There is a Date function.

As my usecase involves dozens of columns, I expanded @jahroy's answer a bit. (also just realized @charles-clayton had the same idea.)
I pass the parameter I want to sort by, and the sort function is redefined with the desired index for the comparison to take place on.

var ID_COLUMN=0
var URL_COLUMN=1

findings.sort(compareByColumnIndex(URL_COLUMN))

function compareByColumnIndex(index) {
  return function(a,b){
    if (a[index] === b[index]) {
        return 0;
    }
    else {
        return (a[index] < b[index]) ? -1 : 1;
    }
  }
}

UPDATE - I do not have Total DNS enabled at GoDaddy because the domain is hosted at DiscountASP. As such, I could not add an A Record and that is why GoDaddy was only offering to forward my subdomain to a different site. I finally realized that I had to go to DiscountASP to add the A Record to point to DreamHost. Now waiting to see if it all works!

Of course, use the stinkin' IP! I'm not sure why that wasn't registering for me. I guess their helper text example of pointing to another url was throwing me off.

Thanks for both of the replies. I 'got it' as soon as I read Bryant's response which was first but Saif kicked it up a notch and added a little more detail.

Thanks!

For me, the answers previously provided here, were opening a new tab/window (probably because of my browser settings). But i wanted to reload/refresh on the same page. So, the above solutions did not work for me.

However, the good news is, the following (either of two) worked for me.

1. <a onclick="javascript:window.location.reload();"> refresh</a>
2. <a onclick="window.location.href=this">refresh</a>

I have tried the solution which redirects 405 to 200, and in production environment(in my case, it's Google Load Balancing with Nginx Docker container), this hack causes some 502 errors(Google Load Balancing error code: backend_early_response_with_non_error_status).

In the end, I have made this work properly by replacing Nginx with OpenResty which is completely compatible with Nginx and have more plugins.

With ngx_coolkit, Now Nginx(OpenResty) could serve static files with POST request properly, here is the config file in my case:

server {
  listen 80;

  location / {
    override_method GET;
    proxy_pass http://127.0.0.1:8080;
  }
}

server {
  listen 8080;
  location / {
    root /var/www/web-static;
    index index.html;
    add_header Cache-Control no-cache;
  }
}

In the above config, I use override_method offered by ngx_coolkit to override the HTTP Method to GET.

This:

document.getElementById('myField').onblur();

works because your element (the <input>) has an attribute called "onblur" whose value is a function. Thus, you can call it. You're not telling the browser to simulate the actual "blur" event, however; there's no event object created, for example.

Elements do not have a "blur" attribute (or "method" or whatever), so that's why the first thing doesn't work.

The action occurs when you attempt to call an object which is not a function, as with (). For instance, this will produce the error:

>>> a = 5
>>> a()
Traceback (most recent call last):
  File "<stdin>", line 1, in <module>
TypeError: 'int' object is not callable

Class instances can also be called if they define a method __call__

One common mistake that causes this error is trying to look up a list or dictionary element, but using parentheses instead of square brackets, i.e. (0) instead of [0]

char a[2] defines an array of char's. a is a pointer to the memory at the beginning of the array and using == won't actually compare the contents of a with 'ab' because they aren't actually the same types, 'ab' is integer type. Also 'ab' should be "ab" otherwise you'll have problems here too. To compare arrays of char you'd want to use strcmp.

Something that might be illustrative is looking at the typeid of 'ab':

#include <iostream>
#include <typeinfo>
using namespace std;
int main(){
    int some_int =5;
    std::cout << typeid('ab').name() << std::endl;
    std::cout << typeid(some_int).name() << std::endl;
    return 0;
}

on my system this returns:

i
i

showing that 'ab' is actually evaluated as an int.

If you were to do the same thing with a std::string then you would be dealing with a class and std::string has operator == overloaded and will do a comparison check when called this way.

If you wish to compare the input with the string "ab" in an idiomatic c++ way I suggest you do it like so:

#include <iostream>
#include <string>
using namespace std;
int main(){
    string a;
    cout<<"enter ab ";
    cin>>a;
    if(a=="ab"){
         cout<<"correct";
    }
    return 0;
}

This one is due to:

if(a=='ab') , here, a is const char* type (ie : array of char)

'ab' is a constant value,which isn't evaluated as string (because of single quote) but will be evaluated as integer.

Since char is a primitive type inherited from C, no operator == is defined.

the good code should be:

if(strcmp(a,"ab")==0) , then you'll compare a const char* to another const char* using strcmp.

Open youtube video. Click on share option. In share option click on embed tag. You can see in embed tag there is some check box. Unchecked on show video title and player actions. After this just copy frame tag.

I would like to say that you must always use jQuery latest or recent stable versions. However if you need to do some work with others versions then you can add that version and renamed the $ to some other name. For instance

<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js" type="text/javascript"></script>
<script src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js" type="text/javascript"></script>
<script>var $oldjQuery = $.noConflict(true);</script>

Look here if you write something using $ then you will get the latest version. But if you need to do anything with old then just use$oldjQuery instead of $.

Here is an example

$(function(){console.log($.fn.jquery)});
$oldjQuery (function(){console.log($oldjQuery.fn.jquery)})

Mallocs and frees need to be paired up.

malloc grabbed a chunk of memory big enough for Person.

When you free you tell malloc the piece of memory starting "here" is no longer needed, it knows how much it allocated and frees it.

Whether you call

 free(testPerson) 

or

 free(testPerson->firstName)

all that free() actually receives is an address, the same address, it can't tell which you called. Your code is much clearer if you use free(testPerson) though - it clearly matches up the with malloc.

I have been using csvreader.com(paid component) for years, and I have never had a problem. It is solid, small and fast, but you do have to pay for it. You can set the delimiter to whatever you like.

using (CsvReader reader = new CsvReader(s) {
    reader.Settings.Delimiter = ';';
    reader.ReadHeaders();  // if headers on a line by themselves.  Makes reader.Headers[] available
    while (reader.ReadRecord())
        ... use reader.Values[col_i] ...
}

Currently it only works for the .dropdown-menu:

.dropdown-menu .divider {
  height: 1px;
  margin: 9px 0;
  overflow: hidden;
  background-color: #e5e5e5;
}

If you want it for other use, in your own css, following the bootstrap.css create another one:

.divider {
  height: 1px;
  width:100%;
  display:block; /* for use on default inline elements like span */
  margin: 9px 0;
  overflow: hidden;
  background-color: #e5e5e5;
}

Create a shortcut to your bat file by using the right-click and selecting Create shortcut. Right-click on the shortcut you created and click on properties. Click on the Run drop-down box and select Minimized.

You can use array_agg function for that:

SELECT "Movie",
array_to_string(array_agg(distinct "Actor"),',') AS Actor
FROM Table1
GROUP BY "Movie";

finally solved my problem.

I created a new project in XCode with the sources and changed the C++ Standard Library from the default libc++ to libstdc++ as in this and this.

I've created a tiny utility called super-array where you can access items in an array by a unique identifier with O(1) complexity. Example:

const SuperArray = require('super-array');

const myArray = new SuperArray([
  {id: 'ab1', name: 'John'},
  {id: 'ab2', name: 'Peter'},
]);

console.log(myArray.get('ab1')); // {id: 'ab1', name: 'John'}
console.log(myArray.get('ab2')); // {id: 'ab2', name: 'Peter'}

Your regex should work 'as-is'. Assuming that it is doing what you want it to.

wordA(\s*)wordB(?! wordc)

This means match wordA followed by 0 or more spaces followed by wordB, but do not match if followed by wordc. Note the single space between ?! and wordc which means that wordA wordB wordc will not match, but wordA wordB wordc will.

Here are some example matches and the associated replacement output:

Note that all matches are replaced no matter how many spaces. There are a couple of other points: -

• (?! wordc) is a negative lookahead, so you wont match lines wordA wordB wordc which is assume is intended (and is why the last line is not matched). Currently you are relying on the space after ?! to match the whitespace. You may want to be more precise and use (?!\swordc). If you want to match against more than one space before wordc you can use (?!\s*wordc) for 0 or more spaces or (?!\s*+wordc) for 1 or more spaces depending on what your intention is. Of course, if you do want to match lines with wordc after wordB then you shouldn't use a negative lookahead.

• * will match 0 or more spaces so it will match wordAwordB. You may want to consider + if you want at least one space.

• (\s*) - the brackets indicate a capturing group. Are you capturing the whitespace to a group for a reason? If not you could just remove the brackets, i.e. just use \s.

Update based on comment

Hello the problem is not the expression but the HTML out put   that are not considered as whitespace. it's a Joomla website.

Preserving your original regex you can use:

wordA((?:\s| )*)wordB(?!(?:\s| )wordc)

The only difference is that not the regex matches whitespace OR  . I replaced wordc with \swordc since that is more explicit. Note as I have already pointed out that the negative lookahead ?! will not match when wordB is followed by a single whitespace and wordc. If you want to match multiple whitespaces then see my comments above. I also preserved the capture group around the whitespace, if you don't want this then remove the brackets as already described above.

Example matches:

Elaborating on the answer provided by Brian R. Bondy: Here's an example that shows why you can't simply size the output buffer to the number of wide characters in the source string:

#include <windows.h>
#include <stdio.h>
#include <wchar.h>
#include <string.h>

/* string consisting of several Asian characters */
wchar_t wcsString[] = L"\u9580\u961c\u9640\u963f\u963b\u9644";

int main() 
{

    size_t wcsChars = wcslen( wcsString);

    size_t sizeRequired = WideCharToMultiByte( 950, 0, wcsString, -1, 
                                               NULL, 0,  NULL, NULL);

    printf( "Wide chars in wcsString: %u\n", wcsChars);
    printf( "Bytes required for CP950 encoding (excluding NUL terminator): %u\n",
             sizeRequired-1);

    sizeRequired = WideCharToMultiByte( CP_UTF8, 0, wcsString, -1,
                                        NULL, 0,  NULL, NULL);
    printf( "Bytes required for UTF8 encoding (excluding NUL terminator): %u\n",
             sizeRequired-1);
}

And the output:

Wide chars in wcsString: 6
Bytes required for CP950 encoding (excluding NUL terminator): 12
Bytes required for UTF8 encoding (excluding NUL terminator): 18

The simplest if you want to use only builtins is probably:

find `pwd` -name fileName

Only an extra two words to type, and this will work on all unix systems, as well as OSX.

Date has the time as well, just add HH:mm:ss to the date format:

import java.text.SimpleDateFormat
def date = new Date()
def sdf = new SimpleDateFormat("MM/dd/yyyy HH:mm:ss")
println sdf.format(date)

In case you are using JRE 8 you can use LoaclDateTime:

import java.time.*

LocalDateTime t = LocalDateTime.now();
return t as String

Historical Note: This was written at the time of PHP4. This is what we call "legacy code" now.

I have left this answer for historical purposes - but some of the methods are now deprecated, DES encryption method is not a recommended practice, etc.

I have not updated this code for two reasons: 1) I no longer work with encryption methods by hand in PHP, and 2) this code still serves the purpose it was intended for: to demonstrate the minimum, simplistic concept of how encryption can work in PHP.

If you find a similarly simplistic, "PHP encryption for dummies" kind of source that can get people started in 10-20 lines of code or less, let me know in comments.

Beyond that, please enjoy this Classic Episode of early-era PHP4 minimalistic encryption answer.

Ideally you have - or can get - access to the mcrypt PHP library, as its certainly popular and very useful a variety of tasks. Here's a run down of the different kinds of encryption and some example code: Encryption Techniques in PHP

//Listing 3: Encrypting Data Using the mcrypt_ecb Function 

<?php 
echo("<h3> Symmetric Encryption </h3>"); 
$key_value = "KEYVALUE"; 
$plain_text = "PLAINTEXT"; 
$encrypted_text = mcrypt_ecb(MCRYPT_DES, $key_value, $plain_text, MCRYPT_ENCRYPT); 
echo ("<p><b> Text after encryption : </b>"); 
echo ( $encrypted_text ); 
$decrypted_text = mcrypt_ecb(MCRYPT_DES, $key_value, $encrypted_text, MCRYPT_DECRYPT); 
echo ("<p><b> Text after decryption : </b>"); 
echo ( $decrypted_text ); 
?> 

A few warnings:

1) Never use reversible, or "symmetric" encryption when a one-way hash will do.

2) If the data is truly sensitive, like credit card or social security numbers, stop; you need more than any simple chunk of code will provide, but rather you need a crypto library designed for this purpose and a significant amount of time to research the methods necessary. Further, the software crypto is probably <10% of security of sensitive data. It's like rewiring a nuclear power station - accept that the task is dangerous and difficult and beyond your knowledge if that's the case. The financial penalties can be immense, so better to use a service and ship responsibility to them.

3) Any sort of easily implementable encryption, as listed here, can reasonably protect mildly important information that you want to keep from prying eyes or limit exposure in the case of accidental/intentional leak. But seeing as how the key is stored in plain text on the web server, if they can get the data they can get the decryption key.

Be that as it may, have fun :)

ESC and CTRL-BREAK did not work for me just now. But CTRL-ESC worked!? No idea why, but I thought I would throw it out there in case it helps someone else. (I had forgotten i = i + 1 in my loop...)

If a case-insensitive comparison is acceptable, just use =:

=IF(A1="ENG",1,0)

You can use markersize to specify the size of the circle in plot method

import numpy as np
import matplotlib.pyplot as plt

x1 = np.random.randn(20)
x2 = np.random.randn(20)
plt.figure(1)
# you can specify the marker size two ways directly:
plt.plot(x1, 'bo', markersize=20)  # blue circle with size 10 
plt.plot(x2, 'ro', ms=10,)  # ms is just an alias for markersize
plt.show()

From here

Can also do it by regex:

Pattern queryLangPattern = Pattern.compile("true|false", Pattern.CASE_INSENSITIVE);
Matcher matcher = queryLangPattern.matcher(booleanParam);
return matcher.matches();

Meder Omuraliev suggested to use an event handler and set scrollTo(0,0). This is an example for Wassim-azirar. Bringing it all together, I assume this is the final solution.

We have 3 problems: the scrollbar, scrolling with mouse, and keyboard. This hides the scrollbar:

       html, body{overflow:hidden;}

Unfortunally, you can still scroll with the keyboard: To prevent this, we can:

    function keydownHandler(e) {
var evt = e ? e:event;
  var keyCode = evt.keyCode;

  if (keyCode==38 || keyCode==39 || keyCode==40 || keyCode==37){ //arrow keys
e.preventDefault()
scrollTo(0,0);
}
}

document.onkeydown=keydownHandler;

The scrolling with the mouse just naturally doesn't work after this code, so we have prevented the scrolling.

For example: https://jsfiddle.net/aL7pes70/1/

To get it done only with XAML you need to add Validation Rules for individual properties. But i would recommend you to go with code behind approach. In your code, define your specifications in properties setters and throw exceptions when ever it doesn't compliance to your specifications. And use error template to display your errors to user in UI. Your XAML will look like this

<Window x:Class="WpfApplication1.MainWindow"

    xmlns:x="http://schemas.microsoft.com/winfx/2006/xaml"

    <Style x:Key="CustomTextBoxTextStyle" TargetType="TextBox">
        <Setter Property="Foreground" Value="Green" />
        <Setter Property="MaxLength" Value="40" />
        <Setter Property="Width" Value="392" />
        <Style.Triggers>
            <Trigger Property="Validation.HasError" Value="True">
                <Trigger.Setters>
                    <Setter Property="ToolTip" Value="{Binding RelativeSource={RelativeSource Self},Path=(Validation.Errors)[0].ErrorContent}"/>
                    <Setter Property="Background" Value="Red"/>
                </Trigger.Setters>

Improved @haitaka answer, using the key and predicate

function  deepSearch (object, key, predicate) {
    if (object.hasOwnProperty(key) && predicate(key, object[key]) === true) return object

    for (let i = 0; i < Object.keys(object).length; i++) {
      let value = object[Object.keys(object)[i]];
      if (typeof value === "object" && value != null) {
        let o = deepSearch(object[Object.keys(object)[i]], key, predicate)
        if (o != null) return o
      }
    }
    return null
}

So this can be invoked as:

var result = deepSearch(myObject, 'id', (k, v) => v === 1);

or

var result = deepSearch(myObject, 'title', (k, v) => v === 'Some Recommends');

Here is the demo: http://jsfiddle.net/a21dx6c0/

EDITED

In the same way you can find more than one object

function deepSearchItems(object, key, predicate) {
        let ret = [];
        if (object.hasOwnProperty(key) && predicate(key, object[key]) === true) {
            ret = [...ret, object];
        }
        if (Object.keys(object).length) {
            for (let i = 0; i < Object.keys(object).length; i++) {
                let value = object[Object.keys(object)[i]];
                if (typeof value === "object" && value != null) {
                    let o = this.deepSearchItems(object[Object.keys(object)[i]], key, predicate);
                    if (o != null && o instanceof Array) {
                        ret = [...ret, ...o];
                    }
                }
            }
        }
        return ret;
    }

What is wrong with this approach? Why would I want to use Redux Thunk or Redux Promise, as the documentation suggests?

There is nothing wrong with this approach. It’s just inconvenient in a large application because you’ll have different components performing the same actions, you might want to debounce some actions, or keep some local state like auto-incrementing IDs close to action creators, etc. So it is just easier from the maintenance point of view to extract action creators into separate functions.

You can read my answer to “How to dispatch a Redux action with a timeout” for a more detailed walkthrough.

Middleware like Redux Thunk or Redux Promise just gives you “syntax sugar” for dispatching thunks or promises, but you don’t have to use it.

So, without any middleware, your action creator might look like

// action creator
function loadData(dispatch, userId) { // needs to dispatch, so it is first argument
  return fetch(`http://data.com/${userId}`)
    .then(res => res.json())
    .then(
      data => dispatch({ type: 'LOAD_DATA_SUCCESS', data }),
      err => dispatch({ type: 'LOAD_DATA_FAILURE', err })
    );
}

// component
componentWillMount() {
  loadData(this.props.dispatch, this.props.userId); // don't forget to pass dispatch
}

But with Thunk Middleware you can write it like this:

// action creator
function loadData(userId) {
  return dispatch => fetch(`http://data.com/${userId}`) // Redux Thunk handles these
    .then(res => res.json())
    .then(
      data => dispatch({ type: 'LOAD_DATA_SUCCESS', data }),
      err => dispatch({ type: 'LOAD_DATA_FAILURE', err })
    );
}

// component
componentWillMount() {
  this.props.dispatch(loadData(this.props.userId)); // dispatch like you usually do
}

So there is no huge difference. One thing I like about the latter approach is that the component doesn’t care that the action creator is async. It just calls dispatch normally, it can also use mapDispatchToProps to bind such action creator with a short syntax, etc. The components don’t know how action creators are implemented, and you can switch between different async approaches (Redux Thunk, Redux Promise, Redux Saga) without changing the components. On the other hand, with the former, explicit approach, your components know exactly that a specific call is async, and needs dispatch to be passed by some convention (for example, as a sync parameter).

Also think about how this code will change. Say we want to have a second data loading function, and to combine them in a single action creator.

With the first approach we need to be mindful of what kind of action creator we are calling:

// action creators
function loadSomeData(dispatch, userId) {
  return fetch(`http://data.com/${userId}`)
    .then(res => res.json())
    .then(
      data => dispatch({ type: 'LOAD_SOME_DATA_SUCCESS', data }),
      err => dispatch({ type: 'LOAD_SOME_DATA_FAILURE', err })
    );
}
function loadOtherData(dispatch, userId) {
  return fetch(`http://data.com/${userId}`)
    .then(res => res.json())
    .then(
      data => dispatch({ type: 'LOAD_OTHER_DATA_SUCCESS', data }),
      err => dispatch({ type: 'LOAD_OTHER_DATA_FAILURE', err })
    );
}
function loadAllData(dispatch, userId) {
  return Promise.all(
    loadSomeData(dispatch, userId), // pass dispatch first: it's async
    loadOtherData(dispatch, userId) // pass dispatch first: it's async
  );
}


// component
componentWillMount() {
  loadAllData(this.props.dispatch, this.props.userId); // pass dispatch first
}

With Redux Thunk action creators can dispatch the result of other action creators and not even think whether those are synchronous or asynchronous:

// action creators
function loadSomeData(userId) {
  return dispatch => fetch(`http://data.com/${userId}`)
    .then(res => res.json())
    .then(
      data => dispatch({ type: 'LOAD_SOME_DATA_SUCCESS', data }),
      err => dispatch({ type: 'LOAD_SOME_DATA_FAILURE', err })
    );
}
function loadOtherData(userId) {
  return dispatch => fetch(`http://data.com/${userId}`)
    .then(res => res.json())
    .then(
      data => dispatch({ type: 'LOAD_OTHER_DATA_SUCCESS', data }),
      err => dispatch({ type: 'LOAD_OTHER_DATA_FAILURE', err })
    );
}
function loadAllData(userId) {
  return dispatch => Promise.all(
    dispatch(loadSomeData(userId)), // just dispatch normally!
    dispatch(loadOtherData(userId)) // just dispatch normally!
  );
}


// component
componentWillMount() {
  this.props.dispatch(loadAllData(this.props.userId)); // just dispatch normally!
}

With this approach, if you later want your action creators to look into current Redux state, you can just use the second getState argument passed to the thunks without modifying the calling code at all:

function loadSomeData(userId) {
  // Thanks to Redux Thunk I can use getState() here without changing callers
  return (dispatch, getState) => {
    if (getState().data[userId].isLoaded) {
      return Promise.resolve();
    }

    fetch(`http://data.com/${userId}`)
      .then(res => res.json())
      .then(
        data => dispatch({ type: 'LOAD_SOME_DATA_SUCCESS', data }),
        err => dispatch({ type: 'LOAD_SOME_DATA_FAILURE', err })
      );
  }
}

If you need to change it to be synchronous, you can also do this without changing any calling code:

// I can change it to be a regular action creator without touching callers
function loadSomeData(userId) {
  return {
    type: 'LOAD_SOME_DATA_SUCCESS',
    data: localStorage.getItem('my-data')
  }
}

So the benefit of using middleware like Redux Thunk or Redux Promise is that components aren’t aware of how action creators are implemented, and whether they care about Redux state, whether they are synchronous or asynchronous, and whether or not they call other action creators. The downside is a little bit of indirection, but we believe it’s worth it in real applications.

Finally, Redux Thunk and friends is just one possible approach to asynchronous requests in Redux apps. Another interesting approach is Redux Saga which lets you define long-running daemons (“sagas”) that take actions as they come, and transform or perform requests before outputting actions. This moves the logic from action creators into sagas. You might want to check it out, and later pick what suits you the most.

I searched the Redux repo for clues, and found that Action Creators were required to be pure functions in the past.

This is incorrect. The docs said this, but the docs were wrong.
Action creators were never required to be pure functions.
We fixed the docs to reflect that.

As an alternative to sun.misc.BASE64Decoder or non-core libraries, look at javax.mail.internet.MimeUtility.decode().

public static byte[] encode(byte[] b) throws Exception {
    ByteArrayOutputStream baos = new ByteArrayOutputStream();
    OutputStream b64os = MimeUtility.encode(baos, "base64");
    b64os.write(b);
    b64os.close();
    return baos.toByteArray();
}
public static byte[] decode(byte[] b) throws Exception {
    ByteArrayInputStream bais = new ByteArrayInputStream(b);
    InputStream b64is = MimeUtility.decode(bais, "base64");
    byte[] tmp = new byte[b.length];
    int n = b64is.read(tmp);
    byte[] res = new byte[n];
    System.arraycopy(tmp, 0, res, 0, n);
    return res;
}

You can also use custom path:

slow_query_log = 1
slow_query_log_file = "C:/slowquery.log"

#Set General Log

That's perfectly normal. If you want gulp-cli available on the command line, you need to install it globally.

npm install --global gulp-cli

See the install instruction.

Also, node_modules/.bin/ isn't in your $PATH. But it is automatically added by npm when running npm scripts (see this blog post for reference).

So you could add scripts to your package.json file:

{
    "name": "your-app",
    "version": "0.0.1",
    "scripts": {
        "gulp": "gulp",
        "minify": "gulp minify"
    }
}

You could then run npm run gulp or npm run minify to launch gulp tasks.

maybe you can use jqmodal,it's lightweight and easy to use. you can show the modal box by calling

$('.box').jqmShow() 

Try this:

body { 
    min-height:100%; 
    background:red; 
} 

#some_div {
    min-height:100%; 
    background:black; 
} 

IE6 and earlier versions do not support the min-height property.

I think the problem is that when you tell the body to have a height of 100%, it's background can only be as tall as the hieght of one browser "viewport" (the viewing area that excludes the browsers toolbars & statusbars & menubars and the window edges). If the content is taller than one viewport, it will overflow the height devoted to the background.

This min-height property on the body should FORCE the background to be at least as tall as one viewport if your content does not fill one whole page down to the bottom, yet it should also let it grow downwards to encompass more interior content.

Try using the BackgroundWorker class. You give it delegates for what to run, and to be notified when work has finished. There is an example on the MSDN page that I linked to.

Simple quick to solve this problem is using IcePick

First, setup the library in app/build.gradle

repositories {
  maven {url "https://clojars.org/repo/"}
}
dependencies {
  compile 'frankiesardo:icepick:3.2.0'
  provided 'frankiesardo:icepick-processor:3.2.0'
}

Now, let's check this example below how to save state in Activity

public class ExampleActivity extends Activity {
  @State String username; // This will be automatically saved and restored

  @Override public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    Icepick.restoreInstanceState(this, savedInstanceState);
  }

  @Override public void onSaveInstanceState(Bundle outState) {
    super.onSaveInstanceState(outState);
    Icepick.saveInstanceState(this, outState);
  }
}

It works for Activities, Fragments or any object that needs to serialize its state on a Bundle (e.g. mortar's ViewPresenters)

Icepick can also generate the instance state code for custom Views:

class CustomView extends View {
  @State int selectedPosition; // This will be automatically saved and restored

  @Override public Parcelable onSaveInstanceState() {
    return Icepick.saveInstanceState(this, super.onSaveInstanceState());
  }

  @Override public void onRestoreInstanceState(Parcelable state) {
    super.onRestoreInstanceState(Icepick.restoreInstanceState(this, state));
  }

  // You can put the calls to Icepick into a BaseCustomView and inherit from it
  // All Views extending this CustomView automatically have state saved/restored
}

The pygame documentation for mouse events is here. You can either use the pygame.mouse.get_pressed method in collaboration with the pygame.mouse.get_pos (if needed). But please use the mouse click event via a main event loop. The reason why the event loop is better is due to "short clicks". You may not notice these on normal machines, but computers that use tap-clicks on trackpads have excessively small click periods. Using the mouse events will prevent this.

EDIT: To perform pixel perfect collisions use pygame.sprite.collide_rect() found on their docs for sprites.

It sounds like you want an image button:

<input type="image" src="logg.png" name="saveForm" class="btTxt submit" id="saveForm" />

Alternatively, you can use CSS to make the existing submit button use your image as its background.

In any case, you don't want a separate <img /> element on the page.

In addition to all the answers above:

If you are on Android 6.0+ (API Level 23+) you have to explicitly ask for permission to access external storage. Simply having

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

in your manifest won't be enough. You also have actively request the permission in your activity:

//check for permission
if(ContextCompat.checkSelfPermission(this,
            Manifest.permission.READ_EXTERNAL_STORAGE) == PackageManager.PERMISSION_DENIED){
    //ask for permission
    requestPermissions(new String[]{Manifest.permission.READ_EXTERNAL_STORAGE}, READ_EXTERNAL_STORAGE_PERMISSION_CODE);
}

I recommend reading this: http://developer.android.com/training/permissions/requesting.html#perm-request

You will eventually be able to use

background-image: attr(data-image-src url);

but that is not implemented anywhere yet to my knowledge. In the above, url is an optional "type-or-unit" parameter to attr(). See https://drafts.csswg.org/css-values/#attr-notation.

To disable specific rules for file(s) inside folder(s), you need to use the "overrides" key of your .eslintrc config file.

For example, if you want to remove the following rules:

1. no-use-before-define
2. max-lines-per-function

For all files inside the following main directory:

/spec

You can add this to your .eslintrc file...

"overrides": [
  {
    "files": ["spec/**/*.js"],
    "rules": {
      "no-use-before-define": ["off"],
      "max-lines-per-function": ["off"]
    }
  }
]

Note that I used ** inside the spec/**/*.js glob, which means I am looking recursively for all subfolders inside the folder called spec and selecting all files that ends with js in order to remove the desired rules from them.

For creating arrays of class Objects you can use the java.util.ArrayList. to define an array:

public ArrayList<ClassName> arrayName;
arrayName = new ArrayList<ClassName>();

Assign values to the array:

arrayName.add(new ClassName(class parameters go here);

Read from the array:

ClassName variableName = arrayName.get(index);

Note:

variableName is a reference to the array meaning that manipulating variableName will manipulate arrayName

for loops:

//repeats for every value in the array
for (ClassName variableName : arrayName){
}
//Note that using this for loop prevents you from editing arrayName

for loop that allows you to edit arrayName (conventional for loop):

for (int i = 0; i < arrayName.size(); i++){
    //manipulate array here
}

The PIL distribution is mispackaged for egg installation.

You're not actually returning anything from your run_cmd function.

function run_cmd(cmd, args, done) {
    var spawn = require("child_process").spawn;
    var child = spawn(cmd, args);
    var result = { stdout: "" };
    child.stdout.on("data", function (data) {
            result.stdout += data;
    });
    child.stdout.on("end", function () {
            done();
    });
    return result;
}

> foo = run_cmd("ls", ["-al"], function () { console.log("done!"); });
{ stdout: '' }
done!
> foo.stdout
'total 28520...'

Works just fine. :)

Some time we have more spaces in between quotes, then use this approach

a = "   "
>>> bool(a)
True
>>> bool(a.strip())
False

if not a.strip():
    print("String is empty")
else:
    print("String is not empty")

You would need a mapping provider for MySQL. That is an extra thing the Entity Framework needs to make the magic happen. This blog talks about other mapping providers besides the one Microsoft is supplying. I haven't found any mentionings of MySQL.

You can only use switch-case on types castable to an int.

You could, however, define a std::map<std::string, std::function> dispatcher and use it like dispatcher[str]() to achieve same effect.

Both the databases and tables should have character set utf8mb4 and collation utf8mb4_unicode_ci.

When creating a new database you should use:

CREATE DATABASE mydb CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

If you have an existing database and you want to add support:

ALTER DATABASE database_name CHARACTER SET = utf8mb4 COLLATE = utf8mb4_unicode_ci;

You also need to set the correct character set and collation for your tables:

CREATE TABLE IF NOT EXISTS table_name (
    ...
) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE utf8mb4_unicode_ci;

or change it if you've got existing tables with a lot of data:

ALTER TABLE table_name CONVERT TO CHARACTER SET utf8mb4 COLLATE utf8mb4_unicode_ci;

Note that utf8_general_ci is no longer recommended best practice. See the related Q & A:

What's the difference between utf8_general_ci and utf8_unicode_ci on Stack Overflow.

To prevent JUnit from instantiating your test base class just make it

public abstract class MyTestBaseClass { ... whatever... }

(@Ignore reports it as ignored which I reserve for temporarily ignored tests.)

I like to use functional style, such as:

function href(url,txt) {
  return "<a href='" +url+ "'>" +txt+ "</a>"
}

function li(txt) {
  return "<li>" +txt+ "</li>"
}

function ul(arr) {
  return "<ul>" + arr.map(li).join("") + "</ul>"
}

document.write(
  ul(
    [
      href("http://url1","link1"),
      href("http://url2","link2"),
      href("http://url3","link3")
    ]
  )
)

This style looks readable and transparent. It leads to the creation of utilities which reduces repetition in code.

This also tends to use intermediate strings automatically.

in Swift 3, converted from illuminates answer.

override func setSelected(_ selected: Bool, animated: Bool) {
    super.setSelected(selected, animated: animated)
    if(selected) {
        self.selectionStyle = .none
        self.backgroundColor = UIColor.green
    } else {
        self.backgroundColor = UIColor.blue
    }
}

(however the view only changes once the selection is confirmed by releasing your finger)

Ensure these two and it should work:-

Fixes this issue on windows like a charm.

Try following code. It is working for me....

UPDATE TableOne 
SET 
field1 =(SELECT TableTwo.field1 FROM TableTwo WHERE TableOne.id=TableTwo.id),
field2 =(SELECT TableTwo.field2 FROM TableTwo WHERE TableOne.id=TableTwo.id)
WHERE TableOne.id = (SELECT  TableTwo.id 
                             FROM   TableTwo 
                             WHERE  TableOne.id = TableTwo.id) 

What worked for me (youtube-dl version 2018.03.03, ffprobe 0.5, no avprobe, 3.4.1-tessus, in Hi-Sierra/iMac) was:

brew install libav

(thanks to marciovsena's post on GitHub).

I saw elsewhere that libav might be deprecated in the future, but I'll worry about it when we get there.

DateTime inherits its equals method from AbstractInstant. It is implemented as such

public boolean equals(Object readableInstant) {     // must be to fulfil ReadableInstant contract     if (this == readableInstant) {         return true;     }     if (readableInstant instanceof ReadableInstant == false) {         return false;     }     ReadableInstant otherInstant = (ReadableInstant) readableInstant;     return         getMillis() == otherInstant.getMillis() &&         FieldUtils.equals(getChronology(), otherInstant.getChronology()); } 

Notice the last line comparing chronology. It's possible your instances' chronologies are different.

try kill -9 {processID}

To find the process ID you can use ps -ef | grep gedit

You can use dangerouslySetInnerHTML, e.g.

render: function() {
    return (
        <div className="content" dangerouslySetInnerHTML={{__html: thisIsMyCopy}}></div>
    );
}

Leaving out the parenthesis and simply calling 'setParameter' now works with at least Hibernate.

String jpql = "from A where name in :names";
Query q = em.createQuery(jpql);
q.setParameter("names", l);

Late answer, but I think it adds something new to this topic.

None of the previous answers has answered the original question. Some have attempted to justify the lack of a constant, while others have showed ways in which we can deal with the lack of the constant. But no one has provided a compelling justification for the benefit of the constant, so its lack is still not properly explained.

A constant would be useful because it would prevent certain code errors from going unnoticed.

Say that you have a large code base with hundreds of references to "". Someone modifies one of these while scrolling through the code and changes it to " ". Such a change would have a high chance of going unnoticed into production, at which point it might cause some issue whose source will be tricky to detect.

OTOH, a library constant named EMPTY, if subject to the same error, would generate a compiler error for something like EM PTY.

Defining your own constant is still better. Someone could still alter its initialization by mistake, but because of its wide use, the impact of such an error would be much harder to go unnoticed than an error in a single use case.

This is one of the general benefits that you get from using constants instead of literal values. People usually recognize that using a constant for a value used in dozens of places allows you to easily update that value in just one place. What is less often acknowledged is that this also prevents that value from being accidentally modified, because such a change would show everywhere. So, yes, "" is shorter than EMPTY, but EMPTY is safer to use than "".

So, coming back to the original question, we can only speculate that the language designers were probably not aware of this benefit of providing constants for literal values that are frequently used. Hopefully, we'll one day see string constants added in Java.

In case you have a local variable with the same name, you might want to use the globals() function.

globals()['your_global_var'] = 42

The last changed time comes with the assumption that the web server provides accurate information. Dynamically generated pages will likely return the time the page was viewed. However, static pages are expected to reflect actual file modification time.

This is propagated through the HTTP header Last-Modified. The Javascript trick by AZIRAR is clever and will display this value. Also, in Firefox going to Tools->Page Info will also display in the "Modified" field.

your break statement should break out of the for (in in 1:n).

Personally I am always wary with break statements and double check it by printing to the console to double check that I am in fact breaking out of the right loop. So before you test add the following statement, which will let you know if you break before it reaches the end. However, I have no idea how you are handling the variable n so I don't know if it would be helpful to you. Make a n some test value where you know before hand if it is supposed to break out or not before reaching n.

for (in in 1:n)
{
    if (in == n)         #add this statement
    {
        "sorry but the loop did not break"
    }

    id_novo <- new_table_df$ID[in]
    if(id_velho==id_novo)
    {
        break
    }
    else if(in == n)
    {
        sold_df <- rbind(sold_df,old_table_df[out,])
    }
}

List<String> sids = new ArrayList<String>();
List<String> lids = new ArrayList<String>();

String query = "SELECT rlink_id, COUNT(*)"
             + "FROM dbo.Locate  "
             + "GROUP BY rlink_id ";

Statement stmt = yourconnection.createStatement();
try {
    ResultSet rs4 = stmt.executeQuery(query);

    while (rs4.next()) {
        sids.add(rs4.getString(1));

Case 1: Don’t care about local changes

• Solution 1: Get the latest code and reset the code

  git fetch origin
  git reset --hard origin/[tag/branch/commit-id usually: master]
  

• Solution 2: Delete the folder and clone again :D

  rm -rf [project_folder]
  git clone [remote_repo]
  

Case 2: Care about local changes

• Solution 1: no conflicts with new-online version

  git fetch origin
  git status
  

  will report something like:

  Your branch is behind 'origin/master' by 1 commit, and can be fast-forwarded.
  

  Then get the latest version

  git pull
  

• Solution 2: conflicts with new-online version

  git fetch origin
  git status
  

  will report something like:

  error: Your local changes to the following files would be overwritten by merge:
      file_name
  Please, commit your changes or stash them before you can merge.
  Aborting
  

  Commit your local changes

  git add .
  git commit -m ‘Commit msg’
  

  Try to get the changes (will fail)

  git pull
  

  will report something like:

  Pull is not possible because you have unmerged files.
  Please, fix them up in the work tree, and then use 'git add/rm <file>'
  as appropriate to mark resolution, or use 'git commit -a'.
  

  Open the conflict file and fix the conflict. Then:

  git add .
  git commit -m ‘Fix conflicts’
  git pull
  

  will report something like:

  Already up-to-date.

I have faced same issue when creating signed apk from android studio. I just change little bit change on build.gradle file inside android {}

lintOptions {
        checkReleaseBuilds false
        abortOnError false
    }

Use this one:

Dim ws As Worksheet
Dim range1 As Range, rng As Range
'change Sheet1 to suit
Set ws = ThisWorkbook.Worksheets("Sheet1")

Set range1 = ws.Range("A1:A5")
Set rng = ws.Range("B1")

With rng.Validation
    .Delete 'delete previous validation
    .Add Type:=xlValidateList, AlertStyle:=xlValidAlertStop, _
        Formula1:="='" & ws.Name & "'!" & range1.Address
End With

Note that when you're using Dim range1, rng As range, only rng has type of Range, but range1 is Variant. That's why I'm using Dim range1 As Range, rng As Range.
About meaning of parameters you can read is MSDN, but in short:

• Type:=xlValidateList means validation type, in that case you should select value from list
• AlertStyle:=xlValidAlertStop specifies the icon used in message boxes displayed during validation. If user enters any value out of list, he/she would get error message.
• in your original code, Operator:= xlBetween is odd. It can be used only if two formulas are provided for validation.
• Formula1:="='" & ws.Name & "'!" & range1.Address for list data validation provides address of list with values (in format =Sheet!A1:A5)

To further complete @Ryan 's answer using json, one very convenient function to convert unicode is the one posted here: https://stackoverflow.com/a/13105359/7599285

ex with double or single quotes:

>print byteify(json.loads(u'[ "A","B","C" , " D"]')
>print byteify(json.loads(u"[ 'A','B','C' , ' D']".replace('\'','"')))
['A', 'B', 'C', ' D']
['A', 'B', 'C', ' D']

This should work:

/^((?!PART).)*$/

If you only wanted to exclude it from the beginning of the line (I know you don't, but just FYI), you could use this:

/^(?!PART)/

Edit (by request): Why this pattern works

The (?!...) syntax is a negative lookahead, which I've always found tough to explain. Basically, it means "whatever follows this point must not match the regular expression /PART/." The site I've linked explains this far better than I can, but I'll try to break this down:

^         #Start matching from the beginning of the string.    
(?!PART)  #This position must not be followed by the string "PART".
.         #Matches any character except line breaks (it will include those in single-line mode).
$         #Match all the way until the end of the string.

The ((?!xxx).)* idiom is probably hardest to understand. As we saw, (?!PART) looks at the string ahead and says that whatever comes next can't match the subpattern /PART/. So what we're doing with ((?!xxx).)* is going through the string letter by letter and applying the rule to all of them. Each character can be anything, but if you take that character and the next few characters after it, you'd better not get the word PART.

The ^ and $ anchors are there to demand that the rule be applied to the entire string, from beginning to end. Without those anchors, any piece of the string that didn't begin with PART would be a match. Even PART itself would have matches in it, because (for example) the letter A isn't followed by the exact string PART.

Since we do have ^ and $, if PART were anywhere in the string, one of the characters would match (?=PART). and the overall match would fail. Hope that's clear enough to be helpful.

You can initialize it just like any list:

public List<ContactNumber> ContactNumbers { get; set; }

public Human(int id)
{
    Id = id;
    ContactNumbers = new List<ContactNumber>();
}

public Human(int id, string address, string name) :this(id)
{
    Address = address;
    Name = name;
    // no need to initialize the list here since you're
    // already calling the single parameter constructor
}       

However, I would even go a step further and make the setter private since you often don't need to set the list, but just access/modify its contents:

public List<ContactNumber> ContactNumbers { get; private set; }

You can manually set xticks (and yticks) using pyplot.xticks:

import matplotlib.pyplot as plt
import numpy as np

x = np.array([0,1,2,3])
y = np.array([20,21,22,23])
my_xticks = ['John','Arnold','Mavis','Matt']
plt.xticks(x, my_xticks)
plt.plot(x, y)
plt.show()

Try this

$("#mydiv div.myclass")

I understand the original poster was looking for a simple solution, but unfortunately there really is no simple solution.

Nevertheless, I've recently created an open-source freeware clipping library (written in Delphi, C++ and C#) which clips all kinds of polygons (including self-intersecting ones). This library is pretty simple to use: http://sourceforge.net/projects/polyclipping/ .

I received the same error after installing android studio and trying to run hello world. I think you need to use the SDK Manager inside Android Studio to install some things first.

Open up Android Studio, and click on the SDK Manager in the toolbar.

Now install the SDK tools you need.

• Tools -> Android SDK Tools
• Tools -> Android SDK Platform-tools
• Tools -> Android SDK Build-tools (highest version)

For each Android release you are targeting, hit the appropriate Android X.X folder and select (at a minimum):

• SDK Platform
• A system image for the emulator, such as ARM EABI v7a System Image

The SDK Manager will run (this can take a while) and download and install the various SDKs.

Inside Android Studio, File->Project Structure will show you where your Android sdks are installed. As you can see mine is c:\users\Joe\AppData\Local\Android\sdk1.

If I navigate to C:\Users\Joe\AppData\Local\Android\sdk1\sources you can see the various Android SDKs installed there...

You need to use == or === for comparison. = assigns a new value.

Besides that, using == is pointless when dealing with booleans only. Just use if(foo) instead of if(foo == true).

I created an arrayList from it and I somehow can't find a way to store this information into a JTable.

The DefaultTableModel doesn't support displaying custom Objects stored in an ArrayList. You need to create a custom TableModel.

You can check out the Bean Table Model. It is a reusable class that will use reflection to find all the data in your FootballClub class and display in a JTable.

Or, you can extend the Row Table Model found in the above link to make is easier to create your own custom TableModel by implementing a few methods. The JButtomTableModel.java source code give a complete example of how you can do this.

The simplest way is to set the background-size CSS property to cover:

.jumbotron {
  background-image: url("../img/jumbotron_bg.jpg");
  background-size: cover;
}

I know it is a bit late to answer this question, but it is the first entry in google, so I think it is worth to answer it.

The problem is not a coding problem, it is an architecture problem.

You have created an interface class Event: public Item to define the methods which all events should implement. Then you have defined two types of events which inherits from class Event: public Item; Arrival and Landing and then, you have added a method Landing* createNewLanding(Arrival* arrival); from the landing functionality in the class Event: public Item interface. You should move this method to the class Landing: public Event class because it only has sense for a landing. class Landing: public Event and class Arrival: public Event class should know class Event: public Item but event should not know class Landing: public Event nor class Arrival: public Event.

I hope this helps, regards, Alberto

You have it, that's all. But so, basically, what's the point of unions?

You can put in the same location content of different types. You have to know the type of what you have stored in the union (so often you put it in a struct with a type tag...).

Why is this important? Not really for space gains. Yes, you can gain some bits or do some padding, but that's not the main point anymore.

It's for type safety, it enables you to do some kind of 'dynamic typing': the compiler knows that your content may have different meanings and the precise meaning of how your interpret it is up to you at run-time. If you have a pointer that can point to different types, you MUST use a union, otherwise you code may be incorrect due to aliasing problems (the compiler says to itself "oh, only this pointer can point to this type, so I can optimize out those accesses...", and bad things can happen).

If the strings are different (ie: [foo] & [/foo]), take a look at this post from Justin Cook. I copy his code below:

function get_string_between($string, $start, $end){
    $string = ' ' . $string;
    $ini = strpos($string, $start);
    if ($ini == 0) return '';
    $ini += strlen($start);
    $len = strpos($string, $end, $ini) - $ini;
    return substr($string, $ini, $len);
}

$fullstring = 'this is my [tag]dog[/tag]';
$parsed = get_string_between($fullstring, '[tag]', '[/tag]');

echo $parsed; // (result = dog)

Try it:

$table->integer('user_id')->unsigned()->nullable();

You can try this:

 Map<String,String> map = new HashMap<>();
 Map.Entry<String,String> entry = map.entrySet().iterator().next();
 String key = entry.getKey();
 String value = entry.getValue();

Keep in mind, HashMap does not guarantee the insertion order. Use a LinkedHashMap to keep the order intact.

Eg:

 Map<String,String> map = new LinkedHashMap<>();
 map.put("Active","33");
 map.put("Renewals Completed","3");
 map.put("Application","15");
 Map.Entry<String,String> entry = map.entrySet().iterator().next();
 String key= entry.getKey();
 String value=entry.getValue();
 System.out.println(key);
 System.out.println(value);

Output:

 Active
 33

In addition to the accepted answer you can use this if you want to group by multiple columns:

<ul ng-repeat="(key, value) in players | groupBy: '[team,name]'">

Why would you want to put a submit button inside an anchor? You are either trying to submit a form or go to a different page. Which one is it?

Either submit the form:

<input type="submit" class="button_active" value="1" />

Or go to another page:

<input type="button" class="button_active" onclick="location.href='1.html';" />

Following the useful comments, I've completely rebuilt the date formatter. Usage is supposed to:

• Be short (one liner)
• Represent disposable objects (time zone, format) as Strings
• Support useful, sortable ISO formats and the legacy format from the box

If you consider this code useful, I may publish the source and a JAR in github.

Usage

// The problem - not UTC
Date.toString()                      
"Tue Jul 03 14:54:24 IDT 2012"

// ISO format, now
PrettyDate.now()        
"2012-07-03T11:54:24.256 UTC"

// ISO format, specific date
PrettyDate.toString(new Date())         
"2012-07-03T11:54:24.256 UTC"

// Legacy format, specific date
PrettyDate.toLegacyString(new Date())   
"Tue Jul 03 11:54:24 UTC 2012"

// ISO, specific date and time zone
PrettyDate.toString(moonLandingDate, "yyyy-MM-dd hh:mm:ss zzz", "CST") 
"1969-07-20 03:17:40 CDT"

// Specific format and date
PrettyDate.toString(moonLandingDate, "yyyy-MM-dd")
"1969-07-20"

// ISO, specific date
PrettyDate.toString(moonLandingDate)
"1969-07-20T20:17:40.234 UTC"

// Legacy, specific date
PrettyDate.toLegacyString(moonLandingDate)
"Wed Jul 20 08:17:40 UTC 1969"

     */
    public static String toString(final Date date, final String format, final String timezone) {
        final TimeZone tz = TimeZone.getTimeZone(timezone);
        final SimpleDateFormat formatter = new SimpleDateFormat(format);
        formatter.setTimeZone(tz);
        return formatter.format(date);
    }
}

I liked @rich.kelly's answer, but I wanted to use the same nomenclature as classList.add() (comma seperated strings), so a slight deviation.

DOMTokenList.prototype.addMany = DOMTokenList.prototype.addMany || function() {
  for (var i = 0; i < arguments.length; i++) {
    this.add(arguments[i]);
  }
}
DOMTokenList.prototype.removeMany = DOMTokenList.prototype.removeMany || function() {
  for (var i = 0; i < arguments.length; i++) {
    this.remove(arguments[i]);
  }
}

So you can then use:

document.body.classList.addMany('class-one','class-two','class-three');

I need to test all browsers, but this worked for Chrome.
Should we be checking for something more specific than the existence of DOMTokenList.prototype.addMany? What exactly causes classList.add() to fail in IE11?

You can write the function this way also Which helps to build your code one time just to add class name or ID at the end

function equalHeight(group) {
               tallest = 0;
               group.each(function() {
                  thisHeight = jQuery(this).height();
                  if(thisHeight > tallest) {
                     tallest = thisHeight;
                  }
               });
               group.height(tallest);
            }
            equalHeight(jQuery("Add your class"));

There must be more to a Python dictionary than a table lookup on hash(). By brute experimentation I found this hash collision:

>>> hash(1.1)
2040142438
>>> hash(4504.1)
2040142438

Yet it doesn't break the dictionary:

>>> d = { 1.1: 'a', 4504.1: 'b' }
>>> d[1.1]
'a'
>>> d[4504.1]
'b'

Sanity check:

>>> for k,v in d.items(): print(hash(k))
2040142438
2040142438

Possibly there's another lookup level beyond hash() that avoids collisions between dictionary keys. Or maybe dict() uses a different hash.

(By the way, this in Python 2.7.10. Same story in Python 3.4.3 and 3.5.0 with a collision at hash(1.1) == hash(214748749.8).)

joaquin's answer works, but has the side effect of removing ticks from the left side of the axes. To fix this, follow up tick_right() with a call to set_ticks_position('both'). A revised example:

from matplotlib import pyplot as plt

f = plt.figure()
ax = f.add_subplot(111)
ax.yaxis.tick_right()
ax.yaxis.set_ticks_position('both')
plt.plot([2,3,4,5])
plt.show()

The result is a plot with ticks on both sides, but tick labels on the right.

I use PHP as my serverside language, so the example i will write in it - but i'm sure there is a method in your server side as well.

Just have your serverside language add it from a variable. w/ php something like that would go as follows.

Do note, that this will only work if the script is loaded with the page load. If you want to load it dynamically, this solution will not help you.

PHP

HTML

<head>
    <script type="text/javascript"> <?php echo $decodedstring ?> </script>
</head>

In Summary: Decode with serverside and put it in your HTML using the server language.

I was using Postman and I was doing the same mistake.. passing the value as json object instead of string

{
    "value": "test"
}

Clearly the above one is wrong when the api parameter is of type string.

So, just pass the string in double quotes in the api body:

"test"

JavaScript code using ng-controller:

$scope.checkkey = function (event) {
  alert(event.keyCode);  //this will show the ASCII value of the key pressed

}

In HTML:

<input type="text" ng-keypress="checkkey($event)" />

You can now place your checks and other conditions using the keyCode method.

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

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

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

<p style="margin-left:5em;">Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet. Phasellus tempor nisi eget tellus venenatis tempus. Aliquam dapibus porttitor convallis. Praesent pretium luctus orci, quis ullamcorper lacus lacinia a. Integer eget molestie purus. Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra, per inceptos himenaeos. </p>

That'll do it, there's a few improvements obviously, but that's the basics. And I use 'em' as the measurement, you may want to use other units, like 'px'.

EDIT: What they're describing above is a way of associating groups of styles, or classes, with elements on a web page. You can implement that in a few ways, here's one which may suit you:

In your HTML page, containing the <p> tagged content from your DB add in a new 'style' node and wrap the styles you want to declare in a class like so:

<head>
  <style type="text/css">
    p { margin-left:5em; /* Or another measurement unit, like px */ }
  </style>
</head>
<body>
  <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
</body>

So above, all <p> elements in your document will have that style rule applied. Perhaps you are pumping your paragraph content into a container of some sort? Try this:

<head>
  <style type="text/css">
    .container p { margin-left:5em; /* Or another measurement unit, like px */ }
  </style>
</head>
<body>
  <div class="container">
    <p>Lorem ipsum dolor sit amet, consectetur adipiscing elit. Ut lacinia vestibulum quam sit amet aliquet.</p>
  </div>
  <p>Vestibulum porta mollis tempus. Class aptent taciti sociosqu ad litora torquent per conubia nostra.</p>
</body>

In the example above, only the <p> element inside the div, whose class name is 'container', will have the styles applied - and not the <p> element outside the container.

In addition to the above, you can collect your styles together and remove the style element from the <head> tag, replacing it with a <link> tag, which points to an external CSS file. This external file is where you'd now put your <p> tag styles. This concept is known as 'seperating content from style' and is considered good practice, and is also an extendible way to create styles, and can help with low maintenance.

Use return operator:

function FUNCT {
  if [ blah is false ]; then
    return 1 # or return 0, or even you can omit the argument.
  else
    keep running the function
  fi
}

Another way of escaping the apostrophe is to write a string literal:

insert into Person (First, Last) values (q'[Joe]', q'[O'Brien]')

This is a better approach, because:

1. Imagine you have an Excel list with 1000's of names you want to upload to your database. You may simply create a formula to generate 1000's of INSERT statements with your cell contents instead of looking manually for apostrophes.

2. It works for other escape characters too. For example loading a Regex pattern value, i.e. ^( *)(P|N)?( *)|( *)((<|>)\d\d?)?( *)|( )(((?i)(in|not in)(?-i) ?(('[^']+')(, ?'[^']+'))))?( *)$ into a table.

[request setValue:@"application/zip" forHTTPHeaderField:@"Content-Type"];

An example based on Chuck's answer:

myIntToStr :: Int -> String
myIntToStr x
    | x < 3     = show x ++ " is less than three"
    | otherwise = "normal"

Note that without the show the third line will not compile.

The problem happens when a floated element is within a container box, that element does not automatically force the container’s height adjust to the floated element. When an element is floated, its parent no longer contains it because the float is removed from the flow. You can use 2 methods to fix it:

• { clear: both; }
• clearfix

Once you understand what is happening, use the method below to “clearfix” it.

.clearfix:after {
    content: ".";
    display: block;
    clear: both;
    visibility: hidden;
    line-height: 0;
    height: 0;
}

.clearfix {
    display: inline-block;
}

html[xmlns] .clearfix {
    display: block;
}

* html .clearfix {
    height: 1%;
}

I had the same problem with spring, commons-dbcp and oracle 10g. Using this URL I got the 'no suitable driver' error: jdbc:oracle:[email protected]:1521:kinangop

The above URL is missing a full colon just before the @. After correcting that, the error disappeared.

The accepted answer helped me on the right path to figuring out how to solve this problem for the screwed up project I had to start working with. However, I had to deal with a very large number of bad include headers. With the verbose debug output, removing one caused the IDE to freeze for 30 seconds while outputting debug spew, which made the process go very slowly.

I got impatient and wrote a quick-and-dirty Python script to check the (Visual Studio 2010) project files for me and output all the missing files at once, along with the filters they're located in. You can find it as a Gist here: https://gist.github.com/antiuniverse/3825678 (or this fork that supports relative paths)

Example:

D:\...> check_inc.py sdk/src/game/client/swarm_sdk_client.vcxproj

if not os.path.isabs(projectFileName):
   projectFileName = os.path.join(os.getcwd(), projectFileName)

filterTree = ET.parse(projectFileName+".filters")
filterRoot = filterTree.getroot()
filterDict = dict()
missingDict = dict()

for inc in filterRoot.iter(ns+'ClInclude'):
    incFileRel = inc.get('Include')
    incFilter = inc.find(ns+'Filter')
    if incFileRel != None and incFilter != None:
        filterDict[incFileRel] = incFilter.text
        if incFilter.text not in missingDict:
            missingDict[incFilter.text] = []

projTree = ET.parse(projectFileName)
projRoot = projTree.getroot()

    incFileRel = inc.get('Include')
    if incFileRel != None:
        incFile = os.path.abspath(os.path.join(os.path.dirname(projectFileName), incFileRel))
        if not os.path.exists(incFile):
            missingDict[filterDict[incFileRel]].append(incFileRel)

for (missingGroup, missingList) in missingDict.items():

        for missing in missingList:
            print("  " + os.path.basename(missing) + "   (" + missing + ")")

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

Modernized and slightly modified version of the extension methods for ToStream:

public static Stream ToStream(this string value) => ToStream(value, Encoding.UTF8);

public static Stream ToStream(this string value, Encoding encoding) 
                          => new MemoryStream(encoding.GetBytes(value ?? string.Empty));

Modification as suggested in @Palec's comment of @Shaun Bowe answer.

You can get good Time Series graphs in Excel, the way you want, but you have to work with a few quirks.

1. Be sure to select "Scatter Graph" (with a line option). This is needed if you have non-uniform time stamps, and will scale the X-axis accordingly.

2. In your data, you need to add a column with the mid-point. Here's what I did with your sample data. (This trick ensures that the data gets plotted at the mid-point, like you desire.)

3. You can format the x-axis options with this menu. (Chart->Design->Layout)

4. Select "Axes" and go to Primary Horizontal Axis, and then select "More Primary Horizontal Axis Options"

5. Set up the options you wish. (Fix the starting and ending points.)

6. And you will get a graph such as the one below.

You can then tweak many of the options, label the axes better etc, but this should get you started.

Hope this helps you move forward.

The culprit in my case was returning a No Content response but defining a response body at the same time. May this answer remind me and maybe others not to return a NoContent response with a body ever again.

This behavior is consistent with 10.2.5 204 No Content of the HTTP specification which says:

The 204 response MUST NOT include a message-body, and thus is always terminated by the first empty line after the header fields.

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

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

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

You may use the contain selector:

[name*=”value”]: selects elements that have the specified attribute with a value containing a given substring.

$( document ).on( "keyup", "input[name*='pages_title']", function() {
     alert($(this).val());
});

Alternatively you could use my service, https://astroip.co, it is a new Geolocation API:

$.get("https://api.astroip.co/?api_key=1725e47c-1486-4369-aaff-463cc9764026", function(response) {
    console.log(response.geo.city, response.geo.country);
});

AstroIP provides geolocation data together with security datapoints like proxy, TOR nodes and crawlers detection. The API also returns currency, timezones, ASN and company data.

It is a pretty new api with an average response time of 40ms from multiple regions around the world, which positions it in the handful list of super fast Geolocation APIs available.

Big free plan of up to 30,000 requests per month for free is available.

Check out mk-parallel-dump which is part of the ever-useful maatkit suite of tools. This can dump comma-separated files with the --csv option.

This can do your whole db without specifying individual tables, and you can specify groups of tables in a backupset table.

Note that it also dumps table definitions, views and triggers into separate files. In addition providing a complete backup in a more universally accessible form, it also immediately restorable with mk-parallel-restore

Option 2 is correct: The nested <ul> is a child of the <li> it belongs in.

If you validate, option 1 comes up as an error in html 5 -- credit: user3272456

Correct: <ul> as child of <li>

The proper way to make HTML nested list is with the nested <ul> as a child of the <li> to which it belongs. The nested list should be inside of the <li> element of the list in which it is nested.

<ul>
    <li>Parent/Item
        <ul>
            <li>Child/Subitem
            </li>
        </ul>
    </li>
</ul>

W3C Standard for Nesting Lists

A list item can contain another entire list — this is known as "nesting" a list. It is useful for things like tables of contents, such as the one at the start of this article:

1. Chapter One
   1. Section One
   2. Section Two
   3. Section Three
2. Chapter Two
3. Chapter Three

The key to nesting lists is to remember that the nested list should relate to one specific list item. To reflect that in the code, the nested list is contained inside that list item. The code for the list above looks something like this:

<ol>
  <li>Chapter One
    <ol>
      <li>Section One</li>
      <li>Section Two </li>
      <li>Section Three </li>
    </ol>
  </li>
  <li>Chapter Two</li>
  <li>Chapter Three  </li>
</ol>

Note how the nested list starts after the <li> and the text of the containing list item (“Chapter One”); then ends before the </li> of the containing list item. Nested lists often form the basis for website navigation menus, as they are a good way to define the hierarchical structure of the website.

Theoretically you can nest as many lists as you like, although in practice it can become confusing to nest lists too deeply. For very large lists, you may be better off splitting the content up into several lists with headings instead, or even splitting it up into separate pages.

How about this: catch a very general exception, make sure it makes it out of the catch block, then assert that the class of the exception is what you expect it to be. This assert will fail if a) the exception is of the wrong type (eg. if you got a Null Pointer instead) and b) the exception wasn't ever thrown.

public void testFooThrowsIndexOutOfBoundsException() {
  Throwable e = null;

  try {
    foo.doStuff();
  } catch (Throwable ex) {
    e = ex;
  }

  assertTrue(e instanceof IndexOutOfBoundsException);
}

You need to do something like this:

// instantiate XmlDocument and load XML from file
XmlDocument doc = new XmlDocument();
doc.Load(@"D:\test.xml");

// get a list of nodes - in this case, I'm selecting all <AID> nodes under
// the <GroupAIDs> node - change to suit your needs
XmlNodeList aNodes = doc.SelectNodes("/Equipment/DataCollections/GroupAIDs/AID");

// loop through all AID nodes
foreach (XmlNode aNode in aNodes)
{
   // grab the "id" attribute
   XmlAttribute idAttribute = aNode.Attributes["id"];

   // check if that attribute even exists...
   if (idAttribute != null)
   {
      // if yes - read its current value
      string currentValue = idAttribute.Value;

      // here, you can now decide what to do - for demo purposes,
      // I just set the ID value to a fixed value if it was empty before
      if (string.IsNullOrEmpty(currentValue))
      {
         idAttribute.Value = "515";
      }
   }
}

// save the XmlDocument back to disk
doc.Save(@"D:\test2.xml");

It is as easy as specifying a padding bottom the same size as the width in percent. So if you have a width of 50%, just use this example below

id or class{
    width: 50%;
    padding-bottom: 50%;
}

This can happen on foreachs when using:

foreach( $array as $key = $value )

instead of

foreach( $array as $key => $value )

The @ disables echo for that one command. Without it, the echo start eclipse.exe line would print both the intended start eclipse.exe and the echo start eclipse.exe line.

The echo off turns off the by-default command echoing.

So @echo off silently turns off command echoing, and only output the batch author intended to be written is actually written.

For the sake of completeness, here's another possible solution:

SELECT sensorID,timestamp,sensorField1,sensorField2 
FROM sensorTable s1
WHERE timestamp = (SELECT MAX(timestamp) FROM sensorTable s2 WHERE s1.sensorID = s2.sensorID)
ORDER BY sensorID, timestamp;

Pretty self-explaining I think, but here's more info if you wish, as well as other examples. It's from the MySQL manual, but above query works with every RDBMS (implementing the sql'92 standard).

In that scenario use map, you don't need a new Observable for it.

you should use Exceptions.propagate, which is a wrapper so you can send those checked exceptions to the rx mechanism

Observable<String> obs = Observable.from(jsonFile).map(new Func1<File, String>() { 
    @Override public String call(File file) {
        try { 
            return new Gson().toJson(new FileReader(file), Object.class);
        } catch (FileNotFoundException e) {
            throw Exceptions.propagate(t); /will propagate it as error
        } 
    } 
});

You then should handle this error in the subscriber

obs.subscribe(new Subscriber<String>() {
    @Override 
    public void onNext(String s) { //valid result }

    @Override 
    public void onCompleted() { } 

    @Override 
    public void onError(Throwable e) { //e might be the FileNotFoundException you got }
};); 

There is an excellent post for it: http://blog.danlew.net/2015/12/08/error-handling-in-rxjava/

In python 3, a way of doing this would be

    layout.setLayoutParams(labelLayoutParams);


   // If you want to add some controls in this Relative Layout
    labelLayoutParams = new RelativeLayout.LayoutParams(
            LayoutParams.WRAP_CONTENT, LayoutParams.WRAP_CONTENT);
    labelLayoutParams.addRule(RelativeLayout.CENTER_IN_PARENT);


    ImageView mImage = new ImageView(this);
    mImage.setBackgroundResource(R.drawable.popupnew_bg);        
    layout.addView(mImage,labelLayoutParams);

    setContentView(layout);

Make videoView a member variable of your activity class instead of keeping it as local to the onCreate function:

VideoView videoView;

@Override
public void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.main);
    videoView = (VideoView)findViewById(R.id.VideoView);        
    videoView.setVideoPath("/sdcard/blonde_secretary.3gp");
    videoView.start();  
}

While it is common for new programmer to make this mistake of performing integer division when they actually meant to use floating point division, in actual practice integer division is a very common operation. If you are assuming that people rarely use it, and that every time you do division you'll always need to remember to cast to floating points, you are mistaken.

First off, integer division is quite a bit faster, so if you only need a whole number result, one would want to use the more efficient algorithm.

Secondly, there are a number of algorithms that use integer division, and if the result of division was always a floating point number you would be forced to round the result every time. One example off of the top of my head is changing the base of a number. Calculating each digit involves the integer division of a number along with the remainder, rather than the floating point division of the number.

Because of these (and other related) reasons, integer division results in an integer. If you want to get the floating point division of two integers you'll just need to remember to cast one to a double/float/decimal.

I have been working on a solution to this issue as none of the above answers really helped me. I am working with the jquery week calendar and needed my dates to have time zone information on the server and locally on the page. After quite a bit of digging around, I figured out a solution that may help others.

I am using asp.net 3.5, vs 2008, asp.net MVC 2, and jquery week calendar,

First, I am using a library written by Steven Levithan that helps with dealing with dates on the client side, Steven Levithan's date library. The isoUtcDateTime format is perfect for what I needed. In my jquery AJAX call I use the format function provided with the library with the isoUtcDateTime format and when the ajax call hits my action method, the datetime Kind is set to local and reflects the server time.

When I send dates to my page via AJAX, I send them as text strings by formatting the dates using "ddd, dd MMM yyyy HH':'mm':'ss 'GMT'zzzz". This format is easily converted client side using

var myDate = new Date(myReceivedDate);

Here is my complete solution minus Steve Levithan's source, which you can download:

Controller:

public class HomeController : Controller
{
    public const string DATE_FORMAT = "ddd, dd MMM yyyy HH':'mm':'ss 'GMT'zzzz";

    public ActionResult Index()
    {
        ViewData["Message"] = "Welcome to ASP.NET MVC!";

        return View();
    }

    public ActionResult About()
    {
        return View();
    }


    public JsonResult GetData()
    {
        DateTime myDate = DateTime.Now.ToLocalTime();

        return new JsonResult { Data = new { myDate = myDate.ToString(DATE_FORMAT) } };
    }

    public JsonResult ReceiveData(DateTime myDate)
    {
        return new JsonResult { Data = new { myDate = myDate.ToString(DATE_FORMAT) } };
    }
}

Javascript:

<script type="text/javascript">

function getData() {
    $.ajax({
        url: "/Home/GetData",
        type: "POST",
        cache: "false",
        dataType: "json",
        success: function(data) {
            alert(data.myDate);
            var newDate = cleanDate(data.myDate);
            alert(newDate);
            sendData(newDate);
        }
    });
} 

function cleanDate(d) {
    if (typeof d == 'string') {
        return new Date(d) || Date.parse(d) || new Date(parseInt(d));
    }
    if (typeof d == 'number') {
        return new Date(d);
    }
    return d;
}

function sendData(newDate) {
    $.ajax({
        url: "/Home/ReceiveData",
        type: "POST",
        cache: "false",
        dataType: "json",
        data:
        {
            myDate: newDate.format("isoUtcDateTime")
        },
        success: function(data) {
            alert(data.myDate);
            var newDate = cleanDate(data.myDate);
            alert(newDate);
        }
    });
}

// bind myButton click event to call getData
$(document).ready(function() {
    $('input#myButton').bind('click', getData);
});
</script>

I hope this quick example helps out others in the same situation I was in. At this time it seems to work very well with the Microsoft JSON Serialization and keeps my dates correct across timezones.

As far as I'm aware this is the only answer here that works correctly with spaces:

space:= 
space+=

CURRENT_PATH := $(subst $(lastword $(notdir $(MAKEFILE_LIST))),,$(subst $(space),\$(space),$(shell realpath '$(strip $(MAKEFILE_LIST))')))

It essentially works by escaping space characters by substituting ' ' for '\ ' which allows Make to parse it correctly, and then it removes the filename of the makefile in MAKEFILE_LIST by doing another substitution so you're left with the directory that makefile is in. Not exactly the most compact thing in the world but it does work.

You'll end up with something like this where all the spaces are escaped:

$(info CURRENT_PATH = $(CURRENT_PATH))

CURRENT_PATH = /mnt/c/Users/foobar/gDrive/P\ roje\ cts/we\ b/sitecompiler/

1. Normal Class: A Java class

2. Java Beans:

   • All properties private (use getters/setters)
   • A public no-argument constructor
   • Implements Serializable.

3. Pojo: Plain Old Java Object is a Java object not bound by any restriction other than those forced by the Java Language Specification. I.e., a POJO should not have to

   • Extend prespecified classes
   • Implement prespecified interface
   • Contain prespecified annotations

java.time

The java.time framework built into Java 8 and later supplants both the old date-time classes bundled with the earliest versions of Java and the Joda-Time library. The java.time classes have been back-ported to Java 6 & 7 and to Android.

The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds.

Instant instant = Instant.now();

Apply an offset-from-UTC (a number of hours and possible minutes and seconds) to get an OffsetDateTime.

ZoneOffset offset = ZoneOffset.of( "-04:00" );
OffsetDateTime odt = OffsetDateTime.ofInstant( instant , offset );

Better yet is applying a full time zone which is an offset plus a set of rules for handling anomalies such as Daylight Saving Time (DST).

ZoneId zoneId = ZoneId.of( "America/Montreal" );
ZonedDateTime zdt = ZonedDateTime.ofInstant( instant , zoneId );

Database

Hopefully the JDBC drivers will be updated to work directly with the java.time classes. Until then we must use the java.sql classes to move date-time values to/from the database. But limit your use of the java.sql classes to the chore of database transit. Do not use them for business logic. As part of the old date-time classes they are poorly designed, confusing, and troublesome.

Use new methods added to the old classes to convert to/from java.time. Look for to… and valueOf methods.

Use the java.sql.Timestamp class for date-time values.

java.sql.Timestamp ts = java.sql.Timestamp.valueOf( instant );

And going the other direction…

Instant instant = ts.toInstant();

For date-time data you virtually always want the TIMESTAMP WITH TIME ZONE data type rather than WITHOUT when designing your table columns in your database.

Only one thing you have to do. Type this in in your Command Prompt: ng serve --port 4021 [or any other port you want to assign eg: 5050, 5051 etc ]. No need to do changes in files.

I spent ages trying to figure this out but it is simple! You can use length(·). length(mylist) will tell you the number of objects mylist contains.

... and just realised someone had already answered this- sorry!

Use .toString instead like below:

String myString = myIntegerObject.toString();

I find it a lot cleaner to pass an @INPUT variable if you have access to the child component code:

The idea is that the parent tells the child what its state of appearance should be, and the child decides how to display the state. It's a nice architecture

SCSS Way:

.active {
  ::ng-deep md-list-item {
    background-color: #eee;
  }
}

Better way: - use selected variable:

<md-list>
    <a
            *ngFor="let convo of conversations"
            routerLink="/conversations/{{convo.id}}/messages"
            #rla="routerLinkActive"
            routerLinkActive="active">
        <app-conversation
                [selected]="rla.isActive"
                [convo]="convo"></app-conversation>
    </a>
</md-list>

From the "Text Contains" dropdown menu select "Custom formula is:", and write: "=countif(A:A, A1) > 1" (without the quotes)

I did exactly as zolley proposed, but there should be done small correction: use "Custom formula is" instead of "Text Contains". And then conditional rendering will work.

Can you change the ownership of the file then change it back after using cat >> to append?

sudo chown youruser /etc/hosts  
sudo cat /downloaded/hostsadditions >> /etc/hosts  
sudo chown root /etc/hosts  

Something like this work for you?

I still remember the first weeks of my programming courses and I totally understand how you feel. Here is the code that solves your problem. In order to learn from this answer, try to run it adding several 'print' in the loop, so you can see the progress of the variables.

import java.util.*;
import java.lang.*;

public class foo
{

   public static void main(String[] args)
   { 
      double[] alpha = new double[50];
      int count = 0;

      for (int i=0; i<50; i++)
      {
          // System.out.print("variable i = " + i + "\n");
          if (i < 25)
          {
                alpha[i] = i*i;
          }
          else {
                alpha[i] = 3*i;
          }

          if (count < 10)
          {
            System.out.print(alpha[i]+ " "); 
          }  
          else {
            System.out.print("\n"); 
            System.out.print(alpha[i]+ " "); 
            count = 0;
          }

          count++;
      }

      System.out.print("\n"); 

    }
}

You have to specify any one of the above phase to resolve the above error. In most of the situations, this would have occurred due to running the build from the eclipse environment.

instead of mvn clean package or mvn package you can try only package its work fine for me

If you are experiencing this error over a https connection and it's happening instantly it could be a problem setting up the SSL connection.

For me it was this issue https://github.com/nodejs/node/issues/9845 but for you it could be something else. If it is a problem with the ssl then you should be able to reproduce it with the nodejs tls/ssl package just trying to connect to the domain

Just another exception to the already posted list. On 32-bit platforms, pointers can take 6, not 4, bytes:

#include <stdio.h>
#include <stdlib.h>

int main() {
    char far* ptr; // note that this is a far pointer
    printf( "%d\n", sizeof( ptr));
    return EXIT_SUCCESS;
}

If you compile this program with Open Watcom and run it, you'll get 6, because far pointers that it supports consist of 32-bit offset and 16-bit segment values

Threadlocal provides a very easy way to achieve objects reusability with zero cost.

I had a situation where multiple threads were creating an image of mutable cache, on each update notification.

I used a Threadlocal on each thread, and then each thread would just need to reset old image and then update it again from the cache on each update notification.

Usual reusable objects from object pools have thread safety cost associated with them, while this approach has none.

I know this is a very old post but this might help. This is a very small workaround by me

$('#myModal').trigger('click');

Thats it, This should solve the issue

Note that this behaves the same on IIS 6 and 7.x, and .NET 2, 3, and 4.x.

Also note that when app_offline.htm is present, IIS will return this http status code:

HTTP/1.1 503 Service Unavailable

This is all by design. This allows your load balancer (or whatever) to see that the server is off line.

Use get_the_category() function.

$post_categories = wp_get_post_categories( 4 );
$categories = get_the_category($post_categories[0]);
var_dump($categories);

Converting anything to a string should either 1) allocate the resultant string or 2) pass in a char * destination and size. Sample code below:

Both work for all int including INT_MIN. They provide a consistent output unlike snprintf() which depends on the current locale.

Method 1: Returns NULL on out-of-memory.

#define INT_DECIMAL_STRING_SIZE(int_type) ((CHAR_BIT*sizeof(int_type)-1)*10/33+3)

char *int_to_string_alloc(int x) {
  int i = x;
  char buf[INT_DECIMAL_STRING_SIZE(int)];
  char *p = &buf[sizeof buf - 1];
  *p = '\0';
  if (i >= 0) {
    i = -i;
  }
  do {
    p--;
    *p = (char) ('0' - i % 10);
    i /= 10;
  } while (i);
  if (x < 0) {
    p--;
    *p = '-';
  }
  size_t len = (size_t) (&buf[sizeof buf] - p);
  char *s = malloc(len);
  if (s) {
    memcpy(s, p, len);
  }
  return s;
}

Method 2: It returns NULL if the buffer was too small.

static char *int_to_string_helper(char *dest, size_t n, int x) {
  if (n == 0) {
    return NULL;
  }
  if (x <= -10) {
    dest = int_to_string_helper(dest, n - 1, x / 10);
    if (dest == NULL) return NULL;
  }
  *dest = (char) ('0' - x % 10);
  return dest + 1;
}

char *int_to_string(char *dest, size_t n, int x) {
  char *p = dest;
  if (n == 0) {
    return NULL;
  }
  n--;
  if (x < 0) {
    if (n == 0) return NULL;
    n--;
    *p++ = '-';
  } else {
    x = -x;
  }
  p = int_to_string_helper(p, n, x);
  if (p == NULL) return NULL;
  *p = 0;
  return dest;
}

[Edit] as request by @Alter Mann

(CHAR_BIT*sizeof(int_type)-1)*10/33+3 is at least the maximum number of char needed to encode the some signed integer type as a string consisting of an optional negative sign, digits, and a null character..

The number of non-sign bits in a signed integer is no more than CHAR_BIT*sizeof(int_type)-1. A base-10 representation of a n-bit binary number takes up to n*log10(2) + 1 digits. 10/33 is slightly more than log10(2). +1 for the sign char and +1 for the null character. Other fractions could be used like 28/93.

Method 3: If one wants to live on the edge and buffer overflow is not a concern, a simple C99 or later solution follows which handles all int.

#include <limits.h>
#include <stdio.h>

static char *itoa_simple_helper(char *dest, int i) {
  if (i <= -10) {
    dest = itoa_simple_helper(dest, i/10);
  }
  *dest++ = '0' - i%10;
  return dest;
}

char *itoa_simple(char *dest, int i) {
  char *s = dest;
  if (i < 0) {
    *s++ = '-';
  } else {
    i = -i;
  }
  *itoa_simple_helper(s, i) = '\0';
  return dest;
}

int main() {
  char s[100];
  puts(itoa_simple(s, 0));
  puts(itoa_simple(s, 1));
  puts(itoa_simple(s, -1));
  puts(itoa_simple(s, 12345));
  puts(itoa_simple(s, INT_MAX-1));
  puts(itoa_simple(s, INT_MAX));
  puts(itoa_simple(s, INT_MIN+1));
  puts(itoa_simple(s, INT_MIN));
}

Sample output

2147483646
2147483647
-2147483647
-2147483648

A slightly more efficient version of the bytes2String method is

private static final char[] hex = {'0', '1', '2', '3', '4', '5', '6', '7', '8', '9', 'a', 'b', 'c', 'd', 'e', 'f'};
private static String byteArray2Hex(byte[] bytes) {
    StringBuilder sb = new StringBuilder(bytes.length * 2);
    for (final byte b : bytes) {
        sb.append(hex[(b & 0xF0) >> 4]);
        sb.append(hex[b & 0x0F]);
    }
    return sb.toString();
}

Looking all answers I compose universal function what working on all PHP versions.

if(!function_exists('date_between')) :
    function date_between($date_start, $date_end)
    {
        if(!$date_start || !$date_end) return 0;

        if( class_exists('DateTime') )
        {
            $date_start = new DateTime( $date_start );
            $date_end   = new DateTime( $date_end );
            return $date_end->diff($date_start)->format('%a');
        }
        else
        {           
            return abs( round( ( strtotime($date_start) - strtotime($date_end) ) / 86400 ) );
        }
    }
endif;

In the general, I use 'DateTime' to find days between 2 dates. But if in the some reason, some server setup not have 'DateTime' enabled, it will use simple (but not safe) calculation with 'strtotime()'.

If I may I could give you some new code for the same task, in my code you can create a so called 'document'(not really)and it is saved, and can be opened up again. It is also stored as a string file though(not a document). Here is the code:

#include "iostream"

#include "windows.h"

#include "string"

#include "fstream"

using namespace std;

int main() {

string saveload;


cout << "---------------------------" << endl;
cout << "|enter 'text' to write your document    |" << endl;
cout << "|enter 'open file' to open the document |" << endl;
cout << "----------------------------------------" << endl;
while (true){
    getline(cin, saveload);

    if (saveload == "open file"){
        string filenamet;
        cout << "file name? " << endl;
        getline(cin, filenamet, '*');
        ifstream loadFile;

        loadFile.open(filenamet, ifstream::in);

        cout << "the text you entered was: ";

        while (loadFile.good()){

            cout << (char)loadFile.get();

            Sleep(100);
        }

        cout << "" << endl;

        loadFile.close();

    }

    if (saveload == "text") {
        string filename;
        cout << "file name: " << endl;
        getline(cin, filename,'*');
        string textToSave;
        cout << "Enter your text: " << endl;
        getline(cin, textToSave,'*');

        ofstream saveFile(filename);

        saveFile << textToSave;

        saveFile.close();

    }
}
return 0;
}

Just take this code and change it to serve your purpose. DREAM BIG,THINK BIG, DO BIG

This is another option to write a pandas dataframe directly into a matplotlib table:

import matplotlib.pyplot as plt

fig, ax = plt.subplots()

# hide axes
fig.patch.set_visible(False)
ax.axis('off')
ax.axis('tight')

ax.table(cellText=df.values, colLabels=df.columns, loc='center')

fig.tight_layout()

In the Google Maps API v2 Demo there is a MarkerDemoActivity class in which you can see how a custom Image is set to a GoogleMap.

// Uses a custom icon.
mSydney = mMap.addMarker(new MarkerOptions()
    .position(SYDNEY)
    .title("Sydney")
    .snippet("Population: 4,627,300")
    .icon(BitmapDescriptorFactory.fromResource(R.drawable.arrow)));

As this just replaces the marker with an image you might want to use a Canvas to draw more complex and fancier stuff:

Bitmap.Config conf = Bitmap.Config.ARGB_8888;
Bitmap bmp = Bitmap.createBitmap(80, 80, conf);
Canvas canvas1 = new Canvas(bmp);

// paint defines the text color, stroke width and size
Paint color = new Paint();
color.setTextSize(35);
color.setColor(Color.BLACK);

// modify canvas
canvas1.drawBitmap(BitmapFactory.decodeResource(getResources(),
    R.drawable.user_picture_image), 0,0, color);
canvas1.drawText("User Name!", 30, 40, color);

// add marker to Map
mMap.addMarker(new MarkerOptions()
    .position(USER_POSITION)
    .icon(BitmapDescriptorFactory.fromBitmap(bmp))
    // Specifies the anchor to be at a particular point in the marker image.
    .anchor(0.5f, 1));

This draws the Canvas canvas1 onto the GoogleMap mMap. The code should (mostly) speak for itself, there are many tutorials out there how to draw a Canvas. You can start by looking at the Canvas and Drawables from the Android Developer page.

Now you also want to download a picture from an URL.

URL url = new URL(user_image_url);
HttpURLConnection conn = (HttpURLConnection) url.openConnection();   
conn.setDoInput(true);   
conn.connect();     
InputStream is = conn.getInputStream();
bmImg = BitmapFactory.decodeStream(is); 

You must download the image from an background thread (you could use AsyncTask or Volley or RxJava for that).

After that you can replace the BitmapFactory.decodeResource(getResources(), R.drawable.user_picture_image) with your downloaded image bmImg.

I can't get to your google docs file at the moment but there are some issues with your code that I will try to address while answering

I changed you worksheet to play with (see above for the new Sub). This probably does not suite your needs directly, but hopefully it will demonstrate the conept behind what I think you want to do. Please keep in mind that this code does not follow all the coding best preactices I would recommend (e.g. validating the time is actually a TIME and not some random other data type).

jQuery("a[id=atag]").click( function(){

    jQuery('#form-id').submit();      

            **OR**

    jQuery(this).parents("#form-id").submit();
});

As far as I know there isn't any straight forward HTML Encode/Decode method in javascript.

However, what you can do, is to use JS to create an arbitrary element, set its inner text, then read it using innerHTML.

Let's say, with jQuery, this should work:

var helper = $('chalk & cheese').hide().appendTo('body');
var htmled = helper.html();
helper.remove();

Or something along these lines.

For Android, Volley is a good place to get started. For all platforms, you might also want to check out ktor client or http4k which are both good libraries.

However, you can also use standard Java libraries like java.net.HttpURLConnection which is part of the Java SDK:

fun sendGet() {
    val url = URL("http://www.google.com/")

    with(url.openConnection() as HttpURLConnection) {
        requestMethod = "GET"  // optional default is GET

        println("\nSent 'GET' request to URL : $url; Response Code : $responseCode")

        inputStream.bufferedReader().use {
            it.lines().forEach { line ->
                println(line)
            }
        }
    }
}

Or simpler:

URL("https://google.com").readText()

It looks like you want:

public static string GetRandomBits()

Without static, you would need an object before you can call the GetRandomBits() method. However, since the implementation of GetRandomBits() does not depend on the state of any Program object, it's best to declare it static.

As mentioned by you follow PEP 8 for the main text, and PEP 257 for docstring conventions

Along with Python Style Guides, I suggest that you refer the following:

1. Code Like a Pythonista: Idiomatic Python
2. Common mistakes and Warts
3. How not to write Python code
4. Python gotcha

Here is a pure MongoDB based solution for this problem which I just wrote for fun. It's effectively a server-side string-to-number parser which supports positive and negative numbers as well as decimals:

db.collection.aggregate({
    $addFields: {
        "moop": {
            $reduce: {
                "input": {
                    $map: { // split string into char array so we can loop over individual characters
                        "input": {
                            $range: [ 0, { $strLenCP: "$moop" } ] // using an array of all numbers from 0 to the length of the string
                        },
                        "in":{
                            $substrCP: [ "$moop", "$$this", 1 ] // return the nth character as the mapped value for the current index
                        }
                    }
                },
                "initialValue": { // initialize the parser with a 0 value
                    "n": 0, // the current number
                    "sign": 1, // used for positive/negative numbers
                    "div": null, // used for shifting on the right side of the decimal separator "."
                    "mult": 10 // used for shifting on the left side of the decimal separator "."
                }, // start with a zero

I am certainly not advertising this as the bee's knees or anything and it might have severe performance implications for larger datasets over a client based solutions but there might be cases where it comes in handy...

The above pipeline will transform the following documents:

{ "moop": "12345" } --> { "moop": 12345 }

and

{ "moop": "123.45" } --> { "moop": 123.45 }

and

{ "moop": "-123.45" } --> { "moop": -123.45 }

and

{ "moop": "2018-01-03" } --> { "moop": 20180103.0 }

I recently needed to launch a Bootstrap 5 modal without jQuery and not with a button click (eg, on page load) using Django messages. This is how I did it:

Template/HTML

<div class="modal" id="notification">
  <div class="modal-dialog modal-dialog-centered">
    <div class="modal-content">
      <div class="modal-header">
        <h5 class="modal-title">Notification!</h5>
        <button type="button" class="btn-close"
                data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div class="modal-body">
        {% for m in messages %}
          {{ m }}
        {% endfor %}
      </div>
      <div class="modal-footer justify-content-between">
        <a class="float-none btn btn-secondary" href="{% url 'some_view' %}"
           type="button">
          Link/Button A
        </a>
        <button type="button" class="btn btn-primary"
                data-bs-dismiss="modal">
          Link/Button B
        </button>
      </div>
    </div>
  </div>
</div>

JS in a file or in the template

{% block javascript %}
  {{ block.super }}
  <script>
    var test_modal = new bootstrap.Modal(
      document.getElementById('notification')
    )
    test_modal.show()
  </script>
{% endblock javascript %}

This method will work without the Django template; just use the HTML and put the JS in a file or script elements that loads after the Bootstrap JS before the end of the body element.

This answer will sum up almost all the queries about when to use List and Array:

1. The main difference between these two data types is the operations you can perform on them. For example, you can divide an array by 3 and it will divide each element of array by 3. Same can not be done with the list.

2. The list is the part of python's syntax so it doesn't need to be declared whereas you have to declare the array before using it.

3. You can store values of different data-types in a list (heterogeneous), whereas in Array you can only store values of only the same data-type (homogeneous).

4. Arrays being rich in functionalities and fast, it is widely used for arithmetic operations and for storing a large amount of data - compared to list.

5. Arrays take less memory compared to lists.

Can you test with surefire 2.6 and either configure Surefire with <testFailureIgnore>true</testFailureIgnore>.

Or on the command line:

mvn install -Dmaven.test.failure.ignore=true

As an alternative, there's a nice 3rd party library designed just for this use case. Whereby you need to generate headers based on the data being stored in the adapter. They are called Rolodex adapters and are used with ExpandableListViews. They can easily be customized to behave like a normal list with headers.

Using the OP's Event objects and knowing the headers are based on the Date associated with it...the code would look something like this:

The Activity

    //There's no need to pre-compute what the headers are. Just pass in your List of objects. 
    EventDateAdapter adapter = new EventDateAdapter(this, mEvents);
    mExpandableListView.setAdapter(adapter);

The Adapter

private class EventDateAdapter extends NFRolodexArrayAdapter<Date, Event> {

    public EventDateAdapter(Context activity, Collection<Event> items) {
        super(activity, items);
    }

    @Override
    public Date createGroupFor(Event childItem) {
        //This is how the adapter determines what the headers are and what child items belong to it
        return (Date) childItem.getDate().clone();
    }

    @Override
    public View getChildView(LayoutInflater inflater, int groupPosition, int childPosition,
                             boolean isLastChild, View convertView, ViewGroup parent) {
        //Inflate your view

        //Gets the Event data for this view
        Event event = getChild(groupPosition, childPosition);

        //Fill view with event data
    }

    @Override
    public View getGroupView(LayoutInflater inflater, int groupPosition, boolean isExpanded,
                             View convertView, ViewGroup parent) {
        //Inflate your header view

        //Gets the Date for this view
        Date date = getGroup(groupPosition);

        //Fill view with date data
    }

    @Override
    public boolean hasAutoExpandingGroups() {
        //This forces our group views (headers) to always render expanded.
        //Even attempting to programmatically collapse a group will not work.
        return true;
    }

    @Override
    public boolean isGroupSelectable(int groupPosition) {
        //This prevents a user from seeing any touch feedback when a group (header) is clicked.
        return false;
    }
}

The interrupt process is hardware and OS dependent. So you will have very different behavior depending on where you run your python script. For example, on Windows machines we have Ctrl+C (SIGINT) and Ctrl+Break (SIGBREAK).

So while SIGINT is present on all systems and can be handled and caught, the SIGBREAK signal is Windows specific (and can be disabled in CONFIG.SYS) and is really handled by the BIOS as an interrupt vector INT 1Bh, which is why this key is much more powerful than any other. So if you're using some *nix flavored OS, you will get different results depending on the implementation, since that signal is not present there, but others are. In Linux you can check what signals are available to you by:

$ kill -l
 1) SIGHUP       2) SIGINT       3) SIGQUIT      4) SIGILL       5) SIGTRAP
 6) SIGABRT      7) SIGEMT       8) SIGFPE       9) SIGKILL     10) SIGBUS
11) SIGSEGV     12) SIGSYS      13) SIGPIPE     14) SIGALRM     15) SIGTERM
16) SIGURG      17) SIGSTOP     18) SIGTSTP     19) SIGCONT     20) SIGCHLD
21) SIGTTIN     22) SIGTTOU     23) SIGIO       24) SIGXCPU     25) SIGXFSZ
26) SIGVTALRM   27) SIGPROF     28) SIGWINCH    29) SIGPWR      30) SIGUSR1
31) SIGUSR2     32) SIGRTMAX

So if you want to catch the CTRL+BREAK signal on a linux system you'll have to check to what POSIX signal they have mapped that key. Popular mappings are:

CTRL+\     = SIGQUIT 
CTRL+D     = SIGQUIT
CTRL+C     = SIGINT
CTRL+Z     = SIGTSTOP 
CTRL+BREAK = SIGKILL or SIGTERM or SIGSTOP

In fact, many more functions are available under Linux, where the SysRq (System Request) key can take on a life of its own...

Unit testing - is an approach of testing where the unit(class, method) is under control.

Test double - is not a primary object(from OOP world). It is a realisation which is created temporary to test, check or during development. Test doubles types:

• fake object is a real implementation of interface(protocol) or an extend which is using an inheritance or other approaches which can be used to create - is dependency. Usually it is created by developer as a simplest solution to substitute some dependency

• stub object is a bare object(0, nil and methods without logic) with extra state which is predefined(by developer) to define returned values. Usually it is created by framework

• mock object is very similar to stub object but the extra state is changed during program execution to check if something happened(method was called).

• spy object is a real object with a "partial mocking". It means that you work with a non-double object except mocked behavior

• dummy object is object which is necessary to run a test but no one variable or method of this object is not called.

stub vs mock

Martin Fowler said

There is a difference in that the stub uses state verification while the mock uses behavior verification.

[Mockito mock vs spy]

The Spring documentation says they're logged at DEBUG level:

All SQL issued by this class is logged at the DEBUG level under the category corresponding to the fully qualified class name of the template instance (typically JdbcTemplate, but it may be different if you are using a custom subclass of the JdbcTemplate class).

In XML terms, you need to configure the logger something like:

<category name="org.springframework.jdbc.core.JdbcTemplate">
    <priority value="debug" />
</category>

This subject was however discussed here a month ago and it seems not as easy to get to work as in Hibernate and/or it didn't return the expected information: Spring JDBC is not logging SQL with log4j This topic under each suggests to use P6Spy which can also be integrated in Spring according this article.

Faced similar error, any of the above solutions didn't help. There was a problem in the listner.ora file. By mistake I had added SID out of the SID_LIST see below(section between the stars *).

 SID_LIST_LISTENER =
      (SID_LIST =

        (SID_DESC =
          (SID_NAME = PLSExtProc)
          (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
          (PROGRAM = extproc)
        )
        (SID_DESC =
          (SID_NAME = CLRExtProc)
          (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
          (PROGRAM = extproc)
        )
        )

 *(SID_DESC =
           (SID_NAME = XE)
           (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)
         )*
    LISTENER =
      (DESCRIPTION_LIST =
        (DESCRIPTION =

          (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
        )
      )


    DEFAULT_SERVICE_LISTENER = (XE)

Corrected this error as below:

SID_LIST_LISTENER =
  (SID_LIST =
    (SID_DESC =
       (SID_NAME = XE)
       (ORACLE_HOME = C:\oraclexe\app\oracle\product\11.2.0\server)

    )
    )
LISTENER =
  (DESCRIPTION_LIST =
    (DESCRIPTION =

      (ADDRESS = (PROTOCOL = TCP)(HOST = 127.0.0.1)(PORT = 1521))
    )
  )


DEFAULT_SERVICE_LISTENER = (XE)

Stopped and the database

Stopped the listeners OracleServiceXE and OracleXETNSListener manually as it did not stop automatically by going to Control Panel\All Control Panel Items\Administrative Tools\Services. Restarted the database and it worked like a charm.

For the exact match use

    $("#HowYouKnow option").filter(function(index) { return $(this).text() === "GOOGLE"; }).attr('selected', 'selected');

contains is going to select the last match which might not be exact.

This would be an optimized way of doing it

StringBuilder sb = new StringBuilder();
for (String n : arr) { 
    sb.append("'").append(n).append("',");
}
if(sb.length()>0)
    sb.setLength(sbDiscrep.length()-1);
return sb.toString();

I hope this will help you.

Goto to your BIOS settings. Enable your Virtualization technology in your settings..

It solved my problem...

When the propagation setting is PROPAGATION_REQUIRED, a logical transaction scope is created for each method upon which the setting is applied. Each such logical transaction scope can determine rollback-only status individually, with an outer transaction scope being logically independent from the inner transaction scope. Of course, in case of standard PROPAGATION_REQUIRED behavior, all these scopes will be mapped to the same physical transaction. So a rollback-only marker set in the inner transaction scope does affect the outer transaction's chance to actually commit (as you would expect it to).

1. rebuild project in VS
2. copy project folder to iis folder, probably C:\inetpub\wwwroot\
3. in iis manager (run>inetmgr) add website, point to folder, point application pool based on your .net
4. add web service to created website, almost the same as 3.
5. INSTALL ASP for windows 7 and .net 4.0: c:\windows\microsoft.net framework\v4.(some numbers)\regiis.exe -i
6. check access to web service on your browser

If you know the key name simply do like this:

delete array['key_name']

Simplest method, use numeric format strings:

double total = "43.257"
MessageBox.Show(total.ToString("F"));

I have found that python-dotenv helps solve this issue pretty effectively. Your project structure ends up changing slightly, but the code in your notebook is a bit simpler and consistent across notebooks.

For your project, do a little install.

pipenv install python-dotenv

Then, project changes to:

+-- .env (this can be empty)
+-- ipynb
¦   +-- 20170609-Examine_Database_Requirements.ipynb
¦   +-- 20170609-Initial_Database_Connection.ipynb
+-- lib
    +-- __init__.py
    +-- postgres.py

And finally, your import changes to:

import os
import sys

from dotenv import find_dotenv


sys.path.append(os.path.dirname(find_dotenv()))

A +1 for this package is that your notebooks can be several directories deep. python-dotenv will find the closest one in a parent directory and use it. A +2 for this approach is that jupyter will load environment variables from the .env file on startup. Double whammy.

Using LEFT JOIN/IS NULL:

DELETE b FROM BLOB b 
  LEFT JOIN FILES f ON f.id = b.fileid 
      WHERE f.id IS NULL

Using NOT EXISTS:

DELETE FROM BLOB 
 WHERE NOT EXISTS(SELECT NULL
                    FROM FILES f
                   WHERE f.id = fileid)

Using NOT IN:

DELETE FROM BLOB
 WHERE fileid NOT IN (SELECT f.id 
                        FROM FILES f)

Warning

Whenever possible, perform DELETEs within a transaction (assuming supported - IE: Not on MyISAM) so you can use rollback to revert changes in case of problems.

use python version 3.6 or 3.7 but the important thing is you should install the python version of 64-bit.

I was stuck trying to implement this in typescript, all of the above would not work. I had to first cast the element in order for typescript to have access to the contentWindow.

let iframe = document.getElementById('frameId') as HTMLIFrameElement;
iframe.contentWindow.print();
