Note that for this particular application there's a standard library function, android.text.format.DateUtils.getRelativeTimeSpanString().

For Bootstrap 3 the default radio/button-group structure is :

<div class="btn-group" data-toggle="buttons">
    <label class="btn btn-primary">
        <input type="radio" name="options" id="option1"> Option 1
    </label>
    <label class="btn btn-primary">
        <input type="radio" name="options" id="option2"> Option 2
    </label>
    <label class="btn btn-primary">
        <input type="radio" name="options" id="option3"> Option 3
    </label>
</div>

And you can select the active one like this:

$('.btn-primary').on('click', function(){
    alert($(this).find('input').attr('id'));
}); 

If the table has an ID:

const tableObject = document.getElementById(tableId);
const rowCount = tableObject[1].childElementCount;

If the table has a Class:

const tableObject = document.getElementsByClassName(tableClass);
const rowCount = tableObject[1].childElementCount;

If the table has a Name:

const tableObject = document.getElementsByTagName('table');
const rowCount = tableObject[1].childElementCount;

Note: index 1 represents <tbody> tag

I had the following error message Port 80 in use by "Unable to open process" with PID 4! Apache WILL NOT start without the configured ports free! You need to uninstall/disable/reconfigure the blocking application or reconfigure Apache and the Control Panel to listen on a different port Starting Check-Timer Control Panel Ready

opened the httpd.conf and changed the listen port from 80 to 1234 in both places

Listen 12.34.56.78:1234

Listen 1234

Then go to Config for the xampp control panel and go to service and port setting and changed the port from 80 to 1234

That worked.

It depends upon the context. Some possible contexts in HTML:

• document body
• inside common attributes
• inside script tags
• inside style tags
• several more!

See OWASP's Cross Site Scripting Prevention Cheat Sheet, especially the "Why Can't I Just HTML Entity Encode Untrusted Data?" and "XSS Prevention Rules" sections. However, it's best to read the whole document.

I've got this, which is working in FF3, IE6 & 7. The methods in the on-demand loaded scripts aren't available until page load is complete, but this is still very useful.

//handle on-demand loading of javascripts
makescript = function(url){
    var v = document.createElement('script');
    v.src=url;
    v.type='text/javascript';

    //insertAfter. Get last <script> tag in DOM
    d=document.getElementsByTagName('script')[(document.getElementsByTagName('script').length-1)];
    d.parentNode.insertBefore( v, d.nextSibling );
}

Better you update your eclipse by clicking it on help >> check for updates, also you can start eclipse by entering command in command prompt eclipse -clean.
Hope this will help you.

Without contentInset, a table view is like this:

Then set contentInset:

tableView.contentInset = UIEdgeInsets(top: 20, left: 0, bottom: 0, right: 0)

The effect is as below:

Seems to be better, right?

And I write a blog to study the contentInset, criticism is welcome.

If, for some reason, what karmakaze said doesn't work, you could try deleting the directory you want using or with your file system browser (ex. In Windows File Explorer). After deleting the directory, issuing the command:
git add -A
and then
git commit -m 'deleting directory'
and then
git push origin master.

Personally I use PDO, but I think that is mainly a question of preference.

PDO has some features that help agains SQL injection (prepared statements), but if you are careful with your SQL you can achieve that with mysqli, too.

Moving to another database is not so much a reason to use PDO. As long as you don't use "special SQL features", you can switch from one DB to another. However as soon as you use for example "SELECT ... LIMIT 1" you can't go to MS-SQL where it is "SELECT TOP 1 ...". So this is problematic anyway.

This worked for me

• install stylebot extension from webstore https://chrome.google.com/webstore/detail/stylebot/oiaejidbmkiecgbjeifoejpgmdaleoha
• go to G-document, set appropriate minimal view mode
• click stylebot icon (css) in toolbar of Chrome
• click "Open Stylebot"
• on very first line of new window, which is reading "select an element", insert text .kix-page-compact::before
• set border-style to none

Other than that open the "View" menu at the top of the screen and un-check "Print Layout." Page breaks will now only be shown as a dashed line.

It worked for me when I called CancelCallBacks(this) inside the post delayed runnable by handing it via a boolean

Runnable runnable = new Runnable(){
    @Override
    public void run() {
        Log.e("HANDLER", "run: Outside Runnable");
        if (IsRecording) {
            Log.e("HANDLER", "run: Runnable");
            handler.postDelayed(this, 2000);
        }else{
            handler.removeCallbacks(this);
        }
    }
};

If you need this for PHP:

The PHP DOM functions won't work properly unless it is properly formatted XML. No matter how much better their use is for the rest of mankind.

simplehtmldom is good, but I found it a bit buggy, and it is is quite memory heavy [Will crash on large pages.]

I have never used querypath, so can't comment on its usefulness.

Another one to try is my DOMParser which is very light on resources and I've been using happily for a while. Simple to learn & powerful.

For Python and Java, similar links were posted.

For the downvoters - I only wrote my class when the XML parsers proved unable to withstand real use. Religious downvoting just prevents useful answers from being posted - keep things within perspective of the question, please.

You don't need to. Just slap it on there as many times as you want and as often as you want. MDN explains identical event listeners:

If multiple identical EventListeners are registered on the same EventTarget with the same parameters, the duplicate instances are discarded. They do not cause the EventListener to be called twice, and they do not need to be removed manually with the removeEventListener method.

Try following Steps for Apache

• Go to your XAMPP installation folder. Right-click xampp-control.exe. Click "Run as administrator"
• Stop Apache service action port
• Tick this (in snapshot) check box. It will ask if you want to install as service. Click "Yes".

• Go to Windows Services by typing Window + R, then typing services.msc

• Enter a new service name as Apache2 (or similar)

• Set it as automatic, if you want it to run as startup.

Sure you can use Swift!

1. Adding the video file

Add the video (lets call it video.m4v) to your Xcode project

2. Checking your video is into the Bundle

Open the Project Navigator cmd + 1

Then select your project root > your Target > Build Phases > Copy Bundle Resources.

Your video MUST be here. If it's not, then you should add it using the plus button

3. Code

Open your View Controller and write this code.

import UIKit
import AVKit
import AVFoundation

class ViewController: UIViewController {

    override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        playVideo()
    }

    private func playVideo() {
        guard let path = Bundle.main.path(forResource: "video", ofType:"m4v") else {
            debugPrint("video.m4v not found")
            return
        }
        let player = AVPlayer(url: URL(fileURLWithPath: path))
        let playerController = AVPlayerViewController()
        playerController.player = player
        present(playerController, animated: true) {
            player.play()
        }
    }
}

At least on 2008R2 if the accounts are only used for RDP and not for local logins then you can set this on a per-account basis. That should work for thin clients. If the accounts are also used on local desktops then this would also affect those logins.

In ADUsers&Computers, open the properties for the account and go to the Environment tab. On that tab, check "Start the following program at logon" and specify the path and executable for the program.

fetch("http://localhost:8988/api", {
        //mode: "no-cors",
        method: "GET",
        headers: {
            "Accept": "application/json"
        }
    })
    .then(response => {
        return response.json();
    })
    .then(data => {
        return data;
    })
    .catch(error => {
        return error;
    });

This works for me.

This code will count frequency and remove duplicate elements:

from collections import Counter

str1='the cat sat on the hat hat'

int_list=str1.split();

unique_list = []
for el in int_list:

    if el not in unique_list:
        unique_list.append(el)
    else:
        print "Element already in the list"

print unique_list

c=Counter(int_list)

c.values()

c.keys()

print c

Spring sets the default content-type to octet-stream when the response is missing that field. All you need to do is to add a message converter to fix this.

Questions 1 & 2

So basically, first parameter is the object to iterate on. It can be an array or an object. If it is an object like this :

var values = {name: 'misko', gender: 'male'};

Angular will take each value one by one the first one is name, the second is gender.

If your object to iterate on is an array (also possible), like this :

[{ "Name" : "Thomas", "Password" : "thomasTheKing" },
 { "Name" : "Linda", "Password" : "lindatheQueen" }]

Angular.forEach will take one by one starting by the first object, then the second object.

For each of this object, it will so take them one by one and execute a specific code for each value. This code is called the iterator function. forEach is smart and behave differently if you are using an array of a collection. Here is some exemple :

var obj = {name: 'misko', gender: 'male'};
var log = [];
angular.forEach(obj, function(value, key) {
  console.log(key + ': ' + value);
});
// it will log two iteration like this
// name: misko
// gender: male

So key is the string value of your key and value is ... the value. You can use the key to access your value like this : obj['name'] = 'John'

If this time you display an array, like this :

var values = [{ "Name" : "Thomas", "Password" : "thomasTheKing" },
           { "Name" : "Linda", "Password" : "lindatheQueen" }];
angular.forEach(values, function(value, key){
     console.log(key + ': ' + value);
});
// it will log two iteration like this
// 0: [object Object]
// 1: [object Object]

So then value is your object (collection), and key is the index of your array since :

[{ "Name" : "Thomas", "Password" : "thomasTheKing" },
 { "Name" : "Linda", "Password" : "lindatheQueen" }]
// is equal to
{0: { "Name" : "Thomas", "Password" : "thomasTheKing" },
 1: { "Name" : "Linda", "Password" : "lindatheQueen" }}

I hope it answer your question. Here is a JSFiddle to run some code and test if you want : http://jsfiddle.net/ygahqdge/

Debugging your code

The problem seems to come from the fact $http.get() is an asynchronous request.

You send a query on your son, THEN when you browser end downloading it it execute success. BUT just after sending your request your perform a loop using angular.forEach without waiting the answer of your JSON.

You need to include the loop in the success function

var app = angular.module('testModule', [])
    .controller('testController', ['$scope', '$http', function($scope, $http){
    $http.get('Data/info.json').then(function(data){
         $scope.data = data;

         angular.forEach($scope.data, function(value, key){
         if(value.Password == "thomasTheKing")
           console.log("username is thomas");
         });
    });

});

This should work.

Going more deeply

The $http API is based on the deferred/promise APIs exposed by the $q service. While for simple usage patterns this doesn't matter much, for advanced usage it is important to familiarize yourself with these APIs and the guarantees they provide.

You can give a look at deferred/promise APIs, it is an important concept of Angular to make smooth asynchronous actions.

I believe you can use multiprocessing and not depend on a 3rd party package:

import multiprocessing
import requests

def call_with_timeout(func, args, kwargs, timeout):
    manager = multiprocessing.Manager()
    return_dict = manager.dict()

    # define a wrapper of `return_dict` to store the result.
    def function(return_dict):
        return_dict['value'] = func(*args, **kwargs)

    p = multiprocessing.Process(target=function, args=(return_dict,))
    p.start()

    # Force a max. `timeout` or wait for the process to finish
    p.join(timeout)

    # If thread is still active, it didn't finish: raise TimeoutError
    if p.is_alive():
        p.terminate()
        p.join()
        raise TimeoutError
    else:
        return return_dict['value']

call_with_timeout(requests.get, args=(url,), kwargs={'timeout': 10}, timeout=60)

The timeout passed to kwargs is the timeout to get any response from the server, the argument timeout is the timeout to get the complete response.

you need to make county_ID as index for the right frame:

frame_2.join ( frame_1.set_index( [ 'county_ID' ], verify_integrity=True ),
               on=[ 'countyid' ], how='left' )

for your information, in pandas left join breaks when the right frame has non unique values on the joining column. see this bug.

so you need to verify integrity before joining by , verify_integrity=True

You can use the Conditional Formatting to replace text and NOT effect any formulas. Simply go to the Rule's format where you will see Number, Font, Border and Fill.
Go to the Number tab and select CUSTOM. Then simply type where it says TYPE: what you want to say in QUOTES.

Example.. "OTHER"

You can simply use datetime diff and format for calculating difference.

<?php
$datetime1 = new DateTime('2009-10-11 12:12:00');
$datetime2 = new DateTime('2009-10-13 10:12:00');
$interval = $datetime1->diff($datetime2);
echo $interval->format('%Y-%m-%d %H:%i:%s');
?>

For more information OF DATETIME format, refer: here
You can change the interval format in the way,you want.

Here is the working example

P.S. These features( diff() and format()) work with >=PHP 5.3.0 only

Use inline styles:

Fiddle

The inherit value, when used, means that the value of the property is set to the value of the same property of the parent element. For the root element (in HTML documents, for the html element) there is no parent element; by definition, the value used is the initial value of the property. The initial value is defined for each property in CSS specifications.

The font-family property is special in the sense that the initial value is not fixed in the specification but defined to be browser-dependent. This means that the browser’s default font family is used. This value can be set by the user.

If there is a continuous chain of elements (in the sense of parent-child relationships) from the root element to the current element, all with font-family set to inherit or not set at all in any style sheet (which also causes inheritance), then the font is the browser default.

This is rather uninteresting, though. If you don’t set fonts at all, browsers defaults will be used. Your real problem might be different – you seem to be looking at the part of style sheets that constitute a browser style sheet. There are probably other, more interesting style sheets that affect the situation.

var newurl = window.location.protocol + "//" + window.location.host + window.location.pathname + '?foo=bar';

Define a class to store your data first

public class YourDataClass {

    private String messageType;
    private Timestamp timestamp;
    private int count;
    private int version;

    // your get/setters
    ...........
}

And then initialize your map:

Map<Integer, YourDataClass> map = new HashMap<Integer, YourDataClass>();

Well I did not think this was possible until I went and checked. In some previous version of Excel I could not do this. I am currently using Excel 2013.

This is what you want to do in a scatter plot:

1. right click on your data point

2. select "Format Data Labels" (note you may have to add data labels first)

3. put a check mark in "Values from Cells"
4. click on "select range" and select your range of labels you want on the points

UPDATE: Colouring Individual Labels

In order to colour the labels individually use the following steps:

1. select a label. When you first select, all labels for the series should get a box around them like the graph above.
2. Select the individual label you are interested in editing. Only the label you have selected should have a box around it like the graph below.
3. On the right hand side, as shown below, Select "TEXT OPTIONS".
4. Expand the "TEXT FILL" category if required.
5. Second from the bottom of the category list is "COLOR", select the colour you want from the pallet.

If you have the entire series selected instead of the individual label, text formatting changes should apply to all labels instead of just one.

Installing the Microsoft Visual C++ Redistributable for Visual Studio 2015, 2017 and 2019 worked for me with a similar problem, and helped with another (slightly different) driver issue.

Here's a fun way to do it with a decorator:

def restartable(func):
    def wrapper(*args,**kwargs):
        answer = 'y'
        while answer == 'y':
            func(*args,**kwargs)
            while True:
                answer = raw_input('Restart?  y/n:')
                if answer in ('y','n'):
                    break
                else:
                    print "invalid answer"
    return wrapper

@restartable
def main():
    print "foo"

main()

Ultimately, I think you need 2 while loops. You need one loop bracketing the portion which prompts for the answer so that you can prompt again if the user gives bad input. You need a second which will check that the current answer is 'y' and keep running the code until the answer isn't 'y'.

The (A==B).all() solution is very neat, but there are some built-in functions for this task. Namely array_equal, allclose and array_equiv.

(Although, some quick testing with timeit seems to indicate that the (A==B).all() method is the fastest, which is a little peculiar, given it has to allocate a whole new array.)

I have to destroy the modal right after it is closed through a button click, and so I came up with the following.

$("#closeModal").click(function() {
    $("#modal").modal('hide').on('hidden.bs.modal', function () {
        $("#modal").remove();
    });
});

Note that this works with Bootstrap 3.

As everyone has pointed out, you'll do this by setting a float:right; on the RHS content and a negative margin on the LHS.

However.. if you don't use a float: left; on the LHS (as Mohit does) then you'll get a stepping effect because the LHS div is still going to consume the margin'd space in layout.

However.. the LHS float will shrink-wrap the content, so you'll need to insert a defined width childnode if that's not acceptable, at which point you may as well have defined the width on the parent.

However.. as David points out you can change the read-order of the markup to avoid the LHS float requirement, but that's has readability and possibly accessibility issues.

However.. this problem can be solved with floats given some additional markup

(caveat: I don't approve of the .clearing div at that example, see here for details)

All things considered, I think most of us wish there was a non-greedy width:remaining in CSS3...

The answer above didn't work for me.

I added the following code before my ajax request:

                var cookieValue = null;
                if (document.cookie && document.cookie != '') {
                    var cookies = document.cookie.split(';');
                    for (var i = 0; i < cookies.length; i++) {
                        var cookie = jQuery.trim(cookies[i]);
                        // Does this cookie string begin with the name we want?
                        if (cookie.substring(0, name.length + 1) == (name + '=')) {
                            cookieValue = decodeURIComponent(cookie.substring(name.length + 1));
                            break;
                        }
                    }
                }
                return cookieValue;
            }
            var csrftoken = getCookie('csrftoken');

            function csrfSafeMethod(method) {
                // these HTTP methods do not require CSRF protection
                return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
            }

            $.ajaxSetup({
                beforeSend: function(xhr, settings) {
                    if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
                        xhr.setRequestHeader("X-CSRFToken", csrftoken);
                    }
                }
            });

UPDATE

Consider avoiding createObjectURL() method, while browsers are disabling support for it. Just attach MediaStream object directly to the srcObject property of HTMLMediaElement e.g. <video> element.

const mediaStream = new MediaStream();
const video = document.getElementById('video-player');
video.srcObject = mediaStream;

However, if you need to work with MediaSource, Blob or File, you have to create a URL with URL.createObjectURL() and assign it to HTMLMediaElement.src.

Read more details here: https://developer.mozilla.org/en-US/docs/Web/API/HTMLMediaElement/srcObject

Older Answer

I experienced same error, when I passed to createObjectURL raw data:

window.URL.createObjectURL(data)

It has to be Blob, File or MediaSource object, not data itself. This worked for me:

var binaryData = [];
binaryData.push(data);
window.URL.createObjectURL(new Blob(binaryData, {type: "application/zip"}))

Check also the MDN for more info: https://developer.mozilla.org/en-US/docs/Web/API/URL/createObjectURL

I had a similar problem. I had installed JDK7 update 1 but couldn't use it (probably because I found a JRE6 that I deleted after installing JDK7). Uninstalling JDK7 was impossible. The solution was to add the JRE registry entries by hand.

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment]
"CurrentVersion"="1.7"

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.7]
"JavaHome"="C:\\Program Files\\Java\\jre7"
"RuntimeLib"="C:\\Program Files\\Java\\jre7\\bin\\client\\jvm.dll"

[HKEY_LOCAL_MACHINE\SOFTWARE\JavaSoft\Java Runtime Environment\1.7.0_01]
"JavaHome"="C:\\Program Files\\Java\\jre7"
"RuntimeLib"="C:\\Program Files\\Java\\jre7\\bin\\client\\jvm.dll"

You'll have to adjust the above to your own directories and version.

If this doesn't help, there's still JavaRa http://raproducts.org/wordpress/ .

Use trim and val.

var value=$.trim($("#spa").val());

if(value.length>0)
{
 //do some stuffs. 
}

val() : return the value of the input.

trim(): will trim the white spaces.

I would use XMLHTTP request to retrieve page content as much faster. Then it is easy enough to use querySelectorAll to apply a CSS class selector to grab by class name. Then you access the child elements by tag name and index.

Option Explicit
Public Sub GetInfo()
    Dim sResponse As String, html As HTMLDocument, elements As Object, i As Long

    With CreateObject("MSXML2.XMLHTTP")
        .Open "GET", "https://www.hsbc.com/about-hsbc/leadership", False
        .setRequestHeader "If-Modified-Since", "Sat, 1 Jan 2000 00:00:00 GMT"
        .send
        sResponse = StrConv(.responseBody, vbUnicode)
    End With
    Set html = New HTMLDocument
    With html
        .body.innerHTML = sResponse
        Set elements = .querySelectorAll(".profile-col1")
        For i = 0 To elements.Length - 1
            Debug.Print String(20, Chr$(61))
            Debug.Print elements.item(i).getElementsByTagName("a")(0).innerText
            Debug.Print elements.item(i).getElementsByTagName("p")(0).innerText
            Debug.Print elements.item(i).getElementsByTagName("p")(1).innerText
        Next
    End With
End Sub

To start, Joe Kington's answer provides very good advice using a gui-neutral approach, and you should definitely take his advice (especially about Blitting) and put it into practice. More info on this approach, read the Matplotlib Cookbook

However, the non-GUI-neutral (GUI-biased?) approach is key to speeding up the plotting. In other words, the backend is extremely important to plot speed.

Put these two lines before you import anything else from matplotlib:

import matplotlib
matplotlib.use('GTKAgg') 

Of course, there are various options to use instead of GTKAgg, but according to the cookbook mentioned before, this was the fastest. See the link about backends for more options.

The Tkinter library is built-in with every Python installation. And since you are on Windows, I believe you installed Python through the binaries on their website?

If so, Then most probably you are typing the command wrong. It should be:

import Tkinter as tk

Note the capital T at the beginning of Tkinter.

For Python 3,

import tkinter as tk

Updated for c# 6:

    try
    {
        // some code
    }
    catch (SqlException ex) when (ex.Number == -2)  // -2 is a sql timeout
    {
        // handle timeout
    }

Very simple and nice to look at!!

Source article: Passing a list as an argument to a vararg method

Use the toArray(T[] arr) method.

.getMap(locations.toArray(new WorldLocation[locations.size()]))

(toArray(new WorldLocation[0]) also works, but you would allocate a zero-length array for no reason.)

Here's a complete example:

public static void method(String... strs) {
    for (String s : strs)
        System.out.println(s);
}

...
    List<String> strs = new ArrayList<String>();
    strs.add("hello");
    strs.add("world");
    
    method(strs.toArray(new String[strs.size()]));
    //     ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
...

For anyone who might still need this in the future. My answer is very similar to qaweb, just a lot less intimidating. There seems to be no cool automatic simple function to formate date in VBS. So you'll have to do it manually. I took the different components of the date and concatenated them together.

Dim timeStamp
timeStamp = Month(Date)&"-"&Day(Date)&"-"&Year(Date)
run = msgbox(timeStamp)

Which will result in 11-22-2019 (depending on the current date)

I wrote a blog post on this subject, after spending hours wading through Amazon's obscure documentation. Maybe useful as another view on the process.

You could use SQL.js which is the SQLlite lib compiled to JavaScript and store the database in the local storage introduced in HTML5.

In Python 2.x, it is not guaranteed at all:

>>> False = 5
>>> 0 == False
False

So it could change. In Python 3.x, True, False, and None are reserved words, so the above code would not work.

In general, with booleans you should assume that while False will always have an integer value of 0 (so long as you don't change it, as above), True could have any other value. I wouldn't necessarily rely on any guarantee that True==1, but on Python 3.x, this will always be the case, no matter what.

SELECT distinct
  group, 
  max_date = MAX(date) OVER (PARTITION BY group), checks
FROM table

Should work.

As you can't run --disable-web-security and a normal chrome in parallel it's probably a good solution to use Opera for --disable-web-security

Here is how to create a launcher for opera on windows. By the way, Opera has the same debugging tools as chrome!

http://www.opera.com/

:: opera-browse-dangerously.bat
cd c:\Program Files\Opera\
launcher.exe --disable-web-security --user-data-dir="c:\opera-dev"

PS: Opera doesn't display any notification when started without web-security

Additionally to what Chris Taylor wrote: if you have something serialized as an attribute, you can have a property on your class named {PropertyName}Specified to control if it should be serialized. In code:

public class MyClass

    [XmlAttribute]
    public int MyValue;

    [XmlIgnore]
    public bool MyValueSpecified;
}

split the file "file.txt" into 10000 lines files:

Short answer

datetime.now(timezone.utc).isoformat().replace("+00:00", "Z")

Long answer

The reason that the "Z" is not included is because datetime.now() and even datetime.utcnow() return timezone naive datetimes, that is to say datetimes with no timezone information associated. To get a timezone aware datetime, you need to pass a timezone as an argument to datetime now. For example:

from datetime import datetime, timezone

datetime.utcnow()
#> datetime.datetime(2020, 9, 3, 20, 58, 49, 22253)
# This is timezone naive

datetime.now(timezone.utc)
#> datetime.datetime(2020, 9, 3, 20, 58, 49, 22253, tzinfo=datetime.timezone.utc)
# This is timezone aware

Once you have a timezone aware timestamp, isoformat will include a timezone designation. Thus, you can then get an ISO 8601 timestamp via:

datetime.now(timezone.utc).isoformat()
#> '2020-09-03T20:53:07.337670+00:00'

"+00:00" is a valid ISO 8601 timezone designation for UTC. If you want to have "Z" instead of "+00:00", you have to do the replacement yourself:

datetime.now(timezone.utc).isoformat().replace("+00:00", "Z")
#> '2020-09-03T20:53:07.337670Z'

Others have provided answers for how to change the title size, but as for the axes tick label size, you can also use the set_tick_params method.

E.g., to make the x-axis tick label size small:

ax.xaxis.set_tick_params(labelsize='small')

or, to make the y-axis tick label large:

ax.yaxis.set_tick_params(labelsize='large')

You can also enter the labelsize as a float, or any of the following string options: 'xx-small', 'x-small', 'small', 'medium', 'large', 'x-large', or 'xx-large'.

you can do this with jdk >= 8

getComboBox().addItemListener(this::comboBoxitemStateChanged);

so

public void comboBoxitemStateChanged(ItemEvent e) {
    if (e.getStateChange() == ItemEvent.SELECTED) {
        YourObject selectedItem = (YourObject) e.getItem();
        //TODO your actitons
    }
}

Below are two methods that are superior to looping. Both handle a "no-find" case.

1. The VBA equivalent of a normal function VLOOKUP with error-handling if the variable doesn't exist (INDEX/MATCH may be a better route than VLOOKUP, ie if your two columns A and B were in reverse order, or were far apart)

2. VBAs FIND method (matching a whole string in column A given I use the xlWhole argument)

   Sub Method1()
   Dim strSearch As String
   Dim strOut As String
   Dim bFailed As Boolean
   
   strSearch = "trees"
   
   On Error Resume Next
   strOut = Application.WorksheetFunction.VLookup(strSearch, Range("A:B"), 2, False)
   If Err.Number <> 0 Then bFailed = True
   On Error GoTo 0
   
   If Not bFailed Then
   MsgBox "corresponding value is " & vbNewLine & strOut
   Else
   MsgBox strSearch & " not found"
   End If
   End Sub
   
   Sub Method2()
       Dim rng1 As Range
       Dim strSearch As String
       strSearch = "trees"
       Set rng1 = Range("A:A").Find(strSearch, , xlValues, xlWhole)
       If Not rng1 Is Nothing Then
           MsgBox "Find has matched " & strSearch & vbNewLine & "corresponding cell is " & rng1.Offset(0, 1)
       Else
           MsgBox strSearch & " not found"
       End If
   End Sub
   

How do they achieve internally that you are able to pass something like x > 5 into a method?

The short answer is that they don't.

Any sort of logical operation on a numpy array returns a boolean array. (i.e. __gt__, __lt__, etc all return boolean arrays where the given condition is true).

E.g.

x = np.arange(9).reshape(3,3)
print x > 5

yields:

array([[False, False, False],
       [False, False, False],
       [ True,  True,  True]], dtype=bool)

This is the same reason why something like if x > 5: raises a ValueError if x is a numpy array. It's an array of True/False values, not a single value.

Furthermore, numpy arrays can be indexed by boolean arrays. E.g. x[x>5] yields [6 7 8], in this case.

Honestly, it's fairly rare that you actually need numpy.where but it just returns the indicies where a boolean array is True. Usually you can do what you need with simple boolean indexing.

a = sin²(?f/2) + cos f1 · cos f2 · sin²(??/2)

c = 2 · atan2( va, v(1-a) )

distance = R · c

where f is latitude, ? is longitude, R is earth’s radius (mean radius = 6,371km);

note that angles need to be in radians to pass to trig functions!

fun distanceInMeter(firstLocation: Location, secondLocation: Location): Double {
    val earthRadius = 6371000.0
    val deltaLatitudeDegree = (firstLocation.latitude - secondLocation.latitude) * Math.PI / 180f
    val deltaLongitudeDegree = (firstLocation.longitude - secondLocation.longitude) * Math.PI / 180f
    val a = sin(deltaLatitudeDegree / 2).pow(2) +
            cos(firstLocation.latitude * Math.PI / 180f) * cos(secondLocation.latitude * Math.PI / 180f) *
            sin(deltaLongitudeDegree / 2).pow(2)
    val c = 2f * atan2(sqrt(a), sqrt(1 - a))
    return earthRadius * c
}


data class Location(val latitude: Double, val longitude: Double)

$('#content').html('whatever');

Just use npm module config (more than 300000 downloads)

https://www.npmjs.com/package/config

Node-config organizes hierarchical configurations for your app deployments.

It lets you define a set of default parameters, and extend them for different deployment environments (development, qa, staging, production, etc.).

$ npm install config
$ mkdir config
$ vi config/default.json


{
      // Customer module configs
      "Customer": {
        "dbConfig": {
          "host": "localhost",
          "port": 5984,
          "dbName": "customers"
        },
        "credit": {
          "initialLimit": 100,
          // Set low for development
          "initialDays": 1
        }
      }
}



$ vi config/production.json

{
  "Customer": {
    "dbConfig": {
      "host": "prod-db-server"
    },
    "credit": {
      "initialDays": 30
    }
  }
}



$ vi index.js

var config = require('config');
//...
var dbConfig = config.get('Customer.dbConfig');
db.connect(dbConfig, ...);

if (config.has('optionalFeature.detail')) {
  var detail = config.get('optionalFeature.detail');
  //...
}


$ export NODE_ENV=production
$ node index.js

When you say you are forking a repository, you are basically creating a copy of the original repository under your GitHub ID in your GitHub account.

and

When you say you are cloning a repository, you are creating a local copy of the original repository in your system (PC/laptop) directly without having a copy in your GitHub account.

I managed to do this with a pretty simple bit of CSS. This does require that the error messages be siblings of the input they relate to, and that they have a class of error.

:focus ~ .error {
    display:none;
}

After meeting those two requirements, this will hide any error message related to a focused input field, something that I think angularjs should be doing anyway. Seems like an oversight.

The keyword for Oracle PL/SQL is "ELSIF" ( no extra "E"), not ELSEIF (yes, confusing and stupid)

declare
    var_number number;
begin
    var_number := 10;
    if var_number > 100 then
       dbms_output.put_line(var_number||' is greater than 100');
    elsif var_number < 100 then
       dbms_output.put_line(var_number||' is less than 100');
    else
       dbms_output.put_line(var_number||' is equal to 100');
    end if;
end;

Just use

plt.show()

This command tells the system to draw the plot in Pycharm.

Example:

plt.imshow(img.reshape((28, 28)))
plt.show()

I struggled with the same problem where I was trying to execute an update query like the same as you did-

@Modifying
@Transactional
@Query(value = "UPDATE SAMPLE_TABLE st SET st.status=:flag WHERE se.referenceNo in :ids")
public int updateStatus(@Param("flag")String flag, @Param("ids")List<String> references);

This will work if you have put @EnableTransactionManagement annotation on the main class. Spring 3.1 introduces the @EnableTransactionManagement annotation to be used in on @Configuration classes and enable transactional support.

Point one which is not the answer.
Even if you never program in it, I find it useful to know at least one assembler instruction set. This is part of the programmers never-ending quest to know more and therefore be better. Also useful when stepping into frameworks you don't have the source code to and having at least a rough idea what is going on. It also helps you to understand JavaByteCode and .Net IL as they are both similar to assembler.

To answer the question when you have a small amount of code or a large amount of time. Most useful for use in embedded chips, where low chip complexity and poor competition in compilers targeting these chips can tip the balance in favour of humans. Also for restricted devices you are often trading off code size/memory size/performance in a way that would be hard to instruct a compiler to do. e.g. I know this user action is not called often so I will have small code size and poor performance, but this other function that look similar is used every second so I will have a larger code size and faster performance. That is the sort of trade off a skilled assembly programmer can use.

I would also like to add there is a lot of middle ground where you can code in C compile and examine the Assembly produced, then either change you C code or tweak and maintain as assembly.

My friend works on micro controllers, currently chips for controlling small electric motors. He works in a combination of low level c and Assembly. He once told me of a good day at work where he reduced the main loop from 48 instructions to 43. He is also faced with choices like the code has grown to fill the 256k chip and the business is wanting a new feature, do you

1. Remove an existing feature
2. Reduce the size of some or all of the existing features maybe at the cost of performance.
3. Advocate moving to a larger chip with a higher cost, higher power consumption and larger form factor.

I would like to add as a commercial developer with quite a portfolio or languages, platforms, types of applications I have never once felt the need to dive into writing assembly. I have how ever always appreciated the knowledge I gained about it. And sometimes debugged into it.

I know I have far more answered the question "why should I learn assembler" but I feel it is a more important question then when is it faster.

so lets try once more You should be thinking about assembly

• working on low level operating system function
• Working on a compiler.
• Working on an extremely limited chip, embedded system etc

Remember to compare your assembly to compiler generated to see which is faster/smaller/better.

Collections.emptyList is immutable so there is a difference between the two versions so you have to consider users of the returned value.

Returning new ArrayList<Foo> always creates a new instance of the object so it has a very slight extra cost associated with it which may give you a reason to use Collections.emptyList. I like using emptyList just because it's more readable.

You can delete a file as follow:

File file = new File("your sdcard path is here which you want to delete");
file.delete();
if (file.exists()){
  file.getCanonicalFile().delete();
  if (file.exists()){
    deleteFile(file.getName());
  }
}

I belive the answer is:

echo date('Y-m-d H:i:s');

.toString() is available, or just add "" to the end of the int

var x = 3,
    toString = x.toString(),
    toConcat = x + "";

Angular is simply JavaScript at the core.

Use SQLCipher, it's an opensource extension for SQLite that provides transparent 256-bit AES encryption of database files. http://sqlcipher.net

Generally, you will get a lot of theoretical but one of the easiest ways to differentiate these two concepts is as follows:

In order to get a service, you need a service number. This service number is called a port. Simple as that.

For example, the HTTP as a service is running on port 80.

Now, many people can request the service and a connection from client-server has established. There will be a lot of connections. Each connection represent a client. In order to maintain each connection, the server creates a socket per connection to maintain its client.

C++20 offers a new way to achieve this by using std::source_location. This is currently accessible in gcc an clang as std::experimental::source_location with #include <experimental/source_location>.

The problem with macros like __LINE__ is that if you want to create for example a logging function that outputs the current line number along with a message, you always have to pass __LINE__ as a function argument, because it is expanded at the call site. Something like this:

void log(const std::string msg) {
    std::cout << __LINE__ << " " << msg << std::endl;
}

Will always output the line of the function declaration and not the line where log was actually called from. On the other hand, with std::source_location you can write something like this:

#include <experimental/source_location>
using std::experimental::source_location;

void log(const std::string msg, const source_location loc = source_location::current())
{
    std::cout << loc.line() << " " << msg << std::endl;
}

Here, loc is initialized with the line number pointing to the location where log was called. You can try it online here.

From the Jquery docs: you specify the async option to be false to get a synchronous Ajax request. Then your callback can set some data before your mother function proceeds.

Here's what your code would look like if changed as suggested:

beforecreate: function(node,targetNode,type,to) {
    jQuery.ajax({
         url:    url,
         success: function(result) {
                      if(result.isOk == false)
                          alert(result.message);
                  },
         async:   false
    });          
}

this is because $.ajax is the only request type that you can set the asynchronousity for

package net.schmizz.sshj.examples;

import net.schmizz.sshj.SSHClient;
import net.schmizz.sshj.sftp.SFTPClient;
import net.schmizz.sshj.xfer.FileSystemFile;

import java.io.File;
import java.io.IOException;

/** This example demonstrates uploading of a file over SFTP to the SSH server. */
public class SFTPUpload {

    public static void main(String[] args)
            throws IOException {
        final SSHClient ssh = new SSHClient();
        ssh.loadKnownHosts();
        ssh.connect("localhost");
        try {
            ssh.authPublickey(System.getProperty("user.name"));
            final String src = System.getProperty("user.home") + File.separator + "test_file";
            final SFTPClient sftp = ssh.newSFTPClient();
            try {
                sftp.put(new FileSystemFile(src), "/tmp");
            } finally {
                sftp.close();
            }
        } finally {
            ssh.disconnect();
        }
    }

}

This is my mix:

overflow-y: scroll;
height: 13em; // Initial height.
resize: vertical; // Allow user to change the vertical size.
max-height: 31em; // If you want to constrain the max size.

Define mappings for both behaviors, because both are useful!

• Completely clear the search buffer (e.g., pressing n for next match will not resume search)
• Retain search buffer, and toggle highlighting the search results on/off/on/... (e.g., pressing n will resume search, but highlighting will be based on current state of toggle)

" use double-Esc to completely clear the search buffer
nnoremap <silent> <Esc><Esc> :let @/ = ""<CR>
" use space to retain the search buffer and toggle highlighting off/on
nnoremap <silent> <Space> :set hlsearch!<CR>

This answer will do what you need, although usually you don't add specific usernames to sudoers. Instead, you have a group of sudoers and just add your user to that group when needed. This way you don't need to use visudo more than once when giving sudo permission to users.

If you're on Ubuntu, the group is most probably already set up and called admin:

$ sudo cat /etc/sudoers
#
# This file MUST be edited with the 'visudo' command as root.
#

...

# Members of the admin group may gain root privileges
%admin ALL=(ALL) ALL

# Allow members of group sudo to execute any command
%sudo   ALL=(ALL:ALL) ALL

# See sudoers(5) for more information on "#include" directives:

#includedir /etc/sudoers.d

On other distributions, like Arch and some others, it's usually called wheel and you may need to set it up: Arch Wiki

To give users in the wheel group full root privileges when they precede a command with "sudo", uncomment the following line: %wheel ALL=(ALL) ALL

Also note that on most systems visudo will read the EDITOR environment variable or default to using vi. So you can try to do EDITOR=vim visudo to use vim as the editor.

To add a user to the group you should run (as root):

# usermod -a -G groupname username

where groupname is your group (say, admin or wheel) and username is the username (say, john).

I got this error because i was calling "notifyItemInserted" twice by mistake.

I like Guffa's answer and since I can't comment I will provide the answer Udil's question here.

I needed something similar but I wanted certein logic in my token, I wanted to:

1. See the expiration of a token
2. Use a guid to mask validate (global application guid or user guid)
3. See if the token was provided for the purpose I created it (no reuse..)
4. See if the user I send the token to is the user that I am validating it for

Now points 1-3 are fixed length so it was easy, here is my code:

Here is my code to generate the token:

public string GenerateToken(string reason, MyUser user)
{
    byte[] _time     = BitConverter.GetBytes(DateTime.UtcNow.ToBinary());
    byte[] _key      = Guid.Parse(user.SecurityStamp).ToByteArray();
    byte[] _Id       = GetBytes(user.Id.ToString());
    byte[] _reason   = GetBytes(reason);
    byte[] data       = new byte[_time.Length + _key.Length + _reason.Length+_Id.Length];

    System.Buffer.BlockCopy(_time, 0, data, 0, _time.Length);
    System.Buffer.BlockCopy(_key , 0, data, _time.Length, _key.Length);
    System.Buffer.BlockCopy(_reason, 0, data, _time.Length + _key.Length, _reason.Length);
    System.Buffer.BlockCopy(_Id, 0, data, _time.Length + _key.Length + _reason.Length, _Id.Length);

    return Convert.ToBase64String(data.ToArray());
}

Here is my Code to take the generated token string and validate it:

public TokenValidation ValidateToken(string reason, MyUser user, string token)
{
    var result = new TokenValidation();
    byte[] data     = Convert.FromBase64String(token);
    byte[] _time     = data.Take(8).ToArray();
    byte[] _key      = data.Skip(8).Take(16).ToArray();
    byte[] _reason   = data.Skip(24).Take(2).ToArray();
    byte[] _Id       = data.Skip(26).ToArray();

    DateTime when = DateTime.FromBinary(BitConverter.ToInt64(_time, 0));
    if (when < DateTime.UtcNow.AddHours(-24))
    {
        result.Errors.Add( TokenValidationStatus.Expired);
    }
    
    Guid gKey = new Guid(_key);
    if (gKey.ToString() != user.SecurityStamp)
    {
        result.Errors.Add(TokenValidationStatus.WrongGuid);
    }

    if (reason != GetString(_reason))
    {
        result.Errors.Add(TokenValidationStatus.WrongPurpose);
    }

    if (user.Id.ToString() != GetString(_Id))
    {
        result.Errors.Add(TokenValidationStatus.WrongUser);
    }
    
    return result;
}

private static string GetString(byte[] reason) => Encoding.ASCII.GetString(reason);

private static byte[] GetBytes(string reason) => Encoding.ASCII.GetBytes(reason);

The TokenValidation class looks like this:

public class TokenValidation
{
    public bool Validated { get { return Errors.Count == 0; } }
    public readonly List<TokenValidationStatus> Errors = new List<TokenValidationStatus>();
}

public enum TokenValidationStatus
{
    Expired,
    WrongUser,
    WrongPurpose,
    WrongGuid
}

Now I have an easy way to validate a token, no Need to Keep it in a list for 24 hours or so. Here is my Good-Case Unit test:

private const string ResetPasswordTokenPurpose = "RP";
private const string ConfirmEmailTokenPurpose  = "EC";//change here change bit length for reason  section (2 per char)

[TestMethod]
public void GenerateTokenTest()
{
    MyUser user         = CreateTestUser("name");
    user.Id             = 123;
    user.SecurityStamp  = Guid.NewGuid().ToString();
    var token   = sit.GenerateToken(ConfirmEmailTokenPurpose, user);
    var validation    = sit.ValidateToken(ConfirmEmailTokenPurpose, user, token);
    Assert.IsTrue(validation.Validated,"Token validated for user 123");
}

One can adapt the code for other business cases easely.

Happy Coding

It's easy for disk file, but harder for Bitmap in memory.

System.Drawing.Bitmap bmp;
Image image;
...
MemoryStream ms = new MemoryStream();
bmp.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
ms.Position = 0;
BitmapImage bi = new BitmapImage();
bi.BeginInit();
bi.StreamSource = ms;
bi.EndInit();

image.Source = bi;

One can create an empty array, fill it (otherwise map will skip it) and then map indexes to values:

Array(8).fill().map((_, i) => i * i);

Useful differences:

• Use notify() if all your waiting threads are interchangeable (the order they wake up doesn't matter), or if you only ever have one waiting thread. A common example is a thread pool used to execute jobs from a queue--when a job is added, one of threads is notified to wake up, execute the next job and go back to sleep.

• Use notifyAll() for other cases where the waiting threads may have different purposes and should be able to run concurrently. An example is a maintenance operation on a shared resource, where multiple threads are waiting for the operation to complete before accessing the resource.

In SQL Server 2008, there is a DATE datetype (also a TIME datatype).

CAST(GetDate() as DATE)

or

declare @Dt as DATE = GetDate()

I use "e.getActionCommand().contains(CharSecuence s)", since I´m coming from an MVC context, and the Button is declared in the View class, but the actionPerformed call occurs in the controller.

public View() {
    ....
    buttonPlus = new Button("+");
    buttonMinus = new Button("-");
    ....
}

public void addController(ActionListener controller) {
    buttonPlus.addActionListener(controller);
    buttonMinus.addActionListener(controller);
}

My controller class implements ActionListener, and so, when overriding actionPerformed:

public void actionPerformed(ActionEvent e) {
    if(e.getActionCommand().contains("+")) {
        //do some action on the model
    } else if (e.getActionCommand().contains("-")) {
       //do some other action on the model
    }
}

I hope this other answer is also useful.

Dim row As DataRow
For Each row In dtDataTable.Rows
    Dim strDetail As String
    strDetail = row("Detail")
    Console.WriteLine("Processing Detail {0}", strDetail)
Next row

In a Windows command prompt, chdir or cd will print the full path of the current working directory in the console.

If we want to copy the path then we can use: cd | clip.

Based on @Mark Byers great answer, and following @Florent question, just to indicate that it will also work with 2 conditions on list of dics with more than 2 keys:

names = []
names.append({'first': 'Nil', 'last': 'Elliot', 'suffix': 'III'})
names.append({'first': 'Max', 'last': 'Sam', 'suffix': 'IX'})
names.append({'first': 'Anthony', 'last': 'Mark', 'suffix': 'IX'})

if not any(d['first'] == 'Anthony' and d['last'] == 'Mark' for d in names):

    print('Not exists!')
else:
    print('Exists!')

Result:

Exists!

Why not use document.documentMode only available under IE:

var doc = $window.document;
if (!!doc.documentMode)
{
  if (doc.documentMode === 10)
  {
    doc.documentElement.className += ' isIE isIE10';
  }
  else if (doc.documentMode === 11)
  {
    doc.documentElement.className += ' isIE isIE11';
  }
  // etc.
}

First store the table in a view, then select columns from that view into a new table.

// Create a table with abitrary columns for use with the example
System.Data.DataTable table = new System.Data.DataTable();
for (int i = 1; i <= 11; i++)
    table.Columns.Add("col" + i.ToString());

// Load the table with contrived data
for (int i = 0; i < 100; i++)
{
    System.Data.DataRow row = table.NewRow();
    for (int j = 0; j < 11; j++)
        row[j] = i.ToString() + ", " + j.ToString();
    table.Rows.Add(row);
}

// Create the DataView of the DataTable
System.Data.DataView view = new System.Data.DataView(table);
// Create a new DataTable from the DataView with just the columns desired - and in the order desired
System.Data.DataTable selected = view.ToTable("Selected", false, "col1", "col2", "col6", "col7", "col3");

Used the sample data to test this method I found: Create ADO.NET DataView showing only selected Columns

As of JDK6U18 following are configurations for the Heap Size.

In the Client JVM, the default Java heap configuration has been modified to improve the performance of today's rich client applications. Initial and maximum heap sizes are larger and settings related to generational garbage collection are better tuned.

The default maximum heap size is half of the physical memory up to a physical memory size of 192 megabytes and otherwise one fourth of the physical memory up to a physical memory size of 1 gigabyte. For example, if your machine has 128 megabytes of physical memory, then the maximum heap size is 64 megabytes, and greater than or equal to 1 gigabyte of physical memory results in a maximum heap size of 256 megabytes. The maximum heap size is not actually used by the JVM unless your program creates enough objects to require it. A much smaller amount, termed the initial heap size, is allocated during JVM initialization. This amount is at least 8 megabytes and otherwise 1/64 of physical memory up to a physical memory size of 1 gigabyte.

For the block element not occupy the whole line, set it's width to something small and the white-space:nowrap

label
{
    width:10px;
    display:block;
    white-space:nowrap;
}

SELECT DATABASEPROPERTYEX('DBName', 'Collation') SQLCollation;

Where DBName is your database name.

I normally set paths in

~/.bashrc

However for Java, I followed instructions at https://askubuntu.com/questions/55848/how-do-i-install-oracle-java-jdk-7

and it was sufficient for me.

you can also define multiple java_home's and have only one of them active (rest commented).

suppose in your bashrc file, you have

export JAVA_HOME=......jdk1.7

#export JAVA_HOME=......jdk1.8

notice 1.8 is commented. Once you do

source ~/.bashrc

jdk1.7 will be in path.

you can switch them fairly easily this way. There are other more permanent solutions too. The link I posted has that info.

it may be that your firewalls are preventing you from accessing the localhost's webserver.
Put the IP addresses of both of your computers' internet security antivirus network security as safe IP addresses if required.
How to find the IP address of your windows PC: Start > (Run) type in: cmd (Enter)
(This opens the black box command prompt)
type in ipconfig (Enter)
Let's say your Apache or IIS webserver is installed on your PC: 192.168.0.3
and you want to access your webserver with your laptop. (laptop's IP is 192.168.0.5)
On your PC you type in: http://localhost/ inside your Firefox or Internet Eplorer browser to access your data on your webserver.
On your laptop you type in http://192.168.0.3/ to access your webserver on your PC.

For all these things to work you need have installed a webserver correctly (e.g. IIS, Apache, XAMP, WAMP etc).

If it does not work, try to ping your PC from your laptop:
Open up command propmt on your laptop: Start > cmd (Enter)
ping 192.168.1.3 (Enter)
If the pinging fails, then firewalls are blocking your connection or your network cabling is faulty. Restart your modem or network switch and your machines.
Close programs such as chat programs that are using your ports.
You can also try a diffrent port number: http:192.168.0.3:80 or http:192.168.0.3:81 or any random number at the end

Swift is worry that your case statement is not covering all cases, to fix it you need to create a default case:

do {
    let sandwich = try makeMeSandwich(kitchen)
    print("i eat it \(sandwich)")
} catch SandwichError.NotMe {
    print("Not me error")
} catch SandwichError.DoItYourself {
    print("do it error")
} catch Default {
    print("Another Error")
}

history -c will clear all histories.

Another option is using eval and parse, as in

d = 5
for (i in 1:10){
     eval(parse(text = paste('a', 1:10, ' = d + rnorm(3)', sep='')[i]))
}

1. Create SDK folder at \Android\Sdk
2. Close any project which is already open in Android studio

Android Studio setup wizard will appear and perform the needed installation.

can't you just subset the columns in either df first?

[i for i in df.columns if i not in df2.columns]

dfNew = merge(df **[i for i in df.columns if i not in df2.columns]**, df2, left_index=True, right_index=True, how='outer')

This looks like a behavior difference in the handling of \s between grep 2.5 and newer versions (a bug in old grep?). I confirm your result with grep 2.5.4, but all four of your greps do work when using grep 2.6.3 (Ubuntu 10.10).

Note:

GNU grep 2.5.4
echo "foo bar" | grep "\s"
   (doesn't match)

whereas

GNU grep 2.6.3
echo "foo bar" | grep "\s"
foo bar

Probably less trouble (as \s is not documented):

Both GNU greps
echo "foo bar" | grep "[[:space:]]"
foo bar

My advice is to avoid using \s ... use [ \t]* or [[:space:]] or something like it instead.

I use this, because it's very easy:

if [ `LANG=C type example 2>/dev/null|wc -l` = 1 ];then echo exists;else echo "not exists";fi

or

if [ `LANG=C type example 2>/dev/null|wc -l` = 1 ];then
echo exists
else echo "not exists"
fi

It uses shell builtins and programs' echo status to standard output and nothing to standard error. On the other hand, if a command is not found, it echos status only to standard error.

if you got troubles with windows cmd command and .bat just escape percents like that

git show -s --format=%%ct

The % character has a special meaning for command line parameters and FOR parameters. To treat a percent as a regular character, double it: %%

Syntax : Escape Characters, Delimiters and Quotes

This should work

return RedirectToAction("actionName", "controllerName", null);

Adding this here as it might help someone. I was having problems with Android showing the popup and invalid certificate error.

We have a Comodo Extended Validation certificate and we received the zip file that contained 4 files:

• AddTrustExternalCARoot.crt
• COMODORSAAddTrustCA.crt
• COMODORSAExtendedValidationSecureServerCA.crt
• www_mydomain_com.crt

I concatenated them together all on one line like so:

cat www_mydomain_com.crt COMODORSAExtendedValidationSecureServerCA.crt COMODORSAAddTrustCA.crt AddTrustExternalCARoot.crt >www.mydomain.com.ev-ssl-bundle.crt

Then I used that bundle file as my ssl_certificate_key in nginx. That's it, works now.

Inspired by this gist: https://gist.github.com/ipedrazas/6d6c31144636d586dcc3

It entirely depends upon the Certificate Authority who issuing a certificate.

As far as Let's Encrypt CA, they wont issue TLS certificate on public IP address. https://community.letsencrypt.org/t/certificate-for-public-ip-without-domain-name/6082

To know your Certificate authority , you can execute following command and look for an entry marked below.

curl -v -u <username>:<password> "https://IPaddress/.."

I would be careful with setting the display of the element to block. Different elements have the standard display as different things. For example setting display to block for a table row in firefox causes the width of the cells to be incorrect.

Is the name of the element actually test1. I know that .NET can add extra things onto the start or end. The best way to find out if your selector is working properly is by doing this.

alert($('#text1').length);

You might just need to remove the visibility attribute

$('#text1').removeAttr('visibility');

In Swift 2.0 and Xcode 7.2:

let pi:Double = 3.14159265358979
String(format:"%.2f", pi)

Example:

Below is how I got this working.

The Key point was: I needed to use the ViewModel associated with the view in order for the runtime to be able to resolve the object in the request.

[I know that that there is a way to bind an object other than the default ViewModel object but ended up simply populating the necessary properties for my needs as I could not get it to work]

[HttpPost]  
  public ActionResult GetDataForInvoiceNumber(MyViewModel myViewModel)  
  {            
     var invoiceNumberQueryResult = _viewModelBuilder.HydrateMyViewModelGivenInvoiceDetail(myViewModel.InvoiceNumber, myViewModel.SelectedCompanyCode);
     return Json(invoiceNumberQueryResult, JsonRequestBehavior.DenyGet);
  }

The JQuery script used to call this action method:

var requestData = {
         InvoiceNumber: $.trim(this.value),
         SelectedCompanyCode: $.trim($('#SelectedCompanyCode').val())
      };


      $.ajax({
         url: '/en/myController/GetDataForInvoiceNumber',
         type: 'POST',
         data: JSON.stringify(requestData),
         dataType: 'json',
         contentType: 'application/json; charset=utf-8',
         error: function (xhr) {
            alert('Error: ' + xhr.statusText);
         },
         success: function (result) {
            CheckIfInvoiceFound(result);
         },
         async: true,
         processData: false
      });

Read file contents into a variable:

for /f "delims=" %%x in (version.txt) do set Build=%%x

or

set /p Build=<version.txt

Both will act the same with only a single line in the file, for more lines the for variant will put the last line into the variable, while set /p will use the first.

Using the variable – just like any other environment variable – it is one, after all:

%Build%

So to check for existence:

if exist \\fileserver\myapp\releasedocs\%Build%.doc ...

Although it may well be that no UNC paths are allowed there. Can't test this right now but keep this in mind.

File manipulation isn't normally done by Bash, but by programs invoked by Bash, e.g.:

perl -pi -e 's/abc/XYZ/g' /tmp/file.txt

The -i flag tells it to do an in-place replacement.

See man perlrun for more details, including how to take a backup of the original file.

Varying is an alias for varchar, so no difference, see documentation :)

The notations varchar(n) and char(n) are aliases for character varying(n) and character(n), respectively. character without length specifier is equivalent to character(1). If character varying is used without length specifier, the type accepts strings of any size. The latter is a PostgreSQL extension.

angular.module('formComponents', [])
  .directive('formInput', function() {
    return {
        restrict: 'E',
        compile: function(element, attrs) {
            var type = attrs.type || 'text';
            var required = attrs.hasOwnProperty('required') ? "required='required'" : "";
            var htmlText = '<div class="control-group">' +
                '<label class="control-label" for="' + attrs.formId + '">' + attrs.label + '</label>' +
                    '<div class="controls">' +
                    '<input type="' + type + '" class="input-xlarge" id="' + attrs.formId + '" name="' + attrs.formId + '" ' + required + '>' +
                    '</div>' +
                '</div>';
            element.replaceWith(htmlText);
        }
    };
})

My suggestion would be to get the book Programming From Ground Up:

http://nongnu.askapache.com/pgubook/ProgrammingGroundUp-1-0-booksize.pdf

That is a very good starting point for getting into assembler programming under linux and it explains a lot of the basics you need to understand to get started.

Use SimpleDateFormat class. Take a look on its javadoc: it explains how to use format switches.

You can also use create_function to create a function as a variable and pass it around. Though, I like the feeling of anonymous functions better. Go zombat.

There is another way to have multiple dataSources by using @EnableAutoConfiguration and application.properties.

Basically put multiple dataSource configuration info on application.properties and generate default setup (dataSource and entityManagerFactory) automatically for first dataSource by @EnableAutoConfiguration. But for next dataSource, create dataSource, entityManagerFactory and transactionManager all manually by the info from property file.

Below is my example to setup two dataSources. First dataSource is setup by @EnableAutoConfiguration which can be assigned only for one configuration, not multiple. And that will generate 'transactionManager' by DataSourceTransactionManager, that looks default transactionManager generated by the annotation. However I have seen the transaction not beginning issue on the thread from scheduled thread pool only for the default DataSourceTransactionManager and also when there are multiple transaction managers. So I create transactionManager manually by JpaTransactionManager also for the first dataSource with assigning 'transactionManager' bean name and default entityManagerFactory. That JpaTransactionManager for first dataSource surely resolves the weird transaction issue on the thread from ScheduledThreadPool.

Update for Spring Boot 1.3.0.RELEASE

I found my previous configuration with @EnableAutoConfiguration for default dataSource has issue on finding entityManagerFactory with Spring Boot 1.3 version. Maybe default entityManagerFactory is not generated by @EnableAutoConfiguration, once after I introduce my own transactionManager. So now I create entityManagerFactory by myself. So I don't need to use @EntityScan. So it looks I'm getting more and more out of the setup by @EnableAutoConfiguration.

Second dataSource is setup without @EnableAutoConfiguration and create 'anotherTransactionManager' by manual way.

Since there are multiple transactionManager extends from PlatformTransactionManager, we should specify which transactionManager to use on each @Transactional annotation

Default Repository Config

@Configuration
@EnableTransactionManagement
@EnableAutoConfiguration
@EnableJpaRepositories(
        entityManagerFactoryRef = "entityManagerFactory",
        transactionManagerRef = "transactionManager",
        basePackages = {"com.mysource.repository"})
public class RepositoryConfig {
    @Autowired
    JpaVendorAdapter jpaVendorAdapter;

    @Autowired
    DataSource dataSource;

    @Bean(name = "entityManager")
    public EntityManager entityManager() {
        return entityManagerFactory().createEntityManager();
    }

    @Primary
    @Bean(name = "entityManagerFactory")
    public EntityManagerFactory entityManagerFactory() {
        LocalContainerEntityManagerFactoryBean emf = new LocalContainerEntityManagerFactoryBean();
        emf.setDataSource(dataSource);
        emf.setJpaVendorAdapter(jpaVendorAdapter);
        emf.setPackagesToScan("com.mysource.model");
        emf.setPersistenceUnitName("default");   // <- giving 'default' as name
        emf.afterPropertiesSet();
        return emf.getObject();
    }

    @Bean(name = "transactionManager")
    public PlatformTransactionManager transactionManager() {
        JpaTransactionManager tm = new JpaTransactionManager();
        tm.setEntityManagerFactory(entityManagerFactory());
        return tm;
    }
}

Another Repository Config

@Configuration
@EnableTransactionManagement
@EnableJpaRepositories(
        entityManagerFactoryRef = "anotherEntityManagerFactory",
        transactionManagerRef = "anotherTransactionManager",
        basePackages = {"com.mysource.anothersource.repository"})
public class AnotherRepositoryConfig {
    @Autowired
    JpaVendorAdapter jpaVendorAdapter;

    @Value("${another.datasource.url}")
    private String databaseUrl;

    @Value("${another.datasource.username}")
    private String username;

    @Value("${another.datasource.password}")
    private String password;

    @Value("${another.dataource.driverClassName}")

@Service("mainService")
@Transactional("transactionManager")
public class DefaultDataSourceServiceImpl implements DefaultDataSourceService

I used spread operator and some to check least one element in the array passes the test.

I share for whom concern.

var checked = [...document.getElementsByName("gender")].some(c=>c.checked);_x000D_
console.log(checked);

<input type="radio" name="gender" checked value="Male" />_x000D_
<input type="radio" name="gender"  value="Female" / >

Use global namespace or global object like Constants.

var Constants = {};

And using defineObject write function which will add all properties to that object and assign value to it.

function createConstant (prop, value) {
    Object.defineProperty(Constants , prop, {
      value: value,
      writable: false
   });
};

just a matter of taste but if you prefer accessing the variable or function directly like this:

<div id="playlist-icon" back-img="playlist.icon">

instead of interpolating like this:

<div id="playlist-icon" back-img="{{playlist.icon}}">

then you can define the directive a bit differently with scope.$watch which will do $parse on the attribute

angular.module('myApp', [])
.directive('bgImage', function(){

    return function(scope, element, attrs) {
        scope.$watch(attrs.bgImage, function(value) {
            element.css({
                'background-image': 'url(' + value +')',
                'background-size' : 'cover'
            });
        });
    };
})

there is more background on this here: AngularJS : Difference between the $observe and $watch methods

To trigger an enter keypress, I had to modify @ebynum response, specifically, using the keyCode property.

e = $.Event('keyup');
e.keyCode= 13; // enter
$('input').trigger(e);

From Python 2.5 onwards you can do:

value = b if a > 10 else c

Previously you would have to do something like the following, although the semantics isn't identical as the short circuiting effect is lost:

value = [c, b][a > 10]

There's also another hack using 'and ... or' but it's best to not use it as it has an undesirable behaviour in some situations that can lead to a hard to find bug. I won't even write the hack here as I think it's best not to use it, but you can read about it on Wikipedia if you want.

This is how you can do it-

HTML-

<div style="overflow:hidden; height:100%">
     <div style="float:left">a<br>b</div>
     <table cellpadding="0" cellspacing="0" style="height:100%;">     
          <tr><td>This is the content of a table that takes 100% height</td></tr>  
      </table>
 </div>

CSS-

html,body
{
    height:100%;
    background-color:grey;
}
table
{
    background-color:yellow;
}

See the DEMO

Update: Well, if you are not looking for applying 100% height to your parent containers, then here is a jQuery solution that should help you-

Demo-using jQuery

Script-

 $(document).ready(function(){
    var b= $(window).height(); //gets the window's height, change the selector if you are looking for height relative to some other element
    $("#tab").css("height",b);
});

One thing I would add here is that the at function on a dataframe is much faster particularly if you are doing a lot of assignments of individual (not slice) values.

df.at[index, 'col_name'] = x

In my experience I have gotten a 20x speedup. Here is a write up that is Spanish but still gives an impression of what's going on.

for listener support no services you can use the following command to set local_listener paramter in your spfile use your listener port and server ip address

alter system set local_listener='(DESCRIPTION=(ADDRESS=(PROTOCOL=tcp)(HOST=192.168.1.101)(PORT=1520)))' sid='testdb' scope=spfile;

Completing the answer:

String selectedOption = new Select(driver.findElement(By.xpath("Type the xpath of the drop-down element"))).getFirstSelectedOption().getText();

Assert.assertEquals("Please select any option...", selectedOption);

In PySpark you can use a dataframe and set header as True:

df = spark.read.csv(dataPath, header=True)

@Redu's solution is a good solution

arrOfObj.map(o => o.isActive = true;) but Array.map still counts as looping through all items.

if you absolutely don't want to have any looping here's a dirty hack :

Object.defineProperty(Object.prototype, "isActive",{
  value: true,
  writable: true,
  configurable: true,
  enumerable: true
});

my advice is not to use it carefully though, it will patch absolutely all javascript Objects (Date, Array, Number, String or any other that inherit Object ) which is really bad practice...

You can pass the element into the function <input type="button" value="mybutton1" onclick="dosomething(this)">test by passing this. Then in the function you can access the value like this:

function dosomething(element) {
  console.log(element.value);
}

Your second delegate is not a rewrite of the first in anonymous delegate (rather than lambda) format. Look at your conditions.

First:

x.ID == packageId || x.Parent.ID == packageId || x.Parent.Parent.ID == packageId

Second:

(x.ID == packageId) || (x.Parent != null && x.Parent.ID == packageId) || 
(x.Parent != null && x.Parent.Parent != null && x.Parent.Parent.ID == packageId)

The call to the lambda would throw an exception for any x where the ID doesn't match and either the parent is null or doesn't match and the grandparent is null. Copy the null checks into the lambda and it should work correctly.

Edit after Comment to Question

If your original object is not a List<T>, then we have no way of knowing what the return type of FindAll() is, and whether or not this implements the IQueryable interface. If it does, then that likely explains the discrepancy. Because lambdas can be converted at compile time into an Expression<Func<T>> but anonymous delegates cannot, then you may be using the implementation of IQueryable when using the lambda version but LINQ-to-Objects when using the anonymous delegate version.

This would also explain why your lambda is not causing a NullReferenceException. If you were to pass that lambda expression to something that implements IEnumerable<T> but not IQueryable<T>, runtime evaluation of the lambda (which is no different from other methods, anonymous or not) would throw a NullReferenceException the first time it encountered an object where ID was not equal to the target and the parent or grandparent was null.

Added 3/16/2011 8:29AM EDT

Consider the following simple example:

IQueryable<MyObject> source = ...; // some object that implements IQueryable<MyObject>

var anonymousMethod =  source.Where(delegate(MyObject o) { return o.Name == "Adam"; });    
var expressionLambda = source.Where(o => o.Name == "Adam");

These two methods produce entirely different results.

The first query is the simple version. The anonymous method results in a delegate that's then passed to the IEnumerable<MyObject>.Where extension method, where the entire contents of source will be checked (manually in memory using ordinary compiled code) against your delegate. In other words, if you're familiar with iterator blocks in C#, it's something like doing this:

public IEnumerable<MyObject> MyWhere(IEnumerable<MyObject> dataSource, Func<MyObject, bool> predicate)
{
    foreach(MyObject item in dataSource)
    {
        if(predicate(item)) yield return item;
    }
}

The salient point here is that you're actually performing your filtering in memory on the client side. For example, if your source were some SQL ORM, there would be no WHERE clause in the query; the entire result set would be brought back to the client and filtered there.

The second query, which uses a lambda expression, is converted to an Expression<Func<MyObject, bool>> and uses the IQueryable<MyObject>.Where() extension method. This results in an object that is also typed as IQueryable<MyObject>. All of this works by then passing the expression to the underlying provider. This is why you aren't getting a NullReferenceException. It's entirely up to the query provider how to translate the expression (which, rather than being an actual compiled function that it can just call, is a representation of the logic of the expression using objects) into something it can use.

An easy way to see the distinction (or, at least, that there is) a distinction, would be to put a call to AsEnumerable() before your call to Where in the lambda version. This will force your code to use LINQ-to-Objects (meaning it operates on IEnumerable<T> like the anonymous delegate version, not IQueryable<T> like the lambda version currently does), and you'll get the exceptions as expected.

TL;DR Version

The long and the short of it is that your lambda expression is being translated into some kind of query against your data source, whereas the anonymous method version is evaluating the entire data source in memory. Whatever is doing the translating of your lambda into a query is not representing the logic that you're expecting, which is why it isn't producing the results you're expecting.

std::istringstream ss(thestring);
ss >> thevalue;

To be fully correct you'll want to check the error flags.

json_decode() is used to decode a json string to an array/data object. json_encode() creates a json string from an array or data. You are using the wrong function my friend, try json_encode();

Multiply the value you want to insert (ex. 2.99) by 100

Then insert the division by 100 of the result adding .01 to the end:

299.01/100

The usual trick is to make the image itself part of a link instead of a button. Then, you bind the "click" event with a custom handler.

Frameworks like Jquery-UI or Bootstrap does this out of the box. Using one of them may ease a lot the whole application conception by the way.

Suppose you want to write that in the same file, you can do as follows:

Set-Content -Path "C:\temp\Newtext.txt" -Value (get-content -Path "c:\Temp\Newtext.txt" | Select-String -Pattern 'H\|159' -NotMatch)

We encountered this issue and discovered that the error was being thrown when using (IE in our case) the browser logged in as the process account, then changing the session log in through the application (SharePoint). I believe this scenario passes two authentication schemes:

1. Negotiate
2. NTLM

The application hosted an *.asmx web service, that was being called on a load balanced server, initiating a web service call to itself using a WCF-like .NET3.5 binding.

Code that was used to call the web service:

public class WebServiceClient<T> : IDisposable
{
    private readonly T _channel;
    private readonly IClientChannel _clientChannel;

    public WebServiceClient(string url)
        : this(url, null)
    {
    }
    /// <summary>
    /// Use action to change some of the connection properties before creating the channel
    /// </summary>
    public WebServiceClient(string url,
         Action<CustomBinding, HttpTransportBindingElement, EndpointAddress, ChannelFactory> init)
    {
        var binding = new CustomBinding();
        binding.Elements.Add(
            new TextMessageEncodingBindingElement(MessageVersion.Soap12, Encoding.UTF8));
        var transport = url.StartsWith("https", StringComparison.InvariantCultureIgnoreCase)
                            ? new HttpsTransportBindingElement()
                            : new HttpTransportBindingElement();
        transport.AuthenticationScheme = System.Net.AuthenticationSchemes.Ntlm;
        binding.Elements.Add(transport);

        var address = new EndpointAddress(url);

        var factory = new ChannelFactory<T>(binding, address);
        factory.Credentials.Windows.AllowedImpersonationLevel = System.Security.Principal.TokenImpersonationLevel.Impersonation;

        if (init != null)
        {
            init(binding, transport, address, factory);
        }

        this._clientChannel = (IClientChannel)factory.CreateChannel();
        this._channel = (T)this._clientChannel;
    }

    /// <summary>
    /// Use this property to call service methods
    /// </summary>
    public T Channel
    {
        get { return this._channel; }
    }
    /// <summary>
    /// Use this porperty when working with
    /// Session or Cookies
    /// </summary>
    public IClientChannel ClientChannel
    {
        get { return this._clientChannel; }
    }

    public void Dispose()
    {
        this._clientChannel.Dispose();
    }
}

We discovered that if the session credential was the same as the browser's process account, then just NTLM was used and the call was successful. Otherwise it would result in this captured exception:

The HTTP request is unauthorized with client authentication scheme 'Ntlm'. The authentication header received from the server was 'Negotiate,NTLM'.

In the end, I am fairly certain that one of the authentication schemes would pass authentication while the other wouldn't, because it was not granted appropriate access.

My code structure using is as shown below

-.env
-app.js
-build
-src
   |-modules
        |-users
            |-controller
                  |-userController.js

I have required .env at the top of my app.js

require('dotenv').config();
import express = require('express');
import bodyParser from 'body-parser';
import mongoose = require('mongoose');

The process.env.PORT works in my app.listen function. However, on my userController file not sure how this is happening but my problem was I was getting the secretKey value and type as string when I checked using console.log() but getting undefined when trying it on jwt.sign() e.g.

console.log('Type: '+ process.env.ACCESS_TOKEN_SECRET)
console.log(process.env.ACCESS_TOKEN_SECRET)

Result:

string
secret

jwt.sign giving error

let accessToken = jwt.sign(userObj, process.env.ACCESS_TOKEN_SECRET); //not working 

Error was

    Argument of type 'string | undefined' is not assignable to parameter of type 'Secret'.
  Type 'undefined' is not assignable to type 'Secret'.

My Solution: After reading the documentation. I required the env again in my file( which I probably should have in the first place ) and saved it to variable 'environment'

let environment = require('dotenv').config();

console logging environment this gives:

{
parsed: {
    DB_HOST: 'localhost',
    DB_USER: 'root',
    DB_PASS: 'pass',
    PORT: '3000',
    ACCESS_TOKEN_SECRET: 'secretKey',
  }
}

Using it on jwt.sign not works

let accessToken = jwt.sign(userObj, environment.parsed.ACCESS_TOKEN_SECRET);

Hope this helps, I was stuck on it for hours. Please feel free to add anything to my answer which may help explain more on this.

You can use "translateX(-100%)" and "text-align: right" if your absolute element is "display: inline-block"

<div class="box">
<div class="absolute-right"></div>
</div>

<style type="text/css">
.box{
    text-align: right;
}
.absolute-right{
    display: inline-block;
    position: absolute;
}

/*The magic:*/
.absolute-right{
-moz-transform: translateX(-100%);
-ms-transform: translateX(-100%);
-webkit-transform: translateX(-100%);
-o-transform: translateX(-100%);
transform: translateX(-100%);
}
</style>

You will get absolute-element aligned to the right relative its parent

Use element.innerHTML="some \\\\n some";.

The dat file has some lines of extra information before the actual data. Skip them with the skip argument:

read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
           header=TRUE, skip=3)

An easy way to check this if you are unfamiliar with the dataset is to first use readLines to check a few lines, as below:

readLines("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat", 
          n=10)
# [1] "Ozone data from CZ03 2009"   "Local time: GMT + 0"        
# [3] ""                            "Date        Hour      Value"
# [5] "01.01.2009 00:00       34.3" "01.01.2009 01:00       31.9"
# [7] "01.01.2009 02:00       29.9" "01.01.2009 03:00       28.5"
# [9] "01.01.2009 04:00       32.9" "01.01.2009 05:00       20.5"

Here, we can see that the actual data starts at [4], so we know to skip the first three lines.

Update

If you really only wanted the Value column, you could do that by:

as.vector(
    read.table("http://www.nilu.no/projects/ccc/onlinedata/ozone/CZ03_2009.dat",
               header=TRUE, skip=3)$Value)

Again, readLines is useful for helping us figure out the actual name of the columns we will be importing.

But I don't see much advantage to doing that over reading the whole dataset in and extracting later.

There is a good solution

if (AllocConsole() == 0)
{
    // Handle error here. Use ::GetLastError() to get the error.
}

// Redirect CRT standard input, output and error handles to the console window.
FILE * pNewStdout = nullptr;
FILE * pNewStderr = nullptr;
FILE * pNewStdin = nullptr;

::freopen_s(&pNewStdout, "CONOUT$", "w", stdout);
::freopen_s(&pNewStderr, "CONOUT$", "w", stderr);
::freopen_s(&pNewStdin, "CONIN$", "r", stdin);

// Clear the error state for all of the C++ standard streams. Attempting to accessing the streams before they refer
// to a valid target causes the stream to enter an error state. Clearing the error state will fix this problem,
// which seems to occur in newer version of Visual Studio even when the console has not been read from or written
// to yet.
std::cout.clear();
std::cerr.clear();
std::cin.clear();

std::wcout.clear();
std::wcerr.clear();
std::wcin.clear();

With the help of the of Guido mail provided by @kindall, we can understand the standard import process as trying to find the module in each member of sys.path, and file as the result of this lookup (more details in PyMOTW Modules and Imports.). So if the module is located in an absolute path in sys.path the result is absolute, but if it is located in a relative path in sys.path the result is relative.

Now the site.py startup file takes care of delivering only absolute path in sys.path, except the initial '', so if you don't change it by other means than setting the PYTHONPATH (whose path are also made absolute, before prefixing sys.path), you will get always an absolute path, but when the module is accessed through the current directory.

Now if you trick sys.path in a funny way you can get anything.

As example if you have a sample module foo.py in /tmp/ with the code:

import sys
print(sys.path)
print (__file__)

If you go in /tmp you get:

>>> import foo
['', '/tmp', '/usr/lib/python3.3', ...]
./foo.py

When in in /home/user, if you add /tmp your PYTHONPATH you get:

>>> import foo
['', '/tmp', '/usr/lib/python3.3', ...]
/tmp/foo.py

Even if you add ../../tmp, it will be normalized and the result is the same.

But if instead of using PYTHONPATH you use directly some funny path you get a result as funny as the cause.

>>> import sys
>>> sys.path.append('../../tmp')
>>> import foo
['', '/usr/lib/python3.3', .... , '../../tmp']
../../tmp/foo.py

Guido explains in the above cited thread, why python do not try to transform all entries in absolute paths:

we don't want to have to call getpwd() on every import .... getpwd() is relatively slow and can sometimes fail outright,

So your path is used as it is.

There is an HTTP header you can set that will force IE8 to use IE7-compatibility mode.

As you are using Excel you do not need VBA to achieve this, you can simply use the built in "Clean()" function, this removes carriage returns, line feeds etc e.g:

=Clean(MyString)

Both certificates should exist prior to the connection. They're usually created by Certification Authorities (not necessarily the same). (There are alternative cases where verification can be done differently, but some verification will need to be made.)

The server certificate should be created by a CA that the client trusts (and following the naming conventions defined in RFC 6125).

The client certificate should be created by a CA that the server trusts.

It's up to each party to choose what it trusts.

There are online CA tools that will allow you to apply for a certificate within your browser and get it installed there once the CA has issued it. They need not be on the server that requests client-certificate authentication.

The certificate distribution and trust management is the role of the Public Key Infrastructure (PKI), implemented via the CAs. The SSL/TLS client and servers and then merely users of that PKI.

When the client connects to a server that requests client-certificate authentication, the server sends a list of CAs it's willing to accept as part of the client-certificate request. The client is then able to send its client certificate, if it wishes to and a suitable one is available.

The main advantages of client-certificate authentication are:

• The private information (the private key) is never sent to the server. The client doesn't let its secret out at all during the authentication.
• A server that doesn't know a user with that certificate can still authenticate that user, provided it trusts the CA that issued the certificate (and that the certificate is valid). This is very similar to the way passports are used: you may have never met a person showing you a passport, but because you trust the issuing authority, you're able to link the identity to the person.

You may be interested in Advantages of client certificates for client authentication? (on Security.SE).

If you are doing any kind of array/collection manipulation or inspection I highly recommend using Underscore.js. It's small, well-tested and will save you days/weeks/years of javascript headache. Here is its keys function:

Keys

Retrieve all the names of the object's properties.

_.keys({one : 1, two : 2, three : 3});
=> ["one", "two", "three"]

It's because you have:

def readTTable(fname):
    try:

without a matching except block after the try: block. Every try must have at least one matching except.

I'm quite sure you won't get this 32Bit DLL working in Office 64Bit. The DLL needs to be updated by the author to be compatible with 64Bit versions of Office.

The code changes you have found and supplied in the question are used to convert calls to APIs that have already been rewritten for Office 64Bit. (Most Windows APIs have been updated.)

From: http://technet.microsoft.com/en-us/library/ee681792.aspx:

"ActiveX controls and add-in (COM) DLLs (dynamic link libraries) that were written for 32-bit Office will not work in a 64-bit process."

Edit: Further to your comment, I've tried the 64Bit DLL version on Win 8 64Bit with Office 2010 64Bit. Since you are using User Defined Functions called from the Excel worksheet you are not able to see the error thrown by Excel and just end up with the #VALUE returned.

If we create a custom procedure within VBA and try one of the DLL functions we see the exact error thrown. I tried a simple function of swe_day_of_week which just has a time as an input and I get the error Run-time error '48' File not found: swedll32.dll.

Now I have the 64Bit DLL you supplied in the correct locations so it should be found which suggests it has dependencies which cannot be located as per https://stackoverflow.com/a/8607250/1733206

I've got all the .NET frameworks installed which would be my first guess, so without further information from the author it might be difficult to find the problem.

Edit2: And after a bit more investigating it appears the 64Bit version you have supplied is actually a 32Bit version. Hence the error message on the 64Bit Office. You can check this by trying to access the '64Bit' version in Office 32Bit.

Answer

You have multiple options:

1. background-size: 100% 100%; - image gets stretched (aspect ratio may be preserved, depending on browser)
2. background-size: contain; - image is stretched without cutting it while preserving aspect ratio
3. background-size: cover; - image is completely covering the element while preserving aspect ratio (image can be cut off)

        for (Entity entity : entitys) {
            if (Integer.toString(entity.getId()).equals(rowKey)) return entity;

        return null;

The value of the match attribute of the <xsl:template> instruction must be a match pattern.

Match patterns form a subset of the set of all possible XPath expressions. The first, natural, limitation is that a match pattern must select a set of nodes. There are also other limitations. In particular, reverse axes are not allowed in the location steps (but can be specified within the predicates). Also, no variable or parameter references are allowed in XSLT 1.0, but using these is legal in XSLT 2.x.

/ in XPath denotes the root or document node. In XPath 2.0 (and hence XSLT 2.x) this can also be written as document-node().

A match pattern can contain the // abbreviation.

Examples of match patterns:

<xsl:template match="table">

can be applied on any element named table.

<xsl:template match="x/y">

can be applied on any element named y whose parent is an element named x.

<xsl:template match="*">

can be applied to any element.

<xsl:template match="/*">

can be applied only to the top element of an XML document.

<xsl:template match="@*">

can be applied to any attribute.

<xsl:template match="text()">

can be applied to any text node.

<xsl:template match="comment()">

can be applied to any comment node.

<xsl:template match="processing-instruction()">

can be applied to any processing instruction node.

<xsl:template match="node()">

can be applied to any node: element, text, comment or processing instructon.

The condition below:

//Element[@attribute1="abc" and @attribute2="xyz" and Data]

checks for the existence of the element Data within Element and not for element value Data.

Instead you can use

//Element[@attribute1="abc" and @attribute2="xyz" and text()="Data"]

try this css:

/* Show in default resolution screen*/
#container2 {
width: 960px;
position: relative;
margin:0 auto;
line-height: 1.4em;
}

/* If in mobile screen with maximum width 479px. The iPhone screen resolution is 320x480 px (except iPhone4, 640x960) */    
@media only screen and (max-width: 479px){
    #container2 { width: 90%; }
}

You can't. Variables defined inside a method are local to that method.

If you want to share variables between methods, then you'll need to specify them as member variables of the class. Alternatively, you can pass them from one method to another as arguments (this isn't always applicable).

Looks like you're using instance methods instead of static ones.

If you don't want to create an object, you should declare all your methods static, so something like

private static void methodName(Argument args...)

If you want a variable to be accessible by all these methods, you should initialise it outside the methods and to limit its scope, declare it private.

private static int[][] array = new int[3][5];

Global variables are usually looked down upon (especially for situations like your one) because in a large-scale program they can wreak havoc, so making it private will prevent some problems at the least.

Also, I'll say the usual: You should try to keep your code a bit tidy. Use descriptive class, method and variable names and keep your code neat (with proper indentation, linebreaks etc.) and consistent.

Here's a final (shortened) example of what your code should be like:

public class Test3 {
    //Use this array in your methods
    private static int[][] scores = new int[3][5];

    /* Rather than just "Scores" name it so people know what
     * to expect
     */
    private static void createScores() {
        //Code...
    }
    //Other methods...

    /* Since you're now using static methods, you don't 
     * have to initialise an object and call its methods.
     */
    public static void main(String[] args){
        createScores();
        MD();   //Don't know what these do
        sumD(); //so I'll leave them.
    }
}

Ideally, since you're using an array, you would create the array in the main method and pass it as an argument across each method, but explaining how that works is probably a whole new question on its own so I'll leave it at that.

If you are trying to find the difference between timestamps that are in pandas columns, the the answer is fairly simple. If you need it in days or seconds then

# For difference in days:
df['diff_in_days']=(df['timestamp2'] - df['timestamp1']).dt.days
# For difference in seconds
df['diff_in_seconds']=(df['timestamp2'] - df['timestamp1']).dt.seconds

Now minute is tricky as dt.minute works only on datetime64[ns] dtype. whereas the column generated from subtracting two datetimes has format

AttributeError: 'TimedeltaProperties' object has no attribute 'm8'

So like mentioned by many above to get the actual value of the difference in minute you have to do:

df['diff_in_min']=df['diff_in_seconds']/60

But if just want the difference between the minute parts of the two timestamps then do the following

#convert the timedelta to datetime and then extract minute
df['diff_in_min']=(pd.to_datetime(df['timestamp2']-df['timestamp1'])).dt.minute

You can also read the article https://docs.python.org/3.4/library/datetime.html and see section 8.1.2 you'll see the read only attributes are only seconds,days and milliseconds. And this settles why the minute function doesn't work directly.

To create a table on the fly us this syntax:

SELECT *
INTO A
FROM dbo.myView

tl;dr

LocalDate.parse( 
    "01-23-2017" , 
    DateTimeFormatter.ofPattern( "MM-dd-uuuu" )
)

Details

I have a java.util.Date in the format yyyy-mm-dd

As other mentioned, the Date class has no format. It has a count of milliseconds since the start of 1970 in UTC. No strings attached.

java.time

The other Answers use troublesome old legacy date-time classes, now supplanted by the java.time classes.

If you have a java.util.Date, convert to a Instant object. The Instant class represents a moment on the timeline in UTC with a resolution of nanoseconds (up to nine (9) digits of a decimal fraction).

Instant instant = myUtilDate.toInstant();

Time zone

The other Answers ignore the crucial issue of time zone. Determining a date requires a time zone. For any given moment, the date varies around the globe by zone. A few minutes after midnight in Paris France is a new day, while still “yesterday” in Montréal Québec.

Define the time zone by which you want context for your Instant.

ZoneId z = ZoneId.of( "America/Montreal" );

Apply the ZoneId to get a ZonedDateTime.

ZonedDateTime zdt = instant.atZone( z );

LocalDate

If you only care about the date without a time-of-day, extract a LocalDate.

LocalDate localDate = zdt.toLocalDate();

To generate a string in standard ISO 8601 format, YYYY-MM-DD, simply call toString. The java.time classes use the standard formats by default when generating/parsing strings.

String output = localDate.toString();

2017-01-23

If you want a MM-DD-YYYY format, define a formatting pattern.

DateTimeFormatter f = DateTimeFormatter.ofPattern( "MM-dd-uuuu" );
String output = localDate.format( f );

Note that the formatting pattern codes are case-sensitive. The code in the Question incorrectly used mm (minute of hour) rather than MM (month of year).

Use the same DateTimeFormatter object for parsing. The java.time classes are thread-safe, so you can keep this object around and reuse it repeatedly even across threads.

LocalDate localDate = LocalDate.parse( "01-23-2017" , f );

About java.time

The java.time framework is built into Java 8 and later. These classes supplant the troublesome old legacy date-time classes such as java.util.Date, Calendar, & SimpleDateFormat.

The Joda-Time project, now in maintenance mode, advises migration to the java.time classes.

To learn more, see the Oracle Tutorial. And search Stack Overflow for many examples and explanations. Specification is JSR 310.

Where to obtain the java.time classes?

• Java SE 8 and SE 9 and later
  • Built-in.
  • Part of the standard Java API with a bundled implementation.
  • Java 9 adds some minor features and fixes.
• Java SE 6 and SE 7
  • Much of the java.time functionality is back-ported to Java 6 & 7 in ThreeTen-Backport.
• Android
  • The ThreeTenABP project adapts ThreeTen-Backport (mentioned above) for Android specifically.
  • See How to use ThreeTenABP….

The ThreeTen-Extra project extends java.time with additional classes. This project is a proving ground for possible future additions to java.time. You may find some useful classes here such as Interval, YearWeek, YearQuarter, and more.

You can use LINQ to convert your collection to an array and then invoke Array.ForEach():

Array.ForEach(MyCollection.ToArray(), item=>item.DoSomeStuff());

Obviously this will not work with collections of structs or inbuilt types like integers or strings.

Using XML helped me in getting rows separated with commas. For the extra comma we can use the replace function of SQL Server. Instead of adding a comma, use of the AS 'data()' will concatenate the rows with spaces, which later can be replaced with commas as the syntax written below.

REPLACE(
        (select FName AS 'data()'  from NameList  for xml path(''))
         , ' ', ', ') 

It may be tough to find best practices since most systems with APIs don't accommodate for this scenario, because it is an extreme edge, or they don't typically delete records (Facebook, Twitter). Facebook actually says each "page" may not have the number of results requested due to filtering done after pagination. https://developers.facebook.com/blog/post/478/

If you really need to accommodate this edge case, you need to "remember" where you left off. jandjorgensen suggestion is just about spot on, but I would use a field guaranteed to be unique like the primary key. You may need to use more than one field.

Following Facebook's flow, you can (and should) cache the pages already requested and just return those with deleted rows filtered if they request a page they had already requested.

I am also getting same error. Finally i have found the solution.

We can search odbc in our local program and check for version of odbc. In my case i have version 17 and 11 so. i have used 17 in connection string

'DRIVER={ODBC Driver 17 for SQL Server}'

Best Method I have tried instead of using any libraries

public Bitmap getbmpfromURL(String surl){
    try {
        URL url = new URL(surl);
        HttpURLConnection urlcon = (HttpURLConnection) url.openConnection();
        urlcon.setDoInput(true);
        urlcon.connect();
        InputStream in = urlcon.getInputStream();
        Bitmap mIcon = BitmapFactory.decodeStream(in);
        return  mIcon;
    } catch (Exception e) {
        Log.e("Error", e.getMessage());
        e.printStackTrace();
        return null;
    }
}

Have you used another UI thread? You shouldn't use more than 1 UI thread and make it look like a sandwich. Doing this will cause memory leaks.

I have solved a similar issue 2 days ago...

To keep things short: The main thread can have many UI threads to do multiple works, but if one sub-thread containing a UI thread is inside it, The UI thread may not have finished its work yet while it's parent thread has already finished its work, this causes memory leaks.

For example...for Fragment & UI application...this will cause memory leaks.

getActivity().runOnUiThread(new Runnable(){

   public void run() {//No.1

  ShowDataScreen();

getActivity().runOnUiThread(new Runnable(){

    public void run() {//No.2

Toast.makeText(getActivity(), "This is error way",Toast.LENGTH_SHORT).show();

    }});// end of No.2 UI new thread

}});// end of No.1 UI new thread

My solution is rearrange as below:

getActivity().runOnUiThread(new Runnable(){

   public void run() {//No.1

ShowDataScreen();

}});// end of No.1 UI new thread        

getActivity().runOnUiThread(new Runnable(){

   public void run() {//No.2

Toast.makeText(getActivity(), "This is correct way",Toast.LENGTH_SHORT).show();

}});// end of No.2 UI new thread

for you reference.

I am Taiwanese, I am glad to answer here once more.

1. Include the Open Graph XML namespace extension to your HTML declaration

<html xmlns="http://www.w3.org/1999/xhtml"
      xmlns:fb="http://ogp.me/ns/fb#">

2. Inside your <head></head> use the following meta tag to define the image you want to use

<meta property="og:image" content="fully_qualified_image_url_here" />

Read more about open graph protocol here.

After doing the above, use the Facebook "Object Debugger" if the image does not show up correctly. Also note the first time shared it still won't show up unless height and width are also specified, see Share on Facebook - Thumbnail not showing for the first time

php.net says:

Microseconds (added in PHP 5.2.2). Note that date() will always generate 000000 since it takes an integer parameter, whereas DateTime::format() does support microseconds if DateTime was created with microseconds.

So use as simple:

$micro_date = microtime();
$date_array = explode(" ",$micro_date);
$date = date("Y-m-d H:i:s",$date_array[1]);
echo "Date: $date:" . $date_array[0]."<br>";

Recommended and use dateTime() class from referenced:

$t = microtime(true);
$micro = sprintf("%06d",($t - floor($t)) * 1000000);
$d = new DateTime( date('Y-m-d H:i:s.'.$micro, $t) );

print $d->format("Y-m-d H:i:s.u"); // note at point on "u"

Note u is microseconds (1 seconds = 1000000 µs).

Another example from php.net:

$d2=new DateTime("2012-07-08 11:14:15.889342");

Reference of dateTime() on php.net

I've answered on question as short and simplify to author. Please see for more information to author: getting date format m-d-Y H:i:s.u from milliseconds

I think you need to have strings as the data values. It's likely something internally within jQuery that isn't encoding/serializing correctly the To & From Objects.

Try:

var data = {
    from : from.val(),
    to : to.val(),
    speed : speed
};

Notice also on the lines:

$(from).css(...
$(to).css(

You don't need the jQuery wrapper as To & From are already jQuery objects.

For Bootstrap and Less users, there is a mixin .placeholder:

// Placeholder text
// -------------------------
.placeholder(@color: @placeholderText) {
  &:-moz-placeholder {
    color: @color;
  }
  &:-ms-input-placeholder {
    color: @color;
  }
  &::-webkit-input-placeholder {
    color: @color;
  }
}

Disable the firewall and try to connect.

If that works, then enable the firewall and

Windows Defender Firewall -> Advanced Settings -> Inbound Rules(Right Click) -> New Rules -> Port -> Allow Port 1433 (Public and Private) -> Add

Do the same for Outbound Rules.

Then Try again.

Here is best solution for this issue: In View add all the ID (Keys). Consider having multiple tables named (First, Second and Third)

@Html.HiddenFor(model=>model.FirstID)
@Html.HiddenFor(model=>model.SecondID)
@Html.HiddenFor(model=>model.Second.SecondID)
@Html.HiddenFor(model=>model.Second.ThirdID)
@Html.HiddenFor(model=>model.Second.Third.ThirdID)

In C# code,

[HttpPost]
public ActionResult Edit(First first)
{
  if (ModelState.Isvalid)
  {
    if (first.FirstID > 0)
    {
      datacontext.Entry(first).State = EntityState.Modified;
      datacontext.Entry(first.Second).State = EntityState.Modified;
      datacontext.Entry(first.Second.Third).State = EntityState.Modified;
    }
    else
    {
      datacontext.First.Add(first);
    }
    datacontext.SaveChanges();
    Return RedirectToAction("Index");
  }

 return View(first);
}

you can use this code for showing or print :

<byte_object>.decode("utf-8")

and you can use this for encode or saving :

<str_object>.encode('utf-8')

Read this documentation of moment.js here. See below example and output where I convert GMT time to local time (my zone is IST) and then I convert local time to GMT.

// convert GMT to local time
console.log('Server time:' + data[i].locationServerTime)
let serv_utc = moment.utc(data[i].locationServerTime, "YYYY-MM-DD HH:mm:ss").toDate();
console.log('serv_utc:' + serv_utc)
data[i].locationServerTime = moment(serv_utc,"YYYY-MM-DD HH:mm:ss").tz(self.zone_name).format("YYYY-MM-DD HH:mm:ss");
console.log('Converted to local time:' + data[i].locationServerTime)

// convert local time to GMT
console.log('local time:' + data[i].locationServerTime)
let serv_utc = moment(data[i].locationServerTime, "YYYY-MM-DD HH:mm:ss").toDate();
console.log('serv_utc:' + serv_utc)
data[i].locationServerTime = moment.utc(serv_utc,"YYYY-MM-DD HH:mm:ss").format("YYYY-MM-DD HH:mm:ss");
console.log('Converted to server time:' + data[i].locationServerTime)

Output is

Server time:2019-12-19 09:28:13
serv_utc:Thu Dec 19 2019 14:58:13 GMT+0530 (India Standard Time)

Following on from Jakub's answer. git archive produces a tar or zip archive, so you need to pipe the output through tar to get the file content:

git archive --remote=git://git.foo.com/project.git HEAD:path/to/directory filename | tar -x

Will save a copy of 'filename' from the HEAD of the remote repository in the current directory.

The :path/to/directory part is optional. If excluded, the fetched file will be saved to <current working dir>/path/to/directory/filename

In addition, if you want to enable use of git archive --remote on Git repositories hosted by git-daemon, you need to enable the daemon.uploadarch config option. See https://kernel.org/pub/software/scm/git/docs/git-daemon.html

There can be a problem with "\00a0" in pseudo-elements because it takes the text-decoration of its defining element, so that, for example, if the defining element is underlined, then the white space of the pseudo-element is also underlined.

The easiest way to deal with this is to define the opacity of the pseudo-element to be zero, eg:

element:before{
  content: "_";
  opacity: 0;
}

You could try adding the following script code to implement this:

if(CompareDates(smallDate,largeDate,'-') == 0) {
    alert('Selected date must be current date or previous date!');
return false;
}

function CompareDates(smallDate,largeDate,separator) {
    var smallDateArr = Array();
    var largeDateArr = Array(); 
    smallDateArr = smallDate.split(separator);
    largeDateArr = largeDate.split(separator);  
    var smallDt = smallDateArr[0];
    var smallMt = smallDateArr[1];
    var smallYr = smallDateArr[2];  
    var largeDt = largeDateArr[0];
    var largeMt = largeDateArr[1];
    var largeYr = largeDateArr[2];

    if(smallYr>largeYr) 
        return 0;
else if(smallYr<=largeYr && smallMt>largeMt)
    return 0;
else if(smallYr<=largeYr && smallMt==largeMt && smallDt>largeDt)
    return 0;
else 
    return 1;
}

You'd need to be careful as onBlur has some caveats in IE11 (How to use relatedTarget (or equivalent) in IE?, https://developer.mozilla.org/en-US/docs/Web/API/MouseEvent/relatedTarget).

There is, however, no way to use onFocusOut in React as far as I can tell. See the issue on their github https://github.com/facebook/react/issues/6410 if you need more information.

For Android there is the addition of target-density tag.

target-densitydpi=device-dpi

So, the code would look like

<meta name="viewport" content="width=device-width, target-densitydpi=device-dpi, initial-scale=0, maximum-scale=1, user-scalable=yes" />

Please note, that I believe this addition is only for Android (but since you have answers, I felt this was a good extra) but this should work for most mobile devices.

$file = Get-Item -Path "c:/foo/foobar.txt"
$file.Name

Works with both relative an absolute paths

This error can occur even if the name of the function is valid if some mandatory arguments are missing (i.e you did not provide enough arguments).
I got this in an Rcpp context, where I wrote a C++ function with optionnal arguments, and did not provided those arguments in R. It appeared that optionnal arguments from the C++ were seen as mandatory by R. As a result, R could not find a matching function for the correct name but an incorrect number of arguments.

Rcpp Function : SEXP RcppFunction(arg1, arg2=0) {}
R Calls :
RcppFunction(0) raises the error
RcppFunction(0, 0) does not

Vartec's answer doesn't read all lines, so I made a version that did:

def run_command(command):
    p = subprocess.Popen(command,
                         stdout=subprocess.PIPE,
                         stderr=subprocess.STDOUT)
    return iter(p.stdout.readline, b'')

Usage is the same as the accepted answer:

command = 'mysqladmin create test -uroot -pmysqladmin12'.split()
for line in run_command(command):
    print(line)

run this:

rm -rf node_modules && npm cache clear && npm install

Node will install from whatever is cached. So if you clear everything out first, then NPM use 0.10.xx, it will revert properly.

titleForHeaderInSection is a delegate method of UITableView so to apply header text of section write as follows,

              return @"Hello World";

As the existing answers mentioned, LEA has the advantages of performing memory addressing arithmetic without accessing memory, saving the arithmetic result to a different register instead of the simple form of add instruction. The real underlying performance benefit is that modern processor has a separate LEA ALU unit and port for effective address generation (including LEA and other memory reference address), this means the arithmetic operation in LEA and other normal arithmetic operation in ALU could be done in parallel in one core.

Check this article of Haswell architecture for some details about LEA unit: http://www.realworldtech.com/haswell-cpu/4/

Another important point which is not mentioned in other answers is LEA REG, [MemoryAddress] instruction is PIC (position independent code) which encodes the PC relative address in this instruction to reference MemoryAddress. This is different from MOV REG, MemoryAddress which encodes relative virtual address and requires relocating/patching in modern operating systems (like ASLR is common feature). So LEA can be used to convert such non PIC to PIC.

regular expressions make this easy ...

[A-Z] will match exactly one character between A and Z

\d+ will match one or more digits

() group things (and also return things... but for now just think of them grouping)

+ selects 1 or more

I have set OnGroupExpandListener and override onGroupExpand() as:

and use setSelectionFromTop() method which Sets the selected item and positions the selection y pixels from the top edge of the ListView. (If in touch mode, the item will not be selected but it will still be positioned appropriately.) (android docs)

    yourlist.setOnGroupExpandListener (new ExpandableListView.OnGroupExpandListener()
    {

        @Override
        public void onGroupExpand(int groupPosition) {

            expList.setSelectionFromTop(groupPosition, 0);
            //your other code
        }
    });

Maybe python changed since this question, all of the below seem to work well

Python2.7

int(1324343032.324325235 * 1000) / 1000.0
float(int(1324343032.324325235 * 1000)) / 1000
round(int(1324343032.324325235 * 1000) / 1000.0,3)
# result for all of the above is 1324343032.324

Your comparison function is not even wrong.

Its arguments should be the type stored in the range, i.e. std::pair<K,V>, not const void*.

It should return bool not a positive or negative value. Both (bool)1 and (bool)-1 are true so your function says every object is ordered before every other object, which is clearly impossible.

You need to model the less-than operator, not strcmp or memcmp style comparisons.

See StrictWeakOrdering which describes the properties the function must meet.

I wanted to share a solution I came up with using jQuery that works if you have multiple YouTube videos embedded on a single page. In my case, I have defined a modal popup for each video as follows:

<div id="videoModalXX">
...
    <button onclick="stopVideo(videoID);" type="button" class="close"></button>
    ...
    <iframe width="90%" height="400" src="//www.youtube-nocookie.com/embed/video_id?rel=0&enablejsapi=1&version=3" frameborder="0" allowfullscreen></iframe>
...
</div>

In this case, videoModalXX represents a unique id for the video. Then, the following function stops the video:

function stopVideo(id)
{
    $("#videoModal" + id + " iframe")[0].contentWindow.postMessage('{"event":"command","func":"pauseVideo","args":""}', '*');
}

I like this approach because it keeps the video paused where you left off in case you want to go back and continue watching later. It works well for me because it's looking for the iframe inside of the video modal with a specific id. No special YouTube element ID is required. Hopefully, someone will find this useful as well.
