I liked the solution from Ruidge, but I needed more control from XML. So I changed it to Kotlin and added attributes.

1) Copy the Kotlin class:

import android.content.Context
import android.graphics.*
import android.util.AttributeSet
import android.view.View

class DashedDividerView : View {
constructor(context: Context) : this(context, null, 0)
constructor(context: Context, attributeSet: AttributeSet) : this(context, attributeSet, 0)

companion object {
    const val DIRECTION_VERTICAL = 0
    const val DIRECTION_HORIZONTAL = 1
}

private var dGap = 5.25f
private var dWidth = 5.25f
private var dColor = Color.parseColor("#EE0606")
private var direction = DIRECTION_HORIZONTAL
private val paint = Paint()
private val path = Path()

constructor(context: Context, attrs: AttributeSet?, defStyleAttr: Int) : super(
    context,
    attrs,
    defStyleAttr
) {
    val typedArray = context.obtainStyledAttributes(
        attrs,
        R.styleable.DashedDividerView,
        defStyleAttr,
        R.style.DashedDividerDefault
    )

    dGap = typedArray.getDimension(R.styleable.DashedDividerView_dividerDashGap, dGap)
    dWidth = typedArray.getDimension(R.styleable.DashedDividerView_dividerDashWidth, dWidth)
    dColor = typedArray.getColor(R.styleable.DashedDividerView_dividerDashColor, dColor)
    direction =
        typedArray.getInt(R.styleable.DashedDividerView_dividerDirection, DIRECTION_HORIZONTAL)

    paint.color = dColor
    paint.style = Paint.Style.STROKE
    paint.pathEffect = DashPathEffect(floatArrayOf(dWidth, dGap), 0f)
    paint.strokeWidth = dWidth

    typedArray.recycle()
}

override fun onDraw(canvas: Canvas) {
    super.onDraw(canvas)
    path.moveTo(0f, 0f)

    if (direction == DIRECTION_HORIZONTAL) {
        path.lineTo(measuredWidth.toFloat(), 0f)
    } else {
        path.lineTo(0f, measuredHeight.toFloat())
    }
    canvas.drawPath(path, paint)
}

}

2) Create an attr file in the /res directory and add this

 <declare-styleable name="DashedDividerView">
    <attr name="dividerDashGap" format="dimension" />
    <attr name="dividerDashWidth" format="dimension" />
    <attr name="dividerDashColor" format="reference|color" />
    <attr name="dividerDirection" format="enum">
        <enum name="vertical" value="0" />
        <enum name="horizontal" value="1" />
    </attr>
</declare-styleable>

3) Add a style to the styles file

 <style name="DashedDividerDefault">
    <item name="dividerDashGap">2dp</item>
    <item name="dividerDashWidth">2dp</item>
    <!-- or any color -->
    <item name="dividerDashColor">#EE0606</item>
    <item name="dividerDirection">horizontal</item>
</style>

4) Now you can use the default style

<!-- here will be your path to the class -->
<com.your.package.app.DashedDividerView
    android:layout_width="match_parent"
    android:layout_height="2dp"
    />

or set attributes in XML

<com.your.package.app.DashedDividerView
    android:layout_width="match_parent"
    android:layout_height="2dp"
    app:dividerDirection="horizontal"
    app:dividerDashGap="2dp"
    app:dividerDashWidth="2dp"
    app:dividerDashColor="@color/light_gray"/>

__all__ is used to document the public API of a Python module. Although it is optional, __all__ should be used.

Here is the relevant excerpt from the Python language reference:

The public names defined by a module are determined by checking the module’s namespace for a variable named __all__; if defined, it must be a sequence of strings which are names defined or imported by that module. The names given in __all__ are all considered public and are required to exist. If __all__ is not defined, the set of public names includes all names found in the module’s namespace which do not begin with an underscore character ('_'). __all__ should contain the entire public API. It is intended to avoid accidentally exporting items that are not part of the API (such as library modules which were imported and used within the module).

PEP 8 uses similar wording, although it also makes it clear that imported names are not part of the public API when __all__ is absent:

To better support introspection, modules should explicitly declare the names in their public API using the __all__ attribute. Setting __all__ to an empty list indicates that the module has no public API.

[...]

Imported names should always be considered an implementation detail. Other modules must not rely on indirect access to such imported names unless they are an explicitly documented part of the containing module's API, such as os.path or a package's __init__ module that exposes functionality from submodules.

Furthermore, as pointed out in other answers, __all__ is used to enable wildcard importing for packages:

The import statement uses the following convention: if a package’s __init__.py code defines a list named __all__, it is taken to be the list of module names that should be imported when from package import * is encountered.

The value for an annotation must be a compile time constant, so there is no simple way of doing what you are trying to do.

See also here: How to supply value to an annotation from a Constant java

It is possible to use some compile time tools (ant, maven?) to config it if the value is known before you try to run the program.

Have you tried os.mkdir?

You might also try this little code snippet:

mypath = ...
if not os.path.isdir(mypath):
   os.makedirs(mypath)

makedirs creates multiple levels of directories, if needed.

Use raw keyword, http://twig.sensiolabs.org/doc/api.html#escaper-extension

{{ word | raw }}

In my case, simply "dropping the s" was not the problem (although it is of course a step in the right direction to use the correct package name).

I had to first update the package manager indexes like this:

sudo apt-get update

Then after that the installation worked fine:

sudo apt-get install build-essential

you can extend LinkedHashSet adding your desired getIndex() method. It's 15 minutes to implement and test it. Just go through the set using iterator and counter, check the object for equality. If found, return the counter.

Well guys, the solution to the problem is the following:

1. click in: Start
2. write the word: ejecut
3. After, write: regedit
4. Open the directory: HKEY_LOCAL_MACHINE
5. SOFTWARE
6. Microsoft
7. Windows NT
8. CurrentVersion
9. Perflib
10. Check the following things:

1) Folder 00A: 2) Counter: the last number 3) Help: the last number

   Folder Perflib:
   Last Counter: 00A folder´s Counter 
   Last Help: 00A folder´s Help

Ready, verify the same number in both. success

$fp = fopen('lidn.txt', 'w');
fwrite($fp, 'Cats chase');
fwrite($fp, 'mice');
fclose($fp);

When you export you use the compatibility system set to MYSQL40. Worked for me.

John C is the closest, but XPath is case sensitive, so the correct XPath would be:

/bla/a[contains(@prop, 'Foo')]

Assuming you want to change the url to another within the same domain, you can use this:

history.pushState('data', '', 'http://www.yourcurrentdomain.com/new/path');

For a file:

if exist yourfilename (
  echo Yes 
) else (
  echo No
)

Replace yourfilename with the name of your file.

For a directory:

if exist yourfoldername\ (
  echo Yes 
) else (
  echo No
)

Replace yourfoldername with the name of your folder.

A trailing backslash (\) seems to be enough to distinguish between directories and ordinary files.

SQL Server Management Studio provides an Import/Export wizard tool which have an option to automatically create tables.

You can access it by right clicking on the Database in Object Explorer and selecting Tasks->Import Data...

From there wizard should be self-explanatory and easy to navigate. You choose your CSV as source, desired destination, configure columns and run the package.

If you need detailed guidance, there are plenty of guides online, here is a nice one: http://www.mssqltips.com/sqlservertutorial/203/simple-way-to-import-data-into-sql-server/

One other way, using the splat operator:

*a, last = [1, 3, 4, 5]

STDOUT:
a: [1, 3, 4]
last: 5

Usage:

// Rewrite an ancient unit of length in SI units.
String result = new Rewriter("([0-9]+(\\.[0-9]+)?)[- ]?(inch(es)?)") {
    public String replacement() {
        float inches = Float.parseFloat(group(1));
        return Float.toString(2.54f * inches) + " cm";
    }
}.rewrite("a 17 inch display");
System.out.println(result);

// The "Searching and Replacing with Non-Constant Values Using a
// Regular Expression" example from the Java Almanac.
result = new Rewriter("([a-zA-Z]+[0-9]+)") {
    public String replacement() {
        return group(1).toUpperCase();
    }
}.rewrite("ab12 cd efg34");
System.out.println(result);

Implementation (redesigned):

import java.util.regex.Pattern;

public abstract class Rewriter {
    private Pattern pattern;
    private Matcher matcher;

    public Rewriter(String regularExpression) {
        this.pattern = Pattern.compile(regularExpression);
    }

    public String group(int i) {
        return matcher.group(i);
    }

    public abstract String replacement() throws Exception;

    public String rewrite(CharSequence original) {
        return rewrite(original, new StringBuffer(original.length())).toString();
    }

    public StringBuffer rewrite(CharSequence original, StringBuffer destination) {
        try {
            this.matcher = pattern.matcher(original);
            while (matcher.find()) {
                matcher.appendReplacement(destination, "");
                destination.append(replacement());
            }
            matcher.appendTail(destination);
            return destination;
        } catch (Exception e) {
            throw new RuntimeException("Cannot rewrite " + toString(), e);
        }
    }

    @Override
    public String toString() {
        StringBuilder sb = new StringBuilder();
        sb.append(pattern.pattern());
        for (int i = 0; i <= matcher.groupCount(); i++)
            sb.append(format("\n\t(%s) - %s", i, group(i)));
        return sb.toString();
    }
}

Its undefined because, console.log(response) runs before doCall(urlToCall); is finished. You have to pass in a callback function aswell, that runs when your request is done.

First, your function. Pass it a callback:

function doCall(urlToCall, callback) {
    urllib.request(urlToCall, { wd: 'nodejs' }, function (err, data, response) {                              
        var statusCode = response.statusCode;
        finalData = getResponseJson(statusCode, data.toString());
        return callback(finalData);
    });
}

Now:

var urlToCall = "http://myUrlToCall";
doCall(urlToCall, function(response){
    // Here you have access to your variable
    console.log(response);
})

@Rodrigo, posted a good resource in the comments. Read about callbacks in node and how they work. Remember, it is asynchronous code.

mkdirs() will create the specified directory path in its entirety where mkdir() will only create the bottom most directory, failing if it can't find the parent directory of the directory it is trying to create.

In other words mkdir() is like mkdir and mkdirs() is like mkdir -p.

For example, imagine we have an empty /tmp directory. The following code

new File("/tmp/one/two/three").mkdirs();

would create the following directories:

• /tmp/one
• /tmp/one/two
• /tmp/one/two/three

Where this code:

new File("/tmp/one/two/three").mkdir();

would not create any directories - as it wouldn't find /tmp/one/two - and would return false.

That is brilliant, the only answer I found that met my particular need, thanks SO much for putting it up!

I made just a minor addition to it so that the screen didn't flash and it removes and subsequently reapplies the password on each sheet as it cycles through [I have the same password for all sheets in the workbook]. In the spirit of your submission, I add this to assist anyone else....

Sub ClearFilters()
    Application.ScreenUpdating = False

    On Error Resume Next
    For Each wrksheet In ActiveWorkbook.Worksheets
        'Change the password to whatever is required
        wrksheet.Unprotect Password:="Albuterol1"
        wrksheet.ShowAllData 'This works for filtered data not in a table

        For Each lstobj In wrksheet.ListObjects
            If lstobj.ShowAutoFilter Then
                lstobj.Range.AutoFilter 'Clear filters from a table
                lstobj.Range.AutoFilter 'Add the filters back to the table
            End If

        'Change the password to whatever is required
        wrksheet.Protect Password:="Albuterol1", _
              DrawingObjects:=True, _
              Contents:=True, _
              Scenarios:=True, _
              AllowFiltering:=True
        Next 'Check next worksheet in the workbook
    Next

    Application.ScreenUpdating = True
End Sub

I know this is a relatively old post and don't really like being a necromancer... But since I had the same issue and tried a few of the options in this thread without success I combined some of the answers to get a working macro..

Hopefully this helps someone out there :)

Sub ResetFilters()
    On Error Resume Next
    For Each wrksheet In ActiveWorkbook.Worksheets
        wrksheet.ShowAllData 'This works for filtered data not in a table
        For Each lstobj In wrksheet.ListObjects
            If lstobj.ShowAutoFilter Then
                lstobj.Range.AutoFilter 'Clear filters from a table
                lstobj.Range.AutoFilter 'Add the filters back to the table
            End If
        Next 'Check next worksheet in the workbook
    Next
End Sub

Here is code you can directly copy paste :

String imageName = "picture1.jpg";
String [] imageNameArray = imageName.split("\\.");
for(int i =0; i< imageNameArray.length ; i++)
{
   system.out.println(imageNameArray[i]);
}

And what if mistakenly there are spaces left before or after "." in such cases? It's always best practice to consider those spaces also.

String imageName = "picture1  . jpg";
String [] imageNameArray = imageName.split("\\s*.\\s*");
    for(int i =0; i< imageNameArray.length ; i++)
    {
       system.out.println(imageNameArray[i]);
    }

Here, \\s* is there to consider the spaces and give you only required splitted strings.

You can explicitly specify the return type of a lambda by using -> Type after the arguments list:

[]() -> Type { }

However, if a lambda has one statement and that statement is a return statement (and it returns an expression), the compiler can deduce the return type from the type of that one returned expression. You have multiple statements in your lambda, so it doesn't deduce the type.

If you use the DateTime.ParseExact()-method that several people have suggested, you should carefully consider what you want to happen when the application runs in a non-English environment!

In Denmark, which of ParseExact("Januar", ...) and ParseExact("January", ...) should work and which should fail?

That will be the difference between CultureInfo.CurrentCulture and CultureInfo.InvariantCulture.

I got the answer to my own question, ant this is:

select reverse(stuff(reverse('a,b,c,d,'), 1, N, ''))

Where N is the number of characters to remove. This avoids to write the complex column/string twice

A solution using retype() from hablar to coerce factors to character or numeric type depending on feasability. I'd use dplyr for applying max to each column.

Code

library(dplyr)
library(hablar)

# Retype() simplifies each columns type, e.g. always removes factors
d <- d %>% retype()

# Check max for each column
d %>% summarise_all(max)

Result

Not the new column types.

     v1 v2       v3 v4   
  <dbl> <chr> <dbl> <chr>
1 0.974 j      1.09 J   

Data

# Sample data borrowed from @joran
d <- data.frame(v1 = runif(10), v2 = letters[1:10], 
                v3 = rnorm(10), v4 = LETTERS[1:10],stringsAsFactors = TRUE)

You need the cat (short for concatenate) command, with shell redirection (>) into your output file

cat 1.txt 2.txt 3.txt > 0.txt

Here is another cheat:

Limit your query if you don't really need all the rows. i.e.

WHERE rownum <= 10000

Then click on any cell of the results and do from your keyboard CTRL+END. This will force SQL Developer to scroll until the bottom result of your query.

This has the advantage of keeping the default behavior and use this on demand.

Compilating answers here and there, here's a complete set of arr tools to get the work done:

Function getArraySize(arr As Variant)
' returns array size for a n dimention array
' usage result(k) = size of the k-th dimension

Dim ndims As Long
Dim arrsize() As Variant
ndims = getDimensions(arr)
ReDim arrsize(ndims - 1)
For i = 1 To ndims
    arrsize(i - 1) = getDimSize(arr, i)
Next i
getArraySize = arrsize
End Function

Function getDimSize(arr As Variant, dimension As Integer)
' returns size for the given dimension number
    getDimSize = UBound(arr, dimension) - LBound(arr, dimension) + 1
End Function

Function getDimensions(arr As Variant) As Long
' returns number of dimension in an array (ex. sheet range = 2 dimensions)
    On Error GoTo Err
    Dim i As Long
    Dim tmp As Long
    i = 0
    Do While True
        i = i + 1
        tmp = UBound(arr, i)
    Loop
Err:
    getDimensions = i - 1
End Function

I know its late, but I recently had this requirement and came up with the below code. I don't have a choice to use User defined function. Hope this helps.

SELECT 
    SUBSTRING(
                SUBSTRING('Hello John Smith' ,0,CHARINDEX(' ','Hello John Smith',CHARINDEX(' ','Hello John Smith')+1)
                        ),CHARINDEX(' ','Hello John Smith'),LEN('Hello John Smith')
            )

I needed to enable the JUnit plugin, after I linked my project with the jar files.

To enable the JUnit plugin, go to File->Settings, type "JUnit" in the search bar, and under "Plugins," check "JUnit.

vikingsteve's advice above will probably get the libraries linked right. Otherwise, open File->Project Structure, go to Libraries, hit the plus, and then browse to

C:\Program Files (x86)\JetBrains\IntelliJ IDEA Community Edition 14.1.1\lib\

and add these jar files:

hamcrest-core-1.3.jar
junit-4.11.jar 
junit.jar 

DTO is an abbreviation for Data Transfer Object, so it is used to transfer the data between classes and modules of your application.

• DTO should only contain private fields for your data, getters, setters, and constructors.
• DTO is not recommended to add business logic methods to such classes, but it is OK to add some util methods.

DAO is an abbreviation for Data Access Object, so it should encapsulate the logic for retrieving, saving and updating data in your data storage (a database, a file-system, whatever).

Here is an example of how the DAO and DTO interfaces would look like:

interface PersonDTO {
    String getName();
    void setName(String name);
    //.....
}

interface PersonDAO {
    PersonDTO findById(long id);
    void save(PersonDTO person);
    //.....
}

The MVC is a wider pattern. The DTO/DAO would be your model in the MVC pattern.
It tells you how to organize the whole application, not just the part responsible for data retrieval.

As for the second question, if you have a small application it is completely OK, however, if you want to follow the MVC pattern it would be better to have a separate controller, which would contain the business logic for your frame in a separate class and dispatch messages to this controller from the event handlers.
This would separate your business logic from the view.

You can use dangerouslySetInnerHTML to do this:

import React from 'react';
function iframe() {
    return {
        __html: '<iframe src="./Folder/File.html" width="540" height="450"></iframe>'
    }
}


export default function Exercises() {
    return (
        <div>
            <div dangerouslySetInnerHTML={iframe()} />
        </div>)
}

HTML files must be in the public folder

Class WebMvcConfigurerAdapter is deprecated as of 5.0 WebMvcConfigurer has default methods and can be implemented directly without the need for this adapter. For this case:

@Configuration
@EnableWebMvc
public class WebMvcConfig implements WebMvcConfigurer {
    @Override
    public void addCorsMappings(CorsRegistry registry) {
        registry.addMapping("/**").allowedOrigins("http://localhost:3000");
    }
}

An adventage of use ExpectedException Rule (version 4.7) is that you can test exception message and not only the expected exception.

And using Matchers, you can test the part of message you are interested:

exception.expectMessage(containsString("income: -1000.0"));

I have used the above option to .hide entries from 2 drops down boxes (first you select the city, then you selected the area within that city). It works fine on screen but the hidden options are still selectable via keyboard inputs.

cache = {}
def fib(n):
    if n <= 1:
        return n
    else:
        if n not in cache:
            cache[n] = fib(n-1) + fib(n-2)
        return cache[n]

All work perfectly :)

 NSString *test = @"test";
 unichar a;

    NSLog(@"Char at index %d cannot be found", index);
    NSLog(@"Max index is: %lu", [test length] - 1);
 }
 @finally {
    NSLog(@"Finally condition");
 }

Log:

Definitely the easiest way to do that is using Gson's default parsing function fromJson().

There is an implementation of this function suitable for when you need to deserialize into any ParameterizedType (e.g., any List), which is fromJson(JsonElement json, Type typeOfT).

In your case, you just need to get the Type of a List<String> and then parse the JSON array into that Type, like this:

import java.lang.reflect.Type;
import com.google.gson.reflect.TypeToken;

JsonElement yourJson = mapping.get("servers");
Type listType = new TypeToken<List<String>>() {}.getType();

List<String> yourList = new Gson().fromJson(yourJson, listType);

In your case yourJson is a JsonElement, but it could also be a String, any Reader or a JsonReader.

You may want to take a look at Gson API documentation.

I have managed to get my PDA working properly with Windows 10.

For transparency when I posted the original question I had upgraded a Windows 8.1 PC to Windows 10, I have since moved to using a different PC that had a clean Windows 10 installation.

These are the steps I followed to solve the problem:

• First of all I installed Visual Studio 2008.
• Then I installed Microsoft Windows Mobile Device Center 6.1
  • http://www.microsoft.com/en-us/download/details.aspx?id=3182
• Then Windows Mobile 6 Professional and Standard Software Development Kits Refresh
  • http://www.microsoft.com/en-us/download/details.aspx?id=6135
• Then Windows Mobile 6.5 Developer Tool Kit
  • http://www.microsoft.com/en-us/download/details.aspx?id=17284
• Finally I opened up the Mobile Device Center, went to Mobile Device Settings -> Connection Settings and made sure DMA was selected under "Allow connections to one of the following"

There is an open-source library that has such a function, and it has cross-platform implementations: https://github.com/OpenHFT/Java-Thread-Affinity

It may be overkill just to get the PID, but if you want other things like CPU and thread id, and specifically thread affinity, it may be adequate for you.

To get the current thread's PID, just call Affinity.getAffinityImpl().getProcessId().

This is implemented using JNA (see arcsin's answer).

<form name="myForm">_x000D_
        <input name="myText" type="text" ng-model="mytext" required/>_x000D_
        <button ng-disabled="myForm.$pristine|| myForm.$invalid">Save</button>_x000D_
</form>

If you want to be a bit more strict

Rather than using if statements might I suggest using a switch instead, I try to avoid using if statements when possible.

var result = MessageBox.Show(@"Do you want to save the changes?", "Confirmation", MessageBoxButtons.YesNoCancel);
switch (result)
{
    case DialogResult.Yes:
        SaveChanges();
        break;
    case DialogResult.No:
        Rollback();
        break;
    default:
        break;
}

If you are using ES6 (Babel) or TypeScript you can stub out the property using get and set accessors

export class SomeClassStub {
  getValueA = jasmine.createSpy('getValueA');
  setValueA = jasmine.createSpy('setValueA');
  get valueA() { return this.getValueA(); }
  set valueA(value) { this.setValueA(value); }
}

Then in your test you can check that the property is set with:

stub.valueA = 'foo';

expect(stub.setValueA).toHaveBeenCalledWith('foo');

Even if you are using IIS or apache, in my guess you are using static html page as a landing page, and by default the web server doesn't allow POST or GET verb on .html page, facebook calls your page via POST/GET verb

the solution would be to rename the page into .php or .aspx and you should be good to go :)

Or just use Apache CXF's wsdl2java to generate objects you can use.

It is included in the binary package you can download from their website. You can simply run a command like this:

$ ./wsdl2java -p com.mynamespace.for.the.api.objects -autoNameResolution http://www.someurl.com/DefaultWebService?wsdl

It uses the wsdl to generate objects, which you can use like this (object names are also grabbed from the wsdl, so yours will be different a little):

DefaultWebService defaultWebService = new DefaultWebService();
String res = defaultWebService.getDefaultWebServiceHttpSoap11Endpoint().login("webservice","dadsadasdasd");
System.out.println(res);

There is even a Maven plug-in which generates the sources: https://cxf.apache.org/docs/maven-cxf-codegen-plugin-wsdl-to-java.html

Note: If you generate sources using CXF and IDEA, you might want to look at this: https://stackoverflow.com/a/46812593/840315

Another way of joining two lines without placing cursor to that line is:

:6,6s#\n##

Here 6 is the line number to which another line will be join. To display the line number, use :set nu.

If we are on the cursor where the next line should be joined, then:

:s#\n##

In both cases we don't need g like :s#\n##g, because on one line only one \n exist.

This XPath is specific to the code snippet you've provided. To select <child> with id as #grand you can write //child[@id='#grand'].

To get age //child[@id='#grand']/@age

Hope this helps

This is the format of /etc/crontab:

# .---------------- minute (0 - 59)
# |  .------------- hour (0 - 23)
# |  |  .---------- day of month (1 - 31)
# |  |  |  .------- month (1 - 12) OR jan,feb,mar,apr ...
# |  |  |  |  .---- day of week (0 - 6) (Sunday=0 or 7) OR sun,mon,tue,wed,thu,fri,sat
# |  |  |  |  |
# *  *  *  *  * user-name  command to be executed

I recommend copy & pasting that into the top of your crontab file so that you always have the reference handy. RedHat systems are setup that way by default.

To run something every minute:

* * * * * username /var/www/html/a.php

To run something at midnight of every day:

0 0 * * * username /var/www/html/reset.php

You can either include /usr/bin/php in the command to run, or you can make the php scripts directly executable:

chmod +x file.php

Start your php file with a shebang so that your shell knows which interpreter to use:

#!/usr/bin/php
<?php
// your code here

Add one more property in your view model, which will return reverse value. And bind that to button. Like;

The file extension .img does not say anything about its content.

Most commonly .img files are a floppy/CD/DVD/ISO image, a filesystem image, a disk image, or even just (custom) binary data.

In case it is an CD/DVD image or a specific filesystem image (like fat, ntfs, ...) you can open these files with 7-Zip.

On *nix based systems also the file tool or (libmagic) could help you find out what it is.

In case anyone else has the same issue as this on

Centos, try:

yum install python-lxml

Ubuntu

sudo apt-get install -y python-lxml

worked for me.

Delete package-lock.json it works for me

then npm install

There are a few OS-specific routines for beeping.

• On a Unix-like OS, try the (n)curses beep() function. This is likely to be more portable than writing '\a' as others have suggested, although for most terminal emulators that will probably work.

• In some *BSDs there is a PC speaker device. Reading the driver source, the SPKRTONE ioctl seems to correspond to the raw hardware interface, but there also seems to be a high-level language built around write()-ing strings to the driver, described in the manpage.

• It looks like Linux has a similar driver (see this article for example; there is also some example code on this page if you scroll down a bit.).

• In Windows there is a function called Beep().

Margin

Margin is usually used to create a space between the element itself and its surround.

for example I use it when I'm building a navbar to make it sticks to the edges of the screen and for no white gap.

Padding

I usually use when I've an element inside a border, <div> or something similar, and I want to decrease its size but at the time I want to keep the distance or the margin between the other elements around it.

So briefly, it's situational; it depends on what you are trying to do.

Check your current project that whether you have made back copy with same class name and different page name (Class name will inherit copied file). Ultimately that will confuse the compiler!!!

CodeFile="Consolidated.aspx.vb" Inherits="Consolidated

You're being mislead by output -- the second approach you're taking actually does what you want, you just aren't believing it. :)

>>> foo = 'baz "\\"'
>>> foo
'baz "\\"'
>>> print(foo)
baz "\"

Incidentally, there's another string form which might be a bit clearer:

>>> print(r'baz "\"')
baz "\"

I was going out of my mind when a rule was being ignored while others weren't. Run your CSS through a validator and look for parsing errors.

I accidentally used // for a comment instead of /* */ causing odd behavior. My IDE said nothing about it. I hope it helps someone.

I've had this problem in the past, so I bookmarked this discussion.

To summarize it, you can:

1. Take a look at this circle filter's source code and figure out how to incorporate it into your project.
2. Draw a GPolygon with enough points to simulate a circle.
3. Generate a KML file by modifying http://www.nearby.org.uk/google/circle.kml.php?radius=30miles&lat=40.173&long=-105.1024 and then importing it. In Google Maps, you can just paste the URI in the search box and it will display on the map. I'm not sure how you might do it using the API though.

Laravel 4+ offers you these methods: whereDay(), whereMonth(), whereYear() (#3946) and whereDate() (#6879).

They do the SQL DATE() work for you, and manage the differences of SQLite.

Your result can be achieved as so:

->whereDate('date', '<=', '2014-07-10')

For more examples, see first message of #3946 and this Laravel Daily article.

Update: Though the above method is convenient, as noted by Arth it is inefficient on large datasets, because the DATE() SQL function has to be applied on each record, thus discarding the possible index.

Here are some ways to make the comparison (but please read notes below):

->where('date', '<=', '2014-07-10 23:59:59')

->where('date', '<', '2014-07-11')

// '2014-07-11'
$dayAfter = (new DateTime('2014-07-10'))->modify('+1 day')->format('Y-m-d');

->where('date', '<', $dayAfter)

Notes:

• 23:59:59 is okay (for now) because of the 1-second precision, but have a look at this article: 23:59:59 is not the end of the day. No, really!
• Keep in mind the "zero date" case ("0000-00-00 00:00:00"). Though, these "zero dates" should be avoided, they are source of so many problems. Better make the field nullable if needed.

if multiple (x) rows in Dim_Member are associated with a single row in Susp_Visits, there will be x rows in the resul set.

For a colloquial name there is "splatting".

For arguments (list type) you use single * and for keyword arguments (dictionary type) you use double **.

Both * and ** is sometimes referred to as "splatting".

See for reference of this name being used: https://stackoverflow.com/a/47875892/14305096

Assuming container is only on page once and you are using jQuery, then:

var containerEl = $('.container')[0];
var scrollbarWidth = containerEl.offsetWidth - containerEl.clientWidth;

Also see this answer for more details.

Even if you write a regular expression that matches exactly the subset "valid phone numbers" out of strings, there is no way to guarantee (by way of a regular expression) that they are valid mobile phone numbers. In several countries, mobile phone numbers are indistinguishable from landline phone numbers without at least a number plan lookup, and in some cases, even that won't help. For example, in Sweden, lots of people have "ported" their regular, landline-like phone number to their mobile phone. It's still the same number as they had before, but now it goes to a mobile phone instead of a landline.

Since valid phone numbers consist only of digits, I doubt that rolling your own would risk missing some obscure case of phone number at least. If you want to have better certainty, write a generator that takes a list of all valid country codes, and requires one of them at the beginning of the phone number to be matched by the generated regular expression.

You should use the built in line separator. The advantage is that you don't have to concern what system you code is running on, it will just work.

Since Java 1.7

System.lineSeparator()

Pre Java 1.7

System.getProperty("line.separator")

You can also use this

$user = User::whereEmail($email)->first();

As noted in other answers, pthreads does not define a platform-independent way to retrieve an integral thread ID.

On Linux systems, you can get thread ID thus:

#include <sys/types.h>
pid_t tid = gettid();

On many BSD-based platforms, this answer https://stackoverflow.com/a/21206357/316487 gives a non-portable way.

However, if the reason you think you need a thread ID is to know whether you're running on the same or different thread to another thread you control, you might find some utility in this approach

static pthread_t threadA;

// On thread A...
threadA = pthread_self();

// On thread B...
pthread_t threadB = pthread_self();
if (pthread_equal(threadA, threadB)) printf("Thread B is same as thread A.\n");
else printf("Thread B is NOT same as thread A.\n");

If you just need to know if you're on the main thread, there are additional ways, documented in answers to this question how can I tell if pthread_self is the main (first) thread in the process?.

eduffy had a good idea. He just got it backwards in his code example. Either in JavaScript or in SQLite you can replace the apostrophe with the accent symbol.

He (accidentally I am sure) placed the accent symbol as the delimiter for the string instead of replacing the apostrophe in O'Brian. This is in fact a terrifically simple solution for most cases.

Once you have a JArray you can treat it just like any other Enumerable object, and using linq you can access them, check them, verify them, and select them.

var str = @"[1, 2, 3]";
var jArray = JArray.Parse(str);
Console.WriteLine(String.Join("-", jArray.Where(i => (int)i > 1).Select(i => i.ToString())));

Im using the following code in order to access generated find methods from my custom implementation. Getting the implementation through the bean factory prevents circular bean creation problems.

public class MyRepositoryImpl implements MyRepositoryExtensions, BeanFactoryAware {

    private BrandRepository myRepository;

    public MyBean findOne(int first, int second) {
        return myRepository.findOne(new Id(first, second));
    }

    public void setBeanFactory(BeanFactory beanFactory) throws BeansException {
        myRepository = beanFactory.getBean(MyRepository.class);
    }
}

In MySQL, the word 'type' is a Reserved Word.

Assuming you have the following database tables:

First, you need to create the @Embeddable holding the composite identifier:

@Embeddable
public class EmployeeId implements Serializable {
 
    @Column(name = "company_id")
    private Long companyId;
 
    @Column(name = "employee_number")
    private Long employeeNumber;
 
    public EmployeeId() {
    }
 
    public EmployeeId(Long companyId, Long employeeId) {
        this.companyId = companyId;
        this.employeeNumber = employeeId;
    }
 
    public Long getCompanyId() {
        return companyId;
    }
 
    public Long getEmployeeNumber() {
        return employeeNumber;
    }
 
    @Override
    public boolean equals(Object o) {
        if (this == o) return true;
        if (!(o instanceof EmployeeId)) return false;
        EmployeeId that = (EmployeeId) o;
        return Objects.equals(getCompanyId(), that.getCompanyId()) &&
                Objects.equals(getEmployeeNumber(), that.getEmployeeNumber());
    }
 
    @Override
    public int hashCode() {
        return Objects.hash(getCompanyId(), getEmployeeNumber());
    }
}

With this in place, we can map the Employee entity which uses the composite identifier by annotating it with @EmbeddedId:

@Entity(name = "Employee")
@Table(name = "employee")
public class Employee {
 
    @EmbeddedId
    private EmployeeId id;
 
    private String name;
 
    public EmployeeId getId() {
        return id;
    }
 
    public void setId(EmployeeId id) {
        this.id = id;
    }
 
    public String getName() {
        return name;
    }
 
    public void setName(String name) {
        this.name = name;
    }
}

The Phone entity which has a @ManyToOne association to Employee, needs to reference the composite identifier from the parent class via two @JoinColumnmappings:

@Entity(name = "Phone")
@Table(name = "phone")
public class Phone {
 
    @Id
    @Column(name = "`number`")
    private String number;
 
    @ManyToOne
    @JoinColumns({
        @JoinColumn(
            name = "company_id",
            referencedColumnName = "company_id"),
        @JoinColumn(
            name = "employee_number",
            referencedColumnName = "employee_number")
    })
    private Employee employee;
 
    public Employee getEmployee() {
        return employee;
    }
 
    public void setEmployee(Employee employee) {
        this.employee = employee;
    }
 
    public String getNumber() {
        return number;
    }
 
    public void setNumber(String number) {
        this.number = number;
    }
}

In A1 of your new sheet, put this:

=OFFSET(Sheet1!$A$1,(ROW()-1)*7,0)

... and copy down. If you start somewhere other than row 1, change ROW() to ROW(A1) or some other cell on row 1, then copy down again.

If you want to copy the nth line but multiple columns, use the formula:

=OFFSET(Sheet1!A$1,(ROW()-1)*7,0)

This can be copied right too.

document.getElementById("elementID").scrollHeight

$("elementID").scrollHeight

Oracle Database

ODD ROWS

select * from (select mod(rownum,2) as num , employees.* from employees) where num =0;

EVEN ROWS

select * from (select mod(rownum,2) as num , employees.* from employees) where num =1; 

I used below format

git push https://username:[email protected]/file.git --all

and if your password or username contain @ replace it with %40

For others having the same problem, try running

git add . which will add all files of the current directory to track (including untracked) and then use

git commit -a to commit all tracked files.

As suggested by @Pacerier, one liner that does the same thing is

git add -A

public String formatStr(float val) {
 return String.format(Locale.CANADA, "%,.2f", val);
}

formatStr(2524.2) // 2,254.20

If ANSI_NULLS is set to "ON" and if we apply = , <> on NULL column value while writing select statement then it will not return any result.

Example

create table #tempTable (sn int, ename varchar(50))

insert into #tempTable
values (1, 'Manoj'), (2, 'Pankaj'), (3, NULL), (4, 'Lokesh'), (5, 'Gopal')

SET ANSI_NULLS ON

select * from #tempTable where ename is NULL -- (1 row(s) affected)
select * from #tempTable where ename = NULL -- (0 row(s) affected)
select * from #tempTable where ename is not NULL -- (4 row(s) affected)
select * from #tempTable where ename <> NULL -- (0 row(s) affected)

SET ANSI_NULLS OFF

select * from #tempTable where ename is NULL -- (1 row(s) affected)
select * from #tempTable where ename = NULL -- (1 row(s) affected)
select * from #tempTable where ename is not NULL -- (4 row(s) affected)
select * from #tempTable where ename <> NULL -- (4 row(s) affected)

$firstname = $_POST["firstname"];
$lastname = $_POST["lastname"];
$email = $_POST["email"];
$pass = $_POST["password"];

$check_email = mysqli_query($conn, "SELECT Email FROM crud where Email = '$email' ");
if(mysqli_num_rows($check_email) > 0){
    echo('Email Already exists');
}
else{
    if ($_SERVER["REQUEST_METHOD"] == "POST") {
    $result = mysqli_query($conn, "INSERT INTO crud (Firstname, Lastname, Email, Password) VALUES ('$firstname', '$lastname', '$email', '$pass')");
}
    echo('Record Entered Successfully');
}

By converting the matrix to array by using

n12 = np.squeeze(np.asarray(n2))

X12 = np.squeeze(np.asarray(x1))

solved the issue.

Here is the Latest solution of the problem:

In your CSS file write the following class called .clearfix along with the pseudo selector :after

.clearfix:after {
content: "";
display: table;
clear: both;
}

Then, in your HTML, add the .clearfix class to your parent Div. For example:

<div class="clearfix">
    <div></div>
    <div></div>
</div>

It should work always. You can call the class name as .group instead of .clearfix , as it will make the code more semantic. Note that, it is Not necessary to add the dot or even a space in the value of Content between the double quotation "".

Here's how you do it in .NET, using S3 .NET SDK:

var client = new Amazon.S3.AmazonS3Client(_credentials, _config);
client.CopyObject(oldBucketName, oldfilepath, newBucketName, newFilePath);
client.DeleteObject(oldBucketName, oldfilepath);

P.S. try to use use "Async" versions of the client methods where possible, even though I haven't done so for readability

There is another solution for testing APIs on development server.

• Set HTTP Basic Authentication only for web routes
• Leave all API routes free from authentication

Web server configuration for nginx and Laravel would be like this:

    location /api {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location / {
        try_files $uri $uri/ /index.php?$query_string;

        auth_basic "Enter password";
        auth_basic_user_file /path/to/.htpasswd;
    }

Authorization: Bearer will do the job of defending the development server against web crawlers and other unwanted visitors.

I use these templates

template <typename T> string toStr(T tmp)
{
    ostringstream out;
    out << tmp;
    return out.str();
}


template <typename T> T strTo(string tmp)
{
    T output;
    istringstream in(tmp);
    in >> output;
    return output;
}

^[a-zA-Z] means any a-z or A-Z at the start of a line

[^a-zA-Z] means any character that IS NOT a-z OR A-Z

We could do without any xxxFactory, xxxManager or xxxRepository classes if we modeled the real world correctly:

Universe.Instance.Galaxies["Milky Way"].SolarSystems["Sol"]
        .Planets["Earth"].Inhabitants.OfType<Human>().WorkingFor["Initech, USA"]
        .OfType<User>().CreateNew("John Doe");

;-)

Use the css height and width properties.

For this to work on Mac, you also need to set the button's border to none.

I've used gFTP for that.

Tomcat 7 is BIO by default, although consensus seems to be "don't use Bio because Nio is better in every way". You set this using the protocol parameter in the server.xml file.

• BIO will be HTTP/1.1 or org.apache.coyote.http11.Http11Protocol
• NIO will be org.apache.coyote.http11.Http11NioProtocol

If you're using BIO then I believe they should be more or less the same.

If you're using NIO then actually "maxConnections=1000" and "maxThreads=10" might even be reasonable. The defaults are maxConnections=10,000 and maxThreads=200. With NIO, each thread can serve any number of connections, switching back and forth but retaining the connection so you don't need to do all the usual handshaking which is especially time-consuming with HTTPS but even an issue with HTTP. You can adjust the "keepAlive" parameter to keep connections around for longer and this should speed everything up.

The differences I could see is that Robocopy has a lot more options, but I didn't find any of them particularly helpful unless I'm doing something special.

I did some benchmarking of several copy routines and found XCOPY and ROBOCOPY to be the fastest, but to my surprise, XCOPY consistently edged out Robocopy.

It's ironic that robocopy retries a copy that fails, but it also failed a lot in my benchmark tests, where xcopy never did.

I did full file (byte by byte) file compares after my benchmark tests.

Here are the switches I used with robocopy in my tests:

 **"/E /R:1 /W:1 /NP /NFL /NDL"**.  

If anyone knows a faster combination (other than removing /E, which I need), I'd love to hear.

Another interesting/disappointing thing with robocopy is that if a copy does fail, by default it retries 1,000,000 times with a 30 second delay between each try. If you are running a long batch file unattended, you may be very disappointed when you come back after a few hours to find it's still trying to copy a particular file.

The /R and /W switches let you change this behavior.

• With /R you can tell it how many times to retry,
• /W let's you specify the wait time before retries.

If there's a way to attach files here, I can share my results.

• My tests were all done on the same computer and
• copied files from one external drive to another external,
• both on USB 3.0 ports.

I also included FastCopy and Windows Copy in my tests and each test was run 10 times. Note, the differences were pretty significant. The 95% confidence intervals had no overlap.

The two dots rule did not work for me. In my case I created a method to clean my resources as follows:

private static void Clean()
{
    workBook.Close();
    Marshall.ReleaseComObject(workBook);
    excel.Quit();
    CG.Collect();
    CG.WaitForPendingFinalizers();
}

the_int=window.clearInterval(the_int);

If your private method is not tested by calling your public methods then what is it doing? I'm talking private not protected or friend.

You can add a android:layoutAnimation="@anim/rv_item_animation" attribute to RecyclerView like this:

<android.support.v7.widget.RecyclerView
    android:layout_width="match_parent"
    android:layout_height="match_parent"                                        
    android:layoutAnimation="@anim/layout_animation_fall_down"
    />

It seems, that the simple way

-Dmaven.javadoc.skip=true

does not work with the release-plugin. in this case you have to pass the parameter as an "argument"

mvn release:perform -Darguments="-Dmaven.javadoc.skip=true"

Interesting approach could be found here: How To Enlarge Your Columns With No Downtime by spaghettidba

If you try to enlarge this column with a straight “ALTER TABLE” command, you will have to wait for SQLServer to go through all the rows and write the new data type

ALTER TABLE tab_name ALTER COLUMN col_name new_larger_data_type;

To overcome this inconvenience, there is a magic column enlargement pill that your table can take, and it’s called Row Compression. (...) With Row Compression, your fixed size columns can use only the space needed by the smallest data type where the actual data fits.

When table is compressed at ROW level, then ALTER TABLE ALTER COLUMN is metadata only operation.

This method uses the WindowOrWorkerGlobalScope.setInterval(https://developer.mozilla.org/en-US/doc) method to track the ready states of the document & see if the <body> element exists.

This pre-loading screen was made by Lapys @ https://github.com/LapysDev

Although Pascal's answer was detailed and informative it failed to mention some key information in the assumption that everyone knows how to use phpinfo()

For those that don't:

Navigate to your webservers root folder such as /var/www/

Within this folder create a text file called info.php

Edit the file and type phpinfo()

Navigate to the file such as: http://www.example.com/info.php

Here you will see the php.ini path under Loaded Configuration File:

Make sure you delete info.php when you are done.

Just clear the scope model value on click event and it should do the trick for you.

<input type="text" ng-model="searchAll" />
<a class="clear" ng-click="searchAll = null">
    <span class="glyphicon glyphicon-remove"></span>
</a>

Or if you keep your controller's $scope function and clear it from there. Make sure you've set your controller correctly.

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

There is a simple solution for you called unique_together which does exactly what you want.

For example:

class MyModel(models.Model):
  field1 = models.CharField(max_length=50)
  field2 = models.CharField(max_length=50)

  class Meta:
    unique_together = ('field1', 'field2',)

And in your case:

class Volume(models.Model):
  id = models.AutoField(primary_key=True)
  journal_id = models.ForeignKey(Journals, db_column='jid', null=True, verbose_name = "Journal")
  volume_number = models.CharField('Volume Number', max_length=100)
  comments = models.TextField('Comments', max_length=4000, blank=True)

  class Meta:
    unique_together = ('journal_id', 'volume_number',)

The answer is to use a JSONArray as well, and to dive "deep" into the tree structure:

JSONArray arr = new JSONArray();
arr.put (...); // a new JSONObject()
arr.put (...); // a new JSONObject()

JSONObject json = new JSONObject();
json.put ("aoColumnDefs",arr);

As of ES 7, mapping types have been removed. You can read more details here

If you are using Ruby On Rails this means that you may need to remove document_type from your model or concern.

As an alternative to mapping types one solution is to use an index per document type.

Before:

module Searchable
  extend ActiveSupport::Concern

  included do
    include Elasticsearch::Model
    include Elasticsearch::Model::Callbacks
    index_name [Rails.env, Rails.application.class.module_parent_name.underscore].join('_')
    document_type self.name.downcase
  end
end

After:

module Searchable
  extend ActiveSupport::Concern

  included do
    include Elasticsearch::Model
    include Elasticsearch::Model::Callbacks
    index_name [Rails.env, Rails.application.class.module_parent_name.underscore, self.name.downcase].join('_')
  end
end

The basic problem is, that you have to wait for the drawing phase for the actual measurements (especially with dynamic values like wrap_content or match_parent), but usually this phase hasn't been finished up to onResume(). So you need a workaround for waiting for this phase. There a are different possible solutions to this:

1. Listen to Draw/Layout Events: ViewTreeObserver

A ViewTreeObserver gets fired for different drawing events. Usually the OnGlobalLayoutListener is what you want for getting the measurement, so the code in the listener will be called after the layout phase, so the measurements are ready:

view.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {
                view.getViewTreeObserver().removeOnGlobalLayoutListener(this);
                view.getHeight(); //height is ready
            }
        });

Note: The listener will be immediately removed because otherwise it will fire on every layout event. If you have to support apps SDK Lvl < 16 use this to unregister the listener:

public void removeGlobalOnLayoutListener (ViewTreeObserver.OnGlobalLayoutListener victim)

2. Add a runnable to the layout queue: View.post()

Not very well known and my favourite solution. Basically just use the View's post method with your own runnable. This basically queues your code after the view's measure, layout, etc. as stated by Romain Guy:

The UI event queue will process events in order. After setContentView() is invoked, the event queue will contain a message asking for a relayout, so anything you post to the queue will happen after the layout pass

Example:

final View view=//smth;
...
view.post(new Runnable() {
            @Override
            public void run() {
                view.getHeight(); //height is ready
            }
        });

The advantage over ViewTreeObserver:

• your code is only executed once and you don't have to disable the Observer after execution which can be a hassle
• less verbose syntax

References:

• https://stackoverflow.com/a/3602144/774398
• https://stackoverflow.com/a/3948036/774398

3. Overwrite Views's onLayout Method

This is only practical in certain situation when the logic can be encapsulated in the view itself, otherwise this is a quite verbose and cumbersome syntax.

view = new View(this) {
    @Override
    protected void onLayout(boolean changed, int l, int t, int r, int b) {
        super.onLayout(changed, l, t, r, b);
        view.getHeight(); //height is ready
    }
};

Also mind, that onLayout will be called many times, so be considerate what you do in the method, or disable your code after the first time

4. Check if has been through layout phase

If you have code that is executing multiple times while creating the ui you could use the following support v4 lib method:

View viewYouNeedHeightFrom = ...
...
if(ViewCompat.isLaidOut(viewYouNeedHeightFrom)) {
   viewYouNeedHeightFrom.getHeight();
}

Returns true if view has been through at least one layout since it was last attached to or detached from a window.

Additional: Getting staticly defined measurements

If it suffices to just get the statically defined height/width, you can just do this with:

• View.getMeasuredWidth()
• View.getMeasuredHeigth()

But mind you, that this might be different to the actual width/height after drawing. The javadoc describes the difference in more detail:

The size of a view is expressed with a width and a height. A view actually possess two pairs of width and height values.

The first pair is known as measured width and measured height. These dimensions define how big a view wants to be within its parent (see Layout for more details.) The measured dimensions can be obtained by calling getMeasuredWidth() and getMeasuredHeight().

The second pair is simply known as width and height, or sometimes drawing width and drawing height. These dimensions define the actual size of the view on screen, at drawing time and after layout. These values may, but do not have to, be different from the measured width and height. The width and height can be obtained by calling getWidth() and getHeight().

I had this issue today and replace / trim did the trick..see below.

update table_foo 
set column_bar  = REPLACE(LTRIM(RTRIM(column_bar)), '  ', '')

before and after :

old-bad:  column_bar    |   New-fixed:   column_bar
       '  xyz  '        |                'xyz'   
       '  xyz  '        |                'xyz' 
       '  xyz  '        |                'xyz' 
       '  xyz  '        |                'xyz' 
       '  xyz  '        |                'xyz' 
       '  xyz  '        |                'xyz' 

Here is a non-jquery way to monitor events in the console with your code and without the use of monitorEvents() because that only works in Chrome Developer Console. You can also choose to not monitor certain events by editing the no_watch array.

    function getEvents(obj) {
    window["events_list"] = [];
    var no_watch = ['mouse', 'pointer']; // Array of event types not to watch
    var no_watch_reg = new RegExp(no_watch.join("|"));

    for (var prop in obj) {
        if (prop.indexOf("on") === 0) {
            prop = prop.substring(2); // remove "on" from beginning
            if (!prop.match(no_watch_reg)) {
                window["events_list"].push(prop);
                window.addEventListener(prop, function() {
                    console.log(this.event); // Display fired event in console
                } , false);
            }
        }
    }
    window["events_list"].sort(); // Alphabetical order 

}

getEvents(document); // Put window, document or any html element here
console.log(events_list); // List every event on element

I have a couple of turn-based games where I need the AI to pause before taking its turn (and between steps in its turn). I'm sure there are other, more useful, situations where a delay is the best solution. In Swift:

        let delay = 2.0 * Double(NSEC_PER_SEC) 
        let time = dispatch_time(DISPATCH_TIME_NOW, Int64(delay)) 
        dispatch_after(time, dispatch_get_main_queue()) { self.playerTapped(aiPlayView) }

I just came back here to see if the Objective-C calls were different.(I need to add this to that one, too.)

When loading a resource make sure you notice the difference between:

getClass().getClassLoader().getResource("com/myorg/foo.jpg") //relative path

and

getClass().getResource("/com/myorg/foo.jpg")); //note the slash at the beginning

I guess, this confusion is causing most of problems when loading a resource.

Also, when you're loading an image it's easier to use getResourceAsStream():

BufferedImage image = ImageIO.read(getClass().getResourceAsStream("/com/myorg/foo.jpg"));

When you really have to load a (non-image) file from a JAR archive, you might try this:

File file = null;
String resource = "/com/myorg/foo.xml";
URL res = getClass().getResource(resource);
if (res.getProtocol().equals("jar")) {
    try {
        InputStream input = getClass().getResourceAsStream(resource);
        file = File.createTempFile("tempfile", ".tmp");
        OutputStream out = new FileOutputStream(file);
        int read;
        byte[] bytes = new byte[1024];

        while ((read = input.read(bytes)) != -1) {
            out.write(bytes, 0, read);
        }

        file.deleteOnExit();
    } catch (IOException ex) {
        Exceptions.printStackTrace(ex);
    }
} else {
    //this will probably work in your IDE, but not from a JAR

select fields 
from tableA --left
left join tableB --right
on tableA.key = tableB.key

The table in the from in this example tableA, is on the left side of relation.

tableA <- tableB
[left]------[right]

So if you want to take all rows from the left table (tableA), even if there are no matches in the right table (tableB), you'll use the "left join".

And if you want to take all rows from the right table (tableB), even if there are no matches in the left table (tableA), you will use the right join.

Thus, the following query is equivalent to that used above.

select fields
from tableB 
right join tableA on tableB.key = tableA.key

Searching for created_at <= '2011-12-06' will search for any records that where created at or before midnight on 2011-12-06 . You want to search for created_at < '2011-12-07'.

jQuery (1.4.2) gets confused if you have any form elements named "action". You can get around this by using the DOM attribute methods or simply avoid having form elements named "action".

<form action="foo">
  <button name="action" value="bar">Go</button>
</form>

<script type="text/javascript">
  $('form').attr('action', 'baz'); //this fails silently
  $('form').get(0).setAttribute('action', 'baz'); //this works
</script>

Here's another approach that takes advantage of Matlab's strjoin function. With strjoin it's easy to customize the delimiter between values.

x = [1, 2, 3];
fprintf('Answer: (%s)\n', strjoin(cellstr(num2str(x(:))),', '));

This results in: Answer: (1, 2, 3)

You can use the below syntax -

from FolderName.FileName import Classname

Not append() but appends() So, right answer is:

{!! $records->appends(Input::except('page'))->links() !!}

Here's something I've just knocked up. It inspects the environment of the last-launched "gnome-session" process (DISPLAY is set correctly when VNC launches a session/window manager). Replace "gnome-session" with the name of whatever process your VNC server launches on startup.

PID=`pgrep -n -u $USER gnome-session`
if [ -n "$PID" ]; then
    export DISPLAY=`awk 'BEGIN{FS="="; RS="\0"}  $1=="DISPLAY" {print $2; exit}' /proc/$PID/environ`
    echo "DISPLAY set to $DISPLAY"
else
    echo "Could not set DISPLAY"
fi
unset PID

You should just be able to drop that in your .bashrc file.

You can also configure m2e to use HTTP instead of HTTPS

Recently, when I was dealing with an AJAX application/RIA, I was having the same issue! And I used implicit wait, with a time of around 90 seconds. It waits, till the element is available...So, what we can do to make sure, that page gets loaded completely is,

add a boolean statement, checking for whether the condition(a particular part of the element), is present and assign it to a variable, check for the condition and only when it is true, " do the necessary actions!"...In this way, I figured out, both waits could be used...

Ex:

@Before

{ implicit wait statement}

@Test

{

boolean tr1=Driver.findElement(By.xpath("xx")).isEnabled/isDisplayed;

if (tr1==true && ____)//as many conditions, to make sure, the page is loaded

{

//do the necessary set of actions...
driver.findElement(By.xpath("yy")).click();

}

}

Hope this helps!! It is in implementation stage, for me too...

Use android:textStyle="bold"

4 ways to make Android TextView Bold

like this

<TextView
android:layout_height="wrap_content"
android:layout_width="wrap_content"
android:textSize="12dip"
android:textStyle="bold"
/>

There are many ways to make Android TextView bold.

Options -Indexes returns a 403 forbidden error for a protected directory. The same behaviour can be achived by using the following Redirect in htaccess :

RedirectMatch 403 ^/folder/?$ 

This will return a forbidden error for example.com/folder/ .

You can also use mod-rewrite to forbid a request for folder.

RewriteEngine on

RewriteRule ^folder/?$ - [F]

If your htaccess is in the folder that you are going to forbid , change RewriteRule's pattern from ^folder/?$ to ^$ .

You could also do the following:

// untested
Calendar cal = GregorianCalendar.getInstance();
cal.set(Calendar.DAY_OF_MONTH, 23);// I might have the wrong Calendar constant...
cal.set(Calendar.MONTH, 8);// -1 as month is zero-based
cal.set(Calendar.YEAR, 2009);
Timestamp tstamp = new Timestamp(cal.getTimeInMillis());

For loading weights, you need to have a model first. It must be:

existingModel.save_weights('weightsfile.h5')
existingModel.load_weights('weightsfile.h5')     

If you want to save and load the entire model (this includes the model's configuration, it's weights and the optimizer states for further training):

model.save_model('filename')
model = load_model('filename')

I am facing the same issue on Xcode 7.3 and my device version is iOS 10.

This error is shown when your Xcode is old and the related device you are using is updated to latest version. First of all, install the latest Xcode version.

We can solve this issue by following the below steps:-

• Open Finder select Applications
• Right click on Xcode 8, select "Show Package Contents", "Contents", "Developer", "Platforms", "iPhoneOS.Platform", "Device Support"
• Copy the 10.0 folder (or above for later version).
• Back in Finder select Applications again
• Right click on Xcode 7.3, select "Show Package Contents", "Contents", "Developer", "Platforms", "iPhoneOS.Platform", "Device Support"
• Paste the 10.0 folder

If everything worked properly, your Xcode has a new developer disk image. Close the finder now, and quit your Xcode. Open your Xcode and the error will be gone. Now you can connect your latest device to old Xcode versions.

Thanks

This issue can also occur when you pull code from git and not yet installed node modules "npm install".

At every step, there are two cases

b >= a / 2, then a, b = b, a % b will make b at most half of its previous value

b < a / 2, then a, b = b, a % b will make a at most half of its previous value, since b is less than a / 2

So at every step, the algorithm will reduce at least one number to at least half less.

In at most O(log a)+O(log b) step, this will be reduced to the simple cases. Which yield an O(log n) algorithm, where n is the upper limit of a and b.

I have found it here

You could make use of Prepared Stements like this.

set @query = concat( "select name from " );
set @query = concat( "table_name"," [where condition] " );

prepare stmt from @like_q;
execute stmt;

Check out fontsquirrel. They have a web font generator, which will also spit out a suitable stylesheet for your font (look for "@font-face kit"). This stylesheet can be included in your own, or you can use it as a template.

As TokenMacGuy says, you should use thread.is_alive() to check if a thread is still running. To remove no longer running threads from your list you can use a list comprehension:

for t in my_threads:
    if not t.is_alive():
        # get results from thread
        t.handled = True
my_threads = [t for t in my_threads if not t.handled]

This avoids the problem of removing items from a list while iterating over it.

After few years, I moved to leaflet map and I have fixed this issue completely, the following could be applied to google maps too:

    var headerHeight = $("#navMap").outerHeight();
    var footerHeight = $("footer").outerHeight();
    var windowHeight = window.innerHeight;
    var mapContainerHeight = headerHeight + footerHeight;
    var totalMapHeight = windowHeight - mapContainerHeight;
    $("#map").css("margin-top", headerHeight);
    $("#map").height(totalMapHeight);

    $(window).resize(function(){
        var headerHeight = $("#navMap").outerHeight();
        var footerHeight = $("footer").outerHeight();
        var windowHeight = window.innerHeight;
        var mapContainerHeight = headerHeight + footerHeight;
        var totalMapHeight = windowHeight - mapContainerHeight;
        $("#map").css("margin-top", headerHeight);
        $("#map").height(totalMapHeight);
        map.fitBounds(group1.getBounds());
    });

1. Installing OpenCV 2.4.3

First, get OpenCV 2.4.3 from sourceforge.net. Its a self-extracting so just double click to start the installation. Install it in a directory, say C:\.

Wait until all files get extracted. It will create a new directory C:\opencv which contains OpenCV header files, libraries, code samples, etc.

Now you need to add the directory C:\opencv\build\x86\vc10\bin to your system PATH. This directory contains OpenCV DLLs required for running your code.

Open Control Panel → System → Advanced system settings → Advanced Tab → Environment variables...

On the System Variables section, select Path (1), Edit (2), and type C:\opencv\build\x86\vc10\bin; (3), then click Ok.

On some computers, you may need to restart your computer for the system to recognize the environment path variables.

This will completes the OpenCV 2.4.3 installation on your computer.

2. Create a new project and set up Visual C++

Open Visual C++ and select File → New → Project... → Visual C++ → Empty Project. Give a name for your project (e.g: cvtest) and set the project location (e.g: c:\projects).

Click Ok. Visual C++ will create an empty project.

Make sure that "Debug" is selected in the solution configuration combobox. Right-click cvtest and select Properties → VC++ Directories.

Select Include Directories to add a new entry and type C:\opencv\build\include.

Click Ok to close the dialog.

Back to the Property dialog, select Library Directories to add a new entry and type C:\opencv\build\x86\vc10\lib.

Click Ok to close the dialog.

Back to the property dialog, select Linker → Input → Additional Dependencies to add new entries. On the popup dialog, type the files below:

opencv_calib3d243d.lib
opencv_contrib243d.lib
opencv_core243d.lib
opencv_features2d243d.lib
opencv_flann243d.lib
opencv_gpu243d.lib
opencv_haartraining_engined.lib
opencv_highgui243d.lib
opencv_imgproc243d.lib
opencv_legacy243d.lib
opencv_ml243d.lib
opencv_nonfree243d.lib
opencv_objdetect243d.lib
opencv_photo243d.lib
opencv_stitching243d.lib
opencv_ts243d.lib
opencv_video243d.lib
opencv_videostab243d.lib

Note that the filenames end with "d" (for "debug"). Also note that if you have installed another version of OpenCV (say 2.4.9) these filenames will end with 249d instead of 243d (opencv_core249d.lib..etc).

Click Ok to close the dialog. Click Ok on the project properties dialog to save all settings.

NOTE:

These steps will configure Visual C++ for the "Debug" solution. For "Release" solution (optional), you need to repeat adding the OpenCV directories and in Additional Dependencies section, use:

opencv_core243.lib
opencv_imgproc243.lib
...

instead of:

opencv_core243d.lib
opencv_imgproc243d.lib
...

You've done setting up Visual C++, now is the time to write the real code. Right click your project and select Add → New Item... → Visual C++ → C++ File.

Name your file (e.g: loadimg.cpp) and click Ok. Type the code below in the editor:

#include <opencv2/highgui/highgui.hpp>
#include <iostream>

using namespace cv;
using namespace std;

int main()
{
    Mat im = imread("c:/full/path/to/lena.jpg");
    if (im.empty()) 
    {
        cout << "Cannot load image!" << endl;
        return -1;
    }
    imshow("Image", im);
    waitKey(0);
}

The code above will load c:\full\path\to\lena.jpg and display the image. You can use any image you like, just make sure the path to the image is correct.

Type F5 to compile the code, and it will display the image in a nice window.

And that is your first OpenCV program!

3. Where to go from here?

Now that your OpenCV environment is ready, what's next?

1. Go to the samples dir → c:\opencv\samples\cpp.
2. Read and compile some code.
3. Write your own code.

I had the same issue with numeral, a JS library. The fix was to install the typings again with this command:

npm install --save @types/numeral

With:

FILES = $(shell ls)

indented underneath all like that, it's a build command. So this expands $(shell ls), then tries to run the command FILES ....

If FILES is supposed to be a make variable, these variables need to be assigned outside the recipe portion, e.g.:

FILES = $(shell ls)
all:
        echo $(FILES)

Of course, that means that FILES will be set to "output from ls" before running any of the commands that create the .tgz files. (Though as Kaz notes the variable is re-expanded each time, so eventually it will include the .tgz files; some make variants have FILES := ... to avoid this, for efficiency and/or correctness.¹)

If FILES is supposed to be a shell variable, you can set it but you need to do it in shell-ese, with no spaces, and quoted:

all:
        FILES="$(shell ls)"

However, each line is run by a separate shell, so this variable will not survive to the next line, so you must then use it immediately:

        FILES="$(shell ls)"; echo $$FILES

This is all a bit silly since the shell will expand * (and other shell glob expressions) for you in the first place, so you can just:

        echo *

as your shell command.

Finally, as a general rule (not really applicable to this example): as esperanto notes in comments, using the output from ls is not completely reliable (some details depend on file names and sometimes even the version of ls; some versions of ls attempt to sanitize output in some cases). Thus, as l0b0 and idelic note, if you're using GNU make you can use $(wildcard) and $(subst ...) to accomplish everything inside make itself (avoiding any "weird characters in file name" issues). (In sh scripts, including the recipe portion of makefiles, another method is to use find ... -print0 | xargs -0 to avoid tripping over blanks, newlines, control characters, and so on.)

¹The GNU Make documentation notes further that POSIX make added ::= assignment in 2012. I have not found a quick reference link to a POSIX document for this, nor do I know off-hand which make variants support ::= assignment, although GNU make does today, with the same meaning as :=, i.e., do the assignment right now with expansion.

Note that VAR := $(shell command args...) can also be spelled VAR != command args... in several make variants, including all modern GNU and BSD variants as far as I know. These other variants do not have $(shell) so using VAR != command args... is superior in both being shorter and working in more variants.

=IF(CR<=10, "RED", if(CR<50, "YELLOW", if(CR<101, "GREEN")))

CR = ColRow (Cell) This is an example. In this example when value in Cell is less then or equal to 10 then RED word will appear on that cell. In the same manner other if conditions are true if first if is false.

For this you can simply use the "HttpWebRequest" and "HttpWebResponse" classes in .net.

Below is a sample console app I wrote to demonstrate how easy this is.

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            string url = "www.somewhere.com";       
            string fileName = @"C:\output.file";

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Timeout = 5000;

            try
            {
                using (WebResponse response = (HttpWebResponse)request.GetResponse())
                {
                    using (FileStream stream = new FileStream(fileName, FileMode.Create, FileAccess.Write))
                    {
                        byte[] bytes = ReadFully(response.GetResponseStream());

                        stream.Write(bytes, 0, bytes.Length);
                    }
                }
            }
            catch (WebException)
            {
                Console.WriteLine("Error Occured");
            }
        }

        public static byte[] ReadFully(Stream input)
        {
            byte[] buffer = new byte[16 * 1024];
            using (MemoryStream ms = new MemoryStream())
            {
                int read;
                while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
                {
                    ms.Write(buffer, 0, read);
                }
                return ms.ToArray();
            }
        }
    }
}

Enjoy!

I've had a similar issue with 1.7.2 versions of jQuery and jQuery UI. The popup wasn't showing up and none of the applicable suggestions above helped. What helped in my case was taking out the class="hasDatepicker" which (as the accepted answer here notes: jQuery UI datepicker will not display - full code included) is used by jquery-ui to indicate that a datepicker has already been added to the text field. Wish I found that answer sooner.

Using Typescript 3.6.3, and Angular 6, none of these solutions worked for me.

What did work was to follow the tutorial here which says you need to add a small file called njson-typings.d.ts to your project, containing this:

declare module "*.json" {
  const value: any;
  export default value;
}

Once this was done, I could simply import my hardcoded json data:

import employeeData from '../../assets/employees.json';

and use it in my component:

export class FetchDataComponent implements OnInit {
  public employees: Employee[];

  constructor() {
    //  Load the data from a hardcoded .json file
    this.employees = employeeData;
    . . . .
  }

I have routine in VB ..

but you should have 2 pictureboxes .. 1 for frame .. 1 for the image .. and it make keep the picture's size ratio

Assumed picFrame is the image frame and picImg is the image

Sub InsertPicture(ByVal oImg As Image)
    Dim oFoto As Image
    Dim x, y As Integer

    oFoto = oImg
    picImg.Visible = False
    picImg.Width = picFrame.Width - 2
    picImg.Height = picFrame.Height - 2
    picImg.Location = New Point(1, 1)
    SetPicture(picPreview, oFoto)
    x = (picImg.Width - picFrame.Width) / 2
    y = (picImg.Height - picFrame.Height) / 2
    picImg.Location = New Point(x, y)
    picImg.Visible = True

End Sub

I'm sure you can make it as C# ....

A statement contains a keyword.

An expression does not contain a keyword.

print "hello" is statement, because print is a keyword.

"hello" is an expression, but list compression is against this.

The following is an expression statement, and it is true without list comprehension:

(x*2 for x in range(10))

This is how I count TABLES and ALL RECORDS using PHP:

$dtb = mysql_query("SHOW TABLES") or die (mysql_error());
$jmltbl = 0;
$jml_record = 0;
$jml_record = 0;

while ($row = mysql_fetch_array($dtb)) { 
    $sql1 = mysql_query("SELECT * FROM " . $row[0]);            
    $jml_record = mysql_num_rows($sql1);            
    echo "Table: " . $row[0] . ": " . $jml_record record . "<br>";      
    $jmltbl++;
    $jml_record += $jml_record;
}

echo "--------------------------------<br>$jmltbl Tables, $jml_record > records.";

I have a simple example to show how to do angular 2 rc6 dynamic component.

Say, you have a dynamic html template = template1 and want to dynamic load, firstly wrap into component

@Component({template: template1})
class DynamicComponent {}

here template1 as html, may be contains ng2 component

From rc6, have to have @NgModule wrap this component. @NgModule, just like module in anglarJS 1, it decouple different part of ng2 application, so:

@Component({
  template: template1,

})
class DynamicComponent {

}
@NgModule({
  imports: [BrowserModule,RouterModule],
  declarations: [DynamicComponent]
})
class DynamicModule { }

(Here import RouterModule as in my example there is some route components in my html as you can see later on)

Now you can compile DynamicModule as: this.compiler.compileModuleAndAllComponentsAsync(DynamicModule).then( factory => factory.componentFactories.find(x => x.componentType === DynamicComponent))

And we need put above in app.moudule.ts to load it, please see my app.moudle.ts. For more and full details check: https://github.com/Longfld/DynamicalRouter/blob/master/app/MyRouterLink.ts and app.moudle.ts

and see demo: http://plnkr.co/edit/1fdAYP5PAbiHdJfTKgWo?p=preview

The usual command line ping tool uses ICMP Echo, but it's true that other protocols can also be used, and they're useful in debugging different kinds of network problems.

I can remember at least arping (for testing ARP requests) and tcping (which tries to establish a TCP connection and immediately closes it, it can be used to check if traffic reaches a certain port on a host) off the top of my head, but I'm sure there are others aswell.

Simply put:

.democlass {
    background-color: rgba(246,245,245,0);
}

That should give you a transparent background.

I would use something like this:

String.format("%tF %<tT.%<tL", dateTime);

Variable dateTime could be any date and/or time value, see JavaDoc for Formatter.

There is also logging.exception.

import logging

...

try:
    g()
except Exception as ex:
    logging.exception("Something awful happened!")
    # will print this message followed by traceback

Output:

I had trouble deleting a cookie made via JavaScript and after I added the host it worked (scroll the code below to the right to see the location.host). After clearing the cookies on a domain try the following to see the results:

if (document.cookie.length==0)
{
 document.cookie = 'name=example; expires='+new Date((new Date()).valueOf()+1000*60*60*24*15)+'; path=/; domain='+location.host;

 if (document.cookie.length==0) {alert('Cookies disabled');}
 else
 {
  document.cookie = 'name=example; expires=Thu, 01 Jan 1970 00:00:00 GMT; path=/; domain='+location.host;

  if (document.cookie.length==0) {alert('Created AND deleted cookie successfully.');}
  else {alert('document.cookies.length = '+document.cookies.length);}
 }
}

It's not the best answer, but its also an option: since you can concatenate multiple expressions, but just the last one is rendered, you can finish your expression with "" and your variable will be hidden.

So, you could define the variable with:

{{f = forecast[day.iso]; ""}}

Reading answers here, it seems that the error "RenderBox was not laid out" is caused when somehow the ListView size is limitless and this can happen in different scenarios.

Just aiming to help who may have the same case as mine. In my case, I was getting this error because my ListView was inside a a column whose parent was a SingleChildScrollView. I remove this parent and it worked.

Here is my working code:

 List _todoList = ["AAA", "BBB"];

 ...

    body: Column(
      children: [
        Container(...),
        Expanded(
            child: ListView.builder(
                itemCount: _todoList.length,
                itemBuilder: (context, index) {
                  return ListTile(title: Text(_todoList[index]));
                }))
      ],
    ));

Here how it was when I was getting the "not laid out" error:

     List _todoList = ["AAA", "BBB"];

     ...


     body: SingleChildScrollView(child: Column(
      children: [
        Container(...),
        Expanded(
            child: ListView.builder(
                itemCount: _todoList.length,
                itemBuilder: (context, index) {
                  return ListTile(title: Text(_todoList[index]));
                }))
      ],
    )));

I hope this may be useful for someone.

See Creating a shared and static library with the gnu compiler [gcc]

gcc -c -o out.o out.c

-c means to create an intermediary object file, rather than an executable.

ar rcs libout.a out.o

This creates the static library. r means to insert with replacement, c means to create a new archive, and s means to write an index. As always, see the man page for more info.

Paths specified with a . are relative to the current working directory, not relative to the script file. So the file might be found if you run node app.js but not if you run node folder/app.js. The only exception to this is require('./file') and that is only possible because require exists per-module and thus knows what module it is being called from.

To make a path relative to the script, you must use the __dirname variable.

var path = require('path');

path.join(__dirname, 'path/to/file')

or potentially

path.join(__dirname, 'path', 'to', 'file')

Use the SQLite keyword default

cd /var/log/mysql

and lastly type: > mysql-slow.log

This worked for me

.highlight { background-color: red; }

If you want multiple selections

$("#data tr").click(function() {
    $(this).toggleClass("highlight");
});

If you want only 1 row in the table to be selected at a time

$("#data tr").click(function() {
    var selected = $(this).hasClass("highlight");
    $("#data tr").removeClass("highlight");
    if(!selected)
            $(this).addClass("highlight");
});

Also note your TABLE tag has 2 ID attributes, you can't do that.

You should be able to use the "ours" merge strategy to overwrite master with seotweaks like this:

git checkout seotweaks
git merge -s ours master
git checkout master
git merge seotweaks

The result should be your master is now essentially seotweaks.

(-s ours is short for --strategy=ours)

From the docs about the 'ours' strategy:

This resolves any number of heads, but the resulting tree of the merge is always that of the current branch head, effectively ignoring all changes from all other branches. It is meant to be used to supersede old development history of side branches. Note that this is different from the -Xours option to the recursive merge strategy.

Update from comments: If you get fatal: refusing to merge unrelated histories, then change the second line to this: git merge --allow-unrelated-histories -s ours master

I had a different use case, I want different formats based how long between start and end time of data in graph. I found this to be simplest approach

    xAxes = {
        type: "time",
        time: {
            displayFormats: {
                hour: "hA"
            }
        },
        display: true,
        ticks: {
            reverse: true
        },
        gridLines: {display: false}
    }
    // if more than two days between start and end of data,  set format to show date,  not hrs
    if ((parseInt(Cookies.get("epoch_max")) - parseInt(Cookies.get("epoch_min"))) > (1000*60*60*24*2)) {
        xAxes.time.displayFormats.hour = "MMM D";
    }

To use PSCP, you need the private key you generated in Converting Your Private Key Using PuTTYgen. You also need the public DNS address of your Linux instance

pscp -i C:\path\my-key-pair.ppk C:\path\Sample_file.txt ec2-user@public_dns:/home/ec2-user/Sample_file.txt

The below method to migrate my GIT Stash to GitLab by maintaining all branches and preserving history.

Clone the old repository to local.

git clone --bare <STASH-URL>

Create an empty repository in GitLab.

git push --mirror <GitLab-URL>

The above I performed when we migrated our code from stash to GitLab and it worked very well.

I had the same problem. I changed the Version of Assembly in AssemblyInfo.cs in the Properties Folder. But, I don't have any idea why this problem happened. Maybe the compiler doesn't understand that this dll is newer, just changing the version of Assembly.

Why not so?:

set host=%COMPUTERNAME%
echo %host%

I used DecimalFormat for formatting the BigDecimal instead of formatting the String, seems no problems with it.

The code is something like this:

bd = bd.setScale(2, BigDecimal.ROUND_DOWN);

DecimalFormat df = new DecimalFormat();

df.setMaximumFractionDigits(2);

df.setMinimumFractionDigits(0);

df.setGroupingUsed(false);

String result = df.format(bd);

string strvalue="11".PadRight(4, '0');

output= 1100

string strvalue="301".PadRight(4, '0');

output= 3010

string strvalue="11".PadLeft(4, '0');

output= 0011

string strvalue="301".PadLeft(4, '0');

output= 0301

Set the max allowed packet size using MySql Workbench and restart the server

One way to speed things up is to explicitly perform multiple inserts or copy's within a transaction (say 1000). Postgres's default behavior is to commit after each statement, so by batching the commits, you can avoid some overhead. As the guide in Daniel's answer says, you may have to disable autocommit for this to work. Also note the comment at the bottom that suggests increasing the size of the wal_buffers to 16 MB may also help.

./gradlew

Your directory with gradlew is not included in the PATH, so you must specify path to the gradlew. . means "current directory".

$("#select-id").chosen().val()

Unfortunately stringification can not always be used as commenting out! So it is safer to stick to the standard prepending each line with a #.

Here is an example:

test1 = [1, 2, 3, 4,]       # test1 contains 4 integers

test2 = [1, 2, '''3, 4,'''] # test2 contains 2 integers **and the string** '3, 4,'

You can use NPOI to do it.

Workbook wb = new HSSFWorkbook();
Sheet sheet = wb.createSheet("new sheet");

Row row = sheet.createRow((short) 1);
Cell cell = row.createCell((short) 1);
cell.setCellValue("This is a test of merging");

sheet.addMergedRegion(new CellRangeAddress(
        1, //first row (0-based)
        1, //last row  (0-based)
        1, //first column (0-based)
        2  //last column  (0-based)
));

// Write the output to a file
FileOutputStream fileOut = new FileOutputStream("workbook.xls");
wb.write(fileOut);
fileOut.close();

I think this is what you are looking for: jquery-html5-placeholder-fix

This solution uses feature detection (via modernizr) to determine if placeholder is supported. If not, adds support (via jQuery).

I just did the following (in V 3.5) and it worked like a charm:

<p:column headerText="name" width="20px"/>

Seems none of above solutions are actually working. The --disable-web-security is no longer supported in recent chrome versions.

Allow-Control-Allow-Origin: * - chrome extension partially solved the problem. It works only if your request is using GET method and there's no custom HTTP Header. Otherwise, chrome will send OPTIONS HTTP request as a pre-flight request. If the server doesn't support CORS, it will respond with 404 HTTP status code. The plugin can't modify the response HTTP status code. So chrome will reject this request. There's no way for chrome plugin to modify the response HTTP status code based on current chrome extension API. And you can't do a redirect as well for XHR initiated request.

Not sure why Chrome makes developers life so difficult. It blocks all the possible ways to disable XSS security check even for development use which is totally unnecessary.

After days struggle and research, one solution works perfectly for me: to use corsproxy. You have two options here: 1. use [https://cors-anywhere.herokuapp.com/] 2. install corsproxy in the local box: npm install -g corsproxy

[Updated on Jun 23, 2018] Recent I'm developing an SPA app which need to use corsproxy again. But seem none of the corsproxy on the github can meet my requirement.

• need it to run inside firewall for security reason. So I can't use https://cors-anywhere.herokuapp.com/.
• It has to support https as chrome will block no-https ajax request in an https page.
• I need to run on nodejs. I don't want to maintain another language stack.

So I decide to develop my own version of corsproxy with nodejs. It's actually very simple. I have published it as a gist on the github. Here is the source code gist: https://gist.github.com/jianwu/8e76eaec95d9b1300c59596fbfc21b10

• It's in plain nodejs code without any additional dependencies
• You can run in http and https mode (by passing the https port number in command line), to run https, you need to generate cert and key and put them in the webroot directory.
• It also serves as static file server
• It supports pre-flight OPTION request as well.

To start the CORSProxy server (http port 8080): node static_server.js 8080

to access the proxy: http://host:8080/http://www.somesite.com

In JavaScript, strings are immutable, which means the best you can do is to create a new string with the changed content and assign the variable to point to it.

You'll need to define the replaceAt() function yourself:

String.prototype.replaceAt = function(index, replacement) {
    return this.substr(0, index) + replacement + this.substr(index + replacement.length);
}

And use it like this:

var hello = "Hello World";
alert(hello.replaceAt(2, "!!")); // Should display He!!o World

You should try this one:

Console.WriteLine("{0}.{1}.{2}", mon, da, yet);

See http://www.dotnetperls.com/console-writeline for more details.

cp -Rvn /source/path/* /destination/path/
cp: /destination/path/any.zip: No such file or directory

It will create no existing paths in destination, if path have a source file inside. This dont create empty directories.

A moment ago i've seen xxxxxxxx: No such file or directory, because i run out of free space. without error message.

with ditto:

ditto -V /source/path/* /destination/path
ditto: /destination/path/any.zip: No space left on device

once freed space cp -Rvn /source/path/* /destination/path/ works as expected

It sounds like you're going to have to create a new project in Xcode, go into the old directory, and drag all your source files, nibs, and resources into the Xcode files sidebar in the new project. It shouldn't take more than a few minutes, unless you really did a lot of work with custom build settings or targets. Either that, or revert to the last check-in in your source control and manually add any code files which changed between now and then.

To display the current system date in oracle-sql

   select sysdate from dual;

Perl solution similar to Mat's awk solution:

perl -F'\|' -lane 'print $#F+1; exit' stores.dat

I've tested this on a file with 1000000 columns.

If the field separator is whitespace (one or more spaces or tabs) instead of a pipe:

perl -lane 'print $#F+1; exit' stores.dat

Consider also this:

git range-diff tagA...tagB

I was missing several DLLs. Even if I manually copied them to the directory the next time I published they would disappear. Each one was already set to Copy Locally in VS. The fix for me was to set each one to Copy Locally false, save, build then set each one to copy locally true. This time when I published all of the DLLs published correctly. Strange

This fixed the same issue for me: My eclipse is installed in /usr/local/bin/eclipse

1) Changed permission for eclipse from root to owner: sudo chown -R $USER eclipse

2) Right click on project/Maven right click on Update Maven select Force update maven project

To add an exclusion for logback from Netbeans IDE

1. Access the >Projects explorer section for your project
2. Proceed to >Dependencies as displayed below
3. Trace 'spring-boot-starter-logging-X.X.X.jar'

4. Right click on the jar and select Exclude Dependency as shown below. This excludes the logback jar on the pom.xml like this;

     <dependency>
       <groupId>org.springframework.boot</groupId>
       <artifactId>spring-boot-starter-web</artifactId>
       <exclusions>
           <exclusion>
               <groupId>org.springframework.boot</groupId>
               <artifactId>spring-boot-starter-logging</artifactId>
           </exclusion>
       </exclusions>
   </dependency>
   

You can use fprintf/sprintf with familiar C syntax. Maybe something like:

fprintf('x = %d, y = %d \n x+y=%d \n x*y=%d \n x/y=%f\n', x,y,d,e,f)

reading your comment, this is how you use your functions from the main program:

x = 2;
y = 2;
[d e f] = answer(x,y);
fprintf('%d + %d = %d\n', x,y,d)
fprintf('%d * %d = %d\n', x,y,e)
fprintf('%d / %d = %f\n', x,y,f)

Also for the answer() function, you can assign the output values to a vector instead of three distinct variables:

function result=answer(x,y)
result(1)=addxy(x,y);
result(2)=mxy(x,y);
result(3)=dxy(x,y);

and call it simply as:

out = answer(x,y);

.close() is mor general and can be used in reference to more objects. .dialog('close') can only be used with dialogs

There is a tiny drop-in replacement for the standard android Log class - https://github.com/zserge/log

Basically all you have to do is to replace imports from android.util.Log to trikita.log.Log. Then in your Application.onCreate() or in some static initalizer check for the BuilConfig.DEBUG or any other flag and use Log.level(Log.D) or Log.level(Log.E) to change the minimal log level. You can use Log.useLog(false) to disable logging at all.

It's not 100% clear from the code example, but if the list initial_parameters_of_hypothesis_function is a list of tf.Variable objects, then the line session.run(init) will fail because TensorFlow isn't (yet) smart enough to figure out the dependencies in variable initialization. To work around this, you should change the loop that creates parameters to use initial_parameters_of_hypothesis_function[i].initialized_value(), which adds the necessary dependency:

parameters = []
for i in range(0, number_of_attributes, 1):
    parameters.append(tf.Variable(
        initial_parameters_of_hypothesis_function[i].initialized_value()))

Here's a short example, that creates and array of objects, and sorts numerically or alphabetically:

// Create Objects Array

var arrayCarObjects = [
{brand: "Honda",        topSpeed: 45},
{brand: "Ford",         topSpeed: 6},
{brand: "Toyota",       topSpeed: 240},
{brand: "Chevrolet",    topSpeed: 120},
{brand: "Ferrari",      topSpeed: 1000}
];

// Sort Objects Numerically

arrayCarObjects.sort((a, b) => (a.topSpeed - b.topSpeed));

// Sort Objects Alphabetically

arrayCarObjects.sort((a, b) => (a.brand > b.brand) ? 1 : -1);

This steps are used in spring boot with self signed ssl certificate implementation

if SSL turns off then HTTPS call will be worked as expected.

https://localhost:8443/test/hello

These are the steps we have to follow,

1. Generate self signed ssl certificate

keytool -genkeypair -alias tomcat -keyalg RSA -keysize 2048 -storetype PKCS12 -keystore keystore.p12 -validity 3650

after key generation has done then copy that file in to the resource foder in your project

2. add key store properties in applicaiton.properties

server.port: 8443
server.ssl.key-store:classpath:keystore.p12
server.ssl.key-store-password: test123
server.ssl.keyStoreType: PKCS12
server.ssl.keyAlias: tomcat

3. change your postman ssl verification settings to turn OFF

now verify the url: https://localhost:8443/test/hello

Take a look at the section about filling in forms using webdriver in the selenium documentation and the javadoc for the Select class.

To select an option based on the label:

Select select = new Select(driver.findElement(By.xpath("//path_to_drop_down")));
select.deselectAll();
select.selectByVisibleText("Value1");

To get the first selected value:

WebElement option = select.getFirstSelectedOption()

I had the same problem with the laravel initiation. The solution was as follows.

1st - I checked the version of my PHP. That it was 5.6 would soon give problem with the laravel.

2nd - I changed the version of my PHP to PHP 7.1.1. ATTENTION, in my case I changed my environment variable that was getting Xampp's PHP version 5.6 I changed to 7.1.1 for laragon.

3rd - I went to the terminal / console and navigated to my folder where my project was and typed the following command: php artisan serves. And it worked! In my case it started at the port: 8000 see example below.

C: \ laragon \ www \ first> php artisan serves Laravel development server started: http://127.0.0.1:8000

I hope I helped someone who has been through the same problem as me.

Do you know the length of your prefix and suffix? In your case:

result=$(echo $string | cut -c5- | rev | cut -c3- | rev)

Or more general:

result=$(echo $string | cut -c$((${#prefix}+1))- | rev | cut -c$((${#suffix}+1))- | rev)

But the solution from Adrian Frühwirth is way cool! I didn't know about that!

Python is not Java, nor C/C++ -- you need to stop thinking that way to really utilize the power of Python.

Python does not have pass-by-value, nor pass-by-reference, but instead uses pass-by-name (or pass-by-object) -- in other words, nearly everything is bound to a name that you can then use (the two obvious exceptions being tuple- and list-indexing).

When you do spam = "green", you have bound the name spam to the string object "green"; if you then do eggs = spam you have not copied anything, you have not made reference pointers; you have simply bound another name, eggs, to the same object ("green" in this case). If you then bind spam to something else (spam = 3.14159) eggs will still be bound to "green".

When a for-loop executes, it takes the name you give it, and binds it in turn to each object in the iterable while running the loop; when you call a function, it takes the names in the function header and binds them to the arguments passed; reassigning a name is actually rebinding a name (it can take a while to absorb this -- it did for me, anyway).

With for-loops utilizing lists, there are two basic ways to assign back to the list:

for i, item in enumerate(some_list):
    some_list[i] = process(item)

or

new_list = []
for item in some_list:
    new_list.append(process(item))
some_list[:] = new_list

Notice the [:] on that last some_list -- it is causing a mutation of some_list's elements (setting the entire thing to new_list's elements) instead of rebinding the name some_list to new_list. Is this important? It depends! If you have other names besides some_list bound to the same list object, and you want them to see the updates, then you need to use the slicing method; if you don't, or if you do not want them to see the updates, then rebind -- some_list = new_list.

Add this to you PageLoad and it will solve your problem:

ScriptManager scriptManager = ScriptManager.GetCurrent(this.Page);
scriptManager.RegisterPostBackControl(this.lblbtndoc1);

Instead of removeClass and addClass, you can also do it like this:

$('.IsBestAnswer').toggleClass('IsBestAnswer bestanswer');
