UPDATE - I do not have Total DNS enabled at GoDaddy because the domain is hosted at DiscountASP. As such, I could not add an A Record and that is why GoDaddy was only offering to forward my subdomain to a different site. I finally realized that I had to go to DiscountASP to add the A Record to point to DreamHost. Now waiting to see if it all works!

Of course, use the stinkin' IP! I'm not sure why that wasn't registering for me. I guess their helper text example of pointing to another url was throwing me off.

Thanks for both of the replies. I 'got it' as soon as I read Bryant's response which was first but Saif kicked it up a notch and added a little more detail.

Thanks!

We can use following three ways in Shell Scripting for ternary operator :

    [ $numVar == numVal ] && resVar="Yop" || resVar="Nop"

Or

    resVar=$([ $numVar == numVal ] && echo "Yop" || echo "Nop")

Or

    (( numVar == numVal ? (resVar=1) : (resVar=0) ))

This works

String x = "22/06/2012";
String y = "25/10/2014";

String datestart = x;
String datestop = y;

//DateTimeFormatter format = DateTimeFormat.forPattern("dd/mm/yyyy");
SimpleDateFormat  format = new SimpleDateFormat("dd/mm/yyyy");

Date d1 = null;
Date d2 = null;

try {
    d1 =  format.parse(datestart);
    d2 = format.parse(datestop);

    DateTime dt1 = new DateTime(d1);
    DateTime dt2 = new DateTime(d2);

    //Period
    period = new Period (dt1,dt2);

    //calculate days
    int days = Days.daysBetween(dt1, dt2).getDays();


} catch (ParseException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Done by having it like that:

view = inflater.inflate(R.layout.entry_detail, container, false);
TextView tp1= (TextView) view.findViewById(R.id.tp1);
LinearLayout layone= (LinearLayout) view.findViewById(R.id.layone);
tp1.setVisibility(View.VISIBLE);
layone.setVisibility(View.VISIBLE);

Copy Azure database data to local database: Now you can use the SQL Server Management Studio to do this as below:

• Connect to the SQL Azure database.
• Right click the database in Object Explorer.
• Choose the option "Tasks" / "Deploy Database to SQL Azure".
• In the step named "Deployment Settings", connect local SQL Server and create New database.

"Next" / "Next" / "Finish"

I struggled for a while about this. Stupid rule for __init__. It is two "_" together to be "__"

Once you know this:

• You can create a Date by calling the constructor with milliseconds since Jan 1, 1970.
• The valueOf() a Date is the number of milliseconds since Jan 1, 1970
• There are 60,000 milliseconds in a minute :-]

...it isn't so hard.

In the code below, a new Date is created by subtracting the appropriate number of milliseconds from myEndDateTime:

var MS_PER_MINUTE = 60000;
var myStartDate = new Date(myEndDateTime - durationInMinutes * MS_PER_MINUTE);

This will return the maximum value in a matrix

max(M1(:))

This will return the row and the column of that value

[x,y]=ind2sub(size(M1),max(M1(:)))

For minimum just swap the word max with min and that's all.

What gets returned is the return value of executing this command. What you see in while executing it directly is the output of the command in stdout. That 0 is returned means, there was no error in execution.

Use popen etc for capturing the output .

Some thing along this line:

import subprocess as sub
p = sub.Popen(['your command', 'arg1', 'arg2', ...],stdout=sub.PIPE,stderr=sub.PIPE)
output, errors = p.communicate()
print output

or

import os
p = os.popen('command',"r")
while 1:
    line = p.readline()
    if not line: break
    print line

ON SO : Popen and python

If it's after 1999, and you're still using Expires or Pragma, you're doing it wrong.

1. Make sure all versions are same for each projects click each projects and see the version here Project > Properties > Application > Target .NET framework

2. a. Go to Tools > Nuget Package Manager > Package Manager Console Type Update-Package -Reinstall (if not working proceed to 2.b)

   b. THIS IS CRITICAL BUT THE BIGGEST POSSIBILITY THAT WILL WORK. Remove < Target > Maybe with multiple lines < /Target > usually found at the bottom part of .csproj.

3. Save, load and build the solution.

You can try like this:

SELECT PARSENAME('$'+ Convert(varchar,Convert(money,@MoneyValue),1),2)

Short-circuiting behavior in operator and, or:

Let's first define a useful function to determine if something is executed or not. A simple function that accepts an argument, prints a message and returns the input, unchanged.

>>> def fun(i):
...     print "executed"
...     return i
... 

One can observe the Python's short-circuiting behavior of and, or operators in the following example:

>>> fun(1)
executed
1
>>> 1 or fun(1)    # due to short-circuiting  "executed" not printed
1
>>> 1 and fun(1)   # fun(1) called and "executed" printed 
executed
1
>>> 0 and fun(1)   # due to short-circuiting  "executed" not printed 
0

Note: The following values are considered by the interpreter to mean false:

        False    None    0    ""    ()    []     {}

Short-circuiting behavior in function: any(), all():

Python's any() and all() functions also support short-circuiting. As shown in the docs; they evaluate each element of a sequence in-order, until finding a result that allows an early exit in the evaluation. Consider examples below to understand both.

The function any() checks if any element is True. It stops executing as soon as a True is encountered and returns True.

>>> any(fun(i) for i in [1, 2, 3, 4])   # bool(1) = True
executed
True
>>> any(fun(i) for i in [0, 2, 3, 4])   
executed                               # bool(0) = False
executed                               # bool(2) = True
True
>>> any(fun(i) for i in [0, 0, 3, 4])
executed
executed
executed
True

The function all() checks all elements are True and stops executing as soon as a False is encountered:

>>> all(fun(i) for i in [0, 0, 3, 4])
executed
False
>>> all(fun(i) for i in [1, 0, 3, 4])
executed
executed
False

Short-circuiting behavior in Chained Comparison:

Additionally, in Python

Comparisons can be chained arbitrarily; for example, x < y <= z is equivalent to x < y and y <= z, except that y is evaluated only once (but in both cases z is not evaluated at all when x < y is found to be false).

>>> 5 > 6 > fun(3)    # same as:  5 > 6 and 6 > fun(3)
False                 # 5 > 6 is False so fun() not called and "executed" NOT printed
>>> 5 < 6 > fun(3)    # 5 < 6 is True 
executed              # fun(3) called and "executed" printed
True
>>> 4 <= 6 > fun(7)   # 4 <= 6 is True  
executed              # fun(3) called and "executed" printed
False
>>> 5 < fun(6) < 3    # only prints "executed" once
executed
False
>>> 5 < fun(6) and fun(6) < 3 # prints "executed" twice, because the second part executes it again
executed
executed
False

Edit:
One more interesting point to note :- Logical and, or operators in Python returns an operand's value instead of a Boolean (True or False). For example:

Operation x and y gives the result if x is false, then x, else y

^{Unlike in other languages e.g. &&, || operators in C that return either 0 or 1.}

Examples:

>>> 3 and 5    # Second operand evaluated and returned 
5                   
>>> 3  and ()
()
>>> () and 5   # Second operand NOT evaluated as first operand () is  false
()             # so first operand returned 

Similarly or operator return left most value for which bool(value) == True else right most false value (according to short-circuiting behavior), examples:

>>> 2 or 5    # left most operand bool(2) == True
2    
>>> 0 or 5    # bool(0) == False and bool(5) == True
5
>>> 0 or ()
()

So, how is this useful? One example is given in Practical Python By Magnus Lie Hetland:
Let’s say a user is supposed to enter his or her name, but may opt to enter nothing, in which case you want to use the default value '<Unknown>'. You could use an if statement, but you could also state things very succinctly:

In [171]: name = raw_input('Enter Name: ') or '<Unknown>'
Enter Name: 

In [172]: name
Out[172]: '<Unknown>'

In other words, if the return value from raw_input is true (not an empty string), it is assigned to name (nothing changes); otherwise, the default '<Unknown>' is assigned to name.

to_timestamp()

You need to use to_timestamp() to convert your string to a proper timestamp value:

to_timestamp('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')

to_date()

If your column is of type DATE (which also supports seconds), you need to use to_date()

to_date('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')

Example

To get this into a where condition use the following:

select * 
from TableA 
where startdate >= to_timestamp('12-01-2012 21:24:00', 'dd-mm-yyyy hh24:mi:ss')
  and startdate <= to_timestamp('12-01-2012 21:25:33', 'dd-mm-yyyy hh24:mi:ss')

Note

You never need to use to_timestamp() on a column that is of type timestamp.

Basic overview of hashing and encryption/decryption techniques are.

Hashing:

If you hash any plain text again you can not get the same plain text from hashed text. Simply, It's a one-way process.

Encryption and Decryption:

If you encrypt any plain text with a key again you can get same plain text by doing decryption on encrypted text with same(symetric)/diffrent(asymentric) key.

UPDATE: To address the points mentioned in the edited question.

1. When to use hashes vs encryptions

Hashing is useful if you want to send someone a file. But you are afraid that someone else might intercept the file and change it. So a way that the recipient can make sure that it is the right file is if you post the hash value publicly. That way the recipient can compute the hash value of the file received and check that it matches the hash value.

Encryption is good if you say have a message to send to someone. You encrypt the message with a key and the recipient decrypts with the same (or maybe even a different) key to get back the original message. credits

2. What makes a hash or encryption algorithm different (from a theoretical/mathematical level) i.e. what makes hashes irreversible (without aid of a rainbow tree)

Basically hashing is an operation that loses information but not encryption. Let's look at the difference in simple mathematical way for our easy understanding, of course both have much more complicated mathematical operation with repetitions involved in it

Encryption/Decryption (Reversible):

---

Addition:

4 + 3 = 7  

This can be reversed by taking the sum and subtracting one of the addends

7 - 3 = 4     

Multiplication:

4 * 5 = 20  

This can be reversed by taking the product and dividing by one of the factors

20 / 4 = 5    

So, here we could assume one of the addends/factors is a decrpytion key and result(7,20) is an excrypted text.

---

Hashing (Not Reversible):

---

Modulo division:

22 % 7 = 1   

This can not be reversed because there is no operation that you can do to the quotient and the dividend to reconstitute the divisor (or vice versa).

Can you find an operation to fill in where the '?' is?

1  ?  7 = 22  
1  ?  22 = 7

So hash functions have the same mathematical quality as modulo division and looses the information.

For users of modern DataTables (1.10 and above), all the answers and examples on this page are for the old api, not the new. I had a very hard time finding a newer example but finally did find this DT forum post (TL;DR for most folks) which led me to this concise example.

The example code worked for me after I finally noticed the $() selector syntax immediately surrounding the html string. You have to add a node not a string.

That example really is worth looking at but, in the spirit of SO, if you just want to see a snippet of code that works:

var table = $('#example').DataTable();
  table.rows.add( $(
          '<tr>'+
          '  <td>Tiger Nixon</td>'+
          '  <td>System Architect</td>'+
          '  <td>Edinburgh</td>'+
          '  <td>61</td>'+
          '  <td>2011/04/25</td>'+
          '  <td>$3,120</td>'+
          '</tr>'
  ) ).draw();

The careful reader might note that, since we are adding only one row of data, that table.row.add(...) should work as well and did for me.

In order to set textColor, BottomNavigationView has two style properties you can set directly from the xml:

• itemTextAppearanceActive
• itemTextAppearanceInactive

In your layout.xml file:

<com.google.android.material.bottomnavigation.BottomNavigationView
            android:id="@+id/bnvMainNavigation"
            style="@style/NavigationView"/>
  

In your styles.xml file:

    <style name="NavigationView" parent="Widget.MaterialComponents.BottomNavigationView">
      <item name="itemTextAppearanceActive">@style/ActiveText</item>
      <item name="itemTextAppearanceInactive">@style/InactiveText</item>
    </style>
    <style name="ActiveText">
      <item name="android:textColor">@color/colorPrimary</item>
    </style>
    <style name="InactiveText">
      <item name="android:textColor">@color/colorBaseBlack</item>
    </style>

I found a workaround a week ago. You can use direct commands with "ExecuteCommand":

MDataContext dc = new MDataContext();
var flag = (from f in dc.Flags
                   where f.Code == Code
                   select f).First();
_refresh = Convert.ToBoolean(flagRefresh.Value);
if (_refresh)
{
    dc.ExecuteCommand("update Flags set value = 0 where code = {0}", Code);
}

In the ExecuteCommand statement, you can send the query directly, with the value for the specific record you want to update.

value = 0 --> 0 is the new value for the record;

code = {0} --> is the field where you will send the filter value;

Code --> is the new value for the field;

I hope this reference helps.

I am using this code, which I find more practical than the accepted answer above:

List<Thing> thingList = new ArrayList<>(thingSet);
thingList.sort((thing1, thing2) -> thing1.getName().compareToIgnoreCase(thing2.getName()));

Try using clockwork gem to schedule tasks. Follow the steps provided in this link.

http://fuzzyblog.io/blog/rails/2017/05/11/adding-cron-to-a-dockerized-rails-application-using-clockwork.html

You can call the rake task inside lib/clock.rb file as below.

every(1.day, 'Import large data from csv files', :at => '5:00') do |job|
  `rake 'portal:import_data_from_csv'`
end

Create a separate container in docker-compose file & run the below command inside the container.

command: bundle exec clockwork lib/clock.rb

Keep in mind that tables in relational databases are just sets of rows. And sets in mathematics are unordered collections. There is no first or last row; no previous row or next row.

You'll have to sort your set of unordered rows by some field first, and then you are free the iterate through the resultset in the order you defined.

Since you have an auto incrementing field, I assume you want that to be the sorting field. In that case, you may want to do the following:

SELECT    *
FROM      your_table
ORDER BY  your_auto_increment_field DESC
LIMIT     1;

See how we're first sorting the set of unordered rows by the your_auto_increment_field (or whatever you have it called) in descending order. Then we limit the resultset to just the first row with LIMIT 1.

If you can make the assumption that all children are either Element Nodes or Text Nodes, then this is one solution.

To get all child text nodes as a jquery collection:

$('selector').clone().children().remove().end().contents();

To get a copy of the original element with non-text children removed:

$('selector').clone().children().remove().end();

In Python 2, I didn't have a lot luck with super(). I used the answer from jimifiki on this SO thread how to refer to a parent method in python?. Then, I added my own little twist to it, which I think is an improvement in usability (Especially if you have long class names).

Define the base class in one module:

 # myA.py

class A():     
    def foo( self ):
        print "foo"

Then import the class into another modules as parent:

# myB.py

from myA import A as parent

class B( parent ):
    def foo( self ):
        parent.foo( self )   # calls 'A.foo()'

POST variables should be accessible via the request object: HttpRequest.getParameterMap(). The exception is if the form is sending multipart MIME data (the FORM has enctype="multipart/form-data"). In that case, you need to parse the byte stream with a MIME parser. You can write your own or use an existing one like the Apache Commons File Upload API.

Scenario 1: If you want to undo the last commit say 8123b7e04b3, below is the command(this worked for me):

git push origin +8123b7e04b3^:<branch_name>

Output looks like below:

Total 0 (delta 0), reused 0 (delta 0)
To https://testlocation/code.git
 + 8123b7e...92bc500 8123b7e04b3^ -> master (forced update)

Note: To update the change to your local code (to remove the commit locally as well) :

$ git reset --hard origin/<branchName>
Message displayed is :    HEAD is now at 8a3902a comments_entered_for_commit

Additional info: Scenario 2: In some situation, you may want to revert back what you just undo'ed (basically undo the undo) through the previous command, then use the below command:

git reset --hard 8123b7e04b3

Output:

HEAD is now at cc6206c Comment_that_was_entered_for_commit

If you are using Jquery 1.6 or above, use prop to access the value.

$(document).prop('scrollHeight')

Previous versions used to get the value from attr but not post 1.6.

Referring to the first thread / another possibility VS cant open or find pdb file of the process is when you have your executable running in the background. I was working with mpiexec and ran into this issue. Always check your task manager and kill any exec process that your gonna build in your project. Once I did that, it debugged or built fine.

Also, if you try to continue with the warning , the breakpoints would not be hit and it would not have the current executable

Building off Ali's answer, I would recommend an extension method that allows you to optionally pass in the encoding you want to use:

using System.Text;
public static class StringExtensions
{
    /// <summary>
    /// Creates a byte array from the string, using the 
    /// System.Text.Encoding.Default encoding unless another is specified.
    /// </summary>
    public static byte[] ToByteArray(this string str, Encoding encoding = Encoding.Default)
    {
        return encoding.GetBytes(str);
    }
}

And use it like below:

string foo = "bla bla";

// default encoding
byte[] default = foo.ToByteArray();

// custom encoding
byte[] unicode = foo.ToByteArray(Encoding.Unicode);

Use first

which python

This will give the output as the location where my python interpreter (binary) is present.

This output could be any such as

/usr/bin/python

or

/bin/python

Now appropriately select the shebang line and use it.

To generalize we can use:

#!/usr/bin/env

or

#!/bin/env

Quick Answer

Use index_col=False instead of index_col=None when you have delimiters at the end of each line to turn off index column inference and discard the last column.

More Detail

After looking at the data, there is a comma at the end of each line. And this quote (the documentation has been edited since the time this post was created):

index_col: column number, column name, or list of column numbers/names, to use as the index (row labels) of the resulting DataFrame. By default, it will number the rows without using any column, unless there is one more data column than there are headers, in which case the first column is taken as the index.

from the documentation shows that pandas believes you have n headers and n+1 data columns and is treating the first column as the index.

EDIT 10/20/2014 - More information

I found another valuable entry that is specifically about trailing limiters and how to simply ignore them:

If a file has one more column of data than the number of column names, the first column will be used as the DataFrame’s row names: ...

Ordinarily, you can achieve this behavior using the index_col option.

There are some exception cases when a file has been prepared with delimiters at the end of each data line, confusing the parser. To explicitly disable the index column inference and discard the last column, pass index_col=False: ...

If the OpenSSL headers are in the openssl sub-directory of the current directory, use:

gcc -I. -o Opentest Opentest.c -lcrypto

The pre-processor looks to create a name such as "./openssl/ssl.h" from the "." in the -I option and the name specified in angle brackets. If you had specified the names in double quotes (#include "openssl/ssl.h"), you might never have needed to ask the question; the compiler on Unix usually searches for headers enclosed in double quotes in the current directory automatically, but it does not do so for headers enclosed in angle brackets (#include <openssl/ssl.h>). It is implementation defined behaviour.

You don't say where the OpenSSL libraries are - you might need to add an appropriate option and argument to specify that, such as '-L /opt/openssl/lib'.

You can change the actual width/height attributes like this:

var theImg = document.getElementById('theImgId');
theImg.height = 150;
theImg.width = 150;

Or by using DBIs sqlRownamesToColumn

library(DBI)
sqlRownamesToColumn(df)

I tried with this method and it significantly reduced my database insert execution time.

List<string> toinsert = new List<string>();
StringBuilder insertCmd = new StringBuilder("INSERT INTO tabblename (col1, col2, col3) VALUES ");

foreach (var row in rows)
{
      // the point here is to keep values quoted and avoid SQL injection
      var first = row.First.Replace("'", "''")
      var second = row.Second.Replace("'", "''")
      var third = row.Third.Replace("'", "''")

      toinsert.Add(string.Format("( '{0}', '{1}', '{2}' )", first, second, third));
}
if (toinsert.Count != 0)
{
      insertCmd.Append(string.Join(",", toinsert));
      insertCmd.Append(";");
}
using (MySqlCommand myCmd = new MySqlCommand(insertCmd.ToString(), SQLconnectionObject))
{
      myCmd.CommandType = CommandType.Text;
      myCmd.ExecuteNonQuery();
}

*Create SQL connection object and replace it where I have written SQLconnectionObject.

tl;dr

Use either of the Map implementations bundled with Java 6 and later that implement NavigableMap (the successor to SortedMap):

• Use TreeMap if running single-threaded, or if the map is to be read-only across threads after first being populated.
• Use ConcurrentSkipListMap if manipulating the map across threads.

NavigableMap

FYI, the SortedMap interface was succeeded by the NavigableMap interface.

You would only need to use SortedMap if using 3rd-party implementations that have not yet declared their support of NavigableMap. Of the maps bundled with Java, both of the implementations that implement SortedMap also implement NavigableMap.

Interface versus concrete class

s SortedMap the best answer? TreeMap?

As others mentioned, SortedMap is an interface while TreeMap is one of multiple implementations of that interface (and of the more recent NavigableMap.

Having an interface allows you to write code that uses the map without breaking if you later decide to switch between implementations.

NavigableMap< Employee , Project > currentAssignments = new TreeSet<>() ;
currentAssignments.put( alice , writeAdCopyProject ) ; 
currentAssignments.put( bob , setUpNewVendorsProject ) ; 

This code still works if later change implementations. Perhaps you later need a map that supports concurrency for use across threads. Change that declaration to:

NavigableMap< Employee , Project > currentAssignments = new ConcurrentSkipListMap<>() ;

…and the rest of your code using that map continues to work.

Choosing implementation

There are ten implementations of Map bundled with Java 11. And more implementations provided by 3rd parties such as Google Guava.

Here is a graphic table I made highlighting the various features of each. Notice that two of the bundled implementations keep the keys in sorted order by examining the key’s content. Also, EnumMap keeps its keys in the order of the objects defined on that enum. Lastly, the LinkedHashMap remembers original insertion order.

The documentation could help you : http://java.sun.com/j2se/1.5.0/docs/api/javax/xml/parsers/DocumentBuilder.html

The method DocumentBuilder.parse(String) takes a URI and tries to open it. If you want to directly give the content, you have to give it an InputStream or Reader, for example a StringReader. ... Welcome to the Java standard levels of indirections !

Basically :

DocumentBuilder db = ...;
String xml = ...;
db.parse(new InputSource(new StringReader(xml)));

Note that if you read your XML from a file, you can directly give the File object to DocumentBuilder.parse() .

As a side note, this is a pattern you will encounter a lot in Java. Usually, most API work with Streams more than with Strings. Using Streams means that potentially not all the content has to be loaded in memory at the same time, which can be a great idea !

You can also use as many classes as needed on a tag, but an id must be unique to the document. Also be careful of using too many divs, when another more semantic tag can do the job.

<p id="unique" class="x y z">Styled paragraph</p>

I am trying to obtain a handle on one of the views in the Action Bar

I will assume that you mean something established via android:actionLayout in your <item> element of your <menu> resource.

I have tried calling findViewById(R.id.menu_item)

To retrieve the View associated with your android:actionLayout, call findItem() on the Menu to retrieve the MenuItem, then call getActionView() on the MenuItem. This can be done any time after you have inflated the menu resource.

Use the svn move command to move file/folder.

Set a flag on hover:

var over = false;
$('#elem').hover(function() {
  over = true;
},
function () {
  over = false;
});

Then just check your flag.

The type and definition of foreign key field and reference must be equal. This means your foreign key disallows changing the type of your field.

One solution would be this:

LOCK TABLES 
    favorite_food WRITE,
    person WRITE;

ALTER TABLE favorite_food
    DROP FOREIGN KEY fk_fav_food_person_id,
    MODIFY person_id SMALLINT UNSIGNED;

Now you can change you person_id

ALTER TABLE person MODIFY person_id SMALLINT UNSIGNED AUTO_INCREMENT;

recreate foreign key

ALTER TABLE favorite_food
    ADD CONSTRAINT fk_fav_food_person_id FOREIGN KEY (person_id)
          REFERENCES person (person_id);

UNLOCK TABLES;

EDIT: Added locks above, thanks to comments

You have to disallow writing to the database while you do this, otherwise you risk data integrity problems.

I've added a write lock above

All writing queries in any other session than your own ( INSERT, UPDATE, DELETE ) will wait till timeout or UNLOCK TABLES; is executed

http://dev.mysql.com/doc/refman/5.5/en/lock-tables.html

EDIT 2: OP asked for a more detailed explanation of the line "The type and definition of foreign key field and reference must be equal. This means your foreign key disallows changing the type of your field."

From MySQL 5.5 Reference Manual: FOREIGN KEY Constraints

Corresponding columns in the foreign key and the referenced key must have similar internal data types inside InnoDB so that they can be compared without a type conversion. The size and sign of integer types must be the same. The length of string types need not be the same. For nonbinary (character) string columns, the character set and collation must be the same.

Never ever use for it may cause almost untraceable bugs.

Don't be fooled, this is not about idiomatic code or style issues. Ruby's implementation of for has a serious flaw and should not be used.

Here is an example where for introduces a bug,

class Library
  def initialize
    @ary = []
  end
  def method_with_block(&block)
    @ary << block
  end
  def method_that_uses_these_blocks
    @ary.map(&:call)
  end
end

lib = Library.new

for n in %w{foo bar quz}
  lib.method_with_block { n }
end

puts lib.method_that_uses_these_blocks

Prints

quz
quz
quz

Using %w{foo bar quz}.each { |n| ... } prints

foo
bar
quz

Why?

In a for loop the variable n is defined once and only and then that one definition is use for all iterations. Hence each blocks refer to the same n which has a value of quz by the time the loop ends. Bug!

In an each loop a fresh variable n is defined for each iteration, for example above the variable n is defined three separate times. Hence each block refer to a separate n with the correct values.

Use the change event of the select:

$('#my_select').change(function()
{
   $(this).parents('td').css('background', '#000000');
});

Each thread in a Java application has its own stack. The stack is used to hold return addresses, function/method call arguments, etc. So if a thread tends to process large structures via recursive algorithms, it may need a large stack for all those return addresses and such. With the Sun JVM, you can set that size via that parameter.

You can create a linked server and reference the table in the other instance using its fully qualified Server.Catalog.Schema.Table name.

Use %in% as follows

A$C %in% B$C

Which will tell you which values of column C of A are in B.

What is returned is a logical vector. In the specific case of your example, you get:

A$C %in% B$C
# [1]  TRUE FALSE  TRUE  TRUE

Which you can use as an index to the rows of A or as an index to A$C to get the actual values:

# as a row index
A[A$C %in% B$C,  ]  # note the comma to indicate we are indexing rows

# as an index to A$C
A$C[A$C %in% B$C]
[1] 1 3 4  # returns all values of A$C that are in B$C

We can negate it too:

A$C[!A$C %in% B$C]
[1] 2   # returns all values of A$C that are NOT in B$C

  2 %in% B$C   # "is the value 2 in B$C ?"  
  # FALSE

  A$C[2] %in% B$C  # "is the 2nd element of A$C in B$C ?"  
  # FALSE

You can do this by displaying a div (if you want to do it in a modal manner you could use blockUI - or one of the many other modal dialog plugins out there) prior to the request then just waiting until the call back succeeds as a quick example you can you $.getJSON as follows (you might want to use .ajax if you want to add proper error handling)

$("#ajaxLoader").show(); //Or whatever you want to do
$.getJSON("/AJson/Call/ThatTakes/Ages", function(result) {
    //Process your response
    $("#ajaxLoader").hide();
});

If you do this several times in your app and want to centralise the behaviour for all ajax calls you can make use of the global AJAX events:-

$("#ajaxLoader").ajaxStart(function() { $(this).show(); })
               .ajaxStop(function() { $(this).hide(); });

Using blockUI is similar for example with mark up like:-

<a href="/Path/ToYourJson/Action" id="jsonLink">Get JSON</a>
<div id="resultContainer" style="display:none">
And the answer is:-
    <p id="result"></p>
</div>

<div id="ajaxLoader" style="display:none">
    <h2>Please wait</h2>
    <p>I'm getting my AJAX on!</p>
</div>

And using jQuery:-

$(function() {
    $("#jsonLink").click(function(e) {
        $.post(this.href, function(result) {
            $("#resultContainer").fadeIn();
            $("#result").text(result.Answer);
        }, "json");
        return false;
    });
    $("#ajaxLoader").ajaxStart(function() {
                          $.blockUI({ message: $("#ajaxLoader") });
                     })
                    .ajaxStop(function() { 
                          $.unblockUI();
                     });
});

You can try this

 $('div.easy_editor').css({'border-width':'9px', 'border-style':'solid', 'border-color':'red'});

The $('div.easy_editor') refers to a collection of all divs that have the class easy editor already. There is no need to use each() unless there was some function that you wanted to run on each. The css() method actually applies to all the divs you find.

Should you want to clear the array with something other than a value, std::file wont cut it; instead I found std::generate useful. e.g. I had a vector of lists I wanted to initialize

std::generate(v.begin(), v.end(), [] () { return std::list<X>(); });

You can do ints too e.g.

std::generate(v.begin(), v.end(), [n = 0] () mutable { return n++; });

or just

std::generate(v.begin(), v.end(), [] (){ return 0; });

but I imagine std::fill is faster for the simplest case

this code if u make a register form with textBox and use insert and ur textBox is empty and u click on submit button .

CREATE UNIQUE NONCLUSTERED INDEX [IX_tableName_Column]
ON [dbo].[tableName]([columnName] ASC) WHERE [columnName] !=`''`;

If you want it to be List<string>, get rid of the anonymous type and add a .ToList() call:

List<string> list = (from char c in source
                     select c.ToString()).ToList();

I think you would like to learn ajax first, try this: Ajax Tutorial

If you want to know how ajax works, it is not a good way to use jQuery directly. I support to learn the native way to send a ajax request to the server, see something about XMLHttpRequest:

var xhr = new XMLHttpReuqest();
xhr.open("GET", "http://some.com");

xhr.onreadystatechange = handler; // do something here...
xhr.send();

Try initializing with null value.

private java.util.Date date2 = null;

Also private java.util.Date date2 = ""; will not work as "" is a string.

You can hide it :

html {
  overflow:   scroll;
}
::-webkit-scrollbar {
    width: 0px;
    background: transparent; /* make scrollbar transparent */
}

For further information, see : Hide scroll bar, but while still being able to scroll

Rajesh's suggestion did not work for me. What I did was go to

File -> Settings ->HTTP Proxy(Under IDE Settings) ->Manual proxy configuration

I still left the proxy information in Project Settings under Gradle, like Rajesh suggested. But I'm not entirely sure if it's necessary.

I am using 0.8.6 Beta

Python 3.10 (use |): Example for a function which takes a single argument that is either an int or str and returns either an int or str:

def func(arg: int | str) -> int | str:
              ^^^^^^^^^     ^^^^^^^^^ 
             type of arg   return type

Python 3.5 - 3.9 (use typing.Union):

from typing import Union
def func(arg: Union[int, str]) -> Union[int, str]:
              ^^^^^^^^^^^^^^^     ^^^^^^^^^^^^^^^ 
                type of arg         return type

For the special case of X | None you can use Optional[X].

You had thead in your selector, but there is no thead in your table. Also you had your selectors backwards. As you mentioned above, you wanted to be adding the tr class to the th, not vice-versa (although your comment seems to contradict what you wrote up above).

$('tr th').each(function(index){     if($('tr td').eq(index).attr('class') != ''){         // get the class of the td         var tdClass = $('tr td').eq(index).attr('class');         // add it to this th         $(this).addClass(tdClass );     } }); 

Fiddle

While a comprehensive answer to this question takes up hundreds of pages of my book, here's a quick comparison chart that I'm still working on:

The accepted answer wasn't working for me when trying to parse the registry for uninstall strings, and execute them. Turns out I didn't need the call to Invoke-Expression after all.

I finally came across this nice template for seeing how to execute uninstall strings:

$path = 'HKLM:\SOFTWARE\Wow6432Node\Microsoft\Windows\CurrentVersion\Uninstall'
$app = 'MyApp'
$apps= @{}
Get-ChildItem $path | 
    Where-Object -FilterScript {$_.getvalue('DisplayName') -like $app} | 
    ForEach-Object -process {$apps.Set_Item(
        $_.getvalue('UninstallString'),
        $_.getvalue('DisplayName'))
    }

foreach ($uninstall_string in $apps.GetEnumerator()) {
    $uninstall_app, $uninstall_arg = $uninstall_string.name.split(' ')
    & $uninstall_app $uninstall_arg
}

This works for me, namely because $app is an in house application that I know will only have two arguments. For more complex uninstall strings you may want to use the join operator. Also, I just used a hash-map, but really, you'd probably want to use an array.

Also, if you do have multiple versions of the same application installed, this uninstaller will cycle through them all at once, which confuses MsiExec.exe, so there's that too.

With scroll always being shown, maybe be not good for layout.

Try to limit body width with css3

body {
    width: calc(100vw - 34px);
}

vw is the width of the viewport (see this link for some explanation)
calc calculate in css3
34px stands for double scrollbar width (see this for fixed or this to calculate if you don't trust fixed sizes)

Right click on the project in solution explorer or class view window --> "View" --> "View Class Diagram"

By referring this(http://www.excelforum.com/excel-programming-vba-macros/867665-application-cutcopymode-false.html) link the answer is as below:

Application.CutCopyMode=False is seen in macro recorder-generated code when you do a copy/cut cells and paste . The macro recorder does the copy/cut and paste in separate statements and uses the clipboard as an intermediate buffer. I think Application.CutCopyMode = False clears the clipboard. Without that line you will get the warning 'There is a large amount of information on the Clipboard....' when you close the workbook with a large amount of data on the clipboard.

With optimised VBA code you can usually do the copy/cut and paste operations in one statement, so the clipboard isn't used and Application.CutCopyMode = False isn't needed and you won't get the warning.

Use:

$facebook->api('/'.$facebook_uid)

instead of

$facebook->api('/me')

it works.

All these answers are nice however when thinking about it....
Sometimes the most simple approach without sophistication will do the trick quicker and with no special functions.

We first set the arrays:

$arr1 = Array(
"cod" => ddd,
"denum" => ffffffffffffffff,
"descr" => ggggggg,
"cant" => 3
);
$arr2 = Array
(
"cod" => fff,
"denum" => dfgdfgdfgdfgdfg,
"descr" => dfgdfgdfgdfgdfg,
"cant" => 33
);

Then we add them to the new array :

$newArr[] = $arr1;
$newArr[] = $arr2;

Now lets see our new array with all the keys:

print_r($newArr);

There's no need for sql or special functions to build a new multi-dimensional array.... don't use a tank to get to where you can walk.

I couldn't get the 'require' error to go away by using any of the tricks above.

But I found out that the issue was that my TypeScript tools for Visual Studio where an old version (1.8.6.0) and the latest version as of today is (2.0.6.0).

You can download the latest version of the tools from:

1 - right click the highlight whose color you want to change

2 - select "Properties" in the popup menu

3 - choose the new color (as coobird suggested)

This solution is easy because you dont have to search for the highlight by its name ("Ocurrence" or "Write Ocurrence" etc), just right click and the appropriate window is shown.

Stackoverflow uses such function to determine the age of a user.

Calculate age in C#

The given answer is

DateTime now = DateTime.Today;
int age = now.Year - bday.Year;
if (now < bday.AddYears(age)) age--;

So your helper method would look like

public static string Age(this HtmlHelper helper, DateTime birthday)
{
    DateTime now = DateTime.Today;
    int age = now.Year - birthday.Year;
    if (now < birthday.AddYears(age)) age--;

    return age.ToString();
}

Today, I use a different version of this function to include a date of reference. This allow me to get the age of someone at a future date or in the past. This is used for our reservation system, where the age in the future is needed.

public static int GetAge(DateTime reference, DateTime birthday)
{
    int age = reference.Year - birthday.Year;
    if (reference < birthday.AddYears(age)) age--;

    return age;
}

SELECT users.id, DATE_FORMAT(users.signup_date, '%Y-%m-%d')

Best way to check if a list is empty

For example, if passed the following:

a = []

How do I check to see if a is empty?

Short Answer:

Place the list in a boolean context (for example, with an if or while statement). It will test False if it is empty, and True otherwise. For example:

if not a:                           # do this!
    print('a is an empty list')

PEP 8

PEP 8, the official Python style guide for Python code in Python's standard library, asserts:

For sequences, (strings, lists, tuples), use the fact that empty sequences are false.

Yes: if not seq:
     if seq:

No: if len(seq):
    if not len(seq):

We should expect that standard library code should be as performant and correct as possible. But why is that the case, and why do we need this guidance?

Explanation

I frequently see code like this from experienced programmers new to Python:

if len(a) == 0:                     # Don't do this!
    print('a is an empty list')

And users of lazy languages may be tempted to do this:

if a == []:                         # Don't do this!
    print('a is an empty list')

These are correct in their respective other languages. And this is even semantically correct in Python.

But we consider it un-Pythonic because Python supports these semantics directly in the list object's interface via boolean coercion.

From the docs (and note specifically the inclusion of the empty list, []):

By default, an object is considered true unless its class defines either a __bool__() method that returns False or a __len__() method that returns zero, when called with the object. Here are most of the built-in objects considered false:

• constants defined to be false: None and False.
• zero of any numeric type: 0, 0.0, 0j, Decimal(0), Fraction(0, 1)
• empty sequences and collections: '', (), [], {}, set(), range(0)

And the datamodel documentation:

object.__bool__(self)

Called to implement truth value testing and the built-in operation bool(); should return False or True. When this method is not defined, __len__() is called, if it is defined, and the object is considered true if its result is nonzero. If a class defines neither __len__() nor __bool__(), all its instances are considered true.

and

object.__len__(self)

Called to implement the built-in function len(). Should return the length of the object, an integer >= 0. Also, an object that doesn’t define a __bool__() method and whose __len__() method returns zero is considered to be false in a Boolean context.

So instead of this:

if len(a) == 0:                     # Don't do this!
    print('a is an empty list')

or this:

if a == []:                     # Don't do this!
    print('a is an empty list')

Do this:

if not a:
    print('a is an empty list')

Doing what's Pythonic usually pays off in performance:

Does it pay off? (Note that less time to perform an equivalent operation is better:)

>>> import timeit
>>> min(timeit.repeat(lambda: len([]) == 0, repeat=100))
0.13775854044661884
>>> min(timeit.repeat(lambda: [] == [], repeat=100))
0.0984637276455409
>>> min(timeit.repeat(lambda: not [], repeat=100))
0.07878462291455435

For scale, here's the cost of calling the function and constructing and returning an empty list, which you might subtract from the costs of the emptiness checks used above:

>>> min(timeit.repeat(lambda: [], repeat=100))
0.07074015751817342

We see that either checking for length with the builtin function len compared to 0 or checking against an empty list is much less performant than using the builtin syntax of the language as documented.

Why?

For the len(a) == 0 check:

First Python has to check the globals to see if len is shadowed.

Then it must call the function, load 0, and do the equality comparison in Python (instead of with C):

>>> import dis
>>> dis.dis(lambda: len([]) == 0)
  1           0 LOAD_GLOBAL              0 (len)
              2 BUILD_LIST               0
              4 CALL_FUNCTION            1
              6 LOAD_CONST               1 (0)
              8 COMPARE_OP               2 (==)
             10 RETURN_VALUE

And for the [] == [] it has to build an unnecessary list and then, again, do the comparison operation in Python's virtual machine (as opposed to C)

>>> dis.dis(lambda: [] == [])
  1           0 BUILD_LIST               0
              2 BUILD_LIST               0
              4 COMPARE_OP               2 (==)
              6 RETURN_VALUE

The "Pythonic" way is a much simpler and faster check since the length of the list is cached in the object instance header:

>>> dis.dis(lambda: not [])
  1           0 BUILD_LIST               0
              2 UNARY_NOT
              4 RETURN_VALUE

Evidence from the C source and documentation

PyVarObject

This is an extension of PyObject that adds the ob_size field. This is only used for objects that have some notion of length. This type does not often appear in the Python/C API. It corresponds to the fields defined by the expansion of the PyObject_VAR_HEAD macro.

From the c source in Include/listobject.h:

typedef struct {
    PyObject_VAR_HEAD
    /* Vector of pointers to list elements.  list[0] is ob_item[0], etc. */
    PyObject **ob_item;

    /* ob_item contains space for 'allocated' elements.  The number
     * currently in use is ob_size.
     * Invariants:
     *     0 <= ob_size <= allocated
     *     len(list) == ob_size

Response to comments:

I would point out that this is also true for the non-empty case though its pretty ugly as with l=[] then %timeit len(l) != 0 90.6 ns ± 8.3 ns, %timeit l != [] 55.6 ns ± 3.09, %timeit not not l 38.5 ns ± 0.372. But there is no way anyone is going to enjoy not not l despite triple the speed. It looks ridiculous. But the speed wins out
I suppose the problem is testing with timeit since just if l: is sufficient but surprisingly %timeit bool(l) yields 101 ns ± 2.64 ns. Interesting there is no way to coerce to bool without this penalty. %timeit l is useless since no conversion would occur.

IPython magic, %timeit, is not entirely useless here:

In [1]: l = []                                                                  

In [2]: %timeit l                                                               
20 ns ± 0.155 ns per loop (mean ± std. dev. of 7 runs, 100000000 loops each)

In [3]: %timeit not l                                                           
24.4 ns ± 1.58 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

In [4]: %timeit not not l                                                       
30.1 ns ± 2.16 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

We can see there's a bit of linear cost for each additional not here. We want to see the costs, ceteris paribus, that is, all else equal - where all else is minimized as far as possible:

In [5]: %timeit if l: pass                                                      
22.6 ns ± 0.963 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

In [6]: %timeit if not l: pass                                                  
24.4 ns ± 0.796 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

In [7]: %timeit if not not l: pass                                              
23.4 ns ± 0.793 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

Now let's look at the case for an unempty list:

In [8]: l = [1]                                                                 

In [9]: %timeit if l: pass                                                      
23.7 ns ± 1.06 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

In [10]: %timeit if not l: pass                                                 
23.6 ns ± 1.64 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

In [11]: %timeit if not not l: pass                                             
26.3 ns ± 1 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

What we can see here is that it makes little difference whether you pass in an actual bool to the condition check or the list itself, and if anything, giving the list, as is, is faster.

Python is written in C; it uses its logic at the C level. Anything you write in Python will be slower. And it will likely be orders of magnitude slower unless you're using the mechanisms built into Python directly.

No net restart, unfortunately.

Look for books by Ted Padova. Over the years, he has written a series of books called The Acrobat PDF {5,6,7,8,9...} Bible. They contain chapter(s) on JavaScript in PDF files. They are not as comprehensive as the reference documentation listed here, but in the books there are some realistic use-cases discussed in context.

There was also a talk on hacking PDF files by a computer scientist, given at a conference in 2010. The link on the talk's announcement-page to the slides is dead, but Google is your friend-. The talk is not exclusively on JavaScript, though. YouTube video - JavaScript starts at 06:00.

Here's a function I wrote which works similarly to the Unix time command:

function time {
    Param(
        [Parameter(Mandatory=$true)]
        [string]$command,
        [switch]$quiet = $false
    )
    $start = Get-Date
    try {
        if ( -not $quiet ) {
            iex $command | Write-Host
        } else {
            iex $command > $null
        }
    } finally {
        $(Get-Date) - $start
    }
}

You can use wait:

some_command &
P1=$!
other_command &
P2=$!
wait $P1 $P2

It assigns the background program PIDs to variables ($! is the last launched process' PID), then the wait command waits for them. It is nice because if you kill the script, it kills the processes too!

Step 1: Open an elevated Task Scheduler (ie. right-click on the Task Scheduler icon and choose Run as administrator)

Step 2: In the Actions pane (right pane, not the actions tab), click Enable All Tasks History

That's it. Not sure why this isn't on by default, but it isn't.

While I like the class decorator from Oz123, you could also do the following, which uses an explicit class wrapper and __new__ with a class Factory method returning the class within a closure:

class B(object):
    def __new__(cls, val):
        return cls.factory(val)

@classmethod
def factory(cls, val):
    private = {'var': 'test'}

    class InnerB(object):
        def __init__(self):
            self.variable = val
            pass

        @property
        def var(self):
            return private['var']

    return InnerB()

Yes, this is documented in RFC 3986, section 5.2:

(edit: Oops, my RFC reference was outdated).

A simple one would be

\d{4}-\d{2}-\d{2}

Debuggex Demo

but this does not restrict month to 1-12 and days from 1 to 31.

There are more complex checks like in the other answers, by the way pretty clever ones. Nevertheless you have to check for a valid date, because there are no checks for if a month has 28, 30, or 31 days.

Alternative way: use the command interface!

Cmd/Ctrl + Shift + P ? Python: Select Interpreter ? choose the one with the packages you look for:

Strictly it should match

[A-Za-z][-A-Za-z0-9_:.]*

But jquery seems to have problems with colons so it might be better to avoid them.

First create helpers.php inside App\Http directory. Then add the following code inside the composer.json

"autoload": {
        "classmap": [
            "database"
        ],
        "files": [
            "app/Http/helpers.php"
        ],
        "psr-4": {
            "App\\": "app/"
        }
    },

Next run the following command

composer dump-autoload

Now you can define your custom function inside the helpers.php file.

Here is another easy way:

1. use DB1; show create table TB1;
   • copy the syntax here in clipboard to create TB1 in DB2
2. use DB2;
   • paste the syntax here to create the table TB1

INSERT INTO DB2.TB1 SELECT * from DB1.TB1;

Please remove e.preventDefault(), because event.cancelable of touchmove is false. So you can't call this method.

If you want a cross-platform method of doing this, the general pattern is to derive from QThread and create a function (static, if you'd like) in your derived class that will call one of the sleep functions in QThread.

Same problem happened with me . I started eclipse after many days , but it was not starting.just eclipse window flashing , no error nothing. After many trials , i just re-installed my jdk . It worked for me, i think some of my java files were missing or damaged . Try by reinstalling your jdk version it may work as it worked for me.

The posted solutions will not link any hidden files. To include them, try this:

cd /usr/lib
find /mnt/usr/lib -maxdepth 1 -print "%P\n" | while read file; do ln -s "/mnt/usr/lib/$file" "$file"; done

If you should happen to want to recursively create the directories and only link files (so that if you create a file within a directory, it really is in /usr/lib not /mnt/usr/lib), you could do this:

cd /usr/lib
find /mnt/usr/lib -mindepth 1 -depth -type d -printf "%P\n" | while read dir; do mkdir -p "$dir"; done
find /mnt/usr/lib -type f -printf "%P\n" | while read file; do ln -s "/mnt/usr/lib/$file" "$file"; done

there you go

$date = "04-15-2013";
$date1 = str_replace('-', '/', $date);
$tomorrow = date('m-d-Y',strtotime($date1 . "+1 days"));

echo $tomorrow;

this will output

04-16-2013

Documentation for both function
date
strtotime

Try this:

if(Math.floor(id) == id && $.isNumeric(id)) 
  alert('yes its an int!');

$.isNumeric(id) checks whether it's numeric or not
Math.floor(id) == id will then determine if it's really in integer value and not a float. If it's a float parsing it to int will give a different result than the original value. If it's int both will be the same.

this will return first match

@fathers.detect {|f| f["age"] > 35 }

Rather than creating empty directories in source to exclude, you can supply the full destination path to the /XD switch to have the destination directories untouched

robocopy "%SOURCE_PATH%" "%DEST_PATH%" /MIR /XD "%DEST_PATH%"\hq04s2dba301

Here's the most straightforward way to create a drawing application with canvas:

1. Attach a mousedown, mousemove, and mouseup event listener to the canvas DOM
2. on mousedown, get the mouse coordinates, and use the moveTo() method to position your drawing cursor and the beginPath() method to begin a new drawing path.
3. on mousemove, continuously add a new point to the path with lineTo(), and color the last segment with stroke().
4. on mouseup, set a flag to disable the drawing.

From there, you can add all kinds of other features like giving the user the ability to choose a line thickness, color, brush strokes, and even layers.

You can implement this way

$resource('http://localhost\\:3000/realmen/:entryId', {entryId: '@entryId'}, {
        UPDATE: {method: 'PUT', url: 'http://localhost\\:3000/realmen/:entryId' },
        ACTION: {method: 'PUT', url: 'http://localhost\\:3000/realmen/:entryId/action' }
    })

RealMen.query() //GET  /realmen/
RealMen.save({entryId: 1},{post data}) // POST /realmen/1
RealMen.delete({entryId: 1}) //DELETE /realmen/1

//any optional method
RealMen.UPDATE({entryId:1}, {post data}) // PUT /realmen/1

//query string
RealMen.query({name:'john'}) //GET /realmen?name=john

Hope it helps

Look here http://docs.oracle.com/javase/6/docs/api/java/awt/Font.html#deriveFont%28float%29

JComponent has a setFont() method. You will control the font there, not on the String.

Such as

JButton b = new JButton();
b.setFont(b.getFont().deriveFont(18.0f));

Did you include "bootstrap-theme.css" files on your code?

In "bootstrap-theme.min.css" files, background-image about ".active" is existed for "navbar" (check this screenshot: http://i.imgur.com/1etLIyY.png).

It will re-declare your style code, and then it will be effected on your code.

So after you delete or re-declare them (background-image), you can use your background color style about the ".active" tag.

I have catched the same exception and found a InnerException: SocketException. in the svclog trace.

After looking in the windows event log I saw an error coming from the System.ServiceModel.Activation.TcpWorkerProcess class.

Are you hosting your wcf service in IIS with netTcpBinding and port sharing?

It seems there is a bug in IIS port sharing feature, check the fix:

My solution is to host your WCF service in a Windows Service.

I had the same error message and after lots of trial and error found out that it was caused by an advanced filter which was set on the ListObject. After clearing the advanced filter .listrows.add worked fine again. To clear the filter I use this - no idea how one could clear the filter only for the specific listobject instead of the complete worksheet.

Worksheets("mysheet").ShowAllData

If you have it, try removing this from your vimrc: set mouse=a

It messes with the paste functionality.

there is server issue pick gmt+0000 standard time zone you can change it by using library moment-timezone in javascript

const moment = require("moment-timezone")
const dateNew = new Date()
const changeZone = moment(dateNew);
changeZone.tz("Asia/Karachi").format("ha z");
// here you can paste "your time zone string"

This is the solution I came up with:

import time
from threading import Thread
from threading import Lock

def myfunc(i, mutex):
    mutex.acquire(1)
    time.sleep(1)
    print "Thread: %d" %i
    mutex.release()


mutex = Lock()
for i in range(0,10):
    t = Thread(target=myfunc, args=(i,mutex))
    t.start()
    print "main loop %d" %i

Output:

#use return convertView;

Code:

public View getView(final int position, View convertView, ViewGroup parent) {

    //convertView = null;

    if (convertView == null) {

        LayoutInflater mInflater = (LayoutInflater) context.getSystemService(Activity.LAYOUT_INFLATER_SERVICE);
        convertView = mInflater.inflate(R.layout.list_item, null);

In general you can concatenate a whole sequence of arrays along any axis:

numpy.concatenate( LIST, axis=0 )

but you do have to worry about the shape and dimensionality of each array in the list (for a 2-dimensional 3x5 output, you need to ensure that they are all 2-dimensional n-by-5 arrays already). If you want to concatenate 1-dimensional arrays as the rows of a 2-dimensional output, you need to expand their dimensionality.

As Jorge's answer points out, there is also the function stack, introduced in numpy 1.10:

numpy.stack( LIST, axis=0 )

This takes the complementary approach: it creates a new view of each input array and adds an extra dimension (in this case, on the left, so each n-element 1D array becomes a 1-by-n 2D array) before concatenating. It will only work if all the input arrays have the same shape—even along the axis of concatenation.

vstack (or equivalently row_stack) is often an easier-to-use solution because it will take a sequence of 1- and/or 2-dimensional arrays and expand the dimensionality automatically where necessary and only where necessary, before concatenating the whole list together. Where a new dimension is required, it is added on the left. Again, you can concatenate a whole list at once without needing to iterate:

numpy.vstack( LIST )

This flexible behavior is also exhibited by the syntactic shortcut numpy.r_[ array1, ...., arrayN ] (note the square brackets). This is good for concatenating a few explicitly-named arrays but is no good for your situation because this syntax will not accept a sequence of arrays, like your LIST.

There is also an analogous function column_stack and shortcut c_[...], for horizontal (column-wise) stacking, as well as an almost-analogous function hstack—although for some reason the latter is less flexible (it is stricter about input arrays' dimensionality, and tries to concatenate 1-D arrays end-to-end instead of treating them as columns).

Finally, in the specific case of vertical stacking of 1-D arrays, the following also works:

numpy.array( LIST )

...because arrays can be constructed out of a sequence of other arrays, adding a new dimension to the beginning.

If you're using old, C-style string instead of the newer, STL-style strings, there's the strlen function in the C run time library:

const char* p = "Hello";
size_t n = strlen(p);

try this

public static string cleanPhone(string inVal)
        {
            char[] newPhon = new char[inVal.Length];
            int i = 0;
            foreach (char c in inVal)
                if (c.CompareTo('0') > 0 && c.CompareTo('9') < 0)
                    newPhon[i++] = c;
            return newPhon.ToString();
        }

When you create a new CMS block named block_identifier from the admin panel you can use the following code to call it from your .phtml file:

<?php echo $this->getLayout()->createBlock('cms/block')->setBlockId('block_identifier')->toHtml(); 
?> 

Then clear the cache and reload your browser.

SimpleDateFormat simpleDateFormat = new SimpleDateFormat("HH:MM");
simpleDateFormat.format(fajr_prayertime);

For a use case like this, it may be useful to use a string constant so it can be marshaled into a JSON string. In the following example, []Base{A,C,G,T} would get marshaled to ["adenine","cytosine","guanine","thymine"].

type Base string

const (
    A Base = "adenine"
    C      = "cytosine"
    G      = "guanine"
    T      = "thymine"
)

When using iota, the values get marshaled into integers. In the following example, []Base{A,C,G,T} would get marshaled to [0,1,2,3].

type Base int

const (
    A Base = iota
    C
    G
    T
)

Here's an example comparing both approaches:

I wanted to answer to the following question which is a little bit different than this:

Best way to print messages on multiple lines

He wanted to show lines from repeated characters too. He wanted this output:

----------------------------------------
# Operator Micro-benchmarks
# Run_mode: short
# Num_repeats: 5
# Num_runs: 1000

----------------------------------------

You can create those lines inside f-strings with a multiplication, like this:

run_mode, num_repeats, num_runs = 'short', 5, 1000

s = f"""
{'-'*40}
# Operator Micro-benchmarks
# Run_mode: {run_mode}
# Num_repeats: {num_repeats}
# Num_runs: {num_runs}

{'-'*40}
"""

print(s)

Using column name worked for me.

sorted_df = df.sort_values(by=['Column_name'], ascending=True)

Using anytime package:

library(anytime)

anydate("2009-01")
# [1] "2009-01-01"

in public static void main(String args[]) args is an array of console line argument whose data type is String. in this array, you can store various string arguments by invoking them at the command line as shown below: java myProgram Shaan Royal then Shaan and Royal will be stored in the array as arg[0]="Shaan"; arg[1]="Royal"; you can do this manually also inside the program, when you don't call them at the command line.

I think the advantages are:

1. Web development in a dynamic language (JavaScript) on a VM that is incredibly fast (V8). It is much faster than Ruby, Python, or Perl.

2. Ability to handle thousands of concurrent connections with minimal overhead on a single process.

3. JavaScript is perfect for event loops with first class function objects and closures. People already know how to use it this way having used it in the browser to respond to user initiated events.

4. A lot of people already know JavaScript, even people who do not claim to be programmers. It is arguably the most popular programming language.

5. Using JavaScript on a web server as well as the browser reduces the impedance mismatch between the two programming environments which can communicate data structures via JSON that work the same on both sides of the equation. Duplicate form validation code can be shared between server and client, etc.

Both functions use the os.path.split(path) function to split the pathname path into a pair; (head, tail).

The os.path.dirname(path) function returns the head of the path.

E.g.: The dirname of '/foo/bar/item' is '/foo/bar'.

The os.path.basename(path) function returns the tail of the path.

E.g.: The basename of '/foo/bar/item' returns 'item'

From: http://docs.python.org/2/library/os.path.html#os.path.basename

You can use the Java enum TimeUnit to perform your math and avoid any hard coded values. Then we can use String.format(String, Object...) and a pair of StringBuilder(s) as well as a DecimalFormat to build the requested output. Something like,

Scanner scanner = new Scanner(System.in);
System.out.println("Please enter a number of seconds:");
String str = scanner.nextLine().replace("\\,", "").trim();
long secondsIn = Long.parseLong(str);
long dayCount = TimeUnit.SECONDS.toDays(secondsIn);
long secondsCount = secondsIn - TimeUnit.DAYS.toSeconds(dayCount);
long hourCount = TimeUnit.SECONDS.toHours(secondsCount);
secondsCount -= TimeUnit.HOURS.toSeconds(hourCount);
long minutesCount = TimeUnit.SECONDS.toMinutes(secondsCount);
secondsCount -= TimeUnit.MINUTES.toSeconds(minutesCount);
StringBuilder sb = new StringBuilder();
sb.append(String.format("%d %s, ", dayCount, (dayCount == 1) ? "day"
        : "days"));
StringBuilder sb2 = new StringBuilder();
sb2.append(sb.toString());
sb2.append(String.format("%02d:%02d:%02d %s", hourCount, minutesCount,
        secondsCount, (hourCount == 1) ? "hour" : "hours"));
sb.append(String.format("%d %s, ", hourCount, (hourCount == 1) ? "hour"
        : "hours"));
sb.append(String.format("%d %s and ", minutesCount,
        (minutesCount == 1) ? "minute" : "minutes"));
sb.append(String.format("%d %s.", secondsCount,
        (secondsCount == 1) ? "second" : "seconds"));
System.out.printf("You entered %s seconds, which is %s (%s)%n",
        new DecimalFormat("#,###").format(secondsIn), sb, sb2);

Which, when I enter 500000 outputs the requested (manual line break added for post) -

You entered 500,000 seconds, which is 5 days, 18 hours, 
53 minutes and 20 seconds. (5 days, 18:53:20 hours)

If you want that warm and fuzzy feeling just go with with.

For python 3.6 I ran these two programs under a fresh start of IDLE, giving runtimes of:

0.002000093460083008  Test A
0.0020003318786621094 Test B: with guaranteed close

So not much of a difference.

You can use this code:

var vid = document.getElementById("video1");

function slowPlaySpeed() { 
    vid.playbackRate = 0.5;
} 

function normalPlaySpeed() { 
    vid.playbackRate = 1;
} 

function fastPlaySpeed() { 
    vid.playbackRate = 2;
}

Use: location.pathname

alert(location.pathname);

For anybody coming here looking for a getTickCount() implementation for iOS, here is mine after putting various sources together.

Previously I had a bug in this code (I divided by 1000000 first) which was causing some quantisation of the output on my iPhone 6 (perhaps this was not an issue on iPhone 4/etc or I just never noticed it). Note that by not performing that division first, there is some risk of overflow if the numerator of the timebase is quite large. If anybody is curious, there is a link with much more information here: https://stackoverflow.com/a/23378064/588476

In light of that information, maybe it is safer to use Apple's function CACurrentMediaTime!

I also benchmarked the mach_timebase_info call and it takes approximately 19ns on my iPhone 6, so I removed the (not threadsafe) code which was caching the output of that call.

#include <mach/mach.h>
#include <mach/mach_time.h>

uint64_t getTickCount(void)
{
    mach_timebase_info_data_t sTimebaseInfo;
    uint64_t machTime = mach_absolute_time();

    // Convert to milliseconds
    mach_timebase_info(&sTimebaseInfo);
    machTime *= sTimebaseInfo.numer;
    machTime /= sTimebaseInfo.denom;
    machTime /= 1000000; // convert from nanoseconds to milliseconds

    return machTime;
}

Do be aware of the potential risk of overflow depending on the output of the timebase call. I suspect (but do not know) that it might be a constant for each model of iPhone. on my iPhone 6 it was 125/3.

The solution using CACurrentMediaTime() is quite trivial:

uint64_t getTickCount(void)
{
    double ret = CACurrentMediaTime();
    return ret * 1000;
}

On Itellij 15 CE, it's enough to just install Lombok Plugin (no additional configuration required).

After many months, I returned to develop an AngularJS (1.6.4) app, for which I chose Chrome (PC) and Safari (MAC) for testing during development. This code presented this Error: $injector:modulerr Module Error on IE 11.0.9600 (Windows 7, 32-bit).

Upon investigation, it became clear that error was due to forEach loop being used, just replaced all the forEach loops with normal for loops for things to work as-is...

It was basically an IE11 issue (answered here) rather than an AngularJS issue, but I want to put this reply here because the exception raised was an AngularJS exception. Hope it would help some of us out there.

similarly. don't use lambda functions... just replace ()=>{...} with good ol' function(){...}

Can't comment because I don't have enough reputation points, but recode only works on a vector, so the above code in @Stefano's answer should be

df <- iris %>%
  mutate(Species = recode(Species, 
     setosa = "SETOSA",
     versicolor = "VERSICOLOR",
     virginica = "VIRGINICA")
  )

If both "document.ready" variants are used they will both fire, in the order of appearance

$(function(){
    alert('shorthand document.ready');
});

//try changing places
$(document).ready(function(){
    alert('document.ready');
});

You may use java.util.Date class and then use SimpleDateFormat to format the Date.

Date date=new Date(millis);

We can use java.time package (tutorial) - DateTime APIs introduced in the Java SE 8.

var instance = java.time.Instant.ofEpochMilli(millis);
var localDateTime = java.time.LocalDateTime
                        .ofInstant(instance, java.time.ZoneId.of("Asia/Kolkata"));
var zonedDateTime = java.time.ZonedDateTime
                            .ofInstant(instance,java.time.ZoneId.of("Asia/Kolkata"));

// Format the date

var formatter = java.time.format.DateTimeFormatter.ofPattern("u-M-d hh:mm:ss a O");
var string = zonedDateTime.format(formatter);

Add bellow line in build.gradle:

compile 'com.commit451:PhotoView:1.2.4'

or

compile 'com.github.chrisbanes:PhotoView:1.3.0'

In Java file:

PhotoViewAttacher photoAttacher;
photoAttacher= new PhotoViewAttacher(Your_Image_View);
photoAttacher.update();

You could try using "typeid".

This doesn't work for "object" name but YOU know the object name so you'll just have to store it somewhere. The Compiler doesn't care what you namned an object.

Its worth bearing in mind, though, that the output of typeid is a compiler specific thing so even if it produces what you are after on the current platform it may not on another. This may or may not be a problem for you.

The other solution is to create some kind of template wrapper that you store the class name in. Then you need to use partial specialisation to get it to return the correct class name for you. This has the advantage of working compile time but is significantly more complex.

Edit: Being more explicit

template< typename Type > class ClassName
{
public:
    static std::string name()
    {
        return "Unknown";
    }
};

Then for each class somethign liek the following:

template<> class ClassName<MyClass>
{
public:
    static std::string name()
    {
        return "MyClass";
    }
};

Which could even be macro'd as follows:

#define DefineClassName( className ) \
\
template<> class ClassName<className> \
{ \
public: \
    static std::string name() \
    { \
        return #className; \
    } \
}; \

Allowing you to, simply, do

DefineClassName( MyClass );

Finally to Get the class name you'd do the following:

ClassName< MyClass >::name();

Edit2: Elaborating further you'd then need to put this "DefineClassName" macro in each class you make and define a "classname" function that would call the static template function.

Edit3: And thinking about it ... Its obviously bad posting first thing in the morning as you may as well just define a member function "classname()" as follows:

std::string classname()
{
     return "MyClass";
}

which can be macro'd as follows:

DefineClassName( className ) \
std::string classname()  \
{ \
     return #className; \
}

Then you can simply just drop

DefineClassName( MyClass );

into the class as you define it ...

you can just use JSON.stringify to test your Object, like this:

var test = {}_x000D_
if(JSON.stringify(test)[0] === '{') {_x000D_
  console.log('this is a Object')_x000D_
}

The answers using subclasses or categories to allow VCs within UINavigationController and UITabBarController classes work well. Launching a portrait-only modal from a landscape tab bar controller failed. If you need to do this, then use the trick of displaying and hiding a non-animated modal view, but do it in the viewDidAppear method. It didn't work for me in viewDidLoad or viewWillAppear.

Apart from that, the solutions above work fine.

If there are no credentials provided in the request headers, the following is the minimum response required for IE to prompt the user for credentials and resubmit the request.

Response.Clear();
Response.StatusCode = (Int32)HttpStatusCode.Unauthorized;
Response.AddHeader("WWW-Authenticate", "Basic");

Simply use the question mark trick for null checks:

string displayName = Dictionary.FirstOrDefault(x => x.Value.ID == long.Parse(options.ID))?.Value.DisplayName ?? "DEFINE A DEFAULT DISPLAY NAME HERE";

select 'DROP TABLE ' + name from sysobjects
where type = 'U' and sysobjects.name like '%test%'

-- Test is the table name

Create a new vector asset in the drawable folder.

You can import your PNG image as well, and convert the file to SVG online at https://image.online-convert.com/convert-to-svg. The higher the resolution, the better the conversion will be.

Next, create a new vector asset from that SVG file.

This is a sample vector circle image you can use. Copy the code to an xml file in the drawables folder.

ic_check.xml:

Use this image in your button:

<ImageButton
    android:id="@+id/btn_level1"
    android:layout_width="36dp"
    android:layout_height="36dp"
    android:background="@drawable/ic_check"
/>

Your button will be a circle button.

Place the Image in the folder drawable. drawable folder is in res. drawable have 5 variants drawable-hdpi drawable-ldpi drawable-mdpi drawable-xhdpi drawable-xxhdpi

There are many ways to get a path. See CurrentDirrectory mentioned. Also, you can get the full file name of your application by using Assembly.GetExecutingAssembly().Location and then use Path class to get a directory name.

Try setting the system default encoding as utf-8 at the start of the script, so that all strings are encoded using that.

Example -

import sys
reload(sys)
sys.setdefaultencoding('utf-8')

The above should set the default encoding as utf-8 .

If you have Perl installed, you could use ack, available at http://beyondgrep.com/.

The reason you get that is the order of precendence of the operators, and the fact that + is used to both concatenate strings as well as perform numeric addition.

In your case, the concatenation of "question-" and i is happening first giving the string "question=1". Then another string concatenation with "1" giving "question-11".

You just simply need to give the interpreter a hint as to what order of prec endence you want.

divID = "question-" + (i+1);

our project surely is configured as "library" thats why you get the message : "Android library projects cannot be launched."

right-click in your project and select Properties. In the Properties window -> "Android" -> uncheck the option "is Library" and apply -> Click "ok" to close the properties window.

Just add this to your ~/.bash_profile to switch between default keys for github.com

# Git SSH keys swap

alias personal_git="ssh-add -D && ssh-add -K ~/.ssh/id_rsa"

Try this:

$comments_collection = $post->comments()->get()->toArray();

see this can help you

That depends on where exactly the XML file is. Is it in the sources folder (in the "default package" or the "root") or in the same folder as the class?

In for former case, you must use "/file.xml" (note the leading slash) to find the file and it doesn't matter which class you use to try to locate it.

If the XML file is next to some class, SomeClass.class.getResourceAsStream() with just the filename is the way to go.

That is because IIS is automatically running on your machine. IIS occupied both port 80 and 443.

I uninstalled IIS for using Apache httpd.

Lets make it very simple:

Maven Lifecycles: 1. Clean 2. Default (build) 3. Site

Maven Phases of the Default Lifecycle: 1. Validate 2. Compile 3. Test 4. Package 5. Verify 6. Install 7. Deploy

Note: Don't mix or get confused with maven goals with maven lifecycle.

I would recommend writing these helpers using named parameters for the sake of clarity as follows:

@Html.ActionLink(
    linkText: "Details",
    actionName: "Details",
    controllerName: "Product",
    routeValues: new {
        id = item.ID
    },
    htmlAttributes: null
)

Darin's answer works great. It creates a 302 redirect. Here's the code modified so that it creates a permanent 301 redirect:

<%@ Page Language="C#" %>
<script runat="server">
  protected override void OnLoad(EventArgs e)
  {
      Response.RedirectPermanent("new.aspx");
      base.OnLoad(e);
  }
</script>

There is a better and quicker way now (Chrome version 59.x.x.):

Right-click onto the reload-icon (left of the url-field) and you get a drop-down menu, select the third option: 'empty Cache and Hard reload'.

This option is only available when the developer tools are open. (Notice the difference to option 2: 'Hard reload' -cmd-shift-R). No cache emptying here!

This is a great sample:

String base64String = "data:image/png;base64,iVBORw0KGgoAAAANSUhEUgAAAIAAAACACAYAAADDPmHLAA...";
String base64Image = base64String.split(",")[1];
byte[] decodedString = Base64.decode(base64Image, Base64.DEFAULT);
Bitmap decodedByte = BitmapFactory.decodeByteArray(decodedString, 0, decodedString.length);
imageView.setImageBitmap(decodedByte);

Sample found at: https://freakycoder.com/android-notes-44-how-to-convert-base64-string-to-bitmap-53f98d5e57af

This is the only code that worked for me in the past.

We can hide close button on form by setting this.ControlBox=false;

Note that this hides all of those sizing buttons. Not just the X. In some cases that may be fine.

Put this in your code (preferably in a general js functions library):

String.prototype.nl2br = function()
{
    return this.replace(/\n/g, "<br />");
}

Usage:

var myString = "test\ntest2";

myString.nl2br();

creating a string prototype function allows you to use this on any string.

Because i need FetchType to be EAGER, i remove all associations by setting them to (null) and save the object (that remove all association in the database) then delete it!

That add some milliseconds but it's fine for me, if there better way to keep those MS add your comment bellow..

Hope that help someone :)

listOfCatalogIDs =[@[@"id[]=",listOfCatalogIDs] componentsJoinedByString:@""];

Yes. Take a look at this other thread for details: How to apply CSS to iframe?

var cssLink = document.createElement("link");
cssLink.href = "style.css";  
cssLink.rel = "stylesheet";  
cssLink.type = "text/css";  
frames['frame1'].document.body.appendChild(cssLink); 

I used this line to listen for input events from javascript.
It is useful because it listens for text change and text pasted events.

myElement.addEventListener('input', e => { myEvent() });

If you are using linux system then you need to add

using namespace std;

Below headers

If windows then make sure you put headers correctly #include<iostream.h>

#include<string.h>

Refer this it work perfectly.

#include <iostream>
#include <string>

int main ()
{
std::string str="We think in generalities, but we live in details.";
                                       // (quoting Alfred N. Whitehead)

  std::string str2 = str.substr (3,5);     // "think"

   std::size_t pos = str.find("live");      // position of "live" in str

  std::string str3 = str.substr (pos);     
// get from "live" to the end

  std::cout << str2 << ' ' << str3 << '\n';

  return 0;
}

Really simple example.

Here is a really simple, but very effective, example. Once you have the basics down you can easily build off of it.

There are two main parts to using a Cursor Adapter with SQLite:

1. Create a proper Cursor from the Database.

2. Create a custom Cursor Adapter that takes the Cursor data from the database and pairs it with the View you intend to represent the data with.

1. Create a proper Cursor from the Database.

In your Activity:

SQLiteOpenHelper sqLiteOpenHelper = new SQLiteOpenHelper( 
        context, DATABASE_NAME, null, DATABASE_VERSION);

SQLiteDatabase sqLiteDatabase = sqLiteOpenHelper.getReadableDatabase();

String query = "SELECT * FROM clients ORDER BY company_name ASC"; // No trailing ';'

Cursor cursor = sqLiteDatabase.rawQuery(query, null); 

ClientCursorAdapter adapter = new ClientCursorAdapter(
        this, R.layout.clients_listview_row, cursor, 0 );

this.setListAdapter(adapter);

2. Create a Custom Cursor Adapter.

Note: Extending from ResourceCursorAdapter assumes you use XML to create your views.

public class ClientCursorAdapter extends ResourceCursorAdapter {

    public ClientCursorAdapter(Context context, int layout, Cursor cursor, int flags) {
        super(context, layout, cursor, flags);
    }

    @Override
    public void bindView(View view, Context context, Cursor cursor) {
        TextView name = (TextView) view.findViewById(R.id.name);
        name.setText(cursor.getString(cursor.getColumnIndex("name")));

        TextView phone = (TextView) view.findViewById(R.id.phone);
        phone.setText(cursor.getString(cursor.getColumnIndex("phone")));
    }
}

There are times that using OPTION(RECOMPILE) makes sense. In my experience the only time this is a viable option is when you are using dynamic SQL. Before you explore whether this makes sense in your situation I would recommend rebuilding your statistics. This can be done by running the following:

EXEC sp_updatestats

And then recreating your execution plan. This will ensure that when your execution plan is created it will be using the latest information.

Adding OPTION(RECOMPILE) rebuilds the execution plan every time that your query executes. I have never heard that described as creates a new lookup strategy but maybe we are just using different terms for the same thing.

When a stored procedure is created (I suspect you are calling ad-hoc sql from .NET but if you are using a parameterized query then this ends up being a stored proc call) SQL Server attempts to determine the most effective execution plan for this query based on the data in your database and the parameters passed in (parameter sniffing), and then caches this plan. This means that if you create the query where there are 10 records in your database and then execute it when there are 100,000,000 records the cached execution plan may no longer be the most effective.

In summary - I don't see any reason that OPTION(RECOMPILE) would be a benefit here. I suspect you just need to update your statistics and your execution plan. Rebuilding statistics can be an essential part of DBA work depending on your situation. If you are still having problems after updating your stats, I would suggest posting both execution plans.

And to answer your question - yes, I would say it is highly unusual for your best option to be recompiling the execution plan every time you execute the query.

>>> original = [('a', 1), ('b', 2), ('c', 3), ('d', 4)]
>>> tuple([list(tup) for tup in zip(*original)])
(['a', 'b', 'c', 'd'], [1, 2, 3, 4])

Gives a tuple of lists as in the question.

list1, list2 = [list(tup) for tup in zip(*original)]

Unpacks the two lists.

A bootstrap v3 solution (where the events have different names), also using only one jQuery selector (as seen here):

$('.accordion').on('hide.bs.collapse show.bs.collapse', function (n) {
    $(n.target).siblings('.panel-heading').find('i.glyphicon').toggleClass('glyphicon-chevron-down glyphicon-chevron-up');
});

Use Android Studio Image Asset

Go to:

 Project>res --> right click

 new> image asset

Then set:

-Icon type: Launcher Icons
-Asset type: Image
-Path: the/path/to/your/image
-Trim: No
-Padding: 0%
-Shape: None
-Effect: None

Select: Next>Finish.

Now you will have your icon in the correct resolutions.

EDIT: I recommend to use SVG images to create Vector Drawables, and then use them in a canvas to resize them to the correct size or simply change the DP.

You can get the default icons from Google or just create your Own

 Project>res --> right click
 new> vector asset

Then set:

-Asset type: Local file (SVG, PSD)
-Path: the/path/to/your/image
-Size: check Override to keep your aspect ratio.
-Chek enable auto mirroring for RTL Layout.

Select: Next>Finish.

Now you will have your icon and you will be able to change size, color etc.. .

Set the Credentials property before sending the message.

you can try this.I think it will work correctly.

long delta = new Date().getTime() - date.getTime();
const int SECOND = 1;
const int MINUTE = 60 * SECOND;
const int HOUR = 60 * MINUTE;
const int DAY = 24 * HOUR;
const int MONTH = 30 * DAY;

if (delta < 0L)
{
  return "not yet";
}
if (delta < 1L * MINUTE)
{
  return ts.Seconds == 1 ? "one second ago" : ts.Seconds + " seconds ago";
}
if (delta < 2L * MINUTE)
{
  return "a minute ago";
}
if (delta < 45L * MINUTE)
{
  return ts.Minutes + " minutes ago";
}
if (delta < 90L * MINUTE)
{
  return "an hour ago";
}
if (delta < 24L * HOUR)
{
  return ts.Hours + " hours ago";
}
if (delta < 48L * HOUR)
{
  return "yesterday";
}
if (delta < 30L * DAY)
{
  return ts.Days + " days ago";
}
if (delta < 12L * MONTH)
{
  int months = Convert.ToInt32(Math.Floor((double)ts.Days / 30));
  return months <= 1 ? "one month ago" : months + " months ago";
}
else
{
  int years = Convert.ToInt32(Math.Floor((double)ts.Days / 365));
  return years <= 1 ? "one year ago" : years + " years ago";
}

If you are trying to keep a list of lists (similar to python's list.append()) then this might work:

a <- list(1,2,3)
b <- list(4,5,6)
c <- append(list(a), list(b))

> c
[[1]]
[[1]][[1]]
[1] 1

[[1]][[2]]
[1] 2

[[1]][[3]]
[1] 3


[[2]]
[[2]][[1]]
[1] 4

[[2]][[2]]
[1] 5

[[2]][[3]]
[1] 6

A quick note that doing this without further securing your Redis server is not a good idea as it can leave you open to attack. Be sure to also implement AUTH or otherwise secure that. See http://redis.io/topics/security for details.

To access the index in this case you access the name attribute:

In [182]:

df = pd.DataFrame([[1,2,3],[4,5,6]], columns=['a','b','c'])
def rowFunc(row):
    return row['a'] + row['b'] * row['c']

def rowIndex(row):
    return row.name
df['d'] = df.apply(rowFunc, axis=1)
df['rowIndex'] = df.apply(rowIndex, axis=1)
df
Out[182]:
   a  b  c   d  rowIndex
0  1  2  3   7         0
1  4  5  6  34         1

Note that if this is really what you are trying to do that the following works and is much faster:

In [198]:

df['d'] = df['a'] + df['b'] * df['c']
df
Out[198]:
   a  b  c   d
0  1  2  3   7
1  4  5  6  34

In [199]:

%timeit df['a'] + df['b'] * df['c']
%timeit df.apply(rowIndex, axis=1)
10000 loops, best of 3: 163 µs per loop
1000 loops, best of 3: 286 µs per loop

EDIT

Looking at this question 3+ years later, you could just do:

In[15]:
df['d'],df['rowIndex'] = df['a'] + df['b'] * df['c'], df.index
df

Out[15]: 
   a  b  c   d  rowIndex
0  1  2  3   7         0
1  4  5  6  34         1

but assuming it isn't as trivial as this, whatever your rowFunc is really doing, you should look to use the vectorised functions, and then use them against the df index:

In[16]:
df['newCol'] = df['a'] + df['b'] + df['c'] + df.index
df

Out[16]: 
   a  b  c   d  rowIndex  newCol
0  1  2  3   7         0       6
1  4  5  6  34         1      16

This should work:

GetCountries():Observable<CountryData[]>  {
  return this.http.get(`http://services.groupkt.com/country/get/all`)
    .map((res:Response) => <CountryData[]>res.json());
}

For this to work you will need to import the following:

import 'rxjs/add/operator/map'

Using the :before pseudo-element,
CSS3's border-radius,
and some transparency is quite easy:

LIVE DEMO

<div class="circle"></div>

CSS:

.circle, .circle:before{
  position:absolute;
  border-radius:150px;  
}
.circle{  
  width:200px;
  height:200px;
  z-index:0;
  margin:11%;
  padding:40px;
  background: hsla(0, 100%, 100%, 0.6);   
}
.circle:before{
  content:'';
  display:block;
  z-index:-1;  
  width:200px;
  height:200px;

  padding:44px;
  border: 6px solid hsla(0, 100%, 100%, 0.6);
  /* 4px more padding + 6px border = 10 so... */  
  top:-10px;
  left:-10px; 
}

The :before attaches to our .circle another element which you only need to make (ok, block, absolute, etc...) transparent and play with the border opacity.

i found this one is more easy for preventing type error:

public enum Modes {
    some-really-long-string,
    mode1,
    mode2,
    mode3;

    String str;

    Modes(){
        this.str = super.name();
    }

    @Override
    @NonNull
    public String toString() {
        return str;
    }

however - this may work when you need to use a String on a log/println or whenever java compiles the toString() method automatically, but on a code line like this ->

// sample method that require (string,value)
intent.putExtra(Modes.mode1 ,shareElement.getMode()); // java error
// first argument enum does not return value

instead as mentioned above you will still have to extend the enum and use .name() in those cases like this:

intent.putExtra(Modes.mode1.name() ,shareElement.getMode()); 

When I'm working with csv files, I often use the pandas library. It makes things like this very easy. For example:

import pandas as pd

a = pd.read_csv("filea.csv")
b = pd.read_csv("fileb.csv")
b = b.dropna(axis=1)
merged = a.merge(b, on='title')
merged.to_csv("output.csv", index=False)

Some explanation follows. First, we read in the csv files:

>>> a = pd.read_csv("filea.csv")
>>> b = pd.read_csv("fileb.csv")
>>> a
   title  stage    jan    feb
0   darn  3.001  0.421  0.532
1     ok  2.829  1.036  0.751
2  three  1.115  1.146  2.921
>>> b
   title    mar    apr    may       jun  Unnamed: 5
0   darn  0.631  1.321  0.951    1.7510         NaN
1     ok  1.001  0.247  2.456    0.3216         NaN
2  three  0.285  1.283  0.924  956.0000         NaN

and we see there's an extra column of data (note that the first line of fileb.csv -- title,mar,apr,may,jun, -- has an extra comma at the end). We can get rid of that easily enough:

>>> b = b.dropna(axis=1)
>>> b
   title    mar    apr    may       jun
0   darn  0.631  1.321  0.951    1.7510
1     ok  1.001  0.247  2.456    0.3216
2  three  0.285  1.283  0.924  956.0000

Now we can merge a and b on the title column:

>>> merged = a.merge(b, on='title')
>>> merged
   title  stage    jan    feb    mar    apr    may       jun
0   darn  3.001  0.421  0.532  0.631  1.321  0.951    1.7510
1     ok  2.829  1.036  0.751  1.001  0.247  2.456    0.3216
2  three  1.115  1.146  2.921  0.285  1.283  0.924  956.0000

and finally write this out:

>>> merged.to_csv("output.csv", index=False)

producing:

title,stage,jan,feb,mar,apr,may,jun
darn,3.001,0.421,0.532,0.631,1.321,0.951,1.751
ok,2.829,1.036,0.751,1.001,0.247,2.456,0.3216
three,1.115,1.146,2.921,0.285,1.283,0.924,956.0

Prior to Java 8, you need to use the following:

Iterator<String> iterator = someList.iterator();

while (iterator.hasNext()) {
    String item = iterator.next();
    System.out.println(item);
}

However, with the introduction of Streams in Java 8 you can do same thing in much less syntax. For example, for your someList you can do:

someList.stream().forEach(System.out::println);

You can find more about streams here.

you could also use the "block-quote" property in CSS. That would make it so it doesn't effect your individual lines but allows you to set parameters for just the breaks between paragraphs or "block quotes".

UPDATE:
I stand corrected. "blockquote" is actually a html property. You use it just like < p > and < /p > around your work. You could then set the parameters for your block quote in css like

blockquote { margin-top: 20px }

Hope this helps. It is similar to setting the parameters on the br and may or may not be cross browser compatible.

Yes, you can!

$ ln -sfn source_file_or_directory_name softlink_name

I had the same error. My issue was using the wrong parameter name when binding.

Notice :tokenHash in the query, but :token_hash when binding. Fixing one or the other resolves the error in this instance.

// Prepare DB connection
$sql = 'INSERT INTO rememberedlogins (token_hash,user_id,expires_at)
        VALUES (:tokenHash,:user_id,:expires_at)';
$db = static::getDB();
$stmt = $db->prepare($sql);

// Bind values
$stmt->bindValue(':token_hash',$hashed_token,PDO::PARAM_STR);

Android Studio 3

The answers that talk about Maven Central are dated since Android Studio uses JCenter as the default repository center now. Your project's build.gradle file should have something like this:

repositories {
    google()
    jcenter()
}

So as long as the developer has their Maven repository there (which Picasso does), then all you would have to do is add a single line to the dependencies section of your app's build.gradle file.

dependencies {
    // ...
    implementation 'com.squareup.picasso:picasso:2.5.2'
}

I needed the same and this solution worked the most simple and straightforward way:

http://www.farinspace.com/jquery-scrollable-table-plugin/

I just give an id to the table I want to scroll and put one line in Javascript. That's it!

By the way, first I also thought I want to use a scrollable div, but it is not necessary at all. You can use a div and put it into it, but this solution does just what we need: scrolls the table.

This is how I do my store procedures for MSSQL with an autogenerated ID.

CREATE PROCEDURE [dbo].[InsertProducts]
    @id             INT             = NULL OUT,
    @name           VARCHAR(150)    = NULL,
    @desc           VARCHAR(250)    = NULL

AS

    INSERT INTO dbo.Products
       (Name,
        Description)
    VALUES
       (@name,
        @desc)

    SET @id = SCOPE_IDENTITY();

Another option with Filter

Filter(function(x) !all(is.na(x)), df)

NOTE: Data from @Simon O'Hanlon's post.

In your template, you have access to all the variables that are members of the current $scope. So, tobedone should be $scope.tobedone, and then you can display it with {{tobedone}}, or [[tobedone]] in your case.

According to Froyo source code, the Intent.EXTRA_INSTALLER_PACKAGE_NAME extra key is queried for the installer package name in the PackageInstallerActivity.

Use the getColor(Resources, int, Theme) method of the ResourcesCompat from the Android Support Library.

int white = ResourcesCompat.getColor(getResources(), R.color.white, null);

I think it reflect better your question than the getColor(Context, int) of the ContextCompat since you ask about Resources. Prior to API level 23, the theme will not be applied and the method calls through to getColor(int) but you'll not have the deprecated warning. The theme also may be null.

I think this should do the trick. I just added an if(isset and added concatenation to the variables in the body to separate PHP from HTML.

<?php
    $name = $_POST['name'];
    $email = $_POST['email'];
    $message = $_POST['message'];
    $from = 'From: yoursite.com'; 
    $to = '[email protected]'; 
    $subject = 'Customer Inquiry';
    $body = "From:" .$name."\r\n E-Mail:" .$email."\r\n Message:\r\n" .$message;

if (isset($_POST['submit'])) 
{
    if (mail ($to, $subject, $body, $from)) 
    { 
        echo '<p>Your message has been sent!</p>';
    } 
    else 
    { 
        echo '<p>Something went wrong, go back and try again!</p>'; 
    }
}

?>

I'd say the minimum would be to

• know one of the .Net Languages (C#, VB.NET, etc.)
• know the basic working of the .Net runtime
• know and understand the core parts of the .Net class libraries
• have an understanding about what additional classes and functions are available as part of the .Net class libraries

This comment syntax should work for you:

@* enter comments here *@

Look up the AbortException class for Jenkins. You should be able to use the methods to get back simple messages or stack traces. In a simple case, when making a call in a script block (as others have indicated), you can call getMessage() to get the string to echo to the user. Example:

script {
        try {
            sh "sudo docker rmi frontend-test"
        } catch (err) {
            echo err.getMessage()
            echo "Error detected, but we will continue."
        }
        ...continue with other code...
}

UPDATE

Now we need to use Custom Targets

SAMPLE CODE

    Glide.with(mContext)
            .asBitmap()
            .load("url")
            .into(new CustomTarget<Bitmap>() {
                @Override
                public void onResourceReady(@NonNull Bitmap resource, @Nullable Transition<? super Bitmap> transition) {

                }

                @Override
                public void onLoadCleared(@Nullable Drawable placeholder) {
                }
            });

How does one use glide to download an image into a bitmap?

The above all answer are correct but outdated

because in new version of Glide implementation 'com.github.bumptech.glide:glide:4.8.0'

You will find below error in code

• The .asBitmap() is not available in glide:4.8.0

• SimpleTarget<Bitmap> is deprecated

You probably never need a singleton in Python. Just define all your data and functions in a module and you have a de facto singleton:

import datetime
file_name=None

def set_file_name(new_file_name: str):
    global file_name
    file_name=new_file_name

def write(message: str):
    global file_name
    if file_name:
        with open(file_name, 'a+') as f:
            f.write("{} {}\n".format(datetime.datetime.now(), message))
    else:
        print("LOG: {}", message)

To use:

    import log
    log.set_file_name("debug.log")
    log.write("System starting")
    ...

If you really absolutely have to have a singleton class then I'd go with:

    class My_Singleton(object):
        def foo(self):
            pass

    my_singleton = My_Singleton()

To use:

    from mysingleton import my_singleton
    my_singleton.foo()

where mysingleton.py is your filename that My_Singleton is defined in. This works because after the first time a file is imported, Python doesn't re-execute the code.

It turns out that you can create 32-bit ODBC connections using C:\Windows\SysWOW64\odbcad32.exe. My solution was to create the 32-bit ODBC connection as a System DSN. This still didn't allow me to connect to it since .NET couldn't look it up. After significant and fruitless searching to find how to get the OdbcConnection class to look for the DSN in the right place, I stumbled upon a web site that suggested modifying the registry to solve a different problem.

I ended up creating the ODBC connection directly under HKLM\Software\ODBC. I looked in the SysWOW6432 key to find the parameters that were set up using the 32-bit version of the ODBC administration tool and recreated this in the standard location. I didn't add an entry for the driver, however, as that was not installed by the standard installer for the app either.

After creating the entry (by hand), I fired up my windows service and everything was happy.

Another alternative to use the exact json within javascript. As it is Javascript Object Notation you can just create your object directly with the json notation. If you store this in a .js file you can use the object in your application. This was a useful option for me when I had some static json data that I wanted to cache in a file separately from the rest of my app.

    //Just hard code json directly within JS
    //here I create an object CLC that represents the json!
    $scope.CLC = {
        "ContentLayouts": [
            {
                "ContentLayoutID": 1,
                "ContentLayoutTitle": "Right",

The problem could be that the Python libraries, per HTTP-Standard, first send an unauthenticated request, and then only if it's answered with a 401 retry, are the correct credentials sent. If the Foursquare servers don't do "totally standard authentication" then the libraries won't work.

Try using headers to do authentication:

import urllib2, base64

request = urllib2.Request("http://api.foursquare.com/v1/user")
base64string = base64.b64encode('%s:%s' % (username, password))
request.add_header("Authorization", "Basic %s" % base64string)   
result = urllib2.urlopen(request)

Had the same problem as you and found the solution from this thread: http://forums.shopify.com/categories/9/posts/27662

Update: Now supported in most major browsers

document.querySelector("p").closest(".near.ancestor")

Note that this can match selectors, not just classes

https://developer.mozilla.org/en-US/docs/Web/API/Element.closest

For legacy browsers that do not support closest() but have matches() one can build selector-matching similar to @rvighne's class matching:

function findAncestor (el, sel) {
    while ((el = el.parentElement) && !((el.matches || el.matchesSelector).call(el,sel)));
    return el;
}

See the MSDN reference table for maximum numbers/sizes.

Bytes per varchar(max), varbinary(max), xml, text, or image column: 2^31-1

There's a two-byte overhead for the column, so the actual data is 2^31-3 max bytes in length. Assuming you're using a single-byte character encoding, that's 2^31-3 characters total. (If you're using a character encoding that uses more than one byte per character, divide by the total number of bytes per character. If you're using a variable-length character encoding, all bets are off.)
