It's been a few good days with node, and you're right to say that you can't create a webserver without gzip.

There are quite a lot options given on the modules page on the Node.js Wiki. I tried out most of them, but this is the one which I'm finally using -

https://github.com/donnerjack13589/node.gzip

v1.0 is also out and it has been quite stable so far.

Here's the method I use if you can get your dupe criteria into a group by statement and your table has an id identity column for uniqueness:

delete t
from tablename t
inner join  
(
    select date_time, min(id) as min_id
    from tablename
    group by date_time
    having count(*) > 1
) t2 on t.date_time = t2.date_time
where t.id > t2.min_id

In this example the date_time is the grouping criteria, if you have more than one column make sure to join on all of them.

Use time

Let's say you have the initial dates as strings like these:
date1 = "31/12/2015"
date2 = "01/01/2016"

You can do the following:
newdate1 = time.strptime(date1, "%d/%m/%Y") and newdate2 = time.strptime(date2, "%d/%m/%Y") to convert them to python's date format. Then, the comparison is obvious:

newdate1 > newdate2 will return False
newdate1 < newdate2 will return True

In C++, unlike (say) Java, an instance of a nested class doesn't intrinsically belong to any instance of the enclosing class. So bar::getA doesn't have any specific instance of foo whose a it can be returning. I'm guessing that what you want is something like:

    class bar {
      private:
        foo * const owner;
      public:
        bar(foo & owner) : owner(&owner) { }
        int getA() {return owner->a;}
    };

But even for this you may have to make some changes, because in versions of C++ before C++11, unlike (again, say) Java, a nested class has no special access to its enclosing class, so it can't see the protected member a. This will depend on your compiler version. (Hat-tip to Ken Wayne VanderLinde for pointing out that C++11 has changed this.)

@(new HtmlString(myString))

One more variant:

export PATH=$PATH:\`pwd`:/foo/bar

You need a table variable:

declare @values table
(
    Value varchar(1000)
)

insert into @values values ('A')
insert into @values values ('B')
insert into @values values ('C')

select blah
from foo
where myField in (select value from @values)

You can use jQuery click instead of using onclick attribute, Try the following:

$('table').on('click', 'input[type="button"]', function(e){
   $(this).closest('tr').remove()
})

Demo

The closest approach I can think of is NULLIF:

SELECT 
    ISNULL(NULLIF(O.ShipName, C.CompanyName), 1),
    O.ShipName,      
    C.CompanyName,
    O.OrderId
FROM [Northwind].[dbo].[Orders] O
INNER JOIN [Northwind].[dbo].[Customers] C
ON C.CustomerId = O.CustomerId

GO

NULLIF returns the first expression if the two expressions are not equal. If the expressions are equal, NULLIF returns a null value of the type of the first expression.

So, above query will return 1 for records in which that columns are equal, the first expression otherwise.

When passing a struct to another function, it would usually be better to do as Donnell suggested above and pass it by reference instead.

A very good reason for this is that it makes things easier if you want to make changes that will be reflected when you return to the function that created the instance of it.

Here is an example of the simplest way to do this:

#include <stdio.h>

typedef struct student {
    int age;
} student;

void addStudent(student *s) {
    /* Here we can use the arrow operator (->) to dereference 
       the pointer and access any of it's members: */
    s->age = 10;
}

int main(void) {

    student aStudent = {0};     /* create an instance of the student struct */
    addStudent(&aStudent);      /* pass a pointer to the instance */

    printf("%d", aStudent.age);

    return 0;
}

In this example, the argument for the addStudent() function is a pointer to an instance of a student struct - student *s. In main(), we create an instance of the student struct and then pass a reference to it to our addStudent() function using the reference operator (&).

In the addStudent() function we can make use of the arrow operator (->) to dereference the pointer, and access any of it's members (functionally equivalent to: (*s).age).

Any changes that we make in the addStudent() function will be reflected when we return to main(), because the pointer gave us a reference to where in the memory the instance of the student struct is being stored. This is illustrated by the printf(), which will output "10" in this example.

Had you not passed a reference, you would actually be working with a copy of the struct you passed in to the function, meaning that any changes would not be reflected when you return to main - unless you implemented a way of passing the new version of the struct back to main or something along those lines!

Although pointers may seem off-putting at first, once you get your head around how they work and why they are so handy they become second nature, and you wonder how you ever coped without them!

I am using ASP.NET MVC3 with SSRS 2008 and I couldn't get @Adrian's to work 100% for me when trying to get reports from a remote server.

Finally, I found that I needed to change the Page_Load method in ViewUserControl1.ascx to look like this:

ReportViewer1.ProcessingMode = ProcessingMode.Remote;
ServerReport serverReport = ReportViewer1.ServerReport;
serverReport.ReportServerUrl = new Uri("http://<Server Name>/reportserver");
serverReport.ReportPath = "/My Folder/MyReport";
serverReport.Refresh();

I had been missing the ProcessingMode.Remote.

I have had this problem frequently with multiple concurrent goroutines.

It may or may not be a good pattern, but I define a a struct for my workers with a quit channel and field for the worker state:

type Worker struct {
    data chan struct
    quit chan bool
    stopped bool
}

Then you can have a controller call a stop function for the worker:

func (w *Worker) Stop() {
    w.quit <- true
    w.stopped = true
}

func (w *Worker) eventloop() {
    for {
        if w.Stopped {
            return
        }
        select {
            case d := <-w.data:
                //DO something
                if w.Stopped {
                    return
                }
            case <-w.quit:
                return
        }
    }
}

This gives you a pretty good way to get a clean stop on your workers without anything hanging or generating errors, which is especially good when running in a container.

Here's a function that counts number of words in an HTML code:

$(this).val()
    .replace(/((&nbsp;)|(<[^>]*>))+/g, '') // remove html spaces and tags
    .replace(/\s+/g, ' ') // merge multiple spaces into one
    .trim() // trim ending and beginning spaces (yes, this is needed)
    .match(/\s/g) // find all spaces by regex
    .length // get amount of matches

Check Permissions In KOTLIN (RunTime)

      if((ContextCompat.checkSelfPermission(this,permission_array[0]))==PackageManager.PERMI   SSION_DENIED){
        requestPermissions(permission_array,0)
      }
    }

    override fun onRequestPermissionsResult(requestCode: Int, permissions: Array<out String>, grantResults: IntArray) {
        super.onRequestPermissionsResult(requestCode, permissions, grantResults)

          if(requestCode==0 && grantResults[0]==PackageManager.PERMISSION_GRANTED){

       //Do Your Operations Here

        ---------->
         //


          }
    }

As far as I know, can't you just make it abstract?

class parent {
public:
  virtual void handle_event(int something) const = 0 {
    // boring default code
  }
};

I thought I read on www.parashift.com that you can actually implement an abstract method. Which makes sense to me personally, the only thing it does is force subclasses to implement it, no one said anything about it not being allowed to have an implementation itself.

Use substring() and give the number of characters that you want to trim from front.

String value = "Jamaica";
value = value.substring(1);

Answer: "amaica"

You can extend a class using ApplicationRunner , override the run() method and add the code there.

import org.springframework.boot.ApplicationRunner;

@Component
public class ServerInitializer implements ApplicationRunner {

    @Override
    public void run(ApplicationArguments applicationArguments) throws Exception {

        //code goes here

    }
}

    //create TreeMap instance
    TreeMap treeMap = new TreeMap();

    //add key value pairs to TreeMap
    treeMap.put("1","One");
    treeMap.put("2","Two");
    treeMap.put("3","Three");

    /*
      get Collection of values contained in TreeMap using
      Collection values()        
    */
    Collection c = treeMap.values();

    //obtain an Iterator for Collection
    Iterator itr = c.iterator();

    //iterate through TreeMap values iterator
    while(itr.hasNext())
      System.out.println(itr.next());

or:

   for (Map.Entry<K,V> entry : treeMap.entrySet()) {
        V value = entry.getValue();
        K key = entry.getKey();
   }

or:

   // Use iterator to display the keys and associated values
   System.out.println("Map Values Before: ");
   Set keys = map.keySet();
   for (Iterator i = keys.iterator(); i.hasNext();) {
     Integer key = (Integer) i.next();
     String value = (String) map.get(key);
     System.out.println(key + " = " + value);
   }

The easiest way would be to use Runtime.getRuntime.exec().

For example, to get a registry value for the default browser on Windows:

String command = "REG QUERY HKEY_CLASSES_ROOT\\http\\shell\\open\\command";
try
{
    Process process = Runtime.getRuntime().exec(command);
} catch (IOException e)
{
    e.printStackTrace();
}

Then use a Scanner to get the output of the command, if necessary.

Scanner kb = new Scanner(process.getInputStream());

Note: the \ is an escape character in a String, and must be escaped to work properly (hence the \\).

However, there is no executable called cd, because it can't be implemented in a separate process.

The one case where the current working directory matters is executing an external process (using ProcessBuilder or Runtime.exec()). In those cases you can specify the working directory to use for the newly started process explicitly.

Easiest way for your command:

System.setProperty("user.dir", "C:\\Program Files\\Flowella");

Found that solution today. Works great for me. Even rendering PDF pages to PNG images. http://www.swftools.org/gfx_tutorial.html

You have to drop it and recreate it, but you don't have to incur the cost of revalidating the data if you don't want to.

alter table t drop constraint ck ;
alter table t add constraint ck check (n < 0) enable novalidate;

The enable novalidate clause will force inserts or updates to have the constraint enforced, but won't force a full table scan against the table to verify all rows comply.

This is still a matplotlib object. Try this:

# <your code here>
locs, labels = plt.xticks()
plt.setp(labels, rotation=45)

This post has helped me a lot, and after a few iterations, this is what we use.

The idea is to post log messages and errors to HTML, for example if you need to debug JS and don't have access to the console.

You do need to change 'console.log' with 'logThis', as it is not recommended to change native functionality.

What you'll get:

• A plain and simple 'logThis' function that will display strings and objects along with current date and time for each line
• A dedicated window on top of everything else. (show it only when needed)
• Can be used inside '.catch' to see relevant errors from promises.
• No change of default console.log behavior
• Messages will appear in the console as well.

function logThis(message) {
  // if we pass an Error object, message.stack will have all the details, otherwise give us a string
  if (typeof message === 'object') {
    message = message.stack || objToString(message);
  }

  console.log(message);

  // create the message line with current time
  var today = new Date();
  var date = today.getFullYear() + '-' + (today.getMonth() + 1) + '-' + today.getDate();
  var time = today.getHours() + ':' + today.getMinutes() + ':' + today.getSeconds();
  var dateTime = date + ' ' + time + ' ';

  //insert line
  document.getElementById('logger').insertAdjacentHTML('afterbegin', dateTime + message + '<br>');
}

function objToString(obj) {
  var str = 'Object: ';
  for (var p in obj) {
    if (obj.hasOwnProperty(p)) {
      str += p + '::' + obj[p] + ',\n';
    }
  }
  return str;
}

const object1 = {
  a: 'somestring',
  b: 42,
  c: false
};

logThis(object1)
logThis('And all the roads we have to walk are winding, And all the lights that lead us there are blinding')

#logWindow {
  overflow: auto;
  position: absolute;
  width: 90%;
  height: 90%;
  top: 5%;
  left: 5%;
  right: 5%;
  bottom: 5%;
  background-color: rgba(0, 0, 0, 0.5);

}

Thanks this answer too, JSON.stringify() didn't work for this.

To give a bit more explanation, Python will automatically construct its search paths (as mentioned above and here) using the site.py script (typically located in sys.prefix + lib/python<version>/site-packages as well as lib/site-python). One can obtain the value of sys.prefix:

python -c 'import sys; print(sys.prefix)'

The site.py script then adds a number of directories, dependent upon the platform, such as /usr/{lib,share}/python<version>/dist-packages, /usr/local/lib/python<version>/dist-packages to the search path and also searches these paths for <package>.pth config files which contain specific additional search paths. For example easy-install maintains its collection of installed packages which are added to a system specific file e.g on Ubuntu it's /usr/local/lib/python2.7/dist-packages/easy-install.pth. On a typical system there are a bunch of these .pth files around which can explain some unexpected paths in sys.path:

python -c 'import sys; print(sys.path)'

So one can create a .pth file and put in any of these directories (including the sitedir as mentioned above). This seems to be the way most packages get added to the sys.path as opposed to using the PYTHONPATH.

Note: On OSX there's a special additional search path added by site.py for 'framework builds' (but seems to work for normal command line use of python): /Library/Python/<version>/site-packages (e.g. for Python2.7: /Library/Python/2.7/site-packages/) which is where 3rd party packages are supposed to be installed (see the README in that dir). So one can add a path configuration file in there containing additional search paths e.g. create a file called /Library/Python/2.7/site-packages/pip-usr-local.pth which contains /usr/local/lib/python2.7/site-packages/ and then the system python will add that search path.

There are two ways to do it: creating filter condition 1) Manually 2) Dynamically.

Sample DataFrame:

val df = spark.createDataFrame(Seq(
  (0, "a1", "b1", "c1", "d1"),
  (1, "a2", "b2", "c2", "d2"),
  (2, "a3", "b3", null, "d3"),
  (3, "a4", null, "c4", "d4"),
  (4, null, "b5", "c5", "d5")
)).toDF("id", "col1", "col2", "col3", "col4")

+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
|  0|  a1|  b1|  c1|  d1|
|  1|  a2|  b2|  c2|  d2|
|  2|  a3|  b3|null|  d3|
|  3|  a4|null|  c4|  d4|
|  4|null|  b5|  c5|  d5|
+---+----+----+----+----+

1) Creating filter condition manually i.e. using DataFrame where or filter function

df.filter(col("col1").isNotNull && col("col2").isNotNull).show

or

df.where("col1 is not null and col2 is not null").show

Result:

+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
|  0|  a1|  b1|  c1|  d1|
|  1|  a2|  b2|  c2|  d2|
|  2|  a3|  b3|null|  d3|
+---+----+----+----+----+

2) Creating filter condition dynamically: This is useful when we don't want any column to have null value and there are large number of columns, which is mostly the case.

To create the filter condition manually in these cases will waste a lot of time. In below code we are including all columns dynamically using map and reduce function on DataFrame columns:

val filterCond = df.columns.map(x=>col(x).isNotNull).reduce(_ && _)

How filterCond looks:

filterCond: org.apache.spark.sql.Column = (((((id IS NOT NULL) AND (col1 IS NOT NULL)) AND (col2 IS NOT NULL)) AND (col3 IS NOT NULL)) AND (col4 IS NOT NULL))

Filtering:

val filteredDf = df.filter(filterCond)

Result:

+---+----+----+----+----+
| id|col1|col2|col3|col4|
+---+----+----+----+----+
|  0|  a1|  b1|  c1|  d1|
|  1|  a2|  b2|  c2|  d2|
+---+----+----+----+----+

Actually you don't have to create an image at all. drawImage() will accept a Canvas as well as an Image object.

//grab the context from your destination canvas
var destCtx = destinationCanvas.getContext('2d');

//call its drawImage() function passing it the source canvas directly
destCtx.drawImage(sourceCanvas, 0, 0);

Way faster than using an ImageData object or Image element.

Note that sourceCanvas can be a HTMLImageElement, HTMLVideoElement, or a HTMLCanvasElement. As mentioned by Dave in a comment below this answer, you cannot use a canvas drawing context as your source. If you have a canvas drawing context instead of the canvas element it was created from, there is a reference to the original canvas element on the context under context.canvas.

Here is a jsPerf to demonstrate why this is the only right way to clone a canvas: http://jsperf.com/copying-a-canvas-element

There is no advantage of using one vs the other, but, there is a specific case where throw won't work. However, those cases can be fixed.

Any time you are inside of a promise callback, you can use throw. However, if you're in any other asynchronous callback, you must use reject.

For example, this won't trigger the catch:

new Promise(function() {
  setTimeout(function() {
    throw 'or nah';
    // return Promise.reject('or nah'); also won't work
  }, 1000);
}).catch(function(e) {
  console.log(e); // doesn't happen
});

Instead you're left with an unresolved promise and an uncaught exception. That is a case where you would want to instead use reject. However, you could fix this in two ways.

1. by using the original Promise's reject function inside the timeout:

new Promise(function(resolve, reject) {
  setTimeout(function() {
    reject('or nah');
  }, 1000);
}).catch(function(e) {
  console.log(e); // works!
});

2. by promisifying the timeout:

function timeout(duration) { // Thanks joews
  return new Promise(function(resolve) {
    setTimeout(resolve, duration);
  });
}

timeout(1000).then(function() {
  throw 'worky!';
  // return Promise.reject('worky'); also works
}).catch(function(e) {
  console.log(e); // 'worky!'
});

Here is an article that explains the problem and solution with alot more detail:

Sorting Locked Cells in Protected Worksheets

The thing to understand is that the purpose of locking cells is to prevent them from being changed, and sorting permanently changes cell values. You can write a macro, but a much better solution is to use the "Allow Users to Edit Ranges" feature. This makes the cells editable so sorting can work, but because the cells are still technically locked you can prevent users from selecting them.

Using -replace

l = [1, 2, 3, 4, 5]
del l[0:3] # Here 3 specifies the number of items to be deleted.

This is the code if you want to delete a number of items from the list. You might as well skip the zero before the colon. It does not have that importance. This might do as well.

l = [1, 2, 3, 4, 5]
del l[:3] # Here 3 specifies the number of items to be deleted.

I am pretty sure that those volumes are actually mounted on your system. Look in /proc/mounts and you will see them there. You will likely need to sudo umount <path> or sudo umount -f -n <path>. You should be able to get the mounted path either in /proc/mounts or through docker volume inspect

Or if you would try :

$("#foo").find("select[name=bar]").val();

I used It today and It working fine.

To sandwich an my element between the modal screen and a dialog, I need to lift my element above the modal-screen, and then lift the dialog above my element.

I had a small success by doing the following after creating the dialog on element $dlg.

$dlg.closest('.ui-dialog').css('zIndex',adjustment);

Since each dialog has a different starting z-index (they incrementally get larger) I make adjustment a string with a boost value, like this:

const adjustment = "+=99";

However, jQuery just keeps increasing the zIndex value on the modal screen, so by the second dialog, the sandwich no longer worked. I gave up on ui-dialog "modal", made it "false", and just created my own modal. It imitates jQueryUI exactly. Here it is:

CoverAll = {};
CoverAll.modalDiv = null;

CoverAll.modalCloak = function(zIndex) {

Add something to track the length and allow you to do "checks" on whether the user is adding or subtracting text. This is currently untested but something similar to this should work (especially if you have a userform).

'add this to your userform or make it a static variable if it is not part of a userform
private oldLength as integer

Private Sub txtBoxBDayHim_Change()
    if ( oldlength > txboxbdayhim.textlength ) then
        oldlength =txtBoxBDayHim.textlength
        exit sub
    end if

    If txtBoxBDayHim.TextLength = 2 or txtBoxBDayHim.TextLength = 5 then
    txtBoxBDayHim.Text = txtBoxBDayHim.Text + "/"
    end if
    oldlength =txtBoxBDayHim.textlength
End Sub

The easiest option for me was to rename the title of the terminal instead. Please see: https://superuser.com/questions/362227/how-to-change-the-title-of-the-mintty-window

In this answer, they mention to modify the PS1 variable. Note: my situation was particular to cygwin.

TL;DR Put this in your .bashrc file:

function settitle() {
      export PS1="\[\e[32m\]\u@\h \[\e[33m\]\w\[\e[0m\]\n$ "
      echo -ne "\e]0;$1\a"
}

Put this in your .tmux.conf file, or similar formatting:

set -g pane-border-status bottom
set -g pane-border-format "#P #T #{pane_current_command}"

Then you can change the title of the pane by typing this in the console:

settitle titlename

I had to combine COMPOSER_MEMORY_LIMIT and memory_limit in the command line:

On Windows:

set COMPOSER_MEMORY_LIMIT=99999999999&& php -d memory_limit=-1 composer.phar update

On Linux:

export COMPOSER_MEMORY_LIMIT=99999999999 && php -d memory_limit=-1 composer.phar update

There is often the tip to use 'echo.'

But that is slow, and it could fail with an error message, as cmd.exe will search first for a file named 'echo' (without extension) and only when the file doesn't exists it outputs an empty line.

You could use echo(. This is approximately 20 times faster, and it works always. The only drawback could be that it looks odd.

More about the different ECHO:/\ variants is at DOS tips: ECHO. FAILS to give text or blank line.

Maybe something like this:

import matplotlib.pyplot
import pylab

x = [1,2,3,4]
y = [3,4,8,6]

matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

EDIT:

Let me see if I understand you correctly now:

You have:

       test1 | test2 | test3
test3 |   1   |   0  |  1

test4 |   0   |   1  |  0

test5 |   1   |   1  |  0

Now you want to represent the above values in in a scatter plot, such that value of 1 is represented by a dot.

Let's say you results are stored in a 2-D list:

results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

We want to transform them into two variables so we are able to plot them.

And I believe this code will give you what you are looking for:

import matplotlib
import pylab


results = [[1, 0, 1], [0, 1, 0], [1, 1, 0]]

x = []
y = []

for ind_1, sublist in enumerate(results):
    for ind_2, ele in enumerate(sublist):
        if ele == 1:
            x.append(ind_1)
            y.append(ind_2)       


matplotlib.pyplot.scatter(x,y)

matplotlib.pyplot.show()

Notice that I do need to import pylab, and you would have play around with the axis labels. Also this feels like a work around, and there might be (probably is) a direct method to do this.

I was able to import the module within the function (only) that would require the objects from this module:

def my_func():
    import Foo
    foo_instance = Foo()

Whatever your separator is in your ls.dat, you can specify it to gnuplot:

set datafile separator "\t"

For me it was because I hadn't set an active class on any of the slides.

.gc is a candidate for elimination in future releases - a Sun Engineer once commented that maybe fewer than twenty people in the world actually know how to use .gc() - I did some work last night for a few hours on a central / critical data-structure using SecureRandom generated data, at somewhere just past 40,000 objects the vm would slow down as though it had run out of pointers. Clearly it was choking down on 16-bit pointer tables and exhibited classic "failing machinery" behavior.

I tried -Xms and so on, kept bit twiddling until it would run to about 57,xxx something. Then it would run gc going from say 57,127 to 57,128 after a gc() - at about the pace of code-bloat at camp Easy Money.

Your design needs fundamental re-work, probably a sliding window approach.

Taking this one step further, to save a file to a relative directory, you can use the replace function. Say you have your workbook saved in: c:\property\california\sacramento\workbook.xlsx, use this to move the property to berkley:

workBookPath = Replace(ActiveWorkBook.path, "sacramento", "berkley")
myWorkbook.SaveAs(workBookPath & "\" & "newFileName.xlsx"

Only works if your file structure contains one instance of the text used to replace. YMMV.

If you have readonly attribute, blur by itself would not work. Contraption below should do the job.

$('#myInputID').removeAttr('readonly').trigger('blur').attr('readonly','readonly');

I had a differnt problem on Windows 10 with Visual Studio 2017 but with the same effects. I think my problems came down to VS being installed onto a drive other than "C:\". I solved the problem by Reinstalling Windows 10 SDK

First I had to uninstall the Windows SDK (there were two versions installed). Then ran the executable. Once installed, ran visual studio and it worked fine.

i no expert, but this works for me..

$sql = "desc MyTable";
$result = @mysql_query($sql);
while($row = @mysql_fetch_array($result)){
    echo $row[0]."<br>"; // returns the first column of array. in this case Field

      // the below code will return a full array-> Field,Type,Null,Key,Default,Extra    
      // for ($c=0;$c<sizeof($row);$c++){echo @$row[$c]."<br>";}    

}

Bill, I dare answer your question, however I am not 100% sure with my guesses. I think other then IE browsers when taking user to a page in history will not only load the page and its resources from cache but they will also restore the entire DOM (read session) state for it. IE doesn't do DOM restoration (or at lease did not do) and thus the onload event looks to be necessary for proper page re-initialization there.

setRetainInstance(boolean) is useful when you want to have some component which is not tied to Activity lifecycle. This technique is used for example by rxloader to "handle Android's activity lifecyle for rxjava's Observable" (which I've found here).

Here is an extension method:

public static decimal? TruncateDecimalPlaces(this decimal? value, int places)
    {
        if (value == null)
        {
            return null;
        }

        return Math.Floor((decimal)value * (decimal)Math.Pow(10, places)) / (decimal)Math.Pow(10, places);

    } // end

Follow the instructions here, it solved my problem.

you have to run the command like as follow; patch -p0 --dry-run < path/to/your/patchFile/yourPatch.patch

An alternative setting is to have the default virtual host at the end of the config file rather than the beginning. This way, all alternative virtual hosts will be checked before being matched by the default virtual host.

Example:

NameVirtualHost *:80
Listen 80

...

<VirtualHost *:80>
        ServerName host1
        DocumentRoot /someDir
</VirtualHost>

<VirtualHost *:80>
        ServerName host2
        DocumentRoot /someOtherDir
</VirtualHost>

<VirtualHost *:80>
        DocumentRoot /defaultDir
</VirtualHost>

Using a HTTP debugging proxy can cause this - such as Fiddler.

I was loading a PFX certificate from a local file (authentication to Apple.com) and it failed because Fiddler wasn't able to pass this certificate on.

Try disabling Fiddler to check and if that is the solution then you need to probably install the certificate on your machine or in some way that Fiddler can use it.

Removing the name from your binding will make it apply to all endpoints, and should produce the desired results. As so:

<services>
  <service name="Service.IService">
    <clear />
    <endpoint binding="basicHttpBinding" contract="Service.IService" />
  </service>
</services>
<bindings>
  <basicHttpBinding>
    <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647">
      <readerQuotas maxDepth="32" maxStringContentLength="2147483647"
        maxArrayLength="16348" maxBytesPerRead="4096" maxNameTableCharCount="16384" />
    </binding>
  </basicHttpBinding>
  <webHttpBinding>
    <binding maxBufferSize="2147483647" maxReceivedMessageSize="2147483647" />
  </webHttpBinding>
</bindings>

Also note that I removed the bindingConfiguration attribute from the endpoint node. Otherwise you would get an exception.

React Native Dimensions is only a partial answer to this question, I came here looking for the actual pixel size of the screen, and the Dimensions actually gives you density independent layout size.

You can use React Native Pixel Ratio to get the actual pixel size of the screen.

You need the import statement for both Dimenions and PixelRatio

import { Dimensions, PixelRatio } from 'react-native';

You can use object destructuring to create width and height globals or put it in stylesheets as others suggest, but beware this won't update on device reorientation.

const { width, height } = Dimensions.get('window');

From React Native Dimension Docs:

Note: Although dimensions are available immediately, they may change (e.g due to >device rotation) so any rendering logic or styles that depend on these constants >should try to call this function on every render, rather than caching the value >(for example, using inline styles rather than setting a value in a StyleSheet).

PixelRatio Docs link for those who are curious, but not much more there.

To actually get the screen size use:

PixelRatio.getPixelSizeForLayoutSize(width);

or if you don't want width and height to be globals you can use it anywhere like this

PixelRatio.getPixelSizeForLayoutSize(Dimensions.get('window').width);

I had the same question but figured it out finally. What you most likely need to do is run the following two git commands (replacing hash with the git commit revision number):

git checkout <hash>
git push -f HEAD:master

increase the padding size of font and then try to increase font size:-

style="padding-bottom:40px; font-size: 50px;"

Look at the static System.Drawing.Printing.PrinterSettings.InstalledPrinters property.

It is a list of the names of all installed printers on the system.

If you're looking to access the current page from within your functions.php file (so, before the loop, before $post is populated, before $wp_query is initialized, etc...) you really have no choice but to access the server variables themselves and extract the requested page from the query string.

$page_slug = trim( $_SERVER["REQUEST_URI"] , '/' )

Note that this is a "dumb" solution. It doesn't know, for instance that the page with the slug 'coming-soon' is also p=6. And it assumes that your permalink settings are set to pagename (which they should be anyway!).

Still, can be a useful little trick if you have a controlled scenario. I'm using this in a situation where I wish to redirect non-logged in visitors to a "coming soon" page; but I have to make sure that I'm not throwing them into the dreaded "redirect loop", so I need to exclude the "coming soon" page from this rule:

global $pagenow;
if (
        ! is_admin() &&
        'wp-login.php' != $pagenow &&
        'coming-soon' != trim( $_SERVER["REQUEST_URI"] , '/' ) &&
        ! is_user_logged_in()
){
   wp_safe_redirect( 'coming-soon' );
}

I assume one uses print_r for debugging. I would then suggest using libraries like Kint. This allows displaying big arrays in a readable format:

$data = [['Natural Child 1', 'Natural Child 2', 'Natural Child 3']];
Kint::dump($data, $_SERVER);

If you are using the new** Gradle build system then getPackageName will oddly return application Id, not package name. So MasterGaurav's answer is correct but he doesn't need to start off with ++

If by application id, you're referring to package name...

See more about the differences here.

** not so new at this point

++ I realize that his answer made perfect sense in 2011

This can occur because of you are trying to checking out the repository by accessing it via a proxy server without enabling the proxy server in the place you need to change the settings in TortoiseSvn. So if you are using a proxy server make sure that you put a tick in "Enable Proxy Server" in Settings->Network and give your Server address and Port number in the relevant places. Now try to check out again.

UPDATE 2: This information is no more given by facebook. There is an official announcement for the behavior change (https://developers.facebook.com/blog/post/2018/04/19/facebook-login-changes-address-abuse/) but none for its alternative.

Yes, Just use this link and append your ID to the id parameter:

https://facebook.com/profile.php?id=<UID>

So for example:

https://facebook.com/profile.php?id=4

Will redirect you automatically to https://www.facebook.com/zuck Which is Mark Zuckerberg's profile.

If you want to do this for all your ids, then you can do it using a loop.

If you'd like, I can provide you with a snippet.

UPDATE: Alternatively, You can also do this:

https://facebook.com/<UID>

So that would be: https://facebook.com/4 which would automatically redirect to Zuck!

Just also to draw your attention to this:

https://code.msdn.microsoft.com/windowsdesktop/C-and-Python-interprocess-171378ee

It works great.

In Django 3.0 auto_now_add seems to work with auto_now

reg_date=models.DateField(auto_now=True,blank=True)

You should return the line that redirects

return res.redirect('/UserHomePage');

While most of these answers are correct to varying degrees, none of them are as succinct as I would like.

Put simply, using while True: is just a way of running a loop that will continue to run until you explicitly break out of it using break or return. Since True will always evaluate to True, you have to force the loop to end when you want it to.

while True:
    # do stuff

    if some_condition:
        break

    # do more stuff - code here WILL NOT execute when `if some_condition:` evaluates to True

While normally a loop would be set to run until the while condition is false, or it reaches a predefined end point:

do_next = True

while do_next:

    # do stuff

    if some_condition:
        do_next = False

    # do more stuff - code here WILL execute even when `if some_condition:` evaluates to True

Those two code chunks effectively do the same thing

If the condition your loop evaluates against is possibly a value not directly in your control, such as a user input value, then validating the data and explicitly breaking out of the loop is usually necessary, so you'd want to do it with either method.

The while True format is more pythonic since you know that break is breaking the loop at that exact point, whereas do_next = False could do more stuff before the next evaluation of do_next.

As others have pointed out, you only need to close the outer wrapper.

BufferedReader reader = new BufferedReader(new FileReader(fileName));

There is a very slim chance that this could leak a file handle if the BufferedReader constructor threw an exception (e.g. OutOfMemoryError). If your app is in this state, how careful your clean up needs to be might depend on how critical it is that you don't deprive the OS of resources it might want to allocate to other programs.

The Closeable interface can be used if a wrapper constructor is likely to fail in Java 5 or 6:

Reader reader = new FileReader(fileName);
Closeable resource = reader;
try {
  BufferedReader buffered = new BufferedReader(reader);
  resource = buffered;
  // TODO: input
} finally {
  resource.close();
}

Java 7 code should use the try-with-resources pattern:

try (Reader reader = new FileReader(fileName);
    BufferedReader buffered = new BufferedReader(reader)) {
  // TODO: input
}

You must create your own Pipe for array sorting, here is one example how can you do that.

<li *ngFor="#item of array | arraySort:'-date'">{{item.name}} {{item.date | date:'medium' }}</li>

https://plnkr.co/edit/DU6pxr?p=preview

It is valid.

However, standard practice is to use href="#" or sometimes href="javascript:;".

For me, this is the best way.

var arrayOfNums = [1,4,5,68,9,10]

for i in 0..<arrayOfNums.count {
    print(arrayOfNums[arrayOfNums.count - i - 1])
}

You can get the different values with:

set(Article.objects.values_list('comment_id', flat=True))

 using System.Linq; //SequenceEqual

 byte[] ByteArray1 = null;
 byte[] ByteArray2 = null;

 ByteArray1 = MyFunct1();
 ByteArray2 = MyFunct2();

 if (ByteArray1.SequenceEqual<byte>(ByteArray2) == true)
 {
    MessageBox.Show("Match");
 }
 else
 {
   MessageBox.Show("Don't match");
 }

using $(this) improves performance, as the class/whatever attr u are using to search, need not be searched for multiple times in the entire webpage content.

Here is an example `

$(document).ready(function() {
        var lastItem = null;
        $(".our-work-group > p > a").click(function(e) {
            e.preventDefault();

            var item = $(this).html(); //Here value of "this" is ".our-work-group > p > a"
            if (item == lastItem) {
                lastItem = null;
                $('.our-work-single-page').show();
            } else {
                lastItem = item;
                $('.our-work-single-page').each(function() {
                    var imgAlt = $(this).find('img').attr('alt'); //Here value of "this" is '.our-work-single-page'. 
                    if (imgAlt != item) {
                        $(this).hide();
                    } else {
                        $(this).show();
                    }
                });
            }

        });
    });`

So you can see that value of this is two different values depending on the DOM element you target but when you add "that" to the code above you change the value of "this" you are targeting.

`$(document).ready(function() {
        var lastItem = null;
        $(".our-work-group > p > a").click(function(e) {
            e.preventDefault();
            var item = $(this).html(); //Here value of "this" is ".our-work-group > p > a"
            if (item == lastItem) {
                lastItem = null;
                var that = this;
                $('.our-work-single-page').show();
            } else {
                lastItem = item;
                $('.our-work-single-page').each(function() {
                   ***$(that).css("background-color", "#ffe700");*** //Here value of "that" is ".our-work-group > p > a"....
                    var imgAlt = $(this).find('img').attr('alt'); 
                    if (imgAlt != item) {
                        $(this).hide();
                    } else {
                        $(this).show();
                    }
                });
            }

        });
    });`

.....$(that).css("background-color", "#ffe700"); //Here value of "that" is ".our-work-group > p > a" because the value of var that = this; so even though we are at "this"= '.our-work-single-page', still we can use "that" to manipulate previous DOM element.

If you already have a JavaScript function called showImage defined to show the image, you can link as such:

<a href="javascript:showImage()">show image</a>

If you need help defining the function, I would try:

function showImage() {
    var img = document.getElementById('myImageId');
    img.style.visibility = 'visible';
}

Or, better yet,

function setImageVisible(id, visible) {
    var img = document.getElementById(id);
    img.style.visibility = (visible ? 'visible' : 'hidden');
}

Then, your links would be:

<a href="javascript:setImageVisible('myImageId', true)">show image</a>
<a href="javascript:setImageVisible('myImageId', false)">hide image</a>

Put those properties files in src/test/resources. Files in src/test/resources are available within Eclipse automatically via eclipse:eclipse but will not be included in the packaged JAR by Maven.

There seems to be a new solution at the horizon. It's called EmailJS. They claim that no server code is needed. You can request an invitation.

Update August 2016: EmailJS seems to be live already. You can send up to 200 emails per month for free and it offers subscriptions for higher volumes.

new member so unfortunately im unable to comment or vote up, however Stephen Daye's post above was the perfect solution to the exact same problem that i've been looking for help with.

a small alteration to the following line:

isGPSFix = (SystemClock.elapsedRealtime() - mLastLocationMillis) < 3000;

to:

isGPSFix = (SystemClock.elapsedRealtime() - mLastLocationMillis) < (GPS_UPDATE_INTERVAL * 2);

basically as im building a slow paced game and my update interval is already set to 5 seconds, once the gps signal is out for 10+ seconds, thats the right time to trigger off something.

cheers mate, spent about 10 hours trying to solve this solution before i found your post :)

Starting with Python 3.4, one can use the glob() method of one of the Path classes in the new pathlib module, which supports ** wildcards. For example:

from pathlib import Path

for file_path in Path('src').glob('**/*.c'):
    print(file_path) # do whatever you need with these files

Update: Starting with Python 3.5, the same syntax is also supported by glob.glob().

I made some big lists. One is a list and one is a numpy array.

import numpy as np
import random
arrayv=np.random.randint(0,10,(100000000,1))
listv=[]
for i in range(0,100000000):
    listv.append(random.randint(0,9))

Using jupyter notebook's %%time function I can compare the speed of various things.

2 seconds:

%%time
listv.index(max(listv))

54.6 seconds:

%%time
listv.index(max(arrayv))

6.71 seconds:

%%time
np.argmax(listv)

103 ms:

%%time
np.argmax(arrayv)

numpy's arrays are crazy fast.

Implode will combine an array into a string for you, but to make an SQL query out a kay/value pair you'll have to write your own function.

For namespace and Library

@using NameSpace_Name

For Model

@model Application_Name.Models.Model_Name 

For Iterate the list on Razor Page (You Have to use foreach loop for access the list items)

            0, 0, 0, 0, 0,
            false, false, false, false,
            0, null);
        cancelled = !link.dispatchEvent(event);
    }
    else if (link.fireEvent) {
        cancelled = !link.fireEvent("onclick");
    }

    if (!cancelled) {
        window.location = link.href;
    }
}

I think double quotes works too:

SELECT "Business Name","Other Name" FROM your_Table

But I only tested on SQL Server NOT mySQL in case someone work with MS SQL Server.

Tracking it down

At first I thought this was a coercion bug where null was getting coerced to "null" and a test of "null" == null was passing. It's not. I was close, but so very, very wrong. Sorry about that!

I've since done lots of fiddling on wonderfl.net and tracing through the code in mx.rpc.xml.*. At line 1795 of XMLEncoder (in the 3.5 source), in setValue, all of the XMLEncoding boils down to

currentChild.appendChild(xmlSpecialCharsFilter(Object(value)));

which is essentially the same as:

currentChild.appendChild("null");

This code, according to my original fiddle, returns an empty XML element. But why?

Cause

According to commenter Justin Mclean on bug report FLEX-33664, the following is the culprit (see last two tests in my fiddle which verify this):

var thisIsNotNull:XML = <root>null</root>;
if(thisIsNotNull == null){
    // always branches here, as (thisIsNotNull == null) strangely returns true
    // despite the fact that thisIsNotNull is a valid instance of type XML
}

When currentChild.appendChild is passed the string "null", it first converts it to a root XML element with text null, and then tests that element against the null literal. This is a weak equality test, so either the XML containing null is coerced to the null type, or the null type is coerced to a root xml element containing the string "null", and the test passes where it arguably should fail. One fix might be to always use strict equality tests when checking XML (or anything, really) for "nullness."

Solution

CDATA values are the most appropriate way to mutate an entire text value that would otherwise cause encoding/decoding problems. Hex encoding, for instance, is meant for individual characters. CDATA values are preferred when you're escaping the entire text of an element. The biggest reason for this is that it maintains human readability.

    public class Main {

    public static List<String> list = new ArrayList();

    public static void main(String[] args) {

        List<Integer> l = new ArrayList<>();

        l.add(222);
        l.add(100);
        l.add(45);
        l.add(415);
        l.add(311);

        l.sort(null);
        System.out.println(l.get(0));
    }
}

without l.sort(null) returned 222

with l.sort(null) returned 45

That is because the words are wrapping and are going on new lines hence stretching the TR. This should fix your problem:

overflow:hidden;

Put that in the TR styles Although it should work, why not just let it stretch o0

PS. i aint tested it so dont hate XD

Use:

docker inspect -f "{{.Path}} {{.Args}} ({{.Id}})" $(docker ps -a -q)

That will display the command path and arguments, similar to docker ps.

Piping something into an expression involving an assignment doesn't behave like that.

Instead, try:

test=$(echo "hello world"); echo test=$test

In SQL server 2005 new datatypes were introduced: varchar(max) and nvarchar(max) They have the advantages of the old text type: they can contain op to 2GB of data, but they also have most of the advantages of varchar and nvarchar. Among these advantages are the ability to use string manipulation functions such as substring().

Also, varchar(max) is stored in the table's (disk/memory) space while the size is below 8Kb. Only when you place more data in the field, it's is stored out of the table's space. Data stored in the table's space is (usually) retrieved quicker.

In short, never use Text, as there is a better alternative: (n)varchar(max). And only use varchar(max) when a regular varchar is not big enough, ie if you expect teh string that you're going to store will exceed 8000 characters.

As was noted, you can use SUBSTRING on the TEXT datatype,but only as long the TEXT fields contains less than 8000 characters.

- (NSString *)removeWhitespaces {
  return [[self componentsSeparatedByCharactersInSet:
                    [NSCharacterSet whitespaceCharacterSet]]
      componentsJoinedByString:@""];
}

I had this problem! I tried: git fetch + git merge, but dont resolved! I tried: git pull, and also dont resolved

Then I tried this and resolved my problem (is similar of answer of Engineer):

git fetch origin master:tmp
git rebase tmp
git push origin HEAD:master
git branch -D tmp

I found this to be the easiest one. Create a new provider and user the '*' wildcard to attach it to all views. Works in 5.3 as well :-)

<?php

namespace App\Providers;

use Illuminate\Http\Request;
use Illuminate\Support\ServiceProvider;

class ViewServiceProvider extends ServiceProvider
{
    /**
     * Bootstrap the application services.
     * @return void
     */
    public function boot()
    {
        view()->composer('*', function ($view)
        {
            $user = request()->user();

            $view->with('user', $user);
        });
    }

    /**
     * Register the application services.
     *
     * @return void
     */
    public function register()
    {
        //
    }
}

I found a faster way of embedding:

• Just copy the link.
• Paste the link and remove the "?s=19" part and add "/video/1"
• That's it.

There are 2 main kinds of transactions; connection transactions and ambient transactions. A connection transaction (such as SqlTransaction) is tied directly to the db connection (such as SqlConnection), which means that you have to keep passing the connection around - OK in some cases, but doesn't allow "create/use/release" usage, and doesn't allow cross-db work. An example (formatted for space):

using (IDbTransaction tran = conn.BeginTransaction()) {
    try {
        // your code
        tran.Commit();
    }  catch {
        tran.Rollback();
        throw;
    }
}

Not too messy, but limited to our connection "conn". If we want to call out to different methods, we now need to pass "conn" around.

The alternative is an ambient transaction; new in .NET 2.0, the TransactionScope object (System.Transactions.dll) allows use over a range of operations (suitable providers will automatically enlist in the ambient transaction). This makes it easy to retro-fit into existing (non-transactional) code, and to talk to multiple providers (although DTC will get involved if you talk to more than one).

For example:

using(TransactionScope tran = new TransactionScope()) {
    CallAMethodThatDoesSomeWork();
    CallAMethodThatDoesSomeMoreWork();
    tran.Complete();
}

Note here that the two methods can handle their own connections (open/use/close/dispose), yet they will silently become part of the ambient transaction without us having to pass anything in.

If your code errors, Dispose() will be called without Complete(), so it will be rolled back. The expected nesting etc is supported, although you can't roll-back an inner transaction yet complete the outer transaction: if anybody is unhappy, the transaction is aborted.

The other advantage of TransactionScope is that it isn't tied just to databases; any transaction-aware provider can use it. WCF, for example. Or there are even some TransactionScope-compatible object models around (i.e. .NET classes with rollback capability - perhaps easier than a memento, although I've never used this approach myself).

All in all, a very, very useful object.

Some caveats:

• On SQL Server 2000, a TransactionScope will go to DTC immediately; this is fixed in SQL Server 2005 and above, it can use the LTM (much less overhead) until you talk to 2 sources etc, when it is elevated to DTC.
• There is a glitch that means you might need to tweak your connection string

Not sure why do you need w,h. If these values are actually required and mean that only specified number of rows and cols should be read than you can try the following:

output = []
with open(r'c:\file.txt', 'r') as f:
    w, h  = map(int, f.readline().split())
    tmp = []
    for i, line in enumerate(f):
        if i == h:
            break
        tmp.append(map(int, line.split()[:w]))
    output.append(tmp)

Is there some kind of query language ...

jq defines a JSON query language that is very similar to JSONPath -- see https://github.com/stedolan/jq/wiki/For-JSONPath-users

... [which] I can used to find an item in [0].objects where id = 3?

I'll assume this means: find all JSON objects under the specified key with id == 3, no matter where the object may be. A corresponding jq query would be:

.[0].objects | .. | objects | select(.id==3)

where "|" is the pipe-operator (as in command shell pipes), and where the segment ".. | objects" corresponds to "no matter where the object may be".

The basics of jq are largely obvious or intuitive or at least quite simple, and most of the rest is easy to pick up if you're at all familiar with command-shell pipes. The jq FAQ has pointers to tutorials and the like.

jq is also like SQL in that it supports CRUD operations, though the jq processor never overwrites its input. jq can also handle streams of JSON entities.

Two other criteria you might wish to consider in assessing a JSON-oriented query language are:

• does it support regular expressions? (jq 1.5 has comprehensive support for PCRE regex)
• is it Turing-complete? (yep)

Instead of setting a fixed path try this in your post-build command-line first:

SET VCTargetsPath=$(VCTargetsPath)

The variable '$(VCTargetsPath)' seems to be a c++-related visual-studio-macro which is not shown in c#-sdk-projects as a macro but is still available there.

anon, run: ./prog looks a bit strange, as right part should be a target, so run: prog looks better.

I would suggest simply:

.PHONY: run

run:
        prog $(arg1)

and I would like to add, that arguments can be passed:

1. as argument: make arg1="asdf" run
2. or be defined as environment: arg1="asdf" make run

2 ways to enable TLSv1.1 and TLSv1.2:

1. use this guideline: http://blog.dev-area.net/2015/08/13/android-4-1-enable-tls-1-1-and-tls-1-2/
2. use this class https://github.com/erickok/transdroid/blob/master/app/src/main/java/org/transdroid/daemon/util/TlsSniSocketFactory.java
   schemeRegistry.register(new Scheme("https", new TlsSniSocketFactory(), port));

you can use @see to do that:

sample:

interface View {
        /**
         * @return true: have read contact and call log permissions, else otherwise
         * @see #requestReadContactAndCallLogPermissions()
         */
        boolean haveReadContactAndCallLogPermissions();

        /**
         * if not have permissions, request to user for allow
         * @see #haveReadContactAndCallLogPermissions()
         */
        void requestReadContactAndCallLogPermissions();
    }

From MSDN:

Top-level types, which are not nested in other types, can only have internal or public accessibility. The default accessibility for these types is internal.

^{Source: Accessibility Levels (C# Reference) (December 6th, 2017)}

I don't think converting to a tuple is the right answer. You need go and look at where you are calling the function and make sure that c is a list of list of strings, or whatever you designed this function to work with

For example you might get this error if you passed [c] to the function instead of c

You can use Func<T, TResult> generic delegate. (See MSDN)

Func<MyType, ReturnType> func = (db) => { return new MyType(); }

Also there are useful generic delegates which considers a return value:

• Converter<TInput, TOutput> (MSDN)
• Predicate<TInput> - always return bool (MSDN)

Method:

public MyType SimpleUsing.DoUsing<MyType>(Func<TInput, MyType> myTypeFactory)

Generic delegate:

Func<InputArgumentType, MyType> createInstance = db => return new MyType();

Execute:

MyType myTypeInstance = SimpleUsing.DoUsing(
                            createInstance(new InputArgumentType()));

OR explicitly:

MyType myTypeInstance = SimpleUsing.DoUsing(db => return new MyType());

Use the debug lib.

import debug from 'debug'
const log = debug('server');

Use it:

log('holi')

then run:

DEBUG=server npm test

And that's it!

That DateTime format is actually ISO 8601 DateTime. JSON does not specify any particular format for dates/times. If you Google a bit, you will find plenty of implementations to parse it in Java.

Here's one

If you are open to using something other than Java's built-in Date/Time/Calendar classes, I would also suggest Joda Time. They offer (among many things) a ISODateTimeFormat to parse these kinds of strings.

This should work

The pwd command line echoes the location of the script as the current working directory no matter where I run it from.

CLOCK_REALTIME represents the machine's best-guess as to the current wall-clock, time-of-day time. As Ignacio and MarkR say, this means that CLOCK_REALTIME can jump forwards and backwards as the system time-of-day clock is changed, including by NTP.

CLOCK_MONOTONIC represents the absolute elapsed wall-clock time since some arbitrary, fixed point in the past. It isn't affected by changes in the system time-of-day clock.

If you want to compute the elapsed time between two events observed on the one machine without an intervening reboot, CLOCK_MONOTONIC is the best option.

Note that on Linux, CLOCK_MONOTONIC does not measure time spent in suspend, although by the POSIX definition it should. You can use the Linux-specific CLOCK_BOOTTIME for a monotonic clock that keeps running during suspend.

Super key is the combination of fields by which the row is uniquely identified and the candidate key is the minimal super key.

you can use ClearContents. ex,

Range("X").Cells.ClearContents

C++11 added alias declarations, which are generalization of typedef, allowing templates:

template <size_t N>
using Vector = Matrix<N, 1>;

The type Vector<3> is equivalent to Matrix<3, 1>.

In C++03, the closest approximation was:

template <size_t N>
struct Vector
{
    typedef Matrix<N, 1> type;
};

Here, the type Vector<3>::type is equivalent to Matrix<3, 1>.

Ignoring the fact that base is a reserved word you cannot do inheritance of enum.

The best thing you could do is something like that:

public enum Baseenum
{
   x, y, z
}

public enum Consume
{
   x = Baseenum.x,
   y = Baseenum.y,
   z = Baseenum.z
}

public void Test()
{
   Baseenum a = Baseenum.x;
   Consume newA = (Consume) a;

   if ((Int32) a == (Int32) newA)
   {
   MessageBox.Show(newA.ToString());
   }
}

Since they're all the same base type (ie: int) you could assign the value from an instance of one type to the other which a cast. Not ideal but it work.

I've been trying to find answer to this questions for two days. Many answers direct you to different issues. But serpentr's answer above is really to the point. It is the shortest, simplest solution. Just a reminder the last word "var" represents the variable name, so should be used as:

 result = driver.execute_script('var text = document.title ; return text')

for k, v := range m { 
    fmt.Printf("key[%s] value[%s]\n", k, v)
}

or

for k := range m {
    fmt.Printf("key[%s] value[%s]\n", k, m[k])
}

Go language specs for for statements specifies that the first value is the key, the second variable is the value, but doesn't have to be present.

You don't want to take care of normalizing your data in a view - what if the user changes the data that gets submitted? Instead you could take care of it in the model using the before_save (or the before_validation) callback. Here's an example of the relevant code for a model like yours:

class Place < ActiveRecord::Base   before_save do |place|     place.city = place.city.downcase.titleize     place.country = place.country.downcase.titleize   end end 

You can also check out the Ruby on Rails guide for more info.

To answer you question more directly, something like this would work:

<%= f.text_field :city, :value => (f.object.city ? f.object.city.titlecase : '') %>   

This just means if f.object.city exists, display the titlecase version of it, and if it doesn't display a blank string.

[updating in response to more details in the edited question]

The problem you're running into is that, once a page is modified by ajax requests, the current HTML exists only inside the browser's DOM-- there's no longer any independent source HTML that you can validate other than what you can pull out of the DOM.

As you've observed, IE's DOM stores tags in upper case, fixes up unclosed tags, and makes lots of other alterations to the HTML it got originally. This is because browsers are generally very good at taking HTML with problems (e.g. unclosed tags) and fixing up those problems to display something useful to the user. Once the HTML has been canonicalized by IE, the original source HTML is essentially lost from the DOM's perspective, as far as I know.

Firefox most likley makes fewer of these changes, so Firebug is probably your better bet.

A final (and more labor-intensive) option may work for pages with simple ajax alterations, e.g. fetching some HTML from the server and importing this into the page inside a particular element. In that case, you can use fiddler or similar tool to manually stitch together the original HTML with the Ajax HTML. This is probably more trouble than it's worth, and is error prone, but it's one more possibility.

[Original response here to the original question]

Fiddler (http://www.fiddlertool.com/) is a free, browser-independent tool which works very well to fetch the exact HTML received by a browser. It shows you exact bytes on the wire as well as decoded/unzipped/etc content which you can feed into any HTML analysis tool. It also shows headers, timings, HTTP status, and lots of other good stuff.

You can also use fiddler to copy and rebuild requests if you want to test how a server responds to slightly different headers.

Fiddler works as a proxy server, sitting in between your browser and the website, and logs traffic going both ways.

You might have the CLASSPATH environment variable already added!!

Use following to avoid further usage of -cp . in java -cp . CLASSFILE

Add . to CLASSPATH in system properties->environment variables or by cmd

set CLASSPATH=%CLASSPATH%;.;

This is significantly faster than the EXISTS way:

SELECT [EmailAddress], [CustomerName] FROM [Customers] WHERE [EmailAddress] IN
  (SELECT [EmailAddress] FROM [Customers] GROUP BY [EmailAddress] HAVING COUNT(*) > 1)

This is what I use in my application:

static void Main()
{
  bool mutexCreated = false;
  System.Threading.Mutex mutex = new System.Threading.Mutex( true, @"Local\slimCODE.slimKEYS.exe", out mutexCreated );

  if( !mutexCreated )
  {
    if( MessageBox.Show(
      "slimKEYS is already running. Hotkeys cannot be shared between different instances. Are you sure you wish to run this second instance?",
      "slimKEYS already running",
      MessageBoxButtons.YesNo,
      MessageBoxIcon.Question ) != DialogResult.Yes )
    {
      mutex.Close();
      return;
    }
  }

  // The usual stuff with Application.Run()

  mutex.Close();
}

It is kind of late for answer, but maybe it helps someone in future. I found it easier to use struct for this kind of problem.

Using Visual Studio

1. Attach a debugger to the process (e.g. start with debugging or Debug > Attach to process)
2. While debugging, show the Modules window (Debug > Windows > Modules)

This gives details about each assembly, app domain and has a few options to load symbols (i.e. pdb files that contain debug information).

Using Process Explorer

If you want an external tool you can use the Process Explorer (freeware, published by Microsoft)

Click on a process and it will show a list with all the assemblies used. The tool is pretty good as it shows other information such as file handles etc.

Programmatically

Check this SO question that explains how to do it.

You will have to use JavaScript. The browser will only send the value of the selected option (so its not PHP's fault).

What your JS should do is hook into the form's submit event and create a hidden field with the value of the selected option's stud_name value. This hidden field will then get sent to the server.

That being said ... you shouldn't relay on the client to provide the correct data. You already know what stud_name should be for a given value on the server (since you are outputting it). So just apply the same logic when you are processing the form.

we can classify these under different two broad groups static binding and dynamic binding. It is based on when the binding is done with the corresponding values. If the references are resolved at compile time, then it is static binding and if the references are resolved at runtime then it is dynamic binding. Static binding and dynamic binding also called as early binding and late binding. Sometimes they are also referred as static polymorphism and dynamic polymorphism.

By lines I assume you mean rows in the table person. What you're looking for is:

select p.name
from   person p
where  p.name LIKE '%A%'; --contains the character 'A'

The above is case sensitive. For a case insensitive search, you can do:

select p.name
from   person p
where  UPPER(p.name) LIKE '%A%'; --contains the character 'A' or 'a'

For the special character, you can do:

select p.name
from   person p
where  p.name LIKE '%'||chr(8211)||'%'; --contains the character chr(8211)

The LIKE operator matches a pattern. The syntax of this command is described in detail in the Oracle documentation. You will mostly use the % sign as it means match zero or more characters.

If the string contains UTF-8 characters outside of the ASCII range, then boost::algorithm::to_lower will not convert those. Better use boost::locale::to_lower when UTF-8 is involved. See http://www.boost.org/doc/libs/1_51_0/libs/locale/doc/html/conversions.html

The following will cover all browsers worth covering:

text-shadow: 0 0 2px #fff; /* Firefox 3.5+, Opera 9+, Safari 1+, Chrome, IE10 */
filter: progid:DXImageTransform.Microsoft.Glow(Color=#ffffff,Strength=1); /* IE<10 */

To read a line from a file, you should use the fgets function: It reads a string from the specified file up to either a newline character or EOF.

The use of sscanf in your code would not work at all, as you use filename as your format string for reading from line into a constant string literal %s.

The reason for SEGV is that you write into the non-allocated memory pointed to by line.

Using subList(30, 38); will fail because max index 38 is not available in list, so its not possible.

Only way may be before asking for the sublist, you explicitly determine the max index using list size() method.

for example, check size, which returns 35, so call sublist(30, size());

OR

COPIED FROM pb2q comment

dataList = dataList.subList(30, 38 > dataList.size() ? dataList.size() : 38);

I can speak from first hand experience that it is often a good idea to place the web server and database on different machines. If you have an application that is resource intensive, it can easily cause the CPU cycles on the machine to peak, essentially bringing the machine to a halt. However, if your application has limited use of the database, it would probably be no big deal to have them share a server.

You could read jQuery creator John Resig's post about it here: http://ejohn.org/blog/picking-time/.

To revert modified files:

sudo svn revert
svn status|grep "^ *M" | sed -e 's/^ *M *//'

The 'c' means it's a character device. tty is a special file representing the 'controlling terminal' for the current process.

Character Devices

Unix supports 'device files', which aren't really files at all, but file-like access points to hardware devices. A 'character' device is one which is interfaced byte-by-byte (as opposed to buffered IO).

TTY

/dev/tty is a special file, representing the terminal for the current process. So, when you echo 1 > /dev/tty, your message ('1') will appear on your screen. Likewise, when you cat /dev/tty, your subsequent input gets duplicated (until you press Ctrl-C).

/dev/tty doesn't 'contain' anything as such, but you can read from it and write to it (for what it's worth). I can't think of a good use for it, but there are similar files which are very useful for simple IO operations (e.g. /dev/ttyS0 is normally your serial port)

This quote is from http://tldp.org/HOWTO/Text-Terminal-HOWTO-7.html#ss7.3 :

/dev/tty stands for the controlling terminal (if any) for the current process. To find out which tty's are attached to which processes use the "ps -a" command at the shell prompt (command line). Look at the "tty" column. For the shell process you're in, /dev/tty is the terminal you are now using. Type "tty" at the shell prompt to see what it is (see manual pg. tty(1)). /dev/tty is something like a link to the actually terminal device name with some additional features for C-programmers: see the manual page tty(4).

Here is the man page: http://linux.die.net/man/4/tty

ARP:

for ip in $(seq 1 254); do arp -n 10.185.0.$ip | grep Address; [ $? -eq 0 ] && echo "10.185.0.$ip UP" || : ; done

You can't do this no. There is one attribute selector that matches exactly or partial until a - sign, but it wouldn't work here because you have multiple attributes. If the class name you are looking for would always be first, you could do this:

<html>
<head>
<title>Test Page</title>
<style type="text/css">
div[class|=status] { background-color:red; }
</style>
</head>
<body>
<div id='A' class='status-important bar-class'>A</div>
<div id='B' class='bar-class'>B</div>
<div id='C' class='status-low-priority bar-class'>C</div>

</body>
</html>

Note that this is just to point out which CSS attribute selector is the closest, it is not recommended to assume class names will always be in front since javascript could manipulate the attribute.

Using in place string concatenation by '+' is THE WORST method of concatenation in terms of stability and cross implementation as it does not support all values. PEP8 standard discourages this and encourages the use of format(), join() and append() for long term use.

As quoted from the linked "Programming Recommendations" section:

For example, do not rely on CPython's efficient implementation of in-place string concatenation for statements in the form a += b or a = a + b. This optimization is fragile even in CPython (it only works for some types) and isn't present at all in implementations that don't use refcounting. In performance sensitive parts of the library, the ''.join() form should be used instead. This will ensure that concatenation occurs in linear time across various implementations.

The ideas on this page were helpful, yet as ever my scenario was different. So, in modal bootstrap / express node js / aws beanstalk, this worked for me:

var modal = $(this);
modal.find(".modal-body select#cJourney").val(vcJourney).attr("selected","selected");

Where my select ID = "cJourney" and the drop down value was stored in variable: vcJourney

As noted in the release email, linked to from the release tweet and noted in large orange warning that appears on the front page of the documentation, and less orange, but still present, in the readme on the repository and the release on pypi:

xlrd has explicitly removed support for anything other than xls files.

In your case, the solution is to:

• make sure you are on a recent version of Pandas, at least 1.0.1, and preferably the latest release. 1.2 will make his even clearer.
• install openpyxl: https://openpyxl.readthedocs.io/en/stable/
• change your Pandas code to be:

  df1 = pd.read_excel(
       os.path.join(APP_PATH, "Data", "aug_latest.xlsm"),
       engine='openpyxl',
  )

So, take a look here: http://www.microbion.co.uk/web/vertline.htm This link will give you a couple of tips.

The read_sql docs say this params argument can be a list, tuple or dict (see docs).

To pass the values in the sql query, there are different syntaxes possible: ?, :1, :name, %s, %(name)s (see PEP249).
But not all of these possibilities are supported by all database drivers, which syntax is supported depends on the driver you are using (psycopg2 in your case I suppose).

In your second case, when using a dict, you are using 'named arguments', and according to the psycopg2 documentation, they support the %(name)s style (and so not the :name I suppose), see http://initd.org/psycopg/docs/usage.html#query-parameters.
So using that style should work:

df = psql.read_sql(('select "Timestamp","Value" from "MyTable" '
                     'where "Timestamp" BETWEEN %(dstart)s AND %(dfinish)s'),
                   db,params={"dstart":datetime(2014,6,24,16,0),"dfinish":datetime(2014,6,24,17,0)},
                   index_col=['Timestamp'])

Indeed, there is no defined standard. To support that information, have a look at wikipedia, in the Query String chapter. There is the following comment:

While there is no definitive standard, most web frameworks allow multiple values to be associated with a single field.[3][4]

Furthermore, when you take a look at the RFC 3986, in section 3.4 Query, there is no definition for parameters with multiple values.

Most applications use the first option you have shown: http://server/action?id=a&id=b. To support that information, take a look at this Stackoverflow link, and this MSDN link regarding ASP.NET applications, which use the same standard for parameters with multiple values.

However, since you are developing the APIs, I suggest you to do what is the easiest for you, since the caller of the API will not have much trouble creating the query string.

The solution, if your list items can be display: inline is quite easy:

#footer { text-align: center; }
#footer ul { list-style: none; }
#footer ul li { display: inline; }

However, many times you must use display:block on your <li>s. The following CSS will work, in this case:

#footer { width: 100%; overflow: hidden; }
#footer ul { list-style: none; position: relative; float: left; display: block; left: 50%; }
#footer ul li { position: relative; float: left; display: block; right: 50%; }

The PHP code is executed on the server, so your redirect is executed before the browser even sees the JavaScript.

You need to do the redirect in JavaScript too

$('.entry a:first').click(function()
{
    window.location.replace("http://www.google.com");
});

in Swift 4.2 this works.

import Foundation

class myThread: Thread
{
    override func main() {
        while(true) {
            print("Running in the Thread");
            Thread.sleep(forTimeInterval: 4);
        }
    }
}

let t = myThread();
t.start();

while(true) {
    print("Main Loop");
    sleep(5);
}

It is working fine for me, but with a different command:

root@ubuntu:/usr/bin# sudo apt-get install sun-java6

Error message:

Couldn't find package sun-java6.

root@ubuntu:/usr/bin# sudo apt-get install sun-java*

Bam, it worked.

If you don't know which option to enter the params. Just want to keep the default value like on_delete=None before migration:

on_delete=models.CASCADE

This is a code snippet in the old version:

if on_delete is None:
    warnings.warn(
        "on_delete will be a required arg for %s in Django 2.0. Set "
        "it to models.CASCADE on models and in existing migrations "
        "if you want to maintain the current default behavior. "
        "See https://docs.djangoproject.com/en/%s/ref/models/fields/"
        "#django.db.models.ForeignKey.on_delete" % (
            self.__class__.__name__,
            get_docs_version(),
        ),
        RemovedInDjango20Warning, 2)
    on_delete = CASCADE

No need of any manual break in code. Just add \n where you want to break.

alert ("Please Select file \n to delete");

This will show the alert like

Please select file 
to delete.

Link with -static. When you link with -static the linker embeds the library inside the executable, so the executable will be bigger, but it can be executed on a system with an older version of glibc because the program will use it's own library instead of that of the system.

find with xargs is preferred when there are many potential matches to sift through. It runs more slowly than other options, but it always works. As some have discovered,xargs does not handle files with embedded spaces by default. You can overcome this by specifying the -d option.

Here is @RobEarl's answer, enhanced so it handles files with spaces:

find / -type f | xargs -d '\n' grep 'text-to-find-here'

Here is @venkat's answer, similarly enhanced:

find . -name "*.txt" | xargs -d '\n' grep -i "text_pattern"

Here is @Gert van Biljon's answer, similarly enhanced:

find . -type f -name "*.*" -print0 | xargs -d '\n' --null grep --with-filename --line-number --no-messages --color --ignore-case "searthtext"

Here is @LetalProgrammer's answer, similarly enhanced:

alias ffind find / -type f | xargs -d '\n' grep

Here is @Tayab Hussain's answer, similarly enhanced:

find . | xargs -d '\n' grep 'word' -sl

Here's a method I use which works and is easy to implement. This will require both the fpdf and fpdi libraries which can be downloaded here:

• FPDF: http://www.fpdf.org/en/download.php
• FPDI: https://www.setasign.com/products/fpdi/downloads

require('fpdf.php');
require('fpdi.php');

$files = ['doc1.pdf', 'doc2.pdf', 'doc3.pdf'];

$pdf = new FPDI();

foreach ($files as $file) {
    $pdf->setSourceFile($file);
    $tpl = $pdf->importPage(1, '/MediaBox');
    $pdf->addPage();
    $pdf->useTemplate($tpl);
}

$pdf->Output('F','merged.pdf');

You can do something like this to check if any mysql process is running or not:

ps aux | grep mysqld
ps aux | grep mysql

Then if it is running you can killall by using(depending on what all processes are running currently):

killall -9 mysql
killall -9 mysqld
killall -9 mysqld_safe    

First, please do not use extract(), it can be a security problem because it is easy to manipulate POST parameters

In addition, you don't have to use variable variable names (that sounds odd), instead:

foreach($_POST as $key => $value) {
  echo "POST parameter '$key' has '$value'";
}

To ensure that you have only parameters beginning with 'item_name' you can check it like so:

$param_name = 'item_name';
if(substr($key, 0, strlen($param_name)) == $param_name) {
  // do something
}

t.Log() will not show up until after the test is complete, so if you're trying to debug a test that is hanging or performing badly it seems you need to use fmt.

Yes: that was the case up to Go 1.13 (August 2019) included.

And that was followed in golang.org issue 24929

Consider the following (silly) automated tests:

func TestFoo(t *testing.T) {
    t.Parallel()

  for i := 0; i < 15; i++ {
        t.Logf("%d", i)
        time.Sleep(3 * time.Second)
    }
}

func TestBar(t *testing.T) {
    t.Parallel()

  for i := 0; i < 15; i++ {
        t.Logf("%d", i)
        time.Sleep(2 * time.Second)
    }
}

func TestBaz(t *testing.T) {
    t.Parallel()

  for i := 0; i < 15; i++ {
        t.Logf("%d", i)
        time.Sleep(1 * time.Second)
    }
}

If I run go test -v, I get no log output until all of TestFoo is done, then no output until all of TestBar is done, and again no more output until all of TestBaz is done.
This is fine if the tests are working, but if there is some sort of bug, there are a few cases where buffering log output is problematic:

• When iterating locally, I want to be able to make a change, run my tests, see what's happening in the logs immediately to understand what's going on, hit CTRL+C to shut the test down early if necessary, make another change, re-run the tests, and so on.
  If TestFoo is slow (e.g., it's an integration test), I get no log output until the very end of the test. This significantly slows down iteration.
• If TestFoo has a bug that causes it to hang and never complete, I'd get no log output whatsoever. In these cases, t.Log and t.Logf are of no use at all.
  This makes debugging very difficult.
• Moreover, not only do I get no log output, but if the test hangs too long, either the Go test timeout kills the test after 10 minutes, or if I increase that timeout, many CI servers will also kill off tests if there is no log output after a certain amount of time (e.g., 10 minutes in CircleCI).
  So now my tests are killed and I have nothing in the logs to tell me what happened.

But for (possibly) Go 1.14 (Q1 2020): CL 127120

testing: stream log output in verbose mode

The output now is:

=== RUN   TestFoo
=== PAUSE TestFoo
=== RUN   TestBar

=== PAUSE TestGaz
=== CONT  TestFoo
    TestFoo: main_test.go:14: hello from foo

It is indeed in Go 1.14, as Dave Cheney attests in "go test -v streaming output":

In Go 1.14, go test -v will stream t.Log output as it happens, rather than hoarding it til the end of the test run.

Under Go 1.14 the fmt.Println and t.Log lines are interleaved, rather than waiting for the test to complete, demonstrating that test output is streamed when go test -v is used.

Advantage, according to Dave:

This is a great quality of life improvement for integration style tests that often retry for long periods when the test is failing.
Streaming t.Log output will help Gophers debug those test failures without having to wait until the entire test times out to receive their output.

I handle it in the following way:

<html>
    <body>

        <form method="post" action="/">

                <input type="submit" value="Encrypt" name="Encrypt"/>
                <input type="submit" value="Decrypt" name="Decrypt" />

        </form>
    </body>
</html>
    

Python Code :

    from flask import Flask, render_template, request
    
    
    app = Flask(__name__)
    
    
    @app.route("/", methods=['GET', 'POST'])
    def index():
        print(request.method)
        if request.method == 'POST':
            if request.form.get('Encrypt') == 'Encrypt':
                # pass
                print("Encrypted")
            elif  request.form.get('Decrypt') == 'Decrypt':
                # pass # do something else
                print("Decrypted")
            else:
                # pass # unknown
                return render_template("index.html")
        elif request.method == 'GET':
            # return render_template("index.html")
            print("No Post Back Call")
        return render_template("index.html")
    
    
    if __name__ == '__main__':
        app.run()

The procedure name should be in caps while creating procedure in database. You may use small letters for your procedure name while calling from Java class like:

String getDBUSERByUserIdSql = "{call getDBUSERByUserId(?,?,?,?)}";

In database the name of procedure should be:

GETDBUSERBYUSERID    -- (all letters in caps only)

This serves as one of the solutions for this problem.

on OSX mountain Lion: If you have brew installed, then brew install mysql and follow the instructions on creating a test database with mysql on your machine. You don't have to go all the way through, I didn't need to After I did that I was able to bundle install and rake.

I know in the question you state "I assume JavaScript is used to create this effect" but CSS can be used too, an example is below.

CSS

.fancy-link {
   color: #333333;
   text-decoration: none;
   transition: color 0.3s linear;
   -webkit-transition: color 0.3s linear;
   -moz-transition: color 0.3s linear;
}

.fancy-link:hover {
   color: #F44336;
}

HTML

<a class="fancy-link" href="#">My Link</a>

And here is a JSFIDDLE for the above code!

Marcel in one of the answers points out you can "transition multiple CSS properties" you can also use "all" to effect the element with all your :hover styles like below.

CSS

.fancy-link {
   color: #333333;
   text-decoration: none;
   transition: all 0.3s linear;
   -webkit-transition: all 0.3s linear;
   -moz-transition: all 0.3s linear;
}

.fancy-link:hover {
   color: #F44336;
   padding-left: 10px;
}

HTML

<a class="fancy-link" href="#">My Link</a>

And here is a JSFIDDLE for the "all" example!

This occurs because of this issue also i.e repackaging which you defined in POM file.

Remove this from pom file under maven plugin. It will work

<executions>
    <execution>
        <goals>
             <goal>repackage</goal>
        </goals>
    </execution>
</executions>

It it possible to do in the admin, but there is not a very straightforward way to it. Also, I would like to advice to keep most business logic in your models, so you won't be dependent on the Django Admin.

Maybe it would be easier (and maybe even better) if you have the two seperate fields on your model. Then add a method on your model that combines them.

For example:

class MyModel(models.model):

    field1 = models.CharField(max_length=10)
    field2 = models.CharField(max_length=10)

    def combined_fields(self):
        return '{} {}'.format(self.field1, self.field2)

Then in the admin you can add the combined_fields() as a readonly field:

class MyModelAdmin(models.ModelAdmin):

    list_display = ('field1', 'field2', 'combined_fields')
    readonly_fields = ('combined_fields',)

    def combined_fields(self, obj):
        return obj.combined_fields()

If you want to store the combined_fields in the database you could also save it when you save the model:

def save(self, *args, **kwargs):
    self.field3 = self.combined_fields()
    super(MyModel, self).save(*args, **kwargs)

From the doc:

jqXHR.done(function( data, textStatus, jqXHR ) {});

An alternative construct to the success callback option, the .done() method replaces the deprecated jqXHR.success() method. Refer to deferred.done() for implementation details.

The point it is just an alternative for success callback option, and jqXHR.success() is deprecated.

I guess the problem is your js runs before the html is loaded.

If you are using jquery, you can use the document ready function to wrap your code:

$(function() {
    var Grid = function(width, height) {
        // codes...
    }
});

Or simply put your js after the <canvas>.

If you have a simple object you can iterate through it using the following code:

let myObj = {
  abc: '...',
  bca: '...',
  zzz: '...',
  xxx: '...',
  ccc: '...',
  // ...
};

let objKeys = Object.keys(myObj);

//Now we can use objKeys to iterate over myObj

for (item of objKeys) {
  //this will print out the keys
  console.log('key:', item);
  
  //this will print out the values 
  console.log('value:', myObj[item]);
}

If you have a nested object you can iterate through it using the following code:

let b = {
  one: {
    a: 1,
    b: 2,
    c: 3
  },
  two: {
    a: 4,
    b: 5,
    c: 6
  },
  three: {
    a: 7,
    b: 8,
    c: 9
  }
};

let myKeys = Object.keys(b);

for (item of myKeys) {
  //print the key
  console.log('Key', item)
  
  //print the value (which will be another object)
  console.log('Value', b[item])
  
  //print the nested value
  console.log('Nested value', b[item]['a'])
}

If you have array of objects you can iterate through it using the following code:

let c = [
{
  a: 1,
  b: 2
},
{
  a: 3,
  b: 4
}
];

for(item of c){
//print the whole object individually 
console.log('object', item);

//print the value inside the object
console.log('value', item['a']);
}

Closing Visual Studio Code (that in my case has an auto-uploader background job running on file-save) solved the issue for me.

Credit for the solution: my friend and colleague Arnel.

The difference is not just for Chrome but for most of the web browsers.

F5 refreshes the web page and often reloads the same page from the cached contents of the web browser. However, reloading from cache every time is not guaranteed and it also depends upon the cache expiry.

Shift + F5 forces the web browser to ignore its cached contents and retrieve a fresh copy of the web page into the browser.

Shift + F5 guarantees loading of latest contents of the web page.
However, depending upon the size of page, it is usually slower than F5.

You may want to refer to: What requests do browsers' "F5" and "Ctrl + F5" refreshes generate?

please use :

I was able to fix this by doing two things, though you may not have to do step 1.

1. copy from cygwin ssh.exe and all cyg*.dll into Git's bin directory (this may not be necessary but it is a step I took but this alone did not fix things)

2. follow the steps from: http://zylstra.wordpress.com/2008/08/29/overcome-herokus-permission-denied-publickey-problem/

   I added some details to my ~/.ssh/config file:

Host heroku.com
Hostname heroku.com
Port 22
IdentitiesOnly yes
IdentityFile ~/.ssh/id_heroku
TCPKeepAlive yes
User brandon

I had to use User as my email address for heroku.com Note: this means you need to create a key, I followed this to create the key and when it prompts for the name of the key, be sure to specify id_heroku http://help.github.com/win-set-up-git/

1. then add the key:
   heroku keys:add ~/.ssh/id_heroku.pub
