Programs & Examples On #Zimbra

Most of it is explained in the GC Tuning Guide (which you would do well to read anyway).

The command line option -verbose:gc causes information about the heap and garbage collection to be printed at each collection. For example, here is output from a large server application:

[GC 325407K->83000K(776768K), 0.2300771 secs]
[GC 325816K->83372K(776768K), 0.2454258 secs]
[Full GC 267628K->83769K(776768K), 1.8479984 secs]

Here we see two minor collections followed by one major collection. The numbers before and after the arrow (e.g., 325407K->83000K from the first line) indicate the combined size of live objects before and after garbage collection, respectively. After minor collections the size includes some objects that are garbage (no longer alive) but that cannot be reclaimed. These objects are either contained in the tenured generation, or referenced from the tenured or permanent generations.

The next number in parentheses (e.g., (776768K) again from the first line) is the committed size of the heap: the amount of space usable for java objects without requesting more memory from the operating system. Note that this number does not include one of the survivor spaces, since only one can be used at any given time, and also does not include the permanent generation, which holds metadata used by the virtual machine.

The last item on the line (e.g., 0.2300771 secs) indicates the time taken to perform the collection; in this case approximately a quarter of a second.

The format for the major collection in the third line is similar.

The format of the output produced by -verbose:gc is subject to change in future releases.

I'm not certain why there's a PSYoungGen in yours; did you change the garbage collector?

Okay, just to clarify things that have already been posted.

You should have the directory com, containing the directory company, containing the directory example, containing the file MyClass.java.

From the folder containing com, run:

$ javac com\company\example\MyClass.java

Then:

$ java com.company.example.MyClass
Hello from MyClass!

These must both be done from the root of the source tree. Otherwise, javac and java won't be able to find any other packages (in fact, java wouldn't even be able to run MyClass).

A short example

I created the folders "testpackage" and "testpackage2". Inside testpackage, I created TestPackageClass.java containing the following code:

package testpackage;

import testpackage2.MyClass;

public class TestPackageClass {
    public static void main(String[] args) {
        System.out.println("Hello from testpackage.TestPackageClass!");
        System.out.println("Now accessing " + MyClass.NAME);
    }
}

Inside testpackage2, I created MyClass.java containing the following code:

package testpackage2;
public class MyClass {
    public static String NAME = "testpackage2.MyClass";
}

From the directory containing the two new folders, I ran:

C:\examples>javac testpackage\*.java

C:\examples>javac testpackage2\*.java

Then:

C:\examples>java testpackage.TestPackageClass
Hello from testpackage.TestPackageClass!
Now accessing testpackage2.MyClass

Does that make things any clearer?

System.err.println("Someone is Restarting me...");
setVisible(false);
try {
    Thread.sleep(600);
} catch (InterruptedException e1) {
    e1.printStackTrace();
}
setVisible(true);

I guess you don't really want to stop the application, but to "Restart" it. For that, you could use this and add your "Reset" before the sleep and after the invisible window.

How about typing document.cookie into the console? It just shows the values, but it's something.

Well, to get rid of this you need to set phpMyadmin variable to either 0 that is unlimited or whichever value in seconds you find suitable for your needs. Or you could always use CLI(command line interface) to not even get such errors(For which you would like to take a look at this link.

Now about the error here, first on the safe side make sure you have set PHP parameters properly so that you can upload large files and can use maximum execution time from that end. If not, go ahead and set below three parameters from php.ini file,

1. max_execution_time=3000000 (Set this as per your req)
2. post_max_size=4096M
3. upload_max_filesize=4096M

Once that's done get back to finding phpMyadmin config file named something like "config.default.php". On XAMPP you will find it under "C:\xampp\phpMyAdmin\libraries" folder. Open the file called config.default.php and set :

$cfg['ExecTimeLimit'] = 0;

Once set, restart your MySQL and Apache and go import your database.

Enjoy... :)

well, char * means a pointer point to char, it is different from char array.

char amessage[] = "this is an array";  /* define an array*/
char *pmessage = "this is a pointer"; /* define a pointer*/

And, char ** means a pointer point to a char pointer.

You can look some books about details about pointer and array.

If working in Java 1.8 you can leverage the DateTimeFormatterBuilder

public static boolean isTimeStampValid(String inputString)
{
    DateTimeFormatterBuilder dateTimeFormatterBuilder = new DateTimeFormatterBuilder()
            .append(DateTimeFormatter.ofPattern("" + "[yyyy-MM-dd'T'HH:mm:ss.SSSZ]" + "[yyyy-MM-dd]"));

    DateTimeFormatter dateTimeFormatter = dateTimeFormatterBuilder.toFormatter();

    try {
        dateTimeFormatter.parse(inputString);
        return true;
    } catch (DateTimeParseException e) {
        return false;
    }
}

See post: Java 8 Date equivalent to Joda's DateTimeFormatterBuilder with multiple parser formats?

Just send the sizeToFit message to the UITextView. It will adjust its own height to just fit its text. It will not change its own width or origin.

There are already great solutions on this page, but all have assumed the dataset is uniformly/evenly sampled/distributed. I will try to provide a more general example of randomly sampled data. I will also use this MATLAB tutorial as an example:

Adding the required modules:

import numpy as np
import matplotlib.pyplot as plt
import scipy.fftpack
import scipy.signal

Generating sample data:

N = 600 # Number of samples
t = np.random.uniform(0.0, 1.0, N) # Assuming the time start is 0.0 and time end is 1.0
S = 1.0 * np.sin(50.0 * 2 * np.pi * t) + 0.5 * np.sin(80.0 * 2 * np.pi * t)
X = S + 0.01 * np.random.randn(N) # Adding noise

Sorting the data set:

order = np.argsort(t)
ts = np.array(t)[order]
Xs = np.array(X)[order]

Resampling:

T = (t.max() - t.min()) / N # Average period
Fs = 1 / T # Average sample rate frequency
f = Fs * np.arange(0, N // 2 + 1) / N; # Resampled frequency vector
X_new, t_new = scipy.signal.resample(Xs, N, ts)

Plotting the data and resampled data:

plt.xlim(0, 0.1)
plt.plot(t_new, X_new, label="resampled")
plt.plot(ts, Xs, label="org")
plt.legend()
plt.ylabel("X")
plt.xlabel("t")

Now calculating the FFT:

Y = scipy.fftpack.fft(X_new)
P2 = np.abs(Y / N)
P1 = P2[0 : N // 2 + 1]
P1[1 : -2] = 2 * P1[1 : -2]

plt.ylabel("Y")
plt.xlabel("f")
plt.plot(f, P1)

P.S. I finally got time to implement a more canonical algorithm to get a Fourier transform of unevenly distributed data. You may see the code, description, and example Jupyter notebook here.

This is an old question, but there is another subtle way this message can happen. It's explained pretty well here, in the docs.

Imagine this scenerio:

try {
  // code that triggers a pdo exception
} catch (Exception $e) {
  throw new MyCustomExceptionHandler($e);
}

And MyCustomExceptionHandler is defined roughly like:

class MyCustomExceptionHandler extends Exception {
  public function __construct($e) {
    parent::__construct($e->getMessage(), $e->getCode());
  }
}

This will actually trigger a new exception in the custom exception handler because the Exception class is expecting a number for the second parameter in its constructor, but PDOException might have dynamically changed the return type of $e->getCode() to a string.

A workaround for this would be to define you custom exception handler like:

class MyCustomExceptionHandler extends Exception {
  public function __construct($e) {
    parent::__construct($e->getMessage());
    $this->code = $e->getCode();
  }
}

You also get this error if you do not create and populate your tables in the right order. For example, according to your schema, Comments table needs user_id, project_id, task_id and data_type_id. This means that Users table, Projects table, Task table and Data_Type table must already have exited and have values in them before you can reference their ids or any other column.

In Laravel this would mean calling your database seeders in the right order:

class DatabaseSeeder extends Seeder
{
    /**
     * Seed the application's database.
     *
     * @return void
     */
    public function run()
    {
        $this->call(UserSeeder::class);
        $this->call(ProjectSeeder::class);
        $this->call(TaskSeeder::class);
        $this->call(DataTypeSeeder::class);
        $this->call(CommentSeeder::class);
    }
}

This was how I solved a similar issue.

_MSC_VER should be defined to a specific version number. You can either #ifdef on it, or you can use the actual define and do a runtime test. (If for some reason you wanted to run different code based on what compiler it was compiled with? Yeah, probably you were looking for the #ifdef. :))

for i=1,#target do
    game.Players.target[i].Character:BreakJoints()
end

Is incorrect, if "target" contains "FakeNameHereSoNoStalkers" then the run code would be:

game.Players.target.1.Character:BreakJoints()

Which is completely incorrect.

c = game.Players:GetChildren()

Never use "Players:GetChildren()", it is not guaranteed to return only players.

Instead use:

c = Game.Players:GetPlayers()

if msg:lower()=="me" then
    table.insert(people, source)
    return people

Here you add the player's name in the list "people", where you in the other places adds the player object.

Fixed code:

local Admins = {"FakeNameHereSoNoStalkers"}

function Kill(Players)
    for i,Player in ipairs(Players) do
        if Player.Character then
            Player.Character:BreakJoints()
        end
    end
end

function IsAdmin(Player)
    for i,AdminName in ipairs(Admins) do
        if Player.Name:lower() == AdminName:lower() then return true end
    end
    return false
end

function GetPlayers(Player,Msg)
    local Targets = {}
    local Players = Game.Players:GetPlayers()

    if Msg:lower() == "me" then
        Targets = { Player }
    elseif Msg:lower() == "all" then
        Targets = Players
    elseif Msg:lower() == "others" then
        for i,Plr in ipairs(Players) do
            if Plr ~= Player then
                table.insert(Targets,Plr)
            end
        end
    else
        for i,Plr in ipairs(Players) do
            if Plr.Name:lower():sub(1,Msg:len()) == Msg then
                table.insert(Targets,Plr)
            end
        end
    end
    return Targets
end

Game.Players.PlayerAdded:connect(function(Player)
    if IsAdmin(Player) then
        Player.Chatted:connect(function(Msg)
            if Msg:lower():sub(1,6) == ":kill " then
                Kill(GetPlayers(Player,Msg:sub(7)))
            end
        end)
    end
end)

From the tutorial:

from sqlalchemy import or_
filter(or_(User.name == 'ed', User.name == 'wendy'))

I don't understand how can datenwolf`s index generation can be correct. But still I find his solution rather clear. This is what I get after some thinking:

inline void push_indices(vector<GLushort>& indices, int sectors, int r, int s) {
    int curRow = r * sectors;
    int nextRow = (r+1) * sectors;

    indices.push_back(curRow + s);
    indices.push_back(nextRow + s);
    indices.push_back(nextRow + (s+1));

    indices.push_back(curRow + s);
    indices.push_back(nextRow + (s+1));
    indices.push_back(curRow + (s+1));
}

void createSphere(vector<vec3>& vertices, vector<GLushort>& indices, vector<vec2>& texcoords,
             float radius, unsigned int rings, unsigned int sectors)
{
    float const R = 1./(float)(rings-1);
    float const S = 1./(float)(sectors-1);

    for(int r = 0; r < rings; ++r) {
        for(int s = 0; s < sectors; ++s) {
            float const y = sin( -M_PI_2 + M_PI * r * R );
            float const x = cos(2*M_PI * s * S) * sin( M_PI * r * R );
            float const z = sin(2*M_PI * s * S) * sin( M_PI * r * R );

            texcoords.push_back(vec2(s*S, r*R));
            vertices.push_back(vec3(x,y,z) * radius);
            push_indices(indices, sectors, r, s);
        }
    }
}

From documentation:

You cannot insert the values TRUE and FALSE into a database column. You cannot select or fetch column values into a BOOLEAN variable. Functions called from a SQL query cannot take any BOOLEAN parameters. Neither can built-in SQL functions such as TO_CHAR; to represent BOOLEAN values in output, you must use IF-THEN or CASE constructs to translate BOOLEANvalues into some other type, such as 0 or 1, 'Y' or 'N', 'true' or 'false', and so on.

You will need to make a wrapper function that takes an SQL datatype and use it instead.

You would still need to go through the DataTable class. But you can do so using your DataRow instance by using the Table property.

foreach (DataColumn c in dr.Table.Columns)  //loop through the columns. 
{
    MessageBox.Show(c.ColumnName);
}

I like to do this with a straight SQL query, rather than messing about with the SQL Developer application.

Here's how I just did it. Best to read through this and understand what's going on, so you can tweak it to fit your needs...

WITH all_primary_keys AS (
  SELECT constraint_name AS pk_name,
         table_name
    FROM all_constraints
   WHERE owner = USER
     AND constraint_type = 'P'
)
  SELECT ac.table_name || ' table has a foreign key called ' || upper(ac.constraint_name)
         || ' which references the primary key ' || upper(ac.r_constraint_name) || ' on table ' || apk.table_name AS foreign_keys
    FROM all_constraints ac
         LEFT JOIN all_primary_keys apk
                ON ac.r_constraint_name = apk.pk_name
   WHERE ac.owner = USER
     AND ac.constraint_type = 'R'
     AND ac.table_name = nvl(upper(:table_name), ac.table_name)
ORDER BY ac.table_name, ac.constraint_name
;

I think all the answers do not really point the problem because all of them work in specific scenarios. But if you need to cover all the cases follow the points bellow:

Depending on where you need the status bar light style you should always have in mind these 3 points:

1)If you need the status bar at the launch screen or in other places, where you can't control it (not in view controllers, but rather some system controlled elements/moments like Launch Screen) You go to your project settings

2) if you have a controller inside a navigation controller You can change it in the interface builder as follows:

a) Select the navigation bar of your navigation controller

b) Then set the style of the navigation bar to "Black", because this means you'll have a "black" -> dark background under your status bar, so it will set the status bar to white

Or do it in code as follows

navigationController?.navigationBar.barStyle = UIBarStyle.Black

3) If you have the controller alone that needs to have it's own status bar style and it's not embedded in some container structure as a UINavigationController

Set the status bar style in code for the controller:

It is an annotation to suppress compile warnings about unchecked generic operations (not exceptions), such as casts. It essentially implies that the programmer did not wish to be notified about these which he is already aware of when compiling a particular bit of code.

You can read more on this specific annotation here:

SuppressWarnings

Additionally, Oracle provides some tutorial documentation on the usage of annotations here:

Annotations

As they put it,

"The 'unchecked' warning can occur when interfacing with legacy code written before the advent of generics (discussed in the lesson titled Generics)."

Instead of hard-coding your app constants and doing a switch on the environment (I'll explain how to do that in a moment), I suggest using the twelve factor suggestion of having your build process define your BASE_URL and your API_KEY.

To answer how to expose your environment to react-native, I suggest using Babel's babel-plugin-transform-inline-environment-variables.

To get this working you need to download the plugin and then you will need to setup a .babelrc and it should look something like this:

{
  "presets": ["react-native"],
  "plugins": [
    "transform-inline-environment-variables"
  ]
}

And so if you transpile your react-native code by running API_KEY=my-app-id react-native bundle (or start, run-ios, or run-android) then all you have to do is have your code look like this:

const apiKey = process.env['API_KEY'];

And then Babel will replace that with:

const apiKey = 'my-app-id';

Hope this helps!

If you have a List of type string that you want in a drop down list I do the following:

EDIT: Clarified, making it a fuller example.

public class ShipDirectory
{
    public string ShipDirectoryName { get; set; }
    public List<string> ShipNames { get; set; }
}

ShipDirectory myShipDirectory = new ShipDirectory()
{
    ShipDirectoryName = "Incomming Vessels",
    ShipNames = new List<string>(){"A", "A B"},
}

myShipDirectory.ShipNames.Add("Aunt Bessy");

@Html.DropDownListFor(x => x.ShipNames, new SelectList(Model.ShipNames), "Select a Ship...", new { @style = "width:500px" })

Which gives a drop down list like so:

<select id="ShipNames" name="ShipNames" style="width:500px">
    <option value="">Select a Ship...</option>
    <option>A</option>
    <option>A B</option>
    <option>Aunt Bessy</option>
</select>

To get the value on a controllers post; if you are using a model (e.g. MyViewModel) that has the List of strings as a property, because you have specified x => x.ShipNames you simply have the method signature as (because it will be serialised/deserialsed within the model):

public ActionResult MyActionName(MyViewModel model)

Access the ShipNames value like so: model.ShipNames

If you just want to access the drop down list on post then the signature becomes:

public ActionResult MyActionName(string ShipNames)

EDIT: In accordance with comments have clarified how to access the ShipNames property in the model collection parameter.

I don't believe it's possible to guarantee that using only standard POSIX calls. Like real life, once a child is spawned, it has a life of its own.

It is possible for the parent process to catch most possible termination events, and attempt to kill the child process at that point, but there's always some that can't be caught.

For example, no process can catch a SIGKILL. When the kernel handles this signal it will kill the specified process with no notification to that process whatsoever.

To extend the analogy - the only other standard way of doing it is for the child to commit suicide when it finds that it no longer has a parent.

There is a Linux-only way of doing it with prctl(2) - see other answers.

You can get the events from pygame and then watch out for the KEYDOWN event, instead of looking at the keys returned by get_pressed()(which gives you keys that are currently pressed down, whereas the KEYDOWN event shows you which keys were pressed down on that frame).

What's happening with your code right now is that if your game is rendering at 30fps, and you hold down the left arrow key for half a second, you're updating the location 15 times.

events = pygame.event.get()
for event in events:
    if event.type == pygame.KEYDOWN:
        if event.key == pygame.K_LEFT:
            location -= 1
        if event.key == pygame.K_RIGHT:
            location += 1

To support continuous movement while a key is being held down, you would have to establish some sort of limitation, either based on a forced maximum frame rate of the game loop or by a counter which only allows you to move every so many ticks of the loop.

move_ticker = 0
keys=pygame.key.get_pressed()
if keys[K_LEFT]:
    if move_ticker == 0:
        move_ticker = 10
        location -= 1
        if location == -1:
            location = 0
if keys[K_RIGHT]:
    if move_ticker == 0:   
        move_ticker = 10     
        location+=1
        if location == 5:
            location = 4

Then somewhere during the game loop you would do something like this:

if move_ticker > 0:
    move_ticker -= 1

This would only let you move once every 10 frames (so if you move, the ticker gets set to 10, and after 10 frames it will allow you to move again)

This is the code for VB.Net

Private Shared Sub Main()
    Using mutex As New Mutex(False, appGuid)
        If Not mutex.WaitOne(0, False) Then
              MessageBox.Show("Instance already running", "ERROR", MessageBoxButtons.OK, MessageBoxIcon.Error)
            Return
        End If

        Application.Run(New Form1())
    End Using
End Sub

This is the code for C#

private static void Main()
{
    using (Mutex mutex = new Mutex(false, appGuid)) {
        if (!mutex.WaitOne(0, false)) {
            MessageBox.Show("Instance already running", "ERROR", MessageBoxButtons.OK, MessageBoxIcon.Error);
            return;
        }

        Application.Run(new Form1());
    }
}

Assume B and C are overriding inherited method and their own implementation. Now D inherits both B & C using multiple inheritance. D should inherit the overridden method.The Question is which overridden method will be used? Will it be from B or C? Here we have an ambiguity. To exclude such situation multiple inheritance was not used in Java.

Since link to this question shows up on very top of returned results when you search for "php MSVCR110.dll" (not to mention it got 100k+ views and growing), here're some additional notes that you may find handy in your quest to solve MSVCR110.dll mistery...

The approach described in the answer is valid not only for MSVCR110.dll case but also applies when you are looking for other versions, like newer MSVCR71.dll and I updated the answer to include VC15 even it's beyond scope of the original question.

On http://windows.php.net/ you can read:

VC9, VC11 and VC15

More recent versions of PHP are built with VC9, VC11 or VC15 (Visual Studio 2008, 2012 or 2015 compiler respectively) and include improvements in performance and stability.

The VC9 builds require you to have the Visual C++ Redistributable for Visual Studio 2008 SP1 x86 or x64 installed.

The VC11 builds require to have the Visual C++ Redistributable for Visual Studio 2012 x86 or x64 installed.

The VC15 builds require to have the Visual C++ Redistributable for Visual Studio 2015 x86 or x64 installed.

This is quite crucial as you not only need to get Visual C++ Redistributable installed but you also need the right version of it, and which one is right and correct, depends on what PHP build you are actually going to use. Pay attention to what version of PHP for Windows you are fetching, especially pay attention to this "VCxx" suffix, because if you install PHP that requires VC9 while having redistributables VC11 installed it is not going to work as run-time dependency is simply not fulfilled. Contrary to what some may think, you need exactly the version required, as newer (higher) releases does NOT cover older (lower) versions. so i.e. VC11 is not providing VC9 compatibility. Also VC15 is neither fulfilling VC11 nor VC9 dependency. It is just VC15 and NOTHING ELSE. Deal with it :)

For example, archive name php-5.6.4-nts-Win32-VC11-x86 tells us the following

1. it provides PHP v5.6.4,
2. PHP build is Non-Thread Safe (nts),
3. it provides binaries for Windows (Win32),
4. to run, Visual Studio 2012 redistributable (VC11) is required,
5. binaries are 32-bit (x86),

Most searches I did lead to VC9 of redistributables, so in case of constant failures to make thing works, if possible, try installing different PHP build, to see if you by any chance do not face mismatching versions.

Download links

Note that you are using 32-bit version of PHP, so you need 32-bit redistributable (x86) even if your version of Windows is 64-bit!

• VC9: Visual C++ Redistributable for Visual Studio 2008: x86 or x64
• VC11: Visual C++ Redistributable for Visual Studio 2012: x86 or x64
• VC15: Visual C++ Redistributable for Visual Studio 2015: x86 or x64
• VC17: Visual C++ Redistributable for Visual Studio 2017: x86 or x64

According to the documentation, just like with any css selector, you can specify as many conditions as you want, and they are treated as logical 'OR'.

This example returns a list of all div elements within the document with a class of either "note" or "alert":

var matches = document.querySelectorAll("div.note, div.alert");

source: https://developer.mozilla.org/en-US/docs/Web/API/Document/querySelectorAll

Meanwhile to get the 'AND' functionality you can for example simply use a multiattribute selector, as jquery says:

https://api.jquery.com/multiple-attribute-selector/

ex. "input[id][name$='man']" specifies both id and name of the element and both conditions must be met. For classes it's as obvious as ".class1.class2" to require object of 2 classes.

All possible combinations of both are valid, so you can easily get equivalent of more sophisticated 'OR' and 'AND' expressions.

For completeness:

>>> def divide(x, y):
...     try:
...         result = x / y
...     except ZeroDivisionError:
...         print("division by zero!")
...     else:
...         print("result is", result)
...     finally:
...         print("executing finally clause")

Also note that you can capture the exception like this:

>>> try:
...     this_fails()
... except ZeroDivisionError as err:
...     print("Handling run-time error:", err)

...and re-raise the exception like this:

>>> try:
...     raise NameError('HiThere')
... except NameError:
...     print('An exception flew by!')
...     raise

You have it exactly right, all you have to do is set selectedIndex in your ng-click.

ng-click="selectedIndex = 1"

Here is how I implemented a set of buttons that change the ng-view, and highlights the button of the currently selected view.

<div id="sidebar" ng-init="partial = 'main'">
    <div class="routeBtn" ng-class="{selected:partial=='main'}" ng-click="router('main')"><span>Main</span></div>
    <div class="routeBtn" ng-class="{selected:partial=='view1'}" ng-click="router('view1')"><span>Resume</span></div>
    <div class="routeBtn" ng-class="{selected:partial=='view2'}" ng-click="router('view2')"><span>Code</span></div>
    <div class="routeBtn" ng-class="{selected:partial=='view3'}" ng-click="router('view3')"><span>Game</span></div>
  </div>

and this in my controller.

$scope.router = function(endpoint) {
    $location.path("/" + ($scope.partial = endpoint));
};

Have you tried..

curl_setopt($process, CURLOPT_SSL_VERIFYPEER, false);

If you are consuming a trusted source you can skip the verify.

If someone is using @Sceduled this might work for you.

@Scheduled(cron = "${name-of-the-cron:0 0/30 * * * ?}")

This worked for me.

Actually for Bootstrap 3 you also need to override the .modal-open class on body.

    body.modal-open, 
    .modal-open 
    .navbar-fixed-top, 
    .modal-open 
    .navbar-fixed-bottom {
     margin-right: 15px; /*<-- to margin-right: 0px;*/
    }

If you're trying to run a program using a scripting language, you may need to include the full path of the scripting language and the file to execute. For example:

exec('/usr/local/bin/node /usr/local/lib/node_modules/uglifycss/uglifycss in.css > out.css');

Try to use it via [ngClass] property:

<div class="button" [ngClass]="{active: isOn, disabled: isDisabled}"
         (click)="toggle(!isOn)">
         Click me!
     </div>`,

It's not Twitter bootstrap specific, it is a normal HTML5 component and you can specify the range with the min and max attributes (in your case only the first attribute). For example:

<div>                       _x000D_
    <input type="number" id="replyNumber" min="0" data-bind="value:replyNumber" />_x000D_
</div>

I'm not sure if only integers are allowed by default in the control or not, but else you can specify the step attribute:

<div>                       _x000D_
    <input type="number" id="replyNumber" min="0" step="1" data-bind="value:replyNumber" />_x000D_
</div>

Now only numbers higher (and equal to) zero can be used and there is a step of 1, which means the values are 0, 1, 2, 3, 4, ... .

BE AWARE: Not all browsers support the HTML5 features, so it's recommended to have some kind of JavaScript fallback (and in your back-end too) if you really want to use the constraints.

For a list of browsers that support it, you can look at caniuse.com.

In your activity, the following function getIpAddress(context) returns the phone's IP address:

public static String getIpAddress(Context context) {
    WifiManager wifiManager = (WifiManager) context.getApplicationContext()
                .getSystemService(WIFI_SERVICE);

    String ipAddress = intToInetAddress(wifiManager.getDhcpInfo().ipAddress).toString();

    ipAddress = ipAddress.substring(1);

    return ipAddress;
}

public static InetAddress intToInetAddress(int hostAddress) {
    byte[] addressBytes = { (byte)(0xff & hostAddress),
                (byte)(0xff & (hostAddress >> 8)),
                (byte)(0xff & (hostAddress >> 16)),
                (byte)(0xff & (hostAddress >> 24)) };

    try {
        return InetAddress.getByAddress(addressBytes);
    } catch (UnknownHostException e) {
        throw new AssertionError();
    }
}

I had the same issue using SQLite. My problem was that DB_DATABASE was pointing to the wrong file location.

Create the sqlite file with the touch command and output the file path using php artisan tinker.

$ touch database/database.sqlite
$ php artisan tinker
Psy Shell v0.8.0 (PHP 5.6.27 — cli) by Justin Hileman
>>> database_path(‘database.sqlite’)
=> "/Users/connorleech/Projects/laravel-5-rest-api/database/database.sqlite"

Then output that exact path to the DB_DATABASE variable.

DB_CONNECTION=sqlite
DB_HOST=127.0.0.1
DB_PORT=3306
DB_DATABASE=/Users/connorleech/Projects/laravel-5-rest-api/database/database.sqlite
DB_USERNAME=homestead
DB_PASSWORD=secret

Without the correct path you will get the access denied error

Option 1 Faster Than Option 2

Because Option 2 creates a new List reference, and then creates an n element array from the List (option 1 perfectly sizes the output array). However, first you need to fix the off by one bug. Use < (not <=). Like,

String[] out = new String[n];
for(int i = 0; i < n; i++) {
    out[i] = in.get(i);
}

function getFacebookImageFromURL($url)
{
  $headers = get_headers($url, 1);
  if (isset($headers['Location']))
  {
    return $headers['Location'];
  }
}

$url = 'https://graph.facebook.com/zuck/picture?type=large';
$imageURL = getFacebookImageFromURL($url);

Java doesn't support associative arrays, however this could easily be achieved using a Map. E.g.,

Map<String, String> map = new HashMap<String, String>();
map.put("name", "demo");
map.put("fname", "fdemo");
// etc

map.get("name"); // returns "demo"

Even more accurate to your example (since you can replace String with any object that meet your needs) would be to declare:

List<Map<String, String>> data = new ArrayList<>();
data.add(0, map);
data.get(0).get("name");

Mostly if you need a concurrent list it is inside a model object (as you should not use abstract data types like a list to represent a node in a application model graph) or it is part of a particular service, you can synchronize the access yourself.

class MyClass {
  List<MyType> myConcurrentList = new ArrayList<>();
  void myMethod() {
    synchronzied(myConcurrentList) {
      doSomethingWithList;
    }
  }
}

Often this is enough to get you going. If you need to iterate, iterate over a copy of the list not the list itself and only synchronize the part where you copy the list not while you are iterating over it.

Also when concurrently working on a list you usually do something more than just adding or removing or copying, meaning that the operation becomes meaningful enough to warrent its own method and the list becomes member of a special class representing just this particular list with thread safe behavior.

Even if I agree that a concurrent list implementation is needed and Vector / Collections.sychronizeList(list) do not do the trick as for sure you need something like compareAndAdd or compareAndRemove or get(..., ifAbsentDo), even if you have a ConcurrentList implementation developers often introduce bugs by not considering what is the true transaction when working with a concurrent lists (and maps).

These scenarios where the transactions are too small for what the intended purpose of the interaction with a concurrent ADT (abstract data type) always lead to me hide the list in a special class and synchronizing access to this class objects method using the synchronized on the method level. Its the only way to be sure that the transactions are correct.

I have seen too many bugs to do it any other way - at least if the code is important and handles something like money or security or guarantees some quality of service measures (e.g sending message at least once and only once).

I think you could use the following HTML and CSS combo instead:

<li>
  <a href="#">Backback</a>
</li>

Then use CSS background for the basket visibility on hover:

.listblock ul li a {
    padding: 5px 30px 5px 10px;
    display: block;
}

.listblock ul li a:hover {
    background: transparent url('../img/basket.png') no-repeat 3px 170px;
}

Simples!

I ran into a similar problem and this is how I did it. Using &modifying your code appropriately:

   int main()
   {
   int input;
   vector<int> V;
   cout << "Enter your numbers to be evaluated: " 
   << '\n' << "type "done" & keyboard Enter to stop entry" 
   <<   '\n';
   while ( (cin >> input) && input != "done") {
   V.push_back(input);
    }
   write_vector(V);
   return 0;
  }
   

If the project is maven placed it in src/main/resources, in the package phase it will copy it in ../WEB-INF/classes/hibernate.cfg.xml

I tried almost everything from this question, Getting path of an R script, Get the path of current script, Find location of current .R file and R command for setting working directory to source file location in Rstudio, but at the end found myself manually browsing the CRAN table and found

which provides current_filename() function, which returns proper full path of the script when sourcing in RStudio and also when invoking via R or RScript executable.

You have two objects both named bank_holiday -- one a list and one a function. Disambiguate the two.

bank_holiday[month] is raising an error because Python thinks bank_holiday refers to the function (the last object bound to the name bank_holiday), whereas you probably intend it to mean the list.

There is a way to convert upper case to lower WITHOUT doing if tests, and it's pretty straight-forward. The isupper() function/macro's use of clocale.h should take care of problems relating to your location, but if not, you can always tweak the UtoL[] to your heart's content.

Given that C's characters are really just 8-bit ints (ignoring the wide character sets for the moment) you can create a 256 byte array holding an alternative set of characters, and in the conversion function use the chars in your string as subscripts into the conversion array.

Instead of a 1-for-1 mapping though, give the upper-case array members the BYTE int values for the lower-case characters. You may find islower() and isupper() useful here.

The code looks like this...

#include <clocale>
static char UtoL[256];
// ----------------------------------------------------------------------------
void InitUtoLMap()  {
    for (int i = 0; i < sizeof(UtoL); i++)  {
        if (isupper(i)) {
            UtoL[i] = (char)(i + 32);
        }   else    {
            UtoL[i] = i;
        }
    }
}
// ----------------------------------------------------------------------------
char *LowerStr(char *szMyStr) {
    char *p = szMyStr;
    // do conversion in-place so as not to require a destination buffer
    while (*p) {        // szMyStr must be null-terminated
        *p = UtoL[*p];  
        p++;
    }
    return szMyStr;
}
// ----------------------------------------------------------------------------
int main() {
    time_t start;
    char *Lowered, Upper[128];
    InitUtoLMap();
    strcpy(Upper, "Every GOOD boy does FINE!");

    Lowered = LowerStr(Upper);
    return 0;
}

This approach will, at the same time, allow you to remap any other characters you wish to change.

This approach has one huge advantage when running on modern processors, there is no need to do branch prediction as there are no if tests comprising branching. This saves the CPU's branch prediction logic for other loops, and tends to prevent pipeline stalls.

Some here may recognize this approach as the same one used to convert EBCDIC to ASCII.

This works for MVC 5

@Html.ActionLink("LinkText", "ActionName", new { id = item.id }, new { @class = "btn btn-success" })

this worked for me.

$(document).ready(function () {
    $("#datePicker").datetimepicker({
        format: 'DD/MM/YYYY HH:mm:ss',
        defaultDate: new Date(),
    });
}

Maybe one of the easiest solutions would be to use the x descriptor of the srcset attribute as such:

<!-- With a 80% size reduction (1/0.8=1.25) -->

<!-- With a 50% size reduction (1/0.5=2) -->

Try this:

<?php
//This function prints a text array as an html list.
function alist ($array) {  
  $alist = "<ul>";
  for ($i = 0; $i < sizeof($array); $i++) {
    $alist .= "<li>$array[$i]";
  }
  $alist .= "</ul>";
  return $alist;
}
//Try to get ImageMagick "convert" program version number.
exec("convert -version", $out, $rcode);
//Print the return code: 0 if OK, nonzero if error. 
echo "Version return code is $rcode <br>"; 
//Print the output of "convert -version"    
echo alist($out); 
?>

As an aside, when trying to diagnose a similar bug I realised that jquery's ajax error callback returns a status of "timeout" if it failed due to a timeout.

Here's an example:

$.ajax({
    url: "/ajax_json_echo/",
    timeout: 500,
    error: function(jqXHR, textStatus, errorThrown) {
        alert(textStatus); // this will be "timeout"
    }
});

Here it is on jsfiddle.

For MySQL 5.0.3 and higher, you can use BIT. The manual says:

As of MySQL 5.0.3, the BIT data type is used to store bit-field values. A type of BIT(M) enables storage of M-bit values. M can range from 1 to 64.

Otherwise, according to the MySQL manual you can use BOOL or BOOLEAN, which are at the moment aliases of tinyint(1):

Bool, Boolean: These types are synonyms for TINYINT(1). A value of zero is considered false. Non-zero values are considered true.

MySQL also states that:

We intend to implement full boolean type handling, in accordance with standard SQL, in a future MySQL release.

You can create an auxiliar form using jQuery with the content of another form and then add thath form other params so you only have to serialize it in the ajax call.

function createInput(name,value){
    return $('<input>').attr({
        name: name,
        value: value
    });
}
$form = $("<form></form>");
$form.append($("#your_form input").clone());
$form.append(createInput('input_name', 'input_value'));
$form.append(createInput('input_name_2', 'input_value_2'));
....

$.ajax({
    type : 'POST',
    url : 'url',
    data : $form.serialize()
}

the easiest thing to do is this:

$str = 'TRUE';

$boolean = strtolower($str) == 'true' ? true : false;

var_dump($boolean);

Doing it this way, you can loop through a series of 'true', 'TRUE', 'false' or 'FALSE' and get the string value to a boolean.

Use below if you need to empty Angular 2+ FormArray.

public emptyFormArray(formArray:FormArray) {

        formArray.removeAt(i);
    }
}

I'm not 100% sure that I understand your question, so tell me if I'm wrong.

If I got it right, you are reading jbytes that are technically signed chars, but really pixel values ranging from 0 to 255, and you're wondering how you should handle them without corrupting the values in the process.

Then, you should do the following:

• convert jbytes to unsigned char before doing anything else, this will definetly restore the pixel values you are trying to manipulate

• use a larger signed integer type, such as int while doing intermediate calculations, this to make sure that over- and underflows can be detected and dealt with (in particular, not casting to a signed type could force to compiler to promote every type to an unsigned type in which case you wouldn't be able to detect underflows later on)

• when assigning back to a jbyte, you'll want to clamp your value to the 0-255 range, convert to unsigned char and then convert again to signed char: I'm not certain the first conversion is strictly necessary, but you just can't be wrong if you do both

For example:

inline int fromJByte(jbyte pixel) {
    // cast to unsigned char re-interprets values as 0-255
    // cast to int will make intermediate calculations safer
    return static_cast<int>(static_cast<unsigned char>(pixel));
}

inline jbyte fromInt(int pixel) {
    if(pixel < 0)
        pixel = 0;

    if(pixel > 255)
        pixel = 255;

    return static_cast<jbyte>(static_cast<unsigned char>(pixel));
}

jbyte in = ...
int intermediate = fromJByte(in) + 30;
jbyte out = fromInt(intermediate);

Here a one-file solution (based on elegant answer by @Marcin:

#include <iostream>

#define ENUM_TXT \
X(Red) \
X(Green) \
X(Blue) \
X(Cyan) \
X(Yellow) \
X(Magenta) \

enum Colours {
#   define X(a) a,
ENUM_TXT
#   undef X
    ColoursCount
};

char const* const colours_str[] = {
#   define X(a) #a,
ENUM_TXT
#   undef X
    0
};

std::ostream& operator<<(std::ostream& os, enum Colours c)
{
    if (c >= ColoursCount || c < 0) return os << "???";
    return os << colours_str[c] << std::endl;
}

int main()
{
    std::cout << Red << Blue << Green << Cyan << Yellow << Magenta << std::endl;
}

Simplest solution:

substr('299123456',-6,6)

You can use the environment variable $HOME for that.

I came through this error. The problem was The developer identity and Mobile Provisioning Profile mismatch.

Delete keychain certificates and fresh install matching provisioning profile and developer certificate fixed the problem.

Whenever I find myself at your place, I use the following command line:

git log -S "<words/phrases i am trying to find>" --all --oneline  --graph

Explanation:

1. git log - Need I write more here; it shows the logs in chronological order.
2. -S "<words/phrases i am trying to find>" - It shows all those Git commits where any file (added/modified/deleted) has the words/phrases I am trying to find without '<>' symbols.
3. --all - To enforce and search across all the branches.
4. --oneline - It compresses the Git log in one line.
5. --graph - It creates the graph of chronologically ordered commits.

In my case, I was trying to parse an empty JSON:

JSON.parse(stringifiedJSON);

In other words, what happened was the following:

JSON.parse("");

I think (from experimenting - MSDN is unhelpful here) that there is no direct way of doing this. Setting Criteria1 to an Array is equivalent to using the tick boxes in the dropdown - as you say it will only filter a list based on items that match one of those in the array.

Interestingly, if you have the literal values "<>A" and "<>B" in the list and filter on these the macro recorder comes up with

Range.AutoFilter Field:=1, Criteria1:="=<>A", Operator:=xlOr, Criteria2:="=<>B"

which works. But if you then have the literal value "<>C" as well and you filter for all three (using tick boxes) while recording a macro, the macro recorder replicates precisely your code which then fails with an error. I guess I'd call that a bug - there are filters you can do using the UI which you can't do with VBA.

Anyway, back to your problem. It is possible to filter values not equal to some criteria, but only up to two values which doesn't work for you:

Range("$A$1:$A$9").AutoFilter Field:=1, Criteria1:="<>A", Criteria2:="<>B", Operator:=xlAnd

There are a couple of workarounds possible depending on the exact problem:

1. Use a "helper column" with a formula in column B and then filter on that - e.g. =ISNUMBER(A2) or =NOT(A2="A", A2="B", A2="C") then filter on TRUE
2. If you can't add a column, use autofilter with Criteria1:=">-65535" (or a suitable number lower than any you expect) which will filter out non-numeric values - assuming this is what you want
3. Write a VBA sub to hide rows (not exactly the same as an autofilter but it may suffice depending on your needs).

For example:

Public Sub hideABCRows(rangeToFilter As Range)
  Dim oCurrentCell As Range
  On Error GoTo errHandler

  Application.ScreenUpdating = False
  For Each oCurrentCell In rangeToFilter.Cells
    If oCurrentCell.Value = "A" Or oCurrentCell.Value = "B" Or oCurrentCell.Value = "C" Then
      oCurrentCell.EntireRow.Hidden = True
    End If
  Next oCurrentCell

  Application.ScreenUpdating = True
  Exit Sub

errHandler:
    Application.ScreenUpdating = True
End Sub

Yet another way to do this:

(Get-Date).AddDays(-1).Date.AddHours(22)

I was trying to @Autowire a Spring-managed service into my Deserializer. Somebody tipped me off to Jackson using the new operator when invoking the serializers/deserializers. This meant no auto-wiring of Jackson's instance of my Deserializer. Here's how I was able to @Autowire my service class into my Deserializer:

context.xml

<mvc:annotation-driven>
  <mvc:message-converters>
    <bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
      <property name="objectMapper" ref="objectMapper" />
    </bean>
  </mvc:message-converters>
</mvc>
<bean id="objectMapper" class="org.springframework.http.converter.json.Jackson2ObjectMapperFactoryBean">
    <!-- Add deserializers that require autowiring -->
    <property name="deserializersByType">
        <map key-type="java.lang.Class">
            <entry key="com.acme.Anchor">
                <bean class="com.acme.AnchorDeserializer" />
            </entry>
        </map>
    </property>
</bean>

Now that my Deserializer is a Spring-managed bean, auto-wiring works!

AnchorDeserializer.java

public class AnchorDeserializer extends JsonDeserializer<Anchor> {
    @Autowired
    private AnchorService anchorService;
    public Anchor deserialize(JsonParser parser, DeserializationContext context)
             throws IOException, JsonProcessingException {
        // Do stuff
    }
}

AnchorService.java

@Service
public class AnchorService {}

Update: While my original answer worked for me back when I wrote this, @xi.lin's response is exactly what is needed. Nice find!

I have found a variety of runtimes including Visual Studio(VS) versions are available at http://scn.sap.com/docs/DOC-7824

If you don't wish to mess with IFS (perhaps for the code within the loop) this might help.

If know that your string will not have whitespace, you can substitute the ';' with a space and use the for/in construct:

#local str
for str in ${STR//;/ } ; do 
   echo "+ \"$str\""
done

But if you might have whitespace, then for this approach you will need to use a temp variable to hold the "rest" like this:

#local str rest
rest=$STR
while [ -n "$rest" ] ; do
   str=${rest%%;*}  # Everything up to the first ';'
   # Trim up to the first ';' -- and handle final case, too.
   [ "$rest" = "${rest/;/}" ] && rest= || rest=${rest#*;}
   echo "+ \"$str\""
done

I understand this question has been answered but perhaps this might be useful to someone...

If you wish to copy the data into a separate cv::Mat object you could use a function similar to this:

void ExtractROI(Mat& inImage, Mat& outImage, Rect roi){
    /* Create the image */
    outImage = Mat(roi.height, roi.width, inImage.type(), Scalar(0));

    /* Populate the image */
    for (int i = roi.y; i < (roi.y+roi.height); i++){
        uchar* inP = inImage.ptr<uchar>(i);
        uchar* outP = outImage.ptr<uchar>(i-roi.y);
        for (int j = roi.x; j < (roi.x+roi.width); j++){
            outP[j-roi.x] = inP[j];
        }
    }
}

It would be important to note that this would only function properly on single channel images.

rx = r'\b(?<=\w){0}\b(?!\w)'.format(TEXTO)

Plain Javascript:

window.location = "#elementId"

expr is used instead of [ rather than inside it, and variables are only expanded inside double quotes, so try this:

if expr match "$LIST" "$SOURCE"; then

But I'm not really clear what SOURCE is supposed to represent.

It looks like your code will read in a pattern from standard input, and exit if it matches a database alias, otherwise it will echo "ok". Is that what you want?

In SQL, this problem could be solved by several methods:

select * from df1 where exists (select * from df2 where df2.user_id = df1.user_id)
union all
select * from df2 where exists (select * from df1 where df1.user_id = df2.user_id)

or join and then unpivot (possible in SQL server)

select
    df1.user_id,
    c.rating
from df1
    inner join df2 on df2.user_i = df1.user_id
    outer apply (
        select df1.rating union all
        select df2.rating
    ) as c

Second one could be written in pandas with something like:

>>> df1 = pd.DataFrame({"user_id":[1,2,3], "rating":[10, 15, 20]})
>>> df2 = pd.DataFrame({"user_id":[3,4,5], "rating":[30, 35, 40]})
>>>
>>> df4 = df[['user_id', 'rating_1']].rename(columns={'rating_1':'rating'})
>>> df = pd.merge(df1, df2, on='user_id', suffixes=['_1', '_2'])
>>> df3 = df[['user_id', 'rating_1']].rename(columns={'rating_1':'rating'})
>>> df4 = df[['user_id', 'rating_2']].rename(columns={'rating_2':'rating'})
>>> pd.concat([df3, df4], axis=0)
   user_id  rating
0        3      20
0        3      30

put export { Home }; at the end of the Home.js file

swift 5 version:

By using default inbuilt color:

1. button.setTitleColor(UIColor.green, for: .normal)

OR

You can use your custom color by using RGB method:

2. button.setTitleColor(UIColor(displayP3Red: 0.0/255.0, green: 180.0/255.0, blue: 2.0/255.0, alpha: 1.0), for: .normal)

I don't like adding new package into my project just to handle this simple task.

And also, I try my best to avoid RECURSIVE algorithm.... since, for most cases it is slower compared to non Recursive one.

So I made a function to get all the folder content (and its sub folder).... NON-Recursively

var getDirectoryContent = function(dirPath) {
    /* 
        get list of files and directories from given dirPath and all it's sub directories
        NON RECURSIVE ALGORITHM
        By. Dreamsavior
    */
    var RESULT = {'files':[], 'dirs':[]};

    var fs = fs||require('fs');
    if (Boolean(dirPath) == false) {
        return RESULT;
    }
    if (fs.existsSync(dirPath) == false) {
        console.warn("Path does not exist : ", dirPath);
        return RESULT;
    }

    var directoryList = []
    var DIRECTORY_SEPARATOR = "\\";
    if (dirPath[dirPath.length -1] !== DIRECTORY_SEPARATOR) dirPath = dirPath+DIRECTORY_SEPARATOR;

    directoryList.push(dirPath); // initial

    while (directoryList.length > 0) {
        var thisDir  = directoryList.shift(); 
        if (Boolean(fs.existsSync(thisDir) && fs.lstatSync(thisDir).isDirectory()) == false) continue;

        var thisDirContent = fs.readdirSync(thisDir);
        while (thisDirContent.length > 0) { 
            var thisFile  = thisDirContent.shift(); 
            var objPath = thisDir+thisFile

            if (fs.existsSync(objPath) == false) continue;
            if (fs.lstatSync(objPath).isDirectory()) { // is a directory
                let thisDirPath = objPath+DIRECTORY_SEPARATOR; 
                directoryList.push(thisDirPath);
                RESULT['dirs'].push(thisDirPath);

            } else  { // is a file
                RESULT['files'].push(objPath); 

            } 
        } 

    }
    return RESULT;
}

the only drawback of this function is that this is Synchronous function... You have been warned ;)

String[] result = input.split("(?!^)");

What this does is split the input String on all empty Strings that are not preceded by the beginning of the String.

You can also try this. Credits to the original author who has since removed the script

$var[62] = 'Casio';
$var[63] = 'HTC';
$var[64] = 'Motorola';
$var[65] = 'Samsung';
$var[66] = 'NEC';

$result = count($var);

for ($i=0;$i<$result;$i++)
{    
    $ausg = stristr($text, $var[$i]);    
    if(strlen($ausg)>0)
    {
        header("location: $mobile");
        exit;
    }

}
?>

Just edit the $mobile = "http://www.stepforth.mobi";

Allocate memory before using the pointer. If you don't allocate memory *point = 12 is undefined behavior.

int *fun()
{
    int *point = malloc(sizeof *point); /* Mandatory. */
    *point=12;  
    return point;
}

Also your printf is wrong. You need to dereference (*) the pointer.

printf("%d", *ptr);
             ^

For initial array, better use object instead of array, as then you won't be worrying about the indexes and it will be much more clear what is what:

const initialArr = [{
    color: "blue",
    text: "text1"
}, {
    color: "red",
    text: "text2"
}];

For actual mapping, use JS Array map instead of for loop - for loop should be used in cases when there's no actual array defined, like displaying something a certain number of times:

onPress = () => {
    ...
};

renderButtons() {
    return initialArr.map((item) => {
        return (
            <Button 
                style={{ borderColor: item.color }}
                onPress={this.onPress}
            >
                {item.text}
            </Button>
        );
    });
}

...

render() {
    return (
        <View style={...}>
            {
                this.renderButtons()
            }
        </View>
    )
}

I moved the mapping to separate function outside of render method for more readable code. There are many other ways to loop through list of elements in react native, and which way you'll use depends on what do you need to do. Most of these ways are covered in this article about React JSX loops, and although it's using React examples, everything from it can be used in React Native. Please check it out if you're interested in this topic!

Also, not on the topic on the looping, but as you're already using the array syntax for defining the onPress function, there's no need to bind it again. This, again, applies only if the function is defined using this syntax within the component, as the arrow syntax auto binds the function.

I realize this has been answered, but I used a different approach and thought it might be worth sharing. Also, I feel like my approach might produce unwanted overhead. However, I'm not able to observer or calculate anything happening that is that bad under the loads we observe. I was looking for any useful feedback on this approach.

The problem with working with dynamics is that you can't attach any functions to the dynamic object directly. You have to use something that can figure out the assignments that you don't want to figure out every time.

When planning this simple solution, I looked at what the valid intermediaries are when attempting to retype similar objects. I found that a binary array, string (xml, json) or hard coding a conversion (IConvertable) were the usual approaches. I don't want to get into binary conversions due to a code maintainability factor and laziness.

My theory was that Newtonsoft could do this by using a string intermediary.

As a downside, I am fairly certain that when converting the string to an object, that it would use reflection by searching the current assembly for an object with matching properties, create the type, then instantiate the properties, which would require more reflection. If true, all of this can be considered avoidable overhead.

C#:

//This lives in a helper class
public static ConvertDynamic<T>(dynamic data)
{
     return Newtonsoft.Json.JsonConvert.DeserializeObject<T>(Newtonsoft.Json.JsonConvert.SerializeObject(data));
}

//Same helper, but in an extension class (public static class),
//but could be in a base class also.
public static ToModelList<T>(this List<dynamic> list)
{
    List<T> retList = new List<T>();
    foreach(dynamic d in list)
    {
        retList.Add(ConvertDynamic<T>(d));
    }
}

With that said, this fits another utility I've put together that lets me make any object into a dynamic. I know I had to use reflection to do that correctly:

public static dynamic ToDynamic(this object value)
{
    IDictionary<string, object> expando = new ExpandoObject();

    foreach (PropertyDescriptor property in TypeDescriptor.GetProperties(value.GetType()))
        expando.Add(property.Name, property.GetValue(value));

    return expando as ExpandoObject;
}

I had to offer that function. An arbitrary object assigned to a dynamic typed variable cannot be converted to an IDictionary, and will break the ConvertDynamic function. For this function chain to be used it has to be provided a dynamic of System.Dynamic.ExpandoObject, or IDictionary<string, object>.

Use the built-in localized formats

If this is for showing a time of day to a user, then in at least 19 out of 20 you don’t need to care about kk, HH nor hh. I suggest that you use something like this:

    DateTimeFormatter defaultTimeFormatter
            = DateTimeFormatter.ofLocalizedTime(FormatStyle.SHORT);
    System.out.format("%s: %s%n",
            Locale.getDefault(), LocalTime.MIN.format(defaultTimeFormatter));

The point is that it gives different output in different default locales. For example:

en_SS: 12:00 AM
fr_BL: 00:00
ps_AF: 0:00
es_CO: 12:00 a.m.

The localized formats have been designed to conform with the expectations of different cultures. So they generally give the user a better experience and they save you of writing a format pattern string, which is always error-prone.

I furthermore suggest that you don’t use SimpleDateFormat. That class is notoriously troublesome and fortunately long outdated. Instead I use java.time, the modern Java date and time API. It is so much nicer to work with.

Four pattern letters for hour: H, h, k and K

Of course if you need to parse a string with a specified format, and also if you have a very specific formatting requirement, it’s good to use a format pattern string. There are actually four different pattern letters to choose from for hour (quoted from the documentation):

  Symbol  Meaning                     Presentation      Examples
  ------  -------                     ------------      -------
   h       clock-hour-of-am-pm (1-12)  number            12
   K       hour-of-am-pm (0-11)        number            0
   k       clock-hour-of-day (1-24)    number            24
   H       hour-of-day (0-23)          number            0

In practice H and h are used. As far as I know k and K are not (they may just have been included for the sake of completeness). But let’s just see them all in action:

    DateTimeFormatter timeFormatter
            = DateTimeFormatter.ofPattern("hh:mm a  HH:mm  kk:mm  KK:mm a", Locale.ENGLISH);
    System.out.println(LocalTime.of(0, 0).format(timeFormatter));
    System.out.println(LocalTime.of(1, 15).format(timeFormatter));
    System.out.println(LocalTime.of(11, 25).format(timeFormatter));
    System.out.println(LocalTime.of(12, 35).format(timeFormatter));
    System.out.println(LocalTime.of(13, 40).format(timeFormatter));

12:00 AM  00:00  24:00  00:00 AM
01:15 AM  01:15  01:15  01:15 AM
11:25 AM  11:25  11:25  11:25 AM
12:35 PM  12:35  12:35  00:35 PM
01:40 PM  13:40  13:40  01:40 PM

If you don’t want the leading zero, just specify one pattern letter, that is h instead of hh or H instead of HH. It will still accept two digits when parsing, and if a number to be printed is greater than 9, two digits will still be printed.

Could not get IE9 to center the dialog.

Fixed it by adding this to the css:

.ui-dialog {
    left:1%;
    right:1%;
}

Percent doesn't matter. Any small number worked.

You can also use "shouldReceiveTouch" method of UIGestureRecognizer

- (BOOL)gestureRecognizer:(UIGestureRecognizer *)gestureRecognizer shouldReceiveTouch:     (UITouch *)touch {
     UIView *view = touch.view; 
     NSLog(@"%d", view.tag); 
}    

Dont forget to set delegate of your gesture recognizer.

I experienced a similar problem and doing width:100%; solved it for me. I came to this solution after trying an answer in this question and realizing that the very nature of an <iframe> will make these javascript measurement tools inaccurate without using some complex function. Doing 100% is a simple way to take care of it in an iframe. I don't know about your issue since I'm not sure of what HTML elements you are manipulating.

Here I will show you that how you can make a phone call from your activity. To make a call you have to put down this code in your app.

try {
    Intent my_callIntent = new Intent(Intent.ACTION_CALL);
    my_callIntent.setData(Uri.parse("tel:"+phn_no));
    //here the word 'tel' is important for making a call...
    startActivity(my_callIntent);
} catch (ActivityNotFoundException e) {
    Toast.makeText(getApplicationContext(), "Error in your phone call"+e.getMessage(), Toast.LENGTH_LONG).show();
}

The RFC for the HTTP Header Field X-Frame-Options states that the "ALLOW-FROM" field in the X-Frame-Options header value can only contain one domain. Multiple domains are not allowed.

The RFC suggests a work around for this problem. The solution is to specify the domain name as a url parameter in the iframe src url. The server that hosts the iframe src url can then check the domain name given in the url parameters. If the domain name matches a list of valid domain names, then the server can send the X-Frame-Options header with the value: "ALLOW-FROM domain-name", where domain name is the name of the domain that is trying to embed the remote content. If the domain name is not given or is not valid, then the X-Frame-Options header can be sent with the value: "deny".

request.getParameterValues("select2") returns an array of all submitted values.

For others that stumble on this, you can also use ejs params/props in conditional statements:

recipes.js File:

app.get("/recipes", function(req, res) {
    res.render("recipes.ejs", {
        recipes: recipes
    });
});

recipes.ejs File:

<%if (recipes.length > 0) { %>
// Do something with more than 1 recipe
<% } %>

If you're having this problem with Spring Boot 1.4.x and up, you might be able to use @OverrideAutoConfiguration(enabled=true) to solve the problem.

The artifact has been moved from net.sourceforge.findbugs to

Well in pure javascript my thinking is that you would first have to collate them inside a collection.

var divs = document.getElementsByTagName("div");
//divs now contain each and every div element on the page
var selectionDiv = document.getElementById("MySecondDiv");

So basically with selectionDiv iterate through the collection to find its index, and then obviously -1 = previous +1 = next within bounds

for(var i = 0; i < divs.length;i++)
{
   if(divs[i] == selectionDiv)
   {
     var previous = divs[i - 1];
     var next = divs[i + 1];
   }
}

Please be aware though as I say that extra logic would be required to check that you are within the bounds i.e. you are not at the end or start of the collection.

This also will mean that say you have a div which has a child div nested. The next div would not be a sibling but a child, So if you only want siblings on the same level as the target div then definately use nextSibling checking the tagName property.

To send to both remote with one command, you can create a alias for it:

git config alias.pushall '!git push origin devel && git push github devel'

With this, when you use the command git pushall, it will update both repositories.

One trick that works well is to attach a debugger and then quit the debugger.

On XP or Windows 2003 you can do this using ntsd that ships out of the box:

ntsd -pn myapp.exe

ntsd will open up a new window. Just type 'q' in the window to quit the debugger and take out the process.

I've known this to work even when task manager doesn't seem able to kill a process.

Unfortunately ntsd was removed from Vista and you have to install the (free) debbugging tools for windows to get a suitable debugger.

My issue was resolved After adding
sessionFactory.setPackagesToScan( new String[] { "com.springhibernate.model" }); Tested this Functionality in spring boot latest version 2.1.2.

Full Method:

 @Bean( name="sessionFactoryConfig")
    public LocalSessionFactoryBean sessionFactoryConfig() {

        LocalSessionFactoryBean sessionFactory = new LocalSessionFactoryBean();

        sessionFactory.setDataSource(dataSourceConfig());
        sessionFactory.setPackagesToScan(
                new String[] { "com.springhibernate.model" });

        sessionFactory.setHibernateProperties(hibernatePropertiesConfig());

        return sessionFactory;
    }

So easy:

git diff --name-only

ng-init is a directive that can be placed inside div's, span's, whatever, whereas onload is an attribute specific to the ng-include directive that functions as an ng-init. To see what I mean try something like:

<span onload="a = 1">{{ a }}</span>
<span ng-init="b = 2">{{ b }}</span>

You'll see that only the second one shows up.

An isolated scope is a scope which does not prototypically inherit from its parent scope. In laymen's terms if you have a widget that doesn't need to read and write to the parent scope arbitrarily then you use an isolate scope on the widget so that the widget and widget container can freely use their scopes without overriding each other's properties.

A simpler OS-independent solution:

Go ahead and attempt to create the actual directory; if there is an issue or the name is invalid, the OS will automatically complain and the code will throw.

public static class PathHelper
{
    public static void ValidatePath(string path)
    {
        if (!Directory.Exists(path))
            Directory.CreateDirectory(path).Delete();
    }
}

Usage:

try
{
    PathHelper.ValidatePath(path);
}
catch(Exception e)
{
    // handle exception
}

Directory.CreateDirectory() will automatically throw in all of the following situations:

System.IO.IOException:
The directory specified by path is a file. -or- The network name is not known.

System.UnauthorizedAccessException:
The caller does not have the required permission.

System.ArgumentException:
path is a zero-length string, contains only white space, or contains one or more invalid characters. You can query for invalid characters by using the System.IO.Path.GetInvalidPathChars method. -or- path is prefixed with, or contains, only a colon character (:).

System.ArgumentNullException:
path is null.

System.IO.PathTooLongException:
The specified path, file name, or both exceed the system-defined maximum length.

System.IO.DirectoryNotFoundException:
The specified path is invalid (for example, it is on an unmapped drive).

System.NotSupportedException:
path contains a colon character (:) that is not part of a drive label ("C:").

The safest way to pass credentials to curl is to be prompted to insert them. This is what happens when passing the username as suggested earlier (-u USERNAME).

But what if you can't pass the username that way? For instance the username might need to be part of the url and only the password be part of a json payload.

tl;dr: This is how to use curl safely in this case:

read -p "Username: " U; read -sp "Password: " P; curl --request POST -d "{\"password\":\"${P}\"}" https://example.com/login/${U}; unset P U

read will prompt for both username and password from the command line, and store the submitted values in two variables that can be references in subsequent commands and finally unset.

I'm gonna elaborate on why the other solutions are not ideal.

Why are environment variables unsafe

1. Access and exposure mode of the content of an environment variable, can not be tracked (ps -eww ) since the environment is implicitly available to a process
2. Often apps grab the whole environment and log it for debugging or monitoring purposes (sometimes on log files plaintext on disk, especially after an app crashes)
3. Environment variables are passed down to child processes (therefore breaking the principle of least privilege)
4. Maintaining them is an issue: new engineers don't know they are there, and are not aware of requirements around them - e.g., not to pass them to sub-processes - since they're not enforced or documented.

Why is it unsafe to type it into a command on the command line directly Because your secret then ends up being visible by any other user running ps -aux since that lists commands submitted for each currently running process. Also because your secrte then ends up in the bash history (once the shell terminates).

Why is it unsafe to include it in a local file Strict POSIX access restriction on the file can mitigate the risk in this scenario. However, it is still a file on your file system, unencrypted at rest.

You can try this

ISNUMERIC (Transact-SQL)

ISNUMERIC returns 1 when the input expression evaluates to a valid numeric data type; otherwise it returns 0.

DECLARE @Table TABLE(
        Col VARCHAR(50)
)

INSERT INTO @Table SELECT 'ABC' 
INSERT INTO @Table SELECT 'Italy' 
INSERT INTO @Table SELECT 'Apple' 
INSERT INTO @Table SELECT '234.62' 
INSERT INTO @Table SELECT '2:234:43:22' 
INSERT INTO @Table SELECT 'France' 
INSERT INTO @Table SELECT '6435.23'
INSERT INTO @Table SELECT '2' 
INSERT INTO @Table SELECT 'Lions'

SELECT  *
FROM    @Table
WHERE   ISNUMERIC(Col) = 1

This works for MySQL and is really just an implicit transaction but it should go something like this:

UPDATE Table1 t1, Table2 t2 SET 
t2.field = t2.field+2,
t1.field = t1.field+2

WHERE t1.id = t2.foreign_id and t2.id = '123414'

if you are doing updates to multi tables that require multi statements… which is likely possible if you update one, then another based on other conditions… you should use a transaction. 

The accepted answer is short and sweet, but here is an alternate syntax allowing to provide a separator in Python 3.x.

print(*3*('-',), sep='_')

I have strong working solution.

in layoutSubviews:

    _title.frame = CGRect(x: 0, y: 0, width: bounds.width, height: 0)
    _title.sizeToFit()
    _title.frame.size = _title.bounds.size

in text setter:

    _title.text = newValue
    setNeedsLayout()

UPD. of course with this UILabel settings:

    _title.lineBreakMode = .ByWordWrapping
    _title.numberOfLines = 0

In your route configuration you typically define a route like,

.when('somewhere/:param1/:param2')

You can then either get the route in the resolve object by using $route.current.params or in a controller, $routeParams. In either case the parameters is extracted using the mapping of the route, so param1 can be accessed by $routeParams.param1 in the controller.

Edit: Also note that the mapping has to be exact

/some/folder/:param1

Will only match a single parameter.

/some/folder/:param1/:param2 

Will only match two parameters.

This is a bit different then most dynamic server side routes. For example NodeJS (Express) route mapping where you can supply only a single route with X number of parameters.

A reference is semantically the following:

T& <=> *(T * const)

const T& <=> *(T const * const)

T&& <=> [no C equivalent] (C++11)

As with other answers, the following from the C++ FAQ is the one-line answer: references when possible, pointers when needed.

An advantage over pointers is that you need explicit casting in order to pass NULL. It's still possible, though. Of the compilers I've tested, none emit a warning for the following:

int* p() {
    return 0;
}
void x(int& y) {
  y = 1;
}
int main() {
   x(*p());
}

Simple answer: You can stop a thread INTERNALLY in one of two common ways:

• The run method hits a return subroutine.
• Run method finishes, and returns implicitly.

You can also stop threads EXTERNALLY:

• Call system.exit (this kills your entire process)
• Call the thread object's interrupt() method *
• See if the thread has an implemented method that sounds like it would work (like kill() or stop())

*: The expectation is that this is supposed to stop a thread. However, what the thread actually does when this happens is entirely up to what the developer wrote when they created the thread implementation.

A common pattern you see with run method implementations is a while(boolean){}, where the boolean is typically something named isRunning, it's a member variable of its thread class, it's volatile, and typically accessible by other threads by a setter method of sorts, e.g. kill() { isRunnable=false; }. These subroutines are nice because they allow the thread to release any resources it holds before terminating.

Of course it's possible to create a foreign key relationship to a compound (more than one column) primary key. You didn't show us the statement you're using to try and create that relationship - it should be something like:

ALTER TABLE dbo.Content
   ADD CONSTRAINT FK_Content_Libraries
   FOREIGN KEY(LibraryID, Application)
   REFERENCES dbo.Libraries(ID, Application)

Is that what you're using?? If (ID, Application) is indeed the primary key on dbo.Libraries, this statement should definitely work.

Luk: just to check - can you run this statement in your database and report back what the output is??

SELECT
    tc.TABLE_NAME,
    tc.CONSTRAINT_NAME, 
    ccu.COLUMN_NAME
FROM 
    INFORMATION_SCHEMA.TABLE_CONSTRAINTS tc
INNER JOIN 
    INFORMATION_SCHEMA.CONSTRAINT_COLUMN_USAGE ccu 
      ON ccu.TABLE_NAME = tc.TABLE_NAME AND ccu.CONSTRAINT_NAME = tc.CONSTRAINT_NAME
WHERE
    tc.TABLE_NAME IN ('Libraries', 'Content')

You probably want to have LI rather than the UL have the background-color:

.selected li {
  background-color: red;
}

Then you want to have a dynamic class for the UL:

<ul ng-repeat="vote in votes" ng-click="setSelected()" class="{{selected}}">

Now you need to update the $scope.selected when clicking the row:

$scope.setSelected = function() {
   console.log("show", arguments, this);
   this.selected = 'selected';
}

and then un-select the previously highlighted row:

$scope.setSelected = function() {
   // console.log("show", arguments, this);
   if ($scope.lastSelected) {
     $scope.lastSelected.selected = '';
   }
   this.selected = 'selected';
   $scope.lastSelected = this;
}

You could add in your code a call system with the new definition:

sprintf(newdef,"export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:%s:%s",ld1,ld2);
system(newdef);

But, I don't know it that is the rigth solution but it works.

You can use a2enmod or a2dismod to enable/disable modules by name.

From terminal, run: sudo a2enmod php5 to enable PHP5 (or some other module), then sudo service apache2 reload to reload the Apache2 configuration.

The best way of doing it is to just trigger Bootstrap's click event with a hover. This way, it should still remain touch device friendly.

$('.dropdown').hover(function(){ 
  $('.dropdown-toggle', this).trigger('click'); 
});

pythonpy is a tool that provides easy access to many of the features from awk and sed, but using python syntax:

I use automatic tasks run on folder (should work VSCode >=1.30) in .vscode/tasks.json

{

If this still not work on project folder open try Ctrl+shift+P and Tasks: Manage Automatic Tasks in Folder and choose "Allow Automatic Tasks in folder" on main project folder or running folder.

Currently, no, not without resorting to trickery. borders on elements are supposed to run the entire length of whatever side of the element box they apply to.

You could use moment.js with Postman to give you that timestamp format.

You can add this to the pre-request script:

const moment = require('moment');
pm.globals.set("today", moment().format("MM/DD/YYYY"));

Then reference {{today}} where ever you need it.

If you add this to the Collection Level Pre-request Script, it will be run for each request in the Collection. Rather than needing to add it to all the requests individually.

For more information about using moment in Postman, I wrote a short blog post: https://dannydainton.com/2018/05/21/hold-on-wait-a-moment/

We can pass string value to main method as argument without using commandline argument concept in java through Netbean

 package MainClass;
 import java.util.Scanner;
 public class CmdLineArgDemo {

static{
 Scanner readData = new Scanner(System.in);   
 System.out.println("Enter any string :");
 String str = readData.nextLine();
 String [] str1 = str.split(" ");
 // System.out.println(str1.length);
 CmdLineArgDemo.main(str1);
}  

   public static void main(String [] args){
      for(int i = 0 ; i<args.length;i++) {
        System.out.print(args[i]+" ");
      }
    }
  }

Output

Enter any string :

You can use IETester (http://www.my-debugbar.com/wiki/IETester/HomePage)

To suppress the page number on the first page, add \thispagestyle{empty} after the \maketitle command.

The second page of the document will then be numbered "2". If you want this page to be numbered "1", you can add \pagenumbering{arabic} after the \clearpage command, and this will reset the page number.

Here's a complete minimal example:

\documentclass[notitlepage]{article}

\title{My Report}
\author{My Name}

\begin{document}
\maketitle
\thispagestyle{empty}

\begin{abstract}
\ldots
\end{abstract}

\clearpage
\pagenumbering{arabic} 

\section{First Section}
\ldots

\end{document}

I had the same Error and my Problem was, that I had my php-file in my encrypted home-directory. And I run my fpm with the www-data user and this user can't read the php-files even if the permissions on the file were right. The solutioin was that I run fpm with the user who owns the home-directory. This can be changed in folowing file:

/etc/php5/fpm/pool.d/www.conf

hope this will help you :)

I am posting this answer so the topmost answer (when sorted by activity) is not one that is just plain wrong.

What is a Stacktrace?

A stacktrace is a very helpful debugging tool. It shows the call stack (meaning, the stack of functions that were called up to that point) at the time an uncaught exception was thrown (or the time the stacktrace was generated manually). This is very useful because it doesn't only show you where the error happened, but also how the program ended up in that place of the code. This leads over to the next question:

What is an Exception?

An Exception is what the runtime environment uses to tell you that an error occurred. Popular examples are NullPointerException, IndexOutOfBoundsException or ArithmeticException. Each of these are caused when you try to do something that is not possible. For example, a NullPointerException will be thrown when you try to dereference a Null-object:

Object a = null;
a.toString();                 //this line throws a NullPointerException

Object[] b = new Object[5];
System.out.println(b[10]);    //this line throws an IndexOutOfBoundsException,
                              //because b is only 5 elements long
int ia = 5;
int ib = 0;
ia = ia/ib;                   //this line throws an  ArithmeticException with the 
                              //message "/ by 0", because you are trying to
                              //divide by 0, which is not possible.

How should I deal with Stacktraces/Exceptions?

At first, find out what is causing the Exception. Try googleing the name of the exception to find out, what is the cause of that exception. Most of the time it will be caused by incorrect code. In the given examples above, all of the exceptions are caused by incorrect code. So for the NullPointerException example you could make sure that a is never null at that time. You could, for example, initialise a or include a check like this one:

if (a!=null) {
    a.toString();
}

This way, the offending line is not executed if a==null. Same goes for the other examples.

Sometimes you can't make sure that you don't get an exception. For example, if you are using a network connection in your program, you cannot stop the computer from loosing it's internet connection (e.g. you can't stop the user from disconnecting the computer's network connection). In this case the network library will probably throw an exception. Now you should catch the exception and handle it. This means, in the example with the network connection, you should try to reopen the connection or notify the user or something like that. Also, whenever you use catch, always catch only the exception you want to catch, do not use broad catch statements like catch (Exception e) that would catch all exceptions. This is very important, because otherwise you might accidentally catch the wrong exception and react in the wrong way.

try {
    Socket x = new Socket("1.1.1.1", 6789);
    x.getInputStream().read()
} catch (IOException e) {
    System.err.println("Connection could not be established, please try again later!")
}

Why should I not use catch (Exception e)?

Let's use a small example to show why you should not just catch all exceptions:

int mult(Integer a,Integer b) {
    try {
        int result = a/b
        return result;
    } catch (Exception e) {
        System.err.println("Error: Division by zero!");
        return 0;
    }
}

What this code is trying to do is to catch the ArithmeticException caused by a possible division by 0. But it also catches a possible NullPointerException that is thrown if a or b are null. This means, you might get a NullPointerException but you'll treat it as an ArithmeticException and probably do the wrong thing. In the best case you still miss that there was a NullPointerException. Stuff like that makes debugging much harder, so don't do that.

TLDR

1. Figure out what is the cause of the exception and fix it, so that it doesn't throw the exception at all.

2. If 1. is not possible, catch the specific exception and handle it.

   • Never just add a try/catch and then just ignore the exception! Don't do that!
   • Never use catch (Exception e), always catch specific Exceptions. That will save you a lot of headaches.

In plain English: Assume you can do 3 things:

1. Take one apple
2. Write down tally marks
3. Count tally marks

You have a lot of apples in front of you on a table and you want to know how many apples there are.

start
  Is the table empty?
  yes: Count the tally marks and cheer like it's your birthday!
  no:  Take 1 apple and put it aside
       Write down a tally mark
       goto start

The process of repeating the same thing till you are done is called recursion.

I hope this is the "plain english" answer you are looking for!

We can break both a $(selector).each() loop and a $.each() loop at a particular iteration by making the callback function return false. Returning non-false is the same as a continue statement in a for loop; it will skip immediately to the next iteration.

return false; // this is equivalent of 'break' for jQuery loop

return;       // this is equivalent of 'continue' for jQuery loop

Note that $(selector).each() and $.each() are different functions.

References:

• $(selector).each()
• $.each()
• What is the difference between $.each(selector) and $(selector).each()

This is old question but I don't think the accepted answer is safe. It's good for creating a super user but not good if you want to grant privileges on a single database.

grant all privileges on mydb.* to myuser@'%' identified by 'mypasswd';
grant all privileges on mydb.* to myuser@localhost identified by 'mypasswd';

% seems to not cover socket communications, that the localhost is for. WITH GRANT OPTION is only good for the super user, otherwise it is usually a security risk.

Update for MySQL 5.7+ seems like this warns about:

Using GRANT statement to modify existing user's properties other than privileges is deprecated and will be removed in future release. Use ALTER USER statement for this operation.

So setting password should be with separate commands. Thanks to comment from @scary-wombat.

ALTER USER 'myuser'@'%' IDENTIFIED BY 'mypassword';
ALTER USER 'myuser'@'localhost' IDENTIFIED BY 'mypassword';

Hope this helps.

jQuery has an AjaxSetup() function that allows you to register global ajax handlers such as beforeSend and complete for all ajax calls as well as allow you to access the xhr object to do the progress that you are looking for

Here's my general-purpose function which parametrizes the CSS selector and rules, and optionally takes in a css filename (case-sensitive) if you wish to add to a particular sheet instead (otherwise, if you don't provide a CSS filename, it will create a new style element and append it to the existing head. It will make at most one new style element and re-use it on future function calls). Works with FF, Chrome, and IE9+ (maybe earlier too, untested).

function addCssRules(selector, rules, /*Optional*/ sheetName) {
    // We want the last sheet so that rules are not overridden.
    var styleSheet = document.styleSheets[document.styleSheets.length - 1];
    if (sheetName) {
        for (var i in document.styleSheets) {
            if (document.styleSheets[i].href && document.styleSheets[i].href.indexOf(sheetName) > -1) {
                styleSheet = document.styleSheets[i];
                break;
            }
        }
    }
    if (typeof styleSheet === 'undefined' || styleSheet === null) {
        var styleElement = document.createElement("style");
        styleElement.type = "text/css";
        document.head.appendChild(styleElement);
        styleSheet = styleElement.sheet;
    }

    if (styleSheet) {
        if (styleSheet.insertRule)
            styleSheet.insertRule(selector + ' {' + rules + '}', styleSheet.cssRules.length);
        else if (styleSheet.addRule)
            styleSheet.addRule(selector, rules);
    }
}

Use a shared container to transfer data between threads.

The HttpClient methods allow you to set the params in it's options.

You can configure it by importing the HttpClientModule from the @angular/common/http package.

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

@NgModule({
  imports: [ BrowserModule, HttpClientModule ],
  declarations: [ App ],
  bootstrap: [ App ]
})
export class AppModule {}

After that you can inject the HttpClient and use it to do the request.

import {HttpClient} from '@angular/common/http'

@Component({
  selector: 'my-app',
  template: `
    <div>
      <h2>Hello {{name}}</h2>
    </div>
  `,
})
export class App {
  name:string;
  constructor(private httpClient: HttpClient) {
    this.httpClient.get('/url', {
      params: {
        appid: 'id1234',
        cnt: '5'
      },
      observe: 'response'
    })
    .toPromise()
    .then(response => {
      console.log(response);
    })
    .catch(console.log);
  }
}

For angular versions prior to version 4 you can do the same using the Http service.

The Http.get method takes an object that implements RequestOptionsArgs as a second parameter.

The search field of that object can be used to set a string or a URLSearchParams object.

An example:

 // Parameters obj-
 let params: URLSearchParams = new URLSearchParams();
 params.set('appid', StaticSettings.API_KEY);
 params.set('cnt', days.toString());

 //Http request-
 return this.http.get(StaticSettings.BASE_URL, {
   search: params
 }).subscribe(
   (response) => this.onGetForecastResult(response.json()), 
   (error) => this.onGetForecastError(error.json()), 
   () => this.onGetForecastComplete()
 );

The documentation for the Http class has more details. It can be found here and an working example here.

It depends what kind of UUID you want.

• The standard Java UUID class generates Version 4 (random) UUIDs. (UPDATE - Version 3 (name) UUIDs can also be generated.) It can also handle other variants, though it cannot generate them. (In this case, "handle" means construct UUID instances from long, byte[] or String representations, and provide some appropriate accessors.)

• The Java UUID Generator (JUG) implementation purports to support "all 3 'official' types of UUID as defined by RFC-4122" ... though the RFC actually defines 4 types and mentions a 5th type.

For more information on UUID types and variants, there is a good summary in Wikipedia, and the gory details are in RFC 4122 and the other specifications.

If you're using NumPy/SciPy already you may as well use:

scipy.ndimage.imread(file_name, mode='L')

What worked for me was:

I had a process called "mysqld" running even when MAMP had been quit. I force quit the process, restarted MAMP and it worked again.

Go ahead and add [STAThread] to the main entry of your application, this indicates the COM threading model is single-threaded apartment (STA)

example:

static class Program
{
    /// <summary>
    /// The main entry point for the application.
    /// </summary>
    [STAThread]
    static void Main()
    {
        Application.EnableVisualStyles();
        Application.SetCompatibleTextRenderingDefault(false);
        Application.Run(new WebBrowser());
    }
}

Got to

gradle-wrapper.properties

Change the version of the below mentioned distribution (gradle-5.6.4-bin.zip)

distributionUrl=https://services.gradle.org/distributions/gradle-5.6.4-bin.zip

You can use the sort command:

sort -k2 -n yourfile

-n, --numeric-sort compare according to string numerical value

For example:

$ cat ages.txt 
Bob 12
Jane 48
Mark 3
Tashi 54

$ sort -k2 -n ages.txt 
Mark 3
Bob 12
Jane 48
Tashi 54

This was happening on two different clients' servers separated by several years, using the same code that was deployed on hundreds of other servers for that time without issue.

For these clients, it happened mostly on PHP scripts that had streaming HTML - that is, "Connection: close" pages where output was sent to the browser as the output became available.

It turned out that the connection between the PHP process and the web server was dropping prematurely, before the script completed and way before any timeout.

The problem was opcache.fast_shutdown = 1 in the main php.ini file. This directive is disabled by default, but it seems some server administrators believe there is a performance boost to be had here. In all of my tests, I have never noted a positive difference using this setting. In my experience, it has caused some scripts to actually execute more slowly, and has an awful track record of sometimes entering shutdown while the script is still executing, or even at the end of execution while the web server is still reading from the buffer. There is an old bug report from 2013, unresolved as of Feb 2017, which may be related: https://github.com/zendtech/ZendOptimizerPlus/issues/146

I have seen the following errors appear due to this ERR_INCOMPLETE_CHUNKED_ENCODING ERR_SPDY_PROTOCOL_ERROR Sometimes there are correlative segfaults logged; sometimes not.

If you experience either one, check your phpinfo, and make sure opcache.fast_shutdown is disabled.

You can create the branch via a hash:

git branch branchname <sha1-of-commit>

Or by using a symbolic reference:

git branch branchname HEAD~3

To checkout the branch when creating it, use

git checkout -b branchname <sha1-of-commit or HEAD~3>

One way - split you image into N rotating it slightly every time. I'd say 5 is enough. then create something like this in drawable

<animation-list   android:id="@+id/handimation" android:oneshot="false" 
    xmlns:android="http://schemas.android.com/apk/res/android">
    <item android:drawable="@drawable/progress1" android:duration="150" />
    <item android:drawable="@drawable/progress2" android:duration="150" />
    <item android:drawable="@drawable/progress3" android:duration="150" />
 </animation-list> 

code start

progress.setVisibility(View.VISIBLE);
AnimationDrawable frameAnimation = (AnimationDrawable)progress.getDrawable();
frameAnimation.setCallback(progress);
frameAnimation.setVisible(true, true);

code stop

AnimationDrawable frameAnimation = (AnimationDrawable)progress.getDrawable();
frameAnimation.stop();
frameAnimation.setCallback(null);
frameAnimation = null;
progress.setVisibility(View.GONE);

For ASP.NET5, i.e. ASPNETCORE, you can do the following in configure:

app.UseRequestLocalization(new RequestLocalizationOptions
{
    DefaultRequestCulture = new RequestCulture(new CultureInfo("en-gb")),
    SupportedCultures = new List<CultureInfo>
    {
        new CultureInfo("en-gb")
    },
            SupportedUICultures = new List<CultureInfo>
    {
        new CultureInfo("en-gb")
    }
});

Here's a series of blog posts that gives more information.

The standard solution:

 expr $d1 - $d2

You can also do:

echo $(( d1 - d2 ))

but beware that this will treat 07 as an octal number! (so 07 is the same as 7, but 010 is different than 10).

There are so many answers here suggesting to escape the dot with \. but I have been running into this issue over and over again: \. gives me the same result as .

However, these two expressions work for me:

$ grep -r 0\\.49 *

And:

$ grep -r 0[.]49 *

I'm using a "normal" bash shell on Ubuntu and Archlinux.

Edit, or, according to comments:

$ grep -r '0\.49' *

Note, the single-quotes doing the difference here.

Even though this is much later than the request, it might help others. Docmosis provides a Java API for creating documents in doc,pdf,odt format using documents as templates. It uses OpenOffice as the engine to perform the format conversions. Document manipulation and population is performed by Docmosis itself.

Brian, also worth throwing in here - the others are of course correct that you don't need to declare a string variable. However, next time you want to declare a string you don't need to do the following:

NSString *myString = [[NSString alloc] initWithFormat:@"SomeText"];

Although the above does work, it provides a retained NSString variable which you will then need to explicitly release after you've finished using it.

Next time you want a string variable you can use the "@" symbol in a much more convenient way:

NSString *myString = @"SomeText";

This will be autoreleased when you've finished with it so you'll avoid memory leaks too...

Hope that helps!

Developing on Windows, I ran into this problem when using git tfs. I solved it this way:

git config --global core.whitespace cr-at-eol

This basically tells Git that an end-of-line CR is not an error. As a result, those annoying ^M characters no longer appear at the end of lines in git diff, git show, etc.

It appears to leave other settings as-is; for instance, extra spaces at the end of a line still show as errors (highlighted in red) in the diff.

(Other answers have alluded to this, but the above is exactly how to set the setting. To set the setting for only one project, omit the --global.)

EDIT:

After many line-ending travails, I've had the best luck, when working on a .NET team, with these settings:

• NO core.eol setting
• NO core.whitespace setting
• NO core.autocrlf setting
• When running the Git installer for Windows, you'll get these three options:
  • Checkout Windows-style, commit Unix-style line endings <-- choose this one
  • Checkout as-is, commit Unix-style line endings
  • Checkout as-is, commit as-is

If you need to use the whitespace setting, you should probably enable it only on a per-project basis if you need to interact with TFS. Just omit the --global:

git config core.whitespace cr-at-eol

If you need to remove some core.* settings, the easiest way is to run this command:

git config --global -e

This opens your global .gitconfig file in a text editor, and you can easily delete the lines you want to remove. (Or you can put '#' in front of them to comment them out.)

I created my icons using this tool:

https://romannurik.github.io/AndroidAssetStudio/index.html

After I downloaded these (they were already pre named to ic_launcher, very useful!) I found the

mipmap ic_launcher folder under the res folder

and I replaced the pre icons with the ones I created. Reinstall your app, and you'll see your new icon!

When the normType is NORM_MINMAX, cv::normalize normalizes _src in such a way that the min value of dst is alpha and max value of dst is beta. cv::normalize does its magic using only scales and shifts (i.e. adding constants and multiplying by constants).

CV_8UC1 says how many channels dst has.

The documentation here is pretty clear: http://docs.opencv.org/modules/core/doc/operations_on_arrays.html#normalize

res = ActiveRecord::Base.connection_pool.with_connection { |con| con.exec_query( "SELECT 1;" ) }

The above code is an example for

1. executing arbitrary SQL on your database-connection
2. returning the connection back to the connection pool afterwards

Posting my full function based on Kindall's solution. I was able to support any alphanumeric characters mixed in with the numbers by padding each version section with leading zeros.

While certainly not as pretty as his one-liner function, it seems to work well with alpha-numeric version numbers. (Just be sure to set the zfill(#) value appropriately if you have long strings in your versioning system.)

def versiontuple(v):
   filled = []
   for point in v.split("."):
      filled.append(point.zfill(8))
   return tuple(filled)

.

>>> versiontuple("10a.4.5.23-alpha") > versiontuple("2a.4.5.23-alpha")
True


>>> "10a.4.5.23-alpha" > "2a.4.5.23-alpha"
False

JSONArray successObject=new JSONArray();
JSONObject dataObject=new JSONObject();
successObject.put(dataObject.toString());

This works for me.

You can also try this:

for %%a in (*) do echo %%a

Using a for loop, you can echo out all the file names of the current directory.

To print them directly from the console:

for %a in (*) do @echo %a

if you want to use it in all of your classes you can use:

public var yourVariable = "something"

if you want to use just in one class you can use :

var yourVariable = "something"

For me i followed the above answer and modified it a bit:

1. Just grab your ipv4 address using ipconfig on command prompt
2. Go to the file in which flask code is present
3. In main function write app.run(host= 'your ipv4 address')

Eg:

Make sure that there is no another form with the same name and make sure that there is no name="submit" or id="submit" in the form.

You have to override CLLocationManager.didUpdateLocations (part of CLLocationManagerDelegate) to get notified when the location manager retrieves the current location:

func locationManager(_ manager: CLLocationManager, didUpdateLocations locations: [CLLocation]) {
    if let location = locations.last{
        let center = CLLocationCoordinate2D(latitude: location.coordinate.latitude, longitude: location.coordinate.longitude)
        let region = MKCoordinateRegion(center: center, span: MKCoordinateSpan(latitudeDelta: 0.01, longitudeDelta: 0.01))
        self.map.setRegion(region, animated: true)

NOTE: If your target is iOS 8 or above, you must include the NSLocationAlwaysUsageDescription or NSLocationWhenInUseUsageDescription key in your Info.plist to get the location services to work.

The conversion fails (java.lang.ClassCastException: java.lang.String cannot be cast to java.util.ArrayList) because you have surely some objects that are not ArrayList. verify the types of your different objects.

Another possibility:

1. Create a UIButton in Interface builder.
2. Give it a type 'Custom'
3. Now, in IB it is possible to change the background color

However, the button is square, and that is not what we want. Create an IBOutlet with a reference to this button and add the following to the viewDidLoad method:

[buttonOutlet.layer setCornerRadius:7.0f];
[buttonOutlet.layer setClipToBounds:YES];

Don't forget to import QuartzCore.h

You can even try this.

   String date="09/08/1980";    // take a string  date
    Timestamp ts=null;  //declare timestamp
    Date d=new Date(date); // Intialize date with the string date
    if(d!=null){  // simple null check
        ts=new java.sql.Timestamp(d.getTime()); // convert gettime from date and assign it to your timestamp.
    }

You could use an fstream and open it with the std::ios::app flag. Have a look at the code below and it should clear your head.

...
fstream f("filename.ext", f.out | f.app);
f << "any";
f << "text";
f << "written";
f << "wll";
f << "be append";
...

You can find more information about the open modes here and about fstreams here.

This is also a singleton:

function Singleton() {
    var i = 0;
    var self = this;

    this.doStuff = function () {
        i = i + 1;
        console.log('do stuff', i);
    };

    Singleton = function () { return self };
    return this;
}

s = Singleton();
s.doStuff();

Try figsize param in df.plot(figsize=(width,height)):

df = pd.DataFrame({"a":[1,2],"b":[1,2]})
df.plot(figsize=(3,3));

df = pd.DataFrame({"a":[1,2],"b":[1,2]})
df.plot(figsize=(5,3));

The size in figsize=(5,3) is given in inches per (width, height)

Use:

android:backgroundTint="@color/customColor"

Or even :

android:background="@color/customColor"

and that will give custom color to the button.

The Ruby Style Guide says it better than I could:

Use &&/|| for boolean expressions, and/or for control flow. (Rule of thumb: If you have to use outer parentheses, you are using the wrong operators.)

# boolean expression
if some_condition && some_other_condition
  do_something
end

# control flow
document.saved? or document.save!

I think something like this:

btn.BackgroundImage = Properties.Resources.*Image_Identifier*;

Where *Image_Identifier* is an identifier of the image in your resources.

I know this is a really old question.. and it appears it was answered.. But I got here with the same question but a different reason for the question, and so a slightly different answer worked for me. I have a nice reusable generic datagridview that takes the datasource supplied to it and just displays the columns in their default order. I put aliases and column order and selection at the dataset's tableadapter level in designer. However changing the select query order of columns doesn't seem to impact the columns returned through the dataset. I have found the only way to do this in the designer, is to remove all the columns selected within the tableadapter, adding them back in the order you want them selected.

Remove the comma?

select /*+USE_HASH( a b ) */ to_char(date, 'MM/DD/YYYY HH24:MI:SS') as LABEL,
ltrim(rtrim(substr(oled, 9, 16))) as VALUE
from rrfh a, rrf b
where ltrim(rtrim(substr(oled, 1, 9))) = 'stata kish' 
and a.xyz = b.xyz

Have a look at FROM

SELECTING from multiple tables You can include multiple tables in the FROM clause by listing the tables with a comma in between each table name

When you are using a virtualenv, you can specify a requirements.txt file to install all the dependencies.

A typical usage:

$ pip install -r requirements.txt

The packages need to be in a specific format for pip to understand, which is

feedparser==5.1.3
wsgiref==0.1.2
django==1.4.2
...

That is the "requirements format".

Here, django==1.4.2 implies install django version 1.4.2 (even though the latest is 1.6.x). If you do not specify ==1.4.2, the latest version available would be installed.

You can read more in "Virtualenv and pip Basics", and the official "Requirements File Format" documentation.

Couldn't find any official documentation (no surprise there) but according to this interesting article, those elements are injected in order to enable Word to convert the HTML back to fully compatible Word document, with everything preserved.

The relevant paragraph:

Microsoft added the special tags to Word's HTML with an eye toward backward compatibility. Microsoft wanted you to be able to save files in HTML complete with all of the tracking, comments, formatting, and other special Word features found in traditional DOC files. If you save a file in HTML and then reload it in Word, theoretically you don't loose anything at all.

This makes lots of sense.

For your specific question.. the o in the <o:p> means "Office namespace" so anything following the o: in a tag means "I'm part of Office namespace" - in case of <o:p> it just means paragraph, the equivalent of the ordinary <p> tag.

I assume that every HTML tag has its Office "equivalent" and they have more.

create two files e.g app.js and tools.js

app.js

const tools= require("./tools.js")


var x = tools.add(4,2) ;

var y = tools.subtract(4,2);


console.log(x);
console.log(y);

tools.js

 const add = function(x, y){
        return x+y;
    }
 const subtract = function(x, y){
            return x-y;
    }

    module.exports ={
        add,subtract
    }

output

Without reading you can't do this. But you can use a work around like below.

You can use mark() and reset() methods to do this.

mark(int readlimit) method marks the current position in this input stream.

reset() method repositions this stream to the position at the time the mark method was last called on this input stream.

Before you can use the mark and reset, you need to test out whether these operations are supported on the inputstream you’re reading off. You can do that with markSupported.

The mark method accepts an limit (integer), which denotes the maximum number of bytes that are to be read ahead. If you read more than this limit, you cannot return to this mark.

To apply this functionalities for this use case, we need to mark the position as 0 and then read the input stream. There after we need to reset the input stream and the input stream will be reverted to the original one.

    if (inputStream.markSupported()) {
          inputStream.mark(0);
          if (inputStream.read() != -1) {
               inputStream.reset();
          } else {
               //Inputstream is empty
          }
    }

Here if the input stream is empty then read() method will return -1.

The variable item is a string. An index looks like this:

>>> mystring = 'helloworld'
>>> print mystring[0]
'h'

The above example uses the 0 index of the string to refer to the first character.

Strings can't have string indices (like dictionaries can). So this won't work:

>>> mystring = 'helloworld'
>>> print mystring['stringindex']
TypeError: string indices must be integers

MYSQL Query Auto Increment Solution. It works perfect when you have inserted many records during testing phase of software. Now you want to launch your application live to your client and You want to start auto increment from 1.

To avoid any unwanted problems, for safer side First export .sql file.
Then follow the below steps:

• Step 1) First Create the copy of an existing table MySQL Command to create Copy:

  CREATE TABLE new_Table_Name  SELECT * FROM existing_Table_Name;
  

  The exact copy of a table is created with all rows except Constraints.
  It doesn’t copy constraints like Auto Increment and Primary Key into new_Table_name

• Step 2) Delete All rows If Data is not inserted in testing phase and it is not useful. If Data is important then directly go to Step 3.

  DELETE from new_Table_Name;
  

• Step 3) To Add Constraints, Goto Structure of a table

  • 3A) Add primary key constraint from More option (If You Require).
  • 3B) Add Auto Increment constraint from Change option. For this set Defined value as None.
  • 3C) Delete existing_Table_Name and
  • 3D) rename new_Table_Name to existing_Table_Name.

Now It will work perfectly. The new first record will take first value in Auto Increment column.

There is a useful difference between call and start /wait when calling regsvr32.exe /s for example, also referenced by Gary in in his answer to how-do-i-get-the-application-exit-code-from-a-windows-command-line

call regsvr32.exe /s broken.dll
echo %errorlevel%

will always return 0 but

start /wait regsvr32.exe /s broken.dll
echo %errorlevel%

will return the error level from regsvr32.exe

Towards the second half of Create REST API using ASP.NET MVC that speaks both JSON and plain XML, to quote:

Now we need to accept JSON and XML payload, delivered via HTTP POST. Sometimes your client might want to upload a collection of objects in one shot for batch processing. So, they can upload objects using either JSON or XML format. There's no native support in ASP.NET MVC to automatically parse posted JSON or XML and automatically map to Action parameters. So, I wrote a filter that does it."

He then implements an action filter that maps the JSON to C# objects with code shown.

It seems that your configuration is using the print option for numpy.seterr:

>>> import numpy as np
>>> np.array([1])/0   #'warn' mode
__main__:1: RuntimeWarning: divide by zero encountered in divide
array([0])
>>> np.seterr(all='print')
{'over': 'warn', 'divide': 'warn', 'invalid': 'warn', 'under': 'ignore'}
>>> np.array([1])/0   #'print' mode
Warning: divide by zero encountered in divide
array([0])

This means that the warning you see is not a real warning, but it's just some characters printed to stdout(see the documentation for seterr). If you want to catch it you can:

1. Use numpy.seterr(all='raise') which will directly raise the exception. This however changes the behaviour of all the operations, so it's a pretty big change in behaviour.
2. Use numpy.seterr(all='warn'), which will transform the printed warning in a real warning and you'll be able to use the above solution to localize this change in behaviour.

Once you actually have a warning, you can use the warnings module to control how the warnings should be treated:

>>> import warnings
>>> 
>>> warnings.filterwarnings('error')
>>> 
>>> try:
...     warnings.warn(Warning())
... except Warning:
...     print 'Warning was raised as an exception!'
... 
Warning was raised as an exception!

Read carefully the documentation for filterwarnings since it allows you to filter only the warning you want and has other options. I'd also consider looking at catch_warnings which is a context manager which automatically resets the original filterwarnings function:

>>> import warnings
>>> with warnings.catch_warnings():
...     warnings.filterwarnings('error')
...     try:
...         warnings.warn(Warning())
...     except Warning: print 'Raised!'
... 
Raised!
>>> try:
...     warnings.warn(Warning())
... except Warning: print 'Not raised!'
... 
__main__:2: Warning: 

dict.update() looks like it will do what you want...

>> orig.update(extra)
>>> orig
{'A': 1, 'C': 3, 'B': 2, 'E': 5, 'D': 4}
>>> 

Perhaps, though, you don't want to update your original dictionary, but work on a copy:

>>> dest = orig.copy()
>>> dest.update(extra)
>>> orig
{'A': 1, 'C': 3, 'B': 2}
>>> dest
{'A': 1, 'C': 3, 'B': 2, 'E': 5, 'D': 4}

Set the GroupName property of both radio buttons to the same value. You could also try using a RadioButtonGroup, which does this for you automatically.

If your goal is to make the exception and stacktrace message look exactly like when python throws an error, the following works in both python 2+3:

import sys, traceback


def format_stacktrace():
    parts = ["Traceback (most recent call last):\n"]
    parts.extend(traceback.format_stack(limit=25)[:-2])
    parts.extend(traceback.format_exception(*sys.exc_info())[1:])
    return "".join(parts)

# EXAMPLE BELOW...

def a():
    b()


def b():
    c()


def c():
    d()


def d():
    assert False, "Noooh don't do it."


print("THIS IS THE FORMATTED STRING")
print("============================\n")

try:
    a()
except:
    stacktrace = format_stacktrace()
    print(stacktrace)

print("THIS IS HOW PYTHON DOES IT")
print("==========================\n")
a()

It works by removing the last format_stacktrace() call from the stack and joining the rest. When run, the example above gives the following output:

THIS IS THE FORMATTED STRING
============================

  File "test.py", line 31, in <module>

When you start Android studio Look for Profile or Debug apk.

After clicking you get the option to browse for the saved apk and you will be bale to later run it using emulator
