Mount a "volume" and copy the artifacts into there:

mkdir artifacts
docker run -i -v ${PWD}/artifacts:/artifacts ubuntu:14.04 sh << COMMANDS
# ... build software here ...
cp <artifact> /artifacts
# ... copy more artifacts into `/artifacts` ...
COMMANDS

Then when the build finishes and the container is no longer running, it has already copied the artifacts from the build into the artifacts directory on the host.

Edit

Caveat: When you do this, you may run into problems with the user id of the docker user matching the user id of the current running user. That is, the files in /artifacts will be shown as owned by the user with the UID of the user used inside the docker container. A way around this may be to use the calling user's UID:

docker run -i -v ${PWD}:/working_dir -w /working_dir -u $(id -u) \
    ubuntu:14.04 sh << COMMANDS
# Since $(id -u) owns /working_dir, you should be okay running commands here
# and having them work. Then copy stuff into /working_dir/artifacts .
COMMANDS

MongoDB has a simple web based administrative port at 28017 by default.

There is no HTTP access at the default port of 27017 (which is what the error message is trying to suggest). The default port is used for native driver access, not HTTP traffic.

To access MongoDB, you'll need to use a driver like the MongoDB native driver for NodeJS. You won't "POST" to MongoDB directly (but you might create a RESTful API using express which uses the native drivers). Instead, you'll use a wrapper library that makes accessing MongoDB convenient. You might also consider using Mongoose (which uses the native driver) which adds an ORM-like model for MongoDB in NodeJS.

If you can't get to the web interface, it may be disabled. Normally, I wouldn't expect that you'd need it for doing development unless you're checking logs and such.

For Ubuntu users: First You need to install mailutils

sudo apt-get install mailutils

Setup an email server, if you are using gmail or smtp. follow this link. then use this command to send email.

echo "this is a test mail" | mail -s "Subject of mail" [email protected]

In case you are using gmail and still you are getting some authentication error then you need to change setting of gmail:

Turn on Access for less secure apps from here

This is exactly what the in operator is for. Use it like this:

if (index in currentData) 
{ 
    Ti.API.info(index + " exists: " + currentData[index]);
}

The accepted answer is wrong, it will give a false negative if the value at index is undefined:

const currentData = ['a', undefined], index = 1;_x000D_
_x000D_
if (index in currentData) {_x000D_
  console.info('exists');_x000D_
}_x000D_
// ...vs..._x000D_
if (typeof currentData[index] !== 'undefined') {_x000D_
  console.info('exists');_x000D_
} else {_x000D_
  console.info('does not exist'); // incorrect!_x000D_
}

The initialize method is called after all @FXML annotated members have been injected. Suppose you have a table view you want to populate with data:

class MyController { 
    @FXML
    TableView<MyModel> tableView; 

    public MyController() {
        tableView.getItems().addAll(getDataFromSource()); // results in NullPointerException, as tableView is null at this point. 
    }

    @FXML
    public void initialize() {
        tableView.getItems().addAll(getDataFromSource()); // Perfectly Ok here, as FXMLLoader already populated all @FXML annotated members. 
    }
}

The JWT aud (Audience) Claim

According to RFC 7519:

The "aud" (audience) claim identifies the recipients that the JWT is intended for. Each principal intended to process the JWT MUST identify itself with a value in the audience claim. If the principal processing the claim does not identify itself with a value in the "aud" claim when this claim is present, then the JWT MUST be rejected. In the general case, the "aud" value is an array of case- sensitive strings, each containing a StringOrURI value. In the special case when the JWT has one audience, the "aud" value MAY be a single case-sensitive string containing a StringOrURI value. The interpretation of audience values is generally application specific. Use of this claim is OPTIONAL.

The Audience (aud) claim as defined by the spec is generic, and is application specific. The intended use is to identify intended recipients of the token. What a recipient means is application specific. An audience value is either a list of strings, or it can be a single string if there is only one aud claim. The creator of the token does not enforce that aud is validated correctly, the responsibility is the recipient's to determine whether the token should be used.

Whatever the value is, when a recipient is validating the JWT and it wishes to validate that the token was intended to be used for its purposes, it MUST determine what value in aud identifies itself, and the token should only validate if the recipient's declared ID is present in the aud claim. It does not matter if this is a URL or some other application specific string. For example, if my system decides to identify itself in aud with the string: api3.app.com, then it should only accept the JWT if the aud claim contains api3.app.com in its list of audience values.

Of course, recipients may choose to disregard aud, so this is only useful if a recipient would like positive validation that the token was created for it specifically.

My interpretation based on the specification is that the aud claim is useful to create purpose-built JWTs that are only valid for certain purposes. For one system, this may mean you would like a token to be valid for some features but not for others. You could issue tokens that are restricted to only a certain "audience", while still using the same keys and validation algorithm.

Since in the typical case a JWT is generated by a trusted service, and used by other trusted systems (systems which do not want to use invalid tokens), these systems simply need to coordinate the values they will be using.

Of course, aud is completely optional and can be ignored if your use case doesn't warrant it. If you don't want to restrict tokens to being used by specific audiences, or none of your systems actually will validate the aud token, then it is useless.

Example: Access vs. Refresh Tokens

One contrived (yet simple) example I can think of is perhaps we want to use JWTs for access and refresh tokens without having to implement separate encryption keys and algorithms, but simply want to ensure that access tokens will not validate as refresh tokens, or vice-versa.

By using aud, we can specify a claim of refresh for refresh tokens and a claim of access for access tokens upon creating these tokens. When a request is made to get a new access token from a refresh token, we need to validate that the refresh token was a genuine refresh token. The aud validation as described above will tell us whether the token was actually a valid refresh token by looking specifically for a claim of refresh in aud.

OAuth Client ID vs. JWT aud Claim

The OAuth Client ID is completely unrelated, and has no direct correlation to JWT aud claims. From the perspective of OAuth, the tokens are opaque objects.

The application which accepts these tokens is responsible for parsing and validating the meaning of these tokens. I don't see much value in specifying OAuth Client ID within a JWT aud claim.

Try this code:

imgView.setImageResource(android.R.color.transparent); 

also this one works:

imgView.setImageResource(0); 

but be careful this one doesn't work:

imgView.setImageResource(null); 

var isOdd = x => Boolean(x % 2);
var isEven = x => !isOdd(x);

A little late but I wanted to add the solution I used to solve this problem. I found the solution here.

Anyway, the question seems to be asking 'how to start a new project from a branch of another repo?'

To this, the solution I used would be to first create a new repo in github or where ever. This will serve as the repo to your new project.

On your local machine, navigate to the project that has the branch you want to use as the template for your new project.

Run the command:

git push https://github.com/accountname/new-repo.git +old_branch:master

What this will do is push the old_branch to new-repo and make it the master branch of the new repo.

You then just have to clone the new repo down to your new project's local directory and you have a new project started at the old branch.

Blobs are returned with file type from backend. The following function will accept any file type and popup download window:

downloadFile(route: string, filename: string = null): void{

    const baseUrl = 'http://myserver/index.php/api';
    const token = 'my JWT';
    const headers = new HttpHeaders().set('authorization','Bearer '+token);
    this.http.get(baseUrl + route,{headers, responseType: 'blob' as 'json'}).subscribe(
        (response: any) =>{
            let dataType = response.type;
            let binaryData = [];
            binaryData.push(response);
            let downloadLink = document.createElement('a');
            downloadLink.href = window.URL.createObjectURL(new Blob(binaryData, {type: dataType}));
            if (filename)
                downloadLink.setAttribute('download', filename);
            document.body.appendChild(downloadLink);
            downloadLink.click();
        }
    )
}

Here I came up with universal method to navigate from any place to root.

1. You create a new Class file with this class, so that it's accessible from anywhere in your project:

   import UIKit
   
   class SharedControllers
   {
       static func navigateToRoot(viewController: UIViewController)
       {
           var nc = viewController.navigationController
   
           // If this is a normal view with NavigationController, then we just pop to root.
           if nc != nil
           {
               nc?.popToRootViewControllerAnimated(true)
               return
           }
   
           // Most likely we are in Modal view, so we will need to search for a view with NavigationController.
           let vc = viewController.presentingViewController
   
           if nc == nil
           {
               nc = viewController.presentingViewController?.navigationController
           }
   
           if nc == nil
           {
               nc = viewController.parentViewController?.navigationController
           }
   
           if vc is UINavigationController && nc == nil
           {
               nc = vc as? UINavigationController
           }
   
           if nc != nil
           {
               viewController.dismissViewControllerAnimated(false, completion:
                   {
                       nc?.popToRootViewControllerAnimated(true)
               })
           }
       }
   }
   

2. Usage from anywhere in your project:

   {
       ...
       SharedControllers.navigateToRoot(self)
       ...
   }
   

You can try the hashdiff gem, which allows deep comparison of hashes and arrays in the hash.

The following is an example:

a = {a:{x:2, y:3, z:4}, b:{x:3, z:45}}
b = {a:{y:3}, b:{y:3, z:30}}

diff = HashDiff.diff(a, b)
diff.should == [['-', 'a.x', 2], ['-', 'a.z', 4], ['-', 'b.x', 3], ['~', 'b.z', 45, 30], ['+', 'b.y', 3]]

"this" extends the next class in the parameter list

So in the method signature below "this" extends "String". Line is passed to the function as a normal argument to the method. public static string[] SplitCsvLine(this String line)

In the above example "this" class is extending the built in "String" class.

You could use a Bash C Style For Loop to do what you want.

my_array=(one two three)

for ((i=0; i < ${#my_array[@]}; i++ )); do echo "${my_array[$i]}"; done
one
two
three

Here's a simple function:

CREATE FUNCTION fn_which_edition
        RETURN VARCHAR2
    IS

        Person      Date        Comments
        ---------   ------      -------------------------------------------
        dcox        6/6/2013    Initial Build

    */

    -- Banner
    CURSOR c_get_banner
    IS
        SELECT banner
          FROM v$version
         WHERE UPPER(banner) LIKE UPPER('Oracle Database%');

    vrec_banner c_get_banner%ROWTYPE; -- row record
    v_database VARCHAR2(32767); --

BEGIN
    -- Get banner to get edition
    OPEN c_get_banner;
    FETCH c_get_banner INTO vrec_banner;
    CLOSE c_get_banner;

    -- Check for Database type
    IF INSTR( UPPER(vrec_banner.banner), 'EXPRESS') > 0
    THEN
        v_database := 'EXPRESS';
    ELSIF INSTR( UPPER(vrec_banner.banner), 'STANDARD') > 0
    THEN
        v_database := 'STANDARD';
    ELSIF INSTR( UPPER(vrec_banner.banner), 'PERSONAL') > 0
    THEN
        v_database := 'PERSONAL';
    ELSIF INSTR( UPPER(vrec_banner.banner), 'ENTERPRISE') > 0
    THEN
        v_database := 'ENTERPRISE';
    ELSE
        v_database := 'UNKNOWN';
    END IF;

    RETURN v_database;
EXCEPTION
    WHEN OTHERS
    THEN
        RETURN 'ERROR:' || SQLERRM(SQLCODE);
END fn_which_edition; -- function fn_which_edition
/

Done.

I followed the below Steps. It worked for me.

In Jenkins execute shell under Build, creating a file and trying to push that file from Jenkins workspace to GitHub.

Download Git Publisher Plugin and Configure as shown below snapshot.

Click on Save and Build. Now you can check your git repository whether the file was pushed successfully or not.

Well here is the short method to check whether the string is empty or not.

$input; //Assuming to be the string


if(strlen($input)==0){
return false;//if the string is empty
}
else{
return true; //if the string is not empty
}

If you are defining UICollectionViewFlowLayout in code, it will override Interface Builder configs. Hence you need to re-define the scrollDirection again.

let layout = UICollectionViewFlowLayout()
...
layout.scrollDirection = .Horizontal
self.awesomeCollectionView.collectionViewLayout = layout

This might work:

git checkout 56e05f
echo ref: refs/heads/master > .git/HEAD
git commit

It works like this:

h4 {
    display:inline;
}
h4:after {
    content:"\a";
    white-space: pre;
}

Example: http://jsfiddle.net/Bb2d7/

The trick comes from here: https://stackoverflow.com/a/66000/509752 (to have more explanation)

No there isn't. You can only read information associated with the current domain.

I think there is no out-of-the-box support for that in VS Code.

You can install a plugin to give you similar functionality. Eg.:

https://marketplace.visualstudio.com/items?itemName=micnil.vscode-checkpoints

Or the more famous:

https://marketplace.visualstudio.com/items?itemName=xyz.local-history

Some details may need to be configured: The VS Code search gets confused sometimes because of additional folders created by this type of plugins. You can configure it to ignore such folders or change their locations (adding such folders to your .gitignore file also solves this problem).

Try this:

To accept theirs changes: git merge --strategy-option theirs

To accept yours: git merge --strategy-option ours

Try this using HTML like here:

var myDate = window.document.getElementById("startdate").value;

Improved @yar1vn answer by dropping string dependency:

#define VariableName(arg) (@""#arg)

typedef NS_ENUM(NSUInteger, UserType) {
    UserTypeParent = 0,
    UserTypeStudent = 1,
    UserTypeTutor = 2,
    UserTypeUnknown = NSUIntegerMax
};  

@property (nonatomic) UserType type;

+ (NSDictionary *)typeDisplayNames
{
    return @{@(UserTypeParent) : VariableName(UserTypeParent),
             @(UserTypeStudent) : VariableName(UserTypeStudent),
             @(UserTypeTutor) : VariableName(UserTypeTutor),
             @(UserTypeUnknown) : VariableName(UserTypeUnknown)};
}

- (NSString *)typeDisplayName
{
    return [[self class] typeDisplayNames][@(self.type)];
}

Thus when you'll change enum entry name corresponding string will be changed. Useful in case if you are not going to show this string to user.

I use GateOne from the synocommunity.

Go into settings in Package Center and add http://packages.synocommunity.com/ as a package source. Then you should be able to add it easily via Package Center.

Try this:

colnames(DF) = DF[1, ] # the first row will be the header
DF = DF[-1, ]          # removing the first row.

However, get a look if the data has been properly read. If you data.frame has numeric variables but the first row were characters, all the data has been read as character. To avoid this problem, it's better to save the data and read again with header=TRUE as you suggest. You can also get a look to this question: Reading a CSV file organized horizontally.

Look into xcopy, which will recursively copy files and subdirectories.

There are examples, 2/3 down the page. Of particular use is:

To copy all the files and subdirectories (including any empty subdirectories) from drive A to drive B, type:

xcopy a: b: /s /e

This is possible if you have an existing Newline character in the row or another row.

Select the square-box that represents the existing Newline character, copy it (control-C), and then paste it (control-V) where you want it to be.

This is slightly cheesy, but I actually did get it to work in SSMS 2008 and I was not able to get any of the other suggestions (control-enter, alt-13, or any alt-##) to work.

You are trying to add an integer into an ArrayList that takes an array of integers Integer[]. It should be

ArrayList<Integer> list = new ArrayList<>();

or better

List<Integer> list = new ArrayList<>();

You should write the pickled data with a lower protocol number in Python 3. Python 3 introduced a new protocol with the number 3 (and uses it as default), so switch back to a value of 2 which can be read by Python 2.

Check the protocolparameter in pickle.dump. Your resulting code will look like this.

pickle.dump(your_object, your_file, protocol=2)

There is no protocolparameter in pickle.load because pickle can determine the protocol from the file.

It'll have the same behavior as the underlying recv libc call see the man page for an official description of behavior (or read a more general description of the sockets api).

I found another method: Is necessary to add the "android:maxWidth="40dp"" attribute. Of course, it may not work perfectly, but it gives a line break.

settings.py

ALLOWED_HOSTS = ['*']

Even though this is old and answered, i´d like to share the solution i made out of it 2020

it comes with the flexibility to run at anytime and run a callback if greater and or smaller the specified mbps

you can start the test anywhere after you included the testConnectionSpeed Object by running the testConnectionSpeed.run(mbps, morefunction, lessfunction)

for example:

var testConnectionSpeed = {
  imageAddr : "https://upload.wikimedia.org/wikipedia/commons/a/a6/Brandenburger_Tor_abends.jpg", // this is just an example, you rather want an image hosted on your server
  downloadSize : 2707459, // this must match with the image above
  run:function(mbps_max,cb_gt,cb_lt){
    testConnectionSpeed.mbps_max = parseFloat(mbps_max) ? parseFloat(mbps_max) : 0;
    testConnectionSpeed.cb_gt = cb_gt;
    testConnectionSpeed.cb_lt = cb_lt;
    testConnectionSpeed.InitiateSpeedDetection();
  },
  InitiateSpeedDetection: function() {
    window.setTimeout(testConnectionSpeed.MeasureConnectionSpeed, 1);
  },
  result:function(){
    var duration = (endTime - startTime) / 1000;
    var bitsLoaded = testConnectionSpeed.downloadSize * 8;
    var speedBps = (bitsLoaded / duration).toFixed(2);
    var speedKbps = (speedBps / 1024).toFixed(2);
    var speedMbps = (speedKbps / 1024).toFixed(2);
    if(speedMbps >= (testConnectionSpeed.max_mbps ? testConnectionSpeed.max_mbps : 1) ){
      testConnectionSpeed.cb_gt ? testConnectionSpeed.cb_gt(speedMbps) : false;
    }else {
      testConnectionSpeed.cb_lt ? testConnectionSpeed.cb_lt(speedMbps) : false;
    }
  },
  MeasureConnectionSpeed:function() {
    var download = new Image();
    download.onload = function () {
        endTime = (new Date()).getTime();
        testConnectionSpeed.result();
    }
    startTime = (new Date()).getTime();
    var cacheBuster = "?nnn=" + startTime;
    download.src = testConnectionSpeed.imageAddr + cacheBuster;
  }
}




// start test immediatly, you could also call this on any event or whenever you want
testConnectionSpeed.run(1.5, function(mbps){console.log(">= 1.5Mbps ("+mbps+"Mbps)")}, function(mbps){console.log("< 1.5Mbps("+mbps+"Mbps)")} )

I used this successfuly to load lowres media for slow internet connections. You have to play around a bit because on the one hand, the larger the image, the more reasonable the test, on the other hand the test will take way much longer for slow connection and in my case I especially did not want slow connection users to load lots of MBs.

Visual Studio has multiple flags to reset various settings:

• /ResetUserData - (AFAICT) Removes all user settings and makes you set them again. This will get you the initial prompt for settings again, clear your recent project history, etc.
• /ResetSettings - Restores the IDE's default settings, optionally resets to the specified VSSettings file.
• /ResetSkipPkgs - Clears all SkipLoading tags added to VSPackages.
• /ResetAddin - Removes commands and command UI associated with the specified Add-in.

The last three show up when running devenv.exe /?. The first one seems to be undocumented/unsupported/the big hammer. From here:

Disclaimer: you will lose all your environment settings and customizations if you use this switch. It is for this reason that this switch is not officially supported and Microsoft does not advertise this switch to the public (you won't see this switch if you type devenv.exe /? in the command prompt). You should only use this switch as the last resort if you are experiencing an environment problem, and make sure you back up your environment settings by exporting them before using this switch.

For those who still have this problem, and none of the above solutions worked for you:
Update your versions of java and Eclipse.
In my case, I updated from java 7 to java 9, and Eclipse Mars to Eclipse Oxygen, and this problem was solved !!!

You have to create a derived table for the distinct columns and then query the count from that table:

SELECT COUNT(*) 
FROM (SELECT DISTINCT column1,column2
      FROM  tablename  
      WHERE condition ) as dt

Here dt is a derived table.

It appears you could use a list instead of a tuple. This becomes more important I think when you are grabbing attributes instead of 'magic indexes' of a list/tuple.

In my case I wanted to sort by multiple attributes of a class, where the incoming keys were strings. I needed different sorting in different places, and I wanted a common default sort for the parent class that clients were interacting with; only having to override the 'sorting keys' when I really 'needed to', but also in a way that I could store them as lists that the class could share

So first I defined a helper method

def attr_sort(self, attrs=['someAttributeString']:
  '''helper to sort by the attributes named by strings of attrs in order'''
  return lambda k: [ getattr(k, attr) for attr in attrs ]

then to use it

# would defined elsewhere but showing here for consiseness
self.SortListA = ['attrA', 'attrB']
self.SortListB = ['attrC', 'attrA']
records = .... #list of my objects to sort
records.sort(key=self.attr_sort(attrs=self.SortListA))
# perhaps later nearby or in another function
more_records = .... #another list
more_records.sort(key=self.attr_sort(attrs=self.SortListB))

This will use the generated lambda function sort the list by object.attrA and then object.attrB assuming object has a getter corresponding to the string names provided. And the second case would sort by object.attrC then object.attrA.

This also allows you to potentially expose outward sorting choices to be shared alike by a consumer, a unit test, or for them to perhaps tell you how they want sorting done for some operation in your api by only have to give you a list and not coupling them to your back end implementation.

Edit: I misunderstood your question, I thought you were asking how to pad with spaces.

What you are asking is not possible using the string.Format alignment component; string.Format always pads with whitespace. See the Alignment Component section of MSDN: Composite Formatting.

According to Reflector, this is the code that runs inside StringBuilder.AppendFormat(IFormatProvider, string, object[]) which is called by string.Format:

int repeatCount = num6 - str2.Length;
if (!flag && (repeatCount > 0))
{
    this.Append(' ', repeatCount);
}
this.Append(str2);
if (flag && (repeatCount > 0))
{
    this.Append(' ', repeatCount);
}

As you can see, blanks are hard coded to be filled with whitespace.

So, I went on trying everything and at last it seems that reinstalling java after uninstalling it fixed my problem.

From the manpage for env (GNU coreutils 6.10):

env - run a program in a modified environment

In theory you could use env to reset the environment (removing many of the existing environment variables) or add additional environment variables in the script header. Practically speaking, the two versions you mentioned are identical. (Though others have mentioned a good point: specifying python through env lets you abstractly specify python without knowing its path.)

It's very simple

self.navigationController?.view.semanticContentAttribute = .forceRightToLeft

Using new ES6 Object.entries(), it makes for a fun little nested map/join:

const encodeGetParams = p => _x000D_
  Object.entries(p).map(kv => kv.map(encodeURIComponent).join("=")).join("&");_x000D_
_x000D_
const params = {_x000D_
  user: "María Rodríguez",_x000D_
  awesome: true,_x000D_
  awesomeness: 64,_x000D_
  "ZOMG+&=*(": "*^%*GMOZ"_x000D_
};_x000D_
_x000D_
console.log("https://example.com/endpoint?" + encodeGetParams(params))

Since image is deprecated, you should use varbinary.

per Microsoft (thanks for the link @Christopher)

ntext , text, and image data types will be removed in a future version of Microsoft SQL Server. Avoid using these data types in new development work, and plan to modify applications that currently use them. Use nvarchar(max), varchar(max), and varbinary(max) instead.

Fixed and variable-length data types for storing large non-Unicode and Unicode character and binary data. Unicode data uses the UNICODE UCS-2 character set.

This could also be an issue of building the code using a 64 bit configuration. You can try to select x86 as the build platform which can solve this issue. To do this right-click the solution and select Configuration Manager From there you can change the Platform of the project using the 32-bit .dll to x86

Swift 3.0

Create a ViewController with the UITableViewDelegate and UITableViewDataSource protocols. Then create a tableView inside it, declaring its style to be UITableViewStyle.grouped. This will fix the headers.

lazy var tableView: UITableView = {
    let view = UITableView(frame: UIScreen.main.bounds, style: UITableViewStyle.grouped)
    view.delegate = self
    view.dataSource = self
    view.separatorStyle = .none
    return view
}()

I'd use Apache Collections Lazy Map (to initialize values to 0) and use MutableIntegers from Apache Lang as values in that map.

Biggest cost is having to serach the map twice in your method. In mine you have to do it just once. Just get the value (it will get initialized if absent) and increment it.

I have to guess here, but git is probably running its output into your $PAGER program, likely less or more. In either case, typing q should get you out.

The pattern must have delimiters. Delimiters can be a forward slash (/) or any non alphanumeric characters(#,$,*,...). Examples

$pattern = "/My name is '(.*)' and im fine/"; 
$pattern = "#My name is '(.*)' and im fine#";
$pattern = "@My name is '(.*)' and im fine@";  

rsplit should be up to the task:

In [1]: 'http://www.test.com/page/TEST2'.rsplit('/', 1)[1]
Out[1]: 'TEST2'

The getElementById() based method in the selected answer won't work if the anchor has name but not id set (which is not recommended, but does happen in the wild).

Something to bare in mind if you don't have control of the document markup (e.g. webextension).

The location based method in the selected answer can also be simplified with location.replace:

function jump(hash) { location.replace("#" + hash) }

. I usually do it element.value="<script>alert('test');</script>".

If sounds like you are generating an inline <script> element, in which case the </script> will end the HTML element and cause the script to terminate in the middle of the string.

Escape the / so that it isn't treated as an end tag by the HTML parser:

element.value = "<script>alert('test');<\/script>"

If you want to avoid including the full path to awk, you need to update your PATH variable to include the path to the directory where awk is located, then you can just type

awk

to run your programs.

Go to Control Panel->System->Advanced and set your PATH environment variable to include "C:\Program Files (x86)\GnuWin32\bin" at the end (separated by a semi-colon) from previous entry.

This function will return a converted SQL date from java date object.

public static java.sql.Date convertFromJAVADateToSQLDate(
            java.util.Date javaDate) {
        java.sql.Date sqlDate = null;
        if (javaDate != null) {
            sqlDate = new Date(javaDate.getTime());
        }
        return sqlDate;
    }

An Instant is what it says: a specific instant in time - it does not have the notion of date and time (the time in New York and Tokyo is not the same at a given instant).

To print it as a date/time, you first need to decide which timezone to use. For example:

System.out.println(LocalDateTime.ofInstant(i, ZoneOffset.UTC));

This will print the date/time in iso format: 2015-06-02T10:15:02.325

If you want a different format you can use a formatter:

LocalDateTime datetime = LocalDateTime.ofInstant(i, ZoneOffset.UTC);
String formatted = DateTimeFormatter.ofPattern("yyyy-MM-dd hh:mm:ss").format(datetime);
System.out.println(formatted);

> use the -O option. [...] If the tar file is corrupt, the process will abort with an error.

Sometimes yes, but sometimes not. Let's see an example of a corrupted file:

echo Pete > my_name
tar -cf my_data.tar my_name 

# // Simulate a corruption
sed < my_data.tar 's/Pete/Fool/' > my_data_now.tar
# // "my_data_now.tar" is the corrupted file

tar -xvf my_data_now.tar -O

It shows:

my_name
Fool  

Even if you execute

echo $?

tar said that there was no error:

0

but the file was corrupted, it has now "Fool" instead of "Pete".

import operator
sorted_x = sorted(x, key=operator.attrgetter('score'))

if you want to sort x in-place, you can also:

x.sort(key=operator.attrgetter('score'))

You may find that using the `group' aes will help you get the result you want. For example:

tu <- expand.grid(Land       = gl(2, 1, labels = c("DE", "BB")),
                  Altersgr   = gl(5, 1, labels = letters[1:5]),
                  Geschlecht = gl(2, 1, labels = c('m', 'w')),
                  Jahr       = 2000:2009)

set.seed(42)
tu$Wert <- unclass(tu$Altersgr) * 200 + rnorm(200, 0, 10)

ggplot(tu, aes(x = Jahr, y = Wert, color = Altersgr, group = Altersgr)) + 
  geom_point() + geom_line() + 
  facet_grid(Geschlecht ~ Land)

Which produces the plot found here:

Do you have multiple mongodb nodes in a replica set?

I found (I am using via Robomongo gui mongo shell, I guess same applies in other cases) that the correct remove syntax, i.e.

db.test_users.remove({"_id": ObjectId("4d512b45cc9374271b02ec4f")})

...does not work unless you are connected to the primary node of the replica set.

It's worth noting CSS3 substring attribute selectors

[attribute^=value] { /* starts with selector */
/* Styles */
}

[attribute$=value] { /* ends with selector */
/* Styles */
}

[attribute*=value] { /* contains selector */
/* Styles */
}

You can use JavaScript functions like replace, and you can wrap the jQuery code in brackets:

var value = ($("#text").val()).replace(".", ":");

You could also just put the first SELECT in a subquery. Since most optimizers will fold it into a constant anyway, there should not be a performance hit on this.

Incidentally, since you are using a predicate like this:

CONVERT(...) = CONVERT(...)

that predicate expression cannot be optimized properly or use indexes on the columns reference by the CONVERT() function.

Here is one way to make the original query somewhat better:

DECLARE @ooDate datetime
SELECT @ooDate = OO.Date FROM OLAP.OutageHours AS OO where OO.OutageID = 1

SELECT 
  COUNT(FF.HALID)
FROM
  Outages.FaultsInOutages AS OFIO 
  INNER JOIN Faults.Faults as FF ON 
    FF.HALID = OFIO.HALID 
WHERE
  FF.FaultDate >= @ooDate AND
  FF.FaultDate < DATEADD(day, 1, @ooDate) AND
  OFIO.OutageID = 1

This version could leverage in index that involved FaultDate, and achieves the same goal.

Here it is, rewritten to use a subquery to avoid the variable declaration and subsequent SELECT.

SELECT 
  COUNT(FF.HALID)
FROM
  Outages.FaultsInOutages AS OFIO 
  INNER JOIN Faults.Faults as FF ON 
    FF.HALID = OFIO.HALID 
WHERE
  CONVERT(varchar(10), FF.FaultDate, 126) = (SELECT CONVERT(varchar(10), OO.Date, 126) FROM OLAP.OutageHours AS OO where OO.OutageID = 1) AND
  OFIO.OutageID = 1

Note that this approach has the same index usage issue as the original, because of the use of CONVERT() on FF.FaultDate. This could be remedied by adding the subquery twice, but you would be better served with the variable approach in this case. This last version is only for demonstration.

Regards.

Yeah.

command >> file to redirect just stdout of command.

command >> file 2>&1 to redirect stdout and stderr to the file (works in bash, zsh)

And if you need to use sudo, remember that just

sudo command >> /file/requiring/sudo/privileges does not work, as privilege elevation applies to command but not shell redirection part. However, simply using tee solves the problem:

command | sudo tee -a /file/requiring/sudo/privileges

I had almost the same example as you in this notebook where I wanted to illustrate the usage of an adjacent module's function in a DRY manner.

My solution was to tell Python of that additional module import path by adding a snippet like this one to the notebook:

import os
import sys
module_path = os.path.abspath(os.path.join('..'))
if module_path not in sys.path:
    sys.path.append(module_path)

This allows you to import the desired function from the module hierarchy:

from project1.lib.module import function
# use the function normally
function(...)

Note that it is necessary to add empty __init__.py files to project1/ and lib/ folders if you don't have them already.

If you want to uncheck all the checkboxes on a page, the easiest way is like this:

$('[type=checkbox]').prop("checked", false);

try using the permission of WRITE_EXTERNAL_STORAGE You should use that whether there is an external card or not.

This works well for me:

path = Environment.getExternalStoragePublicDirectory(
                Environment.DIRECTORY_MOVIES);
File file = new File(path, "/" + fname);

and places my files in the appropriate folder

In your quesion code you are using TimeSpan.FromMinutes incorrectly. Please see the MSDN Documentation for TimeSpan.FromMinutes, which gives the following method signature:

public static TimeSpan FromMinutes(double value)

hence, the following code won't compile

var intMinutes = TimeSpan.FromMinutes(varTime); // won't compile

Instead, you can use the TimeSpan.TotalMinutes property to perform this arithmetic. For instance:

TimeSpan varTime = (DateTime)varFinish - (DateTime)varValue; 
double fractionalMinutes = varTime.TotalMinutes;
int wholeMinutes = (int)fractionalMinutes;

Perl really only has three types: scalars, arrays, and hashes. And even that distinction is arguable. ;) The way each variable is treated depends on what you do with it:

% perl -e "print 5.4 . 3.4;"
5.43.4


% perl -e "print '5.4' + '3.4';"
8.8

At the top of your .vb file:

Imports System.data.sqlclient

Within your code:

'Setup SQL Command
Dim CMD as new sqlCommand("StoredProcedureName")
CMD.parameters("@Parameter1", sqlDBType.Int).value = Param_1_value

Dim connection As New SqlConnection(connectionString)
CMD.Connection = connection
CMD.CommandType = CommandType.StoredProcedure

Dim adapter As New SqlDataAdapter(CMD)
adapter.SelectCommand.CommandTimeout = 300

'Fill the dataset
Dim DS as DataSet    
adapter.Fill(ds)
connection.Close()   

'Now, read through your data:
For Each DR as DataRow in DS.Tables(0).rows
    Msgbox("The value in Column ""ColumnName1"": " & cstr(DR("ColumnName1")))
next

Now that the basics are out of the way,

I highly recommend abstracting the actual SqlCommand Execution out into a function.

Here is a generic function that I use, in some form, on various projects:

''' <summary>Executes a SqlCommand on the Main DB Connection. Usage: Dim ds As DataSet = ExecuteCMD(CMD)</summary>'''
''' <param name="CMD">The command type will be determined based upon whether or not the commandText has a space in it. If it has a space, it is a Text command ("select ... from .."),''' 
''' otherwise if there is just one token, it's a stored procedure command</param>''''
Function ExecuteCMD(ByRef CMD As SqlCommand) As DataSet
    Dim connectionString As String = ConfigurationManager.ConnectionStrings("main").ConnectionString
    Dim ds As New DataSet()

    Try
        Dim connection As New SqlConnection(connectionString)
        CMD.Connection = connection

        'Assume that it's a stored procedure command type if there is no space in the command text. Example: "sp_Select_Customer" vs. "select * from Customers"
        If CMD.CommandText.Contains(" ") Then
            CMD.CommandType = CommandType.Text
        Else
            CMD.CommandType = CommandType.StoredProcedure
        End If

        Dim adapter As New SqlDataAdapter(CMD)
        adapter.SelectCommand.CommandTimeout = 300

        'fill the dataset
        adapter.Fill(ds)
        connection.Close()

    Catch ex As Exception
        ' The connection failed. Display an error message.
        Throw New Exception("Database Error: " & ex.Message)
    End Try

    Return ds
End Function

Once you have that, your SQL Execution + reading code is very simple:

'----------------------------------------------------------------------'
Dim CMD As New SqlCommand("GetProductName")
CMD.Parameters.Add("@productID", SqlDbType.Int).Value = ProductID
Dim DR As DataRow = ExecuteCMD(CMD).Tables(0).Rows(0)
MsgBox("Product Name: " & cstr(DR(0)))
'----------------------------------------------------------------------'

_x000D_
<input type="radio" runat="server" name="testGroup" id="test3" /> <label for="<%=test3.ClientID %>" style="cursor:hand">Test3</label>

and in your method you can use like

return $('#test2').prop('checked');

Login to virtual machine use below command to check ip address. (anyone will work)

1. ifconfig
2. ip addr show

If you used NAT for your virtual machine settings(your machine ip will be 10.0.2.15), then you have to use port forwarding to connect to machine. IP address will be 127.0.0.1

If you used bridged networking/Host only networking, then you will have separate Ip address. Use that IP address to connect virtual machine

A handle is a sort of pointer in that it is typically a way of referencing some entity.

It would be more accurate to say that a pointer is one type of handle, but not all handles are pointers.

For example, a handle may also be some index into an in memory table, which corresponds to an entry that itself contains a pointer to some object.

The key thing is that when you have a "handle", you neither know nor care how that handle actually ends up identifying the thing that it identifies, all you need to know is that it does.

It should also be obvious that there is no single answer to "what exactly is a handle", because handles to different things, even in the same system, may be implemented in different ways "under the hood". But you shouldn't need to be concerned with those differences.

There's no need to group in that subquery... a where clause would suffice:

SELECT * FROM tblpm n
WHERE date_updated=(SELECT MAX(date_updated)
    FROM tblpm WHERE control_number=n.control_number)

Also, do you have an index on the 'date_updated' column? That would certainly help.

Try this with the + after [0-9]:

input type="text" pattern="[0-9]+" title="number only"

Actually, the first one is a bad idea. Use either the second one, or this:

struct greater
{
    template<class T>
    bool operator()(T const &a, T const &b) const { return a > b; }
};

std::sort(numbers.begin(), numbers.end(), greater());

That way your code won't silently break when someone decides numbers should hold long or long long instead of int.

If you want to change the table default character set and all character columns to a new character set, use a statement like this:

ALTER TABLE tbl_name CONVERT TO CHARACTER SET charset_name;

So query will be:

ALTER TABLE etape_prospection CONVERT TO CHARACTER SET utf8;

findOne, modify fields & save

    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);
});

You can also try like this:

public function storeAndLastInrestedId() {
    $data = new ModelName();
    $data->title = $request->title;
    $data->save();

    $last_insert_id = $data->id;
    return $last_insert_id;
}

When you check out a tag, you have what's called a "detached head". Normally, Git's HEAD commit is a pointer to the branch that you currently have checked out. However, if you check out something other than a local branch (a tag or a remote branch, for example) you have a "detached head" -- you're not really on any branch. You should not make any commits while on a detached head.

It's okay to check out a tag if you don't want to make any edits. If you're just examining the contents of files, or you want to build your project from a tag, it's okay to git checkout my_tag and work with the files, as long as you don't make any commits. If you want to start modifying files, you should create a branch based on the tag:

$ git checkout -b my_tag_branch my_tag

will create a new branch called my_tag_branch starting from my_tag. It's safe to commit changes on this branch.

It's pretty useful not to let the closing ?> in.

The file stays valid to PHP (not a syntax error) and as @David Dorward said it allows to avoid having white space / break-line (anything that can send a header to the browser) after the ?>.

For example,

<?
    header("Content-type: image/png");
    $img = imagecreatetruecolor ( 10, 10);
    imagepng ( $img);
?>
[space here]
[break line here]

won't be valid.

But

<?
    header("Content-type: image/png");
    $img = imagecreatetruecolor ( 10, 10 );
    imagepng ( $img );

will.

For once, you must be lazy to be secure.

This would be really bad to do because sharing your connection string opens up your website to so many vulnerabilities that you can't simply patch up, you have to use a different method if you want it to be secure. Otherwise you are opening up to a huge audience to take advantage of your site.

You can get any type of extra data from intent, no matter if it's an object or string or any type of data.

Bundle extra = getIntent().getExtras();

if (extra != null){
    String str1 = (String) extra.get("obj"); // get a object

    String str2 =  extra.getString("string"); //get a string
}

and the Shortest solution is:

Boolean isGranted = getIntent().getBooleanExtra("tag", false);

The way I usually explain this to people is to show how it's similar to other JavaScript patterns.

First, you should know that there are two ways to declare a function (actually, there's at least five, but these are the two main culprits):

function foo() {/*code*/}

and

var foo = function() {/*code*/};

Even if this construction looks strange, you probably use it all the time when attaching events:

window.onload=function(){/*code*/};

You should notice that the second form is not much different from a regular variable declaration:

var bar = 5;
var baz = 'some string';
var foo = function() {/*code*/};

But in JavaScript, you always have the choice between using a value directly or through a variable. If bar is 5, then the next two statements are equivalent:

var myVal = bar * 100; // use 'bar'
var myVal = 5 * 100;   // don't use 'bar'

Well, if you can use 5 on its own, why can't you use function() {\*code*\} on its own too? In fact, you can. And that's called an anonymous function. So these two examples are equivalent as well:

var foo = function() {/*code*/}; // use 'foo'
foo();                           

(function(){/*code*/})();        // don't use 'foo' 

The only difference you should see is in the extra brackets. That's simply because if you start a line with the keyword function, the parser will think you are declaring a function using the very first pattern at the top of this answer and throw a syntax error exception. So wrap your entire anonymous function inside a pair of braces and the problem goes away.

In other words, the following three statements are valid:

5;                        // pointless and stupid
'some string';            // pointless and stupid
(function(){/*code*/})(); // wonderfully powerful

[EDIT in 2020]

The previous version of my answer recommended Douglas Crockford's form of parens-wrapping for these "immediately invoked anonymous functions". User @RayLoveless recommended in 2012 to use the version shown now. Back then, before ES6 and arrow functions, there was no obvious idiomatic difference; you simply had to prevent the statement starting with the function keyword. In fact, there were lots of ways to do that. But using parens, these two statements were syntactically and idiomatically equivalent:

( function() { /* code */}() );
( function() { /* code */} )();

But user @zentechinc's comment below reminds me that arrow functions change all this. So now only one of these statements is correct.

( () => { /* code */ }() ); // Syntax error
( () => { /* code */ } )();

Why on earth does this matter? Actually, it's pretty easy to demonstrate. Remember an arrow function can come in two basic forms:

() => { return 5; };       // With a function body
() => { console.log(5); };

() => 5;                   // Or with a single expression
() => console.log(5);

Without parens wrapping this second type of arrow function, you end up with an idiomatic mess:

() => 5();              // How do you invoke a 5?
() => console.log(5)(); // console.log does not return a function!

I've seen some nice AngularJS charting solutions that make use of Highcharts. There's a highcharts-ng directive on GitHub to make AngularJS integration easier, and some examples on JSFiddle to give you a quick taste of what's possible.

You set up the chart on the JS side like this:

$scope.chart = {
    options: {
        chart: {
            type: 'bar'
        }
    },
    series: [{
        data: [10, 15, 12, 8, 7]
    }],
    title: {
        text: 'Hello'
    },
    loading: false
}

And then refer to it in the HTML like this:

<highchart id="chart1" config="chart"></highchart>

grep -r --include=*.{cc,h} "hello" .

This reads: search recursively (in all sub directories also) for all .cc OR .h files that contain "hello" at this . (current) directory

From another stackoverflow question

See inspect.getmembers(object[, predicate]).

Return all the members of an object in a list of (name, value) pairs sorted by name. If the optional predicate argument is supplied, only members for which the predicate returns a true value are included.

>>> [name for name,thing in inspect.getmembers([])]
['__add__', '__class__', '__contains__', '__delattr__', '__delitem__', 
'__delslice__',    '__doc__', '__eq__', '__format__', '__ge__', '__getattribute__',

Try this it will work...

<iframe src="Tmp.XLS" width="100%" height="500"></iframe>

But you can not save changes that you have done...It is used only for displaying purpose..

int[] nums = new int[100];

int sum = 0;

// Fill it with numbers using a for-loop for (int i = 0; i < nums.length; i++)

{ 
     nums[i] = i + 1;
    sum += n;
}

System.out.println(sum);

Had to do it... The action script way

//just make sure you pass a number to the function because it would accept you mother in law...
public var rad = function(x:*) {return x*Math.PI/180;}

protected  function distHaversine(p1:Object, p2:Object):Number {
    var R:int = 6371; // earth's mean radius in km
    var dLat:Number = rad(p2.lat() - p1.lat());
    var dLong:Number = rad(p2.lng() - p1.lng());

    var a:Number = Math.sin(dLat/2) * Math.sin(dLat/2) +
                Math.cos(rad(p1.lat())) * Math.cos(rad(p2.lat())) * Math.sin(dLong/2) * Math.sin(dLong/2);
    var c:Number = 2 * Math.atan2(Math.sqrt(a), Math.sqrt(1-a));
    var d:Number = R * c;

    return d;
}

try this:

function grab_image($url,$saveto){
    $ch = curl_init ($url);
    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_BINARYTRANSFER,1);
    $raw=curl_exec($ch);
    curl_close ($ch);
    if(file_exists($saveto)){
        unlink($saveto);
    }
    $fp = fopen($saveto,'x');
    fwrite($fp, $raw);
    fclose($fp);
}

and ensure that in php.ini allow_url_fopen is enable

I would mention one more thing that concerns Primefaces's p:commandButton!

When you use a p:commandButton for the action that needs to be done on the server, you can not use type="button" because that is for Push buttons which are used to execute custom javascript without causing an ajax/non-ajax request to the server.

For this purpose, you can dispense the type attribute (default value is "submit") or you can explicitly use type="submit".

Hope this will help someone!

A great real-world example of where lazy loading comes in handy is with ORM's (Object Relation Mappers) such as Entity Framework and NHibernate.

Say you have an entity Customer which has properties for Name, PhoneNumber, and Orders. Name and PhoneNumber are regular strings but Orders is a navigation property that returns a list of every order the customer ever made.

You often might want to go through all your customer's and get their name and phone number to call them. This is a very quick and simple task, but imagine if each time you created a customer it automatically went and did a complex join to return thousands of orders. The worst part is that you aren't even going to use the orders so it is a complete waste of resources!

This is the perfect place for lazy loading because if the Order property is lazy it will not go fetch all the customer's order unless you actually need them. You can enumerate the Customer objects getting only their Name and Phone Number while the Order property is patiently sleeping, ready for when you need it.

Alternatively to Martin's answer, you could also add the INTO part at the end of the query to make the query more readable:

SELECT Id, dateCreated FROM products INTO iId, dCreate

The key is the margin: 0 auto; on the inner div. A proof-of-concept example:

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN"
"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml" xml:lang="en" lang="en">
<body>
    <div style="background-color: blue; width: 100%;">
        <div style="background-color: yellow; width: 940px; margin: 0 auto;">
            Test
        </div>
    </div>
</body>
</html>

I'd very simply:

• Open the file for read/write
• Read/seek through it until the start of the line you want to delete
• Set the write pointer to the current read pointer
• Read through to the end of the line we're deleting and skip the newline delimiters (counting the number of characters as we go, we'll call it nline)
• Read byte-by-byte and write each byte to the file
• When finished truncate the file to (orig_length - nline).

The R in REST stands for resource

(Which isn't true, because it stands for Representational, but it's a good trick to remember the importance of Resources in REST).

About PUT /groups/api/v1/groups/{group id}/status/activate: you are not updating an "activate". An "activate" is not a thing, it's a verb. Verbs are never good resources. A rule of thumb: if the action, a verb, is in the URL, it probably is not RESTful.

What are you doing instead? Either you are "adding", "removing" or "updating" an activation on a Group, or if you prefer: manipulating a "status"-resource on a Group. Personally, I'd use "activations" because they are less ambiguous than the concept "status": creating a status is ambiguous, creating an activation is not.

• POST /groups/{group id}/activation Creates (or requests the creation of) an activation.
• PATCH /groups/{group id}/activation Updates some details of an existing activation. Since a group has only one activation, we know what activation-resource we are referring to.
• PUT /groups/{group id}/activation Inserts-or-replaces the old activation. Since a group has only one activation, we know what activation-resource we are referring to.
• DELETE /groups/{group id}/activation Will cancel, or remove the activation.

This pattern is useful when the "activation" of a Group has side-effects, such as payments being made, mails being sent and so on. Only POST and PATCH may have such side-effects. When e.g. a deletion of an activation needs to, say, notify users over mail, DELETE is not the right choice; in that case you probably want to create a deactivation resource: POST /groups/{group_id}/deactivation.

It is a good idea to follow these guidelines, because this standard contract makes it very clear for your clients, and all the proxies and layers between the client and you, know when it is safe to retry, and when not. Let's say the client is somewhere with flaky wifi, and its user clicks on "deactivate", which triggers a DELETE: If that fails, the client can simply retry, until it gets a 404, 200 or anything else it can handle. But if it triggers a POST to deactivation it knows not to retry: the POST implies this.
Any client now has a contract, which, when followed, will protect against sending out 42 emails "your group has been deactivated", simply because its HTTP-library kept retrying the call to the backend.

Updating a single attribute: use PATCH

PATCH /groups/{group id}

In case you wish to update an attribute. E.g. the "status" could be an attribute on Groups that can be set. An attribute such as "status" is often a good candidate to limit to a whitelist of values. Examples use some undefined JSON-scheme:

PATCH /groups/{group id} { "attributes": { "status": "active" } }
response: 200 OK

PATCH /groups/{group id} { "attributes": { "status": "deleted" } }
response: 406 Not Acceptable

Replacing the resource, without side-effects use PUT.

PUT /groups/{group id}

In case you wish to replace an entire Group. This does not necessarily mean that the server actually creates a new group and throws the old one out, e.g. the ids might remain the same. But for the clients, this is what PUT can mean: the client should assume he gets an entirely new item, based on the server's response.

The client should, in case of a PUT request, always send the entire resource, having all the data that is needed to create a new item: usually the same data as a POST-create would require.

PUT /groups/{group id} { "attributes": { "status": "active" } }
response: 406 Not Acceptable

PUT /groups/{group id} { "attributes": { "name": .... etc. "status": "active" } }
response: 201 Created or 200 OK, depending on whether we made a new one.

A very important requirement is that PUT is idempotent: if you require side-effects when updating a Group (or changing an activation), you should use PATCH. So, when the update results in e.g. sending out a mail, don't use PUT.

The "braces" are making an object literal, i.e. they create an object. It is one argument.

Example:

function someFunc(arg) {
    alert(arg.foo);
    alert(arg.bar);
}

someFunc({foo: "This", bar: "works!"});

the object can be created beforehand as well:

var someObject = {
    foo: "This", 
    bar: "works!"
};

someFunc(someObject);

I recommend to read the MDN JavaScript Guide - Working with Objects.

There's a strong culture of tuples being for heterogeneous collections, similar to what you'd use structs for in C, and lists being for homogeneous collections, similar to what you'd use arrays for. But I've never quite squared this with the mutability issue mentioned in the other answers. Mutability has teeth to it (you actually can't change a tuple), while homogeneity is not enforced, and so seems to be a much less interesting distinction.

input[value=""], input:not([value])

works with:

<input type="text" />
<input type="text" value="" />

But the style will not change as soon as someone will start typing (you need JS for that).

Here's all the options you have:

1. for...of (ES2015)

var dictionary = {_x000D_
    "data": [_x000D_
        {"id":"0","name":"ABC"},_x000D_
        {"id":"1","name":"DEF"}_x000D_
    ],_x000D_
    "images": [_x000D_
        {"id":"0","name":"PQR"},_x000D_
        {"id":"1","name":"xyz"}_x000D_
    ]_x000D_
};_x000D_
_x000D_
for (const entry of dictionary.data) {_x000D_
  console.log(JSON.stringify(entry))_x000D_
}

2. Array.prototype.forEach (ES5)

var dictionary = {_x000D_
    "data": [_x000D_
        {"id":"0","name":"ABC"},_x000D_
        {"id":"1","name":"DEF"}_x000D_
    ],_x000D_
    "images": [_x000D_
        {"id":"0","name":"PQR"},_x000D_
        {"id":"1","name":"xyz"}_x000D_
    ]_x000D_
};_x000D_
_x000D_
dictionary.data.forEach(function(entry) {_x000D_
  console.log(JSON.stringify(entry))_x000D_
})

3. for() (ES1)

var dictionary = {_x000D_
    "data": [_x000D_
        {"id":"0","name":"ABC"},_x000D_
        {"id":"1","name":"DEF"}_x000D_
    ],_x000D_
    "images": [_x000D_
        {"id":"0","name":"PQR"},_x000D_
        {"id":"1","name":"xyz"}_x000D_
    ]_x000D_
};_x000D_
_x000D_
for (let i = 0; i < dictionary.data.length; i++) {_x000D_
  console.log(JSON.stringify(dictionary.data[i]))_x000D_
}

We wrote a wrapper class that captures the buffer and converts the printed output to an exception. this lets us upgrade the phpmailer file without having to remember to comment out the echo statements each time we upgrade.

The wrapper class has methods something along the lines of:

public function AddAddress($email, $name = null) {
    ob_start();
    parent::AddAddress($email, $name);
    $error = ob_get_contents();
    ob_end_clean();
    if( !empty($error) ) {
        throw new Exception($error);
    }
}

Use -qscale:v to control quality

Use -qscale:v (or the alias -q:v) as an output option.

• Normal range for JPEG is 2-31 with 31 being the worst quality.
• The scale is linear with double the qscale being roughly half the bitrate.
• Recommend trying values of 2-5.
• You can use a value of 1 but you must add the -qmin 1 output option (because the default is -qmin 2).

To output a series of images:

ffmpeg -i input.mp4 -qscale:v 2 output_%03d.jpg

See the image muxer documentation for more options involving image outputs.

To output a single image at ~60 seconds duration:

ffmpeg -ss 60 -i input.mp4 -qscale:v 4 -frames:v 1 output.jpg

What you want is called a pivot, and it's not directly supported in MySQL, check this answer out for the options you've got:

How to pivot a MySQL entity-attribute-value schema

I wanted an utility class which is not managed by spring, so no spring annotations like @Component, @Configuration etc. But I wanted the class to read from application.properties

I managed to get it working by getting the class to be aware of the Spring Context, hence is aware of Environment, and hence environment.getProperty() works as expected.

To be explicit, I have:

application.properties

mypath=somestring

Utils.java

import org.springframework.core.env.Environment;

// No spring annotations here
public class Utils {
    public String execute(String cmd) {
        // Making the class Spring context aware
        ApplicationContextProvider appContext = new ApplicationContextProvider();
        Environment env = appContext.getApplicationContext().getEnvironment();

        // env.getProperty() works!!!
        System.out.println(env.getProperty("mypath")) 
    }
}

ApplicationContextProvider.java (see Spring get current ApplicationContext)

import org.springframework.beans.BeansException;
import org.springframework.context.ApplicationContext;
import org.springframework.context.ApplicationContextAware;
import org.springframework.stereotype.Component;

@Component
public class ApplicationContextProvider implements ApplicationContextAware {
    private static ApplicationContext CONTEXT;

    public ApplicationContext getApplicationContext() {
        return CONTEXT;
    }

    public void setApplicationContext(ApplicationContext context) throws BeansException {
        CONTEXT = context;
    }

    public static Object getBean(String beanName) {
        return CONTEXT.getBean(beanName);
    }
}

I had old MySQL and Centos OS (ver 6 I believe) that was not supported.
One day I couldn't access Plesk.
Using Filezilla, I copied files the database files from var/lib/mysql/databasename/ I then purchased a new server with new Centos 8 OS and MariaDB. In Plesk, I created a new database with the same name as my old one.
Using Filezilla, I then pasted the old database files into the newly created database folder. I could see the data in phpmyadmin but it was giving errors such as the ones described here. I happened to have an old sql backup dump file. I imported the dump file and it overwrote those files. I then pasted the old files back into var/lib/mysql/databasename/ I then had to do a repair in Plesk. To my suprise. It worked. I had over 6 months of order data restored and I didn't lose anything.

There's some proposition over the web (and this page) to use ViewConfiguration.getScaledTouchSlop() to have a device-scaled value for SWIPE_MIN_DISTANCE.

getScaledTouchSlop() is intended for the "scrolling threshold" distance, not swipe. The scrolling threshold distance has to be smaller than a "swing between page" threshold distance. For example, this function returns 12 pixels on my Samsung GS2, and the examples quoted in this page are around 100 pixels.

With API Level 8 (Android 2.2, Froyo), you've got getScaledPagingTouchSlop(), intended for page swipe. On my device, it returns 24 (pixels). So if you're on API Level < 8, I think "2 * getScaledTouchSlop()" should be the "standard" swipe threshold. But users of my application with small screens told me that it was too few... As on my application, you can scroll vertically, and change page horizontally. With the proposed value, they sometimes change page instead of scrolling.

You can only manually delete properties of objects. Thus:

var container = {};

container.instance = new class();

delete container.instance;

However, this won't work on any other pointers. Therefore:

var container = {};

container.instance = new class();

var pointer = container.instance;

delete pointer; // false ( ie attempt to delete failed )

Furthermore:

delete container.instance; // true ( ie attempt to delete succeeded, but... )

pointer; // class { destroy: function(){} }

So in practice, deletion is only useful for removing object properties themselves, and is not a reliable method for removing the code they point to from memory.

A manually specified destroy method could unbind any event listeners. Something like:

function class(){
  this.properties = { /**/ }

  function handler(){ /**/ }

  something.addEventListener( 'event', handler, false );

  this.destroy = function(){
    something.removeEventListener( 'event', handler );
  }
}

It looks like what you want to do is remove your first merge. You could follow the following procedure:

git checkout master      # Let's make sure we are on master branch
git reset --hard master~ # Let's get back to master before the merge
git pull                 # or git merge remote/master
git merge topic

That would give you what you want.

I feel that MWV (Model View Whatever) or MV* is a more flexible term to describe some of the uniqueness of Angularjs in my opinion. It helped me to understand that it is more than a MVC (Model View Controller) JavaScript framework, but it still uses MVC as it has a Model View, and Controller.

It also can be considered as a MVP (Model View Presenter) pattern. I think of a Presenter as the user-interface business logic in Angularjs for the View. For example by using filters that can format data for display. It's not business logic, but display logic and it reminds me of the MVP pattern I used in GWT.

In addition, it also can be a MVVM (Model View View Model) the View Model part being the two-way binding between the two. Last of all it is MVW as it has other patterns that you can use as well as mentioned by @Steve Chambers.

I agree with the other answers that getting pedantic on these terms can be detrimental, as the point is to understand the concepts from the terms, but by the same token, fully understanding the terms helps one when they are designing their application code, knowing what goes where and why.

var str1 = "add";
str1 = str1 + " ";

Linux service init script are stored into /etc/init.d. You can copy and customize /etc/init.d/skeleton file, and then call

service [yourservice] start|stop|restart

see http://www.ralfebert.de/blog/java/debian_daemon/. Its for Debian (so, Ubuntu as well) but fit more distribution.

Use the mysqlnd (native driver) for php.

If you're on Ubuntu:

sudo apt-get install php5-mysqlnd
sudo service apache2 restart

If you're on Centos:

sudo yum install php-mysqlnd
sudo service httpd restart

The native driver returns integer types appropriately.

Edit:

As @Jeroen has pointed out, this method will only work out-of-the-box for PDO.
As @LarsMoelleken has pointed out, this method will work with mysqli if you also set the MYSQLI_OPT_INT_AND_FLOAT_NATIVE option to true.

Example:

$mysqli = mysqli_init();
$mysqli->options(MYSQLI_OPT_INT_AND_FLOAT_NATIVE, TRUE);

On Lion the Users/[username]/Library is hidden.

To simply view in Finder, click the 'Go' menu at the top of the screen and hold down the 'alt' key to show 'Library'.

Click on 'Library' and you can see your previously hidden library folder.

Previously advised:

Use

chflags nohidden /users/[username]/library

in a terminal to display the folder.

Use:

function getvalues(){
var inps = document.getElementsByName('pname[]');
for (var i = 0; i <inps.length; i++) {
var inp=inps[i];
    alert("pname["+i+"].value="+inp.value);
}
}

Here is Demo.

A few comments:

• The Nyquist frequency is half the sampling rate.
• You are working with regularly sampled data, so you want a digital filter, not an analog filter. This means you should not use analog=True in the call to butter, and you should use scipy.signal.freqz (not freqs) to generate the frequency response.
• One goal of those short utility functions is to allow you to leave all your frequencies expressed in Hz. You shouldn't have to convert to rad/sec. As long as you express your frequencies with consistent units, the scaling in the utility functions takes care of the normalization for you.

Here's my modified version of your script, followed by the plot that it generates.

set encoding=utf-8  " The encoding displayed.
set fileencoding=utf-8  " The encoding written to file.

You may as well set both in your ~/.vimrc if you always want to work with utf-8.

this way i follow and its work for me fine, may it will works for you,

<iframe class="img-responsive" src="{{pdfLoc| trustThisUrl }}" ng-style="{
                height: iframeHeight * 0.75 + 'px'
            }" style="width:100%"></iframe>

here trustThisUrl is just filter,

angular.module("app").filter('trustThisUrl', ["$sce", function ($sce) {
        return function (val) {
            return $sce.trustAsResourceUrl(val);
        };
    }]);

I think I figured it out. Here's what I did (perhaps not the most elegant solution - suggestions on how to imp[rove this are very much welcome)

#names of columns in data frame
cols <- names(DF)
# character variables
cols.char <- c("fx_code","date")
#numeric variables
cols.num <- cols[!cols %in% cols.char]

DF.char <- DF[cols.char]
DF.num <- as.data.frame(lapply(DF[cols.num],as.numeric))
DF2 <- cbind(DF.char, DF.num)

I know that it is very late to answer the question, but it may help someone like me who spent lots off time to fetch data using hql

So the thing is you just have to write a query

Query query = session.createQuery("from Employee");

it will give you all the data list but to fetch data from this you have to write this line.

List<Employee> fetchedData = query.list();

As simple as it looks.

In your test, you are comparing the two TestParent beans, not the single TestedChild bean.

Also, Spring proxies your @Configuration class so that when you call one of the @Bean annotated methods, it caches the result and always returns the same object on future calls.

See here:

• How does Spring @Configuration cache references to beans

When you're using foreign key, your order of columns should be same for insertion.

For example, if you're adding (userid, password) in table1 from table2 then from table2 order should be same (userid, password) and not like (password,userid) where userid is foreign key in table2 of table1.

I use this...but have never done any metro app development, so I don't know of any restrictions on libraries available to you. (note, you'll need to mark your classes as with DataContract and DataMember attributes)

public static class JSONSerializer<TType> where TType : class
{
    /// <summary>
    /// Serializes an object to JSON
    /// </summary>
    public static string Serialize(TType instance)
    {
        var serializer = new DataContractJsonSerializer(typeof(TType));
        using (var stream = new MemoryStream())
        {
            serializer.WriteObject(stream, instance);
            return Encoding.Default.GetString(stream.ToArray());
        }
    }

    /// <summary>
    /// DeSerializes an object from JSON
    /// </summary>
    public static TType DeSerialize(string json)
    {
        using (var stream = new MemoryStream(Encoding.Default.GetBytes(json)))
        {
            var serializer = new DataContractJsonSerializer(typeof(TType));
            return serializer.ReadObject(stream) as TType;
        }
    }
}

So, if you had a class like this...

[DataContract]
public class MusicInfo
{
    [DataMember]
    public string Name { get; set; }

    [DataMember]
    public string Artist { get; set; }

    [DataMember]
    public string Genre { get; set; }

    [DataMember]
    public string Album { get; set; }

    [DataMember]
    public string AlbumImage { get; set; }

    [DataMember]
    public string Link { get; set; }

}

Then you would use it like this...

var musicInfo = new MusicInfo
{
     Name = "Prince Charming",
     Artist = "Metallica",
     Genre = "Rock and Metal",
     Album = "Reload",
     AlbumImage = "http://up203.siz.co.il/up2/u2zzzw4mjayz.png",
     Link = "http://f2h.co.il/7779182246886"
};

// This will produce a JSON String
var serialized = JSONSerializer<MusicInfo>.Serialize(musicInfo);

// This will produce a copy of the instance you created earlier
var deserialized = JSONSerializer<MusicInfo>.DeSerialize(serialized);

You can check for IsNull condition.

If IsNull({TABLE.FIELD}) or {TABLE.FIELD} = "" then
  // do something

Actually, it seems sufficient to merely attach a stock WebChromeClient to the client view, ala

mWebView.setWebChromeClient(new WebChromeClient());

and you need to have hardware acceleration turned on!

At least, if you don't need to play a full-screen video, there's no need to pull the VideoView out of the WebView and push it into the Activity's view. It will play in the video element's allotted rect.

Any ideas how to intercept the expand video button?

Newer JDK distributions ship with JConsole and VisualVM. Both are fantastic tools for getting the dirty details from a running Java process. If you have to do this programmatically, investigate JMX.

This error happens because you didn't install composer on your project.

run composer install command in your project path.

If you're not worried about a couple minutes time to do so, a solution would be to rm -rf node_modules and npm install again to rebuild the local modules.

I created a Extension method to Add/Update/Read Claims based on a given ClaimsIdentity

namespace Foobar.Common.Extensions
{
    public static class Extensions
    {
        public static void AddUpdateClaim(this IPrincipal currentPrincipal, string key, string value)
        {
            var identity = currentPrincipal.Identity as ClaimsIdentity;
            if (identity == null)
                return;

            // check for existing claim and remove it
            var existingClaim = identity.FindFirst(key);
            if (existingClaim != null)
                identity.RemoveClaim(existingClaim);

            // add new claim
            identity.AddClaim(new Claim(key, value));
            var authenticationManager = HttpContext.Current.GetOwinContext().Authentication;
            authenticationManager.AuthenticationResponseGrant = new AuthenticationResponseGrant(new ClaimsPrincipal(identity), new AuthenticationProperties() { IsPersistent = true });
        }

        public static string GetClaimValue(this IPrincipal currentPrincipal, string key)
        {
            var identity = currentPrincipal.Identity as ClaimsIdentity;
            if (identity == null)
                return null;

            var claim = identity.Claims.FirstOrDefault(c => c.Type == key);
            return claim.Value;
        }
    }
}

and then to use it

using Foobar.Common.Extensions;

namespace Foobar.Web.Main.Controllers
{
    public class HomeController : Controller
    {
        public ActionResult Index()
        {
            // add/updating claims
            User.AddUpdateClaim("key1", "value1");
            User.AddUpdateClaim("key2", "value2");
            User.AddUpdateClaim("key3", "value3");
        }

        public ActionResult Details()
        {
            // reading a claim
            var key2 = User.GetClaimValue("key2");          
        }
    }
}

You just need to name the anonymous property the same on both sides

on new { t1.ProjectID, SecondProperty = true } equals 
   new { t2.ProjectID, SecondProperty = t2.Completed } into j1

Based on the comments of @svick, here is another implementation that might make more sense:

from t1 in Projects
from t2 in Tasks.Where(x => t1.ProjectID == x.ProjectID && x.Completed == true)
                .DefaultIfEmpty()
select new { t1.ProjectName, t2.TaskName }

Add these two properties to your parent layout (ex: Linear Layout, Relative Layout)

android:focusable="false"
android:focusableInTouchMode="false" 

It will do the trick :)

After many attempts I was finally able to get this working. Essentially what I did was download and use the vmware converter to merge the two disks into one. After that I was able to attach the newly created disk to VitrualBox.

The steps involved are very simple:

BEFORE YOU DO ANYTHING!

1) MAKE A BACKUP!!! Even if you follow these instruction, you could screw things up, so make a backup. Just shutdown the VM and then make a copy of the directory where VM resides.

2) Uninstall VMware Tools from the VM that you are going to convert. If for some reason you forget this step, you can still uninstall it after getting everything running under VirtualBox by following these steps. Do yourself the favor and just do it now.

NOW THE FUN PART!!!

1) Download and install the VMware Converter. I used 5.0.1 build-875114, just use the latest.

2) Download and install VirtualBox

3) Fire up VMWare convertor:

4) Click on Convert machine

6) Browse to the .vmx for your VM and click Next.

7) Give the new VM a name and select the location where you want to put it. Click Next

8) Click Next on the Options screen. You shouldn't have to change anything here.

9) Click Finish on the Summary screen to begin the conversion.

10) The conversion should start. This will take a LOOONG time so be patient.

11) Hopefully all went well, if it did, you should see that the conversion is completed:

12) Now open up VirtualBox and click New.

13) Give your VM a name and select what Type and Version it is. Click Next.

14) Select the size of the memory you want to give it. Click Next.

15) For the Hard Drive, click Use and existing hard drive file and select the newly converted .vmdk file.

16) Now Click Settings and select the Storage menu. The issue is that by default VirtualBox will add the drive as an IDE. This won't work and we need as we need to put it on a SCSI controller.

17) Select the IDE controller and the Remove Controller button.

18) Now click the Add Controller button and select Add SCSI Controller

19) Click the Add Hard Disk button.

20) Click Choose existing disk

21) Select your .vmdk file. Click OK

22) Select the System menu.

23) Click Enable IO APIC. Then click OK

24) Congrats!!! Your VM is now confgiured! Click Start to startup the VM!

You mention adding the additional include directory (C/C++|General) and additional lib dependency (Linker|Input), but have you also added the additional library directory (Linker|General)?

Including a sample error message might also help people answer the question since it's not even clear if the error is during compilation or linking.

1) To answer your question:

  String s="Java";
  System.out.println(s.length()); 

It is located in server administration rather than in SQL development.

• From the home screen select the database server instance your database is located on from the server administration section on the far right.
• From the menu on the right select Data Export.
• Select the database you want to export and choose a location.
• Click start export.

What about using numpy.count_nonzero, something like

>>> import numpy as np
>>> y = np.array([1, 2, 2, 2, 2, 0, 2, 3, 3, 3, 0, 0, 2, 2, 0])

>>> np.count_nonzero(y == 1)
1
>>> np.count_nonzero(y == 2)
7
>>> np.count_nonzero(y == 3)

You can use Pillow (Website, Documentation, GitHub, PyPI). Pillow has the same interface as PIL, but works with Python 3.

Installation

$ pip install Pillow

If you don't have administrator rights (sudo on Debian), you can use

$ pip install --user Pillow

Other notes regarding the installation are here.

Code

from PIL import Image
with Image.open(filepath) as img:
    width, height = img.size

Speed

This needed 3.21 seconds for 30336 images (JPGs from 31x21 to 424x428, training data from National Data Science Bowl on Kaggle)

This is probably the most important reason to use Pillow instead of something self-written. And you should use Pillow instead of PIL (python-imaging), because it works with Python 3.

Alternative #1: Numpy (deprecated)

I keep scipy.ndimage.imread as the information is still out there, but keep in mind:

imread is deprecated! imread is deprecated in SciPy 1.0.0, and [was] removed in 1.2.0.

import scipy.ndimage
height, width, channels = scipy.ndimage.imread(filepath).shape

Alternative #2: Pygame

import pygame
img = pygame.image.load(filepath)
width = img.get_width()
height = img.get_height()

something like this?

DECLARE maxval, val, @ind INT;
SELECT MAX(ID) as maxval FROM table;

while (ind <= maxval  ) DO           

      select `value` as val from `table` where `ID`=ind;

      CALL fn(val);

      SET ind = ind+1;
end while;

$('.datepicker').datepicker({
    autoclose: true
}); 

Putting #pragma once at the top of your header file will ensure that it is only included once. Note that #pragma once is not standard C99, but supported by most modern compilers.

An alternative is to use include guards (e.g. #ifndef MY_FILE #define MY_FILE ... #endif /* MY_FILE */)

The default is height: auto in browser, but height: X% Defines the height in percentage of the containing block.

You could also do

SELECT row FROM table ORDER BY id DESC LIMIT 1;

This will sort rows by their ID in descending order and return the first row. This is the same as returning the row with the maximum ID. This of course assumes that id is unique among all rows. Otherwise there could be multiple rows with the maximum value for id and you'll only get one.

Quoting an article at programming.guide:

this has two uses in a Java program.

1. As a reference to the current object

The syntax in this case usually looks something like

this.someVariable = someVariable;

This type of use is described here: The 'this' reference (with examples)

2. To call a different constructor

The syntax in this case typically looks something like

MyClass() {
    this(DEFAULT_VALUE); // delegate to other constructor
}

MyClass(int value) {
    // ...
}

This type of use is described here: this(…) constructor call (with examples)

{"a":"\u00e1"} and {"a":"á"} are different ways to write the same JSON document; The JSON decoder will decode the unicode escape.

In php 5.4+, php's json_encode does have the JSON_UNESCAPED_UNICODE option for plain output. On older php versions, you can roll out your own JSON encoder that does not encode non-ASCII characters, or use Pear's JSON encoder and remove line 349 to 433.

I found a simple method to add arbitrary time to a Date object

Date d = new Date(new Date().getTime() + 86400000)

Where:

86 400 000ms = 1 Day  : 24*60*60*1000
 3 600 000ms = 1 Hour :    60*60*1000

See some of the answers to my similar question why-cant-i-push-from-a-shallow-clone and the link to the recent thread on the git list.

Ultimately, the 'depth' measurement isn't consistent between repos, because they measure from their individual HEADs, rather than (a) your Head, or (b) the commit(s) you cloned/fetched, or (c) something else you had in mind.

The hard bit is getting one's Use Case right (i.e. self-consistent), so that distributed, and therefore probably divergent repos will still work happily together.

It does look like the checkout --orphan is the right 'set-up' stage, but still lacks clean (i.e. a simple understandable one line command) guidance on the "clone" step. Rather it looks like you have to init a repo, set up a remote tracking branch (you do want the one branch only?), and then fetch that single branch, which feels long winded with more opportunity for mistakes.

Edit: For the 'clone' step see this answer

In order to avoid troubles compiling third party libraries that need boost installed in your system, run this:

I just assigned a new value to the timer:

mytimer.Change(10000, 0); // reset to 10 seconds

It works fine for me.

at the top of the code define the timer: System.Threading.Timer myTimer;

if (!active)
    myTimer = new Timer(new TimerCallback(TimerProc));

myTimer.Change(10000, 0);
active = true;

private void TimerProc(object state)
{
    // The state object is the Timer object.
    var t = (Timer)state;

    t.Dispose();
    Console.WriteLine("The timer callback executes.");
    active = false;
    
    // Action to do when timer is back to zero
}

To recap (and this is true of many languages not just Java):

"assert" is primarily used as a debugging aid by software developers during the debugging process. Assert-messages should never appear. Many languages provide a compile-time option that will cause all "asserts" to be ignored, for use in generating "production" code.

"exceptions" are a handy way to handle all kinds of error conditions, whether or not they represent logic errors, because, if you run into an error-condition such that you cannot continue, you can simply "throw them up into the air," from wherever you are, expecting someone else out there to be ready to "catch" them. Control is transferred in one step, straight from the code that threw the exception, straight to the catcher's mitt. (And the catcher can see the complete backtrace of calls that had taken place.)

Furthermore, callers of that subroutine don't have to check to see if the subroutine succeeded: "if we're here now, it must have succeeded, because otherwise it would have thrown an exception and we wouldn't be here now!" This simple strategy makes code-design and debugging much, much easier.

Exceptions conveniently allow fatal-error conditions to be what they are: "exceptions to the rule." And, for them to be handled by a code-path that is also "an exception to the rule ... "fly ball!"

I agree with aks, however instead of using

return a - b;

You should use

return a > b ? 1 : a < b ? -1 : 0;

Use the dec argument to set "," as the decimal point by adding:

 ce <- read.table("file.txt", header = TRUE, dec = ",")

v-model
it is two way data binding, it is used to bind html input element when you change input value then bounded data will be change.

v-model is used only for HTML input elements

ex: <input type="text" v-model="name" > 

v-bind
it is one way data binding,means you can only bind data to input element but can't change bounded data changing input element. v-bind is used to bind html attribute
ex:
<input type="text" v-bind:class="abc" v-bind:value="">

<a v-bind:href="home/abc" > click me </a>

there is a project. and there are important comments (and credits)

briefly: copy aidl file, add permissions to manifest, copy-paste source for telephony management )))

Some more info for you. AT commands you can send only if you are rooted. Than you can kill system process and send commands but you will need a reboot to allow your phone to receive and send calls =)))

I'm very hapy =) Now my Shake2MuteCall will get an update !

None of the answers I read worked in PuTTY, so I found a comment on this article:

In the settings for your connection, under "Window->Behavior" you'll find a setting "System Menu Appears on ALT alone". Then CTRL + L, ALT, l (that's a lower case L) will scroll the screen and then clear the scrollback buffer.

(relevant to the OP because I am connecting to an Ubuntu server, but also apparently relevant no matter what your server is running.)

axios signature for post is axios.post(url[, data[, config]]). So you want to send params object within the third argument:

.post(`/mails/users/sendVerificationMail`, null, { params: {
  mail,
  firstname
}})
.then(response => response.status)
.catch(err => console.warn(err));

This will POST an empty body with the two query params:

POST http://localhost:8000/api/mails/users/sendVerificationMail?mail=lol%40lol.com&firstname=myFirstName

Compute a list storing prime numbers first, e.g. 2 3 5 7 11 13 ...

Every time you prime factorize a number, use implementation by Triptych but iterating this list of prime numbers rather than natural integers.

You can add custom colors using bootstrap theming in your config file for example variables.scss and make sure you import that file before bootstrap when compiling.

$theme-colors: (
    "whatever": #900
);

Now you can do .btn-whatever

For Windows:

1. Please add this directory to your environment variable(Path):

C:\mingw-w64\x86_64-8.1.0-win32-seh-rt_v6-rev0\mingw64\bin\

2. For Include errors detected, mention the path of your include folder into

"includePath": [ "C:/mingw-w64/x86_64-8.1.0-win32-seh-rt_v6-rev0/mingw64/include/" ]

, as this is the path from where the compiler fetches the library to be included in your program.

Use its value directly:

In [79]: df[df.c > 0.5][['b', 'e']].values
Out[79]: 
array([[ 0.98836259,  0.82403141],
       [ 0.337358  ,  0.02054435],
       [ 0.29271728,  0.37813099],
       [ 0.70033513,  0.69919695]])

There are extra square brackets in the command you tried.

To install the latest version from the v1 branch, you can use:

Combining R.. and PickBoy answers for brevity

long strtol (const char *String, char **EndPointer, int Base)

// examples

strtol(s, &s, 10);

No. Every object can be casted to an java.lang.Object, not a String. If you want a string representation of whatever object, you have to invoke the toString() method; this is not the same as casting the object to a String.

I would suggest the following code, you can use this <script language="JavaScript" src="http://j.maxmind.com/app/geoip.js"></script> to get the latitude and longitude of a location, although it may not be so accurate however it worked for me;

code snippet below

After executing

mvn install:install-file -DgroupId=com.oracle -DartifactId=ojdbc6 -Dversion=11.2.0.3 -Dpackaging=jar -Dfile=ojdbc6.jar -DgeneratePom=true

You can set the fontsize directly in the call to set_xticklabels and set_yticklabels (as noted in previous answers). This will only affect one Axes at a time.

ax.set_xticklabels(x_ticks, rotation=0, fontsize=8)
ax.set_yticklabels(y_ticks, rotation=0, fontsize=8)

You can also set the ticklabel font size globally (i.e. for all figures/subplots in a script) using rcParams:

import matplotlib.pyplot as plt

plt.rc('xtick',labelsize=8)
plt.rc('ytick',labelsize=8)

Or, equivalently:

plt.rcParams['xtick.labelsize']=8
plt.rcParams['ytick.labelsize']=8

Finally, if this is a setting that you would like to be set for all your matplotlib plots, you could also set these two rcParams in your matplotlibrc file:

xtick.labelsize      : 8 # fontsize of the x tick labels
ytick.labelsize      : 8 # fontsize of the y tick labels

You can simply use DataColumnCollection.IndexOf

So that you can get the index of the required column by name then use it with your row:

row[dt.Columns.IndexOf("ColumnName")] = columnValue;

In angular 8:

//for catch:
import { catchError } from 'rxjs/operators';

//for throw:
import { Observable, throwError } from 'rxjs';

//and code should be written like this.

getEmployees(): Observable<IEmployee[]> {
    return this.http.get<IEmployee[]>(this.url).pipe(catchError(this.erroHandler));
  }

  erroHandler(error: HttpErrorResponse) {
    return throwError(error.message || 'server Error');
  }

For slice(start, stop), if stop is negative, stop will be set to:

string.length – Math.abs(stop)

rather than:

string.length – 1 – Math.abs(stop)

Well, you can't. Internal classes can't be visible outside of their assembly, so no explicit way to access it directly -AFAIK of course. The only way is to use runtime late-binding via reflection, then you can invoke methods and properties from the internal class indirectly.

If you are using an old version of FFMPEG and you cant upgrade you can do the following:

ffmpeg -i PATH/VIDEO_FILE_NAME.mp4 -i PATH/AUDIO_FILE_NAME.mp3 -vcodec copy -shortest DESTINATION_PATH/NEW_VIDEO_FILE_NAME.mp4

Notice that I used -vcodec

final RelativeLayout llLogin = (RelativeLayout) findViewById(R.id.rl_main);
        llLogin.setOnTouchListener(
                new View.OnTouchListener() {
                    @Override
                    public boolean onTouch(View view, MotionEvent ev) {
                        InputMethodManager imm = (InputMethodManager) this.getSystemService(
                                Context.INPUT_METHOD_SERVICE);
                        imm.hideSoftInputFromWindow(this.getCurrentFocus().getWindowToken(), 0);
                        return false;
                    }
                });

You need to perform the action from the thread that owns the control.

That's how I'm doing that without adding too much code noise:

control.Invoke(() => textBox1.Text += "hi");

Where Invoke overload is a simple extension from Lokad Shared Libraries:

/// <summary>
/// Invokes the specified <paramref name="action"/> on the thread that owns     
/// the <paramref name="control"/>.</summary>
/// <typeparam name="TControl">type of the control to work with</typeparam>
/// <param name="control">The control to execute action against.</param>
/// <param name="action">The action to on the thread of the control.</param>
public static void Invoke<TControl>(this TControl control, Action action) 
  where TControl : Control
{
  if (!control.InvokeRequired)
  {
    action();
  }
  else
  {
    control.Invoke(action);
  }
}

In my case, I was trying to build and get APK for an old Unity 3D project (so that I can play the game in my Android phone). I was using the most recent Android Studio version, and all the SDK packages I could download via SDK Manager in Android Studio. SDK Packages was located in

C:/Users/Onat/AppData/Local/Android/Sdk 

And the error message I got was the same except the JDK (Java Development Kit) version "jdk-12.0.2" . JDK was located in

C:\Program Files\Java\jdk-12.0.2

And Environment Variable in Windows was JAVA_HOME : C:\Program Files\Java\jdk-12.0.2

After 3 hours of research, I found out that Unity does not support JDK 10. As told in https://forum.unity.com/threads/gradle-build-failed-error-could-not-determine-java-version-from-10-0-1.532169/ . My suggestion is:

1. Uninstall unwanted JDK if you have one installed already. https://www.java.com/tr/download/help/uninstall_java.xml
2. Head to http://www.oracle.com/technetwork/java/javase/downloads/jdk8-downloads-2133151.html
3. Login to/Open a Oracle account if not already logged in.
4. Download the older but functional JDK 8 for your computer set-up(32 bit/64 bit, Windows/Linux etc.)
5. Install the JDK. Remember the installation path. (https://docs.oracle.com/cd/E19182-01/820-7851/inst_cli_jdk_javahome_t/)
6. If you are using Windows, Open Environment Variables and change Java Path via Right click My Computer/This PC>Properties>Advanced System Settings>Environment Variables>New>Variable Name: JAVA_HOME>Variable Value: [YOUR JDK Path, Mine was "C:\Program Files\Java\jdk1.8.0_221"]
7. In Unity 3D, press Edit > Preferences > External Tools and fill in the JDK path (Mine was "C:\Program Files\Java\jdk1.8.0_221").
8. Also, in the same pop-up, edit SDK Path. (Get it from Android Studio > SDK Manager > Android SDK > Android SDK Location.)
9. If needed, restart your computer for changes to take effect.

You can load an XML document into an XMLType, then query it, e.g.:

DECLARE
  x XMLType := XMLType(
    '<?xml version="1.0" ?> 
<person>
   <row>
       <name>Tom</name>
       <Address>
           <State>California</State>
           <City>Los angeles</City>
       </Address>
   </row>
   <row>
       <name>Jim</name>
       <Address>
           <State>California</State>
           <City>Los angeles</City>
       </Address>
   </row>
</person>');
BEGIN
  FOR r IN (
    SELECT ExtractValue(Value(p),'/row/name/text()') as name
          ,ExtractValue(Value(p),'/row/Address/State/text()') as state
          ,ExtractValue(Value(p),'/row/Address/City/text()') as city
    FROM   TABLE(XMLSequence(Extract(x,'/person/row'))) p
    ) LOOP
    -- do whatever you want with r.name, r.state, r.city
  END LOOP;
END;

You can add a custom task to do this. Here is a basic custom task for Python.

{
    "version": "0.1.0",
    "command": "c:\\Python34\\python",
    "args": ["app.py"],
    "problemMatcher": {
        "fileLocation": ["relative", "${workspaceRoot}"],
        "pattern": {
            "regexp": "^(.*)+s$",
            "message": 1
        }
    }
}

You add this to file tasks.json and press Ctrl + Shift + B to run it.

configure SSL in xampp/apache/conf/extra/httpd-vhost.conf

http

<VirtualHost *:80>
    DocumentRoot "C:/xampp/htdocs/myproject/web"
    ServerName www.myurl.com

    <Directory "C:/xampp/htdocs/myproject/web">
        Options All
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

https

<VirtualHost *:443>
    DocumentRoot "C:/xampp/htdocs/myproject/web"
    ServerName www.myurl.com
    SSLEngine on
    SSLCertificateFile "conf/ssl.crt/server.crt" 
    SSLCertificateKeyFile "conf/ssl.key/server.key"
    <Directory "C:/xampp/htdocs/myproject/web">
        Options All
        AllowOverride All
        Require all granted
    </Directory>
</VirtualHost>

make sure server.crt & server.key path given properly otherwise this will not work.

don't forget to enable vhost in httpd.conf

# Virtual hosts
Include etc/extra/httpd-vhosts.conf

Esc to make sure you exit insert mode, then :wq (colon w q) or ZZ (shift-Z shift-Z).

I am using this, both smaller and large images:

.product p.image {
text-align: center;
width: 220px;
height: 160px;
overflow: hidden;
}
.product p.image img{
max-width: 100%;
max-height: 100%;
}

If you use Apache, you can use mod_bandwith.

See here for configuration parameters.

instead of clearing the name text use placeholder attribute it is good practice

<input type="text" placeholder="name"  name="name">

I would use a composite (multi-column) key.

CREATE TABLE INFO (
    t1ID INT,
    t2ID INT,
    PRIMARY KEY (t1ID, t2ID)
) 

This way you can have t1ID and t2ID as foreign keys pointing to their respective tables as well.

If your static variables need to be set at runtime then a static {...} block is very helpful.

For example, if you need to set the static member to a value which is stored in a config file or database.

Also useful when you want to add values to a static Map member as you can't add these values in the initial member declaration.

In Angular 2+, try the @Input decorator

It allows for some nice property binding between parent and child components.

First create a global variable in the parent to hold the object/property that will be passed to the child.

Next create a global variable in the child to hold the object/property passed from the parent.

Then in the parent html, where the child template is used, add square brackets notation with the name of the child variable, then set it equal to the name of the parent variable. Example:

<child-component-template [childVariable] = parentVariable>
</child-component-template>

Finally, where the child property is defined in the child component, add the Input decorator:

@Input()
public childVariable: any

When your parent variable is updated, it should pass the updates to the child component, which will update its html.

Also, to trigger a function in the child component, take a look at ngOnChanges.

Everybody describes issue with getting annotations, but the problem is in definition of your annotation. You should to add to your annotation definition a @Retention(RetentionPolicy.RUNTIME):

@Retention(RetentionPolicy.RUNTIME)
@Target(ElementType.FIELD)
public @interface MyAnnotation{
    int id();
}

A good example comes from order processing. An order from a customer typically has an Order Number that identifies the order, some data that occurs once per order such as the order date and the Customer ID, and a series of line items. Each line item contains an item number that identifies a line item within an order, a product ordered, the quantity of that product, the price of the product, and the amount for the line item, which could be computed by multiplying the quantity by the price.

The number that identifies a line item only identifies it in the context of a single order. The first line item in every order is item number "1". The complete identity of a line item is the item number together with the order number of which it is a part.

The parent child relationship between orders and line items is therefore an identifying relationship. A closely related concept in ER modeling goes by the name "subentity", where line item is a subentity of order. Typically, a subentity has a mandatory child-parent identitying relationship to the entity that it's subordinate to.

In classical database design, the primary key of the LineItems table would be (OrderNumber, ItemNumber). Some of today's designers would give an item a separate ItemID, that serves as a primary key, and is autoincremented by the DBMS. I recommend classical design in this case.
