Nouns.h doesn't include <string>, but it needs to. You need to add

#include <string>

at the top of that file, otherwise the compiler doesn't know what std::string is when it is encountered for the first time.

One use for the 'Unary Scope Resolution Operator' or 'Colon Colon Operator' is for local and global variable selection of identical names:

    #include <iostream>
    using namespace std;
    
    int variable = 20;
    
    int main()
    {
    float variable = 30;
    
    cout << "This is local to the main function: " << variable << endl;
    cout << "This is global to the main function: " << ::variable << endl;
    
    return 0;
    }

The resulting output would be:

This is local to the main function: 30

This is global to the main function: 20

Other uses could be: Defining a function from outside of a class, to access a static variable within a class or to use multiple inheritance.

I use this approach:

var myNamespace = {}
myNamespace._construct = function()
{
    var staticVariable = "This is available to all functions created here"

    function MyClass()
    {
       // Depending on the class, we may build all the classes here
       this.publicMethod = function()
       {
          //Do stuff
       }
    }

    // Alternatively, we may use a prototype.
    MyClass.prototype.altPublicMethod = function()
    {
        //Do stuff
    }

    function privateStuff()
    {
    }

    function publicStuff()
    {
       // Code that may call other public and private functions
    }

    // List of things to place publically
    this.publicStuff = publicStuff
    this.MyClass = MyClass
}
myNamespace._construct()

// The following may or may not be in another file
myNamespace.subName = {}
myNamespace.subName._construct = function()
{
   // Build namespace
}
myNamespace.subName._construct()

External code can then be:

var myClass = new myNamespace.MyClass();
var myOtherClass = new myNamepace.subName.SomeOtherClass();
myNamespace.subName.publicOtherStuff(someParameter);

If you are using Visual Studio 2010 or plus then check the target framework that is it .Net Framework 4.0 or .Net Framework 4.0 Client Profile. then change is to .Net Framework 4.0.

You need to add reference this .dll file (System.Drawing.dll) to perform drawing operations.

If it is OK then follow these steps to add reference to System.Drawing.dll

1. In Solution Explorer, right-click on the project node and click Add Reference.
2. In the Add Reference dialog box, select the tab indicating the type of component you want to reference.
3. Select the System.Drawing.dll to reference, then click OK.

There is problem in name spacing as in laravel 5.2.3

use DB;
use App\ApiModel; OR  use App\name of model; 

DB::table('tbl_users')->insert($users); 

OR

DB::table('table name')->insert($users);



model 

class ApiModel extends Model
    {

        protected $table='tbl_users';

}

Unnamed namespaces are a utility to make an identifier translation unit local. They behave as if you would choose a unique name per translation unit for a namespace:

namespace unique { /* empty */ }
using namespace unique;
namespace unique { /* namespace body. stuff in here */ }

The extra step using the empty body is important, so you can already refer within the namespace body to identifiers like ::name that are defined in that namespace, since the using directive already took place.

This means you can have free functions called (for example) help that can exist in multiple translation units, and they won't clash at link time. The effect is almost identical to using the static keyword used in C which you can put in in the declaration of identifiers. Unnamed namespaces are a superior alternative, being able to even make a type translation unit local.

namespace { int a1; }
static int a2;

Both a's are translation unit local and won't clash at link time. But the difference is that the a1 in the anonymous namespace gets a unique name.

Read the excellent article at comeau-computing Why is an unnamed namespace used instead of static? (Archive.org mirror).

Generally speaking, I create a namespace for a body of code if I believe there might possibly be function or type name conflicts with other libraries. It also helps to brand code, ala boost:: .

try

from sqlitedbx import SqliteDBzz

I also got this error due to a missing reference. The reason I did not notice is because Resharper offers to add a using and a reference. Adding the using succeeds (but it's highlighted grey), syntax highlighting of missing classes works (sometimes), but adding the reference fails silently.

When manually adding the reference an error pops up, explaining why adding the reference fails (circular reference). Resharper did not pass this error on to the GUI.

I added substr to the test of https://stackoverflow.com/a/25472778/2386943 and that's the fastet way I could test (CentOS PHP 5.3.3, Ubuntu PHP 5.5.9) both with an i5.

As mentioned in the comments by @MrBandersnatch there is even a faster way to do this:

return substr(strrchr(get_class($this), '\\'), 1);

I had the same problem. This worked for me:

• In VB go to Tools » References
• Uncheck the library "Crystal Analysis Common Controls 1.0". Or any library.
• Just leave these 5 references:
  1. Visual Basic For Applications (This is the library that defines the VBA language.)
  2. Microsoft Excel Object Library (This defines all of the elements of Excel.)
  3. OLE Automation (This specifies the types for linking and embedding documents and for automation of other applications and the "plumbing" of the COM system that Excel uses to communicate with the outside world.)
  4. Microsoft Office (This defines things that are common to all Office programs such as Command Bars and Command Bar controls.)
  5. Microsoft Forms 2.0 This is required if you are using a User Form. This library defines things like the user form and the controls that you can place on a form.
• Then Save.

I know its old, but I've found the same issue. My project did build, I then updated Visual Studio to the latest & the project wouldnt build as it couldnt find a type definition from a separate assembly. The other assembly built OK, the main project referenced it correctly & nothing had changed since it built OK.

I cleaned the whole solution & rebuilt it, it failed. I built the assembly on its own, it built OK. The project didnt build. I cleaned & built multiple times, and it failed. I then called a colleague to look at it, when I built with him watching, it all built OK.

I think Visual Studio tooling is the problem, especially as I just updated it.

Unfortunately the tempuri.org URL now just redirects to Bing.

You can see what it used to render via archive.org:

https://web.archive.org/web/20090304024056/http://tempuri.org/

To quote:

Each XML Web Service needs a unique namespace in order for client applications to distinguish it from other services on the Web. By default, ASP.Net Web Services use http://tempuri.org/ for this purpose. While this suitable for XML Web Services under development, published services should use a unique, permanent namespace.

Your XML Web Service should be identified by a namespace that you control. For example, you can use your company's Internet domain name as part of the namespace. Although many namespaces look like URLs, they need not point to actual resources on the Web.

For XML Web Services creating[sic] using ASP.NET, the default namespace can be changed using the WebService attribute's Namespace property. The WebService attribute is applied to the class that contains the XML Web Service methods. Below is a code example that sets the namespace to "http://microsoft.com/webservices/":

C#

[WebService(Namespace="http://microsoft.com/webservices/")]
public class MyWebService {
   // implementation
}

Visual Basic.NET

<WebService(Namespace:="http://microsoft.com/webservices/")> Public Class MyWebService
    ' implementation
End Class

Visual J#.NET

/**@attribute WebService(Namespace="http://microsoft.com/webservices/")*/
public class MyWebService {
    // implementation
}

It's also worth reading section 'A 1.3 Generating URIs' at:

http://www.w3.org/TR/wsdl#_Toc492291092

Try this to get type parameters for generic types:

public static string CSharpName(this Type type)
{
    var sb = new StringBuilder();
    var name = type.Name;
    if (!type.IsGenericType) return name;
    sb.Append(name.Substring(0, name.IndexOf('`')));
    sb.Append("<");
    sb.Append(string.Join(", ", type.GetGenericArguments()
                                    .Select(t => t.CSharpName())));
    sb.Append(">");
    return sb.ToString();
}

Maybe not the best solution (due to the recursion), but it works. Outputs look like:

Dictionary<String, Object>

If you need to order your code into namespaces, just use the keyword namespace:

file1.php

namespace foo\bar;

In file2.php

$obj = new \foo\bar\myObj();

You can also use use. If in file2 you put

use foo\bar as mypath;

you need to use mypath instead of bar anywhere in the file:

$obj  = new mypath\myObj();

Using use foo\bar; is equal to use foo\bar as bar;.

when you bind localhost or 127.0.0.1, it means you can only connect to your service from local.

you cannot bind 10.0.0.1 because it not belong to you, you can only bind ip owned by your computer

you can bind 0.0.0.0 because it means all ip on your computer, so any ip can connect to your service if they can connect to any of your ip

The C++ Standard reads in section 7.3.1.1 Unnamed namespaces, paragraph 2:

The use of the static keyword is deprecated when declaring objects in a namespace scope, the unnamed-namespace provides a superior alternative.

Static only applies to names of objects, functions, and anonymous unions, not to type declarations.

Edit:

The decision to deprecate this use of the static keyword (affecting visibility of a variable declaration in a translation unit) has been reversed (ref). In this case using a static or an unnamed namespace are back to being essentially two ways of doing the exact same thing. For more discussion please see this SO question.

Unnamed namespace's still have the advantage of allowing you to define translation-unit-local types. Please see this SO question for more details.

Credit goes to Mike Percy for bringing this to my attention.

It's compiling because printf isn't type safe, since it uses variable arguments in the C sense¹. printf has no option for std::string, only a C-style string. Using something else in place of what it expects definitely won't give you the results you want. It's actually undefined behaviour, so anything at all could happen.

The easiest way to fix this, since you're using C++, is printing it normally with std::cout, since std::string supports that through operator overloading:

std::cout << "Follow this command: " << myString;

If, for some reason, you need to extract the C-style string, you can use the c_str() method of std::string to get a const char * that is null-terminated. Using your example:

#include <iostream>
#include <string>
#include <stdio.h>

int main()
{
    using namespace std;

    string myString = "Press ENTER to quit program!";
    cout << "Come up and C++ me some time." << endl;
    printf("Follow this command: %s", myString.c_str()); //note the use of c_str
    cin.get();

    return 0;
}

If you want a function that is like printf, but type safe, look into variadic templates (C++11, supported on all major compilers as of MSVC12). You can find an example of one here. There's nothing I know of implemented like that in the standard library, but there might be in Boost, specifically boost::format.

[1]: This means that you can pass any number of arguments, but the function relies on you to tell it the number and types of those arguments. In the case of printf, that means a string with encoded type information like %d meaning int. If you lie about the type or number, the function has no standard way of knowing, although some compilers have the ability to check and give warnings when you lie.

You should really import the module into its own alias.

import datetime as dt
my_datetime = dt.datetime(year, month, day)

The above has the following benefits over the other solutions:

• Calling the variable my_datetime instead of date reduces confusion since there is already a date in the datetime module (datetime.date).
• The module and the class (both called datetime) do not shadow each other.

Please check that your class and namespace name is the same...

It happens when the namespace and class name are the same. do one thing write the full name of the namespace when you want to use the namespace.

using Student.Models.Db;

namespace Student.Controllers
{
    public class HomeController : Controller
    {
        // GET: Home
        public ActionResult Index()
        {
            List<Student> student = null;
            return View();
        }
    }

For a specific Assembly, NameSpace and ClassName:

var assemblyName = "Some.Assembly.Name"
var nameSpace = "Some.Namespace.Name";
var className = "ClassNameFilter";

var asm = Assembly.Load(assemblyName);
var classes = asm.GetTypes().Where(p =>
     p.Namespace == nameSpace &&
     p.Name.Contains(className) 
).ToList();

Note: The project must reference the assembly

As a workaround, you could consider setting environment variables in the outer layer, like this.

main.py:

import os
os.environ['MYVAL'] = str(myintvariable)

mymodule.py:

import os

myval = None
if 'MYVAL' in os.environ:
    myval = os.environ['MYVAL']

As an extra precaution, handle the case when MYVAL is not defined inside the module.

The ScriptIgnoreAttribute class is in the System.Web.Extensions.dll assembly (Located under Assemblies > Framework in the VS Reference Manager). You have to add a reference to that assembly in your class library project.

You can find this information at top of the MSDN page for the ScriptIgnoreAttribute class.

The :: operator is called the scope-resolution operator and does just that, it resolves scope. So, by prefixing a type-name with this, it tells your compiler to look in the global namespace for the type.

Example:

int count = 0;

int main(void) {
  int count = 0;
  ::count = 1;  // set global count to 1
  count = 2;    // set local count to 2
  return 0;
}

You can add PresentationCore.dll more conveniently by editing the project file. Add the following code into your csproj file:

<ItemGroup>
   <FrameworkReference Include="Microsoft.WindowsDesktop.App" />
</ItemGroup>

In your solution explorer, you now should see this framework listed, now. With that, you then can also refer to the classes provided by PresentationCore.dll.

Just telling you about one other possibility: I like using friend definitions for that:

namespace Math
{
    class Matrix
    {
    public:

        [...]

        friend std::ostream& operator<< (std::ostream& stream, const Matrix& matrix) {
            [...]
        }
    };
}

The function will be automatically targeted into the surrounding namespace Math (even though its definition appears within the scope of that class) but will not be visible unless you call operator<< with a Matrix object which will make argument dependent lookup find that operator definition. That can sometimes help with ambiguous calls, since it's invisible for argument types other than Matrix. When writing its definition, you can also refer directly to names defined in Matrix and to Matrix itself, without qualifying the name with some possibly long prefix and providing template parameters like Math::Matrix<TypeA, N>.

If you are creating a code library, then I would use namespace. However, you can still only have one Color enum inside that namespace. If you need an enum that might use a common name, but might have different constants for different classes, use your approach.

I also consider it a bad practice. Why? Just one day I thought that the function of a namespace is to divide stuff, so I shouldn't spoil it with throwing everything into one global bag.

However, if I often use 'cout' and 'cin', I write: using std::cout; using std::cin; in the .cpp file (never in the header file as it propagates with #include). I think that no one sane will ever name a stream cout or cin. ;)

__all__ affects how from foo import * works.

Code that is inside a module body (but not in the body of a function or class) may use an asterisk (*) in a from statement:

from foo import *

The * requests that all attributes of module foo (except those beginning with underscores) be bound as global variables in the importing module. When foo has an attribute __all__, the attribute's value is the list of the names that are bound by this type of from statement.

If foo is a package and its __init__.py defines a list named __all__, it is taken to be the list of submodule names that should be imported when from foo import * is encountered. If __all__ is not defined, the statement from foo import * imports whatever names are defined in the package. This includes any names defined (and submodules explicitly loaded) by __init__.py.

Note that __all__ doesn't have to be a list. As per the documentation on the import statement, if defined, __all__ must be a sequence of strings which are names defined or imported by the module. So you may as well use a tuple to save some memory and CPU cycles. Just don't forget a comma in case the module defines a single public name:

__all__ = ('some_name',)

See also Why is “import *” bad?

Have you changed the namespace of your project? I've seen this happen occasionally where I've changed the namespace in the Project Properties dialog but Visual Studio hasn't changed the namespace declaration in existing code files.

I've seen similar things happen when I was using the .c file extension with C++ code. Other than that, I'd have to agree with everyone about a buggy installation. Does it work if you try to compile the project with an earlier release of VS? Try VC++ Express 2008. Its free on msdn.

When you make a call to using namespace <some_namespace>; all symbols in that namespace will become visible without adding the namespace prefix. A symbol may be for instance a function, class or a variable.

E.g. if you add using namespace std; you can write just cout instead of std::cout when calling the operator cout defined in the namespace std.

This is somewhat dangerous because namespaces are meant to be used to avoid name collisions and by writing using namespace you spare some code, but loose this advantage. A better alternative is to use just specific symbols thus making them visible without the namespace prefix. Eg:

#include <iostream>
using std::cout;

int main() {
  cout << "Hello world!";
  return 0;
}

This thread already has some great answers, but I feel I can bring a little more detail with this additional answer.

First, remember that a namespace declaration with periods, like:

namespace MyCorp.TheProduct.SomeModule.Utilities
{
    ...
}

is entirely equivalent to:

namespace MyCorp
{
    namespace TheProduct
    {
        namespace SomeModule
        {
            namespace Utilities
            {
                ...
            }
        }
    }
}

If you wanted to, you could put using directives on all of these levels. (Of course, we want to have usings in only one place, but it would be legal according to the language.)

The rule for resolving which type is implied, can be loosely stated like this: First search the inner-most "scope" for a match, if nothing is found there go out one level to the next scope and search there, and so on, until a match is found. If at some level more than one match is found, if one of the types are from the current assembly, pick that one and issue a compiler warning. Otherwise, give up (compile-time error).

Now, let's be explicit about what this means in a concrete example with the two major conventions.

(1) With usings outside:

using System;
using System.Collections.Generic;
using System.Linq;
//using MyCorp.TheProduct;  <-- uncommenting this would change nothing
using MyCorp.TheProduct.OtherModule;
using MyCorp.TheProduct.OtherModule.Integration;
using ThirdParty;

namespace MyCorp.TheProduct.SomeModule.Utilities
{
    class C
    {
        Ambiguous a;
    }
}

In the above case, to find out what type Ambiguous is, the search goes in this order:

1. Nested types inside C (including inherited nested types)
2. Types in the current namespace MyCorp.TheProduct.SomeModule.Utilities
3. Types in namespace MyCorp.TheProduct.SomeModule
4. Types in MyCorp.TheProduct
5. Types in MyCorp
6. Types in the null namespace (the global namespace)
7. Types in System, System.Collections.Generic, System.Linq, MyCorp.TheProduct.OtherModule, MyCorp.TheProduct.OtherModule.Integration, and ThirdParty

The other convention:

(2) With usings inside:

namespace MyCorp.TheProduct.SomeModule.Utilities
{
    using System;
    using System.Collections.Generic;
    using System.Linq;
    using MyCorp.TheProduct;                           // MyCorp can be left out; this using is NOT redundant
    using MyCorp.TheProduct.OtherModule;               // MyCorp.TheProduct can be left out
    using MyCorp.TheProduct.OtherModule.Integration;   // MyCorp.TheProduct can be left out
    using ThirdParty;

    class C
    {
        Ambiguous a;
    }
}

Now, search for the type Ambiguous goes in this order:

1. Nested types inside C (including inherited nested types)
2. Types in the current namespace MyCorp.TheProduct.SomeModule.Utilities
3. Types in System, System.Collections.Generic, System.Linq, MyCorp.TheProduct, MyCorp.TheProduct.OtherModule, MyCorp.TheProduct.OtherModule.Integration, and ThirdParty
4. Types in namespace MyCorp.TheProduct.SomeModule
5. Types in MyCorp
6. Types in the null namespace (the global namespace)

(Note that MyCorp.TheProduct was a part of "3." and was therefore not needed between "4." and "5.".)

Concluding remarks

No matter if you put the usings inside or outside the namespace declaration, there's always the possibility that someone later adds a new type with identical name to one of the namespaces which have higher priority.

Also, if a nested namespace has the same name as a type, it can cause problems.

It is always dangerous to move the usings from one location to another because the search hierarchy changes, and another type may be found. Therefore, choose one convention and stick to it, so that you won't have to ever move usings.

Visual Studio's templates, by default, put the usings outside of the namespace (for example if you make VS generate a new class in a new file).

One (tiny) advantage of having usings outside is that you can then utilize the using directives for a global attribute, for example [assembly: ComVisible(false)] instead of [assembly: System.Runtime.InteropServices.ComVisible(false)].

In simple words:

The code you see under if __name__ == "__main__": will only get called upon when your python file is executed as "python example1.py".

However, if you wish to import your python file 'example1.py' as a module to work with another python file say 'example2.py', the code under if __name__ == "__main__": will not run or take any effect.

You can achieve with below queries

1. select extract(xmltype(xml), '//fax/text()').getStringVal() from mytab;

2. select extractvalue(xmltype(xml), '//fax') from mytab;

Amazon provides a policy generator tool:

After that, you can enter the policy requirements for the bucket on the AWS console:

Following is the regex expression to validate the IP-Address.

^((25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\\.){3}(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)$

Are you sure you want to do this? In essence, you're duplicating the data that is in the three original columns. From that point on, you'll need to make sure that the data in the combined field matches the data in the first three columns. This is more overhead for your application, and other processes that update the system will need to understand the relationship.

If you need the data, why not select in when you need it? The SQL for selecting what would be in that field would be:

SELECT CONCAT(zipcode, ' - ', city, ', ', state) FROM Table;

This way, if the data in the fields changes, you don't have to update your combined field.

I guess you'll need absolute position

.vertical_banner {position:relative;}
#bottom_link{position:absolute; bottom:0;}

The ARM architecture was originally designed for Acorn personal computers (See Acorn Archimedes, circa 1987, and RiscPC), which were just as much keyboard-based personal computers as were x86 based IBM PC models. Only later ARM implementations were primarily targeted at the mobile and embedded market segment.

Originally, simple RISC CPUs of roughly equivalent performance could be designed by much smaller engineering teams (see Berkeley RISC) than those working on the x86 development at Intel.

But, nowadays, the fastest ARM chips have very complex multi-issue out-of-order instruction dispatch units designed by large engineering teams, and x86 cores may have something like a RISC core fed by an instruction translation unit.

So, any current differences between the two architectures are more related to the specific market needs of the product niches that the development teams are targeting. (Random opinion: ARM probably makes more in license fees from embedded applications that tend to be far more power and cost constrained. And Intel needs to maintain a performance edge in PCs and servers for their profit margins. Thus you see differing implementation optimizations.)

Its been little late but please take it from me...

In the editor(New Query) by select the database object it can be a table too, if we use the Shortcut Key Alt+F1 we will get all the information of the object and I think will solve your problem as well.

In C/C++ sizeof. always gives the number of bytes in the entire object, and arrays are treated as one object. Note: sizeof a pointer--to the first element of an array or to a single object--gives the size of the pointer, not the object(s) pointed to. Either way, sizeof does not give the number of elements in the array (its length). To get the length, you need to divide by the size of each element. eg.,

for( unsigned int a = 0; a < sizeof(texts)/sizeof(texts[0]); a = a + 1 )

As for doing it the C++11 way, the best way to do it is probably

for(const string &text : texts)
    cout << "value of text: " << text << endl;

This lets the compiler figure out how many iterations you need.

EDIT: as others have pointed out, std::array is preferred in C++11 over raw arrays; however, none of the other answers addressed why sizeof is failing the way it is, so I still think this is the better answer.

Take a look at this... http://getbootstrap.com/

For big websites I use Bootstrap and sometimes (for simple websites) I create all the style with some @mediaqueries. It's very simple, just think all the code in percentage.

.container {
max-width: 1200px;
width: 100%;
margin: 0 auto;
}

Inside the container, your structure must have widths in percentage like this...

.col-1 {
width: 40%;
float: left;
}

.col-2 {
width: 60%;
float: left;
}

@media screen and (max-width: 320px) {
.col-1, .col-2 { width: 100%; }
}

In some simple interfaces, if you start to develop the project in this way, you will have great chances to have a fully responsive site using break points only to adjust the flow of objects.

Structure in C

First you need to declare your structure:

struct mystruct{
 char element_1,
 char element_2
};

Instantiate C structure

Once you declared your structure , you can instantiate a variable that has as type your structure using either:

mystruct struct_example;

or :

mystruct* struct_example;

For the first use case you can access the varaiable eleemnet using the following syntax: struct_example.element_1 = 5;

For the second use case which is having a pointer to variable of type your structure, to be able to access the variable structure you need an arrow:

struct_example->element_1 = 5;

Try

var e = document.getElementById("mySelect");
var selectedOp = e.options[e.selectedIndex].text;

The two that come to mind are:

• pyPdf2
• PDFMiner

This because in.nextInt() only receive a int number, doesn't receive a new line. So you input 3 and press "Enter", the end of line is read by in.nextline().

Here is my code:

int nnames;
String names[];

System.out.print("How many names are you going to save: ");
Scanner in = new Scanner(System.in);
nnames = in.nextInt();
in.nextLine();
names = new String[nnames];

for (int i = 0; i < names.length; i++){
        System.out.print("Type a name: ");
        names[i] = in.nextLine();
}

You can add the TextField as a child to a Container that has a BoxDecoration with border property:

new Container(
  margin: const EdgeInsets.all(15.0),
  padding: const EdgeInsets.all(3.0),
  decoration: BoxDecoration(
    border: Border.all(color: Colors.blueAccent)
  ),
  child: Text("My Awesome Border"),
)

I would recommend using the coding standards from IDesign or the ones listed on Brad Abram's website. Those are the best two that I have found.

Brad would say...

Classes member should be alphabetized, and grouped into sections (Fields, Constructors, Properties, Events, Methods, Private interface implementations, Nested types)

Update for Retrofit 2.0.0-beta3

Now you have to use okhttp3 with builder. Also the old interceptor will not work. This response is tailored for Android.

Here's a quick copy paste for you with the new stuff.

1. Modify your gradle file to

  compile 'com.squareup.retrofit2:retrofit:2.0.0-beta3'
  compile "com.squareup.retrofit2:converter-gson:2.0.0-beta3"
  compile "com.squareup.retrofit2:adapter-rxjava:2.0.0-beta3"
  compile 'com.squareup.okhttp3:logging-interceptor:3.0.1'

2. Check this sample code:

with the new imports. You can remove Rx if you don't use it, also remove what you don't use.

import okhttp3.OkHttpClient;
import okhttp3.logging.HttpLoggingInterceptor;
import retrofit2.GsonConverterFactory;
import retrofit2.Retrofit;
import retrofit2.RxJavaCallAdapterFactory;
import retrofit2.http.GET;
import retrofit2.http.Query;
import rx.Observable;

public interface APIService {

  String ENDPOINT = "http://api.openweathermap.org";
  String API_KEY = "2de143494c0b2xxxx0e0";

  @GET("/data/2.5/weather?appid=" + API_KEY) Observable<WeatherPojo> getWeatherForLatLon(@Query("lat") double lat, @Query("lng") double lng, @Query("units") String units);


  class Factory {

    public static APIService create(Context context) {

      OkHttpClient.Builder builder = new OkHttpClient().newBuilder();
      builder.readTimeout(10, TimeUnit.SECONDS);
      builder.connectTimeout(5, TimeUnit.SECONDS);

      if (BuildConfig.DEBUG) {
        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BASIC);
        builder.addInterceptor(interceptor);
      }

      //Extra Headers

      //builder.addNetworkInterceptor().add(chain -> {
      //  Request request = chain.request().newBuilder().addHeader("Authorization", authToken).build();
      //  return chain.proceed(request);
      //});

      builder.addInterceptor(new UnauthorisedInterceptor(context));
      OkHttpClient client = builder.build();

      Retrofit retrofit =
          new Retrofit.Builder().baseUrl(APIService.ENDPOINT).client(client).addConverterFactory(GsonConverterFactory.create()).addCallAdapterFactory(RxJavaCallAdapterFactory.create()).build();

      return retrofit.create(APIService.class);
    }
  }
}

Bonus

I know it's offtopic but I find it cool.

In case there's an http error code of unauthorized, here is an interceptor. I use eventbus for transmitting the event.

import android.content.Context;
import android.os.Handler;
import android.os.Looper;
import com.androidadvance.ultimateandroidtemplaterx.BaseApplication;
import com.androidadvance.ultimateandroidtemplaterx.events.AuthenticationErrorEvent;

import de.greenrobot.event.EventBus;
import java.io.IOException;
import javax.inject.Inject;
import okhttp3.Interceptor;
import okhttp3.Response;

public class UnauthorisedInterceptor implements Interceptor {

  @Inject EventBus eventBus;

  public UnauthorisedInterceptor(Context context) {
    BaseApplication.get(context).getApplicationComponent().inject(this);
  }

  @Override public Response intercept(Chain chain) throws IOException {
    Response response = chain.proceed(chain.request());
    if (response.code() == 401) {
      new Handler(Looper.getMainLooper()).post(() -> eventBus.post(new AuthenticationErrorEvent()));
    }
    return response;
  }
}

code take from https://github.com/AndreiD/UltimateAndroidTemplateRx (my project).

Well, your syntax isn't really Python to begin with.

Iterations in Python are over he contents of containers (well, technically it's over iterators), with a syntax for item in container. In this case, the container is the cars list, but you want to skip the first and last elements, so that means cars[1:-1] (python lists are zero-based, negative numbers count from the end, and : is slicing syntax.

So you want

for c in cars[1:-1]:
    do something with c

          <table id="myData">

          </table>

           <script type="text/javascript">
              $('#search').click(function() {
                    alert("submit handler has fired");
                    $.ajax({
                        type: 'POST',
                        url: 'cityResults.htm',
                        data: $('#cityDetails').serialize(),

                        success: function(data){ 
                            $.each(data, function( index, value ) {
                               var row = $("<tr><td>" + value.city + "</td><td>" + value.cStatus + "</td></tr>");
                               $("#myData").append(row);
                            });
                        },
                        error: function(jqXHR, textStatus, errorThrown){
                            alert('error: ' + textStatus + ': ' + errorThrown);
                        }
                    });
                    return false;//suppress natural form submission
                }); 

   </script>

loop through the data and append it to a table like the code above.

$utfEncodedArray = array_map("utf8_encode", $inputArray );

Does the job and returns a serialized array with numeric keys (not an assoc).

I know this is a bit old, but in case another beginner is going through this, I'll share some code that covers a bit more of the basic operations, here is another example that also includes the option to cancel the process and also report to the user the status of the process. I'm going to add on top of the code given by Alex Aza in the solution above

public Form1()
{
    InitializeComponent();

    backgroundWorker1.DoWork += backgroundWorker1_DoWork;
    backgroundWorker1.ProgressChanged += backgroundWorker1_ProgressChanged;
    backgroundWorker1.RunWorkerCompleted += backgroundWorker1_RunWorkerCompleted;  //Tell the user how the process went
    backgroundWorker1.WorkerReportsProgress = true;
    backgroundWorker1.WorkerSupportsCancellation = true; //Allow for the process to be cancelled
}

//Start Process
private void button1_Click(object sender, EventArgs e)
{
    backgroundWorker1.RunWorkerAsync();
}

//Cancel Process
private void button2_Click(object sender, EventArgs e)
{
    //Check if background worker is doing anything and send a cancellation if it is
    if (backgroundWorker1.IsBusy)
    {
        backgroundWorker1.CancelAsync();
    }

}

private void backgroundWorker1_DoWork(object sender, System.ComponentModel.DoWorkEventArgs e)
{
    for (int i = 0; i < 100; i++)
    {
        Thread.Sleep(1000);
        backgroundWorker1.ReportProgress(i);

        //Check if there is a request to cancel the process
        if (backgroundWorker1.CancellationPending)
        {
            e.Cancel = true;
            backgroundWorker1.ReportProgress(0);
            return;
        }
    }
    //If the process exits the loop, ensure that progress is set to 100%
    //Remember in the loop we set i < 100 so in theory the process will complete at 99%
    backgroundWorker1.ReportProgress(100);
}

private void backgroundWorker1_ProgressChanged(object sender, System.ComponentModel.ProgressChangedEventArgs e)
{
    progressBar1.Value = e.ProgressPercentage;
}

private void backgroundWorker1_RunWorkerCompleted(object sender, System.ComponentModel.RunWorkerCompletedEventArgs e)
{
    if (e.Cancelled)
    {
         lblStatus.Text = "Process was cancelled";
    }
    else if (e.Error != null)
    {
         lblStatus.Text = "There was an error running the process. The thread aborted";
    }
    else
    {
       lblStatus.Text = "Process was completed";
    }
}

Create a list of lists:

with open("/path/to/file") as file:
    lines = []
    for line in file:
        # The rstrip method gets rid of the "\n" at the end of each line
        lines.append(line.rstrip().split(","))

Nobody seems to address the case of summing elements of a vector that can have NaN values in it, e.g. numerical_limits<double>::quite_NaN()

I usually loop through the elements and bluntly check.

vector<double> x;

//...

size_t n = x.size();

double sum = 0;

for (size_t i = 0; i < n; i++){

  sum += (x[i] == x[i] ? x[i] : 0);

}

It's not fancy at all, i.e. no iterators or any other tricks but I this is how I do it. Some times if there are other things to do inside the loop and I want the code to be more readable I write

double val = x[i];

sum += (val == val ? val : 0);

//...

inside the loop and re-use val if needed.

Do it like this:

Parentdivimage should have specified width and height, and its position should be:

position: relative;

Just inside the parentdivimage, next to other divs that parent contains you should put:

<a href="linkt.to.smthn.com"><span class="clickable"></span></a>

Then in css file:

.clickable {
  height: 100%;
  width: 100%;
  left: 0;
  top: 0;
  position: absolute;     
  z-index: 1;
}

The span tag will fill out its parent block which is parentdiv, because of height and width set to 100%. Span will be on the top of all of surrounding elements because of setting z-index higher than other elements. Finally span will be clickable, because it's inside of an 'a' tag.

From the Ansible documentation:

Delegation This isn’t actually rolling update specific but comes up frequently in those cases.

If you want to perform a task on one host with reference to other hosts, use the ‘delegate_to’ keyword on a task. This is ideal for placing nodes in a load balanced pool, or removing them. It is also very useful for controlling outage windows. Be aware that it does not make sense to delegate all tasks, debug, add_host, include, etc always get executed on the controller. Using this with the ‘serial’ keyword to control the number of hosts executing at one time is also a good idea:

---

- hosts: webservers
  serial: 5

  tasks:

  - name: take out of load balancer pool
    command: /usr/bin/take_out_of_pool {{ inventory_hostname }}
    delegate_to: 127.0.0.1

  - name: actual steps would go here
    yum:
      name: acme-web-stack
      state: latest

  - name: add back to load balancer pool
    command: /usr/bin/add_back_to_pool {{ inventory_hostname }}
    delegate_to: 127.0.0.1

These commands will run on 127.0.0.1, which is the machine running Ansible. There is also a shorthand syntax that you can use on a per-task basis: ‘local_action’. Here is the same playbook as above, but using the shorthand syntax for delegating to 127.0.0.1:

---

# ...

  tasks:

  - name: take out of load balancer pool
    local_action: command /usr/bin/take_out_of_pool {{ inventory_hostname }}

# ...

  - name: add back to load balancer pool
    local_action: command /usr/bin/add_back_to_pool {{ inventory_hostname }}

A common pattern is to use a local action to call ‘rsync’ to recursively copy files to the managed servers. Here is an example:

---
# ...
  tasks:

  - name: recursively copy files from management server to target
    local_action: command rsync -a /path/to/files {{ inventory_hostname }}:/path/to/target/

Note that you must have passphrase-less SSH keys or an ssh-agent configured for this to work, otherwise rsync will need to ask for a passphrase.

Create a variant array (easiest by reading equivalent range in to a variant variable).

Then fill the array, and assign the array directly to the range.

Dim myArray As Variant

myArray = Range("blahblah")

Range("bingbing") = myArray

The variant array will end up as a 2-D matrix.

The time zone is a session parameter. So, you can change the timezone for the current session.

See the doc.

set timezone TO 'GMT';

Or, more closely following the SQL standard, use the SET TIME ZONE command. Notice two words for "TIME ZONE" where the code above uses a single word "timezone".

SET TIME ZONE 'UTC';

The doc explains the difference:

SET TIME ZONE extends syntax defined in the SQL standard. The standard allows only numeric time zone offsets while PostgreSQL allows more flexible time-zone specifications. All other SET features are PostgreSQL extensions.

ssh-keygen -f private.pem -y > public.pub

You will need to link to the file relative to the file that includes eventManager.php (Page A)

Change your code from
require_once('../includes/dbconn.inc');

To
require_once('../mysite/php/includes/dbconn.inc');

Ugly but works:

>>> s
'aaa12333bb445bb54b5b52'
>>> a = ''.join(filter(lambda x : x.isdigit(), s))
>>> a
'1233344554552'
>>>

dep is the official experiment for dependency management for Go language. It requires Go 1.8 or newer to compile.

To start managing dependencies using dep, run the following command from your project's root directory:

dep init

After execution two files will be generated: Gopkg.toml ("manifest"), Gopkg.lock and necessary packages will be downloaded into vendor directory.

Let's assume that you have the project which uses github.com/gorilla/websocket package. dep will generate following files:

Gopkg.toml

# Gopkg.toml example
#
# Refer to https://github.com/golang/dep/blob/master/docs/Gopkg.toml.md
# for detailed Gopkg.toml documentation.
#
# required = ["github.com/user/thing/cmd/thing"]
# ignored = ["github.com/user/project/pkgX", "bitbucket.org/user/project/pkgA/pkgY"]
#
# [[constraint]]
#   name = "github.com/user/project"
#   version = "1.0.0"
#
# [[constraint]]
#   name = "github.com/user/project2"
#   branch = "dev"
#   source = "github.com/myfork/project2"
#
# [[override]]
#  name = "github.com/x/y"
#  version = "2.4.0"


[[constraint]]
  name = "github.com/gorilla/websocket"
  version = "1.2.0"

Gopkg.lock

# This file is autogenerated, do not edit; changes may be undone by the next 'dep ensure'.


[[projects]]
  name = "github.com/gorilla/websocket"
  packages = ["."]
  revision = "ea4d1f681babbce9545c9c5f3d5194a789c89f5b"
  version = "v1.2.0"

[solve-meta]
  analyzer-name = "dep"
  analyzer-version = 1
  inputs-digest = "941e8dbe52e16e8a7dff4068b7ba53ae69a5748b29fbf2bcb5df3a063ac52261"
  solver-name = "gps-cdcl"
  solver-version = 1

There are commands which help you to update/delete/etc packages, please find more info on official github repo of dep (dependency management tool for Go).

var a = moment([2007, 0, 29]);

I guess this is a fairly old question, but now in 2017. We have neovim, which is a fork of vim which adds terminal support.

So invoking :term would open a terminal window. The beauty of this solution as opposed to using tmux (a terminal multiplexer) is that you'll have the same window bindings as your vim setup. neovim is compatible with vim, so you can basically copy and paste your .vimrc and it will just work.

More advantages are you can switch to normal mode on the opened terminal and you can do basic copy and editing. It is also pretty useful for git commits too I guess, since everything in your buffer you can use in auto-complete.

I'll update this answer since vim is also planning to release terminal support, probably in vim 8.1. You can follow the progress here: https://groups.google.com/forum/#!topic/vim_dev/Q9gUWGCeTXM

Once it's released, I do believe this is a more superior setup than using tmux.

To get list of all keys

using System.Linq;
List<String> myKeys = myDict.Keys.ToList();

System.Linq is supported in .Net framework 3.5 or above. See the below links if you face any issue in using System.Linq

Visual Studio Does not recognize System.Linq

System.Linq Namespace

You can create a DAO method to do this.

@Dao 
interface MyDao {
    @Query("DELETE FROM myTableName")
    public void nukeTable();
}

If a method doesn't return anything, it's either one of the following

• imperative - You're either asking the object to do something to itself.. e.g change state (without expecting any confirmation.. its assumed that it will be done)
• informational - just notifying someone that something happened (without expecting action or response) respectively.

Imperative methods - you can verify if the task was actually performed. Verify if state change actually took place. e.g.

void DeductFromBalance( dAmount ) 

can be tested by verifying if the balance post this message is indeed less than the initial value by dAmount

Informational methods - are rare as a member of the public interface of the object... hence not normally unit-tested. However if you must, You can verify if the handling to be done on a notification takes place. e.g.

void OnAccountDebit( dAmount )  // emails account holder with info

can be tested by verifying if the email is being sent

Post more details about your actual method and people will be able to answer better.
Update: Your method is doing 2 things. I'd actually split it into two methods that can now be independently tested.

string[] ExamineLogFileForX( string sFileName );
void InsertStringsIntoDatabase( string[] );

String[] can be easily verified by providing the first method with a dummy file and expected strings. The second one is slightly tricky.. you can either use a Mock (google or search stackoverflow on mocking frameworks) to mimic the DB or hit the actual DB and verify if the strings were inserted in the right location. Check this thread for some good books... I'd recomment Pragmatic Unit Testing if you're in a crunch.
In the code it would be used like

InsertStringsIntoDatabase( ExamineLogFileForX( "c:\OMG.log" ) );

You can simply make the top div fixed:

#top { position: fixed; top: 20px; left: 20px; }

with git 1.7, there's a really easy way using git rebase:

stage your files:

git add $files

create a new commit and re-use commit message of your "broken" commit

git commit -c master~4

prepend fixup! in the subject line (or squash! if you want to edit commit (message)):

fixup! Factored out some common XPath Operations

use git rebase -i --autosquash to fixup your commit

Leaving an incredibly simple example in case it helps.

When variable doesn't exist:

if defined? a then "hi" end
# => nil

When variable does exist:

a = 2
if defined? a then "hi" end
# => "hi"

If you want to stick to command line FTP, you should try NcFTP. Then you can use get -R to recursively get a folder. You will also get completion.

There is no block comment on shell script.

Using vi (yes, vi) you can easily comment from line n to m

<ESC>
:10,100s/^/#/

(that reads, from line 10 to 100 substitute line start (^) with a # sign.)

and un comment with

<ESC>
:10,100s/^#//

(that reads, from line 10 to 100 substitute line start (^) followed by # with noting //.)

vi is almost universal anywhere where there is /bin/sh.

I cannot see why there is a recommendation to use scanf() here. scanf() is safe only if you add restriction parameters to the format string - such as %64s or so.

A much better way is to use char * fgets ( char * str, int num, FILE * stream );.

int main()
{
    char data[64];
    if (fgets(data, sizeof data, stdin)) {
        // input has worked, do something with data
    }
}

(untested)

Your problem is that, if the user clicks cancel, operationType is null and thus throws a NullPointerException. I would suggest that you move

if (operationType.equalsIgnoreCase("Q")) 

to the beginning of the group of if statements, and then change it to

if(operationType==null||operationType.equalsIgnoreCase("Q")). 

This will make the program exit just as if the user had selected the quit option when the cancel button is pushed.

Then, change all the rest of the ifs to else ifs. This way, once the program sees whether or not the input is null, it doesn't try to call anything else on operationType. This has the added benefit of making it more efficient - once the program sees that the input is one of the options, it won't bother checking it against the rest of them.

This only works in situations where you have a numeric field, but you can put a minus sign in front of the field name like so:

reportingNameGroups = reportingNameGroups.OrderBy(x=> - x.GroupNodeId);

However this works a little bit different than OrderByDescending when you have are running it on an int? or double? or decimal? fields.

What will happen is on OrderByDescending the nulls will be at the end, vs with this method the nulls will be at the beginning. Which is useful if you want to shuffle nulls around without splitting data into pieces and splicing it later.

df = pd.read_csv('somefile.csv', low_memory=False)

This should solve the issue. I got exactly the same error, when reading 1.8M rows from a CSV.

Random random = new Random();
int n = random.nextInt(69) + 32;
if (n > 96) {
    n += 26;
}
char c = (char) n;

I guess it depends which punctuation you want to include, but this should generate a random character including all of the punctuation on this ASCII table. Basically, I've generated a random int from 32 - 96 or 123 - 126, which I have then casted to a char, which gives the ASCII equivalent of that number. Also, make sure youimport java.util.Random

I use this and it works great for me for setting any color I want.

public static final int MY_COLOR = Color.rgb(255, 102, 153);

Set the colors using 0-255 for each red, green and blue then anywhere you want that color used just put MY_COLOR instead of Color.BLUE or Color.RED or any of the other static colors the Color class offers.

Just do a Google search for color chart and it you can find a chart with the correct RGB codes using 0-255.

I do like below to :

var book: MutableList<Books> = mutableListOf()

/** Returns a new [MutableList] with the given elements. */

public fun <T> mutableListOf(vararg elements: T): MutableList<T>
    = if (elements.size == 0) ArrayList() else ArrayList(ArrayAsCollection(elements, isVarargs = true))

I had the same problem and my solution was:

Go to "Turn Windows features on or off" > Internet Information Services > World Wide Web Services > Application Development Features >Enable ASP.NET 4.5

This is what I got from oracle documentation, but it is for oracle 10g release 2:

When you define a NUMBER variable, you can specify its precision (p) and scale (s) so that it is sufficiently, but not unnecessarily, large. Precision is the number of significant digits. Scale can be positive or negative. Positive scale identifies the number of digits to the right of the decimal point; negative scale identifies the number of digits to the left of the decimal point that can be rounded up or down.

The NUMBER data type is supported by Oracle Database standard libraries and operates the same way as it does in SQL. It is used for dimensions and surrogates when a text or INTEGER data type is not appropriate. It is typically assigned to variables that are not used for calculations (like forecasts and aggregations), and it is used for variables that must match the rounding behavior of the database or require a high degree of precision. When deciding whether to assign the NUMBER data type to a variable, keep the following facts in mind in order to maximize performance:

• Analytic workspace calculations on NUMBER variables is slower than other numerical data types because NUMBER values are calculated in software (for accuracy) rather than in hardware (for speed).
• When data is fetched from an analytic workspace to a relational column that has the NUMBER data type, performance is best when the data already has the NUMBER data type in the analytic workspace because a conversion step is not required.

the solution here worked for me : https://community.hortonworks.com/articles/4427/fix-under-replicated-blocks-in-hdfs-manually.html

su - <$hdfs_user>

bash-4.1$ hdfs fsck / | grep 'Under replicated' | awk -F':' '{print $1}' >> /tmp/under_replicated_files 

-bash-4.1$ for hdfsfile in `cat /tmp/under_replicated_files`; do echo "Fixing $hdfsfile :" ;  hadoop fs -setrep 3 $hdfsfile; done

Python lacks the tail recursion optimizations common in functional languages like lisp. In Python, recursion is limited to 999 calls (see sys.getrecursionlimit).

If 999 depth is more than you are expecting, check if the implementation lacks a condition that stops recursion, or if this test may be wrong for some cases.

I dare to say that in Python, pure recursive algorithm implementations are not correct/safe. A fib() implementation limited to 999 is not really correct. It is always possible to convert recursive into iterative, and doing so is trivial.

It is not reached often because in many recursive algorithms the depth tend to be logarithmic. If it is not the case with your algorithm and you expect recursion deeper than 999 calls you have two options:

1) You can change the recursion limit with sys.setrecursionlimit(n) until the maximum allowed for your platform:

sys.setrecursionlimit(limit):

Set the maximum depth of the Python interpreter stack to limit. This limit prevents infinite recursion from causing an overflow of the C stack and crashing Python.

The highest possible limit is platform-dependent. A user may need to set the limit higher when she has a program that requires deep recursion and a platform that supports a higher limit. This should be done with care, because a too-high limit can lead to a crash.

2) You can try to convert the algorithm from recursive to iterative. If recursion depth is bigger than allowed by your platform, it is the only way to fix the problem. There are step by step instructions on the Internet and it should be a straightforward operation for someone with some CS education. If you are having trouble with that, post a new question so we can help.

Each commit is associated with two dates, the committer date and the author date. You can view these dates with:

git log --format=fuller

If you want to change the author date and the committer date of the last 6 commits, you can simply use an interactive rebase :

git rebase -i HEAD~6

.

pick c95a4b7 Modification 1
pick 1bc0b44 Modification 2
pick de19ad3 Modification 3
pick c110e7e Modification 4
pick 342256c Modification 5
pick 5108205 Modification 6

# Rebase eadedca..5108205 onto eadedca (6 commands)
#
# Commands:
# p, pick = use commit
# r, reword = use commit, but edit the commit message
# e, edit = use commit, but stop for amending
# s, squash = use commit, but meld into previous commit
# f, fixup = like "squash", but discard this commit's log message
# x, exec = run command (the rest of the line) using shell
# d, drop = remove commit

For all commits where you want to change the date, replace pick by edit (or just e), then save and quit your editor.

You can now amend each commit by specifying the author date and the committer date in ISO-8601 format:

GIT_COMMITTER_DATE="2017-10-08T09:51:07" git commit --amend --date="2017-10-08T09:51:07"

The first date is the commit date, the second one is the author date.

Then go to the next commit with :

git rebase --continue

Repeat the process until you amend all your commits. Check your progression with git status.

var someParam = xxxxxxx;

commentbtn.click(function(){

    alert(someParam );
});

Like what Volker mentioned, nested structs is the way to go. But if you really do not want nested structs, you can override the UnmarshalJSON func.

https://play.golang.org/p/dqn5UdqFfJt

type A struct {
    FooBar string // takes foo.bar
    FooBaz string // takes foo.baz
    More   string 
}

func (a *A) UnmarshalJSON(b []byte) error {

    var f interface{}
    json.Unmarshal(b, &f)

    m := f.(map[string]interface{})

    foomap := m["foo"]
    v := foomap.(map[string]interface{})

    a.FooBar = v["bar"].(string)
    a.FooBaz = v["baz"].(string)
    a.More = m["more"].(string)

    return nil
}

Please ignore the fact that I'm not returning a proper error. I left that out for simplicity.

UPDATE: Correctly retrieving "more" value.

If it is cached on the server, there is nothing you can do in the browser to fix this. You have to wait for the server to reload the file. You can't even delete the file and re-upload it. This could take even longer if you are using a caching server like Cloudflare (it will even survive a server reboot). You could rename it and load a copy.

  $("#target").on({
        hover: function(){
           //do on mouse hover
        },  
        click: function(){
            //do on mouse click
        }  
    });

Just to be clear, all the answers so far are correct, but the reasoning behind them is not explained very well.

The sumall variable is not yet a string. Parentheticals will not convert to a string (e.g. summ = (int(birthday[0])+int(birthday[1])) still returns an integer. It looks like you most likely intended to type str((int(sumall[0])+int(sumall[1]))), but forgot to. The reason the str() function fixes everything is because it converts anything in it compatible to a string.

If you want to check the display value, https://stackoverflow.com/a/1189281/5622596 already posted the answer.

However if instead of checking whether an element has a style of style="display:none" you want to know if that element is visible. Then use .is(":visible")

For example: $('#idDetails').is(":visible");

This will be true if it is visible & false if it is not.

Update your get_categories() method to return the total (wrapped in an observable):

// Note that .subscribe() is gone and I've added a return.
get_categories(number) {
  return this.http.post( url, body, {headers: headers, withCredentials:true})
    .map(response => response.json());
}

In search_categories(), you can subscribe the observable returned by get_categories() (or you could keep transforming it by chaining more RxJS operators):

// send_categories() is now called after get_categories().
search_categories() {
  this.get_categories(1)
    // The .subscribe() method accepts 3 callbacks
    .subscribe(
      // The 1st callback handles the data emitted by the observable.
      // In your case, it's the JSON data extracted from the response.
      // That's where you'll find your total property.
      (jsonData) => {
        this.send_categories(jsonData.total);
      },
      // The 2nd callback handles errors.
      (err) => console.error(err),
      // The 3rd callback handles the "complete" event.
      () => console.log("observable complete")
    );
}

Note that you only subscribe ONCE, at the end.

Like I said in the comments, the .subscribe() method of any observable accepts 3 callbacks like this:

obs.subscribe(
  nextCallback,
  errorCallback,
  completeCallback
);

They must be passed in this order. You don't have to pass all three. Many times only the nextCallback is implemented:

obs.subscribe(nextCallback);

suppose you're posting a html form with this:

<input type="text" name="username">

If using raw cgi:

import cgi
form = cgi.FieldStorage()
print form["username"]

If using Django, Pylons, Flask or Pyramid:

print request.GET['username'] # for GET form method
print request.POST['username'] # for POST form method

Using Turbogears, Cherrypy:

from cherrypy import request
print request.params['username']

Web.py:

form = web.input()
print form.username

Werkzeug:

print request.form['username']

If using Cherrypy or Turbogears, you can also define your handler function taking a parameter directly:

def index(self, username):
    print username

Google App Engine:

class SomeHandler(webapp2.RequestHandler):
    def post(self):
        name = self.request.get('username') # this will get the value from the field named username
        self.response.write(name) # this will write on the document

So you really will have to choose one of those frameworks.

Just To mention, in CSS 3

:after

should be used like this

::after

From https://developer.mozilla.org/de/docs/Web/CSS/::after :

The ::after notation was introduced in CSS 3 in order to establish a discrimination between pseudo-classes and pseudo-elements. Browsers also accept the notation :after introduced in CSS 2.

So it should be:

li { display: inline; list-style-type: none; }
li::after { content: ", "; }
li:last-child::before { content: "and "; }
li:last-child::after { content: "."; }

SQL Server 2012 has a wonderful and long-awaited new DATEFROMPARTS function (which will raise an error if the date is invalid - my main objection to a DATEADD-based solution to this problem):

http://msdn.microsoft.com/en-us/library/hh213228.aspx

DATEFROMPARTS(ycolumn, mcolumn, dcolumn)

or

DATEFROMPARTS(@y, @m, @d)

getFragmentManager().addOnBackStackChangedListener(new FragmentManager.OnBackStackChangedListener() {
        @Override
        public void onBackStackChanged() {
            List<Fragment> fragments = getFragmentManager().getFragments();
            if (fragments.size() > 0 && fragments.get(fragments.size() - 1) instanceof YoureFragment){
                //todo if fragment visible
            } else {
                //todo if fragment invisible
            }

        }
    });

but be careful if more than one fragment visible

Consider this code:

Products::whereIn('id', function($query){
    $query->select('paper_type_id')
    ->from(with(new ProductCategory)->getTable())
    ->whereIn('category_id', ['223', '15'])
    ->where('active', 1);
})->get();

You can only use - on the numeric entries, so you can use decreasing and negate the ones you want in increasing order:

DT[order(x,-v,decreasing=TRUE),]
      x y v
 [1,] c 1 7
 [2,] c 3 8
 [3,] c 6 9
 [4,] b 1 1
 [5,] b 3 2
 [6,] b 6 3
 [7,] a 1 4
 [8,] a 3 5
 [9,] a 6 6

There's actually no need for visibility or opacity - you can simply use color, which has the upside of keeping any "blinking" to the text only:

blink {_x000D_
    display: inline;_x000D_
    color: inherit;_x000D_
    animation: blink 1s steps(1) infinite;_x000D_
    -webkit-animation: blink 1s steps(1) infinite;_x000D_
}_x000D_
@keyframes blink { 50% { color: transparent; } }_x000D_
@-webkit-keyframes blink { 50% { color: transparent; } }

Here is some text, <blink>this text will blink</blink>, this will not.

For the Swift-inclined:

if let registration: AnyObject = NSClassFromString("UIUserNotificationSettings") { // iOS 8+
    let notificationTypes: UIUserNotificationType = (.Alert | .Badge | .Sound)
    let notificationSettings: UIUserNotificationSettings = UIUserNotificationSettings(forTypes: notificationTypes, categories: nil)

    application.registerUserNotificationSettings(notificationSettings)
} else { // iOS 7
    application.registerForRemoteNotificationTypes(.Alert | .Badge | .Sound)
}

$.getJSON(my_url, function(json) {
  my_json = json;

None of these https://stackoverflow.com/a/7597360/808128 do work for me. Even "adding assembly referecene to system.web/compilation/assemblies section of the root web.config file". So the two ways remains for me: 1) to add a public wrap class for my assembly that Razor code can access to this assembly through this wrap; 2) just add assembly logic to a public class in the same assembly where the Razor's code is located.

Luckily, I do not have to do that too often :)

Just ask it for the objectForKey:@"b". If it returns nil, no object is set at that key.

if ([xyz objectForKey:@"b"]) {

This worked for me vb2019. I copied my source project folder. I then pasted the project, and renamed the the folder to whatever. In order to break the ties back to the source project folder, I temporarily renamed the source folder. I opened my destination project. The paths to the forms and modules were re-discovered in the local folder. I went through all my forms and modules to make sure they were working. I ran the project. I closed the project. I renamed the source project folder back to is't original name. I can open both projects at the same time without errors.

I couldn't get David Chu's answer to work for a RecyclerView item and figured out I needed to constrain the ImageView to the parent. Set the ImageView width to 0dp and constrain its start and end to the parent. I'm not sure if setting the width to wrap_content or match_parent works in some cases, but I think this is a better way to get the child of a ConstraintLayout to fill its parent.

<android.support.constraint.ConstraintLayout
    android:layout_width="match_parent"
    android:layout_height="wrap_content">

    <ImageView
        android:layout_width="0dp"
        android:layout_height="0dp"
        app:layout_constraintStart_toStartOf="parent"
        app:layout_constraintEnd_toEndOf="parent"
        app:layout_constraintDimensionRatio="1:1"/>

</android.support.constraint.ConstraintLayout>

System is a final class from the java.lang package.

Attempting to provide some (possible) context for OP's question by posting my own trouble. I'm working in Scala, but the error messages I'm getting all reference Java types, and the error message reads a lot like the compiler complaining that CharSequence is not a String. I confirmed in the source code that String implements the CharSequence interface, but the error message draws attention to the difference between String and CharSequence while hiding the real source of the trouble:

scala> cols
res8: Iterable[String] = List(Item, a, b)

scala> val header = String.join(",", cols)
<console>:13: error: overloaded method value join with alternatives:
  (x$1: CharSequence,x$2: java.lang.Iterable[_ <: CharSequence])String <and>
  (x$1: CharSequence,x$2: CharSequence*)String
 cannot be applied to (String, Iterable[String])
       val header = String.join(",", cols)

I was able to fix this problem with the realization that the problem wasn't String / CharSequence, but rather a mismatch between java.lang.Iterable and Scala's built-in Iterable.

scala> val header = String.join(",", coll: _*)
header: String = Item,a,b

My particular problem can also be solved via the answers at Scala: join an iterable of strings

In summary, OP and others who come across similar problems should parse the error messages very closely and see what other type conversions might be involved.

Also, if you don't have the gradlew file in your current directory:

You can install gradle with homebrew with the following command:

$ brew install gradle

As mentioned in this answer. Then, you are not going to need to include it in your path (homebrew will take care of that) and you can just run (from any directory):

$ gradle test 

This is my initialState

    const initialStateInput = {
        cabeceraFamilia: {
            familia: '',
            direccion: '',
            telefonos: '',
            email: ''
        },
        motivoConsulta: '',
        fechaHora: '',
        corresponsables: [],
    }

The hook or you can replace it with the state (class component)

const [infoAgendamiento, setInfoAgendamiento] = useState(initialStateInput);

The method for handleChange

const actualizarState = e => {
    const nameObjects = e.target.name.split('.');
    const newState = setStateNested(infoAgendamiento, nameObjects, e.target.value);
    setInfoAgendamiento({...newState});
};

Method for set state with nested states

const setStateNested = (state, nameObjects, value) => {
    let i = 0;
    let operativeState = state;
    if(nameObjects.length > 1){
        for (i = 0; i < nameObjects.length - 1; i++) {
            operativeState = operativeState[nameObjects[i]];
        }
    }
    operativeState[nameObjects[i]] = value;
    return state;
}

Finally this is the input that I use

<input type="text" className="form-control" name="cabeceraFamilia.direccion" placeholder="Dirección" defaultValue={infoAgendamiento.cabeceraFamilia.direccion} onChange={actualizarState} />

Try \r\n in place of \n

The difference between \n and \r\n

It should be noted that this is applicable to line returns in emails. For other scenarios, please refer to rokjarc's answer.

~ For those using custom input box

Or use the XmlSerializer class.

XmlSerializer xs = new XmlSerializer(objectType);
obj = xs.Deserialize(new StringReader(yourXmlString));

if ( (strlen($ownerID) == 0) || ($ownerID == '0') || (empty($ownerID )) )

if $ownerID is NULL it will be triggered by the empty() test

https://www.php.net/empty

replace(convert(varchar, getdate(), 111), '/','-')

Will also do trick without "chopping anything off".

Both will work fine. I usually use script/runner.

Here's an example:

0 6 * * * cd /var/www/apps/your_app/current; ./script/runner --environment production 'EmailSubscription.send_email_subscriptions' >> /var/www/apps/your_app/shared/log/send_email_subscriptions.log 2>&1

You can also write a pure-Ruby script to do this if you load the right config files to connect to your database.

One thing to keep in mind if memory is precious is that script/runner (or a Rake task that depends on 'environment') will load the entire Rails environment. If you only need to insert some records into the database, this will use memory you don't really have to. If you write your own script, you can avoid this. I haven't actually needed to do this yet, but I am considering it.

For .NET Core:

string Token = Request.Headers["Custom"];

Or

{
   var m = headers.TryGetValue("Custom", out x);
}

Just for future needs.

In Visual Studio 2013 with .NET Framework 4.5, for a window property, try adding ElementName=window to make it work.

<Grid Name="myGrid" Height="437.274">
  <TextBox Text="{Binding Path=Name2, ElementName=window}"/>
</Grid>

you can also use:

pip install package==0.5.*

which is more consistent and easy to read.

your customComparator class must implement java.util.Comparator in order to be used. it must also overide compare() AND equals()

compare() must answer the question: Is object 1 less than, equal to or greater than object 2?

full docs: http://java.sun.com/j2se/1.5.0/docs/api/java/util/Comparator.html

Sometimes you just need to suppress only some warnings and you want to keep other warnings, just to be safe. In your code, you can suppress the warnings for variables and even formal parameters by using GCC's unused attribute. Lets say you have this code snippet:

void func(unsigned number, const int version)
{
  unsigned tmp;
  std::cout << number << std::endl;
}

There might be a situation, when you need to use this function as a handler - which (imho) is quite common in C++ Boost library. Then you need the second formal parameter version, so the function's signature is the same as the template the handler requires, otherwise the compilation would fail. But you don't really need it in the function itself either...

The solution how to mark variable or the formal parameter to be excluded from warnings is this:

void func(unsigned number, const int version __attribute__((unused)))
{
  unsigned tmp __attribute__((unused));
  std::cout << number << std::endl;
}

GCC has many other parameters, you can check them in the man pages. This also works for the C programs, not only C++, and I think it can be used in almost every function, not just handlers. Go ahead and try it! ;)

P.S.: Lately I used this to suppress warnings of Boosts' serialization in template like this:

template <typename Archive>
void serialize(Archive &ar, const unsigned int version __attribute__((unused)))

EDIT: Apparently, I didn't answer your question as you needed, drak0sha done it better. It's because I mainly followed the title of the question, my bad. Hopefully, this might help other people, who get here because of that title... :)

I can tell you the steps for installing purely via command line from scratch. I tested it on Ubuntu on 22 Feb 2021.

create sdk folder

export ANDROID_SDK_ROOT=/usr/lib/android-sdk
sudo mkdir -p $ANDROID_SDK_ROOT

install openjdk

sudo apt-get install openjdk-8-jdk

download android sdk

Go to https://developer.android.com/studio/index.html Then down to Command line tools only Click on Linux link, accept the agreement and instead of downloading right click and copy link address

cd $ANDROID_SDK_ROOT
sudo wget https://dl.google.com/android/repository/commandlinetools-linux-6858069_latest.zip
sudo unzip commandlinetools-linux-6858069_latest.zip

move folders

Rename the unpacked directory from cmdline-tools to tools, and place it under $ANDROID_SDK_ROOT/cmdline-tools, so now it should look like: $ANDROID_SDK_ROOT/cmdline-tools/tools. And inside it, you should have: NOTICE.txt bin lib source.properties.

set path

PATH=$PATH:$ANDROID_SDK_ROOT/cmdline-tools/latest/bin:$ANDROID_SDK_ROOT/cmdline-tools/tools/bin

This had no effect for me, hence the next step

browse to sdkmanager

cd $ANDROID_SDK_ROOT/cmdline-tools/tools/bin

accept licenses

yes | sudo sdkmanager --licenses

create build

Finally, run this inside your project

sudo ./gradlew assembleDebug

This creates an APK named -debug.apk at //build/outputs/apk/debug The file is already signed with the debug key and aligned with zipalign, so you can immediately install it on a device.

Since you specifically ask for software solutions, and you are using C++, why not use operator overloading to make your own, safe datatypes? For example:

Instead of using uint32_t (and double, int64_t etc), make your own SAFE_uint32_t which contains a multiple (minimum of 3) of uint32_t. Overload all of the operations you want (* + - / << >> = == != etc) to perform, and make the overloaded operations perform independently on each internal value, ie don't do it once and copy the result. Both before and after, check that all of the internal values match. If values don't match, you can update the wrong one to the value with the most common one. If there is no most-common value, you can safely notify that there is an error.

This way it doesn't matter if corruption occurs in the ALU, registers, RAM, or on a bus, you will still have multiple attempts and a very good chance of catching errors. Note however though that this only works for the variables you can replace - your stack pointer for example will still be susceptible.

A side story: I ran into a similar issue, also on an old ARM chip. It turned out to be a toolchain which used an old version of GCC that, together with the specific chip we used, triggered a bug in certain edge cases that would (sometimes) corrupt values being passed into functions. Make sure your device doesn't have any problems before blaming it on radio-activity, and yes, sometimes it is a compiler bug =)

<form onsubmit="return false;">
   ...
</form>

You will have to use a class, but don't worry, it's pretty simple. First we'll assign your :hover rules to not only apply to physically-hovered links, but also to links that have the classname hovered.

a:hover, a.hovered { color: #ccff00; }

Next, when you click #btn, we'll toggle the .hovered class on the #link.

$("#btn").click(function() {
   $("#link").toggleClass("hovered");
});

If the link has the class already, it will be removed. If it doesn't have the class, it will be added.

It only appeared in my Chrome browser a few days ago too. I checked a few websites I developed in the past that haven't been changed and they also show the same error. So I'd suggest it's not down to your coding, rather a bug in the latest Chrome release.

Just like CommonsWare suggested, make sure you have Gradle 2.2.1+ (the latest is 2.3).

Make sure you upgrade your Android Studio but here are the "plugins" that need to be updated:

Top build.gradle:

Change:

classpath 'com.android.tools.build:gradle:1.1.0-rc1'

To:

classpath 'com.android.tools.build:gradle:1.1.3' // latest 1.5.0

App build.gradle:

Change:

compile 'com.android.support:recyclerview-v7:21.0.0'
compile 'com.android.support:cardview-v7:21.0.0'

To:

compile 'com.android.support:recyclerview-v7:22.0.0' // latest 23.1.1
compile 'com.android.support:cardview-v7:22.0.0' // latest 23.1.1

Gradle: https://gradle.org/downloads

Always check the Android SDK Manager for the latest revisions:

Android Build Tools Plugin: http://tools.android.com/tech-docs/new-build-system

Android Support Libraries: http://developer.android.com/tools/support-library/features.html

To view the latest plugin releases, view the Bintray Jcenter page directly: https://bintray.com/android/android-tools/com.android.tools.build.gradle/view.

Swift 4 Solution-

Use this function

func image(with image: UIImage, scaledTo newSize: CGSize) -> UIImage {
    UIGraphicsBeginImageContextWithOptions(newSize, false, 1.0)
    image.draw(in: CGRect(x: 0, y: 0, width: newSize.width, height: newSize.height))
    let newImage = UIGraphicsGetImageFromCurrentImageContext()
    UIGraphicsEndImageContext()
    drawingImageView.image = newImage
    return newImage ?? UIImage()
}

Calling a function:-

image(with: predictionImage, scaledTo: CGSize(width: 28.0, height: 28.0)

here 28.0 is the pixel size that you want to set

Another way to solve this problem is to install the missing libs that you need.

You can download the libs and see how to install here.

This is not stated in the documentation, but to clear the opcode cache you must do:

apc_clear_cache('opcode');

EDIT: This seems to only apply to some older versions of APC..

No matter what version you are using you can't clear mod_php or fastcgi APC cache from a php cli script since the cli script will run from a different process as mod_php or fastcgi. You must call apc_clear_cache() from within the process (or child process) which you want to clear the cache for. Using curl to run a simple php script is one such approach.

I've just noticed that the answer that I upvoted and commented on is ambiguous. So the following is exactly what worked for me. I'm currently on Moment 2.26.0 and TS 3.8.3:

In code:

import moment from 'moment';

In TS config:

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

I am building for both CommonJS and EMS so this config is imported into other config files.

The insight comes from this answer which relates to using Express. I figured it was worth adding here though, to help anyone who searches in relation to Moment.js, rather than something more general.

The code snippet in the linked proposed duplicate reads user input.

ECHO A current build of Test Harness exists.
set /p delBuild=Delete preexisting build [y/n]?: 

The user can type as many letters as they want, and it will go into the delBuild variable.

In rpy2, the way to get the very same operator as "[" with R is to use ".rx". See the documentation about extracting with rpy2

For creating vectors, if you know your way around with Python there should not be any issue. See the documentation about creating vectors

If you search for an image base-64 converter, you can embed some small image texture files as code into your @import url('') section of code. It will look like a lot of code; but at least all your data is now stored locally - rather than having to call a separate resource to load the image.

When I take a file from my own inventory of a simple icon in PNG format, and convert it to base-64, it looks like this in my CSS:

there are some predefined sounds: SHUTTER_CLICK, FOCUS_COMPLETE, START_VIDEO_RECORDING, STOP_VIDEO_RECORDING.

Nice!

MediaActionSound

A class for producing sounds that match those produced by various actions taken by the media and camera APIs. Docs

use like:

fun playBeepSound() {
    val sound = MediaActionSound()
    sound.play(MediaActionSound.START_VIDEO_RECORDING)
}

if you have a data frame and want to remove all duplicates -- with reference to duplicates in a specific column (called 'colName'):

count before dedupe:

df.count()

do the de-dupe (convert the column you are de-duping to string type):

from pyspark.sql.functions import col
df = df.withColumn('colName',col('colName').cast('string'))

df.drop_duplicates(subset=['colName']).count()

can use a sorted groupby to check to see that duplicates have been removed:

df.groupBy('colName').count().toPandas().set_index("count").sort_index(ascending=False)

Another solution, you can do it using ResourceLoader like this:

import org.springframework.core.io.Resource;
import org.apache.commons.io.FileUtils;

@Autowire
private ResourceLoader resourceLoader;

...

Resource resource = resourceLoader.getResource("classpath:/path/to/you/dir");
File file = resource.getFile();
Iterator<File> fi = FileUtils.iterateFiles(file, null, true);
while(fi.hasNext()) {
    load(fi.next())
}

As in Internet Explorer, the javascript method "includes" doesn't support which is leading to the error as below

dijit.form.FilteringSelect TypeError: Object doesn't support property or method 'includes'

So I have changed the JavaScript string method from "includes" to "indexOf" as below

//str1 doesn't match str2 w.r.t index, so it will try to add object
var str1="acd", str2="b";
if(str1.indexOf(str2) == -1) 
{
  alert("add object");
}
else 
{
 alert("object not added");
}

For me this was the only thing that worked and it worked great:

RewriteCond %{HTTP_HOST}@@%{HTTP_REFERER} !^([^@])@@https?://\1/.
RewriteRule .(gif|jpg|jpeg|png|tif|pdf|wav|wmv|wma|avi|mov|mp4|m4v|mp3|zip?)$ - [F]

If you create Makefile in the VSCode, your makefile doesnt run. I don't know the cause of this issue. Maybe the configuration of the file is not added to system. But I solved this way. delete created makefile, then go to project directory and right click mouse later create a file and named Makefile. After fill the Makefile and run it. It will work.

Use LESS with Bootstrap...

Here are the Bootstrap docs for how to use LESS

(they have moved since previous answers)

<script>
    var listh = document.getElementById( 'list-home-list' );
    var hb = document.getElementsByTagName('hb');
    $("#list-home-list").click(function(){
    $(this).style.color = '#2C2E33';
    hb.style.color = 'white';
    });
</script>

The java application takes too long to respond(maybe due start-up/jvm being cold) thus you get the proxy error.

Proxy Error

The proxy server received an invalid response from an upstream server.
 The proxy server could not handle the request GET /lin/Campaignn.jsp.

As Albert Maclang said amending the http timeout configuration may fix the issue. I suspect the java application throws a 500+ error thus the apache gateway error too. You should look in the logs.

With minor corrections:

function rearrange()
{
var windowHeight;

if (typeof window.innerWidth != 'undefined')
{
    windowHeight = window.innerHeight;
}
// IE6 in standards compliant mode (i.e. with a valid doctype as the first
// line in the document)
else if (typeof document.documentElement != 'undefined'
        && typeof document.documentElement.clientWidth != 'undefined'
        && document.documentElement.clientWidth != 0)
{
    windowHeight = document.documentElement.clientHeight;
}
// older versions of IE
else
{
    windowHeight = document.getElementsByTagName('body')[0].clientHeight;
}

document.getElementById("foobar").style.height = (windowHeight - document.getElementById("foobar").offsetTop  - 6)+ "px";
}

Add a reference to Microsoft.VisualBasic to your project.

Then insert the using statement

using Microsoft.VisualBasic;

Use the defined constant vbCrLf:

private const string myString = "abc" + Constants.vbCrLf;

I have no idea what linux distribution "ubuntu centOS" is. Ubuntu and CentOS are two different distributions.

To answer the question in the header: To install make in ubuntu you have to install build-essentials

sudo apt-get install build-essential

Well, I have a tricky method for this job. The idea is as follow-

Make some invisible HTML tags like <label>, <p>, <input> etc. in HTML body and make a pattern in tag id, for example, use list index in tag id and list value at tag class name.

Here I have two lists maintenance_next[] and maintenance_block_time[] of the same length. I want to pass these two list's data to javascript using the flask. So I take some invisible label tag and set its tag name is a pattern of list index and set its class name as value at index.

{% for i in range(maintenance_next|length): %}_x000D_
<label id="maintenance_next_{{i}}" name="{{maintenance_next[i]}}" style="display: none;"></label>_x000D_
<label id="maintenance_block_time_{{i}}" name="{{maintenance_block_time[i]}}" style="display: none;"></label>_x000D_
{% endfor%}

After this, I retrieve the data in javascript using some simple javascript operation.

<script>_x000D_
var total_len = {{ total_len }};_x000D_
_x000D_
for (var i = 0; i < total_len; i++) {_x000D_
    var tm1 = document.getElementById("maintenance_next_" + i).getAttribute("name");_x000D_
    var tm2 = document.getElementById("maintenance_block_time_" + i).getAttribute("name");_x000D_
    _x000D_
    //Do what you need to do with tm1 and tm2._x000D_
    _x000D_
    console.log(tm1);_x000D_
    console.log(tm2);_x000D_
}_x000D_
</script>

The easiest solution is to just run your own counter thus:

int i = 0;
for (String s : stringArray) {
    doSomethingWith(s, i);
    i++;
}

The reason for this is because there's no actual guarantee that items in a collection (which that variant of for iterates over) even have an index, or even have a defined order (some collections may change the order when you add or remove elements).

See for example, the following code:

import java.util.*;

public class TestApp {
  public static void AddAndDump(AbstractSet<String> set, String str) {
    System.out.println("Adding [" + str + "]");
    set.add(str);
    int i = 0;
    for(String s : set) {
        System.out.println("   " + i + ": " + s);
        i++;
    }
  }

  public static void main(String[] args) {
    AbstractSet<String> coll = new HashSet<String>();
    AddAndDump(coll, "Hello");
    AddAndDump(coll, "My");
    AddAndDump(coll, "Name");
    AddAndDump(coll, "Is");
    AddAndDump(coll, "Pax");
  }
}

When you run that, you can see something like:

Adding [Hello]
   0: Hello
Adding [My]
   0: Hello
   1: My
Adding [Name]
   0: Hello
   1: My
   2: Name
Adding [Is]
   0: Hello
   1: Is
   2: My
   3: Name
Adding [Pax]
   0: Hello
   1: Pax
   2: Is
   3: My
   4: Name

indicating that, rightly so, order is not considered a salient feature of a set.

There are other ways to do it without a manual counter but it's a fair bit of work for dubious benefit.

Converting is easy, setting date and time is a little tricky. Here's an example:

Calendar cal = Calendar.getInstance();
cal.set(Calendar.YEAR, 2000);
cal.set(Calendar.MONTH, 0);
cal.set(Calendar.DAY_OF_MONTH, 1);
cal.set(Calendar.HOUR_OF_DAY, 1);
cal.set(Calendar.MINUTE, 1);
cal.set(Calendar.SECOND, 0);
cal.set(Calendar.MILLISECOND, 0);
stmt.setDate(1, new java.sql.Date(cal.getTimeInMillis()));

Using jQuery

$('#note textarea');

or just

$('#textid');

your maximum, minimum method is right

but you don't print int to console!

and... maybe better location change (maximum, minimum) methods

now (maximum, minimum) methods in the roop. it is need not.. just need one call

i suggest change this code

    for (int i = 0 ; i < array.length; i++ ) {
       int next = input.nextInt();
       // sentineil that will stop loop when 999 is entered
       if (next == 999)
       break;
       array[i] = next;
}
System.out.println("max Value : " + getMaxValue(array));
System.out.println("min Value : " + getMinValue(array));
System.out.println("These are the numbers you have entered.");
printArray(array);

public static void main(String[] args) {
         System.out.println(longestPalindromeString("9912333321456")); 
}

    static public String intermediatePalindrome(String s, int left, int right) {
        if (left > right) return null;
        while (left >= 0 && right < s.length()
                && s.charAt(left) == s.charAt(right)) {
            left--;
            right++;
        }
        return s.substring(left + 1, right);
    }


    public static String longestPalindromeString(String s) {
        if (s == null) return null;
        String longest = s.substring(0, 1);
        for (int i = 0; i < s.length() - 1; i++) {
            //odd cases like 121
            String palindrome = intermediatePalindrome(s, i, i);
            if (palindrome.length() > longest.length()) {
                longest = palindrome;
            }
            //even cases like 1221
            palindrome = intermediatePalindrome(s, i, i + 1);
            if (palindrome.length() > longest.length()) {
                longest = palindrome;
            }
        }
        return longest;
    }

There are many examples and also of different types for logging. Take a look at the java.util.logging package.

Example code:

import java.util.logging.Logger;

public class Main {

  private static Logger LOGGER = Logger.getLogger("InfoLogging");

  public static void main(String[] args) {
    LOGGER.info("Logging an INFO-level message");
  }
}

Without hard-coding the class name:

import java.util.logging.Logger;

public class Main {
  private static final Logger LOGGER = Logger.getLogger(
    Thread.currentThread().getStackTrace()[0].getClassName() );

  public static void main(String[] args) {
    LOGGER.info("Logging an INFO-level message");
  }
}

Correct, when you drag a view controller object onto your storyboard in order to create a new scene, it doesn't automatically make the new class for you, too.

Having added a new view controller scene to your storyboard, you then have to:

1. Create a UIViewController subclass. For example, go to your target's folder in the project navigator panel on the left and then control-click and choose "New File...". Choose a "Cocoa Touch Class":

   

   And then select a unique name for the new view controller subclass:

   

2. Specify this new subclass as the base class for the scene you just added to the storyboard.

   

3. Now hook up any IBOutlet and IBAction references for this new scene with the new view controller subclass.

When you use setcookie, you can either set the expiration time to 0 or simply omit the parametre - the cookie will then expire at the end of session (ie, when you close the browser).

You can convert the characters to integers and xor those instead:

l = [ord(a) ^ ord(b) for a,b in zip(s1,s2)]

Here's an updated function in case you need a string as a result of the XOR:

def sxor(s1,s2):    
    # convert strings to a list of character pair tuples
    # go through each tuple, converting them to ASCII code (ord)
    # perform exclusive or on the ASCII code
    # then convert the result back to ASCII (chr)
    # merge the resulting array of characters as a string
    return ''.join(chr(ord(a) ^ ord(b)) for a,b in zip(s1,s2))

I would like to add which isn't mentioned in above answers.

From your kibana's dev console, hit following command:

GET /

This is similar to accessing localhost:9200 from browser.

Hope this will help someone.

I use launch4j

ANT Command:

<target name="jar" depends="compile, buildDLLs, copy">
    <jar basedir="${java.bin.dir}" destfile="${build.dir}/Project.jar" manifest="META-INF/MANIFEST.MF" />
</target>

    <exec executable="cmd" dir="${launch4j.home}">

I've recently started using IntelliJ on my projects. However, some of my colleagues still use Eclipse on the same projects. Today, I've got the very same error after executing the jar-file created by my IntelliJ. While all the solutions in here talking about almost the same thing, none of them worked for me easily (possibly because I don't use ANT, maven build gave me other errors which referred me to http://cwiki.apache.org/confluence/display/MAVEN/MojoExecutionException, and also I couldn't figure out what are the signed jars by myself!)

Finally, this helped me

zip -d demoSampler.jar 'META-INF/*.SF' 'META-INF/*.RSA' 'META-INF/*SF'

Guess what's been removed from my jar file?!

deleting: META-INF/ECLIPSE_.SF 
deleting: META-INF/ECLIPSE_.RSA

It seems that the issue was relevant to some eclipse-relevant files.

Your test:

if (numberSet.length < 2) {
    return 0;
}

should be done before you allocate an array of that length in the below statement:

int[] differenceArray = new int[numberSet.length-1];

else you are already creating an array of size -1, when the numberSet.length = 0. That is quite odd. So, move your if statement as the first statement in your method.

There is an operator missing, likely a *:

-3.7 need_something_here (prof[x])

The "is not callable" occurs because the parenthesis -- and lack of operator which would have switched the parenthesis into precedence operators -- make Python try to call the result of -3.7 (a float) as a function, which is not allowed.

The parenthesis are also not needed in this case, the following may be sufficient/correct:

-3.7 * prof[x]

As Legolas points out, there are other things which may need to be addressed:

2.25 * (1 - math.pow(math.e, (-3.7(prof[x])/2.25))) * (math.e, (0/2.25)))
                                  ^-- op missing
                                                    extra parenthesis --^
               valid but questionable float*tuple --^
                                     expression yields 0.0 always --^

Use a regex. This one replaces the last dot, and everything after it.

String baseName = fileName.replaceAll("\\.[^.]*$", "");

You can also create a Pattern object if you want to precompile the regex.

It means the connection was successfully established at some point, but when you tried to commit right there, the connection was no longer open. The parameters you mentioned sound like connection pool settings. If so, they're unrelated to this problem. The most likely cause is a firewall between you and the database that is killing connections after a certain amount of idle time. The most common fix is to make your connection pool run a validation query when a connection is checked out from it. This will immediately identify and evict dead connnections, ensuring that you only get good connections out of the pool.

The biggest difference is their functionality. push_back always puts a new element at the end of the vector and insert allows you to select new element's position. This impacts the performance. vector elements are moved in the memory only when it's necessary to increase it's length because too little memory was allocated for it. On the other hand insert forces to move all elements after the selected position of a new element. You simply have to make a place for it. This is why insert might often be less efficient than push_back.

I had similar requirements but I didn't want to use v-model to have the state in the parent component. Then I got this to work:

<input
  type="checkbox"
  :checked="checked"
  @input="checked = $event.target.checked"
/>

To pass down the value from the parent, I made a small change on this and it works.

<input
  type="checkbox"
  :checked="aPropFrom"
  @input="$emit('update:aPropFrom', $event.target.checked)"
/>

401 means "Unauthorized", so there must be something with your credentials.

I think that java URL does not support the syntax you are showing. You could use an Authenticator instead.

Authenticator.setDefault(new Authenticator() {

    @Override
    protected PasswordAuthentication getPasswordAuthentication() {          
        return new PasswordAuthentication(login, password.toCharArray());
    }
});

and then simply invoking the regular url, without the credentials.

The other option is to provide the credentials in a Header:

String loginPassword = login+ ":" + password;
String encoded = new sun.misc.BASE64Encoder().encode (loginPassword.getBytes());
URLConnection conn = url.openConnection();
conn.setRequestProperty ("Authorization", "Basic " + encoded);

PS: It is not recommended to use that Base64Encoder but this is only to show a quick solution. If you want to keep that solution, look for a library that does. There are plenty.

I faced mostly the same issue. Im my case uuid is stored as BINARY(16) and has NOT NULL UNIQUE constraints. And i faced with the issue when the same UUID was generated for every row, and UNIQUE constraint does not allow this. So this query does not work:

UNHEX(REPLACE(uuid(), '-', ''))

But for me it worked, when i used such a query with nested inner select:

UNHEX(REPLACE((SELECT uuid()), '-', ''))

Then is produced unique result for every entry.

Faced same issue and solved by :

remove.packages("ggplot2")
install.packages('ggplot2', dependencies = TRUE)

Let's get definitive about AngularJS and SEO

Google, Yahoo, Bing, and other search engines crawl the web in traditional ways using traditional crawlers. They run robots that crawl the HTML on web pages, collecting information along the way. They keep interesting words and look for other links to other pages (these links, the amount of them and the number of them come into play with SEO).

So why don't search engines deal with javascript sites?

The answer has to do with the fact that the search engine robots work through headless browsers and they most often do not have a javascript rendering engine to render the javascript of a page. This works for most pages as most static pages don't care about JavaScript rendering their page, as their content is already available.

What can be done about it?

Luckily, crawlers of the larger sites have started to implement a mechanism that allows us to make our JavaScript sites crawlable, but it requires us to implement a change to our site.

If we change our hashPrefix to be #! instead of simply #, then modern search engines will change the request to use _escaped_fragment_ instead of #!. (With HTML5 mode, i.e. where we have links without the hash prefix, we can implement this same feature by looking at the User Agent header in our backend).

That is to say, instead of a request from a normal browser that looks like:

http://www.ng-newsletter.com/#!/signup/page

A search engine will search the page with:

http://www.ng-newsletter.com/?_escaped_fragment_=/signup/page

We can set the hash prefix of our Angular apps using a built-in method from ngRoute:

angular.module('myApp', [])
.config(['$location', function($location) {
  $location.hashPrefix('!');
}]);

And, if we're using html5Mode, we will need to implement this using the meta tag:

<meta name="fragment" content="!">

Reminder, we can set the html5Mode() with the $location service:

angular.module('myApp', [])
.config(['$location', 
function($location) {
  $location.html5Mode(true);
}]);

Handling the search engine

We have a lot of opportunities to determine how we'll deal with actually delivering content to search engines as static HTML. We can host a backend ourselves, we can use a service to host a back-end for us, we can use a proxy to deliver the content, etc. Let's look at a few options:

Self-hosted

We can write a service to handle dealing with crawling our own site using a headless browser, like phantomjs or zombiejs, taking a snapshot of the page with rendered data and storing it as HTML. Whenever we see the query string ?_escaped_fragment_ in a search request, we can deliver the static HTML snapshot we took of the page instead of the pre-rendered page through only JS. This requires us to have a backend that delivers our pages with conditional logic in the middle. We can use something like prerender.io's backend as a starting point to run this ourselves. Of course, we still need to handle the proxying and the snippet handling, but it's a good start.

With a paid service

The easiest and the fastest way to get content into search engine is to use a service Brombone, seo.js, seo4ajax, and prerender.io are good examples of these that will host the above content rendering for you. This is a good option for the times when we don't want to deal with running a server/proxy. Also, it's usually super quick.

For more information about Angular and SEO, we wrote an extensive tutorial on it at http://www.ng-newsletter.com/posts/serious-angular-seo.html and we detailed it even more in our book ng-book: The Complete Book on AngularJS. Check it out at ng-book.com.

Add *.DS_Store to your .gitignore file. That works for me perfectly

Try This,It's working perfect for me,

Follow below steps:

1. Define values in .h file.

     #define kNoOfColumsForCollection 3
     #define kNoOfRowsForCollection 4
     #define kcellSpace 5
     #define kCollectionViewCellWidth (self.view.frame.size.width - kcellSpace*kNoOfColumsForCollection)/kNoOfColumsForCollection
     #define kCollectionViewCellHieght (self.view.frame.size.height-40- kcellSpace*kNoOfRowsForCollection)/kNoOfRowsForCollection

OR

  #define kNoOfColumsForCollection 3
  #define kCollectionViewCellWidthHieght (self.view.frame.size.width - 6*kNoOfColumsForCollection)/kNoOfColumsForCollection

2.Add Code in collection View Layout data source methods as below,

 #pragma mark Collection View Layout data source methods
// collection view with autolayout

- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout minimumLineSpacingForSectionAtIndex:(NSInteger)section
{
return 4;
}

- (CGFloat)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout minimumInteritemSpacingForSectionAtIndex:(NSInteger)section
 {
 return 1;
}

- (UIEdgeInsets)collectionView:(UICollectionView *)collectionView layout:(UICollectionViewLayout*)collectionViewLayout insetForSectionAtIndex:(NSInteger)section
{
return UIEdgeInsetsMake(4, 4, 4, 4);
}
- (CGSize)collectionView:(UICollectionView *)collectionView
              layout:(UICollectionViewLayout *)collectionViewLayout
   sizeForItemAtIndexPath:(NSIndexPath *)indexPath
{
 return 
 CGSizeMake(kCollectionViewCellWidth,kCollectionViewCellHieght);
 // CGSizeMake (kCollectionViewCellWidthHieght,kCollectionViewCellWidthHieght);
}

Hope this will be help for some one.

return $query->join('kg_shops', function($join)

If you are using Bearing Token Auth, the above samples do not return an Application User.

Instead, use this:

ClaimsPrincipal currentUser = this.User;
var currentUserName = currentUser.FindFirst(ClaimTypes.NameIdentifier).Value;
ApplicationUser user = await _userManager.FindByNameAsync(currentUserName);

This works in apsnetcore 2.0. Have not tried in earlier versions.

Yes there are a couple of standards (albeit some liberties on the definition of standard) that have emerged:

1. JSON API - JSON API covers creating and updating resources as well, not just responses.
2. JSend - Simple and probably what you are already doing.
3. OData JSON Protocol - Very complicated.
4. HAL - Like OData but aiming to be HATEOAS like.

There are also JSON API description formats:

• Swagger
  • JSON Schema (used by swagger but you could use it stand alone)
• WADL in JSON
• RAML
• HAL because HATEOAS in theory is self describing.

So many answers doing half the work. Yes, !!X could be read as "the truthiness of X [represented as a boolean]". But !! isn't, practically speaking, so important for figuring out whether a single variable is (or even if many variables are) truthy or falsy. !!myVar === true is the same as just myVar. Comparing !!X to a "real" boolean isn't really useful.

What you gain with !! is the ability to check the truthiness of multiple variables against each other in a repeatable, standardized (and JSLint friendly) fashion.

Simply casting :(

That is...

• 0 === false is false.
• !!0 === false is true.

The above's not so useful. if (!0) gives you the same results as if (!!0 === false). I can't think of a good case for casting a variable to boolean and then comparing to a "true" boolean.

See "== and !=" from JSLint's directions (note: Crockford is moving his site around a bit; that link is liable to die at some point) for a little on why:

The == and != operators do type coercion before comparing. This is bad because it causes ' \t\r\n' == 0 to be true. This can mask type errors. JSLint cannot reliably determine if == is being used correctly, so it is best to not use == and != at all and to always use the more reliable === and !== operators instead.

If you only care that a value is truthy or falsy, then use the short form. Instead of
(foo != 0)

just say
(foo)

and instead of
(foo == 0)

say
(!foo)

Note that there are some unintuitive cases where a boolean will be cast to a number (true is cast to 1 and false to 0) when comparing a boolean to a number. In this case, !! might be mentally useful. Though, again, these are cases where you're comparing a non-boolean to a hard-typed boolean, which is, imo, a serious mistake. if (-1) is still the way to go here.

¦ if (-1) console.log("spam")           ¦ if (truthy)       ¦ spam      ¦ still best
+-----------------------------------------------------------------------+

And things get even crazier depending on your engine. WScript, for instance, wins the prize.

function test()
{
    return (1 === 1);
}
WScript.echo(test());

Because of some historical Windows jive, that'll output -1 in a message box! Try it in a cmd.exe prompt and see! But WScript.echo(-1 == test()) still gives you 0, or WScript's false. Look away. It's hideous.

Comparing truthiness :)

But what if I have two values I need to check for equal truthi/falsi-ness?

Pretend we have myVar1 = 0; and myVar2 = undefined;.

• myVar1 === myVar2 is 0 === undefined and is obviously false.
• !!myVar1 === !!myVar2 is !!0 === !!undefined and is true! Same truthiness! (In this case, both "have a truthiness of falsy".)

So the only place you'd really need to use "boolean-cast variables" would be if you had a situation where you're checking if both variables have the same truthiness, right? That is, use !! if you need to see if two vars are both truthy or both falsy (or not), that is, of equal (or not) truthiness.

I can't think of a great, non-contrived use case for that offhand. Maybe you have "linked" fields in a form?

if (!!customerInput.spouseName !== !!customerInput.spouseAge ) {
    errorObjects.spouse = "Please either enter a valid name AND age " 
        + "for your spouse or leave all spouse fields blank.";
}

So now if you have a truthy for both or a falsy for both spouse name and age, you can continue. Otherwise you've only got one field with a value (or a very early arranged marriage) and need to create an extra error on your errorObjects collection.

EDIT 24 Oct 2017, 6 Feb 19:

3rd party libraries that expect explicit Boolean values

Here's an interesting case... !! might be useful when 3rd party libs expect explicit Boolean values.

For instance, False in JSX (React) has a special meaning that's not triggered on simple falsiness. If you tried returning something like the following in your JSX, expecting an int in messageCount...

{messageCount && <div>You have messages!</div>}

... you might be surprised to see React render a 0 when you have zero messages. You have to explicitly return false for JSX not to render. The above statement returns 0, which JSX happily renders, as it should. It can't tell you didn't have Count: {messageCount && <div>Get your count to zero!</div>} (or something less contrived).

• One fix involves the bangbang, which coerces 0 into !!0, which is false:
  {!!messageCount && <div>You have messages!</div>}

• JSX' docs suggest you be more explicit, write self-commenting code, and use a comparison to force to a Boolean.
  {messageCount > 0 && <div>You have messages!</div>}

• I'm more comfortable handling falsiness myself with a ternary --
  {messageCount ? <div>You have messages!</div> : false}

Same deal in Typescript: If you have a function that returns a boolean (or you're assigning a value to a boolean variable), you [usually] can't return/assign a boolean-y value; it has to be a strongly typed boolean. This means, iff myObject is strongly typed, return !myObject; works for a function returning a boolean, but return myObject; doesn't. You have to return !!myObject to match Typescript's expectations.

The exception for Typescript? If myObject was an any, you're back in JavaScript's Wild West and can return it without !!, even if your return type is a boolean.

Keep in mind that these are JSX & Typescript conventions, not ones inherent to JavaScript.

But if you see strange 0s in your rendered JSX, think loose falsy management.

angualr uses the lighter version of jquery called as jqlite which means it doesnt have all the features of jQuery. here is a reference in angularjs docs about what you can use from jquery. Angular Element docs

In your case you need to find a div with ID or class name. for class name you can use

var elems =$element.find('div') //returns all the div's in the $elements
    angular.forEach(elems,function(v,k)){
    if(angular.element(v).hasClass('class-name')){
     console.log(angular.element(v));
}}

or you can use much simpler way by query selector

angular.element(document.querySelector('#id'))

angular.element(elem.querySelector('.classname'))

it is not as flexible as jQuery but what

If by whitespaces you mean the ' ' character, my suggestion would just be a search/replace. As the others have hinted, set list changes non printing characters to a visible character that's configured in listchars.

To explicitly show spaces as some other character, something similar to the below should do the trick:

:%s/ /¦/g

Then just undo the change to go back again.

(to get the ¦ I pressed this exact key sequence: :%s/ /CTRL-KFB/g)

Here is another take on the same thing which worked better for the situation I was in. It solves the problem where you have more than one remote, would like to clone all branches in remote source to remote destination but without having to check them all out beforehand.

(The problem I had with Daniel's solution was that it would refuse to checkout a tracking branch from the source remote if I had previously checked it out already, ie, it would not update my local branch before the push)

git push destination +refs/remotes/source/*:refs/heads/*

Note: If you are not using direct CLI, you must escape the asterisks:

git push destination +refs/remotes/source/\*:refs/heads/\*

• @mattalxndr

this will push all branches in remote source to a head branch in destination, possibly doing a non-fast-forward push. You still have to push tags separately.

I had precisely this problem, but I needed sequential plots to have highly contrasting color. I was also doing plots with a common sub-plot containing reference data, so I wanted the color sequence to be consistently repeatable.

I initially tried simply generating colors randomly, reseeding the RNG before each plot. This worked OK (commented-out in code below), but could generate nearly indistinguishable colors. I wanted highly contrasting colors, ideally sampled from a colormap containing all colors.

I could have as many as 31 data series in a single plot, so I chopped the colormap into that many steps. Then I walked the steps in an order that ensured I wouldn't return to the neighborhood of a given color very soon.

My data is in a highly irregular time series, so I wanted to see the points and the lines, with the point having the 'opposite' color of the line.

Given all the above, it was easiest to generate a dictionary with the relevant parameters for plotting the individual series, then expand it as part of the call.

Here's my code. Perhaps not pretty, but functional.

from matplotlib import cm
cmap = cm.get_cmap('gist_rainbow')  #('hsv') #('nipy_spectral')

max_colors = 31   # Constant, max mumber of series in any plot.  Ideally prime.
color_number = 0  # Variable, incremented for each series.

def restart_colors():
    global color_number
    color_number = 0
    #np.random.seed(1)

def next_color():
    global color_number
    color_number += 1
    #color = tuple(np.random.uniform(0.0, 0.5, 3))
    color = cmap( ((5 * color_number) % max_colors) / max_colors )
    return color

def plot_args():  # Invoked for each plot in a series as: '**(plot_args())'
    mkr = next_color()
    clr = (1 - mkr[0], 1 - mkr[1], 1 - mkr[2], mkr[3])  # Give line inverse of marker color
    return {
        "marker": "o",
        "color": clr,
        "mfc": mkr,
        "mec": mkr,
        "markersize": 0.5,
        "linewidth": 1,
    }

My context is JupyterLab and Pandas, so here's sample plot code:

restart_colors()  # Repeatable color sequence for every plot

fig, axs = plt.subplots(figsize=(15, 8))
plt.title("%s + T-meter"%name)

# Plot reference temperatures:
axs.set_ylabel("°C", rotation=0)
for s in ["T1", "T2", "T3", "T4"]:
    df_tmeter.plot(ax=axs, x="Timestamp", y=s, label="T-meter:%s" % s, **(plot_args()))

# Other series gets their own axis labels
ax2 = axs.twinx()
ax2.set_ylabel(units)

for c in df_uptime_sensors:
    df_uptime[df_uptime["UUID"] == c].plot(
        ax=ax2, x="Timestamp", y=units, label="%s - %s" % (units, c), **(plot_args())
    )

fig.tight_layout()
plt.show()

The resulting plot may not be the best example, but it becomes more relevant when interactively zoomed in.

window.top.location.href = 'index.html';

This will redirect the main window to the index page. Thanks

This query should work for you:

SELECT *
FROM table
WHERE MONTH(columnName) = MONTH(CURRENT_DATE())
AND YEAR(columnName) = YEAR(CURRENT_DATE())

For me it was just a problem of permissions on the persistent redis data folder. I gave it a:

chmod 777 -Rf data/

And it's works ! May be it's early to say it's resolve the issue. Because I also suspect that redis is not executing as root so I need to inspect my dockerFile to figure out more.

We do it differently. IMHO we do it in an easier way: in master we are working on the next major version.

Each larger feature gets its own branch (derived from master) and will be rebased (+ force pushed) on top of master regularly by the developer. Rebasing only works fine if a single developer works on this feature. If the feature is finished, it will be freshly rebased onto master and then the master fast-forwarded to the latest feature commit.

To avoid the rebasing/forced push one also can merge master changes regularly to the feature branch and if it's finished merge the feature branch into master (normal merge or squash merge). But IMHO this makes the feature branch less clear and makes it much more difficult to reorder/cleanup the commits.

If a new release is coming, we create a side-branch out of master, e.g. release-5 where only bugs get fixed.

Try this

$data1 = strtotime(\date("d/m/Y"));
$data1 = date_create($data1);
$data2 = date_create("21/06/2017");

if($data1 < $data2){
    return "The most current date is date1";
}

return "The most current date is date2";

If you are certain that the script runs in the first hours of the day, you can simply do

  date -d "12 hours ago" '+%Y-%m-%d'

BTW, if the script runs daily at 00:35 (via crontab?) you should ask yourself what will happen if a DST change falls in that hour; the script could not run, or run twice in some cases. Modern implementations of cron are quite clever in this regard, though.

Instead of IN we can use ANY with arrays casted to enum array, for example:

create type example_enum as enum (
  'ENUM1', 'ENUM2'
);

create table example_table (
  id integer,
  enum_field example_enum
);

select 
  * 
from 
  example_table t
where
  t.enum_field = any(array['ENUM1', 'ENUM2']::example_enum[]);

Or we can still use 'IN' clause, but first, we should 'unnest' it:

select 
  * 
from 
  example_table t
where
  t.enum_field in (select unnest(array['ENUM1', 'ENUM2']::example_enum[]));

Example: https://www.db-fiddle.com/f/LaUNi42HVuL2WufxQyEiC/0

This should handle cases of clicking on [x] or ALT+F4

private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
   if (e.CloseReason == CloseReason.UserClosing)
   {
      DialogResult result = MessageBox.Show("Do you really want to exit?", "Dialog Title", MessageBoxButtons.YesNo);
      if (result == DialogResult.Yes)
      {
          Environment.Exit(0);
      }
      else 
      {
         e.Cancel = true;
      }
   }
   else
   {
      e.Cancel = true;
   }
}   

Solved myself. Done some small structural changes also. Route from Component1 to Component2 is done by a single <router-outlet>. Component2 to Comonent3 and Component4 is done by multiple <router-outlet name= "xxxxx"> The resulting contents are :

Component1.html

<nav>
    <a routerLink="/two" class="dash-item">Go to 2</a>
</nav>
    <router-outlet></router-outlet>

Component2.html

 <a [routerLink]="['/two', {outlets: {'nameThree': ['three']}}]">In Two...Go to 3 ...       </a>
 <a [routerLink]="['/two', {outlets: {'nameFour': ['four']}}]">   In Two...Go to 4 ...</a>

 <router-outlet name="nameThree"></router-outlet>
 <router-outlet name="nameFour"></router-outlet>

The '/two' represents the parent component and ['three']and ['four'] represents the link to the respective children of component2 . Component3.html and Component4.html are the same as in the question.

router.module.ts

const routes: Routes = [
{
    path: '',
    redirectTo: 'one',
    pathMatch: 'full'
},
{
    path: 'two',
    component: ClassTwo, children: [

        {
            path: 'three',
            component: ClassThree,
            outlet: 'nameThree'
        },
        {
            path: 'four',
            component: ClassFour,
            outlet: 'nameFour'
        }
    ]
},];

Among the answers given here before this one, the one by "Yes Barry" is the most appropriate one.

random_int(100000, 999999)

Note that here we use random_int, which was introduced in PHP 7 and uses a cryptographic random generator, something that is important if you want random codes to be hard to guess. random_bytes was also introduced in PHP 7 and likewise uses a cryptographic random generator.

Many other solutions for random value generation, including those involving time(), microtime(), uniqid(), rand(), mt_rand(), str_shuffle(), and array_rand(), are much more predictable and are unsuitable if the random string will serve as a password, a bearer credential, a nonce, a session identifier, a "verification code" or "confirmation code", or another secret value.

The code above generates a string of 6 decimal digits. If you want to use a bigger character set (such as all upper-case letters, all lower-case letters, and the 10 digits), this is a more involved process, but you have to use random_int or random_bytes rather than rand(), mt_rand(), str_shuffle(), etc., if the string will serve as a password, a "confirmation code", or another secret value. See an answer to a related question, and see also: generating a random code in php?

I also list other things to keep in mind when generating unique identifiers, especially random ones.

                        Log.e("JSON Parser3", "Error parsing data [" + e3.getMessage()+"] "+json);
                        Log.e("JSON Parser3", "Error parsing data " + e3.toString());
                    }
                }
            }
        }
    }

    // return JSON String
    return jObj;

I found the terms of use from Google Map:

Section 10.5

No caching or storage. You will not pre-fetch, cache, index, or store any Content to be used outside the Service, except that you may store limited amounts of Content solely for the purpose of improving the performance of your Maps API Implementation due to network latency (and not for the purpose of preventing Google from accurately tracking usage), and only if such storage: is temporary (and in no event more than 30 calendar days); is secure; does not manipulate or aggregate any part of the Content or Service; and does not modify attribution in any way.

It means we can cache for limited time actually

In Laravel 5.4 the following worked for me:

return back()->withErrors(['field_name' => ['Your custom message here.']]);

Not sure if this does all expected things, but you can do just like that:

>>> del mymodule
>>> import mymodule

And what about it?:

ImageIcon imageIcon = new ImageIcon(new ImageIcon("icon.png").getImage().getScaledInstance(20, 20, Image.SCALE_DEFAULT));
label.setIcon(imageIcon);

From: Resize a picture to fit a JLabel

Please modify this method according to your need. This worked for me!

  private boolean validateMobilenumber() {
        if (mobilenumber.getText().toString().trim().isEmpty() || mobilenumber.getText().toString().length() < 10) {
            input_layout_mobilenumber.setErrorEnabled(true);
            input_layout_mobilenumber.setError(getString(R.string.err_msg_mobilenumber));
           // requestFocus(mobilenumber);
            return false;
        } else {
            input_layout_mobilenumber.setError(null);
            input_layout_mobilenumber.setErrorEnabled(false);
            mobilenumber.setBackground(mobilenumber.getBackground().getConstantState().newDrawable());
        }

I had same error and the mistake was that I had added list and dictionary into the same list (object) and when I used to iterate over the list of dictionaries and use to hit a list (type) object then I used to get this error.

Its was a code error and made sure that I only added dictionary objects to that list and list typed object into the list, this solved my issue as well.

Ajax.ActionLink only sends an ajax request to the server. What happens ahead really depends upon type of data returned and what your client side script does with it. You may send a partial view for ajax call or json, xml etc. Ajax.ActionLink however have different callbacks and parameters that allow you to write js code on different events. You can do something before request is sent or onComplete. similarly you have an onSuccess callback. This is where you put your JS code for manipulating result returned by server. You may simply put it back in UpdateTargetID or you can do fancy stuff with this result using jQuery or some other JS library.

If we are not sure that the list is sorted, we could use the built-in min() function, to find the element which has the minimum distance from the specified number.

>>> min(myList, key=lambda x:abs(x-myNumber))
4

Note that it also works with dicts with int keys, like {1: "a", 2: "b"}. This method takes O(n) time.

If the list is already sorted, or you could pay the price of sorting the array once only, use the bisection method illustrated in @Lauritz's answer which only takes O(log n) time (note however checking if a list is already sorted is O(n) and sorting is O(n log n).)

min_element and max_element return iterators, not values. So you need *min_element... and *max_element....

Do you want to disable error reporting, or just prevent the user from seeing it? It’s usually a good idea to log errors, even on a production site.

# in your PHP code:
ini_set('display_errors', '0');     # don't show any errors...
error_reporting(E_ALL | E_STRICT);  # ...but do log them

They will be logged to your standard system log, or use the error_log directive to specify exactly where you want errors to go.

I had the same problem, needed a modification of [Required] attribute - make field required in dependence of http request.The solution was similar to Dan Hunex answer, but his solution didn't work correctly (see comments). I don't use unobtrusive validation, just MicrosoftMvcValidation.js out of the box. Here it is. Implement your custom attribute:

public class RequiredIfAttribute : RequiredAttribute
{

    public RequiredIfAttribute(/*You can put here pararmeters if You need, as seen in other answers of this topic*/)
    {

    }

    protected override ValidationResult IsValid(object value, ValidationContext context)
    {

    //You can put your logic here   

        return ValidationResult.Success;//I don't need its server-side so it always valid on server but you can do what you need
    }


}

Then you need to implement your custom provider to use it as an adapter in your global.asax

public class RequreIfValidator : DataAnnotationsModelValidator <RequiredIfAttribute>
{

    ControllerContext ccontext;
    public RequreIfValidator(ModelMetadata metadata, ControllerContext context, RequiredIfAttribute attribute)
       : base(metadata, context, attribute)
    {
        ccontext = context;// I need only http request
    }

//override it for custom client-side validation 
     public override IEnumerable<ModelClientValidationRule> GetClientValidationRules()
     {       
               //here you can customize it as you want
         ModelClientValidationRule rule = new ModelClientValidationRule()
         {
             ErrorMessage = ErrorMessage,
    //and here is what i need on client side - if you want to make field required on client side just make ValidationType "required"    
             ValidationType =(ccontext.HttpContext.Request["extOperation"] == "2") ? "required" : "none";
         };
         return new ModelClientValidationRule[] { rule };
      }
}

And modify your global.asax with a line

DataAnnotationsModelValidatorProvider.RegisterAdapter(typeof(RequiredIfAttribute), typeof(RequreIfValidator));

and here it is

[RequiredIf]
public string NomenclatureId { get; set; }

The main advantage for me is that I don't have to code custom client validator as in case of unobtrusive validation. it works just as [Required], but only in cases that you want.

result = initial number + (6 - initial number % 6)

I just had same error. I had year 2015 in app id. I replaced 2015 by fifteen and that solved it.

Also, if you use Android Studio, you can try: Tools / Android / Synch Project with Gradle Files

Make sure you change the right info.plist file.

This is the second time I waste time on this issue, because I didn't notice that I'm changing info.plist under MyProjectNameUITests.

There may be situations when df.reset_index() cannot be used (e.g., when you need the index, too). In this case, use index.get_level_values() to access index values directly:

df['Trial'] = df.index.get_level_values(0)
df['measurement'] = df.index.get_level_values(1)

This will assign index values to individual columns and keep the index.

See the docs for further info.

There are two type of paths: absolute and relative. This is basically the same for files in your hard disc and directories in a URL.

Absolute paths start with a leading slash. They always point to the same location, no matter where you use them:

• /pages/en/faqs/faq-page1.html

Relative paths are the rest (all that do not start with slash). The location they point to depends on where you are using them

• index.html is:
  • /pages/en/faqs/index.html if called from /pages/en/faqs/faq-page1.html
  • /pages/index.html if called from /pages/example.html
  • etc.

There are also two special directory names: . and ..:

• . means "current directory"
• .. means "parent directory"

You can use them to build relative paths:

• ../index.html is /pages/en/index.html if called from /pages/en/faqs/faq-page1.html
• ../../index.html is /pages/index.html if called from /pages/en/faqs/faq-page1.html

Once you're familiar with the terms, it's easy to understand what it's failing and how to fix it. You have two options:

• Use absolute paths
• Fix your relative paths

SQL Server drops and recreates the tables only if you:

• Add a new column
• Change the Allow Nulls setting for a column
• Change the column order in the table
• Change the column data type

Using ALTER is safer, as in case the metadata is lost while you re-create the table, your data will be lost.

You could use a bash array:

files=(*.pdf)
for((I=0;I<${#files[@]};I+=1000)); do
    rm -f "${files[@]:I:1000}"
done

This way it will erase in batches of 1000 files per step.

as per @cyberbikepunk answer pycharm supports Anaconda since pycharm5!

Have a look how easy is to add an environment:

I had this same issue and it turned out that it was because I had renamed the project. I went into the project properties and changed the Assembly Name and Root Namespace to the project name and it worked great after that!

If you use the Bootstrap Collapse class sometimes {!! $text !!} is not worked for me but {{ html_entity_decode($text) }} is worked for me.

There is very simple solution to this problem in the hablar package:

library(hablar)

dat %>% rationalize()

Which return a data frame with all Inf are converted to NA.

Timings compared to some above solutions. Code: library(hablar) library(data.table)

dat <- data.frame(a = rep(c(1,Inf), 1e6), b = rep(c(Inf,2), 1e6), 
                  c = rep(c('a','b'),1e6),d = rep(c(1,Inf), 1e6),  
                  e = rep(c(Inf,2), 1e6))
DT <- data.table(dat)

system.time(dat[mapply(is.infinite, dat)] <- NA)
system.time(dat[dat==Inf] <- NA)
system.time(invisible(lapply(names(DT),function(.name) set(DT, which(is.infinite(DT[[.name]])), j = .name,value =NA))))
system.time(rationalize(dat))

Result:

> system.time(dat[mapply(is.infinite, dat)] <- NA)
   user  system elapsed 
  0.125   0.039   0.164 
> system.time(dat[dat==Inf] <- NA)
   user  system elapsed 
  0.095   0.010   0.108 
> system.time(invisible(lapply(names(DT),function(.name) set(DT, which(is.infinite(DT[[.name]])), j = .name,value =NA))))
   user  system elapsed 
  0.065   0.002   0.067 
> system.time(rationalize(dat))
   user  system elapsed 
  0.058   0.014   0.072 
> 

Seems like data.table is faster than hablar. But has longer syntax.

Note: The widely used solution above is based on displayMetrics.density. However, the docs explain that this value is a rounded value, used with the screen 'buckets'. Eg. on my Nexus 10 it returns 2, where the real value would be 298dpi (real) / 160dpi (default) = 1.8625.

Depending on your requirements, you might need the exact transformation, which can be achieved like this:

[Edit] This is not meant to be mixed with Android's internal dp unit, as this is of course still based on the screen buckets. Use this where you want a unit that should render the same real size on different devices.

Convert dp to pixel:

public int dpToPx(int dp) {
    DisplayMetrics displayMetrics = getContext().getResources().getDisplayMetrics();
    return Math.round(dp * (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT));     
}

Convert pixel to dp:

public int pxToDp(int px) {
    DisplayMetrics displayMetrics = getContext().getResources().getDisplayMetrics();
    return Math.round(px / (displayMetrics.xdpi / DisplayMetrics.DENSITY_DEFAULT));
}

Note that there are xdpi and ydpi properties, you might want to distinguish, but I can't imagine a sane display where these values differ greatly.

This an old question, but I have had to explain it to someone recently and I thought recording the answer here would be helpful at least in understanding how C works.

String literals like

"a"

or

"This is a string"

are put in the text or data segments of your program.

A string in C is actually a pointer to a char, and the string is understood to be the subsequent chars in memory up until a NUL char is encountered. That is, C doesn't really know about strings.

So if I have

char *s1 = "This is a string";

then s1 is a pointer to the first byte of the string.

Now, if I have

char *s2 = "This is a string";

this is also a pointer to the same first byte of that string in the text or data segment of the program.

But if I have

char *s3 = malloc( 17 );
strcpy(s3, "This is a string");

then s3 is a pointer to another place in memory into which I copy all the bytes of the other strings.

Illustrative examples:

Although, as your compiler rightly points out, you shouldn't do this, the following will evaluate to true:

s1 == s2 // True: we are comparing two pointers that contain the same address

but the following will evaluate to false

s1 == s3 // False: Comparing two pointers that don't hold the same address.

And although it might be tempting to have something like this:

struct Vehicle{
    char *type;
    // other stuff
}

if( type == "Car" )
   //blah1
else if( type == "Motorcycle )
   //blah2

You shouldn't do it because it's not something that is guarantied to work. Even if you know that type will always be set using a string literal.

I have tested it and it works. If I do

A.type = "Car";

then blah1 gets executed and similarly for "Motorcycle". And you'd be able to do things like

if( A.type == B.type )

but this is just terrible. I'm writing about it because I think it's interesting to know why it works, and it helps understand why you shouldn't do it.

Solutions:

In your case, what you want to do is use strcmp(a,b) == 0 to replace a == b

In the case of my example, you should use an enum.

enum type {CAR = 0, MOTORCYCLE = 1}

The preceding thing with string was useful because you could print the type, so you might have an array like this

char *types[] = {"Car", "Motorcycle"};

And now that I think about it, this is error prone since one must be careful to maintain the same order in the types array.

Therefore it might be better to do

char *getTypeString(int type)
{
    switch(type)
    case CAR: return "Car";
    case MOTORCYCLE: return "Motorcycle"
    default: return NULL;
}

got it solved by first creating new "Path" variable under User variables (note that after fresh windows install Path variable is not created as User variable, only as system) after that, I appended %M2% (pointing to maven dir/bin) to (freshly created) user Path variable. after that restarted cmd window and it worked like a charm.

It seems that the DateTimeSpan solution pleases a lot of people. I don't know. Let's consider the:

BeginDate = 1972/2/29 EndDate = 1972/4/28.

The DateTimeSpan based answer is:

1 year(s), 2 month(s) and 0 day(s)

I implemented a method and based on that the answer is:

1 year(s), 1 month(s) and 28 day(s)

Clearly there are not 2 full months there. I would say that because we are at the end of the month of the begin date what's left is actually the full month of March plus the number of days passed in the month of the end date (April), so 1 month and 28 days.

If you read so far and you are intrigued I posted the method below. I am explaining in the comments the assumptions I make because how many months, the concept of months is such a moving target. Test it many times and see if the answers make sense. I usually choose test dates in adjacent years and once I verify an answer I move a day or two back and forth. So far it looks good, I'm sure you'll find some bugs :D. The code might look a bit rough but I hope it is clear enough:

static void Main(string[] args) {
        DateTime EndDate = new DateTime(1973, 4, 28);
        DateTime BeginDate = new DateTime(1972, 2, 29);
        int years, months, days;
        GetYearsMonthsDays(EndDate, BeginDate, out years, out months, out days);
        Console.WriteLine($"{years} year(s), {months} month(s) and {days} day(s)");
    }

    /// <summary>
    /// Calculates how many years, months and days are between two dates.
    /// </summary>
    /// <remarks>
    /// The fundamental idea here is that most of the time all of us agree
    /// that a month has passed today since the same day of the previous month.
    /// A particular case is when both days are the last days of their respective months 
    /// when again we can say one month has passed.
    /// In the following cases the idea of a month is a moving target.
    /// - When only the beginning date is the last day of the month then we're left just with 
    /// a number of days from the next month equal to the day of the month that end date represent
    /// - When only the end date is the last day of its respective month we clearly have a 
    /// whole month plus a few days after the the day of the beginning date until the end of its
    /// respective months
    /// In all the other cases we'll check
    /// - beginingDay > endDay -> less then a month just daysToEndofBeginingMonth + dayofTheEndMonth
    /// - beginingDay < endDay -> full month + (endDay - beginingDay)

    private static void GetYearsMonthsDays(DateTime EndDate, DateTime BeginDate, out int years, out int months, out int days ) {
        var beginMonthDays = DateTime.DaysInMonth(BeginDate.Year, BeginDate.Month);
        var endMonthDays = DateTime.DaysInMonth(EndDate.Year, EndDate.Month);
        // get the full years
        years = EndDate.Year - BeginDate.Year - 1;
        // how many full months in the first year

        if(beginMonthDays == BeginDate.Day && endMonthDays == EndDate.Day) {
            months++;
        }
        else if(beginMonthDays == BeginDate.Day) {

        }
        else if(endMonthDays == EndDate.Day) {

        }
        // For all the other cases
        else if(EndDate.Day > BeginDate.Day) {
            months++;
            days += EndDate.Day - BeginDate.Day;

        }
        if(months >= 12) {
            years++;
            months = months - 12;
        }
    }

Main issue is that you first need to set the location of your x and y ticks. Also, it helps to use the more object-oriented interface to matplotlib. Namely, interact with the axes object directly.

import matplotlib.pyplot as plt
import numpy as np
column_labels = list('ABCD')
row_labels = list('WXYZ')
data = np.random.rand(4,4)
fig, ax = plt.subplots()
heatmap = ax.pcolor(data)

# put the major ticks at the middle of each cell, notice "reverse" use of dimension
ax.set_yticks(np.arange(data.shape[0])+0.5, minor=False)
ax.set_xticks(np.arange(data.shape[1])+0.5, minor=False)


ax.set_xticklabels(row_labels, minor=False)
ax.set_yticklabels(column_labels, minor=False)
plt.show()

Hope that helps.
