/MM/dd")

Refer to the following link:

http://www.vbdotnetforums.com/schedule-time/15001-datetimepicker-format.html

Just try

var file = $("#uploadedfile").prop("files")[0];
var fileName = file.name;
var fileSize = file.size;
alert("Uploading: "+fileName+" @ "+fileSize+"bytes");

It worked for me

Hexyl formats nicely: sudo apt install hexyl

Interestingly enough, very often len(unique()) is a few times (3x-15x) faster than nunique().

ListView operates based on the underlying data in the Adapter. In order to clear the ListView you need to do two things:

1. Clear the data that you set from adapter.
2. Refresh the view by calling notifyDataSetChanged

For example, see the skeleton of SampleAdapter below that extends the BaseAdapter

public class SampleAdapter extends BaseAdapter {

    ArrayList<String> data;

    public SampleAdapter() {
        this.data = new ArrayList<String>();
    }

    public int getCount() {
        return data.size();
    }

    public Object getItem(int position) {
        return data.get(position);
    }

    public long getItemId(int position) {
        return position;
    }

    public View getView(int position, View convertView, ViewGroup parent) {
        // your View
        return null;
    }
}

Here you have the ArrayList<String> data as the data for your Adapter. While you might not necessary use ArrayList, you will have something similar in your code to represent the data in your ListView

Next you provide a method to clear this data, the implementation of this method is to clear the underlying data structure

public void clearData() {
    // clear the data
    data.clear();
}

If you are using any subclass of Collection, they will have clear() method that you could use as above.

Once you have this method, you want to call clearData and notifyDataSetChanged on your onClick thus the code for onClick will look something like:

// listView is your instance of your ListView
SampleAdapter sampleAdapter = (SampleAdapter)listView.getAdapter();
sampleAdapter.clearData();

// refresh the View
sampleAdapter.notifyDataSetChanged();

In case anyone is looking for recursive.

<?php

echo scanDirectoryImages("images");

/**
 * Recursively search through directory for images and display them

function scanDirectoryImages($directory, array $exts = array('jpeg', 'jpg', 'gif', 'png'))
{
    if (substr($directory, -1) == '/') {
        $directory = substr($directory, 0, -1);
    }
    $html = '';
    if (
        is_readable($directory)
        && (file_exists($directory) || is_dir($directory))
    ) {
        $directoryList = opendir($directory);
        while($file = readdir($directoryList)) {
            if ($file != '.' && $file != '..') {
                $path = $directory . '/' . $file;
                if (is_readable($path)) {
                    if (is_dir($path)) {
                        return scanDirectoryImages($path, $exts);
                    }
                    if (
                        is_file($path)
                        && in_array(end(explode('.', end(explode('/', $path)))), $exts)
                    ) {
                        $html .= '<a href="' . $path . '"><img src="' . $path
                            . '" style="max-height:100px;max-width:100px" /></a>';
                    }
                }
            }
        }
        closedir($directoryList);
    }
    return $html;
}

my code is a little complicated but I use it a lot

strftime("%y_%m_%d", localtime(time.time()))

reference:'https://strftime.org/

you can look at the reference to make anything you want for you what YYYY-MM-DD just change my code to:

strftime("%Y-%m-%d", localtime(time.time()))

You can install an indentator package.

Click on File > Extension Manager....

Look for the search field and type: Indentator > Install

Once Indentator is installed, you can use Ctrl + Alt + I

Good question, I was just looking for alternatives to JFreeChart myself the other day. JFreeChart is excellent and very comprehensive, I've used it on several projects. My recent problem was that it meant adding 1.6mb of libraries to a 50kb applet, so I was looking for something smaller.

The JFreeChart FAQ itself lists alternatives. Compared to JFreeChart, most of them are pretty basic, and some pretty ugly. The most promising seem to be the Java Chart Construction Kit and OpenChart2.

I also found EasyCharts, which is a commercial product but seemingly free to use in some circumstances.

In the end, I went back to the tried and trusted JFreeChart and used Proguard to butcher it into a more manageable size.

I suggest that you take another look at JFreeChart. The user guide is only available to buy, but the demo shows what is possible and it's pretty easy to work out how from the API documentation. Basically you start with the ChartFactory static methods and plug the resultant JFreeChart object into a ChartPanel to display it. If you get stuck, I'm sure you'll get some quick answers to your problems on StackOverflow.

I know this is an older post but I was looking for something similar this morning. I feel that my solution was much simpler after looking over some of the other solutions. One thing is that I use font awesome in the anchor tag.

I wanted to display an event on my calendar when the user clicked the event. So I coded a separate <div> tag like so:

<div id="eventContent" class="eventContent" style="display: none; border: 1px solid #005eb8; position: absolute; background: #fcf8e3; width: 30%; opacity: 1.0; padding: 4px; color: #005eb8; z-index: 2000; line-height: 1.1em;">
        <a style="float: right;"><i class="fa fa-times closeEvent" aria-hidden="true"></i></a><br />
        Event: <span id="eventTitle" class="eventTitle"></span><br />
        Start: <span id="startTime" class="startTime"></span><br />
        End: <span id="endTime" class="endTime"></span><br /><br />
</div>

I find it easier to use class names in my jquery since I am using asp.net.

Below is the jquery for my fullcalendar app.

<script>
    $(document).ready(function() {
        $('#calendar').fullCalendar({
            googleCalendarApiKey: 'APIkey',
            header: {
                left: 'prev,next today',
                center: 'title',
                right: 'month,agendaWeek,agendaDay'
            },
            events: {
                googleCalendarId: '@group.calendar.google.com'
            },
            eventClick: function (calEvent, jsEvent, view) {
                var stime = calEvent.start.format('MM/DD/YYYY, h:mm a');
                var etime = calEvent.end.format('MM/DD/YYYY, h:mm a');
                var eTitle = calEvent.title;
                var xpos = jsEvent.pageX;
                var ypos = jsEvent.pageY;
                $(".eventTitle").html(eTitle);
                $(".startTime").html(stime);
                $(".endTime").html(etime);
                $(".eventContent").css('display', 'block');
                $(".eventContent").css('left', '25%');
                $(".eventContent").css('top', '30%');
                return false;
            }
        });
        $(".eventContent").click(function() {
            $(".eventContent").css('display', 'none');
        });
    });
</script>

You must have your own google calendar id and api keys.

I hope this helps when you need a simple popup display.

onStart() called when the activity is becoming visible to the user. onResume() called when the activity will start interacting with the user. You may want to do different things in this cases.

See this link for reference.

int year = 2012;
int month = 12;
int day = 24;
int hour = 0;
int min = 0;
int second = 23;
DateTime dt = new DateTime(year, month, day, hour, min, second);

Just to note that nginx has now support for Websockets on the release 1.3.13. Example of use:

location /websocket/ {

    proxy_pass ?http://backend_host;
    proxy_http_version 1.1;
    proxy_set_header Upgrade $http_upgrade;
    proxy_set_header Connection "upgrade";
    proxy_read_timeout 86400;

}

You can also check the nginx changelog and the WebSocket proxying documentation.

If your constraint is on a user type, then don't forget to see if there is a Default Constraint, usually something like DF__TableName__ColumnName__6BAEFA67, if so then you will need to drop the Default Constraint, like this:

ALTER TABLE TableName DROP CONSTRAINT [DF__TableName__ColumnName__6BAEFA67]

This has a more elegant explanation and more than one possible solutions. http://kasunh.wordpress.com/2011/10/11/preserving-remote-iphost-while-proxying/

The post describes how to use one popular and one lesser known Apache modules to preserve host/ip while in a setup involving proxying.

Use mod_rpaf module, install and enable it in the backend server and add following directives in the module’s configuration. RPAFenable On
RPAFsethostname On
RPAFproxy_ips 127.0.0.1

There are in fact 3 questions in your question :

• Define frontend, middle and back end
• How and when do they overlap ?
• Their associated usual bottlenecks.

What JB King has described is correct, but it is a particular, simple version, where in fact he mapped front, middle and bacn to an MVC layer. He mapped M to the back, V to the front, and C to the middle.

For many people, it is just fine, since they come from the ugly world where even MVC was not applied, and you could have direct DB calls in a view.

However in real, complex web applications, you indeed have two or three different layers, called front, middle and back. Each of them may have an associated database and a controller.

The front-end will be visible by the end-user. It should not be confused with the front-office, which is the UI for parameters and administration of the front. The front-end will usually be some kind of CMS or e-commerce Platform (Magento, etc.)

The middle-end is not compulsory and is where the business logics is. It will be based on a PIM, a MDM tool, or some kind of custom database where you enrich your produts or your articles (for CMS). It'll also be the place where you code business functions that need to be shared between differents frontends (for instance between the PC frontend and the API-based mobile application). Sometimes, an ESB or tool like ActiveMQ will be your middle-end

The back-end will be a 3rd layer, surrouding your source database or your ERP. It may be jsut the API wrting to and reading from your ERP. It may be your supplier DB, if you are doing e-commerce. In fact, it really depends on web projects, but it is always a central repository. It'll be accessed either through a DB call, through an API, or an Hibernate layer, or a full-featured back-end application

This description means that answering the other 2 questions is not possible in this thread, as bottlenecks really depend on what your 3 ends contain : what JB King wrote remains true for simple MVC architectures

at the time the question was asked (5 years ago), maybe the MVC pattern was not yet so widely adopted. Now, there is absolutely no reason why the MVC pattern would not be followed and a view would be tied to DB calls. If you read the question "Are there cases where they MUST overlap, and frontend/backend cannot be separated?" in a broader sense, with 3 different components, then there times when the 3 layers architecture is useless of course. Think of a simple personal blog, you'll not need to pull external data or poll RabbitMQ queues.

If your DBMS supports the notation, you need a separate set of parentheses for each row:

INSERT INTO Data(Col1) VALUES ('Hello'), ('World');

The cross-referenced question shows examples for inserting into two columns.

Alternatively, every SQL DBMS supports the notation using separate statements, one for each row to be inserted:

INSERT INTO Data (Col1) VALUES ('Hello');
INSERT INTO Data (Col1) VALUES ('World');

You need an uppercase M for the month part.

string strDate = DateTime.Now.ToString("MM/dd/yyyy");

Lowercase m is for outputting (and parsing) a minute (such as h:mm).

e.g. a full date time string might look like this:

string strDate = DateTime.Now.ToString("MM/dd/yyyy h:mm");

Notice the uppercase/lowercase mM difference.

Also if you will always deal with the same datetime format string, you can make it easier by writing them as C# extension methods.

public static class DateTimeMyFormatExtensions
{
  public static string ToMyFormatString(this DateTime dt)
  {
    return dt.ToString("MM/dd/yyyy");
  }
}

public static class StringMyDateTimeFormatExtension
{
  public static DateTime ParseMyFormatDateTime(this string s)
  {
    var culture = System.Globalization.CultureInfo.CurrentCulture;
    return DateTime.ParseExact(s, "MM/dd/yyyy", culture);
  }
}

EXAMPLE: Translating between DateTime/string

DateTime now = DateTime.Now;

string strNow = now.ToMyFormatString();
DateTime nowAgain = strNow.ParseMyFormatDateTime();

Note that there is NO way to store a custom DateTime format information to use as default as in .NET most string formatting depends on the currently set culture, i.e.

System.Globalization.CultureInfo.CurrentCulture.

The only easy way you can do is to roll a custom extension method.

Also, the other easy way would be to use a different "container" or "wrapper" class for your DateTime, i.e. some special class with explicit operator defined that automatically translates to and from DateTime/string. But that is dangerous territory.

Unfortunately, crontabs have a very limited environment variables scope, thus you need to export them every time the corntab runs.

An easy approach would be the following example, suppose you've your env vars in a file called env, then:

* * * * * . ./env && /path/to_your/command

this part . ./env will export them and then they're used within the same scope of your command

Example using json

Map<String, Object> data = new HashMap<String, Object>();
    data.put( "name", "Mars" );
    data.put( "age", 32 );
    data.put( "city", "NY" );
    JSONObject json = new JSONObject();
    json.putAll( data );
    System.out.printf( "JSON: %s", json.toString(2) );

output::

JSON: {
  "age": 32,
  "name": "Mars",
  "city": "NY"
}

You can also try to use Google's GSON.Google's GSON is the best library available to convert Java Objects into their JSON representation.

I assume that with interface you mean a C++ class with only pure virtual methods (i.e. without any code), instead with abstract class you mean a C++ class with virtual methods that can be overridden, and some code, but at least one pure virtual method that makes the class not instantiable. e.g.:

class MyInterface
{
public:
  // Empty virtual destructor for proper cleanup
  virtual ~MyInterface() {}

  virtual void Method1() = 0;
  virtual void Method2() = 0;
};


class MyAbstractClass
{
public:
  virtual ~MyAbstractClass();

  virtual void Method1();
  virtual void Method2();
  void Method3();

  virtual void Method4() = 0; // make MyAbstractClass not instantiable
};

In Windows programming, interfaces are fundamental in COM. In fact, a COM component exports only interfaces (i.e. pointers to v-tables, i.e. pointers to set of function pointers). This helps defining an ABI (Application Binary Interface) that makes it possible to e.g. build a COM component in C++ and use it in Visual Basic, or build a COM component in C and use it in C++, or build a COM component with Visual C++ version X and use it with Visual C++ version Y. In other words, with interfaces you have high decoupling between client code and server code.

Moreover, when you want to build DLL's with a C++ object-oriented interface (instead of pure C DLL's), as described in this article, it's better to export interfaces (the "mature approach") instead of C++ classes (this is basically what COM does, but without the burden of COM infrastructure).

I'd use an interface if I want to define a set of rules using which a component can be programmed, without specifying a concrete particular behavior. Classes that implement this interface will provide some concrete behavior themselves.

Instead, I'd use an abstract class when I want to provide some default infrastructure code and behavior, and make it possible to client code to derive from this abstract class, overriding the pure virtual methods with some custom code, and complete this behavior with custom code. Think for example of an infrastructure for an OpenGL application. You can define an abstract class that initializes OpenGL, sets up the window environment, etc. and then you can derive from this class and implement custom code for e.g. the rendering process and handling user input:

// Abstract class for an OpenGL app.
// Creates rendering window, initializes OpenGL; 
// client code must derive from it 
// and implement rendering and user input.
class OpenGLApp
{
public:
  OpenGLApp();
  virtual ~OpenGLApp();
  ...

  // Run the app    
  void Run();


  // <---- This behavior must be implemented by the client ---->

  // Rendering
  virtual void Render() = 0;

  // Handle user input
  // (returns false to quit, true to continue looping)
  virtual bool HandleInput() = 0;

  // <--------------------------------------------------------->


private:
  //
  // Some infrastructure code
  //
  ... 
  void CreateRenderingWindow();
  void CreateOpenGLContext();
  void SwapBuffers();
};


class MyOpenGLDemo : public OpenGLApp
{
public:
  MyOpenGLDemo();
  virtual ~MyOpenGLDemo();

  // Rendering
  virtual void Render();  // implements rendering code

  // Handle user input
  virtual bool HandleInput(); // implements user input handling


  //  ... some other stuff
};

1. Right click on Drawable folder

2. click on new

3. click on image asset

Then you can select an icon type

Probably it's not be correct, and a little bit longer, but I solved this problem (Android Studio) by using this:

System.out.println("Some text here");

Like this:

try {
       ...code here...
} catch(Exception e) {
  System.out.println("Error desc: " + e.getMessage());
}

The commands are adduser and addgroup.

Here's a template for Docker you can use in busybox environments (alpine) as well as Debian-based environments (Ubuntu, etc.):

ENV USER=docker
ENV UID=12345
ENV GID=23456

RUN adduser \
    --disabled-password \
    --gecos "" \
    --home "$(pwd)" \
    --ingroup "$USER" \
    --no-create-home \
    --uid "$UID" \
    "$USER"

Note the following:

• --disabled-password prevents prompt for a password
• --gecos "" circumvents the prompt for "Full Name" etc. on Debian-based systems
• --home "$(pwd)" sets the user's home to the WORKDIR. You may not want this.
• --no-create-home prevents cruft getting copied into the directory from /etc/skel

The usage description for these applications is missing the long flags present in the code for adduser and addgroup.

The following long-form flags should work both in alpine as well as debian-derivatives:

adduser

BusyBox v1.28.4 (2018-05-30 10:45:57 UTC) multi-call binary.

Usage: adduser [OPTIONS] USER [GROUP]

Create new user, or add USER to GROUP

        --home DIR           Home directory
        --gecos GECOS        GECOS field
        --shell SHELL        Login shell
        --ingroup GRP        Group (by name)
        --system             Create a system user
        --disabled-password  Don't assign a password
        --no-create-home     Don't create home directory
        --uid UID            User id

One thing to note is that if --ingroup isn't set then the GID is assigned to match the UID. If the GID corresponding to the provided UID already exists adduser will fail.

addgroup

BusyBox v1.28.4 (2018-05-30 10:45:57 UTC) multi-call binary.

Usage: addgroup [-g GID] [-S] [USER] GROUP

Add a group or add a user to a group

        --gid GID  Group id
        --system   Create a system group

I discovered all of this while trying to write my own alternative to the fixuid project for running containers as the hosts UID/GID.

My entrypoint helper script can be found on GitHub.

The intent is to prepend that script as the first argument to ENTRYPOINT which should cause Docker to infer UID and GID from a relevant bind mount.

An environment variable "TEMPLATE" may be required to determine where the permissions should be inferred from.

(At the time of writing I don't have documentation for my script. It's still on the todo list!!)

If you're making a dictionary only to make a list of tuples, as creating dicts like you are may be a pain, you might look into using zip()

Its especialy useful if you've got one heading, and multiple rows. For instance if I assume that you want Olympics stats for countries:

headers = ['Capital', 'Food', 'Year']
countries = [
    ['London', 'Fish & Chips', '2012'],
    ['Beijing', 'Noodles', '2008'],
]

for olympics in countries:
    print zip(headers, olympics)

gives

[('Capital', 'London'), ('Food', 'Fish & Chips'), ('Year', '2012')]
[('Capital', 'Beijing'), ('Food', 'Noodles'), ('Year', '2008')]

Don't know if thats the end goal, and my be off topic, but it could be something to keep in mind.

Solutions above didn't work. It simply displayed the last key/value pairs, but this did:

http://localhost/?key[]=1&key[]=2

Returns:

Array
(
[key] => Array
    (
        [0] => 1
        [1] => 2
    )

Instead of creating too many short Polylines just create one like here:

PolylineOptions options = new PolylineOptions().width(5).color(Color.BLUE).geodesic(true);
for (int z = 0; z < list.size(); z++) {
    LatLng point = list.get(z);
    options.add(point);
}
line = myMap.addPolyline(options);

I'm also not sure you should use geodesic when your points are so close to each other.

Worked great on CentOS 6.5

yum install bcmath

All my calls to bcmath functions started working right after an apache restart

service httpd restart

Sweet!

Finally it works for me.

private VideoView videoView;

  @Override

       mp.setLooping(true);
       videoView.start();
    }
});

Hope this would help others.

The only reason I'd worry about is that Dog is now allocated on the stack, rather than the heap. So if Dog is megabytes in size, you may have a problem,

If you do need to go the new/delete route, be wary of exceptions. And because of this you should use auto_ptr or one of the boost smart pointer types to manage the object lifetime.

To elaborate on what @Raynos said, the function you have defined is an asynchronous callback. It doesn't execute right away, rather it executes when the file loading has completed. When you call readFile, control is returned immediately and the next line of code is executed. So when you call console.log, your callback has not yet been invoked, and this content has not yet been set. Welcome to asynchronous programming.

Example approaches

const fs = require('fs');
// First I want to read the file
fs.readFile('./Index.html', function read(err, data) {
    if (err) {
        throw err;
    }
    const content = data;

    // Invoke the next step here however you like
    console.log(content);   // Put all of the code here (not the best solution)
    processFile(content);   // Or put the next step in a function and invoke it
});

function processFile(content) {
    console.log(content);
}

Or better yet, as Raynos example shows, wrap your call in a function and pass in your own callbacks. (Apparently this is better practice) I think getting into the habit of wrapping your async calls in function that takes a callback will save you a lot of trouble and messy code.

function doSomething (callback) {
    // any async callback invokes callback with response
}

doSomething (function doSomethingAfter(err, result) {
    // process the async result
});

Here's a slightly different answer building off of S.Lott's answer that gives a list of dates between two dates start and end. In the example below, from the start of 2017 to today.

start = datetime.datetime(2017,1,1)
end = datetime.datetime.today()
daterange = [start + datetime.timedelta(days=x) for x in range(0, (end-start).days)]

If you want to get the file names only without the rest of the commit message you can use:

git log --name-only --pretty=format: <branch name>

This can then be extended to use the various options that contain the file name:

git log --name-status --pretty=format: <branch name>

git log --stat --pretty=format: <branch name>

One thing to note when using this method is that there are some blank lines in the output that will have to be ignored. Using this can be useful if you'd like to see the files that have been changed on a local branch, but is not yet pushed to a remote branch and there is no guarantee the latest from the remote has already been pulled in. For example:

git log --name-only --pretty=format: my_local_branch --not origin/master

Would show all the files that have been changed on the local branch, but not yet merged to the master branch on the remote.

Using Temp table solves the problem but I ran into issues using Exec so I went with the following solution of using sp_executesql:

Create TABLE #tempJoin ( Old_ID int, New_ID int);

declare @table_name varchar(128);

declare @strSQL nvarchar(3072);

set @table_name = 'Object';

--build sql sting to execute
set @strSQL='INSERT INTO '+@table_name+' SELECT '+@columns+' FROM #tempJoin CJ
                        Inner Join '+@table_name+' sourceTbl On CJ.Old_ID = sourceTbl.Object_ID'

**exec sp_executesql @strSQL;**

For me the filename involved was appended with a querystring, which this function didn't like.

$path = 'path/to/my/file.js?v=2'

Solution was to chop that off first:

$path = preg_replace('/\?v=[\d]+$/', '', $path);
$fileTime = filemtime($path);

There are a lot of misconceptions regarding these words.

This is from a previous post (https://stackoverflow.com/a/24582076/3163691) which fits superb here:

1) Critical Section= User object used for allowing the execution of just one active thread from many others within one process. The other non selected threads (@ acquiring this object) are put to sleep.

[No interprocess capability, very primitive object].

2) Mutex Semaphore (aka Mutex)= Kernel object used for allowing the execution of just one active thread from many others, among different processes. The other non selected threads (@ acquiring this object) are put to sleep. This object supports thread ownership, thread termination notification, recursion (multiple 'acquire' calls from same thread) and 'priority inversion avoidance'.

[Interprocess capability, very safe to use, a kind of 'high level' synchronization object].

3) Counting Semaphore (aka Semaphore)= Kernel object used for allowing the execution of a group of active threads from many others. The other non selected threads (@ acquiring this object) are put to sleep.

[Interprocess capability however not very safe to use because it lacks following 'mutex' attributes: thread termination notification, recursion?, 'priority inversion avoidance'?, etc].

4) And now, talking about 'spinlocks', first some definitions:

Critical Region= A region of memory shared by 2 or more processes.

Lock= A variable whose value allows or denies the entrance to a 'critical region'. (It could be implemented as a simple 'boolean flag').

Busy waiting= Continuosly testing of a variable until some value appears.

Finally:

Spin-lock (aka Spinlock)= A lock which uses busy waiting. (The acquiring of the lock is made by xchg or similar atomic operations).

[No thread sleeping, mostly used at kernel level only. Ineffcient for User level code].

As a last comment, I am not sure but I can bet you some big bucks that the above first 3 synchronizing objects (#1, #2 and #3) make use of this simple beast (#4) as part of their implementation.

Have a good day!.

For me it was simply a matter of restarting the docker daemon..

I know this is an old question, but stumbled upon it now and saw nobody mentioned this. so writing it.

The Option one if tweaked like this, it should also work.

The Original

Option One

In the first file:

global $variable; 
$variable = "apple"; 
include('second.php'); 

In the second file:

echo $variable;

TWEAK

In the first file:

$variable = "apple"; 
include('second.php');

In the second file:

global $variable;
echo $variable;

Use PHP DOM to parse and add <br/> in it. Like this:

$html = '<textarea> put returns between paragraphs
for linebreak add 2 spaces at end
indent code by 4 spaces
quote by placing > at start of line
</textarea>';

//parsing begins here:
$doc = new DOMDocument();
@$doc->loadHTML($html);
$nodes = $doc->getElementsByTagName('textarea');

//get text and add <br/> then remove last <br/>
$lines = $nodes->item(0)->nodeValue;

//split it by newlines
$lines = explode("\n", $lines);

//add <br/> at end of each line
foreach($lines as $line)
    $output .= $line . "<br/>";

//remove last <br/>
$output = rtrim($output, "<br/>");

//display it
var_dump($output);

This outputs:

string ' put returns between paragraphs
<br/>for linebreak add 2 spaces at end
<br/>indent code by 4 spaces
<br/>quote by placing > at start of line
' (length=141)

You could try catching the onload event. And stopping the propagation dependent on some flag.

var changeHash = false;

$('ul.questions li a').click(function(event) {
    var $this = $(this)
    $('.tab').hide();  //you can improve the speed of this selector.
    $($this.attr('href')).fadeIn('slow');
    StopEvent(event);  //notice I've changed this
    changeHash = true;
    window.location.hash = $this.attr('href');
});

$(window).onload(function(event){
    if (changeHash){
        changeHash = false;
        StopEvent(event);
    }
}

function StopEvent(event){
    event.preventDefault();
    event.stopPropagation();
    if ($.browser.msie) {
        event.originalEvent.keyCode = 0;
        event.originalEvent.cancelBubble = true;
        event.originalEvent.returnValue = false;
    }
}

Not tested, so can't say if it would work

You can use jquery click action and use the preventDefault() function to avoid postback

<asp:button ID="btnMyButton" runat="server" Text="MyButton" />


$("#btnMyButton").click(function (e) {
// some actions here
 e.preventDefault();
}

#1. Using Array subscript with range

With Swift 5, when you write…

let newNumbers = numbers[0...position]

… newNumbers is not of type Array<Int> but is of type ArraySlice<Int>. That's because Array's subscript(_:?) returns an ArraySlice<Element> that, according to Apple, presents a view onto the storage of some larger array.

Besides, Swift also provides Array an initializer called init(_:?) that allows us to create a new array from a sequence (including ArraySlice).

Therefore, you can use subscript(_:?) with init(_:?) in order to get a new array from the first n elements of an array:

let array = Array(10...14) // [10, 11, 12, 13, 14]
let arraySlice = array[0..<3] // using Range
//let arraySlice = array[0...2] // using ClosedRange also works
//let arraySlice = array[..<3] // using PartialRangeUpTo also works
//let arraySlice = array[...2] // using PartialRangeThrough also works
let newArray = Array(arraySlice)
print(newArray) // prints [10, 11, 12]

#2. Using Array's prefix(_:) method

Swift provides a prefix(_:) method for types that conform to Collection protocol (including Array). prefix(_:) has the following declaration:

func prefix(_ maxLength: Int) -> ArraySlice<Element>

Returns a subsequence, up to maxLength in length, containing the initial elements.

Apple also states:

If the maximum length exceeds the number of elements in the collection, the result contains all the elements in the collection.

Therefore, as an alternative to the previous example, you can use the following code in order to create a new array from the first elements of another array:

let array = Array(10...14) // [10, 11, 12, 13, 14]
let arraySlice = array.prefix(3)
let newArray = Array(arraySlice)
print(newArray) // prints [10, 11, 12]

PHP VERSION >= 5.3.0

Example 1: basic

function test($test_param, $my_function) {
    return $my_function($test_param);
}

test("param", function($param) {
    echo $param;
}); //will echo "param"

Example 2: std object

$obj = new stdClass();
$obj->test = function ($test_param, $my_function) {
    return $my_function($test_param);
};

$test = $obj->test;
$test("param", function($param) {
    echo $param;
});

Example 3: non static class call

class obj{
    public function test($test_param, $my_function) {
        return $my_function($test_param);
    }
}

$obj = new obj();
$obj->test("param", function($param) {
    echo $param;
});

Example 4: static class call

class obj {
    public static function test($test_param, $my_function) {
        return $my_function($test_param);
    }
}

obj::test("param", function($param) {
    echo $param;
});

Below is my simple approach to the issue.

JQuery function:

jQuery.fn.trackClicks = function () {
    if ($(this).attr("data-clicks") === undefined) $(this).attr("data-clicks", 0);

    var timer;
    $(this).click(function () {
        $(this).attr("data-clicks", parseInt($(this).attr("data-clicks")) + 1);

        if (timer) clearTimeout(timer);

        var item = $(this);
        timer = setTimeout(function() {
            item.attr("data-clicks", 0);
        }, 1000);
    });
}

Implementation:

$(function () {
    $("a").trackClicks();

    $("a").click(function () {
        if ($(this).attr("data-clicks") === "2") {
            // Double clicked
        }
    });
});

Inspect the clicked element in Firefox/Chrome to see data-clicks go up and down as you click, adjust time (1000) to suit.

I did some speed testing on various functions to return the full path to all current subdirectories.

tl;dr: Always use scandir:

list_subfolders_with_paths = [f.path for f in os.scandir(path) if f.is_dir()]

Bonus: With scandir you can also simply only get folder names by using f.name instead of f.path.

This (as well as all other functions below) will not use natural sorting. This means results will be sorted like this: 1, 10, 2. To get natural sorting (1, 2, 10), please have a look at https://stackoverflow.com/a/48030307/2441026

Results: scandir is: 3x faster than walk, 32x faster than listdir (with filter), 35x faster than Pathlib and 36x faster than listdir and 37x (!) faster than glob.

Scandir:           0.977
Walk:              3.011
Listdir (filter): 31.288
Pathlib:          34.075
Listdir:          35.501
Glob:             36.277

Tested with W7x64, Python 3.8.1. Folder with 440 subfolders.
In case you wonder if listdir could be speed up by not doing os.path.join() twice, yes, but the difference is basically nonexistent.

Code:

import os
import pathlib
import timeit
import glob

path = r"<example_path>"



def a():
    list_subfolders_with_paths = [f.path for f in os.scandir(path) if f.is_dir()]
    # print(len(list_subfolders_with_paths))


def b():
    list_subfolders_with_paths = [os.path.join(path, f) for f in os.listdir(path) if os.path.isdir(os.path.join(path, f))]
    # print(len(list_subfolders_with_paths))


def c():
    list_subfolders_with_paths = []
    for root, dirs, files in os.walk(path):
        for dir in dirs:
            list_subfolders_with_paths.append( os.path.join(root, dir) )
        break
    # print(len(list_subfolders_with_paths))


def d():
    list_subfolders_with_paths = glob.glob(path + '/*/')
    # print(len(list_subfolders_with_paths))


def e():
    list_subfolders_with_paths = list(filter(os.path.isdir, [os.path.join(path, f) for f in os.listdir(path)]))
    # print(len(list(list_subfolders_with_paths)))


def f():
    p = pathlib.Path(path)
    list_subfolders_with_paths = [x for x in p.iterdir() if x.is_dir()]
    # print(len(list_subfolders_with_paths))



print(f"Scandir:          {timeit.timeit(a, number=1000):.3f}")
print(f"Listdir:          {timeit.timeit(b, number=1000):.3f}")
print(f"Walk:             {timeit.timeit(c, number=1000):.3f}")
print(f"Glob:             {timeit.timeit(d, number=1000):.3f}")
print(f"Listdir (filter): {timeit.timeit(e, number=1000):.3f}")
print(f"Pathlib:          {timeit.timeit(f, number=1000):.3f}")

Here's the list of all Win32 error codes. You can use this page to lookup the error code mentioned in IIS logs:
http://msdn.microsoft.com/en-us/library/ms681381.aspx

You can also use command line utility net to find information about a Win32 error code. The syntax would be:
net helpmsg Win32_Status_Code

InputStream inputStreamObject = PositionKeeperRequestTest.class.getResourceAsStream(jsonFileName);
JSONObject jsonObject = new JSONObject(IOUtils.toString(inputStreamObject));

You can easily write a bit code that will read in a file. You can either assume one sql statement per line, or assume the ;

So, assuming you have a text file such as:

insert into tblTest (t1) values ('2000');

update tbltest set t1 = '2222'
       where id = 5;


insert into tblTest (t1,t2,t3) 
       values ('2001','2002','2003');

Note the in the above text file we free to have sql statements on more then one line.

the code you can use to read + run the above script is:

Sub SqlScripts()

   Dim vSql       As Variant
   Dim vSqls      As Variant
   Dim strSql     As String
   Dim intF       As Integer

   intF = FreeFile()
   Open "c:\sql.txt" For Input As #intF
   strSql = input(LOF(intF), #intF)
   Close intF
   vSql = Split(strSql, ";")

   On Error Resume Next
   For Each vSqls In vSql
      CurrentDb.Execute vSqls
   Next

End Sub

You could expand on placing some error msg if the one statement don't work, such as

if err.number <> 0 then
   debug.print "sql err" & err.Descripiton & "-->" vSqls
end dif

Regardless, the above split() and string read does alow your sql to be on more then one line...

Generally speaking, it's recommended to use MSI-based installations on Windows. Thus, if you're ready to invest a fair bit of time, WiX is the way to go.

If you want something which is much more simpler, go with InnoSetup.
