This code snippet is very easy to calculate business day without week end and holidays:

function getWorkingDays($startDate,$endDate,$offdays,$holidays){
$endDate = strtotime($endDate);
$startDate = strtotime($startDate);
$days = ($endDate - $startDate) / 86400 + 1;
$counter=0;
for ($i = 1; $i <= $days; $i++) {
    $the_first_day_of_week = date("N", $startDate);
    $startDate+=86400;
if (!in_array($the_first_day_of_week, $offdays) && !in_array(date("Y-m-
d",$startDate), $holidays)) {
$counter++;
}

}   
return $counter;
}
//example to use
$holidays=array("2017-07-03","2017-07-20");
$offdays=array(5,6);//weekend days Monday=1 .... Sunday=7
echo getWorkingDays("2017-01-01","2017-12-31",$offdays,$holidays)

Change the profiles parameter to "commandline": "%PROGRAMFILES%\\Git\\bin\\bash.exe -l -i"

This works for me and allows for my .bash_profile alias autocomplete scripts to run.

If what you want is the total number of records in the table appended to each row you can do something like

SELECT *
  FROM my_table
  CROSS JOIN (SELECT COUNT(*) AS COUNT_OF_RECS_IN_MY_TABLE
                FROM MY_TABLE)

STATEMENT:

A Statement is a action or a command that does something. Ex: If-Else,Loops..etc

val a: Int = 5
If(a>5) print("Hey!") else print("Hi!")

EXPRESSION:

A Expression is a combination of values, operators and literals which yields something.

val a: Int = 5 + 5 #yields 10

You need a reference to the class that contains the method you want to call. Let's say we have two classes, A and B. B has a method you want to call from A. Class A would look like this:

public class A
{
    B b; // A reference to B

    b = new B(); // Creating object of class B

    b.doSomething();  // Calling a method contained in class B from class A
}

B, which contains the doSomething() method would look like this:

public class B
{
    public void doSomething()
    {
        System.out.println("Look, I'm doing something in class B!");
    }
}

You should use the exit keyword.

I was getting this error when I was trying to add gestureRecognizer to my ViewController's view and the target was view, instead of being self:

Instead of:

self.view.addGestureRecognizer(UITapGestureRecognizer(target: self.view, action: #selector(handleTap(_:))))

Fixed to:

self.view.addGestureRecognizer(UITapGestureRecognizer(target: self, action: #selector(handleTap(_:))))

And the error was gone.

If you are using Outlook 2010, you can define your own style and select your formatting you want, in the Format options there is one option for Language, here you can specify the language and specify whether you want spell checker to ignore the text with this style.

With this style you can now paste the code as text and select your new style. Outlook will not correct the text and will not perform the spell check on it.

Below is the summary of the style I have defined for emailing the code snippets.

Do not check spelling or grammar, Border:
Box: (Single solid line, Orange,  0.5 pt Line width)
Pattern: Clear (Custom Color(RGB(253,253,217))), Style: Linked, Automatically update, Quick Style

JEP 354: Switch Expressions (Preview) in JDK-13 and JEP 361: Switch Expressions (Standard) in JDK-14 will extend the switch statement so it can be used as an expression.

Now you can:

• directly assign variable from switch expression,
• use new form of switch label (case L ->):

  The code to the right of a "case L ->" switch label is restricted to be an expression, a block, or (for convenience) a throw statement.

• use multiple constants per case, separated by commas,
• and also there are no more value breaks:

  To yield a value from a switch expression, the break with value statement is dropped in favor of a yield statement.

So the demo from the answers (1, 2) might look like this:

  public static void main(String[] args) {
    switch (args[0]) {
      case "Monday", "Tuesday", "Wednesday" ->  System.out.println("boring");
      case "Thursday" -> System.out.println("getting better");
      case "Friday", "Saturday", "Sunday" -> System.out.println("much better");
    }

You can do something like this, where you set a negative margin on the h1 (or whatever header you are using)

div{
    height:100px;
    width:100px;
    border:2px solid black;
}

h1{
    width:30px;
    margin-top:-10px;
    margin-left:5px;
    background:white;
}

Note: you need to set a background as well as a width on the h1

Example: http://jsfiddle.net/ZgEMM/

EDIT

To make it work with hiding the div, you could use some jQuery like this

$('a').click(function(){
    var a = $('h1').detach();
    $('div').hide();
    $(a).prependTo('body');    
});

(You will need to modify...)

Example #2: http://jsfiddle.net/ZgEMM/4/

Method to convert a List<List> to List :

listOfLists.stream().flatMap(List::stream).collect(Collectors.toList());

See this example:

public class Example {

    public static void main(String[] args) {
        List<List<String>> listOfLists = Collections.singletonList(Arrays.asList("a", "b", "v"));
        List<String> list = listOfLists.stream().flatMap(List::stream).collect(Collectors.toList());

        System.out.println("listOfLists => " + listOfLists);
        System.out.println("list => " + list);
    }

}       

It prints:

listOfLists => [[a, b, c]]
list => [a, b, c]

In Python this can be done using List Comprehension.

list_of_lists = [['Roopa','Roopi','Tabu', 'Soudipta'],[180.0, 1231, 2112, 3112], [130], [158.2], [220.2]]

flatten = [val for sublist in list_of_lists for val in sublist]

print(flatten)

['Roopa', 'Roopi', 'Tabu', 'Soudipta', 180.0, 1231, 2112, 3112, 130, 158.2, 220.2]

If you have an association on a property pointing to the user (let's say Credit\Entity\UserCreditHistory#user, picked from your example), then the syntax is quite simple:

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin('a.user', 'u')
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

Since you are applying a condition on the joined result here, using a LEFT JOIN or simply JOIN is the same.

If no association is available, then the query looks like following

public function getHistory($users) {
    $qb = $this->entityManager->createQueryBuilder();
    $qb
        ->select('a', 'u')
        ->from('Credit\Entity\UserCreditHistory', 'a')
        ->leftJoin(
            'User\Entity\User',
            'u',
            \Doctrine\ORM\Query\Expr\Join::WITH,
            'a.user = u.id'
        )
        ->where('u = :user')
        ->setParameter('user', $users)
        ->orderBy('a.created_at', 'DESC');

    return $qb->getQuery()->getResult();
}

This will produce a resultset that looks like following:

array(
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    array(
        0 => UserCreditHistory instance,
        1 => Userinstance,
    ),
    // ...
)

The browser's native JSON API may not give you back your idOld function after you call JSON.stringify, however, if can stringify your JSON yourself (maybe use Crockford's json2.js instead of browser's API), then if you have a string of JSON e.g.

var person_json = "{ \"age:\" : 20, \"isOld:\": false, isOld: function() { return this.age > 60; } }";

then you can call

eval("(" + person + ")") 

, and you will get back your function in the json object.

Here's the mysql reference for cursors. So I'm guessing it's something like this:

  DECLARE done INT DEFAULT 0;
  DECLARE products_id INT;
  DECLARE result varchar(4000);
  DECLARE cur1 CURSOR FOR SELECT products_id FROM sets_products WHERE set_id = 1;
  DECLARE CONTINUE HANDLER FOR NOT FOUND SET done = 1;

  OPEN cur1;

  REPEAT
    FETCH cur1 INTO products_id;
    IF NOT done THEN
      CALL generate_parameter_list(@product_id, @result);
      SET param = param + "," + result; -- not sure on this syntax
    END IF;
  UNTIL done END REPEAT;

  CLOSE cur1;

  -- now trim off the trailing , if desired

I got the answer.

Here is the code:

SELECT * FROM table
WHERE STR_TO_DATE(column, '%d/%m/%Y')
  BETWEEN STR_TO_DATE('29/01/15', '%d/%m/%Y')
    AND STR_TO_DATE('07/10/15', '%d/%m/%Y')

You need to call .validate() before you can add rules this way, like this:

$("#myForm").validate(); //sets up the validator
$("input[id*=Hours]").rules("add", "required");

The .validate() documentation is a good guide, here's the blurb about .rules("add", option):

Adds the specified rules and returns all rules for the first matched element. Requires that the parent form is validated, that is, $("form").validate() is called first.

In case my I try to set up proxy from android studio Appearance & Behaviour => System Settings => HTTP Proxy. But the proxy did not worked out so I click no proxy.

Checking NO PROXY will not remove the proxy setting from the gradle.properties(Global). You need to manually remove it.

So I remove all the properties starting with systemProp for example - systemProp.http.nonProxyHosts=*.local, localhost

Most of those tools are listed in the PostgreSQL wiki:

parentElement is new to Firefox 9 and to DOM4, but it has been present in all other major browsers for ages.

In most cases, it is the same as parentNode. The only difference comes when a node's parentNode is not an element. If so, parentElement is null.

As an example:

document.body.parentNode; // the <html> element
document.body.parentElement; // the <html> element

document.documentElement.parentNode; // the document node
document.documentElement.parentElement; // null

(document.documentElement.parentNode === document);  // true
(document.documentElement.parentElement === document);  // false

Since the <html> element (document.documentElement) doesn't have a parent that is an element, parentElement is null. (There are other, more unlikely, cases where parentElement could be null, but you'll probably never come across them.)

TL;DR

SELECT json_agg(t) FROM t

for a JSON array of objects, and

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

for a JSON object of arrays.

List of objects

This section describes how to generate a JSON array of objects, with each row being converted to a single object. The result looks like this:

[{"a":1,"b":"value1"},{"a":2,"b":"value2"},{"a":3,"b":"value3"}]

9.3 and up

The json_agg function produces this result out of the box. It automatically figures out how to convert its input into JSON and aggregates it into an array.

SELECT json_agg(t) FROM t

There is no jsonb (introduced in 9.4) version of json_agg. You can either aggregate the rows into an array and then convert them:

SELECT to_jsonb(array_agg(t)) FROM t

or combine json_agg with a cast:

SELECT json_agg(t)::jsonb FROM t

My testing suggests that aggregating them into an array first is a little faster. I suspect that this is because the cast has to parse the entire JSON result.

9.2

9.2 does not have the json_agg or to_json functions, so you need to use the older array_to_json:

SELECT array_to_json(array_agg(t)) FROM t

You can optionally include a row_to_json call in the query:

SELECT array_to_json(array_agg(row_to_json(t))) FROM t

This converts each row to a JSON object, aggregates the JSON objects as an array, and then converts the array to a JSON array.

I wasn't able to discern any significant performance difference between the two.

Object of lists

This section describes how to generate a JSON object, with each key being a column in the table and each value being an array of the values of the column. It's the result that looks like this:

{"a":[1,2,3], "b":["value1","value2","value3"]}

9.5 and up

We can leverage the json_build_object function:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )
FROM t

You can also aggregate the columns, creating a single row, and then convert that into an object:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

Note that aliasing the arrays is absolutely required to ensure that the object has the desired names.

Which one is clearer is a matter of opinion. If using the json_build_object function, I highly recommend putting one key/value pair on a line to improve readability.

You could also use array_agg in place of json_agg, but my testing indicates that json_agg is slightly faster.

There is no jsonb version of the json_build_object function. You can aggregate into a single row and convert:

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Unlike the other queries for this kind of result, array_agg seems to be a little faster when using to_jsonb. I suspect this is due to overhead parsing and validating the JSON result of json_agg.

Or you can use an explicit cast:

SELECT
    json_build_object(
        'a', json_agg(t.a),
        'b', json_agg(t.b)
    )::jsonb
FROM t

The to_jsonb version allows you to avoid the cast and is faster, according to my testing; again, I suspect this is due to overhead of parsing and validating the result.

9.4 and 9.3

The json_build_object function was new to 9.5, so you have to aggregate and convert to an object in previous versions:

SELECT to_json(r)
FROM (
    SELECT
        json_agg(t.a) AS a,
        json_agg(t.b) AS b
    FROM t
) r

or

SELECT to_jsonb(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

depending on whether you want json or jsonb.

(9.3 does not have jsonb.)

9.2

In 9.2, not even to_json exists. You must use row_to_json:

SELECT row_to_json(r)
FROM (
    SELECT
        array_agg(t.a) AS a,
        array_agg(t.b) AS b
    FROM t
) r

Documentation

Find the documentation for the JSON functions in JSON functions.

json_agg is on the aggregate functions page.

Design

If performance is important, ensure you benchmark your queries against your own schema and data, rather than trust my testing.

Whether it's a good design or not really depends on your specific application. In terms of maintainability, I don't see any particular problem. It simplifies your app code and means there's less to maintain in that portion of the app. If PG can give you exactly the result you need out of the box, the only reason I can think of to not use it would be performance considerations. Don't reinvent the wheel and all.

Nulls

Aggregate functions typically give back NULL when they operate over zero rows. If this is a possibility, you might want to use COALESCE to avoid them. A couple of examples:

SELECT COALESCE(json_agg(t), '[]'::json) FROM t

Or

SELECT to_jsonb(COALESCE(array_agg(t), ARRAY[]::t[])) FROM t

Create Table as select (CTAS) is possible in Hive.

You can try out below command:

CREATE TABLE new_test 
    row format delimited 
    fields terminated by '|' 
    STORED AS RCFile 
AS select * from source where col=1

1. Target cannot be partitioned table.
2. Target cannot be external table.
3. It copies the structure as well as the data

Create table like is also possible in Hive.

1. It just copies the source table definition.

Just use BlueM/tree php class for make tree of a self-relation table in mysql.

Tree and Tree\Node are PHP classes for handling data that is structured hierarchically using parent ID references. A typical example is a table in a relational database where each record’s “parent” field references the primary key of another record. Of course, Tree cannot only use data originating from a database, but anything: you supply the data, and Tree uses it, regardless of where the data came from and how it was processed. read more

Here is an example of using BlueM/tree:

<?php 
require '/path/to/vendor/autoload.php'; $db = new PDO(...); // Set up your database connection 
$stm = $db->query('SELECT id, parent, title FROM tablename ORDER BY title'); 
$records = $stm->fetchAll(PDO::FETCH_ASSOC); 
$tree = new BlueM\Tree($records); 
...

ListViewItem.IsSelected = true;

Another way to get current boost version (Linux Ubuntu):

~$ dpkg -s libboost-dev | grep Version
Version: 1.58.0.1ubuntu1

Ref: https://www.osetc.com/en/how-to-install-boost-on-ubuntu-16-04-18-04-linux.html

Try this:

runas.exe /savecred /user:administrator "%sysdrive%\testScripts\testscript1.ps1" 

It saves the password the first time and never asks again. Maybe when you change the administrator password you will be prompted again.

Why didn't anyone mentioned the method LocalDateTime.toEpochSecond():

LocalDateTime localDateTime = ... // whatever e.g. LocalDateTime.now()
long time2epoch = localDateTime.toEpochSecond(ZoneOffset.UTC);

This seems way shorter that many suggested answers above...

since function is first-class citizen, you can write small wrapper (from Alex answers)

def repeat(f, N):
    for _ in itertools.repeat(None, N): f()

then you can pass function as argument.

CURDATE() will give current date while NOW() will give full date time.

Run the queries, and you will find out whats the difference between them.

SELECT NOW();     -- You will get 2010-12-09 17:10:18
SELECT CURDATE(); -- You will get 2010-12-09

On GKE, if the pod is dead, it's best to check for the events. It will show in more detail what the error is about.

In my case, I had :

Failed to pull image "gcr.io/project/imagename@sha256:c8e91af54fc17faa1c49e2a05def5cbabf8f0a67fc558eb6cbca138061a8400a":
 rpc error: code = Unknown desc = error pulling image configuration: unknown blob

It turned out the image was damaged somehow. After repushing it and deploying with the new hash, it worked again.

The code generates a compilation error because your instance type is an Animal:

Animal animal=new Animal();

Downcasting is not allowed in Java for several reasons. See here for details.

Say your table is called t1 and your primary-key is called id
First, create the sequence:

create sequence t1_seq start with 1 increment by 1 nomaxvalue; 

Then create a trigger that increments upon insert:

create trigger t1_trigger
before insert on t1
for each row
   begin
     select t1_seq.nextval into :new.id from dual;
   end;

You have to first clear the table and then add new data using row.add() function. At last step adjust also column size so that table renders correctly.

$('#upload-new-data').on('click', function () {
   datatable.clear().draw();
   datatable.rows.add(NewlyCreatedData); // Add new data
   datatable.columns.adjust().draw(); // Redraw the DataTable
});

Also if you want to find a mapping between old and new datatable API functions bookmark this

The easiest way to find the best fit in R is to code the model as:

lm.1 <- lm(y ~ x + I(x^2) + I(x^3) + I(x^4) + ...)

After using step down AIC regression

lm.s <- step(lm.1)

$('inputFile').parent().parent().children('td > label').hide();

can help you navigate two levels up ( to TD, to TR ) moving two levels back down ( all TD's in that TR and their LABEL tags ), applying the hide() function there.

if you want to stay at the TR level and hide them:

$('inputFile').parent().parent().hide();

… is sufficient.

you can navigate very easily through the elements using the jquery selectors.

parent is documented here: http://api.jquery.com/parent/

hide is documented here: http://api.jquery.com/hide/

    $(window).on('show.bs.dropdown', function (e) {

    // grab the menu        
    dropdownMenu = $(e.target).find('.dropdown-menu');

    // detach it and append it to the body
    $('body').append(dropdownMenu.detach());

    // grab the new offset position
    var eOffset = $(e.target).offset();

    // make sure to place it where it would normally go (this could be improved)

OUTPUT:-

There is also an experimental technology called Broadcast Channel API that is designed specifically for communication between different browser contexts with same origin. You can post messages to and recieve messages from another browser context without having a reference to it:

var channel = new BroadcastChannel("foo");
channel.onmessage = function( e ) {
  // Process messages from other contexts.
};
// Send message to other listening contexts.
channel.postMessage({ value: 42, type: "bar"});

Obviously this is experiental technology and is not supported accross all browsers yet.

There are two options, really:

1. Use standard collections, as explained by Shakedown
2. Use Arrays.sort

E.g.,

int[] ints = {11367, 11358, 11421, 11530, 11491, 11218, 11789};
Arrays.sort(ints);
System.out.println(Arrays.asList(ints));

That of course assumes that you already have your integers as an array. If you need to parse those first, look for String.split and Integer.parseInt.

This is a place in which C++ has a strange rule. Before being able to compile a call to a function the compiler must know the function name, return value and all parameters. This can be done by adding a "prototype". In your case this simply means adding before main the following line:

int writeFile();

this tells the compiler that there exist a function named writeFile that will be defined somewhere, that returns an int and that accepts no parameters.

Alternatively you can define first the function writeFile and then main because in this case when the compiler gets to main already knows your function.

Note that this requirement of knowing in advance the functions being called is not always applied. For example for class members defined inline it's not required...

struct Foo {
    void bar() {
        if (baz() != 99) {
            std::cout << "Hey!";
        }
    }

    int baz() {
        return 42;
    }
};

In this case the compiler has no problem analyzing the definition of bar even if it depends on a function baz that is declared later in the source code.

#include <stdio.h>
#include <string.h>

int main(void){
    char word[17], outword[33];//17:16+1, 33:16*2+1
    int i, len;

    printf("Intro word:");
    fgets(word, sizeof(word), stdin);
    len = strlen(word);
    if(word[len-1]=='\n')
        word[--len] = '\0';

    for(i = 0; i<len; i++){
        sprintf(outword+i*2, "%02X", word[i]);
    }
    printf("%s\n", outword);
    return 0;
}

Add android:layout_centerInParent="true" to element which you want to center in the RelativeLayout

I needed something similar, the ability to click on a set of icons to indicate a choice, or a text-based choice and have that update the model (2-way-binding) with the represented value and to also a way to indicate which was selected visually. I created an AngularJS directive for it, since it needed to be flexible enough to handle any HTML element being clicked on to indicate a choice.

<ul ng-repeat="vote in votes" ...>
    <li data-choice="selected" data-value="vote.id">...</li>
</ul>

Solution: http://jsfiddle.net/brandonmilleraz/5fr9V/

See the javadoc

of List

list.get(0);

or Set

set.iterator().next();

and check the size before using the above methods by invoking isEmpty()

!list_or_set.isEmpty()

Also work for me when I need to move back as in file system. P.S. @angular: "^5.0.0"

Steps to find the UDID from IPhone and IPad Without Using itunes

1. Open below link in your iPhone or iPad : - http://get.udid.io/

2. Click on the Button Green color - Tap to find UDID

3. Get your UDID will Appear, Click on the right side top INSTALL button

4 . UDID will appear Copy the UDID.

We use the logging module for this.

For example:

import logging
class SomeTest( unittest.TestCase ):
    def testSomething( self ):
        log= logging.getLogger( "SomeTest.testSomething" )
        log.debug( "this= %r", self.this )
        log.debug( "that= %r", self.that )
        # etc.
        self.assertEquals( 3.14, pi )

if __name__ == "__main__":
    logging.basicConfig( stream=sys.stderr )
    logging.getLogger( "SomeTest.testSomething" ).setLevel( logging.DEBUG )
    unittest.main()

That allows us to turn on debugging for specific tests which we know are failing and for which we want additional debugging information.

My preferred method, however, isn't to spend a lot of time on debugging, but spend it writing more fine-grained tests to expose the problem.

Easy.

if (empty($_GET)) {
    // $_GET is empty
}

You can just convert the string like that [str intValue] or [str integerValue]

integerValue Returns the NSInteger value of the receiver’s text.

• (NSInteger)integerValue Return Value The NSInteger value of the receiver’s text, assuming a decimal representation and skipping whitespace at the beginning of the string. Returns 0 if the receiver doesn’t begin with a valid decimal text representation of a number.

for more information refer here

You can also add hash when page is loading:

location.hash = "noBack";

Then just handle location hash change to add another hash:

$(window).on('hashchange', function() {
    location.hash = "noBack";
});

That makes hash always present and back button tries to remove hash at first. Hash is then added again by "hashchange" handler - so page would never actually can be changed to previous one.

The easisest thing to do is to wrap your code in a transaction, and then execute each batch of T-SQL code line by line.

For example,

Begin Transaction

         -Do some T-SQL queries here.

Rollback transaction -- OR commit transaction

If you want to incorporate error handling you can do so by using a TRY...CATCH BLOCK. Should an error occur you can then rollback the tranasction within the catch block.

For example:

USE AdventureWorks;
GO
BEGIN TRANSACTION;

BEGIN TRY
    -- Generate a constraint violation error.
    DELETE FROM Production.Product
    WHERE ProductID = 980;
END TRY
BEGIN CATCH
    SELECT 
        ERROR_NUMBER() AS ErrorNumber
        ,ERROR_SEVERITY() AS ErrorSeverity
        ,ERROR_STATE() AS ErrorState
        ,ERROR_PROCEDURE() AS ErrorProcedure
        ,ERROR_LINE() AS ErrorLine
        ,ERROR_MESSAGE() AS ErrorMessage;

    IF @@TRANCOUNT > 0
        ROLLBACK TRANSACTION;
END CATCH;

IF @@TRANCOUNT > 0
    COMMIT TRANSACTION;
GO

Hope this helps but please let me know if you need more details.

You can plot several columns at once by supplying a list of column names to the plot's y argument.

df.plot(x="X", y=["A", "B", "C"], kind="bar")

This will produce a graph where bars are sitting next to each other.

In order to have them overlapping, you would need to call plot several times, and supplying the axes to plot to as an argument ax to the plot.

import pandas as pd
import matplotlib.pyplot as plt
import numpy as np

y = np.random.rand(10,4)
y[:,0]= np.arange(10)
df = pd.DataFrame(y, columns=["X", "A", "B", "C"])

ax = df.plot(x="X", y="A", kind="bar")
df.plot(x="X", y="B", kind="bar", ax=ax, color="C2")
df.plot(x="X", y="C", kind="bar", ax=ax, color="C3")

plt.show()

I don't think you can drop all tables in one hit but you can do the following to get the commands:

select 'drop table ' || name || ';' from sqlite_master
    where type = 'table';

The output of this is a script that will drop the tables for you. For indexes, just replace table with index.

You can use other clauses in the where section to limit which tables or indexes are selected (such as "and name glob 'pax_*'" for those starting with "pax_").

You could combine the creation of this script with the running of it in a simple bash (or cmd.exe) script so there's only one command to run.

If you don't care about any of the information in the DB, I think you can just delete the file it's stored in off the hard disk - that's probably faster. I've never tested this but I can't see why it wouldn't work.

In C, it is a common idiom to zero out the memory for a struct using memset:

struct x myStruct;
memset(&myStruct, 0, sizeof(myStruct));

Technically speaking, I don't believe that this is portable because it assumes that the NULL pointer on a machine is represented by the integer value 0, but it's used widely because on most machines this is the case.

If you move from C to C++, be careful not to use this technique on every object. C++ only makes this legal on objects with no member functions and no inheritance.

You can do :

df['industry'] = 'yyy'

To remove trailing white space while ignoring empty lines I use positive look-behind:

(?<=\S)\s+$

The look-behind is the way go to exclude the non-whitespace (\S) from the match.

For removing the particular object from arrayList there are two ways. Call the function of arrayList.

1. Removing on the basis of the object.

arrayList.remove(object);

This will remove your object but in most cases when arrayList contains the items of UserDefined DataTypes, this method does not give you the correct result. It works fine only for Primitive DataTypes. Because user want to remove the item on the basis of object field value and that can not be compared by remove function automatically.

2. Removing on the basis of specified index position of arrayList. The best way to remove any item or object from arrayList. First, find the index of the item which you want to remove. Then call this arrayList method, this method removes the item on index basis. And it will give the correct result.

arrayList.remove(index);  

Without resorting to an XSLT-based solution, if you want clean, elegant and smart, you'd need some support from the framework, in particular, the visitor pattern could make this a breeze. Unfortunately, it's not available here.

I've implemented it inspired by LINQ's ExpressionVisitor to have a similar structure to it. With this, you can apply the visitor pattern to (LINQ-to-) XML objects. (I've done limited testing on this but it works well as far as I can tell)

And a little helper method to get the ball rolling:

T ChangeNamespace<T>(T node, XNamespace fromNs, XNamespace toNs, string toPrefix = null) where T : XObject
{
    return node.Accept(
        new ChangeNamespaceVisitor(
            new NamespaceMappingManager()
                .Add(fromNs, toNs, toPrefix)
        )
    ) as T;
}

Then to remove a namespace, you could call it like so:

var doc = ChangeNamespace(XDocument.Load(pathToXml),
    fromNs: "http://schema.peters.com/doc_353/1/Types",
    toNs: null);

Using this visitor, you can write a INamespaceMappingManager to remove all namespaces.

T RemoveAllNamespaces<T>(T node) where T : XObject
{
    return node.Accept(
        new ChangeNamespaceVisitor(new RemoveNamespaceMappingManager())
    ) as T;
}

public class RemoveNamespaceMappingManager : INamespaceMappingManager
{
    public INamespaceMapping GetMapping(XNamespace fromNs)
    {
        return new RemoveNamespaceMapping();
    }

    private class RemoveNamespaceMapping : INamespaceMapping
    {
        public XName ChangeNamespace(XName name)
        {
            return name.LocalName;
        }

        public XObject ChangeNamespaceDeclaration(XAttribute node)
        {
            return null;
        }
    }
}

To get the row numbers where at least one item is larger than 15:

Cstr() is compiled inline for better performance.

CType allows for casts between types if a conversion operator is defined

ToString() Between base type and string throws an exception if conversion is not possible.

TryParse() From String to base typeif possible otherwise returns false

DirectCast used if the types are related via inheritance or share a common interface , will throw an exception if the cast is not possible, trycast will return nothing in this instance

To change color of title in controller:

UINavigationBar.appearance().titleTextAttributes = [NSAttributedString.Key.foregroundColor: UIColor.white]

Here is another solution

Set a hidden scope variable in your html then you can use it from your controller:

<span style="display:none" >{{ formValid = myForm.$valid}}</span>

Here is the full working example:

angular.module('App', [])_x000D_
.controller('myController', function($scope) {_x000D_
  $scope.userType = 'guest';_x000D_
  $scope.formValid = false;_x000D_
  console.info('Ctrl init, no form.');_x000D_
  _x000D_
  $scope.$watch('myForm', function() {_x000D_
    console.info('myForm watch');_x000D_
    console.log($scope.formValid);_x000D_
  });_x000D_
  _x000D_
  $scope.isFormValid = function() {_x000D_
    //test the new scope variable_x000D_
    console.log('form valid?: ', $scope.formValid);_x000D_
  };_x000D_
});

<!doctype html>_x000D_

_x000D_
<form name="myForm" ng-controller="myController">_x000D_
  userType: <input name="input" ng-model="userType" required>_x000D_
  <span class="error" ng-show="myForm.input.$error.required">Required!</span><br>_x000D_
  <tt>userType = {{userType}}</tt><br>_x000D_
  <tt>myForm.input.$valid = {{myForm.input.$valid}}</tt><br>_x000D_
  <tt>myForm.input.$error = {{myForm.input.$error}}</tt><br>_x000D_
  <tt>myForm.$valid = {{myForm.$valid}}</tt><br>_x000D_
  <tt>myForm.$error.required = {{!!myForm.$error.required}}</tt><br>_x000D_
  _x000D_
  _x000D_
  /*-- Hidden Variable formValid to use in your controller --*/_x000D_
  <span style="display:none" >{{ formValid = myForm.$valid}}</span>_x000D_
  _x000D_

Apparently, not only the absolute speeds but also the speed order (as reported by user1579844) are machine dependent; here's what I found:

a=np.empty(1e4); a.fill(5) is fastest;

In descending speed order:

timeit a=np.empty(1e4); a.fill(5) 
# 100000 loops, best of 3: 10.2 us per loop
timeit a=np.empty(1e4); a[:]=5
# 100000 loops, best of 3: 16.9 us per loop
timeit a=np.ones(1e4)*5
# 100000 loops, best of 3: 32.2 us per loop
timeit a=np.tile(5,[1e4])
# 10000 loops, best of 3: 90.9 us per loop
timeit a=np.repeat(5,(1e4))
# 10000 loops, best of 3: 98.3 us per loop
timeit a=np.array([5]*int(1e4))
# 1000 loops, best of 3: 1.69 ms per loop (slowest BY FAR!)

So, try and find out, and use what's fastest on your platform.

You can make use of Google Guava utilities, as shown below

 list = ImmutableSet.copyOf(list).asList(); 

This is probably the most efficient way of eliminating the duplicates from the list and interestingly, it preserves the iteration order as well.

UPDATE

But, in case, you don't want to involve Guava then duplicates can be removed as shown below.

ArrayList<String> list = new ArrayList<String>();
    list.add("Krishna");
    list.add("Krishna");
    list.add("Kishan");
    list.add("Krishn");
    list.add("Aryan");
    list.add("Harm");

System.out.println("List"+list);
HashSet hs = new HashSet();
hs.addAll(list);
list.clear();
list.addAll(hs);

But, of course, this will destroys the iteration order of the elements in the ArrayList.

You probably only forgot to create database. Enter your PHPMyAdmin and do it from there.

Edit: Definitely don't go with Maulik's answer. Not only it is using mysql_ extenstion (which is commonly recognized bad practice), Laravel is also taking care of your connections using PDO.

You can't create arrays with a generic component type.

Create an array of an explicit type, like Object[], instead. You can then cast this to PCB[] if you want, but I don't recommend it in most cases.

PCB[] res = (PCB[]) new Object[list.size()]; /* Not type-safe. */

If you want type safety, use a collection like java.util.List<PCB> instead of an array.

By the way, if list is already a java.util.List, you should use one of its toArray() methods, instead of duplicating them in your code. This doesn't get your around the type-safety problem though.

As you've tagged this jQuery ...

First, put IDs on your input buttons and remove the inline handlers:

<input type="number" id="input" />
<input type="button" id="stop" value="stop"/>
<input type="button" id="start" value="start"/>

Then keep all of your state and functions encapsulated in a closure:

EDIT updated for a cleaner implementation, that also addresses @Esailija's concerns about use of setInterval().

$(function() {
    var timer = null;
    var input = document.getElementById('input');

    function tick() {
        ++input.value;
        start();        // restart the timer
    };

    function start() {  // use a one-off timer
        timer = setTimeout(tick, 1000);
    };

    function stop() {
        clearTimeout(timer);
    };

    $('#start').bind("click", start); // use .on in jQuery 1.7+
    $('#stop').bind("click", stop);

    start();  // if you want it to auto-start
});

This ensures that none of your variables leak into global scope, and can't be modified from outside.

There isn't a "pure python" way to do this because some other process would have to launch python in order to run your solution. Every platform will have one or twenty different ways to launch processes and monitor their progress. On unix platforms, cron is the old standard. On Mac OS X there is also launchd, which combines cron-like launching with watchdog functionality that can keep your process alive if that's what you want. Once python is running, then you can use the sched module to schedule tasks.

To update this, in Swift it can be done easily with:

array.reverse()

You can do this :

    df <- data.frame("a" = c(1,2,3,4), "b" = c(4,3,2,1), "x_ind" = c(1,0,1,1), "y_ind" = c(0,0,1,1), "z_ind" = c(0,1,1,1) )
df %>% mutate( bi  = ifelse((df$x_ind + df$y_ind +df$z_ind)== 3, 1,0 ))

First write properly. You want to navigate within an application for another link from your application for another link. Here is the code:

window.location.href = "http://www.google.com";

And if you want to navigate pages within your application then I also have code, if you want.

I have read or heard that Mac OS X is written mostly in Objective-C with some of the lower level parts, such as the kernel, and hardware device drivers written in C. I believe that Apple "eat(s) its own dog food", meaning that they write Mac OS X using their own Xcode Developer Tools. The GCC(GNU Compiler Collection) compiler-linker is the unix command line tool that xCode used for most of its compiling and/or linking of executables. Among other possible languages, I know GCC compiles source code from the C, Objective-C, C++ and Objective-C++ languages.

On Mac OS X Lion with the latest macport:

sudo port install curl-ca-bundle  
export SSL_CERT_FILE=/opt/local/share/curl/curl-ca-bundle.crt  

Then, rerun the failed job.

Note, the cert file location seems to have changed since Eric G answered on May 12.

You have to add the selector parameter, otherwise the event is directly bound instead of delegated, which only works if the element already exists (so it doesn't work for dynamically loaded content).

See http://api.jquery.com/on/#direct-and-delegated-events

Change your code to

$(document.body).on('click', '.update' ,function(){

The jQuery set receives the event then delegates it to elements matching the selector given as argument. This means that contrary to when using live, the jQuery set elements must exist when you execute the code.

As this answers receives a lot of attention, here are two supplementary advises :

1) When it's possible, try to bind the event listener to the most precise element, to avoid useless event handling.

That is, if you're adding an element of class b to an existing element of id a, then don't use

$(document.body).on('click', '#a .b', function(){

but use

$('#a').on('click', '.b', function(){

2) Be careful, when you add an element with an id, to ensure you're not adding it twice. Not only is it "illegal" in HTML to have two elements with the same id but it breaks a lot of things. For example a selector "#c" would retrieve only one element with this id.

Since nobody has mentioned it, I'd like to add that Facebook chat is written in Erlang.

The ioctl function is useful for implementing a device driver to set the configuration on the device. e.g. a printer that has configuration options to check and set the font family, font size etc. ioctl could be used to get the current font as well as set the font to a new one. A user application uses ioctl to send a code to a printer telling it to return the current font or to set the font to a new one.

int ioctl(int fd, int request, ...)

1. fd is file descriptor, the one returned by open;
2. request is request code. e.g GETFONT will get the current font from the printer, SETFONT will set the font on the printer;
3. the third argument is void *. Depending on the second argument, the third may or may not be present, e.g. if the second argument is SETFONT, the third argument can be the font name such as "Arial";

int request is not just a macro. A user application is required to generate a request code and the device driver module to determine which configuration on device must be played with. The application sends the request code using ioctl and then uses the request code in the device driver module to determine which action to perform.

A request code has 4 main parts

    1. A Magic number - 8 bits
    2. A sequence number - 8 bits
    3. Argument type (typically 14 bits), if any.
    4. Direction of data transfer (2 bits).  

If the request code is SETFONT to set font on a printer, the direction for data transfer will be from user application to device driver module (The user application sends the font name "Arial" to the printer). If the request code is GETFONT, direction is from printer to the user application.

In order to generate a request code, Linux provides some predefined function-like macros.

1._IO(MAGIC, SEQ_NO) both are 8 bits, 0 to 255, e.g. let us say we want to pause printer. This does not require a data transfer. So we would generate the request code as below

#define PRIN_MAGIC 'P'
#define NUM 0
#define PAUSE_PRIN __IO(PRIN_MAGIC, NUM) 

and now use ioctl as

ret_val = ioctl(fd, PAUSE_PRIN);

The corresponding system call in the driver module will receive the code and pause the printer.

2. __IOW(MAGIC, SEQ_NO, TYPE) MAGIC and SEQ_NO are the same as above, and TYPE gives the type of the next argument, recall the third argument of ioctl is void *. W in __IOW indicates that the data flow is from user application to driver module. As an example, suppose we want to set the printer font to "Arial".

#define PRIN_MAGIC 'S'
#define SEQ_NO 1
#define SETFONT __IOW(PRIN_MAGIC, SEQ_NO, unsigned long)

further,

char *font = "Arial";
ret_val = ioctl(fd, SETFONT, font); 

Now font is a pointer, which means it is an address best represented as unsigned long, hence the third part of _IOW mentions type as such. Also, this address of font is passed to corresponding system call implemented in device driver module as unsigned long and we need to cast it to proper type before using it. Kernel space can access user space and hence this works. other two function-like macros are __IOR(MAGIC, SEQ_NO, TYPE) and __IORW(MAGIC, SEQ_NO, TYPE) where the data flow will be from kernel space to user space and both ways respectively.

Please let me know if this helps!

You can find something about this in the Adobe Developer FAQ. (It's a PDF document rather than a web page, which I guess is unsurprising in this particular case.)

The FAQ notes that the use of the command line switches is unsupported.

To open a file it's:

AcroRd32.exe <filename>

The following switches are available:

• /n - Launch a new instance of Reader even if one is already open
• /s - Don't show the splash screen
• /o - Don't show the open file dialog
• /h - Open as a minimized window
• /p <filename> - Open and go straight to the print dialog
• /t <filename> <printername> <drivername> <portname> - Print the file the specified printer.

That response is a string too, if you want to send the response prettified, for some awkward reason, you could use something like JSON.stringify(anObject, null, 3)

It's important that you set the Content-Type header to application/json, too.

var http = require('http');

var app = http.createServer(function(req,res){
    res.setHeader('Content-Type', 'application/json');
    res.end(JSON.stringify({ a: 1 }));
});
app.listen(3000);

// > {"a":1}

Prettified:

var http = require('http');

var app = http.createServer(function(req,res){
    res.setHeader('Content-Type', 'application/json');
    res.end(JSON.stringify({ a: 1 }, null, 3));
});
app.listen(3000);

// >  {
// >     "a": 1
// >  }

I'm not exactly sure why you want to terminate it with a newline, but you could just do JSON.stringify(...) + '\n' to achieve that.

Express

In express you can do this by changing the options instead.

'json replacer' JSON replacer callback, null by default

'json spaces' JSON response spaces for formatting, defaults to 2 in development, 0 in production

Not actually recommended to set to 40

app.set('json spaces', 40);

Then you could just respond with some json.

res.json({ a: 1 });

It'll use the 'json spaces' configuration to prettify it.

The subquery is being run for each row because it is a correlated query. One can make a correlated query into a non-correlated query by selecting everything from the subquery, like so:

SELECT * FROM
(
    SELECT relevant_field
    FROM some_table
    GROUP BY relevant_field
    HAVING COUNT(*) > 1
) AS subquery

The final query would look like this:

SELECT *
FROM some_table
WHERE relevant_field IN
(
    SELECT * FROM
    (
        SELECT relevant_field
        FROM some_table
        GROUP BY relevant_field
        HAVING COUNT(*) > 1
    ) AS subquery
)

By using ToDictionary:

var dictionary = list.ToDictionary(s => s);

If it is possible that any string could be repeated, either do a Distinct call first on the list (to remove duplicates), or use ToLookup which allows for multiple values per key.

shared folders VS synced folders

Basically shared folders are renamed to synced folder from v1 to v2 (docs), under the bonnet it is still using vboxsf between host and guest (there is known performance issues if there are large numbers of files/directories).

Vagrantfile directory mounted as /vagrant in guest

Vagrant is mounting the current working directory (where Vagrantfile resides) as /vagrant in the guest, this is the default behaviour.

See docs

NOTE: By default, Vagrant will share your project directory (the directory with the Vagrantfile) to /vagrant.

You can disable this behaviour by adding cfg.vm.synced_folder ".", "/vagrant", disabled: true in your Vagrantfile.

Why synced folder is not working

Based on the output /tmp on host was NOT mounted during up time.

Use VAGRANT_INFO=debug vagrant up or VAGRANT_INFO=debug vagrant reload to start the VM for more output regarding why the synced folder is not mounted. Could be a permission issue (mode bits of /tmp on host should be drwxrwxrwt).

I did a test quick test using the following and it worked (I used opscode bento raring vagrant base box)

config.vm.synced_folder "/tmp", "/tmp/src"

output

$ vagrant reload

Turns out all I needed to do was wrap the left-hand side of the expression in soft brackets:

expand is a unix utility to convert tabs to spaces. If you do not want to set anything in vim, you can use a shell command from vim:

:!% expand -t8

I'm using this solution:

@interface Model
+ (int) value;
+ (void) setValue:(int)val;
@end

@implementation Model
static int value;
+ (int) value
{ @synchronized(self) { return value; } }
+ (void) setValue:(int)val
{ @synchronized(self) { value = val; } }
@end

And i found it extremely useful as a replacement of Singleton pattern.

To use it, simply access your data with dot notation:

Model.value = 1;
NSLog(@"%d = value", Model.value);

//MARK: does not seem to work for me in Xcode 6.3.2. However, this is what I did to get it to work:

1) Code:

import Cocoa

class MainWindowController: NSWindowController {

    //MARK: - My cool methods

    func fly() {
    }

    func turnInvisible() {

    }
}

2) In the jump bar nothing appears to change when adding the //MARK: comment. However, if I click on the rightmost name in the jump bar, in my case it says MainWindowController(with a leading C icon), then a popup window will display showing the effects of the //MARK: comment, namely a heading that says "My cool methods":

3) I also notice that if I click on one of the methods in my code, then the method becomes the rightmost entry in the jump bar. In order to get MainWindowController(with a leading C icon) to be the rightmost entry in the jump bar, I have to click on the whitespace above my methods.

As jcdoming suggested, use Seaborn heatmap():

import seaborn as sns
import matplotlib.pyplot as plt

fig = plt.figure(facecolor='w', edgecolor='k')
sns.heatmap(df.head(), annot=True, cmap='viridis', cbar=False)
plt.savefig('DataFrame.png')

By specifying the @JoinColumn on both models you don't have a two way relationship. You have two one way relationships, and a very confusing mapping of it at that. You're telling both models that they "own" the IDAIRLINE column. Really only one of them actually should! The 'normal' thing is to take the @JoinColumn off of the @OneToMany side entirely, and instead add mappedBy to the @OneToMany.

@OneToMany(cascade = CascadeType.ALL, mappedBy="airline")
public Set<AirlineFlight> getAirlineFlights() {
    return airlineFlights;
}

That tells Hibernate "Go look over on the bean property named 'airline' on the thing I have a collection of to find the configuration."

select replace ( colname, '''', '') AS colname FROM .[dbo].[Db Name]

Try -

Call CatSubProduktAreakum(Stattyp, Daty + UBound(SubCategories) + 2)

As for the reason, this from MSDN via this question - What does the Call keyword do in VB6?

You are not required to use the Call keyword when calling a procedure. However, if you use the Call keyword to call a procedure that requires arguments, argumentlist must be enclosed in parentheses. If you omit the Call keyword, you also must omit the parentheses around argumentlist. If you use either Call syntax to call any intrinsic or user-defined function, the function's return value is discarded.

As it is written in the using-maven docs from the Kotlin website:

You just have to put <kotlin.compiler.jvmTarget>1.8</kotlin.compiler.jvmTarget> into the properties section of your pom.xml

The 'X' only works if partial seconds are not present: i.e. SimpleDateFormat pattern of

"yyyy-MM-dd'T'HH:mm:ssX"

Will correctly parse

"2008-01-31T00:00:00Z"

but

"yyyy-MM-dd'T'HH:mm:ss.SX"

Will NOT parse

"2008-01-31T00:00:00.000Z"

Sad but true, a date-time with partial seconds does not appear to be a valid ISO date: http://en.wikipedia.org/wiki/ISO_8601

1. Go to .gitignore file and add the entry for the files you want to ignore
2. Run git rm -r --cached .
3. Now run git add .

mail -s "Your Subject" [email protected] < /file/with/mail/content

(/file/with/mail/content should be a plaintext file, not a file attachment or an image, etc)

What also works and is even nicer for long, multiline texts, is putting your text indented on the next line, after a pipe or greater-than sign:

text: >
    Op dit plein stond het hoofdkantoor van de NIROM: Nederlands Indische 
    Radio Omroep

A pipe preserves newlines, a gt-sign turns all the following lines into one long string.

Representing complex HTML documents will be difficult and full of corner cases, but I just wanted to share a couple techniques to show how to get this kind of program started. This answer differs in that it uses data abstraction and the toJSON method to recursively build the result

Below, html2json is a tiny function which takes an HTML node as input and it returns a JSON string as the result. Pay particular attention to how the code is quite flat but it's still plenty capable of building a deeply nested tree structure – all possible with virtually zero complexity

<main>_x000D_

In the previous example, the textContent gets a little butchered. To remedy this, we introduce another data constructor, TextElem. We'll have to map over the childNodes (instead of children) and choose to return the correct data type based on e.nodeType – this gets us a littler closer to what we might need

// data Elem = Elem Node | TextElem Node_x000D_
_x000D_
const TextElem = e => ({_x000D_
  toJSON: () => ({_x000D_
    type:_x000D_
      'TextElem',_x000D_
    textContent:_x000D_

const Elem = e => ({_x000D_

    default: return Elem(e)_x000D_
  }_x000D_
}_x000D_
_x000D_
// html2json :: Node -> JSONString_x000D_

Anyway, that's just two iterations on the problem. Of course you'll have to address corner cases where they come up, but what's nice about this approach is that it gives you a lot of flexibility to encode the HTML however you wish in JSON – and without introducing too much complexity

In my experience, you could keep iterating with this technique and achieve really good results. If this answer is interesting to anyone and would like me to expand upon anything, let me know ^_^

If you've to support IE7, a more compatible solution is:

/* only the cells with no cell before (aka the first one) */
td {
    padding-left: 20px;
}
/* only the cells with at least one cell before (aka all except the first one) */
td + td {
    padding-left: 0;
}

Also works fine with li; general sibling selector ~ may be more suitable with mixed elements like a heading h1 followed by paragraphs AND a subheading and then again other paragraphs.

You could also use the the basic structure for the PL/pgSQL CASE with anonymous code block procedure block:

DO $$ BEGIN
    CASE
        WHEN boolean-expression THEN
          statements;
        WHEN boolean-expression THEN
          statements;
        ...
        ELSE
          statements;
    END CASE;
END $$;

Just found this simple method to make HttpResponse content as a json

import json

request = RequestFactory() # ignore this, this just like your request object

response = MyView.as_view()(request) # got response as HttpResponse object

response.render() # call this so we could call response.content after

json_response = json.loads(response.content.decode('utf-8'))

print(json_response) # {"your_json_key": "your json value"}

Hope that helps you

You can use get_cfg_var('cfg_file_path') for that:

To check whether the system is using a configuration file, try retrieving the value of the cfg_file_path configuration setting. If this is available, a configuration file is being used.

var_dump( get_cfg_var('cfg_file_path') );

And you can simply set the location of the php.ini. You're using the command line version, so using the -c parameter you can specifiy the location, e.g.

php -c /home/me/php.ini -f /home/me/test.php

Note that if you use rocket_r it will reverse the colors and somehow it looks more natural and better such as below:

SQL NULL's special, and you have to do WHERE field IS NULL, as NULL cannot be equal to anything,

including itself (ie: NULL = NULL is always false).

See Rule 3 https://en.wikipedia.org/wiki/Codd%27s_12_rules

In my case I was doing show / hide elements of a form according to whether an input element was empty or not, so that when hiding the elements the element following the hidden ones was repositioned occupying its space it was necessary to do a float: left of the element of such an element. Even using a plugin as dependsOn it was necessary to use float.

The command

x/i $pc

can be set to run all the time using the usual configuration mechanism.

The sort method and sorted function allow you to provide a custom function to extract the key used for comparison:

>>> ls = ['Q1.3', 'Q6.1', 'Q1.2']
>>> sorted(ls, key=lambda x: float(x[1:]))
['Q1.2', 'Q1.3', 'Q6.1']

Its possible to do silent install on Android 6 and above. Using the function supplied in the answer by Boris Treukhov, ignore everything else in the post, root is not required either.

Install your app as device admin, you can have full kiosk mode with silent install of updates in the background.

Simple Explanation:

bind() create a new function, a new reference at a function it returns to you.

In parameter after this keyword, you pass in the parameter you want to preconfigure. Actually it does not execute immediately, just prepares for execution.

You can preconfigure as many parameters as you want.

Simple Example to understand bind:

function calculate(operation) {
  if (operation === 'ADD') {
   alert('The Operation is Addition');
  } else if (operation === 'SUBTRACT') {
   alert('The Operation is Subtraction');
  }
}

addBtn.addEventListener('click', calculate.bind(this, 'ADD'));
subtractBtn.addEventListener('click', calculate.bind(this, 'SUBTRACT'));

One situation that is a little different is when developing a CodeIgniter application. CodeIgniter seems to use the shorttags whenever PHP is being used in a template/view, otherwise with models and controllers it always uses the long tags. It's not a hard and fast rule in the framework, but for the most part the framework and a lot of the source from other uses follows this convention.

My two cents? If you never plan on running the code somewhere else, then use them if you want. I'd rather not have to do a massive search and replace when I realize it was a dumb idea.

Bash is the standard for Linux.
My experience is that it is easier to find help for bash than for ksh or csh.

Format the date within the query.

var _myModel = from _m in model.ModelSearch(word)
    select new { date = ((DateTime)_m.Date).ToShortDateString() };

The only problem with this solution is that you won't get any results if ANY of the date values are null. To get around this you could either put conditional statements in your query BEFORE you select the date that ignores date nulls or you could set up a query to get all the results and then loop through all of that info using a foreach loop and assign a value to all dates that are null BEFORE you do your SELECT new.

Example of both:

var _test = from _t in adc.ItemSearchTest(word)
                        where _t.Date != null
                        select new { date = ((DateTime)_t.Date).ToShortDateString() };

The second option requires another query entirely so you can assign values to all nulls. This and the foreach loop would have to be BEFORE your query that selects the values.

var _testA = from _t in adc.ItemSearchTest(word)
                         select _i;

            foreach (var detail in _testA)
            {
                if (detail.Date== null)
                {
                    detail.Date= Convert.ToDateTime("1/1/0001");
                }
            }

Just an idea which I found easier than all of the javascript examples.

In .Net 1.1 and earlier, Application.Exit was not a wise choice and the MSDN docs specifically recommended against it because all message processing stopped immediately.

In later versions however, calling Application.Exit will result in Form.Close being called on all open forms in the application, thus giving you a chance to clean up after yourself, or even cancel the operation all together.

Get first the fragment view and then get from this view your ImageView.

public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    View view = inflater.inflate(R.layout.testclassfragment, container, false);
    ImageView imageView = (ImageView) view.findViewById(R.id.my_image);
    return view;
}

.git/HEAD contains the path of the current ref, the working directory is using as HEAD.

Note that if you have a sorted array, you don't need to check against every other item in the array, just the last item. This should be much faster than checking against all items.

// sortedSourceArray is the source array, already sorted
NSMutableArray *newArray = [[NSMutableArray alloc] initWithObjects:[sortedSourceArray objectAtIndex:0]];
for (int i = 1; i < [sortedSourceArray count]; i++)
{
    if (![[sortedSourceArray objectAtIndex:i] isEqualToString:[sortedSourceArray objectAtIndex:(i-1)]])
    {
        [newArray addObject:[tempArray objectAtIndex:i]];
    }
}

It looks like the NSOrderedSet answers that are also suggested require a lot less code, but if you can't use an NSOrderedSet for some reason, and you have a sorted array, I believe my solution would be the fastest. I'm not sure how it compares with the speed of the NSOrderedSet solutions. Also note that my code is checking with isEqualToString:, so the same series of letters will not appear more than once in newArray. I'm not sure if the NSOrderedSet solutions will remove duplicates based on value or based on memory location.

My example assumes sortedSourceArray contains just NSStrings, just NSMutableStrings, or a mix of the two. If sortedSourceArray instead contains just NSNumbers or just NSDates, you can replace

if (![[sortedSourceArray objectAtIndex:i] isEqualToString:[sortedSourceArray objectAtIndex:(i-1)]])

with

if ([[sortedSourceArray objectAtIndex:i] compare:[sortedSourceArray objectAtIndex:(i-1)]] != NSOrderedSame)

and it should work perfectly. If sortedSourceArray contains a mix of NSStrings, NSNumbers, and/or NSDates, it will probably crash.

This is a quick crafty way of doing it, and also a way to pick a custom size.

I go here:

http://vimeo.com/api/v2/video/[VIDEO ID].php

Download the file, open it, and find the 640 pixels wide thumbnail, it will have a format like so:

https://i.vimeocdn.com/video/[LONG NUMBER HERE]_640.jpg

You take the link, change the 640 for - for example - 1400, and you end up with something like this:

https://i.vimeocdn.com/video/[LONG NUMBER HERE]_1400.jpg

Paste it on your browser search bar and enjoy.

This happens when you move your main class location manually because Netbeans doesn't refresh one of its property files. Open nbproject/project.properties and change the value of main.class to the correct package location.

Create a sub-class User with an id field and screen_name field, like this:

public class User
{
    public string id { get; set; }
    public string screen_name { get; set; }
}

public class Response {

    public string id { get; set; }
    public string text { get; set; }
    public string url { get; set; }
    public string width { get; set; }
    public string height { get; set; }
    public string size { get; set; }
    public string type { get; set; }
    public string timestamp { get; set; }
    public User user { get; set; }
}

Given the following tables..

Domain Table
dom_id | dom_url

Review Table
rev_id | rev_dom_from | rev_dom_for

Try this sql... (It's pretty much the same thing that Stephen Wrighton wrote above) The trick is that you are basically selecting from the domain table twice in the same query and joining the results.

Select d1.dom_url, d2.dom_id from
review r, domain d1, domain d2
where d1.dom_id = r.rev_dom_from
and d2.dom_id = r.rev_dom_for

If you are still stuck, please be more specific with exactly it is that you don't understand.

Take a look at incredible Bluetooth Serial class that has onResume() ability that helped me so much. I hope this helps ;)

This method may be equivalent to Kyle's.

Say your list is of size n and you want k elements.

Random rand = new Random();
for(int i = 0; k>0; ++i) 
{
    int r = rand.Next(0, n-i);
    if(r<k) 
    {
        //include element i
        k--;
    }
} 

Works like a charm :)

Missing the main property?

As previous people have answered npm --save ../location-of-your-packages-root-directory. The ../location-of-your-packages-root-directory however must have two things in order for it to work.

1) package.json in that directory pointed towards

2) main property in the package.json must be set and working i.g. "main": "src/index.js", if the entry file for ../location-of-your-packages-root-directory is ../location-of-your-packages-root-directory/src/index.js

Little addition. You can use boost::function, to create functors from functions and methods, like this:

class Foo
{
public:
    void operator () (int i) { printf("Foo %d", i); }
};
void Bar(int i) { printf("Bar %d", i); }
Foo foo;
boost::function<void (int)> f(foo);//wrap functor
f(1);//prints "Foo 1"
boost::function<void (int)> b(&Bar);//wrap normal function
b(1);//prints "Bar 1"

and you can use boost::bind to add state to this functor

boost::function<void ()> f1 = boost::bind(foo, 2);
f1();//no more argument, function argument stored in f1
//and this print "Foo 2" (:
//and normal function
boost::function<void ()> b1 = boost::bind(&Bar, 2);
b1();// print "Bar 2"

and most useful, with boost::bind and boost::function you can create functor from class method, actually this is a delegate:

class SomeClass
{
    std::string state_;
public:
    SomeClass(const char* s) : state_(s) {}

    void method( std::string param )
    {
        std::cout << state_ << param << std::endl;
    }
};
SomeClass *inst = new SomeClass("Hi, i am ");
boost::function< void (std::string) > callback;
callback = boost::bind(&SomeClass::method, inst, _1);//create delegate
//_1 is a placeholder it holds plase for parameter
callback("useless");//prints "Hi, i am useless"

You can create list or vector of functors

std::list< boost::function<void (EventArg e)> > events;
//add some events
....
//call them
std::for_each(
        events.begin(), events.end(), 
        boost::bind( boost::apply<void>(), _1, e));

There is one problem with all this stuff, compiler error messages is not human readable :)

Arrays are, in general, a poor data structure to use if you want to ask if a particular object is in the collection or not.

If you'll be running this search frequently, it might be worth it to use a Dictionary<string, something> rather than an array. Lookups in a Dictionary are O(1) (constant-time), while searching through the array is O(N) (takes time proportional to the length of the array).

Even if the array is only 200 items at most, if you do a lot of these searches, the Dictionary will likely be faster.

In my search for a creating a v4 uuid, I came first to this page, then found this on http://php.net/manual/en/function.com-create-guid.php

function guidv4()
{
    if (function_exists('com_create_guid') === true)
        return trim(com_create_guid(), '{}');

    $data = openssl_random_pseudo_bytes(16);
    $data[6] = chr(ord($data[6]) & 0x0f | 0x40); // set version to 0100
    $data[8] = chr(ord($data[8]) & 0x3f | 0x80); // set bits 6-7 to 10
    return vsprintf('%s%s-%s-%s-%s-%s%s%s', str_split(bin2hex($data), 4));
}

credit: pavel.volyntsev

Edit: to clarify, this function will always give you a v4 uuid (PHP >= 5.3.0).

When the com_create_guid function is available (usually only on Windows), it will use that and strip the curly braces.

If not present (Linux), it will fall back on this strong random openssl_random_pseudo_bytes function, it will then uses vsprintf to format it into v4 uuid.

function CSVParse(csvFile)
{
    this.rows = [];

    var fieldRegEx = new RegExp('(?:\s*"((?:""|[^"])*)"\s*|\s*((?:""|[^",\r\n])*(?:""|[^"\s,\r\n]))?\s*)(,|[\r\n]+|$)', "g");   
    var row = [];
    var currMatch = null;

    while (currMatch = fieldRegEx.exec(this.csvFile))
    {
        row.push([currMatch[1], currMatch[2]].join('')); // concatenate with potential nulls

        if (currMatch[3] != ',')
        {
            this.rows.push(row);
            row = [];
        }

        if (currMatch[3].length == 0)
            break;
    }
}

I like to have the regex do as much as possible. This regex treats all items as either quoted or unquoted, followed by either a column delimiter, or a row delimiter. Or the end of text.

Which is why that last condition -- without it it would be an infinite loop since the pattern can match a zero length field (totally valid in csv). But since $ is a zero length assertion, it won't progress to a non match and end the loop.

And FYI, I had to make the second alternative exclude quotes surrounding the value; seems like it was executing before the first alternative on my javascript engine and considering the quotes as part of the unquoted value. I won't ask -- just got it to work.

pip wheel is another option you should consider:

pip wheel mypackage -w .\outputdir

It will download packages and their dependencies to a directory (current working directory by default), but it performs the additional step of converting any source packages to wheels.

It conveniently supports requirements files:

pip wheel -r requirements.txt -w .\outputdir

Add the --no-deps argument if you only want the specifically requested packages:

pip wheel mypackage -w .\outputdir --no-deps

Why does this happen?

It seems this section on w3.org suggests that text-overflow applies only to block elements:

11.1.  Overflow Ellipsis: the ‘text-overflow’ property

text-overflow      clip | ellipsis | <string>  
Initial:           clip   
APPLIES TO:        BLOCK CONTAINERS               <<<<
Inherited:         no  
Percentages:       N/A  
Media:             visual  
Computed value:    as specified  

The MDN says the same.

This jsfiddle has your code (with a few debug modifications), which works fine if it's applied to a div instead of a td. It also has the only workaround I could quickly think of, by wrapping the contents of the td in a containing div block. However, that looks like "ugly" markup to me, so I'm hoping someone else has a better solution. The code to test this looks like this:

td, div {_x000D_
  overflow: hidden;_x000D_
  text-overflow: ellipsis;_x000D_
  white-space: nowrap;_x000D_
  border: 1px solid red;_x000D_
  width: 80px;_x000D_
}

Works, but no tables anymore:_x000D_
<div>Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah.</div>_x000D_
_x000D_
Works, but non-semantic markup required:_x000D_
<table><tr><td><div>Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah. Lorem ipsum and dim sum yeah yeah yeah.</div></td></tr></table>

rng.step(n=1) {| obj | block } => rng

Iterates over rng, passing each nth element to the block. If the range contains numbers or strings, natural ordering is used. Otherwise step invokes succ to iterate through range elements. The following code uses class Xs, which is defined in the class-level documentation.

range = Xs.new(1)..Xs.new(10)
range.step(2) {|x| puts x}
range.step(3) {|x| puts x}

produces:

1 x
3 xxx
5 xxxxx
7 xxxxxxx
9 xxxxxxxxx
1 x
4 xxxx

The direct answer is that you can't. You must select either an aggregate or something that you are grouping by.

So, you need an alternative approach.

1). Take you current query and join the base data back on it

SELECT
  cpe.*
FROM
  Filteredfmgcms_claimpaymentestimate cpe
INNER JOIN
  (yourQuery) AS lookup
    ON  lookup.MaxData           = cpe.createdOn
    AND lookup.fmgcms_cpeclaimid = cpe.fmgcms_cpeclaimid

2). Use a CTE to do it all in one go...

WITH
  sequenced_data AS
(
  SELECT
    *,
    ROW_NUMBER() OVER (PARITION BY fmgcms_cpeclaimid ORDER BY CreatedOn DESC) AS sequence_id
  FROM
    Filteredfmgcms_claimpaymentestimate
  WHERE
    createdon < 'reportstartdate'
)
SELECT
  *
FROM
  sequenced_data
WHERE
  sequence_id = 1

NOTE: Using ROW_NUMBER() will ensure just one record per fmgcms_cpeclaimid. Even if multiple records are tied with the exact same createdon value. If you can have ties, and want all records with the same createdon value, use RANK() instead.

The "generic" way of doing this is to parse the string from the start, throwing away all the characters before the first bracket, recording the characters after the first bracket, and throwing away the characters after the second bracket.

I'm sure there's a regex library or something to do it though.

This will probably only affect a small percentage of people, but in my case my project was using CocoaPods and one of those pods had a sub spec with its own CocoaPods. The solution was to use full angle imports to reference any files in the sub-pods.

#import <HexColors/HexColor.h>

Rather than

#import "HexColor.h"

If you mean that you want to enable the submit after the user has typed at least one character, then you need to attach a key event that will check it for you.

Something like:

$("#fbss").keypress(function() {
    if($(this).val().length > 1) {
         // Enable submit button
    } else {
         // Disable submit button
    }
});

I'm adding my comment as an answer because it solves the original problem for a wider range of cases than the accepted answer. Note: you must still know the maximum length and the approximate proportion of multi-byte characters that your data will have.

If you have a CLOB greater than 4000 bytes, you need to use DBMS_LOB.SUBSTR rather than SUBSTR. Note that the amount and offset parameters are reversed in DBMS_LOB.SUBSTR.

Next, you may need to substring an amount less than 4000, because this parameter is the number of characters, and if you have multi-byte characters then 4000 characters will be more than 4000 bytes long, and you'll get ORA-06502: PL/SQL: numeric or value error: character string buffer too small because the substring result needs to fit in a VARCHAR2 which has a 4000 byte limit. Exactly how many characters you can retrieve depends on the average number of bytes per character in your data.

So my answer is:

LENGTHB(TO_CHAR(DBMS_LOB.SUBSTR(<CLOB-Column>,3000,1)))
+NVL(LENGTHB(TO_CHAR(DBM??S_LOB.SUBSTR(<CLOB-Column>,3000,3001))),0)
+NVL(LENGTHB(TO_CHAR(DBM??S_LOB.SUBSTR(<CLOB-Column>,6000,6001))),0)
+...

where you add as many chunks as you need to cover your longest CLOB, and adjust the chunk size according to average bytes-per-character of your data.

Why not using: { position: fixed; bottom: 0 } ?

You can Try this, After starting Service of elasticsearch Type below line in your browser.

         localhost:9200

     It will give Output Something like that,

          {
           "status" : 200,
           "name" : "Hypnotia",
           "cluster_name" : "elasticsearch",
           "version" : {
           "number" : "1.7.1",
           "build_hash" : "b88f43fc40b0bcd7f173a1f9ee2e97816de80b19",
           "build_timestamp" : "2015-07-29T09:54:16Z",
           "build_snapshot" : false,
            "lucene_version" : "4.10.4"
                  },
            "tagline" : "You Know, for Search"
                  }

I'm not sure I quite understand the question but if you want to search objects on the database for a particular search string try:

SELECT owner, name, type, line, text 
FROM dba_source
WHERE instr(UPPER(text), UPPER(:srch_str)) > 0;

From there if you need any more info you can just look up the object / line number.

You can also get an updated version of the Eclipse's ADT plugin (based on an unreleased 24.2.0 version) that I managed to patch and compile at https://github.com/khaledev/ADT.

Double check your text with the Hex Editor Plug-in. In your case there may have been some control characters which have crept into your text. Usually you'll look at the white-space, and it will say 32 32 32 32, or for Unicode 32 00 32 00 32 00 32 00. You may find the problem this way, providing there isn't masses of code.

Download the Hex Plugin from here; http://sourceforge.net/projects/npp-plugins/files/Hex%20Editor/

Try var

var s = new List<string> { "a", "bk", "ca", "d" };

I use the following snippet to view all the rows in a table. Use a query to find all the rows. The returned objects are the class instances. They can be used to view/edit the values as required:

from sqlalchemy.ext.declarative import declarative_base
from sqlalchemy import create_engine, Sequence
from sqlalchemy import String, Integer, Float, Boolean, Column
from sqlalchemy.orm import sessionmaker

Base = declarative_base()

class MyTable(Base):
    __tablename__ = 'MyTable'
    id = Column(Integer, Sequence('user_id_seq'), primary_key=True)
    some_col = Column(String(500))

    def __init__(self, some_col):
        self.some_col = some_col

engine = create_engine('sqlite:///sqllight.db', echo=True)
Session = sessionmaker(bind=engine)
session = Session()

for class_instance in session.query(MyTable).all():
    print(vars(class_instance))

session.close()

1- Select LinearLayout findViewById

LinearLayout llayout =(LinearLayout) findViewById(R.id.llayoutId); 

2- Set color from R.color.colorId

llayout.setBackgroundColor(getResources().getColor(R.color.colorId));

No, it is not possible to reverse a hash function such as MD5: given the output hash value it is impossible to find the input message unless enough information about the input message is known.

Decryption is not a function that is defined for a hash function; encryption and decryption are functions of a cipher such as AES in CBC mode; hash functions do not encrypt nor decrypt. Hash functions are used to digest an input message. As the name implies there is no reverse algorithm possible by design.

MD5 has been designed as a cryptographically secure, one-way hash function. It is now easy to generate collisions for MD5 - even if a large part of the input message is pre-determined. So MD5 is officially broken and MD5 should not be considered a cryptographically secure hash anymore. It is however still impossible to find an input message that leads to a hash value: find X when only H(X) is known (and X doesn't have a pre-computed structure with at least one 128 byte block of precomputed data). There are no known pre-image attacks against MD5.

It is generally also possible to guess passwords using brute force or (augmented) dictionary attacks, to compare databases or to try and find password hashes in so called rainbow tables. If a match is found then it is computationally certain that the input has been found. Hash functions are also secure against collision attacks: finding X' so that H(X') = H(X) given H(X). So if an X is found it is computationally certain that it was indeed the input message. Otherwise you would have performed a collision attack after all. Rainbow tables can be used to speed up the attacks and there are specialized internet resources out there that will help you find a password given a specific hash.

It is of course possible to re-use the hash value H(X) to verify passwords that were generated on other systems. The only thing that the receiving system has to do is to store the result of a deterministic function F that takes H(X) as input. When X is given to the system then H(X) and therefore F can be recalculated and the results can be compared. In other words, it is not required to decrypt the hash value to just verify that a password is correct, and you can still store the hash as a different value.

Instead of MD5 it is important to use a password hash or PBKDF (password based key derivation function) instead. Such a function specifies how to use a salt together with a hash. That way identical hashes won't be generated for identical passwords (from other users or within other databases). Password hashes for that reason also do not allow rainbow tables to be used as long as the salt is large enough and properly randomized.

Password hashes also contain a work factor (sometimes configured using an iteration count) that can significantly slow down attacks that try to find the password given the salt and hash value. This is important as the database with salts and hash values could be stolen. Finally, the password hash may also be memory-hard so that a significant amount of memory is required to calculate the hash. This makes it impossible to use special hardware (GPU's, ASIC's, FPGA's etc.) to allow an attacker to speed up the search. Other inputs or configuration options such as a pepper or the amount of parallelization may also be available to a password hash.

It will however still allow anybody to verify a password given H(X) even if H(X) is a password hash. Password hashes are still deterministic, so if anybody has knows all the input and the hash algorithm itself then X can be used to calculate H(X) and - again - the results can be compared.

Commonly used password hashes are bcrypt, scrypt and PBKDF2. There is also Argon2 in various forms which is the winner of the reasonably recent password hashing competition. Here on CrackStation is a good blog post on doing password security right.

It is possible to make it impossible for adversaries to perform the hash calculation verify that a password is correct. For this a pepper can be used as input to the password hash. Alternatively, the hash value can of course be encrypted using a cipher such as AES and a mode of operation such as CBC or GCM. This however requires the storage of a secret / key independently and with higher access requirements than the password hash.

I made my own subversion repository on my Ubuntu One folder. Then, I imported the files to the repository using svn+ssh and my user account password.

When I want to do a checkout, I just checkout from my Ubuntu One folder. The commit process its analogue.

You must setup Ubutnu One on the devices that you want to grant access, then checkout the project from this folder to a temporary folder to edit it.

In my case, I use a folder in the Ubuntu One file-system, so I have the repository and my develop-folder in Ubuntu One.

Just simply.. #sometime when larger table we can't add the id to each tr

     <table>
        <tr>
            <td>some text</td>
            <td>something</td>
        </tr>
        <tr>
            <td>Hello</td>
            <td>Hel</td>
        </tr>
    </table>

    <script>
        var cell = document.getElementsByTagName("td"); 
        var i = 0;
        while(cell[i] != undefined){
            alert(cell[i].innerHTML); //do some alert for test
            i++;
            }//end while
    </script>

The method jQuery (v1.10) uses to find this is:

var doc = document.documentElement;
var left = (window.pageXOffset || doc.scrollLeft) - (doc.clientLeft || 0);
var top = (window.pageYOffset || doc.scrollTop)  - (doc.clientTop || 0);

That is:

• It tests for window.pageXOffset first and uses that if it exists.
• Otherwise, it uses document.documentElement.scrollLeft.
• It then subtracts document.documentElement.clientLeft if it exists.

The subtraction of document.documentElement.clientLeft / Top only appears to be required to correct for situations where you have applied a border (not padding or margin, but actual border) to the root element, and at that, possibly only in certain browsers.

This is a little outdated, by Ryan Bigg does a great job explaining this here:

http://ryanbigg.com/2009/04/how-rails-works-2-mime-types-respond_to

In fact, it might be a bit more detail than you were looking for. As it turns out, there's a lot going on behind the scenes, including a need to understand how the MIME types get loaded.

According to the Apache Tomcat docs, you can change the application by creating a ROOT.xml file. See this for more info:

http://tomcat.apache.org/tomcat-6.0-doc/config/context.html

"The default web application may be defined by using a file called ROOT.xml."

You need to quote that filename:

f = open("D\\python\\HW\\2_1 - Copy.cp", "r")

Otherwise the bare backslash after the D is interpreted as a line-continuation character, and should be followed by a newline. This is used to extend long expressions over multiple lines, for readability:

print "This is a long",\
      "line of text",\
      "that I'm printing."

Also, you shouldn't have semicolons (;) at the end of your statements in Python.

If you are copying to GitHub, you may use the GitHub Importer to do that for you. The original repo can even be from other version control systems.

Would not that have to be:

.replaceAll("\"","\\\\\"")

FIVE backslashes in the replacement String.

You didn't close the file after creating it, so when you write to it, it's in use by yourself. The Create method opens the file and returns a FileStream object. You either write to the file using the FileStream or close it before writing to it. I would suggest that you use the CreateText method instead in this case, as it returns a StreamWriter.

You also forgot to close the StreamWriter in the case where the file didn't exist, so it would most likely still be locked when you would try to write to it the next time. And you forgot to write the error message to the file if it didn't exist.

Dim strFile As String = "C:\ErrorLog_" & DateTime.Today.ToString("dd-MMM-yyyy") & ".txt"
Dim sw As StreamWriter
Try
   If (Not File.Exists(strFile)) Then
      sw = File.CreateText(strFile)
      sw.WriteLine("Start Error Log for today")
   Else
      sw = File.AppendText(strFile)
   End If
   sw.WriteLine("Error Message in  Occured at-- " & DateTime.Now)
   sw.Close()
Catch ex As IOException
   MsgBox("Error writing to log file.")
End Try

Note: When you catch exceptions, don't catch the base class Exception, catch only the ones that are releveant. In this case it would be the ones inheriting from IOException.

First of all you should stop using mysql_*. MySQL supports multiple inserting like

INSERT INTO example
VALUES
  (100, 'Name 1', 'Value 1', 'Other 1'),
  (101, 'Name 2', 'Value 2', 'Other 2'),
  (102, 'Name 3', 'Value 3', 'Other 3'),
  (103, 'Name 4', 'Value 4', 'Other 4');

You just have to build one string in your foreach loop which looks like that

$values = "(100, 'Name 1', 'Value 1', 'Other 1'), (100, 'Name 1', 'Value 1', 'Other 1'), (100, 'Name 1', 'Value 1', 'Other 1')";

and then insert it after the loop

$sql = "INSERT INTO email_list (R_ID, EMAIL, NAME) VALUES ".$values;

Another way would be Prepared Statements, which are even more suited for your situation.

There is also this project that does the job and worked perfectly for me: https://github.com/chrisbanes/PhotoView

After a long research, we found a solution.

We had set permissions as:

loginButton.setReadPermissions(public_profile email);

This worked for the first time, but when we re-logged in to Facebook, it gave the Invalid Hash Error.

The simple solution was to change the above line to:

loginButton.setReadPermissions(Arrays.asList("public_profile", "email"));

And it worked like a bliss!

Facebook should return the correct exception instead of the misleading invalid hash key error.

try this one :

public void itemClicked(View v) {
  //code to check if this checkbox is checked!
  CheckBox checkBox = (CheckBox)v;
  if(checkBox.isChecked()){

  }
}

You want to look at the patch() function, and sneak in points for the start and end of the horizontal line:

x = 0:.1:2*pi;
y = sin(x)+rand(size(x))/2;

x2 = [0 x 2*pi];
y2 = [.1 y .1];
patch(x2, y2, [.8 .8 .1]);

If you only want the filled in area for a part of the data, you'll need to truncate the x and y vectors to only include the points you need.

I would recommend you using the Conditional Attribute!

Update: 3.5 years later

You can use #if like this (example copied from MSDN):

// preprocessor_if.cs
#define DEBUG
#define VC_V7
using System;
public class MyClass 
{
    static void Main() 
    {
#if (DEBUG && !VC_V7)
        Console.WriteLine("DEBUG is defined");
#elif (!DEBUG && VC_V7)
        Console.WriteLine("VC_V7 is defined");
#elif (DEBUG && VC_V7)
        Console.WriteLine("DEBUG and VC_V7 are defined");
#else
        Console.WriteLine("DEBUG and VC_V7 are not defined");
#endif
    }
}

Only useful for excluding parts of methods.

If you use #if to exclude some method from compilation then you will have to exclude from compilation all pieces of code which call that method as well (sometimes you may load some classes at runtime and you cannot find the caller with "Find all references"). Otherwise there will be errors.

If you use conditional compilation on the other hand you can still leave all pieces of code that call the method. All parameters will still be validated by the compiler. The method just won't be called at runtime. I think that it is way better to hide the method just once and not have to remove all the code that calls it as well. You are not allowed to use the conditional attribute on methods which return value - only on void methods. But I don't think this is a big limitation because if you use #if with a method that returns a value you have to hide all pieces of code that call it too.

Here is an example:

    // calling Class1.ConditionalMethod() will be ignored at runtime 
    // unless the DEBUG constant is defined


    using System.Diagnostics;
    class Class1 
    {
       [Conditional("DEBUG")]
       public static void ConditionalMethod() {
          Console.WriteLine("Executed Class1.ConditionalMethod");
       }
    }

Summary:

I would use #ifdef in C++ but with C#/VB I would use Conditional attribute. This way you hide the method definition without having to hide the pieces of code that call it. The calling code is still compiled and validated by the compiler, the method is not called at runtime though. You may want to use #if to avoid dependencies because with Conditional attribute your code is still compiled.

If you are building the array once and want to find the maximum just once, iterating is the best you can do.

When you want to modify the array and occasionally want to know the maximum element, you should use a Priority Queue. One of the best data structures for that is a Fibonacci Heap, if this is too complicated use a Binary Heap which is slower but still good.

To find minimum and maximum, just build two heaps and change the sign of the numbers in one of them.

That's because you are dealing with floating point numbers. Division by zero returns Infinity, which is similar to NaN (not a number).

If you want to prevent this, you have to test tab[i] before using it. Then you can throw your own exception, if you really need it.

On SQL 2017 - Database A has synonyms to Database B. User can connect to database A and has exec rights to an sp (on A) that refers to the synonyms that point to B. User was set up with connect access B. Only when granting CONNECT to the public group to database B did the sp on A work. I don't recall this working this way on 2012 as granting connect to the user only seemed to work.

The second part of your question is answered well. Here is the answer for the first part: How to output multiple files with webpack:

    entry: {
            outputone: './source/fileone.jsx',
            outputtwo: './source/filetwo.jsx'
            },
    output: {
            path: path.resolve(__dirname, './wwwroot/js/dist'),
            filename: '[name].js'      
            },

This will generate 2 files: outputone.js und outputtwo.js in the target folder.

Available fonts (as of Oreo)

The Material Design Typography page has demos for some of these fonts and suggestions on choosing fonts and styles.

For code sleuths: fonts.xml is the definitive and ever-expanding list of Android fonts.

Using these fonts

Set the android:fontFamily and android:textStyle attributes, e.g.

<!-- Roboto Bold -->
<TextView
    android:fontFamily="sans-serif"
    android:textStyle="bold" />

to the desired values from this table:

Font                     | android:fontFamily          | android:textStyle
-------------------------|-----------------------------|-------------------
Roboto Thin              | sans-serif-thin             |
Roboto Light             | sans-serif-light            |
Roboto Regular           | sans-serif                  |
Roboto Bold              | sans-serif                  | bold
Roboto Medium            | sans-serif-medium           |
Roboto Black             | sans-serif-black            |
Roboto Condensed Light   | sans-serif-condensed-light  |
Roboto Condensed Regular | sans-serif-condensed        |
Roboto Condensed Medium  | sans-serif-condensed-medium |
Roboto Condensed Bold    | sans-serif-condensed        | bold
Noto Serif               | serif                       |
Noto Serif Bold          | serif                       | bold
Droid Sans Mono          | monospace                   |
Cutive Mono              | serif-monospace             |
Coming Soon              | casual                      |
Dancing Script           | cursive                     |
Dancing Script Bold      | cursive                     | bold
Carrois Gothic SC        | sans-serif-smallcaps        |

(Noto Sans is a fallback font; you can't specify it directly)

Note: this table is derived from fonts.xml. Each font's family name and style is listed in fonts.xml, e.g.

<family name="serif-monospace">
    <font weight="400" style="normal">CutiveMono.ttf</font>
</family>

serif-monospace is thus the font family, and normal is the style.

Compatibility

Based on the log of fonts.xml and the former system_fonts.xml, you can see when each font was added:

• Ice Cream Sandwich: Roboto regular, bold, italic, and bold italic
• Jelly Bean: Roboto light, light italic, condensed, condensed bold, condensed italic, and condensed bold italic
• Jelly Bean MR1: Roboto thin and thin italic
• Lollipop:
  • Roboto medium, medium italic, black, and black italic
  • Noto Serif regular, bold, italic, bold italic
  • Cutive Mono
  • Coming Soon
  • Dancing Script
  • Carrois Gothic SC
  • Noto Sans
• Oreo MR1: Roboto condensed medium

If you are on Windows using SMTP, you can use error_get_last() when mail() returns false. Keep in mind this does not work with PHP's native mail() function.

$success = mail('[email protected]', 'My Subject', $message);
if (!$success) {
    $errorMessage = error_get_last()['message'];
}

With print_r(error_get_last()), you get something like this:

[type] => 2
[message] => mail(): Failed to connect to mailserver at "x.x.x.x" port 25, verify your "SMTP" and "smtp_port" setting in php.ini or use ini_set()
[file] => C:\www\X\X.php
[line] => 2

I think one of the original questions here was not answered. I believe that vanilla eval() is not used because then angular apps would not work as Chrome apps, which explicitly prevent eval() from being used for security reasons.

I always just convert a matrix:

x <- as.data.frame(matrix(nrow = 100, ncol = 10))

Maxdepth

I found it works nicely with Jim Lewis's answer just add a bit like this:

$ export DIR=/path/dir && cd $DIR && chmod -R +x *
$ find . -maxdepth 1 -type f -name '*.sh' -exec {} \; > results.out

Sort Order

If you want to execute in sort order, modify it like this:

$ export DIR=/path/dir && cd $DIR && chmod -R +x *
find . -maxdepth 2 -type f -name '*.sh' | sort | bash > results.out

Just for an example, this will execute with following order:

bash: 1: ./assets/main.sh
bash: 2: ./builder/clean.sh
bash: 3: ./builder/concept/compose.sh
bash: 4: ./builder/concept/market.sh
bash: 5: ./builder/concept/services.sh
bash: 6: ./builder/curl.sh
bash: 7: ./builder/identity.sh
bash: 8: ./concept/compose.sh
bash: 9: ./concept/market.sh
bash: 10: ./concept/services.sh
bash: 11: ./product/compose.sh
bash: 12: ./product/market.sh
bash: 13: ./product/services.sh
bash: 14: ./xferlog.sh

Unlimited Depth

If you want to execute in unlimited depth by certain condition, you can use this:

export DIR=/path/dir && cd $DIR && chmod -R +x *
find . -type f -name '*.sh' | sort | bash > results.out

then put on top of each files in the child directories like this:

#!/bin/bash
[[ "$(dirname `pwd`)" == $DIR ]] && echo "Executing `realpath $0`.." || return

and somewhere in the body of parent file:

if <a condition is matched>
then
    #execute child files
    export DIR=`pwd`
fi

You can avoid the BasicResponseHandler, but use the HttpResponse itself to get both status and response as a String.

HttpResponse response = httpClient.execute(get);

// Getting the status code.
int statusCode = response.getStatusLine().getStatusCode();

// Getting the response body.
String responseBody = EntityUtils.toString(response.getEntity());

You could use createElement() method for creating that textbox

First install the Angular/cli globally in machine. to install the angular/cli run the command npm install -g @angular/cli

Above Angular7 , use these two commands to know the version of Angular/Cli 1. ng --version, 2.ng version

Thank you @hobodave.

However I found two weaknesses in your code. Your parsing of the original url to get the "host" segment stops at the first single slash. This presumes that all relative links start in the root directory. This only true sometimes.

original url   :  http://example.com/game/index.html
href in <a> tag:  highscore.html
author's intent:  http://example.com/game/highscore.html  <-200->
crawler result :  http://example.com/highscore.html       <-404->

fix this by breaking at the last single slash not the first

a second unrelated bug, is that $depth does not really track recursion depth, it tracks breadth of the first level of recursion.

If I believed this page were in active use I might debug this second issue, but I suspect the text I am writing now will never be read by anyone, human or robot, since this issue is six years old and I do not even have enough reputation to notify +hobodave directly about these defects by commmenting on his code. Thanks anyway hobodave.

Surprise! You can use split to split.

var parts = "1234567890 ".split(/(.{2})/).filter(O=>O)

Results in [ '12', '34', '56', '78', '90', ' ' ]

In typescript it is possible to do an instanceof check in an if statement and you will have access to the same variable with the Typed properties.

So let's say MarkerSymbolInfo has a property on it called marker. You can do the following:

if (symbolInfo instanceof MarkerSymbol) {
    // access .marker here
    const marker = symbolInfo.marker
}

It's a nice little trick to get the instance of a variable using the same variable without needing to reassign it to a different variable name.

TypeScript instanceof & JavaScript instanceof

Here is a kind of snippet for you:

app.factory('Session', function($http) {
  var Session = {
    data: {},
    saveSession: function() { /* save session data to db */ },
    updateSession: function() { 
      /* load data from db */
      $http.get('session.json').then(function(r) { return Session.data = r.data;});
    }
  };
  Session.updateSession();
  return Session; 
});

Here is Plunker example how you can use that: http://plnkr.co/edit/Fg3uF4ukl5p88Z0AeQqU?p=preview

I guess it depends what language you are targeting. In general, something like this should work:

[^<>%$]

The "[]" construct defines a character class, which will match any of the listed characters. Putting "^" as the first character negates the match, ie: any character OTHER than one of those listed.

You may need to escape some of the characters within the "[]", depending on what language/regex engine you are using.

That is the function that I used for my project, and it works as expected.

function array_csv_download( $array, $filename = "export.csv", $delimiter=";" )
{
    header( 'Content-Type: application/csv' );
    header( 'Content-Disposition: attachment; filename="' . $filename . '";' );

    // clean output buffer
    ob_end_clean();

    $handle = fopen( 'php://output', 'w' );

    // use keys as column titles
    fputcsv( $handle, array_keys( $array['0'] ) );

    foreach ( $array as $value ) {
        fputcsv( $handle, $value , $delimiter );
    }

    fclose( $handle );

    // flush buffer
    ob_flush();

    // use exit to get rid of unexpected output afterward
    exit();
}

I ran into this issue when we changed to Visual Studio 2015. None of the above answers worked for us. In the end we got it working by adding the following config file to ALL sgen.exe executables on the machine

<?xml version ="1.0"?>
    <configuration>
        <startup useLegacyV2RuntimeActivationPolicy="true">
            <supportedRuntime version="v4.0" />
        </startup>    
</configuration>

Particularly in this location, even when we were targeting .NET 4.0:

C:\Program Files (x86)\Microsoft SDKs\Windows\v10.0A\bin\NETFX 4.6 Tools

I found very good explanation about .la files here http://openbooks.sourceforge.net/books/wga/dealing-with-libraries.html

Summary (The way I understood): Because libtool deals with static and dynamic libraries internally (through --diable-shared or --disable-static) it creates a wrapper on the library files it builds. They are treated as binary library files with in libtool supported environment.

Just put quotes around the Environment variable (as you have done) :
if "%DevEnvDir%" == "C:\Program Files (x86)\Microsoft Visual Studio 10.0\Common7\IDE\"
but it's the way you put opening bracket without a space that is confusing it.

Works for me...

C:\if "%gtk_basepath%" == "C:\Program Files\GtkSharp\2.12\" (echo yes)
yes

I have used Nils' answer but converted to more flexible.

public enum SelectAllMode
{

    /// <summary>
    ///  On first focus, it selects all then leave off textbox and doesn't check again
    /// </summary>
    OnFirstFocusThenLeaveOff = 0,

    /// <summary>
    ///  On first focus, it selects all then never selects
    /// </summary>
    OnFirstFocusThenNever = 1,

    /// <summary>
    /// Selects all on every focus
    /// </summary>
    OnEveryFocus = 2,

    /// <summary>
    /// Never selects text (WPF's default attitude)
    /// </summary>
    Never = 4,
}

public partial class TextBox : DependencyObject
{
    public static readonly DependencyProperty SelectAllModeProperty = DependencyProperty.RegisterAttached(
        "SelectAllMode",
        typeof(SelectAllMode?),
        typeof(TextBox),
        new PropertyMetadata(SelectAllModePropertyChanged));

    private static void SelectAllModePropertyChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        if (d is System.Windows.Controls.TextBox)
        {
            var textBox = d as System.Windows.Controls.TextBox;

            if (e.NewValue != null)
            {
                textBox.GotKeyboardFocus += OnKeyboardFocusSelectText;
                textBox.PreviewMouseLeftButtonDown += OnMouseLeftButtonDown;
            }
            else
            {
                textBox.GotKeyboardFocus -= OnKeyboardFocusSelectText;
                textBox.PreviewMouseLeftButtonDown -= OnMouseLeftButtonDown;
            }
        }
    }

    private static void OnMouseLeftButtonDown(object sender, MouseButtonEventArgs e)
    {
        DependencyObject dependencyObject = GetParentFromVisualTree(e.OriginalSource);

        if (dependencyObject == null)
            return;

        var textBox = (System.Windows.Controls.TextBox)dependencyObject;
        if (!textBox.IsKeyboardFocusWithin)
        {
            textBox.Focus();

        {

        }

        return parent;
    }

        var textBox = e.OriginalSource as System.Windows.Controls.TextBox;
        if (textBox == null) return;

        var selectAllMode = GetSelectAllMode(textBox);

        if (selectAllMode == SelectAllMode.Never)
        {
            textBox.SelectionStart = 0;
            textBox.SelectionLength = 0;
        }
        else
            textBox.SelectAll();

        if (selectAllMode == SelectAllMode.OnFirstFocusThenNever)
            SetSelectAllMode(textBox, SelectAllMode.Never);
        else if (selectAllMode == SelectAllMode.OnFirstFocusThenLeaveOff)
            SetSelectAllMode(textBox, null);
    }

    [AttachedPropertyBrowsableForChildrenAttribute(IncludeDescendants = false)]
    [AttachedPropertyBrowsableForType(typeof(System.Windows.Controls.TextBox))]
    public static SelectAllMode? GetSelectAllMode(DependencyObject @object)
    {
        return (SelectAllMode)@object.GetValue(SelectAllModeProperty);
    }

    public static void SetSelectAllMode(DependencyObject @object, SelectAllMode? value)
    {
        @object.SetValue(SelectAllModeProperty, value);
    }
}

In XAML, you can use like one of these:

<!-- On first focus, it selects all then leave off textbox and doesn't check again -->
<TextBox attprop:TextBox.SelectAllMode="OnFirstFocusThenLeaveOff" />

<!-- On first focus, it selects all then never selects -->
<TextBox attprop:TextBox.SelectAllMode="OnFirstFocusThenNever" />

<!-- Selects all on every focus -->
<TextBox attprop:TextBox.SelectAllMode="OnEveryFocus" />

<!-- Never selects text (WPF's default attitude) -->
<TextBox attprop:TextBox.SelectAllMode="Never" />

Your regular expression [^a-zA-Z0-9]\s/g says match any character that is not a number or letter followed by a space.

Remove the \s and you should get what you are after if you want a _ for every special character.

var newString = str.replace(/[^A-Z0-9]/ig, "_");

That will result in hello_world___hello_universe

If you want it to be single underscores use a + to match multiple

var newString = str.replace(/[^A-Z0-9]+/ig, "_");

That will result in hello_world_hello_universe

An oblique answer to the question is to write all the code as classes, apart from the index.php files, which are then the only points of entry. PHP files that contain classes will not cause anything to happen, even if they are invoked directly through Apache.

A direct answer is to include the following in .htaccess:

<FilesMatch "\.php$">
    Order Allow,Deny
    Deny from all
</FilesMatch>
<FilesMatch "index[0-9]?\.php$">
    Order Allow,Deny
    Allow from all
</FilesMatch>

This will allow any file like index.php, index2.php etc to be accessed, but will refuse access of any kind to other .php files. It will not affect other file types.

Just to build on vinnief's hacky solution above, I use MsgBox like this:

Browser.msgBox('BorderoToMatriz', Browser.Buttons.OK_CANCEL);

and it acts kinda like a break point, stops the script and outputs whatever string you need to a pop-up box. I find especially in Sheets, where I have trouble with Logger.log, this provides an adequate workaround most times.

If anyone wonders how to this for clustermap CorrGrids (part of a given seaborn example):

import seaborn as sns
import matplotlib.pyplot as plt
sns.set(context="paper", font="monospace")

# Load the datset of correlations between cortical brain networks
df = sns.load_dataset("brain_networks", header=[0, 1, 2], index_col=0)
corrmat = df.corr()

# Set up the matplotlib figure
f, ax = plt.subplots(figsize=(12, 9))

# Draw the heatmap using seaborn
g=sns.clustermap(corrmat, vmax=.8, square=True)
rotation = 90 
for i, ax in enumerate(g.fig.axes):   ## getting all axes of the fig object
     ax.set_xticklabels(ax.get_xticklabels(), rotation = rotation)


g.fig.show()
