UPDATE TableName
 SET YourField = ''
WHERE YourField REGEXP 'YOUR REGEX'

And :

SELECT * from TableName
 WHERE YourField REGEXP 'YOUR REGEX'

Since the .Rows result is marked as consisting of rows, you can "For Each" it to deal with each row individually, like this:

Function Attendance(rng As Range) As Long
Attendance = 0
For Each rRow In rng.Rows
    If WorksheetFunction.Sum(rRow) > 0 Then
        Attendance = Attendance + 1
    End If
Next
End Function

I use this to check attendance in any of a few categories (different columns) for a list of people (different rows).

(And of course you could use .Columns to do a "For Each" over the columns in the range.)

The clone method is Ruby's standard, built-in way to do a shallow-copy:

irb(main):003:0> h0 = {"John" => "Adams", "Thomas" => "Jefferson"}
=> {"John"=>"Adams", "Thomas"=>"Jefferson"}
irb(main):004:0> h1 = h0.clone
=> {"John"=>"Adams", "Thomas"=>"Jefferson"}
irb(main):005:0> h1["John"] = "Smith"
=> "Smith"
irb(main):006:0> h1
=> {"John"=>"Smith", "Thomas"=>"Jefferson"}
irb(main):007:0> h0
=> {"John"=>"Adams", "Thomas"=>"Jefferson"}

Note that the behavior may be overridden:

This method may have class-specific behavior. If so, that behavior will be documented under the #initialize_copy method of the class.

You cau use

ul.nav {
    display: none;
}

This will by default close the navbar. Please let me know anybody finds this usefull

The solution for my case is:

1. Right click the output window;
2. Check the 'Program Output'

Exception object also contains original response e.response, that could be useful if need to see error body in response from the server. For example:

try:
    r = requests.post('somerestapi.com/post-here', data={'birthday': '9/9/3999'})
    r.raise_for_status()
except requests.exceptions.HTTPError as e:
    print (e.response.text)

Yes there is one and it is inside the SQLServer management studio. Unlike the previous versions I think. Follow these simple steps.

1)Right click on a database in the Object explorer 2)Selected New Query from the popup menu 3)Query Analyzer will be opened.

Enjoy work.

You can follow this tutorial on how to use Google Maps for testing on localhost.

• Click this link and follow the process (create new project, API key > Browser key, register 'localhost' domain): https://console.developers.google.com//flows/enableapi?apiid=maps_backend&keyType=CLIENT_SIDE&reusekey=true
• Generate the key
• Deploy Google Maps widget as described here: http://www2.microstrategy.com/producthelp/10/GISHelp/Lang_1033/GIS_Integration.htm
• Add your Google Maps API key to googleConfig.xml (as desribed in the previous link) ENTER_YOUR_KEY_HERE
• Restart Web Server

Hope this helps!

Try below code

 string Name = "Abhishek";
 string firstfour = Name.Substring(0, 4);
 Response.Write(firstfour);

In your particular case the issue seem to be with accessing the site from non-canonical url (www.site.com vs. site.com).

Instead of fixing CORS issue (which may require writing proxy to server fonts with proper CORS headers depending on service provider) you can normalize your Urls to always server content on canonical Url and simply redirect if one requests page without "www.".

Alternatively you can upload fonts to different server/CDN that is known to have CORS headers configured or you can easily do so.

Say you have a download function to download a file from network, and want to be notified when download task has finished.

typealias CompletionHandler = (success:Bool) -> Void

func downloadFileFromURL(url: NSURL,completionHandler: CompletionHandler) {

    // download code.

    let flag = true // true if download succeed,false otherwise

    completionHandler(success: flag)
}

// How to use it.

downloadFileFromURL(NSURL(string: "url_str")!, { (success) -> Void in

    // When download completes,control flow goes here.
    if success {
        // download success
    } else {
        // download fail
    }
})

Hope it helps.

The code is okay but you are in the wrong directory. You must run these commands inside your rails project-directory.

The normal way to get there from scratch is:

$ rails new PROJECT_NAME
$ cd PROJECT_NAME
$ rails generate model ad \
    name:string \ 
    description:text \
    price:decimal \
    seller_id:integer \
    email:string img_url:string

This is the best way to get a schema dynamically and add it to the different tables within a database in order to get other information dynamically

select @sql = 'insert #tables SELECT ''[''+SCHEMA_NAME(schema_id)+''.''+name+'']'' AS SchemaTable FROM sys.tables'

exec (@sql)

of course #tables is a dynamic table in the stored procedure

I used:

Tel: <a href="tel:+123 123456789">+123 123456789</a>

and the result is:

Tel: +123 123456789

Where "Tel:" stands for pure text and only the number is coded and clickable.

To accomplish the same thing...

1. Stage just the files you want to work on.
2. git commit -m 'temp'
3. git add .
4. git stash
5. git reset HEAD~1

Boom. The files you don't want are stashed. The files you want are all ready for you.

The most simple way is using type casting:

public char toChar(int c) {
    return (char)c;
}

If you want to revert the file to its state in master:

git checkout origin/master [filename]

Two years later (Found this on Google, so for anyone else)... As has been mentioned above, you don't need to select anything. These three lines:

Workbooks(File).Worksheets(SheetData).Range("A1").Select
Workbooks(File).Worksheets(SheetData).Range(Selection, Selection.End(xlToRight)).Select
Workbooks(File).Worksheets(SheetData).Selection.Copy ActiveWorkbook.Sheets(sheetName).Cells(1, 1)

Can be replaced with

Workbooks(File).Worksheets(SheetData).Range(Workbooks(File).Worksheets(SheetData). _
Range("A1"), Workbooks(File).Worksheets(SheetData).Range("A1").End(xlToRight)).Copy _
Destination:=ActiveWorkbook.Sheets(sheetName).Cells(1, 1)

This should get around the select error.

You can use some thing like this

OIDs being phased out

The core team responsible for Postgres is gradually phasing out OIDs.

Postgres 12 removes special behavior of OID columns

The use of OID as an optional system column on your tables is now removed from Postgres 12. You can no longer use:

• CREATE TABLE … WITH OIDS command
• default_with_oids (boolean) compatibility setting

The data type OID remains in Postgres 12. You can explicitly create a column of the type OID.

After migrating to Postgres 12, any optionally-defined system column oid will no longer be invisible by default. Performing a SELECT * will now include this column. Note that this extra “surprise” column may break naïvely written SQL code.

The C++11 standard introduced uniform initialization which makes this much simpler if your compiler supports it:

//myClass.hpp
class myClass {
  private:
    static map<int,int> myMap;
};

//myClass.cpp
map<int,int> myClass::myMap = {
   {1, 2},
   {3, 4},
   {5, 6}
};

See also this section from Professional C++, on unordered_maps.

BigDecimal isn't a primitive, so you cannot use the <, > operators. However, since it's a Comparable, you can use the compareTo(BigDecimal) to the same effect. E.g.:

public class Domain {
    private BigDecimal unitPrice;

    public boolean isCheaperThan(BigDecimal other) {
        return unitPirce.compareTo(other.unitPrice) < 0;
    }

    // etc...
}

Notepad++ changed in the past couple of years, and it requires a few extra steps to set up a dark theme.

The answer by Amit-IO is good, but the example theme that is needed has stopped being maintained. The DraculaTheme is active. Just download the XML and put it in a themes folder. You may need Admin access in Windows.

There are two important concepts in multithreading environment:

1. atomicity
2. visibility

The volatile keyword eradicates visibility problems, but it does not deal with atomicity. volatile will prevent the compiler from reordering instructions which involve a write and a subsequent read of a volatile variable; e.g. k++. Here, k++ is not a single machine instruction, but three:

1. copy the value to a register;
2. increment the value;
3. place it back.

So, even if you declare a variable as volatile, this will not make this operation atomic; this means another thread can see a intermediate result which is a stale or unwanted value for the other thread.

On the other hand, AtomicInteger, AtomicReference are based on the Compare and swap instruction. CAS has three operands: a memory location V on which to operate, the expected old value A, and the new value B. CAS atomically updates V to the new value B, but only if the value in V matches the expected old value A; otherwise, it does nothing. In either case, it returns the value currently in V. The compareAndSet() methods of AtomicInteger and AtomicReference take advantage of this functionality, if it is supported by the underlying processor; if it is not, then the JVM implements it via spin lock.

The working command I'm using to execute custom SQL statements is:

results = ActiveRecord::Base.connection.execute("foo")

with "foo" being the sql statement( i.e. "SELECT * FROM table").

This command will return a set of values as a hash and put them into the results variable.

So on my rails application_controller.rb I added this:

def execute_statement(sql)
  results = ActiveRecord::Base.connection.execute(sql)

  if results.present?
    return results
  else
    return nil
  end
end

Using execute_statement will return the records found and if there is none, it will return nil.

This way I can just call it anywhere on the rails application like for example:

records = execute_statement("select * from table")

"execute_statement" can also call NuoDB procedures, functions, and also Database Views.

For anyone who stumbles across this in the future, this is how you do it:

xl.Range("A1:A1").Style := "Bad"
xl.Range("A1:A1").Style := "Good"
xl.Range("A1:A1").Style := "Neutral"

An easy way to check on things like this is to open excel and record a macro. In this case I recorded a macro where I just formatted the cell to "Bad". Once you've recorded the macro, just go in and edit it and it will essentially give you the code. It will require a little translation on your part, but here is what the macro looks like when I edit it:

 Selection.Style = "Bad"

As you can see, it's pretty easy to make the jump to AHK from what excel provides.

I also posted an answer to a related question here.

what jamietre said, but

Private Sub SomeVBASub
    Cancel=False
    DoStuff
    If not Cancel Then DoAnotherStuff
    If not Cancel Then AndFinallyDothis
End Sub

I think you should try this:

string path = Path.GetRandomFileName();
path = Path.Combine(@"c:\temp", path);
path = Path.ChangeExtension(path, ".tmp");
File.Create(path);

It generates a unique filename and creates a file with that file name at a specified location.

your folder name is scripts..

and you are Referencing it like ../script/login.js

Also make sure that script folder is in your project directory

Thanks

Java API specifies two methods you could use: indexOf(Object obj) and lastIndexOf(Object obj). The first one returns the index of the element if found, -1 otherwise. The second one returns the last index, that would be like searching the list backwards.

Yes, what you are asking for is called AJAX or XMLHttpRequest. You can either use a library like jQuery to simplify making the call (due to cross-browser compatibility issues), or write your own handler.

In jQuery:

$.GET('url.asp', {data: 'here'}, function(data){ /* what to do with the data returned */ })

In plain vanilla javaScript (from w3c):

var xmlhttp;
function loadXMLDoc(url)
{
    xmlhttp=null;
if (window.XMLHttpRequest)
  {// code for all new browsers
      xmlhttp=new XMLHttpRequest();
  }
else if (window.ActiveXObject)
  {// code for IE5 and IE6
      xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
  }
if (xmlhttp!=null)
  {
      xmlhttp.onreadystatechange=state_Change;
      xmlhttp.open("GET",url,true);
      xmlhttp.send(null);
  }
else
  {
      alert("Your browser does not support XMLHTTP.");
  }
}

function state_Change()
{
    if (xmlhttp.readyState==4)
      {// 4 = "loaded"
          if (xmlhttp.status==200)
            {// 200 = OK
             //xmlhttp.data and shtuff
            // ...our code here...
        }
  else
        {
            alert("Problem retrieving data");
        }
  }
}

First, find the hash you want to your submodule to reference. then run

~/supery/subby $ git co hashpointerhere
~/supery/subby $ cd ../
~/supery $ git add subby
~/supery $ git commit -m 'updated subby reference'

that has worked for me to get my submodule to the correct hash reference and continue on with my work without getting any further conflicts.

Since Windows >=Vista/Server 2008, RegGetValue is available, which is a safer function than RegQueryValueEx. No need for RegOpenKeyEx, RegCloseKey or NUL termination checks of string values (REG_SZ, REG_MULTI_SZ, REG_EXPAND_SZ).

Its parameter dwFlags supports flags for type restriction, filling the value buffer with zeros on failure (RRF_ZEROONFAILURE) and 32/64bit registry access (RRF_SUBKEY_WOW6464KEY, RRF_SUBKEY_WOW6432KEY) for 64bit programs.

You should pass a pointer if you are going to modify the value of the variable. Even though technically passing a reference or a pointer are the same, passing a pointer in your use case is more readable as it "advertises" the fact that the value will be changed by the function.

You cannot always make a branch or pull an existing branch and push back to it, because you are not registered as a collaborator for that specific project.

Forking is nothing more than a clone on the GitHub server side:

• without the possibility to directly push back
• with fork queue feature added to manage the merge request

You keep a fork in sync with the original project by:

• adding the original project as a remote
• fetching regularly from that original project
• rebase your current development on top of the branch of interest you got updated from that fetch.

The rebase allows you to make sure your changes are straightforward (no merge conflict to handle), making your pulling request that more easy when you want the maintainer of the original project to include your patches in his project.

The goal is really to allow collaboration even though direct participation is not always possible.

The fact that you clone on the GitHub side means you have now two "central" repository ("central" as "visible from several collaborators).
If you can add them directly as collaborator for one project, you don't need to manage another one with a fork.

The merge experience would be about the same, but with an extra level of indirection (push first on the fork, then ask for a pull, with the risk of evolutions on the original repo making your fast-forward merges not fast-forward anymore).
That means the correct workflow is to git pull --rebase upstream (rebase your work on top of new commits from upstream), and then git push --force origin, in order to rewrite the history in such a way your own commits are always on top of the commits from the original (upstream) repo.

• Pull new updates from original Github repository into forked Github repository

Here's how I get there using Version 3.0.6 on Windows

Another way would be to use glue package:

glue_collapse(glue("{sdata}"))
paste(glue("{sdata}"), collapse = '')

This is impossible as you cannot return from an asynchronous call inside a synchronous method.

In this case you need to pass a callback to foo that will receive the return value

function foo(address, fn){
  geocoder.geocode( { 'address': address}, function(results, status) {
     fn(results[0].geometry.location); 
  });
}

foo("address", function(location){
  alert(location); // this is where you get the return value
});

The thing is, if an inner function call is asynchronous, then all the functions 'wrapping' this call must also be asynchronous in order to 'return' a response.

If you have a lot of callbacks you might consider taking the plunge and use a promise library like Q.

For the times when some fields have a ";" and some do not you can also add a semi-colon to the field and use the same method described.

SET MyText = LEFT(MyText+';', CHARINDEX(';',MyText+';')-1)

I prefer using Hamcrest because it gives much better output in case of a failure

Assert.assertThat(listUnderTest, 
       IsIterableContainingInOrder.contains(expectedList.toArray()));

Instead of reporting

expected true, got false

it will report

expected List containing "1, 2, 3, ..." got list containing "4, 6, 2, ..."

IsIterableContainingInOrder.contain

Hamcrest

According to the Javadoc:

Creates a matcher for Iterables that matches when a single pass over the examined Iterable yields a series of items, each logically equal to the corresponding item in the specified items. For a positive match, the examined iterable must be of the same length as the number of specified items

So the listUnderTest must have the same number of elements and each element must match the expected values in order.

404 - Not Found - can be used for The URI requested is invalid or the resource requested such as a user, does not exists.

It is important to note that object files are assembled to binary code in a format that is relocatable. This is a form which allows the assembled code to be loaded anywhere into memory for use with other programs by a linker.

Instructions that refer to labels will not yet have an address assigned for these labels in the .o file.

These labels will be written as '0' and the assembler creates a relocation record for these unknown addresses. When the file is linked and output to an executable the unknown addresses are resolved and the program can be executed.

You can use the nm tool on an object file to list the symbols defined in a .o file.

You are overwriting the start date object with the value of a DOM Element with an id of Startdate.

This should work:

var start = new Date(document.getElementById('Stardate').value);

var y = start.getFullYear();

It depends on how the code in the first file is structured.

If it's just a bunch of functions, like:

# first.py
def foo(): print("foo")
def bar(): print("bar")

Then you could import it and use the functions as follows:

# second.py
import first

first.foo()    # prints "foo"
first.bar()    # prints "bar"

or

# second.py
from first import foo, bar

foo()          # prints "foo"
bar()          # prints "bar"

or, to import all the names defined in first.py:

# second.py
from first import *

foo()          # prints "foo"
bar()          # prints "bar"

Note: This assumes the two files are in the same directory.

It gets a bit more complicated when you want to import names (functions, classes, etc) from modules in other directories or packages.

For the absolute coordinates of any jquery element I wrote this function, it probably doesnt work for all css position types but maybe its a good start for someone ..

function AbsoluteCoordinates($element) {
    var sTop = $(window).scrollTop();
    var sLeft = $(window).scrollLeft();
    var w = $element.width();
    var h = $element.height();
    var offset = $element.offset(); 
    var $p = $element;
    while(typeof $p == 'object') {
        var pOffset = $p.parent().offset();
        if(typeof pOffset == 'undefined') break;
        offset.left = offset.left + (pOffset.left);
        offset.top = offset.top + (pOffset.top);
        $p = $p.parent();
    }

    var pos = {
          left: offset.left + sLeft,
          right: offset.left + w + sLeft,
          top:  offset.top + sTop,
          bottom: offset.top + h + sTop,
    }
    pos.tl = { x: pos.left, y: pos.top };
    pos.tr = { x: pos.right, y: pos.top };
    pos.bl = { x: pos.left, y: pos.bottom };
    pos.br = { x: pos.right, y: pos.bottom };
    //console.log( 'left: ' + pos.left + ' - right: ' + pos.right +' - top: ' + pos.top +' - bottom: ' + pos.bottom  );
    return pos;
}

If you define

    #!/bin/bash
        fun1(){
          echo "Fun1 from file1 $1"
        }
fun1 Hello
. file2 
fun1 Hello
exit 0

in file1(chmod 750 file1) and file2

   fun1(){
      echo "Fun1 from file2 $1"
    }
    fun2(){
      echo "Fun1 from file1 $1"
    }

and run ./file2 you'll get Fun1 from file1 Hello Fun1 from file2 Hello Surprise!!! You overwrite fun1 in file1 with fun1 from file2... So as not to do so you must

declare -f pr_fun1=$fun1
. file2
unset -f fun1
fun1=$pr_fun1
unset -f pr_fun1
fun1 Hello

it's save your previous definition for fun1 and restore it with the previous name deleting not needed imported one. Every time you import functions from another file you may remember two aspects:

1. you may overwrite existing ones with the same names(if that the thing you want you must preserve them as described above)
2. import all content of import file(functions and global variables too) Be careful! It's dangerous procedure

We can use the raw_input() function in Python 2 and the input() function in Python 3. By default the input function takes an input in string format. For other data type you have to cast the user input.

In Python 2 we use the raw_input() function. It waits for the user to type some input and press return and we need to store the value in a variable by casting as our desire data type. Be careful when using type casting

x = raw_input("Enter a number: ") #String input

x = int(raw_input("Enter a number: ")) #integer input

x = float(raw_input("Enter a float number: ")) #float input

x = eval(raw_input("Enter a float number: ")) #eval input

In Python 3 we use the input() function which returns a user input value.

x = input("Enter a number: ") #String input

If you enter a string, int, float, eval it will take as string input

x = int(input("Enter a number: ")) #integer input

If you enter a string for int cast ValueError: invalid literal for int() with base 10:

x = float(input("Enter a float number: ")) #float input

If you enter a string for float cast ValueError: could not convert string to float

x = eval(input("Enter a float number: ")) #eval input

If you enter a string for eval cast NameError: name ' ' is not defined Those error also applicable for Python 2.

I'm using fixed width string-parts (padded with whitespace) to avoid having the formatter mess up my SQL string indentation. This gives you mixed results, and won't work where whitespace is not ignored as it is in SQL, but can be helpful.

    final String sql = "SELECT v.value FROM properties p               "
            + "JOIN property_values v ON p.property_id = v.property_id "
            + "WHERE p.product_id = ?                                  "
            + "AND v.value        IS NOT NULL                          ";

For enabling readonly:

$("#descrip").attr("readonly","true");

For disabling readonly

$("#descrip").attr("readonly","");

For those of you who use ASP.net with VB razor the ternary operator is also possible.

It must be, as well, inside a razor expression:

@(Razor_Expression)

and the ternary operator works as follows:

If(BooleanTestExpression, "TruePart", "FalsePart")

The same code example shown here with VB razor looks like this:

<a class="@(If(User.Identity.IsAuthenticated, "auth", "anon"))">My link here</a>

Note: when writing a TextExpression remember that Boolean symbols are not the same between C# and VB.

Your "listen" directives are wrong. See this page: http://nginx.org/en/docs/http/server_names.html.

They should be

server {
    listen      80;
    server_name www.domain1.com;
    root /var/www/domain1;
}

server {
    listen       80;
    server_name www.domain2.com;
    root /var/www/domain2;
}

Note, I have only included the relevant lines. Everything else looked okay but I just deleted it for clarity. To test it you might want to try serving a text file from each server first before actually serving php. That's why I left the 'root' directive in there.

Profilers are definitely a good way to get numbers, but in my experience, perceived performance is all that matters to the user/client. For example, we had a project with an Ext accordion that expanded to show some data and then a few nested Ext grids. Everything was actually rendering pretty fast, no single operation took a long time, there was just a lot of information being rendered all at once, so it felt slow to the user.

We 'fixed' this, not by switching to a faster component, or optimizing some method, but by rendering the data first, then rendering the grids with a setTimeout. So, the information appeared first, then the grids would pop into place a second later. Overall, it took slightly more processing time to do it that way, but to the user, the perceived performance was improved.

These days, the Chrome profiler and other tools are universally available and easy to use, as are console.time(), console.profile(), and performance.now(). Chrome also gives you a timeline view which can show you what is killing your frame rate, where the user might be waiting, etc.

Finding documentation for all these tools is really easy, you don't need an SO answer for that. 7 years later, I'll still repeat the advice of my original answer and point out that you can have slow code run forever where a user won't notice it, and pretty fast code running where they do, and they will complain about the pretty fast code not being fast enough. Or that your request to your server API took 220ms. Or something else like that. The point remains that if you take a profiler out and go looking for work to do, you will find it, but it may not be the work your users need.

Here is a fast and easy way of parsing query strings in JavaScript:

function getQueryVariable(variable) {
    var query = window.location.search.substring(1);
    var vars = query.split('&');
    for (var i = 0; i < vars.length; i++) {
        var pair = vars[i].split('=');
        if (decodeURIComponent(pair[0]) == variable) {
            return decodeURIComponent(pair[1]);
        }
    }
    console.log('Query variable %s not found', variable);
}

Now make a request to page.html?x=Hello:

console.log(getQueryVariable('x'));

If you want a one-liner from numpy and aren't too concerned about performance, try:

np.sum(np.diag(the_array,1),0)[:-1]

Explanation: np.diag(the_array,1) creates a matrix with your array one-off the diagonal, np.sum(...,0) sums the matrix column-wise, and ...[:-1] takes the elements that would correspond to the size of the original array. Playing around with the 1 and :-1 as parameters can give you shifts in different directions.

Well the best way to get round corners fast and with standard animation is to create a copy of the control template with Blend. Once you get a copy set the corner radius on the Grid tag and you should be able to have your control with full animation functionality and applyable to any button control. look this is the code:

<ControlTemplate x:Key="ButtonControlTemplate" TargetType="Button">        
    <Grid x:Name="RootGrid" Background="{TemplateBinding Background}"
          CornerRadius="8,8,8,8">

        <!--</Border>-->
    </Grid>        
</ControlTemplate>

I also edited the VisualState="PointerOver" specifically at Storyboard.TargetName="BorderBrush", because its ThemeResource get squared corners whenever PointerOver triggers.

Then you should be able to apply it to your control style like this:

<Style TargetType="ContentControl" x:Key="ButtonLoginStyle"
       BasedOn="{StaticResource CommonLoginStyleMobile}">
    <Setter Property="FontWeight" Value="Bold"/>
    <Setter Property="Background" Value="#002060"/>
    <Setter Property="Template" Value="{StaticResource ButtonControlTemplate}"/>        
</Style>

So you can apply your styles to any Button.

Create a Java like HashMap in PHP with O(1) read complexity.

Open a phpsh terminal:

php> $myhashmap = array();
php> $myhashmap['mykey1'] = 'myvalue1';
php> $myhashmap['mykey2'] = 'myvalue2';
php> echo $myhashmap['mykey2'];
myvalue2

The complexity of the $myhashmap['mykey2'] in this case appears to be constant time O(1), meaning that as the size of $myhasmap approaches infinity, the amount of time it takes to retrieve a value given a key stays the same.

Evidence the php array read is constant time:

Run this through the PHP interpreter:

php> for($x = 0; $x < 1000000000; $x++){
 ... $myhashmap[$x] = $x . " derp";
 ... }

The loop adds 1 billion key/values, it takes about 2 minutes to add them all to the hashmap which may exhaust your memory.

Then see how long it takes to do a lookup:

php> system('date +%N');echo "  " . $myhashmap[10333] . "  ";system('date +%N');
786946389  10333 derp  789008364

So how fast is the PHP array map lookup?

The 10333 is the key we looked up. 1 million nanoseconds == 1 millisecond. The amount of time it takes to get a value from a key is 2.06 million nanoseconds or about 2 milliseconds. About the same amount of time if the array were empty. This looks like constant time to me.

This is nuts! How does Oracle provide an installer that doesn't install anything!?

Anyways for me it was:

sudo rm /usr/bin/java
sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.8.0_31.jdk/Contents/Home/jre/bin/java /usr/bin/java

where 1.8.0_31 is your installed java version...

Java's Runtime object can report the JVM's memory usage. For CPU consumption you'll have to use an external utility, like Unix's top or Windows Process Manager.

I am not sure if this is what you are looking for

if var<>"" then
           dosomething

or

if isempty(thisworkbook.sheets("sheet1").range("a1").value)= false then

the ISEMPTY function can be used as well

After like 48 hours of research, I ended up doing this to get proportional scaling:

NOTE: This sample is written with React. If you aren't using that, change the camel case stuff back to hyphens (ie: change backgroundColor to background-color and change the style Object back to a String).

<div
  style={{
    backgroundColor: 'lightpink',
    resize: 'horizontal',
    overflow: 'hidden',
    width: '1000px',
    height: 'auto',
  }}
>
  <svg
    width="100%"
    viewBox="113 128 972 600"
    preserveAspectRatio="xMidYMid meet"
  >
    <g> ... </g>
  </svg>
</div>

Here's what is happening in the above sample code:

VIEWBOX

MDN: https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/viewBox

min-x, min-y, width and height

ie: viewbox="0 0 1000 1000"

Viewbox is an important attribute because it basically tells the SVG what size to draw and where. If you used CSS to make the SVG 1000x1000 px but your viewbox was 2000x2000, you would see the top-left quarter of your SVG.

The first two numbers, min-x and min-y, determine if the SVG should be offset inside the viewbox.

My SVG needs to shift up/down or left/right

Examine this: viewbox="50 50 450 450"

The first two numbers will shift your SVG left 50px and up 50px, and the second two numbers are the viewbox size: 450x450 px. If your SVG is 500x500 but it has some extra padding on it, you can manipulate those numbers to move it around inside the "viewbox".

Your goal at this point is to change one of those numbers and see what happens.

You can also completely omit the viewbox, but then your milage will vary depending on every other setting you have at the time. In my experience, you will encounter issues with preserving aspect ratio because the viewbox helps define the aspect ratio.

PRESERVE ASPECT RATIO

MDN: https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/preserveAspectRatio

Based on my research, there are lots of different aspect ratio settings, but the default one is called xMidYMid meet. I put it on mine to explicitly remind myself. xMidYMid meet makes it scale proportionately based on the midpoint X and Y. This means it stays centered in the viewbox.

WIDTH

MDN: https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/width

Look at my example code above. Notice how I set only width, no height. I set it to 100% so it fills the container it is in. This is what is probably contributing the most to answering this Stack Overflow question.

You can change it to whatever pixel value you want, but I'd recommend using 100% like I did to blow it up to max size and then control it with CSS via the parent container. I recommend this because you will get "proper" control. You can use media queries and you can control the size without crazy JavaScript.

SCALING WITH CSS

Look at my example code above again. Notice how I have these properties:

resize: 'horizontal', // you can safely omit this
overflow: 'hidden',   // if you use resize, use this to fix weird scrollbar appearance
width: '1000px',
height: 'auto',

This is additional, but it shows you how to allow the user to resize the SVG while maintaining the proper aspect ratio. Because the SVG maintains its own aspect ratio, you only need to make width resizable on the parent container, and it will resize as desired.

We leave height alone and/or set it to auto, and we control the resizing with width. I picked width because it is often more meaningful due to responsive designs.

Here is an image of these settings being used:

If you read every solution in this question and are still confused or don't quite see what you need, check out this link here. I found it very helpful:

https://css-tricks.com/scale-svg/

It's a massive article, but it breaks down pretty much every possible way to manipulate an SVG, with or without CSS. I recommend reading it while casually drinking a coffee or your choice of select liquids.

Honestly, with 8 objects max and 8 properties max per object, your best bet is to just traverse each object and make the comparisons directly. It'll be fast and it'll be easy.

If you're going to be using these types of comparisons often, then I agree with Jason about JSON serialization...but otherwise there's no need to slow down your app with a new library or JSON serialization code.

To Fix The "Missing "server" JVM at C:\Program Files\Java\jre7\bin\server\jvm­­.dll, please install or use the JRE or JDK that contains these missing components.

Follow these steps:

Go to oracle.com and install Java JRE7 (Check if Java 6 is not installed already)

After that, go to C:/Program files/java/jre7/bin

Here, create an folder called Server

Now go into the C:/Program files/java/jre7/bin/client folder

Copy all the data in this folder into the new C:/Program files/java/jre7/bin/Server folder

Example to get the last input element:

document.querySelector(".groups-container >div:last-child input")

Employees.objects.values_list('eng_name', flat=True)

That creates a flat list of all eng_names. If you want more than one field per row, you can't do a flat list: this will create a list of tuples:

Employees.objects.values_list('eng_name', 'rank')

e.relatedTarget.data('load-url'); won't work
use dataset.loadUrl

$('#myModal').on('show.bs.modal', function (e) {
    var loadurl = e.relatedTarget.dataset.loadUrl;
    $(this).find('.modal-body').load(loadurl);
});

You need to combine multiple classes (col-*-offset-* for left-margin and col-*-pull-* to pull it right)

<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>_x000D_

So you don't need to separate it manually into different rows.

unittest comes with the standard library, but I would recomend you nosetests.

"nose extends unittest to make testing easier."

I would also recomend you pylint

"analyzes Python source code looking for bugs and signs of poor quality."

All major browsers now include native JSON encoding/decoding.

// To encode an object (This produces a string)
var json_str = JSON.stringify(myobject); 

// To decode (This produces an object)
var obj = JSON.parse(json_str);

Note that only valid JSON data will be encoded. For example:

var obj = {'foo': 1, 'bar': (function (x) { return x; })}
JSON.stringify(obj) // --> "{\"foo\":1}"

Valid JSON types are: objects, strings, numbers, arrays, true, false, and null.

Some JSON resources:

• JSON on Mozilla Developer Network
• JSON on Wikipedia

One way to handle this is to put the information as an attribute on the primary one. I must stress, I really think this is the appropriate thing to do only when the two pieces of information are related such that one has information about the other.

For example, I sometimes stash the name of "crucial variables" or variables that have been significantly modified by storing a list of variable names as an attribute on the data frame:

attr(my.DF, 'Modified.Variables') <- DVs.For.Analysis$Names.of.Modified.Vars
return(my.DF)

This allows me to store a list of variable names with the data frame itself.

Yes, in order for the z-index to work, you'll need to give the element a position: absolute or a position: relative property.

But... pay attention to parents!

You have to go up the nodes of the elements to check if at the level of the common parent the first descendants have a defined z-index.

All other descendants can never be in the foreground if at the base there is a lower definite z-index.

In this snippet example, div1-2-1 has a z-index of 1000 but is nevertheless under the div1-1-1 which has a z-index of 3.

This is because div1-1 has a z-index greater than div1-2.

.div {
  
}

#div1 {
  z-index: 1;
  position: absolute;
  width: 500px;
  height: 300px;
  border: 1px solid black;
}

#div1-1 {
  z-index: 2;
  position: absolute;
  left: 230px;
  width: 200px;
  height: 200px;
  top: 31px;
  background-color: indianred;
}

#div1-1-1 {
  z-index: 3;
  position: absolute;
  top: 50px;
  width: 100px;
  height: 100px;
  background-color: burlywood;
}

#div1-2 {
  z-index: 1;
  position: absolute;
  width: 200px;
  height: 200px;

  background-color: red;
}

#div1-2-1 {

After a while trying to build a function to get an integer with the last row in a single column, this worked fine:

    function lastRow() {
    var spreadsheet = SpreadsheetApp.getActiveSheet();
    spreadsheet.getRange('B1').activate();
    var columnB = spreadsheet.getSelection().getNextDataRange(SpreadsheetApp.Direction.DOWN).activate();
    var numRows = columnB.getLastRow();
    var nextRow = numRows + 1; 
    }

I know this is an old question, but the accepted solution didn't quite match what I needed it to do. So, I refined it to accept various line terminators (rather than just line feed) and to use a specified character encoding (rather than ISO-8859-n). All in one method (refactor as appropriate):

public static long getLinesCount(String fileName, String encodingName) throws IOException {
    long linesCount = 0;
    File file = new File(fileName);
    FileInputStream fileIn = new FileInputStream(file);
    try {
        Charset encoding = Charset.forName(encodingName);
        Reader fileReader = new InputStreamReader(fileIn, encoding);
        int bufferSize = 4096;
        Reader reader = new BufferedReader(fileReader, bufferSize);
        char[] buffer = new char[bufferSize];
        int prevChar = -1;
        int readCount = reader.read(buffer);
        while (readCount != -1) {
            for (int i = 0; i < readCount; i++) {
                int nextChar = buffer[i];
                switch (nextChar) {
                    case '\r': {
                        // The current line is terminated by a carriage return or by a carriage return immediately followed by a line feed.
                        linesCount++;
                        break;
                    }
                    case '\n': {
                        if (prevChar == '\r') {
                            // The current line is terminated by a carriage return immediately followed by a line feed.
                            // The line has already been counted.
                        } else {
                            // The current line is terminated by a line feed.
                            linesCount++;
                        }
                        break;
                    }
                }
                prevChar = nextChar;
            }
            readCount = reader.read(buffer);
        }
        if (prevCh != -1) {
            switch (prevCh) {
                case '\r':
                case '\n': {
                    // The last line is terminated by a line terminator.
                    // The last line has already been counted.
                    break;
                }
                default: {
                    // The last line is terminated by end-of-file.
                    linesCount++;
                }
            }
        }
    } finally {
        fileIn.close();
    }
    return linesCount;
}

This solution is comparable in speed to the accepted solution, about 4% slower in my tests (though timing tests in Java are notoriously unreliable).

Get hrtime as single number in one line:

const begin = process.hrtime();
// ... Do the thing you want to measure
const nanoSeconds = process.hrtime(begin).reduce((sec, nano) => sec * 1e9 + nano)

Array.reduce, when given a single argument, will use the array's first element as the initial accumulator value. One could use 0 as the initial value and this would work as well, but why do the extra * 0.

Seeing that it appears you are running using the SQL syntax, try with the correct wild card.

SELECT * FROM someTable WHERE (someTable.Field NOT LIKE '%RISK%') AND (someTable.Field NOT LIKE '%Blah%') AND someTable.SomeOtherField <> 4; 

I prefer to read and write clean code - as outlined in "Clean Code" by Robert C. Martin. When following his credo you should not require the developer (as user of your API) to know the (internal) structure of your array.

The API user may ask: Is that an array with one dimension only? Are the objects spread around on all levels of a multi dimensional array? How many nested loops (foreach, etc.) do i need to access all objects? What type of objects are "stored" in that array?

As you outlined you want to use that array (which contains objects) as a one dimensional array.

As outlined by Nishi you can use:

/**
 * @return SomeObj[]
 */

for that.

But again: be aware - this is not a standard docblock notation. This notation was introduced by some IDE producers.

Okay, okay, as a developer you know that "[]" is tied to an array in PHP. But what do a "something[]" mean in normal PHP context? "[]" means: create new element within "something". The new element could be everything. But what you want to express is: array of objects with the same type and it´s exact type. As you can see, the IDE producer introduces a new context. A new context you had to learn. A new context other PHP developers had to learn (to understand your docblocks). Bad style (!).

Because your array do have one dimension you maybe want to call that "array of objects" a "list". Be aware that "list" has a very special meaning in other programming languages. It would be mutch better to call it "collection" for example.

Remember: you use a programming language that enables you all options of OOP. Use a class instead of an array and make your class traversable like an array. E.g.:

class orderCollection implements ArrayIterator

Or if you want to store the internal objects on different levels within an multi dimensional array/object structure:

class orderCollection implements RecursiveArrayIterator

This solution replaces your array by an object of type "orderCollection", but do not enable code completion within your IDE so far. Okay. Next step:

Implement the methods that are introduced by the interface with docblocks - particular:

/**
 * [...]
 * @return Order
 */
orderCollection::current()

/**
 * [...]
 * @return integer E.g. database identifier of the order
 */
orderCollection::key()

/**
 * [...]
 * @return Order
 */
orderCollection::offsetGet()

Do not forget to use type hinting for:

orderCollection::append(Order $order)
orderCollection::offsetSet(Order $order)

This solution stops introducing a lot of:

/** @var $key ... */
/** @var $value ... */

all over your code files (e.g. within loops), as Zahymaka confirmed with her/his answer. Your API user is not forced to introduce that docblocks, to have code completion. To have @return on only one place reduces the redundancy (@var) as mutch as possible. Sprinkle "docBlocks with @var" would make your code worst readable.

Finaly you are done. Looks hard to achive? Looks like taking a sledgehammer to crack a nut? Not realy, since you are familiar with that interfaces and with clean code. Remember: your source code is written once / read many.

If code completion of your IDE do not work with this approach, switch to a better one (e.g. IntelliJ IDEA, PhpStorm, Netbeans) or file a feature request on the issue tracker of your IDE producer.

Thanks to Christian Weiss (from Germany) for being my trainer and for teaching me such a great stuff. PS: Meet me and him on XING.

Add white-space: nowrap to the container element:

CSS:

* {
    box-sizing: border-box;
}
.row {
    vertical-align: top;
    white-space: nowrap;
}
.column{
    float: left;
    display: inline-block;
    width: 50% // Or whatever in your case
}

HTML:

<div class="row">
    <div class="column"> Some stuff</div>
    <div class="column">Some other stuff</div>
</div>

Here is the Plunker.

You have to write a specific media query for this, from your question, below 768px, the navbar will collapse, so apply it above 768px and below 1000px, just like that:

@media (min-width: 768px) and (max-width: 1000px) {
   .collapse {
       display: none !important;
   }
}

This will hide the navbar collapse until the default occurrence of the bootstrap unit. As the collapse class flips the inner assets inside navbar collapse will be automatically hidden, like wise you have to set your css as you desired design.

Better just create a XLSX file with field names on top row. Create it manually or using Mockaroo. Export it to Excel(or CSV) and then import it to Access using New Data Source -> From File

IMHO it's the best and most performant way to do it in Access.

One path to take is to

1. Add the file you're working with to the classpath

2. Use the resource loader to locate the file:

       URL url = Test.class.getClassLoader().getResource("myfile.txt");
       System.out.println(url.getPath());
       ...
   

3. Open it

Say you have the following DataFrame:

>>> df = pd.DataFrame([['hello', 'hello world'], ['abcd', 'defg']], columns=['a','b'])
>>> df
       a            b
0  hello  hello world
1   abcd         defg

You can always use the in operator in a lambda expression to create your filter.

>>> df.apply(lambda x: x['a'] in x['b'], axis=1)
0     True
1    False
dtype: bool

The trick here is to use the axis=1 option in the apply to pass elements to the lambda function row by row, as opposed to column by column.

Only want to clone the structure of table:

CREATE TABLE foo SELECT * FROM bar WHERE 1 = 2;

Also wants to copy the data:

CREATE TABLE foo as SELECT * FROM bar;

Construct some data

df <- data.frame( name=c("John", "Adam"), date=c(3, 5) )

Extract exact matches:

subset(df, date==3)

  name date
1 John    3

Extract matches in range:

subset(df, date>4 & date<6)

  name date
2 Adam    5

The following syntax produces identical results:

df[df$date>4 & df$date<6, ]

  name date
2 Adam    5

All these basic commands are part of the coreutils package.

You can find all information you need here:

http://www.gnu.org/software/coreutils/

If you want to download the latest source, you should use git:

git clone git://git.sv.gnu.org/coreutils

To install git on your Ubuntu machine, you should use apt-get (git is not included in the standard Ubuntu installation):

sudo apt-get install git

Truth to be told, here you can find specific source for the ls command:

http://git.savannah.gnu.org/cgit/coreutils.git/tree/src/ls.c

Only 4984 code lines for a command 'easy enough' as ls... are you still interested in reading it?? Good luck! :D

Create a configuration file and put your entries there.

SERVER_PORT=10000     
THREAD_POOL_COUNT=3     
ROOT_DIR=/home/   

You can load this file using Properties.load(fileName) and retrieved values you get(key);

You can use the * operator before an iterable to expand it within the function call. For example:

timeseries_list = [timeseries1 timeseries2 ...]
r = scikits.timeseries.lib.reportlib.Report(*timeseries_list)

(notice the * before timeseries_list)

From the python documentation:

If the syntax *expression appears in the function call, expression must evaluate to an iterable. Elements from this iterable are treated as if they were additional positional arguments; if there are positional arguments x1, ..., xN, and expression evaluates to a sequence y1, ..., yM, this is equivalent to a call with M+N positional arguments x1, ..., xN, y1, ..., yM.

This is also covered in the python tutorial, in a section titled Unpacking argument lists, where it also shows how to do a similar thing with dictionaries for keyword arguments with the ** operator.

Maybe this quick, dirty solution will work?

public class A {
    static int UNIQUE_ID = 0;
    int uid = ++UNIQUE_ID;

    public int hashCode() {
        return uid;
    }
}

This also gives the number of instance of a class being initialized.

You can use Array.prototype.find function in javascript. Array find MDN.

So to find string in array of string, the code becomes very simple. Plus as browser implementation, it will provide good performance.

Ex.

var strs = ['abc', 'def', 'ghi', 'jkl', 'mno'];
var value = 'abc';
strs.find(
    function(str) {
        return str == value;
    }
);

or using lambda expression it will become much shorter

var strs = ['abc', 'def', 'ghi', 'jkl', 'mno'];
var value = 'abc';
strs.find((str) => str === value);

Via css. Put this inside the <head> tag.

<style type="text/css" media="screen">

table{
border-collapse:collapse;
border:1px solid #FF0000;
}

table td{
border:1px solid #FF0000;
}
</style>

Reset the file in a correct state, commit, and push again.

If you're sure nobody else has fetched your changes yet, you can use --amend when committing, to modify your previous commit (i.e. rewrite history), and then push. I think you'll have to use the -f option when pushing, to force the push, though.

In case we want all the Person (instead of only one Person) in the returning dictionary, we could:

var _people = personList
.GroupBy(p => p.FirstandLastName)
.ToDictionary(g => g.Key, g => g.Select(x=>x));

These methods works on the locks and locks are associated with Object and not Threads. Hence, it is in Object class.

The methods wait(), notify() and notifyAll() are not only just methods, these are synchronization utility and used in communication mechanism among threads in Java.

More detailed answer to help the newbies of VueJS:

• First define your router object, select the mode you seem fit. You can declare your routes inside the routes list.
• Next you would want your main app to know router exists, so declare it inside the main app declaration .
• Lastly they $route instance holds all the information about the current route. The code will console log just the parameter passed in the url. (*Mounted is similar to document.ready , .ie its called as soon as the app is ready)

And the code itself:

<script src="https://unpkg.com/vue-router"></script>
var router = new VueRouter({
    mode: 'history',
    routes: []
});
var vm =  new Vue({
    router,
    el: '#app',
    mounted: function() {
        q = this.$route.query.q
        console.log(q)
    },
});

Use changelists. The advantage over specifying files is that you can visualize and confirm everything you wanted is actually included before you commit.

$ svn changelist fix-issue-237 foo.c 
Path 'foo.c' is now a member of changelist 'fix-issue-237'.

That done, svn now keeps things separate for you. This helps when you're juggling multiple changes

$ svn status
A       bar.c
A       baz.c

--- Changelist 'fix-issue-237':
A       foo.c

Finally, tell it to commit what you wanted changed.

$ svn commit --changelist fix-issue-237 -m "Issue 237"

Encapsulation: hiding data using getters and setters etc.

Abstraction: hiding implementation using abstract classes and interfaces etc.

Try this

{{ Request::segment(1) }}

In batch, the > is a redirection sign used to output data into a text file. The compare op's available (And recommended) for cmd are below (quoted from the if /? help):

where compare-op may be one of:

    EQU - equal
    NEQ - not equal
    LSS - less than
    LEQ - less than or equal
    GTR - greater than
    GEQ - greater than or equal

That should explain what you want. The only other compare-op is == which can be switched with the if not parameter. Other then that rely on these three letter ones.

A handy way to achieve this would be:

df.groupby('a').agg({'b':lambda x: list(x)})

A realtime priority thread can never be pre-empted by timer interrupts and runs at a higher priority than any other thread in the system. As such a CPU bound realtime priority thread can totally ruin a machine.

Creating realtime priority threads requires a privilege (SeIncreaseBasePriorityPrivilege) so it can only be done by administrative users.

For Vista and beyond, one option for applications that do require that they run at realtime priorities is to use the Multimedia Class Scheduler Service (MMCSS) and let it manage your threads priority. The MMCSS will prevent your application from using too much CPU time so you don't have to worry about tanking the machine.

Woff is a compressed (zipped) form of the TrueType - OpenType font. It is small and can be delivered over the network like a graphic file. Most importantly, this way the font is preserved completely including rendering rule tables that very few people care about because they use only Latin script.

Take a look at [dead URL removed]. The font you see is an experimental web delivered smartfont (woff) that has thousands of combined characters making complex shapes. The underlying text is simple Latin code of romanized Singhala. (Copy and paste to Notepad and see).

Only woff can do this because nobody has this font and yet it is seen anywhere (Mac, Win, Linux and even on smartphones by all browsers except by IE. IE does not have full support for Open Types).

}

I'll broadly agree with Vagrant on the cause:

1. your action was executing, writing markup to response stream
2. the stream was unbuffered forcing the response headers to get written before the markup writing could begin.
3. Your view encountered a runtime error
4. Exception handler kicks in trying to set the status code to something else non-200
5. Fails because the headers have already been sent.

Where I disagree with Vagrant is the "cause no errors in binding" remedy - you could still encounter runtime errors in View binding e.g. null reference exceptions.

A better solution for this is to ensure that Response.BufferOutput = true; before any bytes are sent to the Response stream. e.g. in your controller action or On_Begin_Request in application. This enables server transfers, cookies/headers to be set etc. right the way up to naturally ending response, or calling end/flush.

Of course also check that buffer isn't being flushed/set to false further down in the stack too.

Just to let you know: I just tried it using a vCard 2.1 file created according to the vCard 2.1 spec. I found that vCard 2.1, despite being an old version, already covered everything I needed, including a base64-encoded photo and international character sets.

It worked perfectly on my unmodified Android 4.1.1 device (Galaxy S3). It also worked on an old iPhone 3GS (iOS 5, via the Evernote app) and a coworker's unmodified old Android 2.1 device. You only need to set the Content-disposition to attachment as suggested above.

A minor problem was that I triggered the VCF download using a QR code, which I scanned with the Microsoft Tag app. That app told me Android couldn't handle the text/x-vcard media type (or just text/vcard, no matter). Once I opened the link in a Web browser (I tried Chrome and the Android default browser), it worked fine.

What Is It?

This exception means that you're trying to access a collection item by index, using an invalid index. An index is invalid when it's lower than the collection's lower bound or greater than or equal to the number of elements it contains.

When It Is Thrown

Given an array declared as:

byte[] array = new byte[4];

You can access this array from 0 to 3, values outside this range will cause IndexOutOfRangeException to be thrown. Remember this when you create and access an array.

Array Length
In C#, usually, arrays are 0-based. It means that first element has index 0 and last element has index Length - 1 (where Length is total number of items in the array) so this code doesn't work:

array[array.Length] = 0;

Moreover please note that if you have a multidimensional array then you can't use Array.Length for both dimension, you have to use Array.GetLength():

int[,] data = new int[10, 5];
for (int i=0; i < data.GetLength(0); ++i) {
    for (int j=0; j < data.GetLength(1); ++j) {
        data[i, j] = 1;
    }
}

Upper Bound Is Not Inclusive
In the following example we create a raw bidimensional array of Color. Each item represents a pixel, indices are from (0, 0) to (imageWidth - 1, imageHeight - 1).

Color[,] pixels = new Color[imageWidth, imageHeight];
for (int x = 0; x <= imageWidth; ++x) {
    for (int y = 0; y <= imageHeight; ++y) {
        pixels[x, y] = backgroundColor;
    }
}

This code will then fail because array is 0-based and last (bottom-right) pixel in the image is pixels[imageWidth - 1, imageHeight - 1]:

pixels[imageWidth, imageHeight] = Color.Black;

In another scenario you may get ArgumentOutOfRangeException for this code (for example if you're using GetPixel method on a Bitmap class).

Arrays Do Not Grow
An array is fast. Very fast in linear search compared to every other collection. It is because items are contiguous in memory so memory address can be calculated (and increment is just an addition). No need to follow a node list, simple math! You pay this with a limitation: they can't grow, if you need more elements you need to reallocate that array (this may take a relatively long time if old items must be copied to a new block). You resize them with Array.Resize<T>(), this example adds a new entry to an existing array:

Array.Resize(ref array, array.Length + 1);

Don't forget that valid indices are from 0 to Length - 1. If you simply try to assign an item at Length you'll get IndexOutOfRangeException (this behavior may confuse you if you think they may increase with a syntax similar to Insert method of other collections).

Special Arrays With Custom Lower Bound
First item in arrays has always index 0. This is not always true because you can create an array with a custom lower bound:

var array = Array.CreateInstance(typeof(byte), new int[] { 4 }, new int[] { 1 });

In that example, array indices are valid from 1 to 4. Of course, upper bound cannot be changed.

Wrong Arguments
If you access an array using unvalidated arguments (from user input or from function user) you may get this error:

private static string[] RomanNumbers =
    new string[] { "I", "II", "III", "IV", "V" };

public static string Romanize(int number)
{
    return RomanNumbers[number];
}

Unexpected Results
This exception may be thrown for another reason too: by convention, many search functions will return -1 (nullables has been introduced with .NET 2.0 and anyway it's also a well-known convention in use from many years) if they didn't find anything. Let's imagine you have an array of objects comparable with a string. You may think to write this code:

// Items comparable with a string
Console.WriteLine("First item equals to 'Debug' is '{0}'.",
    myArray[Array.IndexOf(myArray, "Debug")]);

// Arbitrary objects
Console.WriteLine("First item equals to 'Debug' is '{0}'.",
    myArray[Array.FindIndex(myArray, x => x.Type == "Debug")]);

This will fail if no items in myArray will satisfy search condition because Array.IndexOf() will return -1 and then array access will throw.

Next example is a naive example to calculate occurrences of a given set of numbers (knowing maximum number and returning an array where item at index 0 represents number 0, items at index 1 represents number 1 and so on):

static int[] CountOccurences(int maximum, IEnumerable<int> numbers) {
    int[] result = new int[maximum + 1]; // Includes 0

    foreach (int number in numbers)
        ++result[number];

    return result;
}

Of course, it's a pretty terrible implementation but what I want to show is that it'll fail for negative numbers and numbers above maximum.

How it applies to List<T>?

Same cases as array - range of valid indexes - 0 (List's indexes always start with 0) to list.Count - accessing elements outside of this range will cause the exception.

Note that List<T> throws ArgumentOutOfRangeException for the same cases where arrays use IndexOutOfRangeException.

Unlike arrays, List<T> starts empty - so trying to access items of just created list lead to this exception.

var list = new List<int>();

Common case is to populate list with indexing (similar to Dictionary<int, T>) will cause exception:

list[0] = 42; // exception
list.Add(42); // correct

IDataReader and Columns
Imagine you're trying to read data from a database with this code:

using (var connection = CreateConnection()) {
    using (var command = connection.CreateCommand()) {
        command.CommandText = "SELECT MyColumn1, MyColumn2 FROM MyTable";

        using (var reader = command.ExecuteReader()) {
            while (reader.Read()) {
                ProcessData(reader.GetString(2)); // Throws!
            }
        }
    }
}

GetString() will throw IndexOutOfRangeException because you're dataset has only two columns but you're trying to get a value from 3rd one (indices are always 0-based).

Please note that this behavior is shared with most IDataReader implementations (SqlDataReader, OleDbDataReader and so on).

You can get the same exception also if you use the IDataReader overload of the indexer operator that takes a column name and pass an invalid column name.
Suppose for example that you have retrieved a column named Column1 but then you try to retrieve the value of that field with

 var data = dr["Colum1"];  // Missing the n in Column1.

This happens because the indexer operator is implemented trying to retrieve the index of a Colum1 field that doesn't exist. The GetOrdinal method will throw this exception when its internal helper code returns a -1 as the index of "Colum1".

Others
There is another (documented) case when this exception is thrown: if, in DataView, data column name being supplied to the DataViewSort property is not valid.

How to Avoid

In this example, let me assume, for simplicity, that arrays are always monodimensional and 0-based. If you want to be strict (or you're developing a library), you may need to replace 0 with GetLowerBound(0) and .Length with GetUpperBound(0) (of course if you have parameters of type System.Array, it doesn't apply for T[]). Please note that in this case, upper bound is inclusive then this code:

for (int i=0; i < array.Length; ++i) { }

Should be rewritten like this:

for (int i=array.GetLowerBound(0); i <= array.GetUpperBound(0); ++i) { }

Please note that this is not allowed (it'll throw InvalidCastException), that's why if your parameters are T[] you're safe about custom lower bound arrays:

void foo<T>(T[] array) { }

void test() {
    // This will throw InvalidCastException, cannot convert Int32[] to Int32[*]
    foo((int)Array.CreateInstance(typeof(int), new int[] { 1 }, new int[] { 1 }));
}

Validate Parameters
If index comes from a parameter you should always validate them (throwing appropriate ArgumentException or ArgumentOutOfRangeException). In the next example, wrong parameters may cause IndexOutOfRangeException, users of this function may expect this because they're passing an array but it's not always so obvious. I'd suggest to always validate parameters for public functions:

static void SetRange<T>(T[] array, int from, int length, Func<i, T> function)
{
    if (from < 0 || from>= array.Length)
        throw new ArgumentOutOfRangeException("from");

    if (length < 0)
        throw new ArgumentOutOfRangeException("length");

    if (from + length > array.Length)
        throw new ArgumentException("...");

    for (int i=from; i < from + length; ++i)
        array[i] = function(i);
}

If function is private you may simply replace if logic with Debug.Assert():

Debug.Assert(from >= 0 && from < array.Length);

Check Object State
Array index may not come directly from a parameter. It may be part of object state. In general is always a good practice to validate object state (by itself and with function parameters, if needed). You can use Debug.Assert(), throw a proper exception (more descriptive about the problem) or handle that like in this example:

class Table {
    public int SelectedIndex { get; set; }
    public Row[] Rows { get; set; }

    public Row SelectedRow {
        get {
            if (Rows == null)
                throw new InvalidOperationException("...");

            // No or wrong selection, here we just return null for
            // this case (it may be the reason we use this property
            // instead of direct access)
            if (SelectedIndex < 0 || SelectedIndex >= Rows.Length)
                return null;

            return Rows[SelectedIndex];
        }
}

Validate Return Values
In one of previous examples we directly used Array.IndexOf() return value. If we know it may fail then it's better to handle that case:

int index = myArray[Array.IndexOf(myArray, "Debug");
if (index != -1) { } else { }

How to Debug

In my opinion, most of the questions, here on SO, about this error can be simply avoided. The time you spend to write a proper question (with a small working example and a small explanation) could easily much more than the time you'll need to debug your code. First of all, read this Eric Lippert's blog post about debugging of small programs, I won't repeat his words here but it's absolutely a must read.

You have source code, you have exception message with a stack trace. Go there, pick right line number and you'll see:

array[index] = newValue;

You found your error, check how index increases. Is it right? Check how array is allocated, is coherent with how index increases? Is it right according to your specifications? If you answer yes to all these questions, then you'll find good help here on StackOverflow but please first check for that by yourself. You'll save your own time!

A good start point is to always use assertions and to validate inputs. You may even want to use code contracts. When something went wrong and you can't figure out what happens with a quick look at your code then you have to resort to an old friend: debugger. Just run your application in debug inside Visual Studio (or your favorite IDE), you'll see exactly which line throws this exception, which array is involved and which index you're trying to use. Really, 99% of the times you'll solve it by yourself in a few minutes.

If this happens in production then you'd better to add assertions in incriminated code, probably we won't see in your code what you can't see by yourself (but you can always bet).

The VB.NET side of the story

Everything that we have said in the C# answer is valid for VB.NET with the obvious syntax differences but there is an important point to consider when you deal with VB.NET arrays.

In VB.NET, arrays are declared setting the maximum valid index value for the array. It is not the count of the elements that we want to store in the array.

' declares an array with space for 5 integer 
' 4 is the maximum valid index starting from 0 to 4
Dim myArray(4) as Integer

So this loop will fill the array with 5 integers without causing any IndexOutOfRangeException

For i As Integer = 0 To 4
    myArray(i) = i
Next

The VB.NET rule

This exception means that you're trying to access a collection item by index, using an invalid index. An index is invalid when it's lower than the collection's lower bound or greater than equal to the number of elements it contains. the maximum allowed index defined in the array declaration

Alternative

Using the example from Sarfraz above.

<div class="res">
    <a class="info_link" href="~/Resumes/Resumes1271354404687.docx">
        ~/Resumes/Resumes1271354404687.docx
    </a>
</div>

For href:

$(function(){
  $('.res').on('click', '.info_link', function(){
    alert($(this)[0].href);
  });
});

Used the build-helper-maven-plugin from the post - and update src/main/generated. And mvn clean compile works on my ../common/src/main/java, or on ../common, so kept the latter. Then yes, confirming that IntelliJ IDEA (ver 10.5.2) level of the compilation failed as David Phillips mentioned. The issue was that IDEA did not add another source root to the project. Adding it manually solved the issue. It's not nice as editing anything in the project should come from maven and not from direct editing of IDEA's project options. Yet I will be able to live with it until they support build-helper-maven-plugin directly such that it will auto add the sources.

Then needed another workaround to make this work though. Since each time IDEA re-imported maven settings after a pom change me newly added source was kept on module, yet it lost it's Source Folders selections and was useless. So for IDEA - need to set these once:

• Select - Project Settings / Maven / Importing / keep source and test folders on reimport.
• Add - Project Structure / Project Settings / Modules / {Module} / Sources / Add Content Root.

Now keeping those folders on import is not the best practice in the world either, ..., but giving it a try.

The current answer didn't work for me with Bootstrap 3.1.1. Here's what I had to override:

.form-control:focus {
  border-color: inherit;
  -webkit-box-shadow: none;
  box-shadow: none;

Please search the site before asking questions next time: how to concatenate two dictionaries to create a new one in Python?

The easiest way to do it is to simply use your example code, but using the items() member of each dictionary. So, the code would be:

dic0 = {'dic0': 0}
dic1 = {'dic1': 1}
dic2 = dict(dic0.items() + dic1.items())

I tested this in IDLE and it works fine. However, the previous question on this topic states that this method is slow and chews up memory. There are several other ways recommended there, so please see that if memory usage is important.

In general, i.e. unlimited decimal places:

^-?(([1-9]\d*)|0)(.0*[1-9](0*[1-9])*)?$

can use this to redirect

echo '<meta http-equiv="refresh" content="1; URL=index.php" />';

the content=1 can be change to different value to increase the delay before redirection

In case you are appending to the DOM, make sure the content is compatible:

modal.find ('div.modal-body').append (content) // check content

It's really interesting case. Actually in your setup the following statement is true:

binary_crossentropy = len(class_id_index) * categorical_crossentropy

This means that up to a constant multiplication factor your losses are equivalent. The weird behaviour that you are observing during a training phase might be an example of a following phenomenon:

1. At the beginning the most frequent class is dominating the loss - so network is learning to predict mostly this class for every example.
2. After it learnt the most frequent pattern it starts discriminating among less frequent classes. But when you are using adam - the learning rate has a much smaller value than it had at the beginning of training (it's because of the nature of this optimizer). It makes training slower and prevents your network from e.g. leaving a poor local minimum less possible.

That's why this constant factor might help in case of binary_crossentropy. After many epochs - the learning rate value is greater than in categorical_crossentropy case. I usually restart training (and learning phase) a few times when I notice such behaviour or/and adjusting a class weights using the following pattern:

class_weight = 1 / class_frequency

This makes loss from a less frequent classes balancing the influence of a dominant class loss at the beginning of a training and in a further part of an optimization process.

EDIT:

Actually - I checked that even though in case of maths:

binary_crossentropy = len(class_id_index) * categorical_crossentropy

should hold - in case of keras it's not true, because keras is automatically normalizing all outputs to sum up to 1. This is the actual reason behind this weird behaviour as in case of multiclassification such normalization harms a training.

A boolean is not an integer; 1 and 0 are not boolean values in Java. You'll need to convert them explicitly:

boolean multipleContacts = (1 == jsonObject.getInt("MultipleContacts"));

or serialize the ints as booleans from the start.

PostgreSQL 12 supports generated columns:

PostgreSQL 12 Beta 1 Released!

Generated Columns

PostgreSQL 12 allows the creation of generated columns that compute their values with an expression using the contents of other columns. This feature provides stored generated columns, which are computed on inserts and updates and are saved on disk. Virtual generated columns, which are computed only when a column is read as part of a query, are not implemented yet.

Generated Columns

A generated column is a special column that is always computed from other columns. Thus, it is for columns what a view is for tables.

CREATE TABLE people (
    ...,
    height_cm numeric,
    height_in numeric GENERATED ALWAYS AS (height_cm * 2.54) STORED
);

to remove symbol use tag [ ]

step:1

[]

step 2:place what symbol u want to remove eg:@ like [@]

[@]

step 3:

var name = name.replace(/[@]/g, "");

thats it

var name="ggggggg@fffff"
var result = name.replace(/[@]/g, "");
console .log(result)

Pug (renamed from 'Jade') is a templating engine for full stack web app development. It provides a neat and clean syntax for writing HTML and maintains strict whitespace indentation (like Python). It has been implemented with JavaScript APIs. The language mainly supports two iteration constructs: each and while. 'for' can be used instead 'each'. Kindly consult the language reference here:

https://pugjs.org/language/iteration.html

Here is one of my snippets: each/for iteration in pug_screenshot

    private class GoogleShortenedURLResponse
    {
        public string id { get; set; }
        public string kind { get; set; }
        public string longUrl { get; set; }
    }

    private class GoogleShortenedURLRequest
    {
        public string longUrl { get; set; }
    }

    public ActionResult Index1()
    {
        return View();
    }

    [AcceptVerbs(HttpVerbs.Post)]
    public ActionResult ShortenURL(string longurl)
    {
        string googReturnedJson = string.Empty;
        JavaScriptSerializer javascriptSerializer = new JavaScriptSerializer();

        GoogleShortenedURLRequest googSentJson = new GoogleShortenedURLRequest();
        googSentJson.longUrl = longurl;
        string jsonData = javascriptSerializer.Serialize(googSentJson);

        byte[] bytebuffer = Encoding.UTF8.GetBytes(jsonData);

        WebRequest webreq = WebRequest.Create("https://www.googleapis.com/urlshortener/v1/url");
        webreq.Method = WebRequestMethods.Http.Post;
        webreq.ContentLength = bytebuffer.Length;
        webreq.ContentType = "application/json";

        using (Stream stream = webreq.GetRequestStream())
        {
            stream.Write(bytebuffer, 0, bytebuffer.Length);
            stream.Close();
        }

        using (HttpWebResponse webresp = (HttpWebResponse)webreq.GetResponse())
        {
            using (Stream dataStream = webresp.GetResponseStream())
            {
                using (StreamReader reader = new StreamReader(dataStream))
                {
                    googReturnedJson = reader.ReadToEnd();
                }
            }
        }

        //GoogleShortenedURLResponse googUrl = javascriptSerializer.Deserialize<googleshortenedurlresponse>(googReturnedJson);

        //ViewBag.ShortenedUrl = googUrl.id;
        return View();
    }

Other than the append function, if by "multiple values" you mean another list, you can simply concatenate them like so.

>>> a = [1,2,3]
>>> b = [4,5,6]
>>> a + b
[1, 2, 3, 4, 5, 6]

OK, considering that you are using Windows, the most simple way to do that is to use the standard ftp tool bundled with it. I base the following solution on Windows XP, hoping it'll work as well (or with minor modifications) on other versions.

First of all, you need to create a batch (script) file for the ftp program, containing instructions for it. Name it as you want, and put into it:

curl -u login:pass ftp.myftpsite.com/iiumlabs* -O

open ftp.myftpsite.com
login
pass
mget *
quit

The first line opens a connection to the ftp server at ftp.myftpsite.com. The two following lines specify the login, and the password which ftp will ask for (replace login and pass with just the login and password, without any keywords). Then, you use mget * to get all files. Instead of the *, you can use any wildcard. Finally, you use quit to close the ftp program without interactive prompt.

If you needed to enter some directory first, add a cd command before mget. It should be pretty straightforward.

Finally, write that file and run ftp like this:

ftp -i -s:yourscript

where -i disables interactivity (asking before downloading files), and -s specifies path to the script you created.

Sadly, file transfer over SSH is not natively supported in Windows. But for that case, you'd probably want to use PuTTy tools anyway. The one of particular interest for this case would be pscp which is practically the PuTTy counter-part of the openssh scp command.

The syntax is similar to copy command, and it supports wildcards:

pscp -batch [email protected]:iiumlabs* .

If you authenticate using a key file, you should pass it using -i path-to-key-file. If you use password, -pw pass. It can also reuse sessions saved using PuTTy, using the load -load your-session-name argument.

Considering the answer:

HttpWebRequest webRequest;

void StartWebRequest()
{
    webRequest.BeginGetResponse(new AsyncCallback(FinishWebRequest), null);
}

void FinishWebRequest(IAsyncResult result)
{
    webRequest.EndGetResponse(result);
}

You could send the request pointer or any other object like this:

void StartWebRequest()
{
    HttpWebRequest webRequest = ...;
    webRequest.BeginGetResponse(new AsyncCallback(FinishWebRequest), webRequest);
}

void FinishWebRequest(IAsyncResult result)
{
    HttpWebResponse response = (result.AsyncState as HttpWebRequest).EndGetResponse(result) as HttpWebResponse;
}

Greetings

I have tested a full layout using flexbox it contains header, footer, main body with left, center and right panels and the panels can contain menu items or footer and headers that should scroll. Pretty complex

IE11 and even IE EDGE have some problems displaying the flex content but it can be overcome. I have tested it in most browsers and it seems to work.

Some fixed i have applies are IE11 height bug, Adding height:100vh and min-height:100% to the html/body. this also helps to not have to set height on container in the dom. Also make the body/html a flex container. Otherwise IE11 will compress the view.

html,body {
    display: flex;
    flex-flow:column nowrap;
    height:100vh; /* fix IE11 */
    min-height:100%; /* fix IE11 */  
}

A fix for IE EDGE that overflows the flex container: overflow:hidden on main flex container. if you remove the overflow, IE EDGE wil push the content out of the viewport instead of containing it inside the flex main container.

main{
    flex:1 1 auto;
    overflow:hidden; /* IE EDGE overflow fix */  
}

You can see my testing and example on my codepen page. I remarked the important css parts with the fixes i have applied and hope someone finds it useful.

Try this:

public static String reverse(String str) {
   return (str == null || str.length()==0) ? str : reverseString2(str.substring(1))+str.charAt(0);
}

that syntax is now deprecated, you will get this error:

org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:
WorkflowScript: 14: Expected a stage @ line 14, column 9.
       parallel firstTask: {
       ^

WorkflowScript: 14: Stage does not have a name @ line 14, column 9.
       parallel secondTask: {
       ^

2 errors

You should do something like:

stage("Parallel") {
    steps {
        parallel (
            "firstTask" : {
                //do some stuff
            },
            "secondTask" : {
                // Do some other stuff in parallel
            }
        )
    }
}

Just to add the use of node here, to distribute jobs across multiple build servers/ VMs:

pipeline {
  stages {
    stage("Work 1"){
     steps{
      parallel ( "Build common Library":   
            {
              node('<Label>'){
                  /// your stuff
                  }
            },

        "Build Utilities" : {
            node('<Label>'){
               /// your stuff
              }
           }
         )
    }
}

All VMs should be labelled as to use as a pool.

Step 1: Create a filter component by implementing Filter interface.

@Component
public class PerformanceFilter implements Filter {

    @Override
    public void doFilter(ServletRequest request, ServletResponse response, FilterChain chain)
            throws IOException, ServletException {

            ......
            ......
    }

}

Step 2: Set this filter to the uri patterns using FilterRegistrationBean.

@Configuration
public class FilterConfig {
    @Bean
    public FilterRegistrationBean<PerformanceFilter> perfFilter() {
        FilterRegistrationBean<PerformanceFilter> registration = new FilterRegistrationBean<>();
        registration.setFilter(new PerformanceFilter());
        registration.addUrlPatterns("/*");
        return registration;
    }
}

I wanted to see all the indices for the colnames because I needed to do a complicated column rearrangement, so I printed the colnames as a dataframe. The rownames are the indices.

as.data.frame(colnames(df))

1 A
2 B
3 C

The cex parameter will do that for you.

a <- c(3, 2, 2, 2, 1, 2 )
barplot(a, beside = T,
        col = 1:6, space = c(0, 2))
legend("topright", 
       legend = c("a", "b", "c", "d", "e", "f"), 
       fill = 1:6, ncol = 2,
       cex = 0.75)

You need to set the g flag to replace globally:

date.replace(new RegExp("/", "g"), '')
// or
date.replace(/\//g, '')

Otherwise only the first occurrence will be replaced.

its super easy.

You'll need each machine to have it's own copy of ElasticSearch (simply copy the one you have now) -- the reason is that each machine / node whatever is going to keep it's own files that are sharded accross the cluster.

The only thing you really need to do is edit the config file to include the name of the cluster.

If all machines have the same cluster name elasticsearch will do the rest automatically (as long as the machines are all on the same network)

Read here to get you started: https://www.elastic.co/guide/en/elasticsearch/guide/current/deploy.html

When you create indexes (where the data goes) you define at that time how many replicas you want (they'll be distributed around the cluster)

Use @media query CSS, basically we just release a project where we had an enormous image of a tree on desktop at the side but not showing in table/mobile screens. So prevent image from loading its quite easy

Here is a small snippet:

.tree {
    background: none top left no-repeat; 
}

@media only screen and (min-width: 1200px) {
    .tree {
        background: url(enormous-tree.png) top left no-repeat;
    }
}

You can use the same CSS to show and hide with display/visibility/opacity but image was still loading, this was the most fail safe code we came up with.

They are lists because you type them as lists in the dictionary:

bikes = {
    # Bike designed for children"
    "Trike": ["Trike", 20, 100],
    # Bike designed for everyone"
    "Kruzer": ["Kruzer", 50, 165]
    }

You should use the bike-class instead:

bikes = {
    # Bike designed for children"
    "Trike": Bike("Trike", 20, 100),
    # Bike designed for everyone"
    "Kruzer": Bike("Kruzer", 50, 165)
    }

This will allow you to get the cost of the bikes with bike.cost as you were trying to.

for bike in bikes.values():
    profit = bike.cost * margin
    print(bike.name + " : " + str(profit))

This will now print:

Kruzer : 33.0
Trike : 20.0

For those who are using Oracle 12.1.0 for development purposes:
I found that the above methods would have no effect on the db user: "system", because the account_status would remain in the expired-grace period.

The easiest solution was for me to use SQL Developer:
within SQL Developer, I had to go to: View / DBA / Security and then Users / System and then on the right side: Actions / Expire pw and then: Actions / Edit and I could untick the option for expired.

This cleared the account_status, it shows OPEN again, and the SQL Developer is no longer showing the ORA-28002 message.

In very simple terms (because the other answers are referring you to all the official design patterns anyway, so look at them for further details):

If you want to have a class which is monitored by other classes in the ecosystem of your program you say that you want the class to be observable. I.e. there might be some changes in its state which you would want to broadcast to the rest of the program.

Now, to do this we have to call some kind of method. We don't want the Observable class to be tightly coupled with the classes that are interested in observing it. It doesn't care who it is as long as it fulfils certain criteria. (Imagine it is a radio station, it doesn't care who is listening as long as they have an FM radio tuned on their frequency). To achieve that we use an interface, referred to as the Observer.

Therefore, the Observable class will have a list of Observers (i.e. instances implementing the Observer interface methods you might have). Whenever it wants to broadcast something, it just calls the method on all the observers, one after the other.

The last thing to close the puzzle is how will the Observable class know who is interested? So the Observable class must offer some mechanism to allow Observers to register their interest. A method such as addObserver(Observer o) internally adds the Observer to the list of observers, so that when something important happens, it loops through the list and calls the respective notification method of the Observer interface of each instance in the list.

It might be that in the interview they did not ask you explicitly about the java.util.Observer and java.util.Observable but about the generic concept. The concept is a design pattern, which Java happens to provide support for directly out of the box to help you implement it quickly when you need it. So I would suggest that you understand the concept rather than the actual methods/classes (which you can look up when you need them).

UPDATE

In response to your comment, the actual java.util.Observable class offers the following facilities:

1. Maintaining a list of java.util.Observer instances. New instances interested in being notified can be added through addObserver(Observer o), and removed through deleteObserver(Observer o).

2. Maintaining an internal state, specifying whether the object has changed since the last notification to the observers. This is useful because it separates the part where you say that the Observable has changed, from the part where you notify the changes. (E.g. Its useful if you have multiple changes happening and you only want to notify at the end of the process rather than at each small step). This is done through setChanged(). So you just call it when you changed something to the Observable and you want the rest of the Observers to eventually know about it.

3. Notifying all observers that the specific Observable has changed state. This is done through notifyObservers(). This checks if the object has actually changed (i.e. a call to setChanged() was made) before proceeding with the notification. There are 2 versions, one with no arguments and one with an Object argument, in case you want to pass some extra information with the notification. Internally what happens is that it just iterates through the list of Observer instances and calls the update(Observable o, Object arg) method for each of them. This tells the Observer which was the Observable object that changed (you could be observing more than one), and the extra Object arg to potentially carry some extra information (passed through notifyObservers().

Here is a little more fun. I've found that very often NumPy does exactly what I wish it would do - sometimes it's faster for me to just try things than it is to read the docs. Actually a mixture of both is best.

I think your answer is fine (and it's OK to accept it if you like). This is just "extra".

import numpy as np

a = np.arange(4,10).reshape(2,3)

wh = np.where(a>7)
gt = a>7
x  = np.where(gt)

print "wh: ", wh
print "gt: ", gt
print "x:  ", x

gives:

wh:  (array([1, 1]), array([1, 2]))
gt:  [[False False False]
      [False  True  True]]
x:   (array([1, 1]), array([1, 2]))

... but:

print "a[wh]: ", a[wh]
print "a[gt]  ", a[gt]
print "a[x]:  ", a[x]

gives:

a[wh]:  [8 9]
a[gt]   [8 9]
a[x]:   [8 9]

In Mercurial you use hg log --keyword to search for keywords in the commit messages and hg log --user to search for a particular user. See hg help log for other ways to limit the log.

PHP has a built in function called json_decode(). Just pass the JSON string into this function and it will convert it to the PHP equivalent string, array or object.

In order to pass it as a string from Javascript, you can convert it to JSON using

JSON.stringify(object);

or a library such as Prototype

C - an older programming language that is described as Hands-on. As the programmer you must tell the program to do everything. Also this language will let you do almost anything. It does not support object orriented code. Thus no classes.

C++ - an extention language per se of C. In C code ++ means increment 1. Thus C++ is better than C. It allows for highly controlled object orriented code. Once again a very hands on language that goes into MUCH detail.

C# - Full object orriented code resembling the style of C/C++ code. This is really closer to JAVA. C# is the latest version of the C style languages and is very good for developing web applications.

Use the exact layout numbers described here and a nice blogpost here.

so:

layout := "2006-01-02T15:04:05.000Z"
str := "2014-11-12T11:45:26.371Z"
t, err := time.Parse(layout, str)

if err != nil {
    fmt.Println(err)
}
fmt.Println(t)

gives:

>> 2014-11-12 11:45:26.371 +0000 UTC

I know. Mind boggling. Also caught me first time. Go just doesn't use an abstract syntax for datetime components (YYYY-MM-DD), but these exact numbers (I think the time of the first commit of go Nope, according to this. Does anyone know?).

You can use boolean indexing:

df = pd.DataFrame({'Sales':[10,20,30,40,50], 'A':[3,4,7,6,1]})
print (df)
   A  Sales
0  3     10
1  4     20
2  7     30
3  6     40
4  1     50

s = 30

df1 = df[df['Sales'] >= s]
print (df1)
   A  Sales
2  7     30
3  6     40
4  1     50

df2 = df[df['Sales'] < s]
print (df2)
   A  Sales
0  3     10
1  4     20

It's also possible to invert mask by ~:

mask = df['Sales'] >= s
df1 = df[mask]
df2 = df[~mask]
print (df1)
   A  Sales
2  7     30
3  6     40
4  1     50

print (df2)
   A  Sales
0  3     10
1  4     20

print (mask)
0    False
1    False
2     True
3     True
4     True
Name: Sales, dtype: bool

print (~mask)
0     True
1     True
2    False
3    False
4    False
Name: Sales, dtype: bool

The year() function just retrieves the year component of the underlying Date object, so it returns a number.

Calling format('YYYY') will invoke moment's string formatting functions, which will parse the format string supplied, and build a new string containing the appropriate data. Since you only are passing YYYY, then the result will be a string containing the year.

If all you need is the year, then use the year() function. It will be faster, as there is less work to do.

Do note that while years are the same in this regard, months are not! Calling format('M') will return months in the range 1-12. Calling month() will return months in the range 0-11. This is due to the same behavior of the underlying Date object.

I like to use the program Artistic Style. According to their website:

Artistic Style is a source code indenter, formatter, and beautifier for the C, C++, C# and Java programming languages.

It runs in Window, Linux and Mac. It will do things like indenting, replacing tabs with spaces or vice-versa, putting spaces around operations however you like (converting if(x<2) to if ( x<2 ) if that's how you like it), putting braces on the same line as function definitions, or moving them to the line below, etc. All the options are controlled by command line parameters.

In order to use it in vim, just set the formatprg option to it, and then use the gq command. So, for example, I have in my .vimrc:

autocmd BufNewFile,BufRead *.cpp set formatprg=astyle\ -T4pb

so that whenever I open a .cpp file, formatprg is set with the options I like. Then, I can type gg to go to the top of the file, and gqG to format the entire file according to my standards. If I only need to reformat a single function, I can go to the top of the function, then type gq][ and it will reformat just that function.

The options I have for astyle, -T4pb, are just my preferences. You can look through their docs, and change the options to have it format the code however you like.

Here's a demo. Before astyle:

int main(){if(x<2){x=3;}}

float test()
{
if(x<2)
x=3;
}

After astyle (gggqG):

int main()
{
    if (x < 2)
    {
        x = 3;
    }
}

float test()
{
    if (x < 2)
        x = 3;
}

Hope that helps.

If you use the InnoDB storage engine for (some of) your MySQL tables, you’ve probably already came across a problem with its default configuration. As you may have noticed in your MySQL’s data directory (in Debian/Ubuntu – /var/lib/mysql) lies a file called ‘ibdata1'. It holds almost all the InnoDB data (it’s not a transaction log) of the MySQL instance and could get quite big. By default this file has a initial size of 10Mb and it automatically extends. Unfortunately, by design InnoDB data files cannot be shrinked. That’s why DELETEs, TRUNCATEs, DROPs, etc. will not reclaim the space used by the file.

I think you can find good explanation and solution there :

http://vdachev.net/2007/02/22/mysql-reducing-ibdata1/

After Saving $data->save(). all data is pushed inside $data. As this is an object and the current row is just saved recently inside $data. so last insertId will be found inside $data->id.

Response code will be:

return Response::json(array('success' => true, 'last_insert_id' => $data->id), 200);

I had the same problem with Celery. My setting.py before:

SECRET_KEY = os.environ.get('DJANGO_SECRET_KEY')

after:

SECRET_KEY = os.environ.get('DJANGO_SECRET_KEY', <YOUR developing key>)

If the environment variables are not defined then: SECRET_KEY = YOUR developing key

This seems to work fine:

<button onclick="location.href='mailto:[email protected]';">send mail</button>

you can try this

import docx

def getText(filename):
    doc = docx.Document(filename)
    fullText = []
    for para in doc.paragraphs:
        fullText.append(para.text)
    return '\n'.join(fullText)

You can specify an empty string as an argument to join, if no argument is specified a comma is used.

 arr.join('');

Use the action ACTION_DIAL in your intent, this way you won't need any permission. The reason you need the permission with ACTION_CALL is to make a phone call without any action from the user.

Intent intent = new Intent(Intent.ACTION_DIAL);
intent.setData(Uri.parse("tel:0987654321"));
startActivity(intent);

Use android:divider="#FF0000" and android:dividerHeight="2px" for ListView.

<ListView 
android:id="@android:id/list"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:divider="#0099FF"
android:dividerHeight="2px"/>

There's no Console.writeline in Java. Its in .NET.

Console and standard out are not same. If you read the Javadoc page you mentioned, you will see that an application can have access to a console only if it is invoked from the command line and the output is not redirected like this

java -jar MyApp.jar > MyApp.log

Other such cases are covered in SimonJ's answer, though he missed out on the point that there's no Console.writeline.

In Android, change application id in

Textarea resize control is available via the CSS3 resize property:

textarea { resize: both; } /* none|horizontal|vertical|both */
textarea.resize-vertical{ resize: vertical; }
textarea.resize-none { resize: none; }

Allowable values self-explanatory: none (disables textarea resizing), both, vertical and horizontal.

Notice that in Chrome, Firefox and Safari the default is both.

If you want to constrain the width and height of the textarea element, that's not a problem: these browsers also respect max-height, max-width, min-height, and min-width CSS properties to provide resizing within certain proportions.

Code example:

#textarea-wrapper {_x000D_
  padding: 10px;_x000D_
  background-color: #f4f4f4;_x000D_
  width: 300px;_x000D_
}_x000D_
_x000D_
#textarea-wrapper textarea {_x000D_
  min-height:50px;_x000D_
  max-height:120px;_x000D_
  width: 290px;_x000D_
}_x000D_
_x000D_
#textarea-wrapper textarea.vertical { _x000D_
  resize: vertical;_x000D_
}

<div id="textarea-wrapper">_x000D_
  <label for="resize-default">Textarea (default):</label>_x000D_
  <textarea name="resize-default" id="resize-default"></textarea>_x000D_
  _x000D_
  <label for="resize-vertical">Textarea (vertical):</label>_x000D_
  <textarea name="resize-vertical" id="resize-vertical" class="vertical">Notice this allows only vertical resize!</textarea>_x000D_
</div>

I know this is an old post, but the issue still seems to surface under different server environments. None of the above were the solution for me. In my case it came down to web optimization and making use gzip, or rather needing to disable it for videos.

I added this to my htaccess file and it took care it. SetEnvIfNoCase Request_URI .(?:ogv|ogg|oga|m4v|mp4|m4a|mov|mp3|wav|webma?|webmv)$ no-gzip dont-vary

I was already using these attributes on my tag: controls playsinline

Use CSS:

<html>
<head>
<style>
.Large
{
    font-size: 16pt;
    height: 50px;
}
</style>
<body>
<input type="text" class="Large">
</body>
</html>

What I can do to fix this (other than installing a real SSL certificate).

You can't.

On an https webpage you can only make AJAX request to https webpage (With a certificate trusted by the browser, if you use a self-signed one, it will not work for your visitors)

An other regex-based solution:

>>> strs = "foo\tbar\t\tspam"

>>> r = re.compile(r'([^\t]*)\t*')
>>> r.findall(strs)[:-1]
['foo', 'bar', 'spam']

If you can use Java NIO (JDK 1.4 or greater), then I think you're looking for java.nio.channels.FileChannel.lock()

Eclipse uses it's own internal compiler that can compile to several Java versions.

From Eclipse Help > Java development user guide > Concepts > Java Builder

The Java builder builds Java programs using its own compiler (the Eclipse Compiler for Java) that implements the Java Language Specification.

For Eclipse Mars.1 Release (4.5.1), this can target 1.3 to 1.8 inclusive.

When you configure a project:

[project-name] > Properties > Java Compiler > Compiler compliance level

This configures the Eclipse Java compiler to compile code to the specified Java version, typically 1.8 today.

Host environment variables, eg JAVA_HOME etc, are not used.

The Oracle/Sun JDK compiler is not used.

To add a WHERE clause inside an INSERT statement simply;

INSERT INTO table_name (column1,column2,column3)
SELECT column1, column2, column3 FROM  table_name
WHERE column1 = 'some_value'

I know this question is 5 years old, but for anybody wondering how to do this without re-rendering the main page. This solution uses the dart editor/scripting language.

You could have an <object> tag that contains a data attribute. Make the <object> 1px by 1px and then use something like dart to dynamically change the <object>'s data attribute which re-renders the data in the 1px by 1px object.

HTML Script:

<object id="external_source" type="text/html" data="" width="1px" height="1px">
</object>

<button id="button1" type="button">Start Script</button>

<script async type="application/dart" src="dartScript.dart"></script>
<script async src="packages/browser/dart.js"></script>

someScript.php:

<?php
echo 'hello world';
?>

dartScript.dart:

import 'dart:html';

InputElement button1;
ObjectElement externalSource;

void main() {
    button1 = querySelector('#button1')
        ..onClick.listen(runExternalSource);

    externalSource = querySelector('#external_source');
}

void runExternalSource(Event e) {
    externalSource.setAttribute('data', 'someScript.php');
}

So long as you aren't posting any information and you are just looking to run a script, this should work just fine.

Just build the dart script using "pub Build(generate JS)" and then upload the package onto your server.

Use mvn -X or mvn --debug to find out from which different locations Maven reads settings.xml. This switch activates debug logging. Just check the first lines of mvn --debug | findstr /i /c:using /c:reading.

Right, Maven uses the Java system property user.home as location for the .m2 folder.

But user.home does not always resolve to %USERPROFILE%\.m2. If you have moved the location of your Desktop folder to another place, user.home might resolve to the parent directory of this new Desktop folder. This happens when using Windows Vista or a more recent Windows together with Java 7 or any older Java version.

The blog post Java’s “user.home” is Wrong on Windows describes it very well and gives links to the official bug reports. The bug is marked as resolved in Java 8. The comment of the blog's visitor Lars proposes a nice workaround.

Yes, you missed the form encapsulation:

JSFiddle

<form>
   <input id="tbQuestion" type="text" placeholder="Post a question?" required/>
   <input id="btnSubmit" type="submit" />
</form>

As others have said, the only correct answer is no, the type has been erased.

If the list has a non-zero number of elements, you could investigate the type of the first element ( using it's getClass method, for instance ). That won't tell you the generic type of the list, but it would be reasonable to assume that the generic type was some superclass of the types in the list.

I wouldn't advocate the approach, but in a bind it might be useful.

One of the main reason for this error is due to permission not granted to all users. so remove this error, follow the following steps :
1) Go to the C:/Programme Files/Apache Software Foundation/Tomcat 7.0
2) Right click on the Tomcat 7.0 folder and click on properties.
3) go to Security Tab.
4) Select the User and click on Edit... button
5) Grant all the permission to the user and click on apply and ok.
Refresh the system and now try. I hope it will work

Based on the method Bootstrap uses to set its Responsive breakpoints, the following function returns xs, sm, md, lg or xl based on the screen width:

console.log(breakpoint());

function breakpoint() {
    let breakpoints = {
        '(min-width: 1200px)': 'xl',
        '(min-width: 992px) and (max-width: 1199.98px)': 'lg',
        '(min-width: 768px) and (max-width: 991.98px)': 'md',
        '(min-width: 576px) and (max-width: 767.98px)': 'sm',
        '(max-width: 575.98px)': 'xs',
    }

    for (let media in breakpoints) {
        if (window.matchMedia(media).matches) {
            return breakpoints[media];
        }
    }

    return null;
}

You can do this in many way.

1. Using display: flex

#block_container {_x000D_
    display: flex;_x000D_
    justify-content: center;_x000D_
}

<div id="block_container">_x000D_
  <div id="bloc1">Copyright &copy; All Rights Reserved.</div>_x000D_
  <div id="bloc2"><img src="..."></div>_x000D_
</div>

2. Using display: inline-block

#block_container {_x000D_
    text-align: center;_x000D_
}_x000D_
#block_container > div {_x000D_
    display: inline-block;_x000D_
    vertical-align: middle;_x000D_
}

<div id="block_container">_x000D_
  <div id="bloc1">Copyright &copy; All Rights Reserved.</div>_x000D_
  <div id="bloc2"><img src="..."></div>_x000D_
</div>

3. using table

<div>_x000D_
    <table align="center">_x000D_
        <tr>_x000D_
            <td>_x000D_
                <div id="bloc1">Copyright &copy; All Rights Reserved.</div>_x000D_
            </td>_x000D_
            <td>_x000D_
                <div id="bloc2"><img src="..."></div>_x000D_
            </td>_x000D_
        </tr>_x000D_
    </table>_x000D_
</div>

Remove focus but remain focusable:

editText.setFocusableInTouchMode(false);
editText.setFocusable(false);
editText.setFocusableInTouchMode(true);
editText.setFocusable(true);

EditText will lose focus, but can gain it again on a new touch event.

Using numba module for speed up.

On big datasets (500k >) pd.cut can be quite slow for binning data.

I wrote my own function in numba with just in time compilation, which is roughly 16x faster:

from numba import njit

@njit
def cut(arr):
    bins = np.empty(arr.shape[0])
    for idx, x in enumerate(arr):
        if (x >= 0) & (x < 1):
            bins[idx] = 1
        elif (x >= 1) & (x < 5):
            bins[idx] = 2
        elif (x >= 5) & (x < 10):
            bins[idx] = 3
        elif (x >= 10) & (x < 25):
            bins[idx] = 4
        elif (x >= 25) & (x < 50):
            bins[idx] = 5
        elif (x >= 50) & (x < 100):
            bins[idx] = 6
        else:
            bins[idx] = 7

    return bins

cut(df['percentage'].to_numpy())

# array([5., 5., 7., 5.])

Optional: you can also map it to bins as strings:

a = cut(df['percentage'].to_numpy())

conversion_dict = {1: 'bin1',
                   2: 'bin2',
                   3: 'bin3',
                   4: 'bin4',
                   5: 'bin5',
                   6: 'bin6',
                   7: 'bin7'}

bins = list(map(conversion_dict.get, a))

# ['bin5', 'bin5', 'bin7', 'bin5']

Speed comparison:

# create dataframe of 8 million rows for testing
dfbig = pd.concat([df]*2000000, ignore_index=True)

dfbig.shape

# (8000000, 1)

%%timeit
cut(dfbig['percentage'].to_numpy())

# 38 ms ± 616 µs per loop (mean ± std. dev. of 7 runs, 10 loops each)

%%timeit
bins = [0, 1, 5, 10, 25, 50, 100]
labels = [1,2,3,4,5,6]
pd.cut(dfbig['percentage'], bins=bins, labels=labels)

# 215 ms ± 9.76 ms per loop (mean ± std. dev. of 7 runs, 10 loops each)

In Angular 8 we can do like this:

import { Injectable } from '@angular/core';
import { YourModel} from '../models/<yourModel>.model';
import { UserService } from './user.service';
import { Observable, of } from 'rxjs';
import { map, catchError } from 'rxjs/operators';
import { HttpClient } from '@angular/common/http';

@Injectable({
  providedIn: 'root'
})

export class GlobalDataService {

  private me: <YourModel>;

  private meObservable: Observable<User>;

  constructor(private yourModalService: <yourModalService>, private http: HttpClient) {

  }

  ngOnInit() {

  }


  getYourModel(): Observable<YourModel> {

    if (this.me) {
      return of(this.me);
    } else if (this.meObservable) {
      return this.meObservable;
    }
    else {
      this.meObservable = this.yourModalService.getCall<yourModel>() // Your http call
      .pipe(
        map(data => {
          this.me = data;
          return data;
        })
      );
      return this.meObservable;
    }
  }
}

You can call it like this:

this.globalDataService.getYourModel().subscribe(yourModel => {


});

The above code will cache the result of remote API at first call so that it can be used on further requests to that method.

You have 2 ways of doing it:

• You can create a table (or multiple tables linked together) with a field for each key of your array, and insert into each field the corresponding value of your array. This is the most common way
• You can just have a table with one field and put in here your array serialized. I do not recommend you do do that, but it is useful if you don't want a complex database schema.

You add the .ico in your resource as bobobobo said and then in your main dialog's constructor you modify:

m_hIcon = AfxGetApp()->LoadIcon(ICON_ID_FROM_RESOURCE.H);

You can do by maintaining the state as below:

$('#user_button').on('click',function(){
    if($(this).attr('data-click-state') == 1) {
        $(this).attr('data-click-state', 0);
        $(this).css('background-color', 'red')
      }
    else {
      $(this).attr('data-click-state', 1);
      $(this).css('background-color', 'orange')
    }
  });

Take a reference from hear codepen example

try this

<html>
  <head>
  <script type="text/javascript">
  function validate() {
  if(myform.fname.value.length==0)
  {
   document.getElementById("error").innerHTML="this is invalid name ";
   document.myform.fname.value="";
   document.myform.fname.focus();
  }
  }
  </script>
  </head>
  <body>
  <form name="myform">
  First_Name
  <input type="text" id="fname" name="fname" onblur="validate()"> </input>
<span style="color:red;" id="error" > </span>
  <br> <br>
  Last_Name
  <input type="text" id="lname" name="lname" onblur="validate()"> </input>

  <br>
  <input type=button value=check> 

  </form>
  </body>
</html>

To fetch only current date excluding time stamp:

in lower versions, looks like hive CURRENT_DATE is not available, hence you can use (it worked for me on Hive 0.14)

select TO_DATE(FROM_UNIXTIME(UNIX_TIMESTAMP()));

In higher versions say hive 2.0, you can use :

select CURRENT_DATE;

To really get this clear, here's my for-beginners answer: You inputed the arguments in the wrong order.
A keyword argument has this style:

nullable=True, unique=False

A fixed parameter should be defined: True, False, etc. A non-keyword argument is different:

name="Ricardo", fruit="chontaduro" 

This syntax error asks you to first put name="Ricardo" and all of its kind (non-keyword) before those like nullable=True.

The necessary method is Mockito#verify:

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

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

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

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

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

So in your case the correct syntax will be:

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

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

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

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

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

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

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

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

Excel 2010 saves an UTF-16/UCS-2 TSV file, if you select File > Save As > Unicode Text (.txt). It's (force) suffixed ".txt", which you can change to ".tsv".

If you need CSV, you can then convert the TSV file in a text editor like Notepad++, Ultra Edit, Crimson Editor etc, replacing tabs by semi-colons, commas or the like. Note that e.g. for reading into a DB table, often TSV works fine already (and it is often easier to read manually).

If you need a different code page like UTF-8, use one of the above mentioned editors for converting.

with express it's so easy. all what you need is to use the consolidate module on node so you need to install it :

npm install consolidate --save

then you should change the default engine to html template by this:

app.set('view engine', 'html');

register the underscore template engine for the html extension:

app.engine('html', require('consolidate').underscore);

it's done !

Now for load for example an template called 'index.html':

res.render('index', { title : 'my first page'});

maybe you will need to install the underscore module.

npm install underscore --save

I hope this helped you!

I have just copied and moved a Magento site to a local area so I could work on it offline and had the same problem.

But in the end I found out Magento was forcing a redirect from http to https and I didn't have a SSL setup. So this solved my problem http://www.magentocommerce.com/wiki/recover/ssl_access_with_phpmyadmin

It pretty much says set web/secure/use_in_adminhtml value from 1 to 0 in the core_config_data to allow non-secure access to the admin area

I have created this JQuery function

/**
 * Draw a table from json array
 * @param {array} json_data_array Data array as JSON multi dimension array
 * @param {array} head_array Table Headings as an array (Array items must me correspond to JSON array)
 * @param {array} item_array JSON array's sub element list as an array
 * @param {string} destinaion_element '#id' or '.class': html output will be rendered to this element
 * @returns {string} HTML output will be rendered to 'destinaion_element'
 */

function draw_a_table_from_json(json_data_array, head_array, item_array, destinaion_element) {
    var table = '<table>';
    //TH Loop
    table += '<tr>';
    $.each(head_array, function (head_array_key, head_array_value) {
        table += '<th>' + head_array_value + '</th>';
    });
    table += '</tr>';
    //TR loop
    $.each(json_data_array, function (key, value) {

        table += '<tr>';
        //TD loop
        $.each(item_array, function (item_key, item_value) {
            table += '<td>' + value[item_value] + '</td>';
        });
        table += '</tr>';
    });
    table += '</table>';

    $(destinaion_element).append(table);
}
;

A new answer that uses dplyr and tidyr:

Extracts the desired column names and converts to a list

library(tidyverse)

col_names <- raw_dta %>% 
  slice(2) %>%
  pivot_longer(
    cols = "X2":"X10", # until last named column
    names_to = "old_names",
    values_to = "new_names") %>% 
  pull(new_names)

Removes the incorrect rows and adds the correct column names

dta <- raw_dta %>% 
  slice(-1, -2) %>% # Removes the rows containing new and original names
  set_names(., nm = col_names)

This one worked, double quotes when $user and $password are outside single quotes. Single quotes when inside a single quote statement.

mysql --user="$user" --password="$password" --database="$user" --execute='DROP DATABASE '$user'; CREATE DATABASE '$user';'
