When doing a getObject() from the S3 API, per the docs the contents of your file are located in the Body property, which you can see from your sample output. You should have code that looks something like the following

const aws = require('aws-sdk');
const s3 = new aws.S3(); // Pass in opts to S3 if necessary

var getParams = {
    Bucket: 'abc', // your bucket name,
    Key: 'abc.txt' // path to the object you're looking for
}

s3.getObject(getParams, function(err, data) {
    // Handle any error and exit
    if (err)
        return err;

  // No error happened
  // Convert Body from a Buffer to a String

  let objectData = data.Body.toString('utf-8'); // Use the encoding necessary
});

You may not need to create a new buffer from the data.Body object but if you need you can use the sample above to achieve that.

Simplest bullet-and-fool-proof way of doing a complete rename (including dropping the old database at the end so it's a rename rather than a copy):

mysqladmin -uroot -pmypassword create newdbname
mysqldump -uroot -pmypassword --routines olddbname | mysql -uroot -pmypassword newdbname
mysqladmin -uroot -pmypassword drop olddbname

Steps:

1. Copy the lines into Notepad.
2. Replace all references to "olddbname", "newdbname", "mypassword" (+ optionally "root") with your equivalents.
3. Execute one by one on the command line (entering "y" when prompted).

RxJS Operators are functions that build on the observables foundation to enable sophisticated manipulation of collections.

For example, RxJS defines operators such as map(), filter(), concat(), and flatMap().

You can use pipes to link operators together. Pipes let you combine multiple functions into a single function.

The pipe() function takes as its arguments the functions you want to combine, and returns a new function that, when executed, runs the composed functions in sequence.

I completely agree with mercenary's answer posted above and created this function for me which works for me. It's not an answer, it's a comment on above post by mercenary

function openWindowWithPostRequest() {
  var winName='MyWindow';
  var winURL='search.action';
  var windowoption='resizable=yes,height=600,width=800,location=0,menubar=0,scrollbars=1';
  var params = { 'param1' : '1','param2' :'2'};         
  var form = document.createElement("form");
  form.setAttribute("method", "post");
  form.setAttribute("action", winURL);
  form.setAttribute("target",winName);  
  for (var i in params) {
    if (params.hasOwnProperty(i)) {
      var input = document.createElement('input');
      input.type = 'hidden';
      input.name = i;
      input.value = params[i];
      form.appendChild(input);
    }
  }              
  document.body.appendChild(form);                       
  window.open('', winName,windowoption);
  form.target = winName;
  form.submit();                 
  document.body.removeChild(form);           
}

This code works for me:

public void Run()
{
    Dog myDog = new Dog();
    myDog.Name= "Foo";
    myDog.Color = DogColor.Brown;

    System.Console.WriteLine("{0}", myDog.ToString());

    MemoryStream stream = SerializeToStream(myDog);

    Dog newDog = (Dog)DeserializeFromStream(stream);

    System.Console.WriteLine("{0}", newDog.ToString());
}

Where the types are like this:

[Serializable]
public enum DogColor
{
    Brown,
    Black,
    Mottled
}

[Serializable]
public class Dog
{
    public String Name
    {
        get; set;
    }

    public DogColor Color
    {
        get;set;
    }

    public override String ToString()
    {
        return String.Format("Dog: {0}/{1}", Name, Color);
    }
}

and the utility methods are:

public static MemoryStream SerializeToStream(object o)
{
    MemoryStream stream = new MemoryStream();
    IFormatter formatter = new BinaryFormatter();
    formatter.Serialize(stream, o);
    return stream;
}

public static object DeserializeFromStream(MemoryStream stream)
{
    IFormatter formatter = new BinaryFormatter();
    stream.Seek(0, SeekOrigin.Begin);
    object o = formatter.Deserialize(stream);
    return o;
}

if you use apiLevel >= 19, don't use

WindowManager.LayoutParams.type = WindowManager.LayoutParams.TYPE_SYSTEM_ALERT 

which gets the following error:

android.view.WindowManager$BadTokenException: Unable to add window android.view.ViewRootImpl$W@40ec8528 -- permission denied for this window type

Use this instead:

LayoutParams.TYPE_TOAST or TYPE_APPLICATION_PANEL

Something like this should do:

function cleanLocalStorage() {
    for(key in localStorage) {
        delete localStorage[key];
    }
}

Be careful about using this, though, as the user may have other data stored in localStorage and would probably be pretty ticked if you deleted that. I'd recommend either a) not storing the user's data in localStorage or b) storing the user's account stuff in a single variable, and then clearing that instead of deleting all the keys in localStorage.

Edit: As Lyn pointed out, you'll be good with localStorage.clear(). My previous points still stand, however.

For those who don't want to create any models, use the following code:

var result = JsonConvert.DeserializeObject<
  List<Dictionary<string, 
    Dictionary<string, string>>>>(content);

Note: This doesn't work for your JSON string. This is not a general solution for any JSON structure.

Normally you would select IDs using the ID selector #, but for more complex matches you can use the attribute-starts-with selector (as a jQuery selector, or as a CSS3 selector):

div[id^="player_"]

If you are able to modify that HTML, however, you should add a class to your player divs then target that class. You'll lose the additional specificity offered by ID selectors anyway, as attribute selectors share the same specificity as class selectors. Plus, just using a class makes things much simpler.

You can create a trigger which updates NoofUses column in Coupon table whenever couponid is used in CouponUse table

query :

CREATE TRIGGER [dbo].[couponcount] ON [dbo].[couponuse]
FOR INSERT
AS
if EXISTS (SELECT 1 FROM Inserted)
  BEGIN
UPDATE dbo.Coupon
SET NoofUses = (SELECT COUNT(*) FROM dbo.CouponUse WHERE Couponid = dbo.Coupon.ID)
end 

Using GhostScript from the command line, I've used the following in the past:

on Windows:

gswin32c -dNOPAUSE -q -g300x300 -sDEVICE=tiffg4 -dBATCH -sOutputFile=output_file_name.tif input_file_name.pdf

on *nix:

gs -dNOPAUSE -q -g300x300 -sDEVICE=tiffg4 -dBATCH -sOutputFile=output_file_name.tif input_file_name.pdf

For a large number of files, a simple batch/shell script could be used to convert an arbitrary number of files...

Looks like YouTube has updated their JS API so this is available by default! You can use an existing YouTube iframe's ID...

<iframe id="player" src="http://www.youtube.com/embed/M7lc1UVf-VE?enablejsapi=1&origin=http://example.com" frameborder="0"></iframe>

...in your JS...

var player;
function onYouTubeIframeAPIReady() {
  player = new YT.Player('player', {
    events: {
      'onStateChange': onPlayerStateChange
    }
  });
}

function onPlayerStateChange() {
  //...
}

...and the constructor will use your existing iframe instead of replacing it with a new one. This also means you don't have to specify the videoId to the constructor.

See Loading a video player

You can implement UINavigationControllerDelegate like this:

Older Swift

func navigationController(navigationController: UINavigationController, willShowViewController viewController: UIViewController, animated: Bool) {
    let item = UIBarButtonItem(title: " ", style: .Plain, target: nil, action: nil)
    viewController.navigationItem.backBarButtonItem = item
}

Swift 4.x

class MyNavigationController: UINavigationController, UINavigationControllerDelegate {
    override func viewDidLoad() {
        super.viewDidLoad()
        self.delegate = self
    }

    func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
        let item = UIBarButtonItem(title: " ", style: .plain, target: nil, action: nil)
        viewController.navigationItem.backBarButtonItem = item
    }
}

backBarButtonItem is nil by default and it affects next pushed controller, so you just set it for all controllers

I think you're not using GROUP BY properly.

The point of GROUP BY is to organize your table into sections based off a certain column or columns before performing math/aggregate functions.

For example, in this table:

Name    Age   Salary
Bob     25     20000
Sally   42     40000
John    42     90000

A SELECT statement could GROUP BY name (Bob, Sally, and John would each be separate groups), Age (Bob would be one group, Sally and John would be another), or Salary (pretty much same result as name).

Grouping by "1" doesn't make any sense because "1" is not a column name.

For some looking for a solution to this problem, the root of the issue may be where you are setting your list views adapter. After you set the adapter on the listview, it resets the scroll position. Just something to consider. I moved setting the adapter into my onCreateView after we grab the reference to the listview, and it solved the problem for me. =)

For those who didn't know what next, just add new module file and put @jor code (with my little hacked, supporting 'nothing' array) below.

Module ArrayExtension
    <Extension()> _
    Public Sub Add(Of T)(ByRef arr As T(), item As T)
        If arr IsNot Nothing Then
            Array.Resize(arr, arr.Length + 1)
            arr(arr.Length - 1) = item
        Else
            ReDim arr(0)
            arr(0) = item
        End If

    End Sub
End Module

In you app config file change the url to localhost/example/public

Then when you want to link to something

<a href="{{ url('page') }}">Some Text</a>

without blade

<a href="<?php echo url('page') ?>">Some Text</a>

There are different ways to close the app, depending on:

if (navigator.app) {
    navigator.app.exitApp();
} else if (navigator.device) {
    navigator.device.exitApp();
} else {
    window.close();
}

Simple Css work for me

.modal-dialog { 
max-width : 100% ;
}

You can use this pod called 'SVGParser'. https://cocoapods.org/pods/SVGParser.

After adding it in your pod file, all you have to do is to import this module to the class that you want to use it. You should show the SVG image in an ImageView.

There are three cases you can show this SVGimage:

1. Load SVG from local path as Data
2. Load SVG from local path
3. Load SVG from remote URL

You can also find an example project in GitHub: https://github.com/AndreyMomot/SVGParser. Just download the project and run it to see how it works.

While xrange is faster than range in most circumstances, the difference in performance is pretty minimal. The little program below compares iterating over a range and an xrange:

import timeit
# Try various list sizes.
for list_len in [1, 10, 100, 1000, 10000, 100000, 1000000]:
  # Time doing a range and an xrange.
  rtime = timeit.timeit('a=0;\nfor n in range(%d): a += n'%list_len, number=1000)
  xrtime = timeit.timeit('a=0;\nfor n in xrange(%d): a += n'%list_len, number=1000)
  # Print the result
  print "Loop list of len %d: range=%.4f, xrange=%.4f"%(list_len, rtime, xrtime)

The results below shows that xrange is indeed faster, but not enough to sweat over.

Loop list of len 1: range=0.0003, xrange=0.0003
Loop list of len 10: range=0.0013, xrange=0.0011
Loop list of len 100: range=0.0068, xrange=0.0034
Loop list of len 1000: range=0.0609, xrange=0.0438
Loop list of len 10000: range=0.5527, xrange=0.5266
Loop list of len 100000: range=10.1666, xrange=7.8481
Loop list of len 1000000: range=168.3425, xrange=155.8719

So by all means use xrange, but unless you're on a constrained hardware, don't worry too much about it.

EntityFunctions is obsolete. Consider using DbFunctions instead.

var eventsCustom = eventCustomRepository.FindAllEventsCustomByUniqueStudentReference(userDevice.UniqueStudentReference)
   .Where(x => DbFunctions.TruncateTime(x.DateTimeStart) == currentDate.Date);

Here's how to change the dosbox.conf file in Linux to increase the size of the window. I actually DID what follows, so I can say it works (in 32-bit PCLinuxOS fullmontyKDE, anyway). The question's answer is in the .conf file itself.

You find this file in Linux at /home/(username)/.dosbox . In Konqueror or Dolphin, you must first check 'Hidden files' or you won't see the folder. Open it with KWrite superuser or your fav editor.

1. Save the file with another name like 'dosbox-0.74original.conf' to preserve the original file in case you need to restore it.
2. Search on 'resolution' and carefully read what the conf file says about changing it. There are essentially two variables: resolution and output. You want to leave fullresolution alone for now. Your question was about WINDOW, not full. So look for windowresolution, see what the comments in conf file say you can do. The best suggestion is to use a bigger-window resolution like 900x800 (which is what I used on a 1366x768 screen), but NOT the actual resolution of your machine (which would make the window fullscreen, and you said you didn't want that). Be specific, replacing the 'windowresolution=original' with 'windowresolution=900x800' or other dimensions. On my screen, that doubled the window size just as it does with the max Font tab in Windows Properties (for the exe file; as you'll see below the ==== marks, 32-bit Windows doesn't need Dosbox).

Then, search on 'output', and as the instruction in the conf file warns, if and only if you have 'hardware scaling', change the default 'output=surface' to something else; he then lists the optional other settings. I changed it to 'output=overlay'. There's one other setting to test: aspect. Search the file for 'aspect', and change the 'false' to 'true' if you want an even bigger window. When I did this, the window took up over half of the screen. With 'false' left alone, I had a somewhat smaller window (I use widescreen monitors, whether laptop or desktop, maybe that's why).

So after you've made the changes, save the file with the original name of dosbox-0.74.conf . Then, type dosbox at the command line or create a Launcher (in KDE, this is a right click on the desktop) with the command dosbox. You still have to go through the mount command (i.e., mount c~ c:\123 if that's the location and file you'll execute). I'm sure there's a way to make a script, but haven't yet learned how to do that.

I know this has an accepted answer but if anyone comes upon this, my solution may help.

I found this question because I have a use-case where I wanted to turn off the :hover state for elements individually. Since there is no way to do this in the DOM, another good way to do it is to define a class in CSS that overrides the hover state.

For instance, the css:

.nohover:hover {
    color: black !important;
}

Then with jQuery:

$("#elm").addClass("nohover");

With this method, you can override as many DOM elements as you would like without binding tons of onHover events.

Here is the sample on what worked for me. I think that put method is needed in entity class to map sql columns to java class attributes.

    //simpleExample
    Query query = em.createNativeQuery(
"SELECT u.name,s.something FROM user u,  someTable s WHERE s.user_id = u.id", 
NameSomething.class);
    List list = (List<NameSomething.class>) query.getResultList();

Entity class:

    @Entity
    public class NameSomething {

        @Id
        private String name;

        private String something;

        // getters/setters



        /**
         * Generic put method to map JPA native Query to this object.
         *
         * @param column
         * @param value
         */
        public void put(Object column, Object value) {
            if (((String) column).equals("name")) {
                setName(String) value);
            } else if (((String) column).equals("something")) {
                setSomething((String) value);
            }
        }
    }

Usefull fallback here: https://developer.mozilla.org/en-US/docs/Web/Events/MozOrientation

function orientationhandler(evt){


  // For FF3.6+
  if (!evt.gamma && !evt.beta) {
    evt.gamma = -(evt.x * (180 / Math.PI));
    evt.beta = -(evt.y * (180 / Math.PI));
  }

  // use evt.gamma, evt.beta, and evt.alpha 
  // according to dev.w3.org/geo/api/spec-source-orientation


}

window.addEventListener('deviceorientation',  orientationhandler, false);
window.addEventListener('MozOrientation',     orientationhandler, false);

What the error is telling, is that you can't convert an entire list into an integer. You could get an index from the list and convert that into an integer:

x = ["0", "1", "2"] 
y = int(x[0]) #accessing the zeroth element

If you're trying to convert a whole list into an integer, you are going to have to convert the list into a string first:

x = ["0", "1", "2"]
y = ''.join(x) # converting list into string
z = int(y)

If your list elements are not strings, you'll have to convert them to strings before using str.join:

x = [0, 1, 2]
y = ''.join(map(str, x))
z = int(y)

Also, as stated above, make sure that you're not returning a nested list.

There are two obvious points, as well as the points in the other answer:

• They are exactly equivalent when using sub queries:

  SELECT * FROM table
  WHERE column IN(subquery);
  
  SELECT * FROM table
  WHERE column = ANY(subquery);
  

On the other hand:

• Only the IN operator allows a simple list:

  SELECT * FROM table
  WHERE column IN(… , … , …);
  

Presuming they are exactly the same has caught me out several times when forgetting that ANY doesn’t work with lists.

If you want the MIME type for a file, you can use the following code:

- (NSString *)mimeTypeForPath:(NSString *)path
{
    // get a mime type for an extension using MobileCoreServices.framework

    CFStringRef extension = (__bridge CFStringRef)[path pathExtension];
    CFStringRef UTI = UTTypeCreatePreferredIdentifierForTag(kUTTagClassFilenameExtension, extension, NULL);
    assert(UTI != NULL);

    NSString *mimetype = CFBridgingRelease(UTTypeCopyPreferredTagWithClass(UTI, kUTTagClassMIMEType));
    assert(mimetype != NULL);

    CFRelease(UTI);

    return mimetype;
}

In the case of a ZIP file, this will return application/zip.

This is default by iOS7 design. try to do the below:

[tableView setSeparatorInset:UIEdgeInsetsMake(0, 0, 0, 0)];

You can set the 'Separator Inset' from the storyboard:

I do not like transformations to have any more info than needed. So instead of restating the keys, I simply state the condition and intention. It is much easier to see the intention when done like this, at least IMO. Also, I try and put all the xdt attributes first to indicate to the reader, these are transformations and not new things being defined.

<appSettings>
  <add xdt:Locator="Condition(@key='developmentModeUserId')" xdt:Transform="Remove" />
  <add xdt:Locator="Condition(@key='developmentMode')" xdt:Transform="SetAttributes"
       value="false"/>
</appSettings>

In the above it is much easier to see that the first one is removing the element. The 2nd one is setting attributes. It will set/replace any attributes you define here. In this case it will simply set value to false.

For dev work you can use (express 4) https://github.com/appsmatics/simple-httpserver.git

little complete sample:

using System.ComponentModel;

private bool bShowGroup ;
[Description("Show the group table"), Category("Sea"),DefaultValue(true)]
public bool ShowGroup
{
    get { return bShowGroup; }
    set { bShowGroup = value; }
}

List is just an interface. The question is: is your actual List implementation serializable? Speaking about the standard List implementations (ArrayList, LinkedList) from the Java run-time, most of them actually are already.

You don't need to iterate through the DataGrid rows, you can achieve your goal with a more simple solution. In order to match your row you can iterate through you collection that was bound to your DataGrid.ItemsSource property then assign this item to you DataGrid.SelectedItem property programmatically, alternatively you can add it to your DataGrid.SelectedItems collection if you want to allow the user to select more than one row. See the code below:

<Window x:Class="ProgGridSelection.MainWindow"
    xmlns="http://schemas.microsoft.com/winfx/2006/xaml/presentation"
    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"
    Title="MainWindow" Height="350" Width="525" Loaded="OnWindowLoaded">
<StackPanel>
    <DataGrid Name="empDataGrid" ItemsSource="{Binding}" Height="200"/>
    <TextBox Name="empNameTextBox"/>
    <Button Content="Click" Click="OnSelectionButtonClick" />
</StackPanel>

public partial class MainWindow : Window
{
    public class Employee
    {
        public string Code { get; set; }
        public string Name { get; set; }
    }

    private ObservableCollection<Employee> _empCollection;

    public MainWindow()
    {
        InitializeComponent();
    }

    private void OnWindowLoaded(object sender, RoutedEventArgs e)
    {
        // Generate test data
        _empCollection =
            new ObservableCollection<Employee>
                {
                    new Employee {Code = "E001", Name = "Mohammed A. Fadil"},
                    new Employee {Code = "E013", Name = "Ahmed Yousif"},
                    new Employee {Code = "E431", Name = "Jasmin Kamal"},
                };

        /* Set the Window.DataContext, alternatively you can set your
         * DataGrid DataContext property to the employees collection.
         * on the other hand, you you have to bind your DataGrid
         * DataContext property to the DataContext (see the XAML code)
         */
        DataContext = _empCollection;
    }

    private void OnSelectionButtonClick(object sender, RoutedEventArgs e)
    {
        /* select the employee that his name matches the
         * name on the TextBox
         */
        var emp = (from i in _empCollection
                   where i.Name == empNameTextBox.Text.Trim()
                   select i).FirstOrDefault();

        /* Now, to set the selected item on the DataGrid you just need
         * assign the matched employee to your DataGrid SeletedItem
         * property, alternatively you can add it to your DataGrid
         * SelectedItems collection if you want to allow the user
         * to select more than one row, e.g.:
         *    empDataGrid.SelectedItems.Add(emp);
         */
        if (emp != null)
            empDataGrid.SelectedItem = emp;
    }
}

The plus sign is the historic encoding for a space character in URL parameters, as documented in the help for the urlencode() function.

That same page contains the answer you need - use rawurlencode() instead to get RFC 3986 compatible encoding.

something like this ? :

DataTable dt = ...
DataView dv = new DataView(dt);
dv.RowFilter = "(EmpName != 'abc' or EmpName != 'xyz') and (EmpID = 5)"

Is it what you are searching for?

You can pass a numpy array or matrix as an argument when initializing a sparse matrix. For a CSR matrix, for example, you can do the following.

>>> import numpy as np
>>> from scipy import sparse
>>> A = np.array([[1,2,0],[0,0,3],[1,0,4]])
>>> B = np.matrix([[1,2,0],[0,0,3],[1,0,4]])

>>> A
array([[1, 2, 0],
       [0, 0, 3],
       [1, 0, 4]])

>>> sA = sparse.csr_matrix(A)   # Here's the initialization of the sparse matrix.
>>> sB = sparse.csr_matrix(B)

>>> sA
<3x3 sparse matrix of type '<type 'numpy.int32'>'
        with 5 stored elements in Compressed Sparse Row format>

>>> print sA
  (0, 0)        1
  (0, 1)        2
  (1, 2)        3
  (2, 0)        1
  (2, 2)        4

You could try this:

 $(".edgetoedge").children().removeClass("highlight");

In mysql the SET clause needs to come after the JOIN. Example:

UPDATE e
    LEFT JOIN a ON a.id = e.aid
    SET e.id = 2
    WHERE  
        e.type = 'user' AND
        a.country = 'US';

I got a similar prompt. It was because I had specified the x-axis in terms of some percentage (for example: 10%A, 20%B,....). So an alternate approach could be that you multiply these values and write them in the simplest form.

I'm a big fan of hdf5 for storing large numpy arrays. There are two options for dealing with hdf5 in python:

http://www.pytables.org/

http://www.h5py.org/

Both are designed to work with numpy arrays efficiently.

<style>
a {
color:      ;
}
</style>

This code changes the color from the default to what is specified in the style. Using a:hover, you can change the color of the text from the default on hover.

Best solution for expand/collapse view's:

    @Override
    public void onCheckedChanged(CompoundButton buttonView, boolean isChecked) {
        View view = buttonView.getId() == R.id.tb_search ? fSearch : layoutSettings;
        transform(view, 200, isChecked
            ? ViewGroup.LayoutParams.WRAP_CONTENT
            : 0);
    }

    public static void transform(final View v, int duration, int targetHeight) {
        int prevHeight  = v.getHeight();
        v.setVisibility(View.VISIBLE);
        ValueAnimator animator;
        if (targetHeight == ViewGroup.LayoutParams.WRAP_CONTENT) {
            v.measure(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.WRAP_CONTENT);
            animator = ValueAnimator.ofInt(prevHeight, v.getMeasuredHeight());
        } else {
            animator = ValueAnimator.ofInt(prevHeight, targetHeight);
        }
        animator.addUpdateListener(animation -> {
            v.getLayoutParams().height = (animation.getAnimatedFraction() == 1.0f)
                    ? targetHeight
                    : (int) animation.getAnimatedValue();
            v.requestLayout();
        });
        animator.setInterpolator(new LinearInterpolator());
        animator.setDuration(duration);
        animator.start();
    }

You can reverse by the $index parameter

• The code 302 indicates a temporary redirection.
• One of the most notable features that differentiate it from a 301 redirect is that, in the case of 302 redirects, the strength of the SEO is not transferred to a new URL.
• This is because this redirection has been designed to be used when there is a need to redirect content to a page that will not be the definitive one. Thus, once the redirection is eliminated, the original page will not have lost its positioning in the Google search engine.

EXAMPLE:- Although it is not very common that we find ourselves in need of a 302 redirect, this option can be very useful in some cases. These are the most frequent cases:

• When we realize that there is some inappropriate content on a page. While we solve the problem, we can redirect the user to another page that may be of interest.
• In the event that an attack on our website requires the restoration of any of the pages, this redirect can help us minimize the incidence.

A redirect 302 is a code that tells visitors of a specific URL that the page has been moved temporarily, directing them directly to the new location.

• In other words, redirect 302 is activated when Google robots or other search engines request to load a specific page. At that moment, thanks to this redirection, the server returns an automatic response indicating a new URL.

• In this way errors and annoyances are avoided both to search engines and users, guaranteeing smooth navigation.

I thought it could be worthwhile to have a micro-benchmark comparing the run-times of the different approaches mentioned here.

Disclaimer: I'm using simple_benchmark (a library written by me) for the benchmarks and also include iteration_utilities.count_items (a function in a third-party-library written by me).

To provide a more differentiated result I've done two benchmarks, one only including the approaches that don't build an intermediate container just to throw it away and one including these:

from simple_benchmark import BenchmarkBuilder
import more_itertools as mi
import iteration_utilities as iu

b1 = BenchmarkBuilder()
b2 = BenchmarkBuilder()

@b1.add_function()
@b2.add_function()
def summation(it):
    return sum(1 for _ in it)

@b1.add_function()
def len_list(it):
    return len(list(it))

@b1.add_function()
def len_listcomp(it):
    return len([_ for _ in it])

@b1.add_function()
@b2.add_function()
def more_itertools_ilen(it):
    return mi.ilen(it)

@b1.add_function()
@b2.add_function()
def iteration_utilities_count_items(it):
    return iu.count_items(it)

@b1.add_arguments('length')
@b2.add_arguments('length')
def argument_provider():
    for exp in range(2, 18):
        size = 2**exp
        yield size, [0]*size

r1 = b1.run()
r2 = b2.run()

import matplotlib.pyplot as plt

f, (ax1, ax2) = plt.subplots(2, 1, sharex=True, figsize=[15, 18])
r1.plot(ax=ax2)
r2.plot(ax=ax1)
plt.savefig('result.png')

The results were:

It uses log-log-axis so that all ranges (small values, large values) can be inspected. Since the plots are intended for qualitative comparison the actual values aren't too interesting. In general the y-axis (vertical) represents the time and the x-axis (horizontal) represents the number of elements in the input "iterable". Lower on the vertical axis means faster.

The upper plot shows the approaches where no intermediate list was used. Which shows that the iteration_utilities approach was fastest, followed by more_itertools and the slowest was using sum(1 for _ in iterator).

The lower plot also included the approaches that used len() on an intermediate list, once with list and once with a list comprehension. The approach with len(list) was fastest here, but the difference to the iteration_utilities approach is almost negligible. The approach using the comprehension was significantly slower than using list directly.

Summary

Any approach mentioned here did show a dependency on the length of the input and iterated over ever element in the iterable. There is no way to get the length without the iteration (even if the iteration is hidden).

If you don't want third-party extensions then using len(list(iterable)) is definitely the fastest approach of the tested approaches, it however generates an intermediate list which could use significant more memory.

If you don't mind additional packages then iteration_utilities.count_items would be almost as fast as the len(list(...)) function but doesn't require additional memory.

However it's important to note that the micro-benchmark used a list as input. The result of the benchmark could be different depending on the iterable you want to get the length of. I also tested with range and a simple genertor-expression and the trends were very similar, however I cannot exclude that the timing won't change depending on the type of input.

int indexOf(Object o) This method returns the index in this list of the first occurrence of the specified element, or -1 if this list does not contain this element.

FIXED IT!

I was losing my mind over this one. Reset firefox, tried safe mode, removed plugins, debugged using developers tools. All were to no avail and didn't get me any further with getting my online videos back to normal viewing condition. This however did the trick perfectly.

Within Firefox or whatever flavor of Firefox you have(CyberFox being my favorite choice here), simply browse to https://get.adobe.com/flashplayer/

VERIFY FIRST that the website detected you're using FireFox and has set your download for the flash player to be for Firefox.

Don't just click download. PLEASE PLEASE PLEASE SAVE YOURSELF the migraine and ALWAYS make sure that the middle section labeled "Optional offer:" is absolutely NOT CHECKED, it will be checked by default so always UNCHECK it before proceeding to download.

After it's finished downloading, close out of Firefox. Run the downloaded setup file As Administrator. It takes only a few seconds or so to complete, so after it's done, open up Firefox again and try viewing anything that was previously throwing this error. Should be back to normal now.

Enjoy!

The <select> tag creates a dropdown list. You can't put html links inside a dropdown.

However, there are JavaScript libraries that provide similar functionality. Here is one example: http://www.dynamicdrive.com/dynamicindex1/dropmenuindex.htm

If you are trying to return the time like a stopwatch you could use the following API which returns the time in milliseconds since system startup:

Public Declare Function GetTickCount Lib "kernel32.dll" () As Long
Sub testTimer()
Dim t As Long
t = GetTickCount

For i = 1 To 1000000
a = a + 1
Next

MsgBox GetTickCount - t, , "Milliseconds"
End Sub

after http://www.pcreview.co.uk/forums/grab-time-milliseconds-included-vba-t994765.html (as timeGetTime in winmm.dll was not working for me and QueryPerformanceCounter was too complicated for the task needed)

Until React provides a better way, you can create a helper, useEffectAsync.js:

import { useEffect } from 'react';


export default function useEffectAsync(effect, inputs) {
    useEffect(() => {
        effect();
    }, inputs);
}

Now you can pass an async function:

useEffectAsync(async () => {
    const items = await fetchSomeItems();
    console.log(items);
}, []);

Update

If you choose this approach, note that it's bad form. I resort to this when I know it's safe, but it's always bad form and haphazard.

Suspense for Data Fetching, which is still experimental, will solve some of the cases.

In other cases, you can model the async results as events so that you can add or remove a listener based on the component life cycle.

Or you can model the async results as an Observable so that you can subscribe and unsubscribe based on the component life cycle.

Use this:

function AmexCardnumber(inputtxt) {
  var cardno = /^(?:3[47][0-9]{13})$/;
  return cardno.test(inputtxt);
}

function VisaCardnumber(inputtxt) {
  var cardno = /^(?:4[0-9]{12}(?:[0-9]{3})?)$/;
  return cardno.test(inputtxt);
}

function MasterCardnumber(inputtxt) {
  var cardno = /^(?:5[1-5][0-9]{14})$/;
  return cardno.test(inputtxt);
}

function DiscoverCardnumber(inputtxt) {
  var cardno = /^(?:6(?:011|5[0-9][0-9])[0-9]{12})$/;
  return cardno.test(inputtxt);
}

function DinerClubCardnumber(inputtxt) {
  var cardno = /^(?:3(?:0[0-5]|[68][0-9])[0-9]{11})$/;
  return cardno.test(inputtxt);
}

function JCBCardnumber(inputtxt) {
  var cardno = /^(?:(?:2131|1800|35\d{3})\d{11})$/;
  return cardno.test(inputtxt);
}

function IsValidCreditCardNumber(cardNumber) {

  var cardType = null;
  if (VisaCardnumber(cardNumber)) {
    cardType = "visa";
  } else if (MasterCardnumber(cardNumber)) {
    cardType = "mastercard";
  } else if (AmexCardnumber(cardNumber)) {
    cardType = "americanexpress";
  } else if (DiscoverCardnumber(cardNumber)) {
    cardType = "discover";
  } else if (DinerClubCardnumber(cardNumber)) {
    cardType = "dinerclub";
  } else if (JCBCardnumber(cardNumber)) {
    cardType = "jcb";
  }

  return cardType;
}

If just wanted to show math in the browser for yourself, you could try the Chrome extension GitHub with MathJax. It's quite convenient.

Definitely Method A because its pooled and thread safe.

If you are using httpclient 4.x, the connection manager is called ThreadSafeClientConnManager. See this link for further details (scroll down to "Pooling connection manager"). For example:

    HttpParams params = new BasicHttpParams();
    SchemeRegistry registry = new SchemeRegistry();
    registry.register(new Scheme("http", PlainSocketFactory.getSocketFactory(), 80));
    ClientConnectionManager cm = new ThreadSafeClientConnManager(params, registry);
    HttpClient client = new DefaultHttpClient(cm, params);

This is a very good question and sadly many developers don't ask enough questions about IIS/ASP.NET security in the context of being a web developer and setting up IIS. So here goes....

To cover the identities listed:

IIS_IUSRS:

This is analogous to the old IIS6 IIS_WPG group. It's a built-in group with it's security configured such that any member of this group can act as an application pool identity.

IUSR:

This account is analogous to the old IUSR_<MACHINE_NAME> local account that was the default anonymous user for IIS5 and IIS6 websites (i.e. the one configured via the Directory Security tab of a site's properties).

For more information about IIS_IUSRS and IUSR see:

Understanding Built-In User and Group Accounts in IIS 7

DefaultAppPool:

If an application pool is configured to run using the Application Pool Identity feature then a "synthesised" account called IIS AppPool\<pool name> will be created on the fly to used as the pool identity. In this case there will be a synthesised account called IIS AppPool\DefaultAppPool created for the life time of the pool. If you delete the pool then this account will no longer exist. When applying permissions to files and folders these must be added using IIS AppPool\<pool name>. You also won't see these pool accounts in your computers User Manager. See the following for more information:

Application Pool Identities

ASP.NET v4.0: -

This will be the Application Pool Identity for the ASP.NET v4.0 Application Pool. See DefaultAppPool above.

NETWORK SERVICE: -

The NETWORK SERVICE account is a built-in identity introduced on Windows 2003. NETWORK SERVICE is a low privileged account under which you can run your application pools and websites. A website running in a Windows 2003 pool can still impersonate the site's anonymous account (IUSR_ or whatever you configured as the anonymous identity).

In ASP.NET prior to Windows 2008 you could have ASP.NET execute requests under the Application Pool account (usually NETWORK SERVICE). Alternatively you could configure ASP.NET to impersonate the site's anonymous account via the <identity impersonate="true" /> setting in web.config file locally (if that setting is locked then it would need to be done by an admin in the machine.config file).

Setting <identity impersonate="true"> is common in shared hosting environments where shared application pools are used (in conjunction with partial trust settings to prevent unwinding of the impersonated account).

In IIS7.x/ASP.NET impersonation control is now configured via the Authentication configuration feature of a site. So you can configure to run as the pool identity, IUSR or a specific custom anonymous account.

LOCAL SERVICE:

The LOCAL SERVICE account is a built-in account used by the service control manager. It has a minimum set of privileges on the local computer. It has a fairly limited scope of use:

LocalService Account

LOCAL SYSTEM:

You didn't ask about this one but I'm adding for completeness. This is a local built-in account. It has fairly extensive privileges and trust. You should never configure a website or application pool to run under this identity.

LocalSystem Account

In Practice:

In practice the preferred approach to securing a website (if the site gets its own application pool - which is the default for a new site in IIS7's MMC) is to run under Application Pool Identity. This means setting the site's Identity in its Application Pool's Advanced Settings to Application Pool Identity:

In the website you should then configure the Authentication feature:

Right click and edit the Anonymous Authentication entry:

Ensure that "Application pool identity" is selected:

When you come to apply file and folder permissions you grant the Application Pool identity whatever rights are required. For example if you are granting the application pool identity for the ASP.NET v4.0 pool permissions then you can either do this via Explorer:

Click the "Check Names" button:

Or you can do this using the ICACLS.EXE utility:

icacls c:\wwwroot\mysite /grant "IIS AppPool\ASP.NET v4.0":(CI)(OI)(M)

...or...if you site's application pool is called BobsCatPicBlogthen:

icacls c:\wwwroot\mysite /grant "IIS AppPool\BobsCatPicBlog":(CI)(OI)(M)

I hope this helps clear things up.

Update:

I just bumped into this excellent answer from 2009 which contains a bunch of useful information, well worth a read:

The difference between the 'Local System' account and the 'Network Service' account?

Think of semaphores as bouncers at a nightclub. There are a dedicated number of people that are allowed in the club at once. If the club is full no one is allowed to enter, but as soon as one person leaves another person might enter.

It's simply a way to limit the number of consumers for a specific resource. For example, to limit the number of simultaneous calls to a database in an application.

Here is a very pedagogic example in C# :-)

using System;
using System.Collections.Generic;
using System.Text;
using System.Threading;

namespace TheNightclub
{
    public class Program
    {
        public static Semaphore Bouncer { get; set; }

        public static void Main(string[] args)
        {
            // Create the semaphore with 3 slots, where 3 are available.
            Bouncer = new Semaphore(3, 3);

            // Open the nightclub.
            OpenNightclub();
        }

        public static void OpenNightclub()
        {
            for (int i = 1; i <= 50; i++)
            {
                // Let each guest enter on an own thread.
                Thread thread = new Thread(new ParameterizedThreadStart(Guest));
                thread.Start(i);
            }
        }

        public static void Guest(object args)
        {
            // Wait to enter the nightclub (a semaphore to be released).
            Console.WriteLine("Guest {0} is waiting to entering nightclub.", args);
            Bouncer.WaitOne();          

            // Do some dancing.
            Console.WriteLine("Guest {0} is doing some dancing.", args);
            Thread.Sleep(500);

            // Let one guest out (release one semaphore).
            Console.WriteLine("Guest {0} is leaving the nightclub.", args);
            Bouncer.Release(1);
        }
    }
}

I had the same problem.

I had to print the color of the nodes where the color was: enum col { WHITE, GRAY, BLACK }; and the node: typedef struct Node { col color; };

I tried to print node->color with printf("%s\n", node->color); but all I got on the screen was (null)\n.

The answer bmargulies gave almost solved the problem.

So my final solution is:

static char *enumStrings[] = {"WHITE", "GRAY", "BLACK"};
printf("%s\n", enumStrings[node->color]);

Another approach to count number of list elements:

var num = $("#menu").find("li").length;_x000D_
if (num > 1) {_x000D_
  console.log(num);_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<ul id="menu">_x000D_
  <li>Element 1</li>_x000D_
  <li>Element 2</li>_x000D_
  <li>Element 3</li>_x000D_
</ul>

Easiest way would be to use join like this:

>>> myTuple = ['h','e','l','l','o']
>>> ''.join(myTuple)
'hello'

This works because your delimiter is essentially nothing, not even a blank space: ''.

Late joining the conversation. Based on:

https://codereview.stackexchange.com/a/179091/184415

There is indeed an O(n) complexity solution to this problem even if duplicate ints are involved in the input:

solution(A)
Filter out non-positive values from A
For each int in filtered
    Let a zero-based index be the absolute value of the int - 1
    If the filtered range can be accessed by that index  and  filtered[index] is not negative
        Make the value in filtered[index] negative

For each index in filtered
    if filtered[index] is positive
        return the index + 1 (to one-based)

If none of the elements in filtered is positive
    return the length of filtered + 1 (to one-based)

So an array A = [1, 2, 3, 5, 6], would have the following transformations:

abs(A[0]) = 1, to_0idx = 0, A[0] = 1, make_negative(A[0]), A = [-1,  2,  3,  5,  6]
abs(A[1]) = 2, to_0idx = 1, A[1] = 2, make_negative(A[1]), A = [-1, -2,  3,  5,  6]
abs(A[2]) = 3, to_0idx = 2, A[2] = 3, make_negative(A[2]), A = [-1, -2, -3,  5,  6]
abs(A[3]) = 5, to_0idx = 4, A[4] = 6, make_negative(A[4]), A = [-1, -2, -3,  5, -6]
abs(A[4]) = 6, to_0idx = 5, A[5] is inaccessible,          A = [-1, -2, -3,  5, -6]

A linear search for the first positive value returns an index of 3. Converting back to a one-based index results in solution(A)=3+1=4

Here's an implementation of the suggested algorithm in C# (should be trivial to convert it over to Java lingo - cut me some slack common):

public int solution(int[] A)
{
    var positivesOnlySet = A
        .Where(x => x > 0)
        .ToArray();

    if (!positivesOnlySet.Any())
        return 1;

    var totalCount = positivesOnlySet.Length;
    for (var i = 0; i < totalCount; i++) //O(n) complexity
    {
        var abs = Math.Abs(positivesOnlySet[i]) - 1;
        if (abs < totalCount && positivesOnlySet[abs] > 0) //notice the greater than zero check 
            positivesOnlySet[abs] = -positivesOnlySet[abs];
    }

    for (var i = 0; i < totalCount; i++) //O(n) complexity
    {
        if (positivesOnlySet[i] > 0)
            return i + 1;
    }

    return totalCount + 1;
}

I suggest to see the classic example at: http://maven.apache.org/guides/getting-started/index.html#How_do_I_build_more_than_one_project_at_once

Here my-webapp is web project, which depends on the code at my-app project. So to bundle two projects in one, we have top level pom.xml which mentions which are the projects (modules as per maven terminology) to be bundled finally. Such top level pom.xml can use pom packaging.

my-webapp can have war packaging and can have dependency on my-app. my-app can have jar packaging.

In virtual Box as said upper, you can add this line hosts file

10.0.2.2   outer

but to save it, if you don't have administrators right in your VM just move hosts file to desktop, then edit it to add the line 10.0....outer, save the file, and move to its original place.

Inspired by the idea from @MarSoft but I changed the lines like the following:

USERNAME='desireduser'
COMMAND=$0
COMMANDARGS="$(printf " %q" "${@}")"
if [ $(whoami) != "$USERNAME" ]; then
  exec sudo -E su $USERNAME -c "/usr/bin/bash -l $COMMAND $COMMANDARGS"
  exit
fi

I have used sudo to allow a password less execution of the script. If you want to enter a password for the user, remove the sudo. If you do not need the environment variables, remove -E from sudo.

The /usr/bin/bash -l ensures, that the profile.d scripts are executed for an initialized environment.

I have just tested Google Geocoder and got the same problem as you have. I noticed I only get the OVER_QUERY_LIMIT status once every 12 requests So I wait for 1 second (that's the minimum delay to wait) It slows down the application but less than waiting 1 second every request

info = getInfos(getLatLng(code)); //In here I call Google API
record(code, info);
generated++; 
if(generated%interval == 0) {
holdOn(delay); // Every x requests, I sleep for 1 second
}

With the basic holdOn method :

private void holdOn(long delay) {
        try {
            Thread.sleep(delay);
        } catch (InterruptedException ex) {
            // ignore
        }
    }

Hope it helps

I'm answering this question because I don't find any answer why the ^ don't work for powers. The ^ operator in C# is an exclusive or operator shorten as XOR. The truth table of A ^ B shows that it outputs true whenever the inputs differ:

Witch means that 100 ^ 3 does this calculation under the hood:

hex   binary
100 = 0110 0100 
  3 = 0000 0011
---   --------- ^
103 = 0110 0111

With is of course not the same as Math.Pow(100, 3) with results to one million. You can use that or one of the other existing answers.

You could also shorten your code to this that gives the same result because C# respects the order of operations.

double dimensions = 100 * 100 / Math.Pow(100, 3); // == 0.01

Since the hosts is blocked. try connect it from other host and execute the mysqladmin flush-hosts command.

mysqladmin -h <RDS ENDPOINT URL> -P <PORT> -u <USER> -p flush-hosts

Once you have Selected a group of sheets, you can use Selection

Consider:

Sub luxation()
    ThisWorkbook.Sheets(Array("Sheet1", "Sheet2", "Sheet3")).Select
    Selection.ExportAsFixedFormat _
        Type:=xlTypePDF, _
        Filename:="C:\TestFolder\temp.pdf", _
        Quality:=xlQualityStandard, _
        IncludeDocProperties:=True, _
        IgnorePrintAreas:=False, _
        OpenAfterPublish:=True
End Sub

EDIT#1:

Further testing has reveled that this technique depends on the group of cells selected on each worksheet. To get a comprehensive output, use something like:

Sub Macro1()

   Sheets("Sheet1").Activate
   ActiveSheet.UsedRange.Select
   Sheets("Sheet2").Activate
   ActiveSheet.UsedRange.Select
   Sheets("Sheet3").Activate
   ActiveSheet.UsedRange.Select

   ThisWorkbook.Sheets(Array("Sheet1", "Sheet2", "Sheet3")).Select
   Selection.ExportAsFixedFormat Type:=xlTypePDF, Filename:= _
      "C:\Users\James\Desktop\pdfmaker.pdf", Quality:=xlQualityStandard, _
      IncludeDocProperties:=True, IgnorePrintAreas:=False, OpenAfterPublish:= _
      True
End Sub

Comma-separated items enclosed by ( and ) are tuples, those enclosed by [ and ] are lists.

Although this question is 5 years old I have come across a nice solution.

Use the 'DictionaryEntry' object to pair keys and values.

Set the 'DisplayMember' and 'ValueMember' properties to:

   Me.myComboBox.DisplayMember = "Key"
   Me.myComboBox.ValueMember = "Value"

To add items to the ComboBox:

   Me.myComboBox.Items.Add(New DictionaryEntry("Text to be displayed", 1))

To retreive items like this:

MsgBox(Me.myComboBox.SelectedItem.Key & " " & Me.myComboBox.SelectedItem.Value)

It seems that since XCode 7.x a lot of warnings are coming out when enabling clang module with CLANG_ENABLE_MODULES

To create a new branch (locally):

• With the commit hash (or part of it)

  git checkout -b new_branch 6e559cb
  

• or to go back 4 commits from HEAD

  git checkout -b new_branch HEAD~4
  

Once your new branch is created (locally), you might want to replicate this change on a remote of the same name: How can I push my changes to a remote branch

For discarding the last three commits, see Lunaryorn's answer below.

For moving your current branch HEAD to the specified commit without creating a new branch, see Arpiagar's answer below.

Check your application.properties file. One of the probable reason for it is that

• you might be added "Spring Data" maven plugin and you are not providing the datastore details in application.properties file.

You do not need to use substring at all since your format doesn't hold that info.

SimpleDateFormat format = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss");
String fechaStr = "2013-10-10 10:49:29.10000";  
Date fechaNueva = format.parse(fechaStr);

System.out.println(format.format(fechaNueva)); // Prints 2013-10-10 10:49:29

I am using 0.56RC secureTextEntry={true} Along with password={true} then only its working as mentioned by @NicholasByDesign

Try to run gradle at the command line first. It might prompt you to setup and environment variable:

export _JAVA_OPTIONS="-Xms256m -Xmx1024m"

Further make sure that the Android SDK build tools (adb, aapt, dx, dx.jar) are available in the PATH. If not you can create symlinks at the appropriate locations. They changed with the release of new SDK versions. Here is a shell script which creates the symlinks within the $ANDROID_HOME folder for you.

Try

$ yum provides ld-linux.so.2
$ yum update
$ yum install glibc.i686 libfreetype.so.6 libfontconfig.so.1 libstdc++.so.6

Hope this clears out.

unfortunately we can't use in MySQL after INSERT or UPDATE description, like in Oracle

No, because that would open up the floodgates for phishing. The only part of the URI you can change is the fragment (everything after the #). You can do so by setting window.location.hash.

For those stuck with "The requested resource is not available" in Java EE 7 and dynamic web module 3.x, maybe this could help: the "Create Servlet" wizard in Eclipse (tested in Mars) doesn't create the @Path annotation for the servlet class, but I had to include it to access successfuly to the public methods exposed.

USING JAVA 8:

Map<String, String> headerMap = Arrays.stream(header.split(","))
                    .map(s -> s.split(":"))
                    .collect(Collectors.toMap(s -> s[0], s -> s[1]));

This is how you do it column-wise using list comprehension:

[df[col].update((df[col] - df[col].min()) / (df[col].max() - df[col].min())) for col in df.columns]

Here is my solution, gathered from different sources: Server side implementation :

    String contentType = MediaType.APPLICATION_OCTET_STREAM_VALUE;
    // Set headers
    response.setHeader("content-disposition", "attachment; filename =" + fileName);
    response.setContentType(contentType);
    // Copy file to output stream
    ServletOutputStream servletOutputStream = response.getOutputStream();
    try (InputStream inputStream = new FileInputStream(file)) {
        IOUtils.copy(inputStream, servletOutputStream);
    } finally {
        servletOutputStream.flush();
        Utils.closeQuitely(servletOutputStream);
        fileToDownload = null;
    }

Client side implementation (using jquery):

$.ajax({
type: 'POST',
contentType: 'application/json',
    url: <download file url>,
    data: JSON.stringify(postObject),
    error: function(XMLHttpRequest, textStatus, errorThrown) {
        alert(errorThrown);
    },
    success: function(message, textStatus, response) {
       var header = response.getResponseHeader('Content-Disposition');
       var fileName = header.split("=")[1];
       var blob = new Blob([message]);
       var link = document.createElement('a');
       link.href = window.URL.createObjectURL(blob);
       link.download = fileName;
       link.click();
    }
});   

If you need by several params:

$ids = [1,2,3,4];
$not_ids = [5,6,7,8];
DB::table('table')->whereIn('id', $ids)
                  ->whereNotIn('id', $not_ids)
                  ->where('status', 1)
                  ->get();

Use Observable pattern. You can put Observable value (not Subject) into Input parameter and manage it from parent component. You do not need callback function.

See example: https://stackoverflow.com/a/49662611/4604351

I've had a few cranberry-vodkas tonight so I might be missing something...Is setting the range necessary? Why not use:

Activeworkbook.Sheets("Game").Range("A1").value = "Subtotal"

Does this fail as well?

Looks like you tried something similar:

'Worksheets("Game").Range("A1") = "Asdf"

However, Worksheets is a collection, so you can't reference "Game". I think you need to use the Sheets object instead.

I just had fun with this issue for a couple of days and it was hard for me to find an answer for HTTPS, so here's my take, for Java:

    FirefoxProfile profile = new FirefoxProfile();
    profile.setPreference("network.proxy.type", 1);
    profile.setPreference("network.proxy.http", "proxy.domain.example.com");
    profile.setPreference("network.proxy.http_port", 8080);
    profile.setPreference("network.proxy.ssl", "proxy.domain.example.com");
    profile.setPreference("network.proxy.ssl_port", 8080);
    driver = new FirefoxDriver(profile);

Gotchas here: enter just the domain and not http://proxy.domain.example.com, the property name is .ssl and not .https

I'm now having even more fun trying to get it to accept my self signed certificates...

Why can't you just Create Multiple pictures for each part of the status bar? If it's a third just show a third of the status bar... it's very simple. You could probably figure out how to change it to the next picture based of input with the form tag. Here's my part of the code, you have to figure out the form stuff later

<form> <!--(extra code)-->
<!--first progress bar:-->
<img src="directory"></img>
<!--second progress bar:-->
<img src="directory"></img>
<!--et caetera...-->
</form>

Now it seems simple, doesn't it?

For me -D_GLIBCXX_USE_CXX11_ABI=0 didn't help.

You can easily use xml (from the Python standard library) to convert to a pandas.DataFrame. Here's what I would do (when reading from a file replace xml_data with the name of your file or file object):

import pandas as pd

        doc_dict['data'] = doc.text
        yield doc_dict

etree = ET.parse(xml_data) #create an ElementTree object 
doc_df = pd.DataFrame(list(iter_docs(etree.getroot())))

If there are multiple authors in your original document or the root of your XML is not an author, then I would add the following generator:

def iter_author(etree):
    for author in etree.iter('author'):
        for row in iter_docs(author):
            yield row

and change doc_df = pd.DataFrame(list(iter_docs(etree.getroot()))) to doc_df = pd.DataFrame(list(iter_author(etree)))

Have a look at the ElementTree tutorial provided in the xml library documentation.

Hope the following piece of code works for you:

def item = hudson.model.Hudson.instance.getItem('MyJob')

def value = item.lastBuild.getEnvironment(null).get('foo')

currentDay = new Date(currentDay).add(Date.DAY, +1).format('Y-m-d');

Comparision:

if (userProfile.AccountType == AccountType.Retailer)
{
    //your code
}

In case to prevent the NullPointerException you could add the following condition before comparing the AccountType:

if(userProfile != null)
{
    if (userProfile.AccountType == AccountType.Retailer)
    {
       //your code
    }
}

or shorter version:

if (userProfile !=null && userProfile.AccountType == AccountType.Retailer)
{
    //your code
}

You should set responseType: ResponseContentType.Blob in your GET-Request settings, because so you can get your image as blob and convert it later da base64-encoded source. You code above is not good. If you would like to do this correctly, then create separate service to get images from API. Beacuse it ism't good to call HTTP-Request in components.

Here is an working example:

Create image.service.ts and put following code:

Angular 4:

getImage(imageUrl: string): Observable<File> {
    return this.http
        .get(imageUrl, { responseType: ResponseContentType.Blob })
        .map((res: Response) => res.blob());
}

Angular 5+:

getImage(imageUrl: string): Observable<Blob> {
  return this.httpClient.get(imageUrl, { responseType: 'blob' });
}

Important: Since Angular 5+ you should use the new HttpClient.

The new HttpClient returns JSON by default. If you need other response type, so you can specify that by setting responseType: 'blob'. Read more about that here.

Now you need to create some function in your image.component.ts to get image and show it in html.

For creating an image from Blob you need to use JavaScript's FileReader. Here is function which creates new FileReader and listen to FileReader's load-Event. As result this function returns base64-encoded image, which you can use in img src-attribute:

imageToShow: any;

createImageFromBlob(image: Blob) {
   let reader = new FileReader();
   reader.addEventListener("load", () => {
      this.imageToShow = reader.result;
   }, false);

   if (image) {
      reader.readAsDataURL(image);
   }
}

Now you should use your created ImageService to get image from api. You should to subscribe to data and give this data to createImageFromBlob-function. Here is an example function:

getImageFromService() {
      this.isImageLoading = true;
      this.imageService.getImage(yourImageUrl).subscribe(data => {
        this.createImageFromBlob(data);
        this.isImageLoading = false;
      }, error => {
        this.isImageLoading = false;
        console.log(error);
      });
}

Now you can use your imageToShow-variable in HTML template like this:

<img [src]="imageToShow"
     alt="Place image title"
     *ngIf="!isImageLoading; else noImageFound">
<ng-template #noImageFound>
     <img src="fallbackImage.png" alt="Fallbackimage">
</ng-template>

I hope this description is clear to understand and you can use it in your project.

See the working example for Angular 5+ here.

Your CSV file might have variable number of columns and read_csv inferred the number of columns from the first few rows. Two ways to solve it in this case:

1) Change the CSV file to have a dummy first line with max number of columns (and specify header=[0])

2) Or use names = list(range(0,N)) where N is the max number of columns.

/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/jsp-api-6.0.16.jar
/var/lib/tomcat5.5/webapps/spaghetti/WEB-INF/lib/servlet-api-6.0.16.jar

You should not have any server-specific libraries in the /WEB-INF/lib. Leave them in the appserver's own library. It would only lead to collisions in the classpath. Get rid of all appserver-specific libraries in /WEB-INF/lib (and also in JRE/lib and JRE/lib/ext if you have placed any of them there).

A common cause that the appserver-specific libraries are included in the webapp's library is that starters think that it is the right way to fix compilation errors of among others the javax.servlet classes not being resolveable. Putting them in webapp's library is the wrong solution. You should reference them in the classpath during compilation, i.e. javac -cp /path/to/server/lib/servlet.jar and so on, or if you're using an IDE, you should integrate the server in the IDE and associate the web project with the server. The IDE will then automatically take server-specific libraries in the classpath (buildpath) of the webapp project.

<a href="javascript:void(0)" class="aaf" id="users_id">add as a friend</a>

on jquery

$('.aaf').on("click",function(){
  var usersid =  $(this).attr("id");
  //post code
})

//other method is to use the data attribute

<a href="javascript:void(0)" class="aaf" data-id="102" data-username="sample_username">add as a friend</a>

on jquery

$('.aaf').on("click",function(){
    var usersid =  $(this).data("id");
    var username = $(this).data("username");
})

0123456789 is not a valid integer (usually zeros will be stripped)

I think something like this regexp would be better to use:

^[1-9]([0-9]*)$

(does not support signed numbers)

You're looking at this wrong. Yes a linear search of a List will beat a HashSet for a small number of items. But the performance difference usually doesn't matter for collections that small. It's generally the large collections you have to worry about, and that's where you think in terms of Big-O. However, if you've measured a real bottleneck on HashSet performance, then you can try to create a hybrid List/HashSet, but you'll do that by conducting lots of empirical performance tests - not asking questions on SO.

If you have a PEM file (e.g. server.pem) containing:

• the trusted certificate
• the private key

then you can import the certificate and key into a JKS keystore like this:

1) Copy the private key from the PEM file into an ascii file (e.g. server.key)

2) Copy the cert from the PEM file into an ascii file (e.g. server.crt)

3) Export the cert and key into a PKCS12 file:

$ openssl pkcs12 -export -in server.crt -inkey server.key \
                 -out server.p12 -name [some-alias] -CAfile server.pem -caname root

• the PEM file can be used as the argument to the -CAfile option.
• you are prompted for an 'export' password.
• if doing this in git bash then add winpty to the start of the command so the export password can be entered.

4) Convert the PKCS12 file to a JKS keystore:

$ keytool -importkeystore -deststorepass changeit -destkeypass changeit \
          -destkeystore keystore.jks  -srckeystore server.p12 -srcstoretype PKCS12 \
          -srcstorepass changeit

• the srcstorepass password should match the export password from step 3)

Update for .NET Core 3.0+

1. You can use CreateDefaultBuilder which will automatically build and pass a configuration object to your startup class:

   WebHost.CreateDefaultBuilder(args).UseStartup<Startup>();
   

   public class Startup
   {
       public Startup(IConfiguration configuration) // automatically injected
       {
           Configuration = configuration;
       }
       public IConfiguration Configuration { get; }
       /* ... */
   }
   

2. CreateDefaultBuilder automatically includes the appropriate appsettings.Environment.json file so add a separate appsettings file for each environment:

   

3. Then set the ASPNETCORE_ENVIRONMENT environment variable when running / debugging

How to set Environment Variables

Depending on your IDE, there are a couple places dotnet projects traditionally look for environment variables:

• For Visual Studio go to Project > Properties > Debug > Environment Variables:

  

• For Visual Studio Code, edit .vscode/launch.json > env:

  

• Using Launch Settings, edit Properties/launchSettings.json > environmentVariables:

  

  Which can also be selected from the Toolbar in Visual Studio

  

• Using dotnet CLI, use the appropriate syntax for setting environment variables per your OS

  Note: When an app is launched with dotnet run, launchSettings.json is read if available, and environmentVariables settings in launchSettings.json override environment variables.

How does Host.CreateDefaultBuilder work?

.NET Core 3.0 added Host.CreateDefaultBuilder under platform extensions which will provide a default initialization of IConfiguration which provides default configuration for the app in the following order:

1. appsettings.json using the JSON configuration provider.
2. appsettings.Environment.json using the JSON configuration provider. For example:
   • appsettings.Production.json or
   • appsettings.Development.json
3. App secrets when the app runs in the Development environment.
4. Environment variables using the Environment Variables configuration provider.
5. Command-line arguments using the Command-line configuration provider.

There's a property that enables/disables in line media playback in the iOS web browser (if you were writing a native app, it would be the allowsInlineMediaPlayback property of a UIWebView). By default on iPhone this is set to NO, but on iPad it's set to YES.

Fortunately for you, you can also adjust this behaviour in HTML as follows:

<video id="myVideo" width="280" height="140" webkit-playsinline>

...that should hopefully sort it out for you. I don't know if it will work on your Android devices. It's a webkit property, so it might. Worth a go, anyway.

I have faced same issue, it may be issue of administrator, so followed below steps to setup docker on

windows10

.

1. Download docker desktop from docker hub after login to docker.Docker Desktop Installer.exe file will be downloaded.
2. Install Docker Desktop Installer.exeusing Run as administrator -> Mark windows container during installation else it will only install linux container. It will ask for Logout after logging out and login it shows docker desktop in menu.
3. After install, go to -> computer management -> Local users and groups -> Groups -> docker-user -> Add user in members
4. Run docker desktop using Run as administrator
5. Check docker whale icon in Notification tab
6. run command >docker version Successfully using docker without any issue.

So none of the above stuff worked for me. Except this: edit httpd.conf,

find the line

Listen 80 

and change to

listen 0.0.0.0:80 

if you are running windows 8, its got something to do with using ipv6 instead of ipv4

The only reliable way I've found that doesn't require plugging the phone in to a PC is as follows:

1. Force stop the Chrome app.

This must be done first, and you cannot re-open Chrome until you finish these steps. There are several ways to force stop. Most home launchers will let you get to "App info" by holding down your finger on the chrome icon and selecting an "i" icon. Alternately, you may be able to go to Android settings and simply search for "Chrome".

Once in "App info", select "Force stop" as shown below:

2. Clear Chrome's cache

Select "Storage" from the same screen:

Finally, select "Clear cache".

When you return to the Chrome app, the page should reload itself and serve a non-cached version.

Additionally, I found a site that makes it easy to test if you've cleared your cache: https://refreshyourcache.com/en/cache-test/
I am in no way affiliated with it. Note that the method to clear the cache mentioned on that site is in fact outdated and no longer valid.

What about LineSentence module, it will ignore such lines:

Bases: object

Simple format: one sentence = one line; words already preprocessed and separated by whitespace.

source can be either a string or a file object. Clip the file to the first limit lines (or not clipped if limit is None, the default).

from gensim.models.word2vec import LineSentence
text = LineSentence('text.txt')

Its happened with me. I deletes some css files by mistake and then copied back. This error appeared at that time. So i restart all my dockers and other servers and then it went away, Perhaps this help some one :)

You can use plain javascript, this will call your_func once, after 5 seconds:

setTimeout(function() { your_func(); }, 5000);

If your function has no parameters and no explicit receiver you can call directly setTimeout(func, 5000)

There is also a plugin I've used once. It has oneTime and everyTime methods.

• jQuery timers plugin

If you had caught the error, you would have seen this:

jsonString, err := json.Marshal(datas)
fmt.Println(err)

// [] json: unsupported type: map[int]main.Foo

The thing is you cannot use integers as keys in JSON; it is forbidden. Instead, you can convert these values to strings beforehand, for instance using strconv.Itoa.

A very simple approach for the dev who just want to send POST parameters in multipart request.

Make the following changes in class which extends Request.java

First define these constants :

String BOUNDARY = "s2retfgsGSRFsERFGHfgdfgw734yhFHW567TYHSrf4yarg"; //This the boundary which is used by the server to split the post parameters.
String MULTIPART_FORMDATA = "multipart/form-data;boundary=" + BOUNDARY;

Add a helper function to create a post body for you :

private String createPostBody(Map<String, String> params) {
        StringBuilder sbPost = new StringBuilder();
        if (params != null) {
            for (String key : params.keySet()) {
                if (params.get(key) != null) {
                    sbPost.append("\r\n" + "--" + BOUNDARY + "\r\n");
                    sbPost.append("Content-Disposition: form-data; name=\"" + key + "\"" + "\r\n\r\n");
                    sbPost.append(params.get(key).toString());
                }
            }
        }
        return sbPost.toString();
    } 

Override getBody() and getBodyContentType

public String getBodyContentType() {
    return MULTIPART_FORMDATA;
}

public byte[] getBody() throws AuthFailureError {
        return createPostBody(getParams()).getBytes();
}

I found this quite useful in my case after the button click.

$('#buttonId').blur();

I wanted to post an answer that there is a case where the variable won't be found.

Cyclical imports may break the module behavior.

For example:

first.py

On this is example it should be obvious, but in a large code-base, this can be really confusing.

Use the SC (service control) command, it gives you a lot more options than just start & stop.

  DESCRIPTION:
          SC is a command line program used for communicating with the
          NT Service Controller and services.
  USAGE:
      sc <server> [command] [service name]  ...

      The option <server> has the form "\\ServerName"
      Further help on commands can be obtained by typing: "sc [command]"
      Commands:
        query-----------Queries the status for a service, or
                        enumerates the status for types of services.
        queryex---------Queries the extended status for a service, or
                        enumerates the status for types of services.
        start-----------Starts a service.
        pause-----------Sends a PAUSE control request to a service.
        interrogate-----Sends an INTERROGATE control request to a service.
        continue--------Sends a CONTINUE control request to a service.
        stop------------Sends a STOP request to a service.
        config----------Changes the configuration of a service (persistant).
        description-----Changes the description of a service.
        failure---------Changes the actions taken by a service upon failure.
        qc--------------Queries the configuration information for a service.
        qdescription----Queries the description for a service.
        qfailure--------Queries the actions taken by a service upon failure.
        delete----------Deletes a service (from the registry).
        create----------Creates a service. (adds it to the registry).
        control---------Sends a control to a service.
        sdshow----------Displays a service's security descriptor.
        sdset-----------Sets a service's security descriptor.
        GetDisplayName--Gets the DisplayName for a service.
        GetKeyName------Gets the ServiceKeyName for a service.
        EnumDepend------Enumerates Service Dependencies.

      The following commands don't require a service name:
      sc <server> <command> <option>
        boot------------(ok | bad) Indicates whether the last boot should
                        be saved as the last-known-good boot configuration
        Lock------------Locks the Service Database
        QueryLock-------Queries the LockStatus for the SCManager Database
  EXAMPLE:
          sc start MyService

Inspired by the answers above, especially by Sagar Gala, I've created this API. You may use it if you don't want or can't upgrade your jquery version.

It's better to use an Iterator when you want to remove element from a list

because the source code of remove is

if (numMoved > 0)
    System.arraycopy(elementData, index+1, elementData, index,
             numMoved);
elementData[--size] = null;

so ,if you remove an element from the list, the list will be restructure ,the other element's index will be changed, this can result something that you want to happened.

An alternative using envsubst without losing the ability to use commands like COPY or ADD, and without using intermediate files would be to use Bash's Process Substitution:

docker build -f <(envsubst < Dockerfile) -t my-target .

Use textcleaner library to remove stopwords from your data.

Follow this link:https://yugantm.github.io/textcleaner/documentation.html#remove_stpwrds

Follow these steps to do so with this library.

pip install textcleaner

After installing:

import textcleaner as tc
data = tc.document(<file_name>) 
#you can also pass list of sentences to the document class constructor.
data.remove_stpwrds() #inplace is set to False by default

Use above code to remove the stop-words.

suppose the multiSelect is the Multiple-Select-Element, just use its selectedOptions Property:

//show all selected options in the console:

for ( var i = 0; i < multiSelect.selectedOptions.length; i++) {
  console.log( multiSelect.selectedOptions[i].value);
}

I think you have put command like java -VERSION. This is in capital letters You need to put all command in lowercase letters

javac -version
java -version

All characters must be in lowercase letter

Try this:

    int lowIndex = 0;
    int highIndex = elements.length-1;

    while(lowIndex < highIndex) {
        T lowVal = elements[lowIndex];
        T highVal = elements[highIndex];
        elements[lowIndex] = highVal;
        elements[highIndex] = lowVal;

        lowIndex += 1;
        highIndex -=1;
    }

In my case it was because I was using a port other than the default port 80. I was able to access the site locally using localhost but not on another machine using the IP address.

To solve the issue I had to add a firewall inbound rule to allow the port.

In Parcelable, developers write custom code for marshalling and unmarshalling so it creates fewer garbage objects in comparison to Serialization. The performance of Parcelable over Serialization dramatically improves (around two times faster), because of this custom implementation.

Serializable is a marker interface, which implies that user cannot marshal the data according to their requirements. In Serialization, a marshaling operation is performed on a Java Virtual Machine (JVM) using the Java reflection API. This helps identify the Java object's member and behavior, but also ends up creating a lot of garbage objects. Due to this, the Serialization process is slow in comparison to Parcelable.

Edit: What is the meaning of marshalling and unmarshalling?

In few words, "marshalling" refers to the process of converting the data or the objects into a byte-stream, and "unmarshalling" is the reverse process of converting the byte-stream back to their original data or object. The conversion is achieved through "serialization".

You can also get the WINDOW width and height, avoiding browser toolbars and other stuff. It is the real usable area in browser's window.

To do this, use: window.innerWidth and window.innerHeight properties (see doc at w3schools).

In most cases it will be the best way, in example, to display a perfectly centred floating modal dialog. It allows you to calculate positions on window, no matter which resolution orientation or window size is using the browser.

Create an XML file named border.xml in the drawable folder and put the following code in it.

 <?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
  <item> 
    <shape android:shape="rectangle">
      <solid android:color="#FF0000" /> 
    </shape>
  </item>   
    <item android:left="5dp" android:right="5dp"  android:top="5dp" >  
     <shape android:shape="rectangle"> 
      <solid android:color="#000000" />
    </shape>
   </item>    
 </layer-list> 

Then add a background to your linear layout like this:

         android:background="@drawable/border"

EDIT :

This XML was tested with a galaxy s running GingerBread 2.3.3 and ran perfectly as shown in image below:

ALSO

tested with galaxy s 3 running JellyBean 4.1.2 and ran perfectly as shown in image below :

Finally its works perfectly with all APIs

EDIT 2 :

It can also be done using a stroke to keep the background as transparent while still keeping a border except at the bottom with the following code.

<?xml version="1.0" encoding="utf-8"?>
 <layer-list xmlns:android="http://schemas.android.com/apk/res/android">
   <item android:left="0dp" android:right="0dp"  android:top="0dp"  
        android:bottom="-10dp"> 
    <shape android:shape="rectangle">
     <stroke android:width="10dp" android:color="#B22222" />
    </shape>
   </item>  
 </layer-list> 

hope this help .

Try this awesome ink-html library

import print from 'ink-html'
// const print = require('ink-html').default

// js
print(window.querySelector('#printable'))
// Vue.js
print(this.$refs.printable.$el)

I think this solution is short and seem looks nice:

long long fib(int n){
  return n<=2?1:fib(n-1)+fib(n-2);
}

Edit : as jweyrich mentioned, true recursive function should be:

long long fib(int n){
      return n<2?n:fib(n-1)+fib(n-2);
    }

(because fib(0) = 0. but base on above recursive formula, fib(0) will be 1)

To understand recursion algorithm, you should draw to your paper, and the most important thing is : "Think normal as often".

Also try changing from this:

    SELECT * FROM table WHERE Contains(Column, "test") > 0;

To this:

    SELECT * FROM table WHERE Contains(Column, '"*test*"') > 0;

The former will find records with values like "this is a test" and "a test-case is the plan".

The latter will also find records with values like "i am testing this" and "this is the greatest".

I have stopped using ORMs.

The reason is not any great flaw in the concept. Hibernate works well. Instead, I have found that queries have low overhead and I can fit lots of complex logic into large SQL queries, and shift a lot of my processing into the database.

So consider just using the JDBC package.

If you have your drawable set to the ImageView you can do it with a 1 liner:

yourImageView.setColorFilter(context.getResources().getColor(R.color.YOUR_COLOR_HERE);

Few hints to handle such error/exception for Android Apps:

1. Activities & Application have methods like:

   • onLowMemory
   • onTrimMemory Handle these methods to watch on memory usage.

2. tag in Manifest can have attribute 'largeHeap' set to TRUE, which requests more heap for App sandbox.

3. Managing in-memory caching & disk caching:

   • Images and other data could have been cached in-memory while app running, (locally in activities/fragment and globally); should be managed or removed.

4. Use of WeakReference, SoftReference of Java instance creation , specifically to files.

5. If so many images, use proper library/data structure which can manage memory, use samling of images loaded, handle disk-caching.

6. Handle OutOfMemory exception

7. Follow best practices for coding

   • Leaking of memory (Don't hold everything with strong reference)

8. Minimize activity stack e.g. number of activities in stack (Don't hold everything on context/activty)

   • Context makes sense, those data/instances not required out of scope (activity and fragments), hold them into appropriate context instead global reference-holding.

9. Minimize the use of statics, many more singletons.

10. Take care of OS basic memory fundametals

    • Memory fragmentation issues

11. Involk GC.Collect() manually sometimes when you are sure that in-memory caching no more needed.

You would need to do something like this. I am typing this off the top of my head, so this may not be 100% correct.

CGColorSpaceRef colorSpace = CGColorSpaceCreateDeviceRGB(); CGContextRef context = CGBitmapContextCreate(NULL, 640, 360, 8, 4 * width, colorSpace, kCGImageAlphaPremultipliedFirst); CGColorSpaceRelease(colorSpace);  CGContextDrawImage(context, CGRectMake(0,-160,640,360), cgImgFromAVCaptureSession);  CGImageRef image = CGBitmapContextCreateImage(context); UIImage* myCroppedImg = [UIImage imageWithCGImage:image]; CGContextRelease(context);       

This might not be relevant to your specific problem, but the error message you mentioned has many causes, one of them is using a return type for an [OperationContract] that is either abstract, interface, or not known to the WCF client code.

Angular 2 Beta

This answer is for those who use Javascript for angularJS v.2.0 Beta.

To use ngModel in your view you should tell the angular's compiler that you are using a directive called ngModel.

How?

To use ngModel there are two libraries in angular2 Beta, and they are ng.common.FORM_DIRECTIVES and ng.common.NgModel.

Actually ng.common.FORM_DIRECTIVES is nothing but group of directives which are useful when you are creating a form. It includes NgModel directive also.

app.myApp = ng.core.Component({
    selector: 'my-app',
    templateUrl: 'App/Pages/myApp.html',
    directives: [ng.common.NgModel] // specify all your directives here
}).Class({
    constructor: function () {
        this.myVar = {};
        this.myVar.text = "Testing";
    },

});

In the navigator under SCHEMAS, right click your schema/database and select "Table Data Import Wizard"

Works for mac too.

With "Asset Type" set to "Image", try setting the same image for the foreground and background layers, keeping the same "Resize" percentage.

Well, first you need to request the username of the user from the session in your controller action like this:

$username=$this->get('security.context')->getToken()->getUser()->getUserName();

then do a query to the db and get your object with regular dql like

$em = $this->get('doctrine.orm.entity_manager');    
"SELECT u FROM Acme\AuctionBundle\Entity\User u where u.username=".$username;
$q=$em->createQuery($query);
$user=$q->getResult();

the $user should now hold the user with this username ( you could also use other fields of course)

...but you will have to first configure your /app/config/security.yml configuration to use the appropriate field for your security provider like so:

security:
 provider:
  example:
   entity: {class Acme\AuctionBundle\Entity\User, property: username}

hope this helps!

You can use twiny to create 2 x-axis scales. For Example:

import numpy as np
import matplotlib.pyplot as plt

fig = plt.figure()
ax1 = fig.add_subplot(111)
ax2 = ax1.twiny()

a = np.cos(2*np.pi*np.linspace(0, 1, 60.))

ax1.plot(range(60), a)
ax2.plot(range(100), np.ones(100)) # Create a dummy plot
ax2.cla()
plt.show()

Ref: http://matplotlib.sourceforge.net/faq/howto_faq.html#multiple-y-axis-scales

Output:

A packet is a general term for a formatted unit of data carried by a network. It is not necessarily connected to a specific OSI model layer.

For example, in the Ethernet protocol on the physical layer (layer 1), the unit of data is called an "Ethernet packet", which has an Ethernet frame (layer 2) as its payload. But the unit of data of the Network layer (layer 3) is also called a "packet".

A frame is also a unit of data transmission. In computer networking the term is only used in the context of the Data link layer (layer 2).

Another semantical difference between packet and frame is that a frame envelops your payload with a header and a trailer, just like a painting in a frame, while a packet usually only has a header.

But in the end they mean roughly the same thing and the distinction is used to avoid confusion and repetition when talking about the different layers.

You can directly plot the lines you want by feeding the plot command with the corresponding data (boundaries of the segments):

plot([x1, x2], [y1, y2], color='k', linestyle='-', linewidth=2)

(of course you can choose the color, line width, line style, etc.)

From your example:

import numpy as np
import matplotlib.pyplot as plt

np.random.seed(5)
x = np.arange(1, 101)
y = 20 + 3 * x + np.random.normal(0, 60, 100)
plt.plot(x, y, "o")


# draw vertical line from (70,100) to (70, 250)
plt.plot([70, 70], [100, 250], 'k-', lw=2)

# draw diagonal line from (70, 90) to (90, 200)
plt.plot([70, 90], [90, 200], 'k-')

plt.show()

Series is a one-dimensional object that can hold any data type such as integers, floats and strings e.g

   import pandas as pd
   x = pd.Series([A,B,C]) 

0 A
1 B
2 C

The first column of Series is known as index i.e 0,1,2 the second column is your actual data i.e A,B,C

DataFrames is two-dimensional object that can hold series, list, dictionary

df=pd.DataFrame(rd(5,4),['A','B','C','D','E'],['W','X','Y','Z'])

To treat validation when a field is null in the database, you could add the following condition.

String name = (oRs.getString ("name_column"))! = Null? oRs.getString ("name_column"): "";

with this you can validate when a field is null and do not mark an exception.

__FILE__ is the filename with extension of the file containing the code being executed.

In foo.rb, __FILE__ would be "foo.rb".

If foo.rb were in the dir /home/josh then File.dirname(__FILE__) would return /home/josh.

getSupportActionBar().setDisplayShowHomeEnabled(true);
getSupportActionBar().setIcon(R.drawable.ic_launcher);

OR make a XML layout call the tool_bar.xml

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.Toolbar xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    android:background="@color/colorPrimary"
    android:theme="@style/ThemeOverlay.AppCompat.Dark"
    android:elevation="4dp">

    <RelativeLayout
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:orientation="horizontal">

    <ImageButton
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:background="@color/colorPrimary"
        android:src="@drawable/ic_action_search"/>

    </RelativeLayout>
</android.support.v7.widget.Toolbar>

Now in you main activity add this line

 <include
     android:id="@+id/tool_bar"
     layout="@layout/tool_bar" />

Aggregating with $lookup and subsequent $group is pretty cumbersome, so if (and that's a medium if) you're using node & Mongoose or a supporting library with some hints in the schema, you could use a .populate() to fetch those documents:

var mongoose = require("mongoose"),
    Schema = mongoose.Schema;

var productSchema = Schema({ ... });

var orderSchema = Schema({
  _id     : Number,
  products: [ { type: Schema.Types.ObjectId, ref: "Product" } ]
});

var Product = mongoose.model("Product", productSchema);
var Order   = mongoose.model("Order", orderSchema);

...

Order
    .find(...)
    .populate("products")
    ...

You have to just check whether your WAMP server is online or not.

To put your WAMP server online, follow these steps.

1. Go to your WAMP server notification icon (in the task bar).
2. Single click on the WAMP server icon.
3. Select last option from the menu, that is, Put Online
4. Your server will restart automatically (in the latest versions only). Otherwise, you have to restart your server manually.

And you are DONE...

you must be using old version of wget i had same issue. i was using wget 1.12.so to solve this issue there are 2 way: Update wget or use curl

curl -LO 'https://example.com/filename.tar.gz'

I probably tried all the solutions mentioned above but all in vain. To summarize, I did:

• I enable the virtualization going to BIOS setting.

• Uncheck Hyper-V option by going to Turn Windows features on or off.

• Download HAXM directly from the website https://software.intel.com/en-us/android/articles/intel-hardware-accelerated-execution-manager and install it.

• Uninstall and reinstall Android Studio.

• Copy the HAXM from my another system where HAXM was working fine, from the location C:\Users\UserName\AppData\Local\Android\Sdk\extras\intel

Nothing worked for me. What worked for me: I noticed the issue "unable to run mksdcard sdk tool" when I try to download SDK platform.So after some research, I found some SDK tools such as mksdcard.exe require Microsoft Visual C++ runtime 2015-2019. So based on my system type,(for me it was x64) I downloaded the latest Microsoft Visual C++ Redistributable for Visual Studio 2019 from the link https://visualstudio.microsoft.com/downloads/. Detailed answer given here: Android Studio install failed - unable to run mksdcard sdk tool in Windows

After downloading and installing Visual C++ ,the error "unable to run mksdcard sdk tool" was fixed, also when I try to install HAXM after this, it was install successfully. Everything was fine. I was also able to create AVD now(which was also a problem when HAXM was not install).

This may also help:

The Source

Sounds like you're doing this:

0..10.to_a

The warning is from Fixnum#to_a, not from Range#to_a. Try this instead:

(0..10).to_a

In Python 3 this can be done in 2 steps:

1. Convert timestring to datetime object
2. Multiply the timestamp of the datetime object by 1000 to convert it to milliseconds.

For example like this:

from datetime import datetime

dt_obj = datetime.strptime('20.12.2016 09:38:42,76',
                           '%d.%m.%Y %H:%M:%S,%f')
millisec = dt_obj.timestamp() * 1000

print(millisec)

Output:

1482223122760.0

strptime accepts your timestring and a format string as input. The timestring (first argument) specifies what you actually want to convert to a datetime object. The format string (second argument) specifies the actual format of the string that you have passed.

Here is the explanation of the format specifiers from the official documentation:

• %d - Day of the month as a zero-padded decimal number.
• %m - Month as a zero-padded decimal number.
• %Y - Year with century as a decimal number
• %H - Hour (24-hour clock) as a zero-padded decimal number.
• %M - Minute as a zero-padded decimal number.
• %S - Second as a zero-padded decimal number.
• %f - Microsecond as a decimal number, zero-padded on the left.

VarArgs and overloading have been mentioned. Another option is a Bloch Builder pattern, which would look something like this:

 MyObject my = new MyObjectBuilder().setParam1(value)
                                 .setParam3(otherValue)
                                 .setParam6(thirdValue)
                                 .build();

Although that pattern would be most appropriate for when you need optional parameters in a constructor.

Create a script similar to this:

#!/bin/sh -e

location=~/`date +%Y%m%d_%H%M%S`.db

mysqldump -u root --password=<your password> database_name > $location

gzip $location

Then you can edit the crontab of the user that the script is going to run as:

$> crontab -e

And append the entry

01 * * * * ~/script_path.sh

This will make it run on the first minute of every hour every day.

Then you just have to add in your rolls and other functionality and you are good to go.

Your code looks fine except the possibility that if the variable declaration is inside a dom read handler then it will not be a global variable... it will be a closure variable

jQuery(function(){
    //here it is a closure variable
    var a_href;
    $('sth a').on('click', function(e){
        a_href = $(this).attr('href');

          console.log(a_href);  
         //output is "home"

        e.preventDefault();
    }
})

To make the variable global, one solution is to declare the variable in global scope

var a_href;
jQuery(function(){
    $('sth a').on('click', function(e){
        a_href = $(this).attr('href');

          console.log(a_href);  
         //output is "home"

        e.preventDefault();
    }
})

another is to set the variable as a property of the window object

window.a_href = $(this).attr('href')

Why console printing undefined

You are getting the output as undefined because even though the variable is declared, you have not initialized it with a value, the value of the variable is set only after the a element is clicked till that time the variable will have the value undefined. If you are not declaring the variable it will throw a ReferenceError

Well, if the string really ends with the pattern, you could do this:

str = str.replace(new RegExp(list[i] + '$'), 'finish');

When you download a package with setup.py open your Terminal (Mac,Linux) or Command Prompt (Windows). Using cd and helping you with Tab button set the path right to the folder where you have downloaded the file and where there is setup.py :

iMac:~ user $ cd path/pakagefolderwithsetupfile/

Press enter, you should see something like this:

iMac:pakagefolderwithsetupfile user$

Then type after this python setup.py install :

iMac:pakagefolderwithsetupfile user$ python setup.py install

Press enter. Done!

You can change the linter for Python extension for Visual Studio Code.

In VS open the Command Palette Ctrl+Shift+P and type in one of the following commands:

Python: Select Linter

when you select a linter it will be installed. I tried flake8 and it seems issue resolved for me.

You can use the magic of POSIX parameter expansion:

bash-3.2$ FILENAME=somefile.tar.gz
bash-3.2$ echo "${FILENAME%%.*}"
somefile
bash-3.2$ echo "${FILENAME%.*}"
somefile.tar

There's a caveat in that if your filename was of the form ./somefile.tar.gz then echo ${FILENAME%%.*} would greedily remove the longest match to the . and you'd have the empty string.

(You can work around that with a temporary variable:

FULL_FILENAME=$FILENAME
FILENAME=${FULL_FILENAME##*/}
echo ${FILENAME%%.*}

)

This site explains more.

${variable%pattern}
  Trim the shortest match from the end
${variable##pattern}
  Trim the longest match from the beginning
${variable%%pattern}
  Trim the longest match from the end
${variable#pattern}
  Trim the shortest match from the beginning

I think CAST(ROUND(yourColumn,2) as varchar) should do the job.

But why do you want to do this presentational formatting in T-SQL?

Make sure to download these from here:

Also create PATH enviroment variable on you computer like this (if it doesn't exist already):

1. Right click on My Computer/Computer
2. Properties
3. Advanced system settings (or just Advanced)
4. Enviroment variables
5. If PATH variable doesn't exist among "User variables" click New (Variable name: PATH, Variable value : C:\Program Files\Java\jdk1.8.0\bin; <-- please check out the right version, this may differ as Oracle keeps updating Java). ; in the end enables assignment of multiple values to PATH variable.
6. Click OK! Done

To be sure that everything works, open CMD Prompt and type: java -version to check for Java version and javac to be sure that compiler responds.

I hope this helps. Good luck!

I like Andrew's suggestion, and in fact the CSS rule only needs to be:

:checked + label {
   font-weight: bold;
}

I like to rely on implicit association of the label and the input element, so I'd do something like this:

<label>
   <input type="checkbox"/>
   <span>Bah</span>
</label>

with CSS:

:checked + span {
    font-weight: bold;
}

Update 2018

Bootstrap 2.x

You could create a new CSS class such as:

.img-center {margin:0 auto;}

And then, add this to each IMG:

 <img src="images/2.png" class="img-responsive img-center">

OR, just override the .img-responsive if you're going to center all images..

 .img-responsive {margin:0 auto;}

Demo: http://bootply.com/86123

Bootstrap 3.x

EDIT - With the release of Bootstrap 3.0.1, the center-block class can now be used without any additional CSS..

 <img src="images/2.png" class="img-responsive center-block">

Bootstrap 4

In Bootstrap 4, the mx-auto class (auto x-axis margins) can be used to center images that are display:block. However, img is display:inline by default so text-center can be used on the parent.

<div class="container">
    <div class="row">
        <div class="col-12">
            <img class="mx-auto d-block" src="//placehold.it/200">  
        </div>
    </div>
    <div class="row">
        <div class="col-12 text-center">
            <img src="//placehold.it/200">  
        </div>
    </div>
</div>

Client validation issues can occur because of MVC bug (even in MVC 5) in jquery.validate.unobtrusive.min.js which does not accept date/datetime format in any way. Unfortunately you have to solve it manually.

My finally working solution:

$(function () {
    $.validator.methods.date = function (value, element) {
        return this.optional(element) || moment(value, "DD.MM.YYYY", true).isValid();
    }
});

You have to include before:

@Scripts.Render("~/Scripts/jquery-3.1.1.js")
@Scripts.Render("~/Scripts/jquery.validate.min.js")
@Scripts.Render("~/Scripts/jquery.validate.unobtrusive.min.js")
@Scripts.Render("~/Scripts/moment.js")

You can install moment.js using:

Install-Package Moment.js

There are a few ways to handle rendering/showing controls on the page and you should take note to what happens with each method.

Rendering and Visibility

There are some instances where elements on your page don't need to be rendered for the user because of some type of logic or database value. In this case, you can prevent rendering (creating the control on the returned web page) altogether. You would want to do this if the control doesn't need to be shown later on the client side because no matter what, the user viewing the page never needs to see it.

Any controls or elements can have their visibility set from the server side. If it is a plain old html element, you just need to set the runat attribute value to server on the markup page.

<div id="myDiv" runat="server"></div>

The decision to render the div or not can now be done in the code behind class like so:

myDiv.Visible = someConditionalBool;

If set to true, it will be rendered on the page and if it's false it won't be rendered at all, not even hidden.

Client Side Hiding

Hiding an element is done on the client side only. Meaning, it's rendered but it has a display CSS style set on it which instructs your browser to not show it to the user. This is beneficial when you want to hide/show things based on user input. It's important to know that the element CAN be hidden on the server side too as long as the element/control has runat=server set just as I explained in the previous example.

Hiding in the Code Behind Class

To hide an element that you want rendered to the page but hidden is another simple single line of code:

myDiv.Style["display"] = "none";

If you have a need to remove the display style server side, it can be done by removing the display style, or setting it to a different value like inline or block (values described here).

myDiv.Style.Remove("display");
// -- or --
myDiv.Style["display"] = "inline";

Hiding on the Client Side with javascript

Using plain old javascript, you can easily hide the same element in this manner

var myDivElem = document.getElementById("myDiv");
myDivElem.style.display = "none";

// then to show again
myDivElem.style.display = "";

jQuery makes hiding elements a little simpler if you prefer to use jQuery:

var myDiv = $("#<%=myDiv.ClientID%>");
myDiv.hide();

// ... and to show 
myDiv.show();

Yes; copy the string to a char array, sort the char array, then copy that back into a string.

static string SortString(string input)
{
    char[] characters = input.ToArray();
    Array.Sort(characters);
    return new string(characters);
}

A)

String str = "a string";
int length = str.length( ); // length == 8

http://download.oracle.com/javase/7/docs/api/java/lang/String.html#length%28%29

edit

If you want to count the number of a specific type of characters in a String, then a simple method is to iterate through the String checking each index against your test case.

int charCount = 0;
char temp;

for( int i = 0; i < str.length( ); i++ )
{
    temp = str.charAt( i );

    if( temp.TestCase )
        charCount++;
}

where TestCase can be isLetter( ), isDigit( ), etc.

Or if you just want to count everything but spaces, then do a check in the if like temp != ' '

B)

String str = "a string";
char atPos0 = str.charAt( 0 ); // atPos0 == 'a'

http://download.oracle.com/javase/7/docs/api/java/lang/String.html#charAt%28int%29

Dplyr across function has superseded _if, _at, and _all. See vignette("colwise").

dat %>% 
mutate(across(all_of(l1), as.factor),
       across(all_of(l2), as.numeric))

Calculate row means on a subset of columns:

Create a new data.frame which specifies the first column from DF as an column called ID and calculates the mean of all the other fields on that row, and puts that into column entitled 'Means':

data.frame(ID=DF[,1], Means=rowMeans(DF[,-1]))
  ID    Means
1  A 3.666667
2  B 4.333333
3  C 3.333333
4  D 4.666667
5  E 4.333333

I had a similar problem setting up eclipse.

I changed: NATIVE connection to MANUAL and cleared the proxy settings for SOCKS in Windows -> Preferences -> General -> Network connection. That fixed the problem for me.

The easiest way to do this is to open the database directly and use the .dump command, rather than attaching it after invoking the SQLite 3 shell tool.

So... (assume your OS command line prompt is $) instead of $sqlite3:

sqlite3> ATTACH database.sqlite as "attached"

From your OS command line, open the database directly:

$sqlite3 database.sqlite
sqlite3> .dump

PEP 8 is good, the only thing that i wish it came down harder on was the Tabs-vs-Spaces holy war.

Basically if you are starting a project in python, you need to choose Tabs or Spaces and then shoot all offenders on sight.

You can trigger Jenkins builds remotely and to pass parameters by using the following query.

JENKINS_URL/job/job-name/buildWithParameters?token=TOKEN_NAME&param_name1=value&param_name1=value

JENKINS_URL (can be) = https://<your domain name or server address>

TOKE_NAME can be created using configure tab

It is very simply you have to give first you have to give backgound as rgb because Internet Explorer 8 will support rgb instead rgba and then u have to give opacity like filter:alpha(opacity=50);

background:rgb(0,0,0);
filter:alpha(opacity=50);

<div>
    <input type="checkbox">
    <img src="/image.png" />
</div>

input[type="checkbox"]
{
    margin-top: -50%;
    vertical-align: middle;
}

I didn't want to reinstall everything because I have so many SDK versions installed and my development environment is set up just right. Getting it set up again takes way too long.

What worked for me was deleting, then re-creating the Android Virtual Device, being certain to put in a value for SD Card Size (I used 200 MiB).

Additional information:

while the above does fix the problem temporarily, it is recurring. I just tried my application within Android Studio and saw this in the output log which I did not notice before in Eclipse:

"/Applications/Android Studio.app/sdk/tools/emulator" -avd AVD_for_Nexus_S_by_Google -netspeed full -netdelay none

WARNING: Data partition already in use. Changes will not persist!
WARNING: SD Card image already in use: /Users/[user]/.android/avd/AVD_for_Nexus_S_by_Google.avd/sdcard.img
ko:Snapshot storage already in use: /Users/[user]/.android/avd/AVD_for_Nexus_S_by_Google.avd/snapshots.img

I suspect that changes to the log are not saving to the SD Card, so when LogCat tries to access the logs, they aren't there, causing the error message. The act of deleting the AVD and re-creating it removes the files, and the next launch is a fresh launch, allowing LogCat to access the virtual SD Card.

You might want to start with scapy.

Remember that MySQL keeps a simple index on a column after deleting foreign key. So, if you need to change 'references' column you should do it in 3 steps

• drop original FK
• drop an index (names as previous fk, using drop index clause)
• create new FK

Using sn.exe utility:

sn -T YourAssembly.dll

or loading the assembly in Reflector.

In the case of some programs, these errors are normal and should not be fixed.

I get these error messages when compiling the program phrap (for example). This program happens to contain code that modifies or replaces some built in functions, and when I include the appropriate header files to fix the warnings, GCC instead generates a bunch of errors. So fixing the warnings effectively breaks the build.

If you got the source as part of a distribution that should compile normally, the errors might be normal. Consult the documentation to be sure.

functionNameAsString = sys._getframe().f_code.co_name

I wanted a very similar thing because I wanted to put the function name in a log string that went in a number of places in my code. Probably not the best way to do that, but here's a way to get the name of the current function.

This was an enormously helpful link to find:

An official document describing the changes made to open ssl in PHP 5.6 From here I learned of one more parameter I should have set to false: "verify_peer_name"=>false

Note: This has very significant security implications. Disabling verification potentially permits a MITM attacker to use an invalid certificate to eavesdrop on the requests. While it may be useful to do this in local development, other approaches should be used in production.

So my working code looks like this:

<?php
$arrContextOptions=array(
    "ssl"=>array(
        "verify_peer"=>false,
        "verify_peer_name"=>false,
    ),
);  

$response = file_get_contents("https://maps.co.weber.ut.us/arcgis/rest/services/SDE_composite_locator/GeocodeServer/findAddressCandidates?Street=&SingleLine=3042+N+1050+W&outFields=*&outSR=102100&searchExtent=&f=json", false, stream_context_create($arrContextOptions));

echo $response; ?>

Set validateTLSCertificates property to false for your JSoup command.

If you are using numpy you can use np.argsort to get the sorted indices and apply those indices to the list. This works for any number of list that you would want to sort.

import numpy as np

arr1 = np.array([4,3,1,32,21])
arr2 = arr1 * 10
sorted_idxs = np.argsort(arr1)

print(sorted_idxs)
>>> array([2, 1, 0, 4, 3])

print(arr1[sorted_idxs])
>>> array([ 1,  3,  4, 21, 32])

print(arr2[sorted_idxs])
>>> array([ 10,  30,  40, 210, 320])

Use jQuery Form Notifier - it is one of the most popular jQuery plugins and doesn't suffer from the bugs some of the other jQuery suggestions here do (for example, you can freely style the watermark, without worrying if it will get saved to the database).

jQuery Watermark uses a single CSS style directly on the form elements (I noticed that CSS font-size properties applied to the watermark also affected the text boxes -- not what I wanted). The plus with jQuery Watermark is you can drag-drop text into fields (jQuery Form Notifier doesn't allow this).

Another one suggested by some others (the one at digitalbrush.com), will accidentally submit the watermark value to your form, so I strongly recommend against it.
