git ls-tree --full-tree -r HEAD and git ls-files return all files at once. For a large project with hundreds or thousands of files, and if you are interested in a particular file/directory, you may find more convenient to explore specific directories. You can do it by obtaining the ID/SHA-1 of the directory that you want to explore and then use git cat-file -p [ID/SHA-1 of directory]. For example:

git cat-file -p 14032aabd85b43a058cfc7025dd4fa9dd325ea97
100644 blob b93a4953fff68df523aa7656497ee339d6026d64    glyphicons-halflings-regular.eot
100644 blob 94fb5490a2ed10b2c69a4a567a4fd2e4f706d841    glyphicons-halflings-regular.svg
100644 blob 1413fc609ab6f21774de0cb7e01360095584f65b    glyphicons-halflings-regular.ttf
100644 blob 9e612858f802245ddcbf59788a0db942224bab35    glyphicons-halflings-regular.woff
100644 blob 64539b54c3751a6d9adb44c8e3a45ba5a73b77f0    glyphicons-halflings-regular.woff2

In the example above, 14032aabd85b43a058cfc7025dd4fa9dd325ea97 is the ID/SHA-1 of the directory that I wanted to explore. In this case, the result was that four files within that directory were being tracked by my Git repo. If the directory had additional files, it would mean those extra files were not being tracked. You can add files using git add <file>... of course.

You can try as below :

declare @list varchar(MAX), @i int
select @i=0, @list ='4,7,12,22,19,'

while( @i < LEN(@list))
begin
    declare @item varchar(MAX)
    SELECT  @item = SUBSTRING(@list,  @i,CHARINDEX(',',@list,@i)-@i)
    select @item

     --do your stuff here with @item 
     exec p_MyInnerProcedure @item 

    set @i = CHARINDEX(',',@list,@i)+1
    if(@i = 0) set @i = LEN(@list) 
end

ALTER TABLE can do multiple table alterations in one statement, but MODIFY COLUMN can only work on one column at a time, so you need to specify MODIFY COLUMN for each column you want to change:

ALTER TABLE webstore.Store
  MODIFY COLUMN ShortName VARCHAR(100),
  MODIFY COLUMN UrlShort VARCHAR(100);

Also, note this warning from the manual:

When you use CHANGE or MODIFY, column_definition must include the data type and all attributes that should apply to the new column, other than index attributes such as PRIMARY KEY or UNIQUE. Attributes present in the original definition but not specified for the new definition are not carried forward.

Just wondering why you are using 2 directives?

It seems like, in this case it would be more straightforward to have a controller as the parent - handle adding the data from your service to its $scope, and pass the model you need from there into your warrantyDirective.

Or for that matter, you could use 0 directives to achieve the same result. (ie. move all functionality out of the separate directives and into a single controller).

It doesn't look like you're doing any explicit DOM transformation here, so in this case, perhaps using 2 directives is overcomplicating things.

Alternatively, have a look at the Angular documentation for directives: http://docs.angularjs.org/guide/directive The very last example at the bottom of the page explains how to wire up dependent directives.

% mysql --user=root mysql

The separate start() and run() methods in the Thread class provide two ways to create threaded programs. The start() method starts the execution of the new thread and calls the run() method. The start() method returns immediately and the new thread normally continues until the run() method returns.

The Thread class' run() method does nothing, so sub-classes should override the method with code to execute in the second thread. If a Thread is instantiated with a Runnable argument, the thread's run() method executes the run() method of the Runnable object in the new thread instead.

Depending on the nature of your threaded program, calling the Thread run() method directly can give the same output as calling via the start() method, but in the latter case the code is actually executed in a new thread.

fgets would work for you. here is very good documentation on this :-
http://www.cplusplus.com/reference/cstdio/fgets/

If you don't want to use fgets, following method will work for you :-

int readline(FILE *f, char *buffer, size_t len)
{
   char c; 
   int i;

   memset(buffer, 0, len);

   for (i = 0; i < len; i++)
   {   
      int c = fgetc(f); 

      if (!feof(f)) 
      {   
         if (c == '\r')
            buffer[i] = 0;
         else if (c == '\n')
         {   
            buffer[i] = 0;

            return i+1;
         }   
         else
            buffer[i] = c; 
      }   
      else
      {   
         //fprintf(stderr, "read_line(): recv returned %d\n", c);
         return -1; 
      }   
   }   

   return -1; 
}

Use transparent background color for the modalbottomsheet and give separate color for box decoration

   showModalBottomSheet(
      backgroundColor: Colors.transparent,
      context: context, builder: (context) {
    return Container(

      decoration: BoxDecoration(
        color: Colors.white,
        borderRadius: BorderRadius.only(
            topLeft:Radius.circular(40) ,
            topRight: Radius.circular(40)
        ),
      ),
      padding: EdgeInsets.symmetric(vertical: 20,horizontal: 60),
      child: Settings_Form(),
    );
  });

I solved this problem with custom annotations. This is my "SkipSerialisation" Annotation class:

@Target (ElementType.FIELD)
public @interface SkipSerialisation {

}

and this is my GsonBuilder:

gsonBuilder.addSerializationExclusionStrategy(new ExclusionStrategy() {

  @Override public boolean shouldSkipField (FieldAttributes f) {

    return f.getAnnotation(SkipSerialisation.class) != null;

  }

  @Override public boolean shouldSkipClass (Class<?> clazz) {

    return false;
  }
});

Example :

public class User implements Serializable {

  public String firstName;

  public String lastName;

  @SkipSerialisation
  public String email;
}

Newer kernels (e.g. the latest Ubuntu kernels) come with the new 'perf' tools (apt-get install linux-tools) AKA perf_events.

These come with classic sampling profilers (man-page) as well as the awesome timechart!

The important thing is that these tools can be system profiling and not just process profiling - they can show the interaction between threads, processes and the kernel and let you understand the scheduling and I/O dependencies between processes.

Also, if you want to add module assets both CSS and JS, you can use the following logic. See how you need to indicate the correct path to getPathOfAlias:

public static function register($file)
{
    $url = Yii::app()->getAssetManager()->publish(
    Yii::getPathOfAlias('application.modules.shop.assets.css'));

    $path = $url . '/' . $file;
    if(strpos($file, 'js') !== false)
        return Yii::app()->clientScript->registerScriptFile($path);
    else if(strpos($file, 'css') !== false)
        return Yii::app()->clientScript->registerCssFile($path);

    return $path;
}

The above code has been taken from GPLed Yii based Webshop app.

$("#slide").animate({width:'toggle'},350);

Assuming that Test is a class with a defined constructor, there's no difference. The latter form makes it a little clearer that Test's constructor is running, but that's about it.

Is this what you are looking for?

types is optional

For end of line use:

git diff --ignore-space-at-eol

Instead of what are you using currently:

git diff -w (--ignore-all-space)

For start of line... you are out of luck if you want a built in solution.

However, if you don't mind getting your hands dirty there's a rather old patch floating out there somewhere that adds support for "--ignore-space-at-sol".

you can write multiple lines in case of different minutes, for example you want to run at 10:01 AM and 2:30 PM

1 10 * * * php -f /var/www/package/index.php controller function

30 14 * * * php -f /var/www/package/index.php controller function

but the following is the best solution for running cron multiple times in a day as minutes are same, you can mention hours like 10,30 .

30 10,14 * * * php -f /var/www/package/index.php controller function

A quick, clean approach using very little JS and CSS padding: http://jsfiddle.net/benjamincharity/ZcTsT/14/

var headerHeight = $('#header').height(),
    footerHeight = $('#footer').height();

$('#content').css({
  'padding-top': headerHeight,
  'padding-bottom': footerHeight
});

The key bits of dynamic programming are "overlapping sub-problems" and "optimal substructure". These properties of a problem mean that an optimal solution is composed of the optimal solutions to its sub-problems. For instance, shortest path problems exhibit optimal substructure. The shortest path from A to C is the shortest path from A to some node B followed by the shortest path from that node B to C.

In greater detail, to solve a shortest-path problem you will:

• find the distances from the starting node to every node touching it (say from A to B and C)
• find the distances from those nodes to the nodes touching them (from B to D and E, and from C to E and F)
• we now know the shortest path from A to E: it is the shortest sum of A-x and x-E for some node x that we have visited (either B or C)
• repeat this process until we reach the final destination node

Because we are working bottom-up, we already have solutions to the sub-problems when it comes time to use them, by memoizing them.

Remember, dynamic programming problems must have both overlapping sub-problems, and optimal substructure. Generating the Fibonacci sequence is not a dynamic programming problem; it utilizes memoization because it has overlapping sub-problems, but it does not have optimal substructure (because there is no optimization problem involved).

Call this function onclick of button

/*pass whatever you want instead of id */
function doConfirm(id) {
    var ok = confirm("Are you sure to Delete?");
    if (ok) {
        if (window.XMLHttpRequest) {
            // code for IE7+, Firefox, Chrome, Opera, Safari
            xmlhttp = new XMLHttpRequest();
        } else {
            // code for IE6, IE5
            xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
        }

        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {
                window.location = "create_dealer.php";
            }
        }

        xmlhttp.open("GET", "delete_dealer.php?id=" + id);
        // file name where delete code is written
        xmlhttp.send();
    }
}

What about using ideviceinfo to get these values? Should be able to install it using brew install ideviceinfo

Then run:

PRODUCT_NAME=$(ideviceinfo --udid $DEVICE_UDID --key ProductName)
PRODUCT_TYPE=$(ideviceinfo --udid $DEVICE_UDID --key ProductType)
PRODUCT_VERSION=$(ideviceinfo --udid $DEVICE_UDID --key ProductVersion)

instanceof

The Left Hand Side (LHS) operand is the actual object being tested to the Right Hand Side (RHS) operand which is the actual constructor of a class. The basic definition is:

Checks the current object and returns true if the object
is of the specified object type.

Here are some good examples and here is an example taken directly from Mozilla's developer site:

var color1 = new String("green");
color1 instanceof String; // returns true
var color2 = "coral"; //no type specified
color2 instanceof String; // returns false (color2 is not a String object)

One thing worth mentioning is instanceof evaluates to true if the object inherits from the classe's prototype:

var p = new Person("Jon");
p instanceof Person

That is p instanceof Person is true since p inherits from Person.prototype.

Per the OP's request

I've added a small example with some sample code and an explanation.

When you declare a variable you give it a specific type.

For instance:

int i;
float f;
Customer c;

The above show you some variables, namely i, f, and c. The types are integer, float and a user defined Customer data type. Types such as the above could be for any language, not just JavaScript. However, with JavaScript when you declare a variable you don't explicitly define a type, var x, x could be a number / string / a user defined data type. So what instanceof does is it checks the object to see if it is of the type specified so from above taking the Customer object we could do:

var c = new Customer();
c instanceof Customer; //Returns true as c is just a customer
c instanceof String; //Returns false as c is not a string, it's a customer silly!

Above we've seen that c was declared with the type Customer. We've new'd it and checked whether it is of type Customer or not. Sure is, it returns true. Then still using the Customer object we check if it is a String. Nope, definitely not a String we newed a Customer object not a String object. In this case, it returns false.

It really is that simple!

In WPF, you can easily do it in this way:

this.button.RaiseEvent(new RoutedEventArgs(Button.ClickEvent));

You can also use list.remove(a[0]) to pop out the first element in the list.

>>>> a=[1,2,3,4,5]
>>>> a.remove(a[0])
>>>> print a
>>>> [2,3,4,5]

If you log the

var options = {
  key: fs.readFileSync('./key.pem', 'utf8'),
  cert: fs.readFileSync('./csr.pem', 'utf8')
};

You might notice there are invalid characters due to improper encoding.

Using the solution showed in this question, System.Windows.Forms.Clipboard.SetText(...), results in the exception:

Current thread must be set to single thread apartment (STA) mode before OLE calls can be made

To prevent this, you can add the attribute:

[STAThread]

to

static void Main(string[] args)

If you want to get

localhost:2806 

from

http://localhost:2806/Pages/ 

then use:

HttpContext.Current.Request.Url.Authority

You could save the results into a temp table, but it would be even better to go directly to the source on master.dbo.sysprocesses.

Here's a query that will return almost the exact same result as sp_who2:

SELECT  spid,
        sp.[status],
        loginame [Login],
        hostname, 
        blocked BlkBy,
        sd.name DBName, 
        cmd Command,
        cpu CPUTime,
        physical_io DiskIO,
        last_batch LastBatch,
        [program_name] ProgramName   
FROM master.dbo.sysprocesses sp 
JOIN master.dbo.sysdatabases sd ON sp.dbid = sd.dbid
ORDER BY spid 

Now you can easily add any ORDER BY or WHERE clauses you like to get meaningful output.

Alternatively, you might consider using Activity Monitor in SSMS (Ctrl + Alt + A) as well

Another handy Reflector add-in that I use is the Dependency Structure Matrix. It's really great to see what classes use what. Plus it's free.

Or use JodaTime:

DateTime lastWeek = new DateTime().minusDays(7);

No functions, no cursors. Try this

with cte as(
select CHAR(65) chr, 65 i 
union all
select CHAR(i+1) chr, i=i+1 from cte
where CHAR(i) <'Z'
)
select * from(
SELECT id, Case when LEN(data)>len(REPLACE(data, chr,'')) then chr+chr end data 
FROM table1, cte) x
where Data is not null

Since Matplotlib isn't able to use the metric system natively, if you want to specify the size of your figure in a reasonable unit of length such as centimeters, you can do the following (code from gns-ank):

def cm2inch(*tupl):
    inch = 2.54
    if isinstance(tupl[0], tuple):
        return tuple(i/inch for i in tupl[0])
    else:
        return tuple(i/inch for i in tupl)

Then you can use:

plt.figure(figsize=cm2inch(21, 29.7))

Alternatively, if your objective is to output directly to a file or stdout, you can use cat:

cat(s1, s2, sep=", ")

Another option might be to merge with strategy ours to the commit before the range and then a 'normal' merge with the last commit of that range (or branch when it is the last one). So suppose only 2345 and 3456 commits of master to be merged into feature branch:

master:
1234
2345
3456
4567

in feature branch:

git merge -s ours 4567
git merge 2345

This is my observation with respect to the Error. I recently Updated the ADT to 22.0.1. I am getting following Error when i imported my previous Projects "E/AndroidRuntime(24807): Caused by: java.lang.ClassNotFoundException: com.sherl.sherlockfragmentsapp.StartActivity in loader dalvik.system.PathClassLoader[/data/app/com.sherl.sherlockfragmentsapp-1.apk]"

Then I changed "Properties->Java Build Path-> Order and Export" in the following manner [Unable to add the Image because of the Forum rules]

1. Android Private Libraries - checked
2. Android 4.2.2 - unchecked
3. Android Dependencies - checked
4. /src - selected
5. /gen - selected

It resolved the issue. Hope this is Help you guys.

I'm not sure if you can alter the original element but how about switch from using the id attr to something else like data-id? Then just read the value of data-id for your hash value and it won't jump.

Start to Create a Pull Request via the git hosting service you're using. If the branch has been fully merged into the base branch, you'll be unable to create the new PR.

You don't need to actually make the pull request, just use the first step where you pick branches.

For example, on GitHub:

There isn't anything to compare

This doesn't use git on the command line, but I often find it's helpful to use the other tools at your disposal with a clear mental model rather than attempt to remember another arcane git command.

There is also a slight difference in the html output for a string data type.

Html.EditorFor:  
<input id="Contact_FirstName" class="text-box single-line" type="text" value="Greg" name="Contact.FirstName">

Html.TextBoxFor:
<input id="Contact_FirstName" type="text" value="Greg" name="Contact.FirstName">

Use the left function:

QString yourString = "This is a string";
QString leftSide = yourString.left(5);
qDebug() << leftSide; // output "This "

Also have a look at mid() if you want more control.

From the command line it would be just:

svn update

(in the directory you've got a copy of a SVN project).

Thanks for all the helpful suggestions. I finally made sure that there are no warnings in my code, but again was getting this warning from sqlite3:

Assuming signed overflow does not occur when assuming that (X - c) <= X is always true

which I fixed by adding the following CFLAG:

-fno-strict-overflow

Add the Library file in project.. Project->right click->Properties->android->Library-> click Add and select the Library Project and give apply and ok.. then, clean the project and run again.. if you want restart the eclipse..

And also, sometimes, need to update Android SDK build tools..

Symfony 3.2.8 (kernel: app, env: dev, debug: true)

The implicit make rule for compiling a C program is

%.o:%.c
    $(CC) $(CPPFLAGS) $(CFLAGS) -c -o $@ $<

where the $() syntax expands the variables. As both CPPFLAGS and CFLAGS are used in the compiler call, which you use to define include paths is a matter of personal taste. For instance if foo.c is a file in the current directory

make foo.o CPPFLAGS="-I/usr/include"
make foo.o CFLAGS="-I/usr/include"

will both call your compiler in exactly the same way, namely

gcc -I/usr/include -c -o foo.o foo.c

The difference between the two comes into play when you have multiple languages which need the same include path, for instance if you have bar.cpp then try

make bar.o CPPFLAGS="-I/usr/include"
make bar.o CFLAGS="-I/usr/include"

then the compilations will be

g++ -I/usr/include -c -o bar.o bar.cpp
g++ -c -o bar.o bar.cpp

as the C++ implicit rule also uses the CPPFLAGS variable.

This difference gives you a good guide for which to use - if you want the flag to be used for all languages put it in CPPFLAGS, if it's for a specific language put it in CFLAGS, CXXFLAGS etc. Examples of the latter type include standard compliance or warning flags - you wouldn't want to pass -std=c99 to your C++ compiler!

You might then end up with something like this in your makefile

CPPFLAGS=-I/usr/include
CFLAGS=-std=c99
CXXFLAGS=-Weffc++

In this answer I am using an example posted by Justin Grammens.

About JSON

JSON stands for JavaScript Object Notation. In JavaScript properties can be referenced both like this object1.name and like this object['name'];. The example from the article uses this bit of JSON.

The Parts
A fan object with email as a key and [email protected] as a value

{
  fan:
    {
      email : '[email protected]'
    }
}

So the object equivalent would be fan.email; or fan['email'];. Both would have the same value of '[email protected]'.

About HttpClient Request

The following is what our author used to make a HttpClient Request. I do not claim to be an expert at all this so if anyone has a better way to word some of the terminology feel free.

public static HttpResponse makeRequest(String path, Map params) throws Exception 
{
    //instantiates httpclient to make request
    DefaultHttpClient httpclient = new DefaultHttpClient();

    //url with the post data
    HttpPost httpost = new HttpPost(path);

    //convert parameters into JSON object
    JSONObject holder = getJsonObjectFromMap(params);

    //passes the results to a string builder/entity
    StringEntity se = new StringEntity(holder.toString());

    //sets the post request as the resulting string
    httpost.setEntity(se);
    //sets a request header so the page receving the request
    //will know what to do with it
    httpost.setHeader("Accept", "application/json");
    httpost.setHeader("Content-type", "application/json");

    //Handles what is returned from the page 
    ResponseHandler responseHandler = new BasicResponseHandler();
    return httpclient.execute(httpost, responseHandler);
}

Map

If you are not familiar with the Map data structure please take a look at the Java Map reference. In short, a map is similar to a dictionary or a hash.

private static JSONObject getJsonObjectFromMap(Map params) throws JSONException {

    //all the passed parameters from the post request
    //iterator used to loop through all the parameters
    //passed in the post request
    Iterator iter = params.entrySet().iterator();

    //Stores JSON
    JSONObject holder = new JSONObject();

    //using the earlier example your first entry would get email
    //and the inner while would get the value which would be '[email protected]' 
    //{ fan: { email : '[email protected]' } }

    //While there is another entry
    while (iter.hasNext()) 
    {
        //gets an entry in the params
        Map.Entry pairs = (Map.Entry)iter.next();

        //creates a key for Map
        String key = (String)pairs.getKey();

        //Create a new map
        Map m = (Map)pairs.getValue();   

        //object for storing Json
        JSONObject data = new JSONObject();

        //gets the value
        Iterator iter2 = m.entrySet().iterator();
        while (iter2.hasNext()) 
        {
            Map.Entry pairs2 = (Map.Entry)iter2.next();
            data.put((String)pairs2.getKey(), (String)pairs2.getValue());
        }

        //puts email and '[email protected]'  together in map
        holder.put(key, data);
    }
    return holder;
}

(I will take down if Justin Grammens does not approve. But if not then thanks Justin for being cool about it.)

Update

I just happend to get a comment about how to use the code and realized that there was a mistake in the return type. The method signature was set to return a string but in this case it wasnt returning anything. I changed the signature to HttpResponse and will refer you to this link on Getting Response Body of HttpResponse the path variable is the url and I updated to fix a mistake in the code.

This happens because you use the savedValue in the onCreate() method. The savedValue is updated in onRestoreInstanceState() method, but onRestoreInstanceState() is called after the onCreate() method. You can either:

1. Update the savedValue in onCreate() method, or
2. Move the code that use the new savedValue in onRestoreInstanceState() method.
   

But I suggest you to use the first approach, making the code like this:

public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);

    int display_mode = getResources().getConfiguration().orientation;

    if (display_mode == 1) {

        setContentView(R.layout.main_grid);
        mGrid = (GridView) findViewById(R.id.gridview);
        mGrid.setColumnWidth(95);
        mGrid.setVisibility(0x00000000);
        // mGrid.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);

    } else {
        setContentView(R.layout.main_grid_land);
        mGrid = (GridView) findViewById(R.id.gridview);
        mGrid.setColumnWidth(95);
        Log.d("Mode", "land");
        // mGrid.setSystemUiVisibility(View.SYSTEM_UI_FLAG_LAYOUT_HIDE_NAVIGATION);

    }
    if (savedInstanceState != null) {
        savedUser = savedInstanceState.getString("TEXT");
    } else {
        savedUser = ""
    }
    Log.d("savedUser", savedUser);
    if (savedUser.equals("admin")) { //value 0
        adapter.setApps(appManager.getApplications());
    } else if (savedUser.equals("prof")) { //value 1
        adapter.setApps(appManager.getTeacherApplications());
    } else {// default value
        appManager = new ApplicationManager(this, getPackageManager());
        appManager.loadApplications(true);
        bindApplications();
    }
}

UPDATE: This no longer works in the current version, see below for correct answer (no need to vote down, this is correct on older versions).

Use the JsonTextReader class with a StreamReader or use the JsonSerializer overload that takes a StreamReader directly:

var serializer = new JsonSerializer();
serializer.Deserialize(streamReader);

Or the same thing, with a slightly different (IMO friendlier) syntax:

DELETE FROM posts 
USING posts, projects 
WHERE projects.project_id = posts.project_id AND projects.client_id = :client_id;

BTW, with mysql using joins is almost always a way faster than subqueries...

The imshow() function with parameters interpolation='nearest' and cmap='hot' should do what you want.

import matplotlib.pyplot as plt
import numpy as np

a = np.random.random((16, 16))
plt.imshow(a, cmap='hot', interpolation='nearest')
plt.show()

Its Simple!

Take example of television - it is Encapsulation, because:

1. Television is loaded with different functionalies that i don't know because they are completely hidden.

2. Hidden things like music, video etc everything bundled in a capsule that what we call a TV

Now, Abstraction is When we know a little about something and which can help us to manipulate something for which we don't know how it works internally.

For eg: A remote-control for TV is abstraction, because

1. With remote we know that pressing the number keys will change the channels. We are not aware as to what actually happens internally. We can manipulate the hidden thing but we don't know how it is being done internally.

Programmatically, when we can acess the hidden data somehow and know something.. is Abstraction .. And when we know nothing about the internals its Encapsulation.

Without remote we can't change anything on TV we have to see what it shows coz all controls are hidden.

The built-in string constructor will automatically call obj.__str__:

''.join(map(str,list))

Left Click on chart. «PivotTable Field List» will appear on right. On the right down quarter of PivotTable Field List (S Values), you see the names of the legends. Left Click on the legend name. Left Click on the «Value field settings». At the top there is «Source Name». You can’t change it. Below there is «Custom Name». Change the Custom Name as you wish. Now the legend name on the chart has the new name you gave.

If you work on Linux you can try this:

setwd(system("pwd", intern = T) )

It works for me.

You can check the socket.connected property:

var socket = io.connect();
console.log('check 1', socket.connected);
socket.on('connect', function() {
  console.log('check 2', socket.connected);
});

It's updated dynamically, if the connection is lost it'll be set to false until the client picks up the connection again. So easy to check for with setInterval or something like that.

Another solution would be to catch disconnect events and track the status yourself.

Set the socket non-blocking, and use select() (which takes a timeout parameter). If a non-blocking socket is trying to connect, then select() will indicate that the socket is writeable when the connect() finishes (either successfully or unsuccessfully). You then use getsockopt() to determine the outcome of the connect():

int main(int argc, char **argv) {
    u_short port;                /* user specified port number */
    char *addr;                  /* will be a pointer to the address */
    struct sockaddr_in address;  /* the libc network address data structure */
    short int sock = -1;         /* file descriptor for the network socket */
    fd_set fdset;
    struct timeval tv;

    if (argc != 3) {
        fprintf(stderr, "Usage %s <port_num> <address>\n", argv[0]);
        return EXIT_FAILURE;
    }

    port = atoi(argv[1]);
    addr = argv[2];

    address.sin_family = AF_INET;
    address.sin_addr.s_addr = inet_addr(addr); /* assign the address */
    address.sin_port = htons(port);            /* translate int2port num */

    sock = socket(AF_INET, SOCK_STREAM, 0);
    fcntl(sock, F_SETFL, O_NONBLOCK);

    connect(sock, (struct sockaddr *)&address, sizeof(address));

    FD_ZERO(&fdset);
    FD_SET(sock, &fdset);
    tv.tv_sec = 10;             /* 10 second timeout */
    tv.tv_usec = 0;

    if (select(sock + 1, NULL, &fdset, NULL, &tv) == 1)
    {
        int so_error;
        socklen_t len = sizeof so_error;

        getsockopt(sock, SOL_SOCKET, SO_ERROR, &so_error, &len);

        if (so_error == 0) {
            printf("%s:%d is open\n", addr, port);
        }
    }

    close(sock);
    return 0;
}

Here, very sweet and small solution:

1) create a store procedure:

create procedure get_table
@find_str varchar(50)
as 
begin
  declare @col_name varchar(500), @tab_name varchar(500);
  declare @find_tab TABLE(table_name varchar(100), column_name varchar(100));

  DECLARE tab_col cursor for 
  select C.name as 'col_name', T.name as tab_name
  from sys.tables as T
  left outer join sys.columns as C on  C.object_id=T.object_id
  left outer join sys.types as TP on  C.system_type_id=TP.system_type_id
  where type='U' 
  and TP.name in('text','ntext','varchar','char','nvarchar','nchar');

  open tab_col
  fetch next from tab_col into @col_name, @tab_name

  while @@FETCH_STATUS = 0
  begin        
    insert into @find_tab 
    exec('select ''' +  @tab_name + ''',''' + @col_name + ''' from ' + @tab_name + 
    ' where ' + @col_name + '=''' + @find_str + ''' group by ' + 
    @col_name + ' having count(*)>0');

    fetch next from tab_col into @col_name, @tab_name;
  end
  CLOSE tab_col;  
  DEALLOCATE tab_col; 
  select table_name, column_name from @find_tab;

end

==========================

2) call procedure by calling store procedure:
exec get_table 'serach_string';

Dim strFirstAddress As String
Dim searchlast As Range
Dim search As Range

Set search = ActiveSheet.Range("A1:A100")
Set searchlast = search.Cells(search.Cells.Count)

Set rngFindValue = ActiveSheet.Range("A1:A100").Find(Text, searchlast, xlValues)
If Not rngFindValue Is Nothing Then
  strFirstAddress = rngFindValue.Address
  Do
    Set rngFindValue = search.FindNext(rngFindValue)
  Loop Until rngFindValue.Address = strFirstAddress

Pandas merge offers a naive, fast solution to the problem:

# given the lists
x, y, z = [1, 2, 3], [4, 5], [6, 7]

# get dfs with same, constant index 
x = pd.DataFrame({'x': x}, index=np.repeat(0, len(x))
y = pd.DataFrame({'y': y}, index=np.repeat(0, len(y))
z = pd.DataFrame({'z': z}, index=np.repeat(0, len(z))

# get all permutations stored in a new df
df = pd.merge(x, pd.merge(y, z, left_index=True, righ_index=True),
              left_index=True, right_index=True)

Adding a quick cheat sheet that may help after the long break with Angular:

DECLARATIONS

Example:

declarations: [AppComponent]

What can we inject here? Components, pipes, directives

IMPORTS

Example:

imports: [BrowserModule, AppRoutingModule]

What can we inject here? other modules

PROVIDERS

Example:

providers: [UserService]

What can we inject here? services

BOOTSTRAP

Example:

bootstrap: [AppComponent]

What can we inject here? the main component that will be generated by this module (top parent node for a component tree)

ENTRY COMPONENTS

Example:

entryComponents: [PopupComponent]

What can we inject here? dynamically generated components (for instance by using ViewContainerRef.createComponent())

EXPORT

Example:

export: [TextDirective, PopupComponent, BrowserModule]

What can we inject here? components, directives, modules or pipes that we would like to have access to them in another module (after importing this module)

You need to modify the jenkins.xml file. Specifically you need to change

   <arguments>-Xrs -Xmx256m 
    -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle 
    -jar "%BASE%\jenkins.war" --httpPort=8080</arguments>

to

    <arguments>-Xrs -Xmx2048m -XX:MaxPermSize=512m 
    -Dhudson.lifecycle=hudson.lifecycle.WindowsServiceLifecycle 
    -jar "%BASE%\jenkins.war" --httpPort=8080</arguments>

You can also verify the Java options that Jenkins is using by installing the Jenkins monitor plugin via Manage Jenkins / Manage Plugins and then navigating to Managing Jenkins / Monitoring of Hudson / Jenkins master to use monitoring to determine how much memory is available to Jenkins.

If you are getting an out of memory error when Jenkins calls Maven, it may be necessary to set MAVEN_OPTS via Manage Jenkins / Configure System e.g. if you are running on a version of Java prior to JDK 1.8 (the values are suggestions):

-Xmx2048m  -XX:MaxPermSize=512m

If you are using JDK 1.8:

-Xmx2048m

Yes. In your login module, just export a single function that takes the db as its argument. For example:

module.exports = function(db) {
  ...
};

Your javascript is executed before the HTML is generated, so it doesn't "see" the ungenerated INPUT elements. For jQuery, you would either stick the Javascript at the end of the HTML or wrap it like this:

<script type="text/javascript">   $(function() { //jQuery trick to say after all the HTML is parsed.     $("input[type=radio]").click(function() {       var total = 0;       $("input[type=radio]:checked").each(function() {         total += parseFloat($(this).val());       });        $("#totalSum").val(total);     });   }); </script> 

EDIT: This code works for me

<!DOCTYPE html> <html> <head> <meta charset="utf-8"> </head> <body>   <strong>Choose a base package:</strong>   <input id="item_0" type="radio" name="pkg" value="1942" />Base Package 1 - $1942   <input id="item_1" type="radio" name="pkg" value="2313" />Base Package 2 - $2313   <input id="item_2" type="radio" name="pkg" value="2829" />Base Package 3 - $2829   <strong>Choose an add on:</strong>   <input id="item_10" type="radio" name="ext" value="0" />No add-on - +$0   <input id="item_12" type="radio" name="ext" value="2146" />Add-on 1 - (+$2146)   <input id="item_13" type="radio" name="ext" value="2455" />Add-on 2 - (+$2455)   <input id="item_14" type="radio" name="ext" value="2764" />Add-on 3 - (+$2764)   <input id="item_15" type="radio" name="ext" value="3073" />Add-on 4 - (+$3073)   <input id="item_16" type="radio" name="ext" value="3382" />Add-on 5 - (+$3382)   <input id="item_17" type="radio" name="ext" value="3691" />Add-on 6 - (+$3691)   <strong>Your total is:</strong>   <input id="totalSum" type="text" name="totalSum" readonly="readonly" size="5" value="" />   <script src="http://ajax.googleapis.com/ajax/libs/jquery/1.10.2/jquery.min.js"></script>   <script type="text/javascript">       $("input[type=radio]").click(function() {         var total = 0;         $("input[type=radio]:checked").each(function() {           total += parseFloat($(this).val());         });          $("#totalSum").val(total);       });     </script> </body> </html> 

If your are using IntelliJ, go to setting => compiler and change the version to your current java version.

(rand() % ($max-$min)) + $min

or

rand ( $min , $max )

http://php.net/manual/en/function.rand.php

See Input and Ouput:

with open('filename') as f:
    lines = f.readlines()

or with stripping the newline character:

with open('filename') as f:
    lines = [line.rstrip() for line in f]

The best and easiest way to check if a variable is empty in PHP is just to use the empty() function.

if empty($variable) then ....

For Mac OS:

#ifdef __APPLE__

For MingW on Windows:

#ifdef __MINGW32__

For Linux:

#ifdef __linux__

For other Windows compilers, check this thread and this for several other compilers and architectures.

A sort of block comment uses an if statement:

if(FALSE) {
  all your code
}

It works, but I almost always use the block comment options of my editors (RStudio, Kate, Kwrite).

Here is my answer in Python 2.7

Print current time with timezone

from datetime import datetime
import tzlocal  # pip install tzlocal

print datetime.now(tzlocal.get_localzone()).strftime("%Y-%m-%d %H:%M:%S %z")

Print current time with specific timezone

from datetime import datetime
import pytz # pip install pytz

print datetime.now(pytz.timezone('Asia/Taipei')).strftime("%Y-%m-%d %H:%M:%S %z")

It will print something like

2017-08-10 20:46:24 +0800

I can suggest using the rsample package:

# choosing 75% of the data to be the training data
data_split <- initial_split(data, prop = .75)
# extracting training data and test data as two seperate dataframes
data_train <- training(data_split)
data_test  <- testing(data_split)

There are 2 ways to call-

1. setInterval(function (){ functionName();}, 60000);

2. setInterval(functionName, 60000);

above function will call on every 60 seconds.

myArray[j.x] is logically incorrect.

Use (myArray[j].x); instead

for (var j = 0; j < myArray.length; j++){
  console.log(myArray[j].x);
}

I actually wrote a function recently that would check for a substring within an array that will come in handy in this situation.

function strInArray($haystack, $needle) {
    $i = 0;
    foreach ($haystack as $value) {
        $result = stripos($value,$needle);
        if ($result !== FALSE) return TRUE;
        $i++;
    }
    return FALSE;
}

$array = array(12,43,66,21,56,43,43,78,78,100,43,43,43,21);

for ($i = 0; $i < count($array); $i++) {
    if (strInArray($array,$array[$i])) {
        unset($array[$i]);
    }
}
var_dump($array);

sleep(1.0/24.0)

As to your follow up question if that's the best way: No, you could get not-so-smooth framerates because the rendering of each frame might not take the same amount of time.

You could try one of these solutions:

• Use a timer which fires 24 times a second with the drawing code.
• Create as many frames as possible, create the motion based on the time passed, not per frame.

For angular 8 and Firebase 6 you can use the option id field

      getAllDocs() {
           const ref = this.db.collection('items');
           return ref.valueChanges({idField: 'customIdName'});
      }

this adds the Id of the document on the object with a specified key (customIdName)

If you would like to setup the search facility inside your Fragment, just add these few lines:

Step 1 - Add the search field to you toolbar:

<item
    android:id="@+id/action_search"
    android:icon="@android:drawable/ic_menu_search"
    app:showAsAction="always|collapseActionView"
    app:actionViewClass="android.support.v7.widget.SearchView"
    android:title="Search"/>

Step 2 - Add the logic to your onCreateOptionsMenu()

import android.support.v7.widget.SearchView; // not the default !

@Override
public boolean onCreateOptionsMenu( Menu menu) {
    getMenuInflater().inflate( R.menu.main, menu);

    MenuItem myActionMenuItem = menu.findItem( R.id.action_search);
    searchView = (SearchView) myActionMenuItem.getActionView();
    searchView.setOnQueryTextListener(new SearchView.OnQueryTextListener() {
        @Override
        public boolean onQueryTextSubmit(String query) {
            // Toast like print
            UserFeedback.show( "SearchOnQueryTextSubmit: " + query);
            if( ! searchView.isIconified()) {
                searchView.setIconified(true);
            }
            myActionMenuItem.collapseActionView();
            return false;
        }
        @Override
        public boolean onQueryTextChange(String s) {
            // UserFeedback.show( "SearchOnQueryTextChanged: " + s);
            return false;
        }
    });
    return true;
}

The way to keep SELECT dbo.fCalculateEstimateDate(647) call working is:

ALTER function [dbo].[fCalculateEstimateDate] (@vWorkOrderID numeric)
Returns varchar(100)  AS
   Declare @Result varchar(100)
   SELECT @Result = [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID,DEFAULT)
   Return @Result
Begin
End

CREATE function [dbo].[fCalculateEstimateDate_v2] (@vWorkOrderID numeric,@ToDate DateTime=null)
Returns varchar(100)  AS
Begin
  <Function Body>
End

I found a solution that worked in my case:

<input class="form-control" style="min-width: 100%!important;" type="text" />

You only need to override the min-width set 100% and important and the result is this one:

If you don't apply it, you will always get this:

Use chown to change ownership and chmod to change rights.

use the -R option to apply the rights for all files inside of a directory too.

Note that both these commands just work for directories too. The -R option makes them also change the permissions for all files and directories inside of the directory.

For example

sudo chown -R username:group directory

will change ownership (both user and group) of all files and directories inside of directory and directory itself.

sudo chown username:group directory

will only change the permission of the folder directory but will leave the files and folders inside the directory alone.

you need to use sudo to change the ownership from root to yourself.

Edit:

Note that if you use chown user: file (Note the left-out group), it will use the default group for that user.

Also You can change the group ownership of a file or directory with the command:

chgrp group_name file/directory_name

You must be a member of the group to which you are changing ownership to.

You can find group of file as follows

# ls -l file
-rw-r--r-- 1 root family 0 2012-05-22 20:03 file

# chown sujit:friends file

User 500 is just a normal user. Typically user 500 was the first user on the system, recent changes (to /etc/login.defs) has altered the minimum user id to 1000 in many distributions, so typically 1000 is now the first (non root) user.

What you may be seeing is a system which has been upgraded from the old state to the new state and still has some processes knocking about on uid 500. You can likely change it by first checking if your distro should indeed now use 1000, and if so alter the login.defs file yourself, the renumber the user account in /etc/passwd and chown/chgrp all their files, usually in /home/, then reboot.

But in answer to your question, no, you should not really be worried about this in all likelihood. It'll be showing as "500" instead of a username because o user in /etc/passwd has a uid set of 500, that's all.

Also you can show your current numbers using id i'm willing to bet it comes back as 1000 for you.

Try this code

private void clearAppData() {
    try {
        if (Build.VERSION_CODES.KITKAT <= Build.VERSION.SDK_INT) {
            ((ActivityManager)getSystemService(ACTIVITY_SERVICE)).clearApplicationUserData();
        } else {
            Runtime.getRuntime().exec("pm clear " + getApplicationContext().getPackageName());
        }
    } catch (Exception e) {
        e.printStackTrace();
    }
}

const oneDay = 24 * 60 * 60 * 1000; // hours*minutes*seconds*milliseconds
const firstDate = new Date(2008, 1, 12);
const secondDate = new Date(2008, 1, 22);

const diffDays = Math.round(Math.abs((firstDate - secondDate) / oneDay));

This worked for me...

    double num = 10025000;
    new DecimalFormat("#,###.##");
    DecimalFormat df = (DecimalFormat) DecimalFormat.getInstance(Locale.GERMAN);
    System.out.println(df.format(num));

Using axes objects is a great approach for this. It helps if you want to interact with multiple figures and sub-plots. To add and manipulate the axes objects directly:

import matplotlib.pyplot as plt
fig = plt.figure(figsize=(12,9))

signal_axes = fig.add_subplot(211)
signal_axes.plot(xs,rawsignal)

fft_axes = fig.add_subplot(212)
fft_axes.set_title("FFT")
fft_axes.set_autoscaley_on(False)
fft_axes.set_ylim([0,1000])
fft = scipy.fft(rawsignal)
fft_axes.plot(abs(fft))

plt.show()

For the impatient:

UPDATE target AS t
INNER JOIN (
  SELECT s.id, COUNT(*) AS count
  FROM source_grouped AS s
  -- WHERE s.custom_condition IS (true)
  GROUP BY s.id
) AS aggregate ON aggregate.id = t.id
SET t.count = aggregate.count

That's @mellamokb's answer, as above, reduced to the max.

After much pain, and great assistance from @vitr et al above, i decided to try

• standard bash substitution
• shell form of ENTRYPOINT (great tip from above)

and that worked.

ENV LISTEN_PORT=""

ENTRYPOINT java -cp "app:app/lib/*" hello.Application --server.port=${LISTEN_PORT:-80}

e.g.

docker run --rm -p 8080:8080 -d --env LISTEN_PORT=8080 my-image

and

docker run --rm -p 8080:80 -d my-image

both set the port correctly in my container

Seems like the problem is with the date format.

 var d = "17-09-2013 10:08",
 dArr = d.split('-'),
 ts = new Date(dArr[1] + "-" + dArr[0] + "-" + dArr[2]).getTime(); // 1379392680000

Style the ::-ms-clear pseudo-element for the box:

.someinput::-ms-clear {
    display: none;
}

I think you've missed the point of access control.

A quick recap on why CORS exists: Since JS code from a website can execute XHR, that site could potentially send requests to other sites, masquerading as you and exploiting the trust those sites have in you(e.g. if you have logged in, a malicious site could attempt to extract information or execute actions you never wanted) - this is called a CSRF attack. To prevent that, web browsers have very stringent limitations on what XHR you can send - you are generally limited to just your domain, and so on.

Now, sometimes it's useful for a site to allow other sites to contact it - sites that provide APIs or services, like the one you're trying to access, would be prime candidates. CORS was developed to allow site A(e.g. paste.ee) to say "I trust site B, so you can send XHR from it to me". This is specified by site A sending "Access-Control-Allow-Origin" headers in its responses.

In your specific case, it seems that paste.ee doesn't bother to use CORS. Your best bet is to contact the site owner and find out why, if you want to use paste.ee with a browser script. Alternatively, you could try using an extension(those should have higher XHR privileges).

As Vinay Kumar pointed out that it will not update global installed Angular CLI. To update it globally just use following commands:

npm uninstall -g @angular/cli
npm cache clean
npm install -g @angular/cli@latest

Note if you want to update existing project you have to modify existing project, you should change package.json inside your project.

There are no breaking changes in Angular itself but they are in RxJS, so don't forget to use rxjs-compat library to work with legacy code.

  npm install --save rxjs-compat  

I wrote a good article about installation/updating Angular CLI http://bmnteam.com/angular-cli-installation/

You can import svg and it use it like a image

import chatSVG from '../assets/images/undraw_typing_jie3.svg'

And ise it in img tag

<img src={chatSVG} className='iconChat' alt="Icon chat"/>

One way to make sure a method from a class is not called is to override the method with a dummy.

    WebFormCreatorActivity activity = spy(new WebFormCreatorActivity(clientFactory) {//spy(new WebFormCreatorActivity(clientFactory));
            @Override
            public void select(TreeItem i) {
                log.debug("SELECT");
            };
        });

View is a basic building block of UI (User Interface) in android. A view is a small rectangular box which responds to user inputs. Eg: EditText, Button, CheckBox, etc..

ViewGroup is a invisible container of other views (child views) and other viewgroups. Eg: LinearLayout is a viewgroup which can contain other views in it.

ViewGroup is a special kind of view which is extended from View as its base class. ViewGroup is the base class for layouts.

as name states View is singular and the group of Views is the ViewGroup.

There is no way to know that the two members of the options array came from variables named size and color.

They are also not necessarily called that exclusively, any variable could also point to that array.

var notSize = size;

console.log(options[0]); // It is `size` or `notSize`?

One thing you can do is use an object there instead...

var options = {
    size: size,
    color: color
}

Then you could access options.size or options.color.

=VLOOKUP(Left(A1,1),B$2:B$22,2,FALSE)

Left is because you are starting the word/alphanumeric text from the left. the number "1" which i have placed is after lookup value in this case "A1" is because my search includes the formula for 1st character. If second character is asked it would be (A1,2) quite simple really :)

If I am correct H2 is from the same guys who wrote HSQLDB. Its a lot better if you trust the benchmarks on their site. Also, there is some notion that sun community jumped too quickly into Derby.

JPQL mostly is case-insensitive. One of the things that is case-sensitive is Java entity names. Change your query to:

"SELECT r FROM FooBar r"

A solution that is viable for both Linux and Windows is to just get used to using console ffmpeg in your code. I stack up threads, write a simple thread controller class, then you can easily make use of what ever functionality of ffmpeg you want to use.

As an example, this contains sections use ffmpeg to create a thumbnail from a time that I specify.

In the thread controller you have something like

List<ThrdFfmpeg> threads = new List<ThrdFfmpeg>();

Which is the list of threads that you are running, I make use of a timer to Pole these threads, you can also set up an event if Pole'ing is not suitable for your application. In this case thw class Thrdffmpeg contains,

public class ThrdFfmpeg
{
    public FfmpegStuff ffm { get; set; }
    public Thread thrd { get; set; }
}

FFmpegStuff contains the various ffmpeg functionality, thrd is obviously the thread.

A property in FfmpegStuff is the class FilesToProcess, which is used to pass information to the called process, and receive information once the thread has stopped.

public class FileToProcess
{
    public int videoID { get; set; }
    public string fname { get; set; }
    public int durationSeconds { get; set; }
    public List<string> imgFiles { get; set; }
}

VideoID (I use a database) tells the threaded process which video to use taken from the database. fname is used in other parts of my functions that use FilesToProcess, but not used here. durationSeconds - is filled in by the threads that just collect video duration. imgFiles is used to return any thumbnails that were created.

I do not want to get bogged down in my code when the purpose of this is to encourage the use of ffmpeg in easily controlled threads.

Now we have our pieces we can add to our threads list, so in our controller we do something like,

        AddThread()
        {
        ThrdFfmpeg thrd;
        FileToProcess ftp;

        foreach(FileToProcess ff in  `dbhelper.GetFileNames(txtCategory.Text))`
        {
            //make a thread for each
            ftp = new FileToProcess();
            ftp = ff;
            ftp.imgFiles = new List<string>();
            thrd = new ThrdFfmpeg();
            thrd.ffm = new FfmpegStuff();
            thrd.ffm.filetoprocess = ftp;
            thrd.thrd = new   `System.Threading.Thread(thrd.ffm.CollectVideoLength);`

         threads.Add(thrd);
        }
        if(timerNotStarted)
             StartThreadTimer();
        }

Now Pole'ing our threads becomes a simple task,

private void timerThreads_Tick(object sender, EventArgs e)
    {
        int runningCount = 0;
        int finishedThreads = 0;
        foreach(ThrdFfmpeg thrd in threads)
        {
            switch (thrd.thrd.ThreadState)
            {
                case System.Threading.ThreadState.Running:
                    ++runningCount;


 //Note that you can still view data progress here,
    //but remember that you must use your safety checks
    //here more than anywhere else in your code, make sure the data
    //is readable and of the right sort, before you read it.
                    break;
                case System.Threading.ThreadState.StopRequested:
                    break;
                case System.Threading.ThreadState.SuspendRequested:
                    break;
                case System.Threading.ThreadState.Background:
                    break;
                case System.Threading.ThreadState.Unstarted:


//Any threads that have been added but not yet started, start now
                    thrd.thrd.Start();
                    ++runningCount;
                    break;
                case System.Threading.ThreadState.Stopped:
                    ++finishedThreads;


//You can now safely read the results, in this case the
   //data contained in FilesToProcess
   //Such as
                    ThumbnailsReadyEvent( thrd.ffm );
                    break;
                case System.Threading.ThreadState.WaitSleepJoin:
                    break;
                case System.Threading.ThreadState.Suspended:
                    break;
                case System.Threading.ThreadState.AbortRequested:
                    break;
                case System.Threading.ThreadState.Aborted:
                    break;
                default:
                    break;
            }
        }


        if(flash)
        {//just a simple indicator so that I can see
         //that at least one thread is still running
            lbThreadStatus.BackColor = Color.White;
            flash = false;
        }
        else
        {
            lbThreadStatus.BackColor = this.BackColor;
            flash = true;
        }
        if(finishedThreads >= threads.Count())
        {

            StopThreadTimer();
            ShowSample();
            MakeJoinedThumb();
        }
    }

Putting your own events onto into the controller class works well, but in video work, when my own code is not actually doing any of the video file processing, poling then invoking an event in the controlling class works just as well.

Using this method I have slowly built up just about every video and stills function I think I will ever use, all contained in the one class, and that class as a text file is useable on the Lunux and Windows version, with just a small number of pre-process directives.

List<String> lsColumns = new List<string>();

if(dt.Rows.Count>0)
{
    var count = dt.Rows[0].Table.Columns.Count;

    for (int i = 0; i < count;i++ )
    {
        lsColumns.Add(Convert.ToString(dt.Rows[0][i]));
    }
}

This question is a duplicate of Force "Internet Explorer 8" browser mode in intranet.

The responses there indicate that it's not possible to disable the compatibility view (on the server side) - https://stackoverflow.com/a/4130343/24267. That certainly seems to be the case, as none of the suggestions I've tried have worked. In IE8 the "Browser Mode" gets set to Internet Explorer 8 Compatibility view no matter what kind of X-UA-Compatible header you send.

I had to do some special handling for IE7 and compatibility mode, which caused the browser to render using IE8 but report it was IE7, broke my code. This is how I fixed my code (I am aware this is a horrible hack and I should be testing for features not browser versions):

isIE8 = navigator.appVersion.indexOf("MSIE") != -1 && parseFloat(navigator.appVersion.split("MSIE")[1]) == 8;
if (!isIE8 && navigator.appVersion.indexOf("MSIE") != -1 && parseFloat(navigator.appVersion.split("MSIE")[1]) == 7 && navigator.appVersion.indexOf("Trident") != -1) {
    // Liar, this is IE8 in compatibility mode.
    isIE8 = true;
}

This small function always comes in handy.

public static String join(String[] strings, int startIndex, String separator) {
    StringBuffer sb = new StringBuffer();
    for (int i=startIndex; i < strings.length; i++) {
        if (i != startIndex) sb.append(separator);
        sb.append(strings[i]);
    }
    return sb.toString();
}

$hash_type$salt$password

If the hash does not use a salt, then there is no $ sign for that. The actual hash in your case is after the 2nd $

The reason for this is, so you can have many types of hashes with different salts and feeds that string into a function that knows how to match it with some other value.

You're missing #include <stdlib.h>.

var string = 123 (is string),

parseInt(parameter is string);

var string = '123';

var int= parseInt(string );

console.log(int);  //Output will be 123.

"How can I directly (without saving the file on 2nd server) download the file from 1st server to client's machine?"

Just use the Client API and get the InputStream from the response

Client client = ClientBuilder.newClient();
String url = "...";
final InputStream responseStream = client.target(url).request().get(InputStream.class);

There are two flavors to get the InputStream. You can also use

Response response = client.target(url).request().get();
InputStream is = (InputStream)response.getEntity();

Which one is the more efficient? I'm not sure, but the returned InputStreams are different classes, so you may want to look into that if you care to.

From 2nd server I can get a ByteArrayOutputStream to get the file from 1st server, can I pass this stream further to the client using the REST service?

So most of the answers you'll see in the link provided by @GradyGCooper seem to favor the use of StreamingOutput. An example implementation might be something like

final InputStream responseStream = client.target(url).request().get(InputStream.class);
System.out.println(responseStream.getClass());
StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) throws IOException, WebApplicationException {  
        int length;
        byte[] buffer = new byte[1024];
        while((length = responseStream.read(buffer)) != -1) {
            out.write(buffer, 0, length);
        }
        out.flush();
        responseStream.close();
    }   
};
return Response.ok(output).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

But if we look at the source code for StreamingOutputProvider, you'll see in the writeTo, that it simply writes the data from one stream to another. So with our implementation above, we have to write twice.

How can we get only one write? Simple return the InputStream as the Response

final InputStream responseStream = client.target(url).request().get(InputStream.class);
return Response.ok(responseStream).header(
        "Content-Disposition", "attachment, filename=\"...\"").build();

If we look at the source code for InputStreamProvider, it simply delegates to ReadWriter.writeTo(in, out), which simply does what we did above in the StreamingOutput implementation

 public static void writeTo(InputStream in, OutputStream out) throws IOException {
    int read;
    final byte[] data = new byte[BUFFER_SIZE];
    while ((read = in.read(data)) != -1) {
        out.write(data, 0, read);
    }
}

Asides:

• Client objects are expensive resources. You may want to reuse the same Client for request. You can extract a WebTarget from the client for each request.

  WebTarget target = client.target(url);
  InputStream is = target.request().get(InputStream.class);
  

  I think the WebTarget can even be shared. I can't find anything in the Jersey 2.x documentation (only because it is a larger document, and I'm too lazy to scan through it right now :-), but in the Jersey 1.x documentation, it says the Client and WebResource (which is equivalent to WebTarget in 2.x) can be shared between threads. So I'm guessing Jersey 2.x would be the same. but you may want to confirm for yourself.

• You don't have to make use of the Client API. A download can be easily achieved with the java.net package APIs. But since you're already using Jersey, it doesn't hurt to use its APIs

• The above is assuming Jersey 2.x. For Jersey 1.x, a simple Google search should get you a bunch of hits for working with the API (or the documentation I linked to above)

UPDATE

I'm such a dufus. While the OP and I are contemplating ways to turn a ByteArrayOutputStream to an InputStream, I missed the simplest solution, which is simply to write a MessageBodyWriter for the ByteArrayOutputStream

import java.io.ByteArrayOutputStream;
import java.io.IOException;
import java.io.OutputStream;
import java.lang.annotation.Annotation;
import java.lang.reflect.Type;
import javax.ws.rs.WebApplicationException;
import javax.ws.rs.core.MediaType;
import javax.ws.rs.core.MultivaluedMap;
import javax.ws.rs.ext.MessageBodyWriter;
import javax.ws.rs.ext.Provider;

@Provider
public class OutputStreamWriter implements MessageBodyWriter<ByteArrayOutputStream> {

    @Override
    public boolean isWriteable(Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return ByteArrayOutputStream.class == type;
    }

    @Override
    public long getSize(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType) {
        return -1;
    }

    @Override
    public void writeTo(ByteArrayOutputStream t, Class<?> type, Type genericType,
            Annotation[] annotations, MediaType mediaType,
            MultivaluedMap<String, Object> httpHeaders, OutputStream entityStream)
            throws IOException, WebApplicationException {
        t.writeTo(entityStream);
    }
}

Then we can simply return the ByteArrayOutputStream in the response

return Response.ok(baos).build();

D'OH!

UPDATE 2

Here are the tests I used (

Resource class

@Path("test")
public class TestResource {

    final String path = "some_150_mb_file";

    @GET
    @Produces(MediaType.APPLICATION_OCTET_STREAM)
    public Response doTest() throws Exception {
        InputStream is = new FileInputStream(path);
        ByteArrayOutputStream baos = new ByteArrayOutputStream();
        int len;
        byte[] buffer = new byte[4096];
        while ((len = is.read(buffer, 0, buffer.length)) != -1) {
            baos.write(buffer, 0, len);
        }
        System.out.println("Server size: " + baos.size());
        return Response.ok(baos).build();
    }
}

Client test

public class Main {
    public static void main(String[] args) throws Exception {
        Client client = ClientBuilder.newClient();
        String url = "http://localhost:8080/api/test";
        Response response = client.target(url).request().get();
        String location = "some_location";
        FileOutputStream out = new FileOutputStream(location);
        InputStream is = (InputStream)response.getEntity();
        int len = 0;
        byte[] buffer = new byte[4096];
        while((len = is.read(buffer)) != -1) {
            out.write(buffer, 0, len);
        }
        out.flush();
        out.close();
        is.close();
    }
}

UPDATE 3

So the final solution for this particular use case was for the OP to simply pass the OutputStream from the StreamingOutput's write method. Seems the third-party API, required a OutputStream as an argument.

StreamingOutput output = new StreamingOutput() {
    @Override
    public void write(OutputStream out) {
        thirdPartyApi.downloadFile(.., .., .., out);
    }
}
return Response.ok(output).build();

Not quite sure, but seems the reading/writing within the resource method, using ByteArrayOutputStream`, realized something into memory.

The point of the downloadFile method accepting an OutputStream is so that it can write the result directly to the OutputStream provided. For instance a FileOutputStream, if you wrote it to file, while the download is coming in, it would get directly streamed to the file.

It's not meant for us to keep a reference to the OutputStream, as you were trying to do with the baos, which is where the memory realization comes in.

So with the way that works, we are writing directly to the response stream provided for us. The method write doesn't actually get called until the writeTo method (in the MessageBodyWriter), where the OutputStream is passed to it.

You can get a better picture looking at the MessageBodyWriter I wrote. Basically in the writeTo method, replace the ByteArrayOutputStream with StreamingOutput, then inside the method, call streamingOutput.write(entityStream). You can see the link I provided in the earlier part of the answer, where I link to the StreamingOutputProvider. This is exactly what happens

Functional requirements are those which are related to the technical functionality of the system.

non-functional requirement is a requirement that specifies criteria that can be used to judge the operation of a system in particular conditions, rather than specific behaviors.

For example if you consider a shopping site, adding items to cart, browsing different items, applying offers and deals and successfully placing orders comes under functional requirements.

Where as performance of the system in peak hours, time taken for the system to retrieve data from DB, security of the user data, ability of the system to handle if large number of users login comes under non functional requirements.

The dplyr select function selects specific columns from a data frame. To return unique values in a particular column of data, you can use the group_by function. For example:

library(dplyr)

# Fake data
set.seed(5)
dat = data.frame(x=sample(1:10,100, replace=TRUE))

# Return the distinct values of x
dat %>%
  group_by(x) %>%
  summarise() 

    x
1   1
2   2
3   3
4   4
5   5
6   6
7   7
8   8
9   9
10 10

If you want to change the column name you can add the following:

dat %>%
  group_by(x) %>%
  summarise() %>%
  select(unique.x=x)

This both selects column x from among all the columns in the data frame that dplyr returns (and of course there's only one column in this case) and changes its name to unique.x.

You can also get the unique values directly in base R with unique(dat$x).

If you have multiple variables and want all unique combinations that appear in the data, you can generalize the above code as follows:

set.seed(5)
dat = data.frame(x=sample(1:10,100, replace=TRUE), 
                 y=sample(letters[1:5], 100, replace=TRUE))

dat %>% 
  group_by(x,y) %>%
  summarise() %>%
  select(unique.x=x, unique.y=y)

Catching an exception while using a Python 'with' statement

The with statement has been available without the __future__ import since Python 2.6. You can get it as early as Python 2.5 (but at this point it's time to upgrade!) with:

from __future__ import with_statement

Here's the closest thing to correct that you have. You're almost there, but with doesn't have an except clause:

with open("a.txt") as f: 
    print(f.readlines())
except:                    # <- with doesn't have an except clause.
    print('oops')

A context manager's __exit__ method, if it returns False will reraise the error when it finishes. If it returns True, it will suppress it. The open builtin's __exit__ doesn't return True, so you just need to nest it in a try, except block:

try:
    with open("a.txt") as f:
        print(f.readlines())
except Exception as error: 
    print('oops')

And standard boilerplate: don't use a bare except: which catches BaseException and every other possible exception and warning. Be at least as specific as Exception, and for this error, perhaps catch IOError. Only catch errors you're prepared to handle.

So in this case, you'd do:

>>> try:
...     with open("a.txt") as f:
...         print(f.readlines())
... except IOError as error: 
...     print('oops')
... 
oops

I had this issue in conjunction with the LNK2038 error, followed this post to segregate the RELEASE and the DEBUG DLLs. In this process I had cleaned up the whole folder where these dependencies were residing.

Luckily I had a backup of all these files, and got the file for which this error was throwing back into the DEBUG folder to resolve the issue. The error code was misleading in some way as I had to spend a lot of time to come to this tip from one of the answers from this post again.

Hope this answer, helps someone in need.

pip list

List installed packages: show ALL installed packages that even pip installed implictly

pip freeze

List installed packages: - list of packages that are installed using pip command

pip freeze has --all flag to show all the packages.

Other difference is the output it renders, that you can check by running the commands.

@bcorso has already demonstrated the proof of the complexity analysis. But for the sake of those still learning complexity analysis, I have this to add:

The basis of your original mistake is due to a misinterpretation of the meaning of the statement, "insertion into a heap takes O(log n) time". Insertion into a heap is indeed O(log n), but you have to recognise that n is the size of the heap during the insertion.

In the context of inserting n objects into a heap, the complexity of the ith insertion is O(log n_i) where n_i is the size of the heap as at insertion i. Only the last insertion has a complexity of O (log n).

This may be obvious, but you can inline the array like so:

package main

import (
    "fmt"
)

func main() {
    for _, element := range [3]string{"a", "b", "c"} {
        fmt.Print(element)
    }
}

outputs:

abc

As mentioned multiprocessing pool is much slower than basic threading. Using queues as proposeded in some answers here is a very effective alternative. I have use it with dictionaries in order to be able run a lot of small threads and recuperate multiple answers by combining them with dictionaries:

#!/usr/bin/env python3

import threading
# use Queue for python2
import queue
import random

LETTERS = 'abcdefghijklmnopqrstuvwxyz'
LETTERS = [ x for x in LETTERS ]

NUMBERS = [0, 1, 2, 3, 4, 5, 6, 7, 8, 9]

def randoms(k, q):
    result = dict()
    result['letter'] = random.choice(LETTERS)
    result['number'] = random.choice(NUMBERS)
    q.put({k: result})

threads = list()
q = queue.Queue()
results = dict()

for name in ('alpha', 'oscar', 'yankee',):
    threads.append( threading.Thread(target=randoms, args=(name, q)) )
    threads[-1].start()
_ = [ t.join() for t in threads ]
while not q.empty():
    results.update(q.get())

print(results)

Sounds like the "...and I jump line by line..." part is wrong. Do you StepOver or StepIn and are you sure you don't accidentally miss the relevant call?

That said, debugging frameworks can be tedious for exactly this reason. To alleviate the problem, you can enable the "Enable frameworks debugging support" experiment. Happy debugging! :)

It just doesn't.

The best way to fix this is:

sign = lambda x: bool(x > 0) - bool(x < 0)

If you want to align center on left attribute.
The same thing is for top alignment, you could use margin-top: (width/2 of your div), the concept is the same of left attribute.
It's important to set header element to position:relative.
try this:

#logo {
    background:red;
    height:50px;
    position:absolute;
    width:50px;
    left:50%;
    margin-left:-25px;
}

DEMO

If you would like to not use calculations you can do this:

#logo {
  background:red;
  width:50px;
  height:50px;
  position:absolute;
  left: 0;
  right: 0;
  margin: 0 auto;
}

Easy way to do:

NSInteger value = x;
NSString *string = [@(value) stringValue];

Here the @(value) converts the given NSInteger to an NSNumber object for which you can call the required function, stringValue.

-Xmn : the size of the heap for the young generation Young generation represents all the objects which have a short life of time. Young generation objects are in a specific location into the heap, where the garbage collector will pass often. All new objects are created into the young generation region (called "eden"). When an object survive is still "alive" after more than 2-3 gc cleaning, then it will be swap has an "old generation" : they are "survivor" .

I read comments on answer set as Okay. Most of the user are asking that the button and some links click should be allowed. Here one more line is added to the existing code that will work.

<script type="text/javascript">
  var hook = true;
  window.onbeforeunload = function() {
    if (hook) {

      return "Did you save your stuff?"
    }
  }
  function unhook() {
    hook=false;
  }

Call unhook() onClick for button and links which you want to allow. E.g.

<a href="#" onClick="unhook()">This link will allow navigation</a>

This should show all files modified within the last 7 days.

Pipe that into tar/zip, and you should be good.

If you want to get all unique values without any approximation or setting a magic number (size: 500), then use COMPOSITE AGGREGATION (ES 6.5+).

From official documentation:

"If you want to retrieve all terms or all combinations of terms in a nested terms aggregation you should use the COMPOSITE AGGREGATION which allows to paginate over all possible terms rather than setting a size greater than the cardinality of the field in the terms aggregation. The terms aggregation is meant to return the top terms and does not allow pagination."

Implementation example in JavaScript:

const ITEMS_PER_PAGE = 1000;_x000D_
_x000D_
const body =  {_x000D_
    "size": 0, // Returning only aggregation results: https://www.elastic.co/guide/en/elasticsearch/reference/current/returning-only-agg-results.html_x000D_
    "aggs" : {_x000D_
        "langs": {_x000D_
            "composite" : {_x000D_
                "size": ITEMS_PER_PAGE,_x000D_
                "sources" : [_x000D_
                    { "language": { "terms" : { "field": "language" } } }_x000D_
                ]_x000D_
            }_x000D_
        }_x000D_
     }_x000D_
};_x000D_
_x000D_
const uniqueLanguages = [];_x000D_
_x000D_
while (true) {_x000D_
  const result = await es.search(body);_x000D_
_x000D_
  const currentUniqueLangs = result.aggregations.langs.buckets.map(bucket => bucket.key);_x000D_
_x000D_
  uniqueLanguages.push(...currentUniqueLangs);_x000D_
_x000D_
  const after = result.aggregations.langs.after_key;_x000D_
_x000D_
  if (after) {_x000D_
      // continue paginating unique items_x000D_
      body.aggs.langs.composite.after = after;_x000D_
  } else {_x000D_
      break;_x000D_
  }_x000D_

_x000D_
console.log(uniqueLanguages);

using Eloquent

$data = array(
    array('user_id'=>'Coder 1', 'subject_id'=> 4096),
    array('user_id'=>'Coder 2', 'subject_id'=> 2048),
    //...
);

Model::insert($data);

file_name=test.log

# set first K lines:
K=1000

# line count (N): 
N=$(wc -l < $file_name)

# length of the bottom file:
L=$(( $N - $K ))

# create the top of file: 
head -n $K $file_name > top_$file_name

# create bottom of file: 
tail -n $L $file_name > bottom_$file_name

Also, on second thought, split will work in your case, since the first split is larger than the second. Split puts the balance of the input into the last split, so

split -l 300000 file_name

will output xaa with 300k lines and xab with 100k lines, for an input with 400k lines.

I know this doesn't really answer your question, but different View Engines have different purposes. The Spark View Engine, for example, aims to rid your views of "tag soup" by trying to make everything fluent and readable.

Your best bet would be to just look at some implementations. If it looks appealing to the intent of your solution, try it out. You can mix and match view engines in MVC, so it shouldn't be an issue if you decide to not go with a specific engine.

You should just use something like:

YourModel.update_all(
  ActiveRecord::Base.send(:sanitize_sql_for_assignment, {:value => "'wow'"})
)

That would do the trick. Using the ActiveRecord::Base#send method to invoke the sanitize_sql_for_assignment makes the Ruby (at least the 1.8.7 version) skip the fact that the sanitize_sql_for_assignment is actually a protected method.

You should also consider changing some of your rules to:

1. Add more special characters i.e. %, ^, (, ), -, _, +, and period. I'm adding all the special characters that you missed above the number signs in US keyboards. Escape the ones regex uses.
2. Make the password 8 or more characters. Not just a static number 8.

With the above improvements, and for more flexibility and readability, I would modify the regex to.

^(?=(.*[a-z]){3,})(?=(.*[A-Z]){2,})(?=(.*[0-9]){2,})(?=(.*[!@#$%^&*()\-__+.]){1,}).{8,}$

Basic Explanation

(?=(.*RULE){MIN_OCCURANCES,})     

Each rule block is shown by (?=(){}). The rule and number of occurrences can then be easily specified and tested separately, before getting combined

Detailed Explanation

^                               start anchor
(?=(.*[a-z]){3,})               lowercase letters. {3,} indicates that you want 3 of this group
(?=(.*[A-Z]){2,})               uppercase letters. {2,} indicates that you want 2 of this group
(?=(.*[0-9]){2,})               numbers. {2,} indicates that you want 2 of this group
(?=(.*[!@#$%^&*()\-__+.]){1,})  all the special characters in the [] fields. The ones used by regex are escaped by using the \ or the character itself. {1,} is redundant, but good practice, in case you change that to more than 1 in the future. Also keeps all the groups consistent
{8,}                            indicates that you want 8 or more
$                               end anchor

And lastly, for testing purposes here is a robulink with the above regex

git-rebase(1) does exactly that.

$ git rebase -i HEAD~5

git awsome-ness [git rebase --interactive] contains an example.

1. Don't use git-rebase on public (remote) commits.
2. Make sure your working directory is clean (commit or stash your current changes).
3. Run the above command. It launches your $EDITOR.
4. Replace pick before C and D by squash. It will meld C and D into B. If you want to delete a commit then just delete its line.

If you are lost, type:

$ git rebase --abort  

Providing disabled property as true inside FormControl surely disables the input field.

this.form=this.fb.group({
  FirstName:[{value:'first name', disabled:true}],
  LastValue:['last name,[Validators.required]]
})

The above example will disable the FirstName input field.

But real problem arises when you try to access disabled field value through form like this console.log(this.form.value.FirstName); and it shows as undefined instead of printing field's actual value. So, to access disabled field's value, one must use getRawValue() method provided by Reactive Forms. i.e. console.log(this.form.getRawValue().FirstName); would print the actual value of form field and not undefined.

How about (works also for 0 and negatives):

int digits( int x ) { 
    return ( (bool) x * (int) log10( abs( x ) ) + 1 );
}

You can easily do this by:

::variableName.isInitialized

or

this::variableName.isInitialized

But if you are inside a listener or inner class, do this:

this@OuterClassName::variableName.isInitialized

Note: The above statements work fine if you are writing them in the same file(same class or inner class) where the variable is declared but this will not work if you want to check the variable of other class (which could be a superclass or any other class which is instantiated), for ex:

class Test {
    lateinit var str:String
}

And to check if str is initialized:

What we are doing here: checking isInitialized for field str of Test class in Test2 class. And we get an error backing field of var is not accessible at this point. Check a question already raised about this.

You have to close that application first. There is no way to delete it, if it's used by some application.

UnLock IT is a neat utility that helps you to take control of any file or folder when it is locked by some application or system. For every locked resource, you get a list of locking processes and can unlock it by terminating those processes. EMCO Unlock IT offers Windows Explorer integration that allows unlocking files and folders by one click in the context menu.

There's also Unlocker (not recommended, see Warning below), which is a free tool which helps locate any file locking handles running, and give you the option to turn it off. Then you can go ahead and do anything you want with those files.

Warning: The installer includes a lot of undesirable stuff. You're almost certainly better off with UnLock IT.

Here's what worked for me.

Here is another choice: Chaosreader

So I need to debug an application which posts xml to a 3rd party application. I found a brilliant little perl script which does all the hard work – you just chuck it a tcpdump output file, and it does all the manipulation and outputs everything you need...

The script is called chaosreader0.94. See http://www.darknet.org.uk/2007/11/chaosreader-trace-tcpudp-sessions-from-tcpdump/

It worked like a treat, I did the following:

tcpdump host www.blah.com -s 9000 -w outputfile; perl chaosreader0.94 outputfile

Using LINQ to manipulate data in DataSet/DataTable

var results = from myRow in tblCurrentStock.AsEnumerable()
              where myRow.Field<string>("item_name").ToUpper().StartsWith(tbSearchItem.Text.ToUpper())
              select myRow;
DataView view = results.AsDataView();

OK, they all have got some similarities, they do the same things for you in different and similar ways, I divide them in 3 main groups as below:

webpack and browserify as popular ones, work like task runners but with more flexibility, aslo it will bundle everything together as your setting, so you can point to the result as bundle.js for example in one single file including the CSS and Javascript, for more details of each, look at the details below:

webpack

webpack is a module bundler for modern JavaScript applications. When webpack processes your application, it recursively builds a dependency graph that includes every module your application needs, then packages all of those modules into a small number of bundles - often only one - to be loaded by the browser.

It is incredibly configurable, but to get started you only need to understand Four Core Concepts: entry, output, loaders, and plugins.

This document is intended to give a high-level overview of these concepts, while providing links to detailed concept specific use-cases.

more here

browserify

Browserify is a development tool that allows us to write node.js-style modules that compile for use in the browser. Just like node, we write our modules in separate files, exporting external methods and properties using the module.exports and exports variables. We can even require other modules using the require function, and if we omit the relative path it’ll resolve to the module in the node_modules directory.

2) Task runners

gulp and grunt are task runners, basically what they do, creating tasks and run them whenever you want, for example you install a plugin to minify your CSS and then run it each time to do minifying, more details about each:

gulp

gulp.js is an open-source JavaScript toolkit by Fractal Innovations and the open source community at GitHub, used as a streaming build system in front-end web development. It is a task runner built on Node.js and Node Package Manager (npm), used for automation of time-consuming and repetitive tasks involved in web development like minification, concatenation, cache busting, unit testing, linting, optimization etc. gulp uses a code-over-configuration approach to define its tasks and relies on its small, single-purposed plugins to carry them out. gulp ecosystem has 1000+ such plugins made available to choose from.

more here

grunt

Grunt is a JavaScript task runner, a tool used to automatically perform frequently used tasks such as minification, compilation, unit testing, linting, etc. It uses a command-line interface to run custom tasks defined in a file (known as a Gruntfile). Grunt was created by Ben Alman and is written in Node.js. It is distributed via npm. Presently, there are more than five thousand plugins available in the Grunt ecosystem.

3) Package managers

package managers, what they do is managing plugins you need in your application and install them for you through github etc using package.json, very handy to update you modules, install them and sharing your app across, more details for each:

npm

npm is a package manager for the JavaScript programming language. It is the default package manager for the JavaScript runtime environment Node.js. It consists of a command line client, also called npm, and an online database of public packages, called the npm registry. The registry is accessed via the client, and the available packages can be browsed and searched via the npm website.

more here

bower

Bower can manage components that contain HTML, CSS, JavaScript, fonts or even image files. Bower doesn’t concatenate or minify code or do anything else - it just installs the right versions of the packages you need and their dependencies. To get started, Bower works by fetching and installing packages from all over, taking care of hunting, finding, downloading, and saving the stuff you’re looking for. Bower keeps track of these packages in a manifest file, bower.json.

more here

and the most recent package manager that shouldn't be missed, it's young and fast in real work environment compare to npm which I was mostly using before, for reinstalling modules, it do double checks the node_modules folder to check the existence of the module, also seems installing the modules takes less time:

yarn

Yarn is a package manager for your code. It allows you to use and share code with other developers from around the world. Yarn does this quickly, securely, and reliably so you don’t ever have to worry.

Yarn allows you to use other developers’ solutions to different problems, making it easier for you to develop your software. If you have problems, you can report issues or contribute back, and when the problem is fixed, you can use Yarn to keep it all up to date.

Code is shared through something called a package (sometimes referred to as a module). A package contains all the code being shared as well as a package.json file which describes the package.

more here

Empty-ness and "NULL-ness" are two different concepts. As others mentioned the former can be achieved via std::string::empty(), the latter can be achieved with boost::optional<std::string>, e.g.:

boost::optional<string> myStr;
if (myStr) { // myStr != NULL
    // ...
}

There is not really any other way in JavaScript to concatenate strings.
You could theoretically use .concat(), but that's way slower than just +

Libraries are more often than not slower than native JavaScript, especially on basic operations like string concatenation, or numerical operations.

Simply put: + is the fastest.

I had various JDK from 1.5 to 1.7 installed on my PC. I had a need to learn JDK1.8 so installed and my earlier versions of Eclipse (depended on earlier versions of JDK) and I got errors launching my Eclipse IDE, on the command line I tried to check the Java Version and got the error below,

C:\>java -version
Registry key 'Software\JavaSoft\Java Runtime Environment\CurrentVersion'
has value '1.8', but '1.6' is required.
Error: could not find java.dll
Error: could not find Java SE Runtime Environment.

Solution:- I removed

C:\ProgramData\Oracle\Java\javapath;

You can do something like create a record which contains the data you want to authenticate to the application. This could include anything you want - e.g. program features to enable, expiry date, name of the user (if you want to bind it to a user). Then encrypt that using some crypto algorithm with a fixed key or hash it. Then you just verify it within your program. One way to distribute the license file (on windows) is to provide it as a file which updates the registry (saves the user having to type it).

Beware of false sense of security though - sooner or later someone will simply patch your program to skip that check, and distribute the patched version. Or, they will work out a key that passes all checks and distribute that, or backdate the clock, etc. It doesn't matter how convoluted you make your scheme, anything you do for this will ultimately be security through obscurity and they will always be able to this. Even if they can't someone will, and will distribute the hacked version. Same applies even if you supply a dongle - if someone wants to, they can patch out the check for that too. Digitally signing your code won't help, they can remove that signature, or resign it.

You can complicate matters a bit by using techniques to prevent the program running in a debugger etc, but even this is not bullet proof. So you should just make it difficult enough that an honest user will not forget to pay. Also be very careful that your scheme does not become obtrusive to paying users - it's better to have some ripped off copies than for your paying customers not to be able to use what they have paid for.

Another option is to have an online check - just provide the user with a unique ID, and check online as to what capabilities that ID should have, and cache it for some period. All the same caveats apply though - people can get round anything like this.

Consider also the support costs of having to deal with users who have forgotten their key, etc.

edit: I just want to add, don't invest too much time in this or think that somehow your convoluted scheme will be different and uncrackable. It won't, and cannot be as long as people control the hardware and OS your program runs on. Developers have been trying to come up with ever more complex schemes for this, thinking that if they develop their own system for it then it will be known only to them and therefore 'more secure'. But it really is the programming equivalent of trying to build a perpetual motion machine. :-)

Just to confirm though you probably did...

Did you include the

<!--  tell spring to use annotation based congfigurations -->
<context:annotation-config />
<!--  tell spring where to find the beans -->
<context:component-scan base-package="zz.yy.abcd" />

bits in your application context.xml?

Also I'm not so sure you'd be able to use a jta transaction type with this kind of setup? Wouldn't that require a data source managed connection pool? So try RESOURCE_LOCAL instead.

I was facing the same problem yesterday and did not want to add a hidden item to the ArrayAdapter or use reflections, which works fine but is kind of dirty.

After reading many posts and trying around I found a solution by extending ArrayAdapter and Overriding the getView method.

import android.content.Context;
import android.support.annotation.NonNull;
import android.view.LayoutInflater;
import android.view.View;
import android.view.ViewGroup;
import android.widget.ArrayAdapter;
import android.widget.Spinner;
import android.widget.TextView;

/**
 * A SpinnerAdapter which does not show the value of the initial selection initially,
 * but an initialText.
 * To use the spinner with initial selection instead call notifyDataSetChanged().
 */
public class SpinnerAdapterWithInitialText<T> extends ArrayAdapter<T> {

    private Context context;
    private int resource;

    private boolean initialTextWasShown = false;
    private String initialText = "Please select";

    /**
     * Constructor
     *
     * @param context The current context.
     * @param resource The resource ID for a layout file containing a TextView to use when
     *                 instantiating views.
     * @param objects The objects to represent in the ListView.
     */
    public SpinnerAdapterWithInitialText(@NonNull Context context, int resource, @NonNull T[] objects) {
        super(context, resource, objects);
        this.context = context;
        this.resource = resource;
    }

    /**
     * Returns whether the user has selected a spinner item, or if still the initial text is shown.
     * @param spinner The spinner the SpinnerAdapterWithInitialText is assigned to.
     * @return true if the user has selected a spinner item, false if not.
     */
    public boolean selectionMade(Spinner spinner) {
        return !((TextView)spinner.getSelectedView()).getText().toString().equals(initialText);
    }

    /**
     * Returns a TextView with the initialText the first time getView is called.
     * So the Spinner has an initialText which does not represent the selected item.
     * To use the spinner with initial selection instead call notifyDataSetChanged(),
     * after assigning the SpinnerAdapterWithInitialText.
     */
    @Override
    public View getView(int position, View recycle, ViewGroup container) {
        if(initialTextWasShown) {
            return super.getView(position, recycle, container);
        } else {
            initialTextWasShown = true;
            LayoutInflater inflater = LayoutInflater.from(context);
            final View view = inflater.inflate(resource, container, false);

            ((TextView) view).setText(initialText);

            return view;
        }
    }
}

What Android does when initialising the Spinner, is calling getView for the selected item before calling getView for all items in T[] objects. The SpinnerAdapterWithInitialText returns a TextView with the initialText, the first time it is called. All the other times it calls super.getView which is the getView method of ArrayAdapter which is called if you are using the Spinner normally.

To find out whether the user has selected a spinner item, or if the spinner still displays the initialText, call selectionMade and hand over the spinner the adapter is assigned to.

You can also format the string like so:

>>> print ("{index}. {word} appears {count} times".format(index=1, word='Hello', count=42))

Which outputs

1. Hello appears 42 times.

Because the values are named, their order does not matter. Making the example below output the same as the above example.

>>> print ("{index}. {word} appears {count} times".format(count=42, index=1, word='Hello'))

Formatting string this way allows you to do this.

>>> data = {'count':42, 'index':1, 'word':'Hello'}
>>> print ("{index}. {word} appears {count} times.".format(**data))
1. Hello appears 42 times.

Use the Google PHP API Client: https://github.com/google/google-api-php-client

Here's a little mini class just to get YouTube statistics for a single video id. It can obviously be extended a ton using the remainder of the api: https://api.kdyby.org/class-Google_Service_YouTube_Video.html

class YouTubeVideo
{
    // video id
    public $id;

    // generate at https://console.developers.google.com/apis
    private $apiKey = 'REPLACE_ME';

    // google youtube service
    private $youtube;

    public function __construct($id)
    {
        $client = new Google_Client();
        $client->setDeveloperKey($this->apiKey);

        $this->youtube = new Google_Service_YouTube($client);

        $this->id = $id;
    }

    /*
     * @return Google_Service_YouTube_VideoStatistics
     * Google_Service_YouTube_VideoStatistics Object ( [commentCount] => 0 [dislikeCount] => 0 [favoriteCount] => 0 [likeCount] => 0 [viewCount] => 5 )  
     */
    public function getStatistics()
    {
        try{
            // Call the API's videos.list method to retrieve the video resource.
            $response = $this->youtube->videos->listVideos("statistics",
                array('id' => $this->id));

            $googleService = current($response->items);
            if($googleService instanceof Google_Service_YouTube_Video) {
                return $googleService->getStatistics();
            }
        } catch (Google_Service_Exception $e) {
            return sprintf('<p>A service error occurred: <code>%s</code></p>',
                htmlspecialchars($e->getMessage()));
        } catch (Google_Exception $e) {
            return sprintf('<p>An client error occurred: <code>%s</code></p>',
                htmlspecialchars($e->getMessage()));
        }
    }
}

Another similar solution:

>>> a=datetime.now()
>>> "%s:%s.%s" % (a.hour, a.minute, a.microsecond)
'14:28.971209'

Yes, I know I didn't get the string formatting perfect.

function setCookie(name,value,days) {
    var expires = "";

        expires = "; expires=" + date.toUTCString();
    }
    document.cookie = name + "=" + (value || "")  + expires + "; path=/";
}
function getCookie(name) {
    var nameEQ = name + "=";
    var ca = document.cookie.split(';');
    for(var i=0;i < ca.length;i++) {

        if (c.indexOf(nameEQ) == 0) return c.substring(nameEQ.length,c.length);
    }
    return null;
}
function eraseCookie(name) {   
    document.cookie = name+'=; Max-Age=-99999999;';

1. press Esc
2. type ":wq" (without quotes)
3. Press Enter

The simplest way:

if (Request.IsAuthenticated) ...

Use "\\" to escape the \ character.

I wrote a more easy-to-use implementation for @enrico.bacis's answer. It supports both Linux(python2.7 and python3.5) and Windows(python2.7). It may support Mac OS, but I didn't test it. If you tried it on Mac, please tell me the result.

Every RDBMS is a DBMS, but the opposite is not true: RDBMS is a DBMS which is based on the relational model, but not every DBMS must be relational.

However, since RDBMS are most common, sometimes the term DBMS is used to denote a DBMS which is NOT relational. It depends on the context.

In 12c you can make use of the fact that columns which are set from invisible to visible are displayed as the last column of the table: Tips and Tricks: Invisible Columns in Oracle Database 12c

Maybe that is the 'trick' @jeffrey-kemp was talking about in his comment, but the link there does not work anymore.

Example:

ALTER TABLE my_tab ADD (col_3 NUMBER(10));
ALTER TABLE my_tab MODIFY (
  col_1 invisible,
  col_2 invisible
);
ALTER TABLE my_tab MODIFY (
  col_1 visible,
  col_2 visible
);

Now col_3 would be displayed first in a SELECT * FROM my_tab statement.

Note: This does not change the physical order of the columns on disk, but in most cases that is not what you want to do anyway. If you really want to change the physical order, you can use the DBMS_REDEFINITION package.

I had this problem and it went away when I moved from ADO.Net to Dapper for my queries.

I'm running Windows 10 and had this problem after I changed my SSD, I fixed it by disabling the VT support on Bios. I got a different error after I ran the installer. I rebooted and enabled VT support again and voila, working now.

This was critical to get this to work with Entity Framework:

var genericCollection = list as ICollection<T>;

if (genericCollection != null)
{
   //your code 
}

You might have to escape the forward slashes though, depending on context.

C++03's categories are too restricted to capture the introduction of rvalue references correctly into expression attributes.

With the introduction of them, it was said that an unnamed rvalue reference evaluates to an rvalue, such that overload resolution would prefer rvalue reference bindings, which would make it select move constructors over copy constructors. But it was found that this causes problems all around, for example with Dynamic Types and with qualifications.

To show this, consider

int const&& f();

int main() {
  int &&i = f(); // disgusting!
}

On pre-xvalue drafts, this was allowed, because in C++03, rvalues of non-class types are never cv-qualified. But it is intended that const applies in the rvalue-reference case, because here we do refer to objects (= memory!), and dropping const from non-class rvalues is mainly for the reason that there is no object around.

The issue for dynamic types is of similar nature. In C++03, rvalues of class type have a known dynamic type - it's the static type of that expression. Because to have it another way, you need references or dereferences, which evaluate to an lvalue. That isn't true with unnamed rvalue references, yet they can show polymorphic behavior. So to solve it,

• unnamed rvalue references become xvalues. They can be qualified and potentially have their dynamic type different. They do, like intended, prefer rvalue references during overloading, and won't bind to non-const lvalue references.

• What previously was an rvalue (literals, objects created by casts to non-reference types) now becomes an prvalue. They have the same preference as xvalues during overloading.

• What previously was an lvalue stays an lvalue.

And two groupings are done to capture those that can be qualified and can have different dynamic types (glvalues) and those where overloading prefers rvalue reference binding (rvalues).

Try -

var newstring = @"a\\b".Replace(@"\\",@"\");

To resolve the error below on my Macbook Catalina 10.15.4:

I ran the command below and got round the problem above:

You probably had a typo when you first ran it.

evaluating 0.5 % 0.3 returns '0.2' (A double) as expected.

Mindprod has a good overview of how modulus works in Java.

Honestly, I was in the same boat as you. I've got a C++ Library that I wanted to connect to a graphing utility. I ended up using Boost Python and matplotlib. It was the best one that I could find.

As a side note: I was also wary of licensing. matplotlib and the boost libraries can be integrated into proprietary applications.

Here's an example of the code that I used:

#include <boost/python.hpp>
#include <pygtk/pygtk.h>
#include <gtkmm.h>

using namespace boost::python;
using namespace std;

// This is called in the idle loop.
bool update(object *axes, object *canvas) {
    static object random_integers = object(handle<>(PyImport_ImportModule("numpy.random"))).attr("random_integers");
    axes->attr("scatter")(random_integers(0,1000,1000), random_integers(0,1000,1000));
    axes->attr("set_xlim")(0,1000);
    axes->attr("set_ylim")(0,1000);
    canvas->attr("draw")();
    return true;
}

int main() {
    try {
        // Python startup code
        Py_Initialize();
        PyRun_SimpleString("import signal");
        PyRun_SimpleString("signal.signal(signal.SIGINT, signal.SIG_DFL)");

        // Normal Gtk startup code
        Gtk::Main kit(0,0);

        // Get the python Figure and FigureCanvas types.
        object Figure = object(handle<>(PyImport_ImportModule("matplotlib.figure"))).attr("Figure");
        object FigureCanvas = object(handle<>(PyImport_ImportModule("matplotlib.backends.backend_gtkagg"))).attr("FigureCanvasGTKAgg");

        // Instantiate a canvas
        object figure = Figure();
        object canvas = FigureCanvas(figure);
        object axes = figure.attr("add_subplot")(111);
        axes.attr("hold")(false);

        // Create our window.
        Gtk::Window window;
        window.set_title("Engineering Sample");
        window.set_default_size(1000, 600);

        // Grab the Gtk::DrawingArea from the canvas.
        Gtk::DrawingArea *plot = Glib::wrap(GTK_DRAWING_AREA(pygobject_get(canvas.ptr())));

        // Add the plot to the window.
        window.add(*plot);
        window.show_all();

        // On the idle loop, we'll call update(axes, canvas).
        Glib::signal_idle().connect(sigc::bind(&update, &axes, &canvas));

        // And start the Gtk event loop.
        Gtk::Main::run(window);

    } catch( error_already_set ) {
        PyErr_Print();
    }

For clear frame, first need to destroy all widgets inside the frame,. it will clear frame.

import tkinter as tk
from tkinter import *
root = tk.Tk()

frame = Frame(root)
frame.pack(side="top", expand=True, fill="both")

lab = Label(frame, text="hiiii")
lab.grid(row=0, column=0, padx=10, pady=5)

def clearFrame():
    # destroy all widgets from frame
    for widget in frame.winfo_children():
       widget.destroy()
    
    # this will clear frame and frame will be empty
    # if you want to hide the empty panel then
    frame.pack_forget()

frame.but = Button(frame, text="clear frame", command=clearFrame)
frame.but.grid(row=0, column=1, padx=10, pady=5)

# then whenever you add data in frame then you can show that frame
lab2 = Label(frame, text="hiiii")
lab2.grid(row=1, column=0, padx=10, pady=5)
frame.pack()
root.mainloop()

I had the same problem. I even re-installed VS 2008 but the problem did not go away. However, when I deleted all the break points then it started to work.

Debug->Delete All Breakpoints

I think it was happening because I had deleted an aspx page that had break points in its code, and then I created another page with the same name. This probably confused the VS 2008.

You can do this with position:absolute; on the #second div like this :

FIDDLE

CSS :

#wrapper{
    position:relative;
}

#second {
    position:absolute;
    top:200px;
    bottom:0;
    left:0;
    width:300px;
    background-color:#9ACD32;
}

EDIT : Alternative solution

Depending on your layout and the content you have in those divs, you could make it much more simple and with less markup like this :

FIDDLE

HTML :

<div id="wrapper">
    <div id="first"></div>
</div>

CSS :

#wrapper {
    height:100%;
    width:300px;
    background-color:#9ACD32;
}
#first {
    background-color:#F5DEB3;
    height: 200px;
}

A web service endpoint is the URL that another program would use to communicate with your program. To see the WSDL you add ?wsdl to the web service endpoint URL.

Web services are for program-to-program interaction, while web pages are for program-to-human interaction.

So: Endpoint is: http://www.blah.com/myproject/webservice/webmethod

Therefore, WSDL is: http://www.blah.com/myproject/webservice/webmethod?wsdl

To expand further on the elements of a WSDL, I always find it helpful to compare them to code:

A WSDL has 2 portions (physical & abstract).

Physical Portion:

Definitions - variables - ex: myVar, x, y, etc.

Types - data types - ex: int, double, String, myObjectType

Operations - methods/functions - ex: myMethod(), myFunction(), etc.

Messages - method/function input parameters & return types

• ex: public myObjectType myMethod(String myVar)

Porttypes - classes (i.e. they are a container for operations) - ex: MyClass{}, etc.

Abstract Portion:

Binding - these connect to the porttypes and define the chosen protocol for communicating with this web service. - a protocol is a form of communication (so text/SMS, vs. phone vs. email, etc.).

Service - this lists the address where another program can find your web service (i.e. your endpoint).

Right click in Project / Clean

That always works for me

Add grid with defined height and width for columns and rows. Then add ScrollViewer and inside it add the dataGrid.

To rotate by 45 degrees in IE, you need the following code in your stylesheet:

filter: progid:DXImageTransform.Microsoft.Matrix(sizingMethod='auto expand', M11=0.7071067811865476, M12=-0.7071067811865475, M21=0.7071067811865475, M22=0.7071067811865476); /* IE6,IE7 */
-ms-filter: "progid:DXImageTransform.Microsoft.Matrix(SizingMethod='auto expand', M11=0.7071067811865476, M12=-0.7071067811865475, M21=0.7071067811865475, M22=0.7071067811865476)"; /* IE8 */

You’ll note from the above that IE8 has different syntax to IE6/7. You need to supply both lines of code if you want to support all versions of IE.

The horrible numbers there are in Radians; you’ll need to work out the figures for yourself if you want to use an angle other than 45 degrees (there are tutorials on the internet if you look for them).

Also note that the IE6/7 syntax causes problems for other browsers due to the unescaped colon symbol in the filter string, meaning that it is invalid CSS. In my tests, this causes Firefox to ignore all CSS code after the filter. This is something you need to be aware of as it can cause hours of confusion if you get caught out by it. I solved this by having the IE-specific stuff in a separate stylesheet which other browsers didn’t load.

All other current browsers (including IE9 and IE10 — yay!) support the CSS3 transform style (albeit often with vendor prefixes), so you can use the following code to achieve the same effect in all other browsers:

-moz-transform: rotate(45deg);  /* FF3.5/3.6 */
-o-transform: rotate(45deg);  /* Opera 10.5 */
-webkit-transform: rotate(45deg);  /* Saf3.1+ */
transform: rotate(45deg);  /* Newer browsers (incl IE9) */

Hope that helps.

Edit

Since this answer is still getting up-votes, I feel I should update it with information about a JavaScript library called CSS Sandpaper that allows you to use (near) standard CSS code for rotations even in older IE versions.

Once you’ve added CSS Sandpaper to your site, you should then be able to write the following CSS code for IE6–8:

-sand-transform: rotate(40deg);

Much easier than the traditional filter style you'd normally need to use in IE.

Edit

Also note an additional quirk specifically with IE9 (and only IE9), which supports both the standard transform and the old style IE -ms-filter. If you have both of them specified, this can result in IE9 getting completely confused and rendering just a solid black box where the element would have been. The best solution to this is to avoid the filter style by using the Sandpaper polyfill mentioned above.

Well, at the risk of making things too easy...

for (var member in myObject) delete myObject[member];

...would seem to be pretty effective in cleaning the object in one line of code with a minimum of scary brackets. All members will be truly deleted instead of left as garbage.

Obviously if you want to delete the object itself, you'll still have to do a separate delete() for that.

The easiest way to do it, at least for me, is:

Conditional format-> Add new rule->Set your own formula:

=ISNA(MATCH(A2;$B:$B;0))

Where A2 is the first element in column A to be compared and B is the column where A's element will be searched.

Once you have set the formula and picked the format, apply this rule to all elements in the column.

Hope this helps

On top of your lastest jsfiddle, you just missed one thing:

#sidebar_wrap {
  width:40%;
  height:200px;
  background:green;
  float:right;
}
#sidebar {
  width:inherit;
  margin-top:10px;
  background-color:limegreen;
  position:fixed;
  max-width: 240px; /*This is you missed*/
}

But, how this will solve your problem? Simple, lets explain why is bigger than expect first.

Fixed element #sidebar will use window width size as base to get its own size, like every other fixed element, once in this element is defined width:inherit and #sidebar_wrap has 40% as value in width, then will calculate window.width * 40%, then when if your window width is bigger than your .container width, #sidebar will be bigger than #sidebar_wrap.

This is way, you must set a max-width in your #sidebar_wrap, to prevent to be bigger than #sidebar_wrap.

Check this jsfiddle that shows a working code and explain better how this works.

I like to separate my filters from other portions of the code and test those as I outline on my blog here http://coding.grax.com/2013/08/testing-custom-linq-filter-operators.html

That being said, the filter logic being tested is not identical to the filter logic executed when the program is run due to the translation between the LINQ expression and the underlying query language, such as T-SQL. Still, this allows me to validate the logic of the filter. I don't worry too much about the translations that happen and things such as case-sensitivity and null-handling until I test the integration between the layers.

In later versions of Angular2 there is no need of manually setting Content-Type header and encoding the body if you pass an object of the right type as body.

You simply can do this

import { URLSearchParams } from "@angular/http"


testRequest() {
  let data = new URLSearchParams();
  data.append('username', username);
  data.append('password', password);

  this.http
    .post('/api', data)
      .subscribe(data => {
            alert('ok');
      }, error => {
          console.log(error.json());
      });
}

This way angular will encode the body for you and will set the correct Content-Type header.

P.S. Do not forget to import URLSearchParams from @angular/http or it will not work.

1 - Treat functions as objects.

2 - The apply method is similar to __call __ in Python, which allows you to use an instance of a given class as a function.

It's best practice only to escape the quotes when you need to - if you can get away without escaping it, then do!

The only times you should need to escape are when trying to put " inside a string, or ' in a character:

String quotes = "He said \"Hello, World!\"";
char quote = '\'';

A Python 2+3 compatible solution is:

import sys

if sys.version_info[0] >= 3:
    from urllib.request import urlretrieve
else:
    # Not Python 3 - today, it is most likely to be Python 2
    # But note that this might need an update when Python 4
    # might be around one day
    from urllib import urlretrieve

# Get file from URL like this:
urlretrieve("http://www-scf.usc.edu/~chiso/oldspice/m-b1-hello.mp3")

Here's an example of how to deep copy a 2D list:

  b = [x[:] for x in a]

The ID of the two repos are both localSnap; that's probably not what you want and it might confuse Maven.

If that's not it: There might be more repository elements in your POM. Search the output of mvn help:effective-pom for repository to make sure the number and place of them is what you expect.

From the documentation:

/is Includes the same files. /it Includes "tweaked" files.

"Same files" means files that are identical (name, size, times, attributes). "Tweaked files" means files that have the same name, size, and times, but different attributes.

robocopy src dst sample.txt /is      # copy if attributes are equal
robocopy src dst sample.txt /it      # copy if attributes differ
robocopy src dst sample.txt /is /it  # copy irrespective of attributes

This answer on Super User has a good explanation of what kind of files the selection parameters match.

With that said, I could reproduce the behavior you describe, but from my understanding of the documentation and the output robocopy generated in my tests I would consider this a bug.

The file is listed as copied, and since it becomes a same file after the first robocopy run at least the times are synced. However, even though seven bytes have been copied according to the output no data was actually written to the destination file in both cases despite the data flag being set (via /copyall). The behavior also doesn't change if the data flag is set explicitly (/copy:d).

I had to modify the last write time to get robocopy to actually synchronize the data.

An admittedly ugly workaround would be to change the last write time of same/tweaked files to force robocopy to copy the data:

& robocopy src dst /is /it /l /ndl /njh /njs /ns /nc |
  Where-Object { $_.Trim() } |
  ForEach-Object {
    $f = Get-Item $_
    $f.LastWriteTime = $f.LastWriteTime.AddSeconds(1)
  }
& robocopy src dst /copyall /mir

Switching to xcopy is probably your best option:

& xcopy src dst /k/r/e/i/s/c/h/f/o/x/y

Generate the object files with gcc, then use ar to bundle them into a static library.

char ch = 't';
char chArray[2];
sprintf(chArray, "%c", ch);
char chOutput[10]="tes";
strcat(chOutput, chArray);
cout<<chOutput;

OUTPUT:

test

Executing seq(1, 10, 1) does what 1:10 does. You can change the last parameter of seq, i.e. by, to be the step of whatever size you like.

> #a vector of even numbers
> seq(0, 10, by=2) # Explicitly specifying "by" only to increase readability 
> [1]  0  2  4  6  8 10

looks like you have maven project and so resources are in classpath by

go for

getClass().getResource("classpath:storedProcedures.sql")

I came here with the same Error, though one with a different origin.

It is caused by unsupported float index in 1.12.0 and newer numpy versions even if the code should be considered as valid.

An int type is expected, not a np.float64

Solution: Try to install numpy 1.11.0

sudo pip install -U numpy==1.11.0.

I got the same error but I solved by using regsvr32.exe in C:\Windows\SysWOW64. Because we use x64 system. So if your machine is also x64, the ocx/dll must registered also with regsvr32 x64 version

There are plenty of templating systems that offer more compact syntax for your views. Smarty is venerable and popular. This article lists 10 others.

I just want to add to the already accepted answer. I was stuck on this, but I was going a different route on handling the complete event. Rather than running await, I add a completed handler to the task.

Comments.AsAsyncAction().Completed += new AsyncActionCompletedHandler(CommentLoadComplete);

Where the event handler looks like this

private void CommentLoadComplete(IAsyncAction sender, AsyncStatus status )
{
    if (status == AsyncStatus.Canceled)
    {
        return;
    }
    CommentsItemsControl.ItemsSource = Comments.Result;
    CommentScrollViewer.ScrollToVerticalOffset(0);
    CommentScrollViewer.Visibility = Visibility.Visible;
    CommentProgressRing.Visibility = Visibility.Collapsed;
}

With this route, all the handling is already done for you, when the task is cancelled it just triggers the event handler and you can see if it was cancelled there.

You can define one border per side only. You would have to add an extra element for that!

System.Net.WebUtility class is available starting from .NET 4.0 (You don't need System.Web.dll dependency).

Try this may work..

<html>
   <?php $num = 1; ?>
   <div id="Count"><?php echo $num; ?></div>
   <input type = "button" name = "lol" value = "Click to increment" onclick = "Inc()">
   <br>
   <script>
   function Inc() {
       i = parseInt(document.getElementById('Count').innerHTML);
       document.getElementById('Count').innerHTML = i+1;
   }
   </script>
</html>
