I had the same issue and the problem was the size of the picture. Whatsapp doesn't support picture with a size greater than 300KB.

So the most important property to display image on Whatsapp is:

<meta property="og:image" content="url_image">

And the size of the image to display must be less than 300KB

This only works after you save a bookmark to the app to the home screen. Not if you just browse to the site normally.

Do you want to make the label (except for the text) transparent? Windows Forms (I assume WinForms - is this true) doesn't really support transparency. The easiest way, sometimes, is Label's Backcolor to Transparent.

label1.BackColor = System.Drawing.Color.Transparent;

You will run into problems though, as WinForms really doesn't properly support transparency. Otherwise, see here:

http://www.doogal.co.uk/transparent.php

http://www.daniweb.com/code/snippet216425.html

Setting the parent of a usercontrol prevents it from being transparent

Good luck!

Just some minor modification to your code will do (with some var renaming for clarity) :

double sum = 0; //average will have decimal point

for(int i=0; i < args.length; i++){
   //parse string to double, note that this might fail if you encounter a non-numeric string
   //Note that we could also do Integer.valueOf( args[i] ) but this is more flexible
   sum += Double.valueOf( args[i] ); 
}

double average = sum/args.length;

System.out.println(average );

Note that the loop can also be simplified:

for(String arg : args){
   sum += Double.valueOf( arg );
}

Edit: the OP seems to want to use the args array. This seems to be a String array, thus updated the answer accordingly.

Update:

As zoxqoj correctly pointed out, integer/double overflow is not taken care of in the code above. Although I assume the input values will be small enough to not have that problem, here's a snippet to use for really large input values:

BigDecimal sum = BigDecimal.ZERO;
for(String arg : args){
  sum = sum.add( new BigDecimal( arg ) );
}

This approach has several advantages (despite being somewhat slower, so don't use it for time critical operations):

• Precision is kept, with double you will gradually loose precision with the number of math operations (or not get exact precision at all, depending on the numbers)
• The probability of overflow is practically eliminated. Note however, that a BigDecimal might be bigger than what fits into a double or long.

You can’t use \s in Java to match white space on its own native character set, because Java doesn’t support the Unicode white space property — even though doing so is strictly required to meet UTS#18’s RL1.2! What it does have is not standards-conforming, alas.

Unicode defines 26 code points as \p{White_Space}: 20 of them are various sorts of \pZ GeneralCategory=Separator, and the remaining 6 are \p{Cc} GeneralCategory=Control.

White space is a pretty stable property, and those same ones have been around virtually forever. Even so, Java has no property that conforms to The Unicode Standard for these, so you instead have to use code like this:

String whitespace_chars =  ""       /* dummy empty string for homogeneity */
                        + "\\u0009" // CHARACTER TABULATION
                        + "\\u000A" // LINE FEED (LF)
                        + "\\u000B" // LINE TABULATION
                        + "\\u000C" // FORM FEED (FF)
                        + "\\u000D" // CARRIAGE RETURN (CR)
                        + "\\u0020" // SPACE
                        + "\\u0085" // NEXT LINE (NEL) 
                        + "\\u00A0" // NO-BREAK SPACE
                        + "\\u1680" // OGHAM SPACE MARK
                        + "\\u180E" // MONGOLIAN VOWEL SEPARATOR
                        + "\\u2000" // EN QUAD 
                        + "\\u2001" // EM QUAD 
                        + "\\u2002" // EN SPACE
                        + "\\u2003" // EM SPACE
                        + "\\u2004" // THREE-PER-EM SPACE
                        + "\\u2005" // FOUR-PER-EM SPACE
                        + "\\u2006" // SIX-PER-EM SPACE
                        + "\\u2007" // FIGURE SPACE
                        + "\\u2008" // PUNCTUATION SPACE
                        + "\\u2009" // THIN SPACE
                        + "\\u200A" // HAIR SPACE
                        + "\\u2028" // LINE SEPARATOR
                        + "\\u2029" // PARAGRAPH SEPARATOR
                        + "\\u202F" // NARROW NO-BREAK SPACE
                        + "\\u205F" // MEDIUM MATHEMATICAL SPACE
                        + "\\u3000" // IDEOGRAPHIC SPACE
                        ;        
/* A \s that actually works for Java’s native character set: Unicode */
String     whitespace_charclass = "["  + whitespace_chars + "]";    
/* A \S that actually works for  Java’s native character set: Unicode */
String not_whitespace_charclass = "[^" + whitespace_chars + "]";

Now you can use whitespace_charclass + "+" as the pattern in your replaceAll.

Sorry ’bout all that. Java’s regexes just don’t work very well on its own native character set, and so you really have to jump through exotic hoops to make them work.

And if you think white space is bad, you should see what you have to do to get \w and \b to finally behave properly!

Yes, it’s possible, and yes, it’s a mindnumbing mess. That’s being charitable, even. The easiest way to get a standards-comforming regex library for Java is to JNI over to ICU’s stuff. That’s what Google does for Android, because OraSun’s doesn’t measure up.

If you don’t want to do that but still want to stick with Java, I have a front-end regex rewriting library I wrote that “fixes” Java’s patterns, at least to get them conform to the requirements of RL1.2a in UTS#18, Unicode Regular Expressions.

Use the @ViewChildren decorator combined with QueryList. Both of these are from "@angular/core"

@ViewChildren(CustomComponent) customComponentChildren: QueryList<CustomComponent>;

Doing something with each child looks like: this.customComponentChildren.forEach((child) => { child.stuff = 'y' })

There is further documentation to be had at angular.io, specifically: https://angular.io/docs/ts/latest/cookbook/component-communication.html#!#sts=Parent%20calls%20a%20ViewChild

A other users suggested,

.empty()

is good enought, because it removes all descendant nodes (both tag-nodes and text-nodes) AND all kind of data stored inside those nodes. See the JQuery's API empty documentation.

If you wish to keep data, like event handlers for example, you should use

.detach()

as described on the JQuery's API detach documentation.

The method .remove() could be usefull for similar purposes.

The reason not to use ICloneable is not because it doesn't have a generic interface. The reason not to use it is because it's vague. It doesn't make clear whether you're getting a shallow or a deep copy; that's up to the implementer.

Yes, MemberwiseClone makes a shallow copy, but the opposite of MemberwiseClone isn't Clone; it would be, perhaps, DeepClone, which doesn't exist. When you use an object through its ICloneable interface, you can't know which kind of cloning the underlying object performs. (And XML comments won't make it clear, because you'll get the interface comments rather than the ones on the object's Clone method.)

What I usually do is simply make a Copy method that does exactly what I want.

I can make things work this way:

inside javascript junction that is executed by the html button:

document.getElementById("<%= Button2.ClientID %>").click();

ASP button inside div:

<div id="submitBtn" style="display: none;">
   <asp:Button ID="Button2" runat="server" Text="Submit" ValidationGroup="AllValidators" OnClick="Button2_Click" />
</div>

Everything runs from the .cs file except that the code below doesn't execute. There is no message box and redirect to the same page (refresh all boxes):

 int count = cmd.ExecuteNonQuery();
 if (count > 0)
 {
   cmd2.CommandText = insertSuperRoster;
   cmd2.Connection = con;
   cmd2.ExecuteNonQuery();
   string url = "VaccineRefusal.aspx";
   ClientScript.RegisterStartupScript(this.GetType(), "callfunction", "alert('Data Inserted Successfully!');window.location.href = '" + url + "';", true);
  }

Any ideas why these lines won't execute?

Consider your REST API returns:

{"Intent":{"Command":"search","SubIntent":null}}

Then you can do the following to print it in a nice format:

<pre id="ciResponseText">Output will de displayed here.</pre>   

var ciResponseText = document.getElementById('ciResponseText');
var obj = JSON.parse(http.response);
ciResponseText.innerHTML = JSON.stringify(obj, undefined, 2);   

If you desire to use Python 3, you can use the following:

import json
import urllib.request
req = urllib.request.Request('url')
with urllib.request.urlopen(req) as response:
    result = json.loads(response.readall().decode('utf-8'))

Not sure if the most efficient way, but this worked for me:

from pyspark.sql.functions import col

df1.alias('a').join(df2.alias('b'),col('b.id') == col('a.id')).select([col('a.'+xx) for xx in a.columns] + [col('b.other1'),col('b.other2')])

The trick is in:

[col('a.'+xx) for xx in a.columns] : all columns in a

[col('b.other1'),col('b.other2')] : some columns of b

you can do it like this:

cell[B1]: 0:04:58.727

cell[B2]: =FIND(".";B1)

cell[B3]: =LEFT(B1;B2-7)

cell[B4]: =MID(B1;11-8;2)

cell[B5]: =RIGHT(B1;6)

cell[B6]: =B3*3600000+B4*60000+B5

maybe you have to multiply B5 also with 1000.

=FIND(".";B1) is only necessary because you might have inputs like '0:04:58.727' or '10:04:58.727' with different length.

An alternative setting is to have the default virtual host at the end of the config file rather than the beginning. This way, all alternative virtual hosts will be checked before being matched by the default virtual host.

Example:

NameVirtualHost *:80
Listen 80

...

<VirtualHost *:80>
        ServerName host1
        DocumentRoot /someDir
</VirtualHost>

<VirtualHost *:80>
        ServerName host2
        DocumentRoot /someOtherDir
</VirtualHost>

<VirtualHost *:80>
        DocumentRoot /defaultDir
</VirtualHost>

Why not just create a setup project? It's really easy.

1. Add a service installer to the service (you do it on the seemingly useless service "design" surface)
2. Create a setup project and add the Service output to the setup app folder
3. Most importantly add the Service project output to all the custom actions

Voila, and you're done.

See here for more: http://www.codeproject.com/KB/dotnet/simplewindowsservice.aspx

There is also a way to prompt the user for credentials (or supply your own).

import string

asking = "".join(l for l in asking if l not in string.punctuation)

filter with string.punctuation.

1. Remove the podfile name from .plist
2. Reinstall the pod again (use this link for pod installation)

You should try this syntax - assuming you want to have @OrderID as a parameter for your stored procedure:

CREATE PROCEDURE dbo.YourStoredProcNameHere
   @OrderID INT
AS
BEGIN
 DECLARE @OrderItemID AS INT
 DECLARE @AppointmentID AS INT
 DECLARE @PurchaseOrderID AS INT
 DECLARE @PurchaseOrderItemID AS INT
 DECLARE @SalesOrderID AS INT
 DECLARE @SalesOrderItemID AS INT

 SELECT @OrderItemID = OrderItemID 
 FROM [OrderItem] 
 WHERE OrderID = @OrderID

 SELECT @AppointmentID = AppoinmentID 
 FROM [Appointment] 
 WHERE OrderID = @OrderID

 SELECT @PurchaseOrderID = PurchaseOrderID 
 FROM [PurchaseOrder] 
 WHERE OrderID = @OrderID

END

OF course, that only works if you're returning exactly one value (not multiple values!)

"Dino TW" has provided the link to the comment Hibernate Mapping Exception : Repeated column in mapping for entity which has the vital information.

The link hints to provide "inverse=true" in the set mapping, I tried it and it actually works. It is such a rare situation wherein a Set and Composite key come together. Make inverse=true, we leave the insert & update of the table with Composite key to be taken care by itself.

Below can be the required mapping,

<class name="com.example.CompanyEntity" table="COMPANY">
    <id name="id" column="COMPANY_ID"/>
    <set name="names" inverse="true" table="COMPANY_NAME" cascade="all-delete-orphan" fetch="join" batch-size="1" lazy="false">
        <key column="COMPANY_ID" not-null="true"/>
        <one-to-many entity-name="vendorName"/>
    </set>
</class>

Swift 3:

        static func imageFromColor(color: UIColor, width: CGFloat, height: CGFloat) -> UIImage {
            let rect = CGRect(x: 0, y: 0, width: width, height: height)
            UIGraphicsBeginImageContext(rect.size)
            let context = UIGraphicsGetCurrentContext()!
            context.setFillColor(color.cgColor)
            context.fill(rect)
            let img = UIGraphicsGetImageFromCurrentImageContext()!
            UIGraphicsEndImageContext()
            return img
        }

        let button = UIButton(type: .system)
        let image = imageFromColor(color: .red, width: 
        button.frame.size.width, height: button.frame.size.height)
        button.setBackgroundImage(image, for: .normal)

You can simply do tar -xvf <rpm file> as well!

Go into settings in Package Center and add http://packages.synocommunity.com/ as a package source. Then you should be able to add it easily via Package Center.

Try this for selecting div by first id

$('div[id^="c-"]')

The subquery option has already been answered, but note that in many cases a LEFT JOIN can be a faster way to do this:

SELECT table1.*
FROM table1 LEFT JOIN table2 ON table2.principal=table1.principal
WHERE table2.principal IS NULL

If you want to check multiple tables to make sure it's not present in any of the tables (like in SRKR's comment), you can use this:

SELECT table1.*
FROM table1
LEFT JOIN table2 ON table2.name=table1.name
LEFT JOIN table3 ON table3.name=table1.name
WHERE table2.name IS NULL AND table3.name IS NULL

Firing application wide events

How to make controllers talk to each other ...

In addition to the very great answer above I want to mention application wide events which can be very useful in an MVC setup to enable communication between controllers. (extjs4.1)

Lets say we have a controller Station (Sencha MVC examples) with a select box:

Ext.define('Pandora.controller.Station', {
    extend: 'Ext.app.Controller',
    ...

    init: function() {
        this.control({
            'stationslist': {
                selectionchange: this.onStationSelect
            },
            ...
        });
    },

    ...

    onStationSelect: function(selModel, selection) {
        this.application.fireEvent('stationstart', selection[0]);
    },    
   ...
});

When the select box triggers a change event, the function onStationSelect is fired.

Within that function we see:

this.application.fireEvent('stationstart', selection[0]);

This creates and fires an application wide event that we can listen to from any other controller.

Thus in another controller we can now know when the station select box has been changed. This is done through listening to this.application.on as follows:

Ext.define('Pandora.controller.Song', {
    extend: 'Ext.app.Controller', 
    ...
    init: function() {
        this.control({
            'recentlyplayedscroller': {
                selectionchange: this.onSongSelect
            }
        });

        // Listen for an application wide event
        this.application.on({
            stationstart: this.onStationStart, 
                scope: this
        });
    },
    ....
    onStationStart: function(station) {
        console.info('I called to inform you that the Station controller select box just has been changed');
        console.info('Now what do you want to do next?');
    },
}

If the selectbox has been changed we now fire the function onStationStart in the controller Song also ...

From the Sencha docs:

Application events are extremely useful for events that have many controllers. Instead of listening for the same view event in each of these controllers, only one controller listens for the view event and fires an application-wide event that the others can listen for. This also allows controllers to communicate with one another without knowing about or depending on each other’s existence.

In my case: Clicking on a tree node to update data in a grid panel.

Update 2016 thanks to @gm2008 from the comments below:

In terms of firing application-wide custom events, there is a new method now after ExtJS V5.1 is published, which is using Ext.GlobalEvents.

When you fire events, you can call: Ext.GlobalEvents.fireEvent('custom_event');

When you register a handler of the event, you call: Ext.GlobalEvents.on('custom_event', function(arguments){/* handler codes*/}, scope);

This method is not limited to controllers. Any component can handle a custom event through putting the component object as the input parameter scope.

Found in Sencha Docs: MVC Part 2

If you want to use form's reset feature, you'd better to use this:

$('input[type=checkbox]').prop('checked',true); 

OR

$('input[type=checkbox]').prop('checked',false);

Looks like removeAttr() can not be reset by form.reset().

If you are concerned about memory footprint, the Python standard library contains the array module; these arrays contain elements of the same type.

Found an incredibly useful answer here: How to run different python versions in cmd?

I would suggest using the Python Launcher for Windows utility that introduced was into Python 3.3 a while ago. You can also manually download and install it directly from the author's website for use with earlier versions of Python 2 and 3.

Regardless of how you obtain it, after installation it will have associated itself with all the standard Python file extensions (i.e. .py, .pyw, .pyc, and .pyo files). You'll not only be able to explicitly control which version is used at the command-prompt, but also on a script-by-script basis by adding Linux/Unix-y shebang #!/usr/bin/env pythonX comments at the beginning of your Python scripts.

As J.F. Sebastian suggests, Python Launcher for Windows is the best and default choice for launching different version of Python in Windows. It used to be a third-party tool, but now it is officially supported since Python 3.3.

New in version 3.3.

The Python launcher for Windows is a utility which aids in the location and execution of different Python versions. It allows scripts (or the command-line) to indicate a preference for a specific Python version, and will locate and execute that version.

This is a great tool just use it!

I used ALTER DATABASE mydb DEFAULT COLLATE utf8_unicode_ci;, but didn't work.

In this query:

Select * from table1, table2 where table1.field = date_format(table2.field,'%H');

This work for me:

Select * from table1, table2 where concat(table1.field) = date_format(table2.field,'%H');

Yes, only a concat.

You can achieve an expected result with requests library as well:

import requests

url = "http://www.mywebsite.org/Data%20Set.zip"

print(f"Before: {url}")
print(f"After:  {requests.utils.unquote(url)}")

Output:

$ python3 test_url_unquote.py

Before: http://www.mywebsite.org/Data%20Set.zip
After:  http://www.mywebsite.org/Data Set.zip

Might be handy if you are already using requests, without using another library for this job.

Use Element#outerHTML:

var el = document.createElement("p");
el.appendChild(document.createTextNode("Test"));

console.log(el.outerHTML);

It can also be used to write DOM elements. From Mozilla's documentation:

The outerHTML attribute of the element DOM interface gets the serialized HTML fragment describing the element including its descendants. It can be set to replace the element with nodes parsed from the given string.

https://developer.mozilla.org/en-US/docs/Web/API/Element/outerHTML

Quick and simple do this:

file_put_contents($filename, var_export($myArray, true));

If you even plan on merging your branch, I highly suggest you look at this:

Svnmerge.py

I hear Subversion 1.5 builds more of the merge tracking in, I have no experience with that. My project is on 1.4.x and svnmerge.py is a life saver!

With introduction of React hooks the state management (including forms state) became very simple and, in my opinion, way more understandable and predictable comparing with magic of other frameworks. For example:

const MyComponent = () => {
    const [value, setValue] = React.useState('some initial value');
    return <input value={value} onChange={e => setValue(e.target.value)} />;
}

This one-way flow makes it trivial to understand how the data is updated and when rendering happens. Simple but powerful to do any complex stuff in predictable and clear way. In this case, do "two-way" form state binding.

The example uses the primitive string value. Complex state management, eg. objects, arrays, nested data, can be managed this way too, but it is easier with help of libraries, like Hookstate (Disclaimer: I am the author of this library). Here is the example of complex state management.

When a form grows, there is an issue with rendering performance: form state is changed (so rerendering is needed) on every keystroke on any form field. This issue is also addressed by Hookstate. Here is the example of the form with 5000 fields: the state is updated on every keystore and there is no performance lag at all.

Edit: thought of something else.

You say you're creating a form dynamically - do you really mean a <form> and its contents 'cause asp.net takes issue with multiple forms on a page and it's already creating one uberform for you.

I was driving myself crazy with this exact problem. My JSON Marshaller and Unmarshaller were not populating my Go struct. Then I found the solution at https://eager.io/blog/go-and-json:

"As with all structs in Go, it’s important to remember that only fields with a capital first letter are visible to external programs like the JSON Marshaller."

After that, my Marshaller and Unmarshaller worked perfectly!

Was able to set the auth using the HttpsURLConnection

           URL myUrl = new URL(httpsURL);
            HttpsURLConnection conn = (HttpsURLConnection)myUrl.openConnection();
            String userpass = username + ":" + password;
            String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userpass.getBytes()));
            //httpsurlconnection
            conn.setRequestProperty("Authorization", basicAuth);

_{This more of a very important comment}

Key to understanding why vitaminwater's answer works are three things:

1. Know that UITextView is a subclass of UIScrollView class
2. Understand how ScrollView works and how its contentSize is calculated. For more see this here answer and its various solutions and comments.
3. Understand what contentSize is and how its calculated. See here and here. It might also help that setting contentOffset is likely nothing but:

func setContentOffset(offset: CGPoint)
{
    CGRect bounds = self.bounds
    bounds.origin = offset
    self.bounds = bounds
}

For more see objc scrollview and understanding scrollview

Combining the three together you'd easily understand that you need allow the the textView's intrinsic contentSize to work along AutoLayout constraints of the textView to drive the logic. It's almost as if you're textView is functioning like a UILabel

To make that happen you need to disable scrolling which basically means the scrollView's size, the contentSize's size and in case of adding a containerView, then the containerView's size would all be the same. When they're the same you have NO scrolling. And you'd have 0 contentOffset. Having 0 contentOffSet means you've not scrolled down. Not even a 1 point down! As a result the textView will be all stretched out.

It's also worth nothing that 0 contentOffset means that the scrollView's bounds and frame are identical. If you scroll down 5 points then your contentOffset would be 5, while your scrollView.bounds.origin.y - scrollView.frame.origin.y would be equal to 5

Your ngModel is not working because it's not a part of your NgModule yet.

You have to tell the NgModule that you have authority to use ngModel throughout your app, You can do it by adding FormsModule into your app.module.ts -> imports-> [].

import { FormsModule } from '@angular/forms';

@NgModule({

   imports: [ FormsModule ],       // HERE

   declarations: [ AppComponent ],
   bootstrap: [ AppComponent ]
 })

When something in the state has changed and you need to call a side effect (like a request to api - get, put, post, delete). So you need to call componentDidUpdate() because componentDidMount() is already called.

After calling side effect in componentDidUpdate(), you can set the state to new value based on the response data in the then((response) => this.setState({newValue: "here"})). Please make sure that you need to check prevProps or prevState to avoid infinite loop because when setting state to a new value, the componentDidUpdate() will call again.

There are 2 places to call a side effect for best practice - componentDidMount() and componentDidUpdate()

The title of this question at the time of writing is

SQL NOT IN constraint and NULL values

From the text of the question it appears that the problem was occurring in a SQL DML SELECT query, rather than a SQL DDL CONSTRAINT.

However, especially given the wording of the title, I want to point out that some statements made here are potentially misleading statements, those along the lines of (paraphrasing)

When the predicate evaluates to UNKNOWN you don't get any rows.

Although this is the case for SQL DML, when considering constraints the effect is different.

Consider this very simple table with two constraints taken directly from the predicates in the question (and addressed in an excellent answer by @Brannon):

DECLARE @T TABLE 
(
 true CHAR(4) DEFAULT 'true' NOT NULL, 
 CHECK ( 3 IN (1, 2, 3, NULL )), 
 CHECK ( 3 NOT IN (1, 2, NULL ))
);

INSERT INTO @T VALUES ('true');

SELECT COUNT(*) AS tally FROM @T;

As per @Brannon's answer, the first constraint (using IN) evaluates to TRUE and the second constraint (using NOT IN) evaluates to UNKNOWN. However, the insert succeeds! Therefore, in this case it is not strictly correct to say, "you don't get any rows" because we have indeed got a row inserted as a result.

The above effect is indeed the correct one as regards the SQL-92 Standard. Compare and contrast the following section from the SQL-92 spec

7.6 where clause

The result of the is a table of those rows of T for which the result of the search condition is true.

4.10 Integrity constraints

A table check constraint is satisfied if and only if the specified search condition is not false for any row of a table.

In other words:

In SQL DML, rows are removed from the result when the WHERE evaluates to UNKNOWN because it does not satisfy the condition "is true".

In SQL DDL (i.e. constraints), rows are not removed from the result when they evaluate to UNKNOWN because it does satisfy the condition "is not false".

Although the effects in SQL DML and SQL DDL respectively may seem contradictory, there is practical reason for giving UNKNOWN results the 'benefit of the doubt' by allowing them to satisfy a constraint (more correctly, allowing them to not fail to satisfy a constraint): without this behaviour, every constraints would have to explicitly handle nulls and that would be very unsatisfactory from a language design perspective (not to mention, a right pain for coders!)

p.s. if you are finding it as challenging to follow such logic as "unknown does not fail to satisfy a constraint" as I am to write it, then consider you can dispense with all this simply by avoiding nullable columns in SQL DDL and anything in SQL DML that produces nulls (e.g. outer joins)!

For localhost on XAMPP. Open a cmd window and type

cd C:\xampp\mysql\bin
mysql.exe -u root -p

Attention! No semi-colon after -p Enter your password and type

use database_name;

to select the database you need.

Check if your table is there

show tables;

Import from your sql file

source sqlfile.sql;

I have put my file on C:\xampp\mysql\bin location in order to don't mix up with locations of sql file.

Also remember that it must be:

#include "stdafx.h"
#include <iostream>

and not the other way around

#include <iostream>
#include "stdafx.h"

The following steps work fine on macOS Sierra 10.12.4. Note that after brew installs Docker, the docker command (symbolic link) is not available at /usr/local/bin. Running the Docker app for the first time creates this symbolic link. See the detailed steps below.

1. Install Docker.

   brew cask install docker
   

2. Launch Docker.

   • Press ? + Space to bring up Spotlight Search and enter Docker to launch Docker.
   • In the Docker needs privileged access dialog box, click OK.
   • Enter password and click OK.

   When Docker is launched in this manner, a Docker whale icon appears in the status menu. As soon as the whale icon appears, the symbolic links for docker, docker-compose, docker-credential-osxkeychain and docker-machine are created in /usr/local/bin.

   $ ls -l /usr/local/bin/docker*
   lrwxr-xr-x  1 susam  domain Users  67 Apr 12 14:14 /usr/local/bin/docker -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-compose -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-compose
   lrwxr-xr-x  1 susam  domain Users  90 Apr 12 14:14 /usr/local/bin/docker-credential-osxkeychain -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-credential-osxkeychain
   lrwxr-xr-x  1 susam  domain Users  75 Apr 12 14:14 /usr/local/bin/docker-machine -> /Users/susam/Library/Group Containers/group.com.docker/bin/docker-machine
   

3. Click on the docker whale icon in the status menu and wait for it to show Docker is running.

   

4. Test that docker works fine.

   $ docker run hello-world
   Unable to find image 'hello-world:latest' locally
   latest: Pulling from library/hello-world
   78445dd45222: Pull complete
   Digest: sha256:c5515758d4c5e1e838e9cd307f6c6a0d620b5e07e6f927b07d05f6d12a1ac8d7
   Status: Downloaded newer image for hello-world:latest
   
   Hello from Docker!
   This message shows that your installation appears to be working correctly.
   
   To generate this message, Docker took the following steps:
    1. The Docker client contacted the Docker daemon.
    2. The Docker daemon pulled the "hello-world" image from the Docker Hub.
    3. The Docker daemon created a new container from that image which runs the
       executable that produces the output you are currently reading.
    4. The Docker daemon streamed that output to the Docker client, which sent it
       to your terminal.
   
   To try something more ambitious, you can run an Ubuntu container with:
    $ docker run -it ubuntu bash
   
   Share images, automate workflows, and more with a free Docker ID:

5. If you are going to use docker-machine to create virtual machines, install VirtualBox.

   brew cask install virtualbox
   

   Note that if VirtualBox is not installed, then docker-machine fails with the following error.

   $ docker-machine create manager
   Running pre-create checks...
   Error with pre-create check: "VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path"
   

As an alternative to the chosen answer, and with the same safe semantics of Marcel's, here is a compact way of using a Python dictionary to specify the values. It has the benefit of being easy to modify as you add or remove columns to insert:

  meta_cols=('SongName','SongArtist','SongAlbum','SongGenre')
  insert='insert into Songs ({0}) values ({1})'.
        .format(','.join(meta_cols), ','.join( ['%s']*len(meta_cols) ))
  args = [ meta[i] for i in meta_cols ]
  cursor=db.cursor()
  cursor.execute(insert,args)
  db.commit()

Where meta is the dictionary holding the values to insert. Update can be done in the same way:

  meta_cols=('SongName','SongArtist','SongAlbum','SongGenre')
  update='update Songs set {0} where id=%s'.
        .format(','.join([ '{0}=%s'.format(c) for c in meta_cols ]))
  args = [ meta[i] for i in meta_cols ]
  args.append( songid )
  cursor=db.cursor()
  cursor.execute(update,args)
  db.commit()

Generally speaking an HTTP POST assumes the content of the body contains a series of key/value pairs that are created (most usually) by a form on the HTML side. You don't set the values using setHeader, as that won't place them in the content body.

So with your second test, the problem that you have here is that your client is not creating multiple key/value pairs, it only created one and that got mapped by default to the first argument in your method.

There are a couple of options you can use. First, you could change your method to accept only one input parameter, and then pass in a JSON string as you do in your second test. Once inside the method, you then parse the JSON string into an object that would allow access to the fields.

Another option is to define a class that represents the fields of the input types and make that the only input parameter. For example

class MyInput
{
    String str1;
    String str2;

    public MyInput() { }
      //  getters, setters
 }

@POST
@Consumes({"application/json"})
@Path("create/")
public void create(MyInput in){
System.out.println("value 1 = " + in.getStr1());
System.out.println("value 2 = " + in.getStr2());
}

Depending on the REST framework you are using it should handle the de-serialization of the JSON for you.

The last option is to construct a POST body that looks like:

str1=value1&str2=value2

then add some additional annotations to your server method:

public void create(@QueryParam("str1") String str1, 
                  @QueryParam("str2") String str2)

@QueryParam doesn't care if the field is in a form post or in the URL (like a GET query).

If you want to continue using individual arguments on the input then the key is generate the client request to provide named query parameters, either in the URL (for a GET) or in the body of the POST.

$(document).ready(my_function);

Or

$(document).ready(function () {
  // Function code here.
});

Or the shorter but less readable variant:

$(my_function);

All of these will cause my_function to be called after the DOM loads.

See the ready event documentation for more details.

Binds a function to be executed whenever the DOM is ready to be traversed and manipulated.

Edit:

To simulate a click, use the click() method without arguments:

$('#button').click();

From the docs:

Triggers the click event of each matched element. Causes all of the functions that have been bound to that click event to be executed.

To put it all together, the following code simulates a click when the document finishes loading:

$(function () {
  $('#button').click();
});

Just a note - Don't forget to enabled interaction on the view:

let tap = UITapGestureRecognizer(target: self, action: #selector(handleTap))

view.addGestureRecognizer(tap)

// view.userInteractionEnabled = true

self.view.addSubview(view)

very easy 1- install pakage :

pip install mouse

2- add library to project :

import mouse

3- use it for example :

mouse.right_click()

in this url describe all function that you can use it :

https://github.com/boppreh/mouse

Try adding the following attribute:

scrolling="no"

You don't need any configuration at all. However, the plugin offers a few options. This can be done as follows (default values shown):

testlogger {
    // pick a theme - mocha, standard, plain, mocha-parallel, standard-parallel or plain-parallel
    theme 'standard'

    // set to false to disable detailed failure logs
    showExceptions true

    // set to false to hide stack traces
    showStackTraces true

    // set to true to remove any filtering applied to stack traces
    showFullStackTraces false

    // set to false to hide exception causes
    showCauses true

    // set threshold in milliseconds to highlight slow tests
    slowThreshold 2000

    // displays a breakdown of passes, failures and skips along with total duration
    showSummary true

    // set to true to see simple class names
    showSimpleNames false

    // set to false to hide passed tests
    showPassed true

    // set to false to hide skipped tests
    showSkipped true

    // set to false to hide failed tests
    showFailed true

    // enable to see standard out and error streams inline with the test results
    showStandardStreams false

    // set to false to hide passed standard out and error streams
    showPassedStandardStreams true

    // set to false to hide skipped standard out and error streams
    showSkippedStandardStreams true

    // set to false to hide failed standard out and error streams
    showFailedStandardStreams true
}

I hope you will enjoy using it.

I had similar issue. Changed one of my table column from varchar2 to CLOB. I didn't needed to change any java code. I kept it as setString(..) only so no need to change set method as setClob() etch if you are using following versions ATLEAST of Oracle and jdbc driver.

I tried in In Oracle 11g and driver ojdbc6-11.2.0.4.jar

Position your <div> absolutely at the bottom and don't forget to give div.A a position: relative - http://jsfiddle.net/TTaMx/

    .A {
        position: relative;
        margin: 40px 0;
        height: 40px;
        width: 200px;
        background: #eee;
    }

    .A:after {
        content: " ";
        display: block;
        background: #c00;
        height: 29px;
        width: 100%;

        position: absolute;
        bottom: -29px;
    }?

Assuming you want them next to each other:

<form action="" class="form-inline">
    <div class="form-group">
        <input type="text" class="form-control" placeholder="MinVal">
    </div>
    <div class="form-group">    
         <input type="text" class="form-control" placeholder="MaxVal">   
    </div>
</form>

JSFiddle

Update Nr.1: Should you want to use .input-group with this example:

<form action="" class="form-inline">
    <div class="form-group">
        <div class="input-group">
          <span class="input-group-addon">@</span>
          <input type="text" class="form-control" placeholder="Username">
        </div>
    </div>
    <div class="form-group">    
        <div class="input-group">
          <input type="text" class="form-control">
          <span class="input-group-addon">.00</span>
        </div>
    </div>
</form>

JSFiddle

The class .input-group is there to extend inputs with buttons and such (directly attached). Checkboxes or radio buttons are possible as well. I don't think it works with two input fields though.

Update Nr. 2: With .form-horizontal the .form-group tag basically becomes a .row tag so you can use the column classes such as .col-sm-8:

<form action="" class="form-horizontal">
    <div class="form-group">
        <div class="col-sm-8">
            <input type="text" class="form-control" placeholder="MinVal">
        </div>
        <div class="col-sm-4">
            <input type="text" class="form-control" placeholder="MaxVal">
        </div>
    </div>
</form>

If you or some other fox who need to have link with Icon Image and text as link text beside the image see bellow code:

CSS

.linkWithImageIcon{

    Display:inline-block;
}
.MyLink{
  Background:#FF3300;
  width:200px;
  height:70px;
  vertical-align:top;
  display:inline-block; font-weight:bold;
} 

.MyLinkText{
  /*---The margin depends on how the image size is ---*/
  display:inline-block; margin-top:5px;
}

HTML

<a href="#" class="MyLink"><img src="./yourImageIcon.png" /><span class="MyLinkText">SIGN IN</span></a>

if you see the image the white portion is image icon and other is style this way you can create different buttons with any type of Icons you want to design

Sample from apache conf:

#Default value is 2 minutes
**Timeout 600**
ProxyRequests off
ProxyPass /app balancer://MyApp stickysession=JSESSIONID lbmethod=bytraffic nofailover=On
ProxyPassReverse /app balancer://MyApp
ProxyTimeout 600
<Proxy balancer://MyApp>
    BalancerMember http://node1:8080/ route=node1 retry=1 max=25 timeout=600
    .........
</Proxy>

In your link function, do this:

// link function
function (scope, element, attrs) {
  var myEl = angular.element(element[0].querySelector('.list-scrollable'));
}

Also, in your link function, don't name your scope variable using a $. That is an angular convention that is specific to built in angular services, and is not something that you want to use for your own variables.

The code to calculate factorial depends on your requirements.

1. Are you concerned about overflow?
2. What range of inputs will you have?
3. Is it more important for you to minimize size or time?
4. What are you going to do with the factorial?

Regarding points 1 and 4, it is often more useful to have a function to evaluate the log of the factorial directly rather than to have a function to evaluate factorial itself.

Here's a blog post that discusses these issues. Here is some C# code for computing log factorial that would be trivial to port to JavaScript. But it may not be best for your needs depending on your answers to the questions above.

to make it easier for you here is the code that i use :

w, h = image.shape
top=10
right=50
down=15
left=80
croped_image = image[top:((w-down)+top), right:((h-left)+right)]
plt.imshow(croped_image, cmap="gray")
plt.show()

When I run into such problem, I find FUSLOGVW tool very helpful. It is checking assembly binding information and logs it for you. Sometimes the libraries are missing, sometimes GAC has different versions that are being loaded. Sometimes the platform of referenced libraries is causing the problems. This tool makes it clear how the dependencies' bindings are being resolved and this may really help you to investigate/debug your problem.

I know this is a late response but I was facing a similar issue and I managed to solve it by using notifyDataSetChanged() in the right place.

So my situation was as follows.

I had to update a listview in an action bar tab (fragment) with contents returned from a completely different activity. Initially however, the listview would not reflect any changes. However, when I clicked another tab and then returned to the desired tab,the listview would be updated with the correct content from the other activity. So to solve this I used notifyDataSetChanged() of the action bar adapter in the code of the activity which had to return the data.

This is the code snippet which I used in the activity.

@Override
public boolean onOptionsItemSelected(MenuItem item) {

    switch (item.getItemId()) 
    {
        case R.id.action_new_forward:

            FragmentTab2.mListAdapter.notifyDataSetChanged();//this updates the adapter in my action bar tab
            Intent ina = new Intent(getApplicationContext(), MainActivity.class);
            ina.putExtra("stra", values1);
            startActivity(ina);// This is the code to start the parent activity of my action bar tab(fragment).
    }
}

This activity would return some data to FragmentTab2 and it would directly update my listview in FragmentTab2.

Hope someone finds this useful!

TL;DR Use GetProcessVersion.

All of these function are available in Windows XP [desktop apps | UWP apps].

GetProcessVersion uses a Process ID and returns 0 if the process of the given id is not running.

GetExitCodeProcess uses a Process handle and gives you the process exit code, if the code is STILL_ACTIVE (259) the process is still running so you could check if it is not STILL_ACTIVE (259) meaning that the process is not running. This is likely to work in basically every situation, unless the process exits with code 259.

WaitForSingleObject uses a Process handle with the SYNCHRONIZE access right and returns 0 if the process is not running. You should not specify INFINITE for the dwMilliseconds parameter because the function would not return until the process state became signaled(process is terminated).

I have faced and solved the tensor->ndarray conversion in the specific case of tensors representing (adversarial) images, obtained with cleverhans library/tutorials.

I think that my question/answer (here) may be an helpful example also for other cases.

I'm new with TensorFlow, mine is an empirical conclusion:

It seems that tensor.eval() method may need, in order to succeed, also the value for input placeholders. Tensor may work like a function that needs its input values (provided into feed_dict) in order to return an output value, e.g.

array_out = tensor.eval(session=sess, feed_dict={x: x_input})

Please note that the placeholder name is x in my case, but I suppose you should find out the right name for the input placeholder. x_input is a scalar value or array containing input data.

In my case also providing sess was mandatory.

My example also covers the matplotlib image visualization part, but this is OT.

Simple and Complete Solution working for me. Supports ASP.NET MVC 4 and 5 (Supports ASP.NET 4.0, 4.5, and 4.5.1)

Step 1: Install NuGet Package by "Install-Package reCAPTCH.MVC"

Step 2: Add your Public and Private key to your web.config file in appsettings section

<appSettings>
    <add key="ReCaptchaPrivateKey" value=" -- PRIVATE_KEY -- " />
    <add key="ReCaptchaPublicKey" value=" -- PUBLIC KEY -- " />
</appSettings>  

You can create an API key pair for your site at https://www.google.com/recaptcha/intro/index.html and click on Get reCAPTCHA at top of the page

Step 3: Modify your form to include reCaptcha

@using reCAPTCHA.MVC
@using (Html.BeginForm())
{
    @Html.Recaptcha()
    @Html.ValidationMessage("ReCaptcha")
    <input type="submit" value="Register" />
}

Step 4: Implement the Controller Action that will handle the form submission and Captcha validation

[CaptchaValidator(
PrivateKey = "your private reCaptcha Google Key",
ErrorMessage = "Invalid input captcha.",
RequiredMessage = "The captcha field is required.")]
public ActionResult MyAction(myVM model)
{
    if (ModelState.IsValid) //this will take care of captcha
    {
    }
}

OR

public ActionResult MyAction(myVM model, bool captchaValid)
{
    if (captchaValid) //manually check for captchaValid 
    {
    }
}

If you're targeting at or above iOS 8 or OS X 10.10, this just got a lot easier. The new NSDateComponentsFormatter class allows you to convert a given NSTimeInterval from its value in seconds to a localized string to show the user. For example:

Objective-C

NSTimeInterval interval = 326.4;

NSDateComponentsFormatter *componentFormatter = [[NSDateComponentsFormatter alloc] init];

componentFormatter.unitsStyle = NSDateComponentsFormatterUnitsStylePositional;
componentFormatter.zeroFormattingBehavior = NSDateComponentsFormatterZeroFormattingBehaviorDropAll;

NSString *formattedString = [componentFormatter stringFromTimeInterval:interval];
NSLog(@"%@",formattedString); // 5:26

Swift

let interval = 326.4

let componentFormatter = NSDateComponentsFormatter()

componentFormatter.unitsStyle = .Positional
componentFormatter.zeroFormattingBehavior = .DropAll

if let formattedString = componentFormatter.stringFromTimeInterval(interval) {
    print(formattedString) // 5:26
}

NSDateCompnentsFormatter also allows for this output to be in longer forms. More info can be found in NSHipster's NSFormatter article. And depending on what classes you're already working with (if not NSTimeInterval), it may be more convenient to pass the formatter an instance of NSDateComponents, or two NSDate objects, which can be done as well via the following methods.

Objective-C

NSString *formattedString = [componentFormatter stringFromDate:<#(NSDate *)#> toDate:<#(NSDate *)#>];
NSString *formattedString = [componentFormatter stringFromDateComponents:<#(NSDateComponents *)#>];

Swift

if let formattedString = componentFormatter.stringFromDate(<#T##startDate: NSDate##NSDate#>, toDate: <#T##NSDate#>) {
    // ...
}

if let formattedString = componentFormatter.stringFromDateComponents(<#T##components: NSDateComponents##NSDateComponents#>) {
    // ...
}

I almost always just use overflow:hidden on my text-elements in those situations, it often works like a charm ;)

.post-container {
 margin: 20px 20px 0 0;
 border:5px solid #333;
}
.post-thumb img {
 float: left;
}
.post-content {
 overflow:hidden;
}

Since you've got an array, what you really want is Array#slice, not split.

rest = ex.slice(1 .. -1)
# or
rest = ex[1 .. -1]

I'm going to answer the literal question: no, there isn't a good reason you see VARCHAR(255) used so often (there are indeed reasons, as discussed in the other answers, just not good ones). You won't find many examples of projects that have failed catastrophically because the architect chose VARCHAR(300) instead of VARCHAR(255). This would be an issue of near-total insignificance even if you were talking about CHAR instead of VARCHAR.

The easiest way to change the background color of the jumbotron

If you want to change the background color of your jumbotron, then for that you can apply a background color to it using one of your custom class.

HTML Code:

<div class="jumbotron myclass">   
    <h1>My Heading</h1>
    <p>Lorem Ipsum is simply dummy text of the printing and typesetting industry.</p>
</div> 

CSS Code:

<style>
    .myclass{
        background-color: red;
    }
</style>

Be careful,

jQuery.validator.addMethod("lettersonly", function(value, element) 
{
return this.optional(element) || /^[a-z," "]+$/i.test(value);
}, "Letters and spaces only please"); 

[a-z, " "] by adding the comma and quotation marks, you are allowing spaces, commas and quotation marks into the input box.

For spaces + text, just do this:

jQuery.validator.addMethod("lettersonly", function(value, element) 
{
return this.optional(element) || /^[a-z ]+$/i.test(value);
}, "Letters and spaces only please");

[a-z ] this allows spaces aswell as text only.

............................................................................

also the message "Letters and spaces only please" is not required, if you already have a message in messages:

messages:{
        firstname:{
        required: "Enter your first name",
        minlength: jQuery.format("Enter at least (2) characters"),
        maxlength:jQuery.format("First name too long more than (80) characters"),
        lettersonly:jQuery.format("letters only mate")
        },

Never and ever for the sake of your own good, name the folders or files with symbols like "-" or "_". If you did so, you may face few issues. like mine, say, though your command for importing is correct, you wont be able to successfully import the desired files which are available inside such named folders.

Invalid Folder namings as follows:

• Generic-Classes-Folder
• Generic_Classes_Folder

valid Folder namings for above:

• GenericClassesFolder or Genericclassesfolder or genericClassesFolder (or like this without any spaces or special symbols among the words)

What mistake I did:

consider the file structure.

Parent
   . __init__.py
   . Setup
     .. __init__.py
     .. Generic-Class-Folder
        ... __init__.py
        ... targetClass.py
   . Check
     .. __init__.py
     .. testFile.py

What I wanted to do?

• from testFile.py, I wanted to import the 'targetClass.py' file inside the Generic-Class-Folder file to use the function named "functionExecute" in 'targetClass.py' file

What command I did?

• from 'testFile.py', wrote command, from Core.Generic-Class-Folder.targetClass import functionExecute
• Got errors like SyntaxError: invalid syntax

Tried many searches and viewed many stackoverflow questions and unable to decide what went wrong. I cross checked my files multiple times, i used __init__.py file, inserted environment path and hugely worried what went wrong......

And after a long long long time, i figured this out while talking with a friend of mine. I am little stupid to use such naming conventions. I should never use space or special symbols to define a name for any folder or file. So, this is what I wanted to convey. Have a good day!

(sorry for the huge post over this... just letting my frustrations go.... :) Thanks!)

Does an implicit conversion occur between Task<> and int?

Nope. This is just part of how async/await works.

Any method declared as async has to have a return type of:

• void (avoid if possible)
• Task (no result beyond notification of completion/failure)
• Task<T> (for a logical result of type T in an async manner)

The compiler does all the appropriate wrapping. The point is that you're asynchronously returning urlContents.Length - you can't make the method just return int, as the actual method will return when it hits the first await expression which hasn't already completed. So instead, it returns a Task<int> which will complete when the async method itself completes.

Note that await does the opposite - it unwraps a Task<T> to a T value, which is how this line works:

string urlContents = await getStringTask;

... but of course it unwraps it asynchronously, whereas just using Result would block until the task had completed. (await can unwrap other types which implement the awaitable pattern, but Task<T> is the one you're likely to use most often.)

This dual wrapping/unwrapping is what allows async to be so composable. For example, I could write another async method which calls yours and doubles the result:

public async Task<int> AccessTheWebAndDoubleAsync()
{
    var task = AccessTheWebAsync();
    int result = await task;
    return result * 2;
}

(Or simply return await AccessTheWebAsync() * 2; of course.)

There is no difference at all!

1) git checkout -b branch origin/branch

If there is no --track and no --no-track, --track is assumed as default. The default can be changed with the setting branch.autosetupmerge.

In effect, 1) behaves like git checkout -b branch --track origin/branch.

2) git checkout --track origin/branch

“As a convenience”, --track without -b implies -b and the argument to -b is guessed to be “branch”. The guessing is driven by the configuration variable remote.origin.fetch.

In effect, 2) behaves like git checkout -b branch --track origin/branch.

As you can see: no difference.

But it gets even better:

3) git checkout branch

is also equivalent to git checkout -b branch --track origin/branch if “branch” does not exist yet but “origin/branch” does¹.

All three commands set the “upstream” of “branch” to be “origin/branch” (or they fail).

Upstream is used as reference point of argument-less git status, git push, git merge and thus git pull (if configured like that (which is the default or almost the default)).

E.g. git status tells you how far behind or ahead you are of upstream, if one is configured.

git push is configured to push the current branch upstream by default² since git 2.0.

^{1 ...and if “origin” is the only remote having “branch”
2 the default (named “simple”) also enforces for both branch names to be equal}

Darin Dimitrov's answer is correct. Just an addition:

Response.AppendHeader("Content-Disposition", cd.ToString()); may cause the browser to fail rendering the file if your response already contains a "Content-Disposition" header. In that case, you may want to use:

Response.Headers.Add("Content-Disposition", cd.ToString());

• Create a subdirectory named lib.
• Create an empty file named lib\__init__.py.

• In lib\BoxTime.py, write a function foo() like this:

  def foo():
      print "foo!"
  

• In your client code in the directory above lib, write:

  from lib import BoxTime
  BoxTime.foo()
  

• Run your client code. You will get:

  foo!
  

Much later -- in linux, it would look like this:

% cd ~/tmp
% mkdir lib
% touch lib/__init__.py
% cat > lib/BoxTime.py << EOF
heredoc> def foo():
heredoc>     print "foo!"
heredoc> EOF
% tree lib

There is also a simple answer for defining specific styles that are only going to be applied to that specific button and you can have Jquery declare element style when declaring the dialog:

id: "button-delete",
text: "Delete",
style: "display: none;",
click: function () {}

after doing that here is what the html shows:

doing this allows you to set it, but it is not necessarily easy to change using jquery later.

Determining of root cause is not an issue since Go 1.8; field name now is shown in the error message:

json: cannot unmarshal object into Go struct field Comment.author of type string

Since "$(this).parent().index();" and "$(this).parent('table').index();" don't work for me, I use this code instead:

$('td').click(function(){
   var row_index = $(this).closest("tr").index();
   var col_index = $(this).index();
});

You can do that with a regular expression but probably you'll want to some else. For example use several regexp and combine them in a if clause.

You can enumerate all possible permutations with a standard regexp, like this (matches a, b and c in any order):

(abc)|(bca)|(acb)|(bac)|(cab)|(cba)

However, this makes a very long and probably inefficient regexp, if you have more than couple terms.

If you are using some extended regexp version, like Perl's or Java's, they have better ways to do this. Other answers have suggested using positive lookahead operation.

On Fedora 28, just pay attention to the line

security.useSystemPropertiesFile=true

of the java.security file, found at:

$(dirname $(readlink -f $(which java)))/../lib/security/java.security

Fedora 28 introduced external file of disabledAlgorithms control at

/etc/crypto-policies/back-ends/java.config

You can edit this external file or you can exclude it from java.security by setting

security.useSystemPropertiesFile=false

Well, did you DO what the error says? You go to some length telling about installation, but what about the obvious?

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

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

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

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

The problem here is that the length of your array is undefined, and this confuses VBA if the array is explicitly defined as a string. Variants, however, seem to be able to resize as needed (because they hog a bunch of memory, and people generally avoid them for a bunch of reasons).

The following code works just fine, but it's a bit manual compared to some of the other languages out there:

Dim SomeArray(3) As String

SomeArray(0) = "Zero"
SomeArray(1) = "One"
SomeArray(2) = "Two"
SomeArray(3) = "Three"

For most of the people still receiving the error after fixing project properties, you probably installed Java 7 SDK when setting up your environment, but it is not currently supported for Android development.

As the error message sais, you should have installed Java 5.0 or 6.0, but Java 7 was found.

If you fix project properties without first installing Java 5 or 6, you will see the same error again.

• So first, ensure you have Java SDK 5 or 6 installed, or install it.
• Check your environment variable (JAVA_HOME) is pointing to SDK 5/6.

And then:

• Check that Eclipse is using SDK 5/6 by default (Window => Prefs. => Java => Compiler
• Disable Project Specific Settings (Project Properties => Java Compiler)
• Fix Project Properties

OR

• Leave Eclipse using JDK 7 by default.
• Enable Project Specific Settings (Project Properties => Java Compiler)
• Select Compiler Compliance 1.5 or 1.6 (Project Properties => Java Compiler)

There's a new API introduced in API 19 (KitKat): ActivityManager.clearApplicationUserData().

I highly recommend using it in new applications:

import android.os.Build.*;
if (VERSION_CODES.KITKAT <= VERSION.SDK_INT) {
    ((ActivityManager)context.getSystemService(ACTIVITY_SERVICE))
            .clearApplicationUserData(); // note: it has a return value!
} else {
    // use old hacky way, which can be removed
    // once minSdkVersion goes above 19 in a few years.
}

If you don't want the hacky way you can also hide the button on the UI, so that functionality is just not available on old phones.

Knowledge of this method is mandatory for anyone using android:manageSpaceActivity.

Whenever I use this, I do so from a manageSpaceActivity which has android:process=":manager". There, I manually kill any other processes of my app. This allows me to let a UI stay running and let the user decide where to go next.

private static void killProcessesAround(Activity activity) throws NameNotFoundException {
    ActivityManager am = (ActivityManager)activity.getSystemService(Context.ACTIVITY_SERVICE);
    String myProcessPrefix = activity.getApplicationInfo().processName;
    String myProcessName = activity.getPackageManager().getActivityInfo(activity.getComponentName(), 0).processName;
    for (ActivityManager.RunningAppProcessInfo proc : am.getRunningAppProcesses()) {
        if (proc.processName.startsWith(myProcessPrefix) && !proc.processName.equals(myProcessName)) {
            android.os.Process.killProcess(proc.pid);
        }
    }
}

The current answer can be simplified to...

@Component({
  ...
  template: '<child [myCallback]="theCallback"></child>',
  directives: [ChildComponent]
})
export class ParentComponent{
  public theCallback(){
    ...
  }
}

@Component({...})
export class ChildComponent{
  //This will be bound to the ParentComponent.theCallback
  @Input()
  public myCallback: Function; 
  ...
}

> is not in the documentation.

< is for one-way binding.

@ binding is for passing strings. These strings support {{}} expressions for interpolated values.

= binding is for two-way model binding. The model in parent scope is linked to the model in the directive's isolated scope.

& binding is for passing a method into your directive's scope so that it can be called within your directive.

When we are setting scope: true in directive, Angular js will create a new scope for that directive. That means any changes made to the directive scope will not reflect back in parent controller.

        nameBuilder.append("'").append(n.replace("'", "\\'")).append("',");
        // can also do the following
        // nameBuilder.append("'").append(n.replace("'", "''")).append("',");
    }

    nameBuilder.deleteCharAt(nameBuilder.length() - 1);

    return nameBuilder.toString();
} else {
    return "";
}

Better to use a vbs as you indicated

1. Create a simple vbs, which is a text file with a .vbs extension (see sample code below)
2. Use the Task Scheduler to run the vbs
3. Use the vbs to open the workbook at the scheduled time and then either:
   • use the Private Sub Workbook_Open() event in the ThisWorkbook module to run code when the file is opened
   • more robustly (as macros may be disabled on open), use Application.Run in the vbs to run the macro

See this example of the later approach at Running Excel on Windows Task Scheduler

sample vbs

Dim ObjExcel, ObjWB
Set ObjExcel = CreateObject("excel.application")
'vbs opens a file specified by the path below
Set ObjWB = ObjExcel.Workbooks.Open("C:\temp\rod.xlsm")
'either use the Workbook Open event (if macros are enabled), or Application.Run

ObjWB.Close False
ObjExcel.Quit
Set ObjExcel = Nothing

First run your project from Xcode then try to run from command line. That was the issue for me.

Use RVM (Ruby Version Manager) to install and manage any versions of Ruby. You can have multiple versions of Ruby installed on the machine and you can easily select the one you want.

To install RVM type into terminal:

\curl -sSL https://get.rvm.io | bash -s stable

And let it work. After that you will have RVM along with Ruby installed.

Generate a form on Page B with all the required data and action set to Page C and submit it with JavaScript on page load. Your data will be sent to Page C without much hassle to the user.

This is the only way to do it. A redirect is a 303 HTTP header that you can read up on http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html, but I'll quote some of it:

The response to the request can be found under a different URI and SHOULD be retrieved using a GET method on that resource. This method exists primarily to allow the output of a POST-activated script to redirect the user agent to a selected resource. The new URI is not a substitute reference for the originally requested resource. The 303 response MUST NOT be cached, but the response to the second (redirected) request might be cacheable.

The only way to achieve what you're doing is with a intermediate page that sends the user to Page C. Here's a small/simple snippet on how you can achieve that:

<form id="myForm" action="Page_C.php" method="post">
<?php
    foreach ($_POST as $a => $b) {
        echo '<input type="hidden" name="'.htmlentities($a).'" value="'.htmlentities($b).'">';
    }
?>
</form>
<script type="text/javascript">
    document.getElementById('myForm').submit();
</script>

You should also have a simple "confirm" form inside a noscript tag to make sure users without Javascript will be able to use your service.

The procedure presented below gives an example of parsing XML with VBA using the XML DOM objects. Code is based on a beginners guide of the XML DOM.

Public Sub LoadDocument()
    Dim xDoc As MSXML.DOMDocument
    Set xDoc = New MSXML.DOMDocument
    xDoc.validateOnParse = False
    If xDoc.Load("C:\My Documents\sample.xml") Then
        ' The document loaded successfully.
        ' Now do something intersting.
        DisplayNode xDoc.childNodes, 0
    Else
        ' The document failed to load.
        ' See the previous listing for error information.
    End If
End Sub

Public Sub DisplayNode(ByRef Nodes As MSXML.IXMLDOMNodeList, _
   ByVal Indent As Integer)

   Dim xNode As MSXML.IXMLDOMNode
   Indent = Indent + 2

   For Each xNode In Nodes
      If xNode.nodeType = NODE_TEXT Then
         Debug.Print Space$(Indent) & xNode.parentNode.nodeName & _
            ":" & xNode.nodeValue
      End If

      If xNode.hasChildNodes Then
         DisplayNode xNode.childNodes, Indent
      End If
   Next xNode
End Sub

Nota Bene - This initial answer shows the simplest possible thing I could imagine (at the time I was working on a very specific issue) . Naturally using the XML facilities built into the VBA XML Dom would be much better. See the updates above.

Original Response

I know this is a very old post but I wanted to share my simple solution to this complicated question. Primarily I've used basic string functions to access the xml data.

This assumes you have some xml data (in the temp variable) that has been returned within a VBA function. Interestingly enough one can also see how I am linking to an xml web service to retrieve the value. The function shown in the image also takes a lookup value because this Excel VBA function can be accessed from within a cell using = FunctionName(value1, value2) to return values via the web service into a spreadsheet.

openTag = ""
closeTag = "" 

' Locate the position of the enclosing tags
startPos = InStr(1, temp, openTag)
endPos = InStr(1, temp, closeTag)
startTagPos = InStr(startPos, temp, ">") + 1
' Parse xml for returned value
Data = Mid(temp, startTagPos, endPos - startTagPos)

Follow below steps to login to your ubuntu VM running in virtual box from the host machine using putty (Without port forwarding):

1. On Virtualbox manager select the vm, click on settings icon. Then go Networks and enable two adaptors as below:

   • Adaptor 1 (For internet access): Attached to -> NAT, Advanced -> Check the cable connected.
   • Adaptor 2: Attached to -> Host only adaptor, Advanced -> Check the cable connected and Promiscuous mode -> Allow all.

2. Start the ubuntu vm.

3. Login to the VM as root.

4. Edit the file '/etc/network/interfaces' as below and save it:

   auto lo
   iface lo inet loopback
   
   auto eth0
   iface eth0 inet dhcp
   
   auto eth1
   iface eth1 inet dhcp
   

5. Restart the VM.

6. Login to the VM and run below command to check the IP allocated to eth1:

   ifconfig
   

7. Use this IP to open putty session for the VM.

Command line usage:

for /f %f in ('dir /b c:\') do echo %f

Batch file usage:

for /f %%f in ('dir /b c:\') do echo %%f

Update: if the directory contains files with space in the names, you need to change the delimiter the for /f command is using. for example, you can use the pipe char.

for /f "delims=|" %%f in ('dir /b c:\') do echo %%f

Update 2: (quick one year and a half after the original answer :-)) If the directory name itself has a space in the name, you can use the usebackq option on the for:

for /f "usebackq delims=|" %%f in (`dir /b "c:\program files"`) do echo %%f

And if you need to use output redirection or command piping, use the escape char (^):

for /f "usebackq delims=|" %%f in (`dir /b "c:\program files" ^| findstr /i microsoft`) do echo %%f

chmod a+x modifies the argument's mode while chmod 755 sets it. Try both variants on something that has full or no permissions and you will notice the difference.

Our HTML:

<div id="addnew">
    <input type="text" id="id">
    <input type="text" id="content">
    <input type="button" value="Add" id="submit">
</div>

<div id="check">
    <input type="text" id="input">
    <input type="button" value="Search" id="search">
</div>

JS (writing to the txt file):

function writeToFile(d1, d2){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 8, false, 0);
    fh.WriteLine(d1 + ',' + d2);
    fh.Close();
}
var submit = document.getElementById("submit");
submit.onclick = function () {
    var id      = document.getElementById("id").value;
    var content = document.getElementById("content").value;
    writeToFile(id, content);
}

checking a particular row:

function readFile(){
    var fso = new ActiveXObject("Scripting.FileSystemObject");
    var fh = fso.OpenTextFile("data.txt", 1, false, 0);
    var lines = "";
    while (!fh.AtEndOfStream) {
        lines += fh.ReadLine() + "\r";
    }
    fh.Close();
    return lines;
}
var search = document.getElementById("search");
search.onclick = function () {
    var input   = document.getElementById("input").value;
    if (input != "") {
        var text    = readFile();
        var lines   = text.split("\r");
        lines.pop();
        var result;
        for (var i = 0; i < lines.length; i++) {
            if (lines[i].match(new RegExp(input))) {
                result = "Found: " + lines[i].split(",")[1];
            }
        }
        if (result) { alert(result); }
        else { alert(input + " not found!"); }
    }
}

Put these inside a .hta file and run it. Tested on W7, IE11. It's working. Also if you want me to explain what's going on, say so.

To get the folder of a file just use:

os.path.dirname(path) 

To get a folder up just use os.path.dirname again

os.path.dirname(os.path.dirname(path))

You might want to check if __file__ is a symlink:

if os.path.islink(__file__): path = os.readlink (__file__)

AFAIK, there 2 thing in every recursion function :

1. There is always a stop condition which is :

   if ((null == str) || (str.length() <= 1)) { return str; }

2. Recursion use the stack memory which use LIFO mechanism that's why the revert happen.

I had the same problem, you can solve it by:

@Override
protected void onPostExecute(MyResult result) {
    try {
        if ((this.mDialog != null) && this.mDialog.isShowing()) {
            this.mDialog.dismiss();
        }
    } catch (final IllegalArgumentException e) {
        // Handle or log or ignore
    } catch (final Exception e) {
        // Handle or log or ignore
    } finally {
        this.mDialog = null;
    }  
}

if you want to get the week number with the year use: "%Y-W%V":

e.g    yearAndweeks <- strftime(dates, format = "%Y-W%V")

so

> strftime(c("2014-03-16", "2014-03-17","2014-03-18", "2014-01-01"), format = "%Y-W%V")

becomes:

[1] "2014-W11" "2014-W12" "2014-W12" "2014-W01"

Option 1: Use a nullable DateTime?

Option 2: Use DateTime.MinValue

Personally, I'd prefer option 1.

A double quote character (") can be escaped as ", but here's the rest of the story...

Double quote character must be escaped in this context:

• In XML attributes delimited by double quotes:

  <EscapeNeeded name="Pete &quot;Maverick&quot; Mitchell"/>
  

Double quote character need not be escaped in most contexts:

• In XML textual content:

  <NoEscapeNeeded>He said, "Don't quote me."</NoEscapeNeeded>
  

• In XML attributes delimited by single quotes ('):

  <NoEscapeNeeded name='Pete "Maverick" Mitchell'/>
  

  Similarly, (') require no escaping if (") are used for the attribute value delimiters:

  <NoEscapeNeeded name="Pete 'Maverick' Mitchell"/>

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

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

git pull origin master

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

1) How to check remote's name

git remote -v

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

git branch -r

You can use ComboBox, then point your mouse to the upper arrow facing right, it will unfold a box called ComboBox Tasks and in there you can go ahead and edit your items or fill in the items / strings one per line. This should be the easiest.

Make sure that you're using the Sun JVM to run Eclipse.

On Linux, particularly Ubuntu, Eclipse is installed by default to use the open source GCJ, which has drastically poorer performance. Use update-alternatives --config java to switch to the Sun JVM to greatly improve UI snappiness in Eclipse.

wget is capable of doing what you are asking. Just try the following:

wget -p -k http://www.example.com/

The -p will get you all the required elements to view the site correctly (css, images, etc). The -k will change all links (to include those for CSS & images) to allow you to view the page offline as it appeared online.

From the Wget docs:

‘-k’
‘--convert-links’
After the download is complete, convert the links in the document to make them
suitable for local viewing. This affects not only the visible hyperlinks, but
any part of the document that links to external content, such as embedded images,
links to style sheets, hyperlinks to non-html content, etc.

Each link will be changed in one of the two ways:

    The links to files that have been downloaded by Wget will be changed to refer
    to the file they point to as a relative link.

    Example: if the downloaded file /foo/doc.html links to /bar/img.gif, also
    downloaded, then the link in doc.html will be modified to point to
    ‘../bar/img.gif’. This kind of transformation works reliably for arbitrary
    combinations of directories.

    The links to files that have not been downloaded by Wget will be changed to
    include host name and absolute path of the location they point to.

    Example: if the downloaded file /foo/doc.html links to /bar/img.gif (or to
    ../bar/img.gif), then the link in doc.html will be modified to point to
    http://hostname/bar/img.gif. 

Because of this, local browsing works reliably: if a linked file was downloaded,
the link will refer to its local name; if it was not downloaded, the link will
refer to its full Internet address rather than presenting a broken link. The fact
that the former links are converted to relative links ensures that you can move
the downloaded hierarchy to another directory.

Note that only at the end of the download can Wget know which links have been
downloaded. Because of that, the work done by ‘-k’ will be performed at the end
of all the downloads. 

Typical usage for conditional removal of error from Model State:

1. Make conditional first part of controller action
2. Perform logic to remove error from ModelState
3. Do the rest of the existing logic (typically Model State validation, then everything else)

Example:

public ActionResult MyAction(MyViewModel vm)
{
    // perform conditional test
    // if true, then remove from ModelState (e.g. ModelState.Remove("MyKey")

    // Do typical model state validation, inside following if:
    //     if (!ModelState.IsValid)

    // Do rest of logic (e.g. fetching, saving

In your example, keep everything as is and add the logic suggested to your Controller's Action. I'm assuming your ViewModel passed to the controller action has the Person and Senior Person objects with data populated in them from the UI.

Thanks a lot this note was very useful for me! Was able to send the variable defined under /group_var/vars in the ansible playbook as indicated below.

tasks:
- name: check service account password expiry
- command:

sh /home/monit/get_ldap_attr.sh {{ item }} {{ LDAP_AUTH_USR }}

This code works

filter: alpha(opacity = 50); zoom:1;

You need to add zoom property for it to work :)

The most efficient and easy way:

list(data_set.to_records())

You can filter the columns you need before this call.

This may be a good explanation example

CREATE TABLE employees (
id INTEGER NOT NULL PRIMARY KEY,
managerId INTEGER REFERENCES employees(id), 
name VARCHAR(30) NOT NULL
);

INSERT INTO employees(id, managerId, name) VALUES(1, NULL, 'John');
INSERT INTO employees(id, managerId, name) VALUES(2, 1, 'Mike');

-- Explanation: -- In this example. -- John is Mike's manager. Mike does not manage anyone. -- Mike is the only employee who does not manage anyone.

An example of copy row from dataGridView and added a new row in The same dataGridView:

DataTable Dt = new DataTable();
Dt.Columns.Add("Column1");
Dt.Columns.Add("Column2");

DataRow dr = Dt.NewRow();
DataGridViewRow dgvR = (DataGridViewRow)dataGridView1.CurrentRow;
dr[0] = dgvR.Cells[0].Value; 
dr[1] = dgvR.Cells[1].Value;              

Dt.Rows.Add(dR);
dataGridView1.DataSource = Dt;

I built on sabithpocker's idea and made a more generalized version that lets you control more than one selectbox from a given trigger.

I assigned the selectboxes I wanted to be controlled the classname "switchable," and cloned them all like this:

$j(this).data('options',$j('select.switchable option').clone());

and used a specific naming convention for the switchable selects, which could also translate into classes. In my case, "category" and "issuer" were the select names, and "category_2" and "issuer_1" the class names.

Then I ran an $.each on the select.switchable groups, after making a copy of $(this) for use inside the function:

var that = this;
$j("select.switchable").each(function() { 
    var thisname = $j(this).attr('name');
    var theseoptions = $j(that).data('options').filter( '.' + thisname + '_' + id );
    $j(this).html(theseoptions);
});     

By using a classname on the ones you want to control, the function will safely ignore other selects elsewhere on the page (such as the last one in the example on Fiddle).

Here's a Fiddle with the complete code:

I'm trying to use variables and settings from that file, not to invoke a separate process.

Well, simply importing the file with import filename (minus .py, needs to be in the same directory or on your PYTHONPATH) will run the file, making its variables, functions, classes, etc. available in the filename.variable namespace.

So if you have cheddar.py with the variable spam and the function eggs – you can import them with import cheddar, access the variable with cheddar.spam and run the function by calling cheddar.eggs()

If you have code in cheddar.py that is outside a function, it will be run immediately, but building applications that runs stuff on import is going to make it hard to reuse your code. If a all possible, put everything inside functions or classes.

solution is easy:

replace

 mask = (50  < df['heart rate'] < 101 &
            140 < df['systolic blood pressure'] < 160 &
            90  < df['dyastolic blood pressure'] < 100 &
            35  < df['temperature'] < 39 &
            11  < df['respiratory rate'] < 19 &
            95  < df['pulse oximetry'] < 100
            , "excellent", "critical")

by

mask = ((50  < df['heart rate'] < 101) &
        (140 < df['systolic blood pressure'] < 160) &
        (90  < df['dyastolic blood pressure'] < 100) &
        (35  < df['temperature'] < 39) &
        (11  < df['respiratory rate'] < 19) &
        (95  < df['pulse oximetry'] < 100)
        , "excellent", "critical")

You can find the full list here.

• \t Insert a tab in the text at this point.
• \b Insert a backspace in the text at this point.
• \n Insert a newline in the text at this point.
• \r Insert a carriage return in the text at this point.
• \f Insert a formfeed in the text at this point.
• \' Insert a single quote character in the text at this point.
• \" Insert a double quote character in the text at this point.
• \\ Insert a backslash character in the text at this point.

Since you don't state if the form can resize or not there is an easy way if you don't care about resizing (if you do care, go with Mitch Wheats solution):

Select the control -> Format (menu option) -> Center in Window -> Horizontally or Vertically

I recommend using a LifecycleObserver which is part of the Handling Lifecycles with Lifecycle-Aware Components of Android Jetpack.

I want to open and close the Keyboard when the Fragment/Activity appears. Firstly, define two extension functions for the EditText. You can put them anywhere in your project:

fun EditText.showKeyboard() {
    requestFocus()
    val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.showSoftInput(this, InputMethodManager.SHOW_IMPLICIT)
}

fun EditText.hideKeyboard() {
    val imm = context.getSystemService(Context.INPUT_METHOD_SERVICE) as InputMethodManager
    imm.hideSoftInputFromWindow(this.windowToken, 0)
}

Then define a LifecycleObserver which opens and closes the keyboard when the Activity/Fragment reaches onResume() or onPause:

class EditTextKeyboardLifecycleObserver(private val editText: WeakReference<EditText>) :
    LifecycleObserver {

    @OnLifecycleEvent(Lifecycle.Event.ON_RESUME)
    fun openKeyboard() {
        editText.get()?.postDelayed({ editText.get()?.showKeyboard() }, 100)
    }

    @OnLifecycleEvent(Lifecycle.Event.ON_PAUSE)
    fun closeKeyboard() {
        editText.get()?.hideKeyboard()
    }
}

Then add the following line to any of your Fragments/Activities, you can reuse the LifecycleObserver any times. E.g. for a Fragment:

override fun onViewCreated(view: View, savedInstanceState: Bundle?) {
        super.onViewCreated(view, savedInstanceState)

    // inflate the Fragment layout

    lifecycle.addObserver(EditTextKeyboardLifecycleObserver(WeakReference(myEditText)))

    // do other stuff and return the view

}

Here's an efficient option that doesn't use the clipboard.

Sub transposeAndPasteRow(rowToCopy As Range, pasteTarget As Range)
    pasteTarget.Resize(rowToCopy.Columns.Count) = Application.WorksheetFunction.Transpose(rowToCopy.Value)
End Sub

Use it like this.

Sub test()
    Call transposeAndPasteRow(Worksheets("Sheet1").Range("A1:A5"), Worksheets("Sheet2").Range("A1"))
End Sub

Set the width of the <td>s to 50px and then add your <td> + another fake <td>

Fiddle.

table tr td:empty {_x000D_
  width: 50px;_x000D_
}_x000D_
  _x000D_
table tr td {_x000D_
  padding-top: 10px;_x000D_
  padding-bottom: 10px;_x000D_
}

<table>_x000D_
  <tr>_x000D_
    <td>First Column</td>_x000D_
    <td></td>_x000D_
    <td>Second Column</td>_x000D_
    <td></td>_x000D_
    <td>Third Column</td>_x000D_
  </tr>_x000D_
</table>

Code Explained:

The first CSS rule checks for empty td's and give them a width of 50px then the second rule give the padding of top and bottom to all the td's.

the default text size of the textview

if you not used any of the below

TextAppearance.Small

TextAppearance.Medium

TextAppearance.Large

then the default size is 14sp

I like to use Optional and streams to have a net and clear solution, i use the below code to iterate over a directory. the below cases are handled by the code:

1. handle the case of empty directory
2. Laziness

but as mentioned by others, you still have to pay attention for outOfMemory in case you have huge folders

    File directoryFile = new File("put your path here");
    Stream<File> files = Optional.ofNullable(directoryFile// directoryFile
                                                          .listFiles(File::isDirectory)) // filter only directories(change with null if you don't need to filter)
                                 .stream()
                                 .flatMap(Arrays::stream);// flatmap from Stream<File[]> to Stream<File>

WOFF 2.0, based on the Brotli compression algorithm and other improvements over WOFF 1.0 giving more than 30 % reduction in file size, is supported in Chrome, Opera, and Firefox.

http://en.wikipedia.org/wiki/Web_Open_Font_Format http://en.wikipedia.org/wiki/Brotli

http://sth.name/2014/09/03/Speed-up-webfonts/ has an example on how to use it.

Basically you add a src url to the woff2 file and specify the woff2 format. It is important to have this before the woff-format: the browser will use the first format that it supports.

This can be solved with an assignment tag:

from django import template

register = template.Library()

@register.assignment_tag
def query(qs, **kwargs):
    """ template tag which allows queryset filtering. Usage:
          {% query books author=author as mybooks %}
          {% for book in mybooks %}
            ...
          {% endfor %}
    """
    return qs.filter(**kwargs)

You can use the timestamp plugin of mongoose-troop to add this behavior to any schema.

The question is how to call a C function from Python, if I understood correctly. Then the best bet are Ctypes (BTW portable across all variants of Python).

>>> from ctypes import *
>>> libc = cdll.msvcrt
>>> print libc.time(None)

For a detailed guide you may want to refer to my blog article.

Why don't you try this

for(int i=0; i < dt.Rows.Count; i++)
{
  // u can use here the i
}

         File file = ...
         byte[] data = ...
         try{
            FileOutputStream fos = FileOutputStream(file);
            fos.write(data);
            fos.flush();
            fos.close();
         }catch(Exception e){
          }

but if the bytes array length is more than 1024 you should use loop to write the data.

An alternative to System.Diagnostics.StackTrace is to use System.Environment.StackTrace which returns a string-representation of the stacktrace.

Another useful option is to use the $CALLER and $CALLSTACK debugging variables in Visual Studio since this can be enabled run-time without rebuilding the application.

Another elegant solution.

String myString = "\nLogbasex\n";
myString = org.apache.commons.lang3.StringUtils.strip(myString, "\n");

Set in your .htaccess file

RewriteEngine On
RewriteCond %{HTTP_HOST} !^www.
RewriteRule ^(.*)$ https://www.%{HTTP_HOST}/$1 [R=301,L]
RewriteCond %{HTTPS} !=on
RewriteRule ^ https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

Here seems to be an even better answer with 'in' clause that allows for multiple keys for the join:

update fp_active set STATE='E', 
   LAST_DATE_MAJ = sysdate where (client,code) in (select (client,code) from fp_detail
  where valid = 1) ...

The full example is here: http://forums.devshed.com/oracle-development-96/how-to-update-from-two-tables-195893.html - from web archive since link was dead.

The beef is in having the columns that you want to use as the key in parentheses in the where clause before 'in' and have the select statement with the same column names in parentheses. where (column1,column2) in ( select (column1,column2) from table where "the set I want" );

heres a jquery plugin to do that

(function($) {
    $.fn.onEnter = function(func) {
        this.bind('keypress', function(e) {
            if (e.keyCode == 13) func.apply(this, [e]);    
        });               
        return this; 
     };
})(jQuery);

to use it, include the code and set it up like this:

$( function () {
    console.log($("input"));
    $("input").onEnter( function() {
        $(this).val("Enter key pressed");                
    });
});

Create a mutex that the running thread and the calling thread both have access to. When the running thread starts it locks the mutex, and when it ends it unlocks the mutex. To check if the thread is still running, the calling thread calls mutex.try_lock(). The return value of that is the status of the thread. (Just make sure to unlock the mutex if the try_lock worked)

One small problem with this, mutex.try_lock() will return false between the time the thread is created, and when it locks the mutex, but this can be avoided using a slightly more complex method.

Modern browsers now support the:

width: calc(100% - 100px);

To see the list of supported browser versions checkout: Can I use calc() as CSS unit value?

There is a jQuery fallback: css width: calc(100% -100px); alternative using jquery

List<T>.Add adds a single element. Instead, use List<T>.AddRange to add multiple values.

Additionally, List<T>.AddRange takes an IEnumerable<T>, so you don't need to convert tripDetails into a List<TripDetails>, you can pass it directly, e.g.:

tripDetailsCollection.AddRange(tripDetails);

That .toggle() method was removed from jQuery in version 1.9. You can do this instead:

$(document).ready(function() {
    $('#showmenu').click(function() {
            $('.menu').slideToggle("fast");
    });
});

Demo: http://jsfiddle.net/APA2S/1/

...but as with the code in your question that would slide up or down. To slide left or right you can do the following:

$(document).ready(function() {
    $('#showmenu').click(function() {
         $('.menu').toggle("slide");
    });
});

Demo: http://jsfiddle.net/APA2S/2/

Noting that this requires jQuery-UI's slide effect, but you added that tag to your question so I assume that is OK.

The thing is that you are using the option -t when running your container.

Could you check if enabling the tty option (see reference) in your docker-compose.yml file the container keeps running?

You can't. The emulator does not support Bluetooth, as mentioned in the SDK's docs and several other places. Android emulator does not have bluetooth capabilities".

You can only use real devices.

Emulator Limitations

The functional limitations of the emulator include:

• No support for placing or receiving actual phone calls. However, You can simulate phone calls (placed and received) through the emulator console
• No support for USB
• No support for device-attached headphones
• No support for determining SD card insert/eject
• No support for WiFi, Bluetooth, NFC

You're looking for Select which can be used to transform\project the input sequence:

Turns out it is possible to enter a host name directly into the playbook, so running the playbook with hosts: imac-2.local will work fine. But it's kind of clunky.

A better solution might be defining the playbook's hosts using a variable, then passing in a specific host address via --extra-vars:

# file: user.yml  (playbook)
---
- hosts: '{{ target }}'
  user: ...

Running the playbook:

ansible-playbook user.yml --extra-vars "target=imac-2.local"

If {{ target }} isn't defined, the playbook does nothing. A group from the hosts file can also be passed through if need be. Overall, this seems like a much safer way to construct a potentially destructive playbook.

Playbook targeting a single host:

$ ansible-playbook user.yml --extra-vars "target=imac-2.local" --list-hosts

playbook: user.yml

  play #1 (imac-2.local): host count=1
    imac-2.local

Playbook with a group of hosts:

$ ansible-playbook user.yml --extra-vars "target=office" --list-hosts

playbook: user.yml

  play #1 (office): host count=3
    imac-1.local
    imac-2.local
    imac-3.local

Forgetting to define hosts is safe!

$ ansible-playbook user.yml --list-hosts

playbook: user.yml

  play #1 ({{target}}): host count=0

As noted in the comments, there are some things to try: gc.collect (@EdChum) may clear stuff, for example. At least from my experience, these things sometimes work and often don't.

There is one thing that always works, however, because it is done at the OS, not language, level.

Suppose you have a function that creates an intermediate huge DataFrame, and returns a smaller result (which might also be a DataFrame):

def huge_intermediate_calc(something):
    ...
    huge_df = pd.DataFrame(...)
    ...
    return some_aggregate

Then if you do something like

import multiprocessing

result = multiprocessing.Pool(1).map(huge_intermediate_calc, [something_])[0]

Then the function is executed at a different process. When that process completes, the OS retakes all the resources it used. There's really nothing Python, pandas, the garbage collector, could do to stop that.

wt = tt - cpu tm.
Tt = cpu tm + wt.

Where wt is a waiting time and tt is turnaround time. Cpu time is also called burst time.

Stop abusing private fields!!!

The comments here seem to be overwhelmingly supportive towards using private fields. Well, then I have something different to say.

Are private fields good in principle? Yes. But saying that a golden rule is make everything private when you're not sure is definitely wrong! You won't see the problem until you run into one. In my opinion, you should mark fields as protected if you're not sure.

There are two cases you want to extend a class:

• You want to add extra functionality to a base class
• You want to modify existing class that's outside the current package (in some libraries perhaps)

There's nothing wrong with private fields in the first case. The fact that people are abusing private fields makes it so frustrating when you find out you can't modify shit.

Consider a simple library that models cars:

class Car {
    private screw;
    public assembleCar() {
       screw.install();
    };
    private putScrewsTogether() {
       ...
    };
}

The library author thought: there's no reason the users of my library need to access the implementation detail of assembleCar() right? Let's mark screw as private.

Well, the author is wrong. If you want to modify only the assembleCar() method without copying the whole class into your package, you're out of luck. You have to rewrite your own screw field. Let's say this car uses a dozen of screws, and each of them involves some untrivial initialization code in different private methods, and these screws are all marked private. At this point, it starts to suck.

Yes, you can argue with me that well the library author could have written better code so there's nothing wrong with private fields. I'm not arguing that private field is a problem with OOP. It is a problem when people are using them.

The moral of the story is, if you're writing a library, you never know if your users want to access a particular field. If you're unsure, mark it protected so everyone would be happier later. At least don't abuse private field.

I very much support Nick's answer.

In PLSQL block, columns of select statements must be assigned to variables, which is not the case in SQL statements.

The second BEGIN's SQL statement doesn't have INTO clause and that caused the error.

FileOutputStream fos = new FileOutputStream("File_Name", true);
fos.write(data);

the true allows to append the data in the existing file. If we will write

FileOutputStream fos = new FileOutputStream("File_Name");

It will overwrite the existing file. So go for first approach.

Java nio has options to access creationTime and other meta-data as long as the filesystem provides it. Check this link out

For example(Provided based on @ydaetskcoR's comment):

Path file = ...;
BasicFileAttributes attr = Files.readAttributes(file, BasicFileAttributes.class);

System.out.println("creationTime: " + attr.creationTime());
System.out.println("lastAccessTime: " + attr.lastAccessTime());
System.out.println("lastModifiedTime: " + attr.lastModifiedTime());

Convert.ToInt32

has 19 overloads or 19 different ways that you can call it. Maybe more in 2010 versions.

It will attempt to convert from the following TYPES;

Object, Boolean, Char, SByte, Byte, Int16, UInt16, Int32, UInt32, Int64, UInt64, Single, Double, Decimal, String, Date

and it also has a number of other methods; one to do with a number base and 2 methods involve a System.IFormatProvider

Parse on the other hand only has 4 overloads or 4 different ways you can call the method.

Integer.Parse( s As String)

Integer.Parse( s As String,  style As System.Globalization.NumberStyles )

Integer.Parse( s As String, provider As System.IFormatProvider )

Integer.Parse( s As String,  style As System.Globalization.NumberStyles, provider As System.IFormatProvider )

1.Install-Package Microsoft.AspNet.WebApi.Cors

2 . Add this code in WebApiConfig.cs.

public static void Register(HttpConfiguration config)
{
    // Web API configuration and services

    // Web API routes

    config.EnableCors();

    config.MapHttpAttributeRoutes();

    config.Routes.MapHttpRoute(
        name: "DefaultApi",
        routeTemplate: "api/{controller}/{id}",
        defaults: new { id = RouteParameter.Optional }
    );
}

3. Add this

using System.Web.Http.Cors; 

4. Add this code in Api Controller (HomeController.cs)

[EnableCors(origins: "*", headers: "*", methods: "*")]
public class HomeController : ApiController
{
    [HttpGet]
    [Route("api/Home/test")]
    public string test()
    {
       return "";
    }
}

I have run into the same problem as w00, but I didn't had the freedom to rewrite the base functionality of the component in which this problem (E_NOTICE) occured. I've been able to fix the issue using an ArrayObject in stead of the basic type array(). This will return an object, which will defaulty be returned by reference.

For versions earlier than JPA 2.1, JPA provides only two ways to deal with enums, by their name or by their ordinal. And the standard JPA doesn't support custom types. So:

• If you want to do custom type conversions, you'll have to use a provider extension (with Hibernate UserType, EclipseLink Converter, etc). (the second solution). ~or~
• You'll have to use the @PrePersist and @PostLoad trick (the first solution). ~or~
• Annotate getter and setter taking and returning the int value ~or~
• Use an integer attribute at the entity level and perform a translation in getters and setters.

I'll illustrate the latest option (this is a basic implementation, tweak it as required):

@Entity
@Table(name = "AUTHORITY_")
public class Authority implements Serializable {

    public enum Right {
        READ(100), WRITE(200), EDITOR (300);

        private int value;

        Right(int value) { this.value = value; }    

        public int getValue() { return value; }

        public static Right parse(int id) {
            Right right = null; // Default
            for (Right item : Right.values()) {
                if (item.getValue()==id) {
                    right = item;
                    break;
                }
            }
            return right;
        }

    };

    @Id
    @GeneratedValue(strategy = GenerationType.AUTO)
    @Column(name = "AUTHORITY_ID")
    private Long id;

    @Column(name = "RIGHT_ID")
    private int rightId;

    public Right getRight () {
        return Right.parse(this.rightId);
    }

    public void setRight(Right right) {
        this.rightId = right.getValue();
    }

}

If you are looking inside dockerfile while creating image, add this line:

RUN apk add --update yourPackageName

I would suggest Jetbrain's IDE: DataGrip https://www.jetbrains.com/datagrip/

<td class="first"> <?php echo $proxy ?> </td> is inside a literal string that you are echoing. End the string, or concatenate it correctly:

<td class="first">' . $proxy . '</td>

Try

$(".text").text(data);

Or to convert the data received to a string.

On Arch Linux run the following:

sudo pacman -S base-devel

I have a similar experience and I believe that it might be the browser that is cutting the session short. I also set the maxIdleTimeout, but the session is dropped regardless. To me, it looks like it is the client (the browser) that is timing out the session and then hangs up.

Don't know how to work around it.

Please use dataset

var article = document.querySelector('#electriccars'),
    data = article.dataset;

// data.columns -> "3"
// data.indexnumber -> "12314"
// data.parent -> "cars"

so in your case for setting data:

getElementById('item1').dataset.icon = "base2.gif";

A build, as Makefile understands it, consists of a lot of targets. For example, to build a project you might need

1. Build file1.o out of file1.c
2. Build file2.o out of file2.c
3. Build file3.o out of file3.c
4. Build executable1 out of file1.o and file3.o
5. Build executable2 out of file2.o

If you implemented this workflow with makefile, you could make each of the targets separately. For example, if you wrote

make file1.o

it would only build that file, if necessary.

The name of all is not fixed. It's just a conventional name; all target denotes that if you invoke it, make will build all what's needed to make a complete build. This is usually a dummy target, which doesn't create any files, but merely depends on the other files. For the example above, building all necessary is building executables, the other files being pulled in as dependencies. So in the makefile it looks like this:

all: executable1 executable2

all target is usually the first in the makefile, since if you just write make in command line, without specifying the target, it will build the first target. And you expect it to be all.

all is usually also a .PHONY target. Learn more here.

just use this:

<script>
  var ctx = document.getElementById("myChart").getContext('2d');
  var myChart = new Chart(ctx, {
    type: 'bar',
    data: {
      labels: ["1","2","3","4","5","6","7","8","9","10","11",],
      datasets: [{
        label: 'YOUR LABEL',
        backgroundColor: [
          "#566573",
          "#99a3a4",

For someone who has the problem with populate and also wants to do this:

• chat with simple text & quick replies (bubbles)
• 4 database collections for chat: clients, users, rooms, messasges.
• same message DB structure for 3 types of senders: bot, users & clients
• refPath or dynamic reference
• populate with path and model options
• use findOneAndReplace/replaceOne with $exists
• create a new document if the fetched document doesn't exist

CONTEXT

Goal

1. Save a new simple text message to the database & populate it with the user or client data (2 different models).
2. Save a new quickReplies message to the database and populate it with the user or client data.
3. Save each message its sender type: clients, users & bot.
4. Populate only the messages who have the sender clients or users with its Mongoose Models. _sender type client models is clients, for user is users.

Message schema:

const messageSchema = new Schema({
    room: {
        type: Schema.Types.ObjectId,
        ref: 'rooms',
        required: [true, `Room's id`]
    },
    sender: {
         _id: { type: Schema.Types.Mixed },
        type: {
            type: String,
            enum: ['clients', 'users', 'bot'],
            required: [true, 'Only 3 options: clients, users or bot.']
        }
    },
    timetoken: {
        type: String,
        required: [true, 'It has to be a Nanosecond-precision UTC string']
    },
    data: {
        lang: String,
        // Format samples on https://docs.chatfuel.com/api/json-api/json-api
        type: {
            text: String,
            quickReplies: [
                {
                    text: String,
                    // Blocks' ids.
                    goToBlocks: [String]
                }
            ]
        }
    }

mongoose.model('messages', messageSchema);

SOLUTION

My server side API request

My code

Utility function (on chatUtils.js file) to get the type of message that you want to save:

/**
 * We filter what type of message is.
 *
 * @param {Object} message
 * @returns {string} The type of message.
 */
const getMessageType = message => {
    const { type } = message.data;
    const text = 'text',
        quickReplies = 'quickReplies';

    if (type.hasOwnProperty(text)) return text;
    else if (type.hasOwnProperty(quickReplies)) return quickReplies;
};

/**
 * Get the Mongoose's Model of the message's sender. We use
 * the sender type to find the Model.
 *
 * @param {Object} message - The message contains the sender type.
 */
const getSenderModel = message => {
    switch (message.sender.type) {
        case 'clients':
            return 'clients';
        case 'users':
            return 'users';
        default:
            return null;
    }
};

module.exports = {
    getMessageType,
    getSenderModel
};

My server side (using Nodejs) to get the request of saving the message:

app.post('/api/rooms/:roomId/messages/new', async (req, res) => {
        const { roomId } = req.params;
        const { sender, timetoken, data } = req.body;
        const { uuid, state } = sender;
        const { type } = state;
        const { lang } = data;

        // For more info about message structure, look up Message Schema.
        let message = {

            // Bad Request
            res.status(400).send(false);
        }
    });

TIPs:

For the database:

• Every message is a document itself.
• Instead of using refPath, we use the util getSenderModel that is used on populate(). This is because of the bot. The sender.type can be: users with his database, clients with his database and bot without a database. The refPath needs true Model reference, if not, Mongooose throw an error.
• sender._id can be type ObjectId for users and clients, or null for the bot.

For API request logic:

• We replace the quickReply message (Message DB has to have only one quickReply, but as many simple text messages as you want). We use the findOneAndUpdate instead of replaceOne or findOneAndReplace.
• We execute the query operation (the findOneAndUpdate) and the populate operation with the callback of each one. This is important if you don't know if use async/await, then(), exec() or callback(err, document). For more info look the Populate Doc.
• We replace the quick reply message with the overwrite option and without $set query operator.
• If we don't find the quick reply, we create a new one. You have to tell to Mongoose this with upsert option.
• We populate only one time, for the replaced message or the new saved message.
• We return to callbacks, whatever is the message we've saved with findOneAndUpdate and for the populate().
• In populate, we create a custom dynamic Model reference with the getSenderModel. We can use the Mongoose dynamic reference because the sender.type for bot hasn't any Mongoose Model. We use a Populating Across Database with model and path optins.

I've spend a lot of hours solving little problems here and there and I hope this will help someone!

What you also should consider, is keeping a reference to the created element, then you can easily remove it specificly:

   var newUL = $('<ul><li>test</li></ul>');
   $(this).append(newUL);

   // Later ...

   newUL.remove();

If u need to connect your application to a server you can do it through PHP/MySQL and JSON http://www.androidhive.info/2012/05/how-to-connect-android-with-php-mysql/ .Mysql Connection code should be in AsynTask class. Dont run it in Main Thread.

Listing the entries in the current directory (for directories in os.listdir(os.getcwd()):) and then interpreting those entries as subdirectories of an entirely different directory (dir = os.path.join('/home/user/workspace', directories)) is one thing that looks fishy.

You should use back tick character (`) eg:

create table if not exists misc_info (
id INTEGER PRIMARY KEY AUTO_INCREMENT NOT NULL,
`key` TEXT UNIQUE NOT NULL,
value TEXT NOT NULL)ENGINE=INNODB;

I faced similar scenario. It was happening because classA's initilization was dependent on classB's initialization. When classB's static block faced runtime exception, classB was not initialized. Because of this, classB did not throw any exception and classA's initialization failed too.

class A{//this class will never be initialized because class B won't intialize
  static{
    try{
      classB.someStaticMethod();
    }catch(Exception e){
      sysout("This comment will never be printed");
    }
 }
}

class B{//this class will never be initialized
 static{
    int i = 1/0;//throw run time exception 
 }

 public static void someStaticMethod(){}
}

And yes...catching Exception will catch run time exceptions as well.

Let me copy/paste the documentation section which it I wrote about week or two ago, after having a problem similar to yours:

import requests
import logging

# these two lines enable debugging at httplib level (requests->urllib3->httplib)
# you will see the REQUEST, including HEADERS and DATA, and RESPONSE with HEADERS but without DATA.
# the only thing missing will be the response.body which is not logged.
import httplib
httplib.HTTPConnection.debuglevel = 1

logging.basicConfig() # you need to initialize logging, otherwise you will not see anything from requests
logging.getLogger().setLevel(logging.DEBUG)
requests_log = logging.getLogger("requests.packages.urllib3")
requests_log.setLevel(logging.DEBUG)
requests_log.propagate = True

requests.get('http://httpbin.org/headers')

You can use the phpmyadmin setup page (./phpmyadmin/setup) to generate a new config file (config.inc.php) for you. This file is found at the root of the phpMyAdmin directory.

Just create the config folder as prompted in setup page, add your servers, then click the 'Save' button. This will create a new config file in the config folder you just created.

You now have only to move the config.inc.php file to the main phpMyAdmin folder, or just copy the lines concerning the servers if you got some old configuration done already you'd like to keep.

Don't forget to delete the config folder afterwards.

I know no-one is asking for a jQuery solution here, but might be worth mentioning that with jQuery you can just ask for:$('#selectorid').val()

Step 1: View page code

<input type="button" id="btnExport" value="Export" class="btn btn-primary" />
<script>
  $(document).ready(function () {

 $('#btnExport').click(function () {          

  window.location = '/Inventory/ExportInventory';

        });
});
</script>

Step 2: Controller Code

  public ActionResult ExportInventory()
        {
            //Load Data
            var dataInventory = _inventoryService.InventoryListByPharmacyId(pId);
            string xml=String.Empty;
            XmlDocument xmlDoc = new XmlDocument();

            XmlSerializer xmlSerializer = new XmlSerializer(dataInventory.GetType());

            using (MemoryStream xmlStream = new MemoryStream())
            {
                xmlSerializer.Serialize(xmlStream, dataInventory);
                xmlStream.Position = 0;
                xmlDoc.Load(xmlStream);
                xml = xmlDoc.InnerXml;
            }

            var fName = string.Format("Inventory-{0}", DateTime.Now.ToString("s"));

            byte[] fileContents = Encoding.UTF8.GetBytes(xml);

            return File(fileContents, "application/vnd.ms-excel", fName);
        }

Canvas does not using .png file as background image. changing to other file extensions like gif or jpg works fine.

Even Rest Template can be an option :

String payload = "<?xml version=\"1.0\" encoding=\"UTF-8\"?<RequestDAO>....";
    RestTemplate rest = new RestTemplate();

    HttpHeaders headers = new HttpHeaders();
    headers.add("Content-Type", "application/xml");
    headers.add("Accept", "*/*");
    HttpEntity<String> requestEntity = new HttpEntity<String>(payload, headers);
    ResponseEntity<String> responseEntity =
            rest.exchange(url, HttpMethod.PUT, requestEntity, String.class);

     responseEntity.getBody().toString();

I assume you are using integers to represent your year, month, and day? If you want to remain consistent, use the Date methods.

Calendar cal = new Calendar();
int currentYear, currentMonth, currentDay; 
currentYear = cal.get(Calendar.YEAR); 
currentMonth = cal.get(Calendar.MONTH); 
currentDay = cal.get(Calendar.DAY_OF_WEEK);

     if(startYear < currentYear)
                {
                    message = message + "Start Date is Before Today" + "\n";
                }
            else if(startMonth < currentMonth && startYear <= currentYear)
                    {
                        message = message + "Start Date is Before Today" + "\n";
                    }
            else if(startDay < currentDay && startMonth <= currentMonth && startYear <= currentYear)
                        {
                            message = message + "Start Date is Before Today" + "\n";
                        }

It is possible only in the case when the factor labels match the original values. I will explain it with an example.

Assume the data is vector x:

x <- c(20, 10, 30, 20, 10, 40, 10, 40)

Now I will create a factor with four labels:

f <- factor(x, levels = c(10, 20, 30, 40), labels = c("A", "B", "C", "D"))

1) x is with type double, f is with type integer. This is the first unavoidable loss of information. Factors are always stored as integers.

> typeof(x)
[1] "double"
> typeof(f)
[1] "integer"

2) It is not possible to revert back to the original values (10, 20, 30, 40) having only f available. We can see that f holds only integer values 1, 2, 3, 4 and two attributes - the list of labels ("A", "B", "C", "D") and the class attribute "factor". Nothing more.

> str(f)
 Factor w/ 4 levels "A","B","C","D": 2 1 3 2 1 4 1 4
> attributes(f)
$levels
[1] "A" "B" "C" "D"

$class
[1] "factor"

To revert back to the original values we have to know the values of levels used in creating the factor. In this case c(10, 20, 30, 40). If we know the original levels (in correct order), we can revert back to the original values.

> orig_levels <- c(10, 20, 30, 40)
> x1 <- orig_levels[f]
> all.equal(x, x1)
[1] TRUE

And this will work only in case when labels have been defined for all possible values in the original data.

So if you will need the original values, you have to keep them. Otherwise there is a high chance it will not be possible to get back to them only from a factor.

I tried using the .mp4 format to play a video on Android devices but that did not go well. So after some trial and error, I converted the video into the .webm format and following code with no extra javascript or JQuery:

<video id="video" class="video" muted loop autoplay>
    <source src="../media/some_video.webm" type="video/webm">
    Sorry, your browser doesn't support embedded videos.
</video>

It worked on an older Android device (at least a few years old as of 2020).

another way to implement singleton in c#, i personally prefer this way because you can access the instance of the singeton class as a property instead of a method.

public class Singleton
    {
        private static Singleton instance;

        private Singleton() { }

        public static Singleton Instance
        {
            get
            {
                if (instance == null)
                    instance = new Singleton();
                return instance;
            }
        }

        //instance methods
    }

but well, as far as i know both ways are considered 'right' so it's just a thing of personal flavor.

You need to create new Book objects then put those in a new List:

List<Book> books_2 = books_1.Select(book => new Book(book.title)).ToList();

Update: Slightly simpler... List<T> has a method called ConvertAll that returns a new list:

List<Book> books_2 = books_1.ConvertAll(book => new Book(book.title));

Try std::find

vector<int>::iterator it = std::find(v.begin(), v.end(), 123);

if(it==v.end()){

    std::cout<<"Element not found";
}

Embedded C is generally an extension of the C language, they are more or less similar. However, some differences do exist, such as:

• C is generally used for desktop computers, while embedded C is for microcontroller based applications.

• C can use the resources of a desktop PC like memory, OS, etc. While, embedded C has to use with the limited resources, such as RAM, ROM, I/Os on an embedded processor.

• Embedded C includes extra features over C, such as fixed point types, multiple memory areas, and I/O register mapping.

• Compilers for C (ANSI C) typically generate OS dependant executables. Embedded C requires compilers to create files to be downloaded to the microcontrollers/microprocessors where it needs to run.

Refer difference between C and embedded C

Array.prototype.unique = function() {
    var a = [],k = 0,e;
    for(k=0;e=this[k];k++)
      if(a.indexOf(e)==-1)
           a.push(e);
    return a;
}
[1,2,3,4,33,23,2,3,22,1].unique(); // return [1,2,3,4,33,23,22]

See http://www.w3schools.com/tags/att_input_accept.asp:

The accept attribute is supported in all major browsers, except Internet Explorer and Safari. Definition and Usage

The accept attribute specifies the types of files that the server accepts (that can be submitted through a file upload).

Note: The accept attribute can only be used with <input type="file">.

Tip: Do not use this attribute as a validation tool. File uploads should be validated on the server.

Syntax <input accept="audio/*|video/*|image/*|MIME_type" />

Tip: To specify more than one value, separate the values with a comma (e.g. <input accept="audio/*,video/*,image/*" />.

SELECT Call.ID, Call.date, Call.phone_number 
FROM Call 
LEFT OUTER JOIN Phone_Book 
  ON (Call.phone_number=Phone_book.phone_number) 
  WHERE Phone_book.phone_number IS NULL

Should remove the subquery, allowing the query optimiser to work its magic.

Also, avoid "SELECT *" because it can break your code if someone alters the underlying tables or views (and it's inefficient).

Operator + is a unary operator which converts value to number. Below I prepared a table with corresponding results of using this operator for different values.

+-----------------------------+-----------+
| Value                       | + (Value) |
+-----------------------------+-----------+
| 1                           | 1         |
| '-1'                        | -1        |
| '3.14'                      | 3.14      |
| '3'                         | 3         |
| '0xAA'                      | 170       |
| true                        | 1         |
| false                       | 0         |
| null                        | 0         |
| 'Infinity'                  | Infinity  |
| 'infinity'                  | NaN       |
| '10a'                       | NaN       |
| undefined                   | Nan       |
| ['Apple']                   | Nan       |
| function(val){ return val } | NaN       |
+-----------------------------+-----------+

Operator + returns value for objects which have implemented method valueOf.

let something = {
    valueOf: function () {
        return 25;
    }
};

console.log(+something);

The RESTful pretty URL design is about displaying a resource based on a structure (directory-like structure, date: articles/2005/5/13, object and it's attributes,..), the slash / indicates hierarchical structure, use the -id instead.

Hierarchical structure

I would personaly prefer:

/garage-id/cars/car-id
/cars/car-id   #for cars not in garages

If a user removes the /car-id part, it brings the cars preview - intuitive. User exactly knows where in the tree he is, what is he looking at. He knows from the first look, that garages and cars are in relation. /car-id also denotes that it belongs together unlike /car/id.

Searching

The searchquery is OK as it is, there is only your preference, what should be taken into account. The funny part comes when joining searches (see below).

/cars?color=blue;type=sedan   #most prefered by me
/cars;color-blue+doors-4+type-sedan   #looks good when using car-id
/cars?color=blue&doors=4&type=sedan   #I don't recommend using &*

Or basically anything what isn't a slash as explained above.
The formula: /cars[?;]color[=-:]blue[,;+&], * though I wouldn't use the & sign as it is unrecognizable from the text at first glance.

** Did you know that passing JSON object in URI is RESTful? **

Lists of options

/cars?color=black,blue,red;doors=3,5;type=sedan   #most prefered by me
/cars?color:black:blue:red;doors:3:5;type:sedan
/cars?color(black,blue,red);doors(3,5);type(sedan)   #does not look bad at all
/cars?color:(black,blue,red);doors:(3,5);type:sedan   #little difference

possible features?

Negate search strings (!)
To search any cars, but not black and red:
?color=!black,!red
color:(!black,!red)

Joined searches
Search red or blue or black cars with 3 doors in garages id 1..20 or 101..103 or 999 but not 5 /garage[id=1-20,101-103,999,!5]/cars[color=red,blue,black;doors=3]
You can then construct more complex search queries. (Look at CSS3 attribute matching for the idea of matching substrings. E.g. searching users containing "bar" user*=bar.)

Conclusion

Anyway, this might be the most important part for you, because you can do it however you like after all, just keep in mind that RESTful URI represents a structure which is easily understood e.g. directory-like /directory/file, /collection/node/item, dates /articles/{year}/{month}/{day}.. And when you omit any of last segments, you immediately know what you get.

So.., all these characters are allowed unencoded:

• unreserved: a-zA-Z0-9_.-~
  Typically allowed both encoded and not, both uses are then equivalent.
• special characters: $-_.+!*'(),
• reserved: ;/?:@=&
  May be used unencoded for the purpose they represent, otherwise they must be encoded.

• unsafe: <>"#%{}|\^~[]`
  Why unsafe and why should rather be encoded: RFC 1738 see 2.2

  Also see RFC 1738#page-20 for more character classes.

RFC 3986 see 2.2
Despite of what I previously said, here is a common distinction of delimeters, meaning that some "are" more important than others.

• generic delimeters: :/?#[]@
• sub-delimeters: !$&'()*+,;=
