I could not get this working with the accepted answer, mainly because I did not know where to enter that code. I looked everywhere for some explanation of the URL Rewrite tool that made sense, but could not find any. I ended up using the HTTP Redirect tool in IIS.

1. Choose your site
2. Click HTTP Redirect in the IIS section (Make sure the Role Service is installed)
3. Check "Redirect requests to this destination"
4. Enter where you want to redirect. In your case "wwww.mysite.com/menu_1/MainScreen.aspx"
5. In Redirect Behavior, I found I had to check "Only redirect requests to content in this directory (not subdirectories), or it would go into a loop. See what works for you.

Hope this helps.

As noted in Chris Dolan's and Wilbert's answers, PS1 slows you down.

Rather than completely disabling (as suggested by Dolan) or using the script offered by Wilbert, I use a "dumb PS1" that is much faster.

It uses (git symbolic-ref -q HEAD || git rev-parse --short HEAD) 2> /dev/null:

PS1='\033[33m\]\w \n\[\033[32m\]$((git symbolic-ref -q HEAD || git rev-parse -q --short HEAD) 2> /dev/null) \[\033[00m\]# '

On my Cygwin, this is faster than Wilbert's "fast_Git_PS1" answer - 200 ms vs. 400 ms, so it shaves off a bit of your prompt sluggishness.

It isn't as sophisticated as __git_ps1 - for example it doesn't change the prompt when you cd into the .git directory, etc. but for normal everyday use it's good enough and fast.

This was tested on Git 1.7.9 (Cygwin, but it should work on any platform).

Angular is based on observable instead of promise base as of angularjs 1.x, so when we try to get data using http it returns observable instead of promise, like you did

 return this.http
      .get(this.configEndPoint)
      .map(res => res.json());

then to get data and show on view we have to convert it into desired form using RxJs functions like .map() function and .subscribe()

.map() is used to convert the observable (received from http request)to any form like .json(), .text() as stated in Angular's official website,

.subscribe() is used to subscribe those observable response and ton put into some variable so from which we display it into the view

this.myService.getConfig().subscribe(res => {
   console.log(res);
   this.data = res;
});

Something simpler than what @Milen proposed but it gives YYYY-MM-DD instead of the DD-MM-YYYY you wanted :

SUBSTRING((DT_STR,30, 1252) GETDATE(), 1, 10)

Expression builder screen:

CLOCK_REALTIME represents the machine's best-guess as to the current wall-clock, time-of-day time. As Ignacio and MarkR say, this means that CLOCK_REALTIME can jump forwards and backwards as the system time-of-day clock is changed, including by NTP.

CLOCK_MONOTONIC represents the absolute elapsed wall-clock time since some arbitrary, fixed point in the past. It isn't affected by changes in the system time-of-day clock.

If you want to compute the elapsed time between two events observed on the one machine without an intervening reboot, CLOCK_MONOTONIC is the best option.

Note that on Linux, CLOCK_MONOTONIC does not measure time spent in suspend, although by the POSIX definition it should. You can use the Linux-specific CLOCK_BOOTTIME for a monotonic clock that keeps running during suspend.

Copying file to host: scp SourceFile remoteuser@remotehost:/directory/TargetFile

Copying file from host: scp user@host:/directory/SourceFile TargetFile

Copying directory recursively from host: scp -r user@host:/directory/SourceFolder TargetFolder

NOTE: If the host is using a port other than port 22, you can specify it with the -P option: scp -P 2222 user@host:/directory/SourceFile TargetFile

If you need to convert a string to a DateTime you could try

DateTime dt = DateTime.Parse("01:00 PM"); // No error checking

or (with error checking)

DateTime dt;
bool res = DateTime.TryParse("01:00 PM", out dt);

Variable dt contains your datetime, so you can write it

dt.ToString("HH:mm");

Last one works for every DateTime var you have, so if you still have a DateTime, you can write it out in this way.

Purpose of view is displaying model. You should use controller to redirect request before creating model and passing it to view. Use Controller.RedirectToAction method for this.

Here is an implementation that streams the file's content out without buffering it (buffering in byte[] / MemoryStream, etc. can be a server problem if it's a big file).

public class FileResult : IHttpActionResult
{
    public FileResult(string filePath)
    {
        if (filePath == null)
            throw new ArgumentNullException(nameof(filePath));

        FilePath = filePath;
    }

    public string FilePath { get; }

    public Task<HttpResponseMessage> ExecuteAsync(CancellationToken cancellationToken)
    {
        var response = new HttpResponseMessage(HttpStatusCode.OK);
        response.Content = new StreamContent(File.OpenRead(FilePath));
        var contentType = MimeMapping.GetMimeMapping(Path.GetExtension(FilePath));
        response.Content.Headers.ContentType = new MediaTypeHeaderValue(contentType);
        return Task.FromResult(response);
    }
}

It can be simply used like this:

public class MyController : ApiController
{
    public IHttpActionResult Get()
    {
        string filePath = GetSomeValidFilePath();
        return new FileResult(filePath);
    }
}

string stringtodate = ((DateTime)row.Cells[4].Value).ToString("MM-dd-yyyy");
textBox9.Text = stringtodate;

The most straight-forward way I can think of is using numpy's gradient function:

x = numpy.linspace(0,10,1000)
dx = x[1]-x[0]
y = x**2 + 1
dydx = numpy.gradient(y, dx)

This way, dydx will be computed using central differences and will have the same length as y, unlike numpy.diff, which uses forward differences and will return (n-1) size vector.

As suggested here by @0x7fffffff, if you have UINavigationController it can be easier to do:

YourViewController *rootController =
    (YourViewController *)
        [self.navigationController.viewControllers objectAtIndex: 0];

The code in the answer above returns UINavigation controller (if you have it) and if this is what you need, you can use self.navigationController.

I've just run into this issue and it was because I had updated a view in my DB and not refreshed the schema in my mapping.

var fs = File.Open("file.name", FileMode.OpenOrCreate, FileAccess.ReadWrite);
var sw = new StreamWriter(fs);
var sr = new StreamReader(fs);

...

fs.Close();
//or sw.Close();

The key thing is to open the file with the FileAccess.ReadWrite flag. You can then create whatever Stream/String/Binary Reader/Writers you need using the initial FileStream.

For the sake of completeness, first make sure you have the correct import so you can use the addRow function:

import javax.swing.table.*;

Assuming your jTable is already created, you can proceed and create your own add row method which will accept the parameters that you need:

public void yourAddRow(String str1, String str2, String str3){
  DefaultTableModel yourModel = (DefaultTableModel) yourJTable.getModel();
  yourModel.addRow(new Object[]{str1, str2, str3});
}

You can also use list.remove(a[0]) to pop out the first element in the list.

>>>> a=[1,2,3,4,5]
>>>> a.remove(a[0])
>>>> print a
>>>> [2,3,4,5]

Got into the same predicament. I ended up with the following. So here I am not injecting the scope object into the factory, but setting the $scope in the controller itself using the concept of promise returned by $http service.

(function () {
    getDataFactory = function ($http)
    {
        return {
            callWebApi: function (reqData)
            {
                var dataTemp = {
                    Page: 1, Take: 10,
                    PropName: 'Id', SortOrder: 'Asc'
                };

                return $http({
                    method: 'GET',
                    url: '/api/PatientCategoryApi/PatCat',
                    params: dataTemp, // Parameters to pass to external service
                    headers: { 'Content-Type': 'application/Json' }
                })                
            }
        }
    }
    patientCategoryController = function ($scope, getDataFactory) {
        alert('Hare');
        var promise = getDataFactory.callWebApi('someDataToPass');
        promise.then(
            function successCallback(response) {
                alert(JSON.stringify(response.data));
                // Set this response data to scope to use it in UI
                $scope.gridOptions.data = response.data.Collection;
            }, function errorCallback(response) {
                alert('Some problem while fetching data!!');
            });
    }
    patientCategoryController.$inject = ['$scope', 'getDataFactory'];
    getDataFactory.$inject = ['$http'];
    angular.module('demoApp', []);
    angular.module('demoApp').controller('patientCategoryController', patientCategoryController);
    angular.module('demoApp').factory('getDataFactory', getDataFactory);    
}());

onDestroy() is meant for final cleanup - freeing up resources that you can on your own,closing open connections,readers,writers,etc. If you don't override it, the system does what it has to.

on the other hand, finish() just lets the system know that the programmer wants the current Activity to be finished. And hence, it calls up onDestroy() after that.

Something to note:

it isn't necessary that only a call to finish() triggers a call to onDestroy(). No. As we know, the android system is free to kill activities if it feels that there are resources needed by the current Activity that are needed to be freed.

Underscore.js is a good library for these sorts of operations - it uses the builtin routines such as Array.filter if available, or uses its own if not.

http://documentcloud.github.com/underscore/

The docs will give an idea of use - the javascript lambda syntax is nowhere near as succinct as ruby or others (I always forget to add an explicit return statement for example) and scope is another easy way to get caught out, but you can do most things quite easily with the exception of constructs such as lazy list comprehensions.

From the docs for .select() (.filter() is an alias for the same)

Looks through each value in the list, returning an array of all the values that pass a truth test (iterator). Delegates to the native filter method, if it exists.

  var evens = _.select([1, 2, 3, 4, 5, 6], function(num){ return num % 2 == 0; });
  => [2, 4, 6]

The best cross-browser solution is

Within the body of a class, the class name isn't defined yet, so it is not available. Can you not simply type the name of the class? Maybe you need to say more about the problem so we can find a solution for you.

I would create a metaclass to do this work for you. It's invoked at class creation time (conceptually at the very end of the class: block), and can manipulate the class being created. I haven't tested this:

class InputAssigningMetaclass(type):
    def __new__(cls, name, bases, attrs):
        cls.input = get_input(name)
        return super(MyType, cls).__new__(cls, name, bases, newattrs)

class MyBaseFoo(object):
    __metaclass__ = InputAssigningMetaclass

class foo(MyBaseFoo):
    # etc, no need to create 'input'

class foo2(MyBaseFoo):
    # etc, no need to create 'input'

The third parameter of String.prototype.replace() function was never defined as a standard, so most browsers simply do not implement it.

The best way is to use regular expression with g (global) flag.

var myStr = 'this,is,a,test';_x000D_
var newStr = myStr.replace(/,/g, '-');_x000D_
_x000D_
console.log( newStr );  // "this-is-a-test"

Still have issues?

It is important to note, that regular expressions use special characters that need to be escaped. As an example, if you need to escape a dot (.) character, you should use /\./ literal, as in the regex syntax a dot matches any single character (except line terminators).

var myStr = 'this.is.a.test';_x000D_
var newStr = myStr.replace(/\./g, '-');_x000D_
_x000D_
console.log( newStr );  // "this-is-a-test"

If you need to pass a variable as a replacement string, instead of using regex literal you may create RegExp object and pass a string as the first argument of the constructor. The normal string escape rules (preceding special characters with \ when included in a string) will be necessary.

var myStr = 'this.is.a.test';_x000D_
var reStr = '\\.';_x000D_
var newStr = myStr.replace(new RegExp(reStr, 'g'), '-');_x000D_
_x000D_
console.log( newStr );  // "this-is-a-test"

'\0' is the way to go. It's a character, which is what's wanted in a string and has the null value.

When we say null terminated string in C/C++, it really means 'zero terminated string'. The NULL macro isn't intended for use in terminating strings.

Actually, the jQuery documentation has a more simple approach than the chained examples shown above (although they'll work just fine):

$("#myElement").unbind('mouseenter mouseleave');

As of jQuery 1.7, you are also able use $.on() and $.off() for event binding, so to unbind the hover event, you would use the simpler and tidier:

$('#myElement').off('hover');

The pseudo-event-name "hover" is used as a shorthand for "mouseenter mouseleave" but was handled differently in earlier jQuery versions; requiring you to expressly remove each of the literal event names. Using $.off() now allows you to drop both mouse events using the same shorthand.

Edit 2016:

Still a popular question so it's worth drawing attention to @Dennis98's point in the comments below that in jQuery 1.9+, the "hover" event was deprecated in favour of the standard "mouseenter mouseleave" calls. So your event binding declaration should now look like this:

$('#myElement').off('mouseenter mouseleave');

It tells the compiler that you're in a Single Thread Apartment model. This is an evil COM thing, it's usually used for Windows Forms (GUI's) as that uses Win32 for its drawing, which is implemented as STA. If you are using something that's STA model from multiple threads then you get corrupted objects.

This is why you have to invoke onto the Gui from another thread (if you've done any forms coding).

Basically don't worry about it, just accept that Windows GUI threads must be marked as STA otherwise weird stuff happens.

How about something like

git log --pretty=oneline master > 1
git log --pretty=oneline branch_A > 2

git rev-parse `diff 1 2 | tail -1 | cut -c 3-42`^

If you are going to be doing this a lot, it might be good to define a utility function that will let you use arbitrary brace substitutes instead, like

def custom_format(string, brackets, *args, **kwargs):
    if len(brackets) != 2:
        raise ValueError('Expected two brackets. Got {}.'.format(len(brackets)))
    padded = string.replace('{', '{{').replace('}', '}}')
    substituted = padded.replace(brackets[0], '{').replace(brackets[1], '}')
    formatted = substituted.format(*args, **kwargs)
    return formatted

>>> custom_format('{{[cmd]} process 1}', brackets='[]', cmd='firefox.exe')
'{{firefox.exe} process 1}'

Note that this will work either with brackets being a string of length 2 or an iterable of two strings (for multi-character delimiters).

<TextView
    android:layout_width="wrap_content"
    android:layout_height="32dp"
    android:background="@drawable/a"
    android:drawableLeft="@drawable/concern_black"
    android:gravity="center"
    android:paddingLeft="10dp"
    android:paddingRight="10dp"
    android:drawablePadding="10dp"
    android:text="text"/>

note: layout_width needs to be wrap_content and use paddingLeft paddingRight drawablePadding to control gap. If you specify layout_width value is will has gap between icon and text, I think once give the layout_width a specify value, the padding will measure.

man ssh gives me this options would could be useful.

-i identity_file Selects a file from which the identity (private key) for RSA or DSA authentication is read. The default is ~/.ssh/identity for protocol version 1, and ~/.ssh/id_rsa and ~/.ssh/id_dsa for pro- tocol version 2. Identity files may also be specified on a per- host basis in the configuration file. It is possible to have multiple -i options (and multiple identities specified in config- uration files).

So you could create an alias in your bash config with something like

alias ssh="ssh -i /path/to/private_key"

I haven't looked into a ssh configuration file, but like the -i option this too could be aliased

-F configfile Specifies an alternative per-user configuration file. If a configuration file is given on the command line, the system-wide configuration file (/etc/ssh/ssh_config) will be ignored. The default for the per-user configuration file is ~/.ssh/config.

Confirm gives you chance to click on cancel, and reload will not be done!

Instead, you can use something like this:

if(alert('Alert For your User!')){}
else    window.location.reload(); 

This will display alert to your user, and when he clicks OK, it will return false and reload will be done! :) Also, the shorter version:

if(!alert('Alert For your User!')){window.location.reload();}

I hope that this helped!? :)

Sorry, I don't know how to use LaTeX syntax on stackoverflow..

Like the previous comment mention, the message "It looks like you are trying to access MongoDB over HTTP on the native driver port." its a warning because you are missunderstanding this line: mongoose.connect('mongodb://localhost/info'); and browsing this url: http://localhost:28017/

However, if you want to see the mongo's admin web page, you could do it, with this command:

mongod --rest --httpinterface

browsing this url: http://localhost:28017/

the parameter httpinterface activate the admin web page, and the parameter rest its needed for activate the rest services the page require

This will work:

if (val) {
    alert("Not null");
} else {
    alert("Null");
}

An interesting observation I made while passing previous state params from one route to another is that $stateParams gets hoisted and overwrites the previous route's state params that were passed with the current state params, but using $state.params doesn't.

When using $stateParams:

var stateParams        = {};
stateParams.nextParams = $stateParams; //{item_id:123}
stateParams.next       = $state.current.name;

$state.go('app.login', stateParams);
//$stateParams.nextParams on app.login is now:
//{next:'app.details', nextParams:{next:'app.details'}}

When using $state.params:

var stateParams        = {};
stateParams.nextParams = $state.params; //{item_id:123}
stateParams.next       = $state.current.name;

$state.go('app.login', stateParams);
//$stateParams.nextParams on app.login is now:
//{next:'app.details', nextParams:{item_id:123}}

Put this in your CMakeLists.txt file (change any options from OFF to ON if you want):

set(Boost_USE_STATIC_LIBS OFF) 
set(Boost_USE_MULTITHREADED ON)  
set(Boost_USE_STATIC_RUNTIME OFF) 
find_package(Boost 1.45.0 COMPONENTS *boost libraries here*) 

if(Boost_FOUND)
    include_directories(${Boost_INCLUDE_DIRS}) 
    add_executable(progname file1.cxx file2.cxx) 
    target_link_libraries(progname ${Boost_LIBRARIES})
endif()

Obviously you need to put the libraries you want where I put *boost libraries here*. For example, if you're using the filesystem and regex library you'd write:

find_package(Boost 1.45.0 COMPONENTS filesystem regex)

Just came acreoss this, and since I had the same issue, I'd just post the results I came up with

when parsing, you could update the offset (ie I am parsing a data (1.1.2014) and I only want the date, 1st Jan 2014. On GMT+1 I'd get 31.12.2013. So I offset the value first.

moment(moment.utc('1.1.2014').format());

Well, came in handy for me to support across timezones

The thing about classes, and setting unencumbered global variables equal to some value within the class, is that what your global variable stores is actually the reference to the memory location the value is actually stored.

What you're seeing in your output is indicative of this.

Where you might be able to see the value and use print without issue on the initial global variables you used because of the str method and how print works, you won't be able to do this with lists, because what is stored in the elements within that list is just a reference to the memory location of the value -- read up on aliases, if you'd like to know more.

Additionally, when using lists and losing track of what is an alias and what is not, you might find you're changing the value of the original list element, if you change it in an alias list -- because again, when you set a list element equal to a list or element within a list, the new list only stores the reference to the memory location (it doesn't actually create new memory space specific to that new variable). This is where deepcopy comes in handy!

I was getting the exact same error, however I solved it by running $false first and then $true.

My issue was by putting wrong parameters in the header, the requested parameters was

Authorization: Token <string>

and is was trying

Authorization Token: <string>

Broken pipe simply means that the connection has failed. It is reasonable to assume that this is unrecoverable, and to then perform any required cleanup actions (closing connections, etc). I don't believe that you would ever see this simply due to the connection not yet being complete.

If you are using non-blocking mode then the SocketChannel.connect method will return false, and you will need to use the isConnectionPending and finishConnect methods to insure that the connection is complete. I would generally code based upon the expectation that things will work, and then catch exceptions to detect failure, rather than relying on frequent calls to "isConnected".

Well... I flipped the internet upside down three times but did not find anything that might help me because it was a Drupal project rather than other scenarios people described.

My problem was that someone in the project added a js which his address was: <script src="http://base_url/?p4sxbt"></script> and it was attached in this way:

drupal_add_js('',
    array('scope' => 'footer', 'weight' => 5)
  );

Hope this will help someone in the future.

Here is an easier way that worked for me:

const express = require('express');
var app = express();
var fs = require('fs');

app.post('/upload', async function(req, res) {

  var file = JSON.parse(JSON.stringify(req.files))

  var file_name = file.file.name

  //if you want just the buffer format you can use it
  var buffer = new Buffer.from(file.file.data.data)

  //uncomment await if you want to do stuff after the file is created

  /*await*/
  fs.writeFile(file_name, buffer, async(err) => {

    console.log("Successfully Written to File.");


    // do what you want with the file it is in (__dirname + "/" + file_name)

    console.log("end  :  " + new Date())

    console.log(result_stt + "")

    fs.unlink(__dirname + "/" + file_name, () => {})
    res.send(result_stt)
  });


});

The solution is very simple, but took me about 2 hours and half the hair on my head to find it.

Simply wrap your content with a (redundant) div that has display: none and Bob is your uncle.

<div style="display: none">
    <div id="content-div">Some content here</div>
</div>

Voila

It's a linker error. ld is the linker, so if you get an error message ending with "ld returned 1 exit status", that tells you that it's a linker error.

The error message tells you that none of the object files you're linking against contains a definition for avergecolumns. The reason for that is that the function you've defined is called averagecolumns (in other words: you misspelled the function name when calling the function (and presumably in the header file as well - otherwise you'd have gotten a different error at compile time)).

Functions dealing with text like label, title, etc. accept parameters same as matplotlib.text.Text. For the font size you can use size/fontsize:

from matplotlib import pyplot as plt    

fig = plt.figure()
plt.plot(data)
fig.suptitle('test title', fontsize=20)
plt.xlabel('xlabel', fontsize=18)
plt.ylabel('ylabel', fontsize=16)
fig.savefig('test.jpg')

For globally setting title and label sizes, mpl.rcParams contains axes.titlesize and axes.labelsize. (From the page):

axes.titlesize      : large   # fontsize of the axes title
axes.labelsize      : medium  # fontsize of the x any y labels

(As far as I can see, there is no way to set x and y label sizes separately.)

And I see that axes.titlesize does not affect suptitle. I guess, you need to set that manually.

It is also possible to use FormData(). But you need to set contentType as false:

var data = new FormData();
data.append('name', 'Bob'); 

function sendData() {
    $.ajax({
        url: '/helloworld',
        type: 'POST',
        contentType: false,
        data: data,
        dataType: 'json'
    });
}

Use your bean class like this, if your JSON data starts with an an array object. it helps you.

Users[] bean = gson.fromJson(response,Users[].class);

Users is my bean class.

Response is my JSON data.

I got much better solution .

here is my directive , I have injected on object reference in directive and has extend that by adding invoke function in directive code .

app.directive('myDirective', function () {
    return {
        restrict: 'E',
        scope: {
        /*The object that passed from the cntroller*/
        objectToInject: '=',
        },
        templateUrl: 'templates/myTemplate.html',

        link: function ($scope, element, attrs) {
            /*This method will be called whet the 'objectToInject' value is changes*/
            $scope.$watch('objectToInject', function (value) {
                /*Checking if the given value is not undefined*/
                if(value){
                $scope.Obj = value;
                    /*Injecting the Method*/
                    $scope.Obj.invoke = function(){
                        //Do something
                    }
                }    
            });
        }
    };
});

Declaring the directive in the HTML with a parameter:

<my-directive object-to-inject="injectedObject"></ my-directive>

my Controller:

app.controller("myController", ['$scope', function ($scope) {
   // object must be empty initialize,so it can be appended
    $scope.injectedObject = {};

    // now i can directly calling invoke function from here 
     $scope.injectedObject.invoke();
}];

Changing 'Installed JREs' under 'Preferences -> Java -> Installed JRE' to JDK home worked for me.

FYI - Am using JDK 1.8.

element.GetAttribute("value");

Eventhough if you don't see the "value" attribute in html dom, you will get the field value displayed on the GUI.

Use "This is' it".replace("'", "\\'")

You can also use the sqldf package which performs selects on R data frames as :

df1 <- sqldf("select A, B, E from df")

This gives as the output a data frame df1 with columns: A, B ,E.

You may debug by firefox also.

Follow these steps: Tool->Attach to process and select firefox.exe or your default browser. Then debugger will work with this browser. But I had some trouble when firefox is 32 bit and and VS2010 is 64 bit.

Anyway right click the current document, browse with --> than choose your browser, than set it as default. This way is better. B'cause firefox's process id may change, so you will be annoyed for attaching the process again.

As for me I decided to use paddings. It is not exactly what you need, but may be useful in some cases.

table td {
    padding: 15px 0;
}

In vi(m), check out:

:help 'list'
:help 'listchars' 

I guess you will get ORA-01741: illegal zero-length identifier if you use the following

SELECT "" AS Contact  FROM Customers;

And if you use the following 2 statements, you will be getting the same null value populated in the column.

SELECT '' AS Contact FROM Customers; OR SELECT null AS Contact FROM Customers;

db.<collectionName>.find({"IMAGE URL":{"$exists":"true"}, "IMAGE URL": {$ne: null}})

You can disable the Rollback:

@TransactionConfiguration(defaultRollback = false)

Example:

@RunWith(SpringJUnit4ClassRunner.class)
@SpringApplicationConfiguration(classes = Application.class)
@Transactional
@TransactionConfiguration(defaultRollback = false)
public class Test {
    @PersistenceContext
    private EntityManager em;

    @org.junit.Test
    public void menge() {
        PersistentObject object = new PersistentObject();
        em.persist(object);
        em.flush();
    }
}

In my case , I edited my files on Linux where I had node v14.0.5 installed, when I rebooted to Windows where I had node v14.0.3 I got the same error. So I updated the node version on windows and all went fine for me.

Git has two types of branches: local and remote. To use git pull and git push as you'd like, you have to tell your local branch (my_test) which remote branch it's tracking. In typical Git fashion this can be done in both the config file and with commands.

Commands

Make sure you're on your master branch with

1)git checkout master

then create the new branch with

2)git branch --track my_test origin/my_test

and check it out with

3)git checkout my_test.

You can then push and pull without specifying which local and remote.

However if you've already created the branch then you can use the -u switch to tell git's push and pull you'd like to use the specified local and remote branches from now on, like so:

git pull -u my_test origin/my_test
git push -u my_test origin/my_test

Config

The commands to setup remote branch tracking are fairly straight forward but I'm listing the config way as well as I find it easier if I'm setting up a bunch of tracking branches. Using your favourite editor open up your project's .git/config and add the following to the bottom.

[remote "origin"]
    url = [email protected]:username/repo.git
    fetch = +refs/heads/*:refs/remotes/origin/*
[branch "my_test"]
    remote = origin
    merge = refs/heads/my_test

This specifies a remote called origin, in this case a GitHub style one, and then tells the branch my_test to use it as it's remote.

You can find something very similar to this in the config after running the commands above.

Some useful resources:

• http://www.kernel.org/pub/software/scm/git/docs/git-branch.html
• http://gitready.com/beginner/2009/03/09/remote-tracking-branches.html

Try installing the 32 bit version of Java 6. This works for version Install4J 4.0.5. Should fire right up, or allow you to re-run the installer.

Any newer version or the 64-bit version of 6 will fail, complaining that the java.exe is damaged.

You can display any gif image via library Fresco by Facebook:

Uri uri = Uri.parse("http://domain.com/awersome.gif");
final SimpleDraweeView draweeView = new SimpleDraweeView(context);
final LinearLayout.LayoutParams params = new LinearLayout.LayoutParams(200, 200);

draweeView.setLayoutParams(params);
DraweeController controller = Fresco.newDraweeControllerBuilder()
        .setUri(uri)
        .setAutoPlayAnimations(true)
        .build();
draweeView.setController(controller);
//now just add draweeView to layout and enjoy

Here's a method which is similar to Kelly's but will remove any pre-existing script with the same source, and uses jQuery.

<script>
    function reload_js(src) {
        $('script[src="' + src + '"]').remove();
        $('<script>').attr('src', src).appendTo('head');
    }
    reload_js('source_file.js');
</script>

Note that the 'type' attribute is no longer needed for scripts as of HTML5. (http://www.w3.org/html/wg/drafts/html/master/scripting-1.html#the-script-element)

This would do it.

     public static void main(String[] args) {
        double d = 12.349678;
        int r = (int) Math.round(d*100);
        double f = r / 100.0;
       System.out.println(f);
     }

You can short this method, it's easy to understand that's why I have written like this.

I know this is an old question, but it hasn't been correctly addressed, so I'm answering it for others who may run into this problem.

By default Oracle's ODP.net binds variables by position, and treats each position as a new variable.

Treating each copy as a different variable and setting it's value multiple times is a workaround and a pain, as furman87 mentioned, and could lead to bugs, if you are trying to rewrite the query and move things around.

The correct way is to set the BindByName property of OracleCommand to true as below:

var cmd = new OracleCommand(cmdtxt, conn);
cmd.BindByName = true;

You could also create a new class to encapsulate OracleCommand setting the BindByName to true on instantiation, so you don't have to set the value each time. This is discussed in this post

You can use -

Ternary oprator to check wheather value set by POST/GET or not somthing like this

$value1 = $_POST['value1'] = isset($_POST['value1']) ? $_POST['value1'] : '';
$value2 = $_POST['value2'] = isset($_POST['value2']) ? $_POST['value2'] : '';
$value3 = $_POST['value3'] = isset($_POST['value3']) ? $_POST['value3'] : '';
$value4 = $_POST['value4'] = isset($_POST['value4']) ? $_POST['value4'] : '';

Updated to use git push --mirror origin instead of git push -f origin as suggested in the comments.

This worked for me flawlessly.

git clone --mirror <URL to my OLD repo location>
cd <New directory where your OLD repo was cloned>
git remote set-url origin <URL to my NEW repo location>
git push --mirror origin

I have to mention though that this creates a mirror of your current repo and then pushes that to the new location. Therefore, this can take some time for large repos or slow connections.

The e.offsetWidth < e.scrollWidth solution is not always working.

And if you want to use pure JavaScript, I recommend to use this:

(typescript)

public isEllipsisActive(element: HTMLElement): boolean {
    element.style.overflow = 'initial';
    const noEllipsisWidth = element.offsetWidth;
    element.style.overflow = 'hidden';
    const ellipsisWidth = element.offsetWidth;

    if (ellipsisWidth < noEllipsisWidth) {
      return true;
    } else {
      return false;
    }
}

Great question, because many developers, even experienced ones, are confused by the way PHP handles arrays in foreach loops. In the standard foreach loop, PHP makes a copy of the array that is used in the loop. The copy is discarded immediately after the loop finishes. This is transparent in the operation of a simple foreach loop. For example:

$set = array("apple", "banana", "coconut");
foreach ( $set AS $item ) {
    echo "{$item}\n";
}

This outputs:

apple
banana
coconut

So the copy is created but the developer doesn't notice, because the original array isn’t referenced within the loop or after the loop finishes. However, when you attempt to modify the items in a loop, you find that they are unmodified when you finish:

$set = array("apple", "banana", "coconut");
foreach ( $set AS $item ) {
    $item = strrev ($item);
}

print_r($set);

This outputs:

Array
(
    [0] => apple
    [1] => banana
    [2] => coconut
)

Any changes from the original can't be notices, actually there are no changes from the original, even though you clearly assigned a value to $item. This is because you are operating on $item as it appears in the copy of $set being worked on. You can override this by grabbing $item by reference, like so:

$set = array("apple", "banana", "coconut");
foreach ( $set AS &$item ) {
    $item = strrev($item);
}
print_r($set);

This outputs:

Array
(
    [0] => elppa
    [1] => ananab
    [2] => tunococ
)

So it is evident and observable, when $item is operated on by-reference, the changes made to $item are made to the members of the original $set. Using $item by reference also prevents PHP from creating the array copy. To test this, first we’ll show a quick script demonstrating the copy:

$set = array("apple", "banana", "coconut");
foreach ( $set AS $item ) {
    $set[] = ucfirst($item);
}
print_r($set);

This outputs:

Array
(
    [0] => apple
    [1] => banana
    [2] => coconut
    [3] => Apple
    [4] => Banana
    [5] => Coconut
)

As it is shown in the example, PHP copied $set and used it to loop over, but when $set was used inside the loop, PHP added the variables to the original array, not the copied array. Basically, PHP is only using the copied array for the execution of the loop and the assignment of $item. Because of this, the loop above only executes 3 times, and each time it appends another value to the end of the original $set, leaving the original $set with 6 elements, but never entering an infinite loop.

However, what if we had used $item by reference, as I mentioned before? A single character added to the above test:

$set = array("apple", "banana", "coconut");
foreach ( $set AS &$item ) {
    $set[] = ucfirst($item);
}
print_r($set);

Results in an infinite loop. Note this actually is an infinite loop, you’ll have to either kill the script yourself or wait for your OS to run out of memory. I added the following line to my script so PHP would run out of memory very quickly, I suggest you do the same if you’re going to be running these infinite loop tests:

ini_set("memory_limit","1M");

So in this previous example with the infinite loop, we see the reason why PHP was written to create a copy of the array to loop over. When a copy is created and used only by the structure of the loop construct itself, the array stays static throughout the execution of the loop, so you’ll never run into issues.

If you want an explicit check against false (and not undefined, null and others which I assume as you are using !== instead of !=) then yes, you have to use that.

Also, this is the same in a slightly smaller footprint:

if(borrar() !== !1)

What I know is one reason when “GC overhead limit exceeded” error is thrown when 2% of the memory is freed after several GC cycles

By this error your JVM is signalling that your application is spending too much time in garbage collection. so the little amount GC was able to clean will be quickly filled again thus forcing GC to restart the cleaning process again.

You should try changing the value of -Xmx and -Xms.

the problem can because of MVC MW.you must set formatterType in MVC options:

services.AddMvc(options =>
            {
                options.UseCustomStringModelBinder();
                options.AllowEmptyInputInBodyModelBinding = true;
                foreach (var formatter in options.InputFormatters)
                {
                    if (formatter.GetType() == typeof(SystemTextJsonInputFormatter))
                        ((SystemTextJsonInputFormatter)formatter).SupportedMediaTypes.Add(
                            Microsoft.Net.Http.Headers.MediaTypeHeaderValue.Parse("text/plain"));
                }
            }).AddJsonOptions(options =>
            {
                options.JsonSerializerOptions.PropertyNameCaseInsensitive = true;
            });

Evidently, sometimes, the display properties of parent of the element containing the matter that shouldn't overflow should also be set to overflow:hidden as well, e.g.:

<div style="overflow: hidden">
  <div style="overflow: hidden">some text that should not overflow<div>
</div>

Why? I have no idea but it worked for me. See https://medium.com/@crrollyson/overflow-hidden-not-working-check-the-child-element-c33ac0c4f565 (ignore the sniping at stackoverflow!)

How about this? I needed the exact same thing, I had to create one from scratch. It's PURE CSS, and works in IE9+ Feel-free to improve upon it.

Demo: http://www.d-k-j.com/Articles/Web_Development/Pure_CSS_5_Star_Rating_System_with_Radios/

<ul class="form">
    <li class="rating">
        <input type="radio" name="rating" value="0" checked /><span class="hide"></span>
        <input type="radio" name="rating" value="1" /><span></span>
        <input type="radio" name="rating" value="2" /><span></span>
        <input type="radio" name="rating" value="3" /><span></span>
        <input type="radio" name="rating" value="4" /><span></span>
        <input type="radio" name="rating" value="5" /><span></span>
    </li>
</ul>

CSS:

.form {
    margin:0;
}

.form li {
    list-style:none;
}

.hide {
    display:none;
}

.rating input[type="radio"] {
    position:absolute;
    filter:alpha(opacity=0);
    -moz-opacity:0;
    -khtml-opacity:0;
    opacity:0;
    cursor:pointer;
    width:17px;
}

.rating span {
    width:24px;
    height:16px;
    line-height:16px;
    padding:1px 22px 1px 0; /* 1px FireFox fix */
    background:url(stars.png) no-repeat -22px 0;
}

.rating input[type="radio"]:checked + span {
    background-position:-22px 0;
}

.rating input[type="radio"]:checked + span ~ span {
    background-position:0 0;
}

Yes you can do by using jQuery as:

<script>
$(document).ready(function()
{
    $("#username").blur(function()
    {
        //remove all the class add the messagebox classes and start fading
        $("#msgbox").removeClass().addClass('messagebox').text('Checking...').fadeIn("slow");
        //check the username exists or not from ajax
        $.post("user_availability.php",{ user_name:$(this).val() } ,function(data)
        {
          if(data=='empty') // if username is empty
          {
            $("#msgbox").fadeTo(200,0.1,function() //start fading the messagebox
            { 
              //add message and change the class of the box and start fading
              $(this).html('Empty user id is not allowed').addClass('messageboxerror').fadeTo(900,1);
            });
          }
          else if(data=='invalid') // if special characters used in username
          {
            $("#msgbox").fadeTo(200,0.1,function() //start fading the messagebox
            { 
              //add message and change the class of the box and start fading
              $(this).html('Sorry, only letters (a-z), numbers (0-9), and periods (.) are allowed.').addClass('messageboxerror').fadeTo(900,1);
            });
          }
          else if(data=='no') // if username not avaiable
          {
            $("#msgbox").fadeTo(200,0.1,function() //start fading the messagebox
            { 
              //add message and change the class of the box and start fading
              $(this).html('User id already exists').addClass('messageboxerror').fadeTo(900,1);
            });     
          }
          else
          {
            $("#msgbox").fadeTo(200,0.1,function()  //start fading the messagebox
            { 
              //add message and change the class of the box and start fading
              $(this).html('User id available to register').addClass('messageboxok').fadeTo(900,1); 
            });
          }

        });

    });
});
</script>
<input type="text" id="username" name="username"/><span id="msgbox" style="display:none"></span>

and script for your user_availability.php will be:

<?php
include'includes/config.php';

//value got from the get method
$user_name = trim($_POST['user_name']);

if($user_name == ''){
    echo "empty";
}elseif(preg_match('/[\'^£$%&*()}{@#~?><>,|=_+¬-]/', $user_name)){
    echo "invalid";
}else{
    $select = mysql_query("SELECT user_id FROM staff");

    $i=0;
    //this varible contains the array of existing users
    while($fetch = mysql_fetch_array($select)){
        $existing_users[$i] = $fetch['user_id'];
        $i++;
    }

    //checking weather user exists or not in $existing_users array
    if (in_array($user_name, $existing_users))
    {
        //user name is not availble
        echo "no";
    } 
    else
    {
        //user name is available
        echo "yes";
    }
}
?>

I tried to add for / and \ but not succeeded.

You can also do it by using javascript & code will be:

<!-- Check special characters in username start -->
<script language="javascript" type="text/javascript">
function check(e) {
    var keynum
    var keychar
    var numcheck
    // For Internet Explorer
    if (window.event) {
        keynum = e.keyCode;
    }
    // For Netscape/Firefox/Opera
    else if (e.which) {
        keynum = e.which;
    }
    keychar = String.fromCharCode(keynum);
    //List of special characters you want to restrict
    if (keychar == "'" || keychar == "`" || keychar =="!" || keychar =="@" || keychar =="#" || keychar =="$" || keychar =="%" || keychar =="^" || keychar =="&" || keychar =="*" || keychar =="(" || keychar ==")" || keychar =="-" || keychar =="_" || keychar =="+" || keychar =="=" || keychar =="/" || keychar =="~" || keychar =="<" || keychar ==">" || keychar =="," || keychar ==";" || keychar ==":" || keychar =="|" || keychar =="?" || keychar =="{" || keychar =="}" || keychar =="[" || keychar =="]" || keychar =="¬" || keychar =="£" || keychar =='"' || keychar =="\\") {
        return false;
    } else {
        return true;
    }
}
</script>
<!-- Check special characters in username end -->

<!-- in your form -->
    User id : <input type="text" id="txtname" name="txtname" onkeypress="return check(event)"/>

types is optional

Some times it just happens due to installation of Wamp or changing of password options of root user. One can use privilages-->root (user) and then set password option to NO to run the things without any password OR set the password and use it in the application.

If using Visual Code one option is to add this to the settings.json file:

"eslint.options": {
    "useEslintrc": false,
    "parserOptions": {
        "ecmaVersion": 2017
    },
    "env": {
        "es6": true
    }
}

var string  = "Hello World";
console.log(charAt(0));

The charAt(0) is JavaScript method, It will return value based on index, here 0 is the index for first letter.

We have a similar situation at work, where the production machines have no access to the Internet; therefore everything has to be managed offline and off-host.

Here is what I tried with varied amounts of success:

1. basket which is a small utility that you run on your internet-connected host. Instead of trying to install a package, it will instead download it, and everything else it requires to be installed into a directory. You then move this directory onto your target machine. Pros: very easy and simple to use, no server headaches; no ports to configure. Cons: there aren't any real showstoppers, but the biggest one is that it doesn't respect any version pinning you may have; it will always download the latest version of a package.

2. Run a local pypi server. Used pypiserver and devpi. pypiserver is super simple to install and setup; devpi takes a bit more finagling. They both do the same thing - act as a proxy/cache for the real pypi and as a local pypi server for any home-grown packages. localshop is a new one that wasn't around when I was looking, it also has the same idea. So how it works is your internet-restricted machine will connect to these servers, they are then connected to the Internet so that they can cache and proxy the actual repository.

The problem with the second approach is that although you get maximum compatibility and access to the entire repository of Python packages, you still need to make sure any/all dependencies are installed on your target machines (for example, any headers for database drivers and a build toolchain). Further, these solutions do not cater for non-pypi repositories (for example, packages that are hosted on github).

We got very far with the second option though, so I would definitely recommend it.

Eventually, getting tired of having to deal with compatibility issues and libraries, we migrated the entire circus of servers to commercially supported docker containers.

This means that we ship everything pre-configured, nothing actually needs to be installed on the production machines and it has been the most headache-free solution for us.

We replaced the pypi repositories with a local docker image server.

The following page provides a relatively good guide that requires few corrections : https://cv-tricks.com/how-to/installation-of-opencv-4-1-0-in-windows-10-from-source/

On step 8, when you are choosing generator for the project (tool used for building), don't forget to specify x64 in the second field if you need it. If you don't, you will get LNK1112 error, which is a linker error caused if one module is created with the x64 compiler, and another module is created with the x86 compiler.

Next, when choosing flags in step 9, don't forget to tick the "OPENCV_ENABLE_NONFREE", and set the path for flag "OPENCV_EXTRA_MODULES_PATH" flag. The path must be set to "modules" folder in opencv-contrib-python.

So you need both opencv, and opencv-contrib-python in order to use SIFT and SURF.

very old question, i know. but with the new f-strings (starting from python 3.6) there are fresh options. so here for completeness:

from datetime import datetime

dt = datetime.now()

# str.format
strg = '{:%B %d, %Y}'.format(dt)
print(strg)  # July 22, 2017

# datetime.strftime
strg = dt.strftime('%B %d, %Y')
print(strg)  # July 22, 2017

# f-strings in python >= 3.6
strg = f'{dt:%B %d, %Y}'
print(strg)  # July 22, 2017

strftime() and strptime() Behavior explains what the format specifiers mean.

You may have this issue as well if you have environment variable GCC_ROOT pointing to a wrong location. Probably simplest fix could be (on *nix like system):

unset GCC_ROOT

in more complicated cases you may need to repoint it to proper location

                android:bottom="5dp"
                android:left="5dp"
                android:right="5dp"
                android:top="5dp" />
        </shape>
    </item>
</layer-list>

Then simply set the android:background attribute to dotted.xml we just created. Your EditText looks like this.

<EditText
    android:id="@+id/editText"
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:text="Some Text"
    android:background="@drawable/dotted" />

Use another flex container to fix the min-height issue in IE10 and IE11:

HTML

<div class="ie-fixMinHeight">
    <div id="page">
        <div id="header"></div>
        <div id="content"></div>
        <div id="footer"></div>
    </div>
</div>

CSS

.ie-fixMinHeight {
    display:flex;
}

#page {
    min-height:100vh;
    width:100%;
    display:flex;
    flex-direction:column;
}

#content {
    flex-grow:1;
}

See a working demo.

• Don't use flexbox layout directly on body because it screws up elements inserted via jQuery plugins (autocomplete, popup, etc.).
• Don't use height:100% or height:100vh on your container because the footer will stick at the bottom of window and won't adapt to long content.
• Use flex-grow:1 rather than flex:1 cause IE10 and IE11 default values for flex are 0 0 auto and not 0 1 auto.

I got this to work:

>>> import locale
>>> locale.setlocale(locale.LC_ALL, 'en_US')
'en_US'
>>> locale.format("%d", 1255000, grouping=True)
'1,255,000'

Sure, you don't need internationalization support, but it's clear, concise, and uses a built-in library.

P.S. That "%d" is the usual %-style formatter. You can have only one formatter, but it can be whatever you need in terms of field width and precision settings.

P.P.S. If you can't get locale to work, I'd suggest a modified version of Mark's answer:

def intWithCommas(x):
    if type(x) not in [type(0), type(0L)]:
        raise TypeError("Parameter must be an integer.")
    if x < 0:
        return '-' + intWithCommas(-x)
    result = ''
    while x >= 1000:
        x, r = divmod(x, 1000)
        result = ",%03d%s" % (r, result)
    return "%d%s" % (x, result)

Recursion is useful for the negative case, but one recursion per comma seems a bit excessive to me.

If you can use java streams, you can try the following:

Random randomizeTimestamp = new Random();
Long min = ZonedDateTime.parse("2018-01-01T00:00:00.000Z").toInstant().toEpochMilli();
Long max = ZonedDateTime.parse("2019-01-01T00:00:00.000Z").toInstant().toEpochMilli();
randomizeTimestamp.longs(generatedEventListSize, min, max).forEach(timestamp -> {
  System.out.println(timestamp);
});

This will generate numbers in the given range for longs.

str() is the equivalent.

However you should be filtering your query. At the moment your query is all() Todo's.

todos = Todo.all().filter('author = ', users.get_current_user().nickname()) 

or

todos = Todo.all().filter('author = ', users.get_current_user())

depending on what you are defining author as in the Todo model. A StringProperty or UserProperty.

Note nickname is a method. You are passing the method and not the result in template values.

    println "[ERROR] ${proc.getErrorStream()}"
  }
  assert !proc.exitValue()
}

adb shell
am start -n com.package.name/com.package.name.ActivityName

Or you can use this directly:

adb shell am start -n com.package.name/com.package.name.ActivityName

You can also specify actions to be filter by your intent-filters:

am start -a com.example.ACTION_NAME -n com.package.name/com.package.name.ActivityName 

Using def change means you should write migrations that are reversible. And change_column is not reversible. You can go up but you cannot go down, since change_column is irreversible.

Instead, though it may be a couple extra lines, you should use def up and def down

So if you have a column with no default value, then you should do this to add a default value.

def up
  change_column :users, :admin, :boolean, default: false
end

def down
  change_column :users, :admin, :boolean, default: nil
end

Or if you want to change the default value for an existing column.

def up
  change_column :users, :admin, :boolean, default: false
end

def down
  change_column :users, :admin, :boolean, default: true
end

I think you are putting one too many curly brackets. Try this

 @if($user->status=='waiting')
            <td><a href="#" class="viewPopLink btn btn-default1" role="button" data-id="{!! $user->travel_id !!}" data-toggle="modal" data-target="#myModal">Approve/Reject</a> </td>
            @else
            <td>{!! $user->status !!}</td>
        @endif

// This code works for images on 2.2, not sure if any other media types

   //Your file path - Example here is "/sdcard/cats.jpg"
   final String filePathThis = imagePaths.get(position).toString();

   MediaScannerConnectionClient mediaScannerClient = new
   MediaScannerConnectionClient() {
    private MediaScannerConnection msc = null;
    {
        msc = new MediaScannerConnection(getApplicationContext(), this);
        msc.connect();
    }

    public void onMediaScannerConnected(){
        msc.scanFile(filePathThis, null);
    }


    public void onScanCompleted(String path, Uri uri) {
        //This is where you get your content uri
            Log.d(TAG, uri.toString());
        msc.disconnect();
    }
   };

you cannot call a controller method from another controller directly

my solution is to use inheritances and extend your controller from the library controller

class Controller1 extends CI_Controller {

    public function index() {
        // some codes here
    }

    public function methodA(){
        // code here
    }
}

in your controller we call it Mycontoller it will extends Controller1

include_once (dirname(__FILE__) . "/controller1.php");

class Mycontroller extends Controller1 {

    public function __construct() {
        parent::__construct();
    }

    public function methodB(){
        // codes....
    }
}

and you can call methodA from mycontroller

http://example.com/mycontroller/methodA

http://example.com/mycontroller/methodB

this solution worked for me

var element = $("#parentDiv .myClassNameOfInterest")

In my case, this happens when I try to save an object in hibernate or other orm-mapping with null property which can not be null in database table. This happens when you try to save an object, but the save action doesn't comply with the contraints of the table.

This errors says your function is already defined ; which can mean :

• you have the same function defined in two files
• or you have the same function defined in two places in the same file
• or the file in which your function is defined is included two times (so, it seems the function is defined two times)

I think your facing problem at 3rd position the script including this file more than one time.So, you can solve it by using require_once instead of require or include_once instead of include for including your functions.php file -- so it cannot be included more than once.

If you are working with HTTP APIs specifically, there are also more convenient choices such as Nap.

For example, here's how to get gists from Github since May 1st 2014:

from nap.url import Url
api = Url('https://api.github.com')

gists = api.join('gists')
response = gists.get(params={'since': '2014-05-01T00:00:00Z'})
print(response.json())

More examples: https://github.com/kimmobrunfeldt/nap#examples

Also try aspnet_regiis -u then aspnet_regiis -i on below path

C:\Windows\Microsoft.NET\Framework\v4.0.30319 

Now restart the IIS and check

Hope this will help !

Not a full answer but perhaps a useful hint. If it is really the first item you want*, then

next(iter(q))

is much faster than

list(q)[0]

for large dicts, since the whole thing doesn't have to be stored in memory.

For 10.000.000 items I found it to be almost 40.000 times faster.

*The first item in case of a dict being just a pseudo-random item before Python 3.6 (after that it's ordered in the standard implementation, although it's not advised to rely on it).

You can do this:

add-pssnapin Microsoft.Exchange.Management.PowerShell.E2010

and most of it will work (although MS support will tell you that doing this is not supported because it bypasses RBAC).

I've seen issues with some cmdlets (specifically enable/disable UMmailbox) not working with just the snapin loaded.

In Exchange 2010, they basically don't support using Powershell outside of the the implicit remoting environment of an actual EMS shell.

    HttpClient client = new DefaultHttpClient();

    Uri.Builder builder = Uri.parse(url).buildUpon();

    for (String name : params.keySet()) {
        builder.appendQueryParameter(name, params.get(name).toString());
    }

    url = builder.build().toString();
    HttpGet request = new HttpGet(url);
    HttpResponse response = client.execute(request);
    return EntityUtils.toString(response.getEntity(), "UTF-8");

If you're using MySQL Workbench, right-click a table and select alter table.

In that window you can see your table Engine and also change it.

Use Mockito's doThrow and then catch the desired exception to assert it was thrown later.

@Test
public void fooShouldThrowMyException() {
    // given
    val myClass = new MyClass();
    val arg = mock(MyArgument.class);
    doThrow(MyException.class).when(arg).argMethod(any());
    Exception exception = null;

    // when
    try {
        myClass.foo(arg);
    } catch (MyException t) {
        exception = t;
    }

    // then
    assertNotNull(exception);
}

As others have stated, the String type in .NET is immutable and it's reference is passed by value.

In the original code, as soon as this line executes:

test = "after passing";

then test is no longer referring to the original object. We've created a new String object and assigned test to reference that object on the managed heap.

I feel that many people get tripped up here since there's no visible formal constructor to remind them. In this case, it's happening behind the scenes since the String type has language support in how it is constructed.

Hence, this is why the change to test is not visible outside the scope of the TestI(string) method - we've passed the reference by value and now that value has changed! But if the String reference were passed by reference, then when the reference changed we will see it outside the scope of the TestI(string) method.

Either the ref or out keyword are needed in this case. I feel the out keyword might be slightly better suited for this particular situation.

class Program
{
    static void Main(string[] args)
    {
        string test = "before passing";
        Console.WriteLine(test);
        TestI(out test);
        Console.WriteLine(test);
        Console.ReadLine();
    }

    public static void TestI(out string test)
    {
        test = "after passing";
    }
}

I'm posting this solution which applies specifically for Android Studio users. I also recently discovered Timber and have imported it successfully into my app by doing the following:

Put the latest version of the library into your build.gradle:

compile 'com.jakewharton.timber:timber:4.1.1'

Then in Android Studios, go to Edit -> Find -> Replace in Path...

Type in Log.e(TAG, or however you have defined your Log messages into the "Text to find" textbox. Then you just replace it with Timber.e(

Click Find and then replace all.

Android Studios will now go through all your files in your project and replace all the Logs with Timbers.

The only problem I had with this method is that gradle does come up witha million error messages afterwards because it cannot find "Timber" in the imports for each of your java files. Just click on the errors and Android Studios will automatically import "Timber" into your java. Once you have done it for all your errors files, gradle will compile again.

You also need to put this piece of code in your onCreate method of your Application class:

    if (BuildConfig.DEBUG) {
        Timber.plant(new Timber.DebugTree());
    }

This will result in the app logging only when you are in development mode not in production. You can also have BuildConfig.RELEASE for logging in release mode.

 if(navigator.onLine){
  alert('online');
 } else {
  alert('offline');
 }

jQuery.post() will work if you have custom data. If you want to post existing form, it's easier to use ajaxSubmit().

And you don't have to setup this code in the ActionLink itself, since you can attach link handler in the document.ready() event (which is a preferred method anyway), for example using $(function(){ ... }) jQuery trick.

Use the built-in isinstance() function.

import pandas as pd

def f(var):
    if isinstance(var, pd.DataFrame):
        print("do stuff")

it's number_map[int(x)], you tried to actually call the map with one argument

There is doing XML reading right, or doing the dodgy just to get by. Doing it right would be using proper document parsing.

Or... dodgy would be using custom text parsing with either wisuzu's response or using regular expressions with matchers.

Try this,

 $('.nav-list li').click(function() {

    $('.nav-list li.active').removeClass('active');
    $(this).addClass('active');
});

In your context $(this) will points to the UL element not the Li. Hence you are not getting the expected results.

Setting the CurrentCell and then calling BeginEdit(true) works well for me.

The following code shows an eventHandler for the KeyDown event that sets a cell to be editable.

My example only implements one of the required key press overrides but in theory the others should work the same. (and I'm always setting the [0][0] cell to be editable but any other cell should work)

    private void dataGridView1_KeyDown(object sender, KeyEventArgs e)
    {
        if (e.KeyCode == Keys.Tab && dataGridView1.CurrentCell.ColumnIndex == 1)
        {
            e.Handled = true;
            DataGridViewCell cell = dataGridView1.Rows[0].Cells[0];
            dataGridView1.CurrentCell = cell;
            dataGridView1.BeginEdit(true);               
        }
    }

If you haven't found it previously, the DataGridView FAQ is a great resource, written by the program manager for the DataGridView control, which covers most of what you could want to do with the control.

<div id='element_123_wrapper_text'>My sample DIV</div>

The Operator ^ - Match elements that starts with given value

div[id^="element_123"] {

}

The Operator $ - Match elements that ends with given value

div[id$="wrapper_text"] {

}

The Operator * - Match elements that have an attribute containing a given value

div[id*="wrapper_text"] {

}

Assuming you want no password prompt:

ssh $HOST 'echo $PASSWORD | sudo -S $COMMMAND'

Example

ssh me@localhost 'echo secret | sudo -S echo hi' # outputs 'hi'

You can do npm list | grep typescript if it's installed through npm.

From JPA 2.1 you can use AttributeConverter.

Create an enumerated class like so:

public enum NodeType {

    ROOT("root-node"),
    BRANCH("branch-node"),
    LEAF("leaf-node");

    private final String code;

    private NodeType(String code) {
        this.code = code;
    }

    public String getCode() {
        return code;
    }
}

And create a converter like this:

import javax.persistence.AttributeConverter;
import javax.persistence.Converter;

@Converter(autoApply = true)
public class NodeTypeConverter implements AttributeConverter<NodeType, String> {

    @Override
    public String convertToDatabaseColumn(NodeType nodeType) {
        return nodeType.getCode();
    }

    @Override
    public NodeType convertToEntityAttribute(String dbData) {
        for (NodeType nodeType : NodeType.values()) {
            if (nodeType.getCode().equals(dbData)) {
                return nodeType;
            }
        }

        throw new IllegalArgumentException("Unknown database value:" + dbData);
    }
}

On the entity you just need:

@Column(name = "node_type_code")

You luck with @Converter(autoApply = true) may vary by container but tested to work on Wildfly 8.1.0. If it doesn't work you can add @Convert(converter = NodeTypeConverter.class) on the entity class column.

If you are converting DataFrame to JSON, NaN will give error so best solution is in this use case is to replace NaN with None.
Here is how:

df1 = df.where((pd.notnull(df)), None)

$testArray = [
[
  "name"   => "Dinesh Madusanka",
  "gender" => "male"
],
[
  "name"   => "Tharaka Devinda",
  "gender" => "male"
],
[
  "name"   => "Dumidu Ranasinghearachchi",
  "gender" => "male"
]


 ];

  print_r($testArray);

  echo "<pre>";
  print_r($testArray);

For 2019 ...

jQuery 3.4.0 is deprecating :first, :last, :eq, :even, :odd, :lt, :gt, and :nth. When we remove Sizzle, we’ll replace it with a small wrapper around querySelectorAll, and it would be almost impossible to reimplement these selectors without a larger selector engine.

We think this trade-off is worth it. Keep in mind we will still support the positional methods, such as .first, .last, and .eq. Anything you can do with positional selectors, you can do with positional methods instead. They perform better anyway.

https://blog.jquery.com/2019/04/10/jquery-3-4-0-released/

So you should be now be using .first(), .last() instead (or no jQuery).

I faced a similar problem , here's the solution.

Step 1 : Double click on the server listed in Eclipse. Here It will display Server Configuration.

Step 2 : Just change the port Number like from 8080 to 8085.

Step 3 : Save the changes.

Step 4 : re-start your server.

The server will start .Hope it'll help you.

Update the create action as below:

def create
  ...
  respond_to do |format|
    if @reservation.save
      format.html do
        redirect_to '/'
      end
      format.json { render json: @reservation.to_json }
    else
      format.html { render 'new'} ## Specify the format in which you are rendering "new" page
      format.json { render json: @reservation.errors } ## You might want to specify a json format as well
    end
  end
end

You are using respond_to method but anot specifying the format in which a new page is rendered. Hence, the error ActionController::UnknownFormat .

DOM is a logical model that can be implemented in any convenient manner.It is based on an object structure that closely resembles the structure of the documents it models.

exec bash is a great way to re-execute and launch a new shell to replace current. just to add to the answer, $SHELL returns the current shell which is bash. By using the following, it will reload the current shell, and not only to bash.

exec $SHELL -l;

You have at least two issues in your code:

• ng-change="getScoreData(Score)

  Angular doesn't see getScoreData method that refers to defined service

• getScoreData: function (Score, callback)

  We don't need to use callback since GET returns promise. Use then instead.

Here is a working example (I used random address only for simulation):

HTML

<select ng-model="score"
        ng-change="getScoreData(score)" 
        ng-options="score as score.name for score in  scores"></select>
    <pre>{{ScoreData|json}}</pre> 

JS

var fessmodule = angular.module('myModule', ['ngResource']);

fessmodule.controller('fessCntrl', function($scope, ScoreDataService) {

    $scope.scores = [{
        name: 'Bukit Batok Street 1',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, 153 Bukit Batok Street 1&sensor=true'
    }, {
        name: 'London 8',
        URL: 'http://maps.googleapis.com/maps/api/geocode/json?address=Singapore, SG, Singapore, London 8&sensor=true'
    }];

    $scope.getScoreData = function(score) {
        ScoreDataService.getScoreData(score).then(function(result) {
            $scope.ScoreData = result;
        }, function(result) {
            alert("Error: No data returned");
        });
    };

});

fessmodule.$inject = ['$scope', 'ScoreDataService'];

fessmodule.factory('ScoreDataService', ['$http', '$q', function($http) {

    var factory = {
        getScoreData: function(score) {
            console.log(score);
            var data = $http({
                method: 'GET',
                url: score.URL
            });


            return data;
        }
    }
    return factory;
}]);

You can only use

     Object& return_Object();

if the object returned has a greater scope than the function. For example, you can use it if you have a class where it is encapsulated. If you create an object in your function, use pointers. If you want to modify an existing object, pass it as an argument.

  class  MyClass{
      private:
        Object myObj;

      public:
         Object& return_Object() {

For reasonably modern versions of sed, edit the standard input to yield the standard output with

$ echo 't???? ß?ß??? ?? ??p??' | sed -E -e 's/[[:blank:]]+/\n/g'
t????
ß?ß???
??
??p??

If your vocabulary words are in files named lesson1 and lesson2, redirect sed’s standard output to the file all-vocab with

sed -E -e 's/[[:blank:]]+/\n/g' lesson1 lesson2 > all-vocab

What it means:

• The character class [[:blank:]] matches either a single space character or a single tab character.
  • Use [[:space:]] instead to match any single whitespace character (commonly space, tab, newline, carriage return, form-feed, and vertical tab).
  • The + quantifier means match one or more of the previous pattern.
  • So [[:blank:]]+ is a sequence of one or more characters that are all space or tab.
• The \n in the replacement is the newline that you want.
• The /g modifier on the end means perform the substitution as many times as possible rather than just once.
• The -E option tells sed to use POSIX extended regex syntax and in particular for this case the + quantifier. Without -E, your sed command becomes sed -e 's/[[:blank:]]\+/\n/g'. (Note the use of \+ rather than simple +.)

Perl Compatible Regexes

For those familiar with Perl-compatible regexes and a PCRE-capable sed, use \s+ to match runs of at least one whitespace character, as in

sed -E -e 's/\s+/\n/g' old > new

or

sed -e 's/\s\+/\n/g' old > new

These commands read input from the file old and write the result to a file named new in the current directory.

Maximum portability, maximum cruftiness

Going back to almost any version of sed since Version 7 Unix, the command invocation is a bit more baroque.

$ echo 't???? ß?ß??? ?? ??p??' | sed -e 's/[ \t][ \t]*/\
/g'
t????
ß?ß???
??
??p??

Notes:

• Here we do not even assume the existence of the humble + quantifier and simulate it with a single space-or-tab ([ \t]) followed by zero or more of them ([ \t]*).
• Similarly, assuming sed does not understand \n for newline, we have to include it on the command line verbatim.
  • The \ and the end of the first line of the command is a continuation marker that escapes the immediately following newline, and the remainder of the command is on the next line.
    • Note: There must be no whitespace preceding the escaped newline. That is, the end of the first line must be exactly backslash followed by end-of-line.
  • This error prone process helps one appreciate why the world moved to visible characters, and you will want to exercise some care in trying out the command with copy-and-paste.

Note on backslashes and quoting

The commands above all used single quotes ('') rather than double quotes (""). Consider:

$ echo '\\\\' "\\\\"
\\\\ \\

That is, the shell applies different escaping rules to single-quoted strings as compared with double-quoted strings. You typically want to protect all the backslashes common in regexes with single quotes.

I was trying to find the meaning of GRANT USAGE on *.* TO and found here. I can clarify that GRANT USAGE on *.* TO user IDENTIFIED BY PASSWORD password will be granted when you create the user with the following command (CREATE):

CREATE USER 'user'@'localhost' IDENTIFIED BY 'password'; 

When you grant privilege with GRANT, new privilege s will be added on top of it.

Library:

It is just a collection of routines (functional programming) or class definitions(object oriented programming). The reason behind is simply code reuse, i.e. get the code that has already been written by other developers. The classes or routines normally define specific operations in a domain specific area. For example, there are some libraries of mathematics which can let developer just call the function without redo the implementation of how an algorithm works.

Framework:

In framework, all the control flow is already there, and there are a bunch of predefined white spots that we should fill out with our code. A framework is normally more complex. It defines a skeleton where the application defines its own features to fill out the skeleton. In this way, your code will be called by the framework when appropriately. The benefit is that developers do not need to worry about if a design is good or not, but just about implementing domain specific functions.

Library,Framework and your Code image representation:

KeyDifference:

The key difference between a library and a framework is “Inversion of Control”. When you call a method from a library, you are in control. But with a framework, the control is inverted: the framework calls you. Source.

Relation:

Both of them defined API, which is used for programmers to use. To put those together, we can think of a library as a certain function of an application, a framework as the skeleton of the application, and an API is connector to put those together. A typical development process normally starts with a framework, and fill out functions defined in libraries through API.

This is what I tried for a right outer join [as per my requirement]:

m1 <- merge(x=companies, y=rounds2, by.x=companies$permalink, 
            by.y=rounds2$company_permalink, all.y=TRUE)
# Error in fix.by(by.x, x) : 'by' must specify uniquely valid columns
m1 <- merge(x=companies, y=rounds2, by.x=c("permalink"), 
            by.y=c("company_permalink"), all.y=TRUE)

This worked.

The thing that did the trick for me eventually was:

yum install gd gd-devel php-gd

and then restart apache:

service httpd restart

Fun problem! I'm going to have to rename a lot of apps soon, so I did a dry run.

This method allows progress to be made in atomic steps, to minimise disruption for other developers working on the app you're renaming.

See the link at the bottom of this answer for working example code.

1. Prepare existing code for the move:
   • Create an app config (set name and label to defaults).
   • Add the app config to INSTALLED_APPS.
   • On all models, explicitly set db_table to the current value.
   • Doctor migrations so that db_table was "always" explicitly defined.
   • Ensure no migrations are required (checks previous step).

2. Change the app label:

   • Set label in app config to new app name.
   • Update migrations and foreign keys to reference new app label.
   • Update templates for generic class-based views (the default path is <app_label>/<model_name>_<suffix>.html)

   • Run raw SQL to fix migrations and content_types app (unfortunately, some raw SQL is unavoidable). You can not run this in a migration.

     UPDATE django_migrations
        SET app = 'catalogue'
      WHERE app = 'shop';
     
     UPDATE django_content_type
        SET app_label = 'catalogue'
      WHERE app_label = 'shop';
     

   • Ensure no migrations are required (checks previous step).

3. Rename the tables:
   • Remove "custom" db_table.
   • Run makemigrations so django can rename the table "to the default".
4. Move the files:
   • Rename module directory.
   • Fix imports.
   • Update app config's name.
   • Update where INSTALLED_APPS references the app config.
5. Tidy up:
   • Remove custom app config if it's no longer required.
   • If app config gone, don't forget to also remove it from INSTALLED_APPS.

Example solution: I've created app-rename-example, an example project where you can see how I renamed an app, one commit at a time.

The example uses Python 2.7 and Django 1.8, but I'm confident the same process will work on at least Python 3.6 and Django 2.1.

As Joey pointed out, TortoiseSVN has a commandline syntax of its own. Unfortunately it is quite ugly, if you are used to svn commands, and it ignores the current working directory, thus it is not very usable - except for scripting.

I have created a little Python program (tsvn) which mimics the svn commandline syntax as closely as possible and calls TortoiseSVN accordingly. Thus, the difference between calling the normal commandline tools and calling TortoiseSVN is reduced to a little letter t at the beginning.

My tsvn program is not yet complete but already useful. It can be found in the cheeseshop (https://pypi.python.org/pypi/tsvn/)

In my case I had re-named the assembly that contained the code-first entity framework model. Although the actual schema hadn't changed at all the migrations table called

dbo.__MigrationHistory

contains a list of already performed migrations based on the old assembly name. I updated the old name in the migrations table to match the new and the migration then worked again.

I found the solution to this problem here: http://www.hildeberto.com/2008/05/hibernate-and-jersey-conflict-on.html

Unrelated to the question (Mehrdad's answer should get you going), and I hope this isn't taken as nitpicky: classes don't inherit interfaces, they implement them.

.NET does not support multiple-inheritance, so keeping the terms straight can help in communication. A class can inherit from one superclass and can implement as many interfaces as it wishes.

In response to Eric's comment... I had a discussion with another developer about whether or not interfaces "inherit", "implement", "require", or "bring along" interfaces with a declaration like:

public interface ITwo : IOne

The technical answer is that ITwo does inherit IOne for a few reasons:

• Interfaces never have an implementation, so arguing that ITwo implements IOne is flat wrong
• ITwo inherits IOne methods, if MethodOne() exists on IOne then it is also accesible from ITwo. i.e: ((ITwo)someObject).MethodOne()) is valid, even though ITwo does not explicitly contain a definition for MethodOne()
• ...because the runtime says so! typeof(IOne).IsAssignableFrom(typeof(ITwo)) returns true

We finally agreed that interfaces support true/full inheritance. The missing inheritance features (such as overrides, abstract/virtual accessors, etc) are missing from interfaces, not from interface inheritance. It still doesn't make the concept simple or clear, but it helps understand what's really going on under the hood in Eric's world :-)

In http nginx section (/etc/nginx/nginx.conf) add or modify:

keepalive_timeout 300s

In server nginx section (/etc/nginx/sites-available/your-config-file.com) add these lines:

client_max_body_size 50M;
fastcgi_buffers 8 1600k;
fastcgi_buffer_size 3200k;
fastcgi_connect_timeout 300s;
fastcgi_send_timeout 300s;
fastcgi_read_timeout 300s;

In php file in the case 127.0.0.1:9000 (/etc/php/7.X/fpm/pool.d/www.conf) modify:

request_terminate_timeout = 300

I hope help you.

This works:

switch (true) {
    case liCount == 0:
        setLayoutState('start');
        var api = $('#UploadList').data('jsp');
        api.reinitialise();
        break;
    case liCount<=5 && liCount>0:
        setLayoutState('upload1Row');
        var api = $('#UploadList').data('jsp');
        api.reinitialise();
        break;
    case liCount<=10 && liCount>5:
        setLayoutState('upload2Rows');
        var api = $('#UploadList').data('jsp');
        api.reinitialise();
        break;
    case liCount>10:
        var api = $('#UploadList').data('jsp');
        api.reinitialise();
        break;                  
}

A previous version of this answer considered the parentheses to be the culprit. In truth, the parentheses are irrelevant here - the only thing necessary is switch(true){...} and for your case expressions to evaluate to booleans.

It works because, the value we give to the switch is used as the basis to compare against. Consequently, the case expressions, also evaluating to booleans will determine which case is run. Could also turn this around, and pass switch(false){..} and have the desired expressions evaluate to false instead of true.. but personally prefer dealing with conditions that evaluate to truthyness. However, it does work too, so worth keeping in mind to understand what it is doing.

Eg: if liCount is 3, the first comparison is true === (liCount == 0), meaning the first case is false. The switch then moves on to the next case true === (liCount<=5 && liCount>0). This expression evaluates to true, meaning this case is run, and terminates at the break. I've added parentheses here to make it clearer, but they are optional, depending on the complexity of your expression.

It's pretty simple, and a neat way (if it fits with what you are trying to do) of handling a long series of conditions, where perhaps a long series of ìf() ... else if() ... else if () ... might introduce a lot of visual noise or fragility.

Use with caution, because it is a non-standard pattern, despite being valid code.

Just to top this up to the new Java 8 API:

DateTimeFormatter formatter = new DateTimeFormatterBuilder().appendPattern("MMMM dd, yyyy").toFormatter();
TemporalAccessor ta = formatter.parse("June 27, 2007");
Instant instant = LocalDate.from(ta).atStartOfDay().atZone(ZoneId.systemDefault()).toInstant();
Date d = Date.from(instant);
assertThat(d.getYear(), is(107));
assertThat(d.getMonth(), is(5));

A bit more verbose but you also see that the methods of Date used are deprecated ;-) Time to move on.

Even though Sheena's answer does the job, pip doesn't stop just there.

From Sheena's answer:

1. Download the package
2. unzip it if it is zipped
3. cd into the directory containing setup.py
4. If there are any installation instructions contained in documentation contained herein, read and follow the instructions OTHERWISE
5. type in python setup.py install

At the end of this, you'll end up with a .egg file in site-packages. As a user, this shouldn't bother you. You can import and uninstall the package normally. However, if you want to do it the pip way, you can continue the following steps.

In the site-packages directory,

6. unzip <.egg file>
7. rename the EGG-INFO directory as <pkg>-<version>.dist-info
8. Now you'll see a separate directory with the package name, <pkg-directory>
9. find <pkg-directory> > <pkg>-<version>.dist-info/RECORD
10. find <pkg>-<version>.dist-info >> <pkg>-<version>.dist-info/RECORD. The >> is to prevent overwrite.

Now, looking at the site-packages directory, you'll never realize you installed without pip. To uninstall, just do the usual pip uninstall <pkg>.

BATCH/CMD FILE like DateAndTime.cmd (not in CMD-Console)

Code:

SETLOCAL EnableDelayedExpansion
(set d=%date:~8,2%-%date:~3,2%-%date:~0,2%) & (set t=%time::=.%) & (set t=!t: =0!) & (set STAMP=!d!__!t!)

Create output:

echo %stamp%

Output:

2020-02-25__08.43.38.90

Or also possible in for lines in CMD-Console and BATCH/CMD File

set d=%date:~6,4%-%date:~3,2%-%date:~0,2%
set t=%time::=.%
set t=%t: =0%
set stamp=%d%__%t%

"Create output" and "Output" same as above

[(UITableViewCell *)[(UITableView *)self cellForRowAtIndexPath:nowIndex]

will give you uitableviewcell. But I am not sure what exactly you are asking for! Because you have this code and still you asking how to get uitableviewcell. Some more information will help to answer you :)

ADD: Here is an alternate syntax that achieves the same thing without the cast.

UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:nowIndex];

If I understand you question correctly, you could create a wrapper around your marquee and then assign a width (or max-width) to the wrapping element. For example:

<div id="marquee-wrapper">
    <div class="marquee">This is a marquee!</div>   
</div>

And then #marquee-wrapper { width: x }.

Object appears to be a more specific declaration than any. From the TypeScript spec (section 3):

All types in TypeScript are subtypes of a single top type called the Any type. The any keyword references this type. The Any type is the one type that can represent any JavaScript value with no constraints. All other types are categorized as primitive types, object types, or type parameters. These types introduce various static constraints on their values.

Also:

The Any type is used to represent any JavaScript value. A value of the Any type supports the same operations as a value in JavaScript and minimal static type checking is performed for operations on Any values. Specifically, properties of any name can be accessed through an Any value and Any values can be called as functions or constructors with any argument list.

Objects do not allow the same flexibility.

For example:

var myAny : any;

myAny.Something(); // no problemo

var myObject : Object;

myObject.Something(); // Error: The property 'Something' does not exist on value of type 'Object'.

If none of the other comments works, just do, open console line command and type:

document.oncontextmenu = null;

If you go to help>>check for updates it will tell you if there's an update.

You don't have to change from the stable channel. If you aren't offered an update and restart button, kindly close the window and try again. After about 4 or 5 checks like this, it will eventually show you update and restart button.

Why? because google.

I've read http://markdalgleish.com/2013/06/using-promises-in-angularjs-views/ [AngularJS allows us to streamline our controller logic by placing a promise directly on the scope, rather than manually handing the resolved value in a success callback.]

so simply and handy :)

var app = angular.module('myApp', []);
            app.factory('Data', function($http,$q) {
                return {
                    getData : function(){
                        var deferred = $q.defer();
                        var promise = $http.get('./largeLoad').success(function (response) {
                            deferred.resolve(response);
                        });
                        // Return the promise to the controller
                        return deferred.promise; 
                    }
                }
            });
            app.controller('FetchCtrl',function($scope,Data){
                $scope.items = Data.getData();
            });

Hope this help

I solved this in my env, without modify hadoop-env.sh

You'd be better using /bin/bash as default shell not /bin/sh

Check these before:

1. You have already config java and env (success echo $JAVA_HOME)
2. right config hadoop

echo $SHELL in every node, check if print /bin/bash if not, vi /etc/passwd, add /bin/bash at tail of your username ref

For my problem, I only needed to ensure that a user doesn't accidentally enter some text thus I tried to keep it simple and readable

isNumber() {
    (( $1 )) 2>/dev/null
}

According to the man page this pretty much does what I want

If the value of the expression is non-zero, the return status is 0

To prevent nasty error messages for strings that "might be numbers" I ignore the error output

$ (( 2s ))
bash: ((: 2s: value too great for base (error token is "2s")

The solution I've come up with is:

isinstance(y, (np.ndarray, np.generic) )

However, it's not 100% clear that all numpy types are guaranteed to be either np.ndarray or np.generic, and this probably isn't version robust.

Step 1: Ensure spawn is called the right way

First, review the docs for child_process.spawn( command, args, options ):

Launches a new process with the given command, with command line arguments in args. If omitted, args defaults to an empty Array.

The third argument is used to specify additional options, which defaults to:

{ cwd: undefined, env: process.env }

Use env to specify environment variables that will be visible to the new process, the default is process.env.

Ensure you are not putting any command line arguments in command and the whole spawn call is valid. Proceed to next step.

Step 2: Identify the Event Emitter that emits the error event

Search on your source code for each call to spawn, or child_process.spawn, i.e.

spawn('some-command', [ '--help' ]);

and attach there an event listener for the 'error' event, so you get noticed the exact Event Emitter that is throwing it as 'Unhandled'. After debugging, that handler can be removed.

spawn('some-command', [ '--help' ])
  .on('error', function( err ){ throw err })
;

Execute and you should get the file path and line number where your 'error' listener was registered. Something like:

/file/that/registers/the/error/listener.js:29
      throw err;
            ^
Error: spawn ENOENT
    at errnoException (child_process.js:1000:11)
    at Process.ChildProcess._handle.onexit (child_process.js:791:34)

If the first two lines are still

events.js:72
        throw er; // Unhandled 'error' event

do this step again until they are not. You must identify the listener that emits the error before going on next step.

Step 3: Ensure the environment variable $PATH is set

There are two possible scenarios:

1. You rely on the default spawn behaviour, so child process environment will be the same as process.env.
2. You are explicity passing an env object to spawn on the options argument.

In both scenarios, you must inspect the PATH key on the environment object that the spawned child process will use.

Example for scenario 1

// inspect the PATH key on process.env
console.log( process.env.PATH );
spawn('some-command', ['--help']);

Example for scenario 2

var env = getEnvKeyValuePairsSomeHow();
// inspect the PATH key on the env object
console.log( env.PATH );
spawn('some-command', ['--help'], { env: env });

The absence of PATH (i.e., it's undefined) will cause spawn to emit the ENOENT error, as it will not be possible to locate any command unless it's an absolute path to the executable file.

When PATH is correctly set, proceed to next step. It should be a directory, or a list of directories. Last case is the usual.

Step 4: Ensure command exists on a directory of those defined in PATH

Spawn may emit the ENOENT error if the filename command (i.e, 'some-command') does not exist in at least one of the directories defined on PATH.

Locate the exact place of command. On most linux distributions, this can be done from a terminal with the which command. It will tell you the absolute path to the executable file (like above), or tell if it's not found.

Example usage of which and its output when a command is found

> which some-command
some-command is /usr/bin/some-command

Example usage of which and its output when a command is not found

> which some-command
bash: type: some-command: not found

miss-installed programs are the most common cause for a not found command. Refer to each command documentation if needed and install it.

When command is a simple script file ensure it's accessible from a directory on the PATH. If it's not, either move it to one or make a link to it.

Once you determine PATH is correctly set and command is accessible from it, you should be able to spawn your child process without spawn ENOENT being thrown.

Works for me.

Just to expand on previous answers, a function to do this could work like this (changing the time and interval formats however you like them according to this for function.date, and this for DateInterval):

// Return adjusted start and end times as an array.

function expandTimeByMinutes( $time, $beforeMinutes, $afterMinutes ) {

    $time = DateTime::createFromFormat( 'H:i', $time );
    $time->sub( new DateInterval( 'PT' . ( (integer) $beforeMinutes ) . 'M' ) );
    $startTime = $time->format( 'H:i' );
    $time->add( new DateInterval( 'PT' . ( (integer) $beforeMinutes + (integer) $afterMinutes ) . 'M' ) );
    $endTime = $time->format( 'H:i' );

    return [
        'startTime' => $startTime,
        'endTime'   => $endTime,
    ];
}

$adjustedStartEndTime = expandTimeByMinutes( '10:00', 30, 30 );

echo '<h1>Adjusted Start Time: ' . $adjustedStartEndTime['startTime'] . '</h1>' . PHP_EOL . PHP_EOL;
echo '<h1>Adjusted End Time: '   . $adjustedStartEndTime['endTime']   . '</h1>' . PHP_EOL . PHP_EOL;

Lots of good answers here - just chipping in my own.

I had a requirement to parse a very specific JSON string, representing the results of making a web-API call. The JSON described a list of objects, and looked something like this:

[
   {
     "property1": "foo",
     "property2": "bar",
     "timeOfDay": "2019-09-30T00:00:00",
     "numberOfHits": 98,
     "isSpecial": false,
     "comment": "just to be awkward, this contains a comma"
   },

     "property1": "fool",

There are a few things to note about this:

1. The JSON should always describe a list (even if empty), which should only contain objects.
2. The objects in the list should only contain properties with simple types (string / date / number / boolean or null).
3. The value of a property may contain a comma - which makes parsing the JSON somewhat harder - but may not contain any quotes (because I'm too lazy to deal with that).

The ParseListOfObjects function in the code below takes the JSON string as input, and returns a Collection representing the items in the list. Each item is represented as a Dictionary, where the keys of the dictionary correspond to the names of the object's properties. The values are automatically converted to the appropriate type (String, Date, Double, Boolean - or Empty if the value is null).

Your VBA project will need a reference to the Microsoft Scripting Runtime library to use the Dictionary object - though it would not be difficult to remove this dependency if you use a different way of encoding the results.

Here's my JSON.bas:

A simple test:

Const strJSON As String = "[{""property1"":""foo""}]"
Dim oObjects As Collection: Set oObjects = Json.ParseListOfObjects(strJSON)

MsgBox oObjects(1)("property1") ' shows "foo"

Your first problem is that you are passing -3 to the 2nd parameter of Columns.Add. It needs to be -2 for it to auto-size the column. Source: http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.columns.aspx (look at the comments on the code example at the bottom)

private void initListView()
{
    // Add columns
    lvRegAnimals.Columns.Add("Id", -2,HorizontalAlignment.Left);
    lvRegAnimals.Columns.Add("Name", -2, HorizontalAlignment.Left);
    lvRegAnimals.Columns.Add("Age", -2, HorizontalAlignment.Left);
}

You can also use the other overload, Add(string). E.g:

lvRegAnimals.Columns.Add("Id");
lvRegAnimals.Columns.Add("Name");
lvRegAnimals.Columns.Add("Age");

Reference for more overloads: http://msdn.microsoft.com/en-us/library/system.windows.forms.listview.columnheadercollection.aspx

Second, to add items to the ListView, you need to create instances of ListViewItem and add them to the listView's Items collection. You will need to use the string[] constructor.

var item1 = new ListViewItem(new[] {"id123", "Tom", "24"});
var item2 = new ListViewItem(new[] {person.Id, person.Name, person.Age});
lvRegAnimals.Items.Add(item1);
lvRegAnimals.Items.Add(item2);

You can also store objects in the item's Tag property.

item2.Tag = person;

And then you can extract it

var person = item2.Tag as Person;

Let me know if you have any questions and I hope this helps!

Before using (strongly type html helper into view) this line

@Html.TextBoxFor(p => p.Product.Name)

You should include your model into you page for making strongly type view.

@model SampleModel

Use Regular expression to validate it.

isDate('2018-08-01T18:30:00.000Z');

isDate(_date){
        const _regExp  = new RegExp('^(-?(?:[1-9][0-9]*)?[0-9]{4})-(1[0-2]|0[1-9])-(3[01]|0[1-9]|[12][0-9])T(2[0-3]|[01][0-9]):([0-5][0-9]):([0-5][0-9])(.[0-9]+)?(Z)?$');
        return _regExp.test(_date);
    }

As mentioned, only arrays are allowed. But to make it simple for you, you could dynamically convert the object into an array via a piping function as seen here https://gist.github.com/brev/3949705

Just declare the filter, and add it to ng-repeat :)

<div ng-app="myApp">
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>
<div ng-controller="Main">
  <div ng-repeat="release in releases | object2Array | orderBy:'environment_id'">{{release.environment_id}}</div>
</div>

<script>

var app = angular.module('myApp', []).filter('object2Array', function() {
    return function(input) {
      var out = []; 
      for(i in input){
        out.push(input[i]);
      }
      return out;
    }
  })
.controller('Main',function ($scope) {
        $scope.releases = {"tvl-c-wbap001 + tvl-webapp":{"timestamp":" 05:05:53 PM ","environment_id":"CERT5","release_header":"Projects/Dev","date":"19 Oct","release":"12.11.91-1"},"tvl-c-wbap401 + tvl-webapp":{"timestamp":" 10:07:25 AM ","environment_id":"CERT4","release_header":"Future Release","date":"15 Oct","release":"485-1"},"tvl-c-wbap301 + tvl-webapp":{"timestamp":" 07:59:48 AM ","environment_id":"CERT3","release_header":"Next Release","date":"15 Oct","release":"485-1"},"tvl-c-wbap201 + tvl-webapp":{"timestamp":" 03:34:07 AM ","environment_id":"CERT2","release_header":"Next Changes","date":"15 Oct","release":"13.12.3-1"},"tvl-c-wbap101 + tvl-webapp":{"timestamp":" 12:44:23 AM ","environment_id":"CERT1","release_header":"Production Mirror","date":"15 Oct","release":"13.11.309-1"},"tvl-s-wbap002 + tvl-webapp":{"timestamp":" 12:43:23 AM ","environment_id":"Stage2","date":"15 Oct","release":"13.11.310-1"},"tvl-s-wbap001 + tvl-webapp":{"timestamp":" 11:07:38 AM ","environment_id":"Stage1","release_header":"Production Mirror","date":"11 Oct","release":"13.11.310-1"},"tvl-p-wbap001 + tvl-webapp":{"timestamp":" 11:39:25 PM ","environment_id":"Production","release_header":"Pilots","date":"14 Oct","release":"13.11.310-1"},"tvl-p-wbap100 + tvl-webapp":{"timestamp":" 03:27:53 AM ","environment_id":"Production","release_header":"Non Pilots","date":"11 Oct","release":"13.11.309-1"}}

I was having a similar error, it seems that the compiler misunderstand the call to the constructor without arguments. I made it work by removing the parenthesis from the variable declaration, in your code something like this:

class Foo
{
  public:
    Foo() {};
    Foo(int a) {};
    void bar() {};
};

int main()
{
  // this works...
  Foo foo1(1);
  foo1.bar();

  // this does not...
  Foo foo2; // Without "()" 
  foo2.bar();

  return 0;
}

Need to say, that if you are not in Activity, but in View (or have variable of View type in your scope), there is not need to use WINDOW_SERVICE. Then you can use at least two ways.

First:

DisplayMetrics dm = yourView.getContext().getResources().getDisplayMetrics();

Second:

DisplayMetrics dm = new DisplayMetrics();
yourView.getDisplay().getMetrics(dm);

All this methods we call here is not deprecated.

Another approach to draw a line programatically using ImageView

import android.app.Activity;
import android.graphics.Bitmap;
import android.graphics.Canvas;
import android.graphics.Color;
import android.graphics.Paint;
import android.graphics.Path;
import android.graphics.Typeface;
import android.os.Bundle;
import android.widget.ImageView;

public class Test extends Activity {
  ImageView drawingImageView;

  @Override
  public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    drawingImageView = (ImageView) this.findViewById(R.id.DrawingImageView);
    Bitmap bitmap = Bitmap.createBitmap((int) getWindowManager()
        .getDefaultDisplay().getWidth(), (int) getWindowManager()
        .getDefaultDisplay().getHeight(), Bitmap.Config.ARGB_8888);
    Canvas canvas = new Canvas(bitmap);
    drawingImageView.setImageBitmap(bitmap);

    // Line
    Paint paint = new Paint();
    paint.setColor(Color.GREEN);
    paint.setStrokeWidth(10);
    int startx = 50;
    int starty = 100;
    int endx = 150;
    int endy = 210;
    canvas.drawLine(startx, starty, endx, endy, paint);

  }
}

The problem is that there is no app installed to handle opening the PDF. You should use the Intent Chooser, like so:

File file = new File(Environment.getExternalStorageDirectory().getAbsolutePath() +"/"+ filename);
Intent target = new Intent(Intent.ACTION_VIEW);
target.setDataAndType(Uri.fromFile(file),"application/pdf");
target.setFlags(Intent.FLAG_ACTIVITY_NO_HISTORY);

Intent intent = Intent.createChooser(target, "Open File");
try {
    startActivity(intent);
} catch (ActivityNotFoundException e) {
    // Instruct the user to install a PDF reader here, or something
}   

You can use git cherry-pick to apply a single commit by itself to your current branch.

Example: git cherry-pick d42c389f

You can always use the DATALENGTH Function to determine if you have extra white space characters in text fields. This won't make the text visible but will show you where there are extra white space characters.

    SELECT DATALENGTH('MyTextData ') AS BinaryLength, LEN('MyTextData ') AS TextLength

This will produce 11 for BinaryLength and 10 for TextLength.

In a table your SQL would like this:

    SELECT * 
    FROM tblA
    WHERE DATALENGTH(MyTextField) > LEN(MyTextField)

This function is usable in all versions of SQL Server beginning with 2005.

I prefer approach of Tommy Carlier, but with a little change.

foreach (DataColumn column in row.Table.Columns)
    if (!row.IsNull(column))
      return false;

  return true;

I suppose this approach looks more simple and bright.

While other answers perfectly explained the question I will add some real life examples converting tensors to numpy array:

Example: Shared storage

PyTorch tensor residing on CPU shares the same storage as numpy array na

import torch
a = torch.ones((1,2))
print(a)
na = a.numpy()
na[0][0]=10
print(na)
print(a)

Output:

tensor([[1., 1.]])
[[10.  1.]]
tensor([[10.,  1.]])

Example: Eliminate effect of shared storage, copy numpy array first

To avoid the effect of shared storage we need to copy() the numpy array na to a new numpy array nac. Numpy copy() method creates the new separate storage.

import torch
a = torch.ones((1,2))
print(a)
na = a.numpy()
nac = na.copy()
nac[0][0]=10
?print(nac)
print(na)
print(a)

Output:

tensor([[1., 1.]])
[[10.  1.]]
[[1. 1.]]
tensor([[1., 1.]])

Now, just the nac numpy array will be altered with the line nac[0][0]=10, na and a will remain as is.

Example: CPU tensor with requires_grad=True

import torch
a = torch.ones((1,2), requires_grad=True)
print(a)
na = a.detach().numpy()
na[0][0]=10
print(na)
print(a)

Output:

tensor([[1., 1.]], requires_grad=True)
[[10.  1.]]
tensor([[10.,  1.]], requires_grad=True)

In here we call:

na = a.numpy() 

This would cause: RuntimeError: Can't call numpy() on Tensor that requires grad. Use tensor.detach().numpy() instead., because tensors that require_grad=True are recorded by PyTorch AD. Note that tensor.detach() is the new way for tensor.data.

This explains why we need to detach() them first before converting using numpy().

Example: CUDA tensor with requires_grad=False

a = torch.ones((1,2), device='cuda')
print(a)
na = a.to('cpu').numpy()
na[0][0]=10
print(na)
print(a)

Output:

tensor([[1., 1.]], device='cuda:0')
[[10.  1.]]
tensor([[1., 1.]], device='cuda:0')

?

Example: CUDA tensor with requires_grad=True

a = torch.ones((1,2), device='cuda', requires_grad=True)
print(a)
na = a.detach().to('cpu').numpy()
na[0][0]=10
?print(na)
print(a)

Output:

tensor([[1., 1.]], device='cuda:0', requires_grad=True)
[[10.  1.]]
tensor([[1., 1.]], device='cuda:0', requires_grad=True)

Without detach() method the error RuntimeError: Can't call numpy() on Tensor that requires grad. Use tensor.detach().numpy() instead. will be set.

Without .to('cpu') method TypeError: can't convert cuda:0 device type tensor to numpy. Use Tensor.cpu() to copy the tensor to host memory first. will be set.

You could use cpu() but instead of to('cpu') but I prefer the newer to('cpu').

If got your question right you want to do something like

update table
set identity_column_name = some value

Let me tell you, it is not an easy process and it is not advisable to use it, as there may be some foreign key associated on it.

But here are steps to do it, Please take a back-up of table

Step 1- Select design view of the table

Step 2- Turn off the identity column

Now you can use the update query.

Now redo the step 1 and step 2 and Turn on the identity column

Reference

To solve this issue the first thing you need to do is to get the last version of composer :

curl -sS https://getcomposer.org/installer | php

I recommend you to move the composer.phar file to a global “bin” directoy, in my case (OS X) the path is:

mv composer.phar /usr/local/bin/composer.phar

than you need to create an alias file for an easy access

alias composer='/usr/local/bin/composer.phar'

If everything is ok, now it is time to verify our Composer version:

composer --version

Let's make composer great again.

Using an ORDER BY in a subquery is not the best solution to this problem.

The best solution to get the max(post_date) by author is to use a subquery to return the max date and then join that to your table on both the post_author and the max date.

The solution should be:

SELECT p1.* 
FROM wp_posts p1
INNER JOIN
(
    SELECT max(post_date) MaxPostDate, post_author
    FROM wp_posts
    WHERE post_status='publish'
       AND post_type='post'
    GROUP BY post_author
) p2
  ON p1.post_author = p2.post_author
  AND p1.post_date = p2.MaxPostDate
WHERE p1.post_status='publish'
  AND p1.post_type='post'
order by p1.post_date desc

If you have the following sample data:

CREATE TABLE wp_posts
    (`id` int, `title` varchar(6), `post_date` datetime, `post_author` varchar(3))
;

INSERT INTO wp_posts
    (`id`, `title`, `post_date`, `post_author`)
VALUES
    (1, 'Title1', '2013-01-01 00:00:00', 'Jim'),
    (2, 'Title2', '2013-02-01 00:00:00', 'Jim')
;

The subquery is going to return the max date and author of:

MaxPostDate | Author
2/1/2013    | Jim

Then since you are joining that back to the table, on both values you will return the full details of that post.

See SQL Fiddle with Demo.

To expand on my comments about using a subquery to accurate return this data.

MySQL does not force you to GROUP BY every column that you include in the SELECT list. As a result, if you only GROUP BY one column but return 10 columns in total, there is no guarantee that the other column values which belong to the post_author that is returned. If the column is not in a GROUP BY MySQL chooses what value should be returned.

Using the subquery with the aggregate function will guarantee that the correct author and post is returned every time.

As a side note, while MySQL allows you to use an ORDER BY in a subquery and allows you to apply a GROUP BY to not every column in the SELECT list this behavior is not allowed in other databases including SQL Server.

In SQL Server Management Studio you can just right click the table in the object explorer and select "View Dependencies". This would give a you a good starting point. It shows tables, views, and procedures that reference the table.

You can use the for..in TypeScript operator to access the index when dealing with collections.

var test = [7,8,9];
for (var i in test) {
   console.log(i + ': ' + test[i]);
} 

Output:

 0: 7
 1: 8
 2: 9

See Demo

The rule is, if the function that is in the then handler returns a value, the promise resolves/rejects with that value, and if the function returns a promise, what happens is, the next then clause will be the then clause of the promise the function returned, so, in this case, the first example falls through the normal sequence of the thens and prints out values as one might expect, in the second example, the promise object that gets returned when you do Promise.resolve("bbb")'s then is the then that gets invoked when chaining(for all intents and purposes). The way it actually works is described below in more detail.

Quoting from the Promises/A+ spec:

The promise resolution procedure is an abstract operation taking as input a promise and a value, which we denote as [[Resolve]](promise, x). If x is a thenable, it attempts to make promise adopt the state of x, under the assumption that x behaves at least somewhat like a promise. Otherwise, it fulfills promise with the value x.

This treatment of thenables allows promise implementations to interoperate, as long as they expose a Promises/A+-compliant then method. It also allows Promises/A+ implementations to “assimilate” nonconformant implementations with reasonable then methods.

The key thing to notice here is this line:

if x is a promise, adopt its state [3.4]

you can use this code to scale image in required size.

+ (UIImage *)scaleImage:(UIImage *)image toSize:(CGSize)newSize
{
    CGSize actSize = image.size;
    float scale = actSize.width/actSize.height;

    if (scale < 1) {
        newSize.height = newSize.width/scale;
    } 
    else {
        newSize.width = newSize.height*scale;
    }

    UIGraphicsBeginImageContext(newSize);
    [image drawInRect:CGRectMake(0, 0, newSize.width, newSize.height)];
    UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return newImage;
}

Actually I think using plain slices is the best solution in this case:

for i in range(0, len(data), 100):
    chunk = data[i:i + 100]
    ...

If you want to avoid copying the slices, you could use itertools.islice(), but it doesn't seem to be necessary here.

The itertools() documentation also contains the famous "grouper" pattern:

def grouper(n, iterable, fillvalue=None):
    "grouper(3, 'ABCDEFG', 'x') --> ABC DEF Gxx"
    args = [iter(iterable)] * n
    return izip_longest(fillvalue=fillvalue, *args)

You would need to modify it to treat the last chunk correctly, so I think the straight-forward solution using plain slices is preferable.

Mostafa has already pointed out that such a method is trivial to write, and mkb gave you a hint to use the binary search from the sort package. But if you are going to do a lot of such contains checks, you might also consider using a map instead.

It's trivial to check if a specific map key exists by using the value, ok := yourmap[key] idiom. Since you aren't interested in the value, you might also create a map[string]struct{} for example. Using an empty struct{} here has the advantage that it doesn't require any additional space and Go's internal map type is optimized for that kind of values. Therefore, map[string] struct{} is a popular choice for sets in the Go world.

Are you talking about code within <script> tags, or in the HTML tag attributes, like this?

<a href="#" onclick="alert('this is inline JS');return false;">Click</a>

Either way, the debugger keyword like this will work:

<a href="#" onclick="debugger; alert('this is inline JS');return false;">Click</a>

N.B. Chrome won't pause at debuggers if the dev tools are not open.

You can also set property breakpoints in JS files and <script> tags:

1. Click the Sources tab
2. Click the Show Navigator icon and select the a file
3. Double-click the a line number in the left-hand margin. A corresponding row is added to the Breakpoints panel (4).

If you need to get all the files in the folder named 'Data', just code it as below

string[] Documents = System.IO.Directory.GetFiles("../../Data/");

Now the 'Documents' consists of array of complete object name of two text files in the 'Data' folder 'Data'.

Simply pass the sorted items from the dictionary to the plot() function. concentration.items() returns a list of tuples where each tuple contains a key from the dictionary and its corresponding value.

You can take advantage of list unpacking (with *) to pass the sorted data directly to zip, and then again to pass it into plot():

import matplotlib.pyplot as plt

concentration = {
    0: 0.19849878712984576,
    5000: 0.093917341754771386,
    10000: 0.075060643507712022,
    20000: 0.06673074282575861,
    30000: 0.057119318961966224,
    50000: 0.046134834546203485,
    100000: 0.032495766396631424,
    200000: 0.018536317451599615,
    500000: 0.0059499290585381479}

plt.plot(*zip(*sorted(concentration.items())))
plt.show()

sorted() sorts tuples in the order of the tuple's items so you don't need to specify a key function because the tuples returned by dict.item() already begin with the key value.

While Hash#has_key? gets the job done, as Matz notes here, it has been deprecated in favour of Hash#key?.

hash.key?(some_key)

How to convert date to string and to date again?

LocalDate.now().toString()

2017-01-23

…and…

LocalDate.parse( "2017-01-23" )

java.time

The Question uses troublesome old date-time classes bundled with the earliest versions of Java. Those classes are now legacy, supplanted by the java.time classes built into Java 8, Java 9, and later.

Determining today’s date requires a time zone. For any given moment the date varies around the globe by zone.

If not supplied by you, your JVM’s current default time zone is applied. That default can change at any moment during runtime, and so is unreliable. I suggest you always specify your desired/expected time zone.

ZoneId z = ZoneId.of( "America/Montreal" ) ;
LocalDate ld = LocalDate.now( z ) ;

ISO 8601

Your desired format of YYYY-MM-DD happens to comply with the ISO 8601 standard.

That standard happens to be used by default by the java.time classes when parsing/generating strings. So you can simply call LocalDate::parse and LocalDate::toString without specifying a formatting pattern.

String s = ld.toString() ;

To parse:

LocalDate ld = LocalDate.parse( s ) ;

About java.time

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

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

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

Where to obtain the java.time classes?

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

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

When using the for loop, the value of s is a Map.Entry element, meaning that you can get the key from s.key and the value from s.value
