To access the tomcat manager from different machine you have to follow bellow steps:

1. Update conf/tomcat-users.xml file with user and some roles:

<role rolename="manager-gui"/>
 <role rolename="manager-script"/>
 <role rolename="manager-jmx"/>
 <role rolename="manager-status"/>
 <user username="admin" password="admin" roles="manager-gui,manager-script,manager-jmx,manager-status"/>

Here admin user is assigning roles="manager-gui,manager-script,manager-jmx,manager-status".

Here tomcat user and password is : admin

2. Update webapps/manager/META-INF/context.xml file (Allowing IP address):

Default configuration:

<Context antiResourceLocking="false" privileged="true" >
  
  <Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1" />
  
  <Manager sessionAttributeValueClassNameFilter="java\.lang\.(?:Boolean|Integer|Long|Number|String)|org\.apache\.catalina\.filters\.CsrfPreventionFilter\$LruCache(?:\$1)?|java\.util\.(?:Linked)?HashMap"/>
</Context>

Here in Valve it is allowing only local machine IP start with 127.\d+.\d+.\d+ .

2.a : Allow specefic IP:

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow="127\.\d+\.\d+\.\d+|::1|0:0:0:0:0:0:0:1|YOUR.IP.ADDRESS.HERE" />

Here you just replace |YOUR.IP.ADDRESS.HERE with your IP address

2.b : Allow all IP:

<Valve className="org.apache.catalina.valves.RemoteAddrValve"
         allow=".*" />

Here using allow=".*" you are allowing all IP.

Thanks :)

Use ellipsize when you have fixed width, then it will automatically truncate the text & show the ellipsis at end,

it Won't work if you set layout_width as wrap_content & match_parent.

android:width="40dp"
android:ellipsize="end"
android:singleLine="true"

Flags (or compiler options) are nothing but ordinary command line arguments passed to the compiler executable.

Assuming you are invoking g++ from the command line (terminal):

$ g++ -std=c++11 your_file.cpp -o your_program

or

$ g++ -std=c++0x your_file.cpp -o your_program

if the above doesn't work.

Instead of trying to serve the node modules folder, you can also use Gulp to copy what you need to wwwroot.

https://docs.asp.net/en/latest/client-side/using-gulp.html

If you want to test against all nil/empty objects (like empty strings or empty arrays/sets) you can use the following:

static inline BOOL IsEmpty(id object) {
    return object == nil
        || ([object respondsToSelector:@selector(length)]
        && [(NSData *) object length] == 0)
        || ([object respondsToSelector:@selector(count)]
        && [(NSArray *) object count] == 0);
}

Construct your method to accept it-

public <T> void printClassNameAndCreateList(Class<T> className){
    //example access 1
    System.out.print(className.getName());

    //example access 2
    ArrayList<T> list = new ArrayList<T>();
    //note that if you create a list this way, you will have to cast input
    list.add((T)nameOfObject);
}

Call the method-

printClassNameAndCreateList(SomeClass.class);

You can also restrict the type of class, for example, this is one of the methods from a library I made-

protected Class postExceptionActivityIn;

protected <T extends PostExceptionActivity>  void  setPostExceptionActivityIn(Class <T> postExceptionActivityIn) {
    this.postExceptionActivityIn = postExceptionActivityIn;
}

Direct answer to title question:

Integers are unlimited in size and have no maximum value in Python.

Answer which addresses stated underlying use case:

According to your comment of what you're trying to do, you are currently thinking something along the lines of

minval = MAXINT;
for (i = 1; i < num_elems; i++)
    if a[i] < a[i-1]
        minval = a[i];

That's not how to think in Python. A better translation to Python (but still not the best) would be

minval = a[0]  # Just use the first value
for i in range(1, len(a)):
    minval = min(a[i], a[i - 1])

Note that the above doesn't use MAXINT at all. That part of the solution applies to any programming language: You don't need to know the highest possible value just to find the smallest value in a collection.

But anyway, what you really do in Python is just

minval = min(a)

That is, you don't write a loop at all. The built-in min() function gets the minimum of the whole collection.

I made a bash script, that given a number of parts as input, split a file

#!/bin/sh

parts_total="$2";
input="$1";

parts=$((parts_total))
for i in $(seq 0 $((parts_total-2))); do
  lines=$(wc -l "$input" | cut -f 1 -d" ")
  #n is rounded, 1.3 to 2, 1.6 to 2, 1 to 1
  n=$(awk  -v lines=$lines -v parts=$parts 'BEGIN { 
    n = lines/parts;
    rounded = sprintf("%.0f", n);
    if(n>rounded){
      print rounded + 1;
    }else{
      print rounded;
    }
  }');
  head -$n "$input" > split${i}
  tail -$((lines-n)) "$input" > .tmp${i}
  input=".tmp${i}"
  parts=$((parts-1));
done
mv .tmp$((parts_total-2)) split$((parts_total-1))
rm .tmp*

I used head and tail commands, and store in tmp files, for split the files

#10 means 10 parts
sh mysplitXparts.sh input_file 10

or with awk, where 0.1 is 10% => 10 parts, or 0.334 is 3 parts

awk -v size=$(wc -l < input) -v perc=0.1 '{
  nfile = int(NR/(size*perc)); 
  if(nfile >= 1/perc){
    nfile--;
  } 
  print > "split_"nfile
}' input

I added ExportToStream so the csv didn't have to save to the hard drive first.

public Stream ExportToStream()
{
    MemoryStream stream = new MemoryStream();
    StreamWriter writer = new StreamWriter(stream);
    writer.Write(Export(true));
    writer.Flush();
    stream.Position = 0;
    return stream;
}

I had installations of both Visual Studio 2019 and 2017. I tried installing the .NET Core 2.X SDK for VS2017 separately but with no luck.

The issue is, that I have .NET Core 3.0 SDK installed as default sdk-version, which VS2017 does not like.

My solution was to switch the SDK version for the specific project.

• First, list your installed SDK's to find the desired version:

$ dotnet --info

.NET Core SDK (reflecting any global.json):
 Version:   3.1.100
 Commit:    cd82f021f4

Runtime Environment:
 OS Name:     Windows
 OS Version:  10.0.18362
 OS Platform: Windows
 RID:         win10-x64
 Base Path:   C:\Program Files\dotnet\sdk\3.1.100\

Host (useful for support):
  Version: 3.1.0
  Commit:  65f04fb6db

.NET Core SDKs installed:
  1.1.14 [C:\Program Files\dotnet\sdk]
  2.1.202 [C:\Program Files\dotnet\sdk]
  2.1.509 [C:\Program Files\dotnet\sdk]
  2.2.110 [C:\Program Files\dotnet\sdk]
  3.0.100 [C:\Program Files\dotnet\sdk]
  3.1.100 [C:\Program Files\dotnet\sdk]

• From your solution directory:

$ dotnet new globaljson --sdk-version 2.2.110 --force

Now, dotnet will use the specified SDK version for this solution.

I have not found a way to do this system-wide without also messing up my 3.0 projects.

Few points

struct Vector y = (struct Vector*)malloc(sizeof(struct Vector)); is wrong

it should be struct Vector *y = (struct Vector*)malloc(sizeof(struct Vector)); since y holds pointer to struct Vector.

1st malloc() only allocates memory enough to hold Vector structure (which is pointer to double + int)

2nd malloc() actually allocate memory to hold 10 double.

using padding pad

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

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

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

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

using an axes divider

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

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

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

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

plt.show()

using subplots

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

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

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

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

plt.show()

Add

export PATH=$PATH:/home/me/play

to your ~/.profile and execute

As Ponies says in a comment, you cannot mix OLAP functions with aggregate functions.

Perhaps it's easier to get the last completion date for each employee, and join that to a dataset containing the last completion date for each of the three targeted courses.

This is an untested idea that should hopefully put you down the right path:

  SELECT employee_number,
         course_code,
         MAX(course_completion_date) AS max_date,
         lcc.LAST_COURSE_COMPLETED
    FROM employee_course_completion ecc
         LEFT JOIN (
             SELECT employee_number,
                    MAX(course_completion_date) AS LAST_COURSE_COMPLETED
               FROM employee_course_completion
              WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
         ) lcc
         ON lcc.employee_number = ecc.employee_number
   WHERE course_code IN ('M910303', 'M91301R', 'M91301P')
GROUP BY employee_number, course_code, lcc.LAST_COURSE_COMPLETED

Here is an example that replaces all instances of 1 or more white space characters in a column with an underscore using regular expression -

select distinct on (pd)
regexp_replace(rndc.pd, '\\s+', '_','g') as pd
from rndc14_ndc_mstr rndc;

From Standard docs., 3.6.1.2 Main Function,

In the latter form argc shall be the number of arguments passed to the program from the environment in which the program is run.If argc is nonzero these arguments shall be supplied in argv[0] through argv[argc-1] as pointers to the initial characters of null-terminated multibyte strings.....

Hope that helps..

It is called the Card Security Code (CSC) according to Wikipedia, but has also been known as other things, such as the Card Verification Value (CVV) or Card Verfication Code (CVC).

The second code, and the most cited, is CVV2 or CVC2. This CSC (also known as a CCID or Credit Card ID) is often asked for by merchants for them to secure "card not present" transactions occurring over the Internet, by mail, fax or over the phone. In many countries in Western Europe, due to increased attempts at card fraud, it is now mandatory to provide this code when the cardholder is not present in person.

Because this seems to be known by multiple names, and its name doesn't seem to be printed on the card itself, you'll probably (unfortunately) still need to tell your users how to find the code - ie by describing it as the "3 digit code on back of card".

2018 update

The situation has not improved, and is now worse - there are even more different names now. However, you can if you like use different terms depending on the card type:

• "CVC2" or "Card Validation Code" – MasterCard
• "CVV2" or "Card Verification Value 2" – Visa
• "CSC" or "Card Security Code" – American Express

Note that some American Express and Discover cards use a 4-digit code on the front of the card. See the above linked Wikipedia article for more.

EDIT: Interesting. It does appear that there is a way as several other people have listed.

1. Open Oracle VM VirtualBox Manager
2. Select the VM used by Docker
3. Click Settings -> Network
4. Adapter 1 should (default?) be "Attached to: NAT"
5. Click Advanced -> Port Forwarding
6. Add rule: Protocol TCP, Host Port 8080, Guest Port 8080 (leave Host IP and Guest IP empty)
7. Guest is your docker container and Host is your machine

You should now be able to browse to your container via localhost:8080 and your-internal-ip:8080.

I looked at this excellent info and then wondered, since

1. i have python2, python3 and IPython all installed,
2. i have PyCharm installed,
3. PyCharm uses IPython for its Python Console,

if PyCharm would use

1. IPython-py2 when Menu>File>Settings>Project>Project Interpreter == py2 AND
2. IPython-py3 when Menu>File>Settings>Project>Project Interpreter == py3

ANSWER: Yes!

P.S. i have Python Launcher for Windows installed as well.

Val is immutable and its properties are set at run time, but you can use a const modifier to make it as a compile time constant. Val in kotlin is same as final in java.

Var is mutable and its type is identified at compile time.

Modules Preconditions:

The IIS core engine uses preconditions to determine when to enable a particular module. Performance reasons, for example, might determine that you only want to execute managed modules for requests that also go to a managed handler. The precondition in the following example (precondition="managedHandler") only enables the forms authentication module for requests that are also handled by a managed handler, such as requests to .aspx or .asmx files:

<add name="FormsAuthentication" type="System.Web.Security.FormsAuthenticationModule" preCondition="managedHandler" />

If you remove the attribute precondition="managedHandler", Forms Authentication also applies to content that is not served by managed handlers, such as .html, .jpg, .doc, but also for classic ASP (.asp) or PHP (.php) extensions. See "How to Take Advantage of IIS Integrated Pipeline" for an example of enabling ASP.NET modules to run for all content.

You can also use a shortcut to enable all managed (ASP.NET) modules to run for all requests in your application, regardless of the "managedHandler" precondition.

To enable all managed modules to run for all requests without configuring each module entry to remove the "managedHandler" precondition, use the runAllManagedModulesForAllRequests property in the <modules> section:

<modules runAllManagedModulesForAllRequests="true" />    

When you use this property, the "managedHandler" precondition has no effect and all managed modules run for all requests.

Copied from IIS Modules Overview: Preconditions

By default, cin reads from the input discarding any spaces. So, all you have to do is to use a do while loop to read the input more than one time:

do {
   cout<<"Enter a number, or numbers separated by a space, between 1 and 1000."<<endl;
   cin >> num;

   // reset your variables

   // your function stuff (calculations)
}
while (true); // or some condition

Use the <button> tag instead. <button> labels are vertically centered by default.

Once you have a reference to your image, you can set its height and width like so:

var yourImg = document.getElementById('yourImgId');
if(yourImg && yourImg.style) {
    yourImg.style.height = '100px';
    yourImg.style.width = '200px';
}

In the html, it would look like this:

<img src="src/to/your/img.jpg" id="yourImgId" alt="alt tags are key!"/>

The Swiss Army knife of image lazy loading is YUI's ImageLoader.

Because there is more to this problem than simply watching the scroll position.

You need to write this in the command prompt:

set HTTP_PROXY=http://your_proxy:your_port

Like all other had said above, you need to add path. But not sure for what reason if I add C:\xampp\php in path of System Variable won't work but if I add it in path of User Variable work fine.

Although I had added and using other command line tools by adding in system variables work fine

So just in case if someone had same problem as me. Windows 10

I had the same problem using PHP and prepared statements on a VARCHAR2 column. My string didn't exceeed the VARCHAR2 size. The problem was that I used -1 as maxlength for binding, but the variable content changed later.

In example:

$sMyVariable = '';
$rParsedQuery = oci_parse($rLink, 'INSERT INTO MyTable (MyVarChar2Column) VALUES (:MYPLACEHOLDER)');
oci_bind_by_name($rParsedQuery, ':MYPLACEHOLDER', $sMyVariable, -1, SQLT_CHR);

$sMyVariable = 'a';
oci_execute($rParsedQuery, OCI_DEFAULT);
$sMyVariable = 'b';
oci_execute($rParsedQuery, OCI_DEFAULT);

If you replace the -1 with the max column width (i. e. 254) then this code works. With -1 oci_bind_by_param uses the current length of the variable content (in my case 0) as maximum length for this column. This results in ORA-01461 when executing.

We can import the Built-in URL module in node as follows

const { URL } = require('url');

Example:

undefined
> url.href
'http://localhost:1989/v3/orders'

Assuming you have something like so:

public class MyFirstClass {
   ...
   public ArrayList<Integer> myNumbers()    {
    ArrayList<Integer> numbers = new ArrayList<Integer>();
    numbers.add(5);
    numbers.add(11);
    numbers.add(3);
    return(numbers);
   }
   ...
}

You can call that method like so:

public class MySecondClass {
    ...
    MyFirstClass m1 = new MyFirstClass();
    List<Integer> myList = m1.myNumbers();
    ...
}

Since the method you are trying to call is not static, you will have to create an instance of the class which provides this method. Once you create the instance, you will then have access to the method.

Note, that in the code example above, I used this line: List<Integer> myList = m1.myNumbers();. This can be changed by the following: ArrayList<Integer> myList = m1.myNumbers();. However, it is usually recommended to program to an interface, and not to a concrete implementation, so my suggestion for the method you are using would be to do something like so:

public List<Integer> myNumbers()    {
    List<Integer> numbers = new ArrayList<Integer>();
    numbers.add(5);
    numbers.add(11);
    numbers.add(3);
    return(numbers);
   }

This will allow you to assign the contents of that list to whatever implements the List interface.

This three function are the same.

$(document).ready(function(){

}) 

and

$(function(){

}); 

and

jQuery(document).ready(function(){

});

here $ is used for define jQuery like $ = jQuery.

Now difference is that

$(document).ready is jQuery event that is fired when DOM is loaded, so it’s fired when the document structure is ready.

$(window).load event is fired after whole content is loaded like page contain images,css etc.

In my case new File() doesn't work, it causes a FileNotFoundException when run in a Jenkins pipeline job. The following code solved this, and is even easier in my opinion:

def fileContents = readFile "path/to/file"

I still don't understand this difference completely, but maybe it'll help anyone else with the same trouble. Possibly the exception was caused because new File() creates a file on the system which executes the groovy code, which was a different system than the one that contains the file I wanted to read.

If you want to do it in code, use the System.Web.HttpCookie.HttpOnly property.

This is directly from the MSDN docs:

// Create a new HttpCookie.
HttpCookie myHttpCookie = new HttpCookie("LastVisit", DateTime.Now.ToString());
// By default, the HttpOnly property is set to false 
// unless specified otherwise in configuration.
myHttpCookie.Name = "MyHttpCookie";
Response.AppendCookie(myHttpCookie);
// Show the name of the cookie.
Response.Write(myHttpCookie.Name);
// Create an HttpOnly cookie.
HttpCookie myHttpOnlyCookie = new HttpCookie("LastVisit", DateTime.Now.ToString());
// Setting the HttpOnly value to true, makes
// this cookie accessible only to ASP.NET.
myHttpOnlyCookie.HttpOnly = true;
myHttpOnlyCookie.Name = "MyHttpOnlyCookie";
Response.AppendCookie(myHttpOnlyCookie);
// Show the name of the HttpOnly cookie.
Response.Write(myHttpOnlyCookie.Name);

Doing it in code allows you to selectively choose which cookies are HttpOnly and which are not.

This is a known issue. The problem is that a div tag has the style "overflow: auto" which apparently is not implemented well with WebKit which is used by Safari and Chrome (see Emanuele Greco's answer). I did not know how to take advantage of Emanuele's suggestion to use the RS:ReportViewerHost element, but I solved it using JavaScript.

Problem

Solution

Since "overflow: auto" is specified in the style attribute of the div element with id "ctl31_ctl10", we can't override it in a stylesheet file so I resorted to JavaScript. I appended the following code to "C:\Program Files\Microsoft SQL Server\MSRS10_50.MSSQLSERVER\Reporting Services\ReportManager\js\ReportingServices.js"

function FixSafari()
{    
    var element = document.getElementById("ctl31_ctl10");
    if (element) 
    {
        element.style.overflow = "visible";  //default overflow value
    }
}

// Code from http://stackoverflow.com/questions/9434/how-do-i-add-an-additional-window-onload-event-in-javascript
if (window.addEventListener) // W3C standard
{
    window.addEventListener('load', FixSafari, false); // NB **not** 'onload'
} 
else if (window.attachEvent) // Microsoft
{
    window.attachEvent('onload', FixSafari);
}

Note

There appears to be a solution for SSRS 2005 that I have not tried but I don't think it is applicable to SSRS 2008 because I can't find the "DocMapAndReportFrame" class.

Answers are simple. No and No (No).

By the time javascript is running the concept of source files/urls from which the come is gone.

There is also no way to determine a line number because again by the time of execution the notion of code "lines" is no longer meaningful in Javascript.

Specific implementations may provide API hooks to allow priviledged code access to such details for the purpose of debugging but these APIs are not exposed to ordinary standard Javascript code.

getJSONArray(attrname) will get you an array from the object of that given attribute name in your case what is happening is that for

{"abridged_cast":["name": blah...]}
^ its trying to search for a value "characters"

but you need to get into the array and then do a search for "characters"

try this

String json="{'abridged_cast':[{'name':'JeffBridges','id':'162655890','characters':['JackPrescott']},{'name':'CharlesGrodin','id':'162662571','characters':['FredWilson']},{'name':'JessicaLange','id':'162653068','characters':['Dwan']},{'name':'JohnRandolph','id':'162691889','characters':['Capt.Ross']},{'name':'ReneAuberjonois','id':'162718328','characters':['Bagley']}]}";

    JSONObject jsonResponse;
    try {
        ArrayList<String> temp = new ArrayList<String>();
        jsonResponse = new JSONObject(json);
        JSONArray movies = jsonResponse.getJSONArray("abridged_cast");
        for(int i=0;i<movies.length();i++){
            JSONObject movie = movies.getJSONObject(i);
            JSONArray characters = movie.getJSONArray("characters");
            for(int j=0;j<characters.length();j++){
                temp.add(characters.getString(j));
            }
        }
        Toast.makeText(this, "Json: "+temp, Toast.LENGTH_LONG).show();
    } catch (JSONException e) {
        // TODO Auto-generated catch block
        e.printStackTrace();

checked it :)

Short answer: no (easy?) way, but you can do something that serves your purpose.

I've done a similar tool (a small command that, given a description of a project, sets environment, paths, directories, etc.). What I do is set-up everything and then spawn a shell with:

spawn('bash', ['-i'], {
  cwd: new_cwd,
  env: new_env,
  stdio: 'inherit'
});

After execution, you'll be on a shell with the new directory (and, in my case, environment). Of course you can change bash for whatever shell you prefer. The main differences with what you originally asked for are:

• There is an additional process, so...
• you have to write 'exit' to come back, and then...
• after existing, all changes are undone.

However, for me, that differences are desirable.

1) Add On Error Resume Next at top of the page

2) Add following code at bottom of the page

If Err.Number <> 0 Then

  Response.Write (Err.Description)   

  Response.End 

End If

On Error GoTo 0

Instead of choosing Restore Database..., select Restore Files and Filegroups...

Then enter a database name, select your .bak file path as the source, check the restore checkbox, and click Ok. If the .bak file is valid, it will work.

(The SQL Server restore option names are not intuitive for what should a very simple task.)

Mac Users please execute the below command from terminal to disable the certificate warning.

/Applications/Google\ Chrome.app/Contents/MacOS/Google\ Chrome --ignore-certificate-errors --ignore-urlfetcher-cert-requests &> /dev/null

Note that this will also have Google Chrome mark all HTTPS sites as insecure in the URL bar.

You might also try giving the full path to the binary you're trying to run. That solved my problem when trying to use ImageMagick.

As per RFC2368 which defines mailto:, further reinforced by an example in RFC1738, it is explicitly stated that the only valid way to generate a line break is with %0D%0A.

This also applies to all url schemes such as gopher, smtp, sdp, imap, ldap, etc..

You can use Template literals (Template strings)

e.g -

`"${item}"`

I write a code to read file line by line to meet my demand which different line have different data type follow articles: read-line-by-line-of-a-file-in-r and determining-number-of-linesrecords. And it should be a better solution for big file, I think. My R version (3.3.2).

con = file("pathtotargetfile", "r")
readsizeof<-2    # read size for one step to caculate number of lines in file
nooflines<-0     # number of lines
while((linesread<-length(readLines(con,readsizeof)))>0)    # calculate number of lines. Also a better solution for big file
  nooflines<-nooflines+linesread

con = file("pathtotargetfile", "r")    # open file again to variable con, since the cursor have went to the end of the file after caculating number of lines
typelist = list(0,'c',0,'c',0,0,'c',0)    # a list to specific the lines data type, which means the first line has same type with 0 (e.g. numeric)and second line has same type with 'c' (e.g. character). This meet my demand.
for(i in 1:nooflines) {
  tmp <- scan(file=con, nlines=1, what=typelist[[i]], quiet=TRUE)
  print(is.vector(tmp))
  print(tmp)
}
close(con)

(array1 + array2).uniq

This way you get array1 elements first. You will get no duplicates.

If you do not need the original list of dictionaries, you could modify it in-place with sort() method using a custom key function.

Key function:

def get_name(d):
    """ Return the value of a key in a dictionary. """

    return d["name"]

The list to be sorted:

data_one = [{'name': 'Homer', 'age': 39}, {'name': 'Bart', 'age': 10}]

Sorting it in-place:

data_one.sort(key=get_name)

If you need the original list, call the sorted() function passing it the list and the key function, then assign the returned sorted list to a new variable:

data_two = [{'name': 'Homer', 'age': 39}, {'name': 'Bart', 'age': 10}]
new_data = sorted(data_two, key=get_name)

Printing data_one and new_data.

>>> print(data_one)
[{'name': 'Bart', 'age': 10}, {'name': 'Homer', 'age': 39}]
>>> print(new_data)
[{'name': 'Bart', 'age': 10}, {'name': 'Homer', 'age': 39}]

Yes there is! After a lot of headache i found one solution to this.

Monitor.php

This php file will be monitoring the browser close event. Once the browser is closed the connection_aborted will return 1 hence the loop will break.

<?php
// Ignore user aborts and allow the script
// to run forever
ignore_user_abort(true);
set_time_limit(0);

echo connection_aborted();
while(1)
{
echo "Whatever you echo here wont be printed anywhere but it is required in order to work.";
flush();
if(connection_aborted())
{
break;
// Breaks only when browser is closed
}
}

/*
Action you want to take after browser is closed.
Write your code here
*/
?>

Caller.php

This is the file which will call Monitor.php

<?php
Header('Location: monitor.php');
?>

Parent.html

This will be the file which you will actually interact with. On loading this will directly make an AJAX call to Caller.php which will automatically start Monitor.php in background mode.

<script>

 var xmlhttp = new XMLHttpRequest();
        xmlhttp.onreadystatechange = function() {
            if (xmlhttp.readyState == 4 && xmlhttp.status == 200) {

            }
         }

   xmlhttp.open("GET", "Caller.php", true);
        xmlhttp.send();   

</script>

So the final flow is Parent.html----->Caller.php----->Monitor.php

Things seem to have changed since Angular 2.0.0

import { Observable } from 'rxjs/Observable';
import { Subscriber } from 'rxjs/Subscriber';
// ...
public fetchModel(uuid: string = undefined): Observable<string> {
  if(!uuid) {
    return new Observable<TestModel>((subscriber: Subscriber<TestModel>) => subscriber.next(new TestModel())).map(o => JSON.stringify(o));
  }
  else {
    return this.http.get("http://localhost:8080/myapp/api/model/" + uuid)
            .map(res => res.text());
  }
}

The .next() function will be called on your subscriber.

Define a helper function like this

function checkWhitespace(inputString){

    let stringArray = inputString.split(' ');

    let output = true;

    for (let el of stringArray){
        if (el!=''){
            output=false;
        }
    }

    return output;
}

Then check your input field value by passing through as an argument. If function returns true, that means value is only white space.

As an example

let inputValue = $('#firstName').val();
if(checkWhitespace(inputValue)) {
  // Show Warnings or return warnings
}else {
  // // Block of code-probably store input value into database
}

You can use brace expansion in bash:

cp /home/ankur/folder/{file1,abc,xyz} /path/to/target

Variables in Javascript don't have a type. Non-zero, non-null, non-empty and true are "true". Zero, null, undefined, empty string and false are "false".

There's a Boolean type though, as are literals true and false.

Check Database Size in SQL Server for both Azure and On-Premises-

Method 1 – Using ‘sys.database_files’ System View

SELECT
    DB_NAME() AS [database_name],
    CONCAT(CAST(SUM(
        CAST( (size * 8.0/1024) AS DECIMAL(15,2) )
    ) AS VARCHAR(20)),' MB') AS [database_size]
FROM sys.database_files;

Method 2 – Using ‘sp_spaceused’ System Stored Procedure

EXEC sp_spaceused ;

<content>(?:[^\n]*(\n+))+</content>

You can also pad the characters left by including a number following the X, such as this: string.format("0x{0:X8}", string_to_modify), which yields "0x00000C20".

Here is the general pattern:

IF(@PreviousStartDate IS NULL OR @PreviousStartDate = '')

'' is an empty string in SQL Server.

What you're trying to accomplish is called Reverse DNS lookup.

socket.gethostbyaddr("IP") 
# => (hostname, alias-list, IP)

http://docs.python.org/library/socket.html?highlight=gethostbyaddr#socket.gethostbyaddr

However, for the timeout part I have read about people running into problems with this. I would check out PyDNS or this solution for more advanced treatment.

I do it this way:

The html:

<head>
    <style type="text/css"> <? require_once('xCss.php'); ?> </style>
</head>

The xCss.php:

<? // place here your vars
$fntBtn = 'bold 14px  Arial'
$colBorder  = '#556677' ;
$colBG0     = '#dddddd' ;
$colBG1     = '#44dddd' ;
$colBtn     = '#aadddd' ;

// here goes your css after the php-close tag: 
?>
button { border: solid 1px <?= $colBorder; ?>; border-radius:4px; font: <?= $fntBtn; ?>; background-color:<?= $colBtn; ?>; } 

Computer Management->Shared Folders->Open Files

Use the double-star (aka double-splat?) operator:

func(**{'type':'Event'})

is equivalent to

func(type='Event')

If you can use pkg-config: pkg_search_module() can find OpenSSL for you.

# Search OpenSSL
find_package(PkgConfig REQUIRED)
pkg_search_module(OPENSSL REQUIRED openssl)

if( OPENSSL_FOUND )
    include_directories(${OPENSSL_INCLUDE_DIRS})
    message(STATUS "Using OpenSSL ${OPENSSL_VERSION}")
else()
    # Error; with REQUIRED, pkg_search_module() will throw an error by it's own
endif()

target_link_libraries(${YOUR_TARGET_HERE} ${OPENSSL_LIBRARIES})

There is nothing called background opacity. Opacity is applied to the element, its contents and all its child elements. And this behavior cannot be changed just by overriding the opacity in child elements.

Child vs parent opacity has been a long standing issue and the most common fix for it is using rgba(r,g,b,alpha) background colors. But in this case, since it is a background-image, that solution won't work. One solution would be to generate the image as a PNG with the required opacity in the image itself. Another solution would be to take the child div out and make it absolutely positioned.

Add android:onClick="clickEvent" to your image view.

<ImageView android:id="@+id/favorite_icon" 
    android:src="@drawable/small_star"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_gravity="top|right" android:paddingTop="63sp"
    android:paddingRight="2sp"
    android:onClick="clickEvent"  />

In your activity you can create a method with the same name (clickEvent(View v)), and that's it! You can see the log and the toast text too.

public void clickEvent(View v)
  {
    Log.i(SystemSettings.APP_TAG + " : " + HomeActivity.class.getName(), "Entered onClick method");
    Toast.makeText(v.getContext(),
            "The favorite list would appear on clicking this icon",
            Toast.LENGTH_LONG).show();
  }

This is solution without jquery.

Add Calendar and TextBox in WebForm -> Source of WebForm has this:

<asp:Calendar ID="Calendar1" runat="server" OnSelectionChanged="DateChange">
</asp:Calendar>
<asp:TextBox ID="TextBox1" runat="server"></asp:TextBox>

Create methods in cs file of WebForm:

protected void Page_Load(object sender, EventArgs e)
    {
        TextBox1.Text = DateTime.Today.ToShortDateString()+'.';
    }

    protected void DateChange(object sender, EventArgs e)
    {
        TextBox1.Text = Calendar1.SelectedDate.ToShortDateString() + '.';
    }

Method DateChange is connected with Calendar event SelectionChanged. It looks like this: DatePicker Image

SELECT * FROM sys.configurations
WHERE name = 'clr enabled'

I had an issue with margin and padding with a Button. I added Button inside a View component and apply your properties to the View.

<View style={{margin:10}}>
<Button
  title="Decrypt Data"
  color="orange"
  accessibilityLabel="Tap to Decrypt Data"
  onPress={() => {
    Alert.alert('You tapped the Decrypt button!');
  }}
  />  
</View>

You can also use the setProperty method like below

document.getElementById('divName').style.setProperty("top", "100px");

In my case, the host was unkown and instead of typing yes to the question are you sure you want to continue connecting(yes/no/[fingerprint])? I was just hitting enter .

How do I convert a list of dictionaries to a pandas DataFrame?

The other answers are correct, but not much has been explained in terms of advantages and limitations of these methods. The aim of this post will be to show examples of these methods under different situations, discuss when to use (and when not to use), and suggest alternatives.

DataFrame(), DataFrame.from_records(), and .from_dict()

Depending on the structure and format of your data, there are situations where either all three methods work, or some work better than others, or some don't work at all.

Consider a very contrived example.

np.random.seed(0)
data = pd.DataFrame(
    np.random.choice(10, (3, 4)), columns=list('ABCD')).to_dict('r')

print(data)
[{'A': 5, 'B': 0, 'C': 3, 'D': 3},
 {'A': 7, 'B': 9, 'C': 3, 'D': 5},
 {'A': 2, 'B': 4, 'C': 7, 'D': 6}]

This list consists of "records" with every keys present. This is the simplest case you could encounter.

# The following methods all produce the same output.
pd.DataFrame(data)
pd.DataFrame.from_dict(data)
pd.DataFrame.from_records(data)

   A  B  C  D
0  5  0  3  3
1  7  9  3  5
2  2  4  7  6

Word on Dictionary Orientations: orient='index'/'columns'

Before continuing, it is important to make the distinction between the different types of dictionary orientations, and support with pandas. There are two primary types: "columns", and "index".

orient='columns'
Dictionaries with the "columns" orientation will have their keys correspond to columns in the equivalent DataFrame.

For example, data above is in the "columns" orient.

data_c = [
 {'A': 5, 'B': 0, 'C': 3, 'D': 3},
 {'A': 7, 'B': 9, 'C': 3, 'D': 5},
 {'A': 2, 'B': 4, 'C': 7, 'D': 6}]

pd.DataFrame.from_dict(data_c, orient='columns')

   A  B  C  D
0  5  0  3  3
1  7  9  3  5
2  2  4  7  6

Note: If you are using pd.DataFrame.from_records, the orientation is assumed to be "columns" (you cannot specify otherwise), and the dictionaries will be loaded accordingly.

orient='index'
With this orient, keys are assumed to correspond to index values. This kind of data is best suited for pd.DataFrame.from_dict.

data_i ={
 0: {'A': 5, 'B': 0, 'C': 3, 'D': 3},
 1: {'A': 7, 'B': 9, 'C': 3, 'D': 5},
 2: {'A': 2, 'B': 4, 'C': 7, 'D': 6}}

pd.DataFrame.from_dict(data_i, orient='index')

   A  B  C  D
0  5  0  3  3
1  7  9  3  5
2  2  4  7  6

This case is not considered in the OP, but is still useful to know.

Setting Custom Index

If you need a custom index on the resultant DataFrame, you can set it using the index=... argument.

pd.DataFrame(data, index=['a', 'b', 'c'])
# pd.DataFrame.from_records(data, index=['a', 'b', 'c'])

   A  B  C  D
a  5  0  3  3
b  7  9  3  5
c  2  4  7  6

This is not supported by pd.DataFrame.from_dict.

Dealing with Missing Keys/Columns

All methods work out-of-the-box when handling dictionaries with missing keys/column values. For example,

data2 = [
     {'A': 5, 'C': 3, 'D': 3},
     {'A': 7, 'B': 9, 'F': 5},
     {'B': 4, 'C': 7, 'E': 6}]

# The methods below all produce the same output.
pd.DataFrame(data2)
pd.DataFrame.from_dict(data2)
pd.DataFrame.from_records(data2)

     A    B    C    D    E    F
0  5.0  NaN  3.0  3.0  NaN  NaN
1  7.0  9.0  NaN  NaN  NaN  5.0
2  NaN  4.0  7.0  NaN  6.0  NaN

Reading Subset of Columns

"What if I don't want to read in every single column"? You can easily specify this using the columns=... parameter.

For example, from the example dictionary of data2 above, if you wanted to read only columns "A', 'D', and 'F', you can do so by passing a list:

pd.DataFrame(data2, columns=['A', 'D', 'F'])
# pd.DataFrame.from_records(data2, columns=['A', 'D', 'F'])

     A    D    F
0  5.0  3.0  NaN
1  7.0  NaN  5.0
2  NaN  NaN  NaN

This is not supported by pd.DataFrame.from_dict with the default orient "columns".

pd.DataFrame.from_dict(data2, orient='columns', columns=['A', 'B'])

ValueError: cannot use columns parameter with orient='columns'

Reading Subset of Rows

Not supported by any of these methods directly. You will have to iterate over your data and perform a reverse delete in-place as you iterate. For example, to extract only the 0^th and 2^nd rows from data2 above, you can use:

rows_to_select = {0, 2}
for i in reversed(range(len(data2))):
    if i not in rows_to_select:
        del data2[i]

pd.DataFrame(data2)
# pd.DataFrame.from_dict(data2)
# pd.DataFrame.from_records(data2)

     A    B  C    D    E
0  5.0  NaN  3  3.0  NaN
1  NaN  4.0  7  NaN  6.0

The Panacea: json_normalize for Nested Data

A strong, robust alternative to the methods outlined above is the json_normalize function which works with lists of dictionaries (records), and in addition can also handle nested dictionaries.

pd.json_normalize(data)

   A  B  C  D
0  5  0  3  3
1  7  9  3  5
2  2  4  7  6

pd.json_normalize(data2)

     A    B  C    D    E
0  5.0  NaN  3  3.0  NaN
1  NaN  4.0  7  NaN  6.0

Again, keep in mind that the data passed to json_normalize needs to be in the list-of-dictionaries (records) format.

As mentioned, json_normalize can also handle nested dictionaries. Here's an example taken from the documentation.

data_nested = [
  {'counties': [{'name': 'Dade', 'population': 12345},
                {'name': 'Broward', 'population': 40000},
                {'name': 'Palm Beach', 'population': 60000}],
   'info': {'governor': 'Rick Scott'},
   'shortname': 'FL',
   'state': 'Florida'},
  {'counties': [{'name': 'Summit', 'population': 1234},
                {'name': 'Cuyahoga', 'population': 1337}],
   'info': {'governor': 'John Kasich'},
   'shortname': 'OH',
   'state': 'Ohio'}
]

pd.json_normalize(data_nested, 
                          record_path='counties', 
                          meta=['state', 'shortname', ['info', 'governor']])

         name  population    state shortname info.governor
0        Dade       12345  Florida        FL    Rick Scott
1     Broward       40000  Florida        FL    Rick Scott
2  Palm Beach       60000  Florida        FL    Rick Scott
3      Summit        1234     Ohio        OH   John Kasich
4    Cuyahoga        1337     Ohio        OH   John Kasich

For more information on the meta and record_path arguments, check out the documentation.

Summarising

Here's a table of all the methods discussed above, along with supported features/functionality.

_{* Use orient='columns' and then transpose to get the same effect as orient='index'.}

I'd create a cte and do an inner join. It's not efficient but it's convenient

with table as (
SELECT DATE, STATUS, TITLE, ROW_NUMBER() 
OVER (PARTITION BY DATE, STATUS,  TITLE ORDER BY QUANTITY ASC) AS Row_Num
 FROM TABLE)

select *

from table t
join select(
max(Row_Num) as Row_Num
,DATE
,STATUS
,TITLE
from table 
group by date, status, title) t2  
on t2.Row_Num = t.Row_Num and t2
and t2.date = t.date
and t2.title = t.title

If you are simply looking to make the input relative to the screen width, an easy way would be to use Dimensions:

// De structure Dimensions from React
var React = require('react-native');
var {
  ...
  Dimensions
} = React; 

// Store width in variable
var width = Dimensions.get('window').width; 

// Use width variable in style declaration
<TextInput style={{ width: width * .8 }} />

I've set up a working project here. Code is also below.

https://rnplay.org/apps/rqQPCQ

'use strict';

var React = require('react-native');
var {
  AppRegistry,
  StyleSheet,
  Text,
  View,
  TextInput,
  Dimensions
} = React;

var width = Dimensions.get('window').width;

var SampleApp = React.createClass({
  render: function() {
    return (
      <View style={styles.container}>
        <Text style={{fontSize:22}}>Percentage Width In React Native</Text>
        <View style={{marginTop:100, flexDirection: 'row',justifyContent: 'center'}}>
            <TextInput style={{backgroundColor: '#dddddd', height: 60, width: width*.8 }} />
          </View>
      </View>
    );
  }
});

var styles = StyleSheet.create({
  container: {
    flex: 1,
    marginTop:100
  },

});

AppRegistry.registerComponent('SampleApp', () => SampleApp);

Well, there are two ways of looking at it.

1. PHP code is nothing more than a set of XML processing instructions, and therefore any file with a .php extension is nothing more than an XML file that just so happens to be parsed for PHP code.
2. PHP just so happens to share the XML processing instruction format for its open and close tags. Based on that, files with .php extensions MAY be valid XML files, but they don't need to be.

If you believe the first route, then all PHP files require closing end tags. To omit them will create an invalid XML file. Then again, without having an opening <?xml version="1.0" charset="latin-1" ?> declaration, you won't have a valid XML file anyway... So it's not a major issue...

If you believe the second route, that opens the door for two types of .php files:

• Files that contain only code (library files for example)
• Files that contain native XML and also code (template files for example)

Based on that, code-only files are OK to end without a closing ?> tag. But the XML-code files are not OK to end without a closing ?> since it would invalidate the XML.

But I know what you're thinking. You're thinking what does it matter, you're never going to render a PHP file directly, so who cares if it's valid XML. Well, it does matter if you're designing a template. If it's valid XML/HTML, a normal browser will simply not display the PHP code (it's treated like a comment). So you can mock out the template without needing to run the PHP code within...

I'm not saying this is important. It's just a view that I don't see expressed too often, so what better place to share it...

Personally, I do not close tags in library files, but do in template files... I think it's a personal preference (and coding guideline) based more than anything hard...

Ctrl + Shift + A --> enter Font size --> select Increase Font Size

this will open Dialog for Enter Action or option Name

enter Fonte Size it will show selection for select Increase Font Size

Done :)

The way I fixed it: I went to the Valid OAuth Redirect URIs textbox and set the exact URL, not just the domain:

before: https://my-website.com

after: https://my-website.com/facebookoauth/facebooklogin

(the url may be different in your case, check it in the address bar of the browser).

This was caused by the setting Use Strict Mode for Redirect URIs, which was locked in the Yes position.

Main reason:SOAPMessageContext NoClassDefFoundError So you need import this Class or jar

in IDEA

1. ctrl+shift+alt+S,“Libraries”,find the absent class.
2. edit the local Maven config.

According to this code golfing solution by Gaffi, the following works:

a = Split(StrConv(s, 64), Chr(0))

I had the same problem trying to port a Go program to C#. This means that a lot of data has already been encrypted with the Go program. This data must now be decrypted with C#.

The final solution was PaddingMode.None or rather PaddingMode.Zeros.

The cryptographic methods in Go:

import (
    "crypto/aes"
    "crypto/cipher"
    "crypto/sha1"
    "encoding/base64"
    "io/ioutil"
    "log"

    "golang.org/x/crypto/pbkdf2"
)

Now, decryption in C#:

public static string FromFile(string filename, byte[] saltBytes, string masterPassword)
{
    var iterations = 6;
    var keyLength = 256;
    var blockSize = 128;
    var result = string.Empty;
    var encryptedBytesBase64 = File.ReadAllBytes(filename);

    // bytes -> string:
    var encryptedBytesBase64String = System.Text.Encoding.UTF8.GetString(encryptedBytesBase64);

    // Decode base64:
    var encryptedBytes = Convert.FromBase64String(encryptedBytesBase64String);
    var keyVectorObj = new Rfc2898DeriveBytes(masterPassword, saltBytes.Length, iterations);
    keyVectorObj.Salt = saltBytes;
    Span<byte> keyVectorData = keyVectorObj.GetBytes(keyLength / 8 + blockSize / 8);
    var key = keyVectorData.Slice(0, keyLength / 8);
    var iv = keyVectorData.Slice(keyLength / 8);

    var aes = Aes.Create();
    aes.Padding = PaddingMode.Zeros;
    // or ... aes.Padding = PaddingMode.None;
    var decryptor = aes.CreateDecryptor(key.ToArray(), iv.ToArray());
    var decryptedString = string.Empty;

    using (var memoryStream = new MemoryStream(encryptedBytes))
    {
        using (var cryptoStream = new CryptoStream(memoryStream, decryptor, CryptoStreamMode.Read))
        {
            using (var reader = new StreamReader(cryptoStream))
            {
                decryptedString = reader.ReadToEnd();
            }
        }
    }

    return result;
}

How can the issue with the padding be explained? Just before encryption the Go program checks the padding:

// CBC mode always works in whole blocks.
if len(secretBytesDecrypted)%aes.BlockSize != 0 {
    numberNecessaryBlocks := int(math.Ceil(float64(len(secretBytesDecrypted)) / float64(aes.BlockSize)))
    enhanced := make([]byte, numberNecessaryBlocks*aes.BlockSize)
    copy(enhanced, secretBytesDecrypted)
    secretBytesDecrypted = enhanced
}

The important part is this:

enhanced := make([]byte, numberNecessaryBlocks*aes.BlockSize)
copy(enhanced, secretBytesDecrypted)

A new array is created with an appropriate length, so that the length is a multiple of the block size. This new array is filled with zeros. The copy method then copies the existing data into it. It is ensured that the new array is larger than the existing data. Accordingly, there are zeros at the end of the array.

Thus, the C# code can use PaddingMode.Zeros. The alternative PaddingMode.None just ignores any padding, which also works. I hope this answer is helpful for anyone who has to port code from Go to C#, etc.

For completeness: In the current version of chrome, the setting is no longer at the bottom but can be found when clicking the "Filter" icon at the top of the console tab (second icon from the left)

I suggest that you don't do this, initially. Instead, start a new emacs session and test whatever changes you made to see if they work correctly. The reason to do it this way is to avoid leaving you in a state where you have an inoperable .emacs file, which fails to load or fails to load cleanly. If you do all of your editing in the original session, and all of your testing in a new session, you'll always have something reliable to comment out offending code.

When you are finally happy with your changes, then go ahead and use one of the other answers to re-load. My personal preference is to eval just the section you've added/changed, and to do that just highlight the region of added/changed code and call M-x eval-region. Doing that minimizes the code that's evaluated, minimizing any unintentional side-effects, as luapyad points out.

    /// <summary>
    /// Combine two Arrays with offset and count
    /// </summary>
    /// <param name="src1"></param>
    /// <param name="offset1"></param>
    /// <param name="count1"></param>
    /// <param name="src2"></param>
    /// <param name="offset2"></param>
    /// <param name="count2"></param>
    /// <returns></returns>
    public static T[] Combine<T>(this T[] src1, int offset1, int count1, T[] src2, int offset2, int count2) 
        => Enumerable.Range(0, count1 + count2).Select(a => (a < count1) ? src1[offset1 + a] : src2[offset2 + a - count1]).ToArray();

This could be as simple as a template conflict. Revert to default template in System/Configuration/Design/Themes.

No refresh is needed if the "val"-parameter is used for setting the value, see fiddle. Use brackets for the value to enable multiple selected values.

$('.selectpicker').selectpicker('val', [1]); 

You can create .war file back from your existing folder.

Using this command

cd /to/your/folder/location
jar -cvf my_web_app.war *

You can execute shell script in two ways,either by using cron job or by writing a shell script

Lets assume your script name is "yourscript.sh"

First check the user permission of the script. use below command to check user permission of the script

ll script.sh

If the script is in root,then use below command

sudo crontab -e

Second if the script holds the user "ubuntu", then use below command

crontab -e

Add the following line in your crontab:-

55 23 * * * /path/to/yourscript.sh

Another way of doing this is to write a script and run it in the backgroud

Here is the script where you have to put your script name(eg:- youscript.sh) which is going to run at 23:55pm everyday

#!/bin/bash while true do /home/modassir/yourscript.sh sleep 1d done

save it in a file (lets name it "every-day.sh")

sleep 1d - means it waits for one day and then it runs again.

now give the permission to your script.use below command:-

chmod +x every-day.sh

now, execute this shell script in the background by using "nohup". This will keep executing the script even after you logout from your session.

use below command to execute the script.

nohup ./every-day.sh &

Note:- to run "yourscript.sh" at 23:55pm everyday,you have to execute "every-day.sh" script at exactly 23:55pm.

TL;DR:

No, don't subscribe manually to them, don't use them in services. Use them as is shown in the documentation only to emit events in components. Don't defeat angular's abstraction.

Answer:

No, you should not subscribe manually to it.

EventEmitter is an angular2 abstraction and its only purpose is to emit events in components. Quoting a comment from Rob Wormald

[...] EventEmitter is really an Angular abstraction, and should be used pretty much only for emitting custom Events in components. Otherwise, just use Rx as if it was any other library.

This is stated really clear in EventEmitter's documentation.

Use by directives and components to emit custom Events.

What's wrong about using it?

Angular2 will never guarantee us that EventEmitter will continue being an Observable. So that means refactoring our code if it changes. The only API we must access is its emit() method. We should never subscribe manually to an EventEmitter.

All the stated above is more clear in this Ward Bell's comment (recommended to read the article, and the answer to that comment). Quoting for reference

Do NOT count on EventEmitter continuing to be an Observable!

Do NOT count on those Observable operators being there in the future!

These will be deprecated soon and probably removed before release.

Use EventEmitter only for event binding between a child and parent component. Do not subscribe to it. Do not call any of those methods. Only call eve.emit()

His comment is in line with Rob's comment long time ago.

So, how to use it properly?

Simply use it to emit events from your component. Take a look a the following example.

@Component({
    selector : 'child',
    template : `
        <button (click)="sendNotification()">Notify my parent!</button>
    `
})
class Child {
    @Output() notifyParent: EventEmitter<any> = new EventEmitter();
    sendNotification() {
        this.notifyParent.emit('Some value to send to the parent');
    }
}

@Component({
    selector : 'parent',
    template : `
        <child (notifyParent)="getNotification($event)"></child>
    `
})
class Parent {
    getNotification(evt) {
        // Do something with the notification (evt) sent by the child!
    }
}

How not to use it?

class MyService {
    @Output() myServiceEvent : EventEmitter<any> = new EventEmitter();
}

Stop right there... you're already wrong...

Hopefully these two simple examples will clarify EventEmitter's proper usage.

If you want nice json without hardcoding attributes into your service classes,

use <webHttp defaultOutgoingResponseFormat="Json"/> in your behavior config

Great gugly muglys! This was harder than it needed to be.

Export one flat default

This is a great opportunity to use spread (... in { ...Matters, ...Contacts } below:

// imports/collections/Matters.js
export default {           // default export
  hello: 'World',
  something: 'important',
};

// imports/collections/Contacts.js
export default {           // default export
  hello: 'Moon',
  email: '[email protected]',
};

// imports/collections/index.js
import Matters from './Matters';      // import default export as var 'Matters'
import Contacts from './Contacts';

export default {  // default export
  ...Matters,     // spread Matters, overwriting previous properties
  ...Contacts,    // spread Contacts, overwriting previosu properties
};

// imports/test.js
import collections from './collections';  // import default export as 'collections'

console.log(collections);

Then, to run babel compiled code from the command line (from project root /):

$ npm install --save-dev @babel/core @babel/cli @babel/preset-env @babel/node 
(trimmed)

$ npx babel-node --presets @babel/preset-env imports/test.js 
{ hello: 'Moon',
  something: 'important',
  email: '[email protected]' }

Export one tree-like default

If you'd prefer to not overwrite properties, change:

// imports/collections/index.js
import Matters from './Matters';     // import default as 'Matters'
import Contacts from './Contacts';

export default {   // export default
  Matters,
  Contacts,
};

And the output will be:

$ npx babel-node --presets @babel/preset-env imports/test.js
{ Matters: { hello: 'World', something: 'important' },
  Contacts: { hello: 'Moon', email: '[email protected]' } }

Export multiple named exports w/ no default

If you're dedicated to DRY, the syntax on the imports changes as well:

// imports/collections/index.js

// export default as named export 'Matters'
export { default as Matters } from './Matters';  
export { default as Contacts } from './Contacts'; 

This creates 2 named exports w/ no default export. Then change:

// imports/test.js
import { Matters, Contacts } from './collections';

console.log(Matters, Contacts);

And the output:

$ npx babel-node --presets @babel/preset-env imports/test.js
{ hello: 'World', something: 'important' } { hello: 'Moon', email: '[email protected]' }

Import all named exports

// imports/collections/index.js

// export default as named export 'Matters'
export { default as Matters } from './Matters';
export { default as Contacts } from './Contacts';

// imports/test.js

// Import all named exports as 'collections'
import * as collections from './collections';

console.log(collections);  // interesting output
console.log(collections.Matters, collections.Contacts);

Notice the destructuring import { Matters, Contacts } from './collections'; in the previous example.

$ npx babel-node --presets @babel/preset-env imports/test.js
{ Matters: [Getter], Contacts: [Getter] }
{ hello: 'World', something: 'important' } { hello: 'Moon', email: '[email protected]' }

In practice

Given these source files:

/myLib/thingA.js
/myLib/thingB.js
/myLib/thingC.js

Creating a /myLib/index.js to bundle up all the files defeats the purpose of import/export. It would be easier to make everything global in the first place, than to make everything global via import/export via index.js "wrapper files".

If you want a particular file, import thingA from './myLib/thingA'; in your own projects.

Creating a "wrapper file" with exports for the module only makes sense if you're packaging for npm or on a multi-year multi-team project.

Made it this far? See the docs for more details.

Also, yay for Stackoverflow finally supporting three `s as code fence markup.

I have the same problem. I avoid it with remove.packages("Package making this confusion") and it works. In my case, I don't need the second package, so that is not a very good idea.

String jsonErrorString=((HttpClientErrorException)exception).getResponseBodyAsString();
JSONObject jsonObj=null;
String errorDetails=null;
String status=null;
try {
        jsonObj = new JSONObject(jsonErrorString);
        int index =jsonObj.getString("detail").indexOf(":");
                errorDetails=jsonObj.getString("detail").substring(index);
                status=jsonObj.getString("status");

            } catch (JSONException e) {
                // TODO Auto-generated catch block
                e.printStackTrace();
            }
            item.put("status", status);
            item.put("errordetailMsg", errorDetails);

I built an extension called Checkpoints, an alternative to Local History. Checkpoints has support for viewing history for all files (that has checkpoints) in the tree view, not just the currently active file. There are some other minor differences aswell, but overall they are pretty similar.

How about using the history replacement function to add the site into the browsers history?

Try executing the following as soon as the window loads-

history.replaceState("example", "title", "http://www.example.com");

This should hopefully make it so even if it is the first page they have accessed, the URL you define in the code will be what they're taken to when they click back.

I've just done this for a project, and achieved it by using the h6 tag which I wasn't using for anything else:

in html code:

<h6><img alt="small drawing" src="../Images/image1.jpg" width="50%"/> <img alt="small drawing" src="../Images/image2.jpg" width="50%"/><br/>Optional caption text</h6>

The space between the image tags puts a vertical gap between the images. The width argument in each img tag is optional, but it neatly sizes the images to fill the width of the page. Notice that each image must be set to take up only 50% of the width. (Or 33% if you're using 3 images.) The width argument must come after the alt and src arguments or it won't work.

in css code:

/* h6: set presentation of images */
h6
  {
  font-family: "Franklin Gothic Demi", serif;
  font-size: 1.0em;
  font-weight: normal;
  line-height: 1.25em;
  text-align: center;
  }

The text items set the look of the caption text, and the text-align property centers both the images and the caption text.

Certainly, how it's done depends on your shell. In Bash, you can use single quotes around the message and can just leave the quote open, which will make Bash prompt for another line, until you close the quote. Like this:

git commit -m 'Message

goes
here'

Alternatively, you can use a "here document" (also known as heredoc):

git commit -F- <<EOF
Message

goes
here
EOF

Latest published version of the Support Library is 24.1.1, So you can use it like this,

compile 'com.android.support:appcompat-v7:24.1.1'
compile 'com.android.support:design:24.1.1'

Same as for other support components.

You can see the revisions here,
https://developer.android.com/topic/libraries/support-library/revisions.html

public string MakeRelativePath(string workingDirectory, string fullPath)
{
    string result = string.Empty;
    int offset;

    // this is the easy case.  The file is inside of the working directory.
    if( fullPath.StartsWith(workingDirectory) )
    {
        return fullPath.Substring(workingDirectory.Length + 1);
    }

    // the hard case has to back out of the working directory
    string[] baseDirs = workingDirectory.Split(new char[] { ':', '\\', '/' });
    string[] fileDirs = fullPath.Split(new char[] { ':', '\\', '/' });

    // if we failed to split (empty strings?) or the drive letter does not match
    if( baseDirs.Length <= 0 || fileDirs.Length <= 0 || baseDirs[0] != fileDirs[0] )
    {
        // can't create a relative path between separate harddrives/partitions.
        return fullPath;
    }

    // skip all leading directories that match
    for (offset = 1; offset < baseDirs.Length; offset++)
    {
        if (baseDirs[offset] != fileDirs[offset])
            break;
    }

    // back out of the working directory
    for (int i = 0; i < (baseDirs.Length - offset); i++)
    {
        result += "..\\";
    }

    // step into the file path
    for (int i = offset; i < fileDirs.Length-1; i++)
    {
        result += fileDirs[i] + "\\";
    }

    // append the file
    result += fileDirs[fileDirs.Length - 1];

    return result;
}

This code is probably not bullet-proof but this is what I came up with. It's a little more robust. It takes two paths and returns path B as relative to path A.

example:

MakeRelativePath("c:\\dev\\foo\\bar", "c:\\dev\\junk\\readme.txt")
//returns: "..\\..\\junk\\readme.txt"

MakeRelativePath("c:\\dev\\foo\\bar", "c:\\dev\\foo\\bar\\docs\\readme.txt")
//returns: "docs\\readme.txt"

It's an old post, but if anyone is still looking for solution to this kind of problem, here is what I came up with:

<script>
  document.addEventListener("DOMContentLoaded", function(e) {
    document.forms['AddAndEdit'].elements['list'].value = 11;
  });
</script>

I had the same exact problem and found the solution through the use of larachat.

Here's how to fix it you need to have your homestead.yaml file settings correct. If you want to know how its done follow Jeffery Way tutorial on homestead 2.0 https://laracasts.com/lessons/say-hello-to-laravel-homestead-two.

Now to fix Input not specified issue you need to ssh into homestead box and type

serve domain.app /home/vagrant/Code/path/to/public/directory this will generate a serve script for nginx. You will need to do this everytime you switch projects.

He also discussed what I explained in this series https://laracasts.com/series/laravel-5-fundamentals/

reserve when you do not want the objects to be initialized when reserved. also, you may prefer to logically differentiate and track its count versus its use count when you resize. so there is a behavioral difference in the interface - the vector will represent the same number of elements when reserved, and will be 100 elements larger when resized in your scenario.

Is there any better choice in this kind of scenario?

it depends entirely on your aims when fighting the default behavior. some people will favor customized allocators -- but we really need a better idea of what it is you are attempting to solve in your program to advise you well.

fwiw, many vector implementations will simply double the allocated element count when they must grow - are you trying to minimize peak allocation sizes or are you trying to reserve enough space for some lock free program or something else?

A SHA1 hash is 40 chars long!

import java.util.*;
public class BinaryToDecimal
{
  public static void main()
  {
    Scanner sc=new Scanner(System.in);
    System.out.println("enter the binary number");
    double s=sc.nextDouble();
    int c=0;
    long s1=0;
    while(s>0)
    {
        s1=s1+(long)(Math.pow(2,c)*(long)(s%10));
        s=(long)s/10;
        c++;
    }
    System.out.println("The respective decimal number is : "+s1);
  }
}

You can use multiple font faces quite easily. Below is an example of how I used it in the past:

<!--[if (IE)]><!-->
    <style type="text/css" media="screen">
        @font-face {
            font-family: "Century Schoolbook";
            src: url(/fonts/century-schoolbook.eot);
        }

It is worth noting that fonts can be funny across different Browsers. Font face on earlier browsers works, but you need to use eot files instead of ttf.

That is why I include my fonts in the head of the html file as I can then use conditional IE tags to use eot or ttf files accordingly.

If you need to convert ttf to eot for this purpose there is a brilliant website you can do this for free online, which can be found at http://ttf2eot.sebastiankippe.com/.

Hope that helps.

If someone can show me an example of something that can be done with an IntentService and can not be done with a Service and the other way around.

By definition, that is impossible. IntentService is a subclass of Service, written in Java. Hence, anything an IntentService does, a Service could do, by including the relevant bits of code that IntentService uses.

Starting a service with its own thread is like starting an IntentService. Is it not?

The three primary features of an IntentService are:

• the background thread

• the automatic queuing of Intents delivered to onStartCommand(), so if one Intent is being processed by onHandleIntent() on the background thread, other commands queue up waiting their turn

• the automatic shutdown of the IntentService, via a call to stopSelf(), once the queue is empty

Any and all of that could be implemented by a Service without extending IntentService.

This issue can be caused by the libxml entity loader having been disabled.

Try running libxml_disable_entity_loader(false); before instantiating SoapClient.

To find the folder location, you can just run the app, open the task manager (CTRL-SHIFT-ESC), select the app and right-click|Open file location.

My suggestion would be a combination of implement a few of them and analyze some implementations of them. For example, within .Net, there are uses of adapter patterns if you look at Data Adapters, as well as a few others if one does a little digging into the framework.

Turns out this has nothing to do with CORS- it was a problem with the security certificate. Misleading errors = 4 hours of headaches.

The heap is the place in memory where your dynamically allocated objects live. If you used new then it's on the heap. That's as opposed to stack space, which is where the function stack lives. If you have a local variable then that reference is on the stack. Java's heap is subject to garbage collection and the objects are usable directly.

EHCache's off-heap storage takes your regular object off the heap, serializes it, and stores it as bytes in a chunk of memory that EHCache manages. It's like storing it to disk but it's still in RAM. The objects are not directly usable in this state, they have to be deserialized first. Also not subject to garbage collection.

I had the same problem and figured it out from your comments, but thought I would add the reason I caused the error to occur (for other beginners).

I had opened and edited .bash_profile using the open command in Terminal, which opened it in Text Editor. I typed in an addition to .bash_profile and it used improper quote characters. I opened .bash_profile in Atom and fixed up the error. I also associated the file with Atom for future editing.

In Go, you can multiply variables of same type, so you need to have both parts of the expression the same type.

The simplest thing you can do is casting an integer to duration before multiplying, but that would violate unit semantics. What would be multiplication of duration by duration in term of units?

I'd rather convert time.Millisecond to an int64, and then multiply it by the number of milliseconds, then cast to time.Duration:

time.Duration(int64(time.Millisecond) * int64(rand.Int31n(1000)))

This way any part of the expression can be said to have a meaningful value according to its type. int64(time.Millisecond) part is just a dimensionless value - the number of smallest units of time in the original value.

If walk a slightly simpler path:

time.Duration(rand.Int31n(1000)) * time.Millisecond

The left part of multiplication is nonsense - a value of type "time.Duration", holding something irrelevant to its type:

numberOfMilliseconds := 100
// just can't come up with a name for following:
someLHS := time.Duration(numberOfMilliseconds)
fmt.Println(someLHS)
fmt.Println(someLHS*time.Millisecond)

And it's not just semantics, there is actual functionality associated with types. This code prints:

100ns
100ms

Interestingly, the code sample here uses the simplest code, with the same misleading semantics of Duration conversion: https://golang.org/pkg/time/#Duration

seconds := 10

fmt.Print(time.Duration(seconds)*time.Second) // prints 10s

As far as I know, Git doesn't track folders, only files - so empty folders (or folders where all files are ignored) cannot be committed. If you e.g. need the folder to be present due to some step in your build process, perhaps you can have your build tool create it instead? Or you could put one empty, unignored file in the folder and commit it.

you should use escape character like this:

printf("\"");

While both reducebykey and groupbykey will produce the same answer, the reduceByKey example works much better on a large dataset. That's because Spark knows it can combine output with a common key on each partition before shuffling the data.

On the other hand, when calling groupByKey - all the key-value pairs are shuffled around. This is a lot of unnessary data to being transferred over the network.

for more detailed check this below link

As of this writing I believe this can be accomplished with the IClaimsTransformation interface in asp.net core 2 and above. I just implemented a proof of concept which is sharable enough to post here.

public class PrivilegesToClaimsTransformer : IClaimsTransformation
{
    private readonly IPrivilegeProvider privilegeProvider;
    public const string DidItClaim = "http://foo.bar/privileges/resolved";

    public PrivilegesToClaimsTransformer(IPrivilegeProvider privilegeProvider)
    {
        this.privilegeProvider = privilegeProvider;
    }

    public async Task<ClaimsPrincipal> TransformAsync(ClaimsPrincipal principal)
    {
        if (principal.Identity is ClaimsIdentity claimer)
        {
            if (claimer.HasClaim(DidItClaim, bool.TrueString))
            {
                return principal;
            }

            var privileges = await this.privilegeProvider.GetPrivileges( ... );
            claimer.AddClaim(new Claim(DidItClaim, bool.TrueString));

            foreach (var privilegeAsRole in privileges)
            {
                claimer.AddClaim(new Claim(ClaimTypes.Role /*"http://schemas.microsoft.com/ws/2008/06/identity/claims/role" */, privilegeAsRole));
            }
        }

        return principal;
    }
}

To use this in your Controller just add an appropriate [Authorize(Roles="whatever")] to your methods.

[HttpGet]
[Route("poc")]
[Authorize(Roles = "plugh,blast")]
public JsonResult PocAuthorization()
{
    var result = Json(new
    {
        when = DateTime.UtcNow,
    });

    result.StatusCode = (int)HttpStatusCode.OK;

    return result;
}

In our case every request includes an Authorization header that is a JWT. This is the prototype and I believe we will do something super close to this in our production system next week.

Future voters, consider the date of writing when you vote. As of today, this works on my machine.™ You will probably want more error handling and logging on your implementation.

I tested for JS with Node 4.0.0 if anyone is interested. Declaring outside the loop resulted in a ~.5 ms performance improvement on average over 1000 trials with 100 million loop iterations per trial. So I'm gonna say go ahead and write it in the most readable / maintainable way which is B, imo. I would put my code in a fiddle, but I used the performance-now Node module. Here's the code:

var now = require("../node_modules/performance-now")

// declare vars inside loop
function varInside(){
    for(var i = 0; i < 100000000; i++){
        var temp = i;
        var temp2 = i + 1;
        var temp3 = i + 2;
    }
}

// declare vars outside loop
function varOutside(){
    var temp;
    var temp2;
    var temp3;
    for(var i = 0; i < 100000000; i++){
        temp = i
        temp2 = i + 1
        temp3 = i + 2
    }
}

// for computing average execution times
var insideAvg = 0;
var outsideAvg = 0;

// run varInside a million times and average execution times
for(var i = 0; i < 1000; i++){
    var start = now()
    varInside()
    var end = now()
    insideAvg = (insideAvg + (end-start)) / 2
}

// run varOutside a million times and average execution times
for(var i = 0; i < 1000; i++){
    var start = now()
    varOutside()
    var end = now()
    outsideAvg = (outsideAvg + (end-start)) / 2
}

console.log('declared inside loop', insideAvg)
console.log('declared outside loop', outsideAvg)

Another simple solution to digest an array elements once:

while(Auction.auctions.length){
    // From first to last...
    var auction = Auction.auctions.shift();
    // From last to first...
    var auction = Auction.auctions.pop();

    // Do stuff with auction
}

Another veneration of find_elements_by_xpath(".//*") is:

from selenium.webdriver.common.by import By


find_elements(By.XPATH, ".//*")

My solution: https://gist.github.com/pangui/86b5e0610b53ddf28f94 It prevents double click but accepts more clicks after 1 second. Hope it helps.

Here is the code:

jQuery.fn.preventDoubleClick = function() {
  $(this).on('click', function(e){
    var $el = $(this);
    if($el.data('clicked')){
      // Previously clicked, stop actions
      e.preventDefault();
      e.stopPropagation();
    }else{
      // Mark to ignore next click
      $el.data('clicked', true);
      // Unmark after 1 second
      window.setTimeout(function(){
        $el.removeData('clicked');
      }, 1000)
    }
  });
  return this;
}; 

import datetime

a = '2010-01-31'

datee = datetime.datetime.strptime(a, "%Y-%m-%d")


datee.month
Out[9]: 1

datee.year
Out[10]: 2010

datee.day
Out[11]: 31

You can use .indexOf():

if(str.indexOf(substr) > -1) {

}

public static final List<String> permissions = new ArrayList<String>() {{
    add("public_profile");
    add("email");
    add("user_birthday");
    add("user_about_me");
    add("user_location");
    add("user_likes");
    add("user_posts");
}};

I've found one difference between the two constructions that bit me pretty hard.

Let's say I have:

function MyClass(){
  this.property1=[];
  this.property2=new Array();
};
var MyObject1=new MyClass();
var MyObject2=new MyClass();

In real life, if I do this:

MyObject1.property1.push('a');
MyObject1.property2.push('b');
MyObject2.property1.push('c');
MyObject2.property2.push('d');

What I end up with is this:

MyObject1.property1=['a','c']
MyObject1.property2=['b']
MyObject2.property1=['a','c']
MyObject2.property2=['d']

I don't know what the language specification says is supposed to happen, but if I want my two objects to have unique property arrays in my objects, I have to use new Array().

Its very simple actually. Try this:

str1="a    b     c      d"
splitStr1 = str1.split()
print splitStr1

Should also be able to do this:

total += eval(myInt1) + eval(myInt2) + eval(myInt3);

This helped me in a different, but similar, situation.

Hadley has a very elegant solution to do this inside data frames in his reshape package, using the function colsplit.

require(reshape)
> df <- data.frame(ID=11:13, FOO=c('a|b','b|c','x|y'))
> df
  ID FOO
1 11 a|b
2 12 b|c
3 13 x|y
> df = transform(df, FOO = colsplit(FOO, split = "\\|", names = c('a', 'b')))
> df
  ID FOO.a FOO.b
1 11     a     b
2 12     b     c
3 13     x     y

Another simple solution that hasn't been suggested yet would be to use xargs:

ls *.avi | xargs -i -n1 ffmpeg -i {} "{}.mp4"

One minor pitfall is the awkward naming of output files (e.g. input.avi.mp4). A possible workaround for this might be:

ls *.avi | xargs -i -n1 bash -c "i={}; ffmpeg -i {} "\${i%.*}.mp4""

You can use filter. This method always returns the element if the condition is true. So if you want to remove by id you must keep all the element that doesn't match with the given id. Here is an example:

arrayOfObjects = arrayOfObjects.filter(obj => obj.id != idToRemove)

For Linux to reset current 30 days expiration license, you must run code:

rm ~/.config/JetBrains/IntelliJIdea2019.3/options/other.xml
rm -rf ~/.config/JetBrains/IntelliJIdea2019.3/eval/*
rm -rf .java/.userPrefs

Change your code to

document.write("<td width='74'><button id='button' type='button' onclick='myfunction(\""+ name + "\")'>click</button></td>")

here's another alternative using vector::assign:

theVector.assign(theSet.begin(), theSet.end());

Android Studio:

• "File" > "Settings" and type "MissingTranslation" into the search box

Eclipse:

• Windows/Linux: In "Window" > "Preferences" > "Android" > "Lint Error Checking"
• Mac: "Eclipse" > "Preferences" > "Android" > "Lint Error Checking"

Find the MissingTranslation line, and set it to Warning as seen below:

One liner:
for file in *.php ; do mv "$file" "_$file" ; done

It works, this is a problem with the tool used: normalized CSS by jsFiddle is causing the problem by hiding you the default of browsers...
See http://jsfiddle.net/XvdX9/5/

EDIT:
normalize.css stylesheet from jsFiddle adds the instruction border-collapse: collapse to all tables and it renders them completely differently in CSS2.1:

• The separated borders model
• The collapsing border model

Differences between the 2 models can be seen in this other fiddle: http://jsfiddle.net/XvdX9/11/ (with some transparencies on cells and an enormous border-radius on the top-left one, in order to see what happens on table vs its cells)

In the same CSS2.1 page about HTML tables, there are also explanations about what browsers should/could do with empty-cells in the separated borders model, the difference between border-style: none and border-style: hidden in the collapsing borders model, how width is calculated and which border should display if both table, row and cell elements define 3 different styles on the same border.

Can also do it this way but other ways seem better, this comes in handy if you only need it the once.

onkeyup="this.value = this.value.toUpperCase();"

Since Java 7 this is very easy and intuitive to do.

List<String> fileContent = new ArrayList<>(Files.readAllLines(FILE_PATH, StandardCharsets.UTF_8));

for (int i = 0; i < fileContent.size(); i++) {
    if (fileContent.get(i).equals("old line")) {
        fileContent.set(i, "new line");
        break;
    }
}

Files.write(FILE_PATH, fileContent, StandardCharsets.UTF_8);

Basically you read the whole file to a List, edit the list and finally write the list back to file.

FILE_PATH represents the Path of the file.

View -> Error list -> Right click on specific Error/Warning.

You can change Severity as You want.

As you will already be aware, multiple inheritance of classes in Java is not possible, but it's possible with interfaces. You may also want to consider using the composition design pattern.

I wrote a very comprehensive article on composition a few years ago...

Working with dplyr

library(dplyr)

df <- data.frame(A = factor(LETTERS[1:5]),
                 B = 1:5, C = as.logical(c(1, 1, 0, 0, 1)),
                 D = letters[1:5],
                 E = paste(LETTERS[1:5], letters[1:5]),
                 stringsAsFactors = FALSE)

str(df)

we get:

'data.frame':   5 obs. of  5 variables:
 $ A: Factor w/ 5 levels "A","B","C","D",..: 1 2 3 4 5
 $ B: int  1 2 3 4 5
 $ C: logi  TRUE TRUE FALSE FALSE TRUE
 $ D: chr  "a" "b" "c" "d" ...
 $ E: chr  "A a" "B b" "C c" "D d" ...

Now, we can convert all chr to factors:

df <- df%>%mutate_if(is.character, as.factor)
str(df)

And we get:

'data.frame':   5 obs. of  5 variables:
 $ A: Factor w/ 5 levels "A","B","C","D",..: 1 2 3 4 5
 $ B: int  1 2 3 4 5
 $ C: logi  TRUE TRUE FALSE FALSE TRUE
 $ D: chr  "a" "b" "c" "d" ...
 $ E: chr  "A a" "B b" "C c" "D d" ...

Let's provide also other solutions:

With base package:

df[sapply(df, is.character)] <- lapply(df[sapply(df, is.character)], 
                                                           as.factor)

With dplyr 1.0.0

df <- df%>%mutate(across(where(is.factor), as.character))

With purrr package:

library(purrr)

df <- df%>% modify_if(is.factor, as.character) 

If your time is in a variable called t

int hours = t / 60; //since both are ints, you get an int
int minutes = t % 60;
System.out.printf("%d:%02d", hours, minutes);

It couldn't get easier

I know this topic is old, but it ranks very well in Google. I found out that putting this in your header works well;

<meta Http-Equiv="Cache-Control" Content="no-cache">
<meta Http-Equiv="Pragma" Content="no-cache">
<meta Http-Equiv="Expires" Content="0">
<meta Http-Equiv="Pragma-directive: no-cache">
<meta Http-Equiv="Cache-directive: no-cache">

I also recommend pt versus cm or mm as it's more precise. Also, I cannot get @page to work in Chrome (version 30.0.1599.69 m) It ignores anything I put for the margins, large or small. But, you can get it to work with body margins on the document, weird.

No

Only if the other application is designed to allow it, by providing components for you to add into your own application.

Try this:

jQuery(document).ready(function(){
   $("#special").click(function(e){
      $('#status2').html(e.pageX +', '+ e.pageY);
   }); 
})

Here you can find more info with DEMO

If your function is expecting to return a boolean, just do this:

1. Import:

import { of, Observable } from 'rxjs';
import { map, catchError } from 'rxjs/operators';

2. Then

checkLogin(): Observable<boolean> {
  return this.service.getData()
    .pipe(
      map(response => {
        this.data = response;
        this.checkservice = true;
        return true;
      }),
      catchError(error => {
        this.router.navigate(['newpage']);
        console.log(error);
        return of(false);
      })
)}

Open the terminal in ubuntu (ctrl+shift+t)
sudo gedit /etc/tomcat7/server.xml

change the default port in the server.xml,from 8080 to anything like 8081,8181,8008. Then save the file .

Now the project will work nicely without any interruption.

I think that C++.

Because c# needs additional instalation for C# runtime which only absorbs space on a disk. And C# is of course a bit slower.

 "foobar".gsub(/(o+)/){|s|s+'ball'}
 #=> "fooballbar"

               /* Didn't test it but this should work "out of the box" */

                AlertDialog.Builder builder = new AlertDialog.Builder(this);
                //you should edit this to fit your needs
                builder.setTitle("Double Edit Text");

                final EditText one = new EditText(this);
                from.setHint("one");//optional
                final EditText two = new EditText(this);
                to.setHint("two");//optional

                //in my example i use TYPE_CLASS_NUMBER for input only numbers
                from.setInputType(InputType.TYPE_CLASS_NUMBER);
                to.setInputType(InputType.TYPE_CLASS_NUMBER);

                LinearLayout lay = new LinearLayout(this);

                lay.addView(two);
                builder.setView(lay);

                // Set up the buttons
                builder.setPositiveButton("Ok", new DialogInterface.OnClickListener() {
                  public void onClick(DialogInterface dialog, int whichButton) {
                       //get the two inputs
                       int i = Integer.parseInt(one.getText().toString());
                       int j = Integer.parseInt(two.getText().toString());
                  }
                });

                builder.setNegativeButton("Cancel", new DialogInterface.OnClickListener() {
                  public void onClick(DialogInterface dialog, int whichButton) {
                       dialog.cancel();
                }
              });
              builder.show();

Here's what I would do to get what you want :

$(document).ready(function() {
    $(".testform").click(function(event) {
        if( !confirm('Are you sure that you want to submit the form') ) 
            event.preventDefault();
    });
});

A slight explanation about how that code works, When the user clicks the button then the confirm dialog is launched, in case the user selects no the default action which was to submit the form is not carried out. Upon confirmation the control is passed to the browser which carries on with submitting the form. We use the standard JavaScript confirm here.

Here's making the indexes unusable without the file:

DECLARE
  CURSOR  usr_idxs IS select * from user_indexes;
  cur_idx  usr_idxs% ROWTYPE;
  v_sql  VARCHAR2(1024);

BEGIN
  OPEN usr_idxs;
  LOOP
    FETCH usr_idxs INTO cur_idx;
    EXIT WHEN NOT usr_idxs%FOUND;

    v_sql:= 'ALTER INDEX ' || cur_idx.index_name || ' UNUSABLE';
    EXECUTE IMMEDIATE v_sql;
  END LOOP;
  CLOSE usr_idxs;
END;

The rebuild would be similiar.

i did this and this returned the number of files in the folder(Attack_Data)...this works fine.

import os
def fcount(path):
    #Counts the number of files in a directory
    count = 0
    for f in os.listdir(path):
        if os.path.isfile(os.path.join(path, f)):
            count += 1

    return count
path = r"C:\Users\EE EKORO\Desktop\Attack_Data" #Read files in folder
print (fcount(path))

Yes, I couldn't see how to use 'default' in the migration generator command either but was able to specify a default value for a new string column as follows by amending the generated migration file before applying "rake db:migrate":

class AddColumnToWidgets < ActiveRecord::Migration
  def change
    add_column :widgets, :colour, :string, default: 'red'
  end
end

This adds a new column called 'colour' to my 'Widget' model and sets the default 'colour' of new widgets to 'red'.

It's not in standard C, so the behavior is undefined.

Some implementation uses it to clear stdin buffer.

From C11 7.21.5.2 The fflush function, fflush works only with output/update stream, not input stream.

If stream points to an output stream or an update stream in which the most recent operation was not input, the fflush function causes any unwritten data for that stream to be delivered to the host environment to be written to the file; otherwise, the behavior is undefined.

One thing that I have to add is that there is no reference in C.

Secondly, this is the language syntax convention. & - is an address operator but it also mean a reference - all depends on usa case

If there was some "reference" keyword instead of & you could write

int CDummy::isitme (reference CDummy param)

but this is C++ and we should accept it advantages and disadvantages...

Use Maths. If the two operations mathematically depend on the loop iteration, why not do the math?

int i, j;//That have some meaningful values in them?
for( int counter = 0; counter < count_max; ++counter )
    do_something (counter+i, counter+j);

Or, more specifically referring to the OP's example:

for(int i = 0; i != 5; ++i)
    do_something(i, j+i);

Especially if you're passing into a function by value, then you should get something that does exactly what you want.

I got the same error (TypeError: 'int' object is not callable)

def xlim(i,k,s1,s2):
   x=i/(2*k)
   xl=x*(1-s2*x-s1*(1-x)) / (1-s2*x**2-2*s1*x(1-x))
   return xl 
... ... ... ... 

>>> xlim(1,100,0,0)
Traceback (most recent call last):

after reading this post I realized that I forgot a multiplication sign * so

def xlim(i,k,s1,s2):
   x=i/(2*k)
   xl=x*(1-s2*x-s1*(1-x)) / (1-s2*x**2-2*s1*x * (1-x))
   return xl 

xlim(1.0,100.0,0.0,0.0)

When would you use private and when would you use protected?

Private Inheritance can be thought of Implemented in terms of relationship rather than a IS-A relationship. Simply put, the external interface of the inheriting class has no (visible) relationship to the inherited class, It uses the private inheritance only to implement a similar functionality which the Base class provides.

Unlike, Private Inheritance, Protected inheritance is a restricted form of Inheritance,wherein the deriving class IS-A kind of the Base class and it wants to restrict the access of the derived members only to the derived class.

Isolation level defines how the changes made to some data repository by one transaction affect other simultaneous concurrent transactions, and also how and when that changed data becomes available to other transactions. When we define a transaction using the Spring framework we are also able to configure in which isolation level that same transaction will be executed.

@Transactional(isolation=Isolation.READ_COMMITTED)
public void someTransactionalMethod(Object obj) {

}

READ_UNCOMMITTED isolation level states that a transaction may read data that is still uncommitted by other transactions.

READ_COMMITTED isolation level states that a transaction can't read data that is not yet committed by other transactions.

REPEATABLE_READ isolation level states that if a transaction reads one record from the database multiple times the result of all those reading operations must always be the same.

SERIALIZABLE isolation level is the most restrictive of all isolation levels. Transactions are executed with locking at all levels (read, range and write locking) so they appear as if they were executed in a serialized way.

Propagation is the ability to decide how the business methods should be encapsulated in both logical or physical transactions.

Spring REQUIRED behavior means that the same transaction will be used if there is an already opened transaction in the current bean method execution context.

REQUIRES_NEW behavior means that a new physical transaction will always be created by the container.

The NESTED behavior makes nested Spring transactions to use the same physical transaction but sets savepoints between nested invocations so inner transactions may also rollback independently of outer transactions.

The MANDATORY behavior states that an existing opened transaction must already exist. If not an exception will be thrown by the container.

The NEVER behavior states that an existing opened transaction must not already exist. If a transaction exists an exception will be thrown by the container.

The NOT_SUPPORTED behavior will execute outside of the scope of any transaction. If an opened transaction already exists it will be paused.

The SUPPORTS behavior will execute in the scope of a transaction if an opened transaction already exists. If there isn't an already opened transaction the method will execute anyway but in a non-transactional way.

The examples above use a 'K' an uppercase k used to represent kilo or 1000. According to wiki, kilo or 1000's should be represented in lower case. So, rather than £300K, use £300k or in a code example :-

[>=1000]£#,##0,"k";[red][<=-1000]-£#,##0,"k";0

I use this, if there is an absolute path (this is an example):

$img = imagecreatefromjpeg($_SERVER['DOCUMENT_ROOT']."/Folder-B/image1.jpg");

if there is a picture to show, this is enough:

echo("<img src='/Folder-B/image1.jpg'>");

Minimalistic Solution

Here is a "minimal" solution.

class SortedArrayList<T> extends ArrayList<T> {

    @SuppressWarnings("unchecked")
    public void insertSorted(T value) {
        add(value);
        Comparable<T> cmp = (Comparable<T>) value;
        for (int i = size()-1; i > 0 && cmp.compareTo(get(i-1)) < 0; i--)
            Collections.swap(this, i, i-1);
    }
}

The insert runs in linear time, but that would be what you would get using an ArrayList anyway (all elements to the right of the inserted element would have to be shifted one way or another).

Inserting something non-comparable results in a ClassCastException. (This is the approach taken by PriorityQueue as well: A priority queue relying on natural ordering also does not permit insertion of non-comparable objects (doing so may result in ClassCastException).)

Overriding List.add

Note that overriding List.add (or List.addAll for that matter) to insert elements in a sorted fashion would be a direct violation of the interface specification. What you could do, is to override this method to throw an UnsupportedOperationException.

From the docs of List.add:

boolean add(E e)
    Appends the specified element to the end of this list (optional operation).

Same reasoning applies for both versions of add, both versions of addAll and set. (All of which are optional operations according to the list interface.)

Some tests

SortedArrayList<String> test = new SortedArrayList<String>();

test.insertSorted("ddd");    System.out.println(test);
test.insertSorted("aaa");    System.out.println(test);
test.insertSorted("ccc");    System.out.println(test);
test.insertSorted("bbb");    System.out.println(test);
test.insertSorted("eee");    System.out.println(test);

....prints:

[ddd]
[aaa, ddd]
[aaa, ccc, ddd]
[aaa, bbb, ccc, ddd]
[aaa, bbb, ccc, ddd, eee]

One thing I didn't realize at first when reading the accepted answer was that making an inner class static is basically the same thing as moving it to its own separate class.

Thus, when getting the error

xxx is not an enclosing class

You can solve it in either of the following ways:

• Add the static keyword to the inner class, or
• Move it out to its own separate class.

You could convert the dataframe to be a single column with stack (this changes the shape from 5x3 to 15x1) and then take the standard deviation:

df.stack().std()         # pandas default degrees of freedom is one

Alternatively, you can use values to convert from a pandas dataframe to a numpy array before taking the standard deviation:

df.values.std(ddof=1)    # numpy default degrees of freedom is zero

Unlike pandas, numpy will give the standard deviation of the entire array by default, so there is no need to reshape before taking the standard deviation.

A couple of additional notes:

• The numpy approach here is a bit faster than the pandas one, which is generally true when you have the option to accomplish the same thing with either numpy or pandas. The speed difference will depend on the size of your data, but numpy was roughly 10x faster when I tested a few different sized dataframes on my laptop (numpy version 1.15.4 and pandas version 0.23.4).

• The numpy and pandas approaches here will not give exactly the same answers, but will be extremely close (identical at several digits of precision). The discrepancy is due to slight differences in implementation behind the scenes that affect how the floating point values get rounded.

As Felipe Alsacreations has already said, the first option is fine.

If you want to ensure that nothing below the list is interpreted as belonging to the heading, that's exactly what the HTML5 sectioning content elements are for. So, for instance you could do

<h2>About Fruits</h2>
<section>
  <h3>Fruits I Like:</h3>
  <ul>
    <li>Apples</li>
    <li>Bananas</li>
    <li>Oranges</li>
  </ul>
</section>
<!-- anything here is part of the "About Fruits" section but does not 
     belong to the "Fruits I Like" section. -->

You can use array_sum().

$total = array_sum($group);

Okay, but you all know that the * is a wildcard and allows cross site scripting from every domain?

You would like to send multiple Access-Control-Allow-Origin headers for every site that's allowed to - but unfortunately its officially not supported to send multiple Access-Control-Allow-Origin headers, or to put in multiple origins.

You can solve this by checking the origin, and sending back that one in the header, if it is allowed:

$origin = $_SERVER['HTTP_ORIGIN'];
$allowed_domains = [
    'http://mysite1.com',
    'https://www.mysite2.com',
    'http://www.mysite2.com',
];

if (in_array($origin, $allowed_domains)) {
    header('Access-Control-Allow-Origin: ' . $origin);
}

Thats much safer. You might want to edit the matching and change it to a manual function with some regex, or something like that. At least this will only send back 1 header, and you will be sure its the one that the request came from. Please do note that all HTTP headers can be spoofed, but this header is for the client's protection. Don't protect your own data with those values. If you want to know more, read up a bit on CORS and CSRF.

Why is it safer?

Allowing access from other locations then your own trusted site allows for session highjacking. I'm going to go with a little example - image Facebook allows a wildcard origin - this means that you can make your own website somewhere, and make it fire AJAX calls (or open iframes) to facebook. This means you can grab the logged in info of the facebook of a visitor of your website. Even worse - you can script POST requests and post data on someone's facebook - just while they are browsing your website.

Be very cautious when using the ACAO headers!

Add this CSS rule, and yellow background color will disapear. :)

A SOAP request is an XML file consisting of the parameters you are sending to the server.

The SOAP response is equally an XML file, but now with everything the service wants to give you.

Basically the WSDL is a XML file that explains the structure of those two XML.

To implement simple SOAP clients in Java, you can use the SAAJ framework (it is shipped with JSE 1.6 and above):

SOAP with Attachments API for Java (SAAJ) is mainly used for dealing directly with SOAP Request/Response messages which happens behind the scenes in any Web Service API. It allows the developers to directly send and receive soap messages instead of using JAX-WS.

See below a working example (run it!) of a SOAP web service call using SAAJ. It calls this web service.

import javax.xml.soap.*;

public class SOAPClientSAAJ {

    // SAAJ - SOAP Client Testing
    public static void main(String args[]) {
        /*
            The example below requests from the Web Service at:
             http://www.webservicex.net/uszip.asmx?op=GetInfoByCity


            To call other WS, change the parameters below, which are:
             - the SOAP Endpoint URL (that is, where the service is responding from)
             - the SOAP Action

            Also change the contents of the method createSoapEnvelope() in this class. It constructs
             the inner part of the SOAP envelope that is actually sent.
         */
        String soapEndpointUrl = "http://www.webservicex.net/uszip.asmx";
        String soapAction = "http://www.webserviceX.NET/GetInfoByCity";

        callSoapWebService(soapEndpointUrl, soapAction);
    }

    private static void createSoapEnvelope(SOAPMessage soapMessage) throws SOAPException {
        SOAPPart soapPart = soapMessage.getSOAPPart();

        String myNamespace = "myNamespace";
        String myNamespaceURI = "http://www.webserviceX.NET";

        // SOAP Envelope
        SOAPEnvelope envelope = soapPart.getEnvelope();
        envelope.addNamespaceDeclaration(myNamespace, myNamespaceURI);

            /*
            Constructed SOAP Request Message:
            <SOAP-ENV:Envelope xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/" xmlns:myNamespace="http://www.webserviceX.NET">

        // SOAP Body
        SOAPBody soapBody = envelope.getBody();
        SOAPElement soapBodyElem = soapBody.addChildElement("GetInfoByCity", myNamespace);
        SOAPElement soapBodyElem1 = soapBodyElem.addChildElement("USCity", myNamespace);
        soapBodyElem1.addTextNode("New York");
    }

    private static void callSoapWebService(String soapEndpointUrl, String soapAction) {
        try {
            // Create SOAP Connection
            SOAPConnectionFactory soapConnectionFactory = SOAPConnectionFactory.newInstance();
            SOAPConnection soapConnection = soapConnectionFactory.createConnection();

            SOAPMessage soapResponse = soapConnection.call(createSOAPRequest(soapAction), soapEndpointUrl);

            // Print the SOAP Response
            System.out.println("Response SOAP Message:");
            soapResponse.writeTo(System.out);
            System.out.println();

            soapConnection.close();
        } catch (Exception e) {
            System.err.println("\nError occurred while sending SOAP Request to Server!\nMake sure you have the correct endpoint URL and SOAPAction!\n");
            e.printStackTrace();
        }
    }

    private static SOAPMessage createSOAPRequest(String soapAction) throws Exception {
        MessageFactory messageFactory = MessageFactory.newInstance();
        SOAPMessage soapMessage = messageFactory.createMessage();

        createSoapEnvelope(soapMessage);

        MimeHeaders headers = soapMessage.getMimeHeaders();
        headers.addHeader("SOAPAction", soapAction);

        soapMessage.saveChanges();

        /* Print the request message, just for debugging purposes */
        System.out.println("Request SOAP Message:");
        soapMessage.writeTo(System.out);
        System.out.println("\n");

        return soapMessage;
    }

}

I had got the same problem and this following code answered perfectly at this problem :

//Identificate separator
string boundary = "---------------------------" + DateTime.Now.Ticks.ToString("x");
//Encoding
byte[] boundarybytes = System.Text.Encoding.ASCII.GetBytes("\r\n--" + boundary + "\r\n");

//Creation and specification of the request
HttpWebRequest wr = (HttpWebRequest)WebRequest.Create(url); //sVal is id for the webService
wr.ContentType = "multipart/form-data; boundary=" + boundary;
wr.Method = "POST";
wr.KeepAlive = true;
wr.Credentials = System.Net.CredentialCache.DefaultCredentials;

string sAuthorization = "login:password";//AUTHENTIFICATION BEGIN
byte[] toEncodeAsBytes = System.Text.ASCIIEncoding.ASCII.GetBytes(sAuthorization);
string returnValue = System.Convert.ToBase64String(toEncodeAsBytes);
wr.Headers.Add("Authorization: Basic " + returnValue); //AUTHENTIFICATION END
Stream rs = wr.GetRequestStream();


string formdataTemplate = "Content-Disposition: form-data; name=\"{0}\"\r\n\r\n{1}"; //For the POST's format

//Writting of the file
rs.Write(boundarybytes, 0, boundarybytes.Length);
byte[] formitembytes = System.Text.Encoding.UTF8.GetBytes(Server.MapPath("questions.pdf"));
rs.Write(formitembytes, 0, formitembytes.Length);

rs.Write(boundarybytes, 0, boundarybytes.Length);

string headerTemplate = "Content-Disposition: form-data; name=\"{0}\"; filename=\"{1}\"\r\nContent-Type: {2}\r\n\r\n";
string header = string.Format(headerTemplate, "file", "questions.pdf", contentType);
byte[] headerbytes = System.Text.Encoding.UTF8.GetBytes(header);
rs.Write(headerbytes, 0, headerbytes.Length);

FileStream fileStream = new FileStream(Server.MapPath("questions.pdf"), FileMode.Open, FileAccess.Read);
byte[] buffer = new byte[4096];
int bytesRead = 0;
while ((bytesRead = fileStream.Read(buffer, 0, buffer.Length)) != 0)
{
    rs.Write(buffer, 0, bytesRead);
}
fileStream.Close();

byte[] trailer = System.Text.Encoding.ASCII.GetBytes("\r\n--" + boundary + "--\r\n");
rs.Write(trailer, 0, trailer.Length);
rs.Close();
rs = null;

WebResponse wresp = null;
try
{
    //Get the response
    wresp = wr.GetResponse();
    Stream stream2 = wresp.GetResponseStream();
    StreamReader reader2 = new StreamReader(stream2);
    string responseData = reader2.ReadToEnd();
}
catch (Exception ex)
{
    string s = ex.Message;
}
finally
{
    if (wresp != null)
    {
        wresp.Close();
        wresp = null;
    }
    wr = null;
}

Both the options can be correct depending on your situation.

A very simple example would be: If you have multiple constructors all of which initialize the variable the same way(int x=2 for each one of them). It makes sense to initialize the variable at declaration to avoid redundancy.

It also makes sense to consider final variables in such a situation. If you know what value a final variable will have at declaration, it makes sense to initialize it outside the constructors. However, if you want the users of your class to initialize the final variable through a constructor, delay the initialization until the constructor.

Android follows normal java package conventions plus here is an important snippet of text to read (this is important regarding the wide use of xml files while developing on android).

The reason for having it in reverse order is to do with the layout on the storage media. If you consider each period ('.') in the application name as a path separator, all applications from a publisher would sit together in the path hierarchy. So, for instance, packages from Adobe would be of the form:

com.adobe.reader (Adobe Reader)

com.adobe.photoshop (Adobe Photoshop)

com.adobe.ideas (Adobe Ideas)

[Note that this is just an illustration and these may not be the exact package names.]

These could internally be mapped (respectively) to:

com/adobe/reader

com/adobe/photoshop

com/adobe/ideas

The concept comes from Package Naming Conventions in Java, more about which can be read here:*

http://en.wikipedia.org/wiki/Java_package#Package_naming_conventions

Source: http://www.quora.com/Why-do-a-majority-of-Android-package-names-begin-with-com

It's not really a programming question, but it's a quick one so let me answer that. MySQL Workbench's themes are a collection of colors for certain main parts of the application. It is planned to allow customizing them in a later version. In order to get a dark theme as one of the templates please file a feature request at http://bugs.mysql.com. But keep in mind, not every UI element is colored according to the Workbench theme, e.g. text boxes still stay white as they use the Windows standard colors.

Version Installed:

Using webpack CLI: (--version, -v Show version number [boolean])

webpack --version

or:

webpack -v

Using npm list command:

npm list webpack

Results in name@version-range:

<projectName>@<projectVersion> /path/to/project
+-- webpack@<version-range>

Using yarn list command:

yarn list webpack

How to do it programmatically?

Webpack 2 introduced Configuration Types.

Instead of exporting a configuration object, you may return a function which accepts an environment as argument. When running webpack, you may specify build environment keys via --env, such as --env.production or --env.platform=web.

We will use a build environment key called --env.version.

webpack --env.version $(webpack --version)

or:

webpack --env.version $(webpack -v)

For this to work we will need to do two things:

Change our webpack.config.js file and use DefinePlugin.

The DefinePlugin allows you to create global constants which can be configured at compile time.

-module.exports = {
+module.exports = function(env) {
+  return {
    plugins: [
      new webpack.DefinePlugin({
+        WEBPACK_VERSION: JSON.stringify(env.version) //<version-range>
      })
    ]
+  };
};

Now we can access the global constant like so:

console.log(WEBPACK_VERSION);

Latest version available:

Using npm view command will return the latest version available on the registry:

npm view [<@scope>/]<name>[@<version>] [<field>[.<subfield>]...]

For webpack use:

npm view webpack version

In your request options, try including the following:

   var req = https.request({ 
      host: '192.168.1.1', 
      port: 443,
      path: '/',
      method: 'GET',
      rejectUnauthorized: false,
      requestCert: true,
      agent: false
    },

Simple and easy way to get File name

File file = new File("/storage/sdcard0/DCIM/Camera/1414240995236.jpg"); 
String strFileName = file.getName();

After add this code and print strFileName you will get strFileName = 1414240995236.jpg

If you need to open Emacs without X:

emacs -nw

Here is a possible solution the solution #3 on my comments to blubill's answer:

yourscript.php
========================
<?php
    $dir = '/home/user/Pictures';
    $file_display = array('jpg', 'jpeg', 'png', 'gif');

    if (file_exists($dir) == false) 
    {
        echo 'Directory "', $dir, '" not found!';
    } 
    else 
    {
        $dir_contents = scandir($dir);

        foreach ($dir_contents as $file) 
        {
            $file_type = strtolower(end(explode('.', $file)));
            if ($file !== '.' && $file !== '..' && in_array($file_type, $file_display) == true)     
            {
                $name = basename($file);
                echo "<img src='img.php?name={$name}' />";
            }
        }
    }
?>


img.php
========================
<?php
    $name = $_GET['name'];
    $mimes = array
    (
        'jpg' => 'image/jpg',
        'jpeg' => 'image/jpg',
        'gif' => 'image/gif',
        'png' => 'image/png'
    );

    $ext = strtolower(end(explode('.', $name)));

    $file = '/home/users/Pictures/'.$name;
    header('content-type: '. $mimes[$ext]);
    header('content-disposition: inline; filename="'.$name.'";');
    readfile($file);
?>

Here's a simple function that does what you need:

<script type="text/javascript">
function minmax(value, min, max) 
{
    if(parseInt(value) < min || isNaN(parseInt(value))) 
        return min; 
    else if(parseInt(value) > max) 
        return max; 
    else return value;
}
</script>
<input type="text" name="textWeight" id="txtWeight" maxlength="5" onkeyup="this.value = minmax(this.value, 0, 100)"/>

If the input is not numeric it replaces it with a zero

The only guarantees are that char must be at least 8 bits wide, short and int must be at least 16 bits wide, and long must be at least 32 bits wide, and that sizeof (char) <= sizeof (short) <= sizeof (int) <= sizeof (long) (same is true for the unsigned versions of those types).

int may be anywhere from 16 to 64 bits wide depending on the platform.

    public class StructMain implements Serializable {
    public  int id;
    public String name;
    public String lastName;
}

this my item . implement Serializable and create ArrayList

ArrayList<StructMain> items =new ArrayList<>();

and put in Bundle

Bundle bundle=new Bundle();
bundle.putSerializable("test",items);

and create a new Intent that put Bundle to Intent

Intent intent=new Intent(ActivityOne.this,ActivityTwo.class);
intent.putExtras(bundle);
startActivity(intent);

for receive bundle insert this code

Bundle bundle = getIntent().getExtras();
ArrayList<StructMain> item = (ArrayList<StructMain>) bundle.getSerializable("test");

Just add disabled as a class on your anchor:

<a class="dropdown-toggle disabled" href="http://google.com">
    Dropdown <b class="caret"></b></a>

So all together something like:

<ul class="nav">
    <li class="dropdown">
        <a class="dropdown-toggle disabled" href="http://google.com">
            Dropdown <b class="caret"></b>
        </a>
        <ul class="dropdown-menu">
            <li><a href="#">Link 1</a></li>
            <li><a href="#">Link 2</a></li>
        </ul>
    </li>
</ul>

Arraylist narraylist=Arrays.asList(); // Returns immutable arraylist To make it mutable solution would be: Arraylist narraylist=new ArrayList(Arrays.asList());

I have not compiled this as it is meant for a proof of concept. This is how I have implemented a Progress bar for database access in the past. This example shows access to a SQLite database using the System.Data.SQLite module

private void backgroundWorker1_DoWork(object sender, DoWorkEventArgs e)

wrap button inside <div class="text-xs-center">

<div class="text-xs-center">
  <v-btn primary>
    Signup
  </v-btn>
</div>

Dev uses it in his examples.

For centering buttons in v-card-actions we can add class="justify-center" (note in v2 class is text-center (so without xs):

<v-card-actions class="justify-center">
  <v-btn>
    Signup
  </v-btn>
</v-card-actions>

It is generally a bad idea overriding the default behavior of the web browser. A client-side script does not have the sufficient privilege to do this for security reasons.

There are a few similar questions asked as well,

• How can I prevent the backspace key from navigating back?

• How can I prevent the browser's default history back action for the backspace button with JavaScript?

You can-not actually disable the browser back button. However, you can do magic using your logic to prevent the user from navigating back which will create an impression like it is disabled. Here is how - check out the following snippet.

(function (global) {

    if(typeof (global) === "undefined") {
        throw new Error("window is undefined");
    }

    var _hash = "!";
    var noBackPlease = function () {
        global.location.href += "#";

        // Making sure we have the fruit available for juice (^__^)
        global.setTimeout(function () {
            global.location.href += "!";
        }, 50);
    };

    global.onhashchange = function () {
        if (global.location.hash !== _hash) {
            global.location.hash = _hash;
        }
    };

    global.onload = function () {
        noBackPlease();

        // Disables backspace on page except on input fields and textarea..
        document.body.onkeydown = function (e) {
            var elm = e.target.nodeName.toLowerCase();
            if (e.which === 8 && (elm !== 'input' && elm  !== 'textarea')) {
                e.preventDefault();
            }
            // Stopping the event bubbling up the DOM tree...
            e.stopPropagation();
        };
    }
})(window);

This is in pure JavaScript, so it would work in most of the browsers. It would also disable the backspace key, but that key will work normally inside input fields and textarea.

Recommended Setup:

Place this snippet in a separate script and include it on a page where you want this behavior. In the current setup it will execute the onload event of the DOM which is the ideal entry point for this code.

Working DEMO!

It was tested and verified in the following browsers,

• Chrome.
• Firefox.
• Internet Explorer (8-11) and Edge.
• Safari.

Simplest way:

var uriSource = new Uri("image path here");
image1.Source = new BitmapImage(uriSource);

var d = new Date();

var curr_date = d.getDate();

var curr_month = d.getMonth();

var curr_year = d.getFullYear();

document.write(curr_date + "-" + curr_month + "-" + curr_year);

using this you can format date.

you can change the appearance in the way you want then

You need to keep an array of the google.maps.Marker objects to hide (or remove or run other operations on them).

In the global scope:

var gmarkers = [];

Then push the markers on that array as you create them:

var marker = new google.maps.Marker({
    position: new google.maps.LatLng(locations[i].latitude, locations[i].longitude),
    title: locations[i].title,
    icon: icon,
    map:map
});

// Push your newly created marker into the array:
gmarkers.push(marker);

Then to remove them:

function removeMarkers(){
    for(i=0; i<gmarkers.length; i++){
        gmarkers[i].setMap(null);
    }
}

working example (toggles the markers)
