Attaching / Detaching

Eloquent also provides a few additional helper methods to make working with related models more convenient. For example, let's imagine a user can have many roles and a role can have many users. To attach a role to a user by inserting a record in the intermediate table that joins the models, use the attach method:

$user = App\User::find(1);

$user->roles()->attach($roleId);

When attaching a relationship to a model, you may also pass an array of additional data to be inserted into the intermediate table:

$user->roles()->attach($roleId, ['expires' => $expires]);

You can also use Sync if you want to remove old roles and only keep the new ones you are attaching now

$user->roles()->sync([1 => ['expires' => $expires], 2 => ['expires' => $expires]);

The default behaviour can be changed by passing a 'false' as a second argument. This will attach the roles with ids 1,2,3 without affecting the existing roles.

In this mode sync behaves similar to the attach method.

$user->roles()->sync([1 => ['expires' => $expires], 2 => ['expires' => $expires], false);

I'm now using SparkleShare https://www.sparkleshare.org/

works on mac, linux and windows.

Use ShellJS module.

exec function without providing callback.

Example:

var version = exec('node -v').output;

This is an error that you see when your emulator has the "Use host GPU" setting checked. If you uncheck it then the error goes away. Of course, then your emulator is not as responsive anymore.

Sometimes it would be nice to have operator overloading, friend classes and multiple inheritance.

However I still think it was a good decision. If Java would have had operator overloading then we could never be sure of operator meanings without looking through source code. At present that's not necessary. And I think your example of using methods instead of operator overloading is also quite readable. If you want to make things more clear you could always add a comment above hairy statements.

// a = b + c
Complex a, b, c; a = b.add(c);

var x = from t in types
        group t by t.Type into grouped
        select new { type = grouped.Key,
                     count = grouped.Count() };

The standard Python libraries don't include any tzinfo classes (but see pep 431). I can only guess at the reasons. Personally I think it was a mistake not to include a tzinfo class for UTC, because that one is uncontroversial enough to have a standard implementation.

Edit: Although there's no implementation in the library, there is one given as an example in the tzinfo documentation.

from datetime import timedelta, tzinfo

ZERO = timedelta(0)

# A UTC class.

class UTC(tzinfo):
    """UTC"""

    def utcoffset(self, dt):
        return ZERO

    def tzname(self, dt):
        return "UTC"

    def dst(self, dt):
        return ZERO

utc = UTC()

To use it, to get the current time as an aware datetime object:

from datetime import datetime 

now = datetime.now(utc)

There is datetime.timezone.utc in Python 3.2+:

from datetime import datetime, timezone 

now = datetime.now(timezone.utc)

In order to create the drawable directory structure for different image densities, You need to:

1. Right-click on the \res folder
2. Select new > android resource directory

3. In the New Resource Directory window, under Available qualifiers resource type section, select drawable.

4. Add density and choose the appropriate size.

For those interested, these are the only alternatives so far:

1) Using these Functions:

http://wi-fizzle.com/downloads/base64.sql

2) If you already have the sys_eval UDF, (Linux) you can do this:

sys_eval(CONCAT("echo '",myField,"' | base64"));

The first method is known to be slow. The problem with the second one, is that the encoding is actually happening "outside" MySQL, which can have encoding problems (besides the security risks that you are adding with sys_* functions).

Unfortunately there is no UDF compiled version (which should be faster) nor a native support in MySQL (Posgresql supports it!).

It seems that the MySQL development team are not interested in implement it as this function already exists in other languages, which seems pretty silly to me.

Related to the question in your answer:

You have multiple options to achieve this that are way better:

Let's assume you have a model which you pass to the view:

$model = Model::find(1);
View::make('view')->withModel($model);

Now in your Model you could have a function:

public function someFunction() {
    // do something
}

In your view you could call that function directly:

{{$model->someFunction()}}

This is nice if you want to do something with the model (the dataset).

If not you can still make a static function in the model:

public static function someStaticFunction($var1, $var2) {
    // do something
}

And then:

{{App\Model::someStaticFunction($yourVar1,$yourVar2)}}

Hope it helps.

Simple Example:

print("foo %d, bar %d" % (1,2))

I had serious issues with Timezones and such. The way Python handles all that happen to be pretty confusing (to me). Things seem to be working fine using the calendar module (see links 1, 2, 3 and 4).

>>> import datetime
>>> import calendar
>>> aprilFirst=datetime.datetime(2012, 04, 01, 0, 0)
>>> calendar.timegm(aprilFirst.timetuple())
1333238400

this is for swift 4.2, 5 and 5+

let alert = UIAlertController(title: "ooops!", message: "Unable to login", preferredStyle: .alert)

alert.addAction(UIAlertAction(title: "Ok", style: .default, handler: nil))

self.present(alert, animated: true)

Yep:

WITH tab (
  bla bla
)

INSERT INTO dbo.prf_BatchItemAdditionalAPartyNos (  BatchID,                                                        AccountNo,
APartyNo,
SourceRowID)    

SELECT * FROM tab

Note that this is for SQL Server, which supports multiple CTEs:

WITH x AS (), y AS () INSERT INTO z (a, b, c) SELECT a, b, c FROM y

Teradata allows only one CTE and the syntax is as your example.

Reflection and dynamic value access are correct solutions to this question but are quite slow. If your want something faster then you can create dynamic method using expressions:

  object value = GetValue();
  string propertyName = "MyProperty";

  var parameter = Expression.Parameter(typeof(object));
  var cast = Expression.Convert(parameter, value.GetType());
  var propertyGetter = Expression.Property(cast, propertyName);
  var castResult = Expression.Convert(propertyGetter, typeof(object));//for boxing

  var propertyRetriver = Expression.Lambda<Func<object, object>>(castResult, parameter).Compile();

 var retrivedPropertyValue = propertyRetriver(value);

This way is faster if you cache created functions. For instance in dictionary where key would be the actual type of object assuming that property name is not changing or some combination of type and property name.

In case you don't have access to functools.partial, you could use a wrapper function for this, as well.

def target(lock):
    def wrapped_func(items):
        for item in items:
            # Do cool stuff
            if (... some condition here ...):
                lock.acquire()
                # Write to stdout or logfile, etc.
                lock.release()
    return wrapped_func

def main():
    iterable = [1, 2, 3, 4, 5]
    pool = multiprocessing.Pool()
    lck = multiprocessing.Lock()
    pool.map(target(lck), iterable)
    pool.close()
    pool.join()

This makes target() into a function that accepts a lock (or whatever parameters you want to give), and it will return a function that only takes in an iterable as input, but can still use all your other parameters. That's what is ultimately passed in to pool.map(), which then should execute with no problems.

Yes with Virtual Host you can have as many parallel programs as you want:

If path is not hardcoded in any script then your websites should work seamlessly.

You could run: mvn exec:exec -Dexec.args="arg1".

This will pass the argument arg1 to your program.

You should specify the main class fully qualified, for example, a Main.java that is in a package test would need

mvn exec:java  -Dexec.mainClass=test.Main

By using the -f parameter, as decribed here, you can also run it from other directories.

mvn exec:java -Dexec.mainClass=test.Main -f folder/pom.xm

For multiple arguments, simply separate them with a space as you would at the command line.

mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="arg1 arg2 arg3"

For arguments separated with a space, you can group using 'argument separated with space' inside the quotation marks.

mvn exec:java -Dexec.mainClass=test.Main -Dexec.args="'argument separated with space' 'another one'"

When I used policy before I set the default authentication scheme into it as well. I had modified the DefaultPolicy so it was slightly different. However the same should work for add policy as well.

services.AddAuthorization(options =>
        {
            options.AddPolicy(DefaultAuthorizedPolicy, policy =>
            {
                policy.Requirements.Add(new TokenAuthRequirement());
                policy.AuthenticationSchemes = new List<string>()
                                {
                                    CookieAuthenticationDefaults.AuthenticationScheme
                                }
            });
        });

Do take into consideration that by Default AuthenticationSchemes property uses a read only list. I think it would be better to implement that instead of List as well.

Here's a simple example:

public class ObservableClass
{
    private Int32 _Value;

    public Int32 Value
    {
        get { return _Value; }
        set
        {
            if (_Value != value)
            {
                _Value = value;
                OnValueChanged();
            }
        }
    }

    public event EventHandler ValueChanged;

    protected void OnValueChanged()
    {
        if (ValueChanged != null)
            ValueChanged(this, EventArgs.Empty);
    }
}

public class ObserverClass
{
    public ObserverClass(ObservableClass observable)
    {
        observable.ValueChanged += TheValueChanged;
    }

    private void TheValueChanged(Object sender, EventArgs e)
    {
        Console.Out.WriteLine("Value changed to " +
            ((ObservableClass)sender).Value);
    }
}

public class Program
{
    public static void Main()
    {
        ObservableClass observable = new ObservableClass();
        ObserverClass observer = new ObserverClass(observable);
        observable.Value = 10;
    }
}

Note:

• This violates a rule in that I don't unhook the observer from the observable, this is perhaps good enough for this simple example, but make sure you don't keep observers hanging off of your events like that. A way to handle this would be to make ObserverClass IDisposable, and let the .Dispose method do the opposite of the code in the constructor
• No error-checking performed, at least a null-check should be done in the constructor of the ObserverClass

Download it from here and extract LatoOFL.rar then go to TTF and open this font-face-generator click at Choose File choose font which you want to use and click at generate then download it and then go html file open it and you see the code like this

@font-face {
        font-family: "Lato Black";
        src: url('698242188-Lato-Bla.eot');
        src: url('698242188-Lato-Bla.eot?#iefix') format('embedded-opentype'),
        url('698242188-Lato-Bla.svg#Lato Black') format('svg'),
        url('698242188-Lato-Bla.woff') format('woff'),
        url('698242188-Lato-Bla.ttf') format('truetype');
        font-weight: normal;
        font-style: normal;
}
body{
    font-family: "Lato Black";
    direction: ltr;
}

change the src code and give the url where your this font directory placed, now you can use it at your website...

If you don't want to download it use this

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

Just write this query in your db phpmyadmin.

ALTER TABLE TableName ADD UNIQUE (FieldName)

Eg: ALTER TABLE user ADD UNIQUE (email)

Depending on your workflow, this may be the kind of thing that you need rarely enough that there's little point in trying to figure out a command-line solution (unless you happen to be working without a graphical interface for some reason).

Just use one of the GUI-based tools that support index management, for example:

• git gui <-- uses the Tk windowing framework -- similar style to gitk
• git cola <-- a more modern-style GUI interface

These let you move files in and out of the index by point-and-click. They even have support for selecting and moving portions of a file (individual changes) to and from the index.

How about a different perspective: If you mess up while using one of the suggested, rather cryptic, commands:

• git rm --cached [file]
• git reset HEAD <file>

...you stand a real chance of losing data -- or at least making it hard to find. Unless you really need to do this with very high frequency, using a GUI tool is likely to be safer.

Working without the index

Based on the comments and votes, I've come to realize that a lot of people use the index all the time. I don't. Here's how:

• Commit my entire working copy (the typical case): git commit -a
• Commit just a few files: git commit (list of files)
• Commit all but a few modified files: git commit -a then amend via git gui
• Graphically review all changes to working copy: git difftool --dir-diff --tool=meld

From a related SO question: Format a number with commas but without decimals in SQL Server 2008 R2?

SELECT CONVERT(varchar, CAST(1112 AS money), 1)

This was tested in SQL Server 2008 R2.

How about this one.

fields = Model._meta.fields

One (possibly small) issue I have noted with the solutions so far is that they all seem to require a function call to process the comparison. This means that the query engine will need to do a full table scan to seek the rows you are after - and be unable to use an index. If the table is not going to get particularly large, this probably won't have any adverse affects (and you can happily ignore this answer).

If, on the other hand, the table could get quite large, the performance of the query could suffer.

I know you stated that you do not wish to compare the date part - but is there an actual date being stored in the datetime column, or are you using it to store only the time? If the latter, you can use a simple comparison operator, and this will reduce both CPU usage, and allow the query engine to use statistics and indexes (if present) to optimise the query.

If, however, the datetime column is being used to store both the date and time of the event, this obviously won't work. In this case if you can modify the app and the table structure, separate the date and time into two separate datetime columns, or create a indexed view that selects all the (relevant) columns of the source table, and a further column that contains the time element you wish to search for (use any of the previous answers to compute this) - and alter the app to query the view instead.

By using to_string

print(df.Name.to_string(index=False))

Simplest answer is to put another condition '.xml' == strtolower(substr($file, -3)).

But I'd recommend using glob instead too.

In my case, turned out that you need to be logged as owner of device to properly accept the USB debugging.

Tried the "Disable and re-enable USB debugging on the phone" step but didn't get the RSA prompt on "normal" user, switched to owner and tried again and got it.

Option 1: Use a nullable DateTime?

Option 2: Use DateTime.MinValue

Personally, I'd prefer option 1.

try

$('#xxx').attr('disabled', true);

In Internet Explorer, there must be declared a <!DOCTYPE> for the :hover selector to work on other elements than the <a> element.

This is a two-step process:

1. you need to create a login to SQL Server for that user, based on its Windows account

   CREATE LOGIN [<domainName>\<loginName>] FROM WINDOWS;
   

2. you need to grant this login permission to access a database:

   USE (your database)
   CREATE USER (username) FOR LOGIN (your login name)
   

Once you have that user in your database, you can give it any rights you want, e.g. you could assign it the db_datareader database role to read all tables.

USE (your database)
EXEC sp_addrolemember 'db_datareader', '(your user name)'

Assume file is already created in the predefined directory with name "table.txt"

• 1) change the ownership for file :

  sudo chown username:username table.txt
  

• 2) change the mode of the file

  sudo chmod 777 table.txt
  

Now, try it should work!

SELECT MAX(ID) from bugs WHERE user=Me

Just use echo $(cd ../ && pwd) while working in the directory whose parent dir you want to find out. This chain also has the added benefit of not having trailing slashes.

Store your zipcodes as CHAR(5) instead of a numeric type, or have your application pad it with zeroes when you load it from the DB. A way to do it with PHP using sprintf():

echo sprintf("%05d", 205); // prints 00205
echo sprintf("%05d", 1492); // prints 01492

Or you could have MySQL pad it for you with LPAD():

SELECT LPAD(zip, 5, '0') as zipcode FROM table;

Here's a way to update and pad all rows:

ALTER TABLE `table` CHANGE `zip` `zip` CHAR(5); #changes type
UPDATE table SET `zip`=LPAD(`zip`, 5, '0'); #pads everything

i did with

"start": "nodemon --watch 'src/**/*.ts' --ignore 'src/**/*.spec.ts' --exec ts-node src/index.ts"

and yarn start.. ts-node not like 'ts-node'

They are:

• print only takes one parameter, while echo can have multiple parameters.
• print returns a value (1), so can be used as an expression.
• echo is slightly faster.

What ports is RabbitMQ using?

Default: 5672, the manual has the answer. It's defined in the RABBITMQ_NODE_PORT variable.

If you're using jQuery, you can use a library, such as jQuery BBQ: Back Button & Query Library.

...jQuery BBQ provides a full .deparam() method, along with both hash state management, and fragment / query string parse and merge utility methods.

Edit: Adding Deparam Example:

 var DeparamExample = function() {_x000D_
            var params = $.deparam.querystring();_x000D_
_x000D_
            //nameofparam is the name of a param from url_x000D_
            //code below will get param if ajax refresh with hash_x000D_
            if (typeof params.nameofparam == 'undefined') {_x000D_
                params = jQuery.deparam.fragment(window.location.href);_x000D_
            }_x000D_
            _x000D_
            if (typeof params.nameofparam != 'undefined') {_x000D_
                var paramValue = params.nameofparam.toString();_x000D_
                  _x000D_
            }_x000D_
        };

If you want to just use plain JavaScript, you could use...

var getParamValue = (function() {
    var params;
    var resetParams = function() {
            var query = window.location.search;
            var regex = /[?&;](.+?)=([^&;]+)/g;
            var match;

            params = {};

            if (query) {
                while (match = regex.exec(query)) {
                    params[match[1]] = decodeURIComponent(match[2]);
                }
            }    
        };

    window.addEventListener
    && window.addEventListener('popstate', resetParams);

    resetParams();

    return function(param) {
        return params.hasOwnProperty(param) ? params[param] : null;
    }

})();?

Because of the new HTML History API and specifically history.pushState() and history.replaceState(), the URL can change which will invalidate the cache of parameters and their values.

This version will update its internal cache of parameters each time the history changes.

Option 1. Using boost library, you can declare the string as below

const boost::string_view helpText = "This is very long help text.\n"
      "Also more text is here\n"
      "And here\n"

// Pass help text here
setHelpText(helpText);

Option 2. If boost is not available in your project, you can use std::string_view() in modern C++.

You need ImageMagick and GhostScript

<?php
$im = new imagick('file.pdf[0]');
$im->setImageFormat('jpg');
header('Content-Type: image/jpeg');
echo $im;
?>

The [0] means page 1.

Check out the Node js modules wiki page. They have listed all the templating engines supporting node.js.

I also faced a similar issue, in my case I had to set titles dynamically on each activity depending on the content.

So this worked for me.

actionBar.setTitle("  " + yourActivityTitle);

If all you want is the spacing, this is the easiest solution I could think of.

I got it because I wasn't using[self performSegueWithIdentifier:sender:] and -(void) prepareForSegue:(UIstoryboardSegue *) right

I have changed @Catch22's solution A bit as I do not like the idea of having to go into each field if I decide I want to change one of the colors. This is especially important in reports where the are numerous fields that would need to have the color variable changed.

'*************************************************************************
' -- Display alternate color banding (defined below) in detail rows
' -- Call from BackgroundColor property of all detail row textboxes
'*************************************************************************
Function AlternateColor(Byval rowNumber as integer) As String
    Dim OddColor As String = "Green"
    Dim EvenColor As String = "White"

    If rowNumber mod 2 = 0 then 
        Return EvenColor
    Else
        Return OddColor
    End If
End Function

Noticed that I have change the function from one that accepts the colors to one that contains the colors to be used.

Then in each field add:

=Code.AlternateColor(rownumber(nothing))

This is much more robust than manually changing the color in each fields' background color.

FILE_NAME = 'file.txt'

wordCounter = {}

with open(FILE_NAME,'r') as fh:
  for line in fh:
    # Replacing punctuation characters. Making the string to lower.
    # The split will spit the line into a list.
    word_list = line.replace(',','').replace('\'','').replace('.','').lower().split()
    for word in word_list:
      # Adding  the word into the wordCounter dictionary.
      if word not in wordCounter:
        wordCounter[word] = 1
      else:
        # if the word is already in the dictionary update its count.
        wordCounter[word] = wordCounter[word] + 1

print('{:15}{:3}'.format('Word','Count'))
print('-' * 18)

# printing the words and its occurrence.
for  (word,occurance)  in wordCounter.items(): 
  print('{:15}{:3}'.format(word,occurance))

Here's a flowchart based on this answer. See also, using script to emulate a terminal.

Using the base package:

df <- data.frame(days = c(88, 11, 2, 5, 22, 1, 222, 2), name = c("Lynn", "Tom", "Chris", "Lisa", "Kyla", "Tom", "Lynn", "Lynn"))

# Three lines
target <- c("Tom", "Lynn")
index <- df$name %in% target
df[index, ]

# One line
df[df$name %in% c("Tom", "Lynn"), ] 

Output:

  days name
1   88 Lynn
2   11  Tom
6    1  Tom
7  222 Lynn
8    2 Lynn

Using sqldf:

library(sqldf)
# Two alternatives:
sqldf('SELECT *
      FROM df 
      WHERE name = "Tom" OR name = "Lynn"')
sqldf('SELECT *
      FROM df 
      WHERE name IN ("Tom", "Lynn")')

Jinja 2.6 does not have the map function. So an alternate way of doing this would be:

set_fact: foo="{% for i in bar_result.results %}{{ i.ansible_facts.foo_item }}{%endfor%}"

Since Node.js v0.12 and as of Node.js v4.0.0, there is a stable readline core module. Here's the easiest way to read lines from a file, without any external modules:

const fs = require('fs');
const readline = require('readline');

async function processLineByLine() {
  const fileStream = fs.createReadStream('input.txt');

  const rl = readline.createInterface({
    input: fileStream,
    crlfDelay: Infinity
  });
  // Note: we use the crlfDelay option to recognize all instances of CR LF
  // ('\r\n') in input.txt as a single line break.

  for (const line of rl) {
    // Each line in input.txt will be successively available here as `line`.
    console.log(`Line from file: ${line}`);
  }
}

processLineByLine();

Or alternatively:

var lineReader = require('readline').createInterface({
  input: require('fs').createReadStream('file.in')
});

lineReader.on('line', function (line) {
  console.log('Line from file:', line);
});

The last line is read correctly (as of Node v0.12 or later), even if there is no final \n.

UPDATE: this example has been added to Node's API official documentation.

Actually this is possible but only with a Google Cloud API instead one from Firebase. It's because a Firebase Storage is a Google Cloud Storage Bucket which can be reached easily with the Google Cloud APIs however you need to use OAuth for Authentication instead of the Firebase one's.

For me I think there might be some issue in installing android NDK from android studio. I was able to resolve this in following manner

Downloaded android ndk from

https://developer.android.com/ndk/downloads/index.html

and placed inside ndk-bundle (where your android sdk is installed ). For more info check this screens.

https://app.box.com/s/dfi4h9k7v4h0tmbu3z9qnqx3d12fdejn

For debugging purposes, you can use the DLL file. You can run it using dotnet ConsoleApp2.dll. If you want to generate an EXE file, you have to generate a self-contained application.

To generate a self-contained application (EXE in Windows), you must specify the target runtime (which is specific to the operating system you target).

Pre-.NET Core 2.0 only: First, add the runtime identifier of the target runtimes in the .csproj file (list of supported RIDs):

<PropertyGroup>
    <RuntimeIdentifiers>win10-x64;ubuntu.16.10-x64</RuntimeIdentifiers>
</PropertyGroup>

The above step is no longer required starting with .NET Core 2.0.

Then, set the desired runtime when you publish your application:

dotnet publish -c Release -r win10-x64
dotnet publish -c Release -r ubuntu.16.10-x64

on MAC starting from chrome Version 67.0.3396.99 my self-signed certificate stopped to work.

regeneration with all what written here didn't work.

UPDATE

had a chance to confirm that my approach works today :). If it doesn't work for you make sure your are using this approach

v3.ext
authorityKeyIdentifier=keyid,issuer
basicConstraints=CA:FALSE
keyUsage = digitalSignature, nonRepudiation, keyEncipherment, dataEncipherment
subjectAltName = @alt_names

[alt_names]
DNS.1 = <specify-the-same-common-name-that-you-used-while-generating-csr-in-the-last-step>
$

copied from here https://ksearch.wordpress.com/2017/08/22/generate-and-import-a-self-signed-ssl-certificate-on-mac-osx-sierra/

END UPDATE

finally was able to see green Secure only when removed my cert from system, and added it to local keychain. (if there is one - drop it first). Not sure if it maters but in my case I downloaded certificate via chrome, and verified that create date is today - so it is the one I've just created.

hope it will be helpful for someone spend like a day on it.

never update chrome!

An important part of using a key down on tab is knowing that tab will always try to do something already, don't forget to "return false" at the end.

Here is what I did. I have a function that runs on .blur and a function that swaps where my form focus is. Basically it adds an input to the end of the form and goes there while running calculations on blur.

$(this).children('input[type=text]').blur(timeEntered).keydown(function (e) {
        var code = e.keyCode || e.which;
        if (code == "9") {
            window.tabPressed = true;
            // Here is the external function you want to call, let your external
            // function handle all your custom code, then return false to
            // prevent the tab button from doing whatever it would naturally do.
            focusShift($(this));
            return false;
        } else {
            window.tabPressed = false;
        }
        // This is the code i want to execute, it might be different than yours
        function focusShift(trigger) {
            var focalPoint = false;
            if (tabPressed == true) {
                console.log($(trigger).parents("td").next("td"));
                focalPoint = $(trigger).parents("td").next("td");

            }
            if (focalPoint) {
                $(focalPoint).trigger("click");
            }
        }
    });

This is very simple logic, So no need of regx.

Instead go for using ternary operator

var num = 89;
var isValid = (num <=  100 && num > 0 ) ? true : false;

It will do the magic for you!!

This is just an explanation not addressed in other answers

At least in recent versions of Mysql, your first query is not committed.

If you query it under the same session you will see the changes, but if you query it from a different session, the changes are not there, they are not committed.

What's going on?

When you open a transaction, and a query inside it fails, the transaction keeps open, it does not commit nor rollback the changes.

So BE CAREFUL, any table/row that was locked with a previous query likeSELECT ... FOR SHARE/UPDATE, UPDATE, INSERT or any other locking-query, keeps locked until that session is killed (and executes a rollback), or until a subsequent query commits it explicitly (COMMIT) or implicitly, thus making the partial changes permanent (which might happen hours later, while the transaction was in a waiting state).

That's why the solution involves declaring handlers to immediately ROLLBACK when an error happens.

Extra

Inside the handler you can also re-raise the error using RESIGNAL, otherwise the stored procedure executes "Successfully"

BEGIN
    DECLARE EXIT HANDLER FOR SQLEXCEPTION 
        BEGIN
            ROLLBACK;
            RESIGNAL;
        END;

    START TRANSACTION;
        #.. Query 1 ..
        #.. Query 2 ..
        #.. Query 3 ..
    COMMIT;
END

I tried this:

android:backgroundTint:"@color/mycolor"

instead of changing background property. This does not remove the material effect.

Here's a hack that seems to work in Firefox and Chrome.

In Firefox, having a disabled text field just before the password field seems to do the trick, even if it is hidden (disabled: none)

In Chrome, it has to be visible though.

So I suggest something like this :

HTML:

<input class="password-autocomplete-disabler" type="text" disabled>
<input type="password" name="pwd">

CSS :

input[type=text].password-autocomplete-disabler {
    position: absolute !important;
    left: -10000px !important;
    top: -10000px !important;
}

I have Windows 8.1, Eclipse Neon, Tomcat 8.

The solution is to copy all the files from folder ".../Tomcatxxx/conf" to the ".../Workspace_directory/Servers" and try to launch server again.

Add

<form target="_blank" ...></form>

or

form.setAttribute("target", "_blank");

to your form's definition.

You'd need to use either GET or POST information. GET would be simplest. Your JS would check the URL, if a certain param wasn't found, it wouldn't just refresh the page, but rather send the user to a "different" url, which would be the same URL but with the GET parameter in it.

For example:
http://example.com -->will refresh
http://example.com?refresh=no -->won't refresh

If you don't want the messy URL, then I'd include some PHP right at the beginning of the body that echos a hidden value that essentitally says whether the necessary POST param for not refreshing the page was included in the initial page request. Right after that, you'd include some JS to check that value and refresh the page WITH that POST information if necessary.

If you are working with numpy you can use

import numpy as np
np.abs(-1.23)
>> 1.23

It will provide absolute values.

A non-committed transaction can be reverted by issuing the command ROLLBACK

But if you are running in auto-commit mode there is nothing you can do....

same result as others, different style:

extension UIImage {

    func withAlpha(_ alpha: CGFloat) -> UIImage {
        return UIGraphicsImageRenderer(size: size).image { _ in
            draw(at: .zero, blendMode: .normal, alpha: alpha)
        }
    }

}

Just for fun, I found an interesting article here, to use a somehow hidden evaluate function that does exist in Excel. The trick is to assign it to a name, and use the name in your cells, because EVALUATE() would give you an error msg if used directly in a cell. I tried and it works! You can use it with a relative name, if you want to copy accross rows if a sheet.

Entity Framework performs something similar to gbn's answer:

DECLARE @generated_keys table([Id] uniqueidentifier)

INSERT INTO Customers(FirstName)
OUTPUT inserted.CustomerID INTO @generated_keys
VALUES('bob');

SELECT t.[CustomerID]
FROM @generated_keys AS g 
   JOIN dbo.Customers AS t 
   ON g.Id = t.CustomerID
WHERE @@ROWCOUNT > 0

The output results are stored in a temporary table variable, and then selected back to the client. Have to be aware of the gotcha:

inserts can generate more than one row, so the variable can hold more than one row, so you can be returned more than one ID

I have no idea why EF would inner join the ephemeral table back to the real table (under what circumstances would the two not match).

But that's what EF does.

SQL Server 2008 or newer only. If it's 2005 then you're out of luck.

You can use Location as mentioned here.

Here's my code if the link opened on new tab

navBack() {
    let cur_path = this.location.path();
    this.location.back();
    if (cur_path === this.location.path())
     this.router.navigate(['/default-route']);    
  }

Required imports

import { Router } from '@angular/router';
import { Location } from '@angular/common';

import * as express from "express";

This is the suggested way of doing it because it is the standard for JavaScript (ES6/2015) since last year.

In any case, in your tsconfig.json file, you should target the module option to commonjs which is the format supported by nodejs.

Just add a div around the container so it looks like:

<div style="background: red;">
  <div class="container marketing">
    <h2 style="padding-top: 60px;"></h2>
  </div>
</div>

var x : IHash = {};
x['key1'] = 'value1';
x['key2'] = 'value2';

console.log(x['key1']);
// outputs value1

console.log(x['key2']);
// outputs value2

If you would like to then iterate through your dictionary, you can use.

Object.keys(x).forEach((key) => {console.log(x[key])});

Object.keys returns all the properties of an object, so it works nicely for returning all the values from dictionary styled objects.

You also mentioned a hashmap in your question, the above definition is for a dictionary style interface. Therefore the keys will be unique, but the values will not.

You could use it like a hashset by just assigning the same value to the key and its value.

if you wanted the keys to be unique and with potentially different values, then you just have to check if the key exists on the object before adding to it.

var valueToAdd = 'one';
if(!x[valueToAdd])
   x[valueToAdd] = valueToAdd;

or you could build your own class to act as a hashset of sorts.

Class HashSet{
  private var keys: IHash = {};
  private var values: string[] = [];

  public Add(key: string){
    if(!keys[key]){
      values.push(key);
      keys[key] = key;
    }
  }

  public GetValues(){
    // slicing the array will return it by value so users cannot accidentally
    // start playing around with your array
    return values.slice();
  }
}

As an addition to Frank Heiken's answer, if you wish to use INSERT statements instead of copy from stdin, then you should specify the --inserts flag

pg_dump --host localhost --port 5432 --username postgres --format plain --verbose --file "<abstract_file_path>" --table public.tablename --inserts dbname

Notice that I left out the --ignore-version flag, because it is deprecated.

There is another way to pass arguments to CreateInstance through named parameters.

Based on that, you can pass a array towards CreateInstance. This will allow you to have 0 or multiple arguments.

public T CreateInstance<T>(params object[] paramArray)
{
  return (T)Activator.CreateInstance(typeof(T), args:paramArray);
}

This will display a list of the full path to each file that contains the search string:

foreach ($file in Get-ChildItem | Select-String -pattern "dummy" | Select-Object -Unique path) {$file.path}

Note that it doesn't display a header above the results and doesn't display the lines of text containing the search string. All it tells you is where you can find the files that contain the string.

To avoid confusion, paraphrasing both question and answer. I am assuming that user who posted this question wanted to save dictionary type object in JSON file format but when the user used json.dump, this method dumped all its content in one line. Instead, he wanted to record each dictionary entry on a new line. To achieve this use:

with g as outfile:
  json.dump(hostDict, outfile,indent=2)

Using indent = 2 helped me to dump each dictionary entry on a new line. Thank you @agf. Rewriting this answer to avoid confusion.

Here's how you get the image size from the given URL in Python 3:

from PIL import Image
import urllib.request
from io import BytesIO

file = BytesIO(urllib.request.urlopen('http://getwallpapers.com/wallpaper/full/b/8/d/32803.jpg').read())
im = Image.open(file)
width, height = im.size

You might be able to solve this simply by renaming your test class to have a name that ends with Test, e.g. ThisAndThatTest

The behavior of host objects <object> is due to ECMA262 implementation dependent and set attribute by setAttribute() method may fail.

I see two solutions:

1. soft: element.data = "http://www.google.com";

2. hard: remove object from DOM tree and create new one with changed data attribute.

body has default margins: http://www.w3.org/TR/CSS2/sample.html

body { margin:0; } /* Remove body margins */

Or you could use this useful Global reset

If you want something less * global than:

html, body, body div, span, object, iframe, h1, h2, h3, h4, h5, h6, p, blockquote, pre, abbr, address, cite, code, del, dfn, em, img, ins, kbd, q, samp, small, strong, sub, sup, var, b, i, dl, dt, dd, ol, ul, li, fieldset, form, label, legend, table, caption, tbody, tfoot, thead, tr, th, td, article, aside, figure, footer, header, hgroup, menu, nav, section, time, mark, audio, video {
    margin: 0;
    padding: 0;
    border: 0;
    outline: 0;

The initialize method is called after all @FXML annotated members have been injected. Suppose you have a table view you want to populate with data:

class MyController { 
    @FXML
    TableView<MyModel> tableView; 

    public MyController() {
        tableView.getItems().addAll(getDataFromSource()); // results in NullPointerException, as tableView is null at this point. 
    }

    @FXML
    public void initialize() {
        tableView.getItems().addAll(getDataFromSource()); // Perfectly Ok here, as FXMLLoader already populated all @FXML annotated members. 
    }
}

JpaRepository extends PagingAndSortingRepository which in turn extends CrudRepository.

Their main functions are:

• CrudRepository mainly provides CRUD functions.
• PagingAndSortingRepository provides methods to do pagination and sorting records.
• JpaRepository provides some JPA-related methods such as flushing the persistence context and deleting records in a batch.

Because of the inheritance mentioned above, JpaRepository will have all the functions of CrudRepository and PagingAndSortingRepository. So if you don't need the repository to have the functions provided by JpaRepository and PagingAndSortingRepository , use CrudRepository.

$("#date").datepicker('getDate').getMonth() + 1; 

The month on the datepicker is 0 based (0-11), so add 1 to get the month as it appears in the date.

Note for zsh users: replace all references to ~/.bash_profile with ~/.zshrc.

Option 1 - Using Homebrew

This is the easiest way and will provide automatic updates.

1. Install the homebrew package manager

    /bin/bash -c "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install.sh)"
   

2. Install adb

    brew install android-platform-tools
   

3. Start using adb

    adb devices
   

Option 2 - Manually (just the platform tools)

This is the easiest way to get a manual installation of ADB and Fastboot.

1. Delete your old installation (optional)

    rm -rf ~/.android-sdk-macosx/
   

2. Navigate to https://developer.android.com/studio/releases/platform-tools.html and click on the SDK Platform-Tools for Mac link.

3. Go to your Downloads folder

    cd ~/Downloads/
   

4. Unzip the tools you downloaded

    unzip platform-tools-latest*.zip 
   

5. Move them somewhere you won't accidentally delete them

    mkdir ~/.android-sdk-macosx
    mv platform-tools/ ~/.android-sdk-macosx/platform-tools
   

6. Add platform-tools to your path

    echo 'export PATH=$PATH:~/.android-sdk-macosx/platform-tools/' >> ~/.bash_profile
   

7. Refresh your bash profile (or restart your terminal app)

    source ~/.bash_profile
   

8. Start using adb

    adb devices
   

Option 3 - Manually (with SDK Manager)

1. Delete your old installation (optional)

    rm -rf ~/.android-sdk-macosx/
   

2. Download the Mac SDK Tools from the Android developer site under "Get just the command line tools". Make sure you save them to your Downloads folder.

3. Go to your Downloads folder

    cd ~/Downloads/
   

4. Unzip the tools you downloaded

    unzip tools_r*-macosx.zip 
   

5. Move them somewhere you won't accidentally delete them

    mkdir ~/.android-sdk-macosx
    mv tools/ ~/.android-sdk-macosx/tools
   

6. Run the SDK Manager

    sh ~/.android-sdk-macosx/tools/android
   

7. Uncheck everything but Android SDK Platform-tools (optional)

8. Click Install Packages, accept licenses, click Install. Close the SDK Manager window.

9. Add platform-tools to your path

    echo 'export PATH=$PATH:~/.android-sdk-macosx/platform-tools/' >> ~/.bash_profile
   

10. Refresh your bash profile (or restart your terminal app)

    source ~/.bash_profile
    

11. Start using adb

    adb devices
    

Just ran into this issue - if you updated a bunch of files and don't want to do git mv all of them this also works:

1. Rename parent directory from /dir/RenamedFile.js to /whatever/RenamedFile.js.
2. git add -A to stage that change
3. Rename parent directory back to /dir/RenamedFile.js.
4. git add -A again, will re-stage vs that change, forcing git to pick up the filename change.

Try this JQuery code to dynamically include form, field, and delete/remove behavior:

$(document).ready(function() {_x000D_
    var max_fields = 10;_x000D_
    var wrapper = $(".container1");_x000D_
    var add_button = $(".add_form_field");_x000D_
_x000D_
    var x = 1;_x000D_
    $(add_button).click(function(e) {_x000D_
        e.preventDefault();_x000D_
        if (x < max_fields) {_x000D_
            x++;_x000D_
            $(wrapper).append('<div><input type="text" name="mytext[]"/><a href="#" class="delete">Delete</a></div>'); //add input box_x000D_
        } else {_x000D_
            alert('You Reached the limits')_x000D_
        }_x000D_
    });_x000D_

        $(this).parent('div').remove();_x000D_
        x--;_x000D_
    })_x000D_
});

The accepted answer has to load the whole file into memory, which doesn't work nicely for large files. The following solution writes the file contents with the new data inserted into the right line to a temporary file in the same directory (so on the same file system), only reading small chunks from the source file at a time. It then overwrites the source file with the contents of the temporary file in an efficient way (Python 3.8+).

from pathlib import Path
from shutil import copyfile
from tempfile import NamedTemporaryFile

sourcefile = Path("/path/to/source").resolve()
insert_lineno = 152  # The line to insert the new data into.
insert_data = "..."  # Some string to insert.

with sourcefile.open(mode="r") as source:
    destination = NamedTemporaryFile(mode="w", dir=str(sourcefile.parent))
    lineno = 1

    while lineno < insert_lineno:
        destination.file.write(source.readline())
        lineno += 1

    # Insert the new data.
    destination.file.write(insert_data)

    # Write the rest in chunks.
    while True:
        data = source.read(1024)
        if not data:
            break
        destination.file.write(data)

# Finish writing data.
destination.flush()
# Overwrite the original file's contents with that of the temporary file.
# This uses a memory-optimised copy operation starting from Python 3.8.
copyfile(destination.name, str(sourcefile))
# Delete the temporary file.
destination.close()

EDIT 2020-09-08: I just found an answer on Code Review that does something similar to above with more explanation - it might be useful to some.

You could try a formatter like this

They will always be limited because they don't (and can't) know what user defined functions you may have defined in your database (or which built-in functions you have or don't have access to).

You could also look at ANTLR (but that would be an offline solution)

Run

locate pip3

it should give you a list of results like this

/<path>/pip3
/<path>/pip3.x

go to /usr/local/bin to make a symbolic link to where your pip3 is located

ln -s /<path>/pip3.x /usr/local/bin/pip3

It is always a good coding practice to make your one argument constructors (including those with default values for arg2,arg3,...) as already stated. Like always with C++: if you don't - you'll wish you did...

Another good practice for classes is to make copy construction and assignment private (a.k.a. disable it) unless you really need to implement it. This avoids having eventual copies of pointers when using the methods that C++ will create for you by default. An other way to do this is derive from boost::noncopyable.

Since you are not interested in keeping any data, drop the entire database and create a new one.

Have you tried?

mWebView.setDownloadListener(new DownloadListener() {
    public void onDownloadStart(String url, String userAgent,
                String contentDisposition, String mimetype,
                long contentLength) {
        Intent i = new Intent(Intent.ACTION_VIEW);
        i.setData(Uri.parse(url));
        startActivity(i);
    }
});

This is possible using this cross browser javascript implementation of the HTML5 saveAs function: https://github.com/koffsyrup/FileSaver.js

If all you want to do is save text then the above script works in all browsers(including all versions of IE), using nothing but JS.

You can use a css3 psuedo element (:before and/or :after) as shown in this article

https://www.exratione.com/2011/09/how-to-overflow-a-background-image-using-css3/

Good Luck...

is is identity testing, == is equality testing. what happens in your code would be emulated in the interpreter like this:

>>> a = 'pub'
>>> b = ''.join(['p', 'u', 'b'])
>>> a == b
True
>>> a is b
False

so, no wonder they're not the same, right?

In other words: a is b is the equivalent of id(a) == id(b)

When you reference Range like that it's called an unqualified reference because you don't specifically say which sheet the range is on. Unqualified references are handled by the "_Global" object that determines which object you're referring to and that depends on where your code is.

If you're in a standard module, unqualified Range will refer to Activesheet. If you're in a sheet's class module, unqualified Range will refer to that sheet.

inputTemplateContent is a variable that contains a reference to a range, probably a named range. If you look at the RefersTo property of that named range, it likely points to a sheet other than the Activesheet at the time the code executes.

The best way to fix this is to avoid unqualified Range references by specifying the sheet. Like

With ThisWorkbook.Worksheets("Template")
    .Range(inputTemplateHeader).Value = NO_ENTRY
    .Range(inputTemplateContent).Value = NO_ENTRY
End With

Adjust the workbook and worksheet references to fit your particular situation.

Imagine a stack of paper. The last piece put into the stack is on the top, so it is the first one to come out. This is LIFO. Adding a piece of paper is called "pushing", and removing a piece of paper is called "popping".

Imagine a queue at the store. The first person in line is the first person to get out of line. This is FIFO. A person getting into line is "enqueued", and a person getting out of line is "dequeued".

@scanlegentil I like this.
A little improvement would be:

$Depth = 2
$Path = "."

$Levels = "\*" * $Depth
$Folder = Get-Item $Path
$FolderFullName = $Folder.FullName
Resolve-Path $FolderFullName$Levels | Get-Item | ? {$_.PsIsContainer} | Write-Host

As mentioned, this would only scan the specified depth, so this modification is an improvement:

$StartLevel = 1 # 0 = include base folder, 1 = sub-folders only, 2 = start at 2nd level
$Depth = 2      # How many levels deep to scan
$Path = "."     # starting path

For ($i=$StartLevel; $i -le $Depth; $i++) {
    $Levels = "\*" * $i
    (Resolve-Path $Path$Levels).ProviderPath | Get-Item | Where PsIsContainer |
    Select FullName
}

I directly used the following command from my Mac using the terminal. I got SHA1 Finger. This is the command:

keytool -list -v -keystore ~/.android/debug.keystore -alias androiddebugkey -storepass android -keypass android

I just had a problem like this. My particular problem was caused by a system crash that corrupted the most recent commit (and hence also the master branch). I hadn't pushed, and wanted to re-make that commit. In my particular case, I was able to deal with it like this:

1. Make a backup of .git/: rsync -a .git/ git-bak/
2. Check .git/logs/HEAD, and find the last line with a valid commit ID. For me, this was the second most recent commit. This was good, because I still had the working directory versions of the file, and so the every version I wanted.
3. Make a branch at that commit: git branch temp <commit-id>
4. re-do the broken commit with the files in the working directory.
5. git reset master temp to move the master branch to the new commit you made in step 2.
6. git checkout master and check that it looks right with git log.
7. git branch -d temp.
8. git fsck --full, and it should now be safe to delete any corrupted objects that fsck finds.
9. If it all looks good, try pushing. If that works,

That worked for for me. I suspect that this is a reasonably common scenario, since the most recent commit is the most likely one to be corrupted, but if you lose one further back, you can probably still use a method like this, with careful use of git cherrypick, and the reflog in .git/logs/HEAD.

net stop MySQL*

or

mysqld stop

or

mysql stop

in the window's command line prompt.

<*> if you're using windows XP, you need the name of your service, which can be obtained doing this: (credits @Atli)

right click the "My Computer" shortcut in the Start menu, select "Manage", click "Services" in the "Services and applications" group. And then search the list of services until you find the MySQL service.

Then you can start [or stop] the service by using that name. It is can sometimes be called "mysql5" or "mysql51", or something like that. Depends on who installed it.

This violates DRY principle, but it's a concise solution:

var button = '<a href="{link}" class="btn">{text}</a>';
button = button.replace('{text}','Authorize on GitHub').replace('{link}', authorizeUrl);

3D case

Modifying Mohsen's answer for 3D array:

[M,I] = max (A(:));
[ind1, ind2, ind3] = ind2sub(size(A),I)

Another cause of "TCP ACKed Unseen" is the number of packets that may get dropped in a capture. If I run an unfiltered capture for all traffic on a busy interface, I will sometimes see a large number of 'dropped' packets after stopping tshark.

On the last capture I did when I saw this, I had 2893204 packets captured, but once I hit Ctrl-C, I got a 87581 packets dropped message. Thats a 3% loss, so when wireshark opens the capture, its likely to be missing packets and report "unseen" packets.

As I mentioned, I captured a really busy interface with no capture filter, so tshark had to sort all packets, when I use a capture filter to remove some of the noise, I no longer get the error.

The then() method returns a Promise. It takes two arguments, both are callback functions for the success and failure cases of the Promise. the promise object itself doesn't give you the resolved data directly, the interface of this object only provides the data via callbacks supplied. So, you have to do this like this:

getFeed().then(function(data) { vm.feed = data;});

The then() function returns the promise with a resolved value of the previous then() callback, allowing you the pass the value to subsequent callbacks:

promiseB = promiseA.then(function(result) {
  return result + 1;
});

// promiseB will be resolved immediately after promiseA is resolved
// and its value will be the result of promiseA incremented by 1

In the Developer Tools in Chrome, there is a bar along the top, called the Execution Context Selector (h/t felipe-sabino), just under the Elements, Network, Sources... tabs, that changes depending on the context of the current tab. When in the Console tab there is a dropdown in that bar that allows you to select the frame context in which the Console will operate. Select your frame in this drop down and you will find yourself in the appropriate frame context. :D

I modified Neutrino's solution to make the xaml look less verbose when specifying the value:

Sorry for no pictures of the rendered xaml, just imagine a [=] hamburger button that you click and it turns into [<-] a back button and also toggles the visibility of a Grid.

xmlns:i="clr-namespace:System.Windows.Interactivity;assembly=System.Windows.Interactivity"

...

<Grid>
    <Button x:Name="optionsButton">
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="Click">
                <local:SetterAction PropertyName="Visibility" Value="Collapsed" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsBackButton}" Value="Visible" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsPanel}" Value="Visible" />
            </i:EventTrigger>
        </i:Interaction.Triggers>

        <glyphs:Hamburger Width="10" Height="10" />
    </Button>

    <Button x:Name="optionsBackButton" Visibility="Collapsed">
        <i:Interaction.Triggers>
            <i:EventTrigger EventName="Click">
                <local:SetterAction PropertyName="Visibility" Value="Collapsed" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsButton}" Value="Visible" />
                <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsPanel}" Value="Collapsed" />
            </i:EventTrigger>
        </i:Interaction.Triggers>

        <glyphs:Back Width="12" Height="11" />
    </Button>
</Grid>

...

<Grid Grid.RowSpan="2" x:Name="optionsPanel" Visibility="Collapsed">

</Grid>

You can also specify values this way like in Neutrino's solution:

<Button x:Name="optionsButton">
    <i:Interaction.Triggers>
        <i:EventTrigger EventName="Click">
            <local:SetterAction PropertyName="Visibility" Value="{x:Static Visibility.Collapsed}" />
            <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsBackButton}" Value="{x:Static Visibility.Visible}" />
            <local:SetterAction PropertyName="Visibility" TargetObject="{Binding ElementName=optionsPanel}" Value="{x:Static Visibility.Visible}" />
        </i:EventTrigger>
    </i:Interaction.Triggers>

    <glyphs:Hamburger Width="10" Height="10" />
</Button>

For anyone else getting

Nginx 403 error: directory index of [folder] is forbidden

when using index.php while index.html works perfectly and having included index.php in the index in the server block of their site config in sites-enabled

Make sure your nginx.conf file at /etc/nginx/nginx.conf actually loads your site config in the http block...

psql -U postgres

Worked fine for me in case of db name: postgres & username: postgres. So you do not need to write sudo.

And in the case other db, you may try

psql -U yourdb postgres

As it is given in Postgres help:

psql [OPTION]... [DBNAME [USERNAME]]

There is no simple way to achieves this directly. But P99 has macros that allow you to create such type of function automatically:

 P99_DECLARE_ENUM(color, red, green, blue);

in a header file, and

 P99_DEFINE_ENUM(color);

in one compilation unit (.c file) should then do the trick, in that example the function then would be called color_getname.

I had a simular issue and resolved it using android:adjustViewBounds="true" on the ImageView.

<ImageView
    android:layout_width="fill_parent"

    android:contentDescription="@string/banner_alt"

In the numpy README.txt file, it says

After installation, tests can be run with:

python -c 'import numpy; numpy.test()'

This should be a sufficient test for proper installation.

A good answer to this question should be succinct, handle unicode correctly, and deal with empty strings and nulls.

function isUpperCase(c) {
    return !!c && c != c.toLocaleLowerCase();
}

This approach deals with empty strings and nulls first, then ensures that converting the given string to lower case changes its equality. This ensures that the string contains at least one capital letter according to the current local's capitalisation rules (and won't return false positives for numbers and other glyphs that don't have capitalisation).

The original question asked specifically about testing the first character. In order to keep your code simple and clear I'd split the first character off the string separately from testing whether it's upper case.

I have encountered with same issue. When I changed content type it has solved. I'm not sure this solution will help you but maybe it is. If you don't mind about content-type, it worked for me.

axios.defaults.headers.post['Content-Type'] ='application/x-www-form-urlencoded';

In addition to Ctrl+Shift+F (Cmd+Option+F on Mac) as suggested in this answer, you can right click on the top tree node in the sources tab and select "Search in All Files":

Or maybe

You forgot to add std:: namespace prefix to vector class name.

Edit: Thanks Marc, read up on the struct vs class issue and you're right, thank you!

I tend to use the following method for doing what you describe, using a static method of JSon.Net:

MyObject deserializedObject = JsonConvert.DeserializeObject<MyObject>(json);

Link: Serializing and Deserializing JSON with Json.NET

For the Objects list, may I suggest using generic lists out made out of your own small class containing attributes and position class. You can use the Point struct in System.Drawing (System.Drawing.Point or System.Drawing.PointF for floating point numbers) for you X and Y.

After object creation it's much easier to get the data you're after vs. the text parsing you're otherwise looking at.

Now I need to connect that application from my local computer, but I don't know the JMX port number of the remote computer. Where can I find it? Or, must I restart that application with some VM parameters to specify the port number?

By default JMX does not publish on a port unless you specify the arguments from this page: How to activate JMX...

-Dcom.sun.management.jmxremote # no longer required for JDK6
-Dcom.sun.management.jmxremote.port=9010
-Dcom.sun.management.jmxremote.local.only=false # careful with security implications
-Dcom.sun.management.jmxremote.authenticate=false # careful with security implications

If you are running you should be able to access any of those system properties to see if they have been set:

if (System.getProperty("com.sun.management.jmxremote") == null) {
    System.out.println("JMX remote is disabled");
} else [
    String portString = System.getProperty("com.sun.management.jmxremote.port");
    if (portString != null) {
        System.out.println("JMX running on port "
            + Integer.parseInt(portString));
    }
}

Depending on how the server is connected, you might also have to specify the following parameter. As part of the initial JMX connection, jconsole connects up to the RMI port to determine which port the JMX server is running on. When you initially start up a JMX enabled application, it looks its own hostname to determine what address to return in that initial RMI transaction. If your hostname is not in /etc/hosts or if it is set to an incorrect interface address then you can override it with the following:

-Djava.rmi.server.hostname=<IP address>

As an aside, my SimpleJMX package allows you to define both the JMX server and the RMI port or set them both to the same port. The above port defined with com.sun.management.jmxremote.port is actually the RMI port. This tells the client what port the JMX server is running on.

In your yaml file, add command and args lines:

...
containers:
      - name: api
        image: localhost:5000/image-name 
        command: [ "sleep" ]
        args: [ "infinity" ]
...

Works for me.

Easily done in Bootstrap 3 like so:

This is directly from http://www.programcreek.com/2011/10/java-class-instance-initializers/

1. Execution Order

Look at the following class, do you know which one gets executed first?

public class Foo {
 
    //instance variable initializer
    String s = "abc";
 
    //constructor
    public Foo() {
        System.out.println("constructor called");
    }
 
    //static initializer
    static {
        System.out.println("static initializer called");
    }
 
    //instance initializer
    {
        System.out.println("instance initializer called");
    }
 
    public static void main(String[] args) {
        new Foo();
        new Foo();
    }
}

Output:

static initializer called

instance initializer called

constructor called

instance initializer called

constructor called

2. How do Java instance initializer work?

The instance initializer above contains a println statement. To understand how it works, we can treat it as a variable assignment statement, e.g., b = 0. This can make it more obvious to understand.

Instead of

int b = 0, you could write

int b;
b = 0;

Therefore, instance initializers and instance variable initializers are pretty much the same.

3. When are instance initializers useful?

The use of instance initializers are rare, but still it can be a useful alternative to instance variable initializers if:

1. Initializer code must handle exceptions
2. Perform calculations that can’t be expressed with an instance variable initializer.

Of course, such code could be written in constructors. But if a class had multiple constructors, you would have to repeat the code in each constructor.

With an instance initializer, you can just write the code once, and it will be executed no matter what constructor is used to create the object. (I guess this is just a concept, and it is not used often.)

Another case in which instance initializers are useful is anonymous inner classes, which can’t declare any constructors at all. (Will this be a good place to place a logging function?)

Thanks to Derhein.

Also note that Anonymous classes that implement interfaces [1] have no constructors. Therefore instance initializers are needed to execute any kinds of expressions at construction time.

German Variant, but could be adapted to Iso

export function isLeapYear(year) {
  return (
    year % 4 === 0 && (year % 100 != 0 || year % 1000 === 0 || year % 400 === 0)
  )
}

export function isValidGermanDate(germanDate) {
  if (
    !germanDate ||
    germanDate.length < 5 ||
    germanDate.split('.').length < 3
  ) {
    return false
  }

  const day = parseInt(germanDate.split('.')[0])
  const month = parseInt(germanDate.split('.')[1])
  const year = parseInt(germanDate.split('.')[2])

  if (isNaN(month) || isNaN(day) || isNaN(year)) {
    return false
  }

  if (month < 1 || month > 12) {
    return false
  }

  if (day < 1 || day > 31) {
    return false
  }

  if ((month === 4 || month === 6 || month === 9 || month === 11) && day > 30) {
    return false
  }

  if (isLeapYear(year)) {
    if (month === 2 && day > 29) {
      return false
    }
  } else {
    if (month === 2 && day > 28) {
      return false
    }
  }

  return true
}

I think you can use this code also: and you can manage your class css better

<style>
   .navigationClass{
        display: inline-block;
        padding: 0px 0px 0px 6px;
        background-color: whitesmoke;
        border-radius: 2px;
    }
</style>
<div id="header" class="row">
    <div id="logo" class="col_12">And the winner is<span>n't...</span></div> 
    <div id="navigation" class="row"> 
        <ul id="pirra">
            <li><a href="#">Why?</a></li>
            <li><a href="#">Synopsis</a></li>
            <li><a href="#">Stills/Photos</a></li>
            <li><a href="#">Videos/clips</a></li>
            <li><a href="#">Quotes</a></li>
            <li><a href="#">Quiz</a></li>
        </ul>
    </div>
 <script>
    $(document).ready(function() {
$('#navigation ul li').addClass('navigationClass'); //add class navigationClass to the #navigation .

});
 </script>

Take a look at http://www.codeplex.com/json/ for the json-net.aspx project. Why re-invent the wheel?

The params object is included in $stateParams, but won't be part of the url.

1) In the route configuration:

$stateProvider.state('edit_user', {
    url: '/users/:user_id/edit',
    templateUrl: 'views/editUser.html',
    controller: 'editUserCtrl',
    params: {
        paramOne: { objectProperty: "defaultValueOne" },  //default value
        paramTwo: "defaultValueTwo"
    }
});

2) In the controller:

.controller('editUserCtrl', function ($stateParams, $scope) {       
    $scope.paramOne = $stateParams.paramOne;
    $scope.paramTwo = $stateParams.paramTwo;
});

3A) Changing the State from a controller

$state.go("edit_user", {
    user_id: 1,                
    paramOne: { objectProperty: "test_not_default1" },
    paramTwo: "from controller"
});

3B) Changing the State in html

<div ui-sref="edit_user({ user_id: 3, paramOne: { objectProperty: 'from_html1' }, paramTwo: 'fromhtml2' })"></div>

Example Plunker

Step 1:

git fetch origin

Step 2:

git rebase origin/master

Step 3:(Fix if any conflicts)

git add .

Step 4:

git rebase --continue

Step 5:

git push --force

Hopes this makes it find the tables as you're reading through the thing:

In addition to the answer of Dyppl, I think it would be nice to place this inside the OnDataContextChanged event:

private void OnDataContextChanged(object sender, DependencyPropertyChangedEventArgs e)
{
    // Unforunately we cannot bind from the viewmodel to the code behind so easily, the dependency property is not available in XAML. (for some reason).
    // To work around this, we create the binding once we get the viewmodel through the datacontext.
    var newViewModel = e.NewValue as MyViewModel;

    var executablePathBinding = new Binding
    {
        Source = newViewModel,
        Path = new PropertyPath(nameof(newViewModel.ExecutablePath))
    };

    BindingOperations.SetBinding(LayoutRoot, ExecutablePathProperty, executablePathBinding);
}

We have also had cases were we just saved the DataContext to a local property and used that to access viewmodel properties. The choice is of course yours, I like this approach because it is more consistent with the rest. You can also add some validation, like null checks. If you actually change your DataContext around, I think it would be nice to also call:

BindingOperations.ClearBinding(myText, TextBlock.TextProperty);

to clear the binding of the old viewmodel (e.oldValue in the event handler).

You can use:

File.WriteAllBytes("Foo.txt", arrBytes); // Requires System.IO

If you have an enumerable and not an array, you can use:

File.WriteAllBytes("Foo.txt", arrBytes.ToArray()); // Requires System.Linq

Simple solution: IN ~/.sdkman/etc/config, change sdkman_insecure_ssl=true

Steps:
nano ~/.sdkman/etc/config
change sdkman_insecure_ssl=false to sdkman_insecure_ssl=true
save and exit

there are 3 ways to do it.

1.Add the following line on style.xml to change entire application

<item name="android:textAllCaps">false</item>

2.Use

android:textAllCaps="false"

in your layout-v21

mButton.setTransformationMethod(null);

3. add this line under the element(button or edit text) in xml

android:textAllCaps="false"

Just open your project urls.py, then find this if statement.

if settings.DEBUG:
    urlpatterns += patterns(
        'django.views.static',
        (r'^media/(?P<path>.*)','serve',{'document_root': settings.MEDIA_ROOT}), )

You can change settings.DEBUG on True and it will work always. But if your project is a something serious then you should to think about other solutions mentioned above.

if True:
    urlpatterns += patterns(
        'django.views.static',
        (r'^media/(?P<path>.*)','serve',{'document_root': settings.MEDIA_ROOT}), )

In django 1.10 you can write so:

urlpatterns += [ url(r'^media/(?P<path>.*)$', serve, { 'document_root': settings.MEDIA_ROOT, }), url(r'^static/(?P<path>.*)$', serve, { 'document_root': settings.STATIC_ROOT }), ]

No, it is not to access every method, it is a "resolution" operator, that is, you use it to resolve the scope (or location you can say) of a constant/static symbol.

For example in the first of your line, Rails use it to find the Base class inside the ActiveRecord.Module, in your second one it is used to locate the class method (static) of the Routes class, etc, etc.

It is not used to expose anything, its used to "locate" stuff around your scopes.

             demo.innerHTML =document.write='<h1>Hello member</h1>';

In case of WSS 3.0 recently I experienced same issue. It was because of column that was accessed from code was not present in the wss list.

I got this error because the python script I was trying to submit was called pyspark.py (facepalm). The fix was to set my PYTHONPATH as recommended above, then rename the script to pyspark_test.py and clean up the pyspark.pyc that was created based on my scripts original name and that cleared this error up.

I Found this the most useful and easy to use https://wiki.python.org/moin/ConfigParserExamples

You just create a "myfile.ini" like:

[SectionOne]
Status: Single
Name: Derek
Value: Yes
Age: 30
Single: True

[SectionTwo]
FavoriteColor=Green
[SectionThree]
FamilyName: Johnson

[Others]
Route: 66

And retrieve the data like:

>>> import ConfigParser
>>> Config = ConfigParser.ConfigParser()
>>> Config
<ConfigParser.ConfigParser instance at 0x00BA9B20>
>>> Config.read("myfile.ini")
['c:\\tomorrow.ini']
>>> Config.sections()
['Others', 'SectionThree', 'SectionOne', 'SectionTwo']
>>> Config.options('SectionOne')
['Status', 'Name', 'Value', 'Age', 'Single']
>>> Config.get('SectionOne', 'Status')
'Single'

As of May 2017, multiple FROMs can be used in a single Dockerfile.
See "Builder pattern vs. Multi-stage builds in Docker" (by Alex Ellis) and PR 31257 by Tõnis Tiigi.

The general syntax involves adding FROM additional times within your Dockerfile - whichever is the last FROM statement is the final base image. To copy artifacts and outputs from intermediate images use COPY --from=<base_image_number>.

FROM golang:1.7.3 as builder
WORKDIR /go/src/github.com/alexellis/href-counter/
RUN go get -d -v golang.org/x/net/html  
COPY app.go    .
RUN CGO_ENABLED=0 GOOS=linux go build -a -installsuffix cgo -o app .

FROM alpine:latest  
RUN apk --no-cache add ca-certificates
WORKDIR /root/
COPY --from=builder /go/src/github.com/alexellis/href-counter/app    .
CMD ["./app"]  

The result would be two images, one for building, one with just the resulting app (much, much smaller)

REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

what is a base image?

A set of files, plus EXPOSE'd ports, ENTRYPOINT and CMD.
You can add files and build a new image based on that base image, with a new Dockerfile starting with a FROM directive: the image mentioned after FROM is "the base image" for your new image.

does it mean that if I declare neo4j/neo4j in a FROM directive, that when my image is run the neo database will automatically run and be available within the container on port 7474?

Only if you don't overwrite CMD and ENTRYPOINT.
But the image in itself is enough: you would use a FROM neo4j/neo4j if you had to add files related to neo4j for your particular usage of neo4j.

And using the joiner from http://jinja.pocoo.org/docs/dev/templates/#joiner

{% set comma = joiner(",") %}
{% for user in userlist %}
    {{ comma() }}<a href="/profile/{{ user }}/">{{ user }}</a>
{% endfor %}  

It's made for this exact purpose. Normally a join or a check of forloop.last would suffice for a single list, but for multiple groups of things it's useful.

A more complex example on why you would use it.

{% set pipe = joiner("|") %}
{% if categories %} {{ pipe() }}
    Categories: {{ categories|join(", ") }}
{% endif %}
{% if author %} {{ pipe() }}
    Author: {{ author() }}
{% endif %}
{% if can_edit %} {{ pipe() }}
    <a href="?action=edit">Edit</a>
{% endif %}

1) Install GhostScript

2) Install ImageMagick

3) Create "Convert-to-TIFF.bat" (Windows XP, Vista, 7) and use the following line:

for %%f in (%*) DO "C:\Program Files\ImageMagick-6.6.4-Q16\convert.exe" -density 300 -compress lzw %%f %%f.tiff

Dragging any number of single-page PDF files onto this file will convert them to compressed TIFFs, at 300 DPI.

I have been hunting around trying to solve this one for a while and none of the suggested updates to bash seemed to be working. What I discovered was that some point my npm root was modified such that it was pointing to a Users/USER_NAME/.node/node_modules while the actual installation of npm was living at /usr/local/lib/node_modules. You can check this by running npm root and npm root -g (for the global installation). To correct the path you can call npm config set prefix /usr/local.

Have you tried to remove the proxy username and password? A similar poster encountered that issue:

Could not calculate build plan: Plugin org.apache.maven.plugins:maven-jar-plugin:2.3.2 or one of its dependencies could not be resolved

Failing that I found the following worked:

1. Delete project in Eclipse (but do not delete the contents on disk)
2. Delete all files in your Maven repository
3. Re-download all Maven dependencies:

mvn dependency:resolve

4. Start up Eclipse
5. Ensure that Eclipse is configured to use your external Maven installation (Window->Preferences->Maven->Installations)
6. Re-import the existing project(s) into Eclipse
7. Ensure that there are no Maven Eclipse plugin errors on the final screen of the project import

In first statement you define variable, which common for all of the objects (class static field).

In the second statement you define variable, which belongs to each created object (a lot of copies).

In your case you should use the first one.

This answer is based on an article that no longer exists:

Summary of article:

"Basically, WCF is a service layer that allows you to build applications that can communicate using a variety of communication mechanisms. With it, you can communicate using Peer to Peer, Named Pipes, Web Services and so on.

You can’t compare them because WCF is a framework for building interoperable applications. If you like, you can think of it as a SOA enabler. What does this mean?

Well, WCF conforms to something known as ABC, where A is the address of the service that you want to communicate with, B stands for the binding and C stands for the contract. This is important because it is possible to change the binding without necessarily changing the code. The contract is much more powerful because it forces the separation of the contract from the implementation. This means that the contract is defined in an interface, and there is a concrete implementation which is bound to by the consumer using the same idea of the contract. The datamodel is abstracted out."

... later ...

"should use WCF when we need to communicate with other communication technologies (e,.g. Peer to Peer, Named Pipes) rather than Web Service"

Alternatively you can use:

this.element=$(id)[0];

Any time you do a remove() or a removeAll(), you should call

  validate();
  repaint();

after you have completed add()'ing the new components.

Calling validate() or revalidate() is mandatory when you do a remove() - see the relevant javadocs.

My own testing indicates that repaint() is also necessary. I'm not sure exactly why.

You can also set a Java property, i.e. environment variable, on the command line and easily use it anywhere in your code.

The command line would be done this way:

c:/> java -jar -Dmyvar=enwiki-20111007-pages-articles.xml wiki2txt

and the java code accesses the value like this:

String context = System.getProperty("myvar"); 

See this question about argument passing in Java.

Just move the extra condition into the JOIN ON criteria, this way the existence of b is not required to return a result

SELECT a.* FROM a 
    LEFT JOIN b ON a.group_id=b.group_id AND b.user_id!=$_SESSION{['user_id']} 
    WHERE a.keyword LIKE '%".$keyword."%' 
    GROUP BY group_id

I've found the liquibase.database.typeconversion.core.AbstractTypeConverter class. It lists all types that can be used:

protected DataType getDataType(String columnTypeString, Boolean autoIncrement, String dataTypeName, String precision, String additionalInformation) {
    // Translate type to database-specific type, if possible
    DataType returnTypeName = null;
    if (dataTypeName.equalsIgnoreCase("BIGINT")) {
        returnTypeName = getBigIntType();
    } else if (dataTypeName.equalsIgnoreCase("NUMBER") || dataTypeName.equalsIgnoreCase("NUMERIC")) {
        returnTypeName = getNumberType();
    } else if (dataTypeName.equalsIgnoreCase("BLOB")) {
        returnTypeName = getBlobType();

It seems to me you have not called srand first. Usage example here.

Quickselect works in O(n), this is also used in the partition step of Quicksort.

Output one image every minute, named img001.jpg, img002.jpg, img003.jpg, etc. The %03d dictates that the ordinal number of each output image will be formatted using 3 digits.

ffmpeg -i myvideo.avi -vf fps=1/60 img%03d.jpg

Change the fps=1/60 to fps=1/30 to capture a image every 30 seconds. Similarly if you want to capture a image every 5 seconds then change fps=1/60 to fps=1/5

If you request resources, then RESTful API is better by design. If you request some complicated data with a lot of parameters and complicated methods other than simple CRUD, then RPC is the right way to go.

I would say, it depends on the default. For example

public Bar
{
  ArrayList<Foo> foos;
}

I would make a new ArrayList outside of the constructor, if I always assume foos can not be null. If Bar is a valid object, not caring if foos is null or not, I would put it in the constructor.

You might disagree and say that it's the constructors job to put the object in a valid state. However, if clearly all the constructors should do exactly the same thing(initialize foos), why duplicate that code?

Correction for What does it mean to bind a multicast (udp) socket? as long as it partially true at the following quote:

The "bind" operation is basically saying, "use this local UDP port for sending and receiving data. In other words, it allocates that UDP port for exclusive use for your application

There is one exception. Multiple applications can share the same port for listening (usually it has practical value for multicast datagrams), if the SO_REUSEADDR option applied. For example

int sock = socket(AF_INET, SOCK_DGRAM, IPPROTO_UDP); // create UDP socket somehow
...
int set_option_on = 1;
// it is important to do "reuse address" before bind, not after
int res = setsockopt(sock, SOL_SOCKET, SO_REUSEADDR, (char*) &set_option_on, 
    sizeof(set_option_on));
res = bind(sock, src_addr, len);

If several processes did such "reuse binding", then every UDP datagram received on that shared port will be delivered to each of the processes (providing natural joint with multicasts traffic).

Here are further details regarding what happens in a few cases:

1. attempt of any bind ("exclusive" or "reuse") to free port will be successful

2. attempt to "exclusive binding" will fail if the port is already "reuse-binded"

3. attempt to "reuse binding" will fail if some process keeps "exclusive binding"

I simply use in every test a method tearDown() as following and I have no problem at all.

@AfterTest
public void tearDown() {
    driver.quit();
    driver = null;
}

After quitting the driver instance clear it from the cache by driver = null

Hope the answer the question

If you don't mind the set to be sorted then you may be interested to take a look at the indexed-tree-map project.

The enhanced TreeSet/TreeMap provides access to elements by index or getting the index of an element. And the implementation is based on updating node weights in the RB tree. So no iteration or backing up by a list here.

Within your template, you can use Django's date filter. E.g.:

<p>Birthday: {{ birthday|date:"M d, Y" }}</p>

Gives:

Birthday: Jan 29, 1983

More formatting examples in the date filter docs.

I used this method to change choosing Text Field

- (BOOL)textFieldShouldReturn:(UITextField *)textField {

if ([textField isEqual:self.emailRegisterTextField]) {

    [self.usernameRegisterTextField becomeFirstResponder];

} else if ([textField isEqual:self.usernameRegisterTextField]) {

    [self.passwordRegisterTextField becomeFirstResponder];

} else {

    [textField resignFirstResponder];

    // To click button for registration when you clicking button "Done" on the keyboard
    [self createMyAccount:self.registrationButton];
}

return YES;

}

No my friend its very simple, try using this:

AlertDialog alertDialog = new AlertDialog.Builder(AlertDialogActivity.this).create();
alertDialog.setTitle("Alert Dialog");
alertDialog.setMessage("Welcome to dear user.");
alertDialog.setIcon(R.drawable.welcome);

alertDialog.setButton(AlertDialog.BUTTON_POSITIVE, "OK", new DialogInterface.OnClickListener() {
    public void onClick(DialogInterface dialog, int which) {
        Toast.makeText(getApplicationContext(), "You clicked on OK", Toast.LENGTH_SHORT).show();
    }
});

alertDialog.show();

This tutorial shows how you can create custom dialog using xml and then show them as an alert dialog.

#! /bin/sh
echo "$(cd "$(dirname "$1")"; pwd -P)/$(basename "$1")"

I am also new to R but trying to understand how ggplot works I think I get another way to do it. I just share probably not as a complete perfect solution but to add some different points of view.

I know ggplot is made to work with dataframes better but maybe it can be also sometimes useful to know that you can directly plot two vectors without using a dataframe.

Loading data. Original date vector length is 100 while var0 and var1 have length 50 so I only plot the available data (first 50 dates).

var0 <- 100 + c(0, cumsum(runif(49, -20, 20)))
var1 <- 150 + c(0, cumsum(runif(49, -10, 10)))
date <- seq(as.Date("2002-01-01"), by="1 month", length.out=50)    

Plotting

ggplot() + geom_line(aes(x=date,y=var0),color='red') + 
           geom_line(aes(x=date,y=var1),color='blue') + 
           ylab('Values')+xlab('date')

However I was not able to add a correct legend using this format. Does anyone know how?

The original code works fine for reading and separating the csv file data but you need to change the data type from csv to text.

if you are using the Material design library. Currently, I am using the version

implementation 'com.google.android.material:material:1.3.0-alpha01'

1 - Set color when TextInputLayout is resting.

<item name="android:textColorHint">@color/your_color_hint</item>

2 - Set color when TextInputLayout is floating/focused/tapped.

<item name="hintTextColor">@color/your_color_floating_hint</item>

3 - Set color of the line under TextInputLayout.

<item name="boxStrokeColor">@color/TextViewColor_line</item>

4 - Set color of the error under TextInputLayout.

<item name="boxStrokeErrorColor">@color/colorPrimary</item>

I have just rewritten the code to the following:

    $dbhost = "localhost";
    $dbname = "pdo";
    $dbusername = "root";
    $dbpassword = "845625";

    $link = new PDO("mysql:host=$dbhost;dbname=$dbname", $dbusername, $dbpassword);
    $link->setAttribute(PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION);

    $statement = $link->prepare("INSERT INTO testtable(name, lastname, age)
        VALUES(?,?,?)");

    $statement->execute(array("Bob","Desaunois",18));

And it seems to work now. BUT. if I on purpose cause an error to occur, it does not say there is any. The code works, but still; should I encounter more errors, I will not know why.

You can now do it like this

<cdk-cell [style.flex]="'0 0 75px'">

You haven't specified what language you are using but assuming C# / .NET you could use SOAP extensions.

Otherwise, use a sniffer such as Wireshark

1. Arange your word list with delimiter which never occures in the words, f.e. |
2. swap arguments in find call - we want search if cell value is matching one of the words in pattern string {=FIND("cell I want to search","list of words I want to search for")}
3. if the patterns are similar, there is a risk of getting more results than wanted, we restrict just correct results via adding &"|" to the cell value tested (works well with array formulas) cell G3 could contain: {=SUM(FIND($A$1:$A$100&"|";A3))} this ensures spreadsheet will compare strings like "cellvlaue|" againts "pattern1|", "pattern2|" etc. which sorts out conflicts like pattern1="newly added", pattern2="added" (sum of all cells matching "added" would be too high, including the target values for cells matching "newly added", which would be a logical error)

A call to Class#getResourceAsStream(String) delegates to the class loader and the resource is searched in the class path. In other words, you current code won't work and you should put abc.txt in WEB-INF/classes, or in WEB-INF/lib if packaged in a jar file.

Or use ServletContext.getResourceAsStream(String) which allows servlet containers to make a resource available to a servlet from any location, without using a class loader. So use this from a Servlet:

this.getServletContext().getResourceAsStream("/WEB-INF/abc.txt") ;

But is there a way I can call getServletContext from my Web Service?

If you are using JAX-WS, then you can get a WebServiceContext injected:

@Resource
private WebServiceContext wsContext;

And then get the ServletContext from it:

ServletContext sContext= wsContext.getMessageContext()
                             .get(MessageContext.SERVLET_CONTEXT));

Edit your phpmyadmin config.inc.php file and if you have Password, insert that in front of Password in following code:

$cfg['Servers'][$i]['verbose'] = 'localhost';
$cfg['Servers'][$i]['host'] = 'localhost';
$cfg['Servers'][$i]['port'] = '3306';
$cfg['Servers'][$i]['socket'] = '';
$cfg['Servers'][$i]['connect_type'] = 'tcp';
$cfg['Servers'][$i]['extension'] = 'mysqli';
$cfg['Servers'][$i]['auth_type'] = 'config';
$cfg['Servers'][$i]['user'] = '**your-root-username**';
$cfg['Servers'][$i]['password'] = '**root-password**';
$cfg['Servers'][$i]['AllowNoPassword'] = true;

One method is:

tar -cf my_archive.tar $( find -name "*.php" -or -name "*.html" )

There are some caveats with this method however:

1. It will fail if there are any files or directories with spaces in them, and
2. it will fail if there are so many files that the maximum command line length is full.

A workaround to these could be to output the contents of the find command into a file, and then use the "-T, --files-from FILE" option to tar.

What i do ;

<body>
<script>
function getWidth(){
return Math.max(document.body.scrollWidth,
document.documentElement.scrollWidth,
document.body.offsetWidth,
document.documentElement.offsetWidth,
document.documentElement.clientWidth);
}
var aWidth=getWidth();
</script>
...

and call aWidth variable anywhere afterwards.

You need to put the getWidth() up in your document body to make sure that the scrollbar width is counted, else scrollbar width of the browser subtracted from getWidth().

You will have to change some of your data types but the basics of what you just posted could be converted to something similar to this given the data types I used may not be accurate.

Dim DateToday As String: DateToday = Format(Date, "yyyy/MM/dd")
Dim Computers As New Collection
Dim disabledList As New Collection
Dim compArray(1 To 1) As String

'Assign data to first item in array
compArray(1) = "asdf"

'Format = Item, Key
Computers.Add "ErrorState", "Computer Name"

'Prints "ErrorState"
Debug.Print Computers("Computer Name")

Collections cannot be sorted so if you need to sort data you will probably want to use an array.

Here is a link to the outlook developer reference. http://msdn.microsoft.com/en-us/library/office/ff866465%28v=office.14%29.aspx

Another great site to help you get started is http://www.cpearson.com/Excel/Topic.aspx

Moving everything over to VBA from VB.Net is not going to be simple since not all the data types are the same and you do not have the .Net framework. If you get stuck just post the code you're stuck converting and you will surely get some help!

Edit:

Sub ArrayExample()
    Dim subject As String
    Dim TestArray() As String
    Dim counter As Long

    subject = "Example"
    counter = Len(subject)

    ReDim TestArray(1 To counter) As String

    For counter = 1 To Len(subject)
        TestArray(counter) = Right(Left(subject, counter), 1)
    Next
End Sub

This issue boiled down to how I was building my select2 select box. In one javascript file I had...

$(function(){
  $(".select2").select2();
});

And in another js file an override...

$(function(){
    var employerStateSelector = 
                $("#registration_employer_state").select2("destroy");
    employerStateSelector.select2({
    placeholder: 'Select a State...'
    });
});

Moving the second override into a window load event resolved the issue.

$( window ).load(function() {
  var employerStateSelector = 
              $("#registration_employer_state").select2("destroy");
  employerStateSelector.select2({
    placeholder: 'Select a State...'
  });
});

This issue blossomed inside a Rails application

In my case above mentioned methods work fine with php but when i try to upload files with these methods in node.js then i have some problem. So instead of using $http({..,..,...}) use the normal jquery ajax.

For select file use this

<input type="file" name="file" onchange="angular.element(this).scope().uploadFile(this)"/>

And in controller

$scope.uploadFile = function(element) {   
var data = new FormData();
data.append('file', $(element)[0].files[0]);
jQuery.ajax({
      url: 'brand/upload',
      type:'post',
      data: data,
      contentType: false,
      processData: false,
      success: function(response) {
      console.log(response);
      },
      error: function(jqXHR, textStatus, errorMessage) {
      alert('Error uploading: ' + errorMessage);
      }
 });   
};

Try this :

SELECT
    (
      SELECT
          `NAME`
      FROM
          locations
      WHERE
          ID = school_locations.LOCATION_ID
    ) as `NAME`
FROM
     school_locations
WHERE
     (
      SELECT
          `TYPE`
      FROM
          locations
      WHERE
          ID = school_locations.LOCATION_ID
     ) = 'coun';

You can add Row in a single line

    DataTable table = new DataTable();
    table.Columns.Add("Dosage", typeof(int));
    table.Columns.Add("Drug", typeof(string));
    table.Columns.Add("Patient", typeof(string));
    table.Columns.Add("Date", typeof(DateTime));

    // Here we add five DataRows.
    table.Rows.Add(25, "Indocin", "David", DateTime.Now);
    table.Rows.Add(50, "Enebrel", "Sam", DateTime.Now);
    table.Rows.Add(10, "Hydralazine", "Christoff", DateTime.Now);
    table.Rows.Add(21, "Combivent", "Janet", DateTime.Now);
    table.Rows.Add(100, "Dilantin", "Melanie", DateTime.Now);

I think the toast maybe a good method to show the value of a variable!

You can also format the string like so:

>>> print ("{index}. {word} appears {count} times".format(index=1, word='Hello', count=42))

Which outputs

1. Hello appears 42 times.

Because the values are named, their order does not matter. Making the example below output the same as the above example.

>>> print ("{index}. {word} appears {count} times".format(count=42, index=1, word='Hello'))

Formatting string this way allows you to do this.

>>> data = {'count':42, 'index':1, 'word':'Hello'}
>>> print ("{index}. {word} appears {count} times.".format(**data))
1. Hello appears 42 times.

Your approach is good but the problem is that you use "*" instead enlisting fields names. If you put all the columns names excep primary key your script will work like charm on one or many records.

INSERT INTO invoices (iv.field_name, iv.field_name,iv.field_name
) SELECT iv.field_name, iv.field_name,iv.field_name FROM invoices AS iv     
WHERE iv.ID=XXXXX

You could do it with jQuery.

$('.myClass').click(function() {
  alert('hohoho');
});

Bit counter-intuitive, but you must first setup a SDK for Java projects. On the bottom right of the IntelliJ welcome screen, select 'Configure > Project Defaults > Project Structure'.

The Project tab on the left will show that you have no SDK selected:

Therefore, you must click the 'New...' button on the right hand side of the dropdown and point it to your JDK. After that, you can go back to the import screen and it should be populated with your JAVA_HOME variable, providing you have this set.

Mine showed up in VS2010 after writing the first parenthesis..

so, prams.Add(

After doings something like that, the box with the up and down arrows appeared.

Just cast the int to the enumeration type:

EnumDisplayStatus status = (EnumDisplayStatus) statusFromDatabase;
string statusString = status.ToString();

Although an old question, the Location-bar project is very useful.

var LocationBar = require("location-bar");
var locationBar = new LocationBar();

// listen to all changes to the location bar
locationBar.onChange(function (path) {
  console.log("the current url is", path);
});

// listen to a specific change to location bar
// e.g. Backbone builds on top of this method to implement
// it's simple parametrized Backbone.Router
locationBar.route(/some\-regex/, function () {
  // only called when the current url matches the regex
});

locationBar.start({
  pushState: true
});

// update the address bar and add a new entry in browsers history
locationBar.update("/some/url?param=123");

// update the address bar but don't add the entry in history
locationBar.update("/some/url", {replace: true});

// update the address bar and call the `change` callback
locationBar.update("/some/url", {trigger: true});

For accessing the height of the status bar for Android devices, we prefer a programmatic way to get it:

Sample code

int resId = getResources().getIdentifier("status_bar_height", "dimen", "android");
if (resId > 0) {
    result = getResources().getDimensionPixelSize(resId);
}

The variable result gives the height in the pixel.

For quick access

For more information about height of Title bar, Navigation bar and Content View, kindly look on Android Device Screen Sizes.

Here's another way to plot the data, involves turning the date_time into an index, this might help you for future slicing

#convert column to datetime
trip_data['lpep_pickup_datetime'] = pd.to_datetime(trip_data['lpep_pickup_datetime'])
#turn the datetime to an index
trip_data.index = trip_data['lpep_pickup_datetime']
#Plot
trip_data['Trip_distance'].plot(kind='hist')
plt.show()

There are some simple ways, like:

File file = new File("filename.txt");
PrintWriter pw = new PrintWriter(file);

pw.write("The world I'm coming");
pw.close();

String write = "Hello World!";

FileWriter fw = new FileWriter(file);
BufferedWriter bw = new BufferedWriter(fw);

fw.write(write);

fw.close();

Via: http://blog.isotoma.com/2012/03/html5-input-typenumber-and-decimalsfloats-in-chrome/

But what if you want all the numbers to be valid, integers and decimals alike? In this case, set step to “any”

<input type="number" step="any" />

Works for me in Chrome, not tested in other browsers.

This function will tell you the x,y position of the element relative to the page. Basically you have to loop up through all the element's parents and add their offsets together.

function getPos(el) {
    // yay readability
    for (var lx=0, ly=0;
         el != null;
         lx += el.offsetLeft, ly += el.offsetTop, el = el.offsetParent);
    return {x: lx,y: ly};
}

However, if you just wanted the x,y position of the element relative to its container, then all you need is:

var x = el.offsetLeft, y = el.offsetTop;

To put an element directly below this one, you'll also need to know its height. This is stored in the offsetHeight/offsetWidth property.

var yPositionOfNewElement = el.offsetTop + el.offsetHeight + someMargin;
