This is a very old question, but I think that a new answer might add some value since, in my opinion, no one directly addressed some of the concerns in the OP.

Despite what the accepted answer suggests, list objects in R are not hash maps. If you want to make a parallel with python, list are more like, you guess, python lists (or tuples actually).

It's better to describe how most R objects are stored internally (the C type of an R object is SEXP). They are made basically of three parts:

• an header, which declares the R type of the object, the length and some other meta data;
• the data part, which is a standard C heap-allocated array (contiguous block of memory);
• the attributes, which are a named linked list of pointers to other R objects (or NULL if the object doesn't have attributes).

From an internal point of view, there is little difference between a list and a numeric vector for instance. The values they store are just different. Let's break two objects into the paradigm we described before:

x <- runif(10)
y <- list(runif(10), runif(3))

For x:

• The header will say that the type is numeric (REALSXP in the C-side), the length is 10 and other stuff.
• The data part will be an array containing 10 double values.
• The attributes are NULL, since the object doesn't have any.

For y:

• The header will say that the type is list (VECSXP in the C-side), the length is 2 and other stuff.
• The data part will be an array containing 2 pointers to two SEXP types, pointing to the value obtained by runif(10) and runif(3) respectively.
• The attributes are NULL, as for x.

So the only difference between a numeric vector and a list is that the numeric data part is made of double values, while for the list the data part is an array of pointers to other R objects.

What happens with names? Well, names are just some of the attributes you can assign to an object. Let's see the object below:

z <- list(a=1:3, b=LETTERS)

• The header will say that the type is list (VECSXP in the C-side), the length is 2 and other stuff.
• The data part will be an array containing 2 pointers to two SEXP types, pointing to the value obtained by 1:3 and LETTERS respectively.
• The attributes are now present and are a names component which is a character R object with value c("a","b").

From the R level, you can retrieve the attributes of an object with the attributes function.

The key-value typical of an hash map in R is just an illusion. When you say:

z[["a"]]

this is what happens:

• the [[ subset function is called;
• the argument of the function ("a") is of type character, so the method is instructed to search such value from the names attribute (if present) of the object z;
• if the names attribute isn't there, NULL is returned;
• if present, the "a" value is searched in it. If "a" is not a name of the object, NULL is returned;
• if present, the position of the first occurence is determined (1 in the example). So the first element of the list is returned, i.e. the equivalent of z[[1]].

The key-value search is rather indirect and is always positional. Also, useful to keep in mind:

• in hash maps the only limit a key must have is that it must be hashable. names in R must be strings (character vectors);

• in hash maps you cannot have two identical keys. In R, you can assign names to an object with repeated values. For instance:

    names(y) <- c("same", "same")
  

is perfectly valid in R. When you try y[["same"]] the first value is retrieved. You should know why at this point.

In conclusion, the ability to give arbitrary attributes to an object gives you the appearance of something different from an external point of view. But R lists are not hash maps in any way.

Actually Abstract Data Types is:

• Concepts or theoretical model that defines a data type logically
• Specifies set of data and set of operations that can be performed on that data
• Does not mention anything about how operations will be implemented
• "Existing as an idea but not having a physical idea"

For example, lets see specifications of some Abstract Data Types,

1. List Abstract Data Type: initialize(), get(), insert(), remove(), etc.
2. Stack Abstract Data Type: push(), pop(), peek(), isEmpty(), isNull(), etc.
3. Queue Abstract Data Type: enqueue(), dequeue(), size(), peek(), etc.

This works for me:

convert original.png -fuzz 10% -transparent white transparent.png

where the smaller the fuzz %, the closer to true white or conversely, the larger the %, the more variation from white is allowed to become transparent

Try typing this into the Node command-line environment:

.load c:/users/laura/desktop/nodeTest.js.

It should work for what you're trying to do.

If you want to call the file directly, you'd have to have it in the root directory where your Node installation resides.

You can probably skip the step of explicitly creating an array...

One trick that I like to use is to set the inter-field separator (IFS) to the delimiter character. This is especially handy for iterating through the space or return delimited results from the stdout of any of a number of unix commands.

Below is an example using semicolons (as you had mentioned in your question):

export IFS=";"
sentence="one;two;three"
for word in $sentence; do
  echo "$word"
done

Note: in regular Bourne-shell scripting setting and exporting the IFS would occur on two separate lines (IFS='x'; export IFS;).

I agree with Mike's answer but there's an implicit 3 second wait if no elements are found which can be switched on/off which is useful if you're performing this action a lot:

driver.manage().timeouts().implicitlyWait(0, TimeUnit.MILLISECONDS);
boolean exists = driver.findElements( By.id("...") ).size() != 0
driver.manage().timeouts().implicitlyWait(3, TimeUnit.SECONDS);

Putting that into a utility method should improve performance if you're running a lot of tests

Just to demonstrate the changes that editor.renderWhitespace : none||boundary||all will do to your VSCode I added this screenshot:
.

Where Tab are ? and Spaceare .

In case you need both max and min from same table:

    select * from (
(select city, length(city) as maxlen from station
order by maxlen desc limit 1)
union
(select city, length(city) as minlen from station
order by minlen,city limit 1))a;

The approach that I am giving is the fastest pagination that SQL server can achieve. I have tested this on 5 million records. This approach is far better than "OFFSET 10 ROWS FETCH NEXT 10 ROWS ONLY" provided by SQL Server.

-- The below given code computes the page numbers and the max row of previous page
-- Replace <<>> with the correct table data.
-- Eg. <<IdentityColumn of Table>> can be EmployeeId and <<Table>> will be dbo.Employees

DECLARE @PageNumber int=1; --1st/2nd/nth page. In stored proc take this as input param.
DECLARE @NoOfRecordsPerPage int=1000;

 DECLARE @PageDetails TABLE
       (
        <<IdentityColumn of Table>> int,
        rownum int,
        [PageNumber] int
       )           
       INSERT INTO @PageDetails values(0, 0, 0)
       ;WITH CTE AS
       (
       SELECT <<IdentityColumn of Table>>, ROW_NUMBER() OVER(ORDER BY <<IdentityColumn of Table>>) rownum FROM <<Table>>
       )
       Insert into @PageDetails 
       SELECT <<IdentityColumn of Table>>, CTE.rownum, ROW_NUMBER() OVER (ORDER BY rownum) as [PageNumber] FROM CTE WHERE CTE.rownum%@NoOfRecordsPerPage=0


--SELECT * FROM @PageDetails 

-- Actual pagination
SELECT TOP (@NoOfRecordsPerPage)
FROM <<Table>> AS <<Table>>
WHERE <<IdentityColumn of Table>> > (SELECT <<IdentityColumn of Table>> FROM 
@PageDetails WHERE PageNumber=@PageNumber)
ORDER BY <<Identity Column of Table>>

There are multiple ways to calculate the distance based on the coordinates i.e latitude and longitude

Install and import

from geopy import distance
from math import sin, cos, sqrt, atan2, radians
from sklearn.neighbors import DistanceMetric
import osrm
import numpy as np

Define coordinates

lat1, lon1, lat2, lon2, R = 20.9467,72.9520, 21.1702, 72.8311, 6373.0
coordinates_from = [lat1, lon1]
coordinates_to = [lat2, lon2]

Using haversine

dlon = radians(lon2) - radians(lon1)
dlat = radians(lat2) - radians(lat1)
    
a = sin(dlat / 2)**2 + cos(lat1) * cos(lat2) * sin(dlon / 2)**2
c = 2 * atan2(sqrt(a), sqrt(1 - a))
    
distance_haversine_formula = R * c
print('distance using haversine formula: ', distance_haversine_formula)

Using haversine with sklearn

dist = DistanceMetric.get_metric('haversine')
    
X = [[radians(lat1), radians(lon1)], [radians(lat2), radians(lon2)]]
distance_sklearn = R * dist.pairwise(X)
print('distance using sklearn: ', np.array(distance_sklearn).item(1))

Using OSRM

osrm_client = osrm.Client(host='http://router.project-osrm.org')
coordinates_osrm = [[lon1, lat1], [lon2, lat2]] # note that order is lon, lat
    
osrm_response = osrm_client.route(coordinates=coordinates_osrm, overview=osrm.overview.full)
dist_osrm = osrm_response.get('routes')[0].get('distance')/1000 # in km
print('distance using OSRM: ', dist_osrm)

Using geopy

distance_geopy = distance.distance(coordinates_from, coordinates_to).km
print('distance using geopy: ', distance_geopy)
    
distance_geopy_great_circle = distance.great_circle(coordinates_from, coordinates_to).km 
print('distance using geopy great circle: ', distance_geopy_great_circle)

Output

distance using haversine formula:  26.07547017310917
distance using sklearn:  27.847882224769783
distance using OSRM:  33.091699999999996
distance using geopy:  27.7528030550408
distance using geopy great circle:  27.839182219511834

Printing EULA from Wix3.0 and later

1) When you compile your wix source code, the light.exe must reference the WixUIExtension.dll in command line. Use the command line switch -ext for this.

2) If when you add the reference to the WixUIExtension.dll, your project fails to compile, this is most likely because of clashes of Dialog IDs, i.e. your project was using the same IDs of dialogs as some standard dialogs in WixUIExtension.dll, give different IDs to your dialogs. This is quite common problem.

3) Your license dialog must have ScrollableText control with the id "LicenseText". Wix searches for exactly this name of control when it prints.

<Control Id="LicenseText" Type="ScrollableText" X="20" Y="60" Width="330" Height="160" Sunken="yes" TabSkip="no">
    <Text SourceFile="License.rtf" />
</Control>

and a PushButton which refers to the custom action

<Control Type="PushButton" Id="PrintButton" Width="57" Height="17" X="19" Y="244" Text="Print">
    <Publish Event="DoAction" Value="PrintEula">1</Publish>
</Control>

4) Define CustomAction with the Id="PrintEula" like this:

<CustomAction Id="PrintEula" BinaryKey="WixUIWixca" DllEntry="PrintEula" Return="ignore" Execute="immediate" />

Note: BinaryKey is different in Wix3.0 comparing to Wix2.0 and must be exactly "WixUIWixca" (case sensitive).

When user presses the button he/she will be presented with the standard Select Printer Dialog and will be able to print from there.

Having /A without additional parameters other than the filename didn't work for me, but the following code worked fine with /n

string sfile = @".\help\delta-pqca-400-100-300-fc4-user-manual.pdf";
Process myProcess = new Process();
myProcess.StartInfo.FileName = "AcroRd32.exe"; 
myProcess.StartInfo.Arguments = " /n " + "\"" + sfile + "\"";
myProcess.Start();

I was referencing a mapped drive and I found that the mapped drives are not always available to the user account that is running the scheduled task so I used \\IPADDRESS instead of MAPDRIVELETTER: and I am up and running.

Just adding for who might need.. Don't forget to alter the table!

ALTER TABLE table_name ADD FULLTEXT(column_name);

(It's been a while since I did this stuff. Please don't blindly assume that all the details below are correct. But I hope I'm not too embarrassingly wrong. :))

As the previous answer stated, the Minecraft client (as of 1.3.1) supports SRV record lookup using the service name _minecraft and the protocol name _tcp, which means that if your zone file looks like this...

arboristal.com.                 86400 IN A   <your IP address>
_minecraft._tcp.arboristal.com. 86400 IN SRV 10 20 25565 arboristal.com.
_minecraft._tcp.arboristal.com. 86400 IN SRV 10 40 25566 arboristal.com.
_minecraft._tcp.arboristal.com. 86400 IN SRV 10 40 25567 arboristal.com.

...then Minecraft clients who perform SRV record lookup as hinted in the changelog will use ports 25566 and 25567 with preference (40% of the time each) over port 25565 (20% of the time). We can assume that Minecraft clients who do not find and respect these SRV records will use port 25565 as usual.

However, I would argue that it would actually be more "clean and professional" to do it using a load balancer such as Nginx. (I pick Nginx just because I've used it before. I'm not claiming it's uniquely suited to this task. It might even be a bad choice for some reason.) Then you don't have to mess with your DNS, and you can use the same approach to load-balance any service, not just ones like Minecraft which happen to have done the hard client-side work to look up and respect SRV records. To do it the Nginx way, you'd run Nginx on the arboristal.com machine with something like the following in /etc/nginx/sites-enabled/arboristal.com:

upstream minecraft_servers {
    ip_hash;
    server 127.0.0.1:25566 weight=1;
    server 127.0.0.1:25567 weight=1;
    server 127.0.0.1:25568 weight=1;
}
server {
    listen 25565;
    proxy_pass minecraft_servers;
}

Here we are controlling the load-balancing ourselves on the server side (via Nginx), so we no longer need to worry that badly behaved clients might prefer port 25565 to the other two ports. In fact, now all clients will talk to arboristal.com:25565! But the listener on that port is no longer a Minecraft server; it's Nginx, secretly proxying all the traffic onto three other ports on the same machine.

We load-balance based on a hash of the client's IP address (ip_hash), so that if a client disconnects and then reconnects later, there's a good chance that it'll get reconnected to the same Minecraft server it had before. (I don't know how much this matters to Minecraft, or how SRV-enabled clients are programmed to deal with this aspect.)

Notice that we used to run a Minecraft server on port 25565; I've moved it to port 25568 so that we can use port 25565 for the load-balancer.

A possible disadvantage of the Nginx method is that it makes Nginx a bottleneck in your system. If Nginx goes down, then all three servers become unreachable. If some part of your system can't keep up with the volume of traffic on that single port, 25565, all three servers become flaky. And not to mention, Nginx is a big new dependency in your ecosystem. Maybe you don't want to introduce yet another massive piece of software with a complicated config language and a huge attack surface. I can respect that.

A possible advantage of the Nginx method is... that it makes Nginx a bottleneck in your system! You can apply global policies via Nginx, such as rejecting packets above a certain size, or responding with a static web page to HTTP connections on port 80. You can also firewall off ports 25566, 25567, and 25568 from the Internet, since now they should be talked to only by Nginx over the loopback interface. This reduces your attack surface somewhat.

Nginx also makes it easier to add new Minecraft servers to your backend; now you can just add a server line to your config and service nginx reload. Using the old port-based approach, you'd have to add a new SRV record with your DNS provider (and it could take up to 86400 seconds for clients to notice the change) and then also remember to edit your firewall (e.g. /etc/iptables.rules) to permit external traffic over that new port.

Nginx also frees you from having to think about DNS TTLs when making ops changes. Suppose you decide to split up your three Minecraft servers onto three different physical machines with different IP addresses. Using Nginx, you can do that completely via config changes to your server lines, and you can keep those new machines inside your firewall (connected only to Nginx over a private interface), and the changes will take effect immediately, by definition. Whereas, using SRV records, you'll have to rewrite your zone file to something like this...

arboristal.com.                 86400 IN CNAME mc1.arboristal.com.
mc1.arboristal.com.             86400 IN A   <a new machine's IP address>
mc2.arboristal.com.             86400 IN A   <a new machine's IP address>
mc3.arboristal.com.             86400 IN A   <a new machine's IP address>
_minecraft._tcp.arboristal.com. 86400 IN SRV 10 20 25565 mc1.arboristal.com.
_minecraft._tcp.arboristal.com. 86400 IN SRV 10 40 25565 mc2.arboristal.com.
_minecraft._tcp.arboristal.com. 86400 IN SRV 10 40 25565 mc3.arboristal.com.

...and you'll have to leave all three new machines poking outside your firewall so that they can receive connections from the Internet. And you'll have to wait up to 86400 seconds for your clients to notice the change, which could affect the complexity of your rollout plan. And if you were running any other services (such as an HTTP server) on arboristal.com, now you have to move them to the mc1.arboristal.com machine because of how I did that CNAME. I did that only for the benefit of those hypothetical Minecraft clients who don't respect SRV records and will still be trying to connect to arboristal.com:25565.

So, I think both ways (SRV records and Nginx load-balancing) are reasonable, and your choice will depend on your personal preferences. I caricature the options as:

• SRV records: "I just need it to work. I don't want complexity. And I know and trust my DNS provider."
• Nginx: "I foresee arboristal.com taking over the world, or at least moving to a bigger machine someday. I'm not scared of learning a new tool. What's a zone file?"

there you go

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

echo $tomorrow;

this will output

04-16-2013

Found this on OzGrid courtesy of Mr. Aaron Blood - simple direct and works.

Code:
Cells(1, 3).Copy Cells(1, 1)
Cells(1, 1).Value = Cells(1, 3).Value

However, I kinda suspect you were just providing us with an oversimplified example to ask the question. If you just want to copy formats from one range to another it looks like this...

Code:
Cells(1, 3).Copy
    Cells(1, 1).PasteSpecial (xlPasteFormats)
    Application.CutCopyMode = False

You can do something like that:

$ci = get_instance(); // CI_Loader instance
$ci->load->config('email');
echo $ci->config->item('name');

As per your question requirement , I would like to suggest that Map will solve your problem very efficient and without any hassle.

In Map you can give the name as key and your original object as value.

  Map<String,Cave> myMap=new HashMap<String,Cave>();

I created an attached property based on Aviad's Answer which doesn't require creating a new class

public static class RadioButtonHelper
{
    [AttachedPropertyBrowsableForType(typeof(RadioButton))]
    public static object GetRadioValue(DependencyObject obj) => obj.GetValue(RadioValueProperty);
    public static void SetRadioValue(DependencyObject obj, object value) => obj.SetValue(RadioValueProperty, value);
    public static readonly DependencyProperty RadioValueProperty =
        DependencyProperty.RegisterAttached("RadioValue", typeof(object), typeof(RadioButtonHelper), new PropertyMetadata(new PropertyChangedCallback(OnRadioValueChanged)));

    private static void OnRadioValueChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        if (d is RadioButton rb)
        {
            rb.Checked -= OnChecked;
            rb.Checked += OnChecked;
        }
    }

    public static void OnChecked(object sender, RoutedEventArgs e)
    {
        if (sender is RadioButton rb)
        {
            rb.SetCurrentValue(RadioBindingProperty, rb.GetValue(RadioValueProperty));
        }
    }

    [AttachedPropertyBrowsableForType(typeof(RadioButton))]
    public static object GetRadioBinding(DependencyObject obj) => obj.GetValue(RadioBindingProperty);
    public static void SetRadioBinding(DependencyObject obj, object value) => obj.SetValue(RadioBindingProperty, value);

    public static readonly DependencyProperty RadioBindingProperty =
        DependencyProperty.RegisterAttached("RadioBinding", typeof(object), typeof(RadioButtonHelper), new FrameworkPropertyMetadata(null, FrameworkPropertyMetadataOptions.BindsTwoWayByDefault, new PropertyChangedCallback(OnRadioBindingChanged)));

    private static void OnRadioBindingChanged(DependencyObject d, DependencyPropertyChangedEventArgs e)
    {
        if (d is RadioButton rb && rb.GetValue(RadioValueProperty).Equals(e.NewValue))
        {
            rb.SetCurrentValue(RadioButton.IsCheckedProperty, true);
        }
    }
}

usage :

<RadioButton GroupName="grp1" Content="Value 1"
    helpers:RadioButtonHelper.RadioValue="val1" helpers:RadioButtonHelper.RadioBinding="{Binding SelectedValue}"/>
<RadioButton GroupName="grp1" Content="Value 2"
    helpers:RadioButtonHelper.RadioValue="val2" helpers:RadioButtonHelper.RadioBinding="{Binding SelectedValue}"/>
<RadioButton GroupName="grp1" Content="Value 3"
    helpers:RadioButtonHelper.RadioValue="val3" helpers:RadioButtonHelper.RadioBinding="{Binding SelectedValue}"/>
<RadioButton GroupName="grp1" Content="Value 4"
    helpers:RadioButtonHelper.RadioValue="val4" helpers:RadioButtonHelper.RadioBinding="{Binding SelectedValue}"/>

I do it with recursive ctes, but i'm not sure if it is the best way

declare @initial as int = 1000;
declare @final as int =1050;

with cte_n as (
    select @initial as contador
    union all
    select contador+1 from cte_n 
    where contador <@final
) select * from cte_n option (maxrecursion 0)

You have to include the jquery framework in your document head from a cdn for example:

<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>

Then you have to include a own script for example:

(function( $ ) {

  $(document).ready(function(){
      $('input').click(function() {
          $(this).css('background-color', 'green');
      }
  });


  $(window).load(function() { 
  });

})( jQuery );

This part is a mapping of the $ to jQuery, so actually it is jQuery('selector').function();

(function( $ ) {

})( jQuery );

Here you can find die api of jquery where all functions are listed with examples and explanation: http://api.jquery.com/

and to delete a lot of folders, you could also create a batch file with the command spdenne posted.

1) make a text file that has the following contents replacing the folder names in quotes with your folder names:

rmdir /s /q "My Apps"  
rmdir /s /q "My Documents"  
rmdir /s /q "My Pictures"  
rmdir /s /q "My Work Files"

2) save the batch file with a .bat extension (for example deletefiles.bat)
3) open a command prompt (Start > Run > Cmd) and execute the batch file. you can do this like so from the command prompt (substituting X for your drive letter):

X:  
deletefiles.bat

In JavaScript, most functions are both callable and instantiable: they have both a [[Call]] and [[Construct]] internal methods.

As callable objects, you can use parentheses to call them, optionally passing some arguments. As a result of the call, the function can return a value.

var player = makeGamePlayer("John Smith", 15, 3);

The code above calls function makeGamePlayer and stores the returned value in the variable player. In this case, you may want to define the function like this:

function makeGamePlayer(name, totalScore, gamesPlayed) {
  // Define desired object
  var obj = {
    name:  name,
    totalScore: totalScore,
    gamesPlayed: gamesPlayed
  };
  // Return it
  return obj;
}

Additionally, when you call a function you are also passing an additional argument under the hood, which determines the value of this inside the function. In the case above, since makeGamePlayer is not called as a method, the this value will be the global object in sloppy mode, or undefined in strict mode.

As constructors, you can use the new operator to instantiate them. This operator uses the [[Construct]] internal method (only available in constructors), which does something like this:

1. Creates a new object which inherits from the .prototype of the constructor
2. Calls the constructor passing this object as the this value
3. It returns the value returned by the constructor if it's an object, or the object created at step 1 otherwise.

var player = new GamePlayer("John Smith", 15, 3);

The code above creates an instance of GamePlayer and stores the returned value in the variable player. In this case, you may want to define the function like this:

function GamePlayer(name,totalScore,gamesPlayed) {
  // `this` is the instance which is currently being created
  this.name =  name;
  this.totalScore = totalScore;
  this.gamesPlayed = gamesPlayed;
  // No need to return, but you can use `return this;` if you want
}

By convention, constructor names begin with an uppercase letter.

The advantage of using constructors is that the instances inherit from GamePlayer.prototype. Then, you can define properties there and make them available in all instances

If your app is written in TypeScript, try

(global as any).logger = // ...

or

Object.assign(global, { logger: // ... })

However, I will do it only when React Native's __DEV__ in testing environment.

When using a wildcard, it had to be present on both sides of the refspec, so +refs/heads/*:refs/heads/master will not work. But you can use +HEAD:refs/heads/master:

git config remote.heroku.push +HEAD:refs/heads/master

Also, you can do this directly with git push:

git push heroku +HEAD:master
git push -f heroku HEAD:master

I can't speak to what you are trying to do specifically with the function itself, but if you don't like the regex being built every time, here are two solutions and some caveats about each.

Here is one way to do this:

function makeSortString(s) {
  if(!makeSortString.translate_re) makeSortString.translate_re = /[öäüÖÄÜ]/g;
  var translate = {
    "ä": "a", "ö": "o", "ü": "u",
    "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
  };
  return ( s.replace(makeSortString.translate_re, function(match) { 
    return translate[match]; 
  }) );
}

This will obviously make the regex a property of the function itself. The only thing you may not like about this (or you may, I guess it depends) is that the regex can now be modified outside of the function's body. So, someone could do this to modify the interally-used regex:

makeSortString.translate_re = /[a-z]/g;

So, there is that option.

One way to get a closure, and thus prevent someone from modifying the regex, would be to define this as an anonymous function assignment like this:

var makeSortString = (function() {
  var translate_re = /[öäüÖÄÜ]/g;
  return function(s) {
    var translate = {
      "ä": "a", "ö": "o", "ü": "u",
      "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
    };
    return ( s.replace(translate_re, function(match) { 
      return translate[match]; 
    }) );
  }
})();

Hopefully this is useful to you.

UPDATE: It's early and I don't know why I didn't see the obvious before, but it might also be useful to put you translate object in a closure as well:

var makeSortString = (function() {
  var translate_re = /[öäüÖÄÜ]/g;
  var translate = {
    "ä": "a", "ö": "o", "ü": "u",
    "Ä": "A", "Ö": "O", "Ü": "U"   // probably more to come
  };
  return function(s) {
    return ( s.replace(translate_re, function(match) { 
      return translate[match]; 
    }) );
  }
})();

You could also disable the cascade delete convention in global scope of your application by doing this:

modelBuilder.Conventions.Remove<OneToManyCascadeDeleteConvention>()
modelBuilder.Conventions.Remove<ManyToManyCascadeDeleteConvention>()

you just need to give focus to the next input field (by invoking focus()method on that input element), for example if you're using jQuery this code will simulate the tab key when enter is pressed:

var inputs = $(':input').keypress(function(e){ 
    if (e.which == 13) {
       e.preventDefault();
       var nextInput = inputs.get(inputs.index(this) + 1);
       if (nextInput) {
          nextInput.focus();
       }
    }
});

If speed is important, use this:

/**
 * Replace last occurrence of a string with another string
 * x - the initial string
 * y - string to replace
 * z - string that will replace
 */
function replaceLast(x, y, z){
    var a = x.split("");
    var length = y.length;
    if(x.lastIndexOf(y) != -1) {
        for(var i = x.lastIndexOf(y); i < x.lastIndexOf(y) + length; i++) {
            if(i == x.lastIndexOf(y)) {
                a[i] = z;
            }
            else {
                delete a[i];
            }
        }
    }

    return a.join("");
}

It's faster than using RegExp.

If you have several fields in your table and your table is huge, it's better DO NOT USE * because of it load all fields to memory and using the following will have better performance

SELECT COUNT(1) FROM fooTable;

I would use VARCHAR for variable length data, but not with fixed length data. Because a SHA-1 value is always 160 bit long, the VARCHAR would just waste an additional byte for the length of the fixed-length field.

And I also wouldn’t store the value the SHA1 is returning. Because it uses just 4 bit per character and thus would need 160/4 = 40 characters. But if you use 8 bit per character, you would only need a 160/8 = 20 character long field.

So I recommend you to use BINARY(20) and the UNHEX function to convert the SHA1 value to binary.

I compared storage requirements for BINARY(20) and CHAR(40).

CREATE TABLE `binary` (
    `id` int unsigned auto_increment primary key,
    `password` binary(20) not null
);
CREATE TABLE `char` (
    `id` int unsigned auto_increment primary key,
    `password` char(40) not null
);

With million of records binary(20) takes 44.56M, while char(40) takes 64.57M. InnoDB engine.

In my case I changed the datetime field in the SQL database to not allow null. SqlDataReader then allowed me to cast the value directly to a DateTime.

You can use coalesce(column_name,0) instead of just column_name. The coalesce function returns the first non-NULL value in the list.

I should mention that per-row functions like this are usually problematic for scalability. If you think your database may get to be a decent size, it's often better to use extra columns and triggers to move the cost from the select to the insert/update.

This amortises the cost assuming your database is read more often than written (and most of them are).

To use support libraries starting from version 26.0.0 you need to add Google's Maven repository to your project's build.gradle file as described here: https://developer.android.com/topic/libraries/support-library/setup.html

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

For Android Studio 3.0.0 and above:

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

you don't - not like this. give an id to your tag , lets say it looks like this now :

<h3 id="myHeader"></h3>

then set the value like that :

myHeader.innerText = "public offers";

Response.Write is used to display the text not for executing JavaScript, If you want to execute the JavaScript from your code than try as below:

try
{
    con.Open();
    string pass="abc";
    cmd = new SqlCommand("insert into register values('" + txtName.Text + "','" + txtEmail.Text + "','" + txtPhoneNumber.Text + "','" + ddlUserType.SelectedText + "','" + pass + "')", con);
    cmd.ExecuteNonQuery();
    con.Close();
    Page.ClientScript.RegisterStartupScript(this.GetType(), "click","alert('Login Successful');");
}
catch (Exception ex)
{
}
finally
{
    con.Close();
}

I'm using this to redirect with React Router v4:

this.props.history.push('/foo');

Hope it work for you ;)

2012 This is a better solution for this scenario (tested With Visual Studio 2008):

Configuration config = WebConfigurationManager.OpenWebConfiguration(HttpContext.Current.Request.ApplicationPath);
config.AppSettings.Settings.Remove("MyVariable");
config.AppSettings.Settings.Add("MyVariable", "MyValue");
config.Save();

Update 2018 =>
Tested in vs 2015 - Asp.net MVC5

var config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
config.AppSettings.Settings["MyVariable"].Value = "MyValue";
config.Save();

if u need to checking element exist, use this code:

var config = System.Web.Configuration.WebConfigurationManager.OpenWebConfiguration("~");
if (config.AppSettings.Settings["MyVariable"] != null)
{
config.AppSettings.Settings["MyVariable"].Value = "MyValue";
}
else { config.AppSettings.Settings.Add("MyVariable", "MyValue"); }
config.Save();

Well, this may not be the most elegant solution (semantically), but in some cases it'll work without any drawbacks: Instead of padding, use a transparent border on the parent element. The absolute positioned child elements will honor the border and it'll be rendered exactly the same (except you're using the border of the parent element for styling).

A different approach.
On the figure() call specify properties or modify the figure handle properties after h = figure().

This creates a full screen figure based on normalized units.
figure('units','normalized','outerposition',[0 0 1 1])

The units property can be adjusted to inches, centimeters, pixels, etc.

See figure documentation.

If you don't care about IE =6, you could use pure CSS ...

.forum:hover { background-color: #380606; }

.forum { color: white; }_x000D_
.forum:hover { background-color: #380606 !important; }_x000D_
/* we use !important here to override specificity. see http://stackoverflow.com/q/5805040/ */_x000D_
_x000D_
#blue { background-color: blue; }

<meta charset=utf-8>_x000D_
_x000D_
<p class="forum" style="background-color:red;">Red</p>_x000D_
<p class="forum" style="background:green;">Green</p>_x000D_
<p class="forum" id="blue">Blue</p>

With jQuery, usually it is better to create a specific class for this style:

.forum_hover { background-color: #380606; }

and then apply the class on mouseover, and remove it on mouseout.

$('.forum').hover(function(){$(this).toggleClass('forum_hover');});

$(document).ready(function(){_x000D_
  $('.forum').hover(function(){$(this).toggleClass('forum_hover');});_x000D_
});

.forum_hover { background-color: #380606 !important; }_x000D_
_x000D_
.forum { color: white; }_x000D_
#blue { background-color: blue; }

<p class="forum" style="background:green;">Green</p>_x000D_
<p class="forum" id="blue">Blue</p>

If you must not modify the class, you could save the original background color in .data():

  $('.forum').data('bgcolor', '#380606').hover(function(){
    var $this = $(this);
    var newBgc = $this.data('bgcolor');
    $this.data('bgcolor', $this.css('background-color')).css('background-color', newBgc);
  });

$(document).ready(function(){_x000D_
  $('.forum').data('bgcolor', '#380606').hover(function(){_x000D_
    var $this = $(this);_x000D_
    var newBgc = $this.data('bgcolor');_x000D_
    $this.data('bgcolor', $this.css('background-color')).css('background-color', newBgc);_x000D_
  });_x000D_
});

.forum { color: white; }_x000D_
#blue { background-color: blue; }

or

  $('.forum').hover(

      var $this = $(this);
      $this.data('bgcolor', $this.css('background-color')).css('background-color', '#380606');

You can submit the regex to preg_match which will return false if the regex is not valid. Don't forget to use the @ to suppress error messages:

@preg_match($regexToTest, '');

• Will return 1 if the regex is //.
• Will return 0 if the regex is okay.
• Will return false otherwise.

Wow! Mean this that you must learn a different programming language just to send two keys to the keyboard? There are simpler ways for you to achieve the same thing. :-)

The Batch file below is an example that start another program (cmd.exe in this case), send a command to it and then send an Up Arrow key, that cause to recover the last executed command. The Batch file is simple enough to be understand with no problems, so you may modify it to fit your needs.

@if (@CodeSection == @Batch) @then


@echo off

rem Use %SendKeys% to send keys to the keyboard buffer
set SendKeys=CScript //nologo //E:JScript "%~F0"

rem Start the other program in the same Window
start "" /B cmd

%SendKeys% "echo off{ENTER}"

set /P "=Wait and send a command: " < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "echo Hello, world!{ENTER}"

set /P "=Wait and send an Up Arrow key: [" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{UP}"

set /P "=] Wait and send an Enter key:" < NUL
ping -n 5 -w 1 127.0.0.1 > NUL
%SendKeys% "{ENTER}"

%SendKeys% "exit{ENTER}"

goto :EOF


@end


// JScript section

var WshShell = WScript.CreateObject("WScript.Shell");
WshShell.SendKeys(WScript.Arguments(0));

For a list of key names for SendKeys, see: http://msdn.microsoft.com/en-us/library/8c6yea83(v=vs.84).aspx

For example:

LEFT ARROW    {LEFT}
RIGHT ARROW   {RIGHT}

The question is LeetCode #148, and there are plenty of solutions offered in all major languages. Mine is as follows, but I'm wondering about the time complexity. In order to find the middle element, we traverse the complete list each time. First time n elements are iterated over, second time 2 * n/2 elements are iterated over, so on and so forth. It seems to be O(n^2) time.

def sort(linked_list: LinkedList[int]) -> LinkedList[int]:
    # Return n // 2 element
    def middle(head: LinkedList[int]) -> LinkedList[int]:
        if not head or not head.next:
            return head
        slow = head
        fast = head.next

        while fast and fast.next:
            slow = slow.next
            fast = fast.next.next

        return slow

    def merge(head1: LinkedList[int], head2: LinkedList[int]) -> LinkedList[int]:
        p1 = head1
        p2 = head2
        prev = head = None

        while p1 and p2:
            smaller = p1 if p1.val < p2.val else p2
            if not head:
                head = smaller
            if prev:
                prev.next = smaller
            prev = smaller

            if smaller == p1:
                p1 = p1.next
            else:
                p2 = p2.next

        if prev:
            prev.next = p1 or p2
        else:
            head = p1 or p2

        return head

    def merge_sort(head: LinkedList[int]) -> LinkedList[int]:
        if head and head.next:
            mid = middle(head)
            mid_next = mid.next
            # Makes it easier to stop
            mid.next = None

            return merge(merge_sort(head), merge_sort(mid_next))
        else:
            return head

    return merge_sort(linked_list)

Avoid the Date object creation w/ System.currentTimeMillis(). A divide by 1000 gets you to Unix epoch.

As mentioned in a comment, you typically want a primitive long (lower-case-l long) not a boxed object long (capital-L Long) for the unixTime variable's type.

long unixTime = System.currentTimeMillis() / 1000L;

you can also covert int to str first and assign index to it then again convert it to int like this:

int(str(x)[n]) //where x is an integer value

With MySQL if you are inserting into a table that has a auto increment primary key and you want to use a built-in MySQL function such as NOW() then you can do something like this:

INSERT INTO course_payment 
SELECT NULL, order_id, payment_gateway, total_amt, charge_amt, refund_amt, NOW()
FROM orders ORDER BY order_id DESC LIMIT 10;

Pitching in with a websocket solution...

function ping(ip, isUp, isDown) {
  var ws = new WebSocket("ws://" + ip);
  ws.onerror = function(e){
    isUp();
    ws = null;
  };
  setTimeout(function() { 
    if(ws != null) {
      ws.close();
      ws = null;
      isDown();
    }
  },2000);
}

You close the second Scanner which closes the underlying InputStream, therefore the first Scanner can no longer read from the same InputStream and a NoSuchElementException results.

The solution: For console apps, use a single Scanner to read from System.in.

Aside: As stated already, be aware that Scanner#nextInt does not consume newline characters. Ensure that these are consumed before attempting to call nextLine again by using Scanner#newLine().

See: Do not create multiple buffered wrappers on a single InputStream

Try this way:

<%= f.select(:object_field, ['Item 1', ...], {}, { :class => 'my_style_class' }) %>

select helper takes two options hashes, one for select, and the second for html options. So all you need is to give default empty options as first param after list of items and then add your class to html_options.

http://api.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#method-i-select

./config --prefix=/usr --openssldir=/usr/local/openssl shared

Try this config line instead to overwrite the default. It installs to prefix /usr/local/ssl by default in your setup when you leave off the prefix. You probably have "/usr/local/ssl/bin/openssl" instead of overwriting /usr/bin/openssl. You can also use /usr/local for prefix instead, but you would need to adjust your path accordingly if that is not already on your path. Here is the INSTALL documentation:

  $ ./config
  $ make
  $ make test
  $ make install

 [If any of these steps fails, see section Installation in Detail below.]

This will build and install OpenSSL in the default location, which is (for
historical reasons) /usr/local/ssl. If you want to install it anywhere else,
run config like this:

  $ ./config --prefix=/usr/local --openssldir=/usr/local/openssl

Simple Example to understand how to access elements in the dictionary:-

Create a Dictionary

d = {'dog' : 'bark', 'cat' : 'meow' } 
print(d.get('cat'))
print(d.get('lion'))
print(d.get('lion', 'Not in the dictionary'))
print(d.get('lion', 'NA'))
print(d.get('dog', 'NA'))

Here are some main key differences between constructor and method in java

1. Constructors are called at the time of object creation automatically. But methods are not called during the time of object creation automatically.
2. Constructor name must be same as the class name. Method has no such protocol.
3. The constructors can’t have any return type. Not even void. But methods can have a return type and also void. Click to know details - Difference between constructor and method in Java

Another option is using msmtp.

What you need is to set up your .msmtprc with something like this (example is using gmail):

account default
host smtp.gmail.com
port 587
from [email protected]
tls on
tls_starttls on
tls_trust_file ~/.certs/equifax.pem
auth on
user [email protected]
password <password>
logfile ~/.msmtp.log

Then just call:

(echo "Subject: <subject>"; echo; echo "<message>") | msmtp <[email protected]>

in your script

Update: For HTML mail you have to put the headers as well, so you might want to make a file like this:

From: [email protected]
To: [email protected]
Subject: Important message
Mime-Version: 1.0
Content-Type: text/html

<h1>Mail body will be here</h1>
The mail body <b>should</b> start after one blank line from the header.

And mail it like

cat email-template | msmtp [email protected]

The same can be done via command line as well, but it might be easier using a file.

A solution without reference to a Bean:

<h:button value="login" 
        outcome="content/configuration.xhtml?i=1" />

In my project I needed this approach:

<h:commandButton value="login" 
        action="content/configuration.xhtml?faces-redirect=true&amp;i=1"  />

The trick is pretty simple... The request cycle is still pretty much alive. You can just add a new variable that will create a temporary, calling

app.get('some/url/endpoint', middleware1, middleware2);

Since you can handle your request in the first middleware

(req, res, next) => {
    var yourvalue = anyvalue
}

In middleware 1 you handle your logic and store your value like below:

req.anyvariable = yourvalue

In middleware 2 you can catch this value from middleware 1 doing the following:

(req, res, next) => {
    var storedvalue = req.yourvalue
}

If I use exit() in a code and run it in the shell, it shows a message asking whether I want to kill the program or not. It's really disturbing. See here

But sys.exit() is better in this case. It closes the program and doesn't create any dialogue box.

I made an alias for doing this and works like a charm, I do this:

 git config --global alias.mergetest '!f(){ git merge --no-commit --no-ff "$1"; git merge --abort; echo "Merge aborted"; };f '

Now I just call

git mergetest <branchname>

Multi joins in SQL work by progressively creating derived tables one after the other. See this link explaining the process:

https://www.interfacett.com/blogs/multiple-joins-work-just-like-single-joins/

One workaround might be to write a simple batch file to run the program then shutdown the computer.

You can shut down from the command line -- so your script could be fairly simple:

c:\directory\myProgram.exe
C:\WINDOWS\system32\shutdown.exe -s -f -t 0

You can use the Get-InstalledModule

If (-not(Get-InstalledModule SomeModule -ErrorAction silentlycontinue)) {
  Write-Host "Module does not exist"
}
Else {
  Write-Host "Module exists"
}

A char can hold a single character only, a character literal is a single character in single quote, i.e. '&' - if you have more characters than one you want to use a string, for that you have to use double quotes:

case "&&": 

where F13 is the cell you need to reference:

=CELL("Row",F13)  yields 13; its row number

=CELL("Col",F13)  yields 6; its column number;  

=SUBSTITUTE(ADDRESS(1,COLUMN(F13)*1,4),"1","") yields F; its column letter

note you can only do this with Numbers and Strings

you could do...

var a, b, c; a = b = c = 0; //but why?

c++;
// c = 1, b = 0, a = 0;

You should check this MSDN article and download the .docx file and read it carefully , it was very helpful for me.

There are four types of integers based on size:

• short integer: 2 byte
• long integer: 4 byte
• long long integer: 8 byte
• integer: depends upon the compiler (16 bit, 32 bit, or 64 bit)

Using some ES6:

Get the options first, filter the value based on the option and set the selected attribute to true.

window.onload = () => {_x000D_
_x000D_
  Array.from(document.querySelector(`#Mobility`).options)_x000D_
    .filter(x => x.value === "12")[0]_x000D_
    .setAttribute('selected', true);_x000D_
_x000D_
};

<select style="width: 280px" id="Mobility" name="Mobility">_x000D_
  <option selected disabled>Please Select</option>_x000D_
  <option>K</option>_x000D_
  <option>1</option>_x000D_
  <option>2</option>_x000D_

Did you install flask-sqlalchemy? It looks like you have SQLAlchemy installed but not the Flask extension. Try pip install Flask-SQLAlchemy in your project's virtualenv to install it from PyPI.

Here is another solution, that has all the source available in a single, simple ZIP file.

It presents the OpenFileDialog with additional windows flags that makes it work like the Windows 7+ Folder Selection dialog.

Per the website, it is public domain: "There’s no license as such as you are free to take and do with the code what you will."

ln /home/jake/doc/test/2000/something /home/jake/xxx

More information: man ln

/home/jake/xxx is like a new directory. To avoid "is not a directory: No such file or directory" error, as @trlkly comment, use relative path in the target, that is, using the example:

1. cd /home/jake/
2. ln -s /home/jake/doc/test/2000/something xxx

I found the answer. IE stores passwords in two different locations based on the password type:

• Http-Auth: %APPDATA%\Microsoft\Credentials, in encrypted files
• Form-based: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2, encrypted with the url

From a very good page on NirSoft.com:

Starting from version 7.0 of Internet Explorer, Microsoft completely changed the way that passwords are saved. In previous versions (4.0 - 6.0), all passwords were saved in a special location in the Registry known as the "Protected Storage". In version 7.0 of Internet Explorer, passwords are saved in different locations, depending on the type of password. Each type of passwords has some limitations in password recovery:

• AutoComplete Passwords: These passwords are saved in the following location in the Registry: HKEY_CURRENT_USER\Software\Microsoft\Internet Explorer\IntelliForms\Storage2 The passwords are encrypted with the URL of the Web sites that asked for the passwords, and thus they can only be recovered if the URLs are stored in the history file. If you clear the history file, IE PassView won't be able to recover the passwords until you visit again the Web sites that asked for the passwords. Alternatively, you can add a list of URLs of Web sites that requires user name/password into the Web sites file (see below).

• HTTP Authentication Passwords: These passwords are stored in the Credentials file under Documents and Settings\Application Data\Microsoft\Credentials, together with login passwords of LAN computers and other passwords. Due to security limitations, IE PassView can recover these passwords only if you have administrator rights.

In my particular case it answers the question of where; and I decided that I don't want to duplicate that. I'll continue to use CredRead/CredWrite, where the user can manage their passwords from within an established UI system in Windows.

use sys module

import sys
sys.exit()

The Lambda function expects JSON input, therefore parsing the query string is needed. The solution is to change the query string to JSON using the Mapping Template.
I used it for C# .NET Core, so the expected input should be a JSON with "queryStringParameters" parameter.
Follow these 4 steps below to achieve that:

1. Open the mapping template of your API Gateway resource and add new application/json content-tyap:

2. Copy the template below, which parses the query string into JSON, and paste it into the mapping template:
   

   {
   "queryStringParameters": {#foreach($key in $input.params().querystring.keySet())#if($foreach.index > 0),#end"$key":"$input.params().querystring.get($key)"#end}
   }
   

3. In the API Gateway, call your Lambda function and add the following query string (for the example): param1=111&param2=222&param3=333

4. The mapping template should create the JSON output below, which is the input for your Lambda function.

   {
   "queryStringParameters": {"param3":"333","param1":"111","param2":"222"}
   }
   

5. You're done. From this point, your Lambda function's logic can use the query string parameters.
   Good luck!

Starting with elif option == 2:, you indented one time too many. In a decent text editor, you should be able to highlight these lines and press Shift+Tab to fix the issue.

Additionally, there is no statement after for x in range(x, 1, 1):. Insert an indented pass to do nothing in the for loop.

Also, in the first line, you wrote option == 1. == tests for equality, but you meant = ( a single equals sign), which assigns the right value to the left name, i.e.

option = 1

Tested and working!

Michael.. if its just for formatting then you can format the cell to append any value.

Just right click and select Format Cell on the context menu, select custom and then specify type as you wish... for above example it would be X0. Here 'X' is the prefix and 0 is the numeric after.

Hope this helps..

Cheers...

None of the solutions worked for me in Windows - it seems to use capital H rather than h for the file status and the grep command requires an extra caret as ^ also represents the start of line as well as negating the next character.

Windows solution

1. Open Git Bash and change to the relevant top level directory.
2. git ls-files -v | grep '^^H' to list all the uncached files
3. git ls-files -v | grep '^^H' | cut -c 3- | tr '\012' '\000' | xargs -0 git update-index --no-skip-worktree to undo the files skipping of all files that was done via update-index --skip-worktree
4. git ls-files -v | grep '^^H]' | cut -c 3- | tr '\012' '\000' | xargs -0 git update-index --no-assume-unchanged to undo the files skipping of all files that was done via update-index --assume-unchanged
5. git ls-files -v | grep '^^H' to again list all the uncached files and check whether the above commands have worked - this should now not return anything

You must convert to List as shown below:

    String[] valores = hierarquia.split(".");       
    List<String> lista =  Arrays.asList(valores);

    String jpqlQuery = "SELECT a " +
            "FROM AcessoScr a " +
            "WHERE a.scr IN :param ";

    Query query = getEntityManager().createQuery(jpqlQuery, AcessoScr.class);                   
    query.setParameter("param", lista);     
    List<AcessoScr> acessos = query.getResultList();

The following code shows initiating as well as aborting an Ajax request:

function libAjax(){
  var req;
  function start(){

  req =    $.ajax({
              url: '1.php',
              success: function(data){
                console.log(data)
              }
            });

  }

  function stop(){
    req.abort();
  }

  return {start:start,stop:stop}
}

var obj = libAjax();

 $(".go").click(function(){


  obj.start();


 })



 $(".stop").click(function(){

  obj.stop();


 })

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<input type="button" class="go" value="GO!" >
   <input type="button" class="stop" value="STOP!" >

One line in cmd:

for /F "delims= " %i in ('pip list --outdated --format=legacy') do pip install -U %i

So a

pip check

afterwards should make sure no dependencies are broken.

For the people that want a CTRL+C, CTRL-V solution, here you go:

    /**
     * Retrieves the number that was pressed on the keyboard.
     *
     * @param {Event} event The keypress event containing the keyCode.
     * @returns {number|null} a number between 0-9 that was pressed. Returns null if there was no numeric key pressed.
     */
    function getNumberFromKeyEvent(event) {
        if (event.keyCode >= 96 && event.keyCode <= 105) {
            return event.keyCode - 96;
        } else if (event.keyCode >= 48 && event.keyCode <= 57) {
            return event.keyCode - 48;
        }
        return null;
    }

It uses the logic of the first answer.

You could format the dates before you add them to your array. That is how I did. I used AngularJS

//convert the date to a standard format

var dt = new Date(date);

//take only the date and month and push them to your label array

$rootScope.charts.mainChart.labels.push(dt.getDate() + "-" + (dt.getMonth() + 1));

Use this array in your chart presentation

Try this one. You can strip just ' and " with:

$FileName = str_replace(array('\'', '"'), '', $UserInput); 

Here is another way of doing this for pyspark:

#import concat and lit functions from pyspark.sql.functions 
from pyspark.sql.functions import concat, lit

#Create your data frame
countryDF = sqlContext.createDataFrame([('Ethiopia',), ('Kenya',), ('Uganda',), ('Rwanda',)], ['East Africa'])

#Use select, concat, and lit functions to do the concatenation
personDF = countryDF.select(concat(countryDF['East Africa'], lit('n')).alias('East African'))

#Show the new data frame
personDF.show()

----------RESULT-------------------------

84
+------------+
|East African|
+------------+
|   Ethiopian|
|      Kenyan|
|     Ugandan|
|     Rwandan|
+------------+

You are getting that error because when the param1 if statements are evaluated, param is always null due to being scoped variables without delayed expansion.

When parentheses are used, all the commands and variables within those parentheses are expanded. And at that time, param1 has no value making the if statements invalid. When using delayed expansion, the variables are only expanded when the command is actually called.

Also I recommend using if not defined command to determine if a variable is set.

Short answer: minimum possible access (cf Jon Skeet's answer).

Long answer:

Non-nested types, enumeration and delegate accessibilities (may only have internal or public accessibility)

                     | Default   | Permitted declared accessibilities
------------------------------------------------------------------
namespace            | public    | none (always implicitly public)

enum                 | public    | public, internal

interface            | internal  | public, internal

class                | internal  | public, internal

struct               | internal  | public, internal

delegate             | internal  | public, internal

Nested type and member accessiblities

                     | Default   | Permitted declared accessibilities
------------------------------------------------------------------
namespace            | public    | none (always implicitly public)

enum                 | public    | All¹

interface            | public    | All¹

class                | private   | All¹

struct               | private   | public, internal, private²

delegate             | private   | All¹

constructor          | private   | All¹

enum member          | public    | none (always implicitly public)

interface member     | public    | none (always implicitly public)
     
method               | private   | All¹

field                | private   | All¹

user-defined operator| none      | public (must be declared public)

¹ All === public, protected, internal, private, protected internal

² structs cannot inherit from structs or classes (although they can, interfaces), hence protected is not a valid modifier

The accessibility of a nested type depends on its accessibility domain, which is determined by both the declared accessibility of the member and the accessibility domain of the immediately containing type. However, the accessibility domain of a nested type cannot exceed that of the containing type.

Note: CIL also has the provision for protected and internal (as opposed to the existing protected "or" internal), but to my knowledge this is not currently available for use in C#.

Along the lines of Tim Down's answer but leveraging jQuery (mentioned by the OP) and loosely coupling the containing page and the iframe, you could do the following:

In the iframe:

<script>
    $(function() {
        var w = window;
        if (w.frameElement != null
                && w.frameElement.nodeName === "IFRAME"
                && w.parent.jQuery) {
            w.parent.jQuery(w.parent.document).trigger('iframeready');
        }
    });
</script>

In the containing page:

<script>
    function myHandler() {
        alert('iframe (almost) loaded');
    }
    $(document).on('iframeready', myHandler);
</script>

The iframe fires an event on the (potentially existing) parent window's document - please beware that the parent document needs a jQuery instance of itself for this to work. Then, in the parent window you attach a handler to react to that event.

This solution has the advantage of not breaking when the containing page does not contain the expected load handler. More generally speaking, it shouldn't be the concern of the iframe to know its surrounding environment.

Please note, that we're leveraging the DOM ready event to fire the event - which should be suitable for most use cases. If it's not, simply attach the event trigger line to the window's load event like so:

$(window).on('load', function() { ... });

I also wanted similar functionality where I have a File Input Control with display:none and a Button control where I wanted to trigger click event of File Input Control when I click on the button, below is the code to do so

<input type="button" (click)="fileInput.click()" class="btn btn-primary" value="Add From File">
<input type="file" style="display:none;" #fileInput/>

as simple as that and it's working flawlessly...

Depends on which apostrophe you are talking about: there’s ', ‘, ’ and probably numerous other ones, depending on the context and the language you’re intending to write. And with a declared character encoding of e.g. UTF-8 you can also write them directly into your HTML: ', ‘, ’.

This would give the current date and time:

public String getCurrDate()
{
    String dt;
    Date cal = Calendar.getInstance().getTime();
    dt = cal.toLocaleString();
    return dt;
}

You can use .indexOf() and .substr() like this:

var val = $("input").val();
var myString = val.substr(val.indexOf("?") + 1)

You can test it out here. If you're sure of the format and there's only one question mark, you can just do this:

var myString = $("input").val().split("?").pop();

For the JS, try

data: {id: the_id}
...
success: function(data) {
        alert('the server returned ' + data;
    }

and

$the_id = intval($_POST['id']);

in PHP

Just my 2 cents regarding the divs option.

Famous/Infamous and SamsaraJS (and possibly others) use absolutely positioned non-nested divs (with non-trivial HTML/CSS content), combined with matrix2d/matrix3d for positioning and 2D/3D transformations, and achieve a stable 60FPS on moderate mobile hardware, so I'd argue against divs being a slow option.

There are plenty of screen recordings on Youtube and elsewhere, of high-performance 2D/3D stuff running in the browser with everything being an DOM element which you can Inspect Element on, at 60FPS (mixed with WebGL for certain effects, but not for the main part of the rendering).

Cause of the issue:

Arguments property in Execute Process Task available on the Control Flow tab is expecting a value of data type DT_WSTR and not DT_STR.

SSIS 2008 R2 package illustrating the issue and fix:

Create an SSIS package in Business Intelligence Development Studio (BIDS) 2008 R2 and name it as SO_13177007.dtsx. Create a package variable with the following information.

Name   Scope        Data Type  Value
------ ------------ ---------- -----
IdVar  SO_13177007  Int32      123

Drag and drop an Execute Process Task onto the Control Flow tab and name it as Pass arguments

Double-click the Execute Process Task to open the Execute Process Task Editor. Click Expressions page and then click the Ellipsis button against the Expressions property to view the Property Expression Editor.

On the Property Expression Editor, select the property Arguments and click the Ellipsis button against the property to open the Expression Builder.

On the Expression Builder, enter the following expression and click Evaluate Expression. This expression tries to convert the integer value in the variable IdVar to string data type.

(DT_STR, 10, 1252) @[User::IdVar]

Clicking Evaluate Expression will display the following error message because the Arguments property on Execute Process Task expects a value of data type DT_WSTR.

To fix the issue, update the expression as shown below to convert the integer value to data type DT_WSTR. Clicking Evaluate Expression will display the value in the Evaluated value text area.

(DT_WSTR, 10) @[User::IdVar]

References:

To understand the differences between the data types DT_STR and DT_WSTR in SSIS, read the documentation Integration Services Data Types on MSDN. Here are the quotes from the documentation about these two string data types.

DT_STR

A null-terminated ANSI/MBCS character string with a maximum length of 8000 characters. (If a column value contains additional null terminators, the string will be truncated at the occurrence of the first null.)

DT_WSTR

A null-terminated Unicode character string with a maximum length of 4000 characters. (If a column value contains additional null terminators, the string will be truncated at the occurrence of the first null.)

You can use:

input[type=text]
{
 /*Styles*/
}

Define your common style attributes inside this. and for extra style you can add a class then.

Make a truth table and use SUMPRODUCT to get the values. Copy this into cell B1 on Sheet2 and copy down as far as you need:
=SUMPRODUCT(--($A1 = Sheet1!$A:$A), Sheet1!$B:$B)
the part that creates the truth table is:
--($A1 = Sheet1!$A:$A)
This returns an array of 0's and 1's. 1 when the values match and a 0 when they don't. Then the comma after that will basically do what I call "funny" matrix multiplication and will return the result. I may have misunderstood your question though, are there duplicate values in Column A of Sheet1?

I know this was already answered as to what the actual problem is, however I want to offer a simple workaround.

I wanted to use the get_results() method however I didn't have the driver, and I'm not somewhere I can get that added. So, before I called

$stmt->bind_results($var1,$var2,$var3,$var4...etc);

I created an empty array, and then just bound the results as keys in that array:

$result = array();
$stmt->bind_results($result['var1'],$result['var2'],$result['var3'],$result['var4']...etc);

so that those results could easily be passed into methods or cast to an object for further use.

Hope this helps anyone who's looking to do something similar.

In my case, I did remove maven nature manually from .project file while having the project opened in Eclipse. So what I'd to do was to add maven nature again using the contextual menu (roght click on the project > configuration > add maven nature). Afterwards, everything worked nice :D

Can you post that cursor example or link to the question? There's probably an even better way than a recursive CTE.

In addition to other comments, cursors when used improperly (which is often) cause unnecessary page/row locks.

Try the following command, which I have tested:

$ cp -pv --parents $(git diff --name-only) DESTINATION-DIRECTORY

SET @cnt=0; 
SELECT s.* 
FROM   (SELECT ( @cnt := @cnt + 1 ) AS rank, 
               a.* 
        FROM   one AS a 
        ORDER  BY a.salary DESC) AS s 
WHERE  s.rank = '3'; 

I suppose rgba() would work here. After all, browser support for both box-shadow and rgba() is roughly the same.

/* 50% black box shadow */
box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);

div {_x000D_
    width: 200px;_x000D_
    height: 50px;_x000D_
    line-height: 50px;_x000D_
    text-align: center;_x000D_
    color: white;_x000D_
    background-color: red;_x000D_
    margin: 10px;_x000D_
}_x000D_
_x000D_
div.a {_x000D_
  box-shadow: 10px 10px 10px #000;_x000D_
}_x000D_
_x000D_
div.b {_x000D_
  box-shadow: 10px 10px 10px rgba(0, 0, 0, 0.5);_x000D_
}

<div class="a">100% black shadow</div>_x000D_
<div class="b">50% black shadow</div>

You can simply use value_counts with sort option set to False. This will preserve ordering of the categories

df['colour'].value_counts(sort=False).plot.bar(rot=0)

In real world or project we have requirement in advance and needs to create variable and methods inside the class , On the basis of requirement we needs to decide whether we needs to create

1. Local ( create n access within block or method constructor)
2. Static,
3. Instance Variable( every object has its own copy of it),

=>2. Static Keyword we will used with variable which going to same for particular class throughout for all objects, e.g in selenium : we decalre webDriver as static=> so we do not need to create webdriver again and again for every test case= Static Webdriver driver(but parallel execution it will cause problem but thats another case); then, Real world scenario=>If India is class then, flag, money would be same every indian so we might take as static. Anatoher example: utility method we always declare as static b'cos it will be used in different test cases. Static stored in CMA( PreGen space)=PreGen (Fixed memory)changed to Metaspace after Java8 as now its growing dynamically

In some cases, managed code can actually be faster than native code. For instance, "mark-and-sweep" garbage collection algorithms allow environments like the JRE or CLR to free large numbers of short-lived (usually) objects in a single pass, where most C/C++ heap objects are freed one-at-a-time.

From wikipedia:

For many practical purposes, allocation/deallocation-intensive algorithms implemented in garbage collected languages can actually be faster than their equivalents using manual heap allocation. A major reason for this is that the garbage collector allows the runtime system to amortize allocation and deallocation operations in a potentially advantageous fashion.

That said, I've written a lot of C# and a lot of C++, and I've run a lot of benchmarks. In my experience, C++ is a lot faster than C#, in two ways: (1) if you take some code that you've written in C#, port it to C++ the native code tends to be faster. How much faster? Well, it varies a whole lot, but it's not uncommon to see a 100% speed improvement. (2) In some cases, garbage collection can massively slow down a managed application. The .NET CLR does a terrible job with large heaps (say, > 2GB), and can end up spending a lot of time in GC--even in applications that have few--or even no--objects of intermediate life spans.

Of course, in most cases that I've encounted, managed languages are fast enough, by a long shot, and the maintenance and coding tradeoff for the extra performance of C++ is simply not a good one.

Java 1.7 makes our lives much easier thanks to the try-with-resources statement.

try (Connection connection = dataSource.getConnection();
    Statement statement = connection.createStatement()) {
    try (ResultSet resultSet = statement.executeQuery("some query")) {
        // Do stuff with the result set.
    }
    try (ResultSet resultSet = statement.executeQuery("some query")) {
        // Do more stuff with the second result set.
    }
}

This syntax is quite brief and elegant. And connection will indeed be closed even when the statement couldn't be created.

Sourcing runs shell commands in your current shell. When you source inside of a script like you are doing above, you are affecting the environment for that script, but when the script exits, the environment changes are undone, as they've effectively gone out of scope.

If your intent is to run shell commands in the virtualenv, you can do that in your script after sourcing the activate script. If your intent is to interact with a shell inside the virtualenv, then you can spawn a sub-shell inside your script which would inherit the environment.

Wrap the column name in brackets like so, from becomes [from].

select [from] from table;

It is also possible to use the following (useful when querying multiple tables):

select table.[from] from table;

You can enter these module class suffixes for any module to better control where it will show or be hidden.

Along with @miensol answer, let me add some details:

If you want a Java-visible empty constructor using data classes, you need to define it explicitely.

Using default values + constructor specifier is quite easy:

data class Activity(
    var updated_on: String = "",
    var tags: List<String> = emptyList(),
    var description: String = "",
    var user_id: List<Int> = emptyList(),
    var status_id: Int = -1,
    var title: String = "",
    var created_at: String = "",
    var data: HashMap<*, *> = hashMapOf<Any, Any>(),
    var id: Int = -1,
    var counts: LinkedTreeMap<*, *> = LinkedTreeMap<Any, Any>()
) {
    constructor() : this(title = "") // this constructor is an explicit
                                     // "empty" constructor, as seen by Java.
}

This means that with this trick you can now serialize/deserialize this object with the standard Java serializers (Jackson, Gson etc).

Working with predicate for pretty long time. Here is my conclusion (SWIFT)

//Customizable! (for me was just important if at least one)
request.fetchLimit = 1


//IF IS EQUAL

//1 OBJECT
request.predicate = NSPredicate(format: "name = %@", txtFieldName.text)

//ARRAY
request.predicate = NSPredicate(format: "name = %@ AND nickName = %@", argumentArray: [name, nickname])


// IF CONTAINS

//1 OBJECT
request.predicate = NSPredicate(format: "name contains[c] %@", txtFieldName.text)

//ARRAY
request.predicate = NSPredicate(format: "name contains[c] %@ AND nickName contains[c] %@", argumentArray: [name, nickname])

Doing this with POSIX is tricky:

• POSIX Sed does not support \r or \15. Even if it did, the in place option -i is not POSIX

• POSIX Awk does support \r and \15, however the -i inplace option is not POSIX

• d2u and dos2unix are not POSIX utilities, but ex is

• POSIX ex does not support \r, \15, \n or \12

To remove carriage returns:

awk 'BEGIN{RS="^$";ORS="";getline;gsub("\r","");print>ARGV[1]}' file

To add carriage returns:

awk 'BEGIN{RS="^$";ORS="";getline;gsub("\n","\r&");print>ARGV[1]}' file

You could always make a unique index, which causes MongoDB to reject a conflicting save. Consider the following done using the mongodb shell:

> db.getCollection("test").insert ({a:1, b:2, c:3})
> db.getCollection("test").find()
{ "_id" : ObjectId("50c8e35adde18a44f284e7ac"), "a" : 1, "b" : 2, "c" : 3 }
> db.getCollection("test").ensureIndex ({"a" : 1}, {unique: true})
> db.getCollection("test").insert({a:2, b:12, c:13})      # This works
> db.getCollection("test").insert({a:1, b:12, c:13})      # This fails
E11000 duplicate key error index: foo.test.$a_1  dup key: { : 1.0 }

P.S. This is just a very common solution. If your problem still exists you can try the advanced one.

As others have explained, var self = this; allows code in a closure to refer back to the parent scope.

However, it's now 2018 and ES6 is widely supported by all major web browsers. The var self = this; idiom isn't quite as essential as it once was.

It's now possible to avoid var self = this; through the use of arrow functions.

In instances where we would have used var self = this:

function test() {
    var self = this;
    this.hello = "world";
    document.getElementById("test_btn").addEventListener("click", function() {
        console.log(self.hello); // logs "world"
    });
};

We can now use an arrow function without var self = this:

function test() {
    this.hello = "world";
    document.getElementById("test_btn").addEventListener("click", () => {
        console.log(this.hello); // logs "world"
    });
};

Arrow functions do not have their own this and simply assume the enclosing scope.

There are at least three problems with putting a BOM in UTF-8 encoded files.

1. Files that hold no text are no longer empty because they always contain the BOM.
2. Files that hold text that is within the ASCII subset of UTF-8 is no longer themselves ASCII because the BOM is not ASCII, which makes some existing tools break down, and it can be impossible for users to replace such legacy tools.
3. It is not possible to concatenate several files together because each file now has a BOM at the beginning.

And, as others have mentioned, it is neither sufficient nor necessary to have a BOM to detect that something is UTF-8:

• It is not sufficient because an arbitrary byte sequence can happen to start with the exact sequence that constitutes the BOM.
• It is not necessary because you can just read the bytes as if they were UTF-8; if that succeeds, it is, by definition, valid UTF-8.

Replace button #rock With #rock

No need for additional selector scope. You're using an id which is as specific as you can be.

JsBin example: http://jsbin.com/idobar/1/edit

Just make a selector for tables inside a MyClass.

.MyClass td {border: solid 1px red;}
.MyClass table td {border: none}

(To generically apply to all inner tables, you could also do table table td.)

You've returned a pointer to a local variable. That's bad even if threads aren't involved.

The usual way to do this, when the thread that starts is the same thread that joins, would be to pass a pointer to an int, in a location managed by the caller, as the 4th parameter of pthread_create. This then becomes the (only) parameter to the thread's entry-point. You can (if you like) use the thread exit value to indicate success:

#include <pthread.h>
#include <stdio.h>

int something_worked(void) {
    /* thread operation might fail, so here's a silly example */
    void *p = malloc(10);
    free(p);
    return p ? 1 : 0;
}

void *myThread(void *result)
{
   if (something_worked()) {
       *((int*)result) = 42;
       pthread_exit(result);
   } else {
       pthread_exit(0);
   }
}

int main()
{
   pthread_t tid;
   void *status = 0;
   int result;

   pthread_create(&tid, NULL, myThread, &result);
   pthread_join(tid, &status);

   if (status != 0) {
       printf("%d\n",result);
   } else {
       printf("thread failed\n");
   }

   return 0;
}

If you absolutely have to use the thread exit value for a structure, then you'll have to dynamically allocate it (and make sure that whoever joins the thread frees it). That's not ideal, though.

Suppose you store float value in "X" and you are storing integer value in "Y".

Var Y = Int(x);

or

var myIntValue = Int(myFloatValue)

In my case it was an issue of the PHP version.

The .phar file I was using was not compatible with PHP 5.3.9. Switching interpreter to PHP 7 did fix it.

This should be faster:

DELETE * FROM table_name;

because RDBMS don't have to look where is what.

You should be fine with truncate though:

truncate table table_name

I have this error and could not solve this for two days.So the fix of error is very simple. In body ,where you connect your script, add type="text/jsx" and this`ll resolve the problem.

I would recommend looking into conditional comments and making a separate sheet for the IEs you are having problems with.

Here is the easiest solution which works for me without writing additional codes.

// To underline text in UILable
NSMutableAttributedString *text = [[NSMutableAttributedString alloc] initWithString:@"Type your text here"];
[text addAttribute:NSUnderlineStyleAttributeName value:@(NSUnderlineStyleSingle) range:NSMakeRange(0, text.length)];
lblText.attributedText = text;

//do the edit in your javascript

$('.signinform').submit(function() { 
   $(this).ajaxSubmit({ 
       type : "POST",
       //set the data type
       dataType:'json',
       url: 'index.php/user/signin', // target element(s) to be updated with server response 
       cache : false,
       //check this in Firefox browser
       success : function(response){ console.log(response); alert(response)},
       error: onFailRegistered
   });        
   return false; 
}); 


//controller function

public function signin() {
    $arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);    

   //add the header here
    header('Content-Type: application/json');
    echo json_encode( $arr );
}

You're right: String is a subset of Object. Since String is more "precise" than Object, you should cast it to use it as an argument for System.out.println().

Since this is a common piece of functionality it's a good idea to write a directive for this. In fact, someone already did that and open sourced it. I used editablespan library in one of my projects and it worked perfectly, highly recommended.

Here is a bit of code from one of my applications... Let me know if it suits your needs. You can use this if you know the file you want to use.

URL defaultImage = ClassA.class.getResource("/packageA/subPackage/image-name.png");
File imageFile = new File(defaultImage.toURI());

Hope that helps.

If you're targeting HTML5 only you can use:

<input type="text" id="firstname" placeholder="First Name:" />

For non HTML5 browsers, I would build upon Floern's answer by using jQuery and make the javascript non-obtrusive. I would also use a class to define the blurred properties.

$(document).ready(function () {

    //Set the initial blur (unless its highlighted by default)
    inputBlur($('#Comments'));

    $('#Comments').blur(function () {
        inputBlur(this);
    });
    $('#Comments').focus(function () {
        inputFocus(this);
    });

})

Functions:

function inputFocus(i) {
    if (i.value == i.defaultValue) {
        i.value = "";
        $(i).removeClass("blurredDefaultText");
    }
}
function inputBlur(i) {
    if (i.value == "" || i.value == i.defaultValue) {
        i.value = i.defaultValue;
        $(i).addClass("blurredDefaultText");
    }
}

CSS:

.blurredDefaultText {
    color:#888 !important;
}

What you first tried should work, but the HTML is not what we would expect. I added an option to handle the initial "no item selected" case:

<select ng-options="region.code as region.name for region in regions" ng-model="region">
   <option style="display:none" value="">select a region</option>
</select>
<br>selected: {{region}}

The above generates this HTML:

<select ng-options="..." ng-model="region" class="...">
   <option style="display:none" value class>select a region</option>
   <option value="0">Alabama</option>
   <option value="1">Alaska</option>
   <option value="2">American Samoa</option>
</select>

Fiddle

Even though Angular uses numeric integers for the value, the model (i.e., $scope.region) will be set to AL, AK, or AS, as desired. (The numeric value is used by Angular to lookup the correct array entry when an option is selected from the list.)

This may be confusing when first learning how Angular implements its "select" directive.

If you want to replace a simple string and you don't need the abilities of regular expressions, you can just use replace, not replaceAll.

replace replaces each matching substring but does not interpret its argument as a regular expression.

str = xpath.replace(".", "/*/");

Use Flowplayer:

<link rel="stylesheet" href="//releases.flowplayer.org/7.0.4/commercial/skin/skin.css">
    <style>

   </style>
   <script src="//code.jquery.com/jquery-1.12.4.min.js"></script>
  <script src="//releases.flowplayer.org/7.0.4/commercial/flowplayer.min.js"></script>
  <script src="//releases.flowplayer.org/hlsjs/flowplayer.hlsjs.min.js"></script> 
  <script>
  flowplayer(function (api) {
    api.on("load", function (e, api, video) {
      $("#vinfo").text(api.engine.engineName + " engine playing " + video.type);
    }); });
  </script>

<div class="flowplayer fixed-controls no-toggle no-time play-button obj"
      style="    width: 85.5%;
    height: 80%;
    margin-left: 7.2%;

      </video>   
   </div>

Different methods are available in flowplayer.org website.

The url you are referring is a query type and I see that the request object supports a method called arguments to get the query arguments. You may also want try self.request.get('def') directly to get your value from the object..

Mongo DB requires space to store it files. So you should create folder structure for Mongo DB before starting the Mongodb server/client.

for e.g. MongoDb/Dbfiles where Mongo DB is installed.

Then in cmd promt exe mongod.exe and mongo.exe for client and done.

You may use Json.Net framework to do this. Just like this :

Account account = JsonConvert.DeserializeObject<Account>(json);

My solution displays the percentage of the tarball that is currently being uncompressed and written. I use this when writing out 2GB root filesystem images. You really need a progress bar for these things. What I do is use gzip --list to get the total uncompressed size of the tarball. From that I calculate the blocking-factor needed to divide the file into 100 parts. Finally, I print a checkpoint message for each block. For a 2GB file this gives about 10MB a block. If that is too big then you can divide the BLOCKING_FACTOR by 10 or 100, but then it's harder to print pretty output in terms of a percentage.

Assuming you are using Bash then you can use the following shell function

untar_progress () 
{ 
  TARBALL=$1
  BLOCKING_FACTOR=$(gzip --list ${TARBALL} |
    perl -MPOSIX -ane '$.==2 && print ceil $F[1]/50688')
  tar --blocking-factor=${BLOCKING_FACTOR} --checkpoint=1 \
    --checkpoint-action='ttyout=Wrote %u%  \r' -zxf ${TARBALL}
}

You are debugging two or more times. so the application may run more at a time. Then only this issue will occur. You should close all debugging applications using task-manager, Then debug again.

Mysqldump isn't bad solution. Simplest way to duplicate database:

mysqldump -uusername -ppass dbname1 | mysql -uusername -ppass dbname2

Also, you can change storage engine by this way:

mysqldump -uusername -ppass dbname1 | sed 's/InnoDB/RocksDB/' | mysql -uusername -ppass dbname2

+ theme(plot.title = element_text(size=22))

Here is the full set of things you can change in element_text:

element_text(family = NULL, face = NULL, colour = NULL, size = NULL,
  hjust = NULL, vjust = NULL, angle = NULL, lineheight = NULL,
  color = NULL)

Aggregation - separable part to whole. The part has a identity of its own, separate from what it is part of. You could pick that part and move it to another object. (real world examples: wheel -> car, bloodcell -> body)

Composition - non-separable part of the whole. You cannot move the part to another object. more like a property. (real world examples: curve -> road, personality -> person, max_speed -> car, property of object -> object )

Note that a relation that is an aggregate in one design can be a composition in another. Its all about how the relation is to be used in that specific design.

dependency - sensitive to change. (amount of rain -> weather, headposition -> bodyposition)

Note: "Bloodcell" -> Blood" could be "Composition" as Blood Cells can not exist without the entity called Blood. "Blood" -> Body" could be "Aggregation" as Blood can exist without the entity called Body.

To much code, you can use it like this:

#include<array>
#include<functional>

int main()
{
    std::array<int, 10> vec = { 1,2,3,4,5,6,7,8,9 };

    std::sort(std::begin(vec), 
              std::end(vec), 
              [](int a, int b) {return a > b; });

    for (auto item : vec)
      std::cout << item << " ";

    return 0;
}

Replace "vec" with your class and that's it.

I had the error

Error: could not find function some.function

happen when doing R CMD check of a package I was making with RStudio. I found adding

exportPattern(".")

to the NAMESPACE file did the trick. As a sidenote, I had initially configured RStudio to use ROxygen to make the documentation -- and selected the configuration where ROxygen would write my NAMESPACE file for me, which kept erasing my edits. So, in my instance I unchecked NAMESPACE from the Roxygen configuration and added exportPattern(".") to NAMESPACE to solve this error.

Here is an example. Imagine that you are going to put the files and directory names (under the current folder) to an array and count its items. The script would be like;

my_array=( `ls` )
my_array_length=${#my_array[@]}
echo $my_array_length

Or, you can iterate over this array by adding the following script:

for element in "${my_array[@]}"
do
   echo "${element}"
done

Please note that this is the core concept and the input is considered to be sanitized before, i.e. removing extra characters, handling empty Strings, and etc. (which is out of the topic of this thread).

I tested Github Flavored Markdown for a while and can summarize with four rules:

1. punctuation marks will be dropped
2. leading white spaces will be dropped
3. upper case will be converted to lower
4. spaces between letters will be converted to -

For example, if your section is named this:

## 1.1 Hello World

Create a link to it this way:

[Link](#11-hello-world)

If the size of the array is known at compile time, you can use the structure size to determine the number of elements.

struct foo fooarr[10];

for(i = 0; i < sizeof(fooarr) / sizeof(struct foo); i++)
{
  do_something(fooarr[i].data);
}

If it is not known at compile time, you will need to store a size somewhere or create a special terminator value at the end of the array.

Here's a modification to mercurial's answer that uses the subquery on the decode as well, allowing the use of variables in both instances.

DECLARE
    @EncodeIn VARCHAR(100) = 'Test String In',
    @EncodeOut VARCHAR(500),
    @DecodeOut VARCHAR(200)    

SELECT @EncodeOut = 
    CAST(N'' AS XML).value(
          'xs:base64Binary(xs:hexBinary(sql:column("bin")))'
        , 'VARCHAR(MAX)'
    )
FROM (
    SELECT CAST(@EncodeIn AS VARBINARY(MAX)) AS bin
) AS bin_sql_server_temp;

PRINT @EncodeOut

SELECT @DecodeOut = 
CAST(
    CAST(N'' AS XML).value(
        'xs:base64Binary(sql:column("bin"))'
      , 'VARBINARY(MAX)'
    ) 
    AS VARCHAR(MAX)
) 
FROM (
    SELECT CAST(@EncodeOut AS VARCHAR(MAX)) AS bin
) AS bin_sql_server_temp;

PRINT @DecodeOut

Basic ViewPager Example

This answer is a simplification of the documentation, this tutorial, and the accepted answer. It's purpose is to get a working ViewPager up and running as quickly as possible. Further edits can be made after that.

XML

Add the xml layouts for the main activity and for each page (fragment). In our case we are only using one fragment layout, but if you have different layouts on the different pages then just make one for each of them.

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout
    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context="com.example.verticalviewpager.MainActivity">

    <android.support.v4.view.ViewPager
        android:id="@+id/viewpager"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

</RelativeLayout>

fragment_one.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
                android:layout_width="match_parent"
                android:layout_height="match_parent" >

    <TextView
        android:id="@+id/textview"
        android:textSize="30sp"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerInParent="true" />

</RelativeLayout>

Code

This is the code for the main activity. It includes the PagerAdapter and FragmentOne as inner classes. If these get too large or you are reusing them in other places, then you can move them to their own separate classes.

import android.support.v4.app.Fragment;
import android.support.v4.app.FragmentManager;
import android.support.v4.app.FragmentPagerAdapter;
import android.support.v4.view.ViewPager;

public class MainActivity extends AppCompatActivity {

    static final int NUMBER_OF_PAGES = 2;

    MyAdapter mAdapter;
    ViewPager mPager;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        mAdapter = new MyAdapter(getSupportFragmentManager());
        mPager = findViewById(R.id.viewpager);
        mPager.setAdapter(mAdapter);
    }

    public static class MyAdapter extends FragmentPagerAdapter {
        public MyAdapter(FragmentManager fm) {
            super(fm);
        }

        @Override
        public int getCount() {
            return NUMBER_OF_PAGES;
        }

        @Override
        public Fragment getItem(int position) {

            switch (position) {
                case 0:
                    return FragmentOne.newInstance(0, Color.WHITE);
                case 1:
                    // return a different Fragment class here
                    // if you want want a completely different layout
                    return FragmentOne.newInstance(1, Color.CYAN);
                default:
                    return null;
            }
        }
    }

    public static class FragmentOne extends Fragment {

        private static final String MY_NUM_KEY = "num";
        private static final String MY_COLOR_KEY = "color";

        private int mNum;
        private int mColor;

        // You can modify the parameters to pass in whatever you want
        static FragmentOne newInstance(int num, int color) {
            FragmentOne f = new FragmentOne();
            Bundle args = new Bundle();
            args.putInt(MY_NUM_KEY, num);
            args.putInt(MY_COLOR_KEY, color);
            f.setArguments(args);
            return f;
        }

        @Override
        public void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
            mNum = getArguments() != null ? getArguments().getInt(MY_NUM_KEY) : 0;
            mColor = getArguments() != null ? getArguments().getInt(MY_COLOR_KEY) : Color.BLACK;
        }

        @Override
        public View onCreateView(LayoutInflater inflater, ViewGroup container,
                                 Bundle savedInstanceState) {
            View v = inflater.inflate(R.layout.fragment_one, container, false);
            v.setBackgroundColor(mColor);
            TextView textView = v.findViewById(R.id.textview);
            textView.setText("Page " + mNum);
            return v;
        }
    }
}

Finished

If you copied and pasted the three files above to your project, you should be able to run the app and see the result in the animation above.

Going on

There are quite a few things you can do with ViewPagers. See the following links to get started:

• Creating Swipe Views with Tabs
• ViewPager with FragmentPagerAdapter (CodePath tutorials are always good)

declare @cur cursor
declare @idx int       
declare @Approval_No varchar(50) 

declare @ReqNo varchar(100)
declare @M_Id  varchar(100)
declare @Mail_ID varchar(100)
declare @temp  table
(
val varchar(100)
)
declare @temp2  table
(
appno varchar(100),
mailid varchar(100),

)


    declare @slice varchar(8000)       
    declare @String varchar(100)
    --set @String = '1200096,1200095,1200094,1200093,1200092,1200092'
set @String = '20131'


    select @idx = 1       
        if len(@String)<1 or @String is null  return       

    while @idx!= 0       
    begin       
        set @idx = charindex(',',@String)       
        if @idx!=0       
            set @slice = left(@String,@idx - 1)       
        else       
            set @slice = @String

            --select @slice       
            insert into @temp values(@slice)
        set @String = right(@String,len(@String) - @idx)       
        if len(@String) = 0 break


    end
    -- select distinct(val) from @temp


SET @cur = CURSOR FOR select distinct(val) from @temp


--open cursor    
OPEN @cur    
--fetchng id into variable

    FROM @cur into @Approval_No 

      --
    --loop still the end    
     while @@FETCH_STATUS = 0  
    BEGIN   


select distinct(Approval_Sr_No) as asd, @ReqNo=Approval_Sr_No,@M_Id=AM_ID,@Mail_ID=Mail_ID from WFMS_PRAO,WFMS_USERMASTER where  WFMS_PRAO.AM_ID=WFMS_USERMASTER.User_ID

    CLOSE @cur    

select * from @tem

Use the following command:

in.nextLine();

right after

System.out.println("Invalid input. Please Try Again.");
System.out.println();

or after the following curly bracket (where your comment regarding it, is).

This command advances the scanner to the next line (when reading from a file or string, this simply reads the next line), thus essentially flushing it, in this case. It clears the buffer and readies the scanner for a new input. It can, preferably, be used for clearing the current buffer when a user has entered an invalid input (such as a letter when asked for a number).

Documentation of the method can be found here: http://docs.oracle.com/javase/7/docs/api/java/util/Scanner.html#nextLine()

Hope this helps!

You can also try this..

$this->getProduct()->getId();

When you don’t have access to $this you can use Magento registry:

$cpid=Mage::registry('current_product')->getId();

Your problem is:

for line in p.stdout:
    print(">>> " + str(line.rstrip()))
    p.stdout.flush()

the iterator itself has extra buffering.

Try doing like this:

while True:
  line = p.stdout.readline()
  if not line:
     break
  print line

You can use Twisted to verify certificates. The main API is CertificateOptions, which can be provided as the contextFactory argument to various functions such as listenSSL and startTLS.

Unfortunately, neither Python nor Twisted comes with a the pile of CA certificates required to actually do HTTPS validation, nor the HTTPS validation logic. Due to a limitation in PyOpenSSL, you can't do it completely correctly just yet, but thanks to the fact that almost all certificates include a subject commonName, you can get close enough.

Here is a naive sample implementation of a verifying Twisted HTTPS client which ignores wildcards and subjectAltName extensions, and uses the certificate-authority certificates present in the 'ca-certificates' package in most Ubuntu distributions. Try it with your favorite valid and invalid certificate sites :).

import os
import glob
from OpenSSL.SSL import Context, TLSv1_METHOD, VERIFY_PEER, VERIFY_FAIL_IF_NO_PEER_CERT, OP_NO_SSLv2
from OpenSSL.crypto import load_certificate, FILETYPE_PEM
from twisted.python.urlpath import URLPath
from twisted.internet.ssl import ContextFactory
from twisted.internet import reactor
from twisted.web.client import getPage
certificateAuthorityMap = {}
for certFileName in glob.glob("/etc/ssl/certs/*.pem"):
    # There might be some dead symlinks in there, so let's make sure it's real.
    if os.path.exists(certFileName):
        data = open(certFileName).read()
        x509 = load_certificate(FILETYPE_PEM, data)
        digest = x509.digest('sha1')
        # Now, de-duplicate in case the same cert has multiple names.
        certificateAuthorityMap[digest] = x509
class HTTPSVerifyingContextFactory(ContextFactory):
    def __init__(self, hostname):
        self.hostname = hostname
    isClient = True
    def getContext(self):
        ctx = Context(TLSv1_METHOD)
        store = ctx.get_cert_store()
        for value in certificateAuthorityMap.values():
            store.add_cert(value)
        ctx.set_verify(VERIFY_PEER | VERIFY_FAIL_IF_NO_PEER_CERT, self.verifyHostname)
        ctx.set_options(OP_NO_SSLv2)
        return ctx
    def verifyHostname(self, connection, x509, errno, depth, preverifyOK):
        if preverifyOK:
            if self.hostname != x509.get_subject().commonName:
                return False
        return preverifyOK
def secureGet(url):
    return getPage(url, HTTPSVerifyingContextFactory(URLPath.fromString(url).netloc))
def done(result):
    print 'Done!', len(result)
secureGet("https://google.com/").addCallback(done)
reactor.run()

When in doubt, read the documentation:

filename = "C:\Temp\vblist.txt"

Set fso = CreateObject("Scripting.FileSystemObject")
Set f = fso.OpenTextFile(filename)

Do Until f.AtEndOfStream
  WScript.Echo f.ReadLine
Loop

f.Close

You want the "popen" function. Here's an example of running the command "ls /etc" and outputing to the console.

#include <stdio.h>
#include <stdlib.h>


int main( int argc, char *argv[] )
{

  FILE *fp;
  char path[1035];

  /* Open the command for reading. */
  fp = popen("/bin/ls /etc/", "r");
  if (fp == NULL) {
    printf("Failed to run command\n" );
    exit(1);
  }

  /* Read the output a line at a time - output it. */
  while (fgets(path, sizeof(path), fp) != NULL) {
    printf("%s", path);
  }

  /* close */
  pclose(fp);

  return 0;
}

You can use datetime's strftime function to get this. The problem is that time's strftime accepts a timetuple that does not carry microsecond information.

from datetime import datetime
datetime.now().strftime("%H:%M:%S.%f")

Should do the trick!

The total of 7 numbers in an array can be created as:

import java.util.*;
class Sum
{
   public static void main(String arg[])
   {
     int a[]=new int[7];
     int total=0;
     Scanner n=new Scanner(System.in);
     System.out.println("Enter the no. for total");

     for(int i=0;i<=6;i++) 
     {
       a[i]=n.nextInt();
       total=total+a[i];
      }
       System.out.println("The total is :"+total);
    }
}

If you're not using gradle (creating a project from an APK, for instance), this can be done through the Android Studio UI (as of version 3.3.2):

• Right-click the project root directory, pick Open Module Settings
• Hit the + Add Content Root button (center right)
• Add your path and hit OK

In my experience (with native code), as long as your .so's are built with debug symbols and from the same absolute paths, breakpoints added in source files will be automatically recognized.

If display: inline; isn't working, try out display: inline-block;. :)

boolean state = "TURNED ON";

is not a Java valid code. boolean can receive only boolean values (true or false) and "TURNED ON"is a String.

EDIT:

now you are talking about a loop and your code does not contain any. your var state is false because the boolean default value and you execute the else clause.

A little piece of PHP to get the server to populate a JavaScript variable is quick and easy:

var my_javascript_variable = <?php echo json_encode($_POST['my_post'] ?? null) ?>;

Then just access the JavaScript variable in the normal way.

Note there is no guarantee any given data or kind of data will be posted unless you check - all input fields are suggestions, not guarantees.

The simple answer is that csv files should always be opened in binary mode whether for input or output, as otherwise on Windows there are problems with the line ending. Specifically on output the csv module will write \r\n (the standard CSV row terminator) and then (in text mode) the runtime will replace the \n by \r\n (the Windows standard line terminator) giving a result of \r\r\n.

Fiddling with the lineterminator is NOT the solution.

I recently faced similar issue where the atom editor will not close. Neither was responding. Kill / kill -9 / force exit from Activity Monitor - didn't work. Finally had to restart my mac to close the app.

I think this is a solved problem (see above), but there's an interesting side case to keep in mind because it might get asked:

If there are exactly 4,294,967,295 (2^32 - 1) 32-bit integers with no repeats, and therefore only one is missing, there is a simple solution.

Start a running total at zero, and for each integer in the file, add that integer with 32-bit overflow (effectively, runningTotal = (runningTotal + nextInteger) % 4294967296). Once complete, add 4294967296/2 to the running total, again with 32-bit overflow. Subtract this from 4294967296, and the result is the missing integer.

The "only one missing integer" problem is solvable with only one run, and only 64 bits of RAM dedicated to the data (32 for the running total, 32 to read in the next integer).

Corollary: The more general specification is extremely simple to match if we aren't concerned with how many bits the integer result must have. We just generate a big enough integer that it cannot be contained in the file we're given. Again, this takes up absolutely minimal RAM. See the pseudocode.

# Grab the file size
fseek(fp, 0L, SEEK_END);
sz = ftell(fp);
# Print a '2' for every bit of the file.
for (c=0; c<sz; c++) {
  for (b=0; b<4; b++) {
    print "2";
  }
}

I'm not allowed to write any comments yet, so I'll write an answer, if somebody will read all of them and reach this one.

If the index of the dataset is a datetime and you want to filter that just by (for example) months, you can do following:

df.loc[df.index.month == 3]

That will filter the dataset for you by March.

Pretty sure you can't do that, as it violates the purpose of uniques.

However, this person seems to have a decent work around: http://sqlservercodebook.blogspot.com/2008/04/multiple-null-values-in-unique-index-in.html

A general answer

select * from [dbo].[SplitString]('1,2',',') -- Will work 

but

select [dbo].[SplitString]('1,2',',')  -- will not work and throws this error

First create a Struc codable like this:

  struct JuzgadosList : Codable {
    var CP : Int
    var TEL : String
    var LOCAL : String
    var ORGANO : String
    var DIR : String
}

Now declare the variable

 var jzdosList = [JuzgadosList]()

Read from main directory

func getJsonFromDirectory() {

        if let path = Bundle.main.path(forResource: "juzgados", ofType: "json") {
            do {
                let data = try Data(contentsOf: URL(fileURLWithPath: path), options: .alwaysMapped)
                let jList = try JSONDecoder().decode([JuzgadosList].self, from: data)
                self.jzdosList = jList

                DispatchQueue.main.async() { () -> Void in
                    self.tableView.reloadData()
                }

            } catch let error {
                print("parse error: \(error.localizedDescription)")
            }
        } else {
            print("Invalid filename/path.")
        }
    }

Read from web

func getJsonFromUrl(){

        self.jzdosList.removeAll(keepingCapacity: false)

        print("Internet Connection Available!")

        guard let url = URL(string: "yourURL")  else { return }

        let request = URLRequest(url: url, cachePolicy: URLRequest.CachePolicy.reloadIgnoringLocalCacheData, timeoutInterval: 60.0)
        URLSession.shared.dataTask(with: request) { (data, response, err) in
            guard let data = data else { return }
            do {
                let jList = try JSONDecoder().decode([JuzgadosList].self, from: data)
                self.jzdosList = jList

                DispatchQueue.main.async() { () -> Void in
                    self.tableView.reloadData()
                }
            } catch let jsonErr {
                print("Error serializing json:", jsonErr)
            }
        }.resume()
    }

You can also combine the p3p.xml and policy.xml files as such:

/home/ubuntu/sites/shared/w3c/p3p.xml

I found the easiest way to add a header is proxy through Apache and use mod_headers, as such:

<VirtualHost *:80>
  ServerName mydomain.com

  DocumentRoot /home/ubuntu/sites/shared/w3c/

  ProxyRequests off
  ProxyPass /w3c/ !
  ProxyPass / http://127.0.0.1:8080/
  ProxyPassReverse / http://127.0.0.1:8080/
  ProxyPreserveHost on

  Header add p3p 'P3P:policyref="/w3c/p3p.xml", CP="NID DSP ALL COR"'
</VirtualHost>

So we proxy all requests except those to /w3c/p3p.xml to our application server.

You can test it all with the W3C validator

If you're trying to get data out of the request body, the code above works. But, I think you are having the same problem I was..

If the data in the body is in JSON form, and you want it as a Java object, you'll need to parse it yourself, or use a library like google-gson to handle it for you. You should look at the docs and examples at the project's website to know how to use it. It's fairly simple.

In my app I have app delegate and other classes that need to be accessed by the tests as public. As outlined here, I then import my my app into my tests.

When I recently created two new classes ,their test targets were both the main and testing parts. Removing them from their membership from the tests solved the issue.

Disadvantages

1. Client must enable javascript. Yes, this is a clear disadvantage of SPA. In my case I know that I can expect my users to have JavaScript enabled. If you can't then you can't do a SPA, period. That's like trying to deploy a .NET app to a machine without the .NET Framework installed.

2. Only one entry point to the site. I solve this problem using SammyJS. 2-3 days of work to get your routing properly set up, and people will be able to create deep-link bookmarks into your app that work correctly. Your server will only need to expose one endpoint - the "give me the HTML + CSS + JS for this app" endpoint (think of it as a download/update location for a precompiled application) - and the client-side JavaScript you write will handle the actual entry into the application.

3. Security. This issue is not unique to SPAs, you have to deal with security in exactly the same way when you have an "old-school" client-server app (the HATEOAS model of using Hypertext to link between pages). It's just that the user is making the requests rather than your JavaScript, and that the results are in HTML rather than JSON or some data format. In a non-SPA app you have to secure the individual pages on the server, whereas in a SPA app you have to secure the data endpoints. (And, if you don't want your client to have access to all the code, then you have to split apart the downloadable JavaScript into separate areas as well. I simply tie that into my SammyJS-based routing system so the browser only requests things that the client knows it should have access to, based on an initial load of the user's roles, and then that becomes a non-issue.)

Advantages

1. A major architectural advantage of a SPA (that rarely gets mentioned) in many cases is the huge reduction in the "chattiness" of your app. If you design it properly to handle most processing on the client (the whole point, after all), then the number of requests to the server (read "possibilities for 503 errors that wreck your user experience") is dramatically reduced. In fact, a SPA makes it possible to do entirely offline processing, which is huge in some situations.

2. Performance is certainly better with client-side rendering if you do it right, but this is not the most compelling reason to build a SPA. (Network speeds are improving, after all.) Don't make the case for SPA on this basis alone.

3. Flexibility in your UI design is perhaps the other major advantage that I have found. Once I defined my API (with an SDK in JavaScript), I was able to completely rewrite my front-end with zero impact on the server aside from some static resource files. Try doing that with a traditional MVC app! :) (This becomes valuable when you have live deployments and version consistency of your API to worry about.)

So, bottom line: If you need offline processing (or at least want your clients to be able to survive occasional server outages) - dramatically reducing your own hardware costs - and you can assume JavaScript & modern browsers, then you need a SPA. In other cases it's more of a tradeoff.

In html

button ng-click="myMethod()">Videos</button>

In angular

 $scope.myMethod = function () {
         $(".collapse").collapse('hide');    //if you want to hide
         $(".collapse").collapse('toggle');  //if you want toggle
         $(".collapse").collapse('show');    //if you want to show
}

Converting the encoding of the source file from UTF-16 to UTF-8 solve my problem.

How to convert a file to utf-8 in Python?

import codecs
BLOCKSIZE = 1048576 # or some other, desired size in bytes
with codecs.open(sourceFileName, "r", "utf-16") as sourceFile:
    with codecs.open(targetFileName, "w", "utf-8") as targetFile:
        while True:
            contents = sourceFile.read(BLOCKSIZE)
            if not contents:
                break
            targetFile.write(contents)

setInterval returns an id that you can use to cancel the interval with clearInterval()

No, it's not possible.

It's really, if not use native selects, if you create custom select widget from html elements, t.e. "li".

If I get 'someObject', say via

someObject <- myMagicFunction(...)

then I usually proceed by

class(someObject)
str(someObject)

which can be followed by head(), summary(), print(), ... depending on the class you have.

Using groupby you could split into two dataframes like

In [1047]: df1, df2 = [x for _, x in df.groupby(df['Sales'] < 30)]

In [1048]: df1
Out[1048]:
   A  Sales
2  7     30
3  6     40
4  1     50

In [1049]: df2
Out[1049]:
   A  Sales
0  3     10
1  4     20

You are only scrolling the height of your element. offset() returns the coordinates of an element relative to the document, and top param will give you the element's distance in pixels along the y-axis:

$("html, body").animate({ scrollTop: $('#title1').offset().top }, 1000);

And you can also add a delay to it:

$("html, body").delay(2000).animate({scrollTop: $('#title1').offset().top }, 2000);

The simple and best solution is to use tables for layouts. You're doing it right. There are a number of reasons tables are better.

• They perform better than CSS
• They work on all browsers without any fuss
• You can debug them easily with the border=1 attribute

Because I often find myself working with multiple environment variables, I find it useful to keep them in a separate .env file (make sure to ignore this from your source control). Then (in Linux) prepend export $(cat .env | xargs) && in your script command before starting your app.

Example .env file:

VAR_A=Hello World
VAR_B=format the .env file like this with new vars separated by a line break

Example index.js:

console.log('Test', process.env.VAR_A, process.env.VAR_B);

Example package.json:

{
  ...
  "scripts": {
    "start": "node index.js",

    "env-linux": "export $(cat .env | xargs) && env",
    "start-linux": "export $(cat .env | xargs) && npm start",

    "env-windows": "(for /F \"tokens=*\" %i in (.env) do set %i)",
    "start-windows": "(for /F \"tokens=*\" %i in (.env) do set %i) && npm start",

  }
  ...
}

Unfortunately I can't seem to set the environment variables by calling a script from a script -- like "start-windows": "npm run env-windows && npm start" -- so there is some redundancy in the scripts.

For a test you can see the env variables by running npm run env-linux or npm run env-windows, and test that they make it into your app by running npm run start-linux or npm run start-windows.

you can download .whl in LFD . Then use "pip install ***.whl" in CMD

The problem is that they're all the same exact list in memory. When you use the [x]*n syntax, what you get is a list of n many x objects, but they're all references to the same object. They're not distinct instances, rather, just n references to the same instance.

To make a list of 3 different lists, do this:

x = [[] for i in range(3)]

This gives you 3 separate instances of [], which is what you want

[[]]*n is similar to

l = []
x = []
for i in range(n):
    x.append(l)

While [[] for i in range(3)] is similar to:

x = []
for i in range(n):
    x.append([])   # appending a new list!

In [20]: x = [[]] * 4

In [21]: [id(i) for i in x]
Out[21]: [164363948, 164363948, 164363948, 164363948] # same id()'s for each list,i.e same object


In [22]: x=[[] for i in range(4)]

In [23]: [id(i) for i in x]
Out[23]: [164382060, 164364140, 164363628, 164381292] #different id(), i.e unique objects this time

class Program
{
    static void Main(string[] args)
    {
        String unicodeString =
        "This Unicode string contains two characters " +
        "with codes outside the traditional ASCII code range, " +
        "Pi (\u03a0) and Sigma (\u03a3).";

        Console.WriteLine("Original string:");
        Console.WriteLine(unicodeString);
        UnicodeEncoding unicodeEncoding = new UnicodeEncoding();
        byte[] utf16Bytes = unicodeEncoding.GetBytes(unicodeString);
        char[] chars = unicodeEncoding.GetChars(utf16Bytes, 2, utf16Bytes.Length - 2);
        string s = new string(chars);
        Console.WriteLine();
        Console.WriteLine("Char Array:");
        foreach (char c in chars) Console.Write(c);
        Console.WriteLine();
        Console.WriteLine();
        Console.WriteLine("String from Char Array:");
        Console.WriteLine(s);

        Console.ReadKey();
    }
}

you can also add below code in AndroidManifest.xml.

android:icon="@android:color/transparent"

It will work fine.

But I found that this gives a problem as the launcher icon also become transparent.

So I used:

getActionBar().setIcon(new ColorDrawable(getResources().getColor(android.R.color.transparent)));

and it worked fine.

But if you are having more than one activity and want to make the icon on an activity transparent then the previous approach will work.

This should get your sorted:

• Highlight from the end of the first line, to the very beginning of the third line.
• Use the Ctrl + H to bring up the 'Find and Replace' window.
• The highlighed region will already be plased in the 'Find' textbox.
• Replace with: \r\n
• 'Replace All' will then remove all the additional line spaces not required.

Here's how it should look:

(d means decimal, b means binary)

1. 12.25d is your float.
2. You write 12d in binary and remove it from your float. Only the remainder (.25d) will be left.
3. You write the dot.
4. While the remainder (0.25d) is not zero (and/or you want more digits), multiply it with 2 (-> 0.50d), remove and write the digit left of the dot (0), and continue with the new remainder (.50d).

I've found yet another reason for spy to call the original method.

Someone had the idea to mock a final class, and found about MockMaker:

As this works differently to our current mechanism and this one has different limitations and as we want to gather experience and user feedback, this feature had to be explicitly activated to be available ; it can be done via the mockito extension mechanism by creating the file src/test/resources/mockito-extensions/org.mockito.plugins.MockMaker containing a single line: mock-maker-inline

Source: https://github.com/mockito/mockito/wiki/What%27s-new-in-Mockito-2#mock-the-unmockable-opt-in-mocking-of-final-classesmethods

After I merged and brought that file to my machine, my tests failed.

I just had to remove the line (or the file), and spy() worked.
