I know this thread is little old, but would like to add my 2 cents. We had the same "connection reset" error right after our one of the releases.

The root cause was, our apache server was brought down for deployment. All our third party traffic goes thru apache and we were getting connection reset error because of it being down.

Your log indicates ClientAbortException, which occurs when your HTTP client drops the connection with the server and this happened before server could close the server socket Connection.

Your exception says it all "Connection reset". The connection between your java process and the db server was lost, which could have happened for almost any reason(like network issues). The SQLRecoverableException just means that its recoverable, but the root cause is connection reset.

There are a few different points here:

1. Where is the .npmrc file created.
2. How can you download private packages

Running npm config ls -l will show you all the implicit settings for npm, including what it thinks is the right place to put the .npmrc. But if you have never logged in (using npm login) it will be empty. Simply log in to create it.

Another thing is #2. You can actually do that by putting a .npmrc file in the NPM package's root. It will then be used by NPM when authenticating. It also supports variable interpolation from your shell so you could do stuff like this:

; Get the auth token to use for fetching private packages from our private scope
; see http://blog.npmjs.org/post/118393368555/deploying-with-npm-private-modules
; and also https://docs.npmjs.com/files/npmrc
//registry.npmjs.org/:_authToken=${NPM_TOKEN}

If you have installed openssl, you can use:

echo -n "foobar" | openssl dgst -sha256

For other algorithms you can replace -sha256 with -md4, -md5, -ripemd160, -sha, -sha1, -sha224, -sha384, -sha512 or -whirlpool.

I am thinking this may not be possible in Java because annotation and its parameters are resolved at compile time.

With Seam 2 http://seamframework.org/ you were able to resolve annotation parameters at runtime, with expression language inside double quotes.

In Seam 3 http://seamframework.org/Seam3/Solder, this feature is the module Seam Solder

As a supplementary to the two previous answers (of user "sudo rm -rf" and "Evan Mulawski"), if you don't want to do anything when your alert view is clicked, you can just allocate, show and release it. You don't have to declare the delegate protocol.

I had massive problems with getting any of those scripts to work with sending mail in powershell. Turned out you need to create an app-password for your gmail-account to authenticate in the script. Now it works flawlessly!

We can achieve the same using "Directive" in Angularjs.

            //Bind mousemove event to the element which will show tooltip
            $("#tooltip").mousemove(function(e) {
                //find X & Y coodrinates
                x = e.clientX,
                y = e.clientY;

                //Set tooltip position according to mouse position
                tooltipSpan.style.top = (y + 20) + 'px';
                tooltipSpan.style.left = (x + 20) + 'px';
            });

Problem - I was not able to connect to DB through sql developer.

Solution - First thing to note is that SQL Developer is only UI to access to your database. I need to connect remote database not the localhost so I need not to install the oracle 8i/9i. Only I need is oracle client to install. After installation it got the path in environment variable like C:\oracle\product\10.2.0\client_1\bin. Still I was not able to connect the db.

Things to be checked.

1. Listner/port should be up for the server IP where you want to connect.
2. you will be able to ping the server. go to cmd prompt. type ping server Ip then enter.
3. telnet the server IP and port. should be succesful.

If all points are ok for you then check from where you are running sql developer .exe file. I pasted sql developer folder to C:\oracle folder and run the .exe file from here and I am able to connect the database. and my problem of 'IO Error: The Network Adapter could not establish the connection' got resolved. Hurrey... :) :)

Imagine you have this array below:

var arr = [1,2,3,4,5];

Javascript (new and older browsers):

function isArray(arr) {
  return arr.constructor.toString().indexOf("Array") > -1;
}

or

function isArray(arr) {
  return arr instanceof Array;
}

or

function isArray(arr) {
  return Object.prototype.toString.call(arr) === '[object Array]';
}

then call it like this:

isArray(arr);

Javascript (IE9+, Ch5+, FF4+, Saf5+, Opera10.5+)

Array.isArray(arr);

jQuery:

$.isArray(arr);

Angular:

angular.isArray(arr);

Underscore and Lodash:

_.isArray(arr);

In my case , I got this Error in Tensorflow , Reason was i was trying to feed a array with different length or sequences :

example :

import tensorflow as tf

input_x = tf.placeholder(tf.int32,[None,None])



word_embedding = tf.get_variable('embeddin',shape=[len(vocab_),110],dtype=tf.float32,initializer=tf.random_uniform_initializer(-0.01,0.01))

embedding_look=tf.nn.embedding_lookup(word_embedding,input_x)

with tf.Session() as tt:
    tt.run(tf.global_variables_initializer())

    a,b=tt.run([word_embedding,embedding_look],feed_dict={input_x:example_array})
    print(b)

And if my array is :

example_array = [[1,2,3],[1,2]]

Then i will get error :

ValueError: setting an array element with a sequence.

but if i do padding then :

example_array = [[1,2,3],[1,2,0]]

Now it's working.

I would like to point out that the solutions given above do not "just work" with non-trivial queries. One issue I came across were more complicated types, such as pgsql ARRAYs causing issues. I did find a solution that for me, did just work even with pgsql ARRAYs:

The linked code seems to be based on an older version of SQLAlchemy. You'll get an error saying that the attribute _mapper_zero_or_none doesn't exist. Here's an updated version that will work with a newer version, you simply replace _mapper_zero_or_none with bind. Additionally, this has support for pgsql arrays:

Given that today (was not available when this question was made) lots of people use Jupyter Notebook as python console, there is an extremely easy way to save the plots as .png, just call the matplotlib's pylab class from Jupyter Notebook, plot the figure 'inline' jupyter cells, and then drag that figure/image to a local directory. Don't forget %matplotlib inline in the first line!

Either use the

$(document).on "page:load", attachRatingHandler

or use jQuery's .on function to achieve the same effect

$(document).on 'click', 'span.star', attachRatingHandler

If you use String concatenation in a loop, something like this,

String s = "";
for (int i = 0; i < 100; i++) {
    s += ", " + i;
}

then you should use a StringBuilder (not StringBuffer) instead of a String, because it is much faster and consumes less memory.

If you have a single statement,

String s = "1, " + "2, " + "3, " + "4, " ...;

then you can use Strings, because the compiler will use StringBuilder automatically.

This is not possible with the magic find methods. Try using the query builder:

$result = $em->getRepository("Orders")->createQueryBuilder('o')
   ->where('o.OrderEmail = :email')
   ->andWhere('o.Product LIKE :product')
   ->setParameter('email', '[email protected]')
   ->setParameter('product', 'My Products%')
   ->getQuery()
   ->getResult();

Beware of auto imports. my HTTP_INTERCEPTORS was auto imported like this:

import { HTTP_INTERCEPTORS } from '@angular/common/http/src/interceptor';

instead of

import { HTTP_INTERCEPTORS } from '@angular/common/http';

which caused this error

The solution for me was to unblock the assembly DLLs. The error messages you get don't indicate this, but the XAML designer refuses to load what it calls "sandboxed" assemblies. You can see this in the output window when you build. DLLs are blocked if they are downloaded from the internet. To unblock your 3rd-party assembly DLLs:

1. Right click on the DLL file in Windows Explorer and select Properties.
2. At the bottom of the General tab click the "Unblock" button or checkbox.

Note: Only unblock DLLs if you are sure they are safe.

Mirroring a repository

Create a bare clone of the repository.

git clone --bare https://github.com/exampleuser/old-repository.git

Mirror-push to the new repository.

cd old-repository.git
git push --mirror https://github.com/exampleuser/new-repository.git

Remove the temporary local repository you created in step 1.

cd ..
rm -rf old-repository.git

Mirroring a repository that contains Git Large File Storage objects

Create a bare clone of the repository. Replace the example username with the name of the person or organization who owns the repository, and replace the example repository name with the name of the repository you'd like to duplicate.

git clone --bare https://github.com/exampleuser/old-repository.git

Navigate to the repository you just cloned.

cd old-repository.git

Pull in the repository's Git Large File Storage objects.

git lfs fetch --all

Mirror-push to the new repository.

git push --mirror https://github.com/exampleuser/new-repository.git

Push the repository's Git Large File Storage objects to your mirror.

git lfs push --all https://github.com/exampleuser/new-repository.git

Remove the temporary local repository you created in step 1.

cd ..
rm -rf old-repository.git

Above instruction comes from Github Help: https://help.github.com/articles/duplicating-a-repository/

After you fetch the first 50 rows in the query windows, simply click on any column to get focus on the query window, then once selected do ctrl + end key

This will load the full result set (all rows)

That's a rather large question.

LDAP is a protocol for accessing a directory. A directory contains objects; generally those related to users, groups, computers, printers and so on; company structure information (although frankly you can extend it and store anything in there).

LDAP gives you query methods to add, update and remove objects within a directory (and a bunch more, but those are the central ones).

What LDAP does not do is provide a database; a database provides LDAP access to itself, not the other way around. It is much more than signup.

This webpage may be useful and time-saving when working with .gitignore.

It automatically generates .gitignore files for different IDEs and operating systems with the specific files/folders that you usually don't want to pull to your Git repository (for instance, IDE-specific folders and configuration files).

The problem with all these solutions is that the height of the iframe never really changes.

This means you won't be able to center elements inside the iframe using Javascript, position:fixed;, or position:absolute; since the iframe itself never scrolls.

My solution detailed here is to wrap all the content of the iframe inside a div using this CSS:

#wrap {
    position: fixed;
    top: 0;
    right:0;
    bottom:0;
    left: 0;
    overflow-y: scroll;
    -webkit-overflow-scrolling: touch;
}

This way Safari believes the content has no height and lets you assign the height of the iframe properly. This also allows you to position elements in any way you wish.

You can see a quick and dirty demo here.

GhostScript performs much faster than Poppler for a Linux based system.

Following is the code for pdf to image conversion.

def get_image_page(pdf_file, out_file, page_num):
    page = str(page_num + 1)
    command = ["gs", "-q", "-dNOPAUSE", "-dBATCH", "-sDEVICE=png16m", "-r" + str(RESOLUTION), "-dPDFFitPage",
               "-sOutputFile=" + out_file, "-dFirstPage=" + page, "-dLastPage=" + page,
               pdf_file]
    f_null = open(os.devnull, 'w')
    subprocess.call(command, stdout=f_null, stderr=subprocess.STDOUT)

GhostScript can be installed on macOS using brew install ghostscript

Installation information for other platforms can be found here. If it is not already installed on your system.

You can use iteritems():

for name, values in df.iteritems():
    print('{name}: {value}'.format(name=name, value=values[0]))

You could actually use xlsread to accomplish this. After first placing your sample data above in a file 'input_file.csv', here is an example for how you can get the numeric values, text values, and the raw data in the file from the three outputs from xlsread:

>> [numData,textData,rawData] = xlsread('input_file.csv')

numData =     % An array of the numeric values from the file

   51.9358    4.1833
   51.9354    4.1841
   51.9352    4.1846
   51.9343    4.1864
   51.9343    4.1864
   51.9341    4.1869


textData =    % A cell array of strings for the text values from the file

    'ABC'
    'ABC'
    'ABC'
    'ABC'
    'ABC'
    'ABC'


rawData =     % All the data from the file (numeric and text) in a cell array

    'ABC'    [51.9358]    [4.1833]
    'ABC'    [51.9354]    [4.1841]
    'ABC'    [51.9352]    [4.1846]
    'ABC'    [51.9343]    [4.1864]
    'ABC'    [51.9343]    [4.1864]
    'ABC'    [51.9341]    [4.1869]

You can then perform whatever processing you need to on the numeric data, then resave a subset of the rows of data to a new file using xlswrite. Here's an example:

index = sqrt(sum(numData.^2,2)) >= 50;  % Find the rows where the point is
                                        %   at a distance of 50 or greater
                                        %   from the origin
xlswrite('output_file.csv',rawData(index,:));  % Write those rows to a new file

If you have a Red Hat server use yum. apt-get is only for Debian, Ubuntu and some other related linux.

Why would you want to use apt-get anyway? (It seems like you know what yum is.)

Making @sulai suggestion more generic :

@TargetApi(Build.VERSION_CODES.HONEYCOMB) // API 11
public static <T> void executeAsyncTask(AsyncTask<T, ?, ?> asyncTask, T... params) {
    if(Build.VERSION.SDK_INT >= Build.VERSION_CODES.HONEYCOMB)
        asyncTask.executeOnExecutor(AsyncTask.THREAD_POOL_EXECUTOR, params);
    else
        asyncTask.execute(params);
}   

If you need to use the latest versions of SciPy rather than the packaged version, without going through the hassle of building BLAS and LAPACK, you can follow the below procedure.

Install linear algebra libraries from repository (for Ubuntu),

sudo apt-get install gfortran libopenblas-dev liblapack-dev

Then install SciPy, (after downloading the SciPy source): python setup.py install or

pip install scipy

As the case may be.

An ioctl, which means "input-output control" is a kind of device-specific system call. There are only a few system calls in Linux (300-400), which are not enough to express all the unique functions devices may have. So a driver can define an ioctl which allows a userspace application to send it orders. However, ioctls are not very flexible and tend to get a bit cluttered (dozens of "magic numbers" which just work... or not), and can also be insecure, as you pass a buffer into the kernel - bad handling can break things easily.

An alternative is the sysfs interface, where you set up a file under /sys/ and read/write that to get information from and to the driver. An example of how to set this up:

static ssize_t mydrvr_version_show(struct device *dev,
        struct device_attribute *attr, char *buf)
{
    return sprintf(buf, "%s\n", DRIVER_RELEASE);
}

static DEVICE_ATTR(version, S_IRUGO, mydrvr_version_show, NULL);

And during driver setup:

device_create_file(dev, &dev_attr_version);

You would then have a file for your device in /sys/, for example, /sys/block/myblk/version for a block driver.

Another method for heavier use is netlink, which is an IPC (inter-process communication) method to talk to your driver over a BSD socket interface. This is used, for example, by the WiFi drivers. You then communicate with it from userspace using the libnl or libnl3 libraries.

I had the same problem. In my case it arises, because the lookup-table "country" has an existing record with countryId==0 and a primitive primary key and I try to save a User with a countryID==0. Change the primary key of country to Integer. Now Hibernate can identify new records.

For the recommendation of using wrapper classes as primary key see this stackoverflow question

Better to always download as your first try, the most recent version from the developer's site

I had the same error message you had, and by downloading the jar from the above (slf4j-1.7.2.tar.gz most recent version as of 2012OCT13), untarring, uncompressing, adding 2 jars to build path in eclipse (or adding to classpath in comand line):

1. slf4j-api-1.7.2.jar
2. slf4j-simple-1.7.2.jar

I was able to run my program.

Imagine that this is your Json response

{"Visit":{"VisitId":8,"Description":"visit8"}}

This is how you parse the response and access the values

    Ext.Ajax.request({
    headers: {
        'Content-Type': 'application/json'
    },
    url: 'api/fullvisit/getfullvisit/' + visitId,
    method: 'GET',
    dataType: 'json',
    success: function (response, request) {
        obj = JSON.parse(response.responseText);
        alert(obj.Visit.VisitId);
    }
});

This will alert the VisitId field

In a query you can just do something like:

SELECT ColumnA * ColumnB FROM table

or

SELECT ColumnA - ColumnB FROM table

You can also create computed columns in your table where you can permanently use your formula.

Just two steps needed:

1. Apply setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_LANDSCAPE); after setContentView().

2. In the AndroidMainfest.xml, put this statement <activity android:name=".YOURCLASSNAME" android:screenOrientation="landscape" />

Hope it helps and happy coding :)

In addition to the previous response, the best option to submit a form with different buttons without language problems is actually using a button tag.

<form>
    ...
    <button type="submit" name="submit" value="servlet1">Go to 1st Servlet</button>
    <button type="submit" name="submit" value="servlet2">Go to 2nd Servlet</button>
</form>

Create .bat file:

start javaw -jar %*

And choose app default to open .jar with this .bat file.

Here is a solution that is easier than the command line adb solution (which does work). It is easier because it is more graphical and can be done from within Eclipse.

In Eclipse with Android device attached go to Window menu > Show View > Other ... use filter text "Windows" to pull up Android > Windows ... show this. The top item in the list is the current activity.

Another way to pull this up is by showing the "Hierarchy View" perspective, which by default will show the Windows window.

You can apply the style via javascript. This is the Js code below that applies the filter to the image with the ID theImage.

function invert(){
document.getElementById("theImage").style.filter="invert(100%)";
}

And this is the

<img id="theImage" class="img-responsive" src="http://i.imgur.com/1H91A5Y.png"></img>

Now all you need to do is call invert() We do this when the image is clicked.

function invert(){_x000D_
document.getElementById("theImage").style.filter="invert(100%)";_x000D_
}

<h4> Click image to invert </h4>_x000D_
_x000D_
<img id="theImage" class="img-responsive" src="http://i.imgur.com/1H91A5Y.png" onClick="invert()" ></img>

In your link function, do this:

// link function
function (scope, element, attrs) {
  var myEl = angular.element(element[0].querySelector('.list-scrollable'));
}

Also, in your link function, don't name your scope variable using a $. That is an angular convention that is specific to built in angular services, and is not something that you want to use for your own variables.

Make a jQuery function more flexible.

$.fn.scrollDown=function(){
    let el=$(this)
    el.scrollTop(el[0].scrollHeight)
}

$('div').scrollDown()

First, I thought:

"...In Microsoft SQL Server the SELECT...INTO automatically creates the new table whereas Oracle seems to require you to manually create it before executing the SELECT...INTO statement..."

But after manually generating a table, it still did not work, still showing the "missing keyword" error.

So I gave up this time and solved it by first manually creating the table, then using the "classic" SELECT statement:

INSERT INTO assignment_20081120 SELECT * FROM assignment;

Which worked as expected. If anyone come up with an explanaition on how to use the SELECT...INTO in a correct way, I would be happy!

I personally found Josh's jQuery-based answer above to be the best I saw, and worked perfectly for my application... of course, I was already using jQuery... I certainly wouldn't have included the whole jQ library just for that one purpose.

Cheers!

EDIT: OK... so mere seconds after posting this, I saw another answer just below mine (not sure if still below me after an edit) that said to use:

document.getElementById('your_element_ID_here').scrollIntoView();

This works perfectly and in so much less code than the jQuery version! I had no idea that there was a built-in function in JS called .scrollIntoView(), but there it is! So, if you want the fancy animation, go jQuery. Quick n' dirty... use this one!

Assigning Comparison to property value

JavaScript

You could assign the comparison of the property to "1"

obj["isChecked"] = (obj["isChecked"]==="1");

This only evaluates for a String value of "1" though. Other variables evaulate to false like an actual typeof number would be false. (i.e. obj["isChecked"]=1)

If you wanted to be indiscrimate about "1" or 1, you could use:

obj["isChecked"] = (obj["isChecked"]=="1");

Example Outputs

console.log(obj["isChecked"]==="1"); // true
console.log(obj["isChecked"]===1); // false
console.log(obj["isChecked"]==1); // true
console.log(obj["isChecked"]==="0"); // false
console.log(obj["isChecked"]==="Elephant"); // false

PHP

Same concept in PHP

$obj["isChecked"] = ($obj["isChecked"] == "1");

The same operator limitations as stated above for JavaScript apply.

Double Not

The 'double not' also works. It's confusing when people first read it but it works in both languages for integer/number type values. It however does not work in JavaScript for string type values as they always evaluate to true:

JavaScript

!!"1"; //true
!!"0"; //true
!!1; //true
!!0; //false
!!parseInt("0",10); // false

PHP

echo !!"1"; //true
echo !!"0"; //false
echo !!1; //true
echo !!0; //false

System is a class of java.lang package, out is an object of PrintStream class and also static data member of System class, print() and println() is an instance method of PrintStream class. it is provide soft output on console.

Following code gives intended results.

string text="some interesting text\nsome text that should be in the same line\r\nsome 
text should be in another line"
var results = text.Split(new[] {"\n","\r\n"}, StringSplitOptions.None);

Try this:

Using LinearLayout if you are using textview height and width match_parent You can set the gravity text to center and text alignment to center text horizontal if you are using textview height and width wrap_content then add gravity center attribute in your LinearLayout.

Thank you

You don't need to compile python for Mac/Windows/Linux. It is an interpreted language, so you simply need to have the Python interpreter installed on the system of your choice (it is available for all three platforms).

As for a GUI library that works cross platform, Python's Tk/Tcl widget library works very well, and I believe is sufficiently cross platform.

Tkinter is the python interface to Tk/Tcl

From the python project webpage:

Tkinter is not the only GuiProgramming toolkit for Python. It is however the most commonly used one, and almost the only one that is portable between Unix, Mac and Windows

This should work

SELECT EXTRACTVALUE(column_name, '/DCResponse/ContextData/Decision') FROM traptabclob;

I have assumed the ** were just for highlighting?

Units:

The amount of "neurons", or "cells", or whatever the layer has inside it.

It's a property of each layer, and yes, it's related to the output shape (as we will see later). In your picture, except for the input layer, which is conceptually different from other layers, you have:

• Hidden layer 1: 4 units (4 neurons)
• Hidden layer 2: 4 units
• Last layer: 1 unit

Shapes

Shapes are consequences of the model's configuration. Shapes are tuples representing how many elements an array or tensor has in each dimension.

Ex: a shape (30,4,10) means an array or tensor with 3 dimensions, containing 30 elements in the first dimension, 4 in the second and 10 in the third, totaling 30*4*10 = 1200 elements or numbers.

The input shape

What flows between layers are tensors. Tensors can be seen as matrices, with shapes.

In Keras, the input layer itself is not a layer, but a tensor. It's the starting tensor you send to the first hidden layer. This tensor must have the same shape as your training data.

Example: if you have 30 images of 50x50 pixels in RGB (3 channels), the shape of your input data is (30,50,50,3). Then your input layer tensor, must have this shape (see details in the "shapes in keras" section).

Each type of layer requires the input with a certain number of dimensions:

• Dense layers require inputs as (batch_size, input_size)
  • or (batch_size, optional,...,optional, input_size)
• 2D convolutional layers need inputs as:
  • if using channels_last: (batch_size, imageside1, imageside2, channels)
  • if using channels_first: (batch_size, channels, imageside1, imageside2)
• 1D convolutions and recurrent layers use (batch_size, sequence_length, features)
  • Details on how to prepare data for recurrent layers

Now, the input shape is the only one you must define, because your model cannot know it. Only you know that, based on your training data.

All the other shapes are calculated automatically based on the units and particularities of each layer.

Relation between shapes and units - The output shape

Given the input shape, all other shapes are results of layers calculations.

The "units" of each layer will define the output shape (the shape of the tensor that is produced by the layer and that will be the input of the next layer).

Each type of layer works in a particular way. Dense layers have output shape based on "units", convolutional layers have output shape based on "filters". But it's always based on some layer property. (See the documentation for what each layer outputs)

Let's show what happens with "Dense" layers, which is the type shown in your graph.

A dense layer has an output shape of (batch_size,units). So, yes, units, the property of the layer, also defines the output shape.

• Hidden layer 1: 4 units, output shape: (batch_size,4).
• Hidden layer 2: 4 units, output shape: (batch_size,4).
• Last layer: 1 unit, output shape: (batch_size,1).

Weights

Weights will be entirely automatically calculated based on the input and the output shapes. Again, each type of layer works in a certain way. But the weights will be a matrix capable of transforming the input shape into the output shape by some mathematical operation.

In a dense layer, weights multiply all inputs. It's a matrix with one column per input and one row per unit, but this is often not important for basic works.

In the image, if each arrow had a multiplication number on it, all numbers together would form the weight matrix.

Shapes in Keras

Earlier, I gave an example of 30 images, 50x50 pixels and 3 channels, having an input shape of (30,50,50,3).

Since the input shape is the only one you need to define, Keras will demand it in the first layer.

But in this definition, Keras ignores the first dimension, which is the batch size. Your model should be able to deal with any batch size, so you define only the other dimensions:

input_shape = (50,50,3)
    #regardless of how many images I have, each image has this shape        

Optionally, or when it's required by certain kinds of models, you can pass the shape containing the batch size via batch_input_shape=(30,50,50,3) or batch_shape=(30,50,50,3). This limits your training possibilities to this unique batch size, so it should be used only when really required.

Either way you choose, tensors in the model will have the batch dimension.

So, even if you used input_shape=(50,50,3), when keras sends you messages, or when you print the model summary, it will show (None,50,50,3).

The first dimension is the batch size, it's None because it can vary depending on how many examples you give for training. (If you defined the batch size explicitly, then the number you defined will appear instead of None)

Also, in advanced works, when you actually operate directly on the tensors (inside Lambda layers or in the loss function, for instance), the batch size dimension will be there.

• So, when defining the input shape, you ignore the batch size: input_shape=(50,50,3)
• When doing operations directly on tensors, the shape will be again (30,50,50,3)
• When keras sends you a message, the shape will be (None,50,50,3) or (30,50,50,3), depending on what type of message it sends you.

Dim

And in the end, what is dim?

If your input shape has only one dimension, you don't need to give it as a tuple, you give input_dim as a scalar number.

So, in your model, where your input layer has 3 elements, you can use any of these two:

• input_shape=(3,) -- The comma is necessary when you have only one dimension
• input_dim = 3

But when dealing directly with the tensors, often dim will refer to how many dimensions a tensor has. For instance a tensor with shape (25,10909) has 2 dimensions.

Defining your image in Keras

Keras has two ways of doing it, Sequential models, or the functional API Model. I don't like using the sequential model, later you will have to forget it anyway because you will want models with branches.

PS: here I ignored other aspects, such as activation functions.

With the Sequential model:

from keras.models import Sequential  
from keras.layers import *  

model = Sequential()    

#start from the first hidden layer, since the input is not actually a layer   
#but inform the shape of the input, with 3 elements.    
model.add(Dense(units=4,input_shape=(3,))) #hidden layer 1 with input

#further layers:    
model.add(Dense(units=4)) #hidden layer 2
model.add(Dense(units=1)) #output layer   

With the functional API Model:

from keras.models import Model   
from keras.layers import * 

#Start defining the input tensor:
inpTensor = Input((3,))   

#create the layers and pass them the input tensor to get the output tensor:    
hidden1Out = Dense(units=4)(inpTensor)    
hidden2Out = Dense(units=4)(hidden1Out)    
finalOut = Dense(units=1)(hidden2Out)   

#define the model's start and end points    
model = Model(inpTensor,finalOut)

Shapes of the tensors

Remember you ignore batch sizes when defining layers:

• inpTensor: (None,3)
• hidden1Out: (None,4)
• hidden2Out: (None,4)
• finalOut: (None,1)

Find the local IP address of computer A and find the port that your website is running on. Then from computer B open a web browser and go to IP:port. Example: 192.168.1.5:80 if computer A's IP is 192.168.1.5 and your website is running on port 80

$.each(myobject, function(key, element) {
    alert('key: ' + key + '\n' + 'value: ' + element);
});

This does the work for me. :)

Adding a class which inherits DbContext resolved my problem:

public class MyDbContext : DbContext { public MyDbContext() { } }

I tried several popular array_multisort() and usort() answers and none of them worked for me. The data just gets jumbled and the code is unreadable. Here's a quick a dirty solution. WARNING: Only use this if you're sure a rogue delimiter won't come back to haunt you later!

Let's say each row in your multi array looks like: name, stuff1, stuff2:

// Sort by name, pull the other stuff along for the ride
foreach ($names_stuff as $name_stuff) {
    // To sort by stuff1, that would be first in the contatenation
    $sorted_names[] = $name_stuff[0] .','. name_stuff[1] .','. $name_stuff[2];
}
sort($sorted_names, SORT_STRING);

Need your stuff back in alphabetical order?

foreach ($sorted_names as $sorted_name) {
    $name_stuff = explode(',',$sorted_name);
    // use your $name_stuff[0] 
    // use your $name_stuff[1] 
    // ... 
}

Yeah, it's dirty. But super easy, won't make your head explode.

You can use this and then you can add just a class form from bootstrap. ^{(does not matter which version)}

<div class="form-group">
 <label >Begin voorverkoop periode</label>
 <input type="date" name="bday" max="3000-12-31" 
        min="1000-01-01" class="form-control">
</div>
<div class="form-group">
 <label >Einde voorverkoop periode</label>
 <input type="date" name="bday" min="1000-01-01"
        max="3000-12-31" class="form-control">
</div>

Arrays have O(1) random access, but are really expensive to add stuff onto or remove stuff from.

Linked lists are really cheap to add or remove items anywhere and to iterate, but random access is O(n).

Random Samples and Permutations ina dataframe If it is in matrix form convert into data.frame use the sample function from the base package indexes = sample(1:nrow(df1), size=1*nrow(df1)) Random Samples and Permutations

I run netstat -nao | findstr 5037 in cmd.

As you see there is a process with id 3888. I kill it with taskkill /f /pid 3888 if you have more than one, kill all.

after that run adb with adb start-server, my adb run sucessfully.

Try > workdirectory/filename.txt

This would:

• truncate the file if it exists
• create if it doesn't exist

You can consider it equivalent to:

rm -f workdirectory/filename.txt; touch workdirectory/filename.txt

The simple answer is that you can't reliably log out of http-authentication.

The long answer:
Http-auth (like the rest of the HTTP spec) is meant to be stateless. So being "logged in" or "logged out" isn't really a concept that makes sense. The better way to see it is to ask, for each HTTP request (and remember a page load is usually multiple requests), "are you allowed to do what you're requesting?". The server sees each request as new and unrelated to any previous requests.

Browsers have chosen to remember the credentials you tell them on the first 401, and re-send them without the user's explicit permission on subsequent requests. This is an attempt at giving the user the "logged in/logged out" model they expect, but it's purely a kludge. It's the browser that's simulating this persistence of state. The web server is completely unaware of it.

So "logging out", in the context of http-auth is purely a simulation provided by the browser, and so outside the authority of the server.

Yes, there are kludges. But they break RESTful-ness (if that's of value to you) and they are unreliable.

If you absolutely require a logged-in/logged-out model for your site authentication, the best bet is a tracking cookie, with the persistence of state stored on the server in some manner (mysql, sqlite, flatfile, etc). This will require all requests to be evaluated, for instance, with PHP.

//checking duplicate elements in an array
var arr=[1,3,4,6,8,9,1,3,4,7];
var hp=new Map();
console.log(arr.sort());
var freq=0;
for(var i=1;i<arr.length;i++){
// console.log(arr[i-1]+" "+arr[i]);
if(arr[i]==arr[i-1]){
freq++;

}
else{
hp.set(arr[i-1],freq+1);
freq=0;
}
}
console.log(hp);

You can use the OpenSSL Command line tool. The following commands should do the trick

openssl pkcs12 -in client_ssl.pfx -out client_ssl.pem -clcerts

openssl pkcs12 -in client_ssl.pfx -out root.pem -cacerts

If you want your file to be password protected etc, then there are additional options.

You can read the entire documentation here.

Try using %0A in the URL, just like you've used %20 instead of the space character.

change your query to like.

$username = mysql_real_escape_string($username); // escape string before passing it to query.
$query = mysql_query("SELECT username FROM Users WHERE username='".$username."'");

However, MySQL is deprecated. You should instead use MySQLi or PDO

From the comments, the problem was caused by using dlls that were built with Visual Studio 2013 in a project compiled with Visual Studio 2012. The reason for this was a third party library named the folders containing the dlls vc11, vc12. One has to be careful with any system that uses the compiler version (less than 4 digits) since this does not match the version of Visual Studio (except for Visual Studio 2010).

• vc8 = Visual Studio 2005
• vc9 = Visual Studio 2008
• vc10 = Visual Studio 2010
• vc11 = Visual Studio 2012
• vc12 = Visual Studio 2013
• vc14 = Visual Studio 2015
• vc15 = Visual Studio 2017
• vc16 = Visual Studio 2019

The Microsoft C++ runtime dlls use a 2 or 3 digit code also based on the compiler version not the version of Visual Studio.

• MSVCP80.DLL is from Visual Studio 2005
• MSVCP90.DLL is from Visual Studio 2008
• MSVCP100.DLL is from Visual Studio 2010
• MSVCP110.DLL is from Visual Studio 2012
• MSVCP120.DLL is from Visual Studio 2013
• MSVCP140.DLL is from Visual Studio 2015, 2017 and 2019

There is binary compatibility between Visual Studio 2015, 2017 and 2019.

Make sure to check the phpMyAdmin config file as well! On newer WAMP applications it is set to 128Mb by default. Even if you update php.ini to desired values you still need to update the phpmyadmin.conf!

Sample path: C:\wamp64\alias\phpmyadmin.conf

Or edit through your WAMP icon by: ->Apache -> Alias directories -> phpMyAdmin

* {
 font-size: 100%;

The asterisk implies all elements.

In my case I need to clear just the view and restart the controller. I could get my intention with this snippet:

$ionicHistory.clearCache([$state.current.name]).then(function() {
  $state.reload();
}

The cache still working and seems that just the view is cleared.

ionic --version says 1.7.5.

One clarification (and a point that confused me):

"remotes/origin/HEAD is the default branch" is not really correct.

remotes/origin/master was the default branch in the remote repository (last time you checked). HEAD is not a branch, it just points to a branch.

Think of HEAD as your working area. When you think of it this way then 'git checkout branchname' makes sense with respect to changing your working area files to be that of a particular branch. You "checkout" branch files into your working area. HEAD for all practical purposes is what is visible to you in your working area.

The error "client denied by server configuration" generally means that somewhere in your configuration are Allow from and Deny from directives that are preventing access. Read the mod_authz_host documentation for more details.

You should be able to solve this in your VirtualHost by adding something like:

<Location />
  Allow from all
  Order Deny,Allow
</Location>

Or alternatively with a Directory directive:

<Directory "D:/Devel/matysart/matysart_dev1">
  Allow from all
  Order Deny,Allow
</Directory>

Some investigation of your Apache configuration files will probably turn up default restrictions on the default DocumentRoot.

Java array reflection is for cases where you don't have an instance of the Class available to do "instanceof" on. For example, if you're writing some sort of injection framework, that injects values into a new instance of a class, such as JPA does, then you need to use the isArray() functionality.

I blogged about this earlier in December. http://blog.adamsbros.org/2010/12/08/java-array-reflection/

I wouldn't suggest using the Eclipse tool to generate the WS Client because I had bad experience with it:

I am not really sure if this matters but I had to consume a WS written in .NET. When I used the Eclipse's "New Web Service Client" tool it generated the Java classes using Axis (version 1.x) which as you can check is old (last version from 2006). There is a newer version though that is has some major changes but Eclipse doesn't use it.

Why the old version of Axis matters you'll say? Because when using OpenJDK you can run into some problems like missing cryptography algorithms in OpenJDK that are presented in the Oracle's JDK and some libraries like this one depend on them.

So I just used the wsimport tool and ended my headaches.

I am surprised that there's no concise answer yet, although such an expand/collapse animation is very easy to achieve with just 2 lines of code:

(recycler.itemAnimator as SimpleItemAnimator).supportsChangeAnimations = false // called once

together with

notifyItemChanged(position) // in adapter, whenever a child view in item's recycler gets hidden/shown

So for me, the explanations in the link below were really useful: https://medium.com/@nikola.jakshic/how-to-expand-collapse-items-in-recyclerview-49a648a403a6

Usually the process is the other way around. Do not go looking for situations where to use design patterns, look for code that can be optimized. When you have code that you think is not structured correctly. try to find a design pattern that will solve the problem.

Design patterns are meant to help you solve structural problems, do not go design your application just to be able to use design patterns.

Here I made a function to remove some parts of a datetime for SQL Server. Usage:

• First param is the datetime to be stripped off.
• Second param is a char:
  • s: rounds to seconds; removes milliseconds
  • m: rounds to minutes; removes seconds and milliseconds
  • h: rounds to hours; removes minutes, seconds and milliseconds.
  • d: rounds to days; removes hours, minutes, seconds and milliseconds.
• Returns the new datetime

create function dbo.uf_RoundDateTime(@dt as datetime, @part as char) returns datetime as begin if CHARINDEX( @part, 'smhd',0) = 0 return @dt; return cast( Case @part when 's' then convert(varchar(19), @dt, 126) when 'm' then convert(varchar(17), @dt, 126) + '00' when 'h' then convert(varchar(14), @dt, 126) + '00:00' when 'd' then convert(varchar(14), @dt, 112) end as datetime ) end

$res_arr_values = array();
while ($row = mysql_fetch_array($result, MYSQL_ASSOC))
{
    $res_arr_values[] = $row;
}


array_push == $res_arr_values[] = $row;

example 

<?php
$stack = array("orange", "banana");
array_push($stack, "apple", "raspberry");
print_r($stack);

Array
(
    [0] => orange
    [1] => banana
    [2] => apple
    [3] => raspberry
)
?>

On a native Windows install, you can either use batch(cmd.exe) or vbscript without the need to get external tools. Here's an example in vbscript:

Set objFS = CreateObject("Scripting.FileSystemObject")
strFile = "c:\test\file.txt"
Set objFile = objFS.OpenTextFile(strFile)
Do Until objFile.AtEndOfStream
    strLine = objFile.ReadLine
    If InStr(strLine,"ex3")> 0 Then
        strLine = Replace(strLine,"ex3","ex5")
    End If 
    WScript.Echo strLine
Loop    

Save as myreplace.vbs and on the command line:

c:\test> cscript /nologo myreplace.vbs  > newfile
c:\test> ren newfile file.txt

CSS Preprocessor integration for Angular CLI: 6.0.3

When generating a new project you can also define which extension you want for style files:

ng new sassy-project --style=sass

Or set the default style on an existing project:

ng config schematics.@schematics/angular:component.styleext scss

Try putting double quotes in your filepath variable

"\"E:/ABC/SEM 2/testfiles/all.txt\""

Check the permissions of the file or in any case consider renaming the folder to remove the space

I'm wondering whether you meant "recursive". Here is a simple example of a recursive function to compute the factorial function:

def factorial(n):
    if n == 0:
        return 1
    else:
        return n * factorial(n - 1)

The two key elements of a recursive algorithm are:

• The termination condition: n == 0
• The reduction step where the function calls itself with a smaller number each time: factorial(n - 1)

You need to parse the string you are sending from javascript object to the JSON object

var json=$.parseJSON(data);

You can, once you escape the HTML correctly. This page shows what needs to be done.

If using PHP, you could use json_encode()

Hope this helps :)

Canvas does not using .png file as background image. changing to other file extensions like gif or jpg works fine.

I would like to add that if you want to do this process automatically (download, stop and restart a new container with the same settings as described by @Yaroslav) you can use WatchTower. A program that auto updates your containers when they are changed https://github.com/v2tec/watchtower

Use PHP_EOL which outputs \r\n or \n depending on the OS.

Try this

function disable(i){
    $("#rbutton_"+i).attr("disabled",true);
}

If you really want to "ExecuteCall a shell script in current shell with sudo permission" you can use exec to...

replace the shell with a given program (executing it, not as new process)

I insist on replacing "execute" with "call" because the former has a meaning that includes creating a new process and ID, where the latter is ambiguous and leaves room for creativity, of which I am full.

Consider this test case and look closely at pid 1337

# Don't worry, the content of this script is cat'ed below
$ ./test.sh -o foo -p bar

User ubuntu is running...
 PID TT       USER     COMMAND
 775 pts/1    ubuntu   -bash
1408 pts/1    ubuntu    \_ bash ./test.sh -o foo -p bar
1411 pts/1    ubuntu        \_ ps -t /dev/pts/1 -fo pid,tty,user,args

User root is running...
 PID TT       USER     COMMAND
 775 pts/1    ubuntu   -bash
1337 pts/1    root      \_ sudo ./test.sh -o foo -p bar
1412 pts/1    root          \_ bash ./test.sh -o foo -p bar
1415 pts/1    root              \_ ps -t /dev/pts/1 -fo pid,tty,user,args

Take 'exec' out of the command and this script would get cat-ed twice. (Try it.)

#!/usr/bin/env bash

echo; echo "User $(whoami) is running..."
ps -t $(tty) -fo pid,tty,user,args

if [[ $EUID > 0 ]]; then
    # exec replaces the current process effectively ending execution so no exit is needed.
    exec sudo "$0" "$@"
fi

echo; echo "Take 'exec' out of the command and this script would get cat-ed twice. (Try it.)"; echo
cat $0

Here is another test using sudo -s

$ ps -fo pid,tty,user,args; ./test2.sh
  PID TT       USER     COMMAND
10775 pts/1    ubuntu   -bash
11496 pts/1    ubuntu    \_ ps -fo pid,tty,user,args

User ubuntu is running...
  PID TT       USER     COMMAND
10775 pts/1    ubuntu   -bash
11497 pts/1    ubuntu    \_ bash ./test2.sh
11500 pts/1    ubuntu        \_ ps -fo pid,tty,user,args

User root is running...
  PID TT       USER     COMMAND
11497 pts/1    root     sudo -s
11501 pts/1    root      \_ /bin/bash
11503 pts/1    root          \_ ps -fo pid,tty,user,args

$ cat test2.src
echo; echo "User $(whoami) is running..."
ps -fo pid,tty,user,args

$ cat test2.sh
#!/usr/bin/env bash

source test2.src

exec sudo -s < test2.src

And a simpler test using sudo -s

$ ./exec.sh
bash's PID:25194    user ID:7809
systemd(1)---bash(23064)---bash(25194)---pstree(25196)

Finally...
bash's PID:25199    user ID:0
systemd(1)---bash(23064)---sudo(25194)---bash(25199)---pstree(25201)

$ cat exec.sh
#!/usr/bin/env bash

pid=$$
id=$(id -u)
echo "bash's PID:$pid    user ID:$id"
pstree -ps $pid

# the quoted EOF is important to prevent shell expansion of the $...
exec sudo -s <<EOF
echo
echo "Finally..."
echo "bash's PID:\$\$    user ID:\$(id -u)"
pstree -ps $pid
EOF

For me its easier to use arrays than objects,

So, I convert an Xml-Object,

$xml = simplexml_load_file('xml_file.xml');    
$json_string = json_encode($xml);    
$result_array = json_decode($json_string, TRUE);

You need to be aware about how AngularJS works in order to understand it.

Digest cycle and $scope

First and foremost, AngularJS defines a concept of a so-called digest cycle. This cycle can be considered as a loop, during which AngularJS checks if there are any changes to all the variables watched by all the $scopes. So if you have $scope.myVar defined in your controller and this variable was marked for being watched, then you are implicitly telling AngularJS to monitor the changes on myVar in each iteration of the loop.

A natural follow-up question would be: Is everything attached to $scope being watched? Fortunately, no. If you would watch for changes to every object in your $scope, then quickly a digest loop would take ages to evaluate and you would quickly run into performance issues. That is why the AngularJS team gave us two ways of declaring some $scope variable as being watched (read below).

$watch helps to listen for $scope changes

There are two ways of declaring a $scope variable as being watched.

1. By using it in your template via the expression <span>{{myVar}}</span>
2. By adding it manually via the $watch service

Ad 1) This is the most common scenario and I'm sure you've seen it before, but you didn't know that this has created a watch in the background. Yes, it had! Using AngularJS directives (such as ng-repeat) can also create implicit watches.

Ad 2) This is how you create your own watches. $watch service helps you to run some code when some value attached to the $scope has changed. It is rarely used, but sometimes is helpful. For instance, if you want to run some code each time 'myVar' changes, you could do the following:

function MyController($scope) {

    $scope.myVar = 1;

    $scope.$watch('myVar', function() {
        alert('hey, myVar has changed!');
    });

    $scope.buttonClicked = function() {
        $scope.myVar = 2; // This will trigger $watch expression to kick in
    };
}

$apply enables to integrate changes with the digest cycle

You can think of the $apply function as of an integration mechanism. You see, each time you change some watched variable attached to the $scope object directly, AngularJS will know that the change has happened. This is because AngularJS already knew to monitor those changes. So if it happens in code managed by the framework, the digest cycle will carry on.

However, sometimes you want to change some value outside of the AngularJS world and see the changes propagate normally. Consider this - you have a $scope.myVar value which will be modified within a jQuery's $.ajax() handler. This will happen at some point in future. AngularJS can't wait for this to happen, since it hasn't been instructed to wait on jQuery.

To tackle this, $apply has been introduced. It lets you start the digestion cycle explicitly. However, you should only use this to migrate some data to AngularJS (integration with other frameworks), but never use this method combined with regular AngularJS code, as AngularJS will throw an error then.

How is all of this related to the DOM?

Well, you should really follow the tutorial again, now that you know all this. The digest cycle will make sure that the UI and the JavaScript code stay synchronised, by evaluating every watcher attached to all $scopes as long as nothing changes. If no more changes happen in the digest loop, then it's considered to be finished.

You can attach objects to the $scope object either explicitly in the Controller, or by declaring them in {{expression}} form directly in the view.

I hope that helps to clarify some basic knowledge about all this.

It seems like this is a pretty vague error, so I will share what I did to fix it when I ran into this:

Using Xcode 10.1 and Swift 4.2 I tried pretty much all the suggestions here but none of them worked for me, then I realized a dependency I was using was not compatible with Swift 4.2 and that was causing me to get this error on other pods. So to fix it I just had to force that pod to use Swift 4.0 by putting this at the end of my Podfile:

post_install do |installer|
    installer.pods_project.targets.each do |target|
        if ['TKRadarChart'].include? target.name
            target.build_configurations.each do |config|
                config.build_settings['SWIFT_VERSION'] = '4.0'
            end
        end
    end
end

Is this what you are looking for.

$("input.address_field").on('click', function(){  
     $(this).css('border', '2px solid red');
});

Ended up to have a file named polyfill.js in projectpath\src\polyfill.js That file only contains this line: import 'core-js'; this polyfills not only es-6, but is the correct way to use core-js since version 3.0.0.

I added the polyfill.js to my webpack-file entry attribute like this:

entry: ['./src/main.scss', './src/polyfill.js', './src/main.jsx']

Works perfectly.

I also found some more information here : https://github.com/zloirock/core-js/issues/184

The library author (zloirock) claims:

ES6 changes behaviour almost all features added in ES5, so core-js/es6 entry point includes almost all of them. Also, as you wrote, it's required for fixing broken browser implementations.

(Quotation https://github.com/zloirock/core-js/issues/184 from zloirock)

So I think import 'core-js'; is just fine.

You can use anonymous types for this, i.e.:

var pageObject = (from op in db.ObjectPermissions
                  join pg in db.Pages on op.ObjectPermissionName equals page.PageName
                  where pg.PageID == page.PageID
                  select new { pg, op }).SingleOrDefault();

This will make pageObject into an IEnumerable of an anonymous type so AFAIK you won't be able to pass it around to other methods, however if you're simply obtaining data to play with in the method you're currently in it's perfectly fine. You can also name properties in your anonymous type, i.e.:-

var pageObject = (from op in db.ObjectPermissions
                  join pg in db.Pages on op.ObjectPermissionName equals page.PageName
                  where pg.PageID == page.PageID
                  select new
                  {
                      PermissionName = pg, 
                      ObjectPermission = op
                  }).SingleOrDefault();

This will enable you to say:-

if (pageObject.PermissionName.FooBar == "golden goose") Application.Exit();

For example :-)

Best way to implement the selector is by using the xml instead of using programatic way as its more easy to implemnt with xml.

    <?xml version="1.0" encoding="utf-8"?>    
<selector xmlns:android="http://schemas.android.com/apk/res/android">
        <item android:drawable="@drawable/button_bg_selected" android:state_selected="true"></item>
        <item android:drawable="@drawable/button_bg_pressed" android:state_pressed="true"></item>
        <item android:drawable="@drawable/button_bg_normal"></item>

    </selector>

For more information i implemented using this link http://www.blazin.in/2016/03/how-to-use-selectors-for-botton.html

You can listen on whatever port you want; generally, user applications should listen to ports 1024 and above (through 65535). The main thing if you have a variable number of listeners is to allocate a range to your app - say 20000-21000, and CATCH EXCEPTIONS. That is how you will know if a port is unusable (used by another process, in other words) on your computer.

However, in your case, you shouldn't have a problem using a single hard-coded port for your listener, as long as you print an error message if the bind fails.

Note also that most of your sockets (for the slaves) do not need to be explicitly bound to specific port numbers - only sockets that wait for incoming connections (like your master here) will need to be made a listener and bound to a port. If a port is not specified for a socket before it is used, the OS will assign a useable port to the socket. When the master wants to respond to a slave that sends it data, the address of the sender is accessible when the listener receives data.

I presume you will be using UDP for this?

This answer is based on the solution given by Denis Nek. It solves the problem of not taking decorations like dividers into account.

Try this in the .htaccess of the external root folder

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "*"
</IfModule>

Be careful on : Header add Access-Control-Allow-Origin "*" This is not judicious at all to grant access to everybody. I think you should user:

<IfModule mod_headers.c>
    Header set Access-Control-Allow-Origin "http://example.com"

Select Into functionality only works for PL/SQL Block, when you use Execute immediate , oracle interprets v_query_str as a SQL Query string so you can not use into .will get keyword missing Exception. in example 2 ,we are using begin end; so it became pl/sql block and its legal.

You'll find the junit launch commands in .metadata/.plugins/org.eclipse.debug.core/.launches, assuming your Eclipse works like mine does. The files are named {TestClass}.launch.

You will probably also need the .classpath file in the project directory that contains the test class.

Like the run configurations, they're XML files (even if they don't have an xml extension).

Note that you have to be careful if your row contains a factor. Here is an example:

df_1 = data.frame(V1 = factor(11:15),
                  V2 = 21:25)
df_1[1,] %>% as.numeric() # you expect 11 21 but it returns 
[1] 1 21

Here is another example (by default data.frame() converts characters to factors)

df_2 = data.frame(V1 = letters[1:5],
                  V2 = 1:5)
df_2[3,] %>% as.numeric() # you expect to obtain c 3 but it returns
[1] 3 3
df_2[3,] %>% as.character() # this won't work neither
[1] "3" "3"

To prevent this behavior, you need to take care of the factor, before extracting it:

df_1$V1 = df_1$V1 %>% as.character() %>% as.numeric()
df_2$V1 = df_2$V1 %>% as.character()
df_1[1,] %>% as.numeric()
[1] 11  21
df_2[3,] %>% as.character()
[1] "c" "3"

You cannot insert data because you have a quota of 0 on the tablespace. To fix this, run

ALTER USER <user> quota unlimited on <tablespace name>;

or

ALTER USER <user> quota 100M on <tablespace name>;

as a DBA user (depending on how much space you need / want to grant).

It's declaring the string as nvarchar data type, rather than varchar

You may have seen Transact-SQL code that passes strings around using an N prefix. This denotes that the subsequent string is in Unicode (the N actually stands for National language character set). Which means that you are passing an NCHAR, NVARCHAR or NTEXT value, as opposed to CHAR, VARCHAR or TEXT.

To quote from Microsoft:

Prefix Unicode character string constants with the letter N. Without the N prefix, the string is converted to the default code page of the database. This default code page may not recognize certain characters.

If you want to know the difference between these two data types, see this SO post:

What is the difference between varchar and nvarchar?

I was crazy to delete node and npm and nodejs from my Ubuntu 14.04 but with this steps you will remove it:

sudo apt-get uninstall nodejs npm node
sudo apt-get remove nodejs npm node

If you uninstall correctly and it is still there, check these links:

• Stack Overflow answer with more information
• Remove npm - Official website
• Stack Overflow answer for uninstalling if you installed via git repository
• Try purging nodejs npm and node

You can also try using find:

find / -name "node"

Although since that is likely to take a long time and return a lot of confusing false positives, you may want to search only PATH locations:

find $(echo $PATH | sed 's/:/ /g') -name "node"

It would probably be in /usr/bin/node or /usr/local/bin. After finding it, you can delete it using the correct path, eg:

sudo rm /usr/bin/node

EF doesn't support unique columns except keys. If you are using EF Migrations you can force EF to create unique index on UserName column (in migration code, not by any annotation) but the uniqueness will be enforced only in the database. If you try to save duplicate value you will have to catch exception (constraint violation) fired by the database.

Instead of using loops and counting each element or using and third party library we can simply typecast the iterable in ArrayList and get its size.

((ArrayList) iterable).size();

e = ''
while e == '':
    try:
        response = ur.urlopen('https://https://raw.githubusercontent.com/MrMe42/Joe-Bot-Home-Assistant/mac/Joe.py')
        e = ' '
    except:
        print('Connection refused. Retrying...')
        time.sleep(1)

This should work. It sets e to '' and the while loop checks to see if it is still ''. If there is an error caught be the try statement, it prints that the connection was refused, waits 1 second and then starts over. It will keep going until there is no error in try, which then sets e to ' ', which kills the while loop.

List<String> list = Arrays.asList(array);

The list returned will be backed by the array, it acts like a bridge, so it will be fixed-size.

In fact, depends what you want to get: - Just the min value:

SELECT MIN(price) FROM pieces

• A table (multiples rows) whith the min value: Is as John Woo said above.

• But, if can be different rows with same min value, the best is ORDER them from another column, because after or later you will need to do it (starting from John Woo answere):

  SELECT * FROM pieces WHERE price = ( SELECT MIN(price) FROM pieces) ORDER BY stock ASC

You can go up a folder in the hierarchy by using

../

So to get to folder /webroot/site/pages/folder2/mypage.htm from /webroot/site/pages/folder1/myotherpage.htm your link would look like this:

<a href="../folder2/mypage.htm">Link to My Page</a>

I wrote once a tool for myself to do exactly that thing:

a7 SqlTools

It's free and open-source:

function listCookies() {
    let cookies = document.cookie.split(';')

}

function findCookie(e) {
  let cookies = document.cookie.split(';')
  cookies.map((cookie, n) => cookie.includes(e) && console.log(decodeURIComponent(cookie), n))
}

This is specifically for the window you're in. Tried to keep it clean and concise.

as much as everyone hates tables for layout, they do help with stuff like this, either using explicit table tags or using display:table-cell

<div style="width:300px; display:table">
    <label for="MyInput" style="display:table-cell; width:1px">label&nbsp;text</label>
    <input type="text" id="MyInput" style="display:table-cell; width:100%" />
</div>

Okay, redis is pretty user friendly but there are some gotchas.

Here are just some easy commands for working with redis on Ubuntu:

install:

sudo apt-get install redis-server

start with conf:

sudo redis-server <path to conf>
sudo redis-server config/redis.conf

stop with conf:

redis-ctl shutdown

(not sure how this shuts down the pid specified in the conf. Redis must save the path to the pid somewhere on boot)

log:

tail -f /var/log/redis/redis-server.log

Also, various example confs floating around online and on this site were beyond useless. The best, sure fire way to get a compatible conf is to copy-paste the one your installation is already using. You should be able to find it here:

/etc/redis/redis.conf

Then paste it at <path to conf>, tweak as needed and you're good to go.

According to Reddit, more options icon and kabob menu are popular names. I prefer the latter as it goes well with hamburger menu.

This is probably a configuration error. If you insist on using PHP mail function, you will have to edit php.ini.

If you are looking for an easier and more versatile option (in my opinion), you should use PHPMailer.

after generating XML you can just Replace your XML <Marks>... content here </Marks> tags with <SubjectMarks>... content here </SubjectMarks>tag. and pass updated XML to your DB.

Edit: I here explain complete process here.

Your XML Generate Like as below.

<NewDataSet>
      <StudentMarks> 
          <StudentID>1</StudentID>
          <CourseID>100</CourseID>
          <SubjectCode>MT400</SubjectCode>
          <Marks>80</Marks>
      </StudentMarks>
      <StudentMarks> 
          <StudentID>1</StudentID>
          <CourseID>100</CourseID>
          <SubjectCode>MT400</SubjectCode>
          <Marks>79</Marks>
      </StudentMarks>
      <StudentMarks> 
          <StudentID>1</StudentID>
          <CourseID>100</CourseID>
          <SubjectCode>MT400</SubjectCode>
          <Marks>88</Marks>
      </StudentMarks>
  </NewDataSet>

Here you can assign XML to string variable like as

string strXML = DataSet.GetXML();

strXML = strXML.Replace ("<Marks>","<SubjectMarks>");
strXML = strXML.Replace ("<Marks/>","<SubjectMarks/>");

and now pass strXML To your DB. Hope it will help for you.

In batch, the > is a redirection sign used to output data into a text file. The compare op's available (And recommended) for cmd are below (quoted from the if /? help):

where compare-op may be one of:

    EQU - equal
    NEQ - not equal
    LSS - less than
    LEQ - less than or equal
    GTR - greater than
    GEQ - greater than or equal

That should explain what you want. The only other compare-op is == which can be switched with the if not parameter. Other then that rely on these three letter ones.

You need %in% instead of ==:

library(dplyr)
target <- c("Tom", "Lynn")
filter(dat, name %in% target)  # equivalently, dat %>% filter(name %in% target)

Produces

  days name
1   88 Lynn
2   11  Tom
3    1  Tom
4  222 Lynn
5    2 Lynn

To understand why, consider what happens here:

dat$name == target
# [1] FALSE FALSE FALSE FALSE FALSE FALSE FALSE  TRUE

Basically, we're recycling the two length target vector four times to match the length of dat$name. In other words, we are doing:

 Lynn == Tom
  Tom == Lynn
Chris == Tom
 Lisa == Lynn
 ... continue repeating Tom and Lynn until end of data frame

In this case we don't get an error because I suspect your data frame actually has a different number of rows that don't allow recycling, but the sample you provide does (8 rows). If the sample had had an odd number of rows I would have gotten the same error as you. But even when recycling works, this is clearly not what you want. Basically, the statement dat$name == target is equivalent to saying:

return TRUE for every odd value that is equal to "Tom" or every even value that is equal to "Lynn".

It so happens that the last value in your sample data frame is even and equal to "Lynn", hence the one TRUE above.

To contrast, dat$name %in% target says:

for each value in dat$name, check that it exists in target.

Very different. Here is the result:

[1]  TRUE  TRUE FALSE FALSE FALSE  TRUE  TRUE  TRUE

Note your problem has nothing to do with dplyr, just the mis-use of ==.

Remote Procedure Call (RPC) is a inter process communication which allows calling a function in another process residing in local or remote machine.

Remote method invocation (RMI) is an API, which implements RPC in java with support of object oriented paradigms.

1. You can think of invoking RPC is like calling a C procedure. RPC supports primitive data types where as RMI support method parameters/return types as java objects.

2. RMI is easy to program unlike RPC. You can think your business logic in terms of objects instead of a sequence of primitive data types.

3. RPC is language neutral unlike RMI, which is limited to java

4. RMI is little bit slower to RPC

Have a look at this article for RPC implementation in C

You could also, in another directory:

• git clone [your repository]
• Overwrite the .git directory in your original repository with the .git directory of the repository you just cloned right now.
• git add and git commit your original

Dominc has the right idea, but put the calculation on the other side of the expression.

SELECT * FROM my_table WHERE endTime < DATE_SUB(CONVERT_TZ(NOW(), @@global.time_zone, 'GMT'), INTERVAL 30 MINUTE)

This has the advantage that you're doing the 30 minute calculation once instead of on every row. That also means MySQL can use the index on that column. Both of thse give you a speedup.

You can also get the value of an item in the jObject like this:

JToken value;
if (json.TryGetValue(key, out value))
{
   DoSomething(value);
}

SELECT student, (SUM(mark1)+SUM(mark2)+SUM(mark3)....+SUM(markn)) AS Total
 FROM your_table
 GROUP BY student

You can do something like this to check if any mysql process is running or not:

ps aux | grep mysqld
ps aux | grep mysql

Then if it is running you can killall by using(depending on what all processes are running currently):

killall -9 mysql
killall -9 mysqld
killall -9 mysqld_safe    

To follow up on the comment by suhendri to Rory McCrossan answer. Here is an Action delegate example:

In child add:

public Action UpdateProgress;  // In place of event handler declaration
                               // declare an Action delegate
.
.
.
private LoadData() {
    this.UpdateProgress();    // call to Action delegate - MyMethod in
                              // parent
}

In parent add:

// The 3 lines in the parent becomes:
ChildClass child = new ChildClass();
child.UpdateProgress = this.MyMethod;  // assigns MyMethod to child delegate

For user using PHP 5.6.x follow this link and install the x86 version.

Angular has a built-in filter for showing JSON

<pre>{{data | json}}</pre>

Note the use of the pre-tag to conserve whitespace and linebreaks

There's also an angular.toJson method, but I haven't played around with that (Docs)

I found it strangely difficult to locate the python docs for __enter__ and __exit__ methods by Googling, so to help others here is the link:

https://docs.python.org/2/reference/datamodel.html#with-statement-context-managers
https://docs.python.org/3/reference/datamodel.html#with-statement-context-managers
(detail is the same for both versions)

object.__enter__(self)
Enter the runtime context related to this object. The with statement will bind this method’s return value to the target(s) specified in the as clause of the statement, if any.

object.__exit__(self, exc_type, exc_value, traceback)
Exit the runtime context related to this object. The parameters describe the exception that caused the context to be exited. If the context was exited without an exception, all three arguments will be None.

If an exception is supplied, and the method wishes to suppress the exception (i.e., prevent it from being propagated), it should return a true value. Otherwise, the exception will be processed normally upon exit from this method.

Note that __exit__() methods should not reraise the passed-in exception; this is the caller’s responsibility.

I was hoping for a clear description of the __exit__ method arguments. This is lacking but we can deduce them...

Presumably exc_type is the class of the exception.

It says you should not re-raise the passed-in exception. This suggests to us that one of the arguments might be an actual Exception instance ...or maybe you're supposed to instantiate it yourself from the type and value?

We can answer by looking at this article:
http://effbot.org/zone/python-with-statement.htm

For example, the following __exit__ method swallows any TypeError, but lets all other exceptions through:

def __exit__(self, type, value, traceback):
    return isinstance(value, TypeError)

...so clearly value is an Exception instance.

And presumably traceback is a Python traceback object.

I don't know how stubhub's api works, but generally it should look like this:

s = requests.Session()
data = {"login":"my_login", "password":"my_password"}
url = "http://example.net/login"
r = s.post(url, data=data)

Now your session contains cookies provided by login form. To access cookies of this session simply use

s.cookies

Any further actions like another requests will have this cookie

As your clock.js is in the root, put your code as this to call your javascript in the index.html found in the folders you mentioned.

<SCRIPT LANGUAGE="JavaScript" SRC="../clock.js"></SCRIPT>

This will call the clock.js which you put in the root of your web site.

I had the same error for a different package. My problem was that a dependent project was referencing a different version. I changed them to be the same version and all was good.

Here's some sample code. This worked for me.

<LinearLayout
    android:gravity="center"
    >
    <TextView
        android:layout_gravity="center"
        />
    <Button
        android:layout_gravity="center"
        />
</LinearLayout>

So you're designing the Linear Layout to place all its contents (TextView and Button) in its center, and then the TextView and Button are placed relative to the center of the Linear Layout.

An asynchronous version of extension function:

    public static async Task<WebResponse> GetResponseAsyncNoEx(this WebRequest request)
    {
        try
        {
            return await request.GetResponseAsync();
        }
        catch(WebException ex)
        {
            return ex.Response;
        }
    }

Therefore, I would like to separate the string by the furthest delimiter.

I know this is an old question, but this is a simple requirement for which SUBSTR and INSTR would suffice. REGEXP are still slower and CPU intensive operations than the old subtsr and instr functions.

SQL> WITH DATA AS
  2    ( SELECT 'F/P/O' str FROM dual
  3    )
  4  SELECT SUBSTR(str, 1, Instr(str, '/', -1, 1) -1) part1,
  5         SUBSTR(str, Instr(str, '/', -1, 1) +1) part2
  6  FROM DATA
  7  /

PART1 PART2
----- -----
F/P   O

As you said you want the furthest delimiter, it would mean the first delimiter from the reverse.

You approach was fine, but you were missing the start_position in INSTR. If the start_position is negative, the INSTR function counts back start_position number of characters from the end of string and then searches towards the beginning of string.

Though its late but following solution worked form me.

    let control = this.registerForm.controls['controlName'];
    control.setErrors({backend: {someProp: "Invalid Data"}});
    let message = control.errors['backend'].someProp;

You can find a really good boilerplate made by Henrik Joreteg (ampersandjs) here: https://github.com/HenrikJoreteg/hjs-webpack

Then in your webpack.config.js

var getConfig = require('hjs-webpack')

module.exports = getConfig({
  in: 'src/index.js',
  out: 'public',
  clearBeforeBuild: true,
  https: process.argv.indexOf('--https') !== -1
})

IF YOU NEED TO DYNAMICALLY PASS FRAGMENT ARGUMENTS DO THIS

There are plenty of (mostly repeated or outdated) answers here but none of them handles a very common need: dynamically passing different arguments to the Fragment loaded into a tab.

You can't dynamically pass different arguments to the loaded Fragment by using setSelectedItemId(R.id.second_tab), which ends up calling the static OnNavigationItemSelectedListener. To overcome this limitation I've ended up doing this in my MainActivity that contains the tabs:

fun loadArticleTab(articleId: String) {
    bottomNavigationView.menu.findItem(R.id.tab_article).isChecked = true // use setChecked() in Java
    supportFragmentManager
        .beginTransaction()
        .replace(R.id.main_fragment_container, ArticleFragment.newInstance(articleId))
        .commit()
}

The ArticleFragment.newInstance() method is implemented as usual:

private const val ARG_ARTICLE_ID = "ARG_ARTICLE_ID"

class ArticleFragment : Fragment() {

    companion object {
        /**
         * @return An [ArticleFragment] that shows the article with the given ID.
         */
        fun newInstance(articleId: String): ArticleFragment {
            val args = Bundle()
            args.putString(ARG_ARTICLE_ID, day)
            val fragment = ArticleFragment()
            fragment.arguments = args
            return fragment
        }
    }

}

The login with Facebook button on your site is linking to:

https://www.facebook.com/v2.2/dialog/oauth?client_id=1500708243571026&redirect_uri=http://openstrategynetwork.com/_oauth/facebook&display=popup&scope=email&state=eyJsb2dpblN0eWxlIjoicG9wdXAiLCJjcmVkZW50aWFsVG9rZW4iOiIwSXhEU05XamJjU0VaQWdqcmF6SXdOUWRuRFozXzc0X19lbVhGWUJTZGNYIiwiaXNDb3Jkb3ZhIjpmYWxzZX0=

Notice: redirect_uri=http://openstrategynetwork.com/_oauth/facebook

If you instead change the link to:

redirect_uri=http://openstrategynetwork.com/_oauth/facebook?close

It should work. Or, you can change the Facebook link to http://openstrategynetwork.com/_oauth/facebook

You can also add http://localhost/_oauth/facebook to the valid redirect URIs.

Facebook requires that you whitelist redirect URIs, since otherwise people could login with Facebook for your service, and then send their access token to an attacker's server! And you don't want that to happen ;]

In jQuery, a new element can be created by passing a HTML string to the constructor, as shown below:

var img = $('<img id="dynamic">'); //Equivalent: $(document.createElement('img'))
img.attr('src', responseObject.imgurl);
img.appendTo('#imagediv');

The Swift 3.0 beta official documentation has provided its standard solution for this situation under the title String.UTF16View in section UTF16View Elements Match NSString Characters title

As of Git 2.19 you can simply:

git branch --sort=-committerdate

You can also:

git config branch.sort -committerdate

So whenever you list branches in the current repository, it will be listed sorted by committerdate.

If whenever you list branches, you want them sorted by comitterdate:

git config --global branch.sort -committerdate

Disclaimer: I'm the author of this feature in Git, and I implemented it when I saw this question.

From the documentation

NOTE: On the JVM, if all of the parameters of the primary constructor have default values, the compiler will generate an additional parameterless constructor which will use the default values. This makes it easier to use Kotlin with libraries such as Jackson or JPA that create class instances through parameterless constructors.

#include<stdio.h>
#include<pthread.h>
void* myprint(void *x)
{
 int k = *((int *)x);
 printf("\n Thread created.. value of k [%d]\n",k);
 //k =11;
 pthread_exit((void *)k);

}
int main()
{
 pthread_t th1;
 int x =5;
 int *y;
 pthread_create(&th1,NULL,myprint,(void*)&x);
 pthread_join(th1,(void*)&y);
 printf("\n Exit value is [%d]\n",y);
}  

I use AJAX to do this. You have your partial with your typical twitter modal template html:

<div class="container">
  <!-- Modal -->
  <div class="modal fade" id="LocationNumberModal" role="dialog">
    <div class="modal-dialog">
      <!-- Modal content-->
      <div class="modal-content">
        <div class="modal-header">
          <button type="button" class="close" data-dismiss="modal">
            &times;
          </button>
          <h4 class="modal-title">
            Serial Numbers
          </h4>
        </div>
        <div class="modal-body">
          <span id="test"></span>
          <p>Some text in the modal.</p>
        </div>
        <div class="modal-footer">
          <button type="button" class="btn btn-default" data-dismiss="modal">
            Close
          </button>
        </div>
      </div>
    </div>
  </div>
</div>

Then you have your controller method, I use JSON and have a custom class that rendors the view to a string. I do this so I can perform multiple ajax updates on the screen with one ajax call. Reference here: Example but you can use an PartialViewResult/ActionResult on return if you are just doing the one call. I will show it using JSON..

And the JSON Method in Controller:

public JsonResult LocationNumberModal(string partNumber = "")
{
  //Business Layer/DAL to get information
  return Json(new {
      LocationModal = ViewUtility.RenderRazorViewToString(this.ControllerContext, "LocationNumberModal.cshtml", new SomeModelObject())
    },
    JsonRequestBehavior.AllowGet
  );
}

And then, in the view using your modal: You can package the AJAX in your partial and call @{Html.RenderPartial... Or you can have a placeholder with a div:

<div id="LocationNumberModalContainer"></div>

then your ajax:

function LocationNumberModal() {
  var partNumber = "1234";

  var src = '@Url.Action("LocationNumberModal", "Home", new { area = "Part" })'
    + '?partNumber='' + partNumber; 

  $.ajax({
    type: "GET",
    url: src,
    dataType: "json",
    contentType: "application/json; charset=utf-8",
    success: function (data) {
      $("#LocationNumberModalContainer").html(data.LocationModal);
      $('#LocationNumberModal').modal('show');
    }
  });
};

Then the button to your modal:

<button type="button" id="GetLocBtn" class="btn btn-default" onclick="LocationNumberModal()">Get</button>

Using {dplyr}:

library(dplyr)

# percentiles
infert %>% 
  mutate(PCT = ntile(age, 100))

# quartiles
infert %>% 
  mutate(PCT = ntile(age, 4))

# deciles
infert %>% 
  mutate(PCT = ntile(age, 10))

Or, once it's already in SSIS, you could create a derived column (as part of some data flow task) with:

(DT_I8)FLOOR((DT_R8)systemDateTime)

But you'd have to test to doublecheck.

You can essentially do this 2 ways:

The .htaccess route with mod_rewrite

Add a file called .htaccess in your root folder, and add something like this:

RewriteEngine on
RewriteRule ^/?Some-text-goes-here/([0-9]+)$ /picture.php?id=$1

This will tell Apache to enable mod_rewrite for this folder, and if it gets asked a URL matching the regular expression it rewrites it internally to what you want, without the end user seeing it. Easy, but inflexible, so if you need more power:

The PHP route

Put the following in your .htaccess instead: (note the leading slash)

FallbackResource /index.php

This will tell it to run your index.php for all files it cannot normally find in your site. In there you can then for example:

$path = ltrim($_SERVER['REQUEST_URI'], '/');    // Trim leading slash(es)
$elements = explode('/', $path);                // Split path on slashes
if(empty($elements[0])) {                       // No path elements means home
    ShowHomepage();
} else switch(array_shift($elements))             // Pop off first item and switch
{
    case 'Some-text-goes-here':
        ShowPicture($elements); // passes rest of parameters to internal function
        break;
    case 'more':
        ...
    default:
        header('HTTP/1.1 404 Not Found');
        Show404Error();
}

This is how big sites and CMS-systems do it, because it allows far more flexibility in parsing URLs, config and database dependent URLs etc. For sporadic usage the hardcoded rewrite rules in .htaccess will do fine though.

You can also simply use http authentication with Digest (Here some infos if you use Apache httpd, Apache Tomcat, and here an explanation of digest).

With Java, for interesting informations, take a look at :

• Understanding Login Authentication
• HTTP Digest Authentication Request & Response Examples
• HTTP Authentication Woes
• Basic Authentication For JSP Page (it's not digest, but I think it's an interesting source)

In Spring 5

@PostMapping( "some/request/path" )
public void someControllerMethod( @RequestParam MultiValueMap body ) {

    // import org.springframework.util.MultiValueMap;

    String datax = (String) body .getFirst("datax");
}

strconv.Itoa(int(time.Now().Unix()))

I found the following explanation from https://javascript.info/array very helpful:

One of the oldest ways to cycle array items is the for loop over indexes:

let arr = ["Apple", "Orange", "Pear"];

for (let i = 0; i < arr.length; i++) { alert( arr[i] ); } But for arrays there is another form of loop, for..of:

let fruits = ["Apple", "Orange", "Plum"];

// iterates over array elements for (let fruit of fruits) { alert( fruit ); } The for..of doesn’t give access to the number of the current element, just its value, but in most cases that’s enough. And it’s shorter.

Technically, because arrays are objects, it is also possible to use for..in:

let arr = ["Apple", "Orange", "Pear"];

for (let key in arr) { alert( arr[key] ); // Apple, Orange, Pear } But that’s actually a bad idea. There are potential problems with it:

The loop for..in iterates over all properties, not only the numeric ones.

There are so-called “array-like” objects in the browser and in other environments, that look like arrays. That is, they have length and indexes properties, but they may also have other non-numeric properties and methods, which we usually don’t need. The for..in loop will list them though. So if we need to work with array-like objects, then these “extra” properties can become a problem.

The for..in loop is optimized for generic objects, not arrays, and thus is 10-100 times slower. Of course, it’s still very fast. The speedup may only matter in bottlenecks. But still we should be aware of the difference.

Generally, we shouldn’t use for..in for arrays.

1st: Get personal access token. https://github.com/settings/tokens
2nd: Put account & the token. Example is here:

$ git push
Username for 'https://github.com':            # Put your GitHub account name
Password for 'https://{USERNAME}@github.com': # Put your Personal access token

Link on how to create a personal access token: https://help.github.com/en/github/authenticating-to-github/creating-a-personal-access-token-for-the-command-line

If it doesn't have to be an array, you can create a "multidimensional" JS object...

<script type="text/javascript">
var myObj = { 
    fred: { apples: 2, oranges: 4, bananas: 7, melons: 0 }, 
    mary: { apples: 0, oranges: 10, bananas: 0, melons: 0 }, 
    sarah: { apples: 0, oranges: 0, bananas: 0, melons: 5 } 
}

document.write(myObj['fred']['apples']);
</script>

Yes, using System.Reflection:

using System.Reflection;

...

    string prop = "name";
    PropertyInfo pi = myObject.GetType().GetProperty(prop);
    pi.SetValue(myObject, "Bob", null);

Looking at this official google link: Youtube Live encoder settings, bitrates and resolutions they have this table:

                   240p       360p        480p        720p        1080p
Resolution      426 x 240   640 x 360   854x480     1280x720    1920x1080
Video Bitrates                   
Maximum         700 Kbps    1000 Kbps   2000 Kbps   4000 Kbps   6000 Kbps
Recommended     400 Kbps    750 Kbps    1000 Kbps   2500 Kbps   4500 Kbps
Minimum         300 Kbps    400 Kbps    500 Kbps    1500 Kbps   3000 Kbps

It would appear as though this is the case, although the numbers dont sync up to the google table above:

// the bitrates, video width and file names for this clip
      bitrates: [
        { url: "bbb-800.mp4", width: 480, bitrate: 800 }, //360p video
        { url: "bbb-1200.mp4", width: 720, bitrate: 1200 }, //480p video
        { url: "bbb-1600.mp4", width: 1080, bitrate: 1600 } //720p video
      ],

Thank you everyone, for all your precise replys.

Using the svg in a shadow dom, I add the 3 linear gradients I need within the svg, inside a . I place the css fill rule on the web component and the inheritance od fill does the job.

The first one is normal SVG, the second one is inside a shadow dom.

Yet another work around!One of the solutions, which suggested clicking Alt Enter didn't have the Setup JDK for me, but Add ... to classpathworked.

The most simple way in my opinion would be to use the PyCharm IDE and install the 'multirun' plugin. I tried alot of the solutions here but this one worked for me in the end!

vector<string> getseq(char * db_file)

And if you want to print it on main() you should do it in a loop.

int main() {
     vector<string> str_vec = getseq(argv[1]);
     for(vector<string>::iterator it = str_vec.begin(); it != str_vec.end(); it++) {
         cout << *it << endl;
     }
}

You can use this css code to get gutterless grid in bootstrap.

.no-gutter.row,
.no-gutter.container,
.no-gutter.container-fluid{
  margin-left: 0;
  margin-right: 0;
}

.no-gutter>[class^="col-"]{
  padding-left: 0;
  padding-right: 0;
}

Bootstrap 3 removed those color options for badges. However, we can add those styles manually. Here's my solution, and here is the JS Bin:

.badge {
  padding: 1px 9px 2px;
  font-size: 12.025px;
  font-weight: bold;
  white-space: nowrap;
  color: #ffffff;
  background-color: #999999;
  -webkit-border-radius: 9px;
  -moz-border-radius: 9px;
  border-radius: 9px;
}
.badge:hover {
  color: #ffffff;
  text-decoration: none;
  cursor: pointer;
}
.badge-error {
  background-color: #b94a48;
}
.badge-error:hover {
  background-color: #953b39;
}
.badge-warning {
  background-color: #f89406;
}
.badge-warning:hover {
  background-color: #c67605;
}
.badge-success {
  background-color: #468847;
}
.badge-success:hover {
  background-color: #356635;
}
.badge-info {
  background-color: #3a87ad;
}
.badge-info:hover {
  background-color: #2d6987;
}
.badge-inverse {
  background-color: #333333;
}
.badge-inverse:hover {
  background-color: #1a1a1a;
}

Makefile part of the question

This is pretty easy, unless you don't need to generalize try something like the code below (but replace space indentation with tabs near g++)

SRC_DIR := .../src
OBJ_DIR := .../obj
SRC_FILES := $(wildcard $(SRC_DIR)/*.cpp)
OBJ_FILES := $(patsubst $(SRC_DIR)/%.cpp,$(OBJ_DIR)/%.o,$(SRC_FILES))
LDFLAGS := ...
CPPFLAGS := ...
CXXFLAGS := ...

main.exe: $(OBJ_FILES)
   g++ $(LDFLAGS) -o $@ $^

$(OBJ_DIR)/%.o: $(SRC_DIR)/%.cpp
   g++ $(CPPFLAGS) $(CXXFLAGS) -c -o $@ $<

Automatic dependency graph generation

A "must" feature for most make systems. With GCC in can be done in a single pass as a side effect of the compilation by adding -MMD flag to CXXFLAGS and -include $(OBJ_FILES:.o=.d) to the end of the makefile body:

CXXFLAGS += -MMD
-include $(OBJ_FILES:.o=.d)

And as guys mentioned already, always have GNU Make Manual around, it is very helpful.

From the WordPress Codex:

<?php

Yes. Blat or any other self contained SMTP mailer. Blat is a fairly full featured SMTP client that runs from command line

Blat is here

is it too late?

I personally agree with Beatrice Len, I used paramiko maybe is an extra step for windows, but I have an example project git hub, feel free to clone or ask me.

html

<input id="something" onkeyup="key_up(this)" type="text">

script

function key_up(e){
    var enterKey = 13; //Key Code for Enter Key
    if (e.which == enterKey){
        //Do you work here
    }
}

Next time, Please try providing some code.

The above mentioned answers are correct but I am simplifying it for noobs like me.Go to your project's pom file. Add a new property exec.mainClass and give its value as the class which contains your main method. For me it was DriverClass in mainpkg. Change it as per your project.

Having done this navigate to the folder that contains your project's pom.xml and run this on the command prompt mvn exec:java. This should call the main method.

class Program
{
    static void Main(string[] args)
    {
        Timer timer = new Timer(new TimerCallback(TimeCallBack),null,1000,50000);
        Console.Read();
        timer.Dispose();
    }

    public static void TimeCallBack(object o)
    {
      curMinute = DateTime.Now.Minute;
      if (lastMinute < curMinute) {
       // do your once-per-minute code here
       lastMinute = curMinute;
    }
}

The code could resemble something like the one above

Copy multiple directories:

scp -r dir1 dir2 dir3 [email protected]:~/

Given that the XML field is named 'xmlField'...

SELECT 
[xmlField].value('(/person//firstName/node())[1]', 'nvarchar(max)') as FirstName,
[xmlField].value('(/person//lastName/node())[1]', 'nvarchar(max)') as LastName
FROM [myTable]

You can use ReactChildren and ReactChild:

import React, { ReactChildren, ReactChild } from 'react';
 
interface AuxProps {
  children: ReactChild | ReactChildren;
}

const Aux = ({ children }: AuxProps) => (<div>{children}</div>);

export default Aux;

If you need to pass flat arrays of elements:

interface AuxProps {
  children: ReactChild | ReactChild[] | ReactChildren | ReactChildren[];
}

You can probably use timers : http://msdn.microsoft.com/en-us/library/system.timers.timer.aspx

Timers can provide you a precision up to 1 millisecond. Depending on the tick interval an event will be generated. Do your stuff inside the tick event.

Necromancing.

Since you said ALL views, technically, all answers to date are WRONG.
Here is how to get ALL views:

SELECT 
     sch.name AS view_schema 
    ,sysv.name AS view_name 
    ,ISNULL(sysm.definition, syssm.definition) AS view_definition 
    ,create_date 
    ,modify_date 
FROM sys.all_views AS sysv 

INNER JOIN sys.schemas AS sch 
    ON sch.schema_id = sysv.schema_id 

LEFT JOIN sys.sql_modules AS sysm 
    ON sysm.object_id = sysv.object_id 

LEFT JOIN sys.system_sql_modules AS syssm 
    ON syssm.object_id = sysv.object_id 

-- INNER JOIN sys.objects AS syso ON syso.object_id = sysv.object_id 

WHERE (1=1) 
AND (sysv.type = 'V') -- seems unnecessary, but who knows
-- AND sch.name = 'INFORMATION_SCHEMA' 
/*
AND sysv.is_ms_shipped = 0  
AND NOT EXISTS 
(
    SELECT * FROM sys.extended_properties AS syscrap
    WHERE syscrap.major_id = sysv.object_id
    AND syscrap.minor_id = 0 
    AND syscrap.class = 1 
    AND syscrap.name = N'microsoft_database_tools_support' 
)  
*/

ORDER BY 
     view_schema 
    ,view_name 

If there is trouble with the method onActivityResult that is inside the fragment class, and you want to update something that's is also inside the fragment class, use:

@Override
public void onActivityResult(int requestCode, int resultCode, Intent data) {

    if(resultCode == Activity.RESULT_OK)
    {
        // If the user had agreed to enabling Bluetooth,
        // populate the ListView with all the paired devices.
        this.arrayDevice = new ArrayAdapter<String>(this.getContext(), R.layout.device_item);
        for(BluetoothDevice bd : this.btService.btAdapater.getBondedDevices())
        {
            this.arrayDevice.add(bd.getAddress());
            this.btDeviceList.setAdapter(this.arrayDevice);
        }
    }
    super.onActivityResult(requestCode, resultCode, data);
}

Just add the this.variable as shown in the code above. Otherwise the method will be called within the parent activity and the variable will not updated of the current instance.

I tested it also by putting this block of code into the MainActivity, replacing this with the HomeFragment class and having the variables static. I got results as I expected.

So if you want to have the fragment class having its own implementation of onActivityResult, the code example above is the answer.

((AppCompatActivity) getActivity()).getSupportFragmentManager()

You can use ajax upload to preview your selected file.. http://zurb.com/playground/ajax-upload

I had a similar issue, where I had one div holding the image, and one div holding the text. The reason mine wasn't working, was that the div holding the image had display: inline-block while the div holding the text had display: inline.

I changed it to both be display: inline and it worked.

Here's a solution for a basic header section with a logo, title and tagline:

HTML

<div class="site-branding">
  <div class="site-branding-logo">
    <img src="add/Your/URI/Here" alt="what Is The Image About?" />
  </div>
</div>
<div class="site-branding-text">
  <h1 id="site-title">Site Title</h1>
  <h2 id="site-tagline">Site Tagline</h2>
</div>

CSS

div.site-branding { /* Position Logo and Text  */
  display: inline-block;
  vertical-align: middle;
}

div.site-branding-logo { /* Position logo within site-branding */
  display: inline;
  vertical-align: middle;
}

div.site-branding-text { /* Position text within site-branding */
    display: inline;
    width: 350px;
    margin: auto 0;
    vertical-align: middle;
}

div.site-branding-title { /* Position title within text */
    display: inline;
}

div.site-branding-tagline { /* Position tagline within text */
    display: block;
}

You can also do the following;

string json = myJObject.ToString(Newtonsoft.Json.Formatting.None);

Seems to work.

var widthRange = new Array();
widthRange[46] = { sel:46, min:0,  max:52 };
widthRange[66] = { sel:66, min:52, max:70 };
widthRange[90] = { sel:90, min:70, max:94 };

for (var key in widthRange)
{
    document.write(widthRange[key].sel + "<br />");
    document.write(widthRange[key].min + "<br />");
    document.write(widthRange[key].max + "<br />");
}

to avoid the problem with CDROM: sudo nano /etc/apt/sources.list

find your cdrom and comment it with #

save the changes: "cntrl + o", than exit the file: "cntrl + x"

and try to install again

From Pro C# 5.0 and the .NET 4.5 Framework

The ObservableCollection<T> class is very useful in that it has the ability to inform external objects when its contents have changed in some way (as you might guess, working with ReadOnlyObservableCollection<T> is very similar, but read-only in nature). In many ways, working with the ObservableCollection<T> is identical to working with List<T>, given that both of these classes implement the same core interfaces. What makes the ObservableCollection<T> class unique is that this class supports an event named CollectionChanged. This event will fire whenever a new item is inserted, a current item is removed (or relocated), or if the entire collection is modified. Like any event, CollectionChanged is defined in terms of a delegate, which in this case is NotifyCollectionChangedEventHandler. This delegate can call any method that takes an object as the first parameter, and a NotifyCollectionChangedEventArgs as the second. Consider the following Main() method, which populates an observable collection containing Person objects and wires up the CollectionChanged event:

class Program
{
   static void Main(string[] args)
   {
     // Make a collection to observe and add a few Person objects.
     ObservableCollection<Person> people = new ObservableCollection<Person>()
     {
        new Person{ FirstName = "Peter", LastName = "Murphy", Age = 52 },
        new Person{ FirstName = "Kevin", LastName = "Key", Age = 48 },
     };
     // Wire up the CollectionChanged event.
     people.CollectionChanged += people_CollectionChanged;
     // Now add a new item.
     people.Add(new Person("Fred", "Smith", 32));

     // Remove an item.
     people.RemoveAt(0);

     Console.ReadLine();
   }
   static void people_CollectionChanged(object sender, System.Collections.Specialized.NotifyCollectionChangedEventArgs e)
   {
       // What was the action that caused the event?
        Console.WriteLine("Action for this event: {0}", e.Action);

        // They removed something. 
        if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Remove)
        {
            Console.WriteLine("Here are the OLD items:");
            foreach (Person p in e.OldItems)
            {
                Console.WriteLine(p.ToString());
            }
            Console.WriteLine();
        }

        // They added something. 
        if (e.Action == System.Collections.Specialized.NotifyCollectionChangedAction.Add)
        {
            // Now show the NEW items that were inserted.
            Console.WriteLine("Here are the NEW items:");
            foreach (Person p in e.NewItems)
            {
                Console.WriteLine(p.ToString());
            }
        }
   }
}

The incoming NotifyCollectionChangedEventArgs parameter defines two important properties, OldItems and NewItems, which will give you a list of items that were currently in the collection before the event fired, and the new items that were involved in the change. However, you will want to examine these lists only under the correct circumstances. Recall that the CollectionChanged event can fire when items are added, removed, relocated, or reset. To discover which of these actions triggered the event, you can use the Action property of NotifyCollectionChangedEventArgs. The Action property can be tested against any of the following members of the NotifyCollectionChangedAction enumeration:

public enum NotifyCollectionChangedAction
{
Add = 0,
Remove = 1,
Replace = 2,
Move = 3,
Reset = 4,
}

Since Java arrays hold a fixed number of values, you need to create a new array with a length of 5 in this case. A better solution would be to use an ArrayList and simply add strings to the array.

Example:

ArrayList<String> scripts = new ArrayList<String>();
scripts.add("test3");
scripts.add("test4");
scripts.add("test5");

// Then later you can add more Strings to the ArrayList
scripts.add("test1");
scripts.add("test2");

I faced the same problem but When I changed the skin of AVD device to HVGA, it worked.

Yeah, use .match, rather than .search. The result from the .match call will return the actual string that was matched itself, but it can still be used as a boolean value.

var string = "Stackoverflow is the BEST";
var result = string.match(/best/i);
// result == 'BEST';

if (result){
    alert('Matched');
}

Using a regular expression like that is probably the tidiest and most obvious way to do that in JavaScript, but bear in mind it is a regular expression, and thus can contain regex metacharacters. If you want to take the string from elsewhere (eg, user input), or if you want to avoid having to escape a lot of metacharacters, then you're probably best using indexOf like this:

matchString = 'best';
// If the match string is coming from user input you could do
// matchString = userInput.toLowerCase() here.

if (string.toLowerCase().indexOf(matchString) != -1){
    alert('Matched');
}

Sadly, the coverage of this input field in the modern browsers is very low:

http://caniuse.com/#feat=input-number

Therefore, I recommend to expect the fallback and rely on a heavy-programmatically-loaded input[type=text] to do the job, until the field is generally accepted.

So far, only Chrome, Safari and Opera have a neat implementation, but all other browsers are buggy. Some of them, don't even seem to support decimals (like BB10)!

I found a post suggesting a solution for that. It's about to run:

svn resolve --accept working <YourPath>

which will claim the local version files as OK.
You can run it for single file or entire project catalogues.

You mean like

$target.hide('slow')

?

When nginx returns 400(bad request) it will log the reason into error log, at "info" level and take a look into error log when testing.
