Programs & Examples On #Backout

use below code snip

Task.WaitAll(Task.Run(async () => await service.myAsyncMethod()));

Instead of naming my invoking class, I started using the following:

private static readonly ILog log = LogManager.GetLogger(System.Reflection.MethodBase.GetCurrentMethod().DeclaringType);

In this way, I can use the same line of code in every class that uses log4net without having to remember to change code when I copy and paste. Alternatively, i could create a logging class, and have every other class inherit from my logging class.

Want HEAD detached mode?

If you wish to rollback X time to a certain commit with a DETACHED HEAD (meaning you can't mess up anything), then by all means, use the following:

(replace X with how many commits you wish to go back)

git checkout HEAD~X

I.E. to go back one commit:

git checkout HEAD~1

map.put(key, map.get(key) + 1);

should be fine. It will update the value for the existing mapping. Note that this uses auto-boxing. With the help of map.get(key) we get the value of corresponding key, then you can update with your requirement. Here I am updating to increment value by 1.

p:after {
  content: none;
}

This is a way to remove the :after and you can do the same for :before

The use operator is for giving aliases to names of classes, interfaces or other namespaces. Most use statements refer to a namespace or class that you'd like to shorten:

use My\Full\Namespace;

is equivalent to:

use My\Full\Namespace as Namespace;
// Namespace\Foo is now shorthand for My\Full\Namespace\Foo

If the use operator is used with a class or interface name, it has the following uses:

// after this, "new DifferentName();" would instantiate a My\Full\Classname
use My\Full\Classname as DifferentName;

// global class - making "new ArrayObject()" and "new \ArrayObject()" equivalent
use ArrayObject;

The use operator is not to be confused with autoloading. A class is autoloaded (negating the need for include) by registering an autoloader (e.g. with spl_autoload_register). You might want to read PSR-4 to see a suitable autoloader implementation.

It is a bug in Firefox 3.5.

Have a look.. https://bugzilla.mozilla.org/show_bug.cgi?id=279048

you can install superagent

npm install superagent --save

then for make post call to server

import request from "../../node_modules/superagent/superagent";

request
.post('http://localhost/userLogin')
.set('Content-Type', 'application/x-www-form-urlencoded')
.send({ username: "username", password: "password" })
.end(function(err, res){
console.log(res.text);
});  

maybe you are having the same problem i had, my tablet has a SD card on it, in /mnt/sdcard and the sd card external was in /mnt/extcard, you can look it on the android file manager, going to your sd card and see the path to it.

Hope it helps.

split takes regex as a parameter.| has special meaning in regex.. use \\| instead of | to escape it.

Is this what you are after?

MatchCollection matches = Regex.Matches(mystring, "-");

for complete this script , the function for draw circle ,

    function drawCircle(coordon)
    {
        var coord = coordon.split(',');

        var c = document.getElementById("myCanvas");
        var hdc = c.getContext("2d");
        hdc.beginPath();

        hdc.arc(coord[0], coord[1], coord[2], 0, 2 * Math.PI);
        hdc.stroke();
    }

Use ampersand to specify the parent selector.

SCSS syntax:

p {
    margin: 2em auto;

    > a {
        color: red;
    }

    &:before {
        content: "";
    }

    &:after {
        content: "* * *";
    }
}

First, create a folder named “menu” in the “res” folder.

<?xml version="1.0" encoding="utf-8"?>
<menu xmlns:android="http://schemas.android.com/apk/res/android" >

    <item
        android:id="@+id/search"
        android:icon="@android:drawable/ic_menu_search"
        android:title="Search"/>
    <item
        android:id="@+id/add"
        android:icon="@android:drawable/ic_menu_add"
        android:title="Add"/>
    <item
        android:id="@+id/edit"
        android:icon="@android:drawable/ic_menu_edit"
        android:title="Edit">
        <menu>
            <item
                android:id="@+id/share"
                android:icon="@android:drawable/ic_menu_share"
                android:title="Share"/>
        </menu>
    </item>

</menu>

Then, create your Activity Class:

public class PopupMenu1 extends Activity {
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.popup_menu_1);
    }

    public void onPopupButtonClick(View button) {
        PopupMenu popup = new PopupMenu(this, button);
        popup.getMenuInflater().inflate(R.menu.popup, popup.getMenu());

        popup.setOnMenuItemClickListener(new PopupMenu.OnMenuItemClickListener() {
            public boolean onMenuItemClick(MenuItem item) {
                Toast.makeText(PopupMenu1.this,
                        "Clicked popup menu item " + item.getTitle(),
                        Toast.LENGTH_SHORT).show();
                return true;
            }
        });

        popup.show();
    }
}

import java.util.Random;

The only way I found which works for me is adding an entry into the "Web Deployment Assembly"

Project webapp > Properties > Deployment Assembly
Add ...
Source : "/target/classes"
Deploy Path : "WEB-INF/classes"

I think these pictures are understandable.

Here's yet another solution, using the XOM library, that competes with my dom4j answer. (This is part of my quest to find a good dom4j replacement where XOM was suggested as one option.)

First read the XML fragment into a nu.xom.Document:

String newNode = "<node>value</node>"; // Convert this to XML
Document newNodeDocument = new Builder().build(newNode, "");

Then, get the Document and the Node under which the fragment is added. Again, for testing purposes I'll create the Document from a string:

Document originalDoc = new Builder().build("<root><given></given></root>", "");
Element givenNode = originalDoc.getRootElement().getFirstChildElement("given");

Now, adding the child node is simple, and similar as with dom4j (except that XOM doesn't let you add the original root element which already belongs to newNodeDocument):

givenNode.appendChild(newNodeDocument.getRootElement().copy());

Outputting the document yields the correct result XML (and is remarkably easy with XOM: just print the string returned by originalDoc.toXML()):

<?xml version="1.0"?>
<root><given><node>value</node></given></root>

(If you wanted to format the XML nicely (with indentations and linefeeds), use a Serializer; thanks to Peter Štibraný for pointing this out.)

So, admittedly this isn't very different from the dom4j solution. :) However, XOM may be a little nicer to work with, because the API is better documented, and because of its design philosophy that there's one canonical way for doing each thing.

Appendix: Again, here's how to convert between org.w3c.dom.Document and nu.xom.Document. Use the helper methods in XOM's DOMConverter class:

// w3c -> xom
Document xomDoc = DOMConverter.convert(w3cDoc);

// xom -> w3c
org.w3c.dom.Document w3cDoc = DOMConverter.convert(xomDoc, domImplementation);  
// You can get a DOMImplementation instance e.g. from DOMImplementationRegistry

It is probably better to create a dedicated function to create the link so you can avoid creating two anonymous functions. Thus:

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

<script>
  function getLink(id)
  {
    var link = document.createElement('a');
    link.setAttribute('href', '#');
    link.innerHTML = id;
    link.onclick = function()
    {
      onClickLink(id);
    };
    link.style.display = 'block';
    return link;
  }
  var div = document.getElementById('div');
  for (var i = 0; i < 10; i += 1)
  {
    div.appendChild(getLink(i.toString()));
  }
</script>

Although in both cases you end up with two functions, I just think it is better to wrap it in a function that is semantically easier to comprehend.

You can use query string to pass value from one page to another..

1.pass the value using querystring

 Response.Redirect("Default3.aspx?value=" + txt.Text + "& number="+n);

2.Retrive the value in the page u want by using any of these methods..

Method1:

    string v = Request.QueryString["value"];
    string n=Request.QueryString["number"];

Method2:

      NameValueCollection v = Request.QueryString;
    if (v.HasKeys())
    {
        string k = v.GetKey(0);
        string n = v.Get(0);
        if (k == "value")
        {
            lbltext.Text = n.ToString();
        }
        if (k == "value1")
        {
            lbltext.Text = "error occured";
        }
    }

NOTE:Method 2 is the fastest method.

Just to add to Jon's coding if you needed to take it a step further, and do more than just one column you can add something like

Dim copyRange2 As Range
Dim copyRange3 As Range

Set copyRange2 =src.Range("B2:B" & lastRow)
Set copyRange3 =src.Range("C2:C" & lastRow)

copyRange2.SpecialCells(xlCellTypeVisible).Copy tgt.Range("B12")
copyRange3.SpecialCells(xlCellTypeVisible).Copy tgt.Range("C12")

put these near the other codings that are the same you can easily change the Ranges as you need.

I only add this because it was helpful for me. I'd assume Jon already knows this but for those that are less experienced sometimes it's helpful to see how to change/add/modify these codings. I figured since Ruya didn't know how to manipulate the original coding it could be helpful if one ever needed to copy over only 2 visibile columns, or only 3, etc. You can use this same coding, add in extra lines that are almost the same and then the coding is copying over whatever you need.

I don't have enough reputation to reply to Jon's comment directly so I have to post as a new comment, sorry.

Angular 7 + NgBootstrap

A simple way of opening modal from main component and passing result back to it. is what I wanted. I created a step-by-step tutorial which includes creating a new project from scratch, installing ngbootstrap and creation of Modal. You can either clone it or follow the guide.

Hope this helps new to Angular.!

https://github.com/wkaczurba/modal-demo

Details:

modal-simple template (modal-simple.component.html):

<ng-template #content let-modal>
  <div class="modal-header">
    <h4 class="modal-title" id="modal-basic-title">Are you sure?</h4>
    <button type="button" class="close" aria-label="Close" (click)="modal.dismiss('Cross click')">
      <span aria-hidden="true">&times;</span>
    </button>
  </div>
  <div class="modal-body">
    <p>You have not finished reading my code. Are you sure you want to close?</p>
  </div>
  <div class="modal-footer">
    <button type="button" class="btn btn-outline-dark" (click)="modal.close('yes')">Yes</button>
    <button type="button" class="btn btn-outline-dark" (click)="modal.close('no')">No</button>
  </div>
</ng-template>

The modal-simple.component.ts:

import { Component, OnInit, ViewChild, Output, EventEmitter } from '@angular/core';
import { NgbModal } from '@ng-bootstrap/ng-bootstrap';

@Component({
  selector: 'app-modal-simple',
  templateUrl: './modal-simple.component.html',
  styleUrls: ['./modal-simple.component.css']
})
export class ModalSimpleComponent implements OnInit {
  @ViewChild('content') content;
  @Output() result : EventEmitter<string> = new EventEmitter();

  constructor(private modalService : NgbModal) { }

  open() {
    this.modalService.open(this.content, {ariaLabelledBy: 'modal-simple-title'})
      .result.then((result) => { console.log(result as string); this.result.emit(result) }, 
        (reason) => { console.log(reason as string); this.result.emit(reason) })
  }

  ngOnInit() {
  }

}

Demo of it (app.component.html) - simple way of dealing with return event:

<app-modal-simple #mymodal (result)="onModalClose($event)"></app-modal-simple>
<button (click)="mymodal.open()">Open modal</button>

<p>
Result is {{ modalCloseResult }}
</p>

app.component.ts - onModalClosed is executed once modal is closed:

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  modalCloseResult : string;
  title = 'modal-demo';

  onModalClose(reason : string) {
    this.modalCloseResult = reason;
  }    
}

Cheers

Followed by DeyaEldeen's answer.
In my case. I grow the textview height automatically by adding

swift 3

textView.translatesAutoresizingMaskIntoConstraints = false textView.isScrollEnabled = false

The following piece of code attempts to remove duplicates from an ArrayList though this is not an optimal solution. I was asked this question during an interview to remove duplicates through recursion, and without using a second/temp arraylist:

private void RemoveDuplicate() 
{

ArrayList dataArray = new ArrayList(5);

            dataArray.Add("1");
            dataArray.Add("1");
            dataArray.Add("6");
            dataArray.Add("6");
            dataArray.Add("6");
            dataArray.Add("3");
            dataArray.Add("6");
            dataArray.Add("4");
            dataArray.Add("5");
            dataArray.Add("4");
            dataArray.Add("1");

            dataArray.Sort();

            GetDistinctArrayList(dataArray, 0);
}

private void GetDistinctArrayList(ArrayList arr, int idx)

{

            int count = 0;

            if (idx >= arr.Count) return;

            string val = arr[idx].ToString();
            foreach (String s in arr)
            {
                if (s.Equals(arr[idx]))
                {
                    count++;
                }
            }

            if (count > 1)
            {
                arr.Remove(val);
                GetDistinctArrayList(arr, idx);
            }
            else
            {
                idx += 1;
                GetDistinctArrayList(arr, idx);
            }
        }

I just used:

import java.nio.file.Path;
import java.nio.file.Paths;

...

Path workingDirectory=Paths.get(".").toAbsolutePath();

Also another thing to be careful of is whether or not it is really stored as a classic ASCII ' (ASCII 27) or Unicode 2019 (which looks similar, but not the same).

This isn't a big deal on inserts, but it can mean the world on selects and updates.
If it's the unicode value then escaping the ' in a WHERE clause (e.g where blah = 'Workers''s Comp') will return like the value you are searching for isn't there if the ' in "Worker's Comp" is actually the unicode value.

If your client application supports free-key, as well as copy and paste based input, it could be Unicode in some rows, and ASCII in others!

A simple way to confirm this is by doing some kind of open ended query that will bring back the value you are searching for, and then copy and paste that into notepad++ or some other unicode supporting editor.

The differing appearance between the ascii value and the unicode one should be obvious to the eyes, but if you lean towards the anal, it will show up as 27 (ascii) or 92 (unicode) in a hex editor.

When you want to have cross component interaction, then you need to know what are @Input , @Output , EventEmitter and Subjects.

If the relation between components is parent- child or vice versa we use @input & @output with event emitter..

@output emits an event and you need to emit using event emitter.

If it's not parent child relationship.. then you have to use subjects or through a common service.

Faster way of doing this:

WHERE interests LIKE '%sports%' OR interests LIKE '%pub%'

is this:

WHERE interests REGEXP 'sports|pub'

Found this solution here: http://forums.mysql.com/read.php?10,392332,392950#msg-392950

More about REGEXP here: http://www.tutorialspoint.com/mysql/mysql-regexps.htm

You can use below code to initialize size and set empty value to array of Strings

String[] row = new String[size];
Arrays.fill(row, "");

Try this:

SELECT *
FROM emptable 
WHERE empid IN (
    SELECT sal,row_number () ( OVER partition by sal order by sal desc) RN
    FROM emptable
    WHERE RN=2)

Why all people want to use '==' instead of simple '=' ? It is bad habit! It used only in [[ ]] expression. And in (( )) too. But you may use just = too! It work well in any case. If you use numbers, not strings use not parcing to strings and then compare like strings but compare numbers. like that

let -i i=5 # garantee that i is nubmber
test $i -eq 5 && echo "$i is equal 5" || echo "$i not equal 5"

It's match better and quicker. I'm expert in C/C++, Java, JavaScript. But if I use bash i never use '==' instead '='. Why you do so?

Try the code below to prevent the default behaviour scrolling back to the top of the page

$(document).ready(function() {   
  $('.galleryicon').live("click", function(e) {  // the (e) represent the event
    $('#mainImage').hide();     
    $('#cakebox').css('background-image', "url('ajax-loader.gif')");     
    var i = $('<img />').attr('src',this.href).load(function() {         
      $('#mainImage').attr('src', i.attr('src'));         
      $('#cakebox').css('background-image', 'none');         
      $('#mainImage').fadeIn();     
    });
  e.preventDefault(); //Prevent default click action which is causing the 
  return false;       //page to scroll back to the top
  });  
});

For more information on event.preventDefault() have a look here at the official documentation.

Here is another, in my opinion even simpler solution using a flex wrapper:

HTML:

<div class="wrapper">
  <p>Text</p>
  <div class="line"></div>
</div>

CSS:

.wrapper {
  display: flex;
  align-items: center;
}

.line {
  border-top: 1px solid grey;
  flex-grow: 1;
  margin: 0 10px;
}

IF EXISTS (SELECT * FROM sys.types WHERE is_table_type = 1 AND name = 'MyType')
    --stuff

sys.types... they aren't schema-scoped objects so won't be in sys.objects

Update, Mar 2013

You can use TYPE_ID too

I'd like expand on @JustAGuy's answer. The method I prefer is to use AWS CLI to create a config file. The reason is, with the config file, the CLI or the SDK will automatically look for credentials in the ~/.aws folder. And the good thing is that AWS CLI is written in python.

You can get cli from pypi if you don't have it already. Here are the steps to get cli set up from terminal

$> pip install awscli  #can add user flag 
$> aws configure
AWS Access Key ID [****************ABCD]:[enter your key here]
AWS Secret Access Key [****************xyz]:[enter your secret key here]
Default region name [us-west-2]:[enter your region here]
Default output format [None]:

After this you can access boto and any of the api without having to specify keys (unless you want to use a different credentials).

You have basically two options for this. DateTime.Parse() and DateTime.ParseExact().

The first is very forgiving in terms of syntax and will parse dates in many different formats. It is good for user input which may come in different formats.

ParseExact will allow you to specify the exact format of your date string to use for parsing. It is good to use this if your string is always in the same format. This way, you can easily detect any deviations from the expected data.

You can parse user input like this:

DateTime enteredDate = DateTime.Parse(enteredString);

If you have a specific format for the string, you should use the other method:

DateTime loadedDate = DateTime.ParseExact(loadedString, "d", null);

"d" stands for the short date pattern (see MSDN for more info) and null specifies that the current culture should be used for parsing the string.

You want your if check to be:

{% if not loop.last %}
    ,
{% endif %}

Note that you can also shorten the code by using If Expression:

{{ ", " if not loop.last else "" }}

If order does matter, how about:

>>> foo = 'mppmt'
>>> ''.join(sorted(set(foo), key=foo.index))
'mpt'

String url = "jdbc:mysql://127.0.0.1:3306/yourdatabase";
String user = "username";
String password = "password";

// Load the Connector/J driver
Class.forName("com.mysql.jdbc.Driver").newInstance();
// Establish connection to MySQL
Connection conn = DriverManager.getConnection(url, user, password);

The problem is that you compiled the code with java 13 (class file 57), and the java runtime is set to java 8 (class file 52).

Assuming you have the JRE 13 installed in your local system, you could change your runtime from 52 to 57. That you can do with the plugin Choose Runtime. To install it go to File/Settings/Plugins

Once installed go to Help/Find Action, type "runtime" and select the jre 13 from the dropdown menu.

If you use webpack devServer the simplest way is to set disableHostCheck, check webpack doc like this

devServer: {
    contentBase: path.join(__dirname, './dist'),
    compress: true,
    host: 'localhost',
    // host: '0.0.0.0',
    port: 8080,
    disableHostCheck: true //for ngrok
},

Since git 1.7.9 version you can also use git commit --amend --no-edit to get your result.

Note that this will not include metadata from the other commit such as the timestamp which may or may not be important to you.

if you want use VectorDrawable and ConstraintLayout

Check the mozilla documentation on window.open. The window features ("directory=...,...,height=350") etc. arguments should be a string:

window.open('/pageaddress.html','winname',"directories=0,titlebar=0,toolbar=0,location=0,status=0,menubar=0,scrollbars=no,resizable=no,width=400,height=350");

Try if that works in your browsers. Note that some of the features might be overridden by user preferences, such as "location" (see doc.)

1. You've got the right idea about how to design your resources, IMHO. I wouldn't change a thing.

2. Rather than trying to extend HTTP with more verbs, consider what your proposed verbs can be reduced to in terms of the basic HTTP methods and resources. For example, instead of an activate_login verb, you could set up resources like: /api/users/1/login/active which is a simple boolean. To activate a login, just PUT a document there that says 'true' or 1 or whatever. To deactivate, PUT a document there that is empty or says 0 or false.

Similarly, to change or set passwords, just do PUTs to /api/users/1/password.

Whenever you need to add something (like a credit) think in terms of POSTs. For example, you could do a POST to a resource like /api/users/1/credits with a body containing the number of credits to add. A PUT on the same resource could be used to overwrite the value rather than add. A POST with a negative number in the body would subtract, and so on.

3. I'd strongly advise against extending the basic HTTP status codes. If you can't find one that matches your situation exactly, pick the closest one and put the error details in the response body. Also, remember that HTTP headers are extensible; your application can define all the custom headers that you like. One application that I worked on, for example, could return a 404 Not Found under multiple circumstances. Rather than making the client parse the response body for the reason, we just added a new header, X-Status-Extended, which contained our proprietary status code extensions. So you might see a response like:

HTTP/1.1 404 Not Found    
X-Status-Extended: 404.3 More Specific Error Here

That way a HTTP client like a web browser will still know what to do with the regular 404 code, and a more sophisticated HTTP client can choose to look at the X-Status-Extended header for more specific information.

4. For authentication, I recommend using HTTP authentication if you can. But IMHO there's nothing wrong with using cookie-based authentication if that's easier for you.

Array.forEach is meant for computing stuff not waiting, and there is nothing to be gained making computations asynchronous in an event loop (webworkers add multiprocessing, if you need multi-core computation). If you want to wait for multiple tasks to end, use a counter, which you can wrap in a semaphore class.

There is a way to skip the errors inside the code and go on with the loop anyway, hope it helps:

Sub new1()

Dim wsFunc As WorksheetFunction: Set wsFunc = Application.WorksheetFunction
Dim ws As Worksheet: Set ws = Sheets(1)
Dim rngLook As Range: Set rngLook = ws.Range("A:M")

currName = "Example"
On Error Resume Next ''if error, the code will go on anyway
cellNum = wsFunc.VLookup(currName, rngLook, 13, 0)

If Err.Number <> 0 Then
''error appeared
    MsgBox "currName not found" ''optional, no need to do anything
End If

On Error GoTo 0 ''no error, coming back to default conditions

End Sub

You can import them as

import {concat, filter, orderBy} from 'lodash';

or as

import concat from 'lodash/concat';
import orderBy from 'lodash/orderBy';
import filter from 'lodash/filter';

the second one is much optimized than the first because it only loads the needed modules

then use like this

pendingArray: concat(
                    orderBy(
                        filter(payload, obj => obj.flag),
                        ['flag'],
                        ['desc'],
                    ),
                    filter(payload, obj => !obj.flag),

Here is the simplified solution:

$date = '25/05/2010';
$date = str_replace('/', '-', $date);
echo date('Y-m-d', strtotime($date));

Result:

2010-05-25

The strtotime documentation reads:

Dates in the m/d/y or d-m-y formats are disambiguated by looking at the separator between the various components: if the separator is a slash (/), then the American m/d/y is assumed; whereas if the separator is a dash (-) or a dot (.), then the European d-m-y format is assumed.

Check the internals of synchronized append method of StringBuffer and non-synchronized append method of StringBuilder.

StringBuffer:

public StringBuffer(String str) {
    super(str.length() + 16);
    append(str);
}

public synchronized StringBuffer append(Object obj) {
    super.append(String.valueOf(obj));
    return this;
}

public synchronized StringBuffer append(String str) {
    super.append(str);
    return this;
}

StringBuilder:

public StringBuilder(String str) {
    super(str.length() + 16);
    append(str);
}

public StringBuilder append(Object obj) {
    return append(String.valueOf(obj));
}

public StringBuilder append(String str) {
    super.append(str);
    return this;
}

Since append is synchronized, StringBuffer has performance overhead compared to StrinbBuilder in multi-threading scenario. As long as you are not sharing buffer among multiple threads, use StringBuilder, which is fast due to absence of synchronized in append methods.

The easiest way to block these temporarily for testing purposes is to open up the inspect page in chrome by right-clicking anywhere on the page and clicking inspect or by pressing Ctrl+Shift+j and then going to the networking tab and then reloading the page which will send all the requests your page is supposed to make including that annoying favicon.ico. You can now simply right click the favicon.ico request and click "Block request URL".

All of the above answers are for devs who control the app source code. If you are a sysadmin, who's figuring our load-balancer or proxying configuration and is annoyed by this favicon.ico shenanigans, this simple trick does a better job. This answer is for Chrome, but I think there should be a similar alternative which you would figure out for Firefox/Opera/Tor/any other browser :)

You can view the java doc examples or the example of usage of Predicate here

Basically it is used to filter rows in the resultset based on any specific criteria that you may have and return true for those rows that are meeting your criteria:

 // the age column to be between 7 and 10
    AgeFilter filter = new AgeFilter(7, 10, 3);

    // set the filter.
    resultset.beforeFirst();
    resultset.setFilter(filter);

I have just noticed that Bjarne Stroustrup labels % as the remainder operator, not the modulo operator.

I would bet that this is its formal name in the ANSI C & C++ specifications, and that abuse of terminology has crept in. Does anyone know this for a fact?

But if this is the case then C's fmodf() function (and probably others) are very misleading. they should be labelled fremf(), etc

Some may suggest using Javascript to capture the users' actions, like right-clicking the mouse or the Ctrl+C / Ctrl+V key combinations and then stopping the operation. But this is obviously not the best or simplest solution. The solution is integrated in the input field properties itself together with some event capturing using Javascript.

In order to disabled the browsers' autocomplete, simply add the attribute to the input field. It should look something like this:

<input type="text" autocomplete="off">

And if you want to deny Copy and Paste for that field, simply add the Javascript event capturing calls oncopy, onpaste, and oncut and make them return false, like so:

<input type="text" oncopy="return false;" onpaste="return false;" oncut="return false;">

The next step is using onselectstart to deny the input field's content selection from the user, but be warned: this only works for Internet Explorer. The rest of the above work great on all the major browsers: Internet Explorer, Mozilla Firefox, Apple Safari (on Windows OS, at least) and Google Chrome.

Alright, so I ended up going with the code I wrote here, on my website ^{link is dead, view on archive.org} (also available on GitHub). I can use it in the following fashion:

from filelock import FileLock

with FileLock("myfile.txt.lock"):
    print("Lock acquired.")
    with open("myfile.txt"):
        # work with the file as it is now locked

Copy the diff file to the root of your repository, and then do:

git apply yourcoworkers.diff

More information about the apply command is available on its man page.

By the way: A better way to exchange whole commits by file is the combination of the commands git format-patch on the sender and then git am on the receiver, because it also transfers the authorship info and the commit message.

If the patch application fails and if the commits the diff was generated from are actually in your repo, you can use the -3 option of apply that tries to merge in the changes.

It also works with Unix pipe as follows:

git diff d892531 815a3b5 | git apply

Communication between a browser and a webserver takes place at so many levels that is close to impossible to answer this question. HTTP plays a role, but HTTP is meaningless without TCP which is meaningless without IP which is meaningless without a physical network on which it sent. Then, there are POST vs GET requests which are similar but enough different to warrant a special dicussion. Sometimes an HTTP request needs to be authenticated, sometimes, it needs not. Mime types should be mentioned. Then, a browser sends a different request if there is a proxy. And then also encodings play a role. So, I guess, the most concise answer to this kind of question is: the browser asks the server for data and the server gives the requested data to the browser.

Use PHP's fopen

In addition to @chanafdo answer, you can use route name

when working with laravel blade

<a href="{{route('login')}}">login here</a> with parameter in route name

when go to url like URI: profile/{id} <a href="{{route('profile', ['id' => 1])}}">login here</a>

without blade

<a href="<?php echo route('login')?>">login here</a>

with parameter in route name

when go to url like URI: profile/{id} <a href="<?php echo route('profile', ['id' => 1])?>">login here</a>

As of laravel 5.2 you can use @php @endphp to create as <?php ?> in laravel blade. Using blade your personal opinion but I suggest to use it. Learn it. It has many wonderful features as template inheritance, Components & Slots,subviews etc...

Excel 2010: On the File/Info page, go to 'Related Documents' and click break links => warning will appear that all linked values will be converted to their data values => click ok => done

The document.createEvent documentation says that "The createEvent method is deprecated. Use event constructors instead."

So you should use this method instead:

var clickEvent = new MouseEvent("click", {
    "view": window,
    "bubbles": true,
    "cancelable": false
});

and fire it on an element like this:

element.dispatchEvent(clickEvent);

as shown here.

A three-liner to combine or merge two dictionaries:

dest = {}
dest.update(orig)
dest.update(extra)

This creates a new dictionary dest without modifying orig and extra.

Note: If a key has different values in orig and extra, then extra overrides orig.

Another way of doing that is:

String date = dateAndTime.substring(0, dateAndTime.indexOf(" "));

I'm not exactly certain, but I think this might be faster/use less memory than using the .split() method.

I'm certainly not a Git "expert". I have used TortoiseGit for a while, and wondered what it was talking about when it asked me if I wanted to make a "bare" repo whenever I created one. I was reading this tutorial: https://www.atlassian.com/git/tutorials/setting-up-a-repository/git-init and it addresses the issue, but I still was not quite understanding the concept. This one helped a lot: http://bitflop.com/tutorials/git-bare-vs-non-bare-repositories.html. Now, the first one makes sense too!

According to these sources, in a nutshell a "bare" repo is used on a server where you want to setup a distribution point. It's not intented for use on your local machine. You generally push commits from your local machine to a bare repo on a remote server, and you and/or others pull from that bare repo to your local machine. So your GitHub, Assembla, etc. remote storage / distribution repo is an example where a "bare" repo is created. You would make one yourself if you were setting up your own analogous "sharing center".

The problem is simple that the PHP-Mail function is not using a well configured SMTP Server.

Nowadays Email-Clients and Servers perform massive checks on the emails sending server, like Reverse-DNS-Lookups, Graylisting and whatevs. All this tests will fail with the php mail() function. If you are using a dynamic ip, its even worse.

Use the PHPMailer-Class and configure it to use smtp-auth along with a well configured, dedicated SMTP Server (either a local one, or a remote one) and your problems are gone.

Update: a better idea, set the "AppendDataBoundItems" property to true, then declare the "Choose item" declaratively. The databinding operation will add to the statically declared item.

<asp:DropDownList ID="ddl" runat="server" AppendDataBoundItems="true">
    <asp:ListItem Value="0" Text="Please choose..."></asp:ListItem>
</asp:DropDownList>

Check if you are returning a @ResponseBody or a @ResponseStatus

I had a similar problem. My Controller looked like that:

@RequestMapping(value="/user", method = RequestMethod.POST)
public String updateUser(@RequestBody User user){
    return userService.updateUser(user).getId();
}

When calling with a POST request I always got the following error:

HTTP Status 405 - Request method 'POST' not supported

After a while I figured out that the method was actually called, but because there is no @ResponseBody and no @ResponseStatus Spring MVC raises the error.

To fix this simply add a @ResponseBody

@RequestMapping(value="/user", method = RequestMethod.POST)
public @ResponseBody String updateUser(@RequestBody User user){
    return userService.updateUser(user).getId();
}

or a @ResponseStatus to your method.

@RequestMapping(value="/user", method = RequestMethod.POST)
@ResponseStatus(value=HttpStatus.OK)
public String updateUser(@RequestBody User user){
    return userService.updateUser(user).getId();
}

simply do the select:

Select * From Times
WHERE (StartDate <= @Date) AND (EndDate >= @Date) AND
((@day = 'Monday' AND (Monday = 1))
OR (@day = 'Tuesday' AND (Tuesday = 1))
OR (Wednesday = 1))

For lazy people, use mongodump, it's faster:

mongodump -d <database_name> -o <directory_backup>

And to "restore/import" it (from directory_backup/dump/):

mongorestore -d <database_name> <directory_backup>

This way, you don't need to deal with all collections individually. Just specify the database.

Note that I would recommend against using mongodump/mongorestore for big data storages. It is very slow and once you get past 10/20GB of data it can take hours to restore.

I can't answer the why part.

But if you want something dynamic then why don't you consider Collection ArrayList.

ArrrayList can be of any Object type.

And if as an compulsion you want it as an array you can use the toArray() method on it.

For example:

            ArrayList<String> al = new ArrayList<String>();
            al.add("one");
            al.add("two");
            String[] strArray = (String[]) al.toArray(new String[0]);

I hope this might help you.

find . -type f -name "*.xls" -printf "xls2csv %p %p.csv\n" | bash

bash 4 (recursive)

shopt -s globstar
for xls in /path/**/*.xls
do
  xls2csv "$xls" "${xls%.xls}.csv"
done

Yes, it is. Declare parameter as so:

@Sort varchar(50) = NULL

Now you don't even have to pass the parameter in. It will default to NULL (or whatever you choose to default to).

Add the following property:

.c{
    ...
    overflow: hidden;
}

This will force the container to respect the height of all elements within it, regardless of floating elements.
http://jsfiddle.net/gtdfY/3/

UPDATE

Recently, I was working on a project that required this trick, but needed to allow overflow to show, so instead, you can use a pseudo-element to clear your floats, effectively achieving the same effect while allowing overflow on all elements.

.c:after{
    clear: both;
    content: "";
    display: block;
}

http://jsfiddle.net/gtdfY/368/

I know this is an old question but I did it like:

<asp:RadioButtonList runat="server" ID="myrbl" RepeatDirection="Horizontal" CssClass="rbl"> 

Use this as your class:

.rbl input[type="radio"]
{
   margin-left: 10px;
   margin-right: 1px;
}

This will print the exact line of code in the specific method, which when invoked, raised the exception:

try {

    // try code
    ..
    m.invoke(testObject);
    ..

} catch (InvocationTargetException e) {

    // Answer:
    e.getCause().printStackTrace();
} catch (Exception e) {

    // generic exception handling
    e.printStackTrace();
}

Function Test {
    Param([string]$arg1, [string]$arg2)

    Write-Host $arg1
    Write-Host $arg2
}

This is a proper params declaration.

See about_Functions_Advanced_Parameters.

And it indeed works.

A JavaScript function must first be made that holds what you want to be done:

function print() { console.log("Hello World!") }

and then that function must be called in the onClick method from inside an element:

<a onClick="print()"> ... </a>

You can learn more about modal interactions directly from the Bootstrap 3 documentation found here: http://getbootstrap.com/javascript/#modals

Your modal bind is also incorrect. It should be something like this, where "myModal" = ID of element:

$('#myModal').modal(options)

In other words, if you truly want to keep what you already have, put a "#" in front GSCCModal and see if that works.

It is also not very wise to have an onClick bound to a div element; something like a button would be more suitable.

Hope this helps!

Can also use groupby() with no need to join and stack().

Some additional advice for Windows(10) users:

1. If you are using Anaconda Prompt/PowerShell for the first time, type "Anaconda" in the search field of your Windows task bar and you will see the suggested software.
2. Make sure to open the Anaconda prompt as administrator.
3. Always navigate to your user directory or the directory with your Jupyter Notebook files first before running the command. Otherwise you might end up somewhere in your system files and be confused by an unfamiliar file tree.

The correct way to open Jupyter notebook with new data limit from the Anaconda Prompt on my own Windows 10 PC is:

(base) C:\Users\mobarget\Google Drive\Jupyter Notebook>jupyter notebook --NotebookApp.iopub_data_rate_limit=1.0e10

java.math.BigInteger is an immutable class so we can not assign new object in the location of already assigned object. But you can create new object to assign new value like:

sum = sum.add(BigInteger.valueOf(i));

You can make a category of UIView and add this in .h file of category

@property (nonatomic) IBInspectable UIColor *borderColor;
@property (nonatomic) IBInspectable CGFloat borderWidth;
@property (nonatomic) IBInspectable CGFloat cornerRadius;

Now add this in .m file

@dynamic borderColor,borderWidth,cornerRadius;

and this as well in . m file

-(void)setBorderColor:(UIColor *)borderColor{
    [self.layer setBorderColor:borderColor.CGColor];
}

-(void)setBorderWidth:(CGFloat)borderWidth{
    [self.layer setBorderWidth:borderWidth];
}

-(void)setCornerRadius:(CGFloat)cornerRadius{
    [self.layer setCornerRadius:cornerRadius];
}

now you will see this in your storyboard for all UIView subclasses (UILabel, UITextField, UIImageView etc)

Thats it.. No Need to import category anywhere, just add the category's files in the project and see these properties in the storyboard.

nawk:

$ nawk 'BEGIN{print srand()}'

• Works even on old versions of Solaris and probably other UNIX systems, where '''date +%s''' isn't implemented
• Doesn't work on Linux and other distros where the posix tools have been replaced with the GNU versions (nawk -> gawk etc.)
• Pretty unintuitive but definitelly amusing :-)

Updated answer for 2019.

Regex object is thread-safe for Matching functions. Knowing that and there are some performance options or cultural / language issues, I propose this simple solution.

public static Regex _regex = new Regex(
    @"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$",
    RegexOptions.CultureInvariant | RegexOptions.Singleline);

public static bool IsValidEmailFormat(string emailInput)
{
    return _regex.IsMatch(emailInput);
}

Alternative Configuration for Regex:

public static Regex _regex = new Regex(
    @"^([a-zA-Z0-9_\-\.]+)@((\[[0-9]{1,3}\.[0-9]{1,3}\.[0-9]{1,3}\.)|(([a-zA-Z0-9\-]+\.)+))([a-zA-Z]{2,4}|[0-9]{1,3})(\]?)$",
    RegexOptions.CultureInvariant | RegexOptions.Compiled);

I find that compiled is only faster on big string matches, like book parsing for example. Simple email matching is faster just letting Regex interpret.

What does the percentage sign mean?

It's an operator in Python that can mean several things depending on the context. A lot of what follows was already mentioned (or hinted at) in the other answers but I thought it could be helpful to provide a more extensive summary.

% for Numbers: Modulo operation / Remainder / Rest

The percentage sign is an operator in Python. It's described as:

x % y       remainder of x / y

So it gives you the remainder/rest that remains if you "floor divide" x by y. Generally (at least in Python) given a number x and a divisor y:

x == y * (x // y) + (x % y)

For example if you divide 5 by 2:

>>> 5 // 2
2
>>> 5 % 2
1

>>> 2 * (5 // 2) + (5 % 2)
5

In general you use the modulo operation to test if a number divides evenly by another number, that's because multiples of a number modulo that number returns 0:

>>> 15 % 5  # 15 is 3 * 5
0

>>> 81 % 9  # 81 is 9 * 9
0

That's how it's used in your example, it cannot be a prime if it's a multiple of another number (except for itself and one), that's what this does:

if n % x == 0:
    break

If you feel that n % x == 0 isn't very descriptive you could put it in another function with a more descriptive name:

def is_multiple(number, divisor):
    return number % divisor == 0

...

if is_multiple(n, x):
    break

Instead of is_multiple it could also be named evenly_divides or something similar. That's what is tested here.

Similar to that it's often used to determine if a number is "odd" or "even":

def is_odd(number):
    return number % 2 == 1

def is_even(number):
    return number % 2 == 0

And in some cases it's also used for array/list indexing when wrap-around (cycling) behavior is wanted, then you just modulo the "index" by the "length of the array" to achieve that:

>>> l = [0, 1, 2]
>>> length = len(l)
>>> for index in range(10):
...     print(l[index % length])
0
1
2
0
1
2
0
1
2
0

Note that there is also a function for this operator in the standard library operator.mod (and the alias operator.__mod__):

>>> import operator
>>> operator.mod(5, 2)  # equivalent to 5 % 2
1

But there is also the augmented assignment %= which assigns the result back to the variable:

>>> a = 5
>>> a %= 2  # identical to: a = a % 2
>>> a
1

% for strings: printf-style String Formatting

For strings the meaning is completely different, there it's one way (in my opinion the most limited and ugly) for doing string formatting:

>>> "%s is %s." % ("this", "good") 
'this is good'

Here the % in the string represents a placeholder followed by a formatting specification. In this case I used %s which means that it expects a string. Then the string is followed by a % which indicates that the string on the left hand side will be formatted by the right hand side. In this case the first %s is replaced by the first argument this and the second %s is replaced by the second argument (good).

Note that there are much better (probably opinion-based) ways to format strings:

>>> "{} is {}.".format("this", "good")
'this is good.'

% in Jupyter/IPython: magic commands

To quote the docs:

To Jupyter users: Magics are specific to and provided by the IPython kernel. Whether magics are available on a kernel is a decision that is made by the kernel developer on a per-kernel basis. To work properly, Magics must use a syntax element which is not valid in the underlying language. For example, the IPython kernel uses the % syntax element for magics as % is not a valid unary operator in Python. While, the syntax element has meaning in other languages.

This is regularly used in Jupyter notebooks and similar:

In [1]:  a = 10
         b = 20
         %timeit a + b   # one % -> line-magic

54.6 ns ± 2.7 ns per loop (mean ± std. dev. of 7 runs, 10000000 loops each)

In [2]:  %%timeit  # two %% -> cell magic 
         a ** b

362 ns ± 8.4 ns per loop (mean ± std. dev. of 7 runs, 1000000 loops each)

The % operator on arrays (in the NumPy / Pandas ecosystem)

The % operator is still the modulo operator when applied to these arrays, but it returns an array containing the remainder of each element in the array:

>>> import numpy as np
>>> a = np.arange(10)
>>> a
array([0, 1, 2, 3, 4, 5, 6, 7, 8, 9])

>>> a % 2
array([0, 1, 0, 1, 0, 1, 0, 1, 0, 1])

Customizing the % operator for your own classes

Of course you can customize how your own classes work when the % operator is applied to them. Generally you should only use it to implement modulo operations! But that's a guideline, not a hard rule.

Just to provide a simple example that shows how it works:

class MyNumber(object):
    def __init__(self, value):
        self.value = value

    def __mod__(self, other):
        print("__mod__ called on '{!r}'".format(self))
        return self.value % other

    def __repr__(self):
        return "{self.__class__.__name__}({self.value!r})".format(self=self)

This example isn't really useful, it just prints and then delegates the operator to the stored value, but it shows that __mod__ is called when % is applied to an instance:

>>> a = MyNumber(10)
>>> a % 2
__mod__ called on 'MyNumber(10)'
0

Note that it also works for %= without explicitly needing to implement __imod__:

>>> a = MyNumber(10)
>>> a %= 2
__mod__ called on 'MyNumber(10)'

>>> a
0

However you could also implement __imod__ explicitly to overwrite the augmented assignment:

class MyNumber(object):
    def __init__(self, value):
        self.value = value

    def __mod__(self, other):
        print("__mod__ called on '{!r}'".format(self))
        return self.value % other

    def __imod__(self, other):
        print("__imod__ called on '{!r}'".format(self))
        self.value %= other
        return self

    def __repr__(self):
        return "{self.__class__.__name__}({self.value!r})".format(self=self)

Now %= is explicitly overwritten to work in-place:

>>> a = MyNumber(10)
>>> a %= 2
__imod__ called on 'MyNumber(10)'

>>> a
MyNumber(0)

Assuming that you have JAXB installed Go to the following directory C:\Program Files\jaxb\bin open command window here

> xjc -wsdl http://localhost/mywsdl/MyDWsdl.wsdl C:\Users\myname\Desktop

C:\Users\myname\Desktop is the ouput folder you can change that to your preference

http://localhost/mywsdl/MyDWsdl.wsdl is the link to the WSDL

Instead of using System.in and System.out directly, use the Console class - it allows you to display a prompt and read an entire line (thereby fixing your problem) of input in one call:

String address = System.console().readLine("Enter your Address: ");

SQL Server

SELECT 
    c.name 
FROM
    sys.objects o
INNER JOIN
    sys.columns c
ON
    c.object_id = o.object_id
AND o.name = 'Table_Name'

or

SELECT 
    COLUMN_NAME 
FROM 
    INFORMATION_SCHEMA.COLUMNS
WHERE 
    TABLE_NAME  = 'Table_Name'

The second way is an ANSI standard and therefore should work on all ANSI compliant databases.

If you don't need VML and IE8 support then use Canvas (PaperJS for example). Look at latest IE10 demos for Windows 7. They have amazing animations in Canvas. SVG is not capable to do anything close to them. Overall Canvas is available at all mobile browsers. SVG is not working at early versions of Android 2.0- 2.3 (as I know)

Yes, Canvas is not scalable, but it so fast that you can redraw the whole canvas faster then browser capable to scroll view port.

From my perspective Microsoft's optimizations provides means to use Canvas as regular GDI engine and implement graphics applications like we do them for Windows now.

If you want to treat accented latin characters (eg. à Ñ) as normal letters (ie. avoid matching them too), you'll also need to include the appropriate Unicode range (\u00C0-\u00FF) in your regex, so it would look like this:

/[^a-zA-Z\d\s:\u00C0-\u00FF]/g

• ^ negates what follows
• a-zA-Z matches upper and lower case letters
• \d matches digits
• \s matches white space (if you only want to match spaces, replace this with a space)
• : matches a colon
• \u00C0-\u00FF matches the Unicode range for accented latin characters.

nb. Unicode range matching might not work for all regex engines, but the above certainly works in Javascript (as seen in this pen on Codepen).

nb2. If you're not bothered about matching underscores, you could replace a-zA-Z\d with \w, which matches letters, digits, and underscores.

TextView tt;

also

tt.setBackgroundColor(Integer.parseInt("d4d446", 16)+0xFF000000);

also

tt.setBackgroundColor(Color.parseColor("#d4d446"));

For me the problem was that changing the value for this field didn`t work:

$('#cardNumber').val(maskNumber);

None of the solutions above worked for me so I investigated further and found:

According to DOM Level 2 Event Specification: The change event occurs when a control loses the input focus and its value has been modified since gaining focus. That means that change event is designed to fire on change by user interaction. Programmatic changes do not cause this event to be fired.

The solution was to add the trigger function and cause it to trigger change event like this:

$('#cardNumber').val(maskNumber).trigger('change');

This is a translation of Mike's Ruby version, into Common Lisp:

(defun perms (x y original-string)
  (loop with all = (list "")
        with current-array = (list "")
        for iteration from 1 to y
        do (loop with next-array = nil
                 for string in current-array
                 do (loop for c across original-string
                          for value = (concatenate 'string string (string c))
                          do (push value next-array)
                             (push value all))
                    (setf current-array (reverse next-array)))
        finally (return (nreverse (delete-if #'(lambda (el) (< (length el) x)) all)))))

And another version, slightly shorter and using more loop facility features:

(defun perms (x y original-string)
  (loop repeat y
        collect (loop for string in (or (car (last sets)) (list ""))
                      append (loop for c across original-string
                                   collect (concatenate 'string string (string c)))) into sets
        finally (return (loop for set in sets
                              append (loop for el in set when (>= (length el) x) collect el)))))

On top of PoolingHttpClientConnectionManager along with Registry<ConnectionSocketFactory> socketFactoryRegistry = RegistryBuilder.<ConnectionSocketFactory> create().register("https", sslFactory).build(); If you want an asynchronous httpclient using PoolingNHttpClientConnectionManager the code shoudl be similar to following

SSLContextBuilder builder = SSLContexts.custom();
builder.loadTrustMaterial(null, new TrustStrategy() {
    @Override
    public boolean isTrusted(X509Certificate[] chain, String authType)
            throws CertificateException {
        return true;
    }
});
SSLContext sslContext = builder.build();

                new HostnameVerifier(){
            @Override
            public boolean verify(String hostname, SSLSession session) {

Maps from JDK are not meant for storing data under duplicated keys.

• At best new value will override the previous ones.

• Worse scenario is exception (e.g when you try to collect it as a stream):

No duplicates:

Stream.of("one").collect(Collectors.toMap(x -> x, x -> x))

Ok. You will get: $2 ==> {one=one}

Duplicated stream:

Stream.of("one", "not one", "surely not one").collect(Collectors.toMap(x -> 1, x -> x))

Exception java.lang.IllegalStateException: Duplicate key 1 (attempted merging values one and not one) | at Collectors.duplicateKeyException (Collectors.java:133) | at Collectors.lambda$uniqKeysMapAccumulator$1 (Collectors.java:180) | at ReduceOps$3ReducingSink.accept (ReduceOps.java:169) | at Spliterators$ArraySpliterator.forEachRemaining (Spliterators.java:948) | at AbstractPipeline.copyInto (AbstractPipeline.java:484) | at AbstractPipeline.wrapAndCopyInto (AbstractPipeline.java:474) | at ReduceOps$ReduceOp.evaluateSequential (ReduceOps.java:913) | at AbstractPipeline.evaluate (AbstractPipeline.java:234) | at ReferencePipeline.collect (ReferencePipeline.java:578) | at (#4:1)

To deal with duplicated keys - use other package, e.g: https://google.github.io/guava/releases/19.0/api/docs/com/google/common/collect/Multimap.html

There is a lot of other implementations dealing with duplicated keys. Those are needed for web (e.g. duplicated cookie keys, Http headers can have same fields, ...)

Good luck! :)

Yes there is a difference!

The immediate effect of using innerHTML versus dangerouslySetInnerHTML is identical -- the DOM node will update with the injected HTML.

However, behind the scenes when you use dangerouslySetInnerHTML it lets React know that the HTML inside of that component is not something it cares about.

Because React uses a virtual DOM, when it goes to compare the diff against the actual DOM, it can straight up bypass checking the children of that node because it knows the HTML is coming from another source. So there's performance gains.

More importantly, if you simply use innerHTML, React has no way to know the DOM node has been modified. The next time the render function is called, React will overwrite the content that was manually injected with what it thinks the correct state of that DOM node should be.

Your solution to use componentDidUpdate to always ensure the content is in sync I believe would work but there might be a flash during each render.

After making changes to the pg_hba.conf or postgresql.conf files, the cluster needs to be reloaded to pick up the changes.

From the command line: pg_ctl reload

From within a db (as superuser): select pg_reload_conf();

From PGAdmin: right-click db name, select "Reload Configuration"

Note: the reload is not sufficient for changes like enabling archiving, changing shared_buffers, etc -- those require a cluster restart.

This is made to assign a default value, in this case the value of y, if the x variable is falsy.

The boolean operators in JavaScript can return an operand, and not always a boolean result as in other languages.

The Logical OR operator (||) returns the value of its second operand, if the first one is falsy, otherwise the value of the first operand is returned.

For example:

"foo" || "bar"; // returns "foo"
false || "bar"; // returns "bar"

Falsy values are those who coerce to false when used in boolean context, and they are 0, null, undefined, an empty string, NaN and of course false.

For reference, I had this error message and the solution was that when you specify the library you miss the 'lib' off the front and the '.so' from the end.

So, if you have a file libmyfablib.so, you need to call:

   System.loadLibrary("myfablib"); // this loads the file 'libmyfablib.so' 

Having looked in the apk, installed/uninstalled and tried all kinds of complex solutions I couldn't see the simple problem that was right in front of my face!

If you use:

if (Array[i].compareToIgnoreCase(Array[j]) < 0)

you will get:

Example  Hello  is  Sorting  This

which I think is the output you were looking for.

Like so:

import pandas as pd
df = pd.DataFrame({"pear": [1,2,3], "apple": [2,3,4], "orange": [3,4,5]})

len(df.columns)
3

There are several ways to do a cross join or cartesian product:

SELECT column_names FROM table1 CROSS JOIN table2;

SELECT column_names FROM table1, table2;

SELECT column_names FROM table1 JOIN table2;

Neglecting the on condition in the third case is what results in a cross join.

If you need special memory alignment on the object controlled by shared_ptr, you cannot rely on make_shared, but I think it's the only one good reason about not using it.

If you are not willing to try regex (which you should), you can use this:

s.replace('\n\n','\n')

Repeat this several times to make sure there is no blank line left. Or chaining the commands:

s.replace('\n\n','\n').replace('\n\n','\n')

_{Just to encourage you to use regex, here are two introductory videos that I find intuitive:
• Regular Expressions (Regex) Tutorial
• Python Tutorial: re Module}

Assuming you can arrange to have a container element you wish to fill, this appears to work, but feels a bit hackish. In essence, I just use min/max-width/height on a larger area and then scale that area back into the original dimensions.

.container {_x000D_
  width: 800px;_x000D_
  height: 300px;_x000D_
  border: 1px solid black;_x000D_

Using Java 8

MessageDigest digest = null;
try {
    digest = MessageDigest.getInstance("SHA-256");
} catch (NoSuchAlgorithmException e) {
    e.printStackTrace();
}
byte[] hash = digest.digest(text.getBytes(StandardCharsets.UTF_8));
String encoded = DatatypeConverter.printHexBinary(hash);        
System.out.println(encoded.toLowerCase());

You have to give the second argument of class type. You can also have it a little bit more tidy like below.

startActivity(Intent(this, Page2::class.java).apply {
    putExtra("extra_1", value1)
    putExtra("extra_2", value2)
    putExtra("extra_3", value3)
})

import inspect

def my_first_function():
    func_name = inspect.stack()[0][3]
    print(func_name)  # my_first_function

or:

import sys

def my_second_function():
    func_name = sys._getframe().f_code.co_name
    print(func_name)  # my_second_function

You can use any one of these polyfills:

• https://github.com/jamesallardice/Placeholders.js (doesn't support password fields)
• https://github.com/chemerisuk/better-placeholder-polyfill

These scripts will add support for the placeholder attribute in browsers that do not support it, and they do not require jQuery!

FragmentPagerAdapter: the fragment of each page the user visits will be stored in memory, although the view will be destroyed. So when the page is visible again, the view will be recreated but the fragment instance is not recreated. This can result in a significant amount of memory being used. FragmentPagerAdapter should be used when we need to store the whole fragment in memory. FragmentPagerAdapter calls detach(Fragment) on the transaction instead of remove(Fragment).

FragmentStatePagerAdapter: the fragment instance is destroyed when it is not visible to the User, except the saved state of the fragment. This results in using only a small amount of Memory and can be useful for handling larger data sets. Should be used when we have to use dynamic fragments, like fragments with widgets, as their data could be stored in the savedInstanceState.Also it won’t affect the performance even if there are large number of fragments.

For O(1) complexity of head,tail operation you should use deque however.

Following way:

from collections import deque
l = deque([1,2,3,4,5,6,7,8,9])
head, tail = l.popleft(), l

It's useful when you must iterate through all elements of the list. For example in naive merging 2 partitions in merge sort.

To get current date/time in javascript:

var date = new Date();

If you need milliseconds for easy server-side interpretation use

var value = date.getTime();

For formatting dates into a user readable string see this

Then just write to hidden field:

document.getElementById("DATE").value = value;

In case you are using Silex add the Symfony Asset as a dependency:

composer require symfony/asset

Then you may register Asset Service Provider:

$app->register(new Silex\Provider\AssetServiceProvider(), array(
    'assets.version' => 'v1',
    'assets.version_format' => '%s?version=%s',
    'assets.named_packages' => array(
        'css' => array(
            'version' => 'css2',
            'base_path' => __DIR__.'/../public_html/resources/css'
        ),
        'images' => array(
            'base_urls' => array(
                'https://img.example.com'
            )
        ),
    ),
));

Then in your Twig template file in head section:

<!DOCTYPE html>
<html>
<head>
    <meta charset="UTF-8">
    {% block head %}
    <link rel="stylesheet" href="{{ asset('style.css') }}" />
    {% endblock %}
</head>
<body>

</body>
</html>

Reinstall JDK and set system variable JAVA_HOME on your JDK. (e.g. C:\tools\jdk7)
And add JAVA_HOME variable to your PATH system variable

Type in command line

echo %JAVA_HOME%

and

java -version

To verify whether your installation was done successfully.

This problem generally occurs in Windows when your "Java Runtime Environment" registry entry is missing or mismatched with the installed JDK. The mismatch can be due to multiple JDKs.

Steps to resolve:

1. Open the Run window:

   Press windows+R

2. Open registry window:

   Type regedit and enter.

3. Go to: \HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\

4. If Java Runtime Environment is not present inside JavaSoft, then create a new Key and give the name Java Runtime Environment.

5. For Java Runtime Environment create "CurrentVersion" String Key and give appropriate version as value:

6. Create a new subkey of 1.8.

7. For 1.8 create a String Key with name JavaHome with the value of JRE home:

Updating the NodeJS https://nodejs.org/en/ Fixed My Issue.

Run npm install -g npm & npm cache clean

You want to do the check for undefined first. If you do it the other way round, it will generate an error if the array is undefined.

if (array === undefined || array.length == 0) {
    // array empty or does not exist
}

Update

This answer is getting a fair amount of attention, so I'd like to point out that my original answer, more than anything else, addressed the wrong order of the conditions being evaluated in the question. In this sense, it fails to address several scenarios, such as null values, other types of objects with a length property, etc. It is also not very idiomatic JavaScript.

The foolproof approach
Taking some inspiration from the comments, below is what I currently consider to be the foolproof way to check whether an array is empty or does not exist. It also takes into account that the variable might not refer to an array, but to some other type of object with a length property.

if (!Array.isArray(array) || !array.length) {
  // array does not exist, is not an array, or is empty
  // ? do not attempt to process array
}

To break it down:

1. Array.isArray(), unsurprisingly, checks whether its argument is an array. This weeds out values like null, undefined and anything else that is not an array.
   Note that this will also eliminate array-like objects, such as the arguments object and DOM NodeList objects. Depending on your situation, this might not be the behavior you're after.

2. The array.length condition checks whether the variable's length property evaluates to a truthy value. Because the previous condition already established that we are indeed dealing with an array, more strict comparisons like array.length != 0 or array.length !== 0 are not required here.

The pragmatic approach
In a lot of cases, the above might seem like overkill. Maybe you're using a higher order language like TypeScript that does most of the type-checking for you at compile-time, or you really don't care whether the object is actually an array, or just array-like.

In those cases, I tend to go for the following, more idiomatic JavaScript:

if (!array || !array.length) {
    // array or array.length are falsy
    // ? do not attempt to process array
}

Or, more frequently, its inverse:

if (array && array.length) {
    // array and array.length are truthy
    // ? probably OK to process array
}

With the introduction of the optional chaining operator (Elvis operator) in ECMAScript 2020, this can be shortened even further:

if (!array?.length) {
    // array or array.length are falsy
    // ? do not attempt to process array
}

Or the opposite:

if (array?.length) {
    // array and array.length are truthy
    // ? probably OK to process array
}

{{ ['foo', 'bar'|capitalize]|join }}

As you can see this works with filters and functions without needing to use set on a seperate line.

System.IO.Compression is now available as a nuget package maintained by Microsoft.

To use ZipFile you need to download System.IO.Compression.ZipFile nuget package.

Try this

 string htmlBody = "<html><body><h1>Picture</h1><br><img src=\"cid:filename\"></body></html>";
 AlternateView avHtml = AlternateView.CreateAlternateViewFromString
    (htmlBody, null, MediaTypeNames.Text.Html);

 LinkedResource inline = new LinkedResource("filename.jpg", MediaTypeNames.Image.Jpeg);
 inline.ContentId = Guid.NewGuid().ToString();
 avHtml.LinkedResources.Add(inline);

 MailMessage mail = new MailMessage();
 mail.AlternateViews.Add(avHtml);

 Attachment att = new Attachment(filePath);
 att.ContentDisposition.Inline = true;

 mail.From = from_email;
 mail.To.Add(data.email);
 mail.Subject = "Client: " + data.client_id + " Has Sent You A Screenshot";
 mail.Body = String.Format(
            "<h3>Client: " + data.client_id + " Has Sent You A Screenshot</h3>" +
            @"<img src=""cid:{0}"" />", att.ContentId);

 mail.IsBodyHtml = true;
 mail.Attachments.Add(att);

Really, what you want to do cannot be done because the protocols do not allow for this. If static IPs were universally used then you might be able to do it. They are not, so you cannot.

If you really want to identify people, have them log in.

Since they will probably be moving around to different pages on your web site, you need a way to keep track of them as they move about.

So long as they are logged in, and you are tracking their session within your site via cookies/link-parameters/beacons/whatever, you can be pretty sure that they are using the same computer during that time.

Ultimately, it is incorrect to say this tells you which computer they are using if your users are not using your own local network and do not have static IP addresses.

If what you want to do is being done with the cooperation of the users and there is only one user per cookie and they use a single web browser, just use a cookie.

The answer, in a few words

In your example, itsProblem is a local variable.

Your must use self to set and get instance variables. You can set it in the __init__ method. Then your code would be:

class Example(object):
    def __init__(self):
        self.itsProblem = "problem"


theExample = Example()
print(theExample.itsProblem)

But if you want a true class variable, then use the class name directly:

class Example(object):
    itsProblem = "problem"


theExample = Example()
print(theExample.itsProblem)
print (Example.itsProblem)

But be careful with this one, as theExample.itsProblem is automatically set to be equal to Example.itsProblem, but is not the same variable at all and can be changed independently.

Some explanations

In Python, variables can be created dynamically. Therefore, you can do the following:

class Example(object):
    pass

Example.itsProblem = "problem"

e = Example()
e.itsSecondProblem = "problem"

print Example.itsProblem == e.itsSecondProblem 

prints

True

Therefore, that's exactly what you do with the previous examples.

Indeed, in Python we use self as this, but it's a bit more than that. self is the the first argument to any object method because the first argument is always the object reference. This is automatic, whether you call it self or not.

Which means you can do:

class Example(object):
    def __init__(self):
        self.itsProblem = "problem"


theExample = Example()
print(theExample.itsProblem)

or:

class Example(object):
    def __init__(my_super_self):
        my_super_self.itsProblem = "problem"


theExample = Example()
print(theExample.itsProblem)

It's exactly the same. The first argument of ANY object method is the current object, we only call it self as a convention. And you add just a variable to this object, the same way you would do it from outside.

Now, about the class variables.

When you do:

class Example(object):
    itsProblem = "problem"


theExample = Example()
print(theExample.itsProblem)

You'll notice we first set a class variable, then we access an object (instance) variable. We never set this object variable but it works, how is that possible?

Well, Python tries to get first the object variable, but if it can't find it, will give you the class variable. Warning: the class variable is shared among instances, and the object variable is not.

As a conclusion, never use class variables to set default values to object variables. Use __init__ for that.

Eventually, you will learn that Python classes are instances and therefore objects themselves, which gives new insight to understanding the above. Come back and read this again later, once you realize that.

JQuery 1.5 introduces promises, and here's the simplest implementation I've seen to control order of execution. Full documentation at http://api.jquery.com/jquery.when/

$.when( $('#myDiv').css('background-color', 'red') )
 .then( alert('hi!') )
 .then( myClickFunction( $('#myID') ) )
 .then( myThingToRunAfterClick() );

Why use regex for that. String implements IEnumerable<char>, so you can just use LINQ.

test.Count(c => c == '&')

The same problem error happened to me when I tried to present a child view controller instead of its UINavigationViewController parent

In short, it lets you assign values to a variable in an outer (but non-global) scope. See PEP 3104 for all the gory details.

Try max(): http://php.net/manual/en/function.max.php See the first comment on that page

//javascript function calling an jquery function

//In javascript part

function js_show_score()
{
     //we use so many javascript library, So please use 'jQuery' avoid '$'  
     jQuery(function(){ 
        //Call any jquery function
        show_score(); //jquery function
    });(jQuery);  
}

//In Jquery part

jQuery(function(){ 
//Jq Score function     
    function show_score()
    {   
        $('#score').val("10");
    }
});(jQuery); 

$("#closeLink").click(closeIt);

Let's say you want to call your function passing some args to it i.e., closeIt(1, false). Then, you should build an anonymous function and call closeIt from it.

$("#closeLink").click(function() {
    closeIt(1, false);
});

This two commands work for me in my project

composer require laravel/ui --dev

Then

php artisan ui:auth

You can do:

$("#country.save")...

OR

$("a#country.save")...

OR

$("a.save#country")...

as you prefer.

So yes you can specify a selector that has to match ID and class (and potentially tag name and anything else you want to throw in).

You need to call format() function to get the formatted value

$scope.SearchDate = moment(new Date()).format("DD/MM/YYYY")
//or $scope.SearchDate = moment().format("DD/MM/YYYY")

The syntax you have used is used to parse a given string to date object by using the specified formate

You have to call close() on the GZIPOutputStream before you attempt to read it. The final bytes of the file will only be written when the file is actually closed. (This is irrespective of any explicit buffering in the output stack. The stream only knows to compress and write the last bytes when you tell it to close. A flush() probably won't help ... though calling finish() instead of close() should work. Look at the javadocs.)

Here's the correct code (in Java);

package test;

import java.io.FileInputStream;
import java.io.FileNotFoundException;
import java.io.FileOutputStream;
import java.io.IOException;
import java.util.zip.GZIPInputStream;
import java.util.zip.GZIPOutputStream;

public class GZipTest {

    public static void main(String[] args) throws
                FileNotFoundException, IOException {
        String name = "/tmp/test";
        GZIPOutputStream gz = new GZIPOutputStream(new FileOutputStream(name));
        gz.write(10);
        gz.close();       // Remove this to reproduce the reported bug
        System.out.println(new GZIPInputStream(new FileInputStream(name)).read());
    }
}

(I've not implemented resource management or exception handling / reporting properly as they are not relevant to the purpose of this code. Don't treat this as an example of "good code".)

The command ansible localhost -m setup basically says "run the setup module against localhost", and the setup module gathers the facts that you see in the output.

When you run the echo command these facts don't exist since the setup module wasn't run. A better method to testing things like this would be to use ansible-playbook to run a playbook that looks something like this:

- hosts: localhost
  tasks:
      - debug: var=ansible_date_time

      - debug: msg="the current date is {{ ansible_date_time.date }}"

Because this runs as a playbook facts for localhost are gathered before the tasks are run. The output of the above playbook will be something like this:

PLAY [localhost] **************************************************

GATHERING FACTS ***************************************************************

To get the form that the submit is inside why not just

this.form

Easiest & quickest path to the result.

I noticed the same error as soon as I added Google Analytics and started testing on localhost.

I have both AdBlock as well as Ghostery... it actually (for me) wasn't AdBlock interfering - it was Ghostery. To "fix", in Ghostery settings, under "Analytics", uncheck Google Analytics.

As a simplification to chrfin's response, since Chrome should be on the run path if installed, you could just call:

Process.Start("chrome.exe", "http://www.YourUrl.com");

This seem to work as expected for me, opening a new tab if Chrome is already open.

You can check for text in your page source as follow:

Assert.IsTrue(driver.PageSource.Contains("Your Text Here"))

If you really want to hide it, as in "not visible", then you will probably have to create a borderless form and draw the caption components yourself. VisualStyles library has the Windows Elements available. You would also have to add back in the functionality of re-sizing the form or moving the form by grabbing the caption bar. Not to mention the system menu in the corner.

In most cases, it's hard to justify having the "close" button not available, especially when you want a modal form with minimizing capabilities. Minimizing a modal form really makes no sense.

Actually, this may or may not be much help but you could write a script which created a Java class for each Python class, including method stubs, placing the Python implementation of the method inside the Javadoc

In fact, this is probably pretty easy to knock up in Python.

I worked for a company which undertook a port to Java of a huge Smalltalk (similar-ish to Python) system and this is exactly what they did. Filling in the methods was manual but invaluable, because it got you to really think about what was going on. I doubt that a brute-force method would result in nice code.

Here's another possibility: can you convert your Python to Jython more easily? Jython is just Python for the JVM. It may be possible to use a Java decompiler (e.g. JAD) to then convert the bytecode back into Java code (or you may just wish to run on a JVM). I'm not sure about this however, perhaps someone else would have a better idea.

I started with this book: Relational Database Design Clearly Explained (The Morgan Kaufmann Series in Data Management Systems) (Paperback) by Jan L. Harrington and found it very clear and helpful

and as you get up to speed this one was good too Database Systems: A Practical Approach to Design, Implementation and Management (International Computer Science Series) (Paperback)

I think SQL and database design are different (but complementary) skills.

I was experiencing a kind of similar issue:

System setup and Problem: (On a virtualbox I'm web hosting using ubuntu and nginx - PHP webpage refreshes did not reflect changes to external css file). I'm developing website on windows machine and transferring files to nginx via shared folder. It seems nginx does not pick up changes to css file (refreshing in any fashion does not help. Changing css file name is only thing that worked)

Solution: On VM find shared file (css file in my case). Open with nano and compare to file in windows share (they appear identical). On VM save shared file with nano. All changes are now reflected in browser. Not sure why this works but it did in my case.

UPDATE: After rebooting the VM server the problem returned. Following the instructions under Solution made the css responsive to updates again

Some differences between “state” and “props” in react.

React controls and renders DOM based on state. There are two types of component states: props is the state that transfers between components, and state is internal state of components. Props is used for data transfer from the parent component to the child component. The components also have their own state inside: state which can only be modified inside the component.

Generally the state of certain component could be the props of the child component ,props will be passed to children which is stated inside the rendering method of the parent component

The smallest one I know is lighttpd.

Security, speed, compliance, and flexibility -- all of these describe lighttpd (pron. lighty) which is rapidly redefining efficiency of a webserver; as it is designed and optimized for high performance environments. With a small memory footprint compared to other web-servers, effective management of the cpu-load, and advanced feature set (FastCGI, SCGI, Auth, Output-Compression, URL-Rewriting and many more) lighttpd is the perfect solution for every server that is suffering load problems. And best of all it's Open Source licensed under the revised BSD license.

Edit: removed Windows version link, now a spam/malware plugin site.

I found many times problematic behavior of this whole. I used it from express (without typings) and the bodyParser (with the dt~body-parser typings).

I didn't try to upload a file, instead simply to interpret a JSON given in a post string.

The request.body was simply an empty json ({}).

After a lot of investigation finally this worked for me:

import { json } from 'body-parser';
...
app.use(json()); <-- should be defined before the first POST handler!

It may be also important to give the application/json content type in the request string from the client side.

java.lang.NoSuchMethodError: javax.servlet.ServletContext.getContextPath()Ljava/lang/String;

That method was added in Servlet 2.5.

So this problem can have at least 3 causes:

1. The servlet container does not support Servlet 2.5.
2. The web.xml is not declared conform Servlet 2.5 or newer.
3. The webapp's runtime classpath is littered with servlet container specific JAR files of a different servlet container make/version which does not support Servlet 2.5.

To solve it,

1. Make sure that your servlet container supports at least Servlet 2.5. That are at least Tomcat 6, Glassfish 2, JBoss AS 4.1, etcetera. Tomcat 5.5 for example supports at highest Servlet 2.4. If you can't upgrade Tomcat, then you'd need to downgrade Spring to a Servlet 2.4 compatible version.
2. Make sure that the root declaration of web.xml complies Servlet 2.5 (or newer, at least the highest whatever your target runtime supports). For an example, see also somewhere halfway our servlets wiki page.
3. Make sure that you don't have any servlet container specific libraries like servlet-api.jar or j2ee.jar in /WEB-INF/lib or even worse, the JRE/lib or JRE/lib/ext. They do not belong there. This is a pretty common beginner's mistake in an attempt to circumvent compilation errors in an IDE, see also How do I import the javax.servlet API in my Eclipse project?.

When doing a clean HTML Structure, you can use this.

//Jquery Code_x000D_
$('a#link_1').click(function(e){_x000D_
  e . preventDefault () ;_x000D_
  var a = e . target ;_x000D_
  window . open ( '_top' , a . getAttribute ('href') ) ;_x000D_
});_x000D_
_x000D_
//Normal Code_x000D_
element = document . getElementById ( 'link_1' ) ;_x000D_
element . onClick = function (e) {_x000D_
  e . preventDefault () ;_x000D_
  _x000D_
  window . open ( '_top' , element . getAttribute ('href') ) ;_x000D_
} ;

<a href="#Foo" id="link_1">Do it!</a>

Use COALESCE to avoid that outcome.

SELECT COALESCE(SUM(column),0)
FROM   table
WHERE  ...

Given three tables (one with all numbers, one with all nulls, and one with a mixture):

SQL Fiddle

MySQL 5.5.32 Schema Setup:

CREATE TABLE foo
(
  id    INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
  val   INT
);

INSERT INTO foo (val) VALUES
(null),(1),(null),(2),(null),(3),(null),(4),(null),(5),(null),(6),(null);

CREATE TABLE bar
(
  id    INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
  val   INT

CREATE TABLE baz
(
  id    INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
  val   INT
);

INSERT INTO baz (val) VALUES
(null),(null),(null),(null),(null),(null);

Query 1:

SELECT  'foo'                   as table_name,
        'mixed null/non-null'   as description,
        21                      as expected_sum,
        COALESCE(SUM(val), 0)   as actual_sum

|        baz |            all null |            0 |          0 |

I wanted to add that there is another possibility - to use the function na().

e.g. =if(a2 = 5,"good",na());

This will fill the cell with #N/A and if you chart the column, the data won't be graphed. I know it isn't "blank" as such, but it's another possibility if you have blank strings in your data and "" is a valid option.

Also, count(a:a) will not count cells which have been set to n/a by doing this.

This is not possible the way you are trying it. The Jackson unmarshalling works on the compiled java code after type erasure. So your

public @ResponseBody ModelMap setTest(@RequestBody List<TestS> refunds, ModelMap map) 

is really only

public @ResponseBody ModelMap setTest(@RequestBody List refunds, ModelMap map) 

(no generics in the list arg).

The default type Jackson creates when unmarshalling a List is a LinkedHashMap.

As mentioned by @Saint you can circumvent this by creating your own type for the list like so:

class TestSList extends ArrayList<TestS> { }

and then modifying your controller signature to

public @ResponseBody ModelMap setTest(@RequestBody TestSList refunds, ModelMap map) {

No external libraries, works on both Python 2.7 and 3.x:

>>> list(set({"a":1, "b": 2}.values()))[0]
1

For aribtrary key just leave out .values()

>>> list(set({"a":1, "b": 2}))[0]
'a'

This is now possible with JPA 2.1:

@Column(name = "RIGHT")
@Enumerated(EnumType.STRING)
private Right right;

The server_name^docs directive is used to identify virtual hosts, they're not used to set the binding.

netstat tells you that nginx listens on 0.0.0.0:80 which means that it will accept connections from any IP.

If you want to change the IP nginx binds on, you have to change the listen^docs rule.
So, if you want to set nginx to bind to localhost, you'd change that to:

listen 127.0.0.1:80;

In this way, requests that are not coming from localhost are discarded (they don't even hit nginx).

I realize this question is a bit dated and since it shows up on Google search for similar issue I thought I will expand a little bit more on top of @CowWarrior's answer. I was looking for somewhat similar solution, and after scouring through countless SO question/answers and Bootstrap documentations the solution was pretty simple. Again, this would be using inbuilt Bootstrap collapse class to show/hide divs and Bootstrap's "Collapse Event".

What I realized is that it is easy to do it using a Bootstrap Accordion, but most of the time even though the functionality required is "somewhat" similar to an Accordion, it's different in a way that one would want to show hide <div> based on, lets say, menu buttons on a navbar. Below is a simple solution to this. The anchor tags (<a>) could be navbar items and based on a collapse event the corresponding div will replace the existing div. It looks slightly sloppy in CodeSnippet, but it is pretty close to achieving the functionality-

All that the JavaScript does is makes all the other <div> hide using

$(".main-container.collapse").not($(this)).collapse('hide');

when the loaded <div> is displayed by checking the Collapse event shown.bs.collapse. Here's the Bootstrap documentation on Collapse Event.

Note: main-container is just a custom class.

Here it goes-

$(".main-container.collapse").on('shown.bs.collapse', function () {    _x000D_
//when a collapsed div is shown hide all other collapsible divs that are visible_x000D_
       $(".main-container.collapse").not($(this)).collapse('hide');_x000D_
});

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>_x000D_
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js"></script>_x000D_
<link href="https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css" rel="stylesheet"/>_x000D_
_x000D_
<a href="#Foo" class="btn btn-default" data-toggle="collapse">Toggle Foo</a>_x000D_
<a href="#Bar" class="btn btn-default" data-toggle="collapse">Toggle Bar</a>_x000D_
_x000D_
<div id="Bar" class="main-container collapse in">_x000D_
    This div (#Bar) is shown by default and can toggle_x000D_
</div>_x000D_
<div id="Foo" class="main-container collapse">_x000D_
    This div (#Foo) is hidden by default_x000D_
</div>

Two ways to do that..

Option 1:

1.  Go to "Start" -> "Run".

2.  Write "CMD" and press on "Enter" key.

3.  Write the command "net statistics server" and press on "Enter" key.

4.  The line that start with "Statistics since …" provides the time that the server was up from.


  The command "net stats srv" can be use instead.

Option 2:

Hope it helped you!!

You could try this:

MyClass.h

class MyClass {
private:
    static const std::map<key, value> m_myMap; 
    static const std::map<key, value> createMyStaticConstantMap();
public:
    static std::map<key, value> getMyConstantStaticMap( return m_myMap );
}; //MyClass

MyClass.cpp

#include "MyClass.h"

const std::map<key, value> MyClass::m_myMap = MyClass::createMyStaticConstantMap();

const std::map<key, value> MyClass::createMyStaticConstantMap() {
    std::map<key, value> mMap;
    mMap.insert( std::make_pair( key1, value1 ) );
    mMap.insert( std::make_pair( key2, value2 ) );
    // ....
    mMap.insert( std::make_pair( lastKey, lastValue ) ); 
    return mMap;
} // createMyStaticConstantMap

With this implementation your classes constant static map is a private member and can be accessible to other classes using a public get method. Otherwise since it is constant and can not change, you can remove the public get method and move the map variable into the classes public section. I would however leave the createMap method private or protected if inheritance and or polymorphism is required. Here are some samples of use.

 std::map<key,value> m1 = MyClass::getMyMap();
 // then do work on m1 or
 unsigned index = some predetermined value
 MyClass::getMyMap().at( index ); // As long as index is valid this will 
 // retun map.second or map->second value so if in this case key is an
 // unsigned and value is a std::string then you could do
 std::cout << std::string( MyClass::getMyMap().at( some index that exists in map ) ); 
// and it will print out to the console the string locted in the map at this index. 
//You can do this before any class object is instantiated or declared. 

 //If you are using a pointer to your class such as:
 std::shared_ptr<MyClass> || std::unique_ptr<MyClass>
 // Then it would look like this:
 pMyClass->getMyMap().at( index ); // And Will do the same as above
 // Even if you have not yet called the std pointer's reset method on
 // this class object. 

 // This will only work on static methods only, and all data in static methods must be available first.

I had edited my original post, there was nothing wrong with the original code in which I posted for it compiled, built and ran correctly, it was just that my first version I presented as an answer the map was declared as public and the map was const but wasn't static.

Try:

<optgroup label="----------"></optgroup>

You could explicitly create a DatetimeIndex when initializing the dataframe. Assuming your data is in string format

data = [
    ('2015-09-25 00:46', '71.925000'),
    ('2015-09-25 00:47', '71.625000'),
    ('2015-09-25 00:48', '71.333333'),
    ('2015-09-25 00:49', '64.571429'),
    ('2015-09-25 00:50', '72.285714'),
]

index, values = zip(*data)

frame = pd.DataFrame({
    'values': values
}, index=pd.DatetimeIndex(index))

print(frame.index.minute)

see man nm

GNU nm lists the symbols from object files objfile.... If no object files are listed as arguments, nm assumes the file a.out.

i achieve it like this..

if(location.pathname == '/registration')
{
$('html, body').animate({ scrollTop: $('#registration').offset().top - 40}, 1000);
}

For checking for a time of day use:

TimeSpan start = new TimeSpan(10, 0, 0); //10 o'clock
TimeSpan end = new TimeSpan(12, 0, 0); //12 o'clock
TimeSpan now = DateTime.Now.TimeOfDay;

if ((now > start) && (now < end))
{
   //match found
}

For absolute times use:

DateTime start = new DateTime(2009, 12, 9, 10, 0, 0)); //10 o'clock
DateTime end = new DateTime(2009, 12, 10, 12, 0, 0)); //12 o'clock
DateTime now = DateTime.Now;

if ((now > start) && (now < end))
{
   //match found
}

I ran into a similar error

"from: can't read /var/mail/django.test.utils"

when trying to run a command

>>> from django.test.utils import setup_test_environment
>>> setup_test_environment()

in the tutorial at https://docs.djangoproject.com/en/1.8/intro/tutorial05/

after reading the answer by Tamás I realized I was not trying this command in the python shell but in the termnial (this can happen to those new to linux)

solution was to first enter in the python shell with the command python and when you get these >>> then run any python commands

Try this:

printf '\n%s\n' 'I want this on a new line!'

That allows you to separate the formatting from the actual text. You can use multiple placeholders and multiple arguments.

quantity=38; price=142.15; description='advanced widget'
$ printf '%8d%10.2f  %s\n' "$quantity" "$price" "$description"
      38    142.15  advanced widget

Here's a derived HorizontalScrollView I wrote to handle notifications about scrolling and scroll ending. It properly handles when a user has stopped actively scrolling and when it fully decelerates after a user lets go:

public class ObservableHorizontalScrollView extends HorizontalScrollView {
    public interface OnScrollListener {
        public void onScrollChanged(ObservableHorizontalScrollView scrollView, int x, int y, int oldX, int oldY);
        public void onEndScroll(ObservableHorizontalScrollView scrollView);
    }

    private boolean mIsScrolling;
    private boolean mIsTouching;
    private Runnable mScrollingRunnable;
    private OnScrollListener mOnScrollListener;

    public ObservableHorizontalScrollView(Context context) {
        this(context, null, 0);
    }

    public ObservableHorizontalScrollView(Context context, AttributeSet attrs) {
        this(context, attrs, 0);
    }

    public ObservableHorizontalScrollView(Context context, AttributeSet attrs, int defStyle) {
        super(context, attrs, defStyle);
    }

    @Override
    public boolean onTouchEvent(MotionEvent ev) {
        int action = ev.getAction();

        if (action == MotionEvent.ACTION_MOVE) {
            mIsTouching = true;
            mIsScrolling = true;
        } else if (action == MotionEvent.ACTION_UP || action == MotionEvent.ACTION_CANCEL) {
            if (mIsTouching && !mIsScrolling) {
                if (mOnScrollListener != null) {
                    mOnScrollListener.onEndScroll(this);
                }
            }

            mIsTouching = false;
        }

        return super.onTouchEvent(ev);
    }

    @Override
    protected void onScrollChanged(int x, int y, int oldX, int oldY) {
        super.onScrollChanged(x, y, oldX, oldY);

        if (Math.abs(oldX - x) > 0) {
            if (mScrollingRunnable != null) {
                removeCallbacks(mScrollingRunnable);
            }

            mScrollingRunnable = new Runnable() {
                public void run() {
                    if (mIsScrolling && !mIsTouching) {
                        if (mOnScrollListener != null) {
                            mOnScrollListener.onEndScroll(ObservableHorizontalScrollView.this);
                        }
                    }

                    mIsScrolling = false;
                    mScrollingRunnable = null;
                }
            };

            postDelayed(mScrollingRunnable, 200);
        }

        if (mOnScrollListener != null) {
            mOnScrollListener.onScrollChanged(this, x, y, oldX, oldY);
        }
    }

    public OnScrollListener getOnScrollListener() {
        return mOnScrollListener;
    }

    public void setOnScrollListener(OnScrollListener mOnEndScrollListener) {
        this.mOnScrollListener = mOnEndScrollListener;
    }

}

Some time has passed since this was asked.

Now it is possible to not only specify number to window.scroll function, but also pass an object with three properties: top, left and behavior. So if we would like to have a smooth scroll up with native JavaScript, we can now do something like this:

let button = document.querySelector('button-id');
let options = {top: 0, left: 0, behavior: 'smooth'}; // left and top are coordinates
button.addEventListener('click', () => { window.scroll(options) });

https://developer.mozilla.org/en-US/docs/Web/API/Window/scroll

You can use math.ceil() to round up, and then multiply by 10

import math

def roundup(x):
    return int(math.ceil(x / 10.0)) * 10

To use just do

>>roundup(45)
50

Let me explain a little more by my example.

Task: correct info, where abiturients (students about to leave secondary school) have submitted applications to university earlier, than they got school certificates (yes, they got certificates earlier, than they were issued (by certificate date specified). So, we will increase application submit date to fit certificate issue date.

Thus. next MySQL-like statement:

UPDATE applications a
JOIN (
    SELECT ap.id, ab.certificate_issued_at
    FROM abiturients ab
    JOIN applications ap 
    ON ab.id = ap.abiturient_id 
    WHERE ap.documents_taken_at::date < ab.certificate_issued_at
) b
ON a.id = b.id
SET a.documents_taken_at = b.certificate_issued_at;

Becomes PostgreSQL-like in such a way

UPDATE applications a
SET documents_taken_at = b.certificate_issued_at         -- we can reference joined table here
FROM abiturients b                                       -- joined table
WHERE 
    a.abiturient_id = b.id AND                           -- JOIN ON clause
    a.documents_taken_at::date < b.certificate_issued_at -- Subquery WHERE

As you can see, original subquery JOIN's ON clause have become one of WHERE conditions, which is conjucted by AND with others, which have been moved from subquery with no changes. And there is no more need to JOIN table with itself (as it was in subquery).

For this you can simply use the "HttpWebRequest" and "HttpWebResponse" classes in .net.

Below is a sample console app I wrote to demonstrate how easy this is.

using System;
using System.Collections.Generic;
using System.Text;
using System.Net;
using System.IO;

namespace Test
{
    class Program
    {
        static void Main(string[] args)
        {
            string url = "www.somewhere.com";       
            string fileName = @"C:\output.file";

            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            request.Timeout = 5000;

            try
            {
                using (WebResponse response = (HttpWebResponse)request.GetResponse())
                {
                    using (FileStream stream = new FileStream(fileName, FileMode.Create, FileAccess.Write))
                    {
                        byte[] bytes = ReadFully(response.GetResponseStream());

                        stream.Write(bytes, 0, bytes.Length);
                    }
                }
            }
            catch (WebException)
            {
                Console.WriteLine("Error Occured");
            }
        }

        public static byte[] ReadFully(Stream input)
        {
            byte[] buffer = new byte[16 * 1024];
            using (MemoryStream ms = new MemoryStream())
            {
                int read;
                while ((read = input.Read(buffer, 0, buffer.Length)) > 0)
                {
                    ms.Write(buffer, 0, read);
                }
                return ms.ToArray();
            }
        }
    }
}

Enjoy!

There is a much more concise way to do this. Arguments to a bash script can be brought into an array, which makes dealing with the elements much simpler. The script below will always print the last argument passed to a script.

  argArray=( "$@" )                        # Add all script arguments to argArray
  arrayLength=${#argArray[@]}              # Get the length of the array
  lastArg=$((arrayLength - 1))             # Arrays are zero based, so last arg is -1
  echo ${argArray[$lastArg]}

Sample output

$ ./lastarg.sh 1 2 buckle my shoe
shoe

You are using the wrong iteration counter, replace inp.charAt(i) with inp.charAt(j).

One workaround that I have done is:

• Ctrl + a to select everything in the slide
• Ctrl + c to copy it
• open GIMP (probably works in Photoshop or other software)
• make a new image with a transparent background
• Ctrl + v to paste all the vectors/text into the image
• Export the image to a PNG or whatever format

It looks pretty much exactly the same as in Powerpoint, and the vectors/text are very clean with their transparency edges.

for i in iterator:
    try:
        # Do something.
        pass
    except:
        # Continue to next iteration.
        continue

Install it by running

python setup.py install

Better yet, you can download from github. Install git via apt-get install git and then follow this steps:

git clone https://github.com/mwaskom/seaborn.git
cd seaborn
python setup.py install

Nuget Gallery provides a GUI similar to the full Visual Studio. See below.

How To Use:

1. Install Nuget Gallery from extension marketplace.
2. Launch from the menu bar View > Command Palette or ??P (Ctrl+Shift+P on Windows and Linux). Type Nuget: Open Gallery.
3. The GUI above is displayed. You can filter just like in regular Visual Studio.
4. Make sure the .csproj file checkbox is selected, select version from dropdown, and click install button.

UPDATE

Earlier versions, as noted in the comments, had an issue where the .csproj checkbox was not visible when a package in the csproj file was missing a version number like below.

<PackageReference Include="Microsoft.AspNetCore.App" />

This has been fixed in newer versions of the extension so if you have an older version with this issue, please update it to the latest version.

You can use parsing with double instead of float to get more precision value.

I have written a tool to automatically strong-name sign assemblies including ones you do not have the source code for or projects that have been abandoned. It uses many of the techniques described in the answers in a simple way without any of the flaws or drawbacks of existing tools or dated instructions.

Hope this helps out anyone that need to sign a third party assembly without having to jump through hoops to get there.

We have similar situation right now and as of this answer, I am using laravel 5.6 release.

I will not use your example in the question but mine, because it's related though.

I have route like this:

Route::name('your.name.here')->get('/your/uri', 'YourController@someMethod');

Then in your controller method, make sure you include

use Illuminate\Http\Request;

and this should be above your controller, most likely a default, if generated using php artisan, now to get variable from the url it should look like this:

  public function someMethod(Request $request)
  {
    $foo = $request->input("start");
    $bar = $request->input("limit");

    // some codes here
  }

Regardless of the HTTP verb, the input() method may be used to retrieve user input.

Hope this help.

To understand why jQuery is so popular, it's important to understand where we're coming from!

About a decade ago, top browsers were IE6, Netscape 8 and Firefox 1.5. Back in those days, there were little cross-browser ways to select an element from the DOM besides Document.getElementById().

So, when jQuery was released back in 2006, it was pretty revolutionary. Back then, jQuery set the standard for how to easily select / change HTML elements and trigger events, because its flexibility and browser support were unprecedented.

Now, more than a decade later, a lot of features that made jQuery so popular have become included in the javaScript standard:

• Instead of jQuery's $(), you can now now use Document.querySelectorAll()
• Instead of jQuery's $el.on(), you can now use EventTarget.addEventListener()
• Instead of jQuery's $el.toggleClass(), you can now use Element.classList.toggle()
• ...

These weren't generally available back in 2005. The fact that they are today obviously begs the question of why we should use jQuery at all. And indeed, people are increasingly wondering whether we should use jQuery at all.

So, if you think you understand JavaScript well enough to do without jQuery, please do! Don't feel forced to use jQuery, just because so many others are doing it!

All other answers sounds good, I would like to cover my case, where I had to make an animated LaunchScreen, then after 3 to 4 seconds of animation the next task was to move to Home screen. I tried segues, but that created problem for destination view. So at the end I accessed AppDelegates's Window property and I assigned a new NavigationController screen to it,

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let appDelegate = UIApplication.shared.delegate as! AppDelegate
let homeVC = storyboard.instantiateViewController(withIdentifier: "HomePageViewController") as! HomePageViewController

//Below's navigationController is useful if u want NavigationController in the destination View
let navigationController = UINavigationController(rootViewController: homeVC)
appDelegate.window!.rootViewController = navigationController

If incase, u don't want navigationController in the destination view then just assign as,

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let appDelegate = UIApplication.shared.delegate as! AppDelegate
let homeVC = storyboard.instantiateViewController(withIdentifier: "HomePageViewController") as! HomePageViewController
appDelegate.window!.rootViewController = homeVC

You can use CSS3 font-face or webfonts

@font-face usage

@font-face {
   font-family: Delicious; 
   src: url('Delicious-Roman.otf');
} 

webfonts

take a look at Google Webfonts, http://www.google.com/webfonts

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.

If you're not sure your input is going to be a Numpy array, you can use asarray with dtype=int instead of astype:

>>> np.asarray([1,2,3,4], dtype=int)
array([1, 2, 3, 4])

If the input array already has the correct dtype, asarray avoids the array copy while astype does not (unless you specify copy=False):

>>> a = np.array([1,2,3,4])
>>> a is np.asarray(a)  # no copy :)
True
>>> a is a.astype(int)  # copy :(
False
>>> a is a.astype(int, copy=False)  # no copy :)
True

This sounds like your browser is caching your css. If you are using Firefox, try loading your page using Shift-Reload.

In addition to the accepted answer, if you are using Android Studio you can

1. invoke Android Device Monitor,
2. select the device in the Devices tab on the left,
3. select File Explorer tab on the right,
4. navigate to the file you want, and
5. click the Pull a file from the device button to save it to your local file system

Fast and easy with HAVING:

SELECT * FROM tblpm n 
FROM tblpm GROUP BY control_number 
HAVING date_updated=MAX(date_updated);

In the context of HAVING, MAX finds the max of each group. Only the latest entry in each group will satisfy date_updated=max(date_updated). If there's a tie for latest within a group, both will pass the HAVING filter, but GROUP BY means that only one will appear in the returned table.
