Welcome to Java! This Nodes are like a blocks, they must be assembled to do amazing things! In this particular case, your nodes can represent a list, a linked list, You can see an example here:

public class ItemLinkedList {
    private ItemInfoNode head;
    private ItemInfoNode tail;
    private int size = 0;

    public int getSize() {
        return size;
    }

    public void addBack(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, null, tail);
            this.tail.next =node;
            this.tail = node;
        }
    }

    public void addFront(ItemInfo info) {
        size++;
        if (head == null) {
            head = new ItemInfoNode(info, null, null);
            tail = head;
        } else {
            ItemInfoNode node = new ItemInfoNode(info, head, null);
            this.head.prev = node;
            this.head = node;
        }
    }

    public ItemInfo removeBack() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = tail.info;
            if (tail.prev != null) {
                tail.prev.next = null;
                tail = tail.prev;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public ItemInfo removeFront() {
        ItemInfo result = null;
        if (head != null) {
            size--;
            result = head.info;
            if (head.next != null) {
                head.next.prev = null;
                head = head.next;
            } else {
                head = null;
                tail = null;
            }
        }
        return result;
    }

    public class ItemInfoNode {

        private ItemInfoNode next;
        private ItemInfoNode prev;
        private ItemInfo info;

        public ItemInfoNode(ItemInfo info, ItemInfoNode next, ItemInfoNode prev) {
            this.info = info;
            this.next = next;
            this.prev = prev;
        }

        public void setInfo(ItemInfo info) {
            this.info = info;
        }

        public void setNext(ItemInfoNode node) {
            next = node;
        }

        public void setPrev(ItemInfoNode node) {
            prev = node;
        }

        public ItemInfo getInfo() {
            return info;
        }

        public ItemInfoNode getNext() {
            return next;
        }

        public ItemInfoNode getPrev() {
            return prev;
        }
    }
}

EDIT:

Declare ItemInfo as this:

public class ItemInfo {
    private String name;
    private String rfdNumber;
    private double price;
    private String originalPosition;

    public ItemInfo(){
    }

    public ItemInfo(String name, String rfdNumber, double price, String originalPosition) {
        this.name = name;
        this.rfdNumber = rfdNumber;
        this.price = price;
        this.originalPosition = originalPosition;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getRfdNumber() {
        return rfdNumber;
    }

    public void setRfdNumber(String rfdNumber) {
        this.rfdNumber = rfdNumber;
    }

    public double getPrice() {
        return price;
    }

    public void setPrice(double price) {
        this.price = price;
    }

    public String getOriginalPosition() {
        return originalPosition;
    }

    public void setOriginalPosition(String originalPosition) {
        this.originalPosition = originalPosition;
    }
}

Then, You can use your nodes inside the linked list like this:

public static void main(String[] args) {
    ItemLinkedList list = new ItemLinkedList();
    for (int i = 1; i <= 10; i++) {
        list.addBack(new ItemInfo("name-"+i, "rfd"+i, i, String.valueOf(i)));

    }
    while (list.size() > 0){
        System.out.println(list.removeFront().getName());
    }
}

"hello _there_".replace(/_(.*?)_/, function(a, b){
    return '<div>' + b + '</div>';
})

Oh, or you could also:

"hello _there_".replace(/_(.*?)_/, "<div>$1</div>")

EDIT by Liran H: For six other people including myself, $1 did not work, whereas \1 did.

You can set a reference to the Scripting.Runtime library and then use the FileSystemObject. It has a DeleteFile method and a FileExists method.

See the MSDN article here.

The problem for me was, I had taken backup of controller (js) file with some other changes in the same folder and bundling loaded both the controller files (original and backup js). Removing backup from the scripts folder, that was bundled solved the issue.

That syntax should work OK, but you can try this alternative.

<a href="javascript:void(0);" onclick="ShowOld(2367,146986,2);">

or

<a href="javascript:ShowOld(2367, 146986, 2);">

UPDATED ANSWER FOR STRING VALUES

If you are passing strings, use single quotes for your function's parameters

<a href="javascript:ShowOld('foo', 146986, 'bar');">

This will also work on iOS:

<input type="text" onclick="this.focus(); this.setSelectionRange(0, 9999);" />

It's something in the way jQuery translates to IE8, not necessarily the browser itself.

I was able to work around by going old school and breaking out of jQuery for one line:

document.getElementById('myselect').selectedIndex = -1;

Minor improvements to @Alex's answer that enables updating of dictionaries of differing depths as well as limiting the depth that the update dives into the original nested dictionary (but the updating dictionary depth is not limited). Only a few cases have been tested:

def update(d, u, depth=-1):
    """
    Recursively merge or update dict-like objects. 
    >>> update({'k1': {'k2': 2}}, {'k1': {'k2': {'k3': 3}}, 'k4': 4})
    {'k1': {'k2': {'k3': 3}}, 'k4': 4}
    """

    for k, v in u.iteritems():
        if isinstance(v, Mapping) and not depth == 0:
            r = update(d.get(k, {}), v, depth=max(depth - 1, -1))
            d[k] = r
        elif isinstance(d, Mapping):
            d[k] = u[k]
        else:
            d = {k: u[k]}
    return d

I got the following error:

org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here
    at org.springframework.orm.hibernate3.SpringSessionContext.currentSession(SpringSessionContext.java:63)

I fixed this by changing my hibernate properties file

hibernate.current_session_context_class=thread

My code and configuration file as follows

session =  getHibernateTemplate().getSessionFactory().getCurrentSession();

session.beginTransaction();

session.createQuery(Qry).executeUpdate();

session.getTransaction().commit();

on properties file

hibernate.dialect=org.hibernate.dialect.MySQLDialect

hibernate.show_sql=true

hibernate.query_factory_class=org.hibernate.hql.ast.ASTQueryTranslatorFactory

hibernate.current_session_context_class=thread

on cofiguration file

<properties>
<property name="hibernateProperties">

given your example above - to find processes attached to shmid 98306

lsof | egrep "98306|COMMAND"

Have you tried using Firebug to inspect the rendered HTML, and to see exactly what css is being applied to the various elements? That should pick up css errors like the ones mentioned above, and you can see what styles are being inherited and from where - it is an invaluable too in any css debugging.

You can also do this easily in Pandas, if your data is represented in a Dataframe, as described here:

http://pandas.pydata.org/pandas-docs/version/0.15.0/visualization.html#scatter-plot

ISNULL(
case textcolum1
    WHEN '' THEN NULL
    ELSE textcolum1
END 
,textcolum2) textcolum1

Select First two Character in selected Field with Left(string,Number of Char in int)

SELECT LEFT(FName, 2) AS FirstName FROM dbo.NameMaster

I actually tried to implement connection pooling on the django end using:

https://github.com/gmcguire/django-db-pool

but I still received this error, despite lowering the number of connections available to below the standard development DB quota of 20 open connections.

There is an article here about how to move your postgresql database to the free/cheap tier of Amazon RDS. This would allow you to set max_connections higher. This will also allow you to pool connections at the database level using PGBouncer.

https://www.lewagon.com/blog/how-to-migrate-heroku-postgres-database-to-amazon-rds

UPDATE:

Heroku responded to my open ticket and stated that my database was improperly load balanced in their network. They said that improvements to their system should prevent similar problems in the future. Nonetheless, support manually relocated my database and performance is noticeably improved.

Isn't this maybe the most elegant?

REPLACE 
INTO component_psar (tbl_id, row_nr, col_1, col_2, col_3, col_4, col_5, col_6, unit, add_info, fsar_lock) 
VALUES('2', '1', '1', '1', '1', '1', '1', '1', '1', '1', 'N')

see: http://dev.mysql.com/doc/refman/5.7/en/replace.html

The code works for me. (after adding missing except clause / import statements)

Did you put \ in the original code?

urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/' \
              + stock + '/chartdata;type=quote;range=5d/csv'

If you omit it, it could be a cause of the exception:

>>> stock = 'GOOG'
>>> urlToVisit = 'http://chartapi.finance.yahoo.com/instrument/1.0/'
>>> + stock + '/chartdata;type=quote;range=5d/csv'
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: bad operand type for unary +: 'str'

BTW, string(e) should be str(e).

you can create user and grant privilege

create user read_only identified by read_only; grant create session,select any table to read_only;

You can try to use the following code instead:

 $pro= model_name::where('col_name', '=', 'value')->get();

The explicit way of saying "search until X but not including X" is:

(?:(?!X).)*

where X can be any regular expression.

In your case, though, this might be overkill - here the easiest way would be

[^z]*

This will match anything except z and therefore stop right before the next z.

So .*?quick[^z]* will match The quick fox jumps over the la.

However, as soon as you have more than one simple letter to look out for, (?:(?!X).)* comes into play, for example

(?:(?!lazy).)* - match anything until the start of the word lazy.

This is using a lookahead assertion, more specifically a negative lookahead.

.*?quick(?:(?!lazy).)* will match The quick fox jumps over the.

Explanation:

(?:        # Match the following but do not capture it:
 (?!lazy)  # (first assert that it's not possible to match "lazy" here
 .         # then match any character
)*         # end of group, zero or more repetitions.

Furthermore, when searching for keywords, you might want to surround them with word boundary anchors: \bfox\b will only match the complete word fox but not the fox in foxy.

Note

If the text to be matched can also include linebreaks, you will need to set the "dot matches all" option of your regex engine. Usually, you can achieve that by prepending (?s) to the regex, but that doesn't work in all regex engines (notably JavaScript).

Alternative solution:

In many cases, you can also use a simpler, more readable solution that uses a lazy quantifier. By adding a ? to the * quantifier, it will try to match as few characters as possible from the current position:

.*?(?=(?:X)|$)

will match any number of characters, stopping right before X (which can be any regex) or the end of the string (if X doesn't match). You may also need to set the "dot matches all" option for this to work. (Note: I added a non-capturing group around X in order to reliably isolate it from the alternation)

If you are using VIM version 8+, just type Ctrl + n or Ctrl + p.

Well, you may try this '.*[0-9]'

For those of you who are trying to dump greek or other "exotic" languages such as me but are also having problems (unicode errors) with weird characters such as the peace symbol (\u262E) or others which are often contained in json formated data such as Twitter's, the solution could be as follows (sort_keys is obviously optional):

import codecs, json
with codecs.open('data.json', 'w', 'utf8') as f:
     f.write(json.dumps(data, sort_keys = True, ensure_ascii=False))

You just need to create directory in C:. as C:\data\db\

Now just start mongoDB:

It will then run as service in background.

Have not tested it yet, but the looks are better than the one Alex mentions.

The description at winginx.com/en/htaccess says:

About the htaccess to nginx converter

The service is to convert an Apache's .htaccess to nginx configuration instructions.

First of all, the service was thought as a mod_rewrite to nginx converter. However, it allows you to convert some other instructions that have reason to be ported from Apache to nginx.

Note server instructions (e.g. php_value, etc.) are ignored.

The converter does not check syntax, including regular expressions and logic errors.

Please, check the result manually before use.

A View in Oracle and in other database systems is simply the representation of a SQL statement that is stored in memory so that it can easily be re-used. For example, if we frequently issue the following query

SELECT customerid, customername FROM customers WHERE countryid='US';

To create a view use the CREATE VIEW command as seen in this example

CREATE VIEW view_uscustomers
AS
SELECT customerid, customername FROM customers WHERE countryid='US';

This command creates a new view called view_uscustomers. Note that this command does not result in anything being actually stored in the database at all except for a data dictionary entry that defines this view. This means that every time you query this view, Oracle has to go out and execute the view and query the database data. We can query the view like this:

SELECT * FROM view_uscustomers WHERE customerid BETWEEN 100 AND 200;

And Oracle will transform the query into this:

SELECT * 
FROM (select customerid, customername from customers WHERE countryid='US') 
WHERE customerid BETWEEN 100 AND 200

Benefits of using Views

• Commonality of code being used. Since a view is based on one common set of SQL, this means that when it is called it’s less likely to require parsing.
• Security. Views have long been used to hide the tables that actually contain the data you are querying. Also, views can be used to restrict the columns that a given user has access to.
• Predicate pushing

You can find advanced topics in this article about "How to Create and Manage Views in Oracle."

In your onCreate() method:

getWindow().getDecorView().setBackgroundColor(getResources().getColor(R.color.main_activity_background_color));

Also you need to add to values folder a new XML file called color.xml and Assign there a new color property:

color.xml:

<?xml version="1.0" encoding="utf-8"?>
<resources>
<color name="main_activity_background_color">#000000</color>
</resources>

Note that you can name the color.xml any name you want but you refer to it by code as R.color.yourId.

EDIT

Because getResources().getColor() is deprecated, use getWindow().getDecorView().setBackgroundColor(ContextCompat.getColor(MainActivity.this, R.color.main_activity_background_color)); instead.

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

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

Expressions

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

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

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

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

Try this one.

Excerpt from the package description

Package java.util.concurrent.atomic description: A small toolkit of classes that support lock-free thread-safe programming on single variables.[...]

The specifications of these methods enable implementations to employ efficient machine-level atomic instructions that are available on contemporary processors.[...]

Instances of classes AtomicBoolean, AtomicInteger, AtomicLong, and AtomicReference each provide access and updates to a single variable of the corresponding type.[...]

The memory effects for accesses and updates of atomics generally follow the rules for volatiles:

• get has the memory effects of reading a volatile variable.
• set has the memory effects of writing (assigning) a volatile variable.
• weakCompareAndSet atomically reads and conditionally writes a variable, is ordered with respect to other memory operations on that variable, but otherwise acts as an ordinary non-volatile memory operation.
• compareAndSet and all other read-and-update operations such as getAndIncrement have the memory effects of both reading and writing volatile variables.

This means that there is a line which starts with a space, tab, or some other whitespace without having a target in front of it.

Add a column to the left so that B10 to B20 is your named range Age.

Set A10 to A20 so that A10 = 1, A11= 2,... A20 = 11 and give the range A10 to A20 a name e.g. AgeIndex.

The 5th element can be then found by using an array formula:

=sum( Age * (1 * (AgeIndex = 5) )

As it's an array formula you'll need to press Ctrl + Shift + Return to make it work and not just return. Doing that, the formula will be turned into an array formula:

{=sum( Age * (1 * (AgeIndex = 5) )}

Easiest Way in Passing A Variable-Length 2D Array

Most clean technique for both C & C++ is: pass 2D array like a 1D array, then use as 2D inside the function.

#include <stdio.h>

void func(int row, int col, int* matrix){
    int i, j;
    for(i=0; i<row; i++){
        for(j=0; j<col; j++){
            printf("%d ", *(matrix + i*col + j)); // or better: printf("%d ", *matrix++);
        }
        printf("\n");
    }
}

int main(){
    int matrix[2][3] = { {0, 1, 2}, {3, 4, 5} };
    func(2, 3, matrix[0]);

    return 0;
}

_{Internally, no matter how many dimensions an array has, C/C++ always maintains a 1D array. And so, we can pass any multi-dimensional array like this.}

Math.round() returns the nearest integer to your given input value. If your float already has an integer value the "nearest" integer will be that same value, so all you need to do is check whether Math.round() changes the value or not:

if (value == Math.round(value)) {
  System.out.println("Integer");
} else {
  System.out.println("Not an integer");
}

OnClientClick="SomeMethod()" event of that BUTTON, it return by default "true" so after that function it do postback

for solution use

//use this code in BUTTON  ==>   OnClientClick="return SomeMethod();"

//and your function like this
<script type="text/javascript">
  function SomeMethod(){
    // put your code here 
    return false;
  }
</script>

The best way is to run this batch file. open notepad and type:-

@echo off
echo Set oWS = WScript.CreateObject("WScript.Shell") > CreateShortcut.vbs
echo sLinkFile = "GIVETHEPATHOFLINK.lnk" >> CreateShortcut.vbs
echo Set oLink = oWS.CreateShortcut(sLinkFile) >> CreateShortcut.vbs
echo oLink.TargetPath = "GIVETHEPATHOFTARGETFILEYOUWANTTHESHORTCUT" >> CreateShortcut.vbs
echo oLink.Save >> CreateShortcut.vbs
cscript CreateShortcut.vbs
del CreateShortcut.vbs

Save as filename.bat(be careful while saving select all file types) worked well in win XP.

Try getting Spring to inject it, assuming you're using Spring as a dependency-injection framework.

In your class, do something like this:

public void setSqlResource(Resource sqlResource) {
    this.sqlResource = sqlResource;
}

And then in your application context file, in the bean definition, just set a property:

<bean id="someBean" class="...">
    <property name="sqlResource" value="classpath:com/somecompany/sql/sql.txt" />
</bean>

And Spring should be clever enough to load up the file from the classpath and give it to your bean as a resource.

You could also look into PropertyPlaceholderConfigurer, and store all your SQL in property files and just inject each one separately where needed. There are lots of options.

Yes. The only way would be to drop the constraint with an Alter table then recreate it.

ALTER TABLE <Table_Name>
DROP CONSTRAINT <constraint_name>

ALTER TABLE <Table_Name>
ADD CONSTRAINT <constraint_name> PRIMARY KEY (<Column1>,<Column2>)

In my case I was trying to test SSL in my Visual Studio environment using IIS 7.

This is what I ended up doing to get it to work:

• Under my site in the 'Bindings...' section on the right in IIS, I had to add the 'https' binding to port 443 and select "IIS Express Developement Certificate".

• Under my site in the 'Advanced Settings...' section on the right I had to change the 'Enabled Protocols' from "http" to "https".

• Under the 'SSL Settings' icon I selected 'Accept' for client certificates.

• Then I had to recycle the app pool.

• I also had to import the local host certificate into my personal store using mmc.exe.

My web.config file was already configured correctly, so after I got all the above sorted out, I was able to continue my testing.

To expand on Karl's reply, Vim looks in a specific set of directories for its runtime files. You can see that set of directories via :set runtimepath?. In order to tell Vim to also look inside ~/.vim/vim-haml you'll want to add

set runtimepath+=$HOME/.vim/vim-haml

to your ~/.vimrc. You'll likely also want the following in your ~/.vimrc to enable all the functionality provided by vim-haml.

filetype plugin indent on
syntax on

You can refer to the 'runtimepath' and :filetype help topics in Vim for more information.

Instead of command: docker run

You should use:

docker start **CONTAINER ID**

because the container is already exist

When running the python file, you would normally do this

python app.py

To avoid these messsages. Inside the CLI (Command Line Interface), run these commands.

export FLASK_APP=app.py
export FLASK_RUN_HOST=127.0.0.1
export FLASK_ENV=development
export FLASK_DEBUG=0
flask run

This should work perfectlly. :) :)

You can plot the means without resorting to external calculations and additional tables using stat_summary(...). In fact, stat_summary(...) was designed for exactly what you are doing.

library(ggplot2)
library(reshape2)            # for melt(...)
gg <- melt(df,id="gender")   # df is your original table
ggplot(gg, aes(x=variable, y=value, fill=factor(gender))) + 
  stat_summary(fun.y=mean, geom="bar",position=position_dodge(1)) + 
  scale_color_discrete("Gender")
  stat_summary(fun.ymin=min,fun.ymax=max,geom="errorbar",
               color="grey80",position=position_dodge(1), width=.2)

To add "error bars" you cna also use stat_summary(...) (here, I'm using the min and max value rather than sd because you have so little data).

ggplot(gg, aes(x=variable, y=value, fill=factor(gender))) + 
  stat_summary(fun.y=mean, geom="bar",position=position_dodge(1)) + 
  stat_summary(fun.ymin=min,fun.ymax=max,geom="errorbar",
               color="grey40",position=position_dodge(1), width=.2) +
  scale_fill_discrete("Gender")

ComputerDruid's answer is great but I don't think it's necessary to set upstream manually unless you want to. I'm adding this answer because people might think that that's a necessary step.

This error will be gone if you specify the remote that you want to pull like below:

git pull origin master

Note that origin is the name of the remote and master is the branch name.

1) How to check remote's name

git remote -v

2) How to see what branches available in the repository.

git branch -r

Importing file2 in file1.py makes the global (i.e., module level) names bound in file2 available to following code in file1 -- the only such name is SomeClass. It does not do the reverse: names defined in file1 are not made available to code in file2 when file1 imports file2. This would be the case even if you imported the right way (import file2, as @nate correctly recommends) rather than in the horrible, horrible way you're doing it (if everybody under the Sun forgot the very existence of the construct from ... import *, life would be so much better for everybody).

Apparently you want to make global names defined in file1 available to code in file2 and vice versa. This is known as a "cyclical dependency" and is a terrible idea (in Python, or anywhere else for that matter).

So, rather than showing you the incredibly fragile, often unmaintainable hacks to achieve (some semblance of) a cyclical dependency in Python, I'd much rather discuss the many excellent way in which you can avoid such terrible structure.

For example, you could put global names that need to be available to both modules in a third module (e.g. file3.py, to continue your naming streak;-) and import that third module into each of the other two (import file3 in both file1 and file2, and then use file3.foo etc, that is, qualified names, for the purpose of accessing or setting those global names from either or both of the other modules, not barenames).

Of course, more and more specific help could be offered if you clarified (by editing your Q) exactly why you think you need a cyclical dependency (just one easy prediction: no matter what makes you think you need a cyclical dependency, you're wrong;-).

With Spring you can do:

String path = new UrlPathHelper().getPathWithinApplication(request);

To Empty a Current memory location of an array use: 'myArray.length = 0' or 'myArray.pop() UN-till its length is 0'

• length : You can set the length property to truncate an array at any time. When you extend an array by changing its length property, the number of actual elements increases.
• pop() : The pop method removes the last element from an array and returns that returns the removed value.
• shift() : The shift method removes the element at the zeroeth index and shifts the values at consecutive indexes down, then returns the removed value.

Example:

var arr = ['77'];
arr.length = 20;
console.log("Increasing : ", arr); // (20) ["77", empty × 19]
arr.length = 12;
console.log("Truncating : ", arr); // (12) ["77", empty × 11]

var mainArr = new Array();
mainArr = ['1', '2', '3', '4'];

var refArr = mainArr;
console.log('Current', mainArr, 'Refered', refArr);

refArr.length = 3;
console.log('Length: ~ Current', mainArr, 'Refered', refArr);

mainArr.push('0');
console.log('Push to the End of Current Array Memory Location \n~ Current', mainArr, 'Refered', refArr);

mainArr.poptill_length(0);
console.log('Empty Array \n~ Current', mainArr, 'Refered', refArr);

Array.prototype.poptill_length = function (e) {
  while (this.length) {
    if( this.length == e ) break;

    console.log('removed last element:', this.pop());
  }
};

• new Array() | [] Create an Array with new memory location by using Array constructor or array literal.

  mainArr = []; // a new empty array is addressed to mainArr.
  
  var arr = new Array('10'); // Array constructor
  arr.unshift('1'); // add to the front
  arr.push('15'); // add to the end
  console.log("After Adding : ", arr); // ["1", "10", "15"]
  
  arr.pop(); // remove from the end
  arr.shift(); // remove from the front
  console.log("After Removing : ", arr); // ["10"]
  
  var arrLit = ['14', '17'];
  console.log("array literal « ", indexedItem( arrLit ) ); // {0,14}{1,17}
  
  function indexedItem( arr ) {
      var indexedStr = "";
      arr.forEach(function(item, index, array) {
          indexedStr += "{"+index+","+item+"}";
          console.log(item, index);
      });
      return indexedStr;
  }
  

• slice() : By using slice function we get an shallow copy of elements from the original array, with new memory address, So that any modification on cloneArr will not affect to an actual|original array.

  var shallowCopy = mainArr.slice(); // this is how to make a copy
  
  var cloneArr = mainArr.slice(0, 3); 
  console.log('Main', mainArr, '\tCloned', cloneArr);
  
  cloneArr.length = 0; // Clears current memory location of an array.
  console.log('Main', mainArr, '\tCloned', cloneArr);
  

Try this lets say your form id is formID

$(".nextbutton").click(function() { $("form#formID").submit(); });

GitHub for Windows does indeed install its own version of Git, but it doesn't add it to the PATH variable, which is easy enough to do. Here's instructions on how to do it:

1. Get the Git URL

   We need to get the url of the Git \cmd directory your computer. Git is located here:

   C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\cmd\git.exe
   

   So on your computer, replace <user> with your user and find out what the <guid> is for your computer. (The guid may change each time GitHub updates PortableGit, but they're working on a solution to that.)

   Copy it and paste it into a command prompt (right-click > paste to paste in the terminal) to verify that it works. You should see the Git help response that lists common Git commands. If you see The system cannot find the path specified. Then the URL isn’t right. Once you have it right, create the link to the directory using this format:

   ;C:\Users\<user>\AppData\Local\GitHub\PortableGit_<guid>\cmd
   

   (Note: \cmd at the end, not \cmd\git.exe anymore!)

   On my system, it’s this, yours will be different:

   ;C:\Users\brenton\AppData\Local\GitHub\PortableGit_7eaa494e16ae7b397b2422033as45d8ff6ac2010\cmd
   

2. Edit the PATH Variable

   Navigate to the Environmental Variables Editor (instructions) and find the Path variable in the “System Variables” section. Click Edit… and paste the URL of Git to the end of that string. Save! It might be easier to pull this into Notepad to do the edit, just make sure you put one semicolon before you paste in the URL. If it doesn't work it’s probably because this path got messed up either with a space in there somewhere (should be no spaces around the semicolon) or a semicolon at the end (semicolons should only separate URLs, no semicolon at beginning or end of string).

If it worked, you should be able to close & reopen a terminal and type git and it will give you that same git help file. Then installing the Linter should work. (Atom > File > Settings > Packages > Linter)

If all else fails try moving (i.e. in bash) all files and directories "away" and adding them back one by one.

I just found out that way that my .htaccess file was referencing a non-existant .htpasswd file. (#silly)

Use Son Of Strike which has a command ObjSize.

Note that actual memory consumed is always larger than ObjSize reports due to a synkblk which resides directly before the object data.

In Kotlin, I am using a class DoubleButtonDialog.Java with line window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT)) as important one

class DoubleButtonDialog(context: Context) : Dialog(context, R.style.DialogTheme) {

    private var cancelableDialog: Boolean = true
    private var titleDialog: String? = null
    private var messageDialog: String? = null
    private var leftButtonDialog: String = "Yes"
    //    private var rightButtonDialog: String? = null
    private var onClickListenerDialog: OnClickListener? = null

    override fun onCreate(savedInstanceState: Bundle?) {
        window?.setBackgroundDrawable(ColorDrawable(Color.TRANSPARENT))
        //requestWindowFeature(android.view.Window.FEATURE_NO_TITLE)
        setCancelable(cancelableDialog)
        setContentView(R.layout.dialog_double_button)
//        val btnNegative = findViewById<Button>(R.id.btnNegative)
//        btnNegative.visibility = View.GONE
//        if (rightButtonDialog != null) {
//            btnNegative.visibility = View.VISIBLE
//            btnNegative.text = rightButtonDialog
//            btnNegative.setOnClickListener {
//                dismiss()
//                onClickListenerDialog?.onClickCancel()
//            }
//        }
        val btnPositive = findViewById<Button>(R.id.btnPositive)
        btnPositive.text = leftButtonDialog
        btnPositive.setOnClickListener {
            onClickListenerDialog?.onClick()
            dismiss()
        }
        (findViewById<TextView>(R.id.title)).text = titleDialog
        (findViewById<TextView>(R.id.message)).text = messageDialog
        super.onCreate(savedInstanceState)
    }

    constructor(
        context: Context, cancelableDialog: Boolean, titleDialog: String?,
        messageDialog: String, leftButtonDialog: String, /*rightButtonDialog: String?,*/
        onClickListenerDialog: OnClickListener
    ) : this(context) {
        this.cancelableDialog = cancelableDialog
        this.titleDialog = titleDialog
        this.messageDialog = messageDialog
        this.leftButtonDialog = leftButtonDialog
//        this.rightButtonDialog = rightButtonDialog
        this.onClickListenerDialog = onClickListenerDialog
    }
}


interface OnClickListener {
    //    fun onClickCancel()
    fun onClick()
}

In layout, we can create a dialog_double_button.xml

<body onLoad="self.focus();document.formname.name.focus()" >

formname is <form action="xxx.php" method="POST" name="formname" >

it works for me, checked using IE and mozilla.
autofocus, somehow didn't work for me.

This is simple by using AlertDialog and Intent.ACTION_PICK

    //camOption is a string array contains two items (Camera, Gallery)
    AlertDialog.Builder builder = new AlertDialog.Builder(CarPhotos.this);
    builder.setTitle(R.string.selectSource)
    .setItems(R.array.imgOption, new DialogInterface.OnClickListener() {

    public void onClick(DialogInterface dialog, int which)

     {

        if (which==0) {
        Intent intent = new Intent(this, CameraActivity.class);
        startActivityForResult(intent, REQ_CAMERA_IMAGE);               }

        if (which==1) {
        Intent i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
        startActivityForResult(i, RESULT_LOAD_IMAGE);
            }

     }
            });
             builder.create();
             builder.show();

I know this thread is a bit old, but I came across this thread before I found the answer I was looking for and thought I'd share. If you are using SQLExpress (or localdb) there is a simpler way to find your instance names. At a command line type:

> sqllocaldb i

This will list the instance names you have installed locally. So your full server name should include (localdb)\ in front of the instance name to connect. Also, sqllocaldb allows you to create new instances or delete them as well as configure them. See: SqlLocalDB Utility.

In case of gray image, I am using this function and it works fine! however you must take care about the function features ;)

CvMat * src=  cvCreateMat(300,300,CV_32FC1);      
IplImage *dist= cvCreateImage(cvGetSize(dist),IPL_DEPTH_32F,3);

cvConvertScale(src, dist, 1, 0);

Is there such a thing as destructors for ECMAScript 6?

No. EcmaScript 6 does not specify any garbage collection semantics at all^[1], so there is nothing like a "destruction" either.

If I register some of my object's methods as event listeners in the constructor, I want to remove them when my object is deleted

A destructor wouldn't even help you here. It's the event listeners themselves that still reference your object, so it would not be able to get garbage-collected before they are unregistered.
What you are actually looking for is a method of registering listeners without marking them as live root objects. (Ask your local eventsource manufacturer for such a feature).

_{1): Well, there is a beginning with the specification of WeakMap and WeakSet objects. However, true weak references are still in the pipeline [1][2].}

I thought that PCLint would do this, but it has been a few years since I've looked at it. You might check it out.

I looked at this blog and the author talked a bit about configuring PCLint to find unused includes. Might be worth a look.

If you are developing spring boot application add "SpringBootServletInitializer" as shown in following code to your main file. Because without SpringBootServletInitializer Tomcat will consider it as normal application it will not consider as Spring boot application

@SpringBootApplication
public class DemoApplication extends *SpringBootServletInitializer*{

    @Override
    protected SpringApplicationBuilder configure(SpringApplicationBuilder application) {
         return application.sources(DemoApplication .class);
    }

    public static void main(String[] args) {
         SpringApplication.run(DemoApplication .class, args);
    }
}

TimeZone - Apple Developer Swift Documentation

You could use a regular expression validator on the upload control:

  <asp:RegularExpressionValidator id="FileUpLoadValidator" runat="server" ErrorMessage="Upload Excel files only." ValidationExpression="^(([a-zA-Z]:)|(\\{2}\w+)\$?)(\\(\w[\w].*))(.xls|.XLS|.xlsx|.XLSX)$" ControlToValidate="fileUpload"> </asp:RegularExpressionValidator>

There is also the accept attribute of the input tag:

<input type="file" accept="application/msexcel" id="fileUpload" runat="server">

but I did not have much success when I tried this (with FF3 and IE7)

From a Collection, another way you could do it would be:

$collection->pluck('id')->toArray()

This will return an indexed array, perfectly usable by laravel in a whereIn() query, for instance.

Mini snippet:

var speedtest = {};
function speedTest_start(name) { speedtest[name]= +new Date(); }
function speedTest_stop(name) { return +new Date() - speedtest[name] + (delete 
speedtest[name]?0:0); }

use like:

speedTest_start("test1");

// ... some code

speedTest_stop("test1");
// returns the time duration in ms

Also more tests possible:

speedTest_start("whole");

// ... some code

speedTest_start("part");

// ... some code

speedTest_stop("part");
// returns the time duration in ms of "part"

// ... some code

speedTest_stop("whole");
// returns the time duration in ms of "whole"

Usally, I end up writing a static class with properties to access each of the settings of my web.config.

public static class ConfigManager 
{
    public static string MyBaseDir
    {
        return ConfigurationManager.AppSettings["MyBaseDir"].toString();
    }

    public static string Dir1
    {
        return MyBaseDir + ConfigurationManager.AppSettings["Dir1"].toString();
    }

}

Usually, I also do type conversions when required in this class. It allows to have a typed access to your config, and if settings change, you can edit them in only one place.

Usually, replacing settings with this class is relatively easy and provides a much greater maintainability.

If you have directory listing disabled in your webserver, then the only way somebody will find it is by guessing or by finding a link to it.

That said, I've seen hacking scripts attempt to "guess" a whole bunch of these common names. "secret.html" would probably be in such a guess list.

The more reasonable solution is to restrict access using a username/password via a htaccess file (for apache) or the equivalent setting for whatever webserver you're using.

Try putting your php into an html document:

Note: your file is not saved as index.html but it is saved as index.php or your php wont work!

 //dont inline your style

 <link rel="stylesheet" type="text/css" href="mystyle.css"> //<--this is the proper way!

 //save a separate style sheet (i.e. cascading style sheet aka: css)

Simply put:

SELECT * 
FROM TABLE_NAME
WHERE
dob > '1/21/2012'

Where 1/21/2012 is the date and you want all data, including that date.

SELECT * 
FROM TABLE_NAME
WHERE
dob BETWEEN '1/21/2012' AND '2/22/2012'

Use a between if you're selecting time between two dates

Put 0 as default in SQL or add 0 into your area of table

This is how I configure it on my server:

0  19  *  *  1,3,5 root bash /home/divo/data/support_files/support_files_inc_backup.sh

The above command will run my script at 19:00 on Monday, Wednesday, and Friday.

NB: For cron entries for day of the week (dow)

0 = Sunday
1 = Monday
2 = Tuesday
3 = Wednesday
4 = Thursday
5 = Friday
6 = Saturday

If you just need a good date-parsing function, I would look at date.js. It will take just about any date string you can throw at it, and return you a JavaScript Date object.

Once you have a Date object, you can call its getTime() method, which will give you milliseconds since January 1, 1970. Just divide that result by 1000 to get the unix timestamp value.

In code, just include date.js, then:

var unixtime = Date.parse("24-Nov-2009 17:57:35").getTime()/1000

One way I would do this without javascript would be to add a set of radio buttons that define the action to be taken:

• Update
• Delete
• Whatever

Then the action script would take different actions depending on the value of the radio button set.

Another way would be to put two forms on the page as you suggested, just not nested. The layout may be difficult to control though:

<form name="editform" action="the_action_url"  method="post">
   <input type="hidden" name="task" value="update" />
   <input type="text" name="foo" />
   <input type="submit" name="save" value="Save" />
</form>

<form name="delform" action="the_action_url"  method="post">
   <input type="hidden" name="task" value="delete" />
   <input type="hidden" name="post_id" value="5" />
   <input type="submit" name="delete" value="Delete" />
</form>

Using the hidden "task" field in the handling script to branch appropriately.

Solutions above didn't work. It simply displayed the last key/value pairs, but this did:

http://localhost/?key[]=1&key[]=2

Returns:

Array
(
[key] => Array
    (
        [0] => 1
        [1] => 2
    )

<div class="widget" ng-controller="widgetController">
    <p>Stuff here</p>
</div>

<div class="menu" ng-controller="menuController">
    <p>Other stuff here</p>
</div>
///////////////// OR ////////////


  <div class="widget" ng-controller="widgetController">
    <p>Stuff here</p>
    <div class="menu" ng-controller="menuController">
        <p>Other stuff here</p>
    </div>
</div>

menuController have access for menu div. And widgetController have access to both.

How about CAST(2229.999 AS DECIMAL(6,2)) to get a decimal with 2 decimal places

Instead of creating a thread, and using runOnUIThread, this is a perfect job for ASyncTask:

• In onPreExecute, create & show the dialog.

• in doInBackground prepare the data, but don't touch the UI -- store each prepared datum in a field, then call publishProgress.

• In onProgressUpdate read the datum field & make the appropriate change/addition to the UI.

• In onPostExecute dismiss the dialog.

If you have other reasons to want a thread, or are adding UI-touching logic to an existing thread, then do a similar technique to what I describe, to run on UI thread only for brief periods, using runOnUIThread for each UI step. In this case, you will store each datum in a local final variable (or in a field of your class), and then use it within a runOnUIThread block.

Use stringi package and stri_length function

> stri_length(c("ala ma kota","ABC",NA))
[1] 11  3 NA

Why? Because it is the FASTEST among presented solutions :)

require(microbenchmark)
require(stringi)
require(stringr)
x <- c(letters,NA,paste(sample(letters,2000,TRUE),collapse=" "))
microbenchmark(nchar(x),str_length(x),stri_length(x))
Unit: microseconds
           expr    min     lq  median      uq     max neval
       nchar(x) 11.868 12.776 13.1590 13.6475  41.815   100
  str_length(x) 30.715 33.159 33.6825 34.1360 173.400   100
 stri_length(x)  2.653  3.281  4.0495  4.5380  19.966   100

and also works fine with NA's

nchar(NA)
## [1] 2
stri_length(NA)
## [1] NA

To clarify a point in Thomas' excellent answer, it should be mentioned that append() is thread safe.

This is because there is no concern that data being read will be in the same place once we go to write to it. The append() operation does not read data, it only writes data to the list.

Here is another way that gives you access to the key and the value at the same time, in case you have to do some kind of transformation.

Map<String, Integer> pointsByName = new HashMap<>();
Map<String, Integer> maxPointsByName = new HashMap<>();

Map<String, Double> gradesByName = pointsByName.entrySet().stream()
        .map(entry -> new AbstractMap.SimpleImmutableEntry<>(
                entry.getKey(), ((double) entry.getValue() /
                        maxPointsByName.get(entry.getKey())) * 100d))
        .collect(Collectors.toMap(Map.Entry::getKey, Map.Entry::getValue));

Also remember to check permission of root directory itself!

You may find:

drwxr-xr-x  9 not-you www-data  4096 Aug  8 16:36 ./
-rw-r--r--  1     you www-data  3012 Aug  8 16:36 README.txt
-rw-r--r--  1     you www-data  3012 Aug  8 16:36 UPDATE.txt

and 'permission denied' error will pop up.

You can add "_CRT_SECURE_NO_WARNINGS" in Preprocessor Definitions.

Right-click your project->Properties->Configuration Properties->C/C++ ->Preprocessor->Preprocessor Definitions.

This project has been tested with Xcode 10 and Swift 4.2.

Create a new project

It can be just a Single View App.

Add the code

Create a new Cocoa Touch Class file (File > New > File... > iOS > Cocoa Touch Class). Name it MyCollectionViewCell. This class will hold the outlets for the views that you add to your cell in the storyboard.

import UIKit
class MyCollectionViewCell: UICollectionViewCell {
    
    @IBOutlet weak var myLabel: UILabel!
}

We will connect this outlet later.

Open ViewController.swift and make sure you have the following content:

import UIKit
class ViewController: UIViewController, UICollectionViewDataSource, UICollectionViewDelegate {
    
    let reuseIdentifier = "cell" // also enter this string as the cell identifier in the storyboard
    var items = ["1", "2", "3", "4", "5", "6", "7", "8", "9", "10", "11", "12", "13", "14", "15", "16", "17", "18", "19", "20", "21", "22", "23", "24", "25", "26", "27", "28", "29", "30", "31", "32", "33", "34", "35", "36", "37", "38", "39", "40", "41", "42", "43", "44", "45", "46", "47", "48"]
    
    
    // MARK: - UICollectionViewDataSource protocol
    
    // tell the collection view how many cells to make
    func collectionView(_ collectionView: UICollectionView, numberOfItemsInSection section: Int) -> Int {
        return self.items.count
    }
    
    // make a cell for each cell index path
    func collectionView(_ collectionView: UICollectionView, cellForItemAt indexPath: IndexPath) -> UICollectionViewCell {
        
        // get a reference to our storyboard cell
        let cell = collectionView.dequeueReusableCell(withReuseIdentifier: reuseIdentifier, for: indexPath as IndexPath) as! MyCollectionViewCell
        
        // Use the outlet in our custom class to get a reference to the UILabel in the cell
        cell.myLabel.text = self.items[indexPath.row] // The row value is the same as the index of the desired text within the array.
        cell.backgroundColor = UIColor.cyan // make cell more visible in our example project
        
        return cell
    }
    
    // MARK: - UICollectionViewDelegate protocol
    
    func collectionView(_ collectionView: UICollectionView, didSelectItemAt indexPath: IndexPath) {
        // handle tap events
        print("You selected cell #\(indexPath.item)!")
    }
}

Notes

• UICollectionViewDataSource and UICollectionViewDelegate are the protocols that the collection view follows. You could also add the UICollectionViewFlowLayout protocol to change the size of the views programmatically, but it isn't necessary.
• We are just putting simple strings in our grid, but you could certainly do images later.

Set up the storyboard

Drag a Collection View to the View Controller in your storyboard. You can add constraints to make it fill the parent view if you like.

Make sure that your defaults in the Attribute Inspector are also

• Items: 1
• Layout: Flow

The little box in the top left of the Collection View is a Collection View Cell. We will use it as our prototype cell. Drag a Label into the cell and center it. You can resize the cell borders and add constraints to center the Label if you like.

Write "cell" (without quotes) in the Identifier box of the Attributes Inspector for the Collection View Cell. Note that this is the same value as let reuseIdentifier = "cell" in ViewController.swift.

And in the Identity Inspector for the cell, set the class name to MyCollectionViewCell, our custom class that we made.

Hook up the outlets

• Hook the Label in the collection cell to myLabel in the MyCollectionViewCell class. (You can Control-drag.)
• Hook the Collection View delegate and dataSource to the View Controller. (Right click Collection View in the Document Outline. Then click and drag the plus arrow up to the View Controller.)

Finished

Here is what it looks like after adding constraints to center the Label in the cell and pinning the Collection View to the walls of the parent.

Making Improvements

The example above works but it is rather ugly. Here are a few things you can play with:

Background color

In the Interface Builder, go to your Collection View > Attributes Inspector > View > Background.

Cell spacing

Changing the minimum spacing between cells to a smaller value makes it look better. In the Interface Builder, go to your Collection View > Size Inspector > Min Spacing and make the values smaller. "For cells" is the horizontal distance and "For lines" is the vertical distance.

Cell shape

If you want rounded corners, a border, and the like, you can play around with the cell layer. Here is some sample code. You would put it directly after cell.backgroundColor = UIColor.cyan in code above.

cell.layer.borderColor = UIColor.black.cgColor
cell.layer.borderWidth = 1
cell.layer.cornerRadius = 8

See this answer for other things you can do with the layer (shadow, for example).

Changing the color when tapped

It makes for a better user experience when the cells respond visually to taps. One way to achieve this is to change the background color while the cell is being touched. To do that, add the following two methods to your ViewController class:

// change background color when user touches cell
func collectionView(_ collectionView: UICollectionView, didHighlightItemAt indexPath: IndexPath) {
    let cell = collectionView.cellForItem(at: indexPath)
    cell?.backgroundColor = UIColor.red
}

// change background color back when user releases touch
func collectionView(_ collectionView: UICollectionView, didUnhighlightItemAt indexPath: IndexPath) {
    let cell = collectionView.cellForItem(at: indexPath)
    cell?.backgroundColor = UIColor.cyan
}

Here is the updated look:

UITableView version of this Q&A

• UITableView example for Swift

This will give you are simple print within a sql script:

select 'This is a comment' AS '';

Alternatively, this will add some dynamic data to your status update if used directly after an update, delete, or insert command:

select concat ("Updated ", row_count(), " rows") as ''; 

In Visual Studio :

//OpenGL
#pragma comment(lib, "opengl32")
#pragma comment(lib, "glu32")
#include <gl/gl.h>
#include <gl/glu.h>

Headers are in the SDK : C:\Program Files\Microsoft SDKs\Windows\v7.0A\Include\gl

It's not a big deal, it's pretty easy to switch between them. MSTest being integrated isn't a big deal either, just grab testdriven.net.

Like the previous person said pick a mocking framework, my favourite at the moment is Moq.

Run these commands for Beyond Compare 3(if the BCompare.exe path is different in your system, please replace it according to yours):

git config --global diff.tool bc3
git config --global difftool.bc3.cmd "\"c:/program files (x86)/beyond compare 3/BCompare.exe\" \"$LOCAL\" \"$REMOTE\""
git config --global difftool.prompt false

Then use git difftool

Here is the code to generate random alphanumeric code. First you have to declare a string of allowed characters what you want to include in random number.and also define max length of string

 SecureRandom secureRandom = new SecureRandom();
 String CHARACTERS = "ABCDEFGHIJKLMNOPQRSTUVWXYZ123456789";
    StringBuilder generatedString= new StringBuilder();
    for (int i = 0; i < MAXIMUM_LENGTH; i++) {
        int randonSequence = secureRandom .nextInt(CHARACTERS.length());
        generatedString.append(CHARACTERS.charAt(randonSequence));
    }

Use toString() method to get String from StringBuilder

I had a similar problem when I had installed the 12c database as per Oracle's tutorial . The instruction instructs reader to create a PLUGGABLE DATABASE (pdb).

The problem

sqlplus hr/hr@pdborcl would result in ORACLE initialization or shutdown in progress.

The solution

• 1. Login as SYSDBA to the dabase :

     sqlplus SYS/Oracle_1@pdborcl AS SYSDBA
     

• 2. Alter database:

     alter pluggable database pdborcl open read write;
     

• 3. Login again:

     sqlplus hr/hr@pdborcl
     

That worked for me

Some documentation here

$("input[required]").attr("oninvalid", "this.setCustomValidity('Say Somthing!')");

this work if you move to previous or next field by mouse, but by enter key, this is not work !!!

I just encountered the same problem and it had to do with some files being lost or corrupted. To correct the issue, just run check disk:

chkdsk /F e:

This can be run from the search windows box or from a cmd prompt. The /F fixes any issues it finds, like recovering the files. Once this finishes running, you can delete the files and folders like normal.

depending on who is going to be using your database, for example African names will do with varchar(20) for last name and first name separated. however it is different from nation to nation but for the sake saving your database resources and memory, separate last name and first name fields and use varchar(30) think that will work.

I just tried the following:

 $ cat gdbtest.c
 int abc = 43;

 int main()
 {
   abc = 10;
 }
 $ gcc -g -o gdbtest gdbtest.c
 $ gdb gdbtest
 ...
 (gdb) watch abc
 Hardware watchpoint 1: abc
 (gdb) r
 Starting program: /home/mweerden/gdbtest 
 ...

 Old value = 43
 New value = 10
 main () at gdbtest.c:6
 6       }
 (gdb) quit

So it seems possible, but you do appear to need some hardware support.

This discuss in great detail about shared libraries on linux and performance implications.

Use the timestamp you get by calling valueOf on the date object:

var diff = date2.valueOf() - date1.valueOf();
var diffInHours = diff/1000/60/60; // Convert milliseconds to hours

Realising this is an old question. I still would like to post this answer, as I had some problems popping several viewControllers with the proposed answers. My solution is to subclass UINavigationController and override all the pop and push methods.

As Matt Ball's answer explains, or is "and/or". But or doesn't work with in the way you use it above. You have to say if "a" in someList or "á" in someList or.... Or better yet,

if any(c in someList for c in ("a", "á", "à", "ã", "â")):
    ...

That's the answer to your question as asked.

Other Notes

However, there are a few more things to say about the example code you've posted. First, the chain of someList.remove... or someList remove... statements here is unnecessary, and may result in unexpected behavior. It's also hard to read! Better to break it into individual lines:

someList.remove("a")
someList.remove("á")
...

Even that's not enough, however. As you observed, if the item isn't in the list, then an error is thrown. On top of that, using remove is very slow, because every time you call it, Python has to look at every item in the list. So if you want to remove 10 different characters, and you have a list that has 100 characters, you have to perform 1000 tests.

Instead, I would suggest a very different approach. Filter the list using a set, like so:

chars_to_remove = set(("a", "á", "à", "ã", "â"))
someList = [c for c in someList if c not in chars_to_remove]

Or, change the list in-place without creating a copy:

someList[:] = (c for c in someList if c not in chars_to_remove)

These both use list comprehension syntax to create a new list. They look at every character in someList, check to see of the character is in chars_to_remove, and if it is not, they include the character in the new list.

This is the most efficient version of this code. It has two speed advantages:

1. It only passes through someList once. Instead of performing 1000 tests, in the above scenario, it performs only 100.
2. It can test all characters with a single operation, because chars_to_remove is a set. If it chars_to_remove were a list or tuple, then each test would really be 10 tests in the above scenario -- because each character in the list would need to be checked individually.

   <Button
        android:id="@+id/button1"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="News Feed"
        android:icon="@drawable/newsfeed" />

newsfeed is image in the drawable folder

RichTextBox will allow you to use html to specify the color. Another alternative is using a listbox and using the DrawItem event to draw how you would like. AFAIK, textbox itself can't be used in the way you're hoping.

If you are sure that your xml is encoded in UTF-8 but contains bad characters, you can use this function to correct them :

$content = iconv('UTF-8', 'UTF-8//IGNORE', $content);

I think you need also to specify the name of the database:

SELECT COUNT(*)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_schema = 'SchemaNameHere'
  AND table_name = 'TableNameHere'

if you don't specify the name of your database, chances are it will count all columns as long as it matches the name of your table. For example, you have two database: DBaseA and DbaseB, In DBaseA, it has two tables: TabA(3 fields), TabB(4 fields). And in DBaseB, it has again two tables: TabA(4 fields), TabC(4 fields).

if you run this query:

SELECT count(*)
FROM information_schema.columns
WHERE table_name = 'TabA'

it will return 7 because there are two tables named TabA. But by adding another condition table_schema = 'SchemaNameHere':

SELECT COUNT(*)
FROM INFORMATION_SCHEMA.COLUMNS
WHERE table_schema = 'DBaseA'
  AND table_name = 'TabA'

then it will only return 3.

If you actually want a static property of your class, that isn't currently supported in Swift. The current advice is to get around that by using global constants:

let testStr = "test"
let testStrLen = countElements(testStr)

class MyClass {
    func myFunc() {
    }
}

If you want these to be instance properties instead, you can use a lazy stored property for the length -- it will only get evaluated the first time it is accessed, so you won't be computing it over and over.

class MyClass {
    let testStr: String = "test"
    lazy var testStrLen: Int = countElements(self.testStr)

    func myFunc() {
    }
}

I will make a little bit wider answer here.

There are generally speaking two types of conditional jumps in x86:

1. Arithmetic jumps - like JZ (jump if zero), JC (jump if carry), JNC (jump if not carry), etc.

2. Comparison jumps - JE (jump if equal), JB (jump if below), JAE (jump if above or equal), etc.

So, use the first type only after arithmetic or logical instructions:

sub  eax, ebx
jnz  .result_is_not_zero 

and  ecx, edx
jz   .the_bit_is_not_set

Use the second group only after CMP instructions:

cmp  eax, ebx
jne  .eax_is_not_equal_to_ebx

cmp  ecx, edx
ja   .ecx_is_above_than_edx

This way, the program becomes more readable and you will never be confused.

Note, that sometimes these instructions are actually synonyms. JZ == JE; JC == JB; JNC == JAE and so on. The full table is following. As you can see, there are only 16 conditional jump instructions, but 30 mnemonics - they are provided to allow creation of more readable source code:

Mnemonic        Condition tested  Description  

jo              OF = 1            overflow 
jno             OF = 0            not overflow 
jc, jb, jnae    CF = 1            carry / below / not above nor equal
jnc, jae, jnb   CF = 0            not carry / above or equal / not below
je, jz          ZF = 1            equal / zero
jne, jnz        ZF = 0            not equal / not zero
jbe, jna        CF or ZF = 1      below or equal / not above
ja, jnbe        CF and ZF = 0      above / not below or equal
js              SF = 1            sign 
jns             SF = 0            not sign 
jp, jpe         PF = 1            parity / parity even 
jnp, jpo        PF = 0            not parity / parity odd 
jl, jnge        SF xor OF = 1     less / not greater nor equal
jge, jnl        SF xor OF = 0     greater or equal / not less
jle, jng    (SF xor OF) or ZF = 1 less or equal / not greater
jg, jnle    (SF xor OF) or ZF = 0 greater / not less nor equal 

You haven't provided your javascript code, but the usual cause of this type of issue is not waiting till the page is loaded. Remember that most javascript is executed before the DOM is loaded, so code trying to manipulate it won't work.

To run code after the page has finished loading, use the $(document).ready callback:

$(document).ready(function(){
  $('#some-id').trigger('click');
});

Things like these are why I switched to Powershell. Try it out, it's fun:

Get-ChildItem -Recurse -Include *.doc | % {
    Copy-Item $_.FullName -destination x:\destination
}

redirect_to :controller => "controller_name", :action => "action_name", :id => x.id

Here's a method I wrote for a "run all JUnits under a package". You should be able to adapt it to your needs.

private static void findClassesInJar(List<String> classFiles, String path) throws IOException {
    final String[] parts = path.split("\\Q.jar\\\\E");
    if (parts.length == 2) {
        String jarFilename = parts[0] + ".jar";
        String relativePath = parts[1].replace(File.separatorChar, '/');
        JarFile jarFile = new JarFile(jarFilename);
        final Enumeration<JarEntry> entries = jarFile.entries();
        while (entries.hasMoreElements()) {
            final JarEntry entry = entries.nextElement();
            final String entryName = entry.getName();
            if (entryName.startsWith(relativePath)) {
                classFiles.add(entryName.replace('/', File.separatorChar));
            }
        }
    }
}

Edit: Ah, in that case, you might want this snippet as well (same use case :) )

private static File findClassesDir(Class<?> clazz) {
    try {
        String path = clazz.getProtectionDomain().getCodeSource().getLocation().getFile();
        final String codeSourcePath = URLDecoder.decode(path, "UTF-8");
        final String thisClassPath = new File(codeSourcePath, clazz.getPackage().getName().repalce('.', File.separatorChar));
    } catch (UnsupportedEncodingException e) {
        throw new AssertionError("impossible", e);
    }
}

Building on Chad's answer, you also want to add that function to the onload event to ensure it is resized when the page loads as well.

jQuery.event.add(window, "load", resizeFrame);
jQuery.event.add(window, "resize", resizeFrame);

function resizeFrame() 
{
    var h = $(window).height();
    var w = $(window).width();
    $("#elementToResize").css('height',(h < 768 || w < 1024) ? 500 : 400);
}

Nevermind found an answer. Ty the same for anyone who was willing to reply.

WHERE DATEDIFF(mydata,'2008-11-20') >=0;

I break the task up into smaller units. Test with different batch size intervals for your table, until you find an interval that performs optimally. Here is a sample that I have used in the past.

declare @counter int 
declare @numOfRecords int
declare @batchsize int

set @numOfRecords = (SELECT COUNT(*) AS NumberOfRecords FROM <TABLE> with(nolock))
set @counter = 0 
set @batchsize = 2500

set rowcount @batchsize
while @counter < (@numOfRecords/@batchsize) +1
begin 
set @counter = @counter + 1 
Update table set int_field = -1 where int_field <> -1;
end 
set rowcount 0

Here a CSS animation fork of jezzipin's Solution, to seperate code from styling.

JS:

$(window).on("scroll touchmove", function () {
  $('#header_nav').toggleClass('tiny', $(document).scrollTop() > 0);
});

CSS:

.header {
  width:100%;
  height:100px;
  background: #26b;
  color: #fff;
  position:fixed;
  top:0;
  left:0;
  transition: height 500ms, background 500ms;
}
.header.tiny {
  height:40px;
  background: #aaa;
}

http://jsfiddle.net/sinky/S8Fnq/

On scroll/touchmove the css class "tiny" is set to "#header_nav" if "$(document).scrollTop()" is greater than 0.

CSS transition attribute animates the "height" and "background" attribute nicely.

Copies a directory named html & all its contents to a destination directory in silent mode. If the destination directory is not present it will still create it.

@echo off
TITLE Copy Folder with Contents

set SOURCE=C:\labs
set DESTINATION=C:\Users\MyUser\Desktop\html

xcopy %SOURCE%\html\* %DESTINATION%\* /s /e /i /Y >NUL

1. /S Copies directories and subdirectories except empty ones.

2. /E Copies directories and subdirectories, including empty ones. Same as /S /E. May be used to modify /T.

3. /I If destination does not exist and copying more than one file, assumes that destination must be a directory.

4. /Y Suppresses prompting to confirm you want to overwrite an existing destination file.

If loading images dynamically one can create a .js file like following and do require in it.

export const data = [
  {
    id: "1",
    text: "blablabla1",
    imageLink: require('../assets/first-image.png')
  },
  {
    id: "2",
    text: "blablabla2",
    imageLink: require('../assets/second-image.png')
  }
]

In your component .js file

import {data} from './js-u-created-above';
...

function UsageExample({item}) {
   <View>
     <Image style={...} source={item.imageLink} /> 
   </View>
}

function ComponentName() {
   const elements = data.map(item => <UsageExample key={item.id} item={item}/> );
   return (...);
}

Checkout the following article on MSDN about examples of the N format. This is also covered in the Standard Numeric Format Strings article.

Relevant excerpts:

//       Formatting of 1054.32179:
//          N:                     1,054.32 
//          N0:                    1,054 
//          N1:                    1,054.3 
//          N2:                    1,054.32 
//          N3:                    1,054.322 

When precision specifier controls the number of fractional digits in the result string, the result string reflects a number that is rounded to a representable result nearest to the infinitely precise result. If there are two equally near representable results:

• On the .NET Framework and .NET Core up to .NET Core 2.0, the runtime selects the result with the greater least significant digit (that is, using MidpointRounding.AwayFromZero).
• On .NET Core 2.1 and later, the runtime selects the result with an even least significant digit (that is, using MidpointRounding.ToEven).

From the WooCommerce page:

// WooCommerce – display category image on category archive

add_action( 'woocommerce_archive_description', 'woocommerce_category_image', 2 );
function woocommerce_category_image() {
    if ( is_product_category() ){
      global $wp_query;
      $cat = $wp_query->get_queried_object();
      $thumbnail_id = get_woocommerce_term_meta( $cat->term_id, 'thumbnail_id', true );
      $image = wp_get_attachment_url( $thumbnail_id );
      if ( $image ) {
          echo '<img src="' . $image . '" alt="" />';
      }
  }
}

This seems to work.

You need to add a <meta> tag in your <head> containing name="theme-color", with your HEX code as the content value. For example:

<meta name="theme-color" content="#999999" />

Update:

If the android device has native dark-mode enabled, then this meta tag is ignored.

Chrome for Android does not use the color on devices with native dark-mode enabled.

Some of the other answers here inspired me to write a script for automating the mixed sequential execution of SQL tasks using SQLPLUS along with shell commands for a project, a process that was previously manually done. Maybe this (highly sanitized) example will be useful to someone else:

#!/bin/bash
acreds="user_a/supergreatpassword"
bcreds="user_b/anothergreatpassword"
hoststring='fancyoraclehoststring'

runsql () {
  # param 1 is $1
sqlplus -S /nolog << EOF
CONNECT $1@$hoststring;
whenever sqlerror exit sql.sqlcode;
set echo off
set heading off
$2
exit;
EOF
}

echo "TS::$(date): Starting SCHEM_A.PROC_YOU_NEED()..."
runsql "$acreds" "execute SCHEM_A.PROC_YOU_NEED();"

echo "TS::$(date): Starting superusefuljob..."
/var/scripts/superusefuljob.sh

echo "TS::$(date): Starting SCHEM_B.SECRET_B_PROC()..."
runsql "$bcreds" "execute SCHEM_B.SECRET_B_PROC();"

echo "TS::$(date): DONE"

runsql allows you to pass a credential string as the first argument, and any SQL you need as the second argument. The variables containing the credentials are included for illustration, but for security I actually source them from another file. If you wanted to handle multiple database connections, you could easily modify the function to accept the hoststring as an additional parameter.

What you should know about this

this (aka "the context") is a special keyword inside each function and its value only depends on how the function was called, not how/when/where it was defined. It is not affected by lexical scopes like other variables (except for arrow functions, see below). Here are some examples:

function foo() {
    console.log(this);
}

// normal function call
foo(); // `this` will refer to `window`

// as object method
var obj = {bar: foo};
obj.bar(); // `this` will refer to `obj`

// as constructor function
new foo(); // `this` will refer to an object that inherits from `foo.prototype`

To learn more about this, have a look at the MDN documentation.

How to refer to the correct this

Use arrow functions

ECMAScript 6 introduced arrow functions, which can be thought of as lambda functions. They don't have their own this binding. Instead, this is looked up in scope just like a normal variable. That means you don't have to call .bind. That's not the only special behavior they have, please refer to the MDN documentation for more information.

function MyConstructor(data, transport) {
    this.data = data;
    transport.on('data', () => alert(this.data));
}

Don't use this

You actually don't want to access this in particular, but the object it refers to. That's why an easy solution is to simply create a new variable that also refers to that object. The variable can have any name, but common ones are self and that.

function MyConstructor(data, transport) {
    this.data = data;
    var self = this;
    transport.on('data', function() {
        alert(self.data);
    });
}

Since self is a normal variable, it obeys lexical scope rules and is accessible inside the callback. This also has the advantage that you can access the this value of the callback itself.

Explicitly set this of the callback - part 1

It might look like you have no control over the value of this because its value is set automatically, but that is actually not the case.

Every function has the method .bind ^[docs], which returns a new function with this bound to a value. The function has exactly the same behavior as the one you called .bind on, only that this was set by you. No matter how or when that function is called, this will always refer to the passed value.

function MyConstructor(data, transport) {
    this.data = data;
    var boundFunction = (function() { // parenthesis are not necessary
        alert(this.data);             // but might improve readability
    }).bind(this); // <- here we are calling `.bind()` 
    transport.on('data', boundFunction);
}

In this case, we are binding the callback's this to the value of MyConstructor's this.

Note: When a binding context for jQuery, use jQuery.proxy ^[docs] instead. The reason to do this is so that you don't need to store the reference to the function when unbinding an event callback. jQuery handles that internally.

Set this of the callback - part 2

Some functions/methods which accept callbacks also accept a value to which the callback's this should refer to. This is basically the same as binding it yourself, but the function/method does it for you. Array#map ^[docs] is such a method. Its signature is:

array.map(callback[, thisArg])

The first argument is the callback and the second argument is the value this should refer to. Here is a contrived example:

var arr = [1, 2, 3];
var obj = {multiplier: 42};

var new_arr = arr.map(function(v) {
    return v * this.multiplier;
}, obj); // <- here we are passing `obj` as second argument

Note: Whether or not you can pass a value for this is usually mentioned in the documentation of that function/method. For example, jQuery's $.ajax method ^[docs] describes an option called context:

This object will be made the context of all Ajax-related callbacks.

Common problem: Using object methods as callbacks/event handlers

Another common manifestation of this problem is when an object method is used as callback/event handler. Functions are first-class citizens in JavaScript and the term "method" is just a colloquial term for a function that is a value of an object property. But that function doesn't have a specific link to its "containing" object.

Consider the following example:

function Foo() {
    this.data = 42,
    document.body.onclick = this.method;
}

Foo.prototype.method = function() {
    console.log(this.data);
};

The function this.method is assigned as click event handler, but if the document.body is clicked, the value logged will be undefined, because inside the event handler, this refers to the document.body, not the instance of Foo.
As already mentioned at the beginning, what this refers to depends on how the function is called, not how it is defined.
If the code was like the following, it might be more obvious that the function doesn't have an implicit reference to the object:

function method() {
    console.log(this.data);
}


function Foo() {
    this.data = 42,
    document.body.onclick = this.method;
}

Foo.prototype.method = method;

The solution is the same as mentioned above: If available, use .bind to explicitly bind this to a specific value

document.body.onclick = this.method.bind(this);

or explicitly call the function as a "method" of the object, by using an anonymous function as callback / event handler and assign the object (this) to another variable:

var self = this;
document.body.onclick = function() {
    self.method();
};

or use an arrow function:

document.body.onclick = () => this.method();

Upcasting (using (Employee)someInstance) is generally easy as the compiler can tell you at compile time if a type is derived from another.

Downcasting however has to be done at run time generally as the compiler may not always know whether the instance in question is of the type given. C# provides two operators for this - is which tells you if the downcast works, and return true/false. And as which attempts to do the cast and returns the correct type if possible, or null if not.

To test if an employee is a manager:

Employee m = new Manager();
Employee e = new Employee();

if(m is Manager) Console.WriteLine("m is a manager");
if(e is Manager) Console.WriteLine("e is a manager");

You can also use this

Employee someEmployee = e  as Manager;
    if(someEmployee  != null) Console.WriteLine("someEmployee (e) is a manager");

Employee someEmployee = m  as Manager;
    if(someEmployee  != null) Console.WriteLine("someEmployee (m) is a manager");

I don't like absolute positioning, either, because there is almost always some collateral damage, i.e. unintended side effects. Especially when you are working with a responsive design. There seems to be an alternative - the sandbag technique. By inserting a "helper" element, either in the markup of via CSS, we can push elements down to the bottom of the container. See http://community.sitepoint.com/t/css-floating-divs-to-the-bottom-inside-a-div/20932 for examples.

The Chromatable jquery plugin allows a fixed header (or top row) with widths that allow percentages--granted, only a percentage of 100%.

http://www.chromaloop.com/posts/chromatable-jquery-plugin

I can't think of how you could do this without javascript.

On Yosemite, install vim using brew and the override-system-vi option. This will automatically install vim with the features of the 'huge' vim install.

brew install vim --with-override-system-vi

The output of this command will show you where brew installed vim. In that folder, go down into /bin/vim to actually run vim. This is your command to run vim from any folder:

/usr/local/Cellar/vim/7.4.873/bin/vim

Then alias this command by adding the following line in your .bashrc:

alias vim="/usr/local/Cellar/vim/7.4.873/bin/vim"

EDIT: Brew flag --override-system-vi has been deprecated. Changed for --with-override-system-vi. Source: https://github.com/Shougo/neocomplete.vim/issues/401

With the help of user=User.query.filter_by(username=form.username.data).first() statement you will get the specified user in user variable.

Now you can change the value of the new object variable like user.no_of_logins += 1 and save the changes with the session's commit method.

If you're not sure your input is going to be a Numpy array, you can use asarray with dtype=int instead of astype:

>>> np.asarray([1,2,3,4], dtype=int)
array([1, 2, 3, 4])

If the input array already has the correct dtype, asarray avoids the array copy while astype does not (unless you specify copy=False):

>>> a = np.array([1,2,3,4])
>>> a is np.asarray(a)  # no copy :)
True
>>> a is a.astype(int)  # copy :(
False
>>> a is a.astype(int, copy=False)  # no copy :)
True

Most jquery code executes on document ready, which doesn't happen until the end of the page anyway. Furthermore, page rendering can be delayed by javascript parsing/execution, so it's best practice to put all javascript at the bottom of the page.

If push request is shows Rejected, then try first pull from your github account and then try push.

App Store Connect

1. Go to appstoreconnect.apple.com and log in
2. Click My Apps then click the app you want do add the purchase to
3. Click the Features header, and then select In-App Purchases on the left
4. Click the + icon in the middle
5. For this tutorial, we are going to be adding an in-app purchase to remove ads, so choose non-consumable. If you were going to send a physical item to the user, or give them something that they can buy more than once, you would choose consumable.
6. For the reference name, put whatever you want (but make sure you know what it is)
7. For product id put tld.websitename.appname.referencename this will work the best, so for example, you could use com.jojodmo.blix.removeads
8. Choose cleared for sale and then choose price tier as 1 (99¢). Tier 2 would be $1.99, and tier 3 would be $2.99. The full list is available if you click view pricing matrix I recommend you use tier 1, because that's usually the most anyone will ever pay to remove ads.
9. Click the blue add language button, and input the information. This will ALL be shown to the customer, so don't put anything you don't want them seeing
10. For hosting content with Apple choose no
11. You can leave the review notes blank FOR NOW.
12. Skip the screenshot for review FOR NOW, everything we skip we will come back to.
13. Click 'save'

It could take a few hours for your product ID to register in App Store Connect, so be patient.

Setting up your project

Now that you've set up your in-app purchase information on App Store Connect, go into your Xcode project, and go to the application manager (blue page-like icon at the top of where your methods and header files are) click on your app under targets (should be the first one) then go to general. At the bottom, you should see linked frameworks and libraries click the little plus symbol and add the framework StoreKit.framework If you don't do this, the in-app purchase will NOT work!

If you are using Objective-C as the language for your app, you should skip these five steps. Otherwise, if you are using Swift, you can follow My Swift Answer for this question, here, or, if you prefer to use Objective-C for the In-App Purchase code but are using Swift in your app, you can do the following:

1. Create a new .h (header) file by going to File > New > File... (Command ? + N). This file will be referred to as "Your .h file" in the rest of the tutorial

2. When prompted, click Create Bridging Header. This will be our bridging header file. If you are not prompted, go to step 3. If you are prompted, skip step 3 and go directly to step 4.

3. Create another .h file named Bridge.h in the main project folder, Then go to the Application Manager (the blue page-like icon), then select your app in the Targets section, and click Build Settings. Find the option that says Swift Compiler - Code Generation, and then set the Objective-C Bridging Header option to Bridge.h

4. In your bridging header file, add the line #import "MyObjectiveCHeaderFile.h", where MyObjectiveCHeaderFile is the name of the header file that you created in step one. So, for example, if you named your header file InAppPurchase.h, you would add the line #import "InAppPurchase.h" to your bridge header file.

5. Create a new Objective-C Methods (.m) file by going to File > New > File... (Command ? + N). Name it the same as the header file you created in step 1. For example, if you called the file in step 1 InAppPurchase.h, you would call this new file InAppPurchase.m. This file will be referred to as "Your .m file" in the rest of the tutorial.

Coding

Now we're going to get into the actual coding. Add the following code into your .h file:

BOOL areAdsRemoved;

- (IBAction)restore;
- (IBAction)tapsRemoveAds;

Next, you need to import the StoreKit framework into your .m file, as well as add SKProductsRequestDelegate and SKPaymentTransactionObserver after your @interface declaration:

#import <StoreKit/StoreKit.h>

//put the name of your view controller in place of MyViewController
@interface MyViewController() <SKProductsRequestDelegate, SKPaymentTransactionObserver>

@end

@implementation MyViewController //the name of your view controller (same as above)
  //the code below will be added here
@end

and now add the following into your .m file, this part gets complicated, so I suggest that you read the comments in the code:

//If you have more than one in-app purchase, you can define both of
//of them here. So, for example, you could define both kRemoveAdsProductIdentifier
//and kBuyCurrencyProductIdentifier with their respective product ids
//
//for this example, we will only use one product

#define kRemoveAdsProductIdentifier @"put your product id (the one that we just made in App Store Connect) in here"

- (IBAction)tapsRemoveAds{
    NSLog(@"User requests to remove ads");

    if([SKPaymentQueue canMakePayments]){
        NSLog(@"User can make payments");
    
        //If you have more than one in-app purchase, and would like
        //to have the user purchase a different product, simply define 
        //another function and replace kRemoveAdsProductIdentifier with 
        //the identifier for the other product

        SKProductsRequest *productsRequest = [[SKProductsRequest alloc] initWithProductIdentifiers:[NSSet setWithObject:kRemoveAdsProductIdentifier]];
        productsRequest.delegate = self;
        [productsRequest start];
    
    }
    else{
        NSLog(@"User cannot make payments due to parental controls");
        //this is called the user cannot make payments, most likely due to parental controls
    }
}

- (void)productsRequest:(SKProductsRequest *)request didReceiveResponse:(SKProductsResponse *)response{
    SKProduct *validProduct = nil;
    int count = [response.products count];
    if(count > 0){
        validProduct = [response.products objectAtIndex:0];
        NSLog(@"Products Available!");
        [self purchase:validProduct];
    }
    else if(!validProduct){
        NSLog(@"No products available");
        //this is called if your product id is not valid, this shouldn't be called unless that happens.
    }
}

- (void)purchase:(SKProduct *)product{
    SKPayment *payment = [SKPayment paymentWithProduct:product];

    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] addPayment:payment];
}

- (IBAction) restore{
    //this is called when the user restores purchases, you should hook this up to a button
    [[SKPaymentQueue defaultQueue] addTransactionObserver:self];
    [[SKPaymentQueue defaultQueue] restoreCompletedTransactions];
}

- (void) paymentQueueRestoreCompletedTransactionsFinished:(SKPaymentQueue *)queue
{
    NSLog(@"received restored transactions: %i", queue.transactions.count);
    for(SKPaymentTransaction *transaction in queue.transactions){
        if(transaction.transactionState == SKPaymentTransactionStateRestored){
            //called when the user successfully restores a purchase
            NSLog(@"Transaction state -> Restored");

            //if you have more than one in-app purchase product,
            //you restore the correct product for the identifier.
            //For example, you could use
            //if(productID == kRemoveAdsProductIdentifier)
            //to get the product identifier for the
            //restored purchases, you can use
            //
            //NSString *productID = transaction.payment.productIdentifier;
            [self doRemoveAds];
            [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
            break;
        }
    }   
}

- (void)paymentQueue:(SKPaymentQueue *)queue updatedTransactions:(NSArray *)transactions{
    for(SKPaymentTransaction *transaction in transactions){
        //if you have multiple in app purchases in your app,
        //you can get the product identifier of this transaction
        //by using transaction.payment.productIdentifier
        //
        //then, check the identifier against the product IDs
        //that you have defined to check which product the user
        //just purchased            

        switch(transaction.transactionState){
            case SKPaymentTransactionStatePurchasing: NSLog(@"Transaction state -> Purchasing");
                //called when the user is in the process of purchasing, do not add any of your own code here.
                break;
            case SKPaymentTransactionStatePurchased:
            //this is called when the user has successfully purchased the package (Cha-Ching!)
                [self doRemoveAds]; //you can add your code for what you want to happen when the user buys the purchase here, for this tutorial we use removing ads
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                NSLog(@"Transaction state -> Purchased");
                break;
            case SKPaymentTransactionStateRestored:
                NSLog(@"Transaction state -> Restored");
                //add the same code as you did from SKPaymentTransactionStatePurchased here
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
            case SKPaymentTransactionStateFailed:
                //called when the transaction does not finish
                if(transaction.error.code == SKErrorPaymentCancelled){
                    NSLog(@"Transaction state -> Cancelled");
                    //the user cancelled the payment ;(
                }
                [[SKPaymentQueue defaultQueue] finishTransaction:transaction];
                break;
        }
    }
}

Now you want to add your code for what will happen when the user finishes the transaction, for this tutorial, we use removing adds, you will have to add your own code for what happens when the banner view loads.

- (void)doRemoveAds{
    ADBannerView *banner;
    [banner setAlpha:0];
    areAdsRemoved = YES;
    removeAdsButton.hidden = YES;
    removeAdsButton.enabled = NO;
    [[NSUserDefaults standardUserDefaults] setBool:areAdsRemoved forKey:@"areAdsRemoved"];
    //use NSUserDefaults so that you can load whether or not they bought it
    //it would be better to use KeyChain access, or something more secure
    //to store the user data, because NSUserDefaults can be changed.
    //You're average downloader won't be able to change it very easily, but
    //it's still best to use something more secure than NSUserDefaults.
    //For the purpose of this tutorial, though, we're going to use NSUserDefaults
    [[NSUserDefaults standardUserDefaults] synchronize];
}

If you don't have ads in your application, you can use any other thing that you want. For example, we could make the color of the background blue. To do this we would want to use:

- (void)doRemoveAds{
    [self.view setBackgroundColor:[UIColor blueColor]];
    areAdsRemoved = YES
    //set the bool for whether or not they purchased it to YES, you could use your own boolean here, but you would have to declare it in your .h file

    [[NSUserDefaults standardUserDefaults] setBool:areAdsRemoved forKey:@"areAdsRemoved"];
    //use NSUserDefaults so that you can load wether or not they bought it
    [[NSUserDefaults standardUserDefaults] synchronize];
}

Now, somewhere in your viewDidLoad method, you're going to want to add the following code:

areAdsRemoved = [[NSUserDefaults standardUserDefaults] boolForKey:@"areAdsRemoved"];
[[NSUserDefaults standardUserDefaults] synchronize];
//this will load wether or not they bought the in-app purchase

if(areAdsRemoved){
    [self.view setBackgroundColor:[UIColor blueColor]];
    //if they did buy it, set the background to blue, if your using the code above to set the background to blue, if your removing ads, your going to have to make your own code here
}

Now that you have added all the code, go into your .xib or storyboard file, and add two buttons, one saying purchase, and the other saying restore. Hook up the tapsRemoveAds IBAction to the purchase button that you just made, and the restore IBAction to the restore button. The restore action will check if the user has previously purchased the in-app purchase, and give them the in-app purchase for free if they do not already have it.

Submitting for review

Next, go into App Store Connect, and click Users and Access then click the Sandbox Testers header, and then click the + symbol on the left where it says Testers. You can just put in random things for the first and last name, and the e-mail does not have to be real - you just have to be able to remember it. Put in a password (which you will have to remember) and fill in the rest of the info. I would recommend that you make the Date of Birth a date that would make the user 18 or older. App Store Territory HAS to be in the correct country. Next, log out of your existing iTunes account (you can log back in after this tutorial).

Now, run your application on your iOS device, if you try running it on the simulator, the purchase will always error, you HAVE TO run it on your iOS device. Once the app is running, tap the purchase button. When you are prompted to log into your iTunes account, log in as the test user that we just created. Next,when it asks you to confirm the purchase of 99¢ or whatever you set the price tier too, TAKE A SCREEN SNAPSHOT OF IT this is what your going to use for your screenshot for review on App Store Connect. Now cancel the payment.

Now, go to App Store Connect, then go to My Apps > the app you have the In-app purchase on > In-App Purchases. Then click your in-app purchase and click edit under the in-app purchase details. Once you've done that, import the photo that you just took on your iPhone into your computer, and upload that as the screenshot for review, then, in review notes, put your TEST USER e-mail and password. This will help apple in the review process.

After you have done this, go back onto the application on your iOS device, still logged in as the test user account, and click the purchase button. This time, confirm the payment Don't worry, this will NOT charge your account ANY money, test user accounts get all in-app purchases for free After you have confirmed the payment, make sure that what happens when the user buys your product actually happens. If it doesn't, then thats going to be an error with your doRemoveAds method. Again, I recommend using changing the background to blue for testing the in-app purchase, this should not be your actual in-app purchase though. If everything works and you're good to go! Just make sure to include the in-app purchase in your new binary when you upload it to App Store Connect!

Here are some common errors:

Logged: No Products Available

This could mean four things:

• You didn't put the correct in-app purchase ID in your code (for the identifier kRemoveAdsProductIdentifier in the above code
• You didn't clear your in-app purchase for sale on App Store Connect
• You didn't wait for the in-app purchase ID to be registered in App Store Connect. Wait a couple hours from creating the ID, and your problem should be resolved.
• You didn't complete filling your Agreements, Tax, and Banking info.

If it doesn't work the first time, don't get frustrated! Don't give up! It took me about 5 hours straight before I could get this working, and about 10 hours searching for the right code! If you use the code above exactly, it should work fine. Feel free to comment if you have any questions at all.

I hope this helps to all of those hoping to add an in-app purchase to their iOS application. Cheers!

Press the F12 function key in the Chrome browser to launch the JavaScript debugger and then click "Scripts".

Choose the JavaScript file on top and place the breakpoint to the debugger for the JavaScript code.

SQL Server 2012 introduced IIF:

SELECT 
    o.OrderId, 
    IIF( ISNULL( o.NegotiatedPrice, 0 ) > ISNULL( o.SuggestedPrice, 0 ),
         o.NegotiatedPrice, 
         o.SuggestedPrice 
    )
FROM 
    Order o

Handling NULLs is recommended when using IIF, because a NULL on either side of your boolean_expression will cause IIF to return the false_value (as opposed to NULL).

If one want to make executable hello.py

first find the path where python is in your os with : which python

it usually resides under "/usr/bin/python" folder.

at the very first line of hello.py one should add : #!/usr/bin/python

then through linux command chmod

one should just make it executable like : chmod +x hello.py

and execute with ./hello.py

What most people forget it is that the files of visual studio are just text files, that have some peculiars configurations that will show to the program how to open it. that is, we can change this because it's just a text in some file in there in your project folders.

Well, knowing this, what we have to do is very simple!

The first step is knowing what kind of project it is this project that stay unload. (for example: Class Library)

The Second step is create a new one (Class Library) because you know that your visual studio will create a version supported by himself. Unload this one and click in "Edit csproj".

It's in this file that we can found the configuration that tell to VS how this proj will be loaded and his name is ProjectGuid, this serial number has a variation according the type and version of project.

Now, look at your "ok project", copy the "ProjectGuid" TAG, paste on csproj that unloaded, and pay attention to the little differences and make this files almost equals, except for the tags ItemGroup that represent the references of the project.

Doing that, save all files and close your VS and open again, now your project should load normally.

I hope that this informations help somebody to understand a bit more how the VS works and help solve the problems when necessary.

You are trying to remove value from list in advanced "for loop", which is not possible, even if you apply any trick (which you did in your code). Better way is to code iterator level as other advised here.

I wonder how people have not suggested traditional for loop approach.

for( int i = 0; i < lStringList.size(); i++ )
{
    String lValue = lStringList.get( i );
    if(lValue.equals("_Not_Required"))
    {
         lStringList.remove(lValue);
         i--; 
    }  
}

This works as well.

I had the same problem.

For now, I've settled with client-side Wildcard/Regex filtering based on http://www.codeproject.com/Articles/11556/Converting-Wildcards-to-Regexes?msg=1423024#xx1423024xx - it's simple and works as expected.

I always name year first YYYYMMDD, but wanted to add time. Here you will see that he has given a reason why 0,2 will not work and 1,1 will, because (space) is an invalid character. This opened my eyes to the issue. Also, by default you're in 24hr mode.

Note before you read the rest: The shell script shown here is certainly not safe to use and well tested. Use at your own risk!

I wrote a bash script to accomplish that task. Suppose your library is lib1 and the one you need to include some symbols from is lib2. The script now runs in a loop, where it first checks which undefined symbols from lib1 can be found in lib2. It then extracts the corresponding object files from lib2 with ar, renames them a bit, and puts them into lib1. Now there may be more missing symbols, because the stuff you included from lib2 needs other stuff from lib2, which we haven't included yet, so the loop needs to run again. If after some passes of the loop there are no changes anymore, i.e. no object files from lib2 added to lib1, the loop can stop.

Note, that the included symbols are still reported as undefined by nm, so I'm keeping track of the object files, that were added to lib1, themselves, in order to determine whether the loop can be stopped.

#! /bin/bash

lib1="$1"
lib2="$2"

if [ ! -e $lib1.backup ]; then
    echo backing up
    cp $lib1 $lib1.backup
fi

remove_later=""

new_tmp_file() {
    file=$(mktemp)
    remove_later="$remove_later $file"
    eval $1=$file
}
remove_tmp_files() {
    rm $remove_later
}
trap remove_tmp_files EXIT

find_symbols() {
    nm $1 $2 | cut -c20- | sort | uniq 
}

new_tmp_file currsymbols

while true; do
    ((pass++))
    echo "Starting pass #$pass"
    curr=$lib1
    find_symbols $curr "--undefined-only" > $currsymbols
    changed=0
    for sym in $(cat $currsymbols); do
        for obj in $(egrep "^$sym in .*\.o" $lib2symbols | cut -d" " -f3); do
            echo "  Found $sym in $obj."
            if [ -e "$prefix$obj" ]; then continue; fi
            echo "    -> Adding $obj to $lib1"
            ar x $lib2 $obj
            mv $obj "$prefix$obj"
            ar -r -s $lib1 "$prefix$obj"
            remove_later="$remove_later $prefix$obj"
            ((changed=changed+1))
        done
    done
    echo "Found $changed changes in pass #$pass"

    if [[ $changed == 0 ]]; then break; fi

I named that script libcomp, so you can call it then e.g. with

./libcomp libmylib.a libwhatever.a

where libwhatever is where you want to include symbols from. However, I think it's safest to copy everything into a separate directory first. I wouldn't trust my script so much (however, it worked for me; I could include libgsl.a into my numerics library with that and leave out that -lgsl compiler switch).

As the lines can be variable in logs I thought it best to take a number of lines per file approach. The following code snippet processed a 4 million line log file in under 19 seconds (18.83.. seconds)splitting it into 500,000 line chunks:

$sourceFile = "c:\myfolder\mylargeTextyFile.csv"
$partNumber = 1
$batchSize = 500000
$pathAndFilename = "c:\myfolder\mylargeTextyFile part $partNumber file.csv"

[System.Text.Encoding]$enc = [System.Text.Encoding]::GetEncoding(65001)  # utf8 this one

$fs=New-Object System.IO.FileStream ($sourceFile,"OpenOrCreate", "Read", "ReadWrite",8,"None") 
$streamIn=New-Object System.IO.StreamReader($fs, $enc)
$streamout = new-object System.IO.StreamWriter $pathAndFilename

$line = $streamIn.readline()
$counter = 0
while ($line -ne $null)
{
    $streamout.writeline($line)
    $counter +=1
    if ($counter -eq $batchsize)
    {
        $partNumber+=1
        $counter =0
        $streamOut.close()
        $pathAndFilename = "c:\myfolder\mylargeTextyFile part $partNumber file.csv"
        $streamout = new-object System.IO.StreamWriter $pathAndFilename

    }
    $line = $streamIn.readline()
}
$streamin.close()
$streamout.close()

This can easily be turned into a function or script file with parameters to make it more versatile. It uses a StreamReader and StreamWriter to achieve its speed and tiny memory footprint

A new C++ Excel extension for PHP, though you'll need to build it yourself, and the docs are pretty sparse when it comes to trying to find out what functionality (I can't even find out from the site what formats it supports, or whether it reads or writes or both.... I'm guessing both) it offers is phpexcellib from SIMITGROUP.

All claim to be faster than PHPExcel from codeplex or from github, but (with the exception of COM, PUNO Ilia's wrapper around libXl and spout) they don't offer both reading and writing, or both xls and xlsx; may no longer be supported; and (while I haven't tested Ilia's extension) only COM and PUNO offers the same degree of control over the created workbook.

If your consuming code can make do with an IDictionary<> interface, instead of Dictionary, my instinct would have been to use a SortedDictionary<> with a custom array comparer, ie:

class ArrayComparer<T> : IComparer<IList<T>>
    where T : IComparable<T>
{
    public int Compare(IList<T> x, IList<T> y)
    {
        int compare = 0;
        for (int n = 0; n < x.Count && n < y.Count; ++n)
        {
            compare = x[n].CompareTo(y[n]);
        }
        return compare;
    }
}

And create thus (using int[] just for concrete example's sake):

var dictionary = new SortedDictionary<int[], string>(new ArrayComparer<int>());

One possible option to implement such behavior is

PUT /groups/api/v1/groups/{group id}/status
{
    "Status":"Activated"
}

And obviously, if someone need to deactivate it, PUT will have Deactivated status in JSON.

In case of necessity of mass activation/deactivation, PATCH can step into the game (not for exact group, but for groups resource:

PATCH /groups/api/v1/groups
{
    { “op”: “replace”, “path”: “/group1/status”, “value”: “Activated” },
    { “op”: “replace”, “path”: “/group7/status”, “value”: “Activated” },
    { “op”: “replace”, “path”: “/group9/status”, “value”: “Deactivated” }
}

In general this is idea as @Andrew Dobrowolski suggesting, but with slight changes in exact realization.

Without the combined child selector you would probably do something similar to this:

foo {
  bar {
    baz {
      color: red;
    }
  }
}

If you want to reproduce the same syntax with >, you could to this:

foo {
  > bar {
    > baz {
      color: red;
    }
  }
}

This compiles to this:

foo > bar > baz {
  color: red;
}

Or in sass:

foo
  > bar
    > baz
      color: red

Always : If you always want vertical scrollbar, use overflow-y: scroll;

jsFiddle:

<div style="overflow-y: scroll;">
......
</div>

When needed: If you only want vertical scrollbar when needed, use overflow-y: auto; (You need to specify a height in this case)

jsFiddle:

<div style="overflow-y: auto; height:150px; ">
....
</div>

Remember that Raspberry Pi does not have real time clock. So even you are connected to internet have to set the time every time you power on or restart.

This is how it works:

1. Type sudo raspi-config in the Raspberry Pi command line
2. Internationalization options
3. Change Time Zone
4. Select geographical area
5. Select city or region
6. Reboot your pi

Next thing you can set time using this command

sudo date -s "Mon Aug  12 20:14:11 UTC 2014"

More about data and time

man date

When Pi is connected to computer should have to manually set data and time

In my case the sha command was missing from my linux distro; steps were

• added the packages for sha512 (on my distro sudo apt install hashalot)
• npm cache verify
• rm -rf node_modules
• npm install

It just means that the server cannot find your image.

Remember The image path must be relative to the CSS file location

Check the path and if the image file exist.

This will get ALL parameters from the request. For Debugging purposes only:

@RequestMapping (value = "/promote", method = {RequestMethod.POST, RequestMethod.GET})
public ModelAndView renderPromotePage (HttpServletRequest request) {
    Map<String, String[]> parameters = request.getParameterMap();

    for(String key : parameters.keySet()) {
        System.out.println(key);
        String[] vals = parameters.get(key);
        for(String val : vals)
            System.out.println(" -> " + val);
    }

    ModelAndView mv = new ModelAndView();
    mv.setViewName("test");
    return mv;
}

In addition to Gilson PJ answer:

 new webpack.optimize.CommonsChunkPlugin('common.js'),
 new webpack.optimize.DedupePlugin(),
 new webpack.optimize.UglifyJsPlugin(),
 new webpack.optimize.AggressiveMergingPlugin()

with

"scripts": {
    "build": "NODE_ENV=production webpack -p --config ./webpack.production.config.js"
},

cause that the it tries to uglify your code twice. See https://webpack.github.io/docs/cli.html#production-shortcut-p for more information.

You can fix this by removing the UglifyJsPlugin from plugins-array or add the OccurrenceOrderPlugin and remove the "-p"-flag. so one possible solution would be

 new webpack.optimize.CommonsChunkPlugin('common.js'),
 new webpack.optimize.DedupePlugin(),
 new webpack.optimize.UglifyJsPlugin(),
 new webpack.optimize.OccurrenceOrderPlugin(),
 new webpack.optimize.AggressiveMergingPlugin()

and

"scripts": {
    "build": "NODE_ENV=production webpack --config ./webpack.production.config.js"
},

You can also try using apply with get method of dictionary, seems to be little faster than replace:

data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)

Testing with timeit:

%%timeit
data['sex'].replace([0,1],['Female','Male'],inplace=True)

Result:

The slowest run took 5.83 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 510 µs per loop

Using apply:

%%timeit
data['sex'] = data['sex'].apply({1:'Male', 0:'Female'}.get)

Result:

The slowest run took 5.92 times longer than the fastest. This could mean that an intermediate result is being cached.
1000 loops, best of 3: 331 µs per loop

Note: apply with dictionary should be used if all the possible values of the columns in the dataframe are defined in the dictionary else, it will have empty for those not defined in dictionary.

I stumble upon this question and it grabbed my interest. The accepted answer is completely correct, but I thought I do provide my findings at JVM byte code level to explain why the OP encounter the ClassCastException.

I have the code which is pretty much the same as OP's code:

public static <T> T convertInstanceOfObject(Object o) {
    try {
       return (T) o;
    } catch (ClassCastException e) {
        return null;
    }
}

public static void main(String[] args) {
    String k = convertInstanceOfObject(345435.34);
    System.out.println(k);
}

and the corresponding byte code is:

public static <T> T convertInstanceOfObject(java.lang.Object);
    Code:
       0: aload_0
       1: areturn
       2: astore_1
       3: aconst_null
       4: areturn
    Exception table:
       from    to  target type
           0     1     2   Class java/lang/ClassCastException

  public static void main(java.lang.String[]);
    Code:
       0: ldc2_w        #3                  // double 345435.34d
       3: invokestatic  #5                  // Method java/lang/Double.valueOf:(D)Ljava/lang/Double;
       6: invokestatic  #6                  // Method convertInstanceOfObject:(Ljava/lang/Object;)Ljava/lang/Object;
       9: checkcast     #7                  // class java/lang/String
      12: astore_1
      13: getstatic     #8                  // Field java/lang/System.out:Ljava/io/PrintStream;
      16: aload_1
      17: invokevirtual #9                  // Method java/io/PrintStream.println:(Ljava/lang/String;)V
      20: return

Notice that checkcast byte code instruction happens in the main method not the convertInstanceOfObject and convertInstanceOfObject method does not have any instruction that can throw ClassCastException. Because the main method does not catch the ClassCastException hence when you execute the main method you will get a ClassCastException and not the expectation of printing null.

Now I modify the code to the accepted answer:

public static <T> T convertInstanceOfObject(Object o, Class<T> clazz) {
        try {
            return clazz.cast(o);
        } catch (ClassCastException e) {
            return null;
        }
    }
    public static void main(String[] args) {
        String k = convertInstanceOfObject(345435.34, String.class);
        System.out.println(k);
    }

The corresponding byte code is:

public static <T> T convertInstanceOfObject(java.lang.Object, java.lang.Class<T>);
    Code:
       0: aload_1
       1: aload_0
       2: invokevirtual #2                  // Method java/lang/Class.cast:(Ljava/lang/Object;)Ljava/lang/Object;
       5: areturn
       6: astore_2
       7: aconst_null
       8: areturn
    Exception table:
       from    to  target type
           0     5     6   Class java/lang/ClassCastException

  public static void main(java.lang.String[]);
    Code:
       0: ldc2_w        #4                  // double 345435.34d
       3: invokestatic  #6                  // Method java/lang/Double.valueOf:(D)Ljava/lang/Double;
       6: ldc           #7                  // class java/lang/String
       8: invokestatic  #8                  // Method convertInstanceOfObject:(Ljava/lang/Object;Ljava/lang/Class;)Ljava/lang/Object;
      11: checkcast     #7                  // class java/lang/String
      14: astore_1
      15: getstatic     #9                  // Field java/lang/System.out:Ljava/io/PrintStream;
      18: aload_1
      19: invokevirtual #10                 // Method java/io/PrintStream.println:(Ljava/lang/String;)V
      22: return

Notice that there is an invokevirtual instruction in the convertInstanceOfObject method that calls Class.cast() method which throws ClassCastException which will be catch by the catch(ClassCastException e) bock and return null; hence, "null" is printed to console without any exception.

Without enumerate():

>>> mylist = ["aa123", "bb2322", "aa354", "cc332", "ab334", "333aa"]
>>> l = [mylist.index(i) for i in mylist if 'aa' in i]
>>> l
[0, 2, 5]

It looks like the events are not bubbling. Try this:

$("#mybutton").click(function(){
  var oldval=$("#mytext").val();
  $("#mytext").val('Changed by button');
  var newval=$("#mytext").val();
  if (newval != oldval) {
    $("#mytext").trigger('change');
  }
});

I hope this helps.

I tried just a plain old $("#mytext").trigger('change') without saving the old value, and the .change fires even if the value didn't change. That is why I saved the previous value and called $("#mytext").trigger('change') only if it changes.

I think you can try this for calling in from a class

 System.Web.HttpContext.Current.Server.MapPath("~/SignatureImages/");

*----------------Sorry I oversight, for static function already answered the question by adrift*

System.Web.Hosting.HostingEnvironment.MapPath("~/SignatureImages/");

Update

I got exception while using System.Web.Hosting.HostingEnvironment.MapPath("~/SignatureImages/");

Ex details : System.ArgumentException: The relative virtual path 'SignatureImages' is not allowed here. at System.Web.VirtualPath.FailIfRelativePath()

Solution (tested in static webmethod)

System.Web.HttpContext.Current.Server.MapPath("~/SignatureImages/"); Worked

What you actually created with:

MyType[] list = []

Was fixed size array (not list) with size of 0. You can create fixed size array of size for example 4 with:

MyType[] array = new MyType[4]

But there's no add method of course.

If you create list with def it's something like creating this instance with Object (You can read more about def here). And [] creates empty ArrayList in this case.

So using def list = [] you can then append new items with add() method of ArrayList

list.add(new MyType())

Or more groovy way with overloaded left shift operator:

list << new MyType() 

Pure JavaScript:

var button = document.getElementById('button'); // Assumes element with id='button'

button.onclick = function() {
    var div = document.getElementById('newpost');
    if (div.style.display !== 'none') {
        div.style.display = 'none';
    }
    else {
        div.style.display = 'block';
    }
};

SEE DEMO

jQuery:

$("#button").click(function() { 
    // assumes element with id='button'
    $("#newpost").toggle();
});

I foolishly had a wrapper div which had a width measured in pixels. The other browsers seemed to be intelligent enough to deal with this. Once I had converted the width to a percentage value, it worked fine on Safari mobile as well. Very annoying.

.page{width: 960px;}

to

.page{width:93.75%}

<div id="divPage" class="page">
</div>

Note: As the original asker implied, if you are setting up two databases on the same machine you probably want to make two schemas instead - in that case you don't need anything special to query across them.

postgres_fdw

Use postgres_fdw (foreign data wrapper) to connect to tables in any Postgres database - local or remote.

Note that there are foreign data wrappers for other popular data sources. At this time, only postgres_fdw and file_fdw are part of the official Postgres distribution.

For Postgres versions before 9.3

Versions this old are no longer supported, but if you need to do this in a pre-2013 Postgres installation, there is a function called dblink.

I've never used it, but it is maintained and distributed with the rest of PostgreSQL. If you're using the version of PostgreSQL that came with your Linux distro, you might need to install a package called postgresql-contrib.

In addition to some of the other answers provided, if you wanted to look at the differences in table structure with a table that might have the similar but differing structure, you could do this in multiple ways:

First - If using Oracle SQL Developer, you could run a describe on both tables to compare them:

descr TABLE_NAME1
descr TABLE_NAME2

Second - The first solution may not be ideal for larger tables with a lot of columns. If you only want to see the differences in the data between the two tables, then as mentioned by several others, using the SQL Minus operator should do the job.

Third - If you are using Oracle SQL Developer, and you want to compare the table structure of two tables using different schemas you can do the following:

1. Select "Tools"
2. Select "Database Diff"
3. Select "Source Connection"
4. Select "Destination Connection"
5. Select the "Standard Object Types" you want to compare
6. Enter the "Table Name"
7. Click "Next" until you reach "Finish"
8. Click "Finish"
9. NOTE: In steps 3 & 4 is where you would select the differing schemas in which the objects exist that you want to compare.

Fourth - If the tables two tables you wish to compare have more columns, are in the same schema, have no need to compare more than two tables and are unappealing to compare visually using the DESCR command you can use the following to compare the differences in the table structure:

select 
     a.column_name    || ' | ' || b.column_name, 
     a.data_type      || ' | ' || b.data_type, 
     a.data_length    || ' | ' || b.data_length, 
     a.data_scale     || ' | ' || b.data_scale, 
     a.data_precision || ' | ' || b.data_precision
from 
     user_tab_columns a,
     user_tab_columns b
where 
     a.table_name = 'TABLE_NAME1' 
and  b.table_name = 'TABLE_NAME2'
and  ( 
       a.data_type      <> b.data_type     or 
       a.data_length    <> b.data_length   or 
       a.data_scale     <> b.data_scale    or 
       a.data_precision <> b.data_precision
     )
and a.column_name = b.column_name;

This is the only proposed method who actually selects the whole row, not only the max(id) field. It uses a subquery

SELECT * FROM permlog WHERE id = ( SELECT MAX( id ) FROM permlog )

I use objects JSON style for dumb structs (no member functions).

meteor add thelohoadmin:bootstrap@=3.3.7 solves the issue. You get the latest bootstrap and no warning messages.

<c:if test="${fn:contains(task.subscribers, customer)}">

This works fine for me.

You can give it a property display block; so it will behave like a div and have its own line

CSS:

.feature_desc {
   display: block;
   ....
}

If you are using Android Studio 3.0 or above make sure your project build.gradle should have content similar to-

buildscript {                 
    repositories {
        google()
        jcenter()
    }
    dependencies {            
        classpath 'com.android.tools.build:gradle:3.0.1'

    }
}

allprojects {
    repositories {
        google()
        jcenter()
    }
}

Note- position really matters add google() before jcenter()

And for below Android Studio 3.0 and starting from support libraries 26.+ your project build.gradle must look like this-

allprojects {
    repositories {
        jcenter()
        maven {
            url "https://maven.google.com"
        }
    }
}

the term "smart pointer" includes shared pointers, auto pointers, locking pointers and others. you meant to say auto pointer (more ambiguously known as "owning pointer"), not smart pointer.

Dumb pointers (T*) are never the best solution. They make you do explicit memory management, which is verbose, error prone, and sometimes nigh impossible. But more importantly, they don't signal your intent.

Auto pointers delete the pointee at destruction. For arrays, prefer encapsulations like vector and deque. For other objects, there's very rarely a need to store them on the heap - just use locals and object composition. Still the need for auto pointers arises with functions that return heap pointers -- such as factories and polymorphic returns.

Shared pointers delete the pointee when the last shared pointer to it is destroyed. This is useful when you want a no-brainer, open-ended storage scheme where expected lifetime and ownership can vary widely depending on the situation. Due to the need to keep an (atomic) counter, they're a bit slower than auto pointers. Some say half in jest that shared pointers are for people who can't design systems -- judge for yourself.

For an essential counterpart to shared pointers, look up weak pointers too.

As another poster said, it's typically preferable to have interfaces define capabilities not types. I would tend not to "implement" something like a "User," and this is why "IUser" often isn't really necessary in the way described here. I often see classes as nouns and interfaces as adjectives:

class Number implements Comparable{...}  
class MyThread implements Runnable{...}
class SessionData implements Serializable{....}

Sometimes an Adjective doesn't make sense, but I'd still generally be using interfaces to model behavior, actions, capabilities, properties, etc,... not types.

Also, If you were really only going to make one User and call it User then what's the point of also having an IUser interface? And if you are going to have a few different types of users that need to implement a common interface, what does appending an "I" to the interface save you in choosing names of the implementations?

I think a more realistic example would be that some types of users need to be able to login to a particular API. We could define a Login interface, and then have a "User" parent class with SuperUser, DefaultUser, AdminUser, AdministrativeContact, etc suclasses, some of which will or won't implement the Login (Loginable?) interface as necessary.

Handle the Worksheet_Change event or the Workbook_SheetChange event.

The event handlers take an argument "Target As Range", so you can check if the range that's changing includes the cell you're interested in.

I had already committed the changes and added all the files, had the same origin as remote, still kept getting that error. My simple solution to this was just:

git push

This can be resolved in resolved with the following steps :

1. $ php artisan cache:clear

2. $ sudo chmod -R 777 storage

3. $ composer dump-autoload

Hope it helps

Use the Tortoise SVN copy functionality to revert commited changes:

1. Right click the parent folder that contains the deleted files/folder
2. Select the "show log"
3. Select and right click on the version before which the changes/deleted was done
4. Select the "browse repository"
5. Select the file/folder which needs to be restored and right click
6. Select "copy to" which will copy the files/folders to the head revision

Hope that helps

Long time no Perl

while(<STDIN>) {
    next unless /:\s*(\S+)\s+\(([^\)]+)\)\s*(\*?)/;
    print "|$1|$2|$3|\n";
}

If you append this to user.js:

exports.User = User;

then in server.js you can do:

var userFile = require('./user.js');
var User = userFile.User;

http://nodejs.org/docs/v0.4.10/api/globals.html#require

Another way is:

global.User = User;

then this would be enough in server.js:

require('./user.js');

Your test requires a ServletContext: add @WebIntegrationTest

@RunWith(SpringJUnit4ClassRunner.class)
@ContextConfiguration(classes = AppConfig.class, loader = AnnotationConfigContextLoader.class)
@WebIntegrationTest
public class UserServiceImplIT

...or look here for other options: https://docs.spring.io/spring-boot/docs/current/reference/html/boot-features-testing.html

UPDATE In Spring Boot 1.4.x and above @WebIntegrationTest is no longer preferred. @SpringBootTest or @WebMvcTest

a very common try_files line which can be applied on your condition is

location / {
    try_files $uri $uri/ /test/index.html;
}

you probably understand the first part, location / matches all locations, unless it's matched by a more specific location, like location /test for example

The second part ( the try_files ) means when you receive a URI that's matched by this block try $uri first, for example http://example.com/images/image.jpg nginx will try to check if there's a file inside /images called image.jpg if found it will serve it first.

Second condition is $uri/ which means if you didn't find the first condition $uri try the URI as a directory, for example http://example.com/images/, ngixn will first check if a file called images exists then it wont find it, then goes to second check $uri/ and see if there's a directory called images exists then it will try serving it.

Side note: if you don't have autoindex on you'll probably get a 403 forbidden error, because directory listing is forbidden by default.

EDIT: I forgot to mention that if you have index defined, nginx will try to check if the index exists inside this folder before trying directory listing.

Third condition /test/index.html is considered a fall back option, (you need to use at least 2 options, one and a fall back), you can use as much as you can (never read of a constriction before), nginx will look for the file index.html inside the folder test and serve it if it exists.

If the third condition fails too, then nginx will serve the 404 error page.

Also there's something called named locations, like this

location @error {
}

You can call it with try_files like this

try_files $uri $uri/ @error;

TIP: If you only have 1 condition you want to serve, like for example inside folder images you only want to either serve the image or go to 404 error, you can write a line like this

location /images {
    try_files $uri =404;
}

which means either serve the file or serve a 404 error, you can't use only $uri by it self without =404 because you need to have a fallback option.
You can also choose which ever error code you want, like for example:

location /images {
    try_files $uri =403;
}

This will show a forbidden error if the image doesn't exist, or if you use 500 it will show server error, etc ..

For 'Hello' at the start of the string:

SELECT STUFF('Hello World', 1, 6, '')

This will work for 'Hello' anywhere in the string:

SELECT REPLACE('Hello World', 'Hello ', '')

I was able to do this:

String a;
if(rs.getString("column") != null)
{
    a = "Hello world!";
}
else
{
    a = "Bye world!";
}

Turn the String into a char[], replace the letter by index, then convert the array back into a String.

String myName = "domanokz";
char[] myNameChars = myName.toCharArray();
myNameChars[4] = 'x';
myName = String.valueOf(myNameChars);

function convert($seconds){
$string = "";

$days = intval(intval($seconds) / (3600*24));
$hours = (intval($seconds) / 3600) % 24;
$minutes = (intval($seconds) / 60) % 60;
$seconds = (intval($seconds)) % 60;

if($days> 0){
    $string .= "$days days ";
}
if($hours > 0){
    $string .= "$hours hours ";
}
if($minutes > 0){
    $string .= "$minutes minutes ";
}
if ($seconds > 0){
    $string .= "$seconds seconds";
}

return $string;
}

echo convert(3744000);

The simplest way is to make String conform to Error:

extension String: Error {}

Then you can just throw a string:

throw "Some Error"

To make the string itself be the localizedString of the error you can instead extend LocalizedError:

extension String: LocalizedError {
    public var errorDescription: String? { return self }
}

Using request with headers and post.

var options = {
            headers: {
                  'Authorization': 'AccessKey ' + token,
                  'Content-Type' : 'application/json'
            },
            uri: 'https://myurl.com/param' + value',
            method: 'POST',
            json: {'key':'value'}
 };
      
 request(options, function (err, httpResponse, body) {
    if (err){
         console.log("Hubo un error", JSON.stringify(err));
    }
    //res.status(200).send("Correcto" + JSON.stringify(body));
 })

Here's the signature.

public static string ActionLink(this HtmlHelper htmlHelper, 
                                string linkText,
                                string actionName,
                                string controllerName,
                                object values, 
                                object htmlAttributes)

What you are doing is mixing the values and the htmlAttributes together. values are for URL routing.

You might want to do this.

@Html.ActionLink(Context.User.Identity.Name, "Index", "Account", null, 
     new { @style="text-transform:capitalize;" });
