This is called an initialization list. It is a way of initializing class members. There are benefits to using this instead of simply assigning new values to the members in the body of the constructor, but if you have class members which are constants or references they must be initialized.

Workaround:

template<class T, size_t N>
struct simple_array { // like std::array in C++0x
   T arr[N];
};


class C : private simple_array<int, 3> 
{
      static simple_array<int, 3> myarr() {
           simple_array<int, 3> arr = {1,2,3};
           return arr;
      }
public:
      C() : simple_array<int, 3>(myarr()) {}
};

One technique that has become popular with memory management in C++ is RAII. Basically you use constructors/destructors to handle resource allocation. Of course there are some other obnoxious details in C++ due to exception safety, but the basic idea is pretty simple.

The issue generally comes down to one of ownership. I highly recommend reading the Effective C++ series by Scott Meyers and Modern C++ Design by Andrei Alexandrescu.

You could also use:

var latLon = L.latLng(40.737, -73.923);
var bounds = latLon.toBounds(500); // 500 = metres
map.panTo(latLon).fitBounds(bounds);

This will set the view level to fit the bounds in the map leaflet.

or:

SELECT coalesce(MAX(X), 0) AS MaxX
FROM tbl
WHERE XID = 1

You can't close an alert box with Javascript.

You could, however, use a window instead:

var w = window.open('','','width=100,height=100')
w.document.write('Message')
w.focus()
setTimeout(function() {w.close();}, 5000)

x is Unsigned hexadecimal integer ( 32 Bit )

p is Pointer address

See printf on the C++ Reference. Even if both of them would write the same, I would use %p to print a pointer.

#!/usr/bin/env bash
while [ "$1" != "" ]; do
  echo "Received: ${1}" && shift;
done;

Just thought this may be a bit more useful when trying to test how args come into your script

if (android.os.Build.VERSION.SDK_INT >= 21) {
            storeViewHolder.storeNameTextView.setImageDrawable(context.getResources().getDrawable(array[position], context.getTheme()));
} else {
            storeViewHolder.storeNameTextView.setImageDrawable(context.getResources().getDrawable(array[position]));
}

you use the scrollTop attribute

var position = document.getElementById('id').scrollTop;

<?php
    $res = mysql_query('SELECT getTreeNodeName(1) AS result');
    if ($res === false) {
        echo mysql_errno().': '.mysql_error();
    }
    while ($obj = mysql_fetch_object($res)) {
        echo $obj->result;
    }

You will have to open the file in one way or another if you want to access the data within it. Obviously, one way is to open it in your Excel application instance, e.g.:-

(untested code)

Dim wbk As Workbook
Set wbk = Workbooks.Open("C:\myworkbook.xls")

' now you can manipulate the data in the workbook anyway you want, e.g. '

Dim x As Variant
x = wbk.Worksheets("Sheet1").Range("A6").Value

Call wbk.Worksheets("Sheet2").Range("A1:G100").Copy
Call ThisWorbook.Worksheets("Target").Range("A1").PasteSpecial(xlPasteValues)
Application.CutCopyMode = False

' etc '

Call wbk.Close(False)

Another way to do it would be to use the Excel ADODB provider to open a connection to the file and then use SQL to select data from the sheet you want, but since you are anyway working from within Excel I don't believe there is any reason to do this rather than just open the workbook. Note that there are optional parameters for the Workbooks.Open() method to open the workbook as read-only, etc.

You can use Perl::Tidy for Perl.

I simplified your code to isolate the test for "%" being in the cell. Once you get that to work, you can add in the rest of your code.

Try this:

Option Explicit


Sub DoIHavePercentSymbol()
   Dim rng As Range

   Set rng = ActiveCell

   Do While rng.Value <> Empty
        If InStr(rng.Value, "%") = 0 Then
            MsgBox "I know nothing about percentages!"
            Set rng = rng.Offset(1)
            rng.Select
        Else
            MsgBox "I contain a % symbol!"
            Set rng = rng.Offset(1)
            rng.Select
        End If
   Loop

End Sub

InStr will return the number of times your search text appears in the string. I changed your if test to check for no matches first.

The message boxes and the .Selects are there simply for you to see what is happening while you are stepping through the code. Take them out once you get it working.

You need to use brackets when using the fileExists step in an if condition or assign the returned value to a variable

Using variable:

def exists = fileExists 'file'

if (exists) {
    echo 'Yes'
} else {
    echo 'No'
}

Using brackets:

if (fileExists('file')) {
    echo 'Yes'
} else {
    echo 'No'
}

I do it this way...

public static function multiExplode($delims, $string, $special = '|||') {

    if (is_array($delims) == false) {
        $delims = array($delims);
    }

    if (empty($delims) == false) {
        foreach ($delims as $d) {
            $string = str_replace($d, $special, $string);
        }
    }

    return explode($special, $string);
}

Like epascarello said, the server that hosts the resource needs to have CORS enabled. What you can do on the client side (and probably what you are thinking of) is set the mode of fetch to CORS (although this is the default setting I believe):

fetch(request, {mode: 'cors'});

However this still requires the server to enable CORS as well, and allow your domain to request the resource.

Check out the CORS documentation, and this awesome Udacity video explaining the Same Origin Policy.

You can also use no-cors mode on the client side, but this will just give you an opaque response (you can't read the body, but the response can still be cached by a service worker or consumed by some API's, like <img>):

fetch(request, {mode: 'no-cors'})
.then(function(response) {
  console.log(response); 
}).catch(function(error) {  
  console.log('Request failed', error)  
});

Yes you can. You can even test it:

var i = 0;_x000D_
var timer = setInterval(function() {_x000D_
  console.log(++i);_x000D_
  if (i === 5) clearInterval(timer);_x000D_
  console.log('post-interval'); //this will still run after clearing_x000D_
}, 200);

In this example, this timer clears when i reaches 5.

If i understand your question, you just want to be able to access items in a data frame (or list) by row:

x = matrix( ceiling(9*runif(20)), nrow=5  )   
colnames(x) = c("col1", "col2", "col3", "col4")
df = data.frame(x)      # create a small data frame

df[1,]                  # get the first row
df[3,]                  # get the third row
df[nrow(df),]           # get the last row

lf = as.list(df)        

lf[[1]]                 # get first row
lf[[3]]                 # get third row

etc.

The direct replacement is if/elif/else.

However, in many cases there are better ways to do it in Python. See "Replacements for switch statement in Python?".

Be sure there is nothing on your button (such a div or a trasparent img) that keeps from clicking the button. It sounds stupid, but sometimes we think that jQuery is not working and all that stuffs and the problem is on the positioning of DOM elements.

For MySQL, MariaDB

ALTER TABLE [table name] MODIFY COLUMN [column name] [data type] NULL

Use MODIFY COLUMN instead of ALTER COLUMN.

Following query helped me. Instead of using LIKE, you can use ~*.

select id, name from hosts where name ~* 'julia|lena|jack';

A very important distinction, which is easy to miss, is the default bheavior of these two functions, when it comes to exceptions.

I'll use this example to simulate a coroutine that will raise exceptions, sometimes -

import asyncio
import random


async def a_flaky_tsk(i):
    await asyncio.sleep(i)  # bit of fuzz to simulate a real-world example

    if i % 2 == 0:
        print(i, "ok")
    else:
        print(i, "crashed!")
        raise ValueError

coros = [a_flaky_tsk(i) for i in range(10)]

await asyncio.gather(*coros) outputs -

0 ok
1 crashed!
Traceback (most recent call last):
  File "/Users/dev/PycharmProjects/trading/xxx.py", line 20, in <module>
    asyncio.run(main())
  File "/Users/dev/.pyenv/versions/3.8.2/lib/python3.8/asyncio/runners.py", line 43, in run
    return loop.run_until_complete(main)
  File "/Users/dev/.pyenv/versions/3.8.2/lib/python3.8/asyncio/base_events.py", line 616, in run_until_complete
    return future.result()
  File "/Users/dev/PycharmProjects/trading/xxx.py", line 17, in main
    await asyncio.gather(*coros)
  File "/Users/dev/PycharmProjects/trading/xxx.py", line 12, in a_flaky_tsk
    raise ValueError
ValueError

As you can see, the coros after index 1 never got to execute.

But await asyncio.wait(coros) continues to execute tasks, even if some of them fail -

0 ok
1 crashed!
2 ok
3 crashed!
4 ok
5 crashed!
6 ok
7 crashed!
8 ok
9 crashed!

    raise ValueError
ValueError

Ofcourse, this behavior can be changed for both by using -

asyncio.gather(..., return_exceptions=True)

or,

asyncio.wait([...], return_when=asyncio.FIRST_EXCEPTION)

But it doesn't end here!

Notice: Task exception was never retrieved in the logs above.

asyncio.wait() won't re-raise exceptions from the child tasks until you await them individually. (The stacktrace in the logs are just messages, they cannot be caught!)

done, pending = await asyncio.wait(coros)
for tsk in done:
    try:
        await tsk
    except Exception as e:
        print("I caught:", repr(e))

Output -

0 ok
1 crashed!
2 ok
3 crashed!
4 ok
5 crashed!
6 ok
7 crashed!
8 ok
9 crashed!
I caught: ValueError()
I caught: ValueError()
I caught: ValueError()
I caught: ValueError()
I caught: ValueError()

On the other hand, to catch exceptions with asyncio.gather(), you must -

results = await asyncio.gather(*coros, return_exceptions=True)
for result_or_exc in results:
    if isinstance(result_or_exc, Exception):
        print("I caught:", repr(result_or_exc))

(Same output as before)

I'm with Git downloaded from https://git-scm.com/ and set up ssh follow to the answer for instructions https://stackoverflow.com/a/26130250/4058484.

Once the generated public key is verified in my Bitbucket account, and by referring to the steps as explaned on http://www.bohyunkim.net/blog/archives/2518 I found that just 'git push' is working:

git clone https://[email protected]/me/test.git
cd test
cp -R ../dummy/* .
git add .
git pull origin master 
git commit . -m "my first git commit" 
git config --global push.default simple
git push

It even works for to push on merging master to gh-pages in GitHub

git checkout gh-pages
git merge master
git push

Enclose the field in quotes, e.g.

field1_value,field2_value,"field 3,value",field4, etc...

See wikipedia.

Updated:

To encode a quote, use ", one double quote symbol in a field will be encoded as "", and the whole field will become """". So if you see the following in e.g. Excel:

---------------------------------------
| regular_value |,,,"|  ,"", |"""   |"|
---------------------------------------

the CSV file will contain:

regular_value,",,,""",","""",","""""""",""""

A comma is simply encapsulated using quotes, so , becomes ",".

A comma and quote needs to be encapsulated and quoted, so "," becomes """,""".

Using LEFT JOIN/IS NULL:

DELETE b FROM BLOB b 
  LEFT JOIN FILES f ON f.id = b.fileid 
      WHERE f.id IS NULL

Using NOT EXISTS:

DELETE FROM BLOB 
 WHERE NOT EXISTS(SELECT NULL
                    FROM FILES f
                   WHERE f.id = fileid)

Using NOT IN:

DELETE FROM BLOB
 WHERE fileid NOT IN (SELECT f.id 
                        FROM FILES f)

Warning

Whenever possible, perform DELETEs within a transaction (assuming supported - IE: Not on MyISAM) so you can use rollback to revert changes in case of problems.

if you don't want or need a typed object try:

using Newtonsoft.Json;
// ...   
dynamic json  = JsonConvert.DeserializeObject(str);

or try for a typed object try:

Foo json  = JsonConvert.DeserializeObject<Foo>(str)

string.find("substring") will help you. This function returns -1 when there is no substring.

In SQL you need to use GETDATE():

UPDATE table SET date = GETDATE();

There is no NOW() function.

To answer your question:

In a large table, since the function is evaluated for each row, you will end up getting different values for the updated field.

So, if your requirement is to set it all to the same date I would do something like this (untested):

DECLARE @currDate DATETIME;
SET @currDate = GETDATE();

UPDATE table SET date = @currDate;

This worked fine for me (C#):

byte[] iconBytes = null;
using (var dbConnection = new SQLiteConnection(DataSource))
{
    dbConnection.Open();
    using (var transaction = dbConnection.BeginTransaction())
    {
        using (var command = new SQLiteCommand(dbConnection))
        {
            command.CommandText = "SELECT icon FROM my_table";

            using (var reader = command.ExecuteReader())
            {
                while (reader.Read())
                {
                    if (reader["icon"] != null && !Convert.IsDBNull(reader["icon"]))
                    {
                        iconBytes = (byte[]) reader["icon"];
                    }
                }
            }
        }
        transaction.Commit();
    }
}

No need for chunking. Just cast to a byte array.

open Command line and type lodctr /r The p. counter will be resotred\recreated.

There is no need to skip it. http://technet.microsoft.com/en-us/library/cc774958.aspx

I've seen both methods been used in seed files.

// Uncomment the below to wipe the table clean before populating

DB::table('table_name')->truncate();

//or

DB::table('table_name')->delete();

Even though you can not use the first one if you want to set foreign keys.

Cannot truncate a table referenced in a foreign key constraint

So it might be a good idea to use the second one.

The problem is, you need a xsd schema for packages.config.

This is how you can create a schema (I found it here):

Open your Config file -> XML -> Create Schema

This would create a packages.xsd for you, and opens it in Visual Studio:

In my case, packages.xsd was created under this path:

C:\Users\MyUserName\AppData\Local\Temp

Now I don't want to reference the packages.xsd from a Temp folder, but I want it to be added to my solution and added to source control, so other users can get it... so I copied packages.xsd and pasted it into my solution folder. Then I added the file to my solution:

1. Copy packages.xsd in the same folder as your solution

2. From VS, right click on solution -> Add -> Existing Item... and then add packages.xsd

So, now we have created packages.xsd and added it to the Solution. All we need to do is to tell the config file to use this schema.

Open the config file, then from the top menu select:

XML -> Schemas...

Add your packages.xsd, and select Use this schema (see below)

Automated interactive rebase edit followed by commit revert ready for a do-over

I found myself fixing a past commit frequently enough that I wrote a script for it.

Here's the workflow:

1. git commit-edit <commit-hash>
   

   This will drop you at the commit you want to edit.

2. Fix and stage the commit as you wish it had been in the first place.

   (You may want to use git stash save to keep any files you're not committing)

3. Redo the commit with --amend, eg:

   git commit --amend
   

4. Complete the rebase:

   git rebase --continue
   

For the above to work, put the below script into an executable file called git-commit-edit somewhere in your $PATH:

#!/bin/bash

set -euo pipefail

script_name=${0##*/}

warn () { printf '%s: %s\n' "$script_name" "$*" >&2; }
die () { warn "$@"; exit 1; }

[[ $# -ge 2 ]] && die "Expected single commit to edit. Defaults to HEAD~"

# Default to editing the parent of the most recent commit
# The most recent commit can be edited with `git commit --amend`
commit=$(git rev-parse --short "${1:-HEAD~}")
message=$(git log -1 --format='%h %s' "$commit")

if [[ $OSTYPE =~ ^darwin ]]; then
  sed_inplace=(sed -Ei "")
else
  sed_inplace=(sed -Ei)
fi

export GIT_SEQUENCE_EDITOR="${sed_inplace[*]} "' "s/^pick ('"$commit"' .*)/edit \\1/"'
git rebase --quiet --interactive --autostash --autosquash "$commit"~
git reset --quiet @~ "$(git rev-parse --show-toplevel)"  # Reset the cache of the toplevel directory to the previous commit
git commit --quiet --amend --no-edit --allow-empty  #  Commit an empty commit so that that cache diffs are un-reversed

echo
echo "Editing commit: $message" >&2
echo

Try this:

Integer startIn = null;

try {
  startIn = Integer.valueOf(startField.getText());
} catch (NumberFormatException e) {
  .
  .
  .
}

if (startIn == null) {
  // Prompt for value...
}

@Bill Karwin describes three inheritance models in his SQL Antipatterns book, when proposing solutions to the SQL Entity-Attribute-Value antipattern. This is a brief overview:

Single Table Inheritance (aka Table Per Hierarchy Inheritance):

Using a single table as in your first option is probably the simplest design. As you mentioned, many attributes that are subtype-specific will have to be given a NULL value on rows where these attributes do not apply. With this model, you would have one policies table, which would look something like this:

+------+---------------------+----------+----------------+------------------+
| id   | date_issued         | type     | vehicle_reg_no | property_address |
+------+---------------------+----------+----------------+------------------+
|    1 | 2010-08-20 12:00:00 | MOTOR    | 01-A-04004     | NULL             |
|    2 | 2010-08-20 13:00:00 | MOTOR    | 02-B-01010     | NULL             |
|    3 | 2010-08-20 14:00:00 | PROPERTY | NULL           | Oxford Street    |
|    4 | 2010-08-20 15:00:00 | MOTOR    | 03-C-02020     | NULL             |
+------+---------------------+----------+----------------+------------------+

\------ COMMON FIELDS -------/          \----- SUBTYPE SPECIFIC FIELDS -----/

Keeping the design simple is a plus, but the main problems with this approach are the following:

• When it comes to adding new subtypes, you would have to alter the table to accommodate the attributes that describe these new objects. This can quickly become problematic when you have many subtypes, or if you plan to add subtypes on a regular basis.

• The database will not be able to enforce which attributes apply and which don't, since there is no metadata to define which attributes belong to which subtypes.

• You also cannot enforce NOT NULL on attributes of a subtype that should be mandatory. You would have to handle this in your application, which in general is not ideal.

Concrete Table Inheritance:

Another approach to tackle inheritance is to create a new table for each subtype, repeating all the common attributes in each table. For example:

This design will basically solve the problems identified for the single table method:

• Mandatory attributes can now be enforced with NOT NULL.

• Adding a new subtype requires adding a new table instead of adding columns to an existing one.

• There is also no risk that an inappropriate attribute is set for a particular subtype, such as the vehicle_reg_no field for a property policy.

• There is no need for the type attribute as in the single table method. The type is now defined by the metadata: the table name.

However this model also comes with a few disadvantages:

• The common attributes are mixed with the subtype specific attributes, and there is no easy way to identify them. The database will not know either.

• When defining the tables, you would have to repeat the common attributes for each subtype table. That's definitely not DRY.

• Searching for all the policies regardless of the subtype becomes difficult, and would require a bunch of UNIONs.

This is how you would have to query all the policies regardless of the type:

SELECT     date_issued, other_common_fields, 'MOTOR' AS type
FROM       policies_motor
UNION ALL
SELECT     date_issued, other_common_fields, 'PROPERTY' AS type
FROM       policies_property;

Note how adding new subtypes would require the above query to be modified with an additional UNION ALL for each subtype. This can easily lead to bugs in your application if this operation is forgotten.

Class Table Inheritance (aka Table Per Type Inheritance):

This is the solution that @David mentions in the other answer. You create a single table for your base class, which includes all the common attributes. Then you would create specific tables for each subtype, whose primary key also serves as a foreign key to the base table. Example:

CREATE TABLE policies (
   policy_id          int,
   date_issued        datetime,

   -- // other common attributes ...
);

CREATE TABLE policy_motor (
    policy_id         int,
    vehicle_reg_no    varchar(20),

   -- // other attributes specific to motor insurance ...

   FOREIGN KEY (policy_id) REFERENCES policies (policy_id)
);

CREATE TABLE policy_property (
    policy_id         int,
    property_address  varchar(20),

   -- // other attributes specific to property insurance ...

   FOREIGN KEY (policy_id) REFERENCES policies (policy_id)
);

This solution solves the problems identified in the other two designs:

• Mandatory attributes can be enforced with NOT NULL.

• Adding a new subtype requires adding a new table instead of adding columns to an existing one.

• No risk that an inappropriate attribute is set for a particular subtype.

• No need for the type attribute.

• Now the common attributes are not mixed with the subtype specific attributes anymore.

• We can stay DRY, finally. There is no need to repeat the common attributes for each subtype table when creating the tables.

• Managing an auto incrementing id for the policies becomes easier, because this can be handled by the base table, instead of each subtype table generating them independently.

• Searching for all the policies regardless of the subtype now becomes very easy: No UNIONs needed - just a SELECT * FROM policies.

I consider the class table approach as the most suitable in most situations.

The names of these three models come from Martin Fowler's book Patterns of Enterprise Application Architecture.

From looking at the source code, it seems like the pg_stat_database query gives you the number of connections to the current database for all users. On the other hand, the pg_stat_activity query gives the number of connections to the current database for the querying user only.

You can try the %v, %+v or %#v verbs of go fmt:

fmt.Printf("%v", projects)

If your array (or here slice) contains struct (like Project), you will see their details.
For more precision, you can use %#v to print the object using Go-syntax, as for a literal:

%v  the value in a default format.
    when printing structs, the plus flag (%+v) adds field names
%#v a Go-syntax representation of the value

For basic types, fmt.Println(projects) is enough.

Note: for a slice of pointers, that is []*Project (instead of []Project), you are better off defining a String() method in order to display exactly what you want to see (or you will see only pointer address).
See this play.golang example.

You dont actually need the @Query annotation at all.

You can just use the following

    @Repository("registerUserRepository")
    public interface RegisterUserRepository extends JpaRepository<Registration,Long>{
    
    List<Registration> findByPlaceIgnoreCaseContaining(String place);

    }

Constraints dictate what values are valid for data in the database. For example, you can enforce the a value is not null (a NOT NULL constraint), or that it exists as a unique constraint in another table (a FOREIGN KEY constraint), or that it's unique within this table (a UNIQUE constraint or perhaps PRIMARY KEY constraint depending on your requirements). More general constraints can be implemented using CHECK constraints.

The MSDN documentation for SQL Server 2008 constraints is probably your best starting place.

I assume your tables are table1 and table2 respectively, and your solution is;

(select * from table1 MINUS select * from table2)
UNION ALL
(select * from table2 MINUS select * from table1)

Replace

Python 3 range

Rest all same.

You could get the first element in the array_keys() function as well. Or array_search() the keys for the "index" of a key. If you are inside a foreach loop, the simple incrementing counter (suggested by kip or cletus) is probably your most efficient method though.

<?php
   $array = array('test', '1', '2');
   $keys = array_keys($array);
   var_dump($keys[0]); // int(0)

   $array = array('test'=>'something', 'test2'=>'something else');
   $keys = array_keys($array);

   var_dump(array_search("test2", $keys)); // int(1)     
   var_dump(array_search("test3", $keys)); // bool(false)

No, it is not okay to put a link element in the body tag. See the specification (links to the HTML4.01 specs, but I believe it is true for all versions of HTML):

“This element defines a link. Unlike A, it may only appear in the HEAD section of a document, although it may appear any number of times.”

Here's what I've found. If you want an app to open on your secondary monitor by default do the following:

1. Open the application.
2. Re-size the window so that it is not maximized or minimized.
3. Move the window to the monitor you want it to open on by default.
4. Close the application.  Do not re-size prior to closing.
5. Open the application.
   It should open on the monitor you just moved it to and closed it on.
6. Maximize the window.

The application will now open on this monitor by default. If you want to change it to another monitor, just follow steps 1-6 again.

FailedPreconditionError: Attempting to use uninitialized value is one of the most frequent errors related to tensorflow. From official documentation, FailedPreconditionError

This exception is most commonly raised when running an operation that reads a tf.Variable before it has been initialized.

In your case the error even explains what variable was not initialized: Attempting to use uninitialized value Variable_1. One of the TF tutorials explains a lot about variables, their creation/initialization/saving/loading

Basically to initialize the variable you have 3 options:

• initialize all global variables with tf.global_variables_initializer()
• initialize variables you care about with tf.variables_initializer(list_of_vars). Notice that you can use this function to mimic global_variable_initializer: tf.variable_initializers(tf.global_variables())
• initialize only one variable with var_name.initializer

I almost always use the first approach. Remember you should put it inside a session run. So you will get something like this:

with tf.Session() as sess:
    sess.run(tf.global_variables_initializer())

If your are curious about more information about variables, read this documentation to know how to report_uninitialized_variables and check is_variable_initialized.

The command palette tells you the colours and their order when col = somefactor. It can also be used to set the colours as well.

palette()
[1] "black"   "red"     "green3"  "blue"    "cyan"    "magenta" "yellow"  "gray"   

In order to see that in your graph you could use a legend.

legend('topright', legend = levels(iris$Species), col = 1:3, cex = 0.8, pch = 1)

You'll notice that I only specified the new colours with 3 numbers. This will work like using a factor. I could have used the factor originally used to colour the points as well. This would make everything logically flow together... but I just wanted to show you can use a variety of things.

You could also be specific about the colours. Try ?rainbow for starters and go from there. You can specify your own or have R do it for you. As long as you use the same method for each you're OK.

Date() is not part of jQuery, it is one of JavaScript's features.

See the documentation on Date object.

You can do it like that:

var d = new Date();

var month = d.getMonth()+1;
var day = d.getDate();

var output = d.getFullYear() + '/' +
    (month<10 ? '0' : '') + month + '/' +
    (day<10 ? '0' : '') + day;

See this jsfiddle for a proof.

The code may look like a complex one, because it must deal with months & days being represented by numbers less than 10 (meaning the strings will have one char instead of two). See this jsfiddle for comparison.

Binary to Decimal

int(binaryString, 2)

Decimal to Binary

format(decimal ,"b")

//Disable future dates after current date

$("#datepicker").datepicker('setEndDate', new Date());

//Disable past dates after current date

$("#datepicker").datepicker('setEndDate', new Date());

Enjoy it...

int i = 0;
string s = "123";
i =int.Parse(s);
i = Convert.ToInt32(s);

As already mentioned, you can use the backticks or $(cat filename).

What was not mentioned, and I think is important to note, is that you must remember that the shell will break apart the contents of that file according to whitespace, giving each "word" it finds to your command as an argument. And while you may be able to enclose a command-line argument in quotes so that it can contain whitespace, escape sequences, etc., reading from the file will not do the same thing. For example, if your file contains:

a "b c" d

the arguments you will get are:

a
"b
c"
d

If you want to pull each line as an argument, use the while/read/do construct:

while read i ; do command_name $i ; done < filename

As of February 2020, for Android Studio 3.5.3, the simplest answer I found is this video.

Note 1: At 01.24 "Find" tab appears below. Click "Do Refactor" and continue as in the video.

Note 2: If you have any Java/Kotlin files "Marked as Plain Text" you need to modify the package name at the top manually, i.e. package com.example.thisplaceneedstobemanuallyupdated

Note 3: Be careful about letter cases while renaming, just as in the video.

Note 4: If you want to update the project name on title bar of project window, modify rootProject.name = 'YourProjectName' inside "settings.gradle" file under "Gradle Scripts" directory.

Just use a placeholder tag in your input instead of value

Be careful with permissions, it is problably you don't have some of them. You can see it in settings -> apps -> name of the application -> permissions -> active if not.

I got this error when I had a filename and class exported mismatch:

filename: list.component.ts

class exported: ListStudentsComponent

Changing from ListStudentsComponent to ListComponent fixed my issue.

You can get the current timestamp appended with a file extension in the following way:

String fileName = new Date().getTime() + ".txt";

Make the following changes in your Registry and it should work:

As a rephrasing of Andrey's answer:

The Boost TypeIndex library can be used to print names of types.

Inside a template, this might read as follows

#include <boost/type_index.hpp>
#include <iostream>

template<typename T>
void printNameOfType() {
    std::cout << "Type of T: " 
              << boost::typeindex::type_id<T>().pretty_name() 
              << std::endl;
}

I've found examples, where PyPy is slower than Python. But: Only on Windows.

C:\Users\User>python -m timeit -n10 -s"from sympy import isprime" "isprime(2**521-1);isprime(2**1279-1)"
10 loops, best of 3: 294 msec per loop

C:\Users\User>pypy -m timeit -n10 -s"from sympy import isprime" "isprime(2**521-1);isprime(2**1279-1)"
10 loops, best of 3: 1.33 sec per loop

So, if you think of PyPy, forget Windows. On Linux, you can achieve awesome accelerations. Example (list all primes between 1 and 1,000,000):

from sympy import sieve
primes = list(sieve.primerange(1, 10**6))

This runs 10(!) times faster on PyPy than on Python. But not on windows. There it is only 3x as fast.

Method Load of DataTable executes NextResult on the DataReader, so you shouldn't call NextResult explicitly when using Load, otherwise odd tables in the sequence would be omitted.

Here is a generic solution to load multiple tables using a DataReader.

// your command initialization code here
// ...
DataSet ds = new DataSet();
DataTable t;
using (DbDataReader reader = command.ExecuteReader())
{
  while (!reader.IsClosed)
  {
    t = new DataTable();
    t.Load(rs);
    ds.Tables.Add(t);
  }
}

Unique ID with count information

import java.util.concurrent.atomic.AtomicLong;

public class RandomIdUtils {

    private static AtomicLong atomicCounter = new AtomicLong();

    public static String createId() {

        String currentCounter = String.valueOf(atomicCounter.getAndIncrement());
        String uniqueId = UUID.randomUUID().toString();

        return uniqueId + "-" + currentCounter;
    }
}

As APC rightly pointed out, your start_date column appears to be a TIMESTAMP but it could be a TIMESTAMP WITH LOCAL TIMEZONE or TIMESTAMP WITH TIMEZONE datatype too. These could well influence any queries you were doing on the data if your database server was in a different timezone to yourself. However, let's keep this simple and assume you are in the same timezone as your server. First, to give you the confidence, check that the start_date is a TIMESTAMP data type.

Use the SQLPlus DESCRIBE command (or the equivalent in your IDE) to verify this column is a TIMESTAMP data type.

eg

DESCRIBE mytable

Should report :

Name        Null? Type
----------- ----- ------------
NAME              VARHAR2(20) 
START_DATE        TIMESTAMP

If it is reported as a Type = TIMESTAMP then you can query your date ranges with simplest TO_TIMESTAMP date conversion, one which requires no argument (or picture).

We use TO_TIMESTAMP to ensure that any index on the START_DATE column is considered by the optimizer. APC's answer also noted that a function based index could have been created on this column and that would influence the SQL predicate but we cannot comment on that in this query. If you want to know how to find out what indexes have been applied to table, post another question and we can answer that separately.

So, assuming there is an index on start_date, which is a TIMESTAMP datatype and you want the optimizer to consider it, your SQL would be :

select * from mytable where start_date between to_timestamp('15-JAN-10') AND to_timestamp('17-JAN-10')+.9999999

+.999999999 is very close to but isn't quite 1 so the conversion of 17-JAN-10 will be as close to midnight on that day as possible, therefore you query returns both rows.

The database will see the BETWEEN as from 15-JAN-10 00:00:00:0000000 to 17-JAN-10 23:59:59:99999 and will therefore include all dates from 15th,16th and 17th Jan 2010 whatever the time component of the timestamp.

Hope that helps.

    format: "yyyy",

}

This is how I do it if I need a form displayed for each item, and inputs for various properties. Really depends on what I'm trying to do though.

ViewModel looks like this:

public class MyViewModel
{
   public List<Person> Persons{get;set;}
}

View(with BeginForm of course):

@model MyViewModel


@for( int i = 0; i < Model.Persons.Count(); ++i)
{
    @Html.HiddenFor(m => m.Persons[i].PersonId)
    @Html.EditorFor(m => m.Persons[i].FirstName) 
    @Html.EditorFor(m => m.Persons[i].LastName)         
}

Action:

[HttpPost]public ViewResult(MyViewModel vm)
{
...

Note that on post back only properties which had inputs available will have values. I.e., if Person had a .SSN property, it would not be available in the post action because it wasn't a field in the form.

Note that the way MVC's model binding works, it will only look for consecutive ID's. So doing something like this where you conditionally hide an item will cause it to not bind any data after the 5th item, because once it encounters a gap in the IDs, it will stop binding. Even if there were 10 people, you would only get the first 4 on the postback:

@for( int i = 0; i < Model.Persons.Count(); ++i)
{
    if(i != 4)//conditionally hide 5th item, 
    { //but BUG occurs on postback, all items after 5th will not be bound to the the list
      @Html.HiddenFor(m => m.Persons[i].PersonId)
      @Html.EditorFor(m => m.Persons[i].FirstName) 
      @Html.EditorFor(m => m.Persons[i].LastName)           
    }
}

Kotlin Version of Terel answer

(fragmentManager.findFragmentByTag(TAG) as? DialogFragment)?.dismiss()

The solution (which other answers don't mention—at least at the time of my originally writing this) is that when PHP refers to delimiters, it's not referring to the delimiters you see in your code (which are quote marks) but the next characters inside the string. (In fact I've never seen this stated anywhere in any documentation: you have to see it in examples.) So instead of having a regular expression syntax like what you may be accustomed to from many other languages:

/something/

PHP uses strings, and then looks inside the string for another delimiter:

'/something/'

The delimiter PHP is referring to is the pair of / characters, instead of the pair of ' characters. So if you write 'something', PHP will take s as the intended delimiter and complain that you're not allowed to use alphanumeric characters as your delimiter.

So if you want to pass (for instance) an i to show that you want a case-insensitve match, you pass it inside the string but outside of the regex delimiters:

'/something/i'

If you want to use something other than / as your delimiter, you can, such as if you're matching a URL and don't want to have to escape all the slashes:

'~something~'

Empty array for empty collections and null for everything else.

To be quite frank, some of the suggested solutions are really slow, and therefore are bad suggestions. For testing a single number to be prime you need some dividing/modulo operator, but for calculating a range you don't have to.

Basically you just exclude numbers that are multiples of earlier found primes, as the are (by definition) not primes themselves.

I will not give the full implementation, as that would be to easy, this is the approach in pseudo code. (On my machine, the actual implementation calculates all primes in an Sytem.Int32 (2 bilion) within 8 seconds.

public IEnumerable<long> GetPrimes(long max)
{
    // we safe the result set in an array of bytes.
    var buffer = new byte[long >> 4];
    // 1 is not a prime.
    buffer[0] = 1;

    var iMax = (long)Math.Sqrt(max);

    for(long i = 3; i <= iMax; i +=2 )
    {
        // find the index in the buffer
        var index = i >> 4;
        // find the bit of the buffer.
        var bit = (i >> 1) & 7;

        // A not set bit means: prime
        if((buffer[index] & (1 << bit)) == 0)
        {
            var step = i << 2;
            while(step < max)
            {
                // find position in the buffer to write bits that represent number that are not prime.
            }
        }
        // 2 is not in the buffer.
        yield return 2;

        // loop through buffer and yield return odd primes too.
    }
}

The solution requires a good understanding of bitwise operations. But it ways, and ways faster. You also can safe the result of the outcome on disc, if you need them for later use. The result of 17 * 10^9 numbers can be safed with 1 GB, and the calculation of that result set takes about 2 minutes max.

You probably don't actually want to change your default Python.

Your distro installed a standard system Python in /usr/bin, and may have scripts that depend on this being present, and selected by #! /usr/bin/env python. You can usually get away with running Python 2.6 scripts in 2.7, but do you want to risk it?

On top of that, monkeying with /usr/bin can break your package manager's ability to manage packages. And changing the order of directories in your PATH will affect a lot of other things besides Python. (In fact, it's more common to have /usr/local/bin ahead of /usr/bin, and it may be what you actually want—but if you have it the other way around, presumably there's a good reason for that.)

But you don't need to change your default Python to get the system to run 2.7 when you type python.

First, you can set up a shell alias:

alias python=/usr/local/bin/python2.7

Type that at a prompt, or put it in your ~/.bashrc if you want the change to be persistent, and now when you type python it runs your chosen 2.7, but when some program on your system tries to run a script with /usr/bin/env python it runs the standard 2.6.

Alternatively, just create a virtual environment out of your 2.7 (or separate venvs for different projects), and do your work inside the venv.

A multiprogramming is the process when a computer system is performing different tasks all at once in a single computer system.

Supposing you desire the following features:

1. Source file behaves properly in your debugger (filename shows in stack, etc)
2. __name__ == '__main__' is True so scripts behave properly as scripts.

The exec(open('foo.py').read()) fails feature 1 The import foo strategy fails feature 2

To get both, you need this:

    source = open(filename).read()
    code = compile(source, filename, 'exec')
    exec(code)

An example, available for POSIX compliant systems :

/*
 * This program displays the names of all files in the current directory.
 */

#include <dirent.h> 
#include <stdio.h> 

int main(void) {
  DIR *d;
  struct dirent *dir;
  d = opendir(".");
  if (d) {
    while ((dir = readdir(d)) != NULL) {
      printf("%s\n", dir->d_name);
    }
    closedir(d);
  }
  return(0);
}

Beware that such an operation is platform dependant in C.

Is you want a plus (+) symbol in the body you have to encode it as 2B.

For example: Try this

To add an element to an array you need to use the format:

array[index] = element;

Where array is the array you declared, index is the position where the element will be stored, and element is the item you want to store in the array.

In your code, you'd want to do something like this:

int[] num = new int[args.length];
for (int i = 0; i < args.length; i++) {
    int neki = Integer.parseInt(args[i]);
    num[i] = neki;
}

The add() method is available for Collections like List and Set. You could use it if you were using an ArrayList (see the documentation), for example:

List<Integer> num = new ArrayList<>();
for (String s : args) {
    int neki = Integer.parseInt(s);
    num.add(neki);
}

Build your own script to install global dependencies. It doesn't take much. package.json is quite expandable.

const {execSync} = require('child_process');

JSON.parse(fs.readFileSync('package.json'))
     .globalDependencies.foreach(
         globaldep => execSync('npm i -g ' + globaldep)
     );

Using the above, you can even make it inline, below!

Look at preinstall below:

{
  "name": "Project Name",
  "version": "0.1.0",
  "description": "Project Description",
  "main": "app.js",
  "scripts": {
    "preinstall": "node -e \"const {execSync} = require('child_process'); JSON.parse(fs.readFileSync('package.json')).globalDependencies.foreach(globaldep => execSync('npm i -g ' + globaldep));\"",
    "build": "your transpile/compile script",
    "start": "node app.js",
    "test": "./node_modules/.bin/mocha --reporter spec",

I had found a particular case where swiping (ADB shell input touchscreen swipe ... ) to unlock the home screen doesn't work. More exactly for Acer Z160 and Acer S57. The phones are history but still, they need to be taken into consideration by us developers. Here is the code source that solved my problem. I had made my app to start with the device. and in the "onCreate" function I had changed temporarily the lock type.

Also, just in case google drive does something to the zip file I will post fragments of that code below.

A primary key is not required. A foreign key is not required either. You can construct a query joining two tables on any column you wish as long as the datatypes either match or are converted to match. No relationship needs to explicitly exist.

To do this you use an outer join:

select tablea.code, tablea.name, tableb.location from tablea left outer join 
tableb on tablea.code = tableb.code

join with out relation

SQL join

You can use pure Javascript to achieve this:

var test = true;
if (typeof test === 'boolean')
   console.log('test is a boolean!');

The following syntax fixes it for you:

curl -v -F key1=value1 -F upload=@localfilename URL

This can be done with java reflection,This method returns false if any one attribute value is present for the object ,hope it helps some one

public boolean isEmpty()  {

    for (Field field : this.getClass().getDeclaredFields()) {
        try {
            field.setAccessible(true);
            if (field.get(this)!=null) {
                return false;
            }
        } catch (Exception e) {
          System.out.println("Exception occured in processing");
        }
    }
    return true;
}

Should be

~/([^/]*)$~

Means: Match a / and then everything, that is not a / ([^/]*) until the end ($, "end"-anchor).

I use the ~ as delimiter, because now I don't need to escape the forward-slash /.

For EF 4.1,

var objectContext = (myEntities as IObjectContextAdapter).ObjectContext;
objectContext.ExecuteStoreCommand("delete from [myTable];");

"Preprocess" in R:

lines <- "www, rrr, 1,234, ttt \n rrr,zzz, 1,234,567,987, rrr"

Can use readLines on a textConnection. Then remove only the commas that are between digits:

gsub("([0-9]+)\\,([0-9])", "\\1\\2", lines)

## [1] "www, rrr, 1234, ttt \n rrr,zzz, 1234567987, rrr"

It's als useful to know but not directly relevant to this question that commas as decimal separators can be handled by read.csv2 (automagically) or read.table(with setting of the 'dec'-parameter).

Edit: Later I discovered how to use colClasses by designing a new class. See:

How to load df with 1000 separator in R as numeric class?

If you are using transition instead of transform, -webkit-backface-visibility: hidden; does not work. A jagged edge appears during animation for a transparent png file.

To solve it I used: outline: 1px solid transparent;

To make use of an index before using the BINARY, you could do something like this if you have large tables.

SELECT
   *
FROM
   (SELECT * FROM `table` WHERE `column` = 'value') as firstresult
WHERE
   BINARY `column` = 'value'

The subquery would result in a really small case-insensitive subset of which you then select the only case-sensitive match.

you can use this code date and time time is 24 h

INSERT INTO TABLE_NAME(
  date_column
)values(
  TO_DATE('2016-10-05 10:53:56', 'SYYYY-MM-DD HH24:MI:SS')
)

Quote from there:

the rules for index usage with LIKE are loosely like this:

• If your filter criteria uses equals = and the field is indexed, then most likely it will use an INDEX/CLUSTERED INDEX SEEK

• If your filter criteria uses LIKE, with no wildcards (like if you had a parameter in a web report that COULD have a % but you instead use the full string), it is about as likely as #1 to use the index. The increased cost is almost nothing.

• If your filter criteria uses LIKE, but with a wildcard at the beginning (as in Name0 LIKE '%UTER') it's much less likely to use the index, but it still may at least perform an INDEX SCAN on a full or partial range of the index.

• HOWEVER, if your filter criteria uses LIKE, but starts with a STRING FIRST and has wildcards somewhere AFTER that (as in Name0 LIKE 'COMP%ER'), then SQL may just use an INDEX SEEK to quickly find rows that have the same first starting characters, and then look through those rows for an exact match.

(Also keep in mind, the SQL engine still might not use an index the way you're expecting, depending on what else is going on in your query and what tables you're joining to. The SQL engine reserves the right to rewrite your query a little to get the data in a way that it thinks is most efficient and that may include an INDEX SCAN instead of an INDEX SEEK)

Using Retrofit 2.0 you may use this:

@Multipart
    @POST("uploadImage")
    Call<ResponseBody> uploadImage(@Part("file\"; fileName=\"myFile.png\" ")RequestBody requestBodyFile, @Part("image") RequestBody requestBodyJson);

Make a request:

File imgFile = new File("YOUR IMAGE FILE PATH");
RequestBody requestBodyFile = RequestBody.create(MediaType.parse("image/*"), imgFile);
RequestBody requestBodyJson = RequestBody.create(MediaType.parse("text/plain"),
                    retrofitClient.getJsonObject(uploadRequest));



//make sync call
Call<ResponseBody> uploadBundle = uploadImpl.uploadImage(requestBodyFile, requestBodyJson);
Response<BaseResponse> response = uploadBundle.execute();

I've had good luck with the SWF::File library on CPAN, and particularly the dumpswf.plx tool that comes with that distribution. It generates Perl code that, when run, regenerates your SWF.

function initialize() {
    var location = new google.maps.LatLng(44.5403, -78.5463);
    var mapCanvas = document.getElementById('map_canvas');
    var map_options = {
      center: location,
      zoom: 15,
      mapTypeId: google.maps.MapTypeId.ROADMAP
    }
    var map = new google.maps.Map(map_canvas, map_options);

    new google.maps.Marker({
        position: location,
        map: map
    });
}
google.maps.event.addDomListener(window, 'load', initialize);

I had problems importing SKLEARN after installing a new 64bit version of Python 3.4 from python.org.

Note: This answer is somewhat intended to be a joke, but it actually does work...

#!/bin/bash
outfile="/tmp/$RANDOM"
cfile="$outfile.c"
echo '#include <stdio.h>
int main(void){int e=1;char c;while((c=getc(stdin))!=-1){if(c==10)e=1;if(c==32)e=0;if(e)putc(c,stdout);}}' >> "$cfile"
gcc -o "$outfile" "$cfile"
rm "$cfile"
cat somedata.txt | "$outfile"
rm "$outfile"

You can replace cat somedata.txt with a different command.

You could use multiple background: linear-gradient(); calls, but try this:

If you want the images to be completely fused together where it doesn't look like the elements load separately due to separate HTTP requests then use this technique. Here we're loading two things on the same element that load simultaneously...

Just make sure you convert your pre-rendered 32-bit transparent png image/texture to base64 string first and use it within the background-image css call (in place of INSERTIMAGEBLOBHERE in this example).

I used this technique to fuse a wafer looking texture and other image data that's serialized with a standard rgba transparency / linear gradient css rule. Works better than layering multiple art and wasting HTTP requests which is bad for mobile. Everything is loaded client side with no file operation required, but does increase document byte size.

 div.imgDiv   {
      background: linear-gradient(to right bottom, white, rgba(255,255,255,0.95), rgba(255,255,255,0.95), rgba(255,255,255,0.9), rgba(255,255,255,0.9), rgba(255,255,255,0.85), rgba(255,255,255,0.8) );
      background-image: url("data:image/png;base64,INSERTIMAGEBLOBHERE");
 }

Try this:

long length = f.length();

When your scenario is simple you can use

import store from '../store';

export const SOME_ACTION = 'SOME_ACTION';
export function someAction() {
  return {
    type: SOME_ACTION,
    items: store.getState().otherReducer.items,
  }
}

But sometimes your action creator need to trigger multi actions

for example async request so you need REQUEST_LOAD REQUEST_LOAD_SUCCESS REQUEST_LOAD_FAIL actions

export const [REQUEST_LOAD, REQUEST_LOAD_SUCCESS, REQUEST_LOAD_FAIL] = [`REQUEST_LOAD`
    `REQUEST_LOAD_SUCCESS`
    `REQUEST_LOAD_FAIL`
]
export function someAction() {
    return (dispatch, getState) => {
        const {
            items
        } = getState().otherReducer;
        dispatch({
            type: REQUEST_LOAD,
            loading: true
        });
        $.ajax('url', {
            success: (data) => {
                dispatch({
                    type: REQUEST_LOAD_SUCCESS,
                    loading: false,
                    data: data
                });
            },
            error: (error) => {
                dispatch({
                    type: REQUEST_LOAD_FAIL,
                    loading: false,
                    error: error
                });
            }
        })
    }
}

Note: you need redux-thunk to return function in action creator

Key points which explain difference and provide guidance upon working with unittest.mock

1. Use Mock if you want to replace some interface elements(passing args) of the object under test
2. Use patch if you want to replace internal call to some objects and imported modules of the object under test
3. Always provide spec from the object you are mocking
   • With patch you can always provide autospec
   • With Mock you can provide spec
   • Instead of Mock, you can use create_autospec, which intended to create Mock objects with specification.

In the question above the right answer would be to use Mock, or to be more precise create_autospec (because it will add spec to the mock methods of the class you are mocking), the defined spec on the mock will be helpful in case of an attempt to call method of the class which doesn't exists ( regardless signature), please see some

from unittest import TestCase
from unittest.mock import Mock, create_autospec, patch


class MyClass:
    
    @staticmethod
    def method(foo, bar):
        print(foo)


def something(some_class: MyClass):
    arg = 1
    # Would fail becuase of wrong parameters passed to methd.
    return some_class.method(arg)


def second(some_class: MyClass):
    arg = 1
    return some_class.unexisted_method(arg)


class TestSomethingTestCase(TestCase):
    def test_something_with_autospec(self):
        mock = create_autospec(MyClass)
        mock.method.return_value = True
        # Fails because of signature misuse.
        result = something(mock)
        self.assertTrue(result)
        self.assertTrue(mock.method.called)
    
    def test_something(self):
        mock = Mock()  # Note that Mock(spec=MyClass) will also pass, because signatures of mock don't have spec.
        mock.method.return_value = True
        
        result = something(mock)
        
        self.assertTrue(result)
        self.assertTrue(mock.method.called)
        
    def test_second_with_patch_autospec(self):
        with patch(f'{__name__}.MyClass', autospec=True) as mock:
            # Fails because of signature misuse.
            result = second(mock)
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)


class TestSecondTestCase(TestCase):
    def test_second_with_autospec(self):
        mock = Mock(spec=MyClass)
        # Fails because of signature misuse.
        result = second(mock)
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)
    
    def test_second_with_patch_autospec(self):
        with patch(f'{__name__}.MyClass', autospec=True) as mock:
            # Fails because of signature misuse.
            result = second(mock)
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)
    
    def test_second(self):
        mock = Mock()
        mock.unexisted_method.return_value = True
        
        result = second(mock)
        
        self.assertTrue(result)
        self.assertTrue(mock.unexisted_method.called)

The test cases with defined spec used fail because methods called from something and second functions aren't complaint with MyClass, which means - they catch bugs, whereas default Mock will display.

As a side note there is one more option: use patch.object to mock just the class method which is called with.

The good use cases for patch would be the case when the class is used as inner part of function:

def something():
    arg = 1
    return MyClass.method(arg)

Then you will want to use patch as a decorator to mock the MyClass.

If you want to return some value then wrap your statement in function

function my_function(){ 

 return my_thing; 
}

Problem is with the statement on the 1st line if you are trying to use PHP

var ask = confirm ('".$message."'); 

IF you are trying to use PHP you should use

 var ask = confirm (<?php echo "'".$message."'" ?>); //now message with be the javascript string!!

I've tried the solution presented in the accepted answer and it did not work for me. I wanted to share what DID work for me as it might help someone else. I've found this solution here.

Basically what you need to do is put your .so files inside a a folder named lib (Note: it is not libs and this is not a mistake). It should be in the same structure it should be in the APK file.

In my case it was:
Project:
|--lib:
|--|--armeabi:
|--|--|--.so files.

So I've made a lib folder and inside it an armeabi folder where I've inserted all the needed .so files. I then zipped the folder into a .zip (the structure inside the zip file is now lib/armeabi/*.so) I renamed the .zip file into armeabi.jar and added the line compile fileTree(dir: 'libs', include: '*.jar') into dependencies {} in the gradle's build file.

This solved my problem in a rather clean way.

Your code is passing a function as an argument to find. That function takes an element argument (of type Conversation) and returns void (meaning there is no return value). TypeScript describes this as (element: Conversation) => void'

What TypeScript is saying is that the find function doesn't expect to receive a function that takes a Conversation and returns void. It expects a function that takes a Conversations, a number and a Conversation array, and that this function should return a boolean.

So bottom line is that you either need to change your code to pass in the values to find correctly, or else you need to provide an overload to the definition of find in your definition file that accepts a Conversation and returns void.

You can use also archive this with the Fastify framework:

const { readFileSync } = require('fs')
const Fastify = require('fastify')

const fastify = Fastify({

Change JDK version to 1.8

1. Language level File -> project Structure -> Modules -> Sources -> Language level -> 8-Lambdas, type annotations etc.

2. Project SDk File -> project Structure -> Project 1.8

3. Java compiler File -> Settings -> Build, Executions, Deployment -> Compiler -> Java compiler

Java rule : One public class in one file.

Try to specify the port in

conn = DriverManager.getConnection("jdbc:mysql://localhost/mysql?"
                                        + "user=root&password=onelife");

I think you should have something like this:

conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/mysql?"
                                            + "user=root&password=onelife");

Also, the port number in my example (3306) is the default port, but you may change it while installing MySQL.

I think that a better way to specify password and user is to separate them from the URL like this:

connection = DriverManager.getConnection(url, login, password);

If you are a developer, this is what you need to do:

<!DOCTYPE html>
<html lang="en">
<head>
    <meta http-equiv="X-UA-Compatible" content="IE=edge" />

You can always wrap your promise returning functions in a way that they catches failure and returning instead an agreed value (e.g. error.message), so the exception won't roll all the way up to the Promise.all function and disable it.

async function resetCache(ip) {

    try {

        const response = await axios.get(`http://${ip}/resetcache`);
        return response;

    }catch (e) {

        return {status: 'failure', reason: 'e.message'};
    }

}

Complete case for vue 3

This is a complete solution based on MadisonTrash answer, and benrwb and fredrivett tweaks for safari compatibility and vue 3 api changes.

Edit:

The solution proposed below is still useful, and the how to use is still valid, but I changed it to use document.elementsFromPoint instead of event.contains because it doesn't recognise as children some elements like the <path> tags inside svgs. So the right directive is this one:

export default {
    beforeMount: (el, binding) => {
        el.eventSetDrag = () => {
            el.setAttribute("data-dragging", "yes");
        };
        el.eventClearDrag = () => {
            el.removeAttribute("data-dragging");
        };
        el.eventOnClick = event => {
            const dragging = el.getAttribute("data-dragging");
            // Check that the click was outside the el and its children, and wasn't a drag
            console.log(document.elementsFromPoint(event.clientX, event.clientY))
            if (!document.elementsFromPoint(event.clientX, event.clientY).includes(el) && !dragging) {
                // call method provided in attribute value
                binding.value(event);
            }
        };
        document.addEventListener("touchstart", el.eventClearDrag);
        document.addEventListener("touchmove", el.eventSetDrag);
        document.addEventListener("click", el.eventOnClick);
        document.addEventListener("touchend", el.eventOnClick);
    },
    unmounted: el => {
        document.removeEventListener("touchstart", el.eventClearDrag);
        document.removeEventListener("touchmove", el.eventSetDrag);
        document.removeEventListener("click", el.eventOnClick);
        document.removeEventListener("touchend", el.eventOnClick);
        el.removeAttribute("data-dragging");
    },
};

Old answer:

Directive

const clickOutside = {
    beforeMount: (el, binding) => {
        el.eventSetDrag = () => {
            el.setAttribute("data-dragging", "yes");
        };
        el.eventClearDrag = () => {
            el.removeAttribute("data-dragging");
        };
        el.eventOnClick = event => {
            const dragging = el.getAttribute("data-dragging");  
            // Check that the click was outside the el and its children, and wasn't a drag
            if (!(el == event.target || el.contains(event.target)) && !dragging) {
                // call method provided in attribute value
                binding.value(event);
            }
        };
        document.addEventListener("touchstart", el.eventClearDrag);
        document.addEventListener("touchmove", el.eventSetDrag);
        document.addEventListener("click", el.eventOnClick);
        document.addEventListener("touchend", el.eventOnClick);
    },
    unmounted: el => {
        document.removeEventListener("touchstart", el.eventClearDrag);
        document.removeEventListener("touchmove", el.eventSetDrag);
        document.removeEventListener("click", el.eventOnClick);
        document.removeEventListener("touchend", el.eventOnClick);
        el.removeAttribute("data-dragging");
    },
}

createApp(App)
  .directive("click-outside", clickOutside)
  .mount("#app");

This solution watch the element and the element's children of the component where the directive is applied to check if the event.target element is also a child. If that's the case it will not trigger, because it's inside the component.

How to use it

You only have to use as any directive, with a method reference to handle the trigger:

<template>
    <div v-click-outside="myMethod">
        <div class="handle" @click="doAnotherThing($event)">
            <div>Any content</div>
        </div>
    </div>
</template>

Removing hashCode() and equals() solved my issue. In my case, I used Apache's commons-lang hash code and equals builders for creating non-static classes manually, so the compiler didn't throw any exception. But at runtime it caused the invocation exception.

The ALL_DIRECTORIES data dictionary view will have information about all the directories that you have access to. That includes the operating system path

SELECT owner, directory_name, directory_path
  FROM all_directories

There is a third-party log4net adapter for the ASP.NET Core logging interface.

Only thing you need to do is pass the ILoggerFactory to your Startup class, then call

loggerFactory.AddLog4Net();

and have a config in place. So you don't have to write any boiler-plate code.

I found an other way to just get the base url to to display the value of environment variable APP_URL

env('APP_URL')

which will display the base url like http://domains_your//yours_website. beware it assumes that you had set the environment variable in .env file (that is present in the root folder).

1) Others (especially dirkgently) have noted that buffer needs to be allocated some memory space. For smallish values of N (say, N <= 4096), you can also allocate it on the stack:

#define BUFFER_SIZE 4096
char buffer[BUFFER_SIZE]

This saves you the worry of ensuring that you delete[] the buffer should an exception be thrown.

But remember that stacks are finite in size (so are heaps, but stacks are finiter), so you don't want to put too much there.

2) On a -1 return code, you should not simply return immediately (throwing an exception immediately is even more sketchy.) There are certain normal conditions that you need to handle, if your code is to be anything more than a short homework assignment. For example, EAGAIN may be returned in errno if no data is currently available on a non-blocking socket. Have a look at the man page for read(2).

curl performs SSL certificate verification by default, using a "bundle" of Certificate Authority (CA) public keys (CA certs). The default bundle is named curl-ca-bundle.crt; you can specify an alternate file using the --cacert option.

If this HTTPS server uses a certificate signed by a CA represented in the bundle, the certificate verification probably failed due to a problem with the certificate (it might be expired, or the name might not match the domain name in the URL).

If you'd like to turn off curl's verification of the certificate, use the -k (or --insecure) option.

for example

curl --insecure http://........

This is hard to answer without more detail about the network architecture. Some things to investigate are:

• Is it possible that client and/or server is behind a NAT device, a firewall, or similar?
• Is any of the IP addresses involved a "local" address, like 192.168.x.y or 10.x.y.z?
• What are the host names, are they "real" DNS:able names or something more local and/or Windows-specific?
• How does the client look up the server? There must be a place in code or config data that holds the host name, simply try using the IP there instead if you want to avoid the lookup.

You can use -

$isTouch = isset($variable);

It will return true if the $variable is defined. if the variable is not defined it will return false.

Note : Returns TRUE if var exists and has value other than NULL, FALSE otherwise.

If you want to check for false, 0 etc You can then use empty() -

$isTouch = empty($variable);

empty() works for -

• "" (an empty string)
• 0 (0 as an integer)
• 0.0 (0 as a float)
• "0" (0 as a string)
• NULL
• FALSE
• array() (an empty array)
• $var; (a variable declared, but without a value)

In C# it is not possible to call another constructor from inside the method body. You can call a base constructor this way: foo(args):base() as pointed out yourself. You can also call another constructor in the same class: foo(args):this().

When you want to do something before calling a base constructor, it seems the construction of the base is class is dependant of some external things. If so, you should through arguments of the base constructor, not by setting properties of the base class or something like that

OCTOBER 2016 UPDATE

With support library v25.0.0 there finally is a default implementation of basic horizontal and vertical dividers available!

https://developer.android.com/reference/android/support/v7/widget/DividerItemDecoration.html

I'd like to add that removing the Visual C++ 2012 Redistributable may be necessary, too. I removed both the Visual C++ 2012 Redistributable x84 and x64 and then my installation worked.

It's called the 'ternary' or 'conditional' operator.

Example

The ?: operator can be used as a shortcut for an if...else statement. It is typically used as part of a larger expression where an if...else statement would be awkward. For example:

var now = new Date();
var greeting = "Good" + ((now.getHours() > 17) ? " evening." : " day.");

The example creates a string containing "Good evening." if it is after 6pm. The equivalent code using an if...else statement would look as follows:

var now = new Date();
var greeting = "Good";
if (now.getHours() > 17)
   greeting += " evening.";
else
   greeting += " day.";

From MSDN JS documentation.

Basically it's a shorthand conditional statement.

Also see:

• Operator precedence with Javascript Ternary operator
• Wikipedia

A stack frame is a frame of data that gets pushed onto the stack. In the case of a call stack, a stack frame would represent a function call and its argument data.

If I remember correctly, the function return address is pushed onto the stack first, then the arguments and space for local variables. Together, they make the "frame," although this is likely architecture-dependent. The processor knows how many bytes are in each frame and moves the stack pointer accordingly as frames are pushed and popped off the stack.

EDIT:

There is a big difference between higher-level call stacks and the processor's call stack.

When we talk about a processor's call stack, we are talking about working with addresses and values at the byte/word level in assembly or machine code. There are "call stacks" when talking about higher-level languages, but they are a debugging/runtime tool managed by the runtime environment so that you can log what went wrong with your program (at a high level). At this level, things like line numbers and method and class names are often known. By the time the processor gets the code, it has absolutely no concept of these things.

You can use sys.exit() to exit from the middle of the main function.

However, I would recommend not doing any logic there. Instead, put everything in a function, and call that from __main__ - then you can use return as normal.

x[r,]

where r is the row you're interested in. Try this, for example:

#Add your data
x <- structure(list(A = c(5,    3.5, 3.25, 4.25,  1.5 ), 
                    B = c(4.25, 4,   4,    4.5,   4.5 ),
                    C = c(4.5,  2.5, 4,    2.25,  3   )
               ),
               .Names    = c("A", "B", "C"),
               class     = "data.frame",
               row.names = c(NA, -5L)
     )

#The vector your result should match
y<-c(A=5, B=4.25, C=4.5)

#Test that the items in the row match the vector you wanted
x[1,]==y

A bit late in the game but just in case it helps anyone.

If you are testing using the Sandbox and on the payment page you want to test payments NOT using a PayPal account but using the "Pay with Debit or Credit Card option" (i.e. when a regular Joe/Jane, NOT PayPal users, want to buy your stuff) and want to save yourself some time: just go to a site like http://www.getcreditcardnumbers.com/ and get numbers from there. You can use any Expiry date (in the future) and any numeric CCV (123 works).

The "test credit card numbers" in the PayPal documentation are just another brick in their infuriating wall of convoluted stuff.

I got the url above from PayPal's tech support.

Tested using a simple Hosted button and IPN. Good luck.

I have created some extension methods (below) so you don't have to worry if an IQueryable is already ordered or not. If you want to order by multiple properties just do it as follows:

// We do not have to care if the queryable is already sorted or not. 
// The order of the Smart* calls defines the order priority
queryable.SmartOrderBy(i => i.Property1).SmartOrderByDescending(i => i.Property2);

This is especially helpful if you create the ordering dynamically, f.e. from a list of properties to sort.

public static class IQueryableExtension
{
    public static bool IsOrdered<T>(this IQueryable<T> queryable) {
        if(queryable == null) {
            throw new ArgumentNullException("queryable");
        }

        return queryable.Expression.Type == typeof(IOrderedQueryable<T>);
    }

    public static IQueryable<T> SmartOrderBy<T, TKey>(this IQueryable<T> queryable, Expression<Func<T, TKey>> keySelector) {
        if(queryable.IsOrdered()) {
            var orderedQuery = queryable as IOrderedQueryable<T>;
            return orderedQuery.ThenBy(keySelector);
        } else {
            return queryable.OrderBy(keySelector);
        }
    }

    public static IQueryable<T> SmartOrderByDescending<T, TKey>(this IQueryable<T> queryable, Expression<Func<T, TKey>> keySelector) {
        if(queryable.IsOrdered()) {
            var orderedQuery = queryable as IOrderedQueryable<T>;
            return orderedQuery.ThenByDescending(keySelector);
        } else {
            return queryable.OrderByDescending(keySelector);
        }
    }
}

Try this

DateTime startTime = varValue
DateTime endTime = varTime

TimeSpan span = endTime.Subtract ( startTime );
Console.WriteLine( "Time Difference (minutes): " + span.TotalMinutes );

Edit: If are you trying 'span.Minutes', this will return only the minutes of timespan [0~59], to return sum of all minutes from this interval, just use 'span.TotalMinutes'.

As I stated in comment i would use a box layout for this.

JPanel panel = new JPanel();
panel.setLayout(new BoxLayout());

JButton button = new JButton("Button1");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

button = new JButton("Button2");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

button = new JButton("Button3");
button.setAlignmentX(Component.CENTER_ALIGNMENT);
panel.add(button);

add(panel);

I was not sure about the tests in OP. I decided to experiment a little and ended up busting some of the myths.

Synchronous <script src...> will block downloading of the resources below it until it is downloaded and executed

This is no longer true. Have a look at the waterfall generated by Chrome 63:

<head>
<script src="//alias-0.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=1"></script>
<script src="//alias-1.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=2"></script>
<script src="//alias-2.redacted.com/payload.php?type=js&amp;delay=333&amp;rand=3"></script>
</head>

<link rel=stylesheet> will not block download and execution of scripts below it

This is incorrect. The stylesheet will not block download but it will block execution of the script (little explanation here). Have a look at performance chart generated by Chrome 63:

<link href="//alias-0.redacted.com/payload.php?type=css&amp;delay=666" rel="stylesheet">
<script src="//alias-1.redacted.com/payload.php?type=js&amp;delay=333&amp;block=1000"></script>

Keeping the above in mind, the results in OP can be explained as follows:

I only found one way that worked...

$quote = $pdomodel->executeQuery("SELECT * FROM MyTable");

//if (!is_array($quote)) {  didn't work
//if (!isset($quote)) {  didn't work

if (count($quote) == 0) {   //yep the count worked.
    echo 'Record does not exist.';
    die;
}

All the other answers are correct, however, you might have problems if you're trying to check directory in a user's home directory. Make sure you expand the relative path before checking:

File.exists? '~/exists'
=> false
File.directory? '~/exists'
=> false
File.exists? File.expand_path('~/exists')
=> true

Create dictionaries for both arrays using _.keyBy(), merge the dictionaries, and convert the result to an array with _.values(). In this way, the order of the arrays doesn't matter. In addition, it can also handle arrays of different length.

const ObjectId = (id) => id; // mock of ObjectId_x000D_
const arr1 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")}];_x000D_
const arr2 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"name" : 'xxxxxx',"age" : 25},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"name" : 'yyyyyyyyyy',"age" : 26}];_x000D_
_x000D_
const merged = _(arr1) // start sequence_x000D_
  .keyBy('member') // create a dictionary of the 1st array_x000D_
  .merge(_.keyBy(arr2, 'member')) // create a dictionary of the 2nd array, and merge it to the 1st_x000D_
  .values() // turn the combined dictionary to array_x000D_
  .value(); // get the value (array) out of the sequence_x000D_
_x000D_
console.log(merged);

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.14.0/lodash.min.js"></script>

Using ES6 Map

Concat the arrays, and reduce the combined array to a Map. Use Object#assign to combine objects with the same member to a new object, and store in map. Convert the map to an array with Map#values and spread:

const ObjectId = (id) => id; // mock of ObjectId_x000D_
const arr1 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"bank" : ObjectId("575b052ca6f66a5732749ecc"),"country" : ObjectId("575b0523a6f66a5732749ecb")}];_x000D_
const arr2 = [{"member" : ObjectId("57989cbe54cf5d2ce83ff9d6"),"name" : 'xxxxxx',"age" : 25},{"member" : ObjectId("57989cbe54cf5d2ce83ff9d8"),"name" : 'yyyyyyyyyy',"age" : 26}];_x000D_
_x000D_
const merged = [...arr1.concat(arr2).reduce((m, o) => _x000D_

There is a great library used to manipulate dates: Delorean

import datetime
from delorean import Delorean
now = datetime.datetime.now()
d = Delorean(now, timezone='US/Pacific')

>>> now    
datetime.datetime(2015, 3, 26, 19, 46, 40, 525703)

>>> d.truncate('second')
Delorean(datetime=2015-03-26 19:46:40-07:00, timezone='US/Pacific')

>>> d.truncate('minute')
Delorean(datetime=2015-03-26 19:46:00-07:00, timezone='US/Pacific')

>>> d.truncate('hour')
Delorean(datetime=2015-03-26 19:00:00-07:00, timezone='US/Pacific')

>>> d.truncate('day')
Delorean(datetime=2015-03-26 00:00:00-07:00, timezone='US/Pacific')

>>> d.truncate('month')
Delorean(datetime=2015-03-01 00:00:00-07:00, timezone='US/Pacific')

>>> d.truncate('year')
Delorean(datetime=2015-01-01 00:00:00-07:00, timezone='US/Pacific')

and if you want to get datetime value back:

>>> d.truncate('year').datetime
datetime.datetime(2015, 1, 1, 0, 0, tzinfo=<DstTzInfo 'US/Pacific' PDT-1 day, 17:00:00 DST>)

Try changing the build target platform to x86 and building the project.

I noticed via Subversion that I apparently changed the project build Platform target to x64. This was the only change I had made. After making that change, the code was working for a short while before it started showing the same error you experienced. I changed the platform target to x86 to test and suddenly my designer was working again. Subsequently, I changed it back to x64, and the problem has disappeared completely. I suspect that the designer builds some kind of cached code in x32 and changing the x64 build platform breaks it when you make code changes.

It's HTML character references for encoding a character by its decimal code point

Look at the ASCII table here and you'll see that 39 (hex 0x27, octal 47) is the code for apostrophe

UPDATE

While these methods work, newer versions of VS Code uses the Ctrl+] shortcut to indent a block of code once, and Ctrl+[ to remove indentation.

This method detects the indentation in a file and indents accordingly.You can change the size of indentation by clicking on the Select Indentation setting in the bottom right of VS Code (looks something like "Spaces: 2"), selecting "Indent using Spaces" from the drop-down menu and then selecting by how many spaces you would like to indent.

There are a couple ways you can do this. The most efficient way would be to use URL.createObjectURL() on the File from your <input>. Pass this URL to img.src to tell the browser to load the provided image.

Here's an example:

<input type="file" accept="image/*" onchange="loadFile(event)">_x000D_
<img id="output"/>_x000D_
<script>_x000D_
  var loadFile = function(event) {_x000D_
    var output = document.getElementById('output');_x000D_
    output.src = URL.createObjectURL(event.target.files[0]);_x000D_
    output.onload = function() {_x000D_
      URL.revokeObjectURL(output.src) // free memory_x000D_
    }_x000D_
  };_x000D_
</script>

You can also use FileReader.readAsDataURL() to parse the file from your <input>. This will create a string in memory containing a base64 representation of the image.

<input type="file" accept="image/*" onchange="loadFile(event)">_x000D_
<img id="output"/>_x000D_
<script>_x000D_
  var loadFile = function(event) {_x000D_
    var reader = new FileReader();_x000D_
    reader.onload = function(){_x000D_
      var output = document.getElementById('output');_x000D_
      output.src = reader.result;_x000D_
    };_x000D_
    reader.readAsDataURL(event.target.files[0]);_x000D_
  };_x000D_
</script>

Make sure that your log4j is configured correctly, there's probably an exception that is being thrown, but you're only seeing half of the picture.

Please see https://stackoverflow.com/a/16817018/1249304

In my experience, regex solutions have too many false positives and filter_var() solutions have false negatives (especially with all of the newer TLDs).

Instead, it's better to make sure the address has all of the required parts of an email address (user, "@" symbol, and domain), then verify that the domain itself exists.

There is no way to determine (server side) if an email user exists for an external domain.

This is a method I created in a Utility class:

public static function validateEmail($email)
{
    // SET INITIAL RETURN VARIABLES

        $emailIsValid = FALSE;

    // MAKE SURE AN EMPTY STRING WASN'T PASSED

        if (!empty($email))
        {
            // GET EMAIL PARTS

                $domain = ltrim(stristr($email, '@'), '@') . '.';
                $user   = stristr($email, '@', TRUE);

            // VALIDATE EMAIL ADDRESS

                if
                (
                    !empty($user) &&
                    !empty($domain) &&
                    checkdnsrr($domain)
                )
                {$emailIsValid = TRUE;}
        }

    // RETURN RESULT

        return $emailIsValid;
}

You can try to use btn-sm, btn-xs and btn-lg classes like this:

.btn-xl {
    padding: 10px 20px;
    font-size: 20px;
    border-radius: 10px;
}

JSFIDDLE DEMO

You can make use of Bootstrap .btn-group-justified css class. Or you can simply add:

.btn-xl {
    padding: 10px 20px;
    font-size: 20px;
    border-radius: 10px;
    width:50%;    //Specify your width here
}

JSFIDDLE DEMO

This is an old post but regardless, you can also get boldface and italic characters by leveraging utf-32. There are even greek and math symbols that can be used as well as the roman alphabet.

For me it was an issue with deviceToken. Please check if the receiver and sender device token is properly updated in your database or wherever you are accessing it to send notifications.

For instance, use the following to update the device token on app launch. Therefore it will be always updated properly.

// Device token for push notifications
FirebaseInstanceId.getInstance().getInstanceId().addOnSuccessListener(
  new OnSuccessListener<InstanceIdResult>() {

    @Override
    public void onSuccess(InstanceIdResult instanceIdResult) {

        deviceToken = instanceIdResult.getToken();

        // Insert device token into Firebase database
        fbDbRefRoot.child("user_detail_profile").child(currentUserId).child("device_token")).setValue(deviceToken)
                .addOnSuccessListener(
                  new OnSuccessListener<Void>() {

                    @Override
                    public void onSuccess(Void aVoid) {

                    }
                });
    }
});

fs/promises and fs.Dirent

Here's an efficient, non-blocking ls program using Node's fast fs.Dirent objects and fs/promises module. This approach allows you to skip wasteful fs.exist or fs.stat calls on every path -

// main.js
import { readdir } from "fs/promises"
import { join } from "path"

async function* ls (path = ".")
{ yield path
  for (const dirent of await readdir(path, { withFileTypes: true }))
    if (dirent.isDirectory())
      yield* ls(join(path, dirent.name))
    else
      yield join(path, dirent.name)
}

async function* empty () {}

async function toArray (iter = empty())
{ let r = []
  for await (const x of iter)
    r.push(x)
  return r
}

toArray(ls(".")).then(console.log, console.error)

Let's get some sample files so we can see ls working -

$ yarn add immutable     # (just some example package)
$ node main.js

[
  '.',
  'main.js',
  'node_modules',
  'node_modules/.yarn-integrity',

- (void)viewDidLoad
{
   [self.tableView setSeparatorColor:[UIColor myColor]];
}

I hope that helps - you'll need the self. to access it, remember.

Swift 4.2

tableView.separatorColor = UIColor.red

Try using replaceWith() or replaceAll()

The way via unlist and matrix seems a bit convoluted, and requires you to hard-code the number of elements (this is actually a pretty big no-go. Of course you could circumvent hard-coding that number and determine it at run-time)

I would go a different route, and construct a data frame directly from the list that strsplit returns. For me, this is conceptually simpler. There are essentially two ways of doing this:

1. as.data.frame – but since the list is exactly the wrong way round (we have a list of rows rather than a list of columns) we have to transpose the result. We also clear the rownames since they are ugly by default (but that’s strictly unnecessary!):

   `rownames<-`(t(as.data.frame(strsplit(text, '\\.'))), NULL)
   

2. Alternatively, use rbind to construct a data frame from the list of rows. We use do.call to call rbind with all the rows as separate arguments:

   do.call(rbind, strsplit(text, '\\.'))
   

Both ways yield the same result:

     [,1] [,2] [,3]  [,4]
[1,] "F"  "US" "CLE" "V13"
[2,] "F"  "US" "CA6" "U13"
[3,] "F"  "US" "CA6" "U13"
[4,] "F"  "US" "CA6" "U13"
[5,] "F"  "US" "CA6" "U13"
[6,] "F"  "US" "CA6" "U13"
…

Clearly, the second way is much simpler than the first.

Thank you

if you are using extracted tomcat then,

startup.sh and shutdown.sh are two script located in TOMCAT/bin/ to start and shutdown tomcat, You could use that

if tomcat is installed then

/etc/init.d/tomcat5.5 start
/etc/init.d/tomcat5.5 stop
/etc/init.d/tomcat5.5 restart

Great question!

There are many websites and free web apps implemented in PHP that run on Apache, lots of people use it so you can mash up something pretty easy and besides, its a no-brainer way of serving static content. Node is fast, powerful, elegant, and a sexy tool with the raw power of V8 and a flat stack with no in-built dependencies.

I also want the ease/flexibility of Apache and yet the grunt and elegance of Node.JS, why can't I have both?

Fortunately with the ProxyPass directive in the Apache httpd.conf its not too hard to pipe all requests on a particular URL to your Node.JS application.

ProxyPass /node http://localhost:8000

Also, make sure the following lines are NOT commented out so you get the right proxy and submodule to reroute http requests:

LoadModule proxy_module modules/mod_proxy.so
LoadModule proxy_http_module modules/mod_proxy_http.so

Then run your Node app on port 8000!

var http = require('http');
http.createServer(function (req, res) {
  res.writeHead(200, {'Content-Type': 'text/plain'});
  res.end('Hello Apache!\n');
}).listen(8000, '127.0.0.1');

Then you can access all Node.JS logic using the /node/ path on your url, the rest of the website can be left to Apache to host your existing PHP pages:

Now the only thing left is convincing your hosting company let your run with this configuration!!!

This is because of using integer indices (ix selects those by label over -3 rather than position, and this is by design: see integer indexing in pandas "gotchas"*).

*In newer versions of pandas prefer loc or iloc to remove the ambiguity of ix as position or label:

df.iloc[-3:]

see the docs.

As Wes points out, in this specific case you should just use tail!

I found the answer here:
https://web.archive.org/web/20160421163524/http://vijayt.com/Post/Set-RadioButton-value-using-jQuery

Basically, if you want to check one radio button, you MUST pass the value as an array:

$('input:radio[name=cols]').val(['Site']);
$('input:radio[name=rows]').val(['Site']);

I'd use recursion just in case so you can deep copy the map and avoid bad surprises in case you were to change a map element that is a map itself.

Here's an example in a utils.go:

package utils

func CopyMap(m map[string]interface{}) map[string]interface{} {
    cp := make(map[string]interface{})
    for k, v := range m {
        vm, ok := v.(map[string]interface{})
        if ok {
            cp[k] = CopyMap(vm)
        } else {
            cp[k] = v
        }
    }

    return cp
}

And its test file (i.e. utils_test.go):

package utils

import (
    "testing"

    "github.com/stretchr/testify/require"
)

func TestCopyMap(t *testing.T) {
    m1 := map[string]interface{}{
        "a": "bbb",
        "b": map[string]interface{}{
            "c": 123,
        },
    }

    m2 := CopyMap(m1)

    m1["a"] = "zzz"
    delete(m1, "b")

    require.Equal(t, map[string]interface{}{"a": "zzz"}, m1)
    require.Equal(t, map[string]interface{}{
        "a": "bbb",
        "b": map[string]interface{}{
            "c": 123,
        },
    }, m2)
}

It should easy enough to adapt if you need the map key to be something else instead of a string.

You should try this. It starts the program with no window. It actually flashes up for a second but goes away fairly quickly.

start "name" /B myprogram.exe param1

size_t ln = strlen(name) - 1;
if (*name && name[ln] == '\n') 
    name[ln] = '\0';

Using Woodstox, configure the StAX parser to validate against your schema and parse the XML.

If exceptions are caught the XML is not valid, otherwise it is valid:

// create the XSD schema from your schema file
XMLValidationSchemaFactory schemaFactory = XMLValidationSchemaFactory.newInstance(XMLValidationSchema.SCHEMA_ID_W3C_SCHEMA);
XMLValidationSchema validationSchema = schemaFactory.createSchema(schemaInputStream);

// create the XML reader for your XML file
WstxInputFactory inputFactory = new WstxInputFactory();
XMLStreamReader2 xmlReader = (XMLStreamReader2) inputFactory.createXMLStreamReader(xmlInputStream);

try {
    // configure the reader to validate against the schema
    xmlReader.validateAgainst(validationSchema);

    // parse the XML
    while (xmlReader.hasNext()) {
        xmlReader.next();
    }

    // no exceptions, the XML is valid

} catch (XMLStreamException e) {

    // exceptions, the XML is not valid

} finally {
    xmlReader.close();
}

Note: If you need to validate multiple files, you should try to reuse your XMLInputFactory and XMLValidationSchema in order to maximize the performance.

Dead easy solution, ws and port, tested:

var ws = new WebSocket("ws://" + window.location.host + ":6666");

ws.onopen = function() { ws.send( .. etc

abc "$@"

$@ represents all the parameters given to your bash script.

You can't do pointer arithmetic on void * types, for exactly this reason!

Appreciate answered by Sid because its dynamic but I want to add something.

What if you want to change width only, height will be as it is.

I have done like following:

    // All process of AlertDialog
    AlertDialog alert = builder.create();
    alert.show();

    // Creating Dynamic
    Rect displayRectangle = new Rect();

    Window window = getActivity().getWindow();
    window.getDecorView().getWindowVisibleDisplayFrame(displayRectangle);
    alert.getWindow().setLayout((int) (displayRectangle.width() *
            0.8f), alert.getWindow().getAttributes().height);

Here I used alert.getWindow().getAttributes().height to keep height as it is of AlertDialog and Width will be changed as per screen resolution.

Hope it will helps. Thanks.

I too got similar error when i misplaced the code

text=(TextView)findViewById(R.id.text);// this line has to be below setcontentview
setContentView(R.layout.activity_my_otype);
//this is the correct place
text.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            }
    });

I got it working on placing the code in right order as shown below

setContentView(R.layout.activity_my_otype);
text=(TextView)findViewById(R.id.text);
 text.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View view) {
            }
    });

if(isnull({uspRptMonthlyGasRevenueByGas;1.YearTotal})) = true then
   "nd"
else
    totext({uspRptMonthlyGasRevenueByGas;1.YearTotal},'###.00')

The above logic should be what you are looking for.

@GET
@Path("/friends")
@Produces(MediaType.APPLICATION_JSON)
public String getFriends() {

    // here you can return any bean also it will automatically convert into json 
    return "{'friends': ['Michael', 'Tom', 'Daniel', 'John', 'Nick']}";
}

One addendum to the excellent answers above, on a point that confused me even after I had read Stroustrup and thought I understood the rvalue/lvalue distinction. When you see

int&& a = 3,

it's very tempting to read the int&& as a type and conclude that a is an rvalue. It's not:

int&& a = 3;
int&& c = a; //error: cannot bind 'int' lvalue to 'int&&'
int& b = a; //compiles

a has a name and is ipso facto an lvalue. Don't think of the && as part of the type of a; it's just something telling you what a is allowed to bind to.

This matters particularly for T&& type arguments in constructors. If you write

Foo::Foo(T&& _t) : t{_t} {}

you will copy _t into t. You need

Foo::Foo(T&& _t) : t{std::move(_t)} {} if you want to move. Would that my compiler warned me when I left out the move!

Here is an implementation of a delete cookie function with unicode support from Mozilla:

function removeItem(sKey, sPath, sDomain) {
    document.cookie = encodeURIComponent(sKey) + 
                  "=; expires=Thu, 01 Jan 1970 00:00:00 GMT" + 
                  (sDomain ? "; domain=" + sDomain : "") + 
                  (sPath ? "; path=" + sPath : "");
}

removeItem("cookieName");

If you use AngularJs, try $cookies.remove (underneath it uses a similar approach):

$cookies.remove('cookieName');

WITH CHECK CHECK is almost certainly required!

This point was raised in some of the answers and comments but I feel that it is important enough to call it out again.

Re-enabling a constraint using the following command (no WITH CHECK) will have some serious drawbacks.

ALTER TABLE MyTable CHECK CONSTRAINT MyConstraint;

WITH CHECK | WITH NOCHECK

Specifies whether the data in the table is or is not validated against a newly added or re-enabled FOREIGN KEY or CHECK constraint. If not specified, WITH CHECK is assumed for new constraints, and WITH NOCHECK is assumed for re-enabled constraints.

If you do not want to verify new CHECK or FOREIGN KEY constraints against existing data, use WITH NOCHECK. We do not recommend doing this, except in rare cases. The new constraint will be evaluated in all later data updates. Any constraint violations that are suppressed by WITH NOCHECK when the constraint is added may cause future updates to fail if they update rows with data that does not comply with the constraint.

The query optimizer does not consider constraints that are defined WITH NOCHECK. Such constraints are ignored until they are re-enabled by using ALTER TABLE table WITH CHECK CHECK CONSTRAINT ALL.

Note: WITH NOCHECK is the default for re-enabling constraints. I have to wonder why...

1. No existing data in the table will be evaluated during the execution of this command - successful completion is no guarantee that the data in the table is valid according to the constraint.
2. During the next update of the invalid records, the constraint will be evaluated and will fail - resulting in errors that may be unrelated to the actual update that is made.
3. Application logic that relies on the constraint to ensure that data is valid may fail.
4. The query optimizer will not make use of any constraint that is enabled in this way.

The sys.foreign_keys system view provides some visibility into the issue. Note that it has both an is_disabled and an is_not_trusted column. is_disabled indicates whether future data manipulation operations will be validated against the constraint. is_not_trusted indicates whether all of the data currently in the table has been validated against the constraint.

ALTER TABLE MyTable WITH CHECK CHECK CONSTRAINT MyConstraint;

Are your constraints to be trusted? Find out...

SELECT * FROM sys.foreign_keys WHERE is_not_trusted = 1;

This problem arises when you have composer installed locally. To make it globally executable,run the below command in terminal

sudo mv composer.phar /usr/local/bin/composer

For CentOS 7 the command is

sudo mv composer.phar /usr/bin/composer

std::sort(str.begin(), str.end());

See here

Install the termcolor module

sudo pip install termcolor

and then try this for colored text

from termcolor import colored
print colored('Hello', 'green')

or this for bold text:

from termcolor import colored
print colored('Hello', attrs=['bold'])

In Python 3 you can alternatively use cprint as a drop-in replacement for the built-in print, with the optional second parameter for colors or the attrs parameter for bold (and other attributes such as underline) in addition to the normal named print arguments such as file or end.

import sys
from termcolor import cprint
cprint('Hello', 'green', attrs=['bold'], file=sys.stderr)

Full disclosure, this answer is heavily based on Olu Smith's answer and was intended as an edit, which would have reduced the noise on this page considerably but because of some reviewers' misguided concept of what an edit is supposed to be, I am now forced to make this a separate answer.

A useful application for : is if you're only interested in using parameter expansions for their side-effects rather than actually passing their result to a command. In that case you use the PE as an argument to either : or false depending upon whether you want an exit status of 0 or 1. An example might be : "${var:=$1}". Since : is a builtin it should be pretty fast.

This is really a tricky thing to have a sticky header on your table. I had same requirement but with asp:GridView and then I found it really thought to have sticky header on gridview. There are many solutions available and it took me 3 days trying all the solution but none of them could satisfy.

The main issue that I faced with most of these solutions was the alignment problem. When you try to make the header floating, somehow the alignment of header cells and body cells get off track.

With some solutions, I also got issue of getting header overlapped to first few rows of body, which cause body rows getting hidden behind the floating header.

So now I had to implement my own logic to achieve this, though I also not consider this as perfect solution but this could also be helpful for someone,

Below is the sample table.

<div class="table-holder">
        <table id="MyTable" cellpadding="4" cellspacing="0" border="1px" class="customerTable">
            <thead>
                <tr><th>ID</th><th>First Name</th><th>Last Name</th><th>DOB</th><th>Place</th></tr>
            </thead>
            <tbody>
                <tr><td>1</td><td>Customer1</td><td>LastName</td><td>1-1-1</td><td>SUN</td></tr>
                <tr><td>2</td><td>Customer2</td><td>LastName</td><td>2-2-2</td><td>Earth</td></tr>
                <tr><td>3</td><td>Customer3</td><td>LastName</td><td>3-3-3</td><td>Mars</td></tr>
                <tr><td>4</td><td>Customer4</td><td>LastName</td><td>4-4-4</td><td>Venus</td></tr>
                <tr><td>5</td><td>Customer5</td><td>LastName</td><td>5-5-5</td><td>Saturn</td></tr>
                <tr><td>6</td><td>Customer6</td><td>LastName</td><td>6-6-6</td><td>Jupitor</td></tr>
                <tr><td>7</td><td>Customer7</td><td>LastName</td><td>7-7-7</td><td>Mercury</td></tr>
                <tr><td>8</td><td>Customer8</td><td>LastName</td><td>8-8-8</td><td>Moon</td></tr>
                <tr><td>9</td><td>Customer9</td><td>LastName</td><td>9-9-9</td><td>Uranus</td></tr>
                <tr><td>10</td><td>Customer10</td><td>LastName</td><td>10-10-10</td><td>Neptune</td></tr>
            </tbody>
        </table>
    </div>

Note: The table is wrapped into a DIV with class attribute equal to 'table-holder'.

Below is the JQuery script that I added in my html page header.

<script src="../Scripts/jquery-1.7.2.min.js" type="text/javascript"></script>
<script src="../Scripts/jquery-ui.min.js" type="text/javascript"></script>
<script type="text/javascript">
    $(document).ready(function () {
        //create var for table holder
        var originalTableHolder = $(".table-holder");
        // set the table holder's with
        originalTableHolder.width($('table', originalTableHolder).width() + 17);
        // Create a clone of table holder DIV
        var clonedtableHolder = originalTableHolder.clone();

        // Calculate height of all header rows.
        var headerHeight = 0;
        $('thead', originalTableHolder).each(function (index, element) {
            headerHeight = headerHeight + $(element).height();
        });

        // Set the position of cloned table so that cloned table overlapped the original
        clonedtableHolder.css('position', 'relative');
        clonedtableHolder.css('top', headerHeight + 'px');

        // Set the height of cloned header equal to header height only so that body is not visible of cloned header
        clonedtableHolder.height(headerHeight);
        clonedtableHolder.css('overflow', 'hidden');

        // reset the ID attribute of each element in cloned table
        $('*', clonedtableHolder).each(function (index, element) {
            if ($(element).attr('id')) {
                $(element).attr('id', $(element).attr('id') + '_Cloned');
            }
        });

        originalTableHolder.css('border-bottom', '1px solid #aaa');

        // Place the cloned table holder before original one
        originalTableHolder.before(clonedtableHolder);
    });
</script>

and at last below is the CSS class for bit of coloring purpose.

.table-holder
{
    height:200px;
    overflow:auto;
    border-width:0px;    
}

.customerTable thead
{
    background: #4b6c9e;        
    color:White;
}

So the whole idea of this logic is to place the table into a table holder div and create clone of that holder at client side when page loaded. Now hide the body of table inside clone holder and position the remaining header part over to original header.

Same solution also works for asp:gridview, you need to add two more steps to achieve this in gridview,

1. In OnPrerender event of gridview object in your web page, set the table section of header row equal to TableHeader.

   if (this.HeaderRow != null)
   {
       this.HeaderRow.TableSection = TableRowSection.TableHeader;
   }
   

2. And wrap your grid into <div class="table-holder"></div>.

Note: if your header has clickable controls then you may need to add some more jQuery script to pass the events raised in cloned header to original header. This code is already available in jQuery sticky-header plugin create by jmosbech

You can do it the OO way, just an alternative and flexible:

class Logger {

    private
        $file,
        $timestamp;

    public function __construct($filename) {
        $this->file = $filename;
    }

    public function setTimestamp($format) {
        $this->timestamp = date($format)." » ";
    }

    public function putLog($insert) {
        if (isset($this->timestamp)) {
            file_put_contents($this->file, $this->timestamp.$insert."<br>", FILE_APPEND);
        } else {
            trigger_error("Timestamp not set", E_USER_ERROR);
        }
    }

    public function getLog() {
        $content = @file_get_contents($this->file);
        return $content;
    }

}

Then use it like this .. let's say you have user_name stored in a session (semi pseudo code):

$log = new Logger("log.txt");
$log->setTimestamp("D M d 'y h.i A");

if (user logs in) {
    $log->putLog("Successful Login: ".$_SESSION["user_name"]);
}
if (user logs out) {
    $log->putLog("Logout: ".$_SESSION["user_name"]);
}

Check your log with this:

$log->getLog();

Result is like:

Sun Jul 02 '17 05.45 PM » Successful Login: JohnDoe
Sun Jul 02 '17 05.46 PM » Logout: JohnDoe

According to Firebase docs you can also use string resources instead of google-services.json.

Because this provider is just reading resources with known names, another option is to add the string resources directly to your app instead of using the Google Services gradle plugin. You can do this by:

• Removing the google-services plugin from your root build.gradle
• Deleting the google-services.json from your project
• Adding the string resources directly
• Deleting apply plugin: 'com.google.gms.google-services' from your app build.gradle

Example strings.xml:

<string name="google_client_id">XXXXXXXXX.apps.googleusercontent.com</string>
<string name="default_web_client_id">XXXX-XXXXXX.apps.googleusercontent.com</string>
<string name="gcm_defaultSenderId">XXXXXX</string>
<string name="google_api_key">AIzaXXXXXX</string>
<string name="google_app_id">1:XXXXXX:android:XXXXX</string>
<string name="google_crash_reporting_api_key">AIzaXXXXXXX</string>
<string name="project_id">XXXXXXX</string>

There are a couple of different ways to approach the problem:

1. Wrap command-line programs
2. use a Python library that provides SSH capabilities (eg - Paramiko or Twisted Conch)

Each approach has its own quirks. You will need to setup SSH keys to enable password-less logins if you are wrapping system commands like "ssh", "scp" or "rsync." You can embed a password in a script using Paramiko or some other library, but you might find the lack of documentation frustrating, especially if you are not familiar with the basics of the SSH connection (eg - key exchanges, agents, etc). It probably goes without saying that SSH keys are almost always a better idea than passwords for this sort of stuff.

NOTE: its hard to beat rsync if you plan on transferring files via SSH, especially if the alternative is plain old scp.

I've used Paramiko with an eye towards replacing system calls but found myself drawn back to the wrapped commands due to their ease of use and immediate familiarity. You might be different. I gave Conch the once-over some time ago but it didn't appeal to me.

If opting for the system-call path, Python offers an array of options such as os.system or the commands/subprocess modules. I'd go with the subprocess module if using version 2.4+.

Date has the time as well, just add HH:mm:ss to the date format:

import java.text.SimpleDateFormat
def date = new Date()
def sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss")
println sdf.format(date)

In case you are using JRE 8 you can use LoaclDateTime:

import java.time.*

LocalDateTime t = LocalDateTime.now();
return t as String

You can connect your XML schema to Microsoft Visual Studio's Intellisense. This option gives you both real-time validation AND autocomplete, which is just awesome.

I have this exact scenario running on my free copy of Microsoft Visual C++ 2010 Express.

I think this solution uses less code and is easy to understand even for newbie.

For string field in struct, you can use pointer and reassigning the string to that pointer will be straightforward and simpler.

Define definition of struct:

typedef struct {
  int number;
  char *name;
  char *address;
  char *birthdate;
  char gender;
} Patient;

Initialize variable with type of that struct:

Patient patient;
patient.number = 12345;
patient.address = "123/123 some road Rd.";
patient.birthdate = "2020/12/12";
patient.gender = "M";

It is that simple. Hope this answer helps many developers.

The necessary method is Mockito#verify:

public static <T> T verify(T mock,
                           VerificationMode mode)

mock is your mocked object and mode is the VerificationMode that describes how the mock should be verified. Possible modes are:

verify(mock, times(5)).someMethod("was called five times");
verify(mock, never()).someMethod("was never called");
verify(mock, atLeastOnce()).someMethod("was called at least once");
verify(mock, atLeast(2)).someMethod("was called at least twice");
verify(mock, atMost(3)).someMethod("was called at most 3 times");
verify(mock, atLeast(0)).someMethod("was called any number of times"); // useful with captors
verify(mock, only()).someMethod("no other method has been called on the mock");

You'll need these static imports from the Mockito class in order to use the verify method and these verification modes:

import static org.mockito.Mockito.atLeast;
import static org.mockito.Mockito.atLeastOnce;
import static org.mockito.Mockito.atMost;
import static org.mockito.Mockito.never;
import static org.mockito.Mockito.only;
import static org.mockito.Mockito.times;
import static org.mockito.Mockito.verify;

So in your case the correct syntax will be:

Mockito.verify(mock, times(4)).send()

This verifies that the method send was called 4 times on the mocked object. It will fail if it was called less or more than 4 times.

If you just want to check, if the method has been called once, then you don't need to pass a VerificationMode. A simple

verify(mock).someMethod("was called once");

would be enough. It internally uses verify(mock, times(1)).someMethod("was called once");.

It is possible to have multiple verification calls on the same mock to achieve a "between" verification. Mockito doesn't support something like this verify(mock, between(4,6)).someMethod("was called between 4 and 6 times");, but we can write

verify(mock, atLeast(4)).someMethod("was called at least four times ...");
verify(mock, atMost(6)).someMethod("... and not more than six times");

instead, to get the same behaviour. The bounds are included, so the test case is green when the method was called 4, 5 or 6 times.

Python code:

try:
    # do my automated tasks
except:
    pass
finally:
    driver.close()
    driver.quit()

When using +, the speed decreases as the string's length increases, but when using concat, the speed is more stable, and the best option is using the StringBuilder class which has stable speed in order to do that.

I guess you can understand why. But the totally best way for creating long strings is using StringBuilder() and append(), either speed will be unacceptable.

This was a major problem for me and I found the following link with a relatively simple answer. Thanks Voyager!!!

Note that I named the range I wanted others to be able to sort

• Unprotect worksheet
• Go to "Protection"--- "Allow Users to Edit Ranges" (if Excel 2007, "Review" tab)
• Add "New" range
• Select the range you want allow users to sort
• Click "Protect Sheet"
• This time, *do not allow users to select "locked cells"**
• OK

I think the easiest workaround would be to use 'select' with 'multiple' specified:

<select ng-model="selectedfruit" multiple ng-options="v for v in fruit"></select>

Otherwise, I think you'll have to process the list to construct the list (by $watch()ing the model array bind with checkboxes).
