You can add any Git repository (or tarball) as a dependency to yarn by specifying the remote URL (either HTTPS or SSH):

yarn add <git remote url> installs a package from a remote git repository.
yarn add <git remote url>#<branch/commit/tag> installs a package from a remote git repository at specific git branch, git commit or git tag.
yarn add https://my-project.org/package.tgz installs a package from a remote gzipped tarball.

Here are some examples:

yarn add https://github.com/fancyapps/fancybox [remote url]
yarn add ssh://github.com/fancyapps/fancybox#3.0  [branch]
yarn add https://github.com/fancyapps/fancybox#5cda5b529ce3fb6c167a55d42ee5a316e921d95f [commit]

(Note: Fancybox v2.6.1 isn't available in the Git version.)

To support both npm and yarn, you can use the git+url syntax:

git+https://github.com/owner/package.git#commithashortagorbranch
git+ssh://github.com/owner/package.git#commithashortagorbranch

System.out.print("Enter a Value: ");
val = s.nextInt();

This line is placed in last.The whole code is as follows:-

public static void main(String[] args){
    int min, max;

    Scanner s = new Scanner(System.in);
    System.out.print("Enter a Value: ");
    int val = s.nextInt();
    min = max = val;

    while (val != 0) {
        if (val < min) {
            min = val;
        }
        if (val > max) {
            max = val;
        }
        System.out.print("Enter a Value: ");
        val = s.nextInt();

    }
    System.out.println("Min: " + min);
    System.out.println("Max: " + max);
}

Use Math.Round

int d = (int) Math.Round(a, 0);

Statically typed languages: each variable and expression is already known at compile time.

(int a; a can take only integer type values at runtime)

Examples: C, C++, Java

Dynamically typed languages: variables can receive different values at runtime and their type is defined at run time.

(var a; a can take any kind of values at runtime)

Examples: Ruby, Python.

I use thisone, it's only Javascript.

I simply have an input element with a value, and when the user clicks on the input element, it changes it to an input element without a value.

You can easily change the color of the text using CSS. The color of the placeholder is the color in the id #IEinput, and the color your typed text will be is the color in the id #email. Don't use getElementsByClassName, because the versions of IE that don't support a placeholder, don't support getElementsByClassName either!

You can use a placeholder in a password input by setting the type of the original password input to text.

I used :

instead of

from PIL import Image

and it worked for me fine

wish you bests

No, the methods don't need to be synchronized, and you don't need to define any methods; they are already in ConcurrentLinkedQueue, just use them. ConcurrentLinkedQueue does all the locking and other operations you need internally; your producer(s) adds data into the queue, and your consumers poll for it.

First, create your queue:

Queue<YourObject> queue = new ConcurrentLinkedQueue<YourObject>();

Now, wherever you are creating your producer/consumer objects, pass in the queue so they have somewhere to put their objects (you could use a setter for this, instead, but I prefer to do this kind of thing in a constructor):

YourProducer producer = new YourProducer(queue);

and:

YourConsumer consumer = new YourConsumer(queue);

and add stuff to it in your producer:

queue.offer(myObject);

and take stuff out in your consumer (if the queue is empty, poll() will return null, so check it):

YourObject myObject = queue.poll();

For more info see the Javadoc

EDIT:

If you need to block waiting for the queue to not be empty, you probably want to use a LinkedBlockingQueue, and use the take() method. However, LinkedBlockingQueue has a maximum capacity (defaults to Integer.MAX_VALUE, which is over two billion) and thus may or may not be appropriate depending on your circumstances.

If you only have one thread putting stuff into the queue, and another thread taking stuff out of the queue, ConcurrentLinkedQueue is probably overkill. It's more for when you may have hundreds or even thousands of threads accessing the queue at the same time. Your needs will probably be met by using:

Queue<YourObject> queue = Collections.synchronizedList(new LinkedList<YourObject>());

A plus of this is that it locks on the instance (queue), so you can synchronize on queue to ensure atomicity of composite operations (as explained by Jared). You CANNOT do this with a ConcurrentLinkedQueue, as all operations are done WITHOUT locking on the instance (using java.util.concurrent.atomic variables). You will NOT need to do this if you want to block while the queue is empty, because poll() will simply return null while the queue is empty, and poll() is atomic. Check to see if poll() returns null. If it does, wait(), then try again. No need to lock.

Finally:

Honestly, I'd just use a LinkedBlockingQueue. It is still overkill for your application, but odds are it will work fine. If it isn't performant enough (PROFILE!), you can always try something else, and it means you don't have to deal with ANY synchronized stuff:

BlockingQueue<YourObject> queue = new LinkedBlockingQueue<YourObject>();

queue.put(myObject); // Blocks until queue isn't full.

YourObject myObject = queue.take(); // Blocks until queue isn't empty.

Everything else is the same. Put probably won't block, because you aren't likely to put two billion objects into the queue.

If you are on SQL Server 2008 or later version, you can use the ROLLUP() GROUP BY function:

SELECT
  Type = ISNULL(Type, 'Total'),
  TotalSales = SUM(TotalSales)
FROM atable
GROUP BY ROLLUP(Type)
;

This assumes that the Type column cannot have NULLs and so the NULL in this query would indicate the rollup row, the one with the grand total. However, if the Type column can have NULLs of its own, the more proper type of accounting for the total row would be like in @Declan_K's answer, i.e. using the GROUPING() function:

SELECT
  Type = CASE GROUPING(Type) WHEN 1 THEN 'Total' ELSE Type END,
  TotalSales = SUM(TotalSales)
FROM atable
GROUP BY ROLLUP(Type)
;

QT provides this with OS abstraction as QCoreApplication::applicationDirPath()

just do something like this:

        ListIterator<String> it = list1.listIterator();
        int index = -1;
        while (it.hasNext()) {
            index++;
            String value = it.next();
            //At this point the index can be checked for the current element.

        }

In jQuery just use:

$('#tblOne > tbody  > tr').each(function() {...code...});

Using the children selector (>) you will walk over all the children (and not all descendents), example with three rows:

$('table > tbody  > tr').each(function(index, tr) { 
   console.log(index);
   console.log(tr);
});

Result:

0
<tr>
1 
<tr>
2
<tr>

In VanillaJS you can use document.querySelectorAll() and walk over the rows using forEach()

[].forEach.call(document.querySelectorAll('#tblOne > tbody  > tr'), function(index, tr) {
    /* console.log(index); */
    /* console.log(tr); */
});

In my case the only way I could keep using GetGroups() without any expcetion was adding the user (USER_WITH_PERMISSION) to the group which has permission to read the AD (Active Directory). It's extremely essential to construct the PrincipalContext passing this user and password.

var pc = new PrincipalContext(ContextType.Domain, domain, "USER_WITH_PERMISSION", "PASS");
var user = UserPrincipal.FindByIdentity(pc, IdentityType.SamAccountName, userName);
var groups = user.GetGroups();

Steps you may follow inside Active Directory to get it working:

1. Into Active Directory create a group (or take one) and under secutiry tab add "Windows Authorization Access Group"
2. Click on "Advanced" button
3. Select "Windows Authorization Access Group" and click on "View"
4. Check "Read tokenGroupsGlobalAndUniversal"
5. Locate the desired user and add to the group you created (taken) from the first step

I used this method.

Looper.myLooper().quit();

you can try.

Upload image with form data using NSURLConnection class in Swift 2.2:

    func uploadImage(){
        let imageData = UIImagePNGRepresentation(UIImage(named: "dexter.jpg")!)

        if imageData != nil{
            let str = "https://staging.mywebsite.com/V2.9/uploadfile"
            let request = NSMutableURLRequest(URL: NSURL(string:str)!)
            request.HTTPMethod = "POST"

            let boundary = NSString(format: "---------------------------14737809831466499882746641449")

            let contentType = NSString(format: "multipart/form-data; boundary=%@",boundary)
            request.addValue(contentType as String, forHTTPHeaderField: "Content-Type")

            let body = NSMutableData()

            // append image data to body
            body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!)
            body.appendData(NSString(format:"Content-Disposition: form-data; name=\"file\"; filename=\"img.jpg\"\\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
            body.appendData(NSString(format: "Content-Type: application/octet-stream\r\n\r\n").dataUsingEncoding(NSUTF8StringEncoding)!)
            body.appendData(imageData!)
            body.appendData(NSString(format: "\r\n--%@\r\n", boundary).dataUsingEncoding(NSUTF8StringEncoding)!)

            request.HTTPBody = body

            do {
                let returnData = try NSURLConnection.sendSynchronousRequest(request, returningResponse: nil)
                let returnString = NSString(data: returnData, encoding: NSUTF8StringEncoding)
                print("returnString = \(returnString!)")
            }
            catch let  error as NSError {
                print(error.description)
            }
        }
    }

Note: Always use sendAsynchronousRequest method instead of sendSynchronousRequest for uploading/downloading data to avoid blocking main thread. Here I used sendSynchronousRequest for testing purpose only.

I think what you're of doing here is using a structure containing your class instances. I don't know the syntax for naming structures in python, but in perl I could create a structure obj.id[x] where x is an incremented integer. Then, I could just refer back to the specific class instance I needed by referencing the struct numerically. Is this anything in the direction of what you're trying to do?

The accepted answer previously contained new Buffer(), which is considered a security issue in node versions greater than 6 (although it seems likely for this usecase that the input can always be coerced to a string).

The Buffer constructor is deprecated according to the documentation.

Here is an example of a vulnerability that can result from using it in the ws library.

The code snippets should read:

console.log(Buffer.from("Hello World").toString('base64'));
console.log(Buffer.from("SGVsbG8gV29ybGQ=", 'base64').toString('ascii'));

After this answer was written, it has been updated and now matches this.

I got the same error when the script file I was including container some special characters and when I was running in local moode (directly from local disk). I my case the solution was to explicitly tell the encoding:

<script src="my.js" charset="UTF-8"></script>

How to get the height of the navigation bar and status bar. This code works for me on some Huawei devices and Samsung devices. Egis's solution above is good, however, it is still incorrect on some devices. So, I improved it.

This is code to get the height of status bar

private fun getStatusBarHeight(resources: Resources): Int {
        var result = 0
        val resourceId = resources.getIdentifier("status_bar_height", "dimen", "android")
        if (resourceId > 0) {
            result = resources.getDimensionPixelSize(resourceId)
        }
        return result
    }

This method always returns the height of navigation bar even when the navigation bar is hidden.

private fun getNavigationBarHeight(resources: Resources): Int {
    val resourceId = resources.getIdentifier("navigation_bar_height", "dimen", "android")
    return if (resourceId > 0) {
        resources.getDimensionPixelSize(resourceId)
    } else 0
}

NOTE: on Samsung A70, this method returns the height of the status bar + height of the navigation bar. On other devices (Huawei), it only returns the height of the Navigation bar and returns 0 when the navigation bar is hidden.

private fun getNavigationBarHeight(): Int {
        val display = activity?.windowManager?.defaultDisplay
        return if (display == null) {
            0
        } else {
            val realMetrics = DisplayMetrics()
            display.getRealMetrics(realMetrics)
            val metrics = DisplayMetrics()
            display.getMetrics(metrics)
            realMetrics.heightPixels - metrics.heightPixels
        }
    }

This is code to get height of navigation bar and status bar

val metrics = DisplayMetrics()
        activity?.windowManager?.defaultDisplay?.getRealMetrics(metrics)

        //resources is got from activity

        //NOTE: on SamSung A70, this height = height of status bar + height of Navigation bar
        //On other devices (Huawei), this height = height of Navigation bar
        val navigationBarHeightOrNavigationBarPlusStatusBarHeight = getNavigationBarHeight()

        val statusBarHeight = getStatusBarHeight(resources)
        //The method will always return the height of navigation bar even when the navigation bar was hidden.
        val realNavigationBarHeight = getNavigationBarHeight(resources)

        val realHeightOfStatusBarAndNavigationBar =
                if (navigationBarHeightOrNavigationBarPlusStatusBarHeight == 0 || navigationBarHeightOrNavigationBarPlusStatusBarHeight < statusBarHeight) {
                    //Huawei: navigation bar is hidden
                    statusBarHeight
                } else if (navigationBarHeightOrNavigationBarPlusStatusBarHeight == realNavigationBarHeight) {
                    //Huawei: navigation bar is visible
                    statusBarHeight + realNavigationBarHeight
                } else if (navigationBarHeightOrNavigationBarPlusStatusBarHeight < realNavigationBarHeight) {
                    //SamSung A70: navigation bar is still visible but it only displays as a under line
                    //navigationBarHeightOrNavigationBarPlusStatusBarHeight = navigationBarHeight'(under line) + statusBarHeight
                    navigationBarHeightOrNavigationBarPlusStatusBarHeight
                } else {
                    //SamSung A70: navigation bar is visible
                    //navigationBarHeightOrNavigationBarPlusStatusBarHeight == statusBarHeight + realNavigationBarHeight
                    navigationBarHeightOrNavigationBarPlusStatusBarHeight
                }

You need to pass in a sequence, but you forgot the comma to make your parameters a tuple:

cursor.execute('INSERT INTO images VALUES(?)', (img,))

Without the comma, (img) is just a grouped expression, not a tuple, and thus the img string is treated as the input sequence. If that string is 74 characters long, then Python sees that as 74 separate bind values, each one character long.

>>> len(img)
74
>>> len((img,))
1

If you find it easier to read, you can also use a list literal:

cursor.execute('INSERT INTO images VALUES(?)', [img])

Best will be:

link_to image_tag("Search.png", :border => 0, :alt => '', :title => ''), pages_search_path, :class => 'dock-item'

to stop IIS manually:

1. go to start menu
2. type in IIS

you get a search result for the manager (Internet Information Services (IIS) manager, on the right side of it there are restart/stop/start buttons.

If you don't want IIS to start on startup because its really annoying..:

1. go to start menu.
2. click control panel.
3. click programs.
4. turn windows features on or off
5. wait until the list is loaded
6. search for Internet Information Services (IIS).
7. uncheck the box.
8. Wait until it's done with the changes.
9. restart computer, but then again the info box will tell you to do that anyways (you can leave this for later if you want to).

oh and IIS and xampp basically do the same thing just in a bit different way. ANd if you have Xampp for your projects then its not really all that nessecary to leave it on if you don't ever use it anyways.

If you are trying to build this function within an R package or simply want to reduce complexity, you can do the following:

test_func <- function(df, column) {
  if (column %in% colnames(df)) {
    return(max(df[, column, with=FALSE])) 
  } else {
    stop(cat(column, "not in data.frame columns."))
  }
}

The argument with=FALSE "disables the ability to refer to columns as if they are variables, thereby restoring the “data.frame mode” (per CRAN documentation). The if statement is a quick way to catch if the column name provided is within the data.frame. Could also use tryCatch error handling here.

Laravel 5

This is working for me (i use laravel 5.6).

$collection = MyModel::all()->groupBy('column');

If you want to convert the collection to plain php array, you can use toArray()

$array = MyModel::all()->groupBy('column')->toArray();

Call clearAnimation() on whichever View you called startAnimation().

To show all privileges:

select name from system_privilege_map;

I have used this before and I think in order to make sure credential persist and in a best secure way is

1. you can write them to the app config file using the ConfigurationManager class
2. securing the password using the SecureString class
3. then encrypting it using tools in the Cryptography namespace.

This link will be of great help I hope : Click here

You need no sorted list. You need no sorting at all.

I need to add/remove keys from the list when object is added / removed from database.

But not immediately, the removal can wait. Use an ArrayList containing the ID's all alive objects plus at most some bounded percentage of deleted objects. Use a separate HashSet to keep track of deleted objects.

private List<ID> mostlyAliveIds = new ArrayList<>();
private Set<ID> deletedIds = new HashSet<>();

I want to randomly select few dozens of element from the whole list.

ID selectOne(Random random) {
    checkState(deletedIds.size() < mostlyAliveIds.size());
    while (true) {
        int index = random.nextInt(mostlyAliveIds.size());
        ID id = mostlyAliveIds.get(index);
        if (!deletedIds.contains(ID)) return ID;
    }
}

Set<ID> selectSome(Random random, int count) {
    checkArgument(deletedIds.size() <= mostlyAliveIds.size() - count);
    Set<ID> result = new HashSet<>();
    while (result.size() < count) result.add(selectOne(random));
}

For maintaining the data, do something like

void insert(ID id) {
    if (!deletedIds.remove(id)) mostlyAliveIds.add(ID);
} 

void delete(ID id) {
    if (!deletedIds.add(id)) {
         throw new ImpossibleException("Deleting a deleted element);
    }
    if (deletedIds.size() > 0.1 * mostlyAliveIds.size()) {
        mostlyAliveIds.removeAll(deletedIds);
        deletedIds.clear();
    }
}

The only tricky part is the insert which has to check if an already deleted ID was resurrected.

The delete ensures that no more than 10% of elements in mostlyAliveIds are deleted IDs. When this happens, they get all removed in one sweep (I didn't check the JDK sources, but I hope, they do it right) and the show goes on.

With no more than 10% of dead IDs, the overhead of selectOne is no more than 10% on the average.

I'm pretty sure that it's faster than any sorting as the amortized complexity is O(n).

At the current version of Spring-Boot (1.4.1.RELEASE) , each pooling datasource implementation has its own prefix for properties.

For instance, if you are using tomcat-jdbc:

spring.datasource.tomcat.max-wait=10000

You can find the explanation out here

spring.datasource.max-wait=10000

this have no effect anymore.

For same error code i had quite different reason, I'm sharing here to help

I had web api action like below

public IHttpActionResult GetBooks (int id)

I changed the method to accept two parameters category and author so i changed the parameters as below, i also put the attribute [Httppost]

public IHttpActionResult GetBooks (int category, int author)

I also changed ajax options like below and at this point i start getting error 405 method not allowed

var options = {
    url: '/api/books/GetBooks',
    type: 'POST',
    dataType: 'json',
    cache: false,
    traditional: true, 
    data: {
        category: 1,
        author: 15
    }
}

When i created class for web api action parameters like below error was gone

public class BookParam
{
    public int Category { get; set; }
    public int Author { get; set; }
}
public IHttpActionResult GetBooks (BookParam param)

Introduction to Algorithms by Cormen et. al. is a standard introductory algorithms book, and is used by many universities, including my own. It has pretty good coverage and is very approachable.

And anything by Robert Sedgewick is good too.

I was facing same issue not able to post form without ajax. but found solution , hope it can help and someones time.

<form name="paymentitrform" id="paymentitrform" class="payment"
                    method="post"
                    action="abc.php">
          <input name="email" value="" placeholder="email" />
          <input type="hidden" name="planamount" id="planamount" value="0">
                                <input type="submit" onclick="form_submit() " value="Continue Payment" class="action"
                                    name="planform">

                </form>

You can submit post form, from bootstrap modal using below javascript/jquery code : call the below function onclick of input submit button

    function form_submit() {
        document.getElementById("paymentitrform").submit();
   }  

I know this is a year old but I just came across it with the same problem. My problem was that I didn't have a constructor in my implementation file. I think the problem here could be the comment marks at the end of the header file after the #endif...

This problem turns up all the time in bioinformatics. The accepted answer above (which was great by the way) is known in bioinformatics as the Needleman-Wunsch (compare two strings) and Smith-Waterman (find an approximate substring in a longer string) algorithms. They work great and have been workhorses for decades.

But what if you have a million strings to compare? That's a trillion pairwise comparisons, each of which is O(n*m)! Modern DNA sequencers easily generate a billion short DNA sequences, each about 200 DNA "letters" long. Typically, we want to find, for each such string, the best match against the human genome (3 billion letters). Clearly, the Needleman-Wunsch algorithm and its relatives will not do.

This so-called "alignment problem" is a field of active research. The most popular algorithms are currently able to find inexact matches between 1 billion short strings and the human genome in a matter of hours on reasonable hardware (say, eight cores and 32 GB RAM).

Most of these algorithms work by quickly finding short exact matches (seeds) and then extending these to the full string using a slower algorithm (for example, the Smith-Waterman). The reason this works is that we are really only interested in a few close matches, so it pays off to get rid of the 99.9...% of pairs that have nothing in common.

How does finding exact matches help finding inexact matches? Well, say we allow only a single difference between the query and the target. It is easy to see that this difference must occur in either the right or left half of the query, and so the other half must match exactly. This idea can be extended to multiple mismatches and is the basis for the ELAND algorithm commonly used with Illumina DNA sequencers.

There are many very good algorithms for doing exact string matching. Given a query string of length 200, and a target string of length 3 billion (the human genome), we want to find any place in the target where there is a substring of length k that matches a substring of the query exactly. A simple approach is to begin by indexing the target: take all k-long substrings, put them in an array and sort them. Then take each k-long substring of the query and search the sorted index. Sort and search can be done in O(log n) time.

But storage can be a problem. An index of the 3 billion letter target would need to hold 3 billion pointers and 3 billion k-long words. It would seem hard to fit this in less than several tens of gigabytes of RAM. But amazingly we can greatly compress the index, using the Burrows-Wheeler transform, and it will still be efficiently queryable. An index of the human genome can fit in less than 4 GB RAM. This idea is the basis of popular sequence aligners such as Bowtie and BWA.

Alternatively, we can use a suffix array, which stores only the pointers, yet represents a simultaneous index of all suffixes in the target string (essentially, a simultaneous index for all possible values of k; the same is true of the Burrows-Wheeler transform). A suffix array index of the human genome will take 12 GB of RAM if we use 32-bit pointers.

The links above contain a wealth of information and links to primary research papers. The ELAND link goes to a PDF with useful figures illustrating the concepts involved, and shows how to deal with insertions and deletions.

Finally, while these algorithms have basically solved the problem of (re)sequencing single human genomes (a billion short strings), DNA sequencing technology improves even faster than Moore's law, and we are fast approaching trillion-letter datasets. For example, there are currently projects underway to sequence the genomes of 10,000 vertebrate species, each a billion letters long or so. Naturally, we will want to do pairwise inexact string matching on the data...

If you want to remove activity header & provide a custom view for the dialog add the following to the activity block of you manifest

android:theme="@style/Base.Theme.AppCompat.Dialog"

and design your activity_layout with your desired view

Having been recently bitten by the FP bug reading many wonderful accounts of how neatly the functional paradigm fits with Javascript

I replicate the code for completeness sake and suggest two ways this can be done functionally.

    var carBrands = [];

  var car1 = {name:'ford'};
  var car2 = {name:'lexus'};
  var car3 = {name:'maserati'};
  var car4 = {name:'ford'};
  var car5 = {name:'toyota'};

  carBrands.push(car1);
  carBrands.push(car2);
  carBrands.push(car3);
  carBrands.push(car4);

  // ES6 approach which uses the includes method (Chrome47+, Firefox43+)

  carBrands.includes(car1) // -> true
  carBrands.includes(car5) // -> false

If you need to support older browsers use the polyfill, it seems IE9+ and Edge do NOT support it. Located in polyfill section of MSDN page

Alternatively I would like to propose an updated answer to cdhowie

// ES2015 syntax
function containsObject(obj, list) {

    return list.some(function(elem) {
      return elem === obj
    })
}

// or ES6+ syntax with cool fat arrows
function containsObject(obj, list) {

    return list.some(elem => elem === obj)
}

Recurisvely with ls: (-al for include hidden folders)

ftype="jpg"
ls -1R *.${ftype}  2> /dev/null

The answers here are correct in that IE does not support spaces when setting the title in window.open(), none seem to offer a workaround.

I removed the title from my window.open call (you can use null or ''), and hten added the following to the page being opened:

<script>document.title = 'My new title';</script>

Not ideal by any means, but this will allow you to set the title to whatever you want in all browsers.

The Elvis (?.) Optional Chaining Operator is supported in TypeScript 3.7.

You can use it to check for null values: cats?.miows returns null if cats is null or undefined.

You can also use it for optional method calling: cats.doMiow?.(5) will call doMiow if it exists.

Property access is also possible: cats?.['miows'].

You are looking for --build-arg and the ARG instruction. These are new as of Docker 1.9. Check out https://docs.docker.com/engine/reference/builder/#arg. This will allow you to add ARG arg to the Dockerfile and then build with docker build --build-arg arg=2.3 ..

Of course...

select case substr(status,1,1) -- you're only interested in the first character.
            when 'a' then 'Active'
            when 'i' then 'Inactive'
            when 't' then 'Terminated'
       end as statustext
  from stage.tst

However, there's a few worrying things about this schema. Firstly if you have a column that means something, appending a number onto the end it not necessarily the best way to go. Also, depending on the number of status' you have you might want to consider turning this column into a foreign key to a separate table.

Based on your comment you definitely want to turn this into a foreign key. For instance

create table statuses ( -- Not a good table name :-)
    status varchar2(10)
  , description varchar2(10)
  , constraint pk_statuses primary key (status)
    )

create table tst (
    id number
  , status varchar2(10)
  , constraint pk_tst primary key (id)
  , constraint fk_tst foreign key (status) references statuses (status)
    )

Your query then becomes

select a.status, b.description
  from tst a
  left outer join statuses b
    on a.status = b.status

Here's a SQL Fiddle to demonstrate.

I haven't seen any decompilers that generate C++ code. I've seen a few experimental ones that make a reasonable attempt at generating C code, but they tended to be dependent on matching the code-generation patterns of a particular compiler (that may have changed, it's been awhile since I last looked into this). Of course any symbolic information will be gone. Google for "decompiler".

Didn't see an answer using tag helpers (Core MVC), so here it goes (for a delete action):

On HTML:

<form action="" method="post" role="form">
<table>
@for (var i = 0; i < Model.List.Count(); i++)
{
    <tr>
        <td>@Model.List[i].ItemDescription</td>
        <td>
            <input type="submit" value="REMOVE" class="btn btn-xs btn-danger" 
             asp-controller="ControllerName" asp-action="delete" asp-route-idForDeleteItem="@Model.List[i].idForDeleteItem" />
        </td>
    </tr>
}
</table>
</form>

On Controller:

[HttpPost("[action]/{idForDeleteItem}"), ActionName("Delete")]
public async Task<IActionResult> DeleteConfirmed(long idForDeleteItem)
{
    ///delete with param id goes here
}

Don't forget to use [Route("[controller]")] BEFORE the class declaration - on controller.

String[] tblHead={"Item Name","Price","Qty","Discount"};
DefaultTableModel dtm=new DefaultTableModel(tblHead,0);
JTable tbl=new JTable(dtm);
String[] item={"A","B","C","D"};
dtm.addRow(item);

Here;this is the solution.

I had the same problem, and I found the real cause.

I had written some concurrent / multi-threads code, while I added some breakpoints inside the code running in a new thread. So, when JUnit tests ran over, and stopped soon, the code will not reach and stop at the breakpoints.

For this situation, we have to click and select "Keep JUnit running after a test run when debugging" check box at "Debug Configurations..."

This is not "wrong" at all, it's just not what the cool guys typically do with MVC. As an aside, I wish some of the early demos of ASP.NET MVC didn't try to cram in Linq-to-Sql at the same time. It's pretty awesome and well suited for MVC, sure, but it's not required. There is nothing about MVC that prevents you from using ADO.NET. For example:

Controller action:

public ActionResult Index()
{
    ViewData["Message"] = "Welcome to ASP.NET MVC!";

    DataTable dt = new DataTable("MyTable");
    dt.Columns.Add(new DataColumn("Col1", typeof(string)));
    dt.Columns.Add(new DataColumn("Col2", typeof(string)));
    dt.Columns.Add(new DataColumn("Col3", typeof(string)));

    for (int i = 0; i < 3; i++)
    {
        DataRow row = dt.NewRow();
        row["Col1"] = "col 1, row " + i;
        row["Col2"] = "col 2, row " + i;
        row["Col3"] = "col 3, row " + i;
        dt.Rows.Add(row);
    }

    return View(dt); //passing the DataTable as my Model
}

View: (w/ Model strongly typed as System.Data.DataTable)

<table border="1">
    <thead>
        <tr>
            <%foreach (System.Data.DataColumn col in Model.Columns) { %>
                <th><%=col.Caption %></th>
            <%} %>
        </tr>
    </thead>
    <tbody>
    <% foreach(System.Data.DataRow row in Model.Rows) { %>
        <tr>
            <% foreach (var cell in row.ItemArray) {%>
                <td><%=cell.ToString() %></td>
            <%} %>
        </tr>
    <%} %>         
    </tbody>
</table>

Now, I'm violating a whole lot of principles and "best-practices" of ASP.NET MVC here, so please understand this is just a simple demonstration. The code creating the DataTable should reside somewhere outside of the controller, and the code in the View might be better isolated to a partial, or html helper, to name a few ways you should do things.

You absolutely are supposed to pass objects to the View, if the view is supposed to present them. (Separation of concerns dictates the view shouldn't be responsible for creating them.) In this case I passed the DataTable as the actual view Model, but you could just as well have put it in ViewData collection. Alternatively you might make a specific IndexViewModel class that contains the DataTable and other objects, such as the welcome message.

I hope this helps!

Assuming you did not commit the file, or add it to the index, then:

git checkout -- filename

Assuming you added it to the index, but did not commit it, then:

git reset HEAD filename
git checkout -- filename

Assuming you did commit it, then:

git checkout origin/master filename

Assuming you want to blow away all commits from your branch (VERY DESTRUCTIVE):

git reset --hard origin/master

PAGEIOLATCH_SH wait type usually comes up as the result of fragmented or unoptimized index.

Often reasons for excessive PAGEIOLATCH_SH wait type are:

• I/O subsystem has a problem or is misconfigured
• Overloaded I/O subsystem by other processes that are producing the high I/O activity
• Bad index management
• Logical or physical drive misconception
• Network issues/latency
• Memory pressure
• Synchronous Mirroring and AlwaysOn AG

In order to try and resolve having high PAGEIOLATCH_SH wait type, you can check:

• SQL Server, queries and indexes, as very often this could be found as a root cause of the excessive PAGEIOLATCH_SH wait types
• For memory pressure before jumping into any I/O subsystem troubleshooting

Always keep in mind that in case of high safety Mirroring or synchronous-commit availability in AlwaysOn AG, increased/excessive PAGEIOLATCH_SH can be expected.

You can find more details about this topic in the article Handling excessive SQL Server PAGEIOLATCH_SH wait types

After creating your client specifying the binding and endpoint address, you can assign an OperationTimeout,

client.InnerChannel.OperationTimeout = new TimeSpan(0, 5, 0);

I am assuming you are using msys git. If you are, the editor that is popping up to write your commit message is vim. Vim is not friendly at first. You may prefer to switch to a different editor. If you want to use a different editor, look at this answer: How do I use Notepad++ (or other) with msysgit?

If you want to use vim, type i to type in your message. When happy hit ESC. Then type :wq, and git will then be happy.

Or just type git commit -m "your message here" to skip the editor altogether.

You should also use the style 'color' and not 'font-color'

<?php

foreach($months as $key => $month){
  if(strpos($filename,$month)!==false){
        echo "<style = 'color: #ff0000;'> Movie List for {$key} 2013 </style>";
    }
}

?>

In general, the comments on double and single quotes are correct in other suggestions. $Variables only execute in double quotes.

Try use system "rmdir -s -q file_to_delte".
This will delete the folder and all files in it.

The return type of Html.RenderAction is void that means it directly renders the responses in View where the return type of Html.Action is MvcHtmlString You can catch its render view in controller and modify it by using following method

protected string RenderPartialViewToString(string viewName, object model)
    {
        if (string.IsNullOrEmpty(viewName))
            viewName = ControllerContext.RouteData.GetRequiredString("action");

        ViewData.Model = model;

        using (StringWriter sw = new StringWriter())
        {
            ViewEngineResult viewResult = ViewEngines.Engines.FindPartialView(ControllerContext, viewName);
            ViewContext viewContext = new ViewContext(ControllerContext, viewResult.View, ViewData, TempData, sw);
            viewResult.View.Render(viewContext, sw);
            return sw.GetStringBuilder().ToString();
        }
    }

This will return the Html string of the View.

This is also applicable to Html.Partial and Html.RenderPartial

I had the same issue. This Microsoft support article fixed it for me.
https://support.microsoft.com/en-us/help/2023146/mvc-2-and-asp.net-4-web-forms-applications-that-use-url-routing-might-return-http-404-errors-when-they-attempt-to-process-extensionless-urls-on-iis-7-and-iis-7.5

In the "Turn Windows Features On or Off" dialog box of the Windows Control Panel "Programs and Features" application, perform the following steps:

1. Navigate to the following node: Internet Information Services --> World Wide Web Services --> Common HTTP Features
2. Make sure that the "HTTP Error Redirection" option is selected.

-or-

1. Navigate to the following node: Internet Information Services --> World Wide Web Services --> Performance Features
2. Make sure that the "Static Content Compression" option is selected. After either option has been selected, click "OK" to save changes.

Re-enabling either the HTTP Error Redirection module or the Static Content Compression module ensures that ASP.NET and IIS correctly synchronize HTTP pipeline events. This enables the URL routing module to process extensionsless URLs.

The most obvious solutions are already listed. Depending on where the query is sat (i.e. in application code) you can't always use IF statements and the inline CASE statements can get painful where lots of columns become conditional. Assuming Col1 + Col3 + Col7 are the same type, and likewise Col2, Col4 + Col8 you can do this:

SELECT Col1, Col2 FROM tbl WHERE @Var LIKE 'xyz'
UNION ALL
SELECT Col3, Col4 FROM tbl WHERE @Var LIKE 'zyx'
UNION ALL
SELECT Col7, Col8 FROM tbl WHERE @Var NOT LIKE 'xyz' AND @Var NOT LIKE 'zyx'

As this is a single command there are several performance benefits with regard to plan caching. Also the Query Optimiser will quickly eliminate those statements where @Var doesn't match the appropriate value without touching the storage engine.

var http = require('http');
var url  = require('url');
var fs   = require('fs');

var neededstats = [];

http.createServer(function(req, res) {
    if (req.url == '/index.html' || req.url == '/') {
        fs.readFile('./index.html', function(err, data) {
            res.end(data);
        });
    } else {
        var p = __dirname + '/' + req.params.filepath;
        fs.stat(p, function(err, stats) {
            if (err) {
                throw err;
            }
            neededstats.push(stats.mtime);
            neededstats.push(stats.size);
            res.send(neededstats);
        });
    }
}).listen(8080, '0.0.0.0');
console.log('Server running.');

I have not tested your code but other things works

If you want to get the path info from request url

 var url_parts = url.parse(req.url);
 console.log(url_parts);
 console.log(url_parts.pathname);

1.If you are getting the URL parameters still not able to read the file just correct your file path in my example. If you place index.html in same directory as server code it would work...

2.if you have big folder structure that you want to host using node then I would advise you to use some framework like expressjs

If you want raw solution to file path

var http = require("http");
var url = require("url");

function start() {
function onRequest(request, response) {
    var pathname = url.parse(request.url).pathname;
    console.log("Request for " + pathname + " received.");
    response.writeHead(200, {"Content-Type": "text/plain"});
    response.write("Hello World");
    response.end();
}

http.createServer(onRequest).listen(8888);
console.log("Server has started.");
}

exports.start = start;

The following suggestion let's you test abstract classes without creating a "real" subclass - the Mock is the subclass.

use Mockito.mock(My.class, Mockito.CALLS_REAL_METHODS), then mock any abstract methods that are invoked.

Example:

public abstract class My {
  public Result methodUnderTest() { ... }
  protected abstract void methodIDontCareAbout();
}

public class MyTest {
    @Test
    public void shouldFailOnNullIdentifiers() {
        My my = Mockito.mock(My.class, Mockito.CALLS_REAL_METHODS);
        Assert.assertSomething(my.methodUnderTest());
    }
}

Note: The beauty of this solution is that you do not have to implement the abstract methods, as long as they are never invoked.

In my honest opinion, this is neater than using a spy, since a spy requires an instance, which means you have to create an instantiatable subclass of your abstract class.

One cause for this crash is that ArrayList object cannot change completely. So, when I remove an item, I have to do this:

mList.clear();
mList.addAll(newDataList);

This fixed the crash for me.

Thread safe simply means that it may be used from multiple threads at the same time without causing problems. This can mean that access to any resources are synchronized, or whatever.

Easily done in 2 steps:

dictionary[new_key] = dictionary[old_key]
del dictionary[old_key]

Or in 1 step:

dictionary[new_key] = dictionary.pop(old_key)

which will raise KeyError if dictionary[old_key] is undefined. Note that this will delete dictionary[old_key].

>>> dictionary = { 1: 'one', 2:'two', 3:'three' }
>>> dictionary['ONE'] = dictionary.pop(1)
>>> dictionary
{2: 'two', 3: 'three', 'ONE': 'one'}
>>> dictionary['ONE'] = dictionary.pop(1)
Traceback (most recent call last):
  File "<input>", line 1, in <module>
KeyError: 1

AngularJS's Filter worked out for me.

Assuming the code/id is unique, we can filter out that particular object with AngularJS's filter and work with the selected objects properties. Considering the example above:

<select ng-options="size.code as size.name for size in sizes" 
        ng-model="item.size.code" 
        ng-change="update(MAGIC_THING); search.code = item.size.code">
</select>

<!-- OUTSIDE THE SELECT BOX -->

<h1 ng-repeat="size in sizes | filter:search:true"
    ng-init="search.code = item.size.code">
  {{size.name}}
</h1>

Now, there are 3 important aspects to this:

1. ng-init="search.code = item.size.code" - on initializing h1 element outside select box, set the filter query to the selected option.

2. ng-change="update(MAGIC_THING); search.code = item.size.code" - when you change the select input, we'll run one more line which will set the "search" query to the currently selected item.size.code.

3. filter:search:true - Pass true to filter to enable strict matching.

That's it. If the size.code is uniqueID, we'll have only one h1 element with the text of size.name.

I've tested this in my project and it works.

Good Luck

Wow. I found this solution, but nothing worked like I wanted. But this is so good:

EventHandlerList listaEventos;

private void btnDetach_Click(object sender, EventArgs e)
{
    listaEventos = DetachEvents(comboBox1);
}

private void btnAttach_Click(object sender, EventArgs e)
{
    AttachEvents(comboBox1, listaEventos);
}

public EventHandlerList DetachEvents(Component obj)
{
    object objNew = obj.GetType().GetConstructor(new Type[] { }).Invoke(new object[] { });
    PropertyInfo propEvents = obj.GetType().GetProperty("Events", BindingFlags.NonPublic | BindingFlags.Instance);

    EventHandlerList eventHandlerList_obj = (EventHandlerList)propEvents.GetValue(obj, null);
    EventHandlerList eventHandlerList_objNew = (EventHandlerList)propEvents.GetValue(objNew, null);

    eventHandlerList_objNew.AddHandlers(eventHandlerList_obj);
    eventHandlerList_obj.Dispose();

    return eventHandlerList_objNew;
}

public void AttachEvents(Component obj, EventHandlerList eventos)
{
    PropertyInfo propEvents = obj.GetType().GetProperty("Events", BindingFlags.NonPublic | BindingFlags.Instance);

    EventHandlerList eventHandlerList_obj = (EventHandlerList)propEvents.GetValue(obj, null);

    eventHandlerList_obj.AddHandlers(eventos);

Locale-independent one liner to get any date format you like. I use it to generate archive names. Back quote option is needed because PowerShell command line is using single quotes.

:: Get date in yyyyMMdd_HHmm format to use with file name.
FOR /f "usebackq" %%i IN (`PowerShell ^(Get-Date^).ToString^('yyyy-MM-dd'^)`) DO SET DTime=%%i

:: Get formatted yesterday date.
FOR /f "usebackq" %%i IN (`PowerShell ^(Get-Date^).AddDays^(-1^).ToString^('yyyy-MM-dd'^)`) DO SET DTime=%%i

:: Show file name with the date.
echo Archive.%DTime%.zip

If you try and reference an undeclared variable, an error will be thrown in all JavaScript implementations.

Properties of objects aren't subject to the same conditions. If an object property hasn't been defined, an error won't be thrown if you try and access it. So in this situation you could shorten:

 if (typeof(myObj.some_property) != "undefined" && myObj.some_property != null)

to

if (myObj.some_property != null)

With this in mind, and the fact that global variables are accessible as properties of the global object (window in the case of a browser), you can use the following for global variables:

if (window.some_variable != null) {
    // Do something with some_variable
}

In local scopes, it always useful to make sure variables are declared at the top of your code block, this will save on recurring uses of typeof.

A good reason, which you have sort of touched on, is that once the CSRF cookie has been received, it is then available for use throughout the application in client script for use in both regular forms and AJAX POSTs. This will make sense in a JavaScript heavy application such as one employed by AngularJS (using AngularJS doesn't require that the application will be a single page app, so it would be useful where state needs to flow between different page requests where the CSRF value cannot normally persist in the browser).

Consider the following scenarios and processes in a typical application for some pros and cons of each approach you describe. These are based on the Synchronizer Token Pattern.

Request Body Approach

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. If not yet generated for this session, server generates CSRF token, stores it against the user session and outputs it to a hidden field.
5. User submits form.
6. Server checks hidden field matches session stored token.

Advantages:

• Simple to implement.
• Works with AJAX.
• Works with forms.
• Cookie can actually be HTTP Only.

Disadvantages:

• All forms must output the hidden field in HTML.
• Any AJAX POSTs must also include the value.
• The page must know in advance that it requires the CSRF token so it can include it in the page content so all pages must contain the token value somewhere, which could make it time consuming to implement for a large site.

Custom HTTP Header (downstream)

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. Page loads in browser, then an AJAX request is made to retrieve the CSRF token.
5. Server generates CSRF token (if not already generated for session), stores it against the user session and outputs it to a header.
6. User submits form (token is sent via hidden field).
7. Server checks hidden field matches session stored token.

Advantages:

• Works with AJAX.
• Cookie can be HTTP Only.

Disadvantages:

• Doesn't work without an AJAX request to get the header value.
• All forms must have the value added to its HTML dynamically.
• Any AJAX POSTs must also include the value.
• The page must make an AJAX request first to get the CSRF token, so it will mean an extra round trip each time.
• Might as well have simply output the token to the page which would save the extra request.

Custom HTTP Header (upstream)

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. If not yet generated for this session, server generates CSRF token, stores it against the user session and outputs it in the page content somewhere.
5. User submits form via AJAX (token is sent via header).
6. Server checks custom header matches session stored token.

Advantages:

• Works with AJAX.
• Cookie can be HTTP Only.

Disadvantages:

• Doesn't work with forms.
• All AJAX POSTs must include the header.

Custom HTTP Header (upstream & downstream)

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. Page loads in browser, then an AJAX request is made to retrieve the CSRF token.
5. Server generates CSRF token (if not already generated for session), stores it against the user session and outputs it to a header.
6. User submits form via AJAX (token is sent via header) .
7. Server checks custom header matches session stored token.

Advantages:

• Works with AJAX.
• Cookie can be HTTP Only.

Disadvantages:

• Doesn't work with forms.
• All AJAX POSTs must also include the value.
• The page must make an AJAX request first to get the CRSF token, so it will mean an extra round trip each time.

Set-Cookie

1. User successfully logs in.
2. Server issues auth cookie.
3. User clicks to navigate to a form.
4. Server generates CSRF token, stores it against the user session and outputs it to a cookie.
5. User submits form via AJAX or via HTML form.
6. Server checks custom header (or hidden form field) matches session stored token.
7. Cookie is available in browser for use in additional AJAX and form requests without additional requests to server to retrieve the CSRF token.

Advantages:

• Simple to implement.
• Works with AJAX.
• Works with forms.
• Doesn't necessarily require an AJAX request to get the cookie value. Any HTTP request can retrieve it and it can be appended to all forms/AJAX requests via JavaScript.
• Once the CSRF token has been retrieved, as it is stored in a cookie the value can be reused without additional requests.

Disadvantages:

• All forms must have the value added to its HTML dynamically.
• Any AJAX POSTs must also include the value.
• The cookie will be submitted for every request (i.e. all GETs for images, CSS, JS, etc, that are not involved in the CSRF process) increasing request size.
• Cookie cannot be HTTP Only.

So the cookie approach is fairly dynamic offering an easy way to retrieve the cookie value (any HTTP request) and to use it (JS can add the value to any form automatically and it can be employed in AJAX requests either as a header or as a form value). Once the CSRF token has been received for the session, there is no need to regenerate it as an attacker employing a CSRF exploit has no method of retrieving this token. If a malicious user tries to read the user's CSRF token in any of the above methods then this will be prevented by the Same Origin Policy. If a malicious user tries to retrieve the CSRF token server side (e.g. via curl) then this token will not be associated to the same user account as the victim's auth session cookie will be missing from the request (it would be the attacker's - therefore it won't be associated server side with the victim's session).

As well as the Synchronizer Token Pattern there is also the Double Submit Cookie CSRF prevention method, which of course uses cookies to store a type of CSRF token. This is easier to implement as it does not require any server side state for the CSRF token. The CSRF token in fact could be the standard authentication cookie when using this method, and this value is submitted via cookies as usual with the request, but the value is also repeated in either a hidden field or header, of which an attacker cannot replicate as they cannot read the value in the first place. It would be recommended to choose another cookie however, other than the authentication cookie so that the authentication cookie can be secured by being marked HttpOnly. So this is another common reason why you'd find CSRF prevention using a cookie based method.

I suggest create a list and append dictionary into it.

x   = []
cur = db.dbname.find()
for i in cur:
    x.append(i)
print(x)

Now x is a list of dictionary, you can manipulate the same in usual python way.

There is the conditional expression:

a if cond else b

but this is an expression, not a statement.

In if statements, the if (or elif or else) can be written on the same line as the body of the block if the block is just one like:

if something: somefunc()
else: otherfunc()

but this is discouraged as a matter of formatting-style.

If you don't want the controller to decide the return object type, you should set your method return type as System.Net.Http.HttpResponseMessage and use the below code to return the XML.

public HttpResponseMessage Authenticate()
{
  //process the request 
  .........

  string XML="<note><body>Message content</body></note>";
  return new HttpResponseMessage() 
  { 
    Content = new StringContent(XML, Encoding.UTF8, "application/xml") 
  };
}

This is the quickest way to always return XML from Web API.

To remove rows based on Nan value of particular column:

d= pd.DataFrame([[2,3],[4,None]])   #creating data frame
d
Output:
    0   1
0   2   3.0
1   4   NaN

d = d[np.isfinite(d[1])]  #Select rows where value of 1st column is not nan
d

Output:
    0   1
0   2   3.0

Ran into a similar issue the solution for me was to run fuser -k 'filename.db' on the file that had a lock associated with it.

Hope this helps!

ADD ../../home/ubuntu/.ssh/id_rsa /root/.ssh/id_rsa

When specifying the files you want to copy into the image you can only use relative paths - relative to the directory where your Dockerfile is. So you should instead use:

ADD id_rsa /root/.ssh/id_rsa

And put the id_rsa file into the same directory where your Dockerfile is.

Check this out for more details: http://docs.docker.io/reference/builder/#add

add android:focusableInTouchMode="true" in root layout, when edit text will be clicked at that time cursor will be shown.

The basic idea behing the XToOnes in Hibernate is that they are not lazy in most case.

One reason is that, when Hibernate have to decide to put a proxy (with the id) or a null,
it has to look into the other table anyway to join. The cost of accessing the other table in the database is significant, so it might as well fetch the data for that table at that moment (non-lazy behaviour), instead of fetching that in a later request that would require a second access to the same table.

Edited: for details, please refer to ChssPly76 's answer. This one is less accurate and detailed, it has nothing to offer. Thanks ChssPly76.

.show-grid [class*="span"]

It's a CSS selector that selects all elements with the class show-grid that has a child element whose class contains the name span.

I use LuaSocket to get more precision.

require "socket"
print("Milliseconds: " .. socket.gettime()*1000)

This adds a dependency of course, but works fine for personal use (in benchmarking scripts for example).

This answer is a bit of expansion for @rastating's great answer. You can use the following code for all versions of .NET without any worries:

    public static void SetDefaultCulture(CultureInfo culture)
    {
        Type type = typeof (CultureInfo);
        try
        {
            // Class "ReflectionContext" exists from .NET 4.5 onwards.
            if (Type.GetType("System.Reflection.ReflectionContext", false) != null)
            {
                type.GetProperty("DefaultThreadCurrentCulture")
                    .SetValue(System.Threading.Thread.CurrentThread.CurrentCulture,
                        culture, null);

                type.GetProperty("DefaultThreadCurrentUICulture")
                    .SetValue(System.Threading.Thread.CurrentThread.CurrentCulture,
                        culture, null);
            }
            else //.NET 4 and lower
            {
                type.InvokeMember("s_userDefaultCulture",
                    BindingFlags.SetField | BindingFlags.NonPublic | BindingFlags.Static,
                    null,
                    culture,
                    new object[] {culture});

                type.InvokeMember("s_userDefaultUICulture",
                    BindingFlags.SetField | BindingFlags.NonPublic | BindingFlags.Static,
                    null,
                    culture,
                    new object[] {culture});

                type.InvokeMember("m_userDefaultCulture",
                    BindingFlags.SetField | BindingFlags.NonPublic | BindingFlags.Static,
                    null,
                    culture,
                    new object[] {culture});

                type.InvokeMember("m_userDefaultUICulture",
                    BindingFlags.SetField | BindingFlags.NonPublic | BindingFlags.Static,
                    null,
                    culture,
                    new object[] {culture});
            }
        }
        catch
        {
            // ignored
        }
    }
}

Am adding this answer for the purpose of those who google about this..

There was an episode of DevBytes (ListView Cell Dragging and Rearranging) recently which explains how to do this

You can find it here also the sample code is available here.

What this code basically does is that it creates a dynamic listview by the extension of listview that supports cell dragging and swapping. So that you can use the DynamicListView instead of your basic ListView and that's it you have implemented a ListView with Drag and Drop.

As of August 8th, 2016, FQLs are deprecated.

Update 10/2017 (v2.10):

Here's a non-deprecated way to get a given URL's like and share count (no access token required):

https://graph.facebook.com/?fields=og_object{likes.summary(total_count).limit(0)},share&id=https://www.stackoverflow.com

Result:

{
   "og_object": {
      "likes": {
         "data": [

         ],
         "summary": {
            "total_count": 83
         }
      },
      "id": "10151023731873397"
   },
   "share": {
      "comment_count": 0,
      "share_count": 2915
   },
   "id": "https://www.stackoverflow.com"
}

JQuery Example:

$.get('https://graph.facebook.com/'
    + '?fields=og_object{likes.summary(total_count).limit(0)},share&id='
    + url-goes-here,
    function (data) {
        if (data) {
            var like_count = data.og_object.likes.summary.total_count;
            var share_count = data.share.share_count;
        }
    });

Edit:

  <form (submit)="submit()" >
    <input />
    <button type="submit" style="display:none">hidden submit</button>
  </form>

In order to use this method, you need to have a submit button even if it's not displayed "Thanks for Toolkit's answer"

Old Answer:

Yes, exactly as you wrote it, except the event name is (submit) instead of (ngSubmit):

<form [ngFormModel]="xxx" (submit)="xxxx()">
  <input [(ngModel)]="lxxR"   ngControl="xxxxx"/>
</form>

I feel this question need a bit more details. My answer is inspired from the Android Programming, The Big Nerd Ranch Guide (2nd edition).

By default, JavaScript is off in WebView. You do not always need to have it on, but for some apps, might do require it.

Loading the URL has to be done after configuring the WebView, so you do that last. Before that, you turn JavaScript on by calling getSettings() to get an instance of WebSettings and calling WebSettings.setJavaScriptEnabled(true). WebSettings is the first of the three ways you can modify your WebView. It has various properties you can set, like the user agent string and text size.

After that, you configure your WebViewClient. WebViewClient is an event interface. By providing your own implementation of WebViewClient, you can respond to rendering events. For example, you could detect when the renderer starts loading an image from a particular URL or decide whether to resubmit a POST request to the server.

WebViewClient has many methods you can override, most of which you will not deal with. However, you do need to replace the default WebViewClient’s implementation of shouldOverrideUrlLoading(WebView, String). This method determines what will happen when a new URL is loaded in the WebView, like by pressing a link. If you return true, you are saying, “Do not handle this URL, I am handling it myself.” If you return false, you are saying, “Go ahead and load this URL, WebView, I’m not doing anything with it.”

The default implementation fires an implicit intent with the URL, just like you did earlier. Now, though, this would be a severe problem. The first thing some Web Applications does is redirect you to the mobile version of the website. With the default WebViewClient, that means that you are immediately sent to the user’s default web browser. This is just what you are trying to avoid. The fix is simple – just override the default implementation and return false.

Use WebChromeClient to spruce things up Since you are taking the time to create your own WebView, let’s spruce it up a bit by adding a progress bar and updating the toolbar’s subtitle with the title of the loaded page.

To hook up the ProgressBar, you will use the second callback on WebView: WebChromeClient.

WebViewClient is an interface for responding to rendering events; WebChromeClient is an event interface for reacting to events that should change elements of chrome around the browser. This includes JavaScript alerts, favicons, and of course updates for loading progress and the title of the current page.

Hook it up in onCreateView(…). Using WebChromeClient to spruce things up Progress updates and title updates each have their own callback method, onProgressChanged(WebView, int) and onReceivedTitle(WebView, String). The progress you receive from onProgressChanged(WebView, int) is an integer from 0 to 100. If it is 100, you know that the page is done loading, so you hide the ProgressBar by setting its visibility to View.GONE.

I went searching around for a similar question - the way I've managed to initialize a Git repository for an existing project file is this (disclaimer: this is done in Visual Studio 2013 Express, without a Team Foundation Server setup):

1. Open the project in Visual Studio.
2. Go to menu File ? Add to Source Control.

That did it for me - assuming Git is set up for you, you can go to menu View ? Team Explorer, then double click the repository for your project file, and make your initial commit (making sure to add whatever files you'd like).

Here is a work around for inner bordered rect using symbol and use.

Example: https://jsbin.com/yopemiwame/edit?html,output

SVG:

<svg>
  <symbol id="inner-border-rect">
    <rect class="inner-border" width="100%" height="100%" style="fill:rgb(0,255,255);stroke-width:10;stroke:rgb(0,0,0)">
  </symbol>
  ...
  <use xlink:href="#inner-border-rect" x="?" y="?" width="?" height="?">
</svg>

Note: Make sure to replace the ? in use with real values.

Background: The reason why this works is because symbol establishes a new viewport by replacing symbol with svg and creating an element in the shadow DOM. This svg of the shadow DOM is then linked into your current SVG element. Note that svgs can be nested and every svg creates a new viewport, which clips everything that overlaps, including the overlapping border. For a much more detailed overview of whats going on read this fantastic article by Sara Soueidan.

For multiple files; note the newer "multiple" attribute for input:

Form:

@using (Html.BeginForm("FileImport","Import",FormMethod.Post, new {enctype = "multipart/form-data"}))
{
    <label for="files">Filename:</label>
    <input type="file" name="files" multiple="true" id="files" />
    <input type="submit"  />
}

Controller:

[HttpPost]
public ActionResult FileImport(IEnumerable<HttpPostedFileBase> files)
{
    return View();
}

You should be malloc'ing strlen(ptr), not strlen(buf). Also, your count2 should be limited to the number of words. When you get to the end of your string, you continue going over the zeros in your buffer and adding zero size strings to your array.

i think the best way is by theme:

<style name="MyEditTextTheme" parent="Theme.AppCompat.Light.DarkActionBar">
        <item name="colorControlNormal">@color/black</item>
        <item name="colorControlActivated">@color/action_blue</item>
        <item name="colorControlHighlight">@color/action_blue</item>
</style>

<style name="AddressBookStyle" parent="Theme.AppCompat.Light.DarkActionBar">
     <item name="android:layout_width">match_parent</item>
     <item name="android:layout_height">wrap_content</item>
     <item name="android:textSize">13sp</item>
     <item name="android:theme">@style/MyEditTextTheme</item>
</style>

<android.support.v7.widget.AppCompatEditText
            style="@style/AddressBookStyle"/>

without looking at your input file, only a guess

awk '{$1=$1}1' OFS=","

redirect to another file and rename as needed

How I do:

# Remove python2
sudo apt purge -y python2.7-minimal

# You already have Python3 but 
# don't care about the version 
sudo ln -s /usr/bin/python3 /usr/bin/python

# Same for pip
sudo apt install -y python3-pip
sudo ln -s /usr/bin/pip3 /usr/bin/pip

# Confirm the new version of Python: 3
python --version

Simple and easy:

$this->db->order_by("name", "asc");
$query = $this->db->get($this->table_name);
return $query->result();

Try this

$.trim($("#spa").val()).length > 0

It will not treat any white space if any as a correct value

If you're looking to store the current time just use MYSQL's functions.

mysql_query("INSERT INTO `table` (`dateposted`) VALUES (now())");

If you need to use PHP to do it, the format it Y-m-d H:i:s so try

$date = date('Y-m-d H:i:s');
mysql_query("INSERT INTO `table` (`dateposted`) VALUES ('$date')");

Try to find out if DAO or the Repository pattern is most applicable to the following situation : Imagine you would like to provide a uniform data access API for a persistent mechanism to various types of data sources such as RDBMS, LDAP, OODB, XML repositories and flat files.

I tried the Visual Studio Project Renamer, but, it threw exceptions in the few cases where I tried it.

I have had good success with CopyWiz.

I am in no way affiliated with them, and I have not yet paid for it, but I may have to soon, as it is the only tool that seems to work for both my C# and C++ projects. I do hope they make a little money, and continue to improve it, though.

This should work for matches that might overlap:

public static void main(String[] args) {
    String input = "aaaaaaaa";
    String regex = "aa";
    Pattern pattern = Pattern.compile(regex);
    Matcher matcher = pattern.matcher(input);
    int from = 0;
    int count = 0;
    while(matcher.find(from)) {
        count++;
        from = matcher.start() + 1;
    }
    System.out.println(count);
}

You can try something like this:

    <script type="text/javascript">
        function simulateLogin(userName)
        {
            var userNameField = document.getElementById("username");
            userNameField.value = userName;
            var goButton = document.getElementById("go");
            goButton.click();
        }

        simulateLogin("testUser");
</script>

In Android simply edit your styles.xml file under Resources\values adding this:

<resources>
  <style name="MyTheme" parent="android:style/Theme.Material.Light.DarkActionBar">
   <item name="android:colorPressedHighlight">@color/ListViewSelected</item>
   <item name="android:colorLongPressedHighlight">@color/ListViewHighlighted</item>
   <item name="android:colorFocusedHighlight">@color/ListViewSelected</item>
   <item name="android:colorActivatedHighlight">@color/ListViewSelected</item>
   <item name="android:activatedBackgroundIndicator">@color/ListViewSelected</item>
  </style>
<color name="ListViewSelected">#96BCE3</color>
<color name="ListViewHighlighted">#E39696</color>
</resources>

This is very simple. Here is the code.

[yourLabel setFont:[UIFont boldSystemFontOfSize:15.0];

This will help you.

private void validateInput() {

      if (filenametextfield.getText().length() <= 3 )
        {

          errorMsg2.setForeground(Color.RED);

        }
        else if(filenametextfield.getText().length() >= 3 && filenametextfield.getText().length()<= 25)
        {

             errorMsg2.setForeground(frame.getBackground());
             errorMsg.setForeground(frame2.getBackground());

        } 
        else if(filenametextfield.getText().length() >= 25)
        {

             remove(errorMsg2);
             errorMsg.setForeground(Color.RED);
             filenametextfield.addKeyListener(new KeyAdapter() {
                  public void keyTyped(KeyEvent e) {
                     if(filenametextfield.getText().length()>=25)
                        {
                         e.consume();
                         e.getModifiers();

                        }
                 }
            });
        }


    }

This will show a model's weights and parameters (but not output shape).

            torch.nn.modules.container.Sequential
        ]:
            modstr = torch_summarize(module)
        else:
            modstr = module.__repr__()
        modstr = _addindent(modstr, 2)

        params = sum([np.prod(p.size()) for p in module.parameters()])
        weights = tuple([tuple(p.size()) for p in module.parameters()])

        tmpstr += '  (' + key + '): ' + modstr

        tmpstr += '\n'   

    tmpstr = tmpstr + ')'
    return tmpstr

Edit: isaykatsman has a pytorch PR to add a model.summary() that is exactly like keras https://github.com/pytorch/pytorch/pull/3043/files

I would suggest to pass the JSON data in the body as a POST request.But if you still want to pass this as a parameter in URL,you will have to encode your URL like below just for example:-

for ex json is :->{"name":"ABC","id":"1"}

testurl:80/service?data=%7B%22name%22%3A%22ABC%22%2C%22id%22%3A%221%22%7D

for more information on URL encoding refer below

https://en.wikipedia.org/wiki/Percent-encoding

Why not use controller inheritance, all methods/properties defined in scope of HeaderCtrl are accessible in the controller inside ng-view. $scope.servHelper is accessible in all your controllers.

    angular.module('fnetApp').controller('HeaderCtrl', function ($scope, MyHelperService) {
      $scope.servHelper = MyHelperService;
    });


<div ng-controller="HeaderCtrl">
  <div ng-view=""></div>
</div>

Try to modify the eclipse.ini so that both Xms and Xmx are of the same value:

-Xms6000m
-Xmx6000m

This should force the Eclipse's VM to allocate 6GB of heap right from the beginning.

But be careful about either using the eclipse.ini or the command-line ./eclipse/eclipse -vmargs .... It should work in both cases but pick one and try to stick with it.

I used this code to fix the issue of displaying items in the horizontal list.

new Container(
      height: 20,
      child: Row(
        mainAxisAlignment: MainAxisAlignment.end,
        children: <Widget>[
          ListView.builder(
            scrollDirection: Axis.horizontal,
            shrinkWrap: true,
            itemCount: array.length,
            itemBuilder: (context, index){
              return array[index];
            },
          ),
        ],
      ),
    );

Here is another way to change DNS by using WMIC (Windows Management Instrumentation Command-line).

The commands must be run as administrator to apply.

Clear DNS servers:

wmic nicconfig where (IPEnabled=TRUE) call SetDNSServerSearchOrder ()

Set 1 DNS server:

wmic nicconfig where (IPEnabled=TRUE) call SetDNSServerSearchOrder ("8.8.8.8")

Set 2 DNS servers:

wmic nicconfig where (IPEnabled=TRUE) call SetDNSServerSearchOrder ("8.8.8.8", "8.8.4.4")

Set 2 DNS servers on a particular network adapter:

wmic nicconfig where "(IPEnabled=TRUE) and (Description = 'Local Area Connection')" call SetDNSServerSearchOrder ("8.8.8.8", "8.8.4.4")

Another example for setting the domain search list:

wmic nicconfig call SetDNSSuffixSearchOrder ("domain.tld")

string = string.replace(/[&\/\\#,+()$~%.'":*?<>{}]/g,'_');

Alternatively, to change all characters except numbers and letters, try:

string = string.replace(/[^a-zA-Z0-9]/g,'_');

My approach is based on Nicks' answer and hopefully is a bit more usable for multiple (as many as needed, not only two) permissions. It suggests adding single-responsibility PermissionsHelper class:

import android.app.Activity;
import android.app.AlertDialog;
import android.content.pm.PackageManager;
import android.support.v4.app.ActivityCompat;
import android.support.v4.content.ContextCompat;
import android.util.Log;

import java.util.ArrayList;
import java.util.HashMap;
import java.util.List;
import java.util.Map;

public class PermissionsHelper {

private static final int REQUEST_ID_MULTIPLE_PERMISSIONS = 100; // any code you want.

public void checkAndRequestPermissions(Activity activity, String... permissions) {
    List<String> listPermissionsNeeded = new ArrayList<>();
    for (String permission : permissions) {
        if (ContextCompat.checkSelfPermission(activity, permission) != PackageManager.PERMISSION_GRANTED) {
            listPermissionsNeeded.add(permission);
        }
    }
    if (!listPermissionsNeeded.isEmpty()) {
        ActivityCompat.requestPermissions(activity, listPermissionsNeeded.toArray(new String[listPermissionsNeeded.size()]), REQUEST_ID_MULTIPLE_PERMISSIONS);
    }
}

public void onRequestPermissionsResult(Activity activity, int requestCode, String permissions[], int[] grantResults) {
    switch (requestCode) {
        case REQUEST_ID_MULTIPLE_PERMISSIONS: {
            Map<String, Integer> perms = new HashMap<>();

            for (String permission : permissions) {
                perms.put(permission, PackageManager.PERMISSION_GRANTED);
            }

            if (grantResults.length > 0) {
                for (int i = 0; i < permissions.length; i++)
                    perms.put(permissions[i], grantResults[i]);

                boolean allPermissionsGranted = true;
                for (String permission1 : permissions) {
                    allPermissionsGranted = allPermissionsGranted && (perms.get(permission1) == PackageManager.PERMISSION_GRANTED);
                }

                if (allPermissionsGranted) {
                    Log.d(PermissionsHelper.class.getSimpleName(), "onRequestPermissionsResult: all permissions granted");
                } else {
                    for (String permission2 : perms.keySet())
                        if (perms.get(permission2) == PackageManager.PERMISSION_GRANTED)
                            perms.remove(permission2);

                    StringBuilder message = new StringBuilder("The app has not been granted permissions:\n\n");
                    for (String permission : perms.keySet()) {
                        message.append(permission);
                        message.append("\n");
                    }
                    message.append("\nHence, it cannot function properly." +
                            "\nPlease consider granting it this permission in phone Settings.");

                    AlertDialog.Builder builder = new AlertDialog.Builder(activity);
                    builder.setTitle(R.string.permission_required)
                            .setMessage(message)
                            .setPositiveButton(android.R.string.ok, (dialog, id) -> dialog.cancel());
                    AlertDialog alert = builder.create();
                    alert.show();
                }
            }
        }
    }
}

}

If one or several required permissions have not been granted by user, the detailed AlertDialog message will be shown to him.

Example of usage in Activity:

private PermissionsHelper permissionsHelper;

@Override
protected void onCreate(@Nullable Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    checkPermissions();

    //any other code
}

@Override
public void onRequestPermissionsResult(int requestCode, @NonNull String[] permissions, @NonNull int[] grantResults) {
    permissionsHelper.onRequestPermissionsResult(this, requestCode, permissions, grantResults);
}

private void checkPermissions() {
    permissionsHelper = new PermissionsHelper();
    permissionsHelper.checkAndRequestPermissions(this,
            Manifest.permission.READ_EXTERNAL_STORAGE,
            Manifest.permission.ACCESS_FINE_LOCATION,
            Manifest.permission.ACCESS_COARSE_LOCATION);
}

Hope that this will be useful for someone.

To connect from the localhost you need to add '--net host':

docker run --name some-postgres --net host -e POSTGRES_PASSWORD=mysecretpassword -d -p 5432:5432 postgres

You can access the server directly without using exec from your localhost, by using:

psql -h localhost -p 5432 -U postgres

try this

getData(){
    if(window.innerWidth <= 768) {
      alert('mobile view')
      return;
    }

   //else function will work

    let body= {
      "key" : 'keyValue'
    }
    this.dataService.getData(body).subscribe(
      (data: any) => {
        this.myData = data
      }
    )
}

Multiple box shadows did it for me.

box-shadow:
        inset 0 -8px 4px 4px rgb(255,255,255),
        inset 0 2px 4px 0px rgba(50, 50, 50, 0.75);

http://jsfiddle.net/kk66f/

this will work:

$  mongoimport --db databaseName --collection collectionName --file filePath/jsonFile.json 


2021-01-09T11:13:57.410+0530    connected to: mongodb://localhost/
2021-01-09T11:13:58.176+0530    1 document(s) imported successfully. 0 document(s) failed to import.

Above I shared the query along with its response

I'm adding this answer as a use case and complete example for the runtime-check described in another answer.

This is the approach I've been taking for conveying to the end-user whether the program was compiled as 64-bit or 32-bit (or other, for that matter):

version.h

#ifndef MY_VERSION
#define MY_VERSION

#include <string>

const std::string version = "0.09";
const std::string arch = (std::to_string(sizeof(void*) * 8) + "-bit");

#endif

test.cc

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

int main()
{
    std::cerr << "My App v" << version << " [" << arch << "]" << std::endl;
}

Compile and Test

g++ -g test.cc
./a.out
My App v0.09 [64-bit]

Below is a fully functional example of what I believe you're trying to do (with a functional snippet).

Explanation

Based on your question, you seem to be modifying 1 property in state for all of your elements. That's why when you click on one, all of them are being changed.

In particular, notice that the state tracks an index of which element is active. When MyClickable is clicked, it tells the Container its index, Container updates the state, and subsequently the isActive property of the appropriate MyClickables.

Example

class Container extends React.Component {_x000D_
  state = {_x000D_
    activeIndex: null_x000D_
  }_x000D_
_x000D_
  handleClick = (index) => this.setState({ activeIndex: index })_x000D_
_x000D_
  render() {_x000D_
    return <div>_x000D_
      <MyClickable name="a" index={0} isActive={ this.state.activeIndex===0 } onClick={ this.handleClick } />_x000D_
      <MyClickable name="b" index={1} isActive={ this.state.activeIndex===1 } onClick={ this.handleClick }/>_x000D_
      <MyClickable name="c" index={2} isActive={ this.state.activeIndex===2 } onClick={ this.handleClick }/>_x000D_
    </div>_x000D_
  }_x000D_
}_x000D_
_x000D_
class MyClickable extends React.Component {_x000D_
  handleClick = () => this.props.onClick(this.props.index)_x000D_
  _x000D_
  render() {_x000D_
    return <button_x000D_
      type='button'_x000D_
      className={_x000D_
        this.props.isActive ? 'active' : 'album'_x000D_
      }_x000D_
      onClick={ this.handleClick }_x000D_
    >_x000D_
      <span>{ this.props.name }</span>_x000D_
    </button>_x000D_
  }_x000D_
}_x000D_
_x000D_
ReactDOM.render(<Container />, document.getElementById('app'))

button {_x000D_
  display: block;_x000D_
  margin-bottom: 1em;_x000D_
}_x000D_
_x000D_
.album>span:after {_x000D_
  content: ' (an album)';_x000D_
}_x000D_
_x000D_
.active {_x000D_
  font-weight: bold;_x000D_
}_x000D_
_x000D_
.active>span:after {_x000D_
  content: ' ACTIVE';_x000D_
}

<script src="https://cdnjs.cloudflare.com/ajax/libs/react/15.6.1/react-dom.min.js"></script>_x000D_
<div id="app"></div>

Update: "Loops"

In response to a comment about a "loop" version, I believe the question is about rendering an array of MyClickable elements. We won't use a loop, but map, which is typical in React + JSX. The following should give you the same result as above, but it works with an array of elements.

// New render method for `Container`
render() {
  const clickables = [
    { name: "a" },
    { name: "b" },
    { name: "c" },
  ]

  return <div>
      { clickables.map(function(clickable, i) {
          return <MyClickable key={ clickable.name }
            name={ clickable.name }
            index={ i }
            isActive={ this.state.activeIndex === i }
            onClick={ this.handleClick }
          />
        } )
      }
  </div>
}

In order to manually show the modal pop up you have to do this

$('#myModal').modal('show');

You previously need to initialize it with show: false so it won't show until you manually do it.

$('#myModal').modal({ show: false})

Where myModal is the id of the modal container.

For a quick fix to your problem, change your ; to a comma , and eliminate the spaces between email addresses

<a href='mailto:[email protected],[email protected]'>Email Us</a>

Pretty much the same way that you always have, with "Modules" instead of classes and just use "Public" instead of the old "Global" keyword:

Public Module Module1
    Public Foo As Integer
End Module

If you are not sharing your repo with others, this is useful to push all your branches to the remote, and --set-upstream tracking correctly for you:

git push --all -u

(Not exactly what the OP was asking for, but this one-liner is pretty popular)

If you are sharing your repo with others this isn't really good form as you will clog up the repo with all your dodgy experimental branches.

As everyone has pointed out, you'll do this by setting a float:right; on the RHS content and a negative margin on the LHS.

However.. if you don't use a float: left; on the LHS (as Mohit does) then you'll get a stepping effect because the LHS div is still going to consume the margin'd space in layout.

However.. the LHS float will shrink-wrap the content, so you'll need to insert a defined width childnode if that's not acceptable, at which point you may as well have defined the width on the parent.

However.. as David points out you can change the read-order of the markup to avoid the LHS float requirement, but that's has readability and possibly accessibility issues.

However.. this problem can be solved with floats given some additional markup

(caveat: I don't approve of the .clearing div at that example, see here for details)

All things considered, I think most of us wish there was a non-greedy width:remaining in CSS3...

len(repr(float(x)/3))

However I must say that this isn't as reliable as you think.

Floats are entered/displayed as decimal numbers, but your computer (in fact, your standard C library) stores them as binary. You get some side effects from this transition:

>>> print len(repr(0.1))
19
>>> print repr(0.1)
0.10000000000000001

The explanation on why this happens is in this chapter of the python tutorial.

A solution would be to use a type that specifically tracks decimal numbers, like python's decimal.Decimal:

>>> print len(str(decimal.Decimal('0.1')))

Add extension Function:

extension UIImageView {
    func setImage(named: String, color: UIColor) {
        self.image = #imageLiteral(resourceName: named).withRenderingMode(.alwaysTemplate)
        self.tintColor = color
    }
}

Use like:

anyImageView.setImage(named: "image_name", color: .red)

You will have to manually delete from the project explorer (your local machine hard drive), then delete the project in IntelliJ when it asks to re-open recent projects.

Use head:

dnow <- data.frame(x=rnorm(100), y=runif(100))
head(dnow,4) ## default is 6

The :: is called scope resolution operator. Can be used like this:

:: identifier
class-name :: identifier
namespace :: identifier

You can read about it here

I have written Python bindings for libssh2. Libssh2 is a client-side library implementing the SSH2 protocol.

import socket
import libssh2

sock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
sock.connect(('exmaple.com', 22))

session = libssh2.Session()
session.startup(sock)
session.userauth_password('john', '******')

channel = session.channel()
channel.execute('ls -l')

print channel.read(1024)

The proper way to set and get the value of a form field is using .val() method.

$('#field').val('test'); // Set
var value = $('#field').val(); // Get

With jQuery 1.6 there is a new method called .prop().

As of jQuery 1.6, the .attr() method returns undefined for attributes that have not been set. In addition, .attr() should not be used on plain objects, arrays, the window, or the document. To retrieve and change DOM properties, use the .prop() method.

In the introduction of Bootstrap it states which imports you need to add. https://getbootstrap.com/docs/4.0/getting-started/introduction/#quick-start

You have to add some scripts in order to get bootstrap fully working. It's important that you include them in this exact order. Popper.js is one of them:

    <script src="https://code.jquery.com/jquery-3.2.1.slim.min.js" integrity="sha384-KJ3o2DKtIkvYIK3UENzmM7KCkRr/rE9/Qpg6aAZGJwFDMVNA/GpGFF93hXpG5KkN" crossorigin="anonymous"></script>
    <script src="https://cdnjs.cloudflare.com/ajax/libs/popper.js/1.11.0/umd/popper.min.js" integrity="sha384-b/U6ypiBEHpOf/4+1nzFpr53nxSS+GLCkfwBdFNTxtclqqenISfwAzpKaMNFNmj4" crossorigin="anonymous"></script>

In your AppDelegate, in the didRegisterForRemoteNotificationsWithDeviceToken method:

Updated for Swift:

func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
    print("\(deviceToken.reduce("") { $0 + String(format: "%02.2hhx", arguments: [$1]) })")
}

From http://www.epochconverter.com/

SELECT DATEDIFF(s, '1970-01-01 00:00:00', GETUTCDATE())

My bad, SELECT unix_timestamp(time) Time format: YYYY-MM-DD HH:MM:SS or YYMMDD or YYYYMMDD. More on using timestamps with MySQL:

Vanilla JS solutions with complexity of O(n) (fastest possible for this problem). Modify the hashFunction to distinguish the objects (e.g. 1 and "1") if needed. The first solution avoids hidden loops (common in functions provided by Array).

var dedupe = function(a) 
{
    var hash={},ret=[];
    var hashFunction = function(v) { return ""+v; };
    var collect = function(h)
    {
        if(hash.hasOwnProperty(hashFunction(h)) == false) // O(1)
        {
            hash[hashFunction(h)]=1;
            ret.push(h); // should be O(1) for Arrays
            return;
        }
    };

    for(var i=0; i<a.length; i++) // this is a loop: O(n)
        collect(a[i]);
    //OR: a.forEach(collect); // this is a loop: O(n)

    return ret;
}

var dedupe = function(a) 
{
    var hash={};
    var isdupe = function(h)
    {
        if(hash.hasOwnProperty(h) == false) // O(1)
        {
            hash[h]=1;
            return true;
        }

        return false;
    };

    return a.filter(isdupe); // this is a loop: O(n)
}

FWIW, I stumbled over this very same problem (and my boss too, so it got more intense).

The instant solution is to delete or fix your Git entries in the Windows Credential Manager. You may have a hard time finding it in your localized Windows version, but luckily you can start it from the good old Windows + R run dialog with control keymgr.dll or control /name Microsoft.CredentialManager (or rundll32.exe keymgr.dll, KRShowKeyMgr if you prefer the classic look). Or put this in a batch file for your colleagues: cmdkey /delete:git:http://your.git.server.company.com.

In Microsoft's Git Credential Manager this is a known issue that may be fixed as soon as early 2019 (so don't hold your breath).

Update (2020-09-30): GCM4W seems to be more or less abandoned (last release more than a year ago, only one commit to master since then named, I kid you not, "Recreate the scalable version of the GCM Logo"). But don't despair, with Microsoft now going Core, there is a shiny new project called GCM Core, which seems to handle password changes correctly. It can be installed standalone (should be activated automatically, otherwise activate e.g. with git config --system credential.helper manager-core) but is also included in the current Git for Windows 2.28.0. For more information about it, see this blog post.

I just give it a shot:

In [9]: s = Series([True, True, True, False])

In [10]: s
Out[10]: 
0     True
1     True
2     True
3    False

In [11]: -s
Out[11]: 
0    False
1    False
2    False
3     True

You could use the ref prop to acquire a reference to the underlying HTMLInputElement object through a callback, store the reference as a class property, then use that reference to later trigger a click from your event handlers using the HTMLElement.click method.

In your render method:

<input ref={input => this.inputElement = input} ... />

In your event handler:

this.inputElement.click();

Full example:

class MyComponent extends React.Component {
  render() {
    return (
      <div onClick={this.handleClick}>
        <input ref={input => this.inputElement = input} />
      </div>
    );
  }

  handleClick = (e) => {
    this.inputElement.click();
  }
}

Note the ES6 arrow function that provides the correct lexical scope for this in the callback. Also note, that the object you acquire this way is an object akin to what you would acquire using document.getElementById, i.e. the actual DOM-node.

If path is not hardcoded in any script then your websites should work seamlessly.

The accepted answer above is great if you are loading the image based on a button click, however if you are doing it in a new activity it freezes up the UI for a second or two. Looking around I found that a simple asynctask eliminated this problem.

To use an asynctask to add this class at the end of your activity:

private class DownloadImageTask extends AsyncTask<String, Void, Bitmap> {
  ImageView bmImage;

  public DownloadImageTask(ImageView bmImage) {
      this.bmImage = bmImage;
  }

  protected Bitmap doInBackground(String... urls) {
      String urldisplay = urls[0];
      Bitmap mIcon11 = null;
      try {
        InputStream in = new java.net.URL(urldisplay).openStream();
        mIcon11 = BitmapFactory.decodeStream(in);
      } catch (Exception e) {
          Log.e("Error", e.getMessage());
          e.printStackTrace();
      }
      return mIcon11;
  }

  protected void onPostExecute(Bitmap result) {
      bmImage.setImageBitmap(result);
  }
}

And call from your onCreate() method using:

new DownloadImageTask((ImageView) findViewById(R.id.imageView1))
        .execute(MY_URL_STRING);

Dont forget to add below permission in your manifest file

<uses-permission android:name="android.permission.INTERNET"/>

Works great for me. :)

Cause: A trigger was attempted to be retrieved for execution and was found to be invalid. This also means that compilation/authorization failed for the trigger.

Action: Options are to resolve the compilation/authorization errors, disable the trigger, or drop the trigger.

Syntax

ALTER TRIGGER trigger Name DISABLE;

ALTER TRIGGER trigger_Name ENABLE;

There are mainly three types of variables in MySQL:

1. User-defined variables (prefixed with @):

   You can access any user-defined variable without declaring it or initializing it. If you refer to a variable that has not been initialized, it has a value of NULL and a type of string.

   SELECT @var_any_var_name
   

   You can initialize a variable using SET or SELECT statement:

   SET @start = 1, @finish = 10;    
   

   or

   SELECT @start := 1, @finish := 10;
   
   SELECT * FROM places WHERE place BETWEEN @start AND @finish;
   

   User variables can be assigned a value from a limited set of data types: integer, decimal, floating-point, binary or nonbinary string, or NULL value.

   User-defined variables are session-specific. That is, a user variable defined by one client cannot be seen or used by other clients.

   They can be used in SELECT queries using Advanced MySQL user variable techniques.

2. Local Variables (no prefix) :

   Local variables needs to be declared using DECLARE before accessing it.

   They can be used as local variables and the input parameters inside a stored procedure:

   DELIMITER //
   
   CREATE PROCEDURE sp_test(var1 INT) 
   BEGIN   
       DECLARE start  INT unsigned DEFAULT 1;  
       DECLARE finish INT unsigned DEFAULT 10;
   
       SELECT  var1, start, finish;
   
       SELECT * FROM places WHERE place BETWEEN start AND finish; 
   END; //
   
   DELIMITER ;
   
   CALL sp_test(5);
   

   If the DEFAULT clause is missing, the initial value is NULL.

   The scope of a local variable is the BEGIN ... END block within which it is declared.

3. Server System Variables (prefixed with @@):

   The MySQL server maintains many system variables configured to a default value. They can be of type GLOBAL, SESSION or BOTH.

   Global variables affect the overall operation of the server whereas session variables affect its operation for individual client connections.

   To see the current values used by a running server, use the SHOW VARIABLES statement or SELECT @@var_name.

   SHOW VARIABLES LIKE '%wait_timeout%';
   
   SELECT @@sort_buffer_size;
   

   They can be set at server startup using options on the command line or in an option file. Most of them can be changed dynamically while the server is running using SET GLOBAL or SET SESSION:

   -- Syntax to Set value to a Global variable:
   SET GLOBAL sort_buffer_size=1000000;
   SET @@global.sort_buffer_size=1000000;
   
   -- Syntax to Set value to a Session variable:
   SET sort_buffer_size=1000000;
   SET SESSION sort_buffer_size=1000000;
   SET @@sort_buffer_size=1000000;
   SET @@local.sort_buffer_size=10000;
   

In the command line type service apache2 status then hit enter. The result should say:

Apache2 is running (pid xxxx)

If the response is not to be consumed, then the request can be aborted using the code below:

// Low level resources should be released before initiating a new request
HttpEntity entity = response.getEntity();

if (entity != null) {
    // Do not need the rest
    httpPost.abort();
}

Apache HttpClient Version: 4.1.3

The app can't be run natively, but it could be run on an emulator. You can use ManyMo to embed them in a website and make users add your app to their home screen. This link should be useful for making the app more realistic. Users could then only press the share button and add the app to their home screen. All data will be deleted when the "app" is closed in their iOS devices so you should use the Internet/cloud for storage. It can't access camera or multi touch, but it may be useful.

This solution is similar to the one from sroy, but with css triangle instead of web font:

The other answers are correct. However, a quick note: if you're looking to grab the stuff after the ? in a URI, you should use the $_GET[] array.

I went through this post and everything didnt want to work correctly and eventually pieced the bits together from a few answers so I have a 100% working demo and will paste it here for reference - paste this into a php file and make sure includes are in the right place.

I take it that is a Vista Window! I often got this when first trying to port a DirectX program from XPsp3 to Vista.

It's a .dll problem. The OpenCV runtime.dll will call upon a system.dll that will be no longer shipped Vista, so unfortunately you will have to to a bit of hunting to find which system.dll it's trying to find. (system.dll could be vc2010 or vista)

This error is also caused by incorrect installation of .dlls (i.e not rolling out) hth Happy hunting

You could try mixing Number() and toFixed().

Have your target number converted to a nice string with X digits then convert the formated string to a number.

Number( (myVar).toFixed(2) )

See example below:

var myNumber = 5.01;_x000D_
var multiplier = 5;_x000D_
$('#actionButton').on('click', function() {_x000D_
  $('#message').text( myNumber * multiplier );_x000D_
});_x000D_
_x000D_
$('#actionButton2').on('click', function() {_x000D_
  $('#message').text( Number( (myNumber * multiplier).toFixed(2) ) );_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.4.1/jquery.min.js"></script>_x000D_

way too late for the party here but i will still add my $0.02, Google has released a free sample called universal music player with which you can learn to stream music across all android platforms(auto, watch,mobile,tv..) it uses service to play music in the background, do check it out very helpful. here's the link to the project

There is a file in your git root directory named .gitignore. It's a file, not a command. You just need to insert the names of the files that you want to ignore, and they will automatically be ignored. For example, if you wanted to ignore all emacs autosave files, which end in ~, then you could add this line:

*~

If you want to remove the unwanted files from your branch, you can use git add -A, which "removes files that are no longer in the working tree".

Note: What I called the "git root directory" is simply the directory in which you used git init for the first time. It is also where you can find the .git directory.

Add flag “-fno-objc-arc”.

Simple follow steps : App>Targets>Build Phases>Compile Sources> add flag after class “-fno-objc-arc”

For me the issue was caused by the lack of a Primary Key to my table, after setting a PK for the table the problem was gone

I like Jake's solution. The problem with no header is resolved by doing the following

xlWorkSheet.Cells[1, 1] = "Header 1";
xlWorkSheet.Cells[1, 2] = "Header 2";
xlWorkSheet.Cells[1, 3] = "Header 3";

of course this only works is you know what the headers should be ahead of time.

Option 1 Each div is specifically identified, so any other div (without the specific IDs) on the page will not obey the :hover pseudo-class.

<style type="text/css">
  #div1, #div2, #div3{  
    display:none;  
  }  
  #div1:hover, #div2:hover, #div3:hover{  
    display:block;  
  }
</style>

Option 2 All divs on the page, regardless of IDs, have the hover effect.

<style type="text/css">
  div{  
    display:none;  
  }  
  div:hover{  
    display:block;  
  }
</style>

Signing indicates you really are the source or vouch for of the object signed. Everyone can read the object, though.

Encrypting means only those with the corresponding private key can read it, but without signing there is no guarantee you are behind the encrypted object.

Once you write a generic FuncEqualityComparer you can use it everywhere.

peopleList2.Except(peopleList1, new FuncEqualityComparer<Person>((p, q) => p.ID == q.ID));

public class FuncEqualityComparer<T> : IEqualityComparer<T>
{
    private readonly Func<T, T, bool> comparer;
    private readonly Func<T, int> hash;

    public FuncEqualityComparer(Func<T, T, bool> comparer)
    {
        this.comparer = comparer;
        if (typeof(T).GetMethod(nameof(object.GetHashCode)).DeclaringType == typeof(object))
            hash = (_) => 0;
        else
            hash = t => t.GetHashCode(); 
    }

    public bool Equals(T x, T y) => comparer(x, y);
    public int GetHashCode(T obj) => hash(obj);
}

This is due to the interfering messages that come on to the page. There are multiple frames on the page which communicate with the page using window message event and object. few of them can be third party services like cookieq for managing cookies, or may be cartwire an e-com integration service.

You need to handle the onmessage event to check from where the messages are coming, and then parse the JSON accordingly.

I faced a similar problem, where one of the integration was passing a JSON object and other was passing a string starting with u

And the ed answer:

printf "%s\n" '1,$s/STRING_TO_REPLACE/STRING_TO_REPLACE_IT/g' w q | ed index.html

To reiterate what codaddict answered, the shell handles the redirection first, wiping out the "input.html" file, and then the shell invokes the "sed" command passing it a now empty file.

I had the same problem after I used the .gitignore file from https://github.com/github/gitignore/blob/master/Rails.gitignore

Everything worked out fine after I commented the following lines in the .gitignore file.

config/initializers/secret_token.rb
config/secrets.yml

Use this:

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

A race condition occurs when two or more threads can access shared data and they try to change it at the same time. Because the thread scheduling algorithm can swap between threads at any time, you don't know the order in which the threads will attempt to access the shared data. Therefore, the result of the change in data is dependent on the thread scheduling algorithm, i.e. both threads are "racing" to access/change the data.

Problems often occur when one thread does a "check-then-act" (e.g. "check" if the value is X, then "act" to do something that depends on the value being X) and another thread does something to the value in between the "check" and the "act". E.g:

if (x == 5) // The "Check"
{
   y = x * 2; // The "Act"

   // If another thread changed x in between "if (x == 5)" and "y = x * 2" above,
   // y will not be equal to 10.
}

The point being, y could be 10, or it could be anything, depending on whether another thread changed x in between the check and act. You have no real way of knowing.

In order to prevent race conditions from occurring, you would typically put a lock around the shared data to ensure only one thread can access the data at a time. This would mean something like this:

// Obtain lock for x
if (x == 5)
{
   y = x * 2; // Now, nothing can change x until the lock is released. 
              // Therefore y = 10
}
// release lock for x

I will show visually the problem, using the great example from James answer and adding the alternative solution.

When you do the follow query, without the FETCH:

Select e from Employee e 
join e.phones p 
where p.areaCode = '613'

You will have the follow results from Employee as you expected:

But when you add the FETCH word on JOIN, this is what happens:

The generated SQL is the same for the two queries, but the Hibernate removes on memory the 416 register when you use WHERE on the FETCH join.

So, to bring all phones and apply the WHERE correctly, you need to have two JOINs: one for the WHERE and another for the FETCH. Like:

Select e from Employee e 
join e.phones p 
join fetch e.phones      //no alias, to not commit the mistake
where p.areaCode = '613'

I had just duplicated an existing scheme and added another configuration to the project. I had to add a configuration with the same name to the framework's project in order for it to also build in the same DerivedData/($AppName)/Build/Products/($CONFIGURATION_NAME) folder. Otherwise the .framework file doesn't get created and therefore can't be imported.

2 ways

First one we pass the event in the argument right into the onClick.

  onTestClick(e) {
    e.preventDefault();
    alert('here');
  }

  // Look here we pass the args in the onClick
  <Button color="primary" onClick={e => this.onTestClick(e)}>primary</Button>&nbsp;

Second one we pass it into argument and we did right in the onClick

  onTestClick() {
    alert('here');
  }

  // Here we did right inside the onClick, but this is the best way
  <Button color="primary" onClick={e => (e.preventDefault(), this.onTestClick())}>primary</Button>&nbsp;

Hope that can help

Number (2) is possible by using a socket implementation (like websocket, socket.io, etc.) with a custom heartbeat for each session the user is engaged in. If a user attempts to open another window, you have a javascript handler check with the server if it's ok, and then respond with an error messages.

However, a better solution is to synchronize the two sessions if possible like in google docs.

I use a jQuery script to create "shadow" forms for my POSTable links.

Instead of <a href="/some/action?foo=bar">, I write <a data-post="/some/action" data-var-foo="bar" href="#do_action_foo_bar">. The script makes a hidden form with hidden inputs, and submits it when the link is clicked.

$("a[data-post]")
    .each(function() {
        let href = $(this).data("post"); if (!href) return;
        let $form = $("<form></form>").attr({ method:"POST",action:href }).css("display","none")
        let data = $(this).data()
        for (let dat in data) {
            if (dat.startsWith("postVar")) {
                let varname = dat.substring(7).toLowerCase()  // postVarId -> id
                let varval = data[dat]
                $form.append($("<input/>").attr({ type:"hidden",name:varname,value:varval }))
            }
        }
        $("body").append($form)
        $(this).data("postform",$form)
    })
    .click(function(ev) {
        ev.preventDefault()
        if ($(this).data("postform")) $(this).data("postform").submit(); else console.error("No .postform set in <a data-post>")
    })

Internet Explorer doesn't fully support Flexbox due to:

Partial support is due to large amount of bugs present (see known issues).

_{Screenshot and infos taken from caniuse.com}

Notes

Internet Explorer before 10 doesn't support Flexbox, while IE 11 only supports the 2012 syntax.

Known issues

• IE 11 requires a unit to be added to the third argument, the flex-basis property see MSFT documentation.
• In IE10 and IE11, containers with display: flex and flex-direction: column will not properly calculate their flexed childrens' sizes if the container has min-height but no explicit height property. See bug.
• In IE10 the default value for flex is 0 0 auto rather than 0 1 auto as defined in the latest spec.
• IE 11 does not vertically align items correctly when min-height is used. See bug.

Workarounds

Flexbugs is a community-curated list of Flexbox issues and cross-browser workarounds for them. Here's a list of all the bugs with a workaround available and the browsers that affect.

1. Minimum content sizing of flex items not honored
2. Column flex items set to align-items: center overflow their container
3. min-height on a flex container won't apply to its flex items
4. flex shorthand declarations with unitless flex-basis values are ignored
5. Column flex items don't always preserve intrinsic aspect ratios
6. The default flex value has changed
7. flex-basis doesn't account for box-sizing: border-box
8. flex-basis doesn't support calc()
9. Some HTML elements can't be flex containers
10. align-items: baseline doesn't work with nested flex containers
11. Min and max size declarations are ignored when wrapping flex items
12. Inline elements are not treated as flex-items
13. Importance is ignored on flex-basis when using flex shorthand
14. Shrink-to-fit containers with flex-flow: column wrap do not contain their items
15. Column flex items ignore margin: auto on the cross axis
16. flex-basis cannot be animated
17. Flex items are not correctly justified when max-width is used

I don't really think that any of the past answers spotted out the problem of the original poster. They all presume a GET request while the poster was trying to POST data and get a download in response.

In the course of searching for any better answer we found this jQuery Plugin for Requesting Ajax-like File Downloads.

In its "heart" it creates a "temporary" HTML form containing the given data as input fields. This form is appended to the document and posted to the desired URL. Right after that the form is removed again:

jQuery('<form action="'+ url +'" method="'+ (method||'post') +'">'+inputs+'</form>')
    .appendTo('body').submit().remove()

Update Mayur's answer looks pretty promising and very simple in comparison to the jQuery plug-in I referred to.

Another alternate method if you wish to just have look and feel of pop over. Following is the method. Offcourse this is a manual thing, but nicely workable :)

HTML - button

<button class="btn btn-info btn-small" style="margin-right:5px;" id="bg" data-placement='bottom' rel="tooltip" title="Background Image"><i class="icon-picture icon-white"></i></button>

HTML - popover

<div class="bgform popover fade bottom in">
            <div class="arrow"></div>
             ..... your code here .......
</div>

JS

$("#bg").click(function(){
        $('.bgform').slideToggle();
});

Using alpha 28, I accomplished programmatically subscribing to event emitters by way of the eventEmitter.toRx().subscribe(..) method. As it is not intuitive, it may perhaps change in a future release.

This happens when you index a row/column with a number that is larger than the dimensions of your dataframe. For instance, getting the eleventh column when you have only three.

import pandas as pd

df = pd.DataFrame({'Name': ['Mark', 'Laura', 'Adam', 'Roger', 'Anna'],
                   'City': ['Lisbon', 'Montreal', 'Lisbon', 'Berlin', 'Glasgow'],
                   'Car': ['Tesla', 'Audi', 'Porsche', 'Ford', 'Honda']})

You have 5 rows and three columns:

    Name      City      Car
0   Mark    Lisbon    Tesla
1  Laura  Montreal     Audi
2   Adam    Lisbon  Porsche
3  Roger    Berlin     Ford
4   Anna   Glasgow    Honda

Let's try to index the eleventh column (it doesn't exist):

df.iloc[:, 10] # there is obviously no 11th column

IndexError: single positional indexer is out-of-bounds

If you are a beginner with Python, remember that df.iloc[:, 10] would refer to the eleventh column.

Just installed MongoDB via Homebrew. At the end of the installation console, you can see an output as follows:

To start mongodb:

brew services start mongodb

Or, if you don't want/need a background service you can just run:

mongod --config /usr/local/etc/mongod.conf

So, brew services start mongodb, managed to run MongoDB as a service for me.

I was also facing the same problem for twitter-bootstrap.

As eternicode/bootstrap-datepicker is incompatible with jQuery UI.

But twitter-bootstrap is working fine for vitalets/bootstrap-datepicker even with jQuery UI.

Get Selected Checkboxes Value Using jQuery

Then we write jQuery script to get selected checkbox value in an array using jQuery each(). Using this jQuery function it runs a loop to get the checked value and put it into an array.

                });
                alert("My location themes colors are: " + locationthemes.join(", "));

In my case git push was trying to push more that just the current branch, therefore, I got this error since the other branches were not in sync.

To fix that you could use: git config --global push.default simple That will make git to only push the current branch.

This will only work on more recent versions of git. i.e.: won't work on 1.7.9.5

Disclaimer: NOT AN ANSWER TO THE PROBLEM.

Leaving an Important note here:

If you are trying to forceupdate a stateless component, chances are there is something wrong with your design.

Consider the following cases:

1. Pass a setter (setState) to a child component that can change state and cause the parent component to re-render.
2. Consider lifting state up
3. Consider putting that state in your Redux store, that can automatically force a re-render on connected components.

Try this steps:

1. unplug device
2. adb kill-server
3. adb start-server
4. plug device

You need to allow Allow USB debugging in your device when popup.

Combining a couple of the previous answers, you could try start /b cmd /c foo.exe.

For a trivial example, if you wanted to print out the versions of java/groovy/grails/gradle, you could do this in a batch file:

@start /b cmd /c java -version
@start /b cmd /c gradle -version
@start /b cmd /c groovy -version
@start /b cmd /c grails -version

If you have something like Process Explorer (Sysinternals), you will see a few child cmd.exe processes each with a java process (as per the above commands). The output will print to the screen in whatever order they finish.

start /b :  Start application without creating a new window. The
             application has ^C handling ignored. Unless the application
             enables ^C processing, ^Break is the only way to interrupt
             the application

cmd /c : Carries out the command specified by string and then terminates

The vblank_mode environment variable does the trick. You should then get several hundreds FPS on modern hardware. And you are now able to compare the results with others.

$>   vblank_mode=0 glxgears

Answer for a limited, specific situation: assuming you want to delete the files while maintainig the subfolders tree, you could use a recursive algorithm:

import os

def recursively_remove_files(f):
    if os.path.isfile(f):
        os.unlink(f)
    elif os.path.isdir(f):
        for fi in os.listdir(f):
            recursively_remove_files(os.path.join(f, fi))

recursively_remove_files(my_directory)

Maybe slightly off-topic, but I think many would find it useful

You're right, see 3.1.3. Unicode Strings.

It's been the syntax since Python 2.0.

Python 3 made them redundant, as the default string type is Unicode. Versions 3.0 through 3.2 removed them, but they were re-added in 3.3+ for compatibility with Python 2 to aide the 2 to 3 transition.

To check battery percentage we use BatteryManager, the following method will return battery percentage.

Source Link

public static float getBatteryLevel(Context context, Intent intent) {
    Intent batteryStatus = context.registerReceiver(null,
            new IntentFilter(Intent.ACTION_BATTERY_CHANGED));
    int batteryLevel = -1;
    int batteryScale = 1;
    if (batteryStatus != null) {
        batteryLevel = batteryStatus.getIntExtra(BatteryManager.EXTRA_LEVEL, batteryLevel);
        batteryScale = batteryStatus.getIntExtra(BatteryManager.EXTRA_SCALE, batteryScale);
    }
    return batteryLevel / (float) batteryScale * 100;
}

use now() in any cell. then use that cell as a "dummy" parameter in a function. when now() changes every minute the formula recalculates. example: someFunction(a1,b1,c1) * (cell with now() / cell with now())

If you use Spring Tool Suite, option for Generate Deployment Descriptor Stub is moved under Java EE Tools, so you:

1. Right click on your project
2. Select Java EE Tools
3. Select Generate Deployment Descriptor Stub option

This will create web.xml file inside src/main/webapp/WEB-INF/ folder, and of course remove error from Maven's pom.xml file.

The following should do what you want:

x <- data.frame(X1=sample(c(1:3,NaN), 200, replace=TRUE), X2=sample(c(4:6,NaN), 200, replace=TRUE))
head(x)
x <- replace(x, is.na(x), 0)
head(x)

HttpBasicAuth works for me with smaller changes

1. I use maven dependency

   <dependency>
       <groupId>net.iharder</groupId>
       <artifactId>base64</artifactId>
       <version>2.3.8</version>
   </dependency>
   

2. Smaller change

   String encoding = Base64.encodeBytes ((user + ":" + passwd).getBytes());
   

You are probably trying to create nested directories. Assuming foo does not exist, you will receive no such file or directory error for:

Dir.mkdir 'foo/bar'
# => Errno::ENOENT: No such file or directory - 'foo/bar'

To create nested directories at once, FileUtils is needed:

require 'fileutils'
FileUtils.mkdir_p 'foo/bar'
# => ["foo/bar"]

Edit2: you do not have to use FileUtils, you may do system call (update from @mu is too short comment):

> system 'mkdir', '-p', 'foo/bar' # worse version: system 'mkdir -p "foo/bar"'
=> true

But that seems (at least to me) as worse approach as you are using external 'tool' which may be unavailable on some systems (although I can hardly imagine system without mkdir, but who knows).

This should do it:

f = open('myfile.txt')
first = f.readline()

try this:

import net.sf.json.JSONObject;
import net.sf.json.JSONSerializer;
import org.apache.commons.io.IOUtils; 

    public class JsonParsing {

        public static void main(String[] args) throws Exception {
            InputStream is = 
                    JsonParsing.class.getResourceAsStream( "sample-json.txt");
            String jsonTxt = IOUtils.toString( is );

            JSONObject json = (JSONObject) JSONSerializer.toJSON( jsonTxt );        
            double coolness = json.getDouble( "coolness" );
            int altitude = json.getInt( "altitude" );
            JSONObject pilot = json.getJSONObject("pilot");
            String firstName = pilot.getString("firstName");
            String lastName = pilot.getString("lastName");

            System.out.println( "Coolness: " + coolness );
            System.out.println( "Altitude: " + altitude );
            System.out.println( "Pilot: " + lastName );
        }
    }

and this is your sample-json.txt , should be in json format

{
 'foo':'bar',
 'coolness':2.0,
 'altitude':39000,
 'pilot':
     {
         'firstName':'Buzz',
         'lastName':'Aldrin'
     },
 'mission':'apollo 11'
}

As an application distributor, fpm sounds perfect for your needs. There is an example here which shows how to package an app from source. FPM can produce both deb files and RPM files.

Use parameter substitution:

string=${string// /.}

The best and simple way:

Convert(varchar, {EndTime} - {StartTime}, 108)

Just like Anri noted.

This may help you, also it depends how your CSV file is formated.

1. Open your excel sheet & go to menu Data > Import External Data > Import Data.
2. Choose your CSV file.
3. Original data type: choose Fixed width, then Next.
4. It will autmaticall delimit your columns. then, you may check the splitted columns in Data preview panel.
5. Then Finish & see.

Note: you may also go with Delimited as Original data type. In that case, you need to key-in your delimiting character.

HTH!
