Claiming that the C++ compiler can produce more optimal code than a competent assembly language programmer is a very bad mistake. And especially in this case. The human always can make the code better than the compiler can, and this particular situation is a good illustration of this claim.

The timing difference you're seeing is because the assembly code in the question is very far from optimal in the inner loops.

(The below code is 32-bit, but can be easily converted to 64-bit)

For example, the sequence function can be optimized to only 5 instructions:

    .seq:
        inc     esi                 ; counter
        lea     edx, [3*eax+1]      ; edx = 3*n+1
        shr     eax, 1              ; eax = n/2
        cmovc   eax, edx            ; if CF eax = edx
        jnz     .seq                ; jmp if n<>1

The whole code looks like:

include "%lib%/freshlib.inc"
@BinaryType console, compact
options.DebugMode = 1
include "%lib%/freshlib.asm"

start:
        InitializeAll
        mov ecx, 999999
        xor edi, edi        ; max
        xor ebx, ebx        ; max i

    .main_loop:

        xor     esi, esi
        mov     eax, ecx

    .seq:
        inc     esi                 ; counter
        lea     edx, [3*eax+1]      ; edx = 3*n+1
        shr     eax, 1              ; eax = n/2
        cmovc   eax, edx            ; if CF eax = edx
        jnz     .seq                ; jmp if n<>1

        cmp     edi, esi
        cmovb   edi, esi
        cmovb   ebx, ecx

        dec     ecx
        jnz     .main_loop

        OutputValue "Max sequence: ", edi, 10, -1
        OutputValue "Max index: ", ebx, 10, -1

        FinalizeAll
        stdcall TerminateAll, 0

In order to compile this code, FreshLib is needed.

In my tests, (1 GHz AMD A4-1200 processor), the above code is approximately four times faster than the C++ code from the question (when compiled with -O0: 430 ms vs. 1900 ms), and more than two times faster (430 ms vs. 830 ms) when the C++ code is compiled with -O3.

The output of both programs is the same: max sequence = 525 on i = 837799.

I followed my frnd suggestion and it worked like a gem for me:

Working Code:

1) Downloaded chromedriver.

2) Code is

import org.openqa.selenium.WebDriver;

import org.openqa.selenium.chrome.ChromeDriver;

public class Sel {
  public static void main(String[] args) {
    // TODO Auto-generated method stub
    System.setProperty("webdriver.chrome.driver", "C:\\Users\\Downloads\\chromedriver_win32\\chromedriver.exe"); // path of chromedriver 
    WebDriver driver = new ChromeDriver();

      driver.get("https://google.ca");
      driver.manage().window().maximize();
      driver.getTitle();

  }
}

<?php
$curl = curl_init();

curl_setopt_array($curl, array(
CURLOPT_URL => "your api goes here",
CURLOPT_RETURNTRANSFER => true,

  ),
 ));

$response = curl_exec($curl);
$data = json_decode($response, true);

echo $data;

?>

I wanted a solution that did not create any extra objects (ie listeners) that would have to be garbage collected later, and did not require nesting a view holder inside an adapter class.

In the ViewHolder class

private static class MyViewHolder extends RecyclerView.ViewHolder implements View.OnClickListener {

        private final TextView ....// declare the fields in your view
        private ClickHandler ClickHandler;

        public MyHolder(final View itemView) {
            super(itemView);
            nameField = (TextView) itemView.findViewById(R.id.name);
            //find other fields here...
            Button myButton = (Button) itemView.findViewById(R.id.my_button);
            myButton.setOnClickListener(this);
        }
        ...
        @Override
        public void onClick(final View view) {
            if (clickHandler != null) {
                clickHandler.onMyButtonClicked(getAdapterPosition());
            }
        }

Points to note: the ClickHandler interface is defined, but not initialized here, so there is no assumption in the onClick method that it was ever initialized.

The ClickHandler interface looks like this:

private interface ClickHandler {
    void onMyButtonClicked(final int position);
} 

In the adapter, set an instance of 'ClickHandler' in the constructor, and override onBindViewHolder, to initialize `clickHandler' on the view holder:

private class MyAdapter extends ...{

    private final ClickHandler clickHandler;

    public MyAdapter(final ClickHandler clickHandler) {
        super(...);
        this.clickHandler = clickHandler;
    }

    @Override
    public void onBindViewHolder(final MyViewHolder viewHolder, final int position) {
        super.onBindViewHolder(viewHolder, position);
        viewHolder.clickHandler = this.clickHandler;
    }

Note: I know that viewHolder.clickHandler is potentially getting set multiple times with the exact same value, but this is cheaper than checking for null and branching, and there is no memory cost, just an extra instruction.

Finally, when you create the adapter, you are forced to pass a ClickHandlerinstance to the constructor, as so:

adapter = new MyAdapter(new ClickHandler() {
    @Override
    public void onMyButtonClicked(final int position) {
        final MyModel model = adapter.getItem(position);
        //do something with the model where the button was clicked
    }
});

Note that adapter is a member variable here, not a local variable

I was struggling with this, my app was installing but not complete (almost 60% I can say) in iOS8, but in iOS7.1 it was working as expected. The error message popped was:

"Cannot install at this time". 

Finally Zillan's link helped me to get apple documentation. So, check:

1. make sure the internet reachability in your device as you will be in local network/ intranet.
2. Also make sure the address ax.init.itunes.apple.com is not getting blocked by your firewall/proxy (Just type this address in safari, a blank page must load).

As soon as I changed the proxy it installed completely. Hope it will help someone.

This way I solved my problem. Hope it helps others. In my case I created a class, a field, their getter & setter and then provide the object instead of string.

Use this

public static class EncryptedData {
    private String encryptedData;

    public String getEncryptedData() {
        return encryptedData;
    }

    public void setEncryptedData(String encryptedData) {
        this.encryptedData = encryptedData;
    }
}

@PutMapping(value = MY_IP_ADDRESS)
public ResponseEntity<RestResponse> updateMyIpAddress(@RequestBody final EncryptedData encryptedData) {
    try {
        Path path = Paths.get(PUBLIC_KEY);
        byte[] bytes = Files.readAllBytes(path);
        PKCS8EncodedKeySpec ks = new PKCS8EncodedKeySpec(base64.decode(bytes));
        PrivateKey privateKey = KeyFactory.getInstance(CRYPTO_ALGO_RSA).generatePrivate(ks);

        Cipher cipher = Cipher.getInstance(CRYPTO_ALGO_RSA);
        cipher.init(Cipher.PRIVATE_KEY, privateKey);
        String decryptedData = new String(cipher.doFinal(encryptedData.getEncryptedData().getBytes()));
        String[] dataArray = decryptedData.split("|");


        Method updateIp = Class.forName("com.cuanet.client.helper").getMethod("methodName", String.class,String.class);
        updateIp.invoke(null, dataArray[0], dataArray[1]);

    } catch (Exception e) {
        LOG.error("Unable to update ip address for encrypted data: "+encryptedData, e);
    }

    return null;

Instead of this

@PutMapping(value = MY_IP_ADDRESS)
public ResponseEntity<RestResponse> updateMyIpAddress(@RequestBody final EncryptedData encryptedData) {
    try {
        Path path = Paths.get(PUBLIC_KEY);
        byte[] bytes = Files.readAllBytes(path);
        PKCS8EncodedKeySpec ks = new PKCS8EncodedKeySpec(base64.decode(bytes));
        PrivateKey privateKey = KeyFactory.getInstance(CRYPTO_ALGO_RSA).generatePrivate(ks);

        Cipher cipher = Cipher.getInstance(CRYPTO_ALGO_RSA);
        cipher.init(Cipher.PRIVATE_KEY, privateKey);
        String decryptedData = new String(cipher.doFinal(encryptedData.getBytes()));
        String[] dataArray = decryptedData.split("|");


        Method updateIp = Class.forName("com.cuanet.client.helper").getMethod("methodName", String.class,String.class);
        updateIp.invoke(null, dataArray[0], dataArray[1]);

    } catch (Exception e) {
        LOG.error("Unable to update ip address for encrypted data: "+encryptedData, e);
    }

    return null;
}

The problem is not in your code but in your json:

{"Compemployes":[{"id":1001,"name":"jhon"}, {"id":1002,"name":"jhon"}]}

this represents an object which contains a property Compemployes which is a list of Employee. In that case you should create that object like:

class EmployeList{
    private List<Employe> compemployes;
    (with getter an setter)
}

and to deserialize the json simply do:

EmployeList employeList = mapper.readValue(jsonString,EmployeList.class);

If your json should directly represent a list of employees it should look like:

[{"id":1001,"name":"jhon"}, {"id":1002,"name":"jhon"}]

Last remark:

List<Employee> list2 = mapper.readValue(jsonString, 
TypeFactory.collectionType(List.class, Employee.class));

TypeFactory.collectionType is deprecated you should now use something like:

List<Employee> list = mapper.readValue(jsonString,
TypeFactory.defaultInstance().constructCollectionType(List.class,  
   Employee.class));

If you have a remote configured and you have / don't care about losing some unpushed code, you can do :

git fetch && git reset --hard

virtualenv is a tool to create isolated Python environments.

you will need to add the following to fix command python setup.py egg_info failed with error code 1, so inside your requirements.txt add this:

virtualenv==12.0.7

You should just grab the window by the title bar and snap it to the left side of your screen (close browser) then reopen the browser ans snap it to the top... problem is over.

Maybe it is too late, but I am answering for future searches. TO perform spelling mistake correction, you first need to make sure the word is not absurd or from slang like, caaaar, amazzzing etc. with repeated alphabets. So, we first need to get rid of these alphabets. As we know in English language words usually have a maximum of 2 repeated alphabets, e.g., hello., so we remove the extra repetitions from the words first and then check them for spelling. For removing the extra alphabets, you can use Regular Expression module in Python.

Once this is done use Pyspellchecker library from Python for correcting spellings.

For implementation visit this link: https://rustyonrampage.github.io/text-mining/2017/11/28/spelling-correction-with-python-and-nltk.html

You could also use:

var latLon = L.latLng(40.737, -73.923);
var bounds = latLon.toBounds(500); // 500 = metres
map.panTo(latLon).fitBounds(bounds);

This will set the view level to fit the bounds in the map leaflet.

Just a little addition to the answer of @dAm2k :

In addition to sudo apt-get remove --purge mysql\*

I've done a sudo apt-get remove --purge mariadb\*.

I seems that in the new release of debian (stretch), when you install mysql it install mariadb package with it.

Hope it helps.

@Borealid's answer is correct, but suppose that you don't care about preserving the exact merging history of a branch and just want to cherry-pick a linearized version of it. Here's an easy and safe way to do that:

Starting state: you are on branch X, and you want to cherry-pick the commits Y..Z.

1. git checkout -b tempZ Z
2. git rebase Y
3. git checkout -b newX X
4. git cherry-pick Y..tempZ
5. (optional) git branch -D tempZ

What this does is to create a branch tempZ based on Z, but with the history from Y onward linearized, and then cherry-pick that onto a copy of X called newX. (It's safer to do this on a new branch rather than to mutate X.) Of course there might be conflicts in step 4, which you'll have to resolve in the usual way (cherry-pick works very much like rebase in that respect). Finally it deletes the temporary tempZ branch.

If step 2 gives the message "Current branch tempZ is up to date", then Y..Z was already linear, so just ignore that message and proceed with steps 3 onward.

Then review newX and see whether that did what you wanted.

(Note: this is not the same as a simple git rebase X when on branch Z, because it doesn't depend in any way on the relationship between X and Y; there may be commits between the common ancestor and Y that you didn't want.)

The official answer from Facebook (http://developers.facebook.com/bugs/282710765082535):

Mikhail,

The facebook android sdk no longer supports android 1.5 and 1.6. Please upgrade to the next api version.

Good luck with your implementation.

On Windows OS by default git is instaled with

core.ignorecase = true

This means that git repo files will be case insensitive, to change this you need to execute:

\yourLocalRepo> git config core.ignorecase false

you can find this configuration on .git\config file

It's an inlined image (png), encoded in base64. It can make a page faster: the browser doesn't have to query the server for the image data separately, saving a round trip.

(It can also make it slower if abused: these resources are not cached, so the bytes are included in each page load.)

After decoding, it looks like the data is a repeating structure that's 8 bytes long, or some multiple thereof. It's just binary data though; what it might mean, I have no idea. There are 2064 entries, which means that it could be a list of 2064 8-byte items down to 129 128-byte items.

My guess is that you are trying to restore in lower versions which wont work

I just had the same problem and ended up doing:

git rebase -i HEAD~N

(N is the number of commits git will show you)

That prompts your text editor and then you can remove the commit you want by deleting the line associated with it.

All you need is a reluctant quantifier:

regex: /aa.*?aa/

aabbabcaabda   => aabbabcaa

aaaaaabda      => aaaa

aabbabcaabda   => aabbabcaa

aababaaaabdaa  => aababaa, aabdaa

You could use negative lookahead, too, but in this case it's just a more verbose way accomplish the same thing. Also, it's a little trickier than gpojd made it out to be. The lookahead has to be applied at each position before the dot is allowed to consume the next character.

/aa(?:(?!aa).)*aa/

As for the approach suggested by Claudiu and finnw, it'll work okay when the sentinel string is only two characters long, but (as Claudiu acknowledged) it's too unwieldy for longer strings.

Alternative escaping syntax:

LIKE Wildcard Literals

The JDBC driver supports the {escape 'escape character'} syntax for using LIKE clause wildcards as literals.

SELECT *
FROM tab
WHERE col LIKE 'a\_c' {escape '\'};

You have to do some encoding before using fit. As it was told fit() does not accept Strings but you solve this.

There are several classes that can be used :

• LabelEncoder : turn your string into incremental value
• OneHotEncoder : use One-of-K algorithm to transform your String into integer

Personally I have post almost the same question on StackOverflow some time ago. I wanted to have a scalable solution but didn't get any answer. I selected OneHotEncoder that binarize all the strings. It is quite effective but if you have a lot different strings the matrix will grow very quickly and memory will be required.

which means that cacerts keystore isn't password protected

That's a false assumption. If you read more carefully, you'll find that the listing was provided without verifying the integrity of the keystore because you didn't provide the password. The listing doesn't require a password, but your keystore definitely has a password, as indicated by:

In order to verify its integrity, you must provide your keystore password.

Java's default cacerts password is "changeit", unless you're on a Mac, where it's "changeme" up to a certain point. Apparently as of Mountain Lion (based on comments and another answer here), the password for Mac is now also "changeit", probably because Oracle is now handling distribution for the Mac JVM as well.

You mean like length or size()?

Stopwatch is designed for this purpose and is one of the best way to measure execution time in .NET.

var watch = System.Diagnostics.Stopwatch.StartNew();
/* the code that you want to measure comes here */
watch.Stop();
var elapsedMs = watch.ElapsedMilliseconds;

Do not use DateTimes to measure execution time in .NET.

You can give it a try.. Added a working example. When focus is on input, turning on caps lock makes the led go red otherwise green. (Haven't tested on mac/linux)

NOTE: Both versions are working for me. Thanks for constructive inputs in the comments.

OLD VERSION: https://jsbin.com/mahenes/edit?js,output

Also, here is a modified version (can someone test on mac and confirm)

NEW VERSION: https://jsbin.com/xiconuv/edit?js,output

NEW VERSION:

function isCapslock(e) {
  const IS_MAC = /Mac/.test(navigator.platform);

  const charCode = e.charCode;
  const shiftKey = e.shiftKey;

  if (charCode >= 97 && charCode <= 122) {
    capsLock = shiftKey;
  } else if (charCode >= 65 && charCode <= 90
    && !(shiftKey && IS_MAC)) {
    capsLock = !shiftKey;
  }

  return capsLock;
}

OLD VERSION:

function isCapslock(e) {
  e = (e) ? e : window.event;

  var charCode = false;
  if (e.which) {
    charCode = e.which;
  } else if (e.keyCode) {
    charCode = e.keyCode;
  }

  var shifton = false;
  if (e.shiftKey) {
    shifton = e.shiftKey;
  } else if (e.modifiers) {
    shifton = !!(e.modifiers & 4);
  }

  if (charCode >= 97 && charCode <= 122 && shifton) {
    return true;
  }

  if (charCode >= 65 && charCode <= 90 && !shifton) {
    return true;
  }

  return false;
}

For international characters, additional check can be added for the following keys as needed. You have to get the keycode range for characters you are interested in, may be by using a keymapping array which will hold all the valid use case keys you are addressing...

uppercase A-Z or 'Ä', 'Ö', 'Ü', lowercase a-Z or 0-9 or 'ä', 'ö', 'ü'

The above keys are just sample representation.

tar.gz file is just a tar file that's been gzipped. Both tar and gzip are available for windows.

If you like GUIs (Graphical user interface), 7zip can pack with both tar and gzip.

<?PHP
echo "Firstline";
include('classes/connection.php');
echo "I will run if include but not on Require";
?>

A very simple Practical example with code. The first echo will be displayed. No matter you use include or require because its runs before include or required.

To check the result, In second line of a code intentionally provide the wrong path to the file or make error in file name. Thus the second echo to be displayed or not will be totally dependent on whether you use require or include.

If you use require the second echo will not execute but if you use include not matter what error comes you will see the result of second echo too.

you can use this

body{ background-image: url('../img/bg.png'); }

I tried this on my project where I need to set the background image of a div so I used this and it worked!

I implemented the answer suggested by @user18490 but ran into two problems:

• First bouncing when user clicks on several tabs/links multiple times in short succession
• Second, the undefined error mentioned by @krivar

I developed the following class to get around the mentioned problems, and it works fine:

export class SScroll{
    constructor(){
        this.delay=501      //ms
        this.duration=500   //ms
        this.lastClick=0
    }

    lastClick
    delay
    duration

    scrollTo=(destID)=>{
        /* To prevent "bounce" */
        /* https://stackoverflow.com/a/28610565/3405291 */
        if(this.lastClick>=(Date.now()-this.delay)){return}
        this.lastClick=Date.now()

        const dest=document.getElementById(destID)
        const to=dest.offsetTop
        if(document.body.scrollTop==to){return}
        const diff=to-document.body.scrollTop
        const scrollStep=Math.PI / (this.duration/10)
        let count=0
        let currPos
        const start=window.pageYOffset
        const scrollInterval=setInterval(()=>{
            if(document.body.scrollTop!=to){
                count++
                currPos=start+diff*(.5-.5*Math.cos(count*scrollStep))
                document.body.scrollTop=currPos
            }else{clearInterval(scrollInterval)}
        },10)
    }
}

UPDATE

There is a problem with Firefox as mentioned here. Therefore, to make it work on Firefox, I implemented the following code. It works fine on Chromium-based browsers and also Firefox.

export class SScroll{
    constructor(){
        this.delay=501      //ms
        this.duration=500   //ms
        this.lastClick=0
    }
    lastClick
    delay
    duration
    scrollTo=(destID)=>{
        /* To prevent "bounce" */
        /* https://stackoverflow.com/a/28610565/3405291 */
        if(this.lastClick>=(Date.now()-this.delay)){return}

        this.lastClick=Date.now()
        const dest=document.getElementById(destID)
        const to=dest.offsetTop
        if((document.body.scrollTop || document.documentElement.scrollTop || 0)==to){return}

        const diff=to-(document.body.scrollTop || document.documentElement.scrollTop || 0)
        const scrollStep=Math.PI / (this.duration/10)
        let count=0
        let currPos
        const start=window.pageYOffset
        const scrollInterval=setInterval(()=>{
            if((document.body.scrollTop || document.documentElement.scrollTop || 0)!=to){
                count++
                currPos=start+diff*(.5-.5*Math.cos(count*scrollStep))
                /* https://stackoverflow.com/q/28633221/3405291 */
                /* To support both Chromium-based and Firefox */
                document.body.scrollTop=currPos
                document.documentElement.scrollTop=currPos
            }else{clearInterval(scrollInterval)}
        },10)
    }
}

To make matplotlib inline by default in Jupyter (IPython 3):

1. Edit file ~/.ipython/profile_default/ipython_config.py

2. Add line c.InteractiveShellApp.matplotlib = 'inline'

Please note that adding this line to ipython_notebook_config.py would not work. Otherwise it works well with Jupyter and IPython 3.1.0

You can using dict , fillna with different value for different column

df.fillna({'a':0,'b':0})

1  2.0  5.0  NaN
2  3.0  0.0  7.0
3  0.0  6.0  8.0

After assign it back

df=df.fillna({'a':0,'b':0})
df

When you're using Maven in an IDE you often find the need for your IDE to resolve source code and Javadocs for your library dependencies. There's an easy way to accomplish that goal.

mvn dependency:sources
mvn dependency:resolve -Dclassifier=javadoc

The first command will attempt to download source code for each of the dependencies in your pom file.

The second command will attempt to download the Javadocs.

Maven is at the mercy of the library packagers here. So some of them won't have source code packaged and many of them won't have Javadocs.

In case you have a lot of dependencies it might also be a good idea to use inclusions/exclusions to get specific artifacts, the following command will for example only download the sources for the dependency with a specific artifactId:

mvn dependency:sources -DincludeArtifactIds=guava

My solution is to use ggplot2. It takes care of these types of things automatically. The biggest thing is to arrange the data appropriately.

y1 <- c(100, 200, 300, 400, 500)
y2 <- c(1, 2, 3, 4, 5)
x <- c(1, 2, 3, 4, 5)
df <- data.frame(x=rep(x,2), y=c(y1, y2), class=c(rep("y1", 5), rep("y2", 5)))

Then use ggplot2 to plot it

library(ggplot2)
ggplot(df, aes(x=x, y=y, color=class)) + geom_point()

This is saying plot the data in df, and separate the points by class.

The plot generated is

Because the inequality operator in VBA is <>

If strTest <> "" Then
    .....

the operator != is used in C#, C++.

Also, you can de-serialize data into an object. This doesn't go through the class Constructor !

UPDATED : Thanks Tom for pointing that out in your comment ! And Michael also experimented.

It goes through the constructor of the most derived non-serializable superclass.
And when that class has no no-args constructor, a InvalidClassException is thrown upon de-serialization.

Please see Tom's answer for a complete treatment of all cases ;-)
is there any other way of creating an object without using "new" keyword in java

This worked for me:

GRANT USAGE ON *.* TO 'username'@'localhost';
DROP USER 'username'@'localhost';

This creates the user if it doesn't already exist (and grants it a harmless privilege), then deletes it either way. Found solution here: http://bugs.mysql.com/bug.php?id=19166

Updates: @Hao recommends adding IDENTIFIED BY; @andreb (in comments) suggests disabling NO_AUTO_CREATE_USER.

You can use aggregation with the new $objectToArray aggregation operator in version 3.4.4 to convert all top key-value pairs into document arrays, followed by $unwind and $group with $addToSet to get distinct keys across the entire collection. (Use $$ROOT for referencing the top level document.)

db.things.aggregate([
  {"$project":{"arrayofkeyvalue":{"$objectToArray":"$$ROOT"}}},
  {"$unwind":"$arrayofkeyvalue"},
  {"$group":{"_id":null,"allkeys":{"$addToSet":"$arrayofkeyvalue.k"}}}
])

You can use the following query for getting keys in a single document.

db.things.aggregate([
  {"$match":{_id: "<<ID>>"}}, /* Replace with the document's ID */
  {"$project":{"arrayofkeyvalue":{"$objectToArray":"$$ROOT"}}},
  {"$project":{"keys":"$arrayofkeyvalue.k"}}
])

Do the following, download SQLLite Database Browser from here:

Locate your db. file in your phone.

Then, as soon you install the program go to: "Browse Data", you will see all the SMS there!!

You can actually export the data to an excel file or SQL.

Or, in order to avoid modifying slowFunc (say you don't have access to the source code for instance):

var source = new CancellationTokenSource(); //original code
source.Token.Register(CancelNotification); //original code
source.CancelAfter(TimeSpan.FromSeconds(1)); //original code
var completionSource = new TaskCompletionSource<object>(); //New code
source.Token.Register(() => completionSource.TrySetCanceled()); //New code
var task = Task<int>.Factory.StartNew(() => slowFunc(1, 2), source.Token); //original code

//original code: await task;  
await Task.WhenAny(task, completionSource.Task); //New code

You can also use nice extension methods from https://github.com/StephenCleary/AsyncEx and have it looks as simple as:

await Task.WhenAny(task, source.Token.AsTask());

As far as I know, the only way to get the name would be

Mode.mode1.name();

If you really need it this way, however, you could do:

public enum Modes {
    mode1 ("Mode1"),
    mode2 ("Mode2"),
    mode3 ("Mode3");

    private String name;       

    private Modes(String s) {
        name = s;
    }
}

You don't need a library to do this. You can do it with Java itself.

Chris Campbell has an excellent and detailed write-up on scaling images - see this article.

Chet Haase and Romain Guy also have a detailed and very informative write-up of image scaling in their book, Filthy Rich Clients.

Multiple Scope Parameters:

This should answer Greg's question.

A DataSet already contains DataTables. You can just use:

DataTable firstTable = dataSet.Tables[0];

or by name:

DataTable customerTable = dataSet.Tables["Customer"];

Note that you should have using statements for your SQL code, to ensure the connection is disposed properly:

using (SqlConnection conn = ...)
{
    // Code here...
}

You can use extension methods to achive this.

public static ObjRemoverExtension {
    public static void DeleteObj<T>(this T obj) where T: new()
    {
        obj = null;
    }
}

And then you just import it in a desired source file and use on any object. GC will collect it. Like this:Car.DeleteObj()

EDIT Sorry didn't notice the method of class/all references part, but i'll leave it anyway.

A class in HTML means that in order to set attributes to it in CSS, you simply need to add a period in front of it.
For example, the CSS code of that html code may be:

.clear {     height: 50px;     width: 25px; } 

Also, if you, as suggested by abiessu, are attempting to add the CSS clear: both; attribute to the div to prevent anything from floating to the left or right of this div, you can use this CSS code:

.clear {     clear: both; } 

You can use this command:

$ dpkg -s libgtk2.0-0|grep '^Version'

Try with Beautifulsoup:

from BeautifulSoup import BeautifulSoup
import urllib2
import re

html_page = urllib2.urlopen("http://www.yourwebsite.com")
soup = BeautifulSoup(html_page)
for link in soup.findAll('a'):
    print link.get('href')

In case you just want links starting with http://, you should use:

soup.findAll('a', attrs={'href': re.compile("^http://")})

In Python 3 with BS4 it should be:

from bs4 import BeautifulSoup
import urllib.request

html_page = urllib.request.urlopen("http://www.yourwebsite.com")
soup = BeautifulSoup(html_page, "html.parser")
for link in soup.findAll('a'):
    print(link.get('href'))

For me it was an error higher up in the web.config above the system.web.

the file blah didn't exist so it was throwing an error at that point. Because it hadn't yet got to the System.Web section yet it was using the server default setting for CUstomErrors (On)

I find it useful to have a class, derived from threading.Thread, to encapsulate my thread functionality. You simply provide your own main loop in an overridden version of run() in this class. Calling start() arranges for the object’s run() method to be invoked in a separate thread.

Inside the main loop, periodically check whether a threading.Event has been set. Such an event is thread-safe.

Inside this class, you have your own join() method that sets the stop event object before calling the join() method of the base class. It can optionally take a time value to pass to the base class's join() method to ensure your thread is terminated in a short amount of time.

import threading
import time

class MyThread(threading.Thread):
    def __init__(self, sleep_time=0.1):
        self._stop_event = threading.Event()
        self._sleep_time = sleep_time
        """call base class constructor"""
        super().__init__()

    def run(self):
        """main control loop"""
        while not self._stop_event.isSet():
            #do work
            print("hi")
            self._stop_event.wait(self._sleep_time)

    def join(self, timeout=None):
        """set stop event and join within a given time period"""
        self._stop_event.set()
        super().join(timeout)


if __name__ == "__main__":
    t = MyThread()
    t.start()

    time.sleep(5)

    t.join(1) #wait 1s max

Having a small sleep inside the main loop before checking the threading.Event is less CPU intensive than looping continuously. You can have a default sleep time (e.g. 0.1s), but you can also pass the value in the constructor.

Here is how I would do it if working with a large number of "to remove" values that would take a long time to manually remove.

• -Put Original List in Column A -Put To Remove list in Column B -Select both columns, then "Conditional Formatting"
  -Select "Hightlight Cells Rules" --> "Duplicate Values"
  -The duplicates should be hightlighted in both columns
  -Then select Column A and then "Sort & Filter" ---> "Custom Sort"
  -In the dialog box that appears, select the middle option "Sort On" and pick "Cell Color"
  -Then select the next option "Sort Order" and choose "No Cell Color" "On bottom"
  -All the highlighted cells should be at the top of the list. -Select all the highlighted cells by scrolling down the list, then click delete.

At the Maven repo, there are samples to add the dependency in maven, sbt, gradle, etc.

https://mvnrepository.com/artifact/org.apache.httpcomponents/httpcore/4.4.11

ie for Maven, you just create a project, for example

mvn archetype:generate -DarchetypeGroupId=org.apache.maven.archetypes -DarchetypeArtifactId=maven-archetype-quickstart -DarchetypeVersion=1.4

then look at the pom.xml, then at the library at the dependencies xml element:

<dependency>
    <groupId>org.apache.httpcomponents</groupId>
    <artifactId>httpcore</artifactId>
    <version>4.4.11</version>
</dependency>

For sbt do something like

sbt new scala/hello-world.g8

then edit the build.sbt to add the library

libraryDependencies += "org.apache.httpcomponents" % "httpcore" % "4.4.11"

Typescript distinguishes two different kinds of modules: Internal modules are used to structure your code internally. At compile-time, you have to bring internal modules into scope using reference paths:

/// <reference path='moo.ts'/>

class bar extends moo.foo {
}

On the other hand, external modules are used to refernence external source files that are to be loaded at runtime using CommonJS or AMD. In your case, to use external module loading you have to do the following:

moo.ts

export class foo {
    test: number;
} 

app.ts

import moo = module('moo');
class bar extends moo.foo {
  test2: number;
}

Note the different way of brining the code into scope. With external modules, you have to use module with the name of the source file that contains the module definition. If you want to use AMD modules, you have to call the compiler as follows:

tsc --module amd app.ts

This then gets compiled to

var __extends = this.__extends || function (d, b) {
    function __() { this.constructor = d; }
    __.prototype = b.prototype;
    d.prototype = new __();
}
define(["require", "exports", 'moo'], function(require, exports, __moo__) {
    var moo = __moo__;

    var bar = (function (_super) {
        __extends(bar, _super);
        function bar() {
            _super.apply(this, arguments);

        }
        return bar;
    })(moo.foo);
})    

In the example a string is executed as code using the exec function.

import sys
import StringIO

# create file-like string to capture output
codeOut = StringIO.StringIO()
codeErr = StringIO.StringIO()

code = """
def f(x):
    x = x + 1
    return x

print 'This is my output.'
"""

# capture output and errors
sys.stdout = codeOut
sys.stderr = codeErr

exec code

# restore stdout and stderr
sys.stdout = sys.__stdout__
sys.stderr = sys.__stderr__

print f(4)

s = codeErr.getvalue()

print "error:\n%s\n" % s

s = codeOut.getvalue()

print "output:\n%s" % s

codeOut.close()
codeErr.close()

In Rails you can print the result in the View by using the debug' Helper ActionView::Helpers::DebugHelper

I have never developed with HangOut. I ran into the same problems with FB-login and I was trying so hard to get it to click programatically. Then later I discovered that the sdk won't allow you to programatically click the button because of some security reasons. The user has to physically click on the button. This also happens with async asp fileupload button. So please check if HangOut does allow you to programatically click a buttton. All above codes are correct and they should work. If you dig deep enough you will see that my answer is the right answer for your situation you.

Add the following CSS style after loading Bootstrap:

.table-striped>tbody>tr:nth-child(odd)>td, 
.table-striped>tbody>tr:nth-child(odd)>th {
   background-color: red; // Choose your own color here
 }

From here.

the SQL standard requires that HAVING must reference only columns in the GROUP BY clause or columns used in aggregate functions

as opposed to the WHERE clause which is applied to database rows

You can find the answer here: Is there a minlength validation attribute in HTML5?

Therefore this should do the job:

<input pattern=".{6,6}">

Even without importing swing, you can get the call in one, all be it long, string. Otherwise just use the swing import and simple call:

JOptionPane.showMessageDialog(null, "Thank you for using Java", "Yay, java", JOptionPane.PLAIN_MESSAGE);

Easy enough.

If the label is in a table row you can do this to hide the row:

('.InputFile').parent().Hide()

You can refine your selector as you need and then get the table row that contains that element.

JQuery Selectors help: http://api.jquery.com/category/selectors/

EDIT This is the correct way to do it.

    ('.InputFile').parents('tr').hide()

(Just assumption, less info of Exception stacktrace)

I think, this line, incercari.setText(valIncercari); throws Exception because valIncercari is int

So it should be,

incercari.setText(valIncercari+"");

Or

incercari.setText(Integer.toString(valIncercari));

Through jQuery.ready function you can specify function that's executed when DOM is loaded. Whole DOM, not any div you want.

So, you should use ready in a bit different way

$.ready(function() {
    createGrid();
});

This is in case when you dont use AJAX to load your div

This can also be done through the SSMS GUI.

1. Put your table in design view (Right click on table in object explorer->Design)
2. Add a column to the table (or click on the column you want to update if it already exists)
3. In Column Properties, enter (getdate()) in Default Value or Binding field as pictured below

Yes, in my perspective there is no reason why you should write your own. Most of the Open Source BPM/Workflow frameworks are extremely flexible, you just need to learn the basics. If you choose jBPM you will get much more than a simple workflow engine, so it depends what are you trying to build.

Late to the game but here a handy little category I use that accounts for decimal places and the local symbol used for it. link to its gist here

@interface NSString (Extension)

- (BOOL) isAnEmail;
- (BOOL) isNumeric;

@end

@implementation NSString (Extension)

/**
 *  Determines if the current string is a valid email address.
 *
 *  @return BOOL - True if the string is a valid email address.
 */

{
    NSString *emailRegex = @"[A-Z0-9a-z._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,4}";
    NSPredicate *emailTest = [NSPredicate predicateWithFormat:@"SELF MATCHES %@", emailRegex];

    return [emailTest evaluateWithObject:self];
}

/**
 *  Determines if the current NSString is numeric or not. It also accounts for the localised (Germany for example use "," instead of ".") decimal point and includes these as a valid number.
 *
 *  @return BOOL - True if the string is numeric.
 */

- (BOOL) isNumeric
{
    NSString *localDecimalSymbol = [[NSLocale currentLocale] objectForKey:NSLocaleDecimalSeparator];
    NSMutableCharacterSet *decimalCharacterSet = [NSMutableCharacterSet characterSetWithCharactersInString:localDecimalSymbol];
    [decimalCharacterSet formUnionWithCharacterSet:[NSCharacterSet alphanumericCharacterSet]];

    NSCharacterSet* nonNumbers = [decimalCharacterSet invertedSet];
    NSRange r = [self rangeOfCharacterFromSet: nonNumbers];

    if (r.location == NSNotFound)
    {
        // check to see how many times the decimal symbol appears in the string. It should only appear once for the number to be numeric.
        int numberOfOccurances = [[self componentsSeparatedByString:localDecimalSymbol] count]-1;
        return (numberOfOccurances > 1) ? NO : YES;
    }
    else return NO;

Almost by definition, the client-side JavaScript is not at the receiving end of a http request, so it has no headers to read. Most commonly, your JavaScript is the result of an http response. If you are trying to get the values of the http request that generated your response, you'll have to write server side code to embed those values in the JavaScript you produce.

It gets a little tricky to have server-side code generate client side code, so be sure that is what you need. For instance, if you want the User-agent information, you might find it sufficient to get the various values that JavaScript provides for browser detection. Start with navigator.appName and navigator.appVersion.

Straight after the $wpdb->insert() that does the insert, do this:

$lastid = $wpdb->insert_id;

More information about how to do things the WordPress way can be found in the WordPress codex. The details above were found here on the wpdb class page

I just ran into this on .NET 4.6.1 and it ultimately had a simple solution - I removed (actually commented out) the section in the web.config and the web forms application came back to life. See what-exactly-does-system-codedom-compilers-do-in-web-config-in-mvc-5 for more info.

It worked for me.

I answered this already, but some reason the answer was converted to a comment. Nevertheless, this is the most efficient solution:

Not being able to include (and propagate) NaNs in groups is quite aggravating. Citing R is not convincing, as this behavior is not consistent with a lot of other things. Anyway, the dummy hack is also pretty bad. However, the size (includes NaNs) and the count (ignores NaNs) of a group will differ if there are NaNs.

dfgrouped = df.groupby(['b']).a.agg(['sum','size','count'])

dfgrouped['sum'][dfgrouped['size']!=dfgrouped['count']] = None

When these differ, you can set the value back to None for the result of the aggregation function for that group.

Set following php parameters to same value in seconds:

session.cookie_lifetime
session.gc_maxlifetime

in php.ini, .htaccess or for example with

ini_set('session.cookie_lifetime', 86400);
ini_set('session.gc_maxlifetime', 86400);

for a day.

Links:

http://www.php.net/manual/en/session.configuration.php

http://www.php.net/manual/en/function.ini-set.php

Here are some options:

1- Use if then else in one line, it is possible.

if [[ "$2" == "raiz" ]] || [[ "$2" == '.' ]]; then pasta=''; else pasta="$2"; fi

2- Write a function like this:

 # Once upon a time, there was an 'iif' function in MS VB ...

function iif(){
  # Echoes $2 if 1,banana,true,etc and $3 if false,null,0,''
  case $1 in ''|false|FALSE|null|NULL|0) echo $3;;*) echo $2;;esac
}

use inside script like this

result=`iif "$expr" 'yes' 'no'`

# or even interpolating:
result=`iif "$expr" "positive" "negative, because $1 is not true"` 

3- Inspired in the case answer, a more flexible and one line use is:

 case "$expr" in ''|false|FALSE|null|NULL|0) echo "no...$expr";;*) echo "yep $expr";;esac

 # Expression can be something like:     
   expr=`expr "$var1" '>' "$var2"`

Important points in my experience:

• every resource accessed by the server must be in an executable and readable directory, hence the xx5 in every chmod in other answers.
• most of the time the webserver (apache in my case) is running neither as the user nor in the group that owns the directory, so again xx5 or chmod o+rx is necessary.

But the greater conclusion I reached is start from little to more.

For example, if http://myserver.com/sites/all/resources/assets/css/bootstrap.css yields a 403 error, see if http://myserver.com/ works, then sites, then sites/all, then sites/all/resources, and so on.

It will help if your server has directory indexes enable:

• In Apache: Options +Indexes

This instruction might also be in the .htaccess of your webserver public_html folder.

Uri.parse(STRING);

See doc:

String: an RFC 2396-compliant, encoded URI

Url must be canonicalized before using, like this:

Uri.parse(Uri.decode(STRING));

If your xml is written by java.lang.String you can just using HttpClient in this way

    public void post() throws Exception{
        HttpClient client = new DefaultHttpClient();
        HttpPost post = new HttpPost("http://www.baidu.com");
        String xml = "<xml>xxxx</xml>";
        HttpEntity entity = new ByteArrayEntity(xml.getBytes("UTF-8"));
        post.setEntity(entity);
        HttpResponse response = client.execute(post);
        String result = EntityUtils.toString(response.getEntity());
    }

pay attention to the Exceptions.

BTW, the example is written by the httpclient version 4.x

Here I want my no to limit in 4 digit like if it is 1 it should show as 0001,if it 11 it should show as 0011..Below are the code.

        reciptno=1;//Pass only integer.

        string formatted = string.Format("{0:0000}", reciptno);

        TxtRecNo.Text = formatted;//Output=0001..

I implemented this code to generate Money receipt no.

Based on the Answer marked as correct, adding my answer. Small code added just to reset the indices-

$input = array_values(array_map("unserialize", array_unique(array_map("serialize", $inputArray))));

using System.Collections.Generic;
using System.Linq;

namespace YourProject.Extensions
{
    public static class ListExtensions
    {
        public static bool SetwiseEquivalentTo<T>(this List<T> list, List<T> other)
            where T: IEquatable<T>
        {
            if (list.Except(other).Any())
                return false;
            if (other.Except(list).Any())
                return false;
            return true;
        }
    }
}

Sometimes you only need to know if two lists are different, and not what those differences are. In that case, consider adding this extension method to your project. Note that your listed objects should implement IEquatable!

Usage:

public sealed class Car : IEquatable<Car>
{
    public Price Price { get; }
    public List<Component> Components { get; }

    ...
    public override bool Equals(object obj)
        => obj is Car other && Equals(other);

    public bool Equals(Car other)
        => Price == other.Price
            && Components.SetwiseEquivalentTo(other.Components);

    public override int GetHashCode()
        => Components.Aggregate(
            Price.GetHashCode(),
            (code, next) => code ^ next.GetHashCode()); // Bitwise XOR
}

Whatever the Component class is, the methods shown here for Car should be implemented almost identically.

It's very important to note how we've written GetHashCode. In order to properly implement IEquatable, Equals and GetHashCode must operate on the instance's properties in a logically compatible way.

Two lists with the same contents are still different objects, and will produce different hash codes. Since we want these two lists to be treated as equal, we must let GetHashCode produce the same value for each of them. We can accomplish this by delegating the hashcode to every element in the list, and using the standard bitwise XOR to combine them all. XOR is order-agnostic, so it doesn't matter if the lists are sorted differently. It only matters that they contain nothing but equivalent members.

Note: the strange name is to imply the fact that the method does not consider the order of the elements in the list. If you do care about the order of the elements in the list, this method is not for you!

"Editor's" note: This post may contain outdated information. Please see comments and this question regarding changes in Git since 1.6.1.

Symlinked directories:

It's important to note what happens when there is a directory which is a soft link. Any Git pull with an update removes the link and makes it a normal directory. This is what I learnt hard way. Some insights here and here.

Example

Before

 ls -l
 lrwxrwxrwx 1 admin adm   29 Sep 30 15:28 src/somedir -> /mnt/somedir

git add/commit/push

It remains the same

After git pull AND some updates found

 drwxrwsr-x 2 admin adm 4096 Oct  2 05:54 src/somedir

// The answer that I was looking for when searching
public void Answer()
{
    IEnumerable<YourClass> first = this.GetFirstIEnumerableList();
    // Assign to empty list so we can use later
    IEnumerable<YourClass> second = new List<YourClass>();

    if (IwantToUseSecondList)
    {
        second = this.GetSecondIEnumerableList();  
    }
    IEnumerable<SchemapassgruppData> concatedList = first.Concat(second);
}

In addition, you can use it to check if the dynamic allocation was successful.

Code example:

int ** p;
p = new int * [5];      // Dynamic array (size 5) of pointers to int
for (int i = 0; i < 5; ++i) {
    p[i] = new int[3]; // Each i(ptr) is now pointing to a dynamic
                       // array (size 3) of actual int values
}

assert (p);            // Check the dynamic allocation.

Similar to:

if (p == NULL) {
    cout << "dynamic allocation failed" << endl;
    exit(1);
}

Unlike maths-on-paper notation, most programming languages (Java included) need a * sign to do multiplication. Your distance calculation should therefore read:

distance = Math.sqrt((x1-x2)*(x1-x2) + (y1-y2)*(y1-y2));

Or alternatively:

distance = Math.sqrt(Math.pow((x1-x2), 2) + Math.pow((y1-y2), 2));

Just send xml bytes directly:

#!/usr/bin/env python2
# -*- coding: utf-8 -*-
import requests

xml = """<?xml version='1.0' encoding='utf-8'?>
<a>?</a>"""
headers = {'Content-Type': 'application/xml'} # set what your server accepts
print requests.post('http://httpbin.org/post', data=xml, headers=headers).text

Output

{
  "origin": "x.x.x.x",
  "files": {},
  "form": {},
  "url": "http://httpbin.org/post",
  "args": {},
  "headers": {
    "Content-Length": "48",
    "Accept-Encoding": "identity, deflate, compress, gzip",
    "Connection": "keep-alive",
    "Accept": "*/*",
    "User-Agent": "python-requests/0.13.9 CPython/2.7.3 Linux/3.2.0-30-generic",
    "Host": "httpbin.org",
    "Content-Type": "application/xml"
  },
  "json": null,
  "data": "<?xml version='1.0' encoding='utf-8'?>\n<a>\u0431</a>"
}

You can as well do:

git checkout --theirs /path/to/file

to keep the remote file, and:

git checkout --ours /path/to/file

to keep local file.

Then git add them and everything is done.

Edition: Keep in mind that this is for a merge scenario. During a rebase --theirs refers to the branch where you've been working.

Just in case you are (for whatever reason) unable to use curl nor file_get_contents, you can work around:

$img = imagecreatefrompng('...');
ob_start();
imagepng($img);
$bin = ob_get_clean();
$b64 = base64_encode($bin);

Try this:

location / {
    root /path/to/root;
    expires 30d;
    access_log off;
}

location ~* ^.*\.php$ {
    if (!-f $request_filename) {
        return 404;
    }
    proxy_set_header X-Real-IP  $remote_addr;
    proxy_set_header Host $host;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
    proxy_pass http://127.0.0.1:8080;
}

Hopefully it works. Regular expressions have higher priority than plain strings, so all requests ending in .php should be forwared to Apache if only a corresponding .php file exists. Rest will be handled as static files. The actual algorithm of evaluating location is here.

First, always sudo nginx -t to verify your config files are good.

I ran into the same problem. The reason I had the issue was twofold. First, I had accidentally copied a log file into my site-enabled folder. I deleted the log file and made sure that all the files in sites-enabled were proper nginx site configs. I also noticed two of my virtual hosts were listening for the same domain. So I made sure that each of my virtual hosts had unique domain names.

sudo service nginx restart

Then it worked.

I had same issue in my case, the cause was connection was not embedded and incompatibility of Oracle Client.

SOLUTION:

My Environment:SQL SERVER 2014 64bit Oracle Client 32 bit

1. For include/embed Connection

   • open package
   • right click on connection
   • select "Convert to project" option

2. for SQL SSIS Catalog/Job schedule set the configuration follow steps in picture

   • Right on 'SQL JOB->Step" or "SSIS Catalog-->Package-->Execute" and select "Properties"
   • Select Configuration-->Advanced tab
   • Checked 32-bit runtime

I tried to post detail step by step pictures, but Stack Overflow does not allow that due to reputation. Hope I later will update this post.

If you are interested only in the last X lines, you can use the "tail" command like this.

$ tail -n XXXXX yourlogfile.log >> mycroppedfile.txt

This will save the last XXXXX lines of your log file to a new file called "mycroppedfile.txt"

It's pretty straightforward using [ to extract:

grep will give you the position in which it matched your search pattern (unless you use value = TRUE).

grep("^G45", My.Data$x)
# [1] 2

Since you're searching within the values of a single column, that actually corresponds to the row index. So, use that with [ (where you would use My.Data[rows, cols] to get specific rows and columns).

My.Data[grep("^G45", My.Data$x), ]
#      x y
# 2 G459 2

The help-page for subset shows how you can use grep and grepl with subset if you prefer using this function over [. Here's an example.

subset(My.Data, grepl("^G45", My.Data$x))
#      x y
# 2 G459 2

As of R 3.3, there's now also the startsWith function, which you can again use with subset (or with any of the other approaches above). According to the help page for the function, it's considerably faster than using substring or grepl.

subset(My.Data, startsWith(as.character(x), "G45"))
#      x y
# 2 G459 2

Is this what you need?

If you want a separate .js file to better organize your routes, just create a variable in the app.js file pointing to its location in the filesystem:

var wf = require(./routes/wf);

then,

app.get('/wf', wf.foo );

where .foo is some function declared in your wf.js file. e.g

// wf.js file 
exports.foo = function(req,res){

          console.log(` request object is ${req}, response object is ${res} `);

}

In Font Awesome 5 it can be done using pure CSS as in some of the above answers with some modifications.

ul {
  list-style-type: none;
}

li:before {
  position: absolute;
  font-family: 'Font Awesome 5 free';
          /*  Use the Name of the Font Awesome free font, e.g.:
           - 'Font Awesome 5 Free' for Regular and Solid symbols;
           - 'Font Awesome 5 Brand' for Brands symbols.
           - 'Font Awesome 5 Pro' for Regular and Solid symbols (Professional License);
          */
  content: "\f1fc"; /* Unicode value of the icon to use: */
  font-weight: 900; /* This is important, change the value according to the font family name
                       used above. See the link below  */
  color: red;
}

Without the correct font-weight, it will only show a blank square.

If you are using an IDE like eclipse, you can use this easy way.

Right click on the project -> Team - Show history

In that right click on the revision id for your commit and select 'Set commit properties'.

You can modify the message as you want from here.

You can use the following

WebDriverWait wait = new WebDriverWait(driver, new TimeSpan(0,0,5));
wait.Until(ExpectedConditions.ElementToBeClickable((By.Id("login")));

IEnumerable implements GetEnumerator. When called, that method will return an IEnumerator which implements MoveNext, Reset and Current.

Thus when your class implements IEnumerable, you are saying that you can call a method (GetEnumerator) and get a new object returned (an IEnumerator) you can use in a loop such as foreach.

The Swift 3.0 beta official documentation has provided its standard solution for this situation under the title String.UTF16View in section UTF16View Elements Match NSString Characters title

Loop through the Items and Add to the Collection. You can use the Add method

List<string>items=new List<string>();
using (var con= new SqlConnection("yourConnectionStringHere")
{
    string qry="SELECT Column1 FROM Table1";
    var cmd= new SqlCommand(qry, con);
    cmd.CommandType = CommandType.Text;
    con.Open();
    using (SqlDataReader objReader = cmd.ExecuteReader())
    {
        if (objReader.HasRows)
        {              
            while (objReader.Read())
            {
              //I would also check for DB.Null here before reading the value.
               string item= objReader.GetString(objReader.GetOrdinal("Column1"));
               items.Add(item);                  
            }
        }
    }
}

Your interior <div> elements should likely both be float:left. Divs size to 100% the size of their container width automatically. Try using display:inline-block instead of width:auto on the container div. Or possibly float:left the container and also apply overflow:auto. Depends on what you're after exactly.

Just use replace instead of replaceAll (which expects regex):

str = str.replace(",", ".");

or

str = str.replace(',', '.');

(replace takes as input either char or CharSequence, which is an interface implemented by String)

Also note that you should reassign the result

Differently from Dan, I consider his answer quite elegant... but unfortunately it is also very very inefficient. So, since the question mentioned "a large csv file", let me suggest to try in a shell Dan's solution:

time python -c "import pandas as pd;
df = pd.DataFrame(['a b c']*100000, columns=['col']);
print df['col'].apply(lambda x : pd.Series(x.split(' '))).head()"

... compared to this alternative:

time python -c "import pandas as pd;
from scipy import array, concatenate;
df = pd.DataFrame(['a b c']*100000, columns=['col']);
print pd.DataFrame(concatenate(df['col'].apply( lambda x : [x.split(' ')]))).head()"

... and this:

time python -c "import pandas as pd;
df = pd.DataFrame(['a b c']*100000, columns=['col']);
print pd.DataFrame(dict(zip(range(3), [df['col'].apply(lambda x : x.split(' ')[i]) for i in range(3)]))).head()"

The second simply refrains from allocating 100 000 Series, and this is enough to make it around 10 times faster. But the third solution, which somewhat ironically wastes a lot of calls to str.split() (it is called once per column per row, so three times more than for the others two solutions), is around 40 times faster than the first, because it even avoids to instance the 100 000 lists. And yes, it is certainly a little ugly...

EDIT: this answer suggests how to use "to_list()" and to avoid the need for a lambda. The result is something like

time python -c "import pandas as pd;
df = pd.DataFrame(['a b c']*100000, columns=['col']);
print pd.DataFrame(df.col.str.split().tolist()).head()"

which is even more efficient than the third solution, and certainly much more elegant.

EDIT: the even simpler

time python -c "import pandas as pd;
df = pd.DataFrame(['a b c']*100000, columns=['col']);
print pd.DataFrame(list(df.col.str.split())).head()"

works too, and is almost as efficient.

EDIT: even simpler! And handles NaNs (but less efficient):

time python -c "import pandas as pd;
df = pd.DataFrame(['a b c']*100000, columns=['col']);
print df.col.str.split(expand=True).head()"

Instead of ng-options="product as product.label for product in products"> in the select element, you can even use this:

<option ng-repeat="product in products" value="{{product.label}}">{{product.label}}

which works just fine as well.

If you want to find the rows that have any of the values in a vector, one option is to loop the vector (lapply(v1,..)), create a logical index of (TRUE/FALSE) with (==). Use Reduce and OR (|) to reduce the list to a single logical matrix by checking the corresponding elements. Sum the rows (rowSums), double negate (!!) to get the rows with any matches.

indx1 <- !!rowSums(Reduce(`|`, lapply(v1, `==`, df)), na.rm=TRUE)

Or vectorise and get the row indices with which with arr.ind=TRUE

indx2 <- unique(which(Vectorize(function(x) x %in% v1)(df),
                                     arr.ind=TRUE)[,1])

Benchmarks

I didn't use @kristang's solution as it is giving me errors. Based on a 1000x500 matrix, @konvas's solution is the most efficient (so far). But, this may vary if the number of rows are increased

val <- paste0('M0', 1:1000)
set.seed(24)
df1 <- as.data.frame(matrix(sample(c(val, NA), 1000*500, 
  replace=TRUE), ncol=500), stringsAsFactors=FALSE) 
set.seed(356)
v1 <- sample(val, 200, replace=FALSE)

 konvas <- function() {apply(df1, 1, function(r) any(r %in% v1))}
 akrun1 <- function() {!!rowSums(Reduce(`|`, lapply(v1, `==`, df1)),
               na.rm=TRUE)}
 akrun2 <- function() {unique(which(Vectorize(function(x) x %in% 
              v1)(df1),arr.ind=TRUE)[,1])}


 library(microbenchmark)
 microbenchmark(konvas(), akrun1(), akrun2(), unit='relative', times=20L)
 #Unit: relative

Assuming you're the administrator of the machine, Ubuntu has granted you the right to sudo to run any command as any user.
Also assuming you did not restrict the rights in the pg_hba.conf file (in the /etc/postgresql/9.1/main directory), it should contain this line as the first rule:

# Database administrative login by Unix domain socket  
local   all             postgres                                peer

(About the file location: 9.1 is the major postgres version and main the name of your "cluster". It will differ if using a newer version of postgres or non-default names. Use the pg_lsclusters command to obtain this information for your version/system).

Anyway, if the pg_hba.conf file does not have that line, edit the file, add it, and reload the service with sudo service postgresql reload.

Then you should be able to log in with psql as the postgres superuser with this shell command:

sudo -u postgres psql

Once inside psql, issue the SQL command:

ALTER USER postgres PASSWORD 'newpassword';

In this command, postgres is the name of a superuser. If the user whose password is forgotten was ritesh, the command would be:

ALTER USER ritesh PASSWORD 'newpassword';

References: PostgreSQL 9.1.13 Documentation, Chapter 19. Client Authentication

Keep in mind that you need to type postgres with a single S at the end

If leaving the password in clear text in the history of commands or the server log is a problem, psql provides an interactive meta-command to avoid that, as an alternative to ALTER USER ... PASSWORD:

\password username

It asks for the password with a double blind input, then hashes it according to the password_encryption setting and issue the ALTER USER command to the server with the hashed version of the password, instead of the clear text version.

The innerText property returns the actual text value of an html element while the innerHTML returns the HTML content. Example below:

var element = document.getElementById('hello');_x000D_
element.innerText = '<strong> hello world </strong>';_x000D_
console.log('The innerText property will not parse the html tags as html tags but as normal text:\n' + element.innerText);_x000D_
_x000D_
console.log('The innerHTML element property will encode the html tags found inside the text of the element:\n' + element.innerHTML);_x000D_
element.innerHTML = '<strong> hello world </strong>';_x000D_
console.log('The <strong> tag we put above has been parsed using the innerHTML property so the .innerText will not show them \n ' + element.innerText);_x000D_
console.log(element.innerHTML);

<p id="hello"> Hello world _x000D_
</p>

An advantage of GC in some situations is an annoyance in others; reliance on GC encourages not thinking much about it. In theory, waits until 'idle' period or until it absolutely must, when it will steal bandwidth and cause response latency in your app.

But you don't have to 'not think about it.' Just as with everything else in multithreaded apps, when you can yield, you can yield. So for example, in .Net, it is possible to request a GC; by doing this, instead of less frequent longer running GC, you can have more frequent shorter running GC, and spread out the latency associated with this overhead.

But this defeats the primary attraction of GC which appears to be "encouraged to not have to think much about it because it is auto-mat-ic."

If you were first exposed to programming before GC became prevalent and were comfortable with malloc/free and new/delete, then it might even be the case that you find GC a little annoying and/or are distrustful(as one might be distrustful of 'optimization,' which has had a checkered history.) Many apps tolerate random latency. But for apps that don't, where random latency is less acceptable, a common reaction is to eschew GC environments and move in the direction of purely unmanaged code (or god forbid, a long dying art, assembly language.)

I had a summer student here a while back, an intern, smart kid, who was weaned on GC; he was so adament about the superiorty of GC that even when programming in unmanaged C/C++ he refused to follow the malloc/free new/delete model because, quote, "you shouldn't have to do this in a modern programming language." And you know? For tiny, short running apps, you can indeed get away with that, but not for long running performant apps.

I think you will need to do this as three separate statements. I've been looking around and everything i've seen seems to suggest you can do it if you are adding a column, but not if you are altering one.

ALTER TABLE dbo.MyTable
ADD CONSTRAINT my_Con DEFAULT GETDATE() for created

UPDATE MyTable SET Created = GetDate() where Created IS NULL

ALTER TABLE dbo.MyTable 
ALTER COLUMN Created DATETIME NOT NULL 

Sample XML:

<X>
<Y ATTRIB1=attrib1_value ATTRIB2=attrib2_value/>
</X>

string xPath="/" + X + "/" + Y +
"[@" + ATTRIB1 + "='" + attrib1_value + "']" +
"[@" + ATTRIB2 + "='" + attrib2_value + "']"

XPath Testbed: http://www.whitebeam.org/library/guide/TechNotes/xpathtestbed.rhtm

For MySQL, use:

DESCRIBE name_of_table;

This also works for Oracle as long as you are using SQL*Plus, or Oracle's SQL Developer.

HttpServletRequest request = 
        ((ServletRequestAttributes)RequestContextHolder.getRequestAttributes())
                .getRequest();

Solution 2: inside bean (supported by >= 2.5, Spring 3.0 for singelton beans required!)

@Autowired
private HttpServletRequest request;

Try this. It will work for sure.

var userInput = $('#txt_name').attr('value')

For Word Wrapping in Php Storm 2019.1.3 Just follow below steps:

from top nagivation menu

View -> Active Editor -> Soft-Wrap

that's it so simple.

I use:

Imports System.IO
Dim strPath as String=Directory.GetCurrentDirectory

This problem usually occurs when you are trying to update an entity. For example you have an entity that contains a field called DateCreated which is [Required] and when you insert record, no error is returned but when you want to Update that particular entity, you the get the

datetime2 conversion out of range error.

Now here is the solution:

On your edit view, i.e. edit.cshtml for MVC users all you need to do is add a hidden form field for your DateCreated just below the hidden field for the primary key of the edit data.

Example:

@Html.HiddenFor(model => model.DateCreated)

Adding this to your edit view, you'll never have that error I assure you.

It seems there is a change in how Application.COUNTA works in VB7 vs VB6. I tried the following in both versions of VB.

   ReDim allData(0 To 1, 0 To 15)
   Debug.Print Application.WorksheetFunction.CountA(allData)

In VB6 this returns 0.

Inn VB7 it returns 32

Looks like VB7 doesn't consider COUNTA to be COUNTA anymore.

You're right that you should use the Dispatcher to update controls on the UI thread, and also right that long-running processes should not run on the UI thread. Even if you run the long-running process asynchronously on the UI thread, it can still cause performance issues.

It should be noted that Dispatcher.CurrentDispatcher will return the dispatcher for the current thread, not necessarily the UI thread. I think you can use Application.Current.Dispatcher to get a reference to the UI thread's dispatcher if that's available to you, but if not you'll have to pass the UI dispatcher in to your background thread.

Typically I use the Task Parallel Library for threading operations instead of a BackgroundWorker. I just find it easier to use.

For example,

Task.Factory.StartNew(() => 
    SomeObject.RunLongProcess(someDataObject));

where

void RunLongProcess(SomeViewModel someDataObject)
{
    for (int i = 0; i <= 1000; i++)
    {
        Thread.Sleep(10);

        // Update every 10 executions
        if (i % 10 == 0)
        {
            // Send message to UI thread
            Application.Current.Dispatcher.BeginInvoke(
                DispatcherPriority.Normal,
                (Action)(() => someDataObject.ProgressValue = (i / 1000)));
        }
    }
}

Actually you can do this.

$state.go("state-name", {param-name: param-value}, {location: false, inherit: false});

This is the official documentation about options in state.go

Everything is described there and as you can see this is the way to be done.

The following code worked for me:

public vidOff() {

      let stream = this.video.nativeElement.srcObject;
      let tracks = stream.getTracks();

      tracks.forEach(function (track) {
          track.stop();
      });

      this.video.nativeElement.srcObject = null;
      this.video.nativeElement.stop();
  }

The answer is System.exit(), but not a good thing to do as this aborts the program. Any cleaning up, destroy that you intend to do will not happen.

That code should work, but you need to include the localization in your page (it isn't included by default). Try putting this in your <head> tag, somewhere after you include jQuery and jQueryUI:

<script type="text/javascript"
        src="https://raw.githubusercontent.com/jquery/jquery-ui/master/ui/i18n/datepicker-fr.js">
</script>

I can't find where this is documented on the jQueryUI site, but if you view the source of this demo you'll see that this is how they do it. Also, please note that including this JS file will set the datepicker defaults to French, so if you want only some datepickers to be in French, you'll have to set the default back to English.

You can find all languages here at github: https://github.com/jquery/jquery-ui/tree/master/ui/i18n

And this option?

list_name<-list()
for(i in 1:100){
    paste("orca",i,sep="")->list_name[[i]]
}

It works perfectly. In the example you put, first line is missing, and then gives you the error message.

J2ME Map Route Provider

maps.google.com has a navigation service which can provide you route information in KML format.

To get kml file we need to form url with start and destination locations:

public static String getUrl(double fromLat, double fromLon,
                            double toLat, double toLon) {// connect to map web service
    StringBuffer urlString = new StringBuffer();
    urlString.append("http://maps.google.com/maps?f=d&hl=en");
    urlString.append("&saddr=");// from
    urlString.append(Double.toString(fromLat));
    urlString.append(",");
    urlString.append(Double.toString(fromLon));
    urlString.append("&daddr=");// to
    urlString.append(Double.toString(toLat));
    urlString.append(",");
    urlString.append(Double.toString(toLon));
    urlString.append("&ie=UTF8&0&om=0&output=kml");
    return urlString.toString();
}

Next you will need to parse xml (implemented with SAXParser) and fill data structures:

public class Point {
    String mName;
    String mDescription;
    String mIconUrl;
    double mLatitude;
    double mLongitude;
}

public class Road {
    public String mName;
    public String mDescription;
    public int mColor;
    public int mWidth;
    public double[][] mRoute = new double[][] {};
    public Point[] mPoints = new Point[] {};
}

Network connection is implemented in different ways on Android and Blackberry, so you will have to first form url:

 public static String getUrl(double fromLat, double fromLon,
     double toLat, double toLon)

then create connection with this url and get InputStream.
Then pass this InputStream and get parsed data structure:

 public static Road getRoute(InputStream is)

    MapControl map;
    Road mRoad = new Road();

        double toLat = 50.45, toLon = 30.523333;
        String url = RoadProvider.getUrl(fromLat, fromLon, toLat, toLon);
        InputStream is = getConnection(url);
        mRoad = RoadProvider.getRoute(is);
        map = new MapControl();
        add(new LabelField(mRoad.mName));
        add(new LabelField(mRoad.mDescription));
        add(map);
    }
    protected void onUiEngineAttached(boolean attached) {
        super.onUiEngineAttached(attached);
        if (attached) {
            map.drawPath(mRoad);
        }
    }
    private InputStream getConnection(String url) {
        HttpConnection urlConnection = null;
        InputStream is = null;
        try {
            urlConnection = (HttpConnection) Connector.open(url);
            urlConnection.setRequestMethod("GET");
            is = urlConnection.openInputStream();
        } catch (IOException e) {
            e.printStackTrace();
        }
        return is;
    }
}

On *nix, you can use comm. The answer to the question is:

comm -1 -2 file1.sorted file2.sorted 
# where file1 and file2 are sorted and piped into *.sorted

Here's the full usage of comm:

comm [-1] [-2] [-3 ] file1 file2
-1 Suppress the output column of lines unique to file1.
-2 Suppress the output column of lines unique to file2.
-3 Suppress the output column of lines duplicated in file1 and file2. 

Also note that it is important to sort the files before using comm, as mentioned in the man pages.

About your command line:

root@debian:/# sudo iptables -A INPUT -p tcp --dport 3306 --jump ACCEPT
root@debian:/# iptables-save

• You are already authenticated as root so sudo is redundant there.

• You are missing the -j or --jump just before the ACCEPT parameter (just tought that was a typo and you are inserting it correctly).

About yout question:

If you are inserting the iptables rule correctly as you pointed it in the question, maybe the issue is related to the hypervisor (virtual machine provider) you are using.

If you provide the hypervisor name (VirtualBox, VMWare?) I can further guide you on this but here are some suggestions you can try first:

check your vmachine network settings and:

• if it is set to NAT, then you won't be able to connect from your base machine to the vmachine.

• if it is set to Hosted, you have to configure first its network settings, it is usually to provide them an IP in the range 192.168.56.0/24, since is the default the hypervisors use for this.

• if it is set to Bridge, same as Hosted but you can configure it whenever IP range makes sense for you configuration.

Hope this helps.

we can use data.table library

  library(data.table)
  expr <- data.table(expr)
  expr[cell_type == "hesc"]
  expr[cell_type %in% c("hesc","fibroblast")]

or filter using %like% operator for pattern matching

 expr[cell_type %like% "hesc"|cell_type %like% "fibroblast"]

In case people are searching how to do it in BigQuery:

• An underscore "_" matches a single character or byte.

• You can escape "\", "_", or "%" using two backslashes. For example, "\%". If you are using raw strings, only a single backslash is required. For example, r"\%".

WHERE mycolumn LIKE '%\\_%'

Source: https://cloud.google.com/bigquery/docs/reference/standard-sql/operators

Use the quotemeta function:

$text_to_search = "example text with [foo] and more";
$search_string = quotemeta "[foo]";

print "wee" if ($text_to_search =~ /$search_string/);

In a multi-project solution, If every other thing failed... On the startUp project, check. Dependencies->Assemblies and see if the erring referenced project is there. Remove it and re-build.

For current date just use UNIX_TIMESTAMP() in your MySQL query.

1. Go to your Android project directory

   C:\Users\HP\AndroidStudioProjects
   

   

2. Delete which one you need to delete

3. Restart Android Studio

Although not explicitly mentioned in the discussion, it is NOT necessary to use export when spawning a subshell from inside bash since all the variables are copied into the child process.

Because your else isn't attached to anything. The if without braces only encompasses the single statement that immediately follows it.

if (choice==5)
{
    System.out.println("End of Game\n Thank you for playing with us!");
    break;
}
else
{
   System.out.println("Not a valid choice!\n Please try again...\n");
}

Not using braces is generally viewed as a bad practice because it can lead to the exact problems you encountered.

In addition, using a switch here would make more sense.

int choice;
boolean keepGoing = true;
while(keepGoing)
{
    System.out.println("---> Your choice: ");
    choice = input.nextInt();
    switch(choice)
    {
        case 1: 
            playGame();
            break;
        case 2: 
            loadGame();
            break;
        // your other cases
        // ...
        case 5: 
            System.out.println("End of Game\n Thank you for playing with us!");
            keepGoing = false;
            break;
        default:
            System.out.println("Not a valid choice!\n Please try again...\n");
     }
 }         

Note that instead of an infinite for loop I used a while(boolean), making it easy to exit the loop. Another approach would be using break with labels.

In case you are using axios and trying via a service call.

URL: https://react-16-demo.firebaseio.com/
Schema Name: todos
Key: -Lhu8a0uoSRixdmECYPE

axios.delete(`https://react-16-demo.firebaseio.com/todos/-Lhu8a0uoSRixdmECYPE.json`). then();

can help.

 public void DeleteUserIMP(UserIMP useriamp) {
       synchronized (ListUserIMP) {
            if (ListUserIMP.isEmpty()) {
            System.out.println("user is empty");
        }  else {
            Iterator<UserIMP> it = ListUserIMP.iterator();
            while (it.hasNext()) {
                UserIMP user = it.next();
                if (useriamp.getMoblieNumber().equals(user.getMoblieNumber())) {
                    it.remove();
                    System.out.println("remove it");
                }
            }
            // ListUserIMP.remove(useriamp);

            System.out.println(" this user removed");
        }
        Constants.RESULT_FOR_REGISTRATION = Constants.MESSAGE_OK;
        // System.out.println("This user Deleted " + Constants.MESSAGE_OK);

    }
}

Using your example, you could do:

public void doit(A a) {
    if(a instanceof B) {
        // needs to cast to B to access draw2 which isn't present in A
        // note that this is probably not a good OO-design, but that would
        // be out-of-scope for this discussion :)
        ((B)a).draw2();
    }
    a.draw();
}

Though not POSIX, bash 4 has the &> operator:

command &> alloutput.txt

Use the FileSystemObject object, namely, its CreateFolder and CopyFile methods. Basically, this is what your script will look like:

Dim oFSO
Set oFSO = CreateObject("Scripting.FileSystemObject")

' Create a new folder
oFSO.CreateFolder "C:\MyFolder"

' Copy a file into the new folder
' Note that the destination folder path must end with a path separator (\)
oFSO.CopyFile "\\server\folder\file.ext", "C:\MyFolder\"

You may also want to add additional logic, like checking whether the folder you want to create already exists (because CreateFolder raises an error in this case) or specifying whether or not to overwrite the file being copied. So, you can end up with this:

Const strFolder = "C:\MyFolder\", strFile = "\\server\folder\file.ext"
Const Overwrite = True
Dim oFSO

Set oFSO = CreateObject("Scripting.FileSystemObject")

If Not oFSO.FolderExists(strFolder) Then
  oFSO.CreateFolder strFolder
End If

oFSO.CopyFile strFile, strFolder, Overwrite

Since I needed to analyze fat jars I was interested in the version of each individual class in a jar file. Therefore I took Joe Liversedge approach https://stackoverflow.com/a/27877215/1497139 and combined it with David J. Liszewski' https://stackoverflow.com/a/3313839/1497139 class number version table to create a bash script jarv to show the versions of all class files in a jar file.

Or if you want to be really specific [\w]{8}-[\w]{4}-[\w]{4}-[\w]{4}-[\w]{12}.

Use the CheckBoxList's GetItemChecked or GetItemCheckState method to find out whether an item is checked or not by its index.

I also faced this problem and fixed it by removing version part from the XSD name.

For others that find themselves here, the css I was looking for was

overflow-wrap: break-word;

Which will only break a word if it needs to (the length of the single word is greater than the width of the p), unlike word-break: break-all which can break the last word of every line.

In Sublime Text, after you select multiple regions of text, a click is considered a way to exit the multi-select mode. Move the cursor with the keyboard keys (arrows, Ctrl+arrows, etc.) instead, and you'll be fine

The Declarative model for Jenkins Pipelines has a restricted subset of syntax that it allows in the stage blocks - see the syntax guide for more info. You can bypass that restriction by wrapping your steps in a script { ... } block, but as a result, you'll lose validation of syntax, parameters, etc within the script block.

You can access the version through a URL, the web GUI, and the ReST API.

Via a URL

An HTML page displaying the version can be displayed in a browser at https://your-gitlab-url/help. The version is displayed only if you are signed in.

Via a menu in the web GUI

If you do not care to type this URL, you can also access the same HTML page from a menu in the GitLab web GUI:

In GitLab 11 and later

1. Log in to GitLab
2. Click on the drop down menu in the upper right. Select Help.
3. The GitLab version appears at the top of the page

In earlier versions, like GitLab 9

1. Log in to GitLab
2. Click on the drop down menu in the upper left. Select Help.
3. And then the version appears at the top of the page

Via the ReST API

Log in as any user, select the user icon in the upper right of the screen. Select Settings > Access Tokens. Create a personal access token and copy it to your clipboard.

In a Linux shell, use curl to access the GitLab version:

curl --header "PRIVATE-TOKEN: personal-access-token" your-gitlab-url/api/v4/version

DECLARE @StartDate datetime,@EndDate datetime

select @StartDate='3/2/2010', @EndDate='3/7/2010'

DECLARE @TotalDays INT,@WorkDays INT

DECLARE @ReducedDayswithEndDate INT

DECLARE @WeekPart INT

DECLARE @DatePart INT

SET @TotalDays= DATEDIFF(day, @StartDate, @EndDate) +1

SELECT @ReducedDayswithEndDate = CASE DATENAME(weekday, @EndDate)
    WHEN 'Saturday' THEN 1
    WHEN 'Sunday' THEN 2
    ELSE 0 END

SET @TotalDays=@TotalDays-@ReducedDayswithEndDate

SET @WeekPart=@TotalDays/7;

SET @DatePart=@TotalDays%7;

SET @WorkDays=(@WeekPart*5)+@DatePart

Check to see if your user is mapped to the DB you are trying to log into.

Try setting tableFooterView tableView.tableFooterView = UIView(frame: CGRect(x: 0, y: 0, width: 0, height: CGFloat.leastNonzeroMagnitude))

For my case, I had to pass DBNULL.Value(using if else condition) from code for stored procedures parameter that are not defined null but value is null.

$data = json_decode(...);
$firstId = $data[0]["id"];
$secondSeatNo = $data[1]["seat_no"];

Just like this :)

BigInteger.toString(radix) will do what you want. Just pass in a radix of 2.

static String hexToBin(String s) {
  return new BigInteger(s, 16).toString(2);
}

This sql script gives the schema, table name and row count of each table in a database selected:

SELECT SCHEMA_NAME(schema_id) AS [SchemaName],
[Tables].name AS [TableName],
SUM([Partitions].[rows]) AS [TotalRowCount]
FROM sys.tables AS [Tables]
JOIN sys.partitions AS [Partitions]
ON [Tables].[object_id] = [Partitions].[object_id]
AND [Partitions].index_id IN ( 0, 1 )
-- WHERE [Tables].name = N'name of the table'
GROUP BY SCHEMA_NAME(schema_id), [Tables].name
order by [TotalRowCount] desc

Ref: https://blog.sqlauthority.com/2017/05/24/sql-server-find-row-count-every-table-database-efficiently/

Another way of doing this:

SELECT  o.NAME TABLENAME,
  i.rowcnt 
FROM sysindexes AS i
  INNER JOIN sysobjects AS o ON i.id = o.id 
WHERE i.indid < 2  AND OBJECTPROPERTY(o.id, 'IsMSShipped') = 0
ORDER BY i.rowcnt desc

If you don't specify any path and put just the file (Just like you did), the default directory is always the one of your project (It's not inside the "src" folder. It's just inside the folder of your project).

Now a days phonegap and cordova is owned by Adobe. Only name conversation was different. For install plugin functionality , we should use same command for phonegap and cordova too.

Command : cordova plugin add cordova-plugin-photo-library

Here,

• cordova - keyword for initiator
• plugin - initialize a plugin
• cordova plugin photo library - plugin name.

You can also find more plugin from https://cordova.apache.org/docs/en/latest/

Some good answers here but just adding an approach that won't be affected by borders and padding:

<style type="text/css">
html, body{width: 100%; height: 100%; padding: 0; margin: 0}
div{position: absolute; padding: 1em; border: 1px solid #000}
#nw{background: #f09; top: 0; left: 0; right: 50%; bottom: 50%}
#ne{background: #f90; top: 0; left: 50%; right: 0; bottom: 50%}
#sw{background: #009; top: 50%; left: 0; right: 50%; bottom: 0}
#se{background: #090; top: 50%; left: 50%; right: 0; bottom: 0}
</style>

<div id="nw">test</div>
<div id="ne">test</div>
<div id="sw">test</div>
<div id="se">test</div>

Do not use the ToList() method as in the accepted answer !

Running SQL profiler, I verified and found that ToList() function gets all the records from the database. It is really bad performance !!

I would have run this query by pure sql command as follows:

string query = "Update YourTable Set ... Where ...";    
context.Database.ExecuteSqlCommandAsync(query, new SqlParameter("@ColumnY", value1), new SqlParameter("@ColumnZ", value2));

This would operate the update in one-shot without selecting even one row.

Your solution is correct, but there is some redundancy in your regex.
The similar result can also be obtained from the following regex:

^([A-Z]{3})$

The {3} indicates that the [A-Z] must appear exactly 3 times.

//Fields
String myID;
int myversion = 0;


myversion = Integer.valueOf(android.os.Build.VERSION.SDK);
if (myversion < 23) {
        TelephonyManager mngr = (TelephonyManager) 
getSystemService(Context.TELEPHONY_SERVICE);
        myID= mngr.getDeviceId();
    }
    else
    {
        myID = 
Settings.Secure.getString(getApplicationContext().getContentResolver(), 
Settings.Secure.ANDROID_ID);
    }

Yes, Secure.ANDROID_ID is unique for each device.

Your question as I understand it is divided in two parts, part one being you need a better understanding of the Naive Bayes classifier & part two being the confusion surrounding Training set.

In general all of Machine Learning Algorithms need to be trained for supervised learning tasks like classification, prediction etc. or for unsupervised learning tasks like clustering.

During the training step, the algorithms are taught with a particular input dataset (training set) so that later on we may test them for unknown inputs (which they have never seen before) for which they may classify or predict etc (in case of supervised learning) based on their learning. This is what most of the Machine Learning techniques like Neural Networks, SVM, Bayesian etc. are based upon.

So in a general Machine Learning project basically you have to divide your input set to a Development Set (Training Set + Dev-Test Set) & a Test Set (or Evaluation set). Remember your basic objective would be that your system learns and classifies new inputs which they have never seen before in either Dev set or test set.

The test set typically has the same format as the training set. However, it is very important that the test set be distinct from the training corpus: if we simply reused the training set as the test set, then a model that simply memorized its input, without learning how to generalize to new examples, would receive misleadingly high scores.

In general, for an example, 70% of our data can be used as training set cases. Also remember to partition the original set into the training and test sets randomly.

Now I come to your other question about Naive Bayes.

To demonstrate the concept of Naïve Bayes Classification, consider the example given below:

As indicated, the objects can be classified as either GREEN or RED. Our task is to classify new cases as they arrive, i.e., decide to which class label they belong, based on the currently existing objects.

Since there are twice as many GREEN objects as RED, it is reasonable to believe that a new case (which hasn't been observed yet) is twice as likely to have membership GREEN rather than RED. In the Bayesian analysis, this belief is known as the prior probability. Prior probabilities are based on previous experience, in this case the percentage of GREEN and RED objects, and often used to predict outcomes before they actually happen.

Thus, we can write:

Prior Probability of GREEN: number of GREEN objects / total number of objects

Prior Probability of RED: number of RED objects / total number of objects

Since there is a total of 60 objects, 40 of which are GREEN and 20 RED, our prior probabilities for class membership are:

Prior Probability for GREEN: 40 / 60

Prior Probability for RED: 20 / 60

Having formulated our prior probability, we are now ready to classify a new object (WHITE circle in the diagram below). Since the objects are well clustered, it is reasonable to assume that the more GREEN (or RED) objects in the vicinity of X, the more likely that the new cases belong to that particular color. To measure this likelihood, we draw a circle around X which encompasses a number (to be chosen a priori) of points irrespective of their class labels. Then we calculate the number of points in the circle belonging to each class label. From this we calculate the likelihood:

From the illustration above, it is clear that Likelihood of X given GREEN is smaller than Likelihood of X given RED, since the circle encompasses 1 GREEN object and 3 RED ones. Thus:

Although the prior probabilities indicate that X may belong to GREEN (given that there are twice as many GREEN compared to RED) the likelihood indicates otherwise; that the class membership of X is RED (given that there are more RED objects in the vicinity of X than GREEN). In the Bayesian analysis, the final classification is produced by combining both sources of information, i.e., the prior and the likelihood, to form a posterior probability using the so-called Bayes' rule (named after Rev. Thomas Bayes 1702-1761).

Finally, we classify X as RED since its class membership achieves the largest posterior probability.

Using itertools.chain:

import itertools
from collections import Iterable

def list_flatten(lst):
    flat_lst = []
    for item in itertools.chain(lst):
        if isinstance(item, Iterable):
            item = list_flatten(item)
            flat_lst.extend(item)
        else:
            flat_lst.append(item)
    return flat_lst

Or without chaining:

def flatten(q, final):
    if not q:
        return
    if isinstance(q, list):
        if not isinstance(q[0], list):
            final.append(q[0])
        else:
            flatten(q[0], final)
        flatten(q[1:], final)
    else:
        final.append(q)

If your code is dealing with XmlElements objects (rather than XmlNodes) then there is the method XmlElement.HasAttribute(string name).

So if you are only looking for attributes on elements (which it looks like from the OP) then it may be more robust to cast as an element, check for null, and then use the HasAttribute method.

foreach (XmlNode xNode in nodeListName)
{
  XmlElement xParentEle = xNode.ParentNode as XmlElement;
  if((xParentEle != null) && xParentEle.HasAttribute("split"))
  {
     parentSplit = xParentEle.Attributes["split"].Value;
  }
}

If you want Rails 3 or Ruby 1.9 compatibility try the date_validator gem.

In javascript there are no block-level scopes only function-level scopes:

Read this article about javaScript Scoping and Hoisting.

See how I debugged your code:

var deferred = $q.defer();
deferred.count = i;

console.log(deferred.count); // 0,1,2,3,4,5 --< all deferred objects

// some code

.success(function(data){
   console.log(deferred.count); // 5,5,5,5,5,5 --< only the last deferred object
   deferred.resolve(data);
})

• When you write var deferred= $q.defer(); inside a for loop it's hoisted to the top of the function, it means that javascript declares this variable on the function scope outside of the for loop.
• With each loop, the last deferred is overriding the previous one, there is no block-level scope to save a reference to that object.
• When asynchronous callbacks (success / error) are invoked, they reference only the last deferred object and only it gets resolved, so $q.all is never resolved because it still waits for other deferred objects.
• What you need is to create an anonymous function for each item you iterate.
• Since functions do have scopes, the reference to the deferred objects are preserved in a closure scope even after functions are executed.
• As #dfsq commented: There is no need to manually construct a new deferred object since $http itself returns a promise.

Solution with angular.forEach:

Here is a demo plunker: http://plnkr.co/edit/NGMp4ycmaCqVOmgohN53?p=preview

UploadService.uploadQuestion = function(questions){

    var promises = [];

    angular.forEach(questions , function(question) {

        var promise = $http({
            url   : 'upload/question',
            method: 'POST',
            data  : question
        });

        promises.push(promise);

    });

    return $q.all(promises);
}

My favorite way is to use Array#map:

Here is a demo plunker: http://plnkr.co/edit/KYeTWUyxJR4mlU77svw9?p=preview

UploadService.uploadQuestion = function(questions){

    var promises = questions.map(function(question) {

        return $http({
            url   : 'upload/question',
            method: 'POST',
            data  : question
        });

    });

    return $q.all(promises);
}

In the Windows command prompt you can disable tab completion, by launching it thusly:

cmd.exe /f:off

Then the tab character will be echoed to the screen and work as you expect. Or you can disable the tab completion character, or modify what character is used for tab completion by modifying the registry.

The cmd.exe help page explains it:

You can enable or disable file name completion for a particular invocation of CMD.EXE with the /F:ON or /F:OFF switch. You can enable or disable completion for all invocations of CMD.EXE on a machine and/or user logon session by setting either or both of the following REG_DWORD values in the registry using REGEDIT.EXE:

HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\CompletionChar
HKEY_LOCAL_MACHINE\Software\Microsoft\Command Processor\PathCompletionChar

    and/or

HKEY_CURRENT_USER\Software\Microsoft\Command Processor\CompletionChar
HKEY_CURRENT_USER\Software\Microsoft\Command Processor\PathCompletionChar

with the hex value of a control character to use for a particular function (e.g. 0x4 is Ctrl-D and 0x6 is Ctrl-F). The user specific settings take precedence over the machine settings. The command line switches take precedence over the registry settings.

If completion is enabled with the /F:ON switch, the two control characters used are Ctrl-D for directory name completion and Ctrl-F for file name completion. To disable a particular completion character in the registry, use the value for space (0x20) as it is not a valid control character.

The only good solution to this problem can be found in the gulp documentation:

var gulp = require('gulp');

// takes in a callback so the engine knows when it'll be done
gulp.task('one', function(cb) {
  // do stuff -- async or otherwise
  cb(err); // if err is not null and not undefined, the orchestration will stop, and 'two' will not run
});

// identifies a dependent task must be complete before this one begins
gulp.task('two', ['one'], function() {
  // task 'one' is done now
});

gulp.task('default', ['one', 'two']);
// alternatively: gulp.task('default', ['two']);

In my experience it may be the result of auto-generation by a string-based tools, where the author did not understand the rules of HTML.

When some developers generate HTML without the use of special XML-oriented tools, they may try to be sure the resulting HTML is valid by taking the approach that everything must be escaped.

Referring to your example, the reason why every occurrence of " is represented by " could be because using that approach, you can safely use such "special" characters in both attributes and values.

Another motivation I've seen is where people believe, "We must explicitly show that our symbols are not part of the syntax." Whereas, valid HTML can be created by using the proper string-manipulation tools, see the previous paragraph again.

Here is some pseudo-code loosely based on C#, although it is preferred to use valid methods and tools:

public class HtmlAndXmlWriter
{
    private string Escape(string badString)
    {
        return badString.Replace("&", "&amp;").Replace("\"", "&quot;").Replace("'", "&apos;").Replace(">", "&gt;").Replace("<", "&lt;");

    }

    public string GetHtmlFromOutObject(Object obj)
    {
        return "<div class='type_" + Escape(obj.Type) + "'>" + Escape(obj.Value) + "</div>";    

    }

}

It's really very common to see such approaches taken to generate HTML.

First a link to some documentation of fork()

http://pubs.opengroup.org/onlinepubs/009695399/functions/fork.html

The pid is provided by the kernel. Every time the kernel create a new process it will increase the internal pid counter and assign the new process this new unique pid and also make sure there are no duplicates. Once the pid reaches some high number it will wrap and start over again.

So you never know what pid you will get from fork(), only that the parent will keep it's unique pid and that fork will make sure that the child process will have a new unique pid. This is stated in the documentation provided above.

If you continue reading the documentation you will see that fork() return 0 for the child process and the new unique pid of the child will be returned to the parent. If the child want to know it's own new pid you will have to query for it using getpid().

pid_t pid = fork()
if(pid == 0) {
    printf("this is a child: my new unique pid is %d\n", getpid());
} else {
    printf("this is the parent: my pid is %d and I have a child with pid %d \n", getpid(), pid);
}

and below is some inline comments on your code

#include <stdio.h>
#include <sys/types.h>
#include <unistd.h>

int main() {
    pid_t pid1, pid2, pid3;
    pid1=0, pid2=0, pid3=0;
    pid1= fork(); /* A */
    if(pid1 == 0){
        /* This is child A */
        pid2=fork(); /* B */
        pid3=fork(); /* C */
    } else {
        /* This is parent A */
        /* Child B and C will never reach this code */
        pid3=fork(); /* D */
        if(pid3==0) {
            /* This is child D fork'ed from parent A */
            pid2=fork(); /* E */
        }
        if((pid1 == 0)&&(pid2 == 0)) {
            /* pid1 will never be 0 here so this is dead code */
            printf("Level 1\n");
        }
        if(pid1 !=0) {
            /* This is always true for both parent and child E */
            printf("Level 2\n");
        }
        if(pid2 !=0) {
           /* This is parent E (same as parent A) */
           printf("Level 3\n");
        }
        if(pid3 !=0) {
           /* This is parent D (same as parent A) */
           printf("Level 4\n");
        }
    }
    return 0;
}

You can use a regular expression to delete white spaces , try that snippet:

Scanner scan = new Scanner(System.in);
    System.out.println(scan.nextLine().replaceAll(" ", ""));

If you really must use jQuery to solve this problem (NB: you shouldn't):

(function($) {
    $.rand = function(arg) {
        if ($.isArray(arg)) {
            return arg[$.rand(arg.length)];
        } else if (typeof arg === "number") {
            return Math.floor(Math.random() * arg);
        } else {
            return 4;  // chosen by fair dice roll
        }
    };
})(jQuery);

var items = [523, 3452, 334, 31, ..., 5346];
var item = jQuery.rand(items);

This plugin will return a random element if given an array, or a value from [0 .. n) given a number, or given anything else, a guaranteed random value!

For extra fun, the array return is generated by calling the function recursively based on the array's length :)

Some answers seem just wrong,

1. you can't use dictionary how would store the pairs (a,b) and (a,c). Pairs concept should not be confused with associative look up of key and values
2. lot of the above code seems suspect

Here is my pair class

public class Pair<X, Y>
{
    private X _x;
    private Y _y;

    public Pair(X first, Y second)
    {
        _x = first;
        _y = second;
    }

    public X first { get { return _x; } }

    public Y second { get { return _y; } }

    public override bool Equals(object obj)
    {
        if (obj == null)
            return false;
        if (obj == this)
            return true;
        Pair<X, Y> other = obj as Pair<X, Y>;
        if (other == null)
            return false;

        return
            (((first == null) && (other.first == null))
                || ((first != null) && first.Equals(other.first)))
              &&
            (((second == null) && (other.second == null))
                || ((second != null) && second.Equals(other.second)));
    }

    public override int GetHashCode()
    {
        int hashcode = 0;
        if (first != null)
            hashcode += first.GetHashCode();
        if (second != null)
            hashcode += second.GetHashCode();

        return hashcode;
    }
}

Here is some test code:

[TestClass]
public class PairTest
{
    [TestMethod]
    public void pairTest()
    {
        string s = "abc";
        Pair<int, string> foo = new Pair<int, string>(10, s);
        Pair<int, string> bar = new Pair<int, string>(10, s);
        Pair<int, string> qux = new Pair<int, string>(20, s);
        Pair<int, int> aaa = new Pair<int, int>(10, 20);

        Assert.IsTrue(10 == foo.first);
        Assert.AreEqual(s, foo.second);
        Assert.AreEqual(foo, bar);
        Assert.IsTrue(foo.GetHashCode() == bar.GetHashCode());
        Assert.IsFalse(foo.Equals(qux));
        Assert.IsFalse(foo.Equals(null));
        Assert.IsFalse(foo.Equals(aaa));

        Pair<string, string> s1 = new Pair<string, string>("a", "b");
        Pair<string, string> s2 = new Pair<string, string>(null, "b");
        Pair<string, string> s3 = new Pair<string, string>("a", null);
        Pair<string, string> s4 = new Pair<string, string>(null, null);
        Assert.IsFalse(s1.Equals(s2));
        Assert.IsFalse(s1.Equals(s3));
        Assert.IsFalse(s1.Equals(s4));
        Assert.IsFalse(s2.Equals(s1));
        Assert.IsFalse(s3.Equals(s1));
        Assert.IsFalse(s2.Equals(s3));
        Assert.IsFalse(s4.Equals(s1));
        Assert.IsFalse(s1.Equals(s4));
    }
}

I know its a long time since Jon's original answer, but I had a similar requirement to the OP.

By way of extending Jon's solution I came up with the following, which will take one or more path segments takes as many path segments that you can throw at it.

Usage

Path.combine("/Users/beardtwizzle/");
Path.combine("/", "Users", "beardtwizzle");
Path.combine(new String[] { "/", "Users", "beardtwizzle", "arrayUsage" });

Code here for others with a similar problem

public class Path {
    public static String combine(String... paths)
    {
        File file = new File(paths[0]);

        for (int i = 1; i < paths.length ; i++) {
            file = new File(file, paths[i]);
        }

        return file.getPath();
    }
}

Just to offer an update to the answer for people with API min 19, per the docs:

On Android 4.4 (API level 19) and higher, you have the additional option of using the ACTION_OPEN_DOCUMENT intent, which displays a system-controlled picker UI controlled that allows the user to browse all files that other apps have made available. From this single UI, the user can pick a file from any of the supported apps.

On Android 5.0 (API level 21) and higher, you can also use the ACTION_OPEN_DOCUMENT_TREE intent, which allows the user to choose a directory for a client app to access.

Open files using storage access framework - Android Docs

     val intent = Intent(Intent.ACTION_OPEN_DOCUMENT)
     intent.type = "image/*"
     startActivityForResult(intent, PICK_IMAGE_REQUEST_CODE)

Platform-dependent, toolchain-dependent, ulimit-dependent, parameter-dependent.... It is not at all specified, and there are many static and dynamic properties that can influence it.

<div className='btn' onClick={(e) =>
     console.log(e.currentTarget.attributes['tag'].value)}
     tag='bold'>
    <i className='fa fa-bold' />
</div>

so e.currentTarget.attributes['tag'].value works for me

As Christian's answer with assign() shows, there is a way to assign in the global environment. A simpler, shorter (but not better ... stick with assign) way is to use the <<- operator, ie

    a <<- "new" 

inside the function.

If you use .Net 4.5 you can also use standard .Net json serializer:

using System.Runtime.Serialization.Json;
...    
Stream jsonSource = ...; // serializer will read data stream
var s = new DataContractJsonSerializer(typeof(string[][]));
var j = (string[][])s.ReadObject(jsonSource);

In .Net 4.5 and older you can use JavaScriptSerializer class:

using System.Web.Script.Serialization;
...
JavaScriptSerializer serializer = new JavaScriptSerializer();
string[][] list = serializer.Deserialize<string[][]>(json);

Add this line before main function:

void swapCase (char* name);

int main()
{
   ...
   swapCase(name);    // swapCase prototype should be known at this point
   ...
}

This is called forward declaration: compiler needs to know function prototype when function call is compiled.

For ubuntu 14.04LTS with php 7, issue:

sudo apt-get install php-dev

Then install:

pecl install memcache

List comprehensions are eager but generators are lazy.

In list comprehensions all objects are created right away, it takes longer to create and return the list. In generator expressions, object creation is delayed until request by next(). Upon next() generator object is created and returned immediately.

Iteration is faster in list comprehensions because objects are already created.

If you iterate all the elements in list comprehension and generator expression, time performance is about the same. Even though generator expression return generator object right away, it does not create all the elements. Everytime you iterate over a new element, it will create and return it.

But if you do not iterate through all the elements generator are more efficient. Let's say you need to create a list comprehensions that contains millions of items but you are using only 10 of them. You still have to create millions of items. You are just wasting time for making millions of calculations to create millions of items to use only 10. Or if you are making millions of api requests but end up using only 10 of them. Since generator expressions are lazy, it does not make all the calculations or api calls unless it is requested. In this case using generator expressions will be more efficient.

In list comprehensions entire collection is loaded to the memory. But generator expressions, once it returns a value to you upon your next() call, it is done with it and it does not need to store it in the memory any more. Only a single item is loaded to the memory. If you are iterating over a huge file in disk, if file is too big you might get memory issue. In this case using generator expression is more efficient.

Given its name, I think the standard way should be delete:

import numpy as np

A = np.delete(A, 1, 0)  # delete second row of A
B = np.delete(B, 2, 0)  # delete third row of B
C = np.delete(C, 1, 1)  # delete second column of C

According to numpy's documentation page, the parameters for numpy.delete are as follow:

numpy.delete(arr, obj, axis=None)

• arr refers to the input array,
• obj refers to which sub-arrays (e.g. column/row no. or slice of the array) and
• axis refers to either column wise (axis = 1) or row-wise (axis = 0) delete operation.

The accepted answer works perfectly fine. I just want to mention a minor problem with the answer devXen has given.

If you set the icon like this:

<link rel="shortcut icon" type="image/x-icon" href="icon.ico">

The icon will work as expected:

However, if you set it like devXen has suggested:

<title> Amir A. Shabani</title>

The title of the page moves upon refresh:

So I would advise using <link> instead.

You can't select a sheet in a non-active workbook.

You must first activate the workbook, then you can select the sheet.

workbooks("A").activate
workbooks("A").worksheets("B").select 

When you use Activate it automatically activates the workbook.

Note you can select >1 sheet in a workbook:

activeworkbook.sheets(array("sheet1","sheet3")).select

but only one sheet can be Active, and if you activate a sheet which is not part of a multi-sheet selection then those other sheets will become un-selected.

If you have created the migrations, you could execute them in the Startup.cs as follows.

 public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
 {
      using (var serviceScope = app.ApplicationServices.GetService<IServiceScopeFactory>().CreateScope())
      {
            var context = serviceScope.ServiceProvider.GetRequiredService<ApplicationDbContext>();
            context.Database.Migrate();
      }
      
      ...

This will create the database and the tables using your added migrations.

If you're not using Entity Framework Migrations, and instead just need your DbContext model created exactly as it is in your context class at first run, then you can use:

 public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
 {
      using (var serviceScope = app.ApplicationServices.GetService<IServiceScopeFactory>().CreateScope())
      {
            var context = serviceScope.ServiceProvider.GetRequiredService<ApplicationDbContext>();
            context.Database.EnsureCreated();
      }
      
      ...

Instead.

If you need to delete your database prior to making sure it's created, call:

            context.Database.EnsureDeleted();

Just before you call EnsureCreated()

Call decode() on a bytes instance to get the text which it encodes.

str = bytes.decode()

It depends on what kind of markdown parser you're using. For example in showdownjs there is an option {simpleLineBreaks: true} which gives corresponding html for the following md input:

a line

From Oracle documentation page on ScheduledThreadPoolExecutor

A ThreadPoolExecutor that can additionally schedule commands to run after a given delay, or to execute periodically. This class is preferable to Timer when multiple worker threads are needed, or when the additional flexibility or capabilities of ThreadPoolExecutor (which this class extends) are required.

ExecutorService/ThreadPoolExecutor or ScheduledThreadPoolExecutor is obvious choice when you have multiple worker threads.

Pros of ExecutorService over Timer

1. Timer can't take advantage of available CPU cores unlike ExecutorService especially with multiple tasks using flavours of ExecutorService like ForkJoinPool
2. ExecutorService provides collaborative API if you need coordination between multiple tasks. Assume that you have to submit N number of worker tasks and wait for completion of all of them. You can easily achieve it with invokeAll API. If you want to achieve the same with multiple Timer tasks, it would be not simple.

3. ThreadPoolExecutor provides better API for management of Thread life cycle.

   Thread pools address two different problems: they usually provide improved performance when executing large numbers of asynchronous tasks, due to reduced per-task invocation overhead, and they provide a means of bounding and managing the resources, including threads, consumed when executing a collection of tasks. Each ThreadPoolExecutor also maintains some basic statistics, such as the number of completed tasks

   Few advantages:

   a. You can create/manage/control life cycle of Threads & optimize thread creation cost overheads

   b. You can control processing of tasks ( Work Stealing, ForkJoinPool, invokeAll) etc.

   c. You can monitor the progress and health of threads

   d. Provides better exception handling mechanism

If you know this when the page is rendered, which it sounds like you do because the database has a value, it's better to disable it when rendered instead of JavaScript. To do that, just add the readonly attribute (or disabled, if you want to remove it from the form submission as well) to the <input>, like this:

<input type="text" disabled="disabled" />
//or...
<input type="text" readonly="readonly" />

2017-05 update:

I just found that if you add the following line into your vimrc file,

set clipboard=unnamed

then Vim is using the system clipboard.

I just found the yank way won't work on the way where I copy contents between different Vim instance windows. (At least, it doesn't work based on my Vim knowledge. I don't know if there is another way to enable it to work).

The yank way only works on the way where multiple files are opened in the same window according to my test.

If you want to do that, you'd better use OS cut-copy-past way such as Ctrl + x, Ctrl + c (under Windows).

There is only one easy solution, that you can remember and implement wherever needed. No bugs, no crazy calculations. Put margin to the card / item layout and put the same size as padding to the RecyclerView:

item_layout.xml

<CardView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:margin="10dp">

activity_layout.xml

<RecyclerView
    android:layout_width="match_parent"
    android:layout_height="wrap_content"
    android:padding="10dp"/>

UPDATE:

A slight extension to the answer given, so, hopefully useful to the asker and anyone else looking.

You can also SELECT the values you want to delete. But watch out for the Error 1093 - You can't specify the target table for update in FROM clause.

DELETE FROM
    orders_products_history
WHERE
    (branchID, action) IN (
    SELECT
        branchID,
        action
    FROM
        (
        SELECT
            branchID,
            action
        FROM
            orders_products_history
        GROUP BY
            branchID,
            action
        HAVING
            COUNT(*) > 10000
        ) a
    );

I wanted to delete all history records where the number of history records for a single action/branch exceed 10,000. And thanks to this question and chosen answer, I can.

Hope this is of use.

Richard.

I had a problem with a big delay between calling setNeedsDisplay and drawRect: (5 seconds). It turned out I called setNeedsDisplay in a different thread than the main thread. After moving this call to the main thread the delay went away.

Hope this is of some help.

No. It's not possible.

Example:

import random

def gen(n):
    for i in xrange(n):
        if random.randint(0, 1) == 0:
            yield i

iterator = gen(10)

Length of iterator is unknown until you iterate through it.

You need to create own PCH file
Add New file -> Other-> PCH file

Then add the path of this PCH file to your build setting->prefix header->path

($(SRCROOT)/filename.pch)

Since Unity 4.3 you also have to enable External option from preferences, so full setup process looks like:

1. Enable External option in Unity ? Preferences ? Packages ? Repository
2. Switch to Hidden Meta Files in Editor ? Project Settings ? Editor ? Version Control Mode
3. Switch to Force Text in Editor ? Project Settings ? Editor ? Asset Serialization Mode
4. Save scene and project from File menu

Note that the only folders you need to keep under source control are Assets and ProjectSettigns.

More information about keeping Unity Project under source control you can find in this post.

Have posted the same answer in two other similar questions. The way I prefer to do this is to wrap up the return values of the function in a series:

def f(x):
    return pd.Series([x**2, x**3])

And then use apply as follows to create separate columns:

df[['x**2','x**3']] = df.apply(lambda row: f(row['x']), axis=1)

Try putting the height into one of the cells, like this:

<table class="tableContainer" cellspacing="10px">
 <tr>
  <td style="height:15px;">NHS Number</td>
  <td>&#160;</td>

Note however, that you won't be able to make the cell smaller than the content requires it to be. In that case you would have to make the text smaller first.

I guess this thread needs an update. If you look at any of the npm registries which are available, they are extremely heavy and they need couchdb. Gemfurry and others need you to fork off from public repos. Some of the npm's like shadow-npm have no recent commits.

Then, we found Reggie. Its got a good commit activity, extremely easy to install and use and has pretty good community support. Its extremely light-weight and you don't have to deal with couchdb, etc.

CDATA stands for Character Data. You can use this to escape some characters which otherwise will be treated as regular XML. The data inside this will not be parsed. For example, if you want to pass a URL that contains & in it, you can use CDATA to do it. Otherwise, you will get an error as it will be parsed as regular XML.

See also: How to properly override clone method?. Cloning is broken in Java, it's so hard to get it right, and even when it does it doesn't really offer much, so it's not really worth the hassle.

Making a class abstract sends a message to the readers of your code that you want users of your abstract class to subclass it. However, this is not what you want then to do: a utility class should not be subclassed.

Therefore, adding a private constructor is a better choice here. You should also make the class final to disallow subclassing of your utility class.

The functionality is already present in atom via the Symbols View package you don't need to install anything.

The command you are searching for is symbols-view:go-to-declaration (Jump to the symbol under the cursor) which is bound by default to cmd-alt-down on macOS and ctrl-alt-down on Linux.

just note that it will work only if you will have generated tags for your project, either via this package or via ctags (exuberant or not)

use jquery

$("#item").change(function({
    var x=$(this).val();
});

Your value will be in x variable, use this variable value in your jsp, like this {x} this statement will give the value

Looking at the jQuery code, this is what happens:

hide: function( speed, easing, callback ) {
    if ( speed || speed === 0 ) {
        return this.animate( genFx("hide", 3), speed, easing, callback);

    } else {
        for ( var i = 0, j = this.length; i < j; i++ ) {
            var display = jQuery.css( this[i], "display" );

            if ( display !== "none" ) {
                jQuery.data( this[i], "olddisplay", display );
            }
        }

        // Set the display of the elements in a second loop
        // to avoid the constant reflow
        for ( i = 0; i < j; i++ ) {
            this[i].style.display = "none";
        }

        return this;
    }
},

First open your SSH server with username and password and change to the default root user(User with all permissions) then follow the steps below,

1. enter the command crontab -l now you will see the list of all cronjobs.
2. enter crontab -e a file with all cron jobs will be opened.
3. Edit the file with your cronjob schedule as min hr dayofmonth month dayofweek pathtocronjobfile and save the file.
4. Now you will see a response crontab: installing new crontab now again check the list of cronjobs your cron job will be listed there.

You need the @Value annotation.

A common use case is to assign default field values using "#{systemProperties.myProp}" style expressions.

public class SimpleMovieLister {

  private MovieFinder movieFinder;
  private String defaultLocale;

  @Autowired
  public void configure(MovieFinder movieFinder, 
                        @Value("#{ systemProperties['user.region'] }") String defaultLocale) {
      this.movieFinder = movieFinder;
      this.defaultLocale = defaultLocale;
  }

  // ...
}

See: Expression Language > Annotation Configuration

To be more clear: in your scenario, you'd wire two classes, MybeanService and MyConstructorClass, something like this:

@Component
public class MyBeanService implements BeanService{
    @Autowired
    public MybeanService(MyConstructorClass foo){
        // do something with foo
    }
}

@Component
public class MyConstructorClass{
    public MyConstructorClass(@Value("#{some expression here}") String value){
         // do something with value
    }
}

Update: if you need several different instances of MyConstructorClass with different values, you should use Qualifier annotations

This was so annoying. Open your project, click on Target, Open Build Phases tab. Check your Copy Bundle Resources for any red items.

Here is a simple example, it will help you to get object key name.

var obj ={parts:{costPart:1000, salesPart: 2000}}; console.log(Object.keys(obj));

the output would be parts.
