Storyboard Approach

Select CollectionView in your storyboard and go to size inspector and set min spacing for cells and lines as 5

Swift 5 Programmatically

lazy var collectionView: UICollectionView = {
        let layout = UICollectionViewFlowLayout()
        layout.scrollDirection = .horizontal

        //Provide Width and Height According to your need
        let width = UIScreen.main.bounds.width / 4
        let height = UIScreen.main.bounds.height / 10
        layout.itemSize = CGSize(width: width, height: height)

        //For Adjusting the cells spacing
        layout.minimumInteritemSpacing = 5
        layout.minimumLineSpacing = 5

        return UICollectionView(frame: self.view.frame, collectionViewLayout: layout)
    }()

Kotlin

data class Player(val name : String, val surname: String)

val json = [
  {
    "name": "name 1",
    "surname": "surname 1"
  },
  {
    "name": "name 2",
    "surname": "surname 2"
  },
  {
    "name": "name 3",
    "surname": "surname 3"
  }
]

val typeToken = object : TypeToken<List<Player>>() {}.type
val playerArray = Gson().fromJson<List<Player>>(json, typeToken)

OR

val playerArray = Gson().fromJson(json, Array<Player>::class.java)

I had a similar error and fixed as follows:

(My 'fix' is based on an assumption which may or may not be correct as I don't know that much about how subversion works internally, but it definitely worked for me)

I am assuming that .svn\text-base\import.php.svn-base is expected to match the latest commit.

When I checked the file I was having the error on , the base file did NOT match the latest commit in the repository.

I copied the text from the latest commit and saved that in the .svn folder, replacing the incorrect file (made a backup copy in case my assumptions were wrong). (file was marked read only, I cleared that flag, overwrote and set it back to read only)

I was then able to commit successfully.

I find it much easier to "extend" via assigning in a bigger matrix. E.g.

import numpy as np
p = np.array([[1,2], [3,4]])
g = np.array(range(20))
g.shape = (4,5)
g[0:2, 0:2] = p

Here are the arrays:

p

   array([[1, 2],
       [3, 4]])

g:

array([[ 0,  1,  2,  3,  4],
       [ 5,  6,  7,  8,  9],
       [10, 11, 12, 13, 14],
       [15, 16, 17, 18, 19]])

and the resulting g after assignment:

   array([[ 1,  2,  2,  3,  4],
       [ 3,  4,  7,  8,  9],
       [10, 11, 12, 13, 14],
       [15, 16, 17, 18, 19]])

Here is a (non-idiomatic) Scala version of the smoothed z-score algorithm:

/**
  * Smoothed zero-score alogrithm shamelessly copied from https://stackoverflow.com/a/22640362/6029703
  * Uses a rolling mean and a rolling deviation (separate) to identify peaks in a vector
  *
  * @param y - The input vector to analyze
  * @param lag - The lag of the moving window (i.e. how big the window is)
  * @param threshold - The z-score at which the algorithm signals (i.e. how many standard deviations away from the moving mean a peak (or signal) is)
  * @param influence - The influence (between 0 and 1) of new signals on the mean and standard deviation (how much a peak (or signal) should affect other values near it)
  * @return - The calculated averages (avgFilter) and deviations (stdFilter), and the signals (signals)
  */
private def smoothedZScore(y: Seq[Double], lag: Int, threshold: Double, influence: Double): Seq[Int] = {
  val stats = new SummaryStatistics()

  // the results (peaks, 1 or -1) of our algorithm
  val signals = mutable.ArrayBuffer.fill(y.length)(0)

  // filter out the signals (peaks) from our original list (using influence arg)
  val filteredY = y.to[mutable.ArrayBuffer]

  // the current average of the rolling window

  avgFilter(lag - 1) = stats.getMean
  stdFilter(lag - 1) = Math.sqrt(stats.getPopulationVariance) // getStandardDeviation() uses sample variance (not what we want)

  // loop input starting at end of rolling window
  y.zipWithIndex.slice(lag, y.length - 1).foreach {
    case (s: Double, i: Int) =>

      if (Math.abs(s - avgFilter(i - 1)) > threshold * stdFilter(i - 1)) {

        signals(i) = if (s > avgFilter(i - 1)) 1 else -1

mongod defaults the database location to /data/db/.

If you run ps -xa | grep mongod and you don't see a --dbpath which explicitly tells mongod to look at that parameter for the db location and you don't have a dbpath in your mongodb.conf, then the default location will be: /data/db/ and you should look there.

This should work :

str = str.replace(/[^a-z0-9-]/g, '');

Everything between the indicates what your are looking for

1. / is here to delimit your pattern so you have one to start and one to end
2. [] indicates the pattern your are looking for on one specific character
3. ^ indicates that you want every character NOT corresponding to what follows
4. a-z matches any character between 'a' and 'z' included
5. 0-9 matches any digit between '0' and '9' included (meaning any digit)
6. - the '-' character
7. g at the end is a special parameter saying that you do not want you regex to stop on the first character matching your pattern but to continue on the whole string

Then your expression is delimited by / before and after. So here you say "every character not being a letter, a digit or a '-' will be removed from the string".

99.999% of my time is looking at history by git lg and the 0.001% is by git log.

I just want to share two log aliases that might be useful (configure from .gitconfig):

[Alias]
     lg = log --graph --pretty=format:'%Cred%h%Creset %ad %s %C(yellow)%d%Creset %C(bold blue)<%an>%Creset' --date=short
     hist = log --graph --full-history --all --pretty=format:'%Cred%h%Creset %ad %s %C(yellow)%d%Creset %C(bold blue)<%an>%Creset' --date=short

• git lg will see the current branch history.
• git hist will see the whole branch history.

Other answers advice to use a file in the top-level of the project. This is not necessary if you use pathlib.Path and parent (Python 3.4 and up). Consider the following directory structure where all files except README.md and utils.py have been omitted.

project
¦   README.md
|
+---src
¦   ¦   utils.py
|   |   ...
|   ...

In utils.py we define the following function.

from pathlib import Path

def get_project_root() -> Path:
    return Path(__file__).parent.parent

In any module in the project we can now get the project root as follows.

from src.utils import get_project_root

root = get_project_root()

Benefits: Any module which calls get_project_root can be moved without changing program behavior. Only when the module utils.py is moved we have to update get_project_root and the imports (refactoring tools can be used to automate this).

Obviously someone either needs to write an intelligible book on git, or git needs to be better explained in the documentation. Faced with this same problem I guessed that

cd <working copy>
git revert master

would undo the last commit which is seemed to do.

There is a solution after reloading the page and keeping the expected tab as selected.

Suppose after saving data the redirected url is : my_url#tab_2

Now through the following script your expected tab will remain selected.

$(document).ready(function(){
    var url = document.location.toString();
    if (url.match('#')) {
        $('.nav-tabs a[href="#' + url.split('#')[1] + '"]').tab('show');
        $('.nav-tabs a').removeClass('active');
    }
});

It is likely that you do not have the IUSR_computername permission on that folder. I've just had a quick scan and it looks like you will find the information you need here.

If that isn't the case, are you prompted for your username and password by the browser? If so it may be that IIS is configured to use Integrated authentication only, as described here.

It's hard for us to bind a specific USB device to a docker container which is also specific. As you can see, the recommended way to achieve is:

docker run -t -i --privileged -v /dev/bus/usb:/dev/bus/usb ubuntu bash

It will bind all the devices to this container. It's unsafe. Every containers were granted to operate all of them.

Another way is binding devices by devpath. It may looks like:

docker run -t -i --privileged -v /dev/bus/usb/001/002:/dev/bus/usb/001/002 ubuntu bash

or --device (better, no privileged):

docker run -t -i --device /dev/bus/usb/001/002 ubuntu bash

Much safer. But actually it is hard to know what the devpath of a specific device is.

I have wrote this repo to solve this problem.

https://github.com/williamfzc/usb2container

After deploying this server, you can easily get all the connected devices' information via HTTP request:

curl 127.0.0.1:9410/api/device

and get:

{
    "/devices/pci0000:00/0000:00:14.0/usb1/1-13": {
        "ACTION": "add",
        "DEVPATH": "/devices/pci0000:00/0000:00:14.0/usb1/1-13",
        "DEVTYPE": "usb_device",
        "DRIVER": "usb",
        "ID_BUS": "usb",
        "ID_FOR_SEAT": "xxxxx",
        "ID_MODEL": "xxxxx",
        "ID_MODEL_ID": "xxxxx",
        "ID_PATH": "xxxxx",
        "ID_PATH_TAG": "xxxxx",
        "ID_REVISION": "xxxxx",
        "ID_SERIAL": "xxxxx",
        "ID_SERIAL_SHORT": "xxxxx",
        "ID_USB_INTERFACES": "xxxxx",
        "ID_VENDOR": "xxxxx",
        "ID_VENDOR_ENC": "xxxxx",
        "ID_VENDOR_FROM_DATABASE": "",
        "ID_VENDOR_ID": "xxxxx",
        "INTERFACE": "",
        "MAJOR": "189",
        "MINOR": "119",
        "MODALIAS": "",
        "PRODUCT": "xxxxx",
        "SEQNUM": "xxxxx",
        "SUBSYSTEM": "usb",
        "TAGS": "",
        "TYPE": "0/0/0",
        "USEC_INITIALIZED": "xxxxx",
        "adb_user": "",
        "_empty": false,
        "DEVNAME": "/dev/bus/usb/001/120",
        "BUSNUM": "001",
        "DEVNUM": "120",
        "ID_MODEL_ENC": "xxxxx"
    },
    ...
}

and bind them to your containers. For example, you can see the DEVNAME of this device is /dev/bus/usb/001/120:

docker run -t -i --device /dev/bus/usb/001/120 ubuntu bash

Maybe it will help.

You can add escaped double quotes like this: String name = "\"john\"";

you have id="#message"... should be id="message"

What i have done is that import a new project into eclipse workspace, and that path of that was be

and add as library in your project.. that it .. simple!! you might require to add support library in your project.

"Sleep" state connections are most often created by code that maintains persistent connections to the database.

This could include either connection pools created by application frameworks, or client-side database administration tools.

As mentioned above in the comments, there is really no reason to worry about these connections... unless of course you have no idea where the connection is coming from.

(CAVEAT: If you had a long list of these kinds of connections, there might be a danger of running out of simultaneous connections.)

For your second question, it seems the leading-quote syntax (\'A) is specific to printf:

If the leading character is a single-quote or double-quote, the value shall be the numeric value in the underlying codeset of the character following the single-quote or double-quote.

From https://pubs.opengroup.org/onlinepubs/9699919799/utilities/printf.html

Use this:

void double_to_char(double f,char * buffer){
    gcvt(f,10,buffer);
}

this works for me

object Json_Object=maintainerService.Convert_To_JSON(Jobitem);
ScriptManager.RegisterClientScriptBlock(this,GetType(), "Javascript", "SelectedJobsMaintainer("+Json_Object+"); ",true);

I was able to connect Robomongo to a remote instance of MongoDB running on Mongo Labs using the connection string as follows:

1. Download the latest version of Robomongo. I downloaded 0.9 RC6 from here.

2. From the connection string, populate the server address and port numbers as follows.

   

3. Populate DB name and username and password as follows under the authentication tab.

   

4. Test the connection.

   

   

document.form.p_id.length ... not count().

You really should give your form an id

<form id="myform">

Then refer to it using:

var theForm = document.getElementById("myform");

Then refer to the elements like:

for(var i = 0; i < theForm.p_id.length; i++){

There is a slightly better way to access attached files. You could use template reference variable to get an instance of the input element.

Here is an example based on the first answer:

@Component({
  selector: 'my-app',
  template: `
    <div>
      <input type="file" #file (change)="onChange(file.files)"/>
    </div>
  `,
  providers: [ UploadService ]
})

export class AppComponent {
  onChange(files) {
    console.log(files);
  }
}

Here is an example app to demonstrate this in action.

Template reference variables might be useful, e.g. you could access them via @ViewChild directly in the controller.

You have it reversed. The 100 should be the first parameter (it's the key) and the "one" should be the second parameter (it's the value).

Read the javadoc for HashMap and that might help you: HashMap

To get the value, use hashmap.get(100).

You can try this-

mysql> select @@datadir;

PS- It works on every platform.

There are times when it's useful to implement an interface that will be returned from within the class, but the implementation of that interface should be completely hidden from the outside world.

As an example - prior to the addition of yield to C#, one way to implement enumerators was to put the implementation of the enumerator as a private class within a collection. This would provide easy access to the members of the collection, but the outside world would not need/see the details of how this is implemented.

try this query below:

Insert into tab1 (tab1.column1,tab1.column2) 
select tab2.column1, 'hard coded  value' 
from tab2 
where tab2.column='value';

Here is one solution:

div.row { 
  border: 1px solid;
  border-bottom: 0px;
}
.container div.row:last-child {
  border-bottom: 1px solid;
}

I'm not 100% its the most effiecent, but it works :D

It might be useful to debug the client, turn off Tools\Options\Debugging\General\'Enable Just My Code', click Debug\Exceptions\'catch all first-chance exceptions' for managed CLR exceptions, and see if there is an exception under-the-hood on the client before the protocol exception and before the message hits the wire. (My guess would be some kind of serialization failure.)

On Mac OS X:

sudo find / -name postgresql.conf 

You can find other conf files by the following command:

sudo find / -name pg\*.conf

Note: See usage using man:

man find

New Note: You probably don't want or need to do this. What you probably want to do is just put those types of command dependencies for build/test etc. in the devDependencies section of your package.json. Anytime you use something from scripts in package.json your devDependencies commands (in node_modules/.bin) act as if they are in your path.

For example:

npm i --save-dev mocha # Install test runner locally
npm i --save-dev babel # Install current babel locally

Then in package.json:

// devDependencies has mocha and babel now

"scripts": {
  "test": "mocha",
  "build": "babel -d lib src",
  "prepublish": "babel -d lib src"
}

Then at your command prompt you can run:

npm run build # finds babel
npm test # finds mocha

npm publish # will run babel first

But if you really want to install globally, you can add a preinstall in the scripts section of the package.json:

"scripts": {
  "preinstall": "npm i -g themodule"
}

So actually my npm install executes npm install again .. which is weird but seems to work.

Note: you might have issues if you are using the most common setup for npm where global Node package installs required sudo. One option is to change your npm configuration so this isn't necessary:

npm config set prefix ~/npm, add $HOME/npm/bin to $PATH by appending export PATH=$HOME/npm/bin:$PATH to your ~/.bashrc.

JDBC is a much lower-level (and older) specification than JPA. In it's bare essentials, JDBC is an API for interacting with a database using pure SQL - sending queries and retrieving results. It has no notion of objects or hierarchies. When using JDBC, it's up to you to translate a result set (essentially a row/column matrix of values from one or more database tables, returned by your SQL query) into Java objects.

Now, to understand and use JDBC it's essential that you have some understanding and working knowledge of SQL. With that also comes a required insight into what a relational database is, how you work with it and concepts such as tables, columns, keys and relationships. Unless you have at least a basic understanding of databases, SQL and data modelling you will not be able to make much use of JDBC since it's really only a thin abstraction on top of these things.

No Go doesn't have a ternary operator, using if/else syntax is the idiomatic way.

Why does Go not have the ?: operator?

There is no ternary testing operation in Go. You may use the following to achieve the same result:

if expr {
    n = trueVal
} else {
    n = falseVal
}

The reason ?: is absent from Go is that the language's designers had seen the operation used too often to create impenetrably complex expressions. The if-else form, although longer, is unquestionably clearer. A language needs only one conditional control flow construct.

— Frequently Asked Questions (FAQ) - The Go Programming Language

bless associates a reference with a package.

It doesn't matter what the reference is to, it can be to a hash (most common case), to an array (not so common), to a scalar (usually this indicates an inside-out object), to a regular expression, subroutine or TYPEGLOB (see the book Object Oriented Perl: A Comprehensive Guide to Concepts and Programming Techniques by Damian Conway for useful examples) or even a reference to a file or directory handle (least common case).

The effect bless-ing has is that it allows you to apply special syntax to the blessed reference.

For example, if a blessed reference is stored in $obj (associated by bless with package "Class"), then $obj->foo(@args) will call a subroutine foo and pass as first argument the reference $obj followed by the rest of the arguments (@args). The subroutine should be defined in package "Class". If there is no subroutine foo in package "Class", a list of other packages (taken form the array @ISA in the package "Class") will be searched and the first subroutine foo found will be called.

If you want a better experience when creating your Virtual Device, use "Store a snapshot for faster startup" instead of the default "Use Host GPU".

Personnaly I encountered this issue while migrating a IIS6 website into IIS7, in order to fix this issue I used this command line :
%windir%\System32\inetsrv\appcmd migrate config "MyWebSite\"
Make sure to backup your web.config

You haven't got your SUMIF in the correct order - it needs to be range, criteria, sum range. Try:

=SUMIF(A:A,">="&DATE(2012,1,1),B:B)

I have a code shared between server and client and I needed an implementation of btoa inside it. I tried doing something like:

const btoaImplementation =  btoa || (str => Buffer.from(str).toString('base64'));

but the Server would crush with:

ReferenceError: btoa is not defined

while Buffer is not defined on the client.

I couldn't check window.btoa (it's a shared code, remember?)

So I ended up with this implementation:

const btoaImplementation = str => {
    try {
        return btoa(str);
    } catch(err) {
        return Buffer.from(str).toString('base64')
    }
};

It causes the error when you access $(this).val() when it called by change event this points to the invoker i.e. CourseSelect so it is working and and will get the value of CourseSelect. but when you manually call it this points to document. so either you will have to pass the CourseSelect object or access directly like $("#CourseSelect").val() instead of $(this).val().

Yet another approach is ISNULL().

UPDATE [DATABASE].[dbo].[TABLE_NAME]
SET    
    [ABC]  = ISNULL(@ABC, [ABC]),
    [ABCD] = ISNULL(@ABCD, [ABCD])

The difference between ISNULL and COALESCE is the return type. COALESCE can also take more than 2 arguments, and use the first that is not null. I.e.

select COALESCE(null, null, 1, 'two') --returns 1
select COALESCE(null, null, null, 'two') --returns 'two'

Attach a Spinner Style using Java Code:

First, you need to a layout file such as below:

<?xml version="1.0" encoding="utf-8"?><TextView xmlns:android="http://schemas.android.com/apk/res/android"
android:id="@android:id/text1"
style="?android:attr/spinnerDropDownItemStyle"
android:layout_width="match_parent"
android:layout_height="wrap_content"
android:ellipsize="none"
android:minHeight="?android:attr/listPreferredItemHeight" />

Let us name it spinner_item.xml and place it inside res/layouts folder.

Next, Create a String ArrayList and put all the Spinner options inside it:

ArrayList<String> spinnerArray = new ArrayList<String>();
spinnerArray.add("Item No. 1");
spinnerArray.add("Item No. 2");
spinnerArray.add("Item No. 3");
spinnerArray.add("Item No. 4");

Finally, create the Spinner object and attach the style layout to it.

Spinner spinner = new Spinner(getActivity());
spinner.setTag("some_id");
ArrayAdapter<String> spinnerArrayAdapter = new ArrayAdapter<String>(getActivity(), android.R.layout.simple_spinner_dropdown_item, spinnerArray);                  spinnerArrayAdapter.setDropDownViewResource(R.layout.spinner_item);
spinner.setAdapter(spinnerArrayAdapter);

Note the Spinner(getActivity()) in the above line will be changed to Spinner(this) if you are writing this from inside Activity rather than from inside a fragment.

Thats all!

Attach a Spinner Style inside Android Layout File:

First, create a xml file the defines the style attribute (gradient_spinner.xml)

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

    <item><layer-list>
        <item><shape>
            <gradient android:angle="90"  android:type="linear" />

            <stroke android:width="1dp" android:color="@color/colorBackground" />

            <corners android:radius="2dp" />

            <padding android:bottom="1dp" android:left="1dp" android:right="1dp" android:top="1dp" />
        </shape></item>
        <item android:right="5dp">
            <bitmap android:gravity="center_horizontal|right" android:src="@drawable/expand_icon">
            <padding android:right="2dp" />
        </bitmap>
        </item>
    </layer-list></item>

</selector>

Next, inside the style.xml file specify the style and call the gradient_spinner as background

<style name="spinner_style">
<item name="android:layout_width">match_parent</item>
<item name="android:layout_height">wrap_content</item>
<item name="android:background">@drawable/gradient_spinner</item>
<item name="android:layout_margin">1dp</item>
<item name="android:paddingLeft">5dp</item>
<item name="android:paddingRight">5dp</item>
<item name="android:paddingTop">5dp</item>
<item name="android:paddingBottom">5dp</item>
</style>

Finally, attach the above style to the Spinner:

<Spinner
   android:id="@+id/agent_id_spinner"
   android:layout_width="match_parent"
   android:layout_height="40dp"
   android:textSize="@dimen/title_text_view"
   style="@style/spinner_style"  />

Thats it!

If you use RGBA for modern browsers you don't need let older IEs use only the non-transparent version of the given color with RGB.

If you don't stick to CSS-only solutions, give CSS3PIE a try. With this syntax you can see exactly the same result in older IEs that you see in modern browsers:

div {
    -pie-background: rgba(223,231,233,0.8);
    behavior: url(../PIE.htc);
}

Other option, for similar example but with anidated selects, think that you have two select, the name of the first is "ea_pub_dest" and the name of the second is "ea_pub_dest_2", ok, now take the event click of the first and display the second.

<script>

function test()
{
    value = document.getElementById("ea_pub_dest").value;
    if ( valor == "value_1" )
        document.getElementById("ea_pub_dest_nivel").style.display = "block";
}
</script>

The easiest is

as @greggo pointed out

string="mystring";
string[:-1]

I followed almost the same instructions by @Mason G. Zhwiti , but had to instead navigate to this folder to find the SDK:

In my case, I needed to Edit Inbound Rules on my AWS RDS instance to accept All Traffic. The default TCP/IP constraint prevented me from creating a database from my local machine otherwise.

try using concatenation of string

Statistics(string date)
    {
        this->date += date;
    }

acually this was a part of a class..

I like the solution using the -eq test, because it's basically a one-liner.

My own solution was to use parameter expansion to throw away all the numerals and see if there was anything left. (I'm still using 3.0, haven't used [[ or expr before, but glad to meet them.)

if [ "${INPUT_STRING//[0-9]}" = "" ]; then
  # yes, natural number
else
  # no, has non-numeral chars
fi

You may choose to store the whole form as a JSON string.

Not sure about your requirement, but this approach would work in some circumstances.

On windows run "cmd " as administrator and execute command.

"C:\Program Files\Git\mingw64\etc>"
"git config --system core.longpaths true"

or you have to chmod for the folder whereever git is installed.

or manullay update your file manually by going to path "Git\mingw64\etc"

I found that DataGridViewTextBox values and some JSON objects don't equal Null but instead are "{}" values. Comparing them to Null doesn't work but using these do the trick:

if (cell.Value is System.DBNull)

if (cell.Value == System.DBNull.Value)

A good excerpt I found concerning the difference between Null and DBNull:

Do not confuse the notion of null in an object-oriented programming language with a DBNull object. In an object-oriented programming language, null means the absence of a reference to an object. DBNull represents an uninitialized variant or nonexistent database column.

You can learn more about the DBNull class here.

Just to be really clear, this has nothing to do with enumerate and everything to do with list comprehension syntax.

This list comprehension returns a list of tuples:

[(i,j) for i in range(3) for j in 'abc']

this a list of dicts:

[{i:j} for i in range(3) for j in 'abc']

a list of lists:

[[i,j] for i in range(3) for j in 'abc']

a syntax error:

[i,j for i in range(3) for j in 'abc']

Which is inconsistent (IMHO) and confusing with dictionary comprehensions syntax:

>>> {i:j for i,j in enumerate('abcdef')}
{0: 'a', 1: 'b', 2: 'c', 3: 'd', 4: 'e', 5: 'f'}

And a set of tuples:

>>> {(i,j) for i,j in enumerate('abcdef')}
set([(0, 'a'), (4, 'e'), (1, 'b'), (2, 'c'), (5, 'f'), (3, 'd')])

As Óscar López stated, you can just pass the enumerate tuple directly:

>>> [t for t in enumerate('abcdef') ] 
[(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd'), (4, 'e'), (5, 'f')]

break is used when you want to exit from the loop, while return is used to go back to the step where it was called or to stop further execution.

I had the same problem, then I found out that I had duplicate api controller class names in other project and despite the fact that the "routePrefix" and namespace and project name were different but still they returned 404, I changed the class names and it worked.

you can't force refresh but you can forward all old ip requests to new one. for a website:

replace [OLD_IP] with old server's ip

replace [NEW_IP] with new server's ip

run & win.

echo "1" > /proc/sys/net/ipv4/ip_forward

iptables -t nat -A PREROUTING -d [OLD_IP] -p tcp --dport 80 -j DNAT --to-destination [NEW_IP]:80

iptables -t nat -A PREROUTING -d [OLD_IP] -p tcp --dport 443 -j DNAT --to-destination [NEW_IP]:443

@Baba's answer is great. But you don't need to use explode because fputcsv takes an array as a parameter

For instance, if you have a three columns, four lines document, here's a more straight version:

header('Content-Type: text/csv');
header('Content-Disposition: attachment; filename="sample.csv"');

$user_CSV[0] = array('first_name', 'last_name', 'age');

// very simple to increment with i++ if looping through a database result 
$user_CSV[1] = array('Quentin', 'Del Viento', 34);
$user_CSV[2] = array('Antoine', 'Del Torro', 55);
$user_CSV[3] = array('Arthur', 'Vincente', 15);

$fp = fopen('php://output', 'wb');
foreach ($user_CSV as $line) {
    // though CSV stands for "comma separated value"
    // in many countries (including France) separator is ";"
    fputcsv($fp, $line, ',');
}
fclose($fp);

I found an extension method that works quite well

public static string ToHex(this Color color)
{
    return String.Format("#{0}{1}{2}{3}"
        , color.A.ToString("X").Length == 1 ? String.Format("0{0}", color.A.ToString("X")) : color.A.ToString("X")
        , color.R.ToString("X").Length == 1 ? String.Format("0{0}", color.R.ToString("X")) : color.R.ToString("X")
        , color.G.ToString("X").Length == 1 ? String.Format("0{0}", color.G.ToString("X")) : color.G.ToString("X")
        , color.B.ToString("X").Length == 1 ? String.Format("0{0}", color.B.ToString("X")) : color.B.ToString("X"));
}

It may be

select timediff(current_time(),utc_time())

You won't get the timezone value directly this way.

@@global.time_zone cannot be used as it is a variable, and it returns the value 'SYSTEM'.

If you need to use your query in a session with a changed timezone by using session SET TIME_ZONE =, then you will get that with @@session.time_zone. If you query @@global.time_zone, then you get 'SYSTEM'.

If you try datediff, date_sub, or timediff with now() and utc_time(), then you'll probably run into conversion issues.

But the things suggested above will probably work at least with some server versions. My version is 5.5.43-37 and is a hosted solution.

If you are on the first line, pressing (upper case) J will join that line and the next line together, removing the newline. You can also combine this with a count, so pressing 3J will combine all 3 lines together.

With the cli I don't know if it's a remove command but you can remove it from package.json and stop using it in your code.If you reinstall the packages you wilk not have it any more

You can have a look at this library: https://github.com/mozilla/pdf.js it renders PDF document in a Web/HTML page

Also you can use Flash to embed the document into any HTML page like that:

<object data="your_file.pdf#view=Fit" type="application/pdf" width="100%" height="850">
    <p>
        It appears your Web browser is not configured to display PDF files. No worries, just <a href="your_file.pdf">click here to download the PDF file.</a>

Here's the solution I've come up with:

private static final Comparator<Integer> BY_ASCENDING_ORDER = Integer::compare;
private static final Comparator<Integer> BY_DESCENDING_ORDER = BY_ASCENDING_ORDER.reversed();

then using those comparators:

IntStream.range(-range, 0).boxed().sorted(BY_DESCENDING_ORDER).forEach(// etc...

echo "1 2 3 4 5 6" | awk '{ $NF = ""; print $0}'

this one uses awk to print all except the last field

Eclipse Neon (4.6), release date June 2016, includes word wrap for text editors. It's disabled by default, and can be activated and deactivated using the key shortcut Alt+Shift+Y (on Mac OS, Cmd-Opt-Y). Some editors also supply a tool bar button for activating word wrap.

It's very easy to write that yourself, and that way you have more control over things.. As the other answers say, TypeScript is not aimed at adding runtime types or functionality.

Map:

class Map<T> {
    private items: { [key: string]: T };

    constructor() {
        this.items = {};
    }

    add(key: string, value: T): void {
        this.items[key] = value;
    }

    has(key: string): boolean {
        return key in this.items;
    }

    get(key: string): T {
        return this.items[key];
    }
}

List:

class List<T> {
    private items: Array<T>;

    constructor() {
        this.items = [];
    }

    size(): number {
        return this.items.length;
    }

    add(value: T): void {
        this.items.push(value);
    }

    get(index: number): T {
        return this.items[index];
    }
}

I haven't tested (or even tried to compile) this code, but it should give you a starting point.. you can of course then change what ever you want and add the functionality that YOU need...

As for your "special needs" from the List, I see no reason why to implement a linked list, since the javascript array lets you add and remove items.
Here's a modified version of the List to handle the get prev/next from the element itself:

class ListItem<T> {
    private list: List<T>;
    private index: number;

    public value: T;

    constructor(list: List<T>, value: T, index: number) {
        this.list = list;
        this.index = index;
        this.value = value;
    }

    prev(): ListItem<T> {
        return this.list.get(this.index - 1);
    }

    next(): ListItem<T> {
        return this.list.get(this.index + 1);   
    }
}

class List<T> {
    private items: Array<ListItem<T>>;

    constructor() {
        this.items = [];
    }

    size(): number {
        return this.items.length;
    }

    add(value: T): void {
        this.items.push(new ListItem<T>(this, value, this.size()));
    }

    get(index: number): ListItem<T> {
        return this.items[index];
    }
}

Here too you're looking at untested code..

Hope this helps.

Edit - as this answer still gets some attention

Javascript has a native Map object so there's no need to create your own:

let map = new Map();
map.set("key1", "value1");
console.log(map.get("key1")); // value1

You can see this example.

// Is this element visible onscreen?
var visible = $(#element).visible( detectPartial );

detectPartial :

• True : the entire element is visible
• false : part of the element is visible

visible is boolean variable which indicates if the element is visible or not.

Django provides it. You can use either:

• {{ forloop.counter }} index starts at 1.
• {{ forloop.counter0 }} index starts at 0.

In template, you can do:

{% for item in item_list %}
    {{ forloop.counter }} # starting index 1
    {{ forloop.counter0 }} # starting index 0

    # do your stuff
{% endfor %}

More info at: for | Built-in template tags and filters | Django documentation

Okay this will work 100% for sure.

First you will need to setup listener if keyboard is show or hide. If keyboard is showing then probably user is typing, otherwise done typing.

final View activityRootView = findViewById(android.R.id.content);
        activityRootView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
            @Override
            public void onGlobalLayout() {

                    Rect r = new Rect();
                    //r will be populated with the coordinates of your view that area still visible.
                    activityRootView.getWindowVisibleDisplayFrame(r);

                    int heightDiff = activityRootView.getRootView().getHeight() - (r.bottom - r.top);
                    if (heightDiff > 100) { // if more than 100 pixels, its probably a keyboard...

                        isTyping = true;
                    } else {
//to make sure this will call only once when keyboard is hide.
                        if(isTyping){
                            isTyping = false;
                        }
                    }
            }
        });

1. you can Use Window Or Linux Os

   import os
   os.system('cls')
   os.system('clear')
   

2. you can use subprocess module

   import subprocess as sp
   x=sp.call('cls',shell=True)
   

Use your bean class like this, if your JSON data starts with an an array object. it helps you.

Users[] bean = gson.fromJson(response,Users[].class);

Users is my bean class.

Response is my JSON data.

public static boolean stringToBool(String s) {
        s = s.toLowerCase();
        Set<String> trueSet = new HashSet<String>(Arrays.asList("1", "true", "yes"));
        Set<String> falseSet = new HashSet<String>(Arrays.asList("0", "false", "no"));

        if (trueSet.contains(s))
            return true;
        if (falseSet.contains(s))
            return false;

        throw new IllegalArgumentException(s + " is not a boolean.");
    }

My way to convert string to boolean.

If I were you and wanted to do so, I wouldn't use my User entity in Controller layer.Instead I create and use UserDto (Data transfer object) to communicate with business(Service) layer and Controller. You can use Apache BeanUtils(copyProperties method) to copy data from User entity to UserDto.

I've solved this problem by configuring MySQL.

SET GLOBAL time_zone = '+3:00';

This is working for me, as described in this thread:

declare let something: string;
something = 'foo';

It's not the best answer, but its also an option: since you can concatenate multiple expressions, but just the last one is rendered, you can finish your expression with "" and your variable will be hidden.

So, you could define the variable with:

{{f = forecast[day.iso]; ""}}

ifstream inFile;
string name, temp;
int age;

inFile.open("file.txt");

getline(inFile, name, ' '); // use ' ' as separator, default is '\n' (newline). Now name is "John".
getline(inFile, temp, ' '); // Now temp is "Smith"
name.append(1,' ');
name += temp;
inFile >> age; 

cout << name << endl;
cout << age << endl;  

inFile.close();    

You can give the Open Hardware Monitor a go, although it lacks support for the latest processors.

internal sealed class CpuTemperatureReader : IDisposable
{
    private readonly Computer _computer;

    public CpuTemperatureReader()
    {
        _computer = new Computer { CPUEnabled = true };
        _computer.Open();
    }

    public IReadOnlyDictionary<string, float> GetTemperaturesInCelsius()
    {
        var coreAndTemperature = new Dictionary<string, float>();

        foreach (var hardware in _computer.Hardware)
        {
            hardware.Update(); //use hardware.Name to get CPU model
            foreach (var sensor in hardware.Sensors)
            {
                if (sensor.SensorType == SensorType.Temperature && sensor.Value.HasValue)
                    coreAndTemperature.Add(sensor.Name, sensor.Value.Value);
            }
        }

        return coreAndTemperature;
    }

    public void Dispose()
    {
        try
        {
            _computer.Close();
        }
        catch (Exception)
        {
            //ignore closing errors
        }
    }
}

Download the zip from the official source, extract and add a reference to OpenHardwareMonitorLib.dll in your project.

For just one run (from the unix shell prompt):

$ PORT=1234 node app.js

More permanently:

$ export PORT=1234
$ node app.js

In Windows:

set PORT=1234

In Windows PowerShell:

$env:PORT = 1234

If you think about it, comparing numbers to logical statements doesn't make much sense. However, since 0 is often associated with "Off" or "False" and 1 with "On" or "True", R has decided to allow 1 == TRUE and 0 == FALSE to both be true. Any other numeric-to-boolean comparison should yield false, unless it's something like 3 - 2 == TRUE.

Your code can be narrowed down to

Sub DeleteTableRows(ByRef Table As ListObject)
    On Error Resume Next
    '~~> Clear Header Row `IF` it exists
    Table.DataBodyRange.Rows(1).ClearContents
    '~~> Delete all the other rows `IF `they exist
    Table.DataBodyRange.Offset(1, 0).Resize(Table.DataBodyRange.Rows.Count - 1, _
    Table.DataBodyRange.Columns.Count).Rows.Delete
    On Error GoTo 0
End Sub

Edit:

On a side note, I would add proper error handling if I need to intimate the user whether the first row or the other rows were deleted or not

what i did to restore the scroll position after refreshing the RecyclerView on button clicked:

if (linearLayoutManager != null) {

    index = linearLayoutManager.findFirstVisibleItemPosition();
    View v = linearLayoutManager.getChildAt(0);
    top = (v == null) ? 0 : (v.getTop() - linearLayoutManager.getPaddingTop());
    Log.d("TAG", "visible position " + " " + index);
}

else{
    index = 0;
}

linearLayoutManager = new LinearLayoutManager(getApplicationContext());
linearLayoutManager.scrollToPositionWithOffset(index, top);

getting the offset of the first visible item from the top before creating the linearLayoutManager object and after instantiating it the scrollToPositionWithOffset of the LinearLayoutManager object was called.

The simplest way I found:

git branch -a

There is DatePicker in WPF Tool Kit, but I have not seen DateTime Picker in WPF ToolKit. So I don't know what kind of DateTimePicker control John is talking about.

properties have a specific meaning in Objective-C, but I think you mean something that's equivalent to a static variable? E.g. only one instance for all types of Foo?

To declare class functions in Objective-C you use the + prefix instead of - so your implementation would look something like:

// Foo.h
@interface Foo {
}

+ (NSDictionary *)dictionary;

// Foo.m
+ (NSDictionary *)dictionary {
  static NSDictionary *fooDict = nil;
  if (fooDict == nil) {
    // create dict
  }
  return fooDict;
}

This is how you can find the latitude and longitude of where we have click on map.

public boolean onTouchEvent(MotionEvent event, MapView mapView) 
{   
    //---when user lifts his finger---
    if (event.getAction() == 1) 
    {                
        GeoPoint p = mapView.getProjection().fromPixels(
            (int) event.getX(),
            (int) event.getY());

        Toast.makeText(getBaseContext(), 
             p.getLatitudeE6() / 1E6 + "," + 
             p.getLongitudeE6() /1E6 , 
             Toast.LENGTH_SHORT).show();
    }                            
    return false;
} 

it works well.

To get the location's address we can use geocoder class.

You should check out this plugin:

and the demo:

if anything, you might be able to borrow some code from it to fix yours.

I think a really simple answer might be useful here:

return makes the value (a variable, often) available for use by the caller (for example, to be stored by a function that the function using return is within). Without return, your value or variable wouldn't be available for the caller to store/re-use.

print prints to the screen, but does not make the value or variable available for use by the caller.

(Fully admitting that the more thorough answers are more accurate.)

The easiest way to do this is just: You will receive a float or double and want it to convert it to the closest round up then just do System.out.println((int)Math.ceil(yourfloat)); it'll work perfectly

It may be obvious, but it still was surprising to me, that SET NAMES utf8 is not compatible with utf8mb4 encoding. So for some apps changing table/column encoding was not enough. I had to change encoding in app configuration.

Redmine (ruby, ROR)

In config/database.yml:

production:
  adapter: mysql2
  database: redmine
  host: localhost
  username: redmine
  password: passowrd
  encoding: utf8mb4

Custom Yii application (PHP)

In config/db.php:

return [
    'class' => yii\db\Connection::class,
    'dsn' => 'mysql:host=localhost;dbname=yii',
    'username' => 'yii',
    'password' => 'password',
    'charset' => 'utf8mb4',
],

If you have utf8mb4 as a column/table encoding and still getting errors like this, make sure that you have configured correct charset for DB connection in your application.

Java 8 version:

    public static long countNumberOfOccurrencesOfWordInString(String msg, String target) {
    return Arrays.stream(msg.split("[ ,\\.]")).filter(s -> s.equals(target)).count();
}

You can do this by just changing the html. Here's an example:

<hmtl>
  <head>
    <title>Some title</title>
  </head>
  <body> 
  <map name="navigatemap">
    <area shape="rect"  
          coords="166,4,319,41" 
          href="WII.htm"  
          onMouseOut="navbar.src='Assets/NavigationBar(OnHome).png'" 
          onMouseOver="navbar.src='Assets/NavigationBar(OnHome,MouseOverWII).png'" 
    />
    <area shape="rect"
          coords="330,4,483,41" 
          href="OT.htm"  
          onMouseOut="navbar.src='Assets/NavigationBar(OnHome).png'" 
          onMouseOver="navbar.src='Assets/NavigationBar(OnHome,MouseOverOT).png'" 
    />

    <area shape="rect" 
          coords="491,3,645,41" 
          href="OP.htm"  
          onMouseOut="navbar.src='Assets/NavigationBar(OnHome).png'" 
          onMouseOver="navbar.src='Assets/NavigationBar(OnHome,MouseOverOP).png'" 
   />
  </map> 

  <img src="Assets/NavigationBar(OnHome).png" 
     name="navbar" 
     usemap="#navigatemap" />
  </body>
</html>

As an explanation to Jonathan Fingland's answer:

• multiple conditions in the same predicate ([position()=1 and @location='US']) must be true as a whole
• multiple conditions in consecutive predicates ([position()=1][@location='US']) must be true one after another
• this implies that [position()=1][@location='US'] != [@location='US'][position()=1]
  while [position()=1 and @location='US'] == [@location='US' and position()=1]
• hint: a lone [position()=1] can be abbreviated to [1]

You can build complex expressions in predicates with the Boolean operators "and" and "or", and with the Boolean XPath functions not(), true() and false(). Plus you can wrap sub-expressions in parentheses.

One way can be to circularly store the values in the buffer array. and calculate average this way.

int j = (int) (counter % size);
buffer[j] = mostrecentvalue;
avg = (avg * size - buffer[j - 1 == -1 ? size - 1 : j - 1] + buffer[j]) / size;

counter++;

// buffer[j - 1 == -1 ? size - 1 : j - 1] is the oldest value stored

The whole thing runs in a loop where most recent value is dynamic.

Because there are two print statements. First is inside function and second is outside function. When function not return any thing that time it return None value.

Use return statement at end of function to return value.

e.g.:

Return None value.

>>> def test1():
...    print "In function."
... 
>>> a = test1()
In function.
>>> print a
None
>>> 
>>> print test1()
In function.
None
>>>
>>> test1()
In function.
>>> 

Use return statement

>>> def test():
...   return "ACV"
... 
>>> print test()
ACV
>>> 
>>> a = test()
>>> print a
ACV
>>>

You could skip the use of buttord, and instead just pick an order for the filter and see if it meets your filtering criterion. To generate the filter coefficients for a bandpass filter, give butter() the filter order, the cutoff frequencies Wn=[low, high] (expressed as the fraction of the Nyquist frequency, which is half the sampling frequency) and the band type btype="band".

Here's a script that defines a couple convenience functions for working with a Butterworth bandpass filter. When run as a script, it makes two plots. One shows the frequency response at several filter orders for the same sampling rate and cutoff frequencies. The other plot demonstrates the effect of the filter (with order=6) on a sample time series.

from scipy.signal import butter, lfilter


def butter_bandpass(lowcut, highcut, fs, order=5):
    nyq = 0.5 * fs
    low = lowcut / nyq
    high = highcut / nyq
    b, a = butter(order, [low, high], btype='band')
    return b, a


def butter_bandpass_filter(data, lowcut, highcut, fs, order=5):
    b, a = butter_bandpass(lowcut, highcut, fs, order=order)
    y = lfilter(b, a, data)
    return y


if __name__ == "__main__":
    import numpy as np
    import matplotlib.pyplot as plt
    from scipy.signal import freqz

    # Sample rate and desired cutoff frequencies (in Hz).
    fs = 5000.0
    lowcut = 500.0
    highcut = 1250.0

    # Plot the frequency response for a few different orders.
    plt.figure(1)
    plt.clf()
    for order in [3, 6, 9]:
        b, a = butter_bandpass(lowcut, highcut, fs, order=order)
        w, h = freqz(b, a, worN=2000)
        plt.plot((fs * 0.5 / np.pi) * w, abs(h), label="order = %d" % order)

    plt.plot([0, 0.5 * fs], [np.sqrt(0.5), np.sqrt(0.5)],
             '--', label='sqrt(0.5)')
    plt.xlabel('Frequency (Hz)')
    plt.ylabel('Gain')
    plt.grid(True)
    plt.legend(loc='best')

    # Filter a noisy signal.
    T = 0.05
    nsamples = T * fs
    t = np.linspace(0, T, nsamples, endpoint=False)
    a = 0.02
    f0 = 600.0
    x = 0.1 * np.sin(2 * np.pi * 1.2 * np.sqrt(t))
    x += 0.01 * np.cos(2 * np.pi * 312 * t + 0.1)
    x += a * np.cos(2 * np.pi * f0 * t + .11)
    x += 0.03 * np.cos(2 * np.pi * 2000 * t)
    plt.figure(2)
    plt.clf()
    plt.plot(t, x, label='Noisy signal')

    y = butter_bandpass_filter(x, lowcut, highcut, fs, order=6)
    plt.plot(t, y, label='Filtered signal (%g Hz)' % f0)
    plt.xlabel('time (seconds)')
    plt.hlines([-a, a], 0, T, linestyles='--')
    plt.grid(True)
    plt.axis('tight')
    plt.legend(loc='upper left')

    plt.show()

Here are the plots that are generated by this script:

This is a simpler one

$('#some_select_box').find('option:selected').remove().end();

Open mainstoryboard, select the view that you want start first, then open Utilities--> Attributes. Below the "View Controller" you see the "Is initial View Controller" radio button. Just select it.

--- To the revised question:

May be you can try this: write a method in ViewDidLoad section of your inital view and when the method runs on application launch, method triggers a segue to another view.

For Bootstrap 3:

$('.nav-tabs a[href="#' + tabID + '"]').tab('show');

Your original code uses FileInputStream, which is for accessing file system hosted files.

The constructor you used will attempt to locate a file named a.txt in the www.somewebsite.com subfolder of the current working directory (the value of system property user.dir). The name you provide is resolved to a file using the File class.

URL objects are the generic way to solve this. You can use URLs to access local files but also network hosted resources. The URL class supports the file:// protocol besides http:// or https:// so you're good to go.

Assuming you're in control of the pattern used to find test classes, I'd suggest changing it to match *Test rather than *Test*. That way TestHelper won't get matched, but FooTest will.

Use CultureInfo class to change your culture info.

var dutchCultureInfo = CultureInfo.CreateSpecificCulture("nl-NL");
var date1 = DateTime.ParseExact(date, "dd.MM.yyyy HH:mm:ss", dutchCultureInfo);

You can use the extension method of Request:

Request.GetDisplayUrl()

I know this question already has an accepted answer, but for me, a .NET beginner, there was a simple solution to what I was doing wrong and I thought I'd share.

I had been doing this:

@Html.HiddenFor(Model.Foo.Bar.ID)

What worked for me was changing to this:

@Html.HiddenFor(m => m.Foo.Bar.ID)

(where "m" is an arbitrary string to represent the model object)

HttpURLConnection:

URL url = new URL("http://example.com");
HttpURLConnection connection = (HttpURLConnection)url.openConnection();
connection.setRequestMethod("GET");
connection.connect();

int code = connection.getResponseCode();

This is by no means a robust example; you'll need to handle IOExceptions and whatnot. But it should get you started.

If you need something with more capability, check out HttpClient.

When you generate a JAXB model from an XML Schema, global elements that correspond to named complex types will have that metadata captured as an @XmlElementDecl annotation on a create method in the ObjectFactory class. Since you are creating the JAXBContext on just the DocumentType class this metadata isn't being processed. If you generated your JAXB model from an XML Schema then you should create the JAXBContext on the generated package name or ObjectFactory class to ensure all the necessary metadata is processed.

Example solution:

JAXBContext jaxbContext = JAXBContext.newInstance(my.generatedschema.dir.ObjectFactory.class);
DocumentType documentType = ((JAXBElement<DocumentType>) jaxbContext.createUnmarshaller().unmarshal(inputStream)).getValue();

you use bad character like ? and & and etc ...

TL;DR:

socket.send(data, callback) is essentially equivalent to calling socket.emit('message', JSON.stringify(data), callback)

Without looking at the source code, I would assume that the send function is more efficient edit: for sending string messages, at least?

So yeah basically emit allows you to send objects, which is very handy.

Take this example with socket.emit:

sendMessage: function(type, message) {
    socket.emit('message', {
        type: type,
        message: message
    });
}

and for those keeping score at home, here is what it looks like using socket.send:

sendMessage: function(type, message) {
    socket.send(JSON.stringify({
        type: type,
        message: message
    }));
}

It'll be because response[0] itself is undefined.

An alternative way of approaching this problem is to use data attributes, which are by nature unique.

You'd set the colour of an element like: $el.attr('data-color', 'red');

And you'd style it in css like: [data-color="red"]{ color: tomato; }

This negates the need for using classes, which has the side-effect of needing to remove old classes.

It sounds very much like you're using an array to store different fields. This is definitely a code smell. I'd avoid using arrays as much as possible as they're generally not suitable (or needed) in high-level code.

Switching to a simple Dictionary may be a workable option in the short term. As would using a big property bag class. There are lots of options. The problem you have now is just a symptom of bad design, you should look at fixing the underlying problem rather than just patching the bad design so it kinda, sorta mostly works, for now.

        axios.get(
            '/app/export'
        ).then(response => {    
            const url = window.URL.createObjectURL(new Blob([response]));
            const link = document.createElement('a');
            link.href = url;
            const fileName = `${+ new Date()}.csv`// whatever your file name .
            link.setAttribute('download', fileName);
            document.body.appendChild(link);
            link.click();
            link.remove();// you need to remove that elelment which is created before.
})

CLOSE_WAIT means your program is still running, and hasn't closed the socket (and the kernel is waiting for it to do so). Add -p to netstat to get the pid, and then kill it more forcefully (with SIGKILL if needed). That should get rid of your CLOSE_WAIT sockets. You can also use ps to find the pid.

SO_REUSEADDR is for servers and TIME_WAIT sockets, so doesn't apply here.

#include <stdio.h>

int main () {

   int i, j;

   for(i = 2; i<100; i++) {

      for(j = 2; j <= (i/j); j++) 
      if(!(i%j)) break; // if factor found, not prime
      if(j > (i/j)) printf("%d is prime", i);
   }

   return 0;
}

Here is a procedure and code using generated ProjectInstaller in Visual Studio:

1. Create Windows Service project in Visual Studio
2. Generate installers to the service
3. Open ProjectInstaller in design editor (it should open automatically when installer is created) and set properties of generated serviceProcessInstaller1 (e.g. Account: LocalSystem) and serviceInstaller1 (e.g. StartType: Automatic)
4. Open ProjectInstaller in code editor (press F7 in design editor) and add event handler to ServiceInstaller.AfterInstall - see the following code. It will start the service after its installation.

ProjectInstaller class:

using System.ServiceProcess;


[RunInstaller(true)]
public partial class ProjectInstaller : System.Configuration.Install.Installer
{
    public ProjectInstaller()
    {
        InitializeComponent(); //generated code including property settings from previous steps
        this.serviceInstaller1.AfterInstall += Autorun_AfterServiceInstall; //use your ServiceInstaller name if changed from serviceInstaller1
    }

    void Autorun_AfterServiceInstall(object sender, InstallEventArgs e)
    {
        ServiceInstaller serviceInstaller = (ServiceInstaller)sender;
        using (ServiceController sc = new ServiceController(serviceInstaller.ServiceName))
        {
            sc.Start();
        }
    }
}

You basically need to make a HTTP request to the service, and then parse the body of the response. I like to use httplib2 for it:

import httplib2 as http
import json

try:
    from urlparse import urlparse
except ImportError:
    from urllib.parse import urlparse

headers = {
    'Accept': 'application/json',
    'Content-Type': 'application/json; charset=UTF-8'
}

uri = 'http://yourservice.com'
path = '/path/to/resource/'

target = urlparse(uri+path)
method = 'GET'
body = ''

h = http.Http()

# If you need authentication some example:
if auth:
    h.add_credentials(auth.user, auth.password)

response, content = h.request(
        target.geturl(),
        method,
        body,
        headers)

# assume that content is a json reply
# parse content with the json module
data = json.loads(content)

The module needs to be placed in a folder with the same name as the module. In your case:

$home/WindowsPowerShell/Modules/XMLHelpers/

The full path would be:

$home/WindowsPowerShell/Modules/XMLHelpers/XMLHelpers.psm1

You would then be able to do:

import-module XMLHelpers

The solution I use is the following:

<input list="answers" id="answer">
<datalist id="answers">
  <option data-value="42" value="The answer">
</datalist>

Then access the value to be sent to the server using JavaScript like this:

var shownVal = document.getElementById("answer").value;
var value2send = document.querySelector("#answers option[value='"+shownVal+"']").dataset.value;

Hope it helps.

You can declare the function pointer as follows:

bool (funptr*)();

Which says we are declaring a function pointer to a function which does not take anything and return a bool.

Next assignment:

funptr = A;

To call the function using the function pointer:

funptr();

Here's a simple unix2dos.bat file that preserves blank lines and exclamation points:

@echo off
setlocal DisableDelayedExpansion
for /f "tokens=1,* delims=:" %%k in ('findstr /n "^" %1') do echo.%%l

The output goes to standard out, so redirect unix2dos.bat output to a file if so desired.

It avoids the pitfalls of other previously proposed for /f batch loop solutions by:
1) Working with delayed expansion off, to avoid eating up exclamation marks.
2) Using the for /f tokenizer itself to remove the line number from the findstr /n output lines.
(Using findstr /n is necessary to also get blank lines: They would be dropped if for /f read directly from the input file.)

But, as Jeb pointed out in a comment below, the above solution has one drawback the others don't: It drops colons at the beginning of lines.

So 2020-04-06 update just for fun, here's another 1-liner based on findstr.exe, that seems to work fine without the above drawbacks:

@echo off
setlocal DisableDelayedExpansion
for /f "tokens=* delims=0123456789" %%l in ('findstr /n "^" %1') do echo%%l

The additional tricks are:
3) Use digits 0-9 as delimiters, so that tokens=* skips the initial line number.
4) Use the colon, inserted by findstr /n after the line number, as the token separator after the echo command.

I'll leave it to Jeb to explain if there are corner cases where echo:something might fail :-)
All I can say is that this last version successfully restored line endings on my huge batch library, so exceptions, if any, must be quite rare!

With Git 2.15 (Q4 2017), "git branch" learned "-c/-C" to create a new branch by copying an existing one.

See commit c8b2cec (18 Jun 2017) by Ævar Arnfjörð Bjarmason (avar).
See commit 52d59cc, commit 5463caa (18 Jun 2017) by Sahil Dua (sahildua2305).
^{(Merged by Junio C Hamano -- gitster -- in commit 3b48045, 03 Oct 2017)}

branch: add a --copy (-c) option to go with --move (-m)

Add the ability to --copy a branch and its reflog and configuration, this uses the same underlying machinery as the --move (-m) option except the reflog and configuration is copied instead of being moved.

This is useful for e.g. copying a topic branch to a new version, e.g. work to work-2 after submitting the work topic to the list, while preserving all the tracking info and other configuration that goes with the branch, and unlike --move keeping the other already-submitted branch around for reference.

Note: when copying a branch, you remain on your current branch.
As Junio C Hamano explains, the initial implementation of this new feature was modifying HEAD, which was not good:

When creating a new branch B by copying the branch A that happens to be the current branch, it also updates HEAD to point at the new branch.
It probably was made this way because "git branch -c A B" piggybacked its implementation on "git branch -m A B",

This does not match the usual expectation.
If I were sitting on a blue chair, and somebody comes and repaints it to red, I would accept ending up sitting on a chair that is now red (I am also OK to stand, instead, as there no longer is my favourite blue chair).

But if somebody creates a new red chair, modelling it after the blue chair I am sitting on, I do not expect to be booted off of the blue chair and ending up on sitting on the new red one.

Generate a hash, maybe with a secret only you know, then store it in your DB so it can be associated with the user. Should work quite well.

for using git you have to be

root

if not then use sudo

for removing origin :

git remote remove origin

for adding origin :

git remote add origin http://giturl

Here is a sample implementation:

You added another \ to the end of C:\Temp\ in the SaveAs File line. Could be a problem. Do a test first before adding a path separator.

dateFormat = Format(itm.ReceivedTime, "yyyy-mm-dd H-mm")  
saveFolder = "C:\Temp"

You have not set objAtt so there is no need for "Set objAtt = Nothing". If there was it would be just before End Sub not in the loop.

Public Sub saveAttachtoDisk (itm As Outlook.MailItem) 
    Dim objAtt As Outlook.Attachment 
    Dim saveFolder As String Dim dateFormat
    dateFormat = Format(itm.ReceivedTime, "yyyy-mm-dd H-mm")  saveFolder = "C:\Temp"
    For Each objAtt In itm.Attachments
        objAtt.SaveAsFile saveFolder & "\" & dateFormat & objAtt.DisplayName
    Next
End Sub

Re: It worked the first day I started tinkering but after that it stopped saving files.

This is usually due to Security settings. It is a "trap" set for first time users to allow macros then take it away. http://www.slipstick.com/outlook-developer/how-to-use-outlooks-vba-editor/

new[,2] is a factor, not a numeric vector. Transform it first

new$MY_NEW_COLUMN <-as.numeric(as.character(new[,2])) * 5

You need to call the appendChild function to append your new element to an existing element in the DOM.

The isConnected method won't help, it will return true even if the remote side has closed the socket. Try this:

public class MyServer {
    public static final int PORT = 12345;
    public static void main(String[] args) throws IOException, InterruptedException {
        ServerSocket ss = ServerSocketFactory.getDefault().createServerSocket(PORT);
        Socket s = ss.accept();
        Thread.sleep(5000);
        ss.close();
        s.close();
    }
}

public class MyClient {
    public static void main(String[] args) throws IOException, InterruptedException {
        Socket s = SocketFactory.getDefault().createSocket("localhost", MyServer.PORT);
        System.out.println(" connected: " + s.isConnected());
        Thread.sleep(10000);
        System.out.println(" connected: " + s.isConnected());
    }
}

Start the server, start the client. You'll see that it prints "connected: true" twice, even though the socket is closed the second time.

The only way to really find out is by reading (you'll get -1 as return value) or writing (an IOException (broken pipe) will be thrown) on the associated Input/OutputStreams.

If this doesn't work it may be overridden by your current settings. You can right-click in the bar to the left of the code where line numbers would normally appear and turn them on with the context menu.

Bootstrap.yml is the first file loaded when you start spring boot application and application.property is loaded when application starts. So, you keep, may be your config server's credentials etc., in bootstrap.yml which is required during loading application and then in application.properties you keep may be database URL etc.

+1 for Consolas, together with a proper Color Scheme (I use the white one at the first screenshot)

\r move the cursor to the begin of the line.

Line breaks are managed differently on different systems. Some only use \n (line feed, e.g. Unix), some use (\r e.g. MacOS before OS X afaik) and some use \r\n (e.g. Windows afaik).

You can use round function just to suppress scientific notation for specific dataframe:

df1.round(4)

or you can suppress is globally by:

pd.options.display.float_format = '{:.4f}'.format

The sized box will not help in the case, the phone is in landscape mode.

At times it gives syntax error that "return is not a function" so in that case just remove return and it will work fine :) as shown below

OnClientClick="var b = validateView(); if(b) var b = ShowDiv1(); b;"

If you get the "Failed to find DDMS files..." do this:

1. Open eclipse
2. Open install new software
3. Click "Add..." -> type in (e.g.) "Android_over_HTTP" and in address put "http://dl-ssl.google.com/android/eclipse/".

Don't be alarmed that its not https, this helps to fetch stuff over http. This trick helped me to resolve the issue on MAC, I believe that this also should work on Windows / Linux

Hope this helps !

Unfortunately, there is still no multi-line commenting in R.

If your text editor supports column-mode, then use it to add a bunch of #s at once. If you use UltraEdit, Alt+c will put you in column mode.

You can create an empty vector like so

vec <- numeric(0)

And then add elements using c()

vec <- c(vec, 1:5)

However as romunov says, it's much better to pre-allocate a vector and then populate it (as this avoids reallocating a new copy of your vector every time you add elements)

Check https://github.com/mmin18/FlexLayout which you can use percent or java expression directly in layout xml.

<EditText
    app:layout_left="0%"
    app:layout_right="60%"
    app:layout_height="wrap_content"/>
<EditText
    app:layout_left="prev.right+10dp"
    app:layout_right="100%"
    app:layout_height="wrap_content"/>

jQuery.fn.doSomething = function() {
   //return something with 'this'
};

$('selector:empty').doSomething();

I guess its enough to return absolute path..

 Path.GetFileName( Request.Url.AbsolutePath )

using System.IO;

Try out cat and sprintf in your for loop.

eg.

cat(sprintf("\"%f\" \"%f\"\n", df$r, df$interest))

See here

Would be safer to do this.

@{ Response.Redirect("~/Account/LogIn?returnUrl=Products");}

So the controller for that action runs as well, to populate any model the view needs.

Source
Redirect from a view to another view

Although as @Satpal mentioned, I do recommend you do the redirecting on your controller.

*

master = Tk()
entryb1 = StringVar

Label(master, text="Input: ").grid(row=0, sticky=W)

Entry(master, textvariable=entryb1).grid(row=1, column=1)

b1 = Button(master, text="continue", command=print_content)
b1.grid(row=2, column=1)

def print_content():
    global entryb1
    content = entryb1.get()
    print(content)

master.mainloop()

What you did wrong was not put it inside a Define function then you hadn't used the .get function with the textvariable you had set.

Encountered the same issue with a slightly different code. In my case, I was using a "assets" folder subdivided into sub-folders for assets (sprites, audio, UI).

My code was simply at first in pubspec.yaml- alternative would be to detail every single file.

flutter:

  assets:
    - assets

Indentation and flutter clean was not enough to fix it. The files in the sub-folders were not loading by flutter. It seems like flutter needs to be "taken by the hand" and not looking at sub-folders without explicitly asking it to look at them. This worked for me:

flutter:

  assets:
    - assets/sprites/
    - assets/audio/
    - assets/UI/

So I had to detail each folder and each sub-folder that contains assets (mp3, jpg, etc). Doing so made the app work and saved me tons of time as the only solution detailed above would require me to manually list 30+ assets while the code here is just a few lines and easier to maintain.

STEP 1:

In Settings -> Basic -> Contact Email. (Give your/any email)

STEP 2: in 'App Review' Tab : change

Do you want to make this app and all its live features available to the general public? Yes

And cheers ..

There is no difference between moving and renaming; you should simply call Directory.Move.

In general, if you're only doing a single operation, you should use the static methods in the File and Directory classes instead of creating FileInfo and DirectoryInfo objects.

For more advice when working with files and directories, see here.

Try Jedi! There's a Vim plugin at https://github.com/davidhalter/jedi-vim.

It works just much better than anything else for Python in Vim. It even has support for renaming, goto, etc. The best part is probably that it really tries to understand your code (decorators, generators, etc. Just look at the feature list).

You simply cannot get PowerShell to ommit those pesky newlines. There is no script or cmdlet that does this.

Of course Write-Host is absolute nonsense because you can't redirect/pipe from it! You simply have to write your own:

using System;

namespace WriteToStdout
{
    class Program
    {
        static void Main(string[] args)
        {
            if (args != null)
            {
                Console.Write(string.Join(" ", args));
            }
        }
    }
}

E.g.

PS C:\> writetostdout finally I can write to stdout like echo -n
finally I can write to stdout like echo -nPS C:\>

The pseudo element :focus-within allows a parent to be selected if a descendent has focus.

An element can be focused if it has a tabindex attribute.

Browser support for focus-within

Tabindex

Example

.click {_x000D_
  cursor: pointer;_x000D_
}_x000D_
_x000D_
.color:focus-within .change {_x000D_
  color: red;_x000D_
}_x000D_
_x000D_
.color:focus-within p {_x000D_
  outline: 0;_x000D_
}

<div class="color">_x000D_
  <p class="change" tabindex="0">_x000D_
    I will change color_x000D_
  </p>_x000D_
  <p class="click" tabindex="1">_x000D_
    Click me_x000D_
  </p>_x000D_
</div>

You defined your method as non-static and you are trying to invoke it as static. That said...

1.if you want to invoke a static method, you should use the :: and define your method as static.

// Defining a static method in a Foo class.
public static function getAll() { /* code */ }

// Invoking that static method
Foo::getAll();

2.otherwise, if you want to invoke an instance method you should instance your class, use ->.

// Defining a non-static method in a Foo class.
public function getAll() { /* code */ }

// Invoking that non-static method.
$foo = new Foo();
$foo->getAll();

Note: In Laravel, almost all Eloquent methods return an instance of your model, allowing you to chain methods as shown below:

$foos = Foo::all()->take(10)->get();

In that code we are statically calling the all method via Facade. After that, all other methods are being called as instance methods.

This is made from the other solutions above.

$(document).ready(function(){  

    $("button").click(function(event){
        $(".area").toggle();
        event.stopPropagation();    //stops the click event to go "throu" the button an hit the document
    });
    
    
    $(document).click(function() {
        $(".area").hide();
    });
    
    
    $(".interface").click(function(event) {
        event.stopPropagation();
        return false;                                        
    });
});

<div>
    <div>
        <button> Press here for content</button> 
      <div class="area">
        <div class="interface"> Content</div>
      </div>
    </div>       
</div>

You can use DateTimeImmutable::modify() :

$date = DateTimeImmutable::createFromFormat('Y-m-d', '2021-02-13');

var_dump($date->modify('first day of this month')->format('Y-m-d')); // string(10) "2021-02-01"
var_dump($date->modify('last day of this month')->format('Y-m-d')); // string(10) "2021-02-28"

You have to first obtain the Range object. Also, getCell() will not return the value of the cell but instead will return a Range object of the cell. So, use something on the lines of

function email() {

// Opens SS by its ID

var ss = SpreadsheetApp.openById("0AgJjDgtUl5KddE5rR01NSFcxYTRnUHBCQ0stTXNMenc");

// Get the name of this SS

var name = ss.getName();  // Not necessary 

// Read cell 1,1 * Line below does't work *

// var data = Range.getCell(0, 0);
var sheet = ss.getSheetByName('Sheet1'); // or whatever is the name of the sheet 
var range = sheet.getRange(1,1); 
var data = range.getValue();

}

The hierarchy is Spreadsheet --> Sheet --> Range --> Cell.

return can increase code readability:

foo <- function() {
    if (a) return(a)       
    b     
}

Using an empty string is perfectly fine and actually much safer than simply using $_SERVER['PHP_SELF'].

When using $_SERVER['PHP_SELF'] it is very easy to inject malicious data by simply appending /<script>... after the whatever.php part of the URL so you should not use this method and stop using any PHP tutorial that suggests it.

Compare them as other values:

if($array_a == $array_b) {
  //they are the same
}

You can read about all array operators here: http://php.net/manual/en/language.operators.array.php Note for example that === also checks that the types and order of the elements in the arrays are the same.

First implement Parcelable in your class. Then pass object like this.

SendActivity.java

ObjectA obj = new ObjectA();

// Set values etc.

Intent i = new Intent(this, MyActivity.class);
i.putExtra("com.package.ObjectA", obj);

startActivity(i);

ReceiveActivity.java

Bundle b = getIntent().getExtras();
ObjectA obj = b.getParcelable("com.package.ObjectA");

The package string isn't necessary, just the string needs to be the same in both Activities

REFERENCE

The default value of any Object, such as Boolean, is null.

The default value for a boolean is false.

Note: Every primitive has a wrapper class. Every wrapper uses a reference which has a default of null. Primitives have different default values:

boolean -> false

byte, char, short, int, long -> 0

float, double -> 0.0

Note (2): void has a wrapper Void which also has a default of null and is it's only possible value (without using hacks).

Those pros and cons are provided by Stephan.

For Manual Deployment

• Pros
• Cons
  • Dependencies are out of the final jar.

Copy Dependencies to a specific directory

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-dependency-plugin</artifactId>
  <executions>
    <execution>
      <id>copy-dependencies</id>
      <phase>prepare-package</phase>
      <goals>
        <goal>copy-dependencies</goal>
      </goals>
      <configuration>
        <outputDirectory>${project.build.directory}/${project.build.finalName}.lib</outputDirectory>
      </configuration>
    </execution>
  </executions>
</plugin>

Make the Jar Executable and Classpath Aware

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-jar-plugin</artifactId>
  <configuration>
    <archive>
      <manifest>
        <addClasspath>true</addClasspath>
        <classpathPrefix>${project.build.finalName}.lib/</classpathPrefix>
        <mainClass>${fully.qualified.main.class}</mainClass>
      </manifest>
    </archive>
  </configuration>
</plugin>

At this point the jar is actually executable with external classpath elements.

$ java -jar target/${project.build.finalName}.jar

Make Deployable Archives

The jar file is only executable with the sibling ...lib/ directory. We need to make archives to deploy with the directory and its content.

<plugin>
  <groupId>org.apache.maven.plugins</groupId>
  <artifactId>maven-antrun-plugin</artifactId>
  <executions>
    <execution>
      <id>antrun-archive</id>
      <phase>package</phase>
      <goals>
        <goal>run</goal>
      </goals>
      <configuration>
        <target>
          <property name="final.name" value="${project.build.directory}/${project.build.finalName}"/>
          <property name="archive.includes" value="${project.build.finalName}.${project.packaging} ${project.build.finalName}.lib/*"/>
          <property name="tar.destfile" value="${final.name}.tar"/>
          <zip basedir="${project.build.directory}" destfile="${final.name}.zip" includes="${archive.includes}" />
          <tar basedir="${project.build.directory}" destfile="${tar.destfile}" includes="${archive.includes}" />
          <gzip src="${tar.destfile}" destfile="${tar.destfile}.gz" />
          <bzip2 src="${tar.destfile}" destfile="${tar.destfile}.bz2" />
        </target>
      </configuration>
    </execution>
  </executions>
</plugin>

Now you have target/${project.build.finalName}.(zip|tar|tar.bz2|tar.gz) which each contains the jar and lib/*.

Apache Maven Assembly Plugin

• Pros
• Cons
  • No class relocation support (use maven-shade-plugin if class relocation is needed).

        </descriptorRefs>
      </configuration>
    </execution>
  </executions>
</plugin>

You have target/${project.bulid.finalName}-jar-with-dependencies.jar.

Apache Maven Shade Plugin

          </transformer>
        </transformers>
      </configuration>
    </execution>
  </executions>
</plugin>

You have target/${project.build.finalName}-shaded.jar.

onejar-maven-plugin

Spring Boot Maven Plugin

• Pros
• Cons
  • Add potential unecessary Spring and Spring Boot related classes.

You have target/${project.bulid.finalName}-spring-boot.jar.

Ok, so we know that were in a frame. So we location.href to another special page with the path as a GET variable. We now explain to the user what is going on and provide a link with a target="_TOP" option. It's simple and would probably work (haven't tested it), but it requires some user interaction. Maybe you could point out the offending site to the user and make a hall of shame of click jackers to your site somewhere.. Just an idea, but it night work..

You can use this function, if you want to remove the element (without index)

removeItem(item) {
  this.setState(prevState => {
    data: prevState.data.filter(i => i !== item)
  });
}

Objective-C is a more perfect superset of C. In C and Objective-C implicit casting from void* to a struct pointer is allowed.

Foo* bar = malloc(sizeof(Foo));

C++ will not compile unless the void pointer is explicitly cast:

Foo* bar = (Foo*)malloc(sizeof(Foo));

The relevance of this to every day programming is zero, just a fun trivia fact.

I don't know if it has an official name, but I call it the Right-Left Thingy(TM).

Start at the variable, then go right, and left, and right...and so on.

int* arr1[8];

arr1 is an array of 8 pointers to integers.

int (*arr2)[8];

arr2 is a pointer (the parenthesis block the right-left) to an array of 8 integers.

int *(arr3[8]);

arr3 is an array of 8 pointers to integers.

This should help you out with complex declarations.

UPDATE: The code below has a bug, described here. The test program below works, but if you were to use DayOfWeek.Mon (for example) before DayOfWeek itself, it would fail because DayOfWeek has not been initialized (use of an inner object does not cause an outer object to be initialized). You can still use this code if you do something like val enums = Seq( DayOfWeek ) in your main class, forcing initialization of your enums, or you can use chaotic3quilibrium's modifications. Looking forward to a macro-based enum!

If you want

• warnings about non-exhaustive pattern matches
• an Int ID assigned to each enum value, which you can optionally control
• an immutable List of the enum values, in the order they were defined
• an immutable Map from name to enum value
• an immutable Map from id to enum value
• places to stick methods/data for all or particular enum values, or for the enum as a whole
• ordered enum values (so you can test, for example, whether day < Wednesday)
• the ability to extend one enum to create others

then the following may be of interest. Feedback welcome.

In this implementation there are abstract Enum and EnumVal base classes, which you extend. We'll see those classes in a minute, but first, here's how you would define an enum:

object DayOfWeek extends Enum {
  sealed abstract class Val extends EnumVal
  case object Mon extends Val; Mon()
  case object Tue extends Val; Tue()
  case object Wed extends Val; Wed()
  case object Thu extends Val; Thu()
  case object Fri extends Val; Fri()
  case object Sat extends Val; Sat()
  case object Sun extends Val; Sun()
}

Note that you have to use each enum value (call its apply method) to bring it to life. [I wish inner objects weren't lazy unless I specifically ask for them to be. I think.]

We could of course add methods/data to DayOfWeek, Val, or the individual case objects if we so desired.

And here's how you would use such an enum:

object DayOfWeekTest extends App {

  // To get a map from Int id to enum:
  println( DayOfWeek.valuesById )

  // To get a map from String name to enum:
  println( DayOfWeek.valuesByName )

  // To iterate through a list of the enum values in definition order,
  // which can be made different from ID order, and get their IDs and names:
  DayOfWeek.values foreach { v => println( v.id + " = " + v ) }

  // To sort by ID or name:
  println( DayOfWeek.values.sorted mkString ", " )
  println( DayOfWeek.values.sortBy(_.toString) mkString ", " )

  // To look up enum values by name:
  println( DayOfWeek("Tue") ) // Some[DayOfWeek.Val]
  println( DayOfWeek("Xyz") ) // None

  // To look up enum values by id:
  println( DayOfWeek(3) )         // Some[DayOfWeek.Val]
  println( DayOfWeek(9) )         // None

  import DayOfWeek._

  // To compare enums as ordinals:
  println( Tue < Fri )

  // Warnings about non-exhaustive pattern matches:
  def aufDeutsch( day: DayOfWeek.Val ) = day match {
    case Mon => "Montag"
    case Tue => "Dienstag"
    case Wed => "Mittwoch"
    case Thu => "Donnerstag"
    case Fri => "Freitag"
 // Commenting these out causes compiler warning: "match is not exhaustive!"
 // case Sat => "Samstag"
 // case Sun => "Sonntag"
  }

}

Here's what you get when you compile it:

DayOfWeekTest.scala:31: warning: match is not exhaustive!
missing combination            Sat
missing combination            Sun

  def aufDeutsch( day: DayOfWeek.Val ) = day match {
                                         ^
one warning found

You can replace "day match" with "( day: @unchecked ) match" where you don't want such warnings, or simply include a catch-all case at the end.

When you run the above program, you get this output:

Map(0 -> Mon, 5 -> Sat, 1 -> Tue, 6 -> Sun, 2 -> Wed, 3 -> Thu, 4 -> Fri)
Map(Thu -> Thu, Sat -> Sat, Tue -> Tue, Sun -> Sun, Mon -> Mon, Wed -> Wed, Fri -> Fri)
0 = Mon
1 = Tue
2 = Wed
3 = Thu
4 = Fri
5 = Sat
6 = Sun
Mon, Tue, Wed, Thu, Fri, Sat, Sun
Fri, Mon, Sat, Sun, Thu, Tue, Wed
Some(Tue)
None
Some(Thu)
None
true

Note that since the List and Maps are immutable, you can easily remove elements to create subsets, without breaking the enum itself.

Here is the Enum class itself (and EnumVal within it):

abstract class Enum {

  type Val <: EnumVal

  protected var nextId: Int = 0

  private var values_       =       List[Val]()
  private var valuesById_   = Map[Int   ,Val]()
  private var valuesByName_ = Map[String,Val]()

  def values       = values_
  def valuesById   = valuesById_
  def valuesByName = valuesByName_

  def apply( id  : Int    ) = valuesById  .get(id  )  // Some|None
  def apply( name: String ) = valuesByName.get(name)  // Some|None

  // Base class for enum values; it registers the value with the Enum.
  protected abstract class EnumVal extends Ordered[Val] {
    val theVal = this.asInstanceOf[Val]  // only extend EnumVal to Val
    val id = nextId
    def bumpId { nextId += 1 }
    def compare( that:Val ) = this.id - that.id
    def apply() {
      if ( valuesById_.get(id) != None )
        throw new Exception( "cannot init " + this + " enum value twice" )
      bumpId
      values_ ++= List(theVal)
      valuesById_   += ( id       -> theVal )
      valuesByName_ += ( toString -> theVal )
    }
  }

}

And here is a more advanced use of it which controls the IDs and adds data/methods to the Val abstraction and to the enum itself:

object DayOfWeek extends Enum {

  sealed abstract class Val( val isWeekday:Boolean = true ) extends EnumVal {
    def isWeekend = !isWeekday
    val abbrev = toString take 3
  }
  case object    Monday extends Val;    Monday()
  case object   Tuesday extends Val;   Tuesday()
  case object Wednesday extends Val; Wednesday()
  case object  Thursday extends Val;  Thursday()
  case object    Friday extends Val;    Friday()
  nextId = -2
  case object  Saturday extends Val(false); Saturday()
  case object    Sunday extends Val(false);   Sunday()

  val (weekDays,weekendDays) = values partition (_.isWeekday)
}

A lot of things can configured in applicationproperties. Unfortunately this feature only in Version 1.3, but you can add in a Config-Class

@Autowired(required = true)
public void configureJackson(ObjectMapper jackson2ObjectMapper) {
    jackson2ObjectMapper.setSerializationInclusion(JsonInclude.Include.NON_NULL);
}

[UPDATE: You must work on the ObjectMapper because the build()-method is called before the config is runs.]

Hope this helps for item #2: a) You can sort by total bill then reset the index to this column b) Use palette="Blue" to use this color to scale your chart from light blue to dark blue (if dark blue to light blue then use palette="Blues_d")

import pandas as pd
import seaborn as sns
%matplotlib inline

df=pd.read_csv("https://raw.githubusercontent.com/wesm/pydata-book/master/ch08/tips.csv", sep=',')
groupedvalues=df.groupby('day').sum().reset_index()
groupedvalues=groupedvalues.sort_values('total_bill').reset_index()
g=sns.barplot(x='day',y='tip',data=groupedvalues, palette="Blues")

or can do this...
set all btn ( class name like : .btn- + $theme-colors: map-merge ) styles at one time :

@each $color, $value in $theme-colors {
  .btn-#{$color} {
    @include button-variant($value, $value,
    // modify
    $hover-background: lighten($value, 7.5%),
    $hover-border: lighten($value, 10%),
    $active-background: lighten($value, 10%),
    $active-border: lighten($value, 12.5%)
    // /modify
    );
  }
}

// code from "node_modules/bootstrap/scss/_buttons.scss"

should add into your customization scss file.

<script type="text/javascript">
    document.write(document.referrer);
</script>

document.referrer serves your purpose, but it doesn't work for Internet Explorer versions earlier than IE9.

It will work for other popular browsers, like Chrome, Mozilla, Opera, Safari etc.

I've tryied all answers of this topic, but just this below worked fine on my project.

Angular 7 and AGM Core 1.0.0-beta.7

<agm-map [latitude]="lat" [longitude]="long" [zoom]="zoom" [fitBounds]="true">
  <agm-marker latitude="{{localizacao.latitude}}" longitude="{{localizacao.longitude}}" [agmFitBounds]="true"
    *ngFor="let localizacao of localizacoesTec">
  </agm-marker>
</agm-map>

The properties [agmFitBounds]="true" at agm-marker and [fitBounds]="true" at agm-map does the job

In Angular 7, the (ngModelChange)="eventHandler()" will fire before the value bound to [(ngModel)]="value" is changed while the (change)="eventHandler()" will fire after the value bound to [(ngModel)]="value" is changed.

By default, Windows makes the root of each drive available (provided you've got Administrator privileges) as (e.g.) \\server\c$. These are known as Administrative Shares.

I was getting the same error while the jar was present. No solution worked. What worked was deleting the jar from the file system (from .m2 directory) and then cleaning the maven project.

So, your input is 'dan|warrior|54' and you want "warrior". You do this like so:

>>> dan = 'dan|warrior|54'
>>> dan.split('|')[1]
"warrior"

try this!!!

using following code you could compare one or many fields to generate a result list as per your need. result list will contain only modified item(s).

// veriables been used
List<T> diffList = new List<T>();
List<T> gotResultList = new List<T>();



// compare First field within my MyList
gotResultList = MyList1.Where(a => !MyList2.Any(a1 => a1.MyListTField1 == a.MyListTField1)).ToList().Except(gotResultList.Where(a => !MyList2.Any(a1 => a1.MyListTField1 == a.MyListTField1))).ToList();
// Generate result list
diffList.AddRange(gotResultList);

// compare Second field within my MyList
gotResultList = MyList1.Where(a => !MyList2.Any(a1 => a1.MyListTField2 == a.MyListTField2)).ToList().Except(gotResultList.Where(a => !MyList2.Any(a1 => a1.MyListTField2 == a.MyListTField2))).ToList();
// Generate result list
diffList.AddRange(gotResultList);


MessageBox.Show(diffList.Count.ToString);

This works for me, and in this case was a remote connection: Note: The port was IMPORTANT for me

$dsn = "sqlsrv:Server=server.dyndns.biz,1433;Database=DBNAME";
$conn = new PDO($dsn, "root", "P4sw0rd");
$conn->setAttribute( PDO::ATTR_ERRMODE, PDO::ERRMODE_EXCEPTION );

$sql = "SELECT * FROM Table";

foreach ($conn->query($sql) as $row) {
    print_r($row);
} 

This is what worked for me:

    KeyStore keyStore  = KeyStore.getInstance("PKCS12");
    FileInputStream instream = new FileInputStream(new File("client-p12-keystore.p12"));
    try {
        keyStore.load(instream, "password".toCharArray());
    } finally {
        instream.close();
    }

    // Trust own CA and all self-signed certs
    SSLContext sslcontext = SSLContexts.custom()
        .loadKeyMaterial(keyStore, "password".toCharArray())
        //.loadTrustMaterial(trustStore, new TrustSelfSignedStrategy())
        .build();
    // Allow TLSv1 protocol only
    SSLConnectionSocketFactory sslsf = new SSLConnectionSocketFactory(
        sslcontext,
        new String[] { "TLSv1" },
        null,
        SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER); //TODO
    CloseableHttpClient httpclient = HttpClients.custom()
        .setHostnameVerifier(SSLConnectionSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER) //TODO
        .setSSLSocketFactory(sslsf)
        .build();
    try {

        HttpGet httpget = new HttpGet("https://localhost:8443/secure/index");

        System.out.println("executing request" + httpget.getRequestLine());

        CloseableHttpResponse response = httpclient.execute(httpget);
        try {
            HttpEntity entity = response.getEntity();

            System.out.println("----------------------------------------");
            System.out.println(response.getStatusLine());
            if (entity != null) {
                System.out.println("Response content length: " + entity.getContentLength());
            }
            EntityUtils.consume(entity);
        } finally {
            response.close();
        }
    } finally {
        httpclient.close();
    }
}

As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).

On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.

1. Bootstrap = responsive page
2. AngularJS = MVC
3. Material Design = great UI/UX

You can check awesome material design components for AngularJS:

I found this question through another question which was KeystoneJS specific but was marked as duplicate. If anyone here might be looking for a Keystone answer, this is how I did my deep populate query in Keystone.

Mongoose two level population using KeystoneJs [duplicate]

exports.getStoreWithId = function (req, res) {
    Store.model
        .find()
        .populate({
            path: 'productTags productCategories',
            populate: {
                path: 'tags',
            },
        })
        .where('updateId', req.params.id)
        .exec(function (err, item) {
            if (err) return res.apiError('database error', err);
            // possibly more than one
            res.apiResponse({
                store: item,
            });
        });
};

function getValue(obj)
{  
   // it will return the selected text
   // obj variable will contain the object of check box
   var text = obj.options[obj.selectedIndex].innerHTML ; 

}

I would change zoom for transform in all cases because, as explained by other answers, they are not equivalent. In my case it was also necessary to apply transform-origin property to place the items where I wanted.

This worked for me in Chome, Safari and Firefox:

transform: scale(0.4);
transform-origin: top left;
-moz-transform: scale(0.4);
-moz-transform-origin: top left;
