Here is the R version of b-h-'s function, just in case:

measure <- function(lon1,lat1,lon2,lat2) {
    R <- 6378.137                                # radius of earth in Km
    dLat <- (lat2-lat1)*pi/180
    dLon <- (lon2-lon1)*pi/180
    a <- sin((dLat/2))^2 + cos(lat1*pi/180)*cos(lat2*pi/180)*(sin(dLon/2))^2
    c <- 2 * atan2(sqrt(a), sqrt(1-a))
    d <- R * c
    return (d * 1000)                            # distance in meters
}

There are multiple ways to calculate the distance based on the coordinates i.e latitude and longitude

Install and import

from geopy import distance
from math import sin, cos, sqrt, atan2, radians
from sklearn.neighbors import DistanceMetric
import osrm
import numpy as np

Define coordinates

lat1, lon1, lat2, lon2, R = 20.9467,72.9520, 21.1702, 72.8311, 6373.0
coordinates_from = [lat1, lon1]
coordinates_to = [lat2, lon2]

Using haversine

dlon = radians(lon2) - radians(lon1)
dlat = radians(lat2) - radians(lat1)
    
a = sin(dlat / 2)**2 + cos(lat1) * cos(lat2) * sin(dlon / 2)**2
c = 2 * atan2(sqrt(a), sqrt(1 - a))
    
distance_haversine_formula = R * c
print('distance using haversine formula: ', distance_haversine_formula)

Using haversine with sklearn

dist = DistanceMetric.get_metric('haversine')
    
X = [[radians(lat1), radians(lon1)], [radians(lat2), radians(lon2)]]
distance_sklearn = R * dist.pairwise(X)
print('distance using sklearn: ', np.array(distance_sklearn).item(1))

Using OSRM

osrm_client = osrm.Client(host='http://router.project-osrm.org')
coordinates_osrm = [[lon1, lat1], [lon2, lat2]] # note that order is lon, lat
    
osrm_response = osrm_client.route(coordinates=coordinates_osrm, overview=osrm.overview.full)
dist_osrm = osrm_response.get('routes')[0].get('distance')/1000 # in km
print('distance using OSRM: ', dist_osrm)

Using geopy

distance_geopy = distance.distance(coordinates_from, coordinates_to).km
print('distance using geopy: ', distance_geopy)
    
distance_geopy_great_circle = distance.great_circle(coordinates_from, coordinates_to).km 
print('distance using geopy great circle: ', distance_geopy_great_circle)

Output

distance using haversine formula:  26.07547017310917
distance using sklearn:  27.847882224769783
distance using OSRM:  33.091699999999996
distance using geopy:  27.7528030550408
distance using geopy great circle:  27.839182219511834

If you are interested in obtaining a very simplified 'center' of the points (for example, to simply center a map to the center of your gmaps polygon), then here's a basic approach that worked for me.

public function center() {
    $minlat = false;
    $minlng = false;
    $maxlat = false;
    $maxlng = false;
    $data_array = json_decode($this->data, true);
    foreach ($data_array as $data_element) {
        $data_coords = explode(',',$data_element);
        if (isset($data_coords[1])) {
            if ($minlat === false) { $minlat = $data_coords[0]; } else { $minlat = ($data_coords[0] < $minlat) ? $data_coords[0] : $minlat; }
            if ($maxlat === false) { $maxlat = $data_coords[0]; } else { $maxlat = ($data_coords[0] > $maxlat) ? $data_coords[0] : $maxlat; }
            if ($minlng === false) { $minlng = $data_coords[1]; } else { $minlng = ($data_coords[1] < $minlng) ? $data_coords[1] : $minlng; }
            if ($maxlng === false) { $maxlng = $data_coords[1]; } else { $maxlng = ($data_coords[1] > $maxlng) ? $data_coords[1] : $maxlng; }
        }
    }
    $lat = $maxlat - (($maxlat - $minlat) / 2);
    $lng = $maxlng - (($maxlng - $minlng) / 2);
    return $lat.','.$lng;
}

This returns the middle lat/lng coordinate for the center of a polygon.

Loc2country is a Golang based tool that returns the ISO alpha-3 country code for given location coordinates (lat/lon). It responds in microseconds. It uses a geohash to country map.

The geohash data is generated using georaptor.

We use geohash at level 6 for this tool, i.e., boxes of size 1.2km x 600m.

The problem I need to solve is to store contracts containing a few fields (address, book, num_of_days, borrower_addr, blk_data), blk_data is a transaction list (block number and transaction address). This question and answer helped me. I would like to share my code as below. Hope this helps.

1. Schema definition. See blk_data.

var ContractSchema = new Schema(
    {
        address: {type: String, required: true, max: 100},  //contract address
        // book_id: {type: String, required: true, max: 100},  //book id in the book collection
        book: { type: Schema.ObjectId, ref: 'clc_books', required: true }, // Reference to the associated book.
        num_of_days: {type: Number, required: true, min: 1},
        borrower_addr: {type: String, required: true, max: 100},
        // status: {type: String, enum: ['available', 'Created', 'Locked', 'Inactive'], default:'Created'},

        blk_data: [{
            tx_addr: {type: String, max: 100}, // to do: change to a list
            block_number: {type: String, max: 100}, // to do: change to a list
        }]
    }
);

2. Create a record for the collection in the MongoDB. See blk_data.

// Post submit a smart contract proposal to borrowing a specific book.
exports.ctr_contract_propose_post = [

    // Validate fields
    body('book_id', 'book_id must not be empty.').isLength({ min: 1 }).trim(),
    body('req_addr', 'req_addr must not be empty.').isLength({ min: 1 }).trim(),
    body('new_contract_addr', 'contract_addr must not be empty.').isLength({ min: 1 }).trim(),
    body('tx_addr', 'tx_addr must not be empty.').isLength({ min: 1 }).trim(),
    body('block_number', 'block_number must not be empty.').isLength({ min: 1 }).trim(),
    body('num_of_days', 'num_of_days must not be empty.').isLength({ min: 1 }).trim(),

    // Sanitize fields.
    sanitizeBody('*').escape(),
    // Process request after validation and sanitization.
    (req, res, next) => {

        // Extract the validation errors from a request.
        const errors = validationResult(req);
        if (!errors.isEmpty()) {
            // There are errors. Render form again with sanitized values/error messages.
            res.status(400).send({ errors: errors.array() });
            return;
        }

        // Create a Book object with escaped/trimmed data and old id.
        var book_fields =
            {
                _id: req.body.book_id, // This is required, or a new ID will be assigned!
                cur_contract: req.body.new_contract_addr,
                status: 'await_approval'
            };

        async.parallel({
            //call the function get book model
            books: function(callback) {
                Book.findByIdAndUpdate(req.body.book_id, book_fields, {}).exec(callback);
            },
        }, function(error, results) {
            if (error) {
                res.status(400).send({ errors: errors.array() });
                return;
            }

            if (results.books.isNew) {
                // res.render('pg_error', {
                //     title: 'Proposing a smart contract to borrow the book',
                //     c: errors.array()
                // });
                res.status(400).send({ errors: errors.array() });
                return;
            }

            var contract = new Contract(
                {
                    address: req.body.new_contract_addr,
                    book: req.body.book_id,
                    num_of_days: req.body.num_of_days,
                    borrower_addr: req.body.req_addr

                });

            var blk_data = {
                    tx_addr: req.body.tx_addr,
                    block_number: req.body.block_number
                };
            contract.blk_data.push(blk_data);

            // Data from form is valid. Save book.
            contract.save(function (err) {
                if (err) { return next(err); }
                // Successful - redirect to new book record.
                resObj = {
                    "res": contract.url
                };
                res.status(200).send(JSON.stringify(resObj));
                // res.redirect();
            });

        });

    },
];

3. Update a record. See blk_data.

// Post lender accept borrow proposal.
exports.ctr_contract_propose_accept_post = [

    // Validate fields
    body('book_id', 'book_id must not be empty.').isLength({ min: 1 }).trim(),
    body('contract_id', 'book_id must not be empty.').isLength({ min: 1 }).trim(),
    body('tx_addr', 'tx_addr must not be empty.').isLength({ min: 1 }).trim(),
    body('block_number', 'block_number must not be empty.').isLength({ min: 1 }).trim(),

    // Sanitize fields.
    sanitizeBody('*').escape(),
    // Process request after validation and sanitization.
    (req, res, next) => {

        // Extract the validation errors from a request.
        const errors = validationResult(req);
        if (!errors.isEmpty()) {
            // There are errors. Render form again with sanitized values/error messages.
            res.status(400).send({ errors: errors.array() });
            return;
        }

        // Create a Book object with escaped/trimmed data
        var book_fields =
            {
                _id: req.body.book_id, // This is required, or a new ID will be assigned!
                status: 'on_loan'
            };

        // Create a contract object with escaped/trimmed data
        var contract_fields = {
            $push: {
                blk_data: {
                    tx_addr: req.body.tx_addr,
                    block_number: req.body.block_number
                }
            }
        };

        async.parallel({
            //call the function get book model
            book: function(callback) {
                Book.findByIdAndUpdate(req.body.book_id, book_fields, {}).exec(callback);
            },
            contract: function(callback) {
                Contract.findByIdAndUpdate(req.body.contract_id, contract_fields, {}).exec(callback);
            },
        }, function(error, results) {
            if (error) {
                res.status(400).send({ errors: errors.array() });
                return;
            }

            if ((results.book.isNew) || (results.contract.isNew)) {
                res.status(400).send({ errors: errors.array() });
                return;
            }

            var resObj = {
                "res": results.contract.url
            };
            res.status(200).send(JSON.stringify(resObj));
        });
    },
];

Here's my solution using TimeUnit.

UPDATE: I should point out that this is written in groovy, but Java is almost identical.

def remainingStr = ""

/* Days */
int days = MILLISECONDS.toDays(remainingTime) as int
remainingStr += (days == 1) ? '1 Day : ' : "${days} Days : "
remainingTime -= DAYS.toMillis(days)

/* Hours */
int hours = MILLISECONDS.toHours(remainingTime) as int
remainingStr += (hours == 1) ? '1 Hour : ' : "${hours} Hours : "
remainingTime -= HOURS.toMillis(hours)

/* Minutes */
int minutes = MILLISECONDS.toMinutes(remainingTime) as int
remainingStr += (minutes == 1) ? '1 Minute : ' : "${minutes} Minutes : "
remainingTime -= MINUTES.toMillis(minutes)

/* Seconds */
int seconds = MILLISECONDS.toSeconds(remainingTime) as int
remainingStr += (seconds == 1) ? '1 Second' : "${seconds} Seconds"

wrap you shared code into another function:

<script>
  function myFun () {
      //do something
  }

  $(document).ready(function(){
    //Load City by State
    $(document).on('change', '#billing_state_id', function() {
       myFun ();
    });   
    $(document).on('click', '#click_me', function() {
       //do something
       myFun();
    });   
  });
</script>

You might be facing the file permissions issue. Verify your htacces file, did it change from yesterday ? Also, if you were doing any "composer update" or "artisan optimize" stuff, try chowning your laravel project folder for your username.

chown -R yourusername yourlaravelappfolder 

EDIT: the problem is possibly due to your local file permissions concerning Vagrant. Try to

set the permissions to the Vagrantfile containing folder to 777

import org.apache.log4j.PropertyConfigurator;

Import this, then:

Properties props = new Properties();
InputStream is = Main.class.getResourceAsStream("/log4j.properties");

try {
    props.load(is);
} catch (Exception e) {
    // ignore this exception
    log.error("Unable to load log4j properties file.",e);
}
PropertyConfigurator.configure(props);

My java files directory like this:

src/main/java/com/abc/xyz

And log4j directory like this:

src/main/resources

alter table User 
    add constraint userProperties
    foreign key (properties)
    references Properties(ID)

Use mvn dependency:purge-local-repository -DactTransitively=false -Dskip=true if you have maven plugins as one of the modules. Otherwise Maven will try to recompile them, thus downloading the dependencies again.

I think you can go with 3 steps:

git clone
git submodule init
git submodule update

The first declaration has to be an ArrayList, the second can be easily changed to another List type. As such, the second is preferred as it make it clear you don't require a specific implementation. (Sometimes you really do need one implementation, but that is rare)

it's very easy, you just grant the /tmp folder as 777 permission. just type:

chmod -R 777 /tmp

I was trying to run this on a pi zero. Turns out the pi zero has an armv6l architecture so the above won't work for pi zero or pi one. Alternatively here I learned that miniconda doesn't have a recent version of miniconda. Instead I used the same instructions posted here to install berryconda3

Conda is now working. Hope this helps those of you interested in running conda on the pi zero!

In addition to previously provided answers, one option is to follow the 'localhost exception' approach to create the first user if your db is already started with access control (--auth switch). In order to do that, you need to have localhost access to the server and then run:

mongo
use admin
db.createUser(
 {
     user: "user_name",
     pwd: "user_pass",
     roles: [
           { role: "userAdminAnyDatabase", db: "admin" },
           { role: "readWriteAnyDatabase", db: "admin" },
           { role: "dbAdminAnyDatabase", db: "admin" }
        ]
 })

As stated in MongoDB documentation:

The localhost exception allows you to enable access control and then create the first user in the system. With the localhost exception, after you enable access control, connect to the localhost interface and create the first user in the admin database. The first user must have privileges to create other users, such as a user with the userAdmin or userAdminAnyDatabase role. Connections using the localhost exception only have access to create the first user on the admin database.

Here is the link to that section of the docs.

use this

System.Configuration.ConfigurationSettings.AppSettings.Get("Keyname")

Ran into this issue with Parallels and VS 2013. Command + Insert also fixed it in my setup, in addition to the accepted answer. On my Windows USB keyboard Command == WindowsKey.

This is my test. Hope it is useful.

# $COMMAND is the command used to create the reverse ssh tunnel

VB6/VBA uses deterministic approach to destoying objects. Each object stores number of references to itself. When the number reaches zero, the object is destroyed.

Object variables are guaranteed to be cleaned (set to Nothing) when they go out of scope, this decrements the reference counters in their respective objects. No manual action required.

There are only two cases when you want an explicit cleanup:

1. When you want an object to be destroyed before its variable goes out of scope (e.g., your procedure is going to take long time to execute, and the object holds a resource, so you want to destroy the object as soon as possible to release the resource).

2. When you have a circular reference between two or more objects.

   If objectA stores a references to objectB, and objectB stores a reference to objectA, the two objects will never get destroyed unless you brake the chain by explicitly setting objectA.ReferenceToB = Nothing or objectB.ReferenceToA = Nothing.

The code snippet you show is wrong. No manual cleanup is required. It is even harmful to do a manual cleanup, as it gives you a false sense of more correct code.

If you have a variable at a class level, it will be cleaned/destroyed when the class instance is destructed. You can destroy it earlier if you want (see item 1.).

If you have a variable at a module level, it will be cleaned/destroyed when your program exits (or, in case of VBA, when the VBA project is reset). You can destroy it earlier if you want (see item 1.).

Access level of a variable (public vs. private) does not affect its life time.

From the Intel's manual - Instruction Set Reference, the JE and JZ have the same opcode (74 for rel8 / 0F 84 for rel 16/32) also JNE and JNZ (75 for rel8 / 0F 85 for rel 16/32) share opcodes.

JE and JZ they both check for the ZF (or zero flag), although the manual differs slightly in the descriptions of the first JE rel8 and JZ rel8 ZF usage, but basically they are the same.

Here is an extract from the manual's pages 464, 465 and 467.

 Op Code    | mnemonic  | Description
 -----------|-----------|-----------------------------------------------  
 74 cb      | JE rel8   | Jump short if equal (ZF=1).
 74 cb      | JZ rel8   | Jump short if zero (ZF ? 1).

 0F 84 cw   | JE rel16  | Jump near if equal (ZF=1). Not supported in 64-bit mode.
 0F 84 cw   | JZ rel16  | Jump near if 0 (ZF=1). Not supported in 64-bit mode.

 0F 84 cd   | JE rel32  | Jump near if equal (ZF=1).
 0F 84 cd   | JZ rel32  | Jump near if 0 (ZF=1).

 75 cb      | JNE rel8  | Jump short if not equal (ZF=0).
 75 cb      | JNZ rel8  | Jump short if not zero (ZF=0).

 0F 85 cd   | JNE rel32 | Jump near if not equal (ZF=0).
 0F 85 cd   | JNZ rel32 | Jump near if not zero (ZF=0).

At some point in time the object changed from ionic to an uppercase Ionic.

As of July 2017 you need to put Ionic.version into your console to get the version number.

I feel many might be interested in free parameters to alter the shape of the sigmoid function. Second for many applications you want to use a mirrored sigmoid function. Third you might want to do a simple normalization for example the output values are between 0 and 1.

Try:

def normalized_sigmoid_fkt(a, b, x):
   '''
   Returns array of a horizontal mirrored normalized sigmoid function
   output between 0 and 1
   Function parameters a = center; b = width
   '''
   s= 1/(1+np.exp(b*(x-a)))
   return 1*(s-min(s))/(max(s)-min(s)) # normalize function to 0-1

And to draw and compare:

def draw_function_on_2x2_grid(x): 
    fig, ((ax1, ax2), (ax3, ax4)) = plt.subplots(2, 2)
    plt.subplots_adjust(wspace=.5)
    plt.subplots_adjust(hspace=.5)

    ax1.plot(x, normalized_sigmoid_fkt( .5, 18, x))
    ax1.set_title('1')

    ax2.plot(x, normalized_sigmoid_fkt(0.518, 10.549, x))
    ax2.set_title('2')

    ax3.plot(x, normalized_sigmoid_fkt( .7, 11, x))
    ax3.set_title('3')

    ax4.plot(x, normalized_sigmoid_fkt( .2, 14, x))
    ax4.set_title('4')
    plt.suptitle('Different normalized (sigmoid) function',size=10 )

    return fig

Finally:

x = np.linspace(0,1,100)
Travel_function = draw_function_on_2x2_grid(x)

If you don't want it to look horrible I'd suggest defining a list of colours in an array and then using a random number generator to pick one.

If you want a truly random colour you can just generate 3 random numbers from 0 to 255 and then use the Color(int,int,int) constructor to create a new Color instance.

Random randomGenerator = new Random();
int red = randomGenerator.nextInt(256);
int green = randomGenerator.nextInt(256);
int blue = randomGenerator.nextInt(256);

Color randomColour = new Color(red,green,blue);

If you want to make multiple operation use

select (sel1.s1+sel2+s2)

(select sum(hours) s1 from resource) sel1
join 
(select sum(hours) s2 from projects-time)sel2
on sel1.s1=sel2.s2

Have been fighting this all morning and now have it solved and why it happened. Posting with the hope it helps others

I installed the Krypton.Toolkit which added the tools to the Visual studio toolbox automatically. I then added the tools to the designer, which automatically added the dll to the projrect references, however the toolkit was marked as CopyLocal=false

I built an installer, using all dlls in the release build folder (of course the above dll wasn't there).

Setting copylocal=true, then rebuilding the installer, everything worked fine.

Here's some more benchmarks for Docker based memcached server versus host native memcached server using Twemperf benchmark tool https://github.com/twitter/twemperf with 5000 connections and 20k connection rate

Connect time overhead for docker based memcached seems to agree with above whitepaper at roughly twice native speed.

You should also consider that the target has a padding and thus use position instead of offset. You can also account for a potential nav bar you don't want to be overlapping the target.

const $navbar = $('.navbar');

$('a[href^="#"]').on('click', function(e) {
    e.preventDefault();

    const scrollTop =
        $($(this).attr('href')).position().top -
        $navbar.outerHeight();

    $('html, body').animate({ scrollTop });
})

I have found that I can also generate exactly that error output on a perfectly working piece of code by attempting to use the profiler on it.

Note that this was on Windows (where the forking is a bit less elegant).

I was running:

python -m profile -o output.pstats <script> 

And found that removing the profiling removed the error and placing the profiling restored it. Was driving me batty too because I knew the code used to work. I was checking to see if something had updated pool.py... then had a sinking feeling and eliminated the profiling and that was it.

Posting here for the archives in case anybody else runs into it.

Compare two string using equals(-,-) and equalsIgnoreCase(-,-) method of Apache Commons StringUtils class.

StringUtils.equals(-, -) :

StringUtils.equals(null, null)   = true
StringUtils.equals(null, "abc")  = false
StringUtils.equals("abc", null)  = false
StringUtils.equals("abc", "abc") = true
StringUtils.equals("abc", "ABC") = false

StringUtils.equalsIgnoreCase(-, -) :

StringUtils.equalsIgnoreCase(null, null)   = true
StringUtils.equalsIgnoreCase(null, "abc")  = false
StringUtils.equalsIgnoreCase("xyz", null)  = false
StringUtils.equalsIgnoreCase("xyz", "xyz") = true
StringUtils.equalsIgnoreCase("xyz", "XYZ") = true

Now, these methods I tried myself, and I got exactly what was advertised: All the modules.

Alas, really you don't care much about the stdlib, you know what you get with a python install.

Really, I want the stuff that I installed.

What actually, surprisingly, worked just fine was:

pip freeze

Which returned:

Fabric==0.9.3
apache-libcloud==0.4.0
bzr==2.3b4
distribute==0.6.14
docutils==0.7
greenlet==0.3.1
ipython==0.10.1
iterpipes==0.4
libxml2-python==2.6.21

I say "surprisingly" because the package install tool is the exact place one would expect to find this functionality, although not under the name 'freeze' but python packaging is so weird, that I am flabbergasted that this tool makes sense. Pip 0.8.2, Python 2.7.

You can simply set the window state

this.WindowState = System.Windows.Forms.FormWindowState.Maximized;

Another to add to the mix:

EXEC sp_databases

Try overriding the onLongClick listener of the edit text to remove context menu:

EditText myTextField = (EditText)findViewById(R.id.my_edit_text_id);
myTextField.setOnLongClickListener(new OnLongClickListener() {
    @Override
    public boolean onLongClick(View v) {
        return true;
    }
});

Yes the above answers describing the corect way to sort datatable

DataView dv = ft.DefaultView;
dv.Sort = "occr desc";
DataTable sortedDT = dv.ToTable();

But in addition to this, to select particular row in it you can use LINQ and try following

var Temp = MyDataSet.Tables[0].AsEnumerable().Take(1).CopyToDataTable();

According to the jQuery documentation, shorthand CSS properties are not supported.

Depending on what you mean by "total padding", you may be able to do something like this:

var $img = $('img');
var paddT = $img.css('padding-top') + ' ' + $img.css('padding-right') + ' ' + $img.css('padding-bottom') + ' ' + $img.css('padding-left');

In addition to the differences already noted, there's another extremely important difference that I just now discovered the hard way: unlike np.mean, np.average doesn't allow the dtype keyword, which is essential for getting correct results in some cases. I have a very large single-precision array that is accessed from an h5 file. If I take the mean along axes 0 and 1, I get wildly incorrect results unless I specify dtype='float64':

>T.shape
(4096, 4096, 720)
>T.dtype
dtype('<f4')

m1 = np.average(T, axis=(0,1))                #  garbage
m2 = np.mean(T, axis=(0,1))                   #  the same garbage
m3 = np.mean(T, axis=(0,1), dtype='float64')  # correct results

Unfortunately, unless you know what to look for, you can't necessarily tell your results are wrong. I will never use np.average again for this reason but will always use np.mean(.., dtype='float64') on any large array. If I want a weighted average, I'll compute it explicitly using the product of the weight vector and the target array and then either np.sum or np.mean, as appropriate (with appropriate precision as well).

There are many correct answer above. Specifically in Windows, when you don't have ~/.aws/ folder exist and you need to create the new one, it turned out to be another problem, meaning if you just type ".aws" as name, it will error out and will not allow you create the folder with name ".aws".

Here is trick to overcome that, i.e. type in ".aws." meaning dot at the start and dot at the end. Then only windows will accept the name. This has happened with me, so providing an answer here. SO that it may be helpful to others.

Here's a concise method to cut the first X characters using cut(1). This example removes the first 4 characters by cutting a substring starting with 5th character.

echo "$pid" | cut -c 5-

I figured out what it was! When I cleared the fields using the each() method, it also cleared the hidden field which the php needed to run:

if ($_POST['action'] == 'addRunner') 

I used the :not() on the selection to stop it from clearing the hidden field.

If you are using the 'pylab' for interactive plotting you can set the labelsize at creation time with pylab.ylabel('Example', fontsize=40).

If you use pyplot programmatically you can either set the fontsize on creation with ax.set_ylabel('Example', fontsize=40) or afterwards with ax.yaxis.label.set_size(40).

Sounds like you're expecting size_t to be the same as unsigned long (possibly 64 bits) when it's actually an unsigned int (32 bits). Try using %zu in both cases.

I'm not entirely certain though.

import javax.swing.JFrame;
import javax.swing.JOptionPane;

public class ErrorDialog {

  public static void main(String argv[]) {
    String message = "\"The Comedy of Errors\"\n"
        + "is considered by many scholars to be\n"
        + "the first play Shakespeare wrote";
    JOptionPane.showMessageDialog(new JFrame(), message, "Dialog",
        JOptionPane.ERROR_MESSAGE);
  }
}

line=$((${RANDOM} % $(wc -l < /etc/passwd)))
sed -n "${line}p" /etc/passwd

just with your file instead.

In this example I used the file /etc/password, using the special variable ${RANDOM} (about which I learned here), and the sed expression you had, only difference is that I am using double quotes instead of single to allow the variable expansion.

Would something like work?

If you're USING a date then I strongly advise that you use jodatime, http://joda-time.sourceforge.net/. Using System.currentTimeMillis() for fields that are dates sounds like a very bad idea because you'll end up with a lot of useless code.

Both date and calendar are seriously borked, and Calendar is definitely the worst performer of them all.

I'd advise you to use System.currentTimeMillis() when you are actually operating with milliseconds, for instance like this

 long start = System.currentTimeMillis();
    .... do something ...
 long elapsed = System.currentTimeMillis() -start;

Yes, the first one is a static method also called class method, while the second one is an instance method.

Consider the following examples, to understand it in more detail.

In ES5

function Person(firstName, lastName) {
   this.firstName = firstName;
   this.lastName = lastName;
}

Person.isPerson = function(obj) {
   return obj.constructor === Person;
}

Person.prototype.sayHi = function() {
   return "Hi " + this.firstName;
}

In the above code, isPerson is a static method, while sayHi is an instance method of Person.

Below, is how to create an object from Person constructor.

var aminu = new Person("Aminu", "Abubakar");

Using the static method isPerson.

Person.isPerson(aminu); // will return true

Using the instance method sayHi.

aminu.sayHi(); // will return "Hi Aminu"

In ES6

class Person {
   constructor(firstName, lastName) {
      this.firstName = firstName;
      this.lastName = lastName;
   }

   static isPerson(obj) {
      return obj.constructor === Person;
   }

   sayHi() {
      return `Hi ${this.firstName}`;
   }
}

Look at how static keyword was used to declare the static method isPerson.

To create an object of Person class.

const aminu = new Person("Aminu", "Abubakar");

Using the static method isPerson.

Person.isPerson(aminu); // will return true

Using the instance method sayHi.

aminu.sayHi(); // will return "Hi Aminu"

NOTE: Both examples are essentially the same, JavaScript remains a classless language. The class introduced in ES6 is primarily a syntactical sugar over the existing prototype-based inheritance model.

Just right click on a table and select "backup". The popup will show various options, including "Format", select "plain" and you get plain SQL.

pgAdmin is just using pg_dump to create the dump, also when you want plain SQL.

It uses something like this:

pg_dump --user user --password --format=plain --table=tablename --inserts --attribute-inserts etc.

Not necessarily in all cases.

I m using Jboss 7.0.8 and Eclipselink 2.7.0. In my case to load entities without adding the same in persistence.xml, I added the following system property in Jboss Standalone XML:

<property name="eclipselink.archive.factory" value="org.jipijapa.eclipselink.JBossArchiveFactoryImpl"/>

If using JavaScript then:

$('#myModal').modal({
    backdrop: 'static',
    keyboard: false
})

or in HTML:

<a data-controls-modal="your_div_id" data-backdrop="static" data-keyboard="false" href="#">

Here is what works for me on Swift 3

let _ = (dict[key].map { $0 as? String } ?? "")

Note - if you want to pass a data attribute to a React Component, you need to handle them a little differently than other props.

2 options

Don't use camel case

<Option data-img-src='value' ... />

And then in the component, because of the dashes, you need to refer to the prop in quotes.

// @flow
class Option extends React.Component {

  props: {
    'data-img-src': string
  }

And when you refer to it later, you don't use the dot syntax

  render () {
    return (
      <option data-img-src={this.props['data-img-src']} >...</option>
    )
  }
}

Or use camel case

<Option dataImgSrc='value' ... />

And then in the component, you need to convert.

// @flow
class Option extends React.Component {

  props: {
    dataImgSrc: string
  }

And when you refer to it later, you don't use the dot syntax

  render () {
    return (
      <option data-img-src={this.props.dataImgSrc} >...</option>
    )
  }
}

Mainly just realize data- attributes and aria- attributes are treated specially. You are allowed to use hyphens in the attribute name in those two cases.

I faced the same error and did some research to only see that there could be different scenarios to this error. Let me share my findings.

Scenario 1: There cannot be spaces beside the = (equals) sign

$ export TEMP_ENV = example-value
-bash: export: `=': not a valid identifier
// this is the answer to the question

$ export TEMP_ENV =example-value
-bash: export: `=example-value': not a valid identifier

$ export TEMP_ENV= example-value
-bash: export: `example-value': not a valid identifier

Scenario 2: Object value assignment should not have spaces besides quotes

$ export TEMP_ENV={ "key" : "json example" } 
-bash: export: `:': not a valid identifier
-bash: export: `json example': not a valid identifier
-bash: export: `}': not a valid identifier

Scenario 3: List value assignment should not have spaces between values

$ export TEMP_ENV=[1,2 ,3 ]
-bash: export: `,3': not a valid identifier
-bash: export: `]': not a valid identifier

I'm sharing these, because I was stuck for a couple of hours trying to figure out a workaround. Hopefully, it will help someone in need.

Using @yogihosting answer when she used the Microsoft built-in LinkedList and LinkedListNode to answer the question, you can achieve the same results:

using System;
using System.Collections.Generic;
using Codebase;

namespace Cmd
{
    static class Program
    {
        static void Main(string[] args)
        {
            var tune = new LinkedList(); //Using custom code instead of the built-in LinkedList<T>
            tune.AddFirst("do"); // do
            tune.AddLast("so"); // do - so
            tune.AddAfter(tune.First, "re"); // do - re- so
            tune.AddAfter(tune.First.Next, "mi"); // do - re - mi- so
            tune.AddBefore(tune.Last, "fa"); // do - re - mi - fa- so
            tune.RemoveFirst(); // re - mi - fa - so
            tune.RemoveLast(); // re - mi - fa
            Node miNode = tune.Find("mi"); //Using custom code instead of the built in LinkedListNode
            tune.Remove(miNode); // re - fa
            tune.AddFirst(miNode); // mi- re - fa
 }
}

There are multiple ways you can remove/filter the null values from a column in DataFrame.

Lets create a simple DataFrame with below code:

date = ['2016-03-27','2016-03-28','2016-03-29', None, '2016-03-30','2016-03-31']
df = spark.createDataFrame(date, StringType())

Now you can try one of the below approach to filter out the null values.

# Approach - 1
df.filter("value is not null").show()

# Approach - 2
df.filter(col("value").isNotNull()).show()

# Approach - 3
df.filter(df["value"].isNotNull()).show()

# Approach - 4
df.filter(df.value.isNotNull()).show()

# Approach - 5
df.na.drop(subset=["value"]).show()

# Approach - 6
df.dropna(subset=["value"]).show()

# Note: You can also use where function instead of a filter.

You can also check the section "Working with NULL Values" on my blog for more information.

I hope it helps.

Basically, the third parameter in loggedIn should not be an integer, it should be an object of some kind, but we can't know for sure because you did not name the parameters in the method call. Provide the method signature so we can see for sure. Perhaps it takes an NSNumber or something.

Arrays have an implicit member variable holding the length:

for(int i=0; i<myArray.length; i++) {
    System.out.println(myArray[i]);
}

Alternatively if using >=java5, use a for each loop:

for(Object o : myArray) {
    System.out.println(o);
}

Setting the underlying socket ReceiveTimeout property did the trick. You can access it like this: yourTcpClient.Client.ReceiveTimeout. You can read the docs for more information.

Now the code will only "sleep" as long as needed for some data to arrive in the socket, or it will raise an exception if no data arrives, at the beginning of a read operation, for more than 20ms. I can tweak this timeout if needed. Now I'm not paying the 20ms price in every iteration, I'm only paying it at the last read operation. Since I have the content-length of the message in the first bytes read from the server I can use it to tweak it even more and not try to read if all expected data has been already received.

I find using ReceiveTimeout much easier than implementing asynchronous read... Here is the working code:

string SendCmd(string cmd, string ip, int port)
{
  var client = new TcpClient(ip, port);
  var data = Encoding.GetEncoding(1252).GetBytes(cmd);
  var stm = client.GetStream();
  stm.Write(data, 0, data.Length);
  byte[] resp = new byte[2048];
  var memStream = new MemoryStream();
  var bytes = 0;
  client.Client.ReceiveTimeout = 20;
  do
  {
      try
      {
          bytes = stm.Read(resp, 0, resp.Length);
          memStream.Write(resp, 0, bytes);
      }
      catch (IOException ex)
      {
          // if the ReceiveTimeout is reached an IOException will be raised...
          // with an InnerException of type SocketException and ErrorCode 10060
          var socketExept = ex.InnerException as SocketException;
          if (socketExept == null || socketExept.ErrorCode != 10060)
              // if it's not the "expected" exception, let's not hide the error
              throw ex;
          // if it is the receive timeout, then reading ended
          bytes = 0;
      }
  } while (bytes > 0);
  return Encoding.GetEncoding(1252).GetString(memStream.ToArray());
}

For Swift 3.0 NSBundle doesn't work, Following code works perfectly.

let versionNumberString =
      Bundle.main.object(forInfoDictionaryKey: "CFBundleShortVersionString")
          as! String

and for just the build number, it is:

let buildNumberString =
      Bundle.main.object(forInfoDictionaryKey: "CFBundleVersion")
          as! String

Confusingly 'CFBundleVersion' is the build number as entered in Xcode on General->Identity.

You will need to change JAVA_HOME path to the Java SDK directory instead of the Java RE directory. In Windows you can do this using the set command in a command prompt.

e.g.

set JAVA_HOME="C:\Program Files\Java\jdk1.6.0_14"

If self could be nil in the closure use [weak self].

If self will never be nil in the closure use [unowned self].

The Apple Swift documentation has a great section with images explaining the difference between using strong, weak, and unowned in closures:

https://developer.apple.com/library/content/documentation/Swift/Conceptual/Swift_Programming_Language/AutomaticReferenceCounting.html

Git won't reset files that aren't on repository. So, you can:

$ git add .
$ git reset --hard

This will stage all changes, which will cause Git to be aware of those files, and then reset them.

If this does not work, you can try to stash and drop your changes:

$ git stash
$ git stash drop

What worked for me was to create a new repository and rename the image with

$ docker tag image_id myname/server:latest

To complement loyola's answer it is worth mentioning that as of MySQL 5.1 log_slow_queries is deprecated and is replaced with slow-query-log

Using log_slow_queries will cause your service mysql restart or service mysql start to fail

If there is a Content-Disposition: attachment reponse header, Firefox will ask you to save the file, even if you have JSONView installed to format JSON.

To bypass this problem, I removed the header ("Content-Disposition" : null) with moz-rewrite Firefox addon that allows you to modify request and response headers https://addons.mozilla.org/en-US/firefox/addon/moz-rewrite-js/

An example of JSON file served with this header is the Twitter API (it looks like they added it recently). If you want to try this JSON file, I have a script to access Twitter API in browser: https://gist.github.com/baptx/ffb268758cd4731784e3

Match objects are always true, and None is returned if there is no match. Just test for trueness.

if re.match(...):

After failed attempts on the basis of all given solutions. I replace \n with some special word and then split. For me following did the trick:

article = "Alice phoned\n bob.";
article = article.replace("\\n", " NEWLINE ");
String sen [] = article.split(" NEWLINE ");

I couldn't replicate the example given in the question. But, I guess this logic can be applied.

ws2s project is aimed at bring socket to browser-side js. It is a websocket server which transform websocket to socket.

ws2s schematic diagram

code sample:

var socket = new WS2S("wss://ws2s.feling.io/").newSocket()

socket.onReady = () => {
  socket.connect("feling.io", 80)
  socket.send("GET / HTTP/1.1\r\nHost: feling.io\r\nConnection: close\r\n\r\n")
}

socket.onRecv = (data) => {
  console.log('onRecv', data)
}

Use str.join:

>>> tup = ('a', 'b', 'c', 'd', 'g', 'x', 'r', 'e')
>>> ''.join(tup)
'abcdgxre'
>>>
>>> help(str.join)
Help on method_descriptor:

join(...)
    S.join(iterable) -> str

    Return a string which is the concatenation of the strings in the
    iterable.  The separator between elements is S.

>>>

Much easier aproach. Consider a task:

provision:
        ansible-playbook -vvvv \
        -i .vagrant/provisioners/ansible/inventory/vagrant_ansible_inventory \
        --private-key=.vagrant/machines/default/virtualbox/private_key \
        --start-at-task="$(AT)" \
        -u vagrant playbook.yml

Now when I want to call it I just run something like:

AT="build assets" make provision

or just:

make provision in this case AT is an empty string

I had the same question but applying the provided solutions changed the file to write in. Once I selected the new excel file, I was also writing in that file and not in my original file. My solution for this issue is below:

Sub GetData()

    Dim excelapp As Application
    Dim source As Workbook
    Dim srcSH1 As Worksheet
    Dim sh As Worksheet
    Dim path As String
    Dim nmr As Long
    Dim i As Long

    nmr = 20

    Set excelapp = New Application

    With Application.FileDialog(msoFileDialogOpen)
        .AllowMultiSelect = False
        .Filters.Add "Excel Files", "*.xlsx; *.xlsm; *.xls; *.xlsb", 1
        .Show
        path = .SelectedItems.Item(1)
    End With

    Set source = excelapp.Workbooks.Open(path)
    Set srcSH1 = source.Worksheets("Sheet1")
    Set sh = Sheets("Sheet1")

    For i = 1 To nmr
        sh.Cells(i, "A").Value = srcSH1.Cells(i, "A").Value
    Next i

End Sub

With excelapp a new application will be called. The with block sets the path for the external file. Finally, I set the external Workbook with source and srcSH1 as a Worksheet within the external sheet.

You can use this function

public void delete()    
{   
    File f = new File("E://implementation1/");
    File[] files = f.listFiles();
    for (File file : files) {
        file.delete();
    }
}

@PrePersist
void preInsert() {
    if (this.dateOfConsent == null)
        this.dateOfConsent = LocalDateTime.now();
    if(this.consentExpiry==null)
        this.consentExpiry = this.dateOfConsent.plusMonths(3);
}

In my case due to the field being LocalDateTime i used this, it is recommended due to vendor independence

Worth knowing:

If you are running an ENTRYPOINT script ... the script will work with the shebang

#!/bin/bash -x

But will stop the container from stopping with

#!/bin/bash -xe

Executing programs through the shell means that all user input passed to the program is interpreted according to the syntax and semantic rules of the invoked shell. At best, this only causes inconvenience to the user, because the user has to obey these rules. For instance, paths containing special shell characters like quotation marks or blanks must be escaped. At worst, it causes security leaks, because the user can execute arbitrary programs.

shell=True is sometimes convenient to make use of specific shell features like word splitting or parameter expansion. However, if such a feature is required, make use of other modules are given to you (e.g. os.path.expandvars() for parameter expansion or shlex for word splitting). This means more work, but avoids other problems.

In short: Avoid shell=True by all means.

Just to add to the correct answer above, in Vue.JS v1.0 you can write

<a v-on:click="doSomething">

So in this example it would be

 v-on:change="foo"

See: http://v1.vuejs.org/guide/syntax.html#Arguments

The code is fine just setStyle of paint as STROKE

paint.setStyle(Paint.Style.STROKE);

The error is a result of the missing semicolon on the third line:

window.Glog = function(msg) {
  console.log(msg);
}; // <--- Add this semicolon

(function(win) {
  // ...
})(window);

The ECMAScript specification has specific rules for automatic semicolon insertion, however in this case a semicolon isn't automatically inserted because the parenthesised expression that begins on the next line can be interpreted as an argument list for a function call.

This means that without that semicolon, the anonymous window.Glog function was being invoked with a function as the msg parameter, followed by (window) which was subsequently attempting to invoke whatever was returned.

This is how the code was being interpreted:

window.Glog = function(msg) {
  console.log(msg);
}(function(win) {
  // ...
})(window);

children() only looks at the immediate children of the node, while find() traverses the entire DOM below the node, so children() should be faster given equivalent implementations. However, find() uses native browser methods, while children() uses JavaScript interpreted in the browser. In my experiments there isn't much performance difference in typical cases.

Which to use depends on whether you only want to consider the immediate descendants or all nodes below this one in the DOM, i.e., choose the appropriate method based on the results you desire, not the speed of the method. If performance is truly an issue, then experiment to find the best solution and use that (or see some of the benchmarks in the other answers here).

In my experience most developers naturally migrate towards white box testing. Since we need to ensure that the underlying algorithm is "correct", we tend to focus more on the internals. But, as has been pointed out, both white and black box testing is important.

Therefore, I prefer to have testers focus more on the Black Box tests, to cover for the fact that most developers don't really do it, and frequently aren't very good at it.

That isn't to say that testers should be kept in the dark about how the system works, just that I prefer them to focus more on the problem domain and how actual users interact with the system, not whether the function SomeMethod(int x) will correctly throw an exception if x is equal to 5.

Works the same way as things above. If you need seconds don't forget to / 1000

The Miro video converter does a beautiful job and is drag-n-drop. http://www.mirovideoconverter.com/

BTW it's FREE and also very good for mobile device encoding.

    function round(num,dec)
    {
      num = Math.round(num+'e'+dec)
      return Number(num+'e-'+dec)
    }
      //Round to a decimal of your choosing:
    round(1.3453,2)

If you're looking to change the title text size and the text color you have to change the NSDictionary titleTextAttributes, for 2 of its objects:

    self.navigationController.navigationBar.titleTextAttributes = [NSDictionary dictionaryWithObjectsAndKeys:[UIFont fontWithName:@"Arial" size:13.0],NSFontAttributeName,
                                                                  [UIColor whiteColor], NSForegroundColorAttributeName, 
                                                                  nil];

adding private static Scanner in; does not really fix the problem, it only clears out the warning. Making the scanner static means it remains open forever (or until the class get's unloaded, which nearly is "forever"). The compiler gives you no warning any more, since you told him "keep it open forever". But that is not what you really wanted to, since you should close resources as soon as you don't need them any more.

HTH, Manfred.

The definition of SIZE_T is found at: https://msdn.microsoft.com/en-us/library/cc441980.aspx and https://msdn.microsoft.com/en-us/library/cc230394.aspx

Pasting here the required information:

SIZE_T is a ULONG_PTR representing the maximum number of bytes to which a pointer can point.

This type is declared as follows:

typedef ULONG_PTR SIZE_T;

A ULONG_PTR is an unsigned long type used for pointer precision. It is used when casting a pointer to a long type to perform pointer arithmetic.

This type is declared as follows:

typedef unsigned __int3264 ULONG_PTR;

Well, string type is a completely managed class for character strings, while char[] is still what it was in C, a byte array representing a character string for you.

In terms of API and standard library everything is implemented in terms of strings and not char[], but there are still lots of functions from the libc that receive char[] so you may need to use it for those, apart from that I would always use std::string.

In terms of efficiency of course a raw buffer of unmanaged memory will almost always be faster for lots of things, but take in account comparing strings for example, std::string has always the size to check it first, while with char[] you need to compare character by character.

You are using POST method, but are you providing an array of data? E.g.

curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);

Sorting by C and D needs to be put into number form for the corresponding column, ie 3 and 4, respectively. Eg Order By 2 asc")

for the linq expression you can use like this :

 List<int> list = new List<int>() {1,2,3 };
        var result = (from l in list
                     select l).FirstOrDefault();

for the lambda expression you can use like this

List list = new List() { 1, 2, 3 }; int x = list.FirstOrDefault();

An alternative approach may be to embed images in the email using the cid method. (Basically including the image as an attachment, and then embedding it). In my experience, this approach seems to be well supported these days.

Object Oriented

This is the recommended way.

$datetime = new DateTime('2010-12-30 23:21:46');

echo $datetime->format(DateTime::ATOM); // Updated ISO8601

Procedural

For older versions of PHP, or if you are more comfortable with procedural code.

echo date(DATE_ISO8601, strtotime('2010-12-30 23:21:46'));

Don't forget to define permission in your AndroidManifest.xml

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

You can delete item through id

<button @click="deleteEvent(event.id)">Delete</button>

Inside your JS code

deleteEvent(id){
  this.events = this.events.filter((e)=>e.id !== id )
}

Vue wraps an observed array’s mutation methods so they will also trigger view updates. Click here for more details.

You might think this will cause Vue to throw away the existing DOM and re-render the entire list - luckily, that is not the case.

This will work even if the url ends with a /:

var segments = window.location.pathname.split('/');
var toDelete = [];
for (var i = 0; i < segments.length; i++) {
    if (segments[i].length < 1) {
        toDelete.push(i);
    }
}
for (var i = 0; i < toDelete.length; i++) {
    segments.splice(i, 1);
}
var filename = segments[segments.length - 1];
console.log(filename);

You urls are not in the same repository, so you can't do it with the svn diff command.

svn: 'http://svn.boost.org/svn/boost/sandbox/boost/extension' isn't in the same repository as 'http://cloudobserver.googlecode.com/svn'

Another way you could do it, is export each repos using svn export, and then use the diff command to compare the 2 directories you exported.

// Export repositories
svn export http://svn.boost.org/svn/boost/sandbox/boost/extension/ repos1
svn export http://cloudobserver.googlecode.com/svn/branches/v0.4/Boost.Extension.Tutorial/libs/boost/extension/ repos2

// Compare exported directories
diff repos1 repos2 > file.diff

I know this question is 4 years old, but I have a couple different options:

Option 1: Using tar --to-command grep

The following line will look in example.tgz for PATTERN. This is similar to @Jester's example, but I couldn't get his pattern matching to work.

tar xzf example.tgz --to-command 'grep --label="$TAR_FILENAME" -H PATTERN ; true'

Option 2: Using tar -tzf

The second option is using tar -tzf to list the files, then go through them with grep. You can create a function to use it over and over:

targrep () {
    for i in $(tar -tzf "$1"); do
        results=$(tar -Oxzf "$1" "$i" | grep --label="$i" -H "$2")
        echo "$results"
    done
}

Usage:

targrep example.tar.gz "pattern"

In case of Mac OSX,

Go to Targets -> Build Phases click + to Copy new files build phases Select product directory and drop the file there.

Clean and run the project.

I did it like this:

var listOfRows = new List<DataRow>();
foreach (var row in resultTable.Rows.Cast<DataRow>())
{
    var isEmpty = row.ItemArray.All(x => x == null || (x!= null && string.IsNullOrWhiteSpace(x.ToString())));
    if (!isEmpty)
    {
        listOfRows.Add(row);
    }
}

Create the animation

- (CABasicAnimation *)spinAnimationWithDuration:(CGFloat)duration clockwise:(BOOL)clockwise repeat:(BOOL)repeats
{
    CABasicAnimation *anim = [CABasicAnimation animationWithKeyPath:@"transform.rotation.z"];
    anim.toValue = clockwise ? @(M_PI * 2.0) : @(M_PI * -2.0);
    anim.duration = duration;
    anim.cumulative = YES;
    anim.repeatCount = repeats ? CGFLOAT_MAX : 0;
    return anim;
}

Add it to a view like this

CABasicAnimation *animation = [self spinAnimationWithDuration:1.0 clockwise:YES repeat:YES];
[self.spinningView.layer addAnimation:animation forKey:@"rotationAnimation"];

How is this answer different? You will have way cleaner code if most of your functions returns objects instead of just manipulating some objects here and there.

The following code works for me on owl carousel .

https://github.com/OwlFonk/OwlCarousel

$(".owl-carousel").owlCarousel({
    items: 1,
    autoplay: true,
    navigation: true,
    navigationText: ["<i class='fa fa-angle-left'></i>", "<i class='fa fa-angle-right'></i>"]
});

For OwlCarousel2

https://owlcarousel2.github.io/OwlCarousel2/docs/api-options.html

 $(".owl-carousel").owlCarousel({
    items: 1,
    autoplay: true,
    nav: true,
    navText: ["<i class='fa fa-angle-left'></i>", "<i class='fa fa-angle-right'></i>"]
});

How are you generating your data?

See how the output shows that your data is of 'object' type? the groupby operations specifically check whether each column is a numeric dtype first.

In [31]: data
Out[31]: 
<class 'pandas.core.frame.DataFrame'>
DatetimeIndex: 2557 entries, 2004-01-01 00:00:00 to 2010-12-31 00:00:00
Freq: <1 DateOffset>
Columns: 360 entries, -89.75 to 89.75
dtypes: object(360)

look ?

Did you initialize an empty DataFrame first and then filled it? If so that's probably why it changed with the new version as before 0.9 empty DataFrames were initialized to float type but now they are of object type. If so you can change the initialization to DataFrame(dtype=float).

You can also call frame.astype(float)

If you are here for a filepath just use "\\"

import os
path = r"c:\file"+"\\"+"path"
os.path.normpath(path)

which will outputc:\file\path

You can LEFT JOIN the two tables. If there is no corresponding row in the second table, the values will be NULL.

SELECT id FROM partmaster LEFT JOIN product_details ON (...) WHERE product_details.part_num IS NULL

No, a comma-separated list is what you want in this case.

I would assume so, I have Python 2.4, 2.5 and 2.6 installed side-by-side on the same computer.

Another alternative, which is also quite popular is the Java Service Wrapper. This is also quite popular around the OSS community.

An XSD is included with EntLib 5, and is installed in the Visual Studio schema directory. In my case, it could be found at:

"C:\Program Files (x86)\Microsoft Visual Studio 10.0\Xml\Schemas\EnterpriseLibrary.Configuration.xsd"

CONTEXT

• Visual Studio 2010
• Enterprise Library 5

STEPS TO REMOVE THE WARNINGS

1. open app.config in your Visual Studio project
2. right click in the XML Document editor, select "Properties"
3. add the fully qualified path to the "EnterpriseLibrary.Configuration.xsd"

ASIDE

It is worth repeating that these "Error List" "Messages" ("Could not find schema information for the element") are only visible when you open the app.config file. If you "Close All Documents" and compile... no messages will be reported.

By design the body content in ASP.NET Web API is treated as forward-only stream that can be read only once.

The first read in your case is being done when Web API is binding your model, after that the Request.Content will not return anything.

You can remove the contact from your action parameters, get the content and deserialize it manually into object (for example with Json.NET):

[HttpPut]
public HttpResponseMessage Put(int accountId)
{
    HttpContent requestContent = Request.Content;
    string jsonContent = requestContent.ReadAsStringAsync().Result;
    CONTACT contact = JsonConvert.DeserializeObject<CONTACT>(jsonContent);
    ...
}

That should do the trick (assuming that accountId is URL parameter so it will not be treated as content read).

you cannot set this in javascript, you have to do this with html/css:

<style type="text/css" media="print">
  @page { size: landscape; }
</style>

EDIT: See this Question and the accepted answer for more information on browser support: Is @Page { size:landscape} obsolete?

You may find the following function useful:

function typeOf(obj) {
  return {}.toString.call(obj).split(' ')[1].slice(0, -1).toLowerCase();
}

Or in ES7 (comment if further improvements)

const { toString } = Object.prototype;

function typeOf(obj) {
  const stringified = obj::toString();
  const type = stringified.split(' ')[1].slice(0, -1);
      
  return type.toLowerCase();
}

Results:

typeOf(); //undefined
typeOf(null); //null
typeOf(NaN); //number
typeOf(5); //number
typeOf({}); //object
typeOf([]); //array
typeOf(''); //string
typeOf(function () {}); //function
typeOf(/a/) //regexp
typeOf(new Date()) //date
typeOf(new Error) //error
typeOf(Promise.resolve()) //promise
typeOf(function *() {}) //generatorfunction
typeOf(new WeakMap()) //weakmap
typeOf(new Map()) //map
typeOf(async function() {}) //asyncfunction

Thanks @johnrees for notifying me of: error, promise, generatorfunction

Refer to following links:

1. http://developer.android.com/reference/android/os/AsyncTask.html
2. http://labs.makemachine.net/2010/05/android-asynctask-example/

You cannot pass more than three arguments, if you want to pass only 1 argument then use void for the other two arguments.

1. private class DownloadFilesTask extends AsyncTask<URL, Integer, Long> 


2. protected class InitTask extends AsyncTask<Context, Integer, Integer>

An asynchronous task is defined by a computation that runs on a background thread and whose result is published on the UI thread. An asynchronous task is defined by 3 generic types, called Params, Progress and Result, and 4 steps, called onPreExecute, doInBackground, onProgressUpdate and onPostExecute.

I have used a Wrapper to get around this problem. Create a wrapper object and pass your mocked method.

See Mocking Static Methods for Unit Testing by Paul Irwin, it has nice examples.

There are few mistakes you are doing:

1. You need to add proper object in the array in addRow method
2. You can use splice method to remove an element from an array at particular index.
3. You need to pass the current row as prop to my-item component, where this can be modified.

You can see working code here.

addRow(){
   this.rows.push({description: '', unitprice: '' , code: ''}); // what to push unto the rows array?
},
removeRow(index){
   this. itemList.splice(index, 1)
}

For me just $('[data-toggle="modal"]').click(function(){}); is working fine.

My answer builds on top of the widely-accepted answer from joaomgcd. If the user has Facebook installed but disabled (for example by using App Quarantine), this method will not work. The intent for the Twitter app will be selected but it will not be able to process it as it is disabled.

Instead of:

context.getPackageManager().getPackageInfo("com.facebook.katana", 0);
return new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/620681997952698"));

You can use the following to decide what to do:

PackageInfo info = context.getPackageManager().getPackageInfo("com.facebook.katana", 0);
if(info.applicationInfo.enabled)
    return new Intent(Intent.ACTION_VIEW, Uri.parse("fb://profile/620681997952698"));
else
    return new Intent(Intent.ACTION_VIEW, Uri.parse("https://www.facebook.com/620681997952698"));

I had a similar issue, but with no source code to run on Xcode.

So if you want to test an application on a real device with a fake location you should use a VPN application.

There are plenty in the App Store to choose from - free ones without the option to choose a specific country/city and free ones which assign you a random location or asks you to choose from a limited set of default options.

Using array variables

set $(ps | egrep "^11383 "); echo $4

or

A=( $(ps | egrep "^11383 ") ) ; echo ${A[3]}

Here is one approach you can use which would work even if both dictonaries don't have same keys:

d1 = {'a':'test','b':'btest','d':'dreg'}
d2 = {'a':'cool','b':'main','c':'clear'}

d = {}

for key in set(d1.keys() + d2.keys()):
    try:
        d.setdefault(key,[]).append(d1[key])        
    except KeyError:
        pass

    try:
        d.setdefault(key,[]).append(d2[key])          
    except KeyError:
        pass

print d

This would generate below input:

{'a': ['test', 'cool'], 'c': ['clear'], 'b': ['btest', 'main'], 'd': ['dreg']}

request.getSession() will return a current session. if current session does not exist, then it will create a new one.

request.getSession(true) will return current session. If current session does not exist, then it will create a new session.

So basically there is not difference between both method.

request.getSession(false) will return current session if current session exists. If not, it will not create a new session.

I hope the below mentioned code will answer your question.

def root(x,a):
    y = 1 / a
    y = float(y)
    print y
    z = x ** y
    print z

base = input("Please input the base value:")
power = float(input("Please input the root value:"))


root(base,power) 

C# 8.0 is published now so you can make reference types nullable too. For this you have to add

#nullable enable

Feature over your namespace. It is detailed here

For example something like this will work:

#nullable enable
namespace TestCSharpEight
{
  public class Developer
  {
    public string FullName { get; set; }
    public string UserName { get; set; }

    public Developer(string fullName)
    {
        FullName = fullName;
        UserName = null;
    }
}}

Also you can have a look this nice article from John Skeet that explains details.

Use the getResourceAsStream() method on the ServletContext object, e.g.

servletContext.getResourceAsStream("/WEB-INF/myfile");

How you get a reference to the ServletContext depends on your application... do you want to do it from a Servlet or from a JSP?

EDITED: If you're inside a Servlet object, then call getServletContext(). If you're in JSP, use the predefined variable application.

IF NOT EXISTS (SELECT 1  FROM SYS.COLUMNS WHERE  
OBJECT_ID = OBJECT_ID(N'[dbo].[Person]') AND name = 'DateOfBirth')
BEGIN
ALTER TABLE [dbo].[Person] ADD DateOfBirth DATETIME
END

Just for curiosity and to compare with Saint Hill's answer.

If you need to process heavy data you should not use JVM in client mode. Client mode is not made for optimizations.

Let's compare results of @Saint Hill benchmarks using a JVM in Client mode and Server mode.

Core2Quad Q6600 G0 @ 2.4GHz
JavaSE 1.7.0_40

CONCLUSION:

As you can see, server mode is much faster.

Be explicit - then the compiler won't warn that you perhaps made a mistake.

while ( (list = list->next) != NULL )

or

while ( (list = list->next) )

Some day you'll be glad the compiler told you, people do make that mistake ;)

There is no easy, out of the box solution against XSS. The OWASP ESAPI API has some support for the escaping that is very usefull, and they have tag libraries.

My approach was to basically to extend the stuts 2 tags in following ways.

1. Modify s:property tag so it can take extra attributes stating what sort of escaping is required (escapeHtmlAttribute="true" etc.). This involves creating a new Property and PropertyTag classes. The Property class uses OWASP ESAPI api for the escaping.
2. Change freemarker templates to use the new version of s:property and set the escaping.

If you didn't want to modify the classes in step 1, another approach would be to import the ESAPI tags into the freemarker templates and escape as needed. Then if you need to use a s:property tag in your JSP, wrap it with and ESAPI tag.

I have written a more detailed explanation here.

http://www.nutshellsoftware.org/software/securing-struts-2-using-esapi-part-1-securing-outputs/

I agree escaping inputs is not ideal.

you can use native javascript like this

<script>_x000D_
function myFunction() {_x000D_
  var input, filter, table, tr, td, i;_x000D_
  input = document.getElementById("myInput");_x000D_
  filter = input.value.toUpperCase();_x000D_
  table = document.getElementById("myTable");_x000D_
  tr = table.getElementsByTagName("tr");_x000D_
  for (i = 0; i < tr.length; i++) {_x000D_
    td = tr[i].getElementsByTagName("td")[0];_x000D_
    if (td) {_x000D_
      if (td.innerHTML.toUpperCase().indexOf(filter) > -1) {_x000D_
        tr[i].style.display = "";_x000D_
      } else {_x000D_
        tr[i].style.display = "none";_x000D_
      }_x000D_
    }       _x000D_
  }_x000D_
}_x000D_
</script>

import platform
is_windows = any(platform.win32_ver())

or

import sys
is_windows = hasattr(sys, 'getwindowsversion')

If you have more than one network adapter and more than one adapter is active (f.e WLAN + VPN) you need a bit more complex check. You can use this one-liner:

[System.Net.DNS]::GetHostByAddress(([System.Net.DNS]::GetHostAddresses([System.Environment]::MachineName) | Where-Object { $_.AddressFamily -eq "InterNetwork" } | Select-Object IPAddressToString)[0].IPAddressToString).HostName.ToLower()

I've created a variant of https://stackoverflow.com/a/17845473/189411

where you can set min and max text size in relation of min and max size of box that you want "check" size. In addition you can check size of dom element different than box where you want apply text size.

You resize text between 19px and 25px on #size-2 element, based on 500px and 960px width of #size-2 element

resizeTextInRange(500,960,19,25,'#size-2');

You resize text between 13px and 20px on #size-1 element, based on 500px and 960px width of body element

resizeTextInRange(500,960,13,20,'#size-1','body');

complete code are there https://github.com/kiuz/sandbox-html-js-css/tree/gh-pages/text-resize-in-range-of-text-and-screen/src

function inRange (x,min,max) {
    return Math.min(Math.max(x, min), max);
}

function resizeTextInRange(minW,maxW,textMinS,textMaxS, elementApply, elementCheck=0) {

    if(elementCheck==0){elementCheck=elementApply;}

    var ww = $(elementCheck).width();
    var difW = maxW-minW;
    var difT = textMaxS- textMinS;
    var rapW = (ww-minW);
    var out=(difT/100)*(rapW/(difW/100))+textMinS;
    var normalizedOut = inRange(out, textMinS, textMaxS);
    $(elementApply).css('font-size',normalizedOut+'px');

    console.log(normalizedOut);

}

$(function () {
    resizeTextInRange(500,960,19,25,'#size-2');
    resizeTextInRange(500,960,13,20,'#size-1','body');
    $(window).resize(function () {
        resizeTextInRange(500,960,19,25,'#size-2');
        resizeTextInRange(500,960,13,20,'#size-1','body');
    });
});

It points to your top level output directory (which by default is target):

https://web.archive.org/web/20150527103929/http://docs.codehaus.org/display/MAVENUSER/MavenPropertiesGuide

EDIT: As has been pointed out, Codehaus is now sadly defunct. You can find details about these properties from Sonatype here:

http://books.sonatype.com/mvnref-book/reference/resource-filtering-sect-properties.html#resource-filtering-sect-project-properties

If you are ever trying to reference output directories in Maven, you should never use a literal value like target/classes. Instead you should use property references to refer to these directories.

    project.build.sourceDirectory
    project.build.scriptSourceDirectory
    project.build.testSourceDirectory
    project.build.outputDirectory
    project.build.testOutputDirectory
    project.build.directory

sourceDirectory, scriptSourceDirectory, and testSourceDirectory provide access to the source directories for the project. outputDirectory and testOutputDirectory provide access to the directories where Maven is going to put bytecode or other build output. directory refers to the directory which contains all of these output directories.

  Object.defineProperty(Results, "Active", {value : 'true',
                       writable : true,
                       enumerable : true,
                       configurable : true});

Add a type to your variable and then return.

Eg:

const myVariable : string [] = ['hello', 'there'];

const result = myVaraible.map(x=> {
  return
  {
    x.id
  }
});

=> Important part is adding the string[] type etc:

If an array is too large to be printed, NumPy automatically skips the central part of the array and only prints the corners: To disable this behaviour and force NumPy to print the entire array, you can change the printing options using set_printoptions.

>>> np.set_printoptions(threshold='nan')

or

>>> np.set_printoptions(edgeitems=3,infstr='inf',
... linewidth=75, nanstr='nan', precision=8,
... suppress=False, threshold=1000, formatter=None)

You can also refer to the numpy documentation numpy documentation for "or part" for more help.

There are several methods to accomplish this, each of which has advantages and disadvantages; First and foremost, you're going to need to have an instance of a Worksheet object, Application.ActiveSheet works if you just want the one the user is looking at.

The Worksheet object has three properties that can be used to access cell data (Cells, Rows, Columns) and a method that can be used to obtain a block of cell data, (get_Range).

Ranges can be resized and such, but you may need to use the properties mentioned above to find out where the boundaries of your data are. The advantage to a Range becomes apparent when you are working with large amounts of data because VSTO add-ins are hosted outside the boundaries of the Excel application itself, so all calls to Excel have to be passed through a layer with overhead; obtaining a Range allows you to get/set all of the data you want in one call which can have huge performance benefits, but it requires you to use explicit details rather than iterating through each entry.

This MSDN forum post shows a VB.Net developer asking a question about getting the results of a Range as an array

Please find inner join for more than 2 table here

Here are 4 table name like

1. Orders
2. Customers
3. Student
4. Lecturer

So the SQL code would be:

select o.orderid, c.customername, l.lname, s.studadd, s.studmarks 
from orders o 
    inner join customers c on o.customrid = c.customerid 
    inner join lecturer l  on o.customrid = l.id 
    inner join student s   on o.customrid=s.studmarks;

You could use dataframe method notnull or inverse of isnull, or numpy.isnan:

In [332]: df[df.EPS.notnull()]
Out[332]:
   STK_ID  RPT_Date  STK_ID.1  EPS  cash
2  600016  20111231    600016  4.3   NaN
4  601939  20111231    601939  2.5   NaN


In [334]: df[~df.EPS.isnull()]
Out[334]:
   STK_ID  RPT_Date  STK_ID.1  EPS  cash
2  600016  20111231    600016  4.3   NaN
4  601939  20111231    601939  2.5   NaN


In [347]: df[~np.isnan(df.EPS)]
Out[347]:
   STK_ID  RPT_Date  STK_ID.1  EPS  cash
2  600016  20111231    600016  4.3   NaN
4  601939  20111231    601939  2.5   NaN

Try this.

ALTER PROCEDURE [dbo].[sp_ClientNotes_update]
    @id uniqueidentifier,
    @ordering smallint = NULL,
    @title nvarchar(20) = NULL,
    @content text = NULL
AS
BEGIN
    SET NOCOUNT ON;
    UPDATE tbl_ClientNotes
    SET ordering=ISNULL(@ordering,ordering), 
        title=ISNULL(@title,title), 
        content=ISNULL(@content, content)
    WHERE id=@id
END

It might also be worth adding an extra part to the WHERE clause, if you use transactional replication then it will send another update to the subscriber if all are NULL, to prevent this.

WHERE id=@id AND (@ordering IS NOT NULL OR
                  @title IS NOT NULL OR
                  @content IS NOT NULL)

Add it to your project/index.php file, and it will work on all over your site.

1. The only simple alternative is to actually type a new line in the variable:

   $ STR='new
   line'
   $ printf '%s' "$STR"
   new
   line
   

   Yes, that means writing Enter where needed in the code.

2. There are several equivalents to a new line character.

   \n           ### A common way to represent a new line character.
   \012         ### Octal value of a new line character.
   \x0A         ### Hexadecimal value of a new line character.
   

   But all those require "an interpretation" by some tool (POSIX printf):

   echo -e "new\nline"           ### on POSIX echo, `-e` is not required.
   printf 'new\nline'            ### Understood by POSIX printf.
   printf 'new\012line'          ### Valid in POSIX printf.
   printf 'new\x0Aline'       
   printf '%b' 'new\0012line'    ### Valid in POSIX printf.
   

   And therefore, the tool is required to build a string with a new-line:

   $ STR="$(printf 'new\nline')"
   $ printf '%s' "$STR"
   new
   line
   

3. In some shells, the sequence $' is an special shell expansion. Known to work in ksh93, bash and zsh:

   $ STR=$'new\nline'
   

4. Of course, more complex solutions are also possible:

   $ echo '6e65770a6c696e650a' | xxd -p -r
   new
   line
   

   Or

   $ echo "new line" | sed 's/ \+/\n/g'
   new
   line
   

$username = $_POST['username'];
$password = $_POST['password'];
$result = mysql_query("SELECT * FROM Users WHERE UserName LIKE '%$username%'") or die(mysql_error());

while($row = mysql_fetch_array($result))
{
    echo $row['FirstName'];
}

Sometimes suppressing the query as @mysql_query(your query);

TCPDF 5.9.010 (2010-10-27) - Support for CSS properties 'border-spacing' and 'padding' for tables were added.

The only method that worked for me is the one described here (I am running ubuntu 14.04). For the sake of clarity, these are the steps I followed:

1. sudo vim /etc/mysql/my.cnf

2. Add the following lines at the end:

   [mysqld]
   
   skip-grant-tables

3. sudo service mysql restart

4. mysql -u root

5. use mysql

6. select * from mysql.user where user = 'root'; - Look at the top to determine whether the password column is called password or authentication_string

7. UPDATE mysql.user set *password_field from above* = PASSWORD('your_new_password') where user = 'root' and host = 'localhost'; - Use the proper password column from above

8. FLUSH PRIVILEGES;

9. exit

10. sudo vim /etc/mysql/my.cnf

11. Remove the lines added in step 2 if you want to keep your security standards.

12. sudo service mysql restart

You could use numpy.fromfile, which can read data from both text and binary files. You would first construct a data type, which represents your file format, using numpy.dtype, and then read this type from file using numpy.fromfile.

As example (DEMO):

HTML:

<div class="header">
  <img src="img/logo.png" alt="logo" />
  <h1>My website name</h1>
</div>

CSS:

.header img {
  float: left;
  width: 100px;
  height: 100px;
  background: #555;
}

.header h1 {
  position: relative;
  top: 18px;
  left: 10px;
}

DEMO

Create DataTable:

DataTable MyTable = new DataTable(); // 1
DataTable MyTableByName = new DataTable("MyTableName"); // 2

Add column to table:

 MyTable.Columns.Add("Id", typeof(int));
 MyTable.Columns.Add("Name", typeof(string));

Add row to DataTable method 1:

DataRow row = MyTable.NewRow();
row["Id"] = 1;
row["Name"] = "John";
MyTable.Rows.Add(row);

Add row to DataTable method 2:

MyTable.Rows.Add(2, "Ivan");

Add row to DataTable method 3 (Add row from another table by same structure):

MyTable.ImportRow(MyTableByName.Rows[0]);

Add row to DataTable method 4 (Add row from another table):

MyTable.Rows.Add(MyTable2.Rows[0]["Id"], MyTable2.Rows[0]["Name"]);

Add row to DataTable method 5 (Insert row at an index):

MyTable.Rows.InsertAt(row, 8);

The following code may help you:

$("#svgEuropa [id='stallwanger.it.dev_shape_DEU']").on("click",function(){
    alert($(this).attr("id"));

http://rolandtapken.de/blog/2012-04/java-process-httpproxyuser-and-httpproxypassword says:

Other suggest to use a custom default Authenticator. But that's dangerous because this would send your password to anybody who asks.

This is relevant if some http/https requests don't go through the proxy (which is quite possible depending on configuration). In that case, you would send your credentials directly to some http server, not to your proxy.

He suggests the following fix.

// Java ignores http.proxyUser. Here come's the workaround.
Authenticator.setDefault(new Authenticator() {
    @Override
    protected PasswordAuthentication getPasswordAuthentication() {
        if (getRequestorType() == RequestorType.PROXY) {
            String prot = getRequestingProtocol().toLowerCase();
            String host = System.getProperty(prot + ".proxyHost", "");
            String port = System.getProperty(prot + ".proxyPort", "80");
            String user = System.getProperty(prot + ".proxyUser", "");
            String password = System.getProperty(prot + ".proxyPassword", "");

            if (getRequestingHost().equalsIgnoreCase(host)) {
                if (Integer.parseInt(port) == getRequestingPort()) {
                    // Seems to be OK.
                    return new PasswordAuthentication(user, password.toCharArray());  
                }
            }
        }
        return null;
    }  
});

I haven't tried it yet, but it looks good to me.

I modified the original version slightly to use equalsIgnoreCase() instead of equals(host.toLowerCase()) because of this: http://mattryall.net/blog/2009/02/the-infamous-turkish-locale-bug and I added "80" as the default value for port to avoid NumberFormatException in Integer.parseInt(port).

I used

Directory.GetFiles(picturePath).ToList().ForEach(File.Delete);

for delete old picture and I don't need any object in this folder

In my own implementation I found that using classes/interfaces for MI, although "good form", tended to be a massive over complication since you need to set up all that multiple inheritance for only a few necessary function calls, and in my case, needed to be done literally dozens of times redundantly.

Instead it was easier to simply make static "functions that call functions that call functions" in different modular varieties as a sort of OOP replacement. The solution I was working on was the "spell system" for a RPG where effects need to heavily mix-and-match function calling to give an extreme variety of spells without re-writing code, much like the example seems to indicate.

Most of the functions can now be static because I don't necessarily need an instance for spell logic, whereas class inheritance can't even use virtual or abstract keywords while static. Interfaces can't use them at all.

Coding seems way faster and cleaner this way IMO. If you're just doing functions, and don't need inherited properties, use functions.

Posting answer to my own question as I found it here and was hidden in bottom somewhere -

https://social.msdn.microsoft.com/Forums/vstudio/en-US/64baed8c-b00c-40d5-b19a-99b26a11516e/visual-c-redistributable-for-visual-studio-2015-rc-fails-on-windows-server-2012?forum=vssetup

This is because the OS failed to install the required update Windows8.1-KB2999226-x64.msu.

However, you can install it by extracting that update to a folder (e.g. XXXX), and execute following cmdlet. You can find the Windows8.1-KB2999226-x64.msu at below.

C:\ProgramData\Package Cache\469A82B09E217DDCF849181A586DF1C97C0C5C85\packages\Patch\amd64\Windows8.1-KB2999226-x64.msu

copy this file to a folder you like, and

Create a folder XXXX in that and execute following commands from Admin command propmt

wusa.exe Windows8.1-KB2999226-x64.msu /extract:XXXX

DISM.exe /Online /Add-Package /PackagePath:XXXX\Windows8.1-KB2999226-x64.cab

vc_redist.x64.exe /repair

(last command need not be run. Just execute vc_redist.x64.exe once again)

this worked for me.

Not sure if this is already answered, but if you want only a table in a figure window, then you can hide the axes:

fig, ax = plt.subplots()

# Hide axes
ax.xaxis.set_visible(False) 
ax.yaxis.set_visible(False)

# Table from Ed Smith answer
clust_data = np.random.random((10,3))
collabel=("col 1", "col 2", "col 3")
ax.table(cellText=clust_data,colLabels=collabel,loc='center')

If you’re deploying a large migration or need to disable access to your application for some length of time, you can use Heroku’s built in maintenance mode. It will serve a static page to all visitors, while still allowing you to run rake tasks or console commands.

$ heroku maintenance:on
Maintenance mode enabled.

and later

$ heroku maintenance:off
Maintenance mode disabled.

int range = max - min + 1;
int num = rand() % range + min;

The point is that the first line of your codes is not what you expected.

You should use:

val map = scala.collection.mutable.Map[A,B]()

You then have multiple equivalent alternatives to add items:

scala> val map = scala.collection.mutable.Map[String,String]()
map: scala.collection.mutable.Map[String,String] = Map()


scala> map("k1") = "v1"

scala> map
res1: scala.collection.mutable.Map[String,String] = Map((k1,v1))


scala> map += "k2" -> "v2"
res2: map.type = Map((k1,v1), (k2,v2))


scala> map.put("k3", "v3")
res3: Option[String] = None

scala> map
res4: scala.collection.mutable.Map[String,String] = Map((k3,v3), (k1,v1), (k2,v2))

And starting Scala 2.13:

scala> map.addOne("k4" -> "v4")
res5: map.type = HashMap(k1 -> v1, k2 -> v2, k3 -> v3, k4 -> v4)

If you don't care for IE6 and IE7 users, simply use display: table-cell for your divs:

demo

Note the use of wrapper with display: table.

For IE6/IE7 users - if you have them - you'll probably need to fallback to Javascript.

If you're using jQuery, it's as simple as this:

$('form').attr('action', 'myNewActionTarget.html');

First set

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

Go to your AppDelegate, find itsdidFinishLaunchingWithOptions method and do:

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions {

[[UIApplication sharedApplication] setStatusBarStyle:UIStatusBarStyleLightContent];

}

and then set View controller-based status bar appearance equal to NO in plist.

Range("A1").Function="=SUM(Range(Cells(2,1),Cells(3,2)))"

won't work because worksheet functions (when actually used on a worksheet) don't understand Range or Cell

Try

Range("A1").Formula="=SUM(" & Range(Cells(2,1),Cells(3,2)).Address(False,False) & ")"

This will do:

/^(apple|banana)$/

to exclude from captured strings (e.g. $1,$2):

(?:apple|banana)

With MooTools:

$('someDiv').getSize().y

STACK: Stack is defined as a list of element in which we can insert or delete elements only at the top of the stack

Stack is used to pass parameters between function. On a call to a function, the parameters and local variables are stored on a stack.

A stack is a collection of elements, which can be stored and retrieved one at a time. Elements are retrieved in reverse order of their time of storage, i.e. the latest element stored is the next element to be retrieved. A stack is sometimes referred to as a Last-In-First-Out (LIFO) or First-In-Last-Out (FILO) structure. Elements previously stored cannot be retrieved until the latest element (usually referred to as the 'top' element) has been retrieved.

QUEUE:

Queue is a collection of the same type of element. It is a linear list in which insertions can take place at one end of the list,called rear of the list, and deletions can take place only at other end, called the front of the list

A queue is a collection of elements, which can be stored and retrieved one at a time. Elements are retrieved in order of their time of storage, i.e. the first element stored is the next element to be retrieved. A queue is sometimes referred to as a First-In-First-Out (FIFO) or Last-In-Last-Out (LILO) structure. Elements subsequently stored cannot be retrieved until the first element (usually referred to as the 'front' element) has been retrieved.

Make sure MySQL binds to 0.0.0.0 and not 127.0.0.1 or it will not be accessible from outside the machine

You can ensure this by editing your my.conf file and looking for the bind-address item--you want it to look like bind-address = 0.0.0.0. Then save this and restart mysql:

sudo service mysql restart

If you are doing this on a production server, you want to be aware of the security implications, discussed here: https://serverfault.com/questions/257513/how-bad-is-setting-mysqls-bind-address-to-0-0-0-0

If you want to check the display value, https://stackoverflow.com/a/1189281/5622596 already posted the answer.

However if instead of checking whether an element has a style of style="display:none" you want to know if that element is visible. Then use .is(":visible")

For example: $('#idDetails').is(":visible");

This will be true if it is visible & false if it is not.

I have not tested this, but a multi statement function caches the result set. There may be cases where there is too much going on for the optimizer to inline the function. For example suppose you have a function that returns a result from different databases depending on what you pass as a "Company Number". Normally, you could create a view with a union all then filter by company number but I found that sometimes sql server pulls back the entire union and is not smart enough to call the one select. A table function can have logic to choose the source.

I have a local install of tensorflow 1.15.0 (with tensorboard obviously included) on MacOS.

For me, the path to the relevant file within my user directory is Library/Python/3.7/lib/python/site-packages/tensorboard/main.py. So, which does not work for me, but you have to look for the file named main.py, which is weird since it apparently is named something else for other users.

This can be addressed simple by CSS attribute:

XML: <label name="pageTac"> Hello how are you doing? Thank you I'm Good</label>

CSS

.pageText{
white-space:pre !important; // this wraps the xml text.}

HTML / XSL

<tr>
        <td class="pageText"><xsl:value-of select="$Dictionary/infolabels/label[@name='pageTac']" />
            </td></tr>

You can find the current user name with CURRENT_USER() function in MySQL.

for Ex: SELECT CURRENT_USER();

But CURRENT_USER() will not always return the logged in user. So in case you want to have the logged in user, then use SESSION_USER() instead.

There are two solutions of this issue:

The first solution is add a constructor to your component and bind your function like bellow:

constructor(props) {
        super(props);

        ...

        this.delta = this.delta.bind(this);
    }

So do this:

this.delta = this.delta.bind(this); 

Instead of this:

this.delta.bind(this);

The second solution is to use an arrow function instead:

delta = () => {
       this.setState({
           count : this.state.count++
      });
   }

Actually arrow function DOES NOT bind it’s own this. Arrow Functions lexically bind their context so this actually refers to the originating context.

Try:

<input name="mytextbox" onfocus="if (this.value=='Please describe why') this.value = ''" type="text" value="Please Describe why">

You can use lambda functions in findAll as explained in documentation. So that in your case to search for td tag with only valign = "top" use following:

td_tag_list = soup.findAll(
                lambda tag:tag.name == "td" and
                len(tag.attrs) == 1 and
                tag["valign"] == "top")

1. Click Gradle in the right side tab

2. Click the toggle offline icon (enable the Gradle online)

3. Now try building the project

   And that's it!

I had great trouble with this for devices that had vibration turned off in some manner, but we needed it to work regardless, because it is critical to our application functioning, and since it is just an integer to a documented method call, it will pass validation. So I have tried some sounds that were outside of the well documented ones here: TUNER88/iOSSystemSoundsLibrary

I have then stumbled upon 1352, which is working regardless of the silent switch or the settings on the device (Settings->vibrate on ring, vibrate on silent).

- (void)vibratePhone;
{
     if([[UIDevice currentDevice].model isEqualToString:@"iPhone"])
     {
         AudioServicesPlaySystemSound (1352); //works ALWAYS as of this post
     }
     else
     {
          // Not an iPhone, so doesn't have vibrate
          // play the less annoying tick noise or one of your own
          AudioServicesPlayAlertSound (1105);
     }
}

This regexp prevents duplicate domain names like [email protected], it will allow only domain two time like [email protected]. It also does not allow statring from number like [email protected]

 regexp: /^([a-zA-Z])+([a-zA-Z0-9_.+-])+\@(([a-zA-Z])+\.+?(com|co|in|org|net|edu|info|gov|vekomy))\.?(com|co|in|org|net|edu|info|gov)?$/, 

All The Best !!!!!

$myarray = array_values($myarray);

array_values

You Can use this -

Suppose we have a list, l = [1,2,3,4,5]

We want to delete last two items in a single statement

del l[3:]

We have output:

l = [1,2,3]

Keep it Simple

You need to publish the app before it becomes available for testing.

if you publish the app and the apk is only in "alpha testing" section then it is NOT available to general public, only for activated testers in the alpha section.

EDIT: One additional note: "normal" users will not find your app on Google Play, but also the activated tester can not find the application by using the search box.

Only the direct link to the application package will work. (only for the activated testers).

One of the simple solution could be just keep swapping the characters recursively using two pointers.

public static void main(String[] args)
{
    String str="abcdefgh";
    perm(str);
}
public static void perm(String str)
{  char[] char_arr=str.toCharArray();
    helper(char_arr,0);
}
public static void helper(char[] char_arr, int i)
{
    if(i==char_arr.length-1)
    {
        // print the shuffled string 
            String str="";
            for(int j=0; j<char_arr.length; j++)
            {
                str=str+char_arr[j];
            }
            System.out.println(str);
    }
    else
    {
    for(int j=i; j<char_arr.length; j++)
    {
        char tmp = char_arr[i];
        char_arr[i] = char_arr[j];
        char_arr[j] = tmp;
        helper(char_arr,i+1);
        char tmp1 = char_arr[i];
        char_arr[i] = char_arr[j];
        char_arr[j] = tmp1;
    }
}
}

as simple as:

find . -mtime -1 | xargs tar --no-recursion -czf myfile.tgz

where find . -mtime -1 will select all the files in (recursively) current directory modified day before. you can use fractions, for example:

find . -mtime -1.5 | xargs tar --no-recursion -czf myfile.tgz

The compiler is pointing the error to you, you're comparing a structure instance and nil. They're not of the same type so it considers it as an invalid comparison and yells at you.

What you want to do here is to compare a pointer to your config instance to nil, which is a valid comparison. To do that you can either use the golang new builtin, or initialize a pointer to it:

config := new(Config) // not nil

or

config := &Config{
                  host: "myhost.com", 
                  port: 22,
                 } // not nil

or

var config *Config // nil

Then you'll be able to check if

if config == nil {
    // then
}

Like this:

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

String[] a = list.toArray(new String[0]);

Before Java6 it was recommended to write:

String[] a = list.toArray(new String[list.size()]);

because the internal implementation would realloc a properly sized array anyway so you were better doing it upfront. Since Java6 the empty array is preferred, see .toArray(new MyClass[0]) or .toArray(new MyClass[myList.size()])?

If your list is not properly typed you need to do a cast before calling toArray. Like this:

    List l = new ArrayList<String>();

    String[] a = ((List<String>)l).toArray(new String[l.size()]);

The reason why your X-axis plots frequencies only till 500 Hz is your command statement 'f = Fs/2*linspace(0,1,NFFT/2+1);'. Your Fs is 1000. So when you divide it by 2 & then multiply by values ranging from 0 to 1, it returns a vector of length NFFT/2+1. This vector consists of equally spaced frequency values, ranging from 0 to Fs/2 (i.e. 500 Hz). Since you plot using 'plot(f,2*abs(Y(1:NFFT/2+1)))' command, your X-axis limit is 500 Hz.

in older bash (or in sh) that does not support declare -A, following style can be used to emulate key/value

# key
env=staging


# values
image_dev=gcr.io/abc/dev
image_staging=gcr.io/abc/stage
image_production=gcr.io/abc/stable

img_var_name=image_$env

# active_image=${!var_name}
active_image=$(eval "echo \$$img_var_name")

echo $active_image

Image can not be shown until it serves from any server. so you need to upload the image to your server to show its preview.

There is also the possibility of Maven using a different version of JDK, in that case you can set Maven to use the project default JDK version.

Look at the WAITFOR command.

E.g.

-- wait for 1 minute
WAITFOR DELAY '00:01'

-- wait for 1 second
WAITFOR DELAY '00:00:01'

This command allows you a high degree of precision but is only accurate within 10ms - 16ms on a typical machine as it relies on GetTickCount. So, for example, the call WAITFOR DELAY '00:00:00:001' is likely to result in no wait at all.

Something like this would work for reading:

String filename = "something.csv";
BufferedReader input = null;
List<List<String>> csvData = new ArrayList<List<String>>();
try 
{
    input =  new BufferedReader(new FileReader(filename));
    String line = null;
    while (( line = input.readLine()) != null)
    {
        String[] data = line.split(",");
        csvData.add(Arrays.toList(data));
    }
}
catch (Exception ex)
{
      ex.printStackTrace();
}
finally 
{
    if(input != null)
    {
        input.close();
    }
}

One issue with REPLACE will be where city names contain the district name. You can use something like.

SELECT SUBSTRING(O.Ort, LEN(C.CityName) + 2, 8000)
FROM   dbo.tblOrtsteileGeo O
       JOIN dbo.Cities C
         ON C.foo = O.foo
WHERE  O.GKZ = '06440004' 

It doesn't - the C# compiler does :)

So this code:

string x = "hello";
string y = "there";
string z = "chaps";
string all = x + y + z;

actually gets compiled as:

string x = "hello";
string y = "there";
string z = "chaps";
string all = string.Concat(x, y, z);

(Gah - intervening edit removed other bits accidentally.)

The benefit of the C# compiler noticing that there are multiple string concatenations here is that you don't end up creating an intermediate string of x + y which then needs to be copied again as part of the concatenation of (x + y) and z. Instead, we get it all done in one go.

EDIT: Note that the compiler can't do anything if you concatenate in a loop. For example, this code:

string x = "";
foreach (string y in strings)
{
    x += y;
}

just ends up as equivalent to:

string x = "";
foreach (string y in strings)
{
    x = string.Concat(x, y);
}

... so this does generate a lot of garbage, and it's why you should use a StringBuilder for such cases. I have an article going into more details about the two which will hopefully answer further questions.

The problem is the circular dependency between the modules. a imports b and b imports a. But one of them needs to be loaded first - in this case python ends up initializing module a before b and b.hi() doesn't exist yet when you try to access it in a.

I would advise you to use pylibmc instead.

It can act as a drop-in replacement of python-memcache, but a lot faster(as it's written in C). And you can find handy documentation for it here.

And to the question, as pylibmc just acts as a drop-in replacement, you can still refer to documentations of pylibmc for your python-memcache programming.

Some loaders (linkers) provide switches for turning dynamic loading on and off. If GCC is running on such a system (Solaris - and possibly others), then you can use the relevant option.

If you know which libraries you want to link statically, you can simply specify the static library file in the link line - by full path.
