int is a primitive type, you can read what does mean a primitive type in java here, and a Map is an interface that has to objects as input:

public interface Map<K extends Object, V extends Object>

object means a class, and it means also that you can create an other class that exends from it, but you can not create a class that exends from int. So you can not use int variable as an object. I have tow solutions for your problem:

Map<String, Integer> map = new HashMap<>();

or

Map<String, int[]> map = new HashMap<>();
int x = 1;

//put x in map
int[] x_ = new int[]{x};
map.put("x", x_);

//get the value of x
int y = map.get("x")[0];

Simple and Easy. Remove all columns after the 22th.

df.drop(columns=df.columns[22:]) # love it

$("div.test:not(:first)").hide();

or:

$("div.test:not(:eq(0))").hide();

or:

$("div.test").not(":eq(0)").hide();

or:

$("div.test:gt(0)").hide();

or: (as per @Jordan Lev's comment):

$("div.test").slice(1).hide();

and so on.

Would you be able to use a USB->RS232 adapter? I have a few, and they just use the FTDI driver. Then, you should be able to rename /dev/ttyUSB0 (or whatever gets created) as /dev/ttyS2 .

A simple solution using node.js:

#!/usr/bin/env node
process.stdout.write(require('path').resolve(process.argv[2]));

If you are in a Linux container, such as on a Chromebook, you will need to manually browse to your localhost's address. I am aware the newer Chrome OS versions no longer have this problem, but on my Chromebook, I still had to manually browse to the localhost's address for your code to work.

To browse to your locahost's address, type this in command line: sudo ifconfig

and note the inet address under eth0.

Otherwise, as others have noted, simply type node.js filename and it will work as long as you point the browser to the proper address.

Hope this helps!

You can do it with anchor tags using css3 :target pseudo-selector, this selector is going to be triggered when the element with the same id as the hash of the current URL get an match. Example

Knowing this, we can combine this technique with the use of proximity selectors like "+" and "~" to select any other element through the target element who id get match with the hash of the current url. An example of this would be something like what you are asking.

In some locales like Hebrew, there are leap months dependant upon the year so to avoid errors in such locales you might consider the following solution:

SELECT DATENAME(month, STR(YEAR(GETDATE()), 4) + REPLACE(STR(@month, 2), ' ', '0') + '01')     

FYI, when you using or importing TensorFlow, a similar error may occur, like (caused by NumPy):

I followed Elmira's and Drew's solution, sudo easy_install numpy, and it worked!

sudo easy_install numpy

After that I could use TensorFlow without error.

I like matching the editor dark scheme to IPython dark scheme. As for IPython, go to

Tools > Preferences > IPython cosole > display tab

and check Dark background.

Restart the kernel. Then look at the colors you get, say, when you import. My spyder2 (python 2.7) uses Anaconda's ipython 5.3.0 and import is pink, the best matching scheme for the editor is Monokai, you choose this in

Tools > Preferences > Syntax coloring

My spyder3, when choosing dark IPython (2.4.1) background prints colors a bit different than Monokai, but if you go to

Tools > Preferences > Syntax coloring  

you go to Monokai tab and tweak the colors a bit. I had to change builtin from lilac to cyan

Another way is with: overflow-y:hidden on the parent with padding.

#wrap {
    overflow-y: hidden;
    padding: 0 10px;
}
#wrap > div {
    width: 100px;
    height: 100px;
    box-shadow: 0 0 20px -5px red;
}

For pre 1.7 i would say an equivalent to Integer.compare(x, y) is:

Integer.valueOf(x).compareTo(y);

Create Dynamic angular variables from results

angular.forEach(results, function (value, key) {          
  if (key != null) {                       
    $parse(key).assign($scope, value);                                
  }          
});

ps. don't forget to pass in the $parse attribute into your controller's function

I always use pseudo elements :before and :after for changing the appearance of checkboxes and radio buttons. it's works like a charm.

CODEPEN

Steps

1. Hide the default checkbox using css rules like visibility:hidden or opacity:0 or position:absolute;left:-9999px etc.
2. Create a fake checkbox using :before element and pass either an empty or a non-breaking space '\00a0';
3. When the checkbox is in :checked state, pass the unicode content: "\2713", which is a checkmark;
4. Add :focus style to make the checkbox accessible.
5. Done

Not sure why, but you can wrap DateTime.ToUniversalTime in a try / catch and achieve the same result in more code.

Good luck.

The only way to get the iOS dictation is to sign up yourself through Nuance: http://dragonmobile.nuancemobiledeveloper.com/ - it's expensive, because it's the best. Presumably, Apple's contract prevents them from exposing an API.

The built in iOS accessibility features allow immobilized users to access dictation (and other keyboard buttons) through tools like VoiceOver and Assistive Touch. It may not be worth reinventing this if your users might be familiar with these tools.

As cardern has said list will do the job.

Here is how you can use a named range.

Select your range and enter a new name:

Select your cell that you want a drop down to be in and goto data tab -> data validation.

Select 'List' from the 'Allow' Drop down menu.

Enter your named range like this:

Now you have a drop down linked to your range. If you insert new rows in your range everything will update automatically.

You should use .NET Core, instead of .NET Framework or Xamarin, in the following 6 typical scenarios according to the documentation here.

1. Cross-Platform needs

Clearly, if your goal is to have an application (web/service) that should be able to run across platforms (Windows, Linux and MacOS), the best choice in the .NET ecosystem is to use .NET Core as its runtime (CoreCLR) and libraries are cross-platform. The other choice is to use the Mono Project.

Both choices are open source, but .NET Core is directly and officially supported by Microsoft and will have a heavy investment moving forward.

When using .NET Core across platforms, the best development experience exists on Windows with the Visual Studio IDE which supports many productivity features including project management, debugging, source control, refactoring, rich editing including Intellisense, testing and much more. But rich development is also supported using Visual Studio Code on Mac, Linux and Windows including intellisense and debugging. Even third party editors like Sublime, Emacs, VI and more work well and can get editor intellisense using the open source Omnisharp project.

2. Microservices

When you are building a microservices oriented system composed of multiple independent, dynamically scalable, stateful or stateless microservices, the great advantage that you have here is that you can use different technologies/frameworks/languages at a microservice level. That allows you to use the best approach and technology per micro areas in your system, so if you want to build very performant and scalable microservices, you should use .NET Core. Eventually, if you need to use any .NET Framework library that is not compatible with .NET Core, there’s no issue, you can build that microservice with the .NET Framework and in the future you might be able to substitute it with the .NET Core.

The infrastructure platform you could use are many. Ideally, for large and complex microservice systems, you should use Azure Service Fabric. But for stateless microservices you can also use other products like Azure App Service or Azure Functions.

Note that as of June 2016, not every technology within Azure supports the .NET Core, but .NET Core support in Azure will be increasing dramatically now that .NET Core is RTM released.

3. Best performant and scalable systems

When your system needs the best possible performance and scalability so you get the best responsiveness no matter how many users you have, then is where .NET Core and ASP.NET Core really shine. The more you can do with the same amount of infrastructure/hardware, the richer the experience you’ll have for your end users – at a lower cost.

The days of Moore’s law performance improvements for single CPUs does not apply anymore; yet you need to do more while your system is growing and need higher scalability and performance for everyday’ s more demanding users which are growing exponentially in numbers. You need to get more efficient, optimize everywhere, and scale better across clusters of machines, VMs and CPU cores, ultimately. It is not just a matter of user’s satisfaction; it can also make a huge difference in cost/TCO. This is why it is important to strive for performance and scalability.

As mentioned, if you can isolate small pieces of your system as microservices or any other loosely-coupled approach, it’ll be better as you’ll be able to not just evolve each small piece/microservice independently and have a better long-term agility and maintenance, but also you’ll be able to use any other technology at a microservice level if what you need to do is not compatible with .NET Core. And eventually you’d be able to refactor it and bring it to .NET Core when possible.

4. Command line style development for Mac, Linux or Windows.

This approach is optional when using .NET Core. You can also use the full Visual Studio IDE, of course. But if you are a developer that wants to develop with lightweight editors and heavy use of command line, .NET Core is designed for CLI. It provides simple command line tools available on all supported platforms, enabling developers to build and test applications with a minimal installation on developer, lab or production machines. Editors like Visual Studio Code use the same command line tools for their development experiences. And IDE’s like Visual Studio use the same CLI tools but hide them behind a rich IDE experience. Developers can now choose the level they want to interact with the tool chain from CLI to editor to IDE.

5. Need side by side of .NET versions per application level.

If you want to be able to install applications with dependencies on different versions of frameworks in .NET, you need to use .NET Core which provides 100% side-by side as explained previously in this document.

6. Windows 10 UWP .NET apps.

In addition, you may also want to read:

1. When should I NOT use .NET Core?
2. When should I still use .NET Framework 4.x, instead of .NET Core?
3. When should I use Xamarin, instead of .NET Core?

1. Drop the primary key first: (The primary key is your responsibility)

   ALTER TABLE Persons DROP PRIMARY KEY ;
   

2. Then make all insertions:

3. Add new primary key just like before dropping:

   ALTER TABLE Persons ADD PRIMARY KEY (P_Id);
   

Complementing the answers this is a guide to find the private key of the certificate and add the permissions.

This is the guide to get FindPrivateKey.exe found in the guide for find the private key of the certificate.

And what about this?

public static IEnumerable<Product> GetAllProducts()
{
    using (AdventureWorksEntities db = new AdventureWorksEntities())
    {
        var products = from product in db.Product
                       select product;

        return products.ToList();
    }
}

I guess this is much cleaner. I do not have VS2008 at hand to check, though. In any case, if Products implements IEnumerable (as it seems to - it is used in a foreach statement), I'd return it directly.

How can I make as "perfect" a subclass of dict as possible?

The end goal is to have a simple dict in which the keys are lowercase.

• If I override __getitem__/__setitem__, then get/set don't work. How do I make them work? Surely I don't need to implement them individually?

• Am I preventing pickling from working, and do I need to implement __setstate__ etc?

• Do I need repr, update and __init__?

• Should I just use mutablemapping (it seems one shouldn't use UserDict or DictMixin)? If so, how? The docs aren't exactly enlightening.

The accepted answer would be my first approach, but since it has some issues, and since no one has addressed the alternative, actually subclassing a dict, I'm going to do that here.

What's wrong with the accepted answer?

This seems like a rather simple request to me:

How can I make as "perfect" a subclass of dict as possible? The end goal is to have a simple dict in which the keys are lowercase.

The accepted answer doesn't actually subclass dict, and a test for this fails:

>>> isinstance(MyTransformedDict([('Test', 'test')]), dict)
False

Ideally, any type-checking code would be testing for the interface we expect, or an abstract base class, but if our data objects are being passed into functions that are testing for dict - and we can't "fix" those functions, this code will fail.

Other quibbles one might make:

• The accepted answer is also missing the classmethod: fromkeys.

• The accepted answer also has a redundant __dict__ - therefore taking up more space in memory:

  >>> s.foo = 'bar'
  >>> s.__dict__
  {'foo': 'bar', 'store': {'test': 'test'}}
  

Actually subclassing dict

We can reuse the dict methods through inheritance. All we need to do is create an interface layer that ensures keys are passed into the dict in lowercase form if they are strings.

If I override __getitem__/__setitem__, then get/set don't work. How do I make them work? Surely I don't need to implement them individually?

Well, implementing them each individually is the downside to this approach and the upside to using MutableMapping (see the accepted answer), but it's really not that much more work.

First, let's factor out the difference between Python 2 and 3, create a singleton (_RaiseKeyError) to make sure we know if we actually get an argument to dict.pop, and create a function to ensure our string keys are lowercase:

from itertools import chain
try:              # Python 2
    str_base = basestring
    items = 'iteritems'
except NameError: # Python 3
    str_base = str, bytes, bytearray
    items = 'items'

_RaiseKeyError = object() # singleton for no-default behavior

def ensure_lower(maybe_str):
    """dict keys can be any hashable object - only call lower if str"""
    return maybe_str.lower() if isinstance(maybe_str, str_base) else maybe_str

Now we implement - I'm using super with the full arguments so that this code works for Python 2 and 3:

class LowerDict(dict):  # dicts take a mapping or iterable as their optional first argument
    __slots__ = () # no __dict__ - that would be redundant
    @staticmethod # because this doesn't make sense as a global function.
    def _process_args(mapping=(), **kwargs):
        if hasattr(mapping, items):
            mapping = getattr(mapping, items)()
        return ((ensure_lower(k), v) for k, v in chain(mapping, getattr(kwargs, items)()))
    def __init__(self, mapping=(), **kwargs):
        super(LowerDict, self).__init__(self._process_args(mapping, **kwargs))
    def __getitem__(self, k):
        return super(LowerDict, self).__getitem__(ensure_lower(k))
    def __setitem__(self, k, v):
        return super(LowerDict, self).__setitem__(ensure_lower(k), v)
    def __delitem__(self, k):
        return super(LowerDict, self).__delitem__(ensure_lower(k))
    def get(self, k, default=None):
        return super(LowerDict, self).get(ensure_lower(k), default)
    def setdefault(self, k, default=None):
        return super(LowerDict, self).setdefault(ensure_lower(k), default)
    def pop(self, k, v=_RaiseKeyError):
        if v is _RaiseKeyError:
            return super(LowerDict, self).pop(ensure_lower(k))
        return super(LowerDict, self).pop(ensure_lower(k), v)
    def update(self, mapping=(), **kwargs):
        super(LowerDict, self).update(self._process_args(mapping, **kwargs))
    def __contains__(self, k):
        return super(LowerDict, self).__contains__(ensure_lower(k))
    def copy(self): # don't delegate w/ super - dict.copy() -> dict :(
        return type(self)(self)
    @classmethod
    def fromkeys(cls, keys, v=None):
        return super(LowerDict, cls).fromkeys((ensure_lower(k) for k in keys), v)
    def __repr__(self):
        return '{0}({1})'.format(type(self).__name__, super(LowerDict, self).__repr__())

We use an almost boiler-plate approach for any method or special method that references a key, but otherwise, by inheritance, we get methods: len, clear, items, keys, popitem, and values for free. While this required some careful thought to get right, it is trivial to see that this works.

(Note that haskey was deprecated in Python 2, removed in Python 3.)

Here's some usage:

>>> ld = LowerDict(dict(foo='bar'))
>>> ld['FOO']
'bar'
>>> ld['foo']
'bar'
>>> ld.pop('FoO')
'bar'
>>> ld.setdefault('Foo')
>>> ld
{'foo': None}
>>> ld.get('Bar')
>>> ld.setdefault('Bar')
>>> ld
{'bar': None, 'foo': None}
>>> ld.popitem()
('bar', None)

Am I preventing pickling from working, and do I need to implement __setstate__ etc?

pickling

And the dict subclass pickles just fine:

>>> import pickle
>>> pickle.dumps(ld)
b'\x80\x03c__main__\nLowerDict\nq\x00)\x81q\x01X\x03\x00\x00\x00fooq\x02Ns.'
>>> pickle.loads(pickle.dumps(ld))
{'foo': None}
>>> type(pickle.loads(pickle.dumps(ld)))
<class '__main__.LowerDict'>

__repr__

Do I need repr, update and __init__?

We defined update and __init__, but you have a beautiful __repr__ by default:

>>> ld # without __repr__ defined for the class, we get this
{'foo': None}

However, it's good to write a __repr__ to improve the debugability of your code. The ideal test is eval(repr(obj)) == obj. If it's easy to do for your code, I strongly recommend it:

>>> ld = LowerDict({})
>>> eval(repr(ld)) == ld
True
>>> ld = LowerDict(dict(a=1, b=2, c=3))
>>> eval(repr(ld)) == ld
True

You see, it's exactly what we need to recreate an equivalent object - this is something that might show up in our logs or in backtraces:

>>> ld
LowerDict({'a': 1, 'c': 3, 'b': 2})

Conclusion

Should I just use mutablemapping (it seems one shouldn't use UserDict or DictMixin)? If so, how? The docs aren't exactly enlightening.

Yeah, these are a few more lines of code, but they're intended to be comprehensive. My first inclination would be to use the accepted answer, and if there were issues with it, I'd then look at my answer - as it's a little more complicated, and there's no ABC to help me get my interface right.

Premature optimization is going for greater complexity in search of performance. MutableMapping is simpler - so it gets an immediate edge, all else being equal. Nevertheless, to lay out all the differences, let's compare and contrast.

I should add that there was a push to put a similar dictionary into the collections module, but it was rejected. You should probably just do this instead:

my_dict[transform(key)]

It should be far more easily debugable.

Compare and contrast

There are 6 interface functions implemented with the MutableMapping (which is missing fromkeys) and 11 with the dict subclass. I don't need to implement __iter__ or __len__, but instead I have to implement get, setdefault, pop, update, copy, __contains__, and fromkeys - but these are fairly trivial, since I can use inheritance for most of those implementations.

The MutableMapping implements some things in Python that dict implements in C - so I would expect a dict subclass to be more performant in some cases.

We get a free __eq__ in both approaches - both of which assume equality only if another dict is all lowercase - but again, I think the dict subclass will compare more quickly.

Summary:

• subclassing MutableMapping is simpler with fewer opportunities for bugs, but slower, takes more memory (see redundant dict), and fails isinstance(x, dict)
• subclassing dict is faster, uses less memory, and passes isinstance(x, dict), but it has greater complexity to implement.

Which is more perfect? That depends on your definition of perfect.

You have to escape the & character. Turn your

&

into

&

and you should be good.

If you really need to do it in separate transaction you need to use REQUIRES_NEW and live with the performance overhead. Watch out for dead locks.

I'd rather do it the other way:

• Validate data on Java side.
• Run everyting in one transaction.
• If anything goes wrong on DB side -> it's a major error of DB or validation design. Rollback everything and throw critical top level error.
• Write good unit tests.

You can get the content of a MultipartFile by using the getBytes method and you can write to the file using Files.newOutputStream():

public void write(MultipartFile file, Path dir) {
    Path filepath = Paths.get(dir.toString(), file.getOriginalFilename());

    try (OutputStream os = Files.newOutputStream(filepath)) {
        os.write(file.getBytes());
    }
}

You can also use the transferTo method:

public void multipartFileToFile(
    MultipartFile multipart, 
    Path dir
) throws IOException {
    Path filepath = Paths.get(dir.toString(), multipart.getOriginalFilename());
    multipart.transferTo(filepath);
}

DECLARE @tmp_key int
DECLARE @get_invckey cursor 

SET @get_invckey = CURSOR FOR 
    SELECT invckey FROM tarinvoice WHERE confirmtocntctkey IS NULL AND tranno LIKE '%115876'

OPEN @get_invckey 

FETCH NEXT FROM @get_invckey INTO @tmp_key

DECLARE @PrimaryContactKey int --or whatever datatype it is

WHILE (@@FETCH_STATUS = 0) 
BEGIN 
    SELECT @PrimaryContactKey=c.PrimaryCntctKey
    FROM tarcustomer c, tarinvoice i
    WHERE i.custkey = c.custkey AND i.invckey = @tmp_key

    UPDATE tarinvoice SET confirmtocntctkey = @PrimaryContactKey WHERE invckey = @tmp_key
    FETCH NEXT FROM @get_invckey INTO @tmp_key
END 

CLOSE @get_invckey
DEALLOCATE @get_invckey

EDIT:
This question has gotten a lot more traction than I would have anticipated. Do note that I'm not advocating the use of the cursor in my answer, but rather showing how to assign the value based on the question.

Call parent.remove(panel), where parent is the container that you want the frame in and panel is the panel you want to add.

in postgres, assuming your field type is a timestamp:

select * from table where date_field > (now() - interval '24 hour');

For the asynchronous dispatch case you describe above, you shouldn't need to check if you're on the main thread. As Bavarious indicates, this will simply be queued up to be run on the main thread.

However, if you attempt to do the above using a dispatch_sync() and your callback is on the main thread, your application will deadlock at that point. I describe this in my answer here, because this behavior surprised me when moving some code from -performSelectorOnMainThread:. As I mention there, I created a helper function:

void runOnMainQueueWithoutDeadlocking(void (^block)(void))
{
    if ([NSThread isMainThread])
    {
        block();
    }
    else
    {
        dispatch_sync(dispatch_get_main_queue(), block);
    }
}

which will run a block synchronously on the main thread if the method you're in isn't currently on the main thread, and just executes the block inline if it is. You can employ syntax like the following to use this:

runOnMainQueueWithoutDeadlocking(^{
    //Do stuff
});

From the command line, enter the folder where your database file is located and execute the following command:

chmod 777 databasefilename

This will grant all permissions to all users.

Try this code. I also faced the same problem, but some how I solved it.

If you want to open a windows file explorer, you should call explorer.exe

Call Shell("explorer.exe" & " " & "P:\Engineering", vbNormalFocus)

Equivalent syxntax

Shell "explorer.exe" & " " & "P:\Engineering", vbNormalFocus

Another tool that you may want to use is APK Studio It relies howewer on third party tools: Apktool, jadx, ADB and Uber APK signer that you need to download separately.

A shorter solution (which doesn't force you to repeat the vector name 4 times) would be to use Boost:

#include <boost/range/algorithm_ext/erase.hpp>

// ...

boost::remove_erase(vec, int_to_remove);

See http://www.boost.org/doc/libs/1_64_0/libs/range/doc/html/range/reference/algorithms/new/remove_erase.html

foreach (var item in dicNumber)
{
    listnumber.Add(item.Key);
}

The answer I was searching for was answered here: How to use python argparse with args other than sys.argv?

If main.py and parse_args() is written in this way, then the parsing can be done nicely

# main.py
import argparse
def parse_args():
    parser = argparse.ArgumentParser(description="")
    parser.add_argument('--input', default='my_input.txt')
    return parser

def main(args):
    print(args.input)

if __name__ == "__main__":
    parser = parse_args()
    args = parser.parse_args()
    main(args)

Then you can call main() and parse arguments with parser.parse_args(['--input', 'foobar.txt']) to it in another python script:

# temp.py
from main import main, parse_args
parser = parse_args()
args = parser.parse_args([]) # note the square bracket
# to overwrite default, use parser.parse_args(['--input', 'foobar.txt'])
print(args) # Namespace(input='my_input.txt')
main(args)

Introduction

It represents the scope (the lifetime) of the bean. This is easier to understand if you are familiar with "under the covers" working of a basic servlet web application: How do servlets work? Instantiation, sessions, shared variables and multithreading.

@Request/View/Flow/Session/ApplicationScoped

A @RequestScoped bean lives as long as a single HTTP request-response cycle (note that an Ajax request counts as a single HTTP request too). A @ViewScoped bean lives as long as you're interacting with the same JSF view by postbacks which call action methods returning null/void without any navigation/redirect. A @FlowScoped bean lives as long as you're navigating through the specified collection of views registered in the flow configuration file. A @SessionScoped bean lives as long as the established HTTP session. An @ApplicationScoped bean lives as long as the web application runs. Note that the CDI @Model is basically a stereotype for @Named @RequestScoped, so same rules apply.

Which scope to choose depends solely on the data (the state) the bean holds and represents. Use @RequestScoped for simple and non-ajax forms/presentations. Use @ViewScoped for rich ajax-enabled dynamic views (ajaxbased validation, rendering, dialogs, etc). Use @FlowScoped for the "wizard" ("questionnaire") pattern of collecting input data spread over multiple pages. Use @SessionScoped for client specific data, such as the logged-in user and user preferences (language, etc). Use @ApplicationScoped for application wide data/constants, such as dropdown lists which are the same for everyone, or managed beans without any instance variables and having only methods.

Abusing an @ApplicationScoped bean for session/view/request scoped data would make it to be shared among all users, so anyone else can see each other's data which is just plain wrong. Abusing a @SessionScoped bean for view/request scoped data would make it to be shared among all tabs/windows in a single browser session, so the enduser may experience inconsitenties when interacting with every view after switching between tabs which is bad for user experience. Abusing a @RequestScoped bean for view scoped data would make view scoped data to be reinitialized to default on every single (ajax) postback, causing possibly non-working forms (see also points 4 and 5 here). Abusing a @ViewScoped bean for request, session or application scoped data, and abusing a @SessionScoped bean for application scoped data doesn't affect the client, but it unnecessarily occupies server memory and is plain inefficient.

Note that the scope should rather not be chosen based on performance implications, unless you really have a low memory footprint and want to go completely stateless; you'd need to use exclusively @RequestScoped beans and fiddle with request parameters to maintain the client's state. Also note that when you have a single JSF page with differently scoped data, then it's perfectly valid to put them in separate backing beans in a scope matching the data's scope. The beans can just access each other via @ManagedProperty in case of JSF managed beans or @Inject in case of CDI managed beans.

• Difference between View and Request scope in managed beans
• Advantages of using JSF Faces Flow instead of the normal navigation system
• Communication in JSF2 - Managed bean scopes

@CustomScoped/NoneScoped/Dependent

It's not mentioned in your question, but (legacy) JSF also supports @CustomScoped and @NoneScoped, which are rarely used in real world. The @CustomScoped must refer a custom Map<K, Bean> implementation in some broader scope which has overridden Map#put() and/or Map#get() in order to have more fine grained control over bean creation and/or destroy.

The JSF @NoneScoped and CDI @Dependent basically lives as long as a single EL-evaluation on the bean. Imagine a login form with two input fields referring a bean property and a command button referring a bean action, thus with in total three EL expressions, then effectively three instances will be created. One with the username set, one with the password set and one on which the action is invoked. You normally want to use this scope only on beans which should live as long as the bean where it's being injected. So if a @NoneScoped or @Dependent is injected in a @SessionScoped, then it will live as long as the @SessionScoped bean.

• Expire specific managed bean instance after time interval
• what is none scope bean and when to use it?
• What is the default Managed Bean Scope in a JSF 2 application?

Flash scope

As last, JSF also supports the flash scope. It is backed by a short living cookie which is associated with a data entry in the session scope. Before the redirect, a cookie will be set on the HTTP response with a value which is uniquely associated with the data entry in the session scope. After the redirect, the presence of the flash scope cookie will be checked and the data entry associated with the cookie will be removed from the session scope and be put in the request scope of the redirected request. Finally the cookie will be removed from the HTTP response. This way the redirected request has access to request scoped data which was been prepared in the initial request.

This is actually not available as a managed bean scope, i.e. there's no such thing as @FlashScoped. The flash scope is only available as a map via ExternalContext#getFlash() in managed beans and #{flash} in EL.

• Pass an object between @ViewScoped beans without using GET params

You haven't mentioned the Initial catalog name in the connection string. Give your database name as Initial Catalog name.

<add name ="AutoRepairSqlProvider" connectionString=
     "Data Source=.\SQLEXPRESS; Initial Catalog=MyDatabase; AttachDbFilename=|DataDirectory|\AutoRepairDatabase.mdf;
     Integrated Security=True;User Instance=True"/>

Use os.path.getsize(path) which will

Return the size, in bytes, of path. Raise OSError if the file does not exist or is inaccessible.

import os
os.path.getsize('C:\\Python27\\Lib\\genericpath.py')

Or use os.stat(path).st_size

import os
os.stat('C:\\Python27\\Lib\\genericpath.py').st_size 

Or use Path(path).stat().st_size (Python 3.4+)

from pathlib import Path
Path('C:\\Python27\\Lib\\genericpath.py').stat().st_size

To extend vsync's code further to have the ability to return the timeEnd as a value in NodeJS use this little piece of code.

console.timeEndValue = function(label) { // Add console.timeEndValue, to add a return value
   var time = this._times[label];
   if (!time) {
     throw new Error('No such label: ' + label);
   }
   var duration = Date.now() - time;
   return duration;
};

Now use the code like so:

console.time('someFunction timer');

someFunction();

var executionTime = console.timeEndValue('someFunction timer');
console.log("The execution time is " + executionTime);

This gives you more possibilities. You can store the execution time to be used for more purposes like using it in equations, or stored in a database, sent to a remote client over websockets, served on a webpage, etc.

try it:

const cors = require('cors')

const corsOptions = {
    origin: 'http://localhost:4200',
    credentials: true,

}
app.use(cors(corsOptions));

Everything in the Standard Template/Iostream Library resides in namespace std. You've probably used:

using namespace std;

In your classes, and that's why it worked.

You dont need to define option tags, you can do this using the ngOptions directive: https://docs.angularjs.org/api/ng/directive/ngOptions

<select class="form-control" ng-change="unitChanged()" ng-model="data.unit" ng-options="unit.id as unit.label for unit in units"></select>

What solved the issue on my case was go to:

cd C:\Program Files\Python37\Scripts

And run below command:

easy_install.exe pip

There is a great explanation of defaultdicts here: http://ludovf.net/blog/python-collections-defaultdict/

Basically, the parameters int and list are functions that you pass. Remember that Python accepts function names as arguments. int returns 0 by default and list returns an empty list when called with parentheses.

In normal dictionaries, if in your example I try calling d[a], I will get an error (KeyError), since only keys m, s, i and p exist and key a has not been initialized. But in a defaultdict, it takes a function name as an argument, when you try to use a key that has not been initialized, it simply calls the function you passed in and assigns its return value as the value of the new key.

You can use the forName method of Class:

Class cls = Class.forName(clsName);
Object obj = cls.newInstance();

No, that's not really possible, as

• there can be more than one string giving the same MD5
• it was designed to be hard to "reverse"

The goal of the MD5 and its family of hashing functions is

• to get short "extracts" from long string
• to make it hard to guess where they come from
• to make it hard to find collisions, that is other words having the same hash (which is a very similar exigence as the second one)

Think that you can get the MD5 of any string, even very long. And the MD5 is only 16 bytes long (32 if you write it in hexa to store or distribute it more easily). If you could reverse them, you'd have a magical compacting scheme.

This being said, as there aren't so many short strings (passwords...) used in the world, you can test them from a dictionary (that's called "brute force attack") or even google for your MD5. If the word is common and wasn't salted, you have a reasonable chance to succeed...

An enum's default is whatever enumeration equates to zero. I don't believe this is changeable by attribute or other means.

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

Let's say your primary key is an Integer and the object you save is "ticket", then you can get it like this. When you save the object, a Serializable id is always returned

Integer id = (Integer)session.save(ticket);

You can use ansible-vault for using secret keys in playbooks. Define your password in yml.

ex. pass: secret or

user:
  pass: secret
  name: fake

encrypt your secrets file with :

ansible-vault encrypt /path/to/credential.yml

ansible will ask a password for encrypt it. (i will explain how to use that pass)

And then you can use your variables where you want. No one can read them without vault-key.

Vault key usage:

via passing argument when running playbook.

--ask-vault-pass: secret

or you can save into file like password.txt and hide somewhere. (useful for CI users)

--vault-password-file=/path/to/file.txt

In your case : include vars yml and use your variables.

- include_vars: /path/credential.yml

  - name: Add deployment user
    action: user name={{user.name}} password={{user.pass}}

Updating to use tibble()

You can pass a named vector of length greater than 1 to the by argument of left_join():

library(dplyr)

d1 <- tibble(
  x = letters[1:3],
  y = LETTERS[1:3],
  a = rnorm(3)
  )

d2 <- tibble(
  x2 = letters[3:1],
  y2 = LETTERS[3:1],
  b = rnorm(3)
  )

left_join(d1, d2, by = c("x" = "x2", "y" = "y2"))

Accepted answer was not enough for me. I had to use :

FragmentManager fm = getSupportFragmentManager();
int count = fm.getBackStackEntryCount();
for(int i = 0; i < count; ++i) {
    fm.popBackStackImmediate();
}

Apparently you don't need to specify height at all! Which is great if it changes for some reason (you resize components or change font sizes).

I just followed this tutorial and everything worked: http://natashatherobot.com/ios-autolayout-scrollview/

(Side note: There is no need to implement viewDidLayoutSubviews unless you want to center the view, so the list of steps is even shorter).

Hope that helps!

Swift 2.0+

AudioToolbox now presents the kSystemSoundID_Vibrate as a SystemSoundID type, so the code is:

import AudioToolbox.AudioServices

AudioServicesPlaySystemSound(kSystemSoundID_Vibrate)
AudioServicesPlayAlertSound(kSystemSoundID_Vibrate)

Instead of having to go thru the extra cast step

(Props to @Dov)

Original Answer (Swift 1.x)

And, here's how you do it on Swift (in case you ran into the same trouble as I did)

Link against AudioToolbox.framework (Go to your project, select your target, build phases, Link Binary with Libraries, add the library there)

Once that is completed:

import AudioToolbox.AudioServices

// Use either of these
AudioServicesPlaySystemSound(SystemSoundID(kSystemSoundID_Vibrate))
AudioServicesPlayAlertSound(SystemSoundID(kSystemSoundID_Vibrate))

The cheesy thing is that SystemSoundID is basically a typealias (fancy swift typedef) for a UInt32, and the kSystemSoundID_Vibrate is a regular Int. The compiler gives you an error for trying to cast from Int to UInt32, but the error reads as "Cannot convert to SystemSoundID", which is confusing. Why didn't apple just make it a Swift enum is beyond me.

@aponomarenko's goes into the details, my answer is just for the Swifters out there.

If you were asking how to get the PID of a known command it would resemble something like this:

If you had issued the command below #The command issued was ***

dd if=/dev/diskx of=/dev/disky

Then you would use:

PIDs=$(ps | grep dd | grep if | cut -b 1-5)

What happens here is it pipes all needed unique characters to a field and that field can be echoed using

echo $PIDs

You can get the same effect as a default value by using a trigger

create table my_text

(
   abc text
);

delimiter //
create trigger mytext_trigger before insert on my_text
for each row
begin
   if (NEW.abc is null ) then
      set NEW.abc = 'default text';
   end if;
end
//
delimiter ;

you have to add parameter also @zip

 SqlConnection conn = new SqlConnection("Data Source=;Initial Catalog=;Persist Security Info=True;User ID=;Password=");
      conn.Open();
      SqlCommand command = new SqlCommand("Select id from [table1] where name=@zip", conn);
      //
    // Add new SqlParameter to the command.
    //
      command.Parameters.AddWithValue("@zip","india");
      int result = (Int32) (command.ExecuteScalar());
      using (SqlDataReader reader = command.ExecuteReader())
      {
          // iterate your results here
       Console.WriteLine(String.Format("{0}",reader["id"]));

      }
      conn.Close();

If you have used them in C, then they are almost same as were in C.

From the manpage of fopen() function : -

• r+ : - Open for reading and writing. The stream is positioned at the beginning of the file.
  
  
• a+ : - Open for reading and writing. The file is created if it does not exist. The stream is positioned at the end of the file. Subse- quent writes to the file will always end up at the then current end of file, irrespective of any intervening fseek(3) or similar.

Use all() method - it's designed to return items of Collection:

/**
 * Get all of the items in the collection.
 *
 * @return array
 */
public function all()
{
    return $this->items;
}

I had the same problem i think and found a solution in this:

-webkit-column-fill: auto; /* Chrome, Safari, Opera */
-moz-column-fill: auto; /* Firefox */
column-fill: auto;  

Working also in FF 38.0.5: http://jsfiddle.net/rkzj8qnv/

You can use default javascript cookies set method. this working perfect.

createCookieInHour: (cookieName, cookieValue, hourToExpire) => {
    let date = new Date();
    date.setTime(date.getTime()+(hourToExpire*60*60*1000));
    document.cookie = cookieName + " = " + cookieValue + "; expires = " +date.toGMTString();
},

call java scripts funtion in react method as below,

createCookieInHour('cookieName', 'cookieValue', 5);

and you can use below way to view cookies.

let cookie = document.cookie.split(';');
console.log('cookie : ', cookie);

please refer below document for more information - URL

I spent multiple days on this issue. I finally got it resolved with the following combination of suggestions from this post.

1. Change platform target to Any CPU. I did not have this configuration currently, so I had to go to the Configuration Manager and add it. I was specifically compiling for x64. This alone did not resolve the error.
2. Change the output path to bin\ instead of bin\x64\Debug. I had tried this several times already before I changed the platform target. It never made a difference other than getting an error that it failed to load the assembly because of an invalid format.

To be clear, I had to do both of these before it started working. I had tried them individually multiple times but it never fixed it until I did both.

If I change either one of these settings back to the original, I get the same error again, despite having run Clean Solution, and manually deleting everything in the bin directory.

Remember that in onClick={ ... }, the ... is a JavaScript expression. So

... onClick={this.handleRemove(id)}

is the same as

var val = this.handleRemove(id);
... onClick={val}

In other words, you call this.handleRemove(id) immediately, and pass that value to onClick, which isn't what you want.

Instead, you want to create a new function with one of the arguments already prefilled; essentially, you want the following:

var newFn = function() {
  var args = Array.prototype.slice.call(arguments);

  // args[0] contains the event object
  this.handleRemove.apply(this, [id].concat(args));
}
... onClick={newFn}

There is a way to express this in ES5 JavaScript: Function.prototype.bind.

... onClick={this.handleRemove.bind(this, id)}

If you use React.createClass, React automatically binds this for you on instance methods, and it may complain unless you change it to this.handleRemove.bind(null, id).

You can also simply define the function inline; this is made shorter with arrow functions if your environment or transpiler supports them:

... onClick={() => this.handleRemove(id)}

If you need access to the event, you can just pass it along:

... onClick={(evt) => this.handleRemove(id, evt)}

Basically in this case, System.Data.OracleClient need access to some of the oracle dll which are not part of .Net. Solutions:

• Install Oracle Client , and add bin location to Path environment varaible of windows OR
• Copy oraociicus10.dll (Basic-Lite version) or aociei10.dll (Basic version), oci.dll, orannzsbb10.dll and oraocci10.dll from oracle client installable folder to bin folder of application so that application is able to find required dll

You want $_SERVER['REQUEST_URI']. From the docs:

'REQUEST_URI'

The URI which was given in order to access this page; for instance, '/index.html'.

Try the points mentioned by @Robert Karl in this thread . If nothing works then you can surely see the logs through android device monitor.

1. Launch the android device monitor

2. select DDMS perspective ,

3. then select your device as shown in the screenshot .

   You can apply filter as per your requirements

I think the best that's possible in cross-browser JavaScript is window.print(), which (in Firefox 3, for me) brings up the 'print' dialog and not the print preview dialog.

FYI, the print dialog is your computer's Print popup, what you get when you do Ctrl-p. The print preview is Firefox's own Preview window, and it has more options. It's what you get with Firefox Menu > Print...

Once you've done this

group p by p.SomeId into pg  

you no longer have access to the range variables used in the initial from. That is, you can no longer talk about p or bp, you can only talk about pg.

Now, pg is a group and so contains more than one product. All the products in a given pg group have the same SomeId (since that's what you grouped by), but I don't know if that means they all have the same BaseProductId.

To get a base product name, you have to pick a particular product in the pg group (As you are doing with SomeId and CountryCode), and then join to BaseProducts.

var result = from p in Products                         
 group p by p.SomeId into pg                         
 // join *after* group
 join bp in BaseProducts on pg.FirstOrDefault().BaseProductId equals bp.Id         
 select new ProductPriceMinMax { 
       SomeId = pg.FirstOrDefault().SomeId, 
       CountryCode = pg.FirstOrDefault().CountryCode, 
       MinPrice = pg.Min(m => m.Price), 
       MaxPrice = pg.Max(m => m.Price),
       BaseProductName = bp.Name  // now there is a 'bp' in scope
 };

That said, this looks pretty unusual and I think you should step back and consider what you are actually trying to retrieve.

It's torture. Instead of including a generic conf file, they make you hit return 9000 times to generate one.

I was also struggling with this problem, and find that the best way is to use a CURSOR.

I have tried Denis solution with OUTPUT, but as he mentiond, it's impossible to output external columns in an insert statement, and the MERGE can't work when insert multiple rows by select.

So, i've used a CURSOR, for each row in the outer table, i've done a INSERT, then use the @@IDENTITY for another INSERT.

DECLARE @OuterID int

DECLARE MY_CURSOR CURSOR 
  LOCAL STATIC READ_ONLY FORWARD_ONLY
FOR 
SELECT  ID FROM   [external_Table]

OPEN MY_CURSOR
FETCH NEXT FROM MY_CURSOR INTO @OuterID

WHILE @@FETCH_STATUS = 0
BEGIN 
INSERT INTO [Table]   (data)
    SELECT data
    FROM     [external_Table] where ID = @OuterID 

    INSERT INTO [second_table] (FK,OuterID)
    VALUES(@OuterID,@@identity)

    FETCH NEXT FROM MY_CURSOR INTO @OuterID
END
CLOSE MY_CURSOR
DEALLOCATE MY_CURSOR

The database.yml is the file where you set up all the information to connect to the database. It differs depending on the kind of DB you use. You can find more information about this in the Rails Guide or any tutorial explaining how to setup a rails project.

The information in the database.yml file is scoped by environment, allowing you to get a different setting for testing, development or production. It is important that you keep those distinct if you don't want the data you use for development deleted by mistake while running your test suite.

Regarding source control, you should not commit this file but instead create a template file for other developers (called database.yml.template). When deploying, the convention is to create this database.yml file in /shared/config directly on the server.

With SVN: svn propset svn:ignore config "database.yml"

With Git: Add config/database.yml to the .gitignore file or with git-extra git ignore config/database.yml

... and now, some examples:

SQLite

MongoDB with MongoID (called mongoid.yml, but basically the same thing)

Disabling user-scalable (namely, the ability to double tap to zoom) allows the browser to reduce the click delay. In touch-enable browsers, when the user expects the double tap to zoom, the browser generally waits 300ms before firing the click event, waiting to see if the user will double tap. Disabling user-scalable allows for the Chrome browser to fire the click event immediately, allowing for a better user experience.

From Google IO 2013 session https://www.youtube.com/watch?feature=player_embedded&v=DujfpXOKUp8#t=1435s

Update: its not true anymore, <meta name="viewport" content="width=device-width"> is enough to remove 300ms delay

Assuming that create and destroy are free functions (which seems to be the case from the OP's code snippet) with the following signatures:

Bar* create();
void destroy(Bar*);

You can write your class Foo like this

class Foo {

    std::unique_ptr<Bar, void(*)(Bar*)> ptr_;

    // ...

public:

    Foo() : ptr_(create(), destroy) { /* ... */ }

    // ...
};

Notice that you don't need to write any lambda or custom deleter here because destroy is already a deleter.

If you are dealing with LiveData, when updating value instead of using liveData.value = someValue try to do liveData.postValue(someValue)

Below function to save files, just pass your base64 file, it return filename save it in DB.

import fs from 'fs';
 const uuid = require('uuid/v1');

/*Download the base64 image in the server and returns the filename and path of image.*/
function saveImage(baseImage) {
    /*path of the folder where your project is saved. (In my case i got it from config file, root path of project).*/
    const uploadPath = "/home/documents/project";
    //path of folder where you want to save the image.
    const localPath = `${uploadPath}/uploads/images/`;
    //Find extension of file
    const ext = baseImage.substring(baseImage.indexOf("/")+1, baseImage.indexOf(";base64"));
    const fileType = baseImage.substring("data:".length,baseImage.indexOf("/"));
    //Forming regex to extract base64 data of file.
    const regex = new RegExp(`^data:${fileType}\/${ext};base64,`, 'gi');
    //Extract base64 data.
    const base64Data = baseImage.replace(regex, "");
    const filename = `${uuid()}.${ext}`;

    //Check that if directory is present or not.
    if(!fs.existsSync(`${uploadPath}/uploads/`)) {
        fs.mkdirSync(`${uploadPath}/uploads/`);
    }
    if (!fs.existsSync(localPath)) {
        fs.mkdirSync(localPath);
    }
    fs.writeFileSync(localPath+filename, base64Data, 'base64');
    return filename;
}

My answer is similar to the others. If you do not want to create a new function you can use what pandas has defined for you already. Use the pipe method.

df.pipe(lambda d: d[d['column'] == value])

I faced a similar kind of issue while using a custom object as a key in Treemap. Whenever you are using a custom object as a key in hashmap then you override two function equals and hashcode, However if you are using ContainsKey method of Treemap on this object then you need to override CompareTo method as well otherwise you will be getting this error Someone using a custom object as a key in hashmap in kotlin should do like following

 data class CustomObjectKey(var key1:String = "" , var 
 key2:String = ""):Comparable<CustomObjectKey?>
 {
override fun compareTo(other: CustomObjectKey?): Int {
    if(other == null)
        return -1
   // suppose you want to do comparison based on key 1 
    return this.key1.compareTo((other)key1)
}

override fun equals(other: Any?): Boolean {
    if(other == null)
        return false
    return this.key1 == (other as CustomObjectKey).key1
}

override fun hashCode(): Int {
    return this.key1.hashCode()
} 
}

If you are using Java 7+, you may want to use NIO.2, e.g.:

❍ Code:

public static void main(String[] args) throws Exception {

    File file = new File("test.csv");

    List<String> lines = Files.readAllLines(file.toPath(), 
            StandardCharsets.UTF_8);

    for (String line : lines) {
        String[] array = line.split(",", -1);
        System.out.println(array[0]);
    }

}

❍ Output:

a
1RW
1RW
1RW
1RW
1RW
1RW
1R1W
1R1W
1R1W

I see most of the developers use inline query without looking out it's impact on huge data.

in simple you can achieve this by:

select a.chargeId, a.chargeType, a.serviceMonth 
from invoice a
left outer join invoice b
on a.chargeId=b.chargeId and a.serviceMonth <b.serviceMonth 
where b.chargeId is null
order by a.serviceMonth desc

Consider supplementing, not replacing, MSTest with another testing framework. You can keep Visual Studio MSTest integration while getting the benefits of a more full-featured testing framework.

For example, i use xUnit with MSTest. Add a reference to the xUnit.dll assembly, and just do something like this. Suprisingly, it just works!

using Microsoft.VisualStudio.TestTools.UnitTesting;
using Assert = Xunit.Assert;  // <-- Aliasing the Xunit namespace is key

namespace TestSample
{
    [TestClass]
    public class XunitTestIntegrationSample
    {
        [TestMethod]
        public void TrueTest()
        {
            Assert.True(true);  // <-- this is the Xunit.Assert class
        }

        [TestMethod]
        public void FalseTest()
        {
            Assert.False(true);
        }
    }
}

here is simple solution i hope it will help you. here's a simple example to improve answer.

$('[type="radio"]').click(function () {

            if ($(this).attr('checked')) {

                $(this).removeAttr('checked');
                $(this).prop('checked',false);

            } else {

                $(this).attr('checked', 'checked');

            }
        });

Demo sorry for too late.. :)

The new ASP.NET Web API is a continuation of the previous WCF Web API project (although some of the concepts have changed).

WCF was originally created to enable SOAP-based services. For simpler RESTful or RPCish services (think clients like jQuery) ASP.NET Web API should be good choice.

For us, WCF is used for SOAP and Web API for REST. I wish Web API supported SOAP too. We are not using advanced features of WCF. Here is comparison from MSDN:

ASP.net Web API is all about HTTP and REST based GET,POST,PUT,DELETE with well know ASP.net MVC style of programming and JSON returnable; web API is for all the light weight process and pure HTTP based components. For one to go ahead with WCF even for simple or simplest single web service it will bring all the extra baggage. For light weight simple service for ajax or dynamic calls always WebApi just solves the need. This neatly complements or helps in parallel to the ASP.net MVC.

Check out the podcast : Hanselminutes Podcast 264 - This is not your father's WCF - All about the WebAPI with Glenn Block by Scott Hanselman for more information.

In the scenarios listed below you should go for WCF:

1. If you need to send data on protocols like TCP, MSMQ or MIME
2. If the consuming client just knows how to consume SOAP messages

WEB API is a framework for developing RESTful/HTTP services.

There are so many clients that do not understand SOAP like Browsers, HTML5, in those cases WEB APIs are a good choice.

HTTP services header specifies how to secure service, how to cache the information, type of the message body and HTTP body can specify any type of content like HTML not just XML as SOAP services.

I know this is a little late answer,

you can use if and else statements in ejs as follows

<% if (something) { %>
   // Then do some operation
<% } else { %>
   // Then do some operation
<% } %>

But there is another thing I want to emphasize is that if you use the code this way,

<% if (something) { %>
   // Then do some operation
<% } %>
<% else { %>
   // Then do some operation
<% } %>

It will produce an error.

Hope this will help to someone

jQuery 3

As of jQuery 3, removeAttr does not set the corresponding property to false anymore:

Prior to jQuery 3.0, using .removeAttr() on a boolean attribute such as checked, selected, or readonly would also set the corresponding named property to false. This behavior was required for ancient versions of Internet Explorer but is not correct for modern browsers because the attribute represents the initial value and the property represents the current (dynamic) value.

It is almost always a mistake to use .removeAttr( "checked" ) on a DOM element. The only time it might be useful is if the DOM is later going to be serialized back to an HTML string. In all other cases, .prop( "checked", false ) should be used instead.

Changelog

Hence only .prop('checked',false) is correct way when using this version.

Original answer (from 2011):

For attributes which have underlying boolean properties (of which checked is one), removeAttr automatically sets the underlying property to false. (Note that this is among the backwards-compatibility "fixes" added in jQuery 1.6.1).

So, either will work... but the second example you gave (using prop) is the more correct of the two. If your goal is to uncheck the checkbox, you really do want to affect the property, not the attribute, and there's no need to go through removeAttr to do that.

Use a negative lookahead and a negative lookbehind:

> s = "one two 3.4 5,6 seven.eight nine,ten"
> parts = re.split('\s|(?<!\d)[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten']

In other words, you always split by \s (whitespace), and only split by commas and periods if they are not followed (?!\d) or preceded (?<!\d) by a digit.

DEMO.

EDIT: As per @verdesmarald comment, you may want to use the following instead:

> s = "one two 3.4 5,6 seven.eight nine,ten,1.2,a,5"
> print re.split('\s|(?<!\d)[,.]|[,.](?!\d)', s)
['one', 'two', '3.4', '5,6', 'seven', 'eight', 'nine', 'ten', '1.2', 'a', '5']

This will split "1.2,a,5" into ["1.2", "a", "5"].

DEMO.

Worked great on CentOS 6.5

Sweet!

Deny from all 

is an .htaccess command(the actual content of that file you are trying to view). Not a denial of being able to edit the file. Just reopen the .htaccess file in the text viewer of choice and make the alterations as you so desire, save it, then reupload it to your folder of choice.

Though I think inadvertently you are blocking even yourself from viewing said application once uploaded.

I would do something like:

order deny,allow
deny from all
allow from 127.0.0.1

which will deny everyone but the IP in the allow from line, which you would change the IP to match your IP which you can obtain from http://www.whatismyip.com/ or similar site.

You need to use JavaScript in your HTML and make sure you are using forms so that. You may finally serialize the data using Ajax method to push the data from HTML into database

Just super(); alone will call the default constructor, if it exists of a class's superclass. But you must explicitly write the default constructor yourself. If you don't a Java will generate one for you with no implementations, save super(); , referring to the universal Superclass Object, and you can't call it in a subclass.

public class Alien{
   public Alien(){ //Default constructor is written out by user
   /** Implementation not shown…**/
   }
}

public class WeirdAlien extends Alien{
   public WeirdAlien(){
   super(); //calls the default constructor in Alien.
   }

}

You can use the -notmatch operator to get the lines that don't have the characters you are interested in.

     Get-Content $FileName | foreach-object { 
     if ($_ -notmatch $arrayofStringsNotInterestedIn) { $) }

There's no fixed time for retransmission. Simple implementations estimate the RTT (round-trip-time) and if no ACK to send data has been received in 2x that time then they re-send.

They then double the wait-time and re-send once more if again there is no reply. Rinse. Repeat.

More sophisticated systems make better estimates of how long it should take for the ACK as well as guesses about exactly which data has been lost.

The bottom-line is that there is no hard-and-fast rule about exactly when to retransmit. It's up to the implementation. All retransmissions are triggered solely by the sender based on lack of response from the receiver.

TCP never drops data so no, there is no way to indicate a server should forget about some segment.

Old question but throwing my solution into the ring for completeness. I needed this when I needed a specific find but a different create if it doesn't exist.

def self.find_by_or_create_with(args, attributes) # READ CAREFULLY! args for finding, attributes for creating!
        obj = self.find_or_initialize_by(args)
        return obj if obj.persisted?
        return obj if obj.update_attributes(attributes) 
end

You could do something like this:

\documentclass{article}

\begin{document}

Normal:

\begin{itemize}
  \item foo
  \item bar
  \item baz
\end{itemize}

Less space:

\begin{itemize}
  \setlength{\itemsep}{1pt}
  \setlength{\parskip}{0pt}
  \setlength{\parsep}{0pt}
  \item foo
  \item bar
  \item baz
\end{itemize}

\end{document}

One solution is to run manually a shell function that sets my environment to work or personal, but I am pretty sure that I will often forget to switch to the correct identity resulting in committing under the wrong identity.

That was exactly my problem. I have written a hook script which warns you if you have any github remote and not defined a local username.

Here's how you set it up:

1. Create a directory to hold the global hook

   mkdir -p ~/.git-templates/hooks

2. Tell git to copy everything in ~/.git-templates to your per-project .git directory when you run git init or clone

   git config --global init.templatedir '~/.git-templates'

3. And now copy the following lines to ~/.git-templates/hooks/pre-commit and make the file executable (don't forget this otherwise git won't execute it!)

#!/bin/bash

RED='\033[0;31m' # red color
NC='\033[0m' # no color

GITHUB_REMOTE=$(git remote -v | grep github.com)
LOCAL_USERNAME=$(git config --local user.name)

if [ -n "$GITHUB_REMOTE" ] && [ -z "$LOCAL_USERNAME" ]; then
    printf "\n${RED}ATTENTION: At least one Github remote repository is configured, but no local username. "
    printf "Please define a local username that matches your Github account.${NC} [pre-commit hook]\n\n"
    exit 1
fi

If you use other hosts for your private repositories you have to replace github.com according to your needs.

Now every time you do a git init or git clone git will copy this script to the repository and executes it before any commit is done. If you have not set a local username it will output a warning and won't let you commit.

As indicated in the online manual, the most common cause for that error is that lines are indented with spaces when make expects tab characters.

Correct

target: 
\tcmd

where \t is TAB (U+0009)

Wrong

target:
....cmd

where each . represents a SPACE (U+0020).

Make sure it's not redefined again lower down in your settings.py. The default settings has:

ALLOWED_HOSTS = []

You can use case in update and SWAP as many as you want

update Table SET column=(case when is_row_1 then value_2 else value_1 end) where rule_to_match_swap_columns

To convert a TCHAR CString to ASCII, use the CT2A macro - this will also allow you to convert the string to UTF8 (or any other Windows code page):

// Convert using the local code page
CString str(_T("Hello, world!"));
CT2A ascii(str);
TRACE(_T("ASCII: %S\n"), ascii.m_psz);

// Convert to UTF8
CString str(_T("Some Unicode goodness"));
CT2A ascii(str, CP_UTF8);
TRACE(_T("UTF8: %S\n"), ascii.m_psz);

// Convert to Thai code page
CString str(_T("Some Thai text"));
CT2A ascii(str, 874);
TRACE(_T("Thai: %S\n"), ascii.m_psz);

There is also a macro to convert from ASCII -> Unicode (CA2T) and you can use these in ATL/WTL apps as long as you have VS2003 or greater.

See the MSDN for more info.

Try this:

    ServersTable.Columns.Clear();
    ServersTable.DataSource = SBind;

If you don't want to clear all the existing columns, you have to set DataPropertyName for each existing column like this:

for (int i = 0; i < ServersTable.ColumnCount; ++i) {
  DTable.Columns.Add(new DataColumn(ServersTable.Columns[i].Name));
  ServersTable.Columns[i].DataPropertyName = ServersTable.Columns[i].Name;
}

You could also do this to make it more dynamic.

<input name="filterByPolarity" data-ng-model="text.polarity"/>

Then you ng-repeat will look like this

<div class="tweet" data-ng-repeat="tweet in tweets | filter:text"></div>

This filter will of course only be used to filter by polarity

This is what I used to accomplish to this:

System.IO.Path.Combine(System.AppDomain.CurrentDomain.BaseDirectory, System.AppDomain.CurrentDomain.RelativeSearchPath ?? "");

If you are trying to do redirect in beforeAction() you should use send() method

 return $this->redirect('/some/url',302)->send();

Using toJSON() date function as below:

var sqlDatetime = new Date(new Date().getTime() - new Date().getTimezoneOffset() * 60 * 1000).toJSON().slice(0, 19).replace('T', ' ');
console.log(sqlDatetime);

As detailed in the Oracle Java SE Support Roadmap

After April 2015, Oracle will no longer post updates of Java SE 7 to its public download sites. Existing Java SE 7 downloads already posted as of April 2015 will remain accessible in the Java Archive

Check the Java SE 7 Archive Downloads page. The last release was update 80, therefore the 32-bit filename to download is jdk-7u80-windows-i586.exe (64-bit is named jdk-7u80-windows-x64.exe.

Old Java downloads also require a sign on to an Oracle account now :-( however with some crafty cookie creating one can use wget to grab the file without signing in.

wget --no-cookies --no-check-certificate --header "Cookie: gpw_e24=http%3A%2F%2Fwww.oracle.com%2F; oraclelicense=accept-securebackup-cookie" "http://download.oracle.com/otn-pub/java/jdk/7u80-b15/jdk-7u80-windows-i586.exe"

1. use sys.argv to get the command-line parameters
2. use open(), read() to manipulate file
3. use the Python re module to match lines

If no provider is enabled, "passive" is the best provider returned. See https://stackoverflow.com/a/4519414/621690

    public boolean isLocationServiceEnabled() {
        LocationManager lm = (LocationManager)
                this.getSystemService(Context.LOCATION_SERVICE);
        String provider = lm.getBestProvider(new Criteria(), true);
        return (StringUtils.isNotBlank(provider) &&
                !LocationManager.PASSIVE_PROVIDER.equals(provider));
    }

If your div has a fixed-width it shouldn't expand, because you've fixed its width. However, modern browsers support a min-width CSS property.

You can emulate the min-width property in old IE browsers by using CSS expressions or by using auto width and having a spacer object in the container. This solution isn't elegant but may do the trick:

<div id="container" style="float: left">
  <div id="spacer" style="height: 1px; width: 300px"></div>
  <button>Button 1 text</button>
  <button>Button 2 text</button>
</div>

This is what I did:

$ wget http://sourceforge.net/projects/mcrypt/files/Libmcrypt/2.5.8/libmcrypt-2.5.8.tar.gz/download
$ tar xzvf libmcrypt-2.5.8.tar.gz
$ ./configure
$ make
$ sudo make install

$ brew install autoconf

$ wget file:///Users/rmatikolai/Downloads/php-5.4.24.tar.bz2
$ tar xjvf php-5.4.24.tar.bz2
$ cd php-5.4.24/ext/mcrypt
$ phpize
$ ./configure # this is the step which fails without the above dependencies
$ make
$ make test
$ sudo make install


$ sudo cp /private/etc/php.ini.default /private/etc/php.ini
$ sudo vi /private/etc/php.ini

Next, you need to add the line:

extension=mcrypt.so

$ sudo apachectl restart

LCASE or UCASE respectively.

Example:

SELECT UCASE(MyColumn) AS Upper, LCASE(MyColumn) AS Lower

One can use vim for that:

find -type f \( -name '*.css' -o -name '*.html' -o -name '*.js' -o -name '*.php' \) -execdir vim -c retab -c wq {} \;

As Carpetsmoker stated, it will retab according to your vim settings. And modelines in the files, if any. Also, it will replace tabs not only at the beginning of the lines. Which is not what you generally want. E.g., you might have literals, containing tabs.

void Keep()

Calling this method with in the current action ensures that all the items in TempData are not removed at the end of the current request.

    @model MyProject.Models.EmpModel;
    @{
    Layout = "~/Views/Shared/_Layout.cshtml";
    ViewBag.Title = "About";
    var tempDataEmployeet = TempData["emp"] as Employee; //need typcasting
    TempData.Keep(); // retains all strings values
    } 

void Keep(string key)

Calling this method with in the current action ensures that specific item in TempData is not removed at the end of the current request.

    @model MyProject.Models.EmpModel;
    @{
    Layout = "~/Views/Shared/_Layout.cshtml";
    ViewBag.Title = "About";
    var tempDataEmployeet = TempData["emp"] as Employee; //need typcasting
    TempData.Keep("emp"); // retains only "emp" string values
    } 

Use the following code:

function hide {
document.getElementById('div').style.display = "none";
}
function show {
document.getElementById('div').style.display = "block";
}

There are a lot of ways to do so, for example:

in case you have not pushed the commit publicly yet:

git reset HEAD~1 --soft   

That's it, your commit changes will be in your working directory, whereas the LAST commit will be removed from your current branch. See git reset man

In case you did push publicly (on a branch called 'master'):

git checkout -b MyCommit //save your commit in a separate branch just in case (so you don't have to dig it from reflog in case you screw up :) )

revert commit normally and push

git checkout master
git revert a8172f36 #hash of the commit you want to destroy
# this introduces a new commit (say, it's hash is 86b48ba) which removes changes, introduced in the commit in question (but those changes are still visible in the history)
git push origin master

now if you want to have those changes as you local changes in your working copy ("so that your local copy keeps the changes made in that commit") - just revert the revert commit with --no-commit option:

git revert --no-commit 86b48ba (hash of the revert commit).

I've crafted a small example: https://github.com/Isantipov/git-revert/commits/master

Uncheck Always Show Toolbar in Full Screen in View menu:

and go to fullscreen then:

Alt+Cmd+F - on Mac

F11 - on Windows

You need to write() the read() data into the new file:

ssize_t nrd;
int fd;
int fd1;

fd = open(aa[1], O_RDONLY);
fd1 = open(aa[2], O_CREAT | O_WRONLY, S_IRUSR | S_IWUSR);
while (nrd = read(fd,buffer,50)) {
    write(fd1,buffer,nrd);
}

close(fd);
close(fd1);

Update: added the proper opens...

Btw, the O_CREAT can be OR'd (O_CREAT | O_WRONLY). You are actually opening too many file handles. Just do the open once.

Be aware that the function File.GetLastWriteTime does not always work as expected, the values are sometimes not instantaneously updated by the OS. You may get an old Timestamp, even if the file has been modified right before.

The behaviour may vary between OS versions. For example, this unit test worked well every time on my developer machine, but it always fails on our build server.

  [TestMethod]
  public void TestLastModifiedTimeStamps()
  {
     var tempFile = Path.GetTempFileName();
     var lastModified = File.GetLastWriteTime(tempFile);
     using (new FileStream(tempFile, FileMode.Create, FileAccess.Write, FileShare.None))
     {

     }
     Assert.AreNotEqual(lastModified, File.GetLastWriteTime(tempFile));
  }

See File.GetLastWriteTime seems to be returning 'out of date' value

Your options:

a) live with the occasional omissions.

b) Build up an active component realising the observer pattern (eg. a tcp server client structure), communicating the changes directly instead of writing / reading files. Fast and flexible, but another dependency and a possible point of failure (and some work, of course).

c) Ensure the signalling process by replacing the content of a dedicated signal file that other processes regularly read. It´s not that smart as it´s a polling procedure and has a greater overhead than calling File.GetLastWriteTime, but if not checking the content from too many places too often, it will do the work.

        Assert.IsFalse(fileSignal2.CheckIfSignalled());
    }

Had a similar problem, but in Windows. I was trying to figure out how to open a large MySql sql file in Windows, and these are the steps I had to take:

• Go to the download website (http://dev.mysql.com/downloads/).
• Download the MySQL Community Server and install it (select the developer or full install, so it will install client and server tools).
• Open MySql Command Line Client from the Start menu.
• Enter your password used in install.

• In the prompt, mysql>, enter:

  CREATE DATABASE database_name;

  USE database_name;

  SOURCE myfile.sql

That should import your large file.

Same error can raise by mixing: tabs + spaces.

with open('/foo', 'w') as f:
 (spaces OR  tab) print f       <-- success
 (spaces AND tab) print f       <-- fail

@Eddie Loeffen's answer seems to be the most popular answer to this question, but it has some bad long term effects. If you review the documentation page for System.Net.ServicePointManager.SecurityProtocol here the remarks section implies that the negotiation phase should just address this (and forcing the protocol is bad practice because in the future, TLS 1.2 will be compromised as well). However, we wouldn't be looking for this answer if it did.

Researching, it appears that the ALPN negotiation protocol is required to get to TLS1.2 in the negotiation phase. We took that as our starting point and tried newer versions of the .Net framework to see where support starts. We found that .Net 4.5.2 does not support negotiation to TLS 1.2, but .Net 4.6 does.

So, even though forcing TLS1.2 will get the job done now, I recommend that you upgrade to .Net 4.6 instead. Since this is a PCI DSS issue for June 2016, the window is short, but the new framework is a better answer.

UPDATE: Working from the comments, I built this:

ServicePointManager.SecurityProtocol = 0;    
foreach (SecurityProtocolType protocol in SecurityProtocolType.GetValues(typeof(SecurityProtocolType)))
    {
        switch (protocol)
        {
            case SecurityProtocolType.Ssl3:
            case SecurityProtocolType.Tls:
            case SecurityProtocolType.Tls11:
                break;
            default:
                ServicePointManager.SecurityProtocol |= protocol;
            break;
        }
    }

In order to validate the concept, I or'd together SSL3 and TLS1.2 and ran the code targeting a server that supports only TLS 1.0 and TLS 1.2 (1.1 is disabled). With the or'd protocols, it seems to connect fine. If I change to SSL3 and TLS 1.1, that failed to connect. My validation uses HttpWebRequest from System.Net and just calls GetResponse(). For instance, I tried this and failed:

        HttpWebRequest request = WebRequest.Create("https://www.contoso.com/my/web/resource") as HttpWebRequest;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls11;
        request.GetResponse();

while this worked:

        HttpWebRequest request = WebRequest.Create("https://www.contoso.com/my/web/resource") as HttpWebRequest;
        ServicePointManager.SecurityProtocol = SecurityProtocolType.Ssl3 | SecurityProtocolType.Tls12;
        request.GetResponse();

This has an advantage over forcing TLS 1.2 in that, if the .Net framework is upgraded so that there are more entries in the Enum, they will be supported by the code as is. It has a disadvantage over just using .Net 4.6 in that 4.6 uses ALPN and should support new protocols if no restriction is specified.

Edit 4/29/2019 - Microsoft published this article last October. It has a pretty good synopsis of their recommendation of how this should be done in the various versions of .net framework.

Correct Answer:

function addDays(date, days) {
  var result = new Date(date);
  result.setDate(result.getDate() + days);
  return result;
}

Incorrect Answer:

This answer sometimes provides the correct result but very often returns the wrong year and month. The only time this answer works is when the date that you are adding days to happens to have the current year and month.

// Don't do it this way!
function addDaysWRONG(date, days) {
  var result = new Date();
  result.setDate(date.getDate() + days);
  return result;
}

As other users explained here about the usage of allowoveride directive, which is used to give permission to .htaccess usage. one thing I want to point out that never use allowoverride all if other users have access to write .htaccess instead use allowoveride as to permit certain modules.

Such as AllowOverride AuthConfig mod_rewrite Instead of

AllowOverride All

Because module like mod_mime can render your server side files as plain text.

In Bash you can also explicitly specify your redirects to different files:

cmd >log.out 2>log_error.out

Appending would be:

cmd >>log.out 2>>log_error.out

Someone would wonder how to set path in file urls.py, such as

domain/search/?q=CA

so that we could invoke query.

The fact is that it is not necessary to set such a route in file urls.py. You need to set just the route in urls.py:

urlpatterns = [
    path('domain/search/', views.CityListView.as_view()),
]

And when you input http://servername:port/domain/search/?q=CA. The query part '?q=CA' will be automatically reserved in the hash table which you can reference though

request.GET.get('q', None).

Here is an example (file views.py)

class CityListView(generics.ListAPIView):
    serializer_class = CityNameSerializer

    def get_queryset(self):
        if self.request.method == 'GET':
            queryset = City.objects.all()
            state_name = self.request.GET.get('q', None)
            if state_name is not None:
                queryset = queryset.filter(state__name=state_name)
            return queryset

In addition, when you write query string in the URL:

http://servername:port/domain/search/?q=CA

Do not wrap query string in quotes. For example,

http://servername:port/domain/search/?q="CA"

I encounter this issue when I first run LEMP on centos7 refer to this post.

I restart nginx to test the phpinfo page, but get this

http://xxx.xxx.xxx.xxx/info.php is not unreachable now.

Then I use tail -f /var/log/nginx/error.log to see more info. I find is the php-fpm.sock file not exist. Then I reboot the system, everything is OK.

Here may not need to reboot the system as Fath's post, just reload nginx and php-fpm.

restart php-fpm

reload nginx config

Create a UIImageView and add UIImage to it:

UIImageView *imageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"image Name"]] ;

Then add it to your view:

[self.view addSubView: imageView];

Try this, it works well on macOS:

$ brew uninstall --force yarn
$ npm uninstall -g yarn
$ yarn -v

v0.24.5 (or your current version)

$ which yarn

/usr/local/bin/yarn

$ rm -rf /usr/local/bin/yarn
$ rm -rf /usr/local/bin/yarnpkg
$ which yarn

yarn not found

$ brew install yarn 
$ brew link yarn
$ yarn -v

v1.17.3 (latest version)

yes you can by using static class. like this:

static class Global
{
    private static string _globalVar = "";

    public static string GlobalVar
    {
        get { return _globalVar; }
        set { _globalVar = value; }
    }
}

and for using any where you can write:

GlobalClass.GlobalVar = "any string value"

I suggest using Flexbox:

Be sure to add the proper vendor prefixes though!

form {_x000D_
  width: 400px;_x000D_
  border: 1px solid black;_x000D_
  display: flex;_x000D_
}_x000D_
_x000D_
input {_x000D_
  flex: 2;_x000D_
}_x000D_
_x000D_
input, label {_x000D_
  margin: 5px;_x000D_
}

<form method="post">_x000D_
  <label for="myInput">Sample label</label>_x000D_
  <input type="text" id="myInput" placeholder="Sample Input"/>_x000D_
</form>

the first case can also be easily done as:

A=A[0]

lscpu will list out these among other information regarding your CPU:

This is a fun solution with SQL Server 2005 that I like. I'm going to assume that by "for every record except for the first one", you mean that there is another "id" column that we can use to identify which row is "first".

SELECT id
    , field1
    , field2
    , field3
FROM
(
    SELECT id
        , field1
        , field2
        , field3
        , RANK() OVER (PARTITION BY field1, field2, field3 ORDER BY id ASC) AS [rank]
    FROM table_name
) a
WHERE [rank] > 1

Here´s how I do it:

    <plugin>
            <artifactId>maven-assembly-plugin</artifactId>
            <version>2.2</version>
            <configuration>
                <appendAssemblyId>false</appendAssemblyId>
                <descriptorRefs>
                    <descriptorRef>jar-with-dependencies</descriptorRef>
                </descriptorRefs>
                <archive>
                    <manifest>
                        <mainClass>com.project.MainClass</mainClass>
                    </manifest>
                </archive>
            </configuration>
        </plugin>

And then I just run:

mvn assembly:assembly

As there is nothing in this question (but its age) that requires a solution in Windows.Forms, here is a way to do this in WPF in code-behind.

TextBlock tb = new TextBlock();
tb.Inlines.Add(new Run("Background indicates packet repeat status:"));
tb.Inlines.Add(new LineBreak());
tb.Inlines.Add(new LineBreak());
Run r = new Run("White");
r.Background = Brushes.White;
r.ToolTip = "This word has a White background";
tb.Inlines.Add(r);
tb.Inlines.Add(new Run("\t= Identical Packet received at this time."));
tb.Inlines.Add(new LineBreak());
r = new Run("SkyBlue");
r.ToolTip = "This word has a SkyBlue background";
r.Background = new SolidColorBrush(Colors.SkyBlue);
tb.Inlines.Add(r);
tb.Inlines.Add(new Run("\t= Original Packet received at this time."));

myControl.Content = tb;

If you want the structure of a particular data table(dataTable1) with column headers (without data) into another data table(dataTable2), you can follow the below code:

        DataTable dataTable2 = dataTable1.Clone();
        dataTable2.Clear();

Now you can fill dataTable2 according to your condition. :)

GraalVM is a good choice. I've done Java+Javascript combination with GraalVM for microservice design (Java with Javascript reflection). They recently added support for python, I'd give it a try especially with how big its community has grown over the years.

Improving on this answer, I came up with these .gitconfig aliases:

branch-name = "symbolic-ref --short HEAD"
branch-remote-fetch = !"branch=$(git branch-name) && git config branch.\"$branch\".remote || echo origin #"
branch-remote-push  = !"branch=$(git branch-name) && git config branch.\"$branch\".pushRemote || git config remote.pushDefault || git branch-remote-fetch #"
branch-url-fetch = !"remote=$(git branch-remote-fetch) && git remote get-url        \"$remote\" #"  # cognizant of insteadOf
branch-url-push  = !"remote=$(git branch-remote-push ) && git remote get-url --push \"$remote\" #"  # cognizant of pushInsteadOf

The other answers here are correct, but they don't get into how instanceof actually works, which may be of interest to some language lawyers out there.

Every object in JavaScript has a prototype, accessible through the __proto__ property. Functions also have a prototype property, which is the initial __proto__ for any objects created by them. When a function is created, it is given a unique object for prototype. The instanceof operator uses this uniqueness to give you an answer. Here's what instanceof might look like if you wrote it as a function.

function instance_of(V, F) {
  var O = F.prototype;
  V = V.__proto__;
  while (true) {
    if (V === null)
      return false;
    if (O === V)
      return true;
    V = V.__proto__;
  }
}

This is basically paraphrasing ECMA-262 edition 5.1 (also known as ES5), section 15.3.5.3.

Note that you can reassign any object to a function's prototype property, and you can reassign an object's __proto__ property after it is constructed. This will give you some interesting results:

function F() { }
function G() { }
var p = {};
F.prototype = p;
G.prototype = p;
var f = new F();
var g = new G();

f instanceof F;   // returns true
f instanceof G;   // returns true
g instanceof F;   // returns true
g instanceof G;   // returns true

F.prototype = {};
f instanceof F;   // returns false
g.__proto__ = {};
g instanceof G;   // returns false

Without use ID (<tbody id="tbodyid">) , it is a great way to cope with this issue

$('#table1').find("tr:gt(0)").remove();

PS:To remove specific row number as following example

$('#table1 tr').eq(1).remove();

or

$('#tr:nth-child(2)').remove();

A much better way is to use inline-block, because you don't need to use clear:both at the end of your list anymore.

Try this:

<ul>
    <li>
        <a href="#">some item</a>
    </li>
    <li>
        <a href="#">another item</a>
    </li>
</ul>

CSS:

ul > li{
    display:inline-block;
}

Have a look at it here : http://jsfiddle.net/shahverdy/4N6Ap/

A vertical tab was the opposite of a line feed i.e. it went upwards by one line. It had nothing to do with tab positions. If you want to prove this, try it on an RS232 terminal.

The two functions below I have found to be very useful when dealing with many variable testing cases.

def nz(value, none_value, strict=True):
    ''' This function is named after an old VBA function. It returns a default
        value if the passed in value is None. If strict is False it will
        treat an empty string as None as well.

        example:
        x = None
        nz(x,"hello")
        --> "hello"
        nz(x,"")
        --> ""
        y = ""   
        nz(y,"hello")
        --> ""
        nz(y,"hello", False)
        --> "hello" '''

    if value is None and strict:
        return_val = none_value
    elif strict and value is not None:
        return_val = value
    elif not strict and not is_not_null(value):
        return_val = none_value
    else:
        return_val = value
    return return_val 

def is_not_null(value):
    ''' test for None and empty string '''
    return value is not None and len(str(value)) > 0

Easiest way:

// Prefs.h
#define PREFS_MY_CONSTANT @"prefs_my_constant"

Better way:

// Prefs.h
extern NSString * const PREFS_MY_CONSTANT;

// Prefs.m
NSString * const PREFS_MY_CONSTANT = @"prefs_my_constant";

One benefit of the second is that changing the value of a constant does not cause a rebuild of your entire program.

You can set up your element with

value="@model.productId"

and

onclick= addToWishList(this.value);

This is working for me on Centos

First: in file /etc/httpd/conf/httpd.conf

add

Listen 8079 

after

Listen 80

This till your server to listen to the port 8079

Second: go to your virtual host for ex. /etc/httpd/conf.d/vhost.conf

and add this code below

<VirtualHost *:8079>
   DocumentRoot /var/www/html/api_folder
   ServerName example.com
   ServerAlias www.example.com
   ServerAdmin [email protected]
   ErrorLog logs/www.example.com-error_log
   CustomLog logs/www.example.com-access_log common
</VirtualHost>

This mean when you go to your www.example.com:8079 redirect to

/var/www/html/api_folder

But you need first to restart the service

sudo service httpd restart

Whilst this an old question, I ran into this problem myself recently and some of the answers here are now deprecated (as the comments point out). So for the benefit of others who may have stumbled here:

A term query can be used to find the exact term specified in the reverse index:

{
  "query": {
   "term" : { "tags" : "a" }
} 

From the documenation https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-term-query.html

Alternatively you can use a terms query, which will match all documents with any of the items specified in the given array:

{
  "query": {
   "terms" : { "tags" : ["a", "c"]}
} 

https://www.elastic.co/guide/en/elasticsearch/reference/current/query-dsl-terms-query.html

One gotcha to be aware of (which caught me out) - how you define the document also makes a difference. If the field you're searching in has been indexed as a text type then Elasticsearch will perform a full text search (i.e using an analyzed string).

If you've indexed the field as a keyword then a keyword search using a 'non-analyzed' string is performed. This can have a massive practical impact as Analyzed strings are pre-processed (lowercased, punctuation dropped etc.) See (https://www.elastic.co/guide/en/elasticsearch/guide/master/term-vs-full-text.html)

To avoid these issues, the string field has split into two new types: text, which should be used for full-text search, and keyword, which should be used for keyword search. (https://www.elastic.co/blog/strings-are-dead-long-live-strings)

If you want customer's details that customer had entered while ordering, then you can use the following code:

$order = new WC_Order($order_id);
$billing_address = $order->get_billing_address();
$billing_address_html = $order->get_formatted_billing_address();

// For printing or displaying on the web page
$shipping_address = $order->get_shipping_address();
$shipping_address_html = $order->get_formatted_shipping_address(); // For printing or displaying on web page

Apart from this, $customer = new WC_Customer( $order_id ); can not get you customer details.

First of all, new WC_Customer() doesn't take any arguments.

Secondly, WC_Customer will get customer's details only when the user is logged in and he/she is not on the admin side. Instead he/she should be on website's front-end like the 'My Account', 'Shop', 'Cart', or 'Checkout' page.

The following example centers a frame on the screen:

package com.zetcode;

import java.awt.Dimension;
import java.awt.EventQueue;
import java.awt.GraphicsEnvironment;
import java.awt.Point;
import javax.swing.JFrame;


public class CenterOnScreen extends JFrame {

    public CenterOnScreen() {

        initUI();
    }

    private void initUI() {

        setSize(250, 200);
        centerFrame();
        setTitle("Center");
        setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    }

    private void centerFrame() {

            Dimension windowSize = getSize();
            GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
            Point centerPoint = ge.getCenterPoint();

            int dx = centerPoint.x - windowSize.width / 2;
            int dy = centerPoint.y - windowSize.height / 2;    
            setLocation(dx, dy);
    }


    public static void main(String[] args) {
        EventQueue.invokeLater(new Runnable() {
            @Override
            public void run() {
                CenterOnScreen ex = new CenterOnScreen();
                ex.setVisible(true);
            }
        });       
    }
}

In order to center a frame on a screen, we need to get the local graphics environment. From this environment, we determine the center point. In conjunction with the frame size, we manage to center the frame. The setLocation() is the method that moves the frame to the central position.

Note that this is actually what the setLocationRelativeTo(null) does:

public void setLocationRelativeTo(Component c) {
    // target location
    int dx = 0, dy = 0;
    // target GC
    GraphicsConfiguration gc = getGraphicsConfiguration_NoClientCode();
    Rectangle gcBounds = gc.getBounds();

    Dimension windowSize = getSize();

    // search a top-level of c
    Window componentWindow = SunToolkit.getContainingWindow(c);
    if ((c == null) || (componentWindow == null)) {
        GraphicsEnvironment ge = GraphicsEnvironment.getLocalGraphicsEnvironment();
        gc = ge.getDefaultScreenDevice().getDefaultConfiguration();
        gcBounds = gc.getBounds();
        Point centerPoint = ge.getCenterPoint();
        dx = centerPoint.x - windowSize.width / 2;
        dy = centerPoint.y - windowSize.height / 2;
    }

  ...

  setLocation(dx, dy);
}

The runas command does not allow a password on its command line. This is by design (and also the reason you cannot pipe a password to it as input). Raymond Chen says it nicely:

The RunAs program demands that you type the password manually. Why doesn't it accept a password on the command line?

This was a conscious decision. If it were possible to pass the password on the command line, people would start embedding passwords into batch files and logon scripts, which is laughably insecure.

In other words, the feature is missing to remove the temptation to use the feature insecurely.

dynamically allocate some memory using new:

int* array = new int[SIZE];

Somewhere the code--either your code or a jQuery plugin--is calling $.browser to get the current browser type.

However, early has year the $.browser function was deprecated. Since then some bugs have been filed against it but because it is deprecated, the jQuery team has decided not to fix them. I've decided not to rely on the function at all.

I don't see any references to $.browser in your code, so the problem probably lies in one of your plugins. To find it, look at the source code for each plugin that you've referenced with a <script> tag.

As for how to fix it: well, it depends on the context. E.g., maybe there's an updated version of the problematic plugin. Or perhaps you can use another plugin that does something similar but doesn't depend on $.browser.

first need to get actual constrain name by this query

SHOW CREATE TABLE TABLE_NAME

This query will result constrain name of the foreign key, now below query will drop it.

ALTER TABLE TABLE_NAME DROP FOREIGN KEY COLUMN_NAME_ibfk_1

last number in above constrain name depends how many foreign keys you have in table

What are you trying to accomplish? If it's customization then you have a set of files to work with though that seems like a bad idea. Otherwise, I would suggest going with the full build of v4.1.x since that is the current release.

I had this problem on devices running iOS. I made a shop that is embeddable in a normal website using an iframe. Somehow, on every pageload the user got a new sessionid, resulting in users getting stuck halfway the process because some values weren't present in the session.

I tried some of the solutions given on this page, but popups don't work very well on an iPad and I needed the most transparent solution.

I resolved it using a redirect. The website that embeds my site must first redirect the user to my site, so the top frame contains the url to my site, where I set a cookie and redirect the user to the proper page on the website that embeds my site, that is passed through in the url.

Example PHP code

Remote website redirects user to

http://clientname.example.com/init.php?redir=http://www.domain.com/shop/frame

init.php

<?php
// set a cookie for a year
setcookie('initialized','1',time() + 3600 * 24 * 365, '/', '.domain.com', false, false);
header('location: ' . $_GET['redir']);
die;

The user ends up on http://www.domain.com/shop/frame where my site is embedded, storing sessions as it should and eating cookies.

Hope this helps someone.

Ok, here's what I've got in my app. It includes a hack to prevent ListViews from going black while scrolling.

1) Best practice is to make new javascript file like my.js. Make this file into your js folder in root directory -> js/my.js . 2) In my.js file add your code inside of $(document).ready(function(){}) scope.

$(document).ready(function(){
    $(".icon-bg").click(function () {
        $(".btn").toggleClass("active");
        $(".icon-bg").toggleClass("active");
        $(".container").toggleClass("active");
        $(".box-upload").toggleClass("active");
        $(".box-caption").toggleClass("active");
        $(".box-tags").toggleClass("active");
        $(".private").toggleClass("active");
        $(".set-time-limit").toggleClass("active");
        $(".button").toggleClass("active");
    });

    $(".button").click(function () {
        $(".button-overlay").toggleClass("active");
    });

    $(".iconmelon").click(function () {
        $(".box-upload-ing").toggleClass("active");
        $(".iconmelon-loaded").toggleClass("active");
    });

    $(".private").click(function () {
        $(".private-overlay").addClass("active");
        $(".private-overlay-wave").addClass("active");
    });
});

3) add your new js file into your html

<head>
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.3/jquery.min.js"></script>
<script src="/js/my.js"></script>
</head>

the simplest way to copy a List is to pass it to the constructor of the new list:

List<String> b = new ArrayList<>(a);

b will be a shallow copy of a

Looking at the source of Collections.copy(List,List) (I'd never seen it before) it seems to be for coping the elements index by index. using List.set(int,E) thus element 0 will over write element 0 in the target list etc etc. Not particularly clear from the javadocs I'd have to admit.

List<String> a = new ArrayList<>(a);
a.add("foo");
b.add("bar");

List<String> b = new ArrayList<>(a); // shallow copy 'a'

// the following will all hold
assert a.get(0) == b.get(0);
assert a.get(1) == b.get(1);
assert a.equals(b);
assert a != b; // 'a' is not the same object as 'b'

No submodule mapping found in .gitmodules for path 'OtherLibrary/MKStore' when

I didn't know why the error occur. After spending a minute and found the answer in stackoverflow.

$ git rm --cached OtherLibrary/MKStore

and then update the submodule again. It's working fine.

Instead of

formGroupName="i"

You must use:

[formGroupName]="i"

Tips:

Since you're looping over the controls, you've already the variable area, so you can replace this:

*ngIf="areasForm.get('areas').controls[i].name.hasError('required')"

*ngIf="area.hasError('required', 'name')"

There are a couple of ways.

One is to add this.onToggleLoop = this.onToggleLoop.bind(this); in the constructor.

Another is arrow functions onToggleLoop = (event) => {...}.

And then there is onClick={this.onToggleLoop.bind(this)}.

you can use the <text> tag for both cshtml code with javascript

    public class Example1 extends FragmentActivity {

        @Override
        protected void onCreate(Bundle savedInstanceState) {
            super.onCreate(savedInstanceState);
          DemoFragment fragmentDemo = (DemoFragment) 
          getSupportFragmentManager().findFragmentById(R.id.frame_container);
          //above part is to determine which fragment is in your frame_container
          setFragment(fragmentDemo);
                       (OR)
          setFragment(new TestFragment1());
        }

        // This could be moved into an abstract BaseActivity 
        // class for being re-used by several instances
        protected void setFragment(Fragment fragment) {
            FragmentManager fragmentManager = getSupportFragmentManager();
            FragmentTransaction fragmentTransaction = 
                fragmentManager.beginTransaction();
            fragmentTransaction.replace(android.R.id.content, fragment);
            fragmentTransaction.commit();
        }
    }

To add a fragment into a Activity or FramentActivity it requires a Container. That container should be a "Framelayout", which can be included in xml or else you can use the default container for that like "android.R.id.content" to remove or replace a fragment in Activity.

main.xml

<RelativeLayout
    android:layout_width="match_parent"
    android:layout_height="match_parent" >
 <!-- Framelayout to display Fragments -->
   <FrameLayout
        android:id="@+id/frame_container"
        android:layout_width="match_parent"
        android:layout_height="match_parent" />

    <ImageView
        android:id="@+id/imagenext"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_alignParentRight="true"
        android:layout_margin="16dp"
        android:src="@drawable/next" />
</RelativeLayout>

++i is slightly more efficient due to its semantics:

++i;  // Fetch i, increment it, and return it
i++;  // Fetch i, copy it, increment i, return copy

For int-like indices, the efficiency gain is minimal (if any). For iterators and other heavier-weight objects, avoiding that copy can be a real win (particularly if the loop body doesn't contain much work).

As an example, consider the following loop using a theoretical BigInteger class providing arbitrary precision integers (and thus some sort of vector-like internals):

std::vector<BigInteger> vec;
for (BigInteger i = 0; i < 99999999L; i++) {
  vec.push_back(i);
}

That i++ operation includes copy construction (i.e. operator new, digit-by-digit copy) and destruction (operator delete) for a loop that won't do anything more than essentially make one more copy of the index object. Essentially you've doubled the work to be done (and increased memory fragmentation most likely) by simply using the postfix increment where prefix would have been sufficient.

As far as I know, you can't ask apt for what their current sources are. However, you can do what you want using shell tools.

Getting a list of repositories:

grep -h ^deb /etc/apt/sources.list /etc/apt/sources.list.d/* >> current.repos.list

Applying the list:

apt-add-repository << current.repos.list

Regarding getting the repository from a package (installed or available), this will do the trick:

apt-cache policy package_name | grep -m1 http | awk '{ print $2 " " $3 }'

However, that will show you the repository of the latest version available of that package, and you may have more repositories for the same package with older versions. Remove all the grep/awk stuff if you want to see the full list.

Try this, its simple : **speakout.xml : **

<?xml version="1.0" encoding="utf-8"?>
<LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
android:layout_width="match_parent"
android:layout_height="match_parent"
android:background="#3498db"
android:weightSum="1"
android:orientation="vertical" >
<TextView
android:id="@+id/txtheader"
android:layout_width="match_parent"
android:layout_height="0dp"
android:layout_gravity="center"
android:layout_weight=".1"
android:gravity="center"
android:padding="3dp"
android:text="Speak Out!!!"
android:textColor="#fff"
android:textSize="25sp"
android:textStyle="bold" />
<EditText
android:id="@+id/edtTexttoSpeak"
android:layout_width="match_parent"
android:layout_weight=".5"
android:background="#fff"
android:textColor="#2c3e50"
android:text="Hi there!!!"
android:padding="5dp"
android:gravity="top|left"

android:text="SPEAK OUT"/>
</LinearLayout>

And Your SpeakOut.java :

import android.app.Activity;

    setContentView(R.layout.speakout);
    btnspeakout = (Button) findViewById(R.id.btnspeakout);
    edtTexttoSpeak = (EditText) findViewById(R.id.edtTexttoSpeak);
    repeatTTS = new TextToSpeech(this, this);
    btnspeakout.setOnClickListener(new View.OnClickListener() {
        @Override

            repeatTTS.speak(edtTexttoSpeak.getText().toString(),

        }
    });
}

@Override

        // TODO Auto-generated method stub
    }
}

Try like

$('.printMe').click(function(){
     window.print();
});

or if you want to print selected area try like

$('.printMe').click(function(){
     $("#outprint").print();
});

footerText {
    line-height: 20px;
}

you don't need to start playing with position or even layout of other elements... use this simple solution

>>> class A(object): pass

>>> e = A()
>>> e
<__main__.A object at 0xb6d464ec>
>>> print type(e)
<class '__main__.A'>
>>> print type(e).__name__
A
>>> 

what do you mean by convert into a string? you can define your own repr and str_ methods:

>>> class A(object):
    def __repr__(self):
        return 'hei, i am A or B or whatever'

>>> e = A()
>>> e
hei, i am A or B or whatever
>>> str(e)
hei, i am A or B or whatever

or i dont know..please add explainations ;)

The line (or lines) between the lines beginning <<<<<<< and ====== here:

<<<<<<< HEAD:file.txt
Hello world
=======

... is what you already had locally - you can tell because HEAD points to your current branch or commit. The line (or lines) between the lines beginning ======= and >>>>>>>:

=======
Goodbye
>>>>>>> 77976da35a11db4580b80ae27e8d65caf5208086:file.txt

... is what was introduced by the other (pulled) commit, in this case 77976da35a11. That is the object name (or "hash", "SHA1sum", etc.) of the commit that was merged into HEAD. All objects in git, whether they're commits (version), blobs (files), trees (directories) or tags have such an object name, which identifies them uniquely based on their content.

I agree with Shivam's answer except for textract doesn't exist for windows. And, for some reason antiword also fails to read the '.doc' files and gives an error:

'filename.doc' is not a word document. # This happens when the file wasn't generated via MS Office. Eg: Web-pages may be stored in .doc format offline.

So, I've got the following workaround to extract the text:

from bs4 import BeautifulSoup as bs
soup = bs(open(filename).read())
[s.extract() for s in soup(['style', 'script'])]
tmpText = soup.get_text()
text = "".join("".join(tmpText.split('\t')).split('\n')).encode('utf-8').strip()
print text

This script will work with most kinds of files. Have fun!

You can also use util library:

const util = require("util")

> myObject = {1:2, 3:{5:{6:{7:8}}}}
{ '1': 2, '3': { '5': { '6': [Object] } } }

> util.inspect(myObject, {showHidden: true, depth: null})
"{\n  '1': 2,\n  '3': { '5': { '6': { '7': 8 } } }\n}"

> JSON.stringify(myObject)
'{"1":2,"3":{"5":{"6":{"7":8}}}}'

To fully answer this question in 2020, let me quote several statements from official Python docs:

Changed in version 3.7: Dictionary order is guaranteed to be insertion order. This behavior was an implementation detail of CPython from 3.6.

Changed in version 3.7: Dictionary order is guaranteed to be insertion order.

Changed in version 3.8: Dictionaries are now reversible.

Dictionaries and dictionary views are reversible.

A statement regarding OrderedDict vs Dict:

Ordered dictionaries are just like regular dictionaries but have some extra capabilities relating to ordering operations. They have become less important now that the built-in dict class gained the ability to remember insertion order (this new behavior became guaranteed in Python 3.7).

What you are looking for is called Model persistence in sklearn words and it is documented in introduction and in model persistence sections.

So you have initialized your classifier and trained it for a long time with

clf = some.classifier()
clf.fit(X, y)

After this you have two options:

1) Using Pickle

import pickle
# now you can save it to a file
with open('filename.pkl', 'wb') as f:
    pickle.dump(clf, f)

# and later you can load it
with open('filename.pkl', 'rb') as f:
    clf = pickle.load(f)

2) Using Joblib

from sklearn.externals import joblib
# now you can save it to a file
joblib.dump(clf, 'filename.pkl') 
# and later you can load it
clf = joblib.load('filename.pkl')

One more time it is helpful to read the above-mentioned links

I have the same issue in [email protected], and it because the extra slash in the end of regex route:

.when('/goods/publish/:classId/', option)

to

.when('/goods/publish/:classId', option)

and it works correctly.

As per @Randal comment, you can use perl, e.g.

$ printf 5a5a5a5a | perl -lne 'print pack "H*", $_'
ZZZZ

and other way round:

$ printf ZZZZ | perl -lne 'print unpack "H*", $_'
5a5a5a5a

Another example with file:

$ printf 5a5a5a5a | perl -lne 'print pack "H*", $_' > file.bin
$ perl -lne 'print unpack "H*", $_' < file.bin
5a5a5a5a

Others mentioned django-phonenumber-field. To get the display format how you want you need to set PHONENUMBER_DEFAULT_FORMAT setting to "E164", "INTERNATIONAL", "NATIONAL", or "RFC3966", however you want it displayed. See the GitHub source.

All the 3 first ways are identical. You have make sure that if t is a matrix you add . before using multiplication or the power.

for matrix:

t= [1 2 3;2 3 4;3 4 5];
tp=t.*t;
x=exp(-(t.^2));
y=exp(-(t.*t));
z=exp(-(tp));

gives the results:

x =

0.3679    0.0183    0.0001
0.0183    0.0001    0.0000
0.0001    0.0000    0.0000

y =

0.3679    0.0183    0.0001
0.0183    0.0001    0.0000
0.0001    0.0000    0.0000

z=

0.3679    0.0183    0.0001
0.0183    0.0001    0.0000
0.0001    0.0000    0.0000

And using a scalar:

p=3;
pp=p^2;
x=exp(-(p^2));
y=exp(-(p*p));
z=exp(-pp);

gives the results:

x =

1.2341e-004

y =

1.2341e-004

z =

1.2341e-004

Try this:

$("a").removeAttr('href');

EDIT-

From your updated code:

 var location= $('#link1').attr("href");
 $("#link1").removeAttr('href');
 $('ul').addClass('expanded');
 $('ul.expanded').fadeIn(300);
 $("#link1").attr("href", location);

You can use Httpful :

Here is another simple solution using sed.

$ sed -i 's/all.*/& anotherthing/g' filename.txt

Explanation:

all.* means all lines started with 'all'.

& represent the match (ie the complete line that starts with 'all')

then sed replace the former with the later and appends the ' anotherthing' word

To select content use Alt + Shift + Up arrow

To select content up to the next wrapping block press this shortcut again

To go back one step press Alt + Shift + Down arrow. This is also a useful shortcut when you need to select content in a complex expression and do not want to miss something.

Get the first character of a bare python string:

>>> mystring = "hello"
>>> print(mystring[0])
h
>>> print(mystring[:1])
h
>>> print(mystring[3])
l
>>> print(mystring[-1])
o
>>> print(mystring[2:3])
l
>>> print(mystring[2:4])
ll

Get the first character from a string in the first position of a python list:

>>> myarray = []
>>> myarray.append("blah")
>>> myarray[0][:1]
'b'
>>> myarray[0][-1]
'h'
>>> myarray[0][1:3]
'la'

Many people get tripped up here because they are mixing up operators of Python list objects and operators of Numpy ndarray objects:

Numpy operations are very different than python list operations.

Wrap your head around the two conflicting worlds of Python's "list slicing, indexing, subsetting" and then Numpy's "masking, slicing, subsetting, indexing, then numpy's enhanced fancy indexing".

These two videos cleared things up for me:

"Losing your Loops, Fast Numerical Computing with NumPy" by PyCon 2015: https://youtu.be/EEUXKG97YRw?t=22m22s

"NumPy Beginner | SciPy 2016 Tutorial" by Alexandre Chabot LeClerc: https://youtu.be/gtejJ3RCddE?t=1h24m54s

I would use one Object and one Array, if you want to save some cycle:

var lookup = {};
var items = json.DATA;
var result = [];

for (var item, i = 0; item = items[i++];) {
  var name = item.name;

  if (!(name in lookup)) {
    lookup[name] = 1;
    result.push(name);
  }
}

In this way you're basically avoiding the indexOf / inArray call, and you will get an Array that can be iterate quicker than iterating object's properties – also because in the second case you need to check hasOwnProperty.

Of course if you're fine with just an Object you can avoid the check and the result.push at all, and in case get the array using Object.keys(lookup), but it won't be faster than that.

There is a handy tool which saves a lot of time at

http://tools.perceptus.ca/text-wiz.php?ops=7

You just have to feed in the table name, field names and the data - tab separated and hit Go!

zvolkov's answer is the perfect one to find out if there is such a customer. If you need to use the customer afterwards, you can do:

Customer customer = list.FirstOrDefault(cus => cus.FirstName == "John");
if (customer != null)
{
    // Use customer
}

I know this isn't what you were asking, but I thought I'd pre-empt a follow-on question :) (Of course, this only finds the first such customer... to find all of them, just use a normal where clause.)

This change only first handle in multihandle slider. In apiDoc you can see:"For example, if you specify values: [ 1, 5, 18 ] and create one custom handle, the plugin will create the other two."

Looking at the NSPredicate reference, it looks like you need to surround your substitution character with quotes. For example, your current predicate reads: (SPORT == Football) You want it to read (SPORT == 'Football'), so your format string needs to be @"(SPORT == '%@')".

I'm from Brazil and I create my data bases using latin1_spanish_ci. For the html and everything else I use:

charset=ISO-8859-1

The data goes right with é,ã and ç... Sometimes I have to put the texts of the html using the code of it, such as:

Olá

gives me

Olá

You can find the codes in this page: http://www.ascii.cl/htmlcodes.htm

Hope this helps. I remember it was REALLY annoying.

I found that you don't necessarily need the text vertically centred, it also looks good near the bottom of the row, it's only when it's at the top (or above centre?) that it looks wrong. So I went with this to push the links to the bottom of the row:

.navbar-brand {
    min-height: 80px;
}

@media (min-width: 768px) {
    #navbar-collapse {
        position: absolute;
        bottom: 0px;
        left: 250px;
    }
}

My brand image is SVG and I used height: 50px; width: auto which makes it about 216px wide. It spilled out of its container vertically so I added the min-height: 80px; to make room for it plus bootstrap's 15px margins. Then I tweaked the navbar-collapse's left setting until it looked right.

The standard solution:

 expr $d1 - $d2

You can also do:

echo $(( d1 - d2 ))

but beware that this will treat 07 as an octal number! (so 07 is the same as 7, but 010 is different than 10).

You can also use Control-a + H to save loggings into screenlog.n file. One more Control-a + H to turn off.

C-a H: Begins/ends logging of the current window to the file "screenlog.n".

# If you want to edit the file in-place
sed -i -e 's/^/prefix/' file

# If you want to create a new file
sed -e 's/^/prefix/' file > file.new

If prefix contains /, you can use any other character not in prefix, or escape the /, so the sed command becomes

's#^#/opt/workdir#'
# or
's/^/\/opt\/workdir/'

ArrayList<Matrices> list = new ArrayList<Matrices>();
list.add( new Matrices(1,1,10) );
list.add( new Matrices(1,2,20) );

All u need do is to change the lowercase 'hh' in the pattern to an uppercase letter 'HH'

for Kotlin:

val sdf = SimpleDateFormat("yyyy-MM-dd HH:mm:ss") val currentDate = sdf.format(Date())

for java:

SimpleDateFormat sdf = new SimpleDateFormat("yyyy-MM-ddHH:mm:ss") Date currentDate = sdf.format(new Date())
