The easiest way is to use JarURLConnection class :

String className = getClass().getSimpleName() + ".class";
String classPath = getClass().getResource(className).toString();
if (!classPath.startsWith("jar")) {
    return DEFAULT_PROPERTY_VALUE;
}

URL url = new URL(classPath);
JarURLConnection jarConnection = (JarURLConnection) url.openConnection();
Manifest manifest = jarConnection.getManifest();
Attributes attributes = manifest.getMainAttributes();
return attributes.getValue(PROPERTY_NAME);

Because in some cases ...class.getProtectionDomain().getCodeSource().getLocation(); gives path with vfs:/, so this should be handled additionally.

The content of the Manifest file in a JAR file created with version 1.0 of the Java Development Kit is the following.

Manifest-Version: 1.0

All the entries are as name-value pairs. The name of a header is separated from its value by a colon. The default manifest shows that it conforms to version 1.0 of the manifest specification. The manifest can also contain information about the other files that are packaged in the archive. Exactly what file information is recorded in the manifest will depend on the intended use for the JAR file. The default manifest file makes no assumptions about what information it should record about other files, so its single line contains data only about itself. Special-Purpose Manifest Headers

Depending on the intended role of the JAR file, the default manifest may have to be modified. If the JAR file is created only for the purpose of archival, then the MANIFEST.MF file is of no purpose. Most uses of JAR files go beyond simple archiving and compression and require special information to be in the manifest file. Summarized below are brief descriptions of the headers that are required for some special-purpose JAR-file functions

Applications Bundled as JAR Files: If an application is bundled in a JAR file, the Java Virtual Machine needs to be told what the entry point to the application is. An entry point is any class with a public static void main(String[] args) method. This information is provided in the Main-Class header, which has the general form:

Main-Class: classname

The value classname is to be replaced with the application's entry point.

Download Extensions: Download extensions are JAR files that are referenced by the manifest files of other JAR files. In a typical situation, an applet will be bundled in a JAR file whose manifest references a JAR file (or several JAR files) that will serve as an extension for the purposes of that applet. Extensions may reference each other in the same way. Download extensions are specified in the Class-Path header field in the manifest file of an applet, application, or another extension. A Class-Path header might look like this, for example:

Class-Path: servlet.jar infobus.jar acme/beans.jar

With this header, the classes in the files servlet.jar, infobus.jar, and acme/beans.jar will serve as extensions for purposes of the applet or application. The URLs in the Class-Path header are given relative to the URL of the JAR file of the applet or application.

Package Sealing: A package within a JAR file can be optionally sealed, which means that all classes defined in that package must be archived in the same JAR file. A package might be sealed to ensure version consistency among the classes in your software or as a security measure. To seal a package, a Name header needs to be added for the package, followed by a Sealed header, similar to this:

Name: myCompany/myPackage/
Sealed: true

The Name header's value is the package's relative pathname. Note that it ends with a '/' to distinguish it from a filename. Any headers following a Name header, without any intervening blank lines, apply to the file or package specified in the Name header. In the above example, because the Sealed header occurs after the Name: myCompany/myPackage header, with no blank lines between, the Sealed header will be interpreted as applying (only) to the package myCompany/myPackage.

Package Versioning: The Package Versioning specification defines several manifest headers to hold versioning information. One set of such headers can be assigned to each package. The versioning headers should appear directly beneath the Name header for the package. This example shows all the versioning headers:

Name: java/util/
Specification-Title: "Java Utility Classes" 
Specification-Version: "1.2"
Specification-Vendor: "Sun Microsystems, Inc.".
Implementation-Title: "java.util" 
Implementation-Version: "build57"
Implementation-Vendor: "Sun Microsystems, Inc."

you can do it in two ways using

• Serializable

• Parcelable.

This examle will show you how to implement it with serializable

class Customer implements Serializable
{
   // properties, getter setters & constructor
}

// This is your custom object
Customer customer = new Customer(name, address, zip);

Intent intent = new Intent();
intent.setClass(SourceActivity.this, TargetActivity.this);
intent.putExtra("customer", customer);
startActivity(intent);

// Now in your TargetActivity
Bundle extras = getIntent().getExtras();
if (extras != null)
{
    Customer customer = (Customer)extras.getSerializable("customer");
    // do something with the customer
}

Now have a look at this. This link will give you a brief overview of how to implement it with Parcelable.

Look at this.. This discussion will let you know which is much better way to implement it.

Thanks.

A better way: custom template filter: https://docs.djangoproject.com/en/dev/howto/custom-template-tags/

such as get my_list[x] in templates:

in template

{% load index %}
{{ my_list|index:x }}

templatetags/index.py

from django import template
register = template.Library()

@register.filter
def index(indexable, i):
    return indexable[i]

if my_list = [['a','b','c'], ['d','e','f']], you can use {{ my_list|index:x|index:y }} in template to get my_list[x][y]

It works fine with "for"

{{ my_list|index:forloop.counter0 }}

Tested and works well ^_^

My problem was that I tried to change the image in an other thread. I did like this:

- (void)changeImage {
    backgroundImage.image = [UIImage imageNamed:@"img.png"];
}

Call with:

[self performSelectorOnMainThread : @selector(changeImage) withObject:nil waitUntilDone:NO];

In your python shell/ipython do:

from django.conf import settings

settings.configure()

"Significant" is entirely dependent on context.

If you're using reflection to create a single handler object based on some configuration file, and then spending the rest of your time running database queries, then it's insignificant. If you're creating large numbers of objects via reflection in a tight loop, then yes, it's significant.

In general, design flexibility (where needed!) should drive your use of reflection, not performance. However, to determine whether performance is an issue, you need to profile rather than get arbitrary responses from a discussion forum.

Try:

select a.* ,b.* from 
(select * from (select ROW_NUMBER() OVER(ORDER BY fc_amount desc) SrNo1, fc_amount as amount1 From entry group by fc_amount) tbl where tbl.SrNo1 = 2) a
,
(select * from (select ROW_NUMBER() OVER(ORDER BY fc_amount asc) SrNo2, fc_amount as amount2  From entry group by fc_amount) tbl where tbl.SrNo2 =2) b

Set-ExecutionPolicy Unrestricted -Scope CurrentUser

This will set the execution policy for the current user (stored in HKEY_CURRENT_USER) rather than the local machine (HKEY_LOCAL_MACHINE). This is useful if you don't have administrative control over the computer.

Try using the ToDictionary method like so:

var dict = TableObj.ToDictionary( t => t.Key, t => t.TimeStamp );

As already mentioned, this is caused by a circular dependency. What has not been mentioned is that when you're using Python typing module and you import a class only to be used to annotate Types, you can use Forward references:

When a type hint contains names that have not been defined yet, that definition may be expressed as a string literal, to be resolved later.

and remove the dependency (the import), e.g. instead of

from my_module import Tree

def func(arg: Tree):
    # code

do:

def func(arg: 'Tree'):
    # code

(note the removed import statement)

To keep record of your newly created files while resolving this issue:

If you have newly created files, you can create a patch of local changes, pull in remote merges and apply your local patch after the remote merge is complete as defined step by step below:

1. Stage your local changes. (do not commit). Staging is required to create patch of new created files (as they are still untracked)

git add .

2. Create a patch to keep record

git diff --cached > mypatch.patch

3. Discard local changes and delete new local files

git reset --hard

4. Pull changes

git pull

5. Apply your patch

git apply mypatch.patch

Git will merge changes and create .rej files for changes which are not merged.

As suggested by Anu, if you have issues applying patch, try:

git apply --reject --whitespace=fix mypatch.patch This answer git: patch does not apply talks in detail about this issue

Enjoy your continued work on your feature, and commit your local changes when done.

In Swift 3.0 :

var imageView : UIImageView
    imageView  = UIImageView(frame:CGRect(x:10, y:50, width:100, height:300));
    imageView.image = UIImage(named:"Test.jpeg")
    self.view.addSubview(imageView)

If you stream the first list and use a filter based on contains within the second...

list1.stream()
    .filter(item -> !list2.contains(item))

The next question is what code you'll add to the end of this streaming operation to further process the results... over to you.

Also, list.contains is quite slow, so you would be better with sets.

But then if you're using sets, you might find some easier operations to handle this, like removeAll

Set list1 = ...;
Set list2 = ...;
Set target = new Set();
target.addAll(list1);
target.removeAll(list2);

Given we don't know how you're going to use this, it's not really possible to advise which approach to take.

Exception code c0000005 is the code for an access violation. That means that your program is accessing (either reading or writing) a memory address to which it does not have rights. Most commonly this is caused by:

• Accessing a stale pointer. That is accessing memory that has already been deallocated. Note that such stale pointer accesses do not always result in access violations. Only if the memory manager has returned the memory to the system do you get an access violation.
• Reading off the end of an array. This is when you have an array of length N and you access elements with index >=N.

To solve the problem you'll need to do some debugging. If you are not in a position to get the fault to occur under your debugger on your development machine you should get a crash dump file and load it into your debugger. This will allow you to see where in the code the problem occurred and hopefully lead you to the solution. You'll need to have the debugging symbols associated with the executable in order to see meaningful stack traces.

I have made a function for that, you only call it in a batch program within needing to code more.

The working is basically the same as the others, as it's the best way to do it.

keystore simply stores private keys, wheras truststore stores public keys. You will want to generate a java certificate for SSL communication. You can use a keygen command in windows, this will probably be the most easy solution.

My answer is repeated with Thiru's that answered it in Mar 17 at 9:25.

It was simpler and quicker, here are his solutions:

The easy way and fast way to do this is:

 three = [sum(i) for i in zip(first,second)] # [7,9,11,13,15]

Alternatively, you can use numpy sum:

 from numpy import sum
 three = sum([first,second], axis=0) # array([7,9,11,13,15])

You need numpy!

import numpy as np
a = [1,2,3,4,5]
b = [6,7,8,9,10]
c = list(np.array(a) + np.array(b))
print c
# [7, 9, 11, 13, 15]

To make it a bit more user-friendly: After you've unpacked it, go into the directory, and run bin/pycharm.sh. Once it opens, it either offers you to create a desktop entry, or if it doesn't, you can ask it to do so by going to the Tools menu and selecting Create Desktop Entry...

Then close PyCharm, and in the future you can just click on the created menu entry. (or copy it onto your Desktop)

To answer the specifics between Run and Run in Terminal: It's essentially the same, but "Run in Terminal" actually opens a terminal window first and shows you console output of the program. Chances are you don't want that :)

(Unless you are trying to debug an application, you usually do not need to see the output of it.)

If you're using SQL Server express, change

SqlConnection conn = new SqlConnection("Server=localhost;" 
       + "Database=Database1;");

to

SqlConnection conn = new SqlConnection("Server=localhost\SQLExpress;" 
       + "Database=Database1;");

That, and hundreds more connection strings can be found at http://www.connectionstrings.com/

Read line by line, not the whole file:

for line in open(file_name, 'rb'):
    # process line here

Even better use with for automatically closing the file:

with open(file_name, 'rb') as f:
    for line in f:
        # process line here

The above will read the file object using an iterator, one line at a time.

Here is a solution using moment.js:

var a = moment('7/11/2010','M/D/YYYY');
var b = moment('12/12/2010','M/D/YYYY');
var diffDays = b.diff(a, 'days');
alert(diffDays);

I used your original input values, but you didn't specify the format so I assumed the first value was July 11th. If it was intended to be November 7th, then adjust the format to D/M/YYYY instead.

Use a Metaclass

I would recommend Method #2, but you're better off using a metaclass than a base class. Here is a sample implementation:

class Singleton(type):
    _instances = {}
    def __call__(cls, *args, **kwargs):
        if cls not in cls._instances:
            cls._instances[cls] = super(Singleton, cls).__call__(*args, **kwargs)
        return cls._instances[cls]
        
class Logger(object):
    __metaclass__ = Singleton

Or in Python3

class Logger(metaclass=Singleton):
    pass

If you want to run __init__ every time the class is called, add

        else:
            cls._instances[cls].__init__(*args, **kwargs)

to the if statement in Singleton.__call__.

A few words about metaclasses. A metaclass is the class of a class; that is, a class is an instance of its metaclass. You find the metaclass of an object in Python with type(obj). Normal new-style classes are of type type. Logger in the code above will be of type class 'your_module.Singleton', just as the (only) instance of Logger will be of type class 'your_module.Logger'. When you call logger with Logger(), Python first asks the metaclass of Logger, Singleton, what to do, allowing instance creation to be pre-empted. This process is the same as Python asking a class what to do by calling __getattr__ when you reference one of it's attributes by doing myclass.attribute.

A metaclass essentially decides what the definition of a class means and how to implement that definition. See for example http://code.activestate.com/recipes/498149/, which essentially recreates C-style structs in Python using metaclasses. The thread What are some (concrete) use-cases for metaclasses? also provides some examples, they generally seem to be related to declarative programming, especially as used in ORMs.

In this situation, if you use your Method #2, and a subclass defines a __new__ method, it will be executed every time you call SubClassOfSingleton() -- because it is responsible for calling the method that returns the stored instance. With a metaclass, it will only be called once, when the only instance is created. You want to customize what it means to call the class, which is decided by it's type.

In general, it makes sense to use a metaclass to implement a singleton. A singleton is special because is created only once, and a metaclass is the way you customize the creation of a class. Using a metaclass gives you more control in case you need to customize the singleton class definitions in other ways.

Your singletons won't need multiple inheritance (because the metaclass is not a base class), but for subclasses of the created class that use multiple inheritance, you need to make sure the singleton class is the first / leftmost one with a metaclass that redefines __call__ This is very unlikely to be an issue. The instance dict is not in the instance's namespace so it won't accidentally overwrite it.

You will also hear that the singleton pattern violates the "Single Responsibility Principle" -- each class should do only one thing. That way you don't have to worry about messing up one thing the code does if you need to change another, because they are separate and encapsulated. The metaclass implementation passes this test. The metaclass is responsible for enforcing the pattern and the created class and subclasses need not be aware that they are singletons. Method #1 fails this test, as you noted with "MyClass itself is a a function, not a class, so you cannot call class methods from it."

Python 2 and 3 Compatible Version

Writing something that works in both Python2 and 3 requires using a slightly more complicated scheme. Since metaclasses are usually subclasses of type type, it's possible to use one to dynamically create an intermediary base class at run time with it as its metaclass and then use that as the baseclass of the public Singleton base class. It's harder to explain than to do, as illustrated next:

# works in Python 2 & 3
class _Singleton(type):
    """ A metaclass that creates a Singleton base class when called. """
    _instances = {}
    def __call__(cls, *args, **kwargs):
        if cls not in cls._instances:
            cls._instances[cls] = super(_Singleton, cls).__call__(*args, **kwargs)
        return cls._instances[cls]

class Singleton(_Singleton('SingletonMeta', (object,), {})): pass

class Logger(Singleton):
    pass

An ironic aspect of this approach is that it's using subclassing to implement a metaclass. One possible advantage is that, unlike with a pure metaclass, isinstance(inst, Singleton) will return True.

Corrections

On another topic, you've probably already noticed this, but the base class implementation in your original post is wrong. _instances needs to be referenced on the class, you need to use super() or you're recursing, and __new__ is actually a static method that you have to pass the class to, not a class method, as the actual class hasn't been created yet when it is called. All of these things will be true for a metaclass implementation as well.

class Singleton(object):
  _instances = {}
  def __new__(class_, *args, **kwargs):
    if class_ not in class_._instances:
        class_._instances[class_] = super(Singleton, class_).__new__(class_, *args, **kwargs)
    return class_._instances[class_]

class MyClass(Singleton):
  pass

c = MyClass()

Decorator Returning A Class

I originally was writing a comment but it was too long, so I'll add this here. Method #4 is better than the other decorator version, but it's more code than needed for a singleton, and it's not as clear what it does.

The main problems stem from the class being it's own base class. First, isn't it weird to have a class be a subclass of a nearly identical class with the same name that exists only in its __class__ attribute? This also means that you can't define any methods that call the method of the same name on their base class with super() because they will recurse. This means your class can't customize __new__, and can't derive from any classes that need __init__ called on them.

When to use the singleton pattern

Your use case is one of the better examples of wanting to use a singleton. You say in one of the comments "To me logging has always seemed a natural candidate for Singletons." You're absolutely right.

When people say singletons are bad, the most common reason is they are implicit shared state. While with global variables and top-level module imports are explicit shared state, other objects that are passed around are generally instantiated. This is a good point, with two exceptions.

The first, and one that gets mentioned in various places, is when the singletons are constant. Use of global constants, especially enums, is widely accepted, and considered sane because no matter what, none of the users can mess them up for any other user. This is equally true for a constant singleton.

The second exception, which get mentioned less, is the opposite -- when the singleton is only a data sink, not a data source (directly or indirectly). This is why loggers feel like a "natural" use for singletons. As the various users are not changing the loggers in ways other users will care about, there is not really shared state. This negates the primary argument against the singleton pattern, and makes them a reasonable choice because of their ease of use for the task.

Here is a quote from http://googletesting.blogspot.com/2008/08/root-cause-of-singletons.html:

Now, there is one kind of Singleton which is OK. That is a singleton where all of the reachable objects are immutable. If all objects are immutable than Singleton has no global state, as everything is constant. But it is so easy to turn this kind of singleton into mutable one, it is very slippery slope. Therefore, I am against these Singletons too, not because they are bad, but because it is very easy for them to go bad. (As a side note Java enumeration are just these kind of singletons. As long as you don't put state into your enumeration you are OK, so please don't.)

The other kind of Singletons, which are semi-acceptable are those which don't effect the execution of your code, They have no "side effects". Logging is perfect example. It is loaded with Singletons and global state. It is acceptable (as in it will not hurt you) because your application does not behave any different whether or not a given logger is enabled. The information here flows one way: From your application into the logger. Even thought loggers are global state since no information flows from loggers into your application, loggers are acceptable. You should still inject your logger if you want your test to assert that something is getting logged, but in general Loggers are not harmful despite being full of state.

I created a class that has the following method:

1. Create Salt

2. Hash Input

3. Validate input

   public class CryptographyProcessor
   {
       public string CreateSalt(int size)
       {
           //Generate a cryptographic random number.
           RNGCryptoServiceProvider rng = new RNGCryptoServiceProvider();
           byte[] buff = new byte[size];
           rng.GetBytes(buff);
           return Convert.ToBase64String(buff);
       }
   
       public string GenerateHash(string input, string salt)
       { 
           byte[] bytes = Encoding.UTF8.GetBytes(input + salt);
           SHA256Managed sHA256ManagedString = new SHA256Managed();
           byte[] hash = sHA256ManagedString.ComputeHash(bytes);
           return Convert.ToBase64String(hash);
       }
   
       public bool AreEqual(string plainTextInput, string hashedInput, string salt)
       {
           string newHashedPin = GenerateHash(plainTextInput, salt);
           return newHashedPin.Equals(hashedInput); 
       }
   }
   

For showing a particular trigger in a particular schema you can try the following:

select * from information_schema.triggers where 
information_schema.triggers.trigger_name like '%trigger_name%' and 
information_schema.triggers.trigger_schema like '%data_base_name%'

Simply call list on the generator.

lst = list(gen)
lst

Be aware that this affects the generator which will not return any further items.

You also cannot directly call list in IPython, as it conflicts with a command for listing lines of code.

Tested on this file:

def gen():
    yield 1
    yield 2
    yield 3
    yield 4
    yield 5
import ipdb
ipdb.set_trace()

g1 = gen()

text = "aha" + "bebe"

mylst = range(10, 20)

which when run:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> lst = list(g1)
ipdb> lst
[1, 2, 3, 4, 5]
ipdb> q
Exiting Debugger.

General method for escaping function/variable/debugger name conflicts

There are debugger commands p and pp that will print and prettyprint any expression following them.

So you could use it as follows:

$ python code.py 
> /home/javl/sandbox/so/debug/code.py(10)<module>()
      9 
---> 10 g1 = gen()
     11 

ipdb> n
> /home/javl/sandbox/so/debug/code.py(12)<module>()
     11 
---> 12 text = "aha" + "bebe"
     13 

ipdb> p list(g1)
[1, 2, 3, 4, 5]
ipdb> c

There is also an exec command, called by prefixing your expression with !, which forces debugger to take your expression as Python one.

ipdb> !list(g1)
[]

For more details see help p, help pp and help exec when in debugger.

ipdb> help exec
(!) statement
Execute the (one-line) statement in the context of
the current stack frame.
The exclamation point can be omitted unless the first word
of the statement resembles a debugger command.
To assign to a global variable you must always prefix the
command with a 'global' command, e.g.:
(Pdb) global list_options; list_options = ['-l']

df.index[df.LastName == 'Smith']

Or

df.query('LastName == "Smith"').index

Will return all row indices where LastName is Smith

I stopped using DECODE several years ago because it is non-portable. Also, it is less flexible and less readable than a CASE/WHEN.

However, there is one neat "trick" you can do with decode because of how it deals with NULL. In decode, NULL is equal to NULL. That can be exploited to tell whether two columns are different as below.

select a, b, decode(a, b, 'true', 'false') as same
  from t;

     A       B  SAME
------  ------  -----
     1       1  true
     1       0  false
     1          false
  null    null  true  

Although you must still either explicitly compare an optional with nil or use optional binding to additionally extract its value (i.e. optionals are not implicitly converted into Boolean values), it's worth noting that Swift 2 has added the guard statement to help avoid the pyramid of doom when working with multiple optional values.

In other words, your options now include explicitly checking for nil:

if xyz != nil {
    // Do something with xyz
}

Optional binding:

if let xyz = xyz {
    // Do something with xyz
    // (Note that we can reuse the same variable name)
}

And guard statements:

guard let xyz = xyz else {
    // Handle failure and then exit this code block
    // e.g. by calling return, break, continue, or throw
    return
}

// Do something with xyz, which is now guaranteed to be non-nil

Note how ordinary optional binding can lead to greater indentation when there is more than one optional value:

if let abc = abc {
    if let xyz = xyz {
        // Do something with abc and xyz
    }        
}

You can avoid this nesting with guard statements:

guard let abc = abc else {
    // Handle failure and then exit this code block
    return
}

guard let xyz = xyz else {
    // Handle failure and then exit this code block
    return
}

// Do something with abc and xyz

On Ubuntu I just needed the postgres dev package:

sudo apt-get install postgresql-server-dev-all

*Tested in a virtualenv

There's also the QueryString module's parse() method:

var http = require('http'),
    queryString = require('querystring');

http.createServer(function (oRequest, oResponse) {

    var oQueryParams;

    // get query params as object
    if (oRequest.url.indexOf('?') >= 0) {
        oQueryParams = queryString.parse(oRequest.url.replace(/^.*\?/, ''));

        // do stuff
        console.log(oQueryParams);
    }

    oResponse.writeHead(200, {'Content-Type': 'text/plain'});
    oResponse.end('Hello world.');

}).listen(1337, '127.0.0.1');

I had this error message. The problem was that I declared a virtual destructor in the header file, but the virtual functions' body was actually not implemented.

This will get all dll files and filter ones that match a regex of your directory structure.

Get-ChildItem C:\code -Recurse -filter "*.dll" | where { $_.directory -match 'C:\\code\\myproj.\\bin\\debug'}

If you just want the path, not the object you can add | select fullname to the end like this:

Get-ChildItem C:\code -Recurse -filter "*.dll" | where { $_.directory -match 'C:\\code\\myproj.\\bin\\debug'} | select fullname

There are Python libraries that can recognize files based on their content (usually a header / magic number) and that don't rely on the file name or extension.

If you're addressing many different file types, you can use python-magic. That's just a Python binding for the well-established magic library. This has a good reputation and (small endorsement) in the limited use I've made of it, it has been solid.

There are also libraries for more specialized file types. For example, the Python standard library has the imghdr module that does the same thing just for image file types.

If you need dependency-free (pure Python) file type checking, see filetype.

$array = explode('.',$string);

Returns an array of split elements.

I got the same error in this case:

var result = Db.SystemLog
.Where(log =>
    eventTypeValues.Contains(log.EventType)
    && (
        search.Contains(log.Id.ToString())
        || log.Message.Contains(search)
        || log.PayLoad.Contains(search)
        || log.Timestamp.ToString(CultureInfo.CurrentUICulture).Contains(search)
    )
)
.OrderByDescending(log => log.Id)
.Select(r => r);

After spending way too much time debugging, I figured out that error appeared in the logic expression.

The first line search.Contains(log.Id.ToString()) does work fine, but the last line that deals with a DateTime object made it fail miserably:

|| log.Timestamp.ToString(CultureInfo.CurrentUICulture).Contains(search)

Remove the problematic line and problem solved.

I do not fully understand why, but it seems as ToString() is a LINQ expression for strings, but not for Entities. LINQ for Entities deals with database queries like SQL, and SQL has no notion of ToString(). As such, we can not throw ToString() into a .Where() clause.

But how then does the first line work? Instead of ToString(), SQL have CAST and CONVERT, so my best guess so far is that linq for entities uses that in some simple cases. DateTime objects are not always found to be so simple...

might fail working with link_directories, then add each static library like following:

target_link_libraries(foo /path_to_static_library/libbar.a)

In the standard, §2.1/1 specifies:

Physical source file characters are mapped, in an implementation-defined manner, to the basic source character set (introducing new-line characters for end-of-line indicators) if necessary.

Your compiler doesn't support that format (aka cannot map it to the basic source character set), so it cannot move into further processing stages, hence the error. It is entirely possible that your compiler support a mapping from image to basic source character set, but is not required to.

Since this mapping is implementation-defined, you'll need to look at your implementations documentation to see the file formats it supports. Typically, every major compiler vendor supports (canonically defined) text files: any file produced by a text editor, typically a series of characters.

Note that the C++ standard is based off the C standard (§1.1/2), and the C(99) standard says, in §1.2:

This International Standard does not specify
— the mechanism by which C programs are transformed for use by a data-processing system;
— the mechanism by which C programs are invoked for use by a data-processing system;
— the mechanism by which input data are transformed for use by a C program;

So, again, the treatment of source files is something you need to find in your compilers documentation.

If you need to reference a dynamically generated value you can also append query string paramters after the @URL.Action like so:

    var id = $(this).attr('id');
    var value = $(this).attr('value');
    $('#user_content').load('@Url.Action("UserDetails","User")?Param1=' + id + "&Param2=" + value);


    public ActionResult Details( int id, string value )
    {
        var model = GetFooModel();
        if (Request.IsAjaxRequest())
        {
            return PartialView( "UserDetails", model );
        }
        return View(model);
    }

I think [ ]{4} might work in the example where you need to detect 4 spaces. Same with the rest: [ ]{1}, [ ]{2} and [ ]{3}. If you want to detect an empty string in general, ^[ ]*$ will do.

You have to change the line

product userFromJSON = mapper.readValue(userDataJSON, product.class);

to

product[] userFromJSON = mapper.readValue(userDataJSON, product[].class);

since you are deserializing an array (btw: you should start your class names with upper case letters as mentioned earlier). Additionally you have to create setter methods for your fields or mark them as public in order to make this work.

Edit: You can also go with Steven Schlansker's suggestion and use

List<product> userFromJSON =
        mapper.readValue(userDataJSON, new TypeReference<List<product>>() {});

instead if you want to avoid arrays.

You may want to run it in verbose + force mode.

logrotate -vf /etc/logrotate.conf

egrep -- extended grep -- will help here

ls | egrep '\.mp4$|\.mp3$|\.exe$'

One of the differences is in short

If you want an synchronous request set the async property to false for the request. Check out the jQuery AJAX Doc

public class Global : System.Web.HttpApplication
{
    protected void Application_BeginRequest(object sender, EventArgs e)
    {
        if (Request.Url.AbsolutePath.EndsWith("/"))
        {
             Server.Transfer("~/index.aspx");
        }
    }
}

You can try the faulthandler module. Install it using pip install faulthandler and add:

import faulthandler, signal
faulthandler.register(signal.SIGUSR1)

at the beginning of your program. Then send SIGUSR1 to your process (ex: kill -USR1 42) to display the Python traceback of all threads to the standard output. Read the documentation for more options (ex: log into a file) and other ways to display the traceback.

The module is now part of Python 3.3. For Python 2, see http://faulthandler.readthedocs.org/

@Configuration  
@EnableWebMvc  
public class WebAppConfig extends WebMvcConfigurerAdapter {  

    @Override

        registry.addRedirectViewController("/", "index.html");
    }

}

My way, no Spring, used during a unit test:

URI uri = TestClass.class.getResource("/resources").toURI();
Path myPath = Paths.get(uri);
Stream<Path> walk = Files.walk(myPath, 1);
for (Iterator<Path> it = walk.iterator(); it.hasNext(); ) {
    Path filename = it.next();   
    System.out.println(filename);
}

If you do NOT use the spring-boot-starter-parent pom, then from the Spring documentation:

<plugin>
    <groupId>org.springframework.boot</groupId>
    <artifactId>spring-boot-maven-plugin</artifactId>
    <version>1.1.3.RELEASE</version>

The FileInputStream class works directly with the underlying file system. If the file in question is not physically present there, it will fail to open it. The getResourceAsStream() method works differently. It tries to locate and load the resource using the ClassLoader of the class it is called on. This enables it to find, for example, resources embedded into jar files.

I think the code below

<item name="android:actionMenuTextAppearance">@style/MyActionBar.MenuTextStyle</item> 

must be in MyAppTheme section.

When using a string-typed variable in PHP containing a date, the variable must be enclosed in single quotes:

$NEW_DATE = '1997-07-15';
$sql = "INSERT INTO tbl (NEW_DATE, ...) VALUES ('$NEW_DATE', ...)";

As of Swift 2.0, best practice is:

Add the line @testable import MyApp to the top of your tests file, where "MyApp" is the Product Module Name of your app target (viewable in your app target's build settings). That's it.

(Note that the product module name will be the same as your app target's name unless your app target's name contains spaces, which will be replaced with underscores. For example, if my app target was called "Fun Game" I'd write @testable import Fun_Game at the top of my tests.)

You might need to stop the "Web Deployment Agent Service"

Press Win+R and type services.msc

Right click on Web Deployment Agent Service and select "Stop"

Restart XAMPP

Also after double clicking "Web Deployment Agent Service" you can make the Startup type to Manual, So that "Web Deployment Agent Service" will not start automatically

Kotlin Extension Properties

No file will be create when you make a File object, it is only an interface.

To make working with files easier, there is an existing .toFile function on Uri

You can also add an extension property on File and/or Uri, to simplify usage further.

val File?.exists get() = this?.exists() ?: false
val Uri?.exists get() = File(this.toString).exists()

Then just use uri.exists or file.exists to check.

protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);
        WebView wb = new WebView(this);
        wb.loadUrl("file:///android_asset/index.html");
        setContentView(wb);
    }


keep your .html in `asset` folder

Simply put, for the first level of parentage (ancestry, inheritance, lineage, etc.) HEAD^ and HEAD~ both point to the same commit, which is (located) one parent above the HEAD (commit).

Furthermore, HEAD^ = HEAD^1 = HEAD~ = HEAD~1. But HEAD^^ != HEAD^2 != HEAD~2. Yet HEAD^^ = HEAD~2. Read on.

Beyond the first level of parentage, things get trickier, especially if the working branch/master branch has had merges (from other branches). There is also the matter of syntax with the caret, HEAD^^ = HEAD~2 (they're equivalent) BUT HEAD^^ != HEAD^2 (they're two different things entirely).

Each/the caret refers to the HEAD's first parent, which is why carets stringed together are equivalent to tilde expressions, because they refer to the first parent's (first parent's) first parents, etc., etc. based strictly on the number on connected carets or on the number following the tilde (either way, they both mean the same thing), i.e. stay with the first parent and go up x generations.

HEAD~2 (or HEAD^^) refers to the commit that is two levels of ancestry up/above the current commit (the HEAD) in the hierarchy, meaning the HEAD's grandparent commit.

HEAD^2, on the other hand, refers NOT to the first parent's second parent's commit, but simply to the second parent's commit. That is because the caret means the parent of the commit, and the number following signifies which/what parent commit is referred to (the first parent, in the case when the caret is not followed by a number [because it is shorthand for the number being 1, meaning the first parent]). Unlike the caret, the number that follows afterwards does not imply another level of hierarchy upwards, but rather it implies how many levels sideways, into the hierarchy, one needs to go find the correct parent (commit). Unlike the number in a tilde expression, it is only one parent up in the hierarchy, regardless of the number (immediately) proceeding the caret. Instead of upward, the caret's trailing number counts sideways for parents across the hierarchy [at a level of parents upwards that is equivalent to the number of consecutive carets].

So HEAD^3 is equal to the third parent of the HEAD commit (NOT the great-grandparent, which is what HEAD^^^ AND HEAD~3 would be...).

try adding lastIndex+=findStr.length() to the end of your loop, otherwise you will end up in an endless loop because once you found the substring, you are trying to find it again and again from the same last position.

$id = $access_data['Privilege']['id']; 

if(!in_array($id,$user_access_arr));

    return $this->redirect(array('controller'=>'Dashboard','action'=>'index'));

This is because you are adding your <tbody> tag before <td> in table you cannot print any data without <td>.

So for that you have to make a <div> say #header with position: fixed;

 header
 {
      position: fixed;
 }

make another <div> which will act as <tbody>

tbody
{
    overflow:scroll;
}

Now your header is fixed and the body will scroll. And the header will remain there.

Like @endeR mentioned, if internationalization is a concern, the unicode_utils gem is more than adequate.

$ gem install unicode_utils
$ irb
> require 'unicode_utils'

> UnicodeUtils.downcase("FEN BILIMLERI", :tr)
=> "fen bilimleri"

String manipulations in Ruby 2.4 are now unicode-sensitive.

The problem with your code is in your loop in Check_Circular. You are advancing through the list using n1 by going one node at a time. By reassigning n2 to n2.next.next you are advancing through it two at a time.

When you do that, n2.next.next may be null, so n2 will be null after the assignment. When the loop repeats and it checks if n2.next is not null, it throws the NPE because it can't get to next since n2 is already null.

You want to do something like what Alex posted instead.

Since the aggregates string can be longer than 4000 bytes, you can't use the LISTAGG function. You could potentially create a user-defined aggregate function that returns a CLOB rather than a VARCHAR2. There is an example of a user-defined aggregate that returns a CLOB in the original askTom discussion that Tim links to from that first discussion.

The quickest way is:

>>> import time
>>> time.strftime("%Y%m%d")

I just tried. If you execute the statement to generate your local table, the tool will accept that this column name exists. Just mark the table generation statement in your editor window and click execute.

You can use JSONP to asynchronously load service data. The JSONP request will be made during the initial page load and the results will be available before your application starts. This way you won't have to bloat your routing with redundant resolves.

You html would look like this:

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<script>

function MyService {
  this.getData = function(){
    return   MyService.data;
  }
}
MyService.setData = function(data) {
  MyService.data = data;
}

angular.module('main')
.service('MyService', MyService)

</script>
<script src="/some_data.php?jsonp=MyService.setData"></script>

Solution With Less XAML and More C#

If you define the ListView in XAML:

<ListView x:Name="listView"/>

Then you can add columns and populate it in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Add columns
    var gridView = new GridView();
    this.listView.View = gridView;
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Id", DisplayMemberBinding = new Binding("Id") });
    gridView.Columns.Add(new GridViewColumn { 
        Header = "Name", DisplayMemberBinding = new Binding("Name") });

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

Solution With More XAML and less C#

However, it's easier to define the columns in XAML (inside the ListView definition):

<ListView x:Name="listView">
    <ListView.View>
        <GridView>
            <GridViewColumn Header="Id" DisplayMemberBinding="{Binding Id}"/>
            <GridViewColumn Header="Name" DisplayMemberBinding="{Binding Name}"/>
        </GridView>
    </ListView.View>
</ListView>

And then just populate the list in C#:

public Window()
{
    // Initialize
    this.InitializeComponent();

    // Populate list
    this.listView.Items.Add(new MyItem { Id = 1, Name = "David" });
}

See definition of MyItem below.

MyItem Definition

MyItem is defined like this:

public class MyItem
{
    public int Id { get; set; }

    public string Name { get; set; }
}

I believe in Oracle it means order by column #1

That's my solution

<div class="main" style="width: 100%;">

Immutable version without array copy:

const moveInArray = (arr, fromIndex, toIndex) => {
  if (toIndex === fromIndex || toIndex >= arr.length) return arr;

  const toMove = arr[fromIndex];
  const movedForward = fromIndex < toIndex;

  return arr.reduce((res, next, index) => {
    if (index === fromIndex) return res;
    if (index === toIndex) return res.concat(
      movedForward ? [next, toMove] : [toMove, next]
    );

    return res.concat(next);
  }, []);
};

Use onmouseleave.

Or, in jQuery, use mouseleave()

It is the exact thing you are looking for. Example:

<div class="outer" onmouseleave="yourFunction()">
    <div class="inner">
    </div>
</div>

or, in jQuery:

$(".outer").mouseleave(function(){
    //your code here
});

an example is here.

( I'm simplifying this a little bit as all but cmp return a value that is both an empty string, and a numerically zero value instead of 0, and a value that is both the string '1' and the numeric value 1. These are the same values you will always get from boolean operators in Perl. You should really only be using the return values for boolean or numeric operations, in which case the difference doesn't really matter. )

You need to download the Native Development Kit.

// 2. Select a database to use 
$db_select = mysqli_select_db($connection, DB_NAME);
if (!$db_select) {
    die("Database selection failed: " . mysqli_error($connection));
}

You got the order of the arguments to mysqli_select_db() backwards. And mysqli_error() requires you to provide a connection argument. mysqli_XXX is not like mysql_XXX, these arguments are no longer optional.

Note also that with mysqli you can specify the DB in mysqli_connect():

$connection = mysqli_connect(DB_SERVER, DB_USER, DB_PASS, DB_NAME);
if (!$connection) {
  die("Database connection failed: " . mysqli_connect_error();
}

You must use mysqli_connect_error(), not mysqli_error(), to get the error from mysqli_connect(), since the latter requires you to supply a valid connection.

            }

        }
}
$( window ).resize(function() {
 var screensize= $( window ).width();
  changething(screensize);
});

If the modulus (remainder) leftover from dividing by the square root is 0, then it is a perfect square.

def is_square(num: int) -> bool:
    return num % math.sqrt(num) == 0

I checked this against a list of perfect squares going up to 1000.

If every element in b has different lengths, then you need to do something like:

int totalLength = 0;
for_every_element_in_b {
    totalLength += length_of_this_b_in_bytes;
}
return (char **)malloc(totalLength);

Just for completeness, you can use the standard library and do QString qstr = QString::fromStdString(std::to_string(42));

These are the steps to install MongoDB as Windows Service :

1. Create a log directory, e.g. C:\MongoDB\log

2. Create a db directory, e.g. C:\MongoDB\db

3. Prepare a configuration file with following lines

   dbpath=C:\MongoDB\db

   logpath=C:\MongoDB\log

   Place the configuration file with name mongod.cfg in folder "C:\MongoDB\"

4. Following command will install the Windows Service on your sc.exe create MongoDB binPath= "\"C:\MongoDB\Server\3.4\bin\mongod.exe\" --service --config=\"C:\MongoDB\mongod.cfg\" DisplayName= "MongoDB 3.4" start= "auto"

5. Once you run this command, you will get the [SC] CreateService SUCCESS

6. Run following command on Command Prompt

   net start MongoDB

Take attention on -e ssh and jenkins@localhost: in next example:

rsync -r  -e ssh --chown=jenkins:admin --exclude .git --exclude Jenkinsfile --delete ./ jenkins@localhost:/home/admin/web/xxx/public

That helped me

P.S. Today, i realized that when you change (add) jenkins user to some group, permission will apply after slave (agent) restart. And my solution (-e ssh and jenkins@localhost:) need only when you can't restart agent/server.

This is the role of the subset() function:

> dat <- data.frame(A=c(1,2),B=c(3,4),C=c(5,6),D=c(7,7),E=c(8,8),F=c(9,9)) 
> subset(dat, select=c("A", "B"))
  A B
1 1 3
2 2 4

I was able to generate

static {
    WSDL_LOCATION = null;
}

by configuring pom file to have a null for wsdlurl:

Resorting to a PivotTable might not count as using formulas only but seems more practical that most other suggestions so far:

For this specific error, I installed version 20 of Crystal Report and it solved my problem: https://www.tektutorialshub.com/crystal-reports/crystal-reports-download-for-visual-studio/#Service-Pack-16

You can also download the file alone using the following link https://www.nuget.org/api/v2/package/log4net/1.2.10 rename the file to .zip and extract it.

The JVM is caching Integer values. Hence the comparison with == only works for numbers between -128 and 127.

Refer: #Immutable_Objects_.2F_Wrapper_Class_Caching

NUMERIC(3,2) means: 3 digits in total, 2 after the decimal point. So you only have a single decimal before the decimal point.

Try NUMERIC(5,2) - three before, two after the decimal point.

As long as there are no duplicates (and trains tend to only arrive at one station at a time)...

select Train, MAX(Time),
      max(Dest) keep (DENSE_RANK LAST ORDER BY Time) max_keep
from TrainTable
GROUP BY Train;

Please note that e.which, e.keyCode and e.charCode are deprecated: https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/which

I prefer e.key:

document.querySelector("input").addEventListener("keypress", function (e) {
    var allowedChars = '0123456789.';
    function contains(stringValue, charValue) {
        return stringValue.indexOf(charValue) > -1;
    }
    var invalidKey = e.key.length === 1 && !contains(allowedChars, e.key)
            || e.key === '.' && contains(e.target.value, '.');
    invalidKey && e.preventDefault();});

This function doesn't interfere with control codes in Firefox (Backspace, Tab, etc) by checking the string length: e.key.length === 1.

It also prevents duplicate dots at the beginning and between the digits: e.key === '.' && contains(e.target.value, '.')

Unfortunately, it doesn't prevent multiple dots at the end: 234....

It seems there is no way to cope with it.

I was able to resolve this problem by cleaning my assets cache:

$ rake assets:clean

You have an extra closing } in your function.

var nav = document.getElementsByClassName('nav-coll');
for (var i = 0; i < button.length; i++) {
    nav[i].addEventListener('click',function(){
            console.log('haha');
        }        // <== remove this brace
    }, false);
};

You really should be using something like JSHint or JSLint to help find these things. These tools integrate with many editors and IDEs, or you can just paste a code fragment into the above web sites and ask for an analysis.

What you are trying to do is called a sparse checkout, and that feature was added in git 1.7.0 (Feb. 2012). The steps to do a sparse clone are as follows:

mkdir <repo>
cd <repo>
git init
git remote add -f origin <url>

This creates an empty repository with your remote, and fetches all objects but doesn't check them out. Then do:

git config core.sparseCheckout true

Now you need to define which files/folders you want to actually check out. This is done by listing them in .git/info/sparse-checkout, eg:

echo "some/dir/" >> .git/info/sparse-checkout
echo "another/sub/tree" >> .git/info/sparse-checkout

Last but not least, update your empty repo with the state from the remote:

git pull origin master

You will now have files "checked out" for some/dir and another/sub/tree on your file system (with those paths still), and no other paths present.

You might want to have a look at the extended tutorial and you should probably read the official documentation for sparse checkout.

As a function:

function git_sparse_clone() (
  rurl="$1" localdir="$2" && shift 2

  mkdir -p "$localdir"
  cd "$localdir"

  git init
  git remote add -f origin "$rurl"

  git config core.sparseCheckout true

  # Loops over remaining args
  for i; do
    echo "$i" >> .git/info/sparse-checkout
  done

  git pull origin master
)

Usage:

git_sparse_clone "http://github.com/tj/n" "./local/location" "/bin"

Note that this will still download the whole repository from the server – only the checkout is reduced in size. At the moment it is not possible to clone only a single directory. But if you don't need the history of the repository, you can at least save on bandwidth by creating a shallow clone. See udondan's answer below for information on how to combine shallow clone and sparse checkout.

As of git 2.25.0 (Jan 2020) an experimental sparse-checkout command is added in git:

git sparse-checkout init
# same as: 
# git config core.sparseCheckout true

git sparse-checkout set "A/B"
# same as:
# echo "A/B" >> .git/info/sparse-checkout

git sparse-checkout list
# same as:
# cat .git/info/sparse-checkout

You can use CSS3 transitions or maybe CSS3 animations to slide in an element.

For browser support: http://caniuse.com/

I made two quick examples just to show you how I mean.

CSS transition (on hover)

Demo One

Relevant Code

.wrapper:hover #slide {
    transition: 1s;
    left: 0;
}

In this case, Im just transitioning the position from left: -100px; to 0; with a 1s. duration. It's also possible to move the element using transform: translate();

CSS animation

Demo Two

#slide {
    position: absolute;
    left: -100px;
    width: 100px;
    height: 100px;
    background: blue;
    -webkit-animation: slide 0.5s forwards;
    -webkit-animation-delay: 2s;
    animation: slide 0.5s forwards;
    animation-delay: 2s;
}

@-webkit-keyframes slide {
    100% { left: 0; }
}

@keyframes slide {
    100% { left: 0; }
}

Same principle as above (Demo One), but the animation starts automatically after 2s, and in this case I've set animation-fill-mode to forwards, which will persist the end state, keeping the div visible when the animation ends.

Like I said, two quick example to show you how it could be done.

EDIT: For details regarding CSS Animations and Transitions see:

Animations

https://developer.mozilla.org/en-US/docs/Web/Guide/CSS/Using_CSS_animations

Transitions

Hope this helped.

This is how I solved the problem:

In main.js of the 'request' module I added one line:

Request.prototype.request = function () {
  var self = this
  self.setMaxListeners(0); // Added line

This defines unlimited listeners http://nodejs.org/docs/v0.4.7/api/events.html#emitter.setMaxListeners

In my code I set the 'maxRedirects' value explicitly:

var options = {uri:headingUri, headers:headerData, maxRedirects:100};

The easiest solution for me was upgrading the .Net Compilers via Package Manager

Install-Package Microsoft.Net.Compilers

and then changing the Web.Config lines to this

<system.codedom>
 <compilers>
  <compiler language="c#;cs;csharp" extension=".cs" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.CSharpCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:6 /nowarn:1659;1699;1701" />
  <compiler language="vb;vbs;visualbasic;vbscript" extension=".vb" type="Microsoft.CodeDom.Providers.DotNetCompilerPlatform.VBCodeProvider, Microsoft.CodeDom.Providers.DotNetCompilerPlatform, Version=1.0.0.0, Culture=neutral, PublicKeyToken=31bf3856ad364e35" warningLevel="4" compilerOptions="/langversion:14 /nowarn:41008 /define:_MYTYPE=\&quot;Web\&quot; /optionInfer+" />
 </compilers>
</system.codedom>

For me it was due to react-native version in dependency section of package.json file. It was:

"dependencies": {
"expo": "^27.0.1",
"react": "16.3.1",
"react-native": "~0.55.0"
}

I chaged it to:

"dependencies": {
"expo": "^27.0.1",
"react": "16.3.1",
"react-native": "0.52.0"
}

Now it works fine.

None of the proposed answers did work for me. (e.g. in notepad++) But

^.*?(?=\;)

did.

Just add these two lines to $(document).ready in JS as follow:

$(document).ready(function () {
 $("div.sidebar nav a").removeClass("active");
        $('nav a[href$="'+ window.location.pathname.split("?")[0] +'"]').addClass('active');
});

it is better to use the dollar sign ($) (End with)

$('nav a[href$

instead of (^) (Start with)

$('nav a[href^

because, if you use the (^) sign and you have nested URLs in the navigation menu, (e.g "/account" and "/account/roles")

It will active both of them.

You can use FusedLocationProvider

For using Fused Location Provider in your project you will have to add the google play services location dependency in our app level build.gradle file

dependencies {
   implementation fileTree(dir: 'libs', include: ['*.jar'])
   ...
   ...
   ...
   implementation 'com.google.android.gms:play-services-location:17.0.0'
}

Permissions in Manifest

Apps that use location services must request location permissions. Android offers two location permissions: ACCESS_COARSE_LOCATION and ACCESS_FINE_LOCATION.

<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"/>
<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"/>

As you may know that from Android 6.0 (Marshmallow) you must request permissions for important access in the runtime. Cause it’s a security issue where while installing an application, user may not clearly understand about an important permission of their device.

ActivityCompat.requestPermissions(
    this,
    arrayOf(Manifest.permission.ACCESS_COARSE_LOCATION, Manifest.permission.ACCESS_FINE_LOCATION),
    PERMISSION_ID
)

Then you can use the FusedLocationProvider Client to get the updated location in your desired place.

    mFusedLocationClient.lastLocation.addOnCompleteListener(this) { task ->
        var location: Location? = task.result
        if (location == null) {
            requestNewLocationData()
        } else {
            findViewById<TextView>(R.id.latTextView).text = location.latitude.toString()
            findViewById<TextView>(R.id.lonTextView).text = location.longitude.toString()
        }
    }

You can also check certain configuration like if the device has location settings on or not. You can also check the article on Detect Current Latitude & Longitude using Kotlin in Android for more functionality. If there is no cache location then it will catch the current location using:

private fun requestNewLocationData() {
    var mLocationRequest = LocationRequest()
    mLocationRequest.priority = LocationRequest.PRIORITY_HIGH_ACCURACY
    mLocationRequest.interval = 0
    mLocationRequest.fastestInterval = 0
    mLocationRequest.numUpdates = 1

    mFusedLocationClient = LocationServices.getFusedLocationProviderClient(this)
    mFusedLocationClient!!.requestLocationUpdates(
            mLocationRequest, mLocationCallback,
            Looper.myLooper()
    )
}

The expression int(float(s)) mentioned by others is the best if you want to truncate the value. If you want rounding, using int(round(float(s)) if the round algorithm matches what you want (see the round documentation), otherwise you should use Decimal and one if its rounding algorithms.

I used this code:

public static async Task<IEnumerable<TResult>> SelectAsync<TSource,TResult>(this IEnumerable<TSource> source, Func<TSource, Task<TResult>> method)
{
      return await Task.WhenAll(source.Select(async s => await method(s)));
}

like this:

var result = await sourceEnumerable.SelectAsync(async s=>await someFunction(s,other params));

Using vmin and vmax forces the range for the colors. Here's an example:

import matplotlib as m
import matplotlib.pyplot as plt
import numpy as np

cdict = {
  'red'  :  ( (0.0, 0.25, .25), (0.02, .59, .59), (1., 1., 1.)),
  'green':  ( (0.0, 0.0, 0.0), (0.02, .45, .45), (1., .97, .97)),
  'blue' :  ( (0.0, 1.0, 1.0), (0.02, .75, .75), (1., 0.45, 0.45))
}

cm = m.colors.LinearSegmentedColormap('my_colormap', cdict, 1024)

x = np.arange(0, 10, .1)
y = np.arange(0, 10, .1)
X, Y = np.meshgrid(x,y)

data = 2*( np.sin(X) + np.sin(3*Y) )

def do_plot(n, f, title):
    #plt.clf()
    plt.subplot(1, 3, n)
    plt.pcolor(X, Y, f(data), cmap=cm, vmin=-4, vmax=4)
    plt.title(title)
    plt.colorbar()

plt.figure()
do_plot(1, lambda x:x, "all")
do_plot(2, lambda x:np.clip(x, -4, 0), "<0")
do_plot(3, lambda x:np.clip(x, 0, 4), ">0")
plt.show()

Whenever we are trying to retrieve any data from another server we need two steps.

First step:

-- Server one scalar variable
DECLARE @SERVER VARCHAR(MAX)
--Oracle is the server to which we want to connect
EXEC SP_ADDLINKEDSERVER @SERVER='ORACLE'

Second step:

--DBO is the owner name to know table owner name execute (SP_HELP TABLENAME)    
SELECT * INTO DESTINATION_TABLE_NAME 
FROM ORACLE.SOURCE_DATABASENAME.DBO.SOURCE_TABLE

Remove the position: absolute; attribute in the style

export const universalBtoa = str => {
  try {
    return btoa(str);
  } catch (err) {
    return Buffer.from(str).toString('base64');
  }
};

export const universalAtob = b64Encoded => {
  try {
    return atob(b64Encoded);
  } catch (err) {
    return Buffer.from(b64Encoded, 'base64').toString();
  }
};

Python is a case-sensitive language. All Python keywords are lowercase. Use if, not If.

Also, don't put a colon after the call to print(). Also, indent the print() and exit() calls, as Python uses indentation rather than brackets to represent code blocks.

And also, proceed = "y" or "Y" won't do what you want. Use proceed = "y" and if answer.lower() == proceed:, or something similar.

There's also the fact that your program will exit as long as the input value is not the single character "y" or "Y", which contradicts the prompting of "N" for the alternate case. Instead of your else clause there, use elif answer.lower() == info_incorrect:, with info_incorrect = "n" somewhere beforehand. Then just reprompt for the response or something if the input value was something else.

I'd recommend going through the tutorial in the Python documentation if you're having this much trouble the way you're learning now. http://docs.python.org/tutorial/index.html

^{This answer is all about authorization and it is a complement of my previous answer about authentication}

^{Why another answer? I attempted to expand my previous answer by adding details on how to support JSR-250 annotations. However the original answer became the way too long and exceeded the maximum length of 30,000 characters. So I moved the whole authorization details to this answer, keeping the other answer focused on performing authentication and issuing tokens.}

Supporting role-based authorization with the @Secured annotation

Besides authentication flow shown in the other answer, role-based authorization can be supported in the REST endpoints.

Create an enumeration and define the roles according to your needs:

public enum Role {
    ROLE_1,
    ROLE_2,
    ROLE_3
}

Change the @Secured name binding annotation created before to support roles:

@NameBinding
@Retention(RUNTIME)
@Target({TYPE, METHOD})
public @interface Secured {
    Role[] value() default {};
}

And then annotate the resource classes and methods with @Secured to perform the authorization. The method annotations will override the class annotations:

@Path("/example")
@Secured({Role.ROLE_1})
public class ExampleResource {

    @GET
    @Path("{id}")
    @Produces(MediaType.APPLICATION_JSON)
    public Response myMethod(@PathParam("id") Long id) {
        // This method is not annotated with @Secured
        // But it's declared within a class annotated with @Secured({Role.ROLE_1})
        // So it only can be executed by the users who have the ROLE_1 role
        ...
    }

    @DELETE
    @Path("{id}")    
    @Produces(MediaType.APPLICATION_JSON)
    @Secured({Role.ROLE_1, Role.ROLE_2})
    public Response myOtherMethod(@PathParam("id") Long id) {
        // This method is annotated with @Secured({Role.ROLE_1, Role.ROLE_2})
        // The method annotation overrides the class annotation
        // So it only can be executed by the users who have the ROLE_1 or ROLE_2 roles
        ...
    }
}

Create a filter with the AUTHORIZATION priority, which is executed after the AUTHENTICATION priority filter defined previously.

The ResourceInfo can be used to get the resource Method and resource Class that will handle the request and then extract the @Secured annotations from them:

@Secured
@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {

    @Context
    private ResourceInfo resourceInfo;

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {

        // Get the resource class which matches with the requested URL
        // Extract the roles declared by it
        Class<?> resourceClass = resourceInfo.getResourceClass();
        List<Role> classRoles = extractRoles(resourceClass);

        // Get the resource method which matches with the requested URL
        // Extract the roles declared by it
        Method resourceMethod = resourceInfo.getResourceMethod();
        List<Role> methodRoles = extractRoles(resourceMethod);

        try {

            // Check if the user is allowed to execute the method
            // The method annotations override the class annotations
            if (methodRoles.isEmpty()) {
                checkPermissions(classRoles);
            } else {
                checkPermissions(methodRoles);
            }

        } catch (Exception e) {
            requestContext.abortWith(
                Response.status(Response.Status.FORBIDDEN).build());
        }
    }

    // Extract the roles from the annotated element
    private List<Role> extractRoles(AnnotatedElement annotatedElement) {
        if (annotatedElement == null) {
            return new ArrayList<Role>();
        } else {
            Secured secured = annotatedElement.getAnnotation(Secured.class);
            if (secured == null) {
                return new ArrayList<Role>();
            } else {
                Role[] allowedRoles = secured.value();
                return Arrays.asList(allowedRoles);
            }
        }
    }

    private void checkPermissions(List<Role> allowedRoles) throws Exception {
        // Check if the user contains one of the allowed roles
        // Throw an Exception if the user has not permission to execute the method
    }
}

If the user has no permission to execute the operation, the request is aborted with a 403 (Forbidden).

To know the user who is performing the request, see my previous answer. You can get it from the SecurityContext (which should be already set in the ContainerRequestContext) or inject it using CDI, depending on the approach you go for.

If a @Secured annotation has no roles declared, you can assume all authenticated users can access that endpoint, disregarding the roles the users have.

Supporting role-based authorization with JSR-250 annotations

Alternatively to defining the roles in the @Secured annotation as shown above, you could consider JSR-250 annotations such as @RolesAllowed, @PermitAll and @DenyAll.

JAX-RS doesn't support such annotations out-of-the-box, but it could be achieved with a filter. Here are a few considerations to keep in mind if you want to support all of them:

• @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll on the class.
• @RolesAllowed on the method takes precedence over @PermitAll on the class.
• @PermitAll on the method takes precedence over @RolesAllowed on the class.
• @DenyAll can't be attached to classes.
• @RolesAllowed on the class takes precedence over @PermitAll on the class.

So an authorization filter that checks JSR-250 annotations could be like:

@Provider
@Priority(Priorities.AUTHORIZATION)
public class AuthorizationFilter implements ContainerRequestFilter {

    @Context
    private ResourceInfo resourceInfo;

    @Override
    public void filter(ContainerRequestContext requestContext) throws IOException {

        Method method = resourceInfo.getResourceMethod();

        // @DenyAll on the method takes precedence over @RolesAllowed and @PermitAll
        if (method.isAnnotationPresent(DenyAll.class)) {
            refuseRequest();
        }

        // @RolesAllowed on the method takes precedence over @PermitAll
        RolesAllowed rolesAllowed = method.getAnnotation(RolesAllowed.class);
        if (rolesAllowed != null) {
            performAuthorization(rolesAllowed.value(), requestContext);
            return;
        }

        // @PermitAll on the method takes precedence over @RolesAllowed on the class
        if (method.isAnnotationPresent(PermitAll.class)) {
            // Do nothing
            return;
        }

        // @DenyAll can't be attached to classes

        // @RolesAllowed on the class takes precedence over @PermitAll on the class

Clustered Index - A clustered index defines the order in which data is physically stored in a table. Table data can be sorted in only way, therefore, there can be only one clustered index per table. In SQL Server, the primary key constraint automatically creates a clustered index on that particular column.

Non-Clustered Index - A non-clustered index doesn’t sort the physical data inside the table. In fact, a non-clustered index is stored at one place and table data is stored in another place. This is similar to a textbook where the book content is located in one place and the index is located in another. This allows for more than one non-clustered index per table.It is important to mention here that inside the table the data will be sorted by a clustered index. However, inside the non-clustered index data is stored in the specified order. The index contains column values on which the index is created and the address of the record that the column value belongs to.When a query is issued against a column on which the index is created, the database will first go to the index and look for the address of the corresponding row in the table. It will then go to that row address and fetch other column values. It is due to this additional step that non-clustered indexes are slower than clustered indexes

Differences between clustered and Non-clustered index

1. There can be only one clustered index per table. However, you can create multiple non-clustered indexes on a single table.
2. Clustered indexes only sort tables. Therefore, they do not consume extra storage. Non-clustered indexes are stored in a separate place from the actual table claiming more storage space.
3. Clustered indexes are faster than non-clustered indexes since they don’t involve any extra lookup step.

You can run this command for making a factory reset:

killall dropbear uhttpd; sleep 1; mtd -r erase rootfs_data

Whenever you want to redirect, send the headers:

header("Location: http://www.example.com/");

Remember you cant send data to the client before that, though.

Largely based on the accepted answer, but with a few tweaks to fit better the definitions taught in some courses:

• Key: A set of = 1 columns.
• Superkey: A key that ? a candidate key.
  • Therefore, a superkey must contain > 1 columns.
  • Minimal Super key = Candidate Key: A key that can uniquely identify each row in a table.
  • Primary Key: The chosen Candidate Key for doing that.
  • Secondary key / Alternate key: A Candidate Key not chosen for doing that.
• Search Key: A key used for locating records.
• Composite key or concatenate key: A key with > 1 columns.
  • Usually implies "composite primary key", although "composite alternate key" is also a thing.
• Sort or control key: A key used to physically sequence the stored data.
• Foreign Key A key in one table that matches the Primary Key of another table.
  • The table in which foreign key resides is called as dependent table.
  • The table to which foreign key refers is known as parent table.

Because my keyboard has an O key.
It does not have a T or an O key.

I suspect most people are similarly lazy and use O when they mean T because it's easier to type.

For now, use an EditText. Use android:inputType="number" to force it to be numeric. Convert the resulting string into an integer (e.g., Integer.parseInt(myEditText.getText().toString())).

In the future, you might consider a NumberPicker widget, once that becomes available (slated to be in Honeycomb).

For the record, general_log and slow_log were introduced in 5.1.6:

http://dev.mysql.com/doc/refman/5.1/en/log-destinations.html

5.2.1. Selecting General Query and Slow Query Log Output Destinations

As of MySQL 5.1.6, MySQL Server provides flexible control over the destination of output to the general query log and the slow query log, if those logs are enabled. Possible destinations for log entries are log files or the general_log and slow_log tables in the mysql database

You could try this:

        <script type="text/javascript">
         function newWindow(url){
                window.open(url);
            }
        </script>

And call the function

The Lazy Fetch type is by default selected by Hibernate unless you explicitly mark Eager Fetch type. To be more accurate and concise, difference can be stated as below.

FetchType.LAZY = This does not load the relationships unless you invoke it via the getter method.

FetchType.EAGER = This loads all the relationships.

Pros and Cons of these two fetch types.

Lazy initialization improves performance by avoiding unnecessary computation and reduce memory requirements.

Eager initialization takes more memory consumption and processing speed is slow.

Having said that, depends on the situation either one of these initialization can be used.

if you're looking for a simple column hide you can use the :nth-child selector as well.

#tableid tr td:nth-child(3),
#tableid tr th:nth-child(3) {
    display: none;
}

I use this with the @media tag sometimes to condense wider tables when the screen is too narrow.

Two approaches:

• When you login: you can to create a copy_my_files.bat file into your All Programs > Startup folder with this content (its a plain text document):

  • xcopy c:\folder\*.* d:\another_folder\.

  Use xcopy c:\folder\*.* d:\another_folder\. /Y to overwrite the file without any prompt.

• Everytime a folder changes: if you can to use C#, you can to create a program using FileSystemWatcher

words = "apple banana apple strawberry banana lemon"
w=words.split()
e=list(set(w))       
word_freqs = {}
for i in e:
    word_freqs[i]=w.count(i)
print(word_freqs)   

Hope this helps!

Use json_decode to transform your JSON into a PHP array. Example:

$json = '{"a":"b"}';
$array = json_decode($json, true);
echo $array['a']; // b

Just Change the google play services in gradle (module app) from 9.x.x to the lower version 8.4.0 is work for me

When you can not assume that column b comes before c you can use match to find the column number of both, min to get the lower column number and seq_len to get a sequence until this column. Then you can use this index first as a positive subset, than place the new column d and then use the sequence again as a negative subset.

i <- seq_len(min(match(c("b", "c"), colnames(x))))
data.frame(x[i], d, x[-i])
#cbind(x[i], d, x[-i]) #Alternative
#  a b  d c
#1 1 4 10 7
#2 2 5 11 8
#3 3 6 12 9

In case you know that column b comes before c you can place the new column d after b:

i <- seq_len(match("b", colnames(x)))
data.frame(x[i], d, x[-i])
#  a b  d c
#1 1 4 10 7
#2 2 5 11 8
#3 3 6 12 9

Data:

x <- data.frame(a = 1:3, b = 4:6, c = 7:9)
d <- 10:12

Your settings must be incorrect.

Go to http://www.facebook.com/developers/ and edit the application you're working on.

On the "website" tab, look for "Site URL". This should be set to your website's URL "http://yoursite.com/"

Note that if you're using subdomains, you'll also need to update "Site Domain" to be "yoursite.com"

We need to specify the INITIAL_CONTEXT_FACTORY, PROVIDER_URL, USERNAME, PASSWORD etc. of JNDI to create an InitialContext.

In a standalone application, you can specify that as below

Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY, 
    "com.sun.jndi.ldap.LdapCtxFactory");
env.put(Context.PROVIDER_URL, "ldap://ldap.wiz.com:389");
env.put(Context.SECURITY_PRINCIPAL, "joeuser");
env.put(Context.SECURITY_CREDENTIALS, "joepassword");

Context ctx = new InitialContext(env);

But if you are running your code in a Java EE container, these values will be fetched by the container and used to create an InitialContext as below

System.getProperty(Context.PROVIDER_URL);

and

these values will be set while starting the container as JVM arguments. So if you are running the code in a container, the following will work

InitialContext ctx = new InitialContext();

We can separate out section of which we need to convert in PDF

For example, if table is in class "pdf-table-wrap"

After this, we need to call html2canvas function combined with jsPDF

following is sample code

var pdf = new jsPDF('p', 'pt', [580, 630]);
html2canvas($(".pdf-table-wrap")[0], {
    onrendered: function(canvas) {
        document.body.appendChild(canvas);
        var ctx = canvas.getContext('2d');
        var imgData = canvas.toDataURL("image/png", 1.0);
        var width = canvas.width;
        var height = canvas.clientHeight;
        pdf.addImage(imgData, 'PNG', 20, 20, (width - 10), (height));

    }
});
setTimeout(function() {
    //jsPDF code to save file
    pdf.save('sample.pdf');
}, 0);

The easiest way would probably be to put your web resources into the assets folder then call:

webView.loadUrl("file:///android_asset/filename.html");

For Complete Communication between Java and Webview See This

Update: The assets folder is usually the following folder: <project>/src/main/assets This can be changed in the asset folder configuration setting in your <app>.iml file as:

<option name=”ASSETS_FOLDER_RELATIVE_PATH” value=”/src/main/assets” /> See Article Where to place the assets folder in Android Studio

You can use the asXML method as:

<?php

// string to SimpleXMLElement
$xml = new SimpleXMLElement($string);

// make any changes.
....

// convert the SimpleXMLElement back to string.
$newString = $xml->asXML();
?>

You cannot alter a column to be an IDENTITY column. What you'll need to do is create a new column which is defined as an IDENTITY from the get-go, then drop the old column, and rename the new one to the old name.

ALTER TABLE (yourTable) ADD NewColumn INT IDENTITY(1,1)

ALTER TABLE (yourTable) DROP COLUMN OldColumnName

EXEC sp_rename 'yourTable.NewColumn', 'OldColumnName', 'COLUMN'

In Java 8:

Map<String, List<String>> test1 = new LinkedHashMap<String, List<String>>();
test1.forEach((key,value) -> {
    System.out.println(key + " -> " + value);
});

You can use moment js for this purpose. momentJs 'fromNow()' will give you any time difference from current time.

var m1 = any date time on moment format;

console.log(m1.fromNow());

Below gives me opposite of what you have. (Notice Group column)

SELECT
    *
FROM
    myTable
GROUP BY
    Group_value,
    ID
ORDER BY
    count(Group_value)

Let me know if this is fine with you...

I am trying to get what you want too...

I don't recommend you to use Object.keys since its not supported in old IE versions. But if you really need that, you could use the code above to guarantee the back compatibility:

if (!Object.keys) {
Object.keys = (function () {
var hasOwnProperty = Object.prototype.hasOwnProperty,
    hasDontEnumBug = !({toString: null}).propertyIsEnumerable('toString'),
    dontEnums = [
      'toString',
      'toLocaleString',
      'valueOf',
      'hasOwnProperty',
      'isPrototypeOf',
      'propertyIsEnumerable',
      'constructor'
    ],
    dontEnumsLength = dontEnums.length;

return function (obj) {
  if (typeof obj !== 'object' && typeof obj !== 'function' || obj === null) throw new TypeError('Object.keys called on non-object');

  var result = [];

  for (var prop in obj) {
    if (hasOwnProperty.call(obj, prop)) result.push(prop);
  }

  if (hasDontEnumBug) {
    for (var i=0; i < dontEnumsLength; i++) {
      if (hasOwnProperty.call(obj, dontEnums[i])) result.push(dontEnums[i]);
    }
  }
  return result;
}})()};

More info: https://developer.mozilla.org/en-US/docs/JavaScript/Reference/Global_Objects/Object/keys

But if you only need the first one, we could arrange a shorter solution like:

var data = {"key1":"123","key2":"456"};
var first = {};
for(key in data){
    if(data.hasOwnProperty(key)){
        first.key = key;
        first.content =  data[key];
        break;
    }
}
console.log(first); // {key:"key",content:"123"}

• %lu for unsigned long
• %llu for unsigned long long

var time = moment().toDate();  // This will return a copy of the Date that the moment uses

time.setHours(0);
time.setMinutes(0);
time.setSeconds(0);
time.setMilliseconds(0);

If you want, you can deactivate this feature in your git core config using

git config core.autocrlf false

But it would be better to just get rid of the warnings using

git config core.autocrlf true

Another way to find out if a program is installed is by using the which command. It will show the path of the program you're searching for. For example if when your searching for apache you can use the following command:

$ which apache2ctl
/usr/sbin/apache2ctl

And if you searching for PHP try this:

$ which php
/usr/bin/php

If the which command doesn't give any result it means the software is not installed (or is not in the current $PATH):

$ which php
$

In my case, I used the ssl module to "workaround" the certification like so:

import ssl

ssl._create_default_https_context = ssl._create_unverified_context

Then to read your link content, you can use:

urllib.request.urlopen(urllink)

Create a new sub with the following code and assign it to your button. Change the "DeleteProcess" to the name of your code to do the deletion. This will pop up a box with OK or Cancel and will call your delete sub if you hit ok and not if you hit cancel.

Sub AreYouSure()

Dim Sure As Integer

Sure = MsgBox("Are you sure?", vbOKCancel)
If Sure = 1 Then Call DeleteProcess

End Sub

Jesse

Make sure that you have php-xml module installed and enabled in php.ini.

You can also change response format to json which is easier to handle. In that case you have to only add &format=json to url query string.

$rest_url = "http://api.facebook.com/restserver.php?method=links.getStats&format=json&urls=".urlencode($source_url);

And then use json_decode() to retrieve data in your script:

$result = json_decode($content, true);
$fb_like_count = $result['like_count'];

Sorry I know this is an old one but still felt like helping out ^_^

Maybe it's the way I read this but assuming the excel sheet 1 is called "London" and has this information; B5="Marleybone" B6="Paddington" B7="Victoria" B8="Hammersmith". And the excel sheet 2 is called "Nottingham" and has this information; C5="Alverton" C6="Annesley" C7="Arnold" C8="Askham". Then I think this code below would work. ^_^

$xlCellTypeLastCell = 11 
$startRow = 5

$excel = new-object -com excel.application
$wb = $excel.workbooks.open("C:\users\administrator\my_test.xls")

for ($i = 1; $i -le $wb.sheets.count; $i++)
    {
        $sh = $wb.Sheets.Item($i)
        $endRow = $sh.UsedRange.SpecialCells($xlCellTypeLastCell).Row
        $col = $col + $i - 1
        $city = $wb.Sheets.Item($i).name
        $rangeAddress = $sh.Cells.Item($startRow, $col).Address() + ":" + $sh.Cells.Item($endRow, $col).Address()
        $sh.Range($rangeAddress).Value2 | foreach{
            New-Object PSObject -Property @{City = $city; Area=$_}
        }
    }

$excel.Workbooks.Close()

This should be the output (without the commas):

City, Area
---- ----
London, Marleybone
London, Paddington
London, Victoria
London, Hammersmith
Nottingham, Alverton
Nottingham, Annesley
Nottingham, Arnold
Nottingham, Askham

def recall(x): 
    num1 = x[-4:]
    num2 = x[::-1]
    num3 = num2[-4:]
    num4 = [num3, num1]
    return num4

Now just make an variable outside the function and recall the function : like this:

avg = recall("idreesjaneqand") 
print(avg)

The "echo" command in PHP sends the output to the browser as raw html so even if in double quotes the browser will not parse it into two lines because a newline character in HTML means nothing. That's why you need to either use:

echo [output text]."<br>";

when using "echo", or instead use fwrite...

fwrite([output text]."\n");

This will output HTML newline in place of "\n".

Using jQuery it is very simple assuming the URL you wish to post to is on the same server or has implemented CORS

$(function() {
  $("#employeeLink").on("click",function(e) {
    e.preventDefault(); // cancel the link itself
    $.post(this.href,function(data) {
      $("#someContainer").html(data);
    });
  });
});

If you insist on using frames which I strongly discourage, have a form and submit it with the link

<form action="employee.action" method="post" target="myFrame" id="myForm"></form>

and use (in plain JS)

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the link
     document.getElementById("myForm").submit(); // but make sure nothing has name or ID="submit"
   });
 });

Without a form we need to make one

 window.addEventListener("load",function() {
   document.getElementById("employeeLink").addEventListener("click",function(e) {
     e.preventDefault(); // cancel the actual link
     var myForm = document.createElement("form");
     myForm.action=this.href;// the href of the link
     myForm.target="myFrame";
     myForm.method="POST";
     myForm.submit();
   });
 });

Assuming 96dpi is a huge mistake. Even if the assumption is right, there's also an option to scale fonts. So a font set for 10pts may actually be shown as if it's 12.5pt (125%).

You need to write this in the command prompt:

set HTTP_PROXY=http://your_proxy:your_port

Your client application and server application must be under same domain, for example :

client - localhost

server - localhost

and not :

client - localhost:21234

server - localhost

If checkout master was the last thing you did, then the reflog entry HEAD@{1} will contain your commits (otherwise use git reflog or git log -p to find them). Use git merge HEAD@{1} to fast forward them into master.

EDIT:

As noted in the comments, Git Ready has a great article on this.

git reflog and git reflog --all will give you the commit hashes of the mis-placed commits.

Source: http://gitready.com/intermediate/2009/02/09/reflog-your-safety-net.html

Alternatively, in python 3.6+, you can generate Unicode superscript and copy paste that in your code:

ax1.set_ylabel('Rate (min?¹)')

It is naming convention used when passing callbacks in situations that require serial execution of actions, e.g. scan directory -> read file data -> do something with data. This is in preference to deeply nesting the callbacks. The first three sections of the following article on Tim Caswell's HowToNode blog give a good overview of this:

http://howtonode.org/control-flow

Also see the Sequential Actions section of the second part of that posting:

http://howtonode.org/control-flow-part-ii

The control searches for a view in the following order:

• First in shared folder
• Then in the folder matching the current controller (in your case it's Views/DEF)

As you do not have xxx.cshtml in those locations, it returns a "view not found" error.

Solution: You can use the complete path of your view:

Like

 PartialView("~/views/ABC/XXX.cshtml", zyxmodel);

Here is simple example. A contact has one to many associated phone numbers. When a contact is deleted, I want all its associated phone numbers to also be deleted, so I use ON DELETE CASCADE. The one-to-many/many-to-one relationship is implemented with by the foreign key in the phone_numbers.

CREATE TABLE contacts
 (contact_id BIGINT AUTO_INCREMENT NOT NULL,
 name VARCHAR(75) NOT NULL,
 PRIMARY KEY(contact_id)) ENGINE = InnoDB;

CREATE TABLE phone_numbers
 (phone_id BIGINT AUTO_INCREMENT NOT NULL,
  phone_number CHAR(10) NOT NULL,
 contact_id BIGINT NOT NULL,
 PRIMARY KEY(phone_id),
 UNIQUE(phone_number)) ENGINE = InnoDB;

ALTER TABLE phone_numbers ADD FOREIGN KEY (contact_id) REFERENCES \
contacts(contact_id) ) ON DELETE CASCADE;

By adding "ON DELETE CASCADE" to the foreign key constraint, phone_numbers will automatically be deleted when their associated contact is deleted.

INSERT INTO table contacts(name) VALUES('Robert Smith');
INSERT INTO table phone_numbers(phone_number, contact_id) VALUES('8963333333', 1);
INSERT INTO table phone_numbers(phone_number, contact_id) VALUES('8964444444', 1);

Now when a row in the contacts table is deleted, all its associated phone_numbers rows will automatically be deleted.

DELETE TABLE contacts as c WHERE c.id=1; /* delete cascades to phone_numbers */

To achieve the same thing in Doctrine, to get the same DB-level "ON DELETE CASCADE" behavoir, you configure the @JoinColumn with the onDelete="CASCADE" option.

    $em->flush();
} catch(Exception $e) {

    $m = $e->getMessage();
    echo $m . "<br />\n";
}

If you now do

# doctrine orm:schema-tool:create --dump-sql

you will see that the same SQL will be generated as in the first, raw-SQL example

Python is also great for scientific programs such as statistical models or physics sims. I've done monte-carlo programs and, using the VISUAL module, a 3D simulation of the Apollo mission.

This will remove all leading and trailing whitespace in myString:

myString.strip()

So apparently what happened was when I was duplicating my project the framework folder inside my storage folder was not copied to the new directory, this cause my error.

First, you will have to store the value in a variable like this

$value = explode("/", $string);

Then you can use the end function to get the last index from an array like this

echo end($value);

I hope it will work for you.

If you want the String composed of the last three characters, you can use substring(int):

String new_word = word.substring(word.length() - 3);

If you actually want them as a character array, you should write

char[] buffer = new char[3];
int length = word.length();
word.getChars(length - 3, length, buffer, 0);

The first two arguments to getChars denote the portion of the string you want to extract. The third argument is the array into which that portion will be put. And the last argument gives the position in the buffer where the operation starts.

If the string has less than three characters, you'll get an exception in either of the above cases, so you might want to check for that.

I was trying to compare A-B columns and highlight equal text, but usinng the obove fomrulas some text did not match at all. So I used form (VBA macro to compare two columns and color highlight cell differences) codes and I modified few things to adapt it to my application and find any desired column (just by clicking it). In my case, I use large and different numbers of rows on each column. Hope this helps:

vMatch = 1

It is whatever member of the enumeration represents the value 0. Specifically, from the documentation:

The default value of an enum E is the value produced by the expression (E)0.

As an example, take the following enum:

enum E
{
    Foo, Bar, Baz, Quux
}

Without overriding the default values, printing default(E) returns Foo since it's the first-occurring element.

However, it is not always the case that 0 of an enum is represented by the first member. For example, if you do this:

enum F
{
    // Give each element a custom value
    Foo = 1, Bar = 2, Baz = 3, Quux = 0
}

Printing default(F) will give you Quux, not Foo.

If none of the elements in an enum G correspond to 0:

enum G
{
    Foo = 1, Bar = 2, Baz = 3, Quux = 4
}

default(G) returns literally 0, although its type remains as G (as quoted by the docs above, a cast to the given enum type).

I know this is an older question but I'm still using Python 2.4.3 and I needed to find a better way of converting the string of data to a datetime.

The solution if datetime doesn't support %f and without needing a try/except is:

    (dt, mSecs) = row[5].strip().split(".") 
    dt = datetime.datetime(*time.strptime(dt, "%Y-%m-%d %H:%M:%S")[0:6])
    mSeconds = datetime.timedelta(microseconds = int(mSecs))
    fullDateTime = dt + mSeconds 

This works for the input string "2010-10-06 09:42:52.266000"

Yes! there is a way to use a variable as a pointer in python!

I am sorry to say that many of answers were partially wrong. In principle every equal(=) assignation shares the memory address (check the id(obj) function), but in practice it is not such. There are variables whose equal("=") behaviour works in last term as a copy of memory space, mostly in simple objects (e.g. "int" object), and others in which not (e.g. "list","dict" objects).

Here is an example of pointer assignation

dict1 = {'first':'hello', 'second':'world'}
dict2 = dict1 # pointer assignation mechanism
dict2['first'] = 'bye'
dict1
>>> {'first':'bye', 'second':'world'}

Here is an example of copy assignation

a = 1
b = a # copy of memory mechanism. up to here id(a) == id(b)
b = 2 # new address generation. therefore without pointer behaviour
a
>>> 1

Pointer assignation is a pretty useful tool for aliasing without the waste of extra memory, in certain situations for performing comfy code,

class cls_X():
   ...
   def method_1():
      pd1 = self.obj_clsY.dict_vars_for_clsX['meth1'] # pointer dict 1: aliasing
      pd1['var4'] = self.method2(pd1['var1'], pd1['var2'], pd1['var3'])
   #enddef method_1
   ...
#endclass cls_X

but one have to be aware of this use in order to prevent code mistakes.

To conclude, by default some variables are barenames (simple objects like int, float, str,...), and some are pointers when assigned between them (e.g. dict1 = dict2). How to recognize them? just try this experiment with them. In IDEs with variable explorer panel usually appears to be the memory address ("@axbbbbbb...") in the definition of pointer-mechanism objects.

I suggest investigate in the topic. There are many people who know much more about this topic for sure. (see "ctypes" module). I hope it is helpful. Enjoy the good use of the objects! Regards, José Crespo

Prevent saving changes that require table re-creation

Five swift clicks

1. Tools
2. Options
3. Designers
4. Prevent saving changes that require table re-creation
5. OK.

After saving, repeat the proceudure to re-tick the box. This safe-guards against accidental data loss.

Further explanation

• By default SQL Server Management Studio prevents the dropping of tables, because when a table is dropped its data contents are lost.*

• When altering a column's datatype in the table Design view, when saving the changes the database drops the table internally and then re-creates a new one.

*Your specific circumstances will not pose a consequence since your table is empty. I provide this explanation entirely to improve your understanding of the procedure.

Try typing which tensorboard in your terminal. It should exist if you installed with pip as mentioned in the tensorboard README (although the documentation doesn't tell you that you can now launch tensorboard without doing anything else).

You need to give it a log directory. If you are in the directory where you saved your graph, you can launch it from your terminal with something like:

tensorboard --logdir .

or more generally:

tensorboard --logdir /path/to/log/directory

for any log directory.

Then open your favorite web browser and type in localhost:6006 to connect.

That should get you started. As for logging anything useful in your training process, you need to use the TensorFlow Summary API. You can also use the TensorBoard callback in Keras.

It's called a for-each or enhanced for statement. See the JLS §14.14.2.

It's syntactic sugar provided by the compiler for iterating over Iterables and arrays. The following are equivalent ways to iterate over a list:

List<Foo> foos = ...;
for (Foo foo : foos)
{
    foo.bar();
}

// equivalent to:
List<Foo> foos = ...;
for (Iterator<Foo> iter = foos.iterator(); iter.hasNext();)
{
    Foo foo = iter.next();
    foo.bar();
}

and these are two equivalent ways to iterate over an array:

int[] nums = ...;
for (int num : nums)
{
    System.out.println(num);
}

// equivalent to:
int[] nums = ...;
for (int i=0; i<nums.length; i++)
{
    int num = nums[i];
    System.out.println(num);
}

Doing a complete uninstall, including removing paths, etc and reinstalling has solved the problem, very strange problem though.

How to completely remove node.js from Windows

Here is what I had and what caused my "incomplete type error":

#include "X.h" // another already declared class
class Big {...} // full declaration of class A

class Small : Big {
    Small() {}
    Small(X); // line 6
}
//.... all other stuff

What I did in the file "Big.cpp", where I declared the A2's constructor with X as a parameter is..

Big.cpp

Small::Big(X my_x) { // line 9 <--- LOOK at this !
}

I wrote "Small::Big" instead of "Small::Small", what a dumb mistake.. I received the error "incomplete type is now allowed" for the class X all the time (in lines 6 and 9), which made a total confusion..

Anyways, that is where a mistake can happen, and the main reason is that I was tired when I wrote it and I needed 2 hours of exploring and rewriting the code to reveal it.

It doesn't work because it doesn't make sense (so little sense that HTML 5 explicitly forbids it).

To fix it, decide if you want a link or a submit button and use whichever one you actually want (Hint: You don't have a form, so a submit button is nonsense).

My answer is "neither one".

I believe the most "Pythonic" way to do things is to NOT check beforehand if the key is in a dictionary and instead just write code that assumes it's there and catch any KeyErrors that get raised because it wasn't.

This is usually done with enclosing the code in a try...except clause and is a well-known idiom usually expressed as "It's easier to ask forgiveness than permission" or with the acronym EAFP, which basically means it is better to try something and catch the errors instead for making sure everything's OK before doing anything. Why validate what doesn't need to be validated when you can handle exceptions gracefully instead of trying to avoid them? Because it's often more readable and the code tends to be faster if the probability is low that the key won't be there (or whatever preconditions there may be).

Of course, this isn't appropriate in all situations and not everyone agrees with the philosophy, so you'll need to decide for yourself on a case-by-case basis. Not surprisingly the opposite of this is called LBYL for "Look Before You Leap".

As a trivial example consider:

if 'name' in dct:
    value = dct['name'] * 3
else:
    logerror('"%s" not found in dictionary, using default' % name)
    value = 42

vs

try:
    value = dct['name'] * 3
except KeyError:
    logerror('"%s" not found in dictionary, using default' % name)
    value = 42

Although in the case it's almost exactly the same amount of code, the second doesn't spend time checking first and is probably slightly faster because of it (try...except block isn't totally free though, so it probably doesn't make that much difference here).

Generally speaking, testing in advance can often be much more involved and the savings gain from not doing it can be significant. That said, if 'name' in dict: is better for the reasons stated in the other answers.

If you're interested in the topic, this message titled "EAFP vs LBYL (was Re: A little disappointed so far)" from the Python mailing list archive probably explains the difference between the two approached better than I have here. There's also a good discussion about the two approaches in the book Python in a Nutshell, 2nd Ed by Alex Martelli in chapter 6 on Exceptions titled Error-Checking Strategies. (I see there's now a newer 3rd edition, publish in 2017, which covers both Python 2.7 and 3.x).

Change table's default charset:

ALTER TABLE etape_prospection
  CHARACTER SET utf8,
  COLLATE utf8_general_ci;

To change string column charset exceute this query:

ALTER TABLE etape_prospection
  CHANGE COLUMN etape_prosp_comment etape_prosp_comment TEXT CHARACTER SET utf8 COLLATE utf8_general_ci;

when do you call timerReset()? Perhaps you get that error when trying to call it after setTimeout() has already done its thing?

wrap it in

if (window.myTimeout) { 
  clearTimeout(myTimeout);
  myTimeout = setTimeout("timerDone()", 1000 * 1440);
}

edit: Actually, upon further reflection, since you did mention jQuery (and yet don't have any actual jQuery code here... I wonder if you have this nested within some jQuery (like inside a $(document).ready(.. and this is a matter of variable scope. If so, try this:

window.message="Logged in";
window.myTimeout = setTimeout("timerDone()",1000 * 1440);
function timerDone()
{
    window.message="Logged out";   
}
function timerReset()
{


    clearTimeout(window.myTimeout);
    window.myTimeout = setTimeout("timerDone()", 1000 * 1440);
}

You can use the DATE_ADD() function:

... WHERE DATE(DATE_ADD(eventdate, INTERVAL -1 DAY)) = CURRENT_DATE

It can also be used in the SELECT statement:

SELECT DATE_ADD('2010-05-11', INTERVAL 1 DAY) AS Tomorrow;
+------------+
| Tomorrow   |
+------------+
| 2010-05-12 |
+------------+
1 row in set (0.00 sec)

Two problems- List is empty. You need to add some buttons to the list first. Second problem: You can't add buttons to "this". "This" is not referencing what you think, I think. Change this to reference a Panel for instance.

//Assume you have on your .aspx page:
<asp:Panel ID="Panel_Controls" runat="server"></asp:Panel>


private void button1_Click(object sender, EventArgs e)
    {
        List<Button> buttons = new List<Button>();


        for (int i = 0; i < buttons.Capacity; i++)
        {
            Panel_Controls.Controls.Add(buttons[i]);   
        }
    }

text='Python' searches for elements that have the exact text you provided:

import re
from BeautifulSoup import BeautifulSoup

html = """<p>exact text</p>
   <p>almost exact text</p>"""
soup = BeautifulSoup(html)
print soup(text='exact text')
print soup(text=re.compile('exact text'))

Output

[u'exact text']
[u'exact text', u'almost exact text']

"To see if the string 'Python' is located on the page http://python.org":

import urllib2
html = urllib2.urlopen('http://python.org').read()
print 'Python' in html # -> True

If you need to find a position of substring within a string you could do html.find('Python').

How about:

import copy
d = { ... }
d2 = copy.deepcopy(d)

Python 2 or 3:

Python 3.2 (r32:88445, Feb 20 2011, 21:30:00) [MSC v.1500 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.
>>> import copy
>>> my_dict = {'a': [1, 2, 3], 'b': [4, 5, 6]}
>>> my_copy = copy.deepcopy(my_dict)
>>> my_dict['a'][2] = 7
>>> my_copy['a'][2]
3
>>>

Just use Apache commons upload library. Add URIEncoding="UTF-8" to Tomcat's connector, and use FileItem.getString("UTF-8") instead of FileItem.getString() without charset specified.

Hope this help.

I think it's too late to answer this question but I faced the same problem recently my use case was to call the paginated JSON API and get all the data from each pagination and append it to a single array.

const https = require('https');
const apiUrl = "https://example.com/api/movies/search/?Title=";
let finaldata = [];
let someCallBack = function(data){
  finaldata.push(...data);
  console.log(finaldata);
};
const getData = function (substr, pageNo=1, someCallBack) {

  let actualUrl = apiUrl + `${substr}&page=${pageNo}`;
  let mydata = []
  https.get(actualUrl, (resp) => {
    let data = '';
    resp.on('data', (chunk) => {
        data += chunk;
    });
    resp.on('end', async () => {
        if (JSON.parse(data).total_pages!==null){
          pageNo+=1;
          somCallBack(JSON.parse(data).data);
          await getData(substr, pageNo, someCallBack);
        }
    });
  }).on("error", (err) => {
      console.log("Error: " + err.message);
  });
}

getData("spiderman", pageNo=1, someCallBack);

Like @ackuser mentioned we can use other module but In my use case I had to use the node https. Hoping this will help others.
