Programs & Examples On #Return by reference

You can only return non-local objects by reference. The destructor may have invalidated some internal pointer, or whatever.

Don't be afraid of returning values -- it's fast!

For people who have narrowed down the issue to the COMMENT ON statements (as per various answers below) and who have superuser access to the source database from which the dump file is created, the simplest solution might be to prevent the comments from being included to the dump file in the first place, by removing them from the source database being dumped...

COMMENT ON EXTENSION postgis IS NULL;
COMMENT ON EXTENSION plpgsql IS NULL;
COMMENT ON SCHEMA public IS NULL;

Future dumps then won't include the COMMENT ON statements.

For this issue need to add the partition for date column values, If last partition 20201231245959, then inserting the 20210110245959 values, this issue will occurs.

For that need to add the 2021 partition into that table

ALTER TABLE TABLE_NAME ADD PARTITION PARTITION_NAME VALUES LESS THAN (TO_DATE('2021-12-31 24:59:59', 'SYYYY-MM-DD HH24:MI:SS', 'NLS_CALENDAR=GREGORIAN')) NOCOMPRESS

If you have lodash you can use its .get method

_.get(a, 'b.c.d.e')

or give it a default value

_.get(a, 'b.c.d.e', default)

You can't do what I think you're asking to do.

The only privileges you can grant on procedures are EXECUTE and DEBUG.

If you want to allow user B to create a procedure in user A schema, then user B must have the CREATE ANY PROCEDURE privilege. ALTER ANY PROCEDURE and DROP ANY PROCEDURE are the other applicable privileges required to alter or drop user A procedures for user B. All are wide ranging privileges, as it doesn't restrict user B to any particular schema. User B should be highly trusted if granted these privileges.

EDIT:

As Justin mentioned, the way to give execution rights to A for a procedure owned by B:

GRANT EXECUTE ON b.procedure_name TO a;

What seems easy is actually tricky if you want to be completely compatible.

var e = document.createElement('div');

Let's say you have an id of 'div1' to add.

e['id'] = 'div1';
e.id = 'div1';
e.attributes['id'] = 'div1';
e.createAttribute('id','div1')

But there are contingencies, of course. Will not work in IE prior to 8:e.attributes['style'] Will not error but won't actually set the class, it must be className:e['class'] .
However, if you're using attributes then this WILL work:e.attributes['class']

In summary, think of attributes as literal and object-oriented.

In literal, you just want it to spit out x='y' and not think about it. This is what attributes, setAttribute, createAttribute is for (except for IE's style exception). But because these are really objects things can get confused.

Since you are going to the trouble of properly creating a DOM element instead of jQuery innerHTML slop, I would treat it like one and stick with the e.className = 'fooClass' and e.id = 'fooID'. This is a design preference, but in this instance trying to treat is as anything other than an object works against you.

It will never backfire on you like the other methods might, just be aware of class being className and style being an object so it's style.width not style="width:50px". Also remember tagName but this is already set by createElement so you shouldn't need to worry about it.

This was longer than I wanted, but CSS manipulation in JS is tricky business.

To finish the set off (with what has already been suggested):

SELECT * FROM sys.views

This gives extra properties on each view, not available from sys.objects (which contains properties common to all types of object) or INFORMATION_SCHEMA.VIEWS. Though INFORMATION_SCHEMA approach does provide the view definition out-of-the-box.

This Worked for me:

$ sudo easy_install pip
$ sudo easy_install --upgrade six
$ export TF_BINARY_URL=https://storage.googleapis.com/tensorflow/mac/tensorflow-0.9.0-py2-none-any.whl
$ sudo pip install --upgrade $TF_BINARY_URL

here is a version that handles multiple requests, also checks for cancelled status in callback to suppress errors in error block. (in Typescript)

controller level:

    requests = new Map<string, ng.IDeferred<{}>>();

in my http get:

    getSomething(): void {
        let url = '/api/someaction';
        this.cancel(url); // cancel if this url is in progress

        var req = this.$q.defer();
        this.requests.set(url, req);
        let config: ng.IRequestShortcutConfig = {
            params: { id: someId}
            , timeout: req.promise   // <--- promise to trigger cancellation
        };

        this.$http.post(url, this.getPayload(), config).then(
            promiseValue => this.updateEditor(promiseValue.data as IEditor),
            reason => {
                // if legitimate exception, show error in UI
                if (!this.isCancelled(req)) {
                    this.showError(url, reason)
                }
            },
        ).finally(() => { });
    }

helper methods

    cancel(url: string) {
        this.requests.forEach((req,key) => {
            if (key == url)
                req.resolve('cancelled');
        });
        this.requests.delete(url);
    }

    isCancelled(req: ng.IDeferred<{}>) {
        var p = req.promise as any; // as any because typings are missing $$state
        return p.$$state && p.$$state.value == 'cancelled';
    }

now looking at the network tab, i see that it works beatuifully. i called the method 4 times and only the last one went through.

Reading all the comments by you, I think you are just trying to display it in a certain format rather than changing the value / casting it to int.

I think the easiest way to display 12.00 as "12" would be using string format specifiers.

double val = 12.00;

string displayed_value = val.ToString("N0"); // Output will be "12"

The best part about this solution is, that it will change 1200.00 to "1,200" (add a comma to it) which is very useful to display amount/money/price of something.

More information can be found here: https://msdn.microsoft.com/en-us/library/kfsatb94(v=vs.110).aspx

... and the uppercase is:

"Awesome String".upcase
=> "AWESOME STRING"

The only way to get the iOS dictation is to sign up yourself through Nuance: http://dragonmobile.nuancemobiledeveloper.com/ - it's expensive, because it's the best. Presumably, Apple's contract prevents them from exposing an API.

The built in iOS accessibility features allow immobilized users to access dictation (and other keyboard buttons) through tools like VoiceOver and Assistive Touch. It may not be worth reinventing this if your users might be familiar with these tools.

Just Remove the "Target Framework 4.0" and close the bracket.

It will Work

Comma separate the values:

UPDATE settings SET postsPerPage = $postsPerPage, style = $style WHERE id = '1'"

For .NET 4.0 and later,

var files = Directory.EnumerateFiles("C:\\path", "*.*", SearchOption.AllDirectories)
            .Where(s => s.EndsWith(".mp3") || s.EndsWith(".jpg"));

For earlier versions of .NET,

var files = Directory.GetFiles("C:\\path", "*.*", SearchOption.AllDirectories)
            .Where(s => s.EndsWith(".mp3") || s.EndsWith(".jpg"));

edit: Please read the comments. The improvement that Paul Farry suggests, and the memory/performance issue that Christian.K points out are both very important.

I faced this problem today and resolved it by checking the mapping class. I had a class which had 5 properties to which 5 columns returned from stored procedure were being mapped. Those properties were non-nullable and due to which i was getting the error. I made them nullable and the issue resolved.

    public int? Pause { get; set; }
    public int? Delay { get; set; }
    public int? Transition { get; set; }
    public int? TransitionTime { get; set; }
    public int? TransitionResolution { get; set; }

Added "?" with data type to made them nullable.

Secondly i also added isNull check in the stored procedure as well as follows:

    isnull(co_pivot.Pause, 0) as Pause,
    isnull(co_pivot.Delay, 0) as Delay,
    isnull(co_pivot.Transition, 0) as Transition,
    isnull(co_pivot.TransitionTime, 0) as TransitionTime,
    isnull(co_pivot.TransitionResolution, 0) as TransitionResolution

Hope this helps someone.

1. You can remove brackets and line breaks.

if (city.getName() != null) name = city.getName(); else name = "N/A";

2. You can use ?: operators in java.

Syntax:

Variable = Condition ? BlockTrue : BlockElse;

So in your code you can do like this:

name = city.getName() == null ? "N/A" : city.getName();

3. Assign condition result for Boolean

boolean hasName = city.getName() != null;

EXTRA: for curious

In some languages based in JAVA like Groovy, you can use this syntax:

name = city.getName() ?: "N/A";

The operator ?: assign the value returned from the variable which we are asking for. In this case, the value of city.getName() if it's not null.

In case that you run test in sqlite run

sudo apt install sqlite3 && sudo apt install php-sqlite3

If you run test in window, you dont need install nothing. Only config your phpunit.xml

If the line before your error contains COMMENT '' either populate the comment in the script or remove the empty comment definition. I've found this in scripts generated by MySQL Workbench.

Use the Chart Wizard.

On Step 2 of 4, there is a tab labeled "Series". There are 3 fields and a list box on this tab. The list box shows the different series you are already including on the chart. Each series has both a "Name" field and a "Values" field that is specific to that series. The final field is the "Category (X) axis labels" field, which is common to all series.

Click on the "Add" button below the list box. This will add a blank series to your list box. Notice that the values for "Name" and for "Values" change when you highlight a series in the list box.

Select your new series.

There is an icon in each field on the right side. This icon allows you to select cells in the workbook to pull the data from. When you click it, the Wizard temporarily hides itself (except for the field you are working in) allowing you to interact with the workbook.

Select the appropriate sheet in the workbook and then select the fields with the data you want to show in the chart. The button on the right of the field can be clicked to unhide the wizard.

Hope that helps.

EDIT: The above applies to 2003 and before. For 2007, when the chart is selected, you should be able to do a similar action using the "Select Data" option on the "Design" tab of the ribbon. This opens up a dialog box listing the Series for the chart. You can select the series just as you could in Excel 2003, but you must use the "Add" and "Edit" buttons to define custom series.

I will try to answer using practical scenario to show the distinction between the two.

Interfaces come with zero payload i.e. no state has to be maintained and thus are better choice to just associate a contract (capability) with a class.

For example, say I have a Task class that performs some action, now to execute a task in separate thread I don't really need to extend Thread class rather better choice is to make Task implement Runnable interface (i.e. implement its run() method) and then pass object of this Task class to a Thread instance and call its start() method.

Now you can ask what if Runnable was a abstract class?

Well technically that was possible but design wise that would have been a poor choice reason being:

• Runnable has no state associated with it and neither it 'offers' any default implementation for the run() method
• Task would have to extend it thus it couldn't extend any other class
• Task has nothing to offer as specialization to Runnable class, all it needs is to override run() method

In other words, Task class needed a capability to be run in a thread which it achieved by implementing Runnable interface verses extending the Thread class that would make it a thread.

Simply put us interface to define a capability (contract), while use a abstract class to define skeleton (common/partial) implementation of it.

Disclaimer: silly example follows, try not to judge :-P

interface Forgiver {
    void forgive();
}

abstract class GodLike implements Forgiver {
    abstract void forget();
    final void forgive() {
        forget();
    }
}

Now you have been given a choice to be GodLike but you may choose to be Forgiver only (i.e. not GodLike) and do:

class HumanLike implements Forgiver {
    void forgive() {
       // forgive but remember    
    }
}

Or you may may choose to be GodLike and do:

class AngelLike extends GodLike {
    void forget() {
       // forget to forgive     
    }
}

P.S. with java 8 interface can also have static as well default (overridable implementation) methods and thus difference b/w interface and abstract class is even more narrowed down.

def fruitBag = ["orange","banana","coconut"]
def fruit = fruitBag.collect{item -> item.contains('n')}

I did it like this so it works if someone is looking for it.

Wait and await - while similar conceptually - are actually completely different.

Wait will synchronously block until the task completes. So the current thread is literally blocked waiting for the task to complete. As a general rule, you should use "async all the way down"; that is, don't block on async code. On my blog, I go into the details of how blocking in asynchronous code causes deadlock.

await will asynchronously wait until the task completes. This means the current method is "paused" (its state is captured) and the method returns an incomplete task to its caller. Later, when the await expression completes, the remainder of the method is scheduled as a continuation.

You also mentioned a "cooperative block", by which I assume you mean a task that you're Waiting on may execute on the waiting thread. There are situations where this can happen, but it's an optimization. There are many situations where it can't happen, like if the task is for another scheduler, or if it's already started or if it's a non-code task (such as in your code example: Wait cannot execute the Delay task inline because there's no code for it).

You may find my async / await intro helpful.

If you can go the functional way, the following is pretty clear

new_list = [x] + your_list

Of course you haven't inserted x into your_list, rather you have created a new list with x preprended to it.

Here is what made the error disappear for me:

Close eclipse, open up a terminal window and run:

$ mvn clean eclipse:clean eclipse:eclipse

Are you using Maven? If so,

1. Right-click on the project, Build Path and go to Configure Build Path
2. Click the libraries tab. If Maven dependencies are not in the list, you need to add it.
3. Close the dialog.

To add it: Right-click on the project, Maven → Disable Maven Nature Right-click on the project, Configure → Convert to Maven Project.

And then clean

Edit 1:

If that doesn't resolve the issue try right-clicking on your project and select properties. Select Java Build Path → Library tab. Look for a JVM. If it's not there, click to add Library and add the default JVM. If VM is there, click edit and select the default JVM. Hopefully, that works.

Edit 2:

You can also try going into the folder where you have all your projects and delete the .metadata for eclipse (be aware that you'll have to re-import all the projects afterwards! Also all the environment settings you've set would also have to be redone). After it was deleted just import the project again, and hopefully, it works.

The problem with every other answer in this thread is that none of them properly parse all special cases of the strings within the enum.

The biggest special case character that was throwing me for a loop was single quotes, as they are encoded themselves as 2 single quotes together! So, for example, an enum with the value 'a' is encoded as enum('''a'''). Horrible, right?

Well, the solution is to use MySQL to parse the data for you!

Since everyone else is using PHP in this thread, that is what I will use. Following is the full code. I will explain it after. The parameter $FullEnumString will hold the entire enum string, extracted from whatever method you want to use from all the other answers. RunQuery() and FetchRow() (non associative) are stand ins for your favorite DB access methods.

function GetDataFromEnum($FullEnumString)
{
    if(!preg_match('/^enum\((.*)\)$/iD', $FullEnumString, $Matches))
        return null;
    return FetchRow(RunQuery('SELECT '.$Matches[1]));
}

preg_match('/^enum\((.*)\)$/iD', $FullEnumString, $Matches) confirms that the enum value matches what we expect, which is to say, "enum(".$STUFF.")" (with nothing before or after). If the preg_match fails, NULL is returned.

This preg_match also stores the list of strings, escaped in weird SQL syntax, in $Matches[1]. So next, we want to be able to get the real data out of that. So you just run "SELECT ".$Matches[1], and you have a full list of the strings in your first record!

So just pull out that record with a FetchRow(RunQuery(...)) and you’re done.

If you wanted to do this entire thing in SQL, you could use the following

SET @TableName='your_table_name', @ColName='your_col_name';
SET @Q=(SELECT CONCAT('SELECT ', (SELECT SUBSTR(COLUMN_TYPE, 6, LENGTH(COLUMN_TYPE)-6) FROM information_schema.COLUMNS WHERE TABLE_NAME=@TableName AND COLUMN_NAME=@ColName)));
PREPARE stmt FROM @Q;
EXECUTE stmt;

P.S. To preempt anyone from saying something about it, no, I do not believe this method can lead to SQL injection.

Most of the solutions consider that the lists do not have duplicates. In case your lists do have duplicates you can try this:

def isSubList(subList,mlist):
    uniqueElements=set(subList)
    for e in uniqueElements:
        if subList.count(e) > mlist.count(e):
            return False     
    # It is sublist
    return True

It ensures the sublist never has different elements than list or a greater amount of a common element.

lst=[1,2,2,3,4]
sl1=[2,2,3]
sl2=[2,2,2]
sl3=[2,5]

print(isSubList(sl1,lst)) # True
print(isSubList(sl2,lst)) # False
print(isSubList(sl3,lst)) # False

Would you be satisfied with a Map from Jackson?

ObjectMapper objectMapper = new ObjectMapper();
Map<String, Object> map = objectMapper.readValue(jsonString, new TypeReference<HashMap<String,Object>>(){});

Or maybe a JsonNode?

JsonNode jsonNode = objectMapper.readTree(String jsonString) 

Please note that in upcoming version of C# which is 8, the answers are not true.

All the reference types are non-nullable by default and you can actually do the following:

public string? MyNullableString; 
this.MyNullableString = null; //Valid

However,

public string MyNonNullableString; 
this.MyNonNullableString = null; //Not Valid and you'll receive compiler warning. 

The important thing here is to show the intent of your code. If the "intent" is that the reference type can be null, then mark it so otherwise assigning null value to non-nullable would result in compiler warning.

More info

There also exists a UNIQUE KEY. The main difference between PRIMARY KEY and UNIQUE KEY is that the PRIMARY KEY never takes NULL value while a UNIQUE KEY may take NULL value. Also, there can be only one PRIMARY KEY in a table while UNIQUE KEY may be more than one.

Add more than one class based on the condition:

<div ng-click="AbrirPopUp(s)" 
ng-class="{'class1 class2 class3':!isNew, 
           'class1 class4': isNew}">{{ isNew }}</div>

Apply: class1 + class2 + class3 when isNew=false,

Apply: class1+ class4 when isNew=true

On the side, a trick that can be useful:
If you hold your multiple strings in a TStrings, you just have to use the Text property of the TStrings like in the following example.

Label1.Caption := Memo1.Lines.Text;

And you'll get your multi-line label...

You can also achieve it by using StadiumBorder shape

FlatButton(
  onPressed: () {},
  child: Text('StadiumBorder'),
  shape: StadiumBorder(),
  color: Colors.pink,
  textColor: Colors.white,
),

You can use the following syntax:

#include <map>

std::map<char, char> my_map = {
    { 'A', '1' },
    { 'B', '2' },
    { 'C', '3' }
};

The class which implements KeyListener interface becomes our custom key event listener. This listener can not directly listen the key events. It can only listen the key events through intermediate objects such as JFrame. So

1. Make one Key listener class as

   class MyListener implements KeyListener{
   
      // override all the methods of KeyListener interface.
   }
   

2. Now our class MyKeyListener is ready to listen the key events. But it can not directly do so.

3. Create any object like JFrame object through which MyListener can listen the key events. for that you need to add MyListener object to the JFrame object.

   JFrame f=new JFrame();
   f.addKeyListener(new MyKeyListener);
   

I was also having the same problem. I tried the following and it's working for me now:
Please try the following steps:

Go to..

File > Settings > Appearance & Behavior > System Settings > HTTP Proxy [Under IDE Settings] Enable following option Auto-detect proxy settings

On Mac it's under:

Android Studio > Preferences > Appearance & Behaviour... etc

you can also use the test connection button and check with google.com to see if it works or not.

\ does the job. @Guillaume's answer and @George's comment clearly answer this question. Here I explains why The backslash has to be the very last character before the end of line character. Consider this command:

   mysql -uroot \
   -hlocalhost      

If there is a space after \, the line continuation will not work. The reason is that \ removes the special meaning for the next character which is a space not the invisible line feed character. The line feed character is after the space not \ in this example.

From page 143 of The Swift Programming Language:

You can add a new item to the end of an array by calling the array’s append method

Alternatively, add a new item to the end of an array with the addition assignment operator (+=)

I had this problem on a fresh install on Mac. I installed MariaDB with:

brew install mariadb 

Then started the service:

I was unable to run 'mysql_secure_installation' as it prompted for the root password. Then I noticed in the install output:

So I tried logging in as the username specified in the mysql_install_db output and was successful e.g.

mysql -u jonny

Then at the mysql prompt if you want to set a password for the root user:

SET PASSWORD FOR 'root'@'localhost' = PASSWORD('ToPsEcReT');

I faced this problem when building my project with Jenkins. First, it could not find ant.bat, which was fixed by adding the path to ant.bat to the system environment variable path. Then ant could not find the jdk directory. This was fixed by right-clicking on my computer > properties > advanced > environment variables and creating a new environment variable called JAVA_HOME and assigning it a value of C:\Program Files\Java\jdk1.7.0_21. Don't create this environment variable in User Variables. Create it under System Variables only.
In both cases, I had to restart the system.

As you know JBoss is a purely filesystem based installation. To install you simply unzip a file and thats it. Once you install a certain folder structure is created by default and as you run the JBoss instance for the first time, it creates additional folders for runtime operation. For comparison here is the structure of JBoss AS 7 before and after you start for the first time

Before

jboss-as-7
 |
 |---> standalone
 |      |----> lib
 |      |----> configuration
 |      |----> deployments
 |      
 |---> domain
 |....

After

jboss-as-7
     |
     |---> standalone
     |      |----> lib
     |      |----> configuration
     |      |----> deployments
     |      |----> tmp
     |      |----> data
     |      |----> log
     |      
     |---> domain
     |....

As you can see 3 new folders are created (log, data & tmp). These folders can all be deleted without effecting the application deployed in deployments folder unless your application generated Data that's stored in those folders. In development, its ok to delete all these 3 new folders assuming you don't have any need for the logs and data stored in "data" directory.

For production, ITS NOT RECOMMENDED to delete these folders as there maybe application generated data that stores certain state of the application. For ex, in the data folder, the appserver can save critical Tx rollback logs. So contact your JBoss Administrator if you need to delete those folders for any reason in production.

Good luck!

For a loop where you want to convert an array of strings to an array of bigIntegers do this:

String[] unsorted = new String[n]; //array of Strings
BigInteger[] series = new BigInteger[n]; //array of BigIntegers

for(int i=0; i<n; i++){
    series[i] = new BigInteger(unsorted[i]); //convert String to bigInteger
}

You can also use callto:########### replacing the email code mail with call, at least according to W3Cschool site but I haven't had an opportunity to test it out.

I had to check if Git was installed as part of deploying our CI server. My final Bash script was as follows (Ubuntu server):

if ! builtin type -p git &>/dev/null; then
  sudo apt-get -y install git-core
fi

I know the question was about ASP but maybe somebody will find this answer helpful.

If you have a server behind the IIS 7.5 (e.g. Tomcat). In my case I have a server farm with Tomcat server configured. In such case you can change the timeout using the IIS Manager:

• go to Server Farms -> {Server Name} -> Proxy
• change the value in the Time-out entry box
• click Apply (top-right corner)

or you can change it in the cofig file:

• open %WinDir%\System32\Inetsrv\Config\applicationHost.config
• adjust the server webFarm configuration to be similar to the following

Example:

<webFarm name="${SERVER_NAME}" enabled="true"> 
  <server address="${SERVER_ADDRESS}" enabled="true">
    <applicationRequestRouting httpPort="${SERVER_PORT}" />
  </server>
  <applicationRequestRouting>
    <protocol timeout="${TIME}" />
  </applicationRequestRouting>
</webFarm>

The ${TIME} is in HH:mm:ss format (so if you want to set it to 90 seconds then put there 00:01:30)

In case of Tomcat (and probably other servlet containers) you have to remember to change the timeout in the %TOMCAT_DIR%\conf\server.xml (just search for connectionTimeout attribute in Connector tag, and remember that it is specified in milliseconds)

Take a very common pattern. Class Factory makes Widgets. The Factory class needs to muck about with the internals, because, it is the Factory. Both are implemented in the same file and are, by design and desire and nature, tightly coupled classes -- in fact, Widget is really just an output type from factory.

In C++, make the Factory a friend of Widget class.

In C#, what can we do? The only decent solution that has occurred to me is to invent an interface, IWidget, which only exposes the public methods, and have the Factory return IWidget interfaces.

This involves a fair amount of tedium - exposing all the naturally public properties again in the interface.

Here is some weak adobe documentation on different flash 9 wmode settings.

I've preferred using the params filter for parameter-centric content-type.. I believe that should work in conjunction with the produces attribute.

@GetMapping(value="/person/{id}/", 
            params="format=json",
            produces=MediaType.APPLICATION_JSON_VALUE)
public ResponseEntity<Person> getPerson(@PathVariable Integer id){
    Person person = personMapRepository.findPerson(id);
    return ResponseEntity.ok(person);
} 
@GetMapping(value="/person/{id}/", 
            params="format=xml",
            produces=MediaType.APPLICATION_XML_VALUE)
public ResponseEntity<Person> getPersonXML(@PathVariable Integer id){
    return GetPerson(id); // delegate
}

The issue is with the h1 header margin. You need to try this:

h1 {
 margin-top:0;
}

Another thing you can do is just drag a folder from your computer into the GitHub repository page. This folder does have to have at least 1 item in it, though.

Here's a jquery plugin to do the same: http://s.technabled.com/jquery-foggle

The NoReverseMatch error is saying that Django cannot find a matching url pattern for the url you've provided in any of your installed app's urls.

The NoReverseMatch exception is raised by django.core.urlresolvers when a matching URL in your URLconf cannot be identified based on the parameters supplied.

To start debugging it, you need to start by disecting the error message given to you.

• NoReverseMatch at /my_url/

  This is the url that is currently being rendered, it is this url that your application is currently trying to access but it contains a url that cannot be matched

• Reverse for 'my_url_name'

  This is the name of the url that it cannot find

• with arguments '()' and

  These are the non-keyword arguments its providing to the url

• keyword arguments '{}' not found.

  These are the keyword arguments its providing to the url

• n pattern(s) tried: []

  These are the patterns that it was able to find in your urls.py files that it tried to match against

Start by locating the code in your source relevant to the url that is currently being rendered - the url, the view, and any templates involved. In most cases, this will be the part of the code you're currently developing.

Once you've done this, read through the code in the order that django would be following until you reach the line of code that is trying to construct a url for your my_url_name. Again, this is probably in a place you've recently changed.

Now that you've discovered where the error is occuring, use the other parts of the error message to work out the issue.

The url name

• Are there any typos?
• Have you provided the url you're trying to access the given name?
• If you have set app_name in the app's urls.py (e.g. app_name = 'my_app') or if you included the app with a namespace (e.g. include('myapp.urls', namespace='myapp'), then you need to include the namespace when reversing, e.g. {% url 'myapp:my_url_name' %} or reverse('myapp:my_url_name').

Arguments and Keyword Arguments

The arguments and keyword arguments are used to match against any capture groups that are present within the given url which can be identified by the surrounding () brackets in the url pattern.

Assuming the url you're matching requires additional arguments, take a look in the error message and first take a look if the value for the given arguments look to be correct.

If they aren't correct:

• The value is missing or an empty string

  This generally means that the value you're passing in doesn't contain the value you expect it to be. Take a look where you assign the value for it, set breakpoints, and you'll need to figure out why this value doesn't get passed through correctly.

• The keyword argument has a typo

  Correct this either in the url pattern, or in the url you're constructing.

If they are correct:

• Debug the regex

  You can use a website such as regexr to quickly test whether your pattern matches the url you think you're creating, Copy the url pattern into the regex field at the top, and then use the text area to include any urls that you think it should match against.

  Common Mistakes:

  • Matching against the . wild card character or any other regex characters

    Remember to escape the specific characters with a \ prefix

  • Only matching against lower/upper case characters

    Try using either a-Z or \w instead of a-z or A-Z

• Check that pattern you're matching is included within the patterns tried

  If it isn't here then its possible that you have forgotten to include your app within the INSTALLED_APPS setting (or the ordering of the apps within INSTALLED_APPS may need looking at)

Django Version

In Django 1.10, the ability to reverse a url by its python path was removed. The named path should be used instead.

If you're still unable to track down the problem, then feel free to ask a new question that includes what you've tried, what you've researched (You can link to this question), and then include the relevant code to the issue - the url that you're matching, any relevant url patterns, the part of the error message that shows what django tried to match, and possibly the INSTALLED_APPS setting if applicable.

none of answers helped me, in case when I had several levels of nested arrays. the solution is almost same as @AlienWebguy already did, but with tiny difference.

function nestedToSingle(array $array)
{
    $singleDimArray = [];

    foreach ($array as $item) {

        if (is_array($item)) {
            $singleDimArray = array_merge($singleDimArray, nestedToSingle($item));

        } else {
            $singleDimArray[] = $item;
        }
    }

    return $singleDimArray;
}

test example

$array = [
        'first',
        'second',
        [
            'third',
            'fourth',
        ],
        'fifth',
        [
            'sixth',
            [
                'seventh',
                'eighth',
                [
                    'ninth',
                    [
                        [
                            'tenth'
                        ]
                    ]
                ],
                'eleventh'
            ]
        ],
        'twelfth'
    ];

    $array = nestedToSingle($array);
    print_r($array);

    //output
    array:12 [
        0 => "first"
        1 => "second"
        2 => "third"
        3 => "fourth"
        4 => "fifth"
        5 => "sixth"
        6 => "seventh"
        7 => "eighth"
        8 => "ninth"
        9 => "tenth"
        10 => "eleventh"
        11 => "twelfth"
   ]

I found a pretty simple way to do this. Use a button to open it using an on click listener to start the function openc(), like this:

String fileloc;
private void openc()
{
    Intent takePictureIntent = new Intent(MediaStore.ACTION_IMAGE_CAPTURE);
    File f = null;
    try 
    {
        f = File.createTempFile("temppic",".jpg",getApplicationContext().getCacheDir());
        if (takePictureIntent.resolveActivity(getPackageManager()) != null)
        {               
            takePictureIntent.putExtra(MediaStore.EXTRA_OUTPUT,FileProvider.getUriForFile(profile.this, BuildConfig.APPLICATION_ID+".provider",f));
            fileloc = Uri.fromFile(f)+"";
            Log.d("texts", "openc: "+fileloc);
            startActivityForResult(takePictureIntent, 3);
        }
    } 
    catch (IOException e) 
    {
        e.printStackTrace();
    }
}

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) 
{
    super.onActivityResult(requestCode, resultCode, data);
    if(requestCode == 3 && resultCode == RESULT_OK) {
        Log.d("texts", "onActivityResult: "+fileloc);
        // fileloc is the uri of the file so do whatever with it
    }
}

You can do whatever you want with the uri location string. For instance, I send it to an image cropper to crop the image.

Make sure you have jQuery UI base and the color picker widget included on your page (as well as a copy of jQuery 1.3):

<link rel="stylesheet" href="http://dev.jquery.com/view/tags/ui/latest/themes/flora/flora.all.css" type="text/css" media="screen" title="Flora (Default)">

<script type="text/javascript" src="http://dev.jquery.com/view/tags/ui/latest/ui/ui.core.js"></script>

<script type="text/javascript" src="http://dev.jquery.com/view/tags/ui/latest/ui/ui.colorpicker.js"></script>

If you have those included, try posting your source so we can see what's going on.

You can use PadLeft

var newString = Your_String.PadLeft(4, '0');

For those using jQuery there's a convenient method: http://api.jquery.com/change/

There are various use cases of closures.Here, I am going to explain most important usage of Closure concept.

• Closure can be used to create private methods and variables just like an object-oriented language like java, c++ and so on. Once you implemented private methods and variables, your variables defined inside a function won't be accessible by window object. This helps in data hiding and data security.

const privateClass = () => {
  let name = "sundar";
  function setName(changeName) {
    name = changeName;
  }
  function getName() {
    return name;
  }
  return {
    setName: setName,
    getName: getName,
  };
};

let javaLikeObject = privateClass(); \\ similar to new Class() in OOPS.

console.log(javaLikeObject.getName()); \\this will give sundar
javaLikeObject.setName("suresh");
console.log(javaLikeObject.getName()); \\this will give suresh

• Another real-life example of closure :

Create index.html:

<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Program with Javascript</title>
  </head>
  <body>
    <p id="first"></p>
    <p id="second"></p>
    <button onclick="applyingConcepts()">Click</button>
    <script src="./index.js"></script>
  </body>
</html>

2)In index.js:

  let count = 0;
  return () => {
    document.getElementById("first").innerHTML = count++;
  };
})();

• In this example, when you click a button, then your count will be updated on p#id. Note: You might be wondering what's special in this code. When you inspect, you will notice that you can't change the value of count using the window object. This means you have declared private variable count so this prevents your states from being spoiled by the client.

Add this code

runOnUiThread(new Runnable() { public void run() {
               adapter = new CustomAdapter(anotherdata);
            adapter.notifyDataSetChanged();
            }
        });

1. Create and setup a "tests" folder
   • In the Project sidebar on the left, right-click your project and do New > Directory. Name it "test" or whatever you like.
   • Right-click the folder and choose "Mark Directory As > Test Source Root".
2. Adding JUnit library
   • Right-click your project and choose "Open Module Settings" or hit F4. (Alternatively, File > Project Structure, Ctrl-Alt-Shift-S is probably the "right" way to do this)
   • Go to the "Libraries" group, click the little green plus (look up), and choose "From Maven...".
   • Search for "junit" -- you're looking for something like "junit:junit:4.11".
   • Check whichever boxes you want (Sources, JavaDocs) then hit OK.
   • Keep hitting OK until you're back to the code.

3. Write your first unit test

   • Right-click on your test folder, "New > Java Class", call it whatever, e.g. MyFirstTest.

   • Write a JUnit test -- here's mine:

     import org.junit.Assert;
     import org.junit.Test;
     
     public class MyFirstTest {
         @Test
         public void firstTest() {
             Assert.assertTrue(true);
         }
     }
     

4. Run your tests
   • Right-click on your test folder and choose "Run 'All Tests'". Presto, testo.
   • To run again, you can either hit the green "Play"-style button that appeared in the new section that popped on the bottom of your window, or you can hit the green "Play"-style button in the top bar.

#python3

import datetime
print(
    '1: test-{date:%Y-%m-%d_%H:%M:%S}.txt'.format( date=datetime.datetime.now() )
    )

d = datetime.datetime.now()
print( "2a: {:%B %d, %Y}".format(d))

# see the f" to tell python this is a f string, no .format
print(f"2b: {d:%B %d, %Y}")

print(f"3: Today is {datetime.datetime.now():%Y-%m-%d} yay")

1: test-2018-02-14_16:40:52.txt

2a: March 04, 2018

2b: March 04, 2018

3: Today is 2018-11-11 yay

Description:

Using the new string format to inject value into a string at placeholder {}, value is the current time.

Then rather than just displaying the raw value as {}, use formatting to obtain the correct date format.

It could be done in Bootstrap 4 using the responsive grid columns. One column for the sidebar and one for the main content.

Add this to your module

Public Declare Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As Long)

Or, for 64-bit systems use:

Public Declare PtrSafe Sub Sleep Lib "kernel32" (ByVal dwMilliseconds As LongPtr)

Call it in your macro like so:

Sub Macro1()
'
' Macro1 Macro
'
Do
    Calculate
    Sleep (1000) ' delay 1 second

Loop
End Sub

The correct and working one-line solution for deleting a unique object (named "objectToRemove") from an array of these objects (named "array") in Swift 3 is:

if let index = array.enumerated().filter( { $0.element === objectToRemove }).map({ $0.offset }).first {
   array.remove(at: index)
}

In my case I had to implement MainActivity as Serializable too. Cause I needed to start a service from my MainActivity :

public class MainActivity extends AppCompatActivity implements Serializable {
    ...
    musicCover = new MusicCover(); // A Serializable Object
    ...
    sIntent = new Intent(MainActivity.this, MusicPlayerService.class);
    sIntent.setAction(MusicPlayerService.ACTION_INITIALIZE_COVER);
    sIntent.putExtra(MusicPlayerService.EXTRA_COVER, musicCover);
    startService(sIntent);
}

Example: index = False

import pandas as pd

writer = pd.ExcelWriter("dataframe.xlsx", engine='xlsxwriter')
dataframe.to_excel(writer,sheet_name = dataframe, index=False)
writer.save() 

EditText edit = new EditText(this);

edit.setHorizontallyScrolling(true);
edit.setInputType(EditorInfo.TYPE_NUMBER_FLAG_SIGNED|EditorInfo.TYPE_CLASS_NUMBER);

I have been searching for this same answer all morning and have pretty much found out that it's probably impossible to verify if every email address you ever need to check actually exists at the time you need to verify it. So as a work around, I kind of created a simple PHP script to verify that the email address is formatted correct and it also verifies that the domain name used is correct as well.

If working on EJB client library:

You need to mention the argument for getting the initial context.

InitialContext ctx = new InitialContext();

If you do not, it will look in the project folder for properties file. Also you can include the properties credentials or values in your class file itself as follows:

Properties props = new Properties();
props.put(Context.INITIAL_CONTEXT_FACTORY, "org.jnp.interfaces.NamingContextFactory");
props.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming");
props.put(Context.PROVIDER_URL, "jnp://localhost:1099");

InitialContext ctx = new InitialContext(props);

URL_PKG_PREFIXES: Constant that holds the name of the environment property for specifying the list of package prefixes to use when loading in URL context factories.

The EJB client library is the primary library to invoke remote EJB components.
This library can be used through the InitialContext. To invoke EJB components the library creates an EJB client context via a URL context factory. The only necessary configuration is to parse the value org.jboss.ejb.client.naming for the java.naming.factory.url.pkgs property to instantiate an InitialContext.

If you're looking for a minimalist approach to templates, you can check out JSON Template.

A more full-featured alternative is EJS. It's a bit more similar to something you'd get from Django.

Your mileage may vary for each of these - they're designed for a browser Javascript environment, and not Node.js.

If you actually make use of spring boot run configurations (currently only supported in the Ultimate Edition) it's easy to pre-configure the profiles in "Active Profiles" setting.

parentElement.prepend(newFirstChild);

This is a new addition in (likely) ES7. It is now vanilla JS, probably due to the popularity in jQuery. It is currently available in Chrome, FF, and Opera. Transpilers should be able to handle it until it becomes available everywhere.

P.S. You can directly prepend strings

parentElement.prepend('This text!');

Scanner scan = new Scanner(System.in);
        int i = scan.nextInt();
        Double d = scan.nextDouble();


        String newStr = "";
        Scanner charScanner = new Scanner( System.in ).useDelimiter( "(\\b|\\B)" ) ;
        while( charScanner.hasNext() ) { 
            String  c = charScanner.next();

            if (c.equalsIgnoreCase("\r")) {
                break;
            }
            else {
                newStr += c;    
            }
        }

        System.out.println("String: " + newStr);
        System.out.println("Int: " + i);
        System.out.println("Double: " + d);

This code works fine

I use this code piece while working with indexes for radio group:

radioGroup.check(radioGroup.getChildAt(index).getId());

client.py

import socket

s = socket.socket()
s.connect(('127.0.0.1',12345))
while True:
    str = raw_input("S: ")
    s.send(str.encode());
    if(str == "Bye" or str == "bye"):
        break
    print "N:",s.recv(1024).decode()
s.close()

server.py

import socket

s = socket.socket()
port = 12345
s.bind(('', port))
s.listen(5)
c, addr = s.accept()
print "Socket Up and running with a connection from",addr
while True:
    rcvdData = c.recv(1024).decode()
    print "S:",rcvdData
    sendData = raw_input("N: ")
    c.send(sendData.encode())
    if(sendData == "Bye" or sendData == "bye"):
        break
c.close()

This should be the code for a small prototype for the chatting app you wanted. Run both of them in separate terminals but then just check for the ports.

Just type whoami in command prompt and you'll get the current username.

To fix this, open the SQL Server Management Studio and click New Query. Then type:

USE mydatabase
exec sp_changedbowner 'sa', 'true'

I combined several approaches here. I like the idea of the preprocessor and the indexed list.

There's no extra dynamic allocation, and because of the inlining the compiler might be able to optimize the lookup.

typedef NS_ENUM(NSUInteger, FormatType) { FormatTypeJSON = 0, FormatTypeXML, FormatTypeAtom, FormatTypeRSS, FormatTypeCount };

NS_INLINE NSString *FormatTypeToString(FormatType t) {
  if (t >= FormatTypeCount)
    return nil;

#define FormatTypeMapping(value) [value] = @#value

  NSString *table[FormatTypeCount] = {FormatTypeMapping(FormatTypeJSON),
                                      FormatTypeMapping(FormatTypeXML),
                                      FormatTypeMapping(FormatTypeAtom),
                                      FormatTypeMapping(FormatTypeRSS)};

#undef FormatTypeMapping

  return table[t];
}

I'm not sure how extensively you've searched, but this seems to be similar to what you're searching for:

https://apple.stackexchange.com/questions/83630/create-a-terminal-command-to-open-file-with-chrome

(I just assumed you're using Mac since you used the word "terminal")

Please check: http://man7.org/linux/man-pages/man5/proc.5.html

address           perms offset  dev   inode       pathname
00400000-00452000 r-xp 00000000 08:02 173521      /usr/bin/dbus-daemon

The address field is the address space in the process that the mapping occupies.

The perms field is a set of permissions:

 r = read
 w = write
 x = execute
 s = shared
 p = private (copy on write)

The offset field is the offset into the file/whatever;

dev is the device (major:minor);

inode is the inode on that device.0 indicates that no inode is associated with the memoryregion, as would be the case with BSS (uninitialized data).

The pathname field will usually be the file that is backing the mapping. For ELF files, you can easily coordinate with the offset field by looking at the Offset field in the ELF program headers (readelf -l).

Under Linux 2.0, there is no field giving pathname.

I suppose because you didn't specify plugin version so it triggers the download of associated metadata in order to get the last one.

Otherwise did you try to force local repo usage using -o ?

Try cleaning the project and rebuild, if doesn't work try disabling the Instant Run from Settings>Build>Instant Run in case you are running someone else's code.

can use this to redirect

echo '<meta http-equiv="refresh" content="1; URL=index.php" />';

the content=1 can be change to different value to increase the delay before redirection

I solved the problem by applying box-sizing:border-box; to the table cells themselves, besides doing the same with the input and the wrapper.

If you want to change icons' and texts' colors programmatically:

ColorStateList iconsColorStates = new ColorStateList(
            new int[][]{
                    new int[]{-android.R.attr.state_checked},
                    new int[]{android.R.attr.state_checked}
            },
            new int[]{
                    Color.parseColor("#123456"),
                    Color.parseColor("#654321")
            });

    ColorStateList textColorStates = new ColorStateList(
            new int[][]{
                    new int[]{-android.R.attr.state_checked},
                    new int[]{android.R.attr.state_checked}
            },
            new int[]{
                    Color.parseColor("#123456"),
                    Color.parseColor("#654321")
            });

    navigation.setItemIconTintList(iconsColorStates);
    navigation.setItemTextColor(textColorStates);

You can do it with following code(track by),

<select ng-model="modelName" ng-options="data.name for data in list track by data.id" ></select>

Use std::string and find.

std::string str = "/user/desktop/abc/post/";
bool exists = str.find("/abc/") != std::string::npos;

  SELECT * FROM (SELECT ROW_NUMBER () OVER (ORDER BY sal DESC) row_number, sr,sal FROM empsal) a WHERE (row_number%2) = 1

and

      SELECT * FROM (SELECT ROW_NUMBER () OVER (ORDER BY sal DESC) row_number, sr,sal FROM   empsal) a WHERE (row_number%2) = 0

You can use

$window.scrollTo(x, y);

where x is the pixel along the horizontal axis and y is the pixel along the vertical axis.

1. Scroll to top

   $window.scrollTo(0, 0);
   

2. Focus on element

   $window.scrollTo(0, angular.element('put here your element').offsetTop);   
   

Example

Update:

Also you can use $anchorScroll

Example

I am using CDN for my project and as part of fallback handling, i was using below code,

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <script type="text/javascript">
                if ((typeof jQuery == 'undefined')) {
                    document.write(unescape("%3Cscript src='/Responsive/Scripts/jquery-1.9.1.min.js' type='text/javascript'%3E%3C/script%3E"));   
                }
</script>

Just to verify, i removed CDN reference and execute the code. Its broken and it's never entered into if loop as typeof jQuery is coming as function instead of undefined .

This is because of cached older version of jquery 1.6.1 which return function and break my code because i am using jquery 1.9.1. As i need exact version of jquery, i modified code as below,

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<script type="text/javascript">
            if ((typeof jQuery == 'undefined') || (jQuery.fn.jquery != "1.9.1")) {
                document.write(unescape("%3Cscript src='/Responsive/Scripts/jquery-1.9.1.min.js' type='text/javascript'%3E%3C/script%3E"));   
            }
</script>

Processes are like two people using two different computers, who use the network to share data when necessary. Threads are like two people using the same computer, who don't have to share data explicitly but must carefully take turns.

Conceptually, threads are just multiple worker bees buzzing around in the same address space. Each thread has its own stack, its own program counter, etc., but all threads in a process share the same memory. Imagine two programs running at the same time, but they both can access the same objects.

Contrast this with processes. Processes each have their own address space, meaning a pointer in one process cannot be used to refer to an object in another (unless you use shared memory).

I guess the key things to understand are:

• Both processes and threads can "run at the same time".
• Processes do not share memory (by default), but threads share all of their memory with other threads in the same process.
• Each thread in a process has its own stack and its own instruction pointer.

public static void openWebpage(String urlString) {
    try {
        Desktop.getDesktop().browse(new URL(urlString).toURI());
    } catch (Exception e) {
        e.printStackTrace();
    }
}

You need to define a Remote Java Application in the Eclipse debug configurations:

Open the debug configurations (select project, then open from menu run/debug configurations) Select Remote Java Application in the left tree and press "New" button On the right panel select your web app project and enter 8787 in the port field. Here is a link to a detailed description of this process.

When you start the remote debug configuration Eclipse will attach to the JBoss process. If successful the debug view will show the JBoss threads. There is also a disconnect icon in the toolbar/menu to stop remote debugging.

You'd have to use WebSockets (or some similar protocol module e.g. as supported by the Flash plugin) because a normal browser application simply can't open a pure TCP socket.

The Socket.IO module available for node.js can help a lot, but note that it is not a pure WebSocket module in its own right.

It's actually a more generic communications module that can run on top of various other network protocols, including WebSockets, and Flash sockets.

Hence if you want to use Socket.IO on the server end you must also use their client code and objects. You can't easily make raw WebSocket connections to a socket.io server as you'd have to emulate their message protocol.

I think of it this way, encapsulation is hiding the way something gets done. This can be one or many actions.

Abstraction is related to "why" I am encapsulating it the first place.

I am basically telling the client "You don't need to know much about how I process the payment and calculate shipping, etc. I just want you to tell me you want to 'Checkout' and I will take care of the details for you."

This way I have encapsulated the details by generalizing (abstracting) into the Checkout request.

I really think that abstracting and encapsulation go together.

In Java 8 you can use String.join:

String.join("", Collections.nCopies(n, s));

One possibility might be:

• Create a new div to hold all the extended/arbitrary data
• Do something to ensure that this div is invisible (e.g. CSS plus a class attribute of the div)
• Put the extended/arbitrary data within [X]HTML tags (e.g. as text within cells of a table, or anything else you might like) within this invisible div

$fruits = array (
    "fruits"  => array("a" => "Orange", "b" => "Banana", "c" => "Apple"),
    "numbers" => array(1, 2, 3, 4, 5, 6),
    "holes"   => array("first", 5 => "second", "third")
);

echo $fruits["fruits"]["b"]

outputs 'Banana'

Old question, but alternatively:

virtualenv --python=python3.5 .venv
source .venv/bin/activate

What container are you adding the UserControl to? Generally when you add controls to a Grid, they will stretch to fill the available space (unless their row/column is constrained to a certain width).

for /f "delims=" %%i in (count.txt) do set c=%%i
echo %c%
pause

The provided examples, using csv modules, are great! Besides, you can always simply write to a text file using formatted strings, like the following tentative example:

l = [[1, 2], [2, 3], [4, 5]]

out = open('out.csv', 'w')
for row in l:
    for column in row:
        out.write('%d;' % column)
    out.write('\n')
out.close()

I used ; as separator, because it works best with Excell (one of your requirements).

Hope it helps!

You could simply add this style to the table.

table {
    border-spacing: 15px;
}

setx path "%PATH%; C:\Program Files (x86)\Microsoft Office\root\Office16" /m

This should do the appending to the System Environment Variable Path without any extras added, and keeping the original intact without any loss of data. I have used this command to correct the issue that McAfee's Web Control does to Microsoft's Outlook desktop client.

The quotations are used in the path value because command line sees spaces as a delimiter, and will attempt to execute next value in the command line. The quotations override this behavior and handles everything inside the quotations as a string.

For some reason none of the above answers seemed to be addressing the case of the real first and only first child of the parent.

#element_id > .class_name:first-child

All the above answers will fail if you want to apply the style to only the first class child within this code.

<aside id="element_id">
  Content
  <div class="class_name">First content that need to be styled</div>
  <div class="class_name">
    Second content that don't need to be styled
    <div>
      <div>
        <div class="class_name">deep content - no style</div>
        <div class="class_name">deep content - no style</div>
        <div>
          <div class="class_name">deep content - no style</div>
        </div>
      </div>
    </div>
  </div>
</aside>

The json is kind of odd, it's like the students are properties of the "GetQuestion" object, it should be easy to be a List.....

About the libraries you could use are.

• JavaScriptSerializer
• NewtonSoft.Json
• SimpleJson ...

And there could be many more, but that are what I've used

About the json I don't now maybe something like this

public class GetQuestions
{
    public List<Student> Questions { get; set; }
}

public class Student
{
    public string Code { get; set; }
    public string Questions { get; set; }
}

void Main()
{
    var gq = new GetQuestions
    {
        Questions = new List<Student>
        {
            new Student {Code = "s1", Questions = "Q1,Q2"},
            new Student {Code = "s2", Questions = "Q1,Q2,Q3"},
            new Student {Code = "s3", Questions = "Q1,Q2,Q4"},
            new Student {Code = "s4", Questions = "Q1,Q2,Q5"},
        }
    };

    //Using Newtonsoft.json. Dump is an extension method of [Linqpad][4]
    JsonConvert.SerializeObject(gq).Dump();
}

Linqpad

and the result is this

{
     "Questions":[
        {"Code":"s1","Questions":"Q1,Q2"},
        {"Code":"s2","Questions":"Q1,Q2,Q3"},
        {"Code":"s3","Questions":"Q1,Q2,Q4"},
        {"Code":"s4","Questions":"Q1,Q2,Q5"}
      ]
 }

Yes I know the json is different, but the json that you want with dictionary.

void Main()
{
    var f = new Foo
    {
        GetQuestions = new Dictionary<string, string>
                {
                    {"s1", "Q1,Q2"},
                    {"s2", "Q1,Q2,Q3"},
                    {"s3", "Q1,Q2,Q4"},
                    {"s4", "Q1,Q2,Q4,Q6"},
                }
    };

    JsonConvert.SerializeObject(f).Dump();
}

class Foo
{
    public Dictionary<string, string> GetQuestions { get; set; }
}

And with Dictionary is as you want it.....

{
      "GetQuestions":
       {
              "s1":"Q1,Q2",
              "s2":"Q1,Q2,Q3",
              "s3":"Q1,Q2,Q4",
              "s4":"Q1,Q2,Q4,Q6"
       }
 }

I solved my problem basically with András answer:

1- Log in to MySQL console with root user:

root@9532f0da1a2a:/# mysql -u root -pPASSWORD

And type the root's password to auth.

2- I created a new user:

mysql> CREATE USER 'user'@'hostname' IDENTIFIED BY 'password';

3- Grant all privileges to the new user:

mysql> GRANT ALL PRIVILEGES ON *.* To 'user'@'hostname';

4- Change the Authentication Plugin with the password:

mysql> ALTER USER user IDENTIFIED WITH mysql_native_password BY 'PASSWORD';

Now, phpmyadmin works fine logging the new user.

Properties props = new Properties();
URL resource = getClass().getClassLoader().getResource("data.properties");         
props.load(new InputStreamReader(resource.openStream(), "UTF8"));

Works like a charm

:-)

This is usually caused by truncation (the incoming value is too large to fit in the destination column). Unfortunately SSIS will not tell you the name of the offending column. I use a third-party component to get this information: http://naseermuhammed.wordpress.com/tips-tricks/getting-error-column-name-in-ssis/

$values = get_values();

foreach ((array) $values as $value){
  ...
}

Problem is always null and Casting is in fact the cleaning solution.

I have no idea how it can work automatically, but you can copy "], " together with new line and then use replace function.

Mr Expensive Toys said: Am amazed that this problem is still showing up as it started happening as far back as Honeycomb.

So, the /storage/emulated/0/DCIM/Camera is the same folder as your normal DCIM/Camera folder. Its just a symlink. So the files are actually in the right location you just have an app that put bad data into the MediaStore Database.

When accessing files from your PC your are actually enumerating the MediaStorage database for files. Its not pulling a traditional directory lists. So what you see is based on what is in that database and the path entries in the database. Files in the database pointing to emulated directories aren't shown as they are assumed to be duplicates as its the same physical directory as your normal DCIM/Camera. What is going on is that some poorly written third party apps are inserting entries into the database with the /storage/emulated/0/DCIM/Camera path instead of the proper root path to DCIM/Camera. Which means that the MTP service can't see them when you are hooked up to your PC.

Usually the easiest way to fix the problem is to just clear the MediaStore databases to get the bad entries out of the MediaStore Database and let the system reindex the files and put into the database with the proper paths.

Settings->apps Hit 3 dot menu in top right and select Show System Find Media Storage, Select it, Select Storage, then Clear Data Find External Storage, Select it , Select Storage, then Clear Data Turn phone off, turn phone back on, wait for indexer service to rebuild the data.

When you are done the files should show up with proper directory tree and be visible from the PC. Depending on amount of files on the phone it can take as 10-20 minutes to rebuild the media database as the service walks the phone directories, getting meta data, creating thumbnails, etc.

Basic counting is done as was stated in other answers, and in the pig documentation:

logs = LOAD 'log';
all_logs_in_a_bag = GROUP logs ALL;
log_count = FOREACH all_logs_in_a_bag GENERATE COUNT(logs);
dump log_count

You are right that counting is inefficient, even when using pig's builtin COUNT because this will use one reducer. However, I had a revelation today that one of the ways to speed it up would be to reduce the RAM utilization of the relation we're counting.

In other words, when counting a relation, we don't actually care about the data itself so let's use as little RAM as possible. You were on the right track with your first iteration of the count script.

logs = LOAD 'log'
ones = FOREACH logs GENERATE 1 AS one:int;
counter_group = GROUP ones ALL;
log_count = FOREACH counter_group GENERATE COUNT(ones);
dump log_count

This will work on much larger relations than the previous script and should be much faster. The main difference between this and your original script is that we don't need to sum anything.

This also doesn't have the same problem as other solutions where null values would impact the count. This will count all the rows, regardless of if the first column is null or not.

Yes you can use CASE

UPDATE table 
SET columnB = CASE fieldA 
        WHEN columnA=1 THEN 'x' 
        WHEN columnA=2 THEN 'y' 
        ELSE 'z' 
      END 
WHERE columnC = 1

All the same.

Had a similar problem with a ghost table. Thankfully had an SQL dump from before the failure.

In my case, I had to:

1. Stop mySQL

3. Delete /var/mysql/{dbname}
4. Restart mySQL
5. Recreate empty database
6. Restore dump file

I faced same issue. After downloading everything, still 'punkt' error was there. I searched package on my windows machine at C:\Users\vaibhav\AppData\Roaming\nltk_data\tokenizers and I can see 'punkt.zip' present there. I realized that somehow the zip has not been extracted into C:\Users\vaibhav\AppData\Roaming\nltk_data\tokenizers\punk. Once I extracted the zip, it worked like music.

You might also want to have the client-side function return false.

<asp:LinkButton runat="server" id="button" Text="Click Me" OnClick="myfunction();return false;" AutoPostBack="false" />

You might also consider:

<span runat="server" id="clickableSpan" onclick="myfunction();" class="clickable">Click Me</span>

I use the clickable class to set things like pointer, color, etc. so that its appearance is similar to an anchor tag, but I don't have to worry about it getting posted back or having to do the href="javascript:void(0);" trick.

While I don't think there is a way to fully do this you can take a few measures to stop almost everyone from viewing the HTML.

You can first of all try and stop the inspect menu by doing the following:

I would also suggest using the method that Jonas gave of using his javascript and putting what you don't want people to see in a div with id="element-to-hide" and his given js script to furthermore stop people from inspecting.

I'm pretty sure that it's quite hard to get past that. But then someone can just type view-source

This will basically encrypt your HTML so if you view the source using the method I showed above you will just get encrypted HTML(that is also extremely difficult to unencrypt if you used the extended security option). But you can view the unencrypted HTML through inspecting but we have already blocked that(to a very reasonable extent)

If you are using PHP's password_hash() with the PASSWORD_DEFAULT algorithm to generate the bcrypt hash (which I would assume is a large percentage of people reading this question) be sure to keep in mind that in the future password_hash() might use a different algorithm as the default and this could therefore affect the length of the hash (but it may not necessarily be longer).

From the manual page:

Note that this constant is designed to change over time as new and stronger algorithms are added to PHP. For that reason, the length of the result from using this identifier can change over time. Therefore, it is recommended to store the result in a database column that can expand beyond 60 characters (255 characters would be a good choice).

Using bcrypt, even if you have 1 billion users (i.e. you're currently competing with facebook) to store 255 byte password hashes it would only ~255 GB of data - about the size of a smallish SSD hard drive. It is extremely unlikely that storing the password hash is going to be the bottleneck in your application. However in the off chance that storage space really is an issue for some reason, you can use PASSWORD_BCRYPT to force password_hash() to use bcrypt, even if that's not the default. Just be sure to stay informed about any vulnerabilities found in bcrypt and review the release notes every time a new PHP version is released. If the default algorithm is ever changed it would be good to review why and make an informed decision whether to use the new algorithm or not.

        //Creating the ArrayAdapter instance having the bank name list
        ArrayAdapter aa = new ArrayAdapter(this,android.R.layout.simple_spinner_item,bankNames);
        aa.setDropDownViewResource(android.R.layout.simple_spinner_dropdown_item);
        //Setting the ArrayAdapter data on the Spinner
        spin.setAdapter(aa);
    }


    //Performing action onItemSelected and onNothing selected
    @Override
    public void onItemSelected(AdapterView<?> arg0, View arg1, int position,long id) {
        Toast.makeText(getApplicationContext(), bankNames[position], Toast.LENGTH_LONG).show();
    }

    @Override
    public void onNothingSelected(AdapterView<?> arg0) {
        // TODO Auto-generated method stub

You can try the enable/disable methods instead of using the option method:

$("#txtSearch").datepicker("enable");
$("#txtSearch").datepicker("disable");

This disables the entire textbox. So may be you can use datepicker.destroy() instead:

$(document).ready(function() {
    $("#ddlSearchType").change(function() {
        if ($(this).val() == "Required Date" || $(this).val() == "Submitted Date") {
            $("#txtSearch").datepicker();
        }
        else {
            $("#txtSearch").datepicker("destroy");
        }
    }).change();
});

In my case I was launching a WKWebView and displaying a website. Then (within 25 seconds) I deallocated the WKWebView. But 25-60 seconds after launching the WKWebView I received this "113" error message. I assume the system was trying to signal something to the WKWebView and couldn't find it because it was deallocated.

The fix was simply to leave the WKWebView allocated.

Here's my bash command line to list multiple certificates in order of their expiration, most recently expiring first.

for pem in /etc/ssl/certs/*.pem; do 
   printf '%s: %s\n' \
      "$(date --date="$(openssl x509 -enddate -noout -in "$pem"|cut -d= -f 2)" --iso-8601)" \
      "$pem"
done | sort

Sample output:

2015-12-16: /etc/ssl/certs/Staat_der_Nederlanden_Root_CA.pem
2016-03-22: /etc/ssl/certs/CA_Disig.pem
2016-08-14: /etc/ssl/certs/EBG_Elektronik_Sertifika_Hizmet_S.pem

If this is for some configuration file processing, consider using Apache configuration. https://commons.apache.org/proper/commons-configuration/javadocs/v1.10/apidocs/index.html?org/apache/commons/configuration/PropertiesConfiguration.html It has way to multiple values to single key- The format is bit different though

key=value1,value2,valu3 gives three values against same key.

Another alternate approach to Diego's is to use a library:

https://github.com/airbnb/DeepLinkDispatch

You can easily declare the URIs you'd like to handle and the parameters you'd like to extract through annotations on the Activity, like:

@DeepLink("path/to/what/i/want")
public class SomeActivity extends Activity {
  ...
}

As a plus, the query parameters will also be passed along to the Activity as well.

The big downside of your current approach is its inefficiency with large search result sets, as you have to pull down the entire result set from the database each time, even though you only intend to display one page of results.

In order to only pull down the objects you actually need from the database, you have to use pagination on a QuerySet, not a list. If you do this, Django actually slices the QuerySet before the query is executed, so the SQL query will use OFFSET and LIMIT to only get the records you will actually display. But you can't do this unless you can cram your search into a single query somehow.

Given that all three of your models have title and body fields, why not use model inheritance? Just have all three models inherit from a common ancestor that has title and body, and perform the search as a single query on the ancestor model.

You can match those three groups separately, and make sure that they all present. Also, [^\w] seems a bit too broad, but if that's what you want you might want to replace it with \W.

Here's what I put together. It works on the select mobile device I needed it for, but I'm not sure how universal the solution is

It's easy to create a custom lookup, there's an __ne lookup example in Django's official documentation.

You need to create the lookup itself first:

from django.db.models import Lookup

class NotEqual(Lookup):
    lookup_name = 'ne'

    def as_sql(self, compiler, connection):
        lhs, lhs_params = self.process_lhs(compiler, connection)
        rhs, rhs_params = self.process_rhs(compiler, connection)
        params = lhs_params + rhs_params
        return '%s <> %s' % (lhs, rhs), params

Then you need to register it:

from django.db.models import Field
Field.register_lookup(NotEqual)

And now you can use the __ne lookup in your queries like this:

results = Model.objects.exclude(a=True, x__ne=5)

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

void repeat_char(unsigned int cnt, char ch) {
    char buffer[cnt + 1];
    /*assuming you want to repeat the c character 30 times*/
    memset(buffer,ch,cnd); buffer[cnt]='\0';
    printf("%s",buffer)
}

If 'localhost' doesn't work but 127.0.0.1 does. Make sure your local hosts file points to the correct location. (/etc/hosts for linux/mac, C:\Windows\System32\drivers\etc\hosts for windows).

Also, make sure your user is allowed to connect to whatever database you're trying to select.

Update: Consider using git update-index --skip-worktree [<file>...] instead, thanks @danShumway! See Borealid's explanation on the difference of the two options.

Old answer:

If you need to ignore local changes to tracked files (we have that with local modifications to config files), use git update-index --assume-unchanged [<file>...].

for the sake of completeness, you could use:

(DT_STR,8, 1252) (YEAR(GetDate()) * 10000 + MONTH(GetDate()) * 100 + DAY(GetDate()))

for YYYYMMDD or

RIGHT("000000" + (DT_STR,8, 1252) (DAY(GetDate()) * 1000000 + MONTH(GetDate()) * 10000 + YEAR(GetDate())), 8)

for DDMMYYYY (without hyphens). If you want / need the date as integer (e.g. for _key-columns in DWHs), just remove the DT_STR / RIGTH function and do just the math.

It sounds like you are on the right track with your directory structure. When you compile the dependent code, specify the -classpath argument of javac. Use the parent directory of the com directory, where com, in turn, contains company/thing/YourClass.class

So, when you do this:

javac -classpath <parent> client.java

The <parent> should be referring to the parent of com. If you are in com, it would be ../.

Try this solution for keep selected value in dropdown:

<form action="<?php echo get_page_link(); ?>" method="post">
    <select name="<?php echo $field_key['key']; ?>" onchange="javascript: 
       submit()">
    <option value="">All Category</option>
    <?php 
    foreach( $field['choices'] as $key => $value ){ 
       if($post_key==$key){ ?>
          <option value="<?php echo $key; ?>" selected><?php echo $value; ?></option>
<?php
   }else{?>
  <option value="<?php echo $key; ?>"><?php echo $value; ?></option>
 <?php }
  }?>
 </select>
</form>

You can use clientWidth or offsetWidth Mozilla developer network reference

It would be like:

document.getElementById("yourDiv").clientWidth; // returns number, like 728

or with borders width :

document.getElementById("yourDiv").offsetWidth; // 728 + borders width

More precisely, add the code below to the private void InitializeComponent() method of the Form class:

this.FormBorderStyle = System.Windows.Forms.FormBorderStyle.FixedSingle;

Just a note for people who may have found this later (and want java way of achieving this); FirefoxOptions is also capable of enabling the headless mode:

FirefoxOptions firefoxOptions = new FirefoxOptions();
firefoxOptions.setHeadless(true);

For those of you who require to redirect before fully initalizing a router using React Router or React Router Dom You can provide a redirect by simply accesing the history object and pushing a new state onto it within your constructur of app.js. Consider the following:

function getSubdomain(hostname) {
    let regexParse = new RegExp('[a-z\-0-9]{2,63}\.[a-z\.]{2,5}$');
    let urlParts = regexParse.exec(hostname);
    return hostname.replace(urlParts[0], '').slice(0, -1);
}

class App extends Component {

    constructor(props) {
        super(props);


        this.state = {
            hostState: true
        };

        if (getSubdomain(window.location.hostname).length > 0) {
            this.state.hostState = false;
            window.history.pushState('', '', './login');
        } else {
            console.log(getSubdomain(window.location.hostname));
        }

    }


    render() {
        return (

            <BrowserRouter>
                {this.state.hostState ? (
                    <div>
                        <Route path="/login" component={LoginContainer}/>
                        <Route path="/" component={PublicContainer}/>
                    </div>
                ) : (
                    <div>
                        <Route path="/login" component={LoginContainer}/>
                    </div>
                )

                }
            </BrowserRouter>)
    }


}

Here we want to change the output Routes dependant on a subdomain, by interacting with the history object before the component renders we can effectively redirect while still leaving our routes in tact.

window.history.pushState('', '', './login');

I got the same problem when accessing mysql with root. The problem I found is that some database files does not have permission by the mysql user, which is the user that started the mysql server daemon.

We can check this with ls -l /var/lib/mysql command, if the mysql user does not have permission of reading or writing on some files or directories, that might cause problem. We can change the owner or mode of those files or directories with chown/chmod commands.

After these changes, restart the mysqld daemon and login with root with command:

mysql -u root

Then change passwords or create other users for logging into mysql.

Subplot Colorbar

For subplots with scatter, you can trick a colorbar onto your axes by building the "mappable" with the help of a secondary figure and then adding it to your original plot.

As a continuation of the above example:

import numpy as np
import matplotlib.pyplot as plt

x = np.arange(10)
y = x
t = x
fig, (ax1, ax2) = plt.subplots(1, 2)
ax1.scatter(x, y, c=t, cmap='viridis')
ax2.scatter(x, y, c=t, cmap='viridis_r')


# Build your secondary mirror axes:
fig2, (ax3, ax4) = plt.subplots(1, 2)

# Build maps that parallel the color-coded data
# NOTE 1: imshow requires a 2-D array as input
# NOTE 2: You must use the same cmap tag as above for it match
map1 = ax3.imshow(np.stack([t, t]),cmap='viridis')
map2 = ax4.imshow(np.stack([t, t]),cmap='viridis_r')

# Add your maps onto your original figure/axes
fig.colorbar(map1, ax=ax1)
fig.colorbar(map2, ax=ax2)
plt.show()

Note that you will also output a secondary figure that you can ignore.

Run:

And make sure that Android Studio and Android Studio environment variable refrence to same location.

I fix this by copying Android Studio from:

D:\Program Files\Android

to

C:\Program Files\Android

Set is used for setting object references, as opposed to assigning a value.

If your need to redirect to an action outside the controller this will work.

return RedirectToAction("ACTION", "CONTROLLER", new { id = 99 });

I had the same problem in Sublime..

1. Right click on my computer
2. Advanced system settings
3. Environment variables
4. in system variables, change path to location of '...\MinGW\bin'

Example: D:\work\sublime\MinGW\bin

threading.get_ident() works, or threading.current_thread().ident (or threading.currentThread().ident for Python < 2.6).

Here is Neal Gafter's blog one of the pioneers introducing closures in Java. His post on closures from January 28, 2007 is named A Definition of Closures On his blog there is lots of information to get you started as well as videos. An here is an excellent Google talk - Advanced Topics In Programming Languages - Closures For Java with Neal Gafter, as well.

UPDATE: In iPhone OS 3.0 and later UITableViewCell now has a backgroundColor property that makes this really easy (especially in combination with the [UIColor colorWithPatternImage:] initializer). But I'll leave the 2.0 version of the answer here for anyone that needs it…

It's harder than it really should be. Here's how I did this when I had to do it:

You need to set the UITableViewCell's backgroundView property to a custom UIView that draws the border and background itself in the appropriate colors. This view needs to be able to draw the borders in 4 different modes, rounded on the top for the first cell in a section, rounded on the bottom for the last cell in a section, no rounded corners for cells in the middle of a section, and rounded on all 4 corners for sections that contain one cell.

Unfortunately I couldn't figure out how to have this mode set automatically, so I had to set it in the UITableViewDataSource's -cellForRowAtIndexPath method.

It's a real PITA but I've confirmed with Apple engineers that this is currently the only way.

Update Here's the code for that custom bg view. There's a drawing bug that makes the rounded corners look a little funny, but we moved to a different design and scrapped the custom backgrounds before I had a chance to fix it. Still this will probably be very helpful for you:

        replaceChar("abcdefaa","a");
    }

}

You could use relative imports (python >= 2.5):

EDIT: added another dot '.' to go up two packages

The document says that you can use values to group the queryset .

class Travel(models.Model):
    interest = models.ForeignKey(Interest)
    user = models.ForeignKey(User)
    time = models.DateTimeField(auto_now_add=True)

# Find the travel and group by the interest:

>>> Travel.objects.values('interest').annotate(Count('user'))
<QuerySet [{'interest': 5, 'user__count': 2}, {'interest': 6, 'user__count': 1}]>
# the interest(id=5) had been visited for 2 times, 
# and the interest(id=6) had only been visited for 1 time.

>>> Travel.objects.values('interest').annotate(Count('user', distinct=True)) 
<QuerySet [{'interest': 5, 'user__count': 1}, {'interest': 6, 'user__count': 1}]>
# the interest(id=5) had been visited by only one person (but this person had 
#  visited the interest for 2 times

You can find all the books and group them by name using this code:

Book.objects.values('name').annotate(Count('id')).order_by() # ensure you add the order_by()

You can watch some cheet sheet here.

ps -o uid,pid,cmd|awk '{if($1=="username" && $3=="your command") print $2}'|xargs kill -15

I ended up here and my issue was that I was querying for

{$not: {email: /@domain.com/}}

instead of

{email: {$not: /@domain.com/}}

ListView uses clear().

But, if you're just doing it for RecyclerView. First you have to clear your RecyclerView.Adapter with notifyItemRangeRemoved(0,size)

Then, only you recyclerView.removeAllViewsInLayout().

Use

window.location.hash

Consider that all the above methods fail when your standard deviation gets very large due to huge outliers.

(Simalar as the average caluclation fails and should rather caluclate the median. Though, the average is "more prone to such an error as the stdDv".)

You could try to iteratively apply your algorithm or you filter using the interquartile range: (here "factor" relates to a n*sigma range, yet only when your data follows a Gaussian distribution)

import numpy as np

def sortoutOutliers(dataIn,factor):
    quant3, quant1 = np.percentile(dataIn, [75 ,25])
    iqr = quant3 - quant1
    iqrSigma = iqr/1.34896
    medData = np.median(dataIn)
    dataOut = [ x for x in dataIn if ( (x > medData - factor* iqrSigma) and (x < medData + factor* iqrSigma) ) ] 
    return(dataOut)

For creating a variable which is read-only in all modules except the one it's declared in:

// Header1.h:

#ifndef SOURCE1_C
   extern const int MyVar;
#endif

// Source1.c:

#define SOURCE1_C
#include Header1.h // MyVar isn't seen in the header

int MyVar; // Declared in this file, and is writeable

// Source2.c

#include Header1.h // MyVar is seen as a constant, declared elsewhere

Try this:

INSERT INTO MyTable1 (Col1, Col2, Col4)
   SELECT Col1, Col2, Col3 FROM MyTable2

<input type="text" autocomplete="off"/>

Should work. Alternatively, use:

<form autocomplete="off" … >

for the entire form (see this related question).

You can use "translateX(-100%)" and "text-align: right" if your absolute element is "display: inline-block"

<div class="box">
<div class="absolute-right"></div>
</div>

<style type="text/css">
.box{
    text-align: right;
}
.absolute-right{
    display: inline-block;
    position: absolute;
}

/*The magic:*/
.absolute-right{
-moz-transform: translateX(-100%);
-ms-transform: translateX(-100%);
-webkit-transform: translateX(-100%);
-o-transform: translateX(-100%);
transform: translateX(-100%);
}
</style>

You will get absolute-element aligned to the right relative its parent

Step 1: Get HttpURLConnection object

URL url = new URL(urlToConnect);
HttpURLConnection httpUrlConnection = (HttpURLConnection) url.openConnection();

Step 2: Add headers to the HttpURLConnection using setRequestProperty method.

Map<String, String> headers = new HashMap<>();

headers.put("X-CSRF-Token", "fetch");
headers.put("content-type", "application/json");

for (String headerKey : headers.keySet()) {
    httpUrlConnection.setRequestProperty(headerKey, headers.get(headerKey));
}

Reference link

A much simpler solution is to create a soft link point to whatever you want, such as

link -s /var/lib/docker /mnt/whatever

It works for me on my CentOS 6.5 server.

.so files are dynamic libraries. The suffix stands for "shared object", because all the applications that are linked with the library use the same file, rather than making a copy in the resulting executable.

.a files are static libraries. The suffix stands for "archive", because they're actually just an archive (made with the ar command -- a predecessor of tar that's now just used for making libraries) of the original .o object files.

.la files are text files used by the GNU "libtools" package to describe the files that make up the corresponding library. You can find more information about them in this question: What are libtool's .la file for?

Static and dynamic libraries each have pros and cons.

Static pro: The user always uses the version of the library that you've tested with your application, so there shouldn't be any surprising compatibility problems.

Static con: If a problem is fixed in a library, you need to redistribute your application to take advantage of it. However, unless it's a library that users are likely to update on their own, you'd might need to do this anyway.

Dynamic pro: Your process's memory footprint is smaller, because the memory used for the library is amortized among all the processes using the library.

Dynamic pro: Libraries can be loaded on demand at run time; this is good for plugins, so you don't have to choose the plugins to be used when compiling and installing the software. New plugins can be added on the fly.

Dynamic con: The library might not exist on the system where someone is trying to install the application, or they might have a version that's not compatible with the application. To mitigate this, the application package might need to include a copy of the library, so it can install it if necessary. This is also often mitigated by package managers, which can download and install any necessary dependencies.

Dynamic con: Link-Time Optimization is generally not possible, so there could possibly be efficiency implications in high-performance applications. See the Wikipedia discussion of WPO and LTO.

Dynamic libraries are especially useful for system libraries, like libc. These libraries often need to include code that's dependent on the specific OS and version, because kernel interfaces have changed. If you link a program with a static system library, it will only run on the version of the OS that this library version was written for. But if you use a dynamic library, it will automatically pick up the library that's installed on the system you run on.

I think you should use "textAlign" instead of "text-align".

Building on the brilliant logic / code from mathematix and scottyc, I submit:

DECLARE @a INT, @b INT, @c INT = 0

WHILE @c < 100
    BEGIN
        SET @c += 1
        SET @a = ROUND(RAND()*100,0)-50
        SET @b = ROUND(RAND()*100,0)-50
        SELECT @a AS a, @b AS b,
            @a - ( ABS(@a-@b) + (@a-@b) ) / 2 AS MINab,
            @a + ( ABS(@b-@a) + (@b-@a) ) / 2 AS MAXab,
            CASE WHEN (@a <= @b AND @a = @a - ( ABS(@a-@b) + (@a-@b) ) / 2)
            OR (@a >= @b AND @a = @a + ( ABS(@b-@a) + (@b-@a) ) / 2)
            THEN 'Success' ELSE 'Failure' END AS Status
    END

Although the jump from scottyc's MIN function to the MAX function should have been obvious to me, it wasn't, so I've solved for it and included it here: SELECT @a + ( ABS(@b-@a) + (@b-@a) ) / 2. The randomly generated numbers, while not proof, should at least convince skeptics that both formulae are correct.

Personally I like this.

convert -density 300 -trim test.pdf -quality 100 test.jpg

It's a little over twice the file size, but it looks better to me.

-density 300 sets the dpi that the PDF is rendered at.

-trim removes any edge pixels that are the same color as the corner pixels.

-quality 100 sets the JPEG compression quality to the highest quality.

Things like -sharpen don't work well with text because they undo things your font rendering system did to make it more legible.

If you actually want it blown up use resize here and possibly a larger dpi value of something like targetDPI * scalingFactor That will render the PDF at the resolution/size you intend.

The STAThreadAttribute marks a thread to use the Single-Threaded COM Apartment if COM is needed. By default, .NET won't initialize COM at all. It's only when COM is needed, like when a COM object or COM Control is created or when drag 'n' drop is needed, that COM is initialized. When that happens, .NET calls the underlying CoInitializeEx function, which takes a flag indicating whether to join the thread to a multi-threaded or single-threaded apartment.

Why is STAThread required?

In your case, the user root won't have any issues. But in certain cases where you're required to login under SSH as a different user, make sure the directory you're scp-ing has adequate permissions for the user you're SSH-ing.

Any Java collection can be made to be Thread-safe like so:

List newList = Collections.synchronizedList(oldList);

Or to create a brand new thread-safe list:

List newList = Collections.synchronizedList(new ArrayList());

http://download.oracle.com/javase/6/docs/api/java/util/Collections.html#synchronizedList(java.util.List)

You can use the built-in map along with a lambda expression:

my_list = [0.2111111111, 0.5, 0.3777777777]
my_list_rounded = list(map(lambda x: round(x, ndigits=2), my_list))
my_list_rounded                                                                                                                                                                                                                 
Out[3]: [0.21, 0.5, 0.38]

Alternatively you could also create a named function for the rounding up to a specific digit using partial from the functools module for working with higher order functions:

from functools import partial

my_list = [0.2111111111, 0.5, 0.3777777777]
round_2digits = partial(round, ndigits=2)
my_list_rounded = list(map(round_2digits, my_list))
my_list_rounded                                                                                                                                                                                                                 
Out[6]: [0.21, 0.5, 0.38]

JavaScript has a RegExp object which does what you want. The String object has a match() function that will help you out.

var matches = text.match(/price\[(\d+)\]\[(\d+)\]/);
var productId = matches[1];
var shopId    = matches[2];

For others come to here:
If you happen to put your docker command in a file, say run.sh, check your line separator. In Linux, it should be LR, otherwise you would get the same error.

To answer the other half of the question, you can call:

return PartialView("viewname");

when you want to return partial HTML. You'll just have to find some way to decide whether the request wants JSON or HTML, perhaps based on a URL part/parameter.

It seems that using mongoose there is a limit of more than 1000 documents, when using

Potato.collection.insert(potatoBag, onInsert);

You can use:

var bulk = Model.collection.initializeOrderedBulkOp();

async.each(users, function (user, callback) {
    bulk.insert(hash);
}, function (err) {
    var bulkStart = Date.now();
    bulk.execute(function(err, res){
        if (err) console.log (" gameResult.js > err " , err);
        console.log (" gameResult.js > BULK TIME  " , Date.now() - bulkStart );
        console.log (" gameResult.js > BULK INSERT " , res.nInserted)
      });
});

But this is almost twice as fast when testing with 10000 documents:

function fastInsert(arrOfResults) {
var startTime = Date.now();
    var count = 0;
    var c = Math.round( arrOfResults.length / 990);

    var fakeArr = [];
    fakeArr.length = c;
    var docsSaved = 0

    async.each(fakeArr, function (item, callback) {

            var sliced = arrOfResults.slice(count, count+999);
            sliced.length)
            count = count +999;
            if(sliced.length != 0 ){
                    GameResultModel.collection.insert(sliced, function (err, docs) {
                            docsSaved += docs.ops.length
                            callback();
                    });
            }else {
                    callback()
            }
    }, function (err) {
            console.log (" gameResult.js > BULK INSERT AMOUNT: ", arrOfResults.length, "docsSaved  " , docsSaved, " DIFF TIME:",Date.now() - startTime);
    });
}

What "exactly" an API key is used for depends very much on who issues it, and what services it's being used for. By and large, however, an API key is the name given to some form of secret token which is submitted alongside web service (or similar) requests in order to identify the origin of the request. The key may be included in some digest of the request content to further verify the origin and to prevent tampering with the values.

Typically, if you can identify the source of a request positively, it acts as a form of authentication, which can lead to access control. For example, you can restrict access to certain API actions based on who's performing the request. For companies which make money from selling such services, it's also a way of tracking who's using the thing for billing purposes. Further still, by blocking a key, you can partially prevent abuse in the case of too-high request volumes.

In general, if you have both a public and a private API key, then it suggests that the keys are themselves a traditional public/private key pair used in some form of asymmetric cryptography, or related, digital signing. These are more secure techniques for positively identifying the source of a request, and additionally, for protecting the request's content from snooping (in addition to tampering).

For me, you can't. But if that suits your needs, you could have speed and formatting by copying the whole range at once, instead of looping:

range("B2:B5002").Copy Destination:=Sheets("Output").Cells(startrow, 2)

And, by the way, you can build a custom range string, like Range("B2:B4, B6, B11:B18")

edit: if your source is "sparse", can't you just format the destination at once when the copy is finished ?

Go into your css and add that to it then will automatically block the submission of your formular as long as you have submit input if you no longer want it you can delete it or type activate and deactivate instead

 input:disabled {
        background: gainsboro;
      }
      input[value]:disabled {
        color: whitesmoke;
      }

Define a callback interface to receive whatever parameters you want to pass along in the completion notification. Then invoke it at the end of the task.

You could even write a general wrapper for Runnable tasks, and submit these to ExecutorService. Or, see below for a mechanism built into Java 8.

class CallbackTask implements Runnable {

  private final Runnable task;

  private final Callback callback;

  CallbackTask(Runnable task, Callback callback) {
    this.task = task;
    this.callback = callback;
  }

  public void run() {
    task.run();
    callback.complete();
  }

}

With CompletableFuture, Java 8 included a more elaborate means to compose pipelines where processes can be completed asynchronously and conditionally. Here's a contrived but complete example of notification.

import java.util.concurrent.CompletableFuture;
import java.util.concurrent.ThreadLocalRandom;
import java.util.concurrent.TimeUnit;

public class GetTaskNotificationWithoutBlocking {

  public static void main(String... argv) throws Exception {
    ExampleService svc = new ExampleService();
    GetTaskNotificationWithoutBlocking listener = new GetTaskNotificationWithoutBlocking();
    CompletableFuture<String> f = CompletableFuture.supplyAsync(svc::work);
    f.thenAccept(listener::notify);
    System.out.println("Exiting main()");
  }

  void notify(String msg) {
    System.out.println("Received message: " + msg);
  }

}

class ExampleService {

  String work() {
    sleep(7000, TimeUnit.MILLISECONDS); /* Pretend to be busy... */
    char[] str = new char[5];
    ThreadLocalRandom current = ThreadLocalRandom.current();
    for (int idx = 0; idx < str.length; ++idx)
      str[idx] = (char) ('A' + current.nextInt(26));
    String msg = new String(str);
    System.out.println("Generated message: " + msg);
    return msg;
  }

  public static void sleep(long average, TimeUnit unit) {
    String name = Thread.currentThread().getName();
    long timeout = Math.min(exponential(average), Math.multiplyExact(10, average));
    System.out.printf("%s sleeping %d %s...%n", name, timeout, unit);
    try {
      unit.sleep(timeout);
      System.out.println(name + " awoke.");
    } catch (InterruptedException abort) {
      Thread.currentThread().interrupt();
      System.out.println(name + " interrupted.");
    }
  }

  public static long exponential(long avg) {
    return (long) (avg * -Math.log(1 - ThreadLocalRandom.current().nextDouble()));
  }

}

Relying on the raised exception is not the fastest, readable nor reliable solution.
I'd do the following :

my_string.should =~ /^[0-9]+$/
