You could combine 2 formats:

3   dd/mm/yy   (British/French)
8   hh:mm:ss

according to CONVERT() function, and using + operator:

SELECT CONVERT(varchar(10),GETDATE(),3) + ' ' + CONVERT(varchar(10),GETDATE(),8)

Just to add here, whenever you get "error: device offline" means that connection with emulator & adb bridge has been broken due to time taken in emulator startup.

Rather than re-starting emulator at this point try below two commands which stops & start adb bridge again.

adb kill-server

adb start-server

the answer below is written by https://stackoverflow.com/users/3082682/cvizv on a page which does not exist anymore, since he has not enough rep to answer a question, I am posting it. No credits by me.

public String getImagePath(Uri uri){
   Cursor cursor = getContentResolver().query(uri, null, null, null, null);
   cursor.moveToFirst();
   String document_id = cursor.getString(0);
   document_id = document_id.substring(document_id.lastIndexOf(":")+1);
   cursor.close();

   cursor = getContentResolver().query( 
   android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI,
   null, MediaStore.Images.Media._ID + " = ? ", new String[]{document_id}, null);
   cursor.moveToFirst();
   String path = cursor.getString(cursor.getColumnIndex(MediaStore.Images.Media.DATA));
   cursor.close();

   return path;
}

Edit: There is a flow on the code; if device has more than one external storage (external sdcard, external usb etc.), above the code won't work non primary storages.

You should use promises for async operations where you don't know when it will be completed. A promise "represents an operation that hasn't completed yet, but is expected in the future." (https://developer.mozilla.org/en/docs/Web/JavaScript/Reference/Global_Objects/Promise)

An example implementation would be like:

myApp.factory('myService', function($http) {

    var getData = function() {

        // Angular $http() and then() both return promises themselves 
        return $http({method:"GET", url:"/my/url"}).then(function(result){

            // What we return here is the data that will be accessible 
            // to us after the promise resolves
            return result.data;
        });
    };


    return { getData: getData };
});


function myFunction($scope, myService) {
    var myDataPromise = myService.getData();
    myDataPromise.then(function(result) {  

       // this is only run after getData() resolves
       $scope.data = result;
       console.log("data.name"+$scope.data.name);
    });
}

Edit: Regarding Sujoys comment that What do I need to do so that myFuction() call won't return till .then() function finishes execution.

function myFunction($scope, myService) { 
    var myDataPromise = myService.getData(); 
    myDataPromise.then(function(result) { 
         $scope.data = result; 
         console.log("data.name"+$scope.data.name); 
    }); 
    console.log("This will get printed before data.name inside then. And I don't want that."); 
 }

Well, let's suppose the call to getData() took 10 seconds to complete. If the function didn't return anything in that time, it would effectively become normal synchronous code and would hang the browser until it completed.

With the promise returning instantly though, the browser is free to continue on with other code in the meantime. Once the promise resolves/fails, the then() call is triggered. So it makes much more sense this way, even if it might make the flow of your code a bit more complex (complexity is a common problem of async/parallel programming in general after all!)

Try:

<servlet-mapping>
    <servlet-name>spring</servlet-name>
    <url-pattern>/</url-pattern>
</servlet-mapping>

Worked for me!  

The answer above is kind of correct, you can't gracefully control how much native memory a java process allocates. It depends on what your application is doing.

That said, depending on platform, you may be able to do use some mechanism, ulimit for example, to limit the size of a java or any other process.

Just don't expect it to fail gracefully if it hits that limit. Native memory allocation failures are much harder to handle than allocation failures on the java heap. There's a fairly good chance the application will crash but depending on how critical it is to the system to keep the process size down that might still suit you.

For example, my module names are like jan_module/feb_module/mar_module.

month = 'feb'
exec 'from %s_module import *'%(month)

If you want to create a nested dictionary given a list (arbitrary length) for a path and perform a function on an item that may exist at the end of the path, this handy little recursive function is quite helpful:

def ensure_path(data, path, default=None, default_func=lambda x: x):
    """
    Function:

    - Ensures a path exists within a nested dictionary

    Requires:

    - `data`:
        - Type: dict
        - What: A dictionary to check if the path exists
    - `path`:
        - Type: list of strs
        - What: The path to check

    Optional:

    - `default`:
        - Type: any
        - What: The default item to add to a path that does not yet exist
        - Default: None

    - `default_func`:
        - Type: function
        - What: A single input function that takes in the current path item (or default) and adjusts it
        - Default: `lambda x: x` # Returns the value in the dict or the default value if none was present
    """
    if len(path)>1:
        if path[0] not in data:
            data[path[0]]={}
        data[path[0]]=ensure_path(data=data[path[0]], path=path[1:], default=default, default_func=default_func)
    else:
        if path[0] not in data:
            data[path[0]]=default
        data[path[0]]=default_func(data[path[0]])
    return data

Example:

data={'a':{'b':1}}
ensure_path(data=data, path=['a','c'], default=[1])
print(data) #=> {'a':{'b':1, 'c':[1]}}
ensure_path(data=data, path=['a','c'], default=[1], default_func=lambda x:x+[2])
print(data) #=> {'a': {'b': 1, 'c': [1, 2]}}

I simply solve this problem like this, which should work in all browsers:

ul li {
  color: red
}

ul li span {
  color: blue;
}

<ul>
  <li><span>Foo</span></li>
  <li><span>Bar</span></li>
  <li><span>Bat</span></li>
</ul>

Byte[] -> String: use system.convert.tobase64string

Convert.ToBase64String(byte[] data)

String -> Byte[]: use system.convert.frombase64string

Convert.FromBase64String(string data)

I've interpreted this question as:

"Can anyone tell me how to pass values for JavaScript for use in a JSP?"

If that's the case, this HTML file would pass a server-calculated variable to a JavaScript in a JSP.

<html>
    <body>
        <script type="text/javascript">
            var serverInfo = "<%=getServletContext().getServerInfo()%>";
            alert("Server information " + serverInfo);
        </script>
    </body>
</html>

find . -size +10000k -exec ls -sd {} +

If your version of find won't accept the + notation (which acts rather like xargs does), then you might use (GNU find and xargs, so find probably supports + anyway):

find . -size +10000k -print0 | xargs -0 ls -sd

or you might replace the + with \; (and live with the relative inefficiency of this), or you might live with problems caused by spaces in names and use the portable:

find . -size +10000k -print | xargs ls -sd

The -d on the ls commands ensures that if a directory is ever found (unlikely, but...), then the directory information will be printed, not the files in the directory. And, if you're looking for files more than 1 MB (as a now-deleted comment suggested), you need to adjust the +10000k to 1000k or maybe +1024k, or +2048 (for 512-byte blocks, the default unit for -size). This will list the size and then the file name. You could avoid the need for -d by adding -type f to the find command, of course.

I'm going to answer this myself.

I've determined that there is a difference. "git fetch --tags" might bring in all the tags, but it doesn't bring in any new commits!

Turns out one has to do this to be totally "up to date", i.e. replicated a "git pull" without the merge:

$ git fetch --tags
$ git fetch

This is a shame, because it's twice as slow. If only "git fetch" had an option to do what it normally does and bring in all the tags.

Just like any other environment variable, with SET:

SET PATH=%PATH%;c:\whatever\else

If you want to have a little safety check built in first, check to see if the new path exists first:

IF EXIST c:\whatever\else SET PATH=%PATH%;c:\whatever\else

If you want that to be local to that batch file, use setlocal:

setlocal
set PATH=...
set OTHERTHING=...

@REM Rest of your script

Read the docs carefully for setlocal/endlocal , and have a look at the other references on that site - Functions is pretty interesting too and the syntax is tricky.

The Syntax page should get you started with the basics.

This happened to me because I was using OpenVPN. I found a way that I don't need to stop using the VPN or manually add a network to the docker-compose file nor run any crazy script.

I switched to WireGuard instead of OpenVPN. More specifically, as I am running the nordvpn solution, I installed WireGuard and used their version of it, NordLynx.

>>> "{:.1f}".format(45.34531)
'45.3'

Or use the builtin round:

>>> round(45.34531, 1)
45.299999999999997

What you saw in Firefox was not the actual request; note that the HTTP method is OPTIONS, not POST. It was actually the 'pre-flight' request that the browser makes to determine whether a cross-domain AJAX request should be allowed:

http://www.w3.org/TR/cors/

The Access-Control-Request-Headers header in the pre-flight request includes the list of headers in the actual request. The server is then expected to report back whether these headers are supported in this context or not, before the browser submits the actual request.

Using Excel 2010 x64. XY plot: I could not see no tabs (it is late and I am probably tired blind, 250 limit?). Here is what worked for me:

Swap the data columns, to end with X_data in column A and Y_data in column B.

My original data had Y_data in column A and X_data in column B, and the graph was rotated 90deg clockwise. I was suffering. Then it hit me: an Excel XY plot literally wants {x,y} pairs, i.e. X_data in first column and Y_data in second column. But it does not tell you this right away. For me an XY plot means Y=f(X) plotted.

Another way around using cross join would be to specify column names inside cross join

select name, Subject, Marks 
from studentmarks
Cross Join (
values (Maths,'Maths'),(Science,'Science'),(English,'English')
) un(Marks, Subject)
where marks is not null;

As pointed out in the comments, you cannot catch an exception that's not thrown by the code within your try block. Try changing your code to:

try{
    Integer.parseInt(args[i-1]); // this only throws a NumberFormatException
}
catch(NumberFormatException e){
    throw new MojException("Bledne dane");
}

Always check the documentation to see what exceptions are thrown by each method. You may also wish to read up on the subject of checked vs unchecked exceptions before that causes you any confusion in the future.

You need to add the -i flag to the first command, to include the HTTP header in the output. This is required to print headers.

curl -X HEAD -i http://www.google.com

More here: https://serverfault.com/questions/140149/difference-between-curl-i-and-curl-x-head

It should also be noted that it might also be important to analyze the results of the micro benchmark when comparing different implementations. Therefore a significance test should be made.

This is because implementation A might be faster during most of the runs of the benchmark than implementation B. But A might also have a higher spread, so the measured performance benefit of A won't be of any significance when compared with B.

So it is also important to write and run a micro benchmark correctly, but also to analyze it correctly.

Your select statement is returning a sequence of anonymous type , not a sequence of DataRows. CopyToDataTable() is only available on IEnumerable<T> where T is or derives from DataRow. You can select r the row object to call CopyToDataTable on it.

var query = from r in matrix.AsEnumerable()
                where r.Field<string>("c_to") == c_to &&
                      r.Field<string>("p_to") == p_to
                 select r;

DataTable conversions = query.CopyToDataTable();

You can also implement CopyToDataTable Where the Generic Type T Is Not a DataRow.

Minder Saini's example above almost works, but the .navbar-brand needs to be reduced as well.

A working example (using it on my own site) with Bootstrap 3.3.4:

.navbar-nav > li > a, .navbar-brand {
    padding-top:5px !important; padding-bottom:0 !important;
    height: 30px;
}
.navbar {min-height:30px !important;}

Edit for Mobile... To make this example work on mobile as well, you have to change the styling of the navbar toggle like so

.navbar-toggle {
     padding: 0 0;
     margin-top: 7px;
     margin-bottom: 0;
}

Use:

• :ls - to list buffers
• :bd#n - to close buffer where #n is the buffer number (use ls to get it)

Examples:

• to delete buffer 2:

  :bd2
  

I tried the token verification method and got it to work ~3 times and wasted around 2 hours of time for that. For some reason it does not work very well for our company.

My solution was to change the authentication method from HTTPS to SSH. Here is a Github guide (https://help.github.com/en/github/authenticating-to-github/generating-a-new-ssh-key-and-adding-it-to-the-ssh-agent).

After you have created the SSH key, remember to change the SSH address origin:

git remote add origin [email protected]:user/repo.git

Thanks to @EdChum I was struggling with same problem especially when indexes do not match. Unfortunatly in pandas guide this case is missed (when you for example delete some rows)

import pandas as pd
t=pd.DataFrame()
t['a']=[1,2,3,4]
t=t.loc[t['a']>1] #now index starts from 1

u=pd.DataFrame()
u['b']=[1,2,3] #index starts from 0

#option 1
#keep index of t
u.index = t.index 

#option 2
#index of t starts from 0
t.reset_index(drop=True, inplace=True)

#now concat will keep number of rows 
r=pd.concat([t,u], axis=1)

Older versions of Python would only allow a single simple statement after for ...: if ...: or similar block introductory statements.

I see that one can have multiple simple statements on the same line as any of these. However, there are various combinations that don't work. For example we can:

for i in range(3): print "Here's i:"; print i

... but, on the other hand, we can't:

for i in range(3): if i % 2: print "That's odd!"

We can:

x=10
while x > 0: print x; x-=1

... but we can't:

x=10; while x > 0: print x; x-=1

... and so on.

In any event all of these are considered to be extremely NON-pythonic. If you write code like this then experience Pythonistas will probably take a dim view of your skills.

It's marginally acceptable to combine multiple statements on a line in some cases. For example:

x=0; y=1

... or even:

if some_condition(): break

... for simple break continue and even return statements or assigments.

In particular if one needs to use a series of elif one might use something like:

if     keystroke == 'q':   break
elif   keystroke == 'c':   action='continue'
elif   keystroke == 'd':   action='delete'
# ...
else:                      action='ask again'

... then you might not irk your colleagues too much. (However, chains of elif like that scream to be refactored into a dispatch table ... a dictionary that might look more like:

dispatch = {
    'q': foo.break,
    'c': foo.continue,
    'd': foo.delete
    }


# ...
while True:
    key = SomeGetKey()
    dispatch.get(key, foo.try_again)()

This may be coming in Late but I think I figured out a better way to load external configurations especially when you run your spring-boot app using java jar myapp.war instead of @PropertySource("classpath:some.properties")

The configuration would be loaded form the root of the project or from the location the war/jar file is being run from

public class Application implements EnvironmentAware {

    public static void main(String[] args) throws Exception {
        SpringApplication.run(Application.class, args);
    }

    @Override
    public void setEnvironment(Environment environment) {
        //Set up Relative path of Configuration directory/folder, should be at the root of the project or the same folder where the jar/war is placed or being run from
        String configFolder = "config";
        //All static property file names here
        List<String> propertyFiles = Arrays.asList("application.properties","server.properties");
        //This is also useful for appending the profile names
        Arrays.asList(environment.getActiveProfiles()).stream().forEach(environmentName -> propertyFiles.add(String.format("application-%s.properties", environmentName))); 
        for (String configFileName : propertyFiles) {
            File configFile = new File(configFolder, configFileName);
            LOGGER.info("\n\n\n\n");
            LOGGER.info(String.format("looking for configuration %s from %s", configFileName, configFolder));
            FileSystemResource springResource = new FileSystemResource(configFile);
            LOGGER.log(Level.INFO, "Config file : {0}", (configFile.exists() ? "FOund" : "Not Found"));
            if (configFile.exists()) {
                try {
                    LOGGER.info(String.format("Loading configuration file %s", configFileName));
                    PropertiesFactoryBean pfb = new PropertiesFactoryBean();
                    pfb.setFileEncoding("UTF-8");
                    pfb.setLocation(springResource);
                    pfb.afterPropertiesSet();
                    Properties properties = pfb.getObject();
                    PropertiesPropertySource externalConfig = new PropertiesPropertySource("externalConfig", properties);
                    ((ConfigurableEnvironment) environment).getPropertySources().addFirst(externalConfig);
                } catch (IOException ex) {
                    LOGGER.log(Level.SEVERE, null, ex);
                }
            } else {
                LOGGER.info(String.format("Cannot find Configuration file %s... \n\n\n\n", configFileName));

            }

        }
    }

}

Hope it helps.

This is a classic self-join, try the following:

SELECT e.ename, e.empno, m.ename as manager, e.mgr
FROM
    emp e, emp m
WHERE e.mgr = m.empno

And if you want to include the president which has no manager then instead of an inner join use an outer join in Oracle syntax:

SELECT e.ename, e.empno, m.ename as manager, e.mgr
FROM
    emp e, emp m
WHERE e.mgr = m.empno(+)

Or in ANSI SQL syntax:

SELECT e.ename, e.empno, m.ename as manager, e.mgr
FROM
    emp e
    LEFT OUTER JOIN emp m
        ON e.mgr = m.empno

Use android:gravity="center" in TextView instead of layout_gravity.

Round tripping dates through strings has always been a pain...but the docs to indicate that the 'o' specifier is the one to use for round tripping which captures the UTC state. When parsed the result will usually have Kind == Utc if the original was UTC. I've found that the best thing to do is always normalize dates to either UTC or local prior to serializing then instruct the parser on which normalization you've chosen.

DateTime now = DateTime.Now;
DateTime utcNow = now.ToUniversalTime();

string nowStr = now.ToString( "o" );
string utcNowStr = utcNow.ToString( "o" );

now = DateTime.Parse( nowStr );
utcNow = DateTime.Parse( nowStr, null, DateTimeStyles.AdjustToUniversal );

Debug.Assert( now == utcNow );

You're trying to create a tuple, but you're just parenthesizing a string :)

Add an extra ',':

dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=(dRecieved,))  # <- note extra ','
processThread.start()

Or use brackets to make a list:

dRecieved = connFile.readline()
processThread = threading.Thread(target=processLine, args=[dRecieved])  # <- 1 element list
processThread.start()

If you notice, from the stack trace: self.__target(*self.__args, **self.__kwargs)

The *self.__args turns your string into a list of characters, passing them to the processLine function. If you pass it a one element list, it will pass that element as the first argument - in your case, the string.

What about this:

var txt="";
var nyc = {
    fullName: "New York City",
    mayor: "Michael Bloomberg",
    population: 8000000,
    boroughs: 5
};

for (var x in nyc){
    txt += nyc[x];
}

First:

• Returns the first element of a sequence
• Throws exception: There are no elements in the result
• Use when: When more than 1 element is expected and you want only the first

FirstOrDefault:

• Returns the first element of a sequence, or a default value if no element is found
• Throws exception: Only if the source is null
• Use when: When more than 1 element is expected and you want only the first. Also it is ok for the result to be empty

del parentpath (or just place the .bat file inside parent folder) *.txt /s

That will delete all .txt files in the parent and all sub folders. If you want to delete multiple file extensions just add a space and do the same thing. Ex. *.txt *.dll *.xml

Finally, I found the solution:

final String path = "sample/folder";
final File jarFile = new File(getClass().getProtectionDomain().getCodeSource().getLocation().getPath());

if(jarFile.isFile()) {  // Run with JAR file
    final JarFile jar = new JarFile(jarFile);
    final Enumeration<JarEntry> entries = jar.entries(); //gives ALL entries in jar
    while(entries.hasMoreElements()) {
        final String name = entries.nextElement().getName();
        if (name.startsWith(path + "/")) { //filter according to the path
            System.out.println(name);
        }
    }
    jar.close();
} else { // Run with IDE
    final URL url = Launcher.class.getResource("/" + path);
    if (url != null) {
        try {
            final File apps = new File(url.toURI());
            for (File app : apps.listFiles()) {
                System.out.println(app);
            }
        } catch (URISyntaxException ex) {
            // never happens
        }
    }
}

The second block just work when you run the application on IDE (not with jar file), You can remove it if you don't like that.

You should be able to access the query using dot notation now.

If you want to access say you are receiving a GET request at /checkEmail?type=email&utm_source=xxxx&email=xxxxx&utm_campaign=XX and you want to fetch out the query used.

var type = req.query.type,
    email = req.query.email,
    utm = {
     source: req.query.utm_source,
     campaign: req.query.utm_campaign
    };

Params are used for the self defined parameter for receiving request, something like (example):

router.get('/:userID/food/edit/:foodID', function(req, res){
 //sample GET request at '/xavg234/food/edit/jb3552'

 var userToFind = req.params.userID;//gets xavg234
 var foodToSearch = req.params.foodID;//gets jb3552
 User.findOne({'userid':userToFind}) //dummy code
     .then(function(user){...})
     .catch(function(err){console.log(err)});
});

declare class & nested struct probably in some header file

class C {
    // struct will be private without `public:` keyword
    struct S {
        // members will be public without `private:` keyword
        int sa;
        void func();
    };
    void func(S s);
};

if you want to separate the implementation/definition, maybe in some CPP file

void C::func(S s) {
    // implementation here
}
void C::S::func() { // <= note that you need the `full path` to the function
    // implementation here
}

if you want to inline the implementation, other answers will do fine.

If you look at the code for the component you can see that it uses the className prop passed to it to combine with the row class to get the resulting set of classes (<Row className="aaa bbb"... works).Also, if you provide the id prop like <Row id="444" ... it will actually set the id attribute for the element.

From the spec, §15.9.1.1:

A Date object contains a Number indicating a particular instant in time to within a millisecond. Such a Number is called a time value. A time value may also be NaN, indicating that the Date object does not represent a specific instant of time.

Time is measured in ECMAScript in milliseconds since 01 January, 1970 UTC. In time values leap seconds are ignored. It is assumed that there are exactly 86,400,000 milliseconds per day. ECMAScript Number values can represent all integers from –9,007,199,254,740,992 to 9,007,199,254,740,992; this range suffices to measure times to millisecond precision for any instant that is within approximately 285,616 years, either forward or backward, from 01 January, 1970 UTC.

The actual range of times supported by ECMAScript Date objects is slightly smaller: exactly –100,000,000 days to 100,000,000 days measured relative to midnight at the beginning of 01 January, 1970 UTC. This gives a range of 8,640,000,000,000,000 milliseconds to either side of 01 January, 1970 UTC.

The exact moment of midnight at the beginning of 01 January, 1970 UTC is represented by the value +0.

The third paragraph being the most relevant. Based on that paragraph, we can get the precise earliest date per spec from new Date(-8640000000000000), which is Tuesday, April 20th, 271,821 BCE (BCE = Before Common Era, e.g., the year -271,821).

This is the solution how I figured out this issue:

@Override
public Dialog onCreateDialog(Bundle savedInstanceState) {
    Dialog dialog = super.onCreateDialog(savedInstanceState);    
    dialog.getWindow().requestFeature(Window.FEATURE_NO_TITLE);   

    return dialog;
}

@Override
public void onStart() {
    super.onStart();
    Dialog dialog = getDialog();
    if (dialog != null) {
            dialog.getWindow().setLayout(ViewGroup.LayoutParams.MATCH_PARENT, ViewGroup.LayoutParams.MATCH_PARENT);
            dialog.getWindow().setBackgroundDrawable(new ColorDrawable(Color.TRANSPARENT));
    }
}

1. Go here and download and install Notepad++
2. Go here and download and install Python 2.7 not 3.
3. Start, Run Powershell. Enter the following. [Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python27", "User")
4. Close Powershell and reopen it.
5. Make a directory for your programs. mkdir scripts
6. Open that directory cd scripts
7. In Notepad++, in a new file type: print "hello world"
8. Save the file as hello.py
9. Go back to powershell and make sure you are in the right directory by typing dir. You should see your file hello.py there.
10. At the Powershell prompt type: python hello.py

Canvas would be a great way to do this, as @pst said above. Check out this answer for a good example:

getPixel from HTML Canvas?

Some code that would serve you specifically as well:

var imgd = context.getImageData(x, y, width, height);
var pix = imgd.data;

for (var i = 0, n = pix.length; i < n; i += 4) {
  console.log pix[i+3]
}

This will go row by row, so you'd need to convert that into an x,y and either convert the for loop to a direct check or run a conditional inside.

Reading your question again, it looks like you want to be able to get the point that the person clicks on. This can be done pretty easily with jquery's click event. Just run the above code inside a click handler as such:

$('el').click(function(e){
   console.log(e.clientX, e.clientY)
}

Those should grab your x and y values.

A. Grab file data from the file field

The first thing to do is bind a function to the change event on your file field and a function for grabbing the file data:

// Variable to store your files
var files;

// Add events
$('input[type=file]').on('change', prepareUpload);

// Grab the files and set them to our variable
function prepareUpload(event)
{
  files = event.target.files;
}

This saves the file data to a file variable for later use.

B. Handle the file upload on submit

When the form is submitted you need to handle the file upload in its own AJAX request. Add the following binding and function:

$('form').on('submit', uploadFiles);

// Catch the form submit and upload the files
function uploadFiles(event)
{
  event.stopPropagation(); // Stop stuff happening
    event.preventDefault(); // Totally stop stuff happening

// START A LOADING SPINNER HERE

// Create a formdata object and add the files
var data = new FormData();
$.each(files, function(key, value)
{
    data.append(key, value);
});

$.ajax({
    url: 'submit.php?files',
    type: 'POST',
    data: data,
    cache: false,
    dataType: 'json',
    processData: false, // Don't process the files
    contentType: false, // Set content type to false as jQuery will tell the server its a query string request
    success: function(data, textStatus, jqXHR)
    {
        if(typeof data.error === 'undefined')
        {
            // Success so call function to process the form
            submitForm(event, data);
        }
        else
        {
            // Handle errors here
            console.log('ERRORS: ' + data.error);
        }
    },
    error: function(jqXHR, textStatus, errorThrown)
    {
        // Handle errors here
        console.log('ERRORS: ' + textStatus);
        // STOP LOADING SPINNER
    }
});
}

What this function does is create a new formData object and appends each file to it. It then passes that data as a request to the server. 2 attributes need to be set to false:

• processData - Because jQuery will convert the files arrays into strings and the server can't pick it up.
• contentType - Set this to false because jQuery defaults to application/x-www-form-urlencoded and doesn't send the files. Also setting it to multipart/form-data doesn't seem to work either.

C. Upload the files

Quick and dirty php script to upload the files and pass back some info:

<?php // You need to add server side validation and better error handling here

$data = array();

if(isset($_GET['files']))
{  
$error = false;
$files = array();

$uploaddir = './uploads/';
foreach($_FILES as $file)
{
    if(move_uploaded_file($file['tmp_name'], $uploaddir .basename($file['name'])))
    {
        $files[] = $uploaddir .$file['name'];
    }
    else
    {
        $error = true;
    }
}
$data = ($error) ? array('error' => 'There was an error uploading your files') : array('files' => $files);
}
else
{
    $data = array('success' => 'Form was submitted', 'formData' => $_POST);
}

echo json_encode($data);

?>

IMP: Don't use this, write your own.

D. Handle the form submit

The success method of the upload function passes the data sent back from the server to the submit function. You can then pass that to the server as part of your post:

function submitForm(event, data)
{
  // Create a jQuery object from the form
$form = $(event.target);

// Serialize the form data
var formData = $form.serialize();

// You should sterilise the file names
$.each(data.files, function(key, value)
{
    formData = formData + '&filenames[]=' + value;
});

$.ajax({
    url: 'submit.php',
    type: 'POST',
    data: formData,
    cache: false,
    dataType: 'json',
    success: function(data, textStatus, jqXHR)
    {
        if(typeof data.error === 'undefined')
        {
            // Success so call function to process the form
            console.log('SUCCESS: ' + data.success);
        }
        else
        {
            // Handle errors here
            console.log('ERRORS: ' + data.error);
        }
    },
    error: function(jqXHR, textStatus, errorThrown)
    {
        // Handle errors here
        console.log('ERRORS: ' + textStatus);
    },
    complete: function()
    {
        // STOP LOADING SPINNER
    }
});
}

Final note

This script is an example only, you'll need to handle both server and client side validation and some way to notify users that the file upload is happening. I made a project for it on Github if you want to see it working.

I am working in mysql workbench. When giving the values they have to be inside "". That solved it for me.

Do you want your function to react to an array argument or variable arguments? If the latter, try:

var func = function(...rest) {
  alert(rest.length);

  // In JS, don't use for..in with arrays
  // use for..of that consumes array's pre-defined iterator
  // or a more functional approach
  rest.forEach((v) => console.log(v));
};

But if you wish to handle an array argument

var fn = function(arr) {
  alert(arr.length);

  for(var i of arr) {
    console.log(i);
  }
};

In the AndroidManifest.xml, under the application tag, you can set the theme of your choice. To customize the theme, press Ctrl + Click on android:theme = "@style/AppTheme" in the Android manifest file. It will open styles.xml file where you can change the parent attribute of the style tag.

At parent= in styles.xml you can browse all available styles by using auto-complete inside the "". E.g. try parent="Theme." with your cursor right after the . and then pressing Ctrl + Space.

You can also preview themes in the preview window in Android Studio.

i personally would prefer

if(true == foo)
{
}

there is no chance for the ==/= mistype and i find it more expressive in terms of foo's type. But it is a very subjective question.

  componentDidMount() {
    const s = document.createElement('script');

    s.async = true;
    s.innerHTML = "document.write('This is output by document.write()!')";
    this.instance.appendChild(s);

The div is bound to this and the script is injected into it.

you need to user your mysql path like this:

Your understanding is slightly flawed. The diamond operator is a nice feature as you don't have to repeat yourself. It makes sense to define the type once when you declare the type but just doesn't make sense to define it again on the right side. The DRY principle.

Now to explain all the fuzz about defining types. You are right that the type is removed at runtime but once you want to retrieve something out of a List with type definition you get it back as the type you've defined when declaring the list otherwise it would lose all specific features and have only the Object features except when you'd cast the retrieved object to it's original type which can sometimes be very tricky and result in a ClassCastException.

Using List<String> list = new LinkedList() will get you rawtype warnings.

Public Function TestError() As String()
     Return {"foo", "bar"}
End Function

Works fine for me and should work for you, but you may need allow using implicit declarations in your project. I believe this is turning off Options strict in the Compile section of the program settings.

Since you are using VS 2008 (VB.NET 9.0) you have to declare create the new instance

New String() {"foo", "Bar"}

One way would be with sed. For example:

echo $name | sed -e 's?http://www\.??'

Normally the sed regular expressions are delimited by `/', but you can use '?' since you're searching for '/'. Here's another bash trick. @DigitalTrauma's answer reminded me that I ought to suggest it. It's similar:

echo ${name#http://www.}

(DigitalTrauma also gets credit for reminding me that the "http://" needs to be handled.)

you can use like this

private dynamic defaultReminder => reminder.TimeSpanText[TimeSpan.FromMinutes(15)]; 

instead of remove() you can use exclude() function to remove an object from the queryset. it's syntax is similar to filter()

eg : -

qs = qs.exclude(id= 1)

in above code it removes all objects from qs with id '1'

additional info :-

filter() used to select specific objects but exclude() used to remove

This can also happen if you've recently upgraded Ant. I was using Ant 1.8.4 on a project, and upgraded Ant to 1.9.4, and started to get this error when building a fat jar using Ant.

The solution for me was to downgrade back to Ant 1.8.4 for the command line and Eclipse using the process detailed here

If you want the number of rows to be flexible, you can add row_number in the SQL. For SQL server:

SELECT ROW_NUMBER() OVER (ORDER BY myOrder) ROW_NUMBER, * FROM myTable

Then filter the datatable on row_number:

Dataview dv= new Dataview(dt, "ROW_NUMBER<=100", "", CurrentRows)

If you know the arrays are of the same size it is provably faster to sort then compare

Arrays.sort(array1)
Arrays.sort(array2)
return Arrays.equals(array1, array2)

If you do not want to change the order of the data in the arrays then do a System.arraycopy first.

It's a one-liner with mutate_at:

dat %>% mutate_at("l1", factor) %>% mutate_at("l2", as.numeric)

You can also use JFormattedTextField, which is much simpler to use. Example:

public static void main(String[] args) {
    NumberFormat format = NumberFormat.getInstance();
    NumberFormatter formatter = new NumberFormatter(format);
    formatter.setValueClass(Integer.class);
    formatter.setMinimum(0);
    formatter.setMaximum(Integer.MAX_VALUE);
    formatter.setAllowsInvalid(false);
    // If you want the value to be committed on each keystroke instead of focus lost
    formatter.setCommitsOnValidEdit(true);
    JFormattedTextField field = new JFormattedTextField(formatter);

    JOptionPane.showMessageDialog(null, field);

    // getValue() always returns something valid
    System.out.println(field.getValue());
}

Try the InetAddressValidator utility class.

Here is another way to reproduce this error in Python2.7 with numpy:

import numpy as np
a = np.array([1,2,3])
b = np.array([4,5,6])
c = np.concatenate(a,b)   #note the lack of tuple format for a and b
print(c) 

The np.concatenate method produces an error:

TypeError: only length-1 arrays can be converted to Python scalars

If you read the documentation around numpy.concatenate, then you see it expects a tuple of numpy array objects. So surrounding the variables with parens fixed it:

import numpy as np
a = np.array([1,2,3])
b = np.array([4,5,6])
c = np.concatenate((a,b))  #surround a and b with parens, packaging them as a tuple
print(c) 

Then it prints:

[1 2 3 4 5 6]

What's going on here?

That error is a case of bubble-up implementation - it is caused by duck-typing philosophy of python. This is a cryptic low-level error python guts puke up when it receives some unexpected variable types, tries to run off and do something, gets part way through, the pukes, attempts remedial action, fails, then tells you that "you can't reformulate the subspace responders when the wind blows from the east on Tuesday".

In more sensible languages like C++ or Java, it would have told you: "you can't use a TypeA where TypeB was expected". But Python does it's best to soldier on, does something undefined, fails, and then hands you back an unhelpful error. The fact we have to be discussing this is one of the reasons I don't like Python, or its duck-typing philosophy.

using padding pad

In order to move the colorbar relative to the subplot, one may use the pad argument to fig.colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, orientation="horizontal", pad=0.2)
plt.show()

using an axes divider

One can use an instance of make_axes_locatable to divide the axes and create a new axes which is perfectly aligned to the image plot. Again, the pad argument would allow to set the space between the two axes.

import matplotlib.pyplot as plt
from mpl_toolkits.axes_grid1 import make_axes_locatable
import numpy as np; np.random.seed(1)

fig, ax = plt.subplots(figsize=(4,4))
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

divider = make_axes_locatable(ax)
cax = divider.new_vertical(size="5%", pad=0.7, pack_start=True)
fig.add_axes(cax)
fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

using subplots

One can directly create two rows of subplots, one for the image and one for the colorbar. Then, setting the height_ratios as gridspec_kw={"height_ratios":[1, 0.05]} in the figure creation, makes one of the subplots much smaller in height than the other and this small subplot can host the colorbar.

import matplotlib.pyplot as plt
import numpy as np; np.random.seed(1)

fig, (ax, cax) = plt.subplots(nrows=2,figsize=(4,4), 
                  gridspec_kw={"height_ratios":[1, 0.05]})
im = ax.imshow(np.random.rand(11,16))
ax.set_xlabel("x label")

fig.colorbar(im, cax=cax, orientation="horizontal")

plt.show()

Here a very simple but effective code using cElementTree.

def find_in_tree(tree, node):
    found = tree.find(node)
    if found == None:
        print "No %s in file" % node
        found = []
    return found  

# Parse a xml file (specify the path)
def_file = "xml_file_name.xml"
try:
    dom = ET.parse(open(def_file, "r"))
    root = dom.getroot()
except:
    exit_err("Unable to open and parse input definition file: " + def_file)

fwdefs = find_in_tree(root,"myNode")

This is from "python xml parse".

You may use the C atoi function ( in a try / catch clause because the conversion isn't always possible) But there's nothing in the MFC classes to do it better.

Use the --force (-f) flag on your mysql import. Rather than stopping on the offending statement, MySQL will continue and just log the errors to the console.

For example:

mysql -u userName -p -f -D dbName < script.sql

The print statement in Python converts its arguments to strings, and outputs those strings to stdout. To save the string to a variable instead, only convert it to a string:

a = str(tag.getArtist())

Also remember that it must be:

#include "stdafx.h"
#include <iostream>

and not the other way around

#include <iostream>
#include "stdafx.h"

On a related note: the java compiler uses int to represent boolean since JVM has a limited support for the boolean type.See Section 3.3.4 The boolean type.

In JVM, the integer zero represents false, and any non-zero integer represents true (Source : Inside Java Virtual Machine by Bill Venners)

The list may contain several elements, so the get method takes an argument : the index of the element you want to retrieve. If you want the first one, then it's 0.

The list contains Car instances, so you just have to do

Car firstCar = car.get(0);
String price = firstCar.getPrice();

or just

String price = car.get(0).getPrice();

The car variable should be named cars, since it's a list and thus contains several cars.

Read the tutorial about collections. And learn to use the javadoc: all the classes and methods are documented.

You could get the full path as a string then split it into a list using your operating system's separator character. Then you get the program name, folder name etc by accessing the elements from the end of the list using negative indices.

Like this:

import os
strPath = os.path.realpath(__file__)
print( f"Full Path    :{strPath}" )
nmFolders = strPath.split( os.path.sep )
print( "List of Folders:", nmFolders )
print( f"Program Name :{nmFolders[-1]}" )
print( f"Folder Name  :{nmFolders[-2]}" )
print( f"Folder Parent:{nmFolders[-3]}" )

The output of the above was this:

Full Path    :C:\Users\terry\Documents\apps\environments\dev\app_02\app_02.py
List of Folders: ['C:', 'Users', 'terry', 'Documents', 'apps', 'environments', 'dev', 'app_02', 'app_02.py']
Program Name :app_02.py
Folder Name  :app_02
Folder Parent:dev

JavaScript has an eval function that evaluates a string and executes it as code:

eval(settings.functionName + '(' + t.parentNode.id + ')');

The clone is a shallow copy of the array.

This test code prints:

[1, 2] / [1, 2]
[100, 200] / [100, 2]

because the MutableInteger is shared in both arrays as objects[0] and objects2[0], but you can change the reference objects[1] independently from objects2[1].

All the answers are not really correct, try this:

select * from shirts where 1 IN (colors);

Too many!

The "ANSI C" way buffer is redundant, since a FILE is already buffered. (The size of this internal buffer is what BUFSIZ actually defines.)

The "OWN-BUFFER-C++-WAY" will be slow as it goes through fstream, which does a lot of virtual dispatching, and again maintains internal buffers or each stream object. (The "COPY-ALGORITHM-C++-WAY" does not suffer this, as the streambuf_iterator class bypasses the stream layer.)

I prefer the "COPY-ALGORITHM-C++-WAY", but without constructing an fstream, just create bare std::filebuf instances when no actual formatting is needed.

For raw performance, you can't beat POSIX file descriptors. It's ugly but portable and fast on any platform.

The Linux way appears to be incredibly fast — perhaps the OS let the function return before I/O was finished? In any case, that's not portable enough for many applications.

EDIT: Ah, "native Linux" may be improving performance by interleaving reads and writes with asynchronous I/O. Letting commands pile up can help the disk driver decide when is best to seek. You might try Boost Asio or pthreads for comparison. As for "can't beat POSIX file descriptors"… well that's true if you're doing anything with the data, not just blindly copying.

All do not work for me on eloquent collections, laravel eloquent collections use the key from the items I think which causes merging issues, you need to get the first collection back as an array, put that into a fresh collection and then push the others into the new collection;

public function getFixturesAttribute()
{
    $fixtures = collect( $this->homeFixtures->all() );
    $this->awayFixtures->each( function( $fixture ) use ( $fixtures ) {
        $fixtures->push( $fixture );
    });
    return $fixtures;
}

var img = document.createElement('img');
img.src = 'my_image.jpg';
document.getElementById('container').appendChild(img);

I'll throw my hat into the ring just to talk about securing passwords in general on Android. On Android, the device binary should be considered compromised - this is the same for any end application which is in direct user control. Conceptually, a hacker could use the necessary access to the binary to decompile it and root out your encrypted passwords and etc.

As such there's two suggestions I'd like to throw out there if security is a major concern for you:

1) Don't store the actual password. Store a granted access token and use the access token and the signature of the phone to authenticate the session server-side. The benefit to this is that you can make the token have a limited duration, you're not compromising the original password and you have a good signature that you can use to correlate to traffic later (to for instance check for intrusion attempts and invalidate the token rendering it useless).

2) Utilize 2 factor authentication. This may be more annoying and intrusive but for some compliance situations unavoidable.

As the accepted answer has two important shortfalls, I'm posting the improved answer for those new comers who are looking for a correct answer:

foreach (array_filter(glob('/Path/To/*'), 'is_file') as $file)
{
    // Do something with $file
}

1. Filtering the globe function results with is_file is necessary, because it might return some directories as well.
2. Not all files have a . in their names, so */* pattern sucks in general.

onBlur is when your focus is no longer on the field in question.

The onblur property returns the onBlur event handler code, if any, that exists on the current element.

onChange is when the value of the field changes.

Maybe the solution someone is looking for is this:

Response.Redirect("/Sucesso")

This work when used in the View as well.

If the to-be-updated component is not inside the same NamingContainer component (ui:repeat, h:form, h:dataTable, etc), then you need to specify the "absolute" client ID. Prefix with : (the default NamingContainer separator character) to start from root.

<p:ajax process="@this" update="count :subTotal"/>

To be sure, check the client ID of the subTotal component in the generated HTML for the actual value. If it's inside for example a h:form as well, then it's prefixed with its client ID as well and you would need to fix it accordingly.

<p:ajax process="@this" update="count :formId:subTotal"/>

Space separation of IDs is more recommended as <f:ajax> doesn't support comma separation and starters would otherwise get confused.

Kotlin Users,

viewPager.addOnPageChangeListener(object : ViewPager.OnPageChangeListener {

            override fun onPageScrollStateChanged(state: Int) {
            }

            override fun onPageScrolled(position: Int, positionOffset: Float, positionOffsetPixels: Int) {

            }

            override fun onPageSelected(position: Int) {
            }
        })

Update 2020 for ViewPager2

        viewPager.registerOnPageChangeCallback(object : ViewPager2.OnPageChangeCallback() {
        override fun onPageScrollStateChanged(state: Int) {
            println(state)
        }

        override fun onPageScrolled(
            position: Int,
            positionOffset: Float,
            positionOffsetPixels: Int
        ) {
            super.onPageScrolled(position, positionOffset, positionOffsetPixels)
            println(position)
        }


        override fun onPageSelected(position: Int) {
            super.onPageSelected(position)
            println(position)
        }
    })

Just to add to the info here, The Fluid Project has a nice wiki write-up overviewing a large number of date and/or time pickers here.

As Jage's answer removes the element completely, including event handlers and data, I'm adding a simple solution that doesn't do that, thanks to the detach function.

var element = $('#childNode').detach();
$('#parentNode').append(element);

Edit:

Igor Mukhin suggested an even shorter version in the comments below:

$("#childNode").detach().appendTo("#parentNode");

With a wider view of what you're actually trying to do and the context in which you're doing it, I'm sure we could give you a better answer than the literal answer to your question.

But here's a literal answer:

If you're assigning these functions to some property somewhere, you can wrap the original function and put your replacement on the property instead:

// Original code in main.js
var theProperty = init;

function init(){
     doSomething();
}

// Extending it by replacing and wrapping, in extended.js
theProperty = (function(old) {
    function extendsInit() {
        old();
        doSomething();
    }

    return extendsInit;
})(theProperty);

If your functions aren't already on an object, you'd probably want to put them there to facilitate the above. For instance:

// In main.js
var MyLibrary = {
    init: function init() {
    }
};

// In extended.js
(function() {
    var oldInit = MyLibrary.init;
    MyLibrary.init = extendedInit;
    function extendedInit() {
        oldInit.call(MyLibrary); // Use #call in case `init` uses `this`
        doSomething();
    }
})();

But there are better ways to do that. Like for instance, providing a means of registering init functions.

// In main.js
var MyLibrary = (function() {
    var initFunctions = [];
    return {
        init: function init() {
            var fns = initFunctions;
            initFunctions = undefined;
            for (var index = 0; index < fns.length; ++index) {
                try { fns[index](); } catch (e) { }
            }
        },
        addInitFunction: function addInitFunction(fn) {
            if (initFunctions) {
                // Init hasn't run yet, remember it
                initFunctions.push(fn);
            } else {
                // `init` has already run, call it almost immediately
                // but *asynchronously* (so the caller never sees the
                // call synchronously)
                setTimeout(fn, 0);
            }
        }
    };
})();

Here in 2020 (or really any time after ~2016), that can be written a bit more compactly:

// In main.js
const MyLibrary = (() => {
    let initFunctions = [];
    return {
        init() {
            const fns = initFunctions;
            initFunctions = undefined;
            for (const fn of fns) {
                try { fn(); } catch (e) { }
            }
        },
        addInitFunction(fn) {
            if (initFunctions) {
                // Init hasn't run yet, remember it
                initFunctions.push(fn);
            } else {
                // `init` has already run, call it almost immediately
                // but *asynchronously* (so the caller never sees the
                // call synchronously)
                setTimeout(fn, 0);
                // Or: `Promise.resolve().then(() => fn());`
                // (Not `.then(fn)` just to avoid passing it an argument)
            }
        }
    };
})();

Addendum: No one mentioned "Populate" --- it is very much worth your time and money looking at Mongooses Populate Method : Also explains cross documents referencing

http://mongoosejs.com/docs/populate.html

You need to install it first. Create a new Dockerfile, and install wget in it:

FROM ubuntu:14.04
RUN  apt-get update \
  && apt-get install -y wget \
  && rm -rf /var/lib/apt/lists/*

Then, build that image:

docker build -t my-ubuntu .

Finally, run it:

docker run my-ubuntu wget https://downloads-packages.s3.amazonaws.com/ubuntu-14.04/gitlab_7.8.2-omnibus.1-1_amd64.deb

As a similar approach to the accepted answer that might be considered a bit more readable, elegant, and general (YMMV), you can leverage the map method:

# OP example
df['var3'].map(lambda n: '{:,.2%}'.format(n))

# also works on a series
series_example.map(lambda n: '{:,.2%}'.format(n))

Performance-wise, this is pretty close (marginally slower) than the OP solution.

As an aside, if you do choose to go the pd.options.display.float_format route, consider using a context manager to handle state per this parallel numpy example.

There is a pandas function that can be applied to DateTime index in pandas data frame.

date = dataframe.index #date is the datetime index
date = dates.strftime('%Y-%m-%d') #this will return you a numpy array, element is string.
dstr = date.tolist() #this will make you numpy array into a list

the element inside the list:

u'1910-11-02'

You might need to replace the 'u'.

There might be some additional arguments that I should put into the previous functions.

Just use double quotes with URL, like: git clone "https://yourRepoUrl"

(It somehow sees that you are using 2 quote marks on start, don't know why).

I was getting the same error => fatal: protocol ''https' is not supported (you can see 2 quote marks on https).

update MyTable set CompanyName = rtrim(CompanyName)

Old thread, I know, but for future reference, the --proxy option is now passed with an "="

Example:

$ sudo pip install --proxy=http://yourproxy:yourport package_name

I found that the best way it to add always the +trace option:

dig SOA +trace stackoverflow.com

It works also with recursive CNAME hosted in different provider. +trace trace imply +norecurse so the result is just for the domain you specify.

import numpy
X = numpy.array(the_big_nested_list_you_had)

It's still not going to do what you want; you have more bugs, like trying to unpack a 3-dimensional shape into two target variables in test.

I had an issue with XCode 10.2 specifying the correct iOS simulator version number, so used:

react-native run-ios --simulator='iPhone X (com.apple.CoreSimulator.SimRuntime.iOS-12-1)'

From Java 8 you can use this simple method for picking a random date from the date picker

List<WebElement> datePickerDays = driver.findElements(By.tagName("td"));
datePickerDays.stream().filter(e->e.getText().equals(whichDateYouWantToClick)).findFirst().get().click();

UPDATE TABLE <tablename> SET <COLUMN=VALUE> WHERE <CONDITION>

Example:

UPDATE TABLE teacher SET teacher_name='NSP' WHERE teacher_id='1'

this is when you have one dictionary list:

import csv
with open('names.csv', 'w') as csvfile:
    fieldnames = ['first_name', 'last_name']
    writer = csv.DictWriter(csvfile, fieldnames=fieldnames)
    writer.writeheader()
    writer.writerow({'first_name': 'Baked', 'last_name': 'Beans'})

You can do it using this class I just made. With this class you can use the Map object like another dictionary(including json serialization) or with the dot notation. I hope help you:

class Map(dict):
    """
    Example:
    m = Map({'first_name': 'Eduardo'}, last_name='Pool', age=24, sports=['Soccer'])
    """
    def __init__(self, *args, **kwargs):
        super(Map, self).__init__(*args, **kwargs)
        for arg in args:
            if isinstance(arg, dict):
                for k, v in arg.iteritems():
                    self[k] = v

        if kwargs:
            for k, v in kwargs.iteritems():
                self[k] = v

    def __getattr__(self, attr):
        return self.get(attr)

    def __setattr__(self, key, value):
        self.__setitem__(key, value)

    def __setitem__(self, key, value):
        super(Map, self).__setitem__(key, value)
        self.__dict__.update({key: value})

    def __delattr__(self, item):
        self.__delitem__(item)

    def __delitem__(self, key):
        super(Map, self).__delitem__(key)
        del self.__dict__[key]

Usage examples:

m = Map({'first_name': 'Eduardo'}, last_name='Pool', age=24, sports=['Soccer'])
# Add new key
m.new_key = 'Hello world!'
print m.new_key
print m['new_key']
# Update values
m.new_key = 'Yay!'
# Or
m['new_key'] = 'Yay!'
# Delete key
del m.new_key
# Or
del m['new_key']

You have to convert the type of your return value of the method to the Generic type which you pass to the method during calling.

    public static T values<T>()
    {
        Random random = new Random();
        int number = random.Next(1, 4);
        return (T)Convert.ChangeType(number, typeof(T));
    }

You need pass a type that is type casteable for the value you return through that method.

If you would want to return a value which is not type casteable to the generic type you pass, you might have to alter the code or make sure you pass a type that is casteable for the return value of method. So, this approach is not reccomended.

There are so many solutions here, and most of them still using manual ways by downloading the package manually.

The easiest solution is actually from Navarasu.

Here is the example; and it fixes the problem quickly.

1. Download and install the package with pip

   python -m pip install webdriver-manager

Example

wolf@linux:~$ python -m pip install webdriver-manager

3. Web browser, which is Firefox in this case will be open.

4. Problem solved. That's it!!!

5. Additional note: If you look at the log above, geckodriver was downloaded automatically from https://github.com/mozilla/geckodriver/releases/download/v0.26.0/geckodriver-v0.26.0-linux64.tar.gz and saved to local directory which is at /home/wolf/.wdm/drivers/geckodriver/linux64/v0.26.0

6. You can also copy this binary and put it in any of your executable directory which can be get from echo $PATH command.

E.g.,

cp /home/$(whoami)/.wdm/drivers/geckodriver/linux64/v0.26.0/geckodriver /home/$(whoami)/.local/bin/

Then, let's try the sample code in https://pypi.org/project/selenium/

from selenium import webdriver

browser = webdriver.Firefox()
browser.get('http://seleniumhq.org/')

7. That's it.

First of all, check whether the API you created in the lamda function is registered with your AWS project or not. For that, go to the API gateway in your AWS console. If it is not registered, register it. This is the main cause of this issue.

You can even see in your aws.export.js file, that there are paths corresponding to your API ['/items'].

Your API must be present there, otherwise it will not append the security token to requests. Just register it in your project cloud-logic in your console for this.

If it's there, then use the above mentioned solution

This is a variation on hexacyanide's answer above. This middleware also handles the 'data' event but does not wait for the data to be consumed before calling 'next'. This way both this middleware and bodyParser may coexist, consuming the stream in parallel.

app.use(function(req, res, next) {
  req.rawBody = '';
  req.setEncoding('utf8');

  req.on('data', function(chunk) { 
    req.rawBody += chunk;
  });

  next();
});
app.use(express.bodyParser());

The difference between getAttribute and getParameter is that getParameter will return the value of a parameter that was submitted by an HTML form or that was included in a query string. getAttribute returns an object that you have set in the request, the only way you can use this is in conjunction with a RequestDispatcher. You use a RequestDispatcher to forward a request to another resource (JSP / Servlet). So before you forward the request you can set an attribute which will be available to the next resource.

If you are generating select tag from ajax, add this inside success function:

$('.chosen').chosen();

Or, If you are generating select tag on clicking add more button then add:

$('.chosen').chosen();

inside the function.

spark.default.parallelism is the default number of partition set by spark which is by default 200. and if you want to increase the number of partition than you can apply the property spark.sql.shuffle.partitions to set number of partition in the spark configuration or while running spark SQL.

Normally this spark.sql.shuffle.partitions it is being used when we have a memory congestion and we see below error: spark error:java.lang.IllegalArgumentException: Size exceeds Integer.MAX_VALUE

so set your can allocate a partition as 256 MB per partition and that you can use to set for your processes.

also If number of partitions is near to 2000 then increase it to more than 2000. As spark applies different logic for partition < 2000 and > 2000 which will increase your code performance by decreasing the memory footprint as data default is highly compressed if >2000.

Java 7 and later

Multiple-exception catches are supported, starting in Java 7.

The syntax is:

try {
     // stuff
} catch (Exception1 | Exception2 ex) {
     // Handle both exceptions
}

The static type of ex is the most specialized common supertype of the exceptions listed. There is a nice feature where if you rethrow ex in the catch, the compiler knows that only one of the listed exceptions can be thrown.

Java 6 and earlier

Prior to Java 7, there are ways to handle this problem, but they tend to be inelegant, and to have limitations.

Approach #1

try {
     // stuff
} catch (Exception1 ex) {
     handleException(ex);
} catch (Exception2 ex) {
     handleException(ex);
}

public void handleException(SuperException ex) {
     // handle exception here
}

This gets messy if the exception handler needs to access local variables declared before the try. And if the handler method needs to rethrow the exception (and it is checked) then you run into serious problems with the signature. Specifically, handleException has to be declared as throwing SuperException ... which potentially means you have to change the signature of the enclosing method, and so on.

Approach #2

try {
     // stuff
} catch (SuperException ex) {
     if (ex instanceof Exception1 || ex instanceof Exception2) {
         // handle exception
     } else {
         throw ex;
     }
}

Once again, we have a potential problem with signatures.

Approach #3

try {
     // stuff
} catch (SuperException ex) {
     if (ex instanceof Exception1 || ex instanceof Exception2) {
         // handle exception
     }
}

If you leave out the else part (e.g. because there are no other subtypes of SuperException at the moment) the code becomes more fragile. If the exception hierarchy is reorganized, this handler without an else may end up silently eating exceptions!

You can fake it like this:

-- with column headings 
select column1, column2 from some_table;

-- without column headings
select column1 as '', column2 as '' from some_table;

The order of execution is:

1. A's constructor
2. B's constructor

The assignment occurs in B's constructor after A's constructor—_super—has been called:

function B() {
    _super.apply(this, arguments);   // MyvirtualMethod called in here
    this.testString = "Test String"; // testString assigned here
}

So the following happens:

var b = new B();     // undefined
b.MyvirtualMethod(); // "Test String"

You will need to change your code to deal with this. For example, by calling this.MyvirtualMethod() in B's constructor, by creating a factory method to create the object and then execute the function, or by passing the string into A's constructor and working that out somehow... there's lots of possibilities.

To set an existing column right/left of another, based on their names:

def df_move_column(df, col_to_move, col_left_of_destiny="", right_of_col_bool=True):
    cols = list(df.columns.values)
    index_max = len(cols) - 1

    if not right_of_col_bool:
        # set left of a column "c", is like putting right of column previous to "c"
        # ... except if left of 1st column, then recursive call to set rest right to it
        aux = cols.index(col_left_of_destiny)
        if not aux:
            for g in [x for x in cols[::-1] if x != col_to_move]:
                df = df_move_column(
                        df, 
                        col_to_move=g, 
                        col_left_of_destiny=col_to_move
                        )
            return df
        col_left_of_destiny = cols[aux - 1]

    index_old = cols.index(col_to_move)
    index_new = 0
    if len(col_left_of_destiny):
        index_new = cols.index(col_left_of_destiny) + 1

    if index_old == index_new:
        return df

    if index_new < index_old:
        index_new = np.min([index_new, index_max])
        cols = (
            cols[:index_new]
            + [cols[index_old]]
            + cols[index_new:index_old]
            + cols[index_old + 1 :]
        )
    else:
        cols = (
            cols[:index_old]
            + cols[index_old + 1 : index_new]
            + [cols[index_old]]
            + cols[index_new:]
        )

    df = df[cols]
    return df

E.g.

cols = list("ABCD")
df2 = pd.DataFrame(np.arange(4)[np.newaxis, :], columns=cols)
for k in cols:
    print(30 * "-")
    for g in [x for x in cols if x != k]:
        df_new = df_move_column(df2, k, g)
        print(f"{k} after {g}:  {df_new.columns.values}")
for k in cols:
    print(30 * "-")
    for g in [x for x in cols if x != k]:
        df_new = df_move_column(df2, k, g, right_of_col_bool=False)
        print(f"{k} before {g}:  {df_new.columns.values}")

Output:

You could map the strings to function pointer using a standard collection; executing the function when a match is found.

EDIT: Using the example in the article I gave the link to in my comment, you can declare a function pointer type:

typedef void (*funcPointer)(int);

and create multiple functions to match the signature:

void String1Action(int arg);
void String2Action(int arg);

The map would be std::string to funcPointer:

std::map<std::string, funcPointer> stringFunctionMap;

Then add the strings and function pointers:

stringFunctionMap.add("string1", &String1Action);

I've not tested any of the code I have just posted, it's off the top of my head :)

just right click on the desired folder and select git-bash Here option it will direct you to that folder and start working hope it will work.

You can delimit your regexp with slashes instead of quotes and then a single backslash to escape the question mark. Try this:

maybe there are some unmerged paths in your git repository that you have to resolve before stashing.

tl;dr

myUtilDate.toInstant()                          // Convert from legacy class to modern. `Instant` is a point on the timeline in UTC.
          .atZone(                              // Adjust from UTC to a particular time zone to determine date. Renders a `ZonedDateTime` object. 
              ZoneId.of( "America/Montreal" )   // Better to specify desired/expected zone explicitly than rely implicitly on the JVM’s current default time zone.
          )                                     // Returns a `ZonedDateTime` object.
          .getMonthValue()                      // Extract a month number. Returns a `int` number.

java.time Details

The Answer by Ortomala Lokni for using java.time is correct. And you should be using java.time as it is a gigantic improvement over the old java.util.Date/.Calendar classes. See the Oracle Tutorial on java.time.

I'll add some code showing how to use java.time without regard to java.util.Date, for when you are starting out with fresh code.

Using java.time in a nutshell… An Instant is a moment on the timeline in UTC. Apply a time zone (ZoneId) to get a ZonedDateTime.

The Month class is a sophisticated enum to represent a month in general. That enum has handy methods such as getting a localized name. And rest assured that the month number in java.time is a sane one, 1-12, not the zero-based nonsense (0-11) found in java.util.Date/.Calendar.

To get the current date-time, time zone is crucial. At any moment the date is not the same around the world. Therefore the month is not the same around the world if near the ending/beginning of the month.

ZoneId zoneId = ZoneId.of( "America/Montreal" );  // Or 'ZoneOffset.UTC'.
ZonedDateTime now = ZonedDateTime.now( zoneId );
Month month = now.getMonth(); 
int monthNumber = month.getValue(); // Answer to the Question.
String monthName = month.getDisplayName( TextStyle.FULL , Locale.CANADA_FRENCH );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

You may exchange java.time objects directly with your database. Use a JDBC driver compliant with JDBC 4.2 or later. No need for strings, no need for java.sql.* classes.

Where to obtain the java.time classes?

• Java SE 8, Java SE 9, Java SE 10, and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and Java SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • Later versions of Android bundle implementations of the java.time classes.
  • For earlier Android (<26), the ThreeTenABP project adapts ThreeTen-Backport (mentioned above). See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

Simple way to compare time is :

$time = date('H:i:s',strtotime("11 PM"));
if($time < date('H:i:s')){
     // your code
}

You have to set "secondary okay" mode to let the mongo shell know that you're allowing reads from a secondary. This is to protect you and your applications from performing eventually consistent reads by accident. You can do this in the shell with:

rs.secondaryOk()

After that you can query normally from secondaries.

A note about "eventual consistency": under normal circumstances, replica set secondaries have all the same data as primaries within a second or less. Under very high load, data that you've written to the primary may take a while to replicate to the secondaries. This is known as "replica lag", and reading from a lagging secondary is known as an "eventually consistent" read, because, while the newly written data will show up at some point (barring network failures, etc), it may not be immediately available.

Edit: You only need to set secondaryOk when querying from secondaries, and only once per session.

You may want to have a look at https://isocpp.org/wiki/faq/pointers-to-members#fnptr-vs-memfnptr-types, especially [33.1] Is the type of "pointer-to-member-function" different from "pointer-to-function"?

Think of a GrantedAuthority as being a "permission" or a "right". Those "permissions" are (normally) expressed as strings (with the getAuthority() method). Those strings let you identify the permissions and let your voters decide if they grant access to something.

You can grant different GrantedAuthoritys (permissions) to users by putting them into the security context. You normally do that by implementing your own UserDetailsService that returns a UserDetails implementation that returns the needed GrantedAuthorities.

Roles (as they are used in many examples) are just "permissions" with a naming convention that says that a role is a GrantedAuthority that starts with the prefix ROLE_. There's nothing more. A role is just a GrantedAuthority - a "permission" - a "right". You see a lot of places in spring security where the role with its ROLE_ prefix is handled specially as e.g. in the RoleVoter, where the ROLE_ prefix is used as a default. This allows you to provide the role names withtout the ROLE_ prefix. Prior to Spring security 4, this special handling of "roles" has not been followed very consistently and authorities and roles were often treated the same (as you e.g. can see in the implementation of the hasAuthority() method in SecurityExpressionRoot - which simply calls hasRole()). With Spring Security 4, the treatment of roles is more consistent and code that deals with "roles" (like the RoleVoter, the hasRole expression etc.) always adds the ROLE_ prefix for you. So hasAuthority('ROLE_ADMIN') means the the same as hasRole('ADMIN') because the ROLE_ prefix gets added automatically. See the spring security 3 to 4 migration guide for futher information.

But still: a role is just an authority with a special ROLE_ prefix. So in Spring security 3 @PreAuthorize("hasRole('ROLE_XYZ')") is the same as @PreAuthorize("hasAuthority('ROLE_XYZ')") and in Spring security 4 @PreAuthorize("hasRole('XYZ')") is the same as @PreAuthorize("hasAuthority('ROLE_XYZ')").

Regarding your use case:

Users have roles and roles can perform certain operations.

You could end up in GrantedAuthorities for the roles a user belongs to and the operations a role can perform. The GrantedAuthorities for the roles have the prefix ROLE_ and the operations have the prefix OP_. An example for operation authorities could be OP_DELETE_ACCOUNT, OP_CREATE_USER, OP_RUN_BATCH_JOBetc. Roles can be ROLE_ADMIN, ROLE_USER, ROLE_OWNER etc.

You could end up having your entities implement GrantedAuthority like in this (pseudo-code) example:

@Entity
class Role implements GrantedAuthority {
    @Id
    private String id;

    @ManyToMany
    private final List<Operation> allowedOperations = new ArrayList<>();

    @Override
    public String getAuthority() {
        return id;
    }

    public Collection<GrantedAuthority> getAllowedOperations() {
        return allowedOperations;
    }
}

@Entity
class User {
    @Id
    private String id;

    @ManyToMany
    private final List<Role> roles = new ArrayList<>();

    public Collection<Role> getRoles() {
        return roles;
    }
}

@Entity
class Operation implements GrantedAuthority {
    @Id
    private String id;

    @Override
    public String getAuthority() {
        return id;
    }
}

The ids of the roles and operations you create in your database would be the GrantedAuthority representation, e.g. ROLE_ADMIN, OP_DELETE_ACCOUNT etc. When a user is authenticated, make sure that all GrantedAuthorities of all its roles and the corresponding operations are returned from the UserDetails.getAuthorities() method.

Example: The admin role with id ROLE_ADMIN has the operations OP_DELETE_ACCOUNT, OP_READ_ACCOUNT, OP_RUN_BATCH_JOB assigned to it. The user role with id ROLE_USER has the operation OP_READ_ACCOUNT.

If an admin logs in the resulting security context will have the GrantedAuthorities: ROLE_ADMIN, OP_DELETE_ACCOUNT, OP_READ_ACCOUNT, OP_RUN_BATCH_JOB

If a user logs it, it will have: ROLE_USER, OP_READ_ACCOUNT

The UserDetailsService would take care to collect all roles and all operations of those roles and make them available by the method getAuthorities() in the returned UserDetails instance.

You should use the python-daemon library, it takes care of everything.

From PyPI: Library to implement a well-behaved Unix daemon process.

If you want to work on a locally modified fork of a gem, the best way to do so is

gem 'pry', path: './pry'

in a Gemfile.

... where ./pry would be the clone of your repository. Simply run bundle install once, and any changes in the gem sources you make are immediately reflected. With gem install pry/pry.gem, the sources are still moved into GEM_PATH and you'll always have to run both bundle gem pry and gem update to test.

First you need to set a reference (Menu: Tools->References) to the Microsoft Excel Object Library then you can access all Excel Objects.

After you added the Reference you have full access to all Excel Objects. You need to add Excel in front of everything for example:

Dim xlApp as Excel.Application

Let's say you added an Excel Workbook Object in your Form and named it xLObject.

Here is how you Access a Sheet of this Object and change a Range

Dim sheet As Excel.Worksheet
Set sheet = xlObject.Object.Sheets(1)
sheet.Range("A1") = "Hello World"

(I copied the above from my answer to this question)

Another way to use Excel in Access is to start Excel through a Access Module (the way shahkalpesh described it in his answer)

Event capturing

When you use event capturing

               | |
---------------| |-----------------
| element1     | |                |
|   -----------| |-----------     |

|   -------------------------     |
|        Event CAPTURING          |
-----------------------------------

the event handler of element1 fires first, the event handler of element2 fires last.

Event bubbling

When you use event bubbling

               / \
---------------| |-----------------
| element1     | |                |

|   -------------------------     |
|        Event BUBBLING           |
-----------------------------------

the event handler of element2 fires first, the event handler of element1 fires last.

Any event taking place in the W3C event model is first captured until it reaches the target element and then bubbles up again.

-----------------| |--| |-----------------
| element1       | |  | |                |

Interface

From w3.org, for event capture:

If the capturing EventListener wishes to prevent further processing of the event from occurring it may call the stopPropagation method of the Event interface. This will prevent further dispatch of the event, although additional EventListeners registered at the same hierarchy level will still receive the event. Once an event's stopPropagation method has been called, further calls to that method have no additional effect. If no additional capturers exist and stopPropagation has not been called, the event triggers the appropriate EventListeners on the target itself.

For event bubbling:

Any event handler may choose to prevent further event propagation by calling the stopPropagation method of the Event interface. If any EventListener calls this method, all additional EventListeners on the current EventTarget will be triggered but bubbling will cease at that level. Only one call to stopPropagation is required to prevent further bubbling.

For event cancelation:

Cancelation is accomplished by calling the Event's preventDefault method. If one or more EventListeners call preventDefault during any phase of event flow the default action will be canceled.

Examples

In the following examples, a click on the hyperlink in the web browser triggers the event's flow (the event listeners are executed) and the event target's default action (a new tab is opened).

HTML:

<div id="a">
  <a id="b" href="http://www.google.com/" target="_blank">Google</a>
</div>
<p id="c"></p>

JavaScript:

var el = document.getElementById("c");

function capturingOnClick1(ev) {
    el.innerHTML += "DIV event capture<br>";
}

function capturingOnClick2(ev) {
    el.innerHTML += "A event capture<br>";
}

function bubblingOnClick1(ev) {
    el.innerHTML += "DIV event bubbling<br>";
}

function bubblingOnClick2(ev) {
    el.innerHTML += "A event bubbling<br>";
}

// The 3rd parameter useCapture makes the event listener capturing (false by default)
document.getElementById("a").addEventListener("click", capturingOnClick1, true);
document.getElementById("b").addEventListener("click", capturingOnClick2, true);
document.getElementById("a").addEventListener("click", bubblingOnClick1, false);
document.getElementById("b").addEventListener("click", bubblingOnClick2, false);

Example 1: it results in the output

DIV event capture
A event capture
A event bubbling
DIV event bubbling

Example 2: adding stopPropagation() to the function

function capturingOnClick1(ev) {
    el.innerHTML += "DIV event capture<br>";
    ev.stopPropagation();
}

results in the output

DIV event capture

The event listener prevented further downward and upward propagation of the event. However it did not prevent the default action (a new tab opening).

Example 3: adding stopPropagation() to the function

function capturingOnClick2(ev) {
    el.innerHTML += "A event capture<br>";
    ev.stopPropagation();
}

or the function

function bubblingOnClick2(ev) {
    el.innerHTML += "A event bubbling<br>";
    ev.stopPropagation();
}

results in the output

DIV event capture
A event capture
A event bubbling

This is because both event listeners are registered on the same event target. The event listeners prevented further upward propagation of the event. However they did not prevent the default action (a new tab opening).

Example 4: adding preventDefault() to any function, for instance

function capturingOnClick1(ev) {
    el.innerHTML += "DIV event capture<br>";
    ev.preventDefault();
}

prevents a new tab from opening.

Thanks to Gruff Bunny and Louis' comments, I found the source of the issue.

As I use Backbone.js too, I loaded a special build of Lodash compatible with Backbone and Underscore that disables some features. In this example:

var clone = _.clone(data, true);

data[1].values.d = 'x';

• with the Normal build: _.isEqual(data, clone) === false
• with the Underscore build: _.isEqual(data, clone) === true

I just replaced the Underscore build with the Normal build in my Backbone application and the application is still working. So I can now use the Lodash .clone with the expected behaviour.

Edit 2018: the Underscore build doesn't seem to exist anymore. If you are reading this in 2018, you could be interested by this documentation (Backbone and Lodash).

I have been implementing installation without user consent recently - it was a kiosk application for API level 21+ where I had full control over environment.

The basic requirements are

• API level 21+
• root access to install the updater as a system privileged app.

The following method reads and installs APK from InputStream:

public static boolean installPackage(Context context, InputStream in, String packageName)
            throws IOException {
        PackageInstaller packageInstaller = context.getPackageManager().getPackageInstaller();
        PackageInstaller.SessionParams params = new PackageInstaller.SessionParams(
                PackageInstaller.SessionParams.MODE_FULL_INSTALL);
        params.setAppPackageName(packageName);
        // set params
        int sessionId = packageInstaller.createSession(params);
        PackageInstaller.Session session = packageInstaller.openSession(sessionId);
        OutputStream out = session.openWrite("COSU", 0, -1);
        byte[] buffer = new byte[65536];
        int c;
        while ((c = in.read(buffer)) != -1) {
            out.write(buffer, 0, c);
        }
        session.fsync(out);
        in.close();
        out.close();

        Intent intent = new Intent(context, MainActivity.class);
        intent.putExtra("info", "somedata");  // for extra data if needed..

        Random generator = new Random();

        PendingIntent i = PendingIntent.getActivity(context, generator.nextInt(), intent,PendingIntent.FLAG_UPDATE_CURRENT);
            session.commit(i.getIntentSender());


        return true;
    }

The following code calls the installation

 try {
     InputStream is = getResources().openRawResource(R.raw.someapk_source);
                    installPackage(MainActivity.this, is, "com.example.apk");
     } catch (IOException e) {
                    Toast.makeText(MainActivity.this, e.getMessage(), Toast.LENGTH_SHORT).show();
     }

for the whole thing to work you desperately need INSTALL_PACKAGES permission, or the code above will fail silently

<uses-permission
        android:name="android.permission.INSTALL_PACKAGES" />

to get this permission you must install your APK as System application which REQUIRES root (however AFTER you have installed your updater application it seem to work WITHOUT root)

To install as system application I created a signed APK and pushed it with

adb push updater.apk /sdcard/updater.apk

and then moved it to system/priv-app - which requires remounting FS (this is why the root is required)

adb shell
su
mount -o rw,remount /system
mv /sdcard/updater.apk /system/priv-app
chmod 644 /system/priv-app/updater.apk

for some reason it didn't work with simple debug version, but logcat shows useful info if your application in priv-app is not picked up for some reason.

Since the values are unique, it should be possible to add the values as an additional set of keys. This could be done with the following shortcut.

var foo = {};
foo[foo.apple = "an apple"] = "apple";
foo[foo.pear = "a pear"] = "pear";

This would permit retrieval either via the key or the value:

var key = "apple";
var value = "an apple";

console.log(foo[value]); // "apple"
console.log(foo[key]); // "an apple"

This does assume that there are no common elements between the keys and values.

When you decide between fixed width and fluid width you need to think in terms of your ENTIRE page. Generally, you want to pick one or the other, but not both. The examples you listed in your question are, in-fact, in the same fixed-width page. In other words, the Scaffolding page is using a fixed-width layout. The fixed grid and fluid grid on the Scaffolding page are not meant to be examples, but rather the documentation for implementing fixed and fluid width layouts.

The proper fixed width example is here. The proper fluid width example is here.

When observing the fixed width example, you should not see the content changing sizes when your browser is greater than 960px wide. This is the maximum (fixed) width of the page. Media queries in a fixed-width design will designate the minimum widths for particular styles. You will see this in action when you shrink your browser window and see the layout snap to a different size.

Conversely, the fluid-width layout will always stretch to fit your browser window, no matter how wide it gets. The media queries indicate when the styles change, but the width of containers are always a percentage of your browser window (rather than a fixed number of pixels).

The 'responsive' media queries are all ready to go. You just need to decide if you want to use a fixed width or fluid width layout for your page.

Previously, in bootstrap 2, you had to use row-fluid inside a fluid container and row inside a fixed container. With the introduction of bootstrap 3, row-fluid was removed, do no longer use it.

EDIT: As per the comments, some jsFiddles for:

• fluid non-responsive layout,
• fluid responsive layout,
• fixed non-responsive layout,
• fixed responsive layout.

These fiddles are completely Bootstrap-free, based on pure CSS media queries, which makes them a good starting point, for anyone willing to craft similar solution without using Twitter Bootstrap.

I had problems installing the 64-bit version of MySQLdb on Windows via Pip (problem compiling sources) [32bit version installed ok]. Managed to install the compiled MySQLdb from the .whl file available from http://www.lfd.uci.edu/~gohlke/pythonlibs/

The .whl file can then be installed via pip as document in https://pip.pypa.io/en/latest/user_guide/#installing-from-wheels

For example if you save in C:/ the you can install via

pip install c:/MySQL_python-1.2.5-cp27-none-win_amd64.whl

Follow-up: if you have a 64bit version of Python installed, then you want to install the 64-bit AMD version of MySQLdb from the link above [i.e. even if you have a Intel processor]. If you instead try and install the 32-bit version, I think you get the unsupported wheel error in comments below.

You can use PyPdf2s PdfMerger class.

File Concatenation

You can simply concatenate files by using the append method.

from PyPDF2 import PdfFileMerger

pdfs = ['file1.pdf', 'file2.pdf', 'file3.pdf', 'file4.pdf']

merger = PdfFileMerger()

for pdf in pdfs:
    merger.append(pdf)

merger.write("result.pdf")
merger.close()

You can pass file handles instead file paths if you want.

File Merging

If you want more fine grained control of merging there is a merge method of the PdfMerger, which allows you to specify an insertion point in the output file, meaning you can insert the pages anywhere in the file. The append method can be thought of as a merge where the insertion point is the end of the file.

e.g.

merger.merge(2, pdf)

Here we insert the whole pdf into the output but at page 2.

Page Ranges

If you wish to control which pages are appended from a particular file, you can use the pages keyword argument of append and merge, passing a tuple in the form (start, stop[, step]) (like the regular range function).

e.g.

merger.append(pdf, pages=(0, 3))    # first 3 pages
merger.append(pdf, pages=(0, 6, 2)) # pages 1,3, 5

If you specify an invalid range you will get an IndexError.

Note: also that to avoid files being left open, the PdfFileMergers close method should be called when the merged file has been written. This ensures all files are closed (input and output) in a timely manner. It's a shame that PdfFileMerger isn't implemented as a context manager, so we can use the with keyword, avoid the explicit close call and get some easy exception safety.

You might also want to look at the pdfcat script provided as part of pypdf2. You can potentially avoid the need to write code altogether.

The PyPdf2 github also includes some example code demonstrating merging.

I've created the following script and it worked for me just fine.

#! /bin/sh
cd $(dirname $0)
DB=$1
DBUSER=$2
DBPASSWD=$3
FILE=$DB-$(date +%F).sql
mysqldump --routines "--user=${DBUSER}"  --password=$DBPASSWD $DB > $PWD/$FILE
gzip $FILE
echo Created $PWD/$FILE*

and you call the script using command line arguments.

backupdb.sh my_db dev_user dev_password

$yourArray = file("pathToFile.txt", FILE_IGNORE_NEW_LINES);

FILE_IGNORE_NEW_LINES avoid to add newline at the end of each array element
You can also use FILE_SKIP_EMPTY_LINES to Skip empty lines

reference here

You just have to define that Animal implements Comparable<Animal> i.e. public class Animal implements Comparable<Animal>. And then you have to implement the compareTo(Animal other) method that way you like it.

@Override
public int compareTo(Animal other) {
    return Integer.compare(this.year_discovered, other.year_discovered);
}

Using this implementation of compareTo, animals with a higher year_discovered will get ordered higher. I hope you get the idea of Comparable and compareTo with this example.

Update with psycopg2 2.7:

The classic executemany() is about 60 times slower than @ant32 's implementation (called "folded") as explained in this thread: https://www.postgresql.org/message-id/20170130215151.GA7081%40deb76.aryehleib.com

This implementation was added to psycopg2 in version 2.7 and is called execute_values():

from psycopg2.extras import execute_values
execute_values(cur,
    "INSERT INTO test (id, v1, v2) VALUES %s",
    [(1, 2, 3), (4, 5, 6), (7, 8, 9)])

Previous Answer:

To insert multiple rows, using the multirow VALUES syntax with execute() is about 10x faster than using psycopg2 executemany(). Indeed, executemany() just runs many individual INSERT statements.

@ant32 's code works perfectly in Python 2. But in Python 3, cursor.mogrify() returns bytes, cursor.execute() takes either bytes or strings, and ','.join() expects str instance.

So in Python 3 you may need to modify @ant32 's code, by adding .decode('utf-8'):

args_str = ','.join(cur.mogrify("(%s,%s,%s,%s,%s,%s,%s,%s,%s)", x).decode('utf-8') for x in tup)
cur.execute("INSERT INTO table VALUES " + args_str)

Or by using bytes (with b'' or b"") only:

args_bytes = b','.join(cur.mogrify("(%s,%s,%s,%s,%s,%s,%s,%s,%s)", x) for x in tup)
cur.execute(b"INSERT INTO table VALUES " + args_bytes) 

Based on KMier's answer, addresses the comment that this method poses a problem when the field to be padded is not a field, but the outcome of a (possibly complicated) function; the entire function has to be repeated.

Also, this allows for padding a field to the maximum length of its contents.

WITH
cte AS (
  SELECT 'foo' AS value_to_be_padded
  UNION SELECT 'foobar'
),
cte_max AS (
  SELECT MAX(LEN(value_to_be_padded)) AS max_len
)
SELECT
  CONCAT(SPACE(max_len - LEN(value_to_be_padded)), value_to_be_padded AS left_padded,
  CONCAT(value_to_be_padded, SPACE(max_len - LEN(value_to_be_padded)) AS right_padded;

The -fpermissive flag causes the compiler to report some things that are actually errors (but are permitted by some compilers) as warnings, to permit code to compile even if it doesn't conform to the language rules. You really should fix the underlying problem. Post the smallest, compilable code sample that demonstrates the problem.

-fpermissive
Downgrade some diagnostics about nonconformant code from errors to warnings. Thus, using -fpermissive will allow some nonconforming code to compile.

Use COALESCE to avoid that outcome.

SELECT COALESCE(SUM(column),0)
FROM   table
WHERE  ...

Given three tables (one with all numbers, one with all nulls, and one with a mixture):

SQL Fiddle

MySQL 5.5.32 Schema Setup:

CREATE TABLE foo
(
  id    INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
  val   INT
);

INSERT INTO foo (val) VALUES
(null),(1),(null),(2),(null),(3),(null),(4),(null),(5),(null),(6),(null);

CREATE TABLE bar

You would want to use equals() since they are objects, and utilize the built in ZERO instance:

if (selectPrice.equals(BigDecimal.ZERO))

Note that .equals() takes scale into account, so unless selectPrice is the same scale (0) as .ZERO then this will return false.

To take scale out of the equation as it were:

if (selectPrice.compareTo(BigDecimal.ZERO) == 0)

I should note that for certain mathematical situations, 0.00 != 0, which is why I imagine .equals() takes the scale into account. 0.00 gives precision to the hundredths place, whereas 0 is not that precise. Depending on the situation you may want to stick with .equals().

If you really want to scale an image, do it, but you should resize it before using it. Resizing it at run time will just lose CPU cycles.

This is the category I'm using to scale an image :

UIImage+Extra.h

@interface UIImage (Extras)
- (UIImage *)imageByScalingProportionallyToSize:(CGSize)targetSize;
@end;

UIImage+Extra.m

@implementation UIImage (Extras)

- (UIImage *)imageByScalingProportionallyToSize:(CGSize)targetSize {

UIImage *sourceImage = self;
UIImage *newImage = nil;

CGSize imageSize = sourceImage.size;
CGFloat width = imageSize.width;
CGFloat height = imageSize.height;

CGFloat targetWidth = targetSize.width;
CGFloat targetHeight = targetSize.height;

CGFloat scaleFactor = 0.0;
CGFloat scaledWidth = targetWidth;
CGFloat scaledHeight = targetHeight;

CGPoint thumbnailPoint = CGPointMake(0.0,0.0);

if (!CGSizeEqualToSize(imageSize, targetSize)) {

        CGFloat widthFactor = targetWidth / width;
        CGFloat heightFactor = targetHeight / height;

        if (widthFactor < heightFactor) 
                scaleFactor = widthFactor;
        else
                scaleFactor = heightFactor;

        scaledWidth  = width * scaleFactor;
        scaledHeight = height * scaleFactor;

        // center the image

        if (widthFactor < heightFactor) {
                thumbnailPoint.y = (targetHeight - scaledHeight) * 0.5; 
        } else if (widthFactor > heightFactor) {
                thumbnailPoint.x = (targetWidth - scaledWidth) * 0.5;
        }
}


// this is actually the interesting part:

UIGraphicsBeginImageContextWithOptions(targetSize, NO, 0);

CGRect thumbnailRect = CGRectZero;
thumbnailRect.origin = thumbnailPoint;
thumbnailRect.size.width  = scaledWidth;
thumbnailRect.size.height = scaledHeight;

[sourceImage drawInRect:thumbnailRect];

newImage = UIGraphicsGetImageFromCurrentImageContext();
UIGraphicsEndImageContext();

if(newImage == nil) NSLog(@"could not scale image");


return newImage ;
}

@end

You can use it to the size you want. Like :

[self.itemImageButton setImage:[stretchImage imageByScalingProportionallyToSize:CGSizeMake(20,20)]];

The trick is to add both max-height: 100%; and max-width: 100%; to .container img. Example CSS:

.container {
  width: 300px;
  border: dashed blue 1px;
}

.container img {
  max-height: 100%;
  max-width: 100%;
}

In this way, you can vary the specified width of .container in whatever way you want (200px or 10% for example), and the image will be no larger than its natural dimensions. (You could specify pixels instead of 100% if you didn't want to rely on the natural size of the image.)

Here's the whole fiddle: http://jsfiddle.net/KatieK/Su28P/1/

Using some simple command line (bash scripting):

$ cat /dev/urandom | tr -cd 'a-z0-9,.?/\-' | head -c 30 | xargs
t315,qeqaszwz6kxv?761rf.cj/7gc

$ cat /dev/urandom | tr -cd 'a-z0-9,.?/\-' | head -c 1 | xargs
f

• cat /dev/urandom: get a random stream of char from the kernel
• tr: keep only char char we want
• head: take only the first n chars
• xargs: just for adding a '\n' char

Seems like getTime is not function on above answer.

Update

My recomendation would be to shred the XML into relations and do searches and joins on the resulted relation, in a set oriented fashion, rather than the procedural fashion of searching specific nodes in the XML. Here is a simple XML query that shreds out the nodes and attributes of interest:

select x.value(N'../../../../@stepId', N'int') as StepID
  , x.value(N'../../@id', N'int') as ComponentID
  , x.value(N'@nom',N'nvarchar(100)') as Nom
  , x.value(N'@valeur', N'nvarchar(100)') as Valeur
from @x.nodes(N'/xml/box/components/component/variables/variable') t(x)

However, if you must use an XPath that retrieves exactly the value of interest:

select x.value(N'@valeur', N'nvarchar(100)') as Valeur
from @x.nodes(N'/xml/box[@stepId=sql:variable("@stepID")]/
    components/component[@id = sql:variable("@componentID")]/
       variables/variable[@nom="Enabled"]') t(x)

If the stepID and component ID are columns, not variables, the you should use sql:column() instead of sql:variable in the XPath filters. See Binding Relational Data Inside XML Data.

And finaly if all you need is to check for existance you can use the exist() XML method:

select @x.exist(
  N'/xml/box[@stepId=sql:variable("@stepID")]/
    components/component[@id = sql:variable("@componentID")]/
      variables/variable[@nom="Enabled" and @valeur="Yes"]') 

Just a note that all the above may not work for you with tomcat7 unless you've also done this:

sudo apt-get install tomcat7-admin

You can reference the image using relative path:

<img src="../images/logo.png">
          __ ______ ________
          |    |       |
          |    |       |___ 3. Get the file named "logo.png"
          |    |
          |    |___ 2. Go inside "images/" subdirectory
          | 
          | 
          |____ 1. Go one level up

Or you can use absolute path: / means that this is an absolute path on the server, So if your server is at https://example.org/, referencing /images/logo.png from any page would point to https://example.org/images/logo.png

<img src="/images/logo.png">
          |______ ________
          |    |       |
          |    |       |___ 3. Get the file named "logo.png"
          |    |
          |    |___ 2. Go inside "images/" subdirectory
          | 
          | 
          |____ 1. Go to the root folder

Could you try this out?

=IIF((Fields!OpeningStock.Value=0) AND (Fields!GrossDispatched.Value=0) AND 
(Fields!TransferOutToMW.Value=0) AND (Fields!TransferOutToDW.Value=0) AND 
(Fields!TransferOutToOW.Value=0) AND (Fields!NetDispatched.Value=0) AND (Fields!QtySold.Value=0) 
AND (Fields!StockAdjustment.Value=0) AND (Fields!ClosingStock.Value=0),True,False)

Note: Setting Hidden to False will make the row visible

You will not write code into a static block that needs to be invoked anywhere in your program. If the purpose of the code is to be invoked then you must place it in a method.

You can write static initializer blocks to initialize static variables when the class is loaded but this code can be more complex..

A static initializer block looks like a method with no name, no arguments, and no return type. Since you never call it it doesn't need a name. The only time its called is when the virtual machine loads the class.

You might want to check out RFC 6570. This URI Template spec shows many examples of how urls can contain parameters.

Given that you're only converting to ints to then perform a comparison, I'd just switch the table definition around to using varchar also:

Create table #myTempTable
(
num varchar(12)
)
insert into #myTempTable (num) values (1),(2),(3),(4),(5)

and remove all of the attempted CONVERTs from the rest of the query.

 SELECT a.name, a.value AS value, COUNT(*) AS pocet   
 FROM 
 (SELECT item.name, value.value 
  FROM mdl_feedback AS feedback 
  INNER JOIN mdl_feedback_item AS item 
       ON feedback.id = item.feedback
  INNER JOIN mdl_feedback_value AS value 
       ON item.id = value.item 
   WHERE item.typ = 'multichoicerated' AND item.feedback IN (43)
 ) AS a 
 INNER JOIN #myTempTable 
     on a.value = #myTempTable.num
 GROUP BY a.name, a.value ORDER BY a.name

To remove everything before the first /

input = input.Substring(input.IndexOf("/"));

To remove everything after the first /

input = input.Substring(0, input.IndexOf("/") + 1);

To remove everything before the last /

input = input.Substring(input.LastIndexOf("/"));

To remove everything after the last /

input = input.Substring(0, input.LastIndexOf("/") + 1);

An even more simpler solution for removing characters after a specified char is to use the String.Remove() method as follows:

To remove everything after the first /

input = input.Remove(input.IndexOf("/") + 1);

To remove everything after the last /

input = input.Remove(input.LastIndexOf("/") + 1);

I think this is what you are looking for -

select Address1+Address2 as CompleteAddress from YourTable
where Address1+Address2 like '%YourSearchString%'

To prevent a compound word being created when we append address1 with address2, you can use this -

select Address1 + ' ' + Address2 as CompleteAddress from YourTable 
where Address1 + ' ' + Address2 like '%YourSearchString%'

So, '123 Center St' and 'Apt 3B' will not be '123 Center StApt 3B' but will be '123 Center St Apt 3B'.

It is normally provided by the browser and hard to change, so the only way around it will be a CSS/JavaScript hack,

See the following links for some approaches:

You can create table variable instead of tamp table in procedure A and execute procedure B and insert into temp table by below query.

DECLARE @T TABLE
(
TABLE DEFINITION
)
.
.
.
INSERT INTO @T
EXEC B @MYDATE

and you continue operation.

If you want a variable to be accessible across the entire page, it works well to define it at the top of the file. (You can use either an implicit or explicit type.)

@{
    // implicit type
    var something1 = "something";

    // explicit type
    string something2 = "something";
}

<div>@something1</div> @*display first variable*@
<div>@something2</div> @*display second variable*@

You may want to use the "xcode-select" command in terminal to switch between the different Xcode version in the installed folders.

I'v been used following code in IE. (IE8 compatible)

var dString = "2013.2.4";
var myDate = new Date( dString.replace(/(\d+)\.(\d+)\.(\d+)/,"$2/$3/$1") );
alert( "my date:"+ myDate );

• If you need to compare only day of month value than you can use the following code:

  if yourdate.day == datetime.today().day:
      # do something
  

• If you need to check that the difference between two dates is acceptable then you can use timedelta:

  if (datetime.today() - yourdate).days == 0:
      #do something
  

• And if you want to compare date part only than you can simply use:

  from datetime import datetime, date
  if yourdatetime.date() < datetime.today().date()
      # do something
  

Note that timedelta has the following format:

datetime.timedelta([days[, seconds[, microseconds[, milliseconds[, minutes[, hours[, weeks]]]]]]])

So you are able to check diff in days, seconds, msec, minutes and so on depending on what you really need:

from datetime import datetime
if (datetime.today() - yourdate).days == 0:
    #do something

In your case when you need to check that two dates are exactly the same you can use timedelta(0):

from datetime import datetime, timedelta
if (datetime.today() - yourdate) == timedelta(0):
    #do something

UPDATE:

If you want to take advantage of Imagick (if it is installed on your server). Note: I didn't use Imagick's nature writeFile because I was having issues with it on my server. File put contents works just as well.

<?php
/**
 * 
 * Generate Thumbnail using Imagick class
 *  
 * @param string $img
 * @param string $width
 * @param string $height
 * @param int $quality
 * @return boolean on true

 * @throws ImagickException
 */
function generateThumbnail($img, $width, $height, $quality = 90)
{
    if (is_file($img)) {
        $imagick = new Imagick(realpath($img));
        $imagick->setImageFormat('jpeg');
        $imagick->setImageCompression(Imagick::COMPRESSION_JPEG);
        $imagick->setImageCompressionQuality($quality);
        $imagick->thumbnailImage($width, $height, false, false);
        $filename_no_ext = reset(explode('.', $img));
        if (file_put_contents($filename_no_ext . '_thumb' . '.jpg', $imagick) === false) {
            throw new Exception("Could not put contents.");
        }
        return true;
    }
    else {
        throw new Exception("No valid image provided with {$img}.");
    }
}

// example usage
try {
    generateThumbnail('test.jpg', 100, 50, 65);
}
catch (ImagickException $e) {
    echo $e->getMessage();
}
catch (Exception $e) {
    echo $e->getMessage();
}
?>

I have been using this, just execute the function after you store the original image and use that location to create the thumbnail. Edit it to your liking...

function makeThumbnails($updir, $img, $id)
{
    $thumbnail_width = 134;
    $thumbnail_height = 189;
    $thumb_beforeword = "thumb";
    $arr_image_details = getimagesize("$updir" . $id . '_' . "$img"); // pass id to thumb name
    $original_width = $arr_image_details[0];
    $original_height = $arr_image_details[1];
    if ($original_width > $original_height) {
        $new_width = $thumbnail_width;
        $new_height = intval($original_height * $new_width / $original_width);
    } else {
        $new_height = $thumbnail_height;
        $new_width = intval($original_width * $new_height / $original_height);
    }
    $dest_x = intval(($thumbnail_width - $new_width) / 2);
    $dest_y = intval(($thumbnail_height - $new_height) / 2);
    if ($arr_image_details[2] == IMAGETYPE_GIF) {
        $imgt = "ImageGIF";
        $imgcreatefrom = "ImageCreateFromGIF";
    }
    if ($arr_image_details[2] == IMAGETYPE_JPEG) {
        $imgt = "ImageJPEG";
        $imgcreatefrom = "ImageCreateFromJPEG";
    }
    if ($arr_image_details[2] == IMAGETYPE_PNG) {
        $imgt = "ImagePNG";
        $imgcreatefrom = "ImageCreateFromPNG";
    }
    if ($imgt) {
        $old_image = $imgcreatefrom("$updir" . $id . '_' . "$img");
        $new_image = imagecreatetruecolor($thumbnail_width, $thumbnail_height);
        imagecopyresized($new_image, $old_image, $dest_x, $dest_y, 0, 0, $new_width, $new_height, $original_width, $original_height);
        $imgt($new_image, "$updir" . $id . '_' . "$thumb_beforeword" . "$img");
    }
}

The above function creates images with a uniform thumbnail size. If the image doesn't have the same dimensions as the specified thumbnail size (proportionally), it just has blackspace on the top and bottom.

Try this:

return( (str).Remove(str.Length-1) );

There's JS function to deal with &#xxxx styled entities:
function at GitHub

// encode(decode) html text into html entity
var decodeHtmlEntity = function(str) {
  return str.replace(/&#(\d+);/g, function(match, dec) {
    return String.fromCharCode(dec);
  });
};

var encodeHtmlEntity = function(str) {
  var buf = [];
  for (var i=str.length-1;i>=0;i--) {
    buf.unshift(['&#', str[i].charCodeAt(), ';'].join(''));
  }
  return buf.join('');
};

var entity = '高级程序设计';
var str = '??????';
console.log(decodeHtmlEntity(entity) === str);
console.log(encodeHtmlEntity(str) === entity);
// output:
// true
// true

Another useful solution, you can work with this string as array of String

for (String s : "xyz".split("")) {
    System.out.println(s);
}

i had a similar situation and i used the below code for getting this worked..

Aspose.Cells.LoadOptions loadOptions = new Aspose.Cells.LoadOptions(Aspose.Cells.LoadFormat.CSV);

Workbook workbook = new Workbook(fstream, loadOptions);

Worksheet worksheet = workbook.Worksheets[0];

dt = worksheet.Cells.ExportDataTable(0, 0, worksheet.Cells.MaxDisplayRange.RowCount, worksheet.Cells.MaxDisplayRange.ColumnCount, true);

DataTable dtCloned = dt.Clone();
ArrayList myAL = new ArrayList();

foreach (DataColumn column in dtCloned.Columns)
{
    if (column.DataType == Type.GetType("System.DateTime"))
    {
        column.DataType = typeof(String);
        myAL.Add(column.ColumnName);
    }
}


foreach (DataRow row in dt.Rows)
{
    dtCloned.ImportRow(row);
}



foreach (string colName in myAL)
{
    dtCloned.Columns[colName].Convert(val => DateTime.Parse(Convert.ToString(val)).ToString("MMMM dd, yyyy"));
}


/*******************************/

public static class MyExtension

    {
        foreach (DataRow row in column.Table.Rows)
        {
            row[column] = conversion(row[column]);
        }
    }
}

Hope this helps some1 thx_joxin

You can simply do that by setting target="_blank", w3schools has an example.

The docs mention train_test_split is just a convenience function on top of shuffle split.

I just rearranged some of their code to make my own example. Note the actual solution is the middle block of code. The rest is imports, and setup for a runnable example.

from sklearn.model_selection import ShuffleSplit
from sklearn.utils import safe_indexing, indexable
from itertools import chain
import numpy as np
X = np.reshape(np.random.randn(20),(10,2)) # 10 training examples
y = np.random.randint(2, size=10) # 10 labels
seed = 1

cv = ShuffleSplit(random_state=seed, test_size=0.25)
arrays = indexable(X, y)
train, test = next(cv.split(X=X))
iterator = list(chain.from_iterable((
    safe_indexing(a, train),
    safe_indexing(a, test),
    train,
    test
    ) for a in arrays)
)
X_train, X_test, train_is, test_is, y_train, y_test, _, _  = iterator

print(X)
print(train_is)
print(X_train)

Now I have the actual indexes: train_is, test_is

You should check for Dictionary.ContainsKey(int key) before trying to pull out the value.

Dictionary<int, int> myDictionary = new Dictionary<int, int>();
myDictionary.Add(2,4);
myDictionary.Add(3,5);

int keyToFind = 7;
if(myDictionary.ContainsKey(keyToFind))
{
    myValueLookup = myDictionay[keyToFind];
    // do work...
}
else
{
    // the key doesn't exist.
}

And in swift we can do

UIApplication.sharedApplication().sendAction("resignFirstResponder", to: nil, from: nil, forEvent: nil)

As a CS student, you might have heard about Mathematical induction. The recursive solution of Tower of Hanoi works analogously - only different part is to really get not lost with B and C as were the full tower ends up.

For this problem, Greedy approach gives a better solution than DP or others. Greedy approach: Find the largest denomination that is lesser than the required value and add it to the set of coins to be delivered. Lower the required cents by the denomination just added and repeat until the required cents becomes zero.

My solution (greedy approach) in java solution:

public class MinimumCoinDenomination {

    private static final int[] coinsDenominations = {1, 5, 10, 25, 50, 100};

    public static Map<Integer, Integer> giveCoins(int requiredCents) {
        if(requiredCents <= 0) {
            return null;
        }
        Map<Integer, Integer> denominations = new HashMap<Integer, Integer>();

        int dollar = requiredCents/100;
        if(dollar>0) {
            denominations.put(100, dollar);
        }
        requiredCents = requiredCents - (dollar * 100);

        //int sum = 0;
        while(requiredCents > 0) {
            for(int i = 1; i<coinsDenominations.length; i++) {
                if(requiredCents < coinsDenominations[i]) {
                    //sum = sum +coinsDenominations[i-1];
                    if(denominations.containsKey(coinsDenominations[i-1])) {
                        int c = denominations.get(coinsDenominations[i-1]);
                        denominations.put(coinsDenominations[i-1], c+1);
                    } else {
                        denominations.put(coinsDenominations[i-1], 1);
                    }
                    requiredCents = requiredCents - coinsDenominations[i-1];
                    break;
                }
            }
        }
        return denominations;
    }

    public static void main(String[] args) {
        System.out.println(giveCoins(199));
    }

None of these answers are working (date today 9th Dec 2018). The correct resolution here is to add .table-responsive-sm to your table:

<table class='table table-responsive-sm'>
[Your table]
</table>

This applies the responsiveness aspect only to the SM view (mobile). So in mobile view you get the scrolling as desired and in larger views the table is not responsive and thus displayed full width, as desired.

Docs: https://getbootstrap.com/docs/4.0/content/tables/#breakpoint-specific

As of SLF4J 1.6.0, in the presence of multiple parameters and if the last argument in a logging statement is an exception, then SLF4J will presume that the user wants the last argument to be treated as an exception and not a simple parameter. See also the relevant FAQ entry.

So, writing (in SLF4J version 1.7.x and later)

 logger.error("one two three: {} {} {}", "a", "b", 
              "c", new Exception("something went wrong"));

or writing (in SLF4J version 1.6.x)

 logger.error("one two three: {} {} {}", new Object[] {"a", "b", 
              "c", new Exception("something went wrong")});

will yield

one two three: a b c
java.lang.Exception: something went wrong
    at Example.main(Example.java:13)
    at java.lang.reflect.Method.invoke(Method.java:597)
    at ...

The exact output will depend on the underlying framework (e.g. logback, log4j, etc) as well on how the underlying framework is configured. However, if the last parameter is an exception it will be interpreted as such regardless of the underlying framework.

In my case, I was transport class component from parent and use it inside as a prop var, using typescript and Formik, and run well like this:

Parent 1

import Parent2 from './../components/Parent2/parent2'
import Parent3 from './../components/Parent3/parent3'

export default class Parent1 extends React.Component {
  render(){
    <React.Fragment>
      <Parent2 componentToFormik={Parent3} />
    </React.Fragment>
  }
}

Parent 2

export default class Parent2 extends React.Component{
  render(){
    const { componentToFormik } = this.props
    return(
    <Formik 
      render={(formikProps) => {
        return(
          <React.fragment>
            {(new componentToFormik(formikProps)).render()}
          </React.fragment>
        )
      }}
    />
    )
  }
}

It depends on the nature of your application. And, since you did not describe it in great detail, it is an impossible question to answer. I find Backbone to be the easiest, but I work in Angular all day. Performance is more up to the coder than the framework, in my opinion.

Are you doing heavy DOM manipulation? I would use jQuery and Backbone.

Very data driven app? Angular with its nice data binding.

Game programming? None - direct to canvas; maybe a game engine.

If you see then logical difference between these two is Comparator in Java compare two objects provided to him, while Comparable interface compares "this" reference with the object specified.

Comparable in Java is used to implement natural ordering of object. In Java API String, Date and wrapper classes implement Comparable interface.

If any class implement Comparable interface in Java then collection of that object either List or Array can be sorted automatically by using Collections.sort() or Array.sort() method and object will be sorted based on there natural order defined by compareTo method.

Objects which implement Comparable in Java can be used as keys in a sorted map or elements in a sorted set for example TreeSet, without specifying any Comparator.

Boost test offers the following usage recommendations for Visual Studio that would enable you to run the unit tests automatically at the end of compilation and capture the output into the build window.

The nice side effect of this trick is it enable you to treat test failures as compilation errors. "...you could jump through these errors using usual keyboard shortcuts/mouse clicks you use for compilation error analysis..."

1. Use the 'jet' colormap for a transition between blue and red.
2. Use pcolor() with the vmin, vmax parameters.

CloseableHttpClient is the base class of the httpclient library, the one all implementations use. Other subclasses are for the most part deprecated.

The HttpClient is an interface for this class and other classes.

You should then use the CloseableHttpClient in your code, and create it using the HttpClientBuilder. If you need to wrap the client to add specific behaviour you should use request and response interceptors instead of wrapping with the HttpClient.

This answer was given in the context of httpclient-4.3.

Try looking at the BigDecimal Class. It is the go to class for currency and support accurate rounding.

IIUC you want the number of different ID for every domain, then you can try this:

output = df.drop_duplicates()
output.groupby('domain').size()

output:

    domain
facebook.com    1
google.com      1
twitter.com     2
vk.com          3
dtype: int64

You could also use value_counts, which is slightly less efficient.But the best is Jezrael's answer using nunique:

%timeit df.drop_duplicates().groupby('domain').size()
1000 loops, best of 3: 939 µs per loop
%timeit df.drop_duplicates().domain.value_counts()
1000 loops, best of 3: 1.1 ms per loop
%timeit df.groupby('domain')['ID'].nunique()
1000 loops, best of 3: 440 µs per loop

GitLab's "merge request" feature is equivalent to GitHub's "pull request" feature. Both are means of pulling changes from another branch or fork into your branch and merging the changes with your existing code. They are useful tools for code review and change management.

An article from GitLab discusses the differences in naming the feature:

Merge or pull requests are created in a git management application and ask an assigned person to merge two branches. Tools such as GitHub and Bitbucket choose the name pull request since the first manual action would be to pull the feature branch. Tools such as GitLab and Gitorious choose the name merge request since that is the final action that is requested of the assignee. In this article we'll refer to them as merge requests.

A "merge request" should not be confused with the git merge command. Neither should a "pull request" be confused with the git pull command. Both git commands are used behind the scenes in both pull requests and merge requests, but a merge/pull request refers to a much broader topic than just these two commands.

Sorry to burst your bubble but Spotify desktop client is just a Webkit-based browser. Of course it exposes specific additional functionality, but it's only able to run JS and render HTML/CSS because it has a JS engine as well as a Chromium rendering engine. This does not help you with coding a client-side web-app and deploying to multiple platforms.

What you're looking for is similar to Sencha Touch - a framework that allows for HTML5 apps to be natively deployed to iOS, Android and Blackberry devices. It basically acts as an intermediary between certain API calls and device-specific functionality available.

I have no experience with appcelerator, bit it appears to be doing exactly that - and get very favourable reviews online. You should give it a go (unless you wanted to go back to 1999 and roll with MS HTA ;)

I know StackOverflow is not the place for opinion based answers, but I actually have a good opinion on when to shelve changes with a stash.

You don't want to commit you experimental changes

When you make changes in your workspace/working tree, if you need to perform any branch based operations like a merge, push, fetch or pull, you must be at a clean commit point. So if you have workspace changes you need to commit them. But what if you don't want to commit them? What if they are experimental? Something you don't want part of your commit history? Something you don't want others to see when you push to GitHub?

You don't want to lose local changes with a hard reset

In that case, you can do a hard reset. But if you do a hard reset you will lose all of your local working tree changes because everything gets overwritten to where it was at the time of the last commit and you'll lose all of your changes.

So, as for the answer of 'when should you stash', the answer is when you need to get back to a clean commit point with a synchronized working tree/index/commit, but you don't want to lose your local changes in the process. Just shelve your changes in a stash and you're good.

And once you've done your stash and then merged or pulled or pushed, you can just stash pop or apply and you're back to where you started from.

Git stash and GitHub

GitHub is constantly adding new features, but as of right now, there is now way to save a stash there. Again, the idea of a stash is that it's local and private. Nobody else can peek into your stash without physical access to your workstation. Kinda the same way git reflog is private with the git log is public. It probably wouldn't be private if it was pushed up to GitHub.

One trick might be to do a diff of your workspace, check the diff into your git repository, commit and then push. Then you can do a pull from home, get the diff and then unwind it. But that's a pretty messy way to achieve those results.

git diff > git-dif-file.diff

EDIT 7/1/15:

I wrote this answer a pretty long time ago and haven't been keeping up a lot with angular for a while, but it seems as though this answer is still relatively popular, so I wanted to point out that a couple of the point @nicolas makes below are good. For one, injecting $rootScope and attaching the helpers there will keep you from having to add them for every controller. Also - I agree that if what you're adding should be thought of as Angular services OR filters, they should be adopted into the code in that manner.

Also, as of the current version 1.4.2, Angular exposes a "Provider" API, which is allowed to be injected into config blocks. See these resources for more:

https://docs.angularjs.org/guide/module#module-loading-dependencies

AngularJS dependency injection of value inside of module.config

I don't think I'm going to update the actual code blocks below, because I'm not really actively using Angular these days and I don't really want to hazard a new answer without feeling comfortable that it's actually conforming to new best practices. If someone else feels up to it, by all means go for it.

EDIT 2/3/14:

After thinking about this and reading some of the other answers, I actually think I prefer a variation of the method brought up by @Brent Washburne and @Amogh Talpallikar. Especially if you're looking for utilities like isNotString() or similar. One of the clear advantages here is that you can re-use them outside of your angular code and you can use them inside of your config function (which you can't do with services).

That being said, if you're looking for a generic way to re-use what should properly be services, the old answer I think is still a good one.

What I would do now is:

app.js:

var MyNamespace = MyNamespace || {};

 MyNamespace.helpers = {
   isNotString: function(str) {
     return (typeof str !== "string");
   }
 };

 angular.module('app', ['app.controllers', 'app.services']).                             
   config(['$routeProvider', function($routeProvider) {
     // Routing stuff here...
   }]);

controller.js:

angular.module('app.controllers', []).                                                                                                                                                                                  
  controller('firstCtrl', ['$scope', function($scope) {
    $scope.helpers = MyNamespace.helpers;
  });

Then in your partial you can use:

<button data-ng-click="console.log(helpers.isNotString('this is a string'))">Log String Test</button>

Old answer below:

It might be best to include them as a service. If you're going to re-use them across multiple controllers, including them as a service will keep you from having to repeat code.

If you'd like to use the service functions in your html partial, then you should add them to that controller's scope:

$scope.doSomething = ServiceName.functionName;

Then in your partial you can use:

<button data-ng-click="doSomething()">Do Something</button>

Here's a way you might keep this all organized and free from too much hassle:

Separate your controller, service and routing code/config into three files: controllers.js, services.js, and app.js. The top layer module is "app", which has app.controllers and app.services as dependencies. Then app.controllers and app.services can be declared as modules in their own files. This organizational structure is just taken from Angular Seed:

app.js:

 angular.module('app', ['app.controllers', 'app.services']).                             
   config(['$routeProvider', function($routeProvider) {
     // Routing stuff here...
   }]);  

services.js:

 /* Generic Services */                                                                                                                                                                                                    
 angular.module('app.services', [])                                                                                                                                                                        
   .factory("genericServices", function() {                                                                                                                                                   
     return {                                                                                                                                                                                                              
       doSomething: function() {   
         //Do something here
       },
       doSomethingElse: function() {
         //Do something else here
       }
    });

controller.js:

angular.module('app.controllers', []).                                                                                                                                                                                  
  controller('firstCtrl', ['$scope', 'genericServices', function($scope, genericServices) {
    $scope.genericServices = genericServices;
  });

Then in your partial you can use:

<button data-ng-click="genericServices.doSomething()">Do Something</button>
<button data-ng-click="genericServices.doSomethingElse()">Do Something Else</button>

That way you only add one line of code to each controller and are able to access any of the services functions wherever that scope is accessible.

select substring( field, 1, 5 ) from sometable

You could also do this if you think it's more clear:

if (columnname != a 
  && columnname != b 
  && columnname != c
{
   if (checkbox.checked || columnname != A2)
   {
      "statement 1"
   }
}
