From plt.imshow() official guide, we know that aspect controls the aspect ratio of the axes. Well in my words, the aspect is exactly the ratio of x unit and y unit. Most of the time we want to keep it as 1 since we do not want to distort out figures unintentionally. However, there is indeed cases that we need to specify aspect a value other than 1. The questioner provided a good example that x and y axis may have different physical units. Let's assume that x is in km and y in m. Hence for a 10x10 data, the extent should be [0,10km,0,10m] = [0, 10000m, 0, 10m]. In such case, if we continue to use the default aspect=1, the quality of the figure is really bad. We can hence specify aspect = 1000 to optimize our figure. The following codes illustrate this method.

%matplotlib inline
import numpy as np
import matplotlib.pyplot as plt
rng=np.random.RandomState(0)
data=rng.randn(10,10)
plt.imshow(data, origin = 'lower',  extent = [0, 10000, 0, 10], aspect = 1000)

Nevertheless, I think there is an alternative that can meet the questioner's demand. We can just set the extent as [0,10,0,10] and add additional xy axis labels to denote the units. Codes as follows.

plt.imshow(data, origin = 'lower',  extent = [0, 10, 0, 10])
plt.xlabel('km')
plt.ylabel('m')

To make a correct figure, we should always bear in mind that x_max-x_min = x_res * data.shape[1] and y_max - y_min = y_res * data.shape[0], where extent = [x_min, x_max, y_min, y_max]. By default, aspect = 1, meaning that the unit pixel is square. This default behavior also works fine for x_res and y_res that have different values. Extending the previous example, let's assume that x_res is 1.5 while y_res is 1. Hence extent should equal to [0,15,0,10]. Using the default aspect, we can have rectangular color pixels, whereas the unit pixel is still square!

plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10])
# Or we have similar x_max and y_max but different data.shape, leading to different color pixel res.
data=rng.randn(10,5)
plt.imshow(data, origin = 'lower',  extent = [0, 5, 0, 5])

The aspect of color pixel is x_res / y_res. setting its aspect to the aspect of unit pixel (i.e. aspect = x_res / y_res = ((x_max - x_min) / data.shape[1]) / ((y_max - y_min) / data.shape[0])) would always give square color pixel. We can change aspect = 1.5 so that x-axis unit is 1.5 times y-axis unit, leading to a square color pixel and square whole figure but rectangular pixel unit. Apparently, it is not normally accepted.

data=rng.randn(10,10)
plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10], aspect = 1.5)

The most undesired case is that set aspect an arbitrary value, like 1.2, which will lead to neither square unit pixels nor square color pixels.

plt.imshow(data, origin = 'lower',  extent = [0, 15, 0, 10], aspect = 1.2)

Long story short, it is always enough to set the correct extent and let the matplotlib do the remaining things for us (even though x_res!=y_res)! Change aspect only when it is a must.

There is no such thing as array constant in Go.

Quoting from the Go Language Specification: Constants:

There are boolean constants, rune constants, integer constants, floating-point constants, complex constants, and string constants. Rune, integer, floating-point, and complex constants are collectively called numeric constants.

A Constant expression (which is used to initialize a constant) may contain only constant operands and are evaluated at compile time.

The specification lists the different types of constants. Note that you can create and initialize constants with constant expressions of types having one of the allowed types as the underlying type. For example this is valid:

func main() {
    type Myint int
    const i1 Myint = 1
    const i2 = Myint(2)
    fmt.Printf("%T %v\n", i1, i1)
    fmt.Printf("%T %v\n", i2, i2)
}

Output (try it on the Go Playground):

main.Myint 1
main.Myint 2

If you need an array, it can only be a variable, but not a constant.

I recommend this great blog article about constants: Constants

This snippet is more accurate:

str.replace(/^(.+?)\/*?$/, "$1");

1. It not strips / strings, as it's a valid url.
2. It strips strings with multiple trailing slashes.

Converting a Java Keystore into PEM Format

The most precise answer of all must be that this is NOT possible.

A Java keystore is merely a storage facility for cryptographic keys and certificates while PEM is a file format for X.509 certificates only.

First create the file you want, with any editor like vi r gedit. And save with. Py extension.In that the first line should be

!/usr/bin/env python

First Record should be add

"_id" = 1    in your db

$database = "demo";
$collections ="democollaction";
echo getnextid($database,$collections);

function getnextid($database,$collections){

     $m = new MongoClient();
    $db = $m->selectDB($database);
    $cursor = $collection->find()->sort(array("_id" => -1))->limit(1);
    $array = iterator_to_array($cursor);

    foreach($array as $value){



        return $value["_id"] + 1;

    }
 }

current($array) can get you the first element of an array, according to the PHP manual.

Every array has an internal pointer to its "current" element, which is initialized to the first element inserted into the array.

So it works until you have re-positioned the array pointer, and otherwise you'll have to reset the array using reset()

I used this for a comment section:

.parent {_x000D_
    display: flex;_x000D_
    float: left;_x000D_

  <div class="child-left">Short</div>_x000D_
  <div class="child-right">Tall<br>Tall</div>_x000D_
</div>

You could float the child-right to the right, but in this case I've calculated the widths of each div precisely.

I'm still learning JavaScript, and the only way that I've found which works for me to compare two dates without the time is to use the setHours method of the Date object and set the hours, minutes, seconds and milliseconds to zero. Then compare the two dates.

For example,

date1 = new Date()
date2 = new Date(2011,8,20)

date2 will be set with hours, minutes, seconds and milliseconds to zero, but date1 will have them set to the time that date1 was created. To get rid of the hours, minutes, seconds and milliseconds on date1 do the following:

date1.setHours(0,0,0,0)

Now you can compare the two dates as DATES only without worrying about time elements.

Based on @mat-khor's answer, I took the syswin su.exe, saved it as manufacture-syswin-su.exe, and wrote this wrapper script. It handles redirection of the command's stdout and stderr, so it can be used in a pipe, etc. Also, the script exits with the status of the given command.

Limitations:

• The syswin-su options are currently hardcoded to use the current user. Prepending env USERNAME=... to the script invocation overrides it. If other options were needed, the script would have to distinguish between syswin-su and command arguments, e.g. splitting at the first --.
• If the UAC prompt is cancelled or declined, the script hangs.

.

#!/bin/bash
set -e

# join command $@ into a single string with quoting (required for syswin-su)
cmd=$( ( set -x; set -- "$@"; ) 2>&1 | perl -nle 'print $1 if /\bset -- (.*)/' )

tmpDir=$(mktemp -t -d -- "$(basename "$0")_$(date '+%Y%m%dT%H%M%S')_XXX")
mkfifo -- "$tmpDir/out"
mkfifo -- "$tmpDir/err"

cat >> "$tmpDir/script" <<-SCRIPT
    #!/bin/env bash
    $cmd > '$tmpDir/out' 2> '$tmpDir/err'
    echo \$? > '$tmpDir/status'
SCRIPT

chmod 700 -- "$tmpDir/script"

manufacture-syswin-su -s bash -u "$USERNAME" -m -c "cygstart --showminimized bash -c '$tmpDir/script'" > /dev/null &
cat -- "$tmpDir/err" >&2 &
cat -- "$tmpDir/out"
wait $!
exit $(<"$tmpDir/status")

Rotate by 90 degress around 0,0:

x' = -y
y' = x

Rotate by 90 degress around px,py:

x' = -(y - py) + px
y' = (x - px) + py

As the solution is hackish, I think using your own date/time widget with some JavaScript is more feasible.

MySQL Utilities by Oracle have a command called mysqldiskusage that displays the disk usage of every database: https://dev.mysql.com/doc/mysql-utilities/1.6/en/mysqldiskusage.html

I also had problems because my program interpreter was /lib/ld-linux.so.2 however it was on an embedded device, so I solved the problem by asking gcc to use ls-uClibc instead as follows:

-Wl,--dynamic-linker=/lib/ld-uClibc.so.0

This worked for me. Its tedious to set all the colour options for a series, especially if it's dynamic

plotOptions: {
  column: {
   colorByPoint: true
  }
}

The ToString method on the DateTime struct can take a format parameter:

var dateAsString = DateTime.Now.ToString("yyyy-MM-dd");
// dateAsString = "2011-02-17"

Documentation for standard and custom format strings is available on MSDN.

sentence="one;two;three"
a="${sentence};"
while [ -n "${a}" ]
do
    echo ${a%%;*}
    a=${a#*;}
done

Never mind, figured it out:

set wrap off
set linesize 3000 -- (or to a sufficiently large value to hold your results page)

Which I found by:

And looking for some option that seemed relevant.

The S parameter does not do anything on its own.

/S      Modifies the treatment of string after /C or /K (see below) 
/C      Carries out the command specified by string and then terminates  
/K      Carries out the command specified by string but remains  

Try something like this instead

Call Shell("cmd.exe /S /K" & "perl a.pl c:\temp", vbNormalFocus)

You may not even need to add "cmd.exe" to this command unless you want a command window to open up when this is run. Shell should execute the command on its own.

Shell("perl a.pl c:\temp")

-Edit-
To wait for the command to finish you will have to do something like @Nate Hekman shows in his answer here

Dim wsh As Object
Set wsh = VBA.CreateObject("WScript.Shell")
Dim waitOnReturn As Boolean: waitOnReturn = True
Dim windowStyle As Integer: windowStyle = 1

wsh.Run "cmd.exe /S /C perl a.pl c:\temp", windowStyle, waitOnReturn

toFixed() method formats a number using fixed-point notation. Read MDN Web Docs for full reference.

console.log(fval.toFixed(2)); // prints 4.00

You cannot use PuTTY to download the files, but you can use PSCP from the PuTTY developers to get the files or dump any directory that you want.

Is there something that prevents you from merging all revisions on trunk since the last merge?

svn merge -rLastRevisionMergedFromTrunkToBranch:HEAD url/of/trunk path/to/branch/wc

should work just fine. At least if you want to merge all changes on trunk to your branch.

Try this:

Display display   = getWindowManager().getDefaultDisplay();
Point displaySize = new Point();
display.getSize(displaySize);
int width  = displaySize.x;
int height = displaySize.y;

First off, you should use dataUsingEncoding: instead of going through UTF8String. You only use UTF8String when you need a C string in that encoding.

Then, for UTF-16, just pass NSUnicodeStringEncoding instead of NSUTF8StringEncoding in your dataUsingEncoding: message.

Try This:

SELECT systimestamp INTO time_db FROM dual ;

DBMS_OUTPUT.PUT_LINE('time before procedure ' || time_db);

Have you tried using the [FromUri] attribute when sending parameters over the query string.

Here is an example:

[HttpGet]
[Route("api/department/getndeptsfromid")]
public List<Department> GetNDepartmentsFromID([FromUri]int FirstId, [FromUri] int CountToFetch)
{
    return HHSService.GetNDepartmentsFromID(FirstId, CountToFetch);
}

Include this package at the top also, using System.Web.Http;

In Controller

return redirect()->route('company')->with('update', 'Content has been updated successfully!');

In view

@if (session('update'))
  <div class="alert alert-success alert-dismissable custom-success-box" style="margin: 15px;">
     <a href="#" class="close" data-dismiss="alert" aria-label="close">&times;</a>
     <strong> {{ session('update') }} </strong>
  </div>
@endif

This seems to provide the info on Windows:

1.) Open a windows command prompt.

2.) Key in: java -XshowSettings:all and hit ENTER.

3.) A lot of information will be displayed on the command window. Scroll up until you find the string: sun.arch.data.model.

4.) If it says sun.arch.data.model = 32, your VM is 32 bit. If it says sun.arch.data.model = 64, your VM is 64 bit.

set the dll path in the config file

<add key="dllPath" value="C:\Users\UserName\YourApp\myLibFolder\myDLL.dll" />

before calling the dll in you app, do the following

string dllPath= ConfigurationManager.AppSettings["dllPath"];    
   string appDirectory = Path.GetDirectoryName(dllPath);
   Directory.SetCurrentDirectory(appDirectory);

then call the dll and you can use like below

 [DllImport("myDLL.dll", CallingConvention = CallingConvention.Cdecl)]
public static extern int DLLFunction(int Number1, int Number2);

Go to command windows (cmd) then type:

"c:\Progam Files(x86)\GnuWin32\bin\awk"

The term business logic is in my opinion not a precise definition. Evans talks in his book, Domain Driven Design, about two types of business logic:

• Domain logic.
• Application logic.

This separation is in my opinion a lot clearer. And with the realization that there are different types of business rules also comes the realization that they don't all necessarily go the same place.

Domain logic is logic that corresponds to the actual domain. So if you are creating an accounting application, then domain rules would be rules regarding accounts, postings, taxation, etc. In an agile software planning tool, the rules would be stuff like calculating release dates based on velocity and story points in the backlog, etc.

For both these types of application, CSV import/export could be relevant, but the rules of CSV import/export has nothing to do with the actual domain. This kind of logic is application logic.

Domain logic most certainly goes into the model layer. The model would also correspond to the domain layer in DDD.

Application logic however does not necessarily have to be placed in the model layer. That could be placed in the controllers directly, or you could create a separate application layer hosting those rules. What is most logical in this case would depend on the actual application.

One-liner alternative to the built-in zfill.

This function takes x and converts it to a string, and adds zeros in the beginning only and only if the length is too short:

def zfill_alternative(x,len=4): return ( (('0'*len)+str(x))[-l:] if len(str(x))<len else str(x) )

To sum it up - build-in: zfill is good enough, but if someone is curious on how to implement this by hand, here is one more example.

All the stuff about .on() and .one() is great, and jquery is great.

But sometimes, you want it to be a little more obvious that the user isn't allowed to click, and in those cases you could do something like this:

function funName(){
    $("#orderButton").prop("disabled", true);
    //  do a bunch of stuff
    // and now that you're all done
    setTimeout(function(){
        $("#orderButton").prop("disabled",false);
        $("#orderButton").blur();
    }, 3000);
}

and your button would look like:

<button onclick='funName()'>Click here</button>

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world
=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

Even I had this issue while running python -m grpc_tools.protoc --version Had to set the PYTHONPATH till site-packages and shutdown all the command prompt windows and it worked. Hope it helps for gRPC users.

char buffer[64];
int ret = snprintf(buffer, sizeof buffer, "%f", myFloat);

if (ret < 0) {
    return EXIT_FAILURE;
}
if (ret >= sizeof buffer) {
    /* Result was truncated - resize the buffer and retry.
}

That will store the string representation of myFloat in myCharPointer. Make sure that the string is large enough to hold it, though.

snprintf is a better option than sprintf as it guarantees it will never write past the size of the buffer you supply in argument 2.

How does spring know which polymorphic type to use.

As long as there is only a single implementation of the interface and that implementation is annotated with @Component with Spring's component scan enabled, Spring framework can find out the (interface, implementation) pair. If component scan is not enabled, then you have to define the bean explicitly in your application-config.xml (or equivalent spring configuration file).

Do I need @Qualifier or @Resource?

Once you have more than one implementation, then you need to qualify each of them and during auto-wiring, you would need to use the @Qualifier annotation to inject the right implementation, along with @Autowired annotation. If you are using @Resource (J2EE semantics), then you should specify the bean name using the name attribute of this annotation.

Why do we autowire the interface and not the implemented class?

Firstly, it is always a good practice to code to interfaces in general. Secondly, in case of spring, you can inject any implementation at runtime. A typical use case is to inject mock implementation during testing stage.

interface IA
{
  public void someFunction();
}


class B implements IA
{
  public void someFunction()
  {
    //busy code block
  }
  public void someBfunc()
  {
     //doing b things
  }
}


class C implements IA
{
  public void someFunction()
  {
    //busy code block
  }
  public void someCfunc()
  {
     //doing C things
  }
}

class MyRunner
{
     @Autowire
     @Qualifier("b") 
     IA worker;

     ....
     worker.someFunction();
}

Your bean configuration should look like this:

<bean id="b" class="B" />
<bean id="c" class="C" />
<bean id="runner" class="MyRunner" />

Alternatively, if you enabled component scan on the package where these are present, then you should qualify each class with @Component as follows:

interface IA
{
  public void someFunction();
}

@Component(value="b")
class B implements IA
{
  public void someFunction()
  {
    //busy code block
  }
  public void someBfunc()
  {
     //doing b things
  }
}


@Component(value="c")
class C implements IA
{
  public void someFunction()
  {
    //busy code block
  }
  public void someCfunc()
  {
     //doing C things
  }
}

@Component    
class MyRunner
{
     @Autowire
     @Qualifier("b") 
     IA worker;

     ....
     worker.someFunction();
}

Then worker in MyRunner will be injected with an instance of type B.

To do this you need a JDBC Connection and/or driver that supports logging the sql at a low level.

Take a look at log4jdbc

If you use pandas, you can append your dataframes to an existing CSV file this way:

df.to_csv('log.csv', mode='a', index=False, header=False)

With mode='a' we ensure that we append, rather than overwrite, and with header=False we ensure that we append only the values of df rows, rather than header + values.

UPDATE 2017

Better documentation is now available and you can use both JSON and JavaScript based configurations: angular-cli documentation proxy

sample https proxy configuration

{
  "/angular": {
     "target":  {
       "host": "github.com",
       "protocol": "https:",
       "port": 443
     },
     "secure": false,
     "changeOrigin": true,
     "logLevel": "info"
  }
}

To my knowledge with Angular 2.0 release setting up proxies using .ember-cli file is not recommended. official way is like below

1. edit "start" of your package.json to look below

   "start": "ng serve --proxy-config proxy.conf.json",

2. create a new file called proxy.conf.json in the root of the project and inside of that define your proxies like below

   {
     "/api": {
       "target": "http://api.yourdomai.com",
       "secure": false
     }
   }
   

3. Important thing is that you use npm start instead of ng serve

There is an overload of Url.Action that takes your desired protocol (e.g. http, https) as an argument - if you specify this, you get a fully qualified URL.

Here's an example that uses the protocol of the current request in an action method:

var fullUrl = this.Url.Action("Edit", "Posts", new { id = 5 }, this.Request.Url.Scheme);

HtmlHelper (@Html) also has an overload of the ActionLink method that you can use in razor to create an anchor element, but it also requires the hostName and fragment parameters. So I'd just opt to use @Url.Action again:

<span>
  Copy
  <a href='@Url.Action("About", "Home", null, Request.Url.Scheme)'>this link</a> 
  and post it anywhere on the internet!
</span>

create backup

This code is easier to use:

 View rowView = listView.getChildAt(viewIndex);//The item number in the List View
    if(rowView != null)
        {
           // Your code here
        }

Object coalesce(Object... objects)
{
    for(Object o : object)
        if(o != null)
            return o;
    return null;
}

Focus doesn't work on divs by default. But, according to this, you can make it work:

The focus event is sent to an element when it gains focus. This event is implicitly applicable to a limited set of elements, such as form elements (<input>, <select>, etc.) and links (<a href>). In recent browser versions, the event can be extended to include all element types by explicitly setting the element's tabindex property. An element can gain focus via keyboard commands, such as the Tab key, or by mouse clicks on the element.

@Emracool... I'd suggest you an alternative. Since you seem to be trying to load a *.txt file. Better to use FileInputStream() rather then this annoying getClass().getClassLoader().getResourceAsStream() or getClass().getResourceAsStream(). At least your code will execute properly.

For what it's worth, if you're dealing with code which relies on assert to function properly, then adding the following code will ensure that asserts are enabled:

try:
    assert False
    raise Exception('Python assertions are not working. This tool relies on Python assertions to do its job. Possible causes are running with the "-O" flag or running a precompiled (".pyo" or ".pyc") module.')
except AssertionError:
    pass

I was getting this error while trying to show DatePicker from Fragment.

I changed

val datePickerDialog = DatePickerDialog(activity!!.applicationContext, ...)

to

val datePickerDialog = DatePickerDialog(requireContext(), ...)

and it worked just fine.

Yes, SQL Server 2012 supports multiple inserts - that feature was introduced in SQL Server 2008.

That makes me wonder if you have Management Studio 2012, but you're really connected to a SQL Server 2005 instance ...

What version of the SQL Server engine do you get from SELECT @@VERSION ??

$address = str_replace(" ", "+", $address);

Use the above code before the file_get_content. means, use the following code

$address = str_replace(" ", "+", $address);

$json = file_get_contents("http://maps.google.com/maps/api/geocode/json?address=$address&sensor=false&region=$region");
$json = json_decode($json);

$lat = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lat'};
$long = $json->{'results'}[0]->{'geometry'}->{'location'}->{'lng'};

and it will work surely. As address does not support spaces it supports only + sign in place of space.

Restart IIS- could be a process attached to the debugger

If nothing of the above helps, check if there is margin-top set on some of the (some levels below) nested DOM element(s).

It will be not recognizable when you inspect body element itself in the debugger. It will only be visible when you unfold several elements nested down in body element in Chrome Dev Tools elements debugger and check if there is one of them with margin-top set.

The below is the upper part of a site screen shot and the corresponding Chrome Dev Tools view when you inspect body tag.

No sign of top margin here and you have resetted all the browser-scpecific CSS properties as per answers above but that unwanted white space is still here.

The following is a view when you inspect the right nested element. It is clearly seen the orange'ish top-margin is set on it. This is the one that causes the white space on top of body element.

On that found element replace margin-top with padding-top if you need space above it and yet not to leak it above the body tag.

Hope that helps :)

on duplicate key update, or insert ignore can be viable solutions with MySQL.

No, you can't change scrollbars placement without any additional issues.

You can change text-direction to right-to-left ( rtl ), but it also change text position inside block.

This code can helps you, but I not sure it works in all browsers and OS.

<element style="direction: rtl; text-align: left;" />

In a case statement, a , is the equivalent of || in an if statement.

Some other things you can do with a Ruby case statement

Another perspective for doing it on Linux... here is how to do it so that the resulting single file contains the decrypted private key so that something like HAProxy can use it without prompting you for passphrase.

openssl pkcs12 -in file.pfx -out file.pem -nodes

Then you can configure HAProxy to use the file.pem file.

This is an EDIT from previous version where I had these multiple steps until I realized the -nodes option just simply bypasses the private key encryption. But I'm leaving it here as it may just help with teaching.

openssl pkcs12 -in file.pfx -out file.nokey.pem -nokeys
openssl pkcs12 -in file.pfx -out file.withkey.pem
openssl rsa -in file.withkey.pem -out file.key
cat file.nokey.pem file.key > file.combo.pem

1. The 1st step prompts you for the password to open the PFX.
2. The 2nd step prompts you for that plus also to make up a passphrase for the key.
3. The 3rd step prompts you to enter the passphrase you just made up to store decrypted.
4. The 4th puts it all together into 1 file.

Then you can configure HAProxy to use the file.combo.pem file.

The reason why you need 2 separate steps where you indicate a file with the key and another without the key, is because if you have a file which has both the encrypted and decrypted key, something like HAProxy still prompts you to type in the passphrase when it uses it.

Try this:

$old_date = date('y-m-d-h-i-s');
$new_date = date('Y-m-d H:i:s', strtotime($old_date));

If you are using Mac OS and have updated XCode you probably need to open XCode and accept the terms to avoid this error.

Although GitHub removed the private messaging feature, there's still an alternative.

GitHub host git repositories. If the user you're willing to communicate with has ever committed some code, there are good chances you may reach your goal. Indeed, within each commit is stored some information about the author of the change or the one who accepted it.

Provided you're really dying to exchange with user user_test

• Display the public activity page of the user: https://github.com/user_test?tab=activity
• Search for an event stating "user_test pushed to [branch] at [repository]". There are usually good chances, they may have pushed one of his own commits. Ensure this is the case by clicking on the "View comparison..." link and make sure the user is listed as one of the committers.
• Clone on your local machine the repository they pushed to: git clone https://github.com/..../repository.git
• Checkout the branch they pushed to: git checkout [branch]
• Display the latest commits: git log -50

As a committer/author, an email should be displayed along with the commit data.

Note: Every warning related to unsolicited email should apply there. Do not spam.

Hey so the accepted answer works, except if you need to debug the initial launch of the app. However I think that answer is more of a work around, and not an actual solution. From my understanding this message occurs when you have some weirdness in your provisioning profile / cert setup so make extra sure everything is in tip-top shape in that dept. before ramming your head against the wall repeatedly.

What worked for me was as follows from the apple docs:

Provisioning Profiles Known Issue If you have upgraded to the GM seed from other betas you may see your apps crashing due to provisioning profile issues.

Workaround:

1. Connect the device via USB to your Mac

2. Launch Xcode Choose Window ->Devices

3. Right click on the device in left column, choose "Show Provisioning Profiles"

4. Click on the provisioning profile in question

5. Press the "-" button Continue to removing all affected profiles.

6. Re-install the app

Make sure you right click on the image of the device not the name of the device or you won't see the provisioning profiles option. I restored my new phone from an old backup and there was a lot of cruft hanging around, i also had 2 different dev. certs active (not sure why) but i deleted one, made a new profile got rid of all the profiles on device and it worked.

Hope this helps someone else.

This message displays when Internet Explorer reaches the maximum number of synchronous instructions for a piece of JavaScript. The default maximum is 5,000,000 instructions, you can increase this number on a single machine by editing the registry.

Internet Explorer now tracks the total number of executed script statements and resets the value each time that a new script execution is started, such as from a timeout or from an event handler, for the current page with the script engine. Internet Explorer displays a "long-running script" dialog box when that value is over a threshold amount.

The only way to solve the problem for all users that might be viewing your page is to break up the number of iterations your loop performs using timers, or refactor your code so that it doesn't need to process as many instructions.

Breaking up a loop with timers is relatively straightforward:

var i=0;
(function () {
    for (; i < 6000000; i++) {
        /*
            Normal processing here
        */

        // Every 100,000 iterations, take a break
        if ( i > 0 && i % 100000 == 0) {
            // Manually increment `i` because we break
            i++;
            // Set a timer for the next iteration 
            window.setTimeout(arguments.callee);
            break;
        }
    }
})();

For an easy fix, you could

echo 1 > /proc/sys/vm/overcommit_memory

if your're sure that your system has enough memory. See Linux over commit heuristic.

you can use ? at the end to skip one "\"

regex("\\\\?")

$newarr=arsort($arr);
$max_key=array_shift(array_keys($new_arr));

I present you the right solution

For Xcode 11+

Step 1: Add a ScrollView and resize it

Step 2: Add Constraints for a ScrollView

Step 3: Add a StackView into ScrollView, and resize it.

Step 4: Add Constraints for a StackView (Stask View -> Content Layout Guide -> "Leading, Top, Trailing, Bottom")

Step 4.1: Correct Constraints -> Constant (... -> Constant = 0)

Step 5: Add Constraints for a StackView (Stask View -> Frame Layout Guide -> "Equal Widths")

Step 6 Example: Add two UIView(s) with HeightConstraints and RUN

I stumbled upon this question due to the same problem but none of the answers helps if you need to behave exactly like setInterval() but with the only difference that the function is called immediately at the beginning.

Here is my solution to this problem:

function setIntervalImmediately(func, interval) {
  func();
  return setInterval(func, interval);
}

The advantage of this solution:

• existing code using setInterval can easily be adapted by substitution
• works in strict mode
• it works with existing named functions and closures
• you can still use the return value and pass it to clearInterval() later

Example:

// create 1 second interval with immediate execution
var myInterval = setIntervalImmediately( _ => {
        console.log('hello');
    }, 1000);

// clear interval after 4.5 seconds
setTimeout( _ => {
        clearInterval(myInterval);
    }, 4500);

To be cheeky, if you really need to use setInterval then you could also replace the original setInterval. Hence, no change of code required when adding this before your existing code:

var setIntervalOrig = setInterval;

setInterval = function(func, interval) {
    func();
    return setIntervalOrig(func, interval);
}

Still, all advantages as listed above apply here but no substitution is necessary.

I have encountered this problem and finally solved it today, so I write down what I have learned and I hope it is helpful for someone who is new to Android's ViewPager and update as I do. I'm using FragmentStatePagerAdapter in API level 17 and currently have just 2 fragments. I think there must be something not correct, please correct me, thanks.

1. Serialized data has to be loaded into memory. This can be done using a CursorLoader/AsyncTask/Thread. Whether it's automatically loaded depends on your code. If you are using a CursorLoader, it's auto-loaded since there is a registered data observer.

2. After you call viewpager.setAdapter(pageradapter), the adapter's getCount() is constantly called to build fragments. So if data is being loaded, getCount() can return 0, thus you don't need to create dummy fragments for no data shown.

3. After the data is loaded, the adapter will not build fragments automatically since getCount() is still 0, so we can set the actually loaded data number to be returned by getCount(), then call the adapter's notifyDataSetChanged(). ViewPager begin to create fragments (just the first 2 fragments) by data in memory. It's done before notifyDataSetChanged() is returned. Then the ViewPager has the right fragments you need.

4. If the data in the database and memory are both updated (write through), or just data in memory is updated (write back), or only data in the database is updated. In the last two cases if data is not automatically loaded from the database to memory (as mentioned above). The ViewPager and pager adapter just deal with data in memory.

5. So when data in memory is updated, we just need to call the adapter's notifyDataSetChanged(). Since the fragment is already created, the adapter's onItemPosition() will be called before notifyDataSetChanged() returns. Nothing needs to be done in getItemPosition(). Then the data is updated.

tl;dr 2016 Use RxJava and a PublishSubject to expose an Observable for the clicks.

public class ReactiveAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {
    String[] mDataset = { "Data", "In", "Adapter" };

    private final PublishSubject<String> onClickSubject = PublishSubject.create();

    @Override 
    public void onBindViewHolder(final ViewHolder holder, int position) {
        final String element = mDataset[position];

        holder.itemView.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
               onClickSubject.onNext(element);
            }
        });
    }

    public Observable<String> getPositionClicks(){
        return onClickSubject.asObservable();
    }
}

Original Post:

Since the introduction of ListView, onItemClickListener has been problematic. The moment you have a click listener for any of the internal elements the callback would not be triggered but it wasn't notified or well documented (if at all) so there was a lot of confusion and SO questions about it.

Given that RecyclerView takes it a step further and doesn't have a concept of a row/column, but rather an arbitrarily laid out amount of children, they have delegated the onClick to each one of them, or to programmer implementation.

Think of Recyclerview not as a ListView 1:1 replacement but rather as a more flexible component for complex use cases. And as you say, your solution is what google expected of you. Now you have an adapter who can delegate onClick to an interface passed on the constructor, which is the correct pattern for both ListView and Recyclerview.

public static class ViewHolder extends RecyclerView.ViewHolder implements OnClickListener {

    public TextView txtViewTitle;
    public ImageView imgViewIcon;
    public IMyViewHolderClicks mListener;

    public ViewHolder(View itemLayoutView, IMyViewHolderClicks listener) {
        super(itemLayoutView);
        mListener = listener;
        txtViewTitle = (TextView) itemLayoutView.findViewById(R.id.item_title);
        imgViewIcon = (ImageView) itemLayoutView.findViewById(R.id.item_icon);
        imgViewIcon.setOnClickListener(this);
        itemLayoutView.setOnClickListener(this);
    }

    @Override
    public void onClick(View v) {
        if (v instanceof ImageView){
           mListener.onTomato((ImageView)v);
        } else {
           mListener.onPotato(v);
        }
    }

    public static interface IMyViewHolderClicks {
        public void onPotato(View caller);
        public void onTomato(ImageView callerImage);
    }

}

and then on your adapter

public class MyAdapter extends RecyclerView.Adapter<MyAdapter.ViewHolder> {

   String[] mDataset = { "Data" };

   @Override
   public MyAdapter.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
       View v = LayoutInflater.from(parent.getContext()).inflate(R.layout.my_layout, parent, false);

       MyAdapter.ViewHolder vh = new ViewHolder(v, new MyAdapter.ViewHolder.IMyViewHolderClicks() { 
           public void onPotato(View caller) { Log.d("VEGETABLES", "Poh-tah-tos"); };
           public void onTomato(ImageView callerImage) { Log.d("VEGETABLES", "To-m8-tohs"); }
        });
        return vh;
    }

    // Replace the contents of a view (invoked by the layout manager) 
    @Override 
    public void onBindViewHolder(ViewHolder holder, int position) {
        // Get element from your dataset at this position 
        // Replace the contents of the view with that element 
        // Clear the ones that won't be used
        holder.txtViewTitle.setText(mDataset[position]);
    } 

    // Return the size of your dataset (invoked by the layout manager) 
    @Override 
    public int getItemCount() { 
        return mDataset.length;
    } 
  ...

Now look into that last piece of code: onCreateViewHolder(ViewGroup parent, int viewType) the signature already suggest different view types. For each one of them you'll require a different viewholder too, and subsequently each one of them can have a different set of clicks. Or you can just create a generic viewholder that takes any view and one onClickListener and applies accordingly. Or delegate up one level to the orchestrator so several fragments/activities have the same list with different click behaviour. Again, all flexibility is on your side.

It is a really needed component and fairly close to what our internal implementations and improvements to ListView were until now. It's good that Google finally acknowledges it.

I had this problem too and for me, the problem was that I moved to a new server and the database I was trying to connect to with my PHP code changed from "my_Database" to "my_database".

It depends on what you mean:

• As mentioned String.hashCode() gives you a 32 bit hash code.

• If you want (say) a 64-bit hashcode you can easily implement it yourself.

• If you want a cryptographic hash of a String, the Java crypto libraries include implementations of MD5, SHA-1 and so on. You'll typically need to turn the String into a byte array, and then feed that to the hash generator / digest generator. For example, see @Bryan Kemp's answer.

• If you want a guaranteed unique hash code, you are out of luck. Hashes and hash codes are non-unique.

A Java String of length N has 65536 ^ N possible states, and requires an integer with 16 * N bits to represent all possible values. If you write a hash function that produces integer with a smaller range (e.g. less than 16 * N bits), you will eventually find cases where more than one String hashes to the same integer; i.e. the hash codes cannot be unique. This is called the Pigeonhole Principle, and there is a straight forward mathematical proof. (You can't fight math and win!)

But if "probably unique" with a very small chance of non-uniqueness is acceptable, then crypto hashes are a good answer. The math will tell you how big (i.e. how many bits) the hash has to be to achieve a given (low enough) probability of non-uniqueness.

Using base-n mini lib, you can do the following:

some_data_t in[] { ... };
constexpr int len = sizeof(in)/sizeof(in[0]);

std::string encoded;
bn::encode_b64(in, in + len, std::back_inserter(encoded));

some_data_t out[len];
bn::decode_b64(encoded.begin(), encoded.end(), out);

The API is generic, iterator-based.

Disclosure: I'm the author.

First of all - prerequisite for downcast is that object you are casting is of the type you are casting to. Casting with dynamic_cast will check this condition in runtime (provided that casted object has some virtual functions) and throw bad_cast or return NULL pointer on failure. Compile-time casts will not check anything and will just lead tu undefined behaviour if this prerequisite does not hold.
Now analyzing your code:

DerivedType m_derivedType = m_baseType;

Here there is no casting. You are creating a new object of type DerivedType and try to initialize it with value of m_baseType variable.

Next line is not much better:

DerivedType m_derivedType = (DerivedType)m_baseType;

Here you are creating a temporary of DerivedType type initialized with m_baseType value.

The last line

DerivedType * m_derivedType = (DerivedType*) & m_baseType;

should compile provided that BaseType is a direct or indirect public base class of DerivedType. It has two flaws anyway:

1. You use deprecated C-style cast. The proper way for such casts is
   static_cast<DerivedType *>(&m_baseType)
2. The actual type of casted object is not of DerivedType (as it was defined as BaseType m_baseType; so any use of m_derivedType pointer will result in undefined behaviour.

I recently wrote a gem to simplify this process and to neaten up your views, etc etc.

Check it out at: http://github.com/platform45/easy_dates

ltrim:

$str = ltrim($str, '0');

Please use an inner query inside of the in-clause:

select col1, col2, col3... from table1
 where id in (select id from table2 where conditions...)

You could just re-direct specific numbers in your contacts to your voice-mail. That's already supported.

Otherwise I guess the documentation for 'Contacts' would be a good place to start looking.

As you stated in the comments, some of the values appeared to be floats, not strings. You will need to change it to strings before passing it to re.sub. The simplest way is to change location to str(location) when using re.sub. It wouldn't hurt to do it anyways even if it's already a str.

letters_only = re.sub("[^a-zA-Z]",  # Search for all non-letters
                          " ",          # Replace all non-letters with spaces
                          str(location))

Technically the information is available to you, but as others have asked, how would you make use of it in a sensible way?

>>> x = 52
>>> globals()
{'__builtins__': <module '__builtin__' (built-in)>, '__name__': '__main__', 
'x': 52, '__doc__': None, '__package__': None}

This shows that the variable name is present as a string in the globals() dictionary.

>>> globals().keys()[2]
'x'

In this case it happens to be the third key, but there's no reliable way to know where a given variable name will end up

>>> for k in globals().keys():
...   if not k.startswith("_"):
...     print k
...
x
>>>

You could filter out system variables like this, but you're still going to get all of your own items. Just running that code above created another variable "k" that changed the position of "x" in the dict.

But maybe this is a useful start for you. If you tell us what you want this capability for, more helpful information could possibly be given.

Python is not the best tool for this task. I tried several approaches in Python but none of them work 100% (e.g. 10% converts to 0.1, or column types are messed up, etc). The right tool here is PowerShell, because it is an MS product (as is Excel) and has the best integration.

Simply download this PowerShell script, edit line 47 to enter the path for the folder containing the Excel files and run the script using PowerShell.

You can do this:

df.rename(columns={ df.columns[1]: "whatever" })

Just as others stated you need to remove the ';' from:
;extension=php_mysql.dll and
;extension=php_mysqli.dll

in your php.ini to enable mysql and mysqli extensions. But MOST IMPORTANT of all, you should set the extension_dir in your php.ini to point to your extensions directory. The default most of the time is "ext". You should change it to the absolute path to the extensions folder. i.e. if you have your xampp installed on drive C, then C:/xampp/php/ext is the absolute path to the ext folder, and It should work like a charm!

As everyone has mentioned http.server module is equivalent to python -m SimpleHTTPServer.
But as a warning from https://docs.python.org/3/library/http.server.html#module-http.server

Warning: http.server is not recommended for production. It only implements basic security checks.

Usage

http.server can also be invoked directly using the -m switch of the interpreter.

python -m http.server

The above command will run a server by default on port number 8000. You can also give the port number explicitly while running the server

python -m http.server 9000

The above command will run an HTTP server on port 9000 instead of 8000.

By default, server binds itself to all interfaces. The option -b/--bind specifies a specific address to which it should bind. Both IPv4 and IPv6 addresses are supported. For example, the following command causes the server to bind to localhost only:

python -m http.server 8000 --bind 127.0.0.1

or

python -m http.server 8000 -b 127.0.0.1

Python 3.8 version also supports IPv6 in the bind argument.

Directory Binding

By default, server uses the current directory. The option -d/--directory specifies a directory to which it should serve the files. For example, the following command uses a specific directory:

python -m http.server --directory /tmp/

Directory binding is introduced in python 3.7

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

There isn't anything built-in, but you can easily create your own extension method to do it:

public static void ForEach<T>(this IEnumerable<T> source, Action<T> action)
{
    if (source == null) throw new ArgumentNullException("source");
    if (action == null) throw new ArgumentNullException("action");

    foreach (T item in source)
    {
        action(item);
    }
}

This is an old question yet I find that I also need a solution for this from time to time. The previous answers are all good and works well, I just personally prefer using CTE, for example:

DECLARE @T TABLE (ARIDNR INT, LIEFNR varchar(5)) --table variable for loading sample data
INSERT INTO @T (ARIDNR, LIEFNR) VALUES (1,'A'),(2,'A'),(3,'A'),(1,'B'),(2,'B'); --add your sample data to it
WITH duplicates AS --the CTE portion to find the duplicates
(
    SELECT ARIDNR FROM @T GROUP BY ARIDNR HAVING COUNT(*) > 1
)
SELECT t.* FROM @T t --shows results from main table
INNER JOIN duplicates d on t.ARIDNR = d.ARIDNR --where the main table can be joined to the duplicates CTE

Yields the following results:

1|A
1|B
2|B
2|A

Maybe this post is old, but I came across it and used the "wrong" usage. The best way to find a keyword is using .contains, example:

if ( d.contains("hello")) {
            System.out.println("I found the keyword");
}

2- Select the General pane, and scroll to the App Icons section.

3- Specify an image in the App Icon table by clicking the folder icon on the right side of the image row and selecting the image file in the dialog that appears.

4-Migrate the images in the App Icon table to an asset catalog by clicking the Use Asset Catalog button, selecting an asset catalog from the popup menu, and clicking the Migrate button.

Alternatively, you can create an empty app icon set by choosing Editor > New App Icon, and add images to the set by dragging them from the Finder or by choosing Editor > Import.

As @Travis Solution works but in some cases

var millisecondsSince1970:Int WILL CAUSE CRASH APPLICATION ,

with error

Double value cannot be converted to Int because the result would be greater than Int.max if it occurs Please update your answer with Int64

Here is Updated Answer

extension Date {
 var millisecondsSince1970:Int64 {
        return Int64((self.timeIntervalSince1970 * 1000.0).rounded()) 
        //RESOLVED CRASH HERE
    }

    init(milliseconds:Int) {
        self = Date(timeIntervalSince1970: TimeInterval(milliseconds / 1000))
    }
}

About Int definitions.

On 32-bit platforms, Int is the same size as Int32, and on 64-bit platforms, Int is the same size as Int64.

Generally, I encounter this problem in iPhone 5, which runs in 32-bit env. New devices run 64-bit env now. Their Int will be Int64.

Hope it is helpful to someone who also has same problem

I tried out solution suggested by Russ Bateman Here in the post

http://localhost:8080/Myapp to http://localhost:8080/somepath/Myapp

But Didnt worked for me as I needed to have a *.war file that can hold the config and not the individual instance of server on my localmachine.

Reference

In order to do that I need jboss-web.xml placed in WEB-INF

Many of the Python 2 implementations here will fail if there is no controlling terminal when you call this script. You can check sys.stdout.isatty() to determine if this is in fact a terminal, but that will exclude a bunch of cases, so I believe the most pythonic way to figure out the terminal size is to use the builtin curses package.

import curses
w = curses.initscr()
height, width = w.getmaxyx()

Update: This process is so common, that the git team made it much simpler with a new tool, git subtree. See here: Detach (move) subdirectory into separate Git repository

You want to clone your repository and then use git filter-branch to mark everything but the subdirectory you want in your new repo to be garbage-collected.

1. To clone your local repository:

   git clone /XYZ /ABC
   

   (Note: the repository will be cloned using hard-links, but that is not a problem since the hard-linked files will not be modified in themselves - new ones will be created.)

2. Now, let us preserve the interesting branches which we want to rewrite as well, and then remove the origin to avoid pushing there and to make sure that old commits will not be referenced by the origin:

   cd /ABC
   for i in branch1 br2 br3; do git branch -t $i origin/$i; done
   git remote rm origin
   

   or for all remote branches:

   cd /ABC
   for i in $(git branch -r | sed "s/.*origin\///"); do git branch -t $i origin/$i; done
   git remote rm origin
   

3. Now you might want to also remove tags which have no relation with the subproject; you can also do that later, but you might need to prune your repo again. I did not do so and got a WARNING: Ref 'refs/tags/v0.1' is unchanged for all tags (since they were all unrelated to the subproject); additionally, after removing such tags more space will be reclaimed. Apparently git filter-branch should be able to rewrite other tags, but I could not verify this. If you want to remove all tags, use git tag -l | xargs git tag -d.

4. Then use filter-branch and reset to exclude the other files, so they can be pruned. Let's also add --tag-name-filter cat --prune-empty to remove empty commits and to rewrite tags (note that this will have to strip their signature):

   git filter-branch --tag-name-filter cat --prune-empty --subdirectory-filter ABC -- --all
   

   or alternatively, to only rewrite the HEAD branch and ignore tags and other branches:

   git filter-branch --tag-name-filter cat --prune-empty --subdirectory-filter ABC HEAD
   

5. Then delete the backup reflogs so the space can be truly reclaimed (although now the operation is destructive)

   git reset --hard
   git for-each-ref --format="%(refname)" refs/original/ | xargs -n 1 git update-ref -d
   git reflog expire --expire=now --all
   git gc --aggressive --prune=now
   

   and now you have a local git repository of the ABC sub-directory with all its history preserved.

Note: For most uses, git filter-branch should indeed have the added parameter -- --all. Yes that's really --space-- all. This needs to be the last parameters for the command. As Matli discovered, this keeps the project branches and tags included in the new repo.

Edit: various suggestions from comments below were incorporated to make sure, for instance, that the repository is actually shrunk (which was not always the case before).

You will simply need to do a type check for each of the basic numeric types.

Here's an extension method that should do the job:

public static bool IsNumber(this object value)
{
    return value is sbyte
            || value is byte
            || value is short
            || value is ushort
            || value is int
            || value is uint
            || value is long
            || value is ulong
            || value is float
            || value is double
            || value is decimal;
}

This should cover all numeric types.

Update

It seems you do actually want to parse the number from a string during deserialisation. In this case, it would probably just be best to use double.TryParse.

string value = "123.3";
double num;
if (!double.TryParse(value, out num))
    throw new InvalidOperationException("Value is not a number.");

Of course, this wouldn't handle very large integers/long decimals, but if that is the case you just need to add additional calls to long.TryParse / decimal.TryParse / whatever else.

To this error:

# git pull
sign_and_send_pubkey: signing failed: agent refused operation
[email protected]: Permission denied (publickey).    
fatal: Could not read from remote repository.

Please make sure you have the correct access rights and the repository exists.

Verify or add again the public key in Github account > profile > ssh.

I solved like this:

# chmod 400 ~/.ssh/id_rsa

# ls  ~/.ssh/id_rsa -ls  
4 -r--------. 1 reinaldo reinaldo 1679 Jul 26  2017 /home/reinaldo/.ssh/id_rsa

The very first thing you need to do is download extras and tools package from SDK manager and other necessary packages like platform-25 and so on.. , after that open AVD manager and select any emulator you wan't, after that go to "other images" tab and select ARM AEBI a7a System Image and select finish and you are all done hope this would help you.

I can confirm that this bug is still present in Ubuntu 19.04 (Disco Dingo). The workaround suggested by VonC worked perfectly, summarizing for my version:

• Click on Activities tab on top left corner
• On the search box that comes up, begin typing "startup applications"
• Click on the "Startup Applications" icon
• On the box that pops up, select the gnome key ring manager application (can't remember the exact name on the GUI but it is distinctive enough) and remove it.

Next, I tried ssh-add -D again, and after reboot ssh-add -l told me The agent has no identities. I confirmed that I still had the ssh-agent daemon running with ps aux | grep agent. So I added the key I most frequently used with GitHub (ssh-add ~/.ssh/id_ecdsa) and all was good!

Now I can do the normal operations with my most frequently used repository, and if I occasionally require access to the other repository which uses the RSA key, I just dedicate one terminal for it with export GIT_SSH_COMMAND="ssh -i /home/me/.ssh/id_rsa.pub". Solved! Credit goes to VonC for pointing out the bug and the solution.

In my case I was using MySql Server version: 8.0.22

I had to add

bind-address        = 0.0.0.0

and change this line to be

mysqlx-bind-address = 0.0.0.0

in file at /etc/mysql/mysql.conf.d

then restart MySQL by running

sudo service mysql restart

The web site likely uses cookies to store your session information. When you run

curl --user user:pass https://xyz.com/a  #works ok
curl https://xyz.com/b #doesn't work

curl is run twice, in two separate sessions. Thus when the second command runs, the cookies set by the 1st command are not available; it's just as if you logged in to page a in one browser session, and tried to access page b in a different one.

What you need to do is save the cookies created by the first command:

curl --user user:pass --cookie-jar ./somefile https://xyz.com/a

and then read them back in when running the second:

curl --cookie ./somefile https://xyz.com/b

Alternatively you can try downloading both files in the same command, which I think will use the same cookies.

Use the .clone() method on your List. It will return a shallow copy, meaning that it will contain pointers to the same objects, so you won't have to copy the list. Then just use Collections.

Ergo,

Collections.reverse(list.clone());

If you are using a List and don't have access to clone() you can use subList():

List<?> shallowCopy = list.subList(0, list.size());
Collections.reverse(shallowCopy);

Use is simple:

convert(date, Btch_Time)

Example below:

Table:

Efft_d       Loan_I  Loan_Purp_Type_C   Orig_LTV    Curr_LTV    Schd_LTV    Un_drwn_Bal_a      Btch_Time            Strm_I  Btch_Ins_I
2014-05-31  200312500   HL03             NULL         1.0000    1.0000         1.0000      2014-06-17 11:10:57.330  1005    24851e0a-53983699-14b4-69109

Select * from helios.dbo.CBA_SRD_Loan where Loan_I in ('200312500') and convert(date, Btch_Time) = '2014-06-17'

Method to read JSON file from Assets folder and return as a string object.

public static String getAssetJsonData(Context context) {
            String json = null;
            try {
                InputStream is = context.getAssets().open("myJson.json");
                int size = is.available();
                byte[] buffer = new byte[size];
                is.read(buffer);
                is.close();
                json = new String(buffer, "UTF-8");
            } catch (IOException ex) {
                ex.printStackTrace();
                return null;
            }

            Log.e("data", json);
            return json;

        }

Now for parsing data in your activity:-

String data = getAssetJsonData(getApplicationContext());
        Type type = new TypeToken<Your Data model>() {
        }.getType();
  <Your Data model> modelObject = new Gson().fromJson(data, type);

All of the answers didn't work for me, I checked the playlist URL and seen that playlist parameter changed to list! So it should be:

&loop=1&list=PLvNxGp1V1dOwpDBl7L3AJIlkKYdNDKUEs

So here is the full code I use make a clean, looping, autoplay video:

<iframe width="100%" height="425" src="https://www.youtube.com/embed/MavEpJETfgI?autoplay=1&showinfo=0&loop=1&list=PLvNxGp1V1dOwpDBl7L3AJIlkKYdNDKUEs&rel=0" frameborder="0" allowfullscreen></iframe>

Quoted from the javadoc;

This interface imposes a total ordering on the objects of each class that implements it. This ordering is referred to as the class's natural ordering, and the class's compareTo method is referred to as its natural comparison method.

Lists (and arrays) of objects that implement this interface can be sorted automatically by Collections.sort (and Arrays.sort). Objects that implement this interface can be used as keys in a sorted map or as elements in a sorted set, without the need to specify a comparator.

Edit: ..and made the important bit bold.

This fixed my problem:

ng generate component nameComponent --module app.module

Upcasting and Downcasting:

Upcasting: Casting from Derived-Class to Base Class Downcasting: Casting from Base Class to Derived Class

Let's understand the same as an example:

Consider two classes Shape as My parent class and Circle as a Derived class, defined as follows:

class Shape
{
    public int Width { get; set; }
    public int Height { get; set; }
}

class Circle : Shape
{
    public int Radius { get; set; }
    public bool FillColor { get; set; }
}

Upcasting:

Shape s = new Shape();

Circle c= s;

Both c and s are referencing to the same memory location, but both of them have different views i.e using "c" reference you can access all the properties of the base class and derived class as well but using "s" reference you can access properties of the only parent class.

A practical example of upcasting is Stream class which is baseclass of all types of stream reader of .net framework:

StreamReader reader = new StreamReader(new FileStreamReader());

here, FileStreamReader() is upcasted to streadm reder.

Downcasting:

Shape s = new Circle(); here as explained above, view of s is the only parent, in order to make it for both parent and a child we need to downcast it

var c = (Circle) s;

The practical example of Downcasting is button class of WPF.

It may be more useful to use a http client library like such as this

There are more things like access denied , document moved etc to handle when dealing with http.

(though, it is unlikely in this case)

You also can set the width of a audio tag by JavaScript:

audio = document.getElementById('audio-id');
audio.style.width = '200px';

Was fiddling round with someone elses code today and found the following which seems rounds down as well:

var dec = 12.3453465,
int = dec >> 0; // returns 12

For more info on the Sign-propagating right shift(>>) see MDN Bitwise Operators

It took me a while to work out what this was doing :D

But as highlighted above, Math.floor() works and looks more readable in my opinion.

In Robins's answer ends-with is not supported in xpath 1.0 too.. Only starts-with is supported... So if your condition is not very specific..You can Use like this which worked for me

//*[starts-with(@id,'sometext') and contains(@name,'_text')]`\

If you want to call other api routes in the future and keep your token in the store then try using redux middleware.

The middleware could listen for the an api action and dispatch api requests through axios accordingly.

Here is a very basic example:

actions/api.js

export const CALL_API = 'CALL_API';

function onSuccess(payload) {
  return {
    type: 'SUCCESS',
    payload
  };
}

function onError(payload) {
  return {
    type: 'ERROR',
    payload,
    error: true
  };
}

export function apiLogin(credentials) {
  return {
    onSuccess,
    onError,
    type: CALL_API,
    params: { ...credentials },
    method: 'post',
    url: 'login'
  };
}

middleware/api.js

import axios from 'axios';
import { CALL_API } from '../actions/api';

export default ({ getState, dispatch }) => next => async action => {
  // Ignore anything that's not calling the api
  if (action.type !== CALL_API) {
    return next(action);
  }

  // Grab the token from state
  const { token } = getState().session;

  // Format the request and attach the token.
  const { method, onSuccess, onError, params, url } = action;

  const defaultOptions = {
    headers: {
      Authorization: token ? `Token ${token}` : '',
    }
  };

  const options = {
    ...defaultOptions,
    ...params
  };

  try {
    const response = await axios[method](url, options);
    dispatch(onSuccess(response.data));
  } catch (error) {
    dispatch(onError(error.data));
  }

  return next(action);
};

This should work in almost all browsers:

var xhr=new XMLHttpRequest();
xhr.open("GET","https://12Me21.github.io/test.txt");
xhr.onload=function(){
    console.log(xhr.responseText);
}
xhr.send();

Additionally, there's the new Fetch API:

fetch("https://12Me21.github.io/test.txt")
.then( response => response.text() )
.then( text => console.log(text) )

Make a new folder inside htdocs and access it in browser.Like this or this. Always start Apache when you start working or check whether it has started (in Control panel of xampp).

var i = 0;_x000D_
var length = 10;_x000D_
_x000D_
function for1() {_x000D_
  console.log(i);_x000D_
  for2();_x000D_
}_x000D_
_x000D_
function for2() {_x000D_
  if (i == length) {_x000D_
    return false;_x000D_
  }_x000D_
  setTimeout(function() {_x000D_
    i++;_x000D_
    for1();_x000D_
  }, 500);_x000D_
}_x000D_
for1();

Here is a sample functional approach to what is expected here.

For those who are getting the "Unable to resolve dependencies" error:

After searching an testing alot of solution for prevent sqlmap from sql injection, in case of legacy system which cant apply prepared statments every where.

java-security-cross-site-scripting-xss-and-sql-injection topic WAS THE SOLUTION

i tried @Richard s solution but did not work in my case. i used a filter

The goal of this filter is to wrapper the request into an own-coded wrapper MyHttpRequestWrapper which transforms:

the HTTP parameters with special characters (<, >, ‘, …) into HTML codes via the org.springframework.web.util.HtmlUtils.htmlEscape(…) method. Note: There is similar classe in Apache Commons : org.apache.commons.lang.StringEscapeUtils.escapeHtml(…) the SQL injection characters (‘, “, …) via the Apache Commons classe org.apache.commons.lang.StringEscapeUtils.escapeSql(…)

Yes, it is extremely useful in browsers that support it, but the "limiting" is as a convenience to users (so they are not overwhelmed with irrelevant files) rather than as a way to prevent them from uploading things you don't want them uploading.

It is supported in

• Chrome 16 +
• Safari 6 +
• Firefox 9 +
• IE 10 +
• Opera 11 +

Below settings are worked well for me,

"editor.insertSpaces": false,
"editor.formatOnSave": true, // only if you want auto fomattting on saving the file
"editor.detectIndentation": false

Above settings will reflect and applied to every files. You don't need to indent/format every file manually.

• System.Reflection.Assembly.GetEntryAssembly().Location returns location of exe name if assembly is not loaded from memory.
• System.Reflection.Assembly.GetEntryAssembly().CodeBase returns location as URL.

I have tried this code and it works well for both null and empty situations :

'<%# (Eval("item")=="" || Eval("item")==null) ? "0" : Eval("item")%>'

I note two usages which I couldn't find explicitly in the answers.

Grouping Class Items

Some developers use comments to separate different "parts" of their class. For example, a team might use the following convention:

public class MyClass{  
  //Member variables
  //Constructors
  //Properties
  //Methods
}

With partial classes, we can go a step further, and split the sections into separate files. As a convention, a team might suffix each file with the section corresponding to it. So in the above we would have something like: MyClassMembers.cs, MyClassConstructors.cs, MyClassProperties.cs, MyClassMethods.cs.

As other answers alluded to, whether or not it's worth splitting the class up probably depends on how big the class is in this case. If it's small, it's probably easier to have everything in one master class. But if any of those sections get too big, its content can be moved to a separate partial class, in order to keep the master class neat. A convention in that case might be to leave a comment in saying something like "See partial class" after the section heading e.g.:

//Methods - See partial class

Managing Scope of Using statements / Namespace

This is probably a rare occurrence, but there might be a namespace collision between two functions from libraries that you want to use. In a single class, you could at most use a using clause for one of these. For the other you'd need a fully qualified name or an alias. With partial classes, since each namespace & using statements list is different, one could separate the two sets of functions into two separate files.

I've investigated Slauma's answer (which is awesome, thanks for the idea man), and I've reduced batch size until I've hit optimal speed. Looking at the Slauma's results:

• commitCount = 1, recreateContext = true: more than 10 minutes
• commitCount = 10, recreateContext = true: 241 sec
• commitCount = 100, recreateContext = true: 164 sec
• commitCount = 1000, recreateContext = true: 191 sec

It is visible that there is speed increase when moving from 1 to 10, and from 10 to 100, but from 100 to 1000 inserting speed is falling down again.

So I've focused on what's happening when you reduce batch size to value somewhere in between 10 and 100, and here are my results (I'm using different row contents, so my times are of different value):

Quantity    | Batch size    | Interval
1000    1   3
10000   1   34
100000  1   368

1000    5   1
10000   5   12
100000  5   133

1000    10  1
10000   10  11
100000  10  101

1000    20  1
10000   20  9
100000  20  92

1000    27  0
10000   27  9
100000  27  92

1000    30  0
10000   30  9
100000  30  92

1000    35  1
10000   35  9
100000  35  94

1000    50  1
10000   50  10
100000  50  106

1000    100 1
10000   100 14
100000  100 141

Based on my results, actual optimum is around value of 30 for batch size. It's less than both 10 and 100. Problem is, I have no idea why is 30 optimal, nor could have I found any logical explanation for it.

You can get the url without parameters by using {{request.path}} You can get the url with parameters by using {{request.get_full_path}}

How about pass?

There's no way of getting around issue #2. That's just the way the C compiler (and hence the Objective-C compiler) work. If you use the XCode editor, the function popup should make it easy to navigate the @interface and @implementation blocks in the file.

There are many advantages of enums that are posted here, and I am creating such enums right now as asked in the question. But I have an enum with 5-6 fields.

enum Planet{
EARTH(1000000, 312312321,31232131, "some text", "", 12),
....
other planets
....

In these kinds of cases, when you have multiple fields in enums, it is much difficult to understand which value belongs to which field as you need to see constructor and eye-ball.

Class with static final constants and using Builder pattern to create such objects makes it more readable. But, you would lose all other advantages of using an enum, if you need them. One disadvantage of such classes is, you need to add the Planet objects manually to the list/set of Planets.

I still prefer enum over such class, as values() comes in handy and you never know if you need them to use in switch or EnumSet or EnumMap in future :)

• this.$el - points to the root element of the component
• this.$refs.<ref name> + <div ref="<ref name>" ... - points to nested element

use $el/$refs only after mounted() step of vue lifecycle

File myFile = new File(uri.toString());
myFile.getAbsolutePath()

should return u the correct path

EDIT

As @Tron suggested the working code is

File myFile = new File(uri.getPath());
myFile.getAbsolutePath()

include.prepload.js file will have a line something like below. probably as the last line.

//# sourceMappingURL=include.prepload.js.map

Delete it and the error will go away.

In Visual Studio 2019 WinForm Projects, it is available under

Project Properties -> Application -> View Windows Settings (button)

If you know the key which you unset then put directly by comma separated

unset($attr['placeholder'], $attr['autocomplete']);

just use this and feelfree:

#define BitVal(data,y) ( (data>>y) & 1)      /** Return Data.Y value   **/
#define SetBit(data,y)    data |= (1 << y)    /** Set Data.Y   to 1    **/
#define ClearBit(data,y)  data &= ~(1 << y)   /** Clear Data.Y to 0    **/
#define TogleBit(data,y)     (data ^=BitVal(y))     /** Togle Data.Y  value  **/
#define Togle(data)   (data =~data )         /** Togle Data value     **/

for example:

uint8_t number = 0x05; //0b00000101
uint8_t bit_2 = BitVal(number,2); // bit_2 = 1
uint8_t bit_1 = BitVal(number,1); // bit_1 = 0

SetBit(number,1); // number =  0x07 => 0b00000111
ClearBit(number,2); // number =0x03 => 0b0000011

SELECT 1 FROM user_right where userid = ? LIMIT 1

If your resultset contains a row then you do not have to insert. Otherwise insert your records.

The easiest way is to do:

chmod -R u+rwX,go+rX,go-w /path/to/dir

which basically means:

to change file modes -Recursively by giving:

• user: read, write and eXecute permissions,
• group and other users: read and eXecute permissions, but not -write permission.

Please note that X will make a directory executable, but not a file, unless it's already searchable/executable.

+X - make a directory or file searchable/executable by everyone if it is already searchable/executable by anyone.

Please check man chmod for more details.

Under HTML5 you are be able to do this:

document.getElementById('test').selectedOptions[0].text

MDN's documentation at https://developer.mozilla.org/en-US/docs/Web/API/HTMLSelectElement/selectedOptions indicates full cross-browser support (as of at least December 2017), including Chrome, Firefox, Edge and mobile browsers, but excluding Internet Explorer.

LINQ is very effective and easy to use on Lists rather than DataTable. I can see the above answers have a loop(for, foreach), which I will not prefer.

So the best thing to select a perticular column from a DataTable is just use a DataView to filter the column and use it as you want.

Find it here how to do this.

DataView dtView = new DataView(dtYourDataTable);
DataTable dtTableWithOneColumn= dtView .ToTable(true, "ColumnA");

Now the DataTable dtTableWithOneColumn contains only one column(ColumnA).

Found an answer myself, this blog helped: http://thingsyoudidntknowaboutjenkins.tumblr.com/post/23596855946/git-plugin-part-3

Basically need to execute:

git checkout master

before modifying any files

then

git commit -am "Updated version number"

after modified files

and then use post build action of Git Publisher with an option of Merge Results which will push changes to github on successful build.

You could do below:

select
iif ( OpeningBalance>=0 And OpeningBalance<=500 , 20, 

                  iif ( OpeningBalance>=5001 And OpeningBalance<=10000 , 30, 

                       iif ( OpeningBalance>=10001 And OpeningBalance<=20000 , 40, 

50 ) ) ) as commission
from table

What I do is give each one of my reusable component a unique custom element name and then create a CSS file for that component, specifically, with all styling options for that component (and only for that component).

var MyDiv = React.createClass({
  render: function() {
    return <custom-component style={style}> Have a good and productive day! </custom-component>;
  }
});

And in file 'custom-component.css', every entry will start with the custom-component tag:

custom-component { 
   display: block; /* have it work as a div */
   color: 'white'; 
   fontSize: 200; 
} 
custom-component h1 { 
  font-size: 1.4em; 
}

That means you don't lose the critical notion of separating of concern. View vs style. If you share your component, it is easier for others to theme it to match the rest of their web page.

for single condition, ie. ( 'employrate'] > 70 )

       country        employrate alcconsumption
0  Afghanistan  55.7000007629394            .03
1      Albania  51.4000015258789           7.29
2      Algeria              50.5            .69
3      Andorra                            10.17
4       Angola  75.6999969482422           5.57

use this:

df.loc[df['employrate'] > 70, 'employrate'] = 7

       country  employrate alcconsumption
0  Afghanistan   55.700001            .03
1      Albania   51.400002           7.29
2      Algeria   50.500000            .69
3      Andorra         nan          10.17
4       Angola    7.000000           5.57

therefore syntax here is:

df.loc[<mask>(here mask is generating the labels to index) , <optional column(s)> ]

For multiple conditions ie. (df['employrate'] <=55) & (df['employrate'] > 50)

use this:

df['employrate'] = np.where(
   (df['employrate'] <=55) & (df['employrate'] > 50) , 11, df['employrate']
   )

out[108]:
       country  employrate alcconsumption
0  Afghanistan   55.700001            .03
1      Albania   11.000000           7.29
2      Algeria   11.000000            .69
3      Andorra         nan          10.17
4       Angola   75.699997           5.57

therefore syntax here is:

 df['<column_name>'] = np.where((<filter 1> ) & (<filter 2>) , <new value>, df['column_name'])

Check it with a regex.

Javascript regexen don't have POSIX character classes, so you have to write character ranges manually:

if (!input_string.match(/^[0-9a-z]+$/))
  show_error_or_something()

Here ^ means beginning of string and $ means end of string, and [0-9a-z]+ means one or more of character from 0 to 9 OR from a to z.

More information on Javascript regexen here: https://developer.mozilla.org/en/JavaScript/Guide/Regular_Expressions

I've searched around, and only this solution helped me:

mysql -u root -p

set global net_buffer_length=1000000; --Set network buffer length to a large byte number

set global max_allowed_packet=1000000000; --Set maximum allowed packet size to a large byte number

SET foreign_key_checks = 0; --Disable foreign key checking to avoid delays,errors and unwanted behaviour

source file.sql --Import your sql dump file

SET foreign_key_checks = 1; --Remember to enable foreign key checks when procedure is complete!

The answer is found here.

If you are on RHEL and want a Red Hat supported Python, use Red Hat Software collections (RHSCL). The EPEL and IUS packages are not supported by Red Hat. Also many of the answers above point to the CentOS software collections. While you can install those, they aren't the Red Hat supported packages for RHEL.

Also, the top voted answer gives bad advice - On RHEL you do not want to change /usr/bin/python, /usr/bin/python2 because you will likely break yum and other RHEL admin tools. Take a look at /bin/yum, it is a Python script that starts with #!/usr/bin/python. If you compile Python from source, do not do a make install as root. That will overwrite /usr/bin/python. If you break yum it can be difficult to restore your system.

For more info, see How to install Python 3, pip, venv, virtualenv, and pipenv on RHEL on developers.redhat.com. It covers installing and using Python 3 from RHSCL, using Python Virtual Environments, and a number of tips for working with software collections and working with Python on RHEL.

In a nutshell, to install Python 3.6 via Red Hat Software Collections:

$ su -
# subscription-manager repos --enable rhel-7-server-optional-rpms \
   --enable rhel-server-rhscl-7-rpms
# yum -y install @development
# yum -y install rh-python36

# yum -y install rh-python36-numpy \
   rh-python36-scipy \ 
   rh-python36-python-tools \
   rh-python36-python-six

To use a software collection you have to enable it:

scl enable rh-python36 bash

However if you want Python 3 permanently enabled, you can add the following to your ~/.bashrc and then log out and back in again. Now Python 3 is permanently in your path.

# Add RHSCL Python 3 to my login environment
source scl_source enable rh-python36

Note: once you do that, typing python now gives you Python 3.6 instead of Python 2.7.

See the above article for all of this and a lot more detail.

I would just point out that... there are many kind of unordered_maps.

Look up the Wikipedia Article on hash map. Depending on which implementation was used, the characteristics in term of look-up, insertion and deletion might vary quite significantly.

And that's what worries me the most with the addition of unordered_map to the STL: they will have to choose a particular implementation as I doubt they'll go down the Policy road, and so we will be stuck with an implementation for the average use and nothing for the other cases...

For example some hash maps have linear rehashing, where instead of rehashing the whole hash map at once, a portion is rehash at each insertion, which helps amortizing the cost.

Another example: some hash maps use a simple list of nodes for a bucket, others use a map, others don't use nodes but find the nearest slot and lastly some will use a list of nodes but reorder it so that the last accessed element is at the front (like a caching thing).

So at the moment I tend to prefer the std::map or perhaps a loki::AssocVector (for frozen data sets).

Don't get me wrong, I'd like to use the std::unordered_map and I may in the future, but it's difficult to "trust" the portability of such a container when you think of all the ways of implementing it and the various performances that result of this.

I was getting this error

https://docs.google.com/file/d/0B-dUcqacTOLPcmI3SENMZFBLWG8/edit?usp=drivesdk

but I have done some coding into htdocs/index.php and made this like wamp homepage some thing like this

https://docs.google.com/file/d/0B-dUcqacTOLPVC1ORS1saGdOclU/edit?usp=drivesdk

On my case none of the above help to me. But, i downgrade NUNit3TestAdapter to version 3.8.0, then upgrade to the latest (3.10.0)

If you'd like the download to be offered as a download that can be opened directly in Excel, this may work for you: (copied from an old unreleased project of mine)

These functions setup the headers:

function setExcelContentType() {
    if(headers_sent())
        return false;

    header('Content-type: application/vnd.ms-excel');
    return true;
}

function setDownloadAsHeader($filename) {
    if(headers_sent())
        return false;

    header('Content-disposition: attachment; filename=' . $filename);
    return true;
}

This one sends a CSV to a stream using a mysql result

function csvFromResult($stream, $result, $showColumnHeaders = true) {
    if($showColumnHeaders) {
        $columnHeaders = array();
        $nfields = mysql_num_fields($result);
        for($i = 0; $i < $nfields; $i++) {
            $field = mysql_fetch_field($result, $i);
            $columnHeaders[] = $field->name;
        }
        fputcsv($stream, $columnHeaders);
    }

    $nrows = 0;
    while($row = mysql_fetch_row($result)) {
        fputcsv($stream, $row);
        $nrows++;
    }

    return $nrows;
}

This one uses the above function to write a CSV to a file, given by $filename

function csvFileFromResult($filename, $result, $showColumnHeaders = true) {
    $fp = fopen($filename, 'w');
    $rc = csvFromResult($fp, $result, $showColumnHeaders);
    fclose($fp);
    return $rc;
}

And this is where the magic happens ;)

function csvToExcelDownloadFromResult($result, $showColumnHeaders = true, $asFilename = 'data.csv') {
    setExcelContentType();
    setDownloadAsHeader($asFilename);
    return csvFileFromResult('php://output', $result, $showColumnHeaders);
}

For example:

$result = mysql_query("SELECT foo, bar, shazbot FROM baz WHERE boo = 'foo'");
csvToExcelDownloadFromResult($result);

you can use putExtra(Serializable..) and getSerializableExtra() methods to pass and retrieve objects of your class type; you will have to mark your class Serializable and make sure that all your member variables are serializable too...

imageview= (ImageView)findViewById(R.id.imageView);
imageview.setImageResource(R.drawable.mydrawable);

Updating to use tibble()

You can pass a named vector of length greater than 1 to the by argument of left_join():

library(dplyr)

d1 <- tibble(
  x = letters[1:3],
  y = LETTERS[1:3],
  a = rnorm(3)
  )

d2 <- tibble(
  x2 = letters[3:1],
  y2 = LETTERS[3:1],
  b = rnorm(3)
  )

left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))

To select (or remove) object properties that satisfy a given condition deeply, you can use something like this:

function pickByDeep(object, condition, arraysToo=false) {
  return _.transform(object, (acc, val, key) => {
    if (_.isPlainObject(val) || arraysToo && _.isArray(val)) {
      acc[key] = pickByDeep(val, condition, arraysToo);
    } else if (condition(val, key, object)) {
      acc[key] = val;
    }
  });
}

Simple and robust solution using the module pattern. This includes a fix for IE where the pathname does not always have a leading forward-slash (/).

I have created a Gist along with a JSFiddle which offers a more dynamic parser. I recommend you check it out and provide feedback.

var URLParser = (function (document) {
    var PROPS = 'protocol hostname host pathname port search hash href'.split(' ');
    var self = function (url) {
        this.aEl = document.createElement('a');
        this.parse(url);
    };
    self.prototype.parse = function (url) {
        this.aEl.href = url;
        if (this.aEl.host == "") {
           this.aEl.href = this.aEl.href;
        }
        PROPS.forEach(function (prop) {
            switch (prop) {
                case 'hash':
                    this[prop] = this.aEl[prop].substr(1);
                    break;
                default:
                    this[prop] = this.aEl[prop];
            }
        }, this);
        if (this.pathname.indexOf('/') !== 0) {
            this.pathname = '/' + this.pathname;
        }
        this.requestUri = this.pathname + this.search;

You could also disable the cascade delete convention in global scope of your application by doing this:

modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>()
modelBuilder.Conventions.Remove<ManyToManyCascadeDeleteConvention>()

If you're copying data like that, that probably means your datamodel isn't fully normalized, right? Is it possible to make one list of countries and do a JOIN more?

Instead of a JOIN you could also use virtual tables so you don't have to change the queries in your system.

The KeyTool is part of the JDK. You'll find it, assuming you installed the JDK with default settings, in $JAVA_HOME/bin

Have you googled about it - insert update delete access vb.net, there are lots of reference about this.

Insert Update Delete Navigation & Searching In Access Database Using VB.NET

• Create Visual Basic 2010 Project: VB-Access
• Assume that, we have a database file named data.mdb
• Place the data.mdb file into ..\bin\Debug\ folder (Where the project executable file (.exe) is placed)

what could be the easier way to connect and manipulate the DB?
Use OleDBConnection class to make connection with DB

is it by using MS ACCESS 2003 or MS ACCESS 2007?
you can use any you want to use or your client will use on their machine.

it seems that you want to find some example of opereations fo the database. Here is an example of Access 2010 for your reference:

I using "+" (plus) to insert div to html :

document.getElementById('idParent').innerHTML += '<div id="idChild"> content html </div>';

Hope this help.

You can try this:

HTML

<div class="social">
    <div class="socialIcon"><img src="images/facebook.png" alt="Facebook" /></div>
    <div class="socialText">Find me on Facebook</div>
</div>

CSS CODE

.social {
  width:330px;
  height:75px;
  float:right;
  text-align:left;
  padding:10px 0;
  border-bottom:dotted 1px #6d6d6d;
}
.social .socialIcon{
  padding-top:0;
}
.social .socialText{
  border:0;
}

To add multiple class in the same element you can use the following format:

<div class="class1 class2 class3"></div>

DEMO

This should work for you ...

int myInt= ((data)(((object[])(e.AddedItems))[0])).kid;

Nice solutions, but I wonder why nobody is giving the solution for windows.

If you are using windows you just have to "Run as Administrator" the cmd.

Try the following:

    NSString *birthday = @"06/15/1977";
    NSDateFormatter *formatter = [[NSDateFormatter alloc] init];
    [formatter setDateFormat:@"MM/dd/yyyy"];
    NSDate *date = [formatter dateFromString:birthday];
    if(date!=nil) {
        NSInteger age = [date timeIntervalSinceNow]/31556926;
        NSDateComponents *components = [[NSCalendar currentCalendar] components:NSCalendarUnitDay | NSCalendarUnitMonth | NSCalendarUnitYear fromDate:date];
        NSInteger day = [components day];
        NSInteger month = [components month];
        NSInteger year = [components year];

        NSLog(@"Day:%d Month:%d Year:%d Age:%d",day,month,year,age);
    }
    [formatter release];

Run cmd and then run node server.js. In your example, you are trying to use the REPL to run your command, which is not going to work. The ellipsis is node.js expecting more tokens before closing the current scope (you can type code in and run it on the fly here)

My preference is to use const whenever I can, which, as mentioned in previous answers, is limited to literal expressions or something that does not require evaluation.

If I hit up against that limitation, then I fallback to static readonly, with one caveat. I would generally use a public static property with a getter and a backing private static readonly field as Marc mentions here.

There are several file versions on the great Christoph Gohlke's site.

Something I have found important when installing wheels from this site is to first run this from the Python console:

import pip
print(pip.pep425tags.get_supported())

so that you know which version you should install for your computer. Picking the wrong version may fail the installing of the package (especially if you don't use the right CPython tag, for example, cp27).

if you get this error "Value does not fall within the expected range" in this line:

SPFolder myLibrary = oWeb.Folders[documentLibraryName];

use instead this to fix the error:

SPFolder myLibrary = oWeb.GetList(URL OR NAME).RootFolder;

Use always URl to get Lists or others because they are unique, names are not the best way ;)

Swift uses the same cocoa-touch API. You can call all the same methods, but they will use Swift's syntax. In this example you can do something like this:

self.simpleLabel.text = "message"

Note the setText method isn't available. Setting the label's text with = will automatically call the setter in swift.

In almost any language this should work instead:

a = true  && 5 || 10
a = false && 5 || 10

Here's the complete process in Kotlin:

the spinner adapter class:

class CustomSpinnerAdapter(
    context: Context,
    textViewResourceId: Int,
    val list: List<User>
) : ArrayAdapter<User>(
    context,
    textViewResourceId,
    list
) {
    override fun getCount() = list.size

    override fun getItem(position: Int) = list[position]

    override fun getItemId(position: Int) = list[position].report.toLong()

    override fun getView(position: Int, convertView: View?, parent: ViewGroup): View {
        return (super.getDropDownView(position, convertView, parent) as TextView).apply {
            text = list[position].name
        }
    }

    override fun getDropDownView(position: Int, convertView: View?, parent: ViewGroup): View {
        return (super.getDropDownView(position, convertView, parent) as TextView).apply {
            text = list[position].name
        }
    }
}

and use it in your activity/fragment like this:

spinner.adapter = CustomerSalesSpinnerAdapter(
            context,
            R.layout.cuser_spinner_item,
            userList
        )

Be careful with doing this manually.
In fact I would advise not doing this at all.

In reality we are talking about the line termination sequence LTS that is specific to platform.

If you open a file in text mode (ie not binary) then the streams will convert the "\n" into the correct LTS for your platform. Then convert the LTS back to "\n" when you read the file.

As a result if you print "\r\n" to a windows file you will get the sequence "\r\r\n" in the physical file (have a look with a hex editor).

Of course this is real pain when it comes to transferring files between platforms.

Now if you are writing to a network stream then I would do this manually (as most network protocols call this out specifically). But I would make sure the stream is not doing any interpretation (so binary mode were appropriate).

As an alternative to MailDefinition, have a look at RazorEngine https://github.com/Antaris/RazorEngine.

This looks like a better solution.

how to send email wth email template c#

E.g

using RazorEngine;
using RazorEngine.Templating;
using System;

namespace RazorEngineTest
{
    class Program
    {
        static void Main(string[] args)
        {
    string template =
    @"<h1>Heading Here</h1>
Dear @Model.UserName,
<br />
<p>First part of the email body goes here</p>";

    const string templateKey = "tpl";

    // Better to compile once
    Engine.Razor.AddTemplate(templateKey, template);
    Engine.Razor.Compile(templateKey);

    // Run is quicker than compile and run
    string output = Engine.Razor.Run(
        templateKey, 
        model: new
        {
            UserName = "Fred"
        });

    Console.WriteLine(output);
        }
    }
}

Which outputs...

<h1>Heading Here</h1>
Dear Fred,
<br />
<p>First part of the email body goes here</p>

Heading Here

Dear Fred,

First part of the email body goes here

I use Jena and I add the fellowing dependence to pom.xml

The official document

Id be inclined to create classes that match the structure and add an instance to a collection then serialise and deserialise the collection to load and save the document.

SELECT * FROM employees e1, employees e2 
WHERE e1.phoneNumber = e2.phoneNumber 
AND e1.id != e2.id;

Update : for better performance and faster query its good to add e1 before *

SELECT e1.* FROM employees e1, employees e2 
WHERE e1.phoneNumber = e2.phoneNumber 
AND e1.id != e2.id;

Firstly — I don't think column1 is not NULL or column1 <> '' makes very much sense. Maybe you meant to write column1 is not NULL and column1 <> '' (AND instead of OR)?

Secondly — because of Hive's "schema on read" approach to table definitions, invalid values will be converted to NULL when you read from them. So, for example, if table1.column1 is of type STRING and table2.column1 is of type INT, then I don't think that table1.column1 IS NOT NULL is enough to guarantee that table2.column1 IS NOT NULL. (I'm not sure about this, though.)

namedtuple is a tuple

>>> node = namedtuple('node', "a b")
>>> node(1,2) + node(5,6)
(1, 2, 5, 6)
>>> (node(1,2), node(5,6))
(node(a=1, b=2), node(a=5, b=6))
>>> 

Some more experiments to respond to comments:

>>> from collections import namedtuple
>>> from operator import *
>>> mytuple = namedtuple('A', "a b")
>>> yourtuple = namedtuple('Z', "x y")
>>> mytuple(1,2) + yourtuple(5,6)
(1, 2, 5, 6)
>>> q = [mytuple(1,2), yourtuple(5,6)]
>>> q
[A(a=1, b=2), Z(x=5, y=6)]
>>> reduce(operator.__add__, q)
(1, 2, 5, 6)

So, namedtuple is an interesting subtype of tuple.

Since this is most popular question with regard to this problem, I'll re-post another answer to it here as well:

It looks like there is simpler way to do this (but only in MySQL):

select *
from (select * from mytable order by id, rev desc ) x
group by id

Please credit answer of user Bohemian in this question for providing such a concise and elegant answer to this problem.

Edit: though this solution works for many people it may not be stable in the long run, since MySQL doesn't guarantee that GROUP BY statement will return meaningful values for columns not in GROUP BY list. So use this solution at your own risk!

You can use dirname:

os.path.dirname(path)

Return the directory name of pathname path. This is the first element of the pair returned by passing path to the function split().

And given the full path, then you can split normally to get the last portion of the path. For example, by using basename:

os.path.basename(path)

Return the base name of pathname path. This is the second element of the pair returned by passing path to the function split(). Note that the result of this function is different from the Unix basename program; where basename for '/foo/bar/' returns 'bar', the basename() function returns an empty string ('').

All together:

>>> import os
>>> path=os.path.dirname("C:/folder1/folder2/filename.xml")
>>> path
'C:/folder1/folder2'
>>> os.path.basename(path)
'folder2'

Keep in mind that docker ps --size may be an expensive command, taking more than a few minutes to complete. The same applies to container list API requests with size=1. It's better not to run it too often.

Take a look at alternatives we compiled, including the du -hs option for the docker persistent volume directory.

The way to check for null is to check for it:

DataRow[] myResultSet = myDataTable.Select("[COLUMN NAME] is null");

You can use and and or in the Select statement.

Thou the above answer is widely accepted and well documented, I found some of the reason to post my answer here :-

    doNothing().when(InternalUtils.class); //This is the preferred way
                                           //to mock static void methods.
    InternalUtils.sendEmail(anyString(), anyString(), anyString(), anyString());

Here, I dont understand why we are calling InternalUtils.sendEmail ourself. I will explain in my code why we don't need to do that.

mockStatic(Internalutils.class);

So, we have mocked the class which is fine. Now, lets have a look how we need to verify the sendEmail(/..../) method.

@PrepareForTest({InternalService.InternalUtils.class})
@RunWith(PowerMockRunner.class)
public class InternalServiceTest {

    @Mock
    private InternalService.Order order;

    private InternalService internalService;

    @Before
    public void setup() {
        MockitoAnnotations.initMocks(this);
        internalService = new InternalService();
    }

    @Test
    public void processOrder() throws Exception {

        Mockito.when(order.isSuccessful()).thenReturn(true);
        PowerMockito.mockStatic(InternalService.InternalUtils.class);

        internalService.processOrder(order);

        PowerMockito.verifyStatic(times(1));
        InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());
    }

}

These two lines is where the magic is, First line tells the PowerMockito framework that it needs to verify the class it statically mocked. But which method it need to verify ?? Second line tells which method it needs to verify.

PowerMockito.verifyStatic(times(1));
InternalService.InternalUtils.sendEmail(anyString(), any(String[].class), anyString(), anyString());

This is code of my class, sendEmail api twice.

public class InternalService {

    public void processOrder(Order order) {
        if (order.isSuccessful()) {
            InternalUtils.sendEmail("", new String[1], "", "");
            InternalUtils.sendEmail("", new String[1], "", "");
        }
    }

    public static class InternalUtils{

        public static void sendEmail(String from, String[]  to, String msg, String body){

        }

    }

    public class Order{

        public boolean isSuccessful(){
            return true;
        }

    }

}

As it is calling twice you just need to change the verify(times(2))... that's all.

"Sleep" state connections are most often created by code that maintains persistent connections to the database.

This could include either connection pools created by application frameworks, or client-side database administration tools.

As mentioned above in the comments, there is really no reason to worry about these connections... unless of course you have no idea where the connection is coming from.

(CAVEAT: If you had a long list of these kinds of connections, there might be a danger of running out of simultaneous connections.)

The code marked @Before is executed before each test, while @BeforeClass runs once before the entire test fixture. If your test class has ten tests, @Before code will be executed ten times, but @BeforeClass will be executed only once.

In general, you use @BeforeClass when multiple tests need to share the same computationally expensive setup code. Establishing a database connection falls into this category. You can move code from @BeforeClass into @Before, but your test run may take longer. Note that the code marked @BeforeClass is run as static initializer, therefore it will run before the class instance of your test fixture is created.

In JUnit 5, the tags @BeforeEach and @BeforeAll are the equivalents of @Before and @BeforeClass in JUnit 4. Their names are a bit more indicative of when they run, loosely interpreted: 'before each tests' and 'once before all tests'.

Use HTML's anchors:

Main Page:

<a href="sample.html#sushi">Sushi</a>
<a href="sample.html#bbq">BBQ</a>

Sample Page:

<div id='sushi'><a name='sushi'></a></div>
<div id='bbq'><a name='bbq'></a></div>

I'll generalize the problem and the Question as intended. Test assingment on the array, and catch the eventual error

Function IsVarArrayEmpty(anArray as Variant)
Dim aVar as Variant

IsVarArrayEmpty=False
On error resume next
aVar=anArray(1)
If Err.number then '...still, it might not start at this index
    aVar=anArray(0)
    If Err.number then IsVarArrayEmpty=True ' neither 0 or 1 yields good assignment
EndIF
End Function

Sure it misses arrays with all negative indexes or all > 1... is that likely? in weirdland, yes.

You can use DDC (Domain Directory Controller). It is a new, easy to use, Java SDK. You don't even need to know LDAP to use it. It exposes an object-oriented API instead.

You can find it here.

For what it's worth, the ultimate shortcut:

In my .bash_profile I have alias push="git push origin HEAD", so whenever i type push I know I'm pushing to the current branch I'm on.

If you're using the mysql native driver (common since php 5.3), and the mysqli extension, you can accomplish this with an asynchronous query:

<?php

// Here's an example query that will take a long time to execute.
$sql = "
    select *
    from information_schema.tables t1
    join information_schema.tables t2
    join information_schema.tables t3
    join information_schema.tables t4
    join information_schema.tables t5
    join information_schema.tables t6
    join information_schema.tables t7
    join information_schema.tables t8
";

$mysqli = mysqli_connect('localhost', 'root', '');
$mysqli->query($sql, MYSQLI_ASYNC | MYSQLI_USE_RESULT);
$links = $errors = $reject = [];
$links[] = $mysqli;

// wait up to 1.5 seconds
$seconds = 1;
$microseconds = 500000;

$timeStart = microtime(true);

if (mysqli_poll($links, $errors, $reject, $seconds, $microseconds) > 0) {
    echo "query finished executing. now we start fetching the data rows over the network...\n";

The flags I'm giving to mysqli_query accomplish important things. It tells the client driver to enable asynchronous mode, while forces us to use more verbose code, but lets us use a timeout(and also issue concurrent queries if you want!). The other flag tells the client not to buffer the entire result set into memory.

By default, php configures its mysql client libraries to fetch the entire result set of your query into memory before it lets your php code start accessing rows in the result. This can take a long time to transfer a large result. We disable it, otherwise we risk that we might time out while waiting for the buffering to complete.

Note that there's two places where we need to check for exceeding a time limit:

• The actual query execution
• while fetching the results(data)

You can accomplish similar in the PDO and regular mysql extension. They don't support asynchronous queries, so you can't set a timeout on the query execution time. However, they do support unbuffered result sets, and so you can at least implement a timeout on the fetching of the data.

For many queries, mysql is able to start streaming the results to you almost immediately, and so unbuffered queries alone will allow you to somewhat effectively implement timeouts on certain queries. For example, a

select * from tbl_with_1billion_rows

can start streaming rows right away, but,

select sum(foo) from tbl_with_1billion_rows

needs to process the entire table before it can start returning the first row to you. This latter case is where the timeout on an asynchronous query will save you. It will also save you from plain old deadlocks and other stuff.

ps - I didn't include any timeout logic on the connection itself.
