This is for vmware workstation 6.5

It is pretty far down.

select Create new virtual machine -> select custom ->
on compatibility page take defaults ->
check I will install os later -> click through several pages choosing other for OS, give it a name, make sure it IS NOT in the same folder as the VMDK file. Choose bridged network.

You will now see a screen asking to select disk, select existing virual disk. then browse and select the VMDK file

Here you can see that not x == y has one more instruction than x != y. So the performance difference will be very small in most cases unless you are doing millions of comparisons and even then this will likely not be the cause of a bottleneck.

getElementById will return false if the element was not found in the DOM.

var el = document.getElementById("customx");
if (el !== null && el.value === "")
{
  //The element was found and the value is empty.
}

This will work fine with Linq to Objects. However, some LINQ providers have difficulty running CLR methods as part of the query. This is expecially true of some database providers.

The problem is that the DB providers try to move and compile the LINQ query as a database query, to prevent pulling all of the objects across the wire. This is a good thing, but does occasionally restrict the flexibility in your predicates.

Unfortunately, without checking the provider documentation, it's difficult to always know exactly what will or will not be supported directly in the provider. It looks like your provider allows comparisons, but not the string check. I'd guess that, in your case, this is probably about as good of an approach as you can get. (It's really not that different from the IsNullOrEmpty check, other than creating the "string.Empty" instance for comparison, but that's minor.)

: | git mktree | git diff --shortstat --stdin

Or:

git ls-tree @ | sed '1i\\' | git mktree --batch | xargs | git diff-tree --shortstat --stdin

You can use String =~ Regex. It returns position of full regex match in string.

irb> ("abc" =~ %r"abc") == 0
=> true
irb> ("aabc" =~ %r"abc") == 0
=> false

You are able to cut all odd/even columns by using seq:

This would print all odd columns

echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(seq -s, 1 2 10)

To print all even columns you could use

echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(seq -s, 2 2 10)

By changing the second number of seq you can specify which columns to be printed.

If the specification which columns to print is more complex you could also use a "one-liner-if-clause" like

echo 1,2,3,4,5,6,7,8,9,10 | cut -d, -f$(for i in $(seq 1 10); do if [[ $i -lt 10 && $i -lt 5 ]];then echo -n $i,; else echo -n $i;fi;done)

This would print all columns from 1 to 5 - you can simply modify the conditions to create more complex conditions to specify weather a column shall be printed.

You could try this, but performance may be worse a little:

@Dao
public abstract class TourDao {

    @Query("SELECT * FROM Tour WHERE id == :id")
    public abstract Tour getTour(int id);

    @Update
    public abstract int updateTour(Tour tour);

    public void updateTour(int id, String end_address) {
        Tour tour = getTour(id);
        tour.end_address = end_address;
        updateTour(tour);
    }
}

edit: it's currently 2016-09-24, and PHP 5.4 has been released 2012-03-01, and support has ended 2015-09-01. Still, this answer seems to gain upvotes. If you're still using PHP < 5.4, your are creating a security risk and endagering your project. If you have no compelling reasons to stay at <5.4, or even already use version >= 5.4, do not use this answer, and just use PHP>= 5.4 (or, you know, a recent one) and implement the JsonSerializable interface

You would define a function, for instance named getJsonData();, which would return either an array, stdClass object, or some other object with visible parameters rather then private/protected ones, and do a json_encode($data->getJsonData());. In essence, implement the function from 5.4, but call it by hand.

Something like this would work, as get_object_vars() is called from inside the class, having access to private/protected variables:

function getJsonData(){
    $var = get_object_vars($this);
    foreach ($var as &$value) {
        if (is_object($value) && method_exists($value,'getJsonData')) {
            $value = $value->getJsonData();
        }
    }
    return $var;
}

Try javax.net.ssl.keyStorePassword instead of javax.net.ssl.keyPassword: the latter isn't mentioned in the JSSE ref guide.

The algorithms you mention should be there by default using the default security providers. NoSuchAlgorithmExceptions are often cause by other underlying exceptions (file not found, wrong password, wrong keystore type, ...). It's useful to look at the full stack trace.

You could also use -Djavax.net.debug=ssl, or at least -Djavax.net.debug=ssl,keymanager, to get more debugging information, if the information in the stack trace isn't sufficient.

Swift 3.0

if let url = URL(string: "https://www.reddit.com") {
    if #available(iOS 10.0, *) {
        UIApplication.shared.open(url, options: [:])
    } else {
        UIApplication.shared.openURL(url)
    }

This supports devices running older versions of iOS as well

Typecast the envelope to SoapPrimitive:

SoapPrimitive result = (SoapPrimitive)envelope.getResponse();
String strRes = result.toString();

and it will work.

public int read(byte[] a) throws IOException {
    try {
        return in.read(a);
    } catch (final Throwable t) {
        /* can do something here, like  in=null;  */
        throw t;
    }
}

This is a concrete example where the method throws an IOException. The final means t can only hold an exception thrown from the try block. Additional reading material can be found here and here.

I came here to learn how to create a function pointer (not a method pointer) from a method but none of the answers here provide a solution. Here is what I came up with:

template <class T> struct MethodHelper;
template <class C, class Ret, class... Args> struct MethodHelper<Ret (C::*)(Args...)> {
    using T = Ret (C::*)(Args...);
    template <T m> static Ret call(C* object, Args... args) {
        return (object->*m)(args...);
    }
};

#define METHOD_FP(m) MethodHelper<decltype(m)>::call<m>

So for your example you would now do:

Dog dog;
using BarkFunction = void (*)(Dog*);
BarkFunction bark = METHOD_FP(&Dog::bark);
(*bark)(&dog); // or simply bark(&dog)

Edit:
Using C++17, there is an even better solution:

template <auto m> struct MethodHelper;
template <class C, class Ret, class... Args, Ret (C::*m)(Args...)> struct MethodHelper<m> {
    static Ret call(C* object, Args... args) {
        return (object->*m)(args...);
    }
};

which can be used directly without the macro:

Dog dog;
using BarkFunction = void (*)(Dog*);
BarkFunction bark = MethodHelper<&Dog::bark>::call;
(*bark)(&dog); // or simply bark(&dog)

For methods with modifiers like const you might need some more specializations like:

template <class C, class Ret, class... Args, Ret (C::*m)(Args...) const> struct MethodHelper<m> {
    static Ret call(const C* object, Args... args) {
        return (object->*m)(args...);
    }
};

In addition to other answers need to add that parameters not only helps prevent sql injection but can improve performance of queries. Sql server caching parameterized query plans and reuse them on repeated queries execution. If you not parameterized your query then sql server would compile new plan on each query(with some exclusion) execution if text of query would differ.

For anyone who came here trying find out how to set connection string dinamicaly, and got trouble with the solutions above (like "Format of the initialization string does not conform to specification starting at index 0.") when setting up the connection string in the constructor. This is how to fix it:

public static string ConnectionString
{
    get {
        if (ConfigurationManager.AppSettings["DevelopmentEnvironment"] == "true")
            return ConfigurationManager.ConnectionStrings["LocalDb"].ConnectionString;
        else
            return ConfigurationManager.ConnectionStrings["ExternalDb"].ConnectionString;
    }
}

public ApplicationDbContext() : base(ConnectionString)
{
}

As an ArrayList that line would be

import java.util.ArrayList;
...
ArrayList<Card> hand = new ArrayList<Card>();

To use the ArrayList you have do

hand.get(i); //gets the element at position i 
hand.add(obj); //adds the obj to the end of the list
hand.remove(i); //removes the element at position i
hand.add(i, obj); //adds the obj at the specified index
hand.set(i, obj); //overwrites the object at i with the new obj

Also read this http://docs.oracle.com/javase/6/docs/api/java/util/ArrayList.html

In each parent LinearLayout for which you want dividers between components, add android:divider="?android:dividerHorizontal" or android:divider="?android:dividerVertical.

Choose appropriate between them as per orientation of your LinearLayout.

Till I know, this resource style is added from Android 4.3.

If one or both of the files you wish to compare isn't in an Eclipse project:

1. Open the Quick Access search box

   • Linux/Windows: Ctrl+3
   • Mac: ?+3

2. Type compare and select Compare With Other Resource

3. Select the files to compare ? OK

You can also create a keyboard shortcut for Compare With Other Resource by going to Window ? Preferences ? General ? Keys

For future reference, this can also happen if npm is down. That's how I found this question. Wish the first npm task was a server status check so there was a clearer error message.

The way that the language manages lexical scope creates issues with including both goto and continue. For example,

local a=0
repeat 
    if f() then
        a=1 --change outer a
    end
    local a=f() -- inner a
until a==0 -- test inner a

The declaration of local a inside the loop body masks the outer variable named a, and the scope of that local extends across the condition of the until statement so the condition is testing the innermost a.

If continue existed, it would have to be restricted semantically to be only valid after all of the variables used in the condition have come into scope. This is a difficult condition to document to the user and enforce in the compiler. Various proposals around this issue have been discussed, including the simple answer of disallowing continue with the repeat ... until style of loop. So far, none have had a sufficiently compelling use case to get them included in the language.

The work around is generally to invert the condition that would cause a continue to be executed, and collect the rest of the loop body under that condition. So, the following loop

-- not valid Lua 5.1 (or 5.2)
for k,v in pairs(t) do
  if isstring(k) then continue end
  -- do something to t[k] when k is not a string
end

could be written

-- valid Lua 5.1 (or 5.2)
for k,v in pairs(t) do
  if not isstring(k) then 
    -- do something to t[k] when k is not a string
  end
end

It is clear enough, and usually not a burden unless you have a series of elaborate culls that control the loop operation.

mysql_ functions have been removed from PHP 7. You can now use MySQLi or PDO.

MySQLi example:

mysqli_connect($mysql_hostname, $mysql_username, $mysql_password, $mysql_dbname);

In a nutshell, Forking is perhaps the same as "cloning under your GitHub ID/profile". A fork is anytime better than a clone, with a few exceptions, obviously. The forked repository is always being monitored/compared with the original repository unlike a cloned repository. That enables you to track the changes, initiate pull requests and also manually sync the changes made in the original repository with your forked one.

Normally you should add:

Options +ExecCGI
 AddType application/x-httpd-php .php .html
 AddHandler x-httpd-php5 .php .html

However for GoDaddy shared hosting (php-cgi), you need to add also these lines:

AddHandler fcgid-script .html
FCGIWrapper /usr/local/cpanel/cgi-sys/php5 .html

You can use the to_pydatetime method to be more explicit:

In [11]: ts = pd.Timestamp('2014-01-23 00:00:00', tz=None)

In [12]: ts.to_pydatetime()
Out[12]: datetime.datetime(2014, 1, 23, 0, 0)

It's also available on a DatetimeIndex:

In [13]: rng = pd.date_range('1/10/2011', periods=3, freq='D')

In [14]: rng.to_pydatetime()
Out[14]:
array([datetime.datetime(2011, 1, 10, 0, 0),
       datetime.datetime(2011, 1, 11, 0, 0),
       datetime.datetime(2011, 1, 12, 0, 0)], dtype=object)

here is the string you can use with -w, contains all options that curl -w supports.

{"contentType":"%{content_type}","filenameEffective":"%{filename_effective}","ftpEntryPath":"%{ftp_entry_path}","httpCode":"%{http_code}","httpConnect":"%{http_connect}","httpVersion":"%{http_version}","localIp":"%{local_ip}","localPort":"%{local_port}","numConnects":"%{num_connects}","numRedirects":"%{num_redirects}","proxySslVerifyResult":"%{proxy_ssl_verify_result}","redirectUrl":"%{redirect_url}","remoteIp":"%{remote_ip}","remotePort":"%{remote_port}","scheme":"%{scheme}","size":{"download":"%{size_download}","header":"%{size_header}","request":"%{size_request}","upload":"%{size_upload}"},"speed":{"download":"%{speed_download}","upload":"%{speed_upload}"},"sslVerifyResult":"%{ssl_verify_result}","time":{"appconnect":"%{time_appconnect}","connect":"%{time_connect}","namelookup":"%{time_namelookup}","pretransfer":"%{time_pretransfer}","redirect":"%{time_redirect}","starttransfer":"%{time_starttransfer}","total":"%{time_total}"},"urlEffective":"%{url_effective}"}

outputs JSON.

Further to Stephen Weinberg's answer, I have since implemented a handy tool called iojson, which helps to populate data to an existing object easily as well as encoding the existing object to a JSON string. A iojson middleware is also provided to work with other middlewares. More examples can be found at https://github.com/junhsieh/iojson

Example:

func main() {
    jsonStr := `{"Status":true,"ErrArr":[],"ObjArr":[{"Name":"My luxury car","ItemArr":[{"Name":"Bag"},{"Name":"Pen"}]}],"ObjMap":{}}`

    car := NewCar()

    i := iojson.NewIOJSON()

    if err := i.Decode(strings.NewReader(jsonStr)); err != nil {
        fmt.Printf("err: %s\n", err.Error())
    }

    // populating data to a live car object.
    if v, err := i.GetObjFromArr(0, car); err != nil {
        fmt.Printf("err: %s\n", err.Error())
    } else {
        fmt.Printf("car (original): %s\n", car.GetName())
        fmt.Printf("car (returned): %s\n", v.(*Car).GetName())

        for k, item := range car.ItemArr {
            fmt.Printf("ItemArr[%d] of car (original): %s\n", k, item.GetName())
        }

        for k, item := range v.(*Car).ItemArr {
            fmt.Printf("ItemArr[%d] of car (returned): %s\n", k, item.GetName())
        }
    }
}

Sample output:

car (original): My luxury car
car (returned): My luxury car
ItemArr[0] of car (original): Bag
ItemArr[1] of car (original): Pen
ItemArr[0] of car (returned): Bag
ItemArr[1] of car (returned): Pen

Try to use a

• $(window).load event

or

• $(document).ready

  because the initial values may be inconstant because of changes that occur during the parsing or during the DOM load.

This worked for me:

using System.ComponentModel.DataAnnotations;

[Key]
public int ID { get; set; }

Included page:

<!-- opening and closing tags of included page -->
<ui:composition ...>
</ui:composition>

Including page:

<!--the inclusion line in the including page with the content-->
<ui:include src="yourFile.xhtml"/>

• You start your included xhtml file with ui:composition as shown above.
• You include that file with ui:include in the including xhtml file as also shown above.

the best way is -
1) Sort the both array which are used in first and second loop.
2) if item matched then break the inner loop and hold the index value.
3) when start next iteration start inner loop with hold index value.

Each instantiation and full specialization of std::atomic<> represents a type that different threads can simultaneously operate on (their instances), without raising undefined behavior:

Objects of atomic types are the only C++ objects that are free from data races; that is, if one thread writes to an atomic object while another thread reads from it, the behavior is well-defined.

In addition, accesses to atomic objects may establish inter-thread synchronization and order non-atomic memory accesses as specified by std::memory_order.

std::atomic<> wraps operations that, in pre-C++ 11 times, had to be performed using (for example) interlocked functions with MSVC or atomic bultins in case of GCC.

Also, std::atomic<> gives you more control by allowing various memory orders that specify synchronization and ordering constraints. If you want to read more about C++ 11 atomics and memory model, these links may be useful:

• C++ atomics and memory ordering
• Comparison: Lockless programming with atomics in C++ 11 vs. mutex and RW-locks
• C++11 introduced a standardized memory model. What does it mean? And how is it going to affect C++ programming?
• Concurrency in C++11

Note that, for typical use cases, you would probably use overloaded arithmetic operators or another set of them:

std::atomic<long> value(0);
value++; //This is an atomic op
value += 5; //And so is this

Because operator syntax does not allow you to specify the memory order, these operations will be performed with std::memory_order_seq_cst, as this is the default order for all atomic operations in C++ 11. It guarantees sequential consistency (total global ordering) between all atomic operations.

In some cases, however, this may not be required (and nothing comes for free), so you may want to use more explicit form:

std::atomic<long> value {0};
value.fetch_add(1, std::memory_order_relaxed); // Atomic, but there are no synchronization or ordering constraints
value.fetch_add(5, std::memory_order_release); // Atomic, performs 'release' operation

Now, your example:

a = a + 12;

will not evaluate to a single atomic op: it will result in a.load() (which is atomic itself), then addition between this value and 12 and a.store() (also atomic) of final result. As I noted earlier, std::memory_order_seq_cst will be used here.

However, if you write a += 12, it will be an atomic operation (as I noted before) and is roughly equivalent to a.fetch_add(12, std::memory_order_seq_cst).

As for your comment:

A regular int has atomic loads and stores. Whats the point of wrapping it with atomic<>?

Your statement is only true for architectures that provide such guarantee of atomicity for stores and/or loads. There are architectures that do not do this. Also, it is usually required that operations must be performed on word-/dword-aligned address to be atomic std::atomic<> is something that is guaranteed to be atomic on every platform, without additional requirements. Moreover, it allows you to write code like this:

void* sharedData = nullptr;
std::atomic<int> ready_flag = 0;

// Thread 1
void produce()
{
    sharedData = generateData();
    ready_flag.store(1, std::memory_order_release);
}

// Thread 2
void consume()
{
    while (ready_flag.load(std::memory_order_acquire) == 0)
    {
        std::this_thread::yield();
    }

    assert(sharedData != nullptr); // will never trigger
    processData(sharedData);
}

Note that assertion condition will always be true (and thus, will never trigger), so you can always be sure that data is ready after while loop exits. That is because:

• store() to the flag is performed after sharedData is set (we assume that generateData() always returns something useful, in particular, never returns NULL) and uses std::memory_order_release order:

memory_order_release

A store operation with this memory order performs the release operation: no reads or writes in the current thread can be reordered after this store. All writes in the current thread are visible in other threads that acquire the same atomic variable

• sharedData is used after while loop exits, and thus after load() from flag will return a non-zero value. load() uses std::memory_order_acquire order:

std::memory_order_acquire

A load operation with this memory order performs the acquire operation on the affected memory location: no reads or writes in the current thread can be reordered before this load. All writes in other threads that release the same atomic variable are visible in the current thread.

This gives you precise control over the synchronization and allows you to explicitly specify how your code may/may not/will/will not behave. This would not be possible if only guarantee was the atomicity itself. Especially when it comes to very interesting sync models like the release-consume ordering.

As i've stated the back button is for every one of us a pain in some place... that said...

As long as you load the page normally it makes a lot of trouble... for a standard "site" it will not change that much... however i think you can make something like this

The user access everytime to your page .php that choose what to load. You can try to work a little with cache (to not cache page) and maybe expire date.

But the long term solution will be put a code on "onload" event to fetch the data trought Ajax, this way you can (with Javascript) run the code you want, and example refresh the page.

If your Main class is in a package called FileManagement, then try:

java -cp . FileManagement.Main

in the parent folder of the FileManagement folder.

If your Main class is not in a package (the default package) then cd to the FileManagement folder and try:

java -cp . Main

Visit https://developers.facebook.com/apps/ and select your application.

Go to Settings -> Basic. Add a Contact Email and a Privacy Policy URL. The Privacy Policy URL should be a webpage where you have hosted the terms and conditions of your application and data used.

Toggle the button in the top of the screen, as seen below, in order to switch from Development to Live.

 
INSERT INTO table_name1

SELECT id, name, address, contact_number FROM table_name2;   

Since you have jQuery on the page, you can remove that onclick attribute and the majorpointsexpand function. Add the following script to the bottom of you page or, preferably, to an external .js file:

$(function(){

  $('.majorpointslegend').click(function(){
    $(this).next().toggle().text( $(this).is(':visible')?'Collapse':'Expand' );
  });

});

This solutionshould work with your HTML as is but it isn't really a very robust answer. If you change your fieldset layout, it could break it. I'd suggest that you put a class attribute in that hidden div, like class="majorpointsdetail" and use this code instead:

$(function(){

  $('.majorpoints').on('click', '.majorpointslegend', function(event){
    $(event.currentTarget).find('.majorpointsdetail').toggle();
    $(this).text( $(this).is(':visible')?'Collapse':'Expand' );
  });

});

Obs: there's no closing </fieldset> tag in your question so I'm assuming the hidden div is inside the fieldset.

The accepted answer is great. This is not answer, but just an illustration of the issue.

I present a viewController like this:

inside vc1:

func showVC2() {
    if let navController = self.navigationController{
        navController.present(vc2, animated: true)
    }
}

inside vc2:

func returnFromVC2() {
    if let navController = self.navigationController {
        navController.popViewController(animated: true)
    }else{
        print("navigationController is nil") <-- I was reaching here!
    }
}

As 'stefandouganhyde' has said: "it is not contained by your UINavigationController or any other"

new solution:

func returnFromVC2() {
    dismiss(animated: true, completion: nil)
}

This can also come up when running unit tests if you are testing a component with custom elements. In that case custom_elements_schema needs to be added to the testingModule that gets setup at the beginning of the .spec.ts file for that component. Here is an example of how the header.component.spec.ts setup would begin:

import { CUSTOM_ELEMENTS_SCHEMA } from '@angular/core';

describe('HeaderComponent', () => {
  let component: HeaderComponent;
  let fixture: ComponentFixture<HeaderComponent>;

  beforeEach(async(() => {
    TestBed.configureTestingModule({
      declarations: [PrizeAddComponent],
      schemas: [
        CUSTOM_ELEMENTS_SCHEMA
      ],
    })
      .compileComponents();
  }));

Suppose

a = ['a', 'b', 'c', 3, 4, 'd', 6, 7, 8]

and the list of indexes is stored in

b= [0, 1, 2, 4, 6, 7, 8]

then a simple one-line solution will be

c = [a[i] for i in b]

Create an abstract method, and have each of your enumeration values override it. Since you know the opposite while you're creating it, there's no need to dynamically generate or create it.

It doesn't read nicely though; perhaps a switch would be more manageable?

public enum Direction {
    NORTH(1) {
        @Override
        public Direction getOppositeDirection() {
            return Direction.SOUTH;
        }
    },
    SOUTH(-1) {
        @Override
        public Direction getOppositeDirection() {
            return Direction.NORTH;
        }
    },
    EAST(-2) {
        @Override
        public Direction getOppositeDirection() {
            return Direction.WEST;
        }
    },
    WEST(2) {
        @Override
        public Direction getOppositeDirection() {
            return Direction.EAST;
        }
    };

    Direction(int code){
        this.code=code;
    }
    protected int code;

    public int getCode() {
        return this.code;
    }

    public abstract Direction getOppositeDirection();
}

Another option is:

when:

def response = mockMvc.perform(
            get('/path/to/api')
            .header("Content-Type", "application/json"))

then:

response.andExpect(status().isOk())
response.andReturn().getResponse().getContentAsString() == "what you expect"

Yes, cd; and cd - would work. The reason It can see is that, directory is being deleted from any other terminal or any other program and recreate it. So i-node entry is modified so program can not access old i-node entry.

There is no single simple way to do it, because PostgreSQL might be installed and set up in many different ways:

• Installed from source in a user home directory
• Installed from source into /opt or /usr/local, manually started or started by an init script
• Installed from distributor rpm / deb packages and started via init script
• Installed from 3rd party rpm / deb packages and started via init script
• Installed from packages but not set to start
• Client installed, connecting to a server on a different computer
• Installed and running but not on the default PATH or default port

You can't rely on psql being on the PATH. You can't rely on there being only one psql on the system (multiple versions might be installed in different ways). You can't do it based on port, as there's no guarantee it's on port 5432, or that there aren't multiple versions.

Prompt the user and ask them.

Unfortunately, setTimeout() is the only reliable way (not the only way, but the only reliable way) to pause the execution of the script without blocking the UI.

It's not that hard to use actually, instead of writing this:

var x = 1;

// Place mysterious code that blocks the thread for 100 ms.

x = x * 3 + 2;
var y = x / 2;

you use setTimeout() to rewrite it this way:

var x = 1;
var y = null; // To keep under proper scope

setTimeout(function() {
    x = x * 3 + 2;
    y = x / 2;
}, 100);

I understand that using setTimeout() involves more thought than a desirable sleep() function, but unfortunately the later doesn't exist. Many workarounds are there to try to implement such functions. Some using busy loops:

function sleep(milliseconds) {
  var start = new Date().getTime();
  for (var i = 0; i < 1e7; i++) {
    if ((new Date().getTime() - start) > milliseconds){
      break;
    }
  }
}

others using an XMLHttpRequest tied with a server script that sleeps for a amount of time before returning a result.

Unfortunately, those are workarounds and are likely to cause other problems (such as freezing browsers). It is recommended to simply stick with the recommended way, which is setTimeout()).

Yup, As @luizfelippe mentioned Session class has been removed since SDK 4.0. We need to use LoginManager.

I just looked into LoginButton class for logout. They are making this kind of check. They logs out only if accessToken is not null. So, I think its better to have this in our code too..

AccessToken accessToken = AccessToken.getCurrentAccessToken();
if(accessToken != null){
    LoginManager.getInstance().logOut();
}

do this 2 steps: 1. in this menu: project -> yourproject properties... -> Build : uncheck "prefer 32-Bit" 2. in connectionString : write cuotes before and after Extended properties, like this: Extended Properties='Excel 12.0 Xml;HDR=YES'

                var fileName = string.Format("{0}", openFileDialog1.FileName);
            //var connectionString = string.Format("Provider=Microsoft.Jet.OLEDB.4.0; data source={0}; Extended Properties=Excel 8.0;", fileName);
            var connectionString = string.Format("Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0}; Extended Properties='Excel 12.0 Xml;HDR=YES'", fileName);
            var adapter = new OleDbDataAdapter("SELECT * FROM [Sheet1$]", connectionString);
            var ds = new DataSet();

            adapter.Fill(ds, TableNmae);

            DataTable data = ds.Tables[TableNmae];
            dg1.DataSource = data;

When you say:

 #include <cstring>

the g++ compiler should put the <string.h> declarations it itself includes into the std:: AND the global namespaces. It looks for some reason as if it is not doing that. Try replacing one instance of strcpy with std::strcpy and see if that fixes the problem.

The difference is that miniconda is just shipping the repository management system. So when you install it there is just the management system without packages. Whereas with Anaconda, it is like a distribution with some built in packages.

Like with any Linux distribution, there are some releases which bundles lots of updates for the included packages. That is why there is a difference in version numbering. If you only decide to upgrade Anaconda, you are updating a whole system.

max is a builtin function in python, which is used to get max value from a sequence, i.e (list, tuple, set, etc..)

print(max([9, 7, 12, 5]))

# prints 12 

I tried this solution with Microsoft.SqlServer.Management but it didn't work well with .NET 4.0 so I wrote another solution using .NET libs framework only.

string script = File.ReadAllText(@"E:\someSqlScript.sql");

// split script on GO command
IEnumerable<string> commandStrings = Regex.Split(script, @"^\s*GO\s*$", RegexOptions.Multiline | RegexOptions.IgnoreCase);

Connection.Open();
foreach (string commandString in commandStrings)
{
    if (!string.IsNullOrWhiteSpace(commandString.Trim()))
    {
        using(var command = new SqlCommand(commandString, Connection))
        {
            command.ExecuteNonQuery();
        }
    }
}     
Connection.Close();

You need to prevent the default behaviour. You can either use e.preventDefault() or return false; In this case, the best thing is, you can use return false; here:

If your are using MySQL Latest version following may help to reach your requirement.

select * from products where attribs_json->"$.feature.value[*]" in (1,3)

Basically, you check if an object is an instance of a specific class. You normally use it, when you have a reference or parameter to an object that is of a super class or interface type and need to know whether the actual object has some other type (normally more concrete).

Example:

public void doSomething(Number param) {
  if( param instanceof Double) {
    System.out.println("param is a Double");
  }
  else if( param instanceof Integer) {
    System.out.println("param is an Integer");
  }

  if( param instanceof Comparable) {
    //subclasses of Number like Double etc. implement Comparable
    //other subclasses might not -> you could pass Number instances that don't implement that interface
    System.out.println("param is comparable"); 
  }
}

Note that if you have to use that operator very often it is generally a hint that your design has some flaws. So in a well designed application you should have to use that operator as little as possible (of course there are exceptions to that general rule).

I know that I came too late but I would like to offer some alternatives, not something extraordinary but some cases that none mentioned here. In case that someone doesn't care so much for efficiency but he wants something with more simplicity(perhaps find the last entry value with one line of code), all this will get quite simplified with the arrival of Java 8 . I provide some useful scenarios.

For the sake of the completeness, I compare these alternatives with the solution of arrays that already mentioned in this post by others users. I sum up all the cases and i think they would be useful(when performance does matter or no) especially for new developers, always depends on the matter of each problem

Possible Alternatives

Usage of Array Method

I took it from the previous answer to to make the follow comparisons. This solution belongs @feresr.

  public static String FindLasstEntryWithArrayMethod() {
        return String.valueOf(linkedmap.entrySet().toArray()[linkedmap.size() - 1]);
    }

Usage of ArrayList Method

Similar to the first solution with a little bit different performance

public static String FindLasstEntryWithArrayListMethod() {
        List<Entry<Integer, String>> entryList = new ArrayList<Map.Entry<Integer, String>>(linkedmap.entrySet());
        return entryList.get(entryList.size() - 1).getValue();
    }

Reduce Method

This method will reduce the set of elements until getting the last element of stream. In addition, it will return only deterministic results

public static String FindLasstEntryWithReduceMethod() {
        return linkedmap.entrySet().stream().reduce((first, second) -> second).orElse(null).getValue();
    }

SkipFunction Method

This method will get the last element of the stream by simply skipping all the elements before it

public static String FindLasstEntryWithSkipFunctionMethod() {
        final long count = linkedmap.entrySet().stream().count();
        return linkedmap.entrySet().stream().skip(count - 1).findFirst().get().getValue();
    }

Iterable Alternative

Iterables.getLast from Google Guava. It has some optimization for Lists and SortedSets too

public static String FindLasstEntryWithGuavaIterable() {
        return Iterables.getLast(linkedmap.entrySet()).getValue();
    }

Here is the full source code

import com.google.common.collect.Iterables;
import java.math.BigDecimal;
import java.math.RoundingMode;
import java.util.ArrayList;
import java.util.LinkedHashMap;
import java.util.List;

import java.util.Map.Entry;

public class PerformanceTest {

    private static long startTime;
    private static long endTime;
    private static LinkedHashMap<Integer, String> linkedmap;

    public static void main(String[] args) {
        linkedmap = new LinkedHashMap<Integer, String>();

        linkedmap.put(12, "Chaitanya");
        linkedmap.put(2, "Rahul");
        linkedmap.put(7, "Singh");
        linkedmap.put(49, "Ajeet");
        linkedmap.put(76, "Anuj");

        //call a useless action  so that the caching occurs before the jobs starts.
        linkedmap.entrySet().forEach(x -> {});



        startTime = System.nanoTime();
        FindLasstEntryWithArrayListMethod();
        endTime = System.nanoTime();
        System.out.println("FindLasstEntryWithArrayListMethod : " + "took " + new BigDecimal((endTime - startTime) / 1000000.000).setScale(3, RoundingMode.CEILING) + " milliseconds");


         startTime = System.nanoTime();
        FindLasstEntryWithArrayMethod();
        endTime = System.nanoTime();
        System.out.println("FindLasstEntryWithArrayMethod : " + "took " + new BigDecimal((endTime - startTime) / 1000000.000).setScale(3, RoundingMode.CEILING) + " milliseconds");

        startTime = System.nanoTime();
        FindLasstEntryWithReduceMethod();
        endTime = System.nanoTime();

        System.out.println("FindLasstEntryWithReduceMethod : " + "took " + new BigDecimal((endTime - startTime) / 1000000.000).setScale(3, RoundingMode.CEILING) + " milliseconds");

        startTime = System.nanoTime();
        FindLasstEntryWithSkipFunctionMethod();
        endTime = System.nanoTime();

        System.out.println("FindLasstEntryWithSkipFunctionMethod : " + "took " + new BigDecimal((endTime - startTime) / 1000000.000).setScale(3, RoundingMode.CEILING) + " milliseconds");

        startTime = System.currentTimeMillis();
        FindLasstEntryWithGuavaIterable();
        endTime = System.currentTimeMillis();
        System.out.println("FindLasstEntryWithGuavaIterable : " + "took " + (endTime - startTime) + " milliseconds");


    }

    public static String FindLasstEntryWithReduceMethod() {
        return linkedmap.entrySet().stream().reduce((first, second) -> second).orElse(null).getValue();
    }

    public static String FindLasstEntryWithSkipFunctionMethod() {
        final long count = linkedmap.entrySet().stream().count();
        return linkedmap.entrySet().stream().skip(count - 1).findFirst().get().getValue();
    }

    public static String FindLasstEntryWithGuavaIterable() {
        return Iterables.getLast(linkedmap.entrySet()).getValue();
    }

    public static String FindLasstEntryWithArrayListMethod() {
        List<Entry<Integer, String>> entryList = new ArrayList<Map.Entry<Integer, String>>(linkedmap.entrySet());
        return entryList.get(entryList.size() - 1).getValue();
    }

    public static String FindLasstEntryWithArrayMethod() {
        return String.valueOf(linkedmap.entrySet().toArray()[linkedmap.size() - 1]);
    }
}

Here is the output with performance of each method

FindLasstEntryWithArrayListMethod : took 0.162 milliseconds
FindLasstEntryWithArrayMethod : took 0.025 milliseconds
FindLasstEntryWithReduceMethod : took 2.776 milliseconds
FindLasstEntryWithSkipFunctionMethod : took 3.396 milliseconds
FindLasstEntryWithGuavaIterable : took 11 milliseconds

The meaning of CascadeType.ALL is that the persistence will propagate (cascade) all EntityManager operations (PERSIST, REMOVE, REFRESH, MERGE, DETACH) to the relating entities.

It seems in your case to be a bad idea, as removing an Address would lead to removing the related User. As a user can have multiple addresses, the other addresses would become orphans. However the inverse case (annotating the User) would make sense - if an address belongs to a single user only, it is safe to propagate the removal of all addresses belonging to a user if this user is deleted.

BTW: you may want to add a mappedBy="addressOwner" attribute to your User to signal to the persistence provider that the join column should be in the ADDRESS table.

This will fail though if the string can contain strings like "miscontrue".

   Regex.Matches("7,true,NA,false:67,false,NA,false:5,false,NA,false:5,false,NA,false", "true").Count;

To add to what joshb has stated already - this works just fine for me. Make sure to add references to Microsoft.Expression.Interactions.dll and System.Windows.Interactivity.dll and in your xaml do:

    xmlns:i="http://schemas.microsoft.com/expression/2010/interactivity"

I ended up using something like this for my needs. This shows that you can also pass a custom parameter:

<i:Interaction.Triggers>
            <i:EventTrigger EventName="SelectionChanged">

                <i:InvokeCommandAction Command="{Binding Path=DataContext.RowSelectedItem, RelativeSource={RelativeSource AncestorType={x:Type Window}}}" 
                                       CommandParameter="{Binding Path=SelectedItem, RelativeSource={RelativeSource Mode=FindAncestor, AncestorType=DataGrid}}" />
            </i:EventTrigger>
</i:Interaction.Triggers>

res.send() will send the HTTP response. Its syntax is,

res.send([body])

The body parameter can be a Buffer object, a String, an object, or an Array. For example:

res.send(new Buffer('whoop'));
res.send({ some: 'json' });
res.send('<p>some html</p>');
res.status(404).send('Sorry, we cannot find that!');
res.status(500).send({ error: 'something blew up' });

See this for more info.

res.end() will end the response process. This method actually comes from Node core, specifically the response.end() method of http.ServerResponse. It is used to quickly end the response without any data. For example:

res.end();
res.status(404).end();

Then there is an option that says logging floating window, you just need to disable that and you will get rid of this infernal bubble for good

I've found lots of posts across the web on the various ways to do the request, but none that actually show how to process the response synchronously on AWS Lambda.

Here's a Node 6.10.3 lambda function that uses an https request, collects and returns the full body of the response, and passes control to an unlisted function processBody with the results. I believe http and https are interchangable in this code.

I'm using the async utility module, which is easier to understand for newbies. You'll need to push that to your AWS Stack to use it (I recommend the serverless framework).

Note that the data comes back in chunks, which are gathered in a global variable, and finally the callback is called when the data has ended.

'use strict';

const async = require('async');
const https = require('https');

module.exports.handler = function (event, context, callback) {

    let body = "";
    let countChunks = 0;

    async.waterfall([
        requestDataFromFeed,
        // processBody,
    ], (err, result) => {
        if (err) {
            console.log(err);
            callback(err);
        }
        else {
            const message = "Success";
            console.log(result.body);
            callback(null, message);
        }
    });

    function requestDataFromFeed(callback) {
        const url = 'https://put-your-feed-here.com';
        console.log(`Sending GET request to ${url}`);
        https.get(url, (response) => {
            console.log('statusCode:', response.statusCode);
            response.on('data', (chunk) => {
                countChunks++;
                body += chunk;
            });
            response.on('end', () => {
                const result = {
                    countChunks: countChunks,
                    body: body
                };
                callback(null, result);
            });
        }).on('error', (err) => {
            console.log(err);
            callback(err);
        });
    }
};

Please keep your

<form method="POST" action="XYZ">

@RequestMapping(value="/XYZ", method=RequestMethod.POST)
    public void handleSave(@RequestParam String action){

Your form action attribute value must match to value of @RequestMapping, So that Spring MVC can resolve it.

Also, as you told it is giving 404 after changing, for this, can you please check whether control is entering inside handleSave() method.

I think, as you are not returning any thing from handleSave() method, you have to look at it.

if it still not work, can you please post your spring logs.

Also, make sure that your request should come like

/PORTAL/save

if there is anything between like PORTAL/jsp/save the mention in @RequestMapping(value="/jsp/save")

I also suggest using contourf(Z). For my problem, I wanted to visualize a 3D histogram in 2D, but the contours were too smooth to represent a top view of histogram bars.

So in my case, I prefer to use jucestain's answer. The default shading faceted of pcolor() is more suitable. However, pcolor() does not use the last row and column of the plotted matrix. For this, I used the padarray() function:

pcolor(padarray(Z,[1 1],0,'post'))

Sorry if that is not really related to the original post

Yes it is! Just add them to your database-folder ( depending on the OS ) and run a command such as "MySQL Fix Permissions". This re-stored the database. See too it that the correct permissions are set on the files aswell.

Here is another way that I came up with: Let's say you want to get a float between 5.5 and 7, with 3 decimals.

float myFloat;
int myInt;
System.Random rnd = new System.Random();

void GenerateFloat()
{
myInt = rnd.Next(1, 2000);
myFloat = (myInt / 1000) + 5.5f;
}

That way you will always get a bigger number than 5.5 and a smaller number than 7.

dom event delegation is something different from the computer science definition.

It refers to handling bubbling events from many elements, like table cells, from a parent object, like the table. It can keep the code simpler, especially when adding or removing elements, and saves some memory.

Try it:

document.referrer

When you change you are in a iframe your host is "referrer".

could it be that you forgot to load it in the document ready function?

$(document).ready(function () {

    //your jQuery function
});

Another veneration of find_elements_by_xpath(".//*") is:

find_elements(By.XPATH, ".//*")

I think using md5 or sha256 or any hash optimized for speed is perfectly fine and am very curious to hear any rebuttle other users might have. Here are my reasons

1. If you allow users to use weak passwords such as God, love, war, peace then no matter the encryption you will still be allowing the user to type in the password not the hash and these passwords are often used first, thus this is NOT going to have anything to do with encryption.

2. If your not using SSL or do not have a certificate then attackers listening to the traffic will be able to pull the password and any attempts at encrypting with javascript or the like is client side and easily cracked and overcome. Again this is NOT going to have anything to do with data encryption on server side.

3. Brute force attacks will take advantage weak passwords and again because you allow the user to enter the data if you do not have the login limitation of 3 or even a little more then the problem will again NOT have anything to do with data encryption.

4. If your database becomes compromised then most likely everything has been compromised including your hashing techniques no matter how cryptic you've made it. Again this could be a disgruntled employee XSS attack or sql injection or some other attack that has nothing to do with your password encryption.

I do believe you should still encrypt but the only thing I can see the encryption does is prevent people that already have or somehow gained access to the database from just reading out loud the password. If it is someone unauthorized to on the database then you have bigger issues to worry about that's why Sony got took because they thought an encrypted password protected everything including credit card numbers all it does is protect that one field that's it.

The only pure benefit I can see to complex encryptions of passwords in a database is to delay employees or other people that have access to the database from just reading out the passwords. So if it's a small project or something I wouldn't worry to much about security on the server side instead I would worry more about securing anything a client might send to the server such as sql injection, XSS attacks or the plethora of other ways you could be compromised. If someone disagrees I look forward to reading a way that a super encrypted password is a must from the client side.

The reason I wanted to try and make this clear is because too often people believe an encrypted password means they don't have to worry about it being compromised and they quit worrying about securing the website.

The answer given above can't solve my problem.So I change async into false to get the alert message.

jQuery.ajax({
            type:"post",
            dataType:"json",
            async: false,
            url: myAjax.ajaxurl,
            data: {action: 'submit_data', info: info},
            success: function(data) {
                alert("Data was succesfully captured");
            },
        });

Being a little smarter:

function strand($length){
  if($length > 0)
    return chr(rand(33, 126)) . strand($length - 1);
}

In Scala use the well known Apache Commons validators.

 def ip(ip: String) = InetAddressValidator.getInstance().isValid(ip)

Following the test's of the method ip(ip: String):

First, remove all the containers using the following command

sudo docker ps -a -q | xargs -n 1 -I {} sudo docker rm {}

Then, remove the image by its ID using the following command

sudo docker rmi <image-id>

getdate() 

is the direct equivalent, but you should always use UTC datetimes

getutcdate()

whether your app operates across timezones or not - otherwise you run the risk of screwing up date math at the spring/fall transitions

Choose the build

The answer is that you Mouse over the icon for your build and at the end of the line you'll see a little colored minus in a circle. This removes the build and you can now click on the + sign and choose a new build for submitting.

It is an unbelievably complicated web page with tricks and gizmos to do the thing you want. I'm sure Steve never saw this page or tried to use it.

Surely it's better practice to design the screen so that you can see the options all the time, not to have the screen change depending on whether you have an app in review or not!

I had this problem because the page I called ajax post from had EnableViewState="false" and EnableViewStateMac="false" but not the page called.

When I put this on both pages everything started to work. I suspected this when I saw MAC address exception.

In your case, you want to check for 'nt' as os.name output:

import os

if os.name == 'nt':
     ...

There is also a note on os.name:

See also sys.platform has a finer granularity. os.uname() gives system-dependent version information.

The platform module provides detailed checks for the system’s identity.

When we make a dump file with mysqldump, what it contains is a big SQL script for recreating the databse contents. So we restore it by using starting up MySQL’s command-line client:

mysql -uroot -p 

(where root is our admin user name for MySQL), and once connected to the database we need commands to create the database and read the file in to it:

create database new_db;
use new_db;
\. dumpfile.sql

Details will vary according to which options were used when creating the dump file.

Again I suggest Simple and Easy

Its Working Perfect with ajax when user search and select it saves the selected information via ajax

 $("#vendor-brands").select2({
   ajax: {
   url:site_url('general/get_brand_ajax_json'),
  dataType: 'json',
  delay: 250,
  data: function (params) {
  return {
    q: params.term, // search term
    page: params.page
  };
},
processResults: function (data, params) {
  // parse the results into the format expected by Select2
  // since we are using custom formatting functions we do not need to
  // alter the remote JSON data, except to indicate that infinite
  // scrolling can be used
  params.page = params.page || 1;

  return {
    results: data,
    pagination: {
      more: (params.page * 30) < data.total_count
    }
  };
},
cache: true
},
escapeMarkup: function (markup) { return markup; }, // let our custom    formatter work
minimumInputLength: 1,
}).on("change", function(e) {


  var lastValue = $("#vendor-brands option:last-child").val();
  var lastText = $("#vendor-brands option:last-child").text();

  alert(lastValue+' '+lastText);
 });

Multiplatform, stable, best solution:

use fkill to kill process which is taking your port:

fkill -f :8080

To install fkill use command: npm i -g fkill

A poor man's option is to use the tool tig¹ on HEAD, search for the commit, and then visually follow the line from that commit back up until a merge commit is seen. The default merge message should specify what branch is getting merged to where :)

¹ Tig is an ncurses-based text-mode interface for Git. It functions mainly as a Git repository browser, but it can also assist in staging changes for commit at chunk level and act as a pager for output from various Git commands.

Calling .isoformat() on a date object will give you YYYY-MM-DD

from datetime import date, timedelta
(date.today() - timedelta(1)).isoformat()

select * from all_constraints
where owner = '<NAME>'
and constraint_name = 'SYS_C00381400'
/

Like all data dictionary views, this a USER_CONSTRAINTS view if you just want to check your current schema and a DBA_CONSTRAINTS view for administration users.

The construction of the constraint name indicates a system generated constraint name. For instance, if we specify NOT NULL in a table declaration. Or indeed a primary or unique key. For example:

SQL> create table t23 (id number not null primary key)
  2  /

Table created.

SQL> select constraint_name, constraint_type
  2  from user_constraints
  3  where table_name = 'T23'
  4  /

CONSTRAINT_NAME                C
------------------------------ -
SYS_C00935190                  C
SYS_C00935191                  P

SQL>

'C' for check, 'P' for primary.

Generally it's a good idea to give relational constraints an explicit name. For instance, if the database creates an index for the primary key (which it will do if that column is not already indexed) it will use the constraint name oo name the index. You don't want a database full of indexes named like SYS_C00935191.

To be honest most people don't bother naming NOT NULL constraints.

This solve my problème:

$description = strip_tags($value['Description']);
$description=preg_replace('/&(?!#?[a-z0-9]+;)/', '&', $description);
$description= preg_replace("/(^[\r\n]*|[\r\n]+)[\s\t]*[\r\n]+/", "\n", $description);
$description=str_replace(' & ', ' & ', html_entity_decode((htmlspecialchars_decode($description))));

Combine @vincsilver and @jdigital's answers with some modifications,

1. export .reg to current directory
2. add date mark

code:

set TODAY=%DATE:~0,4%-%DATE:~5,2%-%DATE:~8,2%

regedit /e "%CD%\user_env_variables[%TODAY%].reg" "HKEY_CURRENT_USER\Environment"
regedit /e "%CD%\global_env_variables[%TODAY%].reg" "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Session Manager\Environment"

Output would like:

global_env_variables[2017-02-14].reg
user_env_variables[2017-02-14].reg

A dictionary is not indexed, but it is in some way, ordered. The following would give you the first existing key:

list(my_dict.keys())[0]

Your routing needs to be set up along the lines of {controller}/{action}/{firstItem}. If you left the routing as the default {controller}/{action}/{id} in your global.asax.cs file, then you will need to pass in id.

routes.MapRoute(
    "Inventory",
    "Inventory/{action}/{firstItem}",
    new { controller = "Inventory", action = "ListAll", firstItem = "" }
);

... or something close to that.

Try setting your ScriptManager to this.

<asp:ScriptManager ID="ScriptManager1" runat="server" EnablePartialRendering="true" /> 

Cause

Conda and pip install scikit-learn under ~/anaconda3/envs/$ENV/lib/python3.7/site-packages, however Jupyter notebook looks for the package under ~/anaconda3/lib/python3.7/site-packages.

Therefore, even when the environment is specified to conda, it does not work.

conda install -n $ENV scikit-learn # Does not work

Solution

pip 3 install the package under ~/anaconda3/lib/python3.7/site-packages.

Verify

After pip3, in a Jupyter notebook.

import sklearn
sklearn.__file__

~/anaconda3/lib/python3.7/site-packages/sklearn/init.py'

Another option is to do it via CSS ...

E.g. 1

<span style="font-weight: bold;">Hello stackoverflow!</span>

E.g. 2

<style type="text/css">
    #text
    {
        font-weight: bold;
    }
</style>

<div id="text">
    Hello again!
</div>

min and max have to loop through the input array anyway - how else would they find the biggest or smallest element?

So just a quick for..in loop will work just fine.

var min = Infinity, max = -Infinity, x;
for( x in input) {
    if( input[x] < min) min = input[x];
    if( input[x] > max) max = input[x];
}

The output of Get-Service is a System.ServiceProcess.ServiceController .NET class that can operate on remote computers. How it accomplishes that, I don't know - probably DCOM or WMI. Once you've gotten one of these from Get-Service, it can be passed into Stop-Service which most likely just calls the Stop() method on this object. That stops the service on the remote machine. In fact, you could probably do this as well:

(get-service -ComputerName remotePC -Name Spooler).Stop()

I happened to come up with a solution very similar to @Andrew, only DRY

class MetaFoo(type):

    def __new__(mc1, name, bases, nmspc):
        nmspc.update({'thingy': MetaFoo.thingy})
        return super(MetaFoo, mc1).__new__(mc1, name, bases, nmspc)

    @property
    def thingy(cls):
        if not inspect.isclass(cls):
            cls = type(cls)
        return cls._thingy

    @thingy.setter
    def thingy(cls, value):
        if not inspect.isclass(cls):
            cls = type(cls)
        cls._thingy = value

class Foo(metaclass=MetaFoo):
    _thingy = 23

class Bar(Foo)
    _thingy = 12

This has the best of all answers:

The "metaproperty" is added to the class, so that it will still be a property of the instance

1. Don't need to redefine thingy in any of the classes
2. The property works as a "class property" in for both instance and class
3. You have the flexibility to customize how _thingy is inherited

In my case, I actually customized _thingy to be different for every child, without defining it in each class (and without a default value) by:

   def __new__(mc1, name, bases, nmspc):
       nmspc.update({'thingy': MetaFoo.services, '_thingy': None})
       return super(MetaFoo, mc1).__new__(mc1, name, bases, nmspc)

I modified Brad Larson's Code. It will aspect fill the image in given rect.

-(UIImage*) scaleAndCropToSize:(CGSize)newSize;
{
    float ratio = self.size.width / self.size.height;

    UIGraphicsBeginImageContext(newSize);

    if (ratio > 1) {
        CGFloat newWidth = ratio * newSize.width;
        CGFloat newHeight = newSize.height;
        CGFloat leftMargin = (newWidth - newHeight) / 2;
        [self drawInRect:CGRectMake(-leftMargin, 0, newWidth, newHeight)];
    }
    else {
        CGFloat newWidth = newSize.width;
        CGFloat newHeight = newSize.height / ratio;
        CGFloat topMargin = (newHeight - newWidth) / 2;
        [self drawInRect:CGRectMake(0, -topMargin, newSize.width, newSize.height/ratio)];
    }

    UIImage* newImage = UIGraphicsGetImageFromCurrentImageContext();
    UIGraphicsEndImageContext();

    return newImage;
}

This type of error can also occur when the excel file is corrupted for some reason

None of these solutions worked for me inside a Weebly "add your own html" box. Not sure what they are doing with their code. But I found this solution at https://benmarshall.me/responsive-iframes/ and it works perfectly.

C:\Program Files\Android\Android Studio\jre\bin>java -version
openjdk version "1.8.0_76-release"
OpenJDK Runtime Environment (build 1.8.0_76-release-b03)
OpenJDK 64-Bit Server VM (build 25.76-b03, mixed mode)

Somehow the Studio installer would install another version under:

C:\Program Files\Android\Android Studio\jre\jre\bin>java -version
openjdk version "1.8.0_76-release"
OpenJDK Runtime Environment (build 1.8.0_76-release-b03)
OpenJDK 64-Bit Server VM (build 25.76-b03, mixed mode)

where the latest version was installed the Java DevKit installer in:

C:\Program Files\Java\jre1.8.0_121\bin>java -version
java version "1.8.0_121"
Java(TM) SE Runtime Environment (build 1.8.0_121-b13)
Java HotSpot(TM) 64-Bit Server VM (build 25.121-b13, mixed mode)

Need to clean up the Android Studio so it would use the proper latest 1.8.0 versions.

According to How to set Java SDK path in AndroidStudio? one could override with a specific JDK but when I renamed

C:\Program Files\Android\Android Studio\jre\jre\

to:

C:\Program Files\Android\Android Studio\jre\oldjre\

And restarted Android Studio, it would complain that the jre was invalid. When I tried to aecify an JDK to pick the one in C:\Program Files\Java\jre1.8.0_121\bin or:

C:\Program Files\Java\jre1.8.0_121\

It said that these folders are invalid. So I guess that the embedded version must have some special purpose.

This is the only difference:

each:

irb> [1,2,3].each { |x| }
  => [1, 2, 3]
irb> x
NameError: undefined local variable or method `x' for main:Object
    from (irb):2
    from :0

for:

irb> for x in [1,2,3]; end
  => [1, 2, 3]
irb> x
  => 3

With the for loop, the iterator variable still lives after the block is done. With the each loop, it doesn't, unless it was already defined as a local variable before the loop started.

Other than that, for is just syntax sugar for the each method.

When @collection is nil both loops throw an exception:

Exception: undefined local variable or method `@collection' for main:Object

When migrating an OpenGL app from SDK 3 to 4, layoutSubviews was not called anymore. After a lot of trial and error I finally opened MainWindow.xib, selected the Window object, in the inspector chose Window Attributes tab (leftmost) and checked "Visible at launch". It seems that in SDK 3 it still used to cause a layoutSubViews call, but not in 4.

6 hours of frustration put to an end.

If you're using executeScalar:

cmd.ExecuteScalar();
result_id=cmd.LastInsertedId.ToString();

If you use Eclipse Collections you can use the collectIf() method.

MutableList<Integer> source =
    Lists.mutable.with(1, null, 2, null, 3, null, 4, null, 5);

MutableList<String> result = source.collectIf(Objects::nonNull, String::valueOf);

Assert.assertEquals(Lists.immutable.with("1", "2", "3", "4", "5"), result);

It evaluates eagerly and should be a bit faster than using a Stream.

Note: I am a committer for Eclipse Collections.

Difference between small and little

function getPosition( el ) {
    var x = 0;
    var y = 0;
    while( el && !isNaN( el.offsetLeft ) && !isNaN( el.offsetTop ) ) {
    x += el.offsetLeft - el.scrollLeft;
    y += el.offsetTop - el.scrollTop;
    el = el.offsetParent;
    }
    return { top: y, left: x };
}

Look a example coordinates: http://javascript.info/tutorial/coordinates

Additionally to the solutions that were suggested in sibling comments, you may change your testing approach a little bit and test not the whole page all at once (with a deep children components tree), but do an isolated component testing. This will simplify testing of onClick() and similar events (see example below).

The idea is to test only one component at a time and not all of them together. In this case all children components will be mocked using the jest.mock() function.

Here is an example of how the onClick() event may be tested in an isolated SearchForm component using Jest and react-test-renderer.

import React from 'react';
import renderer from 'react-test-renderer';
import { SearchForm } from '../SearchForm';

describe('SearchForm', () => {
  it('should fire onSubmit form callback', () => {
    // Mock search form parameters.
    const searchQuery = 'kittens';
    const onSubmit = jest.fn();

    // Create test component instance.
    const testComponentInstance = renderer.create((
      <SearchForm query={searchQuery} onSearchSubmit={onSubmit} />
    )).root;

    // Try to find submit button inside the form.
    const submitButtonInstance = testComponentInstance.findByProps({
      type: 'submit',
    });
    expect(submitButtonInstance).toBeDefined();

    // Since we're not going to test the button component itself
    // we may just simulate its onClick event manually.
    const eventMock = { preventDefault: jest.fn() };
    submitButtonInstance.props.onClick(eventMock);

    expect(onSubmit).toHaveBeenCalledTimes(1);
    expect(onSubmit).toHaveBeenCalledWith(searchQuery);
  });
});

Try this:

update table YourTable
set YourField = substring(YourField, 5, len(YourField)-3);

I accidentally installed 'serial' (sudo python -m pip install serial) instead of 'pySerial' (sudo python -m pip install pyserial), which lead to the same error.

If the previously mentioned solutions did not work for you, double check if you installed the correct library.

Reverting the revert will do the trick

For example,

If abcdef is your commit and ghijkl is the commit you have when you reverted the commit abcdef, then run:

git revert ghijkl

This will revert the revert

While I do like regular expressions in general, for this kind of state-dependent tokenization I believe a simple parser (which in this case is much simpler than that word might make it sound) is probably a cleaner solution, in particular with regards to maintainability, e.g.:

String input = "foo,bar,c;qual=\"baz,blurb\",d;junk=\"quux,syzygy\"";
List<String> result = new ArrayList<String>();
int start = 0;
boolean inQuotes = false;
for (int current = 0; current < input.length(); current++) {
    if (input.charAt(current) == '\"') inQuotes = !inQuotes; // toggle state
    else if (input.charAt(current) == ',' && !inQuotes) {
        result.add(input.substring(start, current));
        start = current + 1;
    }
}
result.add(input.substring(start));

If you don't care about preserving the commas inside the quotes you could simplify this approach (no handling of start index, no last character special case) by replacing your commas in quotes by something else and then split at commas:

String input = "foo,bar,c;qual=\"baz,blurb\",d;junk=\"quux,syzygy\"";
StringBuilder builder = new StringBuilder(input);
boolean inQuotes = false;
for (int currentIndex = 0; currentIndex < builder.length(); currentIndex++) {
    char currentChar = builder.charAt(currentIndex);
    if (currentChar == '\"') inQuotes = !inQuotes; // toggle state
    if (currentChar == ',' && inQuotes) {
        builder.setCharAt(currentIndex, ';'); // or '?', and replace later
    }
}
List<String> result = Arrays.asList(builder.toString().split(","));

you are using onclick which is javascript event. there is two ways

Javascript

<input type="button" value="Home" class="homebutton" id="btnHome" 
onClick="window.location = 'http://google.com'" />

Or PHP

create another page as redirect.php and put

<?php header('location : google.com') ?>

and insert this link on any page within the same directory

<a href="redirect.php">google<a/>

hope this helps its simplest!!

You can use ng-value-true to tell angular that your ng-model is a string.

I could only get ng-true-value working if I added the extra quotes like so (as shown in the official Angular docs - https://docs.angularjs.org/api/ng/input/input%5Bcheckbox%5D)

ng-true-value="'1'"

I solved this problem in the following way:

To upload files directly to Mongo DB you can make use of Grid FS. Although I will suggest you to upload the file anywhere in file system and put the image's url in the JSON object for every entry and then when you call the data for specific object you can call for the image using URL.

Tell me which backend technology are you using? I can give more suggestions based on that.

To simplify cleaning when using "out of source" build (i.e. you build in the build directory), I use the following script:

$ cat ~/bin/cmake-clean-build
#!/bin/bash

if [ -d ../build ]; then
    cd ..
    rm -rf build
    mkdir build
    cd build
else
    echo "build directory DOES NOT exist"
fi

Every time you need to clean up, you should source this script from the build directory:

. cmake-clean-build

its working with this code

text-align: justify; text-align-last: center;

I see this topic, but in my case I was looking for a way to improve the format. Using UFormat and adding -1 day

(get-date (get-date).addDays(-1) -UFormat "%Y%m%d-%H%M")

make sure you have same / higher API level installed on SDK packages with your devices.

example :

I have Android 2.3.4 on my Xperia Play. ADB wouldn't detect my device if theres only API 10 (Android 2.3.3) installed on my Mac. When i installed SDK 11 (Android 3.0) -- since I didn't found any SDK package for 2.3.4, the ADB working fine.

hope this help you.

First of all understand the mean of "without creating any new extra nodes", As I understand it does not mean that I can not have pointer(s) which points to an existing node(s).

You can not achieve it without talking pointers to existing nodes, even if you use recursion to achieve the same, system will create pointers for you as call stacks. It is just like telling system to add pointers which you have avoided in your code.

Simple function to achieve the same with taking extra pointers:

typedef struct _LLNode{
    int             value;
    struct _LLNode* next;
}LLNode;


LLNode* CombineSortedLists(LLNode* a,LLNode* b){
    if(NULL == a){
        return b;
    }
    if(NULL == b){
        return a;
    }
    LLNode* root  = NULL;
    if(a->value < b->value){
        root = a;
        a = a->next;
    }
    else{
        root = b;
        b    = b->next;
    }
    LLNode* curr  = root;
    while(1){
        if(a->value < b->value){
            curr->next = a;
            curr = a;
            a=a->next;
            if(NULL == a){
                curr->next = b;
                break;
            }
        }
        else{
            curr->next = b;
            curr = b;
            b=b->next;
            if(NULL == b){
                curr->next = a;
                break;
            }
        }
    }
    return root;
}

Use the CSS Class to prevent from Editing the Div Elements

CSS:

.divoverlay
{
position:absolute;
width:100%;
height:100%;
background-color:transparent;
z-index:1;
top:0;
}

JS:

$('#divName').append('<div class=divoverlay></div>');

Or add the class name in HTML Tag. It will prevent from editing the Div Elements.

Working with just one class:

select {
    width: 268px;
    padding: 5px;
    font-size: 16px;
    line-height: 1;
    border: 0;
    border-radius: 5px;
    height: 34px;
    background: url(http://cdn1.iconfinder.com/data/icons/cc_mono_icon_set/blacks/16x16/br_down.png) no-repeat right #ddd;
    -webkit-appearance: none;
    background-position-x: 244px;
}

http://jsfiddle.net/qhCsJ/4120/

Simple one:

var n = str.lastIndexOf(".");
return n > -1 ? str.substr(0, n) : str;

If you take a look at @types/node-fetch you will see the body definition

export class Body {
    bodyUsed: boolean;
    body: NodeJS.ReadableStream;
    json(): Promise<any>;
    json<T>(): Promise<T>;
    text(): Promise<string>;
    buffer(): Promise<Buffer>;
}

That means that you could use generics in order to achieve what you want. I didn't test this code, but it would looks something like this:

import { Actor } from './models/actor';

fetch(`http://swapi.co/api/people/1/`)
      .then(res => res.json<Actor>())
      .then(res => {
          let b:Actor = res;
      });

I found the following css in order to style a Bootstrap input for a jquery autocomplete:

https://gist.github.com/daz/2168334#file-style-scss

.ui-autocomplete {
    position: absolute;
    top: 100%;

    z-index: 1000;
    float: left;

    min-width: 160px;

    *border-right-width: 2px;
    *border-bottom-width: 2px;
}
.ui-menu-item > a.ui-corner-all {
    display: block;
    padding: 3px 15px;
    clear: both;
    font-weight: normal;
    line-height: 18px;
    color: #555555;
    white-space: nowrap;
}
.ui-state-hover, &.ui-state-active {

      -webkit-border-radius: 0px;

There is an xml attribute for it:

The classes of problem that are well suited for a mapreduce style solution are problems of aggregation. Of extracting data from a dataset. In C#, one could take advantage of LINQ to program in this style.

From the following article: http://codecube.net/2009/02/mapreduce-in-c-using-linq/

the GroupBy method is acting as the map, while the Select method does the job of reducing the intermediate results into the final list of results.

var wordOccurrences = words
                .GroupBy(w => w)
                .Select(intermediate => new
                {
                    Word = intermediate.Key,
                    Frequency = intermediate.Sum(w => 1)
                })
                .Where(w => w.Frequency > 10)
                .OrderBy(w => w.Frequency);

For the distributed portion, you could check out DryadLINQ: http://research.microsoft.com/en-us/projects/dryadlinq/default.aspx

To do the same I did following in terminal-

$ wget https://dl.pstmn.io/download/latest/linux64 -O postman.tar.gz
$ sudo tar -xzf postman.tar.gz -C /opt
$ rm postman.tar.gz
$ sudo ln -s /opt/Postman/Postman /usr/bin/postman

1. Now open file system, move to /usr/bin/ and search form "Postman"
2. There was a sh file with name 'Postman'
3. Double clicked on it which opened postman.
4. Locked icon to launcher on right clicking its icon for further use.

Hope will hell others too.

Why do you want to enforce that only a single thread can access the DB at any one time?

It is the job of the database driver to implement any necessary locking, assuming a Connection is only used by one thread at a time!

Most likely, your database is perfectly capable of handling multiple, parallel access

If you only want to animate the height of a view (from say 0 to a certain number) you could implement your own animation:

final View v = getTheViewToAnimateHere();
Animation anim=new Animation(){
    protected void applyTransformation(float interpolatedTime, Transformation t) {
        super.applyTransformation(interpolatedTime, t);
        // Do relevant calculations here using the interpolatedTime that runs from 0 to 1
        v.setLayoutParams(new LinearLayout.LayoutParams(LayoutParams.FILL_PARENT, (int)(30*interpolatedTime)));
    }};
anim.setDuration(500);
v.startAnimation(anim);

can you check your config file under ~/.aws/config- you might have an invalid section called [myname], something like this (this is an example)

[default]
region=us-west-2
output=json

[myname]
region=us-east-1
output=text

Just remove the [myname] section (including all content for this profile) and you will be fine to run aws cli again

You need to set the height of every parent element of the one you want the height defined.

<html style="height: 100%;">
  <body style="height: 100%;">
    <div style="height: 100%;">
      <p>
        Make this division 100% height.
      </p>
    </div>
  </body>
</html>

You are mixing pointers and arrays. If what you want is an array, then use an array:

struct test {
   static int data[10];        // array, not pointer!
};
int test::data[10] = { 1, 2, 3, 4, 5, 6, 7, 8, 9, 10 };

If on the other hand you want a pointer, the simplest solution is to write a helper function in the translation unit that defines the member:

struct test {
   static int *data;
};
// cpp
static int* generate_data() {            // static here is "internal linkage"
   int * p = new int[10];
   for ( int i = 0; i < 10; ++i ) p[i] = 10*i;
   return p;
}
int *test::data = generate_data();

HTML5 basically behaves as if the trailing slash is not there. There is no such thing as a self-closing tag in HTML5 syntax.

• Self-closing tags on non-void elements like <p/>, <div/> will not work at all. The trailing slash will be ignored, and these will be treated as opening tags. This is likely to lead to nesting problems.

  This is true regardless of whether there is whitespace in front of the slash: <p /> and <div /> also won't work for the same reason.

• Self-closing tags on void elements like <br/> or <img src="" alt=""/> will work, but only because the trailing slash is ignored, and in this case that happens to result in the correct behaviour.

The result is, anything that worked in your old "XHTML 1.0 served as text/html" will continue to work as it did before: trailing slashes on non-void tags were not accepted there either whereas the trailing slash on void elements worked.

One more note: it is possible to represent an HTML5 document as XML, and this is sometimes dubbed "XHTML 5.0". In this case the rules of XML apply and self-closing tags will always be handled. It would always need to be served with an XML mime type.

PHP mail() command does not support authentication. Your options:

From a face value they look same

In very simple terms, Factory Pattern, a Creational Pattern helps to create us an object - "Define an interface for creating an object". If we have a key value sort of object pool (e.g. Dictionary), passing the key to the Factory (I am referring to the Simple Factory Pattern) you can resolve the Type. Job done! Dependency Injection Framework (such as Structure Map, Ninject, Unity ...etc) on the other hand seems to be doing the same thing.

But... "Don't reinvent the wheel"

From a architectural perspective its a binding layer and "Don't reinvent the wheel".

For an enterprise grade application, concept of DI is more of a architectural layer which defines dependencies. To simplify this further you can think of this as a separate classlibrary project, which does dependency resolving. The main application depends on this project where Dependency resolver refers to other concrete implementations and to the dependency resolving.

Inaddition to "GetType/Create" from a Factory, most often than not we need more features (ability to use XML to define dependencies, mocking and unit testing etc.). Since you referred to Structure Map, look at the Structure Map feature list. It's clearly more than simply resolving simple object Mapping. Don't reinvent the wheel!

If all you have is a hammer, everything looks like a nail

Depending on your requirements and what type of application you build you need to make a choice. If it has just few projects (may be one or two..) and involves few dependencies, you can pick a simpler approach. It's like using ADO .Net data access over using Entity Framework for a simple 1 or 2 database calls, where introducing EF is an overkill in that scenario.

But for a larger project or if your project gets bigger, I would highly recommend to have a DI layer with a framework and make room to change the DI framework you use (Use a Facade in the Main App (Web App, Web Api, Desktop..etc.).

You can use wildcard to do this as following

ArrayList<String> strList = (ArrayList<String>)(ArrayList<?>)(list);

This is expected behavior for an uncaught exception with display_errors off.

Your options here are to turn on display_errors via php or in the ini file or catch and output the exception.

 ini_set("display_errors", 1);

or

 try{
     // code that may throw an exception
 } catch(Exception $e){
     echo $e->getMessage();
 }

If you are throwing exceptions, the intention is that somewhere further down the line something will catch and deal with it. If not it is a server error (500).

Another option for you would be to use set_exception_handler to set a default error handler for your script.

 function default_exception_handler(Exception $e){
          // show something to the user letting them know we fell down
          echo "<h2>Something Bad Happened</h2>";
          echo "<p>We fill find the person responsible and have them shot</p>";
          // do some logging for the exception and call the kill_programmer function.
 }
 set_exception_handler("default_exception_handler");

The question bears re-reading. The actual question asked is not similar to vendor prefixes in CSS properties, where future-proofing and thinking about vendor support and official standards is appropriate. The actual question asked is more akin to choosing URL query parameter names. Nobody should care what they are. But name-spacing the custom ones is a perfectly valid -- and common, and correct -- thing to do.

Rationale:
It is about conventions among developers for custom, application-specific headers -- "data relevant to their account" -- which have nothing to do with vendors, standards bodies, or protocols to be implemented by third parties, except that the developer in question simply needs to avoid header names that may have other intended use by servers, proxies or clients. For this reason, the "X-Gzip/Gzip" and "X-Forwarded-For/Forwarded-For" examples given are moot. The question posed is about conventions in the context of a private API, akin to URL query parameter naming conventions. It's a matter of preference and name-spacing; concerns about "X-ClientDataFoo" being supported by any proxy or vendor without the "X" are clearly misplaced.

There's nothing special or magical about the "X-" prefix, but it helps to make it clear that it is a custom header. In fact, RFC-6648 et al help bolster the case for use of an "X-" prefix, because -- as vendors of HTTP clients and servers abandon the prefix -- your app-specific, private-API, personal-data-passing-mechanism is becoming even better-insulated against name-space collisions with the small number of official reserved header names. That said, my personal preference and recommendation is to go a step further and do e.g. "X-ACME-ClientDataFoo" (if your widget company is "ACME").

IMHO the IETF spec is insufficiently specific to answer the OP's question, because it fails to distinguish between completely different use cases: (A) vendors introducing new globally-applicable features like "Forwarded-For" on the one hand, vs. (B) app developers passing app-specific strings to/from client and server. The spec only concerns itself with the former, (A). The question here is whether there are conventions for (B). There are. They involve grouping the parameters together alphabetically, and separating them from the many standards-relevant headers of type (A). Using the "X-" or "X-ACME-" prefix is convenient and legitimate for (B), and does not conflict with (A). The more vendors stop using "X-" for (A), the more cleanly-distinct the (B) ones will become.

Example:
Google (who carry a bit of weight in the various standards bodies) are -- as of today, 20141102 in this slight edit to my answer -- currently using "X-Mod-Pagespeed" to indicate the version of their Apache module involved in transforming a given response. Is anyone really suggesting that Google should use "Mod-Pagespeed", without the "X-", and/or ask the IETF to bless its use?

Summary:
If you're using custom HTTP Headers (as a sometimes-appropriate alternative to cookies) within your app to pass data to/from your server, and these headers are, explicitly, NOT intended ever to be used outside the context of your application, name-spacing them with an "X-" or "X-FOO-" prefix is a reasonable, and common, convention.

I shall write down my simple understanding of this two terms:

For quick understanding just read examples*

Dependency Injection(DI):
Dependency injection generally means passing an object on which method depends, as a parameter to a method, rather than having the method create the dependent object.
What it means in practice is that the method does not depends directly on a particular implementation; any implementation that meets the requirements can be passed as a parameter.

With this objects tell thier dependencies. And spring makes it available.
This leads to loosely coupled application development.

Quick Example:EMPLOYEE OBJECT WHEN CREATED,
              IT WILL AUTOMATICALLY CREATE ADDRESS OBJECT
   (if address is defines as dependency by Employee object)

Inversion of Control(IoC) Container:
This is common characteristic of frameworks, IOC manages java objects
– from instantiation to destruction through its BeanFactory.
-Java components that are instantiated by the IoC container are called beans, and the IoC container manages a bean's scope, lifecycle events, and any AOP features for which it has been configured and coded.

QUICK EXAMPLE:Inversion of Control is about getting freedom, more flexibility, and less dependency. When you are using a desktop computer, you are slaved (or say, controlled). You have to sit before a screen and look at it. Using keyboard to type and using mouse to navigate. And a bad written software can slave you even more. If you replaced your desktop with a laptop, then you somewhat inverted control. You can easily take it and move around. So now you can control where you are with your computer, instead of computer controlling it.

By implementing Inversion of Control, a software/object consumer get more controls/options over the software/objects, instead of being controlled or having less options.

Inversion of control as a design guideline serves the following purposes:

There is a decoupling of the execution of a certain task from implementation.
Every module can focus on what it is designed for.
Modules make no assumptions about what other systems do but rely on their contracts.
Replacing modules has no side effect on other modules
I will keep things abstract here, You can visit following links for detail understanding of the topic.

You could also just use the NSUUID API:

let uuid = NSUUID()

If you want to get the string value back out, you can use uuid.UUIDString.

Note that NSUUID is available from iOS 6 and up.

You can add a UITapGestureRecognizer to the imageView, just drag one into your Storyboard/xib, Ctrl-drag from the imageView to the gestureRecognizer, and Ctrl-drag from the gestureRecognizer to the Swift-file to make an IBAction.

You'll also need to enable user interactions on the UIImageView, as shown in this image:

replace(ltrim(replace(Fieldname.TableName, '0', '')), '', '0')

The suggestion from Thomas G worked for our needs.

The field in our case was already string and only the leading zeros needed to be trimmed. Mostly it's all numeric but sometimes there are letters so the previous INT conversion would crash.

relate to this suggestion : https://stackoverflow.com/a/20215481/3080835

also i had to add this to Application element in the Manifest:

<meta-data 
           android:name="com.google.android.gms.version" 
           android:value="@integer/google_play_services_version" />

and it worked perfectly.

typedef std::string::value_type char_t;

char_t up_char( char_t ch )
{
    return std::use_facet< std::ctype< char_t > >( std::locale() ).toupper( ch );
}

std::string toupper( const std::string &src )
{
    std::string result;
    std::transform( src.begin(), src.end(), std::back_inserter( result ), up_char );
    return result;
}

const std::string src  = "test test TEST";

std::cout << toupper( src );

You can also do it like this.
https://jsfiddle.net/Devashish2910/8hbosLj3/1/#&togetherjs=iugeGcColp

var str, result;
str = prompt("Enter Any Number");

var valueSplit = function (value, length) {
    if (length < 7) {
        var index = length - 3;
        return str.slice(0, index) + ',' + str.slice(index);
    }
    else if (length < 10 && length > 6) {
        var index1, index2;
        index1 = length - 6;
        index2 = length - 3;
        return str.slice(0,index1) + "," + str.slice(index1,index2) + "," + str.slice(index2);
    }
}

result = valueSplit(str, str.length);
alert(result);

Brief answer to your question: No. You shouldn't call ConfigureAwait(false) at the application level like that.

TL;DR version of the long answer: If you are writing a library where you don't know your consumer and don't need a synchronization context (which you shouldn't in a library I believe), you should always use ConfigureAwait(false). Otherwise, the consumers of your library may face deadlocks by consuming your asynchronous methods in a blocking fashion. This depends on the situation.

Here is a bit more detailed explanation on the importance of ConfigureAwait method (a quote from my blog post):

When you are awaiting on a method with await keyword, compiler generates bunch of code in behalf of you. One of the purposes of this action is to handle synchronization with the UI (or main) thread. The key component of this feature is the SynchronizationContext.Current which gets the synchronization context for the current thread. SynchronizationContext.Current is populated depending on the environment you are in. The GetAwaiter method of Task looks up for SynchronizationContext.Current. If current synchronization context is not null, the continuation that gets passed to that awaiter will get posted back to that synchronization context.

When consuming a method, which uses the new asynchronous language features, in a blocking fashion, you will end up with a deadlock if you have an available SynchronizationContext. When you are consuming such methods in a blocking fashion (waiting on the Task with Wait method or taking the result directly from the Result property of the Task), you will block the main thread at the same time. When eventually the Task completes inside that method in the threadpool, it is going to invoke the continuation to post back to the main thread because SynchronizationContext.Current is available and captured. But there is a problem here: the UI thread is blocked and you have a deadlock!

Also, here are two great articles for you which are exactly for your question:

• The Perfect Recipe to Shoot Yourself in The Foot - Ending up with a Deadlock Using the C# 5.0 Asynchronous Language Features
• Asynchronous .NET Client Libraries for Your HTTP API and Awareness of async/await's Bad Effects

Finally, there is a great short video from Lucian Wischik exactly on this topic: Async library methods should consider using Task.ConfigureAwait(false).

Hope this helps.

Keep it simple :

/**
 * This function will take an URL as input and return the file name.
 * <p>Examples :</p>
 * <ul>
 * <li>http://example.com/a/b/c/test.txt -> test.txt</li>

 * </ul>
 *

    String urlString = url.getFile();

    return urlString.substring(urlString.lastIndexOf('/') + 1).split("\\?")[0].split("#")[0];
}

Primarily it's because jQuery moves the dialog outside of the form tags using the DOM. Move it back inside the form tags and it should work fine. You can see this by inspecting the element in Firefox.

gcc actually can do this optimization, even for floating-point numbers. For example,

double foo(double a) {
  return a*a*a*a*a*a;
}

becomes

foo(double):
    mulsd   %xmm0, %xmm0
    movapd  %xmm0, %xmm1
    mulsd   %xmm0, %xmm1
    mulsd   %xmm1, %xmm0
    ret

with -O -funsafe-math-optimizations. This reordering violates IEEE-754, though, so it requires the flag.

Signed integers, as Peter Cordes pointed out in a comment, can do this optimization without -funsafe-math-optimizations since it holds exactly when there is no overflow and if there is overflow you get undefined behavior. So you get

foo(long):
    movq    %rdi, %rax
    imulq   %rdi, %rax
    imulq   %rdi, %rax
    imulq   %rax, %rax
    ret

with just -O. For unsigned integers, it's even easier since they work mod powers of 2 and so can be reordered freely even in the face of overflow.

I had the same issue where my firewall was configured properly, TCP/IP was enabled in SQL Server Configuration Manager but I still could not access my SQL database from outside the computer hosting it. I found the solution was SQL Server Browser was disabled by default in Services (and no option was available to enable it in SQL Server Configuration Manager).

I enabled it by Control Panel > Administrative Tools > Services then double click on SQL Server Browser. In the General tab set the startup type to Automatic using the drop down list. Then go back into SQL Server Configuration Manager and check that the SQL Server Browser is enabled. Hope this helps.

Simply select the class, right click and choose rename (probably F2 will also do). You can also select the class name in the source file, right click, choose Source, Refactor and rename. In both cases, both the class and the filename will be changed.

for the most basic read of a text file, use open

example:

Dim FileNum As Integer
Dim DataLine As String

FileNum = FreeFile()
Open "Filename" For Input As #FileNum

While Not EOF(FileNum)
    Line Input #FileNum, DataLine ' read in data 1 line at a time
    ' decide what to do with dataline, 
    ' depending on what processing you need to do for each case

Double.ToString()

Have a look in the examples for a number of different formating options Double.ToString(string)

This script logs all the file names and ids in the drive:

// Log the name and id of every file in the user's Drive
function listFiles() {
  var files = DriveApp.getFiles();
  while ( files.hasNext() ) {
    var file = files.next();
    Logger.log( file.getName() + ' ' + file.getId() );
  }
}  

Also, the "Files: list" page has a form at the end that lists the metadata of all the files in the drive, that can be used in case you need but a few ids.

As mentioned, sealed is an equivalent of final for methods and classes.

As for the rest, it is complicated.

• For static final fields, static readonly is the closest thing possible. It allows you to initialize the static field in a static constructor, which is fairly similar to static initializer in Java. This applies both to constants (primitives and immutable objects) and constant references to mutable objects.

  The const modifier is fairly similar for constants, but you can't set them in a static constructor.

• On a field that shouldn't be reassigned once it leaves the constructor, readonly can be used. It is not equal though - final requires exactly one assignment even in constructor or initializer.

• There is no C# equivalent for a final local variable that I know of. If you are wondering why would anyone need it: You can declare a variable prior to an if-else, switch-case or so. By declaring it final, you enforce that it is assigned at most once.

  Java local variables in general are required to be assigned at least once before they are read. Unless the branch jumps out before value read, a final variable is assigned exactly once. All of this is checked compile-time. This requires well behaved code with less margin for an error.

Summed up, C# has no direct equivalent of final. While Java lacks some nice features of C#, it is refreshing for me as mostly a Java programmer to see where C# fails to deliver an equivalent.

In case somebody is running into this while trying to debug a Unit Test or Run a unit test I had to kill the following two processes in order for it to release the file:

        WebResource webResource = client.resource("http://localhost:8080/your-app/rest/data/post");

        String input = "{\"message\":\"Hello\"}";

        ClientResponse response = webResource.type("application/json")
           .post(ClientResponse.class, input);

        if (response.getStatus() != 201) {
            throw new RuntimeException("Failed : HTTP error code : "
                 + response.getStatus());
        }

        System.out.println("Output from Server .... \n");
        String output = response.getEntity(String.class);
        System.out.println(output);

      } catch (Exception e) {

        e.printStackTrace();

      }

    }
}

This works for me:

'atom-workspace atom-text-editor':
    'ctrl-alt-a': 'editor:auto-indent'

You have to select all with ctrl-a first.

Attributed String Programming Guide:

UIFont *font = [UIFont fontWithName:@"Palatino-Roman" size:14.0];
NSDictionary *attrsDictionary = [NSDictionary dictionaryWithObject:font
                                forKey:NSFontAttributeName];
NSAttributedString *attrString = [[NSAttributedString alloc] initWithString:@"strigil" attributes:attrsDictionary];

Update: I tried to use addAttribute: method in my own app, but it seemed to be not working on the iOS 6 Simulator:

NSLog(@"%@", textView.attributedText);

The log seems to show correctly added attributes, but the view on iOS simulator was not display with attributes.

Yes, you can do that which returns boolean. The following java code in WebDriver with TestNG or JUnit can do:

protected boolean isTextPresent(String text){
    try{
        boolean b = driver.getPageSource().contains(text);
        return b;
    }
    catch(Exception e){
        return false;
    }
  }

Now call the above method as below:

assertTrue(isTextPresent("Your text"));

Or, there is another way. I think, this is the better way:

private StringBuffer verificationErrors = new StringBuffer();
try {
                  assertTrue(driver.findElement(By.cssSelector("BODY")).getText().matches("^[\\s\\S]*    Your text here\r\n\r\n[\\s\\S]*$"));
  } catch (Error e) {
     verificationErrors.append(e.toString());
   }

I needed this feature just form my app 'models' (raw backend data converted to objects). So I ended up using a combination of Object.create (create new object from specified prototype) and Object.assign (copy properties between objects). Need to handle the deep copy manually. I created a gist for this.

Another approach is to first do a searchType: 'count', then and then do a normal search with size set to results.count.

The advantage here is it avoids depending on a magic number for UPPER_BOUND as suggested in this similar SO question, and avoids the extra overhead of building too large of a priority queue that Shay Banon describes here. It also lets you keep your results sorted, unlike scan.

The biggest disadvantage is that it requires two requests. Depending on your circumstance, this may be acceptable.

You are right. This is a badly documented issue. But you can change the font size parameter (by opposition to font scale) directly after building the plot. Check the following example:

import seaborn as sns
tips = sns.load_dataset("tips")

b = sns.boxplot(x=tips["total_bill"])
b.axes.set_title("Title",fontsize=50)
b.set_xlabel("X Label",fontsize=30)
b.set_ylabel("Y Label",fontsize=20)
b.tick_params(labelsize=5)
sns.plt.show()

, which results in this:

To make it consistent in between plots I think you just need to make sure the DPI is the same. By the way it' also a possibility to customize a bit the rc dictionaries since "font.size" parameter exists but I'm not too sure how to do that.

NOTE: And also I don't really understand why they changed the name of the font size variables for axis labels and ticks. Seems a bit un-intuitive.

API(Application Programming Interface), the full form itself suggests that its an Interface which allows you to program for your application with the help or support of some other Application's Interface which exposes some sort of functionality which is useful to your application.

E.g showing updated currency exchange rates on your website would need some third party Interface to program against unless you plan to have your own database with currency rates and regular updates to the same. This set of functionality is when already available with some one else and when they want to share it with others they have to have an endpoint to communicate with the others who are interested in such interactions so they deploy it on web by the means of web-services. This end point is nothing but interface of their application which you can program against hence API.

I tried working with the string form rather than the number and this seemed to work. I have only tested this on Chrome but it should be universal:

function removeExponent(s) {
    var ie = s.indexOf('e');
    if (ie != -1) {
        if (s.charAt(ie + 1) == '-') {
            // negative exponent, prepend with .0s
            var n = s.substr(ie + 2).match(/[0-9]+/);
            s = s.substr(2, ie - 2); // remove the leading '0.' and exponent chars
            for (var i = 0; i < n; i++) {
                s = '0' + s;
            }
            s = '.' + s;
        } else {
            // positive exponent, postpend with 0s
            var n = s.substr(ie + 1).match(/[0-9]+/);
            s = s.substr(0, ie); // strip off exponent chars            
            for (var i = 0; i < n; i++) {
                s += '0';
            }       
        }
    }
    return s;
}

First, install with git+git or git+https, in any way you know. Example of installing kronok's branch of the brabeion project:

pip install -e git+https://github.com/kronok/brabeion.git@12efe6aa06b85ae5ff725d3033e38f624e0a616f#egg=brabeion

Second, use pip freeze > requirements.txt to get the right thing in your requirements.txt. In this case, you will get

-e git+https://github.com/kronok/brabeion.git@12efe6aa06b85ae5ff725d3033e38f624e0a616f#egg=brabeion-master

Third, test the result:

pip uninstall brabeion
pip install -r requirements.txt

In Python 3, urllib.quote has been moved to urllib.parse.quote and it does handle unicode by default.

>>> from urllib.parse import quote
>>> quote('/test')
'/test'
>>> quote('/test', safe='')
'%2Ftest'
>>> quote('/El Niño/')
'/El%20Ni%C3%B1o/'

Perfect solution I have tried it and succeed to get my index page when I have append this code in my site configuration file.

location / {
            try_files $uri $uri/ /index.php;
}

In configuration file itself explained that at "First attempt to serve request as file, then as directory, then fall back to index.html in my case it is index.php as I am providing page through php code.

You add a

float: left;

to the style of the 3 elements and make sure the parent container has

overflow: hidden; position: relative;

this makes sure the floats take up actual space.

<html>
    <head>
        <title>Website Title </title>
    </head>
    <body>
        <div id="the-whole-thing" style="position: relative; overflow: hidden;">
            <div id="leftThing" style="position: relative; width: 25%; background-color: blue; float: left;">
                Left Side Menu
            </div>
            <div id="content" style="position: relative; width: 50%; background-color: green; float: left;">
                Random Content
            </div>
            <div id="rightThing" style="position: relative; width: 25%; background-color: yellow; float: left;">
                Right Side Menu
            </div>
        </div>
    </body>
</html>

Also please note that the width: 100% and height: 100% need to be removed from the container, otherwise the 3rd block will wrap to a 2nd line.

If you have Python 2.6 installed then you already have simplejson - just import json; it's the same thing.

As previously some people have said, HTTPS brings security.

However, POST is a bit more safe than GET because GET could be stored in the history.

But even more, sadly, sometimes the election of POST or GET is not up to the developer. For example a hyperlink is always send by GET (unless its transformed into a post form using javascript).

I have scopes for this, hope it help somebody. https://laravel.com/docs/master/eloquent#local-scopes

public function scopeWhereLike($query, $column, $value)
{
    return $query->where($column, 'like', '%'.$value.'%');
}

public function scopeOrWhereLike($query, $column, $value)
{
    return $query->orWhere($column, 'like', '%'.$value.'%');
}

Usage:

$result = BookingDates::whereLike('email', $email)->orWhereLike('name', $name)->get();

In order to install Android Studio on Ubuntu Studio 14.04 and derivatives, do the following:

Step 1: Open a terminal using the Dash or pressing Ctrl + Alt + T keys.

Step 2: If you have not, add that repository with the following command:

sudo add-apt-repository ppa:paolorotolo/android-studio

Step 3: Update the APT with the command:

sudo apt-get update

Step 4: Now install the program with the command:

sudo apt-get install android-studio

Step 5: Once installed, run the program by typing in Dash:

studio

This can also be caused by leaving the Services console open. Windows won't actually delete the service until it is closed.

This an example from my code how to address a widget(button) in popupwindow

View v=LayoutInflater.from(getContext()).inflate(R.layout.popupwindow, null, false);
    final PopupWindow pw = new PopupWindow(v,500,500, true);
    final Button button = rootView.findViewById(R.id.button);
    button.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            pw.showAtLocation(rootView.findViewById(R.id.constraintLayout), Gravity.CENTER, 0, 0);


        }
    });
    final Button popup_btn=v.findViewById(R.id.popupbutton);

    popup_btn.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            popup_btn.setBackgroundColor(Color.RED);
        }
    });

Hope this help you

Or use this

- (void)insertSubview:(UIView *)view belowSubview:(UIView*)siblingSubview;

as per here

Not the most elegant, but I do (for Python 3):

if hasattr(instance, '__iter__') and not isinstance(instance, (str, bytes)):
    ...

This allows other iterables (like Django querysets) but excludes strings and bytestrings. I typically use this in functions that accept either a single object ID or a list of object IDs. Sometimes the object IDs can be strings and I don't want to iterate over those character by character. :)

This question is not specific to jQuery, but specific to JavaScript in general. The core problem is how to "channel" a variable in embedded functions. This is the example:

var abc = 1; // we want to use this variable in embedded functions

function xyz(){
  console.log(abc); // it is available here!
  function qwe(){
    console.log(abc); // it is available here too!
  }
  ...
};

This technique relies on using a closure. But it doesn't work with this because this is a pseudo variable that may change from scope to scope dynamically:

// we want to use "this" variable in embedded functions

function xyz(){
  // "this" is different here!
  console.log(this); // not what we wanted!
  function qwe(){
    // "this" is different here too!
    console.log(this); // not what we wanted!
  }
  ...
};

What can we do? Assign it to some variable and use it through the alias:

var abc = this; // we want to use this variable in embedded functions

function xyz(){
  // "this" is different here! --- but we don't care!
  console.log(abc); // now it is the right object!
  function qwe(){
    // "this" is different here too! --- but we don't care!
    console.log(abc); // it is the right object here too!
  }
  ...
};

this is not unique in this respect: arguments is the other pseudo variable that should be treated the same way — by aliasing.

First, create a quick function that will split a delimited list of values into a table, like this:

CREATE FUNCTION dbo.udf_SplitVariable
(
    @List varchar(8000),
    @SplitOn varchar(5) = ','
)

RETURNS @RtnValue TABLE
(
    Id INT IDENTITY(1,1),
    Value VARCHAR(8000)
)

AS
BEGIN

--Account for ticks
SET @List = (REPLACE(@List, '''', ''))

--Account for 'emptynull'
IF LTRIM(RTRIM(@List)) = 'emptynull'
BEGIN
    SET @List = ''
END

--Loop through all of the items in the string and add records for each item
WHILE (CHARINDEX(@SplitOn,@List)>0)
BEGIN

    INSERT INTO @RtnValue (value)
    SELECT Value = LTRIM(RTRIM(SUBSTRING(@List, 1, CHARINDEX(@SplitOn, @List)-1)))  

    SET @List = SUBSTRING(@List, CHARINDEX(@SplitOn,@List) + LEN(@SplitOn), LEN(@List))

END

INSERT INTO @RtnValue (Value)
SELECT Value = LTRIM(RTRIM(@List))

RETURN

END 

Then call the function like this...

SELECT * 
FROM A
LEFT OUTER JOIN udf_SplitVariable(@ExcludedList, ',') f ON A.Id = f.Value
WHERE f.Id IS NULL

This has worked really well on our project...

Of course, the opposite could also be done, if that was the case (though not your question).

SELECT * 
FROM A
INNER JOIN udf_SplitVariable(@ExcludedList, ',') f ON A.Id = f.Value

And this really comes in handy when dealing with reports that have an optional multi-select parameter list. If the parameter is NULL you want all values selected, but if it has one or more values you want the report data filtered on those values. Then use SQL like this:

SELECT * 
FROM A
INNER JOIN udf_SplitVariable(@ExcludedList, ',') f ON A.Id = f.Value OR @ExcludeList IS NULL

This way, if @ExcludeList is a NULL value, the OR clause in the join becomes a switch that turns off filtering on this value. Very handy...

for(n in 1:5) {
  if(n==3) next # skip 3rd iteration and go to next iteration
  cat(n)
}

One can use a plain ImageView in his xml and make it clickable (android:clickable="true")? You only have to use as src an image that has been shaped like a button i.e round corners.

I ended up using:

/usr/bin/time -ao output_file.txt -f "Operation took: %E" echo lol

• Where "a" is append
• Where "o" is proceeded by the file name to append to
• Where "f" is format with a printf-like syntax
• Where "%E" produces 0:00:00; hours:minutes:seconds
• I had to invoke /usr/bin/time because the bash "time" was trampling it and doesn't have the same options
• I was just trying to get output to file, not the same thing as OP

getJSON will evaluate the data to JSON for you, as long as the correct content-type is used. Make sure that the server is returning the data as application/json.

$user->data is an array of objects. Each element in the array has a name and value property (as well as others).

Try putting the 2nd foreach inside the 1st.

foreach($user->data as $mydata)
{
    echo $mydata->name . "\n";
    foreach($mydata->values as $values)
    {
        echo $values->value . "\n";
    }
}

You can do it without explicit loops by using stream iterators. I'm sure that it uses some kind of loop internally.

#include <string>
#include <iostream>
#include <istream>
#include <ostream>
#include <iterator>

int main()
{
// don't skip the whitespace while reading
  std::cin >> std::noskipws;

// use stream iterators to copy the stream to a string
  std::istream_iterator<char> it(std::cin);
  std::istream_iterator<char> end;
  std::string results(it, end);

  std::cout << results;
}

I solved my problem by upgrading my .NetFramework version from 4.5.2 to 4.7.2.

document.getElementById("TestToggleRadioButtonList").rows[0].cells[0].childNodes[0].checked = true;

where TestToggleRadioButtonList is the id of the RadioButtonList.

Just in case :

For example, I just tryed <span class="icones glyphicon glyphicon-pen"> and after one hour i realized that this icon was not included in the bootstrap pack !! While the enveloppe icon was working fine..

Hope this helps

I always assumed it had to do with this line of the zen of python:

There should be one — and preferably only one — obvious way to do it.

x++ and x+=1 do the exact same thing, so there is no reason to have both.

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

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

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

following is sample code

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

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

Helpful Progamming Tips and Hacks

Without @Transactional annotation you can achieve the same goal with finding the entity from the DB and then removing that entity you got from the DB.

CrudRepositor -> void delete(T var1);

char c = '1';
int i = (int)(c-'0');

and you can create a static method out of it:

static int ToInt(this char c)
{
    return (int)(c - '0');
}

There's no NotifyIcon for WPF.
