I have found the solution. While the Visual Studio IDE installed successfully it did not install any build tools and therefore did not install the C++ compiler.

By attempting to manually create a C++ project in the Visual Studio 2015 GUI I was able to prompt it to download the C++ packages. CMake was then able to find the compiler without any difficulty.

If the size of strings is relatively big (hundreds of bytes or more) and c++17 is available, you might want to use Boyer-Moore-Horspool searcher (example from cppreference.com):

#include <iostream>
#include <string>
#include <algorithm>
#include <functional>

int main()
{
    std::string in = "Lorem ipsum dolor sit amet, consectetur adipiscing elit,"
                     " sed do eiusmod tempor incididunt ut labore et dolore magna aliqua";
    std::string needle = "pisci";
    auto it = std::search(in.begin(), in.end(),
                   std::boyer_moore_searcher(
                       needle.begin(), needle.end()));
    if(it != in.end())
        std::cout << "The string " << needle << " found at offset "
                  << it - in.begin() << '\n';
    else
        std::cout << "The string " << needle << " not found\n";
}

An arbitrary OAuth access token can't be used for authentication, because the meaning of the token is outside of the OAuth Core spec. It could be intended for a single use or narrow expiration window, or it could provide access which the user doesn't want to give. It's also opaque, and the OAuth consumer which obtained it might never have seen any type of user identifier.

An OAuth service provider and one or more consumers could easily use OAuth to provide a verifiable authentication token, and there are proposals and ideas to do this out there, but an arbitrary service provider speaking only OAuth Core can't provide this without other co-ordination with a consumer. The Google-specific AuthSubTokenInfo REST method, along with the user's identifier, is close, but it isn't suitable, either, since it could invalidate the token, or the token could be expired.

If your Google ID is an OpenId identifier, and your 'public interface' is either a web app or can call up the user's browser, then you should probably use Google's OpenID OP.

OpenID consists of just sending the user to the OP and getting a signed assertion back. The interaction is solely for the benefit of the RP. There is no long-lived token or other user-specific handle which could be used to indicate that a RP has successfully authenticated a user with an OP.

One way to verify a previous authentication against an OpenID identifier is to just perform authentication again, assuming the same user-agent is being used. The OP should be able to return a positive assertion without user interaction (by verifying a cookie or client cert, for example). The OP is free to require another user interaction, and probably will if the authentication request is coming from another domain (my OP gives me the option to re-authenticate this particular RP without interacting in the future). And in Google's case, the UI that the user went through to get the OAuth token might not use the same session identifier, so the user will have to re-authenticate. But in any case, you'll be able to assert the identity.

Try this-

$('select').on('change', function() {_x000D_
  alert( this.value );_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<select>_x000D_
    <option value="1">One</option>_x000D_
    <option value="2">Two</option>_x000D_
</select>

You can also reference with onchange event-

function getval(sel)_x000D_
{_x000D_
    alert(sel.value);_x000D_
}

<select onchange="getval(this);">_x000D_
    <option value="1">One</option>_x000D_
    <option value="2">Two</option>_x000D_
</select>

Using JSONSerialization always felt unSwifty and unwieldy, but it is even more so with the arrival of Codable in Swift 4. If you wield a [String:Any] in front of a simple struct it will ... hurt. Check out this in a Playground:

import Cocoa

let data = "[{\"form_id\":3465,\"canonical_name\":\"df_SAWERQ\",\"form_name\":\"Activity 4 with Images\",\"form_desc\":null}]".data(using: .utf8)!

struct Form: Codable {
    let id: Int
    let name: String
    let description: String?

    private enum CodingKeys: String, CodingKey {
        case id = "form_id"
        case name = "form_name"
        case description = "form_desc"
    }
}

do {
    let f = try JSONDecoder().decode([Form].self, from: data)
    print(f)
    print(f[0])
} catch {
    print(error)
}

With minimal effort handling this will feel a whole lot more comfortable. And you are given a lot more information if your JSON does not parse properly.

Utility or helper classes/methods that you would like to access from many other classes within the same assembly, but that you want to ensure code in other assemblies can't access.

From MSDN (via archive.org):

A common use of internal access is in component-based development because it enables a group of components to cooperate in a private manner without being exposed to the rest of the application code. For example, a framework for building graphical user interfaces could provide Control and Form classes that cooperate using members with internal access. Since these members are internal, they are not exposed to code that is using the framework.

You can also use the internal modifier along with the InternalsVisibleTo assembly level attribute to create "friend" assemblies that are granted special access to the target assembly internal classes.

This can be useful for creation of unit testing assemblies that are then allowed to call internal members of the assembly to be tested. Of course no other assemblies are granted this level of access, so when you release your system, encapsulation is maintained.

I bought a MacBook Pro yesterday (Mac OS X v10.8 (Mountain Lion)) and there is no JDK installed by default...

As well as javac, I also found it didn't have packages such as SVN installed. It turns out you can get everything from the Apple developer page (you will need to register with your AppleID). SVN is part of the "Command Line Tools" package.

This is what happens on a fresh MacBook:

Hopefully this will help out other newbies like me ;)

Not as nice as a single ?, but it works:

var thing = foo && foo.bar || null;

You can use as many && as you like:

var thing = foo && foo.bar && foo.bar.check && foo.bar.check.x || null;

I figured out that this behaves like a mousedown event:

button:active:hover {}

Tested Code:

$("input").css("background","red");

Complete:

$('input:text').focus(function () {
    $(this).css({ 'background': 'Black' });
});

$('input:text').blur(function () {
    $(this).css({ 'background': 'red' });
});

Tested in version:

jquery-1.9.1.js
jquery-ui-1.10.3.js

Use __LINE__, but what is its type?

LINE The presumed line number (within the current source file) of the current source line (an integer constant).

As an integer constant, code can often assume the value is __LINE__ <= INT_MAX and so the type is int.

To print in C, printf() needs the matching specifier: "%d". This is a far lesser concern in C++ with cout.

Pedantic concern: If the line number exceeds INT_MAX¹ (somewhat conceivable with 16-bit int), hopefully the compiler will produce a warning. Example:

format '%d' expects argument of type 'int', but argument 2 has type 'long int' [-Wformat=]

Alternatively, code could force wider types to forestall such warnings.

printf("Not logical value at line number %ld\n", (long) __LINE__);
//or
#include <stdint.h>
printf("Not logical value at line number %jd\n", INTMAX_C(__LINE__));

Avoid printf()

To avoid all integer limitations: stringify. Code could directly print without a printf() call: a nice thing to avoid in error handling² .

#define xstr(a) str(a)
#define str(a) #a

fprintf(stderr, "Not logical value at line number %s\n", xstr(__LINE__));
fputs("Not logical value at line number " xstr(__LINE__) "\n", stderr);

¹ Certainly poor programming practice to have such a large file, yet perhaps machine generated code may go high.

² In debugging, sometimes code simply is not working as hoped. Calling complex functions like *printf() can itself incur issues vs. a simple fputs().

var d = new Date(2011,10,30);

as months are indexed from 0 in js.

Add semi-colons ; to the end of the function calls in order for them both to work.

 <input id="btn" type="button" value="click" onclick="pay(); cls();"/>

I don't believe the last one is required but hey, might as well add it in for good measure.

Here is a good reference from SitePoint http://reference.sitepoint.com/html/event-attributes/onclick

All the answers so far are incorrect. The Registry normally uses port 1099, but you can change it. But that's not the end of the story. Remote objects also use ports, and not necessarily 1099.

If you don't specify a port when exporting, RMI uses a random port. The solution is therefore to specify a port number when exporting. And this is a port that needs opening in the firewall, if any.

• In the case where your remote object extends UnicastRemoteObject, have its constructor call super(port) with some non-zero port number.

• In the case where it doesn't extend UnicastRemoteObject, provide a non-zero port number to UnicastRemoteObject.exportObject().

There are several wrinkles to this.

• If you aren't using socket factories, and you provide a non-zero port number when exporting your first remote object, RMI will automatically share that port with subsequently exported remote objects without specified port numbers, or specifying zero. That first remote object includes a Registry created with LocateRegistry.createRegistry(). So if you create a Registry on port 1099, all other objects exported from that JVM can share port 1099.

• If you are using socket factories, your RMIServerSocketFactory must have a sensible implementation of equals() for port sharing to work, i.e. one that doesn't just rely on object identity via == or Object.equals().

• If either you don't provide a server socket factory, or you do provide one with a sensible equals() method, but not both, you can use the same non-zero explicit port number for all remote objects, e.g. createRegistry(1099) followed by any number of super(1099) or exportObject(..., 1099) calls.

How can I declare a class type, so that I ensure the object is a constructor of a general class?

A Constructor type could be defined as:

 type AConstructorTypeOf<T> = new (...args:any[]) => T;

 class A { ... }

 function factory(Ctor: AConstructorTypeOf<A>){
   return new Ctor();
 }

const aInstance = factory(A);

Instead of creating too many short Polylines just create one like here:

PolylineOptions options = new PolylineOptions().width(5).color(Color.BLUE).geodesic(true);
for (int z = 0; z < list.size(); z++) {
    LatLng point = list.get(z);
    options.add(point);
}
line = myMap.addPolyline(options);

I'm also not sure you should use geodesic when your points are so close to each other.

git diff branch_1..branch_2

That will produce the diff between the tips of the two branches. If you'd prefer to find the diff from their common ancestor to test, you can use three dots instead of two:

git diff branch_1...branch_2

In case somebody has this problem

Cannot invoke initializer for type 'Int' with an argument list of type '(Array<Element>.Index?)'

jsut do this

extension Int {
    var toInt: Int {
        return self
    }
}

then

guard let finalIndex = index?.toInt else {
    return false
}

The right way to do it:

In .NET Core you can inject the IConfiguration as a parameter into your Class constructor, and it will be available.

public class MyClass 
{
    private IConfiguration configuration;
    public MyClass(IConfiguration configuration)
    {
        ConnectionString = new configuration.GetValue<string>("ConnectionString");
    }

Now, when you want to create an instance of your class, since your class gets injected the IConfiguration, you won't be able to just do new MyClass(), because it needs a IConfiguration parameter injected into the constructor, so, you will need to inject your class as well to the injecting chain, which means two simple steps:

1) Add your Class/es - where you want to use the IConfiguration, to the IServiceCollection at the ConfigureServices() method in Startup.cs

services.AddTransient<MyClass>();

2) Define an instance - let's say in the Controller, and inject it using the constructor:

public class MyController : ControllerBase
{
    private MyClass _myClass;
    public MyController(MyClass myClass)
    {
        _myClass = myClass;
    }

Now you should be able to enjoy your _myClass.configuration freely...

Another option:

If you are still looking for a way to have it available without having to inject the classes into the controller, then you can store it in a static class, which you will configure in the Startup.cs, something like:

public static class MyAppData
{
    public static IConfiguration Configuration;
}

And your Startup constructor should look like this:

public Startup(IConfiguration configuration)
{
    Configuration = configuration;
    MyAppData.Configuration = configuration;
}

Then use MyAppData.Configuration anywhere in your program.

Don't confront me why the first option is the right way, I can just see experienced developers always avoid garbage data along their way, and it's well understood that it's not the best practice to have loads of data available in memory all the time, neither is it good for performance and nor for development, and perhaps it's also more secure to only have with you what you need.

An easy way I'm using:

file_put_contents($output_file, file_get_contents($base64_string));

This works well because file_get_contents can read data from a URI, including a data:// URI.

As others have said, you can use a DateTime and ignore the date, or use a TimeSpan. Personally I'm not keen on either of these solutions, as neither type really reflects the concept you're trying to represent - I regard the date/time types in .NET as somewhat on the sparse side which is one of the reasons I started Noda Time. In Noda Time, you can use the LocalTime type to represent a time of day.

One thing to consider: the time of day is not necessarily the length of time since midnight on the same day...

(As another aside, if you're also wanting to represent a closing time of a shop, you may find that you want to represent 24:00, i.e. the time at the end of the day. Most date/time APIs - including Noda Time - don't allow that to be represented as a time-of-day value.)

That means sql group by 1st column in your select clause, we always use this GROUP BY 1 together with ORDER BY 1, besides you can also use like this GROUP BY 1,2,3.., of course it is convenient for us but you need to pay attention to that condition the result may be not what you want if some one has modified your select columns, and it's not visualized

This is a DevExpress specific answer based on the top-voted answer by Gregor S. (currently it has 128 votes).

This means we can keep the styling consistent across the entire application:

Unfortunately, the original answer doesn't work with a ComboBoxEdit from DevExpress without some modifications.

First, the XAML for the ComboBoxEdit:

<dxe:ComboBoxEdit ItemsSource="{Binding Source={xamlExtensions:XamlExtensionEnumDropdown {x:myEnum:EnumFilter}}}"
    SelectedItem="{Binding BrokerOrderBookingFilterSelected, Mode=TwoWay, UpdateSourceTrigger=PropertyChanged}"
    DisplayMember="Description"
    MinWidth="144" Margin="5" 
    HorizontalAlignment="Left"
    IsTextEditable="False"
    ValidateOnTextInput="False"
    AutoComplete="False"
    IncrementalFiltering="True"
    FilterCondition="Like"
    ImmediatePopup="True"/>

Needsless to say, you will need to point xamlExtensions at the namespace that contains the XAML extension class (which is defined below):

xmlns:xamlExtensions="clr-namespace:XamlExtensions"

And we have to point myEnum at the namespace that contains the enum:

xmlns:myEnum="clr-namespace:MyNamespace"

Then, the enum:

namespace MyNamespace
{
    public enum EnumFilter
    {
        [Description("Free as a bird")]
        Free = 0,

        [Description("I'm Somewhat Busy")]
        SomewhatBusy = 1,

        [Description("I'm Really Busy")]
        ReallyBusy = 2
    }
}

The problem in with the XAML is that we can't use SelectedItemValue, as this throws an error as the setter is unaccessable (bit of an oversight on your part, DevExpress). So we have to modify our ViewModel to obtain the value directly from the object:

private EnumFilter _filterSelected = EnumFilter.All;
public object FilterSelected
{
    get
    {
        return (EnumFilter)_filterSelected;
    }
    set
    {
        var x = (XamlExtensionEnumDropdown.EnumerationMember)value;
        if (x != null)
        {
            _filterSelected = (EnumFilter)x.Value;
        }
        OnPropertyChanged("FilterSelected");
    }
}

For completeness, here is the XAML extension from the original answer (slightly renamed):

namespace XamlExtensions
{
    /// <summary>
    ///     Intent: XAML markup extension to add support for enums into any dropdown box, see http://bit.ly/1g70oJy. We can name the items in the
    ///     dropdown box by using the [Description] attribute on the enum values.
    /// </summary>
    public class XamlExtensionEnumDropdown : MarkupExtension
    {
        private Type _enumType;


        public XamlExtensionEnumDropdown(Type enumType)
        {
            if (enumType == null)
            {
                throw new ArgumentNullException("enumType");
            }

            EnumType = enumType;
        }

        public Type EnumType
        {
            get { return _enumType; }
            private set
            {
                if (_enumType == value)
                {
                    return;
                }

                var enumType = Nullable.GetUnderlyingType(value) ?? value;

                if (enumType.IsEnum == false)
                {
                    throw new ArgumentException("Type must be an Enum.");
                }

                _enumType = value;
            }
        }

        public override object ProvideValue(IServiceProvider serviceProvider)
        {
            var enumValues = Enum.GetValues(EnumType);

            return (
                from object enumValue in enumValues
                select new EnumerationMember
                       {
                           Value = enumValue,
                           Description = GetDescription(enumValue)
                       }).ToArray();
        }

        private string GetDescription(object enumValue)
        {
            var descriptionAttribute = EnumType
                .GetField(enumValue.ToString())
                .GetCustomAttributes(typeof (DescriptionAttribute), false)
                .FirstOrDefault() as DescriptionAttribute;


            return descriptionAttribute != null
                ? descriptionAttribute.Description
                : enumValue.ToString();
        }

        #region Nested type: EnumerationMember
        public class EnumerationMember
        {
            public string Description { get; set; }
            public object Value { get; set; }
        }
        #endregion
    }
}

You shouldn't call viewDidLoad method manually, Instead if you want to reload any data or any UI, you can use this:

override func viewDidLoad() {
    super.viewDidLoad();

    let myButton = UIButton()

    // When user touch myButton, we're going to call loadData method
    myButton.addTarget(self, action: #selector(self.loadData), forControlEvents: .TouchUpInside)

    // Load the data
    self.loadData();
}

func loadData() {
    // code to load data from network, and refresh the interface
    tableView.reloadData()
}

Whenever you want to reload the data and refresh the interface, you can call self.loadData()

Was looking at how to trust a certificate while using jenkins cli, and found https://issues.jenkins-ci.org/browse/JENKINS-12629 which has some recipe for that.

This will give you the certificate:

openssl s_client -connect ${HOST}:${PORT} </dev/null

if you are interested only in the certificate part, cut it out by piping it to:

| sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p'

and redirect to a file:

> ${HOST}.cert

Then import it using keytool:

keytool -import -noprompt -trustcacerts -alias ${HOST} -file ${HOST}.cert \
    -keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS}

In one go:

HOST=myhost.example.com
PORT=443
KEYSTOREFILE=dest_keystore
KEYSTOREPASS=changeme

# get the SSL certificate
openssl s_client -connect ${HOST}:${PORT} </dev/null \
    | sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > ${HOST}.cert

# create a keystore and import certificate
keytool -import -noprompt -trustcacerts \
    -alias ${HOST} -file ${HOST}.cert \
    -keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS}

# verify we've got it.
keytool -list -v -keystore ${KEYSTOREFILE} -storepass ${KEYSTOREPASS} -alias ${HOST}

This would require me to reformat the data into lists inside lists, which seems to defeat the purpose of using pandas in the first place.

No it doesn't, just convert to a NumPy array:

>>> data = np.asarray(df)

This takes constant time because it just creates a view on your data. Then feed it to scikit-learn:

>>> from sklearn.linear_model import LinearRegression
>>> lr = LinearRegression()
>>> X, y = data[:, 1:], data[:, 0]
>>> lr.fit(X, y)
LinearRegression(copy_X=True, fit_intercept=True, normalize=False)
>>> lr.coef_
array([  4.01182386e-01,   3.51587361e-04])
>>> lr.intercept_
14.952479503953672

rowMeans is nice, but if you are still trying to wrap your head around the apply family of functions, this is a good opprotunity to begin understanding it.

DF['Mean'] <- apply(DF[,2:4], 1, mean)

Notice I'm doing a slightly different assignment than the first example. This approach makes it easier to incorporate it into for loops.

It needs to be done as following:

    getScrollView().post(new Runnable() {

        @Override
        public void run() {
            getScrollView().fullScroll(ScrollView.FOCUS_DOWN);
        }
    });

This way the view is first updated and then scrolls to the "new" bottom.

onLocationChange may also be useful. Not sure if this is a Mozilla-only thing though, appears that it might be.

You can use the following option to check for the files:

wget --delete-after URL

curl will encode the data for you, just drop your raw field data into the fields array and tell it to "go".

In our current project, we use

[ComVisible(false)]

It controls accessibility of an individual managed type or member, or of all types within an assembly, to COM.

This is the implementation coming from the Apache camel project:

/**
 * Checks to see if a specific port is available.
 *
 * @param port the port to check for availability
 */
public static boolean available(int port) {
    if (port < MIN_PORT_NUMBER || port > MAX_PORT_NUMBER) {
        throw new IllegalArgumentException("Invalid start port: " + port);
    }

    ServerSocket ss = null;
    DatagramSocket ds = null;
    try {
        ss = new ServerSocket(port);
        ss.setReuseAddress(true);
        ds = new DatagramSocket(port);
        ds.setReuseAddress(true);
        return true;
    } catch (IOException e) {
    } finally {
        if (ds != null) {
            ds.close();
        }

        if (ss != null) {
            try {
                ss.close();
            } catch (IOException e) {
                /* should not be thrown */
            }
        }
    }

    return false;
}

They are checking the DatagramSocket as well to check if the port is avaliable in UDP and TCP.

Hope this helps.

When running the command: cordova plugin remove <PLUGIN NAME>, ensure that you do not add the version number to the plugin name. Just plain plugin name, for example:

cordova plugin remove cordova.plugin_name 

and not:

cordova plugin remove cordova.plugin_name 0.01 

or

cordova plugin remove "cordova.plugin_name 0.01"

In case there is a privilege issue, run with sudo if you are on a *nix system, for example:

sudo cordova plugin remove cordova.plugin_name

Then you may add --save to remove it from the config.xml file. For example:

cordova plugin remove cordova.plugin_name --save

Try: localhost:8080/phpmyadmin/

Add reference to COM "Active DS Type Library"

            Int32 nameTypeNT4               = (int) ActiveDs.ADS_NAME_TYPE_ENUM.ADS_NAME_TYPE_NT4;

            Int32 nameTypeUserPrincipalName = (int) ActiveDs.ADS_NAME_TYPE_ENUM.ADS_NAME_TYPE_USER_PRINCIPAL_NAME;

            ActiveDs.NameTranslate nameTranslate = new ActiveDs.NameTranslate();

            // Convert NT name DOMAIN\User into AD distinguished name 
            // "CN= User\\, Name,OU=IT,OU=All Users,DC=Company,DC=com"
            nameTranslate.Set(nameTypeNT4, ntUser);

            String distinguishedName = nameTranslate.Get(nameTypeDN);

            Console.WriteLine(distinguishedName);

            // Convert AD distinguished name "CN= User\\, Name,OU=IT,OU=All Users,DC=Company,DC=com" 
            // into NT name DOMAIN\User
            ntUser = String.Empty;
            nameTranslate.Set(nameTypeDN, distinguishedName);
            ntUser = nameTranslate.Get(nameTypeNT4);
            Console.WriteLine(ntUser);

            // Convert NT name DOMAIN\User into AD UserPrincipalName [email protected]
            nameTranslate.Set(nameTypeNT4, ntUser);
            String userPrincipalName = nameTranslate.Get(nameTypeUserPrincipalName);

            Console.WriteLine(userPrincipalName);

mysz = mysz.replace(" ","");

First with space, second without space.

Then it is done.

Not OP's answer but as this was the first question that popped up for me in google, Id also like to add that users searching for this might need to reseed their table, which was the case for me

DBCC CHECKIDENT(tablename)

This works for me (Ubuntu 13.10 Desktop to an Ubuntu 14.04 Server) :-

 sudo umount -f /mnt/my_share

Mounted with

 sudo mount -t cifs -o username=me,password=mine //192.168.0.111/serv_share /mnt/my_share

where serv_share is that set up and pointed to in the smb.conf file.

$.ajax({
    type: 'POST',
    url: 'popup.aspx/GetJewellerAssets',      
    data: "jewellerId=" + filter+ "&locale=" +  locale,  
    success: AjaxSucceeded,
    error: AjaxFailed
});

The answer you want depends very much on how and why you want to break up the data frame.

For example, if you want to leave out some variables, you can create new data frames from specific columns of the database. The subscripts in brackets after the data frame refer to row and column numbers. Check out Spoetry for a complete description.

newdf <- mydf[,1:3]

Or, you can choose specific rows.

newdf <- mydf[1:3,]

And these subscripts can also be logical tests, such as choosing rows that contain a particular value, or factors with a desired value.

What do you want to do with the chunks left over? Do you need to perform the same operation on each chunk of the database? Then you'll want to ensure that the subsets of the data frame end up in a convenient object, such as a list, that will help you perform the same command on each chunk of the data frame.

You can try this,

UPDATE *tableName* SET *field1* = *your_data*, *field2* = *your_data* ... WHERE 1 = 1;

Well in your case if you want to update your online_status to some value, you can try this,

UPDATE thisTable SET online_status = 'Online' WHERE 1 = 1;

Hope it helps. :D

Typescript projects (I have typescript in SFC vue components), need to set resolveJsonModule compiler option to true.

In tsconfig.json:

{
  "compilerOptions": {
    ...
    "resolveJsonModule": true,
    ...
  },
  ...
}

Happy coding :)

(Source https://www.typescriptlang.org/docs/handbook/compiler-options.html)

Well, even in Java 8, long and int are still signed, only some methods treat them as if they were unsigned. If you want to write unsigned long literal like that, you can do

static long values = Long.parseUnsignedLong("18446744073709551615");

public static void main(String[] args) {
    System.out.println(values); // -1
    System.out.println(Long.toUnsignedString(values)); // 18446744073709551615
}

import numpy as np
array_ = np.array([[1,2,3]])
add_row = np.array([[4,5,6]])

array_ = np.concatenate((array_, add_row), axis=0)

You're storing the .Text properties of the textboxes directly into the database, this doesn't work. The .Text properties are Strings (i.e. simple text) and not typed as DateTime instances. Do the conversion first, then it will work.

Do this for each date parameter:

Dim bookIssueDate As DateTime = DateTime.ParseExact( txtBookDateIssue.Text, "dd/MM/yyyy", CultureInfo.InvariantCulture ) cmd.Parameters.Add( New OleDbParameter("@Date_Issue", bookIssueDate ) ) 

Note that this code will crash/fail if a user enters an invalid date, e.g. "64/48/9999", I suggest using DateTime.TryParse or DateTime.TryParseExact, but implementing that is an exercise for the reader.

You want to write a function (a recursive function is easiest, but can easily run out of stack space on deep directories) that will enumerate the children of a directory. If you find a child that is a directory, you recurse on that. Otherwise, you delete the files inside. When you are done, the directory is empty and you can remove it via the syscall.

To enumerate directories on Unix, you can use opendir(), readdir(), and closedir(). To remove you use rmdir() on an empty directory (i.e. at the end of your function, after deleting the children) and unlink() on a file. Note that on many systems the d_type member in struct dirent is not supported; on these platforms, you will have to use stat() and S_ISDIR(stat.st_mode) to determine if a given path is a directory.

On Windows, you will use FindFirstFile()/FindNextFile() to enumerate, RemoveDirectory() on empty directories, and DeleteFile() to remove files.

Here's an example that might work on Unix (completely untested):

int remove_directory(const char *path) {
   DIR *d = opendir(path);
   size_t path_len = strlen(path);
   int r = -1;

   if (d) {
      struct dirent *p;

      r = 0;
      while (!r && (p=readdir(d))) {
          int r2 = -1;
          char *buf;
          size_t len;

          /* Skip the names "." and ".." as we don't want to recurse on them. */
          if (!strcmp(p->d_name, ".") || !strcmp(p->d_name, ".."))
             continue;

          len = path_len + strlen(p->d_name) + 2; 
          buf = malloc(len);

          if (buf) {
             struct stat statbuf;

             snprintf(buf, len, "%s/%s", path, p->d_name);
             if (!stat(buf, &statbuf)) {
                if (S_ISDIR(statbuf.st_mode))
                   r2 = remove_directory(buf);
                else
                   r2 = unlink(buf);
             }
             free(buf);
          }
          r = r2;
      }
      closedir(d);
   }

   if (!r)
      r = rmdir(path);

   return r;
}

Most regular expression engines support "counter part" escape sequences. That is, for \s (white-space) there's its counter part \S (non-white-space).

Using this, you can check, if there is at least one non-white-space character with ^\S+$.

PCRE for PHP has several of these escape sequences.

It worked for me. Go to Tools-> Options -> Debugger -> Native and check the Load DLL exports. Hope this helps

To get the list of stashes that are still in your repository, but not reachable any more:

git fsck --unreachable | grep commit | cut -d" " -f3 | xargs git log --merges --no-walk --grep=WIP

If you gave a title to your stash, replace "WIP" in -grep=WIP at the end of the command with a part of your message, e.g. -grep=Tesselation.

The command is grepping for "WIP" because the default commit message for a stash is in the form WIP on mybranch: [previous-commit-hash] Message of the previous commit.

Try this very simple:

            var cookieExist = $.cookie("status");
            if(cookieExist == "null" ){
                alert("Cookie Is Null");

            }

If you cannot put them into one container, then you have to write code to change checked state of each RadioButton:

private void rbDataSourceFile_CheckedChanged(object sender, EventArgs e)
{
    rbDataSourceNet.Checked = !rbDataSourceFile.Checked;
}

private void rbDataSourceNet_CheckedChanged(object sender, EventArgs e)
{
  rbDataSourceFile.Checked = !rbDataSourceNet.Checked;
}

unlinkr function recursively deletes all the folders and files in given path by making sure it doesn't delete the script itself.

function unlinkr($dir, $pattern = "*") {
    // find all files and folders matching pattern
    $files = glob($dir . "/$pattern"); 

    //interate thorugh the files and folders
    foreach($files as $file){ 
    //if it is a directory then re-call unlinkr function to delete files inside this directory     
        if (is_dir($file) and !in_array($file, array('..', '.')))  {
            echo "<p>opening directory $file </p>";
            unlinkr($file, $pattern);
            //remove the directory itself
            echo "<p> deleting directory $file </p>";
            rmdir($file);
        } else if(is_file($file) and ($file != __FILE__)) {
            // make sure you don't delete the current script
            echo "<p>deleting file $file </p>";
            unlink($file); 
        }
    }
}

if you want to delete all files and folders where you place this script then call it as following

//get current working directory
$dir = getcwd();
unlinkr($dir);

if you want to just delete just php files then call it as following

unlinkr($dir, "*.php");

you can use any other path to delete the files as well

unlinkr("/home/user/temp");

This will delete all files in home/user/temp directory.

Hello World!
You see, the main question while using hidden input is what kind of data you want to pass? I will assume that you are trying to pass the user ID.
Which is not a really good idea to pass it here because field() method will generate input and the value will be shown to user as we can't hide html from the users browser. This if you really care about security of your website.

please check this link, and you will see that it's impossible to hide value attribute from users to see.

so what to do then?

See, this is the core of OOP in PHP. and I quote from Matt Zandstr in his great book PHP Objects, Patterns, and Practice fifth edition

I am still stuck with a great deal of unwanted flexibility, though. I rely on the client coder to change a ShopProduct object’s properties from their default values. This is problematic in two ways. First, it takes five lines to properly initialize a ShopProduct object, and no coder will thank you for that. Second, I have no way of ensuring that any of the properties are set when a ShopProduct object is initialized. What I need is a method that is called automatically when an object is instantiated from a class.

Please check this example of using __construct() method which is mentioned in his book too.

     class ShopProduct { 
       public $title;   
       public $producerMainName;  
       public $producerFirstName;  
       public $price = 0;
    
       public function __construct($title,$firstName,$mainName,$price) {
            $this->title = $title;
            $this->producerFirstName = $firstName;  
            $this->producerMainName = $mainName; 
            $this->price = $price;
    }
 }
     

$product1 = new ShopProduct("My Antonia","Willa","Cather",5.99 );
print "author: {$product1->getProducer()}\n";

This produces the following:

author: Willa Cather

Class Car {
  private $user_id;
//.. your properties

  public function __construct($title,$firstName,$mainName,$price){
     $this->user_id = \Yii::$app->user->id;
    //..Your magic

   }
}

The field nbytes will give you the size in bytes of all the elements of the array in a numpy.array:

size_in_bytes = my_numpy_array.nbytes

Notice that this does not measures "non-element attributes of the array object" so the actual size in bytes can be a few bytes larger than this.

Check the file which you have selected in the request.

For me i was getting the error because the file was not present in the system, as i have imported the request from some other machine.

I think you can adapt the function to substract the two timestamps:

return  EXTRACT(MINUTE FROM 
  TO_TIMESTAMP(to_char(p_date1,'DD-MON-YYYY HH:MI:SS'),'DD-MON-YYYY HH24:MI:SS')
-
  TO_TIMESTAMP(to_char(p_date2,'DD-MON-YYYY HH:MI:SS'),'DD-MON-YYYY HH24:MI:SS')
);

I think you could simplify it by just using CAST(p_date as TIMESTAMP).

return  EXTRACT(MINUTE FROM cast(p_date1 as TIMESTAMP) - cast(p_date2 as TIMESTAMP));

Remember dates and timestamps are big ugly numbers inside Oracle, not what we see in the screen; we don't need to tell him how to read them. Also remember timestamps can have a timezone defined; not in this case.

window.print();  

unless you mean a custom looking popup.

I know its quite late to answer this, but I guess it will help anyone ahead.

Well using CSS3 FlexBox. It can be acheived. Make you header as display:flex and divide its entire width into 3 parts. In the first part I have placed the logo, the searchbar in second part and buttons container in last part. apply justify-content: between to the header container and flex-grow:1 to the searchbar. That's it. The sample code is below.

#header {_x000D_
  background-color: #323C3E;_x000D_
  justify-content: space-between;_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
#searchBar, img{_x000D_
  align-self: center;_x000D_
}_x000D_
_x000D_
#searchBar{_x000D_
  flex-grow:1;_x000D_
  background-color: orange;_x000D_
  padding: 10px;_x000D_
}_x000D_
_x000D_
#searchBar input {_x000D_
  width: 100%;_x000D_
}_x000D_
_x000D_
.button {_x000D_
  padding: 22px;_x000D_
}_x000D_
_x000D_
.buttonsHolder{_x000D_
  display:flex;_x000D_
}

<div id="header" class="d-flex justify-content-between">_x000D_
    <img src="img/logo.png" />_x000D_
    <div id="searchBar">_x000D_
      <input type="text" />_x000D_
    </div>_x000D_
    <div class="buttonsHolder">_x000D_
      <div class="button orange inline" id="myAccount">_x000D_
        My Account_x000D_
      </div>_x000D_
      <div class="button red inline" id="basket">_x000D_
        Basket (2)_x000D_
      </div>_x000D_
    </div>_x000D_
</div>

You can do this:

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

You can use this

     var fs = require('fs');
     var myCss = {
         style : fs.readFileSync('./style.css','utf8');
     };

     app.get('/', function(req, res){
       res.render('index.ejs', {
       title: 'My Site',
       myCss: myCss
      });
     });

put this on template

   <%- myCss.style %>

just build style.css

  <style>
    body { 
     background-color: #D8D8D8;
     color: #444;
   }
  </style>

I try this for some custom css. It works for me

While the solutions here are workable, more recent technology has made for what I think is a better solution. CSS Grid Layout allows us to structure a more elegant solution.

The CSS below provides a 2-column "settings" structure, where the first column is expected to be a right-aligned label, followed by some content in the second column. More complicated content can be presented in the second column by wrapping it in a <div>.

[As a side-note: I use CSS to add the ':' that trails each label, as this is a stylistic element - my preference.]

/* CSS */_x000D_
_x000D_
div.settings {_x000D_
    display:grid;_x000D_
    grid-template-columns: max-content max-content;_x000D_
    grid-gap:5px;_x000D_
}_x000D_
div.settings label       { text-align:right; }_x000D_
div.settings label:after { content: ":"; }

<!-- HTML -->_x000D_
_x000D_
<div class="settings">_x000D_
    <label>Label #1</label>_x000D_
    <input type="text" />_x000D_
_x000D_
    <label>Long Label #2</label>_x000D_
    <span>Display content</span>_x000D_
_x000D_
    <label>Label #3</label>_x000D_
    <input type="text" />_x000D_
</div>

If you are looking to checkout master branch for each submodule -- you can use the following command for that purpose:

git submodule foreach git checkout master

If you know the width of the child element you are animating, you can use and animate a margin offset as well. For example, this will animate from left:0 to right:0

CSS:

.parent{
width:100%;
position:relative;
}

#itemToMove{
position:absolute;
width:150px;
right:100%;
margin-right:-150px;
}

Javascript:

$( "#itemToMove" ).animate({
"margin-right": "0",
"right": "0"
}, 1000 );

The following solutions are applicable since spark 1.5 :

For lower than :

// filter data where the date is lesser than 2015-03-14
data.filter(data("date").lt(lit("2015-03-14")))      

For greater than :

// filter data where the date is greater than 2015-03-14
data.filter(data("date").gt(lit("2015-03-14"))) 

For equality, you can use either equalTo or === :

data.filter(data("date") === lit("2015-03-14"))

If your DataFrame date column is of type StringType, you can convert it using the to_date function :

// filter data where the date is greater than 2015-03-14
data.filter(to_date(data("date")).gt(lit("2015-03-14"))) 

You can also filter according to a year using the year function :

// filter data where year is greater or equal to 2016
data.filter(year($"date").geq(lit(2016))) 

Java doesn't natively allow building of an exe, that would defeat its purpose of being cross-platform.

AFAIK, these are your options:

1. Make a runnable JAR. If the system supports it and is configured appropriately, in a GUI, double clicking the JAR will launch the app. Another option would be to write a launcher shell script/batch file which will start your JAR with the appropriate parameters

2. There also executable wrappers - see How can I convert my Java program to an .exe file?

Since beta.16 the parameters are not passed as array to the transform() method anymore but instead as individual parameters:

{{ myData | date:'fullDate':'arg1':'arg2' }}


export class DatePipe implements PipeTransform {    
  transform(value:any, arg1:any, arg2:any):any {
        ...
}

https://github.com/angular/angular/blob/master/CHANGELOG.md#200-beta16-2016-04-26

pipes now take a variable number of arguments, and not an array that contains all arguments.

To pass XML content, you need to wrap the content in a Reader, and unmarshal that instead:

JAXBContext jaxbContext = JAXBContext.newInstance(Person.class);
Unmarshaller unmarshaller = jaxbContext.createUnmarshaller();

StringReader reader = new StringReader("xml string here");
Person person = (Person) unmarshaller.unmarshal(reader);

If you mean using a literal, you simply have to create a binary string:

insert into Files (FileId, FileData) values (1, 0x010203040506)

And you will have a record with a six byte value for the FileData field.

You indicate in the comments that you want to just specify the file name, which you can't do with SQL Server 2000 (or any other version that I am aware of).

You would need a CLR stored procedure to do this in SQL Server 2005/2008 or an extended stored procedure (but I'd avoid that at all costs unless you have to) which takes the filename and then inserts the data (or returns the byte string, but that can possibly be quite long).

In regards to the question of only being able to get data from a SP/query, I would say the answer is yes, because if you give SQL Server the ability to read files from the file system, what do you do when you aren't connected through Windows Authentication, what user is used to determine the rights? If you are running the service as an admin (God forbid) then you can have an elevation of rights which shouldn't be allowed.

I couldn't find a rationale by the original developers this quickly, but I can give you an educated guess based on a few years of Git experience.

No, not every branch is something you want to push to the outside world. It might represent a private experiment.

Moreover, where should git push send all the branches? Git can work with multiple remotes and you may want to have different sets of branches on each. E.g. a central project GitHub repo may have release branches; a GitHub fork may have topic branches for review; and a local Git server may have branches containing local configuration. If git push would push all branches to the remote that the current branch tracks, this kind of scheme would be easy to screw up.

@Petr Mensik & kensen john

Thanks, I could not used the page directive because I have to set a different content type according to some URL parameter. I will paste my code here since it's something quite common with JSON:

    <%
        String callback = request.getParameter("callback");
        response.setCharacterEncoding("UTF-8");
        if (callback != null) {
            // Equivalent to: <@page contentType="text/javascript" pageEncoding="UTF-8">
            response.setContentType("text/javascript");
        } else {
            // Equivalent to: <@page contentType="application/json" pageEncoding="UTF-8">
            response.setContentType("application/json");
        }

        [...]

        String output = "";

        if (callback != null) {
            output += callback + "(";
        }

        output += jsonObj.toString();

        if (callback != null) {
            output += ");";
        }
    %>
    <%=output %>

When callback is supplied, returns:

    callback({...JSON stuff...});

with content-type "text/javascript"

When callback is NOT supplied, returns:

    {...JSON stuff...}

with content-type "application/json"

It is possible with inline javascript onkeyup="this.setAttribute('value', this.value);" & input:not([value=""]):not(:focus):invalid

Demo: http://jsfiddle.net/mhsyfvv9/

input:not([value=""]):not(:focus):invalid{_x000D_
  background-color: tomato;_x000D_
}

<input _x000D_
  type="email" _x000D_
  value="" _x000D_
  placeholder="valid mail" _x000D_
  onchange="this.setAttribute('value', this.value);" />

Do not use Bitmap.Config.ARGB_8888

Instead use int w = WIDTH_PX, h = HEIGHT_PX;

Bitmap.Config conf = Bitmap.Config.ARGB_4444; // see other conf types
Bitmap bmp = Bitmap.createBitmap(w, h, conf); // this creates a MUTABLE bitmap
Canvas canvas = new Canvas(bmp);

// ready to draw on that bitmap through that canvas

ARGB_8888 can land you in OutOfMemory issues when dealing with more bitmaps or large bitmaps. Or better yet, try avoiding usage of ARGB option itself.

In azure data studio press "cmd+shift+p" and type "intellisense", then you will see an option to refresh intellisense cache.

There is three way to transaction animation in fragment.

Transitions

So need to use one of the built-in Transitions, use the setTranstion() method:

getSupportFragmentManager()
        .beginTransaction()
        .setTransition( FragmentTransaction.TRANSIT_FRAGMENT_OPEN )
        .show( m_topFragment )
        .commit()

Custom Animations

You can also customize the animation by using the setCustomAnimations() method:

getSupportFragmentManager()
        .beginTransaction()
        .setCustomAnimations( R.anim.slide_up, 0, 0, R.anim.slide_down)
        .show( m_topFragment )
        .commit()

slide_up.xml

<?xml version="1.0" encoding="utf-8"?>
<objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:propertyName="translationY"
        android:valueType="floatType"
        android:valueFrom="1280"
        android:valueTo="0"
        android:duration="@android:integer/config_mediumAnimTime"/>

slide_down.xml

<?xml version="1.0" encoding="utf-8"?>
<objectAnimator
        xmlns:android="http://schemas.android.com/apk/res/android"
        android:interpolator="@android:anim/accelerate_decelerate_interpolator"
        android:propertyName="translationY"
        android:valueType="floatType"
        android:valueFrom="0"
        android:valueTo="1280"
        android:duration="@android:integer/config_mediumAnimTime"/>

Multiple Animations

Finally, It's also possible to kick-off multiple fragment animations in a single transaction. This allows for a pretty cool effect where one fragment is sliding up and the other slides down at the same time:

getSupportFragmentManager()
        .beginTransaction()
        .setCustomAnimations( R.anim.abc_slide_in_top, R.anim.abc_slide_out_top ) // Top Fragment Animation
        .show( m_topFragment )
        .setCustomAnimations( R.anim.abc_slide_in_bottom, R.anim.abc_slide_out_bottom ) // Bottom Fragment Animation
        .show( m_bottomFragment )
        .commit()

To more detail you can visit URL

Note:- You can check animation according to your requirement because above may be have issue.

Is the maximum recommended title length really 50?

I have believed this for years, but as I just noticed the documentation of "git commit" actually states

$ git help commit | grep -C 1 50
      Though not required, it’s a good idea to begin the commit message with
      a single short (less than 50 character) line summarizing the change,
      followed by a blank line and then a more thorough description. The text

$  git version
git version 2.11.0

One could argue that "less then 50" can only mean "no longer than 49".

How are you opening the rendered Markdown?

If you host it over HTTP, i.e. you access it via http:// or https://, most modern browsers will refuse to open local links, e.g. with file://. This is a security feature:

For security purposes, Mozilla applications block links to local files (and directories) from remote files. This includes linking to files on your hard drive, on mapped network drives, and accessible via Uniform Naming Convention (UNC) paths. This prevents a number of unpleasant possibilities, including:

• Allowing sites to detect your operating system by checking default installation paths
• Allowing sites to exploit system vulnerabilities (e.g., C:\con\con in Windows 95/98)
• Allowing sites to detect browser preferences or read sensitive data

There are some workarounds listed on that page, but my recommendation is to avoid doing this if you can.

Try this

alter table TableName 
 add constraint df_ConstraintNAme 
 default getutcdate() for [Date]

example

create table bla (id int)

alter table bla add constraint dt_bla default 1 for id



insert bla default values

select * from bla

also make sure you name the default constraint..it will be a pain in the neck to drop it later because it will have one of those crazy system generated names...see also How To Name Default Constraints And How To Drop Default Constraint Without A Name In SQL Server

function _formatDatetime(date: Date, format: string) {
   const _padStart = (value: number): string => value.toString().padStart(2, '0');
return format
    .replace(/yyyy/g, _padStart(date.getFullYear()))
    .replace(/dd/g, _padStart(date.getDate()))
    .replace(/mm/g, _padStart(date.getMonth() + 1))
    .replace(/hh/g, _padStart(date.getHours()))
    .replace(/ii/g, _padStart(date.getMinutes()))
    .replace(/ss/g, _padStart(date.getSeconds()));
}
function isValidDate(d: Date): boolean {
    return !isNaN(d.getTime());
}
export function formatDate(date: any): string {
    var datetime = new Date(date);
    return isValidDate(datetime) ? _formatDatetime(datetime, 'yyyy-mm-dd hh:ii:ss') : '';
}

Complete Solution in JavaScript for all browsers

The code above and most of the solutions are perfect. However, I think the most liked one "short answer" which is incomplete.

So here's the entire answer. in JavaScript with native Support for IE 7 as well.

var form = document.getElementById("testForm");
form.addEventListener("submit",function(e){e.preventDefault(); return false;});

This solution will now prevent the user from submit using the enter Key and will not reload the page, or take you to the top of the page, if your form is somewhere below.

private void buttonNextForm(object sender, EventArgs e)
{
    NextForm nf = new NextForm();//Object of the form that you want to open
    this.hide();//Hide cirrent form.
    nf.ShowModel();//Display the next form window
    this.Close();//While closing the NextForm, control will come again and will close this form as well
}

The trick is to add environment variables to sudoers file via sudo visudo command and add these lines:

Defaults env_keep += "ftp_proxy http_proxy https_proxy no_proxy"

taken from ArchLinux wiki.

For Ubuntu 14, you need to specify in separate lines as it returns the errors for multi-variable lines:

Defaults  env_keep += "http_proxy"
Defaults  env_keep += "https_proxy"
Defaults  env_keep += "HTTP_PROXY"
Defaults  env_keep += "HTTPS_PROXY"

The following will work independent of your database privileges:

select * from all_triggers
where table_name = 'YOUR_TABLE'

The following alternate options may or may not work depending on your assigned database privileges:

select * from DBA_TRIGGERS

or

select * from USER_TRIGGERS

Great then. Let's create a simple function that takes an array and prints our an ordered listview/list inside a div tag.

Step 1: Let's say you have an div with "contentSectionID" id.<div id="contentSectionID"></div>

Step 2: We then create our javascript function that returns a list component and takes in an array:

function createList(spacecrafts){

var listView=document.createElement('ol');

for(var i=0;i<spacecrafts.length;i++)
{
    var listViewItem=document.createElement('li');
    listViewItem.appendChild(document.createTextNode(spacecrafts[i]));
    listView.appendChild(listViewItem);
}

return listView;
}

Step 3: Finally we select our div and create a listview in it:

document.getElementById("contentSectionID").appendChild(createList(myArr));

you can get the data from the XML by using "simplexml_load_file" Function. Please refer this link

http://php.net/manual/en/function.simplexml-load-file.php

$url = "http://maps.google.com/maps/api/directions/xml?origin=Quentin+Road+Brooklyn%2C+New+York%2C+11234+United+States&destination=550+Madison+Avenue+New+York%2C+New+York%2C+10001+United+States&sensor=false";
$xml = simplexml_load_file($url);
print_r($xml);

Just so others who have configured their apps like mine benefit from what I went through...

None of the above solutions worked for me because I have a ./config directory just under my project base with 2 files:

application.properties
application-dev.properties

In application.properties I have:

spring.profiles.active = dev  # set my default profile to 'dev'

In application-dev.properties I have:

server_host = localhost
server_port = 8080

This is so when I run my fat jar from the CLI the *.properties files will be read from the ./config dir and all is good.

Well, it turns out that these properties files completely override the webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT setting in @SpringBootTest in my Spock specs. No matter what I tried, even with webEnvironment set to RANDOM_PORT Spring would always startup the embedded Tomcat container on port 8080 (or whatever value I'd set in my ./config/*.properties files).

The ONLY way I was able to overcome this was by adding an explicit properties = "server_port=0" to the @SpringBootTest annotation in my Spock integration specs:

@SpringBootTest (webEnvironment = SpringBootTest.WebEnvironment.RANDOM_PORT, properties = "server_port=0")

Then, and only then did Spring finally start to spin up Tomcat on a random port. IMHO this is a Spring testing framework bug, but I'm sure they'll have their own opinion on this.

Hope this helped someone.

I have a Samsung Galaxy and I had the same issue as you. Here's how to fix it:

In device manager on your Windows PC, even though it might say the USB drivers are installed correctly, there may exist corruption.

I went into device manager and uninstalled SAMSUNG Android USB Composite Device and made sure to check the box 'delete driver software'. Now the device will have an exclamation mark etc. I right clicked and installed the driver again (refresh copy). This finally made adb acknowledge my phone as an emulator.

As others noted, for Nexus 4, you can also try this fix.

Easy one! "\t"

Edit: In fact, here's something official: Escape Sequences

function ConvertDateFromDiv(divTimeStr) {
    //eg:-divTimeStr=18/03/2013 12:53:00
    var tmstr = divTimeStr.toString().split(' '); //'21-01-2013 PM 3:20:24'
    var dt = tmstr[0].split('/');
    var str = dt[2] + "/" + dt[1] + "/" + dt[0] + " " + tmstr[1]; //+ " " + tmstr[1]//'2013/01/20 3:20:24 pm'
    var time = new Date(str);
    if (time == "Invalid Date") {
        time = new Date(divTimeStr);
    }
    return time;
}

It is not possible because they are executed in different environments (JSP at server side, JavaScript at client side). So they are not executed in the sequence you see in your code.

var val1 = document.getElementById('userName').value; 

<c:set var="user" value=""/>  // how do i set val1 here? 

Here JSTL code is executed at server side and the server sees the JavaScript/Html codes as simple texts. The generated contents from JSTL code (if any) will be rendered in the resulting HTML along with your other JavaScript/HTML codes. Now the browser renders HTML along with executing the Javascript codes. Now remember there is no JSTL code available for the browser.

Now for example,

<script type="text/javascript">
<c:set var="message" value="Hello"/> 
var message = '<c:out value="${message}"/>';
</script>

Now for the browser, this content is rendered,

<script type="text/javascript">
var message = 'Hello';
</script>

Hope this helps.

I tweaked the previous answers by using the --sort flag and added some color/formatting:

git for-each-ref --format='%(color:cyan)%(authordate:format:%m/%d/%Y %I:%M %p)    %(align:25,left)%(color:yellow)%(authorname)%(end) %(color:reset)%(refname:strip=3)' --sort=authordate refs/remotes

Normally, mutt sets the From: header based on the from configuration variable you set in ~/.muttrc:

set from="Fubar <foo@bar>"

If this is not set, mutt uses the EMAIL environment variable by default. In which case, you can get away with calling mutt like this on the command line (as opposed to how you showed it in your comment):

EMAIL="foo@bar" mutt -s '$MailSubject' -c "abc@def"

However, if you want to be able to edit the From: header while composing, you need to configure mutt to allow you to edit headers first. This involves adding the following line in your ~/.muttrc:

set edit_headers=yes

After that, next time you open up mutt and are composing an E-mail, your chosen text editor will pop up containing the headers as well, so you can edit them. This includes the From: header.

Of course, never fails. Found the solution about a minute after posting the above question... solution for those that may have had the same issue:

ContextWrapper.getFilesDir()

Found here.

I encountered the same problem attempting to setup Android Studio from work. Running as admin didn't solve my problem, and I don't have direct access to proxy / firewall settings. In the end I resolved the issue by using the Android SDK Manager and installing the proper packages. A few of the package names and error messages (from studio install failure) didn't match up directly but a quick Google search showed me the light.

Hope this helps!

Below function will strip the empty spces and return the strings without quotes. If there are no quotes then it will return same string(stripped)

def removeQuote(str):
str = str.strip()
if re.search("^[\'\"].*[\'\"]$",str):
    str = str[1:-1]
    print("Removed Quotes",str)
else:
    print("Same String",str)
return str

Simple:

Use <section>.

Another possible reason for this error for the Mega 2560 is if your code has three exclamation marks in a row. Perhaps in a recently added string.

3 bang marks in a row causes the Mega 2560 bootloader to go into Monitor mode from which it can not finish programming.

"!!!" <--- breaks Mega 2560 bootloader.

To fix, unplug the Arduino USB to reset the COM port and then recompile with only two exclamation points or with spaces between or whatever. Then reconnect the Arduino and program as usual.

Yes, this bit me yesterday and today I tracked down the culprit. Here is a link with more information: http://forum.arduino.cc/index.php?topic=132595.0

you can just use

ls > filenames.txt

(usually, start a shell by using "Terminal", or "shell", or "Bash".) You may need to use cd to go to that folder first, or you can ls ~/docs > filenames.txt

In Html use:

• Some <b>text</b> that I want emboldened.
• Some <strong>text</strong> that I want emboldened.

In CSS use:

• Some <span style="font-weight:bold">text</span> that I want emboldened.

That's how I achieved it, which is not visible (HORRIBLE SOUND....)

<!-- horrible is your mp3 file name any other supported format.-->
<audio controls autoplay hidden="" src="horrible.mp3" type ="audio/mp3"">your browser does not support Html5</audio>

I did a combination of what others have posted. Its simple and smooth

 $('#myButton').click(function(){
        $('html, body').animate({
            scrollTop: $('#scroll-to-this-element').position().top },
            1000
        );
    });

These are utf-8 encoded characters. Use utf8_decode() to convert them to normal ISO-8859-1 characters.

Your reader variable is an iterable, by looping over it you retrieve the rows.

To make it skip one item before your loop, simply call next(reader, None) and ignore the return value.

You can also simplify your code a little; use the opened files as context managers to have them closed automatically:

with open("tmob_notcleaned.csv", "rb") as infile, open("tmob_cleaned.csv", "wb") as outfile:
   reader = csv.reader(infile)
   next(reader, None)  # skip the headers
   writer = csv.writer(outfile)
   for row in reader:
       # process each row
       writer.writerow(row)

# no need to close, the files are closed automatically when you get to this point.

If you wanted to write the header to the output file unprocessed, that's easy too, pass the output of next() to writer.writerow():

headers = next(reader, None)  # returns the headers or `None` if the input is empty
if headers:
    writer.writerow(headers)

Adding to the above-accepted answer so that it helps those who are using tensorflow 2.0

import tensorflow as tf

# some data
c1 = tf.constant([[1, 1, 1], [2, 2, 2]], dtype=tf.float32)
c2 = tf.constant([[2, 2, 2], [3, 3, 3]], dtype=tf.float32)
c3 = tf.constant([[3, 3, 3], [4, 4, 4]], dtype=tf.float32)

# bake layers x1, x2, x3
x1 = tf.keras.layers.Dense(10)(c1)
x2 = tf.keras.layers.Dense(10)(c2)
x3 = tf.keras.layers.Dense(10)(c3)

# merged layer y1
y1 = tf.keras.layers.Concatenate(axis=1)([x1, x2])

# merged layer y2
y2 = tf.keras.layers.Concatenate(axis=1)([y1, x3])

# print info
print("-"*30)
print("x1", x1.shape, "x2", x2.shape, "x3", x3.shape)
print("y1", y1.shape)
print("y2", y2.shape)
print("-"*30)

Result:

------------------------------
x1 (2, 10) x2 (2, 10) x3 (2, 10)
y1 (2, 20)
y2 (2, 30)
------------------------------

From the documentation for ast.literal_eval():

Safely evaluate an expression node or a string containing a Python expression. The string or node provided may only consist of the following Python literal structures: strings, numbers, tuples, lists, dicts, booleans, and None.

Decimal isn't on the list of things allowed by ast.literal_eval().

Since the class is added dynamically, you need to use event delegation to register the event handler

$(document).on('click', "a.tabclick", function() {
    var liId = $(this).parent("li").attr("id");
    alert(liId);        
});

You miss the from clause

SELECT *  from TCCAWZTXD.TCC_COIL_DEMODATA WHERE CURRENT_INSERTTIME  BETWEEN(CURRENT_TIMESTAMP)-5 minutes AND CURRENT_TIMESTAMP

I think Todd is correct, but I think there's one other thing you should consider. You can reliably get the home directory from the JVM at runtime, and then you can create files objects relative to that location. It's not that much more trouble, and it's something you'll appreciate if you ever move to another computer or operating system.

File homedir = new File(System.getProperty("user.home"));
File fileToRead = new File(homedir, "java/ex.txt");

Although it doesn't precisely answer the question, I landed here when searching for a way to get the collection of elements (potentially different tag names) that simply had a given attribute name (without filtering by attribute value). I found that the following worked well for me:

$("*[attr-name]")

Hope that helps somebody who happens to land on this page looking for the same thing that I was :).

Update: It appears that the asterisk is not required, i.e. based on some basic tests, the following seems to be equivalent to the above (thanks to Matt for pointing this out):

$("[attr-name]")

map(lambda s: s.strip(), mylist) would be a little better than explicitly looping.
Or for the whole thing at once:

map(lambda s:s.strip(), string.split(','))

That's basically everything you need.

That will work just fine. You can export an entire calendar with File > Export…, or individual events by dragging them to the Finder.

iCalendar (.ics) files are human-readable, so you can always pop it open in a text editor to make sure no private events made it in there. They consist of nested sections with start with BEGIN: and end with END:. You'll mostly find VEVENT sections (each of which represents an event) and VTIMEZONE sections, each of which represents a time zone that's referenced from one or more events.

You can compute pairwise cosine similarity on the rows of a sparse matrix directly using sklearn. As of version 0.17 it also supports sparse output:

If you want column-wise cosine similarities simply transpose your input matrix beforehand:

A_sparse.transpose()

Here is the simple logic to find Biggest/Largest Number

Input : 11, 33, 1111, 4, 0 Output : 1111

namespace PurushLogics
{
    class Purush_BiggestNumber
    {
        static void Main()
        {
            int count = 0;
            Console.WriteLine("Enter Total Number of Integers\n");
            count = int.Parse(Console.ReadLine());

            int[] numbers = new int[count];

            Console.WriteLine("Enter the numbers"); // Input 44, 55, 111, 2 Output = "111"
            for (int temp = 0; temp < count; temp++)
            {
                numbers[temp] = int.Parse(Console.ReadLine());
            }

            int largest = numbers[0];
            for (int big = 1; big < numbers.Length; big++)
            {
                if (largest < numbers[big])
                {
                    largest = numbers[big];
                }
            }
            Console.WriteLine(largest);
            Console.ReadKey();
        }
    }
}

• Controller will handle the navigation between the different views. Your mappings request mappings are handled with the help of controller.
• Service interacts directly with the repository where usually the business logic is performed. You can add, delete, remove etc at the service layer

If you have to use a distutils setup.py script, there are some commandline options for forcing an installation destination. See http://docs.python.org/install/index.html#alternate-installation. If this problem repeats, you can setup a distutils configuration file, see http://docs.python.org/install/index.html#inst-config-files.

Setting the PYTHONPATH variable is described in tihos post.

select t1.* from 
(select * from TABLE Where CCC='D' AND DDD='X') as t1,
(select * from TABLE Where CCC<>'D' AND DDD='X') as t2

Another way to do this!

You can use below instead:

DateTime.Now.Ticks

You can use the IGNORE keyword too, example:

 update IGNORE table set primary_field = 'value'...............

Let me answer this question thoroughly, because it's been a source of pain for me for several years and very few people really understand the problem and why it's important for it to be solved. If I were at all responsible for the CSS spec I'd be embarrassed, frankly, for having not addressed this in the last decade.

The Problem

You need to insert markup into an HTML document, and it needs to look a specific way. Furthermore, you do not own this document, so you cannot change existing style rules. You have no idea what the style sheets could be, or what they may change to.

Use cases for this are when you are providing a displayable component for unknown 3rd party websites to use. Examples of this would be:

1. An ad tag
2. Building a browser extension that inserts content
3. Any type of widget

Simplest Fix

Put everything in an iframe. This has it's own set of limitations:

1. Cross Domain limitations: Your content will not have access to the original document at all. You cannot overlay content, modify the DOM, etc.
2. Display Limitations: Your content is locked inside of a rectangle.

If your content can fit into a box, you can get around problem #1 by having your content write an iframe and explicitly set the content, thus skirting around the issue, since the iframe and document will share the same domain.

CSS Solution

I've search far and wide for the solution to this, but there are unfortunately none. The best you can do is explicitly override all possible properties that can be overridden, and override them to what you think their default value should be.

Even when you override, there is no way to ensure a more targeted CSS rule won't override yours. The best you can do here is to have your override rules target as specifically as possible and hope the parent document doesn't accidentally best it: use an obscure or random ID on your content's parent element, and use !important on all property value definitions.

ephemeral is just another name of root volume when you launch Instance from AMI backed from Amazon EC2 instance store

So Everything will be stored on ephemeral.

if you have launched your instance from AMI backed by EBS volume then your instance does not have ephemeral.

I needed to kill processes on different ports so I created a bash script:

killPort() {
  PID=$(echo $(lsof -n -i4TCP:$1) | awk 'NR==1{print $11}')
  kill -9 $PID
}

Just add that to your .bashrc and run it like this:

killPort 8080

You can pass whatever port number you wish

Well, timing to the rescue again. It seems switch is generally faster than if statements. So that, and the fact that the code is shorter/neater with a switch statement leans in favor of switch:

# Simplified to only measure the overhead of switch vs if

test1 <- function(type) {
 switch(type,
        mean = 1,
        median = 2,
        trimmed = 3)
}

test2 <- function(type) {
 if (type == "mean") 1
 else if (type == "median") 2
 else if (type == "trimmed") 3
}

system.time( for(i in 1:1e6) test1('mean') ) # 0.89 secs
system.time( for(i in 1:1e6) test2('mean') ) # 1.13 secs
system.time( for(i in 1:1e6) test1('trimmed') ) # 0.89 secs
system.time( for(i in 1:1e6) test2('trimmed') ) # 2.28 secs

Update With Joshua's comment in mind, I tried other ways to benchmark. The microbenchmark seems the best. ...and it shows similar timings:

> library(microbenchmark)
> microbenchmark(test1('mean'), test2('mean'), times=1e6)
Unit: nanoseconds
           expr  min   lq median   uq      max
1 test1("mean")  709  771    864  951 16122411
2 test2("mean") 1007 1073   1147 1223  8012202

> microbenchmark(test1('trimmed'), test2('trimmed'), times=1e6)
Unit: nanoseconds
              expr  min   lq median   uq      max
1 test1("trimmed")  733  792    843  944 60440833
2 test2("trimmed") 2022 2133   2203 2309 60814430

Final Update Here's showing how versatile switch is:

switch(type, case1=1, case2=, case3=2.5, 99)

This maps case2 and case3 to 2.5 and the (unnamed) default to 99. For more information, try ?switch

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:

Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();

This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.

tl;dr

java.time.LocalDateTime.parse( 
    "04/02/2011 20:27:05" , 
    DateTimeFormatter.ofPattern( "dd/MM/uuuu HH:mm:ss" )
)

java.time

The modern approach uses the java.time classes that supplant the venerable Joda-Time project.

Parse as a LocalDateTime as your input lacks any indicator of time zone or offset-from-UTC.

String input = "04/02/2011 20:27:05" ;
DateTimeFormatter f = DateTimeFormatter.ofPattern( "dd/MM/uuuu HH:mm:ss" ) ;
LocalDateTime ldt = LocalDateTime.parse( input , f ) ;

ldt.toString(): 2011-02-04T20:27:05

Tip: Where possible, use the standard ISO 8601 formats when exchanging date-time values as text rather than format seen here. Conveniently, the java.time classes use the standard formats when parsing/generating strings.

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

On the HTTP Response where you are returning the PDF file, ensure the content disposition header looks like:

Content-Disposition: attachment; filename=quot.pdf;

See content-disposition on the wikipedia MIME page.

Given the following tables..

Domain Table
dom_id | dom_url

Review Table
rev_id | rev_dom_from | rev_dom_for

Try this sql... (It's pretty much the same thing that Stephen Wrighton wrote above) The trick is that you are basically selecting from the domain table twice in the same query and joining the results.

Select d1.dom_url, d2.dom_id from
review r, domain d1, domain d2
where d1.dom_id = r.rev_dom_from
and d2.dom_id = r.rev_dom_for

If you are still stuck, please be more specific with exactly it is that you don't understand.

With Grid

A pretty simpel and modern way is to use display: grid

div {
    border: 1px dotted grey;
}

#outer {
    display: grid;
    place-items: center;
    height: 50px; /* not necessary */
}

<!DOCTYPE html>
<html>
    <head>
    </head>

    <body>
        <div id="outer">
            <div>Foo foo</div>
        </div>
    </body>
</html>

You can as well do this, this will help when you want to modify a view after clicking a recyclerview position item

@Override
public void onClick(View view, int position) {

            View v =  rv_notifications.getChildViewHolder(view).itemView;
            TextView content = v.findViewById(R.id.tv_content);
            content.setText("Helloo");

        }

For me it was changing.

this.name = response.data;

To what computed returns so;

this.$store.state.name = response.data;

EDIT: ASIHTTPRequest has been abandoned by the developer. It's still really good IMO, but you should probably look elsewhere now.

I'd highly recommend using the ASIHTTPRequest library if you are handling HTTPS. Even without https it provides a really nice wrapper for stuff like this and whilst it's not hard to do yourself over plain http, I just think the library is nice and a great way to get started.

The HTTPS complications are far from trivial in various scenarios, and if you want to be robust in handling all the variations, you'll find the ASI library a real help.

Another option:

 $("<p>").html(myContent).text();

try this

<servlet-mapping>
    <servlet-name>default</servlet-name>
    <url-pattern>*.js</url-pattern>
    <url-pattern>*.css</url-pattern>
    <url-pattern>*.ico</url-pattern>
    <url-pattern>*.png</url-pattern>
    <url-pattern>*.jpg</url-pattern>
    <url-pattern>*.htc</url-pattern>
    <url-pattern>*.gif</url-pattern>
</servlet-mapping>    

Edit: This is only valid for the servlet 2.5 spec and up.

To get the files in the classpath :

Resource resource = new ClassPathResource("countries.xml");
File file = resource.getFile();

To read the file onStartup use @PostConstruct:

@Configuration
public class ReadFileOnStartUp {

    @PostConstruct
    public void afterPropertiesSet() throws Exception {

        //Gets the XML file under src/main/resources folder
        Resource resource = new ClassPathResource("countries.xml");
        File file = resource.getFile();
        //Logic to read File.
    }
}

Here is a Small example for reading an XML File on Spring Boot App startup.

for replace all (') in your string, use

.replace(/\'/g,"''")

example:

sample = "St. Mary's and St. John's";
escapedSample = sample.replace(/\'/g,"''")

Came across this question and wanted something more simple... Try the following:

SELECT [processing-instruction(x)]=@Script FOR XML PATH(''),TYPE

Try Ctrl+Alt+U

Also check if the UML plugin is activated (settings -> plugin, settings can be opened by Ctrl+Alt+S

You can test it in this way

Console.WriteLine(DateTime.Now.ToString("tt "));

The output will be like this:

AM

or

PM

• hadoop ERROR : JAVA_HOME is not set

Above error is because of the space in between two words.

Eg: Java located in C:\Program Files\Java --> Space in between Program and files would cause the above problem. If you remove the space, it would not show any error.

If a method (instance or static) only references variables scoped within that method then it is thread safe because each thread has its own stack:

In this instance, multiple threads could call ThreadSafeMethod concurrently without issue.

public class Thing
{
    public int ThreadSafeMethod(string parameter1)
    {
        int number; // each thread will have its own variable for number.
        number = parameter1.Length;
        return number;
    }
}

This is also true if the method calls other class method which only reference locally scoped variables:

public class Thing
{
    public int ThreadSafeMethod(string parameter1)
    {
        int number;
        number = this.GetLength(parameter1);
        return number;
    }

    private int GetLength(string value)
    {
        int length = value.Length;
        return length;
    }
}

If a method accesses any (object state) properties or fields (instance or static) then you need to use locks to ensure that the values are not modified by a different thread.

public class Thing
{
    private string someValue; // all threads will read and write to this same field value

    public int NonThreadSafeMethod(string parameter1)
    {
        this.someValue = parameter1;

        int number;

        // Since access to someValue is not synchronised by the class, a separate thread
        // could have changed its value between this thread setting its value at the start 
        // of the method and this line reading its value.
        number = this.someValue.Length;
        return number;
    }
}

You should be aware that any parameters passed in to the method which are not either a struct or immutable could be mutated by another thread outside the scope of the method.

To ensure proper concurrency you need to use locking.

for further information see lock statement C# reference and ReadWriterLockSlim.

lock is mostly useful for providing one at a time functionality,
ReadWriterLockSlim is useful if you need multiple readers and single writers.

Actually, rebase saves your starting point to ORIG_HEAD so this is usually as simple as:

git reset --hard ORIG_HEAD

However, the reset, rebase and merge all save your original HEAD pointer into ORIG_HEAD so, if you've done any of those commands since the rebase you're trying to undo then you'll have to use the reflog.

If you don't remember the password you set for root and need to reset it, follow these steps:

1. Stop the mysqld server, this varies per install
2. Run the server in safe mode with privilege bypass

sudo mysqld_safe --skip-grant-tables;

3. In a new window connect to the database, set a new password and flush the permissions & quit:

mysql -u root

For MySQL older than MySQL 5.7 use:

UPDATE mysql.user SET Password=PASSWORD('your-password') WHERE User='root';

For MySQL 5.7+ use:

USE mysql;

UPDATE mysql.user SET authentication_string=PASSWORD("your-password") WHERE User='root';

Refresh and quit:

FLUSH PRIVILEGES;

\q

4. Stop the safe mode server and start your regular server back. The new password should work now. Worked like a charm for me :)

One gotcha I ran into today I think is worth pointing out related to this problem: if the url for the ajax call is redirected then the header for content-type: 'multipart/form-data' can be lost.

For example, I was posting to http://server.com/context?param=x

In the network tab of Chrome I saw the correct multipart header for this request but then a 302 redirect to http://server.com/context/?param=x (note the slash after context)

During the redirect the multipart header was lost. Ensure requests are not being redirected if these solutions are not working for you.

If the first segment doesn't start with / it is a relative route. router.navigate needs a relativeTo parameter for relative navigation

Either you make the route absolute:

this.router.navigate(['/foo-content', 'bar-contents', 'baz-content', 'page'], this.params.queryParams)

or you pass relativeTo

this.router.navigate(['../foo-content', 'bar-contents', 'baz-content', 'page'], {queryParams: this.params.queryParams, relativeTo: this.currentActivatedRoute})

You can simply use one of the system dependent end-of-file indicators ( d for Unix/Linux/Ubuntu, z for windows) to make the while statement false. This should get you out of the loop nicely. :)

You call PowerShell functions without the parentheses and without using the comma as a separator. Try using:

test "ABC" "DEF"

In PowerShell the comma (,) is an array operator, e.g.

$a = "one", "two", "three"

It sets $a to an array with three values.

Given a dataset

df <- data.frame( sex = c('M', 'M', 'F', 'F', 'M'), 
                  occupation = c('analyst', 'dentist', 'dentist', 'analyst', 'cook') )

you can subset rows

df[df$sex == 'M',] # To get all males
df[df$occupation == 'analyst',] # All analysts

etc.

If you want to get number of rows, just call the function nrow such as

nrow(df[df$sex == 'M',])

This way:

 $instance = new Functions(); // create an instance (object) of functions class
 $instance->filter($data); // now call it

Method 1 : Using jQuery Ajax Get call (partial page update).

Suitable for when you need to retrieve jSon data from database.

Controller's Action Method

[HttpGet]
public ActionResult Foo(string id)
{
    var person = Something.GetPersonByID(id);
    return Json(person, JsonRequestBehavior.AllowGet);
}

Jquery GET

function getPerson(id) {
    $.ajax({
        url: '@Url.Action("Foo", "SomeController")',
        type: 'GET',
        dataType: 'json',
        // we set cache: false because GET requests are often cached by browsers
        // IE is particularly aggressive in that respect
        cache: false,
        data: { id: id },
        success: function(person) {
            $('#FirstName').val(person.FirstName);
            $('#LastName').val(person.LastName);
        }
    });
}

Person class

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Method 2 : Using jQuery Ajax Post call (partial page update).

Suitable for when you need to do partial page post data into database.

Post method is also same like above just replace [HttpPost] on Action method and type as post for jquery method.

For more information check Posting JSON Data to MVC Controllers Here

Method 3 : As a Form post scenario (full page update).

Suitable for when you need to save or update data into database.

View

@using (Html.BeginForm("SaveData","ControllerName", FormMethod.Post))
{        
    @Html.TextBoxFor(model => m.Text)
    
    <input type="submit" value="Save" />
}

Action Method

[HttpPost]
public ActionResult SaveData(FormCollection form)
    {
        // Get movie to update
        return View();
   }

Method 4 : As a Form Get scenario (full page update).

Suitable for when you need to Get data from database

Get method also same like above just replace [HttpGet] on Action method and FormMethod.Get for View's form method.

I hope this will help to you.

Officially it's Ctrl+F11 & Ctrl+F12 or KEYPAD 7 & KEYPAD 9.

In practise it's a bit quirky.

1. Specifically it's Left Ctrl+F11 and Left Ctrl+F12 to switch to previous orientation and next orientation respectively.

2. You have to release Ctrl before you can rotate again.

3. KEYPAD 7 and KEYPAD 9 only work with Num Lock OFF (so they're acting as Home & PageUp rather than 7 & 9).

4. The only orientations are vertically upright and rotated one quarter-turn anti-clockwise.

Maybe a bit too much info for such a simple question, but it drove me half-mad finding this out.

Note: This was tested on Android SDK R16 and a very old keyboard, modern keyboards may behave differently.

I am using Windows 7. The below solution works for me!!

**Open** the file JavaC.sublime-build and replace all the code in the file with the code below:

{
 "cmd": ["javac", "$file_name","&&","java", "$file_base_name"],
 "file_regex": "^(...*?):([0-9]*):?([0-9]*)",
 **"path": "C:\\Program Files\\Java\\jdk1.6.0\\bin\\",**
 "selector": "source.java",
 "shell": true
 }

Remember to replace "C:\Program Files\Java\jdk1.6.0\bin\" with the path where you put your jdk. And make sure to add the path of you java JDK to the environment variable "PATH". Refer to bunnyDrug's post to set up the environment variable. Best!!

Node.js is a runtime that compiles and executes javaScript. It can be used to develop application that runs end-to-end in JavaScript i..e both client side and server side uses javascript code unlike most of todays' application with rich client framework (angularJs, extJs) and RESTful server side APIs

I think this is only partially true. Changing the format seems to switch the date to a string object which then has no methods like AddDays to manipulate it. So to make this work, you have to switch it back to a date. For example:

Get-Date (Get-Date).AddDays(-1) -format D

dicts=[
{"name": "Tom", "age": 10},
{"name": "Mark", "age": 5},
{"name": "Pam", "age": 7}
]

from collections import defaultdict
dicts_by_name=defaultdict(list)
for d in dicts:
    dicts_by_name[d['name']]=d

print dicts_by_name['Tom']

#output
#>>>
#{'age': 10, 'name': 'Tom'}

As long as they are of the same type, it's very simple with AddRange:

list2.AddRange(list1);

I think you just need to remove the space. i.e.

$(".myclass[reference=12345]").css('border', '#000 solid 1px');

There is a fiddle here http://jsfiddle.net/xXEHY/

Correct Way would be :

<select id="select-type-basic" [(ngModel)]="status">
    <option *ngFor="let status_item of status_values">
    {{status_item}}
    </option>
</select>

Value Should be avoided inside option if the value is to be dynamic,since that will set the default value of the 'Select field'. Default Selection should be binded with [(ngModel)] and Options should be declared likewise.

status : any = "47";
status_values: any = ["45", "46", "47"];

xDoc.LoadXML("<head><body><Inner> welcome </head> </Inner> <Outer> Bye</Outer>                    
                    </body></head>");

This can be done by two ways according to your Android OS.

1. You can use android:largeHeap="true" in application tag of Android manifest to request a larger heap size, but this will not work on any pre Honeycomb devices.
2. On pre 2.3 devices, you can use the VMRuntime class, but this will not work on Gingerbread and above See below how to do it.

VMRuntime.getRuntime().setMinimumHeapSize(BIGGER_SIZE);

Before Setting HeapSize make sure that you have entered the appropriate size which will not affect other application or OS functionality. Before settings just check how much size your app takes & then set the size just to fulfill your job. Dont use so much of memory otherwise other apps might affect.

I use it for two reasons:

1. I can force a refresh of the icon by adding a query parameter for example ?v=2. like this: <link rel="icon" href="/favicon.ico?v=2" type="image/x-icon" />

2. In case I need to specify the path.

Avoid nullable unique constraints. You can always put the column in a new table, make it non-null and unique and then populate that table only when you have a value for it. This ensures that any key dependency on the column can be correctly enforced and avoids any problems that could be caused by nulls.

I found it useful (where I wanted to ignore line feeds and not change any files) to ignore them in the .eslintrc using linebreak-style as per this answer: https://stackoverflow.com/a/43008668/1129108

module.exports = {
  extends: 'google',
  quotes: [2, 'single'],
  globals: {
    SwaggerEditor: false
  },
  env: {
    browser: true
  },
  rules:{
    "linebreak-style": 0
  }
};

According to Oracle integration of OpenJDK & javaFX will be on Q1-2014 ( see roadmap : http://www.oracle.com/technetwork/java/javafx/overview/roadmap-1446331.html ). So, for the 1st question the answer is that you have to wait until then. For the 2nd question there is no other way. So, for now go with java swing or start javaFX and wait

In general, when you get an error like this, just do

yum provides ld-linux.so.2

then you'll see something like:

glibc-2.20-5.fc21.i686 : The GNU libc libraries
Repo        : fedora
Matched from:
Provides    : ld-linux.so.2

and then you just run the following like BRPocock wrote (in case you were wondering what the logic was...):

yum install glibc.i686

Stop artisan serve

and try using

php -S localhost:8000 -t public

Enjoy!

Console.WriteLine(String.Join(",", new List<uint> { 1, 2, 3, 4, 5 }));

First Parameter: ","
Second Parameter: new List<uint> { 1, 2, 3, 4, 5 })

String.Join will take a list as a the second parameter and join all of the elements using the string passed as the first parameter into one single string.

If you are using SQLAlchemy's ORM rather than the expression language, you might find yourself wanting to convert an object of type sqlalchemy.orm.query.Query to a Pandas data frame.

The cleanest approach is to get the generated SQL from the query's statement attribute, and then execute it with pandas's read_sql() method. E.g., starting with a Query object called query:

df = pd.read_sql(query.statement, query.session.bind)

Is Button1 visible? I mean, from the server side. Make sure Button1.Visible is true.

Controls that aren't Visible won't be rendered in HTML, so although they are assigned a ClientID, they don't actually exist on the client side.

It's just

$(this).val();

I think jQuery is clever enough to know what you need

/dev/tty is a synonym for the controlling terminal (if any) of the current process. As jtl999 says, it's a character special file; that's what the c in the ls -l output means.

man 4 tty or man -s 4 tty should give you more information, or you can read the man page online here.

Incidentally, pwd > /dev/tty doesn't necessarily print to the shell's stdout (though it is the pwd command's standard output). If the shell's standard output has been redirected to something other than the terminal, /dev/tty still refers to the terminal.

You can also read from /dev/tty, which will normally read from the keyboard.

Python uses duck typing, so it doesn't need special syntax to handle multiple types.

If you're from a C++ background, you'll remember that, as long as the operations used in the template function/class are defined on some type T (at the syntax level), you can use that type T in the template.

So, basically, it works the same way:

1. define a contract for the type of items you want to insert in the binary tree.
2. document this contract (i.e. in the class documentation)
3. implement the binary tree using only operations specified in the contract
4. enjoy

You'll note however, that unless you write explicit type checking (which is usually discouraged), you won't be able to enforce that a binary tree contains only elements of the chosen type.

I recently run into the same problem. I solved it by implementing my own ImageView class.

Here is my Kotlin implementation:

class MyImageView(context: Context): ImageView(context) {
    private var currentDrawableId: Int? = null

    override fun setImageResource(resId: Int) {
        super.setImageResource(resId)
        currentDrawableId = resId
    }

    fun getDrawableId() {
        return currentDrawableId
    }

    fun compareCurrentDrawable(toDrawableId: Int?): Boolean {
        if (toDrawableId == null || currentDrawableId != toDrawableId) {
            return false
        }

        return true
    }

}

If you are searching literally the way to return a JSON list in flask and you are completly sure that your variable is a list then the easy way is (where bin is a list of 1's and 0's):

   return jsonify({'ans':bin}), 201

Finally, in your client you will obtain something like

{ "ans": [ 0.0, 0.0, 1.0, 1.0, 0.0 ] }

You can't selectively escape %, as % always has a special meaning depending on the following character.

In the documentation of Python, at the bottem of the second table in that section, it states:

'%'        No argument is converted, results in a '%' character in the result.

Therefore you should use:

selectiveEscape = "Print percent %% in sentence and not %s" % (test, )

(please note the expicit change to tuple as argument to %)

Without knowing about the above, I would have done:

selectiveEscape = "Print percent %s in sentence and not %s" % ('%', test)

with the knowledge you obviously already had.

For CentOS 7 and MariaDB 10.4, I had success with the following commands:

su -
systemctl set-environment MYSQLD_OPTS="--skip-grant-tables --user=mysql"
systemctl restart mariadb
mysql -u root

flush privileges;
ALTER USER 'root'@'localhost' IDENTIFIED BY 'MyNewPass';
flush privileges;
quit

systemctl unset-environment MYSQLD_OPTS
systemctl restart mariadb

If you have already installed app on your device, try to change bundle identifer on the web .plist (not app plist) with something else like "com.vistair.docunet-test2", after that refresh webpage and try to reinstall... It works for me

If you don't want to wrap a table under any div:

table{
  table-layout: fixed;
}
tbody{
      display: block;
    overflow: auto;
}

There is no way to recursively search through the classpath. You need to know the Full pathname of a resource to be able to retrieve it in this way. The resource may be in a directory in the file system or in a jar file so it is not as simple as performing a directory listing of "the classpath". You will need to provide the full path of the resource e.g. '/com/mypath/bla.xml'.

For your second question, getResource will return the first resource that matches the given resource name. The order that the class path is searched is given in the javadoc for getResource.

Okay, I'd like to just add my class only because there might be some dev out there in the future that wants to connect to a Netbackup server (or something similar) and do stuff from Java while ignoring the SSL cert. This worked for me and we use windows active directory for auth to the Netbackup server.

    SSLContext sslcontext = null;

        Logger.getLogger(main.class.getName()).log(Level.SEVERE, null, ex);
    }
    try {
        sslcontext.init(null, new TrustManager[]{new X509TrustManager() {
            public X509Certificate[] getAcceptedIssuers() {
                return new X509Certificate[0];
            }
            @Override

                .put("domainName", "XX")
                .put("userName", "the username")
                .put("password", "the password").toString();
        System.out.println(jsonString);
        Response response = invocationBuilder.post(Entity.json(jsonString));
        String data = response.readEntity(String.class);
        JSONObject jo = new JSONObject(data);
        the_token = jo.getString("token");
        System.out.println("token is:" + the_token);

    }
    {
        String the_url = "https://the_server:1556/netbackup/admin/jobs/1122012"; //job id 1122012 is an example
        WebTarget webTarget = client.target(the_url);
        Invocation.Builder invocationBuilder = webTarget.request(MediaType.APPLICATION_JSON).header(HttpHeaders.AUTHORIZATION, the_token).header(HttpHeaders.ACCEPT, "application/vnd.netbackup+json;version=1.0");
        Response response = invocationBuilder.get();
        System.out.println("response status:" + response.getStatus());
        String data = response.readEntity(String.class);
        //JSONObject jo = new JSONObject(data);
        System.out.println(data);
    }
}

I know it can be considered off-topic, but I bet the dev that tries to connect to a Netbackup server will probably end up here. By the way many thanks to all the answers in this question! The spec I'm talking about is here and their code samples are (currently) missing a Java example.

***This is of course unsafe since we ignore the cert!

You can add this at the beginning after #include <iostream>:

using namespace std;

Class.getSimpleName()

To expand this question into the realm of use outside of Excel s own VBA, the ActiveWindow property must be addressed as a child of the Excel.Application object.

Example for creating an Excel workbook from Access:

Using the Excel.Application object in another Office application's VBA project will require you to add Microsoft Excel 15.0 Object library (or equivalent for your own version).

Option Explicit

Sub xls_Build__Report()
    Dim xlApp As Excel.Application, ws As Worksheet, wb As Workbook
    Dim fn As String

    Set xlApp = CreateObject("Excel.Application")
    xlApp.DisplayAlerts = False
    xlApp.Visible = True

    Set wb = xlApp.Workbooks.Add
    With wb
        .Sheets(1).Name = "Report"
        With .Sheets("Report")

            'report generation here

        End With

        'This is where the Freeze Pane is dealt with
        'Freezes top row
        With xlApp.ActiveWindow
            .SplitColumn = 0
            .SplitRow = 1
            .FreezePanes = True
        End With

        fn = CurrentProject.Path & "\Reports\Report_" & Format(Date, "yyyymmdd") & ".xlsx"
        If CBool(Len(Dir(fn, vbNormal))) Then Kill fn
        .SaveAs FileName:=fn, FileFormat:=xlOpenXMLWorkbook
    End With

Close_and_Quit:
    wb.Close False
    xlApp.Quit
End Sub

The core process is really just a reiteration of previously submitted answers but I thought it was important to demonstrate how to deal with ActiveWindow when you are not within Excel's own VBA. While the code here is VBA, it should be directly transcribable to other languages and platforms.

object.runtimeType returns the type of object

For example:

print("HELLO".runtimeType); //prints String
var x=0.0;
print(x.runtimeType); //prints double

Try something like this:

df.select([c for c in df.columns if c in ['_2','_4','_5']]).show()

As noted in the release email, linked to from the release tweet and noted in large orange warning that appears on the front page of the documentation, and less orange, but still present, in the readme on the repository and the release on pypi:

xlrd has explicitly removed support for anything other than xls files.

In your case, the solution is to:

• make sure you are on a recent version of Pandas, at least 1.0.1, and preferably the latest release. 1.2 will make his even clearer.
• install openpyxl: https://openpyxl.readthedocs.io/en/stable/
• change your Pandas code to be:

  df1 = pd.read_excel(
       os.path.join(APP_PATH, "Data", "aug_latest.xlsm"),
       engine='openpyxl',
  )
  

For anyone else that may run into this issue, turns out that even if you include #!/usr/bin/env python3 at the beginning of your script, the shebang is ignored if the file isn't executable.

To determine whether or not your file is executable:

• run ./filename.py from the command line
• if you get -bash: ./filename.py: Permission denied, run chmod a+x filename.py
• run ./filename.py again

If you've included import sys; print(sys.version) as Kevin suggested, you'll now see that the script is being interpreted by python3

This is a new security feature of iOS 9. Watch WWDC 2015 Session 703 for more information.

Any app built with SDK 9 needs to provide a LSApplicationQueriesSchemes entry in its plist file, declaring which schemes it attempts to query.

<key>LSApplicationQueriesSchemes</key>
<array>
 <string>urlscheme</string>
 <string>urlscheme2</string>
 <string>urlscheme3</string>
 <string>urlscheme4</string>
</array> 

I tried to use socket.io on AWS, I can at most keep around 600 connections stable.

And I found out it is because socket.io used long polling first and upgraded to websocket later.

after I set the config to use websocket only, I can keep around 9000 connections.

Set this config at client side:

const socket = require('socket.io-client')
const conn = socket(host, { upgrade: false, transports: ['websocket'] })
