You can simply do this with a bool:

if int(number) == float(number):

   number = int(number)

else:

   number = float(number)

The behavior you're seeing is due to how ggplot2 deals with data that are outside the axis ranges of the plot. You can change this behavior depending on whether you use scale_y_continuous (or, equivalently, ylim) or coord_cartesian to set axis ranges, as explained below.

library(ggplot2)

# All points are visible in the plot
ggplot(mtcars, aes(mpg, hp)) + 
  geom_point()

In the code below, one point with hp = 335 is outside the y-range of the plot. Also, because we used scale_y_continuous to set the y-axis range, this point is not included in any other statistics or summary measures calculated by ggplot, such as the linear regression line.

ggplot(mtcars, aes(mpg, hp)) + 
  geom_point() +
  scale_y_continuous(limits=c(0,300)) +  # Change this to limits=c(0,335) and the warning disappars
  geom_smooth(method="lm")

Warning messages:
1: Removed 1 rows containing missing values (stat_smooth). 
2: Removed 1 rows containing missing values (geom_point).

In the code below, the point with hp = 335 is still outside the y-range of the plot, but this point is nevertheless included in any statistics or summary measures that ggplot calculates, such as the linear regression line. This is because we used coord_cartesian to set the y-axis range, and this function does not exclude points that are outside the plot ranges when it does other calculations on the data.

If you compare this and the previous plot, you can see that the linear regression line in the second plot has a slightly steeper slope, because the point with hp=335 is included when calculating the regression line, even though it's not visible in the plot.

ggplot(mtcars, aes(mpg, hp)) + 
  geom_point() +
  coord_cartesian(ylim=c(0,300)) +
  geom_smooth(method="lm")

F5 triggers a standard reload.

Ctrl + F5 triggers a forced reload. This causes the browser to re-download the page from the web server, ensuring that it always has the latest copy.

Unlike with F5, a forced reload does not display a cached copy of the page.

data = [150,300]; // data from ajax or any other way chart.series[0].setData(data, true);

The setData will call redraw method.

If you have an Order class, adding a property that references another class in your model, for instance Customer should be enough to let EF know there's a relationship in there:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    public virtual Customer Customer { get; set; }
}

You can always set the FK relation explicitly:

public class Order
{
    public int ID { get; set; }

    // Some other properties

    // Foreign key to customer
    [ForeignKey("Customer")]
    public string CustomerID { get; set; }
    public virtual Customer Customer { get; set; }
}

The ForeignKeyAttribute constructor takes a string as a parameter: if you place it on a foreign key property it represents the name of the associated navigation property. If you place it on the navigation property it represents the name of the associated foreign key.

What this means is, if you where to place the ForeignKeyAttribute on the Customer property, the attribute would take CustomerID in the constructor:

public string CustomerID { get; set; }
[ForeignKey("CustomerID")]
public virtual Customer Customer { get; set; }

EDIT based on Latest Code You get that error because of this line:

[ForeignKey("Parent")]
public Patient Patient { get; set; }

EF will look for a property called Parent to use it as the Foreign Key enforcer. You can do 2 things:

1) Remove the ForeignKeyAttribute and replace it with the RequiredAttribute to mark the relation as required:

[Required]
public virtual Patient Patient { get; set; }

Decorating a property with the RequiredAttribute also has a nice side effect: The relation in the database is created with ON DELETE CASCADE.

I would also recommend making the property virtual to enable Lazy Loading.

2) Create a property called Parent that will serve as a Foreign Key. In that case it probably makes more sense to call it for instance ParentID (you'll need to change the name in the ForeignKeyAttribute as well):

public int ParentID { get; set; }

In my experience in this case though it works better to have it the other way around:

[ForeignKey("Patient")]
public int ParentID { get; set; }

public virtual Patient Patient { get; set; }

Its really working if we use Doctype on our web page jquery(window) will return the viewport height else it will return the complete document height.

Define the following tag on the top of your web page: <!DOCTYPE html>

try removing the extra '/' after the operation name (authentication) when invoking through the client

/axis2/services/MyService/authentication?username=Denise345&password=xxxxx

In your example, the compiler has no way of knowing what type should TModel be. You could do something close to what you are probably trying to do with an extension method.

static class ModelExtensions
{
   public static IDictionary<string, object> GetHtmlAttributes<TModel, TProperty>
      (this TModel model, Expression<Func<TModel, TProperty>> propertyExpression)
   {
       return new Dictionary<string, object>();
   }
}

But you wouldn't be able to have anything similar to virtual, I think.

EDIT:

Actually, you can do virtual, using self-referential generics:

class ModelBase<TModel>
{
    public virtual IDictionary<string, object> GetHtmlAttributes<TProperty>
        (Expression<Func<TModel, TProperty>> propertyExpression)
    {
        return new Dictionary<string, object>();
    }
}

class FooModel : ModelBase<FooModel>
{
    public override IDictionary<string, object> GetHtmlAttributes<TProperty>
        (Expression<Func<FooModel, TProperty>> propertyExpression)
    {
        return new Dictionary<string, object> { { "foo", "bar" } };
    }
}

Select the Body using chrome dev tools (Inspect ) and change in css overflow:visible,

If that doesn't work then check in below css file if html, body is set as overflow:hidden , change it as visible

The beauty of C++, like C, is that the sized of these things are implementation-defined, so there's no correct answer without your specifying the compiler you're using. Are those two the same? Yes. "long long" is a synonym for "long long int", for any compiler that will accept both.

For those of you developing regular websites or PWAs (Progressive Web Apps) for mobile devices and/or laptops/monitors with touch screens, then you have landed here because you might be used to mouse events and are new to the sometimes painful experience of Touch events... yay!

There are just 3 rules:

1. Do as little as possible during mousemove or touchmove events.
2. Do as much as possible during mousedown or touchstart events.
3. Cancel propagation and prevent defaults for touch events to prevent mouse events from also firing on hybrid devices.

Needless to say, things are more complicated with touch events because there can be more than one and they're more flexible (complicated) than mouse events. I'm only going to cover a single touch here. Yes, I'm being lazy, but it's the most common type of touch, so there.

Prefer using Vue.js? I do! Then your HTML would look like this:

     @mousemove="handleMouseMove"
     @mouseup="handleMouseUp"
     @touchstart.stop.prevent="handleTouchStart"
     @touchmove.stop.prevent="handleTouchMove"

Suppose we have variable date , month and year then we can write it in the java like this.

int date=15,month=4,year=2016;
System.out.println(date+ "/"+month+"/"+year);

output of this will be like below:

15/4/2016

I have not seen the following solution among the answers, so I thought I'd put it out there.

The problem is to select rows which are the first rows when ordered by AnotherColumn in all groups grouped by SomeColumn.

The following solution will do this in MySQL. id has to be a unique column which must not hold values containing - (which I use as a separator).

select t1.*
from mytable t1
inner join (
  select SUBSTRING_INDEX(
    GROUP_CONCAT(t3.id ORDER BY t3.AnotherColumn DESC SEPARATOR '-'),
    '-', 
    1
  ) as id
  from mytable t3
  group by t3.SomeColumn
) t2 on t2.id = t1.id


-- Where 
SUBSTRING_INDEX(GROUP_CONCAT(id order by AnotherColumn desc separator '-'), '-', 1)
-- can be seen as:
FIRST(id order by AnotherColumn desc)

-- For completeness sake:
SUBSTRING_INDEX(GROUP_CONCAT(id order by AnotherColumn desc separator '-'), '-', -1)
-- would then be seen as:
LAST(id order by AnotherColumn desc)

There is a feature request for FIRST() and LAST() in the MySQL bug tracker, but it was closed many years back.

Got the same error recently but was able to fixed it by ensuring to close every wcf client call. eg.

WCFServiceClient client = new WCFServiceClient ();
//More codes here
// Always close the client.
client.Close();

or

using(WCFServiceClient client = new WCFServiceClient ())
{ 
    //More codes here 
}

Make sure all your links that you want to stop have href="#!" (or anything you want, really), and then use this:

jq('body').on('click.stop_link', 'a[href="#!"]',
function(event) {
     event.preventDefault();
});

Use:

1..10 | % { write "loop $_" }

Output:

PS D:\temp> 1..10 | % { write "loop $_" }
loop 1
loop 2
loop 3
loop 4
loop 5
loop 6
loop 7
loop 8
loop 9
loop 10

I got this error when I was trying to access a property of a singleton's struct instance from a 'static scope' within that singleton (that contains constants inside an enum that are never instantiated)

Might be your project is not JEE nature, to do this Right Click -> Properties -> Project Facets and click Convert to facet and check dynamic web module and ok. Now you will be able to see Java EE Tools.

You can always append the '%' by itself without any other format specifiers in the string you are appending, like so...

int test = 10;

NSString *stringTest = [NSString stringWithFormat:@"%d", test];
stringTest = [stringTest stringByAppendingString:@"%"];
NSLog(@"%@", stringTest);

For iOS7.0+

To expand the answer to other characters that might cause you conflict you may choose to use:

- (NSString *)stringByAddingPercentEncodingWithAllowedCharacters:(NSCharacterSet *)allowedCharacters

Written out step by step it looks like this:

int test = 10;

NSString *stringTest = [NSString stringWithFormat:@"%d", test];
stringTest = [[stringTest stringByAppendingString:@"%"] 
             stringByAddingPercentEncodingWithAllowedCharacters:
             [NSCharacterSet alphanumericCharacterSet]];
stringTest = [stringTest stringByRemovingPercentEncoding];

NSLog(@"percent value of test: %@", stringTest);

Or short hand:

NSLog(@"percent value of test: %@", [[[[NSString stringWithFormat:@"%d", test] 
stringByAppendingString:@"%"] stringByAddingPercentEncodingWithAllowedCharacters:
[NSCharacterSet alphanumericCharacterSet]] stringByRemovingPercentEncoding]);

I recommend you take a look at the list of editors on Python's wiki, as well as these related questions:

• What IDE to use for Python?
• Which editor/IDE should I use for Python?

How about just Dir.mkdir('dir') rescue nil ?

var test_obj = from d in repository.DbPricing
join d1 in repository.DbOfficeProducts on d.OfficeProductId equals d1.Id
join d2 in repository.DbOfficeProductDetails on d1.ProductDetailsId equals d2.Id

    {
    PricingId = d.Id,
    LetterColor = d2.LetterColor,
    LetterPaperWeight = d2.LetterPaperWeight
    };

In the latest version of the SDK, you would use the setBackgroundResource method.

public void onClick(View v) {
   if(v == ButtonName) {
     ButtonName.setBackgroundResource(R.drawable.ImageResource);
   }
}

In JavaScript multiple ways are there, below are some of them

Method 1:

throw new Error("Something went badly wrong!");

Method 2:

return;

Method 3:

return false;

Method 4:

new new

Method 5:

write your custom function use above method and call where you needed

Note: If you want to just pause the code execution you can use

debugger; 

You are getting the error because $ret is not an array.

To get rid of the error, at the start of your function, define it with this line: $ret = array();

It appears that the get_tags() call is returning nothing, so the foreach is not run, which means that $ret isn't defined.

The way to do it is with ternary operator:

name = city.getName() == null ? city.getName() : "N/A"

However, I believe you have a typo in your code above, and you mean to say:

if (city.getName() != null) ...

try this:

struct Pos{
    int x;
    int y;

    inline Pos& operator=(const Pos& other){
        x=other.x;
        y=other.y;
        return *this;
    }

    inline Pos operator+(const Pos& other) const {
        Pos res {x+other.x,y+other.y};
        return res;
    }

    const inline bool operator==(const Pos& other) const {
        return (x==other.x and y == other.y);
    }
 };  

Generate random 16-byte ID containig letters, digits, '_' and '-'

os.urandom(16).translate((f'{string.ascii_letters}{string.digits}-_'*4).encode('ascii'))

The portable way to do this is:

sed -e 's/[ \t][ \t]*/\
/g'

That's an actual newline between the backslash and the slash-g. Many sed implementations don't know about \n, so you need a literal newline. The backslash before the newline prevents sed from getting upset about the newline. (in sed scripts the commands are normally terminated by newlines)

With GNU sed you can use \n in the substitution, and \s in the regex:

sed -e 's/\s\s*/\n/g'

GNU sed also supports "extended" regular expressions (that's egrep style, not perl-style) if you give it the -r flag, so then you can use +:

sed -r -e 's/\s+/\n/g'

If this is for Linux only, you can probably go with the GNU command, but if you want this to work on systems with a non-GNU sed (eg: BSD, Mac OS-X), you might want to go with the more portable option.

Here's what I've got so far (found it on the page Ben Alpert mentioned):

SELECT REPLACE(
    SUBSTRING(
        SUBSTRING_INDEX(c.`courseNames`, ',', e.`courseId` + 1)
        , LENGTH(SUBSTRING_INDEX(c.`courseNames`, ',', e.`courseId`)
    ) + 1)
    , ','
    , ''
)
FROM `clients` c INNER JOIN `clientenrols` e USING (`clientId`)

For Google chrome it is not Ctrl+F5. It's Shift+F5 to clear the current cache! It works for me !

Working with this excellent answer, you can check the active element (the button), append a hidden input to the form, and optionally remove it at the end of the submit handler.

$('form.form-js').submit(function(event){
    var frm = $(this);
    var btn = $(document.activeElement);
    if(
        btn.length &&
        frm.has(btn) &&
        btn.is('button[type="submit"], input[type="submit"], input[type="image"]') &&
        btn.is('[name]')
    ){
        frm.append('<input type="hidden" id="form-js-temp" name="' + btn.attr('name') + '" value="' + btn.val() + '">');
    }

    // Handle the form submit here

    $('#form-js-temp').remove();
});

Side note: I personally add the class form-js on all forms that are submitted via JavaScript.

Try this:

ggplot(data=dat, aes(x=Types, y=Number, fill=sample)) + 
     geom_bar(position = 'dodge', stat='identity') +
     geom_text(aes(label=Number), position=position_dodge(width=0.9), vjust=-0.25)

When building requests for web services, I find doing something like the following is very easy and makes concatenation readable in Xcode:

NSString* postBody = {
    @"<?xml version=\"1.0\" encoding=\"utf-8\"?>"
    @"<soap:Envelope xmlns:xsi=\"http://www.w3.org/2001/XMLSchema-instance\" xmlns:xsd=\"http://www.w3.org/2001/XMLSchema\" xmlns:soap=\"http://schemas.xmlsoap.org/soap/envelope/\">"
    @" <soap:Body>"
    @"  <WebServiceMethod xmlns=\"\">"
    @"   <parameter>test</parameter>"
    @"  </WebServiceMethod>"
    @" </soap:Body>"
    @"</soap:Envelope>"
};

Another option would be to enable the management_plugin and connect to it over a browser. You can see all queues and information about them. It is possible and simple to delete queues from this interface.

TryParse is faster...

The first of these functions, Parse, is one that should be familiar to any .Net developer. This function will take a string and attempt to extract an integer out of it and then return the integer. If it runs into something that it can’t parse then it throws a FormatException or if the number is too large an OverflowException. Also, it can throw an ArgumentException if you pass it a null value.

TryParse is a new addition to the new .Net 2.0 framework that addresses some issues with the original Parse function. The main difference is that exception handling is very slow, so if TryParse is unable to parse the string it does not throw an exception like Parse does. Instead, it returns a Boolean indicating if it was able to successfully parse a number. So you have to pass into TryParse both the string to be parsed and an Int32 out parameter to fill in. We will use the profiler to examine the speed difference between TryParse and Parse in both cases where the string can be correctly parsed and in cases where the string cannot be correctly parsed.

The Convert class contains a series of functions to convert one base class into another. I believe that Convert.ToInt32(string) just checks for a null string (if the string is null it returns zero unlike the Parse) then just calls Int32.Parse(string). I’ll use the profiler to confirm this and to see if using Convert as opposed to Parse has any real effect on performance.

The short answer is for creating an attribute in c# you only need to inherit it from Attribute class, Just this :)

But here I'm going to explain attributes in detail:

basically attributes are classes that we can use them for applying our logic to assemblies, classes, methods, properties, fields, ...

In .Net, Microsoft has provided some predefined Attributes like Obsolete or Validation Attributes like ( [Required], [StringLength(100)], [Range(0, 999.99)]), also we have kind of attributes like ActionFilters in asp.net that can be very useful for applying our desired logic to our codes (read this article about action filters if you are passionate to learn it)

one another point, you can apply a kind of configuration on your attribute via AttibuteUsage.

  [AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct, AllowMultiple = true)]

When you decorate an attribute class with AttributeUsage you can tell to c# compiler where I'm going to use this attribute: I'm going to use this on classes, on assemblies on properties or on ... and my attribute is allowed to use several times on defined targets(classes, assemblies, properties,...) or not?!

After this definition about attributes I'm going to show you an example: Imagine we want to define a new lesson in university and we want to allow just admins and masters in our university to define a new Lesson, Ok?

namespace ConsoleApp1

    /// <summary>

    [AttributeUsage(AttributeTargets.Class | AttributeTargets.Struct, AllowMultiple = true)]
    public class ValidRoleForAccess : Attribute
    {
        public ValidRoleForAccess(UniversityRoles role)
        {
            Role = role;
        }
        public UniversityRoles Role { get; private set; }

    }


    /// <summary>

            var lessType = typeof(Lesson);
            var validRolesForAccesses = lessType.GetCustomAttributes<ValidRoleForAccess>();

            if (validRolesForAccesses.All(x => x.Role.ToString() != owner.GetType().Name))
            {
                throw new Exception("You are not Allowed to define a new lesson");
            }

In the real world of programming maybe we don't use this approach for using attributes and I said this because of its educational point in using attributes

This recent June 2013 post goes into some detail into explaining the transition from relationship databases to objects with associations for some data types.

https://www.facebook.com/notes/facebook-engineering/tao-the-power-of-the-graph/10151525983993920

There's a longer paper available at https://www.usenix.org/conference/atc13/tao-facebook’s-distributed-data-store-social-graph

Nowadays, animating text color is included in the jQuery UI Effects Core. It's pretty small. You can make a custom download here: http://jqueryui.com/download - but you don't actually need anything but the effects core itself (not even the UI core), and it brings with it different easing functions as well.

Awesome answers I found here and I also tried this return statement see StatusCode(whatever code you wish) and it worked!!!

return Ok(new {
                    Token = new JwtSecurityTokenHandler().WriteToken(token),
                    Expiration = token.ValidTo,
                    username = user.FullName,
                    StatusCode = StatusCode(200)
                });

I had to figure it out myself but some svgs your need to match the viewBox & width+height in.

E.g. if it already has width="x" height="y" then =>

add <svg ... viewBox="0 0 [width] [height]">

and the opposite.

After that it will scale with <svg ... style="width: xxx; height: yyy;">

You should install IIS sub components from

Control Panel -> Programs and Features -> Turn Windows features on or off

Internet Information Services has subsection World Wide Web Services / Application Development Features

There you must check ASP.NET (.NET Extensibility, ISAPI Extensions, ISAPI Filters will be selected automatically). Double check that specific versions are checked. Under Windows Server 2012 R2, these options are split into 4 & 4.5.

Run from cmd:

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

Finally check in IIS manager, that your application uses application pool with .NET framework version v4.0.

Also, look at this answer.

Answer given by kennyut/Kistian works very well but to get exact RDD like output when RDD consist of list of attributes e.g. [1,2,3,4] we can use flatmap command as below,

rdd = df.rdd.flatMap(list)
or 
rdd = df.rdd.flatmap(lambda x: list(x))

Kay!

First of all, when dealing with strings you have to refer to their positions in 0 base convention. This means that if you have a string like this:

String str = "hi";
//str length is equal 2 but the character
//'h' is in the position 0 and character 'i' is in the postion 1

With that in mind, the best way to tackle this problem is creating a method to replace a character at a given position in a string like this:

Method:

public String changeCharInPosition(int position, char ch, String str){
    char[] charArray = str.toCharArray();
    charArray[position] = ch;
    return new String(charArray);
}

Then you should call the method 'changeCharInPosition' in this way:

String str = "hi";
str = changeCharInPosition(1, 'k', str);
System.out.print(str); //this will return "hk"

If you have any questions, don't hesitate, post something!

I believe you can use a case statement in a where clause, here is how I do it:

Select 
ProductID
OrderNo,
OrderType,
OrderLineNo
From Order_Detail
Where ProductID in (
Select Case when (@Varibale1 != '') 
then (Select ProductID from Product P Where .......)
Else (Select ProductID from Product)
End as ProductID
)

This method has worked for me time and again. try it!

Trying to fix this answer in How do I convert array of Objects into one Object in JavaScript?,

this should do it:

var array = [_x000D_
    {key:'k1',value:'v1'},_x000D_
    {key:'k2',value:'v2'},_x000D_
    {key:'k3',value:'v3'}_x000D_
];_x000D_
var mapped = array .map(item => ({ [item.key]: item.value }) );_x000D_
var newObj = Object.assign({}, ...mapped );_x000D_
console.log(newObj );

var newObj = Object.assign({}, ...(array.map(item => ({ [item.key]: item.value }) )));

You have a scalar valued function as opposed to a table valued function. The from clause is used for tables. Just query the value directly in the column list.

select dbo.fun_functional_score('01091400003')

It looks like you read twice, the read inside the while loop is not needed. Also, you don't need to invoke the cat command:

while read input
do
    echo $input
done < filename

Your second way is correct.

def foo(opts: dict = {}):
    pass

print(foo.__annotations__)

this outputs

{'opts': <class 'dict'>}

It's true that's it's not listed in PEP 484, but type hints are an application of function annotations, which are documented in PEP 3107. The syntax section makes it clear that keyword arguments works with function annotations in this way.

I strongly advise against using mutable keyword arguments. More information here.

In kotlin there is no replaceAll, so I created this loop to replace repeated values ??in a string or any variable.

 var someValue = "https://www.google.com.br/"
    while (someValue.contains(".")) {
        someValue = someValue.replace(".", "")
    }
Log.d("newValue :", someValue)
// in that case the stitches have been removed
//https://wwwgooglecombr/

With mailx you can do:

mailx -s "My Subject"  -a ./mail_att.csv -S [email protected]  [email protected] < ./mail_body.txt

This worked great on our GNU Linux servers, but unfortunately my dev environment is Mac OsX which only has a crummy old BSD version of mailx. Normally I use Coreutils to get better versions of unix commands than the Mac BSD ones, but mailx is not in Coreutils.

I found a solution from notpeter in an unrelated thread (https://serverfault.com/questions/196001/using-unix-mail-mailx-with-a-modern-mail-server-imap-instead-of-mbox-files) which was to download the Heirloom mailx OSX binary package from http://www.tramm.li/iWiki/HeirloomNotes.html. It has a more featured mailx which can handle the above command syntax.

What is -[NSString sizeWithFont:forWidth:lineBreakMode:] good for?

this question might have your answer, it worked for me.

For 2014, I edited in this new version, based on the ultra-handy comment by Norbert below! This does everything. Cheers

// yourLabel is your UILabel.

float widthIs = 
 [self.yourLabel.text
  boundingRectWithSize:self.yourLabel.frame.size                                           
  options:NSStringDrawingUsesLineFragmentOrigin
  attributes:@{ NSFontAttributeName:self.yourLabel.font }
  context:nil]
   .size.width;

NSLog(@"the width of yourLabel is %f", widthIs);

From the terminal run

jupyter nbconvert --execute --to notebook --inplace --allow-errors --ExecutePreprocessor.timeout=-1 my_nb.ipynb

The default timeout is 30 seconds. -1 removes the restriction.

If you wish to save the output notebook to a new notebook you can use the flag --output my_new_nb.ipynb

In case you need to parse it from a file, I find the best solution to use a HashMap<String, String> to use it inside your java code for better manipultion.

Try out this code:

public HashMap<String, String> myMethodName() throws FileNotFoundException
{
    String path = "absolute path to your file";
    BufferedReader bufferedReader = new BufferedReader(new FileReader(path));

    Gson gson = new Gson();
    HashMap<String, String> json = gson.fromJson(bufferedReader, HashMap.class);
    return json;
}

Sublime Text 2 & 3

The Comments of @crates work for me,

Step 1: Simply press on ctrl+H

Step 2: press on RegEX key

Step 3: write this in the Find: ^[\s]*?[\n\r]+

Step 4: replace all

1) Direct Answer: Try this:

   sudo updatedb
   locate OpenCVConfig.cmake

For me, I get:

   /home/pkarasev3/source/opencv/build/OpenCVConfig.cmake

To see the version, you can try:

   cat /home/pkarasev3/source/opencv/build/OpenCVConfig.cmake

giving

    ....
   SET(OpenCV_VERSION 2.3.1)
    ....

2) Better Answer:

"sudo make install" is your enemy, don't do that when you need to compile/update the library often and possibly debug step through it's internal functions. Notice how my config file is in a local build directory, not in /usr/something. You will avoid this confusion in the future, and can maintain several different versions even (debug and release, for example).

Edit: the reason this questions seems to arise often for OpenCV as opposed to other libraries is that it changes rather dramatically and fast between versions, and many of the operations are not so well-defined / well-constrained so you can't just rely on it to be a black-box like you do for something like libpng or libjpeg. Thus, better to not install it at all really, but just compile and link to the build folder.

It should be :

public async Task<ActionResult> GetSomeJsonData()
{
    var model = // ... get data or build model etc.

    return Json(new { Data = model }, JsonRequestBehavior.AllowGet); 
}

or more simply:

return Json(model, JsonRequestBehavior.AllowGet); 

I did notice that you are calling GetResources() from another ActionResult which wont work. If you are looking to get JSON back, you should be calling GetResources() from ajax directly...

if you want to always use git log in such way you could add git alias by

git config --global alias.log log --oneline

after that git log will print what normally would be printed by git log --oneline

As per the docs, OkHttp version 3 replaced FormEncodingBuilder with FormBody and FormBody.Builder(), so the old examples won't work anymore.

Form and Multipart bodies are now modeled. We've replaced the opaque FormEncodingBuilder with the more powerful FormBody and FormBody.Builder combo.

Similarly we've upgraded MultipartBuilder into MultipartBody, MultipartBody.Part, and MultipartBody.Builder.

So if you're using OkHttp 3.x try the following example:

OkHttpClient client = new OkHttpClient();

RequestBody formBody = new FormBody.Builder()
        .add("message", "Your message")
        .build();
Request request = new Request.Builder()
        .url("http://www.foo.bar/index.php")
        .post(formBody)
        .build();

try {
    Response response = client.newCall(request).execute();

    // Do something with the response.
} catch (IOException e) {
    e.printStackTrace();
}

Should I use(or both) for signing apk for play store release? An answer is YES.

As per https://source.android.com/security/apksigning/v2.html#verification :

In Android 7.0, APKs can be verified according to the APK Signature Scheme v2 (v2 scheme) or JAR signing (v1 scheme). Older platforms ignore v2 signatures and only verify v1 signatures.

I tried to generate build with checking V2(Full Apk Signature) option. Then when I tried to install a release build in below 7.0 device and I am unable to install build in the device.

After that I tried to build by checking both version checkbox and generate release build. Then able to install build.

You can split the processing into a specified number of threads using an approach like this:

            api.my_operation(item)

I do get the same information while debugging. Though not while I am checking the stacktrace. Most probably you would have used the optimization flag I think. Check this link - something related.

Try compiling with -g3 remove any optimization flag. Then it might work. HTH!

@Neil's answer is one (perfectly valid!) way of doing it, but you can also simply call matplotlib.use('Agg') before importing matplotlib.pyplot, and then continue as normal.

E.g.

import matplotlib as mpl
mpl.use('Agg')
import matplotlib.pyplot as plt

fig = plt.figure()
ax = fig.add_subplot(111)
ax.plot(range(10))
fig.savefig('temp.png')

You don't have to use the Agg backend, as well. The pdf, ps, svg, agg, cairo, and gdk backends can all be used without an X-server. However, only the Agg backend will be built by default (I think?), so there's a good chance that the other backends may not be enabled on your particular install.

Alternately, you can just set the backend parameter in your .matplotlibrc file to automatically have matplotlib.pyplot use the given renderer.

I would use a negative lookahead for any character:

^(?![\s\S])

This can only match if the input is totally empty, because the character class will match any character, including any of the various newline characters.

Depending on the boost version libboost-system comes with the -mt suffix which should indicate the libraries multithreading capability.

So if -lboost_system cannot be found by the linker try -lboost_system-mt.

The VPATH lines are wrong, they should be

vpath %.c  src
vpath %.h  src

i.e. not capital and without the = . As it is now, it doesn't find the .h file and thinks it is a target to be made.

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

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

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

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

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

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

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

I checked the source code you provided on GitHub. There were several mistakes / typos in the configuration.

In CustomerDbConfig / OrderDbConfig you should refer to customerEntityManager and packages should point at existing packages:

@Configuration
@EnableJpaRepositories(
    entityManagerFactoryRef = "customerEntityManager",
    transactionManagerRef = "customerTransactionManager",
    basePackages = {"com.mm.boot.multidb.repository.customer"})
public class CustomerDbConfig {

The packages to scan in customerEntityManager and orderEntityManager were both not pointing at proper package:

em.setPackagesToScan("com.mm.boot.multidb.model.customer");

Also the injection of proper EntityManagerFactory did not work. It should be:

@Bean(name = "customerTransactionManager")
public PlatformTransactionManager transactionManager(EntityManagerFactory customerEntityManager){

}

The above was causing the issue and the exception. While providing the name in a @Bean method you are sure you get proper EMF injected.

The last thing I have done was to disable to automatic configuration of JpaRepositories:

@EnableAutoConfiguration(exclude = JpaRepositoriesAutoConfiguration.class)

And with all fixes the application starts as you probably expect!

I solved my issue using the following command :

conda install opencv

Could use vim to do this:

vim -u NONE +'1d' +'wq!' /tmp/test.txt

This should be faster, since vim won't read whole file when process.

Please try this

select substring('12:20:19.8470000',1,(CHARINDEX('.','12:20:19.8470000',1)-1))


(No column name)
12:20:19

I think you just have incorrect casing in the format string. According to the documentation this should work for you: MM/DD/YYYY

Here is the right way to do imports in Java.

import Dan.Vik;
class Kab
{
public static void main(String args[])
{
    Vik Sam = new Vik();
    Sam.disp();
}
}

You don't import methods in java. There is an advanced usage of static imports but basically you just import packages and classes. If the function you are importing is a static function you can do a static import, but I don't think you are looking for static imports here.

How about pass?

I have copied the relevant code below from This page. Hope this might help you.

$.ajax({
  xhr: function() {
    var xhr = new window.XMLHttpRequest();
    //Upload progress
    xhr.upload.addEventListener("progress", function(evt) {
      if (evt.lengthComputable) {
        var percentComplete = evt.loaded / evt.total;
        //Do something with upload progress
        console.log(percentComplete);
      }
    }, false);
    //Download progress
    xhr.addEventListener("progress", function(evt) {
      if (evt.lengthComputable) {
        var percentComplete = evt.loaded / evt.total;
        //Do something with download progress
        console.log(percentComplete);
      }
    }, false);
    return xhr;
  },
  type: 'POST',
  url: "/",
  data: {},
  success: function(data) {
    //Do something success-ish
  }
});

If you want exactly 40 spaces before the string then you should just do:

printf("                                        %s\n", myStr );

If that is too dirty, you can do (but it will be slower than manually typing the 40 spaces): printf("%40s%s", "", myStr );

If you want the string to be lined up at column 40 (that is, have up to 39 spaces proceeding it such that the right most character is in column 40) then do this: printf("%40s", myStr);

You can also put "up to" 40 spaces AfTER the string by doing: printf("%-40s", myStr);

int = 4 byte (fixed irrespective size of the architect) NSInteger = depend upon size of the architect(e.g. for 4 byte architect = 4 byte NSInteger size)

Another interessant possibility of format date. This screenshot belongs to Apple's App "News".

Here is the code:

let dateFormat1 = DateFormatter()
dateFormat1.dateFormat = "EEEE"
let stringDay = dateFormat1.string(from: Date())

let dateFormat2 = DateFormatter()
dateFormat2.dateFormat = "MMMM"
let stringMonth = dateFormat2.string(from: Date())

let dateFormat3 = DateFormatter()
dateFormat3.dateFormat = "dd"
let numDay = dateFormat3.string(from: Date())

let stringDate = String(format: "%@\n%@ %@", stringDay.uppercased(), stringMonth.uppercased(), numDay)

Nothing to add to alternative proposed by lorenzoliveto. It's just perfect.

let dateFormat = DateFormatter()
dateFormat.dateFormat = "EEEE\nMMMM dd"
let stringDate = dateFormat.string(from: Date()).uppercased()

width, height = map(int, input().split())
def rectanglePerimeter(width, height):
   return ((width + height)*2)
print(rectanglePerimeter(width, height))

Running it like this produces:

% echo "1 2" | test.py
6

I suspect IDLE is simply passing a single string to your script. The first input() is slurping the entire string. Notice what happens if you put some print statements in after the calls to input():

width = input()
print(width)
height = input()
print(height)

Running echo "1 2" | test.py produces

1 2
Traceback (most recent call last):
  File "/home/unutbu/pybin/test.py", line 5, in <module>
    height = input()
EOFError: EOF when reading a line

Notice the first print statement prints the entire string '1 2'. The second call to input() raises the EOFError (end-of-file error).

So a simple pipe such as the one I used only allows you to pass one string. Thus you can only call input() once. You must then process this string, split it on whitespace, and convert the string fragments to ints yourself. That is what

width, height = map(int, input().split())

does.

Note, there are other ways to pass input to your program. If you had run test.py in a terminal, then you could have typed 1 and 2 separately with no problem. Or, you could have written a program with pexpect to simulate a terminal, passing 1 and 2 programmatically. Or, you could use argparse to pass arguments on the command line, allowing you to call your program with

test.py 1 2

Check out Convert a string representation of a hex dump to a byte array using Java?

Disregarding encoding, etc. you can do new String (hexStringToByteArray("75546..."));

I will group the options based on output. Assume the following vector for all the examples.

v <- c('z', 'a','b','a','e')

For checking presence:

%in%

> 'a' %in% v
[1] TRUE

any()

> any('a'==v)
[1] TRUE

is.element()

> is.element('a', v)
[1] TRUE

For finding first occurance:

match()

> match('a', v)
[1] 2

For finding all occurances as vector of indices:

which()

> which('a' == v)
[1] 2 4

For finding all occurances as logical vector:

==

> 'a' == v
[1] FALSE  TRUE FALSE  TRUE FALSE

Edit: Removing grep() and grepl() from the list for reason mentioned in comments

You would need to use Javascript for this. You can set the style of the background-image for the body like so.

var body = document.getElementsByTagName('body')[0];
body.style.backgroundImage = 'url(http://localhost/background.png)';

Just make sure you replace the URL with the actual URL.

parse_cols is deprecated, use usecols instead

that is:

df = pd.read_excel(file_loc, index_col=None, na_values=['NA'], usecols = "A,C:AA")

After each case statement require break or goto statement even if it is a default case.

You can do something exactly similar with the request library, but this is sync using const https = require('https'); or const http = require('http');, which should come with node.

Here is an example,

const https = require('https');

const http_get1 = {
    host : 'www.googleapis.com',
    port : '443',
    path : '/youtube/v3/search?arg=1',
    method : 'GET',
    headers : {
        'Content-Type' : 'application/json'
    }
};

const http_get2 = {
host : 'www.googleapis.com',
    port : '443',
    path : '/youtube/v3/search?arg=2',
    method : 'GET',
    headers : {
        'Content-Type' : 'application/json'
    }
};

let data1 = '';
let data2 = '';

function master() {

    if(!data1)
        return;

    if(!data2)
        return;

    console.log(data1);
    console.log(data2);

}

const req1 = https.request(http_get1, (res) => {
    console.log(res.headers);

    res.on('data', (chunk) => {
        data1 += chunk;
    });

    res.on('end', () => {
        console.log('done');
        master();
    });
});


const req2 = https.request(http_get2, (res) => {
    console.log(res.headers);

    res.on('data', (chunk) => {
        data2 += chunk;
    });

    res.on('end', () => {
        console.log('done');
        master();
    });
});

req1.end();
req2.end();

If you just want a maximum length, use StringUtils.left! No if or ternary ?: needed.

int maxLength = 5;
StringUtils.left(string, maxLength);

Output:

      null -> null
        "" -> ""
       "a" -> "a"
"abcd1234" -> "abcd1"

Left Documentation

brew install android-sdk --cask 

Iterate over the views that could be the first responder and use - (BOOL)isFirstResponder to determine if they currently are.

I found the answer to use double and triple quotation marks unsatisfactory. I used a nested DO...LOOP to write an ASP segment of code. There are repeated quotation marks within the string. When I ran the code:

thestring = "<asp:RectangleHotSpot Bottom=""" & bottom & """ HotSpotMode=""PostBack"" Left="""& left & """    PostBackValue=""" &xx & "." & yy & """ Right=""" & right & """ Top=""" & top & """/>"

the output was: <`asp:RectangleHotSpot Bottom="28

 'Changing the code to the explicit chr() call worked:

thestring = "<asp:RectangleHotSpot Bottom=""" & bottom & chr(34) & " HotSpotMode=""PostBack"" Left="""& left & chr(34) & " PostBackValue=""" &xx & "." & yy & chr(34) & " Right=""" & right & chr(34) & " Top=""" & top & chr(34) &"/>"

The output:

<asp:RectangleHotSpot Bottom="28" HotSpotMode="PostBack" Left="0" PostBackValue="0.0" Right="29" Top="0"/>

Deleting the project specific settings files (Eclipse workspace/project folder/.settings/) from the project folder also will do. Obviously, we need to do a project clean and build after deleting.

$(selector).length && //Do something

My Method:

protected void processRequest(HttpServletRequest request, HttpServletResponse response)
        throws ServletException, IOException {

    try {
        String path = request.getRealPath("/WEB-INF/conf.properties");
        Properties p = new Properties();
        p.load(new FileInputStream(path));

        String StringConexion=p.getProperty("StringConexion");
        String User=p.getProperty("User");
        String Password=p.getProperty("Password");
    }
    catch(Exception e){
        String msg = "Excepcion " + e;
    }
}

$(document).on('click', 'selector', handler);

Where click is an event name, and handler is an event handler, like reference to a function or anonymous function function() {}

PS: if you know the particular node you're adding dynamic elements to - you could specify it instead of document.

"Preprocess" in R:

lines <- "www, rrr, 1,234, ttt \n rrr,zzz, 1,234,567,987, rrr"

Can use readLines on a textConnection. Then remove only the commas that are between digits:

gsub("([0-9]+)\\,([0-9])", "\\1\\2", lines)

## [1] "www, rrr, 1234, ttt \n rrr,zzz, 1234567987, rrr"

It's als useful to know but not directly relevant to this question that commas as decimal separators can be handled by read.csv2 (automagically) or read.table(with setting of the 'dec'-parameter).

Edit: Later I discovered how to use colClasses by designing a new class. See:

How to load df with 1000 separator in R as numeric class?

The Question and most of the Answers are out of date.

Yes, it is an old wives' tale that MyISAM is faster than InnoDB. notice the Question's date: 2008; it is now almost a decade later. InnoDB has made significant performance strides since then.

The dramatic graph was for the one case where MyISAM wins: COUNT(*) without a WHERE clause. But is that really what you spend your time doing?

If you run concurrency test, InnoDB is very likely to win, even against MEMORY.

If you do any writes while benchmarking SELECTs, MyISAM and MEMORY are likely to lose because of table-level locking.

In fact, Oracle is so sure that InnoDB is better that they have all but removed MyISAM from 8.0.

The Question was written early in the days of 5.1. Since then, these major versions were marked "General Availability":

• 2010: 5.5 (.8 in Dec.)
• 2013: 5.6 (.10 in Feb.)
• 2015: 5.7 (.9 in Oct.)
• 2018: 8.0 (.11 in Apr.)

Bottom line: Don't use MyISAM

With in-built Spark csv, you can get it done easily with new SparkSession object for Spark > 2.0.

val df = spark.
        read.
        option("inferSchema", "false").
        option("header","true").
        option("mode","DROPMALFORMED").
        option("delimiter", ";").
        schema(dataSchema).
        csv("/csv/file/dir/file.csv")
df.show()
df.printSchema()

There are various options you can set.

• header: whether your file includes header line at the top
• inferSchema: whether you want to infer schema automatically or not. Default is true. I always prefer to provide schema to ensure proper datatypes.
• mode: parsing mode, PERMISSIVE, DROPMALFORMED or FAILFAST
• delimiter: to specify delimiter, default is comma(',')

The message is actually pretty clear: something creates a ThreadLocal with value of type org.apache.axis.MessageContext - this is a great hint. It most likely means that Apache Axis framework forgot/failed to cleanup after itself. The same problem occurred for instance in Logback. You shouldn't bother much, but reporting a bug to Axis team might be a good idea.

Tomcat reports this error because the ThreadLocals are created per HTTP worker threads. Your application is undeployed but HTTP threads remain - and these ThreadLocals as well. This may lead to memory leaks (org.apache.axis.MessageContext can't be unloaded) and some issues when these threads are reused in the future.

For details see: http://wiki.apache.org/tomcat/MemoryLeakProtection

Then NumPy sum function takes an optional axis argument that specifies along which axis you would like the sum performed:

>>> a = numpy.arange(12).reshape(4,3)
>>> a.sum(0)
array([18, 22, 26])

Or, equivalently:

>>> numpy.sum(a, 0)
array([18, 22, 26])

Generics:

With Java generics, you don't actually get any of the execution efficiency that you get with .NET because when you compile a generic class in Java, the compiler takes away the type parameter and substitutes Object everywhere. For instance if you have a Foo<T> class the java compiler generates Byte Code as if it was Foo<Object>. This means casting and also boxing/unboxing will have to be done in the "background".

I've been playing with Java/C# for a while now and, in my opinion, the major difference at the language level are, as you pointed, delegates.

If you want to amend a huge number of classes which had no serialVersionUID set in the first place while maintain the compatibility with the old classes, tools like IntelliJ Idea, Eclipse fall short as they generate random numbers and does not work on a bunch of files in one go. I come up the following bash script(I'm sorry for Windows users, consider buy a Mac or convert to Linux) to make amending serialVersionUID issue with ease:

base_dir=$(pwd)                                                                  
src_dir=$base_dir/src/main/java                                                  
ic_api_cp=$base_dir/target/classes                                               

while read f                                                                     
do                                                                               
    clazz=${f//\//.}                                                             
    clazz=${clazz/%.java/}                                                       
    seruidstr=$(serialver -classpath $ic_api_cp $clazz | cut -d ':' -f 2 | sed -e 's/^\s\+//')
    perl -ni.bak -e "print $_; printf qq{%s\n}, q{    private $seruidstr} if /public class/" $src_dir/$f
done

you save the this script, say add_serialVersionUID.sh to you ~/bin. Then you run it in the root directory of your Maven or Gradle project like:

add_serialVersionUID.sh < myJavaToAmend.lst

This .lst includes the list of java files to add the serialVersionUID in the following format:

com/abc/ic/api/model/domain/item/BizOrderTransDO.java
com/abc/ic/api/model/domain/item/CardPassFeature.java
com/abc/ic/api/model/domain/item/CategoryFeature.java
com/abc/ic/api/model/domain/item/GoodsFeature.java
com/abc/ic/api/model/domain/item/ItemFeature.java
com/abc/ic/api/model/domain/item/ItemPicUrls.java
com/abc/ic/api/model/domain/item/ItemSkuDO.java
com/abc/ic/api/model/domain/serve/ServeCategoryFeature.java
com/abc/ic/api/model/domain/serve/ServeFeature.java
com/abc/ic/api/model/param/depot/DepotItemDTO.java
com/abc/ic/api/model/param/depot/DepotItemQueryDTO.java
com/abc/ic/api/model/param/depot/InDepotDTO.java
com/abc/ic/api/model/param/depot/OutDepotDTO.java

This script uses the JDK serialVer tool under hood. So make sure your $JAVA_HOME/bin is in the PATH.

The solution suggested

<system.webServer>
  <modules runAllManagedModulesForAllRequests="true" >
    <remove name="UrlRoutingModule"/>    
  </modules>
</system.webServer>

works, but can degrade performance and can even cause errors, because now all registered HTTP modules run on every request, not just managed requests (e.g. .aspx). This means modules will run on every .jpg .gif .css .html .pdf etc.

A more sensible solution is to include this in your web.config:

<system.webServer>
  <modules>
    <remove name="UrlRoutingModule-4.0" />
    <add name="UrlRoutingModule-4.0" type="System.Web.Routing.UrlRoutingModule" preCondition="" />
  </modules>
</system.webServer>

if you want UTC try some of the gm functions:

import time
import calendar

date_time = '29.08.2011 11:05:02'
pattern = '%d.%m.%Y %H:%M:%S'
utc_epoch = calendar.timegm(time.strptime(date_time, pattern))
print utc_epoch

I will say no.

But the only proof that I have is personal experience and the fact that documentation on line continuation doesn't have anything else in it.

The below code helps me to return a JSON object for JavaScript on the front end

My template code

template_file.json

{
    "name": "{{name}}"
}

Python backed code

def download_json(request):
    print("Downloading JSON")
    # Response render a template as JSON object
    return HttpResponse(render_to_response("template_file.json",dict(name="Alex Vera")),content_type="application/json")    

File url.py

url(r'^download_as_json/$', views.download_json, name='download_json-url')

jQuery code for the front end

  $.ajax({
        url:'{% url 'download_json-url' %}'        
    }).done(function(data){
        console.log('json ', data);
        console.log('Name', data.name);
        alert('hello ' + data.name);
    });

My solution:

Try to find if this is an inodes problem with:

df -ih

Try to find root folders with large inodes count:

for i in /*; do echo $i; find $i |wc -l; done

Try to find specific folders:

for i in /src/*; do echo $i; find $i |wc -l; done

If this is linux headers, try to remove oldest with:

sudo apt-get autoremove linux-headers-3.13.0-24

Personally I moved them to a mounted folder (because for me last command failed) and installed the latest with:

sudo apt-get autoremove -f

This solved my problem.

        dataListAdapter() {

            Detail = null;

        }

        public View getView(int position, View convertView, ViewGroup parent) {

            LayoutInflater inflater = getLayoutInflater();
            View row;
            row = inflater.inflate(R.layout.custom, parent, false);
            TextView title, detail;
            ImageView i1;
            title = (TextView) row.findViewById(R.id.title);
            detail = (TextView) row.findViewById(R.id.detail);
            i1=(ImageView)row.findViewById(R.id.img);
            title.setText(Title[position]);
            detail.setText(Detail[position]);
            i1.setImageResource(imge[position]);

            return (row);
        }
    }
}

Try this.

Just add this class in your css

.column p{
   text-align:center;
}

It really depends on where your JavaScript code is located.

The problem is probably caused by the DOM not being loaded when the line

var systemStatus = document.getElementById("system-status");

is executed. You could try calling this in an onload event, or ideally use a DOM ready type event from a JavaScript framework.

When they say "The bottom of the page" they don't literally mean the bottom: they mean just before the closing </body> tag. Place your scripts there and they will be loaded before the DOMReady event; place them afterwards and the DOM will be ready before they are loaded (because it's complete when the closing </html> tag is parsed), which as you have found will not work.

If you're wondering how I know that this is what they mean: I have worked at Yahoo! and we put our scripts just before the </body> tag :-)

EDIT: also, see T.J. Crowder's reply and make sure you have things in the correct order.

I know it is an old post, but here is another simple solution that is fast.

Public Function worksheetExists(ByVal wb As Workbook, ByVal sheetNameStr As String) As Boolean

On Error Resume Next
worksheetExists = (wb.Worksheets(sheetNameStr).Name <> "")
Err.Clear: On Error GoTo 0

End Function

Check following link:

http://download.oracle.com/javase/1.5.0/docs/api/java/lang/System.html

You will clearly see that:

System is a class in the java.lang package.

out is a static member of the System class, and is an instance of java.io.PrintStream.

println is a method of java.io.PrintStream. This method is overloaded to print message to output destination, which is typically a console or file.

Fast method : (new foobar())->foobarfunc();

You need to load your class replace :

foobar::foobarfunc();

by :

(new foobar())->foobarfunc();

or :

$Foobar = new foobar();
$Foobar->foobarfunc();

Or make static function to use foobar::.

class foobar {
    //...

    static function foobarfunc() {
        return $this->foo();
    }
}

If you already unset the proxy from global and local level and still see the proxy details while you do

         git config -l

then unset the variable from system level, generally the configuration stored at below location

 C:\Program Files\Git\mingw64/etc/gitconfig

Not a single answer here actually answers the question. The OP did not ask about a singleton/per-application DbContext design, he asked about a per-(web)request design and what potential benefits could exist.

I'll reference http://mehdi.me/ambient-dbcontext-in-ef6/ as Mehdi is a fantastic resource:

Possible performance gains.

Each DbContext instance maintains a first-level cache of all the entities its loads from the database. Whenever you query an entity by its primary key, the DbContext will first attempt to retrieve it from its first-level cache before defaulting to querying it from the database. Depending on your data query pattern, re-using the same DbContext across multiple sequential business transactions may result in a fewer database queries being made thanks to the DbContext first-level cache.

It enables lazy-loading.

If your services return persistent entities (as opposed to returning view models or other sorts of DTOs) and you'd like to take advantage of lazy-loading on those entities, the lifetime of the DbContext instance from which those entities were retrieved must extend beyond the scope of the business transaction. If the service method disposed the DbContext instance it used before returning, any attempt to lazy-load properties on the returned entities would fail (whether or not using lazy-loading is a good idea is a different debate altogether which we won't get into here). In our web application example, lazy-loading would typically be used in controller action methods on entities returned by a separate service layer. In that case, the DbContext instance that was used by the service method to load these entities would need to remain alive for the duration of the web request (or at the very least until the action method has completed).

Keep in mind there are cons as well. That link contains many other resources to read on the subject.

Just posting this in case someone else stumbles upon this question and doesn't get absorbed in answers that don't actually address the question.

It is defenetly not a appropriate answer, but it is a small hint.

If you want to make use of static files in your App. You should put them as resources or as assets. But, if U have memory concerns like to keep your APK small, then you need to change your App design in such a way that,

instead of putting them as resources, while running your App(after installation) you can take the files(defenately different files as user may not keep files what you need) from SD Card. For this U can use ContentResolver to take audio, Image files on user selection.

With this you can give the user another feature like he can load audio/image files to the app on his own choice.

Since PostgreSQL 9.1 there is the convenient FOREACH:

DO
$do$
DECLARE
   m   varchar[];
   arr varchar[] := array[['key1','val1'],['key2','val2']];
BEGIN
   FOREACH m SLICE 1 IN ARRAY arr
   LOOP
      RAISE NOTICE 'another_func(%,%)',m[1], m[2];
   END LOOP;
END
$do$

Solution for older versions:

DO
$do$
DECLARE
   arr varchar[] := '{{key1,val1},{key2,val2}}';
BEGIN
   FOR i IN array_lower(arr, 1) .. array_upper(arr, 1)
   LOOP
      RAISE NOTICE 'another_func(%,%)',arr[i][1], arr[i][2];
   END LOOP;
END
$do$

Also, there is no difference between varchar[] and varchar[][] for the PostgreSQL type system. I explain in more detail here.

The DO statement requires at least PostgreSQL 9.0, and LANGUAGE plpgsql is the default (so you can omit the declaration).

Below is a batch file that will wait for 1 minute, check the day, and then perform an action. It uses PING.EXE, but requires no files that aren't included with Windows.

@ECHO OFF

:LOOP
ECHO Waiting for 1 minute...
  PING -n 60 127.0.0.1>nul
  IF %DATE:~0,3%==Mon CALL SomeOtherFile.cmd
  IF %DATE:~0,3%==Tue CALL SomeOtherFile.cmd
  IF %DATE:~0,3%==Wed CALL SomeOtherFile.cmd
  IF %DATE:~0,3%==Thu CALL WootSomeOtherFile.cmd
  IF %DATE:~0,3%==Fri CALL SomeOtherFile.cmd
  IF %DATE:~0,3%==Sat ECHO Saturday...nothing to do.
  IF %DATE:~0,3%==Sun ECHO Sunday...nothing to do.
GOTO LOOP

It could be improved upon in many ways, but it might get you started.

i think this can achieve what you want.

 Editable etext = mSubjectTextEditor.getText();
 Selection.setSelection(etext, etext.length());

If you do overflow:hidden then keep in mind that it will also hide the comment box that comes up in XFBML version... after user likes it. So best if you do this...

/* make the like button smaller */
.fb_edge_widget_with_comment iframe
{
    width:47px !important;
}

/* but make the span that holds the comment box larger */
span.fb_edge_comment_widget.fb_iframe_widget iframe
{
    width:401px !important;
}

If you don't want to do this in a batch script, you can do this from the command line like this:

for %I in (test.jpg) do @echo %~zI

Ugly, but it works. You can also pass in a file mask to get a listing for more than one file:

for %I in (*.doc) do @echo %~znI

Will display the size, file name of each .DOC file.

The keepNA = TRUE option prevents problems with NA

nchar(NA)
## [1] 2
nchar(NA, keepNA=TRUE)
## [1] NA

We can sort the list in one of two ways:

1. Using Comparator : When required to use the sort logic in multiple places If you want to use the sorting logic in a single place, then you can write an anonymous inner class as follows, or else extract the comparator and use it in multiple places

  Collections.sort(arrayList, new Comparator<ActiveAlarm>() {
        public int compare(ActiveAlarm o1, ActiveAlarm o2) {
            //Sorts by 'TimeStarted' property
            return o1.getTimeStarted()<o2.getTimeStarted()?-1:o1.getTimeStarted()>o2.getTimeStarted()?1:doSecodaryOrderSort(o1,o2);
        }

        //If 'TimeStarted' property is equal sorts by 'TimeEnded' property
        public int doSecodaryOrderSort(ActiveAlarm o1,ActiveAlarm o2) {
            return o1.getTimeEnded()<o2.getTimeEnded()?-1:o1.getTimeEnded()>o2.getTimeEnded()?1:0;
        }
    });

We can have null check for the properties, if we could have used 'Long' instead of 'long'.

2. Using Comparable(natural ordering): If sort algorithm always stick to one property: write a class that implements 'Comparable' and override 'compareTo' method as defined below

class ActiveAlarm implements Comparable<ActiveAlarm>{

public long timeStarted;
public long timeEnded;
private String name = "";
private String description = "";
private String event;
private boolean live = false;

public ActiveAlarm(long timeStarted,long timeEnded) {
    this.timeStarted=timeStarted;
    this.timeEnded=timeEnded;
}

public long getTimeStarted() {
    return timeStarted;
}

public long getTimeEnded() {
    return timeEnded;
}

public int compareTo(ActiveAlarm o) {
    return timeStarted<o.getTimeStarted()?-1:timeStarted>o.getTimeStarted()?1:doSecodaryOrderSort(o);
}

public int doSecodaryOrderSort(ActiveAlarm o) {
    return timeEnded<o.getTimeEnded()?-1:timeEnded>o.getTimeEnded()?1:0;
}

}

call sort method to sort based on natural ordering

Collections.sort(list);

Right now you're setting the innerHTML to an entire div element; you want to set it to just the innerHTML. Also, I think you want MyDiv2.innerHTML = MyDiv 1 .innerHTML. Also, I think the argument to document.getElementById is case sensitive. You were passing Div2 when you wanted DIV2

var MyDiv1 = Document.getElementById('DIV1');
var MyDiv2 = Document.getElementById('DIV2');
MyDiv2.innerHTML = MyDiv1.innerHTML; 

Also, this code will run before your DOM is ready. You can either put this script at the bottom of your body like paislee said, or put it in your body's onload function

<body onload="loadFunction()">

and then

function loadFunction(){
    var MyDiv1 = Document.getElementById('DIV1');
    var MyDiv2 = Document.getElementById('DIV2');
    MyDiv2.innerHTML = MyDiv1.innerHTML; 
}

Simplest way I could think of: add a class.

Simply add a class (on any element) and check inside the interval if it's there. This is more reliable, customisable and cross-language than any other way, I believe.

var i = 0;_x000D_
this.setInterval(function() {_x000D_
  if(!$('#counter').hasClass('pauseInterval')) { //only run if it hasn't got this class 'pauseInterval'_x000D_
    console.log('Counting...');_x000D_
    $('#counter').html(i++); //just for explaining and showing_x000D_
  } else {_x000D_
    console.log('Stopped counting');_x000D_
  }_x000D_
}, 500);_x000D_
_x000D_
/* In this example, I'm adding a class on mouseover and remove it again on mouseleave. You can of course do pretty much whatever you like */_x000D_
$('#counter').hover(function() { //mouse enter_x000D_
    $(this).addClass('pauseInterval');_x000D_
  },function() { //mouse leave_x000D_
    $(this).removeClass('pauseInterval');_x000D_
  }_x000D_
);_x000D_
_x000D_
/* Other example */_x000D_
$('#pauseInterval').click(function() {_x000D_
  $('#counter').toggleClass('pauseInterval');_x000D_
});

body {_x000D_
  background-color: #eee;_x000D_
  font-family: Calibri, Arial, sans-serif;_x000D_
}_x000D_
#counter {_x000D_
  width: 50%;_x000D_
  background: #ddd;_x000D_
  border: 2px solid #009afd;_x000D_
  border-radius: 5px;_x000D_
  padding: 5px;_x000D_
  text-align: center;_x000D_
  transition: .3s;_x000D_
  margin: 0 auto;_x000D_
}_x000D_
#counter.pauseInterval {_x000D_
  border-color: red;  _x000D_
}

<!-- you'll need jQuery for this. If you really want a vanilla version, ask -->_x000D_
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
_x000D_
_x000D_
<p id="counter">&nbsp;</p>_x000D_
<button id="pauseInterval">Pause/unpause</button></p>

Although this is valid in HTML, you can't use an ID starting with an integer in CSS selectors.

As pointed out, you can use getElementById instead, but you can also still achieve the same with a querySelector:

document.querySelector("[id='22']")

Needed to add - <meta http-equiv="X-UA-Compatible" content="IE=edge">

I was using Bootstrap 3 - had it working on IE on my local.

I put it live didn't work in IE.

Just Bootstrap doesn't include that line of code in their templates, I'm not sure why but it might be due to it not being W3C compatible.

The above didn't actually work for me as I had expected with Visual Studio 2010. It wouldn't let me access Properties.Resources, said it was inaccessible due to permission issues. I ultimately had to change the Persistence settings in the properties of the resource and then I found how to access it via the Resources.Designer.cs file, where it had an automatic getter that let me access the icon, via MyNamespace.Properties.Resources.NameFromAddingTheResource. That returns an object of type Icon, ready to just use.

putting a quick example, should be a sufficient starting point

Code in Form A

public event EventHandler<EventArgs> RowAdded;

private void btnRowAdded_Click(object sender, EventArgs e)
{
     // insert data
     // if successful raise event
     OnRowAddedEvent();
}

private void OnRowAddedEvent()
{
     var listener = RowAdded;
     if (listener != null)
         listener(this, EventArgs.Empty);
}

Code in Form B

private void button1_Click(object sender, EventArgs e)
{
     var frm = new Form2();
     frm.RowAdded += new EventHandler<EventArgs>(frm_RowAdded);
     frm.Show();
}

void frm_RowAdded(object sender, EventArgs e)
{
     // retrieve data again
}

You can even consider creating your own EventArgs class that can contain the newly added data. You can then use this to directly add the data to a new row in DatagridView

I don't think there is a way to ignore adding DEFINERs to the dump. But there are ways to remove them after the dump file is created.

1. Open the dump file in a text editor and replace all occurrences of DEFINER=root@localhost with an empty string ""

2. Edit the dump (or pipe the output) using perl:

   perl -p -i.bak -e "s/DEFINER=\`\w.*\`@\`\d[0-3].*[0-3]\`//g" mydatabase.sql
   

3. Pipe the output through sed:

   mysqldump ... | sed -e 's/DEFINER[ ]*=[ ]*[^*]*\*/\*/' > triggers_backup.sql
   

1. See information about the SQL server

tsql -LH SERVER_IP_ADDRESS

locale is "C"
locale charset is "646"
ServerName TITAN
InstanceName MSSQLSERVER
IsClustered No
Version 8.00.194
tcp 1433
np \\TITAN\pipe\sql\query

2. Set your freetds.conf

tsql -C    
freetds.conf directory: /usr/local/etc

[TITAN]
host = SERVER_IP_ADDRESS
port = 1433
tds version = 7.2

3 Try

tsql -S TITAN -U user -P password

OR

 'dsn' => 'dblib:host=TITAN:1433;dbname=YOURDBNAME',

See also http://www.freetds.org/userguide/confirminstall.htm (Example 3-5.)

If you get message 20009, remember you haven't connected to the machine. It's a configuration or network issue, not a protocol failure. Verify the server is up, has the name and IP address FreeTDS is using, and is listening to the configured port.

TRY THIS:

Cast your VARCHAR value to DATETIME and add -30 for subtraction. Also, In sql-server the format Fri, 14 Nov 2014 23:03:35 GMT was not converted to DATETIME. Try substring for it:

SELECT DATEADD(dd, -30, 
       CAST(SUBSTRING ('Fri, 14 Nov 2014 23:03:35 GMT', 6, 21) 
       AS DATETIME))

cat foo.txt | strings -n 8 > bar.txt

will do the job.

You can use this method if you use a MySQL database:

include('sql_connect.php');
$result = mysql_query("SELECT * FROM users WHERE `id`!='".$user_id."'");
while ($row = mysql_fetch_array($result))
{
    if ($_GET['to'] == $row['id'])
    {
        $selected = 'selected="selected"';
    }
    else
    {
    $selected = '';
    }
    echo('<option value="'.$row['id'].' '.$selected.'">'.$row['username'].' ('.$row['fname'].' '.substr($row['lname'],0,1).'.)</option>');
}
mysql_close($con);

It will compare if the user in $_GET['to'] is the same as $row['id'] in table, if yes, the $selected will be created. This was for a private messaging system...

Google will eventually block your IP when you exceed a certain amount of requests.

In short, the answer is "Yes".

In Java, the == operator compares the two objects to see if they point to the same memory location; while the .equals() method actually compares the two objects to see if they have the same object value.

An alternative way, supporting decimals, different separators and negatives.

var number_format = function(number, decimal_pos, decimal_sep, thousand_sep) {
    var ts      = ( thousand_sep == null ? ',' : thousand_sep )
        , ds    = ( decimal_sep  == null ? '.' : decimal_sep )
        , dp    = ( decimal_pos  == null ? 2   : decimal_pos )

        , n     = Math.floor(Math.abs(number)).toString()

        , i     = n.length % 3 
        , f     = ((number < 0) ? '-' : '') + n.substr(0, i)
    ;

    for(;i<n.length;i+=3) {
        if(i!=0) f+=ts;
        f+=n.substr(i,3);
    }

    if(dp > 0) 
        f += ds + parseFloat(number).toFixed(dp).split('.')[1]

    return f;
}

Convert it to type Char?

You can try this FLAG_ACTIVITY_REORDER_TO_FRONT (the document describes exactly what you want to)

Here is another most easy way to get a custom shape for your image (Image View). It may be helpful for someone. It's just a single line code.

First you need to add a dependency:

dependencies {
    compile 'com.mafstech.libs:mafs-image-shape:1.0.4'   
}

And then just write a line of code like this:

Shaper.shape(context, 
       R.drawable.your_original_image_which_will_be_displayed, 
       R.drawable.shaped_image_your_original_image_will_get_this_images_shape,
       imageView,
       height, 
       weight);   

It only matter of taste.
Use whatever you wish.

Most of time I am using second one but it depends.

Let me suggest you also to get yourself a good editor which will highlight a variable inside of a string

One way to achieve this is to add a DefaultDocument settings in the Web.config.

  <system.webServer>
   <defaultDocument>
    <files>
      <clear />
      <add value="DefaultPage.aspx" />
    </files>
   </defaultDocument>
  </system.webServer>

for item in do_not_use_list_as_a_name[1:-1]:
    #...do whatever

I agree with user3158900, and I only differ slightly in the way I use it:

{{Form::label('sports', 'Sports')}}
{{Form::select('sports',$aSports,null,array('multiple'=>'multiple','name'=>'sports[]'))}}

However, in my experience the 3rd parameter of the select is a string only, so for repopulating data for a multi-select I have had to do something like this:

<select multiple="multiple" name="sports[]" id="sports">
@foreach($aSports as $aKey => $aSport)
    @foreach($aItem->sports as $aItemKey => $aItemSport)
        <option value="{{$aKey}}" @if($aKey == $aItemKey)selected="selected"@endif>{{$aSport}}</option>
    @endforeach
@endforeach
</select>

Identifiers (including column names) that are not double-quoted are folded to lower case in PostgreSQL. Column names that were created with double-quotes and thereby retained upper-case letters (and/or other syntax violations) have to be double-quoted for the rest of their life:

"first_Name"

Values (string literals / constants) are enclosed in single quotes:

'xyz'

So, yes, PostgreSQL column names are case-sensitive (when double-quoted):

SELECT * FROM persons WHERE "first_Name" = 'xyz';

Read the manual on identifiers here.

My standing advice is to use legal, lower-case names exclusively so double-quoting is not needed.

Easier solution will be changing this line

ft.replace(R.id.content_frame, A); to ft.add(R.id.content_frame, A);

And inside your XML layout please use

  android:background="@color/white"
  android:clickable="true"
  android:focusable="true"

Clickable means that it can be clicked by a pointer device or be tapped by a touch device.

Focusable means that it can gain the focus from an input device like a keyboard. Input devices like keyboards cannot decide which view to send its input events to based on the inputs itself, so they send them to the view that has focus.

I don't know how was the plugin the time the question was asked (2010), but I faced the same problem today and solved it this way:

1. Give your select tag a name attribute. For example in this case

   <select name="myselect">

2. Instead of working with the attribute value="default" in the tag option, disable the default option or set value="" as suggested by Andrew Coats

   <option disabled="disabled">Choose...</option>

   or

   <option value="">Choose...</option>

3. Set the plugin validation rule

   $( "#YOUR_FORM_ID" ).validate({ rules: { myselect: { required: true } } });

   or

   <select name="myselect" class="required">

Obs: Andrew Coats' solution works only if you have just one select in your form. If you want his solution to work with more than one select add a name attribute to your select.

Hope it helps! :)

Remember this if all your Strings in the column do not have an underscore (...or else if null value will be the output):

SELECT COALESCE
(SUBSTR("STRING_COLUMN" , 0, INSTR("STRING_COLUMN", '_')-1), 
"STRING_COLUMN") 
AS OUTPUT FROM DUAL

for window :

pip install mysqlclient pymysql

then:

import pymysql pymysql.install_as_MySQLdb()

for python 3 Ubuntu

sudo apt-get install -y python3-mysqldb

import platform
platform.architecture()

From the Python docs:

Queries the given executable (defaults to the Python interpreter binary) for various architecture information.

Returns a tuple (bits, linkage) which contain information about the bit architecture and the linkage format used for the executable. Both values are returned as strings.

4 spaces do the trick even inside definition list:

Endpoint
: `/listAgencies`

Method
: `GET`

Arguments
:   * `level` - bla-bla.
    * `withDisabled` - should we include disabled `AGENT`s.
    * `userId` - bla-bla.

I am documenting API using BitBucket Wiki and Markdown proprietary extension for definition list is most pleasing (MD's table syntax is awful, imaging multiline and embedding requirements...).

Here is my two cents:

int split (const char *txt, char delim, char ***tokens)
{
    int *tklen, *t, count = 1;
    char **arr, *p = (char *) txt;

    while (*p != '\0') if (*p++ == delim) count += 1;
    t = tklen = calloc (count, sizeof (int));
    for (p = (char *) txt; *p != '\0'; p++) *p == delim ? *t++ : (*t)++;
    *tokens = arr = malloc (count * sizeof (char *));
    t = tklen;
    p = *arr++ = calloc (*(t++) + 1, sizeof (char *));
    while (*txt != '\0')
    {
        if (*txt == delim)
        {
            p = *arr++ = calloc (*(t++) + 1, sizeof (char *));
            txt++;
        }
        else *p++ = *txt++;
    }
    free (tklen);
    return count;
}

Usage:

char **tokens;
int count, i;
const char *str = "JAN,FEB,MAR,APR,MAY,JUN,JUL,AUG,SEP,OCT,NOV,DEC";

count = split (str, ',', &tokens);
for (i = 0; i < count; i++) printf ("%s\n", tokens[i]);

/* freeing tokens */
for (i = 0; i < count; i++) free (tokens[i]);
free (tokens);

Gilean's answer is great, but I just wanted to add that sometimes there are rare exceptions to best practices, and you might want to test your environment both ways to see what will work best.

In one case, I found that query worked faster for my purposes because I was bulk transferring trusted data from an Ubuntu Linux box running PHP7 with the poorly supported Microsoft ODBC driver for MS SQL Server.

I arrived at this question because I had a long running script for an ETL that I was trying to squeeze for speed. It seemed intuitive to me that query could be faster than prepare & execute because it was calling only one function instead of two. The parameter binding operation provides excellent protection, but it might be expensive and possibly avoided if unnecessary.

Given a couple rare conditions:

1. If you can't reuse a prepared statement because it's not supported by the Microsoft ODBC driver.

2. If you're not worried about sanitizing input and simple escaping is acceptable. This may be the case because binding certain datatypes isn't supported by the Microsoft ODBC driver.

3. PDO::lastInsertId is not supported by the Microsoft ODBC driver.

Here's a method I used to test my environment, and hopefully you can replicate it or something better in yours:

To start, I've created a basic table in Microsoft SQL Server

CREATE TABLE performancetest (
    sid INT IDENTITY PRIMARY KEY,
    id INT,
    val VARCHAR(100)
);

And now a basic timed test for performance metrics.

$logs = [];

$test = function (String $type, Int $count = 3000) use ($pdo, &$logs) {
    $start = microtime(true);
    $i = 0;
    while ($i < $count) {
        $sql = "INSERT INTO performancetest (id, val) OUTPUT INSERTED.sid VALUES ($i,'value $i')";
        if ($type === 'query') {
            $smt = $pdo->query($sql);
        } else {
            $smt = $pdo->prepare($sql);
            $smt ->execute();
        }
        $sid = $smt->fetch(PDO::FETCH_ASSOC)['sid'];
        $i++;
    }
    $total = (microtime(true) - $start);
    $logs[$type] []= $total;
    echo "$total $type\n";
};

$trials = 15;
$i = 0;
while ($i < $trials) {
    if (random_int(0,1) === 0) {
        $test('query');
    } else {
        $test('prepare');
    }
    $i++;
}

foreach ($logs as $type => $log) {
    $total = 0;
    foreach ($log as $record) {
        $total += $record;
    }
    $count = count($log);
    echo "($count) $type Average: ".$total/$count.PHP_EOL;
}

I've played with multiple different trial and counts in my specific environment, and consistently get between 20-30% faster results with query than prepare/execute

5.8128969669342 prepare
5.8688418865204 prepare
4.2948560714722 query
4.9533629417419 query
5.9051351547241 prepare
4.332102060318 query
5.9672858715057 prepare
5.0667371749878 query
3.8260300159454 query
4.0791549682617 query
4.3775160312653 query
3.6910600662231 query
5.2708210945129 prepare
6.2671611309052 prepare
7.3791449069977 prepare
(7) prepare Average: 6.0673267160143
(8) query Average: 4.3276024162769

I'm curious to see how this test compares in other environments, like MySQL.

Ta da:

NSInteger myInteger = 42;
int myInt = (int) myInteger;

NSInteger is nothing more than a 32/64 bit int. (it will use the appropriate size based on what OS/platform you're running)

I believe that throwing an exception is a better idea for your situation. An alternative will be the simulation method to return a tuple. The first item will be the status and the second one the result:

result = simulate(open("myfile"))
if not result[0]:
  print "error parsing stream"
else:
  ret= result[1]

use this code

//print the vector element in reverse order by normal iterator.
cout <<"print the vector element in reverse order by normal iterator." <<endl;
vector<string>::iterator iter=vec.end();
--iter;
while (iter != vec.begin())
{
    cout << *iter  << " "; 
    --iter;
}

Here is a Hand Made Solution:

function iterationForObject() {
    let base = 0,
        Keys= Object.keys(this);
    return {
        next: () => {
            return {
                value: {
                    "key": Keys[base],
                    "value": this[Keys[base]]
                },
                done: !(base++ < Keys.length)
            };
        }
    };
}
Object.prototype[Symbol.iterator] = iterationForObject;

And Then You Can Loop Any Object:

for ( let keyAndValuePair of (Object Here) ) {
    console.log(`${keyAndValuePair.key} => ${keyAndValuePair.value}`);
}

The example code here http://msdn.microsoft.com/en-us/library/system.net.sockets.socket.connected.aspx shows how to determine whether the Socket is still connected without sending any data.

If you called Socket.BeginReceive() on the server program and then the client closed the connection "gracefully", your receive callback will be called and EndReceive() will return 0 bytes. These 0 bytes mean that the client "may" have disconnected. You can then use the technique shown in the MSDN example code to determine for sure whether the connection was closed.

int result= YourDictionaryName.TryGetValue(key, out int value) ? YourDictionaryName[key] : 0;

If the key is present in the dictionary, it returns the value of the key otherwise it returns 0.

Hope, this code helps you.

Building on some of the answers here and elsewhere, I've written this simple function which displays a progress bar and elapsed/estimated remaining time. Should work on most unix-based machines.

import time
import sys

percent = 50.0
start = time.time()
draw_progress_bar(percent, start)


def draw_progress_bar(percent, start, barLen=20):
sys.stdout.write("\r")
progress = ""
for i in range(barLen):
    if i < int(barLen * percent):
        progress += "="
    else:
        progress += " "

elapsedTime = time.time() - start;
estimatedRemaining = int(elapsedTime * (1.0/percent) - elapsedTime)

if (percent == 1.0):
    sys.stdout.write("[ %s ] %.1f%% Elapsed: %im %02is ETA: Done!\n" % 
        (progress, percent * 100, int(elapsedTime)/60, int(elapsedTime)%60))
    sys.stdout.flush()
    return
else:
    sys.stdout.write("[ %s ] %.1f%% Elapsed: %im %02is ETA: %im%02is " % 
        (progress, percent * 100, int(elapsedTime)/60, int(elapsedTime)%60,
         estimatedRemaining/60, estimatedRemaining%60))
    sys.stdout.flush()
    return

I think your problems are due to your test structure. I've found it difficult to mix mocking with the traditional method of implementing interfaces in the test class (as you've done here).

If you implement the listener as a Mock you can then verify the interaction.

Listener listener = mock(Listener.class);
w.addListener(listener);
world.doAction(..);
verify(listener).doAction();

This should satisfy you that the 'World' is doing the right thing.

I had the same problem after installing TensorFlow package, which downgraded my pandas version from 2.23 to 2.22. I tried all the solutions proposed above + the one suggested by post author, linked here. What eventually worked for me was to reinstall Anaconda distribution.

There are situations where you can't use the (quite convincing) with... for... structure. In that case, do the following:

line = self.fo.readline()
if len(line) != 0:
     if 'str' in line:
         break

This will work because the the readline() leaves a trailing newline character, where as EOF is just an empty string.

I have also used following link as others have suggested you for bluetooth communication.

http://developer.android.com/guide/topics/connectivity/bluetooth.html

The thing is all you need is a class BluetoothChatService.java

this class has following threads:

1. Accept
2. Connecting
3. Connected

Now when you call start function of the BluetoothChatService like:

mChatService.start();

It starts accept thread which means it will start looking for connection.

Now when you call

mChatService.connect(<deviceObject>,false/true);

Here first argument is device object that you can get from paired devices list or when you scan for devices you will get all the devices in range you can pass that object to this function and 2nd argument is a boolean to make secure or insecure connection.

connect function will start connecting thread which will look for any device which is running accept thread.

When such a device is found both accept thread and connecting thread will call connected function in BluetoothChatService:

connected(mmSocket, mmDevice, mSocketType);

this method starts connected thread in both the devices: Using this socket object connected thread obtains the input and output stream to the other device. And calls read function on inputstream in a while loop so that it's always trying read from other device so that whenever other device send a message this read function returns that message.

BluetoothChatService also has a write method which takes byte[] as input and calls write method on connected thread.

mChatService.write("your message".getByte());

write method in connected thread just write this byte data to outputsream of the other device.

public void write(byte[] buffer) {
   try {
       mmOutStream.write(buffer);
    // Share the sent message back to the UI Activity
    // mHandler.obtainMessage(
    // BluetoothGameSetupActivity.MESSAGE_WRITE, -1, -1,
    // buffer).sendToTarget();
    } catch (IOException e) {
    Log.e(TAG, "Exception during write", e);
     }
}

Now to communicate between two devices just call write function on mChatService and handle the message that you will receive on the other device.

Use:

#define convertToString(x) #x

int main()
{
    convertToString(42); // Returns const char* equivalent of 42
}

Use re.findall or re.finditer instead.

re.findall(pattern, string) returns a list of matching strings.

re.finditer(pattern, string) returns an iterator over MatchObject objects.

Example:

re.findall( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')
# Output: ['cats', 'dogs']

[x.group() for x in re.finditer( r'all (.*?) are', 'all cats are smarter than dogs, all dogs are dumber than cats')]
# Output: ['all cats are', 'all dogs are']

Try

$(document).ready(

instead of

$('document').ready(

or you can use a shorthand form

$(function(){
});

The encryption methods described are symmetric key block ciphers.

Data Encryption Standard (DES) is the predecessor, encrypting data in 64-bit blocks using a 56 bit key. Each block is encrypted in isolation, which is a security vulnerability.

Triple DES extends the key length of DES by applying three DES operations on each block: an encryption with key 0, a decryption with key 1 and an encryption with key 2. These keys may be related.

DES and 3DES are usually encountered when interfacing with legacy commercial products and services.

AES is considered the successor and modern standard. http://en.wikipedia.org/wiki/Advanced_Encryption_Standard

I believe the use of Blowfish is discouraged.

It is highly recommended that you do not attempt to implement your own cryptography and instead use a high-level implementation such as GPG for data at rest or SSL/TLS for data in transit. Here is an excellent and sobering video on encryption vulnerabilities http://rdist.root.org/2009/08/06/google-tech-talk-on-common-crypto-flaws/

Please note that IDEs like IntelliJ IDEA tend to start their own adb-server.

Even manually killing the server and running an new instance with sudo won't help here until you make your IDE kill the server itself.

It is a little late but it might help someone. I created a procedure sometimes back which does the following using T-SQL:

1. Store all constraints in a Temporary table
2. Drop All Constraints
3. Truncate all tables with exception of some tables, which does not need truncation
4. Recreate all Constraints.

I have listed it on my blog here

If you are running local using spring i'd suggest use:

@Bean
public AmazonDynamoDB amazonDynamoDB() throws IOException {
    return AmazonDynamoDBClientBuilder.standard()
            .withCredentials(
                    new AWSStaticCredentialsProvider(
                            new BasicAWSCredentials("fake", "credencial")
                    )
            )
            .withClientConfiguration(new ClientConfigurationFactory().getConfig().withProtocol(Protocol.HTTP))
            .withEndpointConfiguration(new AwsClientBuilder.EndpointConfiguration("localhost:8443", "central"))
            .build();
}

It works for me using unit test.

Hope it's help!

To remove .idea/ completely from the git without affecting your IDE config you could just do:

git rm -r --cached '.idea/'
echo .idea >> .gitignore
git commit -am "removed .idea/ directory"

echo $PATH

it prints current path value

Then do vim ~/.bash_profile and write

export PATH=$PATH:/new/path/to/be/added

here you are appending to the old path, so preserves the old path and adds your new path to it

then do

source ~/.bash_profile

this will execute it and add the path

then again check with

echo $PATH

Which loop are you trying to exit? A simple break; will exit the inner loop. For the outer loop, you could use an outer loop-scoped variable (e.g. boolean exit = false;) which is set to true just before you break your inner loop. After the inner loop block check the value of exit and if true use break; again.

    // Create the path (with only the top-left corner rounded)
UIBezierPath *maskPath = [UIBezierPath bezierPathWithRoundedRect:view.bounds 
                           byRoundingCorners:(UIRectCornerBottomLeft | UIRectCornerBottomRight) 
                           cornerRadii:CGSizeMake(7.0, 7.0)];

// Create the shape layer and set its path
CAShapeLayer *maskLayer = [CAShapeLayer layer];
maskLayer.frame = cell.stripBlackImnageView.bounds;
maskLayer.path = maskPath.CGPath; 
// Set the newly created shapelayer as the mask for the image view's layer
view.layer.mask = maskLayer;

In Angular we can add an option as placeholder that can be hidden in option dropdown. We can even add a custom dropdown icon as background that replaces browser dropdown icon.

The trick is to enable placeholder css only when value is not selected

/**My Component Template*/

 <div class="dropdown">
      <select [ngClass]="{'placeholder': !myForm.value.myField}"
 class="form-control" formControlName="myField">
        <option value="" hidden >Select a Gender</option>
        <option value="Male">Male</option>
        <option value="Female">Female</option>
      </select>
    </div>

/**My Component.TS */

constructor(fb: FormBuilder) {
  this.myForm = this.fb.build({
    myField: ''
  });
}

/**global.scss*/

.dropdown {
  width: 100%;
  height: 30px;
  overflow: hidden;
  background: no-repeat white;
  background-image:url('angle-arrow-down.svg');
  background-position: center right;
  select {
    background: transparent;
    padding: 3px;
    font-size: 1.2em;
    height: 30px;
    width: 100%;
    overflow: hidden;

    /*For moz*/
    -moz-appearance: none;
    /* IE10 */
    &::-ms-expand {
      display: none;
    }
    /*For chrome*/
    -webkit-appearance:none;
    &.placeholder {
      opacity: 0.7;
      color: theme-color('mutedColor');
    }
    option {
      color: black;
    }
  }
}

I had a similar issue and this is the first thread that came up when I Googled for an answer.

What I had to do was in project > properties, go to Java Build Path > Libraries > Modulepath and change JRE System Library from (in my case) JavaSE-14 (unbound) to JavaSE-11 (Java SE 11.0.2 [11.0.2]).

I think the JavaSE-14 may not have been installed or something because it said (unbound) but the rest of the versions had a longer Java version name and number within the parentheses

I hope it helps somebody.

You can add an conditional statement. If your array goes beyond index, then break and print the rest of the file.

Since none of the answers mentioned the upcoming Ranges library, which is available in the standard library since C++20, and currently separately available on GitHub as range-v3, I would like to add a way to perform this conversion using it.

To modify the string in-place:

str |= action::transform([](unsigned char c){ return std::tolower(c); });

To generate a new string:

auto new_string = original_string
    | view::transform([](unsigned char c){ return std::tolower(c); });

(Don't forget to #include <cctype> and the required Ranges headers.)

Note: the use of unsigned char as the argument to the lambda is inspired by cppreference, which states:

Like all other functions from <cctype>, the behavior of std::tolower is undefined if the argument's value is neither representable as unsigned char nor equal to EOF. To use these functions safely with plain chars (or signed chars), the argument should first be converted to unsigned char:

char my_tolower(char ch)
{
    return static_cast<char>(std::tolower(static_cast<unsigned char>(ch)));
}

Similarly, they should not be directly used with standard algorithms when the iterator's value type is char or signed char. Instead, convert the value to unsigned char first:

std::string str_tolower(std::string s) {
    std::transform(s.begin(), s.end(), s.begin(), 
                // static_cast<int(*)(int)>(std::tolower)         // wrong
                // [](int c){ return std::tolower(c); }           // wrong
                // [](char c){ return std::tolower(c); }          // wrong
                   [](unsigned char c){ return std::tolower(c); } // correct
                  );
    return s;
}

From the documentation

To create your own link with a pre-filled message that will automatically appear in the text field of a chat, use https://wa.me/whatsappphonenumber/?text=urlencodedtext where whatsappphonenumber is a full phone number in international format and URL-encodedtext is the URL-encoded pre-filled message.

Example:https://wa.me/15551234567?text=I'm%20interested%20in%20your%20car%20for%20sale

Code example

val phoneNumber = "13492838472"
    val text = "Hey, you know... I love StackOverflow :)"
    val uri = Uri.parse("https://wa.me/$phoneNumber/?text=$text")
    val sendIntent = Intent(Intent.ACTION_VIEW, uri)
    startActivity(sendIntent)

For some reason, none of the above worked for me. This DID however:

1. Selected the range of cells I needed to replace.
2. Go to Home > Find & Select > Replace or Ctrl + H
3. Find what: ,
4. Replace with: CTRL + SHIFT + J
5. Click Replace All

Somehow CTRL + SHIFT + J is registered as a linebreak.

You should use the StringBuilder class.

StringBuilder stringBuilder = new StringBuilder();

stringBuilder.append("Some text");
stringBuilder.append("Some text");
stringBuilder.append("Some text");

String finalString = stringBuilder.toString();

In addition, please visit:

• "How Java optimize the code with StringBuilder?"
• "StringBuilder vs String concatenation in toString() in Java"

The case statement is your friend in this situation, and takes one of two forms:

The simple case:

SELECT CASE <variable> WHEN <value>      THEN <returnvalue>
                       WHEN <othervalue> THEN <returnthis>
                                         ELSE <returndefaultcase>
       END AS <newcolumnname>
FROM <table>

The extended case:

SELECT CASE WHEN <test>      THEN <returnvalue>
            WHEN <othertest> THEN <returnthis>
                             ELSE <returndefaultcase>
       END AS <newcolumnname>
FROM <table>

You can even put case statements in an order by clause for really fancy ordering.

modified $.each function

$.fn.eachReturn = function(arr, callback) {
   var result = null;
   $.each(arr, function(index, value){
       var test = callback(index, value);
       if (test) {
           result = test;
           return false;
       }
   });
   return result ;
}

it will break loop on non-false/non-empty result and return it back, so in your case it would be

return $.eachReturn(someArray, function(i){
    ...

You can also just "not" add a url inside the <a> tag, i do this for menus that are <a> tag driven with drop downs as well. If there is not drop down then i add the url but if there are drop downs with a <ul> <li> list i just remove it.

What finally worked for me, and I have no idea why, is:

• Went to LastPass (the service I use to keep all my passwords)
• Select my password by putting the cursor on top of the password and double clicking
• Once selected I press cmd C to copy
• Went to Android study and cmd V to paste

Notice I did try to copy many times by selecting the password by clicking at the end of the password and selecting the password by moving the mouse.

It is strange but it only worked by double clicking on top of the password to copy it.

Also I did use the Open Module Settings > Signing... method explained by @NightFury on this post.

Looks it's one of the early asked question about Golang . And same time answers to never update . During these three to four years , too many new libraries and blog post has been out . Below are the few links what I felt useful .

SWIG and Go

Calling C++ Code From Go With SWIG

On comparing languages, C++ and Go

GoForCPPProgrammers

I got here with a similar problem with my Gradle build and fixed it in a similar way:

Unable to load class hudson.model.User due to missing dependency javax/servlet/ServletException

fixed with:

dependencies {
   implementation('javax.servlet:javax.servlet-api:3.0.1')
}

If all you want to know is if the browser is IE or not, you can do this:

var isIE = false;
var ua = window.navigator.userAgent;
var old_ie = ua.indexOf('MSIE ');
var new_ie = ua.indexOf('Trident/');

if ((old_ie > -1) || (new_ie > -1)) {
    isIE = true;
}

if ( isIE ) {
    //IE specific code goes here
}

Update 1: A better method

I recommend this now. It is still very readable and is far less code :)

var ua = window.navigator.userAgent;
var isIE = /MSIE|Trident/.test(ua);

if ( isIE ) {
  //IE specific code goes here
}

Thanks to JohnnyFun in the comments for the shortened answer :)

Update 2: Testing for IE in CSS

Firstly, if you can, you should use @supports statements instead of JS for checking if a browser supports a certain CSS feature.

.element {
  /* styles for all browsers */
}

@supports (display: grid) {
  .element {
    /* styles for browsers that support display: grid */
  }
}

(Note that IE doesn't support @supports at all and will ignore any styles placed inside an @supports statement.)

If the issue can't be resolved with @supports then you can do this:

// JS

var ua = window.navigator.userAgent;
var isIE = /MSIE|Trident/.test(ua);

if ( isIE ) {
  document.documentElement.classList.add('ie')
}

/* CSS */

.element {
  /* styles that apply everywhere */
}

.ie .element {
  /* styles that only apply in IE */
}

(Note: classList is relatively new to JS and I think, out of the IE browsers, it only works in IE11. Possibly also IE10.)

If you are using SCSS (Sass) in your project, this can be simplified to:

/* SCSS (Sass) */

.element {
  /* styles that apply everywhere */

  .ie & {
    /* styles that only apply in IE */
  }
}

Update 3: Adding Microsoft Edge (not recommended)

If you also want to add Microsoft Edge into the list, you can do the following. However I do not recommend it as Edge is a much more competent browser than IE.

var ua = window.navigator.userAgent;
var isIE = /MSIE|Trident|Edge\//.test(ua);

if ( isIE ) {
  //IE & Edge specific code goes here
}

My personal opinion is to use what makes sense in the context. Personally I almost never use for for array traversal. I use it for other types of iteration, but foreach is just too easy... The time difference is going to be minimal in most cases.

The big thing to watch for is:

for ($i = 0; $i < count($array); $i++) {

That's an expensive loop, since it calls count on every single iteration. So long as you're not doing that, I don't think it really matters...

As for the reference making a difference, PHP uses copy-on-write, so if you don't write to the array, there will be relatively little overhead while looping. However, if you start modifying the array within the array, that's where you'll start seeing differences between them (since one will need to copy the entire array, and the reference can just modify inline)...

As for the iterators, foreach is equivalent to:

$it->rewind();
while ($it->valid()) {
    $key = $it->key();     // If using the $key => $value syntax
    $value = $it->current();

    // Contents of loop in here

    $it->next();
}

As far as there being faster ways to iterate, it really depends on the problem. But I really need to ask, why? I understand wanting to make things more efficient, but I think you're wasting your time for a micro-optimization. Remember, Premature Optimization Is The Root Of All Evil...

Edit: Based upon the comment, I decided to do a quick benchmark run...

$a = array();
for ($i = 0; $i < 10000; $i++) {
    $a[] = $i;
}

$start = microtime(true);
foreach ($a as $k => $v) {
    $a[$k] = $v + 1;
}
echo "Completed in ", microtime(true) - $start, " Seconds\n";

$start = microtime(true);
foreach ($a as $k => &$v) {
    $v = $v + 1;
}
echo "Completed in ", microtime(true) - $start, " Seconds\n";

$start = microtime(true);
foreach ($a as $k => $v) {}
echo "Completed in ", microtime(true) - $start, " Seconds\n";

$start = microtime(true);
foreach ($a as $k => &$v) {}    
echo "Completed in ", microtime(true) - $start, " Seconds\n";

And the results:

Completed in 0.0073502063751221 Seconds
Completed in 0.0019769668579102 Seconds
Completed in 0.0011849403381348 Seconds
Completed in 0.00111985206604 Seconds

So if you're modifying the array in the loop, it's several times faster to use references...

And the overhead for just the reference is actually less than copying the array (this is on 5.3.2)... So it appears (on 5.3.2 at least) as if references are significantly faster...

Your quotes are in the wrong spot. Here's a simple example:

<div style={{backgroundColor: "#FF0000"}}>red</div>

The problem is

When a Scanner is closed, it will close its input source if the source implements the Closeable interface.

http://docs.oracle.com/javase/1.5.0/docs/api/java/util/Scanner.html

Thus scan.close() closes System.in.

To fix it you can make

Scanner scan static and do not close it in PromptCustomerQty. Code below works.

public static void main (String[] args) {   

// Create a customer
// Future proofing the possabiltiies of multiple customers
Customer customer = new Customer("Will");

// Create object for each Product
// (Name,Code,Description,Price)
// Initalize Qty at 0
Product Computer = new Product("Computer","PC1003","Basic Computer",399.99); 
Product Monitor = new Product("Monitor","MN1003","LCD Monitor",99.99);
Product Printer = new Product("Printer","PR1003x","Inkjet Printer",54.23);

// Define internal variables 
// ## DONT CHANGE 
ArrayList<Product> ProductList = new ArrayList<Product>(); // List to store Products
String formatString = "%-15s %-10s %-20s %-10s %-10s %n"; // Default format for output

// Add objects to list
ProductList.add(Computer);
ProductList.add(Monitor);
ProductList.add(Printer);

// Ask users for quantities 
PromptCustomerQty(customer, ProductList);

// Ask user for payment method
PromptCustomerPayment(customer);

// Create the header
PrintHeader(customer, formatString);

// Create Body
PrintBody(ProductList, formatString);   
}

static Scanner scan;

public static void PromptCustomerQty(Customer customer, ArrayList<Product> ProductList)               {
// Initiate a Scanner
scan = new Scanner(System.in);

// **** VARIABLES ****
int qty = 0;

// Greet Customer
System.out.println("Hello " + customer.getName());

// Loop through each item and ask for qty desired
for (Product p : ProductList) {

    do {
    // Ask user for qty
    System.out.println("How many would you like for product: " + p.name);
    System.out.print("> ");

    // Get input and set qty for the object
    qty = scan.nextInt();

    }
    while (qty < 0); // Validation

    p.setQty(qty); // Set qty for object
    qty = 0; // Reset count
}

// Cleanup

}

public static void PromptCustomerPayment (Customer customer) {
// Variables
String payment = "";

// Prompt User
do {
System.out.println("Would you like to pay in full? [Yes/No]");
System.out.print("> ");

payment = scan.next();

} while ((!payment.toLowerCase().equals("yes")) && (!payment.toLowerCase().equals("no")));

// Check/set result
if (payment.toLowerCase() == "yes") {
    customer.setPaidInFull(true);
}
else {
    customer.setPaidInFull(false);
}
}

On a side note, you shouldn't use == for String comparision, use .equals instead.

I was struggling a lot with different solutions including \vspace{-Xmm} on the top and bottom of the page and dealing with warnings and errors. Finally I found this answer:

You can change the margins of just one or more pages and then restore it to its default:

\usepackage{geometry}
...
... 
...
\newgeometry{top=5mm, bottom=10mm}     % use whatever margins you want for left, right, top and bottom.
...
... %<The contents of enlarged page(s)>
...    
\restoregeometry     %so it does not affect the rest of the pages.
...
... 
...

PS:

1- This can also fix the following warning:

LaTeX Warning: Float too large for page by ...pt on input line ...

2- For more detailed answer look at this.

3- I just found that this is more elaboration on Kevin Chen's answer.
