Programs & Examples On #Battery

Since SDK 21 LOLLIPOP it is possible to use the following to get current battery level as a percentage:

BatteryManager bm = (BatteryManager) context.getSystemService(BATTERY_SERVICE);
int batLevel = bm.getIntProperty(BatteryManager.BATTERY_PROPERTY_CAPACITY);

another thing you could try is to rename your old jdk folder, lets say its:

C:\Program Files\Java\jdk1.7.0_04

change it to saomething like:

C:\Program Files\Java\xxxjdk1.7.0_04

Now, you should once again asked to set your jdk folder location on Oracle SqlDeveloper launch, and you can chose the right path.

Not the most elegant solution, but it worked for me.

Try using below code:

private enum ElementStatus{
        VISIBLE,
        NOTVISIBLE,
        ENABLED,
        NOTENABLED,
        PRESENT,
        NOTPRESENT
    }
    private ElementStatus isElementVisible(WebDriver driver, By by,ElementStatus getStatus){
        try{
            if(getStatus.equals(ElementStatus.ENABLED)){
                if(driver.findElement(by).isEnabled())
                    return ElementStatus.ENABLED;
                return ElementStatus.NOTENABLED; 
            }
            if(getStatus.equals(ElementStatus.VISIBLE)){
                if(driver.findElement(by).isDisplayed())
                    return ElementStatus.VISIBLE;
                return ElementStatus.NOTVISIBLE;
            }
            return ElementStatus.PRESENT;
        }catch(org.openqa.selenium.NoSuchElementException nse){
            return ElementStatus.NOTPRESENT;
        }
    }

I was taught that for arrays, length is not retrieved through a method due to the following fear: programmers would just assign the length to a local variable before entering a loop (think a for loop where the conditional uses the array's length.) The programmer would supposedly do so to trim down on function calls (and thereby improve performance.) The problem is that the length might change during the loop, and the variable wouldn't.

Nevermind, the answer is raw triple-quoted strings:

r"""what"ever"""

Use this command, (go to java < jdk < bin path in cmd prompt)

$ jarsigner -verify -verbose -certs my_application.apk

If you see "CN=Android Debug", this means the .apk was signed with the debug key generated by the Android SDK (means it is unsigned), otherwise you will find something for CN. For more details see: http://developer.android.com/guide/publishing/app-signing.html

You can find it here: RTL Bootstrap v3.2.0.

Press the Shift key when scrolling the mouse up/down works for me when loggin in Ubuntu using Terminal ssh in Yosemite.

There is a standard feature echo: in cmd/bat-files to write blank line, which emulates a new line in your cmd-output:

@echo off
@echo line1
@echo:
@echo line2

Output of cited above cmd-file:

line1

line2

Now, i'm being told that this will terminate the session (or is it all sessions?) in the 15th minute of use, regardless their activity.

This is wrong. It will just kill the session when the associated client (webbrowser) has not accessed the website for more than 15 minutes. The activity certainly counts, exactly as you initially expected, seeing your attempt to solve this.

The HttpSession#setMaxInactiveInterval() doesn't change much here by the way. It does exactly the same as <session-timeout> in web.xml, with the only difference that you can change/set it programmatically during runtime. The change by the way only affects the current session instance, not globally (else it would have been a static method).

To play around and experience this yourself, try to set <session-timeout> to 1 minute and create a HttpSessionListener like follows:

@WebListener
public class HttpSessionChecker implements HttpSessionListener {

    public void sessionCreated(HttpSessionEvent event) {
        System.out.printf("Session ID %s created at %s%n", event.getSession().getId(), new Date());
    }

    public void sessionDestroyed(HttpSessionEvent event) {
        System.out.printf("Session ID %s destroyed at %s%n", event.getSession().getId(), new Date());
    }

}

(if you're not on Servlet 3.0 yet and thus can't use @WebListener, then register in web.xml as follows):

<listener>
    <listener-class>com.example.HttpSessionChecker</listener-class>
</listener>

Note that the servletcontainer won't immediately destroy sessions after exactly the timeout value. It's a background job which runs at certain intervals (e.g. 5~15 minutes depending on load and the servletcontainer make/type). So don't be surprised when you don't see destroyed line in the console immediately after exactly one minute of inactivity. However, when you fire a HTTP request on a timed-out-but-not-destroyed-yet session, it will be destroyed immediately.

Add android:checked = "true" in your activity.xml

I ran into this on a friend's HTML code and in his case, he was missing quotes.

For example:

<form action="formHandler.php" name="yourForm" id="theForm" method="post">    
<input type="text" name="fname" id="fname" style="width:90;font-size:10>     
<input type="submit" value="submit"/>
</form>

In this example, a missing quote on the input text fname will simply render the submit button un-usable and the form will not submit.

Of course, this is a bad example because I should be using CSS in the first place ;) but anyways, check all your single and double quotes to see that they are closing properly.

Also, if you have any tags like center, move them out of the form.

<form action="formHandler.php" name="yourForm" id="theForm" method="post">  
<center> <-- bad

As strange it may seems, it can have an impact.

$host is a variable of the Core module.

$host

This variable is equal to line Host in the header of request or name of the server processing the request if the Host header is not available.

This variable may have a different value from $http_host in such cases: 1) when the Host input header is absent or has an empty value, $host equals to the value of server_name directive; 2)when the value of Host contains port number, $host doesn't include that port number. $host's value is always lowercase since 0.8.17.

$http_host is also a variable of the same module but you won't find it with that name because it is defined generically as $http_HEADER (ref).

$http_HEADER

The value of the HTTP request header HEADER when converted to lowercase and with 'dashes' converted to 'underscores', e.g. $http_user_agent, $http_referer...;

Summarizing:

• $http_host equals always the HTTP_HOST request header.
• $host equals $http_host, lowercase and without the port number (if present), except when HTTP_HOST is absent or is an empty value. In that case, $host equals the value of the server_name directive of the server which processed the request.

To remove .idea/ completely from the git without affecting your IDE config you could just do:

git rm -r --cached '.idea/'
echo .idea >> .gitignore
git commit -am "removed .idea/ directory"

To kill from the application, you can do:

android.os.Process.killProcess(android.os.Process.myPid());

Why must it work?

The JLS 5, Section 15.18.1.1 JLS 8 § 15.18.1 "String Concatenation Operator +", leading to JLS 8, § 5.1.11 "String Conversion", requires this operation to succeed without failure:

...Now only reference values need to be considered. If the reference is null, it is converted to the string "null" (four ASCII characters n, u, l, l). Otherwise, the conversion is performed as if by an invocation of the toString method of the referenced object with no arguments; but if the result of invoking the toString method is null, then the string "null" is used instead.

How does it work?

Let's look at the bytecode! The compiler takes your code:

String s = null;
s = s + "hello";
System.out.println(s); // prints "nullhello"

and compiles it into bytecode as if you had instead written this:

String s = null;
s = new StringBuilder(String.valueOf(s)).append("hello").toString();
System.out.println(s); // prints "nullhello"

(You can do so yourself by using javap -c)

The append methods of StringBuilder all handle null just fine. In this case because null is the first argument, String.valueOf() is invoked instead since StringBuilder does not have a constructor that takes any arbitrary reference type.

If you were to have done s = "hello" + s instead, the equivalent code would be:

s = new StringBuilder("hello").append(s).toString();

where in this case the append method takes the null and then delegates it to String.valueOf().

Note: String concatenation is actually one of the rare places where the compiler gets to decide which optimization(s) to perform. As such, the "exact equivalent" code may differ from compiler to compiler. This optimization is allowed by JLS, Section 15.18.1.2:

To increase the performance of repeated string concatenation, a Java compiler may use the StringBuffer class or a similar technique to reduce the number of intermediate String objects that are created by evaluation of an expression.

The compiler I used to determine the "equivalent code" above was Eclipse's compiler, ecj.

This algorithm is not optimal for winning the game, but it is fairly optimal in terms of performance and amount of code needed:

  if(can move neither right, up or down)
    direction = left
  else
  {
    do
    {
      direction = random from (right, down, up)
    }
    while(can not move in "direction")
  }

Without any iteration with the --line-buffered grep option:

your_command | grep --line-buffered "your search"

Real life exemple with a Symfony PHP Framework router debug command ouput, to grep all "api" related routes:

php bin/console d:r | grep --line-buffered "api"

Easiest solution:

class OuterClass:
    outer_var = 1
    class InnerClass:
        def __init__(self):
            self.inner_var = OuterClass.outer_var

It requires you to be explicit, but doesn't take much effort.

There is a handy 'Connect' option in the 'Instance Actions' menu for the EC2 instance. It will give you the exact SSH command to execute with the correct url for the instance. Jabley's overall instructions are correct.

I would check the "End of File" flag:

If temp_rst1.EOF Or temp_rst2.EOF Then MsgBox "null"

I found a quick and easy solution to what I wanted using json_normalize() included in pandas 1.01.

from urllib2 import Request, urlopen
import json

import pandas as pd    

path1 = '42.974049,-81.205203|42.974298,-81.195755'
request=Request('http://maps.googleapis.com/maps/api/elevation/json?locations='+path1+'&sensor=false')
response = urlopen(request)
elevations = response.read()
data = json.loads(elevations)
df = pd.json_normalize(data['results'])

This gives a nice flattened dataframe with the json data that I got from the Google Maps API.

Switch is not a good way to go as it breaks the Open Close Principal. This is how I do it.

public class Animal
{
       public abstract void Speak();
}


public class Dog : Animal
{
   public virtual void Speak()
   {
       Console.WriteLine("Hao Hao");
   }
}

public class Cat : Animal
{
   public virtual void Speak()
   {
       Console.WriteLine("Meauuuu");
   }
}

And here is how to use it (taking your code):

foreach (var animal in zoo) 
{
    echo animal.speak();
}

Basically what we are doing is delegating the responsibility to the child class instead of having the parent decide what to do with children.

Simply executing command

git init

before cloning resolved it for me.

This is a simple answer, this will allow you to clear the screen for example. There are two examples below, with eval and exec, that will print 0 at the top after cleaning (if you're using Windows, change clear to cls, Linux and Mac users leave as is for example) or just execute it, respectively.

eval("os.system(\"clear\")")
exec("os.system(\"clear\")")

here is my solution to this problem:

<td>Total: {{ calculateTotal() }}</td>

script

$scope.calculateVAT = function () {
    return $scope.cart.products.reduce((accumulator, currentValue) => accumulator + (currentValue.price * currentValue.quantity), 0);
};

reduce will execute for each product in products array. Accumulator is the total accumulated amount, currentValue is the current element of the array and the 0 in the last is the initial value

This one is like the answer above which uses the MySql DATE_FORMAT() function. I also selected just one specific week in Jan.

SELECT 
    DatePart(day, DateAdded) AS date, 
    COUNT(entryhash) AS count 
FROM Responses 
    where DateAdded > '2020-01-25' and DateAdded < '2020-02-01' 
GROUP BY 
    DatePart(day, DateAdded )

The other answers are correct but if you're doing numerical work, you might want to consider numpy. Using numpy, the answer is:

v = numpy.diff(t)

You can include the script file directly in your page/master page, etc using:

 <script type="text/javascript" src="/scripts/jquery.min.js"></script> 

Us use a Content Delivery network like Google or Microsoft:

<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> 

or:

<script src="http://ajax.microsoft.com/ajax/jquery/jquery-1.4.2.js" type="text/javascript"></script>     

Easier alternative to above answers

1. If Object(Model Class/POJO) contains the date in String datatype.

   private void sortArray(ArrayList<myObject> arraylist) {
   SimpleDateFormat simpleDateFormat = new SimpleDateFormat("yyyy-MM-dd'T'HH:mm:ss.SSS'Z'"); //your own date format
   if (reports != null) {
       Collections.sort(arraylist, new Comparator<myObject>() {
           @Override
           public int compare(myObject o1, myObject o2) {
               try {
                   return simpleDateFormat.parse(o2.getCreated_at()).compareTo(simpleDateFormat.parse(o1.getCreated_at()));
               } catch (ParseException e) {
                   e.printStackTrace();
                   return 0;
               }
           }
       });
   }
   

2. If Object(Model Class/POJO) contains date in Date datatype

   private void sortArray(ArrayList<myObject> arrayList) {
   if (arrayList != null) {
       Collections.sort(arrayList, new Comparator<myObject>() {
           @Override
           public int compare(myObject o1, myObject o2) {
               return o2.getCreated_at().compareTo(o1.getCreated_at()); }
       });
   } }
   

The above code is for sorting the array in descending order of date, swap o1 and o2 for ascending order.

In Typescript use the For Each like below.

selectChildren(data, $event) {
let parentChecked = data.checked;
for(var obj in this.hierarchicalData)
    {
        for (var childObj in obj )
        {
            value.checked = parentChecked;
        }
    }
}

Although other answers are correct they are setting the global config value whereas there is a default git location for the global git ignore file:

*nix:

~/.config/git/ignore

Windows:

%USERPROFILE%\git\ignore

You may need to create git directory and ignore file but then you can put your global ignores into that file and that's it!

Source

Which file to place a pattern in depends on how the pattern is meant to be used.

…

• Patterns which a user wants Git to ignore in all situations (e.g., backup or temporary files generated by the user’s editor of choice) generally go into a file specified by core.excludesFile in the user’s ~/.gitconfig. Its default value is $XDG_CONFIG_HOME/git/ignore. If $XDG_CONFIG_HOME is either not set or empty, $HOME/.config/git/ignore is used instead.

I believe your problem is that you are passing testFunct a string, and not a function object, (is that even possible?)

I needed to run two versions of tfjs-core and found that both needed to be built after being installed.

package.json:

"dependencies": {
  "tfjs-core-0.14.3": "git://github.com/tensorflow/tfjs-core#bb0a830b3bda1461327f083ceb3f889117209db2",
  "tfjs-core-1.1.0": "git://github.com/tensorflow/tfjs-core#220660ed8b9a252f9d0847a4f4e3c76ba5188669"
}

Then:

cd node_modules/tfjs-core-0.14.3 && yarn install && yarn build-npm && cd ../../
cd node_modules/tfjs-core-1.1.0  && yarn install && yarn build-npm && cd ../../

And finally, to use the libraries:

import * as tf0143 from '../node_modules/tfjs-core-0.14.3/dist/tf-core.min.js';
import * as tf110 from '../node_modules/tfjs-core-1.1.0/dist/tf-core.min.js';

GUYS ITS NOT THAT EASY:- PLEASE FOLLOW BELOW STEP TO GET TO MARK

So here's what I did to finish a 64-bit build on Windows:

Download and install MinGW-64: sourceforge.net /projects/mingw-w64/

On the first screen of the install prompt make sure you set the Architecture to x86_64 and the Threads to win32 I installed to C:\mingw64 (to avoid spaces in the file path) so I added this to my PATH environment variable: C:\ mingw64 \ mingw64 \ bin(Please remove spaces)

I also noticed that the make utility that is included in bin\mingw64 is called mingw32-make so to simplify things I just renamed this to make

Open a Windows command prompt and type gcc. You should see something like "fatal error: no input file"

Next type make. You should see something like "No targets specified and no makefile found"

Type git. If you don't have git, install it and add it to your PATH. These should be all the tools you need to build the xgboost project. To get the source code run these lines:

• cd c:\
• git clone --recursive https://github.com/dmlc/xgboost
• cd xgboost
• git submodule init
• git submodule update
• cp make/mingw64.mk config.mk
• make -j4 Note that I ran this part from a Cygwin shell. If you are using the Windows command prompt you should be able to change cp to copy and arrive at the same result. However, if the build fails on you for any reason I would recommend trying again using cygwin.

If the build finishes successfully, you should have a file called xgboost.exe located in the project root. To install the Python package, do the following:

• cd python-package

• python setup.py install Now you should be good to go. Open up Python, and you can import the package with:

• import xgboost as xgb To test the installation, I went ahead and ran the basic_walkthrough.py file that was included in the demo/guide-python folder of the project and didn't get any errors.

Minor update in @Joran's code.
Using the code below, you can avoid the ambiguity and only get the unique of two columns:

dat <- data.frame(id=c(1,1,3), id2=c(1,1,4) ,somevalue=c("x","y","z"))    
dat[row.names(unique(dat[,c("id", "id2")])), c("id", "id2")]

You can use one and more echo statement inside href

<a href="profile.php?usr=<?php echo $_SESSION['firstname']."&email=". $_SESSION['email']; ?> ">Link</a>

link : "/profile.php?usr=firstname&email=email"

Select *  from  emp where joindate between date1 and date2;

But this query not show proper data.

Eg

1-jan-2013 to 12-jan-2013.

But it's show data

1-jan-2013 to 11-jan-2013.

What about Microsoft's Visual Studio Express? http://www.microsoft.com/express/default.aspx SQL Server Express is also at that link...

All other answers are useful but they may not help you in case nginx is not on PATH so you're getting command not found when trying to run nginx:

I have nginx 1.2.1 on Debian 7 Wheezy, the nginx executable is not on PATH, so I needed to locate it first. It was already running, so using ps aux | grep nginx I have found out that it's located on /usr/sbin/nginx, therefore I needed to run /usr/sbin/nginx -t.

If you want to use a non-default configuration file (i.e. not /etc/nginx/nginx.conf), run it with the -c parameter: /usr/sbin/nginx -c <path-to-configuration> -t.

You may also need to run it as root, otherwise nginx may not have permissions to open for example logs, so the command would fail.

This way of specifying the encoding of a Python file comes from PEP 0263 - Defining Python Source Code Encodings.

It is also recognized by GNU Emacs (see Python Language Reference, 2.1.4 Encoding declarations), though I don't know if it was the first program to use that syntax.

What you are looking for is called Geocoding.

Google provides a Geocoding Web Service which should do what you're looking for. You will be able to do geocoding on your server.

JSON Example:

http://maps.google.com/maps/api/geocode/json?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA

XML Example:

http://maps.google.com/maps/api/geocode/xml?address=1600+Amphitheatre+Parkway,+Mountain+View,+CA

Edit:

Please note that this is now a deprecated method and you must provide your own Google API key to access this data.

I agree that in most cases you should choose the flexibility and elegance of ArrayLists over arrays - and in most cases the impact to program performance will be negligible.

However, if you're doing constant, heavy iteration with little structural change (no adds and removes) for, say, software graphics rendering or a custom virtual machine, my sequential access benchmarking tests show that ArrayLists are 1.5x slower than arrays on my system (Java 1.6 on my one year-old iMac).

Some code:

import java.util.*;

public class ArrayVsArrayList {
    static public void main( String[] args ) {

        String[] array = new String[300];
        ArrayList<String> list = new ArrayList<String>(300);

        for (int i=0; i<300; ++i) {
            if (Math.random() > 0.5) {
                array[i] = "abc";
            } else {
                array[i] = "xyz";
            }

            list.add( array[i] );
        }

        int iterations = 100000000;
        long start_ms;
        int sum;

        start_ms = System.currentTimeMillis();
        sum = 0;

        for (int i=0; i<iterations; ++i) {
          for (int j=0; j<300; ++j) sum += array[j].length();
        }

        System.out.println( (System.currentTimeMillis() - start_ms) + " ms (array)" );
        // Prints ~13,500 ms on my system

        start_ms = System.currentTimeMillis();
        sum = 0;

        for (int i=0; i<iterations; ++i) {
          for (int j=0; j<300; ++j) sum += list.get(j).length();
        }

        System.out.println( (System.currentTimeMillis() - start_ms) + " ms (ArrayList)" );
        // Prints ~20,800 ms on my system - about 1.5x slower than direct array access
    }
}

In addition to other answers which helped me, you can also add to surrounding div. In my case this was for sign on with user Name/Password fields.

<div (keyup.enter)="login()" class="container-fluid">

You have a lot of variants for using @RequestParam with additional optional elements, e.g.

@RequestParam(required = false, defaultValue = "someValue", value="someAttr") String someAttr

If you don't put required = false - param will be required by default.

defaultValue = "someValue" - the default value to use as a fallback when the request parameter is not provided or has an empty value.

If request and method param are the same - you don't need value = "someAttr"

Here are a few resources you might consider: Creating Zip archives in .NET (without an external library like SharpZipLib)

Zip Your Streams with System.IO.Packaging

My recommendation and preference would be to use system.io.packacking. This keeps your dependencies down (just the framework). Jgalloway’s post (the first reference) provides a good example of adding two files to a zip file. Yes, it is more verbose, but you can easily create a façade (to a degree his AddFileToZip does that).

HTH

I had this problem with no detectable lock files. I found the solution here: http://schooner.uwaterloo.ca/twiki/bin/view/MAG/HgLockError

Here is a transcript from Tortoise Hg Workbench console

% hg debuglocks
lock:  user None, process 7168, host HPv32 (114213199s)
wlock: free
[command returned code 1 Sat Jan 07 18:00:18 2017]
% hg debuglocks --force-lock
[command completed successfully Sat Jan 07 18:03:15 2017]
cmdserver: Process crashed
PaniniDev% hg debuglocks
% hg debuglocks
lock:  free
wlock: free
[command completed successfully Sat Jan 07 18:03:30 2017]

After this the aborted pull ran sucessfully.

The lock had been set more than 2 years ago, by a process on a machine that is no longer on the LAN. Shame on the hg developers for a) not documenting locks adequately; b) not timestamping them for automatic removal when they get stale.

After checking the XHTML DTD I discovered that a <TD>-element is allowed to contain block elements like headings, lists and also <DIV>-elements. Thus, using a <DIV>-element inside a <TD>-element does not violate the XHTML standard. I'm pretty sure that other modern variations of HTML have an equivalent content model for the <TD>-element.

Here are the relevant DTD rules:

<!ELEMENT td %Flow;>
<!-- %Flow; mixes block and inline and is used for list items etc. -->
<!ENTITY %Flow "(#PCDATA | %block; | form | %inline; | %misc;>
<!ENTITY %block "p | %heading; | div | %lists; | %blocktext; | fieldset | table">

Here's a suggestion for getting the first and last days of the week for a month:

-- Build a temp table with all the dates of the month 
drop table #tmp_datesforMonth 
go

declare @begDate datetime
declare @endDate datetime

set @begDate = '6/1/13'
set @endDate = '6/30/13';

WITH N(n) AS  
(   SELECT 0  
        UNION ALL 
    SELECT n+1 
    FROM N 
    WHERE n <= datepart(dd,@enddate)
)
SELECT      DATEADD(dd,n,@BegDate) as dDate 
into #tmp_datesforMonth
FROM        N
WHERE       MONTH(DATEADD(dd,n,@BegDate)) = MONTH(@BegDate)

--- pull results showing the weeks' dates and the week # for the month (not the week # for the current month) 

select  MIN(dDate) as BegOfWeek
, MAX(dDate) as EndOfWeek 
, datediff(week, dateadd(week, datediff(week, 0, dateadd(month, datediff(month, 0, dDate), 0)), 0), dDate) as WeekNumForMonth 
from #tmp_datesforMonth
group by datediff(week, dateadd(week, datediff(week, 0, dateadd(month, datediff(month, 0, dDate), 0)), 0), dDate) 
order by 3, 1

I would like to propose a solution for numpy that worked well for me. The line

from numpy import inf
inputArray[inputArray == inf] = np.finfo(np.float64).max

substitues all infite values of a numpy array with the maximum float64 number.

If a is your array:

In [11]: a[:,:2]
Out[11]: 
array([[-0.57098887, -0.4274751 ],
       [-0.22279713, -0.51723555],
       [ 0.67492385, -0.69294472],
       [ 0.41086611,  0.26374238]])

I would have to agree a foreach would be a lot easier something like

foreach(AllIntegerIDs allIntegerIDs in integerList)
{
Console.WriteLine("{0}\t{1}\t{2}\t{3}\t{4}\n", allIntegerIDs.m_MessageID,
allIntegerIDs.m_MessageType,
allIntegerIDs.m_ClassID,
allIntegerIDs.m_CategoryID,
allIntegerIDs.m_MessageText);
}

Also I would suggest you add properties to access your information instead of public fields, depending on your .net version you can add it like public int MessageType {get; set;} and get rid of the m_ from your public fields, properties etc as it shouldnt be there.

After much further research, i managed to find a solution.

google.maps.event.addListener(map, 'click', function(event) {
   placeMarker(event.latLng);
});

function placeMarker(location) {
    var marker = new google.maps.Marker({
        position: location, 
        map: map
    });
}

There might be another solution to this:
Your code was:

geom_point(aes(..., show.legend = FALSE))

You can specify the show.legend parameter after the aes call:

geom_point(aes(...), show.legend = FALSE)

then the corresponding legend should disappear

This is just an add-on to the solution in case you want to compute not only unique values but other aggregate functions:

df.groupby(['group']).agg(['min','max','count','nunique'])

Hope you find it useful

The return type depends on the server, sometimes the response is indeed a JSON array but sent as text/plain

Setting the accept headers in the request should get the correct type:

client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json")); 

which can then be serialized to a JSON list or array. Thanks for the comment from @svick which made me curious that it should work.

The Exception I got without configuring the accept headers was System.Net.Http.UnsupportedMediaTypeException.

Following code is cleaner and should work (untested, but works in my case):

    var client = new HttpClient();
    client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
    var response = await client.GetAsync("http://api.usa.gov/jobs/search.json?query=nursing+jobs");
    var model = await response.Content.ReadAsAsync<List<Job>>();

Jupytext allows for such a conversion on the command line, and importantly you can go back again from the script to a notebook (even an executed notebook). See here.

The best solution is:

1. Right click on Computer -> Properties -> Device manager.
2. View -> Show hidden devices.
3. Choose Non-plug and plug drivers -> HTTP -> Disable.
4. Restart your computer.

Sometimes NaNs or null values in data will generate this error with Numpy. If you are ingesting data from say, a CSV file or something like that, and then operating on the data using numpy arrays, the problem could have originated with your data ingest. You could try feeding your code a small set of data with known values, and see if you get the same result.

I'm using a kendo grid and therefore can't change the implementation to a getter method but I want to test around this (mocking the grid) and not test the grid itself. I was using a spy object but this doesn't support property mocking so I do this:

    this.$scope.ticketsGrid = { 
        showColumn: jasmine.createSpy('showColumn'),
        hideColumn: jasmine.createSpy('hideColumn'),
        select: jasmine.createSpy('select'),
        dataItem: jasmine.createSpy('dataItem'),
        _data: []
    } 

It's a bit long winded but it works a treat

May be better for sql2005+ to use:

DELETE TOP (1000)
FROM [MyTab]
WHERE YourConditions

For Sql2000:

DELETE FROM [MyTab]
WHERE YourIdField IN 
(
  SELECT TOP 1000 
    YourIdField 
  FROM [MyTab]
  WHERE YourConditions
)

BUT

If you want to delete specific subset of rows instead of arbitrary subset, you should explicitly specify order to subquery:

DELETE FROM [MyTab]
WHERE YourIdField IN 
(
  SELECT TOP 1000 
    YourIdField 
  FROM [MyTab]
  WHERE YourConditions
  ORDER BY ExplicitSortOrder
)

Thanks tp @gbn for mentioning and demanding the more clear and exact answer.

Two different approaches:

1. Pass in your return values by pointer, and modify them inside the function. You declare your function as void, but it's returning via the values passed in as pointers.
2. Define a struct that aggregates your return values.

I think that #1 is a little more obvious about what's going on, although it can get tedious if you have too many return values. In that case, option #2 works fairly well, although there's some mental overhead involved in making specialized structs for this purpose.

I propose a very simple Test of Code Coupling:

1. Piece A of code is tightly coupled to Piece B of code if there exists any possible modification to the Piece B that would force changes in Piece A in order to keep correctness.

2. Piece A of code is not tightly coupled to Piece B of code if there is no possible modification to the Piece B that would make a change to Piece A necessary.

This will help you to verify how much coupling there is between the pieces of your code. for reasoning on that see this blog post: http://marekdec.wordpress.com/2012/11/14/loose-coupling-tight-coupling-decoupling-what-is-that-all-about/

ubuntu users:

sudo apt-get install libc6-dev

specially ruby developers that have problem installing gem install json -v '1.8.2' on their VMs

And another year later, I can tell you there is another nice answer.

If you don't like the way prototyping works in order to extend on objects/classes, take alook at this: https://github.com/haroldiedema/joii

Quick example code of possibilities (and many more):

var Person = Class({

    username: 'John',
    role: 'Employee',

    __construct: function(name, role) {
        this.username = name;
        this.role = role;
    },

    getNameAndRole: function() {
        return this.username + ' - ' + this.role;
    }

});

var Manager = Class({ extends: Person }, {

  __construct: function(name)
  {
      this.super('__construct', name, 'Manager');
  }

});

var m = new Manager('John');
console.log(m.getNameAndRole()); // Prints: "John - Manager"

As @ J_F answered in the comments, using {r echo = T, results = 'hide'}.

I wanted to expand on their answer - there are great resources you can access to determine all possible options for your chunk and output display - I keep a printed copy at my desk!

You can find them either on the RStudio Website under Cheatsheets (look for the R Markdown cheatsheet and R Markdown Reference Guide) or, in RStudio, navigate to the "Help" tab, choose "Cheatsheets", and look for the same documents there.

Finally to set default chunk options, you can run (in your first chunk) something like the following code if you want most chunks to have the same behavior:

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = T,
                      results = "hide")
```

Later, you can modify the behavior of individual chunks like this, which will replace the default value for just the results option.

```{r analysis, results="markup"}
# code here
```

Simple idea: get the lenght of the longest row, iterate over each column printing the content of a row if it has elements. The below code might have some off-by-one errors as it was coded in a simple text editor.

  int longestRow = 0;
  for (int i = 0; i < array.length; i++) {
    if (array[i].length > longestRow) {
      longestRow = array[i].length;
    }
  }

  for (int j = 0; j < longestRow; j++) {
    for (int i = 0; i < array.length; i++) {
      if(array[i].length > j) {
        System.out.println(array[i][j]);
      }
    }
  }

Maybe placing the jquery.ui.widget.js as second after jquery.ui.core.js.

You need to use

[0].src

to find the source of the iframe and its URL needs to be on the same domain of the parent.

setInterval(refreshMe, 5000);
function refreshMe() {
    $("#currentElement")[0].src = $("#currentElement")[0].src;   
}

Just throwing another solution in the mix...

Try jq, a lightweight and flexible command-line JSON processor:

jq length /tmp/test.json

Prints the length of the array of objects.

When passing a struct to another function, it would usually be better to do as Donnell suggested above and pass it by reference instead.

A very good reason for this is that it makes things easier if you want to make changes that will be reflected when you return to the function that created the instance of it.

Here is an example of the simplest way to do this:

#include <stdio.h>

typedef struct student {
    int age;
} student;

void addStudent(student *s) {
    /* Here we can use the arrow operator (->) to dereference 
       the pointer and access any of it's members: */
    s->age = 10;
}

int main(void) {

    student aStudent = {0};     /* create an instance of the student struct */
    addStudent(&aStudent);      /* pass a pointer to the instance */

    printf("%d", aStudent.age);

    return 0;
}

In this example, the argument for the addStudent() function is a pointer to an instance of a student struct - student *s. In main(), we create an instance of the student struct and then pass a reference to it to our addStudent() function using the reference operator (&).

In the addStudent() function we can make use of the arrow operator (->) to dereference the pointer, and access any of it's members (functionally equivalent to: (*s).age).

Any changes that we make in the addStudent() function will be reflected when we return to main(), because the pointer gave us a reference to where in the memory the instance of the student struct is being stored. This is illustrated by the printf(), which will output "10" in this example.

Had you not passed a reference, you would actually be working with a copy of the struct you passed in to the function, meaning that any changes would not be reflected when you return to main - unless you implemented a way of passing the new version of the struct back to main or something along those lines!

Although pointers may seem off-putting at first, once you get your head around how they work and why they are so handy they become second nature, and you wonder how you ever coped without them!

It is also possible to place the MySQL data directory in a tmpfs in thus speeding up the database write and read calls. It might not be the most efficient way to do this but sometimes you can't just change the storage engine.

Here is my fstab entry for my MySQL data directory

none            /opt/mysql/server-5.6/data  tmpfs   defaults,size=1000M,uid=999,gid=1000,mode=0700          0       0

You may also want to take a look at the innodb_flush_log_at_trx_commit=2 setting. Maybe this will speedup your MySQL sufficently.

innodb_flush_log_at_trx_commit changes the mysql disk flush behaviour. When set to 2 it will only flush the buffer every second. By default each insert will cause a flush and thus cause more IO load.

I needed to kill processes on different ports so I created a bash script:

killPort() {
  PID=$(echo $(lsof -n -i4TCP:$1) | awk 'NR==1{print $11}')
  kill -9 $PID
}

Just add that to your .bashrc and run it like this:

killPort 8080

You can pass whatever port number you wish

Like this:

if(borrar())
{
   // Do something
}

If borrar() returns true then do something (if it is not false).

You can use easy_date to make it easy:

import date_converter
my_date = date_converter.date_to_string(today, '%Y-%m-%d')

Open up the table designer in SQL Server Management Studio (right-click table and select 'Design')

Holding down the Ctrl key highlight two or more columns in the left hand table margin

Hit the little 'Key' on the standard menu bar at the top

You're done..

:-)

This is ridiculous but I just have rebooted my machine (mac) and the problem was gone like it has never happened. I hate to sound like a support guy...

                       int i = Integer.parseInt(one.getText().toString());
                       int j = Integer.parseInt(two.getText().toString());
                  }

              builder.show();

another simple solution is to use fs.readFile instead of using require you can save a text file contaning a json object, and create a interval on the server to reload this object.

pros:

• no need to use external libs
• relevant for production (reloading config file on change)
• easy to implement

cons:

• you can't reload a module - just a json containing key-value data

That particular phrasing is by James Iry, from his highly entertaining Brief, Incomplete and Mostly Wrong History of Programming Languages, in which he fictionally attributes it to Philip Wadler.

The original quote is from Saunders Mac Lane in Categories for the Working Mathematician, one of the foundational texts of Category Theory. Here it is in context, which is probably the best place to learn exactly what it means.

But, I'll take a stab. The original sentence is this:

All told, a monad in X is just a monoid in the category of endofunctors of X, with product × replaced by composition of endofunctors and unit set by the identity endofunctor.

X here is a category. Endofunctors are functors from a category to itself (which is usually all Functors as far as functional programmers are concerned, since they're mostly dealing with just one category; the category of types - but I digress). But you could imagine another category which is the category of "endofunctors on X". This is a category in which the objects are endofunctors and the morphisms are natural transformations.

And of those endofunctors, some of them might be monads. Which ones are monads? Exactly the ones which are monoidal in a particular sense. Instead of spelling out the exact mapping from monads to monoids (since Mac Lane does that far better than I could hope to), I'll just put their respective definitions side by side and let you compare:

A monoid is...

• A set, S
• An operation, • : S × S ? S
• An element of S, e : 1 ? S

...satisfying these laws:

• (a • b) • c = a • (b • c), for all a, b and c in S
• e • a = a • e = a, for all a in S

A monad is...

• An endofunctor, T : X ? X (in Haskell, a type constructor of kind * -> * with a Functor instance)
• A natural transformation, µ : T × T ? T, where × means functor composition (µ is known as join in Haskell)
• A natural transformation, ? : I ? T, where I is the identity endofunctor on X (? is known as return in Haskell)

...satisfying these laws:

• µ ° Tµ = µ ° µT
• µ ° T? = µ ° ?T = 1 (the identity natural transformation)

With a bit of squinting you might be able to see that both of these definitions are instances of the same abstract concept.

You can do EXISTS in Oracle PL/SQL.

You can do the following:

DECLARE
    n_rowExist NUMBER := 0;
BEGIN
    SELECT CASE WHEN EXISTS (
      SELECT 1
      FROM person
      WHERE ID = 10
    ) THEN 1 ELSE 0 INTO n_rowExist END FROM DUAL;
    
    IF n_rowExist = 1 THEN
       -- do things when it exists
    ELSE
       -- do things when it doesn't exist
    END IF;

END;
/

Explanation:

In the query nested where it starts with SELECT CASE WHEN EXISTS and after the parenthesis (SELECT 1 FROM person WHERE ID = 10) it will return a result if it finds a person of ID of 10. If the there's a result on the query then it will assign the value of 1 otherwise it will assign the value of 0 to n_rowExist variable. Afterwards, the if statement checks if the value returned equals to 1 then is true otherwise it will be 0 = 1 and that is false.

inetmgr then come to Application pool->Advanced setting of your pool-> will have the option "Enable 32-Bit Applications" set to true; and restart IIS. check again.!

Using -x test skip test execution but this also exclude test code compilation.

gradle build -x test 

In our case, we have a CI/CD process where one goal is compilation and next goal is testing (Build -> Test).

So, for our first Build goal we wanted to ensure that the whole project compiles well. For this we have used:

./gradlew build testClasses -x test

On the next goal we simply execute tests.

Use the Array#join method (the argument to join is what to insert between the strings - in this case a space):

@arr.join(" ")

With Selenium2Library you can use get_source()

import Selenium2Library
s = Selenium2Library.Selenium2Library()
s.open_browser("localhost:7080", "firefox")
source = s.get_source()

There is sparrow plugin docker-remove-dangling-images you can use to clean up stopped containers and unused (dangling) images:

$ sparrow plg run docker-remove-dangling-images

It works both for Linux and Windows OS.

It surprises me that no one mentioned the key difference between these two is that the temp table supports parallel insert while the table variable doesn't. You should be able to see the difference from the execution plan. And here is the video from SQL Workshops on Channel 9.

This also explains why you should use a table variable for smaller tables, otherwise use a temp table, as SQLMenace answered before.

This helped me to resolve the problem (one line - split for readability / copy-ability):

Rails 6

Rails 6 added an upsert and upsert_all methods that deliver this functionality.

Model.upsert(column_name: value)

[upsert] It does not instantiate any models nor does it trigger Active Record callbacks or validations.

Rails 5, 4, and 3

Not if you are looking for an "upsert" (where the database executes an update or an insert statement in the same operation) type of statement. Out of the box, Rails and ActiveRecord have no such feature. You can use the upsert gem, however.

Otherwise, you can use: find_or_initialize_by or find_or_create_by, which offer similar functionality, albeit at the cost of an additional database hit, which, in most cases, is hardly an issue at all. So unless you have serious performance concerns, I would not use the gem.

For example, if no user is found with the name "Roger", a new user instance is instantiated with its name set to "Roger".

user = User.where(name: "Roger").first_or_initialize
user.email = "[email protected]"
user.save

Alternatively, you can use find_or_initialize_by.

user = User.find_or_initialize_by(name: "Roger")

In Rails 3.

user = User.find_or_initialize_by_name("Roger")
user.email = "[email protected]"
user.save

You can use a block, but the block only runs if the record is new.

User.where(name: "Roger").first_or_initialize do |user|
  # this won't run if a user with name "Roger" is found
  user.save 
end

User.find_or_initialize_by(name: "Roger") do |user|
  # this also won't run if a user with name "Roger" is found
  user.save
end

If you want to use a block regardless of the record's persistence, use tap on the result:

User.where(name: "Roger").first_or_initialize.tap do |user|
  user.email = "[email protected]"
  user.save
end

Note that if you have committed a bunch of changes in various submodules, you can (or will be soon able to) push everything in one go (ie one push from the parent repo), with:

git push --recurse-submodules=on-demand

git1.7.11 ([ANNOUNCE] Git 1.7.11.rc1) mentions:

"git push --recurse-submodules" learned to optionally look into the histories of submodules bound to the superproject and push them out.

Probably done after this patch and the --on-demand option:

--recurse-submodules=<check|on-demand|no>::

Make sure all submodule commits used by the revisions to be pushed are available on a remote tracking branch.

• If check is used, it will be checked that all submodule commits that changed in the revisions to be pushed are available on a remote.
  Otherwise the push will be aborted and exit with non-zero status.
• If on-demand is used, all submodules that changed in the revisions to be pushed will be pushed.
  If on-demand was not able to push all necessary revisions it will also be aborted and exit with non-zero status.

This option only works for one level of nesting. Changes to the submodule inside of another submodule will not be pushed.

Here I get only three specific columns from mainDataTable and use the filter

DataTable checkedParams = mainDataTable.Select("checked = true").CopyToDataTable()
.DefaultView.ToTable(false, "lagerID", "reservePeriod", "discount");

you should put quotes and also, your function declaration is wrong.

myFunction()
{
    echo "$1"
    echo "$2"
    echo "$3"
}

And like the others, it works for me as well. Tell us what version of shell you are using.

remove the config.php file located in bootstrap/cache/ enter link description here

that's works with me

Use sys.stdout.write('Installing XXX... ') and sys.stdout.write('Done'). In this way, you have to add the new line by hand with "\n" if you want to recreate the print functionality. I think that it might be unnecessary to use curses just for this.

Both Date and moment will parse the input string in the local time zone of the browser by default. However Date is sometimes inconsistent with this regard. If the string is specifically YYYY-MM-DD, using hyphens, or if it is YYYY-MM-DD HH:mm:ss, it will interpret it as local time. Unlike Date, moment will always be consistent about how it parses.

The correct way to parse an input moment as UTC in the format you provided would be like this:

moment.utc('07-18-2013', 'MM-DD-YYYY')

Refer to this documentation.

If you want to then format it differently for output, you would do this:

moment.utc('07-18-2013', 'MM-DD-YYYY').format('YYYY-MM-DD')

You do not need to call toString explicitly.

Note that it is very important to provide the input format. Without it, a date like 01-04-2013 might get processed as either Jan 4th or Apr 1st, depending on the culture settings of the browser.

@Ludwig 's solution was brilliant. A couple of fixes (which didn't have to do with operating system, and I couldn't place as a comment on his original posting because this is too long):

1. IE 11 no longer identifies itself as MS IE.
2. Chrome on IOS spoofs itself as Safari

Allow Apache Through the Firewall

Allow the default HTTP and HTTPS port, ports 80 and 443, through firewalld:

sudo firewall-cmd --permanent --add-port=80/tcp
sudo firewall-cmd --permanent --add-port=443/tcp

And reload the firewall:

sudo firewall-cmd --reload

For a dictionary, you're best of encoding to JSON first. You can use simplejson.dumps() or if you want to convert from a data model in App Engine, you could use encode() from the GQLEncoder library.

You save some bytes by avoiding the .attr altogether by passing the properties to the jQuery constructor:

var img = $('<img />',
             { id: 'Myid',
               src: 'MySrc.gif', 
               width: 300
             })
              .appendTo($('#YourDiv'));

Try writing the following batch file and executing it:

Echo one
cmd
Echo two
cmd
Echo three
cmd

Only the first two lines get executed. But if you type "exit" at the command prompt, the next two lines are processed. It's a shell loading another.

To be sure that this is not what is happening in your script, just type "exit" when the first command ends.

HTH!

As others said, an association is a relationship between objects, aggregation and composition are types of association.

From an implementation point of view, an aggregation is obtained by having a class member by reference. For example, if class A aggregates an object of class B, you'll have something like this (in C++):

class A {
    B & element;
  // or B * element;
};

The semantics of aggregation is that when an object A is destroyed, the B object it is storing will still exists. When using composition, you have a stronger relationship, usually by storing the member by value:

class A {
    B element;
};

Here, when an A object is destroyed, the B object it contains will be destroyed too. The easiest way to achieve this is by storing the member by value, but you could also use some smart pointer, or delete the member in the destructor:

class A {
    std::auto_ptr<B> element;
};

class A {
    B * element;

    ~A() {
        delete B;
    }
};

The important point is that in a composition, the container object owns the contained one, whereas in aggregation, it references it.

If you are running iOS 13 or above use this code in your SceneDelegate:

func scene(_ scene: UIScene, willConnectTo session: UISceneSession, options connectionOptions: UIScene.ConnectionOptions) {
    
    guard let notificationResponse = connectionOptions.notificationResponse else { return }
    
    let pushTitle = notificationResponse.notification.request.content.title
    let pushSubtitle = notificationResponse.notification.request.content.subtitle
    let pushBody = notificationResponse.notification.request.content.body
    
    // do your staff here
}

This saves the data in a list of lists.

text = open("filetest.txt", "r")
data = [ ]
for line in text:
    data.append( line.strip().split() )

print "number of lines ", len(data)
print "number of columns ", len(data[0])

print "element in first row column two ", data[0][1]

Here is an example without a parameter: http://en.csharp-online.net/CSharp_FAQ:_How_call_a_method_using_a_name_string

with params: http://www.daniweb.com/forums/thread98148.html#

you basically pass in an array of objects along with name of method. you then use both with the Invoke method.

params Object[] parameters

If you do not like double quotes like me, this will work for you with single quotes:

$value = Input::get('q');
$books = Book::where('name', 'LIKE', '%' . $value . '%')->limit(25)->get();

return view('pages/search/index', compact('books'));

Following up on @plundra's answer, here's the BSD and OS X version:

find . -type f -print0 \
| xargs -0 stat -f "%m %N" \
| sort -rn | head -1 | cut -f2- -d" "

When you parse the JSON representation, it'll become a JavaScript array of objects.

Because of this, you can use the .length property of the JavaScript array to see how many elements are contained, and use a for loop to enumerate it.

I know this is a little old question, but things changed. Laravel isn't that slow. It's, as mentioned, synced folders are slow. However, on Windows 10 I wasn't able to use rsync. I tried both cygwin and minGW. It seems like rsync is incompatible with git for windows's version of ssh.

Here is what worked for me: NFS.

Vagrant docs says:

NFS folders do not work on Windows hosts. Vagrant will ignore your request for NFS synced folders on Windows.

This isn't true anymore. We can use vagrant-winnfsd plugin nowadays. It's really simple to install:

1. Execute vagrant plugin install vagrant-winnfsd
2. Change in your Vagrantfile: config.vm.synced_folder ".", "/vagrant", type: "nfs"
3. Add to Vagrantfile: config.vm.network "private_network", type: "dhcp"

That's all I needed to make NFS work. Laravel response time decreased from 500ms to 100ms for me.

Just issue the sequence of the steps: drop the database, then re-create it again, migrate data, and if you have seeds, sow the database:

rake db:drop db:create db:migrate db:seed

Since the default environment for rake is development, in case if you see the exception in spec tests, you should re-create db for the test environment as follows:

RAILS_ENV=test rake db:drop db:create db:migrate

In most cases the test database is being sowed during the test procedures, so db:seed task action isn't required to be passed. Otherwise, you shall to prepare the database:

rake db:test:prepare

or

RAILS_ENV=test rake db:seed

Additionally, to use the recreate task you can add into Rakefile the following code:

namespace :db do
   task :recreate => [ :drop, :create, :migrate ] do
      if ENV[ 'RAILS_ENV' ] !~ /test|cucumber/
         Rake::Task[ 'db:seed' ].invoke
      end
   end
end

Then issue:

rake db:recreate

Here's a module for calculating SHA1 hashes that is usable for Excel formulas eg. '=SHA1HASH("test")'. To use it, make a new module called 'module_sha1' and copy and paste it all in. This is based on some VBA code from http://vb.wikia.com/wiki/SHA-1.bas, with changes to support passing it a string, and executable from formulas in Excel cells.

You could do this:

String theFirstOne = strz[0];

The javadoc for Collection gives the following caveat wrt ordering of the elements of the array:

If this collection makes any guarantees as to what order its elements are returned by its iterator, this method must return the elements in the same order.

The above answers did not work for me. The below does: document.getElementById("input_field_id").setAttribute("readonly", true);

And to remove the readonly attribute: document.getElementById("input_field_id").removeAttribute("readonly");

And for running when the page is loaded, it is worth referring to here.

Edit: The original link I answered with is now invalid.The newer URL would be https://developers.google.com/web/tools/chrome-devtools/javascript/add-breakpoints#exceptions as of 2016-11-11.

I realize this question has an answer, but it's no longer accurate. Use the link above ^

(link replaced by edited above) - you can now set it to break on all exceptions or just unhandled ones. (Note that you need to be in the Sources tab to see the button.)

Chrome's also added some other really useful breakpoint capabilities now, such as breaking on DOM changes or network events.

Normally I wouldn't re-answer a question, but I had the same question myself, and I found this now-wrong answer, so I figured I'd put this information in here for people who came along later in searching. :)

PHP 5.3 (an I think older versions too) seems to have problem with same name in different cases. So I had this problem when a had the class Login and the interface it implements LogIn. After I renamed LogIn to Log_In the problem got solved.

If you have supporting indexes, and relatively high counts, something like this may be considerably faster than the solutions suggested:

SELECT name, MAX(Rcount) + MAX(Acount) AS TotalCount
FROM (
  SELECT name, COUNT(*) AS Rcount, 0 AS Acount
  FROM Results GROUP BY name
  UNION ALL
  SELECT name, 0, count(*)
  FROM Archive_Results
  GROUP BY name
) AS Both
GROUP BY name
ORDER BY name;

Use console.log(JSON.stringify(result)) to get the JSON in a string format.

EDIT: If your intention is to get the id and other properties from the result object and you want to see it console to know if its there then you can check with hasOwnProperty and access the property if it does exist:

var obj = {id : "007", name : "James Bond"};
console.log(obj);                    // Object { id: "007", name: "James Bond" }
console.log(JSON.stringify(obj));    //{"id":"007","name":"James Bond"}
if (obj.hasOwnProperty("id")){
    console.log(obj.id);             //007
}

The error ShowAllData method of Worksheet class failed usually occurs when you try to remove an applied filter when there is not one applied.

I am not certain if you are trying to remove the whole AutoFilter, or just remove any applied filter, but there are different approaches for each.

To remove an applied filter but leave AutoFilter on:

If ActiveSheet.AutoFilterMode Or ActiveSheet.FilterMode Then
    ActiveSheet.ShowAllData
End If

The rationale behind the above code is to test that there is an AutoFilter or whether a filter has been applied (this will also remove advanced filters).

To completely remove the AutoFilter:

ActiveSheet.AutoFilterMode = False

In the above case, you are simply disabling the AutoFilter completely.

select ID from A where ID not in (select ID from B);

or

select ID from A except select ID from B;

Your second question:

delete from A where ID not in (select ID from B);

In Other ways to get difference between date;

import dateutil.parser
import datetime

timeDifference = current_date - dateutil.parser.parse(last_sent_date)
time_difference_in_minutes = (int(timeDifference.days) * 24 * 60) + int((timeDifference.seconds) / 60)

In my case, it was because I was only catching specific types of exceptions:

try
  {
    get-item -Force -LiteralPath $Path -ErrorAction Stop

    #if file exists
    if ($Path -like '\\*') {$fileType = 'n'}  #Network
    elseif ($Path -like '?:\*') {$fileType = 'l'} #Local
    else {$fileType = 'u'} #Unknown File Type

  }
catch [System.UnauthorizedAccessException] {$fileType = 'i'} #Inaccessible
catch [System.Management.Automation.ItemNotFoundException]{$fileType = 'x'} #Doesn't Exist

Added these to handle additional the exception causing the terminating error, as well as unexpected exceptions

catch [System.Management.Automation.DriveNotFoundException]{$fileType = 'x'} #Doesn't Exist
catch {$fileType='u'} #Unknown

Objects will be passed by reference irrespective of within methods of same class or another class. Here is a modified version of same sample code to help you understand. The value will be changed to 'xyz.'

using System;
using System.Collections.Generic;
using System.Diagnostics;
using System.Linq;
using System.Text;

namespace ConsoleApplication1
{
    public class Employee
    {
        public string Name { get; set; }
    }

    public class MyClass
    {
        public Employee EmpObj;

        public void SetObject(Employee obj)
        {
            EmpObj = obj;
        }
    }

    public class Program
    {
       static void Main(string[] args)
        {
            Employee someTestObj = new Employee();
            someTestObj.Name = "ABC";

            MyClass cls = new MyClass();
            cls.SetObject(someTestObj);

            Console.WriteLine("Changing Emp Name To xyz");
            someTestObj.Name = "xyz";

            Console.WriteLine("Accessing Assigned Emp Name");
            Console.WriteLine(cls.EmpObj.Name); 

           Console.ReadLine();
       }       
    }
 }

Cloning the objects before adding them. For example, instead of newList.addAll(oldList);

for(Person p : oldList) {
    newList.add(p.clone());
}

Assuming clone is correctly overriden inPerson.

Have you instaled the J2EE? If you installed just de standard (J2SE) it won´t find.

Nothing worked until I went this way: Settings>Developer options>Default USB configuration now you can choose your default USB connection purpose.

I had the same issue and couldn't use SVN after the update,

Just in case if doing xcode-select --install didn't fix the issue,

You might see,

svn: error: The subversion command line tools are no longer provided by Xcode.

Refer : https://developer.apple.com/documentation/macos_release_notes/macos_catalina_10_15_release_notes

Try installing the svn by brew

brew install svn

This should get you going.

Try to replace it with °, and also to set the charset to utf-8, as Martin suggests.

°C will get you something like this:

And if you also want the deserialised object to have functions, you could use my small tool: https://github.com/khayll/jsmix

//first you'll need to define your model
var GraphNode = function() {};
GraphNode.prototype.getType = function() {
   return this.$type;
}

var Adjacency = function() {};
Adjacency.prototype.getData =n function() {
    return this.data;
}

//then you could say:
var result = JSMix(jsonData)
    .withObject(GraphNode.prototype, "*")
    .withObject(Adjacency.prototype, "*.adjacencies")
    .build();

//and use them
console.log(result[1][0].getData());

You can use Mockito.isA() for that:

import static org.mockito.Matchers.isA;
import static org.mockito.Mockito.verify;

verify(bar).doStuff(isA(Foo[].class));

http://site.mockito.org/mockito/docs/current/org/mockito/Matchers.html#isA(java.lang.Class)

These queries will also work:

Workaround 1)

SELECT ename, sal 
FROM Emp e1 WHERE n-1 = (SELECT COUNT(DISTINCT sal) 
                         FROM Emp e2 WHERE e2.sal > e1.sal)

Workaround 2) using row_num function.

SELECT * 
FROM ( 
   SELECT e.*, ROW_NUMBER() OVER (ORDER BY sal DESC) rn FROM Emp e 
) WHERE rn = n;

Workaround 3 ) using rownum pseudocolumn

Select MAX(SAL) 
from (
   Select * 
   from (
      Select * 
      from EMP 
      order by SAL Desc
   ) where rownum <= n
)

When you use addEventListener, this will be bound automatically. So if you want a reference to the element on which the event handler is installed, just use this from within your function:

productLineSelect.addEventListener('change',getSelection,false);

function getSelection(){
    var value = sel.options[this.selectedIndex].value;
    alert(value);
}

If you want to pass in some other argument from the context where you call addEventListener, you can use a closure, like this:

productLineSelect.addEventListener('change', function(){ 
    // pass in `this` (the element), and someOtherVar
    getSelection(this, someOtherVar); 
},false);

function getSelection(sel, someOtherVar){
    var value = sel.options[sel.selectedIndex].value;
    alert(value);
    alert(someOtherVar);
}

As the more recent MySQL documentation on view restrictions says:

Before MySQL 5.7.7, subqueries cannot be used in the FROM clause of a view.

This means, that choosing a MySQL v5.7.7 or newer or upgrading the existing MySQL instance to such a version, would remove this restriction on views completely.

However, if you have a current production MySQL version that is earlier than v5.7.7, then the removal of this restriction on views should only be one of the criteria being assessed while making a decision as to upgrade or not. Using the workaround techniques described in the other answers may be a more viable solution - at least on the shorter run.

Typing the following in the terminal will erase your history (meaning using up arrow will get you nothing), but it will not clear the screen:

history -c

Use ArrayList < Map < String, String > >

Here a code sample :

ArrayList<Map<String, String>> products = new ArrayList<Map<String, String>>();
while (iterator.hasNext()) {
         Map<String, String> product = new HashMap<String, String>();
         Element currentProduct = iterator.next();
         product.put("id",currentProduct.get("id"));
         product.put("name" , currentProduct.get("name") );
         products.add(product );
}
System.out.println("products : " + products);

Output :

products : [{id=0001, name=prod1}, {id=0002, name=prod2}]

If you're getting this error on Google Cloud SQL (mysql 5.7 for example) then it's probably not at this time going to be a simple fix as not all InnoDB flags are supported. If you're coming across from Mysql 5.5 as I was (for an old Wordpress setup) this could mean you need to wrangle some column types in the source database before you export.

Some more information can be found here.

Do as below using String#tr :

 "((String1))".tr('()', '')
 # => "String1"

Have you tried the arrange > auto arrange function in MySQL Workbench. It may save you from manually moving the tables around.

Firstly,the crash reason is decorView's index is -1,we can knew it from Android source code ,there is code snippet:

class:android.view.WindowManagerGlobal

file:WindowManagerGlobal.java

private int findViewLocked(View view, boolean required) {
        final int index = mViews.indexOf(view);
//here, view is decorView,comment by OF
        if (required && index < 0) {
            throw new IllegalArgumentException("View=" + view + " not attached to window manager");
        }
        return index;
    }

so we get follow resolution,just judge decorView's index,if it more than 0 then continue or just return and give up dismiss,code as follow:

try {
            Class<?> windowMgrGloable = Class.forName("android.view.WindowManagerGlobal");
            try {
                Method mtdGetIntance = windowMgrGloable.getDeclaredMethod("getInstance");
                mtdGetIntance.setAccessible(true);
                try {
                    Object windownGlobal = mtdGetIntance.invoke(null,null);
                    try {
                        Field mViewField = windowMgrGloable.getDeclaredField("mViews");
                        mViewField.setAccessible(true);
                        ArrayList<View> mViews = (ArrayList<View>) mViewField.get(windownGlobal);
                        int decorViewIndex = mViews.indexOf(pd.getWindow().getDecorView());
                        Log.i(TAG,"check index:"+decorViewIndex);
                        if (decorViewIndex < 0) {
                            return;
                        }
                    } catch (NoSuchFieldException e) {
                        e.printStackTrace();
                    }
                } catch (IllegalAccessException e) {
                    e.printStackTrace();
                } catch (InvocationTargetException e) {
                    e.printStackTrace();
                }
            } catch (NoSuchMethodException e) {
                e.printStackTrace();

Recently, I have seen this problem too. Below, you have my solution:

1. ping github.com, if ping failed. it is DNS error.
2. sudo vim /etc/resolv.conf, the add: nameserver 8.8.8.8 nameserver 8.8.4.4

Or it can be a genuine network issue. Restart your network-manager using sudo service network-manager restart or fix it up

I have just received this error after switching from HTTPS to SSH (for my origin remote). To fix, I simply ran the following command (for each repo):

ssh -T [email protected]

Upon receiving a successful response, I could fetch/push to the repo with ssh.

I took that command from Git's Testing your SSH connection guide, which is part of the greater Connecting to GitHub with with SSH guide.

In 2007 my project successfully used OpenOffice.org's Universal Network Objects (UNO) interface to programmatically generate MS-Word compatible documents (*.doc), as well as corresponding PDF documents, from a Java Web application (a Struts/JSP framework).

OpenOffice UNO also lets you build MS-Office-compatible charts, spreadsheets, presentations, etc. We were able to dynamically build sophisticated Word documents, including charts and tables.

We simplified the process by using template MS-Word documents with bookmark inserts into which the software inserted content, however, you can build documents completely from scratch. The goal was to have the software generate report documents that could be shared and further tweaked by end-users before converting them to PDF for final delivery and archival.

You can optionally produce documents in OpenOffice formats if you want users to use OpenOffice instead of MS-Office. In our case the users want to use MS-Office tools.

UNO is included within the OpenOffice suite. We simply linked our Java app to UNO-related libraries within the suite. An OpenOffice Software Development Kit (SDK) is available containing example applications and the UNO Developer's Guide.

I have not investigated whether the latest OpenOffice UNO can generate MS-Office 2007 Open XML document formats.

The important things about OpenOffice UNO are:

1. It is freeware
2. It supports multiple languages (e.g. Visual Basic, Java, C++, and others).
3. It is platform-independent (Windows, Linux, Unix, etc.).

Here are some useful web sites:

• Open Office home
• Open Office UNO Developer's Guide
• OpenOffice Developer's Forum (especially the "Macros and API" and "Code Snippets" forums).

I think the most important thing to keep in mind is: is the name descriptive enough? Can you tell by looking at the name what the Class is supposed to do? Using words like "Manager", "Service" or "Handler" in your class names can be considered too generic, but since a lot of programmers use them it also helps understanding what the class is for.

I myself have been using the facade-pattern a lot (at least, I think that's what it is called). I could have a User class that describes just one user, and a Users class that keeps track of my "collection of users". I don't call the class a UserManager because I don't like managers in real-life and I don't want to be reminded of them :) Simply using the plural form helps me understand what the class does.

This will never work, because the JS VM has moved on from that async_call and returned the value, which you haven't set yet.

Don't try to fight what is natural and built-in the language behaviour. You should use a callback technique or a promise.

function f(input, callback) {
    var value;

    // Assume the async call always succeed
    async_call(input, function(result) { callback(result) };

}

The other option is to use a promise, have a look at Q. This way you return a promise, and then you attach a then listener to it, which is basically the same as a callback. When the promise resolves, the then will trigger.

There are various use cases of closures.Here, I am going to explain most important usage of Closure concept.

• Closure can be used to create private methods and variables just like an object-oriented language like java, c++ and so on. Once you implemented private methods and variables, your variables defined inside a function won't be accessible by window object. This helps in data hiding and data security.

const privateClass = () => {
  let name = "sundar";
  function setName(changeName) {
    name = changeName;
  }
  function getName() {
    return name;
  }
  return {
    setName: setName,
    getName: getName,
  };
};

let javaLikeObject = privateClass(); \\ similar to new Class() in OOPS.

console.log(javaLikeObject.getName()); \\this will give sundar
javaLikeObject.setName("suresh");
console.log(javaLikeObject.getName()); \\this will give suresh

• Another real-life example of closure :

Create index.html:

<html lang="en">
  <head>
    <meta charset="UTF-8" />
    <meta name="viewport" content="width=device-width, initial-scale=1.0" />
    <title>Program with Javascript</title>
  </head>
  <body>
    <p id="first"></p>
    <p id="second"></p>
    <button onclick="applyingConcepts()">Click</button>
    <script src="./index.js"></script>
  </body>
</html>

2)In index.js:

  let count = 0;
  return () => {
    document.getElementById("first").innerHTML = count++;
  };
})();

• In this example, when you click a button, then your count will be updated on p#id. Note: You might be wondering what's special in this code. When you inspect, you will notice that you can't change the value of count using the window object. This means you have declared private variable count so this prevents your states from being spoiled by the client.

Besides Manuel's way, you can still use the Manifest.

In Android Studio stable, you have to add the following 2 lines to application in the AndroidManifest file:

    android:debuggable="true"
    tools:ignore="HardcodedDebugMode"

The first one will enable debugging of signed APK, and the second one will prevent compile-time error.

After this, you can attach to the process via "Attach debugger to Android process" button.

This one might works for you....

void List<Integer> makeSequence(int begin, int end) {

  AtomicInteger ai=new AtomicInteger(begin);
  List<Integer> ret = new ArrayList(end-begin+1);

  while ( end-->begin) {

    ret.add(ai.getAndIncrement());

  }
  return ret;  
}

Simply, the stack is where local variables get created. Also, every time you call a subroutine the program counter (pointer to the next machine instruction) and any important registers, and sometimes the parameters get pushed on the stack. Then any local variables inside the subroutine are pushed onto the stack (and used from there). When the subroutine finishes, that stuff all gets popped back off the stack. The PC and register data gets and put back where it was as it is popped, so your program can go on its merry way.

The heap is the area of memory dynamic memory allocations are made out of (explicit "new" or "allocate" calls). It is a special data structure that can keep track of blocks of memory of varying sizes and their allocation status.

In "classic" systems RAM was laid out such that the stack pointer started out at the bottom of memory, the heap pointer started out at the top, and they grew towards each other. If they overlap, you are out of RAM. That doesn't work with modern multi-threaded OSes though. Every thread has to have its own stack, and those can get created dynamicly.

Assuming s is non-empty:

Character.isUpperCase(s.charAt(0))

or, as mentioned by divec, to make it work for characters with code points above U+FFFF:

Character.isUpperCase(s.codePointAt(0));

Perhaps you could try to use the of method of the Observable class:

import { Observable } from 'rxjs/Observable';
import 'rxjs/add/observable/of';

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

Using Convert.ChangeType and getting the type to convert from the PropertyInfo.PropertyType.

propertyInfo.SetValue( ship,
                       Convert.ChangeType( value, propertyInfo.PropertyType ),
                       null );

It depends. The System.Timers.Timer has two modes of operation.

If SynchronizingObject is set to an ISynchronizeInvoke instance then the Elapsed event will execute on the thread hosting the synchronizing object. Usually these ISynchronizeInvoke instances are none other than plain old Control and Form instances that we are all familiar with. So in that case the Elapsed event is invoked on the UI thread and it behaves similar to the System.Windows.Forms.Timer. Otherwise, it really depends on the specific ISynchronizeInvoke instance that was used.

If SynchronizingObject is null then the Elapsed event is invoked on a ThreadPool thread and it behaves similar to the System.Threading.Timer. In fact, it actually uses a System.Threading.Timer behind the scenes and does the marshaling operation after it receives the timer callback if needed.

Sending https://invalid_login@hostname works fine everywhere except Safari on Mac (well, not checked Edge but should work there too).

Logout doesn't work in Safari when a user selects 'remember password' in the HTTP Basic Authentication popup. In this case the password is stored in Keychain Access (Finder > Applications > Utilities > Keychain Access (or CMD+SPACE and type "Keychain Access")). Sending https://invalid_login@hostname doesn't affect Keychain Access, so with this checkbox it is not possible to logout on Safari on Mac. At least it is how it works for me.

MacOS Mojave (10.14.6), Safari 12.1.2.

The code below works fine for me in Firefox (73), Chrome (80) and Safari (12). When a user navigates to a logout page the code is executed and drops the credentials.

    //It should return 401, necessary for Safari only
    const logoutUrl = 'https://example.com/logout'; 
    const xmlHttp = new XMLHttpRequest();
    xmlHttp.open('POST', logoutUrl, true, 'logout');
    xmlHttp.send();

Also for some reason Safari doesn't save credentials in the HTTP Basic Authentication popup even when the 'remember password' is selected. The other browsers do this correctly.

git reset --hard make changes, then do

git add -A
git commit --amend --no-edit 

git add -A
git commit --amend -m "commit_message"

git push origin master --force

--force will rewrite that commit you've reseted to in the first step.

Don't do this, because you're about to go against the whole idea of VCS systems and git in particular. The only good method is to create new and delete unneeded branch. See git help branch for info.

If you're using .NET 3.5 or .NET 4, it's easy to create the dictionary using LINQ:

Dictionary<string, ArrayList> result = target.GetComponents()
                                      .ToDictionary(x => x.Key, x => x.Value);

There's no such thing as an IEnumerable<T1, T2> but a KeyValuePair<TKey, TValue> is fine.

Google's Java Library Guava also implements Range:

import com.google.common.collect.Range;

Range<Integer> open = Range.open(1, 5);
System.out.println(open.contains(1)); // false
System.out.println(open.contains(3)); // true
System.out.println(open.contains(5)); // false

Range<Integer> closed = Range.closed(1, 5);
System.out.println(closed.contains(1)); // true
System.out.println(closed.contains(3)); // true
System.out.println(closed.contains(5)); // true

Range<Integer> openClosed = Range.openClosed(1, 5);
System.out.println(openClosed.contains(1)); // false
System.out.println(openClosed.contains(3)); // true
System.out.println(openClosed.contains(5)); // true

The accepted answer is spot on the basic definition of horizontal vs vertical scaling. But unlike the common belief that horizontal scaling of databases is only possible with Cassandra, MongoDB, etc I would like to add that horizontal scaling is also very much possible with any traditional RDMS; that too without using any third party solutions.

I know of many companies, specially SaaS based companies that do this. This is done using simple application logic. You basically take a set of users and divide them over multiple DB servers. So for example, you would typically have a "meta" database/table that would store clients, DB server/connection strings, etc and a table that stores client/server mapping.

Then simply direct requests from each client to the DB server they are mapped to.

Now some may say this is akin to horizontal partitioning and not "true" horizontal scaling and they will be right in some ways. But the end result is that you have scaled your DB over multiple Db servers.

The only difference between the two approaches to horizontal scaling is that one approach (MongoDB, etc) the scaling is done by the DB software itself. In that sense you are "buying" the scaling. In the other approach (for RDBMS horizontal scaling), the scaling is built by application code/logic.

Inspired by the insightful answers on this page, I created a mixed approach, which I consider the simplest and more flexible one. What do you think?

First, I define the usage in a variable, which allows me to reuse it in different contexts. The format is very simple, almost WYSIWYG, without the need to add any control characters. This seems reasonably portable to me (I ran it on MacOS and Ubuntu)

__usage="
Usage: $(basename $0) [OPTIONS]

Options:
  -l, --level <n>              Something something something level
  -n, --nnnnn <levels>         Something something something n
  -h, --help                   Something something something help
  -v, --version                Something something something version
"

Then I can simply use it as

echo "$__usage"

or even better, when parsing parameters, I can just echo it there in a one-liner:

levelN=${2:?"--level: n is required!""${__usage}"}

Depending on what you want the file to contain:

• touch /path/to/file for an empty file

• somecommand > /path/to/file for a file containing the output of some command.

    eg: grep --help > randomtext.txt
        echo "This is some text" > randomtext.txt
  

• nano /path/to/file or vi /path/to/file (or any other editor emacs,gedit etc)
  It either opens the existing one for editing or creates & opens the empty file to enter, if it doesn't exist

Create the file using cat

$ cat > myfile.txt

Now, just type whatever you want in the file:

Hello World!

CTRL-D to save and exit

There are several possible solutions:

Create an empty file

touch file

>file

echo -n > file

printf '' > file

The echo version will work only if your version of echo supports the -n switch to suppress newlines. This is a non-standard addition. The other examples will all work in a POSIX shell.

Create a file containing a newline and nothing else

echo '' > file

printf '\n' > file

This is a valid "text file" because it ends in a newline.

Write text into a file

"$EDITOR" file

echo 'text' > file

cat > file <<END \
text
END

printf 'text\n' > file

These are equivalent. The $EDITOR command assumes that you have an interactive text editor defined in the EDITOR environment variable and that you interactively enter equivalent text. The cat version presumes a literal newline after the \ and after each other line. Other than that these will all work in a POSIX shell.

Of course there are many other methods of writing and creating files, too.

The problem must be with the value Model.Id which is null. You can confirm by assigning a value, e.g

@{         
     var blogPostId = 1;          
 }

If the error disappers, then u need to make sure that your model Id has a value before passing it to the view

I got it resolved by doing Repir on .NET framework Extended, in Add/Remove program ;

Using win2008R2, .NET framework 4.0

Loop through elements in the list and update the total like this:

def sum(a):
    total = 0
    index = 0
    while index < len(a):
        total = total + a[index]
        index = index + 1
    return total

You should include <string.h> (or its C++ equivalent, <cstring>).

If you use androidx.appcompat:appcompat and want a custom drawable (of type selector with android:state_checked) to work on old platform versions in addition to new platform versions, you need to use

    <CheckBox
        app:buttonCompat="@drawable/..."

instead of

    <CheckBox
        android:button="@drawable/..."

Bash

To get list of keys in Bash, follow the these steps.

First, define the following wrapper function to make it simple to use (copy and paste into shell):

function memcmd() {
  exec {memcache}<>/dev/tcp/localhost/11211
  printf "%s\n%s\n" "$*" quit >&${memcache}
  cat <&${memcache}
}

Memcached 1.4.31 and above

You can use lru_crawler metadump all command to dump (most of) the metadata for (all of) the items in the cache.

As opposed to cachedump, it does not cause severe performance problems and has no limits on the amount of keys that can be dumped.

Example command by using the previously defined function:

memcmd lru_crawler metadump all

See: ReleaseNotes1431.

Memcached 1.4.30 and below

Get list of slabs by using items statistics command, e.g.:

memcmd stats items

For each slub class, you can get list of items by specifying slub id along with limit number (0 - unlimited):

memcmd stats cachedump 1 0
memcmd stats cachedump 2 0
memcmd stats cachedump 3 0
memcmd stats cachedump 4 0
...

^{Note: You need to do this for each memcached server.}

To list all the keys from all stubs, here is the one-liner (per one server):

for id in $(memcmd stats items | grep -o ":[0-9]\+:" | tr -d : | sort -nu); do
    memcmd stats cachedump $id 0
done

^{Note: The above command could cause severe performance problems while accessing the items, so it's not advised to run on live.}

Notes:

stats cachedump only dumps the HOT_LRU (IIRC?), which is managed by a background thread as activity happens. This means under a new enough version which the 2Q algo enabled, you'll get snapshot views of what's in just one of the LRU's.

If you want to view everything, lru_crawler metadump 1 (or lru_crawler metadump all) is the new mostly-officially-supported method that will asynchronously dump as many keys as you want. you'll get them out of order but it hits all LRU's, and unless you're deleting/replacing items multiple runs should yield the same results.

If you're using Intellij on Mac, this setup finally worked for me.

Installations: Intellij

1. Go to Preferences, search for Plugins.
2. Type "Lombok" in the plugin search box. Lombok is a non-bundled plugin, so it won't show at first.
3. Click "Browse" to search for non-bundled plugins
4. The "Lombok Plugin" should show up. Select it.
5. Click the green "Install" button.
6. Click the "Restart Intellij IDEA" button.

Settings:

1. Enable Annotation processor

   • Go to Preferences -> Build, Execution,Deployment -->Preferences -> Compiler -> Annotation Processors
   • File -> Other Settings -> Default Settings -> Compiler -> Annotation Processors

2. Check if Lombok plugin is enabled

   • IntelliJ IDEA-> Preferences -> Other Settings -> Lombok plugin -> Enable Lombok

3. Add Lombok jar in Global Libraries and project dependencies.

   • File --> Project Structure --> Global libraries (Add lombok.jar)

4. File --> Project Structure --> Project Settings --> Modules --> Dependencies Tab = check lombok

5. Restart Intellij

I might suggest this, as a more gracefully degrading solution, using preventDefault:

$('a').click(function(e) {
    e.preventDefault();  //stop the browser from following
    window.location.href = 'uploads/file.doc';
});

<a href="no-script.html">Download now!</a>

Even if there's no Javascript, at least this way the user will get some feedback.

1. $() means: "first evaluate this, and then evaluate the rest of the line".

   Ex :

   echo $(pwd)/myFile.txt
   

   will be interpreted as

   echo /my/path/myFile.txt
   

   On the other hand ${} expands a variable.

   Ex:

   MY_VAR=toto
   echo ${MY_VAR}/myFile.txt
   

   will be interpreted as

   echo toto/myFile.txt
   

2. Why can't I use it as bash$ while ((i=0;i<10;i++)); do echo $i; done

   I'm afraid the answer is just that the bash syntax for while just isn't the same as the syntax for for.

In TextMate with the mouse: start a selection and keep alt pressed while you move the cursor.

Without the mouse: first select normally using ? and arrows then hit alt and move the cursor.

When you do the second one, you're making a new arraylist, you're not trying to pretend the other list is an arraylist.

I mean, what if the original list is implemented as a linkedlist, or some custom list? You won't know. The second approach is preferred if you really need to make an arraylist from the result. But you can just leave it as a list, that's one of the best advantages of using Interfaces!

I got the solution . I tried this .

<?php $image = wp_get_attachment_image_src( get_post_thumbnail_id( $loop->post->ID ), 'single-post-thumbnail' );?>

    <img src="<?php  echo $image[0]; ?>" data-id="<?php echo $loop->post->ID; ?>">

Much nicer than all this socket or shell madness is simply using sysfs for this:

the file /sys/class/net/eth0/address carries your mac adress as simple string you can read with fopen()/fscanf()/fclose(). Nothing easier than that.

And if you want to support other network interfaces than eth0 (and you probably want), then simply use opendir()/readdir()/closedir() on /sys/class/net/.

This is the simple example to use both of them:

import {
  Directive, HostListener, HostBinding
}
from '@angular/core';

@Directive({
  selector: '[Highlight]'
})
export class HighlightDirective {
  @HostListener('mouseenter') mouseover() {
    this.backgroundColor = 'green';
  };

  @HostListener('mouseleave') mouseleave() {
    this.backgroundColor = 'white';
  }

  @HostBinding('style.backgroundColor') get setColor() {
     return this.backgroundColor;
  };

  private backgroundColor = 'white';
  constructor() {}

}

Introduction:

1. HostListener can bind an event to the element.

2. HostBinding can bind a style to the element.

3. this is directive, so we can use it for

   Some Text

4. So according to the debug, we can find that this div has been binded style = "background-color:white"

   Some Text

5. we also can find that EventListener of this div has two event: mouseenter and mouseleave. So when we move the mouse into the div, the colour will become green, mouse leave, the colour will become white.

As already mentioned, Chrome Extensions don't allow to have inline JavaScript due to security reasons so you can try this workaround as well.

HTML file

<!doctype html>
    <html>
        <head>
            <title>
                Getting Started Extension's Popup
            </title>
            <script src="popup.js"></script>
        </head>
        <body>
            <div id="text-holder">ha</div><br />
            <a class="clickableBtn">
                  hyhy
            </a>
        </body>
    </html>
<!doctype html>

popup.js

window.onclick = function(event) {
    var target = event.target ;
    if(target.matches('.clickableBtn')) {
        var clickedEle = document.activeElement.id ;
        var ele = document.getElementById(clickedEle);
        alert(ele.text);
    }
}

Or if you are having a Jquery file included then

window.onclick = function(event) {
    var target = event.target ;
    if(target.matches('.clickableBtn')) {
        alert($(target).text());
    }
}

Suppose we have three anchor tags like ,

<a  href="ID=1" class="testClick">Test1.</a>
<br />
<a  href="ID=2" class="testClick">Test2.</a>
<br />
<a  href="ID=3" class="testClick">Test3.</a>

now in script

$(".testClick").click(function () {
        var anchorValue= $(this).attr("href");
        alert(anchorValue);
});

use this keyword instead of className (testClick)

You can minify all your scripts in page, including analytics.js using:

• Some server-side technology (https://github.com/matthiasmullie/minify)
• External service (http://www.cloudflare.com)

Remember to minify the files before using it. Otherwise it will consume more processing time.

This one is working for me for settings environment variable for the test plugin

test {
    systemProperties = [
        'catalina.home': 'c:/test'
    ]
    println "Starting Tests"
    beforeTest { descriptor ->
       logger.lifecycle("Running test: " + descriptor)                
    }    
}

simple structure, easily adaptable, easy maintenance.

std::string stringIn = "my,csv,,is 10233478,separated,by commas";
std::vector<std::string> commaSeparated(1);
int commaCounter = 0;
for (int i=0; i<stringIn.size(); i++) {
    if (stringIn[i] == ",") {
        commaSeparated.push_back("");
        commaCounter++;
    } else {
        commaSeparated.at(commaCounter) += stringIn[i];
    }
}

in the end you will have a vector of strings with every element in the sentence separated by spaces. empty strings are saved as separate items.
