You can still use it (mysqli is just another way of communicating with the server, the SQL language itself is expanded, not changed). Prepared statements are safer, though - since you don't need to go through the trouble of properly escaping your values each time. You can leave them as they were, if you want to but the risk of sql piggybacking is reduced if you switch.

Peter's answer is my favourite, too.

If you are looking for more details there is a quite good overview, IMO, here.
Especially interesting is to read the benchmarks.

I pretty much like the (relatively) new java.time library: it's close to awesome, imho.

You can calculate a duration between two instants this way:

import java.time.*

Instant before = Instant.now();
// do stuff
Instant after = Instant.now();
long delta = Duration.between(before, after).toMillis(); // .toWhatsoever()

API is awesome, highly readable and intuitive.

Classes are thread-safe too. !

Using pure javascript Date(), we can calculate the numbers of years like below

document.getElementById('getYearsBtn').addEventListener('click', function () {_x000D_
  var enteredDate = document.getElementById('sampleDate').value;_x000D_
  // Below one is the single line logic to calculate the no. of years..._x000D_
  var years = new Date(new Date() - new Date(enteredDate)).getFullYear() - 1970;_x000D_
  console.log(years);_x000D_
});

<input type="text" id="sampleDate" value="1980/01/01">_x000D_
<div>Format: yyyy-mm-dd or yyyy/mm/dd</div><br>_x000D_
<button id="getYearsBtn">Calculate Years</button>

An asynchronous way to create directories recursively:

import fs from 'fs'

const mkdirRecursive = function(path, callback) {
  let controlledPaths = []
  let paths = path.split(
    '/' // Put each path in an array
  ).filter(
    p => p != '.' // Skip root path indicator (.)
  ).reduce((memo, item) => {
    // Previous item prepended to each item so we preserve realpaths
    const prevItem = memo.length > 0 ? memo.join('/').replace(/\.\//g, '')+'/' : ''
    controlledPaths.push('./'+prevItem+item)
    return [...memo, './'+prevItem+item]
  }, []).map(dir => {
    fs.mkdir(dir, err => {
      if (err && err.code != 'EEXIST') throw err
      // Delete created directory (or skipped) from controlledPath
      controlledPaths.splice(controlledPaths.indexOf(dir), 1)
      if (controlledPaths.length === 0) {
        return callback()
      }
    })
  })
}

// Usage
mkdirRecursive('./photos/recent', () => {
  console.log('Directories created succesfully!')
})

Use worksheet.find (worksheet is your worksheet) and use the row-range for its range-object. You can get the rangeobject like: worksheet.rows(rowIndex) as example

Then give find the required parameters it should find it for you fine. If I recall correctly, find returns the first match per default. I have no Excel at hand, so you have to look up find for yourself, sorry

I would advise against using a for-loop it is more fragile and ages slower than find.

math.e or from math import e (= 2.718281…)

The two expressions math.exp(x) and e**x are equivalent however:
Return e raised to the power x, where e = 2.718281… is the base of natural logarithms. This is usually more accurate than math.e ** x or pow(math.e, x). docs.python

for power use ** (3**2 = 9), not " ^ "
" ^ " is a bitwise XOR operator (& and, | or), it works logicaly with bits. So for example 10^4=14 (maybe unexpectedly) ? consider the bitwise depiction:

(0000 1010 ^ 0000 0100 = 0000 1110) programiz

As of Java 7:

System.lineSeparator()

Java API : System.lineSeparator

Returns the system-dependent line separator string. It always returns the same value - the initial value of the system property line.separator. On UNIX systems, it returns "\n"; on Microsoft Windows systems it returns "\r\n".

You have to do this to echo it:

echo $row['note'];

(The data is coming as an array)

The difficulty with DDD samples is that they're often very domain specific and the technical implementation of the resulting system doesn't always show the design decisions and transitions that were made in modelling the domain, which is really at the core of DDD. DDD is much more about the process than it is the code. (as some say, the best DDD sample is the book itself!)

That said, a well commented sample app should at least reveal some of these decisions and give you some direction in terms of matching up your domain model with the technical patterns used to implement it.

You haven't specified which language you're using, but I'll give you a few in a few different languages:

DDDSample - a Java sample that reflects the examples Eric Evans talks about in his book. This is well commented and shows a number of different methods of solving various problems with separate bounded contexts (ie, the presentation layer). It's being actively worked on, so check it regularly for updates.

dddps - Tim McCarthy's sample C# app for his book, .NET Domain-Driven Design with C#

S#arp Architecture - a pragmatic C# example, not as "pure" a DDD approach perhaps due to its lack of a real domain problem, but still a nice clean approach.

With all of these sample apps, it's probably best to check out the latest trunk versions from SVN/whatever to really get an idea of the thinking and technology patterns as they should be updated regularly.

'entityManager.unwrap(Session.class)' is used to get session from EntityManager.

@Repository
@Transactional
public class EmployeeRepository {

  @PersistenceContext
  private EntityManager entityManager;

  public Session getSession() {
    Session session = entityManager.unwrap(Session.class);
    return session;
  }

This is actually on the main page of nltk.org:

>>> import nltk
>>> sentence = """At eight o'clock on Thursday morning
... Arthur didn't feel very good."""
>>> tokens = nltk.word_tokenize(sentence)
>>> tokens
['At', 'eight', "o'clock", 'on', 'Thursday', 'morning',
'Arthur', 'did', "n't", 'feel', 'very', 'good', '.']

The [0] needs to be inside the ).

A final class is a class that can't be extended. Also methods could be declared as final to indicate that cannot be overridden by subclasses.

Preventing the class from being subclassed could be particularly useful if you write APIs or libraries and want to avoid being extended to alter base behaviour.

for those who got here because the title of the question:

I use Reply-To: address with webforms. when someone fills out the form, the webpage sends an automatic email to the page's owner. the From: is the automatic mail sender's address, so the owner knows it is from the webform. but the Reply-To: address is the one filled in in the form by the user, so the owner can just hit reply to contact them.

I came here with the same Error, though one with a different origin.

It is caused by unsupported float index in 1.12.0 and newer numpy versions even if the code should be considered as valid.

An int type is expected, not a np.float64

Solution: Try to install numpy 1.11.0

sudo pip install -U numpy==1.11.0.

You can call the method getBoundingClientRect() on a reference to the element. Then you can examine the top, left, right and/or bottom properties...

var offsets = document.getElementById('11a').getBoundingClientRect();
var top = offsets.top;
var left = offsets.left;

If using jQuery, you can use the more succinct code...

var offsets = $('#11a').offset();
var top = offsets.top;
var left = offsets.left;

I cannot believe this is still a problem in 2014. I just had this issue when refreshing a fixed position caption box on the lower-left hand of the page while scrolling, the caption would 'ghost' its way up the screen. After trying everything above without success, I noticed a lot of things were either slow/causing issues due to creating very short DOM relayouts etc causing somewhat unnatural feeling scrolling etc...

I ended up making a fixed position, full-size div with pointer-events: none and applying danorton's answer to that element, which seems to force a redraw on the whole screen without interfering with the DOM.

HTML:

<div id="redraw-fix"></div>

CSS:

div#redraw-fix {
    position: fixed;
    top: 0;
    right: 0;
    bottom: 0;
    left: 0;
    z-index: 25;
    pointer-events: none;
    display: block;
}

JS:

sel = document.getElementById('redraw-fix');
sel.style.display='none';
sel.offsetHeight; // no need to store this anywhere, the reference is enough
sel.style.display='block';

There are several other things you can do, such as selecting new fonts:

\documentclass[10pt,a4paper]{article}
% ... lots of packages e.g. babel, microtype, fontenc, inputenc &c.
\usepackage{color}    % Leave this out if you care about B/W printing, obviously.
\usepackage{upquote}  % Turns curly quotes in verbatim text into straight quotes. 
                      % People who have to copy/paste code from the PDF output 
                      % will love you for this. Or perhaps more accurately: 
                      % They will not hate you/hate you less.
\usepackage{beramono} % Or some other package that provides a fixed width font. q.v.
                      % http://www.tug.dk/FontCatalogue/typewriterfonts.html
\usepackage{listings} 
\lstset {                 % A rudimentary config that shows off some features.
    language=Java,
    basicstyle=\ttfamily, % Without beramono, we'd get cmtt, the teletype font.
    commentstyle=\textit, % cmtt doesn't do italics. It might do slanted text though.
    \keywordstyle=        % Nor does cmtt do bold text.
        \color{blue}\bfseries,
    \tabsize=4            % Or whatever you use in your editor, I suppose.
}
\begin{document} 
\begin{lstlisting}
public final int ourAnswer() { return 42; /* Our final answer */ }
\end{lstlisting} 
\end{document}

The only place I have successfully make it work is by searching in:

...\Qt\{5.9; or your version}\mingw{53_32; or your version}\mkspecs\win32-g++\qmake.conf:

Then at the line:

QMAKE_CFLAGS           += -fno-keep-inline-dllexport

Edit :

QMAKE_CFLAGS           += -fno-keep-inline-dllexport -std=c++11

A simple solution using fscanf:

void read_ints (const char* file_name)
{
  FILE* file = fopen (file_name, "r");
  int i = 0;

  fscanf (file, "%d", &i);    
  while (!feof (file))
    {  
      printf ("%d ", i);
      fscanf (file, "%d", &i);      
    }
  fclose (file);        
}

Try the :host > /deep/ :

Add the following to the parent.component.less file

:host {
    /deep/ app-child-component {
       //your child style
    }
}

Replace the app-child-component by your child selector

<script type="text/javascript">
    $(document).ready(function(){
        $(".scroll-element").click(function(){
            $('html,body').animate({
                scrollTop: $('.our_companies').offset().top
            }, 1000);

            return false;
        });
    })
</script>

This answer concerns developers for Windows. You want to pick an XML parsing module that does NOT depend on node-expat. Node-expat requires node-gyp and node-gyp requires you to install Visual Studio on your machine. If your machine is a Windows Server, you definitely don't want to install Visual Studio on it.

So, which XML parsing module to pick?

Save yourself a lot of trouble and use either xml2js or xmldoc. They depend on sax.js which is a pure Javascript solution that doesn't require node-gyp.

Both libxmljs and xml-stream require node-gyp. Don't pick these unless you already have Visual Studio on your machine installed or you don't mind going down that road.

Update 2015-10-24: it seems somebody found a solution to use node-gyp on Windows without installing VS: https://github.com/nodejs/node-gyp/issues/629#issuecomment-138276692

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

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

var georgeEmail = people[1].Email;

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

There are defined tuples for up to 8 members.

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

The stacks and recursion elimination article captures the idea of externalizing the stack frame on heap, but does not provide a straightforward and repeatable way to convert. Below is one.

While converting to iterative code, one must be aware that the recursive call may happen from an arbitrarily deep code block. Its not just the parameters, but also the point to return to the logic that remains to be executed and the state of variables which participate in subsequent conditionals, which matter. Below is a very simple way to convert to iterative code with least changes.

Consider this recursive code:

struct tnode
{
    tnode(int n) : data(n), left(0), right(0) {}
    tnode *left, *right;
    int data;
};

void insertnode_recur(tnode *node, int num)
{
    if(node->data <= num)
    {
        if(node->right == NULL)
            node->right = new tnode(num);
        else
            insertnode(node->right, num);
    }
    else
    {
        if(node->left == NULL)
            node->left = new tnode(num);
        else
            insertnode(node->left, num);
    }    
}

Iterative code:

// Identify the stack variables that need to be preserved across stack 
// invocations, that is, across iterations and wrap them in an object
struct stackitem 
{ 
    stackitem(tnode *t, int n) : node(t), num(n), ra(0) {}
    tnode *node; int num;
    int ra; //to point of return
};

void insertnode_iter(tnode *node, int num) 
{
    vector<stackitem> v;
    //pushing a stackitem is equivalent to making a recursive call.
    v.push_back(stackitem(node, num));

    while(v.size()) 
    {
        // taking a modifiable reference to the stack item makes prepending 
        // 'si.' to auto variables in recursive logic suffice
        // e.g., instead of num, replace with si.num.
        stackitem &si = v.back(); 
        switch(si.ra)
        {
        // this jump simulates resuming execution after return from recursive 
        // call 
            case 1: goto ra1;
            case 2: goto ra2;
            default: break;
        } 

        if(si.node->data <= si.num)
        {
            if(si.node->right == NULL)
                si.node->right = new tnode(si.num);
            else
            {
                // replace a recursive call with below statements
                // (a) save return point, 
                // (b) push stack item with new stackitem, 
                // (c) continue statement to make loop pick up and start 
                //    processing new stack item, 
                // (d) a return point label
                // (e) optional semi-colon, if resume point is an end 
                // of a block.

                si.ra=1;
                v.push_back(stackitem(si.node->right, si.num));
                continue; 
ra1:            ;         
            }
        }
        else
        {
            if(si.node->left == NULL)
                si.node->left = new tnode(si.num);
            else
            {
                si.ra=2;                
                v.push_back(stackitem(si.node->left, si.num));
                continue;
ra2:            ;
            }
        }

        v.pop_back();
    }
}

Notice how the structure of the code still remains true to the recursive logic and modifications are minimal, resulting in less number of bugs. For comparison, I have marked the changes with ++ and --. Most of the new inserted blocks except v.push_back, are common to any converted iterative logic

void insertnode_iter(tnode *node, int num) 
{

    vector<stackitem> v;
    v.push_back(stackitem(node, num));

    while(v.size())

        switch(si.ra)
        {
            case 1: goto ra1;
            case 2: goto ra2;
            default: break;
        }

            else
            {

                si.ra=1;
                v.push_back(stackitem(si.node->right, si.num));
                continue; 
ra1:            ;

For Angular 5 and above, we can use HttpInterceptor for generalizing the request and response operations. This helps us avoid duplicating:

1) Common headers

2) Specifying response type

3) Querying request

import { Injectable } from '@angular/core';
import {
  HttpRequest,
  HttpHandler,
  HttpEvent,
  HttpInterceptor,
  HttpResponse,
  HttpErrorResponse
} from '@angular/common/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/add/operator/do';

@Injectable()
export class AuthHttpInterceptor implements HttpInterceptor {

  requestCounter: number = 0;
  constructor() {
  }

  intercept(request: HttpRequest<any>, next: HttpHandler): Observable<HttpEvent<any>> {

    request = request.clone({
      responseType: 'json',
      setHeaders: {
        Authorization: `Bearer token_value`,
        'Content-Type': 'application/x-www-form-urlencoded; charset=UTF-8'
      }
    });

    return next.handle(request).do((event: HttpEvent<any>) => {
      if (event instanceof HttpResponse) {
        // do stuff with response if you want
      }
    }, (err: any) => {
      if (err instanceof HttpErrorResponse) {
        // do stuff with response error if you want
      }
    });
  }
}

We can use this AuthHttpInterceptor class as a provider for the HttpInterceptors:

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppComponent } from './app.component';
import { AppRoutingModule } from './app.routing-module';
import { AuthHttpInterceptor } from './services/auth-http.interceptor';
import { HttpClientModule, HTTP_INTERCEPTORS } from '@angular/common/http';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    HttpClientModule,
    BrowserAnimationsModule,
  ],
  providers: [
    {
      provide: HTTP_INTERCEPTORS,
      useClass: AuthHttpInterceptor,
      multi: true
    }
  ],
  exports: [],
  bootstrap: [AppComponent]
})
export class AppModule {
}

Although there is an accepted answer I would want to add that as of Hive 0.14, record level operations are allowed. The correct syntax and query would be:

INSERT INTO TABLE tweet_table VALUES ('data');

Really simple:

remove-item -path <type in file or directory name>, press Enter

In my case this works fine:

source:function(request, response){
    var numSumResult = 0;
    response(
        $.map(tblData, function(rowData) {
            if (numSumResult < 10) {
                numSumResult ++;
                return {
                    label:          rowData.label,
                    value:          rowData.value,
                }
            }
        })
    );
},

The Following:

.show-grid [class*="span"] {

means that all child elements of '.show-grid' with a class that CONTAINS the word 'span' in it will acquire those CSS properties.

<div class="show-grid">
  <div class="span">.span</div>
  <div class="span6">span6</div>
  <div class="attention-span">attention</div>
  <div class="spanish">spanish</div>
  <div class="mariospan">mariospan</div>
  <div class="espanol">espanol</div>

  <div>
    <div class="span">.span</div>
  </div>

  <p class="span">span</p>
  <span class="span">I do GET HIT</span>

  <span>I DO NOT GET HIT since I need a class of 'span'</span>
</div>

<div class="span">I DO NOT GET HIT since I'm outside of .show-grid</span>

All of the elements get hit except for the <span> by itself.

In Regards to Bootstrap:

• span6 : this was Bootstrap 2's scaffolding technique which divided a section into a horizontal grid, based on parts of 12. Thus span6 would have a width of 50%.
• In the current day implementation of Bootstrap (v.3 and v.4), you now use the .col-* classes (e.g. col-sm-6), which also specifies a media breakpoint to handle responsiveness when the window shrinks below a certain size. Check Bootstrap 4.1 and Bootstrap 3.3.7 for more documentation. I would recommend going with a later Bootstrap nowadays

Try this: http://jsbeautifier.org/

I tested with your code and worked as good as possible. =D

I submit my own implementation, which handles null values and should be more performant on account of using array lookup tables, manual hex conversion, and avoiding switch statements.

I have a solution from a while ago that I kept improving. Also searches within XML columns if told to do so, or searches integer values if providing a integer only string.

/* Reto Egeter, fullparam.wordpress.com */

SET @FullRowResultRows = 3

Just before executing the query: alter session set NLS_DATE_FORMAT = "DD.MM.YYYY HH24:MI:SS"; or whichever format you are giving the information to the date function. This should fix the ORA error

this code worked for me:

window.frames['myIFrame'].contentDocument.getElementById('myIFrameElemId');

If you are looking for full control of Google Analytics's new tracking code, you could use my very own Angular-GA.

It makes ga available through injection, so it's easy to test. It doesn't do any magic, apart from setting the path on every routeChange. You still have to send the pageview like here.

app.run(function ($rootScope, $location, ga) {
    $rootScope.$on('$routeChangeSuccess', function(){
        ga('send', 'pageview');
    });
});

Additionaly there is a directive ga which allows to bind multiple analytics functions to events, like this:

<a href="#" ga="[['set', 'metric1', 10], ['send', 'event', 'player', 'play', video.id]]"></a>

Using a Messenger is another simple way to communicate between a Service and an Activity.

In the Activity, create a Handler with a corresponding Messenger. This will handle messages from your Service.

class ResponseHandler extends Handler {
    @Override public void handleMessage(Message message) {
            Toast.makeText(this, "message from service",
                    Toast.LENGTH_SHORT).show();
    }
}
Messenger messenger = new Messenger(new ResponseHandler());

The Messenger can be passed to the service by attaching it to a Message:

Message message = Message.obtain(null, MyService.ADD_RESPONSE_HANDLER);
message.replyTo = messenger;
try {
    myService.send(message);
catch (RemoteException e) {
    e.printStackTrace();
}

A full example can be found in the API demos: MessengerService and MessengerServiceActivity. Refer to the full example for how MyService works.

You can use the function MROUND(<reference cell>, <round to multiple of digit needed>).

Example:

1. For a value A1 = 21 round to multiple of 10 it would be written as =MROUND(A1,10) for which Result = 20

2. For a value Z4 = 55.1 round to multiple of 10 it would be written as =MROUND(Z4,10) for which Result = 60

Here's a code excerpt we're using in our app to set request headers. You'll note we set the CONTENT_TYPE header only on a POST or PUT, but the general method of adding headers (via a request interceptor) is used for GET as well.

/**
 * HTTP request types
 */
public static final int POST_TYPE   = 1;
public static final int GET_TYPE    = 2;
public static final int PUT_TYPE    = 3;
public static final int DELETE_TYPE = 4;

/**
 * HTTP request header constants
 */
public static final String CONTENT_TYPE         = "Content-Type";
public static final String ACCEPT_ENCODING      = "Accept-Encoding";
public static final String CONTENT_ENCODING     = "Content-Encoding";
public static final String ENCODING_GZIP        = "gzip";
public static final String MIME_FORM_ENCODED    = "application/x-www-form-urlencoded";
public static final String MIME_TEXT_PLAIN      = "text/plain";

private InputStream performRequest(final String contentType, final String url, final String user, final String pass,
    final Map<String, String> headers, final Map<String, String> params, final int requestType) 
            throws IOException {

    DefaultHttpClient client = HTTPClientFactory.newClient();

    client.getParams().setParameter(HttpProtocolParams.USER_AGENT, mUserAgent);

    // add user and pass to client credentials if present
    if ((user != null) && (pass != null)) {
        client.getCredentialsProvider().setCredentials(AuthScope.ANY, new UsernamePasswordCredentials(user, pass));
    }

    // process headers using request interceptor
    final Map<String, String> sendHeaders = new HashMap<String, String>();
    if ((headers != null) && (headers.size() > 0)) {
        sendHeaders.putAll(headers);
    }
    if (requestType == HTTPRequestHelper.POST_TYPE || requestType == HTTPRequestHelper.PUT_TYPE ) {
        sendHeaders.put(HTTPRequestHelper.CONTENT_TYPE, contentType);
    }
    // request gzip encoding for response
    sendHeaders.put(HTTPRequestHelper.ACCEPT_ENCODING, HTTPRequestHelper.ENCODING_GZIP);

    if (sendHeaders.size() > 0) {
        client.addRequestInterceptor(new HttpRequestInterceptor() {

            public void process(final HttpRequest request, final HttpContext context) throws HttpException,
                IOException {
                for (String key : sendHeaders.keySet()) {
                    if (!request.containsHeader(key)) {
                        request.addHeader(key, sendHeaders.get(key));
                    }
                }
            }
        });
    }

    //.... code omitted ....//

}

This solution is no more supported since jQuery 1.8 as we can read on the blog here:

$(element).data(“events”): This is now removed in 1.8, but you can still get to the events data for debugging purposes via $._data(element, "events"). Note that this is not a supported public interface; the actual data structures may change incompatibly from version to version.

So, you should unbind/rebind it or simply, use a boolean to determine if your event as been attached or not (which is in my opinion the best solution).

Another solution is

SELECT 
  ROUND((TRUNC(SYSDATE) - TRUNC(SYSDATE, 'YEAR')) / 7,0) CANTWEEK,
  NEXT_DAY(SYSDATE, 'SUNDAY') - 7 FIRSTDAY,
  NEXT_DAY(SYSDATE, 'SUNDAY') - 1 LASTDAY
FROM DUAL

You must concat the cantweek with the year

Try:

insert into account_type_standard (account_type_Standard_id, tax_status_id, recipient_id)
select account_type_standard_seq.nextval,
       ts.tax_status_id, 
       ( select r.recipient_id
         from recipient r
         where r.recipient_code = ?
       )
from tax_status ts
where ts.tax_status_code = ?

For what it's worth, my groovy spike seems to work with both UTF-8 and ISO-8859-1 character encodings. Not sure what will happen when a non zxing decoder tries to decode the UTF-8 encoded image though... probably varies depending on the device.

        Result result = new MultiFormatReader().decode(binaryBitmap, hints)

        result.getText()        
    }

}

tl;dr Swift 1.0 is now as fast as C by this benchmark using the default release optimisation level [-O].

Here is an in-place quicksort in Swift Beta:

func quicksort_swift(inout a:CInt[], start:Int, end:Int) {
    if (end - start < 2){
        return
    }
    var p = a[start + (end - start)/2]
    var l = start
    var r = end - 1
    while (l <= r){
        if (a[l] < p){
            l += 1
            continue
        }
        if (a[r] > p){
            r -= 1
            continue
        }
        var t = a[l]
        a[l] = a[r]
        a[r] = t
        l += 1
        r -= 1
    }
    quicksort_swift(&a, start, r + 1)
    quicksort_swift(&a, r + 1, end)
}

And the same in C:

void quicksort_c(int *a, int n) {
    if (n < 2)
        return;
    int p = a[n / 2];
    int *l = a;
    int *r = a + n - 1;
    while (l <= r) {
        if (*l < p) {
            l++;
            continue;
        }
        if (*r > p) {
            r--;
            continue;
        }
        int t = *l;
        *l++ = *r;
        *r-- = t;
    }
    quicksort_c(a, r - a + 1);
    quicksort_c(l, a + n - l);
}

Both work:

var a_swift:CInt[] = [0,5,2,8,1234,-1,2]
var a_c:CInt[] = [0,5,2,8,1234,-1,2]

quicksort_swift(&a_swift, 0, a_swift.count)
quicksort_c(&a_c, CInt(a_c.count))

// [-1, 0, 2, 2, 5, 8, 1234]
// [-1, 0, 2, 2, 5, 8, 1234]

Both are called in the same program as written.

var x_swift = CInt[](count: n, repeatedValue: 0)
var x_c = CInt[](count: n, repeatedValue: 0)
for var i = 0; i < n; ++i {
    x_swift[i] = CInt(random())
    x_c[i] = CInt(random())
}

let swift_start:UInt64 = mach_absolute_time();
quicksort_swift(&x_swift, 0, x_swift.count)
let swift_stop:UInt64 = mach_absolute_time();

let c_start:UInt64 = mach_absolute_time();
quicksort_c(&x_c, CInt(x_c.count))
let c_stop:UInt64 = mach_absolute_time();

This converts the absolute times to seconds:

static const uint64_t NANOS_PER_USEC = 1000ULL;
static const uint64_t NANOS_PER_MSEC = 1000ULL * NANOS_PER_USEC;
static const uint64_t NANOS_PER_SEC = 1000ULL * NANOS_PER_MSEC;

mach_timebase_info_data_t timebase_info;

uint64_t abs_to_nanos(uint64_t abs) {
    if ( timebase_info.denom == 0 ) {
        (void)mach_timebase_info(&timebase_info);
    }
    return abs * timebase_info.numer  / timebase_info.denom;
}

double abs_to_seconds(uint64_t abs) {
    return abs_to_nanos(abs) / (double)NANOS_PER_SEC;
}

Here is a summary of the compiler's optimazation levels:

[-Onone] no optimizations, the default for debug.
[-O]     perform optimizations, the default for release.
[-Ofast] perform optimizations and disable runtime overflow checks and runtime type checks.

Time in seconds with [-Onone] for n=10_000:

Swift:            0.895296452
C:                0.001223848

Here is Swift's builtin sort() for n=10_000:

Swift_builtin:    0.77865783

Here is [-O] for n=10_000:

Swift:            0.045478346
C:                0.000784666
Swift_builtin:    0.032513488

As you can see, Swift's performance improved by a factor of 20.

As per mweathers' answer, setting [-Ofast] makes the real difference, resulting in these times for n=10_000:

Swift:            0.000706745
C:                0.000742374
Swift_builtin:    0.000603576

And for n=1_000_000:

Swift:            0.107111846
C:                0.114957179
Swift_sort:       0.092688548

For comparison, this is with [-Onone] for n=1_000_000:

Swift:            142.659763258
C:                0.162065333
Swift_sort:       114.095478272

So Swift with no optimizations was almost 1000x slower than C in this benchmark, at this stage in its development. On the other hand with both compilers set to [-Ofast] Swift actually performed at least as well if not slightly better than C.

It has been pointed out that [-Ofast] changes the semantics of the language, making it potentially unsafe. This is what Apple states in the Xcode 5.0 release notes:

A new optimization level -Ofast, available in LLVM, enables aggressive optimizations. -Ofast relaxes some conservative restrictions, mostly for floating-point operations, that are safe for most code. It can yield significant high-performance wins from the compiler.

They all but advocate it. Whether that's wise or not I couldn't say, but from what I can tell it seems reasonable enough to use [-Ofast] in a release if you're not doing high-precision floating point arithmetic and you're confident no integer or array overflows are possible in your program. If you do need high performance and overflow checks / precise arithmetic then choose another language for now.

BETA 3 UPDATE:

n=10_000 with [-O]:

Swift:            0.019697268
C:                0.000718064
Swift_sort:       0.002094721

Swift in general is a bit faster and it looks like Swift's built-in sort has changed quite significantly.

FINAL UPDATE:

[-Onone]:

Swift:   0.678056695
C:       0.000973914

[-O]:

Swift:   0.001158492
C:       0.001192406

[-Ounchecked]:

Swift:   0.000827764
C:       0.001078914

Thought to write a code to demonstrate the isAlive() , getState() methods, this example monitors a thread still it terminates(dies).

The following code will get the date minus timezone offset:

    return Date.from(gmt0.toInstant());
}

@Test

    ZonedDateTime now = ZonedDateTime.now();
    Date dateAtSystemZone = Date.from(now.toInstant());
    Date dateAtGmt0 = toGmt0(now);

    SimpleDateFormat sdfWithoutZone = new SimpleDateFormat("yyyy-MM-dd HH:mm:ss.SSS");

output :

dateAtGmt0                = Thu Apr 23 06:03:36 CST 2020
diffInMillis              = 28800000

dateWithSystemZone.format = 2020-04-23 14:03:36.140
dateAtGmt0.format         = 2020-04-23 06:03:36.140

dateFormatWithGmt0        = 2020-04-23 06:03:36.140

My system is at GMT+8, so diffInMillis = 28800000 = 8 * 60 * 60 * 1000?

Update your current Android Studio to Android Studio 2.0 And also update system images.

Android Studio 2.0 emulator runs ~3x faster than Android’s previous emulator, and with ADB enhancements you can now push apps and data 10x faster to the emulator than to a physical device. Like a physical device, the official Android emulator also includes Google Play Services built-in, so you can test out more API functionality. Finally, the new emulator has rich new features to manage calls, battery, network, GPS, and more.

By my experience the best way is:

<xsl:when test="not(string(categoryName))">
    <xsl:value-of select="other" />
</xsl:when>
<otherwise>
    <xsl:value-of select="categoryName" />
</otherwise>

This is what I used.

$('#foo').popover({
    placement : 'bottom',
    title : 'Title',
    content : '<div id="popOverBox"><img src="http://i.telegraph.co.uk/multimedia/archive/01515/alGore_1515233c.jpg" /></div>'
});

and for the HTML

<b id="foo" rel="popover">text goes here</b>

You were on the right track with response.getOutputStream(), but you're not using its output anywhere in your code. Essentially what you need to do is to stream the PDF file's bytes directly to the output stream and flush the response. In Spring you can do it like this:

@RequestMapping(value="/getpdf", method=RequestMethod.POST)
public ResponseEntity<byte[]> getPDF(@RequestBody String json) {
    // convert JSON to Employee 
    Employee emp = convertSomehow(json);

    // generate the file
    PdfUtil.showHelp(emp);

    // retrieve contents of "C:/tmp/report.pdf" that were written in showHelp
    byte[] contents = (...);

    HttpHeaders headers = new HttpHeaders();
    headers.setContentType(MediaType.APPLICATION_PDF);
    // Here you have to set the actual filename of your pdf
    String filename = "output.pdf";
    headers.setContentDispositionFormData(filename, filename);
    headers.setCacheControl("must-revalidate, post-check=0, pre-check=0");
    ResponseEntity<byte[]> response = new ResponseEntity<>(contents, headers, HttpStatus.OK);
    return response;
}

Notes:

• use meaningful names for your methods: naming a method that writes a PDF document showHelp is not a good idea
• reading a file into a byte[]: example here
• I'd suggest adding a random string to the temporary PDF file name inside showHelp() to avoid overwriting the file if two users send a request at the same time

As others mentioned, Justin's answer was close, but not quite right. I tested this using Visual Studio's "Paste JSON as C# Classes"

{
    "foos" : [
        {
            "prop1":"value1",
            "prop2":"value2"
        },
        {
            "prop1":"value3", 
            "prop2":"value4"
        }
    ]
}

A solution that nobody mentioned is use white-space: nowrap for the table and add overflow-x to the wrapper.

(http://jsfiddle.net/xc7jLuyx/11/)

CSS

.wrapper { overflow-x: auto; }
.wrapper table { white-space: nowrap }

HTML

<div class="wrapper">
    <table></table>
</div>

This is an ideal scenario if you don't want rows with multiple lines.
To add break lines you need to use <br/>.

My bad, I had missed one part of the question.

Best, cleanest way is to use a UDF. Explanation within the code.

// create some example data...BY DataFrame
// note, third record has an empty string
case class Stuff(a:String,b:Int)
val d= sc.parallelize(Seq( ("a",1),("b",2),
     ("",3) ,("d",4)).map { x => Stuff(x._1,x._2)  }).toDF

// now the good stuff.
import org.apache.spark.sql.functions.udf
// function that returns 0 is string empty 
val func = udf( (s:String) => if(s.isEmpty) 0 else 1 )
// create new dataframe with added column named "notempty"
val r = d.select( $"a", $"b", func($"a").as("notempty") )

    scala> r.show
+---+---+--------+
|  a|  b|notempty|
+---+---+--------+
|  a|  1|    1111|
|  b|  2|    1111|
|   |  3|       0|
|  d|  4|    1111|
+---+---+--------+

Here is the cleanest way to do this:

<p ng-show="{{foo === undefined}}">Show this if $scope.foo === undefined</p>

No need to create a helper function in the controller!

The specific way to run it depends on whether you gave the image a tag/name or not.

$ docker images
REPOSITORY          TAG                 ID                  CREATED             SIZE
ubuntu              12.04               8dbd9e392a96        4 months ago        131.5 MB (virtual 131.5 MB)

With a name (let's use Ubuntu):

$ docker run -i -t ubuntu:12.04 /bin/bash

Without a name, just using the ID:

$ docker run -i -t 8dbd9e392a96 /bin/bash

Please see Docker run reference for more information.

Python 3

In Python 3.x basestring is not available anymore, as str is the sole string type (with the semantics of Python 2.x's unicode).

So the check in Python 3.x is just:

isinstance(obj_to_test, str)

This follows the fix of the official 2to3 conversion tool: converting basestring to str.

Deleting and Recreating a project with same name is tricky. If you try to follow above suggested steps and try to create a project with same name as the one you just deleted, you will run into error like

'C:/xxxxxx/pom.xml' already exists in VFS

Here is what I found would work.

1. Remove module
2. File -> Invalidate Cache (at this point the Intelli IDEA wants to restart)
3. Close project
4. Delete the folder form system explorer.
5. Now you can create a project with same name as before.

Open SQL Developer. Go to Tools -> Preferences -> Databases -> Advanced Then explicitly set the Tnsnames Directory

My TNSNAMES was set up correctly and I could connect to Toad, SQL*Plus etc. but I needed to do this to get SQL Developer to work. Perhaps it was a Win 7 issue as it was a pain to install too.

This is one way to do it:

SQL> set serveroutput on
SQL> CREATE OR REPLACE TYPE MyType AS VARRAY(200) OF VARCHAR2(50);
  2  /

Type created

SQL> CREATE OR REPLACE PROCEDURE testing (t_in MyType) IS
  2  BEGIN
  3    FOR i IN 1..t_in.count LOOP
  4      dbms_output.put_line(t_in(i));
  5    END LOOP;
  6  END;
  7  /

Procedure created

SQL> DECLARE
  2    v_t MyType;
  3  BEGIN
  4    v_t := MyType();
  5    v_t.EXTEND(10);
  6    v_t(1) := 'this is a test';
  7    v_t(2) := 'A second test line';
  8    testing(v_t);
  9  END;
 10  /

this is a test
A second test line

To expand on my comment to @dcp's answer, here's how you could implement the solution proposed there if you wanted to use an associative array:

SQL> CREATE OR REPLACE PACKAGE p IS
  2    TYPE p_type IS TABLE OF VARCHAR2(50) INDEX BY BINARY_INTEGER;
  3  
  4    PROCEDURE pp (inp p_type);
  5  END p;
  6  /

Package created
SQL> CREATE OR REPLACE PACKAGE BODY p IS
  2    PROCEDURE pp (inp p_type) IS
  3    BEGIN
  4      FOR i IN 1..inp.count LOOP
  5        dbms_output.put_line(inp(i));
  6      END LOOP;
  7    END pp;
  8  END p;
  9  /

Package body created
SQL> DECLARE
  2    v_t p.p_type;
  3  BEGIN
  4    v_t(1) := 'this is a test of p';
  5    v_t(2) := 'A second test line for p';
  6    p.pp(v_t);
  7  END;
  8  /

this is a test of p
A second test line for p

PL/SQL procedure successfully completed

SQL> 

This trades creating a standalone Oracle TYPE (which cannot be an associative array) with requiring the definition of a package that can be seen by all in order that the TYPE it defines there can be used by all.

DECLARE   @UserOptions TABLE(SetOption varchar(100), Value varchar(100))
DECLARE   @IsolationLevel varchar(100)

INSERT    @UserOptions
EXEC('DBCC USEROPTIONS WITH NO_INFOMSGS')

SELECT    @IsolationLevel = Value
FROM      @UserOptions
WHERE     SetOption = 'isolation level'

-- Do whatever you want with the variable here...  
PRINT     @IsolationLevel

One might consider adding this line to ~/.bash_profile (or similar) in order to can quickly get the current UTC both as current time and as seconds since the epoch.

alias utc='date -u && date -u +%s'

If there were a tie at the fourth position for mtcars$mpg then this should return all the ties:

top_mpg <- mtcars[ mtcars$mpg >= mtcars$mpg[order(mtcars$mpg, decreasing=TRUE)][4] , ]

> top_mpg
                mpg cyl disp  hp drat    wt  qsec vs am gear carb
Fiat 128       32.4   4 78.7  66 4.08 2.200 19.47  1  1    4    1
Honda Civic    30.4   4 75.7  52 4.93 1.615 18.52  1  1    4    2
Toyota Corolla 33.9   4 71.1  65 4.22 1.835 19.90  1  1    4    1
Lotus Europa   30.4   4 95.1 113 3.77 1.513 16.90  1  1    5    2

Since there is a tie at the 3-4 position you can test it by changing 4 to a 3, and it still returns 4 items. This is logical indexing and you might need to add a clause that removes the NA's or wrap which() around the logical expression. It's not much more difficult to do this "by" cyl:

 Reduce(rbind,  by(mtcars, mtcars$cyl, 
        function(d) d[ d$mpg >= d$mpg[order(d$mpg, decreasing=TRUE)][4] , ]) )

Incorporating my suggestion to @Ista:

It used to be installed with the .NET framework. MsBuild v12.0 (2013) is now bundled as a stand-alone utility and has it's own installer.

http://www.microsoft.com/en-us/download/confirmation.aspx?id=40760

To reference the location of MsBuild.exe from within an MsBuild script, use the default $(MsBuildToolsPath) property.

To insert a CR into XML, you need to use its character entity 
.

This is because compliant XML parsers must, before parsing, translate CRLF and any CR not followed by a LF to a single LF. This behavior is defined in the End-of-Line handling section of the XML 1.0 specification.

There is many ways to use it and i recomend you to see this documentation about String Format.

http://developer.android.com/intl/pt-br/reference/java/util/Formatter.html

But, if you need only one variable, you'll need to use %[type] where [type] could be any Flag (see Flag types inside site above). (i.e. "My name is %s" or to set my name UPPERCASE, use this "My name is %S")

<string name="welcome_messages">Hello, %1$S! You have %2$d new message(s) and your quote is %3$.2f%%.</string>

Hello, ANDROID! You have 1 new message(s) and your quote is 80,50%.

open the sql file on Notepad++ and ctrl + H. Then you put "utf8mb4" on search and "utf8" on replace. The issue will be fixed then.

While you unfortunately cannot convert an existing member function pointer to a plain function pointer, you can create an adapter function template in a fairly straightforward way that wraps a member function pointer known at compile-time in a normal function like this:

template <class Type>
struct member_function;

template <class Type, class Ret, class... Args>
struct member_function<Ret(Type::*)(Args...)>
{
    template <Ret(Type::*Func)(Args...)>
    static Ret adapter(Type &obj, Args&&... args)
    {
        return (obj.*Func)(std::forward<Args>(args)...);
    }
};

template <class Type, class Ret, class... Args>
struct member_function<Ret(Type::*)(Args...) const>
{
    template <Ret(Type::*Func)(Args...) const>
    static Ret adapter(const Type &obj, Args&&... args)
    {
        return (obj.*Func)(std::forward<Args>(args)...);
    }
};

int (*func)(A&) = &member_function<decltype(&A::f)>::adapter<&A::f>;

Note that in order to call the member function, an instance of A must be provided.

In 2008 we cant use Skip().Take()

The way is:

var MinPageRank = (PageNumber - 1) * NumInPage + 1
var MaxPageRank = PageNumber * NumInPage

var visit = Visita.FromSql($"SELECT * FROM (SELECT [RANK] = ROW_NUMBER() OVER (ORDER BY Hora DESC),* FROM Visita WHERE ) A WHERE A.[RANK] BETWEEN {MinPageRank} AND {MaxPageRank}").ToList();

Before defining abstract data types, let us considers the different view of system-defined data types. We all know that by default all primitive data types (int, float, etc.) support basic operations such as addition and subtraction. The system provides the implementations for the primitive data types. For user-defined data types, we also need to define operations. The implementation for these operations can be done when we want to actually use them. That means in general, user-defined data types are defined along with their operations.

To simplify the process of solving problems, we combine the data structures with their operations and we call this "Abstract Data Type". (ADT's).

Commonly used ADT'S include: Linked List, Stacks, Queues, Binary Tree, Dictionaries, Disjoint Sets (Union and find), Hash Tables and many others.

ADT's consist of two types:

1. Declaration of data.

2. Declaration of operation.

This will only work for int-digits 0-9, but your question seems to suggest that might be enough.

It works by adding the ASCII value of char '0' to the integer digit.

int i=6;
char c = '0'+i;  // now c is '6'

For example:

'0'+0 = '0'
'0'+1 = '1'
'0'+2 = '2'
'0'+3 = '3'

Edit

It is unclear what you mean, "work for alphabets"? If you want the 5th letter of the alphabet:

int i=5;
char c = 'A'-1 + i; // c is now 'E', the 5th letter.

Note that because in C/Ascii, A is considered the 0th letter of the alphabet, I do a minus-1 to compensate for the normally understood meaning of 5th letter.

Adjust as appropriate for your specific situation.
(and test-test-test! any code you write)

public class CheckHeapSize {

    public static void main(String[] args) {
        // TODO Auto-generated method stub
        long heapSize = Runtime.getRuntime().totalMemory(); 

        // Get maximum size of heap in bytes. The heap cannot grow beyond this size.// Any attempt will result in an OutOfMemoryException.
        long heapMaxSize = Runtime.getRuntime().maxMemory();

         // Get amount of free memory within the heap in bytes. This size will increase // after garbage collection and decrease as new objects are created.
        long heapFreeSize = Runtime.getRuntime().freeMemory(); 

        System.out.println("heapsize"+formatSize(heapSize));
        System.out.println("heapmaxsize"+formatSize(heapMaxSize));
        System.out.println("heapFreesize"+formatSize(heapFreeSize));

    }
    public static String formatSize(long v) {
        if (v < 1024) return v + " B";
        int z = (63 - Long.numberOfLeadingZeros(v)) / 10;
        return String.format("%.1f %sB", (double)v / (1L << (z*10)), " KMGTPE".charAt(z));
    }
}

Here's a more flexible way.

let's say this is your form.

<form>
<input type='checkbox' name='user_ids[]' value='1'id='checkbox_1' />
<input type='checkbox' name='user_ids[]' value='2'id='checkbox_2' />
<input type='checkbox' name='user_ids[]' value='3'id='checkbox_3' />
<input name="confirm" type="button" value="confirm" onclick="submit_form();" />
</form>

And this is your jquery ajax below...

                // Don't get confused at this portion right here
                // cuz "var data" will get all the values that the form
                // has submitted in the $_POST. It doesn't matter if you 
                // try to pass a text or password or select form element.
                // Remember that the "form" is not a name attribute
                // of the form, but the "form element" itself that submitted
                // the current post method
                var data = $("form").serialize(); 

                $.ajax({
                    url: "link/of/your/ajax.php", // link of your "whatever" php
                    type: "POST",
                    async: true,
                    cache: false,
                    data: data, // all data will be passed here
                    success: function(data){ 
                        alert(data) // The data that is echoed from the ajax.php
                    }
                });

And in your ajax.php, you try echoing or print_r your post to see what's happening inside it. This should look like this. Only checkboxes that you checked will be returned. If you didn't checked any, it will return an error.

<?php 
    print_r($_POST); // this will be echoed back to you upon success.
    echo "This one too, will be echoed back to you";

Hope that is clear enough.

You could achieve this quite easily with jQuery by registering for the click event of the anchors (with class="movie") and using the .load() method to send an AJAX request and replace the contents of the summary div:

$(function() {
    $('.movie').click(function() {
        $('#summary').load(this.href);

        // it's important to return false from the click
        // handler in order to cancel the default action
        // of the link which is to redirect to the url and
        // execute the AJAX request
        return false;
    });
});

#include <sstream>
#include <string>
const int i = 3;
std::ostringstream s;
s << i;
const std::string i_as_string(s.str());

[HttpPost] // it use when you write logic on button click event

public ActionResult DemoInsert(EmployeeModel emp)
{
    Employee emptbl = new Employee();    // make object of table
    emptbl.EmpName = emp.EmpName;
    emptbl.EmpAddress = emp.EmpAddress;  // add if any field you want insert
    dbc.Employees.Add(emptbl);           // pass the table object 
    dbc.SaveChanges();

    return View();
}

Perhaps it is late for the party. But there is an alternative solution for this is to use ApiMultipartFormFormatter plugin.

This plugin helps you to receive the multipart/formdata content as ASP.NET Core does.

In the github page, demo is already provided.

In Java8 you can use streams I suppose. List of Character objects:

List<Character> chars = str.chars()
    .mapToObj(e->(char)e).collect(Collectors.toList());

And set could be obtained in a similar way:

Set<Character> charsSet = str.chars()
    .mapToObj(e->(char)e).collect(Collectors.toSet());

Did you update the project (right-click on the project, "Maven" > "Update project...")? Otherwise, you need to check if pom.xml contains the necessary slf4j dependencies, e.g.:

    <dependency>
        <groupId>org.slf4j</groupId>

The easiest way to do this is just: You will receive a float or double and want it to convert it to the closest round up then just do System.out.println((int)Math.ceil(yourfloat)); it'll work perfectly

Use this code:

internal void SomeFunction() {
    Dictionary<string, string> formField = new Dictionary<string, string>();
    
    formField.Add("Name", "Henry");
    formField.Add("Age", "21");
    
    string body = GetBodyStringFromDictionary(formField);
    // output : Name=Henry&Age=21
}

internal string GetBodyStringFromDictionary(Dictionary<string, string> formField)
{
    string body = string.Empty;
    foreach (var pair in formField)
    {
        body += $"{pair.Key}={pair.Value}&";   
    }

    // delete last "&"
    body = body.Substring(0, body.Length - 1);

    return body;
}

You have it reversed. The 100 should be the first parameter (it's the key) and the "one" should be the second parameter (it's the value).

Read the javadoc for HashMap and that might help you: HashMap

To get the value, use hashmap.get(100).

EDIT:

See @Simba Answer for valid solution

submodule.<name>.update is what you want to change, see the docs - default checkout
submodule.<name>.branch specify remote branch to be tracked - default master

OLD ANSWER:

Personally I hate answers here which direct to external links which may stop working over time and check my answer here (Unless question is duplicate) - directing to question which does cover subject between the lines of other subject, but overall equals: "I'm not answering, read the documentation."

So back to the question: Why does it happen?

Situation you described

After pulling changes from server, many times my submodule head gets detached from master branch.

This is a common case when one does not use submodules too often or has just started with submodules. I believe that I am correct in stating, that we all have been there at some point where our submodule's HEAD gets detached.

• Cause: Your submodule is not tracking correct branch (default master).
  Solution: Make sure your submodule is tracking the correct branch

$ cd <submodule-path>
# if the master branch already exists locally:
# (From git docs - branch)
# -u <upstream>
# --set-upstream-to=<upstream>
#    Set up <branchname>'s tracking information so <upstream>
#    is considered <branchname>'s upstream branch.
#    If no <branchname> is specified, then it defaults to the current branch.
$ git branch -u <origin>/<branch> <branch>
# else:
$ git checkout -b <branch> --track <origin>/<branch>

• Cause: Your parent repo is not configured to track submodules branch.
  Solution: Make your submodule track its remote branch by adding new submodules with the following two commands.
  • First you tell git to track your remote <branch>.
  • you tell git to perform rebase or merge instead of checkout
  • you tell git to update your submodule from remote.

    $ git submodule add -b <branch> <repository> [<submodule-path>]
    $ git config -f .gitmodules submodule.<submodule-path>.update rebase
    $ git submodule update --remote

• If you haven't added your existing submodule like this you can easily fix that:
  • First you want to make sure that your submodule has the branch checked out which you want to be tracked.

    $ cd <submodule-path>
    $ git checkout <branch>
    $ cd <parent-repo-path>
    # <submodule-path> is here path releative to parent repo root
    # without starting path separator
    $ git config -f .gitmodules submodule.<submodule-path>.branch <branch>
    $ git config -f .gitmodules submodule.<submodule-path>.update <rebase|merge>

In the common cases, you already have fixed by now your DETACHED HEAD since it was related to one of the configuration issues above.

fixing DETACHED HEAD when .update = checkout

$ cd <submodule-path> # and make modification to your submodule
$ git add .
$ git commit -m"Your modification" # Let's say you forgot to push it to remote.
$ cd <parent-repo-path>
$ git status # you will get
Your branch is up-to-date with '<origin>/<branch>'.
Changes not staged for commit:
    modified:   path/to/submodule (new commits)
# As normally you would commit new commit hash to your parent repo
$ git add -A
$ git commit -m"Updated submodule"
$ git push <origin> <branch>.
$ git status
Your branch is up-to-date with '<origin>/<branch>'.
nothing to commit, working directory clean
# If you now update your submodule
$ git submodule update --remote
Submodule path 'path/to/submodule': checked out 'commit-hash'
$ git status # will show again that (submodule has new commits)
$ cd <submodule-path>
$ git status
HEAD detached at <hash>
# as you see you are DETACHED and you are lucky if you found out now
# since at this point you just asked git to update your submodule
# from remote master which is 1 commit behind your local branch
# since you did not push you submodule chage commit to remote. 
# Here you can fix it simply by. (in submodules path)
$ git checkout <branch>
$ git push <origin>/<branch>
# which will fix the states for both submodule and parent since 
# you told already parent repo which is the submodules commit hash 
# to track so you don't see it anymore as untracked.

But if you managed to make some changes locally already for submodule and commited, pushed these to remote then when you executed 'git checkout ', Git notifies you:

$ git checkout <branch>
Warning: you are leaving 1 commit behind, not connected to any of your branches:
If you want to keep it by creating a new branch, this may be a good time to do so with:

The recommended option to create a temporary branch can be good, and then you can just merge these branches etc. However I personally would use just git cherry-pick <hash> in this case.

$ git cherry-pick <hash> # hash which git showed you related to DETACHED HEAD
# if you get 'error: could not apply...' run mergetool and fix conflicts
$ git mergetool
$ git status # since your modifications are staged just remove untracked junk files
$ rm -rf <untracked junk file(s)>
$ git commit # without arguments
# which should open for you commit message from DETACHED HEAD
# just save it or modify the message.
$ git push <origin> <branch>
$ cd <parent-repo-path>
$ git add -A # or just the unstaged submodule
$ git commit -m"Updated <submodule>"
$ git push <origin> <branch>

Although there are some more cases you can get your submodules into DETACHED HEAD state, I hope that you understand now a bit more how to debug your particular case.

You also can use some HTML5 attributes, some browsers might already take advantage of them (type="number" min="0").

Whatever you do, remember to re-check your inputs on the server side: you can never assume the client-side validation has been performed.

Given

    volumes:
      - /dir/on/host:/var/www/html

if /dir/on/host doesn't exist, it is created on the host and the empty content is mounted in the container at /var/www/html. Whatever content you had before in /var/www/html inside the container is inaccessible, until you unmount the volume; the new mount is hiding the old content.

A simple example to calculate the memory usage of a block of codes / function using memory_profile, while returning result of the function:

import memory_profiler as mp

def fun(n):
    tmp = []
    for i in range(n):
        tmp.extend(list(range(i*i)))
    return "XXXXX"

calculate memory usage before running the code then calculate max usage during the code:

start_mem = mp.memory_usage(max_usage=True)
res = mp.memory_usage(proc=(fun, [100]), max_usage=True, retval=True) 
print('start mem', start_mem)
print('max mem', res[0][0])
print('used mem', res[0][0]-start_mem)
print('fun output', res[1])

calculate usage in sampling points while running function:

res = mp.memory_usage((fun, [100]), interval=.001, retval=True)
print('min mem', min(res[0]))
print('max mem', max(res[0]))
print('used mem', max(res[0])-min(res[0]))
print('fun output', res[1])

The only easy solution that I have applied is to recreate the primary condition that do the highlights as an IF condition and use it on the IF formula. Something like this. Depending on the highlight condition the formula will change but I think that should be recreated (es. highlight greater than 20).

=IF(B3>20,(B3)," ")

You can also use references on foreach values:

foreach($array as $elementKey => &$element) {
    // $element is the same than &$array[$elementKey]
    if (isset($element['id']) and $element['id'] == 'searched_value') {
        unset($element);
    }
}

The exceptions versus returning error code argument should be about flow control not philosophy (how "exceptional" an error is):

void f1() throws ExceptionType1, ExceptionType2 {}

void catchFunction() {
  try{
    while(someCondition){
      try{
        f1(); 
      }catch(ExceptionType2 e2){
        //do something, don't break the loop
      }
    }
  }catch(ExceptionType1 e1){
    //break the loop, do something else
  }

}

I tried to make to do the normalization a bit faster:

    en, _ = glyphSmart(data)

    func glyphSmart(text string) (int, int) {
        gc := 0
        dummy := 0
        for ind, _ := range text {
            gc++
            dummy = ind
        }
        dummy = 0
        return gc, dummy
    }

You can implement a middleware which handles Basic authentication.

public async Task Invoke(HttpContext context)
{
    var authHeader = context.Request.Headers.Get("Authorization");
    if (authHeader != null && authHeader.StartsWith("basic", StringComparison.OrdinalIgnoreCase))
    {
        var token = authHeader.Substring("Basic ".Length).Trim();
        System.Console.WriteLine(token);
        var credentialstring = Encoding.UTF8.GetString(Convert.FromBase64String(token));
        var credentials = credentialstring.Split(':');
        if(credentials[0] == "admin" && credentials[1] == "admin")
        {
            var claims = new[] { new Claim("name", credentials[0]), new Claim(ClaimTypes.Role, "Admin") };
            var identity = new ClaimsIdentity(claims, "Basic");
            context.User = new ClaimsPrincipal(identity);
        }
    }
    else
    {
        context.Response.StatusCode = 401;
        context.Response.Headers.Set("WWW-Authenticate", "Basic realm=\"dotnetthoughts.net\"");
    }
    await _next(context);
}

This code is written in a beta version of asp.net core. Hope it helps.

If you want to get

localhost:2806 

from

http://localhost:2806/Pages/ 

then use:

HttpContext.Current.Request.Url.Authority

I would also try it this way

1) Create the Java Beans from the JSON schema

2) Use JSON parser libraries to avoid any sort of exception

3) Cast the parse result to the Java object that was created from the initial JSON schema.

Below is an example JSON Schema"

  "USD" : {"15m" : 478.68, "last" : 478.68, "buy" : 478.55, "sell" : 478.68,  "symbol" : "$"},
  "JPY" : {"15m" : 51033.99, "last" : 51033.99, "buy" : 51020.13, "sell" : 51033.99,  "symbol" : "¥"},

If you want to include some options besides regional localization, you have to use $.extend, like this:

$(function() {
   $('#Date').datepicker($.extend({
      showMonthAfterYear: false,
      dateFormat:'d MM, y'
    },
    $.datepicker.regional['fr']
  ));
});

null is a legal value (and reserved word) in JSON, but some environments do not have a "NULL" object (as opposed to a NULL value) and hence cannot accurately represent the JSON null. So they will sometimes represent it as an empty array.

Whether null is a legal value in that particular element of that particular API is entirely up to the API designer.

To upgrade Ruby with rbenv: Per the rbenv README

• Update first: brew upgrade rbenv ruby-build
• See list of Ruby versions: versions available: rbenv install -l
• Install: rbenv install <selected version>

There are several problems here:

• Your assignment is the wrong way round; you're trying to assign a value to DateTime.Now instead of Start
• DateTime.Now is a value of type DateTime, not Integer, so the assignment wouldn't work anyway
• There's no need to have the Start variable anyway; it's doing no good
• total.Text is a property of type String - not DateTime or Integer

(Some of these would only show up at execution time unless you have Option Strict on, which you really should.)

You should use:

total.Text = DateTime.Now.ToString()

... possibly specifying a culture and/or format specifier if you want the result in a particular format.

This is likely when you have a PRIMARY KEY field and you are inserting a value that is duplicating or you have the INSERT_IDENTITY flag set to on

I had similar problem. I r?n npm cache clear, closed android SDK manager(which was open before) and re-ran npm install -g cordova and that was enough to solve the problem.

It work for me at code first. It return a list with matching property of view model(StudentChapterCompletionViewModel)

var studentIdParameter = new SqlParameter
{
     ParameterName = "studentId",
     Direction = ParameterDirection.Input,
     SqlDbType = SqlDbType.BigInt,
     Value = studentId
 };

 var results = Context.Database.SqlQuery<StudentChapterCompletionViewModel>(
                "exec dbo.sp_StudentComplettion @studentId",
                 studentIdParameter
                ).ToList();

Updated for Context

Context is the instance of the class that Inherit DbContext like below.

public class ApplicationDbContext : DbContext
{
    public DbSet<City> City { get; set; }
}

var Context = new  ApplicationDbContext();

If you already got jQuery but still get this error, check you include jQuery before the js that uses it, specially if you use @RenderBody() in ASP.NET C#

You have to include jQuery before the @RenderBody() if you include the js inside the view that @RenderBody() calls.

Match the identifier name at both places

This error occurs when the identifier name of the Tablecell is different in the Swift file and in the Storyboard.

For example, the identifier is placecellIdentifier in my case.

1) The Swift File

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {

    let cell = tableView.dequeueReusableCell(withIdentifier: "placecellIdentifier", for: indexPath)
    
    // Your code 

    return cell
}

###2) The Storyboard

You have a parent element, you want to get all child of specific attribute 1. get the parent 2. get the parent nodename by using parent.nodeName.toLowerCase() convert the nodename to lower case e.g DIV will be div 3. for further specific purpose, get an attribute of the parent e.g parent.getAttribute("id"). this will give you id of the parent 4. Then use document.QuerySelectorAll(paret.nodeName.toLowerCase()+"#"_parent.getAttribute("id")+" input " ); if you want input children of the parent node

let parent = document.querySelector("div.classnameofthediv")_x000D_
let parent_node = parent.nodeName.toLowerCase()_x000D_
let parent_clas_arr = parent.getAttribute("class").split(" ");_x000D_
let parent_clas_str = '';_x000D_
  parent_clas_arr.forEach(e=>{_x000D_
     parent_clas_str +=e+'.';_x000D_
  })_x000D_
let parent_class_name = parent_clas_str.substr(0, parent_clas_str.length-1)  //remove the last dot_x000D_
let allchild = document.querySelectorAll(parent_node+"."+parent_class_name+" input")

This is actually really easy:

• Go to the "Network & Security" -> Security Group settings in the left hand navigation
• Find the Security Group that your instance is apart of
• Click on Inbound Rules
• Use the drop down and add HTTP (port 80)
• Click Apply and enjoy

in menu bar click on Edit->preference->advance at bottom click the check box true that is for Show develop menu in menu bar now a develop menu is display at menu bar where you can see all develop option and inspect.

You should not use bash in this case to get rid of the output. Yum does have an option -q which suppresses the output.

You'll most certainly also want to use -y

echo "Installing nano..."
yum -y -q install nano

To see all the options for yum, use man yum.

Updated answer

When I originally answered this question in 2014, there was no requirement to not scale the image up in the case of a small image. (The question was edited in 2015.) If you have such a requirement, you will indeed need to compare the image's size to that of the imageView and use either UIViewContentModeCenter (in the case of an image smaller than the imageView) or UIViewContentModeScaleAspectFit in all other cases.

Original answer

Setting the imageView's contentMode to UIViewContentModeScaleAspectFit was enough for me. It seems to center the images as well. I'm not sure why others are using logic based on the image. See also this question: iOS aspect fit and center

Use replace method of string like the following way:

String x="\"abcd";
String z=x.replace("\"", "");
System.out.println(z);

The separation between .h and .cpp files is mostly arbitrary at this point, a vestige of compiler optimizations long past. To my eye, declarations belong in the header and definitions belong in the implementation file. But, that's just habit, not religion.

Was following one of training with Spring webmvc 4.2.3, while I'm using Spring webmvc 5.2.3 they suggested to create a form

<form:form modelAttribute="aNewAccount" method="get" action="/accountCreated">

that was causing the "disclose" error.

Altered as below to make it work. Looks like method above was the culprit.

<form:form modelAttribute="aNewAccount" action="accountCreated.html">

in fact, exploring further, method="post" in form annotation would work if properly declared:

@RequestMapping(value="/accountCreated", method=RequestMethod.POST)

As you can see from the error message the paths, that you specified, are wrong. Try it like this:

activate ..\..\temp\venv\test

However, when I needed to install Anaconda, I downloaded it from here and installed it to the default paths (C:\Anaconda), than I put this path to the environment variables, so now Anacondas interpreter is used as default. If you are using PyCharm, for example, you can specify the interpreter there directly.

If it's XHTML, your example is, you need only simpleXML.

<?php
$input = '<img src="/image/fluffybunny.jpg" title="Harvey the bunny" alt="a cute little fluffy bunny"/>';
$sx = simplexml_load_string($input);
var_dump($sx);
?>

Output:

object(SimpleXMLElement)#1 (1) {
  ["@attributes"]=>
  array(3) {
    ["src"]=>
    string(22) "/image/fluffybunny.jpg"
    ["title"]=>
    string(16) "Harvey the bunny"
    ["alt"]=>
    string(26) "a cute little fluffy bunny"
  }
}

There is no workaround. You can only ad hoc deploy apps if they are registered with your device. This prevents you from building your own app store..

For me it was a load balancer/url issue. A web service behind a load balancer called another service behind the same load balancer using the full url like: loadbalancer.mycompany.com. I changed it to bypass the load balancer when calling the second service by using localhost.mycompany.com instead.

I think there was some kind of circular reference issue going on with the load balancer.

Use npm scripts instead... Edit your package.json and add the command to script section.

Then just execute npm start

To check a number is positive, negative or negative zero. Check its sign using Math.sign() method it will provide you -1,-0,0 and 1 on the basis of positive negative and negative zero or zero numbers

 Math.sign(-3) // -1
 Math.sign(3) // 1
 Math.sign(-0) // -0
 Math.sign(0) // 0

It is not necessary to have two routes.

Simply add (/*)? at the end of your path string.

For example, app.get('/hello/world(/*)?' /* ... */)

Here is a fully working example, feel free to copy and paste this into a .js file to run with node, and play with it in a browser (or curl):

const app = require('express')()

// will be able to match all of the following
const test1 = 'http://localhost:3000/hello/world'
const test2 = 'http://localhost:3000/hello/world/'
const test3 = 'http://localhost:3000/hello/world/with/more/stuff'

// but fail at this one
const failTest = 'http://localhost:3000/foo/world'

app.get('/hello/world(/*)?', (req, res) => res.send(`
    This will match at example endpoints: <br><br>
    <pre><a href="${test1}">${test1}</a></pre>
    <pre><a href="${test2}">${test2}</a></pre>
    <pre><a href="${test3}">${test3}</a></pre>

    <br><br> Will NOT match at: <pre><a href="${failTest}">${failTest}</a></pre>
`))

app.listen(3000, () => console.log('Check this out in a browser at http://localhost:3000/hello/world!'))

Try to use <> instead of !=.

The below code in file "Locomotive.java" will compile and run successfully, with the execution results showing

2<SPACE>

As mentioned in above post, the overload rules still work for the main method. However, the entry point is the famous psvm (public static void main(String[] args))

public class Locomotive {
    Locomotive() { main("hi");}

    public static void main(String[] args) {
        System.out.print("2 ");
    }

    public static void main(String args) {
        System.out.print("3 " + args);
    }
}

This can be massively simplified with just 1 line of code in viewDidAppear:

    override func viewDidAppear(animated: Bool) {
        super.viewDidAppear(animated)

        tableViewHeightConstraint.constant = tableView.contentSize.height
    }

The modern way to do this is with flexbox, adding align-items: flex-end; on the container.

With this content:

<div class="Container">
  <div>one</div>
  <div>two</div>
</div>

Use this style:

.Container {
  display: flex;
  align-items: flex-end;
}

header('Location: '.$_SERVER['PHP_SELF']);  

will also work

As per latest Ansible Version 2.5, to check if a variable is defined and depending upon this if you want to run any task, use undefined keyword.

tasks:
    - shell: echo "I've got '{{ foo }}' and am not afraid to use it!"
      when: foo is defined

    - fail: msg="Bailing out. this play requires 'bar'"
      when: bar is undefined

IMHO, the most convenient way is to follow "Import CSV data into postgresql, the comfortable way ;-)", using csvsql from csvkit, which is a python package installable via pip.

In Web, simply add the url you want to open:

{  
  "condition": "'test-topic' in topics || 'test-topic-2' in topics",  
  "notification": {
            "title": "FCM Message with condition and link",
            "body": "This is a Firebase Cloud Messaging Topic Message!",            
            "click_action": "https://yoururl.here"
        }
}

In Swift 2.0, @user478681's answer might look like this:

    let HTMLDocumentPath = NSBundle.mainBundle().pathForResource("index", ofType: "html")
    let HTMLString: NSString?

    do {
        HTMLString = try NSString(contentsOfFile: HTMLDocumentPath!, encoding: NSUTF8StringEncoding)
    } catch {
        HTMLString = nil
    }

    myWebView.loadHTMLString(HTMLString as! String, baseURL: nil)

One way to handle this is to create a new BufferedImage, and tell it's graphics object to draw your scaled image into the new BufferedImage:

final float FACTOR  = 4f;
BufferedImage img = ImageIO.read(new File("graphic.png"));
int scaleX = (int) (img.getWidth() * FACTOR);
int scaleY = (int) (img.getHeight() * FACTOR);
Image image = img.getScaledInstance(scaleX, scaleY, Image.SCALE_SMOOTH);
BufferedImage buffered = new BufferedImage(scaleX, scaleY, TYPE);
buffered.getGraphics().drawImage(image, 0, 0 , null);

That should do the trick without casting.

The inner join in your sub-query is unnecessary. It looks like you want to delete the entries in story_category where the category_id is not in the category table.

Do this:

DELETE FROM story_category 
WHERE category_id NOT IN (
    SELECT DISTINCT category.id 
    FROM category);

Instead of that:

DELETE FROM story_category 
WHERE category_id NOT IN (
    SELECT DISTINCT category.id 
    FROM category INNER JOIN
         story_category ON category_id=category.id);

You can use new Date () and it'll give you current time.

If you need to represent it in some format (and usually you need to do it) then use formatters.

DateFormat df = DateFormat.getDateTimeInstance (DateFormat.MEDIUM, DateFormat.MEDIUM, new Locale ("en", "EN"));
String formattedDate = df.format (new Date ());

Once you've found your jar through mvnrepository.com, hover the "download (JAR)" link, and you'll see the link to the repository which contains your jar (you can probably Right clic and "Copy link URL" to get the URL, what ever your browser is).

Then, you have to add this repository to the repositories used by your project, in your pom.xml :

<project>
  ...
  <repositories>
    <repository>
      <id>my-alternate-repository</id>
      <url>http://myrepo.net/repo</url>
    </repository>
  </repositories>
  ...
</project>

EDIT : now MVNrepository.com has evolved : You can find the link to the repository in the "Repositories" section :

Trying to answer specifically to the question (at least the title).

You can also rename local branch, but keeps tracking the old name on the remote.

git branch -m old_branch new_branch
git push --set-upstream origin new_branch:old_branch

Now, when you run git push, the remote old_branch ref is updated with your local new_branch.

You have to know and remember this configuration. But it can be useful if you don't have the choice for the remote branch name, but you don't like it (oh, I mean, you've got a very good reason not to like it !) and prefer a clearer name for your local branch.

Playing with the fetch configuration, you can even rename the local remote-reference. i.e, having a refs/remote/origin/new_branch ref pointer to the branch, that is in fact the old_branch on origin. However, I highly discourage this, for the safety of your mind.

In addition to Tim's answer, which is very appropriate to your specific example, it's worth mentioning collections.defaultdict, which lets you do stuff like this:

>>> d = defaultdict(int)
>>> d[0] += 1
>>> d
{0: 1}
>>> d[4] += 1
>>> d
{0: 1, 4: 1}

For mapping [1, 2, 3, 4] as in your example, it's a fish out of water. But depending on the reason you asked the question, this may end up being a more appropriate technique.

This error tells you everything:

undefined reference toHash::insert(int, char)

You're not linking with the implementations of functions defined in Hash.h. Don't you have a Hash.cpp to also compile and link?

In my case it allows me to apply a CSS stylesheet without worrying about copying associated images, since they're already embedded inside.

 Context means current. Context use to do operation for current screen. ex.
  1. getApplicationContext()
  2. getContext()

Toast.makeText(getApplicationContext(), "hello", Toast.LENGTH_SHORT).show();

I just tried doing this on Chrome:

var $sel = $('#sel'); $sel.find('option').hover(function(){$sel.attr('title',$(this).attr('title'));console.log($(this).attr('title'))}, function(){$sel.attr('title','');});

However, the hover enter never fires... So you wouldn't be able to do this at all using the standard select. You could achieve this though through some non standard ways:

• You could fake a select box by using radio boxes that look like dropdowns. So for example, have a radio box absolute positioned and opacity set to 0 placed over the styled box that is pretending to be the option.
• Or you could use pure javascript and have a series of boxes and adding javascript onclick events to recreate the dropbox yourself - so you will update a hidden value with whichever box was clicked using javascript.
• Or use one of the non standard libraries already out there. (If there are any?)

You don't need to pass this, there already is the event object passed by default automatically, which contains event.target which has the object it's coming from. You can lighten your syntax:

This:

<p onclick="doSomething()">

Will work with this:

function doSomething(){
  console.log(event);
  console.log(event.target);
}

You don't need to instantiate the event object, it's already there. Try it out. And event.target will contain the entire object calling it, which you were referencing as "this" before.

Now if you dynamically trigger doSomething() from somewhere in your code, you will notice that event is undefined. This is because it wasn't triggered from an event of clicking. So if you still want to artificially trigger the event, simply use dispatchEvent:

document.getElementById('element').dispatchEvent(new CustomEvent("click", {'bubbles': true}));

Then doSomething() will see event and event.target as per usual!

No need to pass this everywhere, and you can keep your function signatures free from wiring information and simplify things.

The max length of a varchar is subject to the max row size in MySQL, which is 64KB (not counting BLOBs):

VARCHAR(65535)

However, note that the limit is lower if you use a multi-byte character set:

VARCHAR(21844) CHARACTER SET utf8

Here are some examples:

The maximum row size is 65535, but a varchar also includes a byte or two to encode the length of a given string. So you actually can't declare a varchar of the maximum row size, even if it's the only column in the table.

mysql> CREATE TABLE foo ( v VARCHAR(65534) );
ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs

But if we try decreasing lengths, we find the greatest length that works:

mysql> CREATE TABLE foo ( v VARCHAR(65532) );
Query OK, 0 rows affected (0.01 sec)

Now if we try to use a multibyte charset at the table level, we find that it counts each character as multiple bytes. UTF8 strings don't necessarily use multiple bytes per string, but MySQL can't assume you'll restrict all your future inserts to single-byte characters.

mysql> CREATE TABLE foo ( v VARCHAR(65532) ) CHARSET=utf8;
ERROR 1074 (42000): Column length too big for column 'v' (max = 21845); use BLOB or TEXT instead

In spite of what the last error told us, InnoDB still doesn't like a length of 21845.

mysql> CREATE TABLE foo ( v VARCHAR(21845) ) CHARSET=utf8;
ERROR 1118 (42000): Row size too large. The maximum row size for the used table type, not counting BLOBs, is 65535. This includes storage overhead, check the manual. You have to change some columns to TEXT or BLOBs

This makes perfect sense, if you calculate that 21845*3 = 65535, which wouldn't have worked anyway. Whereas 21844*3 = 65532, which does work.

mysql> CREATE TABLE foo ( v VARCHAR(21844) ) CHARSET=utf8;
Query OK, 0 rows affected (0.32 sec)

If your grep -i does not work then try using tr command to convert the the output of your file to lower case and then pipe it into standard grep with whatever you are looking for. (it sounds complicated but the actual command which I have provided for you is not !).

Notice the tr command does not change the content of your original file, it just converts it just before it feeds it into grep.

1.here is how you can do this on a file

tr '[:upper:]' '[:lower:]' <your_file.txt|grep what_ever_you_are_searching_in_lower_case

2.or in your case if you are just echoing something

echo "ABC"|tr '[:upper:]' '[:lower:]' | grep abc

With Spring, you can use this:

import org.springframework.core.io.ClassPathResource;

// Don't worry when use a not existed directory or a empty directory
// It can be used in @before
String dir = new ClassPathResource(".").getFile().getAbsolutePath()+"/"+"Your Path";

This exception also will be raised whenever a function has been called with the combination of keyword arguments and args, kwargs

Example:

def function(a, b, c, *args, **kwargs):
    print(f"a: {a}, b: {b}, c: {c}, args: {args}, kwargs: {kwargs}")

function(a=1, b=2, c=3, *(4,))

And it'll raise:

<ipython-input-4-1dcb84605fe5> in <module>
----> 1 function(a=1, b=2, c=3, *(4,))

TypeError: function() got multiple values for argument 'a'

And Also it'll become more complicated, whenever you misuse it in the inheritance. so be careful we this stuff!

1- Calling a function with keyword arguments and args:

class A:
    def __init__(self, a, b, *args, **kwargs):
        self.a = a

class B(A):
    def __init__(self, *args, **kwargs):

        a = 1
        b = 2
        super(B, self).__init__(a=a, b=b, *args, **kwargs)

Your count never equals the value 100 so your loop will continue until that is true

Replace your while clause with

def gukan(count):
    while count < 100:
      print(count)
      count=count+3;
gukan(0)

and this will fix your problem, the program is executing correctly given the conditions you have given it.

This question is dated, but I had the same problem just now, the solution I found was to map a virtual directory in IIS to the networked drive with the documents, so the url became a friendly "http://" address.

Setting virtual directories:

IIS:

http://www.iis.net/configreference/system.applicationhost/sites/site/application/virtualdirectory

Apache:

Cheers!

From Ian Bicking's own introduction to pip:

pip was originally written to improve on easy_install in the following ways

• All packages are downloaded before installation. Partially-completed installation doesn’t occur as a result.
• Care is taken to present useful output on the console.
• The reasons for actions are kept track of. For instance, if a package is being installed, pip keeps track of why that package was required.
• Error messages should be useful.
• The code is relatively concise and cohesive, making it easier to use programmatically.
• Packages don’t have to be installed as egg archives, they can be installed flat (while keeping the egg metadata).
• Native support for other version control systems (Git, Mercurial and Bazaar)
• Uninstallation of packages.
• Simple to define fixed sets of requirements and reliably reproduce a set of packages.

Sending raw POST requests can be sometimes more convenient. Below you can see post.js original example from PhantomJS

// Example using HTTP POST operation

var page = require('webpage').create(),
    server = 'http://posttestserver.com/post.php?dump',
    data = 'universe=expanding&answer=42';

page.open(server, 'post', data, function (status) {
    if (status !== 'success') {
        console.log('Unable to post!');
    } else {
        console.log(page.content);
    }
    phantom.exit();
});

Compared the 3 methods

1. 2D list: 5.323603868484497 seconds
2. Numpy library : 0.3201274871826172 seconds
3. Zip (Thanks to Joran Beasley) : 0.12395167350769043 seconds

D2_list=[list(range(100))]*100
t1=time.time()
for i in range(10**5):
    for j in range(10):
        b=[k[j] for k in D2_list]
D2_list_time=time.time()-t1

array=np.array(D2_list)
t1=time.time()        
for i in range(10**5):
    for j in range(10):
        b=array[:,j]        
Numpy_time=time.time()-t1

D2_trans = list(zip(*D2_list)) 
t1=time.time()        
for i in range(10**5):
    for j in range(10):
        b=D2_trans[j]
Zip_time=time.time()-t1

print ('2D List:',D2_list_time)
print ('Numpy:',Numpy_time)
print ('Zip:',Zip_time)

The Zip method works best. It was quite useful when I had to do some column wise processes for mapreduce jobs in the cluster servers where numpy was not installed.

Test if your variable is an instance of numbers.Number:

>>> import numbers
>>> import decimal
>>> [isinstance(x, numbers.Number) for x in (0, 0.0, 0j, decimal.Decimal(0))]
[True, True, True, True]

This uses ABCs and will work for all built-in number-like classes, and also for all third-party classes if they are worth their salt (registered as subclasses of the Number ABC).

However, in many cases you shouldn't worry about checking types manually - Python is duck typed and mixing somewhat compatible types usually works, yet it will barf an error message when some operation doesn't make sense (4 - "1"), so manually checking this is rarely really needed. It's just a bonus. You can add it when finishing a module to avoid pestering others with implementation details.

This works starting with Python 2.6. On older versions you're pretty much limited to checking for a few hardcoded types.

You can make the single letter optional by adding a ? after it as:

([A-Z]{1}?)

The quantifier {1} is redundant so you can drop it.

I'd advise against a simple regular expression approach to this problem. There are too many words that are substrings of other unrelated words, and you'll probably drive yourself crazy trying to overadapt the simpler solutions already provided.

You'll want at least a naive stemming algorithm (try the Porter stemmer; there's available, free code in most languages) to process text first. Keep this processed text and the preprocessed text in two separate space-split arrays. Make sure each non-alphabetical character also gets its own index in this array. Whatever list of words you're filtering, stem them also.

The next step would be to find the array indices which match to your list of stemmed 'stop' words. Remove those from the unprocessed array, and then rejoin on spaces.

This is only slightly more complicated, but will be much more reliable an approach. If you've got any doubts on the value of a more NLP-oriented approach, you might want to do some research into clbuttic mistakes.

You need to make sure that you add forward slash before your link to socket.io:

<script src="/socket.io/socket.io.js"></script>

Then in the view/controller just do:

var socket = io.connect()

That should solve your problem.

Simple Example

var request = require('request');

//Custom Header pass
var headersOpt = {  
    "content-type": "application/json",
};
request(
        {
        method:'post',
        url:'https://www.googleapis.com/urlshortener/v1/url', 
        form: {name:'hello',age:25}, 
        headers: headersOpt,
        json: true,
    }, function (error, response, body) {  
        //Print the Response
        console.log(body);  
}); 

It should be possible changing setting the JAVA_HOME environment variable differently for specific applications.

When starting from the command line or from a batch script you can use set JAVA_HOME=C:\...\j2dskXXX to change the JAVA_HOME environment.

It is possible that you also need to change the PATH environment variable to use the correct java binary. To do this you can use set PATH=%JAVA_HOME%\bin;%PATH%.

I recently got this situation in one my project, which required to displayed a notification view whatever the controller displayed was and whatever was the type (UINavigationController, classic controller or custom view controller), when network status changed.

So I juste released my code, which is quite easy and actually based on a protocol so that it is flexible with every type of container controller. It seems to be related with the last answers, but in a much flexible way.

You can grab the code here : PPTopMostController

And got the top most controller using

UIViewController *c = [UIViewController topMostController];

Possible solution:

var tasks = dataList
    .Select(data => Task.Factory.StartNew(arg => DoThreadStuff(data), TaskContinuationOptions.LongRunning | TaskContinuationOptions.PreferFairness))
    .ToArray();

var timeout = TimeSpan.FromMinutes(1);
Task.WaitAll(tasks, timeout);

Assuming dataList is the list of items and each item needs to be processed in a separate thread.

Declarative programming is "the act of programming in languages that conform to the mental model of the developer rather than the operational model of the machine".

The difference between declarative and imperative programming is well illustrated by the problem of parsing structured data.

An imperative program would use mutually recursive functions to consume input and generate data. A declarative program would express a grammar that defines the structure of the data so that it can then be parsed.

The difference between these two approaches is that the declarative program creates a new language that is more closely mapped to the mental model of the problem than is its host language.

use this:

    Notification mBuilder =
            new NotificationCompat.Builder(this)
                    .setSmallIcon(R.drawable.ic_music)
                    .setContentTitle(songName).build();


    mBuilder.contentIntent=  PendingIntent.getActivity(this, 0,

I tried the win32com way and xlwings way but I didn't get any luck. I use PyCharm and didn't see the .WorkBook option in the autocompletion for win32com. I got the -2147352567 error when I tried to pass a workbook as variable.

Then, I found a work around using vba shell to run my Python script. Write something on the XLS file you are working with when everything is done. So that Excel knows that it's time to run the VBA macro.

But the vba Application.wait function will take up 100% cpu which is wierd. Some people said that using the windows Sleep function would fix it.

 Import xlsxwriter


 Shell "C:\xxxxx\python.exe 
 C:/Users/xxxxx/pythonscript.py"

 exitLoop = 0

wait for Python to finish its work.

  Do

  waitTime = TimeSerial(Hour(Now), Minute(Now), Second(Now) + 30)
  Application.Wait waitTime
  Set wb2 = Workbooks.Open("D:\xxxxx.xlsx", ReadOnly:=True)
  exitLoop = wb2.Worksheets("blablabla").Cells(50, 1)
  wb2.Close exitLoop

  Loop While exitLoop <> 1




  Call VbaScript

I wrote a simple script that test the speed and this is what I found out. Actually for loop was fastest in my case. That really suprised me, check out bellow (was calculating sum of squares).

from functools import reduce
import datetime


def time_it(func, numbers, *args):
    start_t = datetime.datetime.now()
    for i in range(numbers):
        func(args[0])
    print (datetime.datetime.now()-start_t)

def square_sum1(numbers):
    return reduce(lambda sum, next: sum+next**2, numbers, 0)


def square_sum2(numbers):
    a = 0
    for i in numbers:
        i = i**2
        a += i
    return a

def square_sum3(numbers):
    sqrt = lambda x: x**2
    return sum(map(sqrt, numbers))

def square_sum4(numbers):
    return(sum([int(i)**2 for i in numbers]))


time_it(square_sum1, 100000, [1, 2, 5, 3, 1, 2, 5, 3])
time_it(square_sum2, 100000, [1, 2, 5, 3, 1, 2, 5, 3])
time_it(square_sum3, 100000, [1, 2, 5, 3, 1, 2, 5, 3])
time_it(square_sum4, 100000, [1, 2, 5, 3, 1, 2, 5, 3])

You can bundle your Button(s) within a RelativeLayout even if your Parent Layout is Linear. Make Sure the outer most parent has android:layout_height attribute set to match_parent. And in that Button tag add 'android:alignParentBottom="True" '

jackson-annotations provides @JsonFormat which can handle a lot of customizations without the need to write the custom serializer.

For example, requesting a STRING shape for a field with numeric type will output the numeric value as string

public class Person {
    public String name;
    public int age;
    @JsonFormat(shape = JsonFormat.Shape.STRING)
    public int favoriteNumber;
}

will result in the desired output

{"name":"Joe","age":25,"favoriteNumber":"123"}

Setting the HOME environment variable to an appropriate value fix this issue for me.

If you are trying to call getClass() from Static method or static block the you can do the following way.

You can call getClass() on the Properties object you are loading into.

public static Properties pathProperties = null;

static { 
    pathProperties = new Properties();
    String pathPropertiesFile = "/file.xml;
    InputStream paths = pathProperties.getClass().getResourceAsStream(pathPropertiesFile);
}

In the main menu go with following steps

Window -> Show View -> Package Explorer.

As pointed out by other answers, in python they return floats probably because of historical reasons to prevent overflow problems. However, they return integers in python 3.

>>> import math
>>> type(math.floor(3.1))
<class 'int'>
>>> type(math.ceil(3.1))
<class 'int'>

You can find more information in PEP 3141.

If you have an array of numbers and you want an array of strings, you can write:

strings = ["%.2f" % number for number in numbers]

If your numbers are floats, the array would be an array with the same numbers as strings with two decimals.

>>> a = [1,2,3,4,5]
>>> min_a, max_a = min(a), max(a)
>>> a_normalized = [float(x-min_a)/(max_a-min_a) for x in a]
>>> a_normalized
[0.0, 0.25, 0.5, 0.75, 1.0]
>>> a_strings = ["%.2f" % x for x in a_normalized]
>>> a_strings
['0.00', '0.25', '0.50', '0.75', '1.00']

Notice that it also works with numpy arrays:

>>> a = numpy.array([0.0, 0.25, 0.75, 1.0])
>>> print ["%.2f" % x for x in a]
['0.00', '0.25', '0.50', '0.75', '1.00']

A similar methodology can be used if you have a multi-dimensional array:

new_array = numpy.array(["%.2f" % x for x in old_array.reshape(old_array.size)])
new_array = new_array.reshape(old_array.shape)

Example:

>>> x = numpy.array([[0,0.1,0.2],[0.3,0.4,0.5],[0.6, 0.7, 0.8]])
>>> y = numpy.array(["%.2f" % w for w in x.reshape(x.size)])
>>> y = y.reshape(x.shape)
>>> print y
[['0.00' '0.10' '0.20']
 ['0.30' '0.40' '0.50']
 ['0.60' '0.70' '0.80']]

If you check the Matplotlib example for the function you are using, you will notice they use a similar methodology: build empty matrix and fill it with strings built with the interpolation method. The relevant part of the referenced code is:

colortuple = ('y', 'b')
colors = np.empty(X.shape, dtype=str)
for y in range(ylen):
    for x in range(xlen):
        colors[x, y] = colortuple[(x + y) % len(colortuple)]

surf = ax.plot_surface(X, Y, Z, rstride=1, cstride=1, facecolors=colors,
        linewidth=0, antialiased=False)

HTML 5 with Webforms 2 provides an <input type="range"> which will make the browser generate a native slider for you. Unfortunately all browsers doesn't have support for this, however google has implemented all Webforms 2 controls with js. IIRC the js is intelligent enough to know if the browser has implemented the control, and triggers only if there is no native implementation.

From my point of view it should be considered best practice to use the browsers native controls when possible.

Some ad-hoc code:

row_format ="{:>15}" * (len(teams_list) + 1)
print(row_format.format("", *teams_list))
for team, row in zip(teams_list, data):
    print(row_format.format(team, *row))

This relies on str.format() and the Format Specification Mini-Language.

Log in as root, then run the following MySQL commands:

GRANT ALL PRIVILEGES ON *.* TO 'root'@'localhost';
FLUSH PRIVILEGES;

Better option to change also collation of varchar columns inside table also

SELECT CONCAT('ALTER TABLE `', TABLE_NAME,'` CONVERT TO CHARACTER SET utf8 COLLATE utf8_general_ci;') AS    mySQL
FROM INFORMATION_SCHEMA.TABLES
WHERE TABLE_SCHEMA= "myschema"
AND TABLE_TYPE="BASE TABLE"

Additionnaly if you have data with forein key on non utf8 column before launch the bunch script use

SET foreign_key_checks = 0;

It means global SQL will be for mySQL :

SET foreign_key_checks = 0;
ALTER TABLE `table1` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;
ALTER TABLE `table2` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;
ALTER TABLE `tableXXX` CONVERT TO CHARACTER SET utf8 COLLATE utf8_unicode_ci;
SET foreign_key_checks = 1;

But take care if according mysql documentation http://dev.mysql.com/doc/refman/5.1/en/charset-column.html,

If you use ALTER TABLE to convert a column from one character set to another, MySQL attempts to map the data values, but if the character sets are incompatible, there may be data loss. "

EDIT: Specially with column type enum, it just crash completly enums set (even if there is no special caracters) https://bugs.mysql.com/bug.php?id=26731

addition to above answers is adding focusable to avoid UI editor's warning

android:background="?attr/selectableItemBackgroundBorderless"
android:clickable="true"

You are not required to declare any jQuery variable as you installed @types/jquery.

declare var jquery:any;   // not required
declare var $ :any;   // not required

You should have access to jQuery everywhere.

The following should work:

jQuery('.title').slideToggle();

All the answers above are helpful but none solved my issue. In my production file, my STATIC_URL was https://<URL>/static and I used the same STATIC_URL in my dev settings.py file.

This causes a silent failure in django/conf/urls/static.py.

The test elif not settings.DEBUG or '://' in prefix: picks up the '//' in the URL and does not add the static URL pattern, causing no static files to be found.

It would be thoughtful if Django spit out an error message stating you can't use a http(s):// with DEBUG = True

I had to change STATIC_URL to be '/static/'

If you want to move a non-checked out branch to another commit, the easiest way is running the git branch command with -f option, which determines where the branch HEAD should be pointing to:

git branch -f

Be careful as this won't work if the branch you are trying to move is your current branch. To move a branch pointer, run the following command: git update-ref -m "reset: Reset to " refs/heads/

The git update-ref command updates the object name stored in a ref safely.

Hope, my answer helped you.The source of information is this snippet.

1. Go to Toolbar -> Settings -> Compiler
2. In the Selected compiler drop-down menu, make sure GNU GCC Compiler is selected
3. Below that, select the compiler settings tab and then the compiler flags tab underneath
4. In the list below, make sure the box for "Have g++ follow the C++11 ISO C++ language standard [-std=c++11]" is checked
5. Click OK to save

Not forgetting

.equalsIgnoreCase(String)

if you're not worried about that sort of thing...

A simpler way would be to filter your results using "grep -v".

grep -i needle -R * | grep -v node_modules

To make it short, it means that you lacked some "dependencies" for the libraries you wanted to use. Before trying to use any kind of library, first it is suggested to look up whether it needs another library in python "family". What do I mean?

Downloading "dlls" is something that I avoid. I had the same problem with another library "kivy". The problem occurred when I wanted to use Python 3.4v instead of 3.5 Everything was working correctly in 3.5 but I just wanted to use the stable version for kivy which is 3.4 as they officially "advise". So, I switched to 3.4 but then I had the very same "dll" error saying lots of things are missing. So I checked the website and learned that I needed to install extra "dependencies" from the official website of kivy, then the problem got solved.

First uninstall your application from the emulator:

adb -e uninstall your.application.package.name

Then try to install the application again.

You probably need to run the cygwin shell as Administrator. You can right click the shortcut and click run as administrator or go into the properties of the shortcut and check it in the compatability section. Just beware.... root permissions can be dangerous.

The settings file is never created automatically, you must create it yourself, whether you use embedded or "real" maven.

Create it at the following location <your home folder>/.m2/settings.xml e.g. C:\Users\YourUserName\.m2\settings.xml on Windows or /home/YourUserName/.m2/settings.xml on Linux

Here's an empty skeleton you can use:

<settings xmlns="http://maven.apache.org/SETTINGS/1.0.0"
  xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/SETTINGS/1.0.0
                      http://maven.apache.org/xsd/settings-1.0.0.xsd">
  <localRepository/>
  <interactiveMode/>
  <usePluginRegistry/>
  <offline/>
  <pluginGroups/>
  <servers/>
  <mirrors/>
  <proxies/>
  <profiles/>
  <activeProfiles/>
</settings>

If you use Eclipse to edit it, it will give you auto-completion when editing it.

And here's the Maven settings.xml Reference page

Our Tests look like this (using Maven and Spring 3.1):

@ContextConfiguration
(
  {
   "classpath:beans.xml",
   "file:src/main/webapp/WEB-INF/spring/applicationContext.xml",
   "file:src/main/webapp/WEB-INF/spring/dispatcher-data-servlet.xml",
   "file:src/main/webapp/WEB-INF/spring/dispatcher-servlet.xml"
  }
)
@RunWith(SpringJUnit4ClassRunner.class)
public class CCustomerCtrlTest

  @Resource private ApplicationContext m_oApplicationContext;
  @Autowired private RequestMappingHandlerAdapter m_oHandlerAdapter;
  @Autowired private RequestMappingHandlerMapping m_oHandlerMapping;
  private MockHttpServletRequest m_oRequest;
  private MockHttpServletResponse m_oResp;
  private CCustomerCtrl m_oCtrl;

In my case this was actually a symptom of the server, hosted on AWS, lacking an IP for the external network. It would attempt to download namespaces from springframework.org and fail to make a connection.

1. Change the following to the file /usr/local/mysql/support-files/mysql.server the follow lines:

   basedir="/usr/local/mysql"
   
   datadir="/usr/local/mysql/data"
   

   and save it.

2. In the file /etc/rc.common add the follow line at end: /usr/local/mysql/bin/mysqld_safe --user=mysql &

I don't have enough reputation to reply to @complex857 solution. It works great, but I had to add ; at the end of the Content-Disposition header. Without it the browser adds two dashes at the end of the filename (e.g. instead of "export.csv" the file gets saved as "export.csv--"). Probably it tries to sanitize \r\n at the end of the header line.

Correct line should look like this:

header('Content-Disposition: attachment;filename="'.$filename.'";');

In case when CSV has UTF-8 chars in it, you have to change the encoding to UTF-8 by changing the Content-Type line:

header('Content-Type: application/csv; charset=UTF-8');

Also, I find it more elegant to use rewind() instead of fseek():

rewind($f);

Thanks for your solution!

My remote sql server was expecting connection at a different port and not on the default 1443.

The solution was to add a "," after your sql server IP and then add your port like so 129.0.0.1,2995 (Check the " , " after server IP)

Please find the image for reference below.

This example works. Try it.

var array = [0,1,2];
for( var i = 0, ii = array.length; i < ii; i++){
  if(i === 1){
   break;
  }
}

we can create multiply strings using * in python but not in java you can use for loop in your case:

String sample="123";
for(int i=0;i<3;i++)
{
sample=+"0";
}

In Swift 5, in order to sort Dictionary by KEYS

let sortedYourArray = YOURDICTIONARY.sorted( by: { $0.0 < $1.0 })

In order to sort Dictionary by VALUES

let sortedYourArray = YOURDICTIONARY.sorted( by: { $0.1 < $1.1 })

For BSD or GNU grep you can use -B num to set how many lines before the match and -A num for the number of lines after the match.

grep -B 3 -A 2 foo README.txt

If you want the same number of lines before and after you can use -C num.

grep -C 3 foo README.txt

This will show 3 lines before and 3 lines after.

Unfortunately, the file must be locked for updates unless you're using Office 2010 and SharePoint 2010 together. This means that only one user per time can edit a file. The locking and version tracking capabilities of SharePoint are excellent, and this makes it a great tool for the type of collaboration you're talking about, but you would have to split documents into multiple files in order to extend the amount that could be edited at a time. For instance, we sometimes unmerge documents into technical, requirements, and financials sections so that the 3 experts required for the review can work concurrently. We then merge when everyone is finished.

I think TrungTN and anon's answer is okay, but MartinStettner's way of implementing the hex() function is not really simple, and too dark, considering hex << (int)mychar is already a workaround.

here is my solution to make "<<" operator easier:

#include <sstream>
#include <iomanip>

string uchar2hex(unsigned char inchar)
{
  ostringstream oss (ostringstream::out);
  oss << setw(2) << setfill('0') << hex << (int)(inchar);
  return oss.str();
}

int main()
{
  unsigned char a = 131;
  std::cout << uchar2hex(a) << std::endl;
}

It's just not worthy implementing a stream operator :-)

i know it is a controversial topic, and likely i get burned now. but here are my thoughts.

For myself i figured that it is best to avoid classes as long as possible. If i need a complex datatype I use simple struct (C/C++), dict (python), JSON (js), or similar, i.e. no constructor, no class methods, no operator overloading, no inheritance, etc. When using class, you can get carried away by OOP itself (What Design pattern, what should be private, bla bla), and loose focus on the essential stuff you wanted to code in the first place.

If your project grows big and messy, then OOP starts to make sense because some sort of helicopter-view system architecture is needed. "function vs class" also depends on the task ahead of you.

function

• purpose: process data, manipulate data, create result sets.
• when to use: always code a function if you want to do this: “y=f(x)”

struct/dict/json/etc (instead of class)

• purpose: store attr./param., maintain attr./param., reuse attr./param., use attr./param. later.
• when to use: if you deal with a set of attributes/params (preferably not mutable)
• different languages same thing: struct (C/C++), JSON (js), dict (python), etc.
• always prefer simple struct/dict/json/etc over complicated classes (keep it simple!)

class (if it is a new data type)

• a simple perspective: is a struct (C), dict (python), json (js), etc. with methods attached.
• The method should only make sense in combination with the data/param stored in the class.
• my advice: never code complex stuff inside class methods (call an external function instead)
• warning: do not misuse classes as fake namespace for functions! (this happens very often!)
• other use cases: if you want to do a lot of operator overloading then use classes (e.g. your own matrix/vector multiplication class)
• ask yourself: is it really a new “data type”? (Yes => class | No => can you avoid using a class)

array/vector/list (to store a lot of data)

• purpose: store a lot of homogeneous data of the same data type, e.g. time series
• advice#1: just use what your programming language already have. do not reinvent it
• advice#2: if you really want your “class mysupercooldatacontainer”, then overload an existing array/vector/list/etc class (e.g. “class mycontainer : public std::vector…”)

enum (enum class)

• i just mention it
• advice#1: use enum plus switch-case instead of overcomplicated OOP design patterns
• advice#2: use finite state machines

Or use awk instead:

awk '/null/ { counter++; printf("%s%s%i\n",$0, " - Line number: ", NR)} END {print "Total null count: " counter}' file
