pi@raspberrypi:~ $ 

Cutting a bit the output, we have:

pi@raspberrypi:~ $ 
pi@raspberrypi:~ $ ifconfig eth0 | grep "inet 192" | cut -c 14-25
192.168.2.24
pi@raspberrypi:~ $ 
pi@raspberrypi:~ $ 

Now, we can go to python and do:

import os
mine = os.popen('ifconfig eth0 | grep "inet 192" | cut -c 14-25')
myip = mine.read()
print (myip)

On MVC 5 you can use this:

string cIpAddress = Request.UserHostAddress; //Gets the client ip address

or

string cIpAddress = Request.ServerVariables["REMOTE_ADDR"]; //Gets the client ip address

For folks who ended up here and are using CYGWIN, install following packages in cygwin and re-run:

• cygwin32-libtool
• libtool
• libtool-debuginfo

I had this error too, my problem was in some part of code I didn't close file descriptor and in other part, I tried to open that file!! use close(fd) system call after you finished working on a file.

You can also use psql console to execute \copy without need to send file to Postgresql server machine. The command is the same:

\copy mytable [ ( column_list ) ] FROM '/path/to/csv/file' WITH CSV HEADER

This may be created sql injection point "SQL Injection Piggy-backed Queries". attackers able to append multiple malicious sql statements. so do not append user inputs directly to the queries.

Security considerations

The API functions mysqli_query() and mysqli_real_query() do not set a connection flag necessary for activating multi queries in the server. An extra API call is used for multiple statements to reduce the likeliness of accidental SQL injection attacks. An attacker may try to add statements such as ; DROP DATABASE mysql or ; SELECT SLEEP(999). If the attacker succeeds in adding SQL to the statement string but mysqli_multi_query is not used, the server will not execute the second, injected and malicious SQL statement.

PHP Doc

You can also use events in interface declarations, not so for delegates.

res.json forces the argument to JSON. res.send will take an non-json object or non-json array and send another type. For example:

This will return a JSON number.

res.json(100)

This will return a status code and issue a warning to use sendStatus.

res.send(100)

If your argument is not a JSON object or array (null,undefined,boolean,string), and you want to ensure it is sent as JSON, use res.json.

The json is kind of odd, it's like the students are properties of the "GetQuestion" object, it should be easy to be a List.....

About the libraries you could use are.

• JavaScriptSerializer
• NewtonSoft.Json
• SimpleJson ...

And there could be many more, but that are what I've used

About the json I don't now maybe something like this

public class GetQuestions
{
    public List<Student> Questions { get; set; }
}

public class Student
{
    public string Code { get; set; }
    public string Questions { get; set; }
}

void Main()
{
    var gq = new GetQuestions
    {
        Questions = new List<Student>
        {
            new Student {Code = "s1", Questions = "Q1,Q2"},
            new Student {Code = "s2", Questions = "Q1,Q2,Q3"},
            new Student {Code = "s3", Questions = "Q1,Q2,Q4"},
            new Student {Code = "s4", Questions = "Q1,Q2,Q5"},
        }
    };

    //Using Newtonsoft.json. Dump is an extension method of [Linqpad][4]
    JsonConvert.SerializeObject(gq).Dump();
}

Linqpad

and the result is this

{
     "Questions":[
        {"Code":"s1","Questions":"Q1,Q2"},
        {"Code":"s2","Questions":"Q1,Q2,Q3"},
        {"Code":"s3","Questions":"Q1,Q2,Q4"},
        {"Code":"s4","Questions":"Q1,Q2,Q5"}
      ]
 }

Yes I know the json is different, but the json that you want with dictionary.

void Main()
{
    var f = new Foo
    {
        GetQuestions = new Dictionary<string, string>
                {
                    {"s1", "Q1,Q2"},
                    {"s2", "Q1,Q2,Q3"},
                    {"s3", "Q1,Q2,Q4"},
                    {"s4", "Q1,Q2,Q4,Q6"},
                }
    };

    JsonConvert.SerializeObject(f).Dump();
}

class Foo
{
    public Dictionary<string, string> GetQuestions { get; set; }
}

And with Dictionary is as you want it.....

{
      "GetQuestions":
       {
              "s1":"Q1,Q2",
              "s2":"Q1,Q2,Q3",
              "s3":"Q1,Q2,Q4",
              "s4":"Q1,Q2,Q4,Q6"
       }
 }

'\r' means 'carriage return' and it is similar to '\n' which means 'line break' or more commonly 'new line'

in the old days of typewriters, you would have to move the carriage that writes back to the start of the line, and move the line down in order to write onto the next line.

in the modern computer era we still have this functionality for multiple reasons. but mostly we use only '\n' and automatically assume that we want to start writing from the start of the line, since it would not make much sense otherwise.

however, there are some times when we want to use JUST the '\r' and that would be if i want to write something to an output, and the instead of going down to a new line and writing something else, i want to write something over what i already wrote, this is how many programs in linux or in windows command line are able to have 'progress' information that changes on the same line.

nowadays most systems use only the '\n' to denote a newline. but some systems use both together.

you can see examples of this given in some of the other answers, but the most common are:

• windows ends lines with '\r\n'
• mac ends lines with '\r'
• unix/linux use '\n'

and some other programs also have specific uses for them.

there's two ways to return/back to the previous ViewController :

1. First case : if you used : self.navigationController?.pushViewController(yourViewController, animated: true) in this case you need to use self.navigationController?.popViewController(animated: true)
2. Second case : if you used : self.present(yourViewController, animated: true, completion: nil) in this case you need to use self.dismiss(animated: true, completion: nil)

In the first case , be sure that you embedded your ViewController to a navigationController in your storyboard

padding-left is what controls the indentation of ul not margin-left.

Compare: Here's setting padding-left to 0, notice all the indentation disappears.

ul {
  padding-left: 0;
}

<ul>
  <li>section a
    <ul>
      <li>one</li>
      <li>two</li>
      <li>three</li>
    </ul>
  </li>
</ul>
<ul>
  <li>section b
    <ul>
      <li>one</li>
      <li>two</li>
      <li>three</li>
    </ul>
  </li>
</ul>

and here's setting margin-left to 0px. Notice the indentation does NOT change.

ul {
  margin-left: 0;
}

<ul>
  <li>section a
    <ul>
      <li>one</li>
      <li>two</li>
      <li>three</li>
    </ul>
  </li>
</ul>
<ul>
  <li>section b
    <ul>
      <li>one</li>
      <li>two</li>
      <li>three</li>
    </ul>
  </li>
</ul>

The following will display all 3 buttons on the same line provided there is enough horizontal space to display them:

<button type="submit" class="msgBtn" onClick="return false;" >Save</button>
<button type="submit" class="msgBtn2" onClick="return false;">Publish</button>
<button class="msgBtnBack">Back</button>
// Note the lack of unnecessary divs, floats, etc. 

The only reason the buttons wouldn't display inline is if they have had display:block applied to them within your css.

explode does the job:

$parts = explode('.', $string);

You can also directly fetch parts of the result into variables:

list($part1, $part2) = explode('.', $string);

Look at HKLM\SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5\. One of these must be true:

• The Version value in that key should be 3.5.30729.01
• Or the SP value in the same key should be 1

In C# (taken from the first comment), you could do something along these lines:

const string name = @"SOFTWARE\Microsoft\NET Framework Setup\NDP\v3.5";
RegistryKey subKey = Registry.LocalMachine.OpenSubKey(name);
var version = subKey.GetValue("Version").ToString();
var servicePack = subKey.GetValue("SP").ToString();

For Tensorflow 2.0

import tensorflow as tf

tf.test.is_gpu_available(
    cuda_only=False,
    min_cuda_compute_capability=None
)

source here

other option is:

tf.config.experimental.list_physical_devices('GPU')

awk 'BEGIN { print strftime("%c", 1271603087); }'

$('#submenu li').hover(function(){
    $('#carousel').css('backgroundPosition', newValue);
});

One liner for Classification:

Classifying data into pre-defined categories

One liner for Clustering:

Grouping data into a set of categories

Key difference:

Classification is taking data and putting it into pre-defined categories and in Clustering the set of categories, that you want to group the data into, is not known beforehand.

Conclusion:

• Classification assigns the category to 1 new item, based on already labeled items while Clustering takes a bunch of unlabeled items and divide them into the categories
• In Classification, the categories\groups to be divided are known beforehand while in Clustering, the categories\groups to be divided are unknown beforehand
• In Classification, there are 2 phases – Training phase and then the test phase while in Clustering, there is only 1 phase – dividing of training data in clusters
• Classification is Supervised Learning while Clustering is Unsupervised Learning

I have written a long post on the same topic which you can find here:

The Maven Wrapper is an excellent choice for projects that need a specific version of Maven (or for users that don't want to install Maven at all). Instead of installing many versions of it in the operating system, we can just use the project-specific wrapper script.

mvnw: it's an executable Unix shell script used in place of a fully installed Maven

mvnw.cmd: it's for Windows environment

Use Cases

The wrapper should work with different operating systems such as:

• Linux
• OSX
• Windows
• Solaris

After that, we can run our goals like this for the Unix system:

./mvnw clean install

And the following command for Batch:

./mvnw.cmd clean install

If we don't have the specified Maven in the wrapper properties, it'll be downloaded and installed in the folder $USER_HOME/.m2/wrapper/dists of the system.

Maven Wrapper plugin

Maven Wrapper plugin to make auto installation in a simple Spring Boot project.

First, we need to go in the main folder of the project and run this command:

mvn -N io.takari:maven:wrapper

We can also specify the version of Maven:

mvn -N io.takari:maven:wrapper -Dmaven=3.5.2

The option -N means –non-recursive so that the wrapper will only be applied to the main project of the current directory, not in any submodules.

I had played a bit with super(), and had recognized that we can change calling order.

For example, we have next hierarchy structure:

    A
   / \
  B   C
   \ /
    D

In this case MRO of D will be (only for Python 3):

In [26]: D.__mro__
Out[26]: (__main__.D, __main__.B, __main__.C, __main__.A, object)

Let's create a class where super() calls after method execution.

In [23]: class A(object): #  or with Python 3 can define class A:
...:     def __init__(self):
...:         print("I'm from A")
...:  
...: class B(A):
...:      def __init__(self):
...:          print("I'm from B")
...:          super().__init__()
...:   
...: class C(A):
...:      def __init__(self):
...:          print("I'm from C")
...:          super().__init__()
...:  
...: class D(B, C):
...:      def __init__(self):
...:          print("I'm from D")
...:          super().__init__()
...: d = D()
...:
I'm from D
I'm from B
I'm from C
I'm from A

    A
   / ?
  B ? C
   ? /
    D

So we can see that resolution order is same as in MRO. But when we call super() in the beginning of the method:

In [21]: class A(object):  # or class A:
...:     def __init__(self):
...:         print("I'm from A")
...:  
...: class B(A):
...:      def __init__(self):
...:          super().__init__()  # or super(B, self).__init_()
...:          print("I'm from B")
...:   
...: class C(A):
...:      def __init__(self):
...:          super().__init__()
...:          print("I'm from C")
...:  
...: class D(B, C):
...:      def __init__(self):
...:          super().__init__()
...:          print("I'm from D")
...: d = D()
...: 
I'm from A
I'm from C
I'm from B
I'm from D

We have a different order it is reversed a order of the MRO tuple.

    A
   / ?
  B ? C
   ? /
    D

Calling .isoformat() on a date object will give you YYYY-MM-DD

from datetime import date, timedelta
(date.today() - timedelta(1)).isoformat()

++i (Prefix operation): Increments and then assigns the value
(eg): int i = 5, int b = ++i In this case, 6 is assigned to b first and then increments to 7 and so on.

i++ (Postfix operation): Assigns and then increments the value
(eg): int i = 5, int b = i++ In this case, 5 is assigned to b first and then increments to 6 and so on.

Incase of for loop: i++ is mostly used because, normally we use the starting value of i before incrementing in for loop. But depending on your program logic it may vary.

PyQt5:

from PyQt5.QtWidgets import QApplication
from PyQt5 import QtGui
from PyQt5.QtGui import QClipboard
import sys


def main():


    app=QApplication(sys.argv)
    cb = QApplication.clipboard()
    cb.clear(mode=cb.Clipboard )
    cb.setText("Copy to ClipBoard", mode=cb.Clipboard)
    sys.exit(app.exec_())

if __name__ == "__main__":
    main()

Close the first Bootstrap modal and open the new modal dynamically.

$('#Modal_One').modal('hide');
setTimeout(function () {
  $('#Modal_New').modal({
    backdrop: 'dynamic',
    keyboard: true
  });
}, 500);

you can also use rdd

it can dump & restore a running redis server and allow filter/match/rename dumps keys

The List<> constructor can accept anything which implements IEnumerable, therefore...

        object[] testArray = new object[] { "blah", "blah2" };
        List<object> testList = new List<object>(testArray);

@cmaster made the best elaborated answer. In brief:

git checkout master #
git pull # update local master from remote master
git checkout <your_branch>
git merge master # solve merge conflicts if you have`

You should not rewrite branch history instead keep them in actual state for future references. While merging to master, it creates one extra commit but that is cheap. Commits does not cost.

I tried the binding according to the answer by @Szymon but It did not work for me. I tried basicHttpsBinding which is new in .net 4.5 and It solved the issue. Here is the complete configuration that works for me.

<system.serviceModel>
    <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="false" />
    <behaviors>
      <serviceBehaviors>
        <behavior>
          <serviceMetadata httpGetEnabled="false" httpsGetEnabled="true"/>
          <serviceDebug includeExceptionDetailInFaults="true"/>
        </behavior>
      </serviceBehaviors>
    </behaviors>
    <bindings>
      <basicHttpsBinding>
        <binding name="basicHttpsBindingForYourService">
          <security mode="Transport">
            <transport clientCredentialType="None" proxyCredentialType="None"/>
          </security>
        </binding>
      </basicHttpsBinding>
    </bindings>
    <services>
      <service name="YourServiceName">
        <endpoint address="" binding="basicHttpsBinding" bindingName="basicHttpsBindingForYourService" contract="YourContract" />
      </service>
    </services>   
</system.serviceModel>

FYI: My application's target framework is 4.5.1. IIS web site that I created to deploy this wcf service only has https binding enabled.

If you want to do this via the designer you can do it by following the instructions here "Save changes is not permitted" when changing an existing column to be nullable

Here's a way to do it without turning it into a string first (based on some rudimentary benchmarking, this is about twice as fast as stringifying n first):

>>> n = 43365644
>>> [(n//(10**i))%10 for i in range(math.ceil(math.log(n, 10))-1, -1, -1)]
[4, 3, 3, 6, 5, 6, 4, 4]

Updating this after many years in response to comments of this not working for powers of 10:

[(n//(10**i))%10 for i in range(math.ceil(math.log(n, 10)), -1, -1)][bool(math.log(n,10)%1):]

The issue is that with powers of 10 (and ONLY with these), an extra step is required. ---So we use the remainder in the log_10 to determine whether to remove the leading 0--- We can't exactly use this because floating-point math errors cause this to fail for some powers of 10. So I've decided to cross the unholy river into sin and call upon regex.

In [32]: n = 43

In [33]: [(n//(10**i))%10 for i in range(math.ceil(math.log(n, 10)), -1, -1)][not(re.match('10*', str(n))):]
Out[33]: [4, 3]

In [34]: n = 1000

In [35]: [(n//(10**i))%10 for i in range(math.ceil(math.log(n, 10)), -1, -1)][not(re.match('10*', str(n))):]
Out[35]: [1, 0, 0, 0]

You can't have a link to SCSS File in your HTML page.You have to compile it down to CSS First. No there are lots of video tutorials you might want to check out. Lynda provides great video tutorials on SASS. there are also free screencasts you can google...

For official documentation visit this site http://sass-lang.com/documentation/file.SASS_REFERENCE.html And why have you chosen notepad to write Sass?? you can easily download some free text editors for better code handling.

You would write a comparator class, for example:

struct CompareAge {
    bool operator()(Person const & p1, Person const & p2) {
        // return "true" if "p1" is ordered before "p2", for example:
        return p1.age < p2.age;
    }
};

and use that as the comparator argument:

priority_queue<Person, vector<Person>, CompareAge>

Using greater gives the opposite ordering to the default less, meaning that the queue will give you the lowest value rather than the highest.

emulator-arm.exe error, couldn't run. Problem was that my laptop has 2 graphic cards and was selected only one (the performance one) from Nvidia 555M. By selecting the other graphic card from Nvidia mediu,(selected base Intel card) the emulator started!

Take a look at the Python tutorial section 4.7.3 and 4.7.4. It talks about passing tuples as arguments.

I would also consider using named parameters (and passing a dictionary) instead of using a tuple and passing a sequence. I find the use of positional arguments to be a bad practice when the positions are not intuitive or there are multiple parameters.

also you should click right button on mouse at your projectname and choose "open module settings" or press F4 button. Then on "dependencies" tab add your lib.jar to declare needed lib

here is the Guid version they have in case the link does not work later.

module System {
    export class Guid {
        constructor (public guid: string) {
            this._guid = guid;
        }

        private _guid: string;

        public ToString(): string {
            return this.guid;
        }

        // Static member
        static MakeNew(): Guid {
            var result: string;
            var i: string;
            var j: number;

            result = "";
            for (j = 0; j < 32; j++) {
                if (j == 8 || j == 12 || j == 16 || j == 20)
                    result = result + '-';
                i = Math.floor(Math.random() * 16).toString(16).toUpperCase();
                result = result + i;
            }
            return new Guid(result);
        }
    }
}

This will do the trick :-

new Date().valueOf() 

• To remove white spaces:

1) To remove white space everywhere:

df.columns = df.columns.str.replace(' ', '')

2) To remove white space at the beginning of string:

df.columns = df.columns.str.lstrip()

3) To remove white space at the end of string:

df.columns = df.columns.str.rstrip()

4) To remove white space at both ends:

df.columns = df.columns.str.strip()

• To replace white spaces with other characters (underscore for instance):

5) To replace white space everywhere

df.columns = df.columns.str.replace(' ', '_')

6) To replace white space at the beginning:

df.columns = df.columns.str.replace('^ +', '_')

7) To replace white space at the end:

df.columns = df.columns.str.replace(' +$', '_')

8) To replace white space at both ends:

df.columns = df.columns.str.replace('^ +| +$', '_')

All above applies to a specific column as well, assume you have a column named col, then just do:

df[col] = df[col].str.strip()  # or .replace as above

I found this solution in this article

.parent-element {
  -webkit-transform-style: preserve-3d;
  -moz-transform-style: preserve-3d;
  transform-style: preserve-3d;
}

.element {
  position: relative;
  top: 50%;
  transform: translateY(-50%);
}

It work like a charm if the height of element is not fixed.

You cannot define a variable of an incomplete type. You need to bring the whole definition of Cat into scope before you can create the local variable in main. I recommend that you move the definition of the type Cat to a header and include it from the translation unit that has main.

Step 1: Go to "Setting" ? find "Developer options" in System, and click.

Step 2: TURN ON "Verify apps over USB" in Debugging section.

Step 3: Try "Run app" in Android Studio again!

            and you should also TURN ON following fields inside "Developer option" .....

1: TURN ON ->"Install via USB" field

It is because Ajax is asynchronous, the success or the error function will be called later, when the server answer the client. So, just move parts depending on the result into your success function like that :

jQuery.ajax({

            type:"post",
            dataType:"json",
            url: myAjax.ajaxurl,
            data: {action: 'submit_data', info: info},
            success: function(data) {
                successmessage = 'Data was succesfully captured';
                $("label#successmessage").text(successmessage);
            },
            error: function(data) {
                successmessage = 'Error';
                $("label#successmessage").text(successmessage);
            },
        });

        $(":input").val('');
        return false;

MySQL Search & Replace Tool

Very useful web-based tool written in PHP which makes it easy to search and replace text strings in a MySQL database.

This works for me. Are you sure you're indenting with tabs?

CC = gcc
CFLAGS = -g -pedantic -O0 -std=gnu99 -m32 -Wall
PROGRAMS = digitreversal
all : $(PROGRAMS)
digitreversal : digitreversal.o
    [tab]$(CC) $(CFLAGS) -o $@ $^ $(LDFLAGS)

.PHONY: clean
clean:
    [tab]@rm -f $(PROGRAMS) *.o core

I find marking the property as readonly cleaner than the above answers. I believe vb14 is required.

Private _Name As String

Public ReadOnly Property Name() As String
    Get
        Return _Name
    End Get
End Property

This can be condensed to

Public ReadOnly Property Name As String

The other answers did not address my need for properly showing tooltips in a recent version of Jupyter inline matplotlib figure. This one works though:

import matplotlib.pyplot as plt
import numpy as np
import mplcursors
np.random.seed(42)

fig, ax = plt.subplots()
ax.scatter(*np.random.random((2, 26)))
ax.set_title("Mouse over a point")
crs = mplcursors.cursor(ax,hover=True)

crs.connect("add", lambda sel: sel.annotation.set_text(
    'Point {},{}'.format(sel.target[0], sel.target[1])))
plt.show()

Leading to something like the following picture when going over a point with mouse:

find indexes of each double quotes and insert an empty string there.

let's me give a more detail example:

import numpy as np
import matplotlib.pyplot as plt


def draw_result(lst_iter, lst_loss, lst_acc, title):
    plt.plot(lst_iter, lst_loss, '-b', label='loss')
    plt.plot(lst_iter, lst_acc, '-r', label='accuracy')

    plt.xlabel("n iteration")
    plt.legend(loc='upper left')
    plt.title(title)
    plt.savefig(title+".png")  # should before plt.show method

    plt.show()


def test_draw():
    lst_iter = range(100)
    lst_loss = [0.01 * i + 0.01 * i ** 2 for i in xrange(100)]
    # lst_loss = np.random.randn(1, 100).reshape((100, ))
    lst_acc = [0.01 * i - 0.01 * i ** 2 for i in xrange(100)]
    # lst_acc = np.random.randn(1, 100).reshape((100, ))
    draw_result(lst_iter, lst_loss, lst_acc, "sgd_method")


if __name__ == '__main__':
    test_draw()

For python3 users, to save time, use the following code,

from urllib.request import urlopen

link = "https://docs.scipy.org/doc/numpy/user/basics.broadcasting.html"

f = urlopen(link)
myfile = f.read()
print(myfile)

I know there are different threads for error: Name Error: urlopen is not defined, but thought this might save time.

If you use Mac OS X and XAMPP, let's assume that your folder with your site or API located in folder /Applications/XAMPP/xamppfiles/htdocs/API. Then you can grant access like this:

$ chmod 777 /Applications/XAMPP/xamppfiles/htdocs/API

And now open the page inside the folder:

http://localhost/API/index.php

It all depends on how big the unit of work, but I guess you're trying to treat each <product/> nodes in succession.

For that, the simplest way would be to use XMLReader to get to each node, then use SimpleXML to access them. This way, you keep the memory usage low because you're treating one node at a time and you still leverage SimpleXML's ease of use. For instance:

$z = new XMLReader;
$z->open('data.xml');

$doc = new DOMDocument;

// move to the first <product /> node
while ($z->read() && $z->name !== 'product');

// now that we're at the right depth, hop to the next <product/> until the end of the tree
while ($z->name === 'product')
{
    // either one should work
    //$node = new SimpleXMLElement($z->readOuterXML());
    $node = simplexml_import_dom($doc->importNode($z->expand(), true));

    // now you can use $node without going insane about parsing
    var_dump($node->element_1);

    // go to next <product />
    $z->next('product');
}

Quick overview of pros and cons of different approaches:

XMLReader only

• Pros: fast, uses little memory

• Cons: excessively hard to write and debug, requires lots of userland code to do anything useful. Userland code is slow and prone to error. Plus, it leaves you with more lines of code to maintain

XMLReader + SimpleXML

• Pros: doesn't use much memory (only the memory needed to process one node) and SimpleXML is, as the name implies, really easy to use.

• Cons: creating a SimpleXMLElement object for each node is not very fast. You really have to benchmark it to understand whether it's a problem for you. Even a modest machine would be able to process a thousand nodes per second, though.

XMLReader + DOM

• Pros: uses about as much memory as SimpleXML, and XMLReader::expand() is faster than creating a new SimpleXMLElement. I wish it was possible to use simplexml_import_dom() but it doesn't seem to work in that case

• Cons: DOM is annoying to work with. It's halfway between XMLReader and SimpleXML. Not as complicated and awkward as XMLReader, but light years away from working with SimpleXML.

My advice: write a prototype with SimpleXML, see if it works for you. If performance is paramount, try DOM. Stay as far away from XMLReader as possible. Remember that the more code you write, the higher the possibility of you introducing bugs or introducing performance regressions.

I was able to resolve this by adding the following to my component:

componentDidMount() {
  ReactDOM.findDOMNode(this).addEventListener('click', (event) => {
    event.stopPropagation();
  }, false);
}

@DougW has clearly answered this question, but I still like to add some codes here to explain Doug's points. (And correct errors in the code above)

Solution 1: URL-encode the POST data with a content-type header :application/x-www-form-urlencoded .

Note: you do not need to urlencode $_POST[] fields one by one, http_build_query() function can do the urlencoding job nicely.

$fields = array(
    'mediaupload'=>$file_field,
    'username'=>$_POST["username"],
    'password'=>$_POST["password"],
    'latitude'=>$_POST["latitude"],
    'longitude'=>$_POST["longitude"],
    'datetime'=>$_POST["datetime"],
    'category'=>$_POST["category"],
    'metacategory'=>$_POST["metacategory"],
    'caption'=>$_POST["description"]
);

$fields_string = http_build_query($fields);

$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST,1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$fields_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$response = curl_exec($ch);

Solution 2: Pass the array directly as the post data without URL-encoding, while the Content-Type header will be set to multipart/form-data.

$fields = array(
        'mediaupload'=>$file_field,
        'username'=>$_POST["username"],
        'password'=>$_POST["password"],
        'latitude'=>$_POST["latitude"],
        'longitude'=>$_POST["longitude"],
        'datetime'=>$_POST["datetime"],
        'category'=>$_POST["category"],
        'metacategory'=>$_POST["metacategory"],
        'caption'=>$_POST["description"]
    );

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_POST,1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,$fields);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    $response = curl_exec($ch);

Both code snippets work, but using different HTTP headers and bodies.

This is a very old thread, but I have found a pure CSS solution to this using some creative nesting. I wasn't a fan of the jQuery method at all...

Proper use of RuntimeException?

From Unchecked Exceptions -- The Controversy:

If a client can reasonably be expected to recover from an exception, make it a checked exception. If a client cannot do anything to recover from the exception, make it an unchecked exception.

Note that an unchecked exception is one derived from RuntimeException and a checked exception is one derived from Exception.

Why throw a RuntimeException if a client cannot do anything to recover from the exception? The article explains:

Runtime exceptions represent problems that are the result of a programming problem, and as such, the API client code cannot reasonably be expected to recover from them or to handle them in any way. Such problems include arithmetic exceptions, such as dividing by zero; pointer exceptions, such as trying to access an object through a null reference; and indexing exceptions, such as attempting to access an array element through an index that is too large or too small.

You can't directly call a function in another shell script.

You can move your function definitions into a separate file and then load them into your script using the . command, like this:

. /path/to/functions.sh

This will interpret functions.sh as if it's content were actually present in your file at this point. This is a common mechanism for implementing shared libraries of shell functions.

A simpler way can be :

new Thread(YourSampleClass).start();    

The correct way in .NET 4.0 is:

if (String.IsNullOrWhiteSpace(strSearch))

The String.IsNullOrWhiteSpace method used above is equivalent to:

if (strSearch == null || strSearch == String.Empty || strSearch.Trim().Length == 0) 
// String.Empty is the same as ""

Reference for IsNullOrWhiteSpace method

http://msdn.microsoft.com/en-us/library/system.string.isnullorwhitespace.aspx

Indicates whether a specified string is Nothing, empty, or consists only of white-space characters.

In earlier versions, you could do something like this:

if (String.IsNullOrEmpty(strSearch) || strSearch.Trim().Length == 0)

The String.IsNullOrEmpty method used above is equivalent to:

if (strSearch == null || strSearch == String.Empty)

Which means you still need to check for your "IsWhiteSpace" case with the .Trim().Length == 0 as per the example.

Reference for IsNullOrEmpty method

http://msdn.microsoft.com/en-us/library/system.string.isnullorempty.aspx

Indicates whether the specified string is Nothing or an Empty string.

Explanation:

You need to ensure strSearch (or any variable for that matter) is not null before you dereference it using the dot character (.) - i.e. before you do strSearch.SomeMethod() or strSearch.SomeProperty you need to check that strSearch != null.

In your example you want to make sure your string has a value, which means you want to ensure the string:

• Is not null
• Is not the empty string (String.Empty / "")
• Is not just whitespace

In the cases above, you must put the "Is it null?" case first, so it doesn't go on to check the other cases (and error) when the string is null.

Update: This answer may be incorrect or out of date. Please see comments for details.

I switched from @Inject to @EJB because @EJB allows circular injection whereas @Inject pukes on it.

Details: I needed @PostConstruct to call an @Asynchronous method but it would do so synchronously. The only way to make the asynchronous call was to have the original call a method of another bean and have it call back the method of the original bean. To do this each bean needed a reference to the other -- thus circular. @Inject failed for this task whereas @EJB worked.

If what interests you is bitwise operations look here for a brief tutorial : http://weblogs.asp.net/alessandro/archive/2007/10/02/bitwise-operators-in-c-or-xor-and-amp-amp-not.aspx .bitwise operation perform the same operations like the ones exemplified above they just work with binary representation (the operation applies to each individual bit of the value)

If you want logical operation answers are already given.

This works for me at runtime too:

UltraPictureBox1.Image = My.Resources.MyPicture

No strings involved and if I change the name it is automatically updated by refactoring.

I have to ask though, why don't you want to do this using classes?

No need to use refs, you can access using event

function handleSubmit(e) {
    e.preventDefault()
    const {username, password } = e.target.elements
    console.log({username: username.value, password: password.value })
}

<form onSubmit={handleSubmit}>
   <input type="text" id="username"/>
   <input type="text" id="password"/>
   <input type="submit" value="Login" />
</form>

If you need to perform this List.contains(Object with field value equal to x) repeatedly, a simple and efficient workaround would be:

List<field obj type> fieldOfInterestValues = new ArrayList<field obj type>;
for(Object obj : List) {
    fieldOfInterestValues.add(obj.getFieldOfInterest());
}

Then the List.contains(Object with field value equal to x) would be have the same result as fieldOfInterestValues.contains(x);

This code copies all stored procedures in the Master database to the target database, you can copy just the procedures you like by filtering the query on procedure name.

@sql is defined as nvarchar(max), @Name is the target database

DECLARE c CURSOR FOR 
   SELECT Definition
   FROM [ResiDazeMaster].[sys].[procedures] p
   INNER JOIN [ResiDazeMaster].sys.sql_modules m ON p.object_id = m.object_id

OPEN c

FETCH NEXT FROM c INTO @sql

WHILE @@FETCH_STATUS = 0 
BEGIN
   SET @sql = REPLACE(@sql,'''','''''')
   SET @sql = 'USE [' + @Name + ']; EXEC(''' + @sql + ''')'

   EXEC(@sql)

   FETCH NEXT FROM c INTO @sql
END             

CLOSE c
DEALLOCATE c

Give some time to install an SSL cert getCurrentPosition() and watchPosition() no longer work on insecure origins. To use this feature, you should consider switching your application to a secure origin, such as HTTPS.

Let me explain clearly.. If you are familiar With rdbms.. Index is database.. And index type is table.. It mean index is collection of index types., like collection of tables as database (DB).

in NOSQL.. Index is database and index type is collections. Group of collection as database..

To execute those queries... U need to install CURL for Windows.

Curl is nothing but a command line rest tool.. If you want a graphical tool.. Try

Sense plugin for chrome...

Hope it helps..

From Python documentation -> 8.3 Handling Exceptions:

A try statement may have more than one except clause, to specify handlers for different exceptions. At most one handler will be executed. Handlers only handle exceptions that occur in the corresponding try clause, not in other handlers of the same try statement. An except clause may name multiple exceptions as a parenthesized tuple, for example:

except (RuntimeError, TypeError, NameError):
    pass

Note that the parentheses around this tuple are required, because except ValueError, e: was the syntax used for what is normally written as except ValueError as e: in modern Python (described below). The old syntax is still supported for backwards compatibility. This means except RuntimeError, TypeError is not equivalent to except (RuntimeError, TypeError): but to except RuntimeError as TypeError: which is not what you want.

You should try

if (row.Table.Columns.Contains("US_OTHERFRIEND"))

I don't believe that row has a columns property itself.

Assumption:

list - List<String>

Using Java 8 Streams,

• to get first N elements from a list into a list,

  List<String> firstNElementsList = list.stream().limit(n).collect(Collectors.toList());

• to get first N elements from a list into an Array,

  String[] firstNElementsArray = list.stream().limit(n).collect(Collectors.toList()).toArray(new String[n]);

        {

            delayedDelegates.Remove(method);

Usage:

DelayedDelegate.Add(MyMethod,5);

You may define the following function

clc <- function() cat(rep("\n", 50))

which you can then call as clc().

It is definitely possible to use Javascript to change the meta tags of the page. Here is a Javascript only approach:

document.getElementsByTagName('meta')["keywords"].content = "My new page keywords!!";
document.getElementsByTagName('meta')["description"].content = "My new page description!!";
document.title = "My new Document Title!!";

I have verified that Google does index these client side changes for the code above.

For a non-recursive delete (using du and awk):

rm `du * | awk '$1 == "0" {print $2}'`

It would appear this is not possible, or at least not supported.

From the HTML5 specification:

When used to include data blocks (as opposed to scripts), the data must be embedded inline, the format of the data must be given using the type attribute, the src attribute must not be specified, and the contents of the script element must conform to the requirements defined for the format used.

UIRemoteNotificationType types = [[UIApplication sharedApplication] enabledRemoteNotificationTypes];
if (types & UIRemoteNotificationTypeAlert)
    // blah blah blah
{
    NSLog(@"Notification Enabled");
}
else
{
    NSLog(@"Notification not enabled");
}

Here we get the UIRemoteNotificationType from UIApplication. It represents the state of push notification of this app in the setting, than you can check on its type easily

Check your capitalization!

Your host system (Windows or Mac) is case insensitive by default, and Homestead inherits this behavior. Your production server on the other hand is case sensitive.

Whenever you get a ClassNotFound Exception check the following:

1. Spelling
2. Namespaces
3. Capitalization

More concise extension of @Kris's code

}

especially for using inside template code

<?php foreach (secure_iterable($values) as $value): ?>

With collections.Counter you could do

>>> import collections
>>> stats = {'a':1000, 'b':3000, 'c': 100}
>>> stats = collections.Counter(stats)
>>> stats.most_common(1)
[('b', 3000)]

If appropriate, you could simply start with an empty collections.Counter and add to it

>>> stats = collections.Counter()
>>> stats['a'] += 1

SQL Server Management Studio 2008 R2 Express commandline:

The answer by dyslexicanaboko hits the crucial point, but this one is even simpler and suited for command line (unattended scenarios):

(tried out with SQL Server 2008 R2 Express, one instance installed and having downloaded SQLManagementStudio_x64_ENU.exe)

As pointed out in this thread often enough, it is better to use the original SQL server setup (e.g. SQL Express with Tools), if possible, but there are some scenarios, where you want to add SSMS at a SQL derivative without that tools, afterwards:

I´ve already put it in a batch syntax here:

@echo off
"%~dp0SQLManagementStudio_x64_ENU.exe" /Q /ACTION="Install" /FEATURES="SSMS" /IACCEPTSQLSERVERLICENSETERMS

Remarks:

1. For 2008 without R2 it should be enough to omit the /IACCEPTSQLSERVERLICENSETERMS flag, i guess.

2. The /INDICATEPROGRESS parameter is useless here, the whole command takes a number of minutes and is 100% silent without any acknowledgement. Just look at the start menu, if the command is ready, if it has succeeded.

3. This should work for the "ADV_SSMS" Feature (instead of "SSMS") too, which is the management studio extended variant (profiling, reporting, tuning, etc.)

It depends on the shell (and its configuration) in standard bash only the command is stored without the date and time (check .bash_history if there is any timestamp there).

To have bash store the timestamp you need to set HISTTIMEFORMAT before executing the commands, e.g. in .bashrc or .bash_profile. This will cause bash to store the timestamps in .bash_history (see the entries starting with #).

Yes, it does. The way to enable this depends on your version of Notepad++. On newer versions you can use:

Menu View ? Show Symbol ? *Show All Characters`

or

Menu View ? Show Symbol ? Show White Space and TAB

(Thanks to bers' comment and bkaid's answers below for these updated locations.)

On older versions you can look for:

Menu View ? Show all characters

or

Menu View ? Show White Space and TAB

You want to do this - set a function that will be executed to respond to the onclick event:

document.getElementById('buttonLED'+id).onclick = function(){ writeLED(1,1); } ;

The things you are doing don't work because:

1. The onclick event handler expects to have a function, here you are assigning a string

   document.getElementById('buttonLED'+id).onclick = "writeLED(1,1)";
   

2. In this, you are assigning as the onclick event handler the result of executing the writeLED(1,1) function:

   document.getElementById('buttonLED'+id).onclick = writeLED(1,1);
   

You can use float on that particular div, e.g.

<div style="float:right;">

Float the div you want more space to have to the left as well:

<div style="float:left;">

If all else fails give the div on the right position:absolute and then move it as right as you want it to be.

<div style="position:absolute; left:-500px; top:30px;"> 

etc. Obviously put the style in a seperate stylesheet but this is just a quicker example.

In my case I was using jackson-databind-2.8.8.jar that is not compatible with JDK 1.6 I need to use so Spring wasn't loading this converter. I downgraded the version and it works now.

Yes, a table have one or many foreign keys and each foreign keys hava a different parent table.

same problem but very simple on Mac with brew:

• brew update
• brew install gradle

Basically you want to join two tables together where their QID columns are both not null, correct? However, you aren't enforcing any other conditions, such as that the two QID values (which seems strange to me, but ok). Something as simple as the following (tested in MySQL) seems to do what you want:

SELECT * FROM `Y` INNER JOIN `X` ON (`Y`.`QID` IS NOT NULL AND `X`.`QID` IS NOT NULL);

This gives you every non-null row in Y joined to every non-null row in X.

Update: Rico says he also wants the rows with NULL values, why not just:

SELECT * FROM `Y` INNER JOIN `X`;

Days until Christmas:

>>> import datetime
>>> today = datetime.date.today()
>>> someday = datetime.date(2008, 12, 25)
>>> diff = someday - today
>>> diff.days
86

More arithmetic here.

In case you want to use that padding space... then here's something:

You can open any of the following files:

/etc/profile
~/.bash_profile
~/.bash_login   (if .bash_profile does not exist)
~/.profile      (if .bash_login does not exist)

And add:

export PATH="$PATH:your/new/path/here"

I am having the same issue here is my scenario

i put empty('') where value is NULL now this '' value does not match with the parent table's id

here is things need to check , all value with presented in parent table otherwise remove data from parent table then try

Here is an example for shared memory :

#include <stdio.h>
#include <stdlib.h>
#include <string.h>
#include <sys/types.h>
#include <sys/ipc.h>
#include <sys/shm.h>

#define SHM_SIZE 1024  /* make it a 1K shared memory segment */

int main(int argc, char *argv[])
{
    key_t key;
    int shmid;
    char *data;
    int mode;

    if (argc > 2) {
        fprintf(stderr, "usage: shmdemo [data_to_write]\n");
        exit(1);
    }

    /* make the key: */
    if ((key = ftok("hello.txt", 'R')) == -1) /*Here the file must exist */ 
{
        perror("ftok");
        exit(1);
    }

    /*  create the segment: */
    if ((shmid = shmget(key, SHM_SIZE, 0644 | IPC_CREAT)) == -1) {
        perror("shmget");
        exit(1);
    }

    /* attach to the segment to get a pointer to it: */
    data = shmat(shmid, NULL, 0);
    if (data == (char *)(-1)) {
        perror("shmat");
        exit(1);
    }

    /* read or modify the segment, based on the command line: */
    if (argc == 2) {
        printf("writing to segment: \"%s\"\n", argv[1]);
        strncpy(data, argv[1], SHM_SIZE);
    } else
        printf("segment contains: \"%s\"\n", data);

    /* detach from the segment: */
    if (shmdt(data) == -1) {
        perror("shmdt");
        exit(1);
    }

    return 0;
}

Steps :

1. Use ftok to convert a pathname and a project identifier to a System V IPC key

2. Use shmget which allocates a shared memory segment

3. Use shmat to attache the shared memory segment identified by shmid to the address space of the calling process

4. Do the operations on the memory area

5. Detach using shmdt

The spirit of Web font is to use cache as much as possible, therefore you should use CDN version between <head></head> instead of hosting yourself:

Also, make sure you loaded your CSS AFTER the above line, or your custom font CSS won't work.

This is the answer you really want:

def Find(String,ToFind,Occurence = 1):
index = 0 
count = 0
while index <= len(String):
    try:
        if String[index:index + len(ToFind)] == ToFind:
            count += 1
        if count == Occurence:
               return index
               break
        index += 1
    except IndexError:
        return False
        break
return False

For an in-place sort, use

foo = [(list of tuples)]
foo.sort(key=lambda x:x[0]) #To sort by first element of the tuple

Using Guava (r07) you can do this:

for(char c : Lists.charactersOf(someString)) { ... }

This has the convenience of using foreach while not copying the string to a new array. Lists.charactersOf returns a view of the string as a List.

I am using nano editor in a Raspberry Pi with Italian OS language and Italian keyboard. Don't know the exact reason, but in this environment the shortcut is:

Here's the GNU version of printf... you can see it passing in stdout to vfprintf:

__printf (const char *format, ...)
{
   va_list arg;
   int done;

   va_start (arg, format);
   done = vfprintf (stdout, format, arg);
   va_end (arg);

   return done;
}

See here.

Here's a link to vfprintf... all the formatting 'magic' happens here.

The only thing that's truly 'different' about these functions is that they use varargs to get at arguments in a variable length argument list. Other than that, they're just traditional C. (This is in contrast to Pascal's printf equivalent, which is implemented with specific support in the compiler... at least it was back in the day.)

Jadaaih, you can connect send SMTP through CURL - link to Curl Developer Community.

This is Curl Email Client source.

if you're only dealing with images you can use the [getimagesize()][1] function which contains all sorts of info about the image, including the type.

A more general approach would be to use the FileInfo extension from PECL. The PHP documentation for this extension can be found at: http://us.php.net/manual/en/ref.fileinfo.php

Some people have serious complaints about that extension... so if you run into serious issues or cannot install the extension for some reason you might want to check out the deprecated function mime_content_type()

If all you need is the stdout output, then take a look at subprocess.check_output():

import subprocess

batcmd="dir"
result = subprocess.check_output(batcmd, shell=True)

Because you were using os.system(), you'd have to set shell=True to get the same behaviour. You do want to heed the security concerns about passing untrusted arguments to your shell.

If you need to capture stderr as well, simply add stderr=subprocess.STDOUT to the call:

result = subprocess.check_output([batcmd], stderr=subprocess.STDOUT)

to redirect the error output to the default output stream.

If you know that the output is text, add text=True to decode the returned bytes value with the platform default encoding; use encoding="..." instead if that codec is not correct for the data you receive.

To pass a string to the view as the Model, you can do:

public ActionResult Index()
{
    string myString = "This is my string";
    return View((object)myString);
}

You must cast it to an object so that MVC doesn't try to load the string as the view name, but instead pass it as the model. You could also write:

return View("Index", myString);

.. which is a bit more verbose.

Then in your view, just type it as a string:

@model string

<p>Value: @Model</p>

Then you can manipulate Model how you want.

For accessing it from a Layout page, it might be better to create an HtmlExtension for this:

public static string GetThemePath(this HtmlHelper helper)
{
    return "/path-to-theme";
}

Then inside your layout page:

<p>Value: @Html.GetThemePath()</p>

Hopefully you can apply this to your own scenario.

Edit: explicit HtmlHelper code:

namespace <root app namespace>
{
    public static class Helpers
    {
        public static string GetThemePath(this HtmlHelper helper)
        {
            return System.Web.Hosting.HostingEnvironment.MapPath("~") + "/path-to-theme";
        }
    }
}

Then in your view:

@{
    var path = Html.GetThemePath();
    // .. do stuff
}

Or: <p>Path: @Html.GetThemePath()</p>

Edit 2:

As discussed, the Helper will work if you add a @using statement to the top of your view, with the namespace pointing to the one that your helper is in.

It's clumsy, but you can get this from the usage messages for s_client or s_server, which are #ifed at compile time to match the supported protocol versions. Use something like

 openssl s_client -help 2>&1 | awk '/-ssl[0-9]|-tls[0-9]/{print $1}' 
 # in older releases any unknown -option will work; in 1.1.0 must be exactly -help

It is also possible to find that out using the fopen(),fseek() and ftell() function.

int get_file_size(std::string filename) // path to file
{
    FILE *p_file = NULL;
    p_file = fopen(filename.c_str(),"rb");
    fseek(p_file,0,SEEK_END);
    int size = ftell(p_file);
    fclose(p_file);
    return size;
}

The following is my favorite var_dump/print_r equivalent in Javascript to PHPs var_dump.

function dump(arr,level) {
    var dumped_text = "";
    if(!level) level = 0;
    
    //The padding given at the beginning of the line.
    var level_padding = "";
    for(var j=0;j<level+1;j++) level_padding += "    ";
    
    if(typeof(arr) == 'object') { //Array/Hashes/Objects 
        for(var item in arr) {
        var value = arr[item];
            if(typeof(value) == 'object') { //If it is an array,
                dumped_text += level_padding + "'" + item + "' ...\n";
                dumped_text += dump(value,level+1);
            } else {
                dumped_text += level_padding + "'" + item + "' => \"" + value + "\"\n";
            }
        }
    } else { //Stings/Chars/Numbers etc.
        dumped_text = "===>"+arr+"<===("+typeof(arr)+")";
    }
    return dumped_text;
}

I too, looked for a better answer, and while the solution in Edward's post is "ok", I came up with a far more natural solution in this blog post

Short and sweet:

# ---------------------------------------------------------------------------
# Name:   Invoke-Assignment
# Alias:  =
# Author: Garrett Serack (@FearTheCowboy)
# Desc:   Enables expressions like the C# operators: 
#         Ternary: 
#             <condition> ? <trueresult> : <falseresult> 
#             e.g. 
#                status = (age > 50) ? "old" : "young";
#         Null-Coalescing 
#             <value> ?? <value-if-value-is-null>
#             e.g.
#                name = GetName() ?? "No Name";
#             
# Ternary Usage:  
#         $status == ($age > 50) ? "old" : "young"
#
# Null Coalescing Usage:
#         $name = (get-name) ? "No Name" 
# ---------------------------------------------------------------------------

# returns the evaluated value of the parameter passed in, 
# executing it, if it is a scriptblock   
function eval($item) {
    if( $item -ne $null ) {
        if( $item -is "ScriptBlock" ) {
            return & $item
        }
        return $item
    }
    return $null
}

# an extended assignment function; implements logic for Ternarys and Null-Coalescing expressions
function Invoke-Assignment {
    if( $args ) {
        # ternary
        if ($p = [array]::IndexOf($args,'?' )+1) {
            if (eval($args[0])) {
                return eval($args[$p])
            } 
            return eval($args[([array]::IndexOf($args,':',$p))+1]) 
        }

        # null-coalescing
        if ($p = ([array]::IndexOf($args,'??',$p)+1)) {
            if ($result = eval($args[0])) {
                return $result
            } 
            return eval($args[$p])
        } 

        # neither ternary or null-coalescing, just a value  
        return eval($args[0])
    }
    return $null
}

# alias the function to the equals sign (which doesn't impede the normal use of = )
set-alias = Invoke-Assignment -Option AllScope -Description "FearTheCowboy's Invoke-Assignment."

Which makes it easy to do stuff like (more examples in blog post):

$message == ($age > 50) ? "Old Man" :"Young Dude" 

I use the lattice package for almost everything I plot in R and it has a corresponing plot to persp called wireframe. Let data be the way Sven defined it.

wireframe(z ~ x * y, data=data)

Or how about this (modification of fig 6.3 in Deepanyan Sarkar's book):

p <- wireframe(z ~ x * y, data=data)
npanel <- c(4, 2)
rotx <- c(-50, -80)
rotz <- seq(30, 300, length = npanel[1]+1)
update(p[rep(1, prod(npanel))], layout = npanel,
    panel = function(..., screen) {
        panel.wireframe(..., screen = list(z = rotz[current.column()],
                                           x = rotx[current.row()]))
    })

Update: Plotting surfaces with OpenGL

Since this post continues to draw attention I want to add the OpenGL way to make 3-d plots too (as suggested by @tucson below). First we need to reformat the dataset from xyz-tripplets to axis vectors x and y and a matrix z.

x <- 1:5/10
y <- 1:5
z <- x %o% y
z <- z + .2*z*runif(25) - .1*z

library(rgl)
persp3d(x, y, z, col="skyblue")

This image can be freely rotated and scaled using the mouse, or modified with additional commands, and when you are happy with it you save it using rgl.snapshot.

rgl.snapshot("myplot.png")

Using Git Bash on Windows 10 and Python36 for Windows I found the virtualenvwrapper.sh in a slightly different place and running this resolved the issue

source virtualenvwrapper.sh

You were right to look at using a set, we just need to dig in a little deeper to get your method to work.

First, the example code:

test_1 = {"foo": "bar", "FOO": "BAR"}
test_2 = {"foo": "bar", "f00": "b@r"}

We can see right now that both dictionaries contain a similar key/value pair:

{"foo": "bar", ...}

Each dictionary also contains a completely different key value pair. But how do we detect the difference? Dictionaries don't support that. Instead, you'll want to use a set.

Here is how to turn each dictionary into a set we can use:

set_1 = set(test_1.items())
set_2 = set(test_2.items())

This returns a set containing a series of tuples. Each tuple represents one key/value pair from your dictionary.

Now, to find the difference between set_1 and set_2:

print set_1 - set_2
>>> {('FOO', 'BAR')}

Want a dictionary back? Easy, just:

dict(set_1 - set_2)
>>> {'FOO': 'BAR'}

If you have a lot of HTML content (more than just a single div), you might consider building the HTML into the page within a hidden container, then updating it and making it visible when needed. This way, a large portion of your markup can be pre-parsed by the browser and avoid getting bogged down by JavaScript when called. Hope this helps!

In my case it happened cause i embedded a RecyclerView in a LinearLayout.

I previously had a layout file only containing one root RecyclerView as follows

<?xml version="1.0" encoding="utf-8"?>
<android.support.v7.widget.RecyclerView
    android:id="@+id/list"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:listitem="@layout/fragment_products"

    android:name="Products.ProductsFragment"
    app:layoutManager="LinearLayoutManager"
    tools:context=".Products.ProductsFragment"

    xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"/>

I believe the problem is within the 3 lines separated. Anyway, I think its a simple problem, ill be working on it tomorrow; thought i should write what i found before forgetting about this thread.

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

Postgres has an inbuilt mechanism for the same, which in the same query returns the id or whatever you want the query to return. here is an example. Consider you have a table created which has 2 columns column1 and column2 and you want column1 to be returned after every insert.

# create table users_table(id serial not null primary key, name character varying);
CREATE TABLE
#insert into users_table(name) VALUES ('Jon Snow') RETURNING id;?
 id 
----
  1
(1 row)

# insert into users_table(name) VALUES ('Arya Stark') RETURNING id;?
 id 
----
  2
(1 row)

If there is a good chance that the list will contain as much elements as it contains when clearing it, and if you're not in need for free memory, clearing the list is a better option. But my guess is that it probably doesn't matter. Don't try to optimize until you have detected a performance problem, and identified where it comes from.

Go to the package.json file, check the "@angular/core" version. It is an actual project version.

If you want an empty object of an interface, you can do just:

var modal = <IModal>{};

The advantage of using interfaces in lieu of classes for structuring data is that if you don't have any methods on the class, it will show in compiled JS as an empty method. Example:

class TestClass {
    a: number;
    b: string;
    c: boolean;
}

compiles into

var TestClass = (function () {
    function TestClass() {
    }
    return TestClass;
})();

which carries no value. Interfaces, on the other hand, don't show up in JS at all while still providing the benefits of data structuring and type checking.

Replace v with the name of the object you want to keep

rm(list=(ls()[ls()!="v"]))

The problem was you were trying to perform a Javascript operation on a non existing element. The element was yet to be loaded and setTimeout() gives more time for an element to load in the following ways:

1. setTimeout() causes the event to be ansynchronous therefore being executed after all the synchronous code, giving your element more time to load. Asynchronous callbacks like the callback in setTimeout() are placed in the event queue and put on the stack by the event loop after the stack of synchronous code is empty.
2. The value 0 for ms as a second argument in function setTimeout() is often slightly higher (4-10ms depending on browser). This slightly higher time needed for executing the setTimeout() callbacks is caused by the amount of 'ticks' (where a tick is pushing a callback on the stack if stack is empty) of the event loop. Because of performance and battery life reasons the amount of ticks in the event loop are restricted to a certain amount less than 1000 times per second.

Try typing this into the Node command-line environment:

.load c:/users/laura/desktop/nodeTest.js.

It should work for what you're trying to do.

If you want to call the file directly, you'd have to have it in the root directory where your Node installation resides.

"I want a Bitmap d, that is grayscale. I do see a consructor that includes System.Drawing.Imaging.PixelFormat, but I don't understand how to use that."

Here is how to do this

No, there isn't any.

For your requirement the best option would be regular expressions.

First of all check to see if your PHP installation supports CLI. Type: php -v. You can execute PHP from the command line in 2 ways:

1. php yourfile.php
2. php -r 'print("Hello world");'

I looked at Nate Barr's answer above, which you seemed to like. It doesn't seem very different from the simpler

html {background-color: grey}

Let's take an example.

Your application is located in /var/www/myApp on some Linux server

.htaccess : /var/www/myApp/.htaccess

htpasswdApp : /var/www/myApp/htpasswdApp. (You're free to use any name for .htpasswd file)

To use relative path in .htaccess:

AuthType Digest
AuthName myApp
AuthUserFile "htpasswdApp"
Require valid-user

But it will search for file in server_root directory. Not in document_root.

In out case, when application is located at /var/www/myApp :

document_root is /var/www/myApp

server_root is /etc/apache2 //(just in our example, because of we using the linux server)

You can redefine it in your apache configuration file ( /etc/apache2/apache2.conf), but I guess it's a bad idea.

So to use relative file path in your /var/www/myApp/.htaccess you should define the password's file in your server_root.

I prefer to do it by follow command:

sudo ln -s /var/www/myApp/htpasswdApp /etc/apache2/htpasswdApp

You're free to copy my command, use a hard link instead of symbol,or copy a file to your server_root.

I had the same error message when I was working with calling a stored procedure that takes two input parameters and returns 3 values using SELECT statement and I solved the issue like below in EF Code First Approach

 SqlParameter @TableName = new SqlParameter()
        {
            ParameterName = "@TableName",
            DbType = DbType.String,
            Value = "Trans"
        };

SqlParameter @FieldName = new SqlParameter()
        {
            ParameterName = "@FieldName",
            DbType = DbType.String,
            Value = "HLTransNbr"
        };


object[] parameters = new object[] { @TableName, @FieldName };

List<Sample> x = this.Database.SqlQuery<Sample>("EXEC usp_NextNumberBOGetMulti @TableName, @FieldName", parameters).ToList();


public class Sample
{
    public string TableName { get; set; }
    public string FieldName { get; set; }
    public int NextNum { get; set; }
}

UPDATE: It looks like with SQL SERVER 2005 missing EXEC keyword is creating problem. So to allow it to work with all SQL SERVER versions I updated my answer and added EXEC in below line

 List<Sample> x = this.Database.SqlQuery<Sample>(" EXEC usp_NextNumberBOGetMulti @TableName, @FieldName", param).ToList();

Use this command for Angular 6 to build

Usage depends on whether the component's parent has a layout manager or not.

• setSize() -- use when a parent layout manager does not exist;
• setPreferredSize() (also its related setMinimumSize and setMaximumSize) -- use when a parent layout manager exists.

The setSize() method probably won't do anything if the component's parent is using a layout manager; the places this will typically have an effect would be on top-level components (JFrames and JWindows) and things that are inside of scrolled panes. You also must call setSize() if you've got components inside a parent without a layout manager.

Generally, setPreferredSize() will lay out the components as expected if a layout manager is present; most layout managers work by getting the preferred (as well as minimum and maximum) sizes of their components, then using setSize() and setLocation() to position those components according to the layout's rules.

For example, a BorderLayout tries to make the bounds of its "north" region equal to the preferred size of its north component---they may end up larger or smaller than that, depending on the size of the JFrame, the size of the other components in the layout, and so on.

Because some images could have less than 500px of height, it's better to keep the auto-adjust, so i recommend the following:

<div class="carousel-inner" role="listbox" style="max-width:900px; max-height:600px !important;">`

One object may contain another as a part of its attribute.

1. document contains sentences which contain words.
2. Computer system has a hard disk, ram, processor etc.

So containment need not be physical. e.g., computer system has a warranty.

Bootstrap has a way of using media queries to define the different task for different sites. It uses four breakpoints.

we have extra small screen sizes which are less than 576 pixels that small in which I mean it's size from 576 to 768 pixels.

medium screen sizes take up screen size from 768 pixels up to 992 pixels large screen size from 992 pixels up to 1200 pixels.

E.g Small Text

This means that at the small screen between 576px and 768px, center the text For medium screen, change "sm" to "md" and same goes to large "lg"

There is a built-in function in bytearray that does what you intend.

bytearray.fromhex("de ad be ef 00")

It returns a bytearray and it reads hex strings with or without space separator.

The Thread class is used for creating and manipulating a thread in Windows.

A Task represents some asynchronous operation and is part of the Task Parallel Library, a set of APIs for running tasks asynchronously and in parallel.

In the days of old (i.e. before TPL) it used to be that using the Thread class was one of the standard ways to run code in the background or in parallel (a better alternative was often to use a ThreadPool), however this was cumbersome and had several disadvantages, not least of which was the performance overhead of creating a whole new thread to perform a task in the background.

Nowadays using tasks and the TPL is a far better solution 90% of the time as it provides abstractions which allows far more efficient use of system resources. I imagine there are a few scenarios where you want explicit control over the thread on which you are running your code, however generally speaking if you want to run something asynchronously your first port of call should be the TPL.

Most of the answers here fail to maintain JS Object key-value pairs order. If you have a form of object key-value pairs on the screen that you want to modify, for example, it is important to preserve the order of object entries.

The ES6 way of looping through the JS object and replacing key-value pair with the new pair with a modified key name would be something like:

let newWordsObject = {};

Object.keys(oldObject).forEach(key => {
  if (key === oldKey) {
    let newPair = { [newKey]: oldObject[oldKey] };
    newWordsObject = { ...newWordsObject, ...newPair }
  } else {
    newWordsObject = { ...newWordsObject, [key]: oldObject[key] }
  }
});

The solution preserves the order of entries by adding the new entry in the place of the old one.

Try this:

UIBezierPath *shadowPath = [UIBezierPath bezierPathWithRect:view.bounds];
view.layer.masksToBounds = NO;
view.layer.shadowColor = [UIColor blackColor].CGColor;
view.layer.shadowOffset = CGSizeMake(0.0f, 5.0f);
view.layer.shadowOpacity = 0.5f;
view.layer.shadowPath = shadowPath.CGPath;

First of all: The UIBezierPath used as shadowPath is crucial. If you don't use it, you might not notice a difference at first, but the keen eye will observe a certain lag occurring during events like rotating the device and/or similar. It's an important performance tweak.

Regarding your issue specifically: The important line is view.layer.masksToBounds = NO. It disables the clipping of the view's layer's sublayers that extend further than the view's bounds.

For those wondering what the difference between masksToBounds (on the layer) and the view's own clipToBounds property is: There isn't really any. Toggling one will have an effect on the other. Just a different level of abstraction.

Swift 2.2:

override func layoutSubviews()
{
    super.layoutSubviews()

    let shadowPath = UIBezierPath(rect: bounds)
    layer.masksToBounds = false
    layer.shadowColor = UIColor.blackColor().CGColor
    layer.shadowOffset = CGSizeMake(0.0, 5.0)
    layer.shadowOpacity = 0.5
    layer.shadowPath = shadowPath.CGPath
}

Swift 3:

override func layoutSubviews()
{
    super.layoutSubviews()

    let shadowPath = UIBezierPath(rect: bounds)
    layer.masksToBounds = false
    layer.shadowColor = UIColor.black.cgColor
    layer.shadowOffset = CGSize(width: 0.0, height: 5.0)
    layer.shadowOpacity = 0.5
    layer.shadowPath = shadowPath.cgPath
}

After reading many resources regarding this topic, including StackOverFlow, I find that not all solutions are working properly. Below is our attempt to fix this.

Basically, We take the friendly name of an Enum from a DescriptionAttribute if it exists.
If it does not We use RegEx to determine the words within the Enum name and add spaces.

Next version, we will use another Attribute to flag whether we can/should take the friendly name from a localizable resource file.

Below are the test cases. Please report if you have another test case that do not pass.

public static class EnumHelper
{
    public static string ToDescription(Enum value)
    {
        if (value == null)
        {

        }

        if (!Enum.IsDefined(value.GetType(), value))
        {
            return string.Empty;
        }

        FieldInfo fieldInfo = value.GetType().GetField(value.ToString());
        if (fieldInfo != null)
        {
            DescriptionAttribute[] attributes =
                fieldInfo.GetCustomAttributes(typeof (DescriptionAttribute), false) as DescriptionAttribute[];
            if (attributes != null && attributes.Length > 0)
            {
                return attributes[0].Description;
            }
        }

        return StringHelper.ToFriendlyName(value.ToString());
    }
}

public static class StringHelper
{
    public static bool IsNullOrWhiteSpace(string value)
    {
        return value == null || string.IsNullOrEmpty(value.Trim());
    }

    public static string ToFriendlyName(string value)
    {
        if (value == null) return string.Empty;
        if (value.Trim().Length == 0) return string.Empty;

        string result = value;

        result = string.Concat(result.Substring(0, 1).ToUpperInvariant(), result.Substring(1, result.Length - 1));

        const string pattern = @"([A-Z]+(?![a-z])|\d+|[A-Z][a-z]+|(?![A-Z])[a-z]+)+";

        List<string> words = new List<string>();

            }

Unicode only define code points, that is, a number which represents a character. How you store these code points in memory depends of the encoding that you are using. UTF-8 is one way of encoding Unicode characters, among many others.

Can I recommend to you to not use either?

If you want to "send" data to your screen, send a strongly typed object (A.K.A. ViewModel) because it's easier to test.

If you bind to some sort of "Model" and have random "viewbag" or "viewdata" items then it makes automated testing very difficult.

If you are using these consider how you might be able to restructure and just use ViewModels.

$.get('https://172.16.1.157:8002/firstcolumn/' + c1v + '/' + c1b, function (data) { 
  // some code...
});

Just put "https" .

You could use cursor up to delete a line, and erase text, or simply overwrite with the old text with new text.

int count = 1; 
System.out.print(String.format("\033[%dA",count)); // Move up
System.out.print("\033[2K"); // Erase line content

or clear screen

System.out.print(String.format("\033[2J"));

This is standard, but according to wikipedia the Windows console don't follow it.

In addition to existing good answers, note that Jackson 1.9 improved handling by adding "property unification", meaning that ALL annotations from difference parts of a logical property are combined, using (hopefully) intuitive precedence.

In Jackson 1.8 and prior, only field and getter annotations were used when determining what and how to serialize (writing JSON); and only and setter annotations for deserialization (reading JSON). This sometimes required addition of "extra" annotations, like annotating both getter and setter.

With Jackson 1.9 and above these extra annotations are NOT needed. It is still possible to add those; and if different names are used, one can create "split" properties (serializing using one name, deserializing using other): this is occasionally useful for sort of renaming.

This is a convention defined in RFC 2045 - Multipurpose Internet Mail Extensions (MIME) Part One: Format of Internet Message Bodies.

1. Private [subtype] values (starting with "X-") may be defined bilaterally between two cooperating agents without outside registration or standardization. Such values cannot be registered or standardized.

2. New standard values should be registered with IANA as described in RFC 2048.

A similar restriction applies to the top-level type. From the same source,

If another top-level type is to be used for any reason, it must be given a name starting with "X-" to indicate its non-standard status and to avoid a potential conflict with a future official name.

(Note that per RFC 2045, "[m]atching of media type and subtype is ALWAYS case-insensitive", so there's no difference between the interpretation of 'X-' and 'x-'.)

So it's fair to guess that "application/x-foo" was used before the IANA defined "application/foo". And it still might be used by folks who aren't aware of the IANA token assignment.

As Chris Hanson said MIME types are controlled by the IANA. This is detailed in RFC 2048 - Multipurpose Internet Mail Extensions (MIME) Part Four: Registration Procedures. According to RFC 3778, which is cited by the IANA as the definition for "application/pdf",

The application/pdf media type was first registered in 1993 by Paul Lindner for use by the gopher protocol; the registration was subsequently updated in 1994 by Steve Zilles.

The type "application/pdf" has been around for well over a decade. So it seems to me that wherever "application/x-pdf" has been used in new apps, the decision may not have been deliberate.

I had a similar heroku ssh error that I could not resolve.

As a workaround, I used the new heroku http-git feature (http transport for "heroku" remote instead of ssh). Details here: https://devcenter.heroku.com/articles/http-git

(Short version: if you have a project already setup the standard way, run heroku git:remote --http-init to change "heroku" remote to http.)

A good quick work around if you don't have time to fix/troubleshoot an ssh issue.

http://en.wikibooks.org/wiki/LaTeX/Tables#Resize_tables talks about two ways to do this.

I used:

\scalebox{0.7}{
  \begin{tabular}
    ...
  \end{tabular}
}

I came accross the same problem and solved it by checking my #includes. If you use QKeyEvent you have to make sure that you also include it.

I had a class like this and my error appeared when working with "event"in the .cpp file.

myfile.h

    #include <QKeyEvent> // adding this import solved the problem.

    class MyClass : public QWidget
    {
      Q_OBJECT

    public:
      MyClass(QWidget* parent = 0);
      virtual ~QmitkHelpOverlay();
    protected:
        virtual void  keyPressEvent(QKeyEvent* event);
    };

There are at least two ways for achieving this in base graph (my examples are for the x-axis, but work the same for the y-axis):

1. Use par(xaxp = c(x1, x2, n)) or plot(..., xaxp = c(x1, x2, n)) to define the position (x1 & x2) of the extreme tick marks and the number of intervals between the tick marks (n). Accordingly, n+1 is the number of tick marks drawn. (This works only if you use no logarithmic scale, for the behavior with logarithmic scales see ?par.)

2. You can suppress the drawing of the axis altogether and add the tick marks later with axis().
   To suppress the drawing of the axis use plot(... , xaxt = "n").
   Then call axis() with side, at, and labels: axis(side = 1, at = v1, labels = v2). With side referring to the side of the axis (1 = x-axis, 2 = y-axis), v1 being a vector containing the position of the ticks (e.g., c(1, 3, 5) if your axis ranges from 0 to 6 and you want three marks), and v2 a vector containing the labels for the specified tick marks (must be of same length as v1, e.g., c("group a", "group b", "group c")). See ?axis and my updated answer to a post on stats.stackexchange for an example of this method.

From the documentation:

list.insert(i, x)
Insert an item at a given position. The first argument is the index of the element before which to insert, so a.insert(0, x) inserts at the front of the list, and a.insert(len(a),x) is equivalent to a.append(x)

http://docs.python.org/2/tutorial/datastructures.html#more-on-lists

using as a statement automatically calls the dispose on the specified object. The object must implement the IDisposable interface. It is possible to use several objects in one statement as long as they are of the same type.

The CLR converts your code into MSIL. And the using statement gets translated into a try and finally block. This is how the using statement is represented in IL. A using statement is translated into three parts: acquisition, usage, and disposal. The resource is first acquired, then the usage is enclosed in a try statement with a finally clause. The object then gets disposed in the finally clause.

You do not embed the images in the bundle. They are called through the browser. So its;

var imgSrc = './image/image1.jpg';

return <img src={imgSrc} />

More simple way...:

    Dim dt As DataTable = DirectCast(GridView1.DataSource, DataTable)
    Dim dv As New DataView(dt)

    If GridView1.Attributes("dir") = SortDirection.Ascending Then
        dv.Sort = e.SortExpression & " DESC" 
        GridView1.Attributes("dir") = SortDirection.Descending

    Else
        GridView1.Attributes("dir") = SortDirection.Ascending
        dv.Sort = e.SortExpression & " ASC"

    End If

    GridView1.DataSource = dv
    GridView1.DataBind()

I see that this question is very old, but this is the solution I used for the same problem, and it seems to require a bit less code than the others.

As @Maloric mentioned in his answer to this question:

var jo = JObject.Parse(myJsonString);

To use JObject, you need the following in your class file

using Newtonsoft.Json.Linq;

Just tried this solution, we don't have to even write int.

int[][] twoDim = { { 1, 2 }, { 3, 7 }, { 8, 9 }, { 4, 2 }, { 5, 3 } };
Arrays.sort(twoDim, (a1,a2) -> a2[0] - a1[0]);

This thing will also work, it automatically detects the type of string.

Steps (These apply for Linux. For other OS, visit here) -

1. Copy the apk file to platform-tools in android-sdk linux folder.
2. Open Terminal and navigate to platform-tools folder in android-sdk.
3. Then Execute this command -

   ./adb install FileName.apk

4. If the operation is successful (the result is displayed on the screen), then you will find your file in the launcher of your emulator.

Well, this largely depends on how you're loading the elements needed in the 'intensive call', my initial thought is that you're doing those loads via ajax. If that's the case, then you could use the 'beforeSend' option and make an ajax call like this:

$.ajax({
  type: 'GET',
  url: "some.php",
  data: "name=John&location=Boston",

  beforeSend: function(xhr){           <---- use this option here
     $('.select_element_you_want_to_load_into').html('Loading...');
  },

  success: function(msg){
     $('.select_element_you_want_to_load_into').html(msg);
  }
});

EDIT I see, in that case, using one of the 'display:block'/'display:none' options above in conjunction with $(document).ready(...) from jQuery is probably the way to go. The $(document).ready() function waits for the entire document structure to be loaded before executing (but it doesn't wait for all media to load). You'd do something like this:

$(document).ready( function() {
  $('table#with_slow_data').show();
  $('div#loading image or text').hide();
});

I didn't see an answer that's clean and suitable for production-ready software, so here it goes:

/*
 * Get current error_reporting value,
 * so that we don't lose preferences set in php.ini and .htaccess
 * and accidently reenable message types disabled in those.
 *
 * If you want to disable e.g. E_STRICT on a global level,
 * use php.ini (or .htaccess for folder-level)
 */
$old_error_reporting = error_reporting();

/*
 * Disable E_STRICT on top of current error_reporting.
 *
 * Note: do NOT use ^ for disabling error message types,
 * as ^ will re-ENABLE the message type if it happens to be disabled already!
 */
error_reporting($old_error_reporting & ~E_STRICT);


// code that should not emit E_STRICT messages goes here


/*
 * Optional, depending on if/what code comes after.
 * Restore old settings.
 */
error_reporting($old_error_reporting);

Better way is to use "bc", an arbitrary precision calculator.

variable=$(echo "OPTIONS; OPERATIONS" | bc)

ex:

my_var=$(echo "scale=5; $temp_var/100 + $temp_var2" | bc)

where "scale=5" is accuracy.

man bc 

comes with several usage examples.

This can also be caused if you include bootstrap.js before jquery.js.

Others might have the same problem I did.

Include jQuery before bootstrap.

Even more, you can inherit generics :)

@SuppressWarnings("unchecked")
public <T extends Something<E>, E extends Enum<E> & SomethingAware> T getSomething(Class<T> clazz) {
        return (T) somethingHolderMap.get(clazz);
    }

You absolutely can, I use this approach a lot w/ both JavaScript and PHP.

Field definition:

<input type="hidden" name="foo" value="<?php echo $var;?>" />

Access w/ PHP:

$_GET['foo'] or $_POST['foo']

Also: Don't forget to sanitize your inputs if they are going into a database. Feel free to use my routine: https://github.com/niczak/PHP-Sanitize-Post/blob/master/sanitize.php

Cheers!

Specify bash instead of sh when running the script. I personally noticed they are different under ubuntu 12.10:

bash script.sh arg0 ... argn

"Bad magic number" error also happens if you have manually named your file with an extension .pyc

From the documentation of the DBNull class:

Do not confuse the notion of null in an object-oriented programming language with a DBNull object. In an object-oriented programming language, null means the absence of a reference to an object. DBNull represents an uninitialized variant or nonexistent database column.

Setting the -fx-text-fill works for me.

See below:

if (passed) {
    resultInfo.setText("Passed!");
    resultInfo.setStyle("-fx-text-fill: green; -fx-font-size: 16px;");
} else {
    resultInfo.setText("Failed!");
    resultInfo.setStyle("-fx-text-fill: red; -fx-font-size: 16px;");
}

Extend to good answer of @Cope360. To get for certain table ( incase their is same table name but different schema ), just using table OID.

select
     t.relname as table_name
    ,i.relname as index_name
    ,a.attname as column_name
    ,a.attrelid tableid

from
    pg_class t,
    pg_class i,
    pg_index ix,
    pg_attribute a
where
    t.oid = ix.indrelid
    and i.oid = ix.indexrelid
    and a.attrelid = t.oid
    and a.attnum = ANY(ix.indkey)
    and t.relkind = 'r'
    -- and t.relname like 'tbassettype'
    and a.attrelid = '"dbLegal".tbassettype'::regclass
order by
    t.relname,
    i.relname;

Explain : I have table name 'tbassettype' in both schema 'dbAsset' and 'dbLegal'. To get only table on dbLegal, just let a.attrelid = its OID.

Have a look at Styled Button it will surely help you. There are lots examples please search on INTERNET.

eg:style

<style name="Widget.Button" parent="android:Widget">
    <item name="android:background">@drawable/red_dot</item>
</style>

you can use your selector instead of red_dot

red_dot:

<?xml version="1.0" encoding="UTF-8"?>
<shape xmlns:android="http://schemas.android.com/apk/res/android"
    android:shape="oval"  >

    <solid android:color="#f00"/>
    <size android:width="55dip"
        android:height="55dip"/>
</shape>

Button:

<Button
        android:id="@+id/button1"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="49dp"
        style="@style/Widget.Button"
        android:text="Button" />

I usually create views to de-normalize and/or aggregate data frequently used for reporting purposes.

EDIT

By way of elaboration, if I were to have a database in which some of the entities were person, company, role, owner type, order, order detail, address and phone, where the person table stored both employees and contacts and the address and phone tables stored phone numbers for both persons and companies, and the development team were tasked with generating reports (or making reporting data accessible to non-developers) such as sales by employee, or sales by customer, or sales by region, sales by month, customers by state, etc I would create a set of views that de-normalized the relationships between the database entities so that a more integrated view (no pun intended) of the real world entities was available. Some of the benefits could include:

1. Reducing redundancy in writing queries
2. Establishing a standard for relating entities
3. Providing opportunities to evaluate and maximize performance for complex calculations and joins (e.g. indexing on Schemabound views in MSSQL)
4. Making data more accessible and intuitive to team members and non-developers.

The simplest way would be to first replace infs to NaN:

df.replace([np.inf, -np.inf], np.nan)

and then use the dropna:

df.replace([np.inf, -np.inf], np.nan).dropna(subset=["col1", "col2"], how="all")

For example:

In [11]: df = pd.DataFrame([1, 2, np.inf, -np.inf])

In [12]: df.replace([np.inf, -np.inf], np.nan)
Out[12]:
    0
0   1
1   2
2 NaN
3 NaN

The same method would work for a Series.

Underscore is a wildcard for something. for example 'A_%' will look for all match that Start whit 'A' and have minimum 1 extra character after that

Quick way to print something is:

select '** Place your mesage here' AS '** DEBUG:';

You are looking for grep command.

You can read 15 Practical Grep Command Examples In Linux / UNIX for some samples.

I did a quick non-scientific test in Release mode. I used two inputs: "2.34523" and "badinput" into both methods and iterated 1,000,000 times.

Valid input:

Double.TryParse = 646ms
Convert.ToDouble = 662 ms

Not much different, as expected. For all intents and purposes, for valid input, these are the same.

Invalid input:

Double.TryParse = 612ms
Convert.ToDouble = ..

Well.. it was running for a long time. I reran the entire thing using 1,000 iterations and Convert.ToDouble with bad input took 8.3 seconds. Averaging it out, it would take over 2 hours. I don't care how basic the test is, in the invalid input case, Convert.ToDouble's exception raising will ruin your performance.

So, here's another vote for TryParse with some numbers to back it up.

You can programmatically import data from a csv file in your Drive into an existing Google Sheet using Google Apps Script, replacing/appending data as needed.

Below is some sample code. It assumes that: a) you have a designated folder in your Drive where the CSV file is saved/uploaded to; b) the CSV file is named "report.csv" and the data in it comma-delimited; and c) the CSV data is imported into a designated spreadsheet. See comments in code for further details.

function importData() {
  var fSource = DriveApp.getFolderById(reports_folder_id); // reports_folder_id = id of folder where csv reports are saved
  var fi = fSource.getFilesByName('report.csv'); // latest report file
  var ss = SpreadsheetApp.openById(data_sheet_id); // data_sheet_id = id of spreadsheet that holds the data to be updated with new report data

  if ( fi.hasNext() ) { // proceed if "report.csv" file exists in the reports folder
    var file = fi.next();
    var csv = file.getBlob().getDataAsString();
    var csvData = CSVToArray(csv); // see below for CSVToArray function
    var newsheet = ss.insertSheet('NEWDATA'); // create a 'NEWDATA' sheet to store imported data
    // loop through csv data array and insert (append) as rows into 'NEWDATA' sheet
    for ( var i=0, lenCsv=csvData.length; i<lenCsv; i++ ) {
      newsheet.getRange(i+1, 1, 1, csvData[i].length).setValues(new Array(csvData[i]));
    }
    /*
    ** report data is now in 'NEWDATA' sheet in the spreadsheet - process it as needed,
    ** then delete 'NEWDATA' sheet using ss.deleteSheet(newsheet)
    */
    // rename the report.csv file so it is not processed on next scheduled run
    file.setName("report-"+(new Date().toString())+".csv");
  }
};

// This will parse a delimited string into an array of
// arrays. The default delimiter is the comma, but this
// can be overriden in the second argument.

function CSVToArray( strData, strDelimiter ) {
  // Check to see if the delimiter is defined. If not,
  // then default to COMMA.
  strDelimiter = (strDelimiter || ",");

  // Create a regular expression to parse the CSV values.
  var objPattern = new RegExp(
    (
      // Delimiters.
      "(\\" + strDelimiter + "|\\r?\\n|\\r|^)" +

      // Quoted fields.
      "(?:\"([^\"]*(?:\"\"[^\"]*)*)\"|" +

      // Standard fields.
      "([^\"\\" + strDelimiter + "\\r\\n]*))"
    ),
    "gi"
  );

  // Create an array to hold our data. Give the array
  // a default empty first row.
  var arrData = [[]];

  // Create an array to hold our individual pattern
  // matching groups.
  var arrMatches = null;

  // Keep looping over the regular expression matches
  // until we can no longer find a match.
  while (arrMatches = objPattern.exec( strData )){

    // Get the delimiter that was found.
    var strMatchedDelimiter = arrMatches[ 1 ];

    // Check to see if the given delimiter has a length
    // (is not the start of string) and if it matches
    // field delimiter. If id does not, then we know
    // that this delimiter is a row delimiter.
    if (
      strMatchedDelimiter.length &&
      (strMatchedDelimiter != strDelimiter)
    ){

      // Since we have reached a new row of data,
      // add an empty row to our data array.
      arrData.push( [] );

    }

    // Now that we have our delimiter out of the way,
    // let's check to see which kind of value we
    // captured (quoted or unquoted).
    if (arrMatches[ 2 ]){

      // We found a quoted value. When we capture
      // this value, unescape any double quotes.
      var strMatchedValue = arrMatches[ 2 ].replace(
        new RegExp( "\"\"", "g" ),
        "\""
      );

    } else {

      // We found a non-quoted value.
      var strMatchedValue = arrMatches[ 3 ];

    }

    // Now that we have our value string, let's add
    // it to the data array.
    arrData[ arrData.length - 1 ].push( strMatchedValue );
  }

  // Return the parsed data.
  return( arrData );
};

You can then create time-driven trigger in your script project to run importData() function on a regular basis (e.g. every night at 1AM), so all you have to do is put new report.csv file into the designated Drive folder, and it will be automatically processed on next scheduled run.

If you absolutely MUST work with Excel files instead of CSV, then you can use this code below. For it to work you must enable Drive API in Advanced Google Services in your script and in Developers Console (see How to Enable Advanced Services for details).

From the cygwin terminal, run this command:

echo "cd your_path" >> ~/.bashrc

The .bashrc script is run when you open a new bash session. The code above with change to the your_path directory when you open a new cygwin session.

The documentation is clear on how to do this. Let's say I have a function that takes two parameters and it will throw an error if one of them is null.

function concatStr(str1, str2) {
  const isStr1 = str1 === null
  const isStr2 = str2 === null
  if(isStr1 || isStr2) {
    throw "Parameters can't be null"
  }
  ... // Continue your code

Your test

describe("errors", () => {
  it("should error if any is null", () => {
    // Notice that the expect has a function that returns the function under test
    expect(() => concatStr(null, "test")).toThrow()
  })
})

In MySQL Workbench you can export the results of any single-table query as a list of INSERT statements. Just run the query, and then:

1. click on the floppy disk near Export/Import above the results
2. give the target file a name
3. at the bottom of the window, for Format select SQL INSERT statements
4. click Save
5. click Export

What about :

Map<String, String> s = Collections.emptyMap();

From axios docs you have baseURL and url

baseURL will be prepended to url when making requests. So you can define baseURL as http://127.0.0.1:8000 and make your requests to /url

 // `url` is the server URL that will be used for the request
 url: '/user',

 // `baseURL` will be prepended to `url` unless `url` is absolute.
 // It can be convenient to set `baseURL` for an instance of axios to pass relative URLs
 // to methods of that instance.
 baseURL: 'https://some-domain.com/api/',

Try this in web.config to replace IIS error pages. This is the best solution I guess, and it sends out the correct status code too.

<system.webServer>
  <httpErrors errorMode="Custom" existingResponse="Replace">
    <remove statusCode="404" subStatusCode="-1" />
    <remove statusCode="500" subStatusCode="-1" />
    <error statusCode="404" path="Error404.html" responseMode="File" />
    <error statusCode="500" path="Error.html" responseMode="File" />
  </httpErrors>
</system.webServer>

if you give a 2D array to the plot function of matplotlib it will assume the columns to be lines:

If x and/or y is 2-dimensional, then the corresponding columns will be plotted.

In your case your shape is not accepted (100, 1, 1, 8000). As so you can using numpy squeeze to solve the problem quickly:

np.squeez doc: Remove single-dimensional entries from the shape of an array.

import numpy as np
import matplotlib.pyplot as plt

data = np.random.randint(3, 7, (10, 1, 1, 80))
newdata = np.squeeze(data) # Shape is now: (10, 80)
plt.plot(newdata) # plotting by columns
plt.show()

But notice that 100 sets of 80 000 points is a lot of data for matplotlib. I would recommend that you look for an alternative. The result of the code example (run in Jupyter) is:

B+Trees are much easier and higher performing to do a full scan, as in look at every piece of data that the tree indexes, since the terminal nodes form a linked list. To do a full scan with a B-Tree you need to do a full tree traversal to find all the data.

B-Trees on the other hand can be faster when you do a seek (looking for a specific piece of data by key) especially when the tree resides in RAM or other non-block storage. Since you can elevate commonly used nodes in the tree there are less comparisons required to get to the data.

String.prototype.isNumeric = function() {
    var s = this.replace(',', '.').replace(/\s+/g, '');
return s == 0 || (s/s);
}

usage

'9.1'.isNumeric() -> 1
'0xabc'.isNumeric() -> 1
'10,1'.isNumeric() -> 1
'str'.isNumeric() -> NaN

I'd do this (stealing from a lot of answers here [Aaron Sterling, Wai Yip Tung, sorta from Paul McGuire] and mostly Armin Ronacher):

from itertools import tee, izip

def pairwise(iterable):
    a, b = tee(iterable)
    next(b, None)
    return izip(a, b)

def is_sorted(iterable, key=lambda a, b: a <= b):
    return all(key(a, b) for a, b in pairwise(iterable))

One nice thing: you don't have to realize the second iterable for the series (unlike with a list slice).

ok. I tried the above two ways but it didnt work for me. After trial and error i came to know that actually the file was not getting saved in 'this.state.file' variable.

fileUpload = (e) => {
    let data = e.target.files
    if(e.target.files[0]!=null){
        this.props.UserAction.fileUpload(data[0], this.fallBackMethod)
    }
}

here fileUpload is a different js file which accepts two params like this

export default (file , callback) => {
const formData = new FormData();
formData.append('fileUpload', file);

return dispatch => {
    axios.put(BaseUrl.RestUrl + "ur/url", formData)
        .then(response => {
            callback(response.data);
        }).catch(error => {
         console.log("*****  "+error)
    });
}

}

don't forget to bind method in the constructor. Let me know if you need more help in this.

Abstraction delineates a context-specific, simplified representation of something; it ignores contextually-irrelevant details and includes contextually-important details.

Encapsulation restricts outside access to something's parts and bundles that thing's state with the procedures that use the state.

Take people, for instance. In the context of surgery a useful abstraction ignores a person's religious beliefs and includes the person's body. Further, people encapsulate their memories with the thought processes that use those memories. An abstraction need not have encapsulation; for instance, a painting of a person neither hides its parts nor bundles procedures with its state. And, encapsulation need not have an associated abstraction; for instance, real people (not abstract ones) encapsulate their organs with their metabolism.

If you use eclipse, subclipse is the best I've ever used. In my opinion, this should exist as stand-alone as well... Easy to use, linked with the code and the project you have in eclipse... Just perfect for a developer who uses eclipse and wants a gui.

Personally, I prefer the command-line client, both for linux and windows.

Edit: if you use XFCE and its file manager (called Thunar), there's a plugin which works quite well. If I don't want to open the terminal, I just use that one, it has all the functionality, is fast and easy to use. There's also one for git included, though...

That seems fairly reasonable for what you're trying to do.

A slightly shorter version which leans on Python to do more of the heavy lifting might be:

for logs in mydir:

    for line in mylog:
        #...if the conditions are met
        list1.append(line)

    if any(True for line in list1 if "string" in line):
        list2.extend(list1)
    del list1

    ....

The (True for line in list1 if "string" in line) iterates over list and emits True whenever a match is found. any() uses short-circuit evaluation to return True as soon as the first True element is found. list2.extend() appends the contents of list1 to the end.

Service extends ContextWrapper which extends Context. Hence the Service is a Context. Use 'this' keyword in the service.

You may want to use the BIT data type, probably setting is as NOT NULL:

Quoting the MSDN article:

bit (Transact-SQL)

An integer data type that can take a value of 1, 0, or NULL.

The SQL Server Database Engine optimizes storage of bit columns. If there are 8 or less bit columns in a table, the columns are stored as 1 byte. If there are from 9 up to 16 bit columns, the columns are stored as 2 bytes, and so on.

The string values TRUE and FALSE can be converted to bit values: TRUE is converted to 1 and FALSE is converted to 0.

I was looking for a similar problem and found a better approach of doing this. So here it goes.

You can simply put the following line on the redirection page (say page1.php).

header("Location: URL", TRUE, 307); // Replace URL with to be redirected URL, e.g. final.php

I need this to redirect POST requests for REST API calls. This solution is able to redirect with post data as well as custom header values.

Here is the reference link.

As long as the function is written in pure R not C/C++/Fortran, one may use the following. Otherwise the best way is debugging and using "jump into":

> functionBody(functionName)
