If you are sure that you selected the Generic iOS device and still can't see the option, then you simply have to restart Xcode.

This was the missing solution for me as a cordova developer with Xcode 11.2

Specify a 'display-image' and 'full-size-image' as described here: http://www.informit.com/articles/article.aspx?p=1829415&seqNum=16

iOS8 requires these images

why you need a for-loop for this? the solution is very obvious:

answers.add(answer1);
answers.add(answer2);
answers.add(answer3);

that's it. no for-loop needed.

This is the key:

header("Content-Type: application/octet-stream");

Content-type application/x-pdf-document or application/pdf is sent while sending PDF file. Adobe Reader usually sets the handler for this MIME type so browser will pass the document to Adobe Reader when any of PDF MIME types is received.

If NEW_TABLE already exists then ...

insert into new_table 
select * from old_table
/

If you want to create NEW_TABLE based on the records in OLD_TABLE ...

create table new_table as 
select * from old_table
/

If the purpose is to create a new but empty table then use a WHERE clause with a condition which can never be true:

create table new_table as 
select * from old_table
where 1 = 2
/

Remember that CREATE TABLE ... AS SELECT creates only a table with the same projection as the source table. The new table does not have any constraints, triggers or indexes which the original table might have. Those still have to be added manually (if they are required).

The script is performed before the DOM of the body is built. Put it all into a function and call it from the onload of the body-element.

Although, the below code does the job, BUT its performance takes a big hit, as you deal with a DataFrame with # records 100k or more:

df.fillna(df.mean())

In my experience, one should replace NaN values (be it with Mean or Median), only where it is required, rather than applying fillna() all over the DataFrame.

I had a DataFrame with 20 variables, and only 4 of them required NaN values treatment (replacement). I tried the above code (Code 1), along with a slightly modified version of it (code 2), where i ran it selectively .i.e. only on variables which had a NaN value

#------------------------------------------------
#----(Code 1) Treatment on overall DataFrame-----

df.fillna(df.mean())

#------------------------------------------------
#----(Code 2) Selective Treatment----------------

for i in df.columns[df.isnull().any(axis=0)]:     #---Applying Only on variables with NaN values
    df[i].fillna(df[i].mean(),inplace=True)

#---df.isnull().any(axis=0) gives True/False flag (Boolean value series), 
#---which when applied on df.columns[], helps identify variables with NaN values

Below is the performance i observed, as i kept on increasing the # records in DataFrame

DataFrame with ~100k records

• Code 1: 22.06 Seconds
• Code 2: 0.03 Seconds

DataFrame with ~200k records

• Code 1: 180.06 Seconds
• Code 2: 0.06 Seconds

DataFrame with ~1.6 Million records

• Code 1: code kept running endlessly
• Code 2: 0.40 Seconds

DataFrame with ~13 Million records

• Code 1: --did not even try, after seeing performance on 1.6 Mn records--
• Code 2: 3.20 Seconds

Apologies for a long answer ! Hope this helps !

It depends on the browser. If you look in the blog post Array.prototype.slice vs manual array creation, there is a rough guide to performance of each:

Results:

The cex parameter will do that for you.

a <- c(3, 2, 2, 2, 1, 2 )
barplot(a, beside = T,
        col = 1:6, space = c(0, 2))
legend("topright", 
       legend = c("a", "b", "c", "d", "e", "f"), 
       fill = 1:6, ncol = 2,
       cex = 0.75)

How do I set up the basic authorization?

All you need to do is use -u, --user USER[:PASSWORD]. Behind the scenes curl builds the Authorization header with base64 encoded credentials for you.

Example:

curl -u username:password -i -H 'Accept:application/json' http://example.com

Normalize.css is mainly a set of styles, based on what its author thought would look good, and make it look consistent across browsers. Reset basically strips styling from elements so you have more control over the styling of everything.

I use both.

Some styles from Reset, some from Normalize.css. For example, from Normalize.css, there's a style to make sure all input elements have the same font, which doesn't occur (between text inputs and textareas). Reset has no such style, so inputs have different fonts, which is not normally wanted.

So bascially, using the two CSS files does a better job 'Equalizing' everything ;)

Use Parameter Binding as describe completely here : http://www.asp.net/web-api/overview/formats-and-model-binding/parameter-binding-in-aspnet-web-api

I haven't seen this done before, but this is how it was done for emulating IE 8/7 when using IE 9:

<meta http-equiv="X-UA-Compatible" content="IE=EmulateIE9">

If not, then try this one:

<meta http-equiv="X-UA-Compatible" content="IE=9">

Add those to your header with the other meta tags. This should force IE10 to render as IE9.

Another option you could do (assuming you are using PHP) is add this to your .htaccess file:

Header set X-UA-Compatible "IE=9"

This will perform the action universally, rather than having to worry about adding the meta tag to all of your headers.

It might help some people who are struggling to get Facebook to read Open Graph nicely...

Have a look at the source code that is generated by browser using Firefox, Chrome or another desktop browser (many mobiles won't do view source) and make sure there is no blank lines before the doctype line or head tag... If there is Facebook will have a complete tantrum and throw it's toys out of the pram! (Best description!) Remove Blank Line - happy Facebook... took me about 1.5 - 2 hours to spot this!

And in Bash

            "Prcess Hanging Due To Exception With PID :"${pid}
   fi

OR in Bash

line1=`tail -3 /opt/Scripts/wowzaDataSync.log | grep "AmazonHttpClient" | head -1`
vpid=`ps -ef|  grep wowzaDataSync | grep -v grep  | awk '{print $2}'`
echo "-------->"${line1}

            "Prcess Hanging Due To Exception With PID :"${pid}
  fi

Interesting:

1. You declared an array var $my_value = array();
2. Pushed value into it $a->my_value[] = 'b';
3. Assigned a string to variable. (so it is no more array) $a->set_value ('c');
4. Tried to push a value into array, that does not exist anymore. (it's string) $a->my_class('d');

And your foreach wont work anymore.

On Mac OS X:

$ brew install tomcat-native
==> tomcat-native
In order for tomcat's APR lifecycle listener to find this library, you'll
need to add it to java.library.path. This can be done by adding this line
to $CATALINA_HOME/bin/setenv.sh

  CATALINA_OPTS="$CATALINA_OPTS -Djava.library.path=/usr/local/opt/tomcat-native/lib"

If $CATALINA_HOME/bin/setenv.sh doesn't exist, create it and make it executable.

Then add it to the eclipse's tomcat arguments (double-click Server > Open Launch Configuration > Arguments tab > VM arguments)

-Djava.library.path=/usr/local/opt/tomcat-native/lib

String[][] shades = new String[intSize][intSize];
 // print array in rectangular form
 for (int r=0; r<shades.length; r++) {
     for (int c=0; c<shades[r].length; c++) {
         shades[r][c]="hello";//your value
     }
 }

use the HorizontalContentAlignment property.

Sample

<Label HorizontalContentAlignment="Center"/>

Based on @amateur's answer (and now incorporating the fix from @j_walker_dev comment), but taking into account the comment about hash tags in the url I use the following:

function updateQueryStringParameter(uri, key, value) {
  var re = new RegExp("([?&])" + key + "=.*?(&|#|$)", "i");
  if (uri.match(re)) {
    return uri.replace(re, '$1' + key + "=" + value + '$2');
  } else {
    var hash =  '';
    if( uri.indexOf('#') !== -1 ){
        hash = uri.replace(/.*#/, '#');
        uri = uri.replace(/#.*/, '');
    }
    var separator = uri.indexOf('?') !== -1 ? "&" : "?";    
    return uri + separator + key + "=" + value + hash;
  }
}

Edited to fix [?|&] in regex which should of course be [?&] as pointed out in the comments

Edit: Alternative version to support removing URL params as well. I have used value === undefined as the way to indicate removal. Could use value === false or even a separate input param as wanted.

function updateQueryStringParameter(uri, key, value) {
  var re = new RegExp("([?&])" + key + "=.*?(&|#|$)", "i");
  if( value === undefined ) {
    if (uri.match(re)) {
        return uri.replace(re, '$1$2');
    } else {
        return uri;
    }
  } else {
    if (uri.match(re)) {
        return uri.replace(re, '$1' + key + "=" + value + '$2');
    } else {
    var hash =  '';
    if( uri.indexOf('#') !== -1 ){
        hash = uri.replace(/.*#/, '#');
        uri = uri.replace(/#.*/, '');
    }
    var separator = uri.indexOf('?') !== -1 ? "&" : "?";    
    return uri + separator + key + "=" + value + hash;
  }
  }  
}

use SELECT...INTO

The SELECT INTO statement creates a new table and populates it with the result set of the SELECT statement. SELECT INTO can be used to combine data from several tables or views into one table. It can also be used to create a new table that contains data selected from a linked server.

Example,

SELECT col1, col2 INTO #a -- <<== creates temporary table
FROM   tablename

• Inserting Rows by Using SELECT INTO

Standard Syntax,

SELECT  col1, ....., col@      -- <<== select as many columns as you want
        INTO [New tableName]
FROM    [Source Table Name]

The cleanest way to fix this is to apply the vertical-align: top property to you CSS rules:

#div1 div {
   width:30px;height:30px;
   border:blue 1px solid;
   display:inline-block;
   *display:inline;zoom:1;
   margin:0px;outline:none;
   vertical-align: top;
}

If you were to add content to your div's, then using either line-height: 0 or font-size: 0 would cause problems with your text layout.

See fiddle: http://jsfiddle.net/audetwebdesign/eJqaZ/

Where This Problem Comes From

This problem can arise when a browser is in "quirks" mode. In this example, changing the doctype from:

<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

to

<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.0 Strict//EN">

will change how the browser deals with extra whitespace.

In quirks mode, the whitespace is ignored, but preserved in strict mode.

References:

html doctype adds whitespace?

https://developer.mozilla.org/en/Images,_Tables,_and_Mysterious_Gaps

class Countries < ActiveRecord::Base
    self.table_name = "cc"
end

In Rails 3.x this is the way to specify the table name.

for a in soup("p",{'id':'pagination'})[0]("a",{'href': True}):
        if createunicode(a.text) in ['<','<']:
            links.append(a.attrMap['href'])
        else:
            continue

It works for me.

If you have access to other AMD gpu's please see here: https://github.com/ROCmSoftwarePlatform/hiptensorflow/tree/hip/rocm_docs

This should get you going in the right direction for tensorflow on the ROCm platform, but Selly's post about https://rocm.github.io/hardware.html is the deal with this route. That page is not an exhaustive list, I found out on my own that the Xeon E5 v2 Ivy Bridge works fine with ROCm even though they list v3 or newer, graphics cards however are a bit more picky. gfx8 or newer with a few small exceptions, polaris and maybe others as time goes on.

UPDATE - It looks like hiptensorflow has an option for opencl support during configure. I would say investigate the link even if you don't have gfx8+ or polaris gpu if the opencl implementation works. It is a long winded process but an hour or three (depending on hardware) following a well written instruction isn't too much to lose to find out.

1. literal_eval, a somewhat safer version of eval (will only evaluate literals ie strings, lists etc):

   from ast import literal_eval
   
   python_dict = literal_eval("{'a': 1}")
   

2. json.loads but it would require your string to use double quotes:

   import json
   
   python_dict = json.loads('{"a": 1}')
   

I see that the autoload functions only receive the "full" classname - with all the namespaces preceeding it - in the following two cases:

[a] $a = new The\Full\Namespace\CoolClass();

[b] use The\Full\Namespace as SomeNamespace; (at the top of your source file) followed by $a = new SomeNamespace\CoolClass();

I see that the autoload functions DO NOT receive the full classname in the following case:

[c] use The\Full\Namespace; (at the top of your source file) followed by $a = new CoolClass();

UPDATE: [c] is a mistake and isn't how namespaces work anyway. I can report that, instead of [c], the following two cases also work well:

[d] use The\Full\Namespace; (at the top of your source file) followed by $a = new Namespace\CoolClass();

[e] use The\Full\Namespace\CoolClass; (at the top of your source file) followed by $a = new CoolClass();

Hope this helps.

clean docker

docker stop $(docker ps -qa) && docker system prune -af --volumes

build again

docker build .

docker-compose build

docker-compose up

To add to the above answers, ensure you define your function like this:

public function functionName(Request $request)  {
       //
}

Note the "(Request $request)", now set a session like this:

$request->session()->put('key', 'value');

And retrieve the session in this way:

$data = $request->session()->get('key');

To erase the session try this:

$request->session()->forget('key');  

or

$request->session()->flush();

Do not run the application using node.js icon.

Go to All Programmes->Node.js->Node.js command prompt.

Below is example screen shot.

Here's another approach using json and rouge:

require 'json'
require 'rouge'

formatter = Rouge::Formatters::Terminal256.new
json_lexer = Rouge::Lexers::JSON.new

puts formatter.format(json_lexer.lex(JSON.pretty_generate(JSON.parse(response))))

(parses response from e.g. RestClient)

@IBAction func ImportImage(_ sender: Any)
{
    let image = UIImagePickerController()
    image.delegate = self

    image.sourceType = UIImagePickerController.SourceType.photoLibrary

    image.allowsEditing = false

    self.present(image, animated: true)
    {
        //After it is complete
    }


}

func imagePickerController(_ picker: UIImagePickerController, didFinishPickingMediaWithInfo info: [UIImagePickerController.InfoKey : Any]) {
    if let image = info[UIImagePickerController.InfoKey.originalImage] as? UIImage
    {
        myimage.image = image
    }
    else{
        //
    }
    self.dismiss(animated: true, completion: nil)

    do {
        try context.save()
    } catch {
        print("Could not save. \(error), \(error.localizedDescription)")
    }

}

Add UINavigationControllerDelegate, UIImagePickerControllerDelegate delegates in the class definition

findOne, modify fields & save

User.findOne({username: oldUsername})
  .then(user => {
    user.username = newUser.username;
    user.password = newUser.password;
    user.rights = newUser.rights;

    user.markModified('username');
    user.markModified('password');
    user.markModified('rights');

    user.save(err => console.log(err));
});

OR findOneAndUpdate

User.findOneAndUpdate({username: oldUsername}, {$set: { username: newUser.username, user: newUser.password, user:newUser.rights;}}, {new: true}, (err, doc) => {
    if (err) {
        console.log("Something wrong when updating data!");
    }
    console.log(doc);
});

I guess you forgot .btn-primary:focus property and comma after .btn-primary

You also can use less and redefine some colors in variables.less file

With this in mind your code will be look like this:

.btn-primary,_x000D_
.btn-primary:hover,_x000D_
.btn-primary:active,_x000D_
.btn-primary:visited,_x000D_
.btn-primary:focus {_x000D_
    background-color: #8064A2;_x000D_
    border-color: #8064A2;_x000D_
}

The reason behind posted this answer is I tried many solution but no one work properly, most of the answer not work in case where have to set cookie first time, and got result cookie not sync first time, Please use this solution it work for both iOS >= 11.0 <= iOS 11 till 8.0, also work with cookie sync first time.

For iOS >= 11.0 -- Swift 4.2

Get http cookies and set in wkwebview cookie store like this way, it's very tricky point to load your request in wkwebview, must sent request for loading when cookies gonna be set completely, here is function that i wrote.

Call function with closure in completion you call load webview. FYI this function only handle iOS >= 11.0

self.WwebView.syncCookies {
    if let request = self.request {
       self.WwebView.load(request)
    }
}

Here is implementation for syncCookies function.

func syncCookies(completion:@escaping ()->Void) {

if #available(iOS 11.0, *) {

      if let yourCookie = "HERE_YOUR_HTTP_COOKIE_OBJECT" {
        self.configuration.websiteDataStore.httpCookieStore.setCookie(yourCookie, completionHandler: {
              completion()
        })
     }
  } else {
  //Falback just sent 
  completion()
}
}

For iOS 8 till iOS 11

you need to setup some extra things you need to set two time cookies one through using WKUserScript and dont forget to add cookies in request as well, otherwise your cookie not sync first time and you will see you page not load first time properly. this is the heck that i found to support cookies for iOS 8.0

before you Wkwebview object creation.

func setUpWebView() {

    let userController: WKUserContentController = WKUserContentController.init()

    if IOSVersion.SYSTEM_VERSION_LESS_THAN(version: "11.0") {
        if let cookies = HTTPCookieStorage.shared.cookies {
            if let script = getJSCookiesString(for: cookies) {
                cookieScript = WKUserScript(source: script, injectionTime: .atDocumentStart, forMainFrameOnly: false)
                userController.addUserScript(cookieScript!)
            }
        }
    }

    let webConfiguration = WKWebViewConfiguration()
    webConfiguration.processPool = BaseWebViewController.processPool


    webConfiguration.userContentController = userController


    let customFrame = CGRect.init(origin: CGPoint.zero, size: CGSize.init(width: 0.0, height: self.webContainerView.frame.size.height))
    self.WwebView = WKWebView (frame: customFrame, configuration: webConfiguration)
    self.WwebView.translatesAutoresizingMaskIntoConstraints = false
    self.webContainerView.addSubview(self.WwebView)
    self.WwebView.uiDelegate = self
    self.WwebView.navigationDelegate = self
    self.WwebView.allowsBackForwardNavigationGestures = true // A Boolean value indicating whether horizontal swipe gestures will trigger back-forward list navigations
    self.WwebView.addObserver(self, forKeyPath: #keyPath(WKWebView.estimatedProgress), options: .new, context: nil)


 self.view.addConstraint(NSLayoutConstraint(item: WwebView, attribute: .trailing, relatedBy: .equal, toItem: self.webContainerView, attribute: .trailing, multiplier: 1, constant: 0))
    self.view.addConstraint(NSLayoutConstraint(item: WwebView, attribute: .leading, relatedBy: .equal, toItem: self.webContainerView, attribute: .leading, multiplier: 1, constant: 0))
    self.view.addConstraint(NSLayoutConstraint(item: WwebView, attribute: .top, relatedBy: .equal, toItem: self.webContainerView, attribute: .top, multiplier: 1, constant: 0))
    self.view.addConstraint(NSLayoutConstraint(item: WwebView, attribute: .bottom, relatedBy: .equal, toItem: self.webContainerView, attribute: .bottom, multiplier: 1, constant: 0))


}

Focus on this function getJSCookiesString

 public func getJSCookiesString(for cookies: [HTTPCookie]) -> String? {

    var result = ""
    let dateFormatter = DateFormatter()
    dateFormatter.timeZone = TimeZone(abbreviation: "UTC")
    dateFormatter.dateFormat = "EEE, d MMM yyyy HH:mm:ss zzz"

    for cookie in cookies {
        if cookie.name == "yout_cookie_name_want_to_sync" {
            result += "document.cookie='\(cookie.name)=\(cookie.value); domain=\(cookie.domain); path=\(cookie.path); "
            if let date = cookie.expiresDate {
                result += "expires=\(dateFormatter.string(from: date)); "
            }
            if (cookie.isSecure) {
                result += "secure; "
            }
            result += "'; "
        }

    }

    return result
}

Here is other step wkuserscript not sync cookies immediately, there a lot of heck to load first time page with cookie one is to reload webview again if it terminate process but i don't recommend to use it, its not good for user point of view, heck is whenever you ready to load request set cookies in request header as well like this way, don't forget to add iOS version check. before load request call this function.

request?.addCookies()

i wrote extension for URLRequest

extension URLRequest {

internal mutating func addCookies() {
    //"appCode=anAuY28ucmFrdXRlbi5yZXdhcmQuaW9zLXpOQlRTRmNiejNHSzR0S0xuMGFRb0NjbUg4Ql9JVWJH;rpga=kW69IPVSYZTo0JkZBicUnFxC1g5FtoHwdln59Z5RNXgJoMToSBW4xAMqtf0YDfto;rewardadid=D9F8CE68-CF18-4EE6-A076-CC951A4301F6;rewardheader=true"
    var cookiesStr: String = ""

    if IOSVersion.SYSTEM_VERSION_LESS_THAN(version: "11.0") {
        let mutableRequest = ((self as NSURLRequest).mutableCopy() as? NSMutableURLRequest)!
        if let yourCookie = "YOUR_HTTP_COOKIE_OBJECT" {
            // if have more than one cookies dont forget to add ";" at end
            cookiesStr += yourCookie.name + "=" + yourCookie.value + ";"

            mutableRequest.setValue(cookiesStr, forHTTPHeaderField: "Cookie")
            self = mutableRequest as URLRequest

        }
    }

  }
}

now you ready to go for testing iOS > 8

Changing the value of sys.stdout does change the destination of all calls to print. If you use an alternative way to change the destination of print, you will get the same result.

Your bug is somewhere else:

• it could be in the code you removed for your question (where does filename come from for the call to open?)
• it could also be that you are not waiting for data to be flushed: if you print on a terminal, data is flushed after every new line, but if you print to a file, it's only flushed when the stdout buffer is full (4096 bytes on most systems).

CPython (the classic and prevalent implementation of Python) can't have more than one thread executing Python bytecode at the same time. This means compute-bound programs will only use one core. I/O operations and computing happening inside C extensions (such as numpy) can operate simultaneously.

Other implementation of Python (such as Jython or PyPy) may behave differently, I'm less clear on their details.

The usual recommendation is to use many processes rather than many threads.

I had the same problem and the only solution I found was putting everything that used the FB statement inside the init script, I also used async loading, so the callback function is after everything that needs FB. I have a common page dinamycally loaded with php so many parts need different facebook functions controlled by php if statements which is making everything a bit messy, but is working!. if I try taking any FB declaration out of the loading script, then firefox shows the "FB is not defined" message. Hope it helps in anything.

This should work for you

//Retrieve Minimum Date
var MinDate = (from d in dataRows select d.Date).Min();

//Retrieve Maximum Date
var MaxDate = (from d in dataRows select d.Date).Max();

NXJSON is full-featured yet very small (~400 lines of code) JSON parser, which has easy to use API:

const nx_json* json=nx_json_parse_utf8(code);
printf("hello=%s\n", nx_json_get(json, "hello")->text_value);
const nx_json* arr=nx_json_get(json, "my-array");
int i;
for (i=0; i<arr->length; i++) {
  const nx_json* item=nx_json_item(arr, i);
  printf("arr[%d]=(%d) %ld\n", i, (int)item->type, item->int_value);
}
nx_json_free(json);

Most answers here will tell you how to create an empty DataFrame and fill it out, but no one will tell you that it is a bad thing to do.

Here is my advice: Accumulate data in a list, not a DataFrame.

Use a list to collect your data, then initialise a DataFrame when you are ready. Either a list-of-lists or list-of-dicts format will work, pd.DataFrame accepts both.

data = []
for a, b, c in some_function_that_yields_data():
    data.append([a, b, c])

df = pd.DataFrame(data, columns=['A', 'B', 'C'])

Pros of this approach:

1. It is always cheaper to append to a list and create a DataFrame in one go than it is to create an empty DataFrame (or one of NaNs) and append to it over and over again.

2. Lists also take up less memory and are a much lighter data structure to work with, append, and remove (if needed).

3. dtypes are automatically inferred (rather than assigning object to all of them).

4. A RangeIndex is automatically created for your data, instead of you having to take care to assign the correct index to the row you are appending at each iteration.

If you aren't convinced yet, this is also mentioned in the documentation:

Iteratively appending rows to a DataFrame can be more computationally intensive than a single concatenate. A better solution is to append those rows to a list and then concatenate the list with the original DataFrame all at once.

But what if my function returns smaller DataFrames that I need to combine into one large DataFrame?

That's fine, you can still do this in linear time by growing or creating a python list of smaller DataFrames, then calling pd.concat.

small_dfs = []
for small_df in some_function_that_yields_dataframes():
    small_dfs.append(small_df)

large_df = pd.concat(small_dfs, ignore_index=True)

or, more concisely:

large_df = pd.concat(
    list(some_function_that_yields_dataframes()), ignore_index=True)

These options are horrible

append or concat inside a loop

Here is the biggest mistake I've seen from beginners:

df = pd.DataFrame(columns=['A', 'B', 'C'])
for a, b, c in some_function_that_yields_data():
    df = df.append({'A': i, 'B': b, 'C': c}, ignore_index=True) # yuck
    # or similarly,
    # df = pd.concat([df, pd.Series({'A': i, 'B': b, 'C': c})], ignore_index=True)

Memory is re-allocated for every append or concat operation you have. Couple this with a loop and you have a quadratic complexity operation.

The other mistake associated with df.append is that users tend to forget append is not an in-place function, so the result must be assigned back. You also have to worry about the dtypes:

df = pd.DataFrame(columns=['A', 'B', 'C'])
df = df.append({'A': 1, 'B': 12.3, 'C': 'xyz'}, ignore_index=True)

df.dtypes
A     object   # yuck!
B    float64
C     object
dtype: object

Dealing with object columns is never a good thing, because pandas cannot vectorize operations on those columns. You will need to do this to fix it:

df.infer_objects().dtypes
A      int64
B    float64
C     object
dtype: object

loc inside a loop

I have also seen loc used to append to a DataFrame that was created empty:

df = pd.DataFrame(columns=['A', 'B', 'C'])
for a, b, c in some_function_that_yields_data():
    df.loc[len(df)] = [a, b, c]

As before, you have not pre-allocated the amount of memory you need each time, so the memory is re-grown each time you create a new row. It's just as bad as append, and even more ugly.

Empty DataFrame of NaNs

And then, there's creating a DataFrame of NaNs, and all the caveats associated therewith.

df = pd.DataFrame(columns=['A', 'B', 'C'], index=range(5))
df
     A    B    C
0  NaN  NaN  NaN
1  NaN  NaN  NaN
2  NaN  NaN  NaN
3  NaN  NaN  NaN
4  NaN  NaN  NaN

It creates a DataFrame of object columns, like the others.

df.dtypes
A    object  # you DON'T want this
B    object
C    object
dtype: object

Appending still has all the issues as the methods above.

for i, (a, b, c) in enumerate(some_function_that_yields_data()):
    df.iloc[i] = [a, b, c]

The Proof is in the Pudding

Timing these methods is the fastest way to see just how much they differ in terms of their memory and utility.

Benchmarking code for reference.

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

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

All answers here are still using the FormData API. It is like a "multipart/form-data" upload without a form. You can also upload the file directly as content inside the body of the POST request using xmlHttpRequest like this:

var xmlHttpRequest = new XMLHttpRequest();

var file = ...file handle...
var fileName = ...file name...
var target = ...target...
var mimeType = ...mime type...

xmlHttpRequest.open('POST', target, true);
xmlHttpRequest.setRequestHeader('Content-Type', mimeType);
xmlHttpRequest.setRequestHeader('Content-Disposition', 'attachment; filename="' + fileName + '"');
xmlHttpRequest.send(file);

Content-Type and Content-Disposition headers are used for explaining what we are sending (mime-type and file name).

I posted similar answer also here.

Have a look at PDFSharp

It is open source and it is written in .NET, I use it myself for some PDF invoice generation.

TempData in Asp.Net MVC is one of the very useful feature. It is used to pass data from current request to subsequent request. In other words if we want to send data from one page to another page while redirection occurs, we can use TempData, but we need to do some consideration in code to achieve this feature in MVC. Because the life of TempData is very short and lies only till the target view is fully loaded. But, we can use Keep() method to persist data in TempData.

If your query is something like this SELECT Count(*) FROM tranbook, then do this rs.next(); System.out.println(rs.getInt("Count(*)"));

Simple yet Python 2 & Python 3 compatible way comes with six library:

from six.moves import urllib
urllib.request.urlretrieve("http://www.example.com/songs/mp3.mp3", "mp3.mp3")

The 2nd file needs to know about the existance of your variable. To do this you declare the variable again but use the keyword extern in front of it. This tells the compiler that the variable is available but declared somewhere else, thus prevent instanciating it (again, which would cause clashes when linking). While you can put the extern declaration in the C file itself it's common style to have an accompanying header (i.e. .h) file for each .c file that provides functions or variables to others which hold the extern declaration. This way you avoid copying the extern declaration, especially if it's used in multiple other files. The same applies for functions, though you don't need the keyword extern for them.

That way you would have at least three files: the source file that declares the variable, it's acompanying header that does the extern declaration and the second source file that #includes the header to gain access to the exported variable (or any other symbol exported in the header). Of course you need all source files (or the appropriate object files) when trying to link something like that, as the linker needs to resolve the symbol which is only possible if it actually exists in the files linked.

Multiple SQL statements must be executed with the mysqli_multi_query() function.

Example (MySQLi Object-oriented):

    <?php
$servername = "localhost";
$username = "username";
$password = "password";
$dbname = "myDB";

// Create connection
$conn = new mysqli($servername, $username, $password, $dbname);
// Check connection
if ($conn->connect_error) {
    die("Connection failed: " . $conn->connect_error);
} 

$sql = "INSERT INTO names (firstname, lastname)
VALUES ('inpute value here', 'inpute value here');";
$sql .= "INSERT INTO phones (landphone, mobile)
VALUES ('inpute value here', 'inpute value here');";

if ($conn->multi_query($sql) === TRUE) {
    echo "New records created successfully";
} else {
    echo "Error: " . $sql . "<br>" . $conn->error;
}

$conn->close();
?>

Your E class doesn't have a member of type struct X, you've just defined a nested struct X in there (i.e. you've defined a new type).

Try:

#include <iostream>

class E
{
    public: 
    struct X { int v; };
    X x; // an instance of `struct X`
};

int main(){

    E object;
    object.x.v = 1;

    return 0;
}

You'll need to open the workbook to refer to it.

Sub Setwbk()

    Dim wbk As Workbook

    Set wbk = Workbooks.Open("F:\Quarterly Reports\2012 Reports\New Reports\ _
        Master Benchmark Data Sheet.xlsx")

End Sub

_{* Follow Doug's answer if the workbook is already open. For the sake of making this answer as complete as possible, I'm including my comment on his answer:}

Why do I have to "set" it?

Set is how VBA assigns object variables. Since a Range and a Workbook/Worksheet are objects, you must use Set with these.

Same as what clairesuzy answered, except you can get a similar result by adding display: flex instead of white-space: nowrap. Using display: flex will collapse the img "margins", in case that behavior is preferred.

Instead of hitting "F5" Just hit:

"Ctrl + F5"

Note: if you upgrade from spring boot 1 to spring boot 2 there is a ResponseStatusException which has a Http error code and a description.

So, you can effectively use generics they way it is intended.

The only case which is a bit challenging for me, is the response type for a status 204 (ok with no body). I tend to mark those methods as ResponseEntity<?>, because ResponseEntity<Void> is less predictive.

sys.argv represents the command line options you execute a script with.

sys.argv[0] is the name of the script you are running. All additional options are contained in sys.argv[1:].

You are attempting to open a file that uses sys.argv[1] (the first argument) as what looks to be the directory.

Try running something like this:

python ConcatenateFiles.py /tmp

The easiest way is:

s = '"sajdkasjdsaasdasdasds"' 
import json
s = json.loads(s)

var column1RelArray = [];
$('#column1 li').each(function(){
    column1RelArray.push($(this).attr('rel'));
});

or fp style

var column1RelArray = $('#column1 li').map(function(){ 
    return $(this).attr('rel'); 
});

This will delete the dataframe and will release the RAM/memory

del [[df_1,df_2]]
gc.collect()
df_1=pd.DataFrame()
df_2=pd.DataFrame()

the data-frame will be explicitly set to null

in the above statements

Firstly, the self reference of the dataframe is deleted meaning the dataframe is no longer available to python there after all the references of the dataframe is collected by garbage collector (gc.collect()) and then explicitly set all the references to empty dataframe.

more on the working of garbage collector is well explained in https://stackify.com/python-garbage-collection/

a <- 1:120
b <- a[seq(1, length(a), 6)]

provided I understood correctly, you should look for binascii.unhexlify

import binascii
a='45222e'
s=binascii.unhexlify(a)
b=[ord(x) for x in s]

I had many issues involving C# and SqlServer. I ended up doing the following:

1. On SQL Server I use the DateTime column type
2. On c# I use the .ToString("yyyy-MM-dd HH:mm:ss") method

Also make sure that all your machines run on the same timezone.

Regarding the different result sets you get, your first example is "July First" while the second is "4th of July" ...

Also, the second example can be also interpreted as "April 7th", it depends on your server localization configuration (my solution doesn't suffer from this issue).

EDIT: hh was replaced with HH, as it doesn't seem to capture the correct hour on systems with AM/PM as opposed to systems with 24h clock. See the comments below.

select unique is not valid syntax for what you are trying to do

you want to use either select distinct or select distinctrow

And actually, you don't even need distinct/distinctrow in what you are trying to do. You can eliminate duplicates by choosing the appropriate union statement parameters.

the below query by itself will only provide distinct values

select col from table1 
union 
select col from table2

if you did want duplicates you would have to do

select col from table1 
union all
select col from table2

We got this error when the connection string to our database was incorrect. The key to figuring this out was running the dotnet blah.dll which provided a stacktrace showing us that the sql server instance specified could not be found. Hope this helps someone.

Just use this : Make sure using nibName otherwise preloaded views of xib will not show :

var vc : ViewController = ViewController(nibName: "ViewController", bundle: nil) //change this to your class name

 self.presentViewController(vc, animated: true, completion: nil)

The problem is here:

document.getElementById(elementId).value

You know that HTMLElement returned from getElementById() is actually an instance of HTMLInputElement inheriting from it because you are passing an ID of input element. Similarly in statically typed Java this won't compile:

public Object foo() {
  return 42;
}

foo().signum();

signum() is a method of Integer, but the compiler only knows the static type of foo(), which is Object. And Object doesn't have a signum() method.

But the compiler can't know that, it can only base on static types, not dynamic behaviour of your code. And as far as the compiler knows, the type of document.getElementById(elementId) expression does not have value property. Only input elements have value.

For a reference check HTMLElement and HTMLInputElement in MDN. I guess Typescript is more or less consistent with these.

It depends on which version of Oracle? Older versions require exp (export), newer versions use expdp (data pump); exp was deprecated but still works most of the time.

Before starting, note that Data Pump exports to the server-side Oracle "directory", which is an Oracle symbolic location mapped in the database to a physical location. There may be a default directory (DATA_PUMP_DIR), check by querying DBA_DIRECTORIES:

  SQL> select * from dba_directories;

... and if not, create one

  SQL> create directory DATA_PUMP_DIR as '/oracle/dumps';
  SQL> grant all on directory DATA_PUMP_DIR to myuser;    -- DBAs dont need this grant

Assuming you can connect as the SYSTEM user, or another DBA, you can export any schema like so, to the default directory:

 $ expdp system/manager schemas=user1 dumpfile=user1.dpdmp

Or specifying a specific directory, add directory=<directory name>:

 C:\> expdp system/manager schemas=user1 dumpfile=user1.dpdmp directory=DUMPDIR

With older export utility, you can export to your working directory, and even on a client machine that is remote from the server, using:

 $ exp system/manager owner=user1 file=user1.dmp

Make sure the export is done in the correct charset. If you haven't setup your environment, the Oracle client charset may not match the DB charset, and Oracle will do charset conversion, which may not be what you want. You'll see a warning, if so, then you'll want to repeat the export after setting NLS_LANG environment variable so the client charset matches the database charset. This will cause Oracle to skip charset conversion.

Example for American UTF8 (UNIX):

 $ export NLS_LANG=AMERICAN_AMERICA.AL32UTF8

Windows uses SET, example using Japanese UTF8:

 C:\> set NLS_LANG=Japanese_Japan.AL32UTF8

More info on Data Pump here: http://docs.oracle.com/cd/B28359_01/server.111/b28319/dp_export.htm#g1022624

jQuery lib has to be loaded first. In my case, i was loading bootstrap lib first, also tried tag with target and firing a click trigger. But the main issue was - jquery has to be loaded first.

for some weird reason bootstrap tabs were not working for me until i was using href like:-

<li class="nav-item"><a class="nav-link" href="#a" data-toggle="tab">First</a></li>

but it started working as soon as i replaced href with data-target like:-

<li class="nav-item"><a class="nav-link" data-target="#a" data-toggle="tab">First</a></li>

\ is used for escape sequences in programming languages.

\n prints a newline
\\ prints a backslash
\" prints "
\t prints a tabulator
\b moves the cursor one back

Example: http://xxjjnn.com/linktablerow.html

Link entire row:

<table>
  <tr onclick="location.href='SomeWherrrreOverTheWebsiiiite.html'">**
    <td> ...content... </td>
    <td> ...content... </td>
    ...
  </tr>
</table>

Iff you'd like to do highlight on mouseover for the entire row, then:

<table class="nogap">
  <tr class="lovelyrow" onclick="location.href='SomeWherrrreOverTheWebsiiiite.html'">**
     ...
  </tr>
</table>

with something like the following for css, which will remove the gap between the table cells and change the background on hover:

tr.lovelyrow{
  background-color: hsl(0,0%,90%);
}

tr.lovelyrow:hover{
  background-color: hsl(0,0%,40%);
  cursor: pointer;
}

table.nogap{
  border-collapse: collapse;
}

Iff you are using Rails 3.0.9 then you might find this example code useful:

Sea has many Fish, Fish has many Scales, here is snippet of app/view/fish/index.erb

<table>
<% @fishies.each do |fish| %>
  <tr onclick="location.href='<%= sea_fish_scales_path(@sea, fish) %>'"> 
    <td><%= fish.title %></td>
  </tr>
<% end %>
</table>

with @fishies and @sea are defined in app/controllers/seas_controller.rb

By invoking its toString() method.

Returns a string containing the characters in this sequence in the same order as this sequence. The length of the string will be the length of this sequence.

This may also work:

SELECT 
    COUNT(DISTINCT T.tag) as DistinctTag,
    COUNT(DISTINCT T2.tag) as DistinctPositiveTag
FROM Table T
    LEFT JOIN Table T2 ON T.tag = T2.tag AND T.entryID = T2.entryID AND T2.entryID > 0

You need the entryID condition in the left join rather than in a where clause in order to make sure that any items that only have a entryID of 0 get properly counted in the first DISTINCT.

I linked to the login form by passing the current page as a GET parameter and then used 'next' to redirect to that page. Thanks!

If you want to dump all collections, run this command:

mongodump -d {DB_NAME}   -o /tmp 

It will generate all collections data in json and bson extensions into /tmp/{DB_NAME} directory

It probably is the # sign like tho others have mentioned because this appears to work just fine.

<html xmlns="http://www.w3.org/1999/xhtml">
<head>
    <title></title>

</head>
<body>

    <select id="#ticket_category_clone">
  <option value="hw">Hardware</option>
  <option>fsdf</option>
  <option>sfsd</option>
  <option>sdfs</option>
</select>
<script type="text/javascript">
    (function check() {
        var e = document.getElementById("#ticket_category_clone");
        var str = e.options[e.selectedIndex].text;

        alert(str);
        if (str === "Hardware") { 
            alert('Hi'); 
        }


    })();
</script>
</body>

There are a variety of OCR libraries out there. However, my experience is that the major commercial implementations, ABBYY, Omnipage, and ReadIris, far outdo the open-source or other minor implementations. These commercial libraries are not primarily designed to work with Java, though of course it is possible.

Of course, if your interest is to learn the code, the open-source implementations will do the trick.

Set does not enforce ordering. There is no guarantee that you will always get the "first" element even if you use an iterator over a HashSet like you have done in the question.

If you need to have predictable ordering, you need to use the LinkedHashSet implementation. When you iterate over a LinkedHashSet, you will get the elements in the order you inserted. You still need to use an iterator, because having a get method in LinkedHashSet would need you to use the concrete class everywhere.

for /f "tokens=* delims= " %%f in (myfile) do

This reads a file line-by-line, removing leading spaces (thanks, jeb).

set line=%%f

sets then the line variable to the line just read and

call :procesToken

calls a subroutine that does something with the line

:processToken

is the start of the subroutine mentioned above.

for /f "tokens=1* delims=/" %%a in ("%line%") do

will then split the line at /, but stopping tokenization after the first token.

echo Got one token: %%a

will output that first token and

set line=%%b

will set the line variable to the rest of the line.

if not "%line%" == "" goto :processToken

And if line isn't yet empty (i.e. all tokens processed), it returns to the start, continuing with the rest of the line.

The real trick is: Use a Backslash at the end of the target path where to copy the file. The /Y is for overwriting existing files, if you want no warnings.

Example:

xcopy /Y "C:\file\from\here.txt" "C:\file\to\here\"

use dirname(__FILE__) in a global configuration file.

TL;DR; If you're still having trouble after restarting apache or nginx, also try restarting the php-fpm service.

The answers here don't always satisfy the requirement to force a reload of the php.ini file. On numerous occasions I've taken these steps to be rewarded with no update, only to find the solution I need after also restarting the php-fpm service. So if restarting apache or nginx doesn't trigger a php.ini update although you know the files are updated, try restarting php-fpm as well.

To restart the service:

Note: prepend sudo if not root

Using SysV Init scripts directly:

/etc/init.d/php-fpm restart        # typical
/etc/init.d/php5-fpm restart       # debian-style
/etc/init.d/php7.0-fpm restart     # debian-style PHP 7

Using service wrapper script

service php-fpm restart        # typical
service php5-fpm restart       # debian-style
service php7.0-fpm restart.    # debian-style PHP 7

Using Upstart (e.g. ubuntu):

restart php7.0-fpm         # typical (ubuntu is debian-based) PHP 7
restart php5-fpm           # typical (ubuntu is debian-based)
restart php-fpm            # uncommon

Using systemd (newer servers):

systemctl restart php-fpm.service        # typical
systemctl restart php5-fpm.service       # uncommon
systemctl restart php7.0-fpm.service     # uncommon PHP 7

Or whatever the equivalent is on your system.

I tried the code of William, Thanks brother.

but it's not working as a simple button I have to add form with method="post". Also I have to write submit instead of button.

As of jQuery 1.7, the .on() method is the preferred method for attaching event handlers to a document. For earlier versions, the .bind() method is used for attaching an event handler directly to elements.

$(document).on('mouseover mouseout',".brand", function () {
  $(".star").toggleClass("hovered");
})

I am a retired engineer who grew up with DOS, Fortran, IBM360, etc. in the 60's and like others on this blog I sorely miss the loss of a command line editor in 64-bit Windows. After spending a week browsing the internet and testing editors, I wanted to share my best solution: Notepad++. It's a far cry from DOS EDIT, but there are some side benefits. It is unfortunately a screen editor, requires a mouse, and is consequently slow. On the other hand it is a decent Fortran source editor and has row and column numbers displayed. It can keep multiple tabs for files being edited and even remembers where the cursor was last. I of course keep typing keyboard codes (50 years of habit) but surprisingly at least some of them work. Maybe not a documented feature. I renamed the editor to EDIT.EXE, set up a path to it, and invoke it from command line. It's not too bad. I'm living with it. BTW be careful not to use the tab key in Fortran source. Puts an ASCII 6 in the text. It's invisible and gFortran, at least, can't deal with it. Notepad++ probably has a lot of features that I don't have time to mess with.

A simple way by manipulating string.

$str = stripStr($str, '<script', '</script>');

function stripStr($str, $ini, $fin)
{
    while(($pos = mb_stripos($str, $ini)) !== false)
    {
        $aux = mb_substr($str, $pos + mb_strlen($ini));
        $str = mb_substr($str, 0, $pos).mb_substr($aux, mb_stripos($aux, $fin) + mb_strlen($fin));
    }

    return $str;
}

I usually go with PNG, as it seems to have a few advantages over GIF. There used to be patent restrictions on GIF, but those have expired.

GIFs are suitable for sharp-edged line art (such as logos) with a limited number of colors. This takes advantage of the format's lossless compression, which favors flat areas of uniform color with well defined edges (in contrast to JPEG, which favors smooth gradients and softer images).

GIFs can be used for small animations and low-resolution film clips.

In view of the general limitation on the GIF image palette to 256 colors, it is not usually used as a format for digital photography. Digital photographers use image file formats capable of reproducing a greater range of colors, such as TIFF, RAW or the lossy JPEG, which is more suitable for compressing photographs.

The PNG format is a popular alternative to GIF images since it uses better compression techniques and does not have a limit of 256 colors, but PNGs do not support animations. The MNG and APNG formats, both derived from PNG, support animations, but are not widely used.

1. when you want to use Unicode strings and not just ascii, helpful for internationalisation
2. yes, but it doesn't play well with 0
3. not aware of any that don't
4. wide character is the compiler specific way of handling the fixed length representation of a unicode character, for MSVC it is a 2 byte character, for gcc I understand it is 4 bytes. and a +1 for http://www.joelonsoftware.com/articles/Unicode.html

Method 1 : Using jQuery Ajax Get call (partial page update).

Suitable for when you need to retrieve jSon data from database.

Controller's Action Method

[HttpGet]
public ActionResult Foo(string id)
{
    var person = Something.GetPersonByID(id);
    return Json(person, JsonRequestBehavior.AllowGet);
}

Jquery GET

function getPerson(id) {
    $.ajax({
        url: '@Url.Action("Foo", "SomeController")',
        type: 'GET',
        dataType: 'json',
        // we set cache: false because GET requests are often cached by browsers
        // IE is particularly aggressive in that respect
        cache: false,
        data: { id: id },
        success: function(person) {
            $('#FirstName').val(person.FirstName);
            $('#LastName').val(person.LastName);
        }
    });
}

Person class

public class Person
{
    public string FirstName { get; set; }
    public string LastName { get; set; }
}

Method 2 : Using jQuery Ajax Post call (partial page update).

Suitable for when you need to do partial page post data into database.

Post method is also same like above just replace [HttpPost] on Action method and type as post for jquery method.

For more information check Posting JSON Data to MVC Controllers Here

Method 3 : As a Form post scenario (full page update).

Suitable for when you need to save or update data into database.

View

@using (Html.BeginForm("SaveData","ControllerName", FormMethod.Post))
{        
    @Html.TextBoxFor(model => m.Text)
    
    <input type="submit" value="Save" />
}

Action Method

[HttpPost]
public ActionResult SaveData(FormCollection form)
    {
        // Get movie to update
        return View();
   }

Method 4 : As a Form Get scenario (full page update).

Suitable for when you need to Get data from database

Get method also same like above just replace [HttpGet] on Action method and FormMethod.Get for View's form method.

I hope this will help to you.

If you want be sure you need to check both

SomeProperty == null || SomeProperty == Guid.Empty

Because it can be null 'Nullable' and it can be an empty GUID something like this {00000000-0000-0000-0000-000000000000}

I just would like to contribute with a tail call optimized version by ES6. It's quite simple;

var fibonacci = (n, f = 0, s = 1) => n === 0 ? f : fibonacci(--n, s, f + s);_x000D_
console.log(fibonacci(12));

Create a list of column names you want to add up.

df['total']=df.loc[:,list_name].sum(axis=1)

If you want the sum for certain rows, specify the rows using ':'

Syntax highlighting is controlled by the theme you use, accessible through Preferences -> Color Scheme. Themes highlight different keywords, functions, variables, etc. through the use of scopes, which are defined by a series of regular expressions contained in a .tmLanguage file in a language's directory/package. For example, the JavaScript.tmLanguage file assigns the scopes source.js and variable.language.js to the this keyword. Since Sublime Text 3 is using the .sublime-package zip file format to store all the default settings it's not very straightforward to edit the individual files.

Unfortunately, not all themes contain all scopes, so you'll need to play around with different ones to find one that looks good, and gives you the highlighting you're looking for. There are a number of themes that are included with Sublime Text, and many more are available through Package Control, which I highly recommend installing if you haven't already. Make sure you follow the ST3 directions.

As it so happens, I've developed the Neon Color Scheme, available through Package Control, that you might want to take a look at. My main goal, besides trying to make a broad range of languages look as good as possible, was to identify as many different scopes as I could - many more than are included in the standard themes. While the JavaScript language definition isn't as thorough as Python's, for example, Neon still has a lot more diversity than some of the defaults like Monokai or Solarized.

I should note that I used @int3h's Better JavaScript language definition for this image instead of the one that ships with Sublime. It can be installed via Package Control.

UPDATE

Of late I've discovered another JavaScript replacement language definition - JavaScriptNext - ES6 Syntax. It has more scopes than the base JavaScript or even Better JavaScript. It looks like this on the same code:

Also, since I originally wrote this answer, @skuroda has released PackageResourceViewer via Package Control. It allows you to seamlessly view, edit and/or extract parts of or entire .sublime-package packages. So, if you choose, you can directly edit the color schemes included with Sublime.

ANOTHER UPDATE

With the release of nearly all of the default packages on Github, changes have been coming fast and furiously. The old JS syntax has been completely rewritten to include the best parts of JavaScript Next ES6 Syntax, and now is as fully ES6-compatible as can be. A ton of other changes have been made to cover corner and edge cases, improve consistency, and just overall make it better. The new syntax has been included in the (at this time) latest dev build 3111.

If you'd like to use any of the new syntaxes with the current beta build 3103, simply clone the Github repo someplace and link the JavaScript (or whatever language(s) you want) into your Packages directory - find it on your system by selecting Preferences -> Browse Packages.... Then, simply do a git pull in the original repo directory from time to time to refresh any changes, and you can enjoy the latest and greatest! I should note that the repo uses the new .sublime-syntax format instead of the old .tmLanguage one, so they will not work with ST3 builds prior to 3084, or with ST2 (in both cases, you should have upgraded to the latest beta or dev build anyway).

I'm currently tweaking my Neon Color Scheme to handle all of the new scopes in the new JS syntax, but most should be covered already.

In general Value Objects should be Immutable. Like Integer or String objects in Java. We can use them for transferring data between software layers. If the software layers or services running in different remote nodes like in a microservices environment or in a legacy Java Enterprise App. We must make almost exact copies of two classes. This is the where we met DTOs.

|-----------|                                                   |--------------|
| SERVICE 1 |--> Credentials DTO >--------> Credentials DTO >-- | AUTH SERVICE |
|-----------|                                                   |--------------|

In legacy Java Enterprise Systems DTOs can have various EJB stuff in it.

I do not know this is a best practice or not but I personally use Value Objects in my Spring MVC/Boot Projects like this:

        |------------|         |------------------|                             |------------|
-> Form |            | -> Form |                  | -> Entity                   |            |
        | Controller |         | Service / Facade |                             | Repository |
<- View |            | <- View |                  | <- Entity / Projection View |            |
        |------------|         |------------------|                             |------------|

Controller layer doesn't know what are the entities are. It communicates with Form and View Value Objects. Form Objects has JSR 303 Validation annotations (for instance @NotNull) and View Value Objects have Jackson Annotations for custom serialization. (for instance @JsonIgnore)

Service layer communicates with repository layer via using Entity Objects. Entity objects have JPA/Hibernate/Spring Data annotations on it. Every layer communicates with only the lower layer. The inter-layer communication is prohibited because of circular/cyclic dependency.

User Service ----> XX CANNOT CALL XX ----> Order Service

Some ORM Frameworks have the ability of projection via using additional interfaces or classes. So repositories can return View objects directly. There for you do not need an additional transformation.

For instance this is our User entity:

@Entity
public final class User {
    private String id;
    private String firstname;
    private String lastname;
    private String phone;
    private String fax;
    private String address;
    // Accessors ...
}

But you should return a Paginated list of users that just include id, firstname, lastname. Then you can create a View Value Object for ORM projection.

public final class UserListItemView {
    private String id;
    private String firstname;
    private String lastname;
    // Accessors ...
}

You can easily get the paginated result from repository layer. Thanks to spring you can also use just interfaces for projections.

List<UserListItemView> find(Pageable pageable);

Don't worry for other conversion operations BeanUtils.copy method works just fine.

There seems to be a lot of bad practice being thrown around Event Handler Attributes. Bad practice is not knowing and using available features where it is most appropriate. The Event Attributes are fully W3C Documented standards and there is nothing bad practice about them. It's no different than placing inline styles, which is also W3C Documented and can be useful in times. Whether you place it wrapped in script tags or not, it's gonna be interpreted the same way.

https://www.w3.org/TR/html5/webappapis.html#event-handler-idl-attributes

You may try this :

string s = "";

foreach(DataRowView drv in checkedListBox1.CheckedItems)
{
    s += drv[0].ToString()+",";
}
s=s.TrimEnd(',');

"Simple XML Serialization" Project

You may want to look at the Simple XML Serialization project. It is the closest thing I've found to the System.Xml.Serialization in .Net.

If you don't have too many files that have changed, this will leave you with no extra commits.

1. Duplicate branch temporarily
$ git checkout -b temp_branch

2. Reset to last wanted commit
$ git reset --hard HEAD~n, where n is the number of commits you need to go back

3. Checkout each file from original branch
$ git checkout origin/original_branch filename.ext

Now you can commit and force push (to overwrite remote), if needed.

You can create your own extention method if you plan to use this a lot.

public static class StringExt
{
    public static bool ContainsInvariant(this string sourceString, string filter)
    {
        return sourceString.ToLowerInvariant().Contains(filter);
    }
}

example usage:

public class test
{
    public bool Foo()
    {
        const string def = "aB";
        return def.ContainsInvariant("s");
    }
}

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

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

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

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

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

Your options:

a) live with the occasional omissions.

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

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

For modern docker engines use this command :

docker inspect -f '{{range .NetworkSettings.Networks}}{{.IPAddress}}{{end}}' container_name_or_id

and for older engines use :

docker inspect --format '{{ .NetworkSettings.IPAddress }}' container_name_or_id

Just use JSON.stringify(object). It's built into Javascript and can therefore also be used within Typescript.

R doesn't have a concept of increment operator (as for example ++ in C). However, it is not difficult to implement one yourself, for example:

inc <- function(x)
{
 eval.parent(substitute(x <- x + 1))
}

In that case you would call

x <- 10
inc(x)

However, it introduces function call overhead, so it's slower than typing x <- x + 1 yourself. If I'm not mistaken increment operator was introduced to make job for compiler easier, as it could convert the code to those machine language instructions directly.

Use regular expression no need to convert it to char array

if(Regex.IsMatch("yourString",".*?[a-zA-Z].*?"))
{
errorCounter++;
}

Necromancing.
Also, the method by bzlm can be used to remove characters that are not in an arbitrary charset, not just ASCII:

);

System.Console.WriteLine(asAscii);

AND for those that just want to remote the accents:
(caution, because Normalize != Latinize != Romanize)

// string str = Latinize("(æøå âôû?aè");
public static string Latinize(string stIn)
{
    // Special treatment for German Umlauts
    stIn = stIn.Replace("ä", "ae");
    stIn = stIn.Replace("ö", "oe");
    stIn = stIn.Replace("ü", "ue");

    stIn = stIn.Replace("Ä", "Ae");
    stIn = stIn.Replace("Ö", "Oe");
    stIn = stIn.Replace("Ü", "Ue");
    // End special treatment for German Umlauts

    string stFormD = stIn.Normalize(System.Text.NormalizationForm.FormD);
    System.Text.StringBuilder sb = new System.Text.StringBuilder();

    for (int ich = 0; ich < stFormD.Length; ich++)
    {
        System.Globalization.UnicodeCategory uc = System.Globalization.CharUnicodeInfo.GetUnicodeCategory(stFormD[ich]);

        if (uc != System.Globalization.UnicodeCategory.NonSpacingMark)
        {
            sb.Append(stFormD[ich]);
        } // End if (uc != System.Globalization.UnicodeCategory.NonSpacingMark)

    } // Next ich


    //return (sb.ToString().Normalize(System.Text.NormalizationForm.FormC));
    return (sb.ToString().Normalize(System.Text.NormalizationForm.FormKC));
} // End Function Latinize

This is an issue with the jdbc Driver version. I had this issue when I was using mysql-connector-java-commercial-5.0.3-bin.jar but when I changed to a later driver version mysql-connector-java-5.1.22.jar, the issue was fixed.

The whole "named anchor" concept uses the name attribute, by definition. You should just stick to using the name, but the ID attribute might be handy for some javascript situations.

As in the comments, you could always use both to hedge your bets.

OS : Win10, Visual Studio 2015

Solution : Go to control panel ---> uninstall program ---MSvisual studio ----> change ---->organize = repair

and repair it. Note that you must connect to internet until repairing finish.

Good luck.

I see the many types of uses, but I find this layout more useful as a reference tool:

SELECT DATE_FORMAT('2004-01-20' ,'%Y-%m-01');

A virtual function makes its class a polymorphic base class. Derived classes can override virtual functions. Virtual functions called through base class pointers/references will be resolved at run-time. That is, the dynamic type of the object is used instead of its static type:

 Derived d;
 Base& rb = d;
 // if Base::f() is virtual and Derived overrides it, Derived::f() will be called
 rb.f();  

A pure virtual function is a virtual function whose declaration ends in =0:

class Base {
  // ...
  virtual void f() = 0;
  // ...

A pure virtual function implicitly makes the class it is defined for abstract (unlike in Java where you have a keyword to explicitly declare the class abstract). Abstract classes cannot be instantiated. Derived classes need to override/implement all inherited pure virtual functions. If they do not, they too will become abstract.

An interesting 'feature' of C++ is that a class can define a pure virtual function that has an implementation. (What that's good for is debatable.)

Note that C++11 brought a new use for the delete and default keywords which looks similar to the syntax of pure virtual functions:

my_class(my_class const &) = delete;
my_class& operator=(const my_class&) = default;

See this question and this one for more info on this use of delete and default.

NomeN has answered correctly, but this answer wouldn't be of much use for beginners like me because we will have another problem to solve and we wouldn't know how to use RegEx in there. So I am adding a bit of explanation to this. The answer is

search: (\w+\\.someMethod\\(\\))

replace: ((TypeName)$1)

Here:

In search:

• First and last (, ) depicts a group in regex

• \w depicts words (alphanumeric + underscore)

• + depicts one or more (ie one or more of alphanumeric + underscore)

• . is a special character which depicts any character (ie .+ means one or more of any character). Because this is a special character to depict a . we should give an escape character with it, ie \.

• someMethod is given as it is to be searched.

• The two parenthesis (, ) are given along with escape character because they are special character which are used to depict a group (we will discuss about group in next point)

In replace:

• It is given ((TypeName)$1), here $1 depicts the group. That is all the characters that are enclosed within the first and last parenthesis (, ) in the search field

• Also make sure you have checked the 'Regular expression' option in find an replace box

The "JavaScript" way:

var lang = navigator.language || navigator.userLanguage; //no ?s necessary

Really you should be doing language detection on the server, but if it's absolutely necessary to know/use via JavaScript, it can be gotten.

When you call setAdapter, that does not immediately lay out and position items on the screen (that takes a single layout pass) hence your scrollToPosition() call has no actual elements to scroll to when you call it.

Instead, you should register a ViewTreeObserver.OnGlobalLayoutListener (via addOnGlobalLayoutListner() from a ViewTreeObserver created by conversationView.getViewTreeObserver()) which delays your scrollToPosition() until after the first layout pass:

conversationView.getViewTreeObserver().addOnGlobalLayoutListener(new ViewTreeObserver.OnGlobalLayoutListener() {
  public void onGlobalLayout() {
    conversationView.scrollToPosition(GENERIC_MESSAGE_LIST.size();
    // Unregister the listener to only call scrollToPosition once
    conversationView.getViewTreeObserver().removeGlobalOnLayoutListener(this);

    // Use vto.removeOnGlobalLayoutListener(this) on API16+ devices as 
    // removeGlobalOnLayoutListener is deprecated.
    // They do the same thing, just a rename so your choice.
  }
});

a PK will become a clustered index unless you specify non clustered

var json = jQuery.parseJSON(s); //If you have jQuery.

Since the comment looks cluttered, please use the parse function after enclosing those square brackets inside the quotes.

var s=['{"Select":"11","PhotoCount":"12"}','{"Select":"21","PhotoCount":"22"}'];

Change the above code to

var s='[{"Select":"11","PhotoCount":"12"},{"Select":"21","PhotoCount":"22"}]';

Eg:

$(document).ready(function() {
    var s= '[{"Select":"11","PhotoCount":"12"},{"Select":"21","PhotoCount":"22"}]';

    s = jQuery.parseJSON(s);

    alert( s[0]["Select"] );
});

And then use the parse function. It'll surely work.

EDIT :Extremely sorry that I gave the wrong function name. it's jQuery.parseJSON

Jquery

The json api

Edit (30 April 2020):

Editing since I got an upvote for this answer. There's a browser native function available instead of JQuery (for nonJQuery users), JSON.parse("<json string here>")

Or you can just initialize inline in the controller. If you use an init function internal to the controller, it doesn't need to be defined in the scope. In fact, it can be self executing:

function MyCtrl($scope) {
    $scope.isSaving = false;

    (function() {  // init
        if (true) { // $routeParams.Id) {
            //get an existing object
        } else {
            //create a new object
        }
    })()

    $scope.isClean = function () {
       return $scope.hasChanges() && !$scope.isSaving;
    }

    $scope.hasChanges = function() { return false }
}

It's not too hard. Firstly, take a look at FileReader Interface.

So, when the form is submitted, catch the submission process and

var file = document.getElementById('fileBox').files[0]; //Files[0] = 1st file
var reader = new FileReader();
reader.readAsText(file, 'UTF-8');
reader.onload = shipOff;
//reader.onloadstart = ...
//reader.onprogress = ... <-- Allows you to update a progress bar.
//reader.onabort = ...
//reader.onerror = ...
//reader.onloadend = ...


function shipOff(event) {
    var result = event.target.result;
    var fileName = document.getElementById('fileBox').files[0].name; //Should be 'picture.jpg'
    $.post('/myscript.php', { data: result, name: fileName }, continueSubmission);
}

Then, on the server side (i.e. myscript.php):

$data = $_POST['data'];
$fileName = $_POST['name'];
$serverFile = time().$fileName;
$fp = fopen('/uploads/'.$serverFile,'w'); //Prepends timestamp to prevent overwriting
fwrite($fp, $data);
fclose($fp);
$returnData = array( "serverFile" => $serverFile );
echo json_encode($returnData);

Or something like it. I may be mistaken (and if I am, please, correct me), but this should store the file as something like 1287916771myPicture.jpg in /uploads/ on your server, and respond with a JSON variable (to a continueSubmission() function) containing the fileName on the server.

Check out fwrite() and jQuery.post().

On the above page it details how to use readAsBinaryString(), readAsDataUrl(), and readAsArrayBuffer() for your other needs (e.g. images, videos, etc).

If you are using HTML 5, there is the <audio> element.

On MDN:

The audio element is used to embed sound content in an HTML or XHTML document. The audio element was added as part of HTML5.

Update:

In order to play audio in the browser in HTML versions before 5 (including XHTML), you need to use one of the many flash audio players.

Visual effect:

You certainly are able to have multiple CTEs in a single query expression. You just need to separate them with a comma. Here is an example. In the example below, there are two CTEs. One is named CategoryAndNumberOfProducts and the second is named ProductsOverTenDollars.

WITH CategoryAndNumberOfProducts (CategoryID, CategoryName, NumberOfProducts) AS
(
   SELECT
      CategoryID,
      CategoryName,
      (SELECT COUNT(1) FROM Products p
       WHERE p.CategoryID = c.CategoryID) as NumberOfProducts
   FROM Categories c
),

ProductsOverTenDollars (ProductID, CategoryID, ProductName, UnitPrice) AS
(
   SELECT
      ProductID,
      CategoryID,
      ProductName,
      UnitPrice
   FROM Products p
   WHERE UnitPrice > 10.0
)

SELECT c.CategoryName, c.NumberOfProducts,
      p.ProductName, p.UnitPrice
FROM ProductsOverTenDollars p
   INNER JOIN CategoryAndNumberOfProducts c ON
      p.CategoryID = c.CategoryID
ORDER BY ProductName

And this for clearing all controls in form like textbox, checkbox, radioButton

you can add different types you want..

private void ClearTextBoxes(Control control)
    {
        foreach (Control c in control.Controls)
        {
            if (c is TextBox)
            {
                ((TextBox)c).Clear();
            }

            if (c.HasChildren)
            {
                ClearTextBoxes(c);
            }


            if (c is CheckBox)
            {

                ((CheckBox)c).Checked = false;
            }

            if (c is RadioButton)
            {
                ((RadioButton)c).Checked = false;
            }
        }
    }

It's impossible to say without seeing your actual code. Likely the reason is a code path through your function that doesn't execute a return statement. When the code goes down that path, the function ends with no value returned, and so returns None.

Updated: It sounds like your code looks like this:

def b(self, p, data): 
    current = p 
    if current.data == data: 
        return True 
    elif current.data == 1:
        return False 
    else: 
        self.b(current.next, data)

That else clause is your None path. You need to return the value that the recursive call returns:

    else:
        return self.b(current.next, data)

BTW: using recursion for iterative programs like this is not a good idea in Python. Use iteration instead. Also, you have no clear termination condition.

Here's a blog post which explains this technique in-depth.

Pattern! The group names a (sub)pattern for later use in the regex. See the documentation here for details about how such groups are used.

You have to use System.DirectoryServices;

Here are the guts of the code

using (DirectoryEntry adsEntry = new DirectoryEntry(path, strAccountId, strPassword))
{
    using (DirectorySearcher adsSearcher = new DirectorySearcher(adsEntry))
    {
        //adsSearcher.Filter = "(&(objectClass=user)(objectCategory=person))";
        adsSearcher.Filter = "(sAMAccountName=" + strAccountId + ")";

        try
        {
            SearchResult adsSearchResult = adsSearcher.FindOne();
            bSucceeded = true;

            strAuthenticatedBy = "Active Directory";
            strError = "User has been authenticated by Active Directory.";
        }
        catch (Exception ex)
        {
            // Failed to authenticate. Most likely it is caused by unknown user
            // id or bad strPassword.
            strError = ex.Message;
        }
        finally
        {
            adsEntry.Close();
        }
    }
}

Following this Microsoft Doc:

using System;
using System.Diagnostics;
using System.Threading;
class Program
{
    static void Main(string[] args)
    {
        Stopwatch stopWatch = new Stopwatch();
        stopWatch.Start();
        Thread.Sleep(10000);
        stopWatch.Stop();
        // Get the elapsed time as a TimeSpan value.
        TimeSpan ts = stopWatch.Elapsed;

        // Format and display the TimeSpan value.
        string elapsedTime = String.Format("{0:00}:{1:00}:{2:00}.{3:00}",
            ts.Hours, ts.Minutes, ts.Seconds,
            ts.Milliseconds / 10);
        Console.WriteLine("RunTime " + elapsedTime);
    }
}

Output: RunTime 00:00:09.94

extend class to AppCompatActivity instead of Activity

If you have tried all of this and still no luck, try the detach/attach again.

How about this? /(7|8|9)\d{9}/

It starts by either looking for 7 or 8 or 9, and then followed by 9 digits.

Use array_unique().

Example:

$array = array(1, 2, 2, 3);
$array = array_unique($array); // Array is now (1, 2, 3)

Please use Like below.
<a style="cursor: pointer" **(click)="yourFunctionComponent()"** >
<i class="fa fa-dribbble fa-4x"></i>
 </a>

The above can be used so that the fa icon will be shown and also on the click function you could write your logic.

I came across this recently. Which among Proxy-Authorization and Authorization headers to set depends on the server the client is talking to. If it is a Webserver, you need to set Authorization and if it a proxy, you have to set the Proxy-Authorization header

PLOTYY allows two different y-axes. Or you might look into LayerPlot from the File Exchange. I guess I should ask if you've considered using HOLD or just rescaling the data and using regular old plot?

OLD, not what the OP was looking for: SUBPLOT allows you to break a figure window into multiple axes. Then if you want to have only one x-axis showing, or some other customization, you can manipulate each axis independently.

Got here through google because i was looking for a good way to do things on the ui thread after being inside a Task.Run call - Using the following code you can use await to get back to the UI Thread again.

I hope this helps someone.

public static class UI
{
    public static DispatcherAwaiter Thread => new DispatcherAwaiter();
}

public struct DispatcherAwaiter : INotifyCompletion
{
    public bool IsCompleted => Application.Current.Dispatcher.CheckAccess();

    public void OnCompleted(Action continuation) => Application.Current.Dispatcher.Invoke(continuation);

    public void GetResult() { }

    public DispatcherAwaiter GetAwaiter()
    {
        return this;
    }
}

Usage:

... code which is executed on the background thread...
await UI.Thread;
... code which will be run in the application dispatcher (ui thread) ...

Simple Answer: NO

Well, at least a naming convention as such encouraged by Oracle or community, no, however, basically you have to be aware of following the rules and limits for identifiers, such as indicated in MySQL documentation: https://dev.mysql.com/doc/refman/8.0/en/identifiers.html

About the naming convention you follow, I think it is ok, just the number 5 is a little bit unnecesary, I think most visual tools for managing databases offer a option for sorting column names (I use DBeaver, and it have it), so if the purpouse is having a nice visual presentation of your table you can use this option I mention.

By personal experience, I would recommed this:

• Use lower case. This almost ensures interoperability when you migrate your databases from one server to another. Sometimes the lower_case_table_names is not correctly configured and your server start throwing errors just by simply unrecognizing your camelCase or PascalCase standard (case sensitivity problem).
• Short names. Simple and clear. The most easy and fast is identify your table or columns, the better. Trust me, when you make a lot of different queries in a short amount of time is better having all simple to write (and read).
• Avoid prefixes. Unless you are using the same database for tables of different applications, don't use prefixes. This only add more verbosity to your queries. There are situations when this could be useful, for example, when you want to indentify primary keys and foreign keys, that usually table names are used as prefix for id columns.
• Use underscores for separating words. If you still want to use more than one word for naming a table, column, etc., so use underscores for separating_the_words, this helps for legibility (your eyes and your stressed brain are going to thank you).
• Be consistent. Once you have your own standard, follow it. Don´t be the person that create the rules and is the first who breaking them, that is shameful.

And what about the "Plural vs Singular" naming? Well, this is most a situation of personal preferences. In my case I try to use plural names for tables because I think a table as a collection of elements or a package containig elements, so a plural name make sense for me; and singular names for columns because I see columns as attributes that describe singularly to those table elements.

And there is your answer =) Try to break it, you can't!!!

In Android Studio your resource(images) file name cannot start with NUMERIC and It cannot contain any BIG character. To solve your problem, do as Aliyah said. Just restart your IDE. This solved my problem too.

A more reliable REST endpoint would be http://freegeoip.net/json/

Returns the ip address along with the geo-location too. Also has cross-domain requests enabled (Access-Control-Allow-Origin: *) so you don't have to code around JSONP.

Here's a more comprehensive solution to the disconnect selection, and the cancellation of some of the hot keys (such as Ctrl+a and Ctrl+c. Test: Cmd+a and Cmd+c)

(function($){

  $.fn.ctrlCmd = function(key) {

    var allowDefault = true;

    if (!$.isArray(key)) {
       key = [key];
    }

    return this.keydown(function(e) {
        for (var i = 0, l = key.length; i < l; i++) {
            if(e.keyCode === key[i].toUpperCase().charCodeAt(0) && e.metaKey) {
                allowDefault = false;
            }
        };
        return allowDefault;
    });
};


$.fn.disableSelection = function() {

    this.ctrlCmd(['a', 'c']);

    return this.attr('unselectable', 'on')
               .css({'-moz-user-select':'-moz-none',
                     '-moz-user-select':'none',
                     '-o-user-select':'none',
                     '-khtml-user-select':'none',
                     '-webkit-user-select':'none',
                     '-ms-user-select':'none',
                     'user-select':'none'})
               .bind('selectstart', false);
};

})(jQuery);

and call example:

$(':not(input,select,textarea)').disableSelection();

This could be also not enough for old versions of FireFox (I can't tell which). If all this does not work, add the following:

.on('mousedown', false)

If you need a progmatic solution this should work in jQuery:

$(".abc.xyz").css("width", 200);

Since you're dealing with values that are just supposed to be boolean anyway, just use == and convert the logical response to as.integer:

df <- data.frame(col = c("true", "true", "false"))
df
#     col
# 1  true
# 2  true
# 3 false
df$col <- as.integer(df$col == "true")
df
#   col
# 1   1
# 2   1
# 3   0

If you are eager to know how to use an OR condition in a Ruby switch case:

So, in a case statement, a , is the equivalent of || in an if statement.

case car
   when 'Maruti', 'Hyundai'
      # Code here
end

See "How A Ruby Case Statement Works And What You Can Do With It".

I used this command and it worked fine with me:

>git push -f origin master

But notice, that may delete some files you already have on the remote repo. That came in handy with me as the scenario was different; I was pushing my local project to the remote repo which was empty but the READ.ME

I'm assuming you are talking about row 5 column "sex." It could be the case that in the data2.csv file, the cell contains a space and hence is not considered empty by R.

Also, I noticed that in row 5 columns "axles" and "door", the original values read from data2.csv are string "NA". You probably want to treat those as na.strings as well. To do this,

dat2 <- read.csv("data2.csv", header=T, na.strings=c("","NA"))

EDIT:

I downloaded your data2.csv. Yes, there is a space in row 5 column "sex". So you want

na.strings=c(""," ","NA")

In Laravel 3, call path('storage').

In Laravel 4, use the storage_path() helper function.

There is also a new option now in http://vimr.org/, which looks quite promising.

You don't need the jsp:useBean to set the model if you already have a controller which prepared the model.

Just access it plain by EL:

<p>${Questions.questionPaperID}</p>
<p>${Questions.question}</p>

or by JSTL <c:out> tag if you'd like to HTML-escape the values or when you're still working on legacy Servlet 2.3 containers or older when EL wasn't supported in template text yet:

<p><c:out value="${Questions.questionPaperID}" /></p>
<p><c:out value="${Questions.question}" /></p>

See also:

• Our Servlets wiki page

Unrelated to the problem, the normal practice is by the way to start attribute name with a lowercase, like you do with normal variable names.

session.setAttribute("questions", questions);

and alter EL accordingly to use ${questions}.

Also note that you don't have any JSTL tag in your code. It's all plain JSP.

One way to deal with asynchronous work like this is to use a callback function, eg:

function firstFunction(_callback){
    // do some asynchronous work
    // and when the asynchronous stuff is complete
    _callback();    
}

function secondFunction(){
    // call first function and pass in a callback function which
    // first function runs when it has completed
    firstFunction(function() {
        console.log('huzzah, I\'m done!');
    });    
}

As per @Janaka Pushpakumara's suggestion, you can now use arrow functions to achieve the same thing. For example:

firstFunction(() => console.log('huzzah, I\'m done!'))

Update: I answered this quite some time ago, and really want to update it. While callbacks are absolutely fine, in my experience they tend to result in code that is more difficult to read and maintain. There are situations where I still use them though, such as to pass in progress events and the like as parameters. This update is just to emphasise alternatives.

Also the original question doesn't specificallty mention async, so in case anyone is confused, if your function is synchronous, it will block when called. For example:

doSomething()
// the function below will wait until doSomething completes if it is synchronous
doSomethingElse()

If though as implied the function is asynchronous, the way I tend to deal with all my asynchronous work today is with async/await. For example:

const secondFunction = async () => {
  const result = await firstFunction()
  // do something else here after firstFunction completes
}

IMO, async/await makes your code much more readable than using promises directly (most of the time). If you need to handle catching errors then use it with try/catch. Read about it more here: https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Statements/async_function .

Add the following style to your h3 elements:

word-wrap: break-word;

This will cause the long URLs in them to wrap. The default setting for word-wrap is normal, which will wrap only at a limited set of split tokens (e.g. whitespaces, hyphens), which are not present in a URL.

This is how you can do it from DB2 client.

1. Open the Command Editor and Run the select Query in the Commands Tab.

2. Open the corresponding Query Results Tab

3. Then from Menu --> Selected --> Export

what you are doing here is reading one character at a time from the input stream and assume that all the characters between " " represent a word. BUT it's unlikely to be a " " after the last word, so that's probably why it does not work:

"word1 word2 word2EOF"

Using PEAR 'Spreadsheet_Excel_Writer' and 'OLE':

Only way I could get "\n" to work was making the cell $format->setTextWrap(); and then using "\n" would work.

I combined all of the above answers and created a shell function that would suit my needs. This is from a cygwin terminal of my 2 Windows10 machines where I had a shared folder between them. I need to be able to handle the following:

• cat file.cpp | tx
• tx < file.cpp
• tx file.cpp

Where a specific filename is specified, I need to used the same filename during copy. Where input data stream has been piped thru, then i need to generate a temporary filename having the hour minute and seconds. The shared mainfolder has subfolders of the days of the week. This is for organizational purposes.

Behold, the ultimate script for my needs:

tx ()
{
  if [ $# -eq 0 ]; then
    local TMP=/tmp/tx.$(date +'%H%M%S')
    while IFS= read -r line; do
        echo "$line"
    done < /dev/stdin > $TMP
    cp $TMP //$OTHER/stargate/$(date +'%a')/
    rm -f $TMP
  else
    [ -r $1 ] && cp $1 //$OTHER/stargate/$(date +'%a')/ || echo "cannot read file"
  fi
}

If there is any way that you can see to further optimize this, I would like to know.

WARNING ABOUT SOLUTIONS:

MANY EXISTING SOLUTIONS WILL GIVE THE WRONG OUTPUT IF ROWS ARE NOT UNIQUE

If you are the only person creating tables, this may not be relevant, but several solutions will give a different number of output rows from the code in question, when one of the tables may not contain unique rows.

WARNING ABOUT PROBLEM STATEMENT:

IN WITH MULTIPLE COLUMNS DOES NOT EXIST, THINK CAREFULLY WHAT YOU WANT

When I see an in with two columns, I can imagine it to mean two things:

1. The value of column a and column b appear in the other table independently
2. The values of column a and column b appear in the other table together on the same row

Scenario 1 is fairly trivial, simply use two IN statements.

In line with most existing answers, I hereby provide an overview of mentioned and additional approaches for Scenario 2 (and a brief judgement):

EXISTS (Safe, recommended for SQL Server)

As provided by @mrdenny, EXISTS sounds exactly as what you are looking for, here is his example:

SELECT * FROM T1
WHERE EXISTS
(SELECT * FROM T2 
 WHERE T1.a=T2.a and T1.b=T2.b)

LEFT SEMI JOIN (Safe, recommended for dialects that support it)

This is a very concise way to join, but unfortunately most SQL dialects, including SQL server do not currently suppport it.

SELECT * FROM T1
LEFT SEMI JOIN T2 ON T1.a=T2.a and T1.b=T2.b

Multiple IN statements (Safe, but beware of code duplication)

As mentioned by @cataclysm using two IN statements can do the trick as well, perhaps it will even outperform the other solutions. However, what you should be very carefull with is code duplication. If you ever want to select from a different table, or change the where statement, it is an increased risk that you create inconsistencies in your logic.

Basic solution

SELECT * from T1
WHERE a IN (SELECT a FROM T2 WHERE something)
AND b IN (SELECT b FROM T2 WHERE something)

Solution without code duplication (I believe this does not work in regular SQL Server queries)

WITH mytmp AS (SELECT a, b FROM T2 WHERE something);
SELECT * from T1 
WHERE a IN (SELECT a FROM mytmp)
AND b IN (SELECT b FROM mytmp)

INNER JOIN (technically it can be made safe, but often this is not done)

The reason why I don't recommend using an inner join as a filter, is because in practice people often let duplicates in the right table cause duplicates in the left table. And then to make matters worse, they sometimes make the end result distinct whilst the left table may actually not need to be unique (or not unique in the columns you select). Futhermore it gives you the chance to actually select a column that does not exists in the left table.

SELECT T1.* FROM T1
INNER JOIN 
(SELECT DISTINCT a, b FROM T2) AS T2sub
ON T1.a=T2sub.a AND T1.b=T2sub.b

Most common mistakes:

1. Joining directly on T2, without a safe subquery. Resulting in the risk of duplication)
2. SELECT * (Guaranateed to get columns from T2)
3. SELECT c (Does not guarantee that your column comes and always will come from T1)
4. No DISTINCT or DISTINCT in the wrong place

CONCATENATION OF COLUMNS WITH SEPARATOR (Not very safe, horrible performance)

The functional problem is that if you use a separator which might occur in a column, it gets tricky to ensure that the outcome is 100% accurate. The technical problem is that this method often incurs type conversions and completely ignores indexes, resulting in possibly horrible performance. Despite these problems, I have to admit that I sometimes still use it for ad-hoc queries on small datasets.

SELECT * FROM T1
WHERE CONCAT(a,"_",b) IN 
(SELECT CONCAT(a,"_",b) FROM T2)

Note that if your columns are numeric, some SQL dialects will require you to cast them to strings first. I believe SQL server will do this automatically.

To wrap things up: As usual there are many ways to do this in SQL, using safe choices will avoid suprises and save you time and headaces in the long run.

Select all the data and use the option "Text to Columns", that will allow your data for Applying Number Formatting ERIK

int indexOf(Object o) This method returns the index in this list of the first occurrence of the specified element, or -1 if this list does not contain this element.

For me the error occurred due to my browser using a cached version of the js file containing the module. Clearing the cache and reloading the page solved the problem.

I had a similar problem. I needed to get the last version of page content translation, in other words - to get that specific record which has highest number in version column. So I select all records ordered by version and then take the first row from result (by using LIMIT clause).

SELECT *
FROM `page_contents_translations`
ORDER BY version DESC
LIMIT 1

Mainly Nexus 7 modal issue , modal was going down the screen

  .modal:before {
    content: '';
    display: inline-block;
    height: 50%; (the value was 100% for center the modal)
    vertical-align: middle;
    margin-right: -4px;
  }

I don't know of any tools, but there are two roll-your-own solutions that come to mind, both require Excel:

1. You could write some VBA code that steps through each Worksheet, Row, Column and Cell of the two Workbooks, reporting differences.

2. If you use Excel 2007, you could save the Workbooks as Open-XML (*.xlsx) format, extract the XML and diff that. The Open-XML file is essentially just a .zip file of .xml files and manifests.

You'll end up with a lot of "noise" in either case if your spreadsheets aren't structurally "close" to begin with.

This may helps:

@TargetApi(Build.VERSION_CODES.LOLLIPOP)
@Override
public WebResourceResponse shouldInterceptRequest(WebView view, WebResourceRequest request) {
    String url = request.getUrl().toString();
    WebResourceResponse response = super.shouldInterceptRequest(view, request);
    // load native js
    if (url != null && url.contains(INJECTION_TOKEN/* scheme define */)) {

        response = new WebResourceResponse(
                "text/javascript",
                "utf-8",
                loadJsInputStream(url, JsCache.getJsFilePath(path) /* InputStream */));
    }
    return response;
}

Here you can see all the avaliable fontFamily values and it's corresponding font file's names(This file is using in android 5.0+). In mobile device, you can find it in:

/system/etc/fonts.xml (for 5.0+)

(For android 4.4 and below using this version, but I think that fonts.xml has a more clear format and easy to understand.)

For example,

    <!-- first font is default -->
20    <family name="sans-serif">
21        <font weight="100" style="normal">Roboto-Thin.ttf</font>
22        <font weight="100" style="italic">Roboto-ThinItalic.ttf</font>
23        <font weight="300" style="normal">Roboto-Light.ttf</font>
24        <font weight="300" style="italic">Roboto-LightItalic.ttf</font>
25        <font weight="400" style="normal">Roboto-Regular.ttf</font>
26        <font weight="400" style="italic">Roboto-Italic.ttf</font>
27        <font weight="500" style="normal">Roboto-Medium.ttf</font>
28        <font weight="500" style="italic">Roboto-MediumItalic.ttf</font>
29        <font weight="900" style="normal">Roboto-Black.ttf</font>
30        <font weight="900" style="italic">Roboto-BlackItalic.ttf</font>
31        <font weight="700" style="normal">Roboto-Bold.ttf</font>
32        <font weight="700" style="italic">Roboto-BoldItalic.ttf</font>
33    </family>

The name attribute name="sans-serif" of family tag defined the value you can use in android:fontFamily.

The font tag define the corresponded font files.

In this case, you can ignore the source under <!-- fallback fonts -->, it's using for fonts' fallback logic.

I moved my htdocs folder from C:\xampp\htdocs to D:\htdocs without editing the Apache config file (httpd.conf).

Step 3) Done!

That's the non-null assertion operator. It is a way to tell the compiler "this expression cannot be null or undefined here, so don't complain about the possibility of it being null or undefined." Sometimes the type checker is unable to make that determination itself.

It is explained here:

A new ! post-fix expression operator may be used to assert that its operand is non-null and non-undefined in contexts where the type checker is unable to conclude that fact. Specifically, the operation x! produces a value of the type of x with null and undefined excluded. Similar to type assertions of the forms <T>x and x as T, the ! non-null assertion operator is simply removed in the emitted JavaScript code.

I find the use of the term "assert" a bit misleading in that explanation. It is "assert" in the sense that the developer is asserting it, not in the sense that a test is going to be performed. The last line indeed indicates that it results in no JavaScript code being emitted.

If you're using getApplicationContext() as Context in Activity for the dialog like this

Dialog dialog = new Dialog(getApplicationContext());

then use YourActivityName.this

Dialog dialog = new Dialog(YourActivityName.this);

You just need to write the first query as a subquery (derived table), inside parentheses, pick an alias for it (t below) and alias the columns as well.

The DISTINCT can also be safely removed as the internal GROUP BY makes it redundant:

SELECT DATE(`date`) AS `date` , COUNT(`player_name`) AS `player_count`
FROM (
    SELECT MIN(`date`) AS `date`, `player_name`
    FROM `player_playtime`
    GROUP BY `player_name`
) AS t
GROUP BY DATE( `date`) DESC LIMIT 60 ;

Since the COUNT is now obvious that is only counting rows of the derived table, you can replace it with COUNT(*) and further simplify the query:

SELECT t.date , COUNT(*) AS player_count
FROM (
    SELECT DATE(MIN(`date`)) AS date
    FROM player_playtime
    GROUP BY player_name
) AS t
GROUP BY t.date DESC LIMIT 60 ;

I use ui-grid - v3.0.0-rc.20 because a scrolling issue is fixed when you go full height of container. Use the ui.grid.autoResize module will dynamically auto resize the grid to fit your data. To calculate the height of your grid use the function below. The ui-if is optional to wait until your data is set before rendering.

angular.module('app',['ui.grid','ui.grid.autoResize']).controller('AppController', ['uiGridConstants', function(uiGridConstants) {_x000D_
    ..._x000D_
    _x000D_
    $scope.gridData = {_x000D_
      rowHeight: 30, // set row height, this is default size_x000D_
      ..._x000D_
    };_x000D_
  _x000D_
    ..._x000D_
_x000D_
    $scope.getTableHeight = function() {_x000D_
       var rowHeight = 30; // your row height_x000D_
       var headerHeight = 30; // your header height_x000D_
       return {_x000D_
          height: ($scope.gridData.data.length * rowHeight + headerHeight) + "px"_x000D_
       };_x000D_
    };_x000D_
      _x000D_
    ...

<div ui-if="gridData.data.length>0" id="grid1" ui-grid="gridData" class="grid" ui-grid-auto-resize ng-style="getTableHeight()"></div>

You can invoke methods of a class instance using reflection, doing a dynamic method invocation:

Suppose that you have a method called hello in a the actual instance (this):

string methodName = "hello";

//Get the method information using the method info class
 MethodInfo mi = this.GetType().GetMethod(methodName);

//Invoke the method
// (null- no parameter for the method call
// or you can pass the array of parameters...)
mi.Invoke(this, null);

Why not doing it in two lines?

var a, b, c, d;    // All in the same scope
a = b = c = d = 1; // Set value to all.

The reason why, is to preserve the local scope on variable declarations, as this:

var a = b = c = d = 1;

will lead to the implicit declarations of b, c and d on the window scope.

I don't think you can. This is because if a variable is undefined (not set) in the twig template, it looks like NULL or none (in twig terms). I'm pretty sure this is to suppress bad access errors from occurring in the template.

Due to the lack of a "identity" in Twig (===) this is the best you can do

{% if var == null %}
    stuff in here
{% endif %}

Which translates to:

if ((isset($context['somethingnull']) ? $context['somethingnull'] : null) == null)
{
  echo "stuff in here";
}

Which if your good at your type juggling, means that things such as 0, '', FALSE, NULL, and an undefined var will also make that statement true.

My suggest is to ask for the identity to be implemented into Twig.

In the DOM, the class of an element is just each class separated by a space. You would just need to implement the parsing logic to insert / remove the classes as necesary.

I wonder though... why wouldn't you want to use jQuery? It makes this kind of problem trivially easy.

Using only Javas own API:

String[] join(String[]... arrays) {
  // calculate size of target array
  int size = 0;
  for (String[] array : arrays) {
    size += array.length;
  }

  // create list of appropriate size
  java.util.List list = new java.util.ArrayList(size);

  // add arrays
  for (String[] array : arrays) {
    list.addAll(java.util.Arrays.asList(array));
  }

  // create and return final array
  return list.toArray(new String[size]);
}

Now, this code ist not the most efficient, but it relies only on standard java classes and is easy to understand. It works for any number of String[] (even zero arrays).

The following will do.

string datestring = DateTime.Now.ToString("yyyy-MM-dd", CultureInfo.InvariantCulture);

Here's a good option for doing this:

public static <T> T getSingleResult(TypedQuery<T> query) {
    query.setMaxResults(1);
    List<T> list = query.getResultList();
    if (list == null || list.isEmpty()) {
        return null;
    }

    return list.get(0);
}

I agree with Simon Sarris's conclusions:

I have compared some visualization in Protovis (SVG) to Processingjs (Canvas) which display > 2000 points and processingjs is much faster than protovis.

Handling events with SVG is of course much easer because you can attach them to the objects. In Canvas you have to do it manually (check mouse position, etc) but for simple interaction it shouldn't be hard.

There is also the dojo.gfx library of the dojo toolkit. It provides an abstraction layer and you can specify the renderer (SVG, Canvas, Silverlight). That might be also an viable choice although I don't know how much overhead the additional abstraction layer adds but it makes it easy to code interactions and animations and is renderer-agnostic.

Here are some interesting benchmarks:

• http://svbreakaway.info/tp.php#jan21a
• http://www.eleqtriq.com/2010/02/canvas-svg-flash/
• http://smus.com/canvas-vs-svg-performance/

Decide a width and check how many characters one line could hold, and then for each key pressed you call a function that looks something like:

function changeHeight()
{
var chars_per_row = 100;
var pixles_per_row = 16;
this.style.height = Math.round((this.value.length / chars_per_row) * pixles_per_row) + 'px';
}

Havn't tested the code.

Putting a whole array into one localStorage entry is very inefficient: the whole thing needs to be re-encoded every time you add something to the array or change one entry.

An alternative is to use http://rhaboo.org which stores any JS object, however deeply nested, using a separate localStorage entry for each terminal value. Arrays are restored much more faithfully, including non-numeric properties and various types of sparseness, object prototypes/constructors are restored in standard cases and the API is ludicrously simple:

var store = Rhaboo.persistent('Some name');
store.write('count', store.count ? store.count+1 : 1);

store.write('somethingfancy', {
  one: ['man', 'went'],
  2: 'mow',
  went: [  2, { mow: ['a', 'meadow' ] }, {}  ]
});  
store.somethingfancy.went[1].mow.write(1, 'lawn');

BTW, I wrote it.

Better use Uri.IsWellFormedUriString(string uriString, UriKind uriKind). http://msdn.microsoft.com/en-us/library/system.uri.iswellformeduristring.aspx

Example :-

 if(Uri.IsWellFormedUriString(slct.Text,UriKind.Absolute))
 {
        Uri uri = new Uri(slct.Text);
        if (DeleteFileOnServer(uri))
        {
          nn.BalloonTipText = slct.Text + " has been deleted.";
          nn.ShowBalloonTip(30);
        }
 }

You can use lists comprehensions:

strip_list = [item.strip() for item in lines]

Or the map function:

# with a lambda
strip_list = map(lambda it: it.strip(), lines)

# without a lambda
strip_list = map(str.strip, lines)

How to create CascadeClassifier :

1. Open this link : https://github.com/opencv/opencv/tree/master/data/haarcascades
2. Right click on where you find "haarcascade_frontalface_default.xml"
3. Click on "Save link as"
4. Save it into the same folder in which your file is.
5. Include this line in your file face_cascade = cv2.CascadeClassifier(cv2.data.haarcascades + "haarcascade_frontalface_default.xml")

It's simple math. Given a number X and a rounding factor N, the formula would be:

round(X / N)*N

For version v2.2.2 and newer

In version v2.2.2 and up, name property no longer exists and it shouldn't be used to define the route. path should be used instead of name and no leading slash is needed on the path. In this case use path: '404' instead of path: '/404':

 {path: '404', component: NotFoundComponent},
 {path: '**', redirectTo: '/404'}

For versions older than v2.2.2

you can use {path: '/*path', redirectTo: ['redirectPathName']}:

{path: '/home/...', name: 'Home', component: HomeComponent}
{path: '/', redirectTo: ['Home']},
{path: '/user/...', name: 'User', component: UserComponent},
{path: '/404', name: 'NotFound', component: NotFoundComponent},

{path: '/*path', redirectTo: ['NotFound']}

if no path matches then redirect to NotFound path

unicode('foo,bar').translate(dict([[ord(char), u''] for char in u',']))

Your value:

this.element = $(id);

is a jQuery object, not a pure Canvas element.

To turn it back so you can call getContext(), call this.element.get(0), or better yet store the real element and not the jQuery object:

function canvasLayer(location, id) {

    this.width = $(window).width();
    this.height = $(window).height();
    this.element = document.createElement('canvas');

    $(this.element)
       .attr('id', id)
       .text('unsupported browser')
       .attr('width', this.width)       // for pixels
       .attr('height', this.height)
       .width(this.width)               // for CSS scaling
       .height(this.height)
       .appendTo(location);

    this.context = this.element.getContext("2d");
}

See running code at http://jsfiddle.net/alnitak/zbaMh/, ideally using the Chrome Javascript Console so you can see the resulting object in the debug output.

Essentially, the only thing in Python that introduces a new scope is a function definition. Classes are a bit of a special case in that anything defined directly in the body is placed in the class's namespace, but they are not directly accessible from within the methods (or nested classes) they contain.

In your example there are only 3 scopes where x will be searched in:

• spam's scope - containing everything defined in code3 and code5 (as well as code4, your loop variable)

• The global scope - containing everything defined in code1, as well as Foo (and whatever changes after it)

• The builtins namespace. A bit of a special case - this contains the various Python builtin functions and types such as len() and str(). Generally this shouldn't be modified by any user code, so expect it to contain the standard functions and nothing else.

More scopes only appear when you introduce a nested function (or lambda) into the picture. These will behave pretty much as you'd expect however. The nested function can access everything in the local scope, as well as anything in the enclosing function's scope. eg.

def foo():
    x=4
    def bar():
        print x  # Accesses x from foo's scope
    bar()  # Prints 4
    x=5
    bar()  # Prints 5

Restrictions:

Variables in scopes other than the local function's variables can be accessed, but can't be rebound to new parameters without further syntax. Instead, assignment will create a new local variable instead of affecting the variable in the parent scope. For example:

global_var1 = []
global_var2 = 1

def func():
    # This is OK: It's just accessing, not rebinding
    global_var1.append(4) 

    # This won't affect global_var2. Instead it creates a new variable
    global_var2 = 2 

    local1 = 4
    def embedded_func():
        # Again, this doen't affect func's local1 variable.  It creates a 
        # new local variable also called local1 instead.
        local1 = 5
        print local1

    embedded_func() # Prints 5
    print local1    # Prints 4

In order to actually modify the bindings of global variables from within a function scope, you need to specify that the variable is global with the global keyword. Eg:

global_var = 4
def change_global():
    global global_var
    global_var = global_var + 1

Currently there is no way to do the same for variables in enclosing function scopes, but Python 3 introduces a new keyword, "nonlocal" which will act in a similar way to global, but for nested function scopes.

Both answers are wrong. You can. You need to call

$.ajaxSetup({
async: false
});

before your json ajax call. And you can set it to true after call retuns ( if there are other usages of ajax on page if you want them async )

100 characters.

This is the var (variable) in varchar: you only store what you enter (and an extra 2 bytes to store length upto 65535)

If it was char(200) then you'd always store 200 characters, padded with 100 spaces

See the docs: "The CHAR and VARCHAR Types"

You don't really need the directive, can achieve it by using the ng-init and ng-checked. below demo link shows how to set the initial value for checkbox in angularjs.

Not completely clear what you mean. Perhaps:

<script type="text/javascript"> 
$(document).ready(function() {
  $("a").click(function() {
    var params = {};
    params['pageNo'] = $(this).text();
    params['sortBy'] = $("#sortBy").val();
    $("#results").load( "jquery-routing.php", params );
    return false;
  });
}); 
</script>
