The difference seems to be the amount of control you need over the animation.

The CATransition approach gives you more control and therefore more things to set up, eg. the timing function. Being an object, you can store it for later, refactor to point all your animations at it to reduce duplicated code, etc.

The UIView class methods are convenience methods for common animations, but are more limited than CATransition. For example, there are only four possible transition types (flip left, flip right, curl up, curl down). If you wanted to do a fade in, you'd have to either dig down to CATransition's fade transition, or set up an explicit animation of your UIView's alpha.

Note that CATransition on Mac OS X will let you specify an arbitrary CoreImage filter to use as a transition, but as it stands now you can't do this on the iPhone, which lacks CoreImage.

A very simple check you can do with Cell formulas:

Sheet 1 (new - old)

=(if(AND(Ref_New<>"";Ref_Old="");Ref_New;"")

Sheet 2 (old - new)

=(if(AND(Ref_Old<>"";Ref_New="");Ref_Old;"")

This formulas should work for an ENGLISH Excel. For other languages they need to be translated. (For German i can assist)

You need to open all three Excel Documents, then copy the first formula into A1 of your sheet 1 and the second into A1 of sheet 2. Now click in A1 of the first cell and mark "Ref_New", now you can select your reference, go to the new file and click in the A1, go back to sheet1 and do the same for "Ref_Old" with the old file. Replace also the other "Ref_New".

Doe the same for Sheet two.

Now copy the formaula form A1 over the complete range where zour data is in the old and the new file.

But two cases are not covered here:

1. In the compared cell of New and Old is the same data (Resulting Cell will be empty)
2. In the compared cell of New and Old is diffe data (Resulting Cell will be empty)

To cover this two cases also, you should create your own function, means learn VBA. A very useful Excel page is cpearson.com

Alternative answer to an older question refers to John Skeet's Library that has tools for letting you write primitive data types directly into a byte[] with an Index offset. Far better than BitConverter if you need performance.

Just download the source and look at the MiscUtil.Conversion namespace. EndianBitConverter.cs handles everything for you.

There is a very simple solution using dense_rank()

dense_rank() over (partition by [Mth] order by [UserAccountKey]) 
+ dense_rank() over (partition by [Mth] order by [UserAccountKey] desc) 
- 1

This will give you exactly what you were asking for: The number of distinct UserAccountKeys within each month.

@RequestMapping(value = "/books", method = { RequestMethod.GET, 
RequestMethod.POST })
public ModelAndView listBooks(@ModelAttribute("booksFilter") BooksFilter filter,
     HttpServletRequest request) 
    throws ParseException {

//your code 
}

This will works for both GET and POST.

For GET if your pojo(BooksFilter) have to contain the attribute which you're using in request parameter

like below

public class BooksFilter{

private String parameter1;
private String parameter2;

   //getters and setters

URl should be like below

/books?parameter1=blah

Like this way u can use it for both GET and POST

You could use search or match for this.

str.search( 'Yes' )

will return the position of the match, or -1 if it isn't found.

The limitation relates to the simplified CommonJS syntax vs. the normal callback syntax:

• http://requirejs.org/docs/whyamd.html#commonjscompat
• https://github.com/jrburke/requirejs/wiki/Differences-between-the-simplified-CommonJS-wrapper-and-standard-AMD-define

Loading a module is inherently an asynchronous process due to the unknown timing of downloading it. However, RequireJS in emulation of the server-side CommonJS spec tries to give you a simplified syntax. When you do something like this:

var foomodule = require('foo');
// do something with fooModule

What's happening behind the scenes is that RequireJS is looking at the body of your function code and parsing out that you need 'foo' and loading it prior to your function execution. However, when a variable or anything other than a simple string, such as your example...

var module = require(path); // Call RequireJS require

...then Require is unable to parse this out and automatically convert it. The solution is to convert to the callback syntax;

var moduleName = 'foo';
require([moduleName], function(fooModule){
    // do something with fooModule
})

Given the above, here is one possible rewrite of your 2nd example to use the standard syntax:

define(['dyn_modules'], function (dynModules) {
    require(dynModules, function(){
        // use arguments since you don't know how many modules you're getting in the callback
        for (var i = 0; i < arguments.length; i++){
            var mymodule = arguments[i];
            // do something with mymodule...
        }
    });

});

EDIT: From your own answer, I see you're using underscore/lodash, so using _.values and _.object can simplify the looping through arguments array as above.

I generally write these kind of utilities to operate on the name of the variable, rather than the variable value, primarily because bash can't otherwise pass variables by reference.

Here's a version that works with the name of the array:

function array_contains # array value
{
    [[ -n "$1" && -n "$2" ]] || {
        echo "usage: array_contains <array> <value>"
        echo "Returns 0 if array contains value, 1 otherwise"
        return 2
    }

    eval 'local values=("${'$1'[@]}")'

    local element
    for element in "${values[@]}"; do
        [[ "$element" == "$2" ]] && return 0
    done
    return 1
}

With this, the question example becomes:

array_contains A "one" && echo "contains one"

etc.

This is a well-known issue and based on this answer you could add setLenient:

Gson gson = new GsonBuilder()
        .setLenient()
        .create();

Retrofit retrofit = new Retrofit.Builder()
        .baseUrl(BASE_URL)
        .client(client)
        .addConverterFactory(GsonConverterFactory.create(gson))
        .build();

Now, if you add this to your retrofit, it gives you another error:

com.google.gson.JsonSyntaxException: java.lang.IllegalStateException: Expected BEGIN_OBJECT but was STRING at line 1 column 1 path $

This is another well-known error you can find answer here (this error means that your server response is not well-formatted); So change server response to return something:

{
    android:[
        { ver:"1.5", name:"Cupcace", api:"Api Level 3" }
        ...
    ]
}

For better comprehension, compare your response with Github api.

Suggestion: to find out what's going on to your request/response add HttpLoggingInterceptor in your retrofit.

Based on this answer your ServiceHelper would be:

private ServiceHelper() {
        httpClient = new OkHttpClient.Builder();
        HttpLoggingInterceptor interceptor = new HttpLoggingInterceptor();
        interceptor.setLevel(HttpLoggingInterceptor.Level.BODY);
        httpClient.interceptors().add(interceptor);
        Retrofit retrofit = createAdapter().build();
        service = retrofit.create(IService.class);
    }

Also don't forget to add:

compile 'com.squareup.okhttp3:logging-interceptor:3.3.1'

First change the array to a string by using implode() function. E.g $number=array(1,2,3,4,5,...); $stringofnumber=implode("|",$number); then pass the string to a session. e.g $_SESSION['string']=$stringofnumber; so when you go to the page where you want to use the array, just explode your string. e.g $number=explode("|", $_SESSION['string']); finally number is your array but remember to start array on the of each page.

int i = 100;
char c = (char)i;

There is no way to append one char to another. But you can create an array of chars and use it.

Look at the WSGI reference implementation. You already have it in your Python libraries. It's quite simple.

For this your android application must have uploaded into the android market. when you upload it on the android market then use the following code to open the market with your android application.

    Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("market://details?id=<packagename>"));
startActivity(intent);

If you want it to download and install from your own server then use the following code

Intent intent = new Intent(Intent.ACTION_VIEW,Uri.parse("http://www.example.com/sample/test.apk"));
    startActivity(intent);

you can do like this:

String str = "Jamaica";
str = str.substring(1, title.length());
return str;

or in general:

public String removeFirstChar(String str){
   return str.substring(1, title.length());
}

Ben has told you how to revert a merge commit, but it's very important you realize that in doing so

"...declares that you will never want the tree changes brought in by the merge. As a result, later merges will only bring in tree changes introduced by commits that are not ancestors of the previously reverted merge. This may or may not be what you want." (git-merge man page).

An article/mailing list message linked from the man page details the mechanisms and considerations that are involved. Just make sure you understand that if you revert the merge commit, you can't just merge the branch again later and expect the same changes to come back.

This is not a shorthand for $(document).ready().

Each one is a different type execution.

• ExecuteScalar is going to be the type of query which will be returning a single value.

  An example would be returning a generated id after inserting.

  INSERT INTO my_profile (Address) VALUES ('123 Fake St.'); SELECT CAST(scope_identity() AS int)

• ExecuteReader gives you a data reader back which will allow you to read all of the columns of the results a row at a time.

  An example would be pulling profile information for one or more users.

  SELECT * FROM my_profile WHERE id = '123456'

• ExecuteNonQuery is any SQL which isn't returning values, but is actually performing some form of work like inserting deleting or modifying something.

  An example would be updating a user's profile in the database.

  UPDATE my_profile SET Address = '123 Fake St.' WHERE id = '123456'

Short answer

__all__ affects from <module> import * statements.

Long answer

Consider this example:

foo
+-- bar.py
+-- __init__.py

In foo/__init__.py:

• (Implicit) If we don't define __all__, then from foo import * will only import names defined in foo/__init__.py.

• (Explicit) If we define __all__ = [], then from foo import * will import nothing.

• (Explicit) If we define __all__ = [ <name1>, ... ], then from foo import * will only import those names.

Note that in the implicit case, python won't import names starting with _. However, you can force importing such names using __all__.

You can view the Python document here.

my rule of thumb is:

rebase for branches with the same name, merge otherwise.

examples for same names would be master, origin/master and otherRemote/master.

if develop exists only in the local repository, and it is always based on a recent origin/master commit, you should call it master, and work there directly. it simplifies your life, and presents things as they actually are: you are directly developing on the master branch.

if develop is shared, it should not be rebased on master, just merged back into it with --no-ff. you are developing on develop. master and develop have different names, because we want them to be different things, and stay separate. do not make them same with rebase.

Use TcpView to see ports listening and connections. This will not give you the requests though.

In order to see requests, you need reverse of a proxy which I do not know of any such tools.

Use tracing to give you parts of the requests (first 1KB of the request).

One important thing to mention as well is the security improvement that comes with the package-lock file. Since it keeps all the hashes of the packages if someone would tamper with the public npm registry and change the source code of a package without even changing the version of the package itself it would be detected by the package-lock file.

I wrote a script that does exactly this:

https://github.com/chovy/node-startup

I have not tried with forever, but you can customize the command it runs, so it should be straight forward:

/etc/init.d/node-app start
/etc/init.d/node-app restart
/etc/init.d/node-app stop

The response provided by Ranveer (second answer above) absolutely does NOT work.

He says to use col-xx-offset-#, but that is not how offsets are used.

If you wasted your time trying to use col-xx-offset-#, as I did based on his answer, the solution is to use offset-xx-#.

It works for me. Your data object is probably nil and, as rckoenes noted, the root object should be a (mutable) array. See this code:

NSString *jsonString = @"[{\"id\": \"1\", \"name\":\"Aaa\"}, {\"id\": \"2\", \"name\":\"Bbb\"}]";
NSData *jsonData = [jsonString dataUsingEncoding:NSUTF8StringEncoding];
NSError *e = nil;
NSMutableArray *json = [NSJSONSerialization JSONObjectWithData:jsonData options:NSJSONReadingMutableContainers error:&e];
NSLog(@"%@", json);

(I had to escape the quotes in the JSON string with backslashes.)

I came across this as well, for me this has worked (covers most browsers):

myString.replace(/[\s\uFEFF\xA0]/g, ';');

Inspired by this trim polyfill after hitting some bumps: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/String/trim#Polyfill

Perhaps a more pythonic way of doing so.

from numpy import *
import math
import matplotlib.pyplot as plt

t = linspace(0,2*math.pi,400)
a = sin(t)
b = cos(t)
c = a + b

plt.plot(t, a, t, b, t, c)
plt.show()

So KevZero requested a less kludgy solution, so I came up with the following:

Here's an example:

$ dmesg|tail | sed -r 's#^\[([0-9]+\.[0-9]+)\](.*)#echo -n "[";echo -n $(date --date="@$(echo "$(grep btime /proc/stat|cut -d " " -f 2)+\1" | bc)" +"%c");echo -n "]";echo -n "\2"#e'

If you want it to perform a bit better, put the timestamp from proc into a variable instead :)

I didn't know, but found the question interesting. So I dug in the android code... Thanks open-source :)

The screen you show is DateTimeSettings. The checkbox "Use network-provided values" is associated to the shared preference String KEY_AUTO_TIME = "auto_time"; and also to Settings.System.AUTO_TIME

This settings is observed by an observed called mAutoTimeObserver in the 2 network ServiceStateTrackers: GsmServiceStateTracker and CdmaServiceStateTracker.

Both implementations call a method called revertToNitz() when the settings becomes true. Apparently NITZ is the equivalent of NTP in the carrier world.

Bottom line: You can set the time to the value provided by the carrier thanks to revertToNitz(). Unfortunately, I haven't found a mechanism to get the network time. If you really need to do this, I'm afraid, you'll have to copy these ServiceStateTrackers implementations, catch the intent raised by the framework (I suppose), and add a getter to mSavedTime.

li:nth-child(1n) { color:green; }_x000D_

  <li>list element 2</li>_x000D_

</ul>

See browser support here : CSS3 :nth-child() Selector

datetime has fields hour and minute. So to get the hours and minutes, you would use t1.hour and t1.minute.

However, when you subtract two datetimes, the result is a timedelta, which only has the days and seconds fields. So you'll need to divide and multiply as necessary to get the numbers you need.

Use the rename utility:

rc@bvm3:/tmp/foo $ touch 05_h.png 06_h.png
rc@bvm3:/tmp/foo $ rename 's/_h/_half/' *

Since I'm missing this option in the list of provided answers I'd like to add an eligible option as of 2020: docker or any equivalent container platform. In addition to ensuring your application is working in a stable environment there are additional security benefits as well as improved portability.

There is docker support for Windows, macOS and most/major Linux distributions. Installing docker on a supported platform is rather straight-forward and well-documented. Setting up a Node.js application is as simple as putting it in a container and running that container while making sure its being restarted after shutdown.

Create Container Image

Assuming your application is available in /home/me/my-app on that server, create a text file Dockerfile in folder /home/me/my-app with content similar to this one:

FROM node:lts-alpine
COPY /my-app /app
CMD ["/app/server.js"]

Create the image using command like this:

docker build -t myapp-as-a-service /home/me

Note: Last parameter is selecting folder containing that Dockerfile instead of the Dockerfile itself. You may pick a different one using option -f.

Start Container

Use this command for starting the container:

docker run -d --restart always -p 80:3000 myapp-as-a-service

This command is assuming your app is listening on port 3000 and you want it to be exposed on port 80 of your host.

This is a very limited example for sure, but it's a good starting point.

Also, note that XDocument is supported in Xbox 360 and Windows Phone OS 7.0. If you target them, develop for XDocument or migrate from XmlDocument.

                    var src = myLatLng;//start point
                    var des = myLatLng;// should be the destination
                    path.push(src);
                    poly.setPath(path);
                    service.route({
                        origin: src,

                            }
                        }
                    });

                }
                ;

                    lng = Math.random() + orlong;
                    console.log(lat + "-" + lng);
                    myLatLng = new google.maps.LatLng(lat, lng);
                    movepointer(map, marker);

                }, 1000);



            },
            error: function() {
                $('#frame').html('Sorry, no details found');
            },
        });
        return false;
    }
    $(function() {
        $("#frame").draggable();
    });

The easiest answer: jQuery. Do something like this:

$(document).ready(function(){
   var $form = $('form');
   $form.submit(function(){
      $.post($(this).attr('action'), $(this).serialize(), function(response){
            // do something here on success
      },'json');
      return false;
   });
});

If you want to add content dynamically and still need it to work, and also with more than one form, you can do this:

   $('form').live('submit', function(){
      $.post($(this).attr('action'), $(this).serialize(), function(response){
            // do something here on success
      },'json');
      return false;
   });

$('div[id ^= "player_"]');

This worked for me..select all Div starts with "players_" keyword and display it.

You can either use what SiegeX said above or if you aren't interested in learning/using parameter expansion, you can use:

for filename in $(ls /home/user/);
do
    echo $filename
done;

http://jdpgrailsdev.github.io/blog/2014/09/09/spring_data_hibernate_join.html
from this link:

if you are using JPA on top of Hibernate, there is no way to set the FetchMode used by Hibernate to JOINHowever, if you are using JPA on top of Hibernate, there is no way to set the FetchMode used by Hibernate to JOIN.

The Spring Data JPA library provides a Domain Driven Design Specifications API that allows you to control the behavior of the generated query.

final long userId = 1;

final Specification<User> spec = new Specification<User>() {
   @Override
    public Predicate toPredicate(final Root<User> root, final 
     CriteriaQuery<?> query, final CriteriaBuilder cb) {
    query.distinct(true);
    root.fetch("permissions", JoinType.LEFT);
    return cb.equal(root.get("id"), userId);
 }
};

List<User> users = userRepository.findAll(spec);

^[A-Za-z](\W|\w)*

(\W|\w) will ensure that every subsequent letter is word(\w) or non word(\W)

instead of (\W|\w)* you can also use .* where . means absolutely anything just like (\w|\W)

df.dropna(subset=['columnName1', 'columnName2'])

This is what I use:

var result = [];
for (var l in someObject){
  if (someObject.hasOwnProperty(l){
    result.push(l+': '+someObject[l]);
  }
}
alert(result.join('\n'));

If you want to show nested objects too, you could use something recursive:

function alertObject(obj){
 var result = [];
 function traverse(obj){
 for (var l in obj){
   if (obj.hasOwnProperty(l)){
     if (obj[l] instanceof Object){
       result.push(l+'=>[object]');
       traverse(obj[l]);
     } else {
       result.push(l+': '+obj[l]);
     }
   }
  }
 }
 traverse(obj);
 return result;
}

For people who want to use multiple images of course importing them one by one would be a problem. The solution is to move the images folder to the public folder. So if you had an image at public/images/logo.jpg, you could display that image this way:

function Header() {
  return (
    <div>
      <img src="images/logo.jpg" alt="logo"/>
    </div>
  );
}

Yes, no need to use /public/ in the source.

Read further: https://daveceddia.com/react-image-tag/.

The syntax to store the command output into a variable is var=$(command).

So you can directly do:

result=$(ls -l | grep -c "rahul.*patle")

And the variable $result will contain the number of matches.

seekbar.setOnSeekBarChangeListener(new OnSeekBarChangeListener() {

            @Override
            public void onStopTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onStartTrackingTouch(SeekBar seekBar) {

            }

            @Override
            public void onProgressChanged(SeekBar seekBar, int progress,
                    boolean fromUser) {

                int MIN = 5;
                if (progress < MIN) {

                    value.setText(" Time Interval (" + seektime + " sec)");
                } else {
                    seektime = progress;
                }
                value.setText(" Time Interval (" + seektime + " sec)");

            }
        });

PORT 4369: Erlang makes use of a Port Mapper Daemon (epmd) for resolution of node names in a cluster. Nodes must be able to reach each other and the port mapper daemon for clustering to work.

PORT 35197 set by inet_dist_listen_min/max Firewalls must permit traffic in this range to pass between clustered nodes

RabbitMQ Management console:

• PORT 15672 for RabbitMQ version 3.x
• PORT 55672 for RabbitMQ pre 3.x

PORT 5672 RabbitMQ main port.

For a cluster of nodes, they must be open to each other on 35197, 4369 and 5672.

For any servers that want to use the message queue, only 5672 is required.

The best way is to use display:

inline-block; 

and

overflow: hidden;

In more simple terms:

Technically, the -u flag adds a tracking reference to the upstream server you are pushing to.

What is important here is that this lets you do a git pull without supplying any more arguments. For example, once you do a git push -u origin master, you can later call git pull and git will know that you actually meant git pull origin master.

Otherwise, you'd have to type in the whole command.

I think the MatTableDataSource object is some way linked with the data array that you pass to MatTableDataSource constructor.

For instance:

dataTable: string[];
tableDS: MatTableDataSource<string>;

ngOnInit(){
   // here your pass dataTable to the dataSource
   this.tableDS = new MatTableDataSource(this.dataTable); 
}

So, when you have to change data; change on the original list dataTable and then reflect the change on the table by call _updateChangeSubscription() method on tableDS.

For instance:

this.dataTable.push('testing');
this.tableDS._updateChangeSubscription();

That's work with me through Angular 6.

As an alternative you can also query the information_schema database and retrieve the data from the global_variables (and global_status of course too). This approach provides the same information, but gives you the opportunity to do more with the results, as it is a plain old query.

For example you can convert units to become more readable. The following query provides the current global setting for the innodb_log_buffer_size in bytes and megabytes:

SELECT
  variable_name,
  variable_value AS innodb_log_buffer_size_bytes,
  ROUND(variable_value / (1024*1024)) AS innodb_log_buffer_size_mb
FROM information_schema.global_variables
WHERE variable_name LIKE  'innodb_log_buffer_size';

As a result you get:

+------------------------+------------------------------+---------------------------+
| variable_name          | innodb_log_buffer_size_bytes | innodb_log_buffer_size_mb |
+------------------------+------------------------------+---------------------------+
| INNODB_LOG_BUFFER_SIZE | 268435456                    |                       256 |
+------------------------+------------------------------+---------------------------+

useEffect can hook on a certain prop or state. so, the thing you need to do to avoid infinite loop hook is binding some variable or state to effect

For Example:

useEffect(myeffectCallback, [])

above effect will fire only once the component has rendered. this is similar to componentDidMount lifecycle

const [something, setSomething] = withState(0)
const [myState, setMyState] = withState(0)
useEffect(() => {
  setSomething(0)
}, myState)

above effect will fire only my state has changed this is similar to componentDidUpdate except not every changing state will fire it.

You can read more detail though this link

Another way to solve the issue:

If you are using the support library, you need to add the appcompat lib to the project. This link shows how to add the support lib to your project.

Assuming you have added the support lib earlier but you are getting the mentioned issue, you can follow the steps below to fix that.

1. Right click on the project and navigate to Build Path > Configure Build Path.

2. On the left side of the window, select Android. You will see something like this:

3. You can notice that no library is referenced at the moment. Now click on the Add button shown at the bottom-right side. You will see a pop up window as shown below.

4. Select the appcompat lib and press OK. (Note: The lib will be shown if you have added them as mentioned earlier). Now you will see the following window:

5. Press OK. That's it. The lib is now added to your project (notice the red mark) and the errors relating inclusion of support lib must be gone.

v35G will select everything from the cursor up to line 35.

v puts you in select mode, 35 specifies the line number that you want to G go to.

You could also use v} which will select everything up to the beginning of the next paragraph.

Warning: function() expects parameter X to be boolean (or integer, string, etc)

If the wrong type of parameter is passed to a function – and PHP cannot convert it automatically – a warning is thrown. This warning identifies which parameter is the problem, and what data type is expected. The solution: change the indicated parameter to the correct data type.

For example this code:

echo substr(["foo"], 23);

Results in this output:

PHP Warning: substr() expects parameter 1 to be string, array given

Ink-Jet is right. More specifically, an .o (.obj) -- or object file is a single source file compiled in to machine code (I'm not sure if the "machine code" is the same or similar to an executable machine code). Ultimately, it's an intermediate between an executable program and plain-text source file.

The linker uses the o files to assemble the file executable.

Wikipedia may have more detailed information. I'm not sure how much info you'd like or need.

In Ruby, any variable whose name starts with a capital letter is a constant and you can only assign to it once. Choose one of these alternatives:

class MyClass
  MYCONSTANT = "blah"

  def mymethod
    MYCONSTANT
  end
end

class MyClass
  def mymethod
    my_constant = "blah"
  end
end

While others have pointed out it is not possible to override constructors syntactically, I would like to also point out, it would be conceptually bad to do so. Say the superclass is a dog object, and the subclass is a Husky object. The dog object has properties such as "4 legs", "sharp nose", if "override" means erasing dog and replacing it with Husky then Husky would be missing these properties and be a broken object. Husky never had those properties and simply inherited them from dog. On the other hand, if you intend to give Husky everything that dog has, then conceptually you could "override" dog with Husky, but there would be no point in creating a class that is the same as dog, it's not practically an inherited class but a complete replacement.

No you can't they are different. When the app was deployed your controller mappings would be borked for example.

Why do you want to anyway, a controller is not a service, and vice versa.

If you don't mind getting a new data frame object returned as opposed to updating the original Pandas .assign() will avoid SettingWithCopyWarning. Your example:

df = df.assign(B=df1['E'])

Tested this code using XCode 8 and Swift 3

I'm posting this answer to give insights into multiple ways available for you to change the project on GCP. I will also explain when to use each of the following options.

Option 1: Cloud CLI - Set Project Property on Cloud SDK on CLI

Use this option, if you want to run all Cloud CLI commands on a specific project.

gcloud config set project <Project-ID>

With this, the selected project on Cloud CLI will change, and the currently selected project is highlighted in yellow.

Option 2: Cloud CLI - Set Project ID flag with most Commands

Use this command if you want to execute commands on multiple projects. Eg: create clusters in one project, and use the same configs to create on another project. Use the following flag for each command.

--project <Project-ID>

Option 3: Cloud CLI - Initialize the Configurations in CLI

This option can be used if you need separate configurations for different projects/accounts. With this, you can easily switch between configurations by using the activate command. Eg: gcloud config configurations activate <congif-name>.

gcloud init

Option 4: Open new Cloud Shell with your preferred project

This is preferred if you don't like to work with CLI commands. Press the PLUS + button for a new tab.

Next, select your preferred project.

I think you've answered your own question: try not to go beyond the 70 Mb limit, however it really depends on many things: what iOS version you're using (not SDK), how many applications running in background, what exact memory you're using etc.

Just avoid the instant memory splashes (e.g. you're using 40 Mb of RAM, and then allocating 80 Mb's more for some short computation). In this case iOS would kill your application immediately.

You should also consider lazy loading of assets (load them only when you really need and not beforehand).

List<string> empnames = emplist.Select(e => e.Ename).ToList();

This is an example of Projection in Linq. Followed by a ToList to resolve the IEnumerable<string> into a List<string>.

Alternatively in Linq syntax (head compiled):

var empnamesEnum = from emp in emplist 
                   select emp.Ename;
List<string> empnames = empnamesEnum.ToList();

Projection is basically representing the current type of the enumerable as a new type. You can project to anonymous types, another known type by calling constructors etc, or an enumerable of one of the properties (as in your case).

For example, you can project an enumerable of Employee to an enumerable of Tuple<int, string> like so:

var tuples = emplist.Select(e => new Tuple<int, string>(e.EID, e.Ename));

one has not been assigned so points to an unpredictable location. You should either place it on the stack:

Vector one;
one.a = 12;
one.b = 13;
one.c = -11

or dynamically allocate memory for it:

Vector* one = malloc(sizeof(*one))
one->a = 12;
one->b = 13;
one->c = -11
free(one);

Note the use of free in this case. In general, you'll need exactly one call to free for each call made to malloc.

Looks like the answer above was a little incomplete try the following:-

=RIGHT(A2,(LEN(A2)-(LEN(A2)-1)))

Obviously, this is for cell A2...

What this does is uses a combination of Right and Len - Len is the length of a string and in this case, we want to remove all but one from that... clearly, if you wanted the last two characters you'd change the -1 to -2 etc etc etc.

After the length has been determined and the portion of that which is required - then the Right command will display the information you need.

This works well combined with an IF statement - I use this to find out if the last character of a string of text is a specific character and remove it if it is. See, the example below for stripping out commas from the end of a text string...

=IF(RIGHT(A2,(LEN(A2)-(LEN(A2)-1)))=",",LEFT(A2,(LEN(A2)-1)),A2)

For okhttp3 this has changed a bit.

Now you set up the times using the builder, and not setters, like this:

OkHttpClient client = new OkHttpClient.Builder()
        .connectTimeout(10, TimeUnit.SECONDS)
        .writeTimeout(10, TimeUnit.SECONDS)
        .readTimeout(30, TimeUnit.SECONDS)
        .build();

More info can be found in their wiki: https://github.com/square/okhttp/blob/b3dcb9b1871325248fba917458658628c44ce8a3/docs/recipes.md#timeouts-kt-java

I'm preferred my own way to synchronize all Visual Studio Code extensions between laptops, using .dotfiles and small script to perform updates automatically. This way helps me every time when I want to install all extensions I have without any single mouse activity in Visual Studio Code after installing (via Homebrew).

So I just write each new added extension to .txt file stored at my .dotfiles folder. After that I pull master branch on another laptop to get up-to-date file with all extensions.

Using the script, which Big Rich had written before, with one more change, I can totally synchronise all extensions almost automatically.

Script

cat dart-extensions.txt | xargs -L 1 code --install-extension

And also there is one more way to automate that process. Here you can add a script which looks up a Visual Studio Code extension in realtime and each time when you take a diff between the code --list-extensions command and your .txt file in .dotfiles, you can easily update your file and push it to your remote repository.

The error "Cannot read property 'map' of undefined" will be encountered if there is an error in the "this.props.data" or there is no props.data array.

Better put condition to check the the array like

if(this.props.data){
this.props.data.map(........)
.....
}

In my opinion, it is not possible for the like button (and I hope it is not possible).

But, you can trigger a custom OpenGraph v2 action, or display a like button linked to your facebook page.

You can place .gitignore in any directory in git.

It's commonly used as a placeholder file in folders, since folders aren't usually tracked by git.

Mat image1;
IplImage* image2=cvCloneImage(&(IplImage)image1);

Guess this will do the job.

Edit: If you face compilation errors, try this way:

cv::Mat image1;
IplImage* image2;
image2 = cvCreateImage(cvSize(image1.cols,image1.rows),8,3);
IplImage ipltemp=image1;
cvCopy(&ipltemp,image2);

You can see all the privileges for all directories wit the following

SELECT *
from all_tab_privs
where table_name in
  (select directory_name 
   from dba_directories);

The following gives you the sql statements to grant the privileges should you need to backup what you've done or something

select 'Grant '||privilege||' on directory '||table_schema||'.'||table_name||' to '||grantee 
from all_tab_privs 
where table_name in (select directory_name from dba_directories);

Use the DELETE statement

Delete From <TableName>

Eg:

Delete from Student;

One way to do it would be to do the hover effect when the touch starts, then remove the hover effect when the touch moves or ends.

This is what Apple has to say about touch handling in general, since you mention iPhone.

You need to check your project settings, under C++, check include directories and make sure it points to where GameEngine.h resides, the other issue could be that GameEngine.h is not in your source file folder or in any include directory and resides in a different folder relative to your project folder. For instance you have 2 projects ProjectA and ProjectB, if you are including GameEngine.h in some source/header file in ProjectA then to include it properly, assuming that ProjectB is in the same parent folder do this:

include "../ProjectB/GameEngine.h"

This is if you have a structure like this:

Root\ProjectA

Root\ProjectB <- GameEngine.h actually lives here

Here we can have alt_elem method which can fit in your for loop.

def alt_elem(list, index=2):
    for i, elem in enumerate(list, start=1):
        if not i % index:
           yield tuple(list[i-index:i])


a = range(10)
for index in [2, 3, 4]:
    print("With index: {0}".format(index))
    for i in alt_elem(a, index):
       print(i)

Output:

With index: 2
(0, 1)
(2, 3)
(4, 5)
(6, 7)
(8, 9)
With index: 3
(0, 1, 2)
(3, 4, 5)
(6, 7, 8)
With index: 4
(0, 1, 2, 3)
(4, 5, 6, 7)

Note: Above solution might not be efficient considering operations performed in func.

its very true on oracle as well as sql is "users" is a reserved words just change it , it will serve u the best if u like change it to this

UPDATE system_info set field_value = 'NewValue' 

FROM system_users users JOIN system_info info ON users.role_type = info.field_desc where users.user_name = 'uname'

OS X alternative: The solution described earlier based on [[NSProcessInfo processInfo] processorCount] is only available on OS X 10.5.0, according to the docs. For earlier versions of OS X, use the Carbon function MPProcessors().

If you're a Cocoa programmer, don't be freaked out by the fact that this is Carbon. You just need to need to add the Carbon framework to your Xcode project and MPProcessors() will be available.

The classic response is, "You don't." You test the public API of Foo, not its internals.

Is there any behavior of the Foo object (or, less good, some other object in the environment) that is affected by foo()? If so, test that. And if not, what does the method do?

Use purrr::has_element to check against the value of a list element:

> x <- list(c(1, 2), c(3, 4))
> purrr::has_element(x, c(3, 4))
[1] TRUE
> purrr::has_element(x, c(3, 5))
[1] FALSE

I was getting this same error, but for me this was due to a method in a base class (in Project A) having the output type changed from a non-void type to void. A child class existed in Project B (which I didn't want used and had marked obsolete) that I missed when performing this update and hence started throwing this error.

In PL/SQL, there is a trick to use the undocumented OWA_UTIL.ITE function.

SET SERVEROUTPUT ON

DECLARE
    x   VARCHAR2(10);
BEGIN
    x := owa_util.ite('a' = 'b','T','F');
    dbms_output.put_line(x);
END;

Try this:

DateTime.Now.ToString("yyyy-MM-ddThh:mm:sszzz");

zzz is the timezone offset.

You can use the auto_now and auto_now_add options for updated_at and created_at respectively.

class MyModel(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

I got into this mess twice and after searching long and hard and following what others did absolutely nothing worked for me but to uninstall and install IIS back once on Windows 7 machine and then on Windows server 2012 R2.

I believe you should escape the dot. Try:

String filename = "D:/some folder/001.docx";
String extensionRemoved = filename.split("\\.")[0];

Otherwise dot is interpreted as any character in regular expressions.

I think it is dangerous to use $.isEmptyObject from jquery to check whether the array is empty, as @jesenko mentioned. I just met that problem.

In the isEmptyObject doc, it mentions:

The argument should always be a plain JavaScript Object

which you can determine by $.isPlainObject. The return of $.isPlainObject([]) is false.

I've found that you can use any subset condition for a given column by wrapping it in []. For instance, you have a df with columns ['Product','Time', 'Year', 'Color']

And let's say you want to include products made before 2014. You could write,

df[df['Year'] < 2014]

To return all the rows where this is the case. You can add different conditions.

df[df['Year'] < 2014][df['Color' == 'Red']

Then just choose the columns you want as directed above. For instance, the product color and key for the df above,

df[df['Year'] < 2014][df['Color'] == 'Red'][['Product','Color']]

Since Git uses curl under the hood, you can use ~/.netrc file with the credentials. For GitHub it would look something like this:

machine github.com
  login <github username>
  password <password OR github access token>

If you choose to use access tokens, it can be generated from:

Settings -> Developer settings -> Personal access tokens

This should also work if you are using Github Enterprise in your own corporation. just put your enterprise github url in the machine field.

I've fixed like this, with this "$(input).prop('readonly',true);" in beforeShow

Ex:

$('input.datepicker').datepicker(
                        {   
                            changeMonth: false,
                            changeYear: false,
                            beforeShow: function(input, instance) { 
                                $(input).datepicker('setDate', new Date());
                                $(input).prop('readonly',true);
                            }
                        }                         
                     ); 

I know question is already answered.

But let me add one point here. This is not only case of true or false. See below:

var val="Do";

Var c= (val == "Do" || val == "Done")
          ? 7
          : 0

Here if val is Do or Done then c will be 7 else it will be zero. In this case c will be 7.

This is actually another perspective of this operator.

I see that they did not understand your question.

Answer is: add "traditional" parameter to your ajax call like this:

$.ajax({
  traditional: true,
  type: "POST",
  url: url,
  data: custom,
  success: ok,
  dataType: "json"
});

And it will work with parameters PASSED AS A STRING.

You can use:

RadioButton rb = (RadioButton) findViewById(rg.getCheckedRadioButtonId());

Answers above elucidated many things, but I think it is useful to make a conceptual distinction.

What if you take a perfectly on-focus picture of a blurred image?

The blurring detection problem is only well posed when you have a reference. If you need to design, e.g., an auto-focus system, you compare a sequence of images taken with different degrees of blurring, or smoothing, and you try to find the point of minimum blurring within this set. I other words you need to cross reference the various images using one of the techniques illustrated above (basically--with various possible levels of refinement in the approach--looking for the one image with the highest high-frequency content).

OK, this question has been answered and answer accepted but someone asked me to put my answer so there you go.

First of all, it is not possible to say for sure. It is an internal implementation detail and not documented. However, based on the objects included in the other object. Now, how do we calculate the memory requirement for our cached objects?

I had previously touched this subject in this article:

Now, how do we calculate the memory requirement for our cached objects? Well, as most of you would know, Int32 and float are four bytes, double and DateTime 8 bytes, char is actually two bytes (not one byte), and so on. String is a bit more complex, 2*(n+1), where n is the length of the string. For objects, it will depend on their members: just sum up the memory requirement of all its members, remembering all object references are simply 4 byte pointers on a 32 bit box. Now, this is actually not quite true, we have not taken care of the overhead of each object in the heap. I am not sure if you need to be concerned about this, but I suppose, if you will be using lots of small objects, you would have to take the overhead into consideration. Each heap object costs as much as its primitive types, plus four bytes for object references (on a 32 bit machine, although BizTalk runs 32 bit on 64 bit machines as well), plus 4 bytes for the type object pointer, and I think 4 bytes for the sync block index. Why is this additional overhead important? Well, let’s imagine we have a class with two Int32 members; in this case, the memory requirement is 16 bytes and not 8.

OpenOffice.org can view HTML tables. Simply use the open command on the HTML file, or select and copy the table in your browser and then Paste Special in OpenOffice.org. It will query you for the file type, one of which should be HTML. Select that and voila!

My Approach with the help of Java8 , Passing coma separated roles will give you true or false

    public static Boolean hasAnyPermission(String permissions){
    Boolean result = false;
    if(permissions != null && !permissions.isEmpty()){
        String[] rolesArray = permissions.split(",");
        Authentication authentication = SecurityContextHolder.getContext().getAuthentication();
        for (String role : rolesArray) {
            boolean hasUserRole = authentication.getAuthorities().stream().anyMatch(r -> r.getAuthority().equals(role));
            if (hasUserRole) {
                result = true;
                break;
            }
        }
    }
    return result;
}

Well, I think nginx by itself doesn't have that in its setup, because the Ubuntu-maintained package does it as a convention to imitate Debian's apache setup. You could create it yourself if you wanted to emulate the same setup.

Create /etc/nginx/sites-available and /etc/nginx/sites-enabled and then edit the http block inside /etc/nginx/nginx.conf and add this line

include /etc/nginx/sites-enabled/*;

Of course, all the files will be inside sites-available, and you'd create a symlink for them inside sites-enabled for those you want enabled.

While executing the job we need to pass Job parameters as follows:

JobParameters jobParameters= new JobParametersBuilder().addString("file.name", "filename.txt").toJobParameters();   
JobExecution execution = jobLauncher.run(job, jobParameters);  

by using the expression language we can import the value as follows:

 #{jobParameters['file.name']}

String filePath = Environment.getExternalStorageDirectory()+"/yourfolderNAme/yopurfile.mp3";
mediaPlayer = new  MediaPlayer();
mediaPlayer.setDataSource(filePath);
mediaPlayer.prepare();   
mediaPlayer.start()

and this play from raw folder.

int resID = myContext.getResources().getIdentifier(playSoundName,"raw",myContext.getPackageName());

            MediaPlayer mediaPlayer = MediaPlayer.create(myContext,resID);
            mediaPlayer.prepare();
            mediaPlayer.start();

mycontext=application.this. use.

Let me give some information on them:

1. quit() simply raises the SystemExit exception.

   Furthermore, if you print it, it will give a message:

   >>> print (quit)
   Use quit() or Ctrl-Z plus Return to exit
   >>>
   

   This functionality was included to help people who do not know Python. After all, one of the most likely things a newbie will try to exit Python is typing in quit.

   Nevertheless, quit should not be used in production code. This is because it only works if the site module is loaded. Instead, this function should only be used in the interpreter.

2. exit() is an alias for quit (or vice-versa). They exist together simply to make Python more user-friendly.

   Furthermore, it too gives a message when printed:

   >>> print (exit)
   Use exit() or Ctrl-Z plus Return to exit
   >>>
   

   However, like quit, exit is considered bad to use in production code and should be reserved for use in the interpreter. This is because it too relies on the site module.

3. sys.exit() also raises the SystemExit exception. This means that it is the same as quit and exit in that respect.

   Unlike those two however, sys.exit is considered good to use in production code. This is because the sys module will always be there.

4. os._exit() exits the program without calling cleanup handlers, flushing stdio buffers, etc. Thus, it is not a standard way to exit and should only be used in special cases. The most common of these is in the child process(es) created by os.fork.

   Note that, of the four methods given, only this one is unique in what it does.

Summed up, all four methods exit the program. However, the first two are considered bad to use in production code and the last is a non-standard, dirty way that is only used in special scenarios. So, if you want to exit a program normally, go with the third method: sys.exit.

Or, even better in my opinion, you can just do directly what sys.exit does behind the scenes and run:

raise SystemExit

This way, you do not need to import sys first.

However, this choice is simply one on style and is purely up to you.

Another similar method to those described above is to use plt.ylim for example:

plt.ylim(max(y_array), min(y_array))

This method works for me when I'm attempting to compound multiple datasets on Y1 and/or Y2

The logic here is not quite correct, you need to check every letter to determine if the word is a palindrome. Currently, you print multiple times. What about doing something like:

function checkPalindrome(word) {    
    var l = word.length;
    for (var i = 0; i < l / 2; i++) {
        if (word.charAt(i) !== word.charAt(l - 1 - i)) {
            return false;
        }
    }
    return true;
}

if (checkPalindrome("1122332211")) {
    document.write("The word is a palindrome");
} else {
    document.write("The word is NOT a palindrome");
}

Which should print that it IS indeed a palindrome.

Warning: The option below is not relevant to Bootstrap v3.0.x, as scrolling in those versions has been explicitly confined to the modal itself. If you disable wheel events you may inadvertently prevent some users from viewing the content in modals that have heights greater than the viewport height.

Yet Another Option: Wheel Events

The scroll event is not cancelable. However it is possible to cancel the mousewheel and wheel events. The big caveat is that not all legacy browsers support them, Mozilla only recently adding support for the latter in Gecko 17.0. I don't know the full spread, but IE6+ and Chrome do support them.

Here's how to leverage them:

$('#myModal')
  .on('shown', function () {
    $('body').on('wheel.modal mousewheel.modal', function () {
      return false;
    });
  })
  .on('hidden', function () {
    $('body').off('wheel.modal mousewheel.modal');
  });

I finally got it:

You can use Character.isDigit(char ch) method or you can also use regular expression.

Below is the snippet:

public class CheckDigit {

private static Scanner input;

public static void main(String[] args) {

    System.out.print("Enter a String:");
    input = new Scanner(System.in);
    String str = input.nextLine();

    if (CheckString(str)) {
        System.out.println(str + " is numeric");
    } else {
        System.out.println(str +" is not numeric");
    }
}

public static boolean CheckString(String str) {
    for (char c : str.toCharArray()) {
        if (!Character.isDigit(c))
            return false;
    }
    return true;
}

}

How to turn 4 spaces indents in all files in VS Code to 2 spaces

• Open file search
• Turn on Regular Expressions
• Enter: ( {2})(?: {2})(\b|(?!=[,'";\.:\*\\\/\{\}\[\]\(\)])) in the search field

For caching, I would use OkHttp interceptors to gain control over caching policy. Check out this sample that's included in the OkHttp library.

RewriteResponseCacheControl.java

Here's how I'd use it with Picasso -

OkHttpClient okHttpClient = new OkHttpClient();
    okHttpClient.networkInterceptors().add(new Interceptor() {
        @Override
        public Response intercept(Chain chain) throws IOException {
            Response originalResponse = chain.proceed(chain.request());
            return originalResponse.newBuilder().header("Cache-Control", "max-age=" + (60 * 60 * 24 * 365)).build();
        }
    });

    okHttpClient.setCache(new Cache(mainActivity.getCacheDir(), Integer.MAX_VALUE));
    OkHttpDownloader okHttpDownloader = new OkHttpDownloader(okHttpClient);
    Picasso picasso = new Picasso.Builder(mainActivity).downloader(okHttpDownloader).build();
    picasso.load(imageURL).into(viewHolder.image);

If you need any type of quoting (single, double, and triple for both) you can "combine"(0) the strings:

>>> raw_string_with_quotes = r'double"' r"single'" r'''double triple""" ''' r"""single triple''' """
>>> print raw_string_with_quotes
double"single'double triple""" single triple'''

You may also "combine"(0) raw strings with non-raw strings:

>>> r'raw_string\n' 'non-raw string\n'
'raw_string\\nnon-raw string\n'

(0): In fact, the Python parser joins the strings, and it does not create multiple strings. If you add the "+" operator, then multiple strings are created and combined.

from datetime import datetime, timedelta

nine_hours_from_now = datetime.now() + timedelta(hours=9)
#datetime.datetime(2012, 12, 3, 23, 24, 31, 774118)

And then use string formatting to get the relevant pieces:

>>> '{:%H:%M:%S}'.format(nine_hours_from_now)
'23:24:31'

If you're only formatting the datetime then you can use:

>>> format(nine_hours_from_now, '%H:%M:%S')
'23:24:31'

Or, as @eumiro has pointed out in comments - strftime

The above answer is great or if it will not hurt you, just rollback the migration and change the name and run migration again.

 php artisan migrate:rollback

Makefile part of the question

This is pretty easy, unless you don't need to generalize try something like the code below (but replace space indentation with tabs near g++)

SRC_DIR := .../src
OBJ_DIR := .../obj
SRC_FILES := $(wildcard $(SRC_DIR)/*.cpp)
OBJ_FILES := $(patsubst $(SRC_DIR)/%.cpp,$(OBJ_DIR)/%.o,$(SRC_FILES))
LDFLAGS := ...
CPPFLAGS := ...
CXXFLAGS := ...

main.exe: $(OBJ_FILES)
   g++ $(LDFLAGS) -o $@ $^

$(OBJ_DIR)/%.o: $(SRC_DIR)/%.cpp
   g++ $(CPPFLAGS) $(CXXFLAGS) -c -o $@ $<

Automatic dependency graph generation

A "must" feature for most make systems. With GCC in can be done in a single pass as a side effect of the compilation by adding -MMD flag to CXXFLAGS and -include $(OBJ_FILES:.o=.d) to the end of the makefile body:

CXXFLAGS += -MMD
-include $(OBJ_FILES:.o=.d)

And as guys mentioned already, always have GNU Make Manual around, it is very helpful.

if (ConfigurationManager.AppSettings.AllKeys.Contains("myKey"))
{

You could use jQuery to show the div, and set it at wherever your mouse is:

html:

  <head>
    <link href="style.css" rel="stylesheet" />
    <script src="https://code.jquery.com/jquery-3.3.1.min.js"></script>
  </head>

  <body>
    <div id="trigger">
      <h1>Hover me!</h1>
      <p>Ill show you wonderful things</p>
    </div>
    <div id="secret">
     shhhh
    </div>
    <script src="script.js"></script>
  </body>

</html>

styles:

#trigger {
  border: 1px solid black;
}
#secret {
  display:none;
  top:0;  
  position:absolute;
  background: grey;
  color:white;
  width: 50%;
}

js:

$("#trigger").hover(function(e){
    $("#secret").show().css('top', e.pageY + "px").css('left', e.pageX + "px");
  },function(e){
    $("#secret").hide()
})

Basically destroy runs any callbacks on the model while delete doesn't.

From the Rails API:

• ActiveRecord::Persistence.delete

  Deletes the record in the database and freezes this instance to reflect that no changes should be made (since they can't be persisted). Returns the frozen instance.

  The row is simply removed with an SQL DELETE statement on the record's primary key, and no callbacks are executed.

  To enforce the object's before_destroy and after_destroy callbacks or any :dependent association options, use #destroy.

• ActiveRecord::Persistence.destroy

  Deletes the record in the database and freezes this instance to reflect that no changes should be made (since they can't be persisted).

  There's a series of callbacks associated with destroy. If the before_destroy callback return false the action is cancelled and destroy returns false. See ActiveRecord::Callbacks for further details.

Random r = new Random();
int i1 = r.nextInt(45 - 28) + 28;

This gives a random integer between 28 (inclusive) and 45 (exclusive), one of 28,29,...,43,44.

Using ES6: There are many ways to search for strings and replace in JavaScript. One of them is as follow

const findFor = ['<', '>', '\n'];_x000D_
_x000D_
const replaceWith = ['&lt;', '&gt;', '<br/>'];_x000D_
_x000D_
const originalString = '<strong>Hello World</strong> \n Let\'s code';_x000D_
_x000D_
let modifiedString = originalString;_x000D_
_x000D_
findFor.forEach( (tag, i) => modifiedString = modifiedString.replace(new RegExp(tag, "g"), replaceWith[i]) )_x000D_
_x000D_
console.log('Original String: ', originalString);_x000D_
console.log('Modified String: ', modifiedString);

The problem was the box "open new connection" that was checked. So I couldn't use my temporary table.

The put method in HashMap is defined like this:

Object  put(Object key, Object value) 

key is the first parameter, so in your put, "one" is the key. You can't easily look up by value in a HashMap, if you really want to do that, it would be a linear search done by calling entrySet(), like this:

for (Map.Entry<Object, Object> e : hashmap.entrySet()) {
    Object key = e.getKey();
    Object value = e.getValue();
}

However, that's O(n) and kind of defeats the purpose of using a HashMap unless you only need to do it rarely. If you really want to be able to look up by key or value frequently, core Java doesn't have anything for you, but something like BiMap from the Google Collections is what you want.

If you select the input by the id and then add the input[readonly="readonly"] tag in the css, something like:

 #inputID input[readonly="readonly"] {
     background-color: #000000;
 }

That will not work. You have to select a parent class or id an then the input. Something like:

 .parentClass, #parentID input[readonly="readonly"] {
     background-color: #000000;
 }

My 2 cents while waiting for new tickets at work :D

Thanks everybody, here is the most succinct explanation I found on the MSDN site:

// y = x, unless x is null, in which case y = -1.
int y = x ?? -1;

The best practice is to explicitly list the columns:

Insert Into TableName(col1, col2,col2) Values(?, ?, ?)

Otherwise, your original insert will break if you add another column to your table.

While many of you have touched upon major adv./dis of linked list vs array, most of the comparisons are how one is better/ worse than the other.Eg. you can do random access in array but not possible in linked list and others. However, this is assuming link lists and array are going to be applied in a similar application. However a correct answer should be how link list would be preferred over array and vice-versa in a particular application deployment. Suppose you want to implement a dictionary application, what would you use ? Array : mmm it would allow easy retrieval through binary search and other search algo .. but lets think how link list can be better..Say you want to search "Blob" in dictionary. Would it make sense to have a link list of A->B->C->D---->Z and then each list element also pointing to an array or another list of all words starting with that letter ..

A -> B -> C -> ...Z
|    |    |
|    |    [Cat, Cave]
|    [Banana, Blob]
[Adam, Apple]

Now is the above approach better or a flat array of [Adam,Apple,Banana,Blob,Cat,Cave] ? Would it even be possible with array ? So a major advantage of link list is you can have an element not just pointing to the next element but also to some other link list/array/ heap/ or any other memory location. Array is a one flat contigous memory sliced into blocks size of the element it is going to store.. Link list on the other hand is a chunks of non-contigous memory units (can be any size and can store anything) and pointing to each other the way you want. Similarly lets say you are making a USB drive. Now would you like files to be saved as any array or as a link list ? I think you get the idea what I am pointing to :)

String courseID = "Comp-101";
List<String> scores = new ArrayList<String> ();
scores.add("100");
scores.add("90");
scores.add("80");
scores.add("97");

Map<String, ArrayList<String>> myMap = new HashMap<String, ArrayList<String>>();
myMap.put(courseID, scores);

Hope this helps!

I solve the problem by changing the 'Provisioning Profile' in the same section ('Code Signing') from Automatic to 'MyProvisioningProfile name'

I came across this issue when not using async/await on a asynchronous function (api call). Hence adding them / using the promise handlers properly cleared the error.

This is just the syntax of the case statement, it looks like this.

SELECT 
  CASE 
    WHEN FRUIT = 'A' THEN 'APPLE' 
    WHEN FRUIT = 'B' THEN 'BANANA'     
  END AS FRUIT
FROM FRUIT_TABLE;

As a reminder remember; no assignment is performed the value becomes the column contents. (If you wanted to assign that to a variable you would put it before the CASE statement).

I suggest to use "return false" instead of useing some javascript in the href-tag:

<form id="">
...
</form>

<a href="#" onclick="document.getElementById('myform').submit(); return false;">send form</a>

The V1 git man page had a reference about un-applying a stash. The excerpt is below.

The newer V2 git man page doesn't include any reference to un-applying a stash but the below still works well

Un-applying a Stash In some use case scenarios you might want to apply stashed changes, do some work, but then un-apply those changes that originally came from the stash. Git does not provide such a stash un-apply command, but it is possible to achieve the effect by simply retrieving the patch associated with a stash and applying it in reverse:

$ git stash show -p stash@{0} | git apply -R

Again, if you don’t specify a stash, Git assumes the most recent stash:

$ git stash show -p | git apply -R

You may want to create an alias and effectively add a stash-unapply command to your Git. For example:

$ git config --global alias.stash-unapply '!git stash show -p | git apply -R'
$ git stash apply
$ #... work work work
$ git stash-unapply

I had the same issue, but I just wrapped the arguments like this and it works now.

    $args = array();
    $args['Header'] = array(
        'CustomerCode' => 'dsadsad',
        'Language' => 'fdsfasdf'
    );
    $args['RequestObject'] = $whatever;

    // this was the catch, double array with "Request"
    $response = $this->client->__soapCall($name, array(array( 'Request' => $args )));

Using this function:

 print_r($this->client->__getLastRequest());

You can see the Request XML whether it's changing or not depending on your arguments.

Use [ trace = 1, exceptions = 0 ] in SoapClient options.

u can use this :

@Override
        public void afterTextChanged(Editable s) {
            super.afterTextChanged(s);
            if (s.length() == Bank.PAN_MINIMUM_RECOGNIZABLE_LENGTH + 10) {
                Bank bank = BankUtil.findByPan(s.toString());
                if (null != bank && mNewPanEntered && !mNameDefined) {
                    mNewPanEntered = false;
                    suggestCardName(bank);
                }

private void suggestCardName(Bank bank) {
    mLastSuggestTime = System.currentTimeMillis();
    if (!bank.getName().trim().matches(getActivity().getString(R.string.bank_eghtesadnovin))) {
        inputCardNumber.setError(R.string.balance_not_enmb, true);

    }
}

The reason expr[expr[2] == 'hesc'] doesn't work is that for a data frame, x[y] selects columns, not rows. If you want to select rows, change to the syntax x[y,] instead:

> expr[expr[2] == 'hesc',]
  expr_value cell_type
4   5.929771      hesc
5   5.873096      hesc
6   5.665857      hesc

It's done by binding to the scroll event of the container (usually window).

Quick example:

// Cache selectors
var topMenu = $("#top-menu"),
    topMenuHeight = topMenu.outerHeight()+15,
    // All list items
    menuItems = topMenu.find("a"),
    // Anchors corresponding to menu items
    scrollItems = menuItems.map(function(){
      var item = $($(this).attr("href"));
      if (item.length) { return item; }
    });

// Bind to scroll
$(window).scroll(function(){
   // Get container scroll position
   var fromTop = $(this).scrollTop()+topMenuHeight;

   // Get id of current scroll item
   var cur = scrollItems.map(function(){
     if ($(this).offset().top < fromTop)
       return this;
   });
   // Get the id of the current element
   cur = cur[cur.length-1];
   var id = cur && cur.length ? cur[0].id : "";
   // Set/remove active class

See the above in action at jsFiddle including scroll animation.

This applies if you are using it with an authguard

this.router.events.subscribe(event => {
        if(event instanceof NavigationStart){
            console.log('this is what your looking for ', event.url);  
         }
       } 
   );

I tried very hard with System.ComponentModel.TypeDescriptor without success. That does not means it can't work but I would like to see code for that.

In counter part, I wanted to change some Attribute values. I did 2 functions which work fine for that purpose.

        // ************************************************************************
        public static void SetObjectPropertyDescription(this Type typeOfObject, string propertyName,  string description)
        {
            PropertyDescriptor pd = TypeDescriptor.GetProperties(typeOfObject)[propertyName];
            var att = pd.Attributes[typeof(DescriptionAttribute)] as DescriptionAttribute;
            if (att != null)
            {
                var fieldDescription = att.GetType().GetField("description", BindingFlags.NonPublic | BindingFlags.Instance);
                if (fieldDescription != null)
                {
                    fieldDescription.SetValue(att, description);
                }
            }
        }

        // ************************************************************************
        public static void SetPropertyAttributReadOnly(this Type typeOfObject, string propertyName, bool isReadOnly)
        {
            PropertyDescriptor pd = TypeDescriptor.GetProperties(typeOfObject)[propertyName];
            var att = pd.Attributes[typeof(ReadOnlyAttribute)] as ReadOnlyAttribute;
            if (att != null)
            {
                var fieldDescription = att.GetType().GetField("isReadOnly", BindingFlags.NonPublic | BindingFlags.Instance);
                if (fieldDescription != null)
                {
                    fieldDescription.SetValue(att, isReadOnly);
                }
            }
        }

If you want to check quietly via $? without the hassle of grep'ing wget's output you can use:

wget -q "http://blah.meh.com/my/path" -O /dev/null

Works even on URLs with just a path but has the disadvantage that something's really downloaded so this is not recommended when checking big files for existence.

I would suggest this: https://medium.com/@AustinMatherne/angular-let-directive-a168d4248138

This directive allow you to write something like:

<div *ngLet="'myVal' as myVar">
  <span> {{ myVar }} </span>
</div>

Since PHP 5.5, you can use array_column:

$ids = array_column($users, 'id');

This is the preferred option on any modern project. However, if you must support PHP<5.5, the following alternatives exist:

Since PHP 5.3, you can use array_map with an anonymous function, like this:

$ids = array_map(function ($ar) {return $ar['id'];}, $users);

Before ^{_{(Technically PHP 4.0.6+)}}, you must create an anonymous function with create_function instead:

$ids = array_map(create_function('$ar', 'return $ar["id"];'), $users);

The easiest way is to redirect the output of the echo by >>:

echo 'VNCSERVERS="1:root"' >> /etc/sysconfig/configfile
echo 'VNCSERVERARGS[1]="-geometry 1600x1200"' >> /etc/sysconfig/configfile

If You want the Path After successful installation then first open you CMD and type python or python -i

It Will Open interactive shell for You and Then type

import sys

sys.executable

Hit enter and you will get path where your python is installed ...

in keyword allows you to loop over a collection and check if there is a member in the collection that is equal to the element.

In this case string is nothing but a list of characters:

dog = "xdasds"
if "x" in dog:
     print "Yes!"

You can check a substring too:

>>> 'x' in "xdasds"
True
>>> 'xd' in "xdasds"
True
>>> 
>>> 
>>> 'xa' in "xdasds"
False

Think collection:

>>> 'x' in ['x', 'd', 'a', 's', 'd', 's']
True
>>> 

You can also test the set membership over user defined classes.

For user-defined classes which define the __contains__ method, x in y is true if and only if y.__contains__(x) is true.

This is the best and easy way to import font from google and
this is also a standard method to import font

Paste this code on your index page or on header

<link href='http://fonts.googleapis.com/css?family=Oswald:400,300,700' rel='stylesheet' type='text/css'>

other method is to import on css like this:

@import url(http://fonts.googleapis.com/css?family=Oswald:400,300,700);

on your Css file as this code

body {
  font-family: 'Oswald', sans-serif !important;
}

Note : The @import code line will be the first lines in your css file (style.css, etc.css). They can be used in any of the .css files and should always be the first line in these files. The following is an example:

Just Use

import  qs from "qs";
 let data = {
        'profileId': this.props.screenProps[0],
        'accountId': this.props.screenProps[1],
        'accessToken': this.props.screenProps[2],
        'itemId': this.itemId
    };
    return axios.post(METHOD_WALL_GET, qs.stringify(data))

JavaScript is a scripting language, not a HTMLanguage type. It is mainly to do process at background and it needs document.write to display things on browser. Also if your document.write exceeds one line, make sure to put concatenation + at the end of each line.

Example

<script type="text/javascript">
if(document.getElementById('number1').checked) {
document.write("<h1>Hello" +
"member</h1>");
}
</script>

IMHO, using list() and dict() makes your Python look like C. Ugh.

As help to anybody that had the same problem as me, I accidentally mistyped the implementation type instead of the interface e.g.

var mockFileBrowser = new Mock<FileBrowser>();

instead of

var mockFileBrowser = new Mock<IFileBrowser>();

The answer is neither.

Docker Compose (herein referred to as compose) will use the Dockerfile if you add the build command to your project's docker-compose.yml.

Your Docker workflow should be to build a suitable Dockerfile for each image you wish to create, then use compose to assemble the images using the build command.

You can specify the path to your individual Dockerfiles using build /path/to/dockerfiles/blah where /path/to/dockerfiles/blah is where blah's Dockerfile lives.

Here's a version using the excellent requests library:

from requests import session

payload = {
    'action': 'login',
    'username': USERNAME,
    'password': PASSWORD
}

with session() as c:
    c.post('http://example.com/login.php', data=payload)
    response = c.get('http://example.com/protected_page.php')
    print(response.headers)
    print(response.text)

To install Protocol Buffer (as of today version v3.7.0)

1. Go to this website

2. download the zip file according to your OS (e.g.: protoc-3.7.0-osx-x86_64.zip). This applies also to other OS.

3. Move the executable in protoc-3/bin/protoc to one of your directories in PATH. In Mac I suggest to put it into /usr/local/bin

Now your good to go

(optional) There is also an include file, you can add. This is a snippet of the README.md

If you intend to use the included well known types then don't forget to
copy the contents of the 'include' directory somewhere as well, for example
into '/usr/local/include/'.

Please refer to our official github site for more installation instructions:
https://github.com/protocolbuffers/protobuf

This is an O(n) solution.

mydict   = {}
cnt, itm = 0, ''
for item in reversed(lst):
     mydict[item] = mydict.get(item, 0) + 1
     if mydict[item] >= cnt :
         cnt, itm = mydict[item], item

print itm

(reversed is used to make sure that it returns the lowest index item)

This page has some references for all of the specified datetime conversions available to the CONVERT function. If your values don't fall into one of the acceptable patterns, then I think the best thing is to go the ParseExact route.

sys.exc_info() returns a tuple with three values (type, value, traceback).

1. Here type gets the exception type of the Exception being handled
2. value is the arguments that are being passed to constructor of exception class
3. traceback contains the stack information like where the exception occurred etc.

For Example, In the following program

try:

    a = 1/0

except Exception,e:

    exc_tuple = sys.exc_info()

Now If we print the tuple the values will be this.

1. exc_tuple[0] value will be "ZeroDivisionError"
2. exc_tuple[1] value will be "integer division or modulo by zero" (String passed as parameter to the exception class)
3. exc_tuple[2] value will be "trackback object at (some memory address)"

The above details can also be fetched by simply printing the exception in string format.

print str(e)

The line in your controller code, which reads $scope.myFunc={ should be $scope.myFunc = function() { the function() part is important to indicate, it is a function!

The updated controller code would be

app.controller('myCtrl',['$scope',function($cope){
    $scope.myFunc = function() {
    console.log("function called");
  };
}]);

del list[:] 

Will delete the values of that list variable

del list

Will delete the variable itself from memory

I think this is the easy way example to iterate item.

declare @cateid int
select CateID into [#TempTable] from Category where GroupID = 'STOCKLIST'

while (select count(*) from #TempTable) > 0
begin
    select top 1 @cateid = CateID from #TempTable
    print(@cateid)

    --DO SOMETHING HERE

    delete #TempTable where CateID = @cateid
end

drop table #TempTable

PHP can be easily utilized for reading bar codes printed on paper documents. Connecting manual barcode reader to the computer via USB significantly extends usability of PHP (or any other web programming language) into tasks involving document and product management, like finding a book records in the database or listing all bills for a particular customer.

Following sections briefly describe process of connecting and using manual bar code reader with PHP.

The usage of bar code scanners described in this article are in the same way applicable to any web programming language, such as ASP, Python or Perl. This article uses only PHP since all tests have been done with PHP applications.

What is a bar code reader (scanner)

Bar code reader is a hardware pluggable into computer that sends decoded bar code strings into computer. The trick is to know how to catch that received string. With PHP (and any other web programming language) the string will be placed into focused input HTML element in browser. Thus to catch received bar code string, following must be done:

just before reading the bar code, proper input element, such as INPUT TEXT FIELD must be focused (mouse cursor is inside of the input field). once focused, start reading the code when the code is recognized (bar code reader usually shortly beeps), it is send to the focused input field. By default, most of bar code readers will append extra special character to decoded bar code string called CRLF (ENTER). For example, if decoded bar code is "12345AB", then computer will receive "12345ABENTER". Appended character ENTER (or CRLF) emulates pressing the key ENTER causing instant submission of the HTML form:

<form action="search.php" method="post">
    <input name="documentID" onmouseover="this.focus();" type="text">
</form>

Choosing the right bar code scanner

When choosing bar code reader, one should consider what types of bar codes will be read with it. Some bar codes allow only numbers, others will not have checksum, some bar codes are difficult to print with inkjet printers, some barcode readers have narrow reading pane and cannot read for example barcodes with length over 10 cm. Most of barcode readers support common barcodes, such as EAN8, EAN13, CODE 39, Interleaved 2/5, Code 128 etc.

For office purposes, the most suitable barcodes seem to be those supporting full range of alphanumeric characters, which might be:

• code 39 - supports 0-9, uppercased A-Z, and few special characters (dash, comma, space, $, /, +, %, *)
• code 128 - supports 0-9, a-z, A-Z and other extended characters

Other important things to note:

• make sure all standard barcodes are supported, at least CODE39, CODE128, Interleaved25, EAN8, EAN13, PDF417, QRCODE.
• use only standard USB plugin cables. RS232 interfaces are meant for industrial usage, rather than connecting to single PC.
• the cable should be long enough, at least 1.5 m - the longer the better.
• bar code reader plugged into computer should not require other power supply - it should power up simply by connecting to PC via USB.
• if you also need to print bar code into generated PDF documents, you can use TCPDF open source library that supports most of common 2D bar codes.

Installing scanner drivers

Installing manual bar code reader requires installing drivers for your particular operating system and should be normally supplied with purchased bar code reader.

Once installed and ready, bar code reader turns on signal LED light. Reading the barcode starts with pressing button for reading.

Scanning the barcode - how does it work?

STEP 1 - Focused input field ready for receiving character stream from bar code scanner:

STEP 2 - Received barcode string from bar code scanner is immediatelly submitted for search into database, which creates nice "automated" effect:

STEP 3 - Results returned after searching the database with submitted bar code:

Conclusion

It seems, that utilization of PHP (and actually any web programming language) for scanning the bar codes has been quite overlooked so far. However, with natural support of emulated keypress (ENTER/CRLF) it is very easy to automate collecting & processing recognized bar code strings via simple HTML (GUI) fomular.

The key is to understand, that recognized bar code string is instantly sent to the focused HTML element, such as INPUT text field with appended trailing character ASCII 13 (=ENTER/CRLF, configurable option), which instantly sends input text field with populated received barcode as a HTML formular to any other script for further processing.

Hope this helps you :)

console.log("my object: %o", myObj)

Otherwise you'll end up with a string representation sometimes displaying:

[object Object]

or some such.

The simplest way is to do

line.Replace(@",", @";");

Output is shown as below:

If you are working with character variables (note that stringsAsFactors is false here) you can use replace:

junk <- data.frame(x <- rep(LETTERS[1:4], 3), y <- letters[1:12], stringsAsFactors = FALSE)
colnames(junk) <- c("nm", "val")

junk$nm <- replace(junk$nm, junk$nm == "B", "b")
junk
#    nm val
# 1   A   a
# 2   b   b
# 3   C   c
# 4   D   d
# ...

There's no way to specify a StringComparer at the point where you try to get a value. If you think about it, "foo".GetHashCode() and "FOO".GetHashCode() are totally different so there's no reasonable way you could implement a case-insensitive get on a case-sensitive hash map.

You can, however, create a case-insensitive dictionary in the first place using:-

var comparer = StringComparer.OrdinalIgnoreCase;
var caseInsensitiveDictionary = new Dictionary<string, int>(comparer);

Or create a new case-insensitive dictionary with the contents of an existing case-sensitive dictionary (if you're sure there are no case collisions):-

var oldDictionary = ...;
var comparer = StringComparer.OrdinalIgnoreCase;
var newDictionary = new Dictionary<string, int>(oldDictionary, comparer);

This new dictionary then uses the GetHashCode() implementation on StringComparer.OrdinalIgnoreCase so comparer.GetHashCode("foo") and comparer.GetHashcode("FOO") give you the same value.

Alternately, if there are only a few elements in the dictionary, and/or you only need to lookup once or twice, you can treat the original dictionary as an IEnumerable<KeyValuePair<TKey, TValue>> and just iterate over it:-

var myKey = ...;
var myDictionary = ...;
var comparer = StringComparer.OrdinalIgnoreCase;
var value = myDictionary.FirstOrDefault(x => String.Equals(x.Key, myKey, comparer)).Value;

Or if you prefer, without the LINQ:-

var myKey = ...;
var myDictionary = ...;
var comparer = StringComparer.OrdinalIgnoreCase;
int? value;
foreach (var element in myDictionary)
{
  if (String.Equals(element.Key, myKey, comparer))
  {
    value = element.Value;
    break;
  }
}

This saves you the cost of creating a new data structure, but in return the cost of a lookup is O(n) instead of O(1).

This is a much less professional and much more expensive way but it should be easier to understand and more helpful for beginners.

public static float roundFloat(float F, int roundTo){

    String num = "#########.";

    for (int count = 0; count < roundTo; count++){
        num += "0";
    }

    DecimalFormat df = new DecimalFormat(num);

    df.setRoundingMode(RoundingMode.HALF_UP);

    String S = df.format(F);
    F = Float.parseFloat(S);

    return F;
}

You could do it if template is a react component.

Template.js

var React = require('react');

var Template = React.createClass({
    render: function(){
        return (<div>Mi HTML</div>);
    }
});

module.exports = Template;

MainComponent.js

var React = require('react');
var ReactDOM = require('react-dom');
var injectTapEventPlugin = require("react-tap-event-plugin");
var Template = require('./Template');

//Needed for React Developer Tools
window.React = React;

//Needed for onTouchTap
//Can go away when react 1.0 release
//Check this repo:
//https://github.com/zilverline/react-tap-event-plugin
injectTapEventPlugin();

var MainComponent = React.createClass({
    render: function() {
        return(
            <Template/>
        );
    }
});

// Render the main app react component into the app div.
// For more details see: https://facebook.github.io/react/docs/top-level-api.html#react.render
ReactDOM.render(
  <MainComponent />,
  document.getElementById('app')
 );

And if you are using Material-UI, for compatibility use Material-UI Components, no normal inputs.

I am using microsoft's Android emulator with Android Studio. I have an AMD FX8350. The ARM one in android studio is terribly slow.

The only issue is that it requires Hyper-V which is not available on windows 10 Home.

Its a really quick emulator and it is free. The best emulator I have used.

I would like to add yourkit java and .net profiler, I love it for Java, haven't tried .NET version though.

Store all the to be deleted ID's into a table. Then there are 3 ways. 1) loop through all the ID's in the table, then delete one row at a time for X commit interval. X can be a 100 or 1000. It works on OLTP environment and you can control the locks.

2) Use Oracle Bulk Delete

3) Use correlated delete query.

Single query is usually faster than multiple queries because of less context switching, and possibly less parsing.

Just to add some additional info to demonstrate how much difference the member initialization list can mak. In the leetcode 303 Range Sum Query - Immutable, https://leetcode.com/problems/range-sum-query-immutable/, where you need to construct and initialize to zero a vector with certain size. Here is two different implementation and speed comparison.

Without member initialization list, to get AC it cost me about 212 ms.

class NumArray {
public:
vector<int> preSum;
NumArray(vector<int> nums) {
    preSum = vector<int>(nums.size()+1, 0);
    int ps = 0;
    for (int i = 0; i < nums.size(); i++)
    {
        ps += nums[i];
        preSum[i+1] = ps;
    }
}

int sumRange(int i, int j) {
    return preSum[j+1] - preSum[i];
}
};

Now using member initialization list, the time to get AC is about 108 ms. With this simple example, it is quite obvious that, member initialization list is way more efficient. All the measurement is from the running time from LC.

class NumArray {
public:
vector<int> preSum;
NumArray(vector<int> nums) : preSum(nums.size()+1, 0) { 
    int ps = 0;
    for (int i = 0; i < nums.size(); i++)
    {
        ps += nums[i];
        preSum[i+1] = ps;
    }
}

int sumRange(int i, int j) {
    return preSum[j+1] - preSum[i];
}
};

A fixed point number just means that there are a fixed number of digits after the decimal point. A floating point number allows for a varying number of digits after the decimal point.

For example, if you have a way of storing numbers that requires exactly four digits after the decimal point, then it is fixed point. Without that restriction it is floating point.

Often, when fixed point is used, the programmer actually uses an integer and then makes the assumption that some of the digits are beyond the decimal point. For example, I might want to keep two digits of precision, so a value of 100 means actually means 1.00, 101 means 1.01, 12345 means 123.45, etc.

Floating point numbers are more general purpose because they can represent very small or very large numbers in the same way, but there is a small penalty in having to have extra storage for where the decimal place goes.

update: sorry misunderstood the question, removed .has() answer.

another alternative way, create .hasId() plugin

// the plugin_x000D_
$.fn.hasId = function(id) {_x000D_
  return this.attr('id') == id;_x000D_
};_x000D_
_x000D_
// select first class_x000D_
$('.mydiv').hasId('foo') ?_x000D_
  console.log('yes') : console.log('no');_x000D_
_x000D_
// select second class_x000D_
// $('.mydiv').eq(1).hasId('foo')_x000D_
// or_x000D_
$('.mydiv:eq(1)').hasId('foo') ?_x000D_
  console.log('yes') : console.log('no');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
<div class="mydiv" id="foo"></div>_x000D_
<div class="mydiv"></div>

To answer your question in one sentence:

Per default, Maps don't have a last entry, it's not part of their contract.

And a side note: it's good practice to code against interfaces, not the implementation classes (see Effective Java by Joshua Bloch, Chapter 8, Item 52: Refer to objects by their interfaces).

So your declaration should read:

Map<String,Integer> map = new HashMap<String,Integer>();

(All maps share a common contract, so the client need not know what kind of map it is, unless he specifies a sub interface with an extended contract).

Possible Solutions

Sorted Maps:

There is a sub interface SortedMap that extends the map interface with order-based lookup methods and it has a sub interface NavigableMap that extends it even further. The standard implementation of this interface, TreeMap, allows you to sort entries either by natural ordering (if they implement the Comparable interface) or by a supplied Comparator.

You can access the last entry through the lastEntry method:

NavigableMap<String,Integer> map = new TreeMap<String, Integer>();
// add some entries
Entry<String, Integer> lastEntry = map.lastEntry();

Linked maps:

There is also the special case of LinkedHashMap, a HashMap implementation that stores the order in which keys are inserted. There is however no interface to back up this functionality, nor is there a direct way to access the last key. You can only do it through tricks such as using a List in between:

Map<String,String> map = new LinkedHashMap<String, Integer>();
// add some entries
List<Entry<String,Integer>> entryList =
    new ArrayList<Map.Entry<String, Integer>>(map.entrySet());
Entry<String, Integer> lastEntry =
    entryList.get(entryList.size()-1);

Proper Solution:

Since you don't control the insertion order, you should go with the NavigableMap interface, i.e. you would write a comparator that positions the Not-Specified entry last.

Here is an example:

final NavigableMap<String,Integer> map = 
        new TreeMap<String, Integer>(new Comparator<String>() {
    public int compare(final String o1, final String o2) {
        int result;
        if("Not-Specified".equals(o1)) {
            result=1;
        } else if("Not-Specified".equals(o2)) {
            result=-1;
        } else {
            result =o1.compareTo(o2);
        }
        return result;
    }

});
map.put("test", Integer.valueOf(2));
map.put("Not-Specified", Integer.valueOf(1));
map.put("testtest", Integer.valueOf(3));
final Entry<String, Integer> lastEntry = map.lastEntry();
System.out.println("Last key: "+lastEntry.getKey()
         + ", last value: "+lastEntry.getValue());

Output:

Last key: Not-Specified, last value: 1

Solution using HashMap:

If you must rely on HashMaps, there is still a solution, using a) a modified version of the above comparator, b) a List initialized with the Map's entrySet and c) the Collections.sort() helper method:

    final Map<String, Integer> map = new HashMap<String, Integer>();
    map.put("test", Integer.valueOf(2));
    map.put("Not-Specified", Integer.valueOf(1));
    map.put("testtest", Integer.valueOf(3));

    final List<Entry<String, Integer>> entries =
        new ArrayList<Entry<String, Integer>>(map.entrySet());
    Collections.sort(entries, new Comparator<Entry<String, Integer>>(){

        public int compareKeys(final String o1, final String o2){
            int result;
            if("Not-Specified".equals(o1)){
                result = 1;
            } else if("Not-Specified".equals(o2)){
                result = -1;
            } else{
                result = o1.compareTo(o2);
            }
            return result;
        }

        @Override
        public int compare(final Entry<String, Integer> o1,
            final Entry<String, Integer> o2){
            return this.compareKeys(o1.getKey(), o2.getKey());
        }

    });

    final Entry<String, Integer> lastEntry =
        entries.get(entries.size() - 1);
    System.out.println("Last key: " + lastEntry.getKey() + ", last value: "
        + lastEntry.getValue());

}

Output:

Last key: Not-Specified, last value: 1

To make an exact copy, permissions, ownership, and all use "-a" with "cp". "-r" will copy the contents of the files but not necessarily keep other things the same.

cp -av Source/* Dest/

(make sure Dest/ exists first)

If you want to repeatedly update from one to the other or make sure you also copy all dotfiles, rsync is a great help:

rsync -av --delete Source/ Dest/

This is also "recoverable" in that you can restart it if you abort it while copying. I like "-v" because it lets you watch what is going on but you can omit it.

NewScores is an alias to Scores table - it looks like you can combine the queries as follows:

SELECT 
    ROW_NUMBER() OVER( ORDER BY NETT) AS Rank, 
    Name, 
    FlagImg, 
    Nett, 
    Rounds 
FROM (
    SELECT 
        Members.FirstName + ' ' + Members.LastName AS Name, 
        CASE 
            WHEN MenuCountry.ImgURL IS NULL THEN 
                '~/images/flags/ismygolf.png' 
            ELSE 
                MenuCountry.ImgURL 
        END AS FlagImg, 
        AVG(CAST(NewScores.NetScore AS DECIMAL(18, 4))) AS Nett, 
        COUNT(Score.ScoreID) AS Rounds 
    FROM 
        Members 
        INNER JOIN 
        Score NewScores
            ON Members.MemberID = NewScores.MemberID 
        LEFT OUTER JOIN MenuCountry 
            ON Members.Country = MenuCountry.ID 
    WHERE 
        Members.Status = 1 
        AND NewScores.InsertedDate >= DATEADD(mm, -3, GETDATE())
    GROUP BY 
        Members.FirstName + ' ' + Members.LastName, 
        MenuCountry.ImgURL
    ) AS Dertbl 
ORDER BY;

Your problem is that you have to change:

printf("%"); 

to

printf("%%");

Or you could use ASCII code and write:

printf("%c", 37);

:)

You should style for ::-ms-clear (http://msdn.microsoft.com/en-us/library/windows/apps/hh465740.aspx):

::-ms-clear {
   display: none;
}

And you also style for ::-ms-reveal pseudo-element for password field:

::-ms-reveal {
   display: none;
}

When you want to run an executable file from the Command prompt, (cmd.exe), or a batch file, it will:

• Search the current working directory for the executable file.
• Search all locations specified in the %PATH% environment variable for the executable file.

If the file isn't found in either of those options you will need to either:

1. Specify the location of your executable.
2. Change the working directory to that which holds the executable.
3. Add the location to %PATH% by apending it, (recommended only with extreme caution).

You can see which locations are specified in %PATH% from the Command prompt, Echo %Path%.

Because of your reported error we can assume that Mobile.exe is not in the current directory or in a location specified within the %Path% variable, so you need to use 1., 2. or 3..

Examples for 1.

C:\directory_path_without_spaces\My-App\Mobile.exe

or:

"C:\directory path with spaces\My-App\Mobile.exe"

Alternatively you may try:

Start C:\directory_path_without_spaces\My-App\Mobile.exe

or

Start "" "C:\directory path with spaces\My-App\Mobile.exe"

Where "" is an empty title, (you can optionally add a string between those doublequotes).

Examples for 2.

CD /D C:\directory_path_without_spaces\My-App
Mobile.exe

or

CD /D "C:\directory path with spaces\My-App"
Mobile.exe

You could also use the /D option with Start to change the working directory for the executable to be run by the start command

Start /D C:\directory_path_without_spaces\My-App Mobile.exe

or

Start "" /D "C:\directory path with spaces\My-App" Mobile.exe

string = "firstName:name1, lastName:last1";

This will work:

var fields = string.split(', '),
    fieldObject = {};

if( typeof fields === 'object') ){
   fields.each(function(field) {
      var c = property.split(':');
      fieldObject[c[0]] = c[1];
   });
}

However it's not efficient. What happens when you have something like this:

string = "firstName:name1, lastName:last1, profileUrl:http://localhost/site/profile/1";

split() will split 'http'. So i suggest you use a special delimiter like pipe

 string = "firstName|name1, lastName|last1";


   var fields = string.split(', '),
        fieldObject = {};

    if( typeof fields === 'object') ){
       fields.each(function(field) {
          var c = property.split('|');
          fieldObject[c[0]] = c[1];
       });
    }

Doing this asynchronously is quite easy. It's particularly useful if you're concerned for blocking the thread (likely).

const fs = require('fs');
const fileName = './file.json';
const file = require(fileName);
    
file.key = "new value";
    
fs.writeFile(fileName, JSON.stringify(file), function writeJSON(err) {
  if (err) return console.log(err);
  console.log(JSON.stringify(file));
  console.log('writing to ' + fileName);
});

The caveat is that json is written to the file on one line and not prettified. ex:

{
  "key": "value"
}

will be...

{"key": "value"}

To avoid this, simply add these two extra arguments to JSON.stringify

JSON.stringify(file, null, 2)

null - represents the replacer function. (in this case we don't want to alter the process)

2 - represents the spaces to indent.

Your logic in reading

For all built-in Python objects (like strings, lists, dicts, functions, etc.), if x is y, then x==y is also True.

is slightly flawed.

If is applies then == will be True, but it does NOT apply in reverse. == may yield True while is yields False.

You can choose any extension in the world if you setup Apache correctly. You could use .html to do PHP if you set up in your Apache config.

In conclusion, extension has nothing to do with the app or website itself. You can use the one you want, but normaly, use .php (to not reinvent the wheel)

But in 2019, you should use routing and forgot about extension at the end.

I recommend you using Laravel.

In answer to @KingCrunch: True, Apache not use it by default but you can easily use it if you change config. But this it not recommended since everybody know that it not really an option.

I already saw .html files that executed PHP using the html extension.

Use its value directly:

In [79]: df[df.c > 0.5][['b', 'e']].values
Out[79]: 
array([[ 0.98836259,  0.82403141],
       [ 0.337358  ,  0.02054435],
       [ 0.29271728,  0.37813099],
       [ 0.70033513,  0.69919695]])

For example, you can invoke a private constructor inside a friend class or a friend function.

Singleton pattern usually uses it to make sure that nobody creates more instances of the intended type.

I solve this by adding code into manifest:

<activity android:name=".Login"
        android:fitsSystemWindows="true"
        android:windowSoftInputMode="stateHidden|adjustPan"
</activity>

AJAX requests are no different from GET and POST requests initiated through a <form> element. Which means you can use $_GET and $_POST to retrieve the data.

When you're making an AJAX request (jQuery example):

// JavaScript file

elements = [1, 2, 9, 15].join(',')
$.post('/test.php', {elements: elements})

It's (almost) equivalent to posting this form:

<form action="/test.php" method="post">
  <input type="text" name="elements" value="1,2,9,15">
</form>

In both cases, on the server side you can read the data from the $_POST variable:

// test.php file

$elements = $_POST['elements'];
$elements = explode(',', $elements);

For the sake of simplicity I'm joining the elements with comma here. JSON serialization is a more universal solution, though.

This work for me:

cache:clear --env=prod

Most likely the node_modules folder became Read Only. You can try updating folder permissions but if you do not have admin access, the npm install --force will work.
