Try adding this:

$.ajax({
    url: "ajax.aspx",
    type:'get',
    data: {ajaxid:4, UserID: UserID , EmailAddress: encodeURIComponent(EmailAddress)},
    dataType: 'json',
    success: function(response) {
      //Do Something
    },
    error: function(xhr) {
    //Do Something to handle error
    }
});

Depends on what datatype is expected, you can assign html, json, script, xml

It's not 100% clear from the code example, but if the list initial_parameters_of_hypothesis_function is a list of tf.Variable objects, then the line session.run(init) will fail because TensorFlow isn't (yet) smart enough to figure out the dependencies in variable initialization. To work around this, you should change the loop that creates parameters to use initial_parameters_of_hypothesis_function[i].initialized_value(), which adds the necessary dependency:

parameters = []
for i in range(0, number_of_attributes, 1):
    parameters.append(tf.Variable(
        initial_parameters_of_hypothesis_function[i].initialized_value()))

If anyone has how-tos or articles on this, I'd be more than happy to update.

try setting the body style to:

it worked for me

Update: The JSESSIONID stuff here is only for older containers. Please use jt's currently accepted answer unless you are using < Tomcat 6.0.19 or < Tomcat 5.5.28 or another container that does not support HttpOnly JSESSIONID cookies as a config option.

When setting cookies in your app, use

response.setHeader( "Set-Cookie", "name=value; HttpOnly");

However, in many webapps, the most important cookie is the session identifier, which is automatically set by the container as the JSESSIONID cookie.

If you only use this cookie, you can write a ServletFilter to re-set the cookies on the way out, forcing JSESSIONID to HttpOnly. The page at http://keepitlocked.net/archive/2007/11/05/java-and-httponly.aspx http://alexsmolen.com/blog/?p=16 suggests adding the following in a filter.

if (response.containsHeader( "SET-COOKIE" )) {
  String sessionid = request.getSession().getId();
  response.setHeader( "SET-COOKIE", "JSESSIONID=" + sessionid 
                      + ";Path=/<whatever>; Secure; HttpOnly" );
} 

but note that this will overwrite all cookies and only set what you state here in this filter.

If you use additional cookies to the JSESSIONID cookie, then you'll need to extend this code to set all the cookies in the filter. This is not a great solution in the case of multiple-cookies, but is a perhaps an acceptable quick-fix for the JSESSIONID-only setup.

Please note that as your code evolves over time, there's a nasty hidden bug waiting for you when you forget about this filter and try and set another cookie somewhere else in your code. Of course, it won't get set.

This really is a hack though. If you do use Tomcat and can compile it, then take a look at Shabaz's excellent suggestion to patch HttpOnly support into Tomcat.

You can also use sqlcmd mode for this (enable this on the "Query" menu in Management Studio).

:setvar dbname "TEST" 

CREATE DATABASE $(dbname)
GO
ALTER DATABASE $(dbname) SET COMPATIBILITY_LEVEL = 90
GO
ALTER DATABASE $(dbname) SET RECOVERY SIMPLE 
GO

EDIT:

Check this MSDN article to set parameters via the SQLCMD tool.

This seems to be the fastest solution I could come up with, and is faster than os.walk and a lot faster than any glob solution.

• It will also give you a list of all nested subfolders at basically no cost.
• You can search for several different extensions.
• You can also choose to return either full paths or just the names for the files by changing f.path to f.name (do not change it for subfolders!).

Args: dir: str, ext: list.
Function returns two lists: subfolders, files.

See below for a detailed speed anaylsis.

def run_fast_scandir(dir, ext):    # dir: str, ext: list
    subfolders, files = [], []

    for f in os.scandir(dir):
        if f.is_dir():
            subfolders.append(f.path)
        if f.is_file():
            if os.path.splitext(f.name)[1].lower() in ext:
                files.append(f.path)


    for dir in list(subfolders):
        sf, f = run_fast_scandir(dir, ext)
        subfolders.extend(sf)
        files.extend(f)
    return subfolders, files


subfolders, files = run_fast_scandir(folder, [".jpg"])

In case you need the file size, you can also create a sizes list and add f.stat().st_size like this for a display of MiB:

sizes.append(f"{f.stat().st_size/1024/1024:.0f} MiB")

Speed analysis

for various methods to get all files with a specific file extension inside all subfolders and the main folder.

tl;dr:

• fast_scandir clearly wins and is twice as fast as all other solutions, except os.walk.
• os.walk is second place slighly slower.
• using glob will greatly slow down the process.
• None of the results use natural sorting. This means results will be sorted like this: 1, 10, 2. To get natural sorting (1, 2, 10), please have a look at https://stackoverflow.com/a/48030307/2441026

fast_scandir    took  499 ms. Found files: 16596. Found subfolders: 439
os.walk         took  589 ms. Found files: 16596
find_files      took  919 ms. Found files: 16596
glob.iglob      took  998 ms. Found files: 16596
glob.glob       took 1002 ms. Found files: 16596
pathlib.rglob   took 1041 ms. Found files: 16596
os.walk-glob    took 1043 ms. Found files: 16596

Tests were done with W7x64, Python 3.8.1, 20 runs. 16596 files in 439 (partially nested) subfolders.
find_files is from https://stackoverflow.com/a/45646357/2441026 and lets you search for several extensions.
fast_scandir was written by myself and will also return a list of subfolders. You can give it a list of extensions to search for (I tested a list with one entry to a simple if ... == ".jpg" and there was no significant difference).

See my UPDATE at the end, before reading the following answer.

I have windows 8 and another pc with windows 8.1

I had License error saying "Prerelease software. License expired".

The only solution that I found which is inspired by the above solutions (Thanks!) was to run process monitor and see the exact registry keys that are accessed when I start the VS2013 which were:

HKCR\Licenses\E79B3F9C-6543-4897-BBA5-5BFB0A02BB5C

like what are mentioned in the previous posts. However the process monitor said that this registry is access denied.

So I opened regedit and found that registry key and I could not open it. It says I have no permission to see it.

SO I had to change its permission:

1. Right click on the "HKCR\Licenses\E79B3F9C-6543-4897-BBA5-5BFB0A02BB5C" key
2. Permissions
3. Add
4. In "Enter object names to select" I have added my windows user name. Ok.
5. check on Full control
6. Advanced
7. Owner click on "Change"
8. In "Enter object names to select" I have added my windows user name. Ok.
9. Ok. Ok. Ok.

I found that this registry key has several sub keys, however you have to restart regedit to see them.

By seeing which other registry keys are access denied in process monitor , I knew that VS2013 will specifically deal with these subkeys which are ACCESS DENIED also: 06181 0bcad

and these subkeys should be changed their permissions as well like above.

After making these permission changes everything worked well.

The same thing has been done to Microsoft visual studio 2010 because an error in the license as well and the solution worked well.

UPDATE : It turned out that starting visual studio as administrator solved this issue without this registry massage. Seems that this happened to my pc after changing the 'required password to login' removed in the user settings. (I wanted to let the pc start running without any password after restart from a crash or anything else). This made a lot of programs not able to write into some folders like temp folders unless I start the application as admin. Even printing from excel would not work, if excel is not started as admin.

I have used JMF on a videoconference application and it worked well on two laptops: one with integrated webcam and another with an old USB webcam. It requires JMF being installed and configured before-hand, but once you're done you can access the hardware via Java code fairly easily.

Here a simple one liners to check if only one parameter is given otherwise exit the script:

[ "$#" -ne 1 ] && echo "USAGE $0 <PARAMETER>" && exit

Try to set response dataType property directly:

dataType: 'text'

and put

die(''); 

in the end of your php file. You've got error callback cause jquery cannot parse your response. In anyway, you may use a "complete:" callback, just to make sure your request has been processed.

The href property sets or returns the value of the href attribute of a link.

  var hello = domains[i].getElementsByTagName('a')[0].getAttribute('href');
    var url="https://www.google.com/";
    console.log( url+hello);

If you want to achieve sorting where "ä" comes after "a" and is not treated as the same, then you can use a function like mine.

You can always change the alphabet to get different or even weird sortings. However, if you want some letters to be equivalent, then you have to manipulate the strings like a = a.replace(/ä/, 'a') or similar, as many have already replied above. I've included the uppercase letters if someone wants to have all uppercase words before all lowercase words (then you have to ommit .toLowerCase()).

function sortbyalphabet(a,b) {
        alphabet = "0123456789AaÀàÁáÂâÃãÄäBbCcÇçDdÈèÉéÊêËëFfGgHhÌìÍíÎîÏïJjKkLlMmNnÑñOoÒòÓóÔôÕõÖöPpQqRrSsTtÙùÚúÛûÜüVvWwXxÝýŸÿZz";
        a = a.toLowerCase();
        b = b.toLowerCase();
        shorterone = (a.length > b.length ? a : b);
        for (i=0; i<shorterone.length; i++){
            diff = alphabet.indexOf(a.charAt(i)) - alphabet.indexOf(b.charAt(i));
            if (diff!=0){
                return diff;
            }
        }
        // sort the shorter first
        return a.length - b.length;
    }
    var n = ["ast", "Äste", "apfel", "äpfel", "à"];
    console.log(n.sort(sortbyalphabet));
    // should return ["apfel", "ast", "à", "äpfel", "äste"]

You need to use -I with each directory. But you can still delimit the directories with whitespace if you use (GNU) make's foreach:

INC=$(DIR1) $(DIR2) ...
INC_PARAMS=$(foreach d, $(INC), -I$d)

SELECT DATE_ADD(CURDATE(), INTERVAL 2 DAY)

I get the code to generate the PDF from html template :

            # Render HTML into memory and get the template firstly
            template_file_loc = os.path.join(os.path.dirname(__file__), os.pardir, 'templates', 'the_template_pdf_generator.html')
            template_contents = read_all_as_str(template_file_loc)
            render_template = Template(template_contents)

            #rendering_map is the dict for params in the template 
            render_definition = Context(rendering_map)
            render_output = render_template.render(render_definition)

            # Using Rendered HTML to generate PDF
            response = HttpResponse(content_type='application/pdf')

            contents = handler.read()

BigInteger has a constructor where you can pass string as an argument.

try below,

private void sum(String newNumber) {
    // BigInteger is immutable, reassign the variable:
    this.sum = this.sum.add(new BigInteger(newNumber));
}

I prefer onKeyUp since it only fires when the key is released. onKeyDown, on the other hand, will fire multiple times if for some reason the user presses and holds the key. For example, when listening for "pressing" the Enter key to make a network request, you don't want that to fire multiple times since it can be expensive.

// handler could be passed as a prop
<input type="text" onKeyUp={handleKeyPress} />

handleKeyPress(e) {
if (e.key === 'Enter') {
  // do whatever
}

}

Also, stay away from keyCode since it will be deprecated some time.

The error is not refering to myfunction but to start.

I use the opportunity of this question to advise you about an known anti pattern using await which is : return await.

WRONG

async function myfunction() {_x000D_
  console.log('Inside of myfunction');_x000D_
}_x000D_
_x000D_
// Here we wait for the myfunction to finish_x000D_

_x000D_
// useless async here_x000D_
async function start() {_x000D_
  // useless await here_x000D_

(async() => {_x000D_

_x000D_
  await start();_x000D_
  _x000D_
  console.log('after start');_x000D_
})();

CORRECT

async function myfunction() {_x000D_
  console.log('Inside of myfunction');_x000D_

_x000D_
// Here we wait for the myfunction to finish_x000D_

// It's useless to wait the myfunction to finish before to return_x000D_
// we can simply returns a promise that will be resolved later_x000D_
_x000D_
// Also point that we don't use async keyword on the function because_x000D_
// we can simply returns the promise returned by myfunction_x000D_
function start() {_x000D_
  return myfunction();_x000D_
}_x000D_
_x000D_
// Call start_x000D_
(async() => {_x000D_

_x000D_
  await start();_x000D_
  _x000D_
  console.log('after start');_x000D_
})();

Also, know that there is a special case where return await is correct and important : (using try/catch)

Are there performance concerns with `return await`?

Add android:exported="true" in your 'com.example.lib.MainActivity' activity tag.

From the android:exported documentation,

android:exported Whether or not the activity can be launched by components of other applications — "true" if it can be, and "false" if not. If "false", the activity can be launched only by components of the same application or applications with the same user ID.

From your logcat output, clearly a mismatch in uid is causing the issue. So adding the android:exported="true" should do the trick.

In slim markdown use this:

markdown:
  {:.cool-heading}
  #Some Title

Translates to:

<h1 class="cool-heading">Some Title</h1>

This post is old and probably solved but I had the same issue. I resolved it by creating a view of the original table specifying the new column order.

From here I could either use the view or create a new table from the view.

    CREATE VIEW original_tab_vw AS
    SELECT a.col1, a.col3, a.col4, a.col2
    FROM original_tab a
    WHERE a.col1 IS NOT NULL --or whatever

    SELECT * INTO new_table FROM original_tab_vw

Rename or drop the original table and set the name of the new table to the old table.

Check that all your bundle resources are copied in build phase.

Both works. Instead of == you can write eq

After you correct the possible dmp file problem, this is a way to ensure that the schema is remapped and imported appropriately. This will also ensure that the tablespace will change also, if needed:

impdp system/<password> SCHEMAS=user1 remap_schema=user1:user2 \
            remap_tablespace=user1:user2 directory=EXPORTDIR \
            dumpfile=user1.dmp logfile=E:\Data\user1.log

EXPORTDIR must be defined in oracle as a directory as the system user

create or replace directory EXPORTDIR as 'E:\Data';
grant read, write on directory EXPORTDIR to user2;

Another thing to note is that if you want a absolute element to be confined to a parent element then you need to set the parent element's position to relative. That will keep the child element contained within the parent element and it won't be "relative" to the entire window.

I wrote a blog post that gives a simple example that creates the following affect:

That has a green div that is absolutely positioned to the bottom of the parent yellow div.

ActivityManager activityManager = (ActivityManager) context.getSystemService(ACTIVITY_SERVICE);
MemoryInfo memoryInfo = new ActivityManager.MemoryInfo();
activityManager.getMemoryInfo(memoryInfo);

Log.i(TAG, " memoryInfo.availMem " + memoryInfo.availMem + "\n" );
Log.i(TAG, " memoryInfo.lowMemory " + memoryInfo.lowMemory + "\n" );
Log.i(TAG, " memoryInfo.threshold " + memoryInfo.threshold + "\n" );

List<RunningAppProcessInfo> runningAppProcesses = activityManager.getRunningAppProcesses();

Map<Integer, String> pidMap = new TreeMap<Integer, String>();
for (RunningAppProcessInfo runningAppProcessInfo : runningAppProcesses)
{
    pidMap.put(runningAppProcessInfo.pid, runningAppProcessInfo.processName);
}

Collection<Integer> keys = pidMap.keySet();

for(int key : keys)
{
    int pids[] = new int[1];
    pids[0] = key;
    android.os.Debug.MemoryInfo[] memoryInfoArray = activityManager.getProcessMemoryInfo(pids);
    for(android.os.Debug.MemoryInfo pidMemoryInfo: memoryInfoArray)
    {
        Log.i(TAG, String.format("** MEMINFO in pid %d [%s] **\n",pids[0],pidMap.get(pids[0])));
        Log.i(TAG, " pidMemoryInfo.getTotalPrivateDirty(): " + pidMemoryInfo.getTotalPrivateDirty() + "\n");
        Log.i(TAG, " pidMemoryInfo.getTotalPss(): " + pidMemoryInfo.getTotalPss() + "\n");
        Log.i(TAG, " pidMemoryInfo.getTotalSharedDirty(): " + pidMemoryInfo.getTotalSharedDirty() + "\n");
    }
}

Why isn't the PID mapped to the result in activityManager.getProcessMemoryInfo()? Clearly you want to make the resulting data meaningful, so why has Google made it so difficult to correlate the results? The current system doesn't even work well if I want to process the entire memory usage since the returned result is an array of android.os.Debug.MemoryInfo objects, but none of those objects actually tell you what pids they are associated with. If you simply pass in an array of all pids, you will have no way to understand the results. As I understand it's use, it makes it meaningless to pass in more than one pid at a time, and then if that's the case, why make it so that activityManager.getProcessMemoryInfo() only takes an int array?

This is pretty simple with numpy, just subtract the arrays:

diffs = array1 - array2

I get:

diffs == array([ 0.1,  0.2,  0.3])

MacVim is just Vim. Anything you are used to do in Vim will work exactly the same way in MacVim.

MacVim is more integrated in the whole OS than Vim in the Terminal or even GVim in Linux, it follows a lot of Mac OS X's conventions.

If you work mainly with GUI apps (YummyFTP + GitX + Charles, for example) you may prefer MacVim.

If you work mainly with CLI apps (ssh + svn + tcpdump, for example) you may prefer vim in the terminal.

Entering and leaving one realm (CLI) for the other (GUI) and vice-versa can be "expensive".

I use both MacVim and Vim depending on the task and the context: if I'm in CLI-land I'll just type vim filename and if I'm in GUI-land I'll just invoke Quicksilver and launch MacVim.

When I switched from TextMate I kind of liked the fact that MacVim supported almost all of the regular shortcuts Mac users are accustomed to. I added some of my own, mimiking TextMate but, since I was working in multiple environments I forced my self to learn the vim way. Now I use both MacVim and Vim almost exactly the same way. Using one or the other is just a question of context for me.

Also, like El Isra said, the default vim (CLI) in OS X is slightly outdated. You may install an up-to-date version via MacPorts or you can install MacVim and add an alias to your .profile:

alias vim='/path/to/MacVim.app/Contents/MacOS/Vim'

to have the same vim in MacVim and Terminal.app.

Another difference is that many great colorschemes out there work out of the box in MacVim but look terrible in the Terminal.app which only supports 8 colors (+ highlights) but you can use iTerm — which can be set up to support 256 colors — instead of Terminal.

So… basically my advice is to just use both.

EDIT: I didn't try it but the latest version of Terminal.app (in 10.7) is supposed to support 256 colors. I'm still on 10.6.x at work so I'll still use iTerm2 for a while.

EDIT: An even better way to use MacVim's CLI executable in your shell is to move the mvim script bundled with MacVim somewhere in your $PATH and use this command:

$ mvim -v

EDIT: Yes, Terminal.app now supports 256 colors. So if you don't need iTerm2's advanced features you can safely use the default terminal emulator.

If your file looks like this:

[
    {
        "firstname": "toto",
        "lastname": "titi"
    },
    {
        "firstname": "toto2",
        "lastname": "titi2"
    },
]

You can do:

import json from './json/data.json';
// ....
json.forEach(x => { console.log(x.firstname, x.lastname); });

If both data frames have the same column names then you should add one data frame inside ggplot() call and also name x and y values inside aes() of ggplot() call. Then add first geom_line() for the first line and add second geom_line() call with data=df2 (where df2 is your second data frame). If you need to have lines in different colors then add color= and name for eahc line inside aes() of each geom_line().

df1<-data.frame(x=1:10,y=rnorm(10))
df2<-data.frame(x=1:10,y=rnorm(10))

ggplot(df1,aes(x,y))+geom_line(aes(color="First line"))+
  geom_line(data=df2,aes(color="Second line"))+
  labs(color="Legend text")

I think what you are trying to convey can be achieved through multiprocessing. However if you want to do it through threads you can do this. This might help

from threading import Thread
import time

def func1():
    print 'Working'
    time.sleep(2)

def func2():
    print 'Working'
    time.sleep(2)

th = Thread(target=func1)
th.start()
th1=Thread(target=func2)
th1.start()

When We Add First Fragment --> Second Fragment using add() method

 btn_one.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getActivity(),"Click First 
Fragment",Toast.LENGTH_LONG).show();

                Fragment fragment = new SecondFragment();
                getActivity().getSupportFragmentManager().beginTransaction()
                        .add(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();
//                        .replace(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();

            }
        });

When we use add() in fragment

E/Keshav SecondFragment: onAttach
E/Keshav SecondFragment: onCreate
E/Keshav SecondFragment: onCreateView
E/Keshav SecondFragment: onActivityCreated
E/Keshav SecondFragment: onStart
E/Keshav SecondFragment: onResume

When we use replace() in fragment

going to first fragment to second fragment in First -->Second using replace() method

 btn_one.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                Toast.makeText(getActivity(),"Click First Fragment",Toast.LENGTH_LONG).show();

                Fragment fragment = new SecondFragment();
                getActivity().getSupportFragmentManager().beginTransaction()
//                        .add(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();
                        .replace(R.id.fragment_frame, fragment, fragment.getClass().getSimpleName()).addToBackStack(null).commit();

            }
        });

E/Keshav SecondFragment: onAttach
E/Keshav SecondFragment: onCreate

E/Keshav FirstFragment: onPause -------------------------- FirstFragment
E/Keshav FirstFragment: onStop --------------------------- FirstFragment
E/Keshav FirstFragment: onDestroyView -------------------- FirstFragment

E/Keshav SecondFragment: onCreateView
E/Keshav SecondFragment: onActivityCreated
E/Keshav SecondFragment: onStart
E/Keshav SecondFragment: onResume

In case of Replace First Fragment these method is extra called ( onPause,onStop,onDestroyView is extra called )

E/Keshav FirstFragment: onPause

E/Keshav FirstFragment: onStop

E/Keshav FirstFragment: onDestroyView

In case this can help anyone, here's simple CSS as a jumping off point. Turns it into a basic rounded square big enough for thumbs with a toggled background color.

input[type='checkbox'] {_x000D_
    -webkit-appearance:none;_x000D_
    width:30px;_x000D_
    height:30px;_x000D_
    background:white;_x000D_
    border-radius:5px;_x000D_
    border:2px solid #555;_x000D_
}_x000D_
input[type='checkbox']:checked {_x000D_
    background: #abd;_x000D_
}

<input type="checkbox" />

If you don't want to use a separate JS library to create a custom control for that, you could use two confirm dialogs to do the checks:

if (confirm("Are you sure you want to quit?") ) {
    if (confirm("Save your work before leaving?") ) {
        // code here for save then leave (Yes)
    } else {
        //code here for no save but leave (No)
    }
} else {
    //code here for don't leave (Cancel)
}

A global variable would be best expressed in an external JavaScript file:

var system_status;

Make sure that this has not been used anywhere else. Then to access the variable on your page, just reference it as such. Say, for example, you wanted to fill in the results on a textbox,

document.getElementById("textbox1").value = system_status;

To ensure that the object exists, use the document ready feature of jQuery.

Example:

$(function() {
    $("#textbox1")[0].value = system_status;
});

It works for me:

OpenQA.Selenium.Interactions.Actions action 
    = new OpenQA.Selenium.Interactions.Actions(browser);
action.KeyDown(OpenQA.Selenium.Keys.Control)
    .SendKeys("a").KeyUp(OpenQA.Selenium.Keys.Control).Perform();

~ Tilde:

• ~ freezes major and minor numbers.
• It is used when you're ready to accept bug-fixes in your dependency, but don't want any potentially incompatible changes.
• The tilde matches the most recent minor version (the middle number).
• ~1.2.3 will match all 1.2.x versions, but it will miss 1.3.0.
• Tilde (~) gives you bug fix releases

^ Caret:

• ^ freezes the major number only.
• It is used when you're closely watching your dependencies and are ready to quickly change your code if minor release will be incompatible.
• It will update you to the most recent major version (the first number).
• ^1.2.3 will match any 1.x.x release including 1.3.0, but it will hold off on 2.0.0.
• Caret (^) gives you backwards-compatible new functionality as well.

why has no answer I've seen mentioned anything about the unwrap method? Or, even easier, the get_text method

http://www.crummy.com/software/BeautifulSoup/bs4/doc/#unwrap http://www.crummy.com/software/BeautifulSoup/bs4/doc/#get-text

To check if a Variant is Null, you need to do it like:

Isnull(myvar) = True

or

Not Isnull(myvar)

Another method is to use the CSSOM (CSS Object Model), via the style property on a DOM node.

var myElem = document.querySelector('.my-selector');
myElem.style.color = 'blue';

More details on CSSOM: https://developer.mozilla.org/en-US/docs/Web/API/HTMLElement.style

As mentioned by others, enabling unsafe-line for css is another method to solve this.

When you are using Lombok builder you will get the above error.

 @JsonDeserialize(builder = StationResponse.StationResponseBuilder.class)
 public class StationResponse{
   //define required properties 
 }

Sorry if I answer myself, but, at the finally, the solution of my problem was update Android Studio to the new version 0.8.14 by Canary Channel: http://tools.android.com/recent/

After the update, the problem is gone:

I leave this question here for those who have this problem in the future.

I think you want this syntax:

ALTER TABLE tb_TableName  
add constraint cnt_Record_Status Default '' for Record_Status

Based on some of your comments, I am going to guess that you might already have null values in your table which is causing the alter of the column to not null to fail. If that is the case, then you should run an UPDATE first. Your script will be:

update tb_TableName
set Record_Status  = ''
where Record_Status is null

ALTER TABLE tb_TableName
ALTER COLUMN Record_Status VARCHAR(20) NOT NULL

ALTER TABLE tb_TableName
ADD CONSTRAINT DEF_Name DEFAULT '' FOR Record_Status

See SQL Fiddle with demo

/**
 * Checks display and visibility of elements and it's parents
 * @param  DomElement  el
 * @param  boolean isDeep Watch parents? Default is true
 * @return {Boolean}
 *
 * @author Oleksandr Knyga <[email protected]>
 */
function isVisible(el, isDeep) {
    var elIsVisible = true;

    if("undefined" === typeof isDeep) {
        isDeep = true;
    }

    elIsVisible = elIsVisible && el.offsetWidth > 0 && el.offsetHeight > 0;

    if(isDeep && elIsVisible) {

        while('BODY' != el.tagName && elIsVisible) {
            elIsVisible = elIsVisible && 'hidden' != window.getComputedStyle(el).visibility;
            el = el.parentElement;
        }
    }

    return elIsVisible;
}

The following works for console applications;

1. Install the following NuGet packages (.csproj);

   <ItemGroup>
       <PackageReference Include="Microsoft.Extensions.Configuration" Version="2.2.0-preview2-35157" />
       <PackageReference Include="Microsoft.Extensions.Configuration.FileExtensions" Version="2.2.0-preview2-35157" />
       <PackageReference Include="Microsoft.Extensions.Configuration.Json" Version="2.2.0-preview2-35157" />
   </ItemGroup>
   

2. Create appsettings.json at root level. Right click on it and "Copy to Output Directory" as "Copy if newer".

3. Sample configuration file:

   {
     "AppConfig": {
       "FilePath": "C:\\temp\\logs\\output.txt"
     }
   }
   

4. Program.cs

   configurationSection.Key and configurationSection.Value will have config properties.

   static void Main(string[] args)
   {
       try
       {
   
           IConfigurationBuilder builder = new ConfigurationBuilder()
               .SetBasePath(Directory.GetCurrentDirectory())
               .AddJsonFile("appsettings.json", optional: true, reloadOnChange: true);
   
           IConfigurationRoot configuration = builder.Build();
           // configurationSection.Key => FilePath
           // configurationSection.Value => C:\\temp\\logs\\output.txt
           IConfigurationSection configurationSection = configuration.GetSection("AppConfig").GetSection("FilePath");
   
       }
       catch (Exception e)
       {
           Console.WriteLine(e);
       }
   }
   

Looks like older answers were fine for older Jackson versions, but since objectMapper has method setTimeZone(tz), setting time zone on a dateFormat is totally ignored.

How to properly setup timeZone to the ObjectMapper in Jackson version 2.11.0:

ObjectMapper objectMapper = new ObjectMapper();
objectMapper.setTimeZone(TimeZone.getTimeZone("Europe/Warsaw"));

Full example

  @Test
  void test() throws Exception {
    ObjectMapper objectMapper = new ObjectMapper();
    objectMapper.findAndRegisterModules();
    objectMapper.disable(SerializationFeature.WRITE_DATES_AS_TIMESTAMPS);
    JavaTimeModule module = new JavaTimeModule();
    objectMapper.registerModule(module);
    objectMapper.setTimeZone(TimeZone.getTimeZone("Europe/Warsaw"));

    ZonedDateTime now = ZonedDateTime.now();
    String converted = objectMapper.writeValueAsString(now);

    ZonedDateTime restored = objectMapper.readValue(converted, ZonedDateTime.class);
    System.out.println("serialized: " + now);
    System.out.println("converted: " + converted);
    System.out.println("restored: " + restored);

    Assertions.assertThat(now).isEqualTo(restored);
  }

Change the direction of UIButton image (RTL and LTR)

extension UIButton {
    func changeDirection(){
       isArabic ? (self.contentHorizontalAlignment = .right) : (self.contentHorizontalAlignment = .left)
        // left-right margin 
        self.imageEdgeInsets = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
        self.titleEdgeInsets = UIEdgeInsets(top: 0, left: 5, bottom: 0, right: 5)
    }
}

you can use "dynamicObject.PropertyName.Value" to get value of dynamic property directly.

Example :

d.property11.Value

Try the file command with -i option.

-i option Causes the file command to output mime type strings rather than the more traditional human readable ones. Thus it may say text/plain; charset=us-ascii rather than ASCII text.

Select cell B2 and click "Freeze Panes" this will freeze Row 1 and Column A.

For future reference, selecting Freeze Panes in Excel will freeze the rows above your selected cell and the columns to the left of your selected cell. For example, to freeze rows 1 and 2 and column A, you could select cell B3 and click Freeze Panes. You could also freeze columns A and B and row 1, by selecting cell C2 and clicking "Freeze Panes".

You can pass a format string to the ToString method, like so:

ToString("N4"); // 4 decimal points Number

If you want to see more modifiers, take a look at MSDN - Standard Numeric Format Strings

In Java, you cannot set a value in ArrayList by assigning to it, there's a set() method to call:

String a = words.get(0);
words.set(0, words.get(words.size() - 1));
words.set(words.size() - 1, a)

It is “old-fashioned” way to specify ranges of revisions you wish to merge. With 1.5+ you can use:

svn merge HEAD url/of/trunk path/to/branch/wc

According to Daniel Simmons:

Create a new ObjectContext instance in a Using statement for each service method so that it is disposed of before the method returns. This step is critical for scalability of your service. It makes sure that database connections are not kept open across service calls and that temporary state used by a particular operation is garbage collected when that operation is over. The Entity Framework automatically caches metadata and other information it needs in the app domain, and ADO.NET pools database connections, so re-creating the context each time is a quick operation.

This is from his comprehensive article here:

http://msdn.microsoft.com/en-us/magazine/ee335715.aspx

I believe this advice extends to HTTP requests, so would be valid for ASP.NET. A stateful, fat-client application such as a WPF application might be the only case for a "shared" context.

Accessing /data/app is possible without root permission; the permissions on that directory are rwxrwx--x. Execute permission on a directory means you can access it, however lack of read permission means you cannot obtain a listing of its contents -- so in order to access it you must know the name of the file that you will be accessing. Android's package manager will tell you the name of the stored apk for a given package.

To do this from the command line, use adb shell pm list packages to get the list of installed packages and find the desired package.

With the package name, we can get the actual file name and location of the APK using adb shell pm path your-package-name.

And knowing the full directory, we can finally pull the adb using adb pull full/directory/of/the.apk

Credit to @tarn for pointing out that under Lollipop, the apk path will be /data/app/your-package-name-1/base.apk

this answer helped me out a lot and pointed me in the right direction but what worked for me, and hopefully others, is:

menuApp.controller("dynamicMenuController", function($scope, $http) {
$scope.appetizers= [];
$http.get('config/menu.json').success(function(data) { 
    console.log("success!");
    $scope.appetizers = data.appetizers;
        console.log(data.appetizers);
    });    
});

If You are using Gunicorn and Nginx environment then the following code template works for you.

Using padding in the layout of Child View.

layout.xml

<?xml version="1.0" encoding="utf-8"?>
<TextView xmlns:android="http://schemas.android.com/apk/res/android"
          android:layout_width="wrap_content"
          android:layout_height="wrap_content"
          android:layout_margin="5dp"
          android:background="@drawable/backage_text"
          android:textColor="#999999"

used ast, example

In [15]: a = "[{'start_city': '1', 'end_city': 'aaa', 'number': 1},\
...:      {'start_city': '2', 'end_city': 'bbb', 'number': 1},\
...:      {'start_city': '3', 'end_city': 'ccc', 'number': 1}]"
In [16]: import ast
In [17]: ast.literal_eval(a)
Out[17]:
[{'end_city': 'aaa', 'number': 1, 'start_city': '1'},
 {'end_city': 'bbb', 'number': 1, 'start_city': '2'},
 {'end_city': 'ccc', 'number': 1, 'start_city': '3'}]

It might be possible that the file you are accessing has a swap copy (or swap version) already there in the same directory

Hence first see whether a hidden file exists or not.

For example, see for the following type of files

.system.conf.swp

By using the command

ls -a

And then, delete it using ...

rm .system.conf.swp

Usually, I recommend to start using super user privileges using ...

sudo su

You need the stat call, and the file name:

my $last_mod_time = (stat ($file))[9];

Perl also has a different version:

my $last_mod_time = -M $file;

but that value is relative to when the program started. This is useful for things like sorting, but you probably want the first version.

We are not getting the correct results because any javascript generated content needs to be rendered on the DOM. When we fetch an HTML page, we fetch the initial, unmodified by javascript, DOM.

Therefore we need to render the javascript content before we crawl the page.

As selenium is already mentioned many times in this thread (and how slow it gets sometimes was mentioned also), I will list two other possible solutions.

Solution 1: This is a very nice tutorial on how to use Scrapy to crawl javascript generated content and we are going to follow just that.

What we will need:

1. Docker installed in our machine. This is a plus over other solutions until this point, as it utilizes an OS-independent platform.

2. Install Splash following the instruction listed for our corresponding OS.
   Quoting from splash documentation:

   Splash is a javascript rendering service. It’s a lightweight web browser with an HTTP API, implemented in Python 3 using Twisted and QT5.

   Essentially we are going to use Splash to render Javascript generated content.

3. Run the splash server: sudo docker run -p 8050:8050 scrapinghub/splash.

4. Install the scrapy-splash plugin: pip install scrapy-splash

5. Assuming that we already have a Scrapy project created (if not, let's make one), we will follow the guide and update the settings.py:

   Then go to your scrapy project’s settings.py and set these middlewares:

   DOWNLOADER_MIDDLEWARES = {
         'scrapy_splash.SplashCookiesMiddleware': 723,
         'scrapy_splash.SplashMiddleware': 725,
         'scrapy.downloadermiddlewares.httpcompression.HttpCompressionMiddleware': 810,
   }
   

   The URL of the Splash server(if you’re using Win or OSX this should be the URL of the docker machine: How to get a Docker container's IP address from the host?):

   SPLASH_URL = 'http://localhost:8050'
   

   And finally you need to set these values too:

   DUPEFILTER_CLASS = 'scrapy_splash.SplashAwareDupeFilter'
   HTTPCACHE_STORAGE = 'scrapy_splash.SplashAwareFSCacheStorage'
   

6. Finally, we can use a SplashRequest:

   In a normal spider you have Request objects which you can use to open URLs. If the page you want to open contains JS generated data you have to use SplashRequest(or SplashFormRequest) to render the page. Here’s a simple example:

   class MySpider(scrapy.Spider):
       name = "jsscraper"
       start_urls = ["http://quotes.toscrape.com/js/"]
   
       def start_requests(self):
           for url in self.start_urls:
           yield SplashRequest(
               url=url, callback=self.parse, endpoint='render.html'
           )
   
       def parse(self, response):
           for q in response.css("div.quote"):
           quote = QuoteItem()
           quote["author"] = q.css(".author::text").extract_first()
           quote["quote"] = q.css(".text::text").extract_first()

   SplashRequest renders the URL as html and returns the response which you can use in the callback(parse) method.

Solution 2: Let's call this experimental at the moment (May 2018)...
This solution is for Python's version 3.6 only (at the moment).

Do you know the requests module (well who doesn't)?
Now it has a web crawling little sibling: requests-HTML:

This library intends to make parsing HTML (e.g. scraping the web) as simple and intuitive as possible.

1. Install requests-html: pipenv install requests-html

2. Make a request to the page's url:

   from requests_html import HTMLSession
   
   session = HTMLSession()
   r = session.get(a_page_url)
   

3. Render the response to get the Javascript generated bits:

   r.html.render()
   

Finally, the module seems to offer scraping capabilities.
Alternatively, we can try the well-documented way of using BeautifulSoup with the r.html object we just rendered.

If you add the android:theme="@style/Theme.AppCompat.Light" to <application> in AndroidManifest.xml file, problem is solving.

It is possible to upack without node installed using the following 7-Zip plugin:

Thanks @MayaPosch for mentioning that in this comment.

This happened to me with a page loaded in via an iframe. The iframe src page had a 404 script reference. Obviously I couldn't find the script reference in the parent page, so it took me a while to find the culprit.

public class CustomCollection : List<Object>
{
    public Object this[int index]
    {
        // ...
    }
}

My problem was to display the record even if no or only one phone number exists (full address book). Therefore I used a LEFT JOIN which takes all records from the left, even if no corresponding exists on the right. For me this works in Microsoft Access SQL (they require the parenthesis!)

SELECT t.PhoneNumber1, t.PhoneNumber2, t.PhoneNumber3
   t1.SomeOtherFieldForPhone1, t2.someOtherFieldForPhone2, t3.someOtherFieldForPhone3
FROM 
(
 (
  Table1 AS t LEFT JOIN Table2 AS t3 ON t.PhoneNumber3 = t3.PhoneNumber
 )
 LEFT JOIN Table2 AS t2 ON t.PhoneNumber2 = t2.PhoneNumber
)
LEFT JOIN Table2 AS t1 ON t.PhoneNumber1 = t1.PhoneNumber;

add this function in static class in project like utility class:

utility.cs content:

public static class Utility
{
    public static string GetBaseUrl()
    {
        var request = HttpContext.Current.Request;
        var urlHelper = new UrlHelper(request.RequestContext);
        var baseUrl = $"{request.Url.Scheme}://{request.Url.Authority}{urlHelper.Content("~")}";
        return baseUrl;
    }
}

use this code any where and enjoy it:

var baseUrl = Utility.GetBaseUrl();

To do the nil check and length simultaneously Swift 2.0 and iOS 9 onwards you could use

if(yourString?.characters.count > 0){}

This is how you can change hours without if statement:

hours = ((hours + 11) % 12 + 1);

(Alt + Shift + X) , then M to Run Maven Build. You will need to specify the Maven goals you want on Run -> Run Configurations

For detecting if the form is present, I'm using

if($('form[name="frmSave"]').length > 0) {
    //do something
}

You can use the following function to enqueue script or style from plugin.

function my_enqueued_assets() {
    wp_enqueue_script('my-js-file', plugin_dir_url(__FILE__) . '/js/script.js', '', time());
    wp_enqueue_style('my-css-file', plugin_dir_url(__FILE__) . '/css/style.css', '', time());
}
add_action('wp_enqueue_scripts', 'my_enqueued_assets');

You can pass you session variables from your php script to JQUERY using JSON such as

JS:

jQuery("#rowed2").jqGrid({
    url:'yourphp.php?q=3', 
    datatype: "json", 
    colNames:['Actions'], 
    colModel:[{
                name:'Actions',
                index:'Actions', 
                width:155,
                sortable:false
              }], 
    rowNum:30, 
    rowList:[50,100,150,200,300,400,500,600], 
    pager: '#prowed2', 
    sortname: 'id',
    height: 660,        
    viewrecords: true, 
    sortorder: 'desc',
    gridview:true,
    editurl: 'yourphp.php', 
    caption: 'Caption', 
    gridComplete: function() { 
        var ids = jQuery("#rowed2").jqGrid('getDataIDs'); 
        for (var i = 0; i < ids.length; i++) { 
            var cl = ids[i]; 
            be = "<input style='height:22px;width:50px;' `enter code here` type='button' value='Edit' onclick=\"jQuery('#rowed2').editRow('"+cl+"');\" />"; 
            se = "<input style='height:22px;width:50px;' type='button' value='Save' onclick=\"jQuery('#rowed2').saveRow('"+cl+"');\" />"; 
            ce = "<input style='height:22px;width:50px;' type='button' value='Cancel' onclick=\"jQuery('#rowed2').restoreRow('"+cl+"');\" />"; 
            jQuery("#rowed2").jqGrid('setRowData', ids[i], {Actions:be+se+ce}); 
        } 
    }
}); 

PHP

// start your session
session_start();

// get session from database or create you own
$session_username = $_SESSION['John'];
$session_email = $_SESSION['[email protected]'];

$response = new stdClass();
$response->session_username = $session_username;
$response->session_email = $session_email;

$i = 0;
while ($row = mysqli_fetch_array($result)) { 
    $response->rows[$i]['id'] = $row['ID']; 
    $response->rows[$i]['cell'] = array("", $row['rowvariable1'], $row['rowvariable2']); 
    $i++; 
} 

echo json_encode($response);
// this response (which contains your Session variables) is sent back to your JQUERY 

Observable: Different result for each Observer

One very very important difference. Since Observable is just a function, it does not have any state, so for every new Observer, it executes the observable create code again and again. This results in:

The code is run for each observer . If its a HTTP call, it gets called for each observer

This causes major bugs and inefficiencies

BehaviorSubject (or Subject ) stores observer details, runs the code only once and gives the result to all observers .

Ex:

JSBin: http://jsbin.com/qowulet/edit?js,console

// --- Observable ---_x000D_
let randomNumGenerator1 = Rx.Observable.create(observer => {_x000D_
   observer.next(Math.random());_x000D_
});_x000D_
_x000D_
let observer1 = randomNumGenerator1_x000D_
      .subscribe(num => console.log('observer 1: '+ num));_x000D_
_x000D_
let observer2 = randomNumGenerator1_x000D_
      .subscribe(num => console.log('observer 2: '+ num));_x000D_
_x000D_
_x000D_
// ------ BehaviorSubject/ Subject_x000D_
_x000D_
let randomNumGenerator2 = new Rx.BehaviorSubject(0);_x000D_
randomNumGenerator2.next(Math.random());_x000D_
_x000D_
let observer1Subject = randomNumGenerator2_x000D_
      .subscribe(num=> console.log('observer subject 1: '+ num));_x000D_
      _x000D_
let observer2Subject = randomNumGenerator2_x000D_
      .subscribe(num=> console.log('observer subject 2: '+ num));

<script src="https://cdnjs.cloudflare.com/ajax/libs/rxjs/5.5.3/Rx.min.js"></script>

Output :

"observer 1: 0.7184075243594013"
"observer 2: 0.41271850211336103"
"observer subject 1: 0.8034263165479893"
"observer subject 2: 0.8034263165479893"

Observe how using Observable.create created different output for each observer, but BehaviorSubject gave the same output for all observers. This is important.

Other differences summarized.

There's a node package for everything. It's cross-platform and easy to use.

$ npm install --global internal-ip-cli

$ internal-ip
fe80::1

$ internal-ip --ipv4
192.168.0.3

This is a controversial approach, but using npm for tooling is becoming more popular, like it or not.

Set environment variables and use headers to receive them:

You can create new environment variables with RewriteRule lines, as mentioned by OP:

RewriteRule ^(.*) - [E=TEST0:%{DOCUMENT_ROOT}/blog/html_cache/$1.html]

But if you can't get a server-side script to work, how can you then read this environment variable? One solution is to set a header:

Header set TEST_FOOBAR "%{REDIRECT_TEST0}e"

The value accepts format specifiers, including the %{NAME}e specifier for environment variables (don't forget the lowercase e). Sometimes, you'll need to add the REDIRECT_ prefix, but I haven't worked out when the prefix gets added and when it doesn't.

I think you declared the Equals method like this:

public override bool Equals(BOX obj)

Since the object.Equals method takes an object, there is no method to override with this signature. You have to override it like this:

public override bool Equals(object obj)

If you want type-safe Equals, you can implement IEquatable<BOX>.

You want to get the computed width. Try: .offsetWidth

(I.e: this.offsetWidth='50px' or var w=this.offsetWidth)

Place the image (cancel icon) with position absolute, adjust top and left properties and call method onclick event which clears the input field.

<div class="form-control">
    <input type="text" id="inputField" />
</div>
<span id="iconSpan"><img src="icon.png" onclick="clearInputField()"/></span>

In css position the span accordingly,

#iconSpan {
 position : absolute;
 top:1%;
 left :14%;
}

Here is how I author custom events:

var event = jQuery.Event('customEventName');
$(element).trigger(event);

Granted, you could simply do

$(element).trigger('eventname');

But the way I wrote allows you to detect whether the user has prevented default or not by doing

var prevented = event.isDefaultPrevented();

This allows you to listen to your end-user's request to stop processing a particular event, such as if you click a button element in a form but do not want to the form to post if there is an error.

I then usually listen to events like so

$(element).off('eventname.namespace').on('eventname.namespace', function () {
    ...
});

Once again, you could just do

$(element).on('eventname', function () {
    ...
});

But I've always found this somewhat unsafe, especially if you're working in a team.

There is nothing wrong with the following:

$(element).on('eventname', function () {});

However, assume that I need to unbind this event for whatever reason (imagine a disabled button). I would then have to do

$(element).off('eventname', function () {});

This will remove all eventname events from $(element). You cannot know whether someone in the future will also bind an event to that element, and you'd be inadvertently unbinding that event as well

The safe way to avoid this is to namespace your events by doing

$(element).on('eventname.namespace', function () {});

Lastly, you may have noticed that the first line was

$(element).off('eventname.namespace').on('eventname.namespace', ...)

I personally always unbind an event before binding it just to make sure that the same event handler never gets called multiple times (imagine this was the submit button on a payment form and the event had been bound 5 times)

attr_accessor is a Ruby method that makes a getter and a setter. attr_accessible is a Rails method that allows you to pass in values to a mass assignment: new(attrs) or update_attributes(attrs).

Here's a mass assignment:

Order.new({ :type => 'Corn', :quantity => 6 })

You can imagine that the order might also have a discount code, say :price_off. If you don't tag :price_off as attr_accessible you stop malicious code from being able to do like so:

Order.new({ :type => 'Corn', :quantity => 6, :price_off => 30 })

Even if your form doesn't have a field for :price_off, if it's in your model it's available by default. This means a crafted POST could still set it. Using attr_accessible white lists those things that can be mass assigned.

You can use IN operator as below

select * from dbo.books where isbn IN
(select isbn from dbo.lending where lended_date between @fdate and @tdate)

You can use the following code to get last cell.

UITableViewCell *cell = [tableView cellForRowAtIndexPath:lastIndexPath];

//MARK:- Add LeftBorder For View

(void)prefix_addLeftBorder:(UIView *) viewName
{
    CALayer *leftBorder = [CALayer layer];
    leftBorder.backgroundColor = [UIColor colorWithRed:221/255.0f green:221/255.0f blue:221/255.0f alpha:1.0f].CGColor;
    leftBorder.frame = CGRectMake(0,0,1.0,viewName.frame.size.height);
    [viewName.layer addSublayer:leftBorder];
}

//MARK:- Add RightBorder For View

(void)prefix_addRightBorder:(UIView *) viewName
{
    CALayer *rightBorder = [CALayer layer];
    rightBorder.backgroundColor = [UIColor colorWithRed:221/255.0f green:221/255.0f blue:221/255.0f alpha:1.0f].CGColor;
    rightBorder.frame = CGRectMake(viewName.frame.size.width - 1.0,0,1.0,viewName.frame.size.height);
    [viewName.layer addSublayer:rightBorder];
}

//MARK:- Add Bottom Border For View

(void)prefix_addbottomBorder:(UIView *) viewName
{
    CALayer *bottomBorder = [CALayer layer];
    bottomBorder.backgroundColor = [UIColor colorWithRed:221/255.0f green:221/255.0f blue:221/255.0f alpha:1.0f].CGColor;
    bottomBorder.frame = CGRectMake(0,viewName.frame.size.height - 1.0,viewName.frame.size.width,1.0);
    [viewName.layer addSublayer:bottomBorder];
}

I had the same issue too, the problem is exacerbated with the download link now only working for Visual Studio 2017, and installing the package from the download link did nothing for VS2015, although it took up 5gB of space.

I looked everywhere on how to do it with the Nu Get package manager and I couldn't find the solution.

It turns out it's even simpler than that, all you have to do is right-click the project or solution in the Solution Explorer from within Visual Studio, and click "Install Missing Components"

You don't need "string" in your call to wordLengthFunction().

int wordLength = wordLengthFunction(string word);

should be

int wordLength = wordLengthFunction(word);

What is the basic problem in your code?

Your code needs to be separated out in to interfaces(.h) and Implementations(.cpp).
The compiler needs to see the composition of a type when you write something like

ClassTwo obj;

This is because the compiler needs to reserve enough memory for object of type ClassTwo to do so it needs to see the definition of ClassTwo. The most common way to do this in C++ is to split your code in to header files and source files.
The class definitions go in the header file while the implementation of the class goes in to source files. This way one can easily include header files in to other source files which need to see the definition of class who's object they create.

Why can't I simply put all code in cpp files and include them in other files?

You cannot simple put all the code in source file and then include that source file in other files.C++ standard mandates that you can declare a entity as many times as you need but you can define it only once(One Definition Rule(ODR)). Including the source file would violate the ODR because a copy of the entity is created in every translation unit where the file is included.

How to solve this particular problem?

Your code should be organized as follows:

//File1.h

Define ClassOne 

//File2.h

#include <iostream>
#include <string>


class ClassTwo
{
private:
   string myType;
public:
   void setType(string);
   std::string getType();
}; 

//File1.cpp

#include"File1.h"

Implementation of ClassOne 

//File2.cpp

#include"File2.h"

void ClassTwo::setType(std::string sType)
{
    myType = sType;
}

void ClassTwo::getType(float fVal)
{
    return myType;
} 

//main.cpp

#include <iostream>
#include <string>
#include "file1.h"
#include "file2.h"
using namespace std;

int main()
{

    ClassOne cone;
    ClassTwo ctwo;

    //some codes
}

Is there any alternative means rather than including header files?

If your code only needs to create pointers and not actual objects you might as well use Forward Declarations but note that using forward declarations adds some restrictions on how that type can be used because compiler sees that type as an Incomplete type.

There is an easy way with Sharpeserializer (open source) :

http://www.sharpserializer.com/

It can directly serialize/de-serialize dictionary.

There is no need to mark your object with any attribute, nor do you have to give the object type in the Serialize method (See here ).

To install via nuget : Install-package sharpserializer

Then it is very simple :

Hello World (from the official website):

// create fake obj
var obj = createFakeObject();

// create instance of sharpSerializer
// with standard constructor it serializes to xml
var serializer = new SharpSerializer();

// serialize
serializer.Serialize(obj, "test.xml");

// deserialize
var obj2 = serializer.Deserialize("test.xml");

As far as I know you can use all mentioned technologies separately or together. It's up to you. I think you look at the problem from the wrong angle. Material Design is just the way particular elements of the page are designed, behave and put together. Material Design provides great UI/UX, but it relies on the graphic layout (HTML/CSS) rather than JS (events, interactions).

On the other hand, AngularJS and Bootstrap are front-end frameworks that can speed up your development by saving you from writing tons of code. For example, you can build web app utilizing AngularJS, but without Material Design. Or You can build simple HTML5 web page with Material Design without AngularJS or Bootstrap. Finally you can build web app that uses AngularJS with Bootstrap and with Material Design. This is the best scenario. All technologies support each other.

1. Bootstrap = responsive page
2. AngularJS = MVC
3. Material Design = great UI/UX

You can check awesome material design components for AngularJS:

I recently faced this problem. I tried all possible solutions but nothing worked. At the end I just quit the Xcode , removed the certificates in keychain and installed everything fresh and restarted mac. Fortunately it worked like charm :)

If you are using ASP.NET Core MVC project. This error message can be shown then you have the correct cshtml file in your Views folder but the action is missing in your controller.

Adding the missing action to the controller will fix it.

It was particular for me. I am sending a header named 'SESSIONHASH'. No problem for Chrome and Opera, but Firefox also wants this header in the list "Access-Control-Allow-Headers". Otherwise, Firefox will throw the CORS error.

It's working fine for me by the following way -

public async Task<object> TestMethod(TestModel model)
    {
        try
        {
            var apicallObject = new
            {
                Id= model.Id,
                name= model.Name
            };

            if (apicallObject != null)
            {
                var bodyContent = JsonConvert.SerializeObject(apicallObject);
                using (HttpClient client = new HttpClient())
                {
                    var content = new StringContent(bodyContent.ToString(), Encoding.UTF8, "application/json");
                    content.Headers.ContentType = new MediaTypeHeaderValue("application/json");
                    client.DefaultRequestHeaders.Add("access-token", _token); // _token = access token
                    var response = await client.PostAsync(_url, content); // _url =api endpoint url
                    if (response != null)
                    {
                        var jsonString = await response.Content.ReadAsStringAsync();

                        try
                        {
                            var result = JsonConvert.DeserializeObject<TestModel2>(jsonString); // TestModel2 = deserialize object
                        }
                        catch (Exception e){
                            //msg
                            throw e;
                        }
                    }
                }
            }
        }
        catch (Exception ex)
        {
            throw ex;
        }
        return null;
    }

I think (I'm not certain) that foreign key constraints won't do precisely what you want given your table design. Perhaps the best thing to do is to define a stored procedure that will delete a category the way you want, and then call that procedure whenever you want to delete a category.

CREATE PROCEDURE `DeleteCategory` (IN category_ID INT)
LANGUAGE SQL
NOT DETERMINISTIC
MODIFIES SQL DATA
SQL SECURITY DEFINER
BEGIN

DELETE FROM
    `products`
WHERE
    `id` IN (
        SELECT `products_id`
        FROM `categories_products`
        WHERE `categories_id` = category_ID
    )
;

DELETE FROM `categories`
WHERE `id` = category_ID;

END

You also need to add the following foreign key constraints to the linking table:

ALTER TABLE `categories_products` ADD
    CONSTRAINT `Constr_categoriesproducts_categories_fk`
    FOREIGN KEY `categories_fk` (`categories_id`) REFERENCES `categories` (`id`)
    ON DELETE CASCADE ON UPDATE CASCADE,
    CONSTRAINT `Constr_categoriesproducts_products_fk`
    FOREIGN KEY `products_fk` (`products_id`) REFERENCES `products` (`id`)
    ON DELETE CASCADE ON UPDATE CASCADE

The CONSTRAINT clause can, of course, also appear in the CREATE TABLE statement.

Having created these schema objects, you can delete a category and get the behaviour you want by issuing CALL DeleteCategory(category_ID) (where category_ID is the category to be deleted), and it will behave how you want. But don't issue a normal DELETE FROM query, unless you want more standard behaviour (i.e. delete from the linking table only, and leave the products table alone).

Simply put a file named favicon.ico in the webroot.

function alphaOnly(event) {
  var key = event.keyCode;
  return ((key >= 65 && key <= 90) || key == 8);
};

or

function lettersOnly(evt) {
       evt = (evt) ? evt : event;
       var charCode = (evt.charCode) ? evt.charCode : ((evt.keyCode) ? evt.keyCode :
          ((evt.which) ? evt.which : 0));
       if (charCode > 31 && (charCode < 65 || charCode > 90) &&
          (charCode < 97 || charCode > 122)) {
          alert("Enter letters only.");
          return false;
       }
       return true;
     }

Necromancing.

In order to not depend on the user-agent string, just check for a few properties:

if (document.documentMode) 
{
    console.log('Hello Microsoft IE User!');
}

if (!document.documentMode && window.msWriteProfilerMark) {
    console.log('Hello Microsoft Edge User!');
}

if (document.documentMode || window.msWriteProfilerMark) 
{
    console.log('Hello Microsoft User!');
}

if (window.msWriteProfilerMark) 
{
    console.log('Hello Microsoft User in fewer characters!');
}

Also, this detects the new Chredge/Edgium (Anaheim):

function isEdg()
{ 

    for (var i = 0, u="Microsoft", l =u.length; i < navigator.plugins.length; i++)
    {
        if (navigator.plugins[i].name != null && navigator.plugins[i].name.substr(0, l) === u)
            return true;
    }

    return false;
}

And this detects chromium:

function isChromium()
{ 

    for (var i = 0, u="Chromium", l =u.length; i < navigator.plugins.length; i++)
    {
        if (navigator.plugins[i].name != null && navigator.plugins[i].name.substr(0, l) === u)
            return true;
    }

    return false;
}

And this Safari:

if(window.safari)
{
    console.log("Safari, yeah!");
}

You need to extract the number from the string, and pass it into the Date constructor:

var x = [{
    "id": 1,
    "start": "\/Date(1238540400000)\/"
}, {
    "id": 2,
    "start": "\/Date(1238626800000)\/"
}];

var myDate = new Date(x[0].start.match(/\d+/)[0] * 1);

The parts are:

x[0].start                                - get the string from the JSON
x[0].start.match(/\d+/)[0]                - extract the numeric part
x[0].start.match(/\d+/)[0] * 1            - convert it to a numeric type
new Date(x[0].start.match(/\d+/)[0] * 1)) - Create a date object

Using Float.parseFloat()?

class Test {
    public static void main(String[] args) {
        String s = "3.14";
        float f = Float.parseFloat(s);
        System.out.println(f);
    }
}

FYI to anyone who runs into problems, there is a bug in CSV timestamp export that I just spent a few hours working around. Some fields I needed to export were of type timestamp. It appears the CSV export option even in the current version (3.0.04 as of this posting) fails to put the grouping symbols around timestamps. Very frustrating since spaces in the timestamps broke my import. The best workaround I found was to write my query with a TO_CHAR() on all my timestamps, which yields the correct output, albeit with a little more work. I hope this saves someone some time or gets Oracle on the ball with their next release.

int a = 1;
char * c = (char*)(&a); //In C++ should be intermediate cst to void*

I strongly recommend taking a look at Vuex, it is made for globally accessible data in Vue.

If you only need a few base variables that will never be modified, I would use ES6 imports:

// config.js
export default {
   hostname: 'myhostname'
}

// .vue file
import config from 'config.js'

console.log(config.hostname)

You could also import a json file in the same way, which can be edited by people without code knowledge or imported into SASS.

Ranking by stars or forks is not working. Each promoted or created by a famous company repository is popular at the beginning. Also it is possible to have a number of them which are in trend right now (publications, marketing, events). It doesn't mean that those repositories are useful/popular.

The gitmostwanted.com project (repo at github) analyses GH Archive data in order to highlight the most interesting repositories and exclude others. Just compare the results with mentioned resources.

Many ways this can be achieved.

Simple approach should be taking Substring of an input string.

var result = input.Substring(input.Length - 3);

Another approach using Regular Expression to extract last 3 characters.

var result = Regex.Match(input,@"(.{3})\s*$");

Working Demo

When using a <select> tag that shows all options, here's a work around using <div> instead:

HTML

<div id='sectionOptionsSelect' size='5' class='block1'
        style='visibility: hidden; border: 1px solid gray; padding: 5px; '>
    <span class='addPageBreakAbove'>Add Page Break Above</span>
    <span class='addPageBreakBelow'>Add Page Break Below</span>
    <span class='removeSection'>
        <label class='fa fa-window-close'
               style='font-size: 25px; color: red; background: white; '></label>
        Remove Section</span>
</div>

Supporting JS

$('#sectionOptionsSelect span').hover(function () {

    $(this).css('background', '#c0ec67');

}, function () {

    $(this).css('background', 'transparent');
});

$('.removeSection').click(function () {

    alert('removeSection');
});

CSS

#sectionOptionsSelect span {
    display: block;
}

Javascript has a function just for that: Array.prototype.find. As example

function isBigEnough(element) {
  return element >= 15;
}

[12, 5, 8, 130, 44].find(isBigEnough); // 130

It not difficult to extends the callback to a function. However this is not compatible with IE (and partially with Edge). For a full list look at the Browser Compatibility

Create a class and give it an __init__ method:

class Student:
    def __init__(self, name, age, major):
        self.name = name
        self.age = age
        self.major = major

    def is_old(self):
        return self.age > 100

Now, you can initialize an instance of the Student class:

>>> s = Student('John', 88, None)
>>> s.name
    'John'
>>> s.age
    88

Although I'm not sure why you need a make_student student function if it does the same thing as Student.__init__.

You Also wanna put some text (placeholder) in the empty input box for the

.myClass {_x000D_
   ::-webkit-input-placeholder {_x000D_
    color: #f00;_x000D_
  }_x000D_
   ::-moz-placeholder {_x000D_
    color: #f00;_x000D_
  }_x000D_
  /* firefox 19+ */_x000D_
   :-ms-input-placeholder {_x000D_
    color: #f00;_x000D_
  }_x000D_
  /* ie */_x000D_
  input:-moz-placeholder {_x000D_
    color: #f00;_x000D_
  }_x000D_
}

<input type="text" class="myClass" id="fname" placeholder="Enter First Name Here!">

user to understand what to type.

EDIT

Starting with Android Studio 3.1, you should go to:

File -> Sync Project with Gradle Files

OLD

Clicking the button 'Sync Project With Gradle Files' should do the trick:

Tools -> Android -> Sync Project with Gradle Files

If that fails, try running 'Rebuild project':

Build -> Rebuild Project

I had this issue but I was able to resolve this by right clicking and using Run as Administrator. This boots up the program just fine.

Another approach which allows you to specify how many numbers you want with size and the min and max values of the returned numbers

public static int getRandomInt(int min, int max) {
    Random random = new Random();

    return random.nextInt((max - min) + 1) + min;
}

public static ArrayList<Integer> getRandomNonRepeatingIntegers(int size, int min,
        int max) {
    ArrayList<Integer> numbers = new ArrayList<Integer>();

    while (numbers.size() < size) {
        int random = getRandomInt(min, max);

        if (!numbers.contains(random)) {
            numbers.add(random);
        }
    }

    return numbers;
}

To use it returning 7 numbers between 0 and 25.

    ArrayList<Integer> list = getRandomNonRepeatingIntegers(7, 0, 25);
    for (int i = 0; i < list.size(); i++) {
        System.out.println("" + list.get(i));
    }

Yet another node based simple command line server

https://github.com/greggman/servez-cli

Written partly in response to http-server having issues, particularly on windows.

installation

Install node.js then

npm install -g servez

usage

servez [options] [path]

With no path it serves the current folder.

By default it serves index.html for folder paths if it exists. It serves a directory listing for folders otherwise. It also serves CORS headers. You can optionally turn on basic authentication with --username=somename --password=somepass and you can serve https.

var str = "0000000...0000";
var arr = str.split("");

usage in expressions: arr[i]*1;

EDIT: if arr supposed to be used in integer expressions, then please don't mind the char value of '0'. You just use it as follows: a = a * arr[i] (assuming a has integer value).

This one worked for me (in 2021):

tar -xf test.zip

This will unzip the test in the current directory.

    //load css first, then print <link> to header, and execute callback
    //just set var href above this..
    $.ajax({
          url: href,
          dataType: 'css',
          success: function(){                  
                $('<link rel="stylesheet" type="text/css" href="'+href+'" />').appendTo("head");
                //your callback
            }
    });

For Jquery 1.2.6 and above ( omitting the fancy attributes functions above ).

I am doing it this way because I think that this will ensure that your requested stylesheet is loaded by ajax before you try to stick it into the head. Therefore, the callback is executed after the stylesheet is ready.

It is all but satisfying, isn't it? The easiest way I have found to specify when setting the context, e.g.:

sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})   

This should take care of 90% of standard plotting usage. If you want ticklabels smaller than axes labels, set the 'axes.labelsize' to the smaller (ticklabel) value and specify axis labels (or other custom elements) manually, e.g.:

axs.set_ylabel('mylabel',size=6)

you could define it as a function and load it in your scripts so you don't have to remember your standard numbers, or call it every time.

def set_pubfig:
    sns.set_context("paper", rc={"font.size":8,"axes.titlesize":8,"axes.labelsize":5})   

Of course you can use configuration files, but I guess the whole idea is to have a simple, straightforward method, which is why the above works well.

Note: If you specify these numbers, specifying font_scale in sns.set_context is ignored for all specified font elements, even if you set it.

The return statements should place in one line. Or the other option is to remove the curly brackets that bound the HTML statement.

example:

return posts.map((post, index) =>
    <div key={index}>
      <h3>{post.title}</h3>
      <p>{post.body}</p>
    </div>
);

You need to configure the war plugin:

<project>
  ...
  <build>
    <plugins>
      <plugin>
        <groupId>org.apache.maven.plugins</groupId>
        <artifactId>maven-war-plugin</artifactId>
        <version>2.3</version>
        <configuration>
          <warName>bird.war</warName>
        </configuration>
      </plugin>
    </plugins>
  </build>
  ...
</project>

I had all my settings covered in the accepted answer. The problem I had was that I was trying to update the Entity Framework entity type "Task" like:

public IHttpActionResult Post(Task task)

What worked for me was to create my own entity "DTOTask" like:

public IHttpActionResult Post(DTOTask task)

I have a simple approach.

Step 1: Mount /var/run/docker.sock:/var/run/docker.sock (So you will be able to execute docker commands inside your container)

Step 2: Execute this below inside your container. The key part here is (--network host as this will execute from host context)

docker run -i --rm --network host -v /opt/test.sh:/test.sh alpine:3.7 sh /test.sh

test.sh should contain the some commands (ifconfig, netstat etc...) whatever you need. Now you will be able to get host context output.

You can't do something like that: (int(sumall[0])+int(sumall[1]))

That's because sumall is an int and not a list or dict.

So, summ + sumd will be you're lucky number

Everything is mirrored on omapzoom.org. Some of the code is also mirrored on github.

Contacts is here for example.

Since December 2019, you can use the new official public code search tool for AOSP: cs.android.com. There's also the Android official source browser (based on Gitiles) has a web view of many of the different parts that make up android. Some of the projects (such as Kernel) have been removed and it now only points you to clonable git repositories.

To get all the code locally, you can use the repo helper program, or you can just clone individual repositories.

And others:

• Downloading the Source Tree

This is how did it works like a charm.

CSS

#loader {
position:fixed;
left:1px;
top:1px;
width: 100%;
height: 100%;
z-index: 9999;

background: url('../images/ajax-loader100X100.gif') 50% 50% no-repeat rgb(249,249,249);
}  

in _layout file inside body tag but outside the container div. Every time page loads it shows loading. Once page is loaded JS fadeout(second)

<div id="loader">
</div>

JS at the bottom of _layout file

<script type="text/javascript">
// With the element initially shown, we can hide it slowly:
 $("#loader").fadeOut(1000);
</script>  

C++03 (Source: Iterator Invalidation Rules (C++03))

Insertion

Sequence containers

• vector: all iterators and references before the point of insertion are unaffected, unless the new container size is greater than the previous capacity (in which case all iterators and references are invalidated) [23.2.4.3/1]
• deque: all iterators and references are invalidated, unless the inserted member is at an end (front or back) of the deque (in which case all iterators are invalidated, but references to elements are unaffected) [23.2.1.3/1]
• list: all iterators and references unaffected [23.2.2.3/1]

Associative containers

• [multi]{set,map}: all iterators and references unaffected [23.1.2/8]

Container adaptors

• stack: inherited from underlying container
• queue: inherited from underlying container
• priority_queue: inherited from underlying container

Erasure

Sequence containers

• vector: every iterator and reference after the point of erase is invalidated [23.2.4.3/3]
• deque: all iterators and references are invalidated, unless the erased members are at an end (front or back) of the deque (in which case only iterators and references to the erased members are invalidated) [23.2.1.3/4]
• list: only the iterators and references to the erased element is invalidated [23.2.2.3/3]

Associative containers

• [multi]{set,map}: only iterators and references to the erased elements are invalidated [23.1.2/8]

Container adaptors

• stack: inherited from underlying container
• queue: inherited from underlying container
• priority_queue: inherited from underlying container

Resizing

• vector: as per insert/erase [23.2.4.2/6]
• deque: as per insert/erase [23.2.1.2/1]
• list: as per insert/erase [23.2.2.2/1]

Note 1

Unless otherwise specified (either explicitly or by defining a function in terms of other functions), invoking a container member function or passing a container as an argument to a library function shall not invalidate iterators to, or change the values of, objects within that container. [23.1/11]

Note 2

It's not clear in C++2003 whether "end" iterators are subject to the above rules; you should assume, anyway, that they are (as this is the case in practice).

Note 3

The rules for invalidation of pointers are the sames as the rules for invalidation of references.

All links to the Azure Active Directory Connection page now seem to be invalid.

I had an older version of Azure AD installed too, this is what worked for me. Install this.

Run these in an elevated PS session:

uninstall-module AzureAD  # this may or may not be needed
install-module AzureAD
install-module AzureADPreview
install-module MSOnline

I was then able to log in and run what I needed.

I am using Spring 3.2.4 and Jackson FasterXML 2.1.1.

I have created a custom JacksonObjectMapper that works with explicit annotations for each attribute of the Objects mapped:

package com.test;
import com.fasterxml.jackson.annotation.JsonAutoDetect;
import com.fasterxml.jackson.annotation.PropertyAccessor;
import com.fasterxml.jackson.databind.ObjectMapper;
import com.fasterxml.jackson.databind.SerializationFeature;

public class MyJaxbJacksonObjectMapper extends ObjectMapper {

public MyJaxbJacksonObjectMapper() {

    this.setVisibility(PropertyAccessor.FIELD, JsonAutoDetect.Visibility.ANY)
            .setVisibility(PropertyAccessor.CREATOR, JsonAutoDetect.Visibility.ANY)
            .setVisibility(PropertyAccessor.SETTER, JsonAutoDetect.Visibility.NONE)
            .setVisibility(PropertyAccessor.GETTER, JsonAutoDetect.Visibility.NONE)
            .setVisibility(PropertyAccessor.IS_GETTER, JsonAutoDetect.Visibility.NONE);

    this.configure(SerializationFeature.FAIL_ON_EMPTY_BEANS, false);
    }
}

Then this is instantiated in the context-configuration (servlet-context.xml):

<mvc:annotation-driven>
    <mvc:message-converters>

        <beans:bean class="org.springframework.http.converter.json.MappingJackson2HttpMessageConverter">
            <beans:property name="objectMapper">
                <beans:bean class="com.test.MyJaxbJacksonObjectMapper" />
            </beans:property>
        </beans:bean>

    </mvc:message-converters>
</mvc:annotation-driven>

This works fine!

EDIT:

Ok i was previously not aware that AngularJS usually refers to Angular v1 version and only Angular to Angular v2+

This answer only applies for Angular

Leaving this here for future reference..

Not sure how it works for you guys but on Angular 9 i have to wrap ngStyle in brackets like this:

[ng-style]="{ 'width' : (myObject.value == 'ok') ? '100%' : '0%' }"

Otherwise it doesn't work

If for some reason you don't want to define a Person class and use List<Person> as advised, you can use a tuple, such as (C# 7):

var people = new List<(string Name, string Email)>
{
  ("Joe Bloggs", "[email protected]"),
  ("George Forman", "[email protected]"),
  ("Peter Pan", "[email protected]")
};

var georgeEmail = people[1].Email;

The Name and Email member names are optional, you can omit them and access them using Item1 and Item2 respectively.

There are defined tuples for up to 8 members.

For earlier versions of C#, you can still use a List<Tuple<string, string>> (or preferably ValueTuple using this NuGet package), but you won't benefit from customized member names.

With ASP.NET 5 there is no Request variable available anymore. You can access it now with Context.Request

Also there is no IsAjaxRequest() Method anymore, you have to write it by yourself, for example in Extensions\HttpRequestExtensions.cs

using System;
using Microsoft.AspNetCore.Http;

namespace Microsoft.AspNetCore.Mvc
{
    public static class HttpRequestExtensions
    {
        public static bool IsAjaxRequest(this HttpRequest request)
        {
            if (request == null)
            {
                throw new ArgumentNullException(nameof(request));
            }

            return (request.Headers != null) && (request.Headers["X-Requested-With"] == "XMLHttpRequest");
        }
    }
}

I searched for a while now on this and hope that will help some others too ;)

Consider changing your markup to this:

<span id="someId">onlineff</span>

Then you can use this script:

var x = document.getElementById('someId');
x.style.color = '#00FF00';

see it here: http://jsfiddle.net/2ANmM/

You use the Python 2 docs but write your program in Python 3.

butangDonload.php

$file = "Bang.png"; //Let say If I put the file name Bang.png
$_SESSION['name']=$file;    

Try this,

<?php

$name=$_SESSION['name'];
download($name);

function download($name){
$file = $nama_fail;
?>

The "new" way of doing this since jQuery 1.5 (Jan 2011) is to use deferred objects instead of passing a success callback. You should return the result of $.ajax and then use the .done, .fail etc methods to add the callbacks outside of the $.ajax call.

function getData() {
    return $.ajax({
        url : 'example.com',
        type: 'GET'
    });
}

function handleData(data /* , textStatus, jqXHR */ ) {
    alert(data);
    //do some stuff
}

getData().done(handleData);

This decouples the callback handling from the AJAX handling, allows you to add multiple callbacks, failure callbacks, etc, all without ever needing to modify the original getData() function. Separating the AJAX functionality from the set of actions to be completed afterwards is a good thing!.

Deferreds also allow for much easier synchronisation of multiple asynchronous events, which you can't easily do just with success:

For example, I could add multiple callbacks, an error handler, and wait for a timer to elapse before continuing:

// a trivial timer, just for demo purposes -
// it resolves itself after 5 seconds
var timer = $.Deferred();
setTimeout(timer.resolve, 5000);

// add a done handler _and_ an `error:` handler, even though `getData`
// didn't directly expose that functionality
var ajax = getData().done(handleData).fail(error);

$.when(timer, ajax).done(function() {
    // this won't be called until *both* the AJAX and the 5s timer have finished
});

ajax.done(function(data) {
    // you can add additional callbacks too, even if the AJAX call
    // already finished
});

Other parts of jQuery use deferred objects too - you can synchronise jQuery animations with other async operations very easily with them.

In the second image it looks like you want the image to fill the box, but the example you created DOES keep the aspect ratio (the pets look normal, not slim or fat).

I have no clue if you photoshopped those images as example or the second one is "how it should be" as well (you said IS, while the first example you said "should")

Anyway, I have to assume:

If "the images are not resized keeping the aspect ration" and you show me an image which DOES keep the aspect ratio of the pixels, I have to assume you are trying to accomplish the aspect ratio of the "cropping" area (the inner of the green) WILE keeping the aspect ratio of the pixels. I.e. you want to fill the cell with the image, by enlarging and cropping the image.

If that's your problem, the code you provided does NOT reflect "your problem", but your starting example.

Given the previous two assumptions, what you need can't be accomplished with actual images if the height of the box is dynamic, but with background images. Either by using "background-size: contain" or these techniques (smart paddings in percents that limit the cropping or max sizes anywhere you want): http://fofwebdesign.co.uk/template/_testing/scale-img/scale-img.htm

The only way this is possible with images is if we FORGET about your second iimage, and the cells have a fixed height, and FORTUNATELY, judging by your sample images, the height stays the same!

So if your container's height doesn't change, and you want to keep your images square, you just have to set the max-height of the images to that known value (minus paddings or borders, depending on the box-sizing property of the cells)

Like this:

<div class="content">
  <div class="row">    
      <div class="cell">    
          <img src="http://lorempixel.com/output/people-q-c-320-320-2.jpg"/>
      </div>
      <div class="cell">    
          <img src="http://lorempixel.com/output/people-q-c-320-320-7.jpg"/>
      </div>
    </div>
</div>

And the CSS:

.content {
    background-color: green;
}

.row {
    display: -webkit-box;
    display: -moz-box;
    display: -ms-flexbox;
    display: -webkit-flex;

Your code is invalid (opening tags are instead of closing ones, so they output NESTED cells, not siblings, he used a SCREENSHOT of your images inside the faulty code, and the flex box is not holding the cells but both examples in a column (you setup "row" but the corrupt code nesting one cell inside the other resulted in a flex inside a flex, finally working as COLUMNS. I have no idea what you wanted to accomplish, and how you came up with that code, but I'm guessing what you want is this.

I added display: flex to the cells too, so the image gets centered (I think display: table could have been used here as well with all this markup)

Please find below example to load image using JavaFX.

    import javafx.application.Application;
    import javafx.scene.Scene;
    import javafx.scene.image.Image;
    import javafx.scene.image.ImageView;
    import javafx.scene.layout.StackPane;
    import javafx.stage.Stage;

    public class LoadImage extends Application {

    public static void main(String[] args) {
    Application.launch(args);
    }
    @Override
    public void start(Stage primaryStage) {
    primaryStage.setTitle("Load Image");

    StackPane sp = new StackPane();
    Image img = new Image("javafx.jpg");
    ImageView imgView = new ImageView(img);
    sp.getChildren().add(imgView);

    //Adding HBox to the scene
    Scene scene = new Scene(sp);
    primaryStage.setScene(scene);
    primaryStage.show();
    }

  }

Create one source folder with name Image in your project and add your image to that folder otherwise you can directly load image from external URL like following.

Image img = new Image("http://mikecann.co.uk/wp-content/uploads/2009/12/javafx_logo_color_1.jpg");

The error is due the fact that you are passing a wrong to strcat(). Look at strcat()'s prototype:

   char *strcat(char *dest, const char *src);

But you pass char as the second argument, which is obviously wrong.

Use snprintf() instead.

char str[1024] = "Hello World";
char tmp = '.';
size_t len = strlen(str);

snprintf(str + len, sizeof str - len, "%c", tmp);

As commented by OP:

That was just a example with Hello World to describe the Problem. It must be empty as first in my real program. Program will fill it later. The problem just contains to add a char/int to an char Array

In that case, snprintf() can handle it easily to "append" integer types to a char buffer too. The advantage of snprintf() is that it's more flexible to concatenate various types of data into a char buffer.

For example to concatenate a string, char and an int:

char str[1024];
ch tmp = '.';
int i = 5;

// Fill str here

snprintf(str + len, sizeof str - len, "%c%d", str, tmp, i);

if you want to do very quick plots with secondary Y-Axis then there is much easier way using Pandas wrapper function and just 2 lines of code. Just plot your first column then plot the second but with parameter secondary_y=True, like this:

df.A.plot(label="Points", legend=True)
df.B.plot(secondary_y=True, label="Comments", legend=True)

This would look something like below:

You can do few more things as well. Take a look at Pandas plotting doc.

And if you are already using ES6/ES2015 then you can also use an arrow function. It is basically the same as using a normal anonymous function but shorter.

expect(() => model.get('z')).to.throw('Property does not exist in model schema.');

Very close to what you posted, actually.

To get the assigned value, or default if it's missing:

FOO="${VARIABLE:-default}"  # If variable not set or null, use default.

Or to assign default to VARIABLE at the same time:

FOO="${VARIABLE:=default}"  # If variable not set or null, set it to default.

You're probably better off comparing the fields individually, rather than concatenating the strings.

SELECT t1.*
    FROM Table1 t1

I made a reactive version that accepts callbacks for stdOut and StdErr.
onStdOut and onStdErr are called asynchronously,
as soon as data arrives (before the process exits).

public static Int32 RunProcess(String path,
                               String args,
                       Action<String> onStdOut = null,
                       Action<String> onStdErr = null)
    {
        var readStdOut = onStdOut != null;
        var readStdErr = onStdErr != null;

        var process = new Process
        {
            StartInfo =
            {
                FileName = path,
                Arguments = args,
                CreateNoWindow = true,
                UseShellExecute = false,
                RedirectStandardOutput = readStdOut,
                RedirectStandardError = readStdErr,
            }
        };

        process.Start();

        if (readStdOut) Task.Run(() => ReadStream(process.StandardOutput, onStdOut));
        if (readStdErr) Task.Run(() => ReadStream(process.StandardError, onStdErr));

        process.WaitForExit();

        return process.ExitCode;
    }

    private static void ReadStream(TextReader textReader, Action<String> callback)
    {
        while (true)
        {
            var line = textReader.ReadLine();
            if (line == null)
                break;

            callback(line);
        }
    }

Example usage

The following will run executable with args and print

• stdOut in white
• stdErr in red

to the console.

RunProcess(
    executable,
    args,
    s => { Console.ForegroundColor = ConsoleColor.White; Console.WriteLine(s); },
    s => { Console.ForegroundColor = ConsoleColor.Red;   Console.WriteLine(s); } 
);

In my case, the file ~/.curlrc had a wrong proxy configured.

Use a line algorithm to connect point A with point C, and in an outer loop, let point A wander towards point B with the same line algorithm and with the wandering coordinates, repeat drawing that line. You can probably also include a z delta with which is also incremented iteratively. For the line algorithm, just calculate two or three slopes for the delta change of each coordinate and set one slope to 1 after changing the two others proportionally so they are below 1. This is very important for drawing closed geometrical areas between connected mesh particles. Take a look at the Qt Elastic Nodes example and now imagine drawing triangles between the nodes after stretching this over a skeleton. As long as it will remain online

Yes you can use CASE

UPDATE table 
SET columnB = CASE fieldA 
        WHEN columnA=1 THEN 'x' 
        WHEN columnA=2 THEN 'y' 
        ELSE 'z' 
      END 
WHERE columnC = 1

no need to require the ckeditor.php, because CKEditor will not processed by PHP...

you need just following the _samples directory and see what they do.

just need to include ckeditor.js by html tag, and do some configuration in javascript.

If you want logical calendar days, use DAYS.between() method from java.time.temporal.ChronoUnit:

LocalDate dateBefore;
LocalDate dateAfter;
long daysBetween = DAYS.between(dateBefore, dateAfter);

If you want literal 24 hour days, (a duration), you can use the Duration class instead:

LocalDate today = LocalDate.now()
LocalDate yesterday = today.minusDays(1);
// Duration oneDay = Duration.between(today, yesterday); // throws an exception
Duration.between(today.atStartOfDay(), yesterday.atStartOfDay()).toDays() // another option

Were you expecting player to be a dict rather than a list?

>>> player=[1,2,3]
>>> player["score"]
Traceback (most recent call last):

TypeError: list indices must be integers, not str
>>> player={'score':1, 'age': 2, "foo":3}
>>> player['score']

This is possible with window.localStorage or window.sessionStorage. The difference is that sessionStorage lasts for as long as the browser stays open, localStorage survives past browser restarts. The persistence applies to the entire web site not just a single page of it.

When you need to set a variable that should be reflected in the next page(s), use:

var someVarName = "value";
localStorage.setItem("someVarKey", someVarName);

And in any page (like when the page has loaded), get it like:

var someVarName = localStorage.getItem("someVarKey");

.getItem() will return null if no value stored, or the value stored.

Note that only string values can be stored in this storage, but this can be overcome by using JSON.stringify and JSON.parse. Technically, whenever you call .setItem(), it will call .toString() on the value and store that.

MDN's DOM storage guide (linked below), has workarounds/polyfills, that end up falling back to stuff like cookies, if localStorage isn't available.

It wouldn't be a bad idea to use an existing, or create your own mini library, that abstracts the ability to save any data type (like object literals, arrays, etc.).

I think the xpath query you want goes something like this:

/xml/box[@stepId="$stepId"]/components/component[@id="$componentId"]/variables/variable[@nom="Enabled" and @valeur="Yes"]

This should get you the variables that are named "Enabled" with a value of "Yes" for the specified $stepId and $componentId. This is assuming that your xml starts with an tag like you show, and not

If the SQL Server 2005 XPath stuff is pretty straightforward (I've never used it), then the above query should work. Otherwise, someone else may have to help you with that.

Interpolate:

body
    height: calc(100% - #{$body_padding})

For this case, border-box would also suffice:

body
    box-sizing: border-box
    height: 100%
    padding-top: $body_padding

Just pass it as normal parameters and access it in PHP using the $argv array.

php myfile.php daily

and in myfile.php

$type = $argv[1];

Or in pure WPF use PointToScreen.

Sample helper method:

// Gets the absolute mouse position, relative to screen
Point GetMousePos() => _window.PointToScreen(Mouse.GetPosition(_window));

Maven lets you specify either goals or lifecycle phases on the command line (or both).

clean and install are two different phases of two different lifecycles, to which different plugin goals are bound (either per default or explicitly in your pom.xml)

The clean phase, per convention, is meant to make a build reproducible, i.e. it cleans up anything that was created by previous builds. In most cases it does that by calling clean:clean, which deletes the directory bound to ${project.build.directory} (usually called "target")

I find it useful to have a class, derived from threading.Thread, to encapsulate my thread functionality. You simply provide your own main loop in an overridden version of run() in this class. Calling start() arranges for the object’s run() method to be invoked in a separate thread.

Inside the main loop, periodically check whether a threading.Event has been set. Such an event is thread-safe.

Inside this class, you have your own join() method that sets the stop event object before calling the join() method of the base class. It can optionally take a time value to pass to the base class's join() method to ensure your thread is terminated in a short amount of time.

import threading
import time

class MyThread(threading.Thread):
    def __init__(self, sleep_time=0.1):
        self._stop_event = threading.Event()
        self._sleep_time = sleep_time
        """call base class constructor"""
        super().__init__()

    def run(self):
        """main control loop"""
        while not self._stop_event.isSet():
            #do work
            print("hi")
            self._stop_event.wait(self._sleep_time)

    def join(self, timeout=None):
        """set stop event and join within a given time period"""
        self._stop_event.set()
        super().join(timeout)


if __name__ == "__main__":
    t = MyThread()
    t.start()

    time.sleep(5)

    t.join(1) #wait 1s max

Having a small sleep inside the main loop before checking the threading.Event is less CPU intensive than looping continuously. You can have a default sleep time (e.g. 0.1s), but you can also pass the value in the constructor.

Why not using: SELECT home, MAX(datetime) AS MaxDateTime,player,resource FROM topten GROUP BY home Did I miss something?

I also need this to monitor the network issue for my database mirroring time out issue. I use the command code as below:

ping -t Google.com|cmd /q /v /c "(pause&pause)>nul & for /l %a in () do (set /p "data=" && echo(!date! !time! !data!)&ping -n 2 Google.com>nul" >C:\pingtest.txt

You just need to modify Google.com to your server name. It works perfectly for me. and remember to stop this when you finished. The pingtest.txt file will increase by 1 KB per second (around).

Thank for raymond.cc. https://www.raymond.cc/blog/timestamp-ping-with-hrping/

Throwable is super class of Exception as well as Error. In normal cases we should always catch sub-classes of Exception, so that the root cause doesn't get lost.

Only special cases where you see possibility of things going wrong which is not in control of your Java code, you should catch Error or Throwable.

I remember catching Throwable to flag that a native library is not loaded.

I know this was asked awhile back, but I found a comprehensive list of the virtual keyboard key codes right in MSDN, for use in C/C++. This also includes the mouse events. Note it is different than the javascript key codes (I noticed it around the VK_OEM section).

To change the Prevent saving changes that require the table re-creation option, follow these steps:

Open SQL Server Management Studio (SSMS). On the Tools menu, click Options.

In the navigation pane of the Options window, click Designers.

Select or clear the Prevent saving changes that require the table re-creation check box, and then click OK.

Note: If you disable this option, you are not warned when you save the table that the changes that you made have changed the metadata structure of the table. In this case, data loss may occur when you save the table.

Not sure if I get you right, but the simplest way would be something like:

<c:if test="${languageBean.locale == 'en'">
  <f:selectItems value="#{customerBean.selectableCommands_limited_en}" />
</c:if>

uint8, uint16, uint32, and uint64 are probably Microsoft-specific types.

As of the 1999 standard, C supports standard typedefs with similar meanings, defined in <stdint.h>: uint8_t, uint16_t, uint32_t, and uint64_t. I'll assume that the Microsoft-specific types are defined similarly. Microsoft does support <stdint.h>, at least as of Visual Studio 2010, but older code may use uint8 et al.

The predefined types char, short, int et al have sizes that vary from one C implementation to another. The C standard has certain minimum requirements (char is at least 8 bits, short and int are at least 16, long is at least 32, and each type in that list is at least as wide as the previous type), but permits some flexibility. For example, I've seen systems where int is 16, 32, or 64 bits.

char is almost always exactly 8 bits, but it's permitted to be wider. And plain char may be either signed or unsigned.

uint8_t is required to be an unsigned integer type that's exactly 8 bits wide. It's likely to be a typedef for unsigned char, though it might be a typedef for plain char if plain char happens to be unsigned. If there is no predefined 8-bit unsigned type, then uint8_t will not be defined at all.

Similarly, each uintN_t type is an unsigned type that's exactly N bits wide.

In addition, <stdint.h> defines corresponding signed intN_t types, as well as int_fastN_t and int_leastN_t types that are at least the specified width.

The [u]intN_t types are guaranteed to have no padding bits, so the size of each is exactly N bits. The signed intN_t types are required to use a 2's-complement representation.

Although uint32_t might be the same as unsigned int, for example, you shouldn't assume that. Use unsigned int when you need an unsigned integer type that's at least 16 bits wide, and that's the "natural" size for the current system. Use uint32_t when you need an unsigned integer type that's exactly 32 bits wide.

(And no, uint64 or uint64_t is not the same as double; double is a floating-point type.)

Because there are two print statements. First is inside function and second is outside function. When function not return any thing that time it return None value.

Use return statement at end of function to return value.

e.g.:

Return None value.

>>> def test1():
...    print "In function."
... 
>>> a = test1()
In function.
>>> print a
None
>>> 
>>> print test1()
In function.
None
>>>
>>> test1()
In function.
>>> 

Use return statement

>>> def test():
...   return "ACV"
... 
>>> print test()
ACV
>>> 
>>> a = test()
>>> print a
ACV
>>> 

You can't.

The only way to set the value of a file input is by the user to select a file.

This is done for security reasons. Otherwise you would be able to create a JavaScript that automatically uploads a specific file from the client's computer.

Because the PermGen space was removed. Memory management has changed a bit.

You have what you have used in stored procedures like this for reference, but they are not intended to be used as you have now. You can use IF as shown by duskwuff. But a Case statement is better for eyes. Like this:

select id, 
    (
    CASE 
        WHEN qty_1 <= '23' THEN price
        WHEN '23' > qty_1 && qty_2 <= '23' THEN price_2
        WHEN '23' > qty_2 && qty_3 <= '23' THEN price_3
        WHEN '23' > qty_3 THEN price_4
        ELSE 1
    END) AS total
 from product;

This looks cleaner. I suppose you do not require the inner SELECT anyway..

If you just call exit in Bash without any parameters, it will return the exit code of the last command. Combined with OR, Bash should only invoke exit, if the previous command fails. But I haven't tested this.

command1 || exit;
command2 || exit;

Bash will also store the exit code of the last command in the variable $?.

The simple example presented on Wikipedia worked for me. (you can read the complete description at http://en.wikipedia.org/wiki/Circular_dependency#Example_of_circular_dependencies_in_C.2B.2B )

#endif //B_H

File '''main.cpp''':

You cannot in the same page's loading set and check if cookies is set you must perform reload page:

• PHP run at Server;
• cookies at client.
• cookies sent to server only during loading of a page.
• Just created cookies have not been sent to server yet and will be sent only at next load of the page.

If, like me, what you usually want is to overwrite the contents of the working directory with that of the stashed files, and you still get a conflict, then what you want is to resolve the conflict using git checkout --theirs -- . from the root.

After that, you can git reset to bring all the changes from the index to the working directory, since apparently in case of conflict the changes to non-conflicted files stay in the index.

You may also want to run git stash drop [<stash name>] afterwards, to get rid of the stash, because git stash pop doesn't delete it in case of conflicts.

You are using USCOUNTER in a subshell, that's why the variable is not showing in the main shell.

Instead of cat FILE | while ..., do just a while ... done < $FILE. This way, you avoid the common problem of I set variables in a loop that's in a pipeline. Why do they disappear after the loop terminates? Or, why can't I pipe data to read?:

while read country _; do
  if [ "US" = "$country" ]; then
        USCOUNTER=$(expr $USCOUNTER + 1)
        echo "US counter $USCOUNTER"
  fi
done < "$FILE"

Note I also replaced the `` expression with a $().

I also replaced while read line; do country=$(echo "$line" | cut -d' ' -f1) with while read country _. This allows you to say while read var1 var2 ... varN where var1 contains the first word in the line, $var2 and so on, until $varN containing the remaining content.

You can use the following library:

https://github.com/pnowy/NativeCriteria

The library is built on the top of the Hibernate "create sql query" so it supports all databases supported by Hibernate (the Hibernate session and JPA providers are supported). The builder patter is available and so on (object mappers, result mappers).

You can find the examples on github page, the library is available at Maven central of course.

NativeCriteria c = new NativeCriteria(new HibernateQueryProvider(hibernateSession), "table_name", "alias");
c.addJoin(NativeExps.innerJoin("table_name_to_join", "alias2", "alias.left_column", "alias2.right_column"));
c.setProjection(NativeExps.projection().addProjection(Lists.newArrayList("alias.table_column","alias2.table_column")));

Here goes mine, it's self contained and versatile, as well as efficient, it grows or shrinks buffers as needed in each recursion

void strreplace(char *src, char *str, char *rep)
{
    char *p = strstr(src, str);
    if (p)
    {
        int len = strlen(src)+strlen(rep)-strlen(str);
        char r[len];
        memset(r, 0, len);
        if ( p >= src ){
            strncpy(r, src, p-src);
            r[p-src]='\0';
            strncat(r, rep, strlen(rep));
            strncat(r, p+strlen(str), p+strlen(str)-src+strlen(src));
            strcpy(src, r);
            strreplace(p+strlen(rep), str, rep);
        }
    }
}

It can be cleaner to add an extension to FileManager for this kind of awkward call, for tidiness if nothing else. Something like:

extension FileManager {
    static var documentDir : URL {
        return FileManager.default.urls(for: .documentDirectory, in: .userDomainMask).first!
    }
}

Let's discuss why an "object not found" error can be thrown in R in addition to explaining what it means. What it means (to many) is obvious: the variable in question, at least according to the R interpreter, has not yet been defined, but if you see your object in your code there can be multiple reasons for why this is happening:

1. check syntax of your declarations. If you mis-typed even one letter or used upper case instead of lower case in a later calling statement, then it won't match your original declaration and this error will occur.

2. Are you getting this error in a notebook or markdown document? You may simply need to re-run an earlier cell that has your declarations before running the current cell where you are calling the variable.

3. Are you trying to knit your R document and the variable works find when you run the cells but not when you knit the cells? If so - then you want to examine the snippet I am providing below for a possible side effect that triggers this error:

   {r sourceDataProb1, echo=F, eval=F} # some code here

The above snippet is from the beginning of an R markdown cell. If eval and echo are both set to False this can trigger an error when you try to knit the document. To clarify. I had a use case where I had left these flags as False because I thought i did not want my code echoed or its results to show in the markdown HTML I was generating. But since the variable was then used in later cells, this caused an error during knitting. Simple trial and error with T/F TRUE/FALSE flags can establish if this is the source of your error when it occurs in knitting an R markdown document from RStudio.

Lastly: did you remove the variable or clear it from memory after declaring it?

• rm() removes the variable
• hitting the broom icon in the evironment window of RStudio clearls everything in the current working environment
• ls() can help you see what is active right now to look for a missing declaration.
• exists("x") - as mentioned by another poster, can help you test a specific value in an environment with a very lengthy list of active variables

This seems to be premature microoptimization. The compiler is free to produce the same code for both cases or at least for these two

if len(s) != 0 { ... }

and

if s != "" { ... }

because the semantics is clearly equal.

If you have a list of hashable objects (filenames would probably be strings, so they should count):

lst = ['foo.py', 'bar.py', 'baz.py', 'qux.py', Ellipsis]

you can construct the set directly:

s = set(lst)

In fact, set will work this way with any iterable object! (Isn't duck typing great?)

If you want to do it iteratively:

s = set()
for item in iterable:
    s.add(item)

But there's rarely a need to do it this way. I only mention it because the set.add method is quite useful.

if(map.get(key) != null || (map.get(key) == null && map.containsKey(key)))

No, as of Notepad++ 5.6.2, this doesn't seem to be possible. Although column selection (Alt+Selection) is possible, multiple selections are obviously not implemented and thus also not supported by the search function.

public class Program {
    public static void main(String[] args) {
        String text = "Hello world";
        BufferedWriter output = null;
        try {
            File file = new File("example.txt");
            output = new BufferedWriter(new FileWriter(file));
            output.write(text);
        } catch ( IOException e ) {
            e.printStackTrace();
        } finally {
          if ( output != null ) {
            output.close();
          }
        }
    }
}

Here is the clear example of creating array of 10 employee objects, with a constructor that takes parameter:

public class MainClass
{  
    public static void main(String args[])
    {
        System.out.println("Hello, World!");
        //step1 : first create array of 10 elements that holds object addresses.
        Emp[] employees = new Emp[10];
        //step2 : now create objects in a loop.
        for(int i=0; i<employees.length; i++){
            employees[i] = new Emp(i+1);//this will call constructor.
        }
    }
}

class Emp{
    int eno;
    public Emp(int no){
        eno = no;
        System.out.println("emp constructor called..eno is.."+eno);
    }
}

What's with separating My Documents from C:\test-backup? And why the quotes only around My Documents?

I'm assuming it's a typo, try using robocopy C:\Users\Angie "C:\test-backup\My Documents" /B /E /R:0 /CREATE /NP /TEE /XJ /LOG+:"CompleteBackupLog.txt"

[Edit:] Since the syntax the documentation specifies (robocopy <Source> <Destination> [<File>[ ...]]) says File, it might not work with Folders.

You'll have to userobocopy "C:\Users\Angie\My Documents" "C:\test-backup\My Documents" /B /E /R:0 /CREATE /NP /TEE /XJ /LOG+:"CompleteBackupLog.txt"

Bit late to this...I'm surprised that no one mentioned Symfony's VarDumper component that Laravel includes, in part, for its dd() (and lesser-known, dump()) utility functions.

$dumpMe = new App\User([ 'name' => 'Cy Rossignol' ]);

(new Symfony\Component\VarDumper\Dumper\CliDumper())->dump( 
    (new Symfony\Component\VarDumper\Cloner\VarCloner())->cloneVar($dumpMe)
);

There's a bit more code needed, but, in return, we get nice formatted, readable output in the console—especially useful for debugging complex objects or arrays:

App\User {#17
  #attributes: array:1 [
    "name" => "Cy Rossignol"
  ]
  #fillable: array:3 [
    0 => "name"
    1 => "email"
    2 => "password"
  ]
  #guarded: array:1 [
    0 => "*"
  ]
  #primaryKey: "id"
  #casts: []
  #dates: []
  #relations: []
  ... etc ...
}

To take this a step further, we can even colorize the output! Add this helper function to the project to save some typing:

function toConsole($var) 
{
    $dumper = new Symfony\Component\VarDumper\Dumper\CliDumper();
    $dumper->setColors(true);

    $dumper->dump((new Symfony\Component\VarDumper\Cloner\VarCloner())->cloneVar($var));
}

If we're running the app behind a full webserver (like Apache or Nginx—not artisan serve), we can modify this function slightly to send the dumper's prettified output to the log (typically storage/logs/laravel.log):

function toLog($var) 
{
    $lines = [ 'Dump:' ];
    $dumper = new Symfony\Component\VarDumper\Dumper\CliDumper();
    $dumper->setColors(true);
    $dumper->setOutput(function ($line) use (&$lines) { 
        $lines[] = $line;
    });

    $dumper->dump((new Symfony\Component\VarDumper\Cloner\VarCloner())->cloneVar($var));

    Log::debug(implode(PHP_EOL, $lines));
}

...and, of course, watch the log using:

$ tail -f storage/logs/laravel.log

PHP's error_log() works fine for quick, one-off inspection of simple values, but the functions shown above take the hard work out of debugging some of Laravel's more complicated classes.

I want to expand on this answer. What they meant is this icon:

It opens a "real editor window" instead of the limited-feature text box in the big overview. In that editor window, special chars, linebreaks etc. are allowed and converted to the correct xml "code" when saved

=ROUND((TODAY()-A1)/365,0) will provide number of years between date in cell A1 and today's date
