In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

when you will type anaconda in windows 10 search bar it will give you the list as then in terminal you have to type anaconda-navigator as it will start anaconda on your machine.

I got this error loading a http:// URL where the server replied with a redirect to https. After changing the URL I pass to WKWebView to https://... it worked.

I got the same issues while making a build of Ionic 1 project.

I was able to solve the issue after deleting the file CDVLogger.h & CDVLogger.m

Another easy way of solving this error is right clicking in the console and click on Terminate/Disconnect All. Afterwards run the application it should work fine.

I could use the GetBody from Request package.

Look this comment in source code from request.go in net/http:

GetBody defines an optional func to return a new copy of Body. It is used for client requests when a redirect requires reading the body more than once. Use of GetBody still requires setting Body. For server requests it is unused."

GetBody func() (io.ReadCloser, error)

This way you can get the body request without make it empty.

Sample:

getBody := request.GetBody
copyBody, err := getBody()
if err != nil {
    // Do something return err
}
http.DefaultClient.Do(request)

Is that your private IP address? If so you'll need to use your public one. Go to ipchicken to find out what it is. I know you are in the same LAN, but try this to see if it resolves any issues.

Just add <br> where you would like to make the new line.

$S$: a set of shops
<br>
$I$: a set of items M wants to get

Because jupyter notebook markdown cell is a superset of HTML.

Note that newlines using <br> does not persist when exporting or saving the notebook to a pdf (using "Download as > PDF via LaTeX"). It is probably treating each <br> as a space.

I got it like this

public void onClick(View v){
        v.findViewById(R.id.textView).setBackgroundColor(R.drawable.selector_row);

You did not post the code generated by the compiler, so there' some guesswork here, but even without having seen it, one can say that this:

test rax, 1
jpe even

... has a 50% chance of mispredicting the branch, and that will come expensive.

The compiler almost certainly does both computations (which costs neglegibly more since the div/mod is quite long latency, so the multiply-add is "free") and follows up with a CMOV. Which, of course, has a zero percent chance of being mispredicted.

Here you go: Working Fidddle

$(function(){
  var dateFormat = 'DD-MM-YYYY';
  alert(moment(moment("2012-10-19").format(dateFormat),dateFormat,true).isValid());
});

This probably because of your gzip version incompatibility.

Check these points first:

which gzip

/usr/bin/gzip or /bin/gzip

It should be either /bin/gzip or /usr/bin/gzip. If your gzip points to some other gzip application please try by removing that path from your PATH env variable.

Next is

gzip -V

gzip 1.3.5 (2002-09-30)

Your problem can be resolve with these check points.

@niutech I was having the similar issue which is caused by Rocket Loader Module by Cloudflare. Just disable it for the website and it will sort out all your related issues.

If you are using ambassador to any other API gateway for service located in another namespace it's always suggested to use :

            Use : <service name>
            Use : <service.name>.<namespace name>
            Not : <service.name>.<namespace name>.svc.cluster.local

it will be like : servicename.namespacename.svc.cluster.local

this will send request to a particular service inside the namespace you have mention.

example:

kind: Service
apiVersion: v1
metadata:
  name: service
spec:
  type: ExternalName
  externalName: <servicename>.<namespace>.svc.cluster.local

Here replace the <servicename> and <namespace> with the appropriate value.

In Kubernetes, namespaces are used to create virtual environment but all are connect with each other.

From cron manual http://man7.org/linux/man-pages/man5/crontab.5.html:

Lists are allowed. A list is a set of numbers (or ranges) separated by commas. Examples: "1,2,5,9", "0-4,8-12".

So in this case it would be:

30 10,14 * * *

I made an easy to use function to rename multiple columns for a pyspark dataframe, in case anyone wants to use it:

def renameCols(df, old_columns, new_columns):
    for old_col,new_col in zip(old_columns,new_columns):
        df = df.withColumnRenamed(old_col,new_col)
    return df

old_columns = ['old_name1','old_name2']
new_columns = ['new_name1', 'new_name2']
df_renamed = renameCols(df, old_columns, new_columns)

Be careful, both lists must be the same length.

You can use dirname:

os.path.dirname(path)

Return the directory name of pathname path. This is the first element of the pair returned by passing path to the function split().

And given the full path, then you can split normally to get the last portion of the path. For example, by using basename:

os.path.basename(path)

Return the base name of pathname path. This is the second element of the pair returned by passing path to the function split(). Note that the result of this function is different from the Unix basename program; where basename for '/foo/bar/' returns 'bar', the basename() function returns an empty string ('').

All together:

>>> import os
>>> path=os.path.dirname("C:/folder1/folder2/filename.xml")
>>> path
'C:/folder1/folder2'
>>> os.path.basename(path)
'folder2'

Sounds like you probably want a simple method like this:

public String getValueOrDefault(String value, String defaultValue) {
    return isNotNullOrEmpty(value) ? value : defaultValue;
}

Then:

String result = getValueOrDefault(System.getProperty("XYZ"), "default");

At this point, you don't need temp... you've effectively used the method parameter as a way of initializing the temporary variable.

If you really want temp and you don't want an extra method, you can do it in one statement, but I really wouldn't:

public class Test {
    public static void main(String[] args) {
        String temp, result = isNotNullOrEmpty(temp = System.getProperty("XYZ")) ? temp : "default";
        System.out.println("result: " + result);
        System.out.println("temp: " + temp);
    }

    private static boolean isNotNullOrEmpty(String str) {
        return str != null && !str.isEmpty();
    }
}

Swift is worry that your case statement is not covering all cases, to fix it you need to create a default case:

do {
    let sandwich = try makeMeSandwich(kitchen)
    print("i eat it \(sandwich)")
} catch SandwichError.NotMe {
    print("Not me error")
} catch SandwichError.DoItYourself {
    print("do it error")
} catch Default {
    print("Another Error")
}

Android Supports SSL implementation by default except for Android N (API level 24) and below Android 5.1 (API level 22)
I was getting the error when making the API call below API level 22 devices after implementing SSL at the server side; that was while creating OkHttpClient client object, and fixed by adding connectionSpecs() method OkHttpClient.Builder class.

the error received was

response failure: javax.net.ssl.SSLException: SSL handshake aborted: ssl=0xb8882c00: I/O error during system call, Connection reset by peer

so I fixed this by added the check like

if ( Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP_MR1) {
            // Do something for below api level 22
            List<ConnectionSpec> specsList = getSpecsBelowLollipopMR1(okb);
            if (specsList != null) {
                okb.connectionSpecs(specsList);
            }
        }

Also for the Android N (API level 24); I was getting the error while making the HTTP call like

HTTP FAILED: javax.net.ssl.SSLHandshakeException: Handshake failed

and this is fixed by adding the check for Android 7 particularly, like

if (android.os.Build.VERSION.SDK_INT == Build.VERSION_CODES.N){
            // Do something for naugat ; 7
            okb.connectionSpecs(Collections.singletonList(getSpec()));
        }

So my final OkHttpClient object will be like:

         OkHttpClient client
         HttpLoggingInterceptor httpLoggingInterceptor2 = new
         HttpLoggingInterceptor();
         httpLoggingInterceptor2.setLevel(HttpLoggingInterceptor.Level.BODY);

         OkHttpClient.Builder okb = new OkHttpClient.Builder()
                 .addInterceptor(httpLoggingInterceptor2)
               .addInterceptor(new Interceptor() {
                     @Override
                     public Response intercept(Chain chain) throws IOException {
                         Request request = chain.request();
                         Request request2 = request.newBuilder().addHeader(AUTH_KEYWORD, AUTH_TYPE_JW + " " + password).build();
                         return chain.proceed(request2);
                     }
                 }).connectTimeout(30, TimeUnit.SECONDS)
                 .writeTimeout(30, TimeUnit.SECONDS)
                 .readTimeout(30, TimeUnit.SECONDS);

         if (android.os.Build.VERSION.SDK_INT == Build.VERSION_CODES.N){
             // Do something for naugat ; 7
             okb.connectionSpecs(Collections.singletonList(getSpec()));
         }

         if ( Build.VERSION.SDK_INT < Build.VERSION_CODES.LOLLIPOP_MR1) {
             List<ConnectionSpec> specsList = getSpecsBelowLollipopMR1(okb);
             if (specsList != null) {
                 okb.connectionSpecs(specsList);
             }
         }

         //init client
         client = okb.build();

getSpecsBelowLollipopMR1 function be like,

   private List<ConnectionSpec> getSpecsBelowLollipopMR1(OkHttpClient.Builder okb) {

        try {

            SSLContext sc = SSLContext.getInstance("TLSv1.2");
            sc.init(null, null, null);
            okb.sslSocketFactory(new Tls12SocketFactory(sc.getSocketFactory()));

            ConnectionSpec cs = new ConnectionSpec.Builder(ConnectionSpec.MODERN_TLS)
                    .tlsVersions(TlsVersion.TLS_1_2)
                    .build();

            List<ConnectionSpec> specs = new ArrayList<>();
            specs.add(cs);
            specs.add(ConnectionSpec.COMPATIBLE_TLS);

            return specs;

        } catch (Exception exc) {
            Timber.e("OkHttpTLSCompat Error while setting TLS 1.2"+ exc);

            return null;
        }
    }

The simplest way to get an input box is with the Read-Host cmdlet and -AsSecureString parameter.

$us = Read-Host 'Enter Your User Name:' -AsSecureString
$pw = Read-Host 'Enter Your Password:' -AsSecureString

This is especially useful if you are gathering login info like my example above. If you prefer to keep the variables obfuscated as SecureString objects you can convert the variables on the fly like this:

[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))
[Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($pw))

If the info does not need to be secure at all you can convert it to plain text:

$user = [Runtime.InteropServices.Marshal]::PtrToStringAuto([Runtime.InteropServices.Marshal]::SecureStringToBSTR($us))

Read-Host and -AsSecureString appear to have been included in all PowerShell versions (1-6) but I do not have PowerShell 1 or 2 to ensure the commands work identically. https://docs.microsoft.com/en-us/powershell/module/microsoft.powershell.utility/read-host?view=powershell-3.0

Here is a cleaner way to show them (technically without symbolic links):

ls -1 /usr/bin/python* | grep '[2-3].[0-9]$'

Where grep filters the output of ls that that has that numeric pattern at the end ($).

Or using find:

find /usr/bin/python* ! -type l

Which shows all the different (!) of symbolic link type (-type l).

Try to organize by folder:

baseTypes.ts

export class Animal {
    move() { /* ... */ }
}

export class Plant {
    photosynthesize() { /* ... */ }
}

dog.ts

import b = require('./baseTypes');

export class Dog extends b.Animal {
    woof() { }
}   

tree.ts

import b = require('./baseTypes');

class Tree extends b.Plant {
}

LivingThings.ts

import dog = require('./dog')
import tree = require('./tree')

export = {
    dog: dog,
    tree: tree
}

main.ts

import LivingThings = require('./LivingThings');
console.log(LivingThings.Tree)
console.log(LivingThings.Dog)

The idea is that your module themselves shouldn't care / know they are participating in a namespace, but this exposes your API to the consumer in a compact, sensible way which is agnostic to which type of module system you are using for the project.

On Xamarin.Android, It works for me and need change layout

 var layout = recyclerView.GetLayoutManager() as GridLayoutManager;
 layout.SpanCount = GetItemPerRow(Context);
 recyclerView.SetAdapter(null);
 recyclerView.SetAdapter(adapter); //reset

There are two alternatives that'll work for sure:

1. Clean your project and then build.

If the above method didn't worked, try the next.

2. Add the following to build.gradle file at app level

   defaultConfig {   
   
   multiDexEnabled true
   
   }
   

There is no JavaScript function to achieve this. However, you could set a boolean value to true when you add the listener, and false when you remove it. Then check against this boolean before potentially adding a duplicate event listener.

Possible duplicate: How to check whether dynamically attached event listener exists or not?

I faced same problem. And got the solution when I use this code to call context. I use Grid Layout. If you use another one you can change.

   recyclerView.setLayoutManager(new GridLayoutManager(getActivity(),1));

if you have adapter to set. So you can follow this. Just call the getContext

  adapter = new Adapter(getContext(), myModelList);

If you have Toast to show, use same thing above

   Toast.makeText(getContext(), "Error in "+e, Toast.LENGTH_SHORT).show();

Hope this will work.

Yes unfortunately it will always load the full file. If you're doing this repeatedly probably best to extract the sheets to separate CSVs and then load separately. You can automate that process with d6tstack which also adds additional features like checking if all the columns are equal across all sheets or multiple Excel files.

import d6tstack
c = d6tstack.convert_xls.XLStoCSVMultiSheet('multisheet.xlsx')
c.convert_all() # ['multisheet-Sheet1.csv','multisheet-Sheet2.csv']

See d6tstack Excel examples

Tried on Playground

class MyClass {

struct Constants {
static let testStr = "test"
static let testStrLen = testStr.characters.count
//testInt will not be accessable by other classes in different swift files
private static let testInt = 1
static func singletonFunction()
{
//accessable
print("Print singletonFunction testInt=\(testInt)")
var newInt = testStrLen
newInt = newInt + 1
print("Print singletonFunction testStr=\(testStr)")
}
}
func ownFunction() {
//not accessable
//var newInt1 = Constants.testInt + 1
var newInt2 = Constants.testStrLen
newInt2 = newInt2 + 1
print("Print ownFunction testStr=\(Constants.testStr)")
print("Print ownFunction newInt2=\(newInt2)")
}
}
let newInt = MyClass.Constants.testStrLen
print("Print testStr=\(MyClass.Constants.testStr)")
print("Print testInt=\(newInt)")
let myClass = MyClass()
myClass.ownFunction()
MyClass.Constants.singletonFunction()

If you want to add onClick() to the child view of items, for example, a button in item, I found that you can do it easily in onCreateViewHolder() of your own RecyclerView.Adapter just like this:

        @Override
        public RecyclerView.ViewHolder onCreateViewHolder(ViewGroup parent, int viewType) {
            View v = LayoutInflater
                    .from(parent.getContext())
                    .inflate(R.layout.cell, null);

            Button btn = (Button) v.findViewById(R.id.btn);
            btn.setOnClickListener(new View.OnClickListener() {
                @Override
                public void onClick(View v) {
                    //do it
                }
            });

            return new MyViewHolder(v);
        }

i don't know whether it's a good way, but it works well. If anyone has a better idea, very glad to tell me and correct my answer! :)

jww is right — you're referencing the wrong intermediate certificate.

As you have been issued with a SHA256 certificate, you will need the SHA256 intermediate. You can grab it from here: http://secure2.alphassl.com/cacert/gsalphasha2g2r1.crt

Find spring-boot-starter-test in your pom.xml and modify it as follows:

It fixed error like:

_Caused by: java.lang.IllegalArgumentException:_ **LoggerFactory** is not a **Logback LoggerContext** but *Logback* is on the classpath.

I solved my problem simply using ng-init for default selection instead of ng-checked

<div ng-init="person.billing=FALSE"></div>
<input id="billing-no" type="radio" name="billing" ng-model="person.billing" ng-value="FALSE" />
<input id="billing-yes" type="radio" name="billing" ng-model="person.billing" ng-value="TRUE" />

You could add to a set until you reach n:

setOfNumbers = set()
while len(setOfNumbers) < n:
    setOfNumbers.add(random.randint(numLow, numHigh))

Be careful of having a smaller range than will fit in n. It will loop forever, unable to find new numbers to insert up to n

Using the DISTINCT flag will remove duplicate rows.

SELECT DISTINCT
C.Content_ID,
C.Content_Title,
M.Media_Id

FROM tbl_Contents C
LEFT JOIN tbl_Media M ON M.Content_Id = C.Content_Id 
ORDER BY C.Content_DatePublished ASC

What you need is properly a service:

.factory('DataLayer', ['$http',

    function($http) {

        var factory = {};
        var locations;

        factory.getLocations = function(success) {
            if(locations){
                success(locations);
                return;
            }
            $http.get('locations/locations.json').success(function(data) {
                locations = data;
                success(locations);
            });
        };

        return factory;
    }
]);

The locations would be cached in the service which worked as singleton model. This is the right way to fetch data.

Use this service DataLayer in your controller and directive is ok as following:

appControllers.controller('dummyCtrl', function ($scope, DataLayer) {
    DataLayer.getLocations(function(data){
        $scope.locations = data;
    });
});

.directive('map', function(DataLayer) {
    return {
        restrict: 'E',
        replace: true,
        template: '<div></div>',
        link: function(scope, element, attrs) {

            DataLayer.getLocations(function(data) {
                angular.forEach(data, function(location, key){
                    //do something
                });
            });
        }
    };
});

I wrote an article on topis how to [manually install curl on debian linu][1]x.

[1]: http://www.jasom.net/how-to-install-curl-command-manually-on-debian-linux. This is its shortcut:

1. cd /usr/local/src
2. wget http://curl.haxx.se/download/curl-7.36.0.tar.gz
3. tar -xvzf curl-7.36.0.tar.gz
4. rm *.gz
5. cd curl-7.6.0
6. ./configure
7. make
8. make install

And restart Apache. If you will have an error during point 6, try to run apt-get install build-essential.

When a float is passed to printf, it is automatically converted to a double. This is part of the default argument promotions, which apply to functions that have a variable parameter list (containing ...), largely for historical reasons. Therefore, the “natural” specifier for a float, %f, must work with a double argument. So the %f and %lf specifiers for printf are the same; they both take a double value.

When scanf is called, pointers are passed, not direct values. A pointer to float is not converted to a pointer to double (this could not work since the pointed-to object cannot change when you change the pointer type). So, for scanf, the argument for %f must be a pointer to float, and the argument for %lf must be a pointer to double.

Having the right CSS and JS libraries helps, this solved it for me

Here's a solution that moves the directives that need to be added dynamically, into the view and also adds some optional (basic) conditional-logic. This keeps the directive clean with no hard-coded logic.

The directive takes an array of objects, each object contains the name of the directive to be added and the value to pass to it (if any).

I was struggling to think of a use-case for a directive like this until I thought that it might be useful to add some conditional logic that only adds a directive based on some condition (though the answer below is still contrived). I added an optional if property that should contain a bool value, expression or function (e.g. defined in your controller) that determines if the directive should be added or not.

I'm also using attrs.$attr.dynamicDirectives to get the exact attribute declaration used to add the directive (e.g. data-dynamic-directive, dynamic-directive) without hard-coding string values to check for.

I had this same error but my problem was I had the following:

M2_HOME = C:\Program Files (x86)\Apache Software Foundation\apache-maven-2.2.1;

Which meant my PATH = %M2_HOME%\bin; (etc)

...became C:\Program Files (x86)\Apache Software Foundation\apache-maven-2.2.1;\bin

i.e. a semicolon was where it shouldn't be.

Which I discovered because Michael Ferry suggested using 'ECHO %PATH%' to see what the actual PATH output was.

Use git revert like so:

git revert <insert bad commit hash here>

git revert creates a new commit with the changes that are rolled back. git reset erases your git history instead of making a new commit.

The steps after are the same as any other commit.

you have parse that Json string using JSON.parse()

..
}).done(function(data){
    obj = JSON.parse(data);
    alert(obj.jobtitel);
});

I had the same issue today when running the ancient software Dundjinni, a mapping tool, on Windows 10. (Dundjinni requires a rather old installation of Java; I haven’t tried updating Java, for fear the programme will fail.) My method was to simply run Dundjinni in administrator mode. Here is how:

Click Start or press the Start key, navigate down to the software, rightclick the programme, choose More, then choose Run as administrator. Note that this option is not available if you simply type the name of the software.

var obj = {name: 'Krishna', gender: 'male'};
angular.forEach(obj, function(value, key) {
    console.log(key + ': ' + value);
});

yields the attributes of obj with their respective values:

name: Krishna
gender: male

You must add an id that auto-increment for each row, after that you can delet the row by its id. so your table will have an unique id for each row and the id_user, id_product ecc...

This works using java.util.Scanner and will take multiple "enter" keystrokes:

    Scanner scanner = new Scanner(System.in);
    String readString = scanner.nextLine();
    while(readString!=null) {
        System.out.println(readString);

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }
    }

To break it down:

Scanner scanner = new Scanner(System.in);
String readString = scanner.nextLine();

These lines initialize a new Scanner that is reading from the standard input stream (the keyboard) and reads a single line from it.

    while(readString!=null) {
        System.out.println(readString);

While the scanner is still returning non-null data, print each line to the screen.

        if (readString.isEmpty()) {
            System.out.println("Read Enter Key.");
        }

If the "enter" (or return, or whatever) key is supplied by the input, the nextLine() method will return an empty string; by checking to see if the string is empty, we can determine whether that key was pressed. Here the text Read Enter Key is printed, but you could perform whatever action you want here.

        if (scanner.hasNextLine()) {
            readString = scanner.nextLine();
        } else {
            readString = null;
        }

Finally, after printing the content and/or doing something when the "enter" key is pressed, we check to see if the scanner has another line; for the standard input stream, this method will "block" until either the stream is closed, the execution of the program ends, or further input is supplied.

socket.disconnect() is a synonym to socket.close() which disconnect the socket manually.

When you type in client side :

const socket = io('http://localhost');

this will open a connection with autoConnect: true , so the lib will try to reconnect again when you disconnect the socket from server, to disable the autoConnection:

const socket = io('http://localhost', {autoConnect: false});
socket.open();// synonym to socket.connect()

And if you want you can manually reconnect:

socket.on('disconnect', () => {
  socket.open();
});

If anyone wonders for the Array version, it goes like this:

int i = Array.FindIndex(yourArray, x => x == itemYouWant);

Not a barplot solution but using lattice and barchart:

library(lattice)
barchart(Species~Reason,data=Reasonstats,groups=Catergory, 
         scales=list(x=list(rot=90,cex=0.8)))

Probably way too late but this is another option:

 $('body').popover({
    selector: '[rel=popover]',
    trigger: 'hover',
    html: true,
    content: function () {
        return $(this).parents('.row').first().find('.metaContainer').html();
    }
});

You can use ack. It is like grep for source code. You can scan your entire file system with it.

Just do:

ack 'text-to-find-here'

In your root directory.

You can also use regular expressions, specify the filetype, etc.

UPDATE

I just discovered The Silver Searcher, which is like ack but 3-5x faster than it and even ignores patterns from a .gitignore file.

Here's a data.table solution that will list the duplicates along with the number of duplications (will be 1 if there are 2 copies, and so on - you can adjust that to suit your needs):

library(data.table)
dt = data.table(vocabulary)

dt[duplicated(id), cbind(.SD[1], number = .N), by = id]

I think using enumerate on the outer loop and using the index to slice the list on the inner loop is pretty Pythonic:

for index, this in enumerate(mylist):
    for that in mylist[index+1:]:
        compare(this, that)

Most probably its because the B objects are not referring to the same Java C object instance. They are referring to the same row in the database (i.e. the same primary key) but they're different copies of it.

So what is happening is that the Hibernate session, which is managing the entities would be keeping track of which Java object corresponds to the row with the same primary key.

One option would be to make sure that the Entities of objects B that refer to the same row are actually referring to the same object instance of C. Alternatively turn off cascading for that member variable. This way when B is persisted C is not. You will have to save C manually separately though. If C is a type/category table, then it probably makes sense to be that way.

$('input[type="submit"]').click(function(){
$(this).css('color','red');
});

Use class, Demo:- http://jsfiddle.net/BX6Df/

   $('input[type="submit"]').click(function(){
          $(this).addClass('red');
});

if you want to toggle the color each click, you can try this:- http://jsfiddle.net/SMNks/

$('input[type="submit"]').click(function(){
  $(this).toggleClass('red');
});


.red
{
    background-color:red;
}

Updated answer for your comment.

$('input[type="submit"]').click(function(){
    $('input[type="submit"].red').removeClass('red')
        $(this).addClass('red');
});

>>> l = [19, 1, 2, 3, 4, 20, 20]

Although side_effect can achieve the goal, it is not so convenient to setup side_effect function for each test case.

I write a lightweight Mock (which is called NextMock) to enhance the built-in mock to address this problem, here is a simple example:

from nextmock import Mock

m = Mock()

m.with_args(1, 2, 3).returns(123)

assert m(1, 2, 3) == 123
assert m(3, 2, 1) != 123

It also supports argument matcher:

from nextmock import Arg, Mock

m = Mock()

m.with_args(1, 2, Arg.Any).returns(123)

assert m(1, 2, 1) == 123
assert m(1, 2, "123") == 123

Hope this package could make testing more pleasant. Feel free to give any feedback.

Dictionaries are specifically designed to do super fast key lookups. They are implemented as hashtables and the more entries the faster they are relative to other methods. Using the exception engine is only supposed to be done when your method has failed to do what you designed it to do because it is a large set of object that give you a lot of functionality for handling errors. I built an entire library class once with everything surrounded by try catch blocks once and was appalled to see the debug output which contained a seperate line for every single one of over 600 exceptions!

There are several problems here, so I'll start with my usual high-level advice: Start small and simple, add complexity a little at a time, test at every step, and never add to code that doesn't work. (I really ought to have that hotkeyed.)

You're mixing Make syntax and shell syntax in a way that is just dizzying. You should never have let it get this big without testing. Let's start from the outside and work inward.

UNAME := $(shell uname -m)

all:
    $(info Checking if custom header is needed)
    ifeq ($(UNAME), x86_64)
    ... do some things to build unistd_32.h
    endif

    @make -C $(KDIR) M=$(PWD) modules

So you want unistd_32.h built (maybe) before you invoke the second make, you can make it a prerequisite. And since you want that only in a certain case, you can put it in a conditional:

ifeq ($(UNAME), x86_64)
all: unistd_32.h
endif

all:
    @make -C $(KDIR) M=$(PWD) modules

unistd_32.h:
    ... do some things to build unistd_32.h

Now for building unistd_32.h:

F1_EXISTS=$(shell [ -e /usr/include/asm/unistd_32.h ] && echo 1 || echo 0 )
ifeq ($(F1_EXISTS), 1)
    $(info Copying custom header)
    $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm/unistd_32.h > unistd_32.h)
else    
    F2_EXISTS=$(shell [[ -e /usr/include/asm-i386/unistd.h ]] && echo 1 || echo 0 )
    ifeq ($(F2_EXISTS), 1)
        $(info Copying custom header)
        $(shell sed -e 's/__NR_/__NR32_/g' /usr/include/asm-i386/unistd.h > unistd_32.h)
    else
        $(error asm/unistd_32.h and asm-386/unistd.h does not exist)
    endif
endif

You are trying to build unistd.h from unistd_32.h; the only trick is that unistd_32.h could be in either of two places. The simplest way to clean this up is to use a vpath directive:

vpath unistd.h /usr/include/asm /usr/include/asm-i386

unistd_32.h: unistd.h
    sed -e 's/__NR_/__NR32_/g' $< > $@

This can also be done in the GUI:

1. Under the table "Person", right click Indexes
2. Click/hover New Index
3. Click Non-Clustered Index...

4. A default Index name will be given but you may want to change it.
5. Check Unique checkbox
6. Click Add... button

7. Check the columns you want included

8. Click OK in each window.

Just want to add one more case when controller can init twice (this is actual for angular.js 1.3.1):

<div ng-if="loading">Loading...</div>
<div ng-if="!loading">
    <div ng-view></div>
</div>

In this case $route.current will be already set when ng-view will init. That cause double initialization.

To fix it just change ng-if to ng-show/ng-hide and all will work well.

Set the data as a vector and then place in the function.

foreach over a statement is just a syntax sugar for the regular one-way fetch() loop. If you want to loop over your data more than once, select it as a regular array first

$sql = "SELECT * FROM users";
$stm = $dbh->query($sql);
// here you go:
$users = $stm->fetchAll();

foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}
echo "<br/>";
foreach ($users as $row) {
    print $row["name"] . "-" . $row["sex"] ."<br/>";
}

Also quit that try..catch thing. Don't use it, but set the proper error reporting for PHP and PDO

final FragmentTransaction ft = getFragmentManager().beginTransaction();
ft.hide(currentFragment);
ft.add(R.id.content_frame, newFragment.newInstance(context), "Profile");
ft.addToBackStack(null);
ft.commit();

an Event will fire multiple time when it is registered multiple times (even if to the same handler).

eg $("ctrl").on('click', somefunction) if this piece of code is executed every time the page is partially refreshed, the event is being registered each time too. Hence even if the ctrl is clicked only once it may execute "somefunction" multiple times - how many times it execute will depend on how many times it was registered.

this is true for any event registered in javascript.

solution:

ensure to call "on" only once.

and for some reason if you cannot control the architecture then do this:

$("ctrl").off('click'); $("ctrl").on('click', somefunction);

When you allocate memory for struct Vector you just allocate memory for pointer x, i.e. for space, where its value, which contains address, will be placed. So such way you do not allocate memory for the block, on which y.x will reference.

Use event delegation by assigning the onclick to the <ol>. Then pass the event object as the argument, and using that, grab the text from the clicked element.

function addText(event) {_x000D_
    var targ = event.target || event.srcElement;_x000D_
    document.getElementById("alltext").value += targ.textContent || targ.innerText;_x000D_
}

<textarea id="alltext"></textarea>_x000D_
_x000D_
<ol onclick="addText(event)">_x000D_
  <li>Hello</li>_x000D_
  <li>World</li>_x000D_
  <li>Earthlings</li>_x000D_
</ol>

Note that this method of passing the event object works in older IE as well as W3 compliant systems.

To create a popup you'll need the following script:

<script language="javascript" type="text/javascript">

function popitup(url) {
newwindow=window.open(url,'name','height=200,width=150');
if (window.focus) {newwindow.focus()}
return false;
}


</script>

Then, you link to it by:

  <a href="popupex.html" onclick="return popitup('popupex.html')">Link to popup</a>

If you want you can call the function directly from document.ready also. Or maybe from another function.

To 1): Yes, on most CPUs, SHA-256 is about only 40% as fast as MD5.

To 2): I would argue for a different algorithm than MD5 in such a case. I would definitely prefer an algorithm that is considered safe. However, this is more a feeling. Cases where this matters would be rather constructed than realistic, e.g. if your backup system encounters an example case of an attack on an MD5-based certificate, you are likely to have two files in such an example with different data, but identical MD5 checksums. For the rest of the cases, it doesn't matter, because MD5 checksums have a collision (= same checksums for different data) virtually only when provoked intentionally. I'm not an expert on the various hashing (checksum generating) algorithms, so I can not suggest another algorithm. Hence this part of the question is still open. Suggested further reading is Cryptographic Hash Function - File or Data Identifier on Wikipedia. Also further down on that page there is a list of cryptographic hash algorithms.

To 3): MD5 is an algorithm to calculate checksums. A checksum calculated using this algorithm is then called an MD5 checksum.

An alternative way would be to create a new temporary table with same structure.

CREATE TABLE temp_table AS SELECT * FROM original_table LIMIT 0

Then create the primary key in the table.

ALTER TABLE temp_table ADD PRIMARY KEY (primary-key-field)

Finally copy all records from the original table while ignoring the duplicate records.

INSERT IGNORE INTO temp_table AS SELECT * FROM original_table

Now you can delete the original table and rename the new table.

DROP TABLE original_table
RENAME TABLE temp_table TO original_table

You can find so many different sorting algorithms in internet, but if you want to fix your own solution you can do following changes in your code:

Instead of:

 orderedNums[greater]=tenNums[indexL];

you need to do this:

while (orderedNums[greater] == tenNums[indexL]) {
     greater++;
}
orderedNums[greater] = tenNums[indexL];

This code basically checks if that particular index is occupied by a similar number, then it will try to find next free index.

Note: Since the default value in your sorted array elements is 0, you need to make sure 0 is not in your list. otherwise you need to initiate your sorted array with an especial number that you sure is not in your list e.g: Integer.MAX_VALUE

I tried this code to find out if a customer is logged in or anonymous. I did using the th:if and th:unless conditional expressions. Pretty simple way to do it.

<!-- IF CUSTOMER IS ANONYMOUS -->
<div th:if="${customer.anonymous}">
   <div>Welcome, Guest</div>
</div>
<!-- ELSE -->
<div th:unless="${customer.anonymous}">
   <div th:text=" 'Hi,' + ${customer.name}">Hi, User</div>
</div>

The following code is in plain c language and handles blank spaces. It only allocates memory once, so one free() is needed, for each processed line.

In Visual Studio:

Tools -> Options -> Debugging -> Symbols

Choose "Only specified modules". Click the "specify modules" link, and add a blank module (click the new document button and hit OK).

First of all, you shouldn't rebuild all your views to fit a new screen, nor use different views for different screen sizes.

Use the auto-resizing capabilities of iOS, so your views can adjust, and adapt any screen size.

That's not very hard, read some documentation about that. It will save you a lot of time.

iOS 6 also offers new features about this.
Be sure to read the iOS 6 API changelog on Apple Developer website.
And check the new iOS 6 AutoLayout capabilities.

That said, if you really need to detect the iPhone 5, you can simply rely on the screen size.

[ [ UIScreen mainScreen ] bounds ].size.height

The iPhone 5's screen has a height of 568.
You can imagine a macro, to simplify all of this:

#define IS_IPHONE_5 ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )568 ) < DBL_EPSILON )

The use of fabs with the epsilon is here to prevent precision errors, when comparing floating points, as pointed in the comments by H2CO3.

So from now on you can use it in standard if/else statements:

if( IS_IPHONE_5 )
{}
else
{}

Edit - Better detection

As stated by some people, this does only detect a widescreen, not an actual iPhone 5.

Next versions of the iPod touch will maybe also have such a screen, so we may use another set of macros.

Let's rename the original macro IS_WIDESCREEN:

#define IS_WIDESCREEN ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )568 ) < DBL_EPSILON )

And let's add model detection macros:

#define IS_IPHONE ( [ [ [ UIDevice currentDevice ] model ] isEqualToString: @"iPhone" ] )
#define IS_IPOD   ( [ [ [ UIDevice currentDevice ] model ] isEqualToString: @"iPod touch" ] )

This way, we can ensure we have an iPhone model AND a widescreen, and we can redefine the IS_IPHONE_5 macro:

#define IS_IPHONE_5 ( IS_IPHONE && IS_WIDESCREEN )

Also note that, as stated by @LearnCocos2D, this macros won't work if the application is not optimised for the iPhone 5 screen (missing the [email protected] image), as the screen size will still be 320x480 in such a case.

I don't think this may be an issue, as I don't see why we would want to detect an iPhone 5 in a non-optimized app.

IMPORTANT - iOS 8 support

On iOS 8, the bounds property of the UIScreen class now reflects the device orientation.
So obviously, the previous code won't work out of the box.

In order to fix this, you can simply use the new nativeBounds property, instead of bounds, as it won't change with the orientation, and as it's based on a portrait-up mode.
Note that dimensions of nativeBounds is measured in pixels, so for an iPhone 5 the height will be 1136 instead of 568.

If you're also targeting iOS 7 or lower, be sure to use feature detection, as calling nativeBounds prior to iOS 8 will crash your app:

if( [ [ UIScreen mainScreen ] respondsToSelector: @selector( nativeBounds ) ] )
{
    /* Detect using nativeBounds - iOS 8 and greater */
}
else
{
    /* Detect using bounds - iOS 7 and lower */
}

You can adapt the previous macros the following way:

#define IS_WIDESCREEN_IOS7 ( fabs( ( double )[ [ UIScreen mainScreen ] bounds ].size.height - ( double )568 ) < DBL_EPSILON )
#define IS_WIDESCREEN_IOS8 ( fabs( ( double )[ [ UIScreen mainScreen ] nativeBounds ].size.height - ( double )1136 ) < DBL_EPSILON )
#define IS_WIDESCREEN      ( ( [ [ UIScreen mainScreen ] respondsToSelector: @selector( nativeBounds ) ] ) ? IS_WIDESCREEN_IOS8 : IS_WIDESCREEN_IOS7 )

And obviously, if you need to detect an iPhone 6 or 6 Plus, use the corresponding screen sizes.

In addition to the above great answers using Threads, in case you have to use your main thread or prefer an async approach - I wrapped a short class around aio_timers Timer class (to enable repeating)

import asyncio
from aio_timers import Timer

class RepeatingAsyncTimer():
    def __init__(self, interval, cb, *args, **kwargs):
        self.interval = interval
        self.cb = cb
        self.args = args
        self.kwargs = kwargs
        self.aio_timer = None
        self.start_timer()
    
    def start_timer(self):
        self.aio_timer = Timer(delay=self.interval, 
                               callback=self.cb_wrapper, 
                               callback_args=self.args, 
                               callback_kwargs=self.kwargs
                              )
    
    def cb_wrapper(self, *args, **kwargs):
        self.cb(*args, **kwargs)
        self.start_timer()


from time import time
def cb(timer_name):
    print(timer_name, time())

print(f'clock starts at: {time()}')
timer_1 = RepeatingAsyncTimer(interval=5, cb=cb, timer_name='timer_1')
timer_2 = RepeatingAsyncTimer(interval=10, cb=cb, timer_name='timer_2')

clock starts at: 1602438840.9690785

timer_1 1602438845.980087

timer_2 1602438850.9806316

timer_1 1602438850.9808934

timer_1 1602438855.9863033

timer_2 1602438860.9868324

timer_1 1602438860.9876585

For the second part of your question, you can also use shift, for example:

df['t-1'] = df['t'].shift(1)

t-1 would then contain the values from t one row above.

http://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.shift.html

This is called Double checked locking mechanism, first, we will check whether the instance is created or not. If not then only we will synchronize the method and create the instance. It will drastically improve the performance of the application. Performing lock is heavy. So to avoid the lock first we need to check the null value. This is also thread safe and it is the best way to achieve the best performance. Please have a look at the following code.

public sealed class Singleton
{
    private static readonly object Instancelock = new object();
    private Singleton()
    {
    }
    private static Singleton instance = null;

    public static Singleton GetInstance
    {
        get
        {
            if (instance == null)
            {
                lock (Instancelock)
                {
                    if (instance == null)
                    {
                        instance = new Singleton();
                    }
                }
            }
            return instance;
        }
    }
}

To stop the Media Player without the risk of an Illegal State Exception, you must do

  try {
        mp.reset();
        mp.prepare();
        mp.stop();
        mp.release();
        mp=null;
       }
  catch (Exception e)
         {
           e.printStackTrace();
         }

rather than just

try {
       mp.stop();
       mp.release();
       mp=null;
    } 
catch (Exception e) 
    {
      e.printStackTrace();
    }

If you have something else altering the DB (say another process) and need to ensure you see these changes, use AsNoTracking(), otherwise EF may give you the last copy that your context had instead, hence it being good to usually use a new context every query:

An "incomplete class" is one declared but not defined. E.g.

class Wielrenner;

as opposed to

class Wielrenner
{
    /* class members */
};

You need to #include "wielrenner.h" in dokter.ccp

Semi-related, but this is for initializing one unique event listener specific per element.

You can use the slider to show the values in realtime, or check the console. On the <input> element I have a attr tag called data-whatever, so you can customize that data if you want to.

sliders = document.querySelectorAll("input");_x000D_
sliders.forEach(item=> {_x000D_
  item.addEventListener('input', (e) => {_x000D_
    console.log(`${item.getAttribute("data-whatever")} is this value: ${e.target.value}`);_x000D_
    item.nextElementSibling.textContent = e.target.value;_x000D_
  });_x000D_
})

.wrapper {_x000D_
  display: flex;_x000D_
}_x000D_
span {_x000D_
  padding-right: 30px;_x000D_
  margin-left: 5px;_x000D_
}_x000D_
* {_x000D_
  font-size: 12px_x000D_
}

<div class="wrapper">_x000D_
  <input type="range" min="1" data-whatever="size" max="800" value="50" id="sliderSize">_x000D_
  <em>50</em>_x000D_
  <span>Size</span>_x000D_
  <br>_x000D_
  <input type="range" min="1" data-whatever="OriginY" max="800" value="50" id="sliderOriginY">_x000D_
  <em>50</em>_x000D_
  <span>OriginY</span>_x000D_
  <br>_x000D_
  <input type="range" min="1" data-whatever="OriginX" max="800" value="50" id="sliderOriginX">_x000D_
  <em>50</em>_x000D_
  <span>OriginX</span>_x000D_
</div>

Give your image an id. Then you can do this in your javascript.

document.getElementById("blaah").src="blaah";

You can use the ".___" method to change the value of any attribute of any element.

On Windows the easiest way is to use the program portecle.

1. Download and install portecle.
2. First make 100% sure you know which JRE or JDK is being used to run your program. On a 64 bit Windows 7 there could be quite a few JREs. Process Explorer can help you with this or you can use: System.out.println(System.getProperty("java.home"));
3. Copy the file JAVA_HOME\lib\security\cacerts to another folder.
4. In Portecle click File > Open Keystore File
5. Select the cacerts file
6. Enter this password: changeit
7. Click Tools > Import Trusted Certificate
8. Browse for the file mycertificate.pem
9. Click Import
10. Click OK for the warning about the trust path.
11. Click OK when it displays the details about the certificate.
12. Click Yes to accept the certificate as trusted.
13. When it asks for an alias click OK and click OK again when it says it has imported the certificate.
14. Click save. Don’t forget this or the change is discarded.
15. Copy the file cacerts back where you found it.

On Linux:

You can download the SSL certificate from a web server that is already using it like this:

$ echo -n | openssl s_client -connect www.example.com:443 | \
   sed -ne '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/examplecert.crt

Optionally verify the certificate information:

$ openssl x509 -in /tmp/examplecert.crt -text

Import the certificate into the Java cacerts keystore:

$ keytool -import -trustcacerts -keystore /opt/java/jre/lib/security/cacerts \
   -storepass changeit -noprompt -alias mycert -file /tmp/examplecert.crt

I have also faced the same issue, The solution for it is : the file for which you are getting the error is probably a duplicated file of the actual file with another version. So just the removal of a particular file on which errors are thrown can resolve the issue.

This is a huge topic, with answers from 3 lines of code to entire research magazines.

I will outline the most common such techniques and their results.

Comparing histograms

One of the simplest & fastest methods. Proposed decades ago as a means to find picture simmilarities. The idea is that a forest will have a lot of green, and a human face a lot of pink, or whatever. So, if you compare two pictures with forests, you'll get some simmilarity between histograms, because you have a lot of green in both.

Downside: it is too simplistic. A banana and a beach will look the same, as both are yellow.

OpenCV method: compareHist()

Template matching

A good example here matchTemplate finding good match. It convolves the search image with the one being search into. It is usually used to find smaller image parts in a bigger one.

Downsides: It only returns good results with identical images, same size & orientation.

OpenCV method: matchTemplate()

Feature matching

Considered one of the most efficient ways to do image search. A number of features are extracted from an image, in a way that guarantees the same features will be recognized again even when rotated, scaled or skewed. The features extracted this way can be matched against other image feature sets. Another image that has a high proportion of the features matching the first one is considered to be depicting the same scene.

Finding the homography between the two sets of points will allow you to also find the relative difference in shooting angle between the original pictures or the amount of overlapping.

There are a number of OpenCV tutorials/samples on this, and a nice video here. A whole OpenCV module (features2d) is dedicated to it.

Downsides: It may be slow. It is not perfect.

Over on the OpenCV Q&A site I am talking about the difference between feature descriptors, which are great when comparing whole images and texture descriptors, which are used to identify objects like human faces or cars in an image.

As @Renan mentioned, ng-include creates a new child scope. This scope prototypically inherits (see dashed lines below) from the HomeCtrl scope. ng-model="lineText" actually creates a primitive scope property on the child scope, not HomeCtrl's scope. This child scope is not accessible to the parent/HomeCtrl scope:

To store what the user typed into HomeCtrl's $scope.lines array, I suggest you pass the value to the addLine function:

 <form ng-submit="addLine(lineText)">

In addition, since lineText is owned by the ngInclude scope/partial, I feel it should be responsible for clearing it:

 <form ng-submit="addLine(lineText); lineText=''">

Function addLine() would thus become:

$scope.addLine = function(lineText) {
    $scope.chat.addLine(lineText);
    $scope.lines.push({
        text: lineText
    });
};

Fiddle.

Alternatives:

• define an object property on HomeCtrl's $scope, and use that in the partial: ng-model="someObj.lineText; fiddle
• not recommended, this is more of a hack: use $parent in the partial to create/access a lineText property on the HomeCtrl $scope:  ng-model="$parent.lineText"; fiddle

It is a bit involved to explain why the above two alternatives work, but it is fully explained here: What are the nuances of scope prototypal / prototypical inheritance in AngularJS?

I don't recommend using this in the addLine() function. It becomes much less clear which scope is being accessed/manipulated.

You can't reference an alias except in ORDER BY because SELECT is the second last clause that's evaluated. Two workarounds:

SELECT BalanceDue FROM (
  SELECT (InvoiceTotal - PaymentTotal - CreditTotal) AS BalanceDue
  FROM Invoices
) AS x
WHERE BalanceDue > 0;

Or just repeat the expression:

SELECT (InvoiceTotal - PaymentTotal - CreditTotal) AS BalanceDue
FROM Invoices
WHERE  (InvoiceTotal - PaymentTotal - CreditTotal)  > 0;

I prefer the latter. If the expression is extremely complex (or costly to calculate) you should probably consider a computed column (and perhaps persisted) instead, especially if a lot of queries refer to this same expression.

PS your fears seem unfounded. In this simple example at least, SQL Server is smart enough to only perform the calculation once, even though you've referenced it twice. Go ahead and compare the plans; you'll see they're identical. If you have a more complex case where you see the expression evaluated multiple times, please post the more complex query and the plans.

Here are 5 example queries that all yield the exact same execution plan:

SELECT LEN(name) + column_id AS x
FROM sys.all_columns
WHERE LEN(name) + column_id > 30;

SELECT x FROM (
SELECT LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE x > 30;

SELECT LEN(name) + column_id AS x
FROM sys.all_columns
WHERE column_id + LEN(name) > 30;

SELECT name, column_id, x FROM (
SELECT name, column_id, LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE x > 30;

SELECT name, column_id, x FROM (
SELECT name, column_id, LEN(name) + column_id AS x
FROM sys.all_columns
) AS x
WHERE LEN(name) + column_id > 30;

Resulting plan for all five queries:

It looks to me like it's because you are instantiating your TabListener every time... so the system is recreating your fragment from the savedInstanceState and then you are doing it again in your onCreate.

You should wrap that in a if(savedInstanceState == null) so it only fires if there is no savedInstanceState.

I think you could experiment with different activity flags, as it sounds like multiple instances.

"singleTop" "singleTask" "singleInstance"

Are the ones I would try, they can be defined inside the manifest.

http://developer.android.com/guide/topics/manifest/activity-element.html

From High Performance Android Apps book (page 157):

• what we see is equivalent of adb shell dumpsys cpuinfo command
• Numbers are showing CPU load over 1 minute, 5 minutes and 15 minutes (from the left)
• Colors are showing time spent by CPU in user space (green), kernel (red) and IO interrupt (blue)

Based on my testing, the correct flag is "allowMultiQueries=true"

Try disabling iptables: service iptables stop

If this works, enable TCP port 80 to your firewall rules: run system-config-selinux from root, and enable TCP port 80 (HTTP) on your firewall.

Add div wrapper

<div id=myForm>
<select name=countries>
 <option value=af>Afghanistan</option>
 <option value=ax>Åland Islands</option>
 ...
 <option value=gs>South Georgia and the South Sandwich Islands</option>
 ...
</select>
</div>

and then write CSS

#myForm select { 
width:200px; }

#myForm select:focus {
width:auto; }

Hope this will help.

There is one interesting option in this scenario I haven`t found in answers here.

You can Nack messages with "requeue" feature in one consumer to process them in another. Generally speaking it is not a right way, but maybe it will be good enough for someone.

https://www.rabbitmq.com/nack.html

And beware of loops (when all concumers nack+requeue message)!

It issue can be sorted by using, No need to set editText inputType to any values, just add the below line, editText.setTextIsSelectable(true);

While there does not appear to be a public, Facebook-curated list of error codes available, a number of folks have taken it upon themselves to publish lists of known codes.

Take a look at StackOverflow #4348018 - List of Facebook error codes for a number of useful resources.

There is a simpler way in Android

 DateFormat.getInstance().format(currentTimeMillis);

Moreover, Date is deprecated, so use DateFormat class.

   DateFormat.getDateInstance().format(new Date(0));  
   DateFormat.getDateTimeInstance().format(new Date(0));  
   DateFormat.getTimeInstance().format(new Date(0));  

The above three lines will give:

Dec 31, 1969  
Dec 31, 1969 4:00:00 PM  
4:00:00 PM  12:00:00 AM

You could use Guava Ranges

You can get a SortedSet by using

ImmutableSortedSet<Integer> set = Ranges.open(1, 5).asSet(DiscreteDomains.integers());
// set contains [2, 3, 4]

Try this one:

$('body').tooltip({
    selector: '[rel=tooltip]'
});

Depending on where the InputStream is coming from, you might not be able to reset it. You can check if mark() and reset() are supported using markSupported().

If it is, you can call reset() on the InputStream to return to the beginning. If not, you need to read the InputStream from the source again.

Don't name your current python script with the name of some other module you import

Solution: rename your working python script

Example:

1. you are working in medicaltorch.py
2. in that script, you have: from medicaltorch import datasets as mt_datasets where medicaltorch is supposed to be an installed module

This will fail with the ImportError. Just rename your working python script in 1.

Try underscore-cli:

cat myfile.json | underscore print --color

It's a pretty nifty tool that can elegantly do a lot of manipulation of structured data, execute js snippets, fill templates, etc. It's ridiculously well documented, polished, and ready for serious use. And I wrote it. :)

I would:

for _ in range(3):
    do()

The _ is convention for a variable whose value you don't care about.

You might also see some people write:

[do() for _ in range(3)]

however that is slightly more expensive because it creates a list containing the return values of each invocation of do() (even if it's None), and then throws away the resulting list. I wouldn't suggest using this unless you are using the list of return values.

Simple and not time consuming answer with an example relevant to the question asked Follow this example:

 user = [{"name": "Dough", "age": 55}, 
            {"name": "Ben", "age": 44}, 
            {"name": "Citrus", "age": 33},
            {"name": "Abdullah", "age":22},
            ]
    print(sorted(user, key=lambda el: el["name"]))
    print(sorted(user, key= lambda y: y["age"]))

Look at the names in the list, they starts with D, B, C and A. And if you notice the ages, they are 55, 44, 33 and 22. The first print code

print(sorted(user, key=lambda el: el["name"]))

Results to:

[{'name': 'Abdullah', 'age': 22}, 
{'name': 'Ben', 'age': 44}, 
{'name': 'Citrus', 'age': 33}, 
{'name': 'Dough', 'age': 55}]

sorts the name, because by key=lambda el: el["name"] we are sorting the names and the names return in alphabetical order.

The second print code

print(sorted(user, key= lambda y: y["age"]))

Result:

[{'name': 'Abdullah', 'age': 22},
 {'name': 'Citrus', 'age': 33},
 {'name': 'Ben', 'age': 44}, 
 {'name': 'Dough', 'age': 55}]

sorts by age, and hence the list returns by ascending order of age.

Try this code for better understanding.

onProgressChanged() should be called on every progress changed, not just on first and last touch (that why you have onStartTrackingTouch() and onStopTrackingTouch() methods).

Make sure that your SeekBar have more than 1 value, that is to say your MAX>=3.

In your onCreate:

 yourSeekBar=(SeekBar) findViewById(R.id.yourSeekBar);
 yourSeekBar.setOnSeekBarChangeListener(new yourListener());

Your listener:

private class yourListener implements SeekBar.OnSeekBarChangeListener {

        public void onProgressChanged(SeekBar seekBar, int progress,
                boolean fromUser) {
                            // Log the progress
            Log.d("DEBUG", "Progress is: "+progress);
                            //set textView's text
            yourTextView.setText(""+progress);
        }

        public void onStartTrackingTouch(SeekBar seekBar) {}

        public void onStopTrackingTouch(SeekBar seekBar) {}

    }

Paste this in your Main Activity and this will solve your issue

The issue is because you have a bean of type SuggestionService created through @Component annotation and also through the XML config . As explained by JB Nizet, this will lead to the creation of a bean with name 'suggestionService' created via @Component and another with name 'SuggestionService' created through XML .

When you refer SuggestionService by @Autowired, in your controller, Spring autowires "by type" by default and find two beans of type 'SuggestionService'

You could do the following

1. Remove @Component from your Service and depend on mapping via XML - Easiest

2. Remove SuggestionService from XML and autowire the dependencies - use util:map to inject the indexSearchers map.

3. Use @Resource instead of @Autowired to pick the bean by its name .

    @Resource(name="suggestionService")
    private SuggestionService service;
   

or

    @Resource(name="SuggestionService")
    private SuggestionService service;

both should work.The third is a dirty fix and it's best to resolve the bean conflict through other ways.

Bootstrap provide events that you can hook into modal, like if you want to fire a event when the modal has finished being hidden from the user you can use hidden.bs.modal event like this

    /* hidden.bs.modal event example */
    $('#myModal').on('hidden.bs.modal', function () {
          window.alert('hidden event fired!');
    })

From Django docs :

To handle both of these situations, Django has a consistent way of processing filter() calls. Everything inside a single filter() call is applied simultaneously to filter out items matching all those requirements. Successive filter() calls further restrict the set of objects, but for multi-valued relations, they apply to any object linked to the primary model, not necessarily those objects that were selected by an earlier filter() call.

• It is clearly said that multiple conditions in a single filter() are applied simultaneously. That means that doing :

objs = Mymodel.objects.filter(a=True, b=False)

will return a queryset with raws from model Mymodel where a=True AND b=False.

• Successive filter(), in some case, will provide the same result. Doing :

objs = Mymodel.objects.filter(a=True).filter(b=False)

will return a queryset with raws from model Mymodel where a=True AND b=False too. Since you obtain "first" a queryset with records which have a=True and then it's restricted to those who have b=False at the same time.

• The difference in chaining filter() comes when there are multi-valued relations, which means you are going through other models (such as the example given in the docs, between Blog and Entry models). It is said that in that case (...) they apply to any object linked to the primary model, not necessarily those objects that were selected by an earlier filter() call.

Which means that it applies the successives filter() on the target model directly, not on previous filter()

If I take the example from the docs :

Blog.objects.filter(entry__headline__contains='Lennon').filter(entry__pub_date__year=2008)

remember that it's the model Blog that is filtered, not the Entry. So it will treat the 2 filter() independently.

It will, for instance, return a queryset with Blogs, that have entries that contain 'Lennon' (even if they are not from 2008) and entries that are from 2008 (even if their headline does not contain 'Lennon')

THIS ANSWER goes even further in the explanation. And the original question is similar.

b = a[a>threshold] this should do

I tested as follows:

import numpy as np, datetime
# array of zeros and ones interleaved
lrg = np.arange(2).reshape((2,-1)).repeat(1000000,-1).flatten()

t0 = datetime.datetime.now()
flt = lrg[lrg==0]
print datetime.datetime.now() - t0

t0 = datetime.datetime.now()
flt = np.array(filter(lambda x:x==0, lrg))
print datetime.datetime.now() - t0

I got

$ python test.py

I'd a similar problem in a legacy application, but de "--" was string parameter.

Ex.:

Dim cmd As New OracleCommand("INSERT INTO USER (name, address, photo) VALUES ('User1', '--', :photo)", oracleConnection)
Dim fs As IO.FileStream = New IO.FileStream("c:\img.jpg", IO.FileMode.Open)
Dim br As New IO.BinaryReader(fs)
cmd.Parameters.Add(New OracleParameter("photo", OracleDbType.Blob)).Value = br.ReadBytes(fs.Length)
cmd.ExecuteNonQuery() 'here throws ORA-01008

Changing address parameter value '--' to '00' or other thing, works.

It is printing the statement twice because it is printing it for both the parent and the child. The parent has a parent id of 0

Try something like this:

 pid_t  pid;
 pid = fork();
 if (pid == 0) 
    printf("This is the child process. My pid is %d and my parent's id is %d.\n", getpid(),getppid());
 else 
    printf("This is the parent process. My pid is %d and my parent's id is %d.\n", getpid(), getppid() );

Using an Cursor FOR LOOP Statement is my favourite way to do this.

It is safer than using an explicit cursor, because you don't need to remember to close it, so you can't "leak" cursors.

You don't need "into" variables, you don't need to "FETCH", you don't need to catch and handle "NO DATA FOUND" exceptions.

Try it, you'll never go back.

v_column my_table.column%TYPE;

v_column := null;

FOR rMyTable IN (SELECT COLUMN FROM MY_TABLE WHERE ....) LOOP
  v_column := rMyTable.COLUMN;
  EXIT;  -- Exit the loop if you only want the first result.
END LOOP;

The se argument from the example also isn't in the help or online documentation.

You can use this SpringBeanJobFactory to automatically autowire quartz objects using spring:

import org.quartz.spi.TriggerFiredBundle;
import org.springframework.beans.factory.config.AutowireCapableBeanFactory;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.scheduling.quartz.SpringBeanJobFactory;

public final class AutowiringSpringBeanJobFactory extends SpringBeanJobFactory implements
    ApplicationContextAware {

    private transient AutowireCapableBeanFactory beanFactory;

    @Override
    public void setApplicationContext(final ApplicationContext context) {
        beanFactory = context.getAutowireCapableBeanFactory();
    }

    @Override
    protected Object createJobInstance(final TriggerFiredBundle bundle) throws Exception {
        final Object job = super.createJobInstance(bundle);
        beanFactory.autowireBean(job);
        return job;
    }
}

Then, attach it to your SchedulerBean (in this case, with Java-config):

@Bean
public SchedulerFactoryBean quartzScheduler() {
    SchedulerFactoryBean quartzScheduler = new SchedulerFactoryBean();

    ...

    AutowiringSpringBeanJobFactory jobFactory = new AutowiringSpringBeanJobFactory();
    jobFactory.setApplicationContext(applicationContext);
    quartzScheduler.setJobFactory(jobFactory);

    ...

    return quartzScheduler;
}

Working for me, using spring-3.2.1 and quartz-2.1.6.

I finally found the problem. The error was not the good one.

Apparently, Ole DB source have a bug that might make it crash and throw that error. I replaced the OLE DB destination with a OLE DB Command with the insert statement in it and it fixed it.

The link the got me there: http://social.msdn.microsoft.com/Forums/en-US/sqlintegrationservices/thread/fab0e3bf-4adf-4f17-b9f6-7b7f9db6523c/

Strange Bug, Hope it will help other people.

It has been mentioned that Scala does have syntax for for loops:

for (i <- 0 until xs.length) ...

or simply

for (i <- xs.indices) ...

However, you also asked for efficiency. It turns out that the Scala for syntax is actually syntactic sugar for higher order methods such as map, foreach, etc. As such, in some cases these loops can be inefficient, e.g. How to optimize for-comprehensions and loops in Scala?

(The good news is that the Scala team is working on improving this. Here's the issue in the bug tracker: https://issues.scala-lang.org/browse/SI-4633)

For utmost efficiency, one can use a while loop or, if you insist on removing uses of var, tail recursion:

import scala.annotation.tailrec

@tailrec def printArray(i: Int, xs: Array[String]) {
  if (i < xs.length) {
    println("String #" + i + " is " + xs(i))
    printArray(i+1, xs)
  }
}
printArray(0, Array("first", "second", "third"))

Note that the optional @tailrec annotation is useful for ensuring that the method is actually tail recursive. The Scala compiler translates tail-recursive calls into the byte code equivalent of while loops.

Calling unbind solved my problem:

$("#btn").unbind("click").click(function() {
    // your code
});

max([(value,index) for index,value in enumerate(your_list)]) #if maximum value is present more than once in your list then this will return index of the last occurrence

If maximum value in present more than once and you want to get all indices,

max_value = max(your_list)
maxIndexList = [index for index,value in enumerate(your_list) if value==max(your_list)]

I've just checked and i have the same code as you and it works perferctly. The only difference is how i fill my List for the params :

I use a : ArrayList<BasicNameValuePair> params

and fill it this way :

 params.add(new BasicNameValuePair("apikey", apikey);

I do not use any JSONObject to send params to the webservices.

Are you obliged to use the JSONObject ?

Since Mockito 2.0 there's also possibility to use static method Matchers.argThat(ArgumentMatcher). With the help of Java 8 it is now much cleaner and more readable to write:

verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("OneSurname")));
verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("AnotherSurname")));

If you're tied to lower Java version there's also not-that-bad:

verify(mockBar).doSth(argThat(new ArgumentMatcher<Employee>() {
        @Override
        public boolean matches(Object emp) {
            return ((Employee) emp).getSurname().equals("SomeSurname");
        }
    }));

Of course none of those can verify order of calls - for which you should use InOrder :

InOrder inOrder = inOrder(mockBar);

inOrder.verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("FirstSurname")));
inOrder.verify(mockBar).doSth(argThat((arg) -> arg.getSurname().equals("SecondSurname")));

Please take a look at mockito-java8 project which makes possible to make calls such as:

verify(mockBar).doSth(assertArg(arg -> assertThat(arg.getSurname()).isEqualTo("Surname")));

git rebase origin means "rebase from the tracking branch of origin", while git rebase origin/master means "rebase from the branch master of origin"

You must have a tracking branch in ~/Desktop/test, which means that git rebase origin knows which branch of origin to rebase with. If no tracking branch exists (in the case of ~/Desktop/fallstudie), git doesn't know which branch of origin it must take, and fails.

To fix this, you can make the branch track origin/master with:

git branch --set-upstream-to=origin/master 

Or, if master isn't the currently checked-out branch:

git branch --set-upstream-to=origin/master master

You are calling setTimeout() ten times in a row, so they all expire almost at the same time. What you actually want is this:

window.onload = function start() {
    slide(10);
}
function slide(repeats) {
    if (repeats > 0) {
        document.getElementById('container').style.marginLeft='-600px';
        document.getElementById('container').style.marginLeft='-1200px';
        document.getElementById('container').style.marginLeft='-1800px';
        document.getElementById('container').style.marginLeft='0px';
        window.setTimeout(
          function(){
            slide(repeats - 1)
          },
          3000
        );
    }
}

This will call slide(10), which will then set the 3-second timeout to call slide(9), which will set timeout to call slide(8), etc. When slide(0) is called, no more timeouts will be set up.

I will show visually the problem, using the great example from James answer and adding the alternative solution.

When you do the follow query, without the FETCH:

Select e from Employee e 
join e.phones p 
where p.areaCode = '613'

You will have the follow results from Employee as you expected:

But when you add the FETCH word on JOIN, this is what happens:

The generated SQL is the same for the two queries, but the Hibernate removes on memory the 416 register when you use WHERE on the FETCH join.

So, to bring all phones and apply the WHERE correctly, you need to have two JOINs: one for the WHERE and another for the FETCH. Like:

Select e from Employee e 
join e.phones p 
join fetch e.phones      //no alias, to not commit the mistake
where p.areaCode = '613'

I'm using a similar code as those that use the while loop but I call the entry count in every loop... so I suppose it's somewhat slower

FragmentManager manager = getFragmentManager();
while (manager.getBackStackEntryCount() > 0){
        manager.popBackStackImmediate();
    }

Without code in iframe + animate:

<script src="https://ajax.googleapis.com/ajax/libs/jquery/3.1.0/jquery.min.js"></script>
<script language="javascript" type="text/javascript">

function resizeIframe(obj) {

    jQuery(document).ready(function($) {

        $(obj).animate({height: obj.contentWindow.document.body.scrollHeight + 'px'}, 500)

    });

}    
</script>
<iframe width="100%" src="iframe.html" height="0" frameborder="0" scrolling="no" onload="resizeIframe(this)" >

Not sure, but you should be able to do something by setting a default active profile in your settings.xml

See http://maven.apache.org/guides/introduction/introduction-to-profiles.html

Just do below code it's working absolute fine

$(".addproduct").on('click', function(event){
    event.stopPropagation();
    event.stopImmediatePropagation();
    getRecord();
});


function getRecord(){
   $(".addproduct").each(function () {
       console.log("test");
       });

}

No to compare anything, you can simply check that by this...,.

if(document.getElementById("url")){ alert('exit');}
if($("#url")){alert('exist');}

you can also use the html() function as well like

if($("#url).html()){alert('exist');}

Which is pretty damn good, to be fair.

Your syntax is not correct. It should be like that:

for (Tweet tweet : tweets) {              
    for(long forId : idFromArray){
        long tweetId = tweet.getId();
        if(forId != tweetId){
            String twitterString = tweet.getText();
            db.insertTwitter(twitterString);
        }
    }
}

EDIT

This answer no longer really answers the question since it was updated ;)

I've had success mutex-promise.

I agree with other answers that you might not need locking in your case. But it's not true that one never needs locking in Javascript. You need mutual exclusivity when accessing external resources that do not handle concurrency.

U can also use :

var query =
    from t1 in myTABLE1List 
    join t2 in myTABLE1List
      on new { ColA=t1.ColumnA, ColB=t1.ColumnB } equals new { ColA=t2.ColumnA, ColB=t2.ColumnB }
    join t3 in myTABLE1List
      on new {ColC=t2.ColumnA, ColD=t2.ColumnB } equals new { ColC=t3.ColumnA, ColD=t3.ColumnB }

It's an inlined image (png), encoded in base64. It can make a page faster: the browser doesn't have to query the server for the image data separately, saving a round trip.

(It can also make it slower if abused: these resources are not cached, so the bytes are included in each page load.)

Deleting Obj, retail and debug folder of the .NET project and re-building again worked for me.

I don't try to answer all of my questions, as I believe it is too broad. Just a couple of notes:

there are cases when object construction is a task complex enough to justify its extraction to another class.

That class is in fact a Builder, rather than a Factory.

In the general case, I don't want to force the users of the factory to be restrained to dynamic allocation.

Then you could have your factory encapsulate it in a smart pointer. I believe this way you can have your cake and eat it too.

This also eliminates the issues related to return-by-value.

Conclusion: Making a factory by returning an object is indeed a solution for some cases (such as the 2-D vector previously mentioned), but still not a general replacement for constructors.

Indeed. All design patterns have their (language specific) constraints and drawbacks. It is recommended to use them only when they help you solve your problem, not for their own sake.

If you are after the "perfect" factory implementation, well, good luck.

Javascript String objects have a split function, doesn't really need to be jQuery specific

 var str = "nice.test"
 var strs = str.split(".")

strs would be

 ["nice", "test"]

I'd be tempted to use JSON in your example though. The php could return the JSON which could easily be parsed

 success: function(data) {
   var items = JSON.parse(data)
 }

We had a situation where IE forced us to post as text/plain, so we had to manually parse the parameters using getReader. The servlet was being used for long polling, so when AsyncContext::dispatch was executed after a delay, it was literally reposting the request empty handed.

So I just stored the post in the request when it first appeared by using HttpServletRequest::setAttribute. The getReader method empties the buffer, where getParameter empties the buffer too but stores the parameters automagically.

    String input = null;

    // we have to store the string, which can only be read one time, because when the
    // servlet awakens an AsyncContext, it reposts the request and returns here empty handed
    if ((input = (String) request.getAttribute("com.xp.input")) == null) {
        StringBuilder buffer = new StringBuilder();
        BufferedReader reader = request.getReader();

        String line;
        while((line = reader.readLine()) != null){
            buffer.append(line);
        }
        // reqBytes = buffer.toString().getBytes();

        input = buffer.toString();
        request.setAttribute("com.xp.input", input);
    }

    if (input == null) {
        response.setContentType("text/plain");
        PrintWriter out = response.getWriter();
        out.print("{\"act\":\"fail\",\"msg\":\"invalid\"}");
    }       

XmlDocument doc = new XmlDocument();
doc.LoadXml(str);

Where str is your XML string. See the MSDN article for more info.

Considering this issue again: there is a very popular solution that is referenced within this thread that has its origin here:

DIR="$( cd "$( dirname "${BASH_SOURCE[0]}" )" && pwd )"

I have stayed away from this solution because of the use of dirname - it can present cross-platform difficulties, particularly if a script needs to be locked down for security reasons. But as a pure Bash alternative, how about using:

DIR="$( cd "$( echo "${BASH_SOURCE[0]%/*}" )" && pwd )"

Would this be an option?

Of all the answers, none considered the ridiculously easy fastcgi_finish_request function, that when called, flushes all remaining output to the browser and closes the Fastcgi session and the HTTP connection, while letting the script run in the background.

An example:

<?php
header('Content-Type: application/json');
echo json_encode(['ok' => true]);
fastcgi_finish_request(); // The user is now disconnected from the script

// do stuff with received data,

from is a keyword in SQL. You may not used it as a column name without quoting it. In MySQL, things like column names are quoted using backticks, i.e. `from`.

Personally, I wouldn't bother; I'd just rename the column.

PS. as pointed out in the comments, to is another SQL keyword so it needs to be quoted, too. Conveniently, the folks at drupal.org maintain a list of reserved words in SQL.

The web.xml file is the deployment descriptor for a Servlet-based Java web application (which most Java web apps are). Among other things, it declares which Servlets exist and which URLs they handle.

The part you cite defines a Servlet Filter. Servlet filters can do all kinds of preprocessing on requests. Your specific example is a filter had the Wicket framework uses as its entry point for all requests because filters are in some way more powerful than Servlets.

Adding an object in a json array

var arrList = [];
var arr = {};   
arr['worker_id'] = worker_id;
arr['worker_nm'] = worker_nm;
arrList.push(arr);

Removing an object from a json

It worker for me.

  arrList = $.grep(arrList, function (e) { 

        if(e.worker_id == worker_id) {
            return false;
        } else {
            return true;
        }
    });

It returns an array without that object.

Hope it helps.

Using:

  SELECT t.ctn_no
    FROM YOUR_TABLE t
GROUP BY t.ctn_no
  HAVING COUNT(t.ctn_no) > 1

...will show you the ctn_no value(s) that have duplicates in your table. Adding criteria to the WHERE will allow you to further tune what duplicates there are:

  SELECT t.ctn_no
    FROM YOUR_TABLE t
   WHERE t.s_ind = 'Y'
GROUP BY t.ctn_no
  HAVING COUNT(t.ctn_no) > 1

If you want to see the other column values associated with the duplicate, you'll want to use a self join:

SELECT x.*
  FROM YOUR_TABLE x
  JOIN (SELECT t.ctn_no
          FROM YOUR_TABLE t
      GROUP BY t.ctn_no
        HAVING COUNT(t.ctn_no) > 1) y ON y.ctn_no = x.ctn_no

The first is good unless either Phone1 or (more likely) phone2 can be null. In that case you want to use a Left join instead of an inner join.

It is usually a bad sign when you have a table with two phone number fields. Usually this means your database design is flawed.

I'm not sure if this is the most pythonic method ... I had a list of tuples that needed sorting 1st by descending integer values and 2nd alphabetically. This required reversing the integer sort but not the alphabetical sort. Here was my solution: (on the fly in an exam btw, I was not even aware you could 'nest' sorted functions)

a = [('Al', 2),('Bill', 1),('Carol', 2), ('Abel', 3), ('Zeke', 2), ('Chris', 1)]  
b = sorted(sorted(a, key = lambda x : x[0]), key = lambda x : x[1], reverse = True)  
print(b)  
[('Abel', 3), ('Al', 2), ('Carol', 2), ('Zeke', 2), ('Bill', 1), ('Chris', 1)]

For those moments when you really want to avoid building lists:

import re
import operator
from functools import reduce
count = reduce(operator.add, (1 for _ in re.finditer(my_pattern, my_string))) 

Sometimes you might need to operate on huge strings. This might help.

we have to give the controller name in lower cases in server side

$this->class = strtolower(__CLASS__);

Here is an idea: you calculate the (discrete) Laplacian of the image. I would expect it to be (negative and) large at maxima, in a way that is more dramatic than in the original images. Thus, maxima could be easier to find.

Here is another idea: if you know the typical size of the high-pressure spots, you can first smooth your image by convoluting it with a Gaussian of the same size. This may give you simpler images to process.

If I remember correctly (from a couple of years ago), one of the senior developers was talking about a fast way to bzero() on PowerPC (specs said we needed to zero almost all the memory on power up). It might not translate well (if at all) to x86, but it could be worth exploring.

The idea was to load a data cache line, clear that data cache line, and then write the cleared data cache line back to memory.

For what it is worth, I hope it helps.

Your quotes only need to surround the value part of the attribute-equals selector, [attr='val'], like this:

$('a#check_var').click(function() {
  alert($("input:radio[name='r']:checked").val()+ ' '+
        $("input:radio[name='s']:checked").val());
});?

You can see the working version here.

Actually you don't have to deal with the static metamodel if you had your annotations right.

  @ManyToOne
  protected Set<Owner> owners;
}

@Entity
public class Owner {
  @Id
  protected Long id;
  protected String name;
}

You can use this :

CriteriaQuery<Pet> cq = cb.createQuery(Pet.class);
Metamodel m = em.getMetamodel();
EntityType<Pet> petMetaModel = m.entity(Pet.class);

Root<Pet> pet = cq.from(Pet.class);
Join<Pet, Owner> owner = pet.join(petMetaModel.getSet("owners", Owner.class));

If you call methods in your constructor that subclasses override, it means you are less likely to be referencing variables that don’t exist yet if you divide your initialization logically between the constructor and the method.

Have a look on this sample link http://www.javapractices.com/topic/TopicAction.do?Id=215

It's easier if you get these values into a list of tuples. To do this, you can use list slicing and the zip function.

data_in = [2010,2,2009,4,1989,8,2009,7]
data_pairs = zip(data_in[::2],data_in[1::2])

Zip takes an arbitrary number of lists, in this case the even and odd entries of data_in, and puts them together into a tuple.

Now we can use the setdefault method.

data_dict = {}
for x in data_pairs:
    data_dict.setdefault(x[0],[]).append(x[1])

setdefault takes a key and a default value, and returns either associated value, or if there is no current value, the default value. In this case, we will either get an empty or populated list, which we then append the current value to.

I had the same problem and tried everything but it didn't worked. So I used following trick:

function do_stuff(e)
{
    if(e){ alert(e); }
}
$("#delete").click(function() {
    do_stuff("Clicked");
});

You check if that parameter isn't null than you do code. So when the function will triggered second time it will show what you want.

This is going to sound stupid, but I tried all these solutions, running VS2010 on Windows 7. None of them worked except the renaming and building, which was VERY tedious to say the least. Eventually, I tracked down the culprit, and I find it hard to believe. But I was using the following code in AssemblyInfo.cs...

[assembly: AssemblyVersion("2.0.*")]

This is pretty common, but for some reason, changing the version to 2.0.0.0 made things work again. I don't know if it's a Windows 7 specific thing (I've only been using it for 3-4 weeks), or if it's random, or what, but it fixed it for me. I'm guessing that VS was keeping a handle on each file it generated, so it would know how to increment things? I'm really not sure and have never seen this happen before. But if someone else out there is also pulling their hair out, give it a try.

fastest solution:

If you have python 3.4.x, the solution is simply to install VC++ 2010 since it is used to compile itself into.

https://www.visualstudio.com/en-us/downloads#d-2010-express

my python version is MSC v.1600 32 bit (intel)] on win32

worked fine on Windows8

After installing weblogic and forms server on a Linux machine we met some problems initializing sqlplus and tnsping. We altered the bash_profile in a way that the forms_home acts as the oracle home. It works fine, both commands (sqlplus and tnsping) are executable for user oracle

# .bash_profile

# Get the aliases and functions
if [ -f ~/.bashrc ]; then
    . ~/.bashrc
fi

# User specific environment and startup programs

PATH=$PATH:$HOME/bin

export JAVA_HOME=/mnt/software/java/jdk1.7.0_71
export ORACLE_HOME=/oracle/Middleware/Oracle_FRHome1
export PATH=$PATH:$JAVA_HOME/bin:$ORACLE_HOME/bin
export LD_LIBRARY_PATH=/oracle/Middleware/Oracle_FRHome1/lib
export FORMS_PATH=$FORMS_PATH:/oracle/Middleware/Oracle_FRHome1/forms:/oracle/Middleware/asinst_1/FormsComponent/forms:/appl/myapp:/home/oracle/myapp

First you need to input the two numbers say num_rows and num_columns perhaps using argc and argv then do a for loop to print the dots.

int j=0;
int k=0;
for (k=0;k<num_columns;k++){
   for (j=0;j<num_rows;j++){
       printf(".");
   }
 printf("\n");
 }

you'd have to replace the dot with something else later.

I found that following these instructions helped with finding what the problem was. For me, that was the killer, not knowing what was broken.

http://mythinkpond.wordpress.com/2011/07/01/tomcat-6-infamous-severe-error-listenerstart-message-how-to-debug-this-error/

Quoting from the link

In Tomcat 6 or above, the default logger is the”java.util.logging” logger and not Log4J. So if you are trying to add a “log4j.properties” file – this will NOT work. The Java utils logger looks for a file called “logging.properties” as stated here: http://tomcat.apache.org/tomcat-6.0-doc/logging.html

So to get to the debugging details create a “logging.properties” file under your”/WEB-INF/classes” folder of your WAR and you’re all set.

And now when you restart your Tomcat, you will see all of your debugging in it’s full glory!!!

Sample logging.properties file:

org.apache.catalina.core.ContainerBase.[Catalina].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].handlers = java.util.logging.ConsoleHandler

I have found a new workaround, different from any other that I have seen, by disabling the native iOS zoom, and instead implementing zoom functionality in JavaScript.

An excellent background on the various other solutions to the zoom/orientation problem is by Sérgio Lopes: A fix to the famous iOS zoom bug on orientation change to portrait.

It could be improved, but for my needs it avoids the major drawbacks that occur with all the other solutions I have seen. So far I have only tested it using mobile Safari on an iPad 2 with iOS4.

The focus()/blur() is a workaround to prevent the occasional lockup of the zoom functionality which can occur after changing orientation and zooming a few times.

Setting the document.body.style forces a full screen repaint, which avoids an occasional intermittent problems where the repaint badly fails after zoom.

This answer is actually taken from Scott Allen's course titled ASP.NET MVC 5 Fundamentals. I thought I'd share because I think it is slightly simpler and more intuitive than any of the answers here already. Also note according to Scott Allen and other trainings I've done, find method is an optimized way to retrieve a resource from database that can use caching if it already has been retrieved. In this code, collection refers to a DBSet of objects. Object can be any generic object type.

        var object = context.collection.Find(id);  
        context.collection.Remove(object);
        context.SaveChanges();

Once you have cloned the repo, you have everything: you can then hg up branchname or hg up tagname to update your working copy.

UP: hg up is a shortcut of hg update, which also has hg checkout alias for people with git habits.

No, CASE is a function, and can only return a single value. I think you are going to have to duplicate your CASE logic.

The other option would be to wrap the whole query with an IF and have two separate queries to return results. Without seeing the rest of the query, it's hard to say if that would work for you.

Not sure if Access supports it, but in most engines (including SQL Server) this is called a correlated subquery and works fine:

SELECT  TypesAndBread.Type, TypesAndBread.TBName,
        (
        SELECT  Count(Sandwiches.[SandwichID]) As SandwichCount
        FROM    Sandwiches
        WHERE   (Type = 'Sandwich Type' AND Sandwiches.Type = TypesAndBread.TBName)
                OR (Type = 'Bread' AND Sandwiches.Bread = TypesAndBread.TBName)
        ) As SandwichCount
FROM    TypesAndBread

This can be made more efficient by indexing Type and Bread and distributing the subqueries over the UNION:

SELECT  [Sandwiches Types].[Sandwich Type] As TBName, "Sandwich Type" As Type,
        (
        SELECT  COUNT(*) As SandwichCount
        FROM    Sandwiches
        WHERE   Sandwiches.Type = [Sandwiches Types].[Sandwich Type]
        )
FROM    [Sandwiches Types]
UNION ALL
SELECT  [Breads].[Bread] As TBName, "Bread" As Type,
        (
        SELECT  COUNT(*) As SandwichCount
        FROM    Sandwiches
        WHERE   Sandwiches.Bread = [Breads].[Bread]
        )
FROM    [Breads]

I have changed the way I monitor files in directories. Instead of using the FileSystemWatcher I poll locations on another thread and then look at the LastWriteTime of the file.

DateTime lastWriteTime = File.GetLastWriteTime(someFilePath);

Using this information and keeping an index of a file path and it's latest write time I can determine files that have changed or that have been created in a particular location. This removes me from the oddities of the FileSystemWatcher. The main downside is that you need a data structure to store the LastWriteTime and the reference to the file, but it is reliable and easy to implement.

After trying all solutions presented here and not being satisfied, I have found a script which is matching my needs and it is more user friendly. For the record, I will save it as a possible solution. I love the copy/paste solutions :)

Script returns a select with whatever timezone you want preselected.

In general, if you are using white-space: nowrap; it is probably because you know which columns are going to contain content which wraps (or stretches the cell). For those columns, I generally wrap the cell's contents in a span with a specific class attribute and apply a specific width.

Example:

HTML:

<td><span class="description">My really long description</span></td>

CSS:

span.description {
    display: inline-block;
    overflow: hidden;
    white-space: nowrap;
    width: 150px;
}

I ran into this page while wondering the same question.

As others have noted, it's simple enough to just grab the __name__ attribute from a function in order to determine the name of the function. It's marginally trickier with objects that don't have a sane way to determine __name__, i.e. base/primitive objects like basestring instances, ints, longs, etc.

Long story short, you could probably use the inspect module to make an educated guess about which one it is, but you would have to probably know what frame you're working in/traverse down the stack to find the right one. But I'd hate to imagine how much fun this would be trying to deal with eval/exec'ed code.

sys.dm_tran_locks contains the locking information of the sessions

If you want to know a specific table is locked or not, you can use the following query

SELECT 
 * 
from 
 sys.dm_tran_locks 
where 
  resource_associated_entity_id = object_id('schemaname.tablename')

if you are interested in finding both login name of the user and the query being run

SELECT
 DB_NAME(resource_database_id)
 , s.original_login_name
 , s.status
 , s.program_name
 , s.host_name

An updated answer reflecting changed times:

GitPython currently is the easiest to use. It supports wrapping of many git plumbing commands and has pluggable object database (dulwich being one of them), and if a command isn't implemented, provides an easy api for shelling out to the command line. For example:

repo = Repo('.')
repo.checkout(b='new_branch')

This calls:

bash$ git checkout -b new_branch

Dulwich is also good but much lower level. It's somewhat of a pain to use because it requires operating on git objects at the plumbing level and doesn't have nice porcelain that you'd normally want to do. However, if you plan on modifying any parts of git, or use git-receive-pack and git-upload-pack, you need to use dulwich.

I checked the recursive includes, I spotted the header files which include (recursively) some #include "windows.h" and #include "Winsock.h" and write a #include "Winsock2.h". in this files, i added #include "Winsock2.h" as the first include.

Just a matter of patience, look at includes one by one and establish this order, first #include "Winsock2.h" then #include "windows.h"

Yes. This error is a structured exception that wasn't mapped into a .NET error. It's probably your DataGrid mapping throwing a native exception that was uncaught.

You can tell what exception is occurring by looking at the ExternalException.ErrorCode property. I'd check your stack trace, and if it's tied to the DevExpress grid, report the problem to them.

You can't add a list to a set because lists are mutable, meaning that you can change the contents of the list after adding it to the set.

You can however add tuples to the set, because you cannot change the contents of a tuple:

>>> a.add(('f', 'g'))
>>> print a
set(['a', 'c', 'b', 'e', 'd', ('f', 'g')])

Edit: some explanation: The documentation defines a set as an unordered collection of distinct hashable objects. The objects have to be hashable so that finding, adding and removing elements can be done faster than looking at each individual element every time you perform these operations. The specific algorithms used are explained in the Wikipedia article. Pythons hashing algorithms are explained on effbot.org and pythons __hash__ function in the python reference.

Some facts:

• Set elements as well as dictionary keys have to be hashable
• Some unhashable datatypes:
  • list: use tuple instead
  • set: use frozenset instead
  • dict: has no official counterpart, but there are some recipes
• Object instances are hashable by default with each instance having a unique hash. You can override this behavior as explained in the python reference.

You can map next and previous to function keys too, making cycling through buffers a breeze

map <F2> :bprevious<CR>
map <F3> :bnext<CR>

Check validity of the MX record of the host of the given email. This can eliminate errors to the right of the @ sign.

You could do this with an AJAX call before submit and/or server side after the form is submitted.

Perhaps not what you were asking, but ... If you use a numpy array, it will do the work for you, efficiently:

from numpy import array

nums = array(((0.01, 0.01, 0.02, 0.04, 0.03),
              (0.00, 0.02, 0.02, 0.03, 0.02),
              (0.01, 0.02, 0.02, 0.03, 0.02),
              (0.01, 0.00, 0.01, 0.05, 0.03)))

print nums.std(axis=1)
# [ 0.0116619   0.00979796  0.00632456  0.01788854]

print nums.mean(axis=1)
# [ 0.022  0.018  0.02   0.02 ]

By the way, there's some interesting discussion in this blog post and comments on one-pass methods for computing means and variances:

• http://lingpipe-blog.com/2009/03/19/computing-sample-mean-variance-online-one-pass/

I added the option to choose the length using the Ranvir solution

public static string GenerateRandomString(int length)
    {
        {
            string randomString= string.Empty;

            while (randomString.Length <= length)
            {
                randomString+= Path.GetRandomFileName();
                randomString= randomString.Replace(".", string.Empty);
            }

            return randomString.Substring(0, length);
        }
    }

It's a matter of preference, but I prefer to see scripts that consistently use the slash - this way all "units" of work (creating a PL/SQL object, running a PL/SQL anonymous block, and executing a DML statement) can be picked out more easily by eye.

Also, if you eventually move to something like Ant for deployment it will simplify the definition of targets to have a consistent statement delimiter.

Subdirectories are not allowed, the resource must contain only [a-z0-9_.].

No you have uppercase letters, and no forward slashes.

FYI, this is probably faster,

SELECT count(1) FROM (SELECT distinct productId WHERE keyword = '$keyword') temp

than this,

SELECT COUNT(DISTINCT productId) WHERE keyword='$keyword'

Don't forget about fragmentation. If you have a lot of traffic, your pools can be fragmented and even if you have several MB free, there could be no block larger than 4KB. Check size of largest free block with a query like:

Since many people are probably viewing this answer when searching for log4j2 and nearly all current answers do not consider log4j2 or recent changes in it, this should hopefully answer the question.

log4j2 supports Suppliers (currently their own implementation, but according to the documentation it is planned to use Java's Supplier interface in version 3.0). You can read a little bit more about this in the manual. This allows you to put expensive log message creation into a supplier which only creates the message if it is going to be logged:

LogManager.getLogger().debug(() -> createExpensiveLogMessage());

The solution is very simple. git checkout <filename> tries to check out file from the index, and therefore fails on merge.

What you need to do is (i.e. checkout a commit):

To checkout your own version you can use one of:

git checkout HEAD -- <filename>

or

git checkout --ours -- <filename>

(Warning!: If you are rebasing --ours and --theirs are swapped.)

or

git show :2:<filename> > <filename> # (stage 2 is ours)

To checkout the other version you can use one of:

git checkout test-branch -- <filename>

or

git checkout --theirs -- <filename>

or

git show :3:<filename> > <filename> # (stage 3 is theirs)

You would also need to run 'add' to mark it as resolved:

git add <filename>

Standard approach:

from collections import defaultdict

words = "apple banana apple strawberry banana lemon"
words = words.split()
result = defaultdict(int)
for word in words:
    result[word] += 1

print result

Groupby oneliner:

from itertools import groupby

words = "apple banana apple strawberry banana lemon"
words = words.split()

result = dict((key, len(list(group))) for key, group in groupby(sorted(words)))
print result

Guys use this code for adding nodes and childnodes for TreeView from C# code. *

KISS (Keep It Simple & Stupid :)*

protected void Button1_Click(object sender, EventArgs e)

{

        TreeNode a1 = new TreeNode("Apple");

        TreeNode b1 = new TreeNode("Banana");
        TreeNode a2 = new TreeNode("gree apple");
        TreeView2.Nodes.Add(a1);
        TreeView2.Nodes.Add(b1);
        a1.ChildNodes.Add(a2);

}

Here is complete example using NLog

using NLog;
using System;
using System.Windows;

namespace MyApp
{
    /// <summary>
    /// Interaction logic for App.xaml
    /// </summary>
    public partial class App : Application

        private static Logger logger = LogManager.GetCurrentClassLogger();

        public App()
        {
            var currentDomain = AppDomain.CurrentDomain;
            currentDomain.UnhandledException += CurrentDomain_UnhandledException;
        }

        private void CurrentDomain_UnhandledException(object sender, UnhandledExceptionEventArgs e)
        {
            var ex = (Exception)e.ExceptionObject;
            logger.Error("UnhandledException caught : " + ex.Message);
            logger.Error("UnhandledException StackTrace : " + ex.StackTrace);
            logger.Fatal("Runtime terminating: {0}", e.IsTerminating);

Below is a slightly improved version of Dídac Pérez's answer, with both directions implemented, along with a demo of these functions' usages using unsigned char and unsigned long long values. Several notes:

1. The functions are inlined for compiler optimizations
2. I used a cout << +value trick for tersely outputting an unsigned char numerically that I found here: https://stackoverflow.com/a/28414758/1599699
3. I recommend using the explicit <put the type here> syntax for clarity and safety.
4. I used unsigned char for the shiftNum parameter because of what I found in the Additional Details section here:

The result of a shift operation is undefined if additive-expression is negative or if additive-expression is greater than or equal to the number of bits in the (promoted) shift-expression.

Here's the code I'm using:

#include <iostream>

using namespace std;

template <typename T>
inline T rotateAndCarryLeft(T rotateMe, unsigned char shiftNum)
{
    static const unsigned char TBitCount = sizeof(T) * 8U;

    return (rotateMe << shiftNum) | (rotateMe >> (TBitCount - shiftNum));
}

template <typename T>
inline T rotateAndCarryRight(T rotateMe, unsigned char shiftNum)
{
    static const unsigned char TBitCount = sizeof(T) * 8U;

    return (rotateMe >> shiftNum) | (rotateMe << (TBitCount - shiftNum));
}

void main()
{
    //00010100 == (unsigned char)20U
    //00000101 == (unsigned char)5U == rotateAndCarryLeft(20U, 6U)
    //01010000 == (unsigned char)80U == rotateAndCarryRight(20U, 6U)

    cout << "unsigned char " << 20U << " rotated left by 6 bits == " << +rotateAndCarryLeft<unsigned char>(20U, 6U) << "\n";
    cout << "unsigned char " << 20U << " rotated right by 6 bits == " << +rotateAndCarryRight<unsigned char>(20U, 6U) << "\n";

    cout << "\n";


    for (unsigned char shiftNum = 0U; shiftNum <= sizeof(unsigned char) * 8U; ++shiftNum)
    {
        cout << "unsigned char " << 21U << " rotated left by " << +shiftNum << " bit(s) == " << +rotateAndCarryLeft<unsigned char>(21U, shiftNum) << "\n";
    }

    cout << "\n";

    for (unsigned char shiftNum = 0U; shiftNum <= sizeof(unsigned char) * 8U; ++shiftNum)
    {
        cout << "unsigned char " << 21U << " rotated right by " << +shiftNum << " bit(s) == " << +rotateAndCarryRight<unsigned char>(21U, shiftNum) << "\n";
    }


    cout << "\n";

    for (unsigned char shiftNum = 0U; shiftNum <= sizeof(unsigned long long) * 8U; ++shiftNum)
    {
        cout << "unsigned long long " << 3457347ULL << " rotated left by " << +shiftNum << " bit(s) == " << rotateAndCarryLeft<unsigned long long>(3457347ULL, shiftNum) << "\n";
    }

    cout << "\n";

    for (unsigned char shiftNum = 0U; shiftNum <= sizeof(unsigned long long) * 8U; ++shiftNum)
    {
        cout << "unsigned long long " << 3457347ULL << " rotated right by " << +shiftNum << " bit(s) == " << rotateAndCarryRight<unsigned long long>(3457347ULL, shiftNum) << "\n";
    }

    cout << "\n\n";
    system("pause");
}

The information I give here is not new, I just added this for completeness.

The idea of this code is quite simple:

• Objects need a unique ID, which isn't there by default. Instead, we have to rely on the next best thing, which is RuntimeHelpers.GetHashCode to get us a sort-of unique ID
• To check uniqueness, this implies we need to use object.ReferenceEquals
• However, we would still like to have a unique ID, so I added a GUID, which is by definition unique.
• Because I don't like locking everything if I don't have to, I don't use ConditionalWeakTable.

Combined, that will give you the following code:

public class UniqueIdMapper
{
    private class ObjectEqualityComparer : IEqualityComparer<object>
    {
        public bool Equals(object x, object y)
        {
            return object.ReferenceEquals(x, y);
        }

        public int GetHashCode(object obj)
        {
            return RuntimeHelpers.GetHashCode(obj);
        }
    }

    private Dictionary<object, Guid> dict = new Dictionary<object, Guid>(new ObjectEqualityComparer());
    public Guid GetUniqueId(object o)
    {
        Guid id;
        if (!dict.TryGetValue(o, out id))
        {
            id = Guid.NewGuid();
            dict.Add(o, id);
        }
        return id;
    }
}

To use it, create an instance of the UniqueIdMapper and use the GUID's it returns for the objects.

Addendum

So, there's a bit more going on here; let me write a bit down about ConditionalWeakTable.

ConditionalWeakTable does a couple of things. The most important thing is that it doens't care about the garbage collector, that is: the objects that you reference in this table will be collected regardless. If you lookup an object, it basically works the same as the dictionary above.

Curious no? After all, when an object is being collected by the GC, it checks if there are references to the object, and if there are, it collects them. So if there's an object from the ConditionalWeakTable, why will the referenced object be collected then?

ConditionalWeakTable uses a small trick, which some other .NET structures also use: instead of storing a reference to the object, it actually stores an IntPtr. Because that's not a real reference, the object can be collected.

So, at this point there are 2 problems to address. First, objects can be moved on the heap, so what will we use as IntPtr? And second, how do we know that objects have an active reference?

• The object can be pinned on the heap, and its real pointer can be stored. When the GC hits the object for removal, it unpins it and collects it. However, that would mean we get a pinned resource, which isn't a good idea if you have a lot of objects (due to memory fragmentation issues). This is probably not how it works.
• When the GC moves an object, it calls back, which can then update the references. This might be how it's implemented judging by the external calls in DependentHandle - but I believe it's slightly more sophisticated.
• Not the pointer to the object itself, but a pointer in the list of all objects from the GC is stored. The IntPtr is either an index or a pointer in this list. The list only changes when an object changes generations, at which point a simple callback can update the pointers. If you remember how Mark & Sweep works, this makes more sense. There's no pinning, and removal is as it was before. I believe this is how it works in DependentHandle.

This last solution does require that the runtime doesn't re-use the list buckets until they are explicitly freed, and it also requires that all objects are retrieved by a call to the runtime.

If we assume they use this solution, we can also address the second problem. The Mark & Sweep algorithm keeps track of which objects have been collected; as soon as it has been collected, we know at this point. Once the object checks if the object is there, it calls 'Free', which removes the pointer and the list entry. The object is really gone.

One important thing to note at this point is that things go horribly wrong if ConditionalWeakTable is updated in multiple threads and if it isn't thread safe. The result would be a memory leak. This is why all calls in ConditionalWeakTable do a simple 'lock' which ensures this doesn't happen.

Another thing to note is that cleaning up entries has to happen once in a while. While the actual objects will be cleaned up by the GC, the entries are not. This is why ConditionalWeakTable only grows in size. Once it hits a certain limit (determined by collision chance in the hash), it triggers a Resize, which checks if objects have to be cleaned up -- if they do, free is called in the GC process, removing the IntPtr handle.

I believe this is also why DependentHandle is not exposed directly - you don't want to mess with things and get a memory leak as a result. The next best thing for that is a WeakReference (which also stores an IntPtr instead of an object) - but unfortunately doesn't include the 'dependency' aspect.

What remains is for you to toy around with the mechanics, so that you can see the dependency in action. Be sure to start it multiple times and watch the results:

class DependentObject
{
    public class MyKey : IDisposable
    {
        public MyKey(bool iskey)
        {
            this.iskey = iskey;
        }

        private bool disposed = false;
        private bool iskey;

        public void Dispose()
        {
            if (!disposed)
            {
                disposed = true;
                Console.WriteLine("Cleanup {0}", iskey);
            }
        }

        ~MyKey()
        {
            Dispose();
        }
    }

    static void Main(string[] args)
    {
        var dep = new MyKey(true); // also try passing this to cwt.Add

        ConditionalWeakTable<MyKey, MyKey> cwt = new ConditionalWeakTable<MyKey, MyKey>();
        cwt.Add(new MyKey(true), dep); // try doing this 5 times f.ex.

        GC.Collect(GC.MaxGeneration);
        GC.WaitForFullGCComplete();

        Console.WriteLine("Wait");
        Console.ReadLine(); // Put a breakpoint here and inspect cwt to see that the IntPtr is still there
    }

for simple,

Stored Procedure are Stored Programs, A program/function stored into database.

Each stored program contains a body that consists of an SQL statement. This statement may be a compound statement made up of several statements separated by semicolon (;) characters.

CREATE PROCEDURE dorepeat(p1 INT)
BEGIN
  SET @x = 0;
  REPEAT SET @x = @x + 1; UNTIL @x > p1 END REPEAT;
END;

In my case I had special instruction into nginx configuration file:

location ~ \.(js|css|png|jpg|gif|swf|ico|pdf|mov|fla|zip|rar)$ {
            try_files $uri =404;
    }

All clients have received '404' because nginx nothing known about Flask.

I hope it help someone.

Since the OP asked for the list of the tensors instead of the list of operations/nodes, the code should be slightly different:

graph = tf.get_default_graph()    
tensors_per_node = [node.values() for node in graph.get_operations()]
tensor_names = [tensor.name for tensors in tensors_per_node for tensor in tensors]

If you don't have the API enabled, but have an API key, you won't get that error if you run an API from the browser (such as when displaying a map) or pass the request to the curl command. You only get that error if you call an API within code. In Python, it doesn't matter if you use urllib, pycurl, construct the curl command and pass it to subprocess.check_output(), or send the request using jQuery.get(); you still get that error. I wonder how Google knows the difference.

You're not reading the file content:

my_file_contents = f.read()

See the docs for further infos

You could, without calling read() or readlines() loop over your file object:

f = open('goodlines.txt')
for line in f:
    print(line)

If you want a list out of it (without \n as you asked)

my_list = [line.rstrip('\n') for line in f]

img {
    float:left;
}
h3 {
    float:right;
}

jsFiddle example

Note that you will probably want to use the style clear:both on whatever elements comes after the code you provided so that it doesn't slide up directly beneath the floated elements.

You could try something like this:

select *
from jobdetails
where job_no like '071[12]%'

Not exactly what you're asking, but it has the same effect, and is flexible in other ways too :)

Just check for some preference with default value indicating that it's a first run. So if you get default value, do your initialization and set this preference to different value to indicate that the app is initialized already.

Overriding -textRectForBounds: will only change the inset of the placeholder text. To change the inset of the editable text, you need to also override -editingRectForBounds:

// placeholder position
- (CGRect)textRectForBounds:(CGRect)bounds {
     return CGRectInset(bounds, 10, 10);
}

// text position
- (CGRect)editingRectForBounds:(CGRect)bounds {
     return CGRectInset(bounds, 10, 10);
}

You can not serialize a Python 3 'string' to bytes without explict conversion to some encoding.

outfile.write(plaintext.encode('utf-8'))

is possibly what you want. Also this works for both python 2.x and 3.x.

You need to uninstall IIS (Internet Information Services) but the key thing here is to make sure you uninstall the Windows Process Activation Service or otherwise your ApplicationHost.config will be still around. When you uninstall WAS then your configuration will be cleaned up and you will truly start with a fresh new IIS (and all data/configuration will be lost).

Remove the course_enrollment_settings.base_price immediately after CASE:

SELECT
   CASE
    WHEN course_enrollment_settings.base_price = 0      THEN 1
    ...
    END

CASE has two different forms, as detailed in the manual. Here, you want the second form since you're using search conditions.

I usually do like this to remove most of the noise:

void LogException(Exception error) {
    Exception realerror = error;
    while (realerror.InnerException != null)
        realerror = realerror.InnerException;

    Console.WriteLine(realerror.ToString())
}    

Edit: I forgot about this answer and is surprised no one pointed out that you can just do

void LogException(Exception error) {
    Console.WriteLine(error.GetBaseException().ToString())
}    

If you want to use input instead of raw_input in python 2.x,then this trick will come handy

    if hasattr(__builtins__, 'raw_input'):
      input=raw_input

After which,

testVar = input("Ask user for something.")

will work just fine.

You can put your file to /etc/cron.d/ in cron format. Add some unique prefix to the filenaname To list script-specific cron jobs simply work with a list of files with a unique prefix. Delete the file when you want to disable the job.

I would set the maximum size, minimum size and remove the gripper icon of the window.

Set properties (MaximumSize, MinimumSize, and SizeGripStyle):

this.MaximumSize = new System.Drawing.Size(500, 550);
this.MinimumSize = new System.Drawing.Size(500, 550);
this.SizeGripStyle = System.Windows.Forms.SizeGripStyle.Hide;

Convert the image to a byte[] and store that in the database.

Add this column to your model:

public byte[] Content { get; set; }

Then convert your image to a byte array and store that like you would any other data:

public byte[] ImageToByteArray(System.Drawing.Image imageIn)
{
    using(var ms = new MemoryStream())
    {
        imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);

        return ms.ToArray();
    }
}

public Image ByteArrayToImage(byte[] byteArrayIn)
{
     using(var ms = new MemoryStream(byteArrayIn))
     {
         var returnImage = Image.FromStream(ms);

         return returnImage;
     }
}

Source: Fastest way to convert Image to Byte array

var image = new ImageEntity()
{
   Content = ImageToByteArray(image)
};

_context.Images.Add(image);
_context.SaveChanges();

When you want to get the image back, get the byte array from the database and use the ByteArrayToImage and do what you wish with the Image

This stops working when the byte[] gets to big. It will work for files under 100Mb

display:block

takes the entire row(100%)of the screen ,it is always 100%of the screen size

display block example

display:inline-block takes up as much width as necessary ,it can be 1%-to 100% of the screen size

display inline-block example

that's why we have div and span

Div default styling is display block :it takes the entire width of the screen

span default styling is display:inline block :span does not start on a new line and only takes up as much width as necessary

I don't know exactly how C calculates PI directly as I'm more familiar with C++ than C; however, you could either have a predefined C macro or const such as:

#define PI 3.14159265359.....
const float PI = 3.14159265359.....
const double PI = 3.14159265359.....
/* If your machine,os & compiler supports the long double */
const long double PI = 3.14159265359..... 

or you could calculate it with either of these two formulas:

#define M_PI acos(-1.0);
#define M_PI (4.0 * atan(1.0)); // tan(pi/4) = 1 or acos(-1)

IMHO I'm not 100% certain but I think atan() is cheaper than acos().

Fundamentally you hadn't declare location which is what nginx uses to bind URL with resources.

 server {
            listen       80;
            server_name  localhost;

            access_log  logs/localhost.access.log  main;

            location / {
                root /var/www/board/public;
                index index.html index.htm index.php;
            }
       }

I was struggling with similar problem (with mail) in one of my git's post_receive hooks and finally I found out, that sendmail actually works better for that kind of things, especially if you know a bit of how e-mails are constructed (and it seems like you know). I know this answer comes very late, but maybe it will be of some use to others too. I made use of heredoc operator and use of the feature, that it expands variables, so it can also run inlined scripts. Just check this out (bash script):

#!/bin/bash
recipients=(
    '[email protected]'
    '[email protected]'
#   '[email protected]'
);
sender='[email protected]';
subject='Oh, who really cares, seriously...';
sendmail -t <<-MAIL
    From: ${sender}
    `for r in "${recipients[@]}"; do echo "To: ${r}"; done;`
    Subject: ${subject}
    Content-Type: text/html; charset=UTF-8

    <html><head><meta charset="UTF-8"/></head>
    <body><p>Ladies and gents, here comes the report!</p>
    <pre>`mysql -u ***** -p***** -H -e "SELECT * FROM users LIMIT 20"`</pre>
    </body></html>
MAIL

Note of backticks in the MAIL part to generate some output and remember, that <<- operator strips only tabs (not spaces) from the beginning of lines, so in that case copy-paste will not work (you need to replace indentation with proper tabs). Or use << operator and make no indentation at all. Hope this will help someone. Of course you can use backticks outside o MAIL part and save the output into some variable, that you can later use in the MAIL part — matter of taste and readability. And I know, #!/bin/bash does not always work on every system.

Fix: Unlock your device before running it.

Hi Guys: Think I may have a fix for this:

Sounds ridiculous but try unlocking your Virtual Device; i.e. use your mouse to swipe and open. Your app should then work!!

If you use cell.imageView?.translatesAutoresizingMaskIntoConstraints = false you can set constraints on the imageView. Here's a working example I used in a project. I avoided subclassing and didn't need to create storyboard with prototype cells but did take me quite a while to get running, so probably best to only use if there isn't a simpler or more concise way available to you.

override func tableView(_ tableView: UITableView, heightForRowAt indexPath: IndexPath) -> CGFloat {
    return 80
}



    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    let cell = UITableViewCell(style: .subtitle, reuseIdentifier: String(describing: ChangesRequiringApprovalTableViewController.self))

    let record = records[indexPath.row]

    cell.textLabel?.text = "Title text"

    if let thumb = record["thumbnail"] as? CKAsset, let image = UIImage(contentsOfFile: thumb.fileURL.path) {
        cell.imageView?.contentMode = .scaleAspectFill
        cell.imageView?.image = image
        cell.imageView?.translatesAutoresizingMaskIntoConstraints = false
        cell.imageView?.leadingAnchor.constraint(equalTo: cell.contentView.leadingAnchor).isActive = true
        cell.imageView?.widthAnchor.constraint(equalToConstant: 80).rowHeight).isActive = true
        cell.imageView?.heightAnchor.constraint(equalToConstant: 80).isActive = true
        if let textLabel = cell.textLabel {
            let margins = cell.contentView.layoutMarginsGuide
            textLabel.translatesAutoresizingMaskIntoConstraints = false
            cell.imageView?.trailingAnchor.constraint(equalTo: textLabel.leadingAnchor, constant: -8).isActive = true
            textLabel.topAnchor.constraint(equalTo: margins.topAnchor).isActive = true
            textLabel.trailingAnchor.constraint(equalTo: margins.trailingAnchor).isActive = true
            let bottomConstraint = textLabel.bottomAnchor.constraint(equalTo: margins.bottomAnchor)
            bottomConstraint.priority = UILayoutPriorityDefaultHigh
            bottomConstraint.isActive = true
            if let description = cell.detailTextLabel {
                description.translatesAutoresizingMaskIntoConstraints = false
                description.bottomAnchor.constraint(equalTo: margins.bottomAnchor).isActive = true
                description.trailingAnchor.constraint(equalTo: margins.trailingAnchor).isActive = true
                cell.imageView?.trailingAnchor.constraint(equalTo: description.leadingAnchor, constant: -8).isActive = true
                textLabel.bottomAnchor.constraint(equalTo: description.topAnchor).isActive = true
            }
        }
        cell.imageView?.clipsToBounds = true
    }

    cell.detailTextLabel?.text = "Detail Text"

    return cell
}

From the docs:

Use the LinkButton control to create a hyperlink-style button on the Web page. The LinkButton control has the same appearance as a HyperLink control, but has the same functionality as a Button control. If you want to link to another Web page when the control is clicked, consider using the HyperLink control.

As this isn't actually performing a link in the standard sense, there's no Target property on the control (the HyperLink control does have a Target) - it's attempting to perform a PostBack to the server from a text link.

Depending on what you are trying to do you could either:

1. Use a HyperLink control, and set the Target property
2. Provide a method to the OnClientClick property that opens a new window to the correct place.
3. In your code that handles the PostBack add some JavaScript to fire on PageLoad that will open a new window correct place.

I would suggest to use this extension method to chunk the source list to the sub-lists by specified chunk size:

/// <summary>
/// Helper methods for the lists.
/// </summary>
public static class ListExtensions
{
    public static List<List<T>> ChunkBy<T>(this List<T> source, int chunkSize) 
    {
        return source
            .Select((x, i) => new { Index = i, Value = x })
            .GroupBy(x => x.Index / chunkSize)
            .Select(x => x.Select(v => v.Value).ToList())
            .ToList();
    }
}

For example, if you chunk the list of 18 items by 5 items per chunk, it gives you the list of 4 sub-lists with the following items inside: 5-5-5-3.

One does not imply the other. For a language to be statically typed it means that the types of all variables are known or inferred at compile time.

A strongly typed language does not allow you to use one type as another. C is a weakly typed language and is a good example of what strongly typed languages don't allow. In C you can pass a data element of the wrong type and it will not complain. In strongly typed languages you cannot.

This works for me:

git init
git config --global http.sslVerify false
git clone https://myurl/myrepo.git

It seems you cannot have your project root, with the AndroidManifest.xml deeper than one directory level below your workspace root. I struggled for an hour with this before I just gave up and rearranged my repo.

Using arrow function :

You must install stage-2:

npm install babel-preset-stage-2 :

class App extends React.Component {
    constructor(props) {
        super(props);
        this.state = {
            value=0
        }
    }

    changeValue = (data) => (e) => {
        alert(data);  //10
        this.setState({ [value]: data })
    }

    render() {
        const data = 10;
        return (
            <div>
                <input type="button" onClick={this.changeValue(data)} />
            </div>
        );
    }
}
export default App; 

SLF4J 1.5.11 and 1.6.0 versions are not compatible (see compatibility report) because the argument list of org.slf4j.spi.LocationAwareLogger.log method has been changed (added Object[] p5):

SLF4J 1.5.11:

LocationAwareLogger.log ( org.slf4j.Marker p1, String p2, int p3,
                          String p4, Throwable p5 )

SLF4J 1.6.0:

LocationAwareLogger.log ( org.slf4j.Marker p1, String p2, int p3,
                          String p4, Object[] p5, Throwable p6 )

See compatibility reports for other SLF4J versions on this page.

You can generate such reports by the japi-compliance-checker tool.

You can also use an express framework

app.get("/:id",function(req,res)
{
  var id = req.params.id;
  res.render("home.ejs",{identity : id});
});

Express file, which receives a JS variable identity from node.js

Problem Cause

In mac os image rendering back end of matplotlib (what-is-a-backend to render using the API of Cocoa by default). There are Qt4Agg and GTKAgg and as a back-end is not the default. Set the back end of macosx that is differ compare with other windows or linux os.

Solution

• I assume you have installed the pip matplotlib, there is a directory in your root called ~/.matplotlib.
• Create a file ~/.matplotlib/matplotlibrc there and add the following code: backend: TkAgg

I think the best solution I have come across is on this stackoverflow. This short jQuery code allows all your hover effects to show on click or touch..
No need to add anything within the function.

$('body').on('touchstart', function() {});

Hope this helps.

I think best method is to query pg_setting view:

This not work on IOS, setState -> render -> not change the text, but can change other. The textinput can't change itself value when textOnChange.

by the way, This work well on Android.

I had the same question but applying the provided solutions changed the file to write in. Once I selected the new excel file, I was also writing in that file and not in my original file. My solution for this issue is below:

Sub GetData()

    Dim excelapp As Application
    Dim source As Workbook
    Dim srcSH1 As Worksheet
    Dim sh As Worksheet
    Dim path As String
    Dim nmr As Long
    Dim i As Long

    nmr = 20

    Set excelapp = New Application

    With Application.FileDialog(msoFileDialogOpen)
        .AllowMultiSelect = False
        .Filters.Add "Excel Files", "*.xlsx; *.xlsm; *.xls; *.xlsb", 1
        .Show
        path = .SelectedItems.Item(1)
    End With

    Set source = excelapp.Workbooks.Open(path)
    Set srcSH1 = source.Worksheets("Sheet1")
    Set sh = Sheets("Sheet1")

    For i = 1 To nmr
        sh.Cells(i, "A").Value = srcSH1.Cells(i, "A").Value
    Next i

End Sub

With excelapp a new application will be called. The with block sets the path for the external file. Finally, I set the external Workbook with source and srcSH1 as a Worksheet within the external sheet.

Get the position of the first space:

int space1 = theString.IndexOf(' ');

The the position of the next space after that:

int space2 = theString.IndexOf(' ', space1 + 1);

Get the part of the string up to the second space:

string firstPart = theString.Substring(0, space2);

The above code put togehter into a one-liner:

string firstPart = theString.Substring(0, theString.IndexOf(' ', theString.IndexOf(' ') + 1));

@user1417684 and @chris-foster are right!

excerpt from working code (without error handling):

var SubItemModel = mongoose.model('subitems', SubItemSchema);
var ItemModel    = mongoose.model('items', ItemSchema);

var new_sub_item_model = new SubItemModel(new_sub_item_plain);
new_sub_item_model.save(function (error, new_sub_item) {

  var new_item = new ItemModel(new_item);
  new_item.subitem = new_sub_item._id;
  new_item.save(function (error, new_item) {
    // so this is a valid way to populate via the Model
    // as documented in comments above (here @stack overflow):
    ItemModel.populate(new_item, { path: 'subitem', model: 'subitems' }, function(error, new_item) {
      callback(new_item.toObject());
    });
    // or populate directly on the result object
    new_item.populate('subitem', function(error, new_item) {
      callback(new_item.toObject());
    });
  });

});

UUHHIVS's is a very elegant and fast way for batch delete, but it must be used with care:

• auto generation of transaction: its queries will be encompassed by a transaction
• database context independence: its execution has nothing to do with context.SaveChanges()

These issues can be circumvented by taking control of the transaction. The following code illustrates how to batch delete and bulk insert in a transactional manner:

var repo = DataAccess.EntityRepository;
var existingData = repo.All.Where(x => x.ParentId == parentId);  

TransactionScope scope = null;
try
{
    // this starts the outer transaction 
    using (scope = new TransactionScope(TransactionScopeOption.Required))
    {
        // this starts and commits an inner transaction
        existingData.Delete();

        // var toInsert = ... 

        // this relies on EntityFramework.BulkInsert library
        repo.BulkInsert(toInsert);

        // any other context changes can be performed

        // this starts and commit an inner transaction
        DataAccess.SaveChanges();

        // this commit the outer transaction
        scope.Complete();
    }
}
catch (Exception exc)
{
    // this also rollbacks any pending transactions
    scope?.Dispose();
}

Adding to slebetman's answer for more clarity on what happens while executing the code.

The internal thread pool in nodeJs just has 4 threads by default. and its not like the whole request is attached to a new thread from the thread pool the whole execution of request happens just like any normal request (without any blocking task) , just that whenever a request has any long running or a heavy operation like db call ,a file operation or a http request the task is queued to the internal thread pool which is provided by libuv. And as nodeJs provides 4 threads in internal thread pool by default every 5th or next concurrent request waits until a thread is free and once these operations are over the callback is pushed to the callback queue. and is picked up by event loop and sends back the response.

Now here comes another information that its not once single callback queue, there are many queues.

1. NextTick queue
2. Micro task queue
3. Timers Queue
4. IO callback queue (Requests, File ops, db ops)
5. IO Poll queue
6. Check Phase queue or SetImmediate
7. close handlers queue

Whenever a request comes the code gets executing in this order of callbacks queued.

It is not like when there is a blocking request it is attached to a new thread. There are only 4 threads by default. So there is another queueing happening there.

Whenever in a code a blocking process like file read occurs , then calls a function which utilises thread from thread pool and then once the operation is done , the callback is passed to the respective queue and then executed in the order.

Everything gets queued based on the the type of callback and processed in the order mentioned above.

The server ran out of disk space, in my case.

Check for it with df -k .

I was alerted to the lack of disk space when I tried piping through tac twice, as described in one of the other answers: https://stackoverflow.com/a/28879552/336694. It showed me the error message write error: No space left on device.

Sometimes this occurs when you have the folder of the package you are trying to restore inside the "packages" folder (i.e. "Packages/EntityFramework.6.0.0/") but the "DLLs" are not inside it (most of the version control systems automatically ignore ".dll" files). This occurs because before NuGet tries to restore each package it checks if the folders already exist, so if it exists, NuGet assumes that the "dll" is inside it. So if this is the problem for you just delete the folder that NuGet will restore it correctly.

Just use https://graph.facebook.com/(your_username or page name) to get your page ID and after you can see all the detain and your ID

after in your IOS app use :

 NSURL *url = [NSURL URLWithString:@"fb://profile/[your ID]"];
 [[UIApplication sharedApplication] openURL:url];

I'd use the RANK() function in a subselect and then just pull the row where rank = 1.

select person, language
from
( 
    select person, language, rank() over(order by language) as rank
    from table A
    group by person, language
)
where rank = 1

Facebook uses MQTT instead of HTTP. Push is better than polling. Through HTTP we need to poll the server continuously but via MQTT server pushes the message to clients.

Comparision between MQTT and HTTP: http://www.youtube.com/watch?v=-KNPXPmx88E

This can help you

namedWindow( "Display window", CV_WINDOW_AUTOSIZE );// Create a window for display.
imshow( "Display window", image );                   // Show our image inside it.

Request takes a callback method, its async! So I am assuming, by the time the callback is executed the res.end() might get called. Try closing the request within the callback.

The svnbook has a section on how Subversion allows you to revert the changes from a particular revision without affecting the changes that occured in subsequent revisions:

http://svnbook.red-bean.com/en/1.4/svn.branchmerge.commonuses.html#svn.branchmerge.commonuses.undo

I don't use Eclipse much, but in TortoiseSVN you can do this from the from the log dialogue; simply right-click on the revision you want to revert and select "Revert changes from this revision".

In the case that the files for which you want to revert "bad changes" had "good changes" in subsequent revisions, then the process is the same. The changes from the "bad" revision will be reverted leaving the changes from "good" revisions untouched, however you might get conflicts.

After installing pywin32

Steps to correctly install your module (pywin32)

1. First search where is your python pip is present

   1a. For Example in my case location of pip - C:\Users\username\AppData\Local\Programs\Python\Python36-32\Scripts

2. Then open your command prompt and change directory to your pip folder location.

   cd C:\Users\username\AppData\Local\Programs\Python\Python36-32\Scripts
   
   C:\Users\username\AppData\Local\Programs\Python\Python36-32\Scripts>pip install 
   pypiwin32
   

Restart your IDE

All done now you can use the module .

Just cast one of the two operands to a float first.

v = (float)s / t;

The cast has higher precedence than the division, so happens before the division.

The other operand will be effectively automatically cast to a float by the compiler because the rules say that if either operand is of floating point type then the operation will be a floating point operation, even if the other operand is integral. Java Language Specification, §4.2.4 and §15.17

I've found the following "pattern" to be very useful:

MainCtrl.$inject = ['$scope', '$rootScope', '$location', 'socket', ...];
function MainCtrl (scope, rootscope, location, thesocket, ...) {

where, MainCtrl is a controller. I am uncomfortable relying on the parameter names of the Controller function doing a one-for-one mimic of the instances for fear that I might change names and muck things up. I much prefer explicitly using $inject for this purpose.

python -c "exec(open('main.py').read())"

Here is a suggestion I have written that takes care of multiple input in your form.

This function gets the Object of the input field, put in your code

function fieldKeyup(obj){
    //  what you want this to do

} // fieldKeyup

This is the actual delayCall function, takes care of multiple input fields

function delayCall(obj,ms,fn){
    return $(obj).each(function(){
    if ( typeof this.timer == 'undefined' ) {
       // Define an array to keep track of all fields needed delays
       // This is in order to make this a multiple delay handling     
          function
        this.timer = new Array();
    }
    var obj = this;
    if (this.timer[obj.id]){
        clearTimeout(this.timer[obj.id]);
        delete(this.timer[obj.id]);
    }

    this.timer[obj.id] = setTimeout(function(){
        fn(obj);}, ms);
    });
}; // delayCall

Usage:

$("#username").on("keyup",function(){
    delayCall($(this),500,fieldKeyup);
});

I had to stop the apache server first.

(f.e. sudo systemctl stop httpd.service / sudo systemctl disable httpd.service).

That solved my problem besides editing the 'settings.py' file

to ALLOWED_HOSTS = ['se.rv.er.ip', 'www.example.com']

Bash

To get list of keys in Bash, follow the these steps.

First, define the following wrapper function to make it simple to use (copy and paste into shell):

function memcmd() {
  exec {memcache}<>/dev/tcp/localhost/11211
  printf "%s\n%s\n" "$*" quit >&${memcache}
  cat <&${memcache}
}

Memcached 1.4.31 and above

You can use lru_crawler metadump all command to dump (most of) the metadata for (all of) the items in the cache.

As opposed to cachedump, it does not cause severe performance problems and has no limits on the amount of keys that can be dumped.

Example command by using the previously defined function:

memcmd lru_crawler metadump all

See: ReleaseNotes1431.

Memcached 1.4.30 and below

Get list of slabs by using items statistics command, e.g.:

memcmd stats items

For each slub class, you can get list of items by specifying slub id along with limit number (0 - unlimited):

memcmd stats cachedump 1 0
memcmd stats cachedump 2 0
memcmd stats cachedump 3 0
memcmd stats cachedump 4 0
...

^{Note: You need to do this for each memcached server.}

To list all the keys from all stubs, here is the one-liner (per one server):

for id in $(memcmd stats items | grep -o ":[0-9]\+:" | tr -d : | sort -nu); do
    memcmd stats cachedump $id 0
done

^{Note: The above command could cause severe performance problems while accessing the items, so it's not advised to run on live.}

Notes:

stats cachedump only dumps the HOT_LRU (IIRC?), which is managed by a background thread as activity happens. This means under a new enough version which the 2Q algo enabled, you'll get snapshot views of what's in just one of the LRU's.

If you want to view everything, lru_crawler metadump 1 (or lru_crawler metadump all) is the new mostly-officially-supported method that will asynchronously dump as many keys as you want. you'll get them out of order but it hits all LRU's, and unless you're deleting/replacing items multiple runs should yield the same results.

C array:

NSInteger array[6] = {1, 2, 3, 4, 5, 6};

Objective-C Array:

NSArray *array = @[@1, @2, @3, @4, @5, @6];
// numeric values must in that case be wrapped into NSNumbers

Swift Array:

var array = [1, 2, 3, 4, 5, 6]

This is correct too:

var array = Array(1...10)

NB: arrays are strongly typed in Swift; in that case, the compiler infers from the content that the array is an array of integers. You could use this explicit-type syntax, too:

var array: [Int] = [1, 2, 3, 4, 5, 6]

If you wanted an array of Doubles, you would use :

var array = [1.0, 2.0, 3.0, 4.0, 5.0, 6.0] // implicit type-inference

or:

var array: [Double] = [1, 2, 3, 4, 5, 6] // explicit type

Try declaring the unit of width:

e1.style.width = "400px"; // width in PIXELS

this will set your session to keep everything till the browser is closed

session.setMaxinactiveinterval(-1);

and this should set it for 1 day

session.setMaxInactiveInterval(60*60*24);

Try this:sudo /Applications/XAMPP/xamppfiles/xampp security Then follow the instructions

Sometimes it's better to think like a parser, like T-SQL parser. While executing the statement, parser does not have any value in Pivot section and you can't have any check expression in that section. By the way, you can simply use this:

SELECT  CLASS
,   IsNull([AZ], 0)
,   IsNull([CA], 0)
,   IsNull([TX], 0)
    FROM #TEMP
    PIVOT (
        SUM(DATA)
        FOR STATE IN (
            [AZ]
        ,   [CA]
        ,   [TX]
        )
    )   AS  PVT
    ORDER   BY  CLASS

Try this instead.

From: http://wiki.apache.org/httpd/FAQ#Where_can_I_download_.28certified.29_64_bit_Apache_httpd_binaries_for_Windows.3F

Where can I download (certified) 64 bit Apache httpd binaries for Windows?

Right now, there are none. The Apache Software Foundation produces Open Source Software. The 32 bit binaries provided are a courtesy of the community members.

Though there are some unofficial e.g. http://www.apachelounge.com/download/win64/, but I have no idea if they can be trusted.

This is not Windows, you do not "run the Terminal as admin". What you do is you run commands in the terminal as admin, typically using sudo:

$ sudo some command here

For a thread you have the myThread.IsAlive property. It is false if the thread method returned or the thread was aborted.

Do check the man pages of your ping command before trying some of these examples out (always good practice anyway). For Ubuntu 16 (for example) the accepted answer doesn't work as the -n 3 fails (this isn't the count of packets anymore, -n denotes not converting the IP address to a hostname).

Following the request of the OP, a potential alternative function would be as follows:

function checkPing($ip){
    $ping = trim(`which ping`);
    $ll = exec($ping . '-n -c2 ' . $ip, $output, $retVar);
    if($retVar == 0){
        echo "The IP address, $ip, is alive";
        return true;
    } else {
        echo "The IP address, $ip, is dead";
        return false;
    }
}

First select the text
To convert lowercase to uppercase, press Ctrl+Shift+U
To convert uppercase to lowercase, press Ctrl+U

I tried the other solutions here, they work but I'm lazy so this is my solution

1. hover over the element to trigger expanded state
2. ctrl+shift+c
3. hover over element again
4. right click
5. navigate to the debugger

by right clicking it no longer registers mouse event since a context menu pops up, so you can move the mouse away safely

The easiest way I found, summarized in a few pictures:

You could skip a few steps (up to step 4) by simply navigating to chrome://settings/languages right away.

You can .split() to get an array of strings, then loop through to convert them to numbers, like this:

var myArray = "14 2".split(" ");
for(var i=0; i<myArray.length; i++) { myArray[i] = +myArray[i]; } 
//use myArray, it's an array of numbers

The +myArray[i] is just a quick way to do the number conversion, if you're sure they're integers you can just do:

for(var i=0; i<myArray.length; i++) { myArray[i] = parseInt(myArray[i], 10); } 

If you are using Visual Studio 2017 and come across this question, you might consider AxoCover. It's a free VS extension that integrates OpenCover, but supports VS2017 (it also appears to be under active development. +1).

I know this is old, but I ran into the same issue. I'm on a Mac/Ubuntu and switch back and forth. What I have found is that just sending a simple interrupt signal to the main R process does exactly what you're looking for. I've ran scripts that went on for as long as 24 hours and the signal interrupt works very well. You should be able to run kill in terminal:

$ kill -2 pid

You can find the pid by running

$ps aux | grep exec/R

Not sure about Windows since I'm not ever on there, but I can't imagine there's not an option to do this as well in Command Prompt/Task Manager

Hope this helps!

Here is a good example of array_keys from PHP.js library:

function array_keys (input, search_value, argStrict) {
    // Return just the keys from the input array, optionally only for the specified search_value

    var search = typeof search_value !== 'undefined',
        tmp_arr = [],
        strict = !!argStrict,
        include = true,
        key = '';

    for (key in input) {
        if (input.hasOwnProperty(key)) {
            include = true;
            if (search) {
                if (strict && input[key] !== search_value) {
                    include = false;
                }
                else if (input[key] != search_value) {
                    include = false;
                }
            }

            if (include) {
                tmp_arr[tmp_arr.length] = key;
            }
        }
    }

    return tmp_arr;
}

The same goes for array_values (from the same PHP.js library):

function array_values (input) {
    // Return just the values from the input array  

    var tmp_arr = [],
        key = '';

    for (key in input) {
        tmp_arr[tmp_arr.length] = input[key];
    }

    return tmp_arr;
}

EDIT: Removed unnecessary clauses from the code.

I searched for some good themes across internet and found nothing. So I ported selected controls of GTK Hybrid theme. It's MIT licensed and you can find it here:

https://github.com/stil/candyshop

It's not enterprise grade style and probably has some flaws, but I use it in my personal projects.

Instead of using re.search use re.findall it will return you all matches in a List. Or you could also use re.finditer (which i like most to use) it will return an Iterator Object and you can just use it to iterate over all found matches.

line = 'bla bla bla<form>Form 1</form> some text...<form>Form 2</form> more text?'
for match in re.finditer('<form>(.*?)</form>', line, re.S):
    print match.group(1)

number = 20.5

if (number == Math.floor(number)) {

alert("Integer")

} else {

alert("Decimal")

}

Pretty cool and works for things like XX.0 too! It works because Math.floor() chops off any decimal if it has one so if the floor is different from the original number we know it is a decimal! And no string conversions :)

[[ -d "$DIR" && ! -L "$DIR" ]] && echo "It's a directory and not a symbolic link"

N.B: Quoting variables is a good practice.

Explanation:

• -d: check if it's a directory
• -L: check if it's a symbolic link

I wanted the Number same as I get from database for example.

1) 00100.220000

2) 00123

3) 0000.0000100

So I modified the code as below

$objPHPExcel->getActiveSheet()
    ->setCellValue('A3', '00100.220000');
$objPHPExcel->getActiveSheet()
    ->getStyle('A3')
    ->getNumberFormat()
    ->setFormatCode('00000.000000');


$objPHPExcel->getActiveSheet()
    ->setCellValue('A4', '00123');
$objPHPExcel->getActiveSheet()
  ->getStyle('A4')
 ->getNumberFormat()
->setFormatCode('00000');


$objPHPExcel->getActiveSheet()
    ->setCellValue('A5', '0000.0000100');
$objPHPExcel->getActiveSheet()
  ->getStyle('A5')
 ->getNumberFormat()
->setFormatCode('0000.0000000');

You should try to maintain a proper aspect ratio between the sizes you're scaling from and to. For example, if your target size is 28px, then your source size should be a power of that, such as 56 (28 x 2) or 112 (28 x 4). This ensures you can scale by 50% or 25% rather than the 0.233333% you're currently using.

Thread.interrupt() sets the interrupted status/flag of the target thread to true which when checked using Thread.interrupted() can help in stopping the endless thread. Refer http://www.yegor256.com/2015/10/20/interrupted-exception.html

I found that using the recommended table-responsive class in a wrapper still causes responsive tables to (surprisingly) shrink horizontally:

<div class="table-responsive-lg">
    <table class="table">
        ...
    </table>
</div>

The solution for me was to create the following media breakpoints and classes to prevent it:

.table-xs {
    width:544px;
}

.table-sm {
    width: 576px;
}

.table-md {
    width: 768px;
}

.table-lg {
    width: 992px;
}

.table-xl {
    width: 1200px;
}

/* Small devices (landscape phones, 544px and up) */
@media (min-width: 576px) {  
    .table-sm {
        width: 100%;
    }
}

/* Medium devices (tablets, 768px and up) The navbar toggle appears at this breakpoint */
@media (min-width: 768px) {
    .table-sm {
        width: 100%;
    }

    .table-md {
        width: 100%;
    }
}

/* Large devices (desktops, 992px and up) */
@media (min-width: 992px) {
    .table-sm {
        width: 100%;
    }

    .table-md {
        width: 100%;
    }

    .table-lg {
        width: 100%;
    }
}

/* Extra large devices (large desktops, 1200px and up) */
@media (min-width: 1200px) {
    .table-sm {
        width: 100%;
    }

    .table-md {
        width: 100%;
    }

    .table-lg {
        width: 100%;
    }

    .table-xl {
        width: 100%;
    }
}

Then I can add the appropriate class to my table element. For example:

<div class="table-responsive-lg">
    <table class="table table-lg">
        ...
    </table>
</div>

Here the wrapper sets the width to 100% for large and greater per Bootstrap. With the table-lg class applied to the table element, the table width is set also set to 100% for large and greater, but set to 992px for medium and smaller. The classes table-xs, table-sm, table-md, and table-xl work the same way.

Here is a solution where you set the ylabel of one of the plots and adjust the position of it so it is centered vertically. This way you avoid problems mentioned by KYC.

import numpy as np
import matplotlib.pyplot as plt

def set_shared_ylabel(a, ylabel, labelpad = 0.01):
    """Set a y label shared by multiple axes
    Parameters
    ----------
    a: list of axes
    ylabel: string
    labelpad: float
        Sets the padding between ticklabels and axis label"""

    f = a[0].get_figure()
    f.canvas.draw() #sets f.canvas.renderer needed below

    # get the center position for all plots
    top = a[0].get_position().y1
    bottom = a[-1].get_position().y0

    # get the coordinates of the left side of the tick labels 
    x0 = 1
    for at in a:
        at.set_ylabel('') # just to make sure we don't and up with multiple labels
        bboxes, _ = at.yaxis.get_ticklabel_extents(f.canvas.renderer)
        bboxes = bboxes.inverse_transformed(f.transFigure)
        xt = bboxes.x0
        if xt < x0:
            x0 = xt
    tick_label_left = x0

    # set position of label
    a[-1].set_ylabel(ylabel)
    a[-1].yaxis.set_label_coords(tick_label_left - labelpad,(bottom + top)/2, transform=f.transFigure)

length = 100
x = np.linspace(0,100, length)
y1 = np.random.random(length) * 1000
y2 = np.random.random(length)

f,a = plt.subplots(2, sharex=True, gridspec_kw={'hspace':0})
a[0].plot(x, y1)
a[1].plot(x, y2)
set_shared_ylabel(a, 'shared y label (a. u.)')

Are there properties that aren't 'transitional'?

Answer: Yes.

If the property is not listed here it is not 'transitional'.

Reference: Animatable CSS Properties

If you know the key which you unset then put directly by comma separated

unset($attr['placeholder'], $attr['autocomplete']);

If you are using asset catalog, and have multiple targets both using same asset catalog file, be sure that this file has checked both targets in the right panel in xcode.

That was my problem.

Complete example for using template functions in RazorEngine (for email generation, for example):

@model SomeModel
@{
    Func<PropertyChangeInfo, object> PropInfo =
        @<tr class="property">
            <td>
                @item.PropertyName                
            </td>
            <td class="value">
                <small class="old">@item.OldValue</small>
                <small class="new">@item.CurrentValue</small>                
            </td>
        </tr>;
}

@{ WriteLiteral(PropInfo(new PropertyChangeInfo("p1", @Model.Id, 2)).ToString()); }

</body>

I was cleaning up warnings and messages and see that VS does warn about it: Validation (ASP.Net): Attribute 'OnClick' is not a valid attribute of element 'CheckBox'. Use the html input control to specify a client side handler and then you won't get the extra span tag and the two elements.

So when sending the message to telegram you use:

$token = <Enter Your Token Here>
$url = "https://api.telegram.org/bot".$token;

$chat_id = <The Chat Id Goes Here>;
$test = <Message goes Here>;

//sending Message normally without styling
$response = file_get_content($url."\sendMessage?chat_id=$chat_id&text=$text");

If our message has html tags in it we add "parse_mode" so that our url becomes:

$response = file_get_content($url."\sendMessage?chat_id=$chat_id&text=$text&parse_mode=html")

parse mode can be "HTML" or "markdown"

As per different sources, I think the minimum length in E-164 format depends on country to country. For eg:

• For Israel: The minimum phone number length (excluding the country code) is 8 digits. - Official Source (Country Code 972)

• For Sweden : The minimum number length (excluding the country code) is 7 digits. - Official Source? (country code 46)

• For Solomon Islands its 5 for fixed line phones. - Source (country code 677)

... and so on. So including country code, the minimum length is 9 digits for Sweden and 11 for Israel and 8 for Solomon Islands.

Edit (Clean Solution): Actually, Instead of validating an international phone number by having different checks like length etc, you can use the Google's libphonenumber library. It can validate a phone number in E164 format directly. It will take into account everything and you don't even need to give the country if the number is in valid E164 format. Its pretty good! Taking an example:

String phoneNumberE164Format = "+14167129018"
PhoneNumberUtil phoneUtil = PhoneNumberUtil.getInstance();
try {
    PhoneNumber phoneNumberProto = phoneUtil.parse(phoneNumberE164Format, null);
    boolean isValid = phoneUtil.isValidNumber(phoneNumberProto); // returns true if valid
    if (isValid) {
        // Actions to perform if the number is valid
    } else {
        // Do necessary actions if its not valid 
    }
} catch (NumberParseException e) {
    System.err.println("NumberParseException was thrown: " + e.toString());
}

If you know the country for which you are validating the numbers, you don;t even need the E164 format and can specify the country in .parse function instead of passing null.

A stream is a continuous flow of liquid, air, or gas.

Java stream is a flow of data from a source into a destination. The source or destination can be a disk, memory, socket, or other programs. The data can be bytes, characters, or objects. The same applies for C# or C++ streams. A good metaphor for Java streams is water flowing from a tap into a bathtub and later into a drainage.

The data represents the static part of the stream; the read and write methods the dynamic part of the stream.

InputStream represents a flow of data from the source, the OutputStream represents a flow of data into the destination. Finally, InputStream and OutputStream are abstractions over low-level access to data, such as C file pointers.

You can get the type of "T" from any collection type that implements IEnumerable<T> with the following:

public static Type GetCollectionItemType(Type collectionType)
{
    var types = collectionType.GetInterfaces()
        .Where(x => x.IsGenericType 
            && x.GetGenericTypeDefinition() == typeof(IEnumerable<>))
        .ToArray();
    // Only support collections that implement IEnumerable<T> once.
    return types.Length == 1 ? types[0].GetGenericArguments()[0] : null;
}

Note that it doesn't support collection types that implement IEnumerable<T> twice, e.g.

public class WierdCustomType : IEnumerable<int>, IEnumerable<string> { ... }

I suppose you could return an array of types if you needed to support this...

Also, you might also want to cache the result per collection type if you're doing this a lot (e.g. in a loop).

Finally I have found the solution by using the following code:

$('body').on('click', '#upload', function(e){
        e.preventDefault();
        var formData = new FormData($(this).parents('form')[0]);

        $.ajax({
            url: 'upload.php',
            type: 'POST',
            xhr: function() {
                var myXhr = $.ajaxSettings.xhr();
                return myXhr;
            },
            success: function (data) {
                alert("Data Uploaded: "+data);
            },
            data: formData,
            cache: false,
            contentType: false,
            processData: false
        });
        return false;
});

If elements are in tree order, as shown in your example, you can use something like the following Python example:

delimiter = '.'
stack = []
for item in items:
  while stack and not item.startswith(stack[-1]+delimiter):
    print "</div>"
    stack.pop()
  print "<div>"
  print item
  stack.append(item)

What this does is maintain a stack representing the current position in the tree. For each element in the table, it pops stack elements (closing the matching divs) until it finds the parent of the current item. Then it outputs the start of that node and pushes it to the stack.

If you want to output the tree using indenting rather than nested elements, you can simply skip the print statements to print the divs, and print a number of spaces equal to some multiple of the size of the stack before each item. For example, in Python:

print "  " * len(stack)

You could also easily use this method to construct a set of nested lists or dictionaries.

Edit: I see from your clarification that the names were not intended to be node paths. That suggests an alternate approach:

idx = {}
idx[0] = []
for node in results:
  child_list = []
  idx[node.Id] = child_list
  idx[node.ParentId].append((node, child_list))

This constructs a tree of arrays of tuples(!). idx[0] represents the root(s) of the tree. Each element in an array is a 2-tuple consisting of the node itself and a list of all its children. Once constructed, you can hold on to idx[0] and discard idx, unless you want to access nodes by their ID.

tl;dr (this tl;dr is from @sp00m's answer below)

$emit dispatches an event upwards ... $broadcast dispatches an event downwards

Detailed explanation

$rootScope.$emit only lets other $rootScope listeners catch it. This is good when you don't want every $scope to get it. Mostly a high level communication. Think of it as adults talking to each other in a room so the kids can't hear them.

$rootScope.$broadcast is a method that lets pretty much everything hear it. This would be the equivalent of parents yelling that dinner is ready so everyone in the house hears it.

$scope.$emit is when you want that $scope and all its parents and $rootScope to hear the event. This is a child whining to their parents at home (but not at a grocery store where other kids can hear).

$scope.$broadcast is for the $scope itself and its children. This is a child whispering to its stuffed animals so their parents can't hear.

This is specifically a special case because computers represent numbers in base 2. This is generalizable:

(number)_base % base^x

is equivilent to the last x digits of (number)_base.

For me, the reason for this error was that there was a folder with the same name as the python module I was trying to import.

|-- core  <-- empty directory on the same level as the module that throws the error
|-- core.py

And python treated that folder as a python package and tried to import from that empty package "core", not from core.py.

Seems like for some reason git left that empty folder during the branches switch

So I just removed that folder and everything worked like a charm

I also encountered this mongoose error CastError: Cast to ObjectId failed for value \"583fe2c488cf652d4c6b45d1\" at path \"_id\" for model User

So I run npm list command to verify the mongodb and mongoose version in my local. Heres the report: ......
......
+-- [email protected]
+-- [email protected]
.....

It seems there's an issue on this mongodb version so what I did is I uninstall and try to use different version such as 2.2.16

$ npm uninstall mongodb, it will delete the mongodb from your node_modules directory. After that install the lower version of mongodb.
$ npm install [email protected]
Finally, I restart the app and the CastError is gone!!

The read_sql docs say this params argument can be a list, tuple or dict (see docs).

To pass the values in the sql query, there are different syntaxes possible: ?, :1, :name, %s, %(name)s (see PEP249).
But not all of these possibilities are supported by all database drivers, which syntax is supported depends on the driver you are using (psycopg2 in your case I suppose).

In your second case, when using a dict, you are using 'named arguments', and according to the psycopg2 documentation, they support the %(name)s style (and so not the :name I suppose), see http://initd.org/psycopg/docs/usage.html#query-parameters.
So using that style should work:

df = psql.read_sql(('select "Timestamp","Value" from "MyTable" '
                     'where "Timestamp" BETWEEN %(dstart)s AND %(dfinish)s'),
                   db,params={"dstart":datetime(2014,6,24,16,0),"dfinish":datetime(2014,6,24,17,0)},
                   index_col=['Timestamp'])

What is the len of the equivalent nested list?

len([[2,3,1,0], [2,3,1,0], [3,2,1,1]])

With the more general concept of shape, numpy developers choose to implement __len__ as the first dimension. Python maps len(obj) onto obj.__len__.

X.shape returns a tuple, which does have a len - which is the number of dimensions, X.ndim. X.shape[i] selects the ith dimension (a straight forward application of tuple indexing).

Use Python 2.7's mini formatting for strings:

'{0: <8}'.format('123')

This left aligns, and pads to 8 characters with the ' ' character.

Using aggregate is the right approach, but you need to $unwind the list array before applying the $match so that you can filter individual elements and then use $group to put it back together:

db.test.aggregate([
    { $match: {_id: ObjectId("512e28984815cbfcb21646a7")}},
    { $unwind: '$list'},
    { $match: {'list.a': {$gt: 3}}},
    { $group: {_id: '$_id', list: {$push: '$list.a'}}}
])

outputs:

{
  "result": [
    {
      "_id": ObjectId("512e28984815cbfcb21646a7"),
      "list": [
        4,
        5
      ]
    }
  ],
  "ok": 1
}

MongoDB 3.2 Update

Starting with the 3.2 release, you can use the new $filter aggregation operator to do this more efficiently by only including the list elements you want during a $project:

db.test.aggregate([
    { $match: {_id: ObjectId("512e28984815cbfcb21646a7")}},
    { $project: {
        list: {$filter: {
            input: '$list',
            as: 'item',
            cond: {$gt: ['$$item.a', 3]}
        }}
    }}
])

You could do this:

for idx, item in enumerate(list):
   if 'foo' in item:
       item = replace_all(...)
       list[idx] = item

The hibernate.* properties are useless, they should be spring.jpa.* properties. Not to mention that you are trying to override those already set by using the spring.jpa.* properties. (For the explanation of each property I strongly suggest a read of the Spring Boot reference guide.

spring.jpa.database-platform = org.hibernate.dialect.MySQL5Dialect
spring.jpa.show-sql = true

# Hibernate
spring.jpa.hibernate.ddl-auto=update

Also the packages to scan are automatically detected based on the base package of your Application class. If you want to specify something else use the @EntityScan annotation. Also specifying the most toplevel package isn't really wise as it will scan the whole class path which will severely impact performance.

Copying to the clipboard is a tricky task to do in Javascript in terms of browser compatibility. The best way to do it is using a small flash. It will work on every browser. You can check it in this article.

Here's how to do it for Internet Explorer:

function copy (str)
{
    //for IE ONLY!
    window.clipboardData.setData('Text',str);
}

public DataSet GetDataSet(string ConnectionString, string SQL)
{
    SqlConnection conn = new SqlConnection(ConnectionString);
    SqlDataAdapter da = new SqlDataAdapter();
    SqlCommand cmd = conn.CreateCommand();
    cmd.CommandText = SQL;
    da.SelectCommand = cmd;
    DataSet ds = new DataSet();

    ///conn.Open();
    da.Fill(ds);
    ///conn.Close();

    return ds;
}

In Mercurial you use hg log --keyword to search for keywords in the commit messages and hg log --user to search for a particular user. See hg help log for other ways to limit the log.

This is the correct answer. It will refresh the previous page.

No, prior to Oracle version 12.2, identifiers are not allowed to exceed 30 characters in length. See the Oracle SQL Language Reference.

However, from version 12.2 they can be up to 128 bytes long. (Note: bytes, not characters).

This question has been asked many times on this site and the definitive answer is: NO, you can't connect an Android phone to an iPhone over Bluetooth, and YES Apple has restrictions that prevent this.

Some possible alternatives:

1. Bonjour over WiFi, as you mentioned. However, I couldn't find a comprehensive tutorial for it.
2. Some internet based sync service, like Dropbox, Google Drive, Amazon S3. These usually have libraries for several platforms.
3. Direct TCP/IP communication over sockets. (How to write a small (socket) server in iOS)
4. Bluetooth Low Energy will be possible once the issues on the Android side are solved (Communicating between iOS and Android with Bluetooth LE)

Coolest alternative: use the Bump API. It has iOS and Android support and really easy to integrate. For small payloads this can be the most convenient solution.

Details on why you can't connect an arbitrary device to the iPhone. iOS allows only some bluetooth profiles to be used without the Made For iPhone (MFi) certification (HPF, A2DP, MAP...). The Serial Port Profile that you would require to implement the communication is bound to MFi membership. Membership to this program provides you to the MFi authentication module that has to be added to your hardware and takes care of authenticating the device towards the iPhone. Android phones don't have this module, so even though the physical connection may be possible to build up, the authentication step will fail. iPhone to iPhone communication is possible as both ends are able to authenticate themselves.

I'm on a mac and use homebrew to install open source programs. I did have to install mac Dev tools in order to install homebrew, but after that it was a simple:

brew install mysql

to install mysql. I haven't had a mysql gem problem since.

Don't Return Empty Json

In My Case I was returning Empty Json String in .Net Core Web API Project.

So I Changed My Code

From

 return Ok();

To

 return Ok("Done");

It seems you have to return some string or object.

Hope this helps.

• An algorithm is typically deterministic and proven to yield an optimal result
• A heuristic has no proof of correctness, often involves random elements, and may not yield optimal results.

Many problems for which no efficient algorithm to find an optimal solution is known have heuristic approaches that yield near-optimal results very quickly.

There are some overlaps: "genetic algorithms" is an accepted term, but strictly speaking, those are heuristics, not algorithms.

Here is a code to get custom cell from index path

 NSIndexPath *indexPath = [NSIndexPath indexPathForRow:2 inSection:0];
 YourCell *cell = (YourCell *)[tblRegister cellForRowAtIndexPath:indexPath];

For Swift

let indexpath = NSIndexPath(forRow: 2, inSection: 0)
let currentCell = tblTest.cellForRowAtIndexPath(indexpath) as! CellTest

For Swift 4 (for collectionview)

let indexpath = NSIndexPath(row: 2, section: 0)
let cell = self.colVw!.cellForItem(at: indexpath as IndexPath) as? ColViewCell

In Firefox, you can use the instanceof Node. That Node is defined in DOM1.

But that is not that easy in IE.

1. "instanceof ActiveXObject" only can tell that it is a native object.
2. "typeof document.body.appendChild=='object'" tell that it may be DOM object, but also can be something else have same function.

You can only ensure it is DOM element by using DOM function and catch if any exception. However, it may have side effect (e.g. change object internal state/performance/memory leak)

Updating lines in place in a file is not supported on most file system (a line in a file is just some data that ends with newline, the next line start just after that).

As I see it you have two options:

1. Have your data generating loops be generators, this way they won't consume a lot of memory - you'll get data for each row "just in time"
2. Use a database (sqlite?) and update the rows there. When you're done - export to CSV

Small example for the first method:

from itertools import islice, izip, count
print list(islice(izip(count(1), count(2), count(3)), 10))

This will print

[(1, 2, 3), (2, 3, 4), (3, 4, 5), (4, 5, 6), (5, 6, 7), (6, 7, 8), (7, 8, 9), (8, 9, 10), (9, 10, 11), (10, 11, 12)]

even though count generate an infinite sequence of numbers

You don't only need the header file, you need the library that goes with it. Anyway, the include folder is not automatically loaded, you must configure your project to do so. Right-click on it : Build options > Search directories > Add. Choose your include folder, keep the path relative.

Edit For further assistance, please give details about the library you're trying to load (which provides a graphics.h file.)

List<Date> dates = new ArrayList<Date>();
String str_date = "DD/MM/YYYY";
String end_date = "DD/MM/YYYY";
DateFormat formatter = new SimpleDateFormat("dd/MM/yyyy");
Date startDate = (Date)formatter.parse(str_date); 
Date endDate = (Date)formatter.parse(end_date);
long interval = 1000 * 60 * 60; // 1 hour in milliseconds
long endTime = endDate.getTime() ; // create your endtime here, possibly using Calendar or Date
long curTime = startDate.getTime();

while (curTime <= endTime) {
    dates.add(new Date(curTime));
    curTime += interval;
}
for (int i = 0; i < dates.size(); i++){
    Date lDate = (Date)dates.get(i);
    String ds = formatter.format(lDate);    
    System.out.println("Date is ..." + ds);
    //Write your code for storing dates to list
}

If you want to do it using .map() or just want to know how it works you can do it like this:

var added=false;
$.map(arr, function(elementOfArray, indexInArray) {
 if (elementOfArray.id == productID) {
   elementOfArray.price = productPrice;
   added = true;
 }
}
if (!added) {
  arr.push({id: productID, price: productPrice})
}

The function handles each element separately. The .inArray() proposed in other answers is probably the more efficient way to do it.

                                      );
            foreach (var item in CompanyDetails)
            {
                Console.WriteLine(item.TypeOfInvestment.PadRight(20) + " " + item.Balance.ToString());
            }
            Console.ReadLine();

        }

Plain Old Data

In short, it is all built-in data types (e.g. int, char, float, long, unsigned char, double, etc.) and all aggregation of POD data. Yes, it's a recursive definition. ;)

To be more clear, a POD is what we call "a struct": a unit or a group of units that just store data.

Other way :

zeroos="000"
echo 

for num in {99..105};do
 echo ${zeroos:${#num}:${#zeroos}}${num}
done

So simple function to convert any number would be:

function leading_zero(){

    local num=$1
    local zeroos=00000
    echo ${zeroos:${#num}:${#zeroos}}${num} 

}

I fixed it. My actual image file name had spaces in it, and for whatever reason Angular did not like that. When I removed the spaces from my file name, assets/images/myimage.png worked.

We can do it in two ways:

1. When the user comes on https://bskud.com/PINCODE/BIHAR/index.php then redirect to https://bskud.com/PINCODE/BIHAR.php

   By the below PHP code

   <?php
       header("Location: https://bskud.com/PINCODE/BIHAR.php");
       exit;
   ?>
   

   Save the above code in https://bskud.com/PINCODE/BIHAR/index.php

2. When any condition is true then redirect to another page:

   <?php
       $myVar = "bskud";
       if ($myVar == "bskud") {
   ?>
   
   <script> window.location.href="https://bskud.com";  </script>
   
   <?php
       }
       else {
           echo "<b>Check the website name again</b>";
       }
   ?>
   

This example puts your JSON into proper format and does an existence check. I use jquery for convenience.

http://jsfiddle.net/nXFxC/

<!-- HTML -->
<span id="test">Hello</span><br>
<span id="test2">Hello</span>

//Javascript

$(document).ready(function(){
    var JSON = {"animals":[{"name":"cat"}, {"name":"dog"}]};

if(JSON.animals[1].name){      
$("#test").html("It exists");
}
if(!JSON.animals[2]){       
$("#test2").html("It doesn't exist");
}
});

One approach that works from pretty much anywhere, including from places where you don't have an Activity or View, is to grab a Handler to the main thread and show the toast:

public void toast(final Context context, final String text) {
  Handler handler = new Handler(Looper.getMainLooper());
  handler.post(new Runnable() {
    public void run() {
      Toast.makeText(context, text, Toast.LENGTH_LONG).show();
    }
  });
}

The advantage of this approach is that it works with any Context, including Service and Application.

Concatenate with & operator

Dim str as String  'no need to create a string instance
str = "Hello " & "World"

You can concate with the + operator as well but you can get yourself into trouble when trying to concatenate numbers.

Concatenate with String.Concat()

str = String.Concat("Hello ", "World")

Useful when concatenating array of strings

StringBuilder.Append()

When concatenating large amounts of strings use StringBuilder, it will result in much better performance.

    Dim sb as new System.Text.StringBuilder()
    str = sb.Append("Hello").Append(" ").Append("World").ToString()

Strings in .NET are immutable, resulting in a new String object being instantiated for every concatenation as well a garbage collection thereof.

This is how I rotate 360 in right direction.

[UIView animateWithDuration:1.0f delay:0.0f options:UIViewAnimationOptionRepeat|UIViewAnimationOptionCurveLinear
                     animations:^{
                         [imageIndView setTransform:CGAffineTransformRotate([imageIndView transform], M_PI-0.00001f)];
                     } completion:nil];

I came across this method and I use it to make div IDs the slug name inside the loop:

<?php $slug = basename( get_permalink() ); echo $slug;?>

The same notation is used for pointing at a single character or the first character of a null-terminated string:

char c = 'Z';
char a[] = "Hello world";

char *ptr1 = &c;
char *ptr2 = a;      // Points to the 'H' of "Hello world"
char *ptr3 = &a[0];  // Also points to the 'H' of "Hello world"
char *ptr4 = &a[6];  // Points to the 'w' of "world"
char *ptr5 = a + 6;  // Also points to the 'w' of "world"

The values in ptr2 and ptr3 are the same; so are the values in ptr4 and ptr5. If you're going to treat some data as a string, it is important to make sure it is null terminated, and that you know how much space there is for you to use. Many problems are caused by not understanding what space is available and not knowing whether the string was properly null terminated.

Note that all the pointers above can be dereferenced as if they were an array:

 *ptr1    == 'Z'
  ptr1[0] == 'Z'

 *ptr2    == 'H'
  ptr2[0] == 'H'
  ptr2[4] == 'o'

 *ptr4    == 'w'
  ptr4[0] == 'w'
  ptr4[4] == 'd'

  ptr5[0] ==   ptr3[6]
*(ptr5+0) == *(ptr3+6)

Late addition to question

What does char (*ptr)[N]; represent?

This is a more complex beastie altogether. It is a pointer to an array of N characters. The type is quite different; the way it is used is quite different; the size of the object pointed to is quite different.

char (*ptr)[12] = &a;

(*ptr)[0] == 'H'
(*ptr)[6] == 'w'

*(*ptr + 6) == 'w'

Note that ptr + 1 points to undefined territory, but points 'one array of 12 bytes' beyond the start of a. Given a slightly different scenario:

char b[3][12] = { "Hello world", "Farewell", "Au revoir" };

char (*pb)[12] = &b[0];

Now:

(*(pb+0))[0] == 'H'
(*(pb+1))[0] == 'F'
(*(pb+2))[5] == 'v'

You probably won't come across pointers to arrays except by accident for quite some time; I've used them a few times in the last 25 years, but so few that I can count the occasions on the fingers of one hand (and several of those have been answering questions on Stack Overflow). Beyond knowing that they exist, that they are the result of taking the address of an array, and that you probably didn't want it, you don't really need to know more about pointers to arrays.

TL;DR

The difference between the commands is that one provides you with a tag message while the other doesn't. An annotated tag has a message that can be displayed with git-show(1), while a tag without annotations is just a named pointer to a commit.

More About Lightweight Tags

According to the documentation: "To create a lightweight tag, don’t supply any of the -a, -s, or -m options, just provide a tag name". There are also some different options to write a message on annotated tags:

• When you use git tag <tagname>, Git will create a tag at the current revision but will not prompt you for an annotation. It will be tagged without a message (this is a lightweight tag).
• When you use git tag -a <tagname>, Git will prompt you for an annotation unless you have also used the -m flag to provide a message.
• When you use git tag -a -m <msg> <tagname>, Git will tag the commit and annotate it with the provided message.
• When you use git tag -m <msg> <tagname>, Git will behave as if you passed the -a flag for annotation and use the provided message.

Basically, it just amounts to whether you want the tag to have an annotation and some other information associated with it or not.

On distributions that come with the open command,

If you were using IBM Informix Dynamic Server, you would have a MONEY type which is a minor variant on the DECIMAL or NUMERIC type. It is always a fixed-point type (whereas DECIMAL can be a floating point type). You can specify a scale from 1 to 32, and a precision from 0 to 32 (defaulting to a scale of 16 and a precision of 2). So, depending on what you need to store, you might use DECIMAL(16,2) - still big enough to hold the US Federal Deficit, to the nearest cent - or you might use a smaller range, or more decimal places.

Some people seem to turn autoescape off which carries security risks to manipulate the string display.

If you only want to insert some linebreaks into a string and convert the linebreaks into <br />, then you could take a jinja macro like:

{% macro linebreaks_for_string( the_string ) -%}
{% if the_string %}
{% for line in the_string.split('\n') %}
<br />
{{ line }}
{% endfor %}
{% else %}
{{ the_string }}
{% endif %}
{%- endmacro %}

and in your template just call this with

{{ linebreaks_for_string( my_string_in_a_variable ) }}

Another solution for the original question, esp. useful if you want to remove only SOME of the older files in a folder, would be smth like this:

find . -name "*.sess" -mtime +100 

and so on.. Quotes block shell wildcards, thus allowing you to "find" millions of files :)

With Yglu Structural Templating, your example can be written:

foo: !()
  !? $.propname: 
     type: number 
     default: !? $.default

bar:
  !apply .foo: 
    propname: "some_prop"
    default: "some default"

You can generate an AWR (automatic workload repository) report from the database.

Run from the SQL*Plus command line:

SQL> @$ORACLE_HOME/rdbms/admin/awrrpt.sql

Read the document related to how to generate & understand an AWR report. It will give a complete view of database performance and resource issues. Once we are familiar with the AWR report it will be helpful to find Top SQL which is consuming resources.

Also, in the 12C EM Express UI we can generate an AWR.

I have solved the issue by the following way.

1. Creating a class . The class has some empty implementations

class MyTrustManager implements X509TrustManager {
public java.security.cert.X509Certificate[] getAcceptedIssuers() {
    return null;
}

public void checkClientTrusted(X509Certificate[] certs, String authType) {
}

public void checkServerTrusted(X509Certificate[] certs, String authType) {
}

@Override
public void checkClientTrusted(java.security.cert.X509Certificate[] paramArrayOfX509Certificate, String paramString)
        throws CertificateException {
    // TODO Auto-generated method stub

}

@Override
public void checkServerTrusted(java.security.cert.X509Certificate[] paramArrayOfX509Certificate, String paramString)
        throws CertificateException {
    // TODO Auto-generated method stub

}

2. Creating a method

private static void disableSSL() {
    try {
        TrustManager[] trustAllCerts = new TrustManager[] { new MyTrustManager() };

        // Install the all-trusting trust manager
        SSLContext sc = SSLContext.getInstance("SSL");
        sc.init(null, trustAllCerts, new java.security.SecureRandom());
        HostnameVerifier allHostsValid = new HostnameVerifier() {
            public boolean verify(String hostname, SSLSession session) {
                return true;
            }
        };
        HttpsURLConnection.setDefaultHostnameVerifier(allHostsValid);
        HttpsURLConnection.setDefaultSSLSocketFactory(sc.getSocketFactory());
    } catch (Exception e) {
        e.printStackTrace();
    }
}

3. Call the disableSSL() method where the exception is thrown. It worked fine.

I would expect either:

// Makes sure item is at newIndex after the operation
T item = list[oldIndex];
list.RemoveAt(oldIndex);
list.Insert(newIndex, item);

... or:

// Makes sure relative ordering of newIndex is preserved after the operation, 
// meaning that the item may actually be inserted at newIndex - 1 
T item = list[oldIndex];
list.RemoveAt(oldIndex);
newIndex = (newIndex > oldIndex ? newIndex - 1, newIndex)
list.Insert(newIndex, item);

... would do the trick, but I don't have VS on this machine to check.

On mac and sublime text 3 , which version is 3103, the content should be

{
    "shell_cmd": "open -a 'Google Chrome' '$file'"
}

Not sure if this is any "cleaner", but:

List keys = new ArrayList(map.keySet());
for (int i = 0; i < keys.size(); i++) {
    Object obj = keys.get(i);
    // do stuff here
}

If you need to pass data from one controller to another you must pass data by route values.Because both are different request.if you send data from one page to another then you have to user query string(same as route values).

But you can do one trick :

In your calling action call the called action as a simple method :

public class ServerController : Controller
{
 [HttpPost]
 public ActionResult ApplicationPoolsUpdate(ServiceViewModel viewModel)
 {
      XDocument updatedResultsDocument = myService.UpdateApplicationPools();
      ApplicationPoolController pool=new ApplicationPoolController(); //make an object of ApplicationPoolController class.

      return pool.UpdateConfirmation(updatedResultsDocument); // call the ActionMethod you want as a simple method and pass the model as an argument.
      // Redirect to ApplicationPool controller and pass
      // updatedResultsDocument to be used in UpdateConfirmation action method
 }
}

When you are trying to prevent XSS, it's important to think of the context. As an example how and what to escape is very different if you are ouputting data inside a variable in a javascript snippet as opposed to outputting data in an HTML tag or an HTML attribute.

I have an example of this here: http://erlend.oftedal.no/blog/?blogid=91

Also checkout the OWASP XSS Prevention Cheat Sheet: http://www.owasp.org/index.php/XSS_%28Cross_Site_Scripting%29_Prevention_Cheat_Sheet

So the short answer is, make sure you escape output like suggested by Tendayi Mawushe, but take special care when you are outputting data in HTML attributes or javascript.

Use this snippet:

@echo off
echo something
echo.
echo press enter to exit
pause >nul
exit

Not sure it stands for anything special. It's just a convention that you supply an 'all' rule, and generally it's used to list all the sub-targets needed to build the entire project, hence the name 'all'. The only thing special about it is that often times people will put it in as the first target in the makefile, which means that just typing 'make' alone will do the same thing as 'make all'.

You may get your answer here: Get-WmiObject : The RPC server is unavailable. (Exception from HRESULT: 0x800706BA)

UPDATE

It might be due to various issues.I cant say which one is there in your case. It may be because:

• DCOM is not enabled in host pc or target pc or on both
• your firewall or even your antivirus is preventing the access
• any WMI related service is disabled

Some WMI related services are:

• Remote Access Auto Connection Manager
• Remote Access Connection Manager
• Remote Procedure Call (RPC)
• Remote Procedure Call (RPC) Locator
• Remote Registry

For DCOM settings refer to registry key HKLM\Software\Microsoft\OLE, value EnableDCOM. The value should be set to 'Y'.

In general, no. However, a struct declared as file-scope or static in a function /will/ be initialized to 0 (just like all other variables of those scopes):

int x; // 0
int y = 42; // 42
struct { int a, b; } foo; // 0, 0

void foo() {
  struct { int a, b; } bar; // undefined
  static struct { int c, d; } quux; // 0, 0
}

In case you're using TortoiseSVN and the file is already commited, go to your files project folder, right click on the file/folder you want to ignore, TortoiseSVN -> Unversion and add to ignore list. Then you delete the folder/file (click on it and then push DELETE on your keyboard), right click on your project folder, -> SVN Commit... This will delete the folder from the repository.... Now you can create your folder/file again and then it will be ignored.

Use max-width on the images too. Change:

.erb-image-wrapper img{
    width:100% !important;
    height:100% !important;
    display:block;
}

to...

.erb-image-wrapper img{
    max-width:100% !important;
    max-height:100% !important;
    display:block;
}

you can use this:

CREATE GLOBAL TEMPORARY TABLE Table_name
    (startdate DATE,
     enddate DATE,
     class CHAR(20))
  ON COMMIT DELETE ROWS;

Here are the different ways in which you can create an array of booleans in typescript:

let arr1: boolean[] = [];
let arr2: boolean[] = new Array();
let arr3: boolean[] = Array();

let arr4: Array<boolean> = [];
let arr5: Array<boolean> = new Array();
let arr6: Array<boolean> = Array();

let arr7 = [] as boolean[];
let arr8 = new Array() as Array<boolean>;
let arr9 = Array() as boolean[];

let arr10 = <boolean[]> [];
let arr11 = <Array<boolean>> new Array();
let arr12 = <boolean[]> Array();

let arr13 = new Array<boolean>();
let arr14 = Array<boolean>();

You can access them using the index:

console.log(arr[5]);

and you add elements using push:

arr.push(true);

When creating the array you can supply the initial values:

let arr1: boolean[] = [true, false];
let arr2: boolean[] = new Array(true, false);

I know this is and oldie but i had this issue recently with the latest versions of Tomcat and Eclipse on Windows 10.

It was a permissions issue. All i had to do was navigate to the Tomcat install directory and open the folder. I was prompted to access the folder as an Administrator.

After this the versions were recognised by Eclipse and I could add the new runtime.

I did it this way.

Create the directive

function finRepeat() {
    return function(scope, element, attrs) {
        if (scope.$last){
            // Here is where already executes the jquery
            $(document).ready(function(){
                $('.materialboxed').materialbox();
                $('.tooltipped').tooltip({delay: 50});
            });
        }
    }
}

angular
    .module("app")
    .directive("finRepeat", finRepeat);

After you add it on the label where this ng-repeat

<ul>
    <li ng-repeat="(key, value) in data" fin-repeat> {{ value }} </li>
</ul>

And ready with that will be run at the end of the ng-repeat.

This is how you do it in your $(document).ready() function with FontAwesome Icons:

 $( ".owl-prev").html('<i class="fa fa-chevron-left"></i>');
 $( ".owl-next").html('<i class="fa fa-chevron-right"></i>');

before start make sure of installation:

yum install -y xorg-x11-server-Xorg xorg-x11-xauth xorg-x11-apps

1. start xming or cygwin
2. make connection with X11 forwarding (in putty don't forget to set localhost:0.0 for X display location)
3. edit sshd.cong and restart

     cat /etc/ssh/sshd_config | grep X
                             X11Forwarding yes
                             X11DisplayOffset 10
AddressFamily inet

4. Without the X11 forwarding, you are subjected to the X11 SECURITY and then you must: authorize the remote server to make a connection with the local X Server using a method (for instance, the xhost command) set the display environment variable to redirect the output to the X server of your local computer. In this example: 192.168.2.223 is the IP of the server 192.168.2.2 is the IP of the local computer where the x server is installed. localhost can also be used.

blablaco@blablaco01 ~
$ xhost 192.168.2.223
192.168.2.223 being added to access control list

blablaco@blablaco01 ~
$ ssh -l root 192.168.2.223
[email protected] password:
Last login: Sat May 22 18:59:04 2010 from etcetc
[root@oel5u5 ~]# export DISPLAY=192.168.2.2:0.0
[root@oel5u5 ~]# echo $DISPLAY
192.168.2.2:0.0
[root@oel5u5 ~]# xclock&

Then the xclock application must launch.

Check it on putty or mobaxterm and don't check in remote desktop Manager software. Be careful for user that sudo in.

Not sure exactly what you try to denote with that syntax, but in almost all RDBMS-es you can use a subquery in the FROM clause (sometimes called an "inline-view"):

SELECT..
FROM (
     SELECT ...
     FROM ...
     ) my_select
WHERE ...

In advanced "enterprise" RDBMS-es (like oracle, SQL Server, postgresql) you can use common table expressions which allows you to refer to a query by name and reuse it even multiple times:

-- Define the CTE expression name and column list.
WITH Sales_CTE (SalesPersonID, SalesOrderID, SalesYear)
AS
-- Define the CTE query.
(
    SELECT SalesPersonID, SalesOrderID, YEAR(OrderDate) AS SalesYear
    FROM Sales.SalesOrderHeader
    WHERE SalesPersonID IS NOT NULL
)
-- Define the outer query referencing the CTE name.
SELECT SalesPersonID, COUNT(SalesOrderID) AS TotalSales, SalesYear
FROM Sales_CTE
GROUP BY SalesYear, SalesPersonID
ORDER BY SalesPersonID, SalesYear;

(example from http://msdn.microsoft.com/en-us/library/ms190766(v=sql.105).aspx)

Try http://www.sql-server-helper.com/tips/date-formats.aspx. Lists all formats needed. In this case select Convert(varchar(10),CONVERT(date,YourDateColumn,106),103) change 103 to 104 id you need dd.mm.yyyy

Ok, I am definitively late to the party but if you are still looking for an optimal solution I would use the following ( for Java 8 )

    Charset inputCharset = Charset.forName("ISO-8859-1");
    Path pathToFile = ....
    try (BufferedReader br = Files.newBufferedReader( pathToFile, inputCharset )) {
        ...
     }

You have to set setOnItemLongClickListener() in the ListView:

lv.setOnItemLongClickListener(new OnItemLongClickListener() {
            @Override
            public boolean onItemLongClick(AdapterView<?> arg0, View arg1,
                    int pos, long id) {
                // TODO Auto-generated method stub

                Log.v("long clicked","pos: " + pos);

                return true;
            }
        }); 

The XML for each item in the list (should you use a custom XML) must have android:longClickable="true" as well (or you can use the convenience method lv.setLongClickable(true);). This way you can have a list with only some items responding to longclick.

Hope this will help you.

Complementing Carl Meyer, you can make a context processor like this:

module.context_processors.py

from django.conf import settings

def site(request):
    return {'SITE_URL': settings.SITE_URL}

local settings.py

SITE_URL = 'http://google.com' # this will reduce the Sites framework db call.

settings.py

TEMPLATE_CONTEXT_PROCESSORS = (
    ...
    "module.context_processors.site",
    ....
 )

templates returning context instance the url site is {{ SITE_URL }}

you can write your own rutine if want to handle subdomains or SSL in the context processor.

You are casting ClientID to char* causing the function to assume its a null terinated char array, which it is not.

from cplusplus.com :

string& append ( const char * s ); Appends a copy of the string formed by the null-terminated character sequence (C string) pointed by s. The length of this character sequence is determined by the first ocurrence of a null character (as determined by traits.length(s)).

You can also setup the environment in visual studio code. Run Ctrl + Shift + P, Then type ctr in the box that appears and select tasks:Configure Task Runner, Then change the task.json file to this: { "version": "0.1.0", "command": "explorer", "windows": { "command": "explorer.exe" }, "args": ["index.html"] }, save your changes, Then select your index.html file and type Ctrl + Shift + B. This will open the project with your default browser.

I got this to work:

explicit conversion

    public override object ReadJson(JsonReader reader, Type objectType, object existingValue,
                                    JsonSerializer serializer)
    {
        var jsonObj = serializer.Deserialize<List<SomeObject>>(reader);
        var conversion = jsonObj.ConvertAll((x) => x as ISomeObject);

        return conversion;
    }

Using Date pattern yyyy-MM-dd'T'HH:mm:ss.SSS'Z' and Java 8 you could do

String string = "2018-04-10T04:00:00.000Z";
DateTimeFormatter formatter = DateTimeFormatter.ofPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'", Locale.ENGLISH);
LocalDate date = LocalDate.parse(string, formatter);
System.out.println(date);

Update: For pre 26 use Joda time

String string = "2018-04-10T04:00:00.000Z";
DateTimeFormatter formatter = DateTimeFormat.forPattern("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'");
LocalDate date = org.joda.time.LocalDate.parse(string, formatter);

In app/build.gradle file, add like this-

dependencies {    
    compile 'joda-time:joda-time:2.9.4'
}

If you have a newer distro with a newer systemd (systemd version 236 or newer), you can set the values of StandardOutput or StandardError to file:YOUR_ABSPATH_FILENAME.

Long story:

In newer versions of systemd there is a relatively new option (the github request is from 2016 ish and the enhancement is merged/closed 2017 ish) where you can set the values of StandardOutput or StandardError to file:YOUR_ABSPATH_FILENAME. The file:path option is documented in the most recent systemd.exec man page.

This new feature is relatively new and so is not available for older distros like centos-7 (or any centos before that).

There are two ways to get this done either using JavaScript or jQuery.

JavaScript:

var getValue = document.getElementById('ddlViewBy').selectedOptions[0].value;

alert (getValue); // This will output the value selected.

OR

var ddlViewBy = document.getElementById('ddlViewBy');

var value = ddlViewBy.options[ddlViewBy.selectedIndex].value;

var text = ddlViewBy.options[ddlViewBy.selectedIndex].text;

alert (value); // This will output the value selected

alert (text); // This will output the text of the value selected

jQuery:

$("#ddlViewBy:selected").text(); // Text of the selected value

$("#ddlViewBy").val(); // Outputs the value of the ID in 'ddlViewBy'

If you need a laymans explanation of the use beyond that provided in the Spring Docs

Consider this code...

class Service {
    @Transactional(propagation=Propagation.REQUIRED)
    public void doSomething() {
        // access a database using a DAO
    }
}

When doSomething() is called it knows it has to start a Transaction on the database before executing. If the caller of this method has already started a Transaction then this method will use that same physical Transaction on the current database connection.

This @Transactional annotation provides a means of telling your code when it executes that it must have a Transaction. It will not run without one, so you can make this assumption in your code that you wont be left with incomplete data in your database, or have to clean something up if an exception occurs.

Transaction management is a fairly complicated subject so hopefully this simplified answer is helpful

As mentioned by @physicsGuy above, You can use the hinterland extension. Simple steps to do it.

Installing nbextension using conda forge channel. Simply run the below command in conda terminal:

conda install -c conda-forge jupyter_nbextensions_configurator

Next Step enabling the hinterland extension. Run the below command in conda terminal:

jupyter nbextension enable hinterland/hinterland

That's it, done.

I just started learning React today and was facing the same problem. Below is the code I had written.

<script type="text/babel">
    class Hello extends React.Component {
        render(){
            return (
                <div>
                    <h1>Hello World</h1>
                </div>
            )
        }
    }
    ReactDOM.render(
        <Hello/>
        document.getElementById('react-container')
    )


</script>

And as you can see that I had missed a comma (,) after I use <Hello/>. And error itself is saying on which line we need to look.

So once I add a comma before the second parameter for the ReactDOM.render() function, all started working fine.

Thanks to CSS3 there is a solution !

The solution is to put the image as background-image and then set the background-size to contain.

HTML

<div class='bounding-box'>
</div>

CSS

.bounding-box {
  background-image: url(...);
  background-repeat: no-repeat;
  background-size: contain;
}

Test it here: http://www.w3schools.com/cssref/playit.asp?filename=playcss_background-size&preval=contain

Full compatibility with latest browsers: http://caniuse.com/background-img-opts

To align the div in the center, you can use this variation:

.bounding-box {
  background-image: url(...);
  background-size: contain;
  position: absolute;
  background-position: center;
  background-repeat: no-repeat;
  height: 100%;
  width: 100%;
}

As an addendum, if you want to reapply your changes on top of the remote, you can also try:

git pull --rebase origin master

If you then want to undo some of your changes (but perhaps not all of them) you can use:

git reset SHA_HASH

Then do some adjustment and recommit.

There are two major options in matplotlib (pylab) to control the image size:

1. You can set the size of the resulting image in inches
2. You can define the DPI (dots per inch) for output file (basically, it is a resolution)

Normally, you would like to do both, because this way you will have full control over the resulting image size in pixels. For example, if you want to render exactly 800x600 image, you can use DPI=100, and set the size as 8 x 6 in inches:

import matplotlib.pyplot as plt
# plot whatever you need...
# now, before saving to file:
figure = plt.gcf() # get current figure
figure.set_size_inches(8, 6)
# when saving, specify the DPI
plt.savefig("myplot.png", dpi = 100)

One can use any DPI. In fact, you might want to play with various DPI and size values to get the result you like the most. Beware, however, that using very small DPI is not a good idea, because matplotlib may not find a good font to render legend and other text. For example, you cannot set the DPI=1, because there are no fonts with characters rendered with 1 pixel :)

From other comments I understood that other issue you have is proper text rendering. For this, you can also change the font size. For example, you may use 6 pixels per character, instead of 12 pixels per character used by default (effectively, making all text twice smaller).

import matplotlib
#...
matplotlib.rc('font', size=6)

Finally, some references to the original documentation: http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.savefig, http://matplotlib.sourceforge.net/api/pyplot_api.html#matplotlib.pyplot.gcf, http://matplotlib.sourceforge.net/api/figure_api.html#matplotlib.figure.Figure.set_size_inches, http://matplotlib.sourceforge.net/users/customizing.html#dynamic-rc-settings

P.S. Sorry, I didn't use pylab, but as far as I'm aware, all the code above will work same way in pylab - just replace plt in my code with the pylab (or whatever name you assigned when importing pylab). Same for matplotlib - use pylab instead.

Checkout the ByteSize library. It's the System.TimeSpan for bytes!

It handles the conversion and formatting for you.

var maxFileSize = ByteSize.FromKiloBytes(10);
maxFileSize.Bytes;
maxFileSize.MegaBytes;
maxFileSize.GigaBytes;

It also does string representation and parsing.

// ToString
ByteSize.FromKiloBytes(1024).ToString(); // 1 MB
ByteSize.FromGigabytes(.5).ToString();   // 512 MB
ByteSize.FromGigabytes(1024).ToString(); // 1 TB

// Parsing
ByteSize.Parse("5b");
ByteSize.Parse("1.55B");

if Data frame look like that:

group         name      count
fruit         apple     90
fruit         banana    150
fruit         orange    130
vegetable     broccoli  80
vegetable     kale      70
vegetable     lettuce   125

and OUTPUT could be like

   group    name  count
0  fruit   apple     90
1  fruit  banana    150
2  fruit  orange    130

if you use logical operator np.logical_not

df[np.logical_not(df['group'] == 'vegetable')]

more about

https://docs.scipy.org/doc/numpy-1.13.0/reference/routines.logic.html

other logical operators

1. logical_and(x1, x2, /[, out, where, ...]) Compute the truth value of x1 AND x2 element-wise.

2. logical_or(x1, x2, /[, out, where, casting, ...]) Compute the truth value of x1 OR x2 element-wise.

3. logical_not(x, /[, out, where, casting, ...]) Compute the truth value of NOT x element-wise.
4. logical_xor(x1, x2, /[, out, where, ..]) Compute the truth value of x1 XOR x2, element-wise.

from manual:

: [arguments] No effect; the command does nothing beyond expanding arguments and performing any specified redirections. A zero exit code is returned.

As this returns always zero therefore is is similar to be used as true

Check out this answer: What Is the Purpose of the `:' (colon) GNU Bash Builtin?

The hash is never sent to the server, so no.

What you mean to do is:

jQuery(this).prev("li").attr("id", "newID");

That will set the ID to the new ID

var depthead = (from s in db.M_Users
                  join m in db.M_User_Types on s.F_User_Type equals m.UserType_Id
                  where m.UserType_Name.ToUpper().Trim().Contains("DEPARTMENT HEAD")
                  select new {s.FullName,s.F_User_Type,s.userId,s.UserCode } 
               ).OrderBy(d => d.userId).ToList();

Model.AvailableDeptHead.Add(new SelectListItem { Text = "Select", Value = "0" });
for (int i = 0; i < depthead.Count; i++)
    Model.AvailableDeptHead.Add(new SelectListItem { Text = depthead[i].UserCode + " - " + depthead[i].FullName, Value = Convert.ToString(depthead[i].userId) });

A pointer-to-member allows you to write a single comparator, which can work with any data member of your class:

#include <algorithm>
#include <vector>
#include <string>
#include <iostream>

template <typename T, typename U>
struct CompareByMember {
    // This is a pointer-to-member, it represents a member of class T
    // The data member has type U
    U T::*field;
    CompareByMember(U T::*f) : field(f) {}
    bool operator()(const T &lhs, const T &rhs) {
        return lhs.*field < rhs.*field;
    }
};

struct Test {
    int a;
    int b;
    std::string c;
    Test(int a, int b, std::string c) : a(a), b(b), c(c) {}
};

// for convenience, this just lets us print out a Test object
std::ostream &operator<<(std::ostream &o, const Test &t) {
    return o << t.c;
}

int main() {
    std::vector<Test> vec;
    vec.push_back(Test(1, 10, "y"));
    vec.push_back(Test(2, 9, "x"));

    // sort on the string field
    std::sort(vec.begin(), vec.end(), 
        CompareByMember<Test,std::string>(&Test::c));
    std::cout << "sorted by string field, c: ";
    std::cout << vec[0] << " " << vec[1] << "\n";

    // sort on the first integer field
    std::sort(vec.begin(), vec.end(), 
        CompareByMember<Test,int>(&Test::a));
    std::cout << "sorted by integer field, a: ";
    std::cout << vec[0] << " " << vec[1] << "\n";

    // sort on the second integer field
    std::sort(vec.begin(), vec.end(), 
        CompareByMember<Test,int>(&Test::b));
    std::cout << "sorted by integer field, b: ";
    std::cout << vec[0] << " " << vec[1] << "\n";
}

Output:

sorted by string field, c: x y
sorted by integer field, a: y x
sorted by integer field, b: x y

Try to play around also with the calc and overflow functions

.myClassName {
    overflow: auto;
    height: calc(100% - 1.5em);
}

Ubuntu these days comes with ufw - Uncomplicated Firewall. ufw is an easy-to-use method of handling iptables rules.

Try using this command to allow a port

sudo ufw allow 1701

To test connectivity, you could try shutting down the VPN software (freeing up the ports) and using netcat to listen, like this:

nc -l 1701

Then use telnet from your Windows host and see what shows up on your Ubuntu terminal. This can be repeated for each port you'd like to test.

Finally after comparing all solution, I think starting from build.gradle file can be convenient.

Gradle distribution has samples folder with a lot of examples, and there is gradle init --type basic comand see Chapter 47. Build Init Plugin. But they all needs some editing.

You can use template below as well, then run gradle initSourceFolders eclipse

/*
* Nodeclipse/Enide build.gradle template for basic Java project
*   https://github.com/Nodeclipse/nodeclipse-1/blob/master/org.nodeclipse.enide.editors.gradle/docs/java/basic/build.gradle
* Initially asked on
*   http://stackoverflow.com/questions/14017364/how-to-create-java-gradle-project
* Usage
*   1. create folder (or general Eclipse project) and put this file inside
*   2. run `gradle initSourceFolders eclipse` or `gradle initSourceFolders idea`
* @author Paul Verest; 
* based on `gradle init --type basic`, that does not create source folders 
*/

apply plugin: 'java'
apply plugin: 'eclipse'
apply plugin: 'idea'

task initSourceFolders { // add << before { to prevent executing during configuration phase
   sourceSets*.java.srcDirs*.each { it.mkdirs() }
   sourceSets*.resources.srcDirs*.each { it.mkdirs() }
}

task wrapper(type: Wrapper) {
    gradleVersion = '1.11'
}

// In this section you declare where to find the dependencies of your project
repositories {
    // Use Maven Central for resolving your dependencies.
    // You can declare any Maven/Ivy/file repository here.
    mavenCentral()
}

// In this section you declare the dependencies for your production and test code
dependencies {
    //compile fileTree(dir: 'libs', include: '*.jar')
    // The production code uses the SLF4J logging API at compile time
    //compile 'org.slf4j:slf4j-api:1.7.5'

    // Declare the dependency for your favourite test framework you want to use in your tests.
    // TestNG is also supported by the Gradle Test task. Just change the
    // testCompile dependency to testCompile 'org.testng:testng:6.8.1' and add
    // 'test.useTestNG()' to your build script.
    testCompile "junit:junit:4.11"
}

The result is like below.

That can be used without any Gradle plugin for Eclipse,
or with (Enide) Gradle for Eclipse, Jetty, Android alternative to Gradle Integration for Eclipse

https://github.com/requery/sqlite-android allows you to query JSON fields (and arrays in them, I've tried it and am using it). Before that I was just storing JSON strings into a TEXT column. It supports FTS3, FTS4, & JSON1

As of July 2019, it still gets version bumps every now and then, so it isn't a dead project.

• https://www.sqlite.org/json1.html (store and query JSON documents)
• https://www.sqlite.org/fts3.html (perform full-text searches)
