Correct me if I'm wrong

  nohup myprocess.out &

nohup catches the hangup signal, which mean it will send a process when terminal closed.

 myprocess.out &

Process can run but will stopped once the terminal is closed.

nohup myprocess.out

Process able to run even terminal closed, but you are able to stop the process by pressing ctrl + z in terminal. Crt +z not working if & is existing.

If you have standart output redirect to "nohup.out" just see who use this file

lsof | grep nohup.out

On my AIX system, I tried

nohup -p  processid>

This worked well. It continued to run my process even after closing terminal windows. We have ksh as default shell so the bg and disown commands didn't work.

when you create a job in nohup it will tell you the process ID !

nohup sh test.sh &

the output will show you the process ID like

25013

you can kill it then :

kill 25013

nohup some_command &> nohup2.out &

and voila.

Older syntax for Bash version < 4:

nohup some_command > nohup2.out 2>&1 &

I ran into this error recently after using Laravel's built-in authentication routing using php artisan make:auth. When you run that command, these new routes are added to your web.php file:

Auth::routes();

Route::get('/home', 'HomeController@index')->name('home');

I must have accidentally deleted these routes. Running php artisan make:auth again restored the routes and solved the problem. I'm running Laravel 5.5.28.

jQuery 1.4 has a new feature for doing this, and it rules. I've forgotten what it's called, but you use it like this:

$("a.directions-link").attr("href", function(i, href) {
  return href + '?q=testing';
});

That loops over all the elements too, so no need for $.each

SELECT DISTINCT (column1), column2
FROM table1
GROUP BY column1

If you want to write bytes then you should open the file in binary mode.

f = open('/tmp/output', 'wb')

As per your question requirement , I would like to suggest that Map will solve your problem very efficient and without any hassle.

In Map you can give the name as key and your original object as value.

  Map<String,Cave> myMap=new HashMap<String,Cave>();

About CharsetFilter mentioned in @kosoant answer ....

There is a build in Filter in tomcat web.xml (located at conf/web.xml). The filter is named setCharacterEncodingFilter and is commented by default. You can uncomment this ( Please remember to uncomment its filter-mapping too )

Also there is no need to set jsp-config in your web.xml (I have test it for Tomcat 7+ )

I got this error after change a loop in my program, let`s see:

for ...
  for ... 
     x_batch.append(one_hot(int_word, vocab_size))
     y_batch.append(one_hot(int_nb, vocab_size, value))
  ...
  ...
  if ...
        x_batch = np.asarray(x_batch)
        y_batch = np.asarray(y_batch)
...

In fact, I was reusing the variable and forgot to reset them inside the external loop, like the comment of John Lyon:

for ...
  x_batch = []
  y_batch = []
  for ... 
     x_batch.append(one_hot(int_word, vocab_size))
     y_batch.append(one_hot(int_nb, vocab_size, value))
  ...
  ...
  if ...
        x_batch = np.asarray(x_batch)
        y_batch = np.asarray(y_batch)
...

Then, check if you are using np.asarray() or something like that.

This happened to me as well on Windows on two local branches I created myself. Once out of the branch, I was not able to checkout

bugfix_#303_multiline_opmerkingen_not_displaying_correctly_in_viewer

nor

bugfix_339_hidden_fields_still_validated

you can see in the screenshot from Git bash below.

When I tried using Git GUI, I wasn't even able to see the branches at all. However when I used Pycharms git tool, I saw this:

So for some reason windows decided to add some indecipherable character to my branch names and that is the reason it didn't work. Renaming the branches in Pycharm did the trick, so guess this would work on other IDEs as well.

To start activity as dialog I defined it like this in AndroidManifest.xml:

<activity android:theme="@android:style/Theme.Dialog" />

Use this property inside your activity tag to avoid that your Dialog appears in the recently used apps list

android:excludeFromRecents="true"

If you want to stop your dialog / activity from being destroyed when the user clicks outside of the dialog:

After setContentView() in your Activity use:

this.setFinishOnTouchOutside(false);

Now when I call startActivity() it displays as a dialog, with the previous activity shown when the user presses the back button.

Note that if you are using ActionBarActivity (or AppCompat theme), you'll need to use @style/Theme.AppCompat.Dialog instead.

Add extra transport to jquery for IE. ( Just add this code in your script at the end )

$.ajaxTransport("+*", function( options, originalOptions, jqXHR ) {

    if(jQuery.browser.msie && window.XDomainRequest) {

        var xdr;

        return {

            send: function( headers, completeCallback ) {

                // Use Microsoft XDR
                xdr = new XDomainRequest();

                xdr.open("get", options.url);

                xdr.onload = function() {

                    if(this.contentType.match(/\/xml/)){

                        var dom = new ActiveXObject("Microsoft.XMLDOM");
                        dom.async = false;
                        dom.loadXML(this.responseText);
                        completeCallback(200, "success", [dom]);

                    }else{

                        completeCallback(200, "success", [this.responseText]);

                    }

                };

                xdr.ontimeout = function(){
                    completeCallback(408, "error", ["The request timed out."]);
                };

                xdr.onerror = function(){
                    completeCallback(404, "error", ["The requested resource could not be found."]);
                };

                xdr.send();
          },
          abort: function() {
              if(xdr)xdr.abort();
          }
        };
      }
    });

This solved my problem with Jquery $.ajax failing for Cross Domain AJAX request.

Cheers.

Httponly cookies' purpose is being inaccessible by script, so you CAN NOT.

More general sorted, where the key keyword defines the sorting method, minus before numerical type indicates descending:

>>> x = Counter({'a':5, 'b':3, 'c':7})
>>> sorted(x.items(), key=lambda k: -k[1])  # Ascending
[('c', 7), ('a', 5), ('b', 3)]

There's no OrderedSet in official library. I make an exhaustive cheatsheet of all the data structure for your reference.

DataStructure = {
    'Collections': {
        'Map': [
            ('dict', 'OrderDict', 'defaultdict'),
            ('chainmap', 'types.MappingProxyType')
        ],
        'Set': [('set', 'frozenset'), {'multiset': 'collection.Counter'}]
    },
    'Sequence': {
        'Basic': ['list', 'tuple', 'iterator']
    },
    'Algorithm': {
        'Priority': ['heapq', 'queue.PriorityQueue'],
        'Queue': ['queue.Queue', 'multiprocessing.Queue'],
        'Stack': ['collection.deque', 'queue.LifeQueue']
        },
    'text_sequence': ['str', 'byte', 'bytearray']
}

Use sprintf.

int sprintf ( char * str, const char * format, ... );

Write formatted data to string Composes a string with the same text that would be printed if format was used on printf, but instead of being printed, the content is stored as a C string in the buffer pointed by str.

The size of the buffer should be large enough to contain the entire resulting string (see snprintf for a safer version).

A terminating null character is automatically appended after the content.

After the format parameter, the function expects at least as many additional arguments as needed for format.

Parameters:

str

Pointer to a buffer where the resulting C-string is stored. The buffer should be large enough to contain the resulting string.

format

C string that contains a format string that follows the same specifications as format in printf (see printf for details).

... (additional arguments)

Depending on the format string, the function may expect a sequence of additional arguments, each containing a value to be used to replace a format specifier in the format string (or a pointer to a storage location, for n). There should be at least as many of these arguments as the number of values specified in the format specifiers. Additional arguments are ignored by the function.

Example:

// Allocates storage
char *hello_world = (char*)malloc(13 * sizeof(char));
// Prints "Hello world!" on hello_world
sprintf(hello_world, "%s %s!", "Hello", "world");

Something I did recently, hope it helps. I have a list of dictionaries and wanted to add a value to some existing documents.

for item in my_list:
    my_collection.update({"_id" : item[key] }, {"$set" : {"New_col_name" :item[value]}})

Available Zoom Levels

Zoom level 0 is the most zoomed out zoom level available and each integer step in zoom level halves the X and Y extents of the view and doubles the linear resolution.

Google Maps was built on a 256x256 pixel tile system where zoom level 0 was a 256x256 pixel image of the whole earth. A 256x256 tile for zoom level 1 enlarges a 128x128 pixel region from zoom level 0.

As correctly stated by bkaid, the available zoom range depends on where you are looking and the kind of map you are using:

• Road maps - seem to go up to zoom level 22 everywhere
• Hybrid and satellite maps - the max available zoom levels depend on location. Here are some examples:
• Remote regions of Antarctica: 13
• Gobi Desert: 17
• Much of the U.S. and Europe: 21
• "Deep zoom" locations: 22-23 (see bkaid's link)

Note that these values are for the Google Static Maps API which seems to give one more zoom level than the Javascript API. It appears that the extra zoom level available for Static Maps is just an upsampled version of the max-resolution image from the Javascript API.

Map Scale at Various Zoom Levels

Google Maps uses a Mercator projection so the scale varies substantially with latitude. A formula for calculating the correct scale based on latitude is:

meters_per_pixel = 156543.03392 * Math.cos(latLng.lat() * Math.PI / 180) / Math.pow(2, zoom)

Formula is from Chris Broadfoot's comment.

What you're looking for are the scales for each zoom level. Use these:

20 : 1128.497220
19 : 2256.994440
18 : 4513.988880
17 : 9027.977761
16 : 18055.955520
15 : 36111.911040
14 : 72223.822090
13 : 144447.644200
12 : 288895.288400
11 : 577790.576700
10 : 1155581.153000
9  : 2311162.307000
8  : 4622324.614000
7  : 9244649.227000
6  : 18489298.450000
5  : 36978596.910000
4  : 73957193.820000
3  : 147914387.600000
2  : 295828775.300000
1  : 591657550.500000

There are two ways to do the redirect. Both apply to either subprocess.Popen or subprocess.call.

1. Set the keyword argument shell = True or executable = /path/to/the/shell and specify the command just as you have it there.

2. Since you're just redirecting the output to a file, set the keyword argument

   stdout = an_open_writeable_file_object
   

   where the object points to the output file.

subprocess.Popen is more general than subprocess.call.

Popen doesn't block, allowing you to interact with the process while it's running, or continue with other things in your Python program. The call to Popen returns a Popen object.

call does block. While it supports all the same arguments as the Popen constructor, so you can still set the process' output, environmental variables, etc., your script waits for the program to complete, and call returns a code representing the process' exit status.

returncode = call(*args, **kwargs) 

is basically the same as calling

returncode = Popen(*args, **kwargs).wait()

call is just a convenience function. It's implementation in CPython is in subprocess.py:

def call(*popenargs, timeout=None, **kwargs):
    """Run command with arguments.  Wait for command to complete or
    timeout, then return the returncode attribute.

    The arguments are the same as for the Popen constructor.  Example:

    retcode = call(["ls", "-l"])
    """
    with Popen(*popenargs, **kwargs) as p:
        try:
            return p.wait(timeout=timeout)
        except:
            p.kill()
            p.wait()
            raise

As you can see, it's a thin wrapper around Popen.

I have just solved the problem. There was something causing problems with a standard Request call, so this is the code I used instead:

vote.each(function(element){                
  element.addEvent('submit', function(e){
    e.stop();
    new Request.JSON({
      url : e.target.action, 
      onRequest : function(){
        spinner.show();
      },
      onComplete : function(){
        spinner.hide();
      },
      onSuccess : function(resp){
        var j = resp;
        if (!j) return false;
        var restaurant = element.getParent('.restaurant');
        restaurant.getElements('.votes')[0].set('html', j.votes + " vote(s)");
        $$('#restaurants .restaurant').pop().set('html', "Total Votes: " + j.totalvotes);
        buildRestaurantGraphs();
      }
    }).send(this);
  });
});

If anyone knows why the standard Request object was giving me problems I would love to know.

There are a few ways of doing that... the simplest is to have the async method also do the follow-on operation. Another popular approach is to pass in a callback, i.e.

void RunFooAsync(..., Action<bool> callback) {
     // do some stuff
     bool result = ...

     if(callback != null) callback(result);
}

Another approach would be to raise an event (with the result in the event-args data) when the async operation is complete.

Also, if you are using the TPL, you can use ContinueWith:

Task<bool> outerTask = ...;
outerTask.ContinueWith(task =>
{
    bool result = task.Result;
    // do something with that
});

You should not need to add this back in. This was removed purposefully. The documentation has changed somewhat and the CSS class that is necessary ("nav-stacked") is only mentioned under the pills component, but should work for tabs as well.

This tutorial shows how to use the Bootstrap 3 setup properly to do vertical tabs:
tutsme-webdesign.info/bootstrap-3-toggable-tabs-and-pills

This method modifies both the back color (to dark red) and the text (to white) if a specific string ("TextToMatch") occurs in one of the columns:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.Cells[8].Text.Equals("TextToMatch"))
    {
        e.Row.BackColor = System.Drawing.Color.DarkRed;
        e.Row.ForeColor = System.Drawing.Color.White;
    }
}

Or another way to write it:

protected void GridView1_RowDataBound(object sender, GridViewRowEventArgs e)
{
    if (e.Row.Cells[8].Text.Equals("TextToMatch"))
    {
        e.Row.Attributes.CssStyle.Value = "background-color: DarkRed; color: White";
    }
}

Here is how one can do it via the global request helper function.

{{ request()->segment(1) }}

Note: request() returns the object of the Request class.

There must be a user in the AllowUsers section, in the config file /etc/ssh/ssh_config, in the remote machine. You might have to restart sshd after editing the config file.

And then you can copy for example the file "test.txt" from a remote host to the local host

scp [email protected]:test.txt /local/dir

@cool_cs you can user ~ symbol ~/Users/djorge/Desktop if it's your home dir.

In UNIX, absolute paths must start with '/'.

The ID of the two repos are both localSnap; that's probably not what you want and it might confuse Maven.

If that's not it: There might be more repository elements in your POM. Search the output of mvn help:effective-pom for repository to make sure the number and place of them is what you expect.

This function should do the trick if you want to specify a particular sheet. I took the solution from user6432984 and modified it to not throw any errors. I am using Excel 2016 so it may not work for older versions:

Function findLastRow(ByVal inputSheet As Worksheet) As Integer
    findLastRow = inputSheet.cellS(inputSheet.Rows.Count, 1).End(xlUp).Row
End Function

This is the code to run if you are already working in the sheet you want to find the last row of:

Dim lastRow as Integer
lastRow = cellS(Rows.Count, 1).End(xlUp).Row

format = '%Y-%m-%d %H:%M %p'

The format is using %H instead of %I. Since %H is the "24-hour" format, it's likely just discarding the %p information. It works just fine if you change the %H to %I.

map() doesn't return a list, it returns a map object.

You need to call list(map) if you want it to be a list again.

Even better,

from itertools import imap
payIntList = list(imap(int, payList))

Won't take up a bunch of memory creating an intermediate object, it will just pass the ints out as it creates them.

Also, you can do if choice.lower() == 'n': so you don't have to do it twice.

Python supports +=: you can do payIntList[i] += 1000 and numElements += 1 if you want.

If you really want to be tricky:

from itertools import count
for numElements in count(1):
    payList.append(raw_input("Enter the pay amount: "))
    if raw_input("Do you wish to continue(y/n)?").lower() == 'n':
         break

and / or

for payInt in payIntList:
    payInt += 1000
    print payInt

Also, four spaces is the standard indent amount in Python.

try the following code :

In your controller :

 function myCtrl ($scope) {
      $scope.units = [
         {'id': 10, 'label': 'test1'},
         {'id': 27, 'label': 'test2'},
         {'id': 39, 'label': 'test3'},
      ];

   $scope.data= $scope.units[0]; // Set by default the value "test1"
 };

In your page :

 <select ng-model="data" ng-options="opt as opt.label for opt in units ">
                </select>

the simple way I believe is to import it then export it, using the certificate manager in Windows Management Console.

This may be a common problem for new users of Matplotlib to draw vertical and horizontal lines. In order to understand this problem, you should be aware that different coordinate systems exist in Matplotlib.

The method axhline and axvline are used to draw lines at the axes coordinate. In this coordinate system, coordinate for the bottom left point is (0,0), while the coordinate for the top right point is (1,1), regardless of the data range of your plot. Both the parameter xmin and xmax are in the range [0,1].

On the other hand, method hlines and vlines are used to draw lines at the data coordinate. The range for xmin and xmax are the in the range of data limit of x axis.

Let's take a concrete example,

import matplotlib.pyplot as plt
import numpy as np

x = np.linspace(0, 5, 100)
y = np.sin(x)

fig, ax = plt.subplots()

ax.plot(x, y)
ax.axhline(y=0.5, xmin=0.0, xmax=1.0, color='r')
ax.hlines(y=0.6, xmin=0.0, xmax=1.0, color='b')

plt.show()

It will produce the following plot:

The value for xmin and xmax are the same for the axhline and hlines method. But the length of produced line is different.

eldNew <- eld[-14,]

See ?"[" for a start ...

For ‘[’-indexing only: ‘i’, ‘j’, ‘...’ can be logical vectors, indicating elements/slices to select. Such vectors are recycled if necessary to match the corresponding extent. ‘i’, ‘j’, ‘...’ can also be negative integers, indicating elements/slices to leave out of the selection.

(emphasis added)

edit: looking around I notice How to delete the first row of a dataframe in R? , which has the answer ... seems like the title should have popped to your attention if you were looking for answers on SO?

Also http://rwiki.sciviews.org/doku.php?id=tips:data-frames:remove_rows_data_frame

Yes, there is a bool data type (which inherits from int and has only two values: True and False).

But also Python has the boolean-able concept for every object, which is used when function bool([x]) is called.

See more: object.nonzero and boolean-value-of-objects-in-python.

By running the above command you can see what are all the jobs running.

kill -9 <PID Number>

Enter the PID (process identification number), so this will terminate/kill the instance.

You have to just add the below line in your toolbar layout:

I got similar error (org.aspectj.apache.bcel.classfile.ClassFormatException: Invalid byte tag in constant pool: 15) while using aspectj 1.8.13. Solution was to align all compilation into jdk 8 and being careful not to put aspectj library's (1.6.13 for instance) other versions to buildpath/classpath.

I had the same problem, and the registry answers here didn't work.

I had a browser control in new version of my program that worked fine on XP, failed in Windows 7 (64 bit). The old version worked on both XP and Windows 7.

The webpage displayed in the browser uses some strange plugin for showing old SVG maps (I think its a Java applet).

Turns out the problem is related to DEP protection in Windows 7.

Old versions of dotnet 2 didn't set the DEP required flag in the exe, but from dotnet 2, SP 1 onwards it did (yep, the compiling behaviour and hence runtime behaviour of exe changed depending on which machine you compiled on, nice ...).

It is documented on a MSDN blog NXCOMPAT and the C# compiler. To quote : This will undoubtedly surprise a few developers...download a framework service pack, recompile, run your app, and you're now getting IP_ON_HEAP exceptions.

Adding the following to the post build in Visual Studio, turns DEP off for the exe, and everything works as expected:

all "$(DevEnvDir)..\tools\vsvars32.bat"
editbin.exe /NXCOMPAT:NO "$(TargetPath)"

• Editbin documentation
• Dumpbin /headers will display the DEP setting on a exe.

The solution of prijin worked perfectly for me. It is just fair to mention that two additional permissions are needed:

<uses-permission android:name="android.permission.BLUETOOTH"/>
<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>

When these are added, enabling and disabling works flawless with the default bluetooth adapter.

In jQuery 1.4:

Here's a slightly more flexible approach using the match method. With this, you can extract more than one string:

s = "<ants> <pants>"
matchdata = s.match(/<([^>]*)> <([^>]*)>/)

# Use 'captures' to get an array of the captures
matchdata.captures   # ["ants","pants"]

# Or use raw indices
matchdata[0]   # whole regex match: "<ants> <pants>"
matchdata[1]   # first capture: "ants"
matchdata[2]   # second capture: "pants"

Worked for me in 30 seconds, short and sweet:

1. In IIS Manager (run inetmgr)
2. Go to ApplicationPool -> Advanced Settings
3. Set ApplicationPoolIdentity to NetworkService
4. Go to the file, right click properties, go to security, click edit, click add, enter Network Service (with space, then click 'check names'), and give full control (or just whatever permissions you need)

        graph.annotate('{:.0f}'.format(p.get_height()), (p.get_x()+0.3, p.get_height()),
                    ha='center', va='bottom',

There is one more way without creating a object also. Check the reference. Thanks for @cristian. Below I add the steps which mentioned in the above reference. For me I don't like to create a object for that and access. So I tried to access the getResources() without creating a object. I found this post. So I thought to add it as a answer.

Follow the steps to access getResources() in a non activity class without passing a context through the object.

• Create a subclass of Application, for instance public class App extends Application {. Refer the code next to the steps.
• Set the android:name attribute of your <application> tag in the AndroidManifest.xml to point to your new class, e.g. android:name=".App"
• In the onCreate() method of your app instance, save your context (e.g. this) to a static field named app and create a static method that returns this field, e.g. getContext().
• Now you can use: App.getContext() whenever you want to get a context, and then we can use App.getContext().getResources() to get values from the resources.

This is how it should look:

public class App extends Application{

    private static Context mContext;

    @Override
    public void onCreate() {
        super.onCreate();
        mContext = this;
    }

    public static Context getContext(){
        return mContext;
    }
}

I am not really sure why, but as soon as I comment out the following method it works:

connectionDidFinishDownloading:destinationURL:

Furthermore, I don't think you need the methods from the NSUrlConnectionDownloadDelegate protocol, only those from NSURLConnectionDataDelegate, unless you want some download information.

Coming back to the original problem - java.lang.ClassNotFoundException: com.sun.jersey.spi.container.servlet.ServletContainer

As rightly said above, in JAX 2.x version, the ServletContainer class has been moved to the package - org.glassfish.jersey.servlet.ServletContainer. The related jar is jersey-container-servlet-core.jar which comes bundled within the jaxrs-ri-2.2.1.zip

JAX RS can be worked out without mvn by manually copying all jars contained within zip file jaxrs-ri-2.2.1.zip (i have used this version, would work with any 2.x version) to WEB-INF/lib folder. Copying libs to right folder makes them available at runtime.

This is required if you are using eclipse to build and deploy your project.

I was having the same problem. This worked for me:

.center {
    margin: 0 auto; 
    width: 400px;
    **display:block**
 }

i think you are doing every thing fine just remove ";" from the last of java_home variable. every thing will work fine.

I have found a way if you know startIndex and endIndex of the elements one need to remove from ArrayList

Let al be the original ArrayList and startIndex,endIndex be start and end index to be removed from the array respectively:

al.subList(startIndex, endIndex + 1).clear();

WHen I run into this problem with it not getting latest and version mismatches I first do a "Get Specific Version" set it to changeset and put in 1. This will then remove all the files from your local workspace (for that project, folder, file, etc) and it will also have TFS update so that it knows you now have NO VERSION DOWNLOADED. You can then do a "Get Latest" and viola, you will actually have the latest

If you don't want to edit the bootstrap CSS or all of the above doesn't help you at all (like in my case), there's an easy fix to get the video running in a modal on Firefox.

You just need to remove the "fade" class from the modal and as it opens the "in" class, too:

$('#myModal').on('shown.bs.modal', function () {
    $('#myModal').removeClass('in');
});

Try this:

Intent intent = new Intent(Intent.ACTION_MAIN);
          intent.addCategory(Intent.CATEGORY_HOME);
          intent.setFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);//***Change Here***
          startActivity(intent);
          finish();
          System.exit(0);

HttpClient webClient = new HttpClient();
Uri uri = new Uri("your url");
HttpResponseMessage response = await webClient.GetAsync(uri)
var jsonString = await response.Content.ReadAsStringAsync();
var objData = JsonConvert.DeserializeObject<List<CategoryModel>>(jsonString);

You can create a data.sql file in your src/main/resources folder and it will be automatically executed on startup. In this file you can add some insert statements, eg.:

INSERT INTO users (username, firstname, lastname) VALUES
  ('lala', 'lala', 'lala'),
  ('lolo', 'lolo', 'lolo');

Similarly, you can create a schema.sql file (or schema-h2.sql) as well to create your schema:

CREATE TABLE task (
  id          INTEGER PRIMARY KEY,
  description VARCHAR(64) NOT NULL,
  completed   BIT NOT NULL);

Though normally you shouldn't have to do this since Spring boot already configures Hibernate to create your schema based on your entities for an in memory database. If you really want to use schema.sql you'll have to disable this feature by adding this to your application.properties:

spring.jpa.hibernate.ddl-auto=none

More information can be found at the documentation about Database initialization.

If you're using Spring boot 2, database initialization only works for embedded databases (H2, HSQLDB, ...). If you want to use it for other databases as well, you need to change the spring.datasource.initialization-mode property:

spring.datasource.initialization-mode=always

If you're using multiple database vendors, you can name your file data-h2.sql or data-mysql.sql depending on which database platform you want to use.

To make that work, you'll have to configure the spring.datasource.platform property though:

spring.datasource.platform=h2

Dashboard -> [your app] -> [View Details] -> Settings -> Basic

Solution 1: Remove the explicit type definition

Since getPerson already returns a Person with a name, we can use the inferred type.

function getPerson(){
  let person = {name:"John"};
  return person;
}

let person = getPerson();

If we were to define person: Person we would lose a piece of information. We know getPerson returns an object with a non-optional property called name, but describing it as Person would bring the optionality back.

Solution 2: Use a more precise definition

type Require<T, K extends keyof T> = T & {
  [P in K]-?: T[P]
};

function getPerson() {
  let person = {name:"John"};
  return person;
}

let person: Require<Person, 'name'> = getPerson();
let name1:string = person.name;

Solution 3: Redesign your interface

A shape in which all properties are optional is called a weak type and usually is an indicator of bad design. If we were to make name a required property, your problem goes away.

interface Person {
  name:string,
  age?:string,
  gender?:string,
  occupation?:string,
}

You can just "call" your model with an array of the correct shape:

model(np.array([[6.7, 3.3, 5.7, 2.5]]))

Full example:

from sklearn.datasets import load_iris
from tensorflow.keras.layers import Dense
from tensorflow.keras.models import Sequential
import numpy as np

X, y = load_iris(return_X_y=True)

model = Sequential([
    Dense(16, activation='relu'),
    Dense(32, activation='relu'),
    Dense(1)])

model.compile(loss='mean_absolute_error', optimizer='adam')

history = model.fit(X, y, epochs=10, verbose=0)

print(model(np.array([[6.7, 3.3, 5.7, 2.5]])))

<tf.Tensor: shape=(1, 1), dtype=float64, numpy=array([[1.92517677]])>

I know, I know, but...

public static bool TryGetQueryString<T>(string key, out T queryString)

If you have named tuples you can do this:

results = [t.age for t in mylist if t.person_id == 10]

Otherwise use indexes:

results = [t[1] for t in mylist if t[0] == 10]

Or use tuple unpacking as per Nate's answer. Note that you don't have to give a meaningful name to every item you unpack. You can do (person_id, age, _, _, _, _) to unpack a six item tuple.

How to get the last N rows of a pandas DataFrame?

If you are slicing by position, __getitem__ (i.e., slicing with[]) works well, and is the most succinct solution I've found for this problem.

pd.__version__
# '0.24.2'

df = pd.DataFrame({'A': list('aaabbbbc'), 'B': np.arange(1, 9)})
df

   A  B
0  a  1
1  a  2
2  a  3
3  b  4
4  b  5
5  b  6
6  b  7
7  c  8

df[-3:]

   A  B
5  b  6
6  b  7
7  c  8

This is the same as calling df.iloc[-3:], for instance (iloc internally delegates to __getitem__).

As an aside, if you want to find the last N rows for each group, use groupby and GroupBy.tail:

df.groupby('A').tail(2)

   A  B
1  a  2
2  a  3
5  b  6
6  b  7
7  c  8

In jQuery there is $.isPlainObject() method for that:

Description: Check to see if an object is a plain object (created using "{}" or "new Object").

Multi joins in SQL work by progressively creating derived tables one after the other. See this link explaining the process:

Update from Python 3.4

Use the pathlib module.

from pathlib import Path
path = Path("/here/your/path/file.txt")
print(path.parent)

Old answer

Try this:

import os.path
print os.path.abspath(os.path.join(yourpath, os.pardir))

where yourpath is the path you want the parent for.

This is an old, but still topical question. Just test with the is_dir() or file_exists() function for the presence of the . or .. file in the directory under test. Each directory must contain these files:

is_dir("path_to_directory/.");    

You can install pywin32 wheel packages from PYPI with PIP by pointing to this package: https://pypi.python.org/pypi/pypiwin32 No need to worry about first downloading the package, just use pip:

pip install pypiwin32

Currently I think this is "the easiest" way to get in working :) Hope this helps.

It's a new feature called Modules or "semantic import". There's more info in the WWDC 2013 videos for Session 205 and 404. It's kind of a better implementation of the pre-compiled headers. You can use modules with any of the system frameworks in iOS 7 and Mavericks. Modules are a packaging together of the framework executable and its headers and are touted as being safer and more efficient than #import.

One of the big advantages of using @import is that you don't need to add the framework in the project settings, it's done automatically. That means that you can skip the step where you click the plus button and search for the framework (golden toolbox), then move it to the "Frameworks" group. It will save many developers from the cryptic "Linker error" messages.

You don't actually need to use the @import keyword. If you opt-in to using modules, all #import and #include directives are mapped to use @import automatically. That means that you don't have to change your source code (or the source code of libraries that you download from elsewhere). Supposedly using modules improves the build performance too, especially if you haven't been using PCHs well or if your project has many small source files.

Modules are pre-built for most Apple frameworks (UIKit, MapKit, GameKit, etc). You can use them with frameworks you create yourself: they are created automatically if you create a Swift framework in Xcode, and you can manually create a ".modulemap" file yourself for any Apple or 3rd-party library.

You can use code-completion to see the list of available frameworks:

Modules are enabled by default in new projects in Xcode 5. To enable them in an older project, go into your project build settings, search for "Modules" and set "Enable Modules" to "YES". The "Link Frameworks" should be "YES" too:

You have to be using Xcode 5 and the iOS 7 or Mavericks SDK, but you can still release for older OSs (say iOS 4.3 or whatever). Modules don't change how your code is built or any of the source code.

From the WWDC slides:

• Imports complete semantic description of a framework
• Doesn't need to parse the headers
• Better way to import a framework’s interface
• Loads binary representation
• More flexible than precompiled headers
• Immune to effects of local macro definitions (e.g. #define readonly 0x01)
• Enabled for new projects by default

To explicitly use modules:

Replace #import <Cocoa/Cocoa.h> with @import Cocoa;

You can also import just one header with this notation:

@import iAd.ADBannerView;

The submodules autocomplete for you in Xcode.

Yes, as said by Thanakron Tandavas,

Recursion is good when you are solving a problem that can be solved by divide and conquer technique.

For example: Towers of Hanoi

1. N rings in increasing size
2. 3 poles
3. Rings start stacked on pole 1. Goal is to move rings so that they are stacked on pole 3 ...But
   • Can only move one ring at a time.
   • Can’t put larger ring on top of smaller.
4. Iterative solution is “powerful yet ugly”; recursive solution is “elegant”.

Simply delete that column using: del df['column_name']

As others have stated, there is no portable function that works on all systems. You can partially circumvent this with simple ifdef:

#include <stdio.h>

#ifdef _WIN32
#include <string.h>
#define strcasecmp _stricmp
#else // assuming POSIX or BSD compliant system
#include <strings.h>
#endif

int main() {
    printf("%d", strcasecmp("teSt", "TEst"));
}

Tip: Only use first() if:

• You consider zero items emitted to be an error condition (eg. completing before emitting) AND if there’s a greater than 0% chance of error you handling it gracefully
• OR You know 100% that the source observable will emit 1+ items (so can never throw).

If there are zero emissions and you are not explicitly handling it (with catchError) then that error will get propagated up, possibly cause an unexpected problem somewhere else and can be quite tricky to track down - especially if it's coming from an end user.

You're safer off using take(1) for the most part provided that:

• You're OK with take(1) not emitting anything if the source completes without an emission.
• You don't need to use an inline predicate (eg. first(x => x > 10) )

Note: You can use a predicate with take(1) like this: .pipe( filter(x => x > 10), take(1) ). There is no error with this if nothing is ever greater than 10.

What about single()

If you want to be even stricter, and disallow two emissions you can use single() which errors if there are zero or 2+ emissions. Again you'd need to handle errors in that case.

Tip: Single can occasionally be useful if you want to ensure your observable chain isn't doing extra work like calling an http service twice and emitting two observables. Adding single to the end of the pipe will let you know if you made such a mistake. I'm using it in a 'task runner' where you pass in a task observable that should only emit one value, so I pass the response through single(), catchError() to guarantee good behavior.

Why not always use first() instead of take(1) ?

aka. How can first potentially cause more errors?

If you have an observable that takes something from a service and then pipes it through first() you should be fine most of the time. But if someone comes along to disable the service for whatever reason - and changes it to emit of(null) or NEVER then any downstream first() operators would start throwing errors.

Now I realize that might be exactly what you want - hence why this is just a tip. The operator first appealed to me because it sounded slightly less 'clumsy' than take(1) but you need to be careful about handling errors if there's ever a chance of the source not emitting. Will entirely depend on what you're doing though.

If you have a default value (constant):

Consider also .pipe(defaultIfEmpty(42), first()) if you have a default value that should be used if nothing is emitted. This would of course not raise an error because first would always receive a value.

Note that defaultIfEmpty is only triggered if the stream is empty, not if the value of what is emitted is null.

function setWidth(width) {
  var canvas = document.getElementById("myCanvas");  
  canvas.width = width;
}

Little bit late to the party but had some problems with getting something useful out from a ReadableStream produced from a Odata $batch request using the Sharepoint Framework.

Had similar issues as OP, but the solution in my case was to use a different conversion method than .json(). In my case .text() worked like a charm. Some fiddling was however necessary to get some useful JSON from the textfile.

There is no need to use Babel at this moment (JS has become very powerful) when you can simply use the default JavaScript module exports. Check full tutorial

Message.js

module.exports = 'Hello world';

app.js

var msg = require('./Messages.js');

console.log(msg); // Hello World

The "Legacy Build System" solution didn't work for me. What worked it was:

1. Clean project and remove "DerivedData".
2. Remove input files not found from project (only references, don't delete files).
3. Build (=> will generate errors related to missing files).
4. Add files again to project.
5. Build (=> should SUCCEED).

Cross-browser @media (width) and @media (height) values 

const vw = Math.max(document.documentElement.clientWidth || 0, window.innerWidth || 0)
const vh = Math.max(document.documentElement.clientHeight || 0, window.innerHeight || 0)

window.innerWidth and window.innerHeight

• gets CSS viewport @media (width) and @media (height) which include scrollbars
• initial-scale and zoom variations may cause mobile values to wrongly scale down to what PPK calls the visual viewport and be smaller than the @media values
• zoom may cause values to be 1px off due to native rounding
• undefined in IE8-

document.documentElement.clientWidth and .clientHeight

• equals CSS viewport width minus scrollbar width
• matches @media (width) and @media (height) when there is no scrollbar
• same as jQuery(window).width() which jQuery calls the browser viewport
• available cross-browser
• inaccurate if doctype is missing

Resources

• Live outputs for various dimensions
• verge uses cross-browser viewport techniques
• actual uses matchMedia to obtain precise dimensions in any unit

TryGetValue is slightly faster, because FindEntry will only be called once.

How much faster? It depends on the dataset at hand. When you call the Contains method, Dictionary does an internal search to find its index. If it returns true, you need another index search to get the actual value. When you use TryGetValue, it searches only once for the index and if found, it assigns the value to your variable.

FYI: It's not actually catching an error.

It's calling:

public bool TryGetValue(TKey key, out TValue value)
{
    int index = this.FindEntry(key);
    if (index >= 0)
    {
        value = this.entries[index].value;
        return true;
    }
    value = default(TValue);
    return false;
}

ContainsKey is this:

public bool ContainsKey(TKey key)
{
    return (this.FindEntry(key) >= 0);
}

When dealing with mocking lists and iterating them, I always use something like:

@Spy
private List<Object> parts = new ArrayList<>();

you can define a route in web.php

Route::get('/clear/route', 'ConfigController@clearRoute');

and make ConfigController.php like this

   class ConfigController extends Controller
{
    public function clearRoute()
    {
        \Artisan::call('route:clear');
    }
}

and go to that route on server example http://your-domain/clear/route

Installing the Chrome extension IE Tab did the job for me.

It has the ability to auto-detect URLs so whenever I browse to our SharePoint it emulates Internet Explorer. Finally I can open Office documents directly from Chrome.

You can install IETab for FireFox too.

For Python 3 and beyond: str.zfill() is still the most readable option

But it is a good idea to look into the new and powerful str.format(), what if you want to pad something that is not 0?

    # if we want to pad 22 with zeros in front, to be 5 digits in length:
    str_output = '{:0>5}'.format(22)
    print(str_output)
    # >>> 00022
    # {:0>5} meaning: ":0" means: pad with 0, ">" means move 22 to right most, "5" means the total length is 5

    # another example for comparision
    str_output = '{:#<4}'.format(11)
    print(str_output)
    # >>> 11##

    # to put it in a less hard-coded format:
    int_inputArg = 22
    int_desiredLength = 5
    str_output = '{str_0:0>{str_1}}'.format(str_0=int_inputArg, str_1=int_desiredLength)
    print(str_output)
    # >>> 00022

You can use the code below. It selects the pre-existing value in the field and overwrites it with the new value.

driver.findElement(By.xpath("*enter your xpath here*")).sendKeys(Keys.chord(Keys.CONTROL, "a"),*enter the new value here*);

I'm using angular 1.6.4 and answer provided by subhaze didn't work for me. I modified it a bit and then it worked - you have to use value returned by $sce.trustAsResourceUrl. Full code:

var url = "http://public-api.wordpress.com/rest/v1/sites/wtmpeachtest.wordpress.com/posts"
url = $sce.trustAsResourceUrl(url);

$http.jsonp(url, {jsonpCallbackParam: 'callback'})
    .then(function(data){
        console.log(data.found);
    });

With SQL Server 2012 (11.x) and later and Azure SQL Database, you can also have "fetch_row_count_expression", you can also have ORDER BY clause along with this.

USE AdventureWorks2012;  
GO  
-- Specifying variables for OFFSET and FETCH values    
DECLARE @skip int = 0  , @take int = 8;  
SELECT DepartmentID, Name, GroupName  
FROM HumanResources.Department  
ORDER BY DepartmentID ASC   
    OFFSET @skip ROWS   
    FETCH NEXT @take ROWS ONLY; 

https://docs.microsoft.com/en-us/sql/t-sql/queries/select-order-by-clause-transact-sql?view=sql-server-ver15

Note OFFSET Specifies the number of rows to skip before it starts to return rows from the query expression. It is NOT the starting row number. So, it has to be 0 to include first record.

What is the difference between c++ and visaul c++?

Visual C++ is an IDE. There's also C++Builder from Embarcadero. (Used to be Borland.) There are also a few other C++ IDE's.

I know that c++ has the portability and all so if you know c++ how is it related to visual c++?

C++ is as portable as the libraries that you use in your C++ application. VC++ has some specialized libraries to use with Windows, so if you use those libraries in your C++ application, you're stuck with Windows. But a simple "Hello, World" application that just uses the console as output can be compiled on Windows, Linux, VMS, AS/400, Smartphones, FreeBSD, MS-DOS, CP80 and almost any other system for which you can find a C++ compiler. Injteresting fact: at http://nethack.org/ you can download the C sourcecode for an almost antique game, where you have to walk through a bunch of mazes, kick some monsters around, find treasures and steal some valuable amulet and bring that amulet back out. (It's also a game where you can encounter your characters from previous, failed attempts to get that amulet. :-) The sourcecode of NetHack is a fine example of how portable C (C++) code can be.

Is visual c++ mostly for online apps?

No. But it can be used for online apps. Actually, C# is used more often for server-side web applications while C++ (VC++) is used for all kinds of (server) components that your application will be depending upon.

Would visual basic be better for desktop applications?

Or Embarcadero Delphi. Delphi and Basic are languages that are easier to learn than C++ and both have very good IDE's to develop GUI applications with. Unfortunately, Visual Basic is now running on .NET only, while there are still many developers who need to create WIN32 applications. Those developers often have to choose between Delphi or C++ or else convince management to move to .NET development.

Please follow below step to do some processing after Application Context get loaded i.e application is ready to serve.

1. Create below annotation i.e

   @Retention(RetentionPolicy.RUNTIME) @Target(value= {ElementType.METHOD, ElementType.TYPE}) public @interface AfterApplicationReady {}

2.Create Below Class which is a listener which get call on application ready state.

    @Component
    public class PostApplicationReadyListener implements ApplicationListener<ApplicationReadyEvent> {

    public static final Logger LOGGER = LoggerFactory.getLogger(PostApplicationReadyListener.class);
    public static final String MODULE = PostApplicationReadyListener.class.getSimpleName();

    @Override
    public void onApplicationEvent(ApplicationReadyEvent event) {
        try {
            ApplicationContext context = event.getApplicationContext();
            String[] beans = context.getBeanNamesForAnnotation(AfterAppStarted.class);

            LOGGER.info("bean found with AfterAppStarted annotation are : {}", Arrays.toString(beans));

            for (String beanName : beans) {
                Object bean = context.getBean(beanName);
                Class<?> targetClass = AopUtils.getTargetClass(bean);
                Method[] methods = targetClass.getMethods();
                for (Method method : methods) {
                    if (method.isAnnotationPresent(AfterAppStartedComplete.class)) {

                        LOGGER.info("Method:[{} of Bean:{}] found with AfterAppStartedComplete Annotation.", method.getName(), beanName);

                        Method currentMethod = bean.getClass().getMethod(method.getName(), method.getParameterTypes());

                        LOGGER.info("Going to invoke method:{} of bean:{}", method.getName(), beanName);

                        currentMethod.invoke(bean);

                        LOGGER.info("Invocation compeleted method:{} of bean:{}", method.getName(), beanName);
                    }
                }
            }
        } catch (Exception e) {
            LOGGER.warn("Exception occured : ", e);
        }
    }
}

Finally when you start your Spring application just before log stating application started your listener will be called.

You may wrap it in a bash script or git alias:

cd /X/Y && git pull && cd -

.aar is a standard zip archive, the same one used in .jar. Just change the extension and, assuming it's not corrupt or anything, it should be fine.

If you needed to, you could extract it to your filesystem and then repackage it as a jar.

1) Rename it to .jar
2) Extract: jar xf filename.jar
3) Repackage: jar cf output.jar input-file(s)

@media (max-width: 767px) {
    footer .text-right, 
    footer .text-left {
        text-align: center;
    } 
}

I updated @loddn's answer, making two changes

• max-width of xs screens in bootstrap is 767px (768px is the start of sm screens)
• (this one is a matter of preference) I used footer instead of col-* so that if the column widths change, the CSS doesn't need to be updated.

Maybe you can use a for loop that goes through the String content and extract characters by characters using the charAt method.

Combined with an ArrayList<String> for example you can get your array of individual characters.

The right solution is to Specialize std::less for your class/Struct.

• Basically maps in cpp are implemented as Binary Search Trees.

1. BSTs compare elements of nodes to determine the organization of the tree.
2. Nodes who's element compares less than that of the parent node are placed on the left of the parent and nodes whose elements compare greater than the parent nodes element are placed on the right. i.e.

For each node, node.left.key < node.key < node.right.key

Every node in the BST contains Elements and in case of maps its KEY and a value, And keys are supposed to be ordered. More About Map implementation : The Map data Type.

In case of cpp maps , keys are the elements of the nodes and values does not take part in the organization of the tree its just a supplementary data .

So It means keys should be compatible with std::less or operator< so that they can be organized. Please check map parameters.

Else if you are using user defined data type as keys then need to give meaning full comparison semantics for that data type.

Solution : Specialize std::less:

The third parameter in map template is optional and it is std::less which will delegate to operator< ,

So create a new std::less for your user defined data type. Now this new std::less will be picked by std::map by default.

namespace std
{
    template<> struct  less<MyClass>
    {
        bool operator() (const MyClass& lhs, const MyClass& rhs) const
        {
            return lhs.anyMemen < rhs.age;
        }
    };

}

Note: You need to create specialized std::less for every user defined data type(if you want to use that data type as key for cpp maps).

Bad Solution: Overloading operator< for your user defined data type. This solution will also work but its very bad as operator < will be overloaded universally for your data type/class. which is undesirable in client scenarios.

the big problem with this method is the extra markup. (the span tag)

Thanks to Gruff Bunny and Louis' comments, I found the source of the issue.

As I use Backbone.js too, I loaded a special build of Lodash compatible with Backbone and Underscore that disables some features. In this example:

var clone = _.clone(data, true);

data[1].values.d = 'x';

• with the Normal build: _.isEqual(data, clone) === false
• with the Underscore build: _.isEqual(data, clone) === true

I just replaced the Underscore build with the Normal build in my Backbone application and the application is still working. So I can now use the Lodash .clone with the expected behaviour.

Edit 2018: the Underscore build doesn't seem to exist anymore. If you are reading this in 2018, you could be interested by this documentation (Backbone and Lodash).

In NodeJS, we have Buffers available, and string conversion with them is really easy. Better, it's easy to convert a Uint8Array to a Buffer. Try this code, it's worked for me in Node for basically any conversion involving Uint8Arrays:

let str = Buffer.from(uint8arr.buffer).toString();

We're just extracting the ArrayBuffer from the Uint8Array and then converting that to a proper NodeJS Buffer. Then we convert the Buffer to a string (you can throw in a hex or base64 encoding if you want).

If we want to convert back to a Uint8Array from a string, then we'd do this:

let uint8arr = new Uint8Array(Buffer.from(str));

Be aware that if you declared an encoding like base64 when converting to a string, then you'd have to use Buffer.from(str, "base64") if you used base64, or whatever other encoding you used.

This will not work in the browser without a module! NodeJS Buffers just don't exist in the browser, so this method won't work unless you add Buffer functionality to the browser. That's actually pretty easy to do though, just use a module like this, which is both small and fast!

Similar problem - same error message. I got the same message when trying to clone something from bitbucket with ssh. The problem was in my ssh configuration configured in the mercurial.ini: I used the wrong bitbucket username. After I corrected the user name things worked.

Try this, this will hide by clicking outside.

$('body').on('click', function (e) {
    $('[data-toggle="popover"]').each(function () {
    //the 'is' for buttons that trigger popups
    //the 'has' for icons within a button that triggers a popup
    if (!$(this).is(e.target) && $(this).has(e.target).length === 0 && $('.popover').has(e.target).length === 0) {
    $(this).popover('hide');
    }
    });
});

Here's a solution that takes a very different approach: package up all the modules into a JSON object and require modules by reading and executing the file content without additional requests.

https://github.com/STRd6/require/blob/master/main.coffee.md

STRd6/require depends on having a JSON package available at runtime. The require function is generated for that package. The package contains all the files your app could require. No further http requests are made because the package bundles all dependencies. This is as close as one can get to the Node.js style require on the client.

The structure of the package is as follows:

entryPoint: "main"
distribution:
  main: 
    content: "alert(\"It worked!\")"
  ...
dependencies:
  <name>: <a package>

Unlike Node a package doesn't know it's external name. It is up to the pacakge including the dependency to name it. This provides complete encapsulation.

Given all that setup here's a function that loads a file from within a package:

loadModule = (pkg, path) ->
  unless (file = pkg.distribution[path])
    throw "Could not find file at #{path} in #{pkg.name}" 

  program = file.content
  dirname = path.split(fileSeparator)[0...-1].join(fileSeparator)

  module =
    path: dirname
    exports: {}

  context =
    require: generateRequireFn(pkg, module)        
    global: global
    module: module
    exports: module.exports
    PACKAGE: pkg
    __filename: path
    __dirname: dirname

  args = Object.keys(context)
  values = args.map (name) -> context[name]

  Function(args..., program).apply(module, values)

  return module

This external context provides some variable that modules have access to.

A require function is exposed to modules so they may require other modules.

Additional properties such as a reference to the global object and some metadata are also exposed.

Finally we execute the program within the module and given context.

This answer will be most helpful to those who wish to have a synchronous node.js style require statement in the browser and are not interested in remote script loading solutions.

If you're working with actual files (as opposed to some sort of string data), how about the following?

$files | % { "$($_.BaseName -replace '_[^_]+$','')$($_.Extension)" }

(or use _.+$ if you want to cut everything from the first underscore.)

You could compare String representations so:

array1.toString() == array2.toString()
array1.toString() !== array3.toString()

but that would also make

array4 = ['1',2,3,4,5]

equal to array1 if that matters to you

It looks like this issue has to do with the difference between the Content-Type and Accept headers. In HTTP, Content-Type is used in request and response payloads to convey the media type of the current payload. Accept is used in request payloads to say what media types the server may use in the response payload.

So, having a Content-Type in a request without a body (like your GET request) has no meaning. When you do a POST request, you are sending a message body, so the Content-Type does matter.

If a server is not able to process the Content-Type of the request, it will return a 415 HTTP error. (If a server is not able to satisfy any of the media types in the request Accept header, it will return a 406 error.)

In OData v3, the media type "application/json" is interpreted to mean the new JSON format ("JSON light"). If the server does not support reading JSON light, it will throw a 415 error when it sees that the incoming request is JSON light. In your payload, your request body is verbose JSON, not JSON light, so the server should be able to process your request. It just doesn't because it sees the JSON light content type.

You could fix this in one of two ways:

1. Make the Content-Type "application/json;odata=verbose" in your POST request, or

2. Include the DataServiceVersion header in the request and set it be less than v3. For example:

   DataServiceVersion: 2.0;
   

(Option 2 assumes that you aren't using any v3 features in your request payload.)

Linux (and indeed Unix) gives you a third option.

Option 1 - processes

Create a standalone executable which handles some part (or all parts) of your application, and invoke it separately for each process, e.g. the program runs copies of itself to delegate tasks to.

Option 2 - threads

Create a standalone executable which starts up with a single thread and create additional threads to do some tasks

Option 3 - fork

Only available under Linux/Unix, this is a bit different. A forked process really is its own process with its own address space - there is nothing that the child can do (normally) to affect its parent's or siblings address space (unlike a thread) - so you get added robustness.

However, the memory pages are not copied, they are copy-on-write, so less memory is usually used than you might imagine.

Consider a web server program which consists of two steps:

1. Read configuration and runtime data
2. Serve page requests

If you used threads, step 1 would be done once, and step 2 done in multiple threads. If you used "traditional" processes, steps 1 and 2 would need to be repeated for each process, and the memory to store the configuration and runtime data duplicated. If you used fork(), then you can do step 1 once, and then fork(), leaving the runtime data and configuration in memory, untouched, not copied.

So there are really three choices.

It turns out that there is a way to do this, although I'm not sure I've found the 'proper' way since this required hours of reading source code from multiple projects. In other words, this might be a lot of dumb work (but it works).

First, there is no way to get at the server.xml in the embedded Tomcat, either to augment it or replace it. This must be done programmatically.

Second, the 'require_https' setting doesn't help since you can't set cert info that way. It does set up forwarding from http to https, but it doesn't give you a way to make https work so the forwarding isnt helpful. However, use it with the stuff below, which does make https work.

To begin, you need to provide an EmbeddedServletContainerFactory as explained in the Embedded Servlet Container Support docs. The docs are for Java but the Groovy would look pretty much the same. Note that I haven't been able to get it to recognize the @Value annotation used in their example but its not needed. For groovy, simply put this in a new .groovy file and include that file on the command line when you launch spring boot.

Now, the instructions say that you can customize the TomcatEmbeddedServletContainerFactory class that you created in that code so that you can alter web.xml behavior, and this is true, but for our purposes its important to know that you can also use it to tailor server.xml behavior. Indeed, reading the source for the class and comparing it with the Embedded Tomcat docs, you see that this is the only place to do that. The interesting function is TomcatEmbeddedServletContainerFactory.addConnectorCustomizers(), which may not look like much from the Javadocs but actually gives you the Embedded Tomcat object to customize yourself. Simply pass your own implementation of TomcatConnectorCustomizer and set the things you want on the given Connector in the void customize(Connector con) function. Now, there are about a billion things you can do with the Connector and I couldn't find useful docs for it but the createConnector() function in this this guys personal Spring-embedded-Tomcat project is a very practical guide. My implementation ended up looking like this:

package com.deepdownstudios.server

import org.springframework.boot.context.embedded.tomcat.TomcatConnectorCustomizer
import org.springframework.boot.context.embedded.EmbeddedServletContainerFactory
import org.springframework.boot.context.embedded.tomcat.TomcatEmbeddedServletContainerFactory
import org.apache.catalina.connector.Connector;
import org.apache.coyote.http11.Http11NioProtocol;
import org.springframework.boot.*
import org.springframework.stereotype.*

@Configuration
class MyConfiguration {

@Bean
public EmbeddedServletContainerFactory servletContainer() {
final int port = 8443;
final String keystoreFile = "/path/to/keystore"
final String keystorePass = "keystore-password"
final String keystoreType = "pkcs12"
final String keystoreProvider = "SunJSSE"
final String keystoreAlias = "tomcat"

TomcatEmbeddedServletContainerFactory factory = 
        new TomcatEmbeddedServletContainerFactory(this.port);
factory.addConnectorCustomizers( new TomcatConnectorCustomizer() {
    void    customize(Connector con) {
        Http11NioProtocol proto = (Http11NioProtocol) con.getProtocolHandler();
            proto.setSSLEnabled(true);
        con.setScheme("https");
        con.setSecure(true);
        proto.setKeystoreFile(keystoreFile);
        proto.setKeystorePass(keystorePass);
        proto.setKeystoreType(keystoreType);
        proto.setProperty("keystoreProvider", keystoreProvider);
        proto.setKeyAlias(keystoreAlias);
    }
});
return factory;
}
}

The Autowiring will pick up this implementation an run with it. Once I fixed my busted keystore file (make sure you call keytool with -storetype pkcs12, not -storepass pkcs12 as reported elsewhere), this worked. Also, it would be far better to provide the parameters (port, password, etc) as configuration settings for testing and such... I'm sure its possible if you can get the @Value annotation to work with Groovy.

Mongoose 4.4.0 now supports bulk insert

Mongoose 4.4.0 introduces --true-- bulk insert with the model method .insertMany(). It is way faster than looping on .create() or providing it with an array.

Usage:

var rawDocuments = [/* ... */];

Book.insertMany(rawDocuments)
    .then(function(mongooseDocuments) {
         /* ... */
    })
    .catch(function(err) {
        /* Error handling */
    });

Or

Book.insertMany(rawDocuments, function (err, mongooseDocuments) { /* Your callback function... */ });

You can track it on:

• https://github.com/Automattic/mongoose/issues/723
• https://github.com/Automattic/mongoose/blob/1887e72694829b62f4e3547283783cebbe66b46b/lib/model.js#L1774

If you are using an external style sheet, the code could look something like this:

@font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
.junebug { font-family: Junebug; font-size: 4.2em; }

And should be saved in a separate .css file (eg styles.css). If your .css file is in a location separate from the page code, the actual font file should have the same path as the .css file, NOT the .html or .php web page file. Then the web page needs something like:

<link rel="stylesheet" href="css/styles.css">

in the <head> section of your html page. In this example, the font file should be located in the css folder along with the stylesheet. After this, simply add the class="junebug" inside any tag in your html to use Junebug font in that element.

If you're putting the css in the actual web page, add the style tag in the head of the html like:

<style>
    @font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
</style>

And the actual element style can either be included in the above <style> and called per element by class or id, or you can just declare the style inline with the element. By element I mean <div>, <p>, <h1> or any other element within the html that needs to use the Junebug font. With both of these options, the font file (Junebug.ttf) should be located in the same path as the html page. Of these two options, the best practice would look like:

<style>
    @font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
    .junebug { font-family: Junebug; font-size: 4.2em; }
</style>

and

<h1 class="junebug">This is Junebug</h1>

And the least acceptable way would be:

<style>
    @font-face { font-family: Junebug; src: url('Junebug.ttf'); } 
</style>

and

<h1 style="font-family: Junebug;">This is Junebug</h1>

The reason it's not good to use inline styles is best practice dictates that styles should be kept all in one place so editing is practical. This is also the main reason that I recommend using the very first option of using external style sheets. I hope this helps.

Error happens in your function declarations,look the following sentence!You need a semicolon!

If you are logged into your Kibana, you can click on the Management tab and that will show your Kibana version. Alternatively, you can click on the small tube-like icon and that will show the version number.

Another scenario is when you cast a null object into a value type. For example, the code below:

object o = null;
DateTime d = (DateTime)o;

It will throw a NullReferenceException on the cast. It seems quite obvious in the above sample, but this can happen in more "late-binding" intricate scenarios where the null object has been returned from some code you don't own, and the cast is for example generated by some automatic system.

One example of this is this simple ASP.NET binding fragment with the Calendar control:

<asp:Calendar runat="server" SelectedDate="<%#Bind("Something")%>" />

Here, SelectedDate is in fact a property - of DateTime type - of the Calendar Web Control type, and the binding could perfectly return something null. The implicit ASP.NET Generator will create a piece of code that will be equivalent to the cast code above. And this will raise a NullReferenceException that is quite difficult to spot, because it lies in ASP.NET generated code which compiles fine...

See if your script is running GPU in Task manager. If not, suspect your CUDA version is right one for the tensorflow version you are using, as the other answers suggested already.

Additionally, a proper CUDA DNN library for the CUDA version is required to run GPU with tensorflow. Download/extract it from here and put the DLL (e.g., cudnn64_7.dll) into CUDA bin folder (e.g., C:\Program Files\NVIDIA GPU Computing Toolkit\CUDA\v10.1\bin).

Here you will find a better solution OLTP vs. OLAP

• OLTP (On-line Transaction Processing) is involved in the operation of a particular system. OLTP is characterized by a large number of short on-line transactions (INSERT, UPDATE, DELETE). The main emphasis for OLTP systems is put on very fast query processing, maintaining data integrity in multi-access environments and an effectiveness measured by number of transactions per second. In OLTP database there is detailed and current data, and schema used to store transactional databases is the entity model (usually 3NF). It involves Queries accessing individual record like Update your Email in Company database.

• OLAP (On-line Analytical Processing) deals with Historical Data or Archival Data. OLAP is characterized by relatively low volume of transactions. Queries are often very complex and involve aggregations. For OLAP systems a response time is an effectiveness measure. OLAP applications are widely used by Data Mining techniques. In OLAP database there is aggregated, historical data, stored in multi-dimensional schemas (usually star schema). Sometime query need to access large amount of data in Management records like what was the profit of your company in last year.

Installing psqlODBC on 64bit Windows

Though you can install 32 bit ODBC drivers on Win X64 as usual, you can't configure 32-bit DSNs via ordinary control panel or ODBC datasource administrator.

How to configure 32 bit ODBC drivers on Win x64

Configure ODBC DSN from %SystemRoot%\syswow64\odbcad32.exe

1. Start > Run
2. Enter: %SystemRoot%\syswow64\odbcad32.exe
3. Hit return.
4. Open up ODBC and select under the System DSN tab.
5. Select PostgreSQL Unicode

You may have to play with it and try different scenarios, think outside-the-box, remember this is open source.

Another way...

# translate long options to short
for arg
do
    delim=""
    case "$arg" in
       --help) args="${args}-h ";;
       --verbose) args="${args}-v ";;
       --config) args="${args}-c ";;
       # pass through anything else
       *) [[ "${arg:0:1}" == "-" ]] || delim="\""
           args="${args}${delim}${arg}${delim} ";;
    esac
done
# reset the translated args
eval set -- $args
# now we can process with getopt
while getopts ":hvc:" opt; do
    case $opt in
        h)  usage ;;
        v)  VERBOSE=true ;;
        c)  source $OPTARG ;;
        \?) usage ;;
        :)
        echo "option -$OPTARG requires an argument"
        usage
        ;;
    esac
done

If you do gridview.bind() at:

if(!IsPostBack)

{

//your gridview bind code here...

}

Then you can use DataTable dt = Gridview1.DataSource as DataTable; in function to retrieve datatable.

But I bind the datatable to gridview when i click button, and recording to Microsoft document:

HTTP is a stateless protocol. This means that a Web server treats each HTTP request for a page as an independent request. The server retains no knowledge of variable values that were used during previous requests.

If you have same condition, then i will recommend you to use Session to persist the value.

Session["oldData"]=Gridview1.DataSource;

After that you can recall the value when the page postback again.

DataTable dt=(DataTable)Session["oldData"];

https://www.c-sharpcorner.com/UploadFile/225740/introduction-of-session-in-Asp-Net/

In some cases, it might be a bad idea to first add the column to the DataGridView and then hide it.

I for example have a class that has an NHibernate proxy for an Image property for company logos. If I accessed that property (e.g. by calling its ToString method to show that in a DataGridView), it would download the image from the SQL server. If I had a list of Company objects and used that as the dataSource of the DataGridView like that, then (I suspect) it would download ALL the logos BEFORE I could hide the column.

To prevent this, I used the custom attribute

 [System.ComponentModel.Browsable(false)]

on the image property, so that the DataGridView ignores the property (doesn't create the column and doesn't call the ToString methods).

 public class Company
 {
     ...
     [System.ComponentModel.Browsable(false)]
     virtual public MyImageClass Logo { get; set;}

One of the answers in the question referred to by @Z.Bagley gave me the answer. I had to import Renderer2 from @angular/core into my component. Then:

const element = this.renderer.selectRootElement('#input1');

// setTimeout(() => element.focus, 0);
setTimeout(() => element.focus(), 0);

Thank you @MrBlaise for the solution!

Neither has anything specific to keyboard or mobile, other than the fact that for years ARM has had a pretty substantial advantage in terms of power consumption, which made it attractive for all sorts of battery operated devices.

As far as the actual differences: ARM has more registers, supported predication for most instructions long before Intel added it, and has long incorporated all sorts of techniques (call them "tricks", if you prefer) to save power almost everywhere it could.

There's also a considerable difference in how the two encode instructions. Intel uses a fairly complex variable-length encoding in which an instruction can occupy anywhere from 1 up to 15 byte. This allows programs to be quite small, but makes instruction decoding relatively difficult (as in: decoding instructions fast in parallel is more like a complete nightmare).

ARM has two different instruction encoding modes: ARM and THUMB. In ARM mode, you get access to all instructions, and the encoding is extremely simple and fast to decode. Unfortunately, ARM mode code tends to be fairly large, so it's fairly common for a program to occupy around twice as much memory as Intel code would. Thumb mode attempts to mitigate that. It still uses quite a regular instruction encoding, but reduces most instructions from 32 bits to 16 bits, such as by reducing the number of registers, eliminating predication from most instructions, and reducing the range of branches. At least in my experience, this still doesn't usually give quite as dense of coding as x86 code can get, but it's fairly close, and decoding is still fairly simple and straightforward. Lower code density means you generally need at least a little more memory and (generally more seriously) a larger cache to get equivalent performance.

At one time Intel put a lot more emphasis on speed than power consumption. They started emphasizing power consumption primarily on the context of laptops. For laptops their typical power goal was on the order of 6 watts for a fairly small laptop. More recently (much more recently) they've started to target mobile devices (phones, tablets, etc.) For this market, they're looking at a couple of watts or so at most. They seem to be doing pretty well at that, though their approach has been substantially different from ARM's, emphasizing fabrication technology where ARM has mostly emphasized micro-architecture (not surprising, considering that ARM sells designs, and leaves fabrication to others).

Depending on the situation, a CPU's energy consumption is often more important than its power consumption though. At least as I'm using the terms, power consumption refers to power usage on a (more or less) instantaneous basis. Energy consumption, however, normalizes for speed, so if (for example) CPU A consumes 1 watt for 2 seconds to do a job, and CPU B consumes 2 watts for 1 second to do the same job, both CPUs consume the same total amount of energy (two watt seconds) to do that job--but with CPU B, you get results twice as fast.

ARM processors tend to do very well in terms of power consumption. So if you need something that needs a processor's "presence" almost constantly, but isn't really doing much work, they can work out pretty well. For example, if you're doing video conferencing, you gather a few milliseconds of data, compress it, send it, receive data from others, decompress it, play it back, and repeat. Even a really fast processor can't spend much time sleeping, so for tasks like this, ARM does really well.

Intel's processors (especially their Atom processors, which are actually intended for low power applications) are extremely competitive in terms of energy consumption. While they're running close to their full speed, they will consume more power than most ARM processors--but they also finish work quickly, so they can go back to sleep sooner. As a result, they can combine good battery life with good performance.

So, when comparing the two, you have to be careful about what you measure, to be sure that it reflects what you honestly care about. ARM does very well at power consumption, but depending on the situation you may easily care more about energy consumption than instantaneous power consumption.

Here's another technique for creating divs with jQuery.

ELEMENT CLONING

Say you have an existing div in your page that you want to clone using jQuery (e.g. to duplicate an input a number of times in a form). You would do so as follows.

$('#clone_button').click(function() {_x000D_
  $('#clone_wrapper div:first')_x000D_
  .clone()_x000D_
  .append('clone')_x000D_
  .appendTo($('#clone_wrapper'));_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<div id="clone_wrapper">_x000D_
  <div>_x000D_
    Div_x000D_
  </div>_x000D_
</div>_x000D_
_x000D_
<button id="clone_button">Clone me!</button>

<video style="min-width: 100%; min-height: 100%; " id="vid" width="auto" height="auto" controls autoplay="true" loop="loop" preload="auto" muted="muted">
<source src="video/sample.mp4" type="video/mp4">
<source src="video/sample.ogg" type="video/ogg">
</video>
<script> 
$(document).ready(function(){
document.getElementById('vid').play(); });
</script> 

First set Storage Engine as InnoDB

then the relation view option enable in structure menu

Actually what u did is also not wrong your declaration is right . With your declaration JVM will create a ArrayList of integer arrays i.e each entry in arraylist correspond to an integer array hence your add function should pass a integer array as a parameter.

For Ex:

list.add(new Integer[3]);

In this way first entry of ArrayList is an integer array which can hold at max 3 values.

<LinearLayout 
    android:layout_width="wrap_content"
    android:layout_height="wrap_content" >

    <RatingBar

        android:numStars="5"
        android:stepSize="0.5"
        style="?android:attr/ratingBarStyleSmall"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />
</LinearLayout>

I disable my Instant Run by:

Menu Preference ? Build ? Instant Run "Enable Instant Run to hot swap code"

I guess it is the Instant Run that makes the build slow and creates a large size pidXXX.hprof file which causes the AndroidStudio gc overhead limit exceeded.

(My device SDK is 19.)

closures are beautiful! they solve a lot of problems that come with anonymous functions, and make really elegant code possible (at least as long as we talk about php).

javascript programmers use closures all the time, sometimes even without knowing it, because bound variables aren't explicitly defined - that's what "use" is for in php.

there are better real-world examples than the above one. lets say you have to sort an multidimensional array by a sub-value, but the key changes.

<?php
    function generateComparisonFunctionForKey($key) {
        return function ($left, $right) use ($key) {
            if ($left[$key] == $right[$key])
                return 0;
            else
                return ($left[$key] < $right[$key]) ? -1 : 1;
        };
    }

    $myArray = array(
        array('name' => 'Alex', 'age' => 70),
        array('name' => 'Enrico', 'age' => 25)
    );

    $sortByName = generateComparisonFunctionForKey('name');
    $sortByAge  = generateComparisonFunctionForKey('age');

    usort($myArray, $sortByName);

    usort($myArray, $sortByAge);
?>

warning: untested code (i don't have php5.3 installed atm), but it should look like something like that.

there's one downside: a lot of php developers may be a bit helpless if you confront them with closures.

to understand the nice-ty of closures more, i'll give you another example - this time in javascript. one of the problems is the scoping and the browser inherent asynchronity. especially, if it comes to window.setTimeout(); (or -interval). so, you pass a function to setTimeout, but you can't really give any parameters, because providing parameters executes the code!

function getFunctionTextInASecond(value) {
    return function () {
        document.getElementsByName('body')[0].innerHTML = value; // "value" is the bound variable!
    }
}

var textToDisplay = prompt('text to show in a second', 'foo bar');

// this returns a function that sets the bodys innerHTML to the prompted value
var myFunction = getFunctionTextInASecond(textToDisplay);

window.setTimeout(myFunction, 1000);

myFunction returns a function with a kind-of predefined parameter!

to be honest, i like php a lot more since 5.3 and anonymous functions/closures. namespaces may be more important, but they're a lot less sexy.

If you're looking to capture everything up to "abc":

/^(.*?)abc/

Explanation:

( ) capture the expression inside the parentheses for access using $1, $2, etc.

^ match start of line

.* match anything, ? non-greedily (match the minimum number of characters required) - [1]

[1] The reason why this is needed is that otherwise, in the following string:

whatever whatever something abc something abc

by default, regexes are greedy, meaning it will match as much as possible. Therefore /^.*abc/ would match "whatever whatever something abc something ". Adding the non-greedy quantifier ? makes the regex only match "whatever whatever something ".

<=> Spaceship Operator

Added in PHP 7

The spaceship operator <=> is the latest comparison operator added in PHP 7. It is a non-associative binary operator with the same precedence as equality operators (==, !=, ===, !==). This operator allows for simpler three-way comparison between left-hand and right-hand operands.

The operator results in an integer expression of:

• 0 when both operands are equal
• Less than 0 when the left-hand operand is less than the right-hand operand
• Greater than 0 when the left-hand operand is greater than the right-hand operand

e.g.

1 <=> 1; // 0
1 <=> 2; // -1
2 <=> 1; // 1

A good practical application of using this operator would be in comparison type callbacks that are expected to return a zero, negative, or positive integer based on a three-way comparison between two values. The comparison function passed to usort is one such example.

Before PHP 7 you would write...

$arr = [4,2,1,3];

usort($arr, function ($a, $b) {
    if ($a < $b) {
        return -1;
    } elseif ($a > $b) {
        return 1;
    } else {
        return 0;
    }
});

Since PHP 7 you can write...

$arr = [4,2,1,3];

usort($arr, function ($a, $b) {
    return $a <=> $b;
});

If you want to get the ASCII value of a character, or just convert it into an int, you need to cast from a char to an int.

What's casting? Casting is when we explicitly convert from one primitve data type, or a class, to another. Here's a brief example.

public class char_to_int
{
  public static void main(String args[])
  {
       char myChar = 'a';
       int  i = (int) myChar; // cast from a char to an int
       System.out.println ("ASCII value - " + i);
  }

In this example, we have a character ('a'), and we cast it to an integer. Printing this integer out will give us the ASCII value of 'a'.

You could use 'vi' and then the following command:

:16224,16482w!/tmp/some-file

Alternatively:

cat file | head -n 16482 | tail -n 258

EDIT:- Just to add explanation, you use head -n 16482 to display first 16482 lines then use tail -n 258 to get last 258 lines out of the first output.

Give this a try

<style type="text/css">

form {width:400px;}

#text1 {float:right;}

#text2 {float:left;}

</style>

then

<form id="form1" name="form1" method="post" action="">


 <label id="text1">Company Name<br />
   <input type="text" name="textfield2" id="textfield2" />
 </label>

 <label id="text2">Contact Name<br />
   <input type="text" name="textfield" id="textfield" />
 </label>


</form>

Works for me in the latest versions of Firefox, Safari, Chrome, Opera. Not 100% sure about IE though as im on a Mac, but I cant see why it wouldn't :)

CPU Virtualization is enabled by default on all MacBooks with compatible CPUs (i7 is compatible). You can try to reset PRAM if you think it was disabled somehow, but I doubt it.

I think the issue might be in the old version of OS. If your MacBook is i7, then you better upgrade OS to something newer.

Servlet is server side technology which is used to create dynamic web page in web application. Actually servlet is an api which consist of group of classes and interfaces, which has some functionality. When we use Servlet API we can use predefined functionality of servlet classes and interfaces.

Lifecycle of Servlet:

Web container maintains the lifecycle of servlet instance.

1 . Servlet class loaded

2 . Servlet instance created

3 . init() method is invoked

4 . service() method invoked

5 . destroy() method invoked

When request raise by client(browser) then web-container checks whether the servlet is running or not if yes then it invoke the service() method and give the response to browser..

When servlet is not running then web-container follow the following steps..

1. classloader load the servlet class

2. Instantiates the servlet

3. Initializes the servlet

4.invoke the service() method

after serving the request web-container wait for specific time, in this time if request comes then it call only service() method otherwise it call destroy() method..

Try to check for existence:

IF NOT EXISTS (SELECT * FROM dbo.Employee WHERE ID = @SomeID)

    INSERT INTO dbo.Employee(Col1, ..., ColN)
    VALUES(Val1, .., ValN)

ELSE

    UPDATE dbo.Employee
    SET Col1 = Val1, Col2 = Val2, ...., ColN = ValN
    WHERE ID = @SomeID

You could easily wrap this into a stored procedure and just call that stored procedure from the outside (e.g. from a programming language like C# or whatever you're using).

Update: either you can just write this entire statement in one long string (doable - but not really very useful) - or you can wrap it into a stored procedure:

CREATE PROCEDURE dbo.InsertOrUpdateEmployee
       @ID INT,
       @Name VARCHAR(50),
       @ItemName VARCHAR(50),  
       @ItemCatName VARCHAR(50),
       @ItemQty DECIMAL(15,2)
AS BEGIN
    IF NOT EXISTS (SELECT * FROM dbo.Table1 WHERE ID = @ID)
       INSERT INTO dbo.Table1(ID, Name, ItemName, ItemCatName, ItemQty)
       VALUES(@ID, @Name, @ItemName, @ItemCatName, @ItemQty)
    ELSE
       UPDATE dbo.Table1
       SET Name = @Name,
           ItemName = @ItemName,
           ItemCatName = @ItemCatName,
           ItemQty = @ItemQty
       WHERE ID = @ID
END

and then just call that stored procedure from your ADO.NET code

Make the list a character vector (not a vector of names)

rm(list = c('temp1','temp2'))

rm(temp1, temp2)

By using pg_restore command you can restore postgres database

First open terminal type

sudo su postgres

Create new database

createdb [database name] -O [owner]

createdb test_db [-O openerp]

pg_restore -d [Database Name] [path of dump file]

pg_restore -d test_db /home/sagar/Download/sample_dbump

Wait for completion of database restoring.

Remember that dump file should have read, write, execute access, so for that you can apply chmod command

TL&DR: When you typically get data from a server, it is sent in bytes. The rationale is that these bytes will need to be 'decoded' by the recipient, who should know how to use the data. You should decode the binary upon arrival to not get 'b' (bytes) but instead a string.

Use case:

import requests    
def get_data_from_url(url):
        response = requests.get(url_to_visit)
        response_data_split_by_line = response.content.decode('utf-8').splitlines()
        return response_data_split_by_line

In this example, I decode the content that I received into UTF-8. For my purposes, I then split it by line, so I can loop through each line with a for loop.

Try this:

var date = new Date();
var hour = date.getHours();
var min = date.getMinutes();

Ran to the same issue, Assuming your using anaconda3 and your using a venv with >= python=3.6:

python -m pip install keras
sudo python -m pip install --user tensorflow

Laravel provides a method called keyBy which allows to set keys by given key in model.

$collection = $collection->keyBy('id');

will return the collection but with keys being the values of id attribute from any model.

Then you can say:

$desired_food = $foods->get(21); // Grab the food with an ID of 21

and it will grab the correct item without the mess of using a filter function.

Have you tried:

Regarding vectors and the hash/array concept from other languages:

1. Vectors are the atoms of R. Eg, rpois(1e4,5) (5 random numbers), numeric(55) (length-55 zero vector over doubles), and character(12) (12 empty strings), are all "basic".

2. Either lists or vectors can have names.

   > n = numeric(10)
   > n
    [1] 0 0 0 0 0 0 0 0 0 0
   > names(n)
   NULL
   > names(n) = LETTERS[1:10]
   > n
   A B C D E F G H I J 
   0 0 0 0 0 0 0 0 0 0
   

3. Vectors require everything to be the same data type. Watch this:

   > i = integer(5)
   > v = c(n,i)
   > v
   A B C D E F G H I J           
   0 0 0 0 0 0 0 0 0 0 0 0 0 0 0 
   > class(v)
   [1] "numeric"
   > i = complex(5)
   > v = c(n,i)
   > class(v)
   [1] "complex"
   > v
      A    B    C    D    E    F    G    H    I    J                          
   0+0i 0+0i 0+0i 0+0i 0+0i 0+0i 0+0i 0+0i 0+0i 0+0i 0+0i 0+0i 0+0i 0+0i 0+0i
   

4. Lists can contain varying data types, as seen in other answers and the OP's question itself.

I've seen languages (ruby, javascript) in which "arrays" may contain variable datatypes, but for example in C++ "arrays" must be all the same datatype. I believe this is a speed/efficiency thing: if you have a numeric(1e6) you know its size and the location of every element a priori; if the thing might contain "Flying Purple People Eaters" in some unknown slice, then you have to actually parse stuff to know basic facts about it.

Certain standard R operations also make more sense when the type is guaranteed. For example cumsum(1:9) makes sense whereas cumsum(list(1,2,3,4,5,'a',6,7,8,9)) does not, without the type being guaranteed to be double.

As to your second question:

Lists can be returned from functions even though you never passed in a List when you called the function

Functions return different data types than they're input all the time. plot returns a plot even though it doesn't take a plot as an input. Arg returns a numeric even though it accepted a complex. Etc.

(And as for strsplit: the source code is here.)

Why "Accepted Answer" works... but it wasn't enough for me

This works in the specification. At least swagger-tools (version 0.10.1) validates it as a valid.

But if you are using other tools like swagger-codegen (version 2.1.6) you will find some difficulties, even if the client generated contains the Authentication definition, like this:

this.authentications = {
  'Bearer': {type: 'apiKey', 'in': 'header', name: 'Authorization'}
};

There is no way to pass the token into the header before method(endpoint) is called. Look into this function signature:

this.rootGet = function(callback) { ... }

This means that, I only pass the callback (in other cases query parameters, etc) without a token, which leads to a incorrect build of the request to server.

My alternative

Unfortunately, it's not "pretty" but it works until I get JWT Tokens support on Swagger.

Note: which is being discussed in

• security: add support for Authorization header with Bearer authentication scheme #583
• Extensibility of security definitions? #460

So, it's handle authentication like a standard header. On path object append an header paremeter:

swagger: '2.0'
info:
  version: 1.0.0
  title: Based on "Basic Auth Example"
  description: >
    An example for how to use Auth with Swagger.

host: localhost
schemes:
  - http
  - https
paths:
  /:
    get:
      parameters:
        - 
          name: authorization
          in: header
          type: string
          required: true
      responses:
        '200':
          description: 'Will send `Authenticated`'
        '403': 
          description: 'You do not have necessary permissions for the resource'

This will generate a client with a new parameter on method signature:

this.rootGet = function(authorization, callback) {
  // ...
  var headerParams = {
    'authorization': authorization
  };
  // ...
}

To use this method in the right way, just pass the "full string"

// 'token' and 'cb' comes from elsewhere
var header = 'Bearer ' + token;
sdk.rootGet(header, cb);

And works.

As others have answered… div is a “block element” (now redefined as Flow Content) and span is an “inline element” (Phrasing Content). Yes, you may change the default presentation of these elements, but there is a difference between “flow” versus “block”, and “phrasing” versus “inline”.

An element classified as flow content can only be used where flow content is expected, and an element classified as phrasing content can be used where phrasing content is expected. Since all phrasing content is flow content, a phrasing element can also be used anywhere flow content is expected. The specs provide more detailed info.

All phrasing elements, such as strong and em, can only contain other phrasing elements: you can’t put a table inside a cite for instance. Most flow content such as div and li can contain all types of flow content (as well as phrasing content), but there are a few exceptions: p, pre, and th are examples of non-phrasing flow content (“block elements”) that can only contain phrasing content (“inline elements”). And of course there are the normal element restrictions such as dl and table only being allowed to contain certain elements.

While both div and p are non-phrasing flow content, the div can contain other flow content children (including more divs and ps). On the other hand, p may only contain phrasing content children. That means you can’t put a div inside a p, even though both are non-phrasing flow elements.

Now here’s the kicker. These semantic specifications are unrelated to how the element is displayed. Thus, if you have a div inside a span, you will get a validation error even if you have span {display: block;} and div {display: inline;} in your CSS.

Nowadays, you should use ERB::Util.url_encode or CGI.escape. The primary difference between them is their handling of spaces:

>> ERB::Util.url_encode("foo/bar? baz&")
=> "foo%2Fbar%3F%20baz%26"

>> CGI.escape("foo/bar? baz&")
=> "foo%2Fbar%3F+baz%26"

CGI.escape follows the CGI/HTML forms spec and gives you an application/x-www-form-urlencoded string, which requires spaces be escaped to +, whereas ERB::Util.url_encode follows RFC 3986, which requires them to be encoded as %20.

See "What's the difference between URI.escape and CGI.escape?" for more discussion.

You have the right idea, as documentation shows:

http://docs.jquery.com/CSS/css#namevalue

Are you sure you're correctly identify this with class or id?

For example, if your class is myElementClass

$('.myElementClass').css('text-align','center');

Also, I haven't worked with Firebug in a while, but are you looking at the dom and not the html? Your source isn't changed by javascript, but the dom is. Look in the dom tab and see if the change was applied.

You need parentheses:

print(2**100)

As user @aaracrr pointed out in a comment on another answer probably the best answer is to re-require the package with the same version constraint.

ie.

composer require vendor/package

or specifying a version constraint

composer require vendor/package:^1.0.0

Here is a plunker showing how you can use it with the ngClass directive.

I'm demonstrating with divs instead of imgs though.

Template:

<ul>
      <li><div [ngClass]="{'this-is-a-class': selectedIndex == 1}" (click)="setSelected(1)"> </div></li>
      <li><div [ngClass]="{'this-is-a-class': selectedIndex == 2}" (click)="setSelected(2)"> </div></li>
      <li><div [ngClass]="{'this-is-a-class': selectedIndex == 3}" (click)="setSelected(3)"> </div></li>
</ul>

TS:

export class App {
  selectedIndex = -1;

  setSelected(id: number) {
    this.selectedIndex = id;
  }
}

i know this is an old post, but i wanted to provide a JQuery plugin version and my code.

// Find the first occurrence of object in list, Similar to $.grep, but stops searching 
function findFirst(a,b){
var i; for (i = 0; i < a.length; ++i) { if (b(a[i], i)) return a[i]; } return undefined;
}

usage:

var product = $.findFirst(arrProducts, function(p) { return p.id == 10 });

Add the below mentioned attribute on the property in your model class.

Attribute = [DatabaseGenerated(DatabaseGeneratedOption.Computed)]
Reference = System.ComponentModel.DataAnnotations.Schema

Initially I forgot to add this attribute. So in my database the constraint was created like

ALTER TABLE [dbo].[TableName] ADD DEFAULT (getdate()) FOR [ColumnName]

and I added this attribute and updated my db then it got changed into

ALTER TABLE [dbo].[TableName] ADD CONSTRAINT [DF_dbo.TableName_ColumnName] DEFAULT (getdate()) FOR [ColumnName]

The short answer to print floating point numbers losslessly (such that they can be read back in to exactly the same number, except NaN and Infinity):

• If your type is float: use printf("%.9g", number).
• If your type is double: use printf("%.17g", number).

Do NOT use %f, since that only specifies how many significant digits after the decimal and will truncate small numbers. For reference, the magic numbers 9 and 17 can be found in float.h which defines FLT_DECIMAL_DIG and DBL_DECIMAL_DIG.

I would prefer AssertJ for this.

        assertThatExceptionOfType(ExpectedException.class)
        .isThrownBy(() -> {
            // method call
        }).withMessage("My message");

I faced the same problem when I renamed my repository on GitHub. I tried to push at which point I got the error

fatal: 'origin' does not appear to be a git repository
fatal: The remote end hung up unexpectedly

I had to change the URL using

git remote set-url origin ssh://[email protected]/username/newRepoName.git

After this all commands started working fine. You can check the change by using

git remote -v

In my case after successfull change it showed correct renamed repo in URL

[aniket@alok Android]$ git remote -v
origin  ssh://[email protected]/aniket91/TicTacToe.git (fetch)
origin  ssh://[email protected]/aniket91/TicTacToe.git (push)

A simple extension method for this would be:

    public static void AddParameter(this SqlCommand sqlCommand, string parameterName, 
        SqlDbType sqlDbType, object item)
    {
        sqlCommand.Parameters.Add(parameterName, sqlDbType).Value = item ?? DBNull.Value;
    }

I came late for this but I think this function makes exactly what OP requests. You can easily change the SENTENCE and the LIMIT values for different results.

function breakSentence(word, limit) {_x000D_
  const queue = word.split(' ');_x000D_
  const list = [];_x000D_
_x000D_
  while (queue.length) {_x000D_
    const word = queue.shift();_x000D_
_x000D_
    if (word.length >= limit) {_x000D_
      list.push(word)_x000D_
    }_x000D_
    else {_x000D_

The simplest solution is to apply Python str function to the column you are trying to loop through.

If you are using pandas, this can be implemented as:

dataframe['column_name']=dataframe['column_name'].apply(str)

But why don't I have to install a certificate locally for the site?

Well the code that you are using is explicitly designed to accept the certificate without doing any checks whatsoever. This is not good practice ... but if that is what you want to do, then (obviously) there is no need to install a certificate that your code is explicitly ignoring.

Shouldn't I have to install a certificate locally and load it for this program or is it downloaded behind the covers?

No, and no. See above.

Is the traffic between the client to the remote site still encrypted in transmission?

Yes it is. However, the problem is that since you have told it to trust the server's certificate without doing any checks, you don't know if you are talking to the real server, or to some other site that is pretending to be the real server. Whether this is a problem depends on the circumstances.

If we used the browser as an example, typically a browser doesn't ask the user to explicitly install a certificate for each ssl site visited.

The browser has a set of trusted root certificates pre-installed. Most times, when you visit an "https" site, the browser can verify that the site's certificate is (ultimately, via the certificate chain) secured by one of those trusted certs. If the browser doesn't recognize the cert at the start of the chain as being a trusted cert (or if the certificates are out of date or otherwise invalid / inappropriate), then it will display a warning.

Java works the same way. The JVM's keystore has a set of trusted certificates, and the same process is used to check the certificate is secured by a trusted certificate.

Does the java https client api support some type of mechanism to download certificate information automatically?

No. Allowing applications to download certificates from random places, and install them (as trusted) in the system keystore would be a security hole.

You need the return so the true/false gets passed up to the form's submit event (which looks for this and prevents submission if it gets a false).

Lets look at some standard JS:

function testReturn() { return false; }

If you just call that within any other code (be it an onclick handler or in JS elsewhere) it will get back false, but you need to do something with that value.

...
testReturn()
...

In that example the return value is coming back, but nothing is happening with it. You're basically saying execute this function, and I don't care what it returns. In contrast if you do this:

...
var wasSuccessful = testReturn();
...

then you've done something with the return value.

The same applies to onclick handlers. If you just call the function without the return in the onsubmit, then you're saying "execute this, but don't prevent the event if it return false." It's a way of saying execute this code when the form is submitted, but don't let it stop the event.

Once you add the return, you're saying that what you're calling should determine if the event (submit) should continue.

This logic applies to many of the onXXXX events in HTML (onclick, onsubmit, onfocus, etc).

The first answer is good for understanding how it works. But I wanted to understand how I should be using it in practice.

SUMMARY

• for moderately imbalanced data WITHOUT noise, there is not much of a difference in applying class weights
• for moderately imbalanced data WITH noise and strongly imbalanced, it is better to apply class weights
• param class_weight="balanced" works decent in the absence of you wanting to optimize manually
• with class_weight="balanced" you capture more true events (higher TRUE recall) but also you are more likely to get false alerts (lower TRUE precision)
  • as a result, the total % TRUE might be higher than actual because of all the false positives
  • AUC might misguide you here if the false alarms are an issue
• no need to change decision threshold to the imbalance %, even for strong imbalance, ok to keep 0.5 (or somewhere around that depending on what you need)

NB

The result might differ when using RF or GBM. sklearn does not have class_weight="balanced" for GBM but lightgbm has LGBMClassifier(is_unbalance=False)

If you're using Xamarin, I found a guide on their official forum explaining how to do this:

1. Download the package from the internet. There are many sources for this, one possible source is the CyanogenMod web site.
2. Start up the Android Player and unlock it.
3. Drag and drop the zip file that you downloaded onto the Android Player.
4. Restart the Android Player.

Hereafter, you might also need to update the Google Play Services from the Google Play Store.

Hope this helps for anyone else who has troubles finding the documentation.

From the manual:

Possible values for the parameter timeout: … x set timeout to x seconds

and

readlines(sizehint=None, eol='\n') Read a list of lines, until timeout. sizehint is ignored and only present for API compatibility with built-in File objects.

Note that this function only returns on a timeout.

So your readlines will return at most every 2 seconds. Use read() as Tim suggested.

Arduino sketches are written in C++.

Here is a typical construct you'll encounter:

LiquidCrystal lcd(12, 11, 5, 4, 3, 2);
...
lcd.begin(16, 2);
lcd.print("Hello, World!");

That's C++, not C.

Hence do yourself a favor and learn C++. There are plenty of books and online resources available.

To install Python package from github, you need to clone that repository.

git clone https://github.com/jkbr/httpie.git

Then just run the setup.py file from that directory,

sudo python setup.py install

I would do it this way:

import sys

def main(argv):
    if len(argv) < 2:
        sys.stderr.write("Usage: %s <database>" % (argv[0],))
        return 1

    if not os.path.exists(argv[1]):
        sys.stderr.write("ERROR: Database %r was not found!" % (argv[1],))
        return 1

if __name__ == "__main__":
    sys.exit(main(sys.argv))

This allows main() to be imported into other modules if desired, and simplifies debugging because you can choose what argv should be.

I get a slightly different error, though perhaps related, on Ubuntu 12.04:

Gem::RemoteFetcher::FetchError: SSL_connect returned=1 errno=0 state=unknown state: sslv3 alert handshake failure (https://d2chzxaqi4y7f8.cloudfront.net/gems/activesupport-3.2.3.gem)
An error occured while installing activesupport (3.2.3), and Bundler cannot continue.
Make sure that `gem install activesupport -v '3.2.3'` succeeds before bundling.

It happens when I run bundle install with source 'https://rubygems.org' in a Gemfile.

This is an issue with OpenSSL on Ubuntu 12.04. See Rubygems issue #319.

To fix this, run apt-get update && apt-get upgrade on Ubuntu 12.04 to upgrade your OpenSSL.

Getting some sort of modification date in a cross-platform way is easy - just call os.path.getmtime(path) and you'll get the Unix timestamp of when the file at path was last modified.

Getting file creation dates, on the other hand, is fiddly and platform-dependent, differing even between the three big OSes:

• On Windows, a file's ctime (documented at https://msdn.microsoft.com/en-us/library/14h5k7ff.aspx) stores its creation date. You can access this in Python through os.path.getctime() or the .st_ctime attribute of the result of a call to os.stat(). This won't work on Unix, where the ctime is the last time that the file's attributes or content were changed.
• On Mac, as well as some other Unix-based OSes, you can use the .st_birthtime attribute of the result of a call to os.stat().

• On Linux, this is currently impossible, at least without writing a C extension for Python. Although some file systems commonly used with Linux do store creation dates (for example, ext4 stores them in st_crtime) , the Linux kernel offers no way of accessing them; in particular, the structs it returns from stat() calls in C, as of the latest kernel version, don't contain any creation date fields. You can also see that the identifier st_crtime doesn't currently feature anywhere in the Python source. At least if you're on ext4, the data is attached to the inodes in the file system, but there's no convenient way of accessing it.

  The next-best thing on Linux is to access the file's mtime, through either os.path.getmtime() or the .st_mtime attribute of an os.stat() result. This will give you the last time the file's content was modified, which may be adequate for some use cases.

Putting this all together, cross-platform code should look something like this...

import os
import platform

def creation_date(path_to_file):
    """
    Try to get the date that a file was created, falling back to when it was
    last modified if that isn't possible.
    See http://stackoverflow.com/a/39501288/1709587 for explanation.
    """
    if platform.system() == 'Windows':
        return os.path.getctime(path_to_file)
    else:
        stat = os.stat(path_to_file)
        try:
            return stat.st_birthtime
        except AttributeError:
            # We're probably on Linux. No easy way to get creation dates here,
            # so we'll settle for when its content was last modified.
            return stat.st_mtime

When you run

install.packages("whatever")

you got message that your binaries are downloaded into temporary location (e.g. The downloaded binary packages are in C:\Users\User_name\AppData\Local\Temp\RtmpC6Y8Yv\downloaded_packages ). Go there. Take binaries (zip file). Copy paste into location which you get from running the code:

.libPaths()

If libPaths shows 2 locations, then paste into second one. Load library:

library(whatever)

Fixed.

Doing unions in MongoDB in a 'SQL UNION' fashion is possible using aggregations along with lookups, in a single query. Here is an example I have tested that works with MongoDB 4.0:

// Create employees data for testing the union.
db.getCollection('employees').insert({ name: "John", type: "employee", department: "sales" });
db.getCollection('employees').insert({ name: "Martha", type: "employee", department: "accounting" });
db.getCollection('employees').insert({ name: "Amy", type: "employee", department: "warehouse" });
db.getCollection('employees').insert({ name: "Mike", type: "employee", department: "warehouse"  });

// Create freelancers data for testing the union.
db.getCollection('freelancers').insert({ name: "Stephany", type: "freelancer", department: "accounting" });
db.getCollection('freelancers').insert({ name: "Martin", type: "freelancer", department: "sales" });
db.getCollection('freelancers').insert({ name: "Doug", type: "freelancer", department: "warehouse"  });
db.getCollection('freelancers').insert({ name: "Brenda", type: "freelancer", department: "sales"  });

// Here we do a union of the employees and freelancers using a single aggregation query.
db.getCollection('freelancers').aggregate( // 1. Use any collection containing at least one document.
  [
    { $limit: 1 }, // 2. Keep only one document of the collection.
    { $project: { _id: '$$REMOVE' } }, // 3. Remove everything from the document.

    // 4. Lookup collections to union together.
    { $lookup: { from: 'employees', pipeline: [{ $match: { department: 'sales' } }], as: 'employees' } },
    { $lookup: { from: 'freelancers', pipeline: [{ $match: { department: 'sales' } }], as: 'freelancers' } },

    // 5. Union the collections together with a projection.
    { $project: { union: { $concatArrays: ["$employees", "$freelancers"] } } },

    // 6. Unwind and replace root so you end up with a result set.
    { $unwind: '$union' },
    { $replaceRoot: { newRoot: '$union' } }
  ]);

Here is the explanation of how it works:

1. Instantiate an aggregate out of any collection of your database that has at least one document in it. If you can't guarantee any collection of your database will not be empty, you can workaround this issue by creating in your database some sort of 'dummy' collection containing a single empty document in it that will be there specifically for doing union queries.

2. Make the first stage of your pipeline to be { $limit: 1 }. This will strip all the documents of the collection except the first one.

3. Strip all the fields of the remaining document by using a $project stage:

   { $project: { _id: '$$REMOVE' } }
   

4. Your aggregate now contains a single, empty document. It's time to add lookups for each collection you want to union together. You may use the pipeline field to do some specific filtering, or leave localField and foreignField as null to match the whole collection.

   { $lookup: { from: 'collectionToUnion1', pipeline: [...], as: 'Collection1' } },
   { $lookup: { from: 'collectionToUnion2', pipeline: [...], as: 'Collection2' } },
   { $lookup: { from: 'collectionToUnion3', pipeline: [...], as: 'Collection3' } }
   

5. You now have an aggregate containing a single document that contains 3 arrays like this:

   {
       Collection1: [...],
       Collection2: [...],
       Collection3: [...]
   }
   

   You can then merge them together into a single array using a $project stage along with the $concatArrays aggregation operator:

   {
     "$project" :
     {
       "Union" : { $concatArrays: ["$Collection1", "$Collection2", "$Collection3"] }
     }
   }
   

6. You now have an aggregate containing a single document, into which is located an array that contains your union of collections. What remains to be done is to add an $unwind and a $replaceRoot stage to split your array into separate documents:

   { $unwind: "$Union" },
   { $replaceRoot: { newRoot: "$Union" } }
   

7. Voilà. You now have a result set containing the collections you wanted to union together. You can then add more stages to filter it further, sort it, apply skip() and limit(). Pretty much anything you want.

(this answer was added to provide shorter and more generic examples to the question - without including all the case-specific details in the original question).

There are two distinct "problems" here, the first is if a table or subquery has no rows, the second is if there are NULL values in the query.

For all versions I've tested, postgres and mysql will ignore all NULL values when averaging, and it will return NULL if there is nothing to average over. This generally makes sense, as NULL is to be considered "unknown". If you want to override this you can use coalesce (as suggested by Luc M).

$ create table foo (bar int);
CREATE TABLE

$ select avg(bar) from foo;
 avg 
-----

(1 row)

$ select coalesce(avg(bar), 0) from foo;
 coalesce 
----------
        0
(1 row)

$ insert into foo values (3);
INSERT 0 1
$ insert into foo values (9);
INSERT 0 1
$ insert into foo values (NULL);
INSERT 0 1
$ select coalesce(avg(bar), 0) from foo;
      coalesce      
--------------------
 6.0000000000000000
(1 row)

of course, "from foo" can be replaced by "from (... any complicated logic here ...) as foo"

Now, should the NULL row in the table be counted as 0? Then coalesce has to be used inside the avg call.

$ select coalesce(avg(coalesce(bar, 0)), 0) from foo;
      coalesce      
--------------------
 4.0000000000000000
(1 row)

I developed my own SQL Server 2016+ JSON parser a while ago. I use this in all my projects - very good performance. I hope it can help someone else too.

Another similar method to those described above is to use plt.ylim for example:

plt.ylim(max(y_array), min(y_array))

This method works for me when I'm attempting to compound multiple datasets on Y1 and/or Y2

Add the below css as per you want your screen width.

@media (min-width: 991px){
    .modal-dialog {
        margin: 0px 179px !important;
    }
}

You could use dplyr:

df %>% group_by("Amount") %>% slice(which.min(x))

Mixed Subtype

The "mixed" subtype of "multipart" is intended for use when the body parts are independent and need to be bundled in a particular order. Any "multipart" subtypes that an implementation does not recognize must be treated as being of subtype "mixed".

Alternative Subtype

The "multipart/alternative" type is syntactically identical to "multipart/mixed", but the semantics are different. In particular, each of the body parts is an "alternative" version of the same information

Source

you can use this code as template please customize it as per your requirement.

DefaultTableModel model = new DefaultTableModel();
List<String> list = new ArrayList<String>();

list.add(textField.getText());
list.add(comboBox.getSelectedItem());

model.addRow(list.toArray());

table.setModel(model);

here DefaultTableModel is used to add rows in JTable, you can get more info here.

You can use the List.addAll() method. It accepts a Collection as an argument, and your set is a Collection.

List<String> mainList = new ArrayList<String>();
mainList.addAll(set);

EDIT: as respond to the edit of the question.
It is easy to see that if you want to have a Map with Lists as values, in order to have k different values, you need to create k different lists.
Thus: You cannot avoid creating these lists at all, the lists will have to be created.

Possible work around:
Declare your Map as a Map<String,Set> or Map<String,Collection> instead, and just insert your set.

This will work for sure

What I did was I uninstalled Java from my PC, and then downloaded and installed JDK again from Oracle. After this it worked perfectly. I think the problem was because the JRE and JDK update version were different from each other.

Contrary to Mark Novakowski answer, which for some reason has been upvoted by many, yes, it is a valid and satisfiable request.

In fact the standard, as Wrikken pointed out, makes just such an example. In practice, Apache responds to such requests as expected (with a 206 code), and this is exactly what I use to implement progressive download, that is, only get the tail of a long log file which grows in real time with polling.

In my case this was actually a symptom of the server, hosted on AWS, lacking an IP for the external network. It would attempt to download namespaces from springframework.org and fail to make a connection.

From the documentation on expandtab:

To insert a real tab when expandtab is on, use CTRL-V<Tab>. See also :retab and ins-expandtab.
This option is reset when the paste option is set and restored when the paste option is reset.

So if you have a mapping for toggling the paste option, e.g.

set pastetoggle=<F2>

you could also do <F2>Tab<F2>.

In most of the companies they required a common functionality for multiple dropdownlist for all the pages. Just call the functions or pass your (DropDownID,JsonData,KeyValue,textValue)

    <script>

        $(document).ready(function(){

            GetData('DLState',data,'stateid','statename');
        });

        var data = [{"stateid" : "1","statename" : "Mumbai"},
                    {"stateid" : "2","statename" : "Panjab"},
                    {"stateid" : "3","statename" : "Pune"},
                     {"stateid" : "4","statename" : "Nagpur"},
                     {"stateid" : "5","statename" : "kanpur"}];

        var Did=document.getElementById("DLState");

        function GetData(Did,data,valkey,textkey){
          var str= "";
          for (var i = 0; i <data.length ; i++){

            console.log(data);


            str+= "<option value='" + data[i][valkey] + "'>" + data[i][textkey] + "</option>";

          }
          $("#"+Did).append(str);
        };    </script>

</head>
<body>
  <select id="DLState">
  </select>
</body>
</html>

The following will create a simple stored procedure that uses a cursor to kill all processes one by one except for the process currently being used:

DROP PROCEDURE IF EXISTS kill_other_processes;

DELIMITER $$

CREATE PROCEDURE kill_other_processes()
BEGIN
  DECLARE finished INT DEFAULT 0;
  DECLARE proc_id INT;
  DECLARE proc_id_cursor CURSOR FOR SELECT id FROM information_schema.processlist;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET finished = 1;

  OPEN proc_id_cursor;
  proc_id_cursor_loop: LOOP
    FETCH proc_id_cursor INTO proc_id;

    IF finished = 1 THEN 
      LEAVE proc_id_cursor_loop;
    END IF;

    IF proc_id <> CONNECTION_ID() THEN
      KILL proc_id;
    END IF;

  END LOOP proc_id_cursor_loop;
  CLOSE proc_id_cursor;
END$$

DELIMITER ;

It can be run with SELECTs to show the processes before and after as follows:

SELECT * FROM information_schema.processlist;
CALL kill_other_processes();
SELECT * FROM information_schema.processlist;

In the application/config folder, get the file config.php and check for the below:

$config['time_reference'] = '';

Change the value to your preferred time zone. For example to set time zone to Nairobi Kenya: $config['time_reference'] = 'Africa/Nairobi';

You can try something like this..

CREATE TABLE 'sample'.'picture' ( 
'idpicture' INTEGER UNSIGNED NOT NULL AUTO_INCREMENT, 
'caption' VARCHAR(45) NOT NULL, 
'img' LONGBLOB NOT NULL, 
 PRIMARY KEY('idpicture')) TYPE = InnoDB;

If I understand right, you've made a commit to changed_branch and you want to copy that commit to other_branch? Easy:

git checkout other_branch
git cherry-pick changed_branch

Solution : SpreadsheetApp.getActiveSheet().getRange('F2').setValue('hello')

Explanation :

Setting value in a cell in spreadsheet to which script is attached

SpreadsheetApp.getActiveSpreadsheet().getSheetByName(SHEET_NAME).getRange(RANGE).setValue(VALUE);

Setting value in a cell in sheet which is open currently and to which script is attached

SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getRange(RANGE).setValue(VALUE);

Setting value in a cell in some spreadsheet to which script is NOT attached (Destination sheet name known)

SpreadsheetApp.openById(SHEET_ID).getSheetByName(SHEET_NAME).getRange(RANGE).setValue(VALUE);

Setting value in a cell in some spreadsheet to which script is NOT attached (Destination sheet position known)

SpreadsheetApp.openById(SHEET_ID).getSheets()[POSITION].getRange(RANGE).setValue(VALUE);

These are constants, you must define them yourself

SHEET_ID

SHEET_NAME

POSITION

VALUE

RANGE

By script attached to a sheet I mean that script is residing in the script editor of that sheet. Not attached means not residing in the script editor of that sheet. It can be in any other place.

The third parameter of String.prototype.replace() function was never defined as a standard, so most browsers simply do not implement it.

The best way is to use regular expression with g (global) flag.

var myStr = 'this,is,a,test';_x000D_
var newStr = myStr.replace(/,/g, '-');_x000D_
_x000D_
console.log( newStr );  // "this-is-a-test"

Still have issues?

It is important to note, that regular expressions use special characters that need to be escaped. As an example, if you need to escape a dot (.) character, you should use /\./ literal, as in the regex syntax a dot matches any single character (except line terminators).

var myStr = 'this.is.a.test';_x000D_
var newStr = myStr.replace(/\./g, '-');_x000D_
_x000D_
console.log( newStr );  // "this-is-a-test"

If you need to pass a variable as a replacement string, instead of using regex literal you may create RegExp object and pass a string as the first argument of the constructor. The normal string escape rules (preceding special characters with \ when included in a string) will be necessary.

var myStr = 'this.is.a.test';_x000D_
var reStr = '\\.';_x000D_
var newStr = myStr.replace(new RegExp(reStr, 'g'), '-');_x000D_
_x000D_
console.log( newStr );  // "this-is-a-test"

any and ord can be combined to serve the purpose as shown below.

>>> def hasDigits(s):
...     return any( 48 <= ord(char) <= 57 for char in s)
...
>>> hasDigits('as1')
True
>>> hasDigits('as')
False
>>> hasDigits('as9')
True
>>> hasDigits('as_')
False
>>> hasDigits('1as')
True
>>>

A couple of points about this implementation.

1. any is better because it works like short circuit expression in C Language and will return result as soon as it can be determined i.e. in case of string 'a1bbbbbbc' 'b's and 'c's won't even be compared.

2. ord is better because it provides more flexibility like check numbers only between '0' and '5' or any other range. For example if you were to write a validator for Hexadecimal representation of numbers you would want string to have alphabets in the range 'A' to 'F' only.

you need only set default value to parameters(you do not need the Route attribute):

public IHttpActionResult Get(string apc = null, string xpc = null, int? sku = null)
{ ... }

RDBMS focus more on relationship and NoSQL focus more on storage.

You can consider using NoSQL when your RDBMS reaches bottlenecks. NoSQL makes RDBMS more flexible.

If You Have Multiple li elements inside an li element then this will definitely help you, and i have checked it and it works....

<script>
$("li").on('click', function() {
          alert(this.id);
          return false;
      });
</script>

There are certain scenarios in which you can follow the steps suggested in the other answers, verify that Execution Policy is set correctly, and still have your scripts fail. If this happens to you, you are probably on a 64-bit machine with both 32-bit and 64-bit versions of PowerShell, and the failure is happening on the version that doesn't have Execution Policy set. The setting does not apply to both versions, so you have to explicitly set it twice.

Look in your Windows directory for System32 and SysWOW64.

Repeat these steps for each directory:

1. Navigate to WindowsPowerShell\v1.0 and launch powershell.exe

2. Check the current setting for ExecutionPolicy:

   Get-ExecutionPolicy -List

3. Set the ExecutionPolicy for the level and scope you want, for example:

   Set-ExecutionPolicy -Scope LocalMachine Unrestricted

Note that you may need to run PowerShell as administrator depending on the scope you are trying to set the policy for.

YES - solution is to save workbook in to XML file (eg. 'XML Spreadsheet 2003') and edit this file as text in notepad! use "SEARCH" function of notepad to find query text and change your data to "?".

save and open in excel, try refresh data and excel will be monit about parameters.

In a special case within ASP.NET If you want to know if the page is redirected by a specified .aspx page and not another one, just put the information in a session name and take necessary action in the receiving Page_Load Event.
