In my case Tomcat was running in a background. I've installed it as a external servlet while using Eclipse. With a Spring Boot in Intellij it has it own server but cannot start while it's already occupied.
In my case Tomcat starts automatically I turn on my OS, that is why I need to shut down him manualy:

$ sudo service tomcat stop

of course "tomcat" depends what version of tomcat you are using.
Hope it might help to someone.

A tool like systemtap (or a tracer) can monitor kernel signal-transmission logic and report. e.g., https://sourceware.org/systemtap/examples/process/sigmon.stp

# stap .../sigmon.stp -x 31994 SIGKILL
   SPID     SNAME            RPID  RNAME            SIGNUM SIGNAME
   5609     bash             31994 find             9      SIGKILL

The filtering if block in that script can be adjusted to taste, or eliminated to trace systemwide signal traffic. Causes can be further isolated by collecting backtraces (add a print_backtrace() and/or print_ubacktrace() to the probe, for kernel- and userspace- respectively).

With Android 8.0 using Custom Fonts in Application became easy with downloadable fonts. We can add fonts directly to the res/font/ folder in the project folder, and in doing so, the fonts become automatically available in Android Studio.

Now set fontFamily attribute to list of fonts or click on more and select font of your choice. This will add tools:fontFamily="@font/your_font_file" line to your TextView.

This will Automatically generate few files.

1. In values folder it will create fonts_certs.xml.

2. In Manifest it will add this lines:

  <meta-data
            android:name="preloaded_fonts"
            android:resource="@array/preloaded_fonts" /> 

3. preloaded_fonts.xml

<resources>
    <array name="preloaded_fonts" translatable="false">
        <item>@font/open_sans_regular</item>
        <item>@font/open_sans_semibold</item>
    </array>
</resources>

Another possible cause for this error message is if the HTTP Method is blocked by the server or load balancer.

It seems to be standard security practice to block unused HTTP Methods. We ran into this because HEAD was being blocked by the load balancer (but, oddly, not all of the load balanced servers, which caused it to fail only some of the time). I was able to test that the request itself worked fine by temporarily changing it to use the GET method.

The error code on iOS was: Error requesting App Code: Error Domain=NSURLErrorDomain Code=-1005 "The network connection was lost."

If I understood your question, you want to merge branchB into branchA. To do so, first checkout branchA like below,

git checkout branchA

Then execute the below command to merge branchB into branchA:

git merge branchB

There is the conditional expression:

a if cond else b

but this is an expression, not a statement.

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

if something: somefunc()
else: otherfunc()

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

You could do $stmt->queryString to obtain the SQL query used in the statement. If you want to save the entire $stmt variable (I can't see why), you could just copy it. It is an instance of PDOStatement so there is apparently no advantage in storing it.

Dim and Private work the same, though the common convention is to use Private at the module level, and Dim at the Sub/Function level. Public and Global are nearly identical in their function, however Global can only be used in standard modules, whereas Public can be used in all contexts (modules, classes, controls, forms etc.) Global comes from older versions of VB and was likely kept for backwards compatibility, but has been wholly superseded by Public.

Since you're using JPA, use the Lob annotation (and optionally the Column annotation). Here is what the JPA specification says about it:

9.1.19 Lob Annotation

A Lob annotation specifies that a persistent property or field should be persisted as a large object to a database-supported large object type. Portable applications should use the Lob annotation when mapping to a database Lob type. The Lob annotation may be used in conjunction with the Basic annotation. A Lob may be either a binary or character type. The Lob type is inferred from the type of the persistent field or property, and except for string and character-based types defaults to Blob.

So declare something like this:

@Lob 
@Column(name="CONTENT", length=512)
private String content;

• JPA 1.0 specification:
  • Section 9.1.19 "Lob Annotation"

You have a date with a known timezone (Here Europe/Madrid), and a target timezone (UTC)

You just need two SimpleDateFormats:

        long ts = System.currentTimeMillis();
        Date localTime = new Date(ts);

        SimpleDateFormat sdfLocal = new SimpleDateFormat ("yyyy/MM/dd HH:mm:ss");
        sdfLocal.setTimeZone(TimeZone.getTimeZone("Europe/Madrid"));

        SimpleDateFormat sdfUTC = new SimpleDateFormat ("yyyy/MM/dd HH:mm:ss");
        sdfUTC.setTimeZone(TimeZone.getTimeZone("UTC"));

        // Convert Local Time to UTC
        Date utcTime = sdfLocal.parse(sdfUTC.format(localTime));
        System.out.println("Local:" + localTime.toString() + "," + localTime.getTime() + " --> UTC time:" + utcTime.toString() + "-" + utcTime.getTime());

        // Reverse Convert UTC Time to Locale time
        localTime = sdfUTC.parse(sdfLocal.format(utcTime));
        System.out.println("UTC:" + utcTime.toString() + "," + utcTime.getTime() + " --> Local time:" + localTime.toString() + "-" + localTime.getTime());

So after see it working you can add this method to your utils:

    public Date convertDate(Date dateFrom, String fromTimeZone, String toTimeZone) throws ParseException {
        String pattern = "yyyy/MM/dd HH:mm:ss";
        SimpleDateFormat sdfFrom = new SimpleDateFormat (pattern);
        sdfFrom.setTimeZone(TimeZone.getTimeZone(fromTimeZone));

        SimpleDateFormat sdfTo = new SimpleDateFormat (pattern);
        sdfTo.setTimeZone(TimeZone.getTimeZone(toTimeZone));

        Date dateTo = sdfFrom.parse(sdfTo.format(dateFrom));
        return dateTo;
    }

SimpleDateFormat sdf = new SimpleDateFormat("MMM dd yyyy HH:mm:ss", Locale.ENGLISH);
//format as u want

try {
    String dateStart = "June 14 2018 16:02:37";
    cal.setTime(sdf.parse(dateStart));
    //all done
} catch (ParseException e) {
    e.printStackTrace();
}

The Background property expects a Brush object, not a string. Change the type of the property to Brush and initialize it thus:

Background = new SolidColorBrush(Colors.Red);

Many solutions have been posted and I'd like to contribute with mine, which works for a different number of columns in the CSV file. It creates a dictionary with one key per column, and the value for each key is a list with the elements in such column.

    input_file = csv.DictReader(open(path_to_csv_file))
    csv_dict = {elem: [] for elem in input_file.fieldnames}
    for row in input_file:
        for key in csv_dict.keys():
            csv_dict[key].append(row[key])

Here is how I encountered the error:

import os

path = input("Input file path: ")

name, ext = os.path.basename(path).rsplit('.', 1)
dire = os.path.dirname(path)

with open(f"{dire}\\{name} temp.{ext}", 'wb') as file:
    pass

It works great if the user inputs a file path with more than one element, like

C:\\Users\\Name\\Desktop\\Folder

But I thought that it would work with an input like

file.txt

as long as file.txt is in the same directory of the python file. But nope, it gave me that error, and I realized that the correct input should've been

.\\file.txt

In my case there was problem in URL. I've use https://example.com - but they ensure 'www.' - so when i switched to https://www.example.com everything was ok. The proper header was sent 'Host: www.example.com'.

You can try make a request in firefox brwoser, persist it and copy as cURL - that how I've found it.

None of the above answers solved it for me.

I cant even find the 'libraries' folder in my xampp - ubuntu also.

So, I simply restarted using the following commands:

sudo service apache2 restart

and

sudo service mysql restart

• Just restarted apache and mysql. Logged in phpmyadmin again and it worked as usual.

Thanks me..!!

Add a new pandas.Series using pandas.DataFrame.append().

If you wish to specify the name (AKA the "index") of the new row, use:

df.append(pandas.Series(name='NameOfNewRow'))

If you don't wish to name the new row, use:

df.append(pandas.Series(), ignore_index=True)

where df is your pandas.DataFrame.

Boilerplate is what good programmers avoid: repetition.

For Visual Studio 2005:

If you do have an installed Visual Studio 2005 however, and want to find out the serial number you’ve used to install it because you don’t have a clue where you put that shiny sticker, you can. It is, like most things in Windows, in the registry.

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\8.0\Registration\PIDKEY

In order to convert the value in that key to an actual serial number you have to put a dash ( – ) after evert 5 characters of the code.

From: http://www.gooli.org/blog/visual-studio-2005-serial-number/

For Visual Studio 2008 it's supposed to be:

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\VisualStudio\9.0\Registration\PIDKEY

However I noted that the the Data field for PIDKEY is only filled in the 1000.0x000 (or 2000.0x000) sub folder of the above paths.

declare your asyncTask in your activity:

private YourAsyncTask mTask;

instantiate it like this:

mTask = new YourAsyncTask().execute();

kill/cancel it like this:

mTask.cancel(true);

holy errors The reason for the code below is to show how to not void main every function and not to type return; for functions...... instead push everything into the sediment for which is the print function prototype... if you need to use useful functions ... you will have to below..... (p.s. this below is for people overwhelmed by these object and T templates which allow different variable declaration types(such as float and char) to use the same passed by value in a user defined function)

char arr[ ] = "This is a test";

string str(arr);


//  You can also assign directly to a string.
str = "This is another string";

can anyone tell me why c++ made arrays into pass by value one at a time and the only way to eliminate spaces and punctuation is the use of string tokens. I couldn't get around the problem when i was trying to delete spaces for a palindrome...

#include <iostream>
#include <iomanip>
using namespace std;
int getgrades(float[]);
int getaverage(float[], float);
int calculateletters(float[], float, float, float[]);
int printResults(float[], float, float, float[]);


int main()
{

int i;
float  maxSize=3, size;
float  lettergrades[5], numericgrades[100], average;

size=getgrades(numericgrades);
average = getaverage(numericgrades, size);
printResults(numericgrades, size, average, lettergrades);
return 0;
}

int getgrades(float a[])
{ 


int i, max=3;

for (i = 0; i <max; i++)
{
    //ask use for input
    cout << "\nPlease Enter grade " << i+1 << " : ";
    cin >> a[i];
    //makes sure that user enters a vlue between 0 and 100

   if(a[i] < 0 || a[i] >100)
    {
        cout << "Wrong input. Please
 enter a value between 0 and 100 only." << endl;
        cout << "\nPlease Reenter grade " << i+1 << " : ";
        cin >> a[i];

        return i;
    }
}
}

int getaverage(float a[], float n) 
{ 
int i;
float sum = 0;
 if (n == 0)
return 0;
for (i = 0; i < n; i++)
sum += a[i];
return sum / n;
}                               


int printResults(float a[], float n, float average, float letters[]) 
{
int i;
cout << "Index Number | input  |
array values address in memory " << endl;

for (i = 0; i < 3; i++)
{
cout <<"     "<< i<<" \t\t"<<setprecision(3)<<
a[i]<<"\t\t" << &a[i] << endl;
}
cout<<"The average of your grades is: "<<setprecision(3)<<average<<endl;

}

The right choice really depends on how big the input string is and what the perforce and memory requirement are, but I would use a regular expression like

string result = Regex.Replace(s, @"\r\n?|\n|\t", String.Empty);

Or if we need to apply the same replacement multiple times, it is better to use a compiled version for the Regex like

var regex = new Regex(@"\r\n?|\n|\t", RegexOptions.Compiled); 
string result = regex.Replace(s, String.Empty);

NOTE: different scenarios requite different approaches to achieve the best performance and the minimum memory consumption

If you can avoid the need for concurrent writes to a single file, it sounds like you do not need a database to store the chat messages.

Just append the conversation to a text file (1 file per user\conversation). and have a directory/ file structure

Here's a simplified view of the file structure:

chat-1-bob.txt
        201101011029, hi
        201101011030, fine thanks.

chat-1-jen.txt
        201101011030, how are you?
        201101011035, have you spoken to bill recently?

chat-2-bob.txt
        201101021200, hi
        201101021222, about 12:22
chat-2-bill.txt
        201101021201, Hey Bob,
        201101021203, what time do you call this?

You would then only need to store the userid, conversation id (guid ?) & a reference to the file name.

I think you will find it hard to get a more simple scaleable solution.

You can use LOAD_FILE to get the data too see: http://dev.mysql.com/doc/refman/5.0/en/string-functions.html

If you have a requirement to rebuild a conversation you will need to put a value (date time) alongside your sent chat message (in the file) to allow you to merge & sort the files, but at this point it is probably a good idea to consider using a database.

• START_STICKY: It will restart the service in case if it terminated and the Intent data which is passed to the onStartCommand() method is NULL. This is suitable for the service which are not executing commands but running independently and waiting for the job.
• START_NOT_STICKY: It will not restart the service and it is useful for the services which will run periodically. The service will restart only when there are a pending startService() calls. It’s the best option to avoid running a service in case if it is not necessary.
• START_REDELIVER_INTENT: It’s same as STAR_STICKY and it recreates the service, call onStartCommand() with last intent that was delivered to the service.

The ConcurentLinkedQueue is a very efficient wait/lock free implementation (see the javadoc for reference), so not only you don't need to synchronize, but the queue will not lock anything, thus being virtually as fast as a non synchronized (not thread safe) one.

You can link libraries from cdn (Content delivery network):

<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap-theme.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>

Or link libraries locally, add css files in the css folder and jquery in js folder. You have to keep both folders in the laravel public folder then you can link like below:

<link rel="stylesheet" href="{{asset('css/bootstrap-theme.min.css')}}">
<script src="{{asset('js/jquery.min.js')}}"></script>

or else

{{ HTML::style('css/style.css') }}
{{ HTML::script('js/functions.js') }}

If you link js files and css files locally (like in the last two examples) you need to add js and css files to the js and css folders which are in public\js or public\css not in resources\assets.

Here's another instance similar to the examples above that you may only have one config file define where CORS is: There were two web.config files on the IIS server on the path in different directories, and one of them was hidden in the virtual directory. To solve it I deleted the root level config file since the path was using the config file in the virtual directory. Have to choose one or the other.

URL called:  'https://example.com/foo/bar'
                     ^              ^
      CORS config file in root      virtual directory with another CORS config file
          deleted this config             other sites using this

$UUID_RE = join '-', map { "[0-9a-f]{$_}" } 8, 4, 4, 4, 12;

BTW, allowing only 4 on one of the positions is only valid for UUIDv4. But v4 is not the only UUID version that exists. I have met v1 in my practice as well.

Using Dataservice we can call the function from another component

Component1: The component which we are calling the function

constructor( public bookmarkRoot: dataService ) { } 

onClick(){
     this.bookmarkRoot.callToggle.next( true );
}

dataservice.ts

import { Injectable } from '@angular/core';
@Injectable()
export class dataService {
     callToggle = new Subject();
}

Component2:The component which contains the function

constructor( public bookmarkRoot: dataService ) { 
  this.bookmarkRoot.callToggle.subscribe(( data ) => {
            this.closeDrawer();
        } )
} 

 closeDrawer() {
        console.log("this is called")
    }

Check the version of the excel, if you are using older version then Value2 is not available for you and thus it is showing an error, while it will work with 2007+ version. Or the other way, the object is not getting created and thus the Value2 property is not available for the object.

Simple command to check keras version:

(py36) C:\WINDOWS\system32>python
Python 3.6.8 |Anaconda custom (64-bit) 

>>> import keras
Using TensorFlow backend.
>>> keras.__version__
'2.2.4'

The fork(),vfork() and clone() all call the do_fork() to do the real work, but with different parameters.

asmlinkage int sys_fork(struct pt_regs regs)
{
    return do_fork(SIGCHLD, regs.esp, &regs, 0);
}

asmlinkage int sys_clone(struct pt_regs regs)
{
    unsigned long clone_flags;
    unsigned long newsp;

    clone_flags = regs.ebx;
    newsp = regs.ecx;
    if (!newsp)
        newsp = regs.esp;
    return do_fork(clone_flags, newsp, &regs, 0);
}
asmlinkage int sys_vfork(struct pt_regs regs)
{
    return do_fork(CLONE_VFORK | CLONE_VM | SIGCHLD, regs.esp, &regs, 0);
}
#define CLONE_VFORK 0x00004000  /* set if the parent wants the child to wake it up on mm_release */
#define CLONE_VM    0x00000100  /* set if VM shared between processes */

SIGCHLD means the child should send this signal to its father when exit.

For fork, the child and father has the independent VM page table, but since the efficiency, fork will not really copy any pages, it just set all the writeable pages to readonly for child process. So when child process want to write something on that page, an page exception happen and kernel will alloc a new page cloned from the old page with write permission. That's called "copy on write".

For vfork, the virtual memory is exactly by child and father---just because of that, father and child can't be awake concurrently since they will influence each other. So the father will sleep at the end of "do_fork()" and awake when child call exit() or execve() since then it will own new page table. Here is the code(in do_fork()) that the father sleep.

if ((clone_flags & CLONE_VFORK) && (retval > 0))
down(&sem);
return retval;

Here is the code(in mm_release() called by exit() and execve()) which awake the father.

up(tsk->p_opptr->vfork_sem);

For sys_clone(), it is more flexible since you can input any clone_flags to it. So pthread_create() call this system call with many clone_flags:

int clone_flags = (CLONE_VM | CLONE_FS | CLONE_FILES | CLONE_SIGNAL | CLONE_SETTLS | CLONE_PARENT_SETTID | CLONE_CHILD_CLEARTID | CLONE_SYSVSEM);

Summary: the fork(),vfork() and clone() will create child processes with different mount of sharing resource with the father process. We also can say the vfork() and clone() can create threads(actually they are processes since they have independent task_struct) since they share the VM page table with father process.

Just a slight addition to the above solution if you are having problem with downloaded file's name...

Response.AddHeader("Content-Disposition", "attachment; filename=\"" + file.Name + "\"");

This will return the exact file name even if it contains spaces or other characters.

playSound is a static method in your class, but you are referring to members like audioSounds or minTime which are not declared static so they would require a SoundManager sm = new SoundManager(); to operate as sm.audioSounds or sm.minTime respectively

Solution:

public static List<AudioSource> audioSounds = new List<AudioSource>();
public static double minTime = 0.5;

If you are using AngularJS, you can use a custom directive for easy access:

define(['angular'], function () {
    angular.module("selectionHelper", [])
    .directive('selectOnClick', function () {
        return {
            restrict: 'A',
            link: function (scope, element, attrs) {                
                element.on('click', function () {
                    this.select();
                });
            }
        };
    });
});

Now one can just use it like this:

<input type="text" select-on-click ... />

The sample is with requirejs - so the first and the last line can be skipped if using something else.

With the introduction of formatted string literals ("f-strings" for short) in Python 3.6, it is now possible to write this with a briefer syntax:

>>> name = "Fred"
>>> f"He said his name is {name}."
'He said his name is Fred.'

With the example given in the question, it would look like this

plot.savefig(f'hanning{num}.pdf')

If you don't specify the platform for the app you won't able to add app domain correctly.

Here is an example -- validate that its a type a website platform.

You could write a generic Pair<A, B> class and use this in an array or list. Yes, you have to write a class, but you can reuse the same class for all types, so you only have to do it once.

FOR SQL SERVER

No need to specify other parameters. You can go through this article.

It's called a favicon. It is inserted like this:

After all these months have passed after the original question, it's now worth pointing out that Microsoft has devised a solution of their own. See http://blogs.msdn.com/b/vbertocci/archive/2012/11/20/introducing-the-developer-preview-of-the-json-web-token-handler-for-the-microsoft-net-framework-4-5.aspx for details.

There are ways to handle your own signals in certain JVMs -- see this article about the HotSpot JVM for example.

By using the Sun internal sun.misc.Signal.handle(Signal, SignalHandler) method call you are also able to register a signal handler, but probably not for signals like INT or TERM as they are used by the JVM.

To be able to handle any signal you would have to jump out of the JVM and into Operating System territory.

What I generally do to (for instance) detect abnormal termination is to launch my JVM inside a Perl script, but have the script wait for the JVM using the waitpid system call.

I am then informed whenever the JVM exits, and why it exited, and can take the necessary action.

Regarding the internal structure of a Python long, check sys.int_info (or sys.long_info for Python 2.7).

>>> import sys
>>> sys.int_info
sys.int_info(bits_per_digit=30, sizeof_digit=4)

Python either stores 30 bits into 4 bytes (most 64-bit systems) or 15 bits into 2 bytes (most 32-bit systems). Comparing the actual memory usage with calculated values, I get

>>> import math, sys
>>> a=0
>>> sys.getsizeof(a)
24
>>> a=2**100
>>> sys.getsizeof(a)
40
>>> a=2**1000
>>> sys.getsizeof(a)
160
>>> 24+4*math.ceil(100/30)
40
>>> 24+4*math.ceil(1000/30)
160

There are 24 bytes of overhead for 0 since no bits are stored. The memory requirements for larger values matches the calculated values.

If your numbers are so large that you are concerned about the 6.25% unused bits, you should probably look at the gmpy2 library. The internal representation uses all available bits and computations are significantly faster for large values (say, greater than 100 digits).

Input is set the textvariable in the entry, which is the string variable and when I set the text of the string variable as "" this clears the text in the entry

The accepted answer gave two locations:

here

C:\Documents and Settings\Administrator\Local Settings\Temp\VWDWebCache

and possibly here

C:\Documents and Settings\Administrator\Local Settings\Application Data\Microsoft\WebsiteCache

Did you try those?

Edited to add

On my Windows Vista machine, it's located in

%Temp%\VWDWebCache

and in

%LocalAppData%\Microsoft\WebsiteCache

From your additional information (regarding team edition) this comes from Clear Client TFS Cache:

Clear Client TFS Cache

Visual Studio and Team Explorer provide a caching mechanism which can get out of sync. If I have multiple instances of a single TFS which can be connected to from a single Visual Studio client, that client can become confused.

To solve it..

For Windows Vista delete contents of this folder

%LocalAppData%\Microsoft\Team Foundation\1.0\Cache

Something like this should do it :

UPDATE table1 
   SET table1.Price = table2.price 
   FROM table1  INNER JOIN  table2 ON table1.id = table2.id

You can also try this:

UPDATE table1 
   SET price=(SELECT price FROM table2 WHERE table1.id=table2.id);

Answers so far haven't addressed the "entire stream" part of the question. I think the good way to do this is ioutil.ReadAll. With your io.ReaderCloser named rc, I would write,

Go >= v1.16

if b, err := io.ReadAll(rc); err == nil {
    return string(b)
} ...

Go <= v1.15

if b, err := ioutil.ReadAll(rc); err == nil {
    return string(b)
} ...

For function:

you can query the pg_proc view , just as the following

select proname,prosrc from pg_proc where proname= your_function_name; 

Another way is that just execute the commont \df and \ef which can list the functions.

skytf=> \df           
                                             List of functions
 Schema |         Name         | Result data type |              Argument data types               |  Type  
--------+----------------------+------------------+------------------------------------------------+--------
 public | pg_buffercache_pages | SETOF record     |                                                | normal


skytf=> \ef  pg_buffercache_pages

It will show the source code of the function.

For triggers:

I dont't know if there is a direct way to get the source code. Just know the following way, may be it will help you!

• step 1 : Get the table oid of the trigger:

    skytf=> select tgrelid from pg_trigger  where tgname='insert_tbl_tmp_trigger';
      tgrelid
    ---------
       26599
    (1 row)

• step 2: Get the table name of the above oid !

    skytf=> select oid,relname  from pg_class where oid=26599;
      oid  |           relname           
    -------+-----------------------------
     26599 | tbl_tmp
    (1 row)

• step 3: list the table information

    skytf=> \d tbl_tmp

It will show you the details of the trigger of the table . Usually a trigger uses a function. So you can get the source code of the trigger function just as the above that I pointed out !

I had the same issue, the following commands can resolve:

sudo yum install  glibc-common glibc  (mutual dependency)
sudo yum install  glibc.i686  (the missing version)

Try storing the state in a attribute on the element itself, such as superDirectiveStatus="true"

For example:

angular.module('app')
  .directive('superDirective', function ($compile, $injector) {
    return {
      restrict: 'A',
      replace: true,
      link: function compile(scope, element, attrs) {
        if (element.attr('datepicker')) { // check
          return;
        }
        var status = element.attr('superDirectiveStatus');
        if( status !== "true" ){
             element.attr('datepicker', 'someValue');
             element.attr('datepicker-language', 'en');
             // some more
             element.attr('superDirectiveStatus','true');
             $compile(element)(scope);

        }

      }
    };
  });

I hope this helps you.

This covers all conditions that you are looking for.

SELECT * from Product_sales where (From_date <= '2013-01-09' AND To_date >= '2013-01-01')

This problem arises due to the administrative share.

Here is the solution :

1. Set HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System DWORD value: LocalAccountTokenFilterPolicy to 1

2. Go to this link: http://www.snehashish.com/install-oracle-database-12c-software/ Follow 8th point.
   It helped me a lot.
   After creating the hidden share (c$) it should look like this (you can ignore the description tab)

And let me know if it worked or not.

Unicode is a standard that defines, along with ISO/IEC 10646, Universal Character Set (UCS) which is a superset of all existing characters required to represent practically all known languages.

Unicode assigns a Name and a Number (Character Code, or Code-Point) to each character in its repertoire.

UTF-8 encoding, is a way to represent these characters digitally in computer memory. UTF-8 maps each code-point into a sequence of octets (8-bit bytes)

For e.g.,

UCS Character = Unicode Han Character

UCS code-point = U+24B62

UTF-8 encoding = F0 A4 AD A2 (hex) = 11110000 10100100 10101101 10100010 (bin)

UPDATE - I do not have Total DNS enabled at GoDaddy because the domain is hosted at DiscountASP. As such, I could not add an A Record and that is why GoDaddy was only offering to forward my subdomain to a different site. I finally realized that I had to go to DiscountASP to add the A Record to point to DreamHost. Now waiting to see if it all works!

Of course, use the stinkin' IP! I'm not sure why that wasn't registering for me. I guess their helper text example of pointing to another url was throwing me off.

Thanks for both of the replies. I 'got it' as soon as I read Bryant's response which was first but Saif kicked it up a notch and added a little more detail.

Thanks!

Culprit is preflight request using OPTIONS method

For HTTP request methods that can cause side-effects on user data (in particular, for HTTP methods other than GET, or for POST usage with certain MIME types), the specification mandates that browsers "preflight" the request, soliciting supported methods from the server with an HTTP OPTIONS request method, and then, upon "approval" from the server, sending the actual request with the actual HTTP request method.

Web specification refer to: https://developer.mozilla.org/en-US/docs/Web/HTTP/Access_control_CORS

I resolved the problem by adding following lines in Nginx conf.

    location / {
               if ($request_method = OPTIONS ) {
                   add_header Access-Control-Allow-Origin  "*";
                   add_header Access-Control-Allow-Methods "POST, GET, PUT, UPDATE, DELETE, OPTIONS";
                   add_header Access-Control-Allow-Headers "Authorization";
                   add_header Access-Control-Allow-Credentials  "true";
                   add_header Content-Length 0;
                   add_header Content-Type text/plain;
                   return 200;
               }
    location ~ ^/(xxxx)$ {
                if ($request_method = OPTIONS) {
                    rewrite ^(.*)$ / last;
                }
    }

"Let's Build a Compiler" is awesome, but it's a bit outdated. (I'm not saying it makes it even a little bit less valid.)

Or check out SLANG. This is similar to "Let's Build a Compiler" but is a much better resource especially for beginners. This comes with a pdf tutorial which takes a 7 step approach at teaching you a compiler. Adding the quora link as it have the links to all the various ports of SLANG, in C++, Java and JS, also interpreters in python and java, originally written using C# and the .NET platform.

Functional approach with ES2015

Computing the difference between two arrays is one of the Set operations. The term already indicates that the native Set type should be used, in order to increase the lookup speed. Anyway, there are three permutations when you compute the difference between two sets:

[+left difference] [-intersection] [-right difference]
[-left difference] [-intersection] [+right difference]
[+left difference] [-intersection] [+right difference]

Here is a functional solution that reflects these permutations.

Left difference:

// small, reusable auxiliary functions_x000D_
_x000D_
const apply = f => x => f(x);_x000D_
const flip = f => y => x => f(x) (y);_x000D_
const createSet = xs => new Set(xs);_x000D_
const filter = f => xs => xs.filter(apply(f));_x000D_
_x000D_
_x000D_
// left difference_x000D_
_x000D_
const differencel = xs => ys => {_x000D_
  const zs = createSet(ys);_x000D_
  return filter(x => zs.has(x)_x000D_
     ? false_x000D_
     : true_x000D_
  ) (xs);_x000D_
};_x000D_
_x000D_
_x000D_
// mock data_x000D_
_x000D_
const xs = [1,2,2,3,4,5];_x000D_
const ys = [0,1,2,3,3,3,6,7,8,9];_x000D_
_x000D_
_x000D_
// run the computation_x000D_
_x000D_
console.log( differencel(xs) (ys) );

Right difference:

differencer is trivial. It is just differencel with flipped arguments. You can write a function for convenience: const differencer = flip(differencel). That's all!

Symmetric difference:

Now that we have the left and right one, implementing the symmetric difference gets trivial as well:

// small, reusable auxiliary functions_x000D_
_x000D_
const apply = f => x => f(x);_x000D_
const flip = f => y => x => f(x) (y);_x000D_
const concat = y => xs => xs.concat(y);_x000D_
const createSet = xs => new Set(xs);_x000D_
const filter = f => xs => xs.filter(apply(f));_x000D_
_x000D_
_x000D_
// left difference_x000D_
_x000D_
const differencel = xs => ys => {_x000D_
  const zs = createSet(ys);_x000D_
  return filter(x => zs.has(x)_x000D_
     ? false_x000D_
     : true_x000D_
  ) (xs);_x000D_
};_x000D_
_x000D_
_x000D_
// symmetric difference_x000D_
_x000D_
const difference = ys => xs =>_x000D_
 concat(differencel(xs) (ys)) (flip(differencel) (xs) (ys));_x000D_
_x000D_
// mock data_x000D_
_x000D_
const xs = [1,2,2,3,4,5];_x000D_
const ys = [0,1,2,3,3,3,6,7,8,9];_x000D_
_x000D_
_x000D_
// run the computation_x000D_
_x000D_
console.log( difference(xs) (ys) );

I guess this example is a good starting point to obtain an impression what functional programming means:

Programming with building blocks that can be plugged together in many different ways.

This is the simplest answer:

<?php
    $img = get_the_post_thumbnail_url($postID, 'post-thumbnail');
?>

Try executing it as sudo.

sudo laravel new blog

Your file may not have the appropriate permissions. Let us know if it worked!

I made this because I needed an easy way to split strings and c-based strings... Hopefully someone else can find it useful as well. Also it doesn't rely on tokens and you can use fields as delimiters, which is another key I needed.

I'm sure there's improvements that can be made to even further improve its elegance and please do by all means

    StringSplit ss = mystring;
    vector<string> Split = ss.split_string('|');

    for (int i = 0; i < Split.size(); i++)
    {
        cout << Split[i] << endl;
    }

    return 0;
}

To keep empty entries (by default empties will be excluded):

StringSplit ss = mystring;
ss.keep_empty = true;
vector<string> Split = ss.split_string(":DELIM:");

The goal was to make it similar to C#'s Split() method where splitting a string is as easy as:

String[] Split = 
    "Hey:cut:what's:cut:your:cut:name?".Split(new[]{":cut:"}, StringSplitOptions.None);

foreach(String X in Split)
{
    Console.Write(X);
}

I hope someone else can find this as useful as I do.

If you have a Microsoft Virtual WiFi Miniport Adapter as one of the available network adapters, you may do the following:

• Run Windows Command Processor (cmd) as Administrator
• Type: netsh wlan set hostednetwork mode=allow ssid=NAME key=PASSWORD
• Then: netsh wlan start hostednetwork
• Open "Control Panel\Network and Internet\Network Connections"
• Right-click on your active network adapter (the one that you use to connect on the internet) and then click Properties
• Then open Sharing tab
• Check "Allow other network users to connect..." and select your WiFi Miniport Adapter
• Once finished, type: netsh wlan stop hostednetwork

That's it!

Do not use ABSOLUTE PATH to refer to the name of the image for example: C:/xamp/www/Archivos/images/templatemo_image_02_opt_20160401-1244.jpg. You must use the reference to its location within webserver. For example using ../../Archivos/images/templatemo_image_02_opt_20160401-1244.jpg depending on where your process is running.

Apache Commons Lang has a class called StringUtils which contains many join functions.

Just use a if() { } else if () { } chain. Using a hash value is going to be a maintenance nightmare. switch is intended to be a low-level statement which would not be appropriate for string comparisons.

You might find it very useful to sample Redis keys and group them by type. Salvatore has written a tool called redis-sampler that issues about 10000 RANDOMKEY commands followed by a TYPE on retrieved keys. In a matter of seconds, or minutes, you should get a fairly accurate view of the distribution of key types.

I've written an extension (unfortunately not anywhere open-source because it's work related), that adds a bit of introspection of key names via regexs that give you an idea of what kinds of application keys (according to whatever naming structure you're using), are stored in Redis. Combined with the more general output of redis-sampler, this should give you an extremely good idea of what's going on.

Misconception Common misconception with column ordering is that, I should (or could) do the pushing and pulling on mobile devices, and that the desktop views should render in the natural order of the markup. This is wrong.

Reality Bootstrap is a mobile first framework. This means that the order of the columns in your HTML markup should represent the order in which you want them displayed on mobile devices. This mean that the pushing and pulling is done on the larger desktop views. not on mobile devices view..

Brandon Schmalz - Full Stack Web Developer Have a look at full description here

Building on gaoithe's answer, I attempted to make the memory units display in megabytes, and sorted by memory descending limited to 15 entries:

ps -e -orss=,args= |awk '{print $1 " " $2 }'| awk '{tot[$2]+=$1;count[$2]++} END {for (i in tot) {print tot[i],i,count[i]}}' | sort -n | tail -n 15 | sort -nr | awk '{ hr=$1/1024; printf("%13.2fM", hr); print "\t" $2 }'

       588.03M  /usr/sbin/apache2
       275.64M  /usr/sbin/mysqld
       138.23M  vim
        97.04M  -bash
        40.96M  ssh
        34.28M  tmux
        17.48M  /opt/digitalocean/bin/do-agent
        13.42M  /lib/systemd/systemd-journald
        10.68M  /lib/systemd/systemd
        10.62M  /usr/bin/redis-server
         8.75M  awk
         7.89M  sshd:
         4.63M  /usr/sbin/sshd
         4.56M  /lib/systemd/systemd-logind
         4.01M  /usr/sbin/rsyslogd

Here's an example alias to use it in a bash config file:

    alias topmem="ps -e -orss=,args= |awk '{print \$1 \" \" \$2 }'| awk '{tot[\$2]+=\$1;count[\$2]++} END {for (i in tot) {print tot[i],i,count[i]}}' | sort -n | tail -n 15 | sort -nr | awk '{ hr=\$1/1024; printf(\"%13.2fM\", hr); print \"\t\" \$2 }'"

Then you can just type topmem on the command line.

Slightly different approach:

MultiValueMap<String, String> headers = new LinkedMultiValueMap<String, String>();
headers.add("HeaderName", "value");
headers.add("Content-Type", "application/json");

RestTemplate restTemplate = new RestTemplate();
restTemplate.getMessageConverters().add(new MappingJackson2HttpMessageConverter());

HttpEntity<ObjectToPass> request = new HttpEntity<ObjectToPass>(objectToPass, headers);

restTemplate.postForObject(url, request, ClassWhateverYourControllerReturns.class);

You can use MATCH for instance.

1. Select the column from the first cell, for example cell A2 to cell A100 and insert a conditional formatting, using 'New Rule...' and the option to conditional format based on a formula.

2. In the entry box, put:

   =MATCH(A2, 'Sheet2'!A:A, 0)
   

3. Pick the desired formatting (change the font to red or fill the cell background, etc) and click OK.

MATCH takes the value A2 from your data table, looks into 'Sheet2'!A:A and if there's an exact match (that's why there's a 0 at the end), then it'll return the row number.

Note: Conditional formatting based on conditions from other sheets is available only on Excel 2010 onwards. If you're working on an earlier version, you might want to get the list of 'Don't check' in the same sheet.

EDIT: As per new information, you will have to use some reverse matching. Instead of the above formula, try:

=SUM(IFERROR(SEARCH('Sheet2'!$A$1:$A$44, A2),0))

h:commandButton must be enclosed in a h:form and has the two ways of navigation i.e. static by setting the action attribute and dynamic by setting the actionListener attribute hence it is more advanced as follows:

<h:form>
    <h:commandButton action="page.xhtml" value="cmdButton"/>
</h:form>

this code generates the follwing html:

<form id="j_idt7" name="j_idt7" method="post" action="/jsf/faces/index.xhtml" enctype="application/x-www-form-urlencoded">

whereas the h:button is simpler and just used for static or rule based navigation as follows

<h:button outcome="page.xhtml" value="button"/>

the generated html is

 <title>Facelet Title</title></head><body><input type="button" onclick="window.location.href='/jsf/faces/page.xhtml'; return false;" value="button" />

open etc folder in netbeans folder then edit the netbeans.conf with notepad and you will find a line like this :

Default location of JDK, can be overridden by using --jdkhome :
netbeans_jdkhome="G:\Program Files\Java\jdk1.6.0_13"

here you can set your jdk version.

Now I see what you are doing. You cannot send output to the screen then change the headers. If you are trying to create an XML file of map marker and download them to display, they should be in separate files.

Take this

<?php
require("database.php");
function parseToXML($htmlStr)
{
$xmlStr=str_replace('<','&lt;',$htmlStr);
$xmlStr=str_replace('>','&gt;',$xmlStr);
$xmlStr=str_replace('"','&quot;',$xmlStr);
$xmlStr=str_replace("'",'&#39;',$xmlStr);
$xmlStr=str_replace("&",'&amp;',$xmlStr);
return $xmlStr;
}
// Opens a connection to a MySQL server
$connection=mysql_connect (localhost, $username, $password);
if (!$connection) {
  die('Not connected : ' . mysql_error());
}
// Set the active MySQL database
$db_selected = mysql_select_db($database, $connection);
if (!$db_selected) {
  die ('Can\'t use db : ' . mysql_error());
}
// Select all the rows in the markers table
$query = "SELECT * FROM markers WHERE 1";
$result = mysql_query($query);
if (!$result) {
  die('Invalid query: ' . mysql_error());
}
header("Content-type: text/xml");
// Start XML file, echo parent node
echo '<markers>';
// Iterate through the rows, printing XML nodes for each
while ($row = @mysql_fetch_assoc($result)){
  // ADD TO XML DOCUMENT NODE
  echo '<marker ';
  echo 'name="' . parseToXML($row['name']) . '" ';
  echo 'address="' . parseToXML($row['address']) . '" ';
  echo 'lat="' . $row['lat'] . '" ';
  echo 'lng="' . $row['lng'] . '" ';
  echo 'type="' . $row['type'] . '" ';
  echo '/>';
}
// End XML file
echo '</markers>';
?>

and place it in phpsqlajax_genxml.php so your javascript can download the XML file. You are trying to do too many things in the same file.

"Case" can return single value only, but you can use complex type:

create type foo as (a int, b text);
select (case 1 when 1 then (1,'qq')::foo else (2,'ww')::foo end).*;

This should work for both strings and unicode objects in Python2, and both strings and bytes in Python3:

# python <3.0
def only_numerics(seq):
    return filter(type(seq).isdigit, seq)

# python =3.0
def only_numerics(seq):
    seq_type= type(seq)
    return seq_type().join(filter(seq_type.isdigit, seq))

I think the original answer is not exactly correct. append() changed both the slices and the underlying array even though the underlying array is changed but still shared by both of the slices.

As specified by the Go Doc:

A slice does not store any data, it just describes a section of an underlying array. (Link)

Slices are just wrapper values around arrays, meaning that they contain information about how they slice an underlying array which they use to store a set of data. Therefore, by default, a slice, when passed to another method, is actually passed by value, instead of reference/pointer even though they will still be using the same underlying array. Normally, arrays are also passed by value too, so I assume a slice points at an underlying array instead of store it as a value. Regarding your question, when you run passed your slice to the following function:

func Test(slice []int) {
    slice = append(slice, 100)
    fmt.Println(slice)
}

you actually passed a copy of your slice along with a pointer to the same underlying array.That means, the changes you did to the slice didn't affect the one in the main function. It is the slice itself which stores the information regarding how much of an array it slices and exposes to the public. Therefore, when you ran append(slice, 1000), while expanding the underlying array, you also changed slicing information of slice too, which was kept private in your Test() function.

However, if you have changed your code as follows, it might have worked:

func main() {
    for i := 0; i < 7; i++ {
        a[i] = i
    }

    Test(a)
    fmt.Println(a[:cap(a)])
}

The reason is that you expanded a by saying a[:cap(a)] over its changed underlying array, changed by Test() function. As specified here:

You can extend a slice's length by re-slicing it, provided it has sufficient capacity. (Link)

https://github.com/rackt/react-router/blob/bf89168acb30b6dc9b0244360bcbac5081cf6b38/examples/transitions/app.js#L50

or you can even try executing onClick this (more violent solution):

window.location.assign("/sample");

On Mac OS press: CMD+OPTION+J for console

I think the answer to this question pretty much sums up the problem with your question.

If what you want to do is find out whether a given host will accept TCP connections on port 80, you can do this:

$host = '193.33.186.70'; 
$port = 80; 
$waitTimeoutInSeconds = 1; 
if($fp = fsockopen($host,$port,$errCode,$errStr,$waitTimeoutInSeconds)){   
   // It worked 
} else {
   // It didn't work 
} 
fclose($fp);

For anything other than TCP it will be more difficult (although since you specify 80, I guess you are looking for an active HTTP server, so TCP is what you want). TCP is sequenced and acknowledged, so you will implicitly receive a returned packet when a connection is successfully made. Most other transport protocols (commonly UDP, but others as well) do not behave in this manner, and datagrams will not be acknowledged unless the overlayed Application Layer protocol implements it.

The fact that you are asking this question in this manner tells me you have a fundamental gap in your knowledge on Transport Layer protocols. You should read up on ICMP and TCP, as well as the OSI Model.

Also, here's a slightly cleaner version to ping to hosts.

// Function to check response time
function pingDomain($domain){
    $starttime = microtime(true);
    $file      = fsockopen ($domain, 80, $errno, $errstr, 10);
    $stoptime  = microtime(true);
    $status    = 0;

    if (!$file) $status = -1;  // Site is down
    else {
        fclose($file);
        $status = ($stoptime - $starttime) * 1000;
        $status = floor($status);
    }
    return $status;
}

You can change the name of the column, therefore instead of "COUNT(*)" you would have something meaningful. You will have to update your "RowCount.sql" script for that.

For example:

SQL> select count(*) as RecordCountFromTableOne from TableOne;

Will be displayed as:

RecordCountFromTableOne
-----------------------
           0

If you want to have space in the title, you need to enclose it in double quotes

SQL> select count(*) as "Record Count From Table One" from TableOne;

Will be displayed as:

Record Count From Table One
---------------------------
            0

I also ran into this error when I was using Dapper and forgot to input a parameterized value.

To fix I had to ensure that the object passed in as a parameter had properties matching the parameterised values in the SQL string.

I’ve found a solution. I had to clear fragment’s parent from views before destroying and I’ve used the next peace of code for this:

in Java

public void onDestroyView() {
        if (rootView != null){
            ViewGroup viewGroup = (ViewGroup)rootView.getParent();
            if (viewGroup != null){
                viewGroup.removeAllViews();
            }
        }
        super.onDestroyView();
    }

in Kotlin

override fun onDestroyView() {
    if (rootView != null) {
        val viewGroup = rootView.parent as ViewGroup?
        viewGroup?.removeAllViews();
    }
    super.onDestroyView()
}

create directory in /res/anim and create bottom_to_original.xml

<?xml version="1.0" encoding="utf-8"?>
<set xmlns:android="http://schemas.android.com/apk/res/android">
    <translate
        android:duration="1500"
        android:fromYDelta="100%"
        android:toYDelta="1%" />
</set>

JAVA:

    LinearLayout ll = findViewById(R.id.ll);

    Animation animation;
    animation = AnimationUtils.loadAnimation(getApplicationContext(),
            R.anim.sample_animation);
    ll .setAnimation(animation);

import os
for root, dirs, files in os.walk(top, topdown=False):
    for name in dirs:
        print os.path.join(root, name)

Walk is a good built-in for what you are doing

Add the 'columns' parameter:

frame = pd.DataFrame({
        'one thing':[1,2,3,4],
        'second thing':[0.1,0.2,1,2],
        'other thing':['a','e','i','o']},
        columns=['one thing', 'second thing', 'other thing']
)

For Swift use the below code:

 func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: NSDictionary?) -> Bool {
    self.window = UIWindow(frame: UIScreen.mainScreen().bounds)
    self.window!.backgroundColor = UIColor.whiteColor()

    // Create a nav/vc pair using the custom ViewController class

    let nav = UINavigationController()
    let vc = NextViewController(nibName: "NextViewController", bundle: nil)

    // Push the vc onto the nav
    nav.pushViewController(vc, animated: false)

    // Set the window’s root view controller
    self.window!.rootViewController = nav

    // Present the window
    self.window!.makeKeyAndVisible()
    return true

}

ViewController:

 @IBAction func Next(sender : AnyObject)
{
    let nextViewController = DurationDel(nibName: "DurationDel", bundle: nil)

    self.navigationController.pushViewController(nextViewController, animated: true)
}

More simple:

return (byte[])System.ComponentModel.TypeDescriptor.GetConverter(pImagen).ConvertTo(pImagen, typeof(byte[]))

Support for single character marker labels was added to Google Maps in version 3.21 (Aug 2015). See the new marker label API.

You can now create your label marker like this:

var marker = new google.maps.Marker({
  position: new google.maps.LatLng(result.latitude, result.longitude), 
  icon: markerIcon,
  label: {
    text: 'A'
  }
});

If you would like to see the 1 character restriction removed, please vote for this issue.

Update October 2016:

This issue was fixed and as of version 3.26.10, Google Maps natively supports multiple character labels in combination with custom icons using MarkerLabels.

You don't have to bind parameters if you use query builder or eloquent ORM. However, if you use DB::raw(), ensure that you binding the parameters.

Try the following:

$array = array(1,2,3);       $query = DB::table('offers');             $query->select('id', 'business_id', 'address_id', 'title', 'details', 'value', 'total_available', 'start_date', 'end_date', 'terms', 'type', 'coupon_code', 'is_barcode_available', 'is_exclusive', 'userinformations_id', 'is_used');             $query->leftJoin('user_offer_collection', function ($join) use ($array)             {                 $join->on('user_offer_collection.offers_id', '=', 'offers.id')                       ->whereIn('user_offer_collection.user_id', $array);             });       $query->get(); 

check out System.Enum.Parse:

enum Colors {Red, Green, Blue}

// your code:
Colors color = (Colors)System.Enum.Parse(typeof(Colors), "Green");

Linus is spot on in the approach, but a few properties are off. It looks like 'AgencyContractId' is your Primary Key, which is unrelated to the output you want to give the user. I think this is what you want (assuming you change your ViewModel to match the data you say you want in your view).

var agencyContracts = _agencyContractsRepository.AgencyContracts
    .GroupBy(ac => new
                   {
                       ac.AgencyID,
                       ac.VendorID,
                       ac.RegionID
                   })
    .Select(ac => new AgencyContractViewModel
                   {
                       AgencyId = ac.Key.AgencyID,
                       VendorId = ac.Key.VendorID,
                       RegionId = ac.Key.RegionID,
                       Total = ac.Sum(acs => acs.Amount) + ac.Sum(acs => acs.Fee)
                   });

For example you might decide a LinkedList is the best choice for your application, but then later decide ArrayList might be a better choice for performance reason.

Use:

List list = new ArrayList(100); // will be better also to set the initial capacity of a collection 

Instead of:

ArrayList list = new ArrayList();

For reference:

^{(posted mostly for Collection diagram)}

In CurrentGame component you need to change initial state because you are trying use loop for participants but this property is undefined that's why you get error.,

getInitialState: function(){
    return {
       data: {
          participants: [] 
       }
    };
},

also, as player in .map is Object you should get properties from it

this.props.data.participants.map(function(player) {
   return <li key={player.championId}>{player.summonerName}</li>
   // -------------------^^^^^^^^^^^---------^^^^^^^^^^^^^^
})

Example

To someone who really understands how JS works this question might seem off, however most people who use JS do not have such a deep level of insight (and don't necessarily need it) and to them this is a fairly confusing point, I will try to answer from that perspective.

JS is synchronous in the way its code is executed. each line only runs after the line before it has completed and if that line calls a function after that is complete etc...

The main point of confusion arises from the fact that your browser is able to tell JS to execute more code at anytime (similar to how you can execute more JS code on a page from the console). As an example JS has Callback functions who's purpose is to allow JS to BEHAVE asynchronously so further parts of JS can run while waiting for a JS function that has been executed (I.E. a GET call) to return back an answer, JS will continue to run until the browser has an answer at that point the event loop (browser) will execute the JS code that calls the callback function.

Since the event loop (browser) can input more JS to be executed at any point in that sense JS is asynchronous (the primary things that will cause a browser to input JS code are timeouts, callbacks and events)

I hope this is clear enough to be helpful to somebody.

int b;
double a;
a=3669.0;
b=a;
printf("b=%d",b);

this code gives the output as b=3669 only you check it clearly.

For completeness sake, this is the method that ended up working for me. It was a combination of @Anthony & @iAn's methods.

      NSIndexPath *visibleIndexPath = [self.collectionView indexPathForItemAtPoint:visiblePoint];
      NSLog(@"%@",visibleIndexPath);
}

It will not be ok until you add your user to the group www by the following commands:

sudo usermod -a -G www <USER>

This solves the permission problem.

Set the default path by adding this:

local_root=/var/www/html

Here is what worked in the end for me.

You can use Named Sections.

_Layout.cshtml

<head>
    <script type="text/javascript" src="@Url.Content("/Scripts/jquery-1.6.2.min.js")"></script>
    @RenderSection("JavaScript", required: false)
</head>

_SomeView.cshtml

@section JavaScript
{
   <script type="text/javascript" src="@Url.Content("/Scripts/SomeScript.js")"></script>
   <script type="text/javascript" src="@Url.Content("/Scripts/AnotherScript.js")"></script>
}

A trivial approach would be to replace

<[^>]*>

with nothing. But depending on how ill-structured your input is that may well fail.

You forgot to add std:: namespace prefix to vector class name.

The only way that worked for me was with the JRockit JVM. I have MyEclipse 8.6.

The JVM's heap stores all the objects generated by a running Java program. Java uses the new operator to create objects, and memory for new objects is allocated on the heap at run time. Garbage collection is the mechanism of automatically freeing up the memory contained by the objects that are no longer referenced by the program.

You can easily call a method from any Fragment inside your Activity by doing a cast like this:

Java

((MainActivity)getActivity()).startChronometer();

Kotlin

(activity as MainActivity).startChronometer()

Just remember to make sure this Fragment's activity is in fact MainActivity before you do it.

Hope this helps!

1. Best answer based on my assessment:

The answer by @Adisak is the best answer here based on my assessment. Note that this answer is in part the best because it is also the _most well-backed-up with real code examples, in addition to using sound and well-thought-out logic._

2. My own words (agreeing with the best answer):

1. For pass-by-value there is no benefit to adding const. All it does is:
   1. limit the implementer to have to make a copy every time they want to change an input param in the source code (which change would have no side effects anyway since what's passed in is already a copy since it's pass-by-value). And frequently, changing an input param which is passed by value is used to implement the function, so adding const everywhere can hinder this.
   2. and adding const unnecessarily clutters the code with consts everywhere, drawing attention away from the consts that are truly necessary to have safe code.
2. When dealing with pointers or references, however, const is critically important when needed, and must be used, as it prevents undesired side effects with persistent changes outside the function, and therefore every single pointer or reference must use const when the param is an input only, not an output. Using const only on parameters passed by reference or pointer has the additional benefit of making it really obvious which parameters are pointers or references. It's one more thing to stick out and say "Watch out! Any param with const next to it is a reference or pointer!".
3. What I've described above has frequently been the consensus achieved in professional software organizations I have worked in, and has been considered best practice. Sometimes even, the rule has been strict: "don't ever use const on parameters which are passed by value, but always use it on parameters passed by reference or pointer if they are inputs only."

3. Google's words (agreeing with me and the best answer):

(From the "Google C++ Style Guide")

For a function parameter passed by value, const has no effect on the caller, thus is not recommended in function declarations. See TotW #109.

Using const on local variables is neither encouraged nor discouraged.

Source: the "Use of const" section of the Google C++ Style Guide: https://google.github.io/styleguide/cppguide.html#Use_of_const. This is actually a really valuable section, so read the whole section.

Note that "TotW #109" stands for "Tip of the Week #109: Meaningful const in Function Declarations", and is also a useful read. It is more informative and less prescriptive on what to do, and based on context came before the Google C++ Style Guide rule on const quoted just above, but as a result of the clarity it provided, the const rule quoted just above was added to the Google C++ Style Guide.

Also note that even though I'm quoting the Google C++ Style Guide here in defense of my position, it does NOT mean I always follow the guide or always recommend following the guide. Some of the things they recommend are just plain weird, such as their kDaysInAWeek-style naming convention for "Constant Names". However, it is still nonetheless useful and relevant to point out when one of the world's most successful and influential technical and software companies uses the same justification as I and others like @Adisak do to back up our viewpoints on this matter.

4. Clang's linter, clang-tidy, has some options for this:

A. It's also worth noting that Clang's linter, clang-tidy, has an option, readability-avoid-const-params-in-decls, described here, to support enforcing in a code base not using const for pass-by-value function parameters:

Checks whether a function declaration has parameters that are top level const.

const values in declarations do not affect the signature of a function, so they should not be put there.

Examples:

void f(const string);   // Bad: const is top level.
void f(const string&);  // Good: const is not top level.

And here are two more examples I'm adding myself for completeness and clarity:

void f(char * const c_string);   // Bad: const is top level. [This makes the _pointer itself_, NOT what it points to, const]
void f(const char * c_string);   // Good: const is not top level. [This makes what is being _pointed to_ const]

B. It also has this option: readability-const-return-type - https://clang.llvm.org/extra/clang-tidy/checks/readability-const-return-type.html

5. My pragmatic approach to how I'd word a style guide on the matter:

I'd simply copy and paste this into my style guide:

[COPY/PASTE START]

1. Always use const on function parameters passed by reference or pointer when their contents (what they point to) are intended NOT to be changed. This way, it becomes obvious when a variable passed by reference or pointer IS expected to be changed, because it will lack const. In this use case const prevents accidental side effects outside the function.
2. It is not recommended to use const on function parameters passed by value, because const has no effect on the caller: even if the variable is changed in the function there will be no side effects outside the function. See the following resources for additional justification and insight:
   1. "Google C++ Style Guide" "Use of const" section
   2. "Tip of the Week #109: Meaningful const in Function Declarations"
   3. Adisak's Stack Overflow answer on "Use of 'const' for function parameters"
3. "Never use top-level const [ie: const on parameters passed by value] on function parameters in declarations that are not definitions (and be careful not to copy/paste a meaningless const). It is meaningless and ignored by the compiler, it is visual noise, and it could mislead readers" (https://abseil.io/tips/109, emphasis added).
4. The only const qualifiers that have an effect on compilation are those placed in the function definition, NOT those in a forward declaration of the function, such as in a function (method) declaration in a header file.
5. Never use top-level const [ie: const on variables passed by value] on values returned by a function.
6. Using const on pointers or references returned by a function is up to the implementer, as it is sometimes useful.
7. TODO: enforce some of the above with the following clang-tidy options:
8. https://clang.llvm.org/extra/clang-tidy/checks/readability-avoid-const-params-in-decls.html
9. https://clang.llvm.org/extra/clang-tidy/checks/readability-const-return-type.html

Here are some code examples to demonstrate the const rules described above:

const Parameter Examples:
(some are borrowed from here)

void f(const std::string);   // Bad: const is top level.
void f(const std::string&);  // Good: const is not top level.

void f(char * const c_string);   // Bad: const is top level. [This makes the _pointer itself_, NOT what it points to, const]
void f(const char * c_string);   // Good: const is not top level. [This makes what is being _pointed to_ const]

const Return Type Examples:
(some are borrowed from here)

// BAD--do not do this:
const int foo();
const Clazz foo();
Clazz *const foo();

// OK--up to the implementer:
const int* foo();
const int& foo();
const Clazz* foo();

[COPY/PASTE END]

If you want to create a file and write and append data to it many times, then use the below code, it will create file if not exits and will append data if it exists.

 SimpleDateFormat formatter = new SimpleDateFormat("yyyy_MM_dd");
        Date now = new Date();
        String fileName = formatter.format(now) + ".txt";//like 2016_01_12.txt


         try
            {
                File root = new File(Environment.getExternalStorageDirectory()+File.separator+"Music_Folder", "Report Files");
                //File root = new File(Environment.getExternalStorageDirectory(), "Notes");
                if (!root.exists()) 
                {
                    root.mkdirs();
                }
                File gpxfile = new File(root, fileName);


                FileWriter writer = new FileWriter(gpxfile,true);
                writer.append(sBody+"\n\n");
                writer.flush();
                writer.close();
                Toast.makeText(this, "Data has been written to Report File", Toast.LENGTH_SHORT).show();
            }
            catch(IOException e)
            {
                 e.printStackTrace();

            }

Altough the question is for HTML, I would also additionally like to give info about how to auto-format your Javascript code for Sublime Text 2;

You can select all your code(ctrl + A) and use the in-app functionality, reindent(Edit -> Line -> Reindent) or you can use JsFormat formatting plugin for Sublime Text 2 if you would like to have more customizable settings on how to format your code to addition to the Sublime Text's default tab/indent settings.

https://github.com/jdc0589/JsFormat

You can easily install JsFormat with using Package Control (Preferences -> Package Control) Open package control then type install, hit enter. Then type js format and hit enter, you're done. (The package controller will show the status of the installation with success and errors on the bottom left bar of Sublime)

Add the following line to your key bindings (Preferences -> Key Bindings User)

{ "keys": ["ctrl+alt+2"], "command": "js_format"}

I'm using ctrl + alt + 2, you can change this shortcut key whatever you want to. So far, JsFormat is a good plugin, worth to try it!

Hope this will help someone.

You can think of the HEAD as the "current branch". When you switch branches with git checkout, the HEAD revision changes to point to the tip of the new branch.

You can see what HEAD points to by doing:

cat .git/HEAD

In my case, the output is:

$ cat .git/HEAD
ref: refs/heads/master

It is possible for HEAD to refer to a specific revision that is not associated with a branch name. This situation is called a detached HEAD.

The STAThreadAttribute marks a thread to use the Single-Threaded COM Apartment if COM is needed. By default, .NET won't initialize COM at all. It's only when COM is needed, like when a COM object or COM Control is created or when drag 'n' drop is needed, that COM is initialized. When that happens, .NET calls the underlying CoInitializeEx function, which takes a flag indicating whether to join the thread to a multi-threaded or single-threaded apartment.

Read more info here (Archived, June 2009)

and

Why is STAThread required?

If you only have one typeface you would like to add, and want less code to write, you can create a dedicated TextView for your specific font. See code below.

package com.yourpackage;
import android.content.Context;
import android.graphics.Typeface;
import android.util.AttributeSet;
import android.widget.TextView;

public class FontTextView extends TextView {
    public static Typeface FONT_NAME;


    public FontTextView(Context context) {
        super(context);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/FontName.otf");
        this.setTypeface(FONT_NAME);
    }
    public FontTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/FontName.otf");
        this.setTypeface(FONT_NAME);
    }
    public FontTextView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
        if(FONT_NAME == null) FONT_NAME = Typeface.createFromAsset(context.getAssets(), "fonts/FontName.otf");
        this.setTypeface(FONT_NAME);
    }
}

In main.xml, you can now add your textView like this:

<com.yourpackage.FontTextView
    android:id="@+id/tvTimer"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:text="" />

ul li + li:before
{
    content:url(imgs/separator.gif);
}

Your error is in UpdaterServiceManager in onCreate and showNotification method.

You are trying to show notification from Service using Activity Context. Whereas Every Service has its own Context, just use the that. You don't need to pass a Service an Activity's Context.I don't see why you need a specific Activity's Context to show Notification.

Put your createNotification method in UpdateServiceManager.class. And remove CreateNotificationActivity not from Service.

You cannot display an application window/dialog through a Context that is not an Activity. Try passing a valid activity reference

Use the built-in localized formats

If this is for showing a time of day to a user, then in at least 19 out of 20 you don’t need to care about kk, HH nor hh. I suggest that you use something like this:

    DateTimeFormatter defaultTimeFormatter
            = DateTimeFormatter.ofLocalizedTime(FormatStyle.SHORT);
    System.out.format("%s: %s%n",
            Locale.getDefault(), LocalTime.MIN.format(defaultTimeFormatter));

The point is that it gives different output in different default locales. For example:

en_SS: 12:00 AM
fr_BL: 00:00
ps_AF: 0:00
es_CO: 12:00 a.m.

The localized formats have been designed to conform with the expectations of different cultures. So they generally give the user a better experience and they save you of writing a format pattern string, which is always error-prone.

I furthermore suggest that you don’t use SimpleDateFormat. That class is notoriously troublesome and fortunately long outdated. Instead I use java.time, the modern Java date and time API. It is so much nicer to work with.

Four pattern letters for hour: H, h, k and K

Of course if you need to parse a string with a specified format, and also if you have a very specific formatting requirement, it’s good to use a format pattern string. There are actually four different pattern letters to choose from for hour (quoted from the documentation):

  Symbol  Meaning                     Presentation      Examples
  ------  -------                     ------------      -------
   h       clock-hour-of-am-pm (1-12)  number            12
   K       hour-of-am-pm (0-11)        number            0
   k       clock-hour-of-day (1-24)    number            24
   H       hour-of-day (0-23)          number            0

In practice H and h are used. As far as I know k and K are not (they may just have been included for the sake of completeness). But let’s just see them all in action:

    DateTimeFormatter timeFormatter
            = DateTimeFormatter.ofPattern("hh:mm a  HH:mm  kk:mm  KK:mm a", Locale.ENGLISH);
    System.out.println(LocalTime.of(0, 0).format(timeFormatter));
    System.out.println(LocalTime.of(1, 15).format(timeFormatter));
    System.out.println(LocalTime.of(11, 25).format(timeFormatter));
    System.out.println(LocalTime.of(12, 35).format(timeFormatter));
    System.out.println(LocalTime.of(13, 40).format(timeFormatter));

12:00 AM  00:00  24:00  00:00 AM
01:15 AM  01:15  01:15  01:15 AM
11:25 AM  11:25  11:25  11:25 AM
12:35 PM  12:35  12:35  00:35 PM
01:40 PM  13:40  13:40  01:40 PM

If you don’t want the leading zero, just specify one pattern letter, that is h instead of hh or H instead of HH. It will still accept two digits when parsing, and if a number to be printed is greater than 9, two digits will still be printed.

For your purposes, if all the items are stored as str and you just use sorted as you are using and then check for the first element and replace it with '0'

>>> l1 = ['88','NaN','67','89','81']
>>> n = sorted(l1,reverse=True)
['NaN', '89', '88', '81', '67']
>>> import math
>>> if math.isnan(float(n[0])):
...     n[0] = '0'
... 
>>> n
['0', '89', '88', '81', '67']

Check google-services.json file in app folder of your Android project. Generate a new one from Firebase console if you are unsure. I got this error in two cases.

1. I used a test Firebase project with test application (that contained right google-services.json file). Then I tried to send push notification to another application and got this error ('"error": "MismatchSenderId"'). I understood that the second application was bound to another Firebase project with different google-services.json. Because server keys are different, the request should be rewritten.

2. I changed google-services.json in the application, because I wanted to replace test Firebase project with an actual. I generated right google-services.json file, changed request, but kept receiving this error. On the next day it fixed itself. I suspect Firebase doesn't update synchronously.

To get a server key for the request, open https://console.firebase.google.com and select an appropriate project.

Then paste it in the request.

I kept having this problem whenever I tried to start an app pool more than once. Rather than rebooting, I simply run the Application Information Service. (Note: This service is set to run manually on my system, which may be the reason for the problem.) From its description, it seems obvious that it is somehow involved:

Facilitates the running of interactive applications with additional administrative privileges. If this service is stopped, users will be unable to launch applications with the additional administrative privileges they may require to perform desired user tasks.

Presumably, IIS manager (as well as most other processes running as an administrator) does not maintain admin privileges throughout the life of the process, but instead request admin rights from the Application Information service on a case-by-case basis.

"Why do i get that error?" - probably, you don't have "using System.Collections;" at the top of the file - only "using System.Collections.Generic;" - however, generics are probably safer - see below:

static bool ArraysEqual<T>(T[] a1, T[] a2)
{
    if (ReferenceEquals(a1,a2))
        return true;

    if (a1 == null || a2 == null)
        return false;

    if (a1.Length != a2.Length)
        return false;

    EqualityComparer<T> comparer = EqualityComparer<T>.Default;
    for (int i = 0; i < a1.Length; i++)
    {
        if (!comparer.Equals(a1[i], a2[i])) return false;
    }
    return true;
}

simpler is better - make sense?

in this case just members[0] = 0 works. don't make a simple question so complicated.

I recommend you to use a HTML parser. Just find the fastest one.

Parsing HTML is not as easy as it may seem.

Browsers parse invalid UTF-8 sequences, in UTF-8 HTML documents, just putting the "?" symbol. So once the invalid UTF-8 sequence in the HTML gets parsed the resulting text is a valid string.

Even inside attribute values you have to decode HTML entities like amp

Here is a great question that sums up why you can not reliably parse HTML with a regular expression: RegEx match open tags except XHTML self-contained tags

Especially if you use a copy-on-write filesystem like BTRFS or ZFS, rsync is much better.

I use BTRFS, and I have this in my ~/.bashrc:

alias cp="rsync -ah --inplace --no-whole-file --info=progress2"

The important flag here for CoW FSs like BTRFS is --inplace because it only copies the changed part of the files, doesn't create new for small changes between files inodes, etc. See this.

I have today similar problem. But weirder.

• dig - works on default and on all other DNS's dig pl.archive.ubuntu.com, dig @127.0.1.1 pl.archive.ubuntu.com
• curl - doesn't work! but for some addresses it does. WEIRD! Same in Ruby, APT and many more.

Revelation

Eventually I used strace on curl and found that it was connection to nscd deamon.

connect(4, {sa_family=AF_LOCAL, sun_path="/var/run/nscd/socket"}, 110) = 0

Solution

I've restarted the nscd service (Name Service Cache Daemon) and it helped to solve this issue!

systemctl restart nscd.service

I wouldn't recommend the HAVING keyword for newbies, it is essentially for legacy purposes.

I am not clear on what is the key for this table (is it fully normalized, I wonder?), consequently I find it difficult to follow your specification:

I would like to find all records for all users that have more than one payment per day with the same account number... Additionally, there should be a filter than only counts the records whose ZIP code is different.

So I've taken a literal interpretation.

The following is more verbose but could be easier to understand and therefore maintain (I've used a CTE for the table PAYMENT_TALLIES but it could be a VIEW:

WITH PAYMENT_TALLIES (user_id, zip, tally)
     AS
     (
      SELECT user_id, zip, COUNT(*) AS tally
        FROM PAYMENT
       GROUP 
          BY user_id, zip
     )
SELECT DISTINCT *
  FROM PAYMENT AS P
 WHERE EXISTS (
               SELECT * 
                 FROM PAYMENT_TALLIES AS PT
                WHERE P.user_id = PT.user_id
                      AND PT.tally > 1
              );

If you have python various versions of python installed,you can launch any of them using pythonx.x.x where x.x.x represents your versions.

json.dumps() is much more than just making a string out of a Python object, it would always produce a valid JSON string (assuming everything inside the object is serializable) following the Type Conversion Table.

For instance, if one of the values is None, the str() would produce an invalid JSON which cannot be loaded:

>>> data = {'jsonKey': None}
>>> str(data)
"{'jsonKey': None}"
>>> json.loads(str(data))
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/__init__.py", line 338, in loads
    return _default_decoder.decode(s)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 366, in decode
    obj, end = self.raw_decode(s, idx=_w(s, 0).end())
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/json/decoder.py", line 382, in raw_decode
    obj, end = self.scan_once(s, idx)
ValueError: Expecting property name: line 1 column 2 (char 1)

But the dumps() would convert None into null making a valid JSON string that can be loaded:

>>> import json
>>> data = {'jsonKey': None}
>>> json.dumps(data)
'{"jsonKey": null}'
>>> json.loads(json.dumps(data))
{u'jsonKey': None}

This is likely already out there, but I was playing with renaming fields while searching out a solution and tried this on a whim. Worked for my purposes.

Table1$FieldNewName <- Table1$FieldOldName
Table1$FieldOldName <- NULL

Edit begins here....

This works as well.

df <- rename(df, c("oldColName" = "newColName"))

The problem is that you can't use a list as the key in a dict, since dict keys need to be immutable. Use a tuple instead.

This is a list:

[x, y]

This is a tuple:

(x, y)

Note that in most cases, the ( and ) are optional, since , is what actually defines a tuple (as long as it's not surrounded by [] or {}, or used as a function argument).

You might find the section on tuples in the Python tutorial useful:

Though tuples may seem similar to lists, they are often used in different situations and for different purposes. Tuples are immutable, and usually contain an heterogeneous sequence of elements that are accessed via unpacking (see later in this section) or indexing (or even by attribute in the case of namedtuples). Lists are mutable, and their elements are usually homogeneous and are accessed by iterating over the list.

And in the section on dictionaries:

Unlike sequences, which are indexed by a range of numbers, dictionaries are indexed by keys, which can be any immutable type; strings and numbers can always be keys. Tuples can be used as keys if they contain only strings, numbers, or tuples; if a tuple contains any mutable object either directly or indirectly, it cannot be used as a key. You can’t use lists as keys, since lists can be modified in place using index assignments, slice assignments, or methods like append() and extend().

In case you're wondering what the error message means, it's complaining because there's no built-in hash function for lists (by design), and dictionaries are implemented as hash tables.

There is a utility called : mongodump On the mongo command line you can type :

>./mongodump

The above will create a dump of all the databases on your localhost. To make dump of a single collection use:

./mongodump --db blog --collection posts

Have a look at : mongodump

These functions, based on the above, seem to work well for getting characters from the keyboard (blocking and non-blocking):

import termios, fcntl, sys, os

def get_char_keyboard():
  fd = sys.stdin.fileno()

  oldterm = termios.tcgetattr(fd)
  newattr = termios.tcgetattr(fd)
  newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
  termios.tcsetattr(fd, termios.TCSANOW, newattr)

  c = None
  try:
    c = sys.stdin.read(1)
  except IOError: pass

  termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)

  return c

def get_char_keyboard_nonblock():
  fd = sys.stdin.fileno()

  oldterm = termios.tcgetattr(fd)
  newattr = termios.tcgetattr(fd)
  newattr[3] = newattr[3] & ~termios.ICANON & ~termios.ECHO
  termios.tcsetattr(fd, termios.TCSANOW, newattr)

  oldflags = fcntl.fcntl(fd, fcntl.F_GETFL)
  fcntl.fcntl(fd, fcntl.F_SETFL, oldflags | os.O_NONBLOCK)

  c = None

  try:
    c = sys.stdin.read(1)
  except IOError: pass

  termios.tcsetattr(fd, termios.TCSAFLUSH, oldterm)
  fcntl.fcntl(fd, fcntl.F_SETFL, oldflags)

  return c

This message from git means that you have made three commits in your local repo, and have not published them to the master repository. The command to run for that is git push {local branch name} {remote branch name}.

The command git pull (and git pull --rebase) are for the other situation when there are commit on the remote repo that you don't have in your local repo. The --rebase option means that git will move your local commit aside, synchronise with the remote repo, and then try to apply your three commit from the new state. It may fail if there is conflict, but then you'll be prompted to resolve them. You can also abort the rebase if you don't know how to resolve the conflicts by using git rebase --abort and you'll get back to the state before running git pull --rebase.

My last adventure with MSDTC and this error today turned out to be a DNS issue. You're on the right track asking if the machines are on the same domain, EBarr. Terrific list for this issue, by the way!

My situation: I needed a server in a child domain to be able to run distributed transactions against a server in the parent domain through a firewall. I've used linked servers quite a bit over the years, so I had all the usual settings in SQL for a linked server and in MSDTC that Ian documented so nicely above. I set up MSDTC with a range of TCP ports (5000-5200) to use on both servers, and arranged for a firewall hole between the boxes for ports 1433 and 5000-5200. That should have worked. The linked server tested OK and I could query the remote SQL server via the linked server nicely, but I couldn't get it to allow a distributed transaction. I could even see a connection on the QA server from the DEV server, but something wasn't making the trip back.

I could PING the DEV server from QA using a FQDN like: PING DEVSQL.dev.domain.com

I could not PING the DEV server with just the machine name: PING DEVSQL

The DEVSQL server was supposed to be a member of both domains, but the name wasn't resolving in the parent domain's DNS... something had happened to the machine account for DEVSQL in the parent domain. Once we added DEVSQL to the DNS for the parent domain, and "PING DEVSQL" worked from the remote QA server, this issue was resolved for us.

I hope this helps!

You have to check if the argument is undefined:

function func(a, b) {
    if (a === undefined) a = "default value";
    if (b === undefined) b = "default value";
}

Also note that this question has been answered before.

The alternative would be to use ServletContext.getResource() which returns a URI. This URI may be a 'file:' URL, but there's no guarantee for that.

You don't need it to be a file:... URL. You just need it to be a URL that your JVM can read--and it will be.

I found a bug in MySQL 5.1.72 when using the nested if() functions .... the value of column variables (e.g. qty_1) is blank inside the second if(), rendering it useless. Use the following construct instead:

case 
  when qty_1<='23' then price
  when '23'>qty_1 && qty_2<='23' then price_2
  when '23'>qty_2 && qty_3<='23' then price_3
  when '23'>qty_3 then price_4
  else 1
end

Another user mentioned this in slight detail but I missed it until I came back here about 3 times over 2 days -

There is a section titled EventListener breakpoints that contains a list of other breakpoints that can be set. It happens that I accidentally enabled one of them on DOM Mutation that was letting me know whenever anything to the DOM was overridden. Unfortunately this led to me disabling a bunch of plug-ins and add-ons before I realized it was just my machine. Hope this helps someone else.

If you're using .NET 4, simply use File.ReadLines which does it all for you. I suspect it's much the same as yours, except it may also use FileOptions.SequentialScan and a larger buffer (128 seems very small).

I've always considered throwing checked exceptions in the constructor to be bad practice, or at least something that should be avoided.

The reason for this is that you cannot do this :

private SomeObject foo = new SomeObject();

Instead you must do this :

private SomeObject foo;
public MyObject() {
    try {
        foo = new SomeObject()
    } Catch(PointlessCheckedException e) {
       throw new RuntimeException("ahhg",e);
    }
}

At the point when I'm constructing SomeObject I know what it's parameters are so why should I be expected to wrap it in a try catch? Ahh you say but if I'm constructing an object from dynamic parameters I don't know if they're valid or not. Well, you could... validate the parameters before passing them to the constructor. That would be good practice. And if all you're concerned about is whether the parameters are valid then you can use IllegalArgumentException.

So instead of throwing checked exceptions just do

public SomeObject(final String param) {
    if (param==null) throw new NullPointerException("please stop");
    if (param.length()==0) throw new IllegalArgumentException("no really, please stop");
}

Of course there are cases where it might just be reasonable to throw a checked exception

public SomeObject() {
    if (todayIsWednesday) throw new YouKnowYouCannotDoThisOnAWednesday();
}

But how often is that likely?

As mentioned in other answers, you'll always get the QuotaExceededError in Safari Private Browser Mode on both iOS and OS X when localStorage.setItem (or sessionStorage.setItem) is called.

One solution is to do a try/catch or Modernizr check in each instance of using setItem.

However if you want a shim that simply globally stops this error being thrown, to prevent the rest of your JavaScript from breaking, you can use this:

https://gist.github.com/philfreo/68ea3cd980d72383c951

// Safari, in Private Browsing Mode, looks like it supports localStorage but all calls to setItem
// throw QuotaExceededError. We're going to detect this and just silently drop any calls to setItem
// to avoid the entire page breaking, without having to do a check at each usage of Storage.
if (typeof localStorage === 'object') {
    try {
        localStorage.setItem('localStorage', 1);
        localStorage.removeItem('localStorage');
    } catch (e) {
        Storage.prototype._setItem = Storage.prototype.setItem;
        Storage.prototype.setItem = function() {};
        alert('Your web browser does not support storing settings locally. In Safari, the most common cause of this is using "Private Browsing Mode". Some settings may not save or some features may not work properly for you.');
    }
}

Now, after I was pointed in the right direction, here's my complete solution:

This is the middleware class which is executed on every incoming request and checks if the request has the correct credentials. If no credentials are present or if they are wrong, the service responds with a 401 Unauthorized error immediately.

public class AuthenticationMiddleware
{
    private readonly RequestDelegate _next;

    public AuthenticationMiddleware(RequestDelegate next)
    {
        _next = next;
    }

    public async Task Invoke(HttpContext context)
    {
        string authHeader = context.Request.Headers["Authorization"];
        if (authHeader != null && authHeader.StartsWith("Basic"))
        {
            //Extract credentials
            string encodedUsernamePassword = authHeader.Substring("Basic ".Length).Trim();
            Encoding encoding = Encoding.GetEncoding("iso-8859-1");
            string usernamePassword = encoding.GetString(Convert.FromBase64String(encodedUsernamePassword));

            int seperatorIndex = usernamePassword.IndexOf(':');

            var username = usernamePassword.Substring(0, seperatorIndex);
            var password = usernamePassword.Substring(seperatorIndex + 1);

            if(username == "test" && password == "test" )
            {
                await _next.Invoke(context);
            }
            else
            {
                context.Response.StatusCode = 401; //Unauthorized
                return;
            }
        }
        else
        {
            // no authorization header
            context.Response.StatusCode = 401; //Unauthorized
            return;
        }
    }
}

The middleware extension needs to be called in the Configure method of the service Startup class

public void Configure(IApplicationBuilder app, IHostingEnvironment env, ILoggerFactory loggerFactory)
{
    loggerFactory.AddConsole(Configuration.GetSection("Logging"));
    loggerFactory.AddDebug();

    app.UseMiddleware<AuthenticationMiddleware>();

    app.UseMvc();
}

And that's all! :)

A very good resource for middleware in .Net Core and authentication can be found here: https://www.exceptionnotfound.net/writing-custom-middleware-in-asp-net-core-1-0/

I took the best of the above and added the ability to work with any input, outside of forms, etc. Also it properly loops back to start now if you reach the last input. And in the event of only one input it blurs then refocuses the single input to trigger any external blur/focus handlers.

$('input,select').keydown( function(e) {
  var key = e.charCode ? e.charCode : e.keyCode ? e.keyCode : 0;
  if(key == 13) {
    e.preventDefault();
    var inputs = $('#content').find(':input:visible');
    var nextinput = 0;
    if (inputs.index(this) < (inputs.length-1)) {
      nextinput = inputs.index(this)+1;
    }
    if (inputs.length==1) {
      $(this).blur().focus();
    } else {
      inputs.eq(nextinput).focus();
    }
  }
});

You can use this:

select
    table_name,column_name,referenced_table_name,referenced_column_name
from
    information_schema.key_column_usage
where
    referenced_table_name is not null
    and table_schema = 'my_database' 
    and table_name = 'my_table'

Or for better formatted output use this:

select
    concat(table_name, '.', column_name) as 'foreign key',  
    concat(referenced_table_name, '.', referenced_column_name) as 'references'
from
    information_schema.key_column_usage
where
    referenced_table_name is not null
    and table_schema = 'my_database' 
    and table_name = 'my_table'

Facing the same issue using Eclipse and a distant Oracle Database, changing my system time zone to match the time zone of the database server fixed the problem. Re-start the machine after changing system time zone.

I hope this can help someone

Try running

lsof | grep /mnt/data

That should list any process that is accessing /mnt/data that would prevent it from being unmounted.

I use PropertyResourceBundle to define the error codes in an enterprise application to manage locale error code resources. This is the best way to handle error codes instead of writing code (may be hold good for few error codes) when the number of error codes are huge and structured.

Look at java doc for more information on PropertyResourceBundle

I know that this is a quite old thread, but here is an updated version for Integers and Java 8:

Arrays.sort(array, (o1, o2) -> o2 - o1);

Note that it is "o1 - o2" for the normal ascending order (or Comparator.comparingInt()).

This also works for any other kinds of Objects. Say:

Arrays.sort(array, (o1, o2) -> o2.getValue() - o1.getValue());

If you are using the GNU C library or another POSIX-compliant library, you can use getline() and pass stdin to it for the file stream.

Using MySQL Workbench it's easy to select several tables and run a search for text in all those tables of the DB ;-)

Use a for loop to iterate through your array. For each string, create a new option element, assign the string as its innerHTML and value, and then append it to the select element.

var cuisines = ["Chinese","Indian"];     
var sel = document.getElementById('CuisineList');
for(var i = 0; i < cuisines.length; i++) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisines[i];
    opt.value = cuisines[i];
    sel.appendChild(opt);
}

DEMO

UPDATE: Using createDocumentFragment and forEach

If you have a very large list of elements that you want to append to a document, it can be non-performant to append each new element individually. The DocumentFragment acts as a light weight document object that can be used to collect elements. Once all your elements are ready, you can execute a single appendChild operation so that the DOM only updates once, instead of n times.

var cuisines = ["Chinese","Indian"];     

var sel = document.getElementById('CuisineList');
var fragment = document.createDocumentFragment();

cuisines.forEach(function(cuisine, index) {
    var opt = document.createElement('option');
    opt.innerHTML = cuisine;
    opt.value = cuisine;
    fragment.appendChild(opt);
});

sel.appendChild(fragment);

In my case I removed the server logon credentials for central from my setting.

    <server> 
        <id>central</id>
        <username>admin</username>

        <url>http://www.localhost:8081/repository/maven-central/</url>
   </mirror> 

I don't know why I did that, but its completely wrong since the central maven repo can be accessed anonymously. See my debug output that led to my error identification and resolution.

Seeing from your G++ version, you need to update it badly. C++11 has only been available since G++ 4.3. The most recent version is 4.7.

In versions pre-G++ 4.7, you'll have to use -std=c++0x, for more recent versions you can use -std=c++11.

A lot of these answers are simplistic, and if someone is beginning WPF, they may not know all of the "ins-and-outs", as it is more complicated than just telling someone "Use .ShowDialog()!". But that is the method (not .Show()) that you want to use in order to block use of the underlying window and to keep the code from continuing until the modal window is closed.

First, you need 2 WPF windows. (One will be calling the other.)

From the first window, let's say that was called MainWindow.xaml, in its code-behind will be:

public partial class MainWindow : Window
{
    public MainWindow()
    {
        InitializeComponent();
    }
}

Then add your button to your XAML:

<Button Name="btnOpenModal" Click="btnOpenModal_Click" Content="Open Modal" />

And right-click the Click routine, select "Go to definition". It will create it for you in MainWindow.xaml.cs:

private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
}

Within that function, you have to specify the other page using its page class. Say you named that other page "ModalWindow", so that becomes its page class and is how you would instantiate (call) it:

private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
    ModalWindow modalWindow = new ModalWindow();
    modalWindow.ShowDialog();
}

Say you have a value you need set on your modal dialog. Create a textbox and a button in the ModalWindow XAML:

<StackPanel Orientation="Horizontal">
    <TextBox Name="txtSomeBox" />
    <Button Name="btnSaveData" Click="btnSaveData_Click" Content="Save" /> 
</StackPanel>

Then create an event handler (another Click event) again and use it to save the textbox value to a public static variable on ModalWindow and call this.Close().

public partial class ModalWindow : Window
{
    public static string myValue = String.Empty;        
    public ModalWindow()
    {
        InitializeComponent();
    }

    private void btnSaveData_Click(object sender, RoutedEventArgs e)
    {
        myValue = txtSomeBox.Text;
        this.Close();
    }
}

Then, after your .ShowDialog() statement, you can grab that value and use it:

private void btnOpenModal_Click(object sender, RoutedEventArgs e)
{
    ModalWindow modalWindow = new ModalWindow();
    modalWindow.ShowDialog();

    string valueFromModalTextBox = ModalWindow.myValue;
}

In Python 3.2 and later, use

>>> int.from_bytes(b'y\xcc\xa6\xbb', byteorder='big')
2043455163

or

>>> int.from_bytes(b'y\xcc\xa6\xbb', byteorder='little')
3148270713

according to the endianness of your byte-string.

This also works for bytestring-integers of arbitrary length, and for two's-complement signed integers by specifying signed=True. See the docs for from_bytes.

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

Here;this is the solution.

For nodejs log file you can use winston and morgan and in place of your console.log() statement user winston.log() or other winston methods to log. For working with winston and morgan you need to install them using npm. Example: npm i -S winston npm i -S morgan

Then create a folder in your project with name winston and then create a config.js in that folder and copy this code given below.

const appRoot = require('app-root-path');
const winston = require('winston');

// define the custom settings for each transport (file, console)
const options = {
  file: {
    level: 'info',
    filename: `${appRoot}/logs/app.log`,
    handleExceptions: true,
    json: true,
    maxsize: 5242880, // 5MB
    maxFiles: 5,
    colorize: false,
  },
  console: {
    level: 'debug',
    handleExceptions: true,
    json: false,
    colorize: true,
  },
};

// instantiate a new Winston Logger with the settings defined above
let logger;
if (process.env.logging === 'off') {
  logger = winston.createLogger({
    transports: [
      new winston.transports.File(options.file),
    ],
    exitOnError: false, // do not exit on handled exceptions
  });
} else {
  logger = winston.createLogger({
    transports: [
      new winston.transports.File(options.file),
      new winston.transports.Console(options.console),
    ],
    exitOnError: false, // do not exit on handled exceptions
  });
}

// create a stream object with a 'write' function that will be used by `morgan`
logger.stream = {
  write(message) {
    logger.info(message);
  },
};

module.exports = logger;

After copying the above code make make a folder with name logs parallel to winston or wherever you want and create a file app.log in that logs folder. Go back to config.js and set the path in the 5th line "filename: ${appRoot}/logs/app.log, " to the respective app.log created by you.

After this go to your index.js and include the following code in it.

const morgan = require('morgan');
const winston = require('./winston/config');
const express = require('express');
const app = express();
app.use(morgan('combined', { stream: winston.stream }));

winston.info('You have successfully started working with winston and morgan');

There is but one difference. You have to take care or name mangling win C++. But on windows you have to take care about 1) decrating the functions to be exported from the DLL 2) write a so called .def file which lists all the exported symbols.

In Windows while compiling a DLL have have to use

__declspec(dllexport)

but while using it you have to write __declspec(dllimport)

So the usual way of doing that is something like

#ifdef BUILD_DLL
#define EXPORT __declspec(dllexport)
#else
#define EXPORT __declspec(dllimport)
#endif

The naming is a bit confusing, because it is often named EXPORT.. But that's what you'll find in most of the headers somwhere. So in your case you'd write (with the above #define)

int DLL_EXPORT add.... int DLL_EXPORT mult...

Remember that you have to add the Preprocessor directive BUILD_DLL during building the shared library.

This variant is better because you could not know whether file exists or not. You should send correct header when you know for certain that you can read contents of your file. Also, if you have branches of code that does not finish with '.end()', browser will wait until it get them. In other words, your browser will wait a long time.

var fs = require("fs");
var filename = "./index.html";

function start(resp) {

    fs.readFile(filename, "utf8", function(err, data) {
        if (err) {
            // may be filename does not exists?
            resp.writeHead(404, {
                'Content-Type' : 'text/html'
            });
            // log this error into browser
            resp.write(err.toString());
            resp.end();
        } else {

            resp.writeHead(200, {
                "Content-Type": "text/html"
            });      
            resp.write(data.toString());
            resp.end();
        }
    });
}

According to w3.org (note that this link is in the long-expired draft HTML 3.0 spec):

An unordered list typically is a bulleted list of items. HTML 3.0 gives you the ability to customise the bullets, to do without bullets and to wrap list items horizontally or vertically for multicolumn lists.

The opening list tag must be <UL>. It is followed by an optional list header (<LH>caption</LH>) and then by the first list item (<LI>). For example:

<UL>
  <LH>Table Fruit</LH>
  <LI>apples
  <LI>oranges
  <LI>bananas
</UL>

which could be rendered as:

Table Fruit

• apples
• oranges
• bananas

Note: Some legacy documents may include headers or plain text before the first LI element. Implementors of HTML 3.0 user agents are advised to cater for this possibility in order to handle badly formed legacy documents.

If you are reusing an element over and over (A bootstrap modal dialog in my case), then calling ko.applyBindings(el) multiple times will cause this problem.

Instead just do it once like this:

if (!applied) {
    ko.applyBindings(el);
    applied = true;
}

Or like this:

var apply = function (viewModel, containerElement) {
    ko.applyBindings(viewModel, containerElement);
    apply = function() {}; // only allow this function to be called once.
}

PS: This might happen more often to you if you use the mapping plugin and convert your JSON data to observables.

The CPP Section of the GCC Manual indicates that header files may be located in the following directories:

GCC looks in several different places for headers. On a normal Unix system, if you do not instruct it otherwise, it will look for headers requested with #include in:

 /usr/local/include
 libdir/gcc/target/version/include
 /usr/target/include
 /usr/include

For C++ programs, it will also look in /usr/include/g++-v3, first.

I too had that same problem.. If we think logically little bit we can get the answer.. It worked for me very well.. I hope u will get it..

1. listviewdemo.xml

   <ListView
       android:id="@+id/listview"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:paddingBottom="30dp"
       android:paddingLeft="10dp"
       android:paddingRight="10dp" />
   

2. listviewcontent.xml - note that TextView - android:id="@+id/txtLstItem"

   <LinearLayout
       android:id="@+id/listviewcontentlayout"
       android:layout_width="0dp"
       android:layout_height="fill_parent"
       android:layout_weight="1"
       android:orientation="horizontal">
   
       <ImageView
           android:id="@+id/img1"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:layout_marginRight="6dp" />
   
       <LinearLayout
           android:layout_width="0dp"
           android:layout_height="fill_parent"
           android:layout_weight="1"
           android:orientation="vertical">
   
           <TextView
               android:id="@+id/txtLstItem"
               android:layout_width="match_parent"
               android:layout_height="wrap_content"
               android:gravity="left"
               android:shadowColor="@android:color/black"
               android:shadowRadius="5"
               android:textColor="@android:color/white" />
   
       </LinearLayout>
   
       <ImageView
           android:id="@+id/img2"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:layout_marginRight="6dp" />
   </LinearLayout>
   

3. ListViewActivity.java - Note that view.findViewById(R.id.txtLstItem) - as we setting the value to TextView by setText() method we getting text from TextView by View object returned by onItemClick method. OnItemClick() returns the current view.

   TextView v=(TextView) view.findViewById(R.id.txtLstItem);
   Toast.makeText(getApplicationContext(), "selected Item Name is "+v.getText(), Toast.LENGTH_LONG).show();**
   

   Using this simple logic we can get other values like CheckBox, RadioButton, ImageView etc.

   ListView List = (ListView) findViewById(R.id.listview);
   cursor = cr.query(CONTENT_URI,projection,null,null,null);
   adapter = new ListViewCursorAdapter(ListViewActivity.this, R.layout.listviewcontent, cursor, from, to);
   
   cursor.moveToFirst();
   
   // Let activity manage the cursor
   startManagingCursor(cursor);
   
   List.setAdapter(adapter);
   List.setOnItemClickListener(new AdapterView.OnItemClickListener() {
           @Override
           public void onItemClick (AdapterView < ? > adapter, View view,int position, long arg){
               // TODO Auto-generated method stub
               TextView v = (TextView) view.findViewById(R.id.txtLstItem);
               Toast.makeText(getApplicationContext(), "selected Item Name is " + v.getText(), Toast.LENGTH_LONG).show();
           }
       }
   );
   

This is an improved version of Anne's answer -- if you use perl, you can do the edit on the file 'in-place' rather than generating a new file:

perl -pi -e 's/\r\n|\n|\r/\r\n/g' file-to-convert  # Convert to DOS
perl -pi -e 's/\r\n|\n|\r/\n/g'   file-to-convert  # Convert to UNIX

keep this into your web config file then rename the add value="yourwebformname.aspx"

<system.webServer>
    <defaultDocument>
       <files>
          <add value="insertion.aspx" />
       </files>
    </defaultDocument>
    <directoryBrowse enabled="false" />
</system.webServer>

else

<system.webServer>
    <directoryBrowse enabled="true" />
</system.webServer>

Yes, continue will be ignored by the switch statement and will go to the condition of the loop to be tested. I'd like to share this extract from The C Programming Language reference by Ritchie:

The continue statement is related to break, but less often used; it causes the next iteration of the enclosing for, while, or do loop to begin. In the while and do, this means that the test part is executed immediately; in the for, control passes to the increment step.

The continue statement applies only to loops, not to a switch statement. A continue inside a switch inside a loop causes the next loop iteration.

I'm not sure about that for C++.

Thought I'd add a bit to the answer.

If you have multiple URL definitions then you'll have to name each of them separately. So you lose the flexibility when calling reverse since one reverse will expect a parameter while the other won't.

Another way to use regex to accommodate the optional parameter:

r'^project_config/(?P<product>\w+)/((?P<project_id>\w+)/)?$'

Try this:

// this will fix old browsers
if (!Array.prototype.indexOf) {
  Array.prototype.indexOf = function(value) {
    for (var i = 0; i < this.length; i++) {
      if (this[i] === value) {
        return i;
      }
    }

    return -1;
  }
}

// example
if ([1, 2, 3].indexOf(2) != -1) {
  // yay!
}

before you begin this program get rid of all the code and do a simple hello world inside of main. Only include iostream and using namespace std;. Little by little add to it to find your issue.

cout << "hi" << endl;

I hit this error ("stat /bin/bash: no such file or directory") when running the command:

docker exec -it 80372bc2c41e /bin/bash

The solution was to identify the kind of terminal (or shell) that is available on the container. To do so, I ran:

docker inspect 80372bc2c41e

In the output from that command, I saw:

"Cmd": [
    "/bin/sh",
    "-c",
    "gunicorn -b 0.0.0.0:7082 server.app:app"
],

This tells me that there's a /bin/sh command available, and I was able to connect with:

docker exec -it 80372bc2c41e /bin/sh

int is a primitive type and not an object. That means that there are no methods associated with it. Integer is an object with methods (such as parseInt).

With newer java there is functionality for auto boxing (and unboxing). That means that the compiler will insert Integer.valueOf(int) or integer.intValue() where needed. That means that it is actually possible to write

Integer n = 9;

which is interpreted as

Integer n = Integer.valueOf(9);

Use string concatenation:

href={'/posts/' + post.id}

The JSX syntax allows either to use strings or expressions ({...}) as values. You cannot mix both. Inside an expression you can, as the name suggests, use any JavaScript expression to compute the value.

There is a better answer to this problem, though I could just break this down step-by-step.

You will need to fetch and checkout the latest upstream changes like so, e.g.:

git fetch upstream
git checkout upstream/master -b revert/john/foo_and_bar

Taking a look at the commit log, you should find something similar to this:

commit b76a5f1f5d3b323679e466a1a1d5f93c8828b269
Merge: 9271e6e a507888
Author: Tim Tom <[email protected]>
Date:   Mon Apr 29 06:12:38 2013 -0700

    Merge pull request #123 from john/foo_and_bar

    Add foo and bar

commit a507888e9fcc9e08b658c0b25414d1aeb1eef45e
Author: John Doe <[email protected]>
Date:   Mon Apr 29 12:13:29 2013 +0000

    Add bar

commit 470ee0f407198057d5cb1d6427bb8371eab6157e
Author: John Doe <[email protected]>
Date:   Mon Apr 29 10:29:10 2013 +0000

    Add foo

Now you want to revert the entire pull request with the ability to unrevert later. To do so, you will need to take the ID of the merge commit.

In the above example the merge commit is the top one where it says "Merged pull request #123...".

Do this to revert the both changes ("Add bar" and "Add foo") and you will end up with in one commit reverting the entire pull request which you can unrevert later on and keep the history of changes clean:

git revert -m 1 b76a5f1f5d3b323679e466a1a1d5f93c8828b269

I had the same problem and was solved by running the following in run

%windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe -i

just wrote a small bash script to do this using curl

https://gist.github.com/harish2704/bfb8abece94893c53ce344548ead8ba5

#!/usr/bin/env bash

# Usage: gdrive_dl.sh <url>

urlBase='https://drive.google.com'
fCookie=tmpcookies

curl="curl -L -b $fCookie -c $fCookie"
confirm(){
    $curl "$1" | grep jfk-button-action | sed -e 's/.*jfk-button-action" href="\(\S*\)".*/\1/' -e 's/\&amp;/\&/g'
}

$curl -O -J "${urlBase}$(confirm $1)"

You can use the below lines of code to change the background of the Checkbox dynamically in your java code.

//Setting up background color on checkbox.
 checkbox.setBackgroundColor(Color.parseColor("#00e2a5"));

This answer was from this site. You can also use this site to convert your RGB color to the Hex value, you need to feed the parseColor

You can make an AJAX request if the url is in the same domain, e.g., same host different application. If so, I'd probably use a framework like jQuery, most likely the get method.

$.get('http://someurl.com',function(data,status) {
      ...parse the data...
},'html');

If you run into cross domain issues, then your best bet is to create a server-side action that proxies the request for you. Do your request to your server using AJAX, have the server request and return the response from the external host.

Thanks to@nickf, for pointing out the obvious problem with my original solution if the url is in a different domain.

The general idea is to add, commit and push your files to the GitHub repo.

First you need to clone your GitHub repo.
Then, you would git add all the files from your other folder: one trick is to specify an alternate working tree when git add'ing your files.

git --work-tree=yourSrcFolder add .

(done from the root directory of your cloned Git repo, then git commit -m "a msg", and git push origin master)

That way, you keep separate your initial source folder, from your Git working tree.

Note that since early December 2012, you can create new files directly from GitHub:

ProTip™: You can pre-fill the filename field using just the URL.
Typing ?filename=yournewfile.txt at the end of the URL will pre-fill the filename field with the name yournewfile.txt.

Somehow I got it to work by using margin-right, and setting it to move from right to left. http://jsfiddle.net/gXdMc/

Don't know why for this case, margin-right 100% doesn't go off the screen. :D (tested on chrome 18)

EDIT: now left to right works too http://jsfiddle.net/6LhvL/

On Mac OS X:

md5 -q file

Found another way, just for fun.

function IsActuallyNaN(obj) {
  return [obj].includes(NaN);  
}

Please create a custom TextView and use it :

public class CustomTextView extends TextView {

    public CapitalizedTextView(Context context, AttributeSet attrs) {
        super(context, attrs);
    }

    @Override
    public void setText(CharSequence text, BufferType type) {
        if (text.length() > 0) {
            text = String.valueOf(text.charAt(0)).toUpperCase() + text.subSequence(1, text.length());
        }
        super.setText(text, type);
    }
}

This code works for me

<meta name="text" property="text" content="This is text" />
<meta name="video" property="text" content="http://video.com/video33353.mp4" />

JS

var x = document.getElementsByTagName("META");
    var txt = "";
    var i;
    for (i = 0; i < x.length; i++) {
        if (x[i].name=="video")
        {
             alert(x[i].content);
         }

    }

In C++ you can overload operator<< for ostream and your custom class:

class A {
public:
  int i;
};

std::ostream& operator<<(std::ostream &strm, const A &a) {
  return strm << "A(" << a.i << ")";
}

This way you can output instances of your class on streams:

A x = ...;
std::cout << x << std::endl;

In case your operator<< wants to print out internals of class A and really needs access to its private and protected members you could also declare it as a friend function:

class A {
private:
  friend std::ostream& operator<<(std::ostream&, const A&);
  int j;
};

std::ostream& operator<<(std::ostream &strm, const A &a) {
  return strm << "A(" << a.j << ")";
}

The return statement stops the execution of a function and returns a value from that function.

While updating global variables is one way to pass information back to the code that called the function, this is not an ideal way of doing so. A much better alternative is to write the function so that values that are used by the function are passed to it as parameters and the function returns whatever value that it needs to without using or updating any global variables.

By limiting the way in which information is passed to and from functions we can make it easier to reuse the same function from multiple places in our code.

JavaScript provides for passing one value back to the code that called it after everything in the function that needs to run has finished running.

JavaScript passes a value from a function back to the code that called it by using the return statement. The value to be returned is specified in the return keyword.

button.setBackgroundColor(getResources().getColor(R.color.red);

Sets the background color for this view. Parameters: color the color of the background

R.color.red is a reference generated at the compilation in gen.

I found out one more way: You can check if /usr/local/var/run/nginx.pid exists. If it is - nginx is running. Useful way for scripting.

Example:

if [ -f /usr/local/var/run/nginx.pid ]; then
   echo "Nginx is running"
