Or you can simply use PRINT command instead of SELECT command. Try this,

PRINT dbo.fn_HomePageSlider(9, 3025)

Your nameContent variable is inside the function scope and not visible outside that function so if you want to use the nameContent outside of the function then declare it global inside the <script> tag and use inside functions without the var keyword as follows

<script language="javascript" type="text/javascript">
    var nameContent; // In the global scope
    function first(){
        nameContent=document.getElementById('full_name').value;
    }

    function second() {
        first();
        y=nameContent; 
        alert(y);
    }
    second();
</script>

The straightforward way to do this correctly and securely is to use Open3.capture2(), Open3.capture2e(), or Open3.capture3().

Using ruby's backticks and its %x alias are NOT SECURE UNDER ANY CIRCUMSTANCES if used with untrusted data. It is DANGEROUS, plain and simple:

untrusted = "; date; echo"
out = `echo #{untrusted}`                              # BAD

untrusted = '"; date; echo"'
out = `echo "#{untrusted}"`                            # BAD

untrusted = "'; date; echo'"
out = `echo '#{untrusted}'`                            # BAD

The system function, in contrast, escapes arguments properly if used correctly:

ret = system "echo #{untrusted}"                       # BAD
ret = system 'echo', untrusted                         # good

Trouble is, it returns the exit code instead of the output, and capturing the latter is convoluted and messy.

The best answer in this thread so far mentions Open3, but not the functions that are best suited for the task. Open3.capture2, capture2e and capture3 work like system, but returns two or three arguments:

out, err, st = Open3.capture3("echo #{untrusted}")     # BAD
out, err, st = Open3.capture3('echo', untrusted)       # good
out_err, st  = Open3.capture2e('echo', untrusted)      # good
out, st      = Open3.capture2('echo', untrusted)       # good
p st.exitstatus

Another mentions IO.popen(). The syntax can be clumsy in the sense that it wants an array as input, but it works too:

out = IO.popen(['echo', untrusted]).read               # good

For convenience, you can wrap Open3.capture3() in a function, e.g.:

#
# Returns stdout on success, false on failure, nil on error
#
def syscall(*cmd)
  begin
    stdout, stderr, status = Open3.capture3(*cmd)
    status.success? && stdout.slice!(0..-(1 + $/.size)) # strip trailing eol
  rescue
  end
end

Example:

p system('foo')
p syscall('foo')
p system('which', 'foo')
p syscall('which', 'foo')
p system('which', 'which')
p syscall('which', 'which')

Yields the following:

nil
nil
false
false
/usr/bin/which         <— stdout from system('which', 'which')
true                   <- p system('which', 'which')
"/usr/bin/which"       <- p syscall('which', 'which')

I just stumbled upon a usage of __call__() in concert with __getattr__() which I think is beautiful. It allows you to hide multiple levels of a JSON/HTTP/(however_serialized) API inside an object.

The __getattr__() part takes care of iteratively returning a modified instance of the same class, filling in one more attribute at a time. Then, after all information has been exhausted, __call__() takes over with whatever arguments you passed in.

Using this model, you can for example make a call like api.v2.volumes.ssd.update(size=20), which ends up in a PUT request to https://some.tld/api/v2/volumes/ssd/update.

The particular code is a block storage driver for a certain volume backend in OpenStack, you can check it out here: https://github.com/openstack/cinder/blob/master/cinder/volume/drivers/nexenta/jsonrpc.py

EDIT: Updated the link to point to master revision.

Prefix the call with Module2 (ex. Module2.IDLE). I'm assuming since you asked this that you have IDLE defined multiple times in the project, otherwise this shouldn't be necessary.

Assuming that call_me is a global function, so you don't expect this to be set.

var x = ['p0', 'p1', 'p2'];
call_me.apply(null, x);

class test {
    public newTest(){
        $this->bigTest();
        $this->smallTest();
    }

    private  function bigTest(){
        //Big Test Here
    }

    private function smallTest(){
       //Small Test Here
    }

    public scoreTest(){
      //Scoring code here;
    }
 }

Try -

Call CatSubProduktAreakum(Stattyp, Daty + UBound(SubCategories) + 2)

As for the reason, this from MSDN via this question - What does the Call keyword do in VB6?

You are not required to use the Call keyword when calling a procedure. However, if you use the Call keyword to call a procedure that requires arguments, argumentlist must be enclosed in parentheses. If you omit the Call keyword, you also must omit the parentheses around argumentlist. If you use either Call syntax to call any intrinsic or user-defined function, the function's return value is discarded.

With quotes around the date:

mysql> CALL insertEvent('2012.01.01 12:12:12');

You should use the following code :

Class2 cls2 = new Class2();
cls2.UpdateEmployee();

In case you don't want to create a new instance to call the method, you can decalre the method as static and then you can just call Class2.UpdateEmployee().

Simply create an instance of Class2 and call the desired method.

class Foo          (object):
    # ^class name  #^ inherits from object

    bar = "Bar" #Class attribute.

    def __init__(self):
        #        #^ The first variable is the class instance in methods.  
        #        #  This is called "self" by convention, but could be any name you want.
        #^ double underscore (dunder) methods are usually special.  This one 
        #  gets called immediately after a new instance is created.

        self.variable = "Foo" #instance attribute.
        print self.variable, self.bar  #<---self.bar references class attribute
        self.bar = " Bar is now Baz"   #<---self.bar is now an instance attribute
        print self.variable, self.bar  

    def method(self, arg1, arg2):
        #This method has arguments.  You would call it like this:  instance.method(1, 2)
        print "in method (args):", arg1, arg2
        print "in method (attributes):", self.variable, self.bar


a = Foo() # this calls __init__ (indirectly), output:
                 # Foo bar
                 # Foo  Bar is now Baz
print a.variable # Foo
a.variable = "bar"
a.method(1, 2) # output:
               # in method (args): 1 2
               # in method (attributes): bar  Bar is now Baz
Foo.method(a, 1, 2) #<--- Same as a.method(1, 2).  This makes it a little more explicit what the argument "self" actually is.

class Bar(object):
    def __init__(self, arg):
        self.arg = arg
        self.Foo = Foo()

b = Bar(a)
b.arg.variable = "something"
print a.variable # something
print b.Foo.variable # Foo

Check out Effective Java, 2nd edition page 27. Item 7: Avoid finalizers

Finalizers are unpredictable, often dangerous, and generally unnecessary. never do anything time-critical in a finalizer. never depend on a finalizer to update critical persistent state.

To terminate a resource, use try-finally instead:

// try-finally block guarantees execution of termination method
Foo foo = new Foo(...);
try {
    // Do what must be done with foo
    ...
} finally {
    foo.terminate(); // Explicit termination method
}

If someone looking for calling a script with arguments

import subprocess

val = subprocess.check_call("./script.sh '%s'" % arg, shell=True)

Remember to convert the args to string before passing, using str(arg).

This can be used to pass as many arguments as desired:

subprocess.check_call("./script.ksh %s %s %s" % (arg1, str(arg2), arg3), shell=True)

Well, actually, React is not suitable for calling child methods from the parent. Some frameworks, like Cycle.js, allow easily access data both from parent and child, and react to it.

Also, there is a good chance you don't really need it. Consider calling it into existing component, it is much more independent solution. But sometimes you still need it, and then you have few choices:

• Pass method down, if it is a child (the easiest one, and it is one of the passed properties)
• add events library; in React ecosystem Flux approach is the most known, with Redux library. You separate all events into separated state and actions, and dispatch them from components
• if you need to use function from the child in a parent component, you can wrap in a third component, and clone parent with augmented props.

UPD: if you need to share some functionality which doesn't involve any state (like static functions in OOP), then there is no need to contain it inside components. Just declare it separately and invoke when need:

let counter = 0;
function handleInstantiate() {
   counter++;
}

constructor(props) {
   super(props);
   handleInstantiate();
}

If you google for javascript callback function example you will get Getting a better understanding of callback functions in JavaScript

This is how to do a callback function:

function f() {
    alert('f was called!');
}

function callFunction(func) {
    func();
}

callFunction(f);

Because the Method2 is static, all you have to do is call like this:

public class AllMethods
{
    public static void Method2()
    {
        // code here
    }
}

class Caller
{
    public static void Main(string[] args)
    {
        AllMethods.Method2();
    }
}

If they are in different namespaces you will also need to add the namespace of AllMethods to caller.cs in a using statement.

If you wanted to call an instance method (non-static), you'd need an instance of the class to call the method on. For example:

public class MyClass
{
    public void InstanceMethod() 
    { 
        // ...
    }
}

public static void Main(string[] args)
{
    var instance = new MyClass();
    instance.InstanceMethod();
}

Update

As of C# 6, you can now also achieve this with using static directive to call static methods somewhat more gracefully, for example:

// AllMethods.cs
namespace Some.Namespace
{
    public class AllMethods
    {
        public static void Method2()
        {
            // code here
        }
    }
}

// Caller.cs
using static Some.Namespace.AllMethods;

namespace Other.Namespace
{
    class Caller
    {
        public static void Main(string[] args)
        {
            Method2(); // No need to mention AllMethods here
        }
    }
}

As long as the macros in question are in the same workbook and you verify the names exist, you can call those macros from any other module by name, not by module.

So if in Module1 you had two macros Macro1 and Macro2 and in Module2 you had Macro3 and Macro 4, then in another macro you could call them all:

Sub MasterMacro()
    Call Macro1
    Call Macro2
    Call Macro3
    Call Macro4
End Sub

If you only have one input you can use the form tag.

<form ng-submit="myFunc()" ...>

If you have more than one input, or don't want to use the form tag, or want to attach the enter-key functionality to a specific field, you can inline it to a specific input as follows:

<input ng-keyup="$event.keyCode == 13 && myFunc()" ...>

For example 1 and 2 you need to create static methods:

public static string InstanceMethod() {return "Hello World";}

Then for example 3 you need an instance of your object to invoke the method:

object o = new object();
string s = o.InstanceMethod();

                close: function () { }
            });

That doesn't work because distToPoint is inside your class, so you need to prefix it with the classname if you want to refer to it, like this: classname.distToPoint(self, p). You shouldn't do it like that, though. A better way to do it is to refer to the method directly through the class instance (which is the first argument of a class method), like so: self.distToPoint(p).

I'll give a slightly advanced answer. In Python, functions are first-class objects. This means they can be "dynamically created, destroyed, passed to a function, returned as a value, and have all the rights as other variables in the programming language have."

Calling a function/class instance in Python means invoking the __call__ method of that object. For old-style classes, class instances are also callable but only if the object which creates them has a __call__ method. The same applies for new-style classes, except there is no notion of "instance" with new-style classes. Rather they are "types" and "objects".

As quoted from the Python 2 Data Model page, for function objects, class instances(old style classes), and class objects(new-style classes), "x(arg1, arg2, ...) is a shorthand for x.__call__(arg1, arg2, ...)".

Thus whenever you define a function with the shorthand def funcname(parameters): you are really just creating an object with a method __call__ and the shorthand for __call__ is to just name the instance and follow it with parentheses containing the arguments to the call. Because functions are first class objects in Python, they can be created on the fly with dynamic parameters (and thus accept dynamic arguments). This comes into handy with decorator functions/classes which you will read about later.

For now I suggest reading the Official Python Tutorial.

you can simply copy the servlet-api.jar and copy that jar files into lib folder, which is in WEB-INF. then just clean and built your project, your errors will be solved.

  **OR**

you can directly add jar files to library by using following steps.

1. Right click on project.
2. Go To Properties.
3. Go to Java Build Path.
4. Select Add Library option from tabs.
5. Add Jar Files
6. give path of your servlet-api.jar file.
7. Clean and build your project.

this might work for you...

$('.trhideclass1').hide();

<tr class="trhideclass1">
  <td>Label</td>
  <td>InputFile</td>

Apart from other answers, one could also use format()

print("a + b as integers: {}".format(c))

For example -

hours = 13
minutes = 32
print("Time elapsed - {} hours and {} minutes".format(hours, minutes))

will result in output - Time elapsed - 13 hours and 32 minutes

I don't know about targeting iOS as a whole, but to target iOS Safari specifically:

@supports (-webkit-touch-callout: none) {
   /* CSS specific to iOS devices */ 
}

@supports not (-webkit-touch-callout: none) {
   /* CSS for other than iOS devices */ 
}

Apparently as of iOS 13 -webkit-overflow-scrolling no longer responds to @supports, but -webkit-touch-callout still does. Of course that could change in the future...

//c++0x too
std::map<int,int> mapints;
std::vector<int> vints;
for(auto const& imap: mapints)
    vints.push_back(imap.first);

You could try adding a custom script, say myenv_vars.sh in /etc/profile.d.

cd /etc/profile.d
sudo touch myenv_vars.sh
sudo gedit myenv_vars.sh

Add this to the empty file, and save it.

export LD_LIBRARY_PATH=/usr/local/lib

Logout and login, LD_LIBRARY_PATH will have been set permanently.

Little Edit

Try adding

return new JavascriptResult() { Script = "alert('Successfully registered');" };

in place of

return RedirectToAction("Index");

A relatively newer (de)compression tool you might want to consider is zstandard. It does an excellent job of utilizing spare cores, and it has made some great trade-offs when it comes to compression ratio vs. (de)compression time. It is also highly tweak-able depending on your compression ratio needs.

You can use jQuery with AngularJS without any issue.

In fact, AngularJS uses jQuery lite in it, which is a great tool.

From FAQ

Does Angular use the jQuery library?

Yes, Angular can use jQuery if it's present in your app when the application is being bootstrapped. If jQuery is not present in your script path, Angular falls back to its own implementation of the subset of jQuery that we call jQLite.

However, don't try to use jQuery to modify the DOM in AngularJS controllers, do it in your directives.

Update:

Angular2 is released. Here is a great list of resource for starters

There are multiple ways to add the basic HTTP authentication to the RestTemplate.

1. For a single request

try {
    // request url
    String url = "https://jsonplaceholder.typicode.com/posts";

    // create auth credentials
    String authStr = "username:password";
    String base64Creds = Base64.getEncoder().encodeToString(authStr.getBytes());

    // create headers
    HttpHeaders headers = new HttpHeaders();
    headers.add("Authorization", "Basic " + base64Creds);

    // create request
    HttpEntity request = new HttpEntity(headers);

    // make a request
    ResponseEntity<String> response = new RestTemplate().exchange(url, HttpMethod.GET, request, String.class);

    // get JSON response
    String json = response.getBody();

} catch (Exception ex) {
    ex.printStackTrace();
}

If you are using Spring 5.1 or higher, it is no longer required to manually set the authorization header. Use headers.setBasicAuth() method instead:

// create headers
HttpHeaders headers = new HttpHeaders();
headers.setBasicAuth("username", "password");

2. For a group of requests

@Service
public class RestService {

    private final RestTemplate restTemplate;

    public RestService(RestTemplateBuilder restTemplateBuilder) {
        this.restTemplate = restTemplateBuilder
                .basicAuthentication("username", "password")
                .build();
    }

   // use `restTemplate` instance here
}

3. For each and every request

@Bean
RestOperations restTemplateBuilder(RestTemplateBuilder restTemplateBuilder) {
    return restTemplateBuilder.basicAuthentication("username", "password").build();
}

I hope it helps!

final long end = System.nanoTime();

System.out.println("Took: " + ((end - start) / 1000000) + "ms");

                    completion(path: destinationUrl.path!, error:error)
                }
            })
            task.resume()
        }
    }
}

Here's how to use it in your code:

let url = NSURL(string: "http://www.mywebsite.com/myfile.pdf") 
HttpDownloader.loadFileAsync(url, completion:{(path:String, error:NSError!) in
                println("pdf downloaded to: \(path)")
            })

You can use the static from() method from the LayoutInflater class:

 LayoutInflater li = LayoutInflater.from(context);

to implement this in algorithmic way, by not using any python inbuilt function . This can be implemented as

def find_pos(string,word):

    for i in range(len(string) - len(word)+1):
        if string[i:i+len(word)] == word:
            return i
    return 'Not Found'

string = "the dude is a cool dude"
word = 'dude1'
print(find_pos(string,word))
# output 4

If you want to always display some value after decimal for example "12.00" or "12.23" Then use just like below , it worked for me

FormatNumber("145.231000",2) Which will display 145.23

FormatNumber("145",2) Which will display 145.00

I'm not sure but:

• If you call the delete method with a non transient object, this means first fetched the object from the DB. So it is normal to see a select statement. Perhaps in the end you see 2 select + 1 delete?

• If you call the delete method with a transient object, then it is possible that you have a cascade="delete" or something similar which requires to retrieve first the object so that "nested actions" can be performed if it is required.

Edit: Calling delete() with a transient instance means doing something like that:

MyEntity entity = new MyEntity();
entity.setId(1234);
session.delete(entity);

This will delete the row with id 1234, even if the object is a simple pojo not retrieved by Hibernate, not present in its session cache, not managed at all by Hibernate.

If you have an entity association Hibernate probably have to fetch the full entity so that it knows if the delete should be cascaded to associated entities.

Sometimes another software can be holding this door and it can be the cause of this conflict, try change the door on the server.xml.

I had the same problem and I have resolved it by going through the following steps.

If you need to keep your changes

1. First you need to run git checkout master command to put you back to the master branch.
2. If you need to keep your changes just run git checkout -b changes and git checkout -B master changes

If you don't need your changes

1. To removes all untracked files from your branch run git clean -df.

2. Then you need to clear all unstaged changes within your repository. In order to do that you have to run git checkout --

3. Finally you have to put your branch back to the master branch by using git checkout master command.

The scaling on your example figure is a bit strange but you can force it by plotting the index of each x-value and then setting the ticks to the data points:

import matplotlib.pyplot as plt
x = [0.00001,0.001,0.01,0.1,0.5,1,5]
# create an index for each tick position
xi = list(range(len(x)))
y = [0.945,0.885,0.893,0.9,0.996,1.25,1.19]
plt.ylim(0.8,1.4)
# plot the index for the x-values
plt.plot(xi, y, marker='o', linestyle='--', color='r', label='Square') 
plt.xlabel('x')
plt.ylabel('y') 
plt.xticks(xi, x)
plt.title('compare')
plt.legend() 
plt.show()

to simulate RGBA and HSLA background in IE, you can use a gradient filter, with the same start and end color ( alpha channel is the first pair in the value of HEX )

background: rgba(255, 255, 255, 0.3); /* browsers */
filter: progid:DXImageTransform.Microsoft.gradient(GradientType=0,startColorstr='#4cffffff', endColorstr='#4cffffff'); /* IE */

Another thing to try is

Tools -> Options -> search for IIS -> tick Use the 64 bit version of IIS Express for web sites and projects.

You need to bind the modal hide call to the onclick event.

Assuming you are using jQuery you can do that with:

$('#closemodal').click(function() {
    $('#modalwindow').modal('hide');
});

Also make sure the click event is bound after the document has finished loading:

$(function() {
   // Place the above code inside this block
});
enter code here

Try like this...

select CONVERT (varchar(10), getdate(), 103) AS [DD/MM/YYYY]

For more info : http://www.sql-server-helper.com/tips/date-formats.aspx

If you want to want to treat 1,2 and 2,1 as the same pair, then this will give you the unique list on MS-SQL:

SELECT DISTINCT 
    CASE WHEN a > b THEN a ELSE b END as a,
    CASE WHEN a > b THEN b ELSE a END as b
FROM pairs

Inspired by @meszias answer above

I would choose the second as you don't have to do a copy of the memory and the Iterator works faster. So you save memory and time.

this worked for me in Sept 2015 - Hope this helps someone out there.

// 1
    var nav = self.navigationController?.navigationBar
    // 2 set the style 
    nav?.barStyle = UIBarStyle.Black
    nav?.tintColor = UIColor.yellowColor()
    // 3
    let imageView = UIImageView(frame: CGRect(x: 0, y: 0, width: 40, height: 40))
    imageView.contentMode = .ScaleAspectFit
    // 4
    let image = UIImage(named: "logo.png")
    imageView.image = image
    // 5
    navigationItem.titleView = imageView

The below code worked fine:

Run Keyword if    '${value1}' \ \ == \ \ '${cost1}' \ and \ \ '${value2}' \ \ == \ \ 'cost2'    LOG    HELLO

You can do it this way inside a program:

#include <sys/resource.h>

// core dumps may be disallowed by parent of this process; change that
struct rlimit core_limits;
core_limits.rlim_cur = core_limits.rlim_max = RLIM_INFINITY;
setrlimit(RLIMIT_CORE, &core_limits);

You can use the instanceof operator for this. From MDN:

The instanceof operator tests whether the prototype property of a constructor appears anywhere in the prototype chain of an object.

If you don't know what prototypes and prototype chains are I highly recommend looking it up. Also here is a JS (TS works similar in this respect) example which might clarify the concept:

    class Animal {_x000D_
        name;_x000D_
    _x000D_
        constructor(name) {_x000D_
            this.name = name;_x000D_
        }_x000D_
    }_x000D_
    _x000D_
    const animal = new Animal('fluffy');_x000D_
    _x000D_
    // true because Animal in on the prototype chain of animal_x000D_
    console.log(animal instanceof Animal); // true_x000D_
    // Proof that Animal is on the prototype chain_x000D_
    console.log(Object.getPrototypeOf(animal) === Animal.prototype); // true_x000D_
    _x000D_
    // true because Object in on the prototype chain of animal_x000D_
    console.log(animal instanceof Object); _x000D_
    // Proof that Object is on the prototype chain_x000D_
    console.log(Object.getPrototypeOf(Animal.prototype) === Object.prototype); // true_x000D_
    _x000D_
    console.log(animal instanceof Function); // false, Function not on prototype chain_x000D_
    _x000D_
    

The prototype chain in this example is:

animal > Animal.prototype > Object.prototype

The first part of your question is a duplicate of Why do I get a JsonReaderException with this code?, but the most relevant part from that (my) answer is this:

[A] JObject isn't the elementary base type of everything in JSON.net, but JToken is. So even though you could say,

object i = new int[0];

in C#, you can't say,

JObject i = JObject.Parse("[0, 0, 0]");

in JSON.net.

What you want is JArray.Parse, which will accept the array you're passing it (denoted by the opening [ in your API response). This is what the "StartArray" in the error message is telling you.

As for what happened when you used JArray, you're using arr instead of obj:

var rcvdData = JsonConvert.DeserializeObject<LocationData>(arr /* <-- Here */.ToString(), settings);

Swap that, and I believe it should work.

Although I'd be tempted to deserialize arr directly as an IEnumerable<LocationData>, which would save some code and effort of looping through the array. If you aren't going to use the parsed version separately, it's best to avoid it.

See my case on another similar question:

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

JSON.parse(stringifiedJSON);

In other words, what happened was the following:

JSON.parse("");

Try with :

If you want to use the catch() of the Observable you need to use Observable.throw() method before delegating the error response to a method

import { Injectable } from '@angular/core';_x000D_
import { Headers, Http, ResponseOptions} from '@angular/http';_x000D_
import { AuthHttp } from 'angular2-jwt';_x000D_
_x000D_
import { MEAT_API } from '../app.api';_x000D_
_x000D_
import { Observable } from 'rxjs/Observable';_x000D_
import 'rxjs/add/operator/map';_x000D_
import 'rxjs/add/operator/catch';_x000D_
_x000D_
@Injectable()_x000D_
export class CompareNfeService {_x000D_
_x000D_
_x000D_
  constructor(private http: AuthHttp) {}_x000D_
_x000D_
  envirArquivos(order): Observable < any > {_x000D_
    const headers = new Headers();_x000D_
    return this.http.post(`${MEAT_API}compare/arquivo`, order,_x000D_
        new ResponseOptions({_x000D_
          headers: headers_x000D_
        }))_x000D_
      .map(response => response.json())_x000D_
      .catch((e: any) => Observable.throw(this.errorHandler(e)));_x000D_
  }_x000D_
_x000D_
  errorHandler(error: any): void {_x000D_
    console.log(error)_x000D_
  }_x000D_
}

Using Observable.throw() worked for me

Starting in SQL Server 2017 the STRING_AGG function is available which simplifies the logic considerably:

select FieldA, string_agg(FieldB, '') as data
from yourtable
group by FieldA

See SQL Fiddle with Demo

In SQL Server you can use FOR XML PATH to get the result:

select distinct t1.FieldA,
  STUFF((SELECT distinct '' + t2.FieldB
         from yourtable t2
         where t1.FieldA = t2.FieldA
            FOR XML PATH(''), TYPE
            ).value('.', 'NVARCHAR(MAX)') 
        ,1,0,'') data
from yourtable t1;

Get "adbd insecure" from google play store, it helps give write access to custom roms that have it secured my the manufacturers.

Late to the party perhaps, but I wanted to share my take on this. I'm using a Builder pattern and allow conveniently chained append(more) calls, and allows mixing File and String. It can easily be extended to support working with Path objects as well, and furthermore handles the different path separators correctly on both Linux, Macintosh, etc.

public class Files  {
    public static class PathBuilder {
        private File file;

        private PathBuilder ( File root ) {
            file = root;
        }

        private PathBuilder ( String root ) {
            file = new File(root);
        }

        public PathBuilder append ( File more ) {
            file = new File(file, more.getPath()) );
            return this;
        }

        public PathBuilder append ( String more ) {
            file = new File(file, more);
            return this;
        }

        public File buildFile () {
            return file;
        }
    }

    public static PathBuilder buildPath ( File root ) {
        return new PathBuilder(root);
    }

    public static PathBuilder buildPath ( String root ) {
        return new PathBuilder(root);
    }
}

Example of usage:

File root = File.listRoots()[0];
String hello = "hello";
String world = "world";
String filename = "warez.lha"; 

File file = Files.buildPath(root).append(hello).append(world)
              .append(filename).buildFile();
String absolute = file.getAbsolutePath();

The resulting absolute will contain something like:

/hello/world/warez.lha

or maybe even:

A:\hello\world\warez.lha

This should do it. You were missing a ) and you only need """ not 4 of them. Also you don't need a elif at the end.

ans=True
while ans:
    print("""
    1.Add a Student
    2.Delete a Student
    3.Look Up Student Record
    4.Exit/Quit
    """)
    ans=raw_input("What would you like to do? ")
    if ans=="1":
      print("\nStudent Added")
    elif ans=="2":
      print("\n Student Deleted")
    elif ans=="3":
      print("\n Student Record Found")
    elif ans=="4":
      print("\n Goodbye") 
      ans = None
    else:
       print("\n Not Valid Choice Try again")

same as a normal modulo 3.14 % 6.28 = 3.14, just like 3.14%4 =3.14 3.14%2 = 1.14 (the remainder...)

An svg dynamic solution for any screen is the following:

<svg xmlns="http://www.w3.org/2000/svg" width="100%" height="100%" stroke-width="1" stroke="#000">
  <line x1="0" y1="0" x2="100%" y2="100%"/>
  <line x1="100%" y1="0" x2="0" y2="100%"/>
</svg>

And if you want to keep it in background use the position: absolute with top and left 0.

I did it this way:

<update id="updateSettings" parameterType="PushSettings">
    <foreach collection="settings" item="setting">
        UPDATE push_setting SET status = #{setting.status}
        WHERE type = #{setting.type} AND user_id = #{userId};
    </foreach>
</update>

where PushSettings is

public class PushSettings {

    private List<PushSetting> settings;
    private String userId;
}

it works fine

if (($num >= $lower_boundary) && ($num <= $upper_boundary)) {

You may want to adjust the comparison operators if you want the boundary values not to be valid.

Here is a simple and clean solution I created so I could inject it into multiple components.

ResizeService.ts

import { Injectable } from '@angular/core';
import { Subject } from 'rxjs';

@Injectable({
  providedIn: 'root'
})
export class ResizeService {

  constructor() {

    window.addEventListener('resize', (e) => {
      this.onResize.next();
    });

  }

  public onResize = new Subject();

}

In use:

constructor(
  private resizeService: ResizeService
) { 

  this.subscriptions.push(this.resizeService.onResize.subscribe(() => {
    // Do stuff
  }));

}

private subscriptions: Subscription[] = [];

Like you I also faced many problems implementing OCR in Android, but after much Googling I found the solution, and it surely is the best example of OCR.

Let me explain using step-by-step guidance.

First, download the source code from https://github.com/rmtheis/tess-two.

Import all three projects. After importing you will get an error. To solve the error you have to create a res folder in the tess-two project

First, just create res folder in tess-two by tess-two->RightClick->new Folder->Name it "res"

After doing this in all three project the error should be gone.

Now download the source code from https://github.com/rmtheis/android-ocr, here you will get best example.

Now you just need to import it into your workspace, but first you have to download android-ndk from this site:

http://developer.android.com/tools/sdk/ndk/index.html i have windows 7 - 32 bit PC so I have download http://dl.google.com/android/ndk/android-ndk-r9-windows-x86.zip this file

Now extract it suppose I have extract it into E:\Software\android-ndk-r9 so I will set this path on Environment Variable

Right Click on MyComputer->Property->Advance-System-Settings->Advance->Environment Variable-> find PATH on second below Box and set like path like below picture

done it

Now open cmd and go to on D:\Android Workspace\tess-two like below

If you have successfully set up environment variable of NDK then just type ndk-build just like above picture than enter you will not get any kind of error and all file will be compiled successfully:

Now download other source code also from https://github.com/rmtheis/tess-two , and extract and import it and give it name OCRTest, like in my PC which is in D:\Android Workspace\OCRTest

Import test-two in this and run OCRTest and run it; you will get the best example of OCR.

Just json.dumps will fix the problem

json.dumps function actually converts all the unicode literals to string literals and it will be easy for us to load the data either in json file or csv file.

sample code:

import json
EmployeeList =  [u'1001', u'Karick', u'14-12-2020', u'1$']
result_list = json.dumps(EmployeeList)
print result_list

output: ["1001", "Karick", "14-12-2020", "1$"]

Using some of the knowledge from this and a couple of other posts, I found the method that worked the best for me was to:

adb shell 'stty raw; screencap -p'

I have posted a very simple Python script on GitHub that essentially mirrors the screen of a device connected over ADB:

https://github.com/baitisj/android_screen_mirror

I managed to stop this behavior by adding the following to the HTML header. This works on mobile devices, as desktop browsers support zooming when using the mouse wheel. It's not a big deal on desktop browsers but it's important to take this into account.

<meta name="viewport" content="width=device-width, initial-scale=1.0, minimum-scale=1.0, maximum-scale=1.0, user-scalable=no" />

and the following rule to the CSS stylesheet

html {_x000D_
 -webkit-text-size-adjust: none;_x000D_
 touch-action: manipulation;_x000D_
}

Advanced Conventional Formatting [Update]

XMLSpectrum is an open source syntax-highlighter. Supporting XML - but with special features for XSLT 2.0, XSD 1.1 and XPath 2.0. I'm mentioning this here because it also has special formatting capabilities for XML: it vertically aligns attributes and their contents as well as elements - to enhance XML readability.

The output HTML is suitable for reviewing in a browser or if the XML needs further editing it can be copied and pasted into an XML editor of your choice

Because xmlspectrum.xsl uses its own XML text parser, all content such as entity references and CDATA sections are preserved - as in an editor.

Note on usage: this is just an XSLT 2.0 stylesheet so you would need to enclose the required command-line (samples provided) in a small script so you could automatically transform the XML source.

Virtual Formatting

XMLQuire is a free XML editor that has special formatting capabilities - it formats XML properly, including multi-line attributes, attribute-values, word-wrap indentation and even XML comments.

All XML indentation is done without inserting tabs or spaces, ensuring the integrity of the XML is maintained. For versions of Windows later than XP, no installation is needed, its just a 3MB .exe file.

If you need to print out the formatted XML there are special options within the print-preview, such as line-numbering that follows the indentation. If you need to copy the formatted XML to a word processor as rich text, that's available too.

[Disclosure: I maintain both XMLQuire and XMLSpectrum as 'home projects']

2 points in addition to all other good answers:

1:

what are the Grant Tables?

from dev.mysql.com

The MySQL system database includes several grant tables that contain information about user accounts and the privileges held by them.

clari?cation: in MySQL, there are some inbuilt databases , one of them is "mysql" , all the tables on "mysql" database have been called as grant tables

2:

note that if you perform:

UPDATE a_grant_table SET password=PASSWORD('1234') WHERE test_col = 'test_val';

and refresh phpMyAdmin , you'll realize that your password has been changed on that table but even now if you perform:

mysql -u someuser -p

your access will be denied by your new password until you perform :

FLUSH PRIVILEGES;

@A-312's solution may cause memory problems as it may create a huge array if /xampp/htdocs/WORK contains a lot of files and folders.

If you have PHP 7 then you can use Generators and optimize PHP's memory like this:

function getDirContents($dir) {
    $files = scandir($dir);
    foreach($files as $key => $value){

        $path = realpath($dir.DIRECTORY_SEPARATOR.$value);
        if(!is_dir($path)) {
            yield $path;

        } else if($value != "." && $value != "..") {
           yield from getDirContents($path);
           yield $path;
        }
    }
}

foreach(getDirContents('/xampp/htdocs/WORK') as $value) {
    echo $value."\n";
}

yield from

Trying to access an undefined variable will throw you a ReferenceError.

A solution to this is to use typeof:

if (typeof window === "undefined") {
  console.log("Oops, `window` is not defined")
}

or a try catch:

try { window } catch (err) {
  console.log("Oops, `window` is not defined")
}

While typeof window is probably the cleanest of the two, the try catch can still be useful in some cases.

The Microsoft Ajax Client Library makes it simple to implement OO in javascript. It supports inharitence, and interface implementation.

Should it be LIBRARY_PATH instead of LD_LIBRARY_PATH. gcc checks for LIBRARY_PATH which can be seen with -v option

To set up something simple that allows a Postgresql connection from the docker container to my localhost I used this in postgresql.conf:

listen_addresses = '*'

And added this pg_hba.conf:

host    all             all             172.17.0.0/16           password

Then do a restart. My client from the docker container (which was at 172.17.0.2) could then connect to Postgresql running on my localhost using host:password, database, username and password.

Yes. You can have a span within a span. Your problem stems from something else.

A few months ago I had the same problem and every library I found provides too much functionality and complexity for my final goal. So I end up developing my own library - HtmlFlow - that provides a very simple and intuitive API that allows me to write HTML in a fluent style. Check it here: https://github.com/fmcarvalho/HtmlFlow (it also supports dynamic binding to HTML elements)

Here is an example of binding the properties of a Task object into HTML elements. Consider a Task Java class with three properties: Title, Description and a Priority and then we can produce an HTML document for a Task object in the following way:

import htmlflow.HtmlView;

import model.Priority;
import model.Task;

import java.io.FileOutputStream;
import java.io.IOException;
import java.io.PrintStream;

public class App {

    private static HtmlView<Task> taskDetailsView(){
        HtmlView<Task> taskView = new HtmlView<>();
        taskView
                .head()
                .title("Task Details")
                .linkCss("https://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css");
        taskView
                .body().classAttr("container")
                .heading(1, "Task Details")
                .hr()
                .div()
                .text("Title: ").text(Task::getTitle)

                .br()
                .text("Priority: ").text(Task::getPriority);
        return taskView;
    }

    public static void main(String [] args) throws IOException{
        HtmlView<Task> taskView = taskDetailsView();
        Task task =  new Task("Special dinner", "Have dinner with someone!", Priority.Normal);

        try(PrintStream out = new PrintStream(new FileOutputStream("Task.html"))){
            taskView.setPrintStream(out).write(task);
            Desktop.getDesktop().browse(URI.create("Task.html"));
        }
    }
}

Make sure docker is running in your local machine. build command will work but its required running docker to get network data.

I think it will help.

There are lots of explanation of Jmeter Summary, I have been using this tool from quite some time for generating performance testing report with relevant data. The explanation available on below link is right from the field experience:

Jmeter:Understanding Summary Report

This is one of the most useful report generated by Jmeter to undertstand the load test result.

# Label: Name of HTTP sample request send to server

# Samples : This Captures the total number of samples pushed to server. Suppose you put a Loop Controller to run it 5 times this particular request and then 2 iteration(Called Loop Count in Thread Group)is set and load test is run for 100 users, then the count that will be displayed here .... 1*5*2 * 100 =1000. Total = total number of samples send to server during entire run.

# Average : It's an average response time for a particular http request. This response time is in millisecond, and an average for 5 loops in two iteration for 100 users. Total = Average of total average of samples, means add all averages for all samples and divide by number of samples

# Min : Minmum time spend by sample requests send for this label. The total equals to the minimum time across all samples.

# Max : Maximum tie spend by sample requests send for this label The total equals to the maxmimum time across all samples.

# Std. Dev. : Knowing the standard deviation of your data set tells you how densely the data points are clustered around the mean. The smaller the standard deviation, the more consistent the data. Standard deviation should be less than or equal to half of the average time for a label. If it is more than that, then it means that something is wrong. you need to figure out the problem and fix it. https://en.wikipedia.org/wiki/Standard_deviation Total is euqals to highest deviation across all samples.

# Error: Total percentage of erros found for a particular sample request. 0.0% shows that all requests completed successfully. Total equals to percentage of errors samples in all samples (Total Samples)

# Throughput: Hits/sec, or total number of request per unit of time(sec, mins, hr) send to server during test.

endTime = lastSampleStartTime + lastSampleLoadTime
startTime = firstSampleStartTime
converstion = unit time conversion value
Throughput = Numrequests / ((endTime - startTime)*conversion)

# KB/sec : Its mesuring throughput rate in Kilobytes per second.

# Avg. Bytes: Avegare of total bytes of data downloaded from server. Totals is average bytes across all samples.

It's been a while since I read it (so, I'm not sure how much of it is still relevant), but my recollection is that Joe Celko's SQL for Smarties book provides a lot of info on writing elegant, effective, and efficient queries.

When I develop, I have only three things in mind that never cause me any problems.

1. Import super classes
2. Import parent classes (when you have children and parents)
3. Import classes outside your project (like in frameworks and libraries)

For all other classes (subclasses and child classes in my project self), I declare them via forward-class.

If I understand you correctly, you want to compose a multipart request manually from an HTTP/REST console. The multipart format is simple; a brief introduction can be found in the HTML 4.01 spec. You need to come up with a boundary, which is a string not found in the content, let’s say HereGoes. You set request header Content-Type: multipart/form-data; boundary=HereGoes. Then this should be a valid request body:

--HereGoes
Content-Disposition: form-data; name="myJsonString"
Content-Type: application/json

{"foo": "bar"}
--HereGoes
Content-Disposition: form-data; name="photo"
Content-Type: image/jpeg
Content-Transfer-Encoding: base64

<...JPEG content in base64...>
--HereGoes--

There is an important detail:

set PATH="C:\linutils;C:\wingit\bin;%PATH%"

does not work, while

set PATH=C:\linutils;C:\wingit\bin;%PATH%

works. The difference is the quotes!

UPD also see the comment by venimus

See this blog post. If you call preventDefault on every touchstart then you should also have a CSS rule to disable touch scrolling like

.sortable-handler {
  touch-action: none;
}

You should checkout Junit-ext project. They have RunIf annotation that performs conditional tests, like:

@Test
@RunIf(DatabaseIsConnected.class)
public void calculateTotalSalary() {
    //your code there
}

class DatabaseIsConnected implements Checker {
   public boolean satisify() {
        return Database.connect() != null;
   }
}

[Code sample taken from their tutorial]

The new standard in Python is PEP 435, so an Enum class will be available in future versions of Python:

>>> from enum import Enum

However to begin using it now you can install the original library that motivated the PEP:

$ pip install flufl.enum

Then you can use it as per its online guide:

>>> from flufl.enum import Enum
>>> class Colors(Enum):
...     red = 1
...     green = 2
...     blue = 3
>>> for color in Colors: print color
Colors.red
Colors.green
Colors.blue

do not forget to do it with parse html. like:

$.ajax({
    url: url, 
    cache: false,
    success: function(response) {
        var parsed = $.parseHTML(response);
        result = $(parsed).find("#result");
    }
});

has to work :)

you can use flex display such as below code:

.example{_x000D_
  background-color:red;_x000D_
  height:90px;_x000D_
  width:90px;_x000D_
  display:flex;_x000D_
  align-items:center; /*for vertically center*/_x000D_
  justify-content:center; /*for horizontally center*/_x000D_
}

<div class="example">_x000D_
    <h6>Some text</h6>_x000D_
</div>

Here's other way of getting Zscore using custom function:

In [6]: import pandas as pd; import numpy as np

In [7]: np.random.seed(0) # Fixes the random seed

In [8]: df = pd.DataFrame(np.random.randn(5,3), columns=["randomA", "randomB","randomC"])

In [9]: df # watch output of dataframe
Out[9]:
    randomA   randomB   randomC
0  1.764052  0.400157  0.978738
1  2.240893  1.867558 -0.977278
2  0.950088 -0.151357 -0.103219
3  0.410599  0.144044  1.454274
4  0.761038  0.121675  0.443863

## Create custom function to compute Zscore 
In [10]: def z_score(df):
   ....:         df.columns = [x + "_zscore" for x in df.columns.tolist()]
   ....:         return ((df - df.mean())/df.std(ddof=0))
   ....:

## make sure you filter or select columns of interest before passing dataframe to function
In [11]: z_score(df) # compute Zscore
Out[11]:
   randomA_zscore  randomB_zscore  randomC_zscore
0        0.798350       -0.106335        0.731041

query runs a standard SQL statement and requires you to properly escape all data to avoid SQL Injections and other issues.

execute runs a prepared statement which allows you to bind parameters to avoid the need to escape or quote the parameters. execute will also perform better if you are repeating a query multiple times. Example of prepared statements:

$sth = $dbh->prepare('SELECT name, colour, calories FROM fruit
    WHERE calories < :calories AND colour = :colour');
$sth->bindParam(':calories', $calories);
$sth->bindParam(':colour', $colour);
$sth->execute();
// $calories or $color do not need to be escaped or quoted since the
//    data is separated from the query

Best practice is to stick with prepared statements and execute for increased security.

See also: Are PDO prepared statements sufficient to prevent SQL injection?

>>> import numpy as np
>>> A = np.array([[1,2,3,4],[5,6,7,8]])

>>> A
array([[1, 2, 3, 4],
    [5, 6, 7, 8]])

>>> A[:,2] # returns the third columm
array([3, 7])

See also: "numpy.arange" and "reshape" to allocate memory

Example: (Allocating a array with shaping of matrix (3x4))

nrows = 3
ncols = 4
my_array = numpy.arange(nrows*ncols, dtype='double')
my_array = my_array.reshape(nrows, ncols)

There are multiple ways to do this:

Handle orientation changes by yourself

Another alternative is to handle the orientation changes by yourself. But this is not considered a good practice.

Add this to your manifest file.

android:configChanges="keyboardHidden|orientation"

for Android 3.2 and later:

android:configChanges="keyboardHidden|orientation|screenSize"

@Override
public void onConfigurationChanged(Configuration config) {
    super.onConfigurationChanged(config);

if (newConfig.orientation == Configuration.ORIENTATION_PORTRAIT) {
        //Handle rotation from landscape to portarit mode here
    } else if (newConfig.orientation == Configuration.ORIENTATION_LANDSCAPE){
        //Handle rotation from portrait to landscape mode here
    }
}

OR Restrict rotation

You can also confine your activity to portrait or landscape mode to avoid rotation.

Add this to the activity tag in your manifest file:

android:screenOrientation="portrait"

Or implement this programmatically in your activity:

@Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setRequestedOrientation(ActivityInfo.SCREEN_ORIENTATION_PORTRAIT);
}

OR Save Activity State

You can save the activity state in onSaveInstanceState.

@Override
public void onSaveInstanceState(Bundle outState) {
    /*Save your data to be restored here
    Example : outState.putLong("time_state", time); , time is a long variable*/
    super.onSaveInstanceState(outState);
}

and then use the bundle to restore the state.

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    if(savedInstanceState!= null){
       /*When rotation occurs
        Example : time = savedInstanceState.getLong("time_state", 0); */
    } else {
      //When onCreate is called for the first time
    }
}

The > and < are transitive properties, so if a > b and b > c, then a > c. So you can

int a=10, b=6, c=4, d=21, e=4;

int maxNum = a;
int maxNum = max(b, maxNum);
int maxNum = max(c, maxNum);
int maxNum = max(d, maxNum);
int maxNum = max(e, maxNum);

There are many options to change the font size in the Visual studio code(version:1.36.1), Editor

Option 1:

Go To: File > Preferences > Settings > select User tab > Text Editor > Font > Font Size

Font Size: Change font size in pixels as per your requirement

Option 2:

Press Ctrl + P

Search: settings.json, Open file and add this line in settings.json file:

{
    "editor.fontSize": 20
}

Note: Save file after changes

Option 3:

Press Ctrl + Shift + P

Search: Editor Font Zoom In

• Just click on it, your font size will be increased

Search: Editor Font Zoom Out

• Just click on it, your font size will be decreased

Supporting Ruivo's answer, yes you have to declare method as "public" to be able to use in Android's XML onclick - I am developing an app targeting from API Level 8 (minSdk...) to 16 (targetSdk...).

I was declaring my method as private and it caused error, just declaring it as public works great.

I believe you are getting an empty array because PHP is expecting the posted data to be in a Querystring format (key=value&key1=value1).

Try changing your curl request to:

curl -i -X POST -d 'json={"screencast":{"subject":"tools"}}'  \
      http://localhost:3570/index.php/trainingServer/screencast.json

and see if that helps any.

The explanation for how it works:

JUnit wraps your test method in a Statement object so statement and Execute() runs your test. Then instead of calling statement.Execute() directly to run your test, JUnit passes the Statement to a TestRule with the @Rule annotation. The TestRule's "apply" function returns a new Statement given the Statement with your test. The new Statement's Execute() method can call the test Statement's execute method (or not, or call it multiple times), and do whatever it wants before and after.

Now, JUnit has a new Statement that does more than just run the test, and it can again pass that to any more rules before finally calling Execute.

Also good analogy can be with C# if you familiar with. Basically C# Select similar to java map and C# SelectMany java flatMap. Same applies to Kotlin for collections.

Try using this code for v3:

gMap = new google.maps.Map(document.getElementById('map')); 
gMap.setZoom(13);      // This will trigger a zoom_changed on the map
gMap.setCenter(new google.maps.LatLng(37.4419, -122.1419));
gMap.setMapTypeId(google.maps.MapTypeId.ROADMAP);

$final_array = array_combine($a, $a);

Reference: http://php.net/array-combine

P.S. Be careful with source array containing duplicated keys like the following:

$a = ['one','two','one'];

Note the duplicated one element.

For me the issue wasn't six but rst2pdf itself. head -1 $(which rst2pdf) (3.8) didn't match python3 --version (3.9). My solution:

pip3 install rst2pdf

I faced a problem that I had to use a timer, but I had to display them in 2 component same time, same screen. I created the timerObservable in a service. I subscribed to the timer in both component, and what happened? It won't be synched, cause new subscription always creates its own stream.

What I would like to say, is that if you plan to use one timer at several places, always put .publishReplay(1).refCount() at the end of the Observer, cause it will publish the same stream out of it every time.

Example:

this.startDateTimer = Observable.combineLatest(this.timer, this.startDate$, (localTimer, startDate) => {
  return this.calculateTime(startDate);
}).publishReplay(1).refCount();

based on this link , the correct answer (which i've tested myself) is:

put this code in the constructor or the onCreate() method of the dialog:

getWindow().setLayout(WindowManager.LayoutParams.MATCH_PARENT,
                WindowManager.LayoutParams.MATCH_PARENT);

in addition , set the style of the dialog to :

<style name="full_screen_dialog">
    <item name="android:windowFrame">@null</item>
    <item name="android:windowIsFloating">true</item>
    <item name="android:windowContentOverlay">@null</item>
    <item name="android:windowAnimationStyle">@android:style/Animation.Dialog</item>
    <item name="android:windowSoftInputMode">stateUnspecified|adjustPan</item>
</style>

this could be achieved via the constructor , for example :

public FullScreenDialog(Context context)
{
  super(context, R.style.full_screen_dialog);
  ...

EDIT: an alternative to all of the above would be to set the style to android.R.style.ThemeOverlay and that's it.

in this case, I use space for APP_NAME key in .env file.

and have below error :

The environment file is invalid!
Failed to parse dotenv file due to unexpected whitespace. Failed at [my name].
Script @php artisan package:discover handling the post-autoload-dump event returned with error code 1

Don't use space in APP_NAME key !!

Line width in ggplot2 can be changed with argument size= in geom_line().

#sample data
df<-data.frame(x=rnorm(100),y=rnorm(100))
ggplot(df,aes(x=x,y=y))+geom_line(size=2)

One way, provide --user flag as part of curl, as follows:

curl --user username:password http://example.com

Another way is to get Base64 encoded token of "username:password" from any online website like - https://www.base64encode.org/ and pass it as Authorization header of curl as follows:

curl -i -H 'Authorization:Basic dXNlcm5hbWU6cGFzc3dvcmQ=' http://localhost:8080/

Here, dXNlcm5hbWU6cGFzc3dvcmQ= is Base64 encoded token of username:password.

You can use the new URL for Google Maps: https://www.google.com/maps/@39.774769,-74.86084,18z equivalent to http://maps.google.com/?ll=39.774769,-74.86084.

39.774769 is the latitude and -74.86084 is longitude and 18z is 18 zoom level.

In my case the hosting had a whitelist for remote connection to MySql. Try to add your IP to whitelist in hosting admin panel.

The simplest way to create a manifest is:

Project Properties -> Security -> Click "enable ClickOnce security settings" 
(it will generate default manifest in your project Properties) -> then Click 
it again in order to uncheck that Checkbox -> open your app.maifest and edit 
it as you wish.

Try this one:

echo "$(ps -ceo pid=,comm= | awk '/firefox/ { print $1; exit }')"

The ps command produces output like this, with the PID in the first column and the executable name (only) in the second column:

bookworm% ps -ceo pid=,comm=
    1 launchd
   10 kextd
   11 UserEventAgent
   12 mDNSResponder
   13 opendirectoryd
   14 notifyd
   15 configd

...which awk processes, printing the first column (pid) and exiting after the first match.

Open your windows search bar, and search for the keyword Tomcat. If a shortcut file is found instead, you can open the source file location of the shortcut by right-clicking the shortcut file and selecting the Properties.

Just assign it to the .columns attribute:

>>> df = pd.DataFrame({'$a':[1,2], '$b': [10,20]})
>>> df
   $a  $b
0   1  10
1   2  20

>>> df.columns = ['a', 'b']
>>> df
   a   b
0  1  10
1  2  20

Run dos2unix or similar utility on it to remove the carriage returns (^M).

This message indicates that your file has dos-style lineendings:

-bash: /backup/backup.sh: /bin/bash^M: bad interpreter: No such file or directory 

Utilities like dos2unix will fix it:

 dos2unix <backup.bash >improved-backup.sh 

Or, if no such utility is installed, you can accomplish the same thing with translate:

tr -d "\015\032" <backup.bash >improved-backup.sh 

As for how those characters got there in the first place, @MadPhysicist had some good comments.

You can use a form to do a POST to the same URL.

 <form  method="POST" name="refresh" id="refresh">
 <input type="submit" value="Refresh" />
 </form>

This gives you a button that refreshes the current page. It is a bit annoying because if the user presses the browser refresh button, they will get a do you want to resubmit the form message.

When you use df.apply(), each row of your DataFrame will be passed to your lambda function as a pandas Series. The frame's columns will then be the index of the series and you can access values using series[label].

So this should work:

df['D'] = (df.apply(lambda x: myfunc(x[colNames[0]], x[colNames[1]]), axis=1)) 

I'm not sure what the query syntax is. But here is the expanded LINQ expression example.

var query = someList.Select(x => { x.SomeProp = "foo"; return x; })

What this does is use an anonymous method vs and expression. This allows you to use several statements in one lambda. So you can combine the two operations of setting the property and returning the object into this somewhat succinct method.

Using Guava you can write more elegantly CharMatcher.is('\"').trimFrom(mystring);

This is an issue with the jdbc Driver version. I had this issue when I was using mysql-connector-java-commercial-5.0.3-bin.jar but when I changed to a later driver version mysql-connector-java-5.1.22.jar, the issue was fixed.

I'm not sure whether it is a new feature in later versions of matplotlib, but at least for 1.3.1, this is simply:

plt.title(figure_title, y=1.08)

This also works for plt.suptitle(), but not (yet) for plt.xlabel(), etc.

I found the following codes work perfectly for the job.

fig = plt.figure(figsize=[6,6])
ax = fig.add_subplot(111)
ax.imshow(data)
ax.axes.get_xaxis().set_visible(False)
ax.axes.get_yaxis().set_visible(False)
ax.set_frame_on(False)
plt.savefig('data.png', dpi=400, bbox_inches='tight',pad_inches=0)

@DSM's answer is perfectly fine in almost any normal scenario. But if you're the type of programmer who wants to go a little deeper than the surface level, you might be interested to know that it is a little faster to call numpy functions on the underlying .to_numpy() (or .values for <0.24) array instead of directly calling the (cythonized) functions defined on the DataFrame/Series objects.

For example, you can use ndarray.max() along the first axis.

# Data borrowed from @DSM's post.
df = pd.DataFrame({"A": [1,2,3], "B": [-2, 8, 1]})
df
   A  B
0  1 -2
1  2  8
2  3  1

df['C'] = df[['A', 'B']].values.max(1)
# Or, assuming "A" and "B" are the only columns, 
# df['C'] = df.values.max(1) 
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3 

If your data has NaNs, you will need numpy.nanmax:

df['C'] = np.nanmax(df.values, axis=1)
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3 

You can also use numpy.maximum.reduce. numpy.maximum is a ufunc (Universal Function), and every ufunc has a reduce:

df['C'] = np.maximum.reduce(df['A', 'B']].values, axis=1)
# df['C'] = np.maximum.reduce(df[['A', 'B']], axis=1)
# df['C'] = np.maximum.reduce(df, axis=1)
df

   A  B  C
0  1 -2  1
1  2  8  8
2  3  1  3

np.maximum.reduce and np.max appear to be more or less the same (for most normal sized DataFrames)—and happen to be a shade faster than DataFrame.max. I imagine this difference roughly remains constant, and is due to internal overhead (indexing alignment, handling NaNs, etc).

The graph was generated using perfplot. Benchmarking code, for reference:

import pandas as pd
import perfplot

np.random.seed(0)
df_ = pd.DataFrame(np.random.randn(5, 1000))

perfplot.show(
    setup=lambda n: pd.concat([df_] * n, ignore_index=True),
    kernels=[
        lambda df: df.assign(new=df.max(axis=1)),
        lambda df: df.assign(new=df.values.max(1)),
        lambda df: df.assign(new=np.nanmax(df.values, axis=1)),
        lambda df: df.assign(new=np.maximum.reduce(df.values, axis=1)),
    ],
    labels=['df.max', 'np.max', 'np.maximum.reduce', 'np.nanmax'],
    n_range=[2**k for k in range(0, 15)],
    xlabel='N (* len(df))',
    logx=True,
    logy=True)

If you get the same value for both property and attribute, but still sees it different on the HTML try this to get the HTML one:

$('#inputID').context.defaultValue;

In python 2.7 here is how you do it

mantra = 'Always look on the bright side of life'
for c in mantra: print c,

#output
A l w a y s   l o o k   o n   t h e   b r i g h t   s i d e   o f   l i f e

In python 3.x

myjob= 'hacker'
for c in myjob: print (c, end=' ')
#output 
h a c k e r 

I used the advice of Kevin Jones above with the following --skip-networking change for slightly better security:

sudo systemctl set-environment MYSQLD_OPTS="--skip-grant-tables --skip-networking"

[user@machine ~]$ mysql -u root

Then when attempting to reset the password I received an error, but googling elsewhere suggested I could simply forge ahead. The following worked:

mysql> select user(), current_user();
+--------+-----------------------------------+
| user() | current_user()                    |
+--------+-----------------------------------+
| root@  | skip-grants user@skip-grants host |
+--------+-----------------------------------+
1 row in set (0.00 sec)

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'sup3rPw#'
ERROR 1290 (HY000): The MySQL server is running with the --skip-grant-tables option so it cannot execute this statement
mysql> FLUSH PRIVILEGES;
Query OK, 0 rows affected (0.02 sec)

mysql> ALTER USER 'root'@'localhost' IDENTIFIED BY 'sup3rPw#'
Query OK, 0 rows affected (0.08 sec)

mysql> exit
Bye
[user@machine ~]$ systemctl stop mysqld
[user@machine ~]$ sudo systemctl unset-environment MYSQLD_OPTS
[user@machine ~]$ systemctl start mysqld

At that point I was able to log in.

Both are models of an object that you have some means of controlling inputs and observing outputs. With an emulator, you want the output to be exactly what the object you are emulating would produce. With a simulator, you want certain properties of your output to be similar to what the object would produce.

Let me give an example -- suppose you want to do some system testing to see how adding a new sensor (like a thermometer) to a system would affect the system. You know that the thermometer sends a message 8 time a second containing its measurement.

Simulation -- if you do not have the thermometer yet, but you want to test that this message rate will not overload you system, you can simulate the sensor by attaching a unit that sends a random number 8 times a second. You can run any test that does not rely on the actual value the sensor sends.

Emulation -- suppose you have a very expensive thermometer that measures to 0.001 C, and you want to see if you can get by with a cheaper thermometer that only measures to the nearest 0.5 C. You can emulate the cheaper thermometer using an expensive thermometer by rounding the reading to the nearest 0.5 C and running tests that rely on the temperature values.

The downside of using docker exec is that it requires a running container, so docker inspect -f might be handy if you're unsure a container is running.

Example #1. Output a list of space-separated environment variables in the specified container:

docker inspect -f \
   '{{range $index, $value := .Config.Env}}{{$value}} {{end}}' container_name

the output will look like this:

ENV_VAR1=value1 ENV_VAR2=value2 ENV_VAR3=value3

Example #2. Output each env var on new line and grep the needed items, for example, the mysql container's settings could be retrieved like this:

docker inspect -f \
    '{{range $index, $value := .Config.Env}}{{println $value}}{{end}}' \
    container_name | grep MYSQL_

will output:

MYSQL_PASSWORD=secret
MYSQL_ROOT_PASSWORD=supersecret
MYSQL_USER=demo
MYSQL_DATABASE=demodb
MYSQL_MAJOR=5.5
MYSQL_VERSION=5.5.52

Example #3. Let's modify the example above to get a bash friendly output which can be directly used in your scripts:

docker inspect -f \
   '{{range $index, $value := .Config.Env}}export {{$value}}{{println}}{{end}}' \
   container_name | grep MYSQL

will output:

export MYSQL_PASSWORD=secret
export MYSQL_ROOT_PASSWORD=supersecret
export MYSQL_USER=demo
export MYSQL_DATABASE=demodb
export MYSQL_MAJOR=5.5
export MYSQL_VERSION=5.5.52

If you want to dive deeper, then go to Go’s text/template package documentation with all the details of the format.

You just use the method

public Object put(Object key, Object value)

if the key was already present in the Map then the previous value is returned.

If you have installed ToroiseGIT then just select "Revert..." menu item for parent folder popup-menu.

If you pass the JSON in your post to json_decode, it will fail. Valid JSON strings have quoted keys:

json_decode('{foo:"bar"}');         // this fails
json_decode('{"foo":"bar"}', true); // returns array("foo" => "bar")
json_decode('{"foo":"bar"}');       // returns an object, not an array.

for windows use & in between command also. Like,

  "scripts": {
    "start": "SET NODE_ENV=development & nodemon app/app.js",
  }

What this means

Your upstream—the remote you call origin—no longer has, or maybe never had (it's impossible to tell from this information alone) a branch named feature/Sprint4/ABC-123-Branch. There's one particularly common reason for that: someone (probably not you, or you'd remember) deleted the branch in that other Git repository.

What to do

This depends on what you want. See the discussion section below. You can:

• create or re-create the branch on the remote, or
• delete your local branch, or
• anything else you can think of.

Discussion

You must be running git pull (if you were running git merge you would get a different error message, or no error message at all).

When you run git fetch, your Git contacts another Git, based on the url line in under the [remote "origin"] section of your configuration. That Git runs a command (upload-pack) that, among other things, sends your Git a list of all branches. You can use git ls-remote to see how this works (try it, it is educational). Here is a snippet of what I get when running this on a Git repository for git itself:

$ git ls-remote origin
From [url]
bbc61680168542cf6fd3ae637bde395c73b76f0f    HEAD
60115f54bda3a127ed3cc8ffc6ab6c771cbceb1b    refs/heads/maint
bbc61680168542cf6fd3ae637bde395c73b76f0f    refs/heads/master
5ace31314f460db9aef2f1e2e1bd58016b1541f1    refs/heads/next
9e085c5399f8c1883cc8cdf175b107a4959d8fa6    refs/heads/pu
dd9985bd6dca5602cb461c4b4987466fa2f31638    refs/heads/todo
[snip]

The refs/heads/ entries list all of the branches that exist on the remote,¹ along with the corresponding commit IDs (for refs/tags/ entries the IDs may point to tag objects rather than commits).

Your Git takes each of these branch names and changes it according to the fetch line(s) in that same remote section. In this case, your Git replaces refs/heads/master with refs/remotes/origin/master, for instance. Your Git does this with every branch name that comes across.

It also records the original names in the special file FETCH_HEAD (you can see this file if you peek into your own .git directory). This file saves the fetched names and IDs.

The git pull command is meant as a convenience short cut: it runs git fetch on the appropriate remote, and then git merge (or, if so instructed, git rebase) with whatever arguments are needed to merge (or rebase) as directed by the [branch ...] section. In this case, your [branch "feature/Sprint4/ABC-123-Branch"] section says to fetch from origin, then merge with whatever ID was found under the name refs/heads/feature/Sprint4/ABC-123-Branch.

Since nothing was found under that name, git pull complains and stops.

If you ran this as two separate steps, git fetch and then git merge (or git rebase), your Git would look at your cached remotes/origin/ remote-tracking branches to see what to merge with or rebase onto. If there was such a branch at one time, you may still have the remote-tracking branch. In this case you would not get an error message. If there was never such a branch, or if you have run git fetch with --prune (which removes dead remote-tracking branches), so that you have no corresponding remote-tracking branch, you would get a complaint, but it would refer to origin/feature/Sprint4/ABC-123-Branch instead.

In either case, we can conclude that feature/Sprint4/ABC-123-Branch does not exist now on the remote named origin.

It probably did exist at one time, and you probably created your local branch from the remote-tracking branch. If so, you probably still have the remote-tracking branch. You might investigate to see who removed the branch from the remote, and why, or you might just push something to re-create it, or delete your remote-tracking branch and/or your local branch.

¹Well, all that it is going to admit to, at least. But unless they have specifically hidden some refs, the list includes everything.

Edit, Jul 2020: There's a new fetch protocol that can avoid listing everything, and only list names that your Git says it's looking for. This can help with repositories that have huge numbers of branches and/or tags. However, if your Git is interested in all possible names, you'll still get all the names here.

just use:

$ sudo mysql

without the "-u root" parameter.

Use a table variable if for a very small quantity of data (thousands of bytes)

Use a temporary table for a lot of data

Another way to think about it: if you think you might benefit from an index, automated statistics, or any SQL optimizer goodness, then your data set is probably too large for a table variable.

In my example, I just wanted to put about 20 rows into a format and modify them as a group, before using them to UPDATE / INSERT a permanent table. So a table variable is perfect.

But I am also running SQL to back-fill thousands of rows at a time, and I can definitely say that the temporary tables perform much better than table variables.

This is not unlike how CTE's are a concern for a similar size reason - if the data in the CTE is very small, I find a CTE performs as good as or better than what the optimizer comes up with, but if it is quite large then it hurts you bad.

My understanding is mostly based on http://www.developerfusion.com/article/84397/table-variables-v-temporary-tables-in-sql-server/, which has a lot more detail.

Streams are EventEmitters so you can listen to certain events. As you said there is a finish event for request (previously end).

 var stream = request(...).pipe(...);
 stream.on('finish', function () { ... });

For more information about which events are available you can check the stream documentation page.

Yes, you can. Based on knowledge from colleagues here and researching on web, here you have the best solution for styling a checkbox without any third-party plugin:

input[type='checkbox']{
  width: 14px !important;
  height: 14px !important;
  margin: 5px;
  -webkit-appearance: none;
  -moz-appearance: none;
  -o-appearance: none;
  appearance: none;
  outline: 1px solid gray;
  box-shadow: none;
  font-size: 0.8em;
  text-align: center;
  line-height: 1em;
  background: red;
}

input[type='checkbox']:checked:after {
  content: '?';
  color: white;
}

<input type='checkbox'>

Since you can also input numbers as well as fixed type strings, the answer should actually be:

function isBlank(value) {
  return $.trim(value);
}

The same as David's, but without attr()

$('<input>', {
    type: 'hidden',
    id: 'foo',
    name: 'foo',
    value: 'bar'
}).appendTo('form');

From Save (Not Permitted) Dialog Box on MSDN :

The Save (Not Permitted) dialog box warns you that saving changes is not permitted because the changes you have made require the listed tables to be dropped and re-created.

The following actions might require a table to be re-created:

• Adding a new column to the middle of the table
• Dropping a column
• Changing column nullability
• Changing the order of the columns
• Changing the data type of a column <<<<

To change this option, on the Tools menu, click Options, expand Designers, and then click Table and Database Designers. Select or clear the Prevent saving changes that require the table to be re-created check box.

See Also Colt Kwong Blog Entry:
Saving changes is not permitted in SQL 2008 Management Studio

Simply copy the file, add and commit it:

cp dir1/A.txt dir2/A.txt
git add dir2/A.txt
git commit -m "Duplicated file from dir1/ to dir2/"

Then the following commands will show the full pre-copy history:

git log --follow dir2/A.txt

To see inherited line-by-line annotations from the original file use this:

git blame -C -C -C dir2/A.txt

Git does not track copies at commit-time, instead it detects them when inspecting history with e.g. git blame and git log.

Most of this information comes from the answers here: Record file copy operation with Git

As answered by others, there's a limit on url size with get, and files can be submitted with post only.

I'd like to add that one can add things to a database with a get and perform actions with a post. When a script receives a post or a get, it can do whatever the author wants it to do. I believe the lack of understanding comes from the wording the book chose or how you read it.

A script author should use posts to change the database and use get only for retrieval of information.

Scripting languages provided many means with which to access the request. For example, PHP allows the use of $_REQUEST to retrieve either a post or a get. One should avoid this in favor of the more specific $_GET or $_POST.

In web programming, there's a lot more room for interpretation. There's what one should and what one can do, but which one is better is often up for debate. Luckily, in this case, there is no ambiguity. You should use posts to change data, and you should use get to retrieve information.

By the looks of it, apart from starting another process, there doesn't seem to be any way of handling a StackOverflowException. Before anyone else asks, I tried using AppDomain, but that didn't work:

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

namespace StackOverflowExceptionAppDomainTest
{
    class Program
    {
        static void recrusiveAlgorithm()
        {
            recrusiveAlgorithm();
        }
        static void Main(string[] args)
        {
            if(args.Length>0&&args[0]=="--child")
            {
                recrusiveAlgorithm();
            }
            else
            {
                var domain = AppDomain.CreateDomain("Child domain to test StackOverflowException in.");
                domain.ExecuteAssembly(Assembly.GetEntryAssembly().CodeBase, new[] { "--child" });
                domain.UnhandledException += (object sender, UnhandledExceptionEventArgs e) =>
                {
                    Console.WriteLine("Detected unhandled exception: " + e.ExceptionObject.ToString());
                };
                while (true)
                {
                    Console.WriteLine("*");
                    Thread.Sleep(1000);
                }
            }
        }
    }
}

If you do end up using the separate-process solution, however, I would recommend using Process.Exited and Process.StandardOutput and handle the errors yourself, to give your users a better experience.

Linux: with unexpand (and expand)

Here is a very good solution: https://stackoverflow.com/a/11094620/1115187, mostly because it uses *nix-utilities:

1. unexpand — spaces -> tabs
2. expand — tabs -> spaces

Linux: custom script

^{My original answer}

Bash snippet for replacing 4-spaces indentation (there are two {4} in script) with tabs in all .py files in the ./app folder (recursively):

find ./app -iname '*.py' -type f \
    -exec awk -i inplace \
    '{ match($0, /^(( {4})*)(.*?)$/, arr); gsub(/ {4}/, "\t", arr[1]) }; { print arr[1] arr[3] }' {} \; 

It doesn't modify 4-spaces in the middle or at the end.

JRE is a Run-Time Environment for running Java stuffs on your machine. What Eclipse needs is JDK as a Development Kit.

Install the latest JDK (and not JRE) from http://www.oracle.com/technetwork/pt/java/javase/downloads/jdk8-downloads-2133151.html and you should be good on Mac!

I know this question has a lot of answers, but from what I saw nobody approaches the answer the way I would solve this.

CSS uses width (Media Queries) to determine which styles applied to the web document baseed on width. Why not use width in the JavaScript?

For instance in Bootstrap's (Mobile First) Media Queries, there exist 4 snap/break points:

• Extra Small Devices are 768 pixels and under.
• Small Devices range from 768 to 991 pixels.
• Medium Devices range from 992 to 1199 pixels.
• Large Devices are 1200 pixels and up.

We can use this to also solve our JavaScript issue as well.

First we will create a function that gets the window size and returns a value that allows us to see what size device is viewing our application:

var getBrowserWidth = function(){
    if(window.innerWidth < 768){
        // Extra Small Device
        return "xs";
    } else if(window.innerWidth < 991){
        // Small Device
        return "sm"
    } else if(window.innerWidth < 1199){
        // Medium Device
        return "md"
    } else {
        // Large Device
        return "lg"
    }
};

Now that we have the function set up, we can call it ans store the value:

var device = getBrowserWidth();

Your question was

I would like to run a different script if the browser is on a handheld device.

Now that we have the device information all that is left is an if statement:

if(device === "xs"){
  // Enter your script for handheld devices here 
}

Here is an example on CodePen: http://codepen.io/jacob-king/pen/jWEeWG

Was just trying to work this out myself, and the solution I came up with was:

<meta name="viewport" content="initial-scale = 1.0,maximum-scale = 1.0" />

This seems to lock the device into 1.0 scale regardless of it's orientation. As a side effect, it does however completely disable user scaling (pinch zooming, etc).

What worked for me was restarting IIS

You can do

[5, 10].min

or

[4, 7].max

They come from the Enumerable module, so anything that includes Enumerable will have those methods available.

v2.4 introduces own Array#min and Array#max, which are way faster than Enumerable's methods because they skip calling #each.

@nicholasklick mentions another option, Enumerable#minmax, but this time returning an array of [min, max].

[4, 5, 7, 10].minmax
=> [4, 10]

Carbon has a bunch of comparison functions with mnemonic names:

• equalTo()
• notEqualTo()
• greaterThan()
• greaterThanOrEqualTo()
• lessThan()
• lessThanOrEqualTo()

Usage:

 if($model->edited_at->greaterThan($model->created_at)){
     // edited at is newer than created at
 }

Valid for nesbot/carbon 1.36.2

if you are not sure what Carbon version you are on, run this

@RequestParam makes Spring to map request parameters from the GET/POST request to your method argument.

GET Request

http://testwebaddress.com/getInformation.do?city=Sydney&country=Australia

public String getCountryFactors(@RequestParam(value = "city") String city, 
                    @RequestParam(value = "country") String country){ }

POST Request

@RequestBody makes Spring to map entire request to a model class and from there you can retrieve or set values from its getter and setter methods. Check below.

http://testwebaddress.com/getInformation.do

You have JSON data as such coming from the front end and hits your controller class

{
   "city": "Sydney",
   "country": "Australia"
}

Java Code - backend (@RequestBody)

public String getCountryFactors(@RequestBody Country countryFacts)
    {
        countryFacts.getCity();
        countryFacts.getCountry();
    }


public class Country {

    private String city;
    private String country;

    public String getCity() {
        return city;
    }

    public void setCity(String city) {
        this.city = city;
    }

    public String getCountry() {
        return country;
    }

    public void setCountry(String country) {
        this.country = country;
    }
}

Two possible answers:

1- You did not include spring-beans and spring-context jars in your lib. If you are using maven (which will help a lot) those two lines will be enough

<dependency>
 <groupId>org.springframework</groupId>
  <artifactId>spring-context</artifactId>
   <version>3.1.0.RELEASE</version>
</dependency>
<dependency>
 <groupId>org.springframework</groupId>
  <artifactId>spring-webmvc</artifactId>
   <version>3.1.0.RELEASE</version>
</dependency>

2- The necessary jars are in your classpath but are not deployed on tomcat.

For a cross browser implementation I'd sugguest you look at prototype.js $A function

copyed from 1.6.1:

function $A(iterable) {
  if (!iterable) return [];
  if ('toArray' in Object(iterable)) return iterable.toArray();
  var length = iterable.length || 0, results = new Array(length);
  while (length--) results[length] = iterable[length];
  return results;
}

It doesn't use Array.prototype.slice probably because it isn't available on every browser. I'm afraid the performance is pretty bad as there a the fall back is a javascript loop over the iterable.

MVC 5/6/Razor Pages

I think the best way is with strongly typed model, because Viewbags are being aboused too much already :)

MVC 5 example

Your Get Action

public async Task<ActionResult> Register()
    {
        var model = new RegistrationViewModel
        {
            Roles = GetRoles()
        };

        return View(model);
    }

Your View Model

    public class RegistrationViewModel
    {
        public string Name { get; set; }

        public int? RoleId { get; set; }

        public List<SelectListItem> Roles { get; set; }
    }    

Your View

    <div class="form-group">
        @Html.LabelFor(model => model.RoleId, htmlAttributes: new { @class = "col-form-label" })
        <div class="col-form-txt">
            @Html.DropDownListFor(model => model.RoleId, Model.Roles, "--Select Role--", new { @class = "form-control" })
            @Html.ValidationMessageFor(model => model.RoleId, "", new { @class = "text-danger" })
        </div>
    </div>                                   

Your Post Action

    [HttpPost, ValidateAntiForgeryToken]
    public async Task<ActionResult> Register(RegistrationViewModel model)
    {
        if (ModelState.IsValid)
        {
            var _roleId = model.RoleId, 

MVC 6 It'll be a little different

Get Action

public async Task<ActionResult> Register()
    {
        var _roles = new List<SelectListItem>();
        _roles.Add(new SelectListItem
        {
           Text = "Select",
           Value = ""
        });
        foreach (var role in GetRoles())
        {
          _roles.Add(new SelectListItem
          {
            Text = z.Name,
            Value = z.Id
          });
        }

        var model = new RegistrationViewModel
        {
            Roles = _roles
        };

        return View(model);
    }

Your View Model will be same as MVC 5

Your View will be like

<select asp-for="RoleId" asp-items="Model.Roles"></select>

Post will also be same

Razor Pages

Your Page Model

[BindProperty]
public int User User { get; set; } = 1;

public List<SelectListItem> Roles { get; set; }

public void OnGet()
{
    Roles = new List<SelectListItem> {
        new SelectListItem { Value = "1", Text = "X" },
        new SelectListItem { Value = "2", Text = "Y" },
        new SelectListItem { Value = "3", Text = "Z" },
   };
}

<select asp-for="User" asp-items="Model.Roles">
    <option value="">Select Role</option>
</select>

I hope it may help someone :)

From the official documentation, does it not seem that the sample() method is appropriate for this purpose?

import random

def random_digits(n):
    num = range(0, 10)
    lst = random.sample(num, n)
    print str(lst).strip('[]')

Output:

>>>random_digits(5)
2, 5, 1, 0, 4

If your code seems too unwieldy, a function might help:

def clamp(minvalue, value, maxvalue):
    return max(minvalue, min(value, maxvalue))

new_index = clamp(0, new_index, len(mylist)-1)

The window binding refers to a built-in object provided by the browser. It represents the browser window that contains the document. Calling its addEventListener method registers the second argument (callback function) to be called whenever the event described by its first argument occurs.

<p>Some paragraph.</p>
<script>
  window.addEventListener("click", () => {
    console.log("Test");
  });
</script>

Following points should be noted before select window or document to addEventListners

1. Most of the events are same for window or document but some events like resize, and other events related to loading, unloading, and opening/closing should all be set on the window.
2. Since window has the document it is good practice to use document to handle (if it can handle) since event will hit document first.
3. Internet Explorer doesn't respond to many events registered on the window,so you will need to use document for registering event.

Memory allocated on the heap can be subject to high-water marks. This is complicated by Python's internal optimizations for allocating small objects (PyObject_Malloc) in 4 KiB pools, classed for allocation sizes at multiples of 8 bytes -- up to 256 bytes (512 bytes in 3.3). The pools themselves are in 256 KiB arenas, so if just one block in one pool is used, the entire 256 KiB arena will not be released. In Python 3.3 the small object allocator was switched to using anonymous memory maps instead of the heap, so it should perform better at releasing memory.

Additionally, the built-in types maintain freelists of previously allocated objects that may or may not use the small object allocator. The int type maintains a freelist with its own allocated memory, and clearing it requires calling PyInt_ClearFreeList(). This can be called indirectly by doing a full gc.collect.

Try it like this, and tell me what you get. Here's the link for psutil.Process.memory_info.

import os
import gc
import psutil

proc = psutil.Process(os.getpid())
gc.collect()
mem0 = proc.get_memory_info().rss

# create approx. 10**7 int objects and pointers
foo = ['abc' for x in range(10**7)]
mem1 = proc.get_memory_info().rss

# unreference, including x == 9999999
del foo, x
mem2 = proc.get_memory_info().rss

# collect() calls PyInt_ClearFreeList()
# or use ctypes: pythonapi.PyInt_ClearFreeList()
gc.collect()
mem3 = proc.get_memory_info().rss

pd = lambda x2, x1: 100.0 * (x2 - x1) / mem0
print "Allocation: %0.2f%%" % pd(mem1, mem0)
print "Unreference: %0.2f%%" % pd(mem2, mem1)
print "Collect: %0.2f%%" % pd(mem3, mem2)
print "Overall: %0.2f%%" % pd(mem3, mem0)

Output:

Allocation: 3034.36%
Unreference: -752.39%
Collect: -2279.74%
Overall: 2.23%

Edit:

I switched to measuring relative to the process VM size to eliminate the effects of other processes in the system.

The C runtime (e.g. glibc, msvcrt) shrinks the heap when contiguous free space at the top reaches a constant, dynamic, or configurable threshold. With glibc you can tune this with mallopt (M_TRIM_THRESHOLD). Given this, it isn't surprising if the heap shrinks by more -- even a lot more -- than the block that you free.

In 3.x range doesn't create a list, so the test above won't create 10 million int objects. Even if it did, the int type in 3.x is basically a 2.x long, which doesn't implement a freelist.

Select * is a SQL antipattern. It should not be used in production code for many reasons including:

It takes a tiny bit longer to process. When things are run millions of times, those tiny bits can matter. A slow database where the slowness is caused by this type of sloppy coding throughout is the hardest kind to performance tune.

It means you are probably sending more data than you need which causes both server and network bottlenecks. If you have an inner join, the chances of sending more data than you need are 100%.

It causes maintenance problems especially when you have added new columns that you do not want seen everywhere. Further if you have a new column, you may need to do something to the interface to determine what to do with that column.

It can break views (I know this is true in SQl server, it may or may not be true in mysql).

If someone is silly enough to rebuild the tables with the columns in a differnt order (which you shouldn't do but it happens all teh time), all sorts of code can break. Espcially code for an insert for example where suddenly you are putting the city into the address_3 field becasue without specifying, the database can only go on the order of the columns. This is bad enough when the data types change but worse when the swapped columns have the same datatype becasue you can go for sometime inserting bad data that is a mess to clean up. You need to care about data integrity.

If it is used in an insert, it will break the insert if a new column is added in one table but not the other.

It might break triggers. Trigger problems can be difficult to diagnose.

Add up all this against the time it take to add in the column names (heck you may even have an interface that allows you to drag over the columns names (I know I do in SQL Server, I'd bet there is some way to do this is some tool you use to write mysql queries.) Let's see, "I can cause maintenance problems, I can cause performance problems and I can cause data integrity problems, but hey I saved five minutes of dev time." Really just put in the specific columns you want.

I also suggest you read this book: http://www.amazon.com/SQL-Antipatterns-Programming-Pragmatic-Programmers-ebook/dp/B00A376BB2/ref=sr_1_1?s=digital-text&ie=UTF8&qid=1389896688&sr=1-1&keywords=sql+antipatterns

Every instance of View calls getViewTreeObserver(). Now when holding an instance of ViewTreeObserver, you can add an OnScrollChangedListener() to it using the method addOnScrollChangedListener().

You can see more information about this class here.

It lets you be aware of every scrolling event - but without the coordinates. You can get them by using getScrollY() or getScrollX() from within the listener though.

scrollView.getViewTreeObserver().addOnScrollChangedListener(new OnScrollChangedListener() {
    @Override
    public void onScrollChanged() {
        int scrollY = rootScrollView.getScrollY(); // For ScrollView
        int scrollX = rootScrollView.getScrollX(); // For HorizontalScrollView
        // DO SOMETHING WITH THE SCROLL COORDINATES
    }
});

Check first your class loader.

ClassLoader classLoader = Thread.currentThread().getContextClassLoader();

if (classLoader == null) {
    classLoader = Class.class.getClassLoader();
}

classLoader.getResourceAsStream("xmlFileNameInJarFile.xml");

// xml file location at xxx.jar
// + folder
// + folder
// xmlFileNameInJarFile.xml

While not in the standard library exactly, https://github.com/swenson/sort has just two header files you can include to get access to a wide range of incredibly fast sorting routings, like so:

#define SORT_NAME int64
#define SORT_TYPE int64_t
#define SORT_CMP(x, y) ((x) - (y))
#include "sort.h"
/* You now have access to int64_quick_sort, int64_tim_sort, etc., e.g., */
int64_quick_sort(arr, 128); /* Assumes you have some int *arr or int arr[128]; */

This should be at least twice as fast as the standard library qsort, since it doesn't use function pointers, and has many other sorting algorithm options to choose from.

It's in C89, so should work in basically every C compiler.

$url='Your url'; // Specify your url
$data= array('parameterkey1'=>value,'parameterkey2'=>value); // Add parameters in key value
$ch = curl_init(); // Initialize cURL
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($data));
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_exec($ch);
curl_close($ch);

Ians Answer is good, but you should use const instead of let for the key because it never gets updated.

for (const key in myDictionary) {
    let value = myDictionary[key];
    // Use `key` and `value`
}

for development with Wildfly ( standalone.xml), add those loggers:

<logger category="org.hibernate.SQL">
   <level name="DEBUG"/>
</logger>
<logger category="org.hibernate.type.descriptor.sql">
   <level name="TRACE"/>
</logger>

No, Depends on the situation, sometimes it is legitimate and good design.

To understand why and when you need to call destructors explicitly, let's look at what happening with "new" and "delete".

To created an object dynamically, T* t = new T; under the hood: 1. sizeof(T) memory is allocated. 2. T's constructor is called to initialize the allocated memory. The operator new does two things: allocation and initialization.

To destroy the object delete t; under the hood: 1. T's destructor is called. 2. memory allocated for that object is released. the operator delete also does two things: destruction and deallocation.

One writes the constructor to do initialization, and destructor to do destruction. When you explicitly call the destructor, only the destruction is done, but not the deallocation.

A legitimate use of explicitly calling destructor, therefore, could be, "I only want to destruct the object, but I don't (or can't) release the memory allocation (yet)."

A common example of this, is pre-allocating memory for a pool of certain objects which otherwise have to be allocated dynamically.

When creating a new object, you get the chunk of memory from the pre-allocated pool and do a "placement new". After done with the object, you may want to explicitly call the destructor to finish the cleanup work, if any. But you won't actually deallocate the memory, as the operator delete would have done. Instead, you return the chunk to the pool for reuse.

Lots of good answers here, below is an approach using a couple of them which lets you write this:

void main()
{
    std::map<std::string, int> m { {"jim", 1000}, {"sally", 2000} };
    for (auto key : MapKeys(m))
        std::cout << key << std::endl;
}

If that's what you always wanted, then here is the code for MapKeys():

template <class MapType>
class MapKeyIterator {
public:
    class iterator {
    public:
        iterator(typename MapType::iterator it) : it(it) {}
        iterator operator++() { return ++it; }
        bool operator!=(const iterator & other) { return it != other.it; }
        typename MapType::key_type operator*() const { return it->first; }  // Return key part of map
    private:
        typename MapType::iterator it;
    };
private:
    MapType& map;
public:
    MapKeyIterator(MapType& m) : map(m) {}
    iterator begin() { return iterator(map.begin()); }
    iterator end() { return iterator(map.end()); }
};
template <class MapType>
MapKeyIterator<MapType> MapKeys(MapType& m)
{
    return MapKeyIterator<MapType>(m);
}

Bootstrap 5

<div class="input-group">
  <input type="text" class="form-control">
  <button class="btn btn-outline-secondary" type="button">Go</button>
</div>

Bootstrap 3 & 4

you may use the input-group button property to apply the button direct to the input-field.

<div class="input-group">
  <input type="text" class="form-control">
  <span class="input-group-btn">
    <button class="btn btn-default" type="button">Go!</button>
  </span>
</div><!-- /input-group -->

Take a look at BS4 or BS5 Input-Group doc for many more examples.

As biziclop mentioned, some sort of metric space tree would probably be your best option. I have experience using kd-trees and quad trees to do these sorts of range queries and they're amazingly fast; they're also not that hard to write. I'd suggest looking into one of these structures, as they also let you answer other interesting questions like "what's the closest point in my data set to this other point?"

In ASP.net MVC, you can use a FileContentResult and the File method:

public FileContentResult DownloadManifest() {
    byte[] csvData = getCsvData();
    return File(csvData, "text/csv", "filename.csv");
}

Not too sure to add opacity via CSS is such a good idea.
Opacity has that funny way to be applied to all content and childs from where you set it, with unexpected results in mixed of colours.
It has no really purpose in that case , for a bg color, in my opinion.
If you'd like to lay it hover the bg image, then you may use multiple backgrounds.
this color transparent could be applyed via an extra png repeated (or not with background-position),
CSS gradient (radial-) linear-gradient with rgba colors (starting and ending with same color) can achieve this as well. They are treated as background-image and can be used as filter.
Idem for text, if you want them a bit transparent, use rgba (okay to put text-shadow together).

I think that today, we can drop funny behavior of CSS opacity.

Here is a mixed of rgba used for opacity if you are curious dabblet.com/gist/5685845

In addition to the answer given by @ramin, if you already have BufferedReader or InputStream, it's possible to iterate through lines like this:

reader.lines().forEach(line -> {
    //...
});

or if you need to process it with given order:

reader.lines().forEachOrdered(line -> {
    //...
});

If you want to remove all the data from all your tables, you might want to try the command python manage.py flush. This will delete all of the data in your tables, but the tables themselves will still exist.

Seems like this config files are really confusing to clarify as their behaviour changes from the dev environment to deployment. Apparently a DLL can have its own config file, but once you copy and paste the dll (together with their config file) elsewhere, the whole thing stopped working. The only solution is to manually merge the app.config files into a single file, which will only be used by the exec. For e.g. myapp.exe will have a myapp.exe.config file that contains all settings for all dlls used by myapp.exe. I'm using VS 2008.

A blazingly faster approach is to do the multiplication in a vectorized manner instead of looping over the list. Numpy has already provided a very simply and handy way for this that you can use.

>>> import numpy as np
>>> 
>>> my_list = np.array([1, 2, 3, 4, 5])
>>> 
>>> my_list * 5
array([ 5, 10, 15, 20, 25])

Note that this doesn't work with Python's native lists. If you multiply a number with a list it will repeat the items of the as the size of that number.

In [15]: my_list *= 1000

In [16]: len(my_list)
Out[16]: 5000

If you want a pure Python-based approach using a list comprehension is basically the most Pythonic way to go.

In [6]: my_list = [1, 2, 3, 4, 5]

In [7]: [5 * i for i in my_list]
Out[7]: [5, 10, 15, 20, 25]

Beside list comprehension, as a pure functional approach, you can also use built-in map() function as following:

In [10]: list(map((5).__mul__, my_list))
Out[10]: [5, 10, 15, 20, 25]

This code passes all the items within the my_list to 5's __mul__ method and returns an iterator-like object (in python-3.x). You can then convert the iterator to list using list() built in function (in Python-2.x you don't need that because map return a list by default).

benchmarks:

In [18]: %timeit [5 * i for i in my_list]
463 ns ± 10.6 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

In [19]: %timeit list(map((5).__mul__, my_list))
784 ns ± 10.7 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

In [20]: %timeit [5 * i for i in my_list * 100000]
20.8 ms ± 115 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

In [21]: %timeit list(map((5).__mul__, my_list * 100000))
30.6 ms ± 169 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)


In [24]: arr = np.array(my_list * 100000)

In [25]: %timeit arr * 5
899 µs ± 4.98 µs per loop (mean ± std. dev. of 7 runs, 1000 loops each)

http://www.cybertechquestions.com/select-across-multiple-tables-in-entity-framework-resulting-in-a-generic-iqueryable_222801.html

It's an interesting question, because it shows that there are a lot of different approaches to achieve the same result. Below I show three different implementations.

Default methods in Collection Framework: Java 8 added some methods to the collections classes, that are not directly related to the Stream API. Using these methods, you can significantly simplify the implementation of the non-stream implementation:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    Map<String, DataSet> result = new HashMap<>();
    multiDataPoints.forEach(pt ->
        pt.keyToData.forEach((key, value) ->
            result.computeIfAbsent(
                key, k -> new DataSet(k, new ArrayList<>()))
            .dataPoints.add(new DataPoint(pt.timestamp, value))));
    return result.values();
}

Stream API with flatten and intermediate data structure: The following implementation is almost identical to the solution provided by Stuart Marks. In contrast to his solution, the following implementation uses an anonymous inner class as intermediate data structure.

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .flatMap(mdp -> mdp.keyToData.entrySet().stream().map(e ->
            new Object() {
                String key = e.getKey();
                DataPoint dataPoint = new DataPoint(mdp.timestamp, e.getValue());
            }))
        .collect(
            collectingAndThen(
                groupingBy(t -> t.key, mapping(t -> t.dataPoint, toList())),
                m -> m.entrySet().stream().map(e -> new DataSet(e.getKey(), e.getValue())).collect(toList())));
}

Stream API with map merging: Instead of flattening the original data structures, you can also create a Map for each MultiDataPoint, and then merge all maps into a single map with a reduce operation. The code is a bit simpler than the above solution:

Collection<DataSet> convert(List<MultiDataPoint> multiDataPoints) {
    return multiDataPoints.stream()
        .map(mdp -> mdp.keyToData.entrySet().stream()
            .collect(toMap(e -> e.getKey(), e -> asList(new DataPoint(mdp.timestamp, e.getValue())))))
        .reduce(new HashMap<>(), mapMerger())
        .entrySet().stream()
        .map(e -> new DataSet(e.getKey(), e.getValue()))
        .collect(toList());
}

You can find an implementation of the map merger within the Collectors class. Unfortunately, it is a bit tricky to access it from the outside. Following is an alternative implementation of the map merger:

<K, V> BinaryOperator<Map<K, List<V>>> mapMerger() {
    return (lhs, rhs) -> {
        Map<K, List<V>> result = new HashMap<>();
        lhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        rhs.forEach((key, value) -> result.computeIfAbsent(key, k -> new ArrayList<>()).addAll(value));
        return result;
    };
}

A little bit info about this keyword

Let's log this keyword to the console in global scope without any more code but

console.log(this)

In Client/Browser this keyword is a global object which is window

console.log(this === window) // true

and

In Server/Node/Javascript runtime this keyword is also a global object which is module.exports

console.log(this === module.exports) // true
console.log(this === exports) // true

Keep in mind exports is just a reference to module.exports

Very simple solution. Just rename your database and configure your new database name in your project.

The problem is the when you import your database, you got any errors and then the database will be corrupted. The log files will have the corrupted database name. You can rename your database easily using phpmyadmin for mysql.

Presuming that you are running the 64bit Ubuntu, the fix suggested for "Issue 82711" should solve your problem.

sudo apt-get install lib32z1 lib32ncurses5 lib32bz2-1.0 lib32stdc++6

Update: For Ubuntu 15.10 & 16.04 sudo apt-get install lib32z1 lib32ncurses5 lib32stdc++6

I append one space for every element of the hash to see it well:

print map {$_ . " "} %h, "\n";

I can't say how much this might help you, but just found a solution to something similar problem which I faced. In the Pivot-

1. Right click and choose Pivot table options
2. Choose the display option
3. uncheck the first 'Show expand/Collapse buttons'
4. check the 'Classic PivotTable Layout(enables dragging of fields in the grid)
5. click ok.

This would refine the data. Then, I had just copy and pasted this data in a new tab wherein I had applied the filters to my Total column with values greater than certain percentage.

This did work in my case and hope it helps you too.

The real solution that I found for this issue was by disabling any XML Format post processors. I have added a post processor called "jp@gc - XML Format Post Processor" and started noticing the error "Fatal Error :1:1: Content is not allowed in prolog"

By disabling the post processor had stopped throwing those errors.

(a[n:]+[default])[0]

This is probably better as a gets larger

(a[n:n+1]+[default])[0]

This works because if a[n:] is an empty list if n => len(a)

Here is an example of how this works with range(5)

>>> range(5)[3:4]
[3]
>>> range(5)[4:5]
[4]
>>> range(5)[5:6]
[]
>>> range(5)[6:7]
[]

And the full expression

>>> (range(5)[3:4]+[999])[0]
3
>>> (range(5)[4:5]+[999])[0]
4
>>> (range(5)[5:6]+[999])[0]
999
>>> (range(5)[6:7]+[999])[0]
999

The != operator most certainly does exist! It is an alias for the standard <> operator.

Perhaps your fields are not actually empty strings, but instead NULL?

To compare to NULL you can use IS NULL or IS NOT NULL or the null safe equals operator <=>.

i think the simple solution is:

sh /dir/* > ./result.txt

I would probably use regexp matches if the input has only a few valid entries. E.g. only the "start" and "stop" are valid actions.

if [[ "${ACTION,,}" =~ ^(start|stop)$ ]]; then
  echo "valid action"
fi

Note that I lowercase the variable $ACTION by using the double comma's. Also note that this won't work on too aged bash versions out there.

In case it helps anyone... I was having a lot of trouble with setting up notifications using the support package when testing against newer an older API's. I was able to get them to work on the newer device but would get an error testing on the old device. What finally got it working for me was to delete all the imports related to the notification functions. In particular the NotificationCompat and the TaskStackBuilder. It seems that while setting up my code in the beginning the imports where added from the newer build and not from the support package. Then when I wanted to implement these items later in eclipse, I wasn't prompted to import them again. Hope that makes sense, and that it helps someone else out :)

You write like this-:

xAxis: {
        type: 'datetime',
        dateTimeLabelFormats: {
           day: '%d %b %Y'    //ex- 01 Jan 2016
        }
}

also check for other datetime format

http://api.highcharts.com/highcharts#xAxis.dateTimeLabelFormats

A Date object has no format, it is a representation. The date can be presented by a String with the format you like.

E.g. "yyyy-MM-dd", "yy-MMM-dd", "dd-MMM-yy" and etc.

To acheive this you can get the use of the SimpleDateFormat

Try this,

        String inputString = "19/05/2009"; // i.e. (dd/MM/yyyy) format

        SimpleDateFormat fromUser = new SimpleDateFormat("dd/MM/yyyy"); 
        SimpleDateFormat myFormat = new SimpleDateFormat("yyyy-MM-dd");

        try {
            Date dateFromUser = fromUser.parse(inputString); // Parse it to the exisitng date pattern and return Date type
            String dateMyFormat = myFormat.format(dateFromUser); // format it to the date pattern you prefer
            System.out.println(dateMyFormat); // outputs : 2009-05-19

        } catch (ParseException e) {
            e.printStackTrace();
        }

This outputs : 2009-05-19

Cursors are used when your select query returns multiple rows. So, rather using cursor in case when you want aggregates or single rowdata you could use a procedure/function without cursor as well like

  Create Procedure sample(id 
    varchar2(20))as 
    Select count(*) into x from table 
    where 
       Userid=id;
     End ;

And then simply call the procedure

   Begin
   sample(20);
   End

This is the actual use of procedure/function mostly wrapping and storing queries that are complex or that requires repeated manipulation with same logic but different data

To get the native reference to something like an ion-input, ry using this

@ViewChild('fileInput', { read: ElementRef }) fileInput: ElementRef;

and then

this.fileInput.nativeElement.querySelector('input').click()

An optional prefix ! which negates the pattern; any matching file excluded by a previous pattern will become included again. If a negated pattern matches, this will override lower precedence patterns sources.

If you want emulate enum of C/C++ (base num and nexts incrementals):

enum ids {
    OPEN, CLOSE;
    //
    private static final int BASE_ORDINAL = 100;
    public int getCode() {
        return ordinal() + BASE_ORDINAL;
    }
};

public class TestEnum {
    public static void main (String... args){
        for (ids i : new ids[] { ids.OPEN, ids.CLOSE }) {
            System.out.println(i.toString() + " " + 
                i.ordinal() + " " + 
                i.getCode());
        }
    }
}

OPEN 0 100
CLOSE 1 101

I tried with the correct answer by @Lahiru, but did not work with MySQL server version 8.0.16 (Community) on macOS Mojave.

Followed the instructions by Sameer Choudhary above and with some adjustments, I was able to change root password and enable root access from localhost.

Update: All of these are not required, if you are installing on Mac OS using homebrew: "brew install mysql"

<div style="width:100px;height:100px;overflow-x:hidden;overflow-y:auto;background-color:#000000">

You can use python code directly in batch file, https://gist.github.com/jadient/9849314.

@echo off & python -x "%~f0" %* & goto :eof
import sys
print("Hello World!")

See explanation, Python command line -x option.

Seeding the rand()

void srand (unsigned int seed)

This function establishes seed as the seed for a new series of pseudo-random numbers. If you call rand before a seed has been established with srand, it uses the value 1 as a default seed.

To produce a different pseudo-random series each time your program is run, do srand (time (0))

My personal preference is not to save the images to a database as such. Save the image somewhere in the file system and save a reference in the database.

I was recently working with IPFS and worked this out. A curl example for IPFS to upload a file looks like this:

curl -i -H "Content-Type: multipart/form-data; boundary=CUSTOM" -d $'--CUSTOM\r\nContent-Type: multipart/octet-stream\r\nContent-Disposition: file; filename="test"\r\n\r\nHello World!\n--CUSTOM--' "http://localhost:5001/api/v0/add"

The basic idea is that each part (split by string in boundary with --) has it's own headers (Content-Type in the second part, for example.) The FormData object manages all this for you, so it's a better way to accomplish our goals.

This translates to fetch API like this:

const formData = new FormData()
formData.append('blob', new Blob(['Hello World!\n']), 'test')

fetch('http://localhost:5001/api/v0/add', {
  method: 'POST',
  body: formData
})
.then(r => r.json())
.then(data => {
  console.log(data)
})

A solution that I like, because it keeps rspec output separate from actual rails log output, is to do the following:

• Open a second terminal window or tab, and arrange it so that you can see both the main terminal you're running rspec on as well as the new one.
• Run a tail command in the second window so you see the rails log in the test environment. By default this can be like $ tail -f $RAILS_APP_DIR/logs/test.log or tail -f $RAILS_APP_DIR\logs\test.log for Window users
• Run your rspec suites

If you are running a multi-pane terminal like iTerm, this becomes even more fun and you have rspec and the test.log output side by side.

Using your radio button's ID, try rb.SelectedValue.

Another possibility for this warning (and, most likely, problems with app behavior) is that the original author of the app relied on session.auto_start being on (defaults to off)

If you don't want to mess with the code and just need it to work, you can always change php configuration and restart php-fpm (if this is a web app):

/etc/php.d/my-new-file.ini :

session.auto_start = 1

(This is correct for CentOS 8, adjust for your OS/packaging)

If you installed GitHubDesktop then the path for git.exe will be ,

C:\Users\<'Username'>\AppData\Local\GitHubDesktop\app-1.1.1\resources\app\git\cmd

Add this path to the environment variables by following,

** (Note: \cmd at the end, not \cmd\git.exe).**

Navigate to the Environmental Variables Editor and find the Path variable in the “System Variables” section. Click Edit… and paste the URL of Git to the end. Save!

Now open a new cmd and type command git. If you are able to see the git usage then it's done.

Now you can execute your command to install your package.

ex: npm install native-base --save

To create your cell styles see: http://poi.apache.org/spreadsheet/quick-guide.html#CustomColors.

Custom colors

HSSF:

HSSFWorkbook wb = new HSSFWorkbook();
HSSFSheet sheet = wb.createSheet();
HSSFRow row = sheet.createRow((short) 0);
HSSFCell cell = row.createCell((short) 0);
cell.setCellValue("Default Palette");

//apply some colors from the standard palette,
// as in the previous examples.
//we'll use red text on a lime background

HSSFCellStyle style = wb.createCellStyle();
style.setFillForegroundColor(HSSFColor.LIME.index);
style.setFillPattern(HSSFCellStyle.SOLID_FOREGROUND);

HSSFFont font = wb.createFont();
font.setColor(HSSFColor.RED.index);
style.setFont(font);

cell.setCellStyle(style);

//save with the default palette
FileOutputStream out = new FileOutputStream("default_palette.xls");
wb.write(out);
out.close();

//now, let's replace RED and LIME in the palette
// with a more attractive combination
// (lovingly borrowed from freebsd.org)

cell.setCellValue("Modified Palette");

//creating a custom palette for the workbook
HSSFPalette palette = wb.getCustomPalette();

//replacing the standard red with freebsd.org red
palette.setColorAtIndex(HSSFColor.RED.index,
        (byte) 153,  //RGB red (0-255)
        (byte) 0,    //RGB green
        (byte) 0     //RGB blue
);
//replacing lime with freebsd.org gold
palette.setColorAtIndex(HSSFColor.LIME.index, (byte) 255, (byte) 204, (byte) 102);

//save with the modified palette
// note that wherever we have previously used RED or LIME, the
// new colors magically appear
out = new FileOutputStream("modified_palette.xls");
wb.write(out);
out.close();

XSSF:

 XSSFWorkbook wb = new XSSFWorkbook();
    XSSFSheet sheet = wb.createSheet();
    XSSFRow row = sheet.createRow(0);
    XSSFCell cell = row.createCell( 0);
    cell.setCellValue("custom XSSF colors");

    XSSFCellStyle style1 = wb.createCellStyle();
    style1.setFillForegroundColor(new XSSFColor(new java.awt.Color(128, 0, 128)));
    style1.setFillPattern(CellStyle.SOLID_FOREGROUND);

Neater still, instead of the typical href="#" or href="javascript:void" or href="whatever", I think this makes much more sense:

var el = document.getElementById('foo');
el.onclick = showFoo;


function showFoo() {
  alert('I am foo!');
  return false;
}

<a href="no-javascript.html" title="Get some foo!" id="foo">Show me some foo</a>

If Javascript fails, there is some feedback. Furthermore, erratic behavior (page jumping in the case of href="#", visiting the same page in the case of href="") is eliminated.

I think it is better to copy files from your local computer, because if files number or file size is very big, copying process could be interrupted if your current ssh session would be lost (broken pipe or whatever).

If you have configured ssh key to connect to your remote server, you could use the following command:

rsync -avP -e "ssh -i /home/local_user/ssh/key_to_access_remote_server.pem" remote_user@remote_host.ip:/home/remote_user/file.gz /home/local_user/Downloads/

Where v option is --verbose, a option is --archive - archive mode, P option same as --partial - keep partially transferred files, e option is --rsh=COMMAND - specifying the remote shell to use.

the most simple solution for removing the brackets is,

1.convert the arraylist into string with .toString() method.

2.use String.substring(1,strLen-1).(where strLen is the length of string after conversion from arraylist).

3.Hurraaah..the result string is your string with removed brackets.

hope this is useful...:-)

If you use constraints (and so don't have the frame sizes) then you can add a border view with the required constraints

// MARK: - Add a border to one side of a view

public enum BorderSide {
    case top, bottom, left, right
}

extension UIView {
    public func addBorder(side: BorderSide, color: UIColor, width: CGFloat) {
        let border = UIView()
        border.translatesAutoresizingMaskIntoConstraints = false
        border.backgroundColor = color
        self.addSubview(border)

        let topConstraint = topAnchor.constraint(equalTo: border.topAnchor)
        let rightConstraint = trailingAnchor.constraint(equalTo: border.trailingAnchor)
        let bottomConstraint = bottomAnchor.constraint(equalTo: border.bottomAnchor)
        let leftConstraint = leadingAnchor.constraint(equalTo: border.leadingAnchor)
        let heightConstraint = border.heightAnchor.constraint(equalToConstant: width)
        let widthConstraint = border.widthAnchor.constraint(equalToConstant: width)


        switch side {
        case .top:
            NSLayoutConstraint.activate([leftConstraint, topConstraint, rightConstraint, heightConstraint])
        case .right:
            NSLayoutConstraint.activate([topConstraint, rightConstraint, bottomConstraint, widthConstraint])
        case .bottom:
            NSLayoutConstraint.activate([rightConstraint, bottomConstraint, leftConstraint, heightConstraint])
        case .left:
            NSLayoutConstraint.activate([bottomConstraint, leftConstraint, topConstraint, widthConstraint])
        }
    }
}

Then set it something like the below

myButton.addBorder(side: .left, color: UIColor.lightGray, width: 1)

Put in other words, this error is telling you that SQL Server does not know which B to select from the group.

Either you want to select one specific value (e.g. the MIN, SUM, or AVG) in which case you would use the appropriate aggregate function, or you want to select every value as a new row (i.e. including B in the GROUP BY field list).

Consider the following data:

ID  A   B
1   1  13
1   1  79
1   2  13
1   2  13
1   2  42

The query

SELECT A, COUNT(B) AS T1 
FROM T2 
GROUP BY A

would return:

A  T1
1  2
2  3

which is all well and good.

However consider the following (illegal) query, which would produce this error:

SELECT A, COUNT(B) AS T1, B 
FROM T2 
GROUP BY A

And its returned data set illustrating the problem:

A  T1  B
1  2   13? 79? Both 13 and 79 as separate rows? (13+79=92)? ...?
2  3   13? 42? ...?

However, the following two queries make this clear, and will not cause the error:

1. Using an aggregate

   SELECT A, COUNT(B) AS T1, SUM(B) AS B
   FROM T2
   GROUP BY A
   

   would return:

   A  T1  B
   1  2   92
   2  3   68
   

2. Adding the column to the GROUP BY list

   SELECT A, COUNT(B) AS T1, B
   FROM T2
   GROUP BY A, B
   

   would return:

   A  T1  B
   1  1   13
   1  1   79
   2  2   13
   2  1   42
   

list1 = (x[0] for x in source_list)
list2 = (x[1] for x in source_list)
