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

You can try this code for converting bytes from packet to a null-terminated string and store to "string" variable for processing.

const int buffer_size = 2048;
// variable for storing buffer as printable HEX string
char data[buffer_size*2];
// receive message from socket
int ret = recvfrom(sock, buffer, sizeofbuffer, 0, reinterpret_cast<SOCKADDR *>(&from), &size);
// bytes converting cycle
for (int i=0,j=0; i<ret; i++,j+=2){ 
    char res[2]; 
    itoa((buffer[i] & 0xFF), res, 16);
        if (res[1] == 0) {
            data[j] = 0x30; data[j+1] = res[0];
        }else {
            data[j] = res[0]; data[j + 1] = res[1];
        }
}
// Null-Terminating the string with converted buffer
data[(ret * 2)] = 0;

When we send message with hex bytes 0x01020E0F, variable "data" had char array with string "01020e0f".

Have you considered mmap()? You can read from the file directly as if it were already in memory.

http://beej.us/guide/bgipc/output/html/multipage/mmap.html

Flushing the output buffers:

printf("Buffered, will be flushed");
fflush(stdout); // Prints to screen or whatever your standard out is

or

fprintf(fd, "Buffered, will be flushed");
fflush(fd);  //Prints to a file

Can be a very helpful technique. Why would you want to flush an output buffer? Usually when I do it, it's because the code is crashing and I'm trying to debug something. The standard buffer will not print everytime you call printf() it waits until it's full then dumps a bunch at once. So if you're trying to check if you're making it to a function call before a crash, it's helpful to printf something like "got here!", and sometimes the buffer hasn't been flushed before the crash happens and you can't tell how far you've really gotten.

Another time that it's helpful, is in multi-process or multi-thread code. Again, the buffer doesn't always flush on a call to a printf(), so if you want to know the true order of execution of multiple processes you should fflush the buffer after every print.

I make a habit to do it, it saves me a lot of headache in debugging. The only downside I can think of to doing so is that printf() is an expensive operation (which is why it doesn't by default flush the buffer).

As far as flushing the input buffer (stdin), you should not do that. Flushing stdin is undefined behavior according to the C11 standard §7.21.5.2 part 2:

If stream points to an output stream ... the fflush function causes any unwritten data for that stream ... to be written to the file; otherwise, the behavior is undefined.

On some systems, Linux being one as you can see in the man page for fflush(), there's a defined behavior but it's system dependent so your code will not be portable.

Now if you're worried about garbage "stuck" in the input buffer you can use fpurge() on that. See here for more on fflush() and fpurge()

But I cannot explain myself how it works? Because in the while statement, we use getchar() != '\n', that means read any single character except '\n'?? if so, in the input buffer still remains the '\n' character??? Am I misunderstanding something??

The thing you may not realize is that the comparison happens after getchar() removes the character from the input buffer. So when you reach the '\n', it is consumed and then you break out of the loop.

The ByteBuffer class is important because it forms a basis for the use of channels in Java. ByteBuffer class defines six categories of operations upon byte buffers, as stated in the Java 7 documentation:

• Absolute and relative get and put methods that read and write single bytes;

• Relative bulk get methods that transfer contiguous sequences of bytes from this buffer into an array;

• Relative bulk put methods that transfer contiguous sequences of bytes from a byte array or some other byte buffer into this buffer;

• Absolute and relative get and put methods that read and write values of other primitive types, translating them to and from sequences of bytes in a particular byte order;

• Methods for creating view buffers, which allow a byte buffer to be viewed as a buffer containing values of some other primitive type; and

• Methods for compacting, duplicating, and slicing a byte buffer.

Example code : Putting Bytes into a buffer.

    // Create an empty ByteBuffer with a 10 byte capacity
    ByteBuffer bbuf = ByteBuffer.allocate(10);

    // Get the buffer's capacity
    int capacity = bbuf.capacity(); // 10

    // Use the absolute put(int, byte).
    // This method does not affect the position.
    bbuf.put(0, (byte)0xFF); // position=0

    // Set the position
    bbuf.position(5);

    // Use the relative put(byte)
    bbuf.put((byte)0xFF);

    // Get the new position
    int pos = bbuf.position(); // 6

    // Get remaining byte count
    int rem = bbuf.remaining(); // 4

    // Set the limit
    bbuf.limit(7); // remaining=1

    // This convenience method sets the position to 0
    bbuf.rewind(); // remaining=7

This is not how you initialize an array, but for:

1. The first declaration:

   char buf[10] = "";
   

   is equivalent to

   char buf[10] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0};
   

2. The second declaration:

   char buf[10] = " ";
   

   is equivalent to

   char buf[10] = {' ', 0, 0, 0, 0, 0, 0, 0, 0, 0};
   

3. The third declaration:

   char buf[10] = "a";
   

   is equivalent to

   char buf[10] = {'a', 0, 0, 0, 0, 0, 0, 0, 0, 0};
   

As you can see, no random content: if there are fewer initializers, the remaining of the array is initialized with 0. This the case even if the array is declared inside a function.

Quote from the book: Introduction to Information Retrieval

Cache

We want to keep as much data as possible in memory, especially those data that we need to access frequently. We call the technique of keeping frequently used disk data in main memory caching.

Buffer

Operating systems generally read and write entire blocks. Thus, reading a single byte from disk can take as much time as reading the entire block. Block sizes of 8, 16, 32, and 64 kilobytes (KB) are common. We call the part of main memory where a block being read or written is stored a buffer.

I have already update my node to Version 5.0.0 And I work work with this:

function toArrayBuffer(buffer){
    var array = [];
    var json = buffer.toJSON();
    var list = json.data

    for(var key in list){
        array.push(fixcode(list[key].toString(16)))
    }

    function fixcode(key){
        if(key.length==1){
            return '0'+key.toUpperCase()
        }else{
            return key.toUpperCase()
        }
    }

    return array
}

I use it to check my vhd disk image.

I suggest creating a new StringBuffer (or even better, StringBuilder) for each iteration. The performance difference is really negligible, but your code will be shorter and simpler.

A word of caution: “the w in bw does not stand for write but for wipeout!”

More from manuals:

:bd

Unload buffer [N] (default: current buffer) and delete it from the buffer list. If the buffer was changed, this fails, unless when [!] is specified, in which case changes are lost. The file remains unaffected.

If you know what you’re doing, you can also use :bw

:bw

Like |:bdelete|, but really delete the buffer.

For getting the buffer size in c/c++ program the following is the flow

int n;
unsigned int m = sizeof(n);
int fdsocket;
fdsocket = socket(AF_INET,SOCK_DGRAM,IPPROTO_UDP); // example
getsockopt(fdsocket,SOL_SOCKET,SO_RCVBUF,(void *)&n, &m);
// now the variable n will have the socket size

Here is a short example, the C++ way using rdbuf. I got this from the web. I can't find my original source on this:

#include <fstream>
#include <iostream>

int main () 
{
  std::ifstream f1 ("C:\\me.txt",std::fstream::binary);

  std::ofstream f2 ("C:\\me2.doc",std::fstream::trunc|std::fstream::binary);

  f2<<f1.rdbuf();

  return 0;
}

Or you can send a page break (ASCII form feed) by pressing Ctrl + L.

While this technically just starts a new page, this has the same net effect as all the other methods, while being a lot faster (except for the Apple + K solution, of course).

And because this is an ASCII control command, and it works in all shells.

public static  byte[] my_int_to_bb_le(int myInteger){
    return ByteBuffer.allocate(4).order(ByteOrder.LITTLE_ENDIAN).putInt(myInteger).array();
}

public static int my_bb_to_int_le(byte [] byteBarray){
    return ByteBuffer.wrap(byteBarray).order(ByteOrder.LITTLE_ENDIAN).getInt();
}

public static  byte[] my_int_to_bb_be(int myInteger){
    return ByteBuffer.allocate(4).order(ByteOrder.BIG_ENDIAN).putInt(myInteger).array();
}

public static int my_bb_to_int_be(byte [] byteBarray){
    return ByteBuffer.wrap(byteBarray).order(ByteOrder.BIG_ENDIAN).getInt();
}

16kb is about right; if you're using gigabit ethernet, each packet could be 9kb in size.

Optimum buffer size is related to a number of things: file system block size, CPU cache size and cache latency.

Most file systems are configured to use block sizes of 4096 or 8192. In theory, if you configure your buffer size so you are reading a few bytes more than the disk block, the operations with the file system can be extremely inefficient (i.e. if you configured your buffer to read 4100 bytes at a time, each read would require 2 block reads by the file system). If the blocks are already in cache, then you wind up paying the price of RAM -> L3/L2 cache latency. If you are unlucky and the blocks are not in cache yet, the you pay the price of the disk->RAM latency as well.

This is why you see most buffers sized as a power of 2, and generally larger than (or equal to) the disk block size. This means that one of your stream reads could result in multiple disk block reads - but those reads will always use a full block - no wasted reads.

Now, this is offset quite a bit in a typical streaming scenario because the block that is read from disk is going to still be in memory when you hit the next read (we are doing sequential reads here, after all) - so you wind up paying the RAM -> L3/L2 cache latency price on the next read, but not the disk->RAM latency. In terms of order of magnitude, disk->RAM latency is so slow that it pretty much swamps any other latency you might be dealing with.

So, I suspect that if you ran a test with different cache sizes (haven't done this myself), you will probably find a big impact of cache size up to the size of the file system block. Above that, I suspect that things would level out pretty quickly.

There are a ton of conditions and exceptions here - the complexities of the system are actually quite staggering (just getting a handle on L3 -> L2 cache transfers is mind bogglingly complex, and it changes with every CPU type).

This leads to the 'real world' answer: If your app is like 99% out there, set the cache size to 8192 and move on (even better, choose encapsulation over performance and use BufferedInputStream to hide the details). If you are in the 1% of apps that are highly dependent on disk throughput, craft your implementation so you can swap out different disk interaction strategies, and provide the knobs and dials to allow your users to test and optimize (or come up with some self optimizing system).

Ctrl+A then Shift+H works for me. You can view the file screenlog.0 while the program is still running.

insert byte to specific place.

insertToArray(arr,index,item) {
   return Buffer.concat([arr.slice(0,index),Buffer.from(item,"utf-8"),arr.slice(index)]);
}

You need to stringify the json, not calling toString

var buf = Buffer.from(JSON.stringify(obj));

And for converting string to json obj :

var temp = JSON.parse(buf.toString());

Since they are already inline-block child elements, you can set text-align:center on the parent without having to set a width or margin:0px auto on the child. Meaning it will work for dynamically generated content with varying widths.

.img_container, .img_container2 {
    text-align: center;
}

This will center the child within both div containers.

UPDATE:

For vertical centering, you can use the calc() function assuming the height of the icon is known.

.img_container > i, .img_container2 > i {
    position:relative;
    top: calc(50% - 10px); /* 50% - 3/4 of icon height */
}

jsFiddle demo - it works.

For what it's worth - you can also use vertical-align:middle assuming display:table-cell is set on the parent.

Since PHP 5.4 you can use http_response_code.

http_response_code(404);

This will take care of setting the proper HTTP headers.

If you are running PHP < 5.4 then you have two options:

1. Upgrade.
2. Use this http_response_code function implemented in PHP.

Don't fear the Exception! Having your program just log and continue is as easy as:

try:
    result = simulate(open("myfile"))
except SimulationException as sim_exc:
    print "error parsing stream", sim_exc
else:
    if result:
        print "result pass"
    else:
        print "result fail"

# execution continues from here, regardless of exception or not

And now you can have a much richer type of notification from the simulate method as to what exactly went wrong, in case you find error/no-error not to be informative enough.

You can use this syntax: node.parentNode

For example:

someNode = document.getElementById("someId");
someNode.parentNode.removeChild(someNode);

Not sure what the problem is, this seems to work just fine?

DECLARE @StartDate AS DATETIME
DECLARE @EndDate AS DATETIME

SET @StartDate = NULL
SET @EndDate = NULL

IF (@StartDate IS NOT NULL AND @EndDate IS NOT NULL) 
    BEGIN
        Select 'This works just fine' as Msg
    END
Else
    BEGIN
    Select 'No Lol' as Msg
    END

Edit the following entry in the run.conf file. But if you have multiple JVMs running on the same JBoss, you might want to run it via command line argument of -Xms2g -Xmx4g (or whatever your preferred start/max memory settings are.

if [ "x$JAVA_OPTS" = "x" ]; then
    JAVA_OPTS="-Xms2g -Xmx4g -XX:MaxPermSize=256m -Dorg.jboss.resolver.warning=true

Use .AddRange to append any Enumrable collection to the list.

Here is an example using openssl_encrypt

//Encryption:
$textToEncrypt = "My Text to Encrypt";
$encryptionMethod = "AES-256-CBC";
$secretHash = "encryptionhash";
$iv = mcrypt_create_iv(16, MCRYPT_RAND);
$encryptedText = openssl_encrypt($textToEncrypt,$encryptionMethod,$secretHash, 0, $iv);

//Decryption:
$decryptedText = openssl_decrypt($encryptedText, $encryptionMethod, $secretHash, 0, $iv);
print "My Decrypted Text: ". $decryptedText;

just in case someone is getting NullPointerException, you need to get the context inside onCreate().

Service is a Context, so do this:

@Override
public void onCreate() {
    super.onCreate();
    context = this;
}

Consider the second script. If you import it in another one, the instructions, as at "global level", will be executed.

I would suggest a more lightweight approach for traversing the complete responder chain without having to add a category on UIView:

@implementation MyUIViewSubclass

- (UIViewController *)viewController {
    UIResponder *responder = self;
    while (![responder isKindOfClass:[UIViewController class]]) {
        responder = [responder nextResponder];
        if (nil == responder) {
            break;
        }
    }
    return (UIViewController *)responder;
}

@end

Yes you can. You can even test it:

var i = 0;_x000D_
var timer = setInterval(function() {_x000D_
  console.log(++i);_x000D_
  if (i === 5) clearInterval(timer);_x000D_
  console.log('post-interval'); //this will still run after clearing_x000D_
}, 200);

In this example, this timer clears when i reaches 5.

How about subclassing json.JSONEncoder?

class DecimalEncoder(json.JSONEncoder):
    def default(self, o):
        if isinstance(o, decimal.Decimal):
            # wanted a simple yield str(o) in the next line,
            # but that would mean a yield on the line with super(...),
            # which wouldn't work (see my comment below), so...
            return (str(o) for o in [o])
        return super(DecimalEncoder, self).default(o)

Then use it like so:

json.dumps({'x': decimal.Decimal('5.5')}, cls=DecimalEncoder)

In addition to Jon Skeet's answer, I'd like to explain why most of the time when using == you actually get the answer true on different string instances with the same value:

string a = "Hell";
string b = "Hello";
a = a + "o";
Console.WriteLine(a == b);

As you can see, a and b must be different string instances, but because strings are immutable, the runtime uses so called string interning to let both a and b reference the same string in memory. The == operator for objects checks reference, and since both a and b reference the same instance, the result is true. When you change either one of them, a new string instance is created, which is why string interning is possible.

By the way, Jon Skeet's answer is not complete. Indeed, x == y is false but that is only because he is comparing objects and objects compare by reference. If you'd write (string)x == (string)y, it will return true again. So strings have their ==-operator overloaded, which calls String.Equals underneath.

Oracle views like ALL_TABLES and ALL_CONSTRAINTS have an owner column, which you can use to restrict your query. There are also variants of these tables beginning with USER instead of ALL, which only list objects which can be accessed by the current user.

One of these views should help to solve your problem. They always worked fine for me for similar problems.

There is not an equivalent statement for export in Windows Command Prompt. In Windows the environment is copied so when you exit from the session (from a called command prompt or from an executable that set a variable) the variable in Windows get lost. You can set it in user registry or in machine registry via setx but you won't see it if you not start a new command prompt.

For what it's worth, when I did this I found that no folder should be include in the path in the css file. For instance if I have app/assets/images/example.png, and I put this in my css file...

div.example { background: url('example.png'); }

... then somehow it magically works. I figured this out by running the rake assets:precompile task, which just sucks everything out of all your load paths and dumps it in a junk drawer folder: public/assets. That's ironic, IMO...

In any case this means you don't need to put any folder paths, everything in your assets folders will all end up living in one huge directory. How this system resolves file name conflicts is unclear, you may need to be careful about that.

Kind of frustrating there aren't better docs out there for this big of a change.

Random random = new Random();

double NextDouble(double minimum, double maximum)
{  

    return random.NextDouble()*random.Next(minimum,maximum);

}

The error says Cannot assign requested address. This means that you need to use the correct address for one of your network interfaces or 0.0.0.0 to accept connections from all interfaces.

The other solutions about ports only work after sometimes-failing black magic (like working after some computer restarts but not others) because the port is completely irrelevant.

onclick = "setTimeout(function() { document.getElementById('div1').style.display='none';document.getElementById('div2').style.display='none'}, 1000)"

Change 1000 to the number of milliseconds you want to delay.

if you open localhost/phpmyadmin you will find a tab called "User accounts". There you can define all your users that can access the mysql database, set their rights and even limit from where they can connect.

To get body lines use escape()

body_line =  escape("\n");

so

href = "mailto:[email protected]?body=hello,"+body_line+"I like this.";

Or without the year:

DateTime.Now.ToString("M/dd")

Adding to what deceze said above. This is a parse error, so in order to debug a parse error, create a new file in the root named debugSyntax.php. Put this in it:

<?php

///////    SYNTAX ERROR CHECK    ////////////
error_reporting(E_ALL);
ini_set('display_errors','On');

//replace "pageToTest.php" with the file path that you want to test. 
include('pageToTest.php'); 

?>

Run the debugSyntax.php page and it will display parse errors from the page that you chose to test.

Be carreful of the know bug with SwitchCompat

It's a bug with corrupt file in drawable-hdpi on AppCompat https://code.google.com/p/android/issues/detail?id=78262

To fix it, juste override it with this 2 files https://github.com/lopespm/quick-fix-switchcompat-resources Add it on your directory drawable-hdpi

XML

<android.support.v7.widget.SwitchCompat
android:id="@+id/dev_switch_show_dev_only"
android:layout_width="wrap_content"
android:layout_height="wrap_content"
/>

And nothing was necessary on Java

As an update of @Live's answer, for Qt = 5.2 there is no more need to subclass QThread, as now the sleep functions are public:

Static Public Members

• QThread * currentThread()
• Qt::HANDLE currentThreadId()
• int idealThreadCount()
• void msleep(unsigned long msecs)
• void sleep(unsigned long secs)
• void usleep(unsigned long usecs)
• void yieldCurrentThread()

I had this error before when I was executing a python3 script, after this:

sudo pip3 install requests

the problem solved, If you are using python3, give a shot.

Watch this.

The video says that you need to just add self.view.layoutIfNeeded() like the following:

UIView.animate(withDuration: 1.0, animations: {
       self.centerX.constant -= 75
       self.view.layoutIfNeeded()
}, completion: nil)

Use docker-compose and multiple Dockerfile in separate directories

Don't rename your Dockerfile to Dockerfile.db or Dockerfile.web, it may not be supported by your IDE and you will lose syntax highlighting.

As Kingsley Uchnor said, you can have multiple Dockerfile, one per directory, which represent something you want to build.

I like to have a docker folder which holds each applications and their configuration. Here's an example project folder hierarchy for a web application that has a database.

docker-compose.yml
docker
+-- web
¦   +-- Dockerfile
+-- db
    +-- Dockerfile

docker-compose.yml example:

version: '3'
services:
  web:
    # will build ./docker/web/Dockerfile
    build: ./docker/web
    ports:
     - "5000:5000"
    volumes:
     - .:/code
  db:
    # will build ./docker/db/Dockerfile
    build: ./docker/db
    ports:
      - "3306:3306"
  redis:
    # will use docker hub's redis prebuilt image from here:
    # https://hub.docker.com/_/redis/
    image: "redis:alpine"

docker-compose command line usage example:

# The following command will create and start all containers in the background
# using docker-compose.yml from current directory
docker-compose up -d

# get help
docker-compose --help

In case you need files from previous folders when building your Dockerfile

You can still use the above solution and place your Dockerfile in a directory such as docker/web/Dockerfile, all you need is to set the build context in your docker-compose.yml like this:

version: '3'
services:
  web:
    build:
      context: .
      dockerfile: ./docker/web/Dockerfile
    ports:
     - "5000:5000"
    volumes:
     - .:/code

This way, you'll be able to have things like this:

config-on-root.ini
docker-compose.yml
docker
+-- web
    +-- Dockerfile
    +-- some-other-config.ini

and a ./docker/web/Dockerfile like this:

FROM alpine:latest

COPY config-on-root.ini /
COPY docker/web/some-other-config.ini /

Here are some quick commands from tldr docker-compose. Make sure you refer to official documentation for more details.

I found a possible solution, but... I don't know if it's a good solution.

@Entity
public class Role extends Identifiable {

    @ManyToMany(cascade ={CascadeType.MERGE, CascadeType.PERSIST, CascadeType.REFRESH})
    @JoinTable(name="Role_Permission",
            joinColumns=@JoinColumn(name="Role_id"),
            inverseJoinColumns=@JoinColumn(name="Permission_id")
        )
    public List<Permission> getPermissions() {
        return permissions;
    }

    public void setPermissions(List<Permission> permissions) {
        this.permissions = permissions;
    }
}

@Entity
public class Permission extends Identifiable {

    @ManyToMany(cascade = {CascadeType.MERGE, CascadeType.PERSIST, CascadeType.REFRESH})
    @JoinTable(name="Role_Permission",
            joinColumns=@JoinColumn(name="Permission_id"),
            inverseJoinColumns=@JoinColumn(name="Role_id")
        )
    public List<Role> getRoles() {
        return roles;
    }

    public void setRoles(List<Role> roles) {
        this.roles = roles;
    }

I have tried this and it works. When you delete Role, also the relations are deleted (but not the Permission entities) and when you delete Permission, the relations with Role are deleted too (but not the Role instance). But we are mapping a unidirectional relation two times and both entities are the owner of the relation. Could this cause some problems to Hibernate? Which type of problems?

Thanks!

The code above is from another post related.

Here is how I did it using the YUI selectors. Thanks to Hank Gay's suggestion.

notes = YAHOO.util.Dom.getElementsByClassName('four','span','test');

where four = classname, span = the element type/tag name, and test = the parent id.

The first thing you should do is learn to read error messages. What does it tell you -- that you can't use two strings with the divide operator.

So, ask yourself why they are strings and how do you make them not-strings. They are strings because all input is done via strings. And the way to make then not-strings is to convert them.

One way to convert a string to an integer is to use the int function. For example:

percent = (int(pyc) / int(tpy)) * 100

Most suggestions will fail if there so much as a single leading or trailing space, which would matter if the file is being edited by hand. This would make it less susceptible in that case:

grep '^[[:blank:]]*ABB\.log[[:blank:]]*$' a.tmp

A simple while-read loop in shell would do this implicitly:

while read file
do 
  case $file in
    (ABB.log) printf "%s\n" "$file"
  esac
done < a.tmp

A clean way to download a file is:

import urllib

testfile = urllib.URLopener()
testfile.retrieve("http://randomsite.com/file.gz", "file.gz")

This downloads a file from a website and names it file.gz. This is one of my favorite solutions, from Downloading a picture via urllib and python.

This example uses the urllib library, and it will directly retrieve the file form a source.

Finally I able resolve this issue.

Do not install Android SDK with studio package, unkcheck the option when asked.

Steps to resolve:

• Download latest android sdk, so while runnning studio first time it has not to download any exta packages. Unpack at /yourAndroidSDKPath
• Uncheck option, Android SDK, while installing studio.
• Give the /yourAndroidSDKPath in studio installation when asked. It works for me.

I tried other solutions, run as Administrator and proxy setting but nothing worked.

A clean example.

<?php
    header('Content-Type: application/download');
    header('Content-Disposition: attachment; filename="example.txt"');
    header("Content-Length: " . filesize("example.txt"));

    $fp = fopen("example.txt", "r");
    fpassthru($fp);
    fclose($fp);
?>

In general, fixing corrupt objects can be pretty difficult. However, in this case, we're confident that the problem is an aborted transfer, meaning that the object is in a remote repository, so we should be able to safely remove our copy and let git get it from the remote, correctly this time.

The temporary object file, with zero size, can obviously just be removed. It's not going to do us any good. The corrupt object which refers to it, d4a0e75..., is our real problem. It can be found in .git/objects/d4/a0e75.... As I said above, it's going to be safe to remove, but just in case, back it up first.

At this point, a fresh git pull should succeed.

...assuming it was going to succeed in the first place. In this case, it appears that some local modifications prevented the attempted merge, so a stash, pull, stash pop was in order. This could happen with any merge, though, and didn't have anything to do with the corrupted object. (Unless there was some index cleanup necessary, and the stash did that in the process... but I don't believe so.)

For most controls, you set its height and width to Auto in the XAML, and it will size to fit its content.

In code, you set the width/height to double.NaN. For details, see FrameworkElement.Width, particularly the "remarks" section.

This is my code:

                for (int i = 0; i < length; i++) {_x000D_
                    if (listOfFiles[i].isFile()) {_x000D_
                        lstFile.add(new CdrFileBO(listOfFiles[i]));_x000D_

                    logger.info("Next file: " + getSeq(SEQ_START));_x000D_
                }_x000D_
_x000D_
            }_x000D_
        } catch (Exception ex) {_x000D_

Well, the above answer is correct, auto_now_add and auto_now would do it, but it would be better to make an abstract class and use it in any model where you require created_at and updated_at fields.

class TimeStampMixin(models.Model):
    created_at = models.DateTimeField(auto_now_add=True)
    updated_at = models.DateTimeField(auto_now=True)

    class Meta:
        abstract = True

Now anywhere you want to use it you can do a simple inherit and you can use timestamp in any model you make like.

class Posts(TimeStampMixin):
    name = models.CharField(max_length=50)
    ...
    ...

In this way, you can leverage object-oriented reusability, in Django DRY(don't repeat yourself)

The following command worked on Solaris :

find . -name "*zip" -type f | xargs ls -ltr | tail -1 

You can't cast an Object array to an Integer array. You have to loop through all elements of a and cast each one individually.

Object[] a = new Object[1];
Integer b=1;
a[0]=b;
Integer[] c = new Integer[a.length];
for(int i = 0; i < a.length; i++)
{
    c[i] = (Integer) a[i];
}

Edit: I believe the rationale behind this restriction is that when casting, the JVM wants to ensure type-safety at runtime. Since an array of Objects can be anything besides Integers, the JVM would have to do what the above code is doing anyway (look at each element individually). The language designers decided they didn't want the JVM to do that (I'm not sure why, but I'm sure it's a good reason).

However, you can cast a subtype array to a supertype array (e.g. Integer[] to Object[])!

LOAD DATA INFILE 'file.csv'
  INTO TABLE t1
  (column1, @dummy, column2, @dummy, column3, ...)
FIELDS TERMINATED BY ',' ENCLOSED BY '"' ESCAPED BY '"'
LINES TERMINATED BY '\r\n';

Just replace the column1, column2, etc.. with your column names, and put @dummy anwhere there's a column in the CSV you want to ignore.

For UTF 8 Conversion and Currency Symbol Export Use this:

var tableToExcel = (function() {
  var uri = 'data:application/vnd.ms-excel;base64,'
    , template = '<html xmlns:o="urn:schemas-microsoft-com:office:office" xmlns:x="urn:schemas-microsoft-com:office:excel" xmlns="http://www.w3.org/TR/REC-html40"><head><!--[if gte mso 9]><?xml version="1.0" encoding="UTF-8" standalone="yes"?><x:ExcelWorkbook><x:ExcelWorksheets><x:ExcelWorksheet><x:Name>{worksheet}</x:Name><x:WorksheetOptions><x:DisplayGridlines/></x:WorksheetOptions></x:ExcelWorksheet></x:ExcelWorksheets></x:ExcelWorkbook></xml><![endif]--></head><body><table>{table}</table></body></html>'
    , base64 = function(s) { return window.btoa(unescape(encodeURIComponent(s))) }
    , format = function(s, c) { return s.replace(/{(\w+)}/g, function(m, p) { return c[p]; }) }
  return function(table, name) {
      if (!table.nodeType) table = document.getElementById(table)
      var ctx = { worksheet: name || 'Worksheet', table: table.innerHTML }
    window.location.href = uri + base64(format(template, ctx))
  }
})()

I think VonC's answer is probably what you want, but here's a way to do a selective "git apply":

git show stash@{0}:MyFile.txt > MyFile.txt

Whenever you will face below error just follow it.

org.hibernate.HibernateException: No Hibernate Session bound to thread, and configuration does not allow creation of non-transactional one here at org.springframework.orm.hibernate3.SpringSessionContext.currentSession(SpringSessionContext.java:63)

Put a @Transactional annotation for each method of implementing classes.

It is used to find the how many rows contain data in a worksheet that contains data in the column "A". The full usage is

 lastRowIndex = ws.Cells(ws.Rows.Count, "A").End(xlUp).row

Where ws is a Worksheet object. In the questions example it was implied that the statement was inside a With block

With ws
    lastRowIndex = .Cells(.Rows.Count, "A").End(xlUp).row
End With

1. ws.Rows.Count returns the total count of rows in the worksheet (1048576 in Excel 2010).
2. .Cells(.Rows.Count, "A") returns the bottom most cell in column "A" in the worksheet

Then there is the End method. The documentation is ambiguous as to what it does.

Returns a Range object that represents the cell at the end of the region that contains the source range

Particularly it doesn't define what a "region" is. My understanding is a region is a contiguous range of non-empty cells. So the expected usage is to start from a cell in a region and find the last cell in that region in that direction from the original cell. However there are multiple exceptions for when you don't use it like that:

• If the range is multiple cells, it will use the region of rng.cells(1,1).
• If the range isn't in a region, or the range is already at the end of the region, then it will travel along the direction until it enters a region and return the first encountered cell in that region.
• If it encounters the edge of the worksheet it will return the cell on the edge of that worksheet.

So Range.End is not a trivial function.

4. .row returns the row index of that cell.

Another option is to use youtube-dl:

youtube-dl --skip-download --write-auto-sub $youtube_url

The default format is vtt and the other available format is ttml (--sub-format ttml).

--write-sub
       Write subtitle file

--write-auto-sub
       Write automatically generated subtitle file (YouTube only)

--all-subs
       Download all the available subtitles of the video

--list-subs
       List all available subtitles for the video

--sub-format FORMAT
       Subtitle format, accepts formats preference, for example: "srt" or "ass/srt/best"

--sub-lang LANGS
       Languages of the subtitles to download (optional) separated by commas, use --list-subs for available language tags

You can use ffmpeg to convert the subtitle file to another format:

ffmpeg -i input.vtt output.srt

This is what the VTT subtitles look like:

the circumstances that's brought us

You can see that each subtitle text is repeated three times. There is a new subtitle text every eighth line (3rd, 11th, 19th, and 27th).

This converts the VTT subtitles to a simpler format:

sed '1,/^$/d' *.vtt| # remove the part at the top
sed 's/<[^>]*>//g'| # remove tags
awk -F. 'NR%8==1{printf"%s ",$1}NR%8==3' # print each new subtitle text and its start time without milliseconds

This is what the output of the command above looks like:

00:00:01 ladies and gentlemen I'd like to thank
00:00:04 you for coming tonight especially at
00:00:05 such short notice
00:00:07 I'm sure mr. Irving will fill you in on
00:00:09 the circumstances that's brought us

This prints the closed captions of a video in the simplified format:

cap()(cd /tmp;rm -f -- *.vtt;youtube-dl --skip-download --write-auto-sub -- "$1";sed '1,/^$/d' -- *.vtt|sed 's/<[^>]*>//g'|awk -F. 'NR%8==1{printf"%s ",$1}NR%8==3')

The command below downloads the captions of all videos on a channel. When there is an error like Unable to extract video data, -i (--ignore-errors) causes youtube-dl to skip the video instead of exiting with an error.

youtube-dl -i --skip-download --write-auto-sub -o '%(upload_date)s.%(title)s.%(id)s.%(ext)s' https://www.youtube.com/channel/$channelid;for f in *.vtt;do sed '1,/^$/d' "$f"|sed 's/<[^>]*>//g'|awk -F. 'NR%8==1{printf"%s ",$1}NR%8==3'>"${f%.vtt}";done

Using an auxiliary Spannable Class as Android String Resources shares at the bottom of the webpage. You can approach this by creatingCharSquences and giving them a style.

But in the example they give us, is just for bold, italic, and even colorize text. I needed to wrap several styles in aCharSequence in order to set them in a TextView. So to that Class (I named it CharSequenceStyles) I just added this function.

public static CharSequence applyGroup(LinkedList<CharSequence> content){
    SpannableStringBuilder text = new SpannableStringBuilder();
    for (CharSequence item : content) {
        text.append(item);
    }
    return text;
}

And in the view I added this.

            message.push(postMessageText);
            message.push(limitDebtAmount);
            message.push(pretMessageText);
            TextView.setText(CharSequenceStyles.applyGroup(message));

I hope this help you!

I just encountered this and whilst we already had .NET 4.0 installed on the server it turns out we only had the "Client Profile" version and not the "Full" version. Installing the latter fixed the problem.

What I tend to do, and I believe this is what Google intended for developers to do too, is to still get the extras from an Intent in an Activity and then pass any extra data to fragments by instantiating them with arguments.

There's actually an example on the Android dev blog that illustrates this concept, and you'll see this in several of the API demos too. Although this specific example is given for API 3.0+ fragments, the same flow applies when using FragmentActivity and Fragment from the support library.

You first retrieve the intent extras as usual in your activity and pass them on as arguments to the fragment:

public static class DetailsActivity extends FragmentActivity {

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

        // (omitted some other stuff)

        if (savedInstanceState == null) {
            // During initial setup, plug in the details fragment.
            DetailsFragment details = new DetailsFragment();
            details.setArguments(getIntent().getExtras());
            getSupportFragmentManager().beginTransaction().add(
                    android.R.id.content, details).commit();
        }
    }
}

In stead of directly invoking the constructor, it's probably easier to use a static method that plugs the arguments into the fragment for you. Such a method is often called newInstance in the examples given by Google. There actually is a newInstance method in DetailsFragment, so I'm unsure why it isn't used in the snippet above...

Anyways, all extras provided as argument upon creating the fragment, will be available by calling getArguments(). Since this returns a Bundle, its usage is similar to that of the extras in an Activity.

public static class DetailsFragment extends Fragment {
    /**
     * Create a new instance of DetailsFragment, initialized to
     * show the text at 'index'.
     */
    public static DetailsFragment newInstance(int index) {
        DetailsFragment f = new DetailsFragment();

        // Supply index input as an argument.
        Bundle args = new Bundle();
        args.putInt("index", index);
        f.setArguments(args);

        return f;
    }

    public int getShownIndex() {
        return getArguments().getInt("index", 0);
    }

    // (other stuff omitted)

}

Here is a pitfall to avoid. In case you need to access your variable $name within a function, you need to say "global $name;" at the beginning of that function. You need to repeat this for each function in the same file.

include('front.inc');
global $name;

function foo() {
  echo $name;
}

function bar() {
  echo $name;
}

foo();
bar();

will only show errors. The correct way to do that would be:

include('front.inc');

function foo() {
  global $name;
  echo $name;
}

function bar() {
  global $name;
  echo $name;
}

foo();
bar();

To expand on Charles Duffy's answer, Nginx uses the daemon off directive to run in the foreground. If it's inconvenient to put this in the configuration file, we can specify it directly on the command line. This makes it easy to run in debug mode (foreground) and directly switch to running in production mode (background) by changing command line args.

To run in foreground:

nginx -g 'daemon off;'

To run in background:

nginx

For a class Book like this:

package books;

public class Book {

    private Integer id;
    private Integer number;
    private String name;

    public Integer getId() {
        return id;
    }

    public void setId(Integer id) {
        this.id = id;
    }

    public Integer getNumber() {
        return number;
    }

    public void setNumber(Integer number) {
        this.number = number;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    @Override
    public String toString() {
        return "book{" +
                "id=" + id +
                ", number=" + number +
                ", name='" + name + '\'' + '\n' +
                '}';
    }

        System.out.println(allBooks);

    }

Before Android 4.4

What you are trying to do is simply not possible from an app (at least not on a non-rooted/non-modified device). The message "NFC tag type not supported" is displayed by the Android system (or more specifically the NFC system service) before and instead of dispatching the tag to your app. This means that the NFC system service filters MIFARE Classic tags and never notifies any app about them. Consequently, your app can't detect MIFARE Classic tags or circumvent that popup message.

On a rooted device, you may be able to bypass the message using either

1. Xposed to modify the behavior of the NFC service, or

2. the CSC (Consumer Software Customization) feature configuration files on the system partition (see /system/csc/. The NFC system service disables the popup and dispatches MIFARE Classic tags to apps if the CSC feature <CscFeature_NFC_EnableSecurityPromptPopup> is set to any value but "mifareclassic" or "all". For instance, you could use:

   <CscFeature_NFC_EnableSecurityPromptPopup>NONE</CscFeature_NFC_EnableSecurityPromptPopup>
   

   You could add this entry to, for instance, the file "/system/csc/others.xml" (within the section <FeatureSet> ... </FeatureSet> that already exists in that file).

Since, you asked for the Galaxy S6 (the question that you linked) as well: I have tested this method on the S4 when it came out. I have not verified if this still works in the latest firmware or on other devices (e.g. the S6).

Since Android 4.4

This is pure guessing, but according to this (link no longer available), it seems that some apps (e.g. NXP TagInfo) are capable of detecting MIFARE Classic tags on affected Samsung devices since Android 4.4. This might mean that foreground apps are capable of bypassing that popup using the reader-mode API (see NfcAdapter.enableReaderMode) possibly in combination with NfcAdapter.FLAG_READER_SKIP_NDEF_CHECK.

The port you are listening to is already being listened by another process.

When I faced to this error I killed the process using Windows PowerShell (because I used Windows)

1. List itemopen the windows powershell
2. type ps and then you can get list of processes
3. find the process named node, and note the Id
4. type Stop-process <Id> I think that it is help for windows users

You can make use of the SlimScroll plugin to make a div scrollable even if it is set to overflow: hidden;(i.e. scrollbar hidden).

You can also control touch scroll as well as the scroll speed using this plugin.

Hope this helps :)

You can use codecs.

import codecs
with open("test.txt",'r') as filehandle:
    content = filehandle.read()
if content[:3] == codecs.BOM_UTF8:
    content = content[3:]
print content.decode("utf-8")

I just to solve this problem.

1. I set to null the value of list
2. I saved the object (It worked)
3. I set the new data to the object
4. I resaved the object
5. It works.!

In order to avoid such error you could use CASE + ISNUMERIC to handle scenarios when you cannot convert to int.
Change

CONVERT(INT, CONVERT(VARCHAR(12), a.value))

To

CONVERT(INT,
        CASE
        WHEN IsNumeric(CONVERT(VARCHAR(12), a.value)) = 1 THEN CONVERT(VARCHAR(12),a.value)
        ELSE 0 END) 

Basically this is saying if you cannot convert me to int assign value of 0 (in my example)

Alternatively you can look at this article about creating a custom function that will check if a.value is number: http://www.tek-tips.com/faqs.cfm?fid=6423

In java8, I would use the Instant class which is already in UTC and is convenient to work with.

import java.time.Instant;

Instant ins = Instant.now();
long ts = ins.toEpochMilli();

Instant ins2 = Instant.ofEpochMilli(ts)

Alternatively, you can use the following:

import java.time.*;

Instant ins = Instant.now(); 

OffsetDateTime odt = ins.atOffset(ZoneOffset.UTC);
ZonedDateTime zdt = ins.atZone(ZoneId.of("UTC"));

Back to Instant

Instant ins4 = Instant.from(odt);

How to access screen size or pixel density or aspect ratio in flutter ?

We can access screen size and other like pixel density, aspect ration etc. with helps of MediaQuery.

syntex : MediaQuery.of(context).size.height

if you are using windows try to pass encoding='latin1', encoding='iso-8859-1' or encoding='cp1252' example:

csv_data = pd.read_csv(csvpath,encoding='iso-8859-1')
print(print(soup.encode('iso-8859-1')))

Google actually recommends this in regards to 'CSS Optimization'. They recommend in-lining critical above-fold styles and deferring the rest(css file).

Example:

<html>
  <head>
    <style>
      .blue{color:blue;}
    </style>
    </head>
  <body>
    <div class="blue">
      Hello, world!
    </div>
  </body>
</html>
<noscript><link rel="stylesheet" href="small.css"></noscript>

See: https://developers.google.com/speed/docs/insights/OptimizeCSSDelivery

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill';

If you want to make sure the current value is indeed 203 (and not accidently increase it again) you can also add another condition:

UPDATE totals 
   SET total = total + 1
WHERE name = 'bill'
  AND total = 203;

My ~/.gradle/caches/ folder was using 14G.

After using the following solution, it went from 14G to 1.7G.

$ rm -rf ~/.gradle/caches/transforms-*
$ rm -rf ~/.gradle/caches/build-cache-*

Bonus

This command shows you in detail the used cache space

$ sudo du -ah --max-depth = 1 ~/.gradle/caches/ | sort -hr

The documentation for WAITFOR() doesn't explicitly lay out the required string format.

This will wait for 2 seconds:

WAITFOR DELAY '00:00:02';

The format is hh:mi:ss.mmm.

I have found a pretty big difference in timing when testing in my browser.

I used the following script:

WARNING: running this will freeze your browser a bit, might even crash it.

var n = 10000000, i;_x000D_
i = n;_x000D_
console.time('selector');_x000D_
while (i --> 0){_x000D_
    $("body");_x000D_
}_x000D_
_x000D_
console.timeEnd('selector');_x000D_
_x000D_
i = n;_x000D_
console.time('element');_x000D_
while (i --> 0){_x000D_
    $(document.body);_x000D_
}_x000D_
_x000D_
console.timeEnd('element');

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>

I did 10 million interactions, and those were the results (Chrome 65):

selector: 19591.97509765625ms
element: 4947.8759765625ms

Passing the element directly is around 4 times faster than passing the selector.

For Kotlin devs this is the version with comparing formatted strings approach:

val sdf = SimpleDateFormat("yyMMdd")
if (sdf.format(date1) == sdf.format(date2)) {
    // same day
}

It's not the best way, but it's short and working.

In windows 10, just exit out of current login and run this on command line

--> mysqladmin -u root password “newpassword”

where instead of root could be any user.

Postgres hasn't implemented an equivalent to INSERT OR REPLACE. From the ON CONFLICT docs (emphasis mine):

It can be either DO NOTHING, or a DO UPDATE clause specifying the exact details of the UPDATE action to be performed in case of a conflict.

Though it doesn't give you shorthand for replacement, ON CONFLICT DO UPDATE applies more generally, since it lets you set new values based on preexisting data. For example:

INSERT INTO users (id, level)
VALUES (1, 0)
ON CONFLICT (id) DO UPDATE
SET level = users.level + 1;

From a web page this cannot work since IE restricts the use of that object.

Your HTTP client disconnected.

This could have a couple of reasons:

• Responding to the request took too long, the client gave up
• You responded with something the client did not understand
• The end-user actually cancelled the request
• A network error occurred
• ... probably more

You can fairly easily emulate the behavior:

URL url = new URL("http://example.com/path/to/the/file");

int numberOfBytesToRead = 200;

byte[] buffer = new byte[numberOfBytesToRead];
int numberOfBytesRead = url.openStream().read(buffer);

I had the same issue, however DoEvents didn't help me as my data connections had background-refresh enabled. Instead, using Wayne G. Dunn's answer as a jumping-off point, I created the following solution, which works just fine for me;

Sub Refresh_All_Data_Connections()

    For Each objConnection In ThisWorkbook.Connections
        'Get current background-refresh value
        bBackground = objConnection.OLEDBConnection.BackgroundQuery

        'Temporarily disable background-refresh
        objConnection.OLEDBConnection.BackgroundQuery = False

        'Refresh this connection
        objConnection.Refresh

        'Set background-refresh value back to original value
        objConnection.OLEDBConnection.BackgroundQuery = bBackground
    Next

    MsgBox "Finished refreshing all data connections"

End Sub

The MsgBox is for testing only and can be removed once you're happy the code waits.

Also, I prefer ThisWorkbook to ActiveWorkbook as I know it will target the workbook where the code resides, just in case focus changes. Nine times out of ten this won't matter, but I like to err on the side of caution.

EDIT: Just saw your edit about using an xlConnectionTypeXMLMAP connection which does not have a BackgroundQuery option, sorry. I'll leave the above for anyone (like me) looking for a way to refresh OLEDBConnection types.

No you can't since IEnumerable is an interface.

You should be able to create an empty instance of most non-interface types which implement IEnumerable, e.g.:-

IEnumerable<object> a = new object[] { };

or

IEnumerable<object> a = new List<object>();

While other answers here work, I notice you asked for a div with content. So here's my version with extra content. JSFiddle link at the bottom.

JavaScript (with comments):

// Creating a div element
var divElement = document.createElement("Div");
divElement.id = "divID";

// Styling it
divElement.style.textAlign = "center";
divElement.style.fontWeight = "bold";
divElement.style.fontSize = "smaller";
divElement.style.paddingTop = "15px";

// Adding a paragraph to it
var paragraph = document.createElement("P");
var text = document.createTextNode("Another paragraph, yay! This one will be styled different from the rest since we styled the DIV we specifically created.");
paragraph.appendChild(text);
divElement.appendChild(paragraph);

// Adding a button, cause why not!
var button = document.createElement("Button");
var textForButton = document.createTextNode("Release the alert");
button.appendChild(textForButton);
button.addEventListener("click", function(){
    alert("Hi!");
});
divElement.appendChild(button);

// Appending the div element to body
document.getElementsByTagName("body")[0].appendChild(divElement);

HTML:

<body>
  <h1>Title</h1>
  <p>This is a paragraph. Well, kind of.</p>
</body>

CSS:

h1 { color: #333333; font-family: 'Bitter', serif; font-size: 50px; font-weight: normal; line-height: 54px; margin: 0 0 54px; }

p { color: #333333; font-family: Georgia, serif; font-size: 18px; line-height: 28px; margin: 0 0 28px; }

Note: CSS lines borrowed from Ratal Tomal

Better and quicker approach without any software to download.

• Open command prompt and follow steps mentioned below
• cd path/from/where/file/istobe/copied
• ftp (serverip or name)
• It will ask for Server(AIX) User: (username)
• It will ask for password : (password)
• cd path/where/file/istobe/copied
• pwd (to check current path)
• mput (directory name which is to be copied)

This should work.

When you run the command git checkout commit_id then HEAD detached from 13ca5593d(say commit-id) and branch will be on longer available.

Move back to previous location run the command step wise -

1. git pull origin branch_name (say master)
2. git checkout branch_name
3. git pull origin branch_name

You will be back to the previous location with an updated commit from the remote repository.

You can use an extension method.

static class Extensions
{
    public static IList<T> Clone<T>(this IList<T> listToClone) where T: ICloneable
    {
        return listToClone.Select(item => (T)item.Clone()).ToList();
    }
}

You can use .present? which comes included with ActiveSupport.

@city = @user.city.present?
# etc ...

You could even write it like this

def show
  %w(city state bio contact twitter mail).each do |attr|
    instance_variable_set "@#{attr}", @user[attr].present?
  end
end

It's worth noting that if you want to test if something is blank, you can use .blank? (this is the opposite of .present?)

Also, don't use foo == nil. Use foo.nil? instead.

  CREATE OR REPLACE PACKAGE BODY TEST AS 

   FUNCTION GET_UPS(
   TIMESPAN_IN IN VARCHAR2 DEFAULT 'MONTLHY',
   STARTING_DATE_IN DATE,
   ENDING_DATE_IN DATE
   )RETURN MEASURE_TABLE IS

    T MEASURE_TABLE;

 BEGIN

    **SELECT   MEASURE_RECORD(L4_ID , L6_ID ,L8_ID ,YEAR ,
             PERIOD,VALUE )  BULK COLLECT  INTO    T
    FROM    ...**

  ;

   RETURN T;

   END GET_UPS;

END TEST;

Mine was because Firebase SDK in Gradle file was set to a wrong number version.

I removed the Firebase debs from Gradle and re-installed them again using Firebase Assistant

With Redux if have applied the following solution, which assumes I have set an initialState in all my reducers (e.g. { user: { name, email }}). In many components I check on these nested properties, so with this fix I prevent my renders methods are broken on coupled property conditions (e.g. if state.user.email, which will throw an error user is undefined if upper mentioned solutions).

const appReducer = combineReducers({
  tabs,
  user
})

const initialState = appReducer({}, {})

const rootReducer = (state, action) => {
  if (action.type === 'LOG_OUT') {
    state = initialState
  }

  return appReducer(state, action)
}

There are many ways to include external css and js files as specified in below code but you can choose one of them, i have tested them all, they work the same.

<link rel="stylesheet" href="{{ asset('css/stylesheet.css') }}" /><!--Recommended-->
<link rel="stylesheet" href="{{ URL::asset('css/somestylesheet.css') }}" />
<link rel="stylesheet" href="{{ URL::to('css/otherstylesheet.css') }}" />
<link rel="stylesheet" href="{{ url('css/anotherstylesheet.css') }}" />

Maybe there are more ways to load it.

but keep in mind that if you are loading the css and js from other than a public folder then better to use Laravel mix.

There's a simple online tool that can do this called sqlizer.io.

You upload an XLSX file to it, enter a sheet name and cell range, and it will generate a CREATE TABLE statement and a bunch of INSERT statements to import all your data into a MySQL database.

(Disclaimer: I help run SQLizer)

For synchronizing threads I prefer using CountDownLatch which helps threads to wait until the process being performed complete. In this case, the worker class is set up with a CountDownLatch instance with a given count. A call to await method will block until the current count reaches zero due to invocations of the countDown method or the timeout set is reached. This approach allows interrupting a thread instantly without having to wait for the specified waiting time to elapse:

public class IndexProcessor implements Runnable {

    private static final Logger LOGGER = LoggerFactory.getLogger(IndexProcessor.class);

    private final CountDownLatch countdownlatch;
    public IndexProcessor(CountDownLatch countdownlatch) {
        this.countdownlatch = countdownlatch;
    }


    public void run() {
        try {
            while (!countdownlatch.await(15000, TimeUnit.MILLISECONDS)) {
                LOGGER.debug("Processing...");
            }
        } catch (InterruptedException e) {
            LOGGER.error("Exception", e);
            run = false;
        }

    }
}

When you want to finish execution of the other thread, execute countDown on the CountDownLatch and join the thread to the main thread:

public class SearchEngineContextListener implements ServletContextListener {

    private static final Logger LOGGER = LoggerFactory.getLogger(SearchEngineContextListener.class);

    private Thread thread = null;
    private IndexProcessor runnable = null;
    private CountDownLatch countdownLatch = null;

    @Override
    public void contextInitialized(ServletContextEvent event) {
        countdownLatch = new CountDownLatch(1);
        Thread thread = new Thread(new IndexProcessor(countdownLatch));
        LOGGER.debug("Starting thread: " + thread);
        thread.start();
        LOGGER.debug("Background process successfully started.");
    }

    @Override
    public void contextDestroyed(ServletContextEvent event) {
        LOGGER.debug("Stopping thread: " + thread);
        if (countdownLatch != null) 
        {
            countdownLatch.countDown();
        } 
        if (thread != null) {
            try {
                thread.join();
            } catch (InterruptedException e) {
                LOGGER.error("Exception", e);
            }
            LOGGER.debug("Thread successfully stopped.");
        } 
    }
}

Using modulus will work:

num % 1 != 0
// 23 % 1 = 0
// 23.5 % 1 = 0.5

Note that this is based on the numerical value of the number, regardless of format. It treats numerical strings containing whole numbers with a fixed decimal point the same as integers:

'10.0' % 1; // returns 0
10 % 1; // returns 0
'10.5' % 1; // returns 0.5
10.5 % 1; // returns 0.5

You could try updating the table to get rid of these characters:

UPDATE dbo.[audit]
  SET UserID = REPLACE(UserID, CHAR(0), '')
  WHERE CHARINDEX(CHAR(0), UserID) > 0;

But then you'll also need to fix whatever is putting this bad data into the table in the first place. In the meantime perhaps try:

SELECT CONVERT(INT, REPLACE(UserID, CHAR(0), ''))
  FROM dbo.[audit];

But that is not a long term solution. Fix the data (and the data type while you're at it). If you can't fix the data type immediately, then you can quickly find the culprit by adding a check constraint:

ALTER TABLE dbo.[audit]
  ADD CONSTRAINT do_not_allow_stupid_data
  CHECK (CHARINDEX(CHAR(0), UserID) = 0);

EDIT

Ok, so that is definitely a 4-digit integer followed by six instances of CHAR(0). And the workaround I posted definitely works for me:

DECLARE @foo TABLE(UserID VARCHAR(32));
INSERT @foo SELECT 0x31353831000000000000;

-- this succeeds:
SELECT CONVERT(INT, REPLACE(UserID, CHAR(0), '')) FROM @foo;

-- this fails:
SELECT CONVERT(INT, UserID) FROM @foo;

Please confirm that this code on its own (well, the first SELECT, anyway) works for you. If it does then the error you are getting is from a different non-numeric character in a different row (and if it doesn't then perhaps you have a build where a particular bug hasn't been fixed). To try and narrow it down you can take random values from the following query and then loop through the characters:

SELECT UserID, CONVERT(VARBINARY(32), UserID)
  FROM dbo.[audit]
  WHERE UserID LIKE '%[^0-9]%';

So take a random row, and then paste the output into a query like this:

DECLARE @x VARCHAR(32), @i INT;
SET @x = CONVERT(VARCHAR(32), 0x...); -- paste the value here
SET @i = 1;
WHILE @i <= LEN(@x)
BEGIN
  PRINT RTRIM(@i) + ' = ' + RTRIM(ASCII(SUBSTRING(@x, @i, 1)))
  SET @i = @i + 1;
END

This may take some trial and error before you encounter a row that fails for some other reason than CHAR(0) - since you can't really filter out the rows that contain CHAR(0) because they could contain CHAR(0) and CHAR(something else). For all we know you have values in the table like:

SELECT '15' + CHAR(9) + '23' + CHAR(0);

...which also can't be converted to an integer, whether you've replaced CHAR(0) or not.

I know you don't want to hear it, but I am really glad this is painful for people, because now they have more war stories to push back when people make very poor decisions about data types.

int num = 1;
num.ToString("0000");

After going through may posts i found the best one that really works

find $file_path -type f -name "*.txt" -mtime -1 -printf "%f\n"

This prints only the file name like abc.txt not the /path/tofolder/abc.txt

Also also play around or customize with -mtime -1

I have another solution in some cases.

store your parameter in a hidden UILabel. then add this UILabel as subview of UIButton.

when button is clicked, we can have a check on UIButton's all subviews. normally only 2 UILabel in it.

one is UIButton's title, the other is the one you just added. read that UILabel's text property, you will get the parameter.

This only apply for text parameter.

I'm using Argos reporting system as a front end and Oracle in back. I just encountered this error and it was caused by a string with a double quote at the start and a single quote at the end. Replacing the double quote with a single solved the issue.

Jano's answer is the easiest way to find it.. another way would be if you click on the scheme drop down bar -> edit scheme -> arguments tab and then add NSZombieEnabled in the Environment Variables column and YES in the value column...

data will return you a string representation of a list, but it is actually still a string. Just check the type of data with type(data). That means if you try using indexing on this string representation of a list as such data['fruits'][0], it will return you "[" as it is the first character of data['fruits']

You can do json.loads(data['fruits']) to convert it back to a Python list so that you can interact with regular list indexing. There are 2 other ways you can convert it back to a Python list suggested here

you can get the value of the respective li by using this method after click

HTML:-

<!DOCTYPE html>
<html>
<head>
    <title>show the value of li</title>
    <link rel="stylesheet"  href="pathnameofcss">
</head>
<body>

    <div id="user"></div>


    <script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
    <ul id="pageno">
    <li value="1">1</li>
    <li value="2">2</li>
    <li value="3">3</li>
    <li value="4">4</li>
    <li value="5">5</li>
    <li value="6">6</li>
    <li value="7">7</li>
    <li value="8">8</li>
    <li value="9">9</li>
    <li value="10">10</li>

    </ul>

    <script src="pathnameofjs" type="text/javascript"></script>
</body>
</html>

JS:-

$("li").click(function ()
{       
var a = $(this).attr("value");

$("#user").html(a);//here the clicked value is showing in the div name user
console.log(a);//here the clicked value is showing in the console
});

CSS:-

ul{
display: flex;
list-style-type:none;
padding: 20px;
}

li{
padding: 20px;
}

@noskio is correct... it just means that simplejson isn't found on your system and you need to install it for Python older than 2.6. one way is to use the setuptools easy_install tool. with it, you can install it as easily as: easy_install simplejson

UPDATE (Feb 2014): this is probably old news to many of you, but pip is a more modern tool that works in a similar way (i.e., pip install simplejson), only it can also uninstall apps.

URL url = new URL(yourUrl, "/api/v1/status.xml");

According to the javadocs this constructor just appends whatever resource to the end of your domain, so you would want to create 2 urls:

URL domain = new URL("http://example.com");
URL url = new URL(domain + "/files/resource.xml");

Sources: http://docs.oracle.com/javase/6/docs/api/java/net/URL.html

I have a little trick for your problem. But for that you must use javascript. If you detected that the browser is Chrome insert "dummy" options between every options. Give a new class for those "dummy" options and make them disabled. The height of "dummy" options you can define with font-size property.

CSS:

option.dummy-option-for-chrome {
  font-size:2px;
  color:transparent;
}

Script:

function prepareHtml5Selects() {

  var is_chrome = /chrome/.test( navigator.userAgent.toLowerCase() );
  if(!is_chrome) return;

  $('select > option').each(function() {
    $('<option class="dummy-option-for-chrome" disabled></option>')
     .insertBefore($(this));
  });
  $('<option class="dummy-option-for-chrome" disabled></option>')
    .insertAfter($('select > option:last-child'));
}

CATALINA_HOME vs CATALINA_BASE

If you're running multiple instances, then you need both variables, otherwise only CATALINA_HOME.

In other words: CATALINA_HOME is required and CATALINA_BASE is optional.

CATALINA_HOME represents the root of your Tomcat installation.

Optionally, Tomcat may be configured for multiple instances by defining $CATALINA_BASE for each instance. If multiple instances are not configured, $CATALINA_BASE is the same as $CATALINA_HOME.

See: Apache Tomcat 7 - Introduction

Running with separate CATALINA_HOME and CATALINA_BASE is documented in RUNNING.txt which say:

The CATALINA_HOME and CATALINA_BASE environment variables are used to specify the location of Apache Tomcat and the location of its active configuration, respectively.

You cannot configure CATALINA_HOME and CATALINA_BASE variables in the setenv script, because they are used to find that file.

For example:

(4.1) Tomcat can be started by executing one of the following commands:

  %CATALINA_HOME%\bin\startup.bat         (Windows)

  $CATALINA_HOME/bin/startup.sh           (Unix)

or

  %CATALINA_HOME%\bin\catalina.bat start  (Windows)

  $CATALINA_HOME/bin/catalina.sh start    (Unix)

Multiple Tomcat Instances

In many circumstances, it is desirable to have a single copy of a Tomcat binary distribution shared among multiple users on the same server. To make this possible, you can set the CATALINA_BASE environment variable to the directory that contains the files for your 'personal' Tomcat instance.

When running with a separate CATALINA_HOME and CATALINA_BASE, the files and directories are split as following:

In CATALINA_BASE:

• bin - Only: setenv.sh (*nix) or setenv.bat (Windows), tomcat-juli.jar
• conf - Server configuration files (including server.xml)
• lib - Libraries and classes, as explained below
• logs - Log and output files
• webapps - Automatically loaded web applications
• work - Temporary working directories for web applications
• temp - Directory used by the JVM for temporary files>

In CATALINA_HOME:

• bin - Startup and shutdown scripts
• lib - Libraries and classes, as explained below
• endorsed - Libraries that override standard "Endorsed Standards". By default it's absent.

How to check

The easiest way to check what's your CATALINA_BASE and CATALINA_HOME is by running startup.sh, for example:

$ /usr/share/tomcat7/bin/startup.sh
Using CATALINA_BASE:   /usr/share/tomcat7
Using CATALINA_HOME:   /usr/share/tomcat7

You may also check where the Tomcat files are installed, by dpkg tool as below (Debian/Ubuntu):

dpkg -L tomcat7-common

SELECT t1.ks, t1.[# Tasks], COALESCE(t2.[# Late], 0) AS [# Late]
FROM 
    (SELECT ks, COUNT(*) AS '# Tasks' FROM Table GROUP BY ks) t1
LEFT JOIN
    (SELECT ks, COUNT(*) AS '# Late' FROM Table WHERE Age > Palt GROUP BY ks) t2
ON (t1.ks = t2.ks);

break will stop the current loop (or pass an integer to tell it how many loops to break from).

continue will stop the current iteration and start the next one.

As an alternative which saves from full scanning each table twice and also gives you an easy way to tell which table had more rows with a combination of values than the other:

SELECT col1
     , col2
     -- (include all columns that you want to compare)
     , COUNT(src1) CNT1
     , COUNT(src2) CNT2
  FROM (SELECT a.col1
             , a.col2
             -- (include all columns that you want to compare)
             , 1 src1
             , TO_NUMBER(NULL) src2
          FROM tab_a a
         UNION ALL
        SELECT b.col1
             , b.col2
             -- (include all columns that you want to compare)
             , TO_NUMBER(NULL) src1
             , 2 src2
          FROM tab_b b
       )
 GROUP BY col1
        , col2
HAVING COUNT(src1) <> COUNT(src2) -- only show the combinations that don't match

Short associative function example:

public String getIcon(TipoNotificacao tipo)
{
    switch (tipo){
        case Comentou : return "fa fa-comments";
        case ConviteEnviou : return "icon-envelope";
        case ConviteAceitou : return "fa fa-bolt";
        default: return "";
    }
}

Like @Dhanushka said, omit the qualifier inside "switch" is the key.

This will return all the values matching your key valueTitle

subList.SelectMany(m => m).Where(kvp => kvp.Key == "valueTitle").Select(k => k.Value).ToList();

"use strict"; Defines that JavaScript code should be executed in "strict mode".

• The "use strict" directive was new in ECMAScript version 5.
• It is not a statement, but a literal expression, ignored by earlier versions of JavaScript.
• The purpose of "use strict" is to indicate that the code should be executed in "strict mode".
• With strict mode, you can not, for example, use undeclared variables.

All modern browsers support "use strict" except Internet Explorer 9 and lower.

Disadvantage

If a developer used a library that was in strict mode, but the developer was used to working in normal mode, they might call some actions on the library that wouldn’t work as expected.

Worse, since the developer is in normal mode, they don’t have the advantages of extra errors being thrown, so the error might fail silently.

Also, as listed above, strict mode stops you from doing certain things.

People generally think that you shouldn’t use those things in the first place, but some developers don’t like the constraint and want to use all the features of the language.

• For basic example and for reference go through :

  https://www.tutorialsteacher.com/javascript/javascript-strict

Fixed by moving the view modifiers to onPostExecute so the fixed code is :

public class Soirees extends ListActivity {
    private List<Message> messages;
    private TextView tvSorties;

    //private MyProgressDialog dialog;
    @Override
    public void onCreate(Bundle icicle) {

        super.onCreate(icicle);

        setContentView(R.layout.sorties);

        tvSorties=(TextView)findViewById(R.id.TVTitle);
        tvSorties.setText("Programme des soirées");

        new ProgressTask(Soirees.this).execute();


   }


    private class ProgressTask extends AsyncTask<String, Void, Boolean> {
        private ProgressDialog dialog;
        List<Message> titles;
        private ListActivity activity;
        //private List<Message> messages;
        public ProgressTask(ListActivity activity) {
            this.activity = activity;
            context = activity;
            dialog = new ProgressDialog(context);
        }



        /** progress dialog to show user that the backup is processing. */

        /** application context. */
        private Context context;

        protected void onPreExecute() {
            this.dialog.setMessage("Progress start");
            this.dialog.show();
        }

            @Override
        protected void onPostExecute(final Boolean success) {
                List<Message> titles = new ArrayList<Message>(messages.size());
                for (Message msg : messages){
                    titles.add(msg);
                }
                MessageListAdapter adapter = new MessageListAdapter(activity, titles);
                activity.setListAdapter(adapter);
                adapter.notifyDataSetChanged();

                if (dialog.isShowing()) {
                dialog.dismiss();
            }

            if (success) {
                Toast.makeText(context, "OK", Toast.LENGTH_LONG).show();
            } else {
                Toast.makeText(context, "Error", Toast.LENGTH_LONG).show();
            }
        }

        protected Boolean doInBackground(final String... args) {
            try{    
                BaseFeedParser parser = new BaseFeedParser();
                messages = parser.parse();


                return true;
             } catch (Exception e){
                Log.e("tag", "error", e);
                return false;
             }
          }


    }

@Vladimir, thx your code was very helpful.

I`m posting here because I didn't want to post a new question. Assuming there aren't any single character declarations in the code, you can eval() the character to cause an error and check the type of the character. Something like:

function testForLetter(character) {_x000D_
  try {_x000D_
    //Variable declarations can't start with digits or operators_x000D_
    //If no error is thrown check for dollar or underscore. Those are the only nonletter characters that are allowed as identifiers_x000D_
    eval("let " + character + ";");_x000D_
    let regExSpecial = /[^\$_]/;_x000D_
    return regExSpecial.test(character);_x000D_
  } catch (error) {_x000D_
    return false;_x000D_
  }_x000D_
}_x000D_
_x000D_
console.log(testForLetter("!")); //returns false;_x000D_
console.log(testForLetter("5")); //returns false;_x000D_
console.log(testForLetter("?")); //returns true;_x000D_
console.log(testForLetter("_")); //returns false;

Just a small tweak to Joaquin Alberto's answer can solve the style issue.Just replace the getDropDownView function in the custom adapter as below,

@Override
    public View getDropDownView(int position, View convertView, ViewGroup parent) {
        View v = super.getDropDownView(position, convertView, parent);
        TextView tv = ((TextView) v);
        tv.setText(values[position].getName());
        tv.setTextColor(Color.BLACK);
        return v;
    }

I have used the gulp-order plugin but it is not always successful as you can see by my stack overflow post gulp-order node module with merged streams. When browsing through the Gulp docs I came across the streamque module which has worked quite well for specifying order of in my case concatenation. https://github.com/gulpjs/gulp/blob/master/docs/recipes/using-multiple-sources-in-one-task.md

Example of how I used it is below

var gulp         = require('gulp');
var concat       = require('gulp-concat');
var handleErrors = require('../util/handleErrors');
var streamqueue  = require('streamqueue');

gulp.task('scripts', function() {
    return streamqueue({ objectMode: true },
        gulp.src('./public/angular/config/*.js'),
        gulp.src('./public/angular/services/**/*.js'),
        gulp.src('./public/angular/modules/**/*.js'),
        gulp.src('./public/angular/primitives/**/*.js'),
        gulp.src('./public/js/**/*.js')
    )
        .pipe(concat('app.js'))
        .pipe(gulp.dest('./public/build/js'))
        .on('error', handleErrors);
});

We created a new 'runserver' management command which is a thin wrapper around the standard one but changes the default port. Roughly, you create management/commands/runserver.py and put in something like this:

# Override the value of the constant coded into django...
import django.core.management.commands.runserver as runserver
runserver.DEFAULT_PORT="8001"

# ...print out a warning...
# (This gets output twice because runserver fires up two threads (one for autoreload).
#  We're living with it for now :-)
import os
dir_path = os.path.splitext(os.path.relpath(__file__))[0]
python_path = dir_path.replace(os.sep, ".")
print "Using %s with default port %s" % (python_path, runserver.DEFAULT_PORT)

# ...and then just import its standard Command class.
# Then manage.py runserver behaves normally in all other regards.
from django.core.management.commands.runserver import Command

As described here http://developer.android.com/reference/java/util/regex/Pattern.html

Patterns are compiled regular expressions. In many cases, convenience methods such as String.matches, String.replaceAll and String.split will be preferable, but if you need to do a lot of work with the same regular expression, it may be more efficient to compile it once and reuse it. The Pattern class and its companion, Matcher, also offer more functionality than the small amount exposed by String.

public class RegularExpressionTest {

public static void main(String[] args) {
    System.out.println("String is = "+getOnlyStrings("!&(*^*(^(+one(&(^()(*)(*&^%$#@!#$%^&*()("));
    System.out.println("Number is = "+getOnlyDigits("&(*^*(^(+91-&*9hi-639-0097(&(^("));
}

 public static String getOnlyDigits(String s) {
    Pattern pattern = Pattern.compile("[^0-9]");
    Matcher matcher = pattern.matcher(s);
    String number = matcher.replaceAll("");
    return number;
 }
 public static String getOnlyStrings(String s) {
    Pattern pattern = Pattern.compile("[^a-z A-Z]");
    Matcher matcher = pattern.matcher(s);
    String number = matcher.replaceAll("");
    return number;
 }
}

Result

String is = one
Number is = 9196390097

Basically you shouldn't do exact comparisons, you should do something like this:

double a = 1.000001;
double b = 0.000001;
double c = a-b;
if (Math.abs(c-1.0) <= 0.000001) {...}

I agree John M has best answer to OP's question. Thought not explictly stated, the apparent purpose is to get a selected file name, whereas other answers return either counts or lists. I would add, however, that the msofiledialogfilepicker might be a better option in this case. ie:

Dim f As object
Set f = Application.FileDialog(msoFileDialogFilePicker)
dim varfile as variant 
f.show
with f
    .allowmultiselect = false
     for each varfile in .selecteditems
        msgbox varfile
     next varfile
end with

Note: the value of varfile will remain the same since multiselect is false (only one item is ever selected). I used its value outside the loop with equal success. It's probably better practice to do it as John M did, however. Also, the folder picker can be used to get a selected folder. I always prefer late binding, but I think the object is native to the default access library, so it may not be necessary here

NEVER DELETE apply plugin: 'com.google.gms.google-services' from the gradle. Sometimes you are using com.google.gms:google-services:3.1.0 , without apply plugin: 'com.google.gms.google-services' your gradle build successfully. BUT IT IS COMPLETELY WRONG !!!! This error comes due to google-service.json file is not at the correct location. Go to your PROJECT TAB at left side above. If you display it as ANDROID make it PROJECT then check your google-service.json file is at this location. EXPAND app then see google-service.json file below the build.gradle. IF NOT PLACE IT THERE BY RIGHT CLICK ON THE app .

I would say technically it might not be an HTTP failure, since the resource was (presumably) validly specified, the user was authenticated, and there was no operational failure (however even the spec does include some reserved codes like 402 Payment Required which aren't strictly speaking HTTP-related either, though it might be advisable to have that at the protocol level so that any device can recognize the condition).

If that's actually the case, I would add a status field to the response with application errors, like

<status><code>4</code><message>Date range is invalid</message></status>

Try it:

<input type="button" value="Dont show this again! " onClick="fbLikeDump();WriteCookie();" />

Or also

<script>
function clickEvent(){
    fbLikeDump();
    WriteCookie();
}
</script>
<input type="button" value="Dont show this again! " onClick="clickEvent();" />

As a general rule, you can use Database_Default collation so you don't need to figure out which one to use. However, I strongly suggest reading Simons Liew's excellent article Understanding the COLLATE DATABASE_DEFAULT clause in SQL Server

SELECT *
  FROM [FAEB].[dbo].[ExportaComisiones] AS f
  JOIN [zCredifiel].[dbo].[optPerson] AS p
  ON (p.vTreasuryId = f.RFC) COLLATE Database_Default 

For nice & readable results, use this:

function printVar($var) {
    echo '<pre>';
    var_dump($var); 
    echo '</pre>';
}

The above function will preserve the original formatting, making it (more)readable in a web browser.

Dictionaries are unordered in Python versions up to and including Python 3.6. If you do not care about the order of the entries and want to access the keys or values by index anyway, you can use d.keys()[i] and d.values()[i] or d.items()[i]. (Note that these methods create a list of all keys, values or items in Python 2.x. So if you need them more then once, store the list in a variable to improve performance.)

If you do care about the order of the entries, starting with Python 2.7 you can use collections.OrderedDict. Or use a list of pairs

l = [("blue", "5"), ("red", "6"), ("yellow", "8")]

if you don't need access by key. (Why are your numbers strings by the way?)

In Python 3.7, normal dictionaries are ordered, so you don't need to use OrderedDict anymore (but you still can – it's basically the same type). The CPython implementation of Python 3.6 already included that change, but since it's not part of the language specification, you can't rely on it in Python 3.6.

I've just downloaded SQL Developer 4.0 for OS X (10.9), it just got out of beta. I also downloaded the latest Postgres JDBC jar. On a lark I decided to install it (same method as other third party db drivers in SQL Dev), and it accepted it. Whenever I click "new connection", there is a tab now for Postgres... and clicking it shows a panel that asks for the database connection details.

The answer to this question has changed, whether or not it is supported, it seems to work. There is a "choose database" button, that if clicked, gives you a dropdown list filled with available postgres databases. You create the connection, open it, and it lists the schemas in that database. Most postgres commands seem to work, though no psql commands (\list, etc).

Those who need a single tool to connect to multiple database engines can now use SQL Developer.

UPDATE: This will not work using HTML5

Instead, check out this question for more techniques: CSS challenge, can I do this without introducing more HTML?

I used line-height:0 to create the effect in the header of my site guerilla-alumnus.com

<div class="description">
   <span>Text</span>
</div>

.description {
   border-top:1px dotted #AAAAAA;
}

.description span {
   background:white none repeat scroll 0 0;
   line-height:0;
   padding:0.1em 1.5em;
   position:relative;
}

Another good method is on http://robots.thoughtbot.com/

He uses a background image and floats to achieve a cool effect

Best approach:

function playPauseThisVideo(this_video_id) {

  var this_video = document.getElementById(this_video_id);

  if (this_video.paused) {

    console.log("VIDEO IS PAUSED");

  } else {

    console.log("VIDEO IS PLAYING");

  }

}

The only reason is that Unix historically had a convention of all human-readable text files ending in a newline. At the time, this avoided extra processing when displaying or joining text files, and avoided treating text files differently to files containing other kinds of data (eg raw binary data which isn't human-readable).

Because of this convention, many tools from that era expect the ending newline, including text editors, diffing tools, and other text processing tools. Mac OS X was built on BSD Unix, and Linux was developed to be Unix-compatible, so both operating systems have inherited the same convention, behaviour and tools.

Windows wasn't developed to be Unix-compatible, so it doesn't have the same convention, and most Windows software will deal just fine with no trailing newline.

But, since Git was developed for Linux first, and a lot of open-source software is built on Unix-compatible systems like Linux, Mac OS X, FreeBSD, etc, most open-source communities and their tools (including programming languages) continue to follow these conventions.

There are technical reasons which made sense in 1971, but in this era it's mostly convention and maintaining compatibility with existing tools.

How about this:

from pandas import *

idx = Int64Index([171, 174, 173])
df = DataFrame(index = idx, data =([1,2,3]))
print df

It gives me:

     0
171  1
174  2
173  3

Is this what you are looking for?

1. Download the latest JDBC Driver (i.e. sqljdbc4.0) from Microsoft's web site

2. Write the program as follows:

   import java.sql.*;
   class testmssql
   {
       public static void main(String args[]) throws Exception
       {
           Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
           Connection      con=DriverManager.getConnection("jdbc:sqlserver://localhost:1433;
                   databaseName=chapter16","sa","123");//repalce your databse name and user name
               Statement st=con.createStatement();
           ResultSet rs=st.executeQuery("Select * from login");//replace your table name
           while(rs.next())
           {
               String s1=rs.getString(1);
               String s2=rs.getString(2);
               System.out.println("UserID:"+s1+"Password:"+s2);
           }
           con.close();
       } 
   }
   

3. Compile the program and set the jar classpath viz: set classpath=C:\jdbc\sqljdbc4.jar;.; If you have saved your jar file in C:\jdbc after downloading and extracting.

4. Run the program and make sure your TCP/IP service is enabled. If not enabled, then follow these steps:
   1. Go to Start -> All Programs -> Microsoft SQL Server 2008 -> Configuration tools -> SQL Server Configuration Manager
   2. Expand Sql Server Network Configuration: choose your MS SQL Server Instance viz. MSQSLSERVER and enable TCP/IP.
   3. Restart your MS SQL Server Instance. This can be done also from the right click menu of Microsoft SQL Server Management Studio at the root level of your MS SQL server instance

use Values either while creating variable X or while encoding as mentioned above

# Importing the libraries
import numpy as np
import matplotlib.pyplot as plt
import pandas as pd

# Importing the dataset
# dataset = pd.read_csv('50_Startups.csv')

dataset = pd.DataFrame(np.random.rand(10, 10))
y=dataset.iloc[:, 4].values
X=dataset.iloc[:, 0:4].values

To display last 3 rows without using order by:

select * from Lms_Books_Details where Book_Code not in 
 (select top((select COUNT(*) from Lms_Books_Details ) -3 ) book_code from Lms_Books_Details) 

MaxMind GeoIP is a good service. They also have a free city-level lookup service.

When an array is passed to a method or function in PHP, it is passed by value unless you explicitly pass it by reference, like so:

function test(&$array) {
    $array['new'] = 'hey';
}

$a = $array(1,2,3);
// prints [0=>1,1=>2,2=>3]
var_dump($a);
test($a);
// prints [0=>1,1=>2,2=>3,'new'=>'hey']
var_dump($a);

In your second question, $b is not a reference to $a, but a copy of $a.

Much like the first example, you can reference $a by doing the following:

$a = array(1,2,3);
$b = &$a;
// prints [0=>1,1=>2,2=>3]

For a more in depth approach read Comparing floating point numbers. Here is the code snippet from that link:

// Usable AlmostEqual function    
bool AlmostEqual2sComplement(float A, float B, int maxUlps)    
{    
    // Make sure maxUlps is non-negative and small enough that the    
    // default NAN won't compare as equal to anything.    
    assert(maxUlps > 0 && maxUlps < 4 * 1024 * 1024);    
    int aInt = *(int*)&A;    
    // Make aInt lexicographically ordered as a twos-complement int    
    if (aInt < 0)    
        aInt = 0x80000000 - aInt;    
    // Make bInt lexicographically ordered as a twos-complement int    
    int bInt = *(int*)&B;    
    if (bInt < 0)    
        bInt = 0x80000000 - bInt;    
    int intDiff = abs(aInt - bInt);    
    if (intDiff <= maxUlps)    
        return true;    
    return false;

In macOS, i had to source it using source ~/.nvm/nvm.sh command to fix this problem.

After that, add these lines

export NVM_DIR="$HOME/.nvm"
[ -s "$NVM_DIR/nvm.sh" ] && . "$NVM_DIR/nvm.sh" # This loads nvm

onto ~/.bash_profile so that nvm will be sourced automatically upon login.

Here is how I was able to trick Excel to count expired certifications in a list. I didn't have a set date, or date range, just current date. "TODAY()" doesn't work in these for Excel 2013. It sees it as text or condition, not the date value. So these previous didn't work for me. So the word problem/scenario: How many people are expired in this list?

Use: =IFERROR(D5-TODAY(),0) Where D5 is the date to be interrogated.

Then use: =IF(J5>=1,1,0) Where J5 is the cell where the first equation is producing either a positive or negative number. This set, I have hidden on the side of the visible sheet, then I just sum the total for the number of unexpired members.

An HttpOnly cookie means that it's not available to scripting languages like JavaScript. So in JavaScript, there's absolutely no API available to get/set the HttpOnly attribute of the cookie, as that would otherwise defeat the meaning of HttpOnly.

Just set it as such on the server side using whatever server side language the server side is using. If JavaScript is absolutely necessary for this, you could consider to just let it send some (ajax) request with e.g. some specific request parameter which triggers the server side language to create an HttpOnly cookie. But, that would still make it easy for hackers to change the HttpOnly by just XSS and still have access to the cookie via JS and thus make the HttpOnly on your cookie completely useless.

if you want to add new text before or after the selected colum:

• press ctrl+v
• select columns
• press shift+i
• write your text
• press esc
• press "jj"

As long as the value of width is auto, the element can have horizontal margin, padding and border without becoming wider than its container (unless of course the sum of margin-left + border-left-width + padding-left + padding-right + border-right-width + margin-right is larger than the container). The width of its content box will be whatever is left when the margin, padding and border have been subtracted from the container’s width.

On the other hand, if you specify width:100%, the element’s total width will be 100% of its containing block plus any horizontal margin, padding and border (unless you’ve used box-sizing:border-box, in which case only margins are added to the 100% to change how its total width is calculated). This may be what you want, but most likely it isn’t.

Quoting from Import the SQLPS Module on MSDN,

The recommended way to manage SQL Server from PowerShell is to import the sqlps module into a Windows PowerShell 2.0 environment.

So, yes, you could use the Add-PSSnapin approach detailed by Christian, but it is also useful to appreciate the recommended sqlps module approach.

The simplest case assumes you have SQL Server 2012: sqlps is included in the installation so you simply load the module like any other (typically in your profile) via Import-Module sqlps. You can check if the module is available on your system with Get-Module -ListAvailable.

If you do not have SQL Server 2012, then all you need do is download the sqlps module into your modules directory so Get-Module/Import-Module will find it. Curiously, Microsoft does not make this module available for download! However, Chad Miller has kindly packaged up the requisite pieces and provided this module download. Unzip it under your ...Documents\WindowsPowerShell\Modules directory and proceed with the import.

It is interesting to note that the module approach and the snapin approach are not identical. If you load the snapins then run Get-PSSnapin (without the -Registered parameter, to show only what you have loaded) you will see the SQL snapins. If, on the other hand, you load the sqlps module Get-PSSnapin will not show the snapins loaded, so the various blog entries that test for the Invoke-Sqlcmd cmdlet by only examining snapins could be giving a false negative result.

2012.10.06 Update

For the complete story on the sqlps module vs. the sqlps mini-shell vs. SQL Server snap-ins, take a look at my two-part mini-series Practical PowerShell for SQL Server Developers and DBAs recently published on Simple-Talk.com where I have, according to one reader's comment, successfully "de-confused" the issue. :-)

If all you want is some very basic error checking, you could just check the length of the string.

              string guidStr = "";
              if( guidStr.Length == Guid.Empty.ToString().Length )
                 Guid g = new Guid( guidStr );

setVertical* helped to make vertical scrollbar always visible programmatically

scrollView.setScrollbarFadingEnabled(false);
scrollView.setVerticalScrollBarEnabled(true);
scrollView.setVerticalFadingEdgeEnabled(false);

I think it is connection issue you can get code here http://skillrow.com/sending-mail-using-smtp-and-php/

include(“smtpfile.php“);
include(“saslfile.php“); // for SASL authentication $from=”[email protected]“; //from mail id

$smtp=new smtp_class;

$smtp->host_name=”www.abc.com“; // name of host
$smtp->host_port=25;//port of host

$smtp->timeout=10;
$smtp->data_timeout=0;
$smtp->debug=1;
$smtp->html_debug=1;
$smtp->pop3_auth_host=””;
$smtp->ssl=0;
$smtp->start_tls=0;
$smtp->localhost=”localhost“;
$smtp->direct_delivery=0;

$smtp->user=”smtp username”;
$smtp->realm=””;
$smtp->password=”smtp password“;

$smtp->workstation=””;
$smtp->authentication_mechanism=””;

$mail=$smtp->SendMessage($from,array($to),array(“From:$from”,”To: $to”,”Subject: $subject”,”Date: ”.strftime(“%a, %d %b %Y %H:%M:%S %Z”)),”$message”);

if($mail){
   echo “Mail sent“;
}else{
   echo $smtp->error;
}

This is the best way to clear a multi-select or list box:

 $("#drp_assign_list option[value]").remove();

It worked for me with the following code:

ObjectMapper mapper =new ObjectMapper();    
mapper.configure(DeserializationConfig.Feature.FAIL_ON_UNKNOWN_PROPERTIES, false);

We need to add host security certificate to php.ini file. For local developement enviroment we can add cacert.pem in your local php.ini.

do phpinfo(); and file your php.ini path open and add uncomment ;curl.capath

curl.capath=path_of_your_cacert.pem

In Python 3, map returns an iterable object of type map, and not a subscriptible list, which would allow you to write map[i]. To force a list result, write

payIntList = list(map(int,payList))

However, in many cases, you can write out your code way nicer by not using indices. For example, with list comprehensions:

payIntList = [pi + 1000 for pi in payList]
for pi in payIntList:
    print(pi)

Pretty simple...you could put all of them in a cell using the concatenate function:

=CONCATENATE(A1, ", ", A2, ", ", and so on)

ListName.sort() will sort it alphabetically. You can add reverse=False/True in the brackets to reverse the order of items: ListName.sort(reverse=False)

Use C# Dictionary datastructure it good for you...

Dictionary<string, int> dict = new Dictionary<string, int>();
dict.Add("one", 1);
dict.Add("two", 2);

You can retrieve data from Ditionary in a simple way..

foreach (KeyValuePair<string, int> pair in dict)
{
    MessageBox.Show(pair.Key.ToString ()+ "  -  "  + pair.Value.ToString () );
}

Navi.

As other posters have said, you need to change the LayoutManager being used. I always preferred using a GridLayout so your code would become:

MainPanel mainPanel = new MainPanel();
JFrame mainFrame = new JFrame();
mainFrame.setLayout(new GridLayout());
mainFrame.pack();
mainFrame.setVisible(true);

GridLayout seems more conceptually correct to me when you want your panel to take up the entire screen.

Looks like some changes to SASS have made possible what you've initially tried doing:

@import "../subdir/common";

We even got this to work for some totally unrelated folder located in c:\projects\sass:

@import "../../../../../../../../../../projects/sass/common";

Just add enough ../ to be sure you'll end up at the drive root and you're good to go.

Of course, this solution is far from pretty, but I couldn't get an import from a totally different folder to work, neither using I c:\projects\sass nor setting the environment variable SASS_PATH (from: :load_paths reference) to that same value.

I had an issue and fixed it after spending 2 hours to find. My environment as below:

cocoapod 0.39.0

swift 2.x

XCode 7.3.1

Steps:

1. project path: project_name/project_name/your_bridging_header.h
2. In Swift section at Build Setting, Objective-C Bridging Header should be: project_name/your_bridging_header.h
3. In your_bridging_header.h, change all declarations from .h to #import
4. In class which is being used your_3rd_party. Declare import your_3rd_party

You can use any of the following:

\b      #A word break and will work for both spaces and end of lines.
(^|\s)  #the | means or. () is a capturing group. 


/\b(stackoverflow)\b/

Also, if you don't want to include the space in your match, you can use lookbehind/aheads.

(?<=\s|^)         #to look behind the match
(stackoverflow)   #the string you want. () optional
(?=\s|$)          #to look ahead.

List<String> l = new ArrayList<String>(listOfTopicAuthors);

Maybe simple, economic way (less signs to use)...

$array = [];

We can read in php manual :

As of PHP 5.4 you can also use the short array syntax, which replaces array() with [].

UPDATED

For python 3, you should use items() instead of iteritems()

PYTHON 2

for attr, value in k.__dict__.iteritems():
        print attr, value

PYTHON 3

for attr, value in k.__dict__.items():
        print(attr, value)

This will print

'names', [a list with names]
'tweet', [a list with tweet]

Unfortunately, the best method to approach this is to use Internet Explorer as it's a browser that is guaranteed to be on Windows based machines. This will also bring compatibility of other users which might have alternative browsers such as Firefox, Chrome, Opera..etc,

start "iexplore.exe" http://www.website.com

There begin to appear some answers that assume you want to get all <td> elements from #table. If so, the simplest cross-browser way how to do this is document.getElementById('table').getElementsByTagName('td'). This works because getElementsByTagName doesn't return only immediate children. No loops are needed.

Different browsers do this differently.

1. First open console window by right clicking on the page and selecting "Inspect Element", or by hitting F12.

2. In the console, type...

   • Firefox

     functionName.toSource()
     

   • Chrome

     functionName
     

For a good quality x264 encoding of 1060i, done by a computer, not a mobile device, not in real time, you could use a bitrate at about 5 MBps. That means 2250 MB/hour of encoded material. Recommend you deinterlace the footage and compress as progressive.

There was an issue in coredns pod, I deleted such pod by

kubectl delete pod -n=kube-system coredns-fb8b8dccf-8ggcf

Its pod will restart automatically.

Two possibilities :

via script task and builtin javascript engine (if using jdk >= 1.6)

<project>

 <property name="propA" value="This is a value"/>

 <script language="javascript">
  project.setProperty('propB', project.getProperty('propA').
   replace(" ", "_"));
 </script>
 <echo>$${propB} => ${propB}</echo>

</project>

or using Ant addon Flaka

<project xmlns:fl="antlib:it.haefelinger.flaka">

 <property name="propA" value="This is a value"/>

 <fl:let> propB := replace('${propA}', '_', ' ')</fl:let>

 <echo>$${propB} => ${propB}</echo>

</project>

to overwrite exisiting property propA simply replace propB with propA

I know this question is 4 years old, but I have a couple different options:

Option 1: Using tar --to-command grep

The following line will look in example.tgz for PATTERN. This is similar to @Jester's example, but I couldn't get his pattern matching to work.

tar xzf example.tgz --to-command 'grep --label="$TAR_FILENAME" -H PATTERN ; true'

Option 2: Using tar -tzf

The second option is using tar -tzf to list the files, then go through them with grep. You can create a function to use it over and over:

targrep () {
    for i in $(tar -tzf "$1"); do
        results=$(tar -Oxzf "$1" "$i" | grep --label="$i" -H "$2")
        echo "$results"
    done
}

Usage:

targrep example.tar.gz "pattern"

You should start using jQuery or some other js lib. It's way easier than js, and you can use it as a shorthand for most js instead of actually long, drawn out js.

Simply put <script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script> (or whatever the latest google cdn is https://developers.google.com/speed/libraries/devguide#jquery) in your <head>.

Then, inside your event code (much easier if you use jQuery: $.click() for buttons, $.change() for checkboxes, selects, radios...), put the code from your second link looking more like

$('#theIDofTheButtonThatTriggersThisAnimation').click(function(){
    $('#theIDofTheElementYouWantToSmoothlyScroll').animate({
        scrollTop: 0
    }, 2000);
});

However, if you're trying to do animations, I recommend you look into some basic css properties like position:absolute and position:relative to keep from going crazy.

I'm still not quite sure what's going on in your code because it's very non-standard relative to how things are done now with css & jQuery. I'd break it down into something simple to learn the general concept.

For your example, you should build off of my animation example, how I learned: https://stackoverflow.com/a/12906254/1382306

I think you're trying to move your text up and down based upon a $.click(). In the fiddle in my answer, it slides left and right. You can easily reformat up and down by using the css top property instead of left.

Once you figure out how to move the entire div up and down, you can make a relative container to hold all of the content absolute divs and manipulate all content divs with a loop by setting their tops. Here's a quick primer on absolute in relative: http://css-tricks.com/absolute-positioning-inside-relative-positioning/

All of my animations have relative containers and absolute content. It's how I made a custom gridview plugin that can instantly zip through an entire database.

Also, there really is no overuse of divs when it comes to animating. Trying to make 1 div do everything is a nightmare.

Try to see if you can reformat my fiddle into a vertical slide out. Once you've done that, research absolute in relative a little. If you have any more problems, just ask another question.

Change your thinking to these philosophies, and you'll start flying through this type of coding.

File file = context.getFilesDir(); 
file.mkdir();
String[] array = filePath.split("/"); 
for(int t = 0; t < array.length - 1; t++) {
    file = new File(file, array[t]); 
    file.mkdir();
}
File f = new File(file,array[array.length- 1]); 
RandomAccessFileOutputStream rvalue = 
    new RandomAccessFileOutputStream(f, append);

django-fullurl

If you're trying to do this in a Django template, I've released a tiny PyPI package django-fullurl to let you replace url and static template tags with fullurl and fullstatic, like this:

{% load fullurl %}

Absolute URL is: {% fullurl "foo:bar" %}

Another absolute URL is: {% fullstatic "kitten.jpg" %}

These badges should hopefully stay up-to-date automatically:

In a view, you can of course use request.build_absolute_uri instead.

you can use TextBlock control and assign the text property.

If I have understood your question correctly you want to display one particular cell of your populated datatable? This what I used to display the given cell in my DataGrid.

$(document).ready(function(){
    $('#colorselector').on('change', function() {
      if ( this.value == 'red')

        $("#divid").show();
      }
      else
      {
        $("#divid").hide();
      }
    });
});
</script>

Do like this for every value

"[1-9][0-9]*|0"

I'd just use "[0-9]+" to represent positive whole numbers.

I'm LATE to the party, but I had to solve this recently, figured I'd share the wealth.

const url = window.location.origin + window.location.pathname
//http://example.com/somedir/somefile/

window.location.origin will give you the base url, in our test case: http://example.com

window.location.pathname will give you the route path (after the base url), in our test case /somedir/somefile

SOLUTION 2

You can simply do the following to get rid of the query parameters.

const url = window.location.href.split('?')[0]

It is not possible to directly make a 3d surface using your data. I would recommend you to build an interpolation model using some tools like pykridge. The process will include three steps:

1. Train an interpolation model using pykridge
2. Build a grid from X and Y using meshgrid
3. Interpolate values for Z

Having created your grid and the corresponding Z values, now you're ready to go with plot_surface. Note that depending on the size of your data, the meshgrid function can run for a while. The workaround is to create evenly spaced samples using np.linspace for X and Y axes, then apply interpolation to infer the necessary Z values. If so, the interpolated values might different from the original Z because X and Y have changed.

Take a look at the DateDiff() function.

-- DATEDIFF ( datepart , startdate , enddate )

-- Example usage
SELECT DATEDIFF(DAY, GETDATE(), GETDATE() + 1) AS DayDiff
SELECT DATEDIFF(MINUTE, GETDATE(), GETDATE() + 1) AS MinuteDiff
SELECT DATEDIFF(SECOND, GETDATE(), GETDATE() + 1) AS SecondDiff
SELECT DATEDIFF(WEEK, GETDATE(), GETDATE() + 1) AS WeekDiff
SELECT DATEDIFF(HOUR, GETDATE(), GETDATE() + 1) AS HourDiff
...

You can see it in action / play with it here

AngularJS form elements look for the required attribute to perform validation functions. ng-required allows you to set the required attribute depending on a boolean test (for instance, only require field B - say, a student number - if the field A has a certain value - if you selected "student" as a choice)

As an example, <input required> and <input ng-required="true"> are essentially the same thing

If you are wondering why this is this way, (and not just make <input required="true"> or <input required="false">), it is due to the limitations of HTML - the required attribute has no associated value - its mere presence means (as per HTML standards) that the element is required - so angular needs a way to set/unset required value (required="false" would be invalid HTML)

bool isPow2 = ((x & ~(x-1))==x)? !!x : 0;

I had this same issue, and fixed it by modifying my project's .iml file:

From:

<content url="file://$MODULE_DIR$">

  <sourceFolder url="file://$MODULE_DIR$/test" isTestSource="true" />
  <excludeFolder url="file://$MODULE_DIR$/target" />
</content>

To:

<content url="file://$MODULE_DIR$">
  <sourceFolder url="file://$MODULE_DIR$/src" isTestSource="false" />
  <sourceFolder url="file://$MODULE_DIR$/test" isTestSource="true" />
  <excludeFolder url="file://$MODULE_DIR$/target" />
</content>

You can mock out aw.Clear, either manually or using a testing framework like pymox. Manually, you'd do it using something like this:

class MyTest(TestCase):
  def testClear():
    old_clear = aw.Clear
    clear_calls = 0
    aw.Clear = lambda: clear_calls += 1
    aps.Request('nv2', aw)
    assert clear_calls == 1
    aw.Clear = old_clear

Using pymox, you'd do it like this:

class MyTest(mox.MoxTestBase):
  def testClear():
    aw = self.m.CreateMock(aps.Request)
    aw.Clear()
    self.mox.ReplayAll()
    aps.Request('nv2', aw)

You can create a new object by using the {[key]: value} syntax:

const foo = {_x000D_
  a: 'key',_x000D_
  b: 'value'_x000D_

const bar = {_x000D_
  [foo.a]: foo.b_x000D_

With the previous syntax you can now use the spread syntax {...foo, ...bar} to add a new object without mutating your old value:

const foo = {a: 1, b: 2};_x000D_
_x000D_
const bar = {...foo, ...{['c']: 3}};_x000D_
_x000D_
console.log(bar); // {a: 1, b: 2, c: 3}_x000D_
console.log(bar.c); // 3

The string is a .NET string so you can use .NET methods. In your case:

$index = "The string".IndexOf(" ")

will return 3, which is the first occurrence of space in the string. For more information see: http://msdn.microsoft.com/en-us/library/system.string.aspx

For your need try something like:

$s.SubString($s.IndexOf("_") + 1, $s.LastIndexOf(".") - $s.IndexOf("_") - 1)

Or you could use regexps:

if ($s -Match '(_)(.*)(\.)[^.]*$') {  $matches[2] }

(has to be adjusted depending on exactly what you need).

You should consider passing the -P argument in invoking Gradle.

From Gradle Documentation :

--project-prop Sets a project property of the root project, for example -Pmyprop=myvalue. See Section 14.2, “Gradle properties and system properties”.

Considering this build.gradle

task printProp << {
    println customProp
}

Invoking Gradle -PcustomProp=myProp will give this output :

$ gradle -PcustomProp=myProp printProp
:printProp
myProp

This is the way I found to pass parameters.
