Run: python -c "import ssl; print(ssl.get_default_verify_paths())" to check the current paths which are used to verify the certificate. Add your company's root certificate to one of those.

The path openssl_capath_env points to the environment variable: SSL_CERT_DIR.

If SSL_CERT_DIR doesn't exist, you will need to create it and point it to a valid folder within your filesystem. You can then add your certificate to this folder to use it.

Here the code to use your app.js

input specifies file name

res.download(__dirname+'/'+input);

I recommend you to look at new p2p live protocol Bittorent Live.

As for streaming it's better to use UDP, first because it lowers the load on servers, but mostly because you can send packets with multicast, it's simpler than sending it to each connected client.

VMDK/VMX are VMWare file formats but you can use it with VirtualBox:

1. Create a new Virtual Machine and when asks for a hard disk choose "Use an existing hard disk"
2. Click on the "button with folder and green arrow image on the combo box right" which opens Virtual Media Manager, it looks like this (you can open it directly pressing CTRL+D on main window or in File > Virtual Media Manager menu)...
3. Then you can add the VMDK/VMX hard disk image and setup it for your virtual machine :)

While you can't directly recover a MySQL password without bruteforcing, there might be another way - if you've used MySQL Workbench to connect to the database, and have saved the credentials to the "vault", you're golden.

On Windows, the credentials are stored in %APPDATA%\MySQL\Workbench\workbench_user_data.dat - encrypted with CryptProtectData (without any additional entropy). Decrypting is easy peasy:

std::vector<unsigned char> decrypt(BYTE *input, size_t length) {
    DATA_BLOB inblob { length, input };
    DATA_BLOB outblob;

    if (!CryptUnprotectData(&inblob, NULL, NULL, NULL, NULL, CRYPTPROTECT_UI_FORBIDDEN, &outblob)) {
            throw std::runtime_error("Couldn't decrypt");
    }

    std::vector<unsigned char> output(length);
    memcpy(&output[0], outblob.pbData, outblob.cbData);

    return output;
}

Or you can check out this DonationCoder thread for source + executable of a quick-and-dirty implementation.

I just restarted Visual Studio and did IISRESET which solved the problem.

That DateTime format is actually ISO 8601 DateTime. JSON does not specify any particular format for dates/times. If you Google a bit, you will find plenty of implementations to parse it in Java.

Here's one

If you are open to using something other than Java's built-in Date/Time/Calendar classes, I would also suggest Joda Time. They offer (among many things) a ISODateTimeFormat to parse these kinds of strings.

Django-model-values (disclosure: author) provides an implementation of the NotEqual lookup, as in this answer. It also provides syntactic support for it:

from model_values import F
Model.objects.exclude(F.x != 5, a=True)

Public: is a default state when you declare a variable or method, can be accessed by anything directly to the object.

Protected: Can be accessed only within the object and subclasses.

Private: Can be referenced only within the object, not subclasses.

If you run your code from an installed package, make sure template files are present in directory <python root>/lib/site-packages/your-package/templates.

Some details:

In my case I was trying to run examples of project flask_simple_ui and jinja would always say

jinja2.exceptions.TemplateNotFound: form.html

The trick was that sample program would import installed package flask_simple_ui. And ninja being used from inside that package is using as root directory for lookup the package path, in my case ...python/lib/site-packages/flask_simple_ui, instead of os.getcwd() as one would expect.

To my bad luck, setup.py has a bug and doesn't copy any html files, including the missing form.html. Once I fixed setup.py, the problem with TemplateNotFound vanished.

I hope it helps someone.

    public delegate void MessageProcessor<T>(T msg) where T : IExternalizable;


    virtual public void OnRecivedMessage(IExternalizable msg)
    {
        Type type = msg.GetType();
        ArrayList list = processors.Get(type);

        {
            object[] args = new object[]{msg};

for me , in sql server 2016, I do it like this

*To rename column Column1 to column2

EXEC sp_rename 'dbo.T_Table1.Column1', 'Column2', 'COLUMN'

*To modify column Type from string to int:( Please be sure that data are in the correct format)

ALTER TABLE dbo.T_Table1 ALTER COLUMN Column2  int; 

You can run a script, or a more complex parameter to the RUN. Here is an example from a Dockerfile I've downloaded to look at previously:

RUN cd /opt && unzip treeio.zip && mv treeio-master treeio && \
    rm -f treeio.zip && cd treeio && pip install -r requirements.pip

Because of the use of '&&', it will only get to the final 'pip install' command if all the previous commands have succeeded.

In fact, since every RUN creates a new commit & (currently) an AUFS layer, if you have too many commands in the Dockerfile, you will use up the limits, so merging the RUNs (when the file is stable) can be a very useful thing to do.

try this

  Calendar c = Calendar.getInstance(); 
  int mseconds = c.get(Calendar.MILLISECOND)

an alternative would be

 Calendar rightNow = Calendar.getInstance();

 long offset = rightNow.get(Calendar.ZONE_OFFSET) +
        rightNow.get(Calendar.DST_OFFSET);
 long sinceMid = (rightNow.getTimeInMils() + offset) %
       (24 * 60 * 60 * 1000);

  System.out.println(sinceMid + " milliseconds since midnight");

If you want to access folder you specified using Anaconda Prompt, try typing

cd C:\Users\u354590

Want to center an image? Very easy, Bootstrap comes with two classes, .center-block and text-center.

Use the former in the case of your image being a BLOCK element, for example, adding img-responsive class to your img makes the img a block element. You should know this if you know how to navigate in the web console and see applied styles to an element.

Don't want to use a class? No problem, here is the CSS bootstrap uses. You can make a custom class or write a CSS rule for the element to match the Bootstrap class.

 // In case you're dealing with a block element apply this to the element itself 
.center-block {
   margin-left:auto;
   margin-right:auto;
   display:block;
}

// In case you're dealing with a inline element apply this to the parent 
.text-center {
   text-align:center
}

I use lots of erasing level

String donen = "lots of stupid whitespaces and new lines and others..."

//Remove multilines
donen = Regex.Replace(donen, @"^\s+$[\r\n]*", "", RegexOptions.Multiline);
//remove multi whitespaces
RegexOptions options = RegexOptions.None;
Regex regex = new Regex("[ ]{2,}", options);
donen = regex.Replace(donen, " ");
//remove tabs
char tab = '\u0009';
donen = donen.Replace(tab.ToString(), "");
//remove endoffile newlines
donen = donen.TrimEnd('\r', '\n');
//to be sure erase new lines again from another perspective
donen.Replace(Environment.NewLine, "");

and now we have a clean one row

R has multiple ways of represeting time series. Since you're working with daily prices of stocks, you may wish to consider that financial markets are closed on weekends and business holidays so that trading days and calendar days are not the same. However, you may need to work with your times series in terms of both trading days and calendar days. For example, daily returns are calculated from sequential daily closing prices regardless of whether a weekend intervenes. But you may also want to do calendar-based reporting such as weekly price summaries. For these reasons the xts package, an extension of zoo, is commonly used with financial data in R. An example of how it could be used with your data follows.

Assuming the data shown in your example is in the dataframe df

  library(xts)
  stocks <- xts(df[,-1], order.by=as.Date(df[,1], "%m/%d/%Y"))
#
#  daily returns
#
   returns <- diff(stocks, arithmetic=FALSE ) - 1
#
#  weekly open, high, low, close reports
#
   to.weekly(stocks$Hero_close, name="Hero")

which gives the output

           Hero.Open Hero.High Hero.Low Hero.Close
2013-03-15    1669.1   1684.45   1669.1    1684.45
2013-03-22    1690.5   1690.50   1623.3    1659.60
2013-03-28    1617.7   1617.70   1542.0    1542.00

If you are just going to verify/validate the entered user name and password, use the Rfc2898DerivedBytes class (also known as Password Based Key Derivation Function 2 or PBKDF2). This is more secure than using encryption like Triple DES or AES because there is no practical way to go from the result of RFC2898DerivedBytes back to the password. You can only go from a password to the result. See Is it ok to use SHA1 hash of password as a salt when deriving encryption key and IV from password string? for an example and discussion for .Net or String encrypt / decrypt with password c# Metro Style for WinRT/Metro.

If you are storing the password for reuse, such as supplying it to a third party, use the Windows Data Protection API (DPAPI). This uses operating system generated and protected keys and the Triple DES encryption algorithm to encrypt and decrypt information. This means your application does not have to worry about generating and protecting the encryption keys, a major concern when using cryptography.

In C#, use the System.Security.Cryptography.ProtectedData class. For example, to encrypt a piece of data, use ProtectedData.Protect():

// Data to protect. Convert a string to a byte[] using Encoding.UTF8.GetBytes().
byte[] plaintext; 

// Generate additional entropy (will be used as the Initialization vector)
byte[] entropy = new byte[20];
using(RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider())
{
    rng.GetBytes(entropy);
}

byte[] ciphertext = ProtectedData.Protect(plaintext, entropy,
    DataProtectionScope.CurrentUser);

Store the entropy and ciphertext securely, such as in a file or registry key with permissions set so only the current user can read it. To get access to the original data, use ProtectedData.Unprotect():

byte[] plaintext= ProtectedData.Unprotect(ciphertext, entropy,
    DataProtectionScope.CurrentUser);

Note that there are additional security considerations. For example, avoid storing secrets like passwords as a string. Strings are immutable, being they cannot be notified in memory so someone looking at the application's memory or a memory dump may see the password. Use SecureString or a byte[] instead and remember to dispose or zero them as soon as the password is no longer needed.

Is m_cRedundencyManager able to use member functions? Most callbacks are set up to use regular functions or static member functions. Take a look at this page at C++ FAQ Lite for more information.

Update: The function declaration you provided shows that m_cRedundencyManager is expecting a function of the form: void yourCallbackFunction(int, void *). Member functions are therefore unacceptable as callbacks in this case. A static member function may work, but if that is unacceptable in your case, the following code would also work. Note that it uses an evil cast from void *.

// in your CLoggersInfra constructor:
m_cRedundencyManager->Init(myRedundencyManagerCallBackHandler, this);

// in your CLoggersInfra header:
void myRedundencyManagerCallBackHandler(int i, void * CLoggersInfraPtr);

// in your CLoggersInfra source file:
void myRedundencyManagerCallBackHandler(int i, void * CLoggersInfraPtr)
{
    ((CLoggersInfra *)CLoggersInfraPtr)->RedundencyManagerCallBack(i);
}

Use subshell:

echo "$(echo -n 'hello'; cat filename)" > filename

Unfortunately, command substitution will remove newlines at the end of file. So as to keep them one can use:

echo -n "hello" | cat - filename > /tmp/filename.tmp
mv /tmp/filename.tmp filename

Neither grouping nor command substitution is needed.

open the location in terminal then type these commands 1. chmod +x filename.sh 2. ./filename.sh that's it

There's a better solution if you don't really need the memory address but rather some means of uniquely identifying a managed object:

using System.Runtime.CompilerServices;

public static class Extensions
{
    private static readonly ConditionalWeakTable<object, RefId> _ids = new ConditionalWeakTable<object, RefId>();

    public static Guid GetRefId<T>(this T obj) where T: class
    {
        if (obj == null)
            return default(Guid);

        return _ids.GetOrCreateValue(obj).Id;
    }

    private class RefId
    {
        public Guid Id { get; } = Guid.NewGuid();
    }
}

This is thread safe and uses weak references internally, so you won't have memory leaks.

You can use any key generation means that you like. I'm using Guid.NewGuid() here because it's simple and thread safe.

Update

I went ahead and created a Nuget package Overby.Extensions.Attachments that contains some extension methods for attaching objects to other objects. There's an extension called GetReferenceId() that effectively does what the code in this answer shows.

They're completely different things.

A join allows you to relate similar data in different tables.

A union returns the results of two different queries as a single recordset.

Use the matplotlib savefig function with the keyword argument transparent=True to save the image as a png file.

In [30]: x = np.linspace(0,6,31)

In [31]: y = np.exp(-0.5*x) * np.sin(x)

In [32]: plot(x, y, 'bo-')
Out[32]: [<matplotlib.lines.Line2D at 0x3f29750>]            

In [33]: savefig('demo.png', transparent=True)

Result:

Of course, that plot doesn't demonstrate the transparency. Here's a screenshot of the PNG file displayed using the ImageMagick display command. The checkerboard pattern is the background that is visible through the transparent parts of the PNG file.

under etc/apache2/apache2.conf, you can find one or more blocks that describe the server directories and permissions

As an example, this is the default configuration

<Directory /var/www/>
   Options Indexes FollowSymLinks
   AllowOverride None
   Require all granted
</Directory>

you can replicate this but change the directory path /var/www/ with the new directory.

Finally, you need to restart the apache server, you can do that from a terminal with the command: sudo service apache2 restart

Twitter Bootstrap provides classes for toggling content, see https://github.com/twbs/bootstrap/blob/3ee5542c990817324f0a07b97d01d1fe206fd8d6/less/utilities.less.

I'm completely new to jQuery, and after reading their docs I came to another solution to combine Twitter Bootstrap + jQuery.

First, the solution to 'hide' and 'show' an element (class wsis-collapse) when clicking on another element (class wsis-toggle), is to use .toggle.

jQuery(document).ready(function() {
    jQuery(".wsis-toggle").click(function(){
        jQuery(".wsis-collapse").toggle();
    });
});

You already have hidden the element .wsis-collapse by using Twitter Bootstrap (V3) class .hidden also:

.hidden {
  display: none !important;
  visibility: hidden !important;
}

When you click on .wsis-toggle, the jQuery is adding an inline style:

display: block

Because of the !important in the Twitter Bootstrap, this inline style has no effect, so we need to remove the .hidden class, but I won't recommend .removeClass for this! Because when jQuery is going to hide something again, it's also adding an inline style:

display: none

This is not the same as the .hidden class of Twitter Bootstrap, which is optimized for AT as well (screen readers). So, if we want to show the hidden div, we need to get rid of the .hidden class of Twitter Bootstrap, so we get rid of the important statements, but if we hide it again, we want to have the .hidden class back again! We can using [.toggleClass][3] for this.

jQuery(document).ready(function() {
    jQuery(".wsis-toggle").click(function(){
        jQuery(".wsis-collapse").toggle().toggleClass( "hidden" );
    });
});

This way you keep using the hidden class every time the content is hidden.

The .show class in TB is actually the same as the inline style of the jQuery, both 'display: block'. But if the .show class at some point will be different, then you simply add this class as well:

jQuery(document).ready(function() {
    jQuery(".wsis-toggle").click(function(){
        jQuery(".wsis-collapse").toggle().toggleClass( "hidden show" );
    });
});

I used placeholders so just follow along, as you might want to still keep the inheritance from the original style.

Before

<android.support.v7.widget.Toolbar
    android:id="@+id/toolBar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    android:elevation="4dp"
    android:theme="@style/{{originalBaseStyle}}"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

After:

styles.xml

<style name="{{yourToolbarStyle}}" parent="{{originalBaseStyle}}">
    <item name="android:textColorPrimary">@android:color/white</item>
    <item name="android:textColorSecondary">@android:color/white</item>
    <item name="actionMenuTextColor">@android:color/white</item>
    <item name="actionOverflowButtonStyle">@style/ActionButtonOverflowStyle</item>
    <item name="drawerArrowStyle">@style/DrawerArrowStyle</item>
</style>

Therefore

<android.support.v7.widget.Toolbar
    android:id="@+id/toolBar"
    android:layout_width="match_parent"
    android:layout_height="?attr/actionBarSize"
    android:background="?attr/colorPrimary"
    android:elevation="4dp"
    android:theme="@style/{{yourToolbarStyle}}"
    app:popupTheme="@style/ThemeOverlay.AppCompat.Light"/>

Here is the function which help you

private void saveBitmap(Bitmap bitmap,String path){
        if(bitmap!=null){
            try {
                FileOutputStream outputStream = null;
                try {
                    outputStream = new FileOutputStream(path); //here is set your file path where you want to save or also here you can set file object directly

                    bitmap.compress(Bitmap.CompressFormat.PNG, 100, outputStream); // bitmap is your Bitmap instance, if you want to compress it you can compress reduce percentage
                    // PNG is a lossless format, the compression factor (100) is ignored
                } catch (Exception e) {
                    e.printStackTrace();
                } finally {
                    try {
                        if (outputStream != null) {
                            outputStream.close();
                        }
                    } catch (IOException e) {
                        e.printStackTrace();
                    }
                }
            } catch (Exception e) {
                e.printStackTrace();
            }    
        }
    }

Use dispatch groups: see here for an example, "Waiting on Groups of Queued Tasks" in the "Dispatch Queues" chapter of Apple's iOS Developer Library's Concurrency Programming Guide

Your example could look something like this:

dispatch_group_t group = dispatch_group_create();

dispatch_group_async(group,dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^ {
    // block1
    NSLog(@"Block1");
    [NSThread sleepForTimeInterval:5.0];
    NSLog(@"Block1 End");
});


dispatch_group_async(group,dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^ {
    // block2
    NSLog(@"Block2");
    [NSThread sleepForTimeInterval:8.0];
    NSLog(@"Block2 End");
});

dispatch_group_notify(group,dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_HIGH, 0), ^ {
    // block3
    NSLog(@"Block3");
});

// only for non-ARC projects, handled automatically in ARC-enabled projects.
dispatch_release(group);

and could produce output like this:

2012-08-11 16:10:18.049 Dispatch[11858:1e03] Block1
2012-08-11 16:10:18.052 Dispatch[11858:1d03] Block2
2012-08-11 16:10:23.051 Dispatch[11858:1e03] Block1 End
2012-08-11 16:10:26.053 Dispatch[11858:1d03] Block2 End
2012-08-11 16:10:26.054 Dispatch[11858:1d03] Block3

Database Helper Class:

A helper class to manage database creation and version management.

You create a subclass implementing onCreate(SQLiteDatabase), onUpgrade(SQLiteDatabase, int, int) and optionally onOpen(SQLiteDatabase), and this class takes care of opening the database if it exists, creating it if it does not, and upgrading it as necessary. Transactions are used to make sure the database is always in a sensible state.

This class makes it easy for ContentProvider implementations to defer opening and upgrading the database until first use, to avoid blocking application startup with long-running database upgrades.

you could use display: inline-block;

hope it is useful.

"At run time, the authorization module iterates through the allow and deny elements, starting at the most local configuration file, until the authorization module finds the first access rule that fits a particular user account. Then, the authorization module grants or denies access to a URL resource depending on whether the first access rule found is an allow or a deny rule. The default authorization rule is . Thus, by default, access is allowed unless configured otherwise."

Article at MSDN

deny = * means deny everyone
deny = ? means deny unauthenticated users

In your 1st example deny * will not affect dan, matthew since they were already allowed by the preceding rule.

According to the docs, here is no difference in your 2 rule sets.

For a pure numpy implementation of Cartesian product of 1D arrays (or flat python lists), just use meshgrid(), roll the axes with transpose(), and reshape to the desired ouput:

 def cartprod(*arrays):
     N = len(arrays)
     return transpose(meshgrid(*arrays, indexing='ij'), 
                      roll(arange(N + 1), -1)).reshape(-1, N)

Note this has the convention of last axis changing fastest ("C style" or "row-major").

If you want to change the first axis fastest ("FORTRAN style" or "column-major"), just change the order parameter of reshape() like this: reshape((-1, N), order='F')

See any reference manual, such as the man page:

f,F

The double argument is rounded and converted to decimal notation in the style [-]ddd.ddd, where the number of digits after the decimal-point character is equal to the precision specification. If the precision is missing, it is taken as 6; if the precision is explicitly zero, no decimal-point character appears. If a decimal point appears, at least one digit appears before it. (The SUSv2 does not know about F and says that character string representations for infinity and NaN may be made available. The C99 standard specifies '[-]inf' or '[-]infinity' for infinity, and a string starting with 'nan' for NaN, in the case of f conversion, and '[-]INF' or '[-]INFINITY' or 'NAN*' in the case of F conversion.)

g,G

The double argument is converted in style f or e (or F or E for G conversions). The precision specifies the number of significant digits. If the precision is missing, 6 digits are given; if the precision is zero, it is treated as 1. Style e is used if the exponent from its conversion is less than -4 or greater than or equal to the precision. Trailing zeros are removed from the fractional part of the result; a decimal point appears only if it is followed by at least one digit.

In a Linux shell like bash/zsh:

DATABASE_TO_EMPTY="your_db_name";
{ echo "SET FOREIGN_KEY_CHECKS = 0;" ; \
  mysql "$DATABASE_TO_EMPTY" --skip-column-names -e \
  "SELECT concat('DROP TABLE IF EXISTS ', table_name, ';') \
   FROM information_schema.tables WHERE table_schema = '$DATABASE_TO_EMPTY';";\
  } | mysql "$DATABASE_TO_EMPTY"

This will generate the commands, then immediately pipe them to a 2nd client instance which will delete the tables.

The clever bit is of course copied from other answers here - I just wanted a copy-and-pasteable one-liner (ish) to actually do the job the OP wanted.

Note of course you'll have to put your credentials in (twice) in these mysql commands, too, unless you have a very low security setup. (or you could alias your mysql command to include your creds.)

This gives me the most reliable results:

Sub RangeToPicture()
  Dim FileName As String: FileName = "C:\file.bmp"
  Dim rPrt As Range: Set rPrt = ThisWorkbook.Sheets("Sheet1").Range("A1:C6")

  Dim chtObj As ChartObject
  rPrt.CopyPicture xlScreen, xlBitmap
  Set chtObj = ActiveSheet.ChartObjects.Add(1, 1, rPrt.Width, rPrt.Height)
  chtObj.Activate
  ActiveChart.Paste
  ActiveChart.Export FileName
  chtObj.Delete
End Sub

Writing dataframe to disk as csv is similar read from csv. If you want your result as one file, you can use coalesce.

df.coalesce(1)
      .write
      .option("header","true")
      .option("sep",",")
      .mode("overwrite")
      .csv("output/path")

If your result is an array you should use language specific solution, not spark dataframe api. Because all these kind of results return driver machine.

The command to change the shell at startup is chsh -s <path_to_shell>. The default shells in mac OS X are installed inside the bin directory so if you want to change to the default zsh then you would use the following

chsh -s /bin/zsh

If you're using different version of zsh then you might have to add that version to /etc/shells to avoid the nonstandard shell message. For example if you want home-brew's version of zsh then you have to add /usr/local/bin/zsh to the aforementioned file which you can do in one command sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells" and then run

chsh -s /usr/local/bin/zsh

Or if you want to do the whole thing in one command just copy and paste this if you have zsh already installed

sudo sh -c "echo '/usr/local/bin/zsh' >> /etc/shells" && chsh -s /usr/local/bin/zsh

Compared to the first answer, I will recommend to use dt.strftime() first, then pd.to_datetime(). In this way, it will still result in the datetime data type.

For example,

import pandas as pd

df = pd.DataFrame({'DOB': {0: '26/1/2016 ', 1: '26/1/2016 '})
print(df.dtypes)

df['DOB1'] = df['DOB'].dt.strftime('%m/%d/%Y')
print(df.dtypes)

df['DOB1'] = pd.to_datetime(df['DOB1'])
print(df.dtypes)

I was inspired of Jason's function and made a little improvements to it and got as a result rather fast finder:

function timo_longest(a) {
  var c = 0, d = 0, l = 0, i = a.length;
  if (i) while (i--) {
    d = a[i].length;
    if (d > c) {
      l = i; c = d;
    }
  }
  return a[l];
}
arr=["First", "Second", "Third"];
var longest = timo_longest(arr);

Source: https://github.com/codepath/android_guides/wiki/Understanding-the-Android-Application-Class

In many apps, there's no need to work with an application class directly. However, there are a few acceptable uses of a custom application class:

• Specialized tasks that need to run before the creation of your first activity
• Global initialization that needs to be shared across all components (crash reporting, persistence)
• Static methods for easy access to static immutable data such as a shared network client object

You should never store mutable instance data inside the Application object because if you assume that your data will stay there, your application will inevitably crash at some point with a NullPointerException. The application object is not guaranteed to stay in memory forever, it will get killed. Contrary to popular belief, the app won’t be restarted from scratch. Android will create a new Application object and start the activity where the user was before to give the illusion that the application was never killed in the first place.

It is not possible directly. You may as well write some preprocessor which can handle that.

If I understand it correctly then below are the things that can be helpful to achieve that:

• Use a pre-processor which will run through your JS files for example looking for patterns like "@import somefile.js" and replace them with the content of the actual file. Nicholas Zakas(Yahoo) wrote one such library in Java which you can use (http://www.nczonline.net/blog/2009/09/22/introducing-combiner-a-javascriptcss-concatenation-tool/)

• If you are using Ruby on Rails then you can give Jammit asset packaging a try, it uses assets.yml configuration file where you can define your packages which can contain multiple files and then refer them in your actual webpage by the package name.

• Try using a module loader like RequireJS or a script loader like LabJs with the ability to control the loading sequence as well as taking advantage of parallel downloading.

JavaScript currently does not provide a "native" way of including a JavaScript file into another like CSS ( @import ), but all the above mentioned tools/ways can be helpful to achieve the DRY principle you mentioned. I can understand that it may not feel intuitive if you are from a Server-side background but this is the way things are. For front-end developers this problem is typically a "deployment and packaging issue".

Hope it helps.

Format

Here is the format of the Dockerfile:

We can use # for commenting purpose#Comment for example

#FROM microsoft/aspnetcore
FROM microsoft/dotnet
COPY /publish /app
WORKDIR /app
ENTRYPOINT ["dotnet", "WebApp.dll"]

From the above file when we build the docker, it skips the first line and goes to the next line because we have commented it using #

Let me recommend you using Selenide library. It allows writing much more concise and readable tests. It can wait for presence of elements with much shorter syntax:

$("#elementId").shouldBe(visible);

Here is a sample project for testing Google search: https://github.com/selenide-examples/google

Here is an easy way to do it.

// echo get_header('X-Requested-With');
function get_header($field) {
    $headers = headers_list();
    foreach ($headers as $header) {
        list($key, $value) = preg_split('/:\s*/', $header);
        if ($key == $field)
            return $value;
    }
}

You can define a class or id for input fields.

Or

input {
    line-height: 20px;
}

Hope this helps you.

I enjoy the classic "what's the difference between a LinkedList and an ArrayList (or between a linked list and an array/vector) and why would you choose one or the other?"

The kind of answer I hope for is one that includes discussion of:

• insertion performance
• iteration performance
• memory allocation/reallocation impact
• impact of removing elements from the beginning/middle/end
• how knowing (or not knowing) the maximum size of the list can affect the decision

Is too simple by using the Windows Explorer search inside the project folder. Done.

How about using sort?

dir /b /s | sort

Here's an example I tested with:

dir /s /b /o:gn

d:\root0
d:\root0\root1
d:\root0\root1\folderA
d:\root0\root1\folderB
d:\root0\root1\file00.txt
d:\root0\root1\file01.txt
d:\root0\root1\folderA\fileA00.txt
d:\root0\root1\folderA\fileA01.txt
d:\root0\root1\folderB\fileB00.txt
d:\root0\root1\folderB\fileB01.txt

dir /s /b | sort

d:\root0
d:\root0\root1
d:\root0\root1\file00.txt
d:\root0\root1\file01.txt
d:\root0\root1\folderA
d:\root0\root1\folderA\fileA00.txt
d:\root0\root1\folderA\fileA01.txt
d:\root0\root1\folderB
d:\root0\root1\folderB\fileB00.txt
d:\root0\root1\folderB\fileB01.txt

To just get directories, use the /A:D parameter:

dir /a:d /s /b | sort

If you want to insert this formula =SUMIFS(B2:B10,A2:A10,F2) into cell G2, here is how I did it.

Range("G2")="=sumifs(B2:B10,A2:A10," & _

"F2)"

To split a line of code, add an ampersand, space and underscore.

You can solve the problem by checking if your date matches a REGEX pattern. If not, then NULL (or something else you prefer).

In my particular case it was necessary because I have >20 DATE columns saved as CHAR, so I don't know from which column the error is coming from.

Returning to your query:

1. Declare a REGEX pattern.
It is usually a very long string which will certainly pollute your code (you may want to reuse it as well).

define REGEX_DATE = "'your regex pattern goes here'"

Don't forget a single quote inside a double quote around your Regex :-)

A comprehensive thread about Regex date validation you'll find here.

2. Use it as the first CASE condition:

To use Regex validation in the SELECT statement, you cannot use REGEXP_LIKE (it's only valid in WHERE. It took me a long time to understand why my code was not working. So it's certainly worth a note.

Instead, use REGEXP_INSTR
For entries not found in the pattern (your case) use REGEXP_INSTR (variable, pattern) = 0 .

    DEFINE REGEX_DATE = "'your regex pattern goes here'"

    SELECT   c.contract_num,
         CASE
            WHEN REGEXP_INSTR(c.event_dt, &REGEX_DATE) = 0 THEN NULL
            WHEN   (  MAX (TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
                    - MIN (TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
                 / COUNT (c.event_occurrence) < 32
            THEN
              'Monthly'
            WHEN       (  MAX (
                            TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
                        - MIN (
                            TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
                     / COUNT (c.event_occurrence) >= 32
                 AND   (  MAX (
                            TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD'))
                        - MIN (
                            TO_CHAR (TO_DATE (c.event_dt, 'YYYY-MM-DD'), 'MMDD')))
                     / COUNT (c.event_occurrence) < 91
            THEN
              'Quarterley'
            ELSE
              'Yearly'
         END

I tried to update a field with

$table->update(['field' => 'val']);

But it wasn't working, i had to modify my table Model to authorize this field to be edited : add 'field' in the array "protected $fillable"

Hope it will help someone :)

The way I use these operators:

||, && are for boolean logic. or, and are for control flow. E.g.

do_smth if may_be || may_be -- we evaluate the condition here

do_smth or do_smth_else -- we define the workflow, which is equivalent to do_smth_else unless do_smth

to give a simple example:

> puts "a" && "b"
b

> puts 'a' and 'b'
a

A well-known idiom in Rails is render and return. It's a shortcut for saying return if render, while render && return won't work. See "Avoiding Double Render Errors" in the Rails documentation for more information.

I found this simple method to work the best. It does not rewrite history and all previous check-ins of branch will be appended to the master. Nothing is lost, and you can clearly see what transpired in the commit log.

Objective: Make current state of "branch" the "master"

Working on a branch, commit and push your changes to make sure your local and remote repositories are up to date:

git checkout master      # Set local repository to master
git reset --hard branch  # Force working tree and index to branch
git push origin master    # Update remote repository

After this, your master will be the exact state of your last commit of branch and your master commit log will show all check-ins of the branch.

You can use nested ternary if statements.

# if-else ternary construct
country_code = 'USA'
is_USA = True if country_code == 'USA' else False
print('is_USA:', is_USA)

# if-elif-else ternary construct
# Create function to avoid repeating code.
def get_age_category_name(age):
    age_category_name = 'Young' if age <= 40 else ('Middle Aged' if age > 40 and age <= 65 else 'Senior')
    return age_category_name

print(get_age_category_name(25))
print(get_age_category_name(50))
print(get_age_category_name(75))

First, the headline. You don't need modulo arithmetic to wrap the buffer if you use bit ints to hold the head & tail "pointers", and size them so they are perfectly in synch. IE: 4096 stuffed into a 12-bit unsigned int is 0 all by itself, unmolested in any way. Eliminating modulo arithmetic, even for powers of 2, doubles the speed - almost exactly.

10 million iterations of filling and draining a 4096 buffer of any type of data elements takes 52 seconds on my 3rd Gen i7 Dell XPS 8500 using Visual Studio 2010's C++ compiler with default inlining, and 1/8192nd of that to service a datum.

I'd RX rewriting the test loops in main() so they no longer control the flow - which is, and should be, controlled by the return values indicating the buffer is full or empty, and the attendant break; statements. IE: the filler and drainer should be able to bang against each other without corruption or instability. At some point I hope to multi-thread this code, whereupon that behavior will be crucial.

The QUEUE_DESC (queue descriptor) and initialization function forces all buffers in this code to be a power of 2. The above scheme will NOT work otherwise. While on the subject, note that QUEUE_DESC is not hard-coded, it uses a manifest constant (#define BITS_ELE_KNT) for its construction. (I'm assuming a power of 2 is sufficient flexibility here)

To make the buffer size run-time selectable, I tried different approaches (not shown here), and settled on using USHRTs for Head, Tail, EleKnt capable of managing a FIFO buffer[USHRT]. To avoid modulo arithmetic I created a mask to && with Head, Tail, but that mask turns out to be (EleKnt -1), so just use that. Using USHRTS instead of bit ints increased performance ~ 15% on a quiet machine. Intel CPU cores have always been faster than their buses, so on a busy, shared machine, packing your data structures gets you loaded and executing ahead of other, competing threads. Trade-offs.

Note the actual storage for the buffer is allocated on the heap with calloc(), and the pointer is at the base of the struct, so the struct and the pointer have EXACTLY the same address. IE; no offset required to be added to the struct address to tie up registers.

In that same vein, all of the variables attendant with servicing the buffer are physically adjacent to the buffer, bound into the same struct, so the compiler can make beautiful assembly language. You'll have to kill the inline optimization to see any assembly, because otherwise it gets crushed into oblivion.

To support the polymorphism of any data type, I've used memcpy() instead of assignments. If you only need the flexibility to support one random variable type per compile, then this code works perfectly.

For polymorphism, you just need to know the type and it's storage requirement. The DATA_DESC array of descriptors provides a way to keep track of each datum that gets put in QUEUE_DESC.pBuffer so it can be retrieved properly. I'd just allocate enough pBuffer memory to hold all of the elements of the largest data type, but keep track of how much of that storage a given datum is actually using in DATA_DESC.dBytes. The alternative is to reinvent a heap manager.

This means QUEUE_DESC's UCHAR *pBuffer would have a parallel companion array to keep track of data type, and size, while a datum's storage location in pBuffer would remain just as it is now. The new member would be something like DATA_DESC *pDataDesc, or, perhaps, DATA_DESC DataDesc[2^BITS_ELE_KNT] if you can find a way to beat your compiler into submission with such a forward reference. Calloc() is always more flexible in these situations.

You'd still memcpy() in Q_Put(),Q_Get, but the number of bytes actually copied would be determined by DATA_DESC.dBytes, not QUEUE_DESC.EleBytes. The elements are potentially all of different types/sizes for any given put or get.

I believe this code satisfies the speed and buffer size requirements, and can be made to satisfy the requirement for 6 different data types. I've left the many test fixtures in, in the form of printf() statements, so you can satisfy yourself (or not) that the code works properly. The random number generator demonstrates that the code works for any random head/tail combo.

    printf("\nQueue time was %5.3f to fill & drain %i element queue  %i times \n", 
                     (dbl)(clock()-start)/(dbl)CLOCKS_PER_SEC,Q->EleKnt, LoopKnt);
    printf("\nQueue head value is %i, tail is %i\n", Q->Head, Q->Tail);
    getchar();
    return 0;
}

You can use visual studio 2015. Go to Tools => SQL server => New Data comparison

Select source and target Database.

Just add the document ready function, this way it waits until the DOM has been loaded, also by using the :visible pseudo you can write a simple show and hide function.

Sample

 $(document).ready(function(){

    $( '.expand' ).click(function() {
         if($( '.img_display_content' ).is(":visible")){
              $( '.img_display_content' ).hide();
         } else{
              $( '.img_display_content' ).show();
         }

    });
});

Right after oppening script tag just add import someImage from '../assets/someImage.png' and use it for an icon url iconUrl: someImage

__PRETTY_FUNCTION__ handles C++ features: classes, namespaces, templates and overload

main.cpp

#include <iostream>

namespace N {
    class C {
        public:
            template <class T>
            static void f(int i) {
                (void)i;
                std::cout << "__func__            " << __func__ << std::endl
                          << "__FUNCTION__        " << __FUNCTION__ << std::endl
                          << "__PRETTY_FUNCTION__ " << __PRETTY_FUNCTION__ << std::endl;
            }
            template <class T>
            static void f(double f) {
                (void)f;
                std::cout << "__PRETTY_FUNCTION__ " << __PRETTY_FUNCTION__ << std::endl;
            }
    };
}

int main() {
    N::C::f<char>(1);
    N::C::f<void>(1.0);
}

Compile and run:

g++ -ggdb3 -O0 -std=c++11 -Wall -Wextra -pedantic -o main.out main.cpp
./main.out

Output:

__func__            f
__FUNCTION__        f
__PRETTY_FUNCTION__ static void N::C::f(int) [with T = char]
__PRETTY_FUNCTION__ static void N::C::f(double) [with T = void]

C++20 std::source_location::function_name

http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2019/p1208r5.pdf went into C++20, so we have yet another way to do it.

The documentation says:

constexpr const char* function_name() const noexcept;

6 Returns: If this object represents a position in the body of a function, returns an implementation-defined NTBS that should correspond to the function name. Otherwise, returns an empty string.

where NTBS means "Null Terminated Byte String".

I'll give it a try when support arrives to GCC, GCC 9.1.0 with g++-9 -std=c++2a still doesn't support it.

https://en.cppreference.com/w/cpp/utility/source_location claims usage will be like:

#include <iostream>
#include <string_view>
#include <source_location>
 
void log(std::string_view message,
         const std::source_location& location std::source_location::current()
) {
    std::cout << "info:"
              << location.file_name() << ":"
              << location.line() << ":"
              << location.function_name() << " "
              << message << '\n';
}
 
int main() {
    log("Hello world!");
}

Possible output:

info:main.cpp:16:main Hello world!

so note how this returns the caller information, and is therefore perfect for usage in logging, see also: Is there a way to get function name inside a C++ function?

Dinqyjs has a linq-like syntax and provides polyfills for functions like map and indexOf, and has been designed specifically for working with arrays in Javascript.

Working with large models were very slow before the SP1, (have not tried it after the SP1, but it is said that is a snap now).

I still Design my tables first, then an in-house built tool generates the POCOs for me, so it takes the burden of doing repetitive tasks for each poco object.

when you are using source control systems, you can easily follow the history of your POCOs, it is not that easy with designer generated code.

I have a base for my POCO, which makes a lot of things quite easy.

I have views for all of my tables, each base view brings basic info for my foreign keys and my view POCOs derive from my POCO classes, which is quite usefull again.

And finally I dont like designers.

import urllib

def fetch_thing(url, params, method):
    params = urllib.urlencode(params)
    if method=='POST':
        f = urllib.urlopen(url, params)
    else:
        f = urllib.urlopen(url+'?'+params)
    return (f.read(), f.code)


content, response_code = fetch_thing(
                              'http://google.com/', 
                              {'spam': 1, 'eggs': 2, 'bacon': 0}, 
                              'GET'
                         )

[Update]

Some of these answers are old. Today I would use the requests module like the answer by robaple.

You should be able to solve this problem with one cte view and one batch file containing the bcp code. First create the view. Since, it's relatively straightforward, I did not create a temporary table. Normally I do

CREATE VIEW [dbo].[vwxMySAMPLE_EXTRACT_COLUMNS]
  AS
    WITH MYBCP_CTE (COLUMN_NM, ORD_POS, TXT)
     AS
      ( SELECT  COLUMN_NAME
             , ORDINAL_POSITION
             , CAST(COLUMN_NAME AS VARCHAR(MAX))
        FROM [INFORMATION_SCHEMA].[COLUMNS]
        WHERE TABLE_NAME = 'xMySAMPLE_EXTRACT_NEW'
        AND ORDINAL_POSITION = 1

        UNION ALL

        SELECT  V.COLUMN_NAME
              , V.ORDINAL_POSITION
              , CAST(C.TXT + '|' + V.COLUMN_NAME AS VARCHAR(MAX))
        FROM [INFORMATION_SCHEMA].[COLUMNS]  V INNER JOIN MYBCP_CTE C
        ON V.ORDINAL_POSITION = C.ORD_POS+1
        AND V.ORDINAL_POSITION > 1
        WHERE TABLE_NAME = 'xMySAMPLE_EXTRACT_NEW'
      )

      SELECT CC.TXT
      FROM MYBCP_CTE CC INNER JOIN ( SELECT MAX(ORD_POS) AS MX_CNT
                                     FROM MYBCP_CTE C
                                    ) SC
      ON CC.ORD_POS = SC.MX_CNT

Now, create the batch file. I created this in my Temp directory, but I'm lazy.

  cd\
  CD "C:\Program Files\Microsoft SQL Server\110\Tools\Binn"

  set buildhour=%time: =0%
  set buildDate=%DATE:~4,10%
  set backupfiledate=%buildDate:~6,4%%buildDate:~0,2%%buildDate:~3,2%%time:~0,2%%time:~3,2%%time:~6,2%

  echo %backupfiledate%
  pause

The above code just creates a date to append to the end of your file... Next, the first bcp statement with the view to the recursive cte to concatenate it all together.

  bcp "SELECT *  FROM [dbo].[vwxMYSAMPLE_EXTRACT_COLUMNS] OPTION (MAXRECURSION 300)" queryout C:\Temp\Col_NM%backupfiledate%.txt -c -t"|" -S MYSERVERTOLOGINTO -T -q
  bcp "SELECT *  FROM [myDBName].[dbo].[vwxMYSAMPLE_EXTRACT_NEW] " queryout C:\Temp\3316_PHYSDATA_ALL%backupfiledate%.txt -c -t"|" -S MYSERVERTOLOGINTO -T -q

Now merge them together using the copy command:

  copy C:\Temp\Col_NM%backupfiledate%.txt  + C:\Temp\3316_PHYSDATA_ALL%backupfiledate%.txt  C:\Temp\3316_PHYSDATA_ALL%backupfiledate%.csv

All set

List<Object> objects = new ArrayList<Object>();

objects list will accept any of the Object

You could design like as follows

public class BaseEmployee{/* stuffs */}

public class RegularEmployee extends BaseEmployee{/* stuffs */}

public class Contractors extends BaseEmployee{/* stuffs */}

and in list

List<? extends BaseEmployee> employeeList = new ArrayList<? extends BaseEmployee>();

If you know the the name of the file and if you always want to download that specific file, then you can easily get the ID and other attributes for your desired file from: https://developers.google.com/drive/v2/reference/files/list (towards the bottom you will find a way to run queries). In the q field enter title = 'your_file_name' and run it. You should see some result show up right below and within it should be an "id" field. That is the id you are looking for.

You can also play around with additional parameters from: https://developers.google.com/drive/search-parameters

EDIT: 2014-04-09: As I gained reputations, I feel sorry because I don't use this trick any more. I recommend Kyle's answer. Also notice that the self of self.navigationItem.backBarButtonItem isn't the view controller the back button is displayed, but the previous view controller to be went back.

If you don't need to have title text for the previous view controller, just fill the title with a blank string;

self.navigationItem.title = @"";
[self.navigationController pushViewController:viewController animated:YES];

This will prevent showing "back" with chevron on the pushed view controller.

EDIT: Even you use non-blank title text, setting the title of the previous view controller in viewWillAppear: works except the title can flicker in a blink when view controller popped. I think "The twitter app" seems to do more subtle hack to avoid the flicker.

You see the two empty -D entries in the g++ command line? They're causing the problem. You must have values in the -D items e.g. -DWIN32

if you're insistent on using something like -D$(SYSTEM) -D$(ENVIRONMENT) then you can use something like:

SYSTEM ?= generic
ENVIRONMENT ?= generic

in the makefile which gives them default values.

Your output looks to be missing the all important output:

<command-line>:0:1: error: macro names must be identifiers
<command-line>:0:1: error: macro names must be identifiers

just to clarify, what actually got sent to g++ was -D -DWindows_NT, i.e. define a preprocessor macro called -DWindows_NT; which is of course not a valid identifier (similarly for -D -I.)

In case you closed multiple projects and trying to re-open all of them then in Project Explorer, select all projects. Go to Project -> Open Project.

After ~7 year, I will update it to better approach which is suggested by Bozho.

File theDir = new File("/path/directory");
if (!theDir.exists()){
    theDir.mkdirs();
}

It's also used in regular expressions, meaning "at most one repetition of the preceding character"

for example the regular expression /hey?/ matches with the strings "he" and "hey".

This is a big gray area in cookie SOP (Same Origin Policy).

Theoretically, you can specify port number in the domain and the cookie will not be shared. In practice, this doesn't work with several browsers and you will run into other issues. So this is only feasible if your sites are not for general public and you can control what browsers to use.

The better approach is to get 2 domain names for the same IP and not relying on port numbers for cookies.

Try this :

pip install webdriver-manager

from selenium import webdriver
from webdriver_manager.chrome import ChromeDriverManager

driver = webdriver.Chrome(ChromeDriverManager().install())

I was researching this a while ago because I wanted to create a custom button that would open the file dialog and start the upload immediately. I just noticed something that might make this possible - firefox seems to open the dialog when you click anywhere on the upload. So the following might do it:

1. Create a file upload and a separate element containing an image that you want to use as the button
2. Arrange them to overlap and make the file element backgroud and border transparent so the button is the only thing visible
3. Add the javascript to make IE open the dialog when the button/file input is clicked
4. Use an onchange event to submit the form when a file is selected

This is only theoretical since I already used another method to solve the problem but it just might work.

No -P needed; -E is sufficient:

grep -E '(^|\s)abc(\s|$)' 

or even without -E:

grep '\(^\|\s\)abc\(\s\|$\)' 

Now there is the pandas_profiling package, which is a more complete alternative to df.describe().

If your pandas dataframe is df, the below will return a complete analysis including some warnings about missing values, skewness, etc. It presents histograms and correlation plots as well.

import pandas_profiling
pandas_profiling.ProfileReport(df)

See the example notebook detailing the usage.

If you're attempting to get an element you can use Vue.util.query which is really just a wrapper around document.querySelector but at 14 characters vs 22 characters (respectively) it is technically shorter. It also has some error handling in case the element you're searching for doesn't exist.

There isn't any official documentation on Vue.util, but this is the entire source of the function:

function query(el) {
  if (typeof el === 'string') {
    var selector = el;
    el = document.querySelector(el);
    if (!el) {
      ({}).NODE_ENV !== 'production' && warn('Cannot find element: ' + selector);
    }
  }
  return el;
}

Repo link: Vue.util.query

On SuSE, there are two different configuration files for PHP: one for Apache, and one for CLI (command line interface). In the /etc/php5/ directory, you will find an "apache2" directory and a "cli" directory. Each has a "php.ini" file. The files are for the same purpose (php configuration), but apply to the two different ways of running PHP. These files, among other things, load the modules PHP uses.

If your OS is similar, then these two files are probably not the same. Your Apache php.ini is probably loading the gearman module, while the cli php.ini isn't. When the module was installed (auto or manual), it probably only updated the Apache php.ini file.

You could simply copy the Apache php.ini file over into the cli directory to make the CLI environment exactly like the Apache environment.

Or, you could find the line that loads the gearman module in the Apache file and copy/paste just it to the CLI file.

I have always taken it to mean absent. Here are four cases in the C language that matches to this use of absent

• R f(void) - Function parameters are absent
• void f(P) - Return value is absent
• void *p - Type of what is pointed to is absent
• (void) p - Usage of value is absent

Other C descendants use it for other things. The D programming language uses it for cases where an initializer is absent

• T t = void; - initializing value is absent

In my case, I was transport class component from parent and use it inside as a prop var, using typescript and Formik, and run well like this:

Parent 1

import Parent2 from './../components/Parent2/parent2'
import Parent3 from './../components/Parent3/parent3'

export default class Parent1 extends React.Component {
  render(){
    <React.Fragment>
      <Parent2 componentToFormik={Parent3} />
    </React.Fragment>
  }
}

Parent 2

export default class Parent2 extends React.Component{
  render(){
    const { componentToFormik } = this.props
    return(
    <Formik 
      render={(formikProps) => {
        return(
          <React.fragment>
            {(new componentToFormik(formikProps)).render()}
          </React.fragment>
        )
      }}
    />
    )
  }
}

You should use the sessionStorage instead if you want the key to be deleted when the browser close.

Anyone who says that getting the current time in Google Sheets is not unique to Google's scripting environment obviously has never used Google Apps Script.

That being said, do you want to return current time as to what? The script user's timezone? The script owner's timezone?

The script timezone is set in the Script Editor, by the script owner. But different authorized users of the script can set timezone for the spreadsheet they are using from File/Spreadsheet settings menu of Google Sheets.

I guess you want the first option. You can use the built in function to get the spreadsheet timezone, and then use the Utilities class to format date.

var timezone = SpreadsheetApp.getActive().getSpreadsheetTimeZone();

var date = Utilities.formatDate(new Date(), SpreadsheetApp.getActive().getSpreadsheetTimeZone(), "EEE, d MMM yyyy HH:mm")

Alternatively, get the timezone offset from UTC time using Javascript's date method, format the timezone, and pass it into Utilities.formatDate().

This requires one minor adjustment though. The offset returned by getTimezoneOffset() runs contradictory to how we often think of timezone. If the offset is positive, the local timezone is behind UTC, like US timezones. If the offset is negative, the local timezone is ahead UTC, like Asia/Bangkok, Australian Eastern Standard Time etc.

const now = new Date();
// getTimezoneOffset returns the offset in minutes, so we have to divide it by 60 to get the hour offset.
const offset = now.getTimezoneOffset() / 60
// Change the sign of the offset and format it
const timeZone = "GMT+" + offset * (-1) 
Logger.log(Utilities.formatDate(now, timeZone, 'EEE, d MMM yyyy HH:mm');

You can fetch the connection string by using below line of code -

using System; using System.Configuration;

var connectionString=ConfigurationManager.ConnectionStrings["MyConnectionString"].ConnectionString;

Here is a reference : Connection String from App.config

To account for leading and trailing whitespace, you probably want to use normalize-space()

//div[contains(@class, 'Caption') and normalize-space(.)='Model saved']

and

//div[@id='alertLabel' and normalize-space(.)='Save to server successful']

Note that //div[contains(@class, 'Caption') and normalize-space(.//text())='Model saved'] also works.

As others mentioned, Justin's answer was close, but not quite right. I tested this using Visual Studio's "Paste JSON as C# Classes"

{
    "foos" : [
        {
            "prop1":"value1",
            "prop2":"value2"
        },
        {
            "prop1":"value3", 
            "prop2":"value4"
        }
    ]
}

Yes, Use jspdf To create a pdf file.

You can then turn it into a data URI and inject a download link into the DOM

You will however need to write the HTML to pdf conversion yourself.

Just use printer friendly versions of your page and let the user choose how he wants to print the page.

Edit: Apparently it has minimal support

So the answer is write your own PDF writer or get a existing PDF writer to do it for you (on the server).

You could also use matrix multiplication (aka dot product):

a = [[1,2,3],[4,5,6],[7,8,9]]
b = [0,1,2]
c = numpy.diag(b)

numpy.dot(c,a)

Which is more elegant is probably a matter of taste.

A CDATA section is "a section of element content that is marked for the parser to interpret as only character data, not markup."

Syntactically, it behaves similarly to a comment:

<exampleOfAComment>
<!--
    Since this is a comment
    I can use all sorts of reserved characters
    like > < " and &
    or write things like
    <foo></bar>
    but my document is still well-formed!
-->
</exampleOfAComment>

... but it is still part of the document:

<exampleOfACDATA>
<![CDATA[
    Since this is a CDATA section
    I can use all sorts of reserved characters
    like > < " and &
    or write things like
    <foo></bar>
    but my document is still well formed!
]]>
</exampleOfACDATA>

Try saving the following as a .xhtml file (not .html) and open it using FireFox (not Internet Explorer) to see the difference between the comment and the CDATA section; the comment won't appear when you look at the document in a browser, while the CDATA section will:

<?xml version="1.0" encoding="UTF-8" standalone="no" ?>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en" >
<head>
<title>CDATA Example</title>
</head>
<body>

<h2>Using a Comment</h2>
<div id="commentExample">
<!--
You won't see this in the document
and can use reserved characters like
< > & "
-->
</div>

<h2>Using a CDATA Section</h2>
<div id="cdataExample">
<![CDATA[
You will see this in the document
and can use reserved characters like
< > & "
]]>
</div>

</body>
</html>

Something to take note of with CDATA sections is that they have no encoding, so there's no way to include the string ]]> in them. Any character data which contains ]]> will have to - as far as I know - be a text node instead. Likewise, from a DOM manipulation perspective you can't create a CDATA section which includes ]]>:

var myEl = xmlDoc.getElementById("cdata-wrapper");
myEl.appendChild(xmlDoc.createCDATASection("This section cannot contain ]]>"));

This DOM manipulation code will either throw an exception (in Firefox) or result in a poorly structured XML document: http://jsfiddle.net/9NNHA/

You can simulate them for example with hashes, but need care about the leading zeroes and many other things. The next demonstration works, but it is far from optimal solution.

#!/bin/bash
declare -A matrix
num_rows=4
num_columns=5

for ((i=1;i<=num_rows;i++)) do
    for ((j=1;j<=num_columns;j++)) do
        matrix[$i,$j]=$RANDOM
    done
done

f1="%$((${#num_rows}+1))s"
f2=" %9s"

printf "$f1" ''
for ((i=1;i<=num_rows;i++)) do
    printf "$f2" $i
done
echo

for ((j=1;j<=num_columns;j++)) do
    printf "$f1" $j
    for ((i=1;i<=num_rows;i++)) do
        printf "$f2" ${matrix[$i,$j]}
    done
    echo
done

the above example creates a 4x5 matrix with random numbers and print it transposed, with the example result

           1         2         3         4
 1     18006     31193     16110     23297
 2     26229     19869      1140     19837
 3      8192      2181     25512      2318
 4      3269     25516     18701      7977
 5     31775     17358      4468     30345

The principle is: Creating one associative array where the index is an string like 3,4. The benefits:

• it's possible to use for any-dimension arrays ;) like: 30,40,2 for 3 dimensional.
• the syntax is close to "C" like arrays ${matrix[2,3]}

If you write a comment in a line with a code, you must write a comment, leaving 2 spaces before the # sign and 1 space before the # sign

print("Hello World")  # printing

If you write a comment on a new line, you must write a comment, leaving 1 space kn in the # sign

# single line comment

To write comments longer than 1 line, you use 3 quotes

"""
This is a comment
written in
more than just one line
"""

I know its late but i recently ran into this situation. After wasting entire day I finally found the solution. I am suprised that I got this info on oracle's website whereas this seems nowhere to be found on IBM's website.

If you want to use JDBC drivers for DB2 that are compatible with JDK 1.5 or 1.4 , you need to use the jar db2jcc.jar, which is available in SQLLIB/java/ folder of your db2 installation.

You can check my.ini file to see where the data folder is located.

Usually there is a folder {mysqlDirectory}/data

MySQL data storage:

Commands.frm
Commands.myd
Commands.myi

The *.frm files contain the table definitions. Your *.myi files are MyISAM index files. Your *.myd files contain the table data.

Edit/Update. Because of the interest shown in the question here is more info which is found also in the comments.

In Windows 8.1, the MySQL databases are stored (by default) here: C:\ProgramData\MySQL\MySQL Server 5.6\data

The folder C:\ProgramData is a hidden folder, so you must type it into Windows Explorer address to get there. In that data folder, the databases are named /{database_name_folder}/{database_tables_and_files}.

For instance,

C:\ProgramData\MySQL\MySQL Server 5.6\data\mydatabase\mytable.frm
C:\ProgramData\MySQL\MySQL Server 5.6\data\mydatabase\mytable.ibd 

Thank @marty-mcgee for this content

I guess the problem is that you need to start a separate thread for each connection and call serverSocket.accept() in a loop to accept more than one connection.

It is not a problem to have more than one connection on the same port.

sudo mv /filename /etc/init.d/
sudo chmod +x /etc/init.d/filename 
sudo update-rc.d filename defaults 

Script should now start on boot. Note that this method also works with both hard links and symbolic links (ln).

Edit

At this point in the boot process PATH isn't set yet, so it is critical that absolute paths are used throughout. BUT, as pointed out in the comments by Steve HHH, explicitly declaring the full file path (/etc/init.d/filename) for the update-rc.d command is not valid in most versions of Linux. Per the manpage for update-rc.d, the second parameter is a script located in /etc/init.d/*. Updated above code to reflect this.

Another Edit

Also as pointed out in the comments (by Charles Brandt), /filename must be an init style script. A good template was also provided - https://github.com/fhd/init-script-template.

Another link to another article just to avoid possible link rot (although it would be saddening if GitHub died) - http://www.linux.com/learn/tutorials/442412-managing-linux-daemons-with-init-scripts

yetAnother Edit

As pointed out in the comments (by Russell Yan), This works only on default mode of update-rc.d.

According to manual of update-rc.d, it can run on two modes, "the machines using the legacy mode will have a file /etc/init.d/.legacy-bootordering", in which case you have to pass sequence and runlevel configuration through command line arguments.

The equivalent argument set for the above example is

sudo update-rc.d filename start 20 2 3 4 5 . stop 20 0 1 6 .

as far as we want to send all the form input fields which have name attribute, you can do this for all forms, regardless of the field names:

First Solution

function submitForm(form){
    var url = form.attr("action");
    var formData = {};
    $(form).find("input[name]").each(function (index, node) {
        formData[node.name] = node.value;
    });
    $.post(url, formData).done(function (data) {
        alert(data);
    });
}

Second Solution: in this solution you can create an array of input values:

function submitForm(form){
    var url = form.attr("action");
    var formData = $(form).serializeArray();
    $.post(url, formData).done(function (data) {
        alert(data);
    });
}

from s in context.shift
where !context.employeeshift.Any(es=>(es.shiftid==s.shiftid)&&(es.empid==57))
select s;

Hope this helps

toISOString() will give current UTC Date. So to get the current local time we have to get getTimezoneOffset() and subtract it from current time

document.getElementById('dt').max = new Date(new Date().getTime() - new Date().getTimezoneOffset() * 60000).toISOString().split("T")[0];

<input type="date" min='1899-01-01' id="dt" />

Either you have mvn give you the answer (as most answers suggest), or you extract the answer from the pom.xml. The only drawback of the second approach is that you can very easily extract the value of the <version/> tag, but it will be meaningful only if it's literal, that is, not a Maven property. I chose this approach anyway because:

• mvn is way to verbose and I simply don't like filtering its output.
• Starting mvn is very slow compared to reading the pom.xml.
• I always use literal values in <version/>.

mvn-version is a zsh shell script that uses xmlstarlet to read the pom.xml and print the version of the project (if it exists) or the version of the parent project (if it exists):

$ mvn-version .
1.0.0-SNAPSHOT

The advantage is that it's way quicker than running mvn:

$ time mvn-version .
1.1.0-SNAPSHOT
mvn-version .  0.01s user 0.01s system 75% cpu 0.019 total

$ time mvn org.apache.maven.plugins:maven-help-plugin:2.1.1:evaluate \
> -Dexpression=project.version
mvn org.apache.maven.plugins:maven-help-plugin:2.1.1:evaluate   4.17s user 0.21s system 240% cpu 1.823 total

The difference on my machine is greater than two orders of magnitude.

What about the following snippet?

require 'json'
value = '{"val":"test","val1":"test1","val2":"test2"}'
puts JSON.parse(value) # => {"val"=>"test","val1"=>"test1","val2"=>"test2"}

import matplotlib.pyplot as plt
import seaborn as sns

df = sns.load_dataset('iris')
sns_plot = sns.pairplot(df, hue='species', height=2.5)
plt.savefig('output.png')

UPDATE NOTE: size was changed to height.

I also faced that problem and there are two ways to solve this in laravel.

1. first one is you can set the default value as null. I will show you an example:

   public function up()
   {
       Schema::create('users', function (Blueprint $table) {
           $table->increments('id');
           $table->string('name');
           $table->string('gender');
           $table->string('slug');
           $table->string('pic')->nullable();
           $table->string('email')->unique();
           $table->string('password');
           $table->rememberToken();
           $table->timestamps();
       });
   }
   

as the above example, you can set nullable() for that feature. then when you are inserting data MySQL set the default value as null.

2. second one is in your model set your input field in protected $fillable field. as example:

   protected $fillable = [
       'name', 'email', 'password', 'slug', 'gender','pic'
   ];
   

I think the second one is fine than the first one and also you can set nullable feature as well as fillable in the same time without a problem.

completed = (id) => {
    var details = {
        'id': id,

    };

    var formBody = [];
    for (var property in details) {
        var encodedKey = encodeURIComponent(property);
        var encodedValue = encodeURIComponent(details[property]);
        formBody.push(encodedKey + "=" + encodedValue);
    }
    formBody = formBody.join("&");

    fetch(markcompleted, {
        method: 'POST',
        headers: {
            'Accept': 'application/json',
            'Content-Type': 'application/x-www-form-urlencoded'
        },
        body: formBody
    })
        .then((response) => response.json())
        .then((responseJson) => {
            console.log(responseJson, 'res JSON');
            if (responseJson.status == "success") {
                console.log(this.state);
                alert("your todolist is completed!!");
            }
        })
        .catch((error) => {
            console.error(error);
        });
};

You can set UINavigation Background color by using this code in any view controller

self.navigationController.navigationBar.backgroundColor = [UIColor colorWithRed:10.0f/255.0f green:30.0f/255.0f blue:200.0f/255.0f alpha:1.0f];

Use it like this, should work:

 <a routerLink="/Service/Sign_in"><button class="btn btn-success pull-right" > Add Customer</button></a>

You can also use router.navigateByUrl('..') like this:

<button type="button" class="btn btn-primary-outline pull-right" (click)="btnClick();"><i class="fa fa-plus"></i> Add</button>    

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

btnClick= function () {
        this.router.navigateByUrl('/user');
};

Update 1

You have to inject Router in the constructor like this:

constructor(private router: Router) { }

only then you are able to use this.router. Remember also to import RouterModule in your module.

Update 2

Now, After Angular v4 you can directly add routerLink attribute on the button (As mentioned by @mark in comment section) like below (No "'/url?" since Angular 6, when a Route in RouterModule exists) -

 <button [routerLink]="'url'"> Button Label</button>

This should work:

ax1.plot(xtr, color='r', label='HHZ 1')
ax1.legend(loc="upper right")
ax2.plot(xtr, color='r', label='HHN')
ax2.legend(loc="upper right")
ax3.plot(xtr, color='r', label='HHE')
ax3.legend(loc="upper right")

Using issubclass seemed like a clean way to write loglevels. It kinda feels odd using it... but it seems cleaner than other options.

class Error(object): pass
class Warn(Error): pass
class Info(Warn): pass
class Debug(Info): pass

class Logger():
    LEVEL = Info

    @staticmethod
    def log(text,level):
        if issubclass(Logger.LEVEL,level):
            print(text)
    @staticmethod
    def debug(text):
        Logger.log(text,Debug)   
    @staticmethod
    def info(text):
        Logger.log(text,Info)
    @staticmethod
    def warn(text):
        Logger.log(text,Warn)
    @staticmethod
    def error(text):
        Logger.log(text,Error)

jQuery normalises event.which depending on whether event.which, event.keyCode or event.charCode is supported by the browser:

// Add which for key events
if ( event.which == null && (event.charCode != null || event.keyCode != null) ) {
   event.which = event.charCode != null ? event.charCode : event.keyCode;
}

An added benefit of .which is that jQuery does it for mouse clicks too:

// Add which for click: 1 === left; 2 === middle; 3 === right
// Note: button is not normalized, so don't use it
if ( !event.which && event.button !== undefined ) {
    event.which = (event.button & 1 ? 1 : ( event.button & 2 ? 3 : ( event.button & 4 ? 2 : 0 ) ));
}

You can read about jQuery Ajax from official jQuery Site: https://api.jquery.com/jQuery.ajax/

If you don't want to use any click event then you can set timer for periodically update.

Below code may be help you just example.

function update() {
  $.get("response.php", function(data) {
    $("#some_div").html(data);
    window.setTimeout(update, 10000);
  });
}

Above function will call after every 10 seconds and get content from response.php and update in #some_div.

for those looking for a way to mock POST HttpServletRequest with Json payload, the below is in Kotlin, but the key take away here is the DelegatingServetInputStream when you want to mock the request.getInputStream from the HttpServletRequest

@Mock
private lateinit var request: HttpServletRequest

@Mock
private lateinit var response: HttpServletResponse

@Mock
private lateinit var chain: FilterChain

@InjectMocks
private lateinit var filter: ValidationFilter


@Test
fun `continue filter chain with valid json payload`() {
    val payload = """{
      "firstName":"aB",
      "middleName":"asdadsa",
      "lastName":"asdsada",
      "dob":null,
      "gender":"male"
    }""".trimMargin()

    whenever(request.requestURL).
        thenReturn(StringBuffer("/profile/personal-details"))
    whenever(request.method).
        thenReturn("PUT")
    whenever(request.inputStream).
        thenReturn(DelegatingServletInputStream(ByteArrayInputStream(payload.toByteArray())))

    filter.doFilter(request, response, chain)

    verify(chain).doFilter(request, response)
}

I tried many formats, but only that worked:

select /*+INDEX(e,dept_idx)*/ * from emp e;

Just change home to your liking

$home_url = 'http://' . $_SERVER['HTTP_HOST'] . dirname($_SERVER['PHP_SELF']) . '/home';

header('Location: ' . $home_url);

This appears to be a bug in Bundler not recognizing the default gems installed along with ruby 2.x. I still experienced the problem even with the latest version of bundler (1.5.3).

One solution is to simply delete json-1.8.1.gemspec from the default gemspec directory.

rm ~/.rubies/ruby-2.1.0/lib/ruby/gems/2.1.0/specifications/default/json-1.8.1.gemspec

After doing this, bundler should have no problem locating the gem. Note that I am using chruby. If you're using some other ruby manager, you'll have to update your path accordingly.

Some code examples for simple GET request. Maybe this helps understanding the difference. Using then:

$http.get('/someURL').then(function(response) {
    var data = response.data,
        status = response.status,
        header = response.header,
        config = response.config;
    // success handler
}, function(response) {
    var data = response.data,
        status = response.status,
        header = response.header,
        config = response.config;
    // error handler
});

Using success/error:

$http.get('/someURL').success(function(data, status, header, config) {
    // success handler
}).error(function(data, status, header, config) {
    // error handler
});

There is no way that you can do it in PHP when HTML is already generated. What you can do is to use JavaScript or jQuery:

document.getElementById('//ID//').innerHTML="HTML CODE";

If you have to do it when your URI changes you can get the URI and then split it and then insert the HTML in script dynamically:

var url = document.URL;
// to get url and then use split() to check the parameter

On bulk, you can always delete the row before the insert. A deletion of a row that doesn't exist doesn't cause an error, so its safely skipped.

I had this issue when trying to use Maven 3, after upgrading from Ubuntu 16.04 LTS (Xenial Xerus) to Ubuntu 18.04 LTS (Bionic Beaver).

Checking /usr/lib/jvm/java-8-oracle/jre/lib/security showed that my cacerts file was a symbolic link pointing to /etc/ssl/certs/java/cacerts.

I also had a file suspiciously named cacerts.original.

I renamed cacerts.original to cacerts, and that fixed the issue.

Using id for this task is not an option in many cases. For example - table with twitter statuses. Here is a variant with specified timestamp field.

delete from table 
where access_time >= 
(
    select access_time from  
    (
        select access_time from table 
            order by access_time limit 150000,1
    ) foo    
)

and to insert data use the following

 $sql = "INSERT INTO  Table-Name (Column-Name)

.NIT has a limit to the amount of memory it can access of the total. Theres a percentage, and then 2 GB in xp was the hard ceiling.

You could have 4 GB in it, and it would kill the app when it hit 2GB.

Also in 64 bit mode, there is a percentage of memory you can use out of the system, so I'm not sure if you can ask for the whole thing or if this is specifically guarded against.

"2) Can we use Dijksra’s algorithm for shortest paths for graphs with negative weights – one idea can be, calculate the minimum weight value, add a positive value (equal to absolute value of minimum weight value) to all weights and run the Dijksra’s algorithm for the modified graph. Will this algorithm work?"

This absolutely doesn't work unless all shortest paths have same length. For example given a shortest path of length two edges, and after adding absolute value to each edge, then the total path cost is increased by 2 * |max negative weight|. On the other hand another path of length three edges, so the path cost is increased by 3 * |max negative weight|. Hence, all distinct paths are increased by different amounts.

Here, There are two things inside the domain

1. iFrame Section
2. Page Loaded inside the iFrame

So you want to style those two sections as follows,

1. Style for the iFrame Section

It can style using CSS with that respected id or class name. You can just style it in your parent Style sheets also.

<style>
#my_iFrame{
height: 300px;
width: 100%;
position:absolute;
top:0;
left:0;
border: 1px black solid;
}
</style>

<iframe name='iframe1' id="my_iFrame" src="#" cellspacing="0"></iframe>

2. Style the Page Loaded inside the iFrame

This Styles can be loaded from the parent page with the help of Javascript

var cssFile  = document.createElement("link") 
cssFile.rel  = "stylesheet"; 
cssFile.type = "text/css"; 
cssFile.href = "iFramePage.css"; 

then set that CSS file to the respected iFrame section

//to Load in the Body Part
frames['my_iFrame'].document.body.appendChild(cssFile); 
//to Load in the Head Part
frames['my_iFrame'].document.head.appendChild(cssFile);

Here, You can edit the Head Part of the Page inside the iFrame using this way also

var $iFrameHead = $("#my_iFrame").contents().find("head");
$iFrameHead.append(
   $("<link/>",{ 
      rel: "stylesheet", 
      href: urlPath, 
      type: "text/css" }
     ));

I gonna assumed you making a popup with code from WW3 school, correct? check it css. the .modal one, there're already word z-index there. just change from 1 to 100.

.modal {
    display: none; /* Hidden by default */
    position: fixed; /* Stay in place */
    z-index: 1; /* Sit on top */
    padding-top: 100px; /* Location of the box */
    left: 0;
    top: 0;
    width: 100%; /* Full width */
    height: 100%; /* Full height */
    overflow: auto; /* Enable scroll if needed */
    background-color: rgb(0,0,0); /* Fallback color */
    background-color: rgba(0,0,0,0.4); /* Black w/ opacity */
}

Avoid the Date object creation w/ System.currentTimeMillis(). A divide by 1000 gets you to Unix epoch.

As mentioned in a comment, you typically want a primitive long (lower-case-l long) not a boxed object long (capital-L Long) for the unixTime variable's type.

long unixTime = System.currentTimeMillis() / 1000L;

I know this is old, but since Postgresql 9.3 there is an option to use a keyword "LATERAL" to use RELATED subqueries inside of JOINS, so the query from the question would look like:

SELECT 
    name, author_id, count(*), t.total
FROM
    names as n1
    INNER JOIN LATERAL (
        SELECT 
            count(*) as total
        FROM 
            names as n2
        WHERE 
            n2.id = n1.id
            AND n2.author_id = n1.author_id
    ) as t ON 1=1
GROUP BY 
    n1.name, n1.author_id

As recommended by the Tensorflow GPU guide.

# Place tensors on the CPU
with tf.device('/CPU:0'):
  a = tf.constant([[1.0, 2.0, 3.0], [4.0, 5.0, 6.0]])
  b = tf.constant([[1.0, 2.0], [3.0, 4.0], [5.0, 6.0]])
  # Any additional tf code placed in this block will be executed on the CPU

You could use a separate file, like npm_globals.txt, instead of package.json. This file would contain each module on a new line like this,

[email protected]
[email protected]
[email protected]
[email protected]
[email protected]

Then in the command line run,

< npm_globals.txt xargs npm install -g

Check that they installed properly with,

npm list -g --depth=0

As for whether you should do this or not, I think it all depends on use case. For most projects, this isn't necessary; and having your project's package.json encapsulate these tools and dependencies together is much preferred.

But nowadays I find that I'm always installing create-react-app and other CLI's globally when I jump on a new machine. It's nice to have an easy way to install a global tool and its dependencies when versioning doesn't matter much.

And nowadays, I'm using npx, an npm package runner, instead of installing packages globally.

You can use this code for connect and request using http and json

try {
         
        URL url = new URL("https://www.googleapis.com/youtube/v3/playlistItems?part=snippet"
                + "&key="+key
                + "&access_token=" + access_token);
        HttpURLConnection conn = (HttpURLConnection) url.openConnection();
        conn.setDoOutput(true);
        conn.setRequestMethod("POST");
        conn.setRequestProperty("Content-Type", "application/json");
 
        String input = "{ \"snippet\": {\"playlistId\": \"WL\",\"resourceId\": {\"videoId\": \""+videoId+"\",\"kind\": \"youtube#video\"},\"position\": 0}}";
 
        OutputStream os = conn.getOutputStream();
        os.write(input.getBytes());
        os.flush();
 
        if (conn.getResponseCode() != HttpURLConnection.HTTP_CREATED) {
            throw new RuntimeException("Failed : HTTP error code : "
                + conn.getResponseCode());
        }
 
        BufferedReader br = new BufferedReader(new InputStreamReader(
                (conn.getInputStream())));
 
        String output;
        System.out.println("Output from Server .... \n");
        while ((output = br.readLine()) != null) {
            System.out.println(output);
        }
 
        conn.disconnect();
 
      } catch (MalformedURLException e) {
 
        e.printStackTrace();
 
      } catch (IOException e) {
 
        e.printStackTrace();
 
     }

I did it like this:

li {
  list-style: none;
  background-image: url("./assets/img/control.svg");
  background-repeat: no-repeat;
  background-position: left center;
}

Or you can try this if you want to change the color:

li::before {
  content: "";
  display: inline-block;
  height: 10px;
  width: 10px;
  margin-right: 7px;

  background-color: orange;
  -webkit-mask-image: url("./assets/img/control.svg");
  -webkit-mask-size: cover;
}

you may use yourArray.length to findout number of elements in an array.

Make sure yourArray is not null before doing yourArray.length, otherwise you will end up with NullPointerException.

In Linux every process has its own folder in /proc. So you could use getpid() to get the pid of the running process and then join it with the path /proc to get the folder you hopefully need.

Here's a short example in Python:

import os
print os.path.join('/proc', str(os.getpid()))

Here's the example in ANSI C as well:

#include <stdio.h>
#include <stdlib.h>
#include <unistd.h>
#include <sys/types.h>


int
main(int argc, char **argv)
{
    pid_t pid = getpid();

    fprintf(stdout, "Path to current process: '/proc/%d/'\n", (int)pid);

    return EXIT_SUCCESS;
}

Compile it with:

gcc -Wall -Werror -g -ansi -pedantic process_path.c -oprocess_path 

You also can do this directly on Frames

In [104]: df = DataFrame(dict(A = True, B = False),index=range(3))

In [105]: df
Out[105]: 
      A      B
0  True  False
1  True  False
2  True  False

In [106]: df.dtypes
Out[106]: 
A    bool
B    bool
dtype: object

In [107]: df.astype(int)
Out[107]: 
   A  B
0  1  0
1  1  0
2  1  0

In [108]: df.astype(int).dtypes
Out[108]: 
A    int64
B    int64
dtype: object

You can convert a number to ASCII in java. example converting a number 1 (base is 10) to ASCII.

char k = Character.forDigit(1, 10);
System.out.println("Character: " + k);
System.out.println("Character: " + ((int) k));

Output:

Character: 1
Character: 49

This works:

sc.exe config "[servicename]" obj= "[.\username]" password= "[password]"

Where each of the [bracketed] items are replaced with the true arguments. (Keep the quotes, but don't keep the brackets.)

Just keep in mind that:

• The spacing in the above example matters. obj= "foo" is correct; obj="foo" is not.
• '.' is an alias to the local machine, you can specify a domain there (or your local computer name) if you wish.
• Passwords aren't validated until the service is started
• Quote your parameters, as above. You can sometimes get by without quotes, but good luck.

Here's the Javadoc in Oracle's website for the Date class: https://docs.oracle.com/javase/8/docs/api/java/util/Date.html
If you scroll down to "Constructor Summary," you'll see the different options for how a Date object can be instantiated. Like all objects in Java, you create a new one with the following:

Date firstDate = new Date(ConstructorArgsHere);

Now you have a bit of a choice. If you don't pass in any arguments, and just do this,

Date firstDate = new Date();

it will represent the exact date and time at which you called it. Here are some other constructors you may want to make use of:

Date firstDate1 = new Date(int year, int month, int date);
Date firstDate2 = new Date(int year, int month, int date, int hrs, int min);
Date firstDate3 = new Date(int year, int month, int date, int hrs, int min, int sec);

So to make your expression work, changing && for -a will do the trick.

It is correct like this:

 if [ -f $VAR1 ] && [ -f $VAR2 ] && [ -f $VAR3 ]
 then  ....

or like

 if [[ -f $VAR1 && -f $VAR2 && -f $VAR3 ]]
 then  ....

or even

 if [ -f $VAR1 -a -f $VAR2 -a -f $VAR3 ]
 then  ....

You can find further details in this question bash : Multiple Unary operators in if statement and some references given there like What is the difference between test, [ and [[ ?.

Thanks to @ahhmarr's solution I was able to solve the same problem in my Angular+ui-router environment, which I'll share here for whoever's interested.

In my index.html I've added the following script:

<script type="text/javascript">
    setTimeout(function() {
        $('input').attr('autocomplete', 'off');
    }, 2000);
</script>

Then to cover state changes, I've added the following in my root controller:

$rootScope.$on('$stateChangeStart', function() {
                $timeout(function () {
                    $('input').attr('autocomplete', 'off');
                }, 2000);
            });

The timeouts are for the html to render before applying the jquery.

If you find a better solution please let me know.

If you are getting a timeout while on the table designer, change the "Transaction time-out after" value under Tools --> Options --> Designers --> Table and Database Designers

This will get rid of this message: "Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding."

it's simple, use the "-B" option to add .h files' dir to search path.

E.g. g++ -B /header_file.h your.cpp -o bin/your_command

In researching Matt's comment, I have revised my original statement. He is correct, there will be a difference in performance between an inline table valued function (ITVF) and a multi-statement table valued function (MSTVF) even if they both simply execute a SELECT statement. SQL Server will treat an ITVF somewhat like a VIEW in that it will calculate an execution plan using the latest statistics on the tables in question. A MSTVF is equivalent to stuffing the entire contents of your SELECT statement into a table variable and then joining to that. Thus, the compiler cannot use any table statistics on the tables in the MSTVF. So, all things being equal, (which they rarely are), the ITVF will perform better than the MSTVF. In my tests, the performance difference in completion time was negligible however from a statistics standpoint, it was noticeable.

In your case, the two functions are not functionally equivalent. The MSTV function does an extra query each time it is called and, most importantly, filters on the customer id. In a large query, the optimizer would not be able to take advantage of other types of joins as it would need to call the function for each customerId passed. However, if you re-wrote your MSTV function like so:

CREATE FUNCTION MyNS.GetLastShipped()
RETURNS @CustomerOrder TABLE
    (
    SaleOrderID    INT         NOT NULL,
    CustomerID      INT         NOT NULL,
    OrderDate       DATETIME    NOT NULL,
    OrderQty        INT         NOT NULL
    )
AS
BEGIN
    INSERT @CustomerOrder
    SELECT a.SalesOrderID, a.CustomerID, a.OrderDate, b.OrderQty
    FROM Sales.SalesOrderHeader a 
        INNER JOIN Sales.SalesOrderHeader b
            ON a.SalesOrderID = b.SalesOrderID
        INNER JOIN Production.Product c 
            ON b.ProductID = c.ProductID
    WHERE a.OrderDate = (
                        Select Max(SH1.OrderDate)
                        FROM Sales.SalesOrderHeader As SH1
                        WHERE SH1.CustomerID = A.CustomerId
                        )
    RETURN
END
GO

In a query, the optimizer would be able to call that function once and build a better execution plan but it still would not be better than an equivalent, non-parameterized ITVS or a VIEW.

ITVFs should be preferred over a MSTVFs when feasible because the datatypes, nullability and collation from the columns in the table whereas you declare those properties in a multi-statement table valued function and, importantly, you will get better execution plans from the ITVF. In my experience, I have not found many circumstances where an ITVF was a better option than a VIEW but mileage may vary.

Thanks to Matt.

Addition

Since I saw this come up recently, here is an excellent analysis done by Wayne Sheffield comparing the performance difference between Inline Table Valued functions and Multi-Statement functions.

His original blog post.

Copy on SQL Server Central

When the ASP.NET Web API calls a method on a controller, it must set values for the parameters, a process called parameter binding.

By default, Web API uses the following rules to bind parameters:

• If the parameter is a "simple" type, Web API tries to get the value from the URI. Simple types include the .NET primitive types (int, bool, double, and so forth), plus TimeSpan, DateTime, Guid, decimal, and string, plus any type with a type converter that can convert from a string.

• For complex types, Web API tries to read the value from the message body, using a media-type formatter.

So, if you want to override the above default behaviour and force Web API to read a complex type from the URI, add the [FromUri] attribute to the parameter. To force Web API to read a simple type from the request body, add the [FromBody] attribute to the parameter.

So, to answer your question, the need of the [FromBody] and [FromUri] attributes in Web API is simply to override, if necessary, the default behaviour as described above. Note that you can use both attributes for a controller method, but only for different parameters, as demonstrated here.

There is a lot more information on the web if you google "web api parameter binding".

I had the same problem:

tr:hover { background: #000 !important; }

allone did not work, but adding

tr:hover td { background: transparent; }

to the next line of my css did the job for me!! My problem was that some of the TDs already had a background-color assigned and I did not know that I have to set that to TRANSPARENT to make the tr:hover work.

Actually, I used it with a classnames:

.trclass:hover { background: #000 !important; }
.trclass:hover td { background: transparent; }

Thanks for these answers, they made my day!! :)

Reading through this helps solve a similar problem. The data is in decimal datatype - [DOB] [decimal](8, 0) NOT NULL - eg - 19700109. I want to get at the month. The solution is to combine SUBSTRING with CONVERT to VARCHAR.

    SELECT [NUM]
       ,SUBSTRING(CONVERT(VARCHAR, DOB),5,2) AS mob
    FROM [Dbname].[dbo].[Tablename] 

Well...there are several ways to interpret this question.

The first way and the way I think you mean is to simply alter the display size so all images display the same size. For this, I would actually use CSS and not JavaScript. Simply create a class that has the appropriate width and height values set, and make all <img> tags use this class.

A second way is that you want to preserve the aspect ration of all the images, but scale the display size to a sane value. There is a way to access this in JavaScript, but I'll need a bit to write up a quick code sample.

The third way, and I hope you don't mean this way, is to alter the actual size of the image. This is something you'd have to do on the server side, as not only is JavaScript unable to create images, but it wouldn't make any sense, as the full sized image has already been sent.

I had the same problem but caused by including twice bootstrap.js and jquery.js files.

On a single click the event was processed twice by both jquery instances. One closed and one opened the toggle.

Given your current table structure this is not currently possible in DynamoDB. The huge challenge is to understand that the Hash key of the table (partition) should be treated as creating separate tables. In some ways this is really powerful (think of partition keys as creating a new table for each user or customer, etc...).

Queries can only be done in a single partition. That's really the end of the story. This means if you want to query by date (you'll want to use msec since epoch), then all the items you want to retrieve in a single query must have the same Hash (partition key).

I should qualify this. You absolutely can scan by the criterion you are looking for, that's no problem, but that means you will be looking at every single row in your table, and then checking if that row has a date that matches your parameters. This is really expensive, especially if you are in the business of storing events by date in the first place (i.e. you have a lot of rows.)

You may be tempted to put all the data in a single partition to solve the problem, and you absolutely can, however your throughput will be painfully low, given that each partition only receives a fraction of the total set amount.

The best thing to do is determine more useful partitions to create to save the data:

• Do you really need to look at all the rows, or is it only the rows by a specific user?

• Would it be okay to first narrow down the list by Month, and do multiple queries (one for each month)? Or by Year?

• If you are doing time series analysis there are a couple of options, change the partition key to something computated on PUT to make the query easier, or use another aws product like kinesis which lends itself to append-only logging.

1) This works without imports in Python 2:

>>>
>>> 'Some text'.encode('base64')
'U29tZSB0ZXh0\n'
>>>
>>> 'U29tZSB0ZXh0\n'.decode('base64')
'Some text'
>>>
>>> 'U29tZSB0ZXh0'.decode('base64')
'Some text'
>>>

(although this doesn't work in Python3 )

2) In Python 3 you'd have to import base64 and do base64.b64decode('...') - will work in Python 2 too.

Try this:

Dim dataView As New DataView(table)
dataView.Sort = " AutoID DESC, Name DESC"
Dim dataTable AS DataTable = dataView.ToTable()

Try XmlSerialization

try this

[Serializable]
public class Task
{
    public string Name{get; set;}
    public string Location {get; set;}
    public string Arguments {get; set;}
    public DateTime RunWhen {get; set;}
}

public void WriteXMl(Task task)
{
    XmlSerializer serializer;
    serializer = new XmlSerializer(typeof(Task));

    MemoryStream stream = new MemoryStream();

    StreamWriter writer = new StreamWriter(stream, Encoding.Unicode);
    serializer.Serialize(writer, task);

    int count = (int)stream.Length;

     byte[] arr = new byte[count];
     stream.Seek(0, SeekOrigin.Begin);

     stream.Read(arr, 0, count);

     using (BinaryWriter binWriter=new BinaryWriter(File.Open(@"C:\Temp\Task.xml", FileMode.Create)))
     {
         binWriter.Write(arr);
     }
 }

 public Task GetTask()
 {
     StreamReader stream = new StreamReader(@"C:\Temp\Task.xml", Encoding.Unicode);
     return (Task)serializer.Deserialize(stream);
 }

You can use within <td> tag css : display:inline-block

Like: <td style="display:inline-block">

Here are three different ways to do it:

Here's a working Demo in Fiddle Of All Three

Validation:

You can use native bootstrap validation states (No Custom CSS!):

<div class="form-group has-feedback">
    <label class="control-label" for="inputSuccess2">Name</label>
    <input type="text" class="form-control" id="inputSuccess2"/>
    <span class="glyphicon glyphicon-search form-control-feedback"></span>
</div>

For a full discussion, see my answer to Add a Bootstrap Glyphicon to Input Box

Input Group:

You can use the .input-group class like this:

<div class="input-group">
    <input type="text" class="form-control"/>
    <span class="input-group-addon">
        <i class="fa fa-search"></i>
    </span>
</div>

For a full discussion, see my answer to adding Twitter Bootstrap icon to Input box

Unstyled Input Group:

You can still use .input-group for positioning but just override the default styling to make the two elements appear separate.

Use a normal input group but add the class input-group-unstyled:

<div class="input-group input-group-unstyled">
    <input type="text" class="form-control" />
    <span class="input-group-addon">
        <i class="fa fa-search"></i>
    </span>
</div>

Then change the styling with the following css:

.input-group.input-group-unstyled input.form-control {
    -webkit-border-radius: 4px;
       -moz-border-radius: 4px;
            border-radius: 4px;
}
.input-group-unstyled .input-group-addon {
    border-radius: 4px;
    border: 0px;
    background-color: transparent;
}

Also, these solutions work for any input size

Here's a short way to convert it to hex:

public String toHex(String arg) {
    return String.format("%040x", new BigInteger(1, arg.getBytes(/*YOUR_CHARSET?*/)));
}

The following simple test:

C++ Array vs Vector performance test explanation

contradicts the conclusions from "Comparison of assembly code generated for basic indexing, dereferencing, and increment operations on vectors and arrays/pointers."

There must be a difference between the arrays and vectors. The test says so... just try it, the code is there...

Basic difference is that Google App Engine (GAE) is a Platform as a Service (PaaS) whereas Google Compute Engine (GCE) is an Infrastructure as a Service (IaaS).

To run your application in GAE you just need to write your code and deploy it into GAE, no other headache. Since GAE is fully scalable, it will automatically acquire more instances in case the traffic goes higher and decrease the instances when traffic decreases. You will be charged for the resources you really use, I mean, you will be billed for the Instance-Hours, Transferred Data, Storage etc your app really used. But the restriction is, you can create your application in only Python, PHP, Java, NodeJS, .NET, Ruby and **Go.

On the other hand, GCE provides you full infrastructure in the form of Virtual Machine. You have complete control over those VMs' environment and runtime as you can write or install any program there. Actually GCE is the way to use Google Data Centers virtually. In GCE you have to manually configure your infrastructure to handle scalability by using Load Balancer.

Both GAE and GCE are part of Google Cloud Platform.

Update: In March 2014 Google announced a new service under App Engine named Managed Virtual Machine. Managed VMs offers app engine applications a bit more flexibility over app platform, CPU and memory options. Like GCE you can create a custom runtime environment in these VMs for app engine application. Actually Managed VMs of App Engine blurs the frontier between IAAS and PAAS to some extent.

Short answer? Sometimes.

Technically every abstraction has a cost and a programming language is an abstraction for how the CPU works. C however is very close. Years ago I remember laughing out loud when I logged onto my UNIX account and got the following fortune message (when such things were popular):

The C Programming Language -- A language which combines the flexibility of assembly language with the power of assembly language.

It's funny because it's true: C is like portable assembly language.

It's worth noting that assembly language just runs however you write it. There is however a compiler in between C and the assembly language it generates and that is extremely important because how fast your C code is has an awful lot to do with how good your compiler is.

When gcc came on the scene one of the things that made it so popular was that it was often so much better than the C compilers that shipped with many commercial UNIX flavours. Not only was it ANSI C (none of this K&R C rubbish), was more robust and typically produced better (faster) code. Not always but often.

I tell you all this because there is no blanket rule about the speed of C and assembler because there is no objective standard for C.

Likewise, assembler varies a lot depending on what processor you're running, your system spec, what instruction set you're using and so on. Historically there have been two CPU architecture families: CISC and RISC. The biggest player in CISC was and still is the Intel x86 architecture (and instruction set). RISC dominated the UNIX world (MIPS6000, Alpha, Sparc and so on). CISC won the battle for the hearts and minds.

Anyway, the popular wisdom when I was a younger developer was that hand-written x86 could often be much faster than C because the way the architecture worked, it had a complexity that benefitted from a human doing it. RISC on the other hand seemed designed for compilers so noone (I knew) wrote say Sparc assembler. I'm sure such people existed but no doubt they've both gone insane and been institutionalized by now.

Instruction sets are an important point even in the same family of processors. Certain Intel processors have extensions like SSE through SSE4. AMD had their own SIMD instructions. The benefit of a programming language like C was someone could write their library so it was optimized for whichever processor you were running on. That was hard work in assembler.

There are still optimizations you can make in assembler that no compiler could make and a well written assembler algoirthm will be as fast or faster than it's C equivalent. The bigger question is: is it worth it?

Ultimately though assembler was a product of its time and was more popular at a time when CPU cycles were expensive. Nowadays a CPU that costs $5-10 to manufacture (Intel Atom) can do pretty much anything anyone could want. The only real reason to write assembler these days is for low level things like some parts of an operating system (even so the vast majority of the Linux kernel is written in C), device drivers, possibly embedded devices (although C tends to dominate there too) and so on. Or just for kicks (which is somewhat masochistic).

Declare separate functions in the <head> section and invoke those in your onClick method. If you have lots you could use a naming scheme that numbers them, or pass an integer in in your onClicks and have a big fat switch statement in the function.

On https://help.directadmin.com/item.php?id=589 they write:

If you need a quick way to reset your public_html data to 755 for directories and 644 for files, then you can use something like this:

cd /home/user/domains/domain.com/public_html
find . -type d -exec chmod 0755 {} \;
find . -type f -exec chmod 0644 {} \;

I tested and ... it works!

How about

wc -l file.txt | cut -d' ' -f1

i.e. pipe the output of wc into cut (where delimiters are spaces and pick just the first field)

Swift 3.0:

Int("5")

or

let stringToConvert = "5"
Int(stringToConvert)

It's even easier with SwiftUI:

var body: some View {     
    Text("Hello World")
    .onReceive(NotificationCenter.default.publisher(for: UIApplication.willResignActiveNotification)) { _ in

Your answer is Wi-Fi direct which is made available with ICS. Here is a link for explanation in Android doc

You can take a reference on the control on the ItemCreated event, and then use it later.

Update for 2020 - BinaryPrimitives should now be preferred over BitConverter. It provides endian-specific APIs, and is less allocatey.

byte[] bytes = BitConverter.GetBytes(i);

although note also that you might want to check BitConverter.IsLittleEndian to see which way around that is going to appear!

Note that if you are doing this repeatedly you might want to avoid all those short-lived array allocations by writing it yourself via either shift operations (>> / <<), or by using unsafe code. Shift operations also have the advantage that they aren't affected by your platform's endianness; you always get the bytes in the order you expect them.

What you really want to do is bind the event handler for the capture phase of the event. However, that isn't supported in IE as far as I know, so that might not be all that useful.

You can do this without a JOIN:

SELECT *
FROM (SELECT *,COUNT(*) OVER(PARTITION BY phone_number) as Phone_CT
      FROM YourTable
      )sub
WHERE Phone_CT > 1
ORDER BY phone_number, employee_ids

Demo: SQL Fiddle

This solution will work regardless of the number of char variables you have:

char c1 = 'z';
char c2 = 'w';
std::string s1{c1};
std::string s12{c1, c2};

It's simply “No such directory entry”. Since directory entries can be directories or files (or symlinks, or sockets, or pipes, or devices), the name ENOFILE would have been too narrow in its meaning.

a negative index will count from the end of the list, so:

num_list[-9:]

Here is an example of iterating over a pd.DataFrame grouped by the column atable. For this sample, "create" statements for an SQL database are generated within the for loop:

import pandas as pd

df1 = pd.DataFrame({
    'atable':     ['Users', 'Users', 'Domains', 'Domains', 'Locks'],
    'column':     ['col_1', 'col_2', 'col_a', 'col_b', 'col'],
    'column_type':['varchar', 'varchar', 'int', 'varchar', 'varchar'],
    'is_null':    ['No', 'No', 'Yes', 'No', 'Yes'],
})

df1_grouped = df1.groupby('atable')

# iterate over each group
for group_name, df_group in df1_grouped:
    print('\nCREATE TABLE {}('.format(group_name))

    for row_index, row in df_group.iterrows():
        col = row['column']
        column_type = row['column_type']
        is_null = 'NOT NULL' if row['is_null'] == 'NO' else ''
        print('\t{} {} {},'.format(col, column_type, is_null))

    print(");")

You should put the script as argument for a *NIX shell you run, equivalent to the *NIXish

sh myscriptfile

If you don't have a modifiable lvalue of an iterator, or it is desired to get a copy of a given iterator (leaving the original one unchanged), then C++11 comes with new helper functions - std::next / std::prev:

std::next(iter, 2);          // returns a copy of iter incremented by 2
std::next(std::begin(v), 2); // returns a copy of begin(v) incremented by 2
std::prev(iter, 2);          // returns a copy of iter decremented by 2

As I posted in the comment you don't need to use both setTimeout() and setInterval(), moreover you have a syntax error too (the one extra }). Correct your code like this:

(edited to add two functions to force the next/previous image to be shown)

<!DOCTYPE html>

<html>
   <head>
      <title>change picture</title>
      <script type = "text/javascript">
          function displayNextImage() {
              x = (x === images.length - 1) ? 0 : x + 1;
              document.getElementById("img").src = images[x];
          }

          function displayPreviousImage() {
              x = (x <= 0) ? images.length - 1 : x - 1;
              document.getElementById("img").src = images[x];
          }

          function startTimer() {
              setInterval(displayNextImage, 3000);
          }

          var images = [], x = -1;
          images[0] = "image1.jpg";
          images[1] = "image2.jpg";
          images[2] = "image3.jpg";
      </script>
   </head>

   <body onload = "startTimer()">
       <img id="img" src="startpicture.jpg"/>
       <button type="button" onclick="displayPreviousImage()">Previous</button>
       <button type="button" onclick="displayNextImage()">Next</button>
   </body>
</html>

To replace a specific position:

s = s[:pos] + s[(pos+1):]

To replace a specific character:

s = s.replace('M','')

Use the CSS display values of table and table-cell:

HTML

<html>
<body>

  <div class="valign bottom">
    <div>

      <div>my bottom aligned div 1</div>
      <div>my bottom aligned div 2</div>
      <div>my bottom aligned div 3</div>

    </div>
  </div>

</body>
</html>

CSS

html,body {
    width: 100%;
    height: 100%;
}
.valign {
    display: table;
    width: 100%;
    height: 100%;
}
.valign > div {
    display: table-cell;
    width: 100%;
    height: 100%;
}
.valign.bottom > div {
    vertical-align: bottom;
}

I've created a JSBin demo here: http://jsbin.com/INOnAkuF/2/edit

The demo also has an example how to vertically center align using the same technique.

NPM shrinkwrap offers a nice solution to this problem. It allows us to override that version of a particular dependency of a particular sub-module.

Essentially, when you run npm install, npm will first look in your root directory to see whether a npm-shrinkwrap.json file exists. If it does, it will use this first to determine package dependencies, and then falling back to the normal process of working through the package.json files.

To create an npm-shrinkwrap.json, all you need to do is

 npm shrinkwrap --dev

code:

{
  "dependencies": {
    "grunt-contrib-connect": {
      "version": "0.3.0",
      "from": "[email protected]",
      "dependencies": {
        "connect": {
          "version": "2.8.1",
          "from": "connect@~2.7.3"
        }
      }
    }
  }
}

With a recent nightly, you can do this:

let my_int = from_str::<int>(&*my_string);

What's happening here is that String can now be dereferenced into a str. However, the function wants an &str, so we have to borrow again. For reference, I believe this particular pattern (&*) is called "cross-borrowing".

If g++ still gives error Try using:

g++ file.c -lstdc++

Look at this post: What is __gxx_personality_v0 for?

Make sure -lstdc++ is at the end of the command. If you place it at the beginning (i.e. before file.c), you still can get this same error.

LayoutInflater.from(context).inflate(R.layout.row_payment_gateway_item, null);

You can't do that, because GetFiles only accepts a single search pattern. Instead, you can call GetFiles with no pattern, and filter the results in code:

string[] extensions = new[] { ".jpg", ".tiff", ".bmp" };

FileInfo[] files =
    dinfo.GetFiles()
         .Where(f => extensions.Contains(f.Extension.ToLower()))
         .ToArray();

If you're working with .NET 4, you can use the EnumerateFiles method to avoid loading all FileInfo objects in memory at once:

string[] extensions = new[] { ".jpg", ".tiff", ".bmp" };

FileInfo[] files =
    dinfo.EnumerateFiles()
         .Where(f => extensions.Contains(f.Extension.ToLower()))
         .ToArray();

For windows8 right click my pc properties then click environment variables user variable or System variables >> new >> put variable name and path : like this C:\Program Files\nodejs Then ok now open cmd and type npm it will work

My experience is that Ionic Pro (https://ionicframework.com/pro) can do the most of the Development and Publish job but you still need Mac or Mac in cloud at these steps:

• create .p12 Certification file
• upload the .ipa file to the App Store

After you created your Certification file, You can upload it to Ionic Pro. You can build .ipa files with proper credentials in cloud. But unfortunately I didn't found another way to upload the .ipa file to App Store, only with Application Loader from Mac.

So I decided to use a pay-as-you-go Mac in cloud account (you pay only for minutes you are logged in) since the time I spend on Mac is very limited (few minutes per App publication).

In modern versions of IE (IE10 and above), scrollbars can be hidden using the -ms-overflow-style property.

html {
     -ms-overflow-style: none;
}

In Chrome, scrollbars can be styled:

::-webkit-scrollbar {
    display: none;
}

This is very useful if you want to use the 'default' body scrolling in a web application, which is considerably faster than overflow-y: scroll.

Make sure you are using the SSH URL for the GitHub repository rather than the HTTPS URL. It will ask for username and password when you are using HTTPS and not SSH. You can check the file .git/config or run git config -e or git remote show origin to verify the URL and change it if needed.

Here we go.. We will need two classes. I am posting a code which changes mobile audio profile after each 5 seconds (5000 mili seconds) ...

Our 1st Class

public class ChangeProfileActivityMain extends Activity {

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        // TODO Auto-generated method stub
        super.onCreate(savedInstanceState);

        Timer timer = new Timer();
        TimerTask updateProfile = new CustomTimerTask(ChangeProfileActivityMain.this);
        timer.scheduleAtFixedRate(updateProfile, 0, 5000);
    }

}

Our 2nd Class

public class CustomTimerTask extends TimerTask {

    private AudioManager audioManager;
    private Context context;
    private Handler mHandler = new Handler();

    // Write Custom Constructor to pass Context
    public CustomTimerTask(Context con) {
        this.context = con;
    }

    @Override
    public void run() {
        // TODO Auto-generated method stub

        // your code starts here.
        // I have used Thread and Handler as we can not show Toast without starting new thread when we are inside a thread.
        // As TimePicker has run() thread running., So We must show Toast through Handler.post in a new Thread. Thats how it works in Android..
        new Thread(new Runnable() {
            @Override
            public void run() {
                audioManager = (AudioManager) context.getApplicationContext().getSystemService(Context.AUDIO_SERVICE);
                mHandler.post(new Runnable() {
                    @Override
                    public void run() {
                        if(audioManager.getRingerMode() == AudioManager.RINGER_MODE_SILENT) {
                            audioManager.setRingerMode(AudioManager.RINGER_MODE_NORMAL);
                            Toast.makeText(context, "Ringer Mode set to Normal", Toast.LENGTH_SHORT).show();
                        } else {
                            audioManager.setRingerMode(AudioManager.RINGER_MODE_SILENT);
                            Toast.makeText(context, "Ringer Mode set to Silent", Toast.LENGTH_SHORT).show();
                        }
                    }
                });
            }
        }).start();

    }

}

Move the -h and specify that mydir is a directory

attrib /S /D /L -H mydir\*.*

Count the number of digits w/o convert integer to a string:

x=123
x=abs(x)
i = 0
while x >= 10**i:
    i +=1
# i is the number of digits

This will check if particular email address exist in the table:

if (isset(User::where('email', Input::get('email'))->value('email')))
{
    // Input::get('email') exist in the table 
}

This is a late answer, but Joshua Bloch committed his Base64 class (when he was working for Sun, ahem, Oracle) under the java.util.prefs package. This class existed since JDK 1.4.

E.g.

String currentString = "Hello World";
String base64String = java.util.prefs.Base64.byteArrayToBase64(currentString.getBytes("UTF-8"));

== has higher precedence than &. You might want to wrap your operations in () to specify how you want your operands to bind to the operators.

((a[0] & 1) == 0)

Similarly for all parts of the if condition.

I was finally able to get this to work for my needs.

The old voted up code does not run on windows 10 system (at least not mine). The referenced MS library link below provides current examples on how to make this work. My example uses them with late bindings.

https://docs.microsoft.com/en-us/windows/win32/shell/folder-getdetailsof.

The attribute codes were different on my computer and like someone mentioned above most return blank values even if they are not. I used a for loop to cycle through all of them and found out that Title and Subject can still be accessed which is more then enough for my purposes.

Private Sub MySubNamek()
Dim objShell  As Object 'Shell
Dim objFolder As Object 'Folder

Set objShell = CreateObject("Shell.Application")
Set objFolder = objShell.NameSpace("E:\MyFolder")

If (Not objFolder Is Nothing) Then
Dim objFolderItem As Object 'FolderItem
Set objFolderItem = objFolder.ParseName("Myfilename.txt")
        For i = 0 To 288
           szItem = objFolder.GetDetailsOf(objFolderItem, i)
           Debug.Print i & " - " & szItem
       Next
Set objFolderItem = Nothing
End If

Set objFolder = Nothing
Set objShell = Nothing
End Sub

Initially starting with a pyspark dataframes - I got type conversion errors (when converting to pandas df's and then appending to csv) given the schema/column types in my pyspark dataframes

Solved the problem by forcing all columns in each df to be of type string and then appending this to csv as follows:

with open('testAppend.csv', 'a') as f:
    df2.toPandas().astype(str).to_csv(f, header=False)

You could use a regular expression like this

If Regex.IsMatch(number, "^[0-9 ]+$") Then

...

End If
