For Ionic 3 devs. I had to update the platforms/android/project.properties file ONLY on:

cordova.system.library.2

to be v4:28.0.0+ otherwise the build kept failing.

After doing so, my project.properties file contents are shown below:

I hope this helps someone. Was a real problem for me.

The easiest way use it as array is use vector::data() member.

@Multipart
@POST(Config.UPLOAD_IMAGE)
Observable<Response<String>> uploadPhoto(@Header("Access-Token") String header, @Part MultipartBody.Part imageFile);

And you can call this api like this:

   public void uploadImage(File file) {
     // create multipart
     RequestBody requestFile = RequestBody.create(MediaType.parse("multipart/form-data"), file);
    MultipartBody.Part body = MultipartBody.Part.createFormData("image", file.getName(), requestFile);

    // upload
    getViewInteractor().showProfileUploadingProgress();

    Observable<Response<String>> observable = api.uploadPhoto("",body);

    // on Response
    subscribeForNetwork(observable, new ApiObserver<Response<String>>() {
        @Override
        public void onError(Throwable e) {
            getViewInteractor().hideProfileUploadingProgress();
        }

        @Override
        public void onResponse(Response<String> response) {

            if (response.code() != 200) {
                Timber.d("error " + response.code());
                return;
            }
            getViewInteractor().hideProfileUploadingProgress();
            getViewInteractor().onProfileImageUploadSuccess(response.body());

        }
    });

}

The separation between content and layout makes it also easier to generate printer-friendly layouts or just different skins (styles) for your site, without having to create different html-files. Some browser (like Firefox) even support selecting a stylesheet from the view-menu.

And I do think it's easier to maintain a tableless layout. You don't have to worry about rowspans, colspans, etc. You just create some container-divs and place the content where you need to. And that said I think it also more readable (<div id="sidebar"> vs <tr><td>...</td><td>...<td>sidebar</td></tr>).

It's just a little 'trick' you have to learn (and once you mastered the trick, I think it's easier and makes more sense).

You can use the below code in the onclick listener of edittext

  TimePickerDialog timePickerDialog = new TimePickerDialog(MainActivity.this,
    new TimePickerDialog.OnTimeSetListener() {

        @Override
        public void onTimeSet(TimePicker view, int hourOfDay,
                              int minute) {

            tv_time.setText(hourOfDay + ":" + minute);
        }
    }, hour, minute, false);
     timePickerDialog.show();

You can see the full code at Android timepicker example

It can be useful if mixed new property add in runtime:

data = { ...data, newPropery: value}

However, spread operator use shallow copy but here we assign data to itself so should lose nothing

You're looking for the onclose event.

see: https://developer.mozilla.org/en/DOM/window.onclose

note that not all browsers support this (for example firefox 2)

In case you are adding build with deployment target >9, add these keys to info.plist in case you are using camera and photos: Privacy - Camera Usage Description and Privacy - Photo Library Usage Description with a valid description.

I had the same issue when I submitted with blank string for these keys.

"N/A" is not a string it is an error, try this:

=if(ISNA(A1),C1)

you have to place this fomula in cell B1 so it will get the value of your formula

You just need to divide each element by the sum of the values in its column.

Doing this should suffice:

data.perc <- apply(data, 2, function(x){x/sum(x)})

Note that the second parameter tells apply to apply the provided function to columns (using 1 you would apply it to rows). The anonymous function, then, gets passed each data column, one at a time.

>>> "{:.1f}".format(45.34531)
'45.3'

Or use the builtin round:

>>> round(45.34531, 1)
45.299999999999997

As another answer already said, call select myfunc(:y) from dual; , but you might find declaring and setting a variable in sqlplus a little tricky:

sql> var y number

sql> begin
  2  select 7 into :y from dual;
  3  end;
  4  /

PL/SQL procedure successfully completed.

sql> print :y

         Y
----------
         7

sql> select myfunc(:y) from dual;

If you want the first line and then you want to perform some operation on file this code will helpful.

with open(filename , 'r') as f:
    first_line = f.readline()
    for line in f:
            # Perform some operations

As others have pointed out, ideally, the foreign key would be created as a reference to a primary key (usually an IDENTITY column). However, we don't live in an ideal world, and sometimes even a "small" change to a schema can have significant ripple effects to the application logic.

Consider the case of a Customer table with a SSN column (and a dumb primary key), and a Claim table that also contains a SSN column (populated by business logic from the Customer data, but no FK exists). The design is flawed, but has been in use for several years, and three different applications have been built on the schema. It should be obvious that ripping out Claim.SSN and putting in a real PK-FK relationship would be ideal, but would also be a significant overhaul. On the other hand, putting a UNIQUE constraint on Customer.SSN, and adding a FK on Claim.SSN, could provide referential integrity, with little or no impact on the applications.

Don't get me wrong, I'm all for normalization, but sometimes pragmatism wins over idealism. If a mediocre design can be helped with a band-aid, surgery might be avoided.

All of these answers were a little hacky compared to what I would expect from a framework, the simplest method, I think by far, if you are using the rest framework:

rep = YourSerializerClass().to_representation(your_instance)
json.dumps(rep)

This uses the Serializer directly, respecting the fields you've defined on it, as well as any associations, etc.

Issue is that it is failed to decrypt 256 bits of encryption.

My solution was subtle and I didn't see it listed already.

I was using reactive forms in an Angular Materials Dialog component that wasn't declared in app.module.ts. The main component was declared in app.module.ts and would open the dialog component but the dialog component was not explicitly declared in app.module.ts.

I didn't have any problems using the dialog component normally except that the form threw this error whenever I opened the dialog.

Can't bind to 'formGroup' since it isn't a known property of 'form'.

Archive libraries (.a) are statically linked i.e when you compile your program with -c option in gcc. So, if there's any change in library, you need to compile and build your code again.

The advantage of .so (shared object) over .a library is that they are linked during the runtime i.e. after creation of your .o file -o option in gcc. So, if there's any change in .so file, you don't need to recompile your main program. But make sure that your main program is linked to the new .so file with ln command.

This will help you to build the .so files. http://www.yolinux.com/TUTORIALS/LibraryArchives-StaticAndDynamic.html

Hope this helps.

If you are working a lot with graphs and ggplot, you might be tired to add the theme() each time. If you don't want to change the default theme as suggested earlier, you may find easier to create your own personal theme.

personal_theme = theme(plot.title = 
element_text(hjust = 0.5))

Say you have multiple graphs, p1, p2 and p3, just add personal_theme to them.

p1 + personal_theme
p2 + personal_theme
p3 + personal_theme

dat <- data.frame(
  time = factor(c("Lunch","Dinner"), 
levels=c("Lunch","Dinner")),
  total_bill = c(14.89, 17.23)
)
p1 = ggplot(data=dat, aes(x=time, y=total_bill, 
fill=time)) + 
  geom_bar(colour="black", fill="#DD8888", 
width=.8, stat="identity") + 
  guides(fill=FALSE) +
  xlab("Time of day") + ylab("Total bill") +
  ggtitle("Average bill for 2 people")

p1 + personal_theme

In irb:

>>d = DateTime.now
=> #<DateTime: 11783702280454271/4800000000,5/12,2299161>
>> "#{d.hour.to_i - d.zone.to_i}:#{d.min}:#{d.sec}"
=> "11:16:41"

will convert the time to the utc. But as posted if it is just Time you can use:

Time.now.utc

and get it straight away.

np.array(M).ravel()

If you care for speed; But if you care for memory:

np.asarray(M).ravel()

Just to expand on and improve some of the above answers:

First, I'll check the mkdir man page for GNU Coreutils 8.26 -- it gives us this information about the option '-m' and '-p' (can also be given as --mode=MODE and --parents, respectively):

...set[s] file mode (as in chmod), not a=rwx - umask

...no error if existing, make parent directories as needed

The statements are vague and unclear in my opinion. But basically, it says that you can make the directory with permissions specified by "chmod numeric notation" (octals) or you can go "the other way" and use a/your umask.

Side note: I say "the other way" since the umask value is actually exactly what it sounds like -- a mask, hiding/removing permissions rather than "granting" them as with chmod's numeric octal notation.

You can execute the shell-builtin command umask to see what your 3-digit umask is; for me, it's 022. This means that when I execute mkdir yodirectory in a given folder (say, mahome) and stat it, I'll get some output resembling this:

               755                   richard:richard         /mahome/yodirectory
 #          permissions                 user:group      what I just made (yodirectory),
 # (owner,group,others--in that order)                 where I made it (i.e. in mahome)
 # 

Now, to add just a tiny bit more about those octal permissions. When you make a directory, "your system" take your default directory perms' [which applies for new directories (its value should 777)] and slaps on yo(u)mask, effectively hiding some of those perms'. My umask is 022--now if we "subtract" 022 from 777 (technically subtracting is an oversimplification and not always correct - we are actually turning off perms or masking them)...we get 755 as stated (or "statted") earlier.

We can omit the '0' in front of the 3-digit octal (so they don't have to be 4 digits) since in our case we didn't want (or rather didn't mention) any sticky bits, setuids or setgids (you might want to look into those, btw, they might be useful since you are going 777). So in other words, 0777 implies (or is equivalent to) 777 (but 777 isn't necessarily equivalent to 0777--since 777 only specifies the permissions, not the setuids, setgids, etc.)

Now, to apply this to your question in a broader sense--you have (already) got a few options. All the answers above work (at least according to my coreutils). But you may (or are pretty likely to) run into problems with the above solutions when you want to create subdirectories (nested directories) with 777 permissions all at once. Specifically, if I do the following in mahome with a umask of 022:

mkdir -m 777 -p yodirectory/yostuff/mastuffinyostuff
# OR (you can swap 777 for 0777 if you so desire, outcome will be the same)
install -d -m 777 -p yodirectory/yostuff/mastuffinyostuff

I will get perms 755 for both yodirectory and yostuff, with only 777 perms for mastuffinyostuff. So it appears that the umask is all that's slapped on yodirectory and yostuff...to get around this we can use a subshell:

( umask 000 && mkdir -p yodirectory/yostuff/mastuffinyostuff )

and that's it. 777 perms for yostuff, mastuffinyostuff, and yodirectory.

I had the same problem with Firefox 30 + Selenium 2.49 + Ubuntu 15.04.

It worked fine with Ubuntu 14 but after upgrade to 15.04 I got same RANDR warning and problem at starting Firefox using Xfvb.

After adding +extension RANDR it worked again.

The closest thing is likely Dav Glass's experimental work using node.js, express and YUI3. Basically, he explains how YUI3 is used to render markup on the server side, then sent to the client where binding to event and data occurs. The beauty is YUI3 is used as-is on both the client and the server. Makes a lot of sense. The one big issue is there is not yet a production ready server-side DOM library.

For any of you calling back to the same server for your IFRAME, pass this simple header inside the IFRAME page:

Content-Security-Policy: frame-ancestors 'self'

Or, add this to your web server's CSP configuration.

I had your code setup on jsFiddle to try diagnose the problem.

char * strdup(const char * s)
{
  size_t len = 1+strlen(s);
  char *p = malloc(len);

  return p ? memcpy(p, s, len) : NULL;
}

Maybe the code is a bit faster than with strcpy() as the \0 char doesn't need to be searched again (It already was with strlen()).

i think you have only defined the function. you are not triggering it anywhere.

please do

window.onload = addList();

or trigger it on some other event

after its definition

A regular REST API uses HTTP as the underlying protocol for communication, which follows the request and response paradigm, meaning the communication involves the client requesting some data or resource from a server, and the server responding back to that client. However, HTTP is a stateless protocol, so every request-response cycle will end up having to repeat the header and metadata information. This incurs additional latency in case of frequently repeated request-response cycles.

With WebSockets, although the communication still starts off as an initial HTTP handshake, it is further upgraded to follow the WebSockets protocol (i.e. if both the server and the client are compliant with the protocol as not all entities support the WebSockets protocol).

Now with WebSockets, it is possible to establish a full-duplex and persistent connection between the client and a server. This means that unlike a request and a response, the connection stays open for as long as the application is running (i.e. it’s persistent), and since it is full-duplex, two-way simultaneous communication is possible i.e now the server is capable of initiating communication and 'push' some data to the client when new data (that the client is interested in) becomes available.

The WebSockets protocol is stateful and allows you to implement the Publish-Subscribe (or Pub/Sub) messaging pattern which is the primary concept used in the real-time technologies where you are able to get new updates in the form of server push without the client having to request (refresh the page) repeatedly. Examples of such applications are Uber car's location tracking, Push Notifications, Stock market prices updating in real-time, chat, multiplayer games, live online collaboration tools, etc.

You can check out a deep dive article on Websockets which explains the history of this protocol, how it came into being, what it’s used for and how you can implement it yourself.

Here's a video from a presentation I did about WebSockets and how they are different from using the regular REST APIs: Standardisation and leveraging the exponential rise in data streaming

First of all, the stack pointer points to the bottom of the stack since x86 stacks build from high address values to lower address values. The stack pointer is the point where the next call to push (or call) will place the next value. It's operation is equivalent to the C/C++ statement:

 // push eax
 --*esp = eax
 // pop eax
 eax = *esp++;

 // a function call, in this case, the caller must clean up the function parameters
 move eax,some value
 push eax
 call some address  // this pushes the next value of the instruction pointer onto the
                    // stack and changes the instruction pointer to "some address"
 add esp,4 // remove eax from the stack

 // a function
 push ebp // save the old stack frame
 move ebp, esp
 ... // do stuff
 pop ebp  // restore the old stack frame
 ret

The base pointer is top of the current frame. ebp generally points to your return address. ebp+4 points to the first parameter of your function (or the this value of a class method). ebp-4 points to the first local variable of your function, usually the old value of ebp so you can restore the prior frame pointer.

When hashing, don't use fast hash algorithms such as MD5 (many hardware implementations exist). Use something like SHA-512. For passwords, slower hashes are better.

The faster you can create hashes, the faster any brute force checker can work. Slower hashes will therefore slow down brute forcing. A slow hash algorithm will make brute forcing impractical for longer passwords (8 digits +)

As you described, you will need to use a different method based on different versions of iOS. If your team is using both Xcode 5 (which doesn't know about any iOS 8 selectors) and Xcode 6, then you will need to use conditional compiling as follows:

#if __IPHONE_OS_VERSION_MAX_ALLOWED >= 80000
if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    // use registerUserNotificationSettings
} else {
    // use registerForRemoteNotificationTypes:
}
#else
// use registerForRemoteNotificationTypes:
#endif

If you are only using Xcode 6, you can stick with just this:

if ([application respondsToSelector:@selector(registerUserNotificationSettings:)]) {
    // use registerUserNotificationSettings
} else {
    // use registerForRemoteNotificationTypes:
}

The reason is here is that the way you get notification permissions has changed in iOS 8. A UserNotification is a message shown to the user, whether from remote or from local. You need to get permission to show one. This is described in the WWDC 2014 video "What's New in iOS Notifications"

Here's a query to update a table based on a comparison of another table. If record is not found in tableB, it will update the "active" value to "n". If it's found, will set the value to NULL

UPDATE tableA
LEFT JOIN tableB ON tableA.id = tableB.id
SET active = IF(tableB.id IS NULL, 'n', NULL)";

Hope this helps someone else.

The common name in the certicate for api.evercam.io is for *.herokuapp.com and there are no alternative subject names in the certificate. This means, that the certificate for api.evercam.io does not match the hostname and therefore the certificate verification fails. Same as true for www.evercam.io, e.g. try https://www.evercam.io with a browser and you get the error message, that the name in the certificate does not match the hostname.

So it is a problem which needs to be fixed by evercam.io. If you don't care about security, man-in-the-middle attacks etc you might disable verification of the certificate (curl --insecure), but then you should ask yourself why you use https instead of http at all.

    exit();
}

$query  = "SELECT CURRENT_USER();";
$query .= "SELECT Name FROM City ORDER BY ID LIMIT 20, 5";

/* execute multi query */
if ($mysqli->multi_query($query)) {
    do {
        /* store first result set */
        if ($result = $mysqli->store_result()) {
            while ($row = $result->fetch_row()) {
                printf("%s\n", $row[0]);
            }
            $result->free();
        }
        /* print divider */
        if ($mysqli->more_results()) {
            printf("-----------------\n");
        }
    } while ($mysqli->next_result());
}

/* close connection */
$mysqli->close();
?>

        ->setBorderStyle(PHPExcel_Style_Border::BORDER_THIN);

or

  $styleArray = array(
      'borders' => array(
          'allborders' => array(
              'style' => PHPExcel_Style_Border::BORDER_THIN
          )
      )
  );
$objPHPExcel->getDefaultStyle()->applyFromArray($styleArray);

And this can be used for all style properties, not just borders.

But column autosizing is structural rather than stylistic, and has to be set for each column on each worksheet individually.

EDIT

Note that default workbook style only applies to Excel5 Writer

You must place the label after a caption in order to for label to store the table's number, not the chapter's number.

Rab's answer works great, but not for Microsoft Edge, so I added a small adaptation for Edge as well:

https://jsfiddle.net/et9borp4/

function insertAtCursor(myField, myValue) {
    //IE support
    if (document.selection) {
        myField.focus();
        sel = document.selection.createRange();
        sel.text = myValue;
    }
    // Microsoft Edge
    else if(window.navigator.userAgent.indexOf("Edge") > -1) {
      var startPos = myField.selectionStart; 
      var endPos = myField.selectionEnd; 

      myField.value = myField.value.substring(0, startPos)+ myValue 
             + myField.value.substring(endPos, myField.value.length); 

      var pos = startPos + myValue.length;
      myField.focus();
      myField.setSelectionRange(pos, pos);
    }
    //MOZILLA and others
    else if (myField.selectionStart || myField.selectionStart == '0') {
        var startPos = myField.selectionStart;
        var endPos = myField.selectionEnd;
        myField.value = myField.value.substring(0, startPos)
            + myValue
            + myField.value.substring(endPos, myField.value.length);
    } else {
        myField.value += myValue;
    }
}

When using IN with a collection-valued parameter you don't need (...):

@NamedQuery(name = "EventLog.viewDatesInclude", 
    query = "SELECT el FROM EventLog el WHERE el.timeMark >= :dateFrom AND " 
    + "el.timeMark <= :dateTo AND " 
    + "el.name IN :inclList") 

firstarray and secondarray are converted to a pointer to int, when passed to printarray().

printarray(int arg[], ...) is equivalent to printarray(int *arg, ...)

However, this is not specific to C++. C has the same rules for passing array names to a function.

The SQLite3 PDO driver is named SQLite, not SQLite3, so you can do:

new SQLite("database");

For a SQLite2 database:

new SQLite2("database");

It's an automatically backed property, basically equivalent to:

private string type;
public string Type
{
   get{ return type; }
   set{ type = value; }
}

From the documentation (help copy-item -full):

    Accept pipeline input?       false
    Accept wildcard characters?  false

The simplest thing to do is:

Collections.sort(list, String.CASE_INSENSITIVE_ORDER);

Adding a separate answer because it is radically different.

You could use rgba and set the alpha channel low (to get transparency) to make your drop shadow less noticeable.

Try something like this (play with the .5)

-webkit-box-shadow: 0px -4px 7px rbga(230, 230, 230, .5);
-moz-box-shadow: 0px -4px 7px rbga(230, 230, 230, .5);
box-shadow: 0px -4px 7px rbga(230, 230, 230, .5);

Hope this helps!

Maybe, something like

Don't use absolute paths, make them relative to the 'resources' directory in your project. Quick and dirty code that displays the contents of MyTest.txt from the directory 'resources'.

        try {
            val = result.read(b);
            if (val > 0) {
                txt += new String(b, 0, val);
            }
        } catch (IOException e) {
            e.printStackTrace();
        } 
    } while (val > -1);
    System.out.println(txt);

I removed bin from the CLASSPATH. I found out that I was executing the java command from the directory where the HelloWorld.java is located, i.e.:

C:\Users\xyz\Documents\Java\javastudy\src\org\tij\exercises>java HelloWorld

So I moved back to the main directory and executed:

java org.tij.exercises.HelloWorld

and it worked, i.e.:

C:\Users\xyz\Documents\Java\javastudy\src>java org.tij.exercises.HelloWorld

Hello World!!

You need to use a concrete class and not an Abstract class while deserializing. if the Abstract class has several implementations then, in that case, you can use it as below-

  @JsonTypeInfo( use = JsonTypeInfo.Id.NAME, include = JsonTypeInfo.As.PROPERTY, property = "type")
    @JsonSubTypes({ 
      @Type(value = Bike.class, name = "bike"), 
      @Type(value = Auto.class, name = "auto"), 
      @Type(value = Car.class, name = "car")
    })
    public abstract class Vehicle {
        // fields, constructors, getters, setters
    }

You could use table, i.e.

n_occur <- data.frame(table(vocabulary$id))

gives you a data frame with a list of ids and the number of times they occurred.

n_occur[n_occur$Freq > 1,]

tells you which ids occurred more than once.

vocabulary[vocabulary$id %in% n_occur$Var1[n_occur$Freq > 1],]

returns the records with more than one occurrence.

Without using dynamic SQL, you have to take the input variable and use a split function to put the data into a temp table and then join to that.

A stateful app is one that stores information about what has happened or changed since it started running. Any public info about what "mode" it is in, or how many records is has processed, or whatever, makes it stateful.

Stateless apps don't expose any of that information. They give the same response to the same request, function or method call, every time. HTTP is stateless in its raw form - if you do a GET to a particular URL, you get (theoretically) the same response every time. The exception of course is when we start adding statefulness on top, e.g. with ASP.NET web apps :) But if you think of a static website with only HTML files and images, you'll know what I mean.

Parts of the GCC runtime (the exception handling, in particular) are dependent on the threading model being used. So, if you're using the version of the runtime that was built with POSIX threads, but decide to create threads in your own code with the Win32 APIs, you're likely to have problems at some point.

Even if you're using the Win32 threading version of the runtime you probably shouldn't be calling the Win32 APIs directly. Quoting from the MinGW FAQ:

As MinGW uses the standard Microsoft C runtime library which comes with Windows, you should be careful and use the correct function to generate a new thread. In particular, the CreateThread function will not setup the stack correctly for the C runtime library. You should use _beginthreadex instead, which is (almost) completely compatible with CreateThread.

I have very simple way to do this. It worked out perfect for me.

Dictionary<string, string> types = new Dictionary<string, string>();

types.Add("1", "one");
types.Add("2", "two");
types.Add("3", "three");

Console.WriteLine("Please type a key to show its value: ");
string rLine = Console.ReadLine();

if(types.ContainsKey(rLine))
{
    string value_For_Key = types[rLine];
    Console.WriteLine("Value for " + rLine + " is" + value_For_Key);
}

This is inspired by the Haskell implementation using list comprehension:

def permutation(list):
    if len(list) == 0:
        return [[]]
    else:
        return [[x] + ys for x in list for ys in permutation(delete(list, x))]

def delete(list, item):
    lc = list[:]
    lc.remove(item)
    return lc

FOR CHORME:

I´ve tried all suggestions here. But diden't work. My college found a great solution, that works better:

You should NOT scale past 1.0

And include translateZ(0) in the hover but NOT in the none-hover/initial position.

Example:

a {
    transition: all 500ms cubic-bezier(0.165, 0.840, 0.440, 1.000);
    transform: scale(0.8, 0.8);
}

a:hover {
    transform: translateZ(0)scale(1.0, 1.0);
}

I just had this problem

1. Having multiple user using the same repo caused the problem
2. Logout evey other user using the repo

Hope this helps

Yup! That's very straight forward and that's where the package strategy comes into play. there are three ways to my knowledge. folder structure:

GOPATH/src/ github.com/ abc/ myproject/ adapter/ main.go pkg1 pkg2 warning: adapter can contain package main only and sun directories

1. navigate to "adapter" folder. Run:

    go build main.go

2. navigate to "adapter" folder. Run:

    go build main.go

3. navigate to GOPATH/src recognize relative path to package main, here "myproject/adapter". Run:

    go build myproject/adapter

exe file will be created at the directory you are currently at.

Here are clarified instruction combining Dawn Song's answer and Marmor's answer.

Drag a long Press Gesture Recognizer and drop it into your Table Cell. It will jump to the bottom of the list on the left.

Then connect the gesture recognizer the same way you would connect a button.

Add the code from Marmor in the the action handler

- (IBAction)handleLongPress:(UILongPressGestureRecognizer *)sender {
if (sender.state == UIGestureRecognizerStateBegan) {

    CGPoint p = [sender locationInView:self.tableView];

    NSIndexPath *indexPath = [self.tableView indexPathForRowAtPoint:p];
    if (indexPath == nil) {
        NSLog(@"long press on table view but not on a row");
    } else {
        UITableViewCell *cell = [self.tableView cellForRowAtIndexPath:indexPath];
        if (cell.isHighlighted) {
            NSLog(@"long press on table view at section %d row %d", indexPath.section, indexPath.row);
        }
    }
}

}

In case you want to replace values in place, you can update your original list with values from a list comprehension by assigning to the whole slice of the original.

data = [*range(11)] # [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
id_before = id(data)
data[:] = [x if x % 2 else None for x in data]
data
# Out: [None, 1, None, 3, None, 5, None, 7, None, 9, None]
id_before == id(data)  # check if list is still the same
# Out: True

If you have multiple names pointing to the original list, for example you wrote data2=data before changing the list and you skip the slice notation for assigning to data, data will rebind to point to the newly created list while data2 still points to the original unchanged list.

data = [*range(11)] # [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]
data2 = data
id_before = id(data)
data = [x if x % 2 else None for x in data]  # no [:] here
data
# Out: [None, 1, None, 3, None, 5, None, 7, None, 9, None]
id_before == id(data)  # check if list is still the same
# Out: False
data2
# Out: [0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10]

Note: This is no recommendation for generally preferring one over the other (changing list in place or not), but behavior you should be aware of.

found the easy way.. round imageview with user define radius:

http://shortcutsandroid.blogspot.in/2015/02/round-image-view-in-android.html

just add imageView.setRadius();

//it will set radius for the round imageView.

Update Model from Database doesn't works for me.

I had to remove the conflicted entity, then execute Update Model from Database, lastly rebuild the solution. After that, everything works fine.

When you try to set text in Edittext or textview you should pass only String format.

dateTime.setText(app.getTotalDl());

to

dateTime.setText(String.valueOf(app.getTotalDl()));

I totally missed the export button at the bottom of each visualization. As for read only access...Shield from Elasticsearch might be worth exploring.

Just in case someone else runs into this problem I solved it by the following

brew update && brew upgrade # installs libpng 1.6

This caused an error with other packages requiring 1.5 which they were built with, so I linked it:

cd /usr/local/lib/
ln -s ../Cellar/libpng/1.5.18/lib/libpng15.15.dylib

Now they are both living in harmony and side by side for the different packages. It would be better to rebuild the packages that depend on 1.5, but this works as a quick bandage fix.

You can set the System properties as VM arguments.

If your project is a maven project then you can execute following command while running the test class:

mvn test -Dapp.url="https://stackoverflow.com"

Test class:

public class AppTest  {
@Test
public void testUrl() {
    System.out.println(System.getProperty("app.url"));
    }
}

If you want to run individual test class or method in eclipse then :

1) Go to Run -> Run Configuration

2) On left side select your Test class under the Junit section.

3) do the following :

I wrote this JS function dump() to work like PHP's var_dump(). To show the contents of the variable in an alert window: dump(variable) To show the contents of the variable in the web page: dump(variable, 'body') To just get a string of the variable: dump(variable, 'none')

/* repeatString() returns a string which has been repeated a set number of times */
function repeatString(str, num) {
    out = '';
    for (var i = 0; i < num; i++) {
        out += str;

/*
dump() displays the contents of a variable like var_dump() does in PHP. dump() is
better than typeof, because it can distinguish between array, null and object.
Parameters:

Return Value:
    A string of the variable's contents
Limitations:
    Can't pass an undefined variable to dump(). 
    dump() can't distinguish between int and float.
    dump() can't tell the original variable type of a member variable of an object.
    These limitations can't be fixed because these are *features* of JS. However, dump()

Here is a function that will convert a string to an array, even if there is only one item in the list (no separator character):

function listToAray(fullString, separator) {
  var fullArray = [];

  if (fullString !== undefined) {
    if (fullString.indexOf(separator) == -1) {
      fullAray.push(fullString);
    } else {
      fullArray = fullString.split(separator);
    }
  }

  return fullArray;
}

Use it like this:

var myString = 'alpha,bravo,charlie,delta';
var myArray = listToArray(myString, ',');
myArray[2]; // charlie

var yourString = 'echo';
var yourArray = listToArray(yourString, ',');
yourArray[0]; // echo

I created this function because split throws out an error if there isn't any separator character in the string (only one item).

If you can use JQuery, then using the JQuery :focus selector will do the needful

$(this).is(':focus');

Already answered, but to generalize to help other readers:

    //Here:   NSData * fileData;
    uint8_t * bytePtr = (uint8_t  * )[fileData bytes];

    // Here, For getting individual bytes from fileData, uint8_t is used.
    // You may choose any other data type per your need, eg. uint16, int32, char, uchar, ... .
    // Make sure, fileData has atleast number of bytes that a single byte chunk would need. eg. for int32, fileData length must be > 4 bytes. Makes sense ?

    // Now, if you want to access whole data (fileData) as an array of uint8_t
    NSInteger totalData = [fileData length] / sizeof(uint8_t);

    for (int i = 0 ; i < totalData; i ++)
    {
        NSLog(@"data byte chunk : %x", bytePtr[i]);
    }

I had a similar problem. This helps me across main email clients. Add:

• attributes cellpadding="0", cellspacing="0" and border="0" to tables
• style border-collapse: collapse; to tables
• styles padding: 0; margin: 0; to each element
• and styles font-size: 0px; line-height: 0px; to each element which is empty

I have had this problem on multiple projects converting Excel 2000 to 2010. Here is what I found which seems to be working. I made two changes, but not sure which caused the success:

1) I changed how I closed and saved the file (from close & save = true to save as the same file name and close the file:

...
    Dim oFile           As Object       ' File being processed
...
[Where the error happens - where aArray(i) is just the name of an Excel.xlsb file]
   Set oFile = GetObject(aArray(i))
...
'oFile.Close SaveChanges:=True    - OLD CODE WHICH ERROR'D
'New Code
oFile.SaveAs Filename:=oFile.Name
oFile.Close SaveChanges:=False

2) I went back and looked for all of the .range in the code and made sure it was the full construct..

Application.Workbooks("workbook name").Worksheets("worksheet name").Range("G19").Value

or (not 100% sure if this is correct syntax, but this is the 'effort' i made)

ActiveSheet.Range("A1").Select

I made curl

I founded the curl project back in 1998, I wrote the initial curl version and I created libcurl. I've written more than half of all the 24,000 commits done in the source code repository up to this point in time. I'm still the lead developer of the project. To a large extent, curl is my baby.

I shipped the first version of curl as open source since I wanted to "give back" to the open source world that had given me so much code already. I had used so much open source and I wanted to be as cool as the other open source authors.

Thanks to it being open source, literally thousands of people have been able to help us out over the years and have improved the products, the documentation. the web site and just about every other detail around the project. curl and libcurl would never have become the products that they are today were they not open source. The list of contributors now surpass 1900 names and currently the list grows with a few hundred names per year.

Thanks to curl and libcurl being open source and liberally licensed, they were immediately adopted in numerous products and soon shipped by operating systems and Linux distributions everywhere thus getting a reach beyond imagination.

Thanks to them being "everywhere", available and liberally licensed they got adopted and used everywhere and by everyone. It created a defacto transfer library standard.

At an estimated six billion installations world wide, we can safely say that curl is the most widely used internet transfer library in the world. It simply would not have gone there had it not been open source. curl runs in billions of mobile phones, a billion Windows 10 installations, in a half a billion games and several hundred million TVs - and more.

Should I have released it with proprietary license instead and charged users for it? It never occured to me, and it wouldn't have worked because I would never had managed to create this kind of stellar project on my own. And projects and companies wouldn't have used it.

Why do I still work on curl?

Now, why do I and my fellow curl developers still continue to develop curl and give it away for free to the world?

1. I can't speak for my fellow project team members. We all participate in this for our own reasons.
2. I think it's still the right thing to do. I'm proud of what we've accomplished and I truly want to make the world a better place and I think curl does its little part in this.
3. There are still bugs to fix and features to add!
4. curl is free but my time is not. I still have a job and someone still has to pay someone for me to get paid every month so that I can put food on the table for my family. I charge customers and companies to help them with curl. You too can get my help for a fee, which then indirectly helps making sure that curl continues to evolve, remain free and the kick-ass product it is.
5. curl was my spare time project for twenty years before I started working with it full time. I've had great jobs and worked on awesome projects. I've been in a position of luxury where I could continue to work on curl on my spare time and keep shipping a quality product for free. My work on curl has given me friends, boosted my career and taken me to places I would not have been at otherwise.
6. I would not do it differently if I could back and do it again.

Am I proud of what we've done?

Yes. So insanely much.

But I'm not satisfied with this and I'm not just leaning back, happy with what we've done. I keep working on curl every single day, to improve, to fix bugs, to add features and to make sure curl keeps being the number one file transfer solution for the world even going forward.

We do mistakes along the way. We make the wrong decisions and sometimes we implement things in crazy ways. But to win in the end and to conquer the world is about patience and endurance and constantly going back and reconsidering previous decisions and correcting previous mistakes. To continuously iterate, polish off rough edges and gradually improve over time.

Never give in. Never stop. Fix bugs. Add features. Iterate. To the end of time.

For real?

Yeah. For real.

Do I ever get tired? Is it ever done?

Sure I get tired at times. Working on something every day for over twenty years isn't a paved downhill road. Sometimes there are obstacles. During times things are rough. Occasionally people are just as ugly and annoying as people can be.

But curl is my life's project and I have patience. I have thick skin and I don't give up easily. The tough times pass and most days are awesome. I get to hang out with awesome people and the reward is knowing that my code helps driving the Internet revolution everywhere is an ego boost above normal.

curl will never be "done" and so far I think work on curl is pretty much the most fun I can imagine. Yes, I still think so even after twenty years in the driver's seat. And as long as I think it's fun I intend to keep at it.

We had the same problem when making our API as well. We were looking for an HTTP status code equivalent to an InvalidArgumentException. After reading the source article below, we ended up using 422 Unprocessable Entity which states:

The 422 (Unprocessable Entity) status code means the server understands the content type of the request entity (hence a 415 (Unsupported Media Type) status code is inappropriate), and the syntax of the request entity is correct (thus a 400 (Bad Request) status code is inappropriate) but was unable to process the contained instructions. For example, this error condition may occur if an XML request body contains well-formed (i.e., syntactically correct), but semantically erroneous, XML instructions.

To use Collections sort(List,Comparator) , you need to create a class that implements Comparator Interface, and code for the compare() in it, through Comparator Interface

You can do something like this:

class StudentComparator implements Comparator
{
    public int compare (Student s1 Student s2)
    {
        // code to compare 2 students
    }
}

To sort do this:

 Collections.sort(List,new StudentComparator())

The problem is that you have a date formatted like this:

Thu Jun 18 20:56:02 EDT 2009

But are using a SimpleDateFormat that is:

yyyy-MM-dd

The two formats don't agree. You need to construct a SimpleDateFormat that matches the layout of the string you're trying to parse into a Date. Lining things up to make it easy to see, you want a SimpleDateFormat like this:

EEE MMM dd HH:mm:ss zzz yyyy
Thu Jun 18 20:56:02 EDT 2009

Check the JavaDoc page I linked to and see how the characters are used.

here is my solution in java using linkedlist.

class queue<T>{
static class Node<T>{
    private T data;
    private Node<T> next;
    Node(T data){
        this.data = data;
        next = null;
    }
}
Node firstTop;
Node secondTop;

void push(T data){
    Node temp = new Node(data);
    temp.next = firstTop;
    firstTop = temp;
}

void pop(){
    if(firstTop == null){
        return;
    }
    Node temp = firstTop;
    while(temp != null){
        Node temp1 = new Node(temp.data);
        temp1.next = secondTop;
        secondTop = temp1;
        temp = temp.next;
    }
    secondTop = secondTop.next;
    firstTop = null;
    while(secondTop != null){
        Node temp3 = new Node(secondTop.data);
        temp3.next = firstTop;
        firstTop = temp3;
        secondTop = secondTop.next;
    }
}

}

Note : In this case, pop operation is very time consuming. So i won't suggest to create a queue using two stack.

Just change filter to omitBy

const data = { aaa: 111, abb: 222, bbb: 333 };_x000D_
const result = _.omitBy(data, (value, key) => !key.startsWith("a"));_x000D_
console.log(result);

<script src="https://cdnjs.cloudflare.com/ajax/libs/lodash.js/4.17.15/lodash.min.js"></script>

I think add if (this.readyState == 4 && this.status == 200) to wait is better:

var xhttp = new XMLHttpRequest();
xhttp.onreadystatechange = function() {
    if (this.readyState == 4 && this.status == 200) {
       // Typical action to be performed when the document is ready:
        var response = xhttp.responseText;
        console.log("ok"+response);
    }
};
xhttp.open("GET", "your url", true);

xhttp.send();

Keep in mind that international users may be using a decimal separator other than . in which case values can get mixed up or just become nil when using intValue on a string.

For example, in the UK 1.23 is written 1,23, so the number 1.777 would be input by user as 1,777, which, as .intValue, will be 1777 not 1 (truncated).

I've made a macro that will convert input text to an NSNumber based on a locale argument which can be nil (if nil it uses device current locale).

#define stringToNumber(__string, __nullable_locale) (\
(^NSNumber *(void){\
NSLocale *__locale = __nullable_locale;\
if (!__locale) {\
__locale = [NSLocale currentLocale];\
}\
NSString *__string_copy = [__string stringByReplacingOccurrencesOfString:__locale.groupingSeparator withString:@""];\
__string_copy = [__string_copy stringByReplacingOccurrencesOfString:__locale.decimalSeparator withString:@"."];\
return @([__string_copy doubleValue]);\
})()\
)

<graphics.h> is not a standard header. Most commonly it refers to the header for Borland's BGI API for DOS and is antiquated at best.

However it is nicely simple; there is a Win32 implementation of the BGI interface called WinBGIm. It is implemented using Win32 GDI calls - the lowest level Windows graphics interface. As it is provided as source code, it is perhaps a simple way of understanding how GDI works.

WinBGIm however is by no means cross-platform. If all you want are simple graphics primitives, most of the higher level GUI libraries such as wxWidgets and Qt support that too. There are simpler libraries suggested in the possible duplicate answers mentioned in the comments.

I tried to delete a column while using the package data.table and got an unexpected result. I kind of think the following might be worth posting. Just a little cautionary note.

[ Edited by Matthew ... ]

DF = read.table(text = "

     apples Ohio   aa    500   100   55

     apples Ohio   cc    700     0   33
     apples Ohio   dd    300    50   66
", sep = "", header = TRUE, stringsAsFactors = FALSE)

DF[ , !names(DF) %in% c("grade")]   # all columns other than 'grade'
   fruit state y1980 y1990 y2000
1 apples  Ohio   500   100    55
2 apples  Ohio     0     0    44
3 apples  Ohio   700     0    33
4 apples  Ohio   300    50    66

library('data.table')
DT = as.data.table(DF)

DT[ , !names(dat4) %in% c("grade")]    # not expected !! not the same as DF !!
[1]  TRUE  TRUE FALSE  TRUE  TRUE  TRUE

DT[ , !names(DT) %in% c("grade"), with=FALSE]    # that's better
    fruit state y1980 y1990 y2000
1: apples  Ohio   500   100    55

3: apples  Ohio   700     0    33
4: apples  Ohio   300    50    66

Basically, the syntax for data.table is NOT exactly the same as data.frame. There are in fact lots of differences, see FAQ 1.1 and FAQ 2.17. You have been warned!

This is my gradle.properties, please note those HTTPS portion

Although, there are many useful answers. Whereas, just to add another way to it. You can also use

git shortlog --author="<author name>" --format="%h %s"

It will show the output in the grouped manner:

<Author Name> (5):
  4da3975f dependencies upgraded
  49172445 runtime dependencies resolved
  bff3e127 user-service, kratos, and guava dependencies upgraded
  414b6f1e dropwizard :- service, rmq and db-sharding depedencies upgraded
  a96af8d3 older dependecies removed

Here, total of 5 commits are done by <Author Name> under the current branch. Whereas, you can also use --all to enforce the search everywhere (all the branches) in the git repository.

One catch: git internally tries to match an input <author name> with the name and email of the author in the git database. It is case-sensitive.

You might try: org.apache.commons.httpclient.util.URIUtil.encodeQuery in Apache commons-httpclient project

Like this (see URIUtil):

URIUtil.encodeQuery("http://www.google.com?q=a b")

will become:

http://www.google.com?q=a%20b

You can of course do it yourself, but URI parsing can get pretty messy...

If you're using chained syntax:

$(".class").each(function() {
    // ...
});

...I don't think there's any (reasonable) way for the code within the each function to know how many items there are. (Unreasonable ways would involve repeating the selector and using index.)

But it's easy enough to make the collection available to the function that you're calling in each. Here's one way to do that:

var collection = $(".class");
collection.each(function() {
    // You can access `collection.length` here.
});

As a somewhat convoluted option, you could convert your jQuery object to an array and then use the array's forEach. The arguments that get passed to forEach's callback are the entry being visited (what jQuery gives you as this and as the second argument), the index of that entry, and the array you called it on:

$(".class").get().forEach(function(entry, index, array) {
    // Here, array.length is the total number of items
});

That assumes an at least vaguely modern JavaScript engine and/or a shim for Array#forEach.

Or for that matter, give yourself a new tool:

// Loop through the jQuery set calling the callback:
//    loop(callback, thisArg);
// Callback gets called with `this` set to `thisArg` unless `thisArg`
// is falsey, in which case `this` will be the element being visited.
// Arguments to callback are `element`, `index`, and `set`, where
// `element` is the element being visited, `index` is its index in the
// set, and `set` is the jQuery set `loop` was called on.
// Callback's return value is ignored unless it's `=== false`, in which case
// it stops the loop.
$.fn.loop = function(callback, thisArg) {
    var me = this;
    return this.each(function(index, element) {
        return callback.call(thisArg || element, element, index, me);
    });
};

Usage:

$(".class").loop(function(element, index, set) {
    // Here, set.length is the length of the set
});

If you want to set the background using a hex color you could do this:

var bc = new BrushConverter();

myTextBox.Background = (Brush)bc.ConvertFrom("#FFXXXXXX");

Or you could set up a SolidColorBrush resource in XAML, and then use findResource in the code-behind:

<SolidColorBrush x:Key="BrushFFXXXXXX">#FF8D8A8A</SolidColorBrush>
myTextBox.Background = (Brush)Application.Current.MainWindow.FindResource("BrushFFXXXXXX");

You can validate group checkbox and radio button without extra js code, see below example.

Your JS should be look like:

$("#formid").validate();

You can play with HTML tag and attributes: eg. group checkbox [minlength=2 and maxlength=4]

<fieldset class="col-md-12">
  <legend>Days</legend>
  <div class="form-row">
    <div class="col-12 col-md-12 form-group">
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="1" required="required" data-msg-required="This value is required." minlength="2" maxlength="4" data-msg-maxlength="Max should be 4">Monday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="2">Tuesday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="3">Wednesday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="4">Thursday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="5">Friday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="6">Saturday
        </label>
        <label class="checkbox-inline">
          <input type="checkbox" name="daysgroup[]" value="7">Sunday
        </label>
        <label for="daysgroup[]" class="error">Your error message will be display here.</label>
    </div>
  </div>
</fieldset>

You can see here first or any one input should have required, minlength="2" and maxlength="4" attributes. minlength/maxlength as per your requirement.

eg. group radio button:

<fieldset class="col-md-12">
  <legend>Gender</legend>
  <div class="form-row">
    <div class="col-12 col-md-12 form-group">
        <label class="form-check-inline">
          <input type="radio" name="gendergroup[]" value="m" required="required" data-msg-required="This value is required.">man
        </label>
        <label class="form-check-inline">
          <input type="radio" name="gendergroup[]" value="w">woman
        </label>
        <label class="form-check-inline">
          <input type="radio" name="gendergroup[]" value="o">other
        </label>
        <label for="gendergroup[]" class="error">Your error message will be display here.</label>
    </div>
  </div>
</fieldset>

Object.keys(data.shareInfo[i]).length

The C/A Browser forum sets what is and is not valid in a certificate, and what CA's should reject.

According to their Baseline Requirements for the Issuance and Management of Publicly-Trusted Certificates document, CAs must, since 2015, not issue certificats where the common name, or common alternate names fields contains a reserved IP or internal name, where reserved IP addresses are IPs that IANA has listed as reserved - which includes all NAT IPs - and internal names are any names that don't resolve on the public DNS.

Public IP addresses CAN be used (and the baseline requirements doc specifies what kinds of checks a CA must perform to ensure the applicant owns the IP).

The simplest way is to use the following pattern:

http://[server]/[site]/[ListName]/[Folder]/[SubFolder]

To place a shortcut to a document library:

1. Upload it as *.url file. However, by default, this file type is not allowed.
2. Go to you Document Library settings > Advanced Settings > Allow management of content types. Add the "Link to document" content type to a document library and paste the link

Pandas 0.21 now has an axis parameter

The rename method has gained an axis parameter to match most of the rest of the pandas API.

So, in addition to this:

df.rename(columns = {'two':'new_name'})

You can do:

df.rename({'two':'new_name'}, axis=1)

or

df.rename({'two':'new_name'}, axis='columns')

If the file you are working on is not so big, and temporarily storing it in a variable is no problem, then you can use Bash string substitution on the whole file at once - there's no need to go over it line by line:

file_contents=$(</tmp/file.txt)
echo "${file_contents//abc/XYZ}" > /tmp/file.txt

The whole file contents will be treated as one long string, including linebreaks.

XYZ can be a variable eg $replacement, and one advantage of not using sed here is that you need not be concerned that the search or replace string might contain the sed pattern delimiter character (usually, but not necessarily, /). A disadvantage is not being able to use regular expressions or any of sed's more sophisticated operations.

rake db:migrate:down VERSION=your_migrations's_version_number_here

The version is the numerical prefix on the migration's file name

How to find version:

Your migration files are stored in your rails_root/db/migrate directory. Find appropriate file up to which you want to rollback and copy the prefix number.

for example

file name: 20140208031131_create_roles.rb then the version is 20140208031131

Sometimes you need to include mysql db port id in the server like so.

$serverName = "127.0.0.1:3307";

If using virtualenv, look for the build directory under your environments root.

I would:

for _ in range(3):
    do()

The _ is convention for a variable whose value you don't care about.

You might also see some people write:

[do() for _ in range(3)]

however that is slightly more expensive because it creates a list containing the return values of each invocation of do() (even if it's None), and then throws away the resulting list. I wouldn't suggest using this unless you are using the list of return values.

The particular format for strptime:

datetime.datetime.strptime(string_date, "%Y-%m-%d %H:%M:%S.%f")
#>>> datetime.datetime(2013, 9, 28, 20, 30, 55, 782000)

I'd do it this way:

from os.path import abspath, exists

f_path = abspath("fooabar.txt")

if exists(f_path):
    with open(f_path) as f:
        print f.read()

The above code builds an absolute path to the file using abspath and is equivalent to using normpath(join(os.getcwd(), path)) [that's from the pydocs]. It then checks if that file actually exists and then uses a context manager to open it so you don't have to remember to call close on the file handle. IMHO, doing it this way will save you a lot of pain in the long run.

According to HTML living standard specification, the load event is

Fired at the Window when the document has finished loading; fired at an element containing a resource (e.g. img, embed) when its resource has finished loading

I.e. load event is not fired on document object.

It's trying to connect to the computer it's running on on port 5000, but the connection is being refused. Are you sure you have a server running?

If not, you can use netcat for testing:

nc -l -k -p 5000

Some implementations may require you to omit the -p flag.

Just met one special case that I had to use easy_install instead of pip, or I have to pull the source codes directly.

For the package GitPython, the version in pip is too old, which is 0.1.7, while the one from easy_install is the latest which is 0.3.2.rc1.

I'm using Python 2.7.8. I'm not sure about the underlay mechanism of easy_install and pip, but at least the versions of some packages may be different from each other, and sometimes easy_install is the one with newer version.

easy_install GitPython

It worked for me

A Redirect can only happen if the first line in an HTTP message is "HTTP/1.x 3xx Redirect Reason".

If you already called Response.Write() or set some headers, it'll be too late for a redirect. You can try calling Response.Headers.Clear() before the Redirect to see if that helps.

You can't. It's immediate mode graphics. But you can sort of simulate it by drawing a rectangle over it in the background color with an opacity.

If the image is over something other than a constant color, then it gets quite a bit trickier. You should be able to use the pixel manipulation methods in this case. Just save the area before drawing the image, and then blend that back on top with an opacity afterwards.

Complete snippet would look like the following. It expands @mouad's answer to asserting on error's message (or generally str representation of its args), which may be useful.

Switch to the develop branch:

$ git checkout develop

Creates feature/foo branch of develop.

$ git checkout -b feature/foo develop

merge the changes to develop without a fast-forward

$ git checkout develop
$ git merge --no-ff myFeature

Now push changes to the server

$ git push origin develop
$ git push origin feature/foo

You can only add folders or jar files to a class loader. So if you have a single class file, you need to put it into the appropriate folder structure first.

Here is a rather ugly hack that adds to the SystemClassLoader at runtime:

import java.io.IOException;
import java.io.File;
import java.net.URLClassLoader;
import java.net.URL;
import java.lang.reflect.Method;

public class ClassPathHacker {

  private static final Class[] parameters = new Class[]{URL.class};

  public static void addFile(String s) throws IOException {
    File f = new File(s);
    addFile(f);
  }//end method

  public static void addFile(File f) throws IOException {
    addURL(f.toURL());
  }//end method


  public static void addURL(URL u) throws IOException {

    URLClassLoader sysloader = (URLClassLoader) ClassLoader.getSystemClassLoader();
    Class sysclass = URLClassLoader.class;

    try {
      Method method = sysclass.getDeclaredMethod("addURL", parameters);
      method.setAccessible(true);
      method.invoke(sysloader, new Object[]{u});
    } catch (Throwable t) {
      t.printStackTrace();
      throw new IOException("Error, could not add URL to system classloader");
    }//end try catch

   }//end method

}//end class

The reflection is necessary to access the protected method addURL. This could fail if there is a SecurityManager.

I suggest you cast all columns before you concat them

cast('data1' as varchar) + cast('data2' as varchar) + cast('data3' as varchar)

This should work for you.

Adding an answer related to child_process.exec as I too had needed live feedback and wasn't getting any until after the script finished. This also supplements my comment to the accepted answer, but as it's formatted it will a bit more understandable and easier to read.

Basically, I have a npm script that calls Gulp, invoking a task which subsequently uses child_process.exec to execute a bash or batch script depending on the OS. Either script runs a build process via Gulp and then makes some calls to some binaries that work with the Gulp output.

It's exactly like the others (spawn, etc.), but for the sake of completion, here's exactly how to do it:

// INCLUDES
import * as childProcess from 'child_process'; // ES6 Syntax


// GLOBALS
let exec = childProcess.exec; // Or use 'var' for more proper 
                              // semantics, though 'let' is 
                              // true-to-scope


// Assign exec to a variable, or chain stdout at the end of the call
// to exec - the choice, yours (i.e. exec( ... ).stdout.on( ... ); )
let childProcess = exec
(
    './binary command -- --argument argumentValue',
    ( error, stdout, stderr ) =>
    {
        if( error )
        {
            // This won't show up until the process completes:
            console.log( '[ERROR]: "' + error.name + '" - ' + error.message );
            console.log( '[STACK]: ' + error.stack );

            console.log( stdout );
            console.log( stderr );
            callback();            // Gulp stuff
            return;
        }

        // Neither will this:
        console.log( stdout );
        console.log( stderr );
        callback();                // Gulp stuff
    }
);

Now its as simple as adding an event listener. For stdout:

childProcess.stdout.on
(
    'data',
    ( data ) =>
    {
        // This will render 'live':
        console.log( '[STDOUT]: ' + data );
    }
);

And for stderr:

childProcess.stderr.on
(
    'data',
    ( data ) =>
    {
        // This will render 'live' too:
        console.log( '[STDERR]: ' + data );
    }
);

Not too bad at all - HTH

double d = 14.4;
if((d-(int)d)!=0)
    System.out.println("decimal value is there");
else
    System.out.println("decimal value is not there");

Here's what I get.

I'm using Visual Studio Code and its Terminal to execute the 'npm' commands.

Visual Studio Code (not as administrator)
PS g:\labs\myproject> npm install bootstrap@3

Results in scandir and/or permission errors.

Visual Studio Code (as Administrator)
Run this command after I've run something like 'ng serve'

PS g:\labs\myproject> npm install bootstrap@3

Results in scandir and/or permission errors.

Visual Studio Code (as Administrator - closing and opening the IDE)
If I have already executed other commands that would impact node modules I decided to try closing Visual Studio Code first, opening it up as Administrator then running the command:

PS g:\labs\myproject> npm install bootstrap@3

Result I get then is: + [email protected]
added 115 packages and updated 1 package in 24.685s

This is not a permanent solution since I don't want to continue closing down VS Code every time I want to execute an npm command, but it did resolve the issue to a point.

I had the same problem. Check out the comment in https://gist.github.com/khernyo/4226923#comment-812526

It says:

for gradle android plugin v0.3 use "com.android.build.gradle.tasks.PackageApplication"

That should fix your problem.

With google-drive-ftp-adapter I have been able to access the My Drive area of Google Drive with the FileZilla FTP client. However, I have not been able to access the Shared with me area.

You can configure which Google account credentials it uses by changing the account property in the configuration.properties file from default to the desired Google account name. See the instructions at http://www.andresoviedo.org/google-drive-ftp-adapter/

If you can expect the browser's open/save interface to pop up for the user once the download is complete, then you can run this when you start the download:

$( document ).blur( function () {
    // Your code here...
});

When the dialogue pops up on top of the page, the blur event will trigger.

        $out[$index] = ( is_object ( $node ) ) ? xml2array ( $node ) : $node;

It could help you. However, if you convert XML to an array you will loose all attributes that might be present, so you cannot go back to XML and get the same XML.

I know that I have this problem over and over when I deploy my application on a new server because I'm using this driver to connect to a Excel file. So here it is what I'm doing lately.

There's a Windows Server 2008 R2, I install the Access drivers for a x64 bit machine and I get rid of this message, which makes me very happy just to bump into another.

This one here below works splendidly on my dev machine but on server gives me an error even after installing the latest ODBC drivers, which I think this is the problem, but this is how I solved it.

private const string OledbProviderString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\\OlsonWindows.xls;Extended Properties=\"Excel 8.0;HDR=YES\"";

I replace with the new provider like this below:

private const string OledbProviderString = @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\OlsonWindows.xlsx;Extended Properties='Excel 12.0;HDR=YES;';";

But as I do this, there's one thing you should notice. Using the .xlsx file extension and Excel version is 12.0.

After I get into this error message Error: "Could Not Find Installable ISAM", I decide to change the things a little bit like below:

private const string OledbProviderString =      @"Provider=Microsoft.ACE.OLEDB.12.0;Data Source=|DataDirectory|\OlsonWindows.xls;Extended Properties='Excel 8.0;HDR=YES;';"; 

and yes, I'm done with that nasty thing, but here I got another message The Microsoft Access database engine cannot open or write to the file 'time_zone'. It is already opened exclusively by another user, or you need permission to view and write its data. which tells me I'm not far away from solving it.

Maybe there's another process that opened the file meanwhile and all that I have to do is a restart and all will take start smoothly running as expected.

I believe your problem is that you are passing testFunct a string, and not a function object, (is that even possible?)

See this article for tips on how to help performance issues. This includes both performance issues related to starting up, under the "cold start" section. Most of this will matter no matter what type of server you are using, locally or in production.

If the application deserializes anything from XML (and that includes web services…) make sure SGEN is run against all binaries involved in deseriaization and place the resulting DLLs in the Global Assembly Cache (GAC). This precompiles all the serialization objects used by the assemblies SGEN was run against and caches them in the resulting DLL. This can give huge time savings on the first deserialization (loading) of config files from disk and initial calls to web services. http://msdn.microsoft.com/en-us/library/bk3w6240(VS.80).aspx

If any IIS servers do not have outgoing access to the internet, turn off Certificate Revocation List (CRL) checking for Authenticode binaries by adding generatePublisherEvidence=”false” into machine.config. Otherwise every worker processes can hang for over 20 seconds during start-up while it times out trying to connect to the internet to obtain a CRL list. http://blogs.msdn.com/amolravande/archive/2008/07/20/startup-performance-disable-the-generatepublisherevidence-property.aspx

http://msdn.microsoft.com/en-us/library/bb629393.aspx

Consider using NGEN on all assemblies. However without careful use this doesn’t give much of a performance gain. This is because the base load addresses of all the binaries that are loaded by each process must be carefully set at build time to not overlap. If the binaries have to be rebased when they are loaded because of address clashes, almost all the performance gains of using NGEN will be lost. http://msdn.microsoft.com/en-us/magazine/cc163610.aspx

This solution seems easy to follow:

public static bool isValidURL(string url) {
    WebRequest webRequest = WebRequest.Create(url);
    WebResponse webResponse;
    try
    {
        webResponse = webRequest.GetResponse();
    }
    catch //If exception thrown then couldn't get response from address
    {
        return false ;
    }
    return true ;
}

How about this?

val a = Array("One", "Two", "Three")
a.foldLeft(0) ((i, x) => {println(i + ": " + x); i + 1;} )

Output:

0: One
1: Two
2: Three

What about:

round(n,1)+epsilon

Branches in SVN are essentially directories; you don't name the branch so much as choose the name of the directory to branch into.

The common way of 'naming' a branch is to place it under a directory called branches in your repository. In the "To URL:" portion of TortoiseSVN's Branch dialog, you would therefore enter something like:

(svn/http)://path-to-repo/branches/your-branch-name

The main branch of a project is referred to as the trunk, and is usually located in:

(svn/http)://path-to-repo/trunk

Motivation

Sometimes I have been getting some errors when you want to pass httpBody serialized to Data from Dictionary, which on most cases is due to the wrong encoding or malformed data due to non NSCoding conforming objects in the Dictionary.

Solution

Depending on your requirements one easy solution would be to create a String instead of Dictionary and convert it to Data. You have the code samples below written on Objective-C and Swift 3.0.

Objective-C

// Create the URLSession on the default configuration
NSURLSessionConfiguration *defaultSessionConfiguration = [NSURLSessionConfiguration defaultSessionConfiguration];
NSURLSession *defaultSession = [NSURLSession sessionWithConfiguration:defaultSessionConfiguration];

// Setup the request with URL
NSURL *url = [NSURL URLWithString:@"yourURL"];
NSMutableURLRequest *urlRequest = [NSMutableURLRequest requestWithURL:url];

// Convert POST string parameters to data using UTF8 Encoding
NSString *postParams = @"api_key=APIKEY&[email protected]&password=password";
NSData *postData = [postParams dataUsingEncoding:NSUTF8StringEncoding];

// Convert POST string parameters to data using UTF8 Encoding
[urlRequest setHTTPMethod:@"POST"];
[urlRequest setHTTPBody:postData];

// Create dataTask
NSURLSessionDataTask *dataTask = [defaultSession dataTaskWithRequest:urlRequest completionHandler:^(NSData *data, NSURLResponse *response, NSError *error) {
    // Handle your response here
}];

// Fire the request
[dataTask resume];

Swift

// Create the URLSession on the default configuration
let defaultSessionConfiguration = URLSessionConfiguration.default
let defaultSession = URLSession(configuration: defaultSessionConfiguration)

// Setup the request with URL
let url = URL(string: "yourURL")
var urlRequest = URLRequest(url: url!)  // Note: This is a demo, that's why I use implicitly unwrapped optional

// Convert POST string parameters to data using UTF8 Encoding
let postParams = "api_key=APIKEY&[email protected]&password=password"
let postData = postParams.data(using: .utf8)

// Set the httpMethod and assign httpBody
urlRequest.httpMethod = "POST"
urlRequest.httpBody = postData

// Create dataTask
let dataTask = defaultSession.dataTask(with: urlRequest) { (data, response, error) in
    // Handle your response here
}

// Fire the request
dataTask.resume()

In SWT you need not be in a listener to get at the mouse location. The Display object has the method getCursorLocation().

In vanilla SWT/JFace, call Display.getCurrent().getCursorLocation().

In an RCP application, call PlatformUI.getWorkbench().getDisplay().getCursorLocation().

For SWT applications, it is preferable to use getCursorLocation() over the MouseInfo.getPointerInfo() that others have mentioned, as the latter is implemented in the AWT toolkit that SWT was designed to replace.

Try this:

if (value instanceof Array) {
alert('value is Array!');
} else {
alert('Not an array');
}

If you are simply looking for producing a binary executable from a PHP script, then please avoid trying to make your question extremely precise because it will make it appear that you know exactly what you need. Besides, most PHP developer have absolutely zero clue about what a bytecode is.

With that said, the answers is YES. I have just finished compiling a PHP script into a binary. And not just any binary. I have used the CDE application (link to Wayback Machine, the original link is now broken) to turn it into an portable binary that can be distributed with all the dependencies and executed without any issue… and it works beautifully.

All you need is to use phc.

From a module:

UserFormName.UserForm_Initialize

Just make sure that in your userform, you update the sub like so:

Public Sub UserForm_Initialize() so it can be called from outside the form.

Alternately, if the Userform hasn't been loaded:

UserFormName.Show will end up calling UserForm_Initialize because it loads the form.

A li doesn't have a value. Only form-related elements such as input, textarea and select have values.

Some browsers repeat the thead element on each page, as they are supposed to. Others need some help: Add this to your CSS:

thead {display: table-header-group;}
tfoot {display: table-header-group;}

Opera 7.5 and IE 5 won't repeat headers no matter what you try.

Here is a new way to work with SQL views in EF Core: Query Types.

I hope this one might help you.

let data = [];
data[0] = { "ID": "1", "Status": "Valid" };
data[1] = { "ID": "2", "Status": "Invalid" };

let tempData = [];

tempData= data.filter((item)=>item.Status!='Invalid')

console.log(tempData)

Why not update the files on the local file system instead? You can read/write files into your applications sandboxed area.

http://developer.android.com/guide/topics/data/data-storage.html#filesInternal

Other alternatives you may want to look into are Shared Perferences and using Cache Files (all described at the link above)

Using a instead of w should let you update the file instead of creating a new one/overwriting everything in the existing file.

See this answer for a difference in the modes.

You may have moved on by now, but... as far as I know there's no way to delete a history entry (or state).

One option I've been looking into is to handle the history yourself in JavaScript and use the window.history object as a carrier of sorts.

Basically, when the page first loads you create your custom history object (we'll go with an array here, but use whatever makes sense for your situation), then do your initial pushState. I would pass your custom history object as the state object, as it may come in handy if you also need to handle users navigating away from your app and coming back later.

var myHistory = [];

function pageLoad() {
    window.history.pushState(myHistory, "<name>", "<url>");

    //Load page data.
}

Now when you navigate, you add to your own history object (or don't - the history is now in your hands!) and use replaceState to keep the browser out of the loop.

function nav_to_details() {
    myHistory.push("page_im_on_now");
    window.history.replaceState(myHistory, "<name>", "<url>");

    //Load page data.
}

When the user navigates backwards, they'll be hitting your "base" state (your state object will be null) and you can handle the navigation according to your custom history object. Afterward, you do another pushState.

function on_popState() {
    // Note that some browsers fire popState on initial load,
    // so you should check your state object and handle things accordingly.
    // (I did not do that in these examples!)

    if (myHistory.length > 0) {
        var pg = myHistory.pop();
        window.history.pushState(myHistory, "<name>", "<url>");

        //Load page data for "pg".
    } else {
        //No "history" - let them exit or keep them in the app.
    }
}

The user will never be able to navigate forward using their browser buttons because they are always on the newest page.

From the browser's perspective, every time they go "back", they've immediately pushed forward again.

From the user's perspective, they're able to navigate backwards through the pages but not forward (basically simulating the smartphone "page stack" model).

From the developer's perspective, you now have a high level of control over how the user navigates through your application, while still allowing them to use the familiar navigation buttons on their browser. You can add/remove items from anywhere in the history chain as you please. If you use objects in your history array, you can track extra information about the pages as well (like field contents and whatnot).

If you need to handle user-initiated navigation (like the user changing the URL in a hash-based navigation scheme), then you might use a slightly different approach like...

var myHistory = [];

function pageLoad() {
    // When the user first hits your page...
    // Check the state to see what's going on.

    if (window.history.state === null) {
        // If the state is null, this is a NEW navigation,
        //    the user has navigated to your page directly (not using back/forward).

        // First we establish a "back" page to catch backward navigation.
        window.history.replaceState(
            { isBackPage: true },
            "<back>",
            "<back>"
        );

        // Then push an "app" page on top of that - this is where the user will sit.
        // (As browsers vary, it might be safer to put this in a short setTimeout).
        window.history.pushState(
            { isBackPage: false },
            "<name>",
            "<url>"
        );

        // We also need to start our history tracking.
        myHistory.push("<whatever>");

        return;
    }

    // If the state is NOT null, then the user is returning to our app via history navigation.

    // (Load up the page based on the last entry of myHistory here)

    if (window.history.state.isBackPage) {
        // If the user came into our app via the back page,
        //     you can either push them forward one more step or just use pushState as above.

        window.history.go(1);
        // or window.history.pushState({ isBackPage: false }, "<name>", "<url>");
    }

    setTimeout(function() {
        // Add our popstate event listener - doing it here should remove
        //     the issue of dealing with the browser firing it on initial page load.
        window.addEventListener("popstate", on_popstate);
    }, 100);
}

function on_popstate(e) {
    if (e.state === null) {
        // If there's no state at all, then the user must have navigated to a new hash.

        // <Look at what they've done, maybe by reading the hash from the URL>
        // <Change/load the new page and push it onto the myHistory stack>
        // <Alternatively, ignore their navigation attempt by NOT loading anything new or adding to myHistory>

        // Undo what they've done (as far as navigation) by kicking them backwards to the "app" page
        window.history.go(-1);

        // Optionally, you can throw another replaceState in here, e.g. if you want to change the visible URL.
        // This would also prevent them from using the "forward" button to return to the new hash.
        window.history.replaceState(
            { isBackPage: false },
            "<new name>",
            "<new url>"
        );
    } else {
        if (e.state.isBackPage) {
            // If there is state and it's the 'back' page...

            if (myHistory.length > 0) {
                // Pull/load the page from our custom history...
                var pg = myHistory.pop();
                // <load/render/whatever>

                // And push them to our "app" page again
                window.history.pushState(
                    { isBackPage: false },
                    "<name>",
                    "<url>"
                );
            } else {
                // No more history - let them exit or keep them in the app.
            }
        }

        // Implied 'else' here - if there is state and it's NOT the 'back' page
        //     then we can ignore it since we're already on the page we want.
        //     (This is the case when we push the user back with window.history.go(-1) above)

The reason why you see this error I guess is because RStudio lost the path of your working directory.

(1) Go to session...

(2) Set working directory...

(3) Choose directory...

--> Then you can see a window pops up.

--> Choose the folder where you store your data.

This is the way without any code that you change your working directory. Hope this can help you.

None of the previously given examples were meeting my needs completely, so I wrote my own queue that allows following functionality: iteration, index access, indexOf, lastIndexOf, get first, get last, offer, remaining capacity, expand capacity, dequeue last, dequeue first, enqueue / add element, dequeue / remove element, subQueueCopy, subArrayCopy, toArray, snapshot, basics like size, remove or contains.

Take care of download the right version of Phalcon:

Phalcon 1.3.2 - Windows x86 for PHP 5.5.0 (VC11)

This also happened to me but using Dynamic Features. I already had Java 8 compatibility enabled in the app module but I had to add this compatibility lines to the Dynamic Feature module and then it worked.

Here are a few general tips for you:

• You can use foreach on types that implement IEnumerable. IList is essentially an IEnumberable with Count and Item (accessing items using a zero-based index) properties. IDictionary on the other hand means you can access items by any-hashable index.

• Array, ArrayList and List all implement IList. Dictionary, SortedDictionary, and Hashtable implement IDictionary.

• If you are using .NET 2.0 or higher, it is recommended that you use generic counterparts of mentioned types.

• For time and space complexity of various operations on these types, you should consult their documentation.

• .NET data structures are in System.Collections namespace. There are type libraries such as PowerCollections which offer additional data structures.

• To get a thorough understanding of data structures, consult resources such as CLRS.

.icon{
background: url(1.jpg) no-repeat;
padding-left:25px;
}

add above tags into your CSS file and use the specified class.

(for Mac users) I have the same problem but i solved by this simple way: You have to put your chromedriver.exe in the same folder to your executed script and than in pyhton write this instruction :

import os

os.environ["PATH"] += os.pathsep + r'X:/your/folder/script/'

Edit (2017-10-12):

@MechaLynx and @Kevin-Weber note that unescape() is deprecated from non-browser environments and does not exist in TypeScript. decodeURIComponent is a drop-in replacement. For broader compatibility, use the below instead:

decodeURIComponent(JSON.parse('"http\\u00253A\\u00252F\\u00252Fexample.com"'));
> 'http://example.com'

Original answer:

unescape(JSON.parse('"http\\u00253A\\u00252F\\u00252Fexample.com"'));
> 'http://example.com'

You can offload all the work to JSON.parse

Not sure if this helps, but with XSL, I'd do something like:

<xsl:for-each select="a/b">
    <xsl:value-of select="c"/>
    <xsl:value-of select="d"/>
    <xsl:value-of select="e"/>
</xsl:for-each>

and won't this XPath select all children of B nodes:

a/b/*

First, the enum methods shouldn't be in all caps. They are methods just like other methods, with the same naming convention.

Second, what you are doing is not the best possible way to set up your enum. Instead of using an array of values for the values, you should use separate variables for each value. You can then implement the constructor like you would any other class.

Here's how you should do it with all the suggestions above:

public enum States {
    ...
    MASSACHUSETTS("Massachusetts",  "MA",   true),
    MICHIGAN     ("Michigan",       "MI",   false),
    ...; // all 50 of those

    private final String full;
    private final String abbr;
    private final boolean originalColony;

    private States(String full, String abbr, boolean originalColony) {
        this.full = full;
        this.abbr = abbr;
        this.originalColony = originalColony;
    }

    public String getFullName() {
        return full;
    }

    public String getAbbreviatedName() {
        return abbr;
    }

    public boolean isOriginalColony(){
        return originalColony;
    }
}

I think it is worth mentioning that you don't generally need to use the whole agent string, unless perhaps you find a reason where you need to tailor the website to a specific model.

You can check for iPhone, iPad and iPod in the agent string and cover all your bases.

if((navigator.userAgent.match(/iPhone/i)) || (navigator.userAgent.match(/iPod/i)) || (navigator.userAgent.match(/iPad/i))) {
    appleMobileDevice = true;
}
else {
    appleMobileDevice = false;
}

boolarr.sum(axis=1 or axis=0)

axis = 1 will output number of trues in a row and axis = 0 will count number of trues in columns so

boolarr[[true,true,true],[false,false,true]]
print(boolarr.sum(axis=1))

will be (3,1)

After I tried algirdas' solution, my Windows crashed (Win 7 Pro 64bit) so I decided to try a different solution:

1. Start Run (Win+R)
2. Type cmd /K chcp 65001

You will get mostly what you want. To start it from the taskbar or anywhere else, make a shortcut (you can name it cmd.unicode.exe or whatever you like) and change its Target to C:\Windows\System32\cmd.exe /K chcp 65001.

I don't know how good that solution is but it is definitely THE EASY ONE i just used in my app and it is working fine

you load the image like that

public void loadImage (){
Picasso picasso = Picasso.get(); 
picasso.setIndicatorsEnabled(true);
picasso.load(quiz.getImageUrl()).into(quizImage);
}

You can get the bimap like that

Bitmap bitmap = Picasso.get().load(quiz.getImageUrl()).get();

Now covert that Bitmap into a JPG file and store in the in the cache, below is complete code for getting the bimap and caching it

Thread thread = new Thread() {
 public void run() {
 File file = new File(getCacheDir() + "/" +member.getMemberId() + ".jpg");

try {
      Bitmap bitmap = Picasso.get().load(uri).get();
      FileOutputStream fOut = new FileOutputStream(file);                                        
      bitmap.compress(Bitmap.CompressFormat.JPEG, 100,new FileOutputStream(file));
fOut.flush();
fOut.close();
    }
catch (Exception e) {
  e.printStackTrace();
    }
   }
};
     thread.start();
  })

the get() method of Piccasso need to be called on separate thread , i am saving that image also on that same thread.

Once the image is saved you can get all the files like that

List<File> files = new LinkedList<>(Arrays.asList(context.getExternalCacheDir().listFiles()));

now you can find the file you are looking for like below

for(File file : files){
                if(file.getName().equals("fileyouarelookingfor" + ".jpg")){ // you need the name of the file, for example you are storing user image and the his image name is same as his id , you can call getId() on user to get the file name
                    Picasso.get() // if file found then load it
                            .load(file)
                            .into(mThumbnailImage);
                    return; // return 
                }
        // fetch it over the internet here because the file is not found
       }

You should use the options 'year', 'month', and 'date' when initializing to specify the initial date value used by fullcalendar:

$('#calendar').fullCalendar({
 year: 2012,
 month: 4,
 date: 25
});  // This will initialize for May 25th, 2012.

See the function setYMD(date,y,m,d) in the fullcalendar.js file; note that the JavaScript setMonth, setDate, and setFullYear functions are used, so your month value needs to be 0-based (Jan is 0).

UPDATE: As others have noted in the comments, the correct way now (V3 as of writing this edit) is to initialize the defaultDate property to a value that is

anything the Moment constructor accepts, including an ISO8601 date string like "2014-02-01"

as it uses Moment.js. Documentation here.

Updated example:

$('#calendar').fullCalendar({
    defaultDate: "2012-05-25"
});  // This will initialize for May 25th, 2012.

On the basis that it is easier to ask forgiveness than permission (and, importantly, that the command is safe to run) I would just try to use it and catch the error (OSError in this case - I checked for file does not exist and file is not executable and they both give OSError).

It helps if the executable has something like a --version flag that is a quick no-op.

import subprocess
myexec = "python2.8"
try:
    subprocess.call([myexec, '--version']
except OSError:
    print "%s not found on path" % myexec

This is not a general solution, but will be the easiest way for a lot of use cases - those where the code needs to look for a single well known executable which is safe to run, or at least safe to run with a given flag.

Bash is a Command Line Interface that was created over twenty-seven years ago by Brian Fox as a free software replacement for the Bourne Shell. A shell is a specific kind of Command Line Interface. Bash is "open source" which means that anyone can read the code and suggest changes. Since its beginning, it has been supported by a large community of engineers who have worked to make it an incredible tool. Bash is the default shell for Linux and Mac. For these reasons, Bash is the most used and widely distributed shell.

Windows has a different Command Line Interface, called Command Prompt. While this has many of the same features as Bash, Bash is much more popular. Because of the strength of the open source community and the tools they provide, mastering Bash is a better investment than mastering Command Prompt.

To use Bash on a Windows computer, we need to download and install a program called Git Bash. Git Bash (Is the Bash for windows) allows us to easily access Bash as well as another tool called Git, inside the Windows environment.

I use this on a daily basis to show history with files that changed:

git log --stat --pretty=short --graph

To keep it short, add an alias in your .gitconfig by doing:

git config --global alias.ls 'log --stat --pretty=short --graph'

Even though I'm somewhat late answering the question:

You can now use WebElement.isDisplayed() to check if an element is visible.

Note:

There are many reasons why an element could be invisible. Selenium tries cover most of them, but there are edge cases where it does not work as expected.

For example, isDisplayed() does return false if an element has display: none or opacity: 0, but at least in my test, it does not reliably detect if an element is covered by another due to CSS positioning.

Don't confuse, if you won't give any strWindowFeatures then it will open in a new tab.

window.open('https://play.google.com/store/apps/details?id=com.drishya');

Each compiler has its own libexec/ directory. Normally libexec directory contains small helper programs called by other programs. In this case, gcc is looking for its own 'cc1' compiler. Your machine may contains different versions of gcc, and each version should have its own 'cc1'. Normally these compilers are located on:

/usr/local/libexec/gcc/<architecture>/<compiler>/<compiler_version>/cc1

Similar path for g++. Above error means, that the current gcc version used is not able to find its own 'cc1' compiler. This normally points to a PATH issue.

Specifying a VOLUME line in a Dockerfile configures a bit of metadata on your image, but how that metadata is used is important.

First, what did these two lines do:

WORKDIR /usr/src/app
VOLUME . /usr/src/app

The WORKDIR line there creates the directory if it doesn't exist, and updates some image metadata to specify all relative paths, along with the current directory for commands like RUN will be in that location. The VOLUME line there specifies two volumes, one is the relative path ., and the other is /usr/src/app, both just happen to be the same directory. Most often the VOLUME line only contains a single directory, but it can contain multiple as you've done, or it can be a json formatted array.

You cannot specify a volume source in the Dockerfile: A common source of confusion when specifying volumes in a Dockerfile is trying to match the runtime syntax of a source and destination at image build time, this will not work. The Dockerfile can only specify the destination of the volume. It would be a trivial security exploit if someone could define the source of a volume since they could update a common image on the docker hub to mount the root directory into the container and then launch a background process inside the container as part of an entrypoint that adds logins to /etc/passwd, configures systemd to launch a bitcoin miner on next reboot, or searches the filesystem for credit cards, SSNs, and private keys to send off to a remote site.

What does the VOLUME line do? As mentioned, it sets some image metadata to say a directory inside the image is a volume. How is this metadata used? Every time you create a container from this image, docker will force that directory to be a volume. If you do not provide a volume in your run command, or compose file, the only option for docker is to create an anonymous volume. This is a local named volume with a long unique id for the name and no other indication for why it was created or what data it contains (anonymous volumes are were data goes to get lost). If you override the volume, pointing to a named or host volume, your data will go there instead.

VOLUME breaks things: You cannot disable a volume once defined in a Dockerfile. And more importantly, the RUN command in docker is implemented with temporary containers. Those temporary containers will get a temporary anonymous volume. That anonymous volume will be initialized with the contents of your image. Any writes inside the container from your RUN command will be made to that volume. When the RUN command finishes, changes to the image are saved, and changes to the anonymous volume are discarded. Because of this, I strongly recommend against defining a VOLUME inside the Dockerfile. It results in unexpected behavior for downstream users of your image that wish to extend the image with initial data in volume location.

How should you specify a volume? To specify where you want to include volumes with your image, provide a docker-compose.yml. Users can modify that to adjust the volume location to their local environment, and it captures other runtime settings like publishing ports and networking.

Someone should document this! They have. Docker includes warnings on the VOLUME usage in their documentation on the Dockerfile along with advice to specify the source at runtime:

• Changing the volume from within the Dockerfile: If any build steps change the data within the volume after it has been declared, those changes will be discarded.

...

• The host directory is declared at container run-time: The host directory (the mountpoint) is, by its nature, host-dependent. This is to preserve image portability, since a given host directory can’t be guaranteed to be available on all hosts. For this reason, you can’t mount a host directory from within the Dockerfile. The VOLUME instruction does not support specifying a host-dir parameter. You must specify the mountpoint when you create or run the container.

Here is my script to measure average time

<?php

$times = [];
$nbrOfLoops = 4;
for ($i = 0; $i < $nbrOfLoops; ++$i) {
    $start = microtime(true);
    sleep(1);
    $times[] = microtime(true) - $start;
}

echo 'Average: ' . (array_sum($times) / count($times)) . 'seconds';

If using Angulars more advanced ui-router which I'd definitely recommend then you can now simply use:

$state.reload();

Which is essentially doing the same as Dunc's answer.

Under windows:

SYSTEMTIME t;
GetLocalTime(&t);
swprintf_s(buff, L"[%02d:%02d:%02d:%d]\t", t.wHour, t.wMinute, t.wSecond, t.wMilliseconds);

Not sure exactly what all the code you posted does, but to answer the question posed in the title, you can use + as the normal string concat function as well as str().

"hello " + str(10) + " world" = "hello 10 world"

Hope that helps!

in my case i want getting timeZone of several country ,first install moment js

npm install moment --save  

then install moment-timezone.js

npm install moment-timezone --save

then i import themn in my component like this

import moment from 'moment';
import timezone from 'moment-timezone'

then because iwant getting hour and minutes and second sepratly i do like this

<Clock minutes={moment().tz('Australia/Sydney').minute()} hour={moment().tz('Australia/Sydney').hours()} second={moment().tz('Australia/Sydney').second()}/>

I see what's up with the maps in the OP:

Look at the route with the intermediate point specified: The route goes slightly backwards due to that road that isn't straight.

If their algorithm won't backtrack it won't see the shorter route.

The following method is O(n) in place with constant auxiliary memory:

def rotate(arr, shift):
  pivot = shift % len(arr)
  dst = 0
  src = pivot
  while (dst != src):
    arr[dst], arr[src] = arr[src], arr[dst]
    dst += 1
    src += 1
    if src == len(arr):
      src = pivot
    elif dst == pivot:
      pivot = src

Note that in python, this approach is horribly inefficient compared to others as it can't take advantage of native implementations of any of the pieces.

If the directory ../.foo/bar/ doesn't exist, you can't create a file there, so make sure you create the directory first.

Try something like this:

File f = new File("somedirname1/somedirname2/somefilename");
if (!f.getParentFile().exists())
    f.getParentFile().mkdirs();
if (!f.exists())
    f.createNewFile();

The magic number comes from UNIX-type systems where the first few bytes of a file held a marker indicating the file type.

This error indicates you are trying to load a non-valid file type into R. For some reason, R no longer recognizes this file as an R workspace file.

C version of @Nayfe code, generating SHA1 hash from file:

#include <stdio.h>
#include <openssl/sha.h>

static const int K_READ_BUF_SIZE = { 1024 * 16 };
unsigned char* calculateSHA1(char *filename)
{
    if (!filename) {
        return NULL;
    }

    FILE *fp = fopen(filename, "rb");
    if (fp == NULL) {
        return NULL;
    }

    unsigned char* sha1_digest = malloc(sizeof(char)*SHA_DIGEST_LENGTH);
    SHA_CTX context;

    if(!SHA1_Init(&context))
        return NULL;

    unsigned char buf[K_READ_BUF_SIZE];
    while (!feof(fp))
    {
        size_t total_read = fread(buf, 1, sizeof(buf), fp);
        if(!SHA1_Update(&context, buf, total_read))
        {
            return NULL;
        }
    }
    fclose(fp);

    if(!SHA1_Final(sha1_digest, &context))
        return NULL;

    return sha1_digest;
}

It can be used as follows:

unsigned char *sha1digest = calculateSHA1("/tmp/file1");

The res variable contains the sha1 hash.

You can print it on the screen using the following for-loop:

char *sha1hash = (char *)malloc(sizeof(char) * 41);
sha1hash[41] = '\0';
int i;
for (i = 0; i < SHA_DIGEST_LENGTH; i++)
{
    sprintf(&sha1hash[i*2], "%02x", sha1digest[i]);
}
printf("SHA1 HASH: %s\n", sha1hash);

As others have said, Dir::foreach is a good option here. However, note that Dir::foreach and Dir::entries will always include . and .. (the current and parent directories). You will generally not want to work on them, so you can use Dir::each_child or Dir::children (as suggested by ma11hew28) or do something like this:

Dir.foreach('/path/to/dir') do |filename|
  next if filename == '.' or filename == '..'
  # Do work on the remaining files & directories
end

Dir::foreach and Dir::entries (as well as Dir::each_child and Dir::children) also include hidden files & directories. Often this is what you want, but if it isn't, you need to do something to skip over them.

Alternatively, you might want to look into Dir::glob which provides simple wildcard matching:

Dir.glob('/path/to/dir/*.rb') do |rb_filename|
  # Do work on files & directories ending in .rb
end

You can't. The problem is not that your app is impatient and timing out; the problem is that an intermediate proxy is impatient and timing out. "The server, while acting as a gateway or proxy, did not receive a timely response from the upstream server specified by the URI." (http://www.w3.org/Protocols/rfc2616/rfc2616-sec10.html#sec10.5.5) It most likely indicates that the origin server is having some sort of issue, so it's not responding quickly to the forwarded request.

Possible solutions, none of which are likely to make you happy:

• Increase timeout value of the proxy (if it's under your control)
• Make your request to a different server (if there's another server with the same data)
• Make your request differently (if possible) such that you are requesting less data at a time
• Try again once the server is not having issues

To further explain Sheena's answer, I needed to have setup-tools installed as a dependency of another tool e.g. more-itertools.

Download

Click the Clone or download button and choose your method. I placed these into a dev/py/libs directory in my user home directory. It does not matter where they are saved, because they will not be installed there.

• setuptools: https://github.com/pypa/setuptools
• more-itertools: https://github.com/erikrose/more-itertools

Installing setup-tools

You will need to run the following inside the setup-tools directory.

python bootstrap.py
python setup.py install

General dependencies installation

Now you can navigate to the more-itertools direcotry and install it as normal.

1. Download the package
2. Unpackage it if it's an archive
3. Navigate (cd ...) into the directory containing setup.py
4. If there are any installation instructions contained in the documentation contained herein, read and follow the instructions OTHERWISE
5. Type in: python setup.py install

Right click on the web page you want to use as the default page and choose "Set as Start Page" whenever you run the web application from Visual Studio, it will open the selected page.

It isn't needed probably but if it is, here's some code

import os

def file_exists(path, filename):
    for file_or_folder in os.listdir(path):
        if file_or_folder == filename:
            return True
    return False

You might also be interested in https://github.com/phadej/igbinary - which provides a different serialization 'engine' for PHP.

My random/arbitrary 'performance' figures, using PHP 5.3.5 on a 64bit platform show :

JSON :

• JSON encoded in 2.180496931076 seconds
• JSON decoded in 9.8368630409241 seconds
• serialized "String" size : 13993

Native PHP :

• PHP serialized in 2.9125759601593 seconds
• PHP unserialized in 6.4348418712616 seconds
• serialized "String" size : 20769

Igbinary :

• WIN igbinary serialized in 1.6099879741669 seconds
• WIN igbinrary unserialized in 4.7737920284271 seconds
• WIN serialized "String" Size : 4467

So, it's quicker to igbinary_serialize() and igbinary_unserialize() and uses less disk space.

I used the fillArray(0, 3) code as above, but made the array keys longer strings.

igbinary can store the same data types as PHP's native serialize can (So no problem with objects etc) and you can tell PHP5.3 to use it for session handling if you so wish.

By default, CORS does not include cookies on cross-origin requests. This is different from other cross-origin techniques such as JSON-P. JSON-P always includes cookies with the request, and this behavior can lead to a class of vulnerabilities called cross-site request forgery, or CSRF.

In order to reduce the chance of CSRF vulnerabilities in CORS, CORS requires both the server and the client to acknowledge that it is ok to include cookies on requests. Doing this makes cookies an active decision, rather than something that happens passively without any control.

The client code must set the withCredentials property on the XMLHttpRequest to true in order to give permission.

However, this header alone is not enough. The server must respond with the Access-Control-Allow-Credentials header. Responding with this header to true means that the server allows cookies (or other user credentials) to be included on cross-origin requests.

You also need to make sure your browser isn't blocking third-party cookies if you want cross-origin credentialed requests to work.

Note that regardless of whether you are making same-origin or cross-origin requests, you need to protect your site from CSRF (especially if your request includes cookies).

You are inside a namespace so you should use \Exception to specify the global namespace:

try {

  $this->buildXMLHeader();

} catch (\Exception $e) {

    return $e->getMessage();
}

In your code you've used catch (Exception $e) so Exception is being searched in/as:

App\Services\PayUService\Exception

Since there is no Exception class inside App\Services\PayUService so it's not being triggered. Alternatively, you can use a use statement at the top of your class like use Exception; and then you can use catch (Exception $e).

This is what I used for my countdown clock:

</SCRIPT>
<center class="auto-style19" style="height: 31px">
<Font face="blacksmith" size="large"><strong>
<SCRIPT LANGUAGE="JavaScript">
var header = "You have <I><font color=red>" 
+ getDaysUntilICD10() + "</font></I>&nbsp; "
header += "days until ICD-10 starts!"
document.write(header)
</SCRIPT>

The HTML inside of my script worked, though I could not explain why.
