I have included this code in my /etc/apache2/apache2.conf

you can make any layout scrollable. Just under <?xml version="1.0" encoding="utf-8"?> add these lines:

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

and at the end add </ScrollView>

example of a non-scrollable activity:

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/activity_main"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:orientation="vertical"
    android:paddingBottom="@dimen/activity_vertical_margin"
    android:paddingLeft="@dimen/activity_horizontal_margin"
    android:paddingRight="@dimen/activity_horizontal_margin"
    android:paddingTop="@dimen/activity_vertical_margin"
    android:verticalScrollbarPosition="right"
    tools:context="p32929.demo.MainActivity">


    <TextView
        android:text="TextView"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="102dp"
        android:id="@+id/textView"
        android:textSize="30sp" />
</RelativeLayout>

After making it scrollable, it becomes like this:

<?xml version="1.0" encoding="utf-8"?>

<ScrollView xmlns:android="http://schemas.android.com/apk/res/android"
    android:layout_width="match_parent"
    android:layout_height="match_parent">

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
        xmlns:tools="http://schemas.android.com/tools"
        android:id="@+id/activity_main"
        android:layout_width="match_parent"
        android:layout_height="match_parent"
        android:orientation="vertical"
        android:paddingBottom="@dimen/activity_vertical_margin"
        android:paddingLeft="@dimen/activity_horizontal_margin"
        android:paddingRight="@dimen/activity_horizontal_margin"
        android:paddingTop="@dimen/activity_vertical_margin"
        android:verticalScrollbarPosition="right"
        tools:context="p32929.demo.MainActivity">


        <TextView
            android:id="@+id/textView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            android:layout_alignParentTop="true"
            android:layout_centerHorizontal="true"
            android:layout_marginTop="102dp"
            android:text="TextView"
            android:textSize="30sp" />
    </RelativeLayout>
</ScrollView>

Short answer: for both PUT and DELETE, you should send either 200 (OK) or 204 (No Content).

Long answer: here's a complete decision diagram (click to magnify).

There are GUI tools for debugging stored procedures / functions and scripts in MySQL. A decent tool that dbForge Studio for MySQL, has rich functionality and stability.

Another easiest solution is to use Key.RETUEN

Click here for solution in detail

driver.findElement(By.name("q")).sendKeys("Selenium Tutorial", Key.RETURN);

If you have installed Apache with OpenSSL navigate to bin directory. In my case D:\apache\bin.

*These commands also work if you have stand alone installation of openssl.

Run these commands:

openssl req -config d:\apache\conf\openssl.cnf -new -out d:\apache\conf\server.csr -keyout d:\apache\conf\server.pem
openssl rsa -in d:\apache\conf\server.pem -out d:\apache\conf\server.key
openssl x509 -in d:\apache\conf\server.csr -out d:\apache\conf\server.crt -req -signkey d:\apache\conf\server.key -days 365

*This will create self-signed certificate that you can use for development purposes

Again if you have Apache installed in the httpd.conf stick these:

  <IfModule ssl_module>
    SSLEngine on
    SSLCertificateFile "D:/apache/conf/server.crt"
    SSLCertificateKeyFile "D:/apache/conf/server.key"
  </IfModule>

I made myself a custom jquery function:

Html

<tr data-href="site.com/whatever">

jQuery

$('tr[data-href]').on("click", function() {
    document.location = $(this).data('href');
});

Easy and perfect for me. Hopefully it helps you.

(I know OP want CSS and HTML only, but consider jQuery)

Edit

Agreed with Matt Kantor using data attr. Edited answer above

sort -nk2 file.txt

Accordingly you can change column number.

c# 7.0 lets you do this:

  var tupleList = new List<(int, string)>
  {
      (1, "cow"),
      (5, "chickens"),
      (1, "airplane")
  };

If you don't need a List, but just an array, you can do:

  var tupleList = new(int, string)[]
  {
      (1, "cow"),
      (5, "chickens"),
      (1, "airplane")
  };

And if you don't like "Item1" and "Item2", you can do:

  var tupleList = new List<(int Index, string Name)>
  {
      (1, "cow"),
      (5, "chickens"),
      (1, "airplane")
  };

or for an array:

  var tupleList = new (int Index, string Name)[]
  {
      (1, "cow"),
      (5, "chickens"),
      (1, "airplane")
  };

which lets you do: tupleList[0].Index and tupleList[0].Name

Framework 4.6.2 and below

You must install System.ValueTuple from the Nuget Package Manager.

Framework 4.7 and above

It is built into the framework. Do not install System.ValueTuple. In fact, remove it and delete it from the bin directory.

note: In real life, I wouldn't be able to choose between cow, chickens or airplane. I would be really torn.

class Program
{
    Variable va = new Variable();
    static void Main(string[] args)
    {
        va.name = "Stackoverflow";
    }
}

Although that did work, it took out the entire background colour as well. I was looking for a way to do just the border and just replace that XML layout code with this one and I was good to go!

<shape xmlns:android="http://schemas.android.com/apk/res/android">
    <stroke android:width="4dp" android:color="#FF00FF00" />
    <padding android:left="7dp" android:top="7dp"
            android:right="7dp" android:bottom="7dp" />
    <corners android:radius="4dp" />
</shape> 

Without more detail of what you are trying to accomplish, we are kinda guessing. But you might be able to get away with using object notation to do something like this...

var myFuncs = {
  firstFunc: function(string) {
    // do something
  },

  secondFunc: function(string) {
    // do something
  },

  thirdFunc: function(string) {
    // do something
  }
}

and to call one of them...

myFuncs.firstFunc('a string')

My answer is "neither one".

I believe the most "Pythonic" way to do things is to NOT check beforehand if the key is in a dictionary and instead just write code that assumes it's there and catch any KeyErrors that get raised because it wasn't.

This is usually done with enclosing the code in a try...except clause and is a well-known idiom usually expressed as "It's easier to ask forgiveness than permission" or with the acronym EAFP, which basically means it is better to try something and catch the errors instead for making sure everything's OK before doing anything. Why validate what doesn't need to be validated when you can handle exceptions gracefully instead of trying to avoid them? Because it's often more readable and the code tends to be faster if the probability is low that the key won't be there (or whatever preconditions there may be).

Of course, this isn't appropriate in all situations and not everyone agrees with the philosophy, so you'll need to decide for yourself on a case-by-case basis. Not surprisingly the opposite of this is called LBYL for "Look Before You Leap".

As a trivial example consider:

if 'name' in dct:
    value = dct['name'] * 3
else:
    logerror('"%s" not found in dictionary, using default' % name)
    value = 42

vs

try:
    value = dct['name'] * 3
except KeyError:
    logerror('"%s" not found in dictionary, using default' % name)
    value = 42

Although in the case it's almost exactly the same amount of code, the second doesn't spend time checking first and is probably slightly faster because of it (try...except block isn't totally free though, so it probably doesn't make that much difference here).

Generally speaking, testing in advance can often be much more involved and the savings gain from not doing it can be significant. That said, if 'name' in dict: is better for the reasons stated in the other answers.

If you're interested in the topic, this message titled "EAFP vs LBYL (was Re: A little disappointed so far)" from the Python mailing list archive probably explains the difference between the two approached better than I have here. There's also a good discussion about the two approaches in the book Python in a Nutshell, 2nd Ed by Alex Martelli in chapter 6 on Exceptions titled Error-Checking Strategies. (I see there's now a newer 3rd edition, publish in 2017, which covers both Python 2.7 and 3.x).

When the accepted answer doesn't work (for example when dealing with Paint) you can use:

float spTextSize = 12;
float textSize = spTextSize * getResources().getDisplayMetrics().scaledDensity;
textPaint.setTextSize(textSize);

I get the same issue and i solved it by replacing :

implementation 'com.google.firebase:firebase-core:16.0.1'

to

implementation 'com.google.firebase:firebase-core:15.0.2'

and everything solved and worked well.

Quick example:

final class Singleton
{
    private static $instance = null;

    private function __construct(){}

    private function __clone(){}

    private function __wakeup(){}

    public static function get_instance()
    {
        if ( static::$instance === null ) {
            static::$instance = new static();
        }
        return static::$instance;
    }
}

Hope help.

Hope this coding will helps you :)

plot(x,y,xaxt = 'n')

axis(side=1,at=c(1,20,30,50),labels=c("1975","1980","1985","1990"))

Here is a code that works for me, which is a part from the website above combined with my early trials: http://www.codeproject.com/KB/system/DriveDetector.aspx

This basically makes your form listen to windows messages, filters for usb drives and (cd-dvds), grabs the lparam structure of the message and extracts the drive letter.

protected override void WndProc(ref Message m)
    {

        if (m.Msg == WM_DEVICECHANGE)
        {
            DEV_BROADCAST_VOLUME vol = (DEV_BROADCAST_VOLUME)Marshal.PtrToStructure(m.LParam, typeof(DEV_BROADCAST_VOLUME));
            if ((m.WParam.ToInt32() == DBT_DEVICEARRIVAL) &&  (vol.dbcv_devicetype == DBT_DEVTYPVOLUME) )
            {
                MessageBox.Show(DriveMaskToLetter(vol.dbcv_unitmask).ToString());
            }
            if ((m.WParam.ToInt32() == DBT_DEVICEREMOVALCOMPLETE) && (vol.dbcv_devicetype == DBT_DEVTYPVOLUME))
            {
                MessageBox.Show("usb out");
            }
        }
        base.WndProc(ref m);
    }

    [StructLayout(LayoutKind.Sequential)] //Same layout in mem
    public struct DEV_BROADCAST_VOLUME
    {
        public int dbcv_size;
        public int dbcv_devicetype;
        public int dbcv_reserved;
        public int dbcv_unitmask;
    }

    private static char DriveMaskToLetter(int mask)
    {
        char letter;
        string drives = "ABCDEFGHIJKLMNOPQRSTUVWXYZ"; //1 = A, 2 = B, 3 = C
        int cnt = 0;
        int pom = mask / 2;
        while (pom != 0)    // while there is any bit set in the mask shift it right        
        {        
            pom = pom / 2;
            cnt++;
        }
        if (cnt < drives.Length)
            letter = drives[cnt];
        else
            letter = '?';
        return letter;
    }

Do not forget to add this:

using System.Runtime.InteropServices;

and the following constants:

    const int WM_DEVICECHANGE = 0x0219; //see msdn site
    const int DBT_DEVICEARRIVAL = 0x8000;
    const int DBT_DEVICEREMOVALCOMPLETE = 0x8004;
    const int DBT_DEVTYPVOLUME = 0x00000002;  

I have seen some solutions here worth noting, as Omer Eldan posted. but here follows. ASP C#

using System.Data;
using System.Web.UI.HtmlControls;

public static Table DataTableToHTMLTable(DataTable dt, bool includeHeaders)
{
    Table tbl = new Table();
    TableRow tr = null;
    TableCell cell = null;

    int rows = dt.Rows.Count;
    int cols = dt.Columns.Count;

    if (includeHeaders)
    {
        TableHeaderRow htr = new TableHeaderRow();
        TableHeaderCell hcell = null;
        for (int i = 0; i < cols; i++)
        {
            hcell = new TableHeaderCell();
            hcell.Text = dt.Columns[i].ColumnName.ToString();
            htr.Cells.Add(hcell);
        }
        tbl.Rows.Add(htr);
    }

    for (int j = 0; j < rows; j++)
    {
        tr = new TableRow();
        for (int k = 0; k < cols; k++)
        {
            cell = new TableCell();
            cell.Text = dt.Rows[j][k].ToString();
            tr.Cells.Add(cell);
        }
        tbl.Rows.Add(tr);
    }
    return tbl;
}

why this solution? Because you can easily just add this to a panel ie:

panel.Controls.Add(DataTableToHTMLTable(dtExample,true));

Second question , why do you have one column datatables and not just array's? Are you sure that these DataTables are uniform, because if the data is jagged then it's no use. If You really have to join these DataTables, there is many examples of Linq operations, or just use (beware though of same name columns as this will conflict in both linq operations and this solution if not handled):

public DataTable joinUniformTable(DataTable dt1, DataTable dt2)
{
    int dt2ColsCount = dt2.Columns.Count;
    int dt1lRowsCount = dt1.Rows.Count;

    DataColumn column;
    for (int i = 0; i < dt2ColsCount; i++)
    {
        column = new DataColumn();
        string colName = dt2.Columns[i].ColumnName;
        System.Type colType = dt2.Columns[i].DataType;
        column.ColumnName = colName;
        column.DataType = colType;
        dt1.Columns.Add(column);

        for (int j = 0; j < dt1lRowsCount; j++)
        {
            dt1.Rows[j][colName] = dt2.Rows[j][colName];
        }
    }
    return dt1;
}

and your solution would look something like:

panel.Controls.Add(DataTableToHTMLTable(joinUniformTable(joinUniformTable(LivDT,BathDT),BedDT),true));

interpret the rest, and have fun.

I'd like to add to the other answers this pretty new solution:

If you don't want the element to become inline-block, you can do this:

.parent{
  width: min-content;
}

The support is increasing fast, so when edge decides to implement it, it will be really great: http://caniuse.com/#search=intrinsic

An O(1) sollution might be to just guess: The smallest number in your array will often be 0. 0 crops up everywhere. Given that you are only looking at unsigned numbers. But even then: 0 is good enough. Also, looking through all elements for the smallest number is a real pain. Why not just use 0? It could actually be the correct result!

If the interviewer/your teacher doesn't like that answer, try 1, 2 or 3. They also end up being in most homework/interview-scenario numeric arrays...

On a more serious side: How often will you need to perform this operation on the array? Because the sollutions above are all O(n). If you want to do that m times to a list you will be adding new elements to all the time, why not pay some time up front and create a heap? Then finding the smallest element can really be done in O(1), without resulting to cheating.

As its name is "numbers" it is clear it is a list of number... So an array of number... no need of the attribute type... Although I like the principle of specifying the type of field in a type attribute...

If you want to fully automate the process (i.e. you want to increment the version number without having to know what the current version number is), you can do this:

mvn build-helper:parse-version versions:set -DnewVersion=\${parsedVersion.majorVersion}.\${parsedVersion.minorVersion}.\${parsedVersion.nextIncrementalVersion} versions:commit

Jenv on Mac Sierra:

if not working after install, do this bug fix to add java executable to path

export PATH="$HOME/.jenv/shims:$PATH"

even though eval "$(jenv init -)" could do this job. The reason is /bin folder is not there anymore as describe in it's homepage, but shim folder is used as /bin instead.

• Make sure ~/.jenv is there
• which java may print /Library/...
• jenv global 1.8
• jenv shell 1.8

Eventually, which java gives you:

/Users/xxxx/.jenv/shims/java

When you're going to work with such time series in Python, pandas is indispensable. And here's the good news: it comes with a historical data downloader for Yahoo: pandas.io.data.DataReader.

from pandas.io.data import DataReader
from datetime import datetime

ibm = DataReader('IBM',  'yahoo', datetime(2000, 1, 1), datetime(2012, 1, 1))
print(ibm['Adj Close'])

Here's an example from the pandas documentation.

Update for pandas >= 0.19:

The pandas.io.data module has been removed from pandas>=0.19 onwards. Instead, you should use the separate pandas-datareader package. Install with:

pip install pandas-datareader

And then you can do this in Python:

import pandas_datareader as pdr
from datetime import datetime

ibm = pdr.get_data_yahoo(symbols='IBM', start=datetime(2000, 1, 1), end=datetime(2012, 1, 1))
print(ibm['Adj Close'])

Downloading from Google Finance is also supported.

There's more in the documentation of pandas-datareader.

In case you are working with a column with string values, you can use THE VERY USEFUL function series.str.isnumeric() like:

a = pd.Series(['hi','hola','2.31','288','312','1312', '0,21', '0.23'])

What i do is to copy that column to new column, and do a str.replace('.','') and str.replace(',','') then i select the numeric values. and:

a = a.str.replace('.','')
a = a.str.replace(',','') 
a.str.isnumeric()

Out[15]: 0 False 1 False 2 True 3 True 4 True 5 True 6 True 7 True dtype: bool

Good luck all!

Why all the other answers use slideUp is just beyond me. As I'm using the fade and in classes to have the alert fade away when closed (or after timeout), I don't want it to "slide up" and conflict with that.

Besides the slideUp method didn't even work. The alert itself didn't show at all. Here's what worked perfectly for me:

$(document).ready(function() {
    // show the alert
    setTimeout(function() {
        $(".alert").alert('close');
    }, 2000);
});

If you've deleted your root user by mistake you can do one thing:

1. Stop MySQL service
2. Run mysqld_safe --skip-grant-tables &
3. Type mysql -u root -p and press enter.
4. Enter your password
5. At the mysql command line enter: use mysql;

Then execute this query:

insert into `user` (`Host`, `User`, `Password`, `Select_priv`, `Insert_priv`, `Update_priv`, `Delete_priv`, `Create_priv`, `Drop_priv`, `Reload_priv`, `Shutdown_priv`, `Process_priv`, `File_priv`, `Grant_priv`, `References_priv`, `Index_priv`, `Alter_priv`, `Show_db_priv`, `Super_priv`, `Create_tmp_table_priv`, `Lock_tables_priv`, `Execute_priv`, `Repl_slave_priv`, `Repl_client_priv`, `Create_view_priv`, `Show_view_priv`, `Create_routine_priv`, `Alter_routine_priv`, `Create_user_priv`, `ssl_type`, `ssl_cipher`, `x509_issuer`, `x509_subject`, `max_questions`, `max_updates`, `max_connections`, `max_user_connections`) 
values('localhost','root','','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','','','','','0','0','0','0');

then restart the mysqld

In case anyone else needs this answer, I tried it today using innodb_version 5.6.36-82.0 and 10.1.24-MariaDB and it works if you REMOVE THE BACKTICKS (no single quotes either, just remove them):

insert into user (Host, User, Password, Select_priv, Insert_priv, Update_priv, Delete_priv, Create_priv, Drop_priv, Reload_priv, Shutdown_priv, Process_priv, File_priv, Grant_priv, References_priv, Index_priv, Alter_priv, Show_db_priv, Super_priv, Create_tmp_table_priv, Lock_tables_priv, Execute_priv, Repl_slave_priv, Repl_client_priv, Create_view_priv, Show_view_priv, Create_routine_priv, Alter_routine_priv, Create_user_priv, ssl_type, ssl_cipher, x509_issuer, x509_subject, max_questions, max_updates, max_connections, max_user_connections) 
values('localhost','root','','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','Y','','','','','0','0','0','0');

Here's a Swift implementation. You can make an extension so that it will be usable by other views if you like.

extension UIView {
    func addBorderAndColor(color: UIColor, width: CGFloat, corner_radius: CGFloat = 0, clipsToBounds: Bool = false) {
        self.layer.borderWidth  = width
        self.layer.borderColor  = color.cgColor
        self.layer.cornerRadius = corner_radius
        self.clipsToBounds      = clipsToBounds
    }
}

Call this like: email.addBorderAndColor(color: UIColor.white, width: 0.5, corner_radius: 5, clipsToBounds: true).

or you may try something like

"abc.def.ghi".substring(0,"abc.def.ghi".indexOf(c)-1);

.bashrc is not sourced when you log in using SSH. You need to source it in your .bash_profile like this:

if [ -f ~/.bashrc ]; then
  . ~/.bashrc
fi

your can try this :

SELECT columnName1, CAST(columnName2 AS  SIGNED ) FROM tableName 

Invert match using grep -v:

grep -v "unwanted word" file pattern

If you are using WebClient, it has a Proxy property you can use.

As other have mentioned, there are several ways to automate proxy setting detection/usage

Web.Config:

<system.net>
   <defaultProxy enabled="true" useDefaultCredentials="true">
     <proxy usesystemdefault="true" bypassonlocal="true" />
   </defaultProxy>
</system.net>

Use of the WebProxy class as described in this article.

You can also cofigure the proxy settings directly (config or code) and your app will then use those.

Web.Config:

<system.net>
  <defaultProxy>
    <proxy
      proxyaddress="http://[proxy address]:[proxy port]"
      bypassonlocal="false"
    />
  </defaultProxy>
</system.net>

Code:

HttpWebRequest request = (HttpWebRequest)WebRequest.Create("url");
WebProxy myproxy = new WebProxy("[proxy address]:[proxy port]", false);
request.Proxy = myproxy;
request.Method = "GET";
HttpWebResponse response = (HttpWebResponse) request.GetResponse();

Wow, ya'll are overthinking it. It's as simple as the following. Besides, many of those answers aren't understood by the RE2 dialect used by C and golang.

^$

Try this:

select * 
from xxx 
where dates >= '2012-10-26 00:00:00.000' and dates <= '2012-10-27 23:59:59.997'

Does an implicit conversion occur between Task<> and int?

Nope. This is just part of how async/await works.

Any method declared as async has to have a return type of:

• void (avoid if possible)
• Task (no result beyond notification of completion/failure)
• Task<T> (for a logical result of type T in an async manner)

The compiler does all the appropriate wrapping. The point is that you're asynchronously returning urlContents.Length - you can't make the method just return int, as the actual method will return when it hits the first await expression which hasn't already completed. So instead, it returns a Task<int> which will complete when the async method itself completes.

Note that await does the opposite - it unwraps a Task<T> to a T value, which is how this line works:

string urlContents = await getStringTask;

... but of course it unwraps it asynchronously, whereas just using Result would block until the task had completed. (await can unwrap other types which implement the awaitable pattern, but Task<T> is the one you're likely to use most often.)

This dual wrapping/unwrapping is what allows async to be so composable. For example, I could write another async method which calls yours and doubles the result:

public async Task<int> AccessTheWebAndDoubleAsync()
{
    var task = AccessTheWebAsync();
    int result = await task;
    return result * 2;
}

(Or simply return await AccessTheWebAsync() * 2; of course.)

In case you want to do some more custom styling. Here's all the default CSS for webkit rendering of the date components.

input[type="date"] {
     -webkit-align-items: center;
     display: -webkit-inline-flex;
     font-family: monospace;
     overflow: hidden;
     padding: 0;
     -webkit-padding-start: 1px;
}

input::-webkit-datetime-edit {
    -webkit-flex: 1;
    -webkit-user-modify: read-only !important;
    display: inline-block;
    min-width: 0;
    overflow: hidden;
}

input::-webkit-datetime-edit-fields-wrapper {
    -webkit-user-modify: read-only !important;
    display: inline-block;
    padding: 1px 0;
    white-space: pre;
}

If you have a very limited number of levels, you could try converting y into factor and change its levels.

> xy <- data.frame(x = c(1, 2, 4), y = c(1, 4, 5))
> xy$w <- as.factor(xy$y)
> levels(xy$w) <- c("good", "fair", "bad")
> xy
  x y    w
1 1 1 good
2 2 4 fair
3 4 5  bad

You don't say what shell you are using, but they generally don't support regular expressions that way, although there are common *nix CLI tools (grep, sed, etc) that do.

What shells like bash do support is globbing, which uses some similiar characters (eg, *) but is not the same thing.

Newer versions of bash do have a regular expression operator, =~:

for x in `ls`; do 
    if [[ $x =~ .+\..* ]]; then 
        echo $x; 
    fi; 
done

Any collection that you iterate over with foreach may not be modified during iteration.

So while you're running a foreach over rankings, you cannot modify its elements, add new ones or delete any.

try the following example. Image overlay with text on image. demo

    background: rgba(0, 0, 0, 0.7) none repeat scroll 0 0;
    opacity: 0.5;

One can try Java Operator Overloading. It has its own limitations, but it worth trying if you really want to use operator overloading.

Go to a Packages/User, create (or edit) a .sublime-settings file named after the Syntax where you want to add the extensions, Ini.sublime-settings in your case, then write there something like this:

{
    "extensions":["cfg"]
}

And then restart Sublime Text

They are not identical. Memcache is older but it has some limitations. I was using just fine in my application until I realized you can't store literal FALSE in cache. Value FALSE returned from the cache is the same as FALSE returned when a value is not found in the cache. There is no way to check which is which. Memcached has additional method (among others) Memcached::getResultCode that will tell you whether key was found.

Because of this limitation I switched to storing empty arrays instead of FALSE in cache. I am still using Memcache, but I just wanted to put this info out there for people who are deciding.

//xn=list of parent nodes......                
foreach (XmlNode xn in xnList)
{                                           
    foreach (XmlNode child in xn.ChildNodes) 
    {
        if (child.Name.Equals("name")) 
        {
            name = child.InnerText; 
        }
        if (child.Name.Equals("age"))
        {
            age = child.InnerText; 
        }
    }
}

You could throw the enum value and string into an STL map. Then you could use it like so.

   return myStringMap[Enum::Apple];

Plotly is missing in this list. I've linked the python binding page. It definitively has animated and interative 3D Charts. And since it is Open Source most of that is available offline. Of course it is working with Jupyter

For Fedora use:

yum install libstdc++44.i686

You can find out which versions are supported by running:

yum list all | grep libstdc | grep i686

var textToFind = 'Google';

var dd = document.getElementById('MyDropDown');
for (var i = 0; i < dd.options.length; i++) {
    if (dd.options[i].text === textToFind) {
        dd.selectedIndex = i;
        break;
    }
}

Try this:

preg_replace('/[^0-9]/', '', '604-619-5135');

preg_replace uses PCREs which generally start and end with a /.

Generic AlertDialogFragment with Builder Pattern

In my project, I already used AlertDialog.Builder already a lot before I found out that it's problematic. However, I did not want to change that much code anywhere in my app. Additionally, I actually am a fan of passing OnClickListeners as anonymous classes where they are needed (that is, when using setPositiveButton(), setNegativeButton() etc.) instead of having to implement thousands of callback methods to communicate between a dialog fragment and the holder fragment, which can, in my opinion, lead to very confusing and complex code. Especially, if you have multiple different dialogs in one fragment and then need to distinguish in the callback implementations between which dialog currently being shown.

Therefore, I combined different approaches to create a generic AlertDialogFragment helper class which can be used exactly like AlertDialog:

SOLUTION

(PLEASE NOTE that I am using Java 8 lambda expressions in my code, so you might have to change parts of the code if you are not using lambda expressions yet.)

USAGE

// showing a normal alert dialog with state loss on configuration changes (like device rotation)
new AlertDialog.Builder(getActivity())
        .setTitle("Are you sure? (1)")
        .setMessage("Do you really want to do this?")
        .setPositiveButton("Yes", (dialog, which) -> Toast.makeText(getContext(), "Yes clicked", Toast.LENGTH_SHORT).show())
        .setNegativeButton("Cancel", null)
        .show();

// showing a dialog fragment using the helper class with no state loss on configuration changes
new AlertDialogFragment.builder(getActivity())
        .setTitle("Are you sure? (2)")
        .setMessage("Do you really want to do this?")

        .setNegativeButton("Cancel", null)
        .show();

I am posting this here not only to share my solution, but also because I wanted to ask you people for your opinion: Is this approach legit or problematic to some extent?

I tried opening my Credential Manager but could not find any credentials in there that has any relation to my TFS account.

So what I did instead I logout of my hotmail account in Internet Explorer and then clear all my Internet Explorer cookies and stored password as detailed in this blog: Changing TFS credentials in Visual Studio 2012

After clearing out the cookies and password, restart IE and then relogin to your hotmail (or windows live account).

Then start Visual Studio and try to reconnect to TFS, you should be prompted for a credential now.

Note: A reader said that you do not have to clear out all IE cookies, just these 3 cookies, but I didn't test this.

cookie:@login.live.com/
cookie:@visualstudio.com/
cookie:@tfs.app.visualstudio.com/

The only way I found to work with hours, through an US format in source (mm-dd-yyyy HH-MM-SS PM/AM)...

df_dataSet$time <- as.POSIXct( df_dataSet$time , format = "%m/%d/%Y %I:%M:%S %p" , tz = "GMT")
class(df_dataSet$time)
df_dataSet <- df_dataSet[do.call(order, df_dataSet), ] 

For static declaration I think you could use:

T myarray[100] = {0};

For dynamic declaration I suggest the same way: memset

Check out the addressable gem - a popular replacement for Ruby's URI module that makes query parsing easy:

require "addressable/uri"
uri = Addressable::URI.parse("http://www.example.com/something?param1=value1&param2=value2&param3=value3")
uri.query_values['param1']
=> 'value1'

(It also apparently handles param encoding/decoding, unlike URI)

Its simple only one line code is needed for this. if String A = scanner.nextLine(); then you need to write this to display the string with this first letter capitalized.

System.out.println(A.substring(0, 1).toUpperCase() + A.substring(1));

And its done now.

Math.round(number*100.0)/100.0;

To the best of my memory, a physical address is an explicit, set in stone address in memory, while a logical address consists of a base pointer and offset.

The reason is as you have basically specified. It allows for not only the segmentation of programs and processes into threads and data, but also for the dynamic loading of such programs, and the allowance for at least pseudo-parallelism, without any actual interlacing of instructions in memory needing to take place.

Hint 1: read the description of linked lists at http://en.wikipedia.org/wiki/Linked_list

Hint 2: the Java implementation of LinkedList is a doubly linked list. Yours is a singly linked list. The algorithms don't directly apply.

Also:

... but creating [a linked list class] from scratch makes no sense whatsoever.

It depends on what the required outcome of the work is. If the goal is to produce code that meets certain functional / non-functional requirements, then you are right. If the real goal is for you to learn how to program / design APIs / implement non-trivial data structures, then the utility of the final product is almost entirely irrelevant.

And thus magically we have a linked list

What you actually have there is a open data type, that could be used to build a (sort of) list. But that is not what your teacher wants. And it certainly would not be considered to be a useful list abstraction. A useful abstraction would include:

• methods to do the things that programmers don't want to have to repeat over and over again, and

• an abstraction layer that stops programmers "breaking" the list; e.g. by accidentally creating a cycle, or accidentally stitching a sublist in two lists to create an inverted tree.

First you have to sort the dataframe by the count column max to min if it's not sorted that way already. In your post, it is in the right order already but I will sort it anyways:

dataframe.sort_index(by='count', ascending=[False])
    col     count
0   apple   5
1   sausage 2
2   banana  2
3   cheese  1 

Then you can output the col column to a list:

dataframe['col'].tolist()
['apple', 'sausage', 'banana', 'cheese']

If you know Array's length but you don't know its content, you can use

val length = 5
val temp = Array.ofDim[String](length)

If you want to have two dimensions array but you don't know its content, you can use

val row = 5
val column = 3
val temp = Array.ofDim[String](row, column)

Of course, you can change String to other type.

If you already know its content, you can use

val temp = Array("a", "b")

Here is a one-liner that can be extended with grep to filter by name.

kubectl get pods -o jsonpath="{.items[*].metadata.name}" | \
tr " " "\n" | \
xargs -i -P 0 kubectl delete pods {}

For me the filename involved was appended with a querystring, which this function didn't like.

$path = 'path/to/my/file.js?v=2'

Solution was to chop that off first:

$path = preg_replace('/\?v=[\d]+$/', '', $path);
$fileTime = filemtime($path);

The main use of -f is to force the removal of files that would not be removed using rm by itself (as a special case, it "removes" non-existent files, thus suppressing the error message).

You can also just redirect the error message using

$ rm file.txt 2> /dev/null

(or your operating system's equivalent). You can check the value of $? immediately after calling rm to see if a file was actually removed or not.

How about:

ACell.ListObject.DataBodyRange.Rows.Delete

That will keep your table structure and headings, but clear all the data and rows.

EDIT: I'm going to just modify a section of my answer from your previous post, as it does mostly what you want. This leaves just one row:

With loSource
   .Range.AutoFilter
   .DataBodyRange.Offset(1).Resize(.DataBodyRange.Rows.Count - 1, .DataBodyRange.Columns.Count).Rows.Delete
   .DataBodyRange.Rows(1).Specialcells(xlCellTypeConstants).ClearContents
End With

If you want to leave all the rows intact with their formulas and whatnot, just do:

With loSource
   .Range.AutoFilter
   .DataBodyRange.Specialcells(xlCellTypeConstants).ClearContents
End With

Which is close to what @Readify suggested, except it won't clear formulas.

Another streaming command I've had good results with is piping the ffmpeg output to vlc to create a stream. If you don't have these installed, you can add them:

sudo apt install vlc ffmpeg

In the example I use an mpeg transport stream (ts) over http, instead of rtsp. I've tried both, but the http ts stream seems to work glitch-free on my playback devices.

I'm using a video capture HDMI>USB device that sets itself up on the video4linux2 driver as input. Piping through vlc must be CPU-friendly, because my old dual-core Pentium CPU is able to do the real-time encoding with no dropped frames. I've also had audio-sync issues with some of the other methods, where this method always has perfect audio-sync.

You will have to adjust the command for your device or file. If you're using a file as input, you won't need all that v4l2 and alsa stuff. Here's the ffmpeg|vlc command:

ffmpeg -thread_queue_size 1024 -f video4linux2 -input_format mjpeg -i /dev/video0 -r 30 -f alsa -ac 1 -thread_queue_size 1024 -i hw:1,0 -acodec aac -vcodec libx264 -preset ultrafast -crf 18 -s hd720 -vf format=yuv420p -profile:v main -threads 0 -f mpegts -|vlc -I dummy - --sout='#std{access=http,mux=ts,dst=:8554}'

For example, lets say your server PC IP is 192.168.0.10, then the stream can be played by this command:

ffplay http://192.168.0.10:8554
#or
vlc http://192.168.0.10:8554

This error would happen when the number of guesses (so_far) is less than the length of the word. Did you miss an initialization for the variable so_far somewhere, that sets it to something like

so_far = " " * len(word)

?

Edit:

try something like

print "%d / %d" % (new, so_far)

before the line that throws the error, so you can see exactly what goes wrong. The only thing I can think of is that so_far is in a different scope, and you're not actually using the instance you think.

When you are inside an activity and need to go to a fragment use below

getFragmentManager().beginTransaction().replace(R.id.*TO_BE_REPLACED_LAYOUT_ID*, new tasks()).commit();

But when you are inside a fragment and need to go to a fragment then just add a getActivity(). before, so it would become

getActivity().getFragmentManager().beginTransaction().replace(R.id.*TO_BE_REPLACED_LAYOUT_ID*, new tasks()).commit();

as simple as that.

The *TO_BE_REPLACED_LAYOUT_ID* can be the entire page of activity or a part of it, just make sure to put an id to the layout to be replaced. It is general practice to put the replaceable layout in a FrameLayout .

In Rails 4.02+ according to the docs there is no method like update_all with 2 arguments. Instead one can use this code:

# Make sure no null value exist
MyModel.where(date_column: nil).update_all(date_column: Time.now)

# Change the column to not allow null
change_column :my_models, :date_column, :datetime, null: false

To generate a number between 10 to 20 inclusive, you can use java.util.Random

int myNumber = new Random().nextInt(11) + 10

Solution

color=$( convert filename.png -format "%[pixel:p{0,0}]" info:- )
convert filename.png -alpha off -bordercolor $color -border 1 \
    \( +clone -fuzz 30% -fill none -floodfill +0+0 $color \
       -alpha extract -geometry 200% -blur 0x0.5 \
       -morphology erode square:1 -geometry 50% \) \
    -compose CopyOpacity -composite -shave 1 outputfilename.png

Explanation

This is rather a bit longer than the simple answers previously given, but it gives much better results: (1) The quality is superior due to antialiased alpha, and (2) only the background is removed as opposed to a single color. ("Background" is defined as approximately the same color as the top left pixel, using a floodfill from the picture edges.)

Additionally, the alpha channel is also eroded by half a pixel to avoid halos. Of course, ImageMagick's morphological operations don't (yet?) work at the subpixel level, so you can see I am blowing up the alpha channel to 200% before eroding.

Comparison of results

Here is a comparison of the simple approach ("-fuzz 2% -transparent white") versus my solution, when run on the ImageMagick logo. I've flattened both transparent images onto a saddle brown background to make the differences apparent (click for originals).

Notice how the Wizard's beard has disappeared in the simple approach. Compare the edges of the Wizard to see how antialiased alpha helps the figure blend smoothly into the background.

Of course, I completely admit there are times when you may wish to use the simpler solution. (For example: It's a heck of a lot easier to remember and if you're converting to GIF, you're limited to 1-bit alpha anyhow.)

mktrans shell script

Since it's unlikely you'll want to type this command repeatedly, I recommend wrapping it in a script. You can download a BASH shell script from github which performs my suggested solution. It can be run on multiple files in a directory and includes helpful comments in case you want to tweak things.

bg_removal script

By the way, ImageMagick actually comes with a script called "bg_removal" which uses floodfill in a similar manner as my solution. However, the results are not great because it still uses 1-bit alpha. Also, the bg_removal script runs slower and is a little bit trickier to use (it requires you to specify two different fuzz values). Here's an example of the output from bg_removal.

 <Grid >
    <Grid.ColumnDefinitions>
        <ColumnDefinition Width="*"/>
    </Grid.ColumnDefinitions>
    <Button Command="{Binding ClickCommand}" Width="100" Height="100" Content="wefwfwef"/>
</Grid>

the code behind for the window:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
        DataContext = new ViewModelBase();
    }
}

The ViewModel:

public class ViewModelBase
{
    private ICommand _clickCommand;
    public ICommand ClickCommand
    {
        get
        {
            return _clickCommand ?? (_clickCommand = new CommandHandler(() => MyAction(), ()=> CanExecute));
        }
    }
     public bool CanExecute
     {
        get
        {
            // check if executing is allowed, i.e., validate, check if a process is running, etc. 
            return true/false;
        }
     }

    public void MyAction()
    {

    }
}

Command Handler:

 public class CommandHandler : ICommand
{
    private Action _action;
    private Func<bool> _canExecute;

    /// <summary>
    /// Creates instance of the command handler
    /// </summary>
    /// <param name="action">Action to be executed by the command</param>
    /// <param name="canExecute">A bolean property to containing current permissions to execute the command</param>
    public CommandHandler(Action action, Func<bool> canExecute)
    {
        _action = action;
        _canExecute = canExecute;
    }

    /// <summary>
    /// Wires CanExecuteChanged event 
    /// </summary>
    public event EventHandler CanExecuteChanged
    {
        add { CommandManager.RequerySuggested += value; }
        remove { CommandManager.RequerySuggested -= value; }
    }

    /// <summary>
    /// Forcess checking if execute is allowed
    /// </summary>
    /// <param name="parameter"></param>
    /// <returns></returns>
    public bool CanExecute(object parameter)
    {
        return _canExecute.Invoke();
    }

    public void Execute(object parameter)
    {
        _action();
    }
}

I hope this will give you the idea.

pprint and dir together work great

Check if the data attribute is present, then do the stuff...

$('body').on('click', '.CLICK_BUTTON_CLASS', function (e) {
                        if(e.target.getAttribute('data-title')) {
                            var careerTitle = $(this).attr('data-title');
                            if (careerTitle.length > 0) $('.careerFormTitle').text(careerTitle);
                        }
                });

Edit for iOS 11+ only

Use WKHTTPCookieStore:

let cookie = HTTPCookie(properties: [
    .domain: "example.com",
    .path: "/",
    .name: "MyCookieName",
    .value: "MyCookieValue",
    .secure: "TRUE",
    .expires: NSDate(timeIntervalSinceNow: 31556926)
])! 

webView.configuration.websiteDataStore.httpCookieStore.setCookie(cookie)

Since you are pulling them over from HTTPCookeStorage, you can do this:

let cookies = HTTPCookieStorage.shared.cookies ?? []
for cookie in cookies {
    webView.configuration.websiteDataStore.httpCookieStore.setCookie(cookie)
}

Old answer for iOS 10 and below

If you require your cookies to be set on the initial load request, you can set them on NSMutableURLRequest. Because cookies are just a specially formatted request header this can be achieved like so:

WKWebView * webView = /*set up your webView*/
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:@"http://example.com/index.html"]];
[request addValue:@"TeskCookieKey1=TeskCookieValue1;TeskCookieKey2=TeskCookieValue2;" forHTTPHeaderField:@"Cookie"];
// use stringWithFormat: in the above line to inject your values programmatically
[webView loadRequest:request];

If you require subsequent AJAX requests on the page to have their cookies set, this can be achieved by simply using WKUserScript to set the values programmatically via javascript at document start like so:

WKUserContentController* userContentController = WKUserContentController.new;
WKUserScript * cookieScript = [[WKUserScript alloc] 
    initWithSource: @"document.cookie = 'TeskCookieKey1=TeskCookieValue1';document.cookie = 'TeskCookieKey2=TeskCookieValue2';"
    injectionTime:WKUserScriptInjectionTimeAtDocumentStart forMainFrameOnly:NO];
// again, use stringWithFormat: in the above line to inject your values programmatically
[userContentController addUserScript:cookieScript];
WKWebViewConfiguration* webViewConfig = WKWebViewConfiguration.new;
webViewConfig.userContentController = userContentController;
WKWebView * webView = [[WKWebView alloc] initWithFrame:CGRectMake(/*set your values*/) configuration:webViewConfig];

Combining these two techniques should give you enough tools to transfer cookie values from Native App Land to Web View Land. You can find more info on the cookie javascript API on Mozilla's page if you require some more advanced cookies.

Yeah, it sucks that Apple is not supporting many of the niceties of UIWebView. Not sure if they will ever support them, but hopefully they will get on this soon. Hope this helps!

As Peter already pointed out:

In [4]: type(r.content)
Out[4]: str

You may also want to check r.text.

You might want to do this when you obtain data as objects from databases:

// Suppose 'result' is the end product from some query $query

$result = $mysqli->query($query);
$result = db_result_to_array($result);

function db_result_to_array($result)
{
    $res_array = array();

    for ($count=0; $row = $result->fetch_assoc(); $count++)
        $res_array[$count] = $row;

    return $res_array;
}

Days until Christmas:

>>> import datetime
>>> today = datetime.date.today()
>>> someday = datetime.date(2008, 12, 25)
>>> diff = someday - today
>>> diff.days
86

More arithmetic here.

If I understand correctly, your list has the same type parameter as the container class itself. If this is the case, then:

Type typeParameterType = typeof(T);

If you are in the lucky situation of having object as a type parameter, see Marc's answer.

Assuming you have your hidden input in a jQuery object $myHidden, you then use JavaScript (not jQuery) to get the part after ?:

var myVal = $myHidden.val ();
var tmp = myVal.substr ( myVal.indexOf ( '?' ) + 1 ); // tmp now contains whatever is after ?

Make sure it's within a document ready tagAlternatively, try using .live

$(document).ready(function(){

    $('#content').live('click', function(e) {  
        alert(1);
    });
});

Example:

$(document).ready(function() {_x000D_
    $('#content').click(function(e) {  _x000D_
      alert(1);_x000D_
    });_x000D_
});

#content {_x000D_
    padding: 20px;_x000D_
    background: blue;_x000D_
}

<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>_x000D_
<div id="content">Hello world</div>

As of jQuery 1.7, the .live() method is deprecated. Use .on() to attach event handlers.

$('#content').on( "click", function() {
    alert(1);
});

You're comparing apples to oranges here:

• webHttpBinding is the REST-style binding, where you basically just hit a URL and get back a truckload of XML or JSON from the web service

• basicHttpBinding and wsHttpBinding are two SOAP-based bindings which is quite different from REST. SOAP has the advantage of having WSDL and XSD to describe the service, its methods, and the data being passed around in great detail (REST doesn't have anything like that - yet). On the other hand, you can't just browse to a wsHttpBinding endpoint with your browser and look at XML - you have to use a SOAP client, e.g. the WcfTestClient or your own app.

So your first decision must be: REST vs. SOAP (or you can expose both types of endpoints from your service - that's possible, too).

Then, between basicHttpBinding and wsHttpBinding, there differences are as follows:

• basicHttpBinding is the very basic binding - SOAP 1.1, not much in terms of security, not much else in terms of features - but compatible to just about any SOAP client out there --> great for interoperability, weak on features and security

• wsHttpBinding is the full-blown binding, which supports a ton of WS-* features and standards - it has lots more security features, you can use sessionful connections, you can use reliable messaging, you can use transactional control - just a lot more stuff, but wsHttpBinding is also a lot *heavier" and adds a lot of overhead to your messages as they travel across the network

For an in-depth comparison (including a table and code examples) between the two check out this codeproject article: Differences between BasicHttpBinding and WsHttpBinding

It's not a padding but or the shadow of the background drawable or a problem with the minHeight and minWidth.

If you still want the nice ripple affect, you can make your own button style using the ?attr/selectableItemBackground:

<style name="Widget.AppTheme.MyCustomButton" parent="Widget.AppCompat.Button.Borderless">
    <item name="android:minHeight">0dp</item>
    <item name="android:minWidth">0dp</item>
    <item name="android:layout_height">48dp</item>
    <item name="android:background">?attr/selectableItemBackground</item>
</style>

And apply it to the button:

<Button 
    style="@style/Widget.AppTheme.MyCustomButton"
    ... />

How about this?

C# Thread.Abort is NOT guaranteed to abort the thread instantaneously. It will probably work when a thread calls Abort on itself but not when a thread calls on another.

Please refer to the documentation: http://msdn.microsoft.com/en-us/library/ty8d3wta.aspx

I have faced this problem writing tools that interact with hardware - you want immediate stop but it is not guaranteed. I typically use some flags or other such logic to prevent execution of parts of code running on a thread (and which I do not want to be executed on abort - tricky).

To make this work work with all browsers including Chrome you need to make the callback function of sort() return -1,0 or 1.

see http://inderpreetsingh.com/2010/12/01/chromes-javascript-sort-array-function-is-different-yet-proper/

function sortUL(selector) {
    $(selector).children("li").sort(function(a, b) {
        var upA = $(a).text().toUpperCase();
        var upB = $(b).text().toUpperCase();
        return (upA < upB) ? -1 : (upA > upB) ? 1 : 0;
    }).appendTo(selector);
}
sortUL("ul.mylist");

You need to select the entire column where you have the dates, so click the "text to columns" button, and select delimited > uncheck all the boxes and go until you click the button finish.

This will make the cell format and then the values will be readed as date.

Hope it will helped.

Use the Figure.savefig() method, like so:

ax = s.hist()  # s is an instance of Series
fig = ax.get_figure()
fig.savefig('/path/to/figure.pdf')

It doesn't have to end in pdf, there are many options. Check out the documentation.

Alternatively, you can use the pyplot interface and just call the savefig as a function to save the most recently created figure:

import matplotlib.pyplot as plt
s.hist()
plt.savefig('path/to/figure.pdf')  # saves the current figure

Something neat...

I wanted to look up an "Exact Town ID" based on a "Partial Exact Town Name" BUT although I had the entire town name I was searching against a list of Partial town names. So I First found the "Exact Town Name" based on the part (which was actually a partial name since the "master list" is partial names unfortunately)... THEN searched for the "Exact Town ID" based on that Exact town name SO all my Vlookups/Index/Match-whatevers....were set to EXACT ....

=INDEX(county_cheatsheet!$E$1:$E$516,MATCH(VLOOKUP(LEFT(D3,3)&"*",county_cheatsheet!$E$1:$E$516,1,FALSE),county_cheatsheet!$E$1:E$516,0))

The lookup of the "first three letters of the partial town name against the list of partial town names is the MATCH(VLOOKUP(LEFT(D3,3)&"*" part

On Windows, the PGDATA directory that the PostgresSQL docs describe is at somewhere like C:\Program Files\PostgreSQL\8.1\data. The data for a particular database is under (for example) C:\Program Files\PostgreSQL\8.1\data\base\100929, where I guess 100929 is the database number.

Because testing port number is not a good practice according to me, my solution is:

define('HTTPS', isset($_SERVER['HTTPS']) && filter_var($_SERVER['HTTPS'], FILTER_VALIDATE_BOOLEAN));

The HTTPSconstant returns TRUE if $_SERVER['HTTPS'] is set and equals to "1", "true", "on" or "yes". Returns FALSE otherwise.

Here is also the code to handle the result:

def foo (a):
    x=a
    y=a*2
    return (x,y)

(x,y) = foo(50)

I used class (strongly-typed version of Enum with parsing and performance improvements). I found it on GitHub, and it should work for .NET 3.5 too. It has some memory overhead since it buffers a dictionary.

I think that there are situations where ignoring the .gitignore is very useful. For instance, when you have multiple teams or a large team working on the same codebase. In that case, you need to have certain conventions, one of those convention is regarding what is ignored at the git repo. It is usually about ignoring files and directories created by IDE or OS, some generated logs, etc.

However, there is a force which is tending to introduce non-conventional changes to .gitignore file. The .gitignore file can be further changed by irresponsible person, by mistake, by a tool that is used, or in some other case.

To have a counter force to this, we can do as followed:

1. The initial .gitignore should reflect convention in team(s),
2. After it is pushed, the .gitignore should be secured by adding .gitignore entry and push that change again.The .gitignore file is "sealed" in this way.

The "sealed" .gitignore file can be changed, just locally, without propagating that changers to other members of team(s). However, if a change is widely agreed throughout the whole team(s) than it is possible to "unseal" it, change it and than "seal" it again. That can't be done by mistake, only intentionally.

Sadly, you cannot be 100% protected from the stupidity, but this way you have done everything you can to prevent stupid things to happen.

If you have relatively small team with very good professionals, than this wouldn't be important, but even those guys would appreciate to have one thing less to worry about.

Using .git/info/exclude is cool when you cannot do anything about infrastructure settings, just covering your own a** not to make a mistake.

From a standing point of what is right and what is wrong I am voting for having .gitignore entry inside .gitignore file, giving everybody the freedom to do locally whatever they want, but not invading others.

You have a few options here:

1. Pass Context as an argument to FeedAdapter and keep it as class field
2. Use dependency injection to inject Context when you need it. I strongly suggest reading about it. There is a great tool for that -- Dagger by Square

3. Get it from any View object. In your case this might work for you:

   holder.pub_image.getContext()

   As pub_image is a ImageView.

You have to write your own transformation. Only decimal, hex and octal numbers are supported with format specifiers.

In Python 3.8+ you can do

import hashlib

with open("your_filename.png", "rb") as f:
    file_hash = hashlib.md5()
    while chunk := f.read(8192):
        file_hash.update(chunk)

print(file_hash.digest())
print(file_hash.hexdigest())  # to get a printable str instead of bytes

On Python 3.7 and below:

with open("your_filename.png", "rb") as f:
    file_hash = hashlib.md5()
    chunk = f.read(8192)
    while chunk:
        file_hash.update(chunk)
        chunk = f.read(8192)

print(file_hash.hexdigest())

This reads the file 8192 (or 2¹³) bytes at a time instead of all at once with f.read() to use less memory.

Consider using hashlib.blake2b instead of md5 (just replace md5 with blake2b in the above snippets). It's cryptographically secure and faster than MD5.

A 2016/2017 update will show you the bad value and column.

A new trace flag will swap the old error for a new 2628 error and will print out the column and offending value. Traceflag 460 is available in the latest cumulative update for 2016 and 2017:

https://support.microsoft.com/en-sg/help/4468101/optional-replacement-for-string-or-binary-data-would-be-truncated

Just make sure that after you've installed the CU that you enable the trace flag, either globally/permanently on the server:

...or with DBCC TRACEON:

https://docs.microsoft.com/en-us/sql/t-sql/database-console-commands/dbcc-traceon-trace-flags-transact-sql?view=sql-server-ver15

In your application android manifest file, under the application tag you can try several of these themes.

Replace

<application
    android:theme="@style/AppTheme" >

with different themes defined by the android system. They can be like:-

android:theme="@android:style/Theme.Black"
android:theme="@android:style/Theme.DeviceDefault"
android:theme="@android:style/Theme.DeviceDefault.Dialog"
android:theme="@android:style/Theme.Holo"
android:theme="@android:style/Theme.Translucent"

Each of these themes will have a different effect on your application like the DeviceDefault.Dialog will make your application look like a dialog box. You should try more of these. You can have a look from the android sdk or simply use auto complete in Eclipse IDE to explore the various available options.

A correct way to define your own theme would be to edit the styles.xml file present in the resources folder of your application.

I was using .NET Framework 4.5 but my new library had .NET Framework 4.5.2 and I got the same issue when I tried to build. I solved it by updating my project from 4.5 to 4.5.2 (same as my library).

If I recall correctly Twig doesn't support || and && operators, but requires or and and to be used respectively. I'd also use parentheses to denote the two statements more clearly although this isn't technically a requirement.

{%if ( fields | length > 0 ) or ( trans_fields | length > 0 ) %}

Expressions

Expressions can be used in {% blocks %} and ${ expressions }.

Operator    Description
==          Does the left expression equal the right expression?
+           Convert both arguments into a number and add them.
-           Convert both arguments into a number and substract them.
*           Convert both arguments into a number and multiply them.
/           Convert both arguments into a number and divide them.
%           Convert both arguments into a number and calculate the rest of the integer division.
~           Convert both arguments into a string and concatenate them.
or          True if the left or the right expression is true.
and         True if the left and the right expression is true.
not         Negate the expression.

For more complex operations, it may be best to wrap individual expressions in parentheses to avoid confusion:

{% if (foo and bar) or (fizz and (foo + bar == 3)) %}

From all I have read you cannot do exactly what you want without javascript. If you float left before text

<div style="float:left;">widget</div> here is some CONTENT, etc.

Your content wraps as expected. But your widget is in the top left. If you instead put the float after the content

here is some CONTENT, etc. <div style="float:left;">widget</div>

Then your content will wrap the last line to the right of the widget if the last line of content can fit to the right of the widget, otherwise no wrapping is done. To make borders and backgrounds actually include the floated area in the previous example, most people add:

here is some CONTENT, etc. <div style="float:left;">widget</div><div style="clear:both;"></div>

In your question you are using bootstrap which just adds row-fluid::after { content: ""} which resolves the border/background issue.

Moving your content up will give you the one line wrap : http://jsfiddle.net/jJNPY/34/

  <div class="container-fluid">
  <div class="row-fluid">
    <div class="offset1 span8 pull-right">
    ... Widget 1...
    </div>
    .... a lot of content ....
    <div class="span8" style="margin-left: 0;">
    ... Widget 2...
    </div>


  </div>

</div><!--/.fluid-container-->

i++ is the standard use of a loop, but not the only way. Try incrementing by 3 each time:

 for (int i = 0; i < theData.Length - 2; i+=3) 
    { 

        // use theData[i], theData[i+1], theData[i+2]

    } 

This worked for me from within Fragment:

Fragment frg = null;
Class fragmentClass;
fragmentClass = MainFragment.class;

try {
    frg = (android.support.v4.app.Fragment)     
    fragmentClass.newInstance();
} catch(Exception ex) {
    ex.printStackTrace();
}

getFragmentManager()
    .beginTransaction()
    .replace(R.id.flContent, frg)
    .commit();

Goto the SDK manager in your IDE and install the latest "Intel HAXM" and start the emulator.

If it is throwing the error as

Starting emulator for AVD 'X86'
emulator: ERROR: x86 emulation currently requires hardware acceleration!
Please ensure Intel HAXM is properly installed and usable.
CPU acceleration status: HAX is not installed on this machine (/dev/HAX is missing).

It means that some hardware graphical features are to be assigned.So to overcome this problem just go to the path where you have your Adroid SDK installed.

Windows

C:\Android\SDK\extras\intel\Hardware_Accelerated_Execution_Manager

There you can find the file intelhaxm-android.exe.

Mac OS X

On Mac OSXthere is a IntelHAXM_X.X.X.dmg file, mount it and you'll find an mpkg-file.

Install the file and restart all the applications using android emulator such as(android studio,cmd etc..,).

Now try to open the emulator it will work fine

I prefer this one as it is easier to remember:

git config -l

It will list all useful information such as:

core.filemode=true
core.bare=false
core.logallrefupdates=true

The view containing UITextView will be assigned its size with setBounds by AutoLayout. So, this is what I did. The superview is initially set up all the other constraints as they should be, and in the end I put one special constraint for UITextView's height, and I saved it in an instance variable.

_descriptionHeightConstraint = [NSLayoutConstraint constraintWithItem:_descriptionTextView
                                 attribute:NSLayoutAttributeHeight 
                                 relatedBy:NSLayoutRelationEqual 
                                    toItem:nil 
                                 attribute:NSLayoutAttributeNotAnAttribute 
                                multiplier:0.f 
                                 constant:100];

[self addConstraint:_descriptionHeightConstraint];

In the setBounds method, I then changed the value of the constant.

-(void) setBounds:(CGRect)bounds
{
    [super setBounds:bounds];

    _descriptionTextView.frame = bounds;
    CGSize descriptionSize = _descriptionTextView.contentSize;

    [_descriptionHeightConstraint setConstant:descriptionSize.height];

    [self layoutIfNeeded];
}

Here's an example using xlsxwriter:

import os
import glob
import csv
from xlsxwriter.workbook import Workbook


for csvfile in glob.glob(os.path.join('.', '*.csv')):
    workbook = Workbook(csvfile[:-4] + '.xlsx')
    worksheet = workbook.add_worksheet()
    with open(csvfile, 'rt', encoding='utf8') as f:
        reader = csv.reader(f)
        for r, row in enumerate(reader):
            for c, col in enumerate(row):
                worksheet.write(r, c, col)
    workbook.close()

FYI, there is also a package called openpyxl, that can read/write Excel 2007 xlsx/xlsm files.

Hope that helps.

Java 8 Recursive Solution, If you dont want to use any streams.

UnaryOperator<Long> sumDigit = num -> num <= 0 ? 0 : num % 10 + this.sumDigit.apply(num/10);

How to use

Long sum = sumDigit.apply(123L);

Above solution will work for all positive number. If you want the sum of digits irrespective of positive or negative also then use the below solution.

UnaryOperator<Long> sumDigit = num -> num <= 0 ? 
         (num == 0 ? 0 : this.sumDigit.apply(-1 * num)) 
         : num % 10 + this.sumDigit.apply(num/10);

Try this in the android manifest file corresponding to the activity.

<activity android:windowSoftInputMode="adjustPan"> </activity>

set myPATH="C:\Users\DEB\Downloads\10.1.1.0.4"
cd %myPATH%

• The single quotes do not indicate a string, they make it starts: 'C:\ instead of C:\ so

• %name% is the usual syntax for expanding a variable, the !name! syntax needs to be enabled using the command setlocal ENABLEDELAYEDEXPANSION first, or by running the command prompt with CMD /V:ON.

• Don't use PATH as your name, it is a system name that contains all the locations of executable programs. If you overwrite it, random bits of your script will stop working. If you intend to change it, you need to do set PATH=%PATH%;C:\Users\DEB\Downloads\10.1.1.0.4 to keep the current PATH content, and add something to the end.

I got pretty close to what I wanted by doing something like this

cat my.json | jq '.my.prefix[] | .primary_key + ":", (.sub.prefix[] | "    - " + .sub_key)' | tr -d '"' 

The output of which is close enough to yaml for me to usually import it into other tools without much problem. (I am still looking for a way to basicallt export a subset of the input json)

break x if ((int)strcmp(y, "hello")) == 0

On some implementations gdb might not know the return type of strcmp. That means you would have to cast, otherwise it would always evaluate to true!

1. type Ctrl+Alt+S (or go to Preferences)
2. go to the Plugins tab, press "Browse repositories" button
3. search:
   Visual Paradigm SDE for IntellIJ (Community edition) Modelling Case Tool
4. install it.

You need to install proper software. Now it should works well.

I guess that UML Class Diagram is only available on Ultimate Edition.

To show UML diagram click right mouse button on specific class -> Diagrams -> Show diagram... Or you can in editor click Ctrl+Alt+Shift+U. You could append new classes to diagram by drag and drop. On the top of window you could choose more options. To save UML you should just click on save icon.

You can use FileReader to read the Blob as an ArrayBuffer.

Here's a short example:

var arrayBuffer;
var fileReader = new FileReader();
fileReader.onload = function(event) {
    arrayBuffer = event.target.result;
};
fileReader.readAsArrayBuffer(blob);

Here's a longer example:

// ArrayBuffer -> Blob
var uint8Array  = new Uint8Array([1, 2, 3]);
var arrayBuffer = uint8Array.buffer;
var blob        = new Blob([arrayBuffer]);

// Blob -> ArrayBuffer
var uint8ArrayNew  = null;
var arrayBufferNew = null;
var fileReader     = new FileReader();
fileReader.onload  = function(event) {
    arrayBufferNew = event.target.result;
    uint8ArrayNew  = new Uint8Array(arrayBufferNew);

    // warn if read values are not the same as the original values
    // arrayEqual from: http://stackoverflow.com/questions/3115982/how-to-check-javascript-array-equals
    function arrayEqual(a, b) { return !(a<b || b<a); };
    if (arrayBufferNew.byteLength !== arrayBuffer.byteLength) // should be 3
        console.warn("ArrayBuffer byteLength does not match");
    if (arrayEqual(uint8ArrayNew, uint8Array) !== true) // should be [1,2,3]
        console.warn("Uint8Array does not match");
};
fileReader.readAsArrayBuffer(blob);
fileReader.result; // also accessible this way once the blob has been read

This was tested out in the console of Chrome 27—69, Firefox 20—60, and Safari 6—11.

Here's also a live demonstration which you can play with: https://jsfiddle.net/potatosalad/FbaM6/

Update 2018-06-23: Thanks to Klaus Klein for the tip about event.target.result versus this.result

Reference:

• https://www.w3.org/TR/FileAPI/#dfn-readAsArrayBuffer

The args of print_the_arguments is arguments, so you should use:

struct arg_struct *args = (struct arg_struct *)arguments. 

Destructors provide an implicit way of freeing unmanaged resources encapsulated in your class, they get called when the GC gets around to it and they implicitly call the Finalize method of the base class. If you're using a lot of unmanaged resources it is better to provide an explicit way of freeing those resources via the IDisposable interface. See the C# programming guide: http://msdn.microsoft.com/en-us/library/66x5fx1b.aspx

I know this is an old question but since none of the answers mentioned the large object heap, this might be of use to others who find this question ...

Any memory allocation in .NET that is over 85,000 bytes comes from the large object heap (LOH) not the normal small object heap. Why does this matter? Because the large object heap is not compacted. Which means that the large object heap gets fragmented and in my experience this inevitably leads to out of memory errors.

In the original question the list has 50,000 items in it. Internally a list uses an array, and assuming 32 bit that requires 50,000 x 4bytes = 200,000 bytes (or double that if 64 bit). So that memory allocation is coming from the large object heap.

So what can you do about it?

If you are using a .net version prior to 4.5.1 then about all you can do about it is to be aware of the problem and try to avoid it. So, in this instance, instead of having a list of vehicles you could have a list of lists of vehicles, provided no list ever had more than about 18,000 elements in it. That can lead to some ugly code, but it is viable work around.

If you are using .net 4.5.1 or later then the behaviour of the garbage collector has changed subtly. If you add the following line where you are about to make large memory allocations:

System.Runtime.GCSettings.LargeObjectHeapCompactionMode = System.Runtime.GCLargeObjectHeapCompactionMode.CompactOnce;

it will force the garbage collector to compact the large object heap - next time only.

It might not be the best solution but the following has worked for me:

int tries = 0;
while (tries++ < 2)
{
  try 
  {
    . . some large allocation . .
    return;
  }
  catch (System.OutOfMemoryException)
  {
    System.Runtime.GCSettings.LargeObjectHeapCompactionMode = System.Runtime.GCLargeObjectHeapCompactionMode.CompactOnce;
    GC.Collect();
  }
}

of course this only helps if you have the physical (or virtual) memory available.

The difference in assignment operators is clearer when you use them to set an argument value in a function call. For example:

median(x = 1:10)
x   
## Error: object 'x' not found

In this case, x is declared within the scope of the function, so it does not exist in the user workspace.

median(x <- 1:10)
x    
## [1]  1  2  3  4  5  6  7  8  9 10

In this case, x is declared in the user workspace, so you can use it after the function call has been completed.

There is a general preference among the R community for using <- for assignment (other than in function signatures) for compatibility with (very) old versions of S-Plus. Note that the spaces help to clarify situations like

x<-3
# Does this mean assignment?
x <- 3
# Or less than?
x < -3

Most R IDEs have keyboard shortcuts to make <- easier to type. Ctrl + = in Architect, Alt + - in RStudio (Option + - under macOS), Shift + - (underscore) in emacs+ESS.

If you prefer writing = to <- but want to use the more common assignment symbol for publicly released code (on CRAN, for example), then you can use one of the tidy_* functions in the formatR package to automatically replace = with <-.

library(formatR)
tidy_source(text = "x=1:5", arrow = TRUE)
## x <- 1:5

The answer to the question "Why does x <- y = 5 throw an error but not x <- y <- 5?" is "It's down to the magic contained in the parser". R's syntax contains many ambiguous cases that have to be resolved one way or another. The parser chooses to resolve the bits of the expression in different orders depending on whether = or <- was used.

To understand what is happening, you need to know that assignment silently returns the value that was assigned. You can see that more clearly by explicitly printing, for example print(x <- 2 + 3).

Secondly, it's clearer if we use prefix notation for assignment. So

x <- 5
`<-`(x, 5)  #same thing

y = 5
`=`(y, 5)   #also the same thing

The parser interprets x <- y <- 5 as

`<-`(x, `<-`(y, 5))

We might expect that x <- y = 5 would then be

`<-`(x, `=`(y, 5))

but actually it gets interpreted as

`=`(`<-`(x, y), 5)

This is because = is lower precedence than <-, as shown on the ?Syntax help page.

Or this beautiful round progress bar with HTML5, CSS3 and JavaScript.

Why not simply:

if (typeof myObject.myProperty == "undefined") alert("myProperty is not defined!");

Or if you expect a specific type:

if (typeof myObject.myProperty != "string") alert("myProperty has wrong type or does not exist!");

(Math.floor((Math.random() * 2)) > 0 ? 1 : -1) * Math.floor((Math.random() * 32767))

It could be done in efficient time complexity using KMP algorithm in O(N + M) where N is the length of text and M is the length of the pattern.

This is the implementation and usage:

static class StringExtensions
{
    public static IEnumerable<int> AllIndicesOf(this string text, string pattern)
    {
        if (string.IsNullOrEmpty(pattern))
        {
            throw new ArgumentNullException(nameof(pattern));
        }
        return Kmp(text, pattern);
    }

    private static IEnumerable<int> Kmp(string text, string pattern)
    {
        int M = pattern.Length;
        int N = text.Length;

        int[] lps = LongestPrefixSuffix(pattern);
        int i = 0, j = 0; 

        while (i < N)
        {
            if (pattern[j] == text[i])
            {
                j++;
                i++;
            }
            if (j == M)
            {
                yield return i - j;
                j = lps[j - 1];
            }

            else if (i < N && pattern[j] != text[i])
            {
                if (j != 0)
                {
                    j = lps[j - 1];
                }
                else
                {
                    i++;
                }
            }
        }
    }

    private static int[] LongestPrefixSuffix(string pattern)
    {
        int[] lps = new int[pattern.Length];
        int length = 0;
        int i = 1;

        while (i < pattern.Length)
        {
            if (pattern[i] == pattern[length])
            {
                length++;
                lps[i] = length;
                i++;
            }
            else
            {
                if (length != 0)
                {
                    length = lps[length - 1];
                }
                else
                {
                    lps[i] = length;
                    i++;
                }
            }
        }
        return lps;
    }

and this is an example of how to use it:

static void Main(string[] args)
    {
        string text = "this is a test";
        string pattern = "is";
        foreach (var index in text.AllIndicesOf(pattern))
        {
            Console.WriteLine(index); // 2 5
        }
    }

Python lets you put the indented clause on the same line if it's only one line:

if "exam" in example: print "yes!"

def squared(x): return x * x

class MyException(Exception): pass

Assuming you're in the Object Explorer Details (F7) showing the list of Stored Procedures, click the Filters button and enter the name (or partial name).

    public String encrypt(String str) {
        try {
            // Encode the string into bytes using utf-8
            byte[] utf8 = str.getBytes("UTF8");

            // Encrypt
            byte[] enc = ecipher.doFinal(utf8);

            // Encode bytes to base64 to get a string
            return new sun.misc.BASE64Encoder().encode(enc);
        } catch (javax.crypto.BadPaddingException e) {
        } catch (IllegalBlockSizeException e) {
        } catch (UnsupportedEncodingException e) {
        } catch (java.io.IOException e) {
        }
        return null;
    }

    public String decrypt(String str) {
        try {
            // Decode base64 to get bytes
            byte[] dec = new sun.misc.BASE64Decoder().decodeBuffer(str);

            // Decrypt
            byte[] utf8 = dcipher.doFinal(dec);

            // Decode using utf-8
            return new String(utf8, "UTF8");
        } catch (javax.crypto.BadPaddingException e) {
        } catch (IllegalBlockSizeException e) {
        } catch (UnsupportedEncodingException e) {
        } catch (java.io.IOException e) {
        }
        return null;
    }
}

Here's an example that uses the class:

try {
    // Generate a temporary key. In practice, you would save this key.
    // See also Encrypting with DES Using a Pass Phrase.
    SecretKey key = KeyGenerator.getInstance("DES").generateKey();

    // Create encrypter/decrypter class
    DesEncrypter encrypter = new DesEncrypter(key);

    // Encrypt
    String encrypted = encrypter.encrypt("Don't tell anybody!");

    // Decrypt
    String decrypted = encrypter.decrypt(encrypted);
} catch (Exception e) {
}

Try this:

//KITKAT
i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, CHOOSE_IMAGE_REQUEST);

Use the following in the onActivityResult:

Uri selectedImageURI = data.getData();
input = c.getContentResolver().openInputStream(selectedImageURI);
BitmapFactory.decodeStream(input , null, opts);

I know this is an old question but the most up to date answer is to use the Android Support Design library that will make your life easy.

   int result = tts.setLanguage(Locale.US);
   if (result == TextToSpeech.LANG_MISSING_DATA ||
    result == TextToSpeech.LANG_NOT_SUPPORTED) {
    Log.e("TTS", "Lenguage not supported");
   }
  } else {
   Log.e("TTS", "Initialization failed");
  }
 }
});

// method call
public void buttonSpeak().setOnClickListener(new View.OnClickListener() {

 tts.speak("Text to Speech Test", TextToSpeech.QUEUE_ADD, null);
}

@Override
public void onDestroy() {
 if (tts != null) {
  tts.stop();
  tts.shutdown();
 }
 super.onDestroy();
}

see man nm

GNU nm lists the symbols from object files objfile.... If no object files are listed as arguments, nm assumes the file a.out.

It should normally be done with Request.Form["elementName"].

For example, if you have <input type="text" name="email" /> then you can use Request.Form["email"] to access its value.

They're completely different. Objective C has more in common with Smalltalk than with C++ (well, except for the syntax, really).

MonoDevelop, the IDE associated with Mono Project should be enough for C# development on Linux. Now I don't know any good profilers and other tools for C# development on Linux. But then again mind you, that C# is a language more native to windows. You are better developing C# apps for windows than for linux.

EDIT: When you download MonoDevelop from the Ubuntu Software Center, it will contain pretty much everything you need to get started right away (Compiler, Runtime Environment, IDE). If you would like more information, see the following links:

• http://monodevelop.com/
• http://en.wikipedia.org/wiki/MonoDevelop
• http://en.wikipedia.org/wiki/Mono_%28software%29
• http://www.mono-project.com/Development_Environments

Change the previous button type into a button like this:

<input type="button" name="prev" value="Previous Page" />

Now the Next button would be the default, plus you could also add the default attribute to it so that your browser will highlight it like so:

<input type="submit" name="next" value="Next Page" default />

Try this

1. Go to the properties of the shortcut that points to the program (ALT ENTER or right click->properties); if there is no shortcut to it, you can make it by dragging and dropping the program while holding CTRL SHIFT;

2. Click in the Normal window dropdown, and choose minimized;

3. Save and run the shortcut.

If you are unable to install mysqlclient you can also install pymysql:

pip install pymysql

This works same as MySqldb. After that use pymysql all over instead of MySQLdb

•   is the character entity reference (meant to be easily parseable by humans).
•   is the numeric entity reference (meant to be easily parseable by machines).

They are the same except for the fact that the latter does not need another lookup table to find its actual value. The lookup table is called a DTD, by the way.

You can read more about character entity references in the offical W3C documents.

I was dealing with this issue today, and I knew that I had something encoded as a bytes object that I was trying to serialize as json with json.dump(my_json_object, write_to_file.json). my_json_object in this case was a very large json object that I had created, so I had several dicts, lists, and strings to look at to find what was still in bytes format.

The way I ended up solving it: the write_to_file.json will have everything up to the bytes object that is causing the issue.

In my particular case this was a line obtained through

for line in text:
    json_object['line'] = line.strip()

I solved by first finding this error with the help of the write_to_file.json, then by correcting it to:

for line in text:
    json_object['line'] = line.strip().decode()

Here's another way to accomplish the equivalent of Write-Output. Just put your string in quotes:

"count=$count"

You can make sure this works the same as Write-Output by running this experiment:

"blah blah" > out.txt

Write-Output "blah blah" > out.txt

Write-Host "blah blah" > out.txt

The first two will output "blah blah" to out.txt, but the third one won't.

"help Write-Output" gives a hint of this behavior:

This cmdlet is typically used in scripts to display strings and other objects on the console. However, because the default behavior is to display the objects at the end of a pipeline, it is generally not necessary to use the cmdlet.

In this case, the string itself "count=$count" is the object at the end of a pipeline, and is displayed.

ltrim:

$str = ltrim($str, '0');

If you apply static keyword with any method, it is known as static method.

1. A static method belongs to the class rather than object of a class.
2. A static method invoked without the need for creating an instance of a class.
3. static method can access static data member and can change the value of it.
4. A static method can be accessed just using the name of a class dot static name . . . example : Student9.change();
5. If you want to use non-static fields of a class, you must use a non-static method.

//Program of changing the common property of all objects(static field).

class Student9{  
 int rollno;  
 String name;  
 static String college = "ITS";  

 static void change(){  
 college = "BBDIT";  
 }  

 Student9(int r, String n){  
 rollno = r;  
 name = n;  
 }  

 void display (){System.out.println(rollno+" "+name+" "+college);}  

public static void main(String args[]){  
Student9.change();  

Student9 s1 = new Student9 (111,"Indian");  
Student9 s2 = new Student9 (222,"American");  
Student9 s3 = new Student9 (333,"China");  

s1.display();  
s2.display();  
s3.display();  
}  }

O/P: 111 Indian BBDIT 222 American BBDIT 333 China BBDIT

interestingly, in C# you have the keyword const that translates to C++'s static const, as opposed to readonly which can be only set at constructors and initializations, even by non-constants, ex:

readonly DateTime a = DateTime.Now;

I agree, if you have a const pre-defined array you might as well make it static. At that point you can use this interesting syntax:

//in header file
class a{
    static const int SIZE;
    static const char array[][10];
};
//in cpp file:
const int a::SIZE = 5;
const char array[SIZE][10] = {"hello", "cruel","world","goodbye", "!"};

however, I did not find a way around the constant '10'. The reason is clear though, it needs it to know how to perform accessing to the array. A possible alternative is to use #define, but I dislike that method and I #undef at the end of the header, with a comment to edit there at CPP as well in case if a change.

Sorry, it is a reponse to an old thread, but might still be usefull.

In addition to above reponses, This genrally happens when two columns with same name, even from different tables are included in the same query. for example if we joining two tables city and state where tables have column name e.g. city.name and state.name. when such a query is added to the dataset, ssrs removes the table name or the table alias and only keeps the name, whih eventually appears twice in the query and errors as duplicate key. The best way to avoid it is to use alias such as calling the column names city.name as c_name state.name as s_name. This will resolve the issue.

Here is full example of implementation in cURL and in Python - for authorization and for making API calls

cURL

1. Authorization

You have received access data like this:

Username: johndoe

Password: zznAQOoWyj8uuAgq

Consumer Key: ggczWttBWlTjXCEtk3Yie_WJGEIa

Consumer Secret: uuzPjjJykiuuLfHkfgSdXLV98Ciga

Which you can call in cURL like this:

curl -k -d "grant_type=password&username=Username&password=Password" \

                    -H "Authorization: Basic Base64(consumer-key:consumer-secret)" \

                       https://somedomain.test.com/token

or for this case it would be:

curl -k -d "grant_type=password&username=johndoe&password=zznAQOoWyj8uuAgq" \

                    -H "Authorization: Basic zzRjettzNUJXbFRqWENuuGszWWllX1iiR0VJYTpRelBLZkp5a2l2V0xmSGtmZ1NkWExWzzhDaWdh" \

                      https://somedomain.test.com/token

Answer would be something like:

{
    "access_token": "zz8d62zz-56zz-34zz-9zzf-azze1b8057f8",
    "refresh_token": "zzazz4c3-zz2e-zz25-zz97-ezz6e219cbf6",
    "scope": "default",
    "token_type": "Bearer",
    "expires_in": 3600
}

2. Calling API

Here is how you call some API that uses authentication from above. Limit and offset are just examples of 2 parameters that API could implement. You need access_token from above inserted after "Bearer ".So here is how you call some API with authentication data from above:

curl -k -X GET "https://somedomain.test.com/api/Users/Year/2020/Workers?offset=1&limit=100" -H "accept: application/json" -H "Authorization: Bearer zz8d62zz-56zz-34zz-9zzf-azze1b8057f8"

Python

Same thing from above implemented in Python. I've put text in comments so code could be copy-pasted.

# Authorization data

import base64
import requests

username = 'johndoe'
password= 'zznAQOoWyj8uuAgq'
consumer_key = 'ggczWttBWlTjXCEtk3Yie_WJGEIa'
consumer_secret = 'uuzPjjJykiuuLfHkfgSdXLV98Ciga'
consumer_key_secret = consumer_key+":"+consumer_secret
consumer_key_secret_enc = base64.b64encode(consumer_key_secret.encode()).decode()

# Your decoded key will be something like:
#zzRjettzNUJXbFRqWENuuGszWWllX1iiR0VJYTpRelBLZkp5a2l2V0xmSGtmZ1NkWExWzzhDaWdh


headersAuth = {
    'Authorization': 'Basic '+ str(consumer_key_secret_enc),
}

data = {
  'grant_type': 'password',
  'username': username,
  'password': password
}

## Authentication request

response = requests.post('https://somedomain.test.com/token', headers=headersAuth, data=data, verify=True)
j = response.json()

# When you print that response you will get dictionary like this:

    {
        "access_token": "zz8d62zz-56zz-34zz-9zzf-azze1b8057f8",
        "refresh_token": "zzazz4c3-zz2e-zz25-zz97-ezz6e219cbf6",
        "scope": "default",
        "token_type": "Bearer",
        "expires_in": 3600
    }

# You have to use `access_token` in API calls explained bellow.
# You can get `access_token` with j['access_token'].


# Using authentication to make API calls   

## Define header for making API calls that will hold authentication data

headersAPI = {
    'accept': 'application/json',
    'Authorization': 'Bearer '+j['access_token'],
}

### Usage of parameters defined in your API
params = (
    ('offset', '0'),
    ('limit', '20'),
)

# Making sample API call with authentication and API parameters data

response = requests.get('https://somedomain.test.com/api/Users/Year/2020/Workers', headers=headersAPI, params=params, verify=True)
api_response = response.json()

The answer is misleading because it attempts to fix a problem that is not a problem. You actually CAN have a WHERE CLAUSE in each segment of a UNION. You cannot have an ORDER BY except in the last segment. Therefore, this should work...

select top 2 t1.ID, t1.ReceivedDate
from Table t1
where t1.Type = 'TYPE_1'
-----remove this-- order by ReceivedDate desc
union
select top 2 t2.ID,  t2.ReceivedDate --- add second column
  from Table t2
 where t2.Type = 'TYPE_2'
order by ReceivedDate desc

You can also do it by toggling between display: block on hover and display:none without hover to produce the effect.

This works in bash and zsh, tested on Linux and OS X:

sed 's/regexp/\'$'\n/g'

In general, for $ followed by a string literal in single quotes bash performs C-style backslash substitution, e.g. $'\t' is translated to a literal tab. Plus, sed wants your newline literal to be escaped with a backslash, hence the \ before $. And finally, the dollar sign itself shouldn't be quoted so that it's interpreted by the shell, therefore we close the quote before the $ and then open it again.

Edit: As suggested in the comments by @mklement0, this works as well:

sed $'s/regexp/\\\n/g'

What happens here is: the entire sed command is now a C-style string, which means the backslash that sed requires to be placed before the new line literal should now be escaped with another backslash. Though more readable, in this case you won't be able to do shell string substitutions (without making it ugly again.)

To exit hitting :q will let you quit.

If you want to quit without saving you can hit :q!

A google search on "vim cheatsheet" can provide you with a reference you should print out with a collection of quick shortcuts.

http://www.fprintf.net/vimCheatSheet.html

If your data is already in array form, it's really simple using jQuery:

 $(data.msg).each(function()
 {
     alert(this.value);
     alert(this.label);

     //this refers to the current item being iterated over

     var option = $('<option />');
     option.attr('value', this.value).text(this.label);

     $('#myDropDown').append(option);
 });

.ajax() is more flexible than .getJSON() - for one, getJson is targeted specifically as a GET request to retrieve json; ajax() can request on any verb to get back any content type (although sometimes that's not useful). getJSON internally calls .ajax().

Per Arvand:
Eclipse: Simply type android.R.layout.simple_list_item_1 somewhere in code, hold Ctrl, hover over simple_list_item_1, and from the dropdown that appears select Open declaration in layout/simple_list_item_1.xml. It'll direct you to the contents of the XML.

From there, if you then hover over the resulting simple_list_item_1.xml tab in the Editor, you'll see the file is located at C:\Data\applications\Android\android-sdk\platforms\android-19\data\res\layout\simple_list_item_1.xml (or equivalent location for your installation).

It's too late to answer this question now, but hope this helps someone.

@Eimantas has already given the best answer but the solution won't work if you have two or more tables by the same name under the same server.

I have slightly modified @Eimantas's answer to tackle the above problem.

select Auto_increment as id from information_schema.tables where table_name = 'table_name' and table_schema = 'database_name'

So many ways to do it.

From Workbench: File > Run SQL Script -- then follow prompts

From Windows Command Line:
   Option 1: mysql -u usr -p
             mysql> source file_path.sql
   Option 2: mysql -u usr -p '-e source file_path.sql'
   Option 3: mysql -u usr -p < file_path.sql
   Option 4: put multiple 'source' statements inside of file_path.sql (I do this to drop and recreate schemas/databases which requires multiple files to be run)
             mysql -u usr -p < file_path.sql

If you get errors from the command line, make sure you have previously run

cd {!!>>mysqld.exe home directory here<<!!}
mysqld.exe --initialize 

This must be run from within the mysqld.exe directory, hence the CD.

Hope this is helpful and not just redundant.

I also got the same issue and not able to create a jar, and I found that in Windows-->Prefernces-->Java-->installed JREs By default JRE was added to the build path of newly created java project so just changed it to your prefered JDK.

As others have said, it's macro recording, and you turn it off with q. Here's a nice article about how-to and why it's useful.

And if you need authorized user in templates (e.g. JSP) use

<%@ taglib prefix="sec" uri="http://www.springframework.org/security/tags" %>
<sec:authentication property="principal.yourCustomField"/>

together with

    <dependency>
        <groupId>org.springframework.security</groupId>
        <artifactId>spring-security-taglibs</artifactId>
        <version>${spring-security.version}</version>
    </dependency>

First you should check if books itself isn't null, then simply check whether books[i] != null:

if(books==null) throw new IllegalArgumentException();

for (int i = 0; i < books.length; i++){
   if(books[i] != null){
        total += books[i].getPrice();
   }
}

For browsers implementing the Object.defineProperty() method, the code below generates and returns a function that you can bind to any object you own.

This approach has the advantage of not extending Object.prototype.

The code works by checking if the given object has a __objectID__ property, and by defining it as a hidden (non-enumerable) read-only property if not.

So it is safe against any attempt to change or redefine the read-only obj.__objectID__ property after it has been defined, and consistently throws a nice error instead of silently fail.

Finally, in the quite extreme case where some other code would already have defined __objectID__ on a given object, this value would simply be returned.

var getObjectID = (function () {

    var id = 0;    // Private ID counter

    return function (obj) {

         if(obj.hasOwnProperty("__objectID__")) {
             return obj.__objectID__;

         } else {

             ++id;
             Object.defineProperty(obj, "__objectID__", {

                 /*
                  * Explicitly sets these two attribute values to false,
                  * although they are false by default.
                  */
                 "configurable" : false,
                 "enumerable" :   false,

                 /* 
                  * This closure guarantees that different objects
                  * will not share the same id variable.
                  */
                 "get" : (function (__objectID__) {
                     return function () { return __objectID__; };
                  })(id),

                 "set" : function () {
                     throw new Error("Sorry, but 'obj.__objectID__' is read-only!");
                 }
             });

             return obj.__objectID__;

         }
    };

})();

The best solution is not to use the same element for column and panel:

<div class="row">
    <div class="col-md-3">
        <div class="panel" id="gameplay-away-team">Away Team</div>
    </div>
    <div class="col-md-6">
        <div class="panel" id="gameplay-baseball-field">Baseball Field</div>
    </div>
    <div class="col-md-3">
        <div class="panel" id="gameplay-home-team">Home Team</div>
    </div>
</div>

and some more styles:

#gameplay-baseball-field {
  padding-right: 10px;
  padding-left: 10px;
}

There is also an option to make configuration static in startup.cs so that what you can access it anywhere with ease, static variables are convenient huh!

public Startup(IConfiguration configuration)
{
    Configuration = configuration;
}

internal static IConfiguration Configuration { get; private set; }

This makes configuration accessible anywhere using Startup.Configuration.GetSection... What can go wrong?

Maybe you can use a file, write to file inside function, read from file after it. I have changed e to an array. In this example blanks are used as separator when reading back the array.

#!/bin/bash

declare -a e
e[0]="first"
e[1]="secondddd"

function test1 () {
 e[2]="third"
 e[1]="second"
 echo "${e[@]}" > /tmp/tempout
 echo hi
}

ret=$(test1)

echo "$ret"

read -r -a e < /tmp/tempout
echo "${e[@]}"
echo "${e[0]}"
echo "${e[1]}"
echo "${e[2]}"

Output:

hi
first second third
first
second
third

This is a good one: apps-for-android

Using http.createServer is very low-level and really not useful for creating web applications as-is.

A good framework to use on top of it is Express, and I would seriously suggest using it. You can install it using npm install express.

When you have, you can create a basic application to handle your form:

var express = require('express');
var bodyParser = require('body-parser');
var app     = express();

//Note that in version 4 of express, express.bodyParser() was
//deprecated in favor of a separate 'body-parser' module.
app.use(bodyParser.urlencoded({ extended: true })); 

//app.use(express.bodyParser());

app.post('/myaction', function(req, res) {
  res.send('You sent the name "' + req.body.name + '".');
});

app.listen(8080, function() {
  console.log('Server running at http://127.0.0.1:8080/');
});

You can make your form point to it using:

<form action="http://127.0.0.1:8080/myaction" method="post">

The reason you can't run Node on port 80 is because there's already a process running on that port (which is serving your index.html). You could use Express to also serve static content, like index.html, using the express.static middleware.

Here is my some code

$dir          = '/Images';
$ImagesA = Get_ImagesToFolder($dir);
print_r($ImagesA);

function Get_ImagesToFolder($dir){
    $ImagesArray = [];
    $file_display = [ 'jpg', 'jpeg', 'png', 'gif' ];

    if (file_exists($dir) == false) {
        return ["Directory \'', $dir, '\' not found!"];
    } 
    else {
        $dir_contents = scandir($dir);
        foreach ($dir_contents as $file) {
            $file_type = pathinfo($file, PATHINFO_EXTENSION);
            if (in_array($file_type, $file_display) == true) {
                $ImagesArray[] = $file;
            }
        }
        return $ImagesArray;
    }
}

try Vaadin! Very simple and you'll be able to work the UI with ease as well! www.vaadin.com

foreach ($get_dept as $key5 => $dept_value) {
                if ($request->role_id == 5 || $request->role_id == 6){
                    array_splice($get_dept, $key5, 1);
                }
            }

Is you are in bash shell:

for i in {1..1000}
do
   echo "Welcome $i times"
done

PostgreSQL:

SELECT ... LIMIT [num] OFFSET [num];

You can only call instance method like do() (which is an illegal method name, incidentally) against an instance of the class:

public static void main(String[] args){
  new Foo().doSomething();
}

public void doSomething(){}

Alternatively, make doSomething() static as well, if that works for your design.

If you're using Homebrew /usr/local/bin should already be at the front of $PATH or at least come before /usr/bin. If you now run brew link --force openssl in your terminal window, open a new one and run which openssl in it. It should now show openssl under /usr/local/bin.

Or, once it's already in SSIS, you could create a derived column (as part of some data flow task) with:

(DT_I8)FLOOR((DT_R8)systemDateTime)

But you'd have to test to doublecheck.

I changed scrollable div to be with absolute position, and everything works for me

div.sidebar {
    overflow: hidden;
    background-color: green;
    padding: 5px;
    position: fixed;
    right: 20px;
    width: 40%;
    top: 30px;
    padding: 20px;
    bottom: 30%;
}
div#fixed {
    background: #76a7dc;
    color: #fff;
    height: 30px;
}

div#scrollable {
    overflow-y: scroll;
    background: lightblue;

    position: absolute;
    top:55px; 
    left:20px;
    right:20px;
    bottom:10px;
}

I've written a few methods for convert by Gson library and java 1.8 .
thay are daynamic model for convert.

string to object

object to string

List to string

string to List

HashMap to String

String to JsonObj

//saeedmpt 
public static String convertMapToString(Map<String, String> data) {
    //convert Map  to String
    return new GsonBuilder().setPrettyPrinting().create().toJson(data);
}
public static <T> List<T> convertStringToList(String strListObj) {
    //convert string json to object List
    return new Gson().fromJson(strListObj, new TypeToken<List<Object>>() {
    }.getType());
}
public static <T> T convertStringToObj(String strObj, Class<T> classOfT) {
    //convert string json to object
    return new Gson().fromJson(strObj, (Type) classOfT);
}

public static JsonObject convertStringToJsonObj(String strObj) {
    //convert string json to object
    return new Gson().fromJson(strObj, JsonObject.class);
}

public static <T> String convertListObjToString(List<T> listObj) {
    //convert object list to string json for
    return new Gson().toJson(listObj, new TypeToken<List<T>>() {
    }.getType());
}

public static String convertObjToString(Object clsObj) {
    //convert object  to string json
    String jsonSender = new Gson().toJson(clsObj, new TypeToken<Object>() {
    }.getType());
    return jsonSender;
}

If the list you use for the spinner is an object then you can find its position like this

private int selectSpinnerValue( List<Object> ListSpinner,String myString) 
{
    int index = 0;
    for(int i = 0; i < ListSpinner.size(); i++){
      if(ListSpinner.get(i).getValueEquals().equals(myString)){
          index=i;
          break;
      }
    }
    return index;
}

using:

 int index=selectSpinnerValue(ListOfSpinner,StringEquals);
    spinner.setSelection(index,true);

Another good reason to use pointers would be for forward declarations. In a large enough project they can really speed up compile time.

Use -w in the command: psql -h localhost -p 5432 -U user -w

bash to get file name

fspec="/exp/home1/abc.txt" 
filename="${fspec##*/}"  # get filename
dirname="${fspec%/*}" # get directory/path name

other ways

awk

$ echo $fspec | awk -F"/" '{print $NF}'
abc.txt

sed

$ echo $fspec | sed 's/.*\///'
abc.txt

using IFS

$ IFS="/"
$ set -- $fspec
$ eval echo \${${#@}}
abc.txt

You can get a list of any configured remote URLs with the command git remote -v.

This will give you something like the following:

base    /home/***/htdocs/base (fetch)
base    /home/***/htdocs/base (push)
origin  [email protected]:*** (fetch)
origin  [email protected]:*** (push)

Since placeholder disappear on input, you can use:

input:placeholder-shown{
    //rules for not empty input
}

I suppose subqueries and PIVOT would qualify, as well as multiple joins, unions and the like.

If i am understanding your question, would this work? (you will have to replace with your actual column and table names)

SELECT time_col, COUNT(time_col) As Count
FROM time_table
GROUP BY time_col
WHERE activity_col = 3

Marc's answer should be the correct one, but in .NET 4 you couldn't also go with dynamic type.

This should be used only if you have no control over the classes you return and there are no common ancestors ( usually with interop ) and only if not using dynamic is a lot more painful then using(casting every object in every step :) ).

Few blog post trying to explain when to use dynamic: http://blogs.msdn.com/b/csharpfaq/archive/tags/dynamic/

public dynamic GetSomething()
{
     Hello hello = new Hello();
     Computer computer = new Computer();
     Radio radio = new Radio(); 
     return // anyobject

}

perhaps not the most elegant way to solve this

select  Activity, 
        SUM(Amount) as "Total_Amount",
        2009 AS INCOME_YEAR
from    Activities, Incomes
where Activities.UnitName = ? AND
      Incomes.ActivityId = Activities.ActivityID
GROUP BY Activity
ORDER BY Activity;

UNION

select  Activity, 
        SUM(Amount) as "Total_Amount",
        2008 AS INCOME_YEAR
from Activities, Incomes2008
where Activities.UnitName = ? AND
      Incomes2008.ActivityId = Activities.ActivityID
GROUP BY Activity
ORDER BY Activity;

Since Java 1.7 you can use Files.createFile:

Path pathToFile = Paths.get("/home/joe/foo/bar/myFile.txt");
Files.createDirectories(pathToFile.getParent());
Files.createFile(pathToFile);

You can simply pass more arguments to summarise:

df %>% group_by(grp) %>% summarise(mean(a), mean(b), mean(c), mean(d))

Source: local data frame [3 x 5]

  grp  mean(a)  mean(b)  mean(c) mean(d)
1   1 2.500000 3.500000 2.000000     3.0
2   2 3.800000 3.200000 3.200000     2.8
3   3 3.666667 3.333333 2.333333     3.0

you can also use the randomizeMatrix function in the R package picante

example:

test <- matrix(c(1,1,0,1,0,1,0,0,1,0,0,1,0,1,0,0),nrow=4,ncol=4)
> test
     [,1] [,2] [,3] [,4]
[1,]    1    0    1    0
[2,]    1    1    0    1
[3,]    0    0    0    0
[4,]    1    0    1    0

randomizeMatrix(test,null.model = "frequency",iterations = 1000)

     [,1] [,2] [,3] [,4]
[1,]    0    1    0    1
[2,]    1    0    0    0
[3,]    1    0    1    0
[4,]    1    0    1    0

randomizeMatrix(test,null.model = "richness",iterations = 1000)

     [,1] [,2] [,3] [,4]
[1,]    1    0    0    1
[2,]    1    1    0    1
[3,]    0    0    0    0
[4,]    1    0    1    0
> 

The option null.model="frequency" maintains column sums and richness maintains row sums. Though mainly used for randomizing species presence absence datasets in community ecology it works well here.

This function has other null model options as well, check out following link for more details (page 36) of the picante documentation

An integral type representing the smallest value possible. In other words your program should think in cents not in dollars/euros.

This should not stop you from having the gui translate it back to dollars/euros.

I'm using Batik for this. The complete Delphi code:

procedure ExecNewProcess(ProgramName : String; Wait: Boolean);
var
  StartInfo : TStartupInfo;
  ProcInfo : TProcessInformation;
  CreateOK : Boolean;
begin
  FillChar(StartInfo, SizeOf(TStartupInfo), #0);
  FillChar(ProcInfo, SizeOf(TProcessInformation), #0);
  StartInfo.cb := SizeOf(TStartupInfo);
  CreateOK := CreateProcess(nil, PChar(ProgramName), nil, nil, False,
              CREATE_NEW_PROCESS_GROUP + NORMAL_PRIORITY_CLASS,
              nil, nil, StartInfo, ProcInfo);
  if CreateOK then begin
    //may or may not be needed. Usually wait for child processes
    if Wait then
      WaitForSingleObject(ProcInfo.hProcess, INFINITE);
  end else
    ShowMessage('Unable to run ' + ProgramName);

  CloseHandle(ProcInfo.hProcess);
  CloseHandle(ProcInfo.hThread);
end;

procedure ConvertSVGtoPNG(aFilename: String);
const
  ExecLine = 'c:\windows\system32\java.exe -jar C:\Apps\batik-1.7\batik-rasterizer.jar ';
begin
  ExecNewProcess(ExecLine + aFilename, True);
end;

You want the CASE statement:

SELECT
  CASE 
    WHEN @SelectField1 = 1 THEN Field1
    WHEN @SelectField2 = 1 THEN Field2
    ELSE NULL
  END AS NewField
FROM Table

EDIT: My example is for combining the two fields into one field, depending on the parameters supplied. It is a one-or-neither solution (not both). If you want the possibility of having both fields in the output, use Quassnoi's solution.

I don't like this behavior, but this is how Python works. The question has already been answered by others, but for completeness, let me point out that Python 2 has more such quirks.

def f(x):
    return x

def main():
    print f(3)
    if (True):
        print [f for f in [1, 2, 3]]

main()

Python 2.7.6 returns an error:

Traceback (most recent call last):
  File "weird.py", line 9, in <module>
    main()
  File "weird.py", line 5, in main
    print f(3)
UnboundLocalError: local variable 'f' referenced before assignment

Python sees the f is used as a local variable in [f for f in [1, 2, 3]], and decides that it is also a local variable in f(3). You could add a global f statement:

def f(x):
    return x

def main():
    global f
    print f(3)
    if (True):
        print [f for f in [1, 2, 3]]

main()

It does work; however, f becomes 3 at the end... That is, print [f for f in [1, 2, 3]] now changes the global variable f to 3, so it is not a function any more.

Fortunately, it works fine in Python3 after adding the parentheses to print.

I asked a question that kinda duplicated on this topic a while back, and after excessive research, and seeing a lot of information missing that should be here, I feel I have something valuable to add to this older post.

• Firstly I want to address that there are several ways to obtain the value of a property and store it in a dynamic Variable. The first most popular, and easiest way IMHO would be:

let properyValue = element.style['enter-a-property'];

however I rarely go this route because it doesn't work on property values assigned via style-sheets. To give you an example, I'll demonstrate with a bit of pseudo code.

 let elem = document.getElementById('someDiv');
 let cssProp = elem.style['width'];

Using the code example above; if the width property of the div element that was stored in the 'elem' variable was styled in a CSS style-sheet, and not styled inside of its HTML tag, you are without a doubt going to get a return value of undefined stored inside of the cssProp variable. The undefined value occurs because in-order to get the correct value, the code written inside a CSS Style-Sheet needs to be computed in-order to get the value, therefore; you must use a method that will compute the value of the property who's value lies within the style-sheet.

• Henceforth the getComputedStyle() method!

function getCssProp(){
  let ele = document.getElementById("test");
  let cssProp = window.getComputedStyle(ele,null).getPropertyValue("width");
}

W3Schools getComputedValue Doc This gives a good example, and lets you play with it, however, this link Mozilla CSS getComputedValue doc talks about the getComputedValue function in detail, and should be read by any aspiring developer who isn't totally clear on this subject.

• As a side note, the getComputedValue method only gets, it does not set. This, obviously is a major downside, however there is a method that gets from CSS style-sheets, as well as sets values, though it is not standard Javascript. The JQuery method...

$(selector).css(property,value)

...does get, and does set. It is what I use, the only downside is you got to know JQuery, but this is honestly one of the very many good reasons that every Javascript Developer should learn JQuery, it just makes life easy, and offers methods, like this one, which is not available with standard Javascript. Hope this helps someone!!!

I ended up with creating a base fragment and make all fragments in my app extend it

public class BaseFragment extends Fragment {

    private boolean mStateSaved;

    @CallSuper
    @Override
    public void onSaveInstanceState(Bundle outState) {
        mStateSaved = true;
        super.onSaveInstanceState(outState);
    }

    /**
     * Version of {@link #show(FragmentManager, String)} that no-ops when an IllegalStateException
     * would otherwise occur.
     */
    public void showAllowingStateLoss(FragmentManager manager, String tag) {
        // API 26 added this convenient method
        if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
            if (manager.isStateSaved()) {
                return;
            }
        }

        if (mStateSaved) {
            return;
        }

        show(manager, tag);
    }
}

Then when I try to show a fragment I use showAllowingStateLoss instead of show

like this:

MyFragment.newInstance()
.showAllowingStateLoss(getFragmentManager(), MY_FRAGMENT.TAG);

I came up to this solution from this PR: https://github.com/googlesamples/easypermissions/pull/170/files
